摘要
Background: China has made major improvements to its health-care system since the early 21st century. However, the effectiveness of preventive care utilization on health-care costs remains limited. This study seeks to understand the effect of preventive care utilization on outpatient and inpatient health-care expenses. Methods: With the use of the Chinese Longitudinal Healthy Longevity Survey with older adults who were 65 years old or above (n = 2828), Tobit regression models were estimated to examine the association of preventive care utilization and expenses with medical treatments. Preventive care utilization in the previous wave was used to predict health-care costs for treatments in the next wave. Propensity score matching was used to reduce potentially confounding factors. Findings: Results indicated that preventive care utilization was positively associated with outpatient health care among Chinese older adults (β = 231.8, standard error [SE] = 71.5, P <.01). The association between preventive care utilization and inpatient health-care expenses was not significant. Conclusions: Despite the results from previous studies suggesting that preventive care utilization can help reduce health-care expenses, this study does not support such a claim among Chinese older adults. The long-term association between preventive care utilization and health-care expenses for treatment should be studied further.
