A pilot study of tele-ophthalmology outreach services to primary care.

We have begun a randomized study of tele-ophthalmology. General practitioners in two participating health centres in the Negev region of Israel, serving a local population of 40,000, were invited to participate. The study group consisted of 50 consecutive patients attending the general eye outpatient clinic and 50 consecutive patients suffering from various retinal diseases attending a hospital outpatient clinic. The initial assessment was carried out via the tele-ophthalmology system. There was then a face-to-face re-examination of the same patients, in randomized order, by the same ophthalmologist on the same day, at an outpatient ophthalmology clinic.

Towards a comprehensive telecardiology monitoring centre for community-based services.

In a pilot study of primary-care telecardiology, 2563 consultations were carried out over 18 months. Following teleconsultation, 2076 patients (81%) were found to be suitable for management entirely by the general practitioner, without the need for referral to hospital. The system identified 487 patients (19%) with cardiac problems who required either admission to hospital or outpatient assessment. There was a resultant saving of referrals to hospital accident and emergency departments. Extension of the telecardiology service to include tele-echocardiography may result in faster access to diagnosis and better management of patients in heart failure, improving patients' quality of life and reducing hospitalization.

Telecardiology: supporting the decision-making process in general practice.

To assess the initial phase of a telecardiology diagnostic service for general practitioners (GPs), we provided 93 GPs in 26 health centres with direct telephone access to a cardiologist, and equipped them with hand-held, automatic standard 12-lead electrocardiogram (ECG) transmitters for on-line cardiac consultations and ECG interpretation in their daily practice. Clinical details, reason for consultation and the ECG signal were transmitted from the GPs' practices or the patients' homes. A consultation followed and a full report, including ECG print-out, was then sent to the GP. During an 18-month study period, 2563 consultations were carried out. The system allowed the identification of 479 patients (19%) with urgent cardiac problems and the remaining 2084 (81%) in whom admission or outpatient investigation was unnecessary. Following the study, we distributed a questionnaire asking the GPs to rate the quality, define the use and consider the benefit of the service to their daily practice. We conclude that a telecardiology diagnosis and ECG interpretation service is simple, reliable and efficacious in routine primary care. It offers instant access to cardiac assessment and supports the decision-making process of GPs. A preliminary cost comparison with a conventional referral indicated that a teleconsultation was substantially cheaper. We expect that the future incorporation of teleechocardiography would expand the scope of telecardiology even further and allow comprehensive cardiology consultations.

Reduced in-hospital mortality from acute myocardial infarction with general adoption of thrombolytic treatment in the North West Thames health region 1979-1991.

OBJECTIVE: To determine the impact of studies of thrombolytic treatment in acute myocardial infarction on inhospital mortality. DESIGN: Retrospective study. SETTING: All 21 major hospitals in the North West Thames health region. PATIENTS: 63,903 patients with acute myocardial infarction. STUDY PERIOD: 1979-1991. MAIN OUTCOME MEASURES: in-hospital mortality. RESULTS: Overall mortality decreased by 5.2% from 25.4% to 20.2% (P < 0.0001) (95% confidence interval (CI) 3.4 to 6.6). Male mortality decreased by 6.5% from 22.3% to 15.8% (P < 0.0001) (95% CI 4.8 to 8.4); female mortality decreased by 4.3% from 32.6% to 28.3% (P < 0.01) (95% CI 1.3 to 7.4). Reductions in mortality occurred in all age and sex groups but were greater in younger patients. Logistic regression analysis of death rates showed that the odds ratio of death in 1991 compared with that in 1979 was 0.75 (95% CI 0.69 to 0.82). After allowing for the effects of age and sex, this odds ratio became 0.54 (95% CI 0.49 to 0.59), as more elderly patients were treated in 1991. Purchase of streptokinase increased 31-fold from 116 doses in 1983 to 3554 doses in 1991. There was a pronounced negative association between annual purchases of streptokinase and mortality (Kendall's rank correlation = -0.86, P = 0.003). Changes in clinical practice resulted in the saving of the lives of an estimated 600 patients with acute myocardial infarction in 1991. This extrapolates to an annual saving of 10,500 lives in the United Kingdom. CONCLUSIONS: In the past few years thrombolytic treatment has been widely adopted for the management of acute myocardial infarction. This has been paralleled by a substantial reduction in in-hospital mortality.
