Common Types of Diagnostic Errors

Understanding Diagnostic Errors

When you visit a doctor or hospital in California, you trust that your symptoms will be carefully evaluated. Unfortunately, diagnostic errors are a leading cause of medical malpractice claims, often resulting in serious harm. Knowing the types of mistakes that happen during the diagnostic process can help you recognize if you or a loved one has been affected—and what steps you can take next.

What Diagnostic Errors Mean

Diagnostic errors occur when a medical provider fails to identify a health problem accurately or in a timely manner. This can include missing the real cause, making an incorrect diagnosis, or failing to spot a related condition. In California, these errors may lead to delayed treatment, unnecessary procedures, or even life-threatening complications.

Common Causes in California

The most frequent types of diagnostic errors seen in California medical malpractice claims include:

• Missed diagnosis: The provider fails to detect a medical issue entirely.
• Delayed diagnosis: The correct diagnosis is made, but only after a harmful delay.
• Misdiagnosis: The provider identifies the wrong condition.
• Failure to recognize complications: Related health issues are overlooked.
• Failure to diagnose related diseases: Secondary or concurrent illnesses are missed.

These mistakes can happen in hospitals, clinics, and even during emergency care.

State and Federal Law Protections

California law protects patients from harm caused by diagnostic mistakes. Under the Medical Injury Compensation Reform Act (MICRA), you have two years from the date you discover the error to pursue a claim. Federal regulations, including Medicare requirements, set additional standards for hospitals and clinics. Both state and federal rules require healthcare providers to follow accepted medical practices.

Missed Cancer Diagnoses

One of the most devastating types of diagnostic errors is failing to identify cancer. Missing or delaying a cancer diagnosis can allow the disease to progress, often reducing treatment options. California courts frequently see claims related to undiagnosed breast, lung, and colon cancer. If you have suffered from a diagnostic mistake involving cancer, it is important to understand your legal rights.

• Commonly missed cancers:
  • Breast cancer
  • Lung cancer
  • Colon cancer
  • Prostate cancer
  • Skin cancer

Heart Attack and Stroke Errors

Heart attacks and strokes are sometimes confused with less serious conditions. In emergency rooms, these errors can be deadly. Failure to recognize symptoms like chest pain, numbness, or slurred speech may result in inadequate care. Emergency diagnostic errors are a significant issue throughout California.

Infections That Go Undiagnosed

Sepsis, meningitis, and other serious infections require quick identification. A missed or delayed diagnosis of an infection can lead to permanent injury or death. California hospitals have protocols for infection detection, but lapses still occur—especially in busy settings.

• Frequent infection errors:
  • Missed sepsis
  • Undiagnosed meningitis
  • Misidentified urinary tract infections
  • Delayed pneumonia diagnosis

Diagnostic Imaging Mistakes

X-rays, MRIs, and CT scans are critical for accurate diagnoses. Errors can occur if a scan is not ordered, is misread, or results are not communicated to the treating physician. Imaging errors are often cited in medical malpractice lawsuits.

• Imaging-related mistakes:
  • Not ordering the correct test
  • Misreading scan results
  • Failing to follow up on abnormal findings

Lab Test Errors

Lab tests help confirm or rule out certain conditions. Diagnostic mistakes happen when tests are misinterpreted or when abnormal results are overlooked. This can delay vital treatment, especially for conditions like diabetes or infections.

• Common scenarios:
  • Lost or mixed-up samples
  • Incorrect interpretation of bloodwork
  • Failure to act on abnormal results

Communication Breakdowns

Diagnostic errors often stem from poor communication between providers, especially during shift changes or when care is transferred between specialists. Lack of clear instructions or incomplete records can cause crucial information to be missed.

• Communication lapses:
  • Incomplete handoff notes
  • Missing discharge instructions
  • Unclear follow-up plans

Pediatric Diagnostic Errors

Children present unique diagnostic challenges because symptoms can be subtle or mimic other illnesses. Missed appendicitis, infections, or congenital conditions are common in pediatric malpractice cases in California.

• Typical pediatric errors:
  • Undiagnosed appendicitis
  • Missed meningitis
  • Failure to recognize congenital disorders

Elderly Patients at Higher Risk

Older adults may have multiple health issues, making diagnosis more complex. Overlapping symptoms or assumptions about “normal aging” can lead to missed diagnoses in California’s aging population.

• Risks for seniors:
  • Overlooking heart problems
  • Misattributing confusion to dementia
  • Missing medication side effects

Steps You Can Take

If you suspect a diagnostic error, consider the following:

• Gather all medical records and test results.
• Request a second opinion from another provider.
• Keep a journal of symptoms and interactions.
• Reach out to an attorney experienced in medical malpractice claims.
