High-risk medications are treatments with an increased risk of causing errors or incidents that could seriously harm patients' health and safety. These risks can arise from their composition, method of administration, or management during care.

Identifying these medications is essential to reducing adverse events, often preventable, that affect the quality and safety of care. Tools and initiatives, such as those developed by the regional OMEDITs (Brittany, PACA-Corsica, Centre-Val de Loire), help healthcare professionals ensure rigorous management. The goal: to administer the right medication, at the right dose, at the right time, and to the right patient.

Discover in this article the challenges related to these medications and the strategies to strengthen patient safety. You will also learn how everyone, professional or patient, can contribute to preventing errors.

Understanding High-Risk Medications

Definition and Categorization

A high-risk medication is a product whose use requires a enhanced security at every stage: prescription, dispensing, taking, administration, and therapeutic monitoring. This vigilance is essential to avoid errors that could have serious, even fatal, consequences for patients.

In France, this concept is governed by a decree dating from April 2011, which highlights that these medications often have a narrow therapeutic index. Internationally, they are called "High-Alert Medications" by organizations such as the Institute for Safe Medication Practices (ISMP). This institute regularly publishes a globally recognized list.

The most common categories include anticoagulants, insulins, narcotics and sedatives, and concentrated electrolyte solutions.

Criteria that make a drug a potential risk

Several criteria determine whether a drug presents a high risk. First, a narrow therapeutic index means that the difference between an effective dose and a toxic dose is small, requiring precise control. Furthermore, the complexity of the administration or management, such as rapid intravenous injection or the use of medications in psychiatry, can increase the risk of incidents. Errors can also arise from confusion between medications with similar names or appearances. Finally, some treatments require constant monitoring after administration, and the consequences of an error can be particularly serious, justifying their classification in this category.

Factors Contributing to Medication Errors

Many factors explain medication errors, particularly for high-risk medications. First, failure to follow official recommendations, such as those in the Summary of Product Characteristics (SmPC) or guidelines for healthcare professionals, is a frequent cause. This includes errors in dosage, duration of use, or failure to follow specific precautions.

Approximately 16% of adverse drug events could be avoided through better adherence to protocols. Furthermore, administration errors due to complex procedures, incorrect patient identification, or communication problems between healthcare teams significantly increase the risks. Finally, inappropriate self-medication or misuse by the patient also plays a role. This underlines the importance of clear information and appropriate training at all levels to ensure optimal safety.

Risk Prevention and Management Strategies

Improving Prescribing Practices

To Limit Risks Regarding high-risk medications, it is important to work on improving prescribing practices. This includes continuing education for healthcare professionals to raise their awareness of the specific characteristics of these medications and high-risk medication situations. The implementation of clear and validated protocols, as well as the use of computer-aided prescribing tools, plays a crucial role in reducing dosage or therapeutic choice errors. Furthermore, the customization of the list of high-risk medications by each healthcare facility, in accordance with the recommendations of OMEDIT or international organizations, allows for better targeting of risks specific to each local context. Securing the medication circuit is a central pillar in preventing administration errors. This requires strict organization of the medication's journey, from dispensing at the pharmacy and storage under appropriate conditions to administration to the patient, with systematic double-checking. Measures such as the use of specific lists of high-risk medications, clear distinction of vials, and the implementation of local initiatives to limit visual similarities help to reduce confusion. Furthermore, tools such as barcode systems and electronic traceability enhance the safety of care in healthcare facilities.

Role of Healthcare Professionals and Pharmacovigilance

Healthcare professionals play a vital role in preventing medication errors associated with high-risk drugs. Their vigilance, specific training, and ability to collaborate in a multidisciplinary manner are essential for quickly identifying and correcting anomalies.

Furthermore, pharmacovigilance is a key element of risk management. It relies on the active monitoring of adverse events and feedback, allowing for adjustments to practices and lists of high-risk drugs.

Regional organizations like OMEDIT play a valuable role by disseminating safety alerts and supporting facilities in their quality improvement initiatives.

Technology and innovation at the service of safety

Digital Monitoring and Alerting Tools

Technological advances have profoundly transformed the risk management associated with high-risk medications. Dedicated digital tools now allow for precise monitoring and rapid alerts in critical situations.

A notable example is the MEDISSIMO platform, which offers a detailed medication review. This solution centralizes all information related to patient treatments, whether they are in a healthcare facility or at home.

It guarantees complete traceability, from dispensing at the pharmacy to actual administration by the patient. This process involves all stakeholders: pharmacist, nurse, patient, and even their family. These digital tools strengthen collaboration between healthcare professionals and ensure rigorous monitoring, thus reducing the risks of administration errors and undesirable drug interactions.

Artificial intelligence to detect risks

Artificial intelligence (AI) is now a key lever for strengthening patient safety with regard to high-risk medications. By analyzing massive volumes of pharmacovigilance data, AI can detect early warning signs of adverse events or medication errors in real time. Combined with Big Data, AI automates reporting and anticipates risks using powerful algorithms capable of identifying complex patterns. This technology is revolutionizing drug monitoring, offering increased responsiveness and unprecedented transparency. It plays an important role in protecting the safety of care, particularly within the framework of systems supported by OMEDIT, at the national and regional levels. Specific cases of high-risk medications: High-alert medications. High-risk medications, also known as "high-alert medications," refer to a specific category of treatments that require heightened vigilance. Their distinguishing characteristic is their high potential to cause serious adverse events in the event of an error. These medications often have a narrow therapeutic index, meaning that even a slight overdose or incorrect administration can lead to severe toxic effects. Among the medications concerned are anticoagulants, chemotherapeutic agents such as 5-fluorouracil (5-FU), insulins, products used in anesthesia and intensive care, as well as certain psychiatric treatments. These substances, by their very nature, require special attention to avoid any errors that could endanger patients' health. To ensure their safe use, strict protocols govern their prescription, dispensing, storage, and administration in healthcare facilities. These protocols are often reinforced by regional initiatives led by organizations such as the OMEDIT (Observatories of Medicines, Medical Devices and Therapeutic Innovation) in regions like Brittany, Provence-Alpes-Côte d'Azur-Corsica, and Centre-Val de Loire. These approaches aim to reduce frequent errors, such as injection errors, dosage or molecule mix-ups, while ensuring optimal therapeutic monitoring. Finally, some medications, such as fenfluramine and Mediator, have been withdrawn from the market or subjected to restrictions due to their proven major risks. These examples illustrate the importance of continuous monitoring and heightened vigilance for high-risk medications to best protect patients.

Policies and Regulations

International Standards and Local Guidelines

Regulation of Medicines Risk management relies on international standards designed to harmonize the safety and quality of medical products globally. Organizations such as the International Council for Harmonisation (ICH) and the ICMRA coalition, which brings together regulatory authorities from many countries, play a key role in developing common guidelines. These guidelines promote consistent risk management for medicines and encourage cooperation among national bodies. This allows for faster access to safe and effective treatments, while ensuring rigorous monitoring of adverse events and transparent communication between the various stakeholders in the sector. In France, the decree of April 6, 2011, specifically regulates medication management in healthcare facilities. This decree emphasizes the safety of prescribing, dispensing, storing, and administering medications with a narrow therapeutic index. These provisions are aligned with international best practices, thus ensuring optimal management of the most sensitive medicines.
