INTRODUCTION:Existing evidence on clinical and economic effectiveness of one long-acting injectable antipsychotic (LAI) versus another in successful management of schizophrenia is scarce. The study was conducted to compare all-cause inpatient healthcare utilization and associated costs among Medicaid patients with schizophrenia who initiated LAIs.METHODS:This retrospective cohort analysis used the Truven Health Analytics MarketScan® Medicaid claims database. Schizophrenia patients >18 years with at least one claim for one of the following LAI were identified between 1 January 2013 and 30 June 2014 (identification period): aripiprazole, fluphenazine, haloperidol, paliperidone palmitate, and risperidone. The first day of initiating an LAI was considered the index date. Patients were followed for 1 year from index date. Logistic and general linear regression models were used to estimate risk of inpatient hospitalization and associated costs during follow up.RESULTS:Of the identified Medicaid patients with schizophrenia, 1,672 (36.7 percent) initiated an LAI: 44.0 percent received paliperidone, 26.4 percent haloperidol, 13.8 percent risperidone, 9.2 percent aripiprazole, and 6.6 percent fluphenazine. With the aripiprazole cohort as the reference group, the odds of having any inpatient hospitalizations were significantly higher in haloperidol [Odds Ratio, OR (95 percent Confidence Interval, CI): 1.51 (1.05 - 2.16)] and risperidone [OR (95 percent CI): 1.58 (1.07 - 2.33)] cohorts. Fluphenazine and paliperidone palmitate cohorts also had higher risk of having any inpatient hospitalizations compared with aripiprazole, but the differences were not statistically significant (p>.05). Among LAI initiators with any inpatient hospitalizations, the adjusted mean inpatient costs were lowest in the aripiprazole cohort (USD25,616), followed by haloperidol (USD30,811), paliperidone (USD30,833), risperidone (USD31,584), and fluphenazine (USD37,338), although differences were not statistically significant.CONCLUSIONS:Our study findings highlight the value of aripiprazole in reducing inpatient hospitalizations and associated costs among patients with schizophrenia. However, our study is limited as our results are reflective of a multi-state Medicaid population. Future studies are warranted to confirm the results in non-Medicaid patient populations.

Background: The use of antipsychotic long-acting injections (LAI) aims to reduce risk of relapse and hospitalisation in patients with schizophrenia compared with oral medication. Paliperidone palmitate is currently the only LAI that can be administered at three-monthly intervals for maintenance treatment of schizophrenia. Aim: This prospective study aimed to evaluate relapse and continuation in licensed use of paliperidone palmitate three-monthly (PP3M) over a 2-year follow-up in clinical practice. Method: Non-interventional, observational study of patients treated in the South London and The Maudsley NHS Foundation Trust. Results: A total of 166 patients initiated on PP3M, 55 were excluded from the study (non-F20 diagnosis ( n = 43); F20 >65 years old ( n = 12)). Of the 111 patients included, 67 (60%) continued PP3M for 2 years. Overall 102 patients received more than one dose of PP3M and 92 (90%) remained on the same dose of PP3M for the whole of their treatment duration. Relapse (defined as a step-up in clinical care) occurred in eight patients (7%) while on PP3M. The most common reason for discontinuation was patient refusal and the most frequent medication prescribed after discontinuation was paliperidone palmitate one-monthly (PP1M). Post hoc, we analysed outcome in those continuing any form of PPLAI (those continuing with PP3M and those switching back to PP1M). Continuation over 2 years with any PPLAI formulation was 73% (81/111) and relapse was recorded in 9% (10/111). Conclusion: Overall, PP3M was an effective maintenance treatment for schizophrenia after stabilisation on PP1M in a clinical setting.

Background: Limited data are available to help identify patients with schizophrenia who are most likely to benefit from long-acting injectable antipsychotics. Aim: To investigate the efficacy of long-acting injectable antipsychotic paliperidone palmitate one-month formulation for preventing relapses, factors influencing time to first relapse, and the effect of different antipsychotic adherence levels on time to first relapse in Chinese patients with schizophrenia. Methods: This was a post-hoc analysis from an open-label, single-arm study of stable patients (Positive and Negative Syndrome Scale total score <70; n=367) receiving paliperidone palmitate one-month formulation at the end of an acute 13-week treatment phase, who entered a naturalistic one-year follow-up period, either continuing with flexibly dosed paliperidone palmitate one-month formulation (75–150 mg eq.) or switching to another antipsychotic(s). Results: There were 362/367 patients (age=31.4±10.75 years) included in the analysis of time to first relapse (primary outcome) and 327/362 patients (39/327, poor antipsychotic adherence (<80%)) willing to receive antipsychotics were included in the exposure/adherence analysis. Overall, 84.6% (95% confidence interval=79.2–88.7) patients remained relapse-free. Poor adherence during follow-up (hazard ratio=2.97, 95% confidence interval=1.48–5.98, p=0.002) and frequent hospitalizations in the previous year (hazard ratio=1.29, 95% confidence interval=1.02–1.62, p=0.03) were associated with a significant risk of shorter time to first relapse in the univariate analysis. In patients with poor adherence, ‘no use’ (hazard ratio=13.13, 95% confidence interval=1.33–129.96, p=0.03) and ‘interrupted use’ (hazard ratio=11.04, 95% confidence interval=1.03–118.60, p=0.047) of paliperidone palmitate one-month formulation (vs continued use) showed a significantly higher risk of relapse; this was not observed in patients with good (≥80%) antipsychotic adherence. No new safety concerns were identified. Conclusion: Continued use of paliperidone palmitate one-month formulation/long-acting injectable antipsychotic was effective in preventing schizophrenia relapses, especially in patients with suboptimal antipsychotic adherence.

Incident Infection

Background: To examine the risk of infection in patients prescribed clozapine compared with patients prescribed paliperidone palmitate long-acting injection (PPLAI). Method: A retrospective, 1-year, cohort study conducted on events occurring in eligible patients beginning treatment for the first time with clozapine or PPLAI between June 2017 and June 2019 in a UK mental health trust providing in-patient and out-patient services. Results: The study included 64 patients starting clozapine and 120 patients starting PPLAI. Incidence of infection was greater in clozapine starters than in PPLAI starters (28% vs 6%; p = 0.001; adjusted odds ratio 5.82 (95% confidence interval (CI) = 2.15–15.76, p = 0.001). Infectious episodes in clozapine patients were not related to changes in neutrophil counts. Incident infection in the clozapine group was highest in the first 3 months of treatment. The most commonly reported infection in the clozapine group was chest infection; however, the majority of infections were non-chest-related. Conclusion: Patients starting clozapine showed a substantially increased likelihood of infection compared with patients starting PPLAI.
