Introduction

Medical errors are committed by health care providers that result in harm to the patients. These errors can occur while:

  • Diagnosing a patient

  • Administrating various medications or transfusions

  • Carrying out laboratory tests

  • Interpreting the laboratory tests

  • Performing some surgical procedures

Medical errors are different from malpractice i.e. medical errors are honest mistakes or accidents while malpractice is the result of negligence or criminal intent. Medical errors are still an important cause of morbidity and mortality worldwide. A comprehensive knowledge about the secrets of medical errors can help the health care provider in preventing the occurrence of these errors. In this regard, proper guidelines issued by the leading institutes of the country and mass education can help the medical professionals to avoid committing medical errors.

The Institution of Medicine (IOM) has published two reports regarding the medical errors and their prevention. These reports are actually a part of the “Quality of Health Care in American” project (a project to access the US health care system). The first report (IOM-1) was published in 1999 and it says that errors by health care providers can be prevented and safety is an important first step in improving the quality of care. The second report was released in 2001 that gave an idea about redesigning of health care system to improve the quality of care. The precious knowledge of these reports will be discussed in this course under different headings in a comprehensive way (1-2).

What is a Medical Error?

A medical error is defined as a preventable adverse effect of care. It may or may not be evident to the patient, and it may be in the form an inaccurate or incomplete diagnosis/treatment of a disease, injury, behavior, infection or other ailment. There are some terms which will be used in the topic, so remember these terms. These include:

  • Safety- means free of accidental injury

  • Adverse event- it is an injury that results from a medical intervention (not due to the underlying disease)

  • Preventable adverse event- an adverse event due to medical error

  • System- a set of interdependent elements working to achieve a common aim

  • Human factor- the study of relationship between humans, instruments and environment (1-2).

What is Impact of Medical Errors on People’s Life and Finance?

According to first report published by The Institution of Medicine (IOM-1), medical errors are responsible for almost 44,000 to 98,000 deaths per year in the hospitals. Medical errors are responsible for harm to one in 10 patients worldwide. Iatrogenic injuries (injuries caused by instruments used or treatment given) are responsible for 180,000 deaths each year. One in five Americans (22%) experienced that they or a family member have suffered a medical error of some type. Medication errors alone are responsible for almost 7,000 deaths per year, about 16% more deaths attributable to work related injuries. Medical errors stand at number 8 among the leading causes of death i.e. even higher than that of motor vehicle accidents or breast cancer. This data was derived from predominately from two studies, one conducted in New York and the other in Colorado and Utah. However, there is controversy regarding the exact magnitude of the adverse outcomes due to medical errors. A 2006, follow up to the IOM study explored that medication errors are among the most common medical errors, affecting at least 1.5 million people every year. This study shows that almost 400,000 preventable drug related harms occur each year in hospital, 800,000 in long term care settings and almost 530,000 among Medicare recipients in outpatient’s clinics.

According to an estimate, these preventable adverse events cost between $17 billion and $20 billion per year. 50% of these costs refer to the direct health care costs like longer stay or treatment. The medication related adverse events in hospitalized patients cost about $2 billion per year.

IOM-1 also brings to light costs that cannot be directly measured, such as:

  • Loss of trust in the system

  • Physical and psychological discomforts for patients

  • Lost work productivity among patients who need extra care

  • Loss of morale and frustrations among health care workers

  • Lower levels of health of the population served

This report also indicates that most of the medical errors do not result from individual recklessness but it is due the basic flaws in the way health systems are organized. Examples of such flaws include:

  • Availability of certain full strengths drugs on patient care units has lead to severe mistakes

  • Illegible writing of prescription resulted in administration of drugs to patients who have known allergies

  • When there is no coordination of care (2-4).

Causes of Medical Errors/Situations prone to Medical Errors

There are many causes of medical errors. These include:

Complexity of health care- toxic drugs, intensive care, complex techniques and prolonged hospital stay all are contributing factors for medical errors

Faulty system and process design- remember that medical errors are not due to bad people in health care settings, it is the bad system of health care that contributes to medical errors. Other contributing factors are:

  • Poor communication of authority of doctors and nurses

  • Unclear lines of authority of doctors and nurses

  • Disconnected reporting system within a hospital

  • Thinking that action is being taken by other groups within the institution

  • Disconnected reporting system

  • Dependence up on automated systems to prevent error

  • Improper systems to share information about errors

  • Infrastructure failure

  • Lack of skilled operators

Human factors and ergonomics

These include:

  • Sleep deprivation of health care providers

  • Risks factors regarding practitioner include fatigue, depression and burn out

  • Factors regarding healthcare settings include variety of patients, unfamiliar settings, tight situations, and burden of patients

  • Similar drugs sound similar

Faults in Competency, education, and training

These include:

  • Diversity in health care provider training and experience

  • Failure to know the severity and prevalence of medical errors

  • Arriving of new residents and nurses at teaching hospitals (2,4,7).

Types of Medical Errors

Remember there are many ways to classify medical errors. Here we have included the classification of medical errors based on IOM-1 report.

