- Avoid Verbal Orders: Avoid giving or accepting verbal medication orders or prescriptions.
- Pharmacy Stocking: Pharmacies should avoid stocking medication with packaging prone to similar-looking errors.
The Seven Myths of Human Error
- Errors are Intrinsically Bad: Errors are not inherently bad.
- Bad Errors are Made by Bad People: This is untrue, errors are often system-related.
- Errors are Random and Highly Variable: There are usually underlying causes.
- Practice Makes Perfect: People may get better over time but errors can still occur.
- Errors of Highly Trained Professionals are Very Rare: High-level professionals can make mistakes too.
- Errors of Highly Trained Professionals are Usually Sufficient to Cause Bad Outcomes: It is not the error itself but the system design that can lead to bad outcomes.
- It is Easier to Change People than Situations: Changing system design and processes is often more effective than trying to change people.
Reason's Model of Accident Causation
- Latent Conditions: These are usually long-term problems within an organization, like poor communication or inadequate training, which can contribute to errors.
- Error Producing Conditions: These are environmental, team, individual or task factors that affect performance and can contribute to errors.
- Active Failures: These are the actual errors that happen (e.g. a slip, a mistake, a violation).
Error Reduction Strategies
- Prescribing Safety Assessment (PSA): A tool for assessing prescribing skills and minimizing errors. It covers 8 sections and 60 items, designed for a total 120 minutes.
- Patient Empowerment: It is important to empower patients to be active participants in their own medication safety.
Key Takeaways
- To err is human, to cover up is unforgivable but to fail to learn is inexcusable.
- Medication errors are preventable and improving systems and processes is crucial.
- Medication errors can have serious consequences, but by sharing learning and focusing on prevention, we can improve patient safety.
The Medication-Use Process
- The process includes prescribing, transcribing, dispensing, administering, and monitoring medications.
- All healthcare professionals are involved in this process, including doctors, pharmacists, nurses, and dieticians.
The Prescribing Competency Framework
- Provides guidelines and standards for safe and effective prescribing.
The Cambridgeshire Enquiry
- An important case study that highlights the risks of medication errors.
- A patient was prescribed methotrexate for rheumatoid arthritis.
- The GP inadvertently prescribed a higher dose than intended, leading to a near-fatal overdose.
- This case highlights the importance of clear communication, legible handwriting, and careful medication review.
Prescribing Errors
- Are common and can have serious consequences.
- Examples of prescribing errors include incorrect dosing, drug interactions, illegible handwriting, and electronic prescribing errors.
Risk Management: The Right Medicine
- Take a full drug history of the patient, including all medications, allergies, and concerns about medications.
- Choose the most appropriate medication using resources like the BNF (British National Formulary) and guidelines.
Risk Management: Legibility
- Use clear and legible handwriting when prescribing, avoiding abbreviations.
- Write out the full name of the medicine, and specify the dose and unit clearly.
- Use a clear and consistent format for writing numbers, avoiding trailing zeros and using the preceding zero when necessary.
Risk Management: Abbreviations
- Avoid using abbreviations as they can lead to misinterpretations and errors.
- Refer to the Joint Commission's “Do Not Use” list for a list of abbreviations that should be avoided.
Dispensing and Administration Errors
- Can also lead to serious consequences.
- One common type of error is a sound-alike, look-alike drug (SALAD) error.
SALAD Errors
- Occur when medications with similar-sounding or similar-looking names are confused.
- Examples of SALAD pairs include Aminophylline/Amitriptyline, Amantadine/Amiodarone, and Naloxone/Lanoxin.
Strategies to Reduce SALAD Errors
- Write the full drug name when prescribing, never abbreviate.
- Include the indication for the medication to increase clarity.
- Specify the exact dose on the prescription.
- Consider “tall man” lettering for high-alert SALAD pair names to highlight key differences.
- Avoid verbal medication orders.
The Seven Myths of Human Error
- Errors are not intrinsically bad.
- Errors are not always made by bad people.
- Errors are not always random.
- Practice does not always make perfect.
- Highly trained professionals can also make mistakes.
