Hospital mortality rates in England vary significantly. Emergency admission rates are the strongest predictor of these variations, with higher doctor-to-population ratios linked to lower death rates.

Area of Science:

  • Healthcare outcomes research
  • Public health policy
  • Hospital administration

Background:

  • Significant variations exist in hospital inpatient mortality ratios across England.
  • Understanding the drivers of these variations is crucial for improving patient care and resource allocation.

Purpose of the Study:

  • To quantify hospital inpatient mortality in England.
  • To identify key factors influencing variations in standardized hospital death ratios.

Main Methods:

  • Weighted linear regression analysis of routinely collected data over four years.
  • Utilized eight million hospital discharge records from NHS hospitals.
  • Focused on diagnoses accounting for 80% of inpatient deaths.

Main Results:

  • Standardized hospital mortality ratios ranged from 53 to 137 (average 100), with crude death rates from 3.4% to 13.6%.
  • The percentage of emergency admissions was the primary predictor of mortality variation.
  • Ratios of hospital doctors to beds and general practitioners to population were also significant predictors.

Conclusions:

  • Wide variations in standardized hospital mortality ratios are evident in England.
  • The proportion of emergency admissions is the most influential factor in mortality variation.
  • Higher ratios of healthcare professionals to population served are associated with lower hospital death rates.
