title: PP167. A process evaluation of an innovative implementation strategy of the Dutch guidelines on hypertensive disorders in pregnancy using a computerized decision support system.
abstract: BACKGROUND
  Hypertensive disorders in pregnancy remain the leading cause of maternal mortality in the Netherlands. The Dutch Society of Obstetrics and Gynecology (NVOG) has developed evidence-based guidelines on the management of hypertension in pregnancy. Previous studies showed a low adherence rate to other NVOG guidelines and a large variation in usual care in different hospitals. In the BIG CHANGE trial an innovative implementation strategy of the NVOG guidelines on hypertension using a web-based application (BOS, by Giant Soft, Leeuwarden, The Netherlands) was compared to a common strategy of professional audit and feedback. In this study a process evaluation of BOS has been done, analyzing its efficiency, barriers and formulate improvement points.
  
  
  OBJECTIVE
  Gynecologists, residents and clinical midwives from seven hospitals using BOS were asked to fill in the questionnaire.
  
  
  METHODS
  A questionnaire was developed on the following items: efficiency, barriers and improvement.
  
  
  RESULTS
  Thirty four completed questionnaires useful for analysis. 63.6% of the respondent also consulted the NVOG guideline or local protocol, mainly for confirmation of information, background information, medication. Technical problems were found in 44.1%. Positive opinions on user friendliness varied from 73.5% to 100%. No significant difference was found between the user frequency of BOS compared to the NVOG guidelines or local protocol, or between the time needed to consult them. Improvements mentioned by the respondents were mainly regarding the lay-out. Most respondents (85.3%) found it useful to make a computer based support system for other guidelines and 79.4% would also use this.
  
  
  CONCLUSIONS
  BOS is regarded suitable as an instrument for implementing guidelines and respondents find it useful to develop it for other guidelines as well. Technical problems and poor implementation are important areas of improvement.
