Perioperative medicine training resources: U3M7: Psychological wellbeing and surgical outcomes

Abstract
Study design: Retrospective.

Objective: To investigate the prevalence of decisional regret among older adults undergoing surgery for adult spinal deformity (ASD).

Summary of background data: Among older adults (≥65 years old), ASD is a leading cause of disability, with a population prevalence of 60% to 70%. While surgery is beneficial and results in functional improvement, in over 20% of older adults outcomes from surgery are less desirable.

Methods: Older adults with ASD who underwent spinal surgery at a quaternary medical center from January 1, 2016 to March 1, 2019, were enrolled in this study. Patients were categorized into medium/high or low-decisional regret cohorts based on their responses to the Ottawa decision regret questionnaire. Decisional regret assessments were completed 24 months after surgery. The primary outcome measure was prevalence of decisional regret after surgery. Factors associated with high decisional regret were analyzed by multivariate logistic regression.

Results: A total of 155 patients (mean age, 69.5 yrs) met the study inclusion criteria. Overall, 80% agreed that having surgery was the right decision for them, and 77% would make the same choice in future. A total of 21% regretted the choice that they made, and 21% responded that surgery caused them harm. Comparing patient cohorts reporting medium/high- versus low-decisional regret, there were no differences in baseline demographics, comorbidities, invasiveness of surgery, length of stay, discharge disposition, or extent of functional improvement 12-months after surgery. After adjusting for sex, American Society of Anesthesiologists score, invasiveness of surgery, and presence of a postoperative complication, older adults with preoperative depression had a 4.0 fold increased odds of high-decisional regret (P = 0.04). Change in health related quality of life measures were similar between all groups at 12-months after surgery.

Conclusion: While the majority of older adults were appropriately counseled and satisfied with their decision, one-in-five older adults regret their decision to undergo surgery. Preoperative depression was associated with medium/high decisional regret on multivariate analysis.Level of Evidence: 4.

Abstract in English, Spanish, French
Anxiety disorders (generalized anxiety disorder, panic disorder/agoraphobia, social anxiety disorder, and others) are the most prevalent psychiatric disorders, and are associated with a high burden of illness. Anxiety disorders are often underrecognized and undertreated in primary care. Treatment is indicated when a patient shows marked distress or suffers from complications resulting from the disorder. The treatment recommendations given in this article are based on guidelines, meta-analyses, and systematic reviews of randomized controlled studies. Anxiety disorders should be treated with psychological therapy, pharmacotherapy, or a combination of both. Cognitive behavioral therapy can be regarded as the psychotherapy with the highest level of evidence. First-line drugs are the selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors. Benzodiazepines are not recommended for routine use. Other treatment options include pregabalin, tricyclic antidepressants, buspirone, moclobemide, and others. After remission, medications should be continued for 6 to 12 months. When developing a treatment plan, efficacy, adverse effects, interactions, costs, and the preference of the patient should be considered.

Abstract in English, Spanish, French
Anxiety disorders, including panic disorder with or without agoraphobia, generalized anxiety disorder, social anxiety disorder, specific phobias, and separation anxiety disorder, are the most prevalent mental disorders and are associated with immense health care costs and a high burden of disease. According to large population-based surveys, up to 33.7% of the population are affected by an anxiety disorder during their lifetime. Substantial underrecognition and undertreatment of these disorders have been demonstrated. There is no evidence that the prevalence rates of anxiety disorders have changed in the past years. In cross-cultural comparisons, prevalence rates are highly variable. It is more likely that this heterogeneity is due to differences in methodology than to cultural influences. Anxiety disorders follow a chronic course; however, there is a natural decrease in prevalence rates with older age. Anxiety disorders are highly comorbid with other anxiety disorders and other mental disorders.

Abstract
Public mental health involves a population approach to mental health, and includes treatment of mental disorder, prevention of associated impacts, prevention of mental disorder and promotion of mental well-being, including for those people recovering from mental disorder. Such interventions can result in a broad range of impacts and associated economic savings even in the short term. However, even in high-income countries only a minority of people with mental disorder receive any treatment, while provision is far less in low- and middle-income countries. Coverage of interventions to prevent mental disorder and promote mental well-being is far less even in high-income countries, despite such interventions being required for sustainable reduction in the burden of mental disorder. This implementation gap results in a broad set of impacts and associated economic costs. Mental health needs assessments represent an important framework and mechanism to address this implementation gap - in low- and middle-income as well as high-income countries. Training and support to perform mental health needs assessments is important, as is the use of information derived from such assessments to more effectively advocate for the required level of resources to address the implementation gap. Such a public health approach to mental health represents an opportunity for psychiatrists to advocate more effectively for resources at both the local and national level. This can improve the coverage and outcomes of a range of public mental health interventions that result in broad impacts and associated economic savings, which can be estimated.

