# Interdepartmental Commensality: A Strategy for Increased Interdepartmental Collaboration

## TL;DR

Sharing meals between university departments can boost collaboration and familiarity among faculty.

## Contribution

This study introduces interdepartmental commensality as a novel strategy to foster collaboration.

## Key findings

- Participants showed significantly increased familiarity with colleagues after dinners.
- Willingness to engage in academic discussions improved significantly.
- Anticipated future collaborations increased substantially post-intervention.

## Abstract

The concept of commensality, the act of eating together, is as old as humanity and has been extensively explored in the social sciences and humanities. We sought to assess whether an interdepartmental commensality program would improve cross-departmental familiarity, willingness to engage in scholarly discussions, and enhance collaborative efforts.

A program was established to arrange dinners for emergency department (ED) faculty with six other departments, after which participants were surveyed about their thoughts on the dinner’s impact. Our primary outcome measure was change in perceived familiarity with interdepartmental colleagues. Secondary outcomes included willingness to engage in academic discussion and perceived likelihood of future collaboration. A program was established to arrange dinners between the ED and six other departments (obstetrics and gynecology, neurology, psychiatry, internal medicine, otolaryngology, and ophthalmology), followed by a post-event survey.

A total of 55 of 81 participants responded to the survey (response rate 67.9%). We found significant increases in familiarity with colleagues (2 pre- to 4/5 post-intervention, P < .001), willingness to discuss academic issues (4 to 5/5, P < .001), and anticipated collaborations (2 to 5/5, P < .001).

An interdepartmental commensality program initiated by an institution’s department of emergency medicine can potentially improve interdepartmental collaboration, familiarity, and discussions.
