Antipsychotic Agents - adverse effects
2005
Recently, the FDA issued an advisory stating that atypical antipsychotic medications (such as olanzapine and risperidone) increase mortality among elderly patients. This study compared mortality rates among elderly patients who began using either atypical antipsychotic agents or conventional drugs (such as perphenazine and thioridazine). Conventional agents were associated with a higher rate of death. Thus, elderly patients should not be switched from atypical to conventional agents to reduce the risk of death.
This study compared mortality rates among elderly patients who began using either atypical antipsychotic agents or conventional drugs. Conventional agents were associated with a higher rate of death.
Antipsychotic medications are disproportionately used among elderly persons and are prescribed for more than a quarter of Medicare beneficiaries in nursing homes.

The conditions for which these agents are prescribed include dementia, delirium, psychosis, agitation, and affective disorders, with many of the prescriptions being written for indications that have not been approved by the Food and Drug Administration (FDA).

In addition to increasing use, there have been rapid shifts from first-generation conventional agents (e.g., phenothiazines and butyrophenones) to heavily marketed second-generation atypical agents (e.g., aripiprazole [Abilify], clozapine [Clozaril], olanzapine [Zyprexa], quetiapine [Seroquel], risperidone [Risperdal], and ziprasidone [Geodon]).

Anti-Inflammatory Agents, Non-Steroidal - therapeutic use
2006
Background: Postmarketing observational studies of the safety and effectiveness of prescription medications are critically important but fraught with methodological problems. The data sources available for such research often lack information on indications and other important confounders for the drug exposure under study. Instrumental variable methods have been proposed as a potential approach to control confounding by indication in nonexperimental studies of treatment effects; however, good instruments are hard to find. Methods: We propose an instrument for use in pharmacoepidemiology that is based on a time-varying estimate of the prescribing physician's preference for one drug relative to a competing therapy. The use of this instrument is illustrated in a study comparing the effect of exposure to COX-2 inhibitors with nonselective, nonsteroidal anti-inflammatory medications on gastrointestinal complications. Results: Using conventional multivariable regression adjusting for 17 potential confounders, we found no protective effect due to COX-2 use within 120 days from the initial exposure (risk difference = -0.06 per 100 patients; 95% confidence interval = -0.26 to 0.14). However, the proposed instrumental variable method attributed a protective effect to COX-2 exposure (-1.31 per 100 patients; -2.42 to -0.20) compatible with randomized trial results (-0.65 per 100 patients; -1.08 to -0.22). Conclusions: The instrumental variable method that we have proposed appears to have substantially reduced the bias due to unobserved confounding. However, more work needs to be done to understand the sensitivity of this approach to possible violations of the instrumental variable assumptions.

Participants’ Engagement With and Results From a Web-Based Integrative Population Mental Wellness Program (CHAMindWell) During the COVID-19 Pandemic: Program Evaluation Study
2023
The COVID-19 pandemic involved a prolonged period of collective trauma and stress during which substantial increases in mental health concerns, like depression and anxiety, were observed across the population. In this context, CHAMindWell was developed as a web-based intervention to improve resilience and reduce symptom severity among a public health care system's patient population.
This program evaluation was conducted to explore participants' engagement with and outcomes from CHAMindWell by retrospectively examining demographic information and mental health symptom severity scores throughout program participation.
We examined participants' symptom severity scores from repeated, web-based symptom screenings through Computerized Adaptive Testing for Mental Health (CAT-MH) surveys, and categorized participants into symptom severity-based tiers (tier 1=asymptomatic to mild; tier 2=moderate; and tier 3=severe). Participants were provided tier-based mindfulness resources, treatment recommendations, and referrals. Logistic regressions were conducted to evaluate associations between demographic variables and survey completion. The McNemar exact test and paired sample t tests were performed to evaluate changes in the numbers of participants in tier 1 versus tier 2 or 3 and changes in depression, anxiety, and posttraumatic stress disorder severity scores between baseline and follow-up.
The program enrolled 903 participants (664/903, 73.5% female; 556/903, 61.6% White; 113/903, 12.5% Black; 84/903, 9.3% Asian; 7/903, 0.8% Native; 36/903, 4% other; and 227/903, 25.1% Hispanic) between December 16, 2020, and March 17, 2022. Of those, 623 (69%) completed a baseline CAT-MH survey, and 196 completed at least one follow-up survey 3 to 6 months after baseline. White racial identity was associated with completing baseline CAT-MH (odds ratio [OR] 1.80, 95% CI 1.14-2.84; P=.01). Participants' odds of having symptom severity below the clinical threshold (ie, tier 1) were significantly greater at follow-up (OR 2.60, 95% CI 1.40-5.08; P=.001), and significant reductions were observed across symptom domains over time.
CHAMindWell is associated with reduced severity of mental health symptoms. Future work should aim to address program engagement inequities and attrition and compare the impacts of CHAMindWell to a control condition to better characterize its effects.

