Who Consults Us and Why? An Evaluation of Medicine Consult/Comanagement Services at Academic Medical Centers
Although general medicine consultation is an integral component of inpatient medical care and a requirement of internal medicine training, little is known about current consultative practice. We used a cross-sectional, prospective survey design to examine current practices at 11 academic medical centers over four 2-week periods from July 2014 through July 2015. Out of 11 consult services, 4 had comanagement agreements with surgical services, primarily with orthopedic surgery. We collected data regarding 1,264 consultation requests. Most requests (82.2%) originated from surgical services, with most requests originating from either orthopedic surgery (44.4%) or neurosurgery (11.6%). The most common reason for consultation at sites with a consult and comanagement service was medical management/comanagement (23.3%) and at sites with a consult-only service was preoperative evaluation (16.4%). On average, consultants addressed more than 2 reasons per encounter. Many of these reasons were unidentified by the consulting service. Learners on these services should perform comprehensive evaluations to identify potentially unidentified issues.

All survey responses and free-text RFC entries were independently reviewed and categorized by 2 authors (E.W. and M.S.). New categories were created if needed. If reviewers disagreed, a third reviewer (C.M.) reviewed the RFC. The research consortium reviewed the final list of categories and entries.
We calculated descriptive statistics using SAS version 9.3 (SAS Institute, Inc., Cary, North Carolina). Each analysis used complete responses for each survey component. We separately analyzed services with and without comanagement components. The study was approved by UTHSA’s Institutional Review Board.
RESULTS
A total of 11 AMCs that represent 9 academic affiliations participated in this study (Table 1). Of the 11 AMCs, 7 were public nonprofit, 3 were private nonprofit, and 1 was a Veterans Health Administration facility. Out of the 11 AMCs, 9 sites included residents on the consult service, and the rotation was required at 6 of the sites. Most sites with residents had a formal curriculum that ranged from curated articles to online modules. Out of the 11 services, 4 were consult and comanagement services. All 4 co-managed orthopedic patients, and 1 also included other patients.
Data for 1,264 patient encounters with 2,778 RFCs were collected. A total of 1,218 of the surveys (96.4%) were fully completed, and only 5 surveys were missing data for multiple questions. A total of 7 sites adhered to the planned protocol. Among the sites, 1 site had 1 incomplete collection period, 1 site missed 1 collection period, and 1 site missed 2 collection periods.
Most consultations (87.1%) were requested during the day. Many patients (55.9%) were initially seen by residents, and 32.4% of the patients were initially seen by an attending. Respondents reported communicating verbally with the requesting team in 93.9% of instances. Among the patients, 7.8% were transferred to medicine following initial consultation. This percentage was higher (10.2%) in services without comanagement.
The average number of new consults per day per site was 2.24. The range for individual sites was 1.36-3.48. The maximum number of new consults in 1 day was 10. All sites had at least 1 day without new consults. The mean number of RFCs per encounter was 2.20 (median 2, range 1-13). In 226 of 360 encounters in which comanagement was an RFC, the respondent enumerated the other specific RFCs addressed. In these encounters, the mean number of RFCs (in addition to comanagement) was 3.02.
Most requests (82.2%) originated from surgical services. Among all surgical services, orthopedic surgery requested the highest number of consultations (67.5% for services with a comanagement component; 28.5% for services without) and 81.2% of the 360 comanagement encounters. Refer to Supplemental Table 1 for detailed information on the services that requested consultation.
The most common RFC was comanagement (13.0% across the entire study; 23.3% for services with a comanagement component; Table 2). For services without comanagement, preoperative evaluation was the most common RFC (16.4%). Other frequent RFCs across the entire study included blood pressure management (8.9%), glycemic management (7.2%), and renal failure (3.9%). Additional (unstated) RFCs were addressed in 944 patients (34.0%), and blood pressure management was the most common additional RFC.
Respondents indicated that 54.9% of RFCs were clinical topics that are “often” or “always” encountered in IM inpatient services. In 11.8% of encounters, the RFC was “rarely” or “never” encountered; the most common RFCs in such encounters were comanagement (53.4%), preoperative evaluation (17.4%), and transfer to medicine (5.4%).