Abstract
Purpose: The purpose of this study was to examine scale dimensionality, reliability, invariance, targeting, continuity, cutoff scores, and diagnostic use of the Geriatric Depression Scale-Short Form (GDS-SF) over time with a sample of 177 English-speaking U.S. elders.

Design and methods: An item response theory, Rasch analysis, was conducted with data from a larger study that implemented 3 interventions and collected data at 3 time points (prior to intervention, after intervention, and a year following the end of intervention).

Results: A unidimensional structure was found in this study to adequately fit the data. There appears to be significant differential item functioning, with up to one third of the items indicating that the items have different meanings for different groups of participants. As a screening tool, the GDS-SF is more likely to discriminate between older adults who have a "moderate" level of depression than between those with mild depression and no diagnosed depression.

Implications: We would recommend that the GDS-SF not be used as the sole method of screening for depression but incorporated into other clinical knowledge related to the geriatric patient in question, given that not all items are equally functional. The GDS-SF may be less effective as a screening tool but could be better used to detect a change in moderate levels of depression. Clinicians may also benefit by identifying person responses that misfit. If an individual provides responses that are atypical, the person might be referred to provide a more in-depth assessment of mental health status.

Abstract
State and trait anxiety theory and assessment are reviewed. The person (trait anxiety) and the situation are important in determining levels of state anxiety. The facet of trait anxiety and the stressful situation must be congruent in order to evoke increases in state anxiety. The multidimensional interaction model is reviewed and empirical research is presented. A discussion of anxiety viewed in a dimensional versus a categorical conceptualization is presented. Misconceptions regarding the multidimensionality of trait anxiety are discussed. Finally, it is concluded that anxiety should be viewed as a dimensional construct and that the multidimensionality of state and trait anxiety should be considered in both theory and assessment.

Abstract
The dominant model of disease today is biomedical, and it leaves no room within tis framework for the social, psychological, and behavioral dimensions of illness. A biopsychosocial model is proposed that provides a blueprint for research, a framework for teaching, and a design for action in the real world of health care.

Abstract
With increasing frequency, patients are being asked to make complex decisions about cancer screening, prevention, and treatment. These decisions are fraught with emotion and cognitive difficulty simultaneously. Many Americans have low numeracy skills making the cognitive demands even greater whenever, as is often the case, patients are presented with risk statistics and asked to make comparisons between the risks and benefits of multiple options and to make informed medical decisions. In this commentary, we highlight 10 methods that have been empirically shown to improve patients' understanding of risk and benefit information and/or their decision making. The methods range from presenting absolute risks using frequencies (rather than presenting relative risks) to using a risk format that clarifies how treatment changes risks from preexisting baseline levels to using plain language. We then provide recommendations for how health-care providers and health educators can best to communicate this complex medical information to patients, including using plain language, pictographs, and absolute risks instead of relative risks.

Abstract
Purpose: This paper identifies predictors of recovery trajectories of quality of life (QoL), health status and personal wellbeing in the two years following colorectal cancer surgery.

Methods: 872 adults receiving curative intent surgery during November 2010 to March 2012. Questionnaires at baseline, 3, 9, 15, 24 months post-surgery assessed QoL, health status, wellbeing, confidence to manage illness-related problems (self-efficacy), social support, co-morbidities, socio-demographic, clinical and treatment characteristics. Group-based trajectory analyses identified distinct trajectories and predictors for QoL, health status and wellbeing.

Results: Four recovery trajectories were identified for each outcome. Groups 1 and 2 fared consistently well (scores above/within normal range); 70.5% of participants for QoL, 33.3% health status, 77.6% wellbeing. Group 3 had some problems (24.2% QoL, 59.3% health, 18.2% wellbeing); Group 4 fared consistently poorly (5.3% QoL, 7.4% health, 4.2% wellbeing). Higher pre-surgery depression and lower self-efficacy were significantly associated with poorer trajectories for all three outcomes after adjusting for other important predictors including disease characteristics, stoma, anxiety and social support.

Conclusions: Psychosocial factors including self-efficacy and depression before surgery predict recovery trajectories in QoL, health status and wellbeing following colorectal cancer treatment independent of treatment or disease characteristics. This has significant implications for colorectal cancer management as appropriate support may be improved by early intervention resulting in more positive recovery experiences.

Abstract
Background: The interaction of depression and anesthesia and surgery may result in significant increases in morbidity and mortality of patients. Major depressive disorder is a frequent complication of surgery, which may lead to further morbidity and mortality.

