RESUMEN

AIM: Prehabilitation for colorectal cancer has focused on exercise-based interventions that are typically designed by clinicians; however, no research has yet been patient-oriented. The aim of this feasibility study was to test a web-based multimodal prehabilitation intervention (known as PREP prehab) consisting of four components (physical activity, diet, smoking cessation, psychological support) co-designed with five patient partners. METHOD: A longitudinal, two-armed (website without or with coaching support) feasibility study of 33 patients scheduled for colorectal surgery 2 weeks or more from consent (January-September 2021) in the province of British Columbia, Canada. Descriptive statistics analysed a health-related quality of life questionnaire (EQ5D-5L) at baseline (n = 25) and 3 months postsurgery (n = 21), and a follow-up patient satisfaction survey to determine the acceptability, practicality, demand for and potential efficacy in improving overall health. RESULTS: Patients had a mean age of 52 years (SD 14 years), 52% were female and they had a mean body mass index of 25 kg m-2 (SD 3.8 kg m-2). Only six patients received a Subjective Global Assessment for being at risk for malnutrition, with three classified as 'severely/moderately' malnourished. The majority (86%) of patients intended to use the prehabilitation website, and nearly three-quarters (71%) visited the website while waiting for surgery. The majority (76%) reported that information, tools and resources provided appropriate support, and 76% indicated they would recommend the PREP prehab programme. About three-quarters (76%) reported setting goals for lifestyle modification: 86% set healthy eating goals, 81% aimed to stay active and 57% sought to reduce stress once a week or more. No patients contacted the team to obtain health coaching, despite broad interest (71%) in receiving active support and 14% reporting they received 'active support'. CONCLUSION: This web-based multimodal prehabilitation programme was acceptable, practical and well-received by all colorectal surgery patients who viewed the patient-oriented multimodal website. The feasibility of providing active health coaching support requires further investigation.

RESUMEN

OBJECTIVE: We recently found that the risk of diagnosed non-affective psychotic disorder between the ages of 13 and 19 was lower for immigrant adolescents compared to those without a personal or parental migration history in British Columbia (BC), Canada. In the current study, we further examined the risk for migrants compared to non-migrants by region of origin and immigrant generation (first vs. second), adjusting for several demographic factors and migration class. METHODS: Administrative data were used to construct a cohort of individuals born 1990-98 and residing in South-Western BC (N = 193,400). Cases were identified by either one hospitalization or two outpatient physician visits with a primary diagnosis of a non-affective psychotic disorder. Poisson regression was used to estimate incidence rate ratios (IRR) of a diagnosed non-affective psychotic disorder by region of origin among first- and second-generation migrants compared to non-migrants, adjusting for sex, birth year, neighbourhood income and low family income. RESULTS: Risk of diagnosed non-affective psychotic disorder was lower among first-generation migrants from East Asia (IRR = 0.34[95% CI: 0.25-0.46]), South-Asia (IRR = 0.47[95% CI: 0.25-0.89]) and South-East Asia (IRR = 0.55[95% CI: 0.32-0.93]) and second-generation migrants from East Asia (IRR = 0.49[95% CI: 0.35-0.69]) and South Asia (IRR = 0.52[95% CI: 0.37-0.73]), compared to non-migrants. Adjusting for migration class attenuated but did not fully explain variation in risk by region among first-generation migrants. No groups exhibited a significantly elevated risk of the diagnosed non-affective psychotic disorder compared to non-migrants. CONCLUSION: Findings from this study underline the complexity of the association between migration and psychotic disorders. Future research should investigate why certain groups of migrants are less likely to be diagnosed and whether there are specific sub-groups that face an elevated risk.

