IQCE Policy Brief No. 2, November 2019: "The casual effect of hospital volume on health gains from hip replacement surgery" by Laurie Rachet Jacquet
Key Findings
• Hospital volume does not have a causal impact on hip-specific patient-reported health outcomes for planned primary hip replacements in the English NHS.
• The clinically small and positive volume-outcome correlation disappears once we adjust for the confounding effect of hospitals’ quality reputation on volume (volume endogeneity).
