A week long "pep" talk - initial and 2-3-year longitudinal data on the Ottawa Psychiatry Enrichment Program (OPEP).

BACKGROUND: Recruitment to psychiatry as a career has been challenging in Canada and abroad despite the known shortage and increasing burden of psychiatric issues globally. Deterrents to choosing psychiatry as a career include its negative stigma and paucity of knowledge about the field. The study goal was to evaluate the Ottawa Psychiatry Enrichment Program (OPEP), a one-week extracurricular program about psychiatry as a career for 1st and 2nd year medical students. We hypothesized OPEP would improve students' attitudes towards psychiatry, and positive changes would be sustained 2-3 years later following their residency match. We hypothesized there would be a high recruitment of OPEP attendees to psychiatry programs. METHODS: 1st and 2nd year medical students from Canada applied to OPEP. Attendees completed the Attitudes Towards Psychiatry Questionnaire (ATP-30) at three times: before OPEP (PreOPEP), after OPEP (PostOPEP) and after their Canadian Residency Matching Service (CaRMs) match 2-3 years later. OPEP ATP-30 scores were compared to third-year student ATP-30 scores before and after their psychiatry rotation. Data were analysed using Friedman non-parametric ANOVA and post hoc testing by either Wilcoxon rank sum test, Wilcoxon matched pairs signed rank test, or parametric Welch independent t-test as appropriate. Effect sizes of group mean differences were calculated using Cohen's "d". RESULTS: Between 2017-2018, 29/53 Canadian applicants were selected for OPEP. 100%, 93.1% and 75.8% of OPEP students completed the PreOPEP, PostOPEP, and CaRMs ATP-30 surveys respectively. 43% of OPEP attendees matched to psychiatry. PostOPEP ATP-30 scores (mean = 133, median = 137, SD = 10.6) were significantly higher than PreOPEP ATP-30 (mean score = 121, median = 122, SD = 9.3, p < 0.001) and CaRMS ATP-30 (mean = 126, median = 127, SD = 12.3, p < 0.02) scores. OPEP effect size on ATP-30 scores was large (d = 1.2) but decreased 2-3 years later (p = 0.078, d = 0.44). 97/202 students completed the ATP-30 before and after their psychiatry rotation (clerkship). Clerkship effect size on improvement in ATP-30 was moderate (d = 0.39). There was a non-significant difference between OPEP CaRMS ATP-30 and post clerkship ATP-30 scores (median 127 vs 121, p = 0.056). CONCLUSIONS: OPEP ameliorated attitudes toward Psychiatry, but improvement deteriorated longitudinally. Strategies for program design, and innovations to boost/retain improvements during clerkship years are discussed.

Autonomic Modulation of Cardiac Activity Across Levels of Sleep Depth in Individuals With Depression and Sleep Complaints.

OBJECTIVE: We assessed mean heart rate (HR) and HR variability (HRV) across wake, rapid eye movement (REM) sleep, and non-REM (NREM) sleep, and across varying levels of NREM sleep depth in individuals with depression and sleep complaints. METHODS: Retrospective polysomnographic data were obtained for 25 individuals diagnosed as having depression (84% female; mean age = 33.8 ± 12.2 years) and 31 mentally healthy controls (58.1% female; mean age = 37.2 ± 12.4 years). All were free of psychotropic and cardiovascular medication, cardiovascular disease, and sleep-related breathing disorders. HR and time-domain HRV parameters were computed on 30-second electrocardiography segments and averaged across the night for each stage of sleep and wake. RESULTS: Compared with the control group, the depression group had higher HR across wake, REM, and all levels of NREM depth (F(1,51) = 6.3, p = .015). Significant group by sleep stage interactions were found for HRV parameters: SD of normal-to-normal intervals (SDNN; F(2.1,107.7) = 4.4, p = .014) and root mean square differences of successive R-R intervals (RMSSD; F(2.2,113.5) = 3.2, p = .041). No significant group difference was found for SDNN or RMSSD during wake (all, p ≥ .32). However, compared with the control group, the depression group had significantly lower SDNN in REM (p = .040) and all NREM stages (all p ≤ .045), and lower RMSSD during NREM 2 (p = .033) and NREM 3 (p = .034). CONCLUSIONS: This study suggests that the abnormalities in autonomic cardiac regulation associated with depression and sleep problems are more prominent during sleep, especially NREM sleep, than during wake. This may be due to abnormalities in parasympathetic modulation of cardiac activity.

