A One-Year Institutional View of Resident Physician Burnout.

OBJECTIVES: This prospective study explores the prevalence, associated characteristics, and trajectory of burnout over one academic year in a multidisciplinary sample of resident physicians using a relatively new burnout survey instrument. METHODS: All residents from a U.S. academic health center (n = 633) were invited to complete the Copenhagen Burnout Inventory (CBI) three times, with 4-month time lags between invitations. A total of 281 (44%) provided complete CBI survey responses at least once, and 43 (7%) did at all three times. Descriptive statistics, cross-sectional analyses, correlations, and multivariable linear regression analyses were computed, as well as repeated measures ANOVAs and paired t tests, as appropriate, for each CBI domain (personal, work, patient-related burnout). RESULTS: About half had CBI scores indicating moderate-to-high levels of personal burnout (49-52%) and work-related burnout (45-49%), whereas patient-related burnout was less common (14-24%). However, patient-related burnout increased significantly from the beginning to the end of the year. Regression analyses indicated patient-related burnout was significantly higher for postgraduate year 1-2 residents compared to PGY 4+ residents, but was not significantly different by gender. Personal and work burnout scores were significantly higher for females. Persistently high burnout was observed in only 6% of respondents. CONCLUSIONS: In this study of resident physicians using the CBI, burnout was prevalent and higher levels of burnout were observed for females on the personal and work burnout domains, while junior residents had higher patient-related burnout. Persistently, high burnout was rare. The CBI demonstrated high reliability, was practical to administer, and produced similar results with existing burnout research.

Adverse childhood experiences and geriatric depression: results from the 2010 BRFSS.

OBJECTIVE: Adverse childhood experiences (ACEs), including physical, sexual, and emotional abuse, have been shown to result in a variety of poor outcomes including depression. The majority of research has examined the impact of such events on adolescents and young adults leaving a dearth of information regarding how these events may affect depressive symptom point prevalence later in life. METHODS: Data from the U.S. CDC's 2010 Behavioral Risk Factor Surveillance Survey (BRFSS) were used to estimate the point prevalence of depression in individuals 60 years of age and greater based on presence or absence of certain ACEs. Depressive symptoms were assessed using eight items from the Patient Health Questionnaire (PHQ). Subjects with a PHQ score of 10 or greater were categorized as depressed. Six different types of ACE were included in the study: parents being physically abusive to each other, being physically harmed by a parent, being sworn at by the parent, being touched sexually by an adult, being forced to sexually touch an adult, and being forced into a sexual encounter. ACEs were categorized as never, single if subject reported it occurring once, or repeated if subject reported multiple episodes. RESULTS: The study sample consisted of 8,051 adults aged 60 years and greater who responded to questions about adverse childhood experiences. The study sample comprised 53% women, 83% Caucasian patients, and had a mean age of 70.4 years. After controlling for age, sex, and race, depression was significantly correlated with repeated ACEs of all types (adjusted odds ratio [AOR] ranging from 2.41 to 9.78, all statistically significant). The only ACE where a single occurrence was significantly associated with late-life depression was forced sexual intercourse (AOR: 2.92, 95% CI: 1.06-8.02). After controlling for all types of abuse in a single model, repeated physical abuse and repeated forced sexual intercourse remained significant (AOR: 2.94, 95% CI: 1.68-5.13; AOR: 3.66, 95% CI: 1.01-13.2, respectively). DISCUSSION: These results indicate a significant association between repeated ACEs and depression in older adults. When controlling for all forms of abuse, repeated physical abuse and forced sexual intercourse are significantly correlated with late-life depression. They emphasize the need to continue developing techniques to help individuals with a history of ACEs in order to decrease their negative effects, not only immediately, but also later in life.

Vitamin D Levels and Sociodemographic and Clinical Correlates in Individuals With Serious Mental Illness Admitted to an Acute Psychiatry Unit.

