A new measure, Conditional Length of Stay (CLOS), assesses hospital performance by identifying prolonged patient stays after day 3. This method helps evaluate care for complicated patients without needing complication data.

Area of Science:

  • Health Services Research
  • Biostatistics
  • Hospital Management

Background:

  • Assessing hospital performance is challenging when patient deaths are rare.
  • Existing outcome measures may not capture the nuances of care for patients with complications.
  • There is a need for objective measures to evaluate hospital management of complex cases.

Purpose of the Study:

  • To develop and validate a novel outcome measure, Conditional Length of Stay (CLOS).
  • To assess hospital performance in situations with rare deaths and unavailable complication data.
  • To provide a tool for policymakers to analyze the management of complicated patient care.

Main Methods:

  • Utilized engineering reliability theory and the Hollander-Proschan statistic.

  • Analyzed 1991-1992 MedisGroups National Comparative Data Base.
  • Examined 7,777 pediatric pneumonia and 3,413 pediatric appendectomy cases.

    • Main Results:

    • The Hollander-Proschan statistic indicated an "extended" pattern of Length of Stay (LOS) by day 3 (p<.0001) for both conditions.
    • This pattern correlated with declining discharge rates and increasing patient complication rates.
    • Worse admission severity and chronic disease were associated with lower discharge rates after day 3.

    Conclusions:

    • Patient stays tend to prolong following complications.
    • Conditional Length of Stay (CLOS) can identify the point at which hospital discharge rates diminish, signaling potential complications.
    • CLOS offers an objective outcome measure for analyzing hospital management of complicated patients without direct complication data.