RESUMEN

PURPOSE: Evidence from systematic reviews suggests that adult immigrants living in areas of higher immigrant density (areas with a higher proportion of foreign-born residents) tend to experience fewer mental health problems-likely through less discrimination, greater access to culturally/linguistically appropriate services, and greater social support. Less is known about how such contexts are associated with mental health during childhood-a key period in the onset and development of many mental health challenges. This study examined associations between neighbourhood immigrant density and youth mental health conditions in British Columbia (BC; Canada). METHODS: Census-derived neighbourhood characteristics were linked to medical records for youth present in ten of BC's largest school districts from age 5 through 19 over the study period (1995-2016; n = 138,090). Occurrence of physician assessed diagnoses of mood and/or anxiety disorders, attention deficit hyperactivity disorder (ADHD), and conduct disorder was inferred through International Classification of Diseases (ICD) diagnostic codes in universal public health insurance records. Multi-level logistic regression was used to model associations between neighbourhood characteristics and odds of diagnoses for each condition; models were stratified by generation status (first-generation: foreign-born; second-generation: Canadian-born to a foreign-born parent; non-immigrant). RESULTS: Higher neighbourhood immigrant density was associated with lower odds of disorders among first-generation immigrant youth (e.g., adjusted odds of mood-anxiety disorders for those in neighbourhoods with the highest immigrant density were 0.67 times lower (95% CI: 0.49, 0.92) than those in neighbourhoods with the lowest immigrant density). Such protective associations generally extended to second-generation and non-immigrant youth, but were-for some disorders-stronger for first-generation than second-generation or non-immigrant youth. CONCLUSIONS: Findings suggest there may be protective mechanisms associated with higher neighbourhood immigrant density for mental health conditions in immigrant and non-immigrant youth. It is important that future work examines potential pathways by which contextual factors impact immigrant and non-immigrant youth mental health.

RESUMEN

OBJECTIVES: To estimate the diagnosed incidence of non-affective psychotic disorder between the ages of 13 and 19 years in South-Western British Columbia (BC) and to examine variation in risk by sex, family and neighbourhood income, family migration background, parent mental health contact and birth year. METHODS: Linked individual-level administrative data were used to construct a cohort of individuals born in 1990-1998 and residing in South-Western BC (n = 193,400). Cases were identified by either one hospitalization or two outpatient physician visits within 2 years with a primary diagnosis of a non-affective psychotic disorder (ICD-10: F20-29, ICD-9: 295, 297, 298). We estimated cumulative incidence, annual cumulative incidence and incidence rate between the ages of 13 and 19 years, and conducted Cox proportional hazards regression to estimate associations between sociodemographic factors and risk over the study period. RESULTS: We found that 0.64% of females and 0.88% of males were diagnosed with a non-affective psychotic disorder between the ages of 13 and 19 years, with increasing risk observed over the age range, especially amongst males. Incidence rate over the entire study period was 106 per 100,000 person-years for females and 145 per 100,000 person-years for males. Risk of diagnosis was elevated amongst those in low-income families and neighbourhoods, those with a parent who had a health service contact for a mental disorder, and more recent birth cohorts. Risk was reduced amongst children of immigrants compared to children of non-migrants. CONCLUSIONS: Findings from this study provide important information for health service planning in South-Western BC. Future work should examine whether variations in diagnosed incidence is driven by differences in health service engagement or reflect genuine differences in risk.

RESUMEN

BACKGROUND: Research findings on the association between outpatient service use and emergency department (ED) visits for mental and substance use disorders (MSUDs) are mixed and may differ by disorder type. METHODS: We used population-based linked administrative data in British Columbia, Canada to examine associations between outpatient primary care and psychiatry service use and ED visits among people ages 15 and older, comparing across people treated for three disorder categories: common mental disorders (MDs) (depressive, anxiety, and/or post-traumatic stress disorders), serious MDs (schizophrenia spectrum and/or bipolar disorders), and substance use disorders (SUDs) in 2016/7. We used hurdle models to examine the association between outpatient service use and odds of any ED visit for MSUDs as well count of ED visits for MSUDs, stratified by cohort in 2017/8. RESULTS: Having had one or more MSUD-related primary care visit was associated with lower odds of any ED visit among people treated for common MDs and SUDs but not people treated for serious MDs. Continuity of primary care was associated with slightly lower ED use in all cohorts. One or more outpatient psychiatrist visits was associated with lower odds of ED visits among people treated for serious MDs and SUDs, but not among people with common MDs. CONCLUSION: Findings highlight the importance of expanded access to outpatient specialist mental health services, particularly for people with serious MDs and SUDs, and collaborative models that can support primary care providers treating people with MSUDs.

