Abstract
Importance: Older patients who undergo surgery may benefit from geriatrician comanagement. It is unclear whether other internal medicine (IM) physician involvement improves outcomes for adults who undergo surgery.
Objective: To evaluate the association of IM physician involvement with clinical and health system outcomes compared with usual surgical care among adults who undergo surgery.
Data Sources: MEDLINE, Embase, CINAHL, and CENTRAL databases were searched for studies published in English from database inception to April 2, 2019.
Study Selection: Prospective randomized or nonrandomized clinical studies comparing IM physician consultation or comanagement with usual surgical care were selected by consensus of 2 reviewers.
Data Extraction and Synthesis: Data were extracted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline by 2 authors independently. Intervention characteristics were described using existing indicators. Risk of bias was assessed using Risk of Bias 2.0 and Risk of Bias in Nonrandomized Studies of Interventions tools. Studies were pooled when appropriate in meta-analysis using random-effects models. Prespecified subgroups included IM physician-only vs multidisciplinary team interventions and patients undergoing elective vs emergency procedures.
Main Outcomes and Measures: The prespecified primary outcome was length of stay; other outcomes included 30-day readmissions, inpatient mortality, medical complications, functional outcomes, and costs.
Results: Of 6027 records screened, 14 studies (with 1 randomized clinical trial) involving 35 800 patients (13 142 [36.7%] in intervention groups) were eligible for inclusion. Interventions varied substantially among studies and settings; most interventions described comanagement by a hospitalist or internist; 7 (50%) included a multidisciplinary team, and 9 (64%) studied predominantly patients who had elective procedures. Risk of bias in 10 studies (71%) was serious. Meta-analysis showed no significant association with length of stay (mean difference, -1.02 days; 95% CI, -2.09 to 0.04 days; P = .06) or mortality (odds ratio, 0.79; 95% CI, 0.56 to 1.11; P = .18), but multidisciplinary team involvement was associated with significant reduction in length of stay (mean difference, -2.03 days; 95% CI, -4.05 to -0.01 days; P = .05) and mortality (odds ratio, 0.67; 95% CI, 0.51 to 0.88; P = .004). There was no difference in 30-day readmissions (odds ratio, 0.89; 95% CI, 0.68 to 1.16; P = .39). Data could not be pooled for complications or costs. Only 1 study (7%) reported functional outcomes.
Conclusions and Relevance: The findings of this study suggest that IM physician comanagement that includes multidisciplinary team involvement may be associated with reduced length of stay and mortality in adults undergoing surgery. Evidence was low quality, and well-designed prospective studies are still needed.
