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.

Objective: We study compulsory community treatment orders (CTOs) for patients with severe and persistent mental illness (SPMI). Focusing on a unique jurisdiction in Canada that allows for long duration CTOs with strict enforcement procedures, our objectives are to determine whether extended duration CTOs are effective and to determine whether associated hospitalization costs are reduced. Method: A mirror image, naturalistic design was employed using patients as their own controls to enhance external validity. No inclusive or exclusive criteria were employed for the 367 SPMI clinic patients who were studied over a 5-year period. Detailed documentation of the dates of all CTOs, long-acting antipsychotic injections (LAIs), emergency visits, hospitalizations, duration of hospitalizations, crimes and/or police involvement were collected. To study the relation between CTO and injection adherence, we use a mixed-effect linear regression model. To study the effect of injection adherence and hospitalization, we use survival analysis via Kaplan–Meier and Cox survival models. Results: CTO and non-CTO patients did not differ with respect to demographics, but CTO patients were significantly more severely ill. Following a CTO, adherence to LAIs increased over time ( P < 0.001). The average time the patients spent in the community, that is, outside the hospital, was significantly longer under a CTO, and the duration of hospitalizations was decreased. Conclusions: LAI adherence and outpatient office visits were enhanced by extended duration CTOs, as was time out of the hospital. The shorter duration of hospital stays implies cost savings. These must be weighed against their undesirable coercive nature.

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.

AbstractBackgroundAripiprazole once-monthly is an LAI formulation of aripiprazole that is currently approved in the USA and Europe for the treatment of schizophrenia. Some studies have reported a decline in hospital admissions and emergency use after initiation on long-acting injectable (LAI) antipsychotics, but the effects of using recently commercialised LAI aripiprazole remains uncertain.AimsTo characterize the impact of ALAI initiation on number of hospitalizations and visits to the emergency service, among patients suffering from schizophrenia attending regularly to psychiatric consultations of Gregorio Marañón University General Hospital (Madrid, Spain).MethodsPatients initiated on (ALAI) were studied in an observational mirror-image design to assess changes in number of hospitalizations and visits to the emergency service in the 12months pre- vs 12months post-depot initiation. Other sociodemographic, physical and clinical variables such as age, gender, weight, blood pressure and presence of dual disorders were also gathered. Variables were collected reviewing clinical records.Wilcoxon test was used to assess hospitalizations and visits to the emergency. Paired t-tests were used to assess changes in weight and blood pressure. Non parametric Mann-Whitney U test was used to compare aripiprazole doses between genders and in order to assess de influence of dual disorders. In order to perform the statistical analysis, IBM SPSS statistics v.20 was used.Results31 patients were included in the final analysis. Mean age was 44.67 (SD=15.57) years. Most of the patients were male (54.8% vs 45.2%). 71% were previously receiving oral antipsychotics treatment, whereas 29% were receiving other LAI antipsychotic: no significant differences were observed when comparing hospitalizations (p=0.74) or emergency use (p=0.98) in the 12months post-initiation between these groups. Mean dosage was 352.67mg/28days (SD=0.461), and 38.7% needed an adjustment during the first year of treatment (dosage increased in 76.9%). A combination of two or more antipsychotics was prescribed in 64.5% of the patients. Mean psychiatric number of hospitalizations a year declined from 0.483/year pre-initiation to 0.224/year post-initiation (P<0.05), whereas mean visits a year to the emergency psychiatric service declined from 1.419 pre-initiation to 1.032 post-initiation (P<0.1). No significant changes in weight (p=0.82), systolic (p=0.56) or diastolic (p=0.29) blood pressure were observed. No gender differences in dosage were observed (p=0.246). Suffering from dual disorders had no influence on dosage either (p=0.68).ConclusionsLAI aripiprazole initiation appears to provide a benefit decreasing hospitalization needs and emergency services consumption and it was well tolerated. This data supports previous evidence indicating superiority of LAI antipsychotics.
