Description: As a result of the 1983 passage and implementation of the Tax Equity and Fiscal Responsibility ACT (TEFRA, PL 97-248) 10 years ago, nurses have studied nursing's economic contribution to the health care delivery system. Nursing intensity is an integral part of hospital nursing practice; therefore, one method of establishing and documenting the nursing contribution is to study the nursing intensity for each DRG and establish care strategies for each specific patient group.

This dissertation analyzed and described nursing intensity differences between DRGs 121 and 122, hospital length of stay, and hospital size. The sample data were obtained from the 1986 Medicus Corporation costing study. The sample included 702 patients, who were discharged with DRG 121 and 122 codes, and were from 19 hospitals in 6 HCFA regions that voluntarily reported data. Nursing intensity data were collected by the Medicus Corporation using the Medicus Type V patient classification tool. Statistical techniques included Analysis of Variance, Pearson's Correlation Coefficient, Spearman Rank Correlation, biserial correlation, and multiple regression. A conceptual model was tested, which posited that nursing intensity per DRG is a function of the patient's length of stay and hospital size.

Data demonstrated a significant (p $<$.000) difference in mean nursing intensity per DRGs. A weak positive relationship (p $<$.001) was demonstrated for DRG 121 nursing intensity and length of stay. Data for DRG 122 did not support an association (p $<$.476) of nursing intensity with length of stay. Data suggested significant nursing intensity mean differences per DRG, and hospital size. However, when the only hospital in the largest bed size group was eliminated, the findings were not significant. As proposed, data support that nursing intensity for DRG 121 is associated with a longer hospital stay and further study is needed to support that bed size has an effect on nursing intensity. Multiple regression test findings further supported that length of stay may be associated with nursing intensity for DRG 121 (p $<$.001) but probably not for DRG 122 (p $<$.476). The nurse administrator could utilize this data in the formulation of strategies for resource efficiency.