Literature search: Several electronic data bases, including PubMed, were searched pairing "depression" with surgery, postoperative complications, postoperative cognitive impairment, cognition disorder, intensive care unit, mild cognitive impairment and Alzheimer's disease.

Review of the literature: The suppression of the immune system in depressive disorders may expose the patients to increased rates of postoperative infections and increased mortality from cancer. Depression is commonly associated with cognitive impairment, which may be exacerbated postoperatively. There is evidence that acute postoperative pain causes depression and depression lowers the threshold for pain. Depression is also a strong predictor and correlate of chronic post-surgical pain. Many studies have identified depression as an independent risk factor for development of postoperative delirium, which may be a cause for a long and incomplete recovery after surgery. Depression is also frequent in intensive care unit patients and is associated with a lower health-related quality of life and increased mortality. Depression and anxiety have been widely reported soon after coronary artery bypass surgery and remain evident one year after surgery. They may increase the likelihood for new coronary artery events, further hospitalizations and increased mortality. Morbidly obese patients who undergo bariatric surgery have an increased risk of depression. Postoperative depression may also be associated with less weight loss at one year and longer. The extent of preoperative depression in patients scheduled for lumbar discectomy is a predictor of functional outcome and patient's dissatisfaction, especially after revision surgery. General postoperative mortality is increased.

Conclusions: Depression is a frequent cause of morbidity in surgery patients suffering from a wide range of conditions. Depression may be identified through the use of Patient Health Questionnaire-9 or similar instruments. Counseling interventions may be useful in ameliorating depression, but should be subject to clinical trials.

Abstract
Although the everyday decision-making of clinically anxious individuals is clearly influenced by their excessive fear and worry, the relationship between anxiety and decision-making remains relatively unexplored in neuroeconomic studies. In this review, we attempt to explore the role of anxiety in decision-making with a neuroeconomic approach. We first review the neural systems mediating fear and anxiety, which overlap with a network of brain regions implicated in studies of economic decision-making. We then discuss the potential influence of cognitive biases associated with anxiety upon economic choice, focusing on a set of decision-making biases involving choice in the face of potential aversive outcomes. We propose that the neural circuitry supporting fear learning and regulation may mediate the influence of anxiety upon choice and suggest that techniques for altering fear and anxiety may also change decisions.

Abstract
Post-traumatic stress disorder (PTSD) is a psychological disturbance resulting from exposure to a traumatic experience that lasts more than one month. PTSD in the United States has a lifetime prevalence of 3.4% to 26.9% in civilians and 7.7% to 17.0% in military veterans. Emergence agitation (EA) and emergence delirium (ED) are known phenomena in the postanesthetic period. PTSD is closely associated with EA following anesthesia. In addition, EA in patients with PTSD can be severe and challenging to manage. EA is a risk to both patients and healthcare workers. Furthermore, EA has been shown to increase the overall risk of postoperative delirium and complications. Currently, studies on the anesthetic management of patients with PTSD are scarce and limited to case reports. Here, we present a summary of several important published case reports and a brief review of the literature regarding the anesthetic management of PTSD and EA to aid in managing patients with PTSD. In addition, we present two cases of successful EA prevention in patients with severe PTSD. From our review of the literature and the successful prevention of EA in our patients with severe PTSD, we conclude that there is an increased need for overall awareness among anesthesia and perioperative care providers of the effect of PTSD on EA. Anesthesia providers should aim to include as many management recommendations as possible and avoid possible triggers of EA via a multidisciplinary approach. Multiple pharmacological agents have been used for the anesthetic management of PTSD with varying results. Of the agents studied, dexmedetomidine has been found to be the most consistently beneficial.

Abstract
Research has shown that personality is associated with anxiety levels in the general population. However, little is known about the relationship between personality and preoperative anxiety and the subsequent health outcomes in patients undergoing surgery. Therefore, this review aimed to identify studies that explored the relationship between personality traits and preoperative anxiety, as well as their association with postoperative outcomes. Existing literature shows that anxiety may play an intermediary role in the relationship between personality and postoperative outcomes. Severe anxiety may partially explain the adverse effects of certain personality traits, such as neuroticism, on postoperative outcomes. However, the relationship between personality traits, preoperative anxiety, and postoperative outcomes remains unclear. Interventions such as clinical evaluation, preoperative counseling, and management strategies can be of great value in identifying and resolving patients' anxiety and negative emotions to improve postoperative outcomes.

