Abstract Background Private healthcare is a rapidly growing industry in the UK, particularly for surgical procedures. Across the pandemic period, waiting lists for elective surgical and consultant-led care increased from 4.4 to 7.5 million patients. This study aimed to analyse the trends and geographical variations in privately funded and NHS-funded orthopaedic private procedures across England compared to NHS waiting times. Methods We conducted a longitudinal study using quarterly national data between 2019 and 2023 in England. Descriptive analysis of quarterly orthopaedic surgical volumes per 10,000 people, and quarterly orthopaedic surgery wait times stratified by geographical location and time period was conducted. Results Between 2019 and 2023 there were a total of 1,469,450 procedures across the private sector, comprising 1,030,095 NHS-commissioned private orthopaedic procedures and 439,355 private orthopaedic procedures. The South of England performed a higher total number of private procedures per year compared to the North (63 vs 57/10,000 people); whilst there was almost double the number of privately funded procedures (23 vs 12/10,000), the difference was less amongst NHS-funded procedures (45 vs 40/10,000 respectively). There was a large variation in the number of NHS-funded procedures per 10,000 between regions. The North has consistently shorter waiting times than the South. Conclusions Our findings indicate considerable geographical variation in the use of private healthcare between regions, suggesting a two-tier healthcare system. The founding principles of the NHS, healthcare free at the point of use based on clinical need irrespective of ability to pay, continue to be eroded. Policy makers and politicians urgently need to find solutions to ensure all members of society can access the same high quality health care. Key messages • Private healthcare utilization in the UK for orthopaedic procedures, has increased significantly, contributing to an emerging two-tier healthcare system. • There are large geographical disparities in access to healthcare services, with he South of England performing more private proceeds with longer NHS waiting times compared to the North.
