Coding of significant comorbidities and complications for stroke in rehabilitation

Background:Comorbidities and complications of stroke have implications for level of care and hospital resources. It is critical, therefore, that hospital morbidity data accurately reflect the prevalence of these additional diagnoses.Objective:This study aimed to measure and describe the concordance between stroke clinicians/researchers and medical record coders when recording stroke and related diagnoses.Method:Diagnoses recorded prospectively, according to defined criteria by a clinical research team, were compared with the coding of stroke comorbidities and complications as per the Australian Coding Standards (ACS) from the separations of 100 inpatients from three rehabilitation facilities in South Australia. Percentage agreement, kappa coefficient, sensitivity and specificity values were calculated.Results:Kappa coefficients for agreement of prospective diagnoses with coding ranged from 0.08 to 0.819. The diagnoses with the highest agreement were stroke, aspiration pneumonia (nil cases), aphasia and dy...
