Denis Campbell

Denis Campbell is Health Policy Editor at the Guardian and its Sunday sister title the Observer, specialising in health policy with a sustained focus on the National Health Service and the way system-level decisions shape care for patients. He has been writing about the NHS, public health and medicine at the Guardian since 2007, becoming Health Policy Editor in 2015 after a long period on the health beat. His coverage is defined by close attention to how demand, staffing and funding pressures affect the performance of services and access to treatment. Rather than concentrating on individual therapies, he tracks the resilience of the health system and the experiences of patients and staff within it across both the daily Guardian and the Observer.

NHS workforce, outsourcing and access

A recurring strand of Campbell’s work examines workforce shortages and their knock-on effects on NHS services. He has reported on the NHS paying private firms a record £216m in 2024 to examine X-rays and scans because hospitals have too few radiologists, setting out the financial and clinical implications of outsourcing core diagnostic work. In related coverage, he describes how failure to recruit radiologists into the NHS creates a “vicious cycle” in which doctors are drawn towards private work, deepening gaps in public provision. Another piece looks at overseas-trained dentists working in fast-food outlets despite millions of patients struggling to obtain NHS dental care, highlighting how bureaucratic obstacles prevent these clinicians from filling widespread gaps. Across these stories he shows how workforce planning and regulatory decisions directly determine whether patients receive timely diagnosis and treatment within the public system.

Patient safety, cancer and maternity care

Campbell devotes significant attention to patient safety, particularly in cancer care and maternity services. He has led front-page coverage on preventable cancers in the UK, drawing on a commissioned economic report to quantify how many people are expected to receive diagnoses that could have been avoided and the broader societal and economic costs of those cases.

That series interrogates the assumptions behind those projections and brings in expert commentary on their limitations and implications for prevention policy. In maternity care, his reporting includes analysis of a baby charities’ report that links delays in improving NHS services to hundreds of stillbirths and neonatal deaths each year, connecting findings to calls for more urgent reform.

These pieces combine stark data with institutional voices to show where systems are falling short and which changes are being demanded to protect patients.

Mental health, vulnerability and social harms

Mental health and wider social harms run through Campbell’s health coverage. He has written about research characterising the UK as becoming the “sick person of the wealthy world”, with rising deaths from drugs, suicide and violence contrasted with falling mortality from cancer, using those patterns to illustrate how social and policy factors drive health outcomes. Other reporting draws on professional bodies such as the Royal College of Psychiatrists and the British Medical Association to argue that the risks around mental health emergencies mean police should always attend, raising questions about how services share responsibility for people in crisis.

By combining epidemiological trends with perspectives from clinicians and campaigners, he links mental health, public safety and service design into a single picture of vulnerability.

Health misinformation and frontline impact

Alongside system-level reporting, Campbell covers the impact of misinformation on health services and patients. One recent piece details NHS staff confronting a surge of disinformation about food supplements, treating misleading health claims as a pressure on services in their own right as clinicians work to correct false beliefs.

Taken together with his broader focus on public health, this strand reinforces his interest in how information environments shape health behaviours and demand for care.

Across these beats, Campbell writes in a straightforward, report-led style that foregrounds data, institutional reports and expert testimony. His long tenure on the health beat gives him continuity to revisit themes such as NHS staffing, waiting times, funding decisions, mental health provision and inequalities in access over many years. For stories that interrogate how policy, resources and social conditions shape healthcare delivery within the NHS, he is a specialist with a consistent focus on systemic consequences for patients and staff.
