Impact on readmission rates and mortality of a chronic obstructive pulmonary disease inpatient management guideline.

AIMS: Chronic obstructive pulmonary disease (COPD) is a common condition associated with considerable morbidity, mortality and hospital admissions. However, published COPD management guidelines have major limitations and lack practical summaries. We aimed to optimally develop, implement, and evaluate a multidisciplinary COPD inpatient management 'ACCORD' guideline, including prompts for comprehensive day one assessments through to a discharge criteria checklist. METHOD: Two intervention and two control public teaching hospitals in Adelaide, South Australia, took part, with pre-intervention (721 COPD admissions over 7 months) and intervention phases (509 COPD admissions over 7 months). During the intervention stage the ACCORD guideline was placed in the case notes on the day of admission or soon after. Readmissions were categorized as either emergency or elective and compared between the study arms, as were mortality and potential confounders (age, gender, number of comorbidities), with Poisson regression analysis. RESULTS: Of case notes of eligible COPD patients, 60% had the ACCORD guideline placed, of which 76% had evidence of use as judged by completion of guideline entry and tick boxes. The ACCORD guideline was associated with an increase in elective admissions and a reduction in emergency admissions in the intervention group in relation to the control group (P < 0.01), with no difference in overall admissions or death rates. CONCLUSIONS: The ACCORD guideline was associated with a shift from emergency admissions to more planned elective care, suggesting more proactive care of health problems, but without overall reduction in admissions.

Systematic assessment of clinical practice guidelines for the management of chronic obstructive pulmonary disease.

OBJECTIVE: To systematically evaluate the quality of the development of guidelines for the management of chronic obstructive pulmonary disease (COPD). METHODOLOGY: MEDLINE and Excerpta Medica search for published guidelines, followed by independent evaluation by two reviewers, according to previously reported guideline development quality criteria, on a three-point scale. RESULTS: Five national COPD guidelines and two international COPD guidelines were retrieved. Reviewers demonstrated good inter-observer agreement in assessing the 10 combined guideline development criteria for the seven guidelines [kappa = 0.66]. Guidelines were only partly multi-disciplinary with little or no consumer input, were up to 48 pages in length, and often lacked practical summaries or management flow charts which could have facilitated retrieval of key management recommendations. Almost all the papers were based upon a consensus approach, rather than evidence based, and methods of resolution of differences of opinion were not stated. Patient outcomes, ethical and medico-legal implications were not addressed and six of the guidelines were sponsored directly or indirectly by a single drug company. CONCLUSIONS: In spite of COPD guidelines being reported by major national bodies for over a decade now, most fail to meet important criteria for high-quality guideline development, and evaluation of clinical impact remains undetermined.
