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.

Trends in hospital readmission for asthma: has the Australian National Asthma Campaign had an effect?

OBJECTIVES: To describe patterns of hospital readmission for asthma in South Australia from 1989 to 1996, in relation to implementation of the National Asthma Campaign. DESIGN AND SETTING: A comparison of hospital admissions in South Australia of patients aged between one year and 49 years for three conditions: asthma (or respiratory failure with asthma as an underlying condition) and two control conditions--diabetes and epilepsy. Individuals were identified by Medicare number and date of birth. OUTCOME MEASURES: Hospital readmission within 28 days and within one year. RESULTS: Overall, by 1996, there was a statistically significant decline in the risk of readmission for asthma within 28 days of 18% and within one year of 17% compared with 1989 readmission rates. There were no reductions in the risk of readmission for diabetes or epilepsy, suggesting that the decline in risk of readmission for asthma was greater than the underlying effects of general changes in hospital casemix. CONCLUSIONS: The decline in risk of readmission may reflect changes in asthma severity or improved management practices. However, hospital readmission rates still remain high, and to further reduce readmissions for asthma there is a need to identify factors related to presentation for asthma at accident and emergency departments.

Randomised controlled trial of general practice based asthma clinics.

OBJECTIVE: To compare the effects on asthma morbidity of asthma clinics based in general practice with standard general practice care. DESIGN AND SETTING: A randomised controlled trial in eight general practices. Patients, general practitioners and outcomes assessors were not blinded to treatment allocation. PARTICIPANTS: 195 patients with asthma aged 5-64 years; 191 completed the trial. INTERVENTION: Three asthma clinic sessions over six months involving nurse counselling, education about asthma management, spirometry and consultation with the general practitioner. MAIN OUTCOME MEASURES: Patients reporting days lost from work or school, number of days lost, the presence of morning or nocturnal asthma symptoms, use of an action plan, medication use, current smoking, hospitalisation, and emergency visits. RESULTS: Asthma clinics were associated with a greater reduction in nocturnal symptoms, an increase in the ownership of peak flow meters and an increase in the number of patients commencing or resuming smoking. Both control and intervention groups showed similar improvement in days lost from work or school, the presence of symptoms, use of an action plan and taking reliever medication. CONCLUSION: Our study does not show that asthma clinics are more effective than standard general practice care in reducing asthma morbidity. It is uncertain how much of the improvement in outcomes was due to the asthma clinic, the influence of the study itself upon patients and practitioners, or other factors, such as the tendency for a patient's asthma management to improve over time.

Rehospitalisation for asthma within 12 months: unequal rates on the basis of gender in two hospitals.

BACKGROUND: High asthma morbidity has been reported in certain demographic groups in geographical areas of low socioeconomic status (SES). AIM AND METHODS: We tested for an ecological association between the gender of people being frequently hospitalised for asthma and the SES of the area in which they lived, using a cross-sectional study. RESULTS: Women represented 75% of the readmission population at The Queen Elizabeth Hospital (TQEH--low SES hospital) and 55% at Modbury Hospital (moderate-high SES hospital). Women at TQEH were significantly more likely to have one readmission within 12 months and over 30 times more likely to have two or more readmissions than women at Modbury Hospital. CONCLUSION: The ecological association observed in this study needs to be confirmed elsewhere in Australia.
