LAUSR

Objectives The frequency of lumbar punctures (LPs) has declined across US children's hospitals over the past decade, potentially decreasing procedural learning opportunities for pediatric resident trainees. Our study sought to determine whether the proportion of successful LPs performed by our pediatric residents has significantly changed over time. Methods This study is a single-center retrospective study to evaluate our pediatric resident LP success. We evaluated our primary outcome, proportion of overall LP success over time, using linear regression. We similarly used linear regression for proportion of successful resident-associated LPs over time. We calculated the median number of LPs of all pediatric residents during the study period. Results We analyzed 3143 LPs from April 2012 to December 2019. Both the overall number of LPs performed and the proportion of LPs that were successful have not significantly changed over an 8-year period (P > 0.05, P > 0.05). Similarly, the number of our resident-associated LPs and the proportion of successful resident-associated LPs have not changed over the study period (P > 0.05, P > 0.05). Our pediatric residents performed a median of 3 LPs (interquartile range: 2–4) in the pediatric emergency department (PED) over residency. Conclusions Despite national trends showing decreased LP rates at pediatric hospitals, we demonstrated stable proportions of LPs and success by our pediatric residents. Pediatric residents perform a relatively low number of LPs in the PED setting alone. Future research is needed to demonstrate whether these overall low numbers in the PED translate to procedural competency after residency graduation.
