Clinical documentation in medical records can be broadly defined as any notation made by medical practitioners and other health professionals relating to a patient’s symptoms, past history, test results or treatments provided during a clinical encounter.Clinical documentation is critically linked to accurate clinical coding and accurate generation of the diagnosis related group (DRG) resulting in appropriate remuneration to the hospital in a case-mix based funding model (Cheng et al. 2009). With the exception of DRGs ending in ‘A’ or ‘Z’, a proportionately higher level of funding may be generated for complications and comorbidities that have been treated, investigated or have required increased clinical care but have not been coded within an admitted patient episode. These complications/comorbidities have the potential to change the Episode Clinical Complexity Score (ECCS) (previously known as Patient Clinical Complexity Level (PCCL)) which influences the acuity of the DRG and resulting reimbursement. The ECCS is a measure of the cumulative effect of a patient’s complications and comorbidities and is calculated for each episode of care using the Diagnosis Complexity Level (DCL) value assigned to each diagnosis code (including principal diagnosis) as a complexity weight.Simple checklists or proformas have been shown to improve the accuracy of the principal diagnosis and procedure code resulting in a higher remuneration for the organisation (Clement et al. 2013; Naran et al. 2014; Murphy et al. 2017). Such checklists are completed by the medical team responsible for the patient in hospital. This task is usually delegated to the most junior member of the team. The clinical coding department at the Mater Health Services have developed such checklists for various specialties. The uptake of the use of these checklists during the inpatient stay is variable.This study aims to confirm the increased remuneration achieved by using checklists and to compare the remuneration generated by a junior medical person as compared to a senior doctor using these lists to help with chart reviews.
