Medication Changes During Hospitalization and Readmission Among Older Patients with Heart Failure in Japan / 薬剤疫学

Objective：The number of heart failure （HF） patients is increasing in Japan as its population continues to age, but little is known about current medication strategies. We investigated the relationship between medication changes during hospitalization and the readmission rate among older Japanese patients with new-onset HF.Design：Retrospective cohort study.Methods：We analyzed medical record data from Toho University Medical Center Omori Hospital between March 2004 and April 2018. Initial admissions for new-onset HF in patients aged≥75 years were examined (n＝329). The class Ⅰ recommended medications stipulated in the JCS 2017/JHFS 2017 guidelines were used as the target medications for this study. Patients with dose titrations or additions of the target medications during hospitalization (dose titrations or additions group) were compared with patients without these changes (the other group). The primary outcome was readmission due to HF within one year of discharge. A hazard ratio, adjusted for potential confounders, was estimated using a Cox proportional hazards model.Results：There were 231 patients in dose titrations or additions group and 98 patients in the other group.The one-year readmission rate was 26.5％ in dose titrations or additions group and 31.8％ in the other group. The adjusted hazard ratio of medication changes for readmission was 0.82 (95％ confidence interval, 0.51-1.33, P＝0.415), but was not statistically significant.Conclusion：The older HF patients in dose titrations or additions group showed a reduced risk of readmission, but lacked significance due to low statistical power.

School-aged asthma children with high fractional exhaled nitric oxide levels and lung dysfunction are at high risk of prolonged lung dysfunction

BACKGROUND: Long-term management of bronchial asthma based on the fractional exhaled nitric oxide (FeNO) value alone is not conclusive yet. Therefore, we combined FeNO testing and spirometry, a commonly used test in routine practice, to evaluate acute exacerbation and respiratory function in children with bronchial asthma. OBJECTIVE: We combined FeNO testing and spirometry, commonly used in routine practice, to evaluate acute exacerbations and respiratory function in children with bronchial asthma. METHODS: Subjects were school aged children 7 years and older with bronchial asthma who underwent FeNO testing in January 2015 to May 2016. We evaluated the changes in the frequency of acute exacerbations and respiratory function in the 30 subsequent months. Subjects were divided into 2 groups: those with initial FeNO levels ≥ 21 parts per billion (ppb) (high FeNO) and < 20 ppb (normal FeNO) groups. RESULTS: There were 48 children (33 boys) in the high FeNO group and 68 children (46 boys) in the normal FeNO group. Spirometry was conducted on 83 children (72%) prior to the initial FeNO test, revealing no difference in the ratio of detecting lung dysfunction between the 2 groups. The observation period was 25.8 ± 0.7 and 24.7 ± 0.6 months for the high and normal FeNO groups, respectively. The children in the high FeNO group with lung dysfunction in the initial FeNO test continued to exhibit lung dysfunction at the test at 30 months. In the normal FeNO group, even if lung dysfunction was observed at the initial FeNO, it improved within the 20-month point, and the improvement was maintained thereafter. CONCLUSION: Children with bronchial asthma with high FeNO levels and lung dysfunction are at a higher risk of prolonged lung dysfunction.

Palliative care education using an e-learning system for hospital staff / 医学教育

1）Palliative care education by means e–learning was performed from December 3 to 25, 2009, for 1256 hospital medical staff. We used the same true–or–false questions to assess their understanding before and after the e–learning course.<br>2）Regardless of the staff member’s experience, the total scores on the test were higher after the course than before the course. Therefore, this e–learning course had an effect on basic knowledge for multiple types of medical staff.<br>3）The percentage of correct answers was particularly improved for questions about topics we had emphasized: drug dependence and side effects.

Development and evaluation of a new self-management system of administration of narcotic drugs for medical use in hospitalized patients

<b>Purpose</b>: In Japan, only a few studies reported self-management systems of narcotic drugs among hospitalized patients. Our purpose was to develop a self-management system for patients and assess its effectiveness. <b>Methods</b>: Based on the results of a questionnaire administered to our hospital medical staff, methods of selecting eligible patients and methods of self-management of narcotic drugs were determined by a multi-professional team. Selection criteria for eligible patients were: 1) satisfactory results on assessment of the patient's ability to self-manage orally-administered drugs; 2) satisfactory results on assessment of the patient's ability to self-manage narcotic drugs; 3) physician's consent was obtained; and 4) the patient wanted to participate in this program. After the period of self-management of drug administration, questionnaires were distributed to the patients and medical staff in the general ward. <b>Results</b>: One hundred hospitalized patients used narcotic drugs between April 2008 and March 2009. Among them, 26 patients met the criteria for self-management of narcotic drugs, and 20 voluntarily participated in the program. There were no reports of missing or stolen drugs. There were no reports of administration of incorrect dose of the drug during the self-management period (average 15.0 days). Ninety-four percent of the self-managing patients provided positive feedback about self-management of narcotic drugs, such as mental stability by having drugs on hand and no problems in self-management. Seventy-five percent of staff members answered that the self-management system of narcotic drugs should be continued. <b>Conclusion</b>: Our results suggest that this system of narcotic drug self-management is safe and appropriate.
