Background: In patients with Parkinson's disease (PD), long-term care insurance (LTCI), which can provide physical activity, might affect medical costs and utilization. We investigated the impact of LTCI on medical costs and utilization among patients with PD aged ≥60 years.

Methods: Data were derived from the 12-year Korean National Health Insurance Service‒Senior cohort. Among patients with newly developed PD, the intervention group receiving LTCI was matched with the control group using propensity score risk-set matching. As medical costs and utilization may increase markedly immediately before LTCI allocation, the baseline period was set from 5 years to 1 year prior to receiving LTCI. Medical costs and utilization were recorded in six 1-year intervals thereafter. We compared medical costs and utilization between groups using a comparative interrupted time-series analysis.

Results: 5011 LTCI beneficiaries and 5011 propensity score- and risk-set-matched controls were included. The overall mean (standard deviation) age was 77.73 (5.7) years, and 66.2% were women, in both groups. LTCI benefit was associated with reduced overall direct medical costs for 5 years (post-intervention year 5: -270$, p = 0.033), and overall hospital length-of-stay (LOS) for 2 years post-LTCI (post-intervention year 2: -2.43 days, p = 0.002), although medical costs and LOS increased immediately pre-LTCI implementation. The long-term care hospital LOS of LTCI beneficiaries increased relatively by 3-years post-LTCI implementation, particularly in those with a high Charlson Comorbidity Index score (post-intervention year 3: +2.65 days, p = 0.04).

Conclusions: LTCI benefit stably decreased medical costs for patients with PD for 5 years, despite the steep increase immediately pre-LTCI benefit, but was limited in reducing medical utilization, particularly as reflected by LOS in long-term care hospitals and patients with comorbidities. LTCI could be a useful health policy to reduce PD disease burden. However, further development is required to provide services that can reduce LOS to PD patients with comorbidities.
