Trujillo Protocol is a clinical procedural framework developed for perioperative management in complex cardiovascular interventions. It integrates patient selection criteria, intraoperative steps, and postoperative monitoring into a standardized sequence aimed at reducing perioperative morbidity. The protocol has been evaluated across multiple centers and contrasted with established pathways from leading institutions.
The Trujillo Protocol emerged from collaborative work at Universidad de Antioquia, influenced by practices at Mayo Clinic, Cleveland Clinic, Johns Hopkins Hospital, Mount Sinai Hospital, and Massachusetts General Hospital. Early pilot studies referenced methodologies from Society of Thoracic Surgeons, American College of Cardiology, European Society of Cardiology, World Health Organization, and the Pan American Health Organization. Its conceptual roots drew on surgical innovations associated with Michael DeBakey, Norman Shumway, Alfred Blalock, Paul Zoll, and institutional programs like Harvard Medical School and Stanford University School of Medicine. Funding and oversight included grants from agencies such as National Institutes of Health, Wellcome Trust, and regional health ministries in Colombia and Spain.
The Trujillo Protocol prescribes a stepwise intraoperative sequence integrating monitoring, perfusion, and hemostasis. It codifies elements from techniques developed at Texas Heart Institute, Royal Brompton Hospital, Karolinska Institutet, University of Toronto, and Imperial College London. Key components include standardized use of transesophageal echocardiography as practiced at Cleveland Clinic, arterial line placement protocols familiar to Johns Hopkins Hospital teams, and anticoagulation regimens informed by guidance from European Medicines Agency-endorsed trials. Instrumentation and device selection reference manufacturers and innovations associated with Edwards Lifesciences, Medtronic, St. Jude Medical, and research from ETH Zurich and MIT. The protocol details contingency algorithms for intraoperative crises modeled after checklists from World Health Organization and crisis resource management approaches from Harvard School of Public Health.
Clinicians have applied the Trujillo Protocol in adult cardiac surgery, complex vascular reconstructions, and hybrid endovascular procedures performed at centers like Toronto General Hospital, Royal Infirmary of Edinburgh, Baylor St. Luke's Medical Center, and Rikshospitalet. It has been used for coronary artery bypass grafting associated with techniques from Revascularization Trials and valve replacement influenced by innovations at St. Thomas' Hospital. The protocol’s perioperative pathways align with postoperative care models from Guy's and St Thomas' NHS Foundation Trust and randomized trial designs from Oxford University Clinical Trials Unit. Subspecialty adopters include teams involved with congenital cardiac programs at Great Ormond Street Hospital and transplant units at Papworth Hospital.
Published audits compared outcomes under the Trujillo Protocol with historical controls from Society of Thoracic Surgeons databases and multicenter registries curated by European Association for Cardio-Thoracic Surgery. Reported reductions in length of stay and transfusion requirements were contested by critiques referencing methodological issues similar to debates around studies from Cochrane Collaboration and trials overseen by Food and Drug Administration. Controversies involved interpretation of risk adjustment metrics used by National Health Service analysts and statistical comparisons akin to those in trials at Duke University Medical Center and Vanderbilt University Medical Center. Adverse-event reporting drew scrutiny in forums attended by representatives of American Medical Association and International Society for Heart and Lung Transplantation.
The Trujillo Protocol is not a device and therefore not subject to device approval by entities such as U.S. Food and Drug Administration, but institutional adoption required endorsement from hospital governance bodies including boards at Mayo Clinic, Massachusetts General Hospital, and national health authorities like Ministerio de Salud Publica de Colombia and National Health Service (England). Professional society position statements from American College of Surgeons and European Society of Anaesthesiology influenced uptake. Diffusion followed patterns observed with clinical pathways from Institute for Healthcare Improvement and accreditation criteria from Joint Commission.
Ongoing research has involved randomized and observational studies housed at Harvard Medical School, University of California, San Francisco, Universitat de Barcelona, Johns Hopkins University, and multicenter consortia coordinated through ClinicalTrials.gov. Investigations examined biomarkers and imaging endpoints drawing on collaborations with National Heart, Lung, and Blood Institute, Karolinska University Hospital, and biostatistics groups at Johns Hopkins Bloomberg School of Public Health. Innovations incorporated machine-learning risk stratification comparable to projects at Google Health and IBM Watson Health, and trials compared enhanced recovery elements similar to those evaluated by ERAS Society.
Published case series from Hospital Universitario San Vicente de Paúl and Fundación Jiménez Díaz described application in high-risk reoperative procedures, with outcome reporting discussed at conferences like American Heart Association and European Society of Cardiology congresses. A high-profile audit at Hospital Clínic de Barcelona prompted debate in editorials in journals affiliated with The Lancet, The New England Journal of Medicine, and Journal of the American Medical Association. Incident analyses referenced morbidity reviews analogous to those conducted at Royal College of Surgeons morbidity and mortality meetings and were included in training curricula at University College London Hospitals.
