Background. There is widespread agreement among pediatric educators that co
ntinuity (following a panel of patients on a first contact basis for all th
eir health care) is an important part of the education of pediatricians.
Objective. To measure continuity in a pediatric residency practice and to c
ompare this continuity with 2 nearby private general pediatric group practi
ces. We also examined measures of continuity suggested in the literature.
Design. Visit data were obtained from the practice billing system for a res
ident continuity practice and 2 nearby private practices for the 3-year per
iod from July 1, 1992, to June 30, 1995. Visit data used were restricted to
patients seen in the office of the practices during regular office hours.
Continuity was measured using 5 different indices: 1) the usual provider of
care index, visits by the usual clinician/total visits, 2) continuity for
patient, the average proportion of visits that an individual patient was se
en by his or her own physician, 3) continuity for physician (PHY), the aver
age proportion of visits that an individual physician saw his or her own pa
tients, 4) Continuity of Care Index (COC), and 5) the Modified, Modified Co
ntinuity Index. During the period examined, pediatric residents were presen
t in the continuity practice for 1 half-day each week. The resident continu
ity practice (RCP) had 57 residents and saw 3386 patients for 18 955 visits
. Private practice 1 (PP1) had 4 pediatricians who saw 4968 patients for 33
537 visits. Private practice 2 (PP2) had 5 pediatricians who saw 11 953 pa
tients for 75 778 visits.
Results. For all visit types, continuity in the RCP was not as high as in t
he private practices, PHY-RCP versus PP1, PP2; 53% versus 70%, 77%. However
, continuity in RCP was greater than 50% for all measures except the COC in
dex, which precipitously decreases as the number of clinicians seen increas
es. Examining continuity for health maintenance visits (PHY-RCP, PP2 vs PP1
; 96%, 96% vs 82%) RCP was equal to the best of the private practices. The
percentage of patients not seen for a health maintenance visit during the s
tudy period was lowest in the resident practice (RCP/PP1/PP2, 15/22/30).
Conclusion. Although continuity for all visits in this RCP was less than in
private practice, it was surprisingly high, considering the limited time r
esidents spend in clinic. In a particularly important area for continuity,
health maintenance visits, continuity was identical to one and superior to
the other private practice.
