Medical errors


Many individuals rarely consider the prospect of medical errors in their everyday existence. Unless directly experiencing the repercussions of a medical mistake, the notion that it could affect one's own life might appear distant. However, it prompts the question: is this assumption entirely accurate?

As outlined in the 2019 World Health Organization (WHO) Patient Safety Factsheet, incidents resulting from unsafe patient care rank among the globe's leading causes of death and disability.

Notably, preventable adverse events within the United States of America (US) contribute to a significant toll, causing an estimated 44,000 to 98,000 deaths annually within hospital settings, underscoring the profound impact of patient safety challenges on a global scale.

Common Causes of Medical Errors 

Medication Errors

Medication errors, acknowledged as the most prevalent and avoidable source of patient harm, encompass a spectrum of missteps.

This includes administering the wrong drug or dosage, utilizing an incorrect route, mistimed administrations, or even delivering medication to the wrong patient.

In acute hospitals, the reported incidence of medication error-related adverse events hovers at approximately 6.5 per 100 admissions. Of particular concern are errors occurring in the peri-discharge phase, often overlooked but carrying significant implications.


Diagnostic Dilemmas

Diagnostic errors pose a formidable challenge, reflecting a failure to promptly and accurately pinpoint the underlying cause of a clinical condition. Characterized as missed opportunities to make a correct or timely diagnosis based on available evidence, these errors transcend the immediate harm to patients.

Preventable Mishaps in Hospitalized Patients

Hospitalized patients face a spectrum of preventable errors, encompassing wound infections, pressure ulcers, falls, healthcare-associated infections, and technical complications. These incidents, while potentially avoidable, underscore the need for enhanced vigilance and systemic improvements in patient care.

Communication Breakdown

A common systemic error manifests in the failure to disseminate crucial drug knowledge and patient information, resulting in communication lapses with both patients and fellow healthcare providers.

This points to a critical area where improvements are needed to enhance patient safety.

Testing Troubles: Errors in Diagnostic Procedures

Failure to employ indicated tests or using outdated procedures can lead to diagnostic delays or errors, posing a significant risk to patient well-being.

Additionally, neglecting to respond promptly to test results or monitoring further compounds the potential for medical errors, necessitating a closer look at procedural adherence.

Treatment Error

Treatment errors, occurring during the execution of tests or procedures, as well as instances of inappropriate treatment, constitute another facet of medical errors.

This necessitates a meticulous examination of healthcare practices to ensure patient safety remains at the forefront of medical care.

Most Frequent Medical Errors  Category

Common medical errors
  1. Diagnostic Error:

 Misdiagnoses, failures to diagnose, and delayed diagnoses emerge as pervasive medical errors. Factors such as overlooked diagnostic tests, misinterpretation of results, and insurance-related limitations contribute to this unsettling trend.

  1. Medication Error:

 Medication errors, a prevalent concern, encompass instances where physicians prescribe incorrect doses or the wrong medications. Nurses, pharmacists, and defective medical devices also play roles in administering incorrect medicines or doses, further jeopardizing patient safety.

  1. Surgical Error: 

Operating room mishaps cast a shadow on patient well-being, with instances of operating on the wrong site or performing the incorrect surgery. Grave consequences include amputations of the wrong limb and leaving instruments inside patients.

  1. Labor and Delivery:

 Inadequacies during labor and delivery expose mothers and babies to peril, ranging from improper use of tools causing scarring to delayed C-sections and insufficient vital sign monitoring leading to birth injuries.

  1. Anesthesia Anxieties:

Anesthesia errors, if not vigilantly managed, can lead to brain damage, wrongful deaths, and permanent disabilities. The intricacies of balancing oxygen levels and medication pose critical challenges for anesthesiologists.

  1. Informed Consent Lapses:

Patients' right to informed consent is a cornerstone, demanding comprehensive explanations from doctors about procedures, risks, and alternatives. The failure to obtain informed consent raises ethical and legal concerns.


  1. Communication Breakdowns:

 Communication lapses among medical professionals can have profound consequences, potentially resulting in incorrect treatments or missed diagnoses. Patient well-being is compromised when critical information fails to traverse the healthcare network.

  1. Infections and Complications:

Hospital-acquired infections, often stemming from lapses in sanitation and hygiene protocols, present life-threatening conditions like sepsis. Failure to monitor patients can lead to infections and subsequent complications, underscoring the critical importance of attentive care.

In the pursuit of healing, the healthcare system grapples with these pervasive issues, emphasizing the urgent need for comprehensive reforms and heightened vigilance to safeguard patient welfare.

Recent Medical Errors That Made the News(2023)

Adventist Health Simi Valley faced scrutiny after an 81-year-old patient's fatal medication error. Two doses of Lovenox within two hours caused a brain bleed, deemed a "system-wide failure" by the state.

Physician order lapses, communication failures between pharmacies, and overlooked dose adjustments were highlighted. The hospital addressed concerns, lifting the "immediate jeopardy" label in May. 

Northridge Hospital Medical Center faced similar criticisms, rectifying deficiencies and lifting its label.

Both reviews, authorized by Centers for Medicare & Medicaid Services, haven't indicated potential fines. The hospitals stress commitment to safety and preventive measures.


According to news an anesthesiologist, Dr. Dmitry Shelchkov, committed a critical error during a routine epidural procedure for pregnant Sha-Asia Semple at Woodhull Medical Center in Brooklyn.

Dr. Shelchkov, who later lost his medical license, inserted the catheter excessively, causing anesthesia to enter Ms. Semple's cerebrospinal fluid.

She tragically died, prompting public outrage and highlighting racial disparities in maternal mortality.

In the two years leading up to her death, six other pregnant patients experienced adverse outcomes related to anesthesia at Woodhull, with Dr. Shelchkov implicated in most cases.

Despite the pattern, hospital administrators failed to monitor him adequately, revealing dysfunction at Woodhull, a public hospital catering to vulnerable mothers, mainly Black and Hispanic, with a majority on Medicaid.
