Direct access exercise electrocardiography: a new service that improves the management of suspected ischaemic heart disease in the community

Open access echocardiography has diagnostic yield similar to outpatient echocardiography and is highly rated by general practitioners and patients

BACKGROUND

Open access echocardiography is widely available to General Practitioners (GP). There is little data comparing the proportion of echocardiographic studies which are abnormal in open access series with that in hospital outpatient practice. This study compares the diagnostic yield from echocardiograms performed for similar indications by open access and hospital out patient requested groups and assesses the attitudes of GPs and patients to open access echocardiography.

METHODS

The reports of 151 consecutive patients who had open access echocardiograms were analysed using predefined criteria for an abnormal study. The reports of 100 consecutive patients who had a new outpatient requested echocardiograms for similar indications were used as the control group. The attitudes of GPs and patients to the open access service were also assessed.

RESULTS

Fifty seven percent of patients in the open access group and 51% in the hospital requested group had abnormal studies (p>0.05). 92% of GPs who responded to the questionnaire thought the report was easy to understand while 69% thought it led to a change in patient management. 74% said a clinic referral would have been made without this service and 79% preferred a management strategy to be included in the report. 90% of patients had been informed of the result by their GP.

CONCLUSIONS

Open access echocardiography has a diagnostic yield similar to echocardiograms requested on new hospital outpatients in a district general hospital setting. GPs and patients report high levels of satisfaction with this service.

Rapid access chest pain clinics--can they be justified?

Rapid access chest pain clinics are expanding across the country with marked resource implications despite a paucity of data regarding their efficacy. Early assessment of patients in this manner potentially delays review of patients referred via the traditional route. We conducted a prospective observational study of patients referred with chest pain to the Cardiology Outpatient Department over a four-week period in a District General Hospital to compare demographics and outcomes in patients referred to the rapid access with those referred to the general cardiology clinics. There were no significant differences in baseline demographics, exercise test result or clinic outcome. Both populations were low risk. Discussion is needed between primary and secondary care to achieve a consensus as to the purpose of a rapid access system and how best to utilise the service appropriately. Further studies are required to assess the efficacy and health economics of this system.

Technician run open access exercise electrocardiography

OBJECTIVE

To evaluate the safety, efficacy, and feasibility of the technician run open access exercise electrocardiography service at Freeman Hospital.

DESIGN

Questionnaire analysis of the responses of the general practitioners of randomly selected patients who used the service.

SETTING

A tertiary care cardiac centre, providing an open access service to general practitioners in the community.

PATIENTS

269 patients randomly selected from 552 who underwent open access exercise electrocardiography over a 2.5 year period.

OUTCOME MEASURES

Utilisation of service: the reasons for referral, whether the service was optimally used by the general practitioners, and its effect on their management practice; effect on number of cardiology referrals; benefit to the patients; safety, efficacy, and feasibility of a technician run service; general practitioners' assessment of the service.

RESULTS

147 of 178 general practitioners (82.6%) responded to the questionnaire, on 247 of 269 patients (91. 8%). General practitioners used the service for diagnosing ischaemic heart disease in 72.5% of cases, for prognostic purposes in 17.8%, or both in 5.3%. In 197 cases (79.8%), the general practitioners felt that the service had changed the way they managed their patients. The exercise test was positive in 90 patients (36.5%) and identified 38 as at high risk. The service was effective in optimising the cardiology service by reducing referrals by 47%.

CONCLUSIONS

The service was used by general practitioners primarily for diagnosing ischaemic heart disease and not so often for prognosis. The utilisation of the service was optimal as assessed by the high positivity rate. The service meets its primary objective of assisting general practitioners in the management of patients with suspected ischaemic heart disease, and may have helped to optimise resources by reducing the number of referrals to cardiologists. It has helped prioritize patient management and may have benefited high risk patients by facilitating rapid identification and referral. It can be run safely and effectively by trained technicians.

Open access echocardiography in management of heart failure in the community

OBJECTIVE

To assess the value of an open access echocardiography service.

DESIGN

Study of new open access service for general practitioners, who were invited to refer patients taking diuretics for suspected heart failure, untreated patients with symptoms of possible heart failure, and asymptomatic patients with risk factors for left ventricular systolic dysfunction.

SETTING

Regional cardiology centre.

SUBJECTS

259 consecutive patients.

MAIN OUTCOME MEASURES

Presence or absence of left ventricular systolic dysfunction and consequent changes in clinical management.

RESULTS

119 treated patients, 99 untreated patients, and nine asymptomatic patients were referred over five months. 32 were considered to be inappropriately referred. Among the treated patients, 31 had impaired left ventricular systolic function and five had valvular disease; angiotensin converting enzyme inhibitors were recommended for 34 of these patients. In addition, 53 were thought not to need diuretics. Eight untreated patients had impaired systolic function and six valvular disease.

CONCLUSIONS

The service was well used by general practitioners and led to advice to change management in more than two thirds of patients.

General practitioners' requirements from a hospital cardiology department

The requirements of 500 general practitioners from a hospital department of cardiology were sought and assessed from a questionnaire. One hundred and twenty two general practitioners caring for 766,384 patients responded. The most important inpatient service requirement was that cardiologists should be responsible for the management of patients with acute myocardial infarction and other acute cardiac conditions. The expertise and reputation of the consultant cardiologist and the waiting time for an appointment were the two most important outpatient service requirements. The least important aspect was the time patients waited in clinic to see a doctor. Fundholders considered price of outpatient consultations to be unimportant. Waiting times for cardiac catheterisation and non-invasive cardiac investigations together with the quality of the investigation equipment and the technical staff were all considered to be important requirements. Most general practitioners wanted protocols for managing common cardiac conditions. The majority wanted an open access investigation service to reduce outpatient waiting times. Those who did not want an open access service explained that they would not be confident in interpreting the results or deciding subsequent management. An understanding of the requirements of general practitioners is helpful in planning and developing hospital services.