Using heart rate profiles during sleep as a biomarker of depression.

BACKGROUND: Abnormalities in heart rate during sleep linked to impaired neuro-cardiac modulation may provide new information about physiological sleep signatures of depression. This study assessed the validity of an algorithm using patterns of heart rate changes during sleep to discriminate between individuals with depression and healthy controls. METHODS: A heart rate profiling algorithm was modeled using machine-learning based on 1203 polysomnograms from individuals with depression referred to a sleep clinic for the assessment of sleep abnormalities, including insomnia, excessive daytime fatigue, and sleep-related breathing disturbances (n = 664) and mentally healthy controls (n = 529). The final algorithm was tested on a distinct sample (n = 174) to categorize each individual as depressed or not depressed. The resulting categorizations were compared to medical record diagnoses. RESULTS: The algorithm had an overall classification accuracy of 79.9% [sensitivity: 82.8, 95% CI (0.73-0.89), specificity: 77.0, 95% CI (0.67-0.85)]. The algorithm remained highly sensitive across subgroups stratified by age, sex, depression severity, comorbid psychiatric illness, cardiovascular disease, and smoking status. CONCLUSIONS: Sleep-derived heart rate patterns could act as an objective biomarker of depression, at least when it co-occurs with sleep disturbances, and may serve as a complimentary objective diagnostic tool. These findings highlight the extent to which some autonomic functions are impaired in individuals with depression, which warrants further investigation about potential underlying mechanisms.

Geriatric Psychiatry Teaching in Canadian Medical Schools: a Cross-Sectional Study.

OBJECTIVE: With a growing geriatric population and limited geriatric psychiatrists in Canada, it is crucial to provide sufficient training in geriatric psychiatry during medical school. The authors examined how geriatric psychiatry education is delivered in Canadian medical schools during clerkship. Factors that could be associated with increased geriatric psychiatry teaching in medical schools were examined. The authors were also interested in comparing Canadian to US findings. METHODS: A cross-sectional survey was distributed to the psychiatry medical education representatives attending the Canadian Organization of Undergraduate Psychiatry Educators (COUPE) semi-annual meeting in September 2017. RESULTS: All 17 (100%) medical schools completed the survey. Fifteen of the 17 schools (88%) have geriatric psychiatry-specific learning objectives. Five schools (29%) offer a clinical component in geriatric psychiatry. One school has an award for clerks (6%), and no awards exist for faculty. The number of lecture hours in geriatric psychiatry is moderately correlated with the presence of a geriatric component to psychiatry clerkship (Spearman's rho = 0.67, p = 0.003) and the length of the geriatric portion of clerkship (Spearman's rho = 0.64, p value = 0.006). Lecture hours are also moderately correlated with the presence of a geriatric fellowship (Spearman's rho = 0.68, p value = 0.003). CONCLUSIONS: Geriatric psychiatry clerkship education is inconsistent in Canada. There is virtually no recognition of excellence in teaching or undergraduate performance in this area in clerkship. Geriatric psychiatry may receive more frequent attention in Canadian medical schools than in US medical schools.

Factors affecting recruitment into psychiatry: a canadian experience.

OBJECTIVE: There is a projected shortage of psychiatrists in Canada in forthcoming years. This study assessed factors in medical school education that are associated with students selecting psychiatry first and matching as a discipline. METHOD: The Canadian Organization of Undergraduate Psychiatry Educators (COUPE) conducted telephone interviews and sent e-mail questionnaires to the 17 medical schools across Canada; all schools provided data for 2012. Relevant data were obtained from the Canadian Resident Matching Service. Statistics were performed using v12 STATA program, and significance was set at a p value of <0.05. RESULTS: Medical student enrollment ranged from 54 to 266 students (mean = 158 ± 16). Of these students, 4.9 ± 0.6 % ranked psychiatry as their first choice for residency. Final match results yielded similar numbers at 5.0 ± 0.6 %. Ten out of 17 programs filled all psychiatry residency positions, whereas the remaining 7 programs had vacancy rates from 5 to 100 % (mean = 43.4 ± 15.1 %). Medical students were exposed to an average of 2.8 ± 0.5 pre-clerkship psychiatry weeks and 6.2 ± 0.3 clerkship weeks. Linear regression analysis demonstrated that the percentage of graduating medical students entering a psychiatry residency program could be predicted from the number of weeks of pre-clerkship exposure (p = 0.01; R(2) = 0.36) but not from the number of clerkship weeks (p = 0.74). CONCLUSIONS: This study indicates that the duration of pre-clerkship exposure to psychiatry predicts the number of students selecting psychiatry as their first choice as a discipline. Thus, increasing the duration of pre-clerkship exposure may increase the enrollment of medical students into psychiatry.

