The recording of surgical procedures for and diagnoses of nonmalignant gynecological conditions in the Danish National Hospital Registry in 1977-1988 were evaluated by comparison with discharge summaries for a sample of 4,919 women. A serious problem was found in the validity of the diagnoses. Little variation was seen over the period of observation. The coding of operations was considered valid. The results of the study raise concern in view of the widespread use of the registry data in medical research. The authors suggest that data from the registry should be thoroughly evaluated before firm conclusions based on such data are published, and that efforts to improve the validity of the data in the Danish National Hospital Registry are increased.
通过与4919名女性样本的出院小结进行比较，对1977年至1988年丹麦国家医院登记处记录的非恶性妇科疾病的外科手术过程和诊断进行了评估。发现诊断的有效性存在严重问题。在观察期内几乎没有变化。手术编码被认为是有效的。鉴于登记处数据在医学研究中的广泛使用，该研究结果引发了关注。作者建议，在基于此类数据发表确凿结论之前，应对登记处的数据进行全面评估，并加大提高丹麦国家医院登记处数据有效性的力度。
