[A survey on the utilization of internet services to collect job information among medical students and initiation of video public relations activities for the recruitment of public health physicians based on the survey results].

Objectives　It is difficult for medical students to obtain information about public health physicians because there are very few public health physicians near them. To improve this situation, we surveyed the utilization of internet services to collect job information among medical students and produced six videos and conducted public relations activities for the recruitment of public health physicians based on the survey results.Methods　The subjects of the survey were medical students in their third year or above from 18 universities. Public health teachers in these 18 universities sent their students anonymous self-administered questionnaires created with Google Forms mainly by e-mail. The questionnaires included the following items "internet services used to collect job information," "desired length of each video for knowing job information," and "information you want to know about your future work." The responses were reflected in the length and the content of the videos and the settings for their distribution.Results　Responses were obtained from a total of 491 medical students, including 14 third-year students, 177 fifth-year students, and 300 sixth-year students. Homepages were the most frequently used online source for collecting job information (94.7%), followed by blogs (42.0%), Twitter (32.6%), and YouTube (18.9%). Medical students are less likely to use social networking services for collecting job information compared with non-medical job-hunting students. Regarding the length of the videos, 55.8% of the respondents preferred the length of one video to be less than 5 minutes, and 95.1% preferred it to be less than 10 minutes. Almost all of the respondents (93.1%) wanted to know the atmosphere of young public health physicians, and 74.1% also wanted to know the atmosphere of veteran physicians. Based on these results, we selected six public health physicians including young and veteran physicians and produced interview videos that conveyed the atmosphere of each doctor within 5 minutes per person. We refurbished the banner on the top page of the Japanese Association of Public Health Center Directors so that the videos uploaded to YouTube could be watched.Conclusion　We clarified the current situation of the utilization of internet services for job-hunting activities among medical students and were able to initiate video public relations activities for the recruitment of public health physicians in accordance with the needs. It is necessary to increase awareness of the video platform among medical students and clinicians by deepening cooperation with local governments, universities, and medical institutions and expanding the human network both online and in person.

[Relationship between the number of public health nurses and the total number of people receiving home-visit nursing services for mental health/intractable diseases, and those numbers' regional differences].

Objectives　The primary aim of this study was to clarify the relationship between the number of public health nurses (PHNs) and the total number of people who received home-visit nursing services for mental health or intractable diseases. The secondary aim was to clarify the extent of regional differences in the number of PNHs and mental health or intractable diseases.Methods　This study used the total number of people who received home-visit nursing services for mental health or intractable diseases in 2019 from the Portal Site of Official Statistics of Japan (e-Stat) and population and area data in January 2020. Single and multiple regression analyses (covariates: population and area) were performed on the relationship between the number of PHNs per 100,000 population (abbreviated as "ratios of PHNs") and the total number of people who received home-visit nursing services for mental health or intractable diseases per 100,000 population (abbreviated as "mental health/intractable disease achievements"). Regional differences in ratios of PHNs and mental health/intractable disease achievement were examined using mean, standard deviation, maximum/minimum values, and Gini coefficients. Analyses were performed for each of the five units: the prefectures as a whole, prefectural public health centers, municipalities within the jurisdiction of prefectural public health centers, and cities in which public health centers are established (including or not including special wards).Results　Regression analyses indicated a positive relationship between the ratios of PHNs and mental health/intractable disease achievements. Multiple regression analysis indicated that both achievements were positively associated with population size and negatively associated with area size. The largest regression coefficients between the ratios of PHNs and achievements were 34.07 and 5.48 regarding mental health achievements and intractable disease achievements, respectively. For regional differences, the smallest Gini coefficient was the ratios of PHNs, and the largest was intractable disease achievements. The smallest and largest coefficient of the prefectures as a whole was 0.15 and 0.34, respectively. The maximum/minimum values of the prefectures as a whole also indicated that the smallest was 3.8 in the ratio of PHNs and the largest was 30.0 in intractable disease achievement.Conclusions　Increasing number of PHNs is needed to provide more home-visit nursing services for mental health and intractable diseases. It is particularly important to fill up the larger number of PHNs in smaller populations or larger area prefectures. Due to regional differences in the home-visit nursing service, it is important to promote the increase in the level of these activities.
