Pounds of cure: chart weight as a measure of service intensity.
Intensity of hospital services is often estimated by length of stay (LOS). Increasing demands for documentation in the medical record suggested to us an alternate method: weighing the chart. In a retrospective study, we compared LOS and chart weight as predictors of actual hospital costs at a community teaching hospital. We reviewed a sample of 123 patients randomly chosen from the medical service and stratified by phase of the academic year. Both least-squares regression and a multiple sampling/validating technique were used to derive mean cost per ounce of chart and per day of stay. Costs estimated from weight were within 7% and from LOS within 14% of measured actual costs among patients not used to derive the formulae. We conclude that the intensity of paper documentation closely reflects actual costs; the same may be true of bytes or key-strokes for electronic records.
