Trends in ED APCT use and hospital admission over time. This figure demonstrates the annual percentage of ED encounters during which an APCT was ordered, and the percentage of encounters that resulted in hospital admission from 2001–2009. In the overall population (a), and in the analysis limited to patients with abdominal pain (b), APCT use increased (p=.005) and admission rates remained relatively stable (p=.06). When limiting the analysis to the first ED encounter (c), APCT rates were slightly higher overall, and there were significant increases in APCT use (p<.001) and admission rates (p=.002) over time. Among patients with abdominal pain who were discharged (d), there was a significant rise in APCT use (p=.005). Including inpatient APCTs performed within two days of triage (e) resulted in findings similar to the primary analysis. Trends in APCT use stratified by study site (f) demonstrates a borderline significant increase in APCT use at HUP (p=.06), and a non-significant increase (p=.34) at PPMC.
