过去检查病案书写质量,或治疗效率、诊断符合等指标,通常是用抽取很小一个样本的方法,比如20份病案,核定后分出甲、乙、丙级(一般不应有丙级病案)。这种办法起码有两点不足:第一,不同规模医院抽取同样规模样本,是不妥当的。例如较大的医院,全年检查抽取20份出院病案,它的代表性是很不可靠的。第二,由 In the past, the quality of medical records, or treatment efficiency, diagnostic compliance, etc., was usually measured by taking a small sample, such as 20 medical records, which were assigned to grades A, B, and C after approval (generally, there should be no grade C illness). .
