[Need for Prescription Suggestions for Long-term Inpatients in the Psychiatric Ward].

Additional fees for ward pharmacists' services have been valued for hospitals in Japan. However, the calculation period for services provided to inpatients in the psychiatric ward is limited to 8 weeks. This study aimed to reveal the need for the services of pharmacists in the hospital ward for inpatients hospitalized for >8 weeks in the psychiatric ward. Patients who were hospitalized in the psychiatric ward from September 2016 to February 2017 were analyzed retrospectively. The pharmacists suggested prescriptions for inpatients admitted for >8 weeks, similar to those admitted for <9 weeks, and this supported pharmacotherapy without exacerbating patient outcomes. Moreover, significant decreases in benzodiazepine doses were found between the prior and post prescription suggestions of the pharmacist for inpatients >8 weeks of admission. Healthcare expenditures were also reduced. These results suggest that the prescriptions suggested by pharmacists for inpatients admitted for >8 weeks in the psychiatric ward were useful. In conclusion, our findings show that ward pharmacists' services were necessary not only for the inpatients hospitalized for <9 weeks, but also for those hospitalized for >8 weeks.

Economic impact of potentially inappropriate prescribing and related adverse events in older people: a cost-utility analysis using Markov models.

OBJECTIVES: To determine the economic impact of three drugs commonly involved in potentially inappropriate prescribing (PIP) in adults aged ≥65 years, including their adverse effects (AEs): long-term use of non-steroidal anti-inflammatory drugs (NSAIDs), benzodiazepines and proton pump inhibitors (PPIs) at maximal dose; to assess cost-effectiveness of potential interventions to reduce PIP of each drug. DESIGN: Cost-utility analysis. We developed Markov models incorporating the AEs of each PIP, populated with published estimates of probabilities, health system costs (in 2014 euro) and utilities. PARTICIPANTS: A hypothetical cohort of 65 year olds analysed over 35 1-year cycles with discounting at 5% per year. OUTCOME MEASURES: Incremental cost, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios with 95% credible intervals (CIs, generated in probabilistic sensitivity analysis) between each PIP and an appropriate alternative strategy. Models were then used to evaluate the cost-effectiveness of potential interventions to reduce PIP for each of the three drug classes. RESULTS: All three PIP drugs and their AEs are associated with greater cost and fewer QALYs compared with alternatives. The largest reduction in QALYs and incremental cost was for benzodiazepines compared with no sedative medication (€3470, 95% CI €2434 to €5001; -0.07 QALYs, 95% CI -0.089 to -0.047), followed by NSAIDs relative to paracetamol (€806, 95% CI €415 and €1346; -0.07 QALYs, 95% CI -0.131 to -0.026), and maximal dose PPIs compared with maintenance dose PPIs (€989, 95% CI -€69 and €2127; -0.01 QALYs, 95% CI -0.029 to 0.003). For interventions to reduce PIP, at a willingness-to-pay of €45 000 per QALY, targeting NSAIDs would be cost-effective up to the highest intervention cost per person of €1971. For benzodiazepine and PPI interventions, the equivalent cost was €1480 and €831, respectively. CONCLUSIONS: Long-term benzodiazepine and NSAID prescribing are associated with significantly increased costs and reduced QALYs. Targeting inappropriate NSAID prescribing appears to be the most cost-effective PIP intervention.

A pharmacoeconomic analysis of sertindole in the treatment of schizophrenia in Sweden.

BACKGROUND: Atypical antipsychotics have similar clinical efficacy in the treatment of schizophrenia; variability in their tolerability represents the discerning factor in treatment choices. Sertindole has a relatively good tolerability profile that favours long-term patient adherence and, therefore, is associated with lower rates of relapse and rehospitalization. AIM: A model was developed to compare the cost-effectiveness of a 5-year treatment strategy starting with sertindole versus olanzapine, risperidone, aripiprazole or the typical antipsychotic agent, haloperidol. METHODS: The model was based on published trials and local clinical practice, and considered costs from the perspective of the Swedish National Health Insurance Board. RESULTS: All atypical agents were clinically superior and more cost-effective than haloperidol with a cost per quality-adjusted life year gained of approximately 490,000 Swedish kroner. Sertindole was associated with the lowest direct and indirect medical costs, driven by its tolerability profile. CONCLUSIONS: Sertindole represents a useful alternative to the current treatment options available in Sweden. CLINICAL IMPLICATIONS: The relatively good tolerability profile of sertindole translates into lower costs of schizophrenia management, primarily driven by substantially lower direct and indirect costs. Sertindole appears to be a clinically and cost-effective alternative in the management of patients with schizophrenia in Sweden.

