“…19,20 We examined recorded diagnoses on medical claims using ICD-10 codes including asthma/chronic obstructive pulmonary disease (COPD; J43-J46), cancer (C00-C97), depression (F31-F33), diabetes mellitus (E10-E14), heart failure (I50), ischemic heart disease (I20-I25), Parkinson disease (G20), and stroke (I60-I64), according to previous studies. 5,21 The number of prescribed medications was counted as one for outpatient prescriptions for all formulations with the same generic name and route of administration.…”

“…3,4 Homebound older adults reportedly often receive multiple or potentially inappropriate medications. 5,6 In Japan, visiting pharmacists visit patients' residences (their homes or residential facilities) based on physicians' orders to serve individuals with limited access to community pharmacies. This improves medication adherence, reduces improper medication storage, and enhances drug supply.…”

AimTo investigate the factors associated with introducing visiting‐pharmacist services for community‐dwelling older adults in Japan.MethodsWe conducted a nested case–control study using claims data in a cohort from a city in Tokyo. Patients aged ≥65 years who received visiting‐pharmacist services for the first time between April 2014 and March 2020 were considered case patients. A maximum of four controls to each case patient were randomly selected on the basis of sex, age, health insurance systems, and month–year. Medical and long‐term care service usage and patient condition were assessed using claims data from the index and preceding months, along with long‐term care needs certification data. Multivariable conditional logistic regression analysis was conducted to estimate the adjusted odds ratios with 95% confidence intervals for factors associated with visiting‐pharmacist service introduction.ResultsA total of 22 949 participants (4591 cases and 18 358 controls) were included, with a median age of 85 years; 59.3% were women. The adjusted odds ratios (95% confidence intervals) of the three most related factors were 27.61 (23.98–31.80) for physicians' home visits, 5.83 (5.08–6.70) for hospitalization, and 4.97 (4.16–5.95) for designated‐facility admission. Factors such as prescribing ≧10 medications, visiting nursing, and cancer were positively associated. In contrast, low household income and a high need for support due to cognitive function or disability were negatively associated.ConclusionsThis study provides insights into the introduction of visiting‐pharmacist services for older adults in Japan.

“…However, it was reported that the prevalence of inappropriate polypharmacy was 70% among older adults receiving home medical care. 5 Inappropriate prescriptions do not always appear to be associated with care fragmentation.…”
