Which hospital-acquired conditions matter the most in trauma? An evidence-based approach for prioritizing trauma program improvement.
The purpose of this study was to quantify and compare the impacts of six different hospital-acquired conditions (HACs) on early clinical outcomes and resource utilization in hospitalized trauma patients. The researchers included 529,856 adult patients from the 2013 to 2016 American College of Surgeons Trauma Quality Improvement Program Participant Use Data Files with 5 days or longer of hospitalization and had an Injury Severity Score of 9 or higher. The study found the incidences of HACs were: pneumonia, 5.2%; urinary tract infection, 3.4%; venous thromboembolism, 3.3%; surgical site infection, 1.3%; pressure ulcer, 1.3%; and central line-associated blood stream infection, 0.2%. The HAC of pneumonia demonstrated the largest association with in-hospital outcomes and resource utilization. The researchers reported that prevention of pneumonia within the study group would have resulted in estimated reductions of: 22.1% for end organ dysfunction, 8.7% for prolonged hospitalization, 7.8% for mortality, 7.1% for prolonged intensive care unit stay, and 6.8% for need for mechanical ventilation. The researchers concluded that pneumonia prevention should be a priority activity in program improvement efforts.

De-escalation of empiric antibiotics following negative cultures in hospitalized patients with pneumonia: rates and outcomes.
This study assessed antibiotic de-escalation practices across hospitals and their associations with outcomes in hospitalized patients diagnosed with pneumonia with negative cultures. The authors included 14,170 adults admitted with pneumonia in 2010-2015 to 164 US hospitals if they had negative blood and/or respiratory cultures and received both anti-MRSA and antipseudomonal agents other than quinolones. If empiric drugs were stopped on day 4 while continuing another antibiotic it was defined at de-escalation. Patients were propensity adjusted for de-escalation and compared on in-hospital 14-day mortality, late deterioration with ICU transfer, length-of-stay (LOS) and costs. Thirteen percent (1924 patients) had both initial empiric drugs stopped by hospital day 4. De-escalation rates at hospitals ranged from 2-35% and the established rate quartiles were not significantly associated with outcomes. Even at hospitals in the top quartile of de-escalation, the de-escalation rates were lower than 50%.
