  • Background: PCR technology can be used for precise detection of infectious agents and improves antibiotic stewardship through: Accelerated de-escalation of therapy Rapid identification of pathogens Detection of resistance genes. In our center, basic respiratory Panel detect 11 targets and cost $100 while Complete panel detect 31 targets and cost $230.The purpose of the study is to improve utilization of these panel testing in a large community hospital.

    Methods:

    Retrospective chart review of all patients with an order for a complete or basic panel and excluding Patients discharged or deceased prior to result reporting or insufficient specimen quantity to perform. Each patient was evaluated for appropriate respiratory panel collection site and antibiotic regimen changes within 48 hours of results. The preintervention period conducted from 10/2015- 12/2015, evaluated how respiratory panels were being utilized in antibiotic decision-making. Three primary interventions were enacted: Eliminated nasal swabs as a source option for respiratory panels in the clinical information system, restricted complete panel ordering to ID physicians and Eliminated PCR ordering options from all order sets. The postintervention period conducted from 5/2016 – 8/2016, re-evaluated the utilization and costs of respiratory panels.

    Results: 270 tests ordered preintervention (13% basic and 87% complete) and 196 postintervention (84% basic and 16% complete), nasal swab was done in 78% in preintervention vs 8% in postintervention, action was taken in 51 vs 44 in pre-vs post intervention. cost in preintervention period was 57,420 in preintervention vs 23,660 in post intervension. No difference between ID vs non-ID specialist in utilization of PCR.

    Conclusion:

    Nasal swab collections for PCR decreased post-intervention from 78% to 8%. Appropriate sources for PCR specimen, such as sputum, were utilized during the post-intervention period. Post-intervention utilization of the panel results was comparable to pre-intervention period. Elimination of PCR respiratory panels from order sets and restrictions of complete respiratory panel ordering to ID physicians resulted in $33,760 saved.