Abstract
People with a learning disability can experience significant problems in accessing healthcare and this may be partly reflected in worse health outcomes compared with the general population, including a shorter life expectancy. The Equality Act (2010) requires that organisations and individuals make changes to the way services are provided for all disabled people to mitigate, as far as possible, any disadvantage they may face in accessing these services. These changes are termed 'reasonable adjustments'. This article describes the reasonable adjustments that can be made to facilitate the admission of an adult surgical patient with a learning disability, and therefore reduce health inequality. Each stage of a patient's journey through the hospital needs to be anticipated and planned for. Many of these changes are not only applicable to the wider care of people with a learning disability, but also to any person who lacks capacity and who is struggling to access healthcare. Key recommendations include the development of assessment tools, pathways and policies specific to the learning disabled patient; identification of key personnel including a learning disability lead, an acute liaison learning disability nurse, pre-assessment and operating theatre personnel and ward learning disability champions; regular multidisciplinary team meetings for planning and best interest assessments; and establishing an electronic alert on the patient administration system to identify learning disabled patients. The anaesthetist, operating theatre and learning disability teams play a pivotal role in ensuring individualised admission plans are made for patients with a learning disability to reduce these healthcare inequalities and improve peri-operative care.

Abstract
Objectives: Emotional distress can be a potential barrier to shared decision making (SDM), yet affect is typically not systematically assessed in medical consultation. We examined whether urological patients report anxiety or depression prior to a consultation and if emotional distress predicts decisional conflict thereafter.

Methods: We recruited a large sample of urological outpatients (N = 397) with a range of different diagnoses (42 % oncological). Prior to a medical consultation, patients filled in questionnaires, including the Hospital Anxiety and Depression Scale. After the consultation, patients completed the Decisional Conflict Scale. We scored the rate of anxiety and depression in our sample and conducted multiple regression analysis to examine if emotional distress before the consultation predicts decisional conflict thereafter.

Results: About a quarter of patients reported values at or above cut-off for clinically relevant emotional distress. Emotional distress significantly predicted a higher degree of decisional conflict. There were no differences in emotional distress between patients with and without uro-oncological diagnosis.

Conclusions: Emotional distress is common in urology patients - oncological as well as non-oncological. It predicts decisional conflict after physician consultation.

Practice implications: Emotional distress should be systematically assessed in clinical consultations. This may improve the process and outcome of SDM.

Abstract
Objective: While considerable attention has focused on improving the detection of depression, assessment of severity is also important in guiding treatment decisions. Therefore, we examined the validity of a brief, new measure of depression severity.

Measurements: The Patient Health Questionnaire (PHQ) is a self-administered version of the PRIME-MD diagnostic instrument for common mental disorders. The PHQ-9 is the depression module, which scores each of the 9 DSM-IV criteria as "0" (not at all) to "3" (nearly every day). The PHQ-9 was completed by 6,000 patients in 8 primary care clinics and 7 obstetrics-gynecology clinics. Construct validity was assessed using the 20-item Short-Form General Health Survey, self-reported sick days and clinic visits, and symptom-related difficulty. Criterion validity was assessed against an independent structured mental health professional (MHP) interview in a sample of 580 patients.

Results: As PHQ-9 depression severity increased, there was a substantial decrease in functional status on all 6 SF-20 subscales. Also, symptom-related difficulty, sick days, and health care utilization increased. Using the MHP reinterview as the criterion standard, a PHQ-9 score > or =10 had a sensitivity of 88% and a specificity of 88% for major depression. PHQ-9 scores of 5, 10, 15, and 20 represented mild, moderate, moderately severe, and severe depression, respectively. Results were similar in the primary care and obstetrics-gynecology samples.

Conclusion: In addition to making criteria-based diagnoses of depressive disorders, the PHQ-9 is also a reliable and valid measure of depression severity. These characteristics plus its brevity make the PHQ-9 a useful clinical and research tool.

Abstract
The pre-operative optimisation of comorbidities is increasingly recognised as an important element of the pre-operative pathway. These efforts have primarily focused on physical comorbidities such as anaemia and the optimisation of exercise and nutrition. However, there is a growing recognition of the importance of psychological morbidity. Increasingly, evidence suggests that psychological factors have an impact on surgical outcomes in both the short and long term. Pre-operative anxiety, depression and low self-efficacy are consistently associated with worse physiological surgical outcomes and postoperative quality of life. This has led to the emergence of psychological prehabilitation and the trimodal approach to prehabilitation, incorporating psychological intervention as well as exercise and nutritional optimisation. However, there is currently insufficient evidence to be sure that pre-operative psychological interventions are of benefit, or which interventions are most effective, because their impact has been mixed. There is an urgent need for high quality, contemporaneous prospective trials with baseline psychological evaluation, well-described interventions and agreement on the most appropriate psychological, quality of life and physiological outcomes measures.

Abstract
Introduction: The aim of the present paper is to establish feasibility and required power of a one-session psychological intervention devoted to increasing patient's self-efficacy and awareness in dealing with anxiety symptoms before major pancreatic cancer surgery.

