Was the Pediatric Emergency Department or Pediatric Urgent Care Center Setting More Affected by the Fall, 2009 H1N1 Influenza Outbreak? G. Conners, MD, MPH, MBA; T. Hartman, MHA; M. Fowler, MD; L. Schroeder, MD; T. Tryon, MD Children’s Mercy Hospitals & Clinics, Kansas City, MO
Background • The H1N1 influenza outbreak of Fall, 2009 stressed the resources of our pediatric emergency department (PED) and two pediatric urgent care centers (PUCCs). • As the leaders of the Division that manages both areas, we had to make PED versus PUCC resource allocation decisions based on guesswork, rather than data.
Background • We sought to learn from our experience, in order to determine whether the PED or the PUCC setting had been more affected, to help guide future decision-making. • Our areas of focus for this analysis: • overall volumes (# patients registering) • rates of elopement (either left before seen or during evaluation)
Setting • Free-standing, academic children’s hospital in Kansas City, MO: • Main hospital: ~70,000 annual visit PED • Northland: multiple pediatric sub-specialty clinics in North K.C., including a noon-10 PM PUCC (~23,000 / yr) • South: multiple pediatric sub-specialty clinics / inpatient beds in Overland Park, KS, including a 24/7/365 PUCC (~55,000 / yr)
Methods • Fall, 2009 H1N1 influenza outbreak period: 8/1/09 – 11/15/09 • Using an administrative database, we compared patient data during this period with those of the same dates in 2008: • Patients who registered* (volume) • Rates of patients who eloped (either left before seen or during evaluation) • We combined data from the two PUCC sites *We adjusted (increased) the Fall, 2008 Northland PUCC volume by 8.6%, to account for increased service hours in Fall, 2009 versus Fall, 2008 (adjustment determined by comparing 12/09-3/10 with 12/08-3/09)
Methods • We statistically compared overall patient volumes using chi-square test, and changes in elopement rates using Poisson regression. • Our IRB deemed this a quality improvement project, not subject to IRB approval.
Results: Volume PUCC increase > PED increase p<.0001
Results: Elopement Rates PUCC rate increase > PED rate increase p<.0001
Results • Both the PED and PUCC settings experienced substantial surges in patient volume and elopement rates during the Fall, 2009 H1N1 influenza outbreak.
Results: Volume • The PUCC setting had both a larger absolute increase (5057 versus 3230) and relative increase (26.0% versus 17.4%) in patient volume than did the PED during the Fall, 2009 H1N1 influenza outbreak.
Results: Elopement Rates • The PUCC setting had a larger elopement rate increase (172% for PUCC versus 58% for PED) and nearly as large an absolute elopement increase (552 for PUCC versus 598 for PED) than did the PED during the Fall, 2009 H1N1 influenza outbreak.
Discussion • Q: Was the PED or the PUCC setting more affected by the Fall, 2009 H1N1 influenza outbreak? • A: The PUCC!
Discussion • This suggests that, when allocating resources between the PED and the PUCC during a large-scale influenza (or similar) outbreak, the PUCC should receive a substantial, and perhaps a majority, share.
Two Major Limitations • We have measured and compared the quantity, not the quality, of the effects of the Fall, 2009 H1N1 outbreak on PED and the PUCC. Related issues: • who came to each setting for care • acuity differences • who eloped, and why? , etc.
Two Major Limitations • Inherent limitations of our research design: before-after study using an administrative database. Related issues: • changes in other factors between 2008 / 2009? • accuracy of administrative data? • the baseline adjustment we made, etc.
Conclusions • Both the PED and PUCC were very affected by the Fall, 2009 H1N1 influenza outbreak. • In terms of volume of patients seen and increase in elopement rates, the PUCC setting was more affected than the PED setting. • Although not the whole story, given the limitations, this information will be useful when allocating resources in future, similar situations.
