Trauma service staffing is important to maintaining trauma center status. Teaching centers in the US have been grappling with resident work hour rules, and non-teaching centers have always had to deal with how to adequately staff their trauma service. What is the impact of staffing a trauma center with midlevel practitioners (MLPs) such as physician assistants and nurse practitioners?

A state designated Level I trauma center in Pennsylvania retrospectively examined the effect of adding MLPs to an existing complement of residents on their trauma service. They examined the usual outcomes, including complications, lengths of stay, ED dwell times and mortality.

Here are the more interesting factoids:

• ED dwell time decreased for trauma activations and transfers in, but it increased for trauma consults. Of note, data on dwell times suffered from inconsistent charting.
• ICU length of stay decreased significantly
• Hospital length of stay decreased somewhat but did not achieve significance
• The incidence of most complications stayed the same, but urinary tract infection decreased significantly
• There was no change in mortality

Bottom line: There is a growing body of literature showing the benefits of employing midlevel providers in trauma programs. Whereas residents may have a variable interest in the trauma service based on their career goals, MLPs are professionally dedicated to this task. This study demonstrates a creative and safe solution for managing daily clinical activity on a busy trauma service.
