Background: With increasing age globally, more people may become vulnerable to food choking. We investigated the nationwide epidemiology of food choking deaths in Japan.Methods: Using Japanese Vital Statistics death data between 2006 and 2016, we identified food choking deaths based on the 10th revision of the International Statistical Classification of Diseases code W79 (Inhalation and ingestion of food causing obstruction of respiratory tract) as a primary diagnosis. We assessed the demographics of people with food choking deaths; temporal trends of food choking deaths by the year (overall and by age group), the day of year; and prefecture variations.Results: Overall, 52,366 people experienced food choking deaths (median age, 82 years, 53% were male, and 57% occurred at home). The highest numbers occurred January 1–3, and were lowest in June. Despite a stable total number of cases at around 4,000 yearly, from 2006 to 2016 the incidence proportion declined from 16.2 to 12.1 per 100,000 population among people aged 75–84 years. Among people ≥85 years, the incidence proportion peaked at 53.5 in 2008 and decreased to 43.6 in 2016. The number of food choking deaths varied by prefecture.Conclusions: There are temporal and regional variations of food choking deaths in Japan, possibly due to the consumption of Japanese rice cake (mochi), particularly over the New Year’s holiday.

Background: Understanding the area-specific resource use of inpatient psychiatric care is essential for the efficient use of the public assistance system. This study aimed to assess the geographical variation in psychiatric admissions and to identify the prefecture-level determinants of psychiatric admissions among recipients of public assistance in Japan.Methods: We identified all recipients of public assistance who were hospitalized in a psychiatric ward in May 2014, 2015, or 2016 using the Fact-finding Survey on Medical Assistance. The age- and sex-standardized number of psychiatric admissions was calculated for each of the 47 prefectures, using direct and indirect standardization methods.Results: A total of 46,559 psychiatric inpatients were identified in May 2016. The number of psychiatric admissions per 100,000 population was 36.6. We found a 7.1-fold difference between the prefectures with the highest (Nagasaki) and lowest (Nagano) numbers of admissions. The method of decomposing explained variance in the multiple regression model showed that the number of psychiatric beds per 100,000 population and the number of recipients of public assistance per 1,000 population were the most important determinants of the number of psychiatric admissions (R2 = 28% and R2 = 23%, respectively). The sensitivity analyses, using medical cost as the outcome and data from different survey years and subgroups, showed similar findings.Conclusions: We identified a large geographical variation in the number and total medical cost of psychiatric admissions among recipients of public assistance. Our findings should encourage policy makers to assess the rationale for this variation and consider strategies for reducing it.

BACKGROUND: No studies in Japan have examined whether dispensing by family pharmacists, who are incentivized by reimbursement to provide continuous and exclusive medication management, results in prescription changes. Our primary objective was to identify the variables affecting prescription changes, particularly to investigate dispensing by family pharmacists as a possible factor.METHODS: We identified 333,503 records of pharmacy claims data from patients aged 65 years or older who received medication instructions at outpatient pharmacies at Tsukuba, a medium-sized city near Tokyo, between April 2018 and March 2019. We extracted data on dispensing by family pharmacists, number of medicines, patient sex, patient age, and pharmacy category. A multilevel modified Poisson regression analysis was performed to analyze the correlation between dispensing by family pharmacists and pharmacist-initiated prescription change.RESULTS: Dispensing by family pharmacists was 1.37 times more likely to involve a record of prescription change than dispensing by non-family pharmacists. Older age, female sex, polypharmacy, and small-scale pharmacies were also found to be factors.CONCLUSION: This study indicated that dispensing by family pharmacists was a potential factor for pharmacist-initiated prescription changes that may prevent excessive medication and limit pharmacological interactions. Since the likelihood of inappropriate prescriptions being issued varies from hospital to hospital, subsequent studies should take into account the quality of each institution.

Background: This study aimed to determine whether there are disparities in healthcare services utilization according to household income among people aged 75 years or older in Japan.Methods: We used data on medical and long-term care (LTC) insurance claims and on LTC insurance premiums and needs levels for people aged 75 years or older in a suburban city. Data on people receiving public welfare were not available. Participants were categorized according to household income level using LTC insurance premiums data. The associations of low income with physician visit frequency, length of hospital stay (LOS), and medical and LTC expenditures were evaluated and adjusted for the five-year age group and LTC needs level.Results: The study analyzed 12,852 men and 18,020 women, among which 13.3% and 41.5% were respectively categorized as low income. Participants with low income for both genders were more likely to be functionally dependent. In the adjusted analyses, lower income was associated with fewer physician visits (incidence rate ratio: 0.90 (95% confidence interval 0.87-0.92) for men and 0.97 (0.95-0.99) for women), longer LOS (1.98 (1.54-2.56) and 1.42 (1.20-1.67)), and higher total expenditures (1.09 (1.01-1.18) and 1.09 (1.05-1.14)).Conclusions: This study suggests older people with lower income had fewer consultations with physicians but an increased use of inpatient services. The income categorization used in this study may be an appropriate proxy of socioeconomic status.
