Background Currently, the evidence for lithium as a maintenance treatment for bipolar disorder type II (BD-II) remains limited. Guidelines commonly extrapolate recommendations for BD-II from available evidence for bipolar disorder type I (BD-I). Comparing the impact of lithium discontinuation is one way of assessing effectiveness in both groups. Aims To compare the impact of lithium discontinuation on hospital admissions and self-harm in patients with BD-I or schizoaffective disorder (SZD) and patients with BD-II or other bipolar disorder. Method Mirror-image study, examining hospital admissions within 2 years before and after lithium discontinuation in both patient groups. This study was part of a retrospective cohort study (LiSIE) into effects and side-effects of lithium for maintenance treatment of bipolar disorder as compared with other mood stabilisers. Results For the whole sample, the mean number of admissions/patient/review period doubled from 0.44 to 0.95 (P<0.001) after lithium discontinuation. The mean number of bed days/patient/review period doubled from 11 to 22 (P = 0.025). This increase in admissions and bed days was exclusively attributable to patients with BD-I/SZD. Not having consulted with a doctor prior to lithium discontinuation or no treatment with an alternative mood stabiliser at the time of lithium discontinuation led to more admissions. Conclusions The higher relapse risk in patients with BD-I/SZD suggests a higher threshold for discontinuing lithium than for patients with BD-II/other bipolar disorder. In patients with BD-II/other bipolar disorder, however, judged on the impact of discontinuation alone, lithium did not appear to prevent more severe depressive episodes requiring hospital admission.

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.

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.

IntroductionBipolar disorder (BD) is associated with periodic symptoms’ exacerbations, leading to functional impairment, substance abuse, and increased risk of suicide and accidents. Clozapine has never been approved for the treatment of BD but it is used in severe episodes.AimsThe aim of the study is to evaluate the risks and benefits of switching remitted BD patients treated with clozapine to another antipsychotic medication.ObjectivesWe assessed the proportion of relapsed patients after switching clozapine, time until relapse, type of relapse and the number of admissions.MethodsThis was an observational, mirror image study of 62 remitted BD outpatients treated with clozapine. Following a change in drug reimbursement rules by which clozapine was no longer reimbursable for patients with BD, 25 patients were switched to another antipsychotic and the rest of 37 continued on clozapine agreeing to pay treatment.ResultsThe mean score of CGI-BP at admission in study was in on both groups almost similar (2.3 vs. 2.4). After switching, a significant proportion of patients relapsed (77%), in 100% cases with a manic episode requiring hospitalisation. The mean YMRS score at relapse was significantly higher compared with the evaluation at the time prior to switching (31.78 (SD = 9.72) vs. 11.99 (SD = 7.29), P < 0.01).ConclusionsDespite the limitations of this naturalistic study, the results suggest that switching from clozapine to another antipsychotic may increase the risk of relapses in remitted patients with BD. The risks, costs and consequences of symptoms exacerbation should be weighed against the quest to control pharmacy costs.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Background: The pragmatic management of psychotic disorders is more complex than that delivered in a controlled trial environment. Therefore, this study aims to evaluate the real-world effectiveness of aripiprazole long-acting injectable (ALAI) and compare it with another commonly used long-acting anti-psychotic, once-monthly paliperidone palmitate (PP1M). Methods: This naturalistic, independent 4-year mirror image study compared the mean number and length of hospital admissions 2 years before and 2 years after treatment initiation with ALAI. Retention rates, discontinuation reasons and level of adherence were also recorded. Furthermore, indirect comparisons were made between treatment outcomes on ALAI and PP1M. Results: A total of 109 eligible patients with a severe mental illness (65% with schizophrenia and 35% with other diagnosis) commenced on ALAI and 173 patients (69% with schizophrenia and 31% with other diagnoses) initiated on PP1M were included. Of these, 37% on ALAI and 34% on PP1M stopped treatment at 2 years; retention rates were most favourable for the schizophrenia group on PP1M. Patients were more likely to discontinue due to lack of effectiveness on ALAI and due to tolerability issues on PP1M. Those who continued for 2 years on ALAI ( n = 69), demonstrated an overall decrease of 84% in the mean number and 88% in the mean length of hospital admissions compared with the 2 years before initiation. Although patients on ALAI appeared to have a significantly higher bed occupancy the 2-year period before initiation than patients on PP1M, the reductions in hospitalizations were comparable across both cohorts after 2 years of treatment. Conclusions: The introduction of ALAI had a substantial impact on long-term clinical outcomes in this naturalistic cohort; more than half of patients continued treatment and had no admission during 2 years of follow up. There were no significant differences in hospitalisation rates between patients on ALAI and PP1M at 2 years.

