BACKGROUND. The ''Put Prevention into Practice'' (PPIP) program was de
signed to enhance the capacity of health care providers to deliver cli
nical preventive services. This study was designed to evaluate the pro
gram's effectiveness when applied to family physicians in private prac
tice settings. METHODS. Eight Midwestern practices that had purchased
PPIP kits were identified and agreed to participate in the study. A co
mparative case study approach encompassing a variety of data collectio
n techniques was used. These techniques included participant observati
on of clinic operations and patient encounters, semistructured and key
informant interviews with physicians and staff members, chart reviews
, and structured postpatient encounter and office environment checklis
ts. Content analysis of the qualitative data and construction of the i
ndividual cases were done by consensus of the research team. RESULTS.
PPIP materials are not being used, even by the clinics that ordered th
em. Physicians already providing quality preventive services prefer th
eir existing materials to those in the PPIP kit. Sites that are underu
tilizing preventive services are unable or unwilling to independently
implement the PPIP program. CONCLUSIONS. Development of technical supp
ort may facilitate implementation of PPIP materials into those practic
es most deficient in providing preventive services. Given the diversit
y of practice environments it is unlikely that a ''one size fits all''
approach will ever be able to address the needs of all providers.
