About
The investigators aim to show the feasibility and medicoeconomic impact of implementing a clinical screening and response system for the early detection of perioperative cardiac complications in high-risk patients.
Specifically, the investigators aim to: 1) evaluate the feasibility of implementation of a PMI-screening; 2) evaluate the medicoeconomic impact of implementing a PMI-screening; 3) identify barriers to implementation; 4) generate data for a future randomized controlled trial on outcomes by exploring opportunities to improve care following PMI, the occurrence and timing of major adverse cardiac events (MACE), and the treatment effect associated with PMI-screening.
Full description
Background: Perioperative myocardial infarction/injury (PMI) is increasingly recognised as frequent, but often undiagnosed and untreated contributor to mortality following noncardiac surgery. Due to differences in pathophysiology and perioperative anaesthesia and analgesia, most PMI do not cause typical ischemic symptoms and are therefore missed in routine clinical practice. Active surveillance using cardiac troponin (cTn) is now guideline-recommended for the early detection of PMI to possibly improve outcome1. Given substantial concerns regarding the feasibility and health economic impact of implementing such a strategy, it is not yet widely applied.
Aim: to show feasibility of implementation as well as health economic impact of an active surveillance for the early detection of PMI in high-risk patients.
Methodology: in this observational before-after study the investigators will enrol patients at high cardiovascular risk undergoing noncardiac surgery before and after implementation of a PMI screening. Patients in the pre-implementation phase will receive standard of care, while in the post-implementation phase patients receive a PMI-screening, consisting of a preoperative and two postoperative measurements of high-sensitivity cTn (hs-cTn) and a cardiology consultation will be done in case of detection of a PMI. Patient data, resource utilisation, and PMI-aetiology will be collected. Interviews with key stakeholders will identify barriers to implementation. One-year follow-up will be conducted to evaluate occurrence of death, MACE, and safety endpoints.
Potential significance: This study will generate important insights regarding the feasibility, safety and the health economic impact of implementing an active surveillance for the early detection of PMI.
