Precision in diagnosis – Safeguarding patient health

An Incident Is Just A Tip Of The Iceberg, A Sign Of A Much Larger Problem Below The Iceberg – Don Brown

In healthcare, precision in diagnosis can mean the difference between life and death. The World Health Organisation (WHO) underscores this in its 2024 World Patient Safety Day theme: “Improving Diagnosis for Patient Safety,” urging healthcare professionals to “Get it right, make it safe.” Accurate diagnosis is the foundation of patient care, yet diagnostic errors continue to be a major threat to patient safety globally.

Diagnostic errors — whether delayed, missed, or incorrect — pose significant risks to health outcomes. According to WHO, these errors are often caused by a combination of systemic failures and cognitive factors that go unnoticed until they cause harm. Medical errors, particularly in diagnosis, have now emerged as a public health crisis, ranked as the third leading cause of death in the U.S. alone. It’s estimated that preventable harm affects about 400,000 hospitalised patients every year, and diagnostic errors lead to over 200,000 deaths annually. Beyond the human cost, the financial burden is staggering, with adverse events costing healthcare systems up to $45 billion annually.

Given these high stakes, healthcare providers and leaders must focus on improving diagnostics to ensure patient safety. By analysing current challenges and implementing actionable strategies, healthcare systems can better support professionals and reduce errors.

The weight of diagnostic errors

Diagnosis is a complex process. While patients often view their doctors as infallible, healthcare professionals know that the responsibility of getting the diagnosis right is enormous. Diagnostic errors are frequently the result of systemic issues like communication breakdowns, overwhelming workloads, and lack of teamwork. On a personal level, factors such as fatigue, stress, and cognitive biases can cloud a clinician’s judgment.

The impact of these errors is far-reaching. Patients suffer physically and emotionally, while healthcare professionals may endure guilt, depression, and even suicidal thoughts. The ripple effects of medical errors extend beyond individual patients, affecting families, communities, and entire healthcare systems.

Actionable advice

Fostering transparency

To improve diagnostic accuracy, healthcare systems must create a culture of transparency. Clinicians need to feel safe admitting mistakes without fear of punishment. Encouraging open discussions about errors and near-misses helps professionals learn from each other’s experiences, reducing the risk of future errors. This approach also helps relieve the emotional burden on healthcare workers. Institutions should provide mental health resources and peer support programmes to help clinicians manage stress and avoid burnout.

Systemic issues burdening healthcare providers

Systemic challenges like understaffing, inadequate training, and high patient volumes increase the likelihood of diagnostic errors. Clinicians often have little time to reflect on complex cases, which widens the margin for error. However, diagnostic errors are not solely the fault of individual providers. Often, the healthcare system itself — characterized by fragmented communication, outdated technology, and inefficient workflows — also plays a role.

Actionable advice 

Enhancing interdisciplinary collaboration

Healthcare leaders can address systemic issues by fostering better interdisciplinary collaboration. Improving communication between healthcare workers is essential for reducing diagnostic errors. Team-based care models allow physicians, nurses, and other professionals to work together more effectively, ensuring no aspect of patient care falls through the cracks. Investing in better technology, such as improved electronic health records (EHRs), is also critical for sharing accurate and timely patient information.

Cognitive bias in diagnosis

Cognitive biases can significantly affect diagnosis. Clinicians, like their patients, are human and susceptible to mental shortcuts, especially under pressure. Anchoring bias, where a clinician becomes fixated on an initial diagnosis, and confirmation bias, where only information that supports that diagnosis is considered, are common issues that can lead to errors.

Actionable advice 

Cognitive bias training

Healthcare institutions must offer training to help clinicians recognise and avoid cognitive biases. By teaching providers to be aware of these mental traps, diagnostic accuracy can be improved. Cognitive bias training should be an ongoing part of professional development, ensuring that clinicians remain alert to how their thought processes can impact patient care.

The emotional toll of medical errors

Medical professionals are trained to save lives, and when errors occur, the emotional toll can be overwhelming. Guilt, self-doubt, and burnout are common reactions, and these emotions can impair a provider’s ability to perform effectively. The fear of litigation or punishment often makes clinicians reluctant to admit mistakes, even when doing so could prevent future errors.

Actionable advice

Supporting clinician mental health

Healthcare systems must prioritise mental health support for providers. Establishing peer support groups, offering counselling, and creating an environment where discussions about mental health are normalised can help clinicians cope with the emotional challenges of their jobs. When providers feel supported, both their wellbeing and patient outcomes improve.

A path forward for patient safety

As the healthcare field continues to evolve, addressing diagnostic errors will be crucial for improving patient safety. By fostering a culture of transparency, promoting interdisciplinary collaboration, training clinicians on cognitive biases, and supporting their mental health, healthcare systems can reduce diagnostic errors and save lives.

Patient safety depends on the collective efforts of healthcare professionals, leaders, and policymakers. By “getting it right” and making it safe, we can ensure a healthier future for all.