RESUMEN

BACKGROUND: The online Tuberculin Skin Test/Interferon Gamma Release Assay (TST/IGRA) Interpreter V3.0 (TSTin3D), a tool for estimating the risk of active tuberculosis (TB) in individuals with latent TB infection (LTBI), has been in use for more than a decade, but its predictive performance has never been evaluated. METHODS: People with a positive TST or IGRA result from 1985 to 2015 were identified using a health data linkage that involved migrants to British Columbia, Canada. Comorbid conditions at the time of LTBI testing were identified from physician claims, hospitalizations, vital statistics, outpatient prescriptions, and kidney and HIV databases. The risk of developing active TB within 2 and 5 years was estimated using TSTin3D. The discrimination and calibration of these estimates were evaluated. RESULTS: A total of 37 163 individuals met study inclusion criteria; 10.4% were tested by IGRA. Generally, the TSTin3D algorithm assigned higher risks to demographic and clinical groups known to have higher active TB risks. Concordance estimates ranged from 0.66 to 0.68 in 2- and 5-year time frames. Comparing predicted to observed counts suggests that TSTin3D overestimates active TB risks and that overestimation increases over time (with relative bias of 3% and 12% in 2- and 5-year periods, respectively). Calibration plots also suggest that overestimation increases toward the upper end of the risk spectrum. CONCLUSIONS: TSTin3D can discriminate adequately between people who developed and did not develop active TB in this linked database of migrants with predominately positive skin tests. Further work is needed to improve TSTin3D's calibration.

RESUMEN

OBJECTIVE: To examine the association between usual place of primary care and mental health consultation among those with self-reported mood or anxiety disorders. We also describe access to mental health services among people who are recent immigrants, longer-term immigrants, and nonimmigrants and determine whether the association with place of primary care differs by immigration group. METHODS: We used data from the Canadian Community Health Survey (2015 to 2016) to identify a representative sample of individuals with self-reported mood or anxiety disorders. We used logistic regression, with models stratified by immigration group (recent, longer-term, nonimmigrant), to examine the association between usual place of primary care and receiving a mental health consultation in the previous 12 months. RESULTS: Higher percentages of recent and longer-term immigrants see a doctor in solo practice, and a higher percentage of recent immigrants use walk-in clinics as a usual place of care. Compared with people whose usual place of care was a community health center or interdisciplinary team, adjusted odds of a mental health consultation were significantly lower for people whose usual place of care was a solo practice doctor's office (AOR = 0.71; 95% CI, 0.62 to 0.82), a walk-in clinic (AOR = 0.75; 95% CI, 0.66 to 0.85), outpatient clinic/other place (AOR = 0.72 95% CI, 0.59 to 0.88), and lowest among people reporting no usual place other than the emergency room (AOR = 0.59; 95% CI, 0.51 to 0.67). Differences in access to mental health consultations by usual place of primary care were greatest among immigrants, especially recent immigrants. CONCLUSIONS: People with mood or anxiety disorders who have access to team-based primary care are more likely to report mental health consultations, and this is especially true for immigrants. Expanded access to team-based primary health care may help reduce barriers to mental health services, especially among immigrants.

