This chapter examines associations between psychotropic medications and mortality in long-term care home (LTCH) settings. We report new findings with census-level data from all new admissions to long-term care homes in the province of Ontario, Canada (i.e., 20,414 new residents). The data include three linked sets that indicate mortality during the financial years 2010–2011 and 2011–2012. One dataset, the Resident Assessment Instrument 2.0 (RAI 2.0), provides information on demographics, functional capability, clinical conditions, clinical diagnoses, mortality risk, and psychotropic medications. The latter include antipsychotics, antidepressants, analgesics, anxiolytics, and hypnotics. Administration of the RAI 2.0 occurs at resident intake, at quarterly intervals and annually. New analyses reported here examine predictors of daily and pro re nata (i.e., PRN or “as needed”) prescriptions of psychotropic medications. However, the most important analyses concern predictors of mortality within intervals of up to 90 days from the final RAI 2.0 assessment. After control for confounding variables, the findings indicate (1) attenuated mortality with daily prescription of frequently prescribed psychotropics (i.e., antipsychotics, antidepressants, and analgesics), (2) augmented mortality with PRN prescriptions for each type of psychotropic medication, and (3) evidence that PRN prescribing overturns beneficial effects of daily prescriptions, whereas the latter reduces the deleterious effects of PRN prescribing.

This chapter examines mortality in long-term care home (LTCH) residents as associated with the use antipsychotic medication when combined with other psychotropic medications. The data at census-level pertain to all new admissions to long-term care homes (LTCH) in Ontario, Canada, during a given financial year (i.e., over 20,000 LTCH residents). The observations include comprehensive assessment upon admission and at quarterly intervals thereafter for a maximal period of 1-year after the initial assessment. The mortality data derive from three linked databases, with mortality classified as death within 90 days of the final assessment. The findings indicate that combinations of concurrent daily usage of antipsychotic medication with daily usage of other psychotropic medications (particularly antidepressants and analgesics) are associated with relatively low mortality, whereas intermittent usage (e.g. pro re nata; as needed) is associated with relatively high mortality.
