      Highlights

      • There was a 14.3 % reduction in hospitalizations due to uterine fibroids.
      • There was a change towards more conservative treatments.
      • The rate of outpatients increased from 3.1%–22.1%.
      • The mean number of hospitalization days decreased from 6.3–4.0 days.
      • 0.5 % had an intraoperative complication and 2.3 % a post-operative complication.

      Abstract

      Objective

      To determine the trends of hospitalization (inpatients and outpatients) for uterine leiomyomas in Portugal, over a period of fifteen years.

      Study design

      We perform a population- and register-based retrospective study of women who were hospitalized with a primary diagnosis of uterine fibroid in public hospitals in continental Portugal, in the period between January 1, 2000 and December 31, 2015. Patient data regarding hospital codes, admission and discharge dates, patient age, diagnosis, procedures and complications were extracted from the national database of Administração Central do Sistema de Saúde (ACSS). All calculations were performed with the STATA software, version 13.1. Categorical data were analysed by the χ2 test and the means of continuous variables were analysed with Student’s t-test. Statistical significance was set at p < 0.05.

      Results

      Between 2000 and 2015, 102 476 patients were admitted to public hospitals in Portugal due to uterine leiomyomas. The majority were admitted to hospital for surgery: 73.6 % for hysterectomy and 13.0 % for myomectomy. During this period, the definitive treatment (hysterectomy) decreased from 83.2% to 63.0% (p < 0.001), with a change towards more conservative treatments such as myomectomies (6.4% to 22.6%, p < 0.001). Additionally, in women submitted to hysterectomy, laparoscopic and vaginal routes increased (1.1%–11.5%, p < 0.001 and 2.1%–4.0%, p < 0.001; respectively). Globally, there was a 14.3 % reduction in hospitalizations due to uterine fibroids and an increase in the outpatient rate (from 3.1% to 22.1%). The mean number of hospitalization days for inpatients also decreased (from 6.3 ± 4.1–4.0 ± 3.0, p < 0.001). Regarding urgently hospitalized women, 11.8 % required a blood transfusion. In women submitted to surgical procedures, 0.5 % had an intraoperative complication and 2.3 % a post-operative complication, directly related to the surgical procedure.

      Conclusion

      There was a reduction in hospitalizations due to uterine fibroids and a change towards more conservative treatments.