RESUMEN

PURPOSE: (1) To determine whether healthy humans can distinguish between the intensity and unpleasantness of exertional dyspnoea; (2) to evaluate the reliability of qualitative dyspnoea descriptors during exercise; and (3) to assess the reliability of the Multidimensional Dyspnoea Profile (MDP) METHODS: Forty-four healthy participants (24M:20F, 25 ± 5 years) completed maximal incremental cycling tests on three visits. During visit 1, participants rated the intensity and unpleasantness of dyspnoea simultaneously throughout exercise using the modified 0-10 category-ratio Borg scale. On visits 2 and 3, participants rated either the intensity or unpleasantness of dyspnoea alone at the same measurement times as visit 1. On all visits, participants selected qualitative descriptors throughout all exercise intensities from a list of 4, selected relevant qualitative descriptors from a list of 15 at peak exercise, and completed the MDP. RESULTS: Participants rated their dyspnoea intensity significantly higher for a given minute ventilation ([Formula: see text]) compared to dyspnoea unpleasantness (dyspnoea-[Formula: see text] slope: 0.08 ± 0.02 vs. 0.07 ± 0.03 Borg 0-10/L min-1, p < 0.001) during visit 1. The onset of intensity ratings occurred at a significantly lower work rate compared to unpleasantness ratings measured on the same exercise test (52 ± 41 vs. 91 ± 53 watts, p < 0.001). Dyspnoea intensity and unpleasantness remained significantly different for a given ventilation even when measured independently on separate exercise tests (p < 0.05). There was good-to-excellent reliability (ICC > 0.60) for the use of qualitative dyspnoea descriptors and the MDP to measure dyspnoea at peak exercise. CONCLUSION: Exercise-induced dyspnoea in healthy adults can differ in the sensory and affective dimensions, and can be measured reliably using qualitative descriptors and the MDP.

RESUMEN

Many adults with single-ventricle congenital heart disease who have undergone a Fontan procedure have abnormal pulmonary function resembling restrictive lung disease. Whether this contributes to ventilatory limitations and increased dyspnea has not been comprehensively studied. We recruited 17 Fontan participants and 17 healthy age- and sex-matched sedentary controls. All participants underwent complete pulmonary function testing followed by a symptom-limited incremental cardiopulmonary cycle exercise test with detailed assessments of dyspnea and operating lung volumes. Fontan participants and controls were well matched for age, sex, body mass index, height, and self-reported physical activity levels (all P > 0.05), although Fontan participants had markedly reduced cardiorespiratory fitness and peak work rates ( P < 0.001). Fontan participants had lower values for most pulmonary function measurements relative to controls with 65% of Fontan participants showing evidence of a restrictive ventilatory defect. Relative to controls, Fontan participants had significantly higher breathing frequency, end-inspiratory lung volume (% total lung capacity), ventilatory inefficiency (high ventilatory equivalent for CO2), and dyspnea intensity ratings at standardized absolute submaximal work rates. There were no between-group differences in qualitative descriptors of dyspnea. The restrictive ventilatory defect in Fontan participants likely contributes to their increased breathing frequency and end-inspiratory lung volume during exercise. This abnormal ventilatory response coupled with greater ventilatory inefficiency may explain the increased dyspnea intensity ratings in those with a Fontan circulation. Interventions that enhance the ventilatory response to exercise in Fontan patients may help optimize exercise rehabilitation interventions, resulting in improved exercise tolerance and exertional symptoms. NEW & NOTEWORTHY This is the first study to comprehensively characterize both ventilatory and sensory responses to exercise in adults that have undergone the Fontan procedure. The majority of Fontan participants had a restrictive ventilatory defect. Compared with well-matched controls, Fontan participants had increased breathing frequency, end-inspiratory lung volume, and ventilatory inefficiency. These abnormal ventilatory responses likely form the mechanistic basis for the increased dyspnea intensity ratings observed in our Fontan participants during exercise.

