    Abstract

    Introduction - Acute Coronary Syndrome (ACS) is the most common cardiovasculardiagnosis requiring hospital admission worldwide and in the UK. It is associatedwith substantial mortality and healthcare burden. Given the current five dayworking pattern in the UK, we hypothesise a significant variation in the outcomesof patients admitted with ACS during the standard working hours compared without of hours and weekends.Methods: Anonymous data of adult patients aged ≥18 with all types of ACS admittedto 7 hospitals between 2000 and 2013 was obtained and processed usingthe ACALM (Algorithm for Co-morbidity, Associations, Length of stay and Mortality)study protocol. ACALM uses the ICD-10 and OPCS-4 coding systems toidentify patients and the methodology has been used and published widely. Analyseswere performed comparing mortality and length of hospital stay betweenadmissions according to the day of the weeks and core working hours (0900 to1700 Monday to Friday) and out of these hours.Results: Of 929465 adult patient population there were 25294 patients with ACS.Mean age 67 years; Male 64.2%. Over the study period, 38.2% of the patientsdied after ACS during their follow-up period. However, patients admitted on Saturdayor Sunday had significantly higher values of 43.3% and 39.9% respectively.Patients admitted outside of the normal working hours had a value of 39.1% comparedwith 36.5% for patients admitted during working hours. The mean length ofhospital stay (LOS) was significantly higher for patient admitted on Saturday andSunday and outside of core working hours (p<0.05).Table 1.

These disparities furtherfuel the argument for 24/7 specialist care in the UK.
