Scottish national bronchoscopy audit: a prospective multicentre study of 3316 cases against agreed standards. Scottish Thoracic Society.
BACKGROUND
Bronchoscopy guidelines address issues of patient and operator safety but do not give guidance on the expected yield of the procedure. Realistic standards for several outcome measures of bronchoscopy for investigating bronchial carcinoma have been derived by Scottish clinicians from a published national study. The present study describes the use of these agreed standards in prospective audit.


METHODS
All Society members in Scotland (population 5.1 million) were invited to participate. Data were collected for 1 year and coded anonymously.


METHODS
1. Supervising bronchoscopist to have completed at least 100 procedures; 2. histology to be positive in 80% of cases where tumour seen; 3. 35%-55% of bronchoscopies to reveal a diagnosis; 4. 60% of patients admitted for bronchoscopy to be day cases; 5. 80% of day case patients to be in hospital for less than 6 h; 6. 90% of male patients and 80% of female patients willing to have repeat bronchoscopy.


RESULTS
Three thousand, three hundred and sixteen bronchoscopies were performed by 45 senior pulmonologists at 22 centres. One centre reached all the standards and five centres met five standards. There was wide national variation in histological spectrum, incidence of small cell cancer ranged from 12% to 25% between centres. Participants found their own data helpful in identifying local areas for improvement.


CONCLUSIONS
Bronchcoscopy standards set locally by practising pulmonologists can be used in collaborative audit to identify areas for improving practice. Variation in histology may be accounted for by case-mix or pathology techniques.