Creation of a shortened version of the Sleep Disorders Questionnaire (SDQ).

The 176-item Sleep Disorders Questionnaire (SDQ) was initially developed using canonical discriminant function analysis on 4 groups of sleep disorder patients, but it was never studied by factor analysis in its entirety. Several authors have criticized 2 of its subscales as being confounded with each other, and its narcolepsy scale as substantially over-diagnosing narcolepsy. This study describes its first exploratory factor analysis (EFA), the intent of which was to reassess item membership on the 4 existing subscales and to derive new scales to improve differential diagnosis between patient groups. It was also hoped that EFA could reduce the total number of questions, to increase speed of completion. The EFA was performed on the anonymized SDQ results from a retrospective review of the charts of 2131 persons from 7 sleep disorders clinics and research centers. Factors were assessed via scree plots and eigenvalues. The EFA identified four main factors: insomnia, daytime sleepiness, substance use, and sleep-disordered breathing. The insomnia factor had 3 subfactors: psychological symptoms of insomnia, subjective description of insomnia, and insomnia due to periodic limb movements. The sleepiness factor had two subfactors: daytime sleepiness and neurological symptoms of narcolepsy. The novel substance use factor was homogeneous, as was the sleep-disordered breathing factor. Importantly, the EFA reassigned items from the original SDQ's NAR, PSY, and PLM subscales to five of the new subscales. The Sleep Apnea (SA) subscale emerged mostly unchanged. The 7 resulting factors comprised only 66 items of the original 176-item SDQ. These results have allowed the creation of a new shorter questionnaire, to be called the SDQ-2. External validation of the SDQ-2 is currently underway. It will likely prove to be a superior differential diagnostic instrument for sleep disorders clinics, compared to the original SDQ.

Measuring Clinical Preparedness After Residency Training: Development of a New Instrument.

BACKGROUND AND OBJECTIVES: Research on preparedness for independent clinical practice typically uses surveys of residents and program directors near graduation, which can be affected by several biases. We developed a novel approach to assess new graduates more objectively using physician and staff member assessors 3 months after graduates started their first job. METHODS: We conducted a literature review and key informant interviews with physicians from varying practice types and geographic regions in the United States to identify features that indicate a lack of preparedness for independent clinical practice. We then held a Clinical Preparedness Measurement Summit, engaging measurement experts and family medicine education leaders, to build consensus on key indicators of readiness for independent clinical practice and survey development strategies. The 2015 entrustable professional activities for family medicine end-of-residency training provided the framework for assessment of clinical preparedness by physician assessors. Sixteen published variables assessing interpersonal communication skills and processes of care delivery were identified for staff assessors. We assessed frequencies and compared survey findings between physician and staff assessors in 2016 to assist with survey validation. RESULTS: The assessment of frequencies demonstrated a range of responses, supporting the instrument's ability to distinguish readiness for independent practice of recent graduate hires. No statistical differences occurred between the physician and staff assessors for the same physician they were evaluating, indicating internal consistency. CONCLUSIONS: To learn about the possible impact of length of training, we developed a novel approach to assess preparedness for independent clinical practice of family medicine residency graduates.

Postresidency Practice Setting and Clinical Care Features According to 3 Versus 4 Years of Training in Family Medicine: A Length of Training Pilot Study.

BACKGROUND AND OBJECTIVES: Factors associated with physician practice choice include residency location, training experiences, and financial incentives. How length of training affects practice setting and clinical care features postgraduation is unknown. METHODS: In this Length of Training Pilot (LoTP) study, we surveyed 366 graduates of 3-year (3YR) and 434 graduates of 4-year (4YR) programs 1 year after completion of training between 2013 and 2021. Variables assessed included reasons for practice setting choice, practice type, location, practice and community size, specialty mix, and clinical care delivery features (eg, integrated behavioral health, risk stratified care management). We compared different length of training models using χ2 or Fisher's exact tests for categorical variables and independent samples, and t test (unequal variances) for continuous variables. RESULTS: Response rates ranged from 50% to 88% for 3YR graduates and 68% to 95% for 4YR graduates. Scope of practice was a predominant reason for graduates choosing their eventual practice, and salary was a less likely reason for those completing 4 years versus 3 years of training (scope, 72% vs 55%, P=.001; salary, 15% vs 22%, P=.028). Community size, practice size, practice type, specialty mix, and practice in a federally designated underserved site did not differ between the two groups. We found no differences in patient-centered medical home features when comparing the practices of 3YR to 4YR graduates. CONCLUSIONS: Training length did not affect practice setting or practice features for graduates of LoTP programs. Future LoTP analyses will examine how length of training affects scope of practice and clinical preparedness, which may elucidate other elements associated with practice choice.