Methods: Parallel assignment RCT. All consenting patients listed for pancreatic major surgery during day-hospital visits (T0) between June 2017-June 2018 were assigned randomly in blocks of ten to a psychological intervention vs usual care group to be held the day before surgery (T1). The psychological intervention provided the patient the opportunity to increase self-efficacy in dealing with anxiety by talking with a psychologist about personal concerns and learning mindfulness based techniques to cope with anxiety.

Results: 400 patients were randomized into the experimental vs. usual care group. 49 and 65, respectively, completed baseline and post-intervention measures. The dropout rate between day-hospital (T0) and pre-surgery intervention (T1) was high (74.5%) due to several management and organization pitfalls. The main outcome, perceived self-efficacy in managing anxiety, showed a significant increase in the intervention group compared to the control group (p < 0.001), and was related to a reduction in state anxiety (p < 0.001). The intervention group perceived also lower emotional pain (p = 0.03). A power analysis was performed to define the appropriate sample size in a definitive RCT.

Conclusion: Beneath the complexity in retaining patients along their trajectory in pancreatic surgery department, when they had the opportunity to follow a brief psychological intervention, most of them adhered, showing a significant reduction in preoperative emotional distress and less emotional pain perception after surgery. Even if results need caution because of the high attrition rate, we can infer that our psychological intervention has the potential to be proposed in surgical setting, being short, easy to learn and applicable to a wide range of patients.

Clinical trial registration: The trial was registered on ClinicalTrials.gov (identifier: NCT03408002). The full protocol is available from the last author.

Abstract
The purpose of the present study was to assess patients' anxiety level and information requirement in the preoperative phase. During routine preoperative screening, 320 patients were asked to assess their anxiety and information requirement on a six-item questionnaire, the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Two hundred patients also completed Spielberger's State-Trait Anxiety Inventory (STAI-State). Patients were able to complete the questionnaire in less than 2 min. On factor analysis, two factors emerged clearly: anxiety and the need for information. The anxiety scale correlated highly (0.74) with the STAI-State. It emerged that 32% of the patients could be considered as "anxiety cases" and over 80% of patients have a positive attitude toward receiving information. Moreover, results demonstrated that 1) women were more anxious that men; 2) patients with a high information requirement also had a high level of anxiety; 3) patients who had never undergone an operation had a higher information requirement than those who had. The APAIS can provide anesthesiologists with a valid, reliable, and easily applicable instrument for assessing the level of patients' preoperative anxiety and the need for information.

Abstract
Importance: Prescription medications are increasingly used among adults in the United States and many have a potential for causing depression.

Objectives: To characterize use of prescription medications with depression as a potential adverse effect and to assess associations between their use and concurrent depression.

Design, setting, and participants: Five 2-year cycles (2005-2006 through 2013-2014) of the National Health and Nutrition Examination Survey, representative cross-sectional surveys of US adults aged 18 years or older, were analyzed for use of medications with depression as a potential adverse effect. Multivariable logistic regression examined associations between use of these medications and concurrent depression. Analyses were performed among adults overall, excluding antidepressant users, and among adults treated with antidepressants and with hypertension.

Exposures: Prescription medications with depression as a potential adverse effect (listed in Micromedex).

Main outcomes and measures: Prevalence of any use and concurrent use of medications with a potential to cause depression and prevalence of depression (PHQ-9 score ≥10).

Results: The study included 26 192 adults (mean age, 46.2 years [95% CI, 45.6-46.7]; women, 51.1%) and 7.6% (95% CI, 7.1%-8.2%) reported depression. The overall estimated prevalence of use of medications with depression as an adverse effect was 37.2%, increasing from 35.0% (95% CI, 32.2%-37.9%) in the cycle years 2005 and 2006 to 38.4% (95% CI, 36.5%-40.3%) in 2013 and 2014 (P for trend = .03). An estimated 6.9% (95% CI, 6.2%-7.6%) reported use of 3 or more concurrent medications with a potential for depression as an adverse effect in 2005 and 2006 and 9.5% (95% CI, 8.4%-10.7%) reported such use in 2013 and 2014 (P for trend = .001). In adjusted analyses excluding users of antidepressants, the number of medications used with depression as possible adverse effects was associated with increased prevalence of concurrent depression. The estimated prevalence of depression was 15% for those reporting use of 3 or more medications with depression as an adverse effect vs 4.7% for those not using such medications (difference, 10.7% [95% CI, 7.2%-14.1%]). These patterns persisted in analyses restricted to adults treated with antidepressants, among hypertensive adults, and after excluding users of any psychotropic medication.

