High-Risk Patients Face Increased Post-Surgery Death & Complication Rates – Study

The vast majority of deaths following surgery in the UK – nearly 80% – occur among patients already considered high-risk, according to a major new study published in The Lancet Public Health. The research, led by Queen Mary University of London and funded by the National Institute for Health and Care Research (NIHR), analyzed data from over 16 million surgical procedures carried out in England, Scotland, and Wales between 2015 and 2019. The findings underscore the urgent require for more tailored care and open conversations between clinicians and patients about surgical risks, particularly for those with pre-existing health conditions.

Around 300,000 surgical procedures each year are performed on individuals identified as high-risk. Within 90 days of surgery, these patients account not only for four out of five deaths, but as well for over half of all hospital bed days and nearly one-third of emergency readmissions. This highlights the significant strain placed on the National Health Service (NHS) by post-operative complications in this vulnerable group.

Beyond 30 Days: A More Complete Picture of Surgical Outcomes

For years, surgical success has often been measured by survival rates at 30 days post-operation. However, this study challenges that metric, demonstrating that it doesn’t fully capture the experience of high-risk patients. Researchers found that looking at longer-term survival, alongside factors like hospital stay length and overall quality of life, provides a more accurate assessment of surgical outcomes. This shift in perspective could lead to more effective strategies for improving care and potentially easing pressure on the NHS.

The study’s co-lead, Professor Rupert Pearse of Queen Mary University of London and Barts Health NHS Trust, explained that while surgery is safer than ever, high-risk patients are demonstrably more likely to experience adverse outcomes. “Although these patients make up fewer than one in ten surgical cases, their numbers are increasing as the population ages and more people live longer with chronic illness,” he noted. “It is therefore vital that we work to improve care for this group of patients, pre- and post-surgery, including having open conversations with patients about the individual risk of their procedure.”

The Role of Chronic Conditions and Frailty

Importantly, the research indicates that poor outcomes in high-risk patients aren’t typically due to technical errors during surgery or anesthesia. Instead, they are largely driven by post-operative complications related to pre-existing chronic health conditions, age, and frailty. This suggests that focusing on managing these underlying health issues before, during, and after surgery is crucial. Research on frailty has increasingly shown its impact on surgical recovery and overall health outcomes.

Perioperative Care: A Key to Reducing Risk

The study strongly advocates for greater investment in specialist perioperative services – comprehensive care that encompasses the period before, during, and after surgery. These services would be specifically tailored to the needs of older, high-risk patients. Dr. Tom Abbott, co-lead author and clinical senior lecturer at Queen Mary, emphasized that the decision to undergo surgery should be a carefully considered one, made by each individual after a thorough discussion with their surgeons and anesthesiologists about the potential benefits and risks. The Royal College of Anesthetists is already working to improve these specialist services.

The researchers analyzed health records from 13 million adults who underwent 16.1 million surgical procedures. This large sample size strengthens the validity of the findings, but it’s important to note that the data is retrospective, meaning it looks back at past events. Retrospective studies can identify associations, but they cannot definitively prove cause-and-effect relationships. The data is from 2015-2019, and healthcare practices may have evolved since then.

Understanding Risk: Absolute vs. Relative

While the study reports that high-risk patients account for 80% of post-surgery deaths, it’s crucial to understand what this means in terms of absolute risk. The overall risk of death following surgery remains relatively low for most people. However, for those with pre-existing conditions, the risk is significantly higher. This highlights the importance of individualized risk assessment and shared decision-making between patients and their healthcare providers. It’s also important to remember that these are population-level statistics; individual experiences will vary.

What’s Next: Refining Care and Improving Outcomes

The findings from this study are likely to prompt a review of current surgical pathways and a renewed focus on optimizing care for high-risk patients. Further research is needed to identify specific interventions that can effectively reduce post-operative complications and improve long-term outcomes. This includes exploring strategies for better pre-operative risk assessment, more personalized anesthesia plans, and enhanced post-operative monitoring and support. The National Institute for Health and Care Research (NIHR) will likely fund further trials to investigate these areas. Queen Mary University of London continues to lead research in this critical area.

the goal is to ensure that all patients, regardless of their risk profile, have access to the safest and most effective surgical care possible. Open communication, tailored treatment plans, and a commitment to ongoing research are essential to achieving this goal.
