This study investigates the effect of long-term care insurance (LTCI) on medical expenditure and utilization in China and compares the effects between different pilot schemes.
We used four-wave data from the China Health and Retirement Longitudinal Study (CHARLS) 2011-2018, covering 19 cities piloted by national government or local governments. We applied a staggered difference-in-differences (DID) strategy to identify the effect of LTCI. Heterogeneity tests were used to identify the effects of different pilot schemes.
We found that LTCI implementation significantly reduces inpatient expenditure, annual inpatient visits, and monthly outpatient visits by 13.4%, 0.033, and 0.072, respectively. The effects of LTCI become more pronounced in pilot cities with government subsidies in financing or higher reimbursement ceilings. Compared to pilot schemes covering UEBMI & URRBMI program, the schemes only covering UEBMI program could significantly reduce inpatient and outpatient frequency by 0.029 and 0.069. Pilot schemes with more service items had lower outpatient frequency (β = -0.146), and pilot schemes with fewer service items had lower inpatient expenditure and frequency (β = -0.226 and β = -0.049).
In general, this study found that LTCI implementation could effectively reduce the expenditure and utilization of medical services. The effects of different pilot schemes vary significantly. The results of this study further supplement the existing empirical evidence on the effect of LTCI and provide important policy implications for the future development of LTCI in China and other developing countries.
本研究探讨长期护理保险(LTCI)对中国医疗支出和利用的影响,并比较不同试点方案之间的效果。
我们使用了中国健康与养老追踪调查(CHARLS)2011 - 2018年的四期数据,涵盖了由国家或地方政府试点的19个城市。我们应用交错差分法(DID)策略来确定长期护理保险的效果。通过异质性检验来确定不同试点方案的效果。
我们发现,长期护理保险的实施显著降低了住院支出、年度住院次数和月度门诊次数,分别降低了13.4%、0.033和0.072。在有政府融资补贴或更高报销限额的试点城市,长期护理保险的效果更为显著。与覆盖城镇职工基本医疗保险(UEBMI)和城乡居民基本医疗保险(URRBMI)项目的试点方案相比,仅覆盖UEBMI项目的方案可显著降低住院和门诊频次,分别降低0.029和0.069。服务项目更多的试点方案门诊频次较低(β = -0.146),服务项目较少的试点方案住院支出和频次较低(β = -0.226和β = -0.049)。
总体而言,本研究发现长期护理保险的实施可有效降低医疗服务的支出和利用。不同试点方案的效果差异显著。本研究结果进一步补充了关于长期护理保险效果的现有实证证据,并为中国及其他发展中国家长期护理保险的未来发展提供了重要的政策启示。
