Interstitial lung disease in recent onset rheumatoid arthritis.

Interstitial lung disease (ILD) is associated with rheumatoid arthritis (RA); however, the prevalence and natural history are undefined. Our aim was to determine the prevalence of ILD associated with RA using a number of sensitive techniques in patients with joint disease of less than 2-yr duration. Patients who met ARA criteria for RA were recruited from community-based and hospital rheumatologists and assessed using the following measures: clinical, lung physiology, radiology (chest X-ray, high resolution CT [HRCT]), bronchoalveolar lavage (BAL) and 99mTc-DTPA nuclear scan. Thirty-six patients (25 female and 11 male) of joint disease duration of (mean +/- SD) 13.2 +/- 8.6 mo were studied. Abnormalities consistent with ILD were found in one or more investigations in 21 of 36 (58%), which were in lung physiology in 22%, CXR in 6%, HRCT in 33%, BAL in 52%, and 99mTc-DTPA nuclear scan in 15%. Based on the results, they were categorized as having clinically significant ILD (Group 1), abnormalities compatible with ILD, but no clinically significant ILD (Group 2) and no abnormalities compatible with ILD (Group 3). Five of 36 (14%) were in Group 1, 16 of 36 (44%) in Group 2, and 15 of 36 (42%) in Group 3. The only risk factor for the presence of abnormalities compatible with ILD was male gender (p < 0.04, Student's t test). In conclusion, changes consistent with ILD in early RA are frequent. The significance of these changes is being determined in a longitudinal study.

The cost-efficiency of incentive spirometry after abdominal surgery.

This report gives the results of a cost-efficiency analysis of a prospective longitudinal study evaluating two forms of prophylaxis against postoperative pulmonary complications in 876 patients undergoing abdominal surgery. It cost $12.19 per patient for conventional chest physiotherapy, and equivalent costs accrue when incentive spirometers are recycled and used on average 2.3 times (in the Royal Perth Hospital, incentive spirometers are recycled an average of 4.7 times). Maximum cost-containment can be achieved by carefully selecting patients for physical chest care and then instigating a programme of perioperative chest care utilizing recycled incentive spirometers. This approach does not compromise the clinical benefits of prophylactic chest care and allows physiotherapy resources to be directed toward patients with established pulmonary problems.

Incentive spirometry versus routine chest physiotherapy for prevention of pulmonary complications after abdominal surgery.

We entered 876 patients into a clinical trial aimed at preventing pulmonary complications after abdominal surgery. Patients either received conventional chest physiotherapy or were encouraged to perform maximal inspiratory manoeuvres for 5 min during each hour while awake, using an incentive spirometer. The incidence of pulmonary complications did not differ significantly between the groups: incentive spirometry 68 of 431 (15.8%, 95% CI 14.0-17.6%), and chest physiotherapy 68 of 445 (15.3%, CI 13.6-17.0%). Nor was there a difference between the groups in the incidence of positive clinical signs, pyrexia, abnormal chest radiographs, pathogens in sputum, respiratory failure (PO2 less than 60 mm Hg), or length of stay in hospital. We conclude that prophylactic incentive spirometry and chest physiotherapy are of equivalent clinical efficacy in the general management of patients undergoing abdominal surgery.
