Introduction

Fever Without apparent Source (FWS)- body temperature ≧ 38.0 degrees Celsius- no apparent source found after evaluation

Serious Bacterial Infection (SBI)1 – 36 months Sophia Children’s Hospital ( 2003.9.1 – 2005.12.31 )

Time spent at the ED Identified SBI

1744 Febrile children, 1-36 months

1399 Eligible

683 CDSS - Registered

390 Patients with FWS

172 High risk-score & randomized( Informed consent n = 164 )

375 chronic co-morbidity

716 not registered

293 Fever with a clear source

218 Low risk-score

74 Order laboratory tests 90 Routine evaluation by physician

Page 8: Randomized Trial of a Clinical Decision Support System

Methods

Randomization ( 1-1000 )- odd : intervention group (order laboratory tests)- even : control group

laboratory tests- complete blood count (CBC)- C-reactive protein (CRP)

Page 8

Page 9: Randomized Trial of a Clinical Decision Support System

Measurements

ED time- arrival time ~ departure time

Serious Bacterial Infection (SBI) - culture or radiographically

Conclusion

Time constraintsED nurses were aware the decision ruleFWS registration rate is relatively highLaboratory tests affected diagnostic testing

The prediction rules need adjustmentReduce false high-riskIncreasing the risk-score threshold
