Introduction:
Primary care referrals to specialty physicians once relied upon the medical skill of
the specialist, the quality of past communication, and previous consultative
experiences. As health systems vertically integrate, patterns of specialty physician
referral designation are not known.
Methods:
This cross-sectional study from a patient-centered medical home (PCMH) evaluated the
proportion of referrals with named specialists. All outpatient specialty referrals from
the PCMH between July and December of 2014 were eligible for inclusion, and 410 patients
were randomly selected for chart review. The outcome of interest was specialty physician
designation. Other variables of interest included PCMH provider experience, the reason
for referral, and time to specialty visit. Univariate analysis was performed with Fisher
exact tests.
Results:
Of 410 specialty referrals, 43.7% were made to medical specialties, 41.7% to surgical
specialties, and 14.6% to ancillary specialties. Resident physicians placed 224
referrals (54.6%), faculty physicians ordered 155 (37.8%), and advanced practice
providers ordered 31 (7.6%). Only 11.2% of the specialty referral orders designated a
specific physician. No differences appeared in the reason for referral, the referral
destination, the proportion of visits scheduled and attended, or the time to schedule
between those referrals with and without specialty physician designation. Faculty
physicians identified a specific specialist in 21.4% of referrals compared to residents
doing so in 4.9% (
P
< .0001).
Conclusion:
Patient-centered medical home referrals named a specific specialty physician
infrequently, suggesting a shift from the historical reliance on the individual
characteristics of the specialist in the referral process.
