Although some have recommended screening for femoral catheter\u2013associated thrombosis to prevent pulmonary embolism (PE), this strategy's economic implications are unclear. Therefore, we used a decision model to evaluate the potential cost-effectiveness of a Doppler ultrasound\u2013based screening strategy versus no ultrasound in averting thromboembolic complications associated with femoral catheters. The base-case analysis included a hypothetical cohort of 60-year-old medical patients treated for acute respiratory failure. The perspective was that of the health care payor, and the primary outcomes were quality-adjusted life expectancy, PE, and PE\u2013associated deaths. The ultrasound strategy cost $8,688\/quality-adjusted life-year (QALY) gained, $5,305\/PE averted, and $99,286\/PE death averted. The best- and worst-case scenarios, calculated in multiway sensitivity analyses by varying in-hospital mortality, deep venous thrombosis prevalence, and ultrasound accuracy, ranged from $1,170\/QALY to $35,342\/QALY, respectively. Probablistic analyses, in which variables with uncertain values were varied randomly within their ranges, demonstrated median costs of $12,793\/QALY (interquartile range $8,176\/QALY, $20,648\/QALY). In summary, ultrasound screening may improve outcomes among the critically ill with femoral venous catheters at acceptable costs and could complement venous thrombosis primary prevention programs.<\/jats:p>","DOI":"10.1164\/rccm.200303-367oc","type":"journal-article","created":{"date-parts":[[2003,8,4]],"date-time":"2003-08-04T20:30:14Z","timestamp":1060029014000},"page":"1481-1487","source":"Crossref","is-referenced-by-count":13,"title":["Cost-effectiveness
