Study summary

This study estimates the impact of patient safety events on QoL in elective surgery patients using a secondary data set

Read the detailed description

Background: The burden of patient safety incidents (PSIs) is often characterised by their impact on mortality, morbidity and treatment costs. Few studies have attempted to estimate the impact of PSIs on patients' health-related quality of life (HRQoL) and the studies that have made such estimates primarily focus on a narrow set of incidents. The aim of this paper is to estimate the impact of PSIs on HRQoL of patients undergoing elective surgery in England.

Materials and Methods: A unique linked longitudinal data set consisting of Patient Reported Outcome Measures (PROMS) for patients with hip and knee replacements linked to Hospital Episode Statistics (HES) collected between 2013/14 and 2016/17 is examined. Patients with any of nine US Agency for Healthcare Research and Quality (AHRQ) PSI indicators are identified. HRQoL is measured using the general EuroQol five dimensions questionnaire (EQ-5D) before and after surgery. Exploiting the longitudinal structure of the data, exact matching combined with difference in differences to estimate the impact of experiencing a PSI on HRQoL and its individual dimensions, comparing HRQoL improvements after surgery in similar patients with and without a PSI.

Study population

The data available for our study was collected between 2013 and 2017. The patient safety incidents studied are relatively rare, and in order to yield enough observations to reliably estimate the impact of different incidents, the sample is limited to patients undergoing hip or knee replacements because these have more observations than do varicose veins and groin hernia. There are 267,477 and 288,967 observations for patients undergoing hip replacement and knee replacement respectively. Furthermore, the sample is limited to patients with observations of health status both before and after surgery.