- Errors by highly trained professionals do not always lead to bad outcomes.
- It is often easier to change systems than people.
Reason’s Model of Accident Causation
- Explains how accidents, including medication errors, can occur due to a combination of latent conditions and active failures.
- Latent conditions are organizational factors, processes, and management decisions that create a risk for errors.
- Active failures are errors or violations by individuals or teams that directly contribute to an accident.
The Case Report of Vincristine Medication Error
- Illustrates how multiple factors can contribute to a medication error.
- A patient died after receiving vincristine intrathecally instead of intravenously due to a combination of factors, including late patient arrival, similar-looking syringes, and unfamiliar doctor.
- This case highlights the importance of clear communication, standardized procedures, and strong organizational safety culture.
Humans Make Mistakes
- James Reason argues that medication errors often occur due to poorly designed systems.
- He encourages the adoption of a safety culture in healthcare, similar to the approach used in aviation, where errors are expected and systems are designed to compensate for them.
Medication Use Process
- The medication use process involves multiple steps which include: prescribing, transcribing, dispensing, administering, and monitoring.
- Multiple healthcare professionals are involved in each step, including doctors, pharmacists, nurses, and dieticians.
Prescribing Competency Framework
- It's essential to have a good prescribing competency framework to ensure medication safety.
- The Cambridgeshire Enquiry highlighted a tragic case of medication errors leading to a patient’s death.
Medication Error
- A medication error is a preventable event that can lead to inappropriate medication use or patient harm.
- Most errors occur during prescribing and administration, but also during transcribing and dispensing.
Prescribing Errors
- Common examples of prescribing errors include incorrect dosing, drug interactions, illegible handwriting, and electronic prescribing errors.
Risk Management: The Right Medicine
- Taking a complete drug history is crucial for effective prescribing.
- This includes current prescriptions, non-prescription medicines, herbal remedies, and illicit drugs.
- It's important to record any adverse drug reactions and allergies, and to choose the most appropriate medicine.
- The RCSI Essential Medicines resource provides useful information about medications.
Risk Management: Legibility
- Illegible handwriting can lead to medication errors.
Strategies to Reduce SALAD Errors
- Pharmacies should avoid stocking medications with packaging prone to SALAD errors (Sound-Alike, Look-Alike Drugs).
Seven Myths of Human Error
- The "Seven Myths of Human Error" emphasize the need for a system-focused approach to error management.
- This includes recognizing that:
- Errors are not always intrinsically bad.
- People who make errors are not always bad people.
- Errors are not always random.
- Practice does not always make perfect.
- Errors of highly trained professionals are not always rare.
- Errors of highly trained professionals do not always lead to bad outcomes.
- It is easier to change situations than people.
Reason’s Model of Accident Causation
- Reason's model categorizes the causes of accidents into latent conditions, error-producing conditions, and active failures.
- Latent conditions refer to systemic weaknesses or organizational issues.
- Error-producing conditions are factors that influence performance, such as environmental, team, individual, or task factors.
- Active failures are direct errors or violations of rules.
Case Report: Vincristine Medication Error
- This case report highlights a tragic incident where a patient received vincristine intrathecally instead of intravenously, leading to death.
- It demonstrates the importance of clear communication, familiarization with protocols, and proper administration procedures.
“Humans Make Mistakes Because the Systems They Work In Are Poorly Designed”
- This quote by James Reason emphasizes the importance of designing systems to anticipate errors and promote safety.
- Aviation has a strong safety culture based on reporting, shared learning, and designing systems to compensate for human errors.
- Healthcare, in contrast, often has a culture of expecting things to go right and underreporting errors, which hinders learning and improvement.
Error Reduction Strategies
- Implementing a Prescribing Safety Assessment (PSA) is one strategy to improve prescribing skills.
- Patient empowerment for medication safety is crucial for improving medication safety.
Conclusions
- Medication errors are preventable, but the incidence varies due to differing definitions and methodologies.
- Poor prescribing is a major contributing factor to medication errors.
- Addressing medication errors requires a multidisciplinary approach, including improving prescribing skills, creating a supportive safety culture, and promoting reporting of errors for investigation.
