Risk factors, causes, and rates associated with hospital readmission after pediatric neck mass surgery

Background: To understand rates, risk factors, and costs associated with hospital readmission in pediatric patients who underwent neck mass excision. Methods: This was a retrospective review of the Nationwide Readmissions Database (NRD) between 2010 and 2014 of select neck mass procedures, defined as affecting the following: thyroid, salivary gland, cervical lymph nodes, branchial cleft, thymus, and head and neck vessels. We analyzed rates and causes of 30-day readmissions using univariate and multivariate logistic regression. Results: There were a total of 11,824 weighted cases identified with a 30-day readmission rate of 9.0% and a mean age of 9.5 years old. The sex distribution of patients undergoing neck mass procedures was 55.8% female and 44.2% male. The most common cause of readmission was associated with a comorbid condition likely unrelated to the neck mass procedure (53%). The most common procedure-related readmission causes were associated with a postoperative neck mass (14.4%), wound (13%), and infection (6.5%). In the multivariate model, number of procedures>5 (OR: 2.11, 95% CI: 1.28-3.49), number of chronic conditions>1 (OR: 2.33, 95% CI: 1.16-4.66), length of hospital stay of>7 days (OR: 2.43, 95% CI: 1.48-0.3.98), and cervical lymph node procedure (OR:2.61, 95% CI: 1.47-4.63) were associated with higher readmission risk. Conclusion: Readmission after surgery for pediatric neck masses is relatively common, with an average of 9.0%. Risk factors associated with readmission include length of initial hospital stay, number of chronic conditions, number of procedures performed, and undergoing a cervical lymph node procedure.
