Area of Science:

  • Healthcare Quality Improvement
  • Health Services Research
  • Medical Informatics

Background:

  • Hospital administrative data is crucial for quality assessment.
  • Identifying patient complications and deviations from normative care practices is essential for improving healthcare quality.
  • Traditional methods for identifying these issues using administrative data have limitations.

Purpose of the Study:

  • To investigate the utility of unexpected length of stay (LOS) as an indicator for identifying hospital patients with complications.
  • To determine if unexpected LOS can identify patients whose care exhibited low adherence to normative practices.
  • To compare the effectiveness of unexpected LOS with traditional administrative data methods for quality assessment.

Main Methods:

  • Analysis of 1,477 cases across three medical conditions from nine Department of Veterans Affairs (VA) hospitals.
  • Development of multiple linear regression models using LOS as the dependent variable.
  • Utilizing administrative data and chart reviews, including severity of illness, complications, and process of care criteria.
  • Defining unexpectedly long LOS for complications and unexpectedly short LOS for low adherence.

    • Main Results:

    • Unexpectedly long LOS identified complications with 40-62% sensitivity, outperforming ICD-9-CM codes (26-39% sensitivity).
    • Unexpectedly short LOS identified low provider adherence with 33-45% sensitivity.
    • Positive predictive values for both indicators were statistically significant (p < .05).
    • Incorporating chart-based severity of illness data did not significantly improve the identification of complications or low adherence beyond administrative data alone.

    Conclusions:

    • Unexpected length of stay (LOS) derived from administrative data serves as a valuable indirect measure for identifying potential patient complications and low adherence to care practices.
    • This approach offers a more sensitive method for quality monitoring compared to traditional administrative coding systems.
    • Further validation of unexpected LOS is recommended as a hospital-level quality indicator to enhance the utility of administrative data for quality improvement initiatives.
