Listserv use enhances quality and safety in multisite quality improvement efforts.

A listserv is an e-mail group to which people subscribe based upon common interests. We used a retrospective study to examine the relationship between listserv use and team success for health care quality improvement efforts. We hypothesized high listserv use would be associated with team success. Eighty-seven Department of Veterans Affairs teams participated in facilitated quality improvement efforts to address three areas: improving safety in high-hazard areas, improving the disability evaluation process, and reducing falls and related injuries. We coded messages sent to the listserv according to sender (faculty or participant), team, and content. We correlated the volume of messages sent per team with team success and with team and facility characteristics. Teams with high listserv contributions were more likely to complete their first test of change, report facility use of nonpunitive methods of investigating medical incidents, and report their information systems were useful. We found a negative correlation between listserv contribution and the number of face-to-face meetings and a physician as an active team member, but we found no relationship between team success and listserv contribution. Team listserv contribution was not associated with team success in multisite quality improvement efforts. Successful teams may be accessing information on the listserv but not sending a message to indicate use.
