Factors associated with surgical site infection in myocardial revascularization: a retrospective longitudinal study.
Amanda Gubert Pereira, Juliana Martins Lopes, Lorena Cristina Silva Pereira and 5 others
PMID 38088713WHAT IT FOUND
33.5% of myocardial revascularization patients developed surgical site infection.
Body temperature outside 36 to 36.5°C, invasive devices, and anticipated critical surgical events were associated with higher risk. Checklist adherence score did not track with infection.
Key findings
01The study included 266 medical records of patients, and 89 (33.5%) of the participants developed surgical site infection after cardiac surgery.
02Body temperature outside the range of 36 to 36.5°C, invasive devices, and anticipated critical surgical events were associated with higher risk of infection.
03The total surgical checklist adherence score did not have a statistically significant relationship with infection.

What it does not show
The study looked backward at medical records at a single hospital, so it can show associations but not prove that any factor caused infection. The authors state that medical records lacked detailed information about the surgical anesthetic procedure. The ASA score was not fully documented in 4 cases (1.6%). Patients were selected non-probabilistically, so the sample may not represent all myocardial revascularization patients. Because it was not an intervention study, it did not test whether keeping body temperature within 36 to 36.5°C, limiting invasive devices, or planning for critical events prevents infection.
The easy way to misread this
Do not conclude that surgical checklists do not help. The study found no significant relationship between total checklist adherence score and infection in a retrospective record sample, but it did not test checklist implementation as an intervention.