OBJECTIVE: To describe the prevalence of vitamin D deficiency in psychiatric inpatients with serious mental illness. Associated clinical and sociodemographic factors are also explored. METHOD: Data were collected using a retrospective review of medical records. Eligible subjects were individuals aged ≥ 18 years who were consecutively newly admitted to an adult inpatient teaching unit of a state psychiatric hospital from July 2012 through August 2013. The main outcome measure was prevalence rate of vitamin D deficiency in the target population. Vitamin D deficiency was defined as a level < 20 ng/mL. Psychiatric diagnoses were established using DSM-IV-TR criteria. RESULTS: Of 85 subjects, approximately two-thirds (67%) had a vitamin D level < 20 ng/mL. The mean vitamin D level was 18.4 ng/mL. Among the sociodemographic and clinical factors analyzed, only total serum protein (odds ratio = 0.33; CI, 0.12-0.88; P < .05) was associated with vitamin D deficiency. CONCLUSIONS: The high prevalence of vitamin D deficiency with all the attendant physical and mental health burdens in vulnerable populations such as individuals with serious mental illness requires further large research studies. In the meantime, it seems prudent to institute routine screening for vitamin D deficiency in individuals with mental illness, especially those who are hospitalized.

Cyclic antidepressants and the risk of sudden cardiac death.

BACKGROUND: Tricyclic and other related cyclic antidepressants (TCAs), used frequently for the treatment of depression and several other indications, have cardiovascular effects that may increase the risk of sudden cardiac death. We thus sought to quantify the risk of sudden cardiac death among TCA users, according to dose, as well as among users of selective serotonin reuptake inhibitors (SSRIs). METHODS: We conducted a retrospective cohort study in Tennessee Medicaid, from Jan 1, 1988, through Dec 31, 1993, which included large numbers of antidepressant users and computer files describing medication use and comorbidity. The cohort included 1,282,091 person-years of follow-up for persons aged 15 to 84 years who were not in a nursing home and were free of life-threatening noncardiac illness. This included 58,956 person-years for current use of TCAs alone, 6291 person-years for SSRIs only, and 96,220 person-years for former use. RESULTS: The cohort included 1487 confirmed sudden cardiac deaths occurring in the community. When compared with nonusers of antidepressants, current users of TCAs had a dose-related increase in the risk of sudden cardiac death. Rate ratios increased from 0.97 (95% confidence interval [CI], 0.72-1.29) for doses lower than 100 mg (amitriptyline or its equivalent) to 2.53 (95% CI, 1.04-6.12) for doses of 300 mg or more (P =.03, test for dose-response). The rate ratio for SSRIs was 0.95 (95% CI, 0.42-2.15). There was no evidence that TCA doses lower than 100 mg increased the risk of sudden cardiac death in subgroups defined by pre-existing cardiovascular disease, female sex, age 65 years or older, or use of amitriptyline. CONCLUSIONS: Our data suggest that SSRI antidepressants and TCAs in doses of less than 100 mg (amitriptyline equivalents) did not increase the risk of sudden cardiac death. However, higher doses of TCAs were associated with increased relative risk, which suggests that such doses should be used cautiously, particularly in patients with an elevated baseline risk of sudden death.

P.R.N. (As-needed) orders and exposure of psychiatric inpatients to unnecessary psychotropic medications.

OBJECTIVE: The objective of this study was to evaluate whether the practice of writing standing p.r.n. (as-needed) orders exposes psychiatric inpatients to unnecessary psychotropic medications. METHODS: Medical records for 223 new hospital admissions between July 15 and October 15, 1999, when p.r.n. orders were allowed, and 224 new admissions between November 15, 1999, and February 15, 2000, when p.r.n. orders were not allowed and only "now" orders were permitted, were reviewed from the three acute adult psychiatric units of the Arkansas State Hospital in Little Rock. Data were collected on demographic and clinical characteristics, scheduled and unscheduled psychotropic medications as noted in the medication administration records, use of seclusion and restraint, and incident reports of physical aggression. The mean numbers of unscheduled psychotropic medication doses administered during the two periods were compared. RESULTS: The number of unscheduled psychotropic medications administered decreased from 1,812 in the first period to 976 in the second period (adjusted mean doses per admission, 7.8 to 4.3). The decrease in use of unscheduled medications when standing p.r.n. orders were no longer allowed was not associated with corresponding increases in adverse events: there were fewer incidents of restraint (four compared with eight), fewer incidents of seclusion (41 compared with 48), and fewer incidents of physical aggression (35 compared with 40). In addition, there were no significant changes in the dosages of scheduled psychotropic medications on day 7 of admission, indicating that physicians were not increasing dosages in response to the elimination of p.r.n. orders. CONCLUSIONS: The practice of writing p.r.n. orders may expose psychiatric inpatients to unnecessary psychotropic medications.

