title: Comparison of one-day and three-day calorie counts in hospitalized patients: a pilot study.
abstract: OBJECTIVE
  To determine whether a 1-day calorie count can replace the labor-intensive 3-day calorie count commonly, performed in hospitalized patients when estimates of caloric and protein intake are required.
  
  
  METHODS
  Pilot study using prospective, non-concurrent review of medical records.
  
  
  METHODS
  Hospital.
  
  
  METHODS
  Thirty patients (mean age 67 years).
  
  
  RESULTS
  Mean 3-day intake (952 +/- 91 calories, 41 +/- 4 g protein) was about half of calculated requirements; first-day intake was similar (918 +/- 116 calories, 40 +/- 5 g protein). The first day had high sensitivity (calories 96%; protein 93%) and positive predictive value (calories 100%; protein 96%). Malnutrition was evident; three-fourths of patients had weights below recommended ranges, and 83% were hypoalbuminemic.
  
  
  CONCLUSIONS
  Three-day calorie counts are frequently performed in patients suspected of eating poorly. Results of this pilot study suggest that 1-day calorie counts may be a valid alternative. However, readily available anthropometric and biochemical data may be as good an indicator of inadequate dietary intake.
