Objectives To investigate the prevalence of chronic comorbidities and the use of comedications in people living with HIV (PLWH) and on antiretrovirals in Japan, by using a hospital claims database.
Design Observational, retrospective, cross-sectional study.
Setting A hospital claims database of Japanese hospitals that have advanced medical treatment capabilities (ie, advanced treatment hospitals, general hospitals, acute care hospitals), which include those providing acute and chronic care (excluding nursing homes or hospices).
Participants A total of 1445 PLWH aged ≥18 years and with a prescription record of antiretrovirals between January 2010 and December 2015 were identified from the database.
Outcome measures The number and types of chronic comorbidities, as well as the number and types of comedications, in different age groups of the PLWH.
Results The median (range) age of patients was 45 (18–90) years, and 90.4% were men. Of the 1445 patients, 972 (67.3%) had at least one chronic comorbidity. Common chronic comorbidities included lipid disorders (31.6%), diabetes (26.8%), hypertension (18.2%) and hepatitis B/C coinfection (18.2%). Patients in the older age groups had greater numbers of chronic comorbidities. The most common chronic comorbidities in the older age groups were hypertension, diabetes and lipid disorders. The majority of patients used at least one comedication, and those in the older age groups used greater numbers of comedications. The most common therapeutic category of comedication included antacids, antiflatulents and antiulcerants (31.7%). Of 151 malignancies reported in 117 patients, 84 were AIDS-defining cancers and 67 were non-AIDS-defining cancers.
Conclusions Chronic comorbidities and comedications were common among PLWH in Japan taking antiretrovirals; particularly among older patients, who more frequently used comedications. This suggests the need for giving special attention to the appropriate management of this patient population.