Conclusions and relevance: In this cross-sectional survey study, use of prescription medications that have depression as a potential adverse effect was common. Use of multiple medications was associated with greater likelihood of concurrent depression.

Abstract
Background: Catastrophic thinking and fear-avoidance belief are negatively influencing severe acute pain following surgery causing delayed ambulation and discharge. We aimed to examine if a preoperative intervention of cognitive-behavioural therapy (CBT) could influence the early postsurgical outcome following lumbar spinal fusion surgery (LSF).

Methods: Ninety patients undergoing LSF due to degenerative spinal disorders were randomly allocated to either the CBT group or the control group. Both groups received surgery and postoperative rehabilitation. In addition, the CBT group received a preoperative intervention focussed on pain coping using a CBT approach. Primary outcome was back pain during the first week (0-10 scale). Secondary outcomes were mobility, analgesic consumption, and length of hospitalisation. Data were retrieved using self-report questionnaires, assessments made by physical therapists and from medical records.

Results: No difference between the groups' self-reported back pain (p = 0.76) was detected. Independent mobility was reached by a significantly larger number of patients in the CBT group than the control group during the first three postoperative days. Analgesic consumption tended to be lower in the CBT group, whereas length of hospitalisation was unaffected by the CBT intervention.

Conclusion: Participation in a preoperative CBT intervention appeared to facilitate mobility in the acute postoperative phase, despite equally high levels of self-reported acute postsurgical pain in the two groups, and a slightly lower intake of rescue analgesics in the CBT group. This may reflect an overall improved ability to cope with pain following participation in the preoperative CBT intervention.

Trial registration: The study was approved by the Danish Protection Agency (2011-41-5899) and the Ethics Committee of the Central Denmark Region (M-20110047). The trial was registered in Current Controlled Trials ( ISRCTN42281022 ).

Abstract
There is a need to assess the contribution of mood disorder, especially anxiety and depression, in order to understand the experience of suffering in the setting of medical practice. Most physicians are aware of this aspect of the illness of their patients but many feel incompetent to provide the patient with reliable information. The Hospital Anxiety And Depression Scale, or HADS, was designed to provide a simple yet reliable tool for use in medical practice. The term 'hospital' in its title suggests that it is only valid in such a setting but many studies conducted throughout the world have confirmed that it is valid when used in community settings and primary care medical practice. It should be emphasised that self-assessment scales are only valid for screening purposes; definitive diagnosis must rest on the process of clinical examination.

Abstract
Preoperative anxiety can influence the intensity of postoperative pain and anesthesia and analgesia requirement. In certain types of surgery, anxiety may even increase postoperative morbidity and mortality. The goal of this narrative review is to remind anesthesiologists that anxiety measurement using specific tools can be done in clinical practice, to present the implications of preoperative anxiety on postoperative patient recovery, and to acknowledge the importance of a dedicated anesthesia plan in the management of anxious adult patients. Preoperative assessment performed several weeks before surgery in an outpatient clinic is a reasonable option to give information about surgery, anesthesia and postoperative pain. This is the time to assess patient preoperative anxiety by using VAS-A. If high anxiety level is detected early, the patient can be referred to a psychologist for preoperative preparation. This is consistent with the guidelines for enhanced recovery after surgeries, which underline the importance of patient-doctor discussion about hospitalization and perioperative care. Patients with preoperative anxiety could benefit from multimodal analgesia, including non-pharmacological methods, such as cognitive therapy and music therapy and relaxation. The authors' opinion is that greater education about preoperative anxiety consequences in the surgical community is needed. A systemized approach and guidelines about the management of preoperative anxiety should be followed.

Abstract
Introduction: Anxiety is a feeling of tension, apprehension, nervousness, fear, discomfort, and high autonomic activity with varying degrees of intensity resulting from anticipation of danger. Post-operative pain is associated with the emotional status, behavioural response, and high anxiety index of patients.This study aimed to assess the effect of preoperative anxiety on Postoperative Pain in Patients Undergoing Elective Surgery.

Methods: An institutional-based prospective cohort study was conducted on patients scheduled for elective surgeries from November 1, 2019, to October 30, 2020, in Dilla University Referral Hospital. Data was collected by pretested questionnaires and analysed by SPSS version 20. Categorical data were analysed by chi-square while Continuous data were analysed by student t-test and Mann Whitney U for parametric and nonparametric data respectively with a P-value of <0.05 was considered as statistically significant.

Result: As our finding revealed patients with high preoperative anxiety experienced significantly increased postoperative pain at 2 h, 4 h, 6 h, and 12 h with the P-value of 0.012, 0.01, 0.001, and 0.002 respectively and total tramadol consumption in a patient with high preoperative anxiety level is 156.5 ± 23.4 while in low anxiety 147.1 ± 39. with a p-value of 0.036.

