PAIN OUT is a multi-national, non-interventional registry and benchmark project, assessing and analysing clinical and patient-reported outcome data of postoperative pain.
PAIN OUT offers a large registry as well as a system for benchmarking and feedback of outcome quality and decision support in acute pain conditions. It collects demographic, clinical and outcome data, using a validated assessment tool available in multiple languages.
The registry part of the project aims at performing population-based research. Furthermore, its infrastructure allows for the conduct of prospective studies comparing the effectiveness of processes of care.
The benchmark part of the project provides the medical community with a unique, user-friendly system to improve treatment of patients with postoperative pain. A web-based information system, featuring two main functions, was developed:
PAIN OUT is leading and overseeing sub-projects in Mexico, China, a number of European countries. Additional countries will join over time. The sub-projects are scheduled to take place over a period of two years. The design is an uncontrolled pre- post-study, in which approximately 10 hospitals from each country participate. The project consists of collecting data (processes and patient reported outcomes) at baseline from 1-3 wards in participating hospitals; analyzing of the findings, selecting and implementing measures for change in practice; carrying out another round of data collection; summerizing the findings and discussing options for further work.
