Teleconsultation for cardiac patients: a comparison between nurses and physicians: the SHL experience in Israel

The absence of randomized studies on sufficiently large patient cohorts precludes the drawing of any firm conclusions on the comparative performance between nurses and physicians in transtelephonic triage and consultations and in diagnostic and management decision-making. We conducted such a comparative study at the SHL telemedicine facility. This facility also provides face-to-face medical management for its subscribers by means of mobile intensive care units (MICUs) staffed by physicians. The outcome of calls that came between 7:00 AM and 11:00 PM throughout the study year and that were handled at random by specially trained physicians (n = 15) or nurses (n = 35) were analyzed. Of 48,707 subscribers who fulfilled the study entry criteria 25,106 used the service at least once, producing 88,103 calls (81,817 handled by nurses and 6,286 by physicians). Teleconsultations were sufficient for most of the cases (80.13%). There were no significant differences between the performance of nurses and physicians regarding demographics (age, gender) and medical diagnoses of the applicants. The nurses' performance and decisions were comparable to those of physicians with respect to teleconsultations, medically justified dispatches of an MICU, repeated calls to the center and mortality during the week after the index call, although the duration of the physicians' telephone consultations was longer. Delegation of equal authority to nurses and physicians in triage and consultation in telecardiology results in equivalent and highly satisfactory medical care in a system in which subscribers receive service orchestrated from a single center of telecommunications.
