Treatment discontinuation of long-acting injectables or oral atypical antipsychotics among Medicaid recipients with schizophrenia

Abstract

Aims: Among patients with schizophrenia, poor adherence and persistence with oral atypical antipsychotics (OAA) often results in relapse and hospitalization. Second-generation antipsychotic long-acting injectables (SGA LAI) have demonstrated higher adherence than first-generation antipsychotic LAI and OAA therapies. This study aimed to determine whether SGA LAIs are associated with better persistency compared to OAA among Medicaid recipients with schizophrenia.

Materials and methods: From the MarketScan Medicaid Database (January 1, 2010–June 30, 2016), patients aged ≥18?years with schizophrenia and ≥2 pharmacy claims more than 90?days apart for the same SGA LAI or OAA were selected. New users of the specific antipsychotic agent were classified, based on their index agent, as: OAA, paliperidone palmitate LAI (PPLAI), aripiprazole LAI (ALAI), and risperidone LAI (RLAI). Discontinuation during 1 year of follow-up was defined as a?≥?60-day gap in the index OAA or SGA LAI medication past the exhaustion of the previous claim’s supply. Inverse probability of treatment weights (IPTW) balanced the cohort characteristics, and weight outliers (<0.1 or >0.9) were excluded. IPTW-weighted Cox proportional hazards regression estimated hazard ratios for discontinuation.

Results: Cohorts included 7,029 OAA, 4,302 PPLAI, 586 ALAI, and 1,456 RLAI patients. Mean age was 38.0–41.0?years and 44.0–46.6% were female. Persistence was significantly longer in the SGA LAI cohorts than in the OAA cohort. Adjusted hazard ratios (95% confidence intervals) for discontinuation were 0.60 (0.56–0.64) for PPLAI, 0.69 (0.60–0.79) for ALAI, and 0.70 (0.64–0.77) for RLAI vs OAA.

Limitations: Results may not be generalizable to patients covered by commercial or Medicare insurance, and limitations inherent to any claims-based retrospective analysis apply.

Conclusions: SGA LAI may be a valuable option for treating schizophrenia given the improvement in persistence.

Meeting threshold learning standards through self-management in group oral presentations: observations on accounting postgraduate students

This study explores the development of student self-management skills through an oral presentation task. It is motivated by the challenge to maintain consistent quality in students’ oral skills and to incorporate national accounting curriculum requirements for threshold learning standards into an accounting subject. The study has been conducted in Australia using a sample of postgraduate accounting students, and the task required the students to prepare a group presentation using action learning. The data were collected using in-class observation and a survey. Students indicated that they were more confident and comfortable in preparing and presenting the oral presentations as compared with their previous experiences. This was especially due to students having a second opportunity to improve their presentations allowing a better understanding of the expected standard. The oral presentation task benefitted all students but was especially useful for those who had limited experience speaking in front of a larger audience.
