Abstract

Objective: To validate the Brazilian National Health System Hospital Information System (SIH/SUS) for maternal morbidity surveillance.

Methods: This was a cross-sectional study conducted in 2021/2022, taking as its reference a national study on maternal morbidity (MMG) conducted in 50 public and 28 private hospitals; we compared SIH/SUS and MMG data for hospitalization frequency, reason and type of discharge and calculated sensitivity, specificity, positive and negative likelihood ratios for seven diagnoses and four procedures.

Results: Hospitalizations identified on SIH/SUS (32,212) corresponded to 95.1% of hospitalizations assessed by MMG (33,867), with lower recording on SIH/SUS (85.5%) for private hospitals [10,036 (SIH/SUS)]; 11,742 (MMG)]; compared to MMG, SIH/SUS had a lower proportion of hospitalizations due to "complications during pregnancy" (9.7% versus 16.5%) as well as under-recording of all diagnoses and procedures assessed, except "ectopic pregnancy".

Conclusion: Better recording of diagnoses and procedures on SIH/SUS is essential for its use in maternal morbidity surveillance.

对巴西国家卫生系统医院信息系统中的产科住院数据进行验证研究，以监测孕产妇发病率：巴西，2021-2022 年。

目的验证巴西国家卫生系统医院信息系统（SIH/SUS）在孕产妇发病率监测方面的有效性：这是一项于 2021/2022 年进行的横断面研究，参照了在 50 家公立医院和 28 家私立医院进行的全国孕产妇发病率研究（MMG）；我们比较了 SIH/SUS 和 MMG 数据中的住院频率、出院原因和类型，并计算了七种诊断和四种手术的敏感性、特异性、阳性和阴性似然比：结果：SIH/SUS 系统识别的住院病例（32,212 例）与 MMG 系统评估的住院病例（33,867 例）的 95.1%相吻合，而私立医院 SIH/SUS 系统记录的住院病例较少（85.5%）[10]。与 MMG 相比，SIH/SUS 中因 "妊娠并发症 "住院的比例较低（9.7% 对 16.5%），除 "宫外孕 "外，所有诊断和手术均记录不足：结论：更好地记录 SIH/SUS 的诊断和手术对用于孕产妇发病率监测至关重要。
