    Abstract:
    BACKGROUND AND OBJECTIVE: Starting in 2004 the patient budget in Germany will be calculated according to the Diagnosis Related Group (DRG) system, by which system the monetary reward of a unit will be directly related to the quality of documentation e. g. diagnosis and procedures. The aim of this study was to compare the quality of documentation by a medical documentation assistant (MDA) with the usual practice of documentation by the ward physician (WP). Additionally, the effect of introducing a completely changed organizational process was tested. METHODS: In a prospective study on the ward of a gastroenterology unit two different approaches of medical documentation were compared. In a first six-month period diagnosis and procedures were encoded by WP. In the following six months an MDA was introduced and involved in the encoding process. RESULTS: In the first six months 221 patients (mean age 55 +/- 16,2 years, 55,7 % males) were evaluated, whereas in the following six months 305 patients (mean age 53 +/- 15,4 years, 59,9 % males) were included. The introduction of an MDA improved medical documentation and economical reference numbers: with an increase of diagnosis per case to 7,43 (in first six months 5,53), patient complexity and comorbidity level (PCCL) to 2,5 (in first six months 2,13), case-mix index to 1,04 (in first six months 0,98). Additionally the medial hospitalization time decreased from 11,2 to 8,1 days. The average daily reimbursement increased in the MDA group from 423 Euro to 603 Euro. This was calculated on the basis of a basic case factor of 2900 Euro. CONCLUSION: Introduction of an MDA in a gastroenterology ward increases the quality of documentation and results in an improved presentation of DRG-relevant efforts with a better reimbursement of medical costs.