RESUMEN

Background: Quetiapine is effective in treating depressive symptoms in major depressive disorder and bipolar disorder, but the mechanisms underlying its antidepressants effects are unknown. Norquetiapine, a metabolite of quetiapine, has high affinity for norepinephrine transporter, which might account for its therapeutic efficacy. Methods: In this study, we used positron emission tomography with (S,S)-[11C]O-methyl reboxetine to estimate norepinephrine transporter density and assess the relationship between norepinephrine transporter occupancy by quetiapine XR and improvement in depression in patients with major depressive disorder (n=5) and bipolar disorder (n=5). After the baseline positron emission tomography scan, patients were treated with quetiapine XR with a target dose of 150 mg in major depressive disorder and 300 mg in bipolar disorder. Patients had a second positron emission tomography scan at the end of week 2 and a final scan at week 7. Results: Norepinephrine transporter density was significantly lower in locus ceruleus in patients compared with healthy subjects. Further, there was a significant positive correlation between quetiapine XR dose and norepinephrine transporter occupancy in locus ceruleus at week 2. The norepinephrine transporter occupancy at week 2 in hypothalamus but not in other regions predicted improvement in depression as reflected by reduction in MADRS scores from baseline to week 7. The estimated dose of quetiapine XR associated with 50% norepinephrine transporter occupancy in hypothalamus at week 2 was 256 mg and the estimated plasma levels of norquetiapine to achieve 50% norepinephrine transporter occupancy was 36.8 µg/L. Conclusion: These data provide preliminary support for the hypothesis that norepinephrine transporter occupancy by norquetiapine may be a contributor to the antidepressant effects of quetiapine.

RESUMEN

OBJECTIVE: Prognostication bias, in which a clinician predicts a negative outcome and terminates resuscitation (TR) thereby ensuring a poor outcome, is a rarely identified limitation of out-of-hospital cardiac arrest (OHCA) research. We sought to estimate the number of deaths due to intra-arrest prognostication in a cohort of OHCA's, and use this data to estimate the incremental benefit of continuing resuscitation. METHODS: This study examined a cohort of consecutive non-traumatic EMS-treated OHCAs from a provincial ambulance service, between 2007 and 2011 inclusive. We used Cox and logistic regression modeling, adjusting for Utstein covariates, to estimate the probability of ROSC, survival, and favorable neurological outcomes as a function of resuscitation time, and applied these models to estimate the number of missed survivors in those who had TR (prior to 20, 30, or 40 minutes). We determined the time juncture at which (1) the likelihood of survival fell below 1%, and (2) the proportion of survivors who had achieved ROSC exceeded 99%. RESULTS: Of 5674 adult EMS-treated cases, 46% achieved ROSC, and 12% survived. The median time of TR was 27.0 minutes (IQR 19.0-35.0). Continuing resuscitation until 40 minutes yielded an estimated 17 additional survivors (95% CI 13-21), 10 (95% CI 7-13) with favorable neurological outcomes. The probability of survival of those in refractory arrest decreased below 1% at 28 minutes (95% CI 24-30 minutes). At 36 minutes (95% CI 34-38 minutes) >99% of survivors had achieved ROSC. CONCLUSION: We identified possible deaths due to intra-arrest prognostication. Resuscitation should be continued for a minimum of 30 minutes in all patients, however for those with initial shockable rhythms 40 minutes appears to be warranted. Interventional trials and observational studies should standardize or adjust for duration of resuscitation prior to TR.

