Participation of French general practitioners in public health surveillance: a multidisciplinary approach.
OBJECTIVE
To evaluate the feasibility of a novel approach to measure compliance of sentinel general practitioners (SGPs) in sentinel public health surveillance and to determine the characteristics in the SGP's profile that can be objectively associated with their perseverance in public health surveillance.


METHODS
Prospective study of the compliance of the SGPs (compliance being defined as the length of time during which an SGP complies with a given theoretical surveillance protocol) and qualitative study of the determinants of their initial motivations (using group and face to face interviews).


METHODS
The 1970 SGPs who have participated in the Sentinel system since 1984.


METHODS
Among them, the 502 SGPs recruited since 1 July 1992 have been questioned by mailed questionnaire and 20 SGPs have been questioned during face to face semistructured interviews.


RESULTS
According to the maximum number of silences allowed by the given theoretical protocol, median compliances varied between 1.9 months (95% CI = (1.8, 2.0)) and 14.3 months (95% CI = (13.8, 15.2)). In multivariate analysis, long compliances for SGPs with a < or = 5 or > or = 20 years seniority was seen and an interest in using multimedia home servers. On the other hand, interest in local epidemiological surveys and previous experience with other surveillance networks or clinical trials were associated with short compliances. No statistical association was found between compliance and computing experience, having a medical secretary, a particular feeling of being a "public health actor", or the desire to belong to a GPs' network. A thematic analysis of interview records showed that the main motivation of the SGPs was their need to share their experiences and to self evaluate by comparison with colleagues by the means of a surveillance system that would be used as a health information system.


CONCLUSIONS
The longitudinal method used in this study was shown to be an efficient tool to monitor non-compliant SGPs with respect to given surveillance protocols. Furthermore, this approach allows the selection out of the SGPs' profile the characteristics that are associated with a longer compliance. The additional variables to be taken into account in this profile could be identified among the topics, attitudes, and experiences collected during the semistructured interviews. This work considers the question of understanding what determines the motivation of GPs to participate in public health surveillance and what are their expectations of feed back. This question is essential if information systems in general practice are to be implemented.
