ABSTRACT

Introduction: Vaccine policies have changed in recent years in Japan. In the present study, we assessed practices, recommendations, knowledge, and sources of information among primary care physicians (PCPs) regarding vaccinations in Japan. Methods: We conducted a nationwide cross-sectional study targeting PCPs in Japan. We used a web-based self-administered questionnaire targeting physicians that were members of the Japan Primary Care Association in 2019. We analyzed respondent administrations, recommendations, knowledge, and sources of information regarding vaccinations. Results: We received responses from 1,084 PCPs (20.1%) and invited 981 participants for the analysis. The rates at which physicians gave routine and voluntary vaccines in their own practices were 23.3-95.5% and 13.2-94.4%, respectively. The active recommendation rates for routine and voluntary vaccines were 41.6-92.0% and 13.6-75.5%, respectively. Furthermore, among routine vaccines, human papillomavirus vaccine was the least administered and recommended. PCPs working at clinics had the most accurate knowledge about vaccinations, and PCPs utilized academic organizations most readily as an information resource. Conclusion: We clarified practices, recommendations, knowledge, and sources of information regarding vaccinations among PCPs in Japan.

ABSTRACT

<b>Background:</b> Gingyo-gedoku-san (GGGS) is an herbal medicine approved for upper respiratory infections in Japan. We conducted an open-label, multi-center, prospective trial, comparing GGGS with oseltamivir in patients with influenza and influenza-like illness (ILI) as a pilot study.<br><b>Methods:</b> Subjects were healthy persons aged between 16 and 40, and were enrolled from January 12, 2010 to March 24, 2011. Fifteen patients were enrolled in this trial (8 and 7 for GGGS and oseltamivir, respectively). RT-PCR was positive for pandemic influenza A (H1N1) in 10 patients. The patients were provided with either GGGS or oseltamivir for 5 days. The primary outcome was mortality and/or hospitalization 7 days after the initial diagnosis. Body temperature and other clinical characteristics were also evaluated.<br><b>Results:</b> All patients recovered from illness without complication or hospitalization. The mean time to resolve symptoms for the GGGS and oseltamivir groups was 3.9 days and 3.3 days, respectively (p=0.43). The GGGS group appeared to have a smaller symptom score AUC than the oseltamivir group, (p=0.26). Time to recover activity level appeared to be shorter in the GGGS group (p=0.10), with shorter time to recover health status (p=0.02). Sub-group analysis on patients with positive PCR showed similar results between the two groups.<br><b>Conclusion:</b> GGGS was associated with symptom improvements resembling oseltamivir for both influenza and ILI. Randomized controlled trials involving larger sample sizes are needed to confirm these results.
