AbstractThe elderly individuals are the most rapidly growing cohort within the US population, and a corresponding increase is being seen in elderly trauma patients. Elderly patients are more likely to have a hospital length of stay (LOS) in excess of 10 days. They account for 60% of total ICU days. Length of stay is frequently used as a proxy measure for improvement in injury outcomes, changes in quality of care, and hospital outcomes. Patient care protocols are typically created from evidence-based guidelines that serve to reduce variation in care from patient to patient. Patient care protocols have been found to positively impact patient care with reduced duration of mechanical ventilation, shorter LOS in the ICU and shorter overall hospitalization time, reduced mortality, and reduced health care costs. The following study was designed to assess the impact of the implementation of 4 patient care protocols within an elderly trauma population. We hypothesized that the implementation of these protocols would have a beneficial impact on patient care that could be measured by a decrease in hospital LOS. An archival, retrospective pretest/posttest study was performed on elderly trauma patients. The new protocols helped guide practical changes in care that resulted in a 32% decrease in LOS for our elderly trauma patients which exceeds the 25% decrease found in other studies. Additionally, the "Other" category for each variable was less frequently used in the post-protocol phase than in the pre-protocol phase, suggesting a spillover effect on the level of detail recorded in the patient chart. With less variation in practices in the post-protocol phase, Injury Severity score, and admission systolic blood pressure emerged as significant predictors of LOS.