Conclusion: High preoperative anxiety increased the immediate postoperative pain score and 24 h tramadol consumption. It would be better to decrease preoperative anxiety levels to reduce postoperative pain and 24 h analgesic consumption.

Abstract
Psychological well-being is a core feature of mental health, and may be defined as including hedonic (enjoyment, pleasure) and eudaimonic (meaning, fulfillment) happiness, as well as resilience (coping, emotion regulation, healthy problem solving). To promote psychological well-being, it is helpful to understand the underlying mechanisms associated with this construct and then develop targeted and effective training programs. In this perspective article, we discuss key components and potential brain-body mechanisms related to psychological well-being and propose mindfulness training as a promising way to improve it. Based on a series of randomized controlled trial (RCT) studies of one form of mindfulness training in adolescents and adults, the integrative body-mind training (IBMT), we use IBMT as an exemplar to provide research evidence of the positive effects of mindfulness training on psychological well-being. We focus on one of the mechanisms by which IBMT enhances psychological well-being-the interaction between mind (mindfulness) and body (bodifulness)-which involves both the central nervous system (CNS) and the autonomic nervous system (ANS). We also highlight the role of brain self-control networks, including the anterior cingulate cortex/prefrontal cortex (ACC/PFC), in improving psychological well-being. We suggest that mindfulness training may be a promising program that promotes the synergistic engagement of mind and body to achieve the goals of enhancing psychological well-being.

Abstract
Importance: Clinicians should understand the prevalence of depression and decision regret in patients with head and neck cancer and whether these factors differ with age or frailty.

Objectives: To assess whether age and frailty are associated with preoperative and/or worsening postoperative depression and postoperative decision regret in patients undergoing major head and neck surgery and to identify additional factors associated with depression and decision regret.

Design, setting, and participants: This prospective cohort study was conducted at a single institution, with patients aged 50 years or older undergoing major head and neck surgery recruited from December 1, 2011, to April 30, 2014. Statistical analysis was performed from July 1, 2018, to June 30, 2019.

Main outcomes and measures: Frailty, functional, and geriatric depression assessments were completed before surgery and 3, 6, and 12 months after surgery. Decision regret assessment was completed 6 months after surgery. The prevalence of depression and decision regret was determined by age group. Change in depression over time was compared between age groups using a linear-effects model. Variables potentially associated with moderate to severe depression and decision regret were analyzed using a logistic regression model.

Results: The study included 274 patients (68 women and 206 men; mean [SD] age, 67.8 [9.5] years). Of these, 105 (38.3%) were 50 to 64 years of age and 169 (61.7%) were 65 years or older. The rate of preoperative moderate to severe depression was 9.6% (21 of 219), with no difference between younger and older adult cohorts. For both age groups, depression scores increased in the postoperative period from baseline to 6 months. At 12 months, there was a difference in depression scores between the younger and older adult cohort (4.8 [4.6] vs 3.1 [3.6]). A higher preoperative Fried Frailty Index score (odds ratio, 2.58 [95% CI, 1.63-4.06]) was associated with preoperative moderate to severe depression. For all patients, the mean Decision Regret Scale score was 18.2 (range, 0-95), and 26.7% of patients (48 of 180) had moderate to severe regret. There was no difference in Decision Regret Scale scores between younger and older patients. Preoperative depression but not frailty is associated with postoperative moderate to severe decision regret (odds ratio, 1.17 [95% CI, 1.06-1.28]).

Conclusions and relevance: In this cohort study, there was no difference based on age in the prevalence of moderate to severe depression or decision regret. A higher preoperative frailty score was associated with depression but not decision regret. Preoperative depression was the only factor associated with moderate to severe decision regret on multivariate analysis. Understanding the prevalence of and factors associated with moderate to severe depression and decision regret may aid in identifying patients who would benefit from more extensive preoperative counseling and preoperative and postoperative multispecialty assessment and treatment.

Abstract
Background: Increasing evidence suggests that psychological well-being (PWB) is associated with lower disease and mortality risk, and may be enhanced with relatively low-cost interventions. Yet, dissemination of these interventions remains limited, in part because insufficient attention has been paid to distinct PWB dimensions, which may impact physical health outcomes differently.

Methods: This essay first reviews the empirical evidence regarding differential relationships between all-cause mortality and multiple dimensions of PWB (e.g., life purpose, mastery, positive affect, life satisfaction, optimism). Then, individual-level positive psychology interventions aimed at increasing PWB and tested in randomized-controlled trials are reviewed as these allow for easy implementation and potentially broad outreach to improve population well-being, in concert with efforts targeting other established social determinants of health.