Errors regarding diagnosis:

  • Delay in diagnosis

  • Wrong diagnosis

  • Use of outmoded tests

  • Failure to apply the required tests

  • Uses of outmoded therapy

  • Failure to response on results of testing

  • Errors regarding treatment

Errors regarding treatment:

  • Error in performing a procedure, test or surgery

  • Error in administration of drugs

  • Non-significant delay in treatment

  • Inappropriate care which is actually not indicated

Errors regarding prevention:

  • Failure to provide a preventive treatment

  • Improper monitoring of treatment

  • Inadequate follow up

Medication errors

These errors can occur at any stage of drug administration such as during:

  • Ordering the drug- wrong dose or wrong selection of drug

  • Transcribing drug- wrong frequency of drug administration

  • Dispending- drug not provided in time to be administered at the time ordered

  • Administration of the drug- wrong doses, wrong technique of administration

  • Monitoring- no monitoring the drug effects

Adverse drug event

It is any harm or injury that results from a medical intervention related to a drug. Examples are:

  • Cardiac arrhythmias

  • Diarrhea, nausea, vomiting

  • Fever

  • Mental confusion

  • Rash

  • Low blood pressure

  • Liver and renal failure

Other medical errors

These may include:

  • Poor or lack of communication

  • Instrumental failure

  • Other system failure (1,6,7)

What To Do After a Medical Error Has Occurred

  1. Knowing that errors are not isolated events:

There is a strong negative emotional effect of mistakes on the health care providers who commit them. Swiss cheese Model says that adverse events from errors usually do not occur because of an isolated error and these actually reflect system problems. According to this concept, there are layers of protection for health care providers and patients to prevent errors from occurring. If a health care provider makes a small mistake (such as incorrect dose of a drug written on the drug chart by a doctor), this can be picked up (by a pharmacist) before it harms the patient. Such mechanisms are:

  • Practical alterations such as medications which are not given by IV route, must be fitted with tubing.

  • Systemic safety processes- Water low score assessment and falls assessment of all the patients must be completed on admission

  • Training programs (5,7,8).

  1. Keeping the practice of medicine in perspective:

The potential to make errors is part of what makes a physician rewarding and without this potential the rewards of medical care would be less.

  1. Mistakes Disclosure

  • Disclosure to oneself- if you have no ability to forgive one self, it may create a cycle of restlessness and thus increases the chances of a future error.

  • Disclosure to patients- it is very important to disclose to patients whenever a medical error has occurred. The American Medical Association's Council on Ethical and Judicial Affairs says in its ethics code:


"Situations occasionally occur in which a patient suffers significant medical complications that may have resulted from the physician's mistake or judgment. In these situations, the physician is ethically required to inform the patient of all facts necessary to ensure understanding of what has occurred. Concern regarding legal liability which might result following truthful disclosure should not affect the physician's honesty with a patient."

Similarly, “The American College of Physicians Ethics Manual” remarks as:

“In addition, physicians should disclose to patients information about procedural or judgment errors made in the course of care if such information is material to the patient's well-being. Errors do not necessarily constitute improper, negligent, or unethical behavior, but failure to disclose them may.”

  • Disclosure to non-physicians- recent studies show that disclosing to non-physicians sources of support may decrease the pressure more than disclosing to colleagues.

  • Disclosure to other physicians colleagues- telling about your errors to other doctors is beneficial even with a fact that doctors may be less forgiving of each other (5,7,8).

  • Telling to the doctors’ institution

  • Use of rationalization to hide medical errors

How to Reduce/Avoid/Prevent Medical Errors

Following steps are important in reducing/avoiding/preventing medical errors:

  1. Make a center for patient safety within the agency for health care research and quality

    • This center should perform following functions:

      • Make national goals for patient safety

      • Follow the progress in the meeting for the recognized goals

      • Create knowledge and understanding of mistakes in health care by developing a research agenda

  2. Form mandatory and voluntary reporting systems regarding collection and interpretation of medical mistakes

  3. Make the standards and expectations for improvement in safety high via the actions and support of oversight organizations

  4. Make safety systems inside the healthcare organizations via the use of safe practices at the delivery level

  5. Make an accurate patient’s identification

  6. Increase the effectiveness of communication among the patients and the providers

  7. Timely reporting of important tests

  8. Label all the medications

  9. Transfer accurately the medication information to nurses

  10. Fulfill the hand hygiene guidelines and thus decrease the risk of infection

  11. Make a universal agenda for preventing wrong site, wrong patient and wrong procedure

  12. Complete the pre-procedure verification

  13. Ensure the safe place for medication preparation

  14. Reduce interruptions during drug administration

  15. Use calculator to calculate the exact dose

  16. Separate and label of drugs with similar names, colors or sounds

  17. Check whether medication is given to proper patient

  18. Nursing education regarding calculation of dose

  19. Delivery of drugs from pharmacy to ward under supervision of staff nurse

  20. Double checking of medications via two separate nurses

  21. Follow the rule of right i.e. right patient, right drug, right dose, right route and right time

  22. Head nurse must report the medication error when it occurs

  23. Nurses must have access to patient’s information

  24. Increase the patient-nurse ratio in each shift

  25. Attendance of educational programs

  26. Make medication administration policy (5,9,10).