Objective: To review evidence on the workplace prevalence and correlates of major depressive episodes, with a particular focus on the National Comorbidity Survey Replication, the most recent national survey to focus on these issues. Method: Nationally representative survey of Diagnostic and Statistical Manual, 4th Revision Mental Disorders. Results: A total of 6.4% of employed National Comorbidity Survey Replication respondents had 12-month major depressive disorder. An additional 1.1% had major depressive episodes due to bipolar disorder or mania-hypomania. Only about half of depressed workers received treatment. Fewer than half of treated workers received care consistent with published treatment guidelines. Conclusions: Depression disease management programs can have a positive return-on-investment from the employer perspective, but only when they are based on best practices. Given the generally low depression treatment quality documented here, treatment quality guarantees are needed before expanding workplace depression screening, outreach, and treatment programs.

Objective: The objective of this study was to explore the acceptability and feasibility of a therapeutic assessment protocol for the Screening and Support of Youth (SASY). SASY provides brief but comprehensive community-based screening and support for diverse youth in the community. Methods: SASY screening evaluates symptoms, functioning and clinical risk. The Kiddie Computerized Adaptive Test was used to evaluate seven different diagnoses and symptom severity. The Weiss Functional Impairment Rating Scale-Self was used to measure functional impairment. Measures were scored according to nationally developed norms. An algorithm was developed to aggregate symptom and function ratings into an overall score for clinical risk. The results are discussed with participants in a motivational interview designed to promote insight, followed by the opportunity for the participant to engage in an online intervention. Protocol changes necessitated by social distancing during the pandemic led to innovative methods including the use of a QR code for recruitment, integration of both online and offline participation, and expansion from in-person recruitment within the schools to virtual engagement with youth throughout the community. The final sample included disproportionately more Black or African American and Hispanic youth as compared to school and community statistics, suggesting that optimization of online and offline methods in research may facilitate the recruitment of diverse populations. Qualitative interviews indicated that the screening and feedback raised youth awareness of their wellbeing and/or distress, its impact on their functioning, and engagement with options for improved wellbeing. Conclusions: The emergence of innovative methods optimizing the advantages of both online and offline methods, developed as a necessity during the pandemic, proved advantageous to the feasibility and acceptability of community-based recruitment of at-risk, minoritized youth.

Objective: There is limited occupational health industry data pertaining to 1) the prevalence of psychological distress in various employee subtypes and 2) risk factors for employee psychological distress. Method: The employees of 58 large public and private sector employers were invited to complete the Kessler 6 (K6) as part of the Health and Performance at Work Questionnaire. A K6 score of ≥13 was chosen to indicate high psychological distress. Results: Data on 60,556 full-time employees indicate that 4.5% of employees have high psychological distress of which only 22% were in current treatment. Occupational risk factors identified include long working hours, sales staff and non-traditional gender roles. Conclusion: High psychological distress is pervasive across all employee subtypes and remains largely untreated. Risk factors identified will guide the targeting of mental health promotion, prevention and screening programs.