Comparison of health care use and costs in newly diagnosed and established patients with fibromyalgia.

UNLABELLED: In 2004, the American Pain Society (APS) issued evidence-based fibromyalgia treatment recommendations. The objective of this claims database analysis is to describe prescription and medical use in patients with newly diagnosed and established fibromyalgia. Privately insured patients with 2+ myalgia/myositis claims (1999 to 2005) were categorized as newly diagnosed or established; this dichotomy involves comparisons between prediagnosis (S1) and postdiagnosis (S2) stages in the newly diagnosed and between newly diagnosed (S2) and established patients (S3). Use of APS guideline medications increased across stages: selective serotonin reuptake inhibitors (SSRIs) (S1, S2, S3: 20.6%, 22.9%, 25.3%), serotonin norepinephrine reuptake inhibitors (SNRIs) (4.5%, 6.4%, 8.9%), pregabalin/gabapentin (5.4%, 7.4%, 8.8%), benzodiazepines (19.0%, 21.1%, 24.2%), non-benzodiazepine sedatives (9.1%, 11.5%, 13.7%) (all P < .0001), and opioids (39.5%, 43.3%, 43.9%; S1 vs S2, P < .0001; S2 vs S3, P = .2835). Use of multiple therapeutic classes also increased across stages: 3+ classes (7.1%, 9.6%, 11.8%) (all P < .0001). Office visits to providers increased, on average, after diagnosis: primary care (70.9%, 78.3%, 76.3%; all P < .0001), chiropractors (28.8%, 51.1%, 53.3%; all P < .0001), rheumatologists (4.2%, 9.9%, 10.5%; S1 vs S2, P < .0001; S2 vs S3, P = .0595), mental health (6.4%, 7.3%, 8.3%; S1 vs S2, P < .0001, S2 vs S3, P = .0003). Average health care costs rose after diagnosis in the newly diagnosed group (S1: $6555 vs S2: $8654, P < .0001). PERSPECTIVE: This paper investigates prescription drug and medical care use with respect to stages of fibromyalgia diagnosis. Established fibromyalgia patients use more medical resources and have higher rates of concomitant medication use than newly diagnosed fibromyalgia patients. Findings can help educate providers regarding optimal drug treatment patterns in this population.

A decision model to compare health care costs of olanzapine and risperidone treatment for schizophrenia in Germany.

Second-generation atypical antipsychotics such as clozapine, olanzapine, risperidone, quetiapine, ziprasidone, amisulpride and ariprazole offer the potential to reduce the significant health care resource demands in the treatment of schizophrenia through improved levels of initial clinical response and reduced levels of long-term acute relapse. However, the optimal sequencing of these drugs remains unclear. To consider this issue from a health economic viewpoint a decision model approach was used comparing healthcare costs and clinical outcomes when treating patients with alternative sequences of atypical antipsychotic treatment. Treated patients were assumed to be in a current acute episode with at least a 10-year history of disease and to be naive to previous atypical treatments. Treatment strategies were based on either first-line olanzapine or risperidone with switching to the alternative drug as second-line treatment following an inadequate clinical response to first-line drug therapy. Clinical response data were derived from a pivotal published comparative study of both olanzapine and risperidone. Published data on the long-term use of antipsychotic drugs where used wherever possible to populate the model for relapse rates during the maintenance phase. Health care resource data were defined for Germany based on expert clinical opinion. A treatment strategy of first-line olanzapine was shown to be cost saving over a 1-year period, with additional clinical benefits in the form of avoided relapses. The model suggests that over the first year of treatment a strategy of first-line olanzapine is associated with lower risk of additional relapse (0.33 fewer acute relapses per 100 patients per year) and with cost savings (euro 35,306 per 100 patients per year). There is a need for longer term direct in-trial comparisons of atypical antipsychotics to confirm these indicative results.

An economic comparison of risperidone and olanzapine use within an integrated managed mental health program.

This study assessed differences in total mental health care costs for 1 year following initiation of risperidone or olanzapine in individuals within NorthSTAR, an integrated managed mental health pilot project. A retrospective database analysis of individuals with schizophrenia or schizoaffective disorder and newly started on either agent was conducted. Antipsychotic medication costs were significantly lower for individuals prescribed risperidone than olanzapine (1763 dollars versus 2582 dollars; p<0.001). Individuals prescribed risperidone had lower (but not significant) expenditures for mental health services (4714 dollars versus 5077 dollars; p=0.792), as well as total mental health care costs (7407 dollars versus 9011 dollars; p=0.255).