Vestibular symptoms are related to the proportion of REM sleep in people with sleep complaints: A preliminary report.

OBJECTIVE/BACKGROUND: Though sleep problems (apnea, insomnia) and related daytime symptoms (fatigue, anxiety, depression) have been associated with vestibular problems (falls, dizziness), it is not well known which particular sleep features relate to vestibular problems. We thus assessed symptoms of vestibular problems in patients visiting a sleep clinic and evaluated how they were associated with objective sleep parameters derived from polysomnography and relevant daytime symptoms. PATIENTS/METHODS: The polysomnography data of thirty-one patients (61% female, between 20 and 79 years of age) who were referred for clinical sleep assessment was collated with subjective measures of symptoms linked to vestibular problems (rated on the Situational Characteristics Questionnaire), as well as fatigue, anxiety and depression symptoms. Multiple linear regression was used to identify factors associated with vestibular symptoms, including analyses adjusted for age, sex, medication use and total sleep time. RESULTS: A higher percentage of REM sleep and more severe anxiety symptoms were independently associated with more severe vestibular symptoms, which survived adjusted analyses. Other sleep stages, as well as as sleep efficiency, apnea-hypopnea index and oxygen saturation were not significantly related to vestibular symptoms. CONCLUSIONS: These results point at vestibular symptoms as possible important and overlooked correlates of variations in sleep architecture in individuals with sleep complaints. Though replication is needed to confirm findings from this limited sample, the results highlight the importance of assessing vestibular symptoms in people with sleep complaints. In particular, further investigations will need to address the potential implication of REM sleep for vestibular functions and the directionality of this relation.

Financing the Fourth Year: Experiences of Required 4-Year Family Medicine Residency Programs.

The optimal length of family medicine training has been debated since the specialty's inception. Currently there are four residency programs in the United States that require 4 years of training for all residents through participation in the Accreditation Council for Graduate Medical Education Length of Training Pilot. Financing the additional year of training has been perceived as a barrier to broader dissemination of this educational innovation. Utilizing varied approaches, the family medicine residency programs at Middlesex Health, Greater Lawrence Health Center, Oregon Health and Science University, and MidMichigan Medical Center all demonstrated successful implementation of a required 4-year curricular model. Total resident complement increased in all programs, and the number of residents per class increased in half of the programs. All programs maintained or improved their contribution margins to their sponsoring institutions through additional revenue generation from sources including endowment funding, family medicine center professional fees, institutional collaborations, and Health Resources and Services Administration Teaching Health Center funding. Operating expense per resident remained stable or decreased. These findings demonstrate that extension of training in family medicine to 4 years is financially feasible, and can be funded through a variety of models.

Selective serotonin reuptake inhibitor use is associated with worse sleep-related breathing disturbances in individuals with depressive disorders and sleep complaints: a retrospective study.

STUDY OBJECTIVES: The effects of serotonergic agents on respiration neuromodulation may vary according to differences in the serotonin system, such as those linked to depression. This study investigated how sleep-related respiratory disturbances relate to depression and the use of medications commonly prescribed for depression. METHODS: Retrospective polysomnography was collated for all 363 individuals who met selection criteria out of 2,528 consecutive individuals referred to a specialized sleep clinic (Ottawa, Canada) between 2006 and 2016. The apnea-hypopnea index (AHI), oxygen saturation nadir, and oxygen desaturation index during REM and NREM sleep were analyzed using mixed analyses of covariance comparing 3 main groups: (1) medicated individuals with depressive disorders (antidepressant group; subdivided into the selective serotonin reuptake inhibitor and norepinephrine-dopamine reuptake inhibitor subgroups), (2) non-medicated individuals with depressive disorders (non-medicated group), and (3) mentally healthy control patients (control group). RESULTS: Individuals with depressive disorders (on antidepressants or not) had significantly higher AHIs compared to control patients (both P ≤ .007). The antidepressant group had a lower NREM sleep oxygen saturation nadir and a higher NREM sleep oxygen desaturation index than the control and non-medicated groups (all P ≤ .009). Within individuals with depressive disorders, independent of depression severity, the selective serotonin reuptake inhibitor group had a lower oxygen saturation nadir and a higher oxygen desaturation index during NREM sleep than the norepinephrine-dopamine reuptake inhibitor (both P ≤ .045) and non-medicated groups (both P < .001) and a higher NREM sleep AHI than the non-medicated group (P = .014). CONCLUSIONS: These findings suggest that the use of selective serotonin reuptake inhibitors may be associated with impaired breathing and worse nocturnal oxygen saturation in individuals with depressive disorders and sleep complaints, but this needs to be confirmed by prospective studies.

