Evaluation of an open access echocardiography service in the Netherlands: a mixed methods study of indications, outcomes, patient management and trends

Background: In our region (Eastern South Limburg, The Netherlands) an open access echocardiography service started in 2002. It was the first service of this kind in The Netherlands. Our study aims were: (1) to evaluate demand for the service, participation, indications, echocardiography outcomes, and management by the general practitioner (GP); (2) to analyse changes in indications and outcomes over the years. Methods: (1) Data from GP request forms, echocardiography reports and a retrospective GP questionnaire on management (response rate 83%) of 625 consecutive patients (Dec. 2002-March 2007) were analysed cross-sectionally. (2) For the analysis of changes over the years, data from GP request forms and echocardiography reports of the first and last 250 patients that visited the service between Dec. 2002 and Feb. 2008 (n = 1001) were compared. Results: The echocardiography service was used by 81% of the regional GPs. On average, a GP referred one patient per year to the service. Intended indications for the service were dyspnoea (32%), cardiac murmur (59%), and peripheral oedema (17%). Of the other indications (22%), one-third was for evaluation of suspected left ventricular hypertrophy (LVH). Expected outcomes were left ventricular dysfunction (LVD) (43%, predominantly diastolic) and valve disease (25%). We also found a high proportion of LVH (50%). Only 24% of all echocardiograms showed no relevant disease. The GP followed the cardiologist's advice to refer the patient for further evaluation in 71%. In recent patients, more echocardiography requests were done for 'cardiac murmur' and 'other' indications, but less for 'dyspnoea'. The proportions of patients with LVD, LVH and valve disease decreased and the proportion of patients with no relevant disease increased. The number of advices by the cardiologists increased. Conclusion: Overall, GPs used the open access echocardiography service efficiently (i. e. with a high chance of finding relevant pathology), but efficiency decreased slightly over the years. To meet the needs of the GPs, indications might be widened with 'suspicion LVH'. Further specification of the indications for open access echocardiography-by defining a stepwise diagnostic approach including ECG and (NT-pro)BNP-might improve the service

A pilot quality improvement intervention in patients with diabetes and hypertension in primary care settings of Cyprus

Methods. In a two-arm non-randomized controlled study in primary care centres in Cyprus, all patients with hypertension (HTN) and diabetes (n = 539) were invited. In one urban and one rural centre, a quality improvement programme was implemented; two other centres (one urban and one rural) served as control practices. The intervention mainly consisted of the introduction of clinical disease management guidelines and an electronic medical record system. The primary outcome measurement was improvement of specific clinical indicators for HTN and diabetes. Patients' satisfaction was evaluated using the European Task Force on Patient Evaluations of General Practice (EUROPEP) questionnaire over an 18-month follow-up period. Results. Five hundred and four patients completed the study, 278 patients in the intervention practices and 226 patients in the control practices. Mean results for blood pressure, total cholesterol and low density lipoprotein-cholesterol and three annual performance measures (urine protein testing, dilated eye and foot examination) had improved at 18-month follow-up in the intervention as compared to the control group. There was no improvement of HbA1c levels. Patients' satisfaction improved in the intervention practices (improvement of 10/23 EUROPEP items) but decreased in the control group (decline of 20/23 items). Conclusions. A pilot multifaceted quality improvement intervention programme for patients with diabetes and HTN implemented in primary care settings in Cyprus showed promising results. Future studies need to involve a broader number of practices and patient populations
