Increased Scholarly Activity: A Benefit of 4-Year Family Medicine Residencies

The optimal length of Family Medicine Residency is unknown. As part of the American Board of Family Medicine 4-year Length of Training (LoT) pilot project, Naval Hospital Jacksonville (NHJ) maintained a dual-track 3- and 4-year Family Medicine Residency, graduating seven 4-year residents over consecutive 4 years of the LoT program. One measure of success regarding the impact of 4-year residents on program outcomes is scholarly output during residency.

Cumulative scholarly activity points are tracked for all NHJ residents. Cumulative scholarly activity points, points per year per, and raw percentile USMLE/COMLEX scores from academic years 2016-17 to 2019-20 were compared between PGY3 and PGY4 graduates using one-way ANOVA to 95% confidence with post hoc Tukey honestly significant difference pairwise comparison to evaluate pairwise significance between groups where multi-group differences were found.

During the 2016-17 through 2019-20 academic years, NHJ had 28 residents complete 3 years of training without interruption (3 Years), 11 residents complete 3 years of training interrupted by general medical officer tours (Resiterns), and 7 residents complete 4 years of training without interruption (4 Years). There were no significant differences in average raw USMLE and COMLEX scores between 3 Year (71%), Resitern (68%), and 4 Year (76%) residents (P = .335). 4-Year residents had significantly more cumulative scholarly points (103) than 3-Year residents (32.6, P < .001) and Resiterns (18.7, P < .001) and also had more cumulative scholarly points per year of residency (27.8) than 3-Year residents (9.8, P < .001) and Resiterns (7.0, P < .001).

An observed benefit of a 4-year Family Medicine Residency was a marked increase in scholarly output at this program.
