ABSTRACT
Objective@#To identify factors affecting adherence to medication, a subjective questionnaire survey was administered to schizophrenia patients regarding the prescribed antipsychotic formulations. @*Methods@#We evaluated the patients’ satisfaction and dissatisfaction with prescribed antipsychotic formulations, and patients answered the Drug Attitude Inventory-10 Questionnaire (DAI-10). Inclusion criteria for patients are as follows:age between 20 and 75 years and taking antipsychotic agents containing the same ingredients and formulations, for at least 1 month. @*Results@#In total, 301 patients answered the questionnaire survey. Tablets were found to be the most commonly used antipsychotic formulations among schizophrenia patients (n = 174, 57.8%), followed by long-acting injections (LAIs, n = 93, 30.9%). No significant differences in the formulation satisfaction level and DAI-10 scores were observed between all formulations. Formulations, except for LAI, were selected by physicians in more than half of the patients.Patients who answered “Decided by consultation with physicians” had significantly higher satisfaction levels and DAI-10 scores compared to those who answered “Decided by physicians” (4.11 ± 0.77 vs. 3.80 ± 1.00, p = 0.0073 and 6.20 ± 3.51 vs. 4.39 ± 4.56, p ＜ 0.001, respectively). Satisfaction levels moderately correlated with DAI-10 scores (r = 0.48, p ＜ 0.001). @*Conclusion@#No formulation had a high satisfaction level in all patients, and it is important to be reflect the patients’ individual preferences in pharmacotherapy. Shared decision-making in the selection of the formulations is seen to be useful for improving medication adherence.
ABSTRACT
Objective@#To improve poor medication adherence in schizophrenic patients, long-acting injectable (LAI) antipsychotics are used. However, it has not yet become common in Japan. Recently, aripiprazole LAI was approved for alternative injection into the deltoid muscle in addition to the gluteal muscle. The acceptance for the proposal to switch from gluteal to deltoid injections of aripiprazole LAI was investigated. @*Methods@#The subjects were 32 outpatients with schizophrenia who had continuously received aripiprazole LAI administration into the gluteal muscle for ≥ 6 months. In the patients who had continued deltoid injection for 3 months after switching, the changes in the pain and shame in comparison with gluteal injections were evaluated. @*Results@#Switching to the deltoid injection was chosen by 17 out of 32 patients. Three months later, 9 patients were still receiving deltoid injections with highly rated satisfaction. The main reasons for switching to deltoid injections included the pain and shame associated with gluteal injections. The main reason for returning to the gluteal injection was the pain experienced from the injection in the deltoid. @*Conclusion@#The option to select the injected area was based on the amount of pain in the deltoid and gluteal sites, leading to the widespread use of aripiprazole LAI.
ABSTRACT
In Japan, drug therapy for schizophrenia is characterized by high-dose antipsychotic polypharmacy, which is an uncommon approach internationally. In this study, we reduced the number of antipsychotic agents in 5 patients using the Safety Correction of High-dose Antipsychotic Polypharmacy (SCAP) method and conducted a survey regarding treatment satisfaction. The switch from polypharmacy to monotherapy was achieved in all patients. There was no deterioration in psychiatric symptoms, and adverse reactions were reduced. Three of the subjects were satisfied with the decrease in the number of antipsychotic agents and dose-reduction. These results suggest that the SCAP method is a safe and useful method that can be applied in a clinical setting.
ABSTRACT
Objective：Currently, there is no reliable evidence on the usefulness of rehabilitation for idiopathic, normal-pressure hydrocephalus (iNPH）patients after cerebrospinal shunt surgery. Therefore, in this study we investigated the association between the duration of rehabilitation and outcomes.Methods：We evaluated the changes before and after cerebrospinal shunt surgery and rehabilitation by applying the 3-m timed up-and-go test (TUG), 10-m straight walk test, 180-degree turn, 30-seconds chair-stand test (CS-30), mini-mental state examination (MMSE), and frontal assessment battery (FAB) in 81 patients with iNPH. Clinical outcomes were classified as excellent, good, or unsatisfactory.Results：At discharge, TUG, 180-degree turn, and CS-30 were significantly improved in 38 patients who had been in rehabilitation for ≥2 weeks, compared to those with ＜2 weeks-rehabilitation after shunt surgery. However, there was no significant difference between MMSE and FAB tests in the two groups. Rehabilitation for ≥2 weeks significantly improved the patient outcome, especially for those patients with severe gait disturbance before treatment. In 53 patients whose initial TUG time was ≥13.5 s, rehabilitation for ≥2 weeks was effective, and resulted in an excellent outcome (odds ratio：4.52, 95％ confidence interval：1.22-18.7, P value：0.012).Conclusion：In-hospital rehabilitation after cerebrospinal shunt surgery was useful for patients with iNPH and severe disability in daily activities. Therefore, we suggest that these patients require in-hospital rehabilitation after shunt surgery until sufficient improvement of gait disturbance is achieved, in order to maximize activities of daily living.