Monitoring for metabolic side effects among outpatients with dementia receiving antipsychotics.

OBJECTIVE: This study examined monitoring for metabolic side effects among older outpatients with dementia starting a new antipsychotic. METHODS: In a retrospective cohort analysis of U.S. Department of Veterans Affairs data, monitoring, as recommended by the American Diabetes Association and the American Psychiatric Association, was examined between October 1, 2005, and September 30, 2011. The sample included outpatients aged ≥60 years with dementia but without a psychotic disorder (N=3,903) and outpatients with a psychotic disorder but without dementia (N=5,779) who were prescribed a new antipsychotic. Because dementia patients differed from psychosis patients in all observed patient characteristics, especially age, metabolic monitoring of dementia patients was compared with a propensity score-matched sample of outpatients with psychosis (1,576 matched pairs). RESULTS: At baseline (±30 days from the index prescription), 68% of the matched dementia patients were weighed, compared with 63.7% of the matched psychosis patients (odds ratio [OR]=1.28, 95% confidence interval [CI]=1.03-1.48). Monitoring for glucose or glycosylated hemoglobin (HBA1c) and low-density lipoprotein (LDL) was not significantly different between the groups: glucose or HBA1c, 41% versus 44%; LDL, 24% versus 27%. At three months (±30 days), metabolic monitoring for all three parameters was significantly lower for the dementia group: weight, OR=.86, CI=.75-.99; glucose or HBA1c, OR=.83, CI=.71-.97; and LDL, OR=.69, CI=.57-.85. CONCLUSIONS: Monitoring rates for metabolic side effects were low for both dementia and psychosis groups, with lower rates for dementia patients at follow-up compared with matched psychosis patients. Quality improvement efforts are needed to improve monitoring, especially for patients with dementia.

Misclassification of current benzodiazepine exposure by use of a single baseline measurement and its effects upon studies of injuries.

PURPOSE: Measurement of drug exposure is a major methodologic challenge for pharmacoepidemiologic studies of acute effects of medications taken intermittently. If the effect is plausible only during periods of active drug use, daily (or even more frequent) exposure measurement is optimal. Benzodiazepines, episodically used hypnotics and anxiolytics, impair psychomotor function and some epidemiologic studies have reported users have increased risk of unintentional injuries. However, several prospective cohort studies of this question defined benzodiazepine exposure status from a single baseline measurement, and these have not consistently reported increased risk. We used data from an historical cohort study to demonstrate the extent of misclassification potentially induced by this practice. METHODS: The cohort consisted of 2510 Tennessee nursing home residents 65 years of age or older identified in a prior study of antidepressants and falls. Both baseline users (any in 7 days preceding start of follow-up) and current use (use on a given day of follow-up) of benzodiazepines were determined from facility medication administration records, which record information on drugs given to the resident each day. Falls were ascertained from nursing home incident reports and medical records. The effect of benzodiazepine exposure for each ascertainment method was estimated from incidence rate ratios adjusted for multiple fall risk factors by Poisson regression. RESULTS: The 666 baseline benzodiazepine users had current use on 44.6% (95% CI, 40.2-49.2%) of follow-up person-days; baseline non-users had current use for 3.7% of days (2.8-4.7%). Misclassification increased with length of follow-up and with quintile of fall risk. The adjusted fall incidence rate ratios for the baseline user and current use definitions were 1.02 (95% CI, 0.95-1.10) and 1.44 (1.33-1.56), respectively. CONCLUSION: These findings strongly suggest that to avoid potentially serious misclassification, studies of the acute effects of benzodiazepines and other drugs taken intermittently need to track exposure on a day-by-day basis.