Sleep in psychiatric disorders: where are we now?

Although the precise function of sleep is unknown, decades of research strongly implicate that sleep has a vital role in central nervous system (CNS) restoration, memory consolidation, and affect regulation. Slow-wave sleep (SWS) and rapid eye movement (REM) sleep have been of significant interest to psychiatrists; SWS because of its putative role in CNS energy recuperation and cognitive function, and REM sleep because of its suggested involvement in memory, mood regulation, and possible emotional adaptation. With the advent of the polysomnogram, researchers are now beginning to understand some of the consequences of disrupted sleep and sleep deprivation in psychiatric disorders. The same neurochemistry that controls the sleep-wake cycle has also been implicated in the pathophysiology of numerous psychiatric disorders. Thus it is no surprise that several psychiatric disorders have prominent sleep symptoms. This review will summarize normal sleep architecture, and then examine sleep abnormalities and comorbid sleep disorders seen in schizophrenia, as well as anxiety, cognitive, and substance abuse disorders.

Sleep pathologies in depression and the clinical utility of polysomnography.

Abnormal sleep accompanies many psychiatric conditions, but has long been recognized as a particularly conspicuous feature of affective disorders. More than a mere epiphenomenon, the powerful link between sleep and mood regulation is most dramatically demonstrated by the high efficacy of sleep deprivation in alleviating depression. Indeed, the sleep abnormalities that accompany depression may be due to the same neuropathologies that are responsible for its mood and cognitive symptoms. This powerful link between sleep and mood regulation makes polysomnography (PSG) a useful window into the underlying pathophysiology of depression, yet it is underused, particularly in clinical diagnosis. Recent depression research has emphasized the importance of establishing biologically relevant subtypes of depression with treatment specificity and prognostic value. PSG measures, among other biological markers, may be of importance in establishing these subtypes. Two subtypes of depression that appear to have robust biological differences, the melancholic and atypical subtypes, have recently been shown to have different sleep profiles that can aid in differential diagnosis. Further, routine use of PSG in the workup of a depressed patient would minimize the chances of misdiagnosis in those suffering from primary sleep disorders such as sleep apnea, which can present secondary mood symptoms resembling depression. Increased use of PSG in clinical psychiatric practice would enlarge the body of data available for defining new depressive subtypes in the future. It would also serve an immediate purpose in the separation of atypical, compared with melancholic, depression, and the differential diagnosis of depression from primary sleep disorders.

Smiles for Life: A National Oral Health Curriculum for Family Medicine. A model for curriculum development by STFM groups.

The Society of Teachers of Family Medicine Group on Oral Health released Smiles for Life: A National Oral Health Curriculum for Family Medicine in October 2005 to address a need for high-quality residency and medical school curricula in an area of documented physician knowledge deficit. This article describes the background, planning, fund-raising, development, dissemination, and impact of the curriculum. Lessons learned, particularly in the areas of long-distance collaboration, fund-raising, and marketing are reviewed with a goal of serving as a model for future curriculum development efforts.

Effect of atypical antipsychotics on body weight in geriatric psychiatric inpatients.

