PURPOSE Access to a usual source of care (USC) is associated with better preventive health and chronic disease treatment. Although most older adults have a USC, loss of USC, and factors associated with loss of USC, have not previously been examined. METHODS We followed 7,609 participants of the National Health and Aging Trends Study annually for up to 6 years (2011-2016). Discrete time-to-event techniques and pooled logistic regression were used to identify demographic, clinical, and social factors associated with loss of USC. RESULTS Ninety-five percent of older adults reported having a USC in 2011, of whom 5% subsequently did not. Odds of losing a USC were higher among older adults with unmet transportation needs (adjusted odds ratio [aOR] 1.67), who moved to a new residence (aOR 2.08), and who reported depressive symptoms (aOR 1.40). Odds of losing a USC were lower for those who had ≥4 chronic conditions (vs 0-1; aOR 0.42) and with supplemental (aOR 0.52) or Medicaid (aOR 0.67) insurance coverage. CONCLUSIONS We identified factors associated with older adults’ loss of a USC. Potentially modifiable factors, such as access to transportation and supplemental insurance, deserve further investigation to potentially assist older adults with continuous access to care.
