Identification of psychiatric patients with high mortality and low medical utilization: a population-based propensity score-matched analysis.

ABSTRACT: BACKGROUND:The decreased life expectancy and care costs of mental disorders could be enormous. However, research that compares mortality and utilization concurrently across the major category of mental disorders is absent. This study investigated all-cause mortality and medical utilization among patients with and without mental disorders, with an emphasis on identifying the psychiatric category of high mortality and low medical utilization. METHODS:A total of 570,250 individuals identified from the 2002-2013 Taiwan National Health Insurance Reearch Database consistuted 285,125 psychiatric patients and 285,125 non-psychiatric peers through 1:1 dual propensity score matching (PSM). The expenditure survival ratio (ESR) was proposed to indicate potential utilization shortage. The category of mental disorders and 13 covariates were analyzed using the Cox proportional hazard model and general linear model (GLM) through SAS 9.4. RESULTS:PSM analyses indicated that mortality and total medical expenditures per capita were both significantly higher in psychiatric patients than those in non-psychiatric patients (all P <.0.0001). Patients with substance use disorders were reported having the youngest ages at diagnosis and at death, with the highest 25.64 of potential years of life loss (YPLL) and relevant 2904.89 of ESR. Adjusted Cox model and GLM results indicated that, compared with anxiety disorders, affective disorders and substance use disorders were significantly associated with higher mortality (HR?=?1.246 and 1.064, respectively; all P?

Project description:IntroductionMental health and substance use disorder (MHSUD) patients in the emergency department (ED) have been facing increasing lengths of stay due to a shortage of inpatient beds. Previous research indicates mobile crisis outreach (MCO) reduces long ED stays for MHSUD patients. Our objective was to assess the impact of MCO contact on future ED utilization.MethodsWe conducted a retrospective chart review of patients presenting to a large Midwest university ED with an MHSUD chief complaint from 2015-2018. We defined the exposure as those who had MCO contact and any MHSUD-related ED visit within 30 days of MCO contact. The MCO patients were 2:1 propensity score-matched by demographic data and comorbidities matched to patients with no MCO contact. Outcomes were all-cause and psychiatric-specific reasons for return to the ED within one year of the index ED visit. We report descriptive statistics and odds ratios (OR) to describe the difference between the two groups, and hazard ratios (HR) to estimate the risk of return ED visit.ResultsThe final sample included 106 MCO and 196 non-MCO patients. The MCO patients were more likely to be homeless (OR 14.8; 95% confidence interval [CI],1.87, 117), less likely to have adequate family or social support (OR 0.51; 95% CI, 0.31, 0.84), and less likely to have a hospital bed requested for them in the index visit by ED providers (OR 0.50; 95% CI, 0.29, 0.88). For those who returned to the ED, the median time for all-cause return to the ED was 28 days (interquartile range [IQR]: 6-93 days) for the MCO patients and 88 days (IQR: 20-164 days) for non-MCO patients. The risk of all-cause return to the ED was greater among MCO patients (67%) compared to non-MCO patients (49%) (adjusted HR: 1.66; 95% CI, 1.22, 2.27).ConclusionThe MCO patients had less family and social support; however, they were less likely to require hospitalization for each visit, likely due to MCO involvement. Patients with MCO contact presented to the ED more frequently than non-MCO patients, which implies a strong linkage between the ED and MCO in our community. An effective referral to community service from the ED and MCO and collaboration could be the next step to improve healthcare utilization.

Project description:Objectives In Germany, behavioural medical rehabilitation programmes have been implemented for patients with musculoskeletal disorders and additional mental health comorbidity. The aim of this cohort study is to assess the relative effectiveness of behavioural medical rehabilitation under real-life conditions. Design Participants received either a common or behavioural medical rehabilitation programme. Propensity score matching was used to provide balanced samples of both groups (German Clinical Trials Register: DRKS00016404). Participants A total of 360 patients treated in behavioural medical rehabilitation were compared with 360 matched controls. The mean age of study participants was approximately 53.5 years (standard deviation (SD)=7.0 years) and 74.0% were women. Results No significant and clinical meaningful differences were found in return to work, applications for disability pension, and the number of patients receiving social security benefits in the year after rehabilitation. However, participants in behavioural medical rehabilitation reported better self-rated work ability, physical functioning and self-management skills, and decreased pain disability and fear-avoidance beliefs 10 months after rehabilitation. Standardized effect sizes were between 0.13 and 0.22. Conclusion Behavioural medical rehabilitation had no clinical meaningful effect on maintaining and restoring work ability. However, behavioural medical rehabilitation affected pain and disease management skills 10 months after completing the rehabilitation programme. LAY ABSTRACT Mental health comorbidity increases the risk for patients with musculoskeletal disorders to receive a disability pension despite participating in a multimodal rehabilitation programme. In Germany, behavioural medical rehabilitation programmes were therefore developed for people who are affected from both musculoskeletal and mental health disorders. These programmes integrate additional psychological treatment into the standard multimodal rehabilitation approach. To test whether these programmes are more effective in enabling a stable return to work and improving self-rated health, this study compared 360 patients treated in behavioural medical rehabilitation with 360 comparable controls treated in conventional medical rehabilitation. The results indicate that participants could benefit more from a behavioural medical rehabilitation programme. Patients did not return to work significantly more often. However, they reported better self-rated work ability, better pain and health-related outcomes, and fewer days with unemployment benefits. In conclusion, more consistent implementation of the programme offers the opportunity to further improve these outcomes.

Project description:ObjectivesWe examined the relationship between dominant sedation strategy, risk of delirium and patient-centred outcomes in adults admitted to intensive care units (ICUs).DesignRetrospective propensity-matched cohort study.SettingMechanically ventilated adults (≥ 18 years) admitted to four Canadian hospital medical/surgical ICUs from 2014 to 2016 in Calgary, Alberta, Canada.Participants2837 mechanically ventilated adults (≥ 18 years) requiring admission to a medical/surgical ICU were evaluated for the relationship between sedation strategy and delirium.InterventionsNone.Primary and secondary outcome measuresThe primary exposure was dominant sedation strategy, defined as the sedative infusion, including midazolam, propofol or fentanyl, with the longest duration before the first delirium assessment. The primary outcome was 'ever delirium' identified using the Intensive Care Delirium Screening Checklist. Secondary outcomes included mortality, length of stay (LOS), ventilation duration and days with delirium. The cohort was analysed in two propensity score (patient characteristics and therapies received) matched cohorts (propofol vs fentanyl and propofol vs midazolam).Results2837 patients (60.7% male; median age 57 years (IQR 43-68)) were considered for propensity matching. In propensity score-matched cohorts(propofol vs midazolam, n=712; propofol vs fentanyl, n=1732), the odds of delirium were significantly higher with midazolam (OR 1.46 (95% CI 1.06 to 2.00)) and fentanyl (OR 1.22 (95% CI 1.00 to 1.48)) compared with propofol dominant sedation strategies. Dominant sedation strategy with midazolam and fentanyl were associated with a longer duration of ventilation compared with propofol. Fentanyl was also associated with increased ICU mortality (OR 1.50, 95% CI 1.07 to 2.12)) ICU and hospital LOS compared with a propofol dominant sedation strategy.ConclusionsWe identified a novel association between fentanyl dominant sedation strategies and an increased risk of delirium, a composite outcome of delirium or death, duration of mechanical ventilation, ICU LOS and hospital LOS. Midazolam dominant sedation strategies were associated with increased delirium risk and mechanical ventilation duration.
