Abstract

Background
Individuals with low socio-economic status (SES) have disproportionate rates of cardio- vascular disease (CVD) but poorer engagement with preventative health. This study aimed to compare characteristics of individuals with and without hyperlipidaemia and describe their health behaviours.
Methods
A mixed-methods study between January-December 2022. Patients aged ≥40 years using the ambulance service with blood pressure of ≥140/90 had their total cholesterol measured using a point of care device. Data including blood pressure, smoking status, National Early Warning Score 2 (NEWS2) and clinical frailty scale (CFS) were analysed.
Results
Of 203 patients (59% female, mean age 65.7 years), 115 (56.7%) had total cholesterol ≥5.1mmol/L. Thirty patients (14.8%) sought treatment and received either statins (n=9; 4.4%), dietary modification (n=7; 3.4%) or no further intervention (n=14; 6.9%), whilst 85 patients (41.9%) took no further action. Lower CFS (OR 0.53 [0.31-0.93]) and higher total cholesterol (OR 2.07 [1.03 – 2.76]) predicted seeking further management. SES was not associated with hyperlipidaemia or likelihood of seeking further management which was dictated by competing co-morbidity, poor health literacy and digital divide.
Conclusions
Undiagnosed hyperlipidaemia exists in patients using the ambulance service, irrespective of SES. Individual and healthcare system factors prevent engagement in cholesterol lowering behaviours.