RESUMEN

BACKGROUND: Patients with anorexia nervosa exhibit abnormal myocardial repolarization and are susceptible to sudden cardiac death. Exercise testing is useful in unmasking QT prolongation in disorders associated with abnormal repolarization. We characterized QT adaptation during exercise in anorexia. METHODS AND RESULTS: Sixty-one adolescent female patients with anorexia nervosa and 45 age- and sex-matched healthy volunteers performed symptom-limited cycle ergometry during 12-lead ECG monitoring. Changes in the QT interval during exercise were measured, and QT/RR-interval slopes were determined by using mixed-effects regression modeling. Patients had significantly lower body mass index than controls; however, resting heart rates and QT/QTc intervals were similar at baseline. Patients had shorter exercise times (13.7±4.5 versus 20.6±4.5 minutes; P<0.001) and lower peak heart rates (159±20 versus 184±9 beats/min; P<0.001). The mean QTc intervals were longer at peak exercise in patients (442±29 versus 422±19 ms; P<0.001). During submaximal exertion at comparable heart rates (114±6 versus 115±11 beats/min; P=0.54), the QTc interval had prolonged significantly more in patients than controls (37±28 versus 24±25 ms; P<0.016). The RR/QT slope, best described by a curvilinear relationship, was more gradual in patients than in controls (13.4; 95% confidence interval, 12.8-13.9 versus 15.8; 95% confidence interval, 15.3-16.4 ms QT change per 10% change in RR interval; P<0.001) and steepest in patients within the highest body mass index tertile versus the lowest (13.9; 95% confidence interval, 12.9-14.9 versus 12.3; 95% confidence interval, 11.3-13.3; P=0.026). CONCLUSIONS: Despite the absence of manifest QT prolongation, adolescent anorexic females have impaired repolarization reserve in comparison with healthy controls. Further study may identify impaired QT dynamics as a risk factor for arrhythmias in anorexia nervosa.

RESUMEN

OBJECTIVES: The use of physician incentives to improve health care, in general, has been extensively studied but its value in mental health care has rarely been demonstrated. In this study the population-level impact of physician incentives on mental health care was estimated using indicators for receipt of counseling/psychotherapy (CP); antidepressant therapy (AT); minimally adequate counseling/psychotherapy; and minimally adequate antidepressant therapy. The incentives' impacts on overall continuity of care and of mental health care were also examined. MATERIALS AND METHODS: Monthly cohorts of individuals diagnosed with major depression were identified between January 2005 and December 2012 and their use of mental health services tracked for 12 months following initial diagnosis. Linked health administrative data were used to ascertain cases and measure health service use. Pre-post changes associated with the introduction of physician incentives were estimated using segmented regression analyses, after adjusting for seasonal variation. RESULTS: Physician incentives reversed the downward and upward trends in CP and AT. Five years postintervention, the estimated impacts in percentage points for CP, AT, minimally adequate counseling/psychotherapy, and minimally adequate antidepressant therapy were +3.28 [95% confidence interval (CI), 2.05-4.52], -4.47 (95% CI, -6.06 to -2.87), +1.77 (95% CI, 0.94-2.59), and -2.24 (95% CI, -4.04 to -0.45). Postintervention, the downward trends in continuity of care failed to reverse, but were disrupted, netting estimated impacts of +7.53 (95% CI, 4.54-10.53) and +4.37 (95% CI, 2.64-6.09) for continuity of care and of mental health care. CONCLUSIONS: The impact of physician incentives on mental health care was modest at best. Other policy interventions are needed to close existing gaps in mental health care.

RESUMEN

OBJECTIVES: To characterize patterns of sedentary behavior and physical activity in older adults recovering from hip fracture and to determine characteristics associated with activity. METHODS: Community-dwelling, Canadian adults (65 years+) who sustained hip fracture wore an accelerometer at the waist for seven days and provided information on quality of life, falls self-efficacy, cognitive functioning, and mobility. RESULTS: There were 53 older adults (mean age [SD] 79.5 [7.8] years) enrolled in the study; 49 had valid data and demonstrated high levels of sedentary time (median [p10, p90] 591.3 [482.2, 707.2] minutes/day), low levels of light activity (186.6 [72.6, 293.7]), and MVPA (2 [0.1, 27.6]), as well as few daily steps (2467.7 [617.1, 6820.4]). Regression analyses showed that age, gender, gait speed, and time since fracture were associated with outcomes. CONCLUSIONS: Older adults have long periods of sedentary time with minimal activity. Results are a call to action to encourage people to sit less and move more.

