Medical errors in healthcare rank among the leading causes of preventable death. According to the WHO, 1 in 10 patients experience preventable harm while receiving care. and the financial fallout can be severe. Malpractice risks increase, compliance pressure grows, reimbursement is delayed or denied, and rebuilding patient trust can take years.
So what actually counts as a healthcare error? Healthcare errors are preventable breakdowns resulting from failure in medical care, such as incorrect, delayed, or omitted actions during diagnosis, treatment, or patient management.
Understanding where these errors start is the first step to stopping them. So, let’s have a look at what medical errors are, how they occur, and how healthcare organizations can reduce them.
What are Medical Errors
Medical errors are preventable adverse events that stem from failures in planning or execution of care. These errors can be caused by individual clinicians, technology systems, or institutional policies.
An observational study 1 in 14 patients in general medical hospital units experienced harmful diagnostic errors. Therefore, inaccurate documentation is one of the most common contributors to preventable healthcare errors, particularly when clinical notes are incomplete or delayed.
Understanding 7 Root Causes of Medical Errors
Learning about the reasons behind medical errors is the first step towards improving patient safety and reducing operational risks.
Diagnostic errors
Diagnostic errors are failures to provide accurate and timely explanations about patient healthcare. Common forms of diagnostic errors include:
Misdiagnosis
Misdiagnosis is the failure to accurately and timely identify a patient’s health condition. It can lead to delayed or inappropriate treatment.
It happens when clinicians are under high pressure from administrative tasks, have limited consultation time, or have incomplete patient information. The growing non-clinical workload has made this issue more common, as the administrative burden has increased paperwork.
Delayed diagnosis
Delayed diagnosis occurs when the correct issue is identified but not within the necessary time period. Unfortunately, delayed diagnosis usually results in a worsening condition of the patient, even if it can cause the death of the individual.
A delay in diagnosis happens due to misinterpreting test results, failing to carry out appropriate tests, or not recognizing the severity of symptoms.
Failure to order tests
Failure to order required tests like blood tests, biopsies, and imaging by a doctor can have a negative impact on both patient health and healthcare practices.
When necessary testing is delayed, diagnosis can be too late for a crucial treatment. For example, a missed cancer diagnosis can progress to a terminal stage, and an untreated infection may lead to severe complications. These failures not only harm patients but can also cause compliance and liability risks for practices.
Communication breakdown
When information is not clearly shared among providers, staff, or patients, it can easily cause a communication gap.
Misunderstood instructions, incomplete handoffs, and missing updates in patient records can lead to treatment delays and medication mistakes. It affects patient safety and continuity of care.
Effective coordination between providers and support staff reduces diagnostic delays. Many practices use patient care coordination support to avoid such delays and keep communication clear.
Medication errors
Medication errors are very common and refer to preventable mistakes that occur during prescribing, dispensing, or administering medications.
For example, giving the wrong dose, missing harmful drug interactions, incorrectly transcribing prescriptions, or providing medication at the wrong time or frequency.
Wrong dosage
Due to incomplete records or unclear medicine prescriptions, patients take medicine more than it was required or less than suggested. It can cause serious health hazards like adverse side effects or treatment failure.
Drug interactions
Drug interaction is a reaction that occurs when two or more drugs react with each other, or when a drug reacts with a beverage, food, or supplement. These interactions can alter how a medication can work, potentially making it less effective or triggering unexpected side effects.
Prescription transcription mistakes
Prescription transcription mistakes occur when medication orders are transferred incorrectly from one system to another. For example
For example, when handwritten prescriptions are misread, verbal instructions are misheard, or electronic entries are mistyped. Even a small mistake of a single decimal missing can pose a serious threat to patient health. Clear clinical documentation support can help reduce these risks by ensuring medication and insurance details are accurately recorded, reviewed, and verified before processing.
Administration timing errors
Administration timing errors occur when a medicine is given at the wrong time, impacting its effectiveness on a patient’s health.
For example, an insulin wrongfully prescribed in terms of units and time (right before having a meal) may trigger fluctuations in blood glucose levels. These errors not only pose serious health issues to patients but can also increase potential liability risks for healthcare practices.
Surgical and procedural errors
Errors that occur before, during, or after medical procedures and cause serious harm to patients are relevant to surgical and procedural errors. It can be a wrong-site surgery, where surgery is performed on an incorrect part of the body.
Wrong-site surgery
Due to surgical and procedural errors, a surgery performed on the wrong part of the body is one of the most serious concerns.
For example, in a general surgery setting, there is an extremely small margin for documentation errors. That’s why it’s a common practice to work with a virtual assistant for general surgery to avoid these serious errors.
Retained surgical items
Think about it this way: an error that increases the risk for a patient where sponges, towels, or instruments are left inside a patient`s body after incision closure. It happens due to rushed counts, staff changes during surgeries, or distractions in the operating room.
Because of these errors, repeat surgeries are performed to remove objects and practices that bear higher legal risks.
