Equity, waiting times, and NHS reforms: retrospective study.

Area of Science:

• Healthcare policy research
• Health services research
• Socioeconomic determinants of health

Background:

• Waiting times for elective procedures are a key indicator of healthcare system performance and equity.
• Concerns existed that National Health Service (NHS) reforms might exacerbate socioeconomic disparities in access to care.

Purpose of the Study:

• To analyze changes in waiting times for elective hip replacement, knee replacement, and cataract repair in England from 1997 to 2007.
• To assess how these changes were distributed across different socioeconomic groups to evaluate equity.

Main Methods:

• Retrospective analysis of population-wide patient-level data from the English NHS (1997-2007).
• Ordinary least squares regression was used to examine the relationship between waiting times and socioeconomic status (Carstairs index of deprivation).
• Data included over 3.4 million patient records for hip replacement, knee replacement, and cataract repair.

Main Results:

• Mean and median waiting times initially increased before steadily declining by 2007.
• Overall variation in waiting times across the population decreased over the study period.
• The positive association between deprivation and waiting times diminished, with some deprived groups experiencing shorter waits than advantaged groups by 2007.

Conclusions:

• Waiting times for hip replacement, knee replacement, and cataract surgery in England decreased between 1997 and 2007.
• Socioeconomic inequity in waiting times for these procedures was reduced, contrary to some fears about NHS reforms.
• While direct causation is difficult to prove, NHS reforms did not negatively impact equity and may have contributed to improvements.