ABSTRACT
Idiopathic normal pressure hydrocephalus (iNPH) is a disorder observed in elderly patients causing gait disturbance, urinary incontinence and cognitive impairment. Due to the rapidly aging society, the number of patients with iNPH continues to increase yearly. However, iNPH is often overlooked because of its insidious and variable presentation. In the primary care setting, iNPH can be coincidentally discovered by neuroimaging findings, including disproportionately enlarged subarachnoid space hydrocephalus (DESH). We report two cases of iNPH in the elderly living alone that had different outcomes depending upon the availability of neurosurgery specialists. It is essential for primary care physicians to consult neurosurgeons without delay because prompt diagnosis and treatment can improve the patient's quality of life and prolong their duration of living at home.
ABSTRACT
OBJECTIVE: Suvorexant is a novel hypnotic drug that does not interact with the conventional γ-aminobutyric acid (GABA)-A receptor. We investigated the method by which suvorexant was introduced in insomnia patients who were taking benzodiazepine receptor agonists (BzRA). METHODS: This was a retrospective study. We extracted clinical data for patients who were prescribed suvorexant and were already using BzRA. The patients were assigned to two groups, the switching and add-on groups. We assessed the suvorexant discontinuation rate at one month after the prescription of the drug. RESULTS: One hundred and nineteen patients were assigned to the switching group, and 109 were assigned to the add-on group. The add-on group exhibited a significantly higher all-cause discontinuation rate than the switching group (odds ratio, 2.7; 95% confidence interval, 1.5 to 5.0; adjusted p < 0.001). Intolerability was a significantly stronger risk factor for suvorexant discontinuation in the add-on group (22.0% vs. 7.6%, p < 0.002), and the most common adverse effect was oversedation. CONCLUSION: Our results show that the add-on of suvorexant increases the frequency of oversedation compared with switching in insomnia patients that are taking BzRA. However, this was only a preliminary retrospective study, and further studies will be required to confirm our findings.

OBJECTIVE: The adverse effects of antipsychotic agents can have a marked influence on medication adherence. In this study, we investigated the adverse events of antipsychotics that are less likely to be reported by patients and the reasons why such symptoms remain latent. METHODS: Data were collected by interviewing patients using a subjective questionnaire, and the associations between unreported symptoms and background factors were investigated. RESULTS: A total of 306 patients with schizophrenia or schizoaffective disorder were examined. Their major symptoms were daytime sleepiness (50.0%), weight gain (42.2%), and sexual dysfunction (38.9%). Sexual dysfunction was nominal significantly more common among the patients that had been treated with antipsychotic agent polypharmacy (odds ratio [OR], 2.14; 95% confidence interval [CI], 1.07 to 4.30), and was nominal significantly more common among outpatients (OR, 1.78; 95% CI, 1.02 to 3.13). Only approximately 30% of the patients had reported their symptoms to their physicians. CONCLUSION: Patients receiving antipsychotic treatment tolerate some symptoms and do not feel able to report them to their physicians. The most common reason for this is an insufficient patient-physician relationship. Sexual dysfunction is especially hard to identify because it is a delicate problem, and our findings demonstrate that subjective questionnaires are helpful for detecting such symptoms.

<b>Objective: </b>The purpose of this study was to clarify the importance of therapeutic drug monitoring (TDM) at acute care hospitals using Diagnosis Procedure Combination (DPC) data.<br><b>Methods: </b>We used DPC data from about 3,500,000 inpatients at about 950 acute care hospitals. The investigation period was from July 2010 to December 2010. Patients were divided into 2 groups: TDM intervention (<i>n</i>=22,012); and non-TDM intervention (<i>n</i>=26,400). We compared the clinical indicators (length of hospital stay, payment based on performance and drug costs) and use of antimicrobials.<br><b>Results: </b>TDM intervention was carried out in 45.5% patients for whom an anti-MRSA agent was prescribed. The duration of anti-MRSA agent administration was significantly longer in the TDM intervention group than in the non-TDM intervention group. The total daily cost of anti-MRSA agents was significantly lower in the TDM intervention group than in the non-TDM intervention group.<br><b>Conclusion: </b>Our results suggest that TDM intervention is often performed for seriously ill patients who require continuous treatment. TDM intervention may prevent adverse reactions as a result of adjusting the dosage of the anti-MRSA agent.
