AimsTo evaluate the effect of the use of aripiprazole and paliperidone long acting injections on healthcare resource useBackgroundLong acting injections of second-generation antipsychotics such as paliperidone and aripiprazole have become more commonly prescribed over the past decade. They have much higher acquisition costs when compared to first generation depot antipsychotics. It is therefore essential to demonstrate their tolerability and cost-effectiveness.MethodWe undertook an observational, retrospective two-year mirror study for all patients who started treatment with paliperidone long acting injection between January and June 2016 (n = 47) or aripiprazole long acting injection between April 2014 and July 2017 (n = 93). Clinical notes were examined to determine the number of admissions, inpatient days, home treatment episodes and number of home treatment days, in the 12 months preceding and following the commencement of the long acting injection.Result70% remained on paliperidone and 62% remained on aripiprazole at the end of the one-year period.There was a significant reduction in occupied bed days in those treated with paliperidone from 78.2 days in the year before this treatment was started to 25.4 days in the year after (p = 0.002). There was a significant reduction in occupied bed days in those treated with aripiprazole from 66.51 days to 32.7 days (p = 0.0006).There was no significant reduction in days spent under the care of home treatment teams for individuals treated with either of these medicines.ConclusionTreatment with either paliperidone or aripiprazole long-acting injection was associated with a reduction in admissions and occupied bed days of a magnitude that delivered an overall cost-saving despite the high drug acquisition costs. It remains to be determined how these reductions compare with other second-generation long-acting injections and first-generation depot antipsychotics.

Background: We sought to determine clinical outcomes of the prescribing of haloperidol decanoate long-acting injection (HDLAI) at 1 year. Method: A 1-year mirror-image study of 84 inpatients initiated on HDLAI. Admissions and bed days in the year preceding HDLAI were compared with the year after initiation. Predictors for discontinuation were evaluated. Results: At 1 year, 33% of patients remained on treatment. Patients starting HDLAI because of nonadherence were more likely to stop treatment [relative risk (RR) 1.72; 95% confidence interval (CI) 1.01, 2.91; p = 0.044] whilst patients with a longer duration of illness were more likely to remain on treatment (RR 0.88; 95% CI 0.78, 1.00; p = 0.050). In the bed days cohort overall, ( n = 65), there was a significant reduction in mean hospital admissions (1.4/patient/year to 0.6/patient/year; p = 0.0001) but not bed days (55.6/patient to 45.0/patient; p = 0.07) in the year following HDLAI initiation compared with the year before. Continuers had a significant reduction in mean bed days (53.1 to 4.0; p = 0.0002) and hospital admissions (1.5 to 0.2; p = 0.0001). Discontinuers demonstrated a significant reduction in hospital admissions (1.5 to 0.8; p = 0.0001) but not bed days (56.7 to 64.5; p = 0.83). Conclusion: HDLAI was associated with a high treatment discontinuation rate. Hospital admissions fell in the year after HDLAI but there was no change in bed days. Our study suggests that patients with a longer duration of illness and patients initiated on HDLAI for reasons other than poor adherence may benefit from HDLAI initiation.

Aims and backgroundAblify Maintena (AM) is a long acting injection of aripiprazole that received marketing authorisation in the UK in January 2014. It is costly compared to first generation antipsychotics (FGAs) LAIs and there are no robust trials comparing AM with FGAs. We examined the effectiveness and use of AM in a mental health trust.MethodsWe identified all patients prescribed AM in North Staffordshire (population: 470,000) since launch and examined records for demography, diagnosis, bed and medication use. We examined the effectiveness of AM using a mirror image design.ResultsThirty patients received AM in a time frame allowing a 1-year follow-up. Sixty-nine percent were male and the mean age was 39 years. Over half were detained under the 1983 Mental Health Act and 30% were inpatients on a psychiatric intensive care unit when AM was started. Twenty-eight patients had a psychotic diagnosis. There was a significant reduction in bed occupancy (63 v 6 days, P = 0.0001) and admissions (1.6 v 0.5, P = 0.0001). The median dose was 400 mg. Lack of effectiveness/poor adherence with prior treatments were the main reason for starting AM in 84%. Eighty-six percent of patients clinically improved on AM. Blood parameters were in the normal range.DiscussionWithin the limitations of the methodology, our results show a reduction in psychiatric bed use in the year following AM initiation on an intention to treat basis. The reduction in bed use equates to a minimum annual saving of £14,250 per patient. AM at the median study dose costs £2645 per year.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Objectives. Quantify changes in hospital resource use in Finland following initiation of risperidone long-acting injection (RLAI).Materials and Methods. A retrospective multi-center chart review (naturalistic setting) was used to compare annual hospital bed-days and hospital episodes for 177 schizophrenia patients (mean age 47.1 years, 52% female, 72% hospitalized) before and after initiation of RLAI (between January 2004 and June 2005) using the within-patient “mirror-image” study design. The base case analytical approach allocated hospital episodes overlapping the start date entirely to the preinitiation period. In order to investigate the impact of inpatient care ongoing at baseline, the change in bed-days was also estimated using an alternative analytical approached related to economic modelling.Results. In the conventional analysis, the mean annual hospitalisation costs declined by €11,900 and the number of bed-days was reduced by 40%, corresponding to 0.19 fewer hospital episodes per year. The reductions in bed-days per patient-year were similar for patients switched to RLAI as inpatients and as outpatients. In the modelling-based analysis, an 8% reduction in bed-days per year was observed.Conclusion. Despite uncertainty in the choice of analytic approach for allocating inpatient episodes that overlapping this initiation, consistent reductions in resource use are associated with the initiation of RLAI in Finland.