Anesthesia mistakes
When anesthesia is given or monitored incorrectly, it can cause some problems in the patient’s condition post-surgery. These errors occur due to wrong dosage, delayed airway management, and poor monitoring of vital signs like oxygen level and heart rate. It can affect the nervous systems which can cause serious complications like brain injury, organ damage, or even death.
Communication errors
Communication errors occur when patient information is not clearly delivered to providers or other medical staff.
Miscommunication between staff
Miscommunication between staff members occurs when instructions or patient information are unclear or not properly shared among healthcare providers. It can lead to missed follow-ups or delayed care.
Accurate intake and scheduling processes reduce communication breakdowns at the administrative level. Partnering with experienced medical front desk professionals ensures that patient data is acquired correctly. This support can reduce miscommunication among staff and reduce burnout as well.
Poor handoffs
Poor handoffs happen when critical information about patients is not properly shared when one healthcare provider hands over care to another. For example, during shift changes or patient transfers, key details about patients are missed. It can lead to delays in treatment or medical mistakes.
Incomplete chart updates
Incomplete chart updates occur when patient records are not updated with the latest test results, treatment changes, or clinical notes, causing providers to rely on outdated information.
EHR misinterpretation
EHR misinterpretation happens when information in electronic health records is misunderstood, overlooked, or difficult to locate, even though it has been correctly documented.
Documentation errors
Another one of the common errors in healthcare is incomplete healthcare records, leading to some serious documentation errors.
Incomplete charting
If the details about allergies or the treatment of a patient are missing, it can create gaps in care. Incomplete charting can be responsible for an increasing risk of medical errors and claim denials.
Copy-paste errors
Copy-paste errors occur when incorrect information is used for other future records. Even a small mistake or a typing error can be copied into later visits and become part of the patient’s permanent record.
Because the chart appears complete, clinicians may not notice the error. This small error can lead to misdiagnosis, duplicate tests, or harmful drug interactions. To ensure accuracy, many practices prefer a dedicated medical scribe to make detailed notes, minimizing mistakes early.
Late entries
Late entries occur when patient details are added later after the visit. So, when entries are done late, it means details were not available at the time decisions were made. It can create confusion, weaken clinical accuracy, and increase compliance or legal risks.
EHR usability issues
EHR has complex layouts, requires too many clicks, or has unclear fields. It can cause staff to miss information or skip documentation, increasing the risk of errors and incomplete patient records.
These workflow disruptions are often caused by EHR interoperability challenges, as EHR systems do not communicate well with each other. When healthcare practitioners have to switch to different systems to obtain patient information, it can cause error risks.
System errors in healthcare
System errors are operational errors that impact patient care, efficiency, and revenue.
Inadequate staffing ratios
When there are too few nurses, physicians, or administrative staff to care for the patients. The work becomes rushed and fragmented. Providers may skip documentation steps or keep them pending, causing important details of patients to be missing. Working for more than the shift time increases burnout, which causes overall error rates.
Poor training systems
Practices that hire untrained staff are more likely to face more medical errors than those that prefer trained staff or train them, offering different programs. This leads to inconsistent practices, avoidable claim denials, and patient safety risks.
Lack of standardized templates
When documentation formats vary from provider to provider, important clinical or billing details can be missed. Standardized templates help ensure that allergies, medications, vitals, and treatment plans are consistently recorded. It reduces gaps in care. Insurance verification issues
Delayed billing submissions
Submitting claims late increases the risk of timely filing denials. These delays cause disruption in cash flow, extend accounts receivable cycles, and create additional workload for billing teams.
System-level gaps in revenue cycle processes can also contribute to financial and compliance risks, making it important for medical billing specialists to monitor and optimize billing workflows.
Administrative and billing errors
Administrative and billing errors can have a direct impact on cash flow and audit risk of your organization. So, keep in mind that even small mistakes can delay your payments.
Incorrect coding
When codes like CPT, ICD-10, or HCPCS are incorrectly added, payments are affected. For example, you may get underpaid, face delayed payment, or even no payments. When your facility repeats mistakes, it can trigger audit risks or a fraud investigation.
To avoid this error, practices can prefer revenue cycle support professionals who can handle insurance follow-ups and coding review processes. They can assure you that claims are accurate and compliant.
Claim denials
According to a journal, lack of proper documentation can cause almost 20% claim denials. Its a further proof that incomplete or inaccurate claims are often the reason behind delayed reimbursement.
Missing patient demographics
It happens when your staff is busy dealing with too many tasks. Due to this workload, they add incomplete or incorrect patient information, which causes immediate claim rejection or delay in billing.
Eligibility verification failures
If your clinical staff does not verify insurance coverage of patients, the risk of claim denial increases. If the coverage is inactive, or there is a missing prior authorization, but your staff did not check. This mistake can turn your facility into debt that impacts the revenue of your organization.
5 Root Causes Behind Healthcare Errors
Clinical errors stem from systemic, organizational, and human factors rather than individual negligence.