The Effects of Chronic Medical Conditions on Work Loss and Work Cutback
2001
Although work performance has become an important outcome in cost-of-illness studies, little is known about the comparative effects of different commonly occurring chronic conditions on work impairment in general population samples. Such data are presented here from a large-scale nationally representative general population survey The data are from the MacArthur Foundation Midlife Development in the United States (MIDUS) survey, a nationally representative telephone-mail survey of 3032 respondents in the age range of 25 to 74 years. The 2074 survey respondents in the age range of 25 to 54 years are the focus of the current report. The data collection included a chronic-conditions checklist and questions about how many days out of the past 30 each respondent was either totally unable to work or perform normal activities because of health problems (work-loss days) or had to cut back on these activities because of health problems (work-cutback days). Regression analysis was used to estimate the effects of conditions on work impairments, controlling for sociodemographics. At least one illness-related work-loss or work-cutback day in the past 30 days was reported by 22.4% of respondents, with a monthly average of 6.7 such days among those with any work impairment. This is equivalent to an annualized national estimate of over 2.5 billion work-impairment days in the age range of the samph. Cancer is associated with by far the highest reported prevalence of any impairment (66.2%) and the highest conditional number of impairment days in the past 30 (16.4 days). Other conditions associated with high odds of any impairment include ulcers, major depression, and panic disorder, whereas other conditions associated with a larg conditional number of impairment days include heart disease and high blood pressure. Comorbidities involving combinations of arthritis, ulcers, mental disorders, and substance dependence are associated with higher impairments than expected on the basis of an additive model. The effects of conditions do not differ systematically across subsamples defined on the basis of age, sex, education, or employment status. The enormous magnitude of the work impairment associated with chronic conditions and the economic advantages of interventions for ill workers that reduce work impairment should be factored into employer cost-benefit calculations of expanding health insurance coverage. Given the enormous work impairment associated with cancer and the fact that the vast majority of employed people who are diagnosed with cancer stay in the workforce through at hast part of their course of treatment, interventions aimed at reducing the workplace costs of this illness should be a priority.

The Science of Psychiatric Measurement
2023
In this article, we compare and contrast mental health measurement based on classical test theory (CTT) with computerized adaptive testing (CAT) based on multidimensional item response theory (MIRT). We show that MIRT-based CAT has numerous advantages over the traditional CTT approach in terms of maximizing the precision of measurement while at the same time decreasing the burden of measurement both for the clinician and patient. We review the literature on CAT for depression, anxiety, mania/hypomania, posttraumatic stress disorder, suicidality psychosis, and substance use disorders. We highlight two interesting applications, one for national prevalence determination, and one for student mental health. Applications to special populations where item-level bias may exist and integration with electronic medical records systems are also discussed.

Antipsychotic Agents - therapeutic use
2007
Public health advisories have warned that the use of atypical antipsychotic medications increases the risk of death among elderly patients. We assessed the short-term mortality in a population-based cohort of elderly people in British Columbia who were prescribed conventional and atypical antipsychotic medications.
We used linked health care utilization data of all BC residents to identify a cohort of people aged 65 years and older who began taking antipsychotic medications between January 1996 and December 2004 and were free of cancer. We compared the 180-day all-cause mortality between residents taking conventional antipsychotic medications and those taking atypical antipsychotic medications.
Of 37 241 elderly people in the study cohort, 12 882 were prescribed a conventional antipsychotic medication and 24 359 an atypical formulation. Within the first 180 days of use, 1822 patients (14.1%) in the conventional drug group died, compared with 2337 (9.6%) in the atypical drug group (mortality ratio 1.47, 95% confidence interval [CI] 1.39-1.56). Multivariable adjustment resulted in a 180-day mortality ratio of 1.32 (1.23-1.42). In comparison with risperidone, haloperidol was associated with the greatest increase in mortality (mortality ratio 2.14, 95% CI 1.86-2.45) and loxapine the lowest (mortality ratio 1.29, 95% CI 1.19-1.40). The greatest increase in mortality occurred among people taking higher (above median) doses of conventional antipsychotic medications (mortality ratio 1.67, 95% CI 1.50-1.86) and during the first 40 days after the start of drug therapy (mortality ratio 1.60, 95% CI 1.42-1.80). Results were confirmed in propensity score analyses and instrumental variable estimation, minimizing residual confounding.
Among elderly patients, the risk of death associated with conventional antipsychotic medications is comparable to and possibly greater than the risk of death associated with atypical antipsychotic medications. Until further evidence is available, physicians should consider all antipsychotic medications to be equally risky in elderly patients.

Associations between chronic conditions and work performance (absenteeism, presenteeism, and critical incidents) were studied in reservation agents, customer service representatives, executives, and railroad engineers. Conditions and work performance were assessed with the World Health Organization's Health and Work Performance Questionnaire. Analysis of covariance was used to estimate associations. More work performance was lost from presenteeism than absenteeism. However, chronic conditions more consistently had negative impacts on absenteeism than presenteeism. Conditions with significant effects included arthritis, asthma, chronic obstructive pulmonary disease—emphysema, depression, and chronic headaches. Arthritis had the largest aggregate effect on absenteeism—presenteeism. Only depression affected both absenteeism—presenteeism and critical incidents. Some chronic conditions have substantial workplace effects. Disease management programs for these conditions might have a positive return on investment (ROI). Health and productivity tracking surveys are needed to evaluate ROI and provide quality assurance.
