RESUMO
The etiology of anemia in adults is often multifactorial. This case highlights an uncommon combination of causes of anemia and the importance of a diagnostic workup guided by a patient's unique history, risk factors, and laboratory findings.
RESUMO
BACKGROUND: Malnutrition has been linked to poor outcomes after elective joint arthroplasty, but the risk of unplanned postoperative intensive care unit (ICU) admission in malnourished arthroplasty patients is unknown. METHODS: 1098 patients were followed as part of a prospective risk stratification program at a tertiary, high-volume arthroplasty center. Chronic malnutrition was defined as preoperative albumin <3.5 g/dL. RESULTS: The overall incidence of malnutrition was 16.9% (primary and revision arthroplasty patients). Average BMI was highest for patients in albumin category 3.0-3.5 (BMI 35.7). Preoperative albumin <3.0 and <3.5 g/dL translated to 15.4% and 3.8% rates of unplanned ICU admission, respectively, indicating nutritional status to be a factor in postoperative ICU admission. CONCLUSION: Patients with poor nutritional status must be counseled on the risks of adverse medical complications.
RESUMO
The morbidity associated with elective total hip arthroplasty (THA) may result in intensive care unit (ICU) admission. A total of 175 consecutive THA patients were prospectively triaged to either an ICU bed or routine post-operative floor according to admission criteria based on a prior published study of 1259 THA patients. Primary end points were a reduction in unplanned ICU admission, as well as major complications. With our triage model, the rate of unplanned ICU admissions dropped from 7.1% to 2.2% (P=0.013). The as-treated odds of unplanned admission pre- versus post-intervention were 3.2 (1.2, 10.6). The complication rate fell from 12.5% to 2%, and the mortality index decreased from 4.77 to 1.62. Triage according to selected risk factors affects a reduction in unplanned ICU admissions and major complications after THA.

Triage to the intensive care unit (ICU) after elective total hip arthroplasty proves a complex medical and resource decision point. A total of 1259 consecutive total hip arthroplasties were reviewed; 89 patients experienced unplanned ICU admissions. Significant risk factors for ICU admission in univariate analysis were age greater than 75 years, revision surgery, obstructive sleep apnea, creatinine clearance less than 60 mL/min, prior myocardial infarction, American Society of Anesthesiologist class 3 or greater, use of vasopressors intraoperatively, and body mass index greater than 35 kg/m(2). With multiple regression, age greater than 75 years (odds ratio [OR], 2.6 [1.2-5.6]), revision surgery (OR, 5.8 [3.0-11.4]), creatinine clearance less than 60 mL/min (OR, 6.5 [2.5-16.3]), prior myocardial infarction (OR, 7.2 [2.0-25.4]), and body mass index greater than 35 kg/m(2) (OR, 2.9 [1.4-6.2]) were predictive of unplanned ICU admission. With 1 risk factor, the risk of ICU admission was 40%, 2 (75%), 3 (93.5%), 4 (98.5%), and 5 (>99%). A prospective study of these risk factors is needed to establish a threshold for planned ICU admission.
