CHICAGO – A care model that uses hospitalists to comanage vascular surgery patients cut myocardial infarction rates by more than half and reduced hospital stays by about 12%, according to results of a study of the hospitalist comanagement model from Loyola University Chicago, Maywood, Ill., presented at the annual meeting of the Midwestern Vascular Surgery Society.
“Hospitalist comanagement was associated with decreased length of stay without affecting readmission for patients undergoing amputation, embolectomy, and infected graft,” said Kaavya Adam, a third-year medical student at Loyola University Chicago. “In the overall population, there was a reduction in cases of MI, 30-day readmissions, and overall length of stay.”
In 2014, Loyola implemented a program that used 11 hospitalists to rotate through the vascular surgery service. The hospitalists call on any patient who stays more than 24 hours on the non-ICU floors. Adam said hospitalist duties include evaluating patient comorbidities, adjusting medication, talking with family about medical management, seeing patients on the day of surgery, ordering preoperative labs, and meeting with the anesthesiology and vascular surgery teams.
The study compared outcomes in 866 patients admitted during 2007-2013, before the comanagement model was put into place, and 572 admitted during 2014-2017.
Rates of diabetes, hypertension, chronic kidney disease, coronary artery disease, hyperlipidemia, and malnutrition were similar between the groups. However, the pre-comanagement group had significantly higher rates of ischemic pain (27.8% vs. 10.7%), gangrene (21.3% vs. 13.6%) and ulceration (30.6% vs. 21.9%), while the comanaged group had significantly higher rates of claudication (34.3% vs. 13.2%). The statistical analysis accounted for these variations, Adam said.
“We did find significant results for the reduction in the odds of MI at 30 days; there was a 61% reduction,” he said.
The reduction in hospital stay was even more pronounced for patients with complex cases, Adam said. In amputation, the length of stay was reduced by 3.77 days (P = .01); in embolectomy, by 7.35 (P = .004); and in infected graft, by 8.35 (P = .007).
Continuing research will evaluate the cost effectiveness of the hospitalist model and define a comanagement model that is most beneficial, Mr. Adam said. He had no relevant financial disclosures.
