[Potential cost reductions for the National Health Service through a telecardiology service dedicated to general practice physicians].
BACKGROUND
Rising health care costs resulted in increasing pressure on the health care system and stimulated new strategies for improving the efficiency of care. A telecardiology service provides a useful support to general practitioners in the management of cardiac patients and contributes to the optimization of health care costs in terms of appropriateness of hospital admission and diagnostic testing. The aim of our study was to evaluate the reduction in the number of referrals to the Emergency Department and to cardiological evaluation resulting from the employment of a telecardiology service by general practitioners.


METHODS
Eight hundred and ninety-one consecutive calls arrived to the receiving station of the telecardiology service were analyzed. One hundred and fifty general practitioners received a portable electrocardiographer (Card-Guard 7100, Rehovot, Israel) transferring, by a mobile or fixed telephone, a 12-lead ECG to a receiving station, where a cardiologist was available for reporting and for interactive teleconsultation. At the onset of the phone call, a question was asked to the general practitioner: "What would you have done without the telecardiology service?". The possible answers were: "No actions"; "Referral to the Emergency Department"; "Cardiological consultancy"; "Further investigations". Then we collected the history, risk factors, symptoms and therapy of the patients; the general practitioner sent the ECG tracing by phone.


RESULTS
Eight hundred and ninety-one patients were enrolled (402 males, 489 females, mean age 59 +/- 19 years); 465 (52%) patients were symptomatic; 36.4% had no evidence of previous cardiac disease, 35.1% had systemic hypertension, 10.6% had ischemic cardiac disease, 3.7% had atrial fibrillation, and 11.9% other diseases. ECG was normal in 55%. The general practitioners would have sent to the Emergency Department 106 patients (11.9%), and requested further investigations in 717 patients (80.5%). The cardiologist of the telecardiology service solved the problems of the general practitioners in 657 cases (73.7%), sent 56 patients (6.3%) to the Emergency Department, and asked for further investigations in 178 patients (20%), with a reduction of 47% of Emergency Department admission (p < 0.001) and of 95% of further investigations (p < 0.0001) respectively. The cost analysis showed a reduction, between the two modalities, varying from Itl 22,760,000 and Itl 140,060,000 for 891 calls.


CONCLUSIONS
Telemedicine is a useful tool for the support of general practitioners' daily activity, with a possible cost reduction due to increased appropriateness of hospital admission and of diagnostic testing.
