Epidemiology of Perioperative Care in Sweden — EPeCS  

Surgery Clinical Trial

Official title: EPeCS - Epidemiology of Perioperative Care in Sweden 2015-2020

Status Active, not recruiting

Clinical Trial Summary

The Epidemiology of Perioperative Care in Sweden (EPeCS) study is a registry-based, retrospective extensive analysis of the whole adult (≥18 years) surgical population in Sweden during six full years, 1 January 2015 - 31 December 2020. Patients are retrieved from the Swedish Perioperative Registry (SPOR) which has full national coverage of public healthcare. The study aspire to integrate pre-, peri- and postoperative components of the whole perioperative process as well as process, patient, anaesthesia and surgical factors. This allows for careful risk-adjustment and is a major strength of the project. This will require cross-matching data from several national quality registries. EPeCS will serve as a database to be used as the foundation for several substudies that are to be conducted (10 at the present moment). Specific study focuses and aims are described in the "Detailed Description" section below. The present study aims to provide a comprehensive audit of the surgical population in Sweden, and to identify factors that are of importance for outcome. The investigators aim to identify factors that will allow a better prediction of outcome, if they are modifiable, and if they are different for different lengths of follow-up. The ultimate goal is to provide hypotheses for directed therapies (eg. different types of anaesthesia), processes (eg. designated around-the-clock hip-fracture surgical teams), postoperative care (eg. extended PACU care instead of intensive care) in order to decrease suffering and increase cost-efficacy in Swedish healthcare.

Clinical Trial Description

Specific aim for each substudy: 1. Epidemiology of Perioperative Care in Sweden 2. Risk factors for mortality after acute hip fracture surgery 3. Healthcare need after surgery 4. outcomes after urgent and emergency surgery 5. impact of estimated glomerular filtration rate (eGFR) on survival after elective surgery 6. effect of angiotensin receptor blocker (ARB) and angiotensin converting enzyme inhibitor (ACEi) non-resumption on postoperative outcome 7. impact of socioeconomic status 8. impact of university hospital status 9. effect of body mass index (BMI) 10. effect of post-anaesthesia care unit (PACU) stay All these 10 specific areas have knowledge gaps regarding perioperative care. Although there are 10 specific aims in this project, the same dataset (or parts thereof) from SPOR will be used for all substudies. The investigators will include all adult patients (≥18 years) undergoing any surgical procedure, except for the substudies where specific populations are prespecified, which are substudy 2: hip fracture surgery; substudy 4: urgent and emergency procedures; substudies 5,6 and 10: elective procedures with planned overnight stay; substudies 7 and 8: large joint surgery (hip and knee replacements), acute hip fracture surgery, colectomy, mastectomy, transurethral resection of the prostate (TUR-P) and prostatectomy. Outcome measures might also differ between substudies. National Quality Registries that will provide data for EPeCS, presented as "register (registry holder)": - Swedish Perioperative Registry, SPOR (Uppsala Clinical Research Centre, UCR) - Longitudinal integrated database for health insurance and labour market studies, LISA (Statistics Sweden) - Swedish National Inpatient Register (the National Board of Health and Welfare) - Swedish National Outpatient Register (the National Board of Health and Welfare) - Swedish Drug Register (the National Board of Health and Welfare) - Swedish Cause of death Register (the National Board of Health and Welfare) The impetus for this project comes from the realization that surgery is not just a discrete event - it is part of a continuum of a larger journey of illness and health. The investigators hope to gain a comprehensive understanding of those patients who are at risk of poor outcome, their risk of death and burden of healthcare need after surgery. Additional substudies might emerge. ;
