Utilizing triage rates to improve ICU admission guidelines of elderly rib fracture patients.

BACKGROUND: Elderly rib fracture patients are generally admitted to an ICU which may result in overutilization of scarce resources. We hypothesized that this practice results in significant overtriage. METHODS: Retrospective study of patients over age 70 with acute rib fracture(s) as sole indication for ICU admission. Primary outcomes were adverse events (intubation, pneumonia, death), which we classified as meriting ICU admission. We utilized Cribari matrices to calculate triage rates. RESULTS: 101 patients met study criteria. 12% had adverse events occurring on average at day 5. Our undertriage rate was 6% and overtriage rate 87%. The 72 overtriaged patients utilized 295 total ICU days. Evaluating guideline modification, ≥3 fractures appears optimal. Changing to this would have liberated 50 ICU days with 3% undertriage. CONCLUSION: Elderly patients with small numbers of rib fractures are overtriaged to ICUs. Modifying guidelines to ≥3 rib fractures will improve resource utilization and save ICU beds.

Incidence of general surgical procedures in adult patients on extracorporeal membrane oxygenation.

PURPOSE: Extracorporeal membrane oxygenation use may predispose patients to developing conditions that require either consultation with a general surgeon or a general surgical procedure. We aimed to evaluate the incidence and outcomes of adult extracorporeal membrane oxygenation patients who underwent general surgical procedure. METHODS: This was a single institution retrospective study of adult extracorporeal membrane oxygenation patients from 2012 to 2015. Outcomes were compared between patients who underwent general surgical procedure with those that did not. RESULTS: Of the 115 patients, 54 (46.9%) required a general surgeon while 42 (36.5%) required a general surgical procedure. No significant differences were observed in mortality (35.7% vs. 46.6%; p = 0.256) and extracorporeal membrane oxygenation-related complications (45.7% vs. 32.5%; p = 0.175). Patients with general surgical procedure had longer extracorporeal membrane oxygenation duration (13 vs. 5 days; p < 0.0001), longer length of stay (36 vs. 15 days; p = 0.0005), more wound infections (19.05% vs. 5.5%; p = 0.029), more urinary tract infections (38.1% vs. 10.96%; p = 0.0006), and more pulmonary emboli (19.05% vs. 5.48%; p = 0.029). In general surgical procedure patients, no difference in bleeding complications was observed regardless of anti-coagulation status (29.4% vs. 16%; p = 0.44). CONCLUSION: Common general surgical procedures are safe and feasible in adult extracorporeal membrane oxygenation patients. Duration of extracorporeal membrane oxygenation was longer for patients requiring general surgical procedure. Despite the common use of anticoagulants, there was no increase in bleeding events in general surgical procedure patients.

Incidence of nosocomial infections in adult patients undergoing extracorporeal membrane oxygenation.

INTRODUCTION: Critically ill patients requiring extracorporeal membrane oxygenation (ECMO) are at increased risk for developing nosocomial infections owing to their underlying disease process along with numerous invasive monitoring devices. METHODS: We retrospectively analyzed the rate, type, pathogens, outcomes, and risk factors of nosocomial infections that developed during adult patients on ECMO at our institution from 2012-2015. RESULTS: Compared to current ELSO reported adult nosocomial infections rate of 20.5%, we report our rate of 26% (CI 17.2%-34.7%). No significant differences were observed in mortality (42.3% vs. 36.5%; p=0.598), and presence of either antibiotics prior to ECMO (57.7% vs. 56.7%; p=0.934) or culture-proven infection prior to ECMO (19.2% vs. 32.4%; p=0.201). Patients who developed nosocomial infections had longer duration of ECMO (13 vs. 5 days; p<0.001), longer length of stay (36.5 vs. 18.5 days; p=0.004), and more days on ventilator (29 vs. 12.5; p=0.002). Duration of ECMO (OR=1.20, 95% CI 1.02-1.39; p=0.020) and duration of ECMO greater than 10 days (OR=14.65, 95% CI 1.81-118.78; p=0.012) were independent risk factors for developing nosocomial infections. However, there was no difference in mortality when duration of ECMO >10 days was compared with ≤10 days (28.5% vs. 43.1%; p=0.154). CONCLUSION: Nosocomial infections have no effect on survival in adult ECMO patients. Presence of either antibiotics or infection prior to ECMO has no effect on developing nosocomial infections while on ECMO. Duration of ECMO longer than 10 days is a major risk factor for developing nosocomial infection.