BACKGROUND: Studies suggest that antipsychotic-induced weight gain is not a great concern in the elderly population. This study investigated the weight change in elderly patients with various treatment duration and antipsychotics. Part 1 of the study was to determine whether atypical antipsychotics induced weight change in elderly patients. Part 2 was to determine whether certain atypical antipsychotics induced more weight change in elderly patients. METHODS: In Part 1, a retrospective chart review was done on 115 geriatric inpatients. After exclusion, patients were divided into four groups: control (n = 17), new treatment (n = 18), long-term treatment (n = 13), and medication switch groups (n = 8). In Part 2, a retrospective medication review was performed on 169 geriatric inpatients. After exclusion, patients were divided into three groups: aripiprazole (n = 18), olanzapine (n = 49), and risperidone (n = 57). Body weights were obtained at two different time points. RESULTS: No significant difference in weight change was observed among the control (1.5 kg), new treatment (0.8 kg), long-term treatment (-0.3 kg), and medication switch (1.9 kg) groups. No significant difference in weight change was observed between patients with and without dementia (0.8 and 1.1 kg, respectively). The weight change in the aripiprazole group (-2.0 kg; -2.30% from baseline) was significantly different from the weight change in the olanzapine group (0.7 kg; 1.87% from baseline; p < 0.05), but not from the risperidone group (-0.4 kg; -0.45% from baseline). Clinically significant weight gain (>7% increase in body weight) occurred in 14.3% of the olanzapine patients, a percentage significantly higher than the 3.5% in the risperidone group. CONCLUSION: Although atypical antipsychotics were generally weight neutral in the geriatric population, aripiprazole and olanzapine were associated with significant weight loss and weight gain, respectively.

The State of Sleep Medicine Education in North American Psychiatry Residency Training Programs in 2013: Chief Resident's Perspective.

OBJECTIVE: To assess the current state of sleep medicine educational resources and training offered by North American psychiatry residency programs. METHODS: In June 2013, a 9-item peer-reviewed Sleep Medicine Training Survey was administered to 39 chief residents of psychiatry residency training programs during a meeting in New York. RESULTS: Thirty-four percent of the participating programs offered an elective rotation in sleep medicine. A variety of innovative approaches for teaching sleep medicine were noted. The majority of the chief residents felt comfortable screening patients for obstructive sleep apnea (72%), half felt comfortable screening for restless legs syndrome (53%), and fewer than half were comfortable screening for other sleep disorders (47%). CONCLUSIONS: This is the first report in the last decade to provide any analysis of current sleep medicine training in North American psychiatry residency training programs. These data indicate that sleep medicine education in psychiatry residency programs is possibly in decline.

Impact of Residency Training Redesign on Residents' Clinical Knowledge.

BACKGROUND AND OBJECTIVES: The In-training Examination (ITE) is a frequently used method to evaluate family medicine residents' clinical knowledge. We compared family medicine ITE scores among residents who trained in the 14 programs that participated in the Preparing the Personal Physician for Practice (P4) Project to national averages over time, and according to educational innovations. METHODS: The ITE scores of 802 consenting P4 residents who trained in 2007 through 2011 were obtained from the American Board of Family Medicine. The primary analysis involved comparing scores within each academic year (2007 through 2011), according to program year (PGY) for P4 residents to all residents nationally. A secondary analysis compared ITE scores among residents in programs that experimented with length of training and compared scores among residents in programs that offered individualized education options with those that did not. RESULTS: Release of ITE scores was consented to by 95.5% of residents for this study. Scores of P4 residents were higher compared to national scores in each year. For example, in 2011, the mean P4 score for PGY1 was 401.2, compared to the national average of 386. For PGY2, the mean P4 score was 443.1, compared to the national average of 427, and for PGY3, the mean P4 score was 477.0, compared to the national PGY3 score of 456. Scores of residents in programs that experimented with length of training were similar to those in programs that did not. Scores were also similar between residents in programs with and without individualized education options. CONCLUSIONS: Family medicine residency programs undergoing substantial educational changes, including experiments in length of training and individualized education, did not appear to experience a negative effect on resident's clinical knowledge, as measured by ITE scores. Further research is needed to study the effect of a wide range of residency training innovations on ITE scores over time.

Sleep apnea as a possible factor contributing to aggression in sex offenders.

Sleep disorders, such as obstructive sleep apnea (OSA), are often unrecognized and undertreated. A disruption in normal sleep may be associated with increased irritability and aggression. To elucidate further the impact of OSA on hostility of forensic patients, we performed a retrospective chart review of 10 consecutive outpatient sex offenders who were diagnosed with OSA and treated with continuous positive airway pressure (CPAP). The Buss-Perry Aggression Questionnaire was compared pre- and posttreatment. Following treatment, the total Buss-Perry score was significantly lower, with lower scores on the anger, physical aggression, hostility, and verbal aggression subscales. These results suggest that in sex offenders suffering from OSA, aggression and hostility may be significantly reduced through CPAP treatment. Further investigation is required to investigate if reducing aggression and hostility in this manner impacts recidivism and overall functioning.
