Consultations with patients who bring drugs, especially on the high risk drug list, to a hospital is an important role of pharmacists. However, many incident reports occur though pharmacists generally make an effort to check such medications. In Japan, incidents are mostly reported just in terms of numbers but not in terms of the prevalence of a target group. We aim to reveal the prevalence of incidents related to medicine brought-in by patients undergoing surgery in National Hospital Organization (NHO) hospitals. For our study, we extracted patients undergoing surgery who were prescribed antidiabetic agents from the Medical data bank (MIA) in NHO. Chart reviews were performed on patients to evaluate the number of incidents in relation to brought-in medicine. The prevalence of incidents of interest was 4.4% (41/931, 95%CL : 3.2-5.9%). Pre-avoidable incidents represented 56.1% (23/41, p<0.0001). We found that pharmacists play a role in making incidents less severe.

Objective: The clinical course of human metapneumovirus (hMPV) infection is similar to that of coronavirus 2019 disease (COVID-19). However, community-acquired hMPV infections in adults have not yet been sufficiently investigated. We examined the detection status of hMPV antigens and the clinical features of positive patients during the first wave of COVID-19, which coincided with the epidemic season of hMPV infection in Japan.Methods: In this cross-sectional, observational, and single-center study, we recruited consecutive individuals who visited the Japan Agricultural Cooperatives Kochi Hospital due to fever, respiratory symptoms, or close contact with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected persons during the period from January to May 2020.Results: The positive rate of immunochromatography for hMPV antigens from nasopharyngeal swabs was 9.5% (4/42), and four positive cases were community-acquired pneumonia (CAP) (5.3% of all CAP). The positive rate of hMPV antigens in the CAP group (30.8%, 4/13) was higher than that in the non-pneumonia group (0.0%, 0/19) (p < 0.05). The average age of the four adult patients with CAP was 69.8 years (range 35–93). Mean white blood cell counts and C-reactive protein blood levels were 6,250 cells/μL (3,500–12,180) and 4.30 mg/dL (4.05–7.04), respectively. Chest computed tomography images were diverse and two patients showed dense consolidation. No multi-organ disorder was noted during the clinical course in any of the four cases, and their prognoses were good.Conclusion: hMPV infection may be considered in the differential diagnosis of COVID-19 and CAP in Japan under the preventive measures for SARS-CoV-2 infection, at least during the epidemic season of hMPV infection.