Human factors (fatigue, burnout)
A staff member who works for hours gets fatigued, which may lead to staff burnout. Due to this burnout, there are chances of medical errors. To address this workload strain, many healthcare practices evaluate staffing models, including operational structures such as nearshore support teams, to hire talent that would help reduce administrative pressure and maintain the quality of their workflows.
Technology limitations
The main objective of electronic health records (EHRs), billing software, and clinical systems is to improve safety. But if they are poorly designed, they can contribute to missed alerts, documentation gaps, and user frustration.
Workflow inefficiencies
Inefficient processes such as unclear handoffs, redundant data entry, or poorly defined approval chains slow down care. They increase the chance that important details will be missed. Workflow inefficiencies can lead to higher error rates.
Inadequate training
Without consistent onboarding and ongoing education, staff may misunderstand compliance requirements or safety protocols. Their knowledge gaps can have a worse impact on documentation accuracy, billing performance, and patient care quality.
Lack of accountability systems
When organizations do not have a proper accountability system, they cannot trace mistakes. In this way, small errors keep happening again and again. For example, patient information may be added incorrectly again and again due to the absence of an accountability system. If you implement an accountability system, these errors can be significantly reduced.
What is the Impact of Healthcare Errors
Healthcare gaps have profound impacts on patients and organizations. They can have clinical, financial, and compliance impact.
Clinical Impact
Patient Harm: Healthcare errors can have worse repercussions on patient health. For example, these errors can lead to infection, disability, or even death.
Delayed Treatment:
Delayed treatment can be harmful for an individual who needs immediate treatment but couldn’t get it. It can lead to severe risks to human life.
Increased Mortality Risk:
Medical errors are a serious threat to patient safety and may lead to death. For example, if a patient is misdiagnosed at your hospital, he may have serious life concerns.
Extended Length of Stay: If patients are not treated on time, their condition can become worse. It can cause a longer stay at hospital due to complications.
Financial Impact
Malpractice Costs: If errors are prolonged, claims and legal settlements can significantly increase operational expenses.
Claim Denials: Inaccurate or incomplete documentation often results in denied claims and delayed reimbursements.
CMS Penalties: Programs from the Centers for Medicare & Medicaid Services may reduce payments for hospitals with high readmission rates or hospital-acquired conditions.
Rework & Administrative Burden: Correcting errors consumes staff time and increases overhead costs.
Compliance Impact
Medical mistakes can trigger regulatory scrutiny and long-term reputational harm.
HIPAA Risks: Errors in documentation are violations of HIPAA. It is compulsory to follow U.S. healthcare workflow protocols, and failure to do so results in an increase in claim denials.
Audit Exposure: Errors can trigger external audits by organizations like CMS, Recovery Audit Contractors (RACs), or commercial payers. It can increase administrative burden and financial recoupment risk.
Reputational Damage: Your organization can face severe repercussions due to reputational damage. For example, it can erode patient trust, leading to reduced patient volume.
How Healthcare Organizations Can Reduce Errors
You cannot eliminate human errors, as making mistakes by humans is obvious. But healthcare organizations can build systems that can reduce these errors.
Standardized protocols
Standardized protocols are a good approach to reducing medical errors. Organizations can make a proper checklist for every patient so they make sure nothing is skipped. This initiative can reduce confusion and lower the chances of mistakes.
Improved EHR optimization
You can work for the betterment of an electronic health record (EHR) system. A better system can reduce alert fatigue, and simplified interfaces help staff focus on essential information. It can also assist staff in completing documentation accurately.
Strong documentation practices
Accurate and timely documentation is crucial for both patient safety and compliance with your practice. Well-maintained documents can encourage real-time charting and limit unnecessary copy-paste practices. Additionally, practices can also conduct regular chart audits, help identify errors early, and maintain reliable records.
Clear role allocation
Healthcare facilities can also reduce these gaps by clearly defining the responsibilities of their staff. In this way, they can prevent tasks from being overlooked or duplicated. When staff understand the importance of healthcare administrative specialists and their accountability, workflows become more efficient, and care coordination improves.
Continuous staff training
Another way to reduce administrative burden is to provide staff training. It can help staff to stay updated on protocols, technology changes, and safety practices. Short and regular training sessions can help teams perform their tasks efficiently without making any mistakes.
Internal audits & reporting systems
Organizations can encourage reporting of near-misses and errors without blame. Tracking incidents, analyzing patterns, and implementing corrective actions allow teams to learn from mistakes and prevent them from recurring.
Take the First Step to Prevent Healthcare Errors in Your Practice
It is important for all healthcare practices, of any size, to prioritize training for their in-house staff to eliminate errors in their workflows. You can do so by training your team to have firsthand experience on how to engage with patients and ensure correct medical details are recorded.
Also, you can reduce the burden of documentation, scheduling, and follow-ups by onboarding the best virtual assistants from remote staffing agencies. They ensure to provide compliant talent who readily integrate strategies into your existing systems at a fraction of the traditional costs.
