Can a screening tool safely identify low risk cardiac patients to be transported with primary care flight paramedics?

We aimed to determine the rate of adverse events during interfacility transport of cardiac patients identified as low risk by a consensus-derived screening tool and transported by primary care flight paramedics (PCP(f)).

We conducted a health records review of adult patients diagnosed with a cardiac condition who were identified as low risk by the screening tool and transported by PCP(f). We excluded patients transported by an advanced care crew, those accompanied by a clinical escort from hospital, and those transported from a scene call, by rotary wing or ground vehicle. We recorded patient and transportation parameters using a piloted-standardized collection tool. We defined adverse events during transport a priori. We report descriptive statistics using mean (standard deviation), [range], (percentage).

We included 400 patients: mean age 66.9 years old, 66.5% male. Mean transport duration was 136.2 (74.9) minutes. Most common comorbidities were hypertension (50.3%) and coronary artery disease (39.5%). Most transports originated out of Northern Ontario and were for cardiac catheterization (61.8%) or coronary artery bypass grafting (26.8%). Overall, the adverse event rate was low (0.3%), with no serious event such as cardiac arrest, death, or airway intervention.

A screening tool can identify cardiac patients at low risk for clinical deterioration during air-medical transport. We believe patients screened with this tool can be transported safely by a PCP(f) crew, leading to potentially significant resource savings.
