The simple act of managing insulin, a lifeline for millions living with diabetes, can become a dangerous gamble when patients enter the hospital. A modern investigation by the Health Services Safety Investigations Body (HSSIB) reveals a pattern of “blind spots” in hospital care, where patients dependent on insulin are experiencing avoidable harm – and in some cases, death – due to inconsistent or inadequate diabetes management. The findings underscore a critical gap in patient safety, even as hospitals strive to provide comprehensive care.
The report, published March 26, 2026, details how patients who safely self-administer insulin at home often lose that autonomy and consistent support during hospital stays. This disruption, even if brief, can have devastating consequences. The investigation highlights a lack of consistent protocols, variable staff training, and a failure to fully integrate blood glucose monitoring into standard patient deterioration assessments. The core issue isn’t a lack of dedication from hospital teams, but systemic failures that set vulnerable patients at risk.
The HSSIB investigation was prompted by a growing number of reported incidents and concerns raised by patients and their families. Craig Hadley, a senior safety investigator with the HSSIB, stated, “Our investigation shows that, despite the dedication of hospital teams, patients with diabetes who rely on insulin still face persistent and avoidable risks when they come into hospital. When insulin management is disrupted—even briefly—the consequences can be serious as we heard from patients and families who shared their distressing experiences of harm, to themselves or their loved ones.”
Deadly Errors in Insulin Management
The report cites several specific examples of harm directly linked to inadequate insulin management. In one tragic case, an insulin infusion was stopped before surgery and was never restarted, contributing to a patient’s death. Another involved a patient who consistently received insulin after meals, rather than before as prescribed, a practice that ultimately proved fatal. Further incidents included the administration of an incorrect, and fatally high, insulin dose. These aren’t isolated occurrences; the HSSIB found evidence of similar errors happening repeatedly, even in later incidents with other patients.
These errors aren’t necessarily the result of malicious intent, but rather a combination of factors. The HSSIB found significant variation in the confidence and training levels of non-specialist staff tasked with managing diabetes care. While inpatient diabetes teams exist, their reach isn’t consistent across all hospitals or all patients. This reliance on staff who may not have specialized knowledge creates opportunities for critical mistakes.
Systemic Issues and Oversight Gaps
Beyond individual errors, the investigation uncovered broader systemic problems. The HSSIB identified inconsistent reporting and oversight of inpatient diabetes safety at the local, system, and national levels. This lack of standardized monitoring makes it tough to track incidents, identify trends, and implement effective solutions.
A particularly concerning finding is the exclusion of blood glucose readings from the National Early Warning Score 2 (NEWS2), a widely used system for identifying patients at risk of deterioration. NEWS2 is designed to flag patients whose vital signs indicate a potential medical emergency, but its current iteration doesn’t account for the critical role of blood glucose levels in diabetic patients. This omission means that dangerously high or low blood sugar levels may go unnoticed until a patient is already in a critical state.
The Role of Patient Self-Management
The HSSIB report emphasizes the importance of supporting patients to self-administer insulin whenever possible, mirroring the practices they successfully employ at home. Many individuals with diabetes are highly skilled in managing their condition and are best equipped to monitor their own blood glucose levels and adjust their insulin dosages accordingly. However, hospital protocols often discourage or outright prevent this self-management, leading to a loss of control and increased risk of errors.
Allowing patients to participate in their own care, where appropriate, not only empowers them but also reduces the burden on already stretched hospital staff. The report suggests that hospitals should prioritize developing clear guidelines and training programs to facilitate safe and effective patient self-management of insulin.
Recommendations for Improved Patient Safety
The HSSIB report makes several key recommendations aimed at improving inpatient diabetes care. These include strengthening regulatory activity to ensure hospitals are adhering to best practices, improving national oversight and assurance mechanisms to track and address safety concerns, and examining how to integrate blood glucose monitoring into existing patient deterioration assessment systems like NEWS2.
The organization also calls for a greater focus on staff training and education, ensuring that all healthcare professionals involved in the care of diabetic patients have the knowledge and skills necessary to provide safe and effective insulin management. The HSSIB stresses the need for better communication and collaboration between hospital teams, patients, and their families.
The findings from this investigation are a stark reminder that even in the most advanced healthcare settings, patient safety can be compromised by systemic failures. Addressing these “blind spots” in insulin management is crucial to preventing future harm and ensuring that individuals with diabetes receive the care they deserve.
The HSSIB will continue to monitor the implementation of its recommendations and will publish further updates on progress in the coming months. The next scheduled update is expected in September 2026, when the HSSIB will present its findings to the National Institute for Health and Care Excellence (NICE) for review.
