In 1994, a national hospital-based study was undertaken of cases of incomplete abortion presenting to public hospitals in South Africa. Data were collected for all women admitted to a random sample of hospitals with incomplete abortion during a two-week period. The WHO protocol for such studies was used as a basis for developing the methods to describe the epidemiology of incomplete abortion and hospital management of cases. Attempts were made to estimate the proportion of cases that might have been induced. This report focuses on methodological issues arising from the study that have implications for future research. The findings demonstrate that only a small proportion of the women acknowledged having had an induced abortion and that only a few of those who did showed evidence of interference with pregnancy. Clinical opinion of sepsis and the likelihood of induction were found to be highly unreliable. These findings considerably reduce the usefulness of the WHO-protocol method of estimating the likely origin of incomplete abortions. Results presented in terms of three partially overlapping descriptive categories are judged to better reflect the limitations of the data collected.
1994年，在南非开展了一项以医院为基础的全国性研究，研究对象为前往公立医院就诊的不完全流产病例。在为期两周的时间里，从随机抽取的医院中收集了所有因不完全流产入院的女性的数据。世界卫生组织（WHO）针对此类研究的方案被用作制定描述不完全流产流行病学及病例医院管理方法的基础。研究人员试图估算可能为人工流产的病例比例。本报告重点关注该研究中出现的、对未来研究有影响的方法学问题。研究结果表明，只有一小部分女性承认做过人工流产，而且其中只有少数人有妊娠受到干预的迹象。研究发现，关于败血症的临床判断以及人工流产可能性的判断非常不可靠。这些发现大大降低了WHO方案中估算不完全流产可能来源的方法的实用性。以三个部分重叠的描述性类别呈现的结果被认为能更好地反映所收集数据的局限性。
