Article Abstract

Introduction: Previous studies have shown that longer-term prescriptions could improve medication adherence of patients with chronic diseases. However, no evidence demonstrated the impact of a longer supply duration on patients' clinical outcomes. The objective is to estimate the association between longer-term prescriptions with patients' clinical outcomes.

Methods: A retrospective population-based propensity score-matched cohort study was conducted on the Chinese Electronic Health Records Research in Yinzhou database between January 2017 and June 2022. Prescriptions with the supply duration of antihypertensives >28 days were considered as longer-term prescriptions. The primary outcome was hospitalization for cardiovascular diseases. Secondary outcomes included medication adherence measured by medication possession ratio ≥80 % and visit frequency during the follow-up. Cox proportional hazard model and conditional logistic regression were used to estimate effects in the censored at treatment switch or discontinuation analyses.

Results: 25,625 adult hypertension patient pairs were included in the propensity score matched cohort. The median follow-up time was 180 days. Compared with patients receiving shorter-term prescriptions, lower hospitalization rates for cardiovascular diseases were observed in patients with longer-term prescriptions (hazard ratio: 0.88, 95 %CI: 0.80-0.98). The proportion of adherent patients in the longer-term group was higher than that in the shorter-term group (odds ratio: 1.91, 95 % CI: 1.84-1.98). The longer-term group also had fewer patients with ≥1 visit per month during the follow-up (odds ratio: 0.19, 95 %CI: 0.18-0.20). Subgroup and sensitive analysis showed consistent results.

Conclusions: Longer-term prescriptions can improve patients' clinical outcomes and decrease their visit frequency. Promoting longer-term prescriptions can help mitigate the challenge of limited health resources and reduce disease burden.

Objective: To enhance the quality of care and clinical outcomes for adolescents with Substance use disorder (SUD) and problematic substance use (PSU). The aims are twofold: 1) to summarize empirically-based guidance about the psychosocial, behavioral, and psychopharmacologic treatment of SUDs and PSU in adolescents and young adults; and 2) to summarize expert-based guidance about the assessment and clinical management of these disorders.

Method: Statements about the treatment of SUD / PSU are based upon empirical evidence derived from a critical systematic review of the scientific literature conducted by the Brown Evidence-Based Practice Center under contract with the Agency for Healthcare Research and Quality (AHRQ).

Background: Small studies have described the safety of uninterrupted direct oral anticoagulant (DOAC) use in atrial fibrillation (AF) patients undergoing elective, cardiac implantable electronic device (CIED) placement. Real-world practice patterns and associated outcomes remain poorly defined.

Objective: Describe DOAC usage trends following uncomplicated, outpatient CIED placement in AF patients and evaluate clinical outcomes based on DOAC status at discharge.

Background: Opioid and benzodiazepine co-prescription is associated with overdose, particularly among patients prescribed long-term opioids.

Objectives: Identify predictors of incident benzodiazepine and opioid co-prescription using two separate and complementary large-scale patient cohorts.

Design: Two retrospective cohort studies: (a) statewide dataset based on California's prescription drug monitoring program (PDMP, 7/1/2016-12/1/2018) and (b) national sample of commercial and Medicare Advantage enrollees from the Optum Labs Data Warehouse (OLDW, 7/1/2016-12/1/2021).