Background: The development of long-acting injectable formulations (LAIs) of second-generation antipsychotic drugs (SGAs) has been suggested as having advantage over first-generation antipsychotic (FGA) LAIs. In this study, we investigated the hypothesis that there was a longer time to relapse in patients with schizophrenia started on SGA LAI versus FGA LAI. Methods: Patients with a diagnosis of schizophrenia or schizoaffective disorder who were started on an SGA LAI while on an inpatient ward were identified through searching of the anonymised historical medical records at the South London and Maudsley NHS Foundation Trust. Patients starting FGA LAIs matched for diagnosis, age and date of hospital admission were identified. Time to readmission, discontinuation of LAI or death were identified. Kaplan–Meier plots were generated for each group, and the difference between groups analysed using log-rank methods. Results: There were 157 patients identified in each group. There was no difference in time to readmission, medication discontinuation or death in patients on SGA LAI versus FGA LAI. Conclusions: We found no evidence of advantage in terms of maintaining response in SGA LAI versus FGA LAI. Prescriber choice should be guided by other factors such as side-effect profile, patient acceptability and price.

Objectives: To evaluate the utilisation and persistence of antipsychotics for the treatment of schizophrenia in Australia. Methods: A retrospective study using the Australian Pharmaceutical Benefits Scheme database of a representative 10% sample. All adults with schizophrenia who were dispensed three or more supplies of oral (including clozapine) or long-acting injectable antipsychotics between 1 June 2015 and 31 May 2020 were included. Persistence time in treatment was evaluated using survival analysis and Cox hazard ratios. Results: In all, 26,847 adults with schizophrenia were studied. Oral second-generation antipsychotics were more frequently dispensed than the other antipsychotic groups studied. Median treatment persistence times were 18.3 months for second-generation antipsychotic long-acting injectables, 10.7 months for oral second-generation antipsychotics and were significantly lower for both formulations of first-generation antipsychotics at 5.2 months (long-acting injectables) and 3.7 months (oral). The median persistence time for clozapine was significantly longer than all other antipsychotics groups. Conclusions: Oral second-generation antipsychotics and second-generation antipsychotic long-acting injectables accounted for over 75% and 13% of all antipsychotics in Australia, respectively. Concerns over medication adherence and subsequent relapse have not translated into increased long-acting injectable usage despite their significantly longer persistence. Clozapine, the single most ‘persistent’ antipsychotic, was only used in 9% of people, although up to a third of all cases are likely to be treatment-resistant. Our data suggest clinicians should give consideration to the earlier use of second-generation antipsychotic long-acting injectables and clozapine, to ameliorate prognosis in schizophrenia.

Background: Previous studies showed a linear correlation between partial compliance with an oral antipsychotic medication and hospitalisation risk among patients with schizophrenia. Long-acting injections (LAIs) may significantly improve adherence and reduce relapse in patients with psychosis. The aim of this study was to evaluate the relationship between the level of compliance with 1-monthly paliperidone palmitate (PP1M) and hospitalisation rates. Methods: This was a naturalistic, mirror-image study examining retention, compliance and hospitalisation rates 3 years pre- and 3 years post-PP1M initiation. Compliance was divided in three groups: full (no missed dose/year), good (6–11injections/year), poor (<6 injections/year). Results: A total of 173 patients suffering from a severe mental illness (70% with a diagnosis of schizophrenia and 30% with other diagnoses) were included; 77% of patients continued PP1M for 1 year, 66% for 2 years and 55% for 3 years. Of the 95 patients who remained on PP1 throughout the 3 years of follow up, 81% showed full, 13% good, and only 6% poor compliance. In the patients who were fully compliant, the mean number of hospital admissions decreased from 1.34 to 0.43, and the mean number of bed days from 82 to 19 days per patient 3 years before and 3 years after PP1M initiation ( p < 0.001). It is noteworthy that the reductions in hospital stay were statistically significant for the group of patients with full compliance but not for the other two groups. In fact, patients with poor compliance demonstrated higher hospitalisation rates both before and after PPM1 initiation. These findings were similar in the subgroup of patients with schizophrenia who continued treatment for 3 years ( n = 68). Conclusion: There was a direct association between partial compliance and re-hospitalisation; fully compliant patients maintained the best outcomes in terms of reduced bed use following PPM1 initiation.
