Cancer patient experience, hospital performance and case mix: Evidence from England

Abstract

Aims: This study aims to explore differences between crude and case mix-adjusted estimates of hospital performance with respect to the experience of cancer patients. Materials & methods: This study analyzed the English 2011/2012 Cancer Patient Experience Survey covering all English National Health Service hospitals providing cancer treatment (n = 160). Logistic regression analysis was used to predict hospital performance for each of the 64 evaluative questions, adjusting for age, gender, ethnic group and cancer diagnosis. The degree of reclassification was explored across three categories (bottom 20%, middle 60% and top 20% of hospitals). Results: There was high concordance between crude and adjusted ranks of hospitals (median Kendalls τ = 0.84; interquartile range: 0.82-0.88). Across all questions, a median of 5.0% (eight) of hospitals (interquartile range: 3.8-6.4%; six to ten hospitals) moved out of the extreme performance categories after case mix adjustment. Conclusion: In this context, patient case mix has only a small impact on measured hospital performance for cancer patient experience. © 2014 Future Medicine Ltd.
