July effect in hospitalized cirrhosis patients: A US nationwide study using difference-in-differences analysis

Area of Science:

• Hepatology
• Healthcare Management
• Clinical Outcomes Research

Background:

• The "July effect" in US teaching hospitals is debated, with prior studies yielding conflicting results.
• Physician turnover, particularly in July, may impact patient care quality.
• Evaluating this effect in patients with cirrhosis is crucial due to their complex needs.

Purpose of the Study:

• To assess the impact of physician turnover in July on clinical outcomes for hospitalized cirrhosis patients.
• To compare mortality and length of stay (LOS) between teaching and non-teaching hospitals during July.

Main Methods:

• Utilized the Nationwide Inpatient Sample database (2016-2019).
• Identified patients with cirrhosis and liver-related complications (variceal bleeding, hepatorenal syndrome, acute-on-chronic liver failure).
• Employed difference-in-differences analysis comparing May and July outcomes, and analyzed trends in other months.

Main Results:

• No significant difference in mortality was observed between teaching and non-teaching hospitals for cirrhotic patients.
• Teaching hospitals showed a greater increase in length of stay (LOS) in July compared to May, relative to non-teaching hospitals.
• Increased LOS in teaching hospitals persisted in months following July, gradually diminishing over time.

Conclusions:

• July physician turnover did not elevate mortality rates for cirrhosis patients.
• However, it was associated with prolonged hospital stays (LOS) in teaching hospitals.
• Highlights the need for enhanced supervision and operational strategies to manage trainee transitions and mitigate disruptions in patient care.
