Children's Wisconsin Collaborative for Healthcare Delivery Science (CHDS) Projects

CHDS teams partner with Children's Wisconsin to evaluate and improve pediatric care and assessment.

Current Projects

  • Evaluating the impact of US federal economic impact payments during the pandemic on trends in child physical abuse

Completed Projects

  • Improving care options for infants with feeding restrictions
  • Assessing the Economic impact of penicillin de-labelling in the pediatric ED
  • Evaluation of At-Home Nasogastric Feeding in NICU Infant

Evaluating the Impact of US Federal Economic Impact Payments During the Pandemic on Trends in Child Physical Abuse

Overview

Research suggests an association between poverty and likelihood of child abuse. We are studying two components of child abuse data trends: 1) the impact of the Federal government stimulus checks on child abuse using an interrupted time series design, and 2) trends of child abuse during the pandemic generally, using a difference in differences model.

Anticipated Key Learnings

  • The incidence of child abuse will decrease in conjunction with the Federal government stimulus checks during 2020-2021
  • Trends of child abuse in general will be different during the COVID-19 pandemic.

Next Steps

  • Data analysis currently underway

Assessing the Economic Impact of Penicillin De-labelling in the Pediatric ED & Primary Care Clinics

Overview

Previous research and implementation by Dr. Vyles of penicillin oral challenge in the pediatric ED is helping to ascertain true penicillin allergy. As fewer patient medical records are flagged with this allergy, the costs and risk of complications from alternative antibiotics should decrease. We seek to quantify that reduction.

Key Learnings & Impact

  • There is a slight difference in the cost-savings per patient in the ED compared to the primary care patient population
  • A 95% de-labeling of penicillin allergy would have generated nearly $100,000 cost savings over an 8-year period in the pediatric ED
  • A 95% de-labeling of penicillin allergy would have generated over $525,000 cost savings over an 8-year period across 22 primary care clinics.

Results Dissemination & Next Steps

  • Results presented at the Pediatric Academic Societies & Academy Health Annual Research Meetings in 2022
