Understanding the information needs of general practitioners managing a rare genetic disorder (osteogenesis imperfecta).

Abstract

Background: Lack of adequate knowledge is a common problem in medicine, but is a particular problem in a rapidly advancing field like genetics. This study uses the example of a rare genetic disorder (osteogenesis imperfecta) to understand the information needs of primary care physicians (GPs).

Objectives: To determine whether a knowledge gap is recognised, how GPs currently attempt to overcome it, and what features of an information resource are preferred by GPs.

Methods: GPs of children affected by osteogenesis imperfecta in and around Greater London were interviewed, using both questionnaire-based semi-structured interview and a qualitatively analysed open-ended discussion. Consultations in both primary and tertiary care settings over a 5-year period were compared.

Results: Problems due to osteogenesis imperfecta were presented to GPs in about one third of consultations with these patients. GPs reported finding such patients difficult to manage due to lack of knowledge. Knowledge from tertiary sources, which was authoritative, accessible and relevant, was preferred, particularly when reasoning was explained. Primary literature and clinical guidelines were not favoured.

Conclusions: Empirical evidence supports and elaborates theoretical models for provision of clinically useful information. A model for improved information services using authoritative web-based information linked to electronic patient records is suggested.