Results: Several PWB dimensions relate to mortality, with varying strength of evidence. Many of positive psychology trials indicate small-to-moderate improvements in PWB; rigorous institution-level interventions are comparatively few, but preliminary results suggest benefits as well. Examples of existing health policies geared towards the improvement of population well-being are also presented. Future avenues of well-being epidemiological and intervention research, as well as policy implications, are discussed.

Conclusions: Although research in the fields of behavioral and psychosomatic medicine, as well as health psychology have substantially contributed to the science of PWB, this body of work has been somewhat overlooked by the public health community. Yet, the growing interest in documenting well-being, in addition to examining its determinants and consequences at a population level may provoke a shift in perspective. To cultivate optimal well-being-mental, physical, social, and spiritual-consideration of a broader set of well-being measures, rigorous studies, and interventions that can be disseminated is critically needed.

Abstract
Background: Cancer patients experience anxiety and depression after diagnosis and during treatment. A wide range of psychological interventions have been proposed to alleviate distress, but the evidence about the perioperative effectiveness of such interventions is not clear. This systematic review examined the effect of preoperative psychological interventions or prehabilitation on the postoperative outcomes of patients undergoing surgery for cancer.

Methods: A systematic review of the published data was performed using Embase, Medline, and PsycInfo for the period from 1946 to February 2014. A total of 951 publications (case series, single case reports, and reviews) were found. Only seven of these studies included patients undergoing an operation for cancer and a preoperative psychological intervention.

Results: Six of the seven studies were randomized controlled trials. Four were conducted with patients who had breast cancer (n = 356). The other studies included patients with gynecologic cancer (n = 30), colorectal cancer (n = 60), and prostate cancer (n = 159). Assessment of the studies showed four to be of good quality, two to be of moderate quality, and one to be of poor quality. Interventions did not affect traditional surgical outcomes (e.g., length of hospital stay, complications, analgesia use, or mortality) but positively affected patients' immunologic function. However, psychological interventions appeared to have an impact on patients' reported outcome measures including psychological outcomes, quality of life, and somatic symptoms.

Conclusion: Available data suggested that preoperative psychological prehabilitation may have a role for cancer patients undergoing surgery. Further evidence is needed to evaluate its role.

Abstract
A maladaptive response to surgical stress might lead to postoperative complications. A multidisciplinary approach aimed at controlling the surgical stress response may reduce procedural complications and improve patients' quality of life in the short and long term. Several studies suggest that psychological interventions may interact with the pathophysiology of surgical stress response, potentially influencing wound repair, innate and adaptive immunity, inflammation, perception of pain, and patients' mood. The aim of this systematic review is to summarise the effects of perioperative psychological interventions on surgical pain and/or anxiety in adult patients scheduled for elective general abdominal and/or urologic surgery.We conducted a systematic review of controlled clinical trials and observational studies involving psychological interventions for adult patients scheduled for elective general abdominal and/or urologic surgery. Only studies reporting pain and/or anxiety among outcome measures were included in the systematic review. The following psychological interventions were considered: (1) relaxation techniques, (2) cognitive-behavioural therapies, (3) mindfulness, (4) narrative medicine, (5) hypnosis and (6) coping strategies.We examined 2174 papers. Among these, 9 studies were considered eligible for inclusion in this systematic review (1126 patients cumulatively): 8 are randomised controlled trials and 1 is an observational prospective pre/post study.Psychological characteristics widely influence the pathophysiological mechanisms underlying the neuroendocrine and inflammatory response to surgical stress, potentially interfering with surgical outcomes. Psychological interventions are technically feasible and realistically applicable perioperatively during abdominal and/or urologic surgery; they influence the pathophysiological mechanisms underlying maladaptive surgical stress response and might have positive effects on patients' surgical outcomes, such as pain and anxiety.

Abstract
Posttraumatic stress disorder (PTSD) is an anxiety disorder that develops after exposure to a traumatic event and is characterized by symptoms of reexperiencing, emotional numbing, persistent arousal, and avoidance. Approximately 6.8% of the people in the United States will be diagnosed with PTSD at some point in their lives. The presence of PTSD in a surgical patient can be important because PTSD is associated with the use of psychoactive medications, risky health behaviors, cardiovascular comorbidities, depression, chronic pain, and cognitive dysfunction, all of which may influence the risk of perioperative morbidity and mortality. In addition, patients with PTSD are anxious around unfamiliar people and in unfamiliar environments. The purposes of this journal course are to provide anesthetists with a working knowledge of the symptoms, treatments, and comorbidities associated with PTSD and to suggest ways of interacting with patients with the disorder that increase trust and decrease the risk of evoking posttraumatic symptoms in the perioperative environment.
