Purpose. To determine the proportion of regional primary care physicia
ns who would attend grand rounds on preventive services and their inte
rest in and use of free follow-up enabling and reinforcing assistance
to implement changes in their practice routines. Method. From January
to July 1992 grand rounds on early detection of cancer were offered by
Dartmouth Medical School at 38 acute care community hospitals in New
Hampshire and Vermont. The target audience of 679 family physicians an
d general internists was identified through state medical society and
hospital attending lists. The hour-long grand rounds program described
preventive service guidelines and an office system that promoted thei
r implementation. Follow up practice support with planning, office sta
ff training, and materials were offered to augment the effects of the
grand rounds. Attendance was determined by sign-in documents. In addit
ion, all attendees were asked to complete a survey regarding practice
and personal characteristics and interest in follow-up assistance. Sta
tistical comparisons were made using chi-square and Fisher's exact tes
ts. Results. In all, 261 family medicine physicians and general intern
ists (38.4%) attended. Certain categories of physicians were more like
ly to have attended: internists, those younger than 55 years, and phys
icians on the staffs of hospitals located in small towns. Assistance w
as requested by 70.1% of the attendees; many requested more than one t
ype of assistance. Physicians from hospitals in smaller towns were mor
e likely to show interest in followup assistance and use it when offer
ed. Conclusion. Many of the grand rounds attendees were receptive to f
ollow-up assistance that could improve the preventive services they pr
ovided. Most hospitals offer grand rounds, and many organizations have
interest in and resources for helping physicians provide high-quality
care. Future research should establish the best linkage to the actual
care provided in practices and explore the relevance of similar appro
aches to clinical areas beyond prevention.
