Long NHS Wait Times Worsen Patient Health and Deepen Inequality, Reveals Study

Published: 25 July ‘2025. The English Chronicle Desk. The English Chronicle Online

A comprehensive study by the Health Foundation has uncovered troubling findings about the consequences of prolonged waits for NHS treatment. According to newly analysed patient-level data, individuals subjected to long waits are significantly more likely to require emergency care even after they finally receive treatment—highlighting a deeper and more systemic crisis within the UK’s healthcare infrastructure.

The research, shared with Sky News’ Data and Forensics Unit, shows a clear link between long delays and increased reliance on A&E services post-treatment. Patients who were treated within 18 weeks of being referred saw their weekly emergency department visits drop by 18% in the three months following their treatment. However, those who had waited over a year before receiving care experienced a 31% increase in A&E visits during the same period after treatment.

Experts interpret this as a sign that extended delays may reduce treatment efficacy and create additional complications, often necessitating further medical intervention. “The evidence points to not just a backlog of numbers, but a deterioration in patient health that continues long after the treatment has been administered,” said Dr Hilary Williams, incoming clinical vice president of the Royal College of Physicians. “Delays in care don’t just defer recovery—they often derail it.”

Inequalities in Waiting Times: A Stark Divide

The data also lays bare persistent inequalities in who waits the longest for NHS care. Women, people of Asian descent, and individuals from more deprived areas are statistically more likely to face longer delays than men, white patients, and those from wealthier communities. While the differences may seem marginal—less than two percentage points—they are statistically significant and represent a troubling pattern of health inequality.

Strikingly, these disparities remain even when adjusted for age, frailty, and socio-economic status. This suggests a deeper, systemic bias in how healthcare access is prioritised and managed. “Sunlight is the best disinfectant,” said Health and Social Care Secretary Wes Streeting, acknowledging the issue. “Only by being upfront and shining a light on inequalities can we begin to tackle the problem.”

The Hidden Cost of Waiting

The Health Foundation’s findings are not just anecdotal—they are backed by hard figures. Since 2010, the NHS has paid out over £8.3 billion in compensation related to injury and death due to delayed care. Additionally, increased A&E visits, a rise in GP appointments, and the heavier use of pain relief medication all contribute to the mounting costs of inaction.

For some patients, the delays prove fatal. Approximately one in every 200 people on the NHS waiting list—equivalent to roughly 30,000 individuals—die before receiving the care they need. Others exit the list due to a “decision not to treat,” which can include a shift to private care or a clinical decision to manage symptoms in primary care without further treatment. A smaller share of patients are removed due to missed appointments, a problem more prevalent among the most deprived populations.

Some Specialties Face Far Longer Waits Than Others

The research reveals pronounced disparities depending on the nature of the medical issue. Oral surgeries involving the mouth and jaw have the longest wait times, with more than half of all patients waiting beyond the 18-week threshold. In contrast, services catering to older adults, as well as certain cardiac and ophthalmology cases, tend to receive quicker attention.

The variation is partly attributed to prioritisation policies post-pandemic, where conditions deemed less life-threatening—such as gynaecological or ENT issues—were often deprioritised. Treatments requiring overnight hospital stays or involving specialist expertise also tend to experience longer delays due to resource constraints and staffing shortages.

A Call for Transparency and Targeted Support

Charles Tallack, Director of Research and Analysis at the Health Foundation, emphasised the need for better data utilisation. “While reducing the elective care waiting list is rightly a government priority, we must understand the human impact behind these numbers,” he said. “We need better, more transparent data to identify who’s being left behind and why.”

He also called on the NHS to provide enhanced support for patients most at risk during long waits, particularly those with complex conditions or limited means. “This isn’t just about clearing a list—it’s about recognising suffering, reducing harm, and ensuring equitable access to care,” Tallack added.

Political Promises Amid Public Pressure

The government’s current pledge is to reduce the number of patients waiting over 18 weeks for treatment to below 8% by the end of the parliamentary term. Yet, nearly five times that number currently exceed the target timeframe, and the problem is even worse in certain parts of the country.

Similarly, A&E performance remains far off the mark. While the government’s goal is that 95% of patients should be seen within four hours of arrival, current figures show one in four patients waiting longer.

The Path Forward

The NHS stands at a critical juncture. While the backlog may have been exacerbated by the pandemic, its roots run deeper—into decades of policy decisions, underfunding, and increasing demand.

As Dr Williams aptly summarised: “This is not just a question of efficiency. Long waits take lives, exacerbate inequality, and increase suffering. Addressing them is a moral, medical and political imperative.”

The new data sheds powerful light on the systemic challenges facing the NHS—and raises urgent questions about how the UK will move forward to rebuild a system that truly delivers timely and equal care for all.
