Arkansas implemented a primary-care case-management program in February 1994. This study evaluates the program during its first 17 months. Using quarterly data collected for the Health Care Financing Administration (HCFA), a pooled cross-sectional time series analysis (1991:4-1995:2) estimates the effect of eligibles' program enrollment on expenditure (total, inpatient hospital, outpatient hospital, physicians, prescription drugs, laboratory and X-ray) and utilization measures (outpatient visits, physician visits, prescription drugs). The Arkansas Medicaid managed care program appears to have somewhat reduced growth in total vendor payments and also appears to have improved access to primary medical services.
阿肯色州于1994年2月实施了一项初级保健病例管理计划。本研究评估了该计划最初17个月的情况。利用为医疗保健财务管理局（HCFA）收集的季度数据，采用汇总横断面时间序列分析（1991年第4季度至1995年第2季度）来估计符合条件者加入该计划对支出（总计、住院医院、门诊医院、医生、处方药、实验室和X光）及利用指标（门诊就诊、医生诊疗、处方药）的影响。阿肯色州医疗补助管理式医疗计划似乎在一定程度上降低了供应商支付总额的增长，而且似乎还改善了获得初级医疗服务的机会。
