Both New and Chronic Potentially Inappropriate Medications Continued at Hospital Discharge Are Associated With Increased Risk of Adverse Events.

ABSTRACT: BACKGROUND:Admission to hospital provides the opportunity to review patient medications; however, the extent to which the safety of drug regimens changes after hospitalization is unclear. OBJECTIVE:To estimate the number of potentially inappropriate medications (PIMs) prescribed to patients at hospital discharge and their association with the risk of adverse events 30?days after discharge. DESIGN:Prospective cohort study. SETTING:Tertiary care hospitals within the McGill University Health Centre Network in Montreal, Quebec, Canada. PARTICIPANTS:Patients from internal medicine, cardiac, and thoracic surgery, aged 65?years and older, admitted between October 2014 and November 2016. MEASURES:Abstracted chart data were linked to provincial health databases. PIMs were identified using AGS (American Geriatrics Society) Beers Criteria®, STOPP, and Choosing Wisely statements. Multivariable logistic regression and Cox models were used to assess the association between PIMs and adverse events. RESULTS:Of 2,402 included patients, 1,381 (57%) were male; median age was 76?years (interquartile range [IQR] = 70-82?years); and eight discharge medications were prescribed (IQR = 2-8). A total of 1,576 (66%) patients were prescribed at least one PIM at discharge; 1,176 (49%) continued a PIM from prior to admission, and 755 (31%) were prescribed at least one new PIM. In the 30?days after discharge, 218 (9%) experienced an adverse drug event (ADE) and 862 (36%) visited the emergency department (ED), were rehospitalized, or died. After adjustment, each additional new PIM and continued community PIM were respectively associated with a 21% (odds ratio [OR] =?1.21; 95% confidence interval [CI] =?1.01-1.45) and a 10% (OR = 1.10; 95% CI = 1.01-1.21) increased odds of ADEs. They were also respectively associated with a 13% (hazard ratio [HR] =?1.13; 95% CI = 1.03-1.26) and a 5% (HR = 1.05; 95% CI = 1.00-1.10) increased risk of ED visits, rehospitalization, and death. CONCLUSIONS:Two in three hospitalized patients were prescribed a PIM at discharge, and increasing numbers of PIMs were associated with an increased risk of ADEs and all-cause adverse events. Improving hospital prescribing practices may reduce the frequency of PIMs and associated adverse events. J Am Geriatr Soc 68:1184-1192, 2020.

Project description:Background/objectivesTo examine the prevalence of potentially inappropriate medication (PIM) prescribing and its association with healthcare utilization and related expenditures utilizing nationally representative data from the United States.DesignRetrospective cohort study.SettingThe 2011-2015 Medical Expenditure Panel Survey (MEPS).ParticipantsCommunity-dwelling sample of U.S. adults aged 65 and older during the first round of each MEPS cycle.MeasurementsA qualified definition operationalized from the 2019 American Geriatrics Society Beers Criteria® was used to estimate the prevalence of PIM prescribing over the study period. Negative binomial models were assembled to examine associations between PIM exposure and healthcare utilization including hospitalizations, emergency department (ED) visits, and outpatient provider visits. Generalized linear models with the log link function and gamma distribution were used to analyze associations between PIM exposure and healthcare expenditures. Sensitivity analyses were conducted utilizing inverse probability treatment weighting using propensity scores for being prescribed a PIM.ResultsThe period prevalence of PIM prescribing over the 5-year sample was 34.4%. PIM prescribing was positively associated with hospitalizations (adjusted incidence rate ratio [aIRR] = 1.17; 95 confidence interval [CI] = 1.08-1.26; P < .001), ED visits (aIRR = 1.26; 95% CI = 1.17-1.35; P < .001), and outpatient provider visits (aIRR = 1.18; 95% CI = 1.14-1.21; P < .001). PIM exposure was associated with higher marginal costs within outpatient visits ($116; 95% CI = $105-$243; P < .001), prescription medications ($128; 95% CI = $72-$199; P < .001), and total healthcare expenditures ($458; 95% CI = $295-$664; P < .001). Similar results were found in our propensity score analyses.ConclusionPIMs continue to be prescribed at a high rate among older adults in the United States. Our results suggest that receipt of PIMs is associated with higher rates of healthcare utilization and increased costs across the healthcare continuum. Further work is needed to implement evidence-based deprescribing interventions that may in turn reduce unnecessary healthcare utilization.

Project description:BackgroundAlthough opioids are initiated on hospital discharge in millions of older adults each year, there are no studies examining patient- and prescribing-related risk factors for opioid-related adverse drug events (ADEs) after hospital discharge among medical patients.MethodsA retrospective cohort study of a national sample of Medicare beneficiaries aged 65 years and older, hospitalized for a medical reason, with at least one claim for an opioid within 2 days of hospital discharge. We excluded patients receiving hospice care and patients admitted from or discharged to a facility. We used administrative billing codes and medication claims to define potential opioid-related ADEs within 30 days of hospital discharge, and competing risks regression to identify risk factors for these events.ResultsAmong 22,879 medical hospitalizations (median age 74, 36.9% female) with an opioid claim within 2 days of hospital discharge, a potential opioid-related ADE occurred in 1604 (7.0%). Independent risk factors included age of 80 years and older (HR 1.18, 95% CI 1.05-1.33); clinical conditions, including kidney disease (HR 1.22, 95% CI 1.08-1.37), dementia/delirium (HR 1.38, 95% CI 1.22-1.56), anxiety disorder (HR 1.20, 95% CI 1.06-1.36), opioid use disorder (HR 1.20, 95% CI 1.03-1.39), intestinal disorders (HR 1.31, 95% CI 1.15-1.49), pancreaticobiliary disorders (HR 1.32, 95% CI 1.09-1.61), and musculoskeletal and nervous system injuries (HR 1.35, 95% CI 1.17-1.54); red flags for opioid misuse (HR 1.37, 95% CI 1.04-1.80); opioid use in the 30 days before hospitalization (HR 1.20, 95% CI 1.08-1.34); and prescription of long-acting opioids (HR 1.34, 95% CI 1.06-1.70).ConclusionsPotential opioid-related ADEs occurred within 30 days of hospital discharge in 7.0% of older adults discharged from a medical hospitalization with an opioid prescription. Identified risk factors can be used to inform physician decision-making, conversations with older adults about risk, and development and targeting of harm reduction strategies.