BackgroundClozapine is an atypical antipsychotic agent used primarily in the management of treatment-resistant schizophrenia. Previous studies have demonstrated clozapine’s superior efficacy over other antipsychotic medications in treating this population of patients. The aim of this study was to assess if the number of hospital admissions and days spent in hospital reduced with the initiation of clozapine, compared with when the same sample of patients were prescribed other antipsychotics prior to clozapine initiation.MethodA mirror-image study design was adopted. In this case the intervention under study was the initiation of clozapine. Information was collected retrospectively from the charts of patients attending the University Hospital Galway clozapine clinic. The number of admissions and number of hospital days were collected for each patient over the 3 years before and after clozapine initiation. Wilcoxon’s signed-rank test was used to test for statistical significance.ResultsThe total sample size comprised of 62 patients, of which the majority were male (74.2%) and had a diagnosis of schizophrenia (82.3%). The mean dose of clozapine was 417 mg, and mean age of the sample was 38 years. Mean number of hospital admissions reduced from 2.8 to 0.8 (p<0.0001) following initiation of clozapine. Mean number of days spent in hospital reduced from 116.4 to 17.1 (p<0.0001).ConclusionAfter initiation of clozapine treatment, patients experience a substantial reduction in number of hospital admissions and number of days spent in hospital when compared with a similar period prior to clozapine initiation.

AbstractBackgroundClinical trial outcomes are heavily influenced by the non-naturalistic clinical trial process. Observations of outcomes in clinical practice are a valuable adjunct to clinical trial results.HypothesisOur null hypothesis was that clinically indicated switching to paliperidone palmitate had no effect on hospital admissions or hospital bed days.MethodThis was a part-prospective mirror image study examining outcomes 2 years before starting paliperidone palmitate and 2 years after. Sensitivity analyses examined the effect of different placings of the mirror in the mirror image design.ResultsWe prospectively followed-up 225 patients prescribed paliperidone palmitate in clinical practice. At 2 years, 41.8% of patients were still receiving paliperidone palmitate. In the primary analysis, the mean number of admissions fell from 1.80 in the two years before starting paliperidone palmitate to 0.81 in two years following the drug’s initiation (outpatients) or two years following hospital discharge (inpatients) (P < 0.001). More than half of patients were not admitted to hospital during two years follow-up. Mean total bed days was reduced from 79.6 in the two years before to 46.2 in the two years after paliperidone palmitate initiation or discharge (P < 0.001). Sensitivity analyses gave broadly similar outcomes. Continuers demonstrated better outcomes than discontinuers in sensitivity analyses but not in the primary analysis.ConclusionPaliperidone palmitate initiation is associated with a substantial reduction in hospital admissions and days spent in hospital. The reduction in costs associated with reduced use of health care facilities is likely to exceed the purchase and administration costs of the drug.

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.

Introduction: A novel virus, SARS-CoV-2, has caused a fatal global pandemic which particularly affects the elderly and those with comorbidities. Hip fractures affect elderly populations, necessitate hospital admissions and place this group at particular risk from COVID-19 infection. This study investigates the effect of COVID-19 infection on 30-day hip fracture mortality. Method: Data related to 75 adult hip fractures admitted to two units during March and April 2020 were reviewed. The mean age was 83.5 years (range 65–98 years), and most (53, 70.7%) were women. The primary outcome measure was 30-day mortality associated with COVID-19 infection. Results: The COVID-19 infection rate was 26.7% (20 patients), with a significant difference in the 30-day mortality rate in the COVID-19-positive group (10/20, 50%) compared to the COVID-19-negative group (4/55, 7.3%), with mean time to death of 19.8 days (95% confidence interval: 17.0–22.5). The mean time from admission to surgery was 43.1 h and 38.3 h, in COVID-19-positive and COVID-19-negative groups, respectively. All COVID-19-positive patients had shown symptoms of fever and cough, and all 10 cases who died were hypoxic. Seven (35%) cases had radiological lung findings consistent of viral pneumonitis which resulted in mortality (70% of mortality). 30% ( n = 6) contracted the COVID-19 infection in the community, and 70% ( n = 14) developed symptoms after hospital admission. Conclusion: Hip fractures associated with COVID-19 infection have a high 30-day mortality. COVID-19 testing and chest X-ray for patients presenting with hip fractures help in early planning of high-risk surgeries and allow counselling of the patients and family using realistic prognosis.
