ABSTRACT
The present study assessed the impact of computerised spirometry interpretation expert support on the diagnostic achievements of general practitioners (GPs), and on GPs' decision making in diagnosing chronic respiratory disease. A cluster-randomised controlled trial was performed in 78 GPs who each completed 10 standardised paper case descriptions. Intervention consisted of support for GPs' spirometry interpretation either by an expert system (expert support group) or by sham information (control group). Agreement of GPs' diagnoses was compared with an expert panel judgement, which served as the primary outcome. Secondary outcomes were: additional diagnostic test rates; width of differential diagnosis; certainty of diagnosis; estimated severity of disease; referral rate; and medication or nonmedication changes. Effects were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). There were no differences between the expert support and control groups in the agreement between GPs and expert panel diagnosis of chronic obstructive pulmonary disease (OR (95% CI) 1.08 (0.70-1.66)), asthma (1.13 (0.70-1.80)), and absence of respiratory disease (1.32 (0.61-2.86)). A higher rate of additional diagnostic tests was observed in the expert support group (2.5 (1.17-5.35)). Computerised spirometry expert support had no detectable benefit on general practitioners' diagnostic achievements and the decision-making process when diagnosing chronic respiratory disease.

Tonsillectomy, in 90% of cases combined with adenoidectomy, is one of the most frequently carried out operations on children in the Netherlands: in 1998 there were 33,471 operations in children aged 0-14 years. This high frequency is in stark contrast to the scientific basis for the efficacy of this intervention. A meta-analysis carried out recently revealed just one good study. The lack of scientifically based clinical guidelines, partly explains the large international and regional differences in the number of operations carried out. In the Netherlands only 35% of the children operated on satisfy one of the criteria for which the effectiveness of (adeno)tonsillectomy has been established: frequent recurrent tonsillitis or obstructive sleep apnoea. A project has been started in the Netherlands to further study the effectiveness of this intervention, the results of which must contribute to a more thoroughly substantiated indication.