RESUMEN

Effective management of end stage renal disease for individuals undergoing hemodialysis (HD) requires the acquisition of self-care abilities, which have been shown to improve outcomes. Studies have indicated that educational interventions improve self-care abilities in patients with chronic kidney failure. A self-care coaching intervention was designed to bridge this gap. To evaluate, we utilized a pre-test/post-test quasi-experimental design using the Self Care for Adults on Dialysis (SCAD) tool. This was administered prior to, four months, and one year after the intervention. Results demonstrated improvement in self-care related to vascular access and fluid management, both significant aspects of being HD-dependent.

RESUMEN

OBJECTIVES: The purpose of this study was to evaluate the effect of a research training program on clinicians' knowledge, attitudes, and practices related to research and evidence-based practice (EBP). BACKGROUND: EBP has been shown to improve patient care and outcomes. Innovative approaches are needed to overcome individual and organizational barriers to EBP. METHODS: Mixed-methods design was used to evaluate a research training intervention with point-of-care clinicians in a Canadian urban health organization. Participants completed the Knowledge, Attitudes, and Practice Survey over 3 timepoints. Focus groups and interviews were also conducted. RESULTS: Statistically significant improvement in research knowledge and ability was demonstrated. Participants and administrators identified benefits of the training program, including the impact on EBP. CONCLUSIONS: Providing research training opportunities to point-of-care clinicians is a promising strategy for healthcare organizations seeking to promote EBP, empower clinicians, and showcase excellence in clinical research.

RESUMEN

Public health interventions implemented during the COVID-19 pandemic may exacerbate anxiety symptoms for many. We conducted this study to better understand the role of leisure activity in promoting mental wellness during times of social isolation and reduced access to recreation facilities and mental health support services. We analyzed nationally representative survey data collected by Statistics Canada as part of the Canadian Perspectives Survey Series (CPSS) during May 4-10 (CPSS 2) and July 20 to 26, 2020 (CPSS 4). Data related to leisure activity and anxiety symptoms as measured by a score of more than 10 on the General Anxiety Disorder scale were examined using descriptive and log-binomial regression analyses. Survey sampling weights were applied in all analyses, and regression results were adjusted for sociodemographic characteristics. Exercise and communication with friends and loved ones were the most frequently reported leisure activity. Prevalence of moderate to severe anxiety symptoms reported by participants was lower in CPSS 4 compared to CPSS 2. Results of adjusted log-binomial regression analyses revealed lower prevalence of moderate to severe anxiety symptoms in those who engaged in exercise and communication, while those who meditated exhibited higher prevalence. In conclusion, leisure activities, such as exercise and communication with loved ones, can promote mental wellness. Future research should clarify the role of meditation for mental wellness promotion during periods of social isolation.

RESUMEN

BACKGROUND: The rising trend of providing palliative care to residents in Canadian long-term care facilities places additional demands on care staff, increasing their risk of burnout. Interventions and strategies to alleviate burnout are needed to reduce its impact on quality of patient care and overall functioning of healthcare organizations. AIM: To examine the feasibility of implementing online modules with the primary goal of determining recruitment and retention rates, completion time and satisfaction with the modules. A secondary goal was to describe changes in burnout and related symptoms associated with completing the modules. SETTING: This single-arm, nonrandomized feasibility study was conducted in five long-term care sites of a publicly-funded healthcare organization in Vancouver, British Columbia, Canada. Eligible participants were clinical staff who worked at least 1 day per month. RESULTS: A total of 103 study participants consented to participate, 31 (30.1%) of whom were lost to follow-up. Of the remaining 72 participants, 64 (88.9%) completed the modules and all questionnaires. Most participants completed the modules in an hour (89%) and found them easy to understand (98%), engaging (84%), and useful (89%). Mean scores on burnout and secondary traumatic stress decreased by .9 (95% CI: .1-1.8; d = .3) and 1.4 (95% CI: .4-2.4; d = .4), respectively; mean scores on compassion satisfaction were virtually unchanged. CONCLUSIONS: Modules that teach strategies to reduce burnout among staff in long-term care are feasible to deliver and have the potential to reduce burnout and related symptoms. Randomized controlled trials are needed to assess effectiveness and longer-term impact.
