To validate the Brazilian National Health System Hospital Information System (SIH/SUS) for maternal morbidity surveillance.
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.
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".
Better recording of diagnoses and procedures on SIH/SUS is essential for its use in maternal morbidity surveillance.
验证巴西国家卫生系统医院信息系统（SIH/SUS）用于孕产妇发病率监测。
这是一项 2021/2022 年进行的横断面研究，以一项全国性孕产妇发病率（MMG）研究为参考，该研究在 50 家公立和 28 家私立医院进行；我们比较了 SIH/SUS 和 MMG 的住院频率、出院原因和类型数据，并计算了七个诊断和四个程序的敏感性、特异性、阳性和阴性似然比。
SIH/SUS 中记录的住院人数（32212 人）占 MMG 评估的住院人数（33867 人）的 95.1%，私立医院的记录较低（85.5%，SIH/SUS：10036 人；MMG：11742 人）；与 MMG 相比，SIH/SUS 因“妊娠并发症”而住院的比例较低（9.7% 对 16.5%），除了“异位妊娠”外，所有评估的诊断和程序的记录也较少。
为了将 SIH/SUS 用于孕产妇发病率监测，必须更好地记录诊断和程序。
