# Hysterectomy rates per resident in final year of training in teaching hospitals: an ecologic study

## TL;DR

This study examines how the number of hysterectomies performed per resident in their final training year changed in teaching hospitals in São Paulo, Brazil, from 2009 to 2019.

## Contribution

The study provides new insights into the relationship between resident training and surgical trends in hysterectomy rates and techniques.

## Key findings

- Hysterectomy rates per resident dropped by 24.1% between 2009 and 2019.
- The decline was most significant for vaginal (46.4%) and abdominal (23.3%) routes.
- Laparoscopic hysterectomies increased 264% but remained a small proportion of surgeries in 2019.

## Abstract

Analyze the hysterectomy rates per resident in graduation year in teaching hospitals in the state of São Paulo (Brazil).

We selected teaching hospitals in the state of São Paulo and gathered information from two public databases to estimate the hysterectomy rates per resident in their final year of training between 2009 and 2019.

Between 2009 and 2019, there was a 37.5% increase in the number of residents in their final year of training, a 4.31% increase in the number of hysterectomies, and a drop in the hysterectomy rates per resident of 24.1%. The reduction of the rate of hysterectomy per resident was more pronounced for vaginal route (46.4%) followed by abdominal route (23.3%). The ratio of laparoscopic hysterectomy per resident increased 264% during the period, however, this route was used in only 7% of the surgeries in 2019.

The hysterectomy rates per resident in their final year of training showed a notable reduction. This trend, particularly pronounced in vaginal and abdominal routes, signals a shift towards minimally invasive techniques.
