Abstract

Objectives: The present study aimed to determine the prevalence of undiagnosed and undertreated hypercholesterolaemia and hypertension (HT) among ED patients and to evaluate the effects of a formal referral back to the general practitioner (GP) for further management.

Methods: This was a cross-sectional study of ED patients with follow up, if indicated. Patients aged ≥35 years, without substantial illness or communication difficulties, were enrolled. Data were collected using a researcher-administered questionnaire, a point-of-care Accutrend® Plus System machine (Roche Diagnostic Australia Pty Ltd, Castle Hill, NSW, Australia) and digital sphygmomanometer. Patients with total cholesterol (TC) ≥6.0 mmol/L and/or BP ≥140/90 were given a referral letter and advised to consult their GP. The investigators made follow-up telephone calls 5 weeks later.

Results: Of 827 presentations, 534 patients were enrolled (mean age 56.7 ± 13.3 years, 300 [56.2%] male). One hundred and eleven patients (20.7%, 95% CI 17.5-24.5) had TC ≥6.0 mmol/L. Patients with/without elevated TC differed significantly (P < 0.05) in regard to age, gender, GP ownership and attendance, and previous screening. Sixty-six patients consulted with their GP. Thirty had their TC levels retested, 18 received dietary/lifestyle advice and four had lipid-lowering medication prescribed or adjusted. Ninety-six patients (18.0%, 95% CI 14.9-21.6) had HT. Whereas 53 consulted their GP, no action was taken in 43 cases. Investigations were ordered for three and nine had antihypertensive medication prescribed or adjusted.

Conclusion: Substantial proportions of ED patients have undiagnosed and undertreated hypercholesterolaemia and/or HT. GP referral initiated interventions for many patients with hypercholesterolaemia, but fewer with HT. The ED has potential as a useful venue for the opportunistic screening of hypercholesterolaemia.
