Abstract

Introduction: Obstetric hysterectomy, although a relatively safe procedure, may present complications.

Objective: The study aimed to analyse how therapies and staging are related to the survival of pregnant women with obstetric hysterectomy in the population of Ecuador, during the period 2019-2022.

Methods: The study was retrospective, analytical, observational, longitudinal and predictive. The population was 132 obstetric hysterectomy patients attended in a hospital in Ecuador. Cox regression analysis was performed.

Results: Six cases (4.5 %) were observed where the event of interest (survival or death) of patients after obstetric hysterectomy was recorded. The log likelihood -2 had a value of 46.461. The overall significance of the model was: Chi-square = 49.641; df = 4; p < 0.001. For staging, a positive coefficient with a p-value of 0.116 (>0.05) was observed, indicating that this variable was not statistically significant in relation to survival, while for Blood transfusion and Additional surgery, high p-values (>0.05) suggested a lack of statistical significance in their effects on survival. However, for Antibiotics, the high p-value indicated a lack of statistical significance in this model.

Conclusions: There was insufficient statistical evidence to reject the null hypothesis (H0). This meant that, it cannot be stated that any of the variables considered have a significant impact on patient survival after obstetric hysterectomy.
