The nature of medical errors and diagnostic Improvement opportunities

The ease with which medical errors can occur is alarming. Here are just a few striking examples of avoidable mistakes that should never happen:

• In New Mexico, a doctor intended to perform a bronchoscopy to remove a sunflower seed lodged in a 2-year-old’s airway. Instead, he inadvertently sedated the boy with an adult dose of morphine, causing him to stop breathing and suffer severe, permanent brain damage.

• A lab in New York state mislabeled a tissue sample, leading to a woman without breast cancer undergoing a double mastectomy while the cancer in another woman went untreated.

• Surgeons still confuse left and right, and patients often receive the wrong medication or dosage. This was tragically the case for Boston Globe health reporter Betsy Lehman, who died from a miscalculated overdose of chemotherapy drugs.

These incidents highlight the critical need for improved safety measures in healthcare.

The nature of medical errors

Common adverse events leading to avoidable patient harm include medication errors, unsafe surgical procedures, healthcare-associated infections, diagnostic errors, patient falls, pressure ulcers, patient misidentification, unsafe blood transfusions, and venous thromboembolism. The World Health Organization highlights alarming facts:

• 1 in 10 patients is harmed in healthcare, resulting in over 3 million deaths annually due to unsafe care. In low-to-middle-income countries, 4 in 100 people die from unsafe care.

• More than 50% of harm (1 in 20 patients) is preventable, with medications responsible for half of this harm.

• Estimates indicate that 4 in 10 patients are harmed in primary and ambulatory settings, with up to 80% of this harm avoidable.

• Patient harm could reduce global economic growth by 0.7% each year, costing trillions of US dollars globally.

These statistics underscore the urgent need for action to enhance patient safety and reduce medical errors.

Where can biomedical engineering play a part in the solution

Biomedical engineering is revolutionizing the fight against medical errors with innovative solutions tailored to common pitfalls. Here’s how it tackles key issues:

1. Diagnostic Errors

Biomedical engineers are at the forefront of enhancing diagnostic accuracy and speed:

• AI and Machine Learning: Cutting-edge algorithms for precise image analysis, like cancer detection in radiology.

• Point-of-Care Devices: Portable tech for quick, accurate diagnostics—think glucose monitors and infectious disease tests.

• Wearable Technology: Continuous monitoring of vital signs to catch conditions like arrhythmias or sleep apnea before they escalate.

2. Medication Errors

Engineering innovations are crucial in preventing medication mishaps:

• Smart Infusion Pumps: Automatically manage dosages and flag incorrect settings.

• Barcoding Systems: Ensure the right meds reach the right patients every time.

• Automated Dispensing Cabinets (ADCs): Slash human error in medication distribution.

• Pharmacy Robots: Precision-filling prescriptions to eliminate dispensing errors.

3. Surgical Errors

Biomedical engineering is enhancing surgical precision and safety:

• Robotic Surgery Systems: Elevate precision and minimize invasive errors.

• Image-Guided Surgery Tools: Real-time imaging to prevent wrong-site surgeries.

• Surgical Navigation Systems: GPS-like guidance for surgeons to ensure accuracy.

• Sensor-Equipped Surgical Instruments: Provide haptic feedback and real-time data to avert mistakes.

4. Communication Failures

Technology is bridging communication gaps in healthcare teams:

• Electronic Health Records (EHRs): Advanced systems with decision support and alerts for seamless care.

• Secure Messaging Platforms: Real-time communication among healthcare professionals.

• Clinical Decision Support Systems (CDSS): Evidence-based recommendations to empower clinicians.

These advancements are not just improvements; they are game-changers in the quest for safer healthcare.

The Future of Healthcare to prevent harm

Varied causes demand varied solutions. A standout success story comes from anesthesiology. Anesthesiologists scrutinized the mistakes leading to lawsuits and developed robust procedures and tools for safer practices. As a result, the incidence of deaths from general anesthesia plummeted from over 1 in 5,000 patients in the 1950s through the 1980s to as low as 1 in 250,000 by 2000 — a staggering 50-fold improvement. Yet, other specialties have struggled to achieve similar advancements.

1. Digital Twins: Virtual patient models for simulating treatments and outcomes.

2. Personalized Medicine: Customized treatments leveraging genomic data and wearable tech.

3. Augmented Reality (AR) in Surgery: Overlaying critical information during procedures.

The potential for these solutions is immense, and their popularity is set to soar in the near future. Biomedical engineering, powered by AI, holds tremendous promise for enhancing patient safety and slashing errors.
