Conjoint analysis is a technique relatively new to the evaluation of health care services in the UK. The technique uses data generated from questionnaires. This paper addresses the issue of response-ordering effects that may result from the ordering of dimensions of benefit within a question. Two questionnaires were given to 216 hospital consultants as part of a priority setting exercise. These were identical other than the ordering of the dimensions within each question. The regression analysis was segmented according to questionnaire type and the coefficients of the segmentation were tested for statistically significant differences. The results show no evidence of ordering effects.

In the past year, several publications have reported on aspects of health services research in regard to musculoskeletal disorders. Utilization studies in the elderly have shown that an effective procedure such as hip arthroplasty may be underused in this population. As well, surgical complications in these patients appear to vary according to the number of procedures performed in a hospital, with high-volume hospitals showing better outcomes. Studies of practice patterns show variations among rheumatologists in the treatment of various rheumatic diseases. Practice variations between physician groups, in particular, rheumatologists versus primary care providers, have also been reported. Several studies show that primary care physicians may have some difficulties in diagnosing common rheumatic disorders. There is some evidence as well that rheumatologists may provide better care for some conditions, such as rheumatoid arthritis. These findings have major implications for restrictions to patient access to specialist care by health organizations. A variety of clinical practice guidelines have been developed and tested, most aimed at general practitioners. Physician compliance with guidelines continues to be low for most implementation strategies. Multidisciplinary programs for the treatment of rheumatoid arthritis appear to have a somewhat beneficial effect. Programs based only on patient education appear to have short-term gains, and longer-term effects are diluted because of noncompliant behaviors.
