INTRODUCTION Hospital readmissions have become a quality metric for both hospital systems and individual surgeons. The medical literature is replete with studies describing readmission rates and factors contributing to readmissions following surgical procedures. Relatively little, however, has been done to define potential solutions to these problems. Over the past decade there has been a movement toward the development of multidisciplinary colorectal centers at high volume children's hospitals. We hypothesized that the development of a colorectal center at our children's hospital decreased readmissions in our colorectal surgery population. MATERIALS AND METHODS A retrospective review was performed including all patients with the diagnosis of anorectal malformation (ARM) or Hirschsprung disease (HD) at our institution between the years of 2005-2017. Patient level outcomes were compared between the cohort treated prior to (2005-2010) and the cohort treated after the development of the colorectal center (2012-2017). RESULTS A total of 354 patients were identified. One hundred seventy-eight patients (113 ARM, 65 HD) were treated prior to and 176 patients (110 ARM, 66 HD) were treated after the development of the colorectal center. Forty-five (25.3%) patients underwent neonatal repair prior to development of the center compared to 15 (8.5%) after. 111 (62.4%) patients underwent colostomy prior to the colorectal center comparted to 95 (54%) after. The rate of readmission within 120 days of discharge in the early group was 63% compared to 52% in those managed in the multidisciplinary colorectal center (p = 0.04). Conversely, the rate of emergency room visits increased from 8.4% to 27.3% (p = 0.01). The decrease in readmission rates was more pronounced in the ARM group, while the HD cohort had similar readmission rates before and after the establishment of the center. Multivariate logistic regression revealed an odds ratio of 0.59 (95% CI 0.37-0.92) for readmission following the development of the multidisciplinary colorectal center. DISCUSSION The development of a multidisciplinary colorectal center at our institution was associated with decreased hospital readmissions, but an increase in emergency department resource utilization. These findings suggest improved efficiency in patient care with the implementation of a multispecialty, patient centered approach while also identifying areas of focus for future quality improvement initiatives.
