OBJECTIVE

The number of indications for total hip replacement (THR) and total knee replacement (TKR) surgery is increasing. Enhanced recovery after surgery (ERAS) represents the next step in the evolution of standardised care. The primary aim of this study is to measure the in-hospital 30-day medical and surgical postoperative complications rate. The study's secondary aims are to determine the length of stay, 30-day mortality rate, 30-day reoperation and readmission rates, the ERAS overall compliance and predefined ERAS individual items compliance.

METHODS

This multicentre, prospective, observational study will include adult patients (aged >18 years) undergoing elective THR and TKR surgery. Consecutive patients undergoing surgery within the 2-month data collection period will be included. Centres that offer the THR and/or TKR surgery will be eligible to participate. The data collection will be done through an online data collection form via a secure, password-protected platform at each centre with predefined data fields.

RESULTS

Ethical approval for this study has been obtained from the Comité de Ética de la Investigación de la Comunidad Autónoma de Aragón (C.P.-C.I. PI18/135; on 23 May 2018). It was prospectively registered on 27 June 2018, at www.clinicaltrials.gov with identification no. NCT03570944.

CONCLUSION

The study will be disseminated through the SPARN-RedGERM, SEDAR, GERM and through social media. Peer-reviewed publications will be published under corporate authorship, including POWER.2 Study Group and SPARN-RedGERM.
