Effectiveness of Traumatic Brain Injury management guideline introduction in Hungary.

AIM The aim of this study was to describe the impact of the Traumatic Brain Injury management guideline introduction in Hungary. MATERIAL AND METHODS Hospital discharge records (HDR) including age, gender, codes of interventions applied, ICD codes of diagnosed disorders of patients admitted between 01/01/2004 and 31/12/2010 with diagnosis of intracranial injury (S06 by ICD10) from every inpatient institution in Hungary were collected from the database of National Health Insurance Fund (NHIF). The Case Fatality Rates (CFR) for one week, one month and six months were calculated for the periods before and after the guideline introduction. The change of CFRs was applied as indicators for change of clinical quality elicited by guideline. RESULTS The centers together at one week, one month and six months had pre-guideline introduction CFRs of 23.4 %, 37.7 % and 47.5 % and post-guideline introduction CFRs of 22.1%, 39.1%, and 50.0% respectively. The secondary institutions together at one week, one month and six months had pre-guideline introduction CFRs of 21.5 %, 34.8 % and 46.3 % and post-guideline introduction CFRs of 21.9%, 37.0%, and 48.9% respectively. None of the CFRs showed significant change. CONCLUSION The effectiveness of TBI management guideline adaptation in Hungary is poor. Without supportive financing and external auditing system, guideline introduction alone cannot achieve standard clinical practice and a reduction in CFR.
