Objectives: There are few reports about patients hospitalized for COVID-19 in Japan. We investigated 200 patients hospitalized for COVID-19 over a 6-month period with the aim of elucidating their clinical characteristics and clinical courses.Methods: The study cohort comprised 200 patients hospitalized for COVID-19 during a 6-month period. We examined baseline characteristics, source of transmission, preadmission course, initial symptoms, concomitant symptoms, comorbidities, treatments, and prognosis.Results: The number of inpatients from outside our region increased from 9 in the second wave to 53 in the third wave. The initial manifestations were cold-like and gastroenteritis-like symptoms, gustatory and olfactory dysfunction being frequently occurring concomitant symptoms. On admission 32 patients had mild disease, 108 moderate I, 54 moderate II, and 6 severe. We divided the 200 patients into second and third wave groups and compared their baseline characteristics. The third wave group was older and had more severe disease. The main treatments implemented were dexamethasone and remdesivir. Three patients (1.5%) required ventilation and 12 (6.0%) died in hospital.Conclusions: We investigated 200 patients hospitalized for COVID-19 over a period of 6 months. The patients in the second wave were relatively young and most had mild disease. In contrast, the patients in the third wave were older and had more severe disease and higher in-hospital mortality.

Objectives: Erroneous use of inhalers is a serious problem. Given the multitude of devices currently available, it can be difficult to convey the correct methods for their efficient use to patients. We previously generated an educational DVD that visually and audibly explains the proper use of all inhaler types available in Japan to provide inhalation guidance to patients. Herein, we report the 1-year follow-up of patients who received or did not receive the DVD guidance.Methods: Sixty-nine bronchial asthma patients undergoing outpatient treatment who received inhalation guidance from a pharmacist using a standard package insert were randomly allocated to a DVD group (n=35) or a no-DVD group (n=34). Their current oral or inhalant drug regimens were unchanged. Various parameters were measured 12 months later. Frequencies of aggravation during the 12-month period were also determined.Results: Compared with the no-DVD group, there were significant improvements in asthma control test scores, forced vital capacity, FEV1, impulse oscillometry, resonant frequency, induced sputum eosinophil count, and FeNO in the DVD group after 12 months. Pulmonary function and inflammation parameters improved significantly with the use of the instructive DVD in addition to the package inserts. The frequency of asthma aggravation significantly decreased in the DVD group during the 12-month study period, likely because inhalation procedures were performed accurately.Conclusions: A DVD that provides accurate inhalation guidance enhances the quality of life of asthma patients and has substantial clinical ramifications. Thus, this tool would be beneficial for patients in Japan and worldwide.
