Clinical practice guidelines: barriers to durability after effective early implementation.

摘要

BACKGROUND: Clinical practice guidelines in general (General-CPG) may reduce variation in clinician performance and improve patient outcomes. Short-term evaluation is now routine, but demonstration of early successful implementation does not necessarily ensure longer-term effectiveness. AIM: To assess adherence to chronic obstructive pulmonary disease (COPD)-CPG recommendations at the Royal Melbourne Hospital (RMH), 2 years after successful implementation. To identify barriers to sustained success of General-CPG. METHODS: A multi-faceted evaluation was performed to document: (i) current adherence to COPD management recommendations (medical record audit); (ii) awareness of attitudes towards and barriers for the use of COPD-CPG and General-CPG (staff survey, focus groups and key informant interviews) and (iii) access to and quality of available General-CPG (internet review and random sample General-CPG evaluation. RESULTS: Adherence to COPD-CPG recommendations was highly variable. Adherence was higher inthe Emergency Department than the general wards and for specific therapeutic recommendations. It was lower for non-pharmacological therapy and for recommendations relating to processes of care. Most health professionals were in favour of General-CPG. Barriers to use of General-CPG were in keeping with previous literature reports. Organizational issues including high levels of staff turnover and lack of integration of General-CPG into hospital quality frameworks were highlighted as major barriers. Hospital intranet access and presentation of General-CPG identified lack of consistency in terminology and presentation. CONCLUSION: Short-term effectiveness of COPD-CPG implementation did not ensure sustained success. Departmental organizational behaviours and organizational system barriers are major factors influencing durability.
