Many studies have investigated spinal cord injury incidence rates. Few, however, have adjusted for the underascertainment. The current study used the capture-recapture method to estimate the ascertainment-corrected spinal cord injury incidence rate in Mississippi.
Two sources were used for case ascertainment: Mississippi's spinal cord injury registry and hospital reports. The two-sample capture-recapture method was used to adjust for undercount.
Two hundred one spinal cord injuries were reported to or found by the Mississippi State Department of Health in 1993, with a crude incidence rate of 7.8 per 100,000 population per year among hospital admissions and prehospital fatalities. Using the two-sample capture-recapture method, it is estimated that the incidence rate would be 9.3 per 100,000 population per year.
Capture-recapture estimates suggest that Mississippi's spinal cord injury incidence rate is more than twice the national average.
许多研究都调查了脊髓损伤的发病率。然而，很少有研究对漏报情况进行校正。本研究采用捕获-再捕获法来估计密西西比州经确定校正后的脊髓损伤发病率。
病例确定使用了两个来源：密西西比州脊髓损伤登记处和医院报告。采用两样本捕获-再捕获法对漏报情况进行校正。
1993年，密西西比州卫生部报告或发现了201例脊髓损伤病例，在住院患者和院前死亡病例中，粗发病率为每年每10万人7.8例。使用两样本捕获-再捕获法估计，发病率将为每年每10万人9.3例。
捕获-再捕获法估计表明，密西西比州的脊髓损伤发病率是全国平均水平的两倍多。
