Treatment Burden Among Older Adults in the United States, 2022.

Background: Treatment burden refers to the patient-perceived effort of managing health and health care, which impacts quality of life and engagement in care. International studies of treatment burden have found high rates of treatment burden among adults with chronic conditions. However, the scope of treatment burden among US older adults is unknown. We described the prevalence of and characteristics associated with treatment burden among US adults age ≥ 50 years.

Methods: We performed a cross-sectional study of 1795 adult respondents to the 2022 Health and Retirement Study (HRS) Treatment Burden Questionnaire (TBQ), a random sub-sample from a nationally-representative panel study of community-dwelling US adults age ≥ 50 years. The primary outcome was total treatment burden score (15 items each scored 0-10, total 0-150; threshold ≥ 59 for high burden). We used multivariable linear regression to examine the association between log-transformed total treatment burden score and sociodemographic, health, and functional status characteristics.

Results: The mean age of 1795 respondents was 68.5 (SD 8.5) years, 56% were female, and the median TBQ score was 12 (IQR 5-25). Overall, 87% (n = 1550) reported treatment burden (TBQ score ≥ 1); 5% reported high burden. The most common sources of treatment burden were reminders of health problems (61%) and administrative (53%) and financial burdens (46%). Adults age ≥ 65 years were both less likely to report treatment burden and reported lower burden than adults age 50-64 years. Factors associated with greater burden included a higher number of chronic conditions, vision or hearing impairment, ADL/IADL difficulty, and mobility difficulty.

Conclusions: Most US adults age ≥ 50 years report treatment burden, though there is wide variation in the degree of burden reported. Reducing treatment burden within the US may require reducing administrative and financial burdens of care and addressing factors that impair patient capacity to manage health and health care.
