Perceived Work Performance of Patients who Experienced an Acute Coronary Syndrome Event.

The objectives of this study were to describe the perceived work performance of patients previously diagnosed with acute coronary syndrome (ACS) and to determine the relationship between patient-specific variables and perceived work performance. This cross-sectional study utilized a mailed survey to all patients discharged from a university affiliated hospital with the diagnosis of ACS during a 3-year period. Perceived work performance was measured using the Work Performance Scale (WPS). Independent variables included health status (SF-8, PCS-8, MCS-8 and EQ-5D visual analog scale), cardiac functional status (Duke activity status index), symptom count, comorbidity index, patient-perceived cardiac disease severity, medication count and compliance, job satisfaction, current employment duration, patient demographics and ACS type. Step-wise multivariate linear regression models determined the independent variables with significant association (p < 0.05) to WPS. Of 1,217 patients surveyed, 490 (40%) responded, including 158 currently working (study sample). The regression model with the highest explanatory ability (r2 = 0.29) included number of symptoms, age, perceived cardiac severity and PCS-8, with more symptoms, higher perceived severity, higher age and lower PCS-8 scores associated with lower WPS. Currently employed ACS patients report a high level of work performance. Symptom burden, perceived disease severity, age and physical function appear to be associated with perceived work performance.
