If 99.9% Is Good Enough…Reframing Health Care Quality and Safety
In health care, 99.9% sounds exceptional, until you unpack what that remaining 0.1% represents. Applied to modern hospitals, it means nearly 1 in 1,000 patients could experience serious harm. Across a facility with 1,000 inpatients who each receive four medications three times daily, that tiny margin translates to ~4,000 medication errors each year https://www.hkmj.org/system/files/hkm0202p65.pdf
Globally, the stakes are even higher. The World Health Organization estimates that 1 in 10 patients is harmed while receiving hospital care, resulting in over 3 million deaths annually– and more than half of this harm is preventable https://www.who.int/news-room/fact-sheets/detail/patient-safety In high-income countries alone, preventable harm occurs in 10% of hospitalizations, with low-to-middle-income nations suffering even worse outcomes https://www.who.int/news-room/fact-sheets/detail/patient-safety

In the U.S., the picture is equally troubling:
- Medical errors rank as the third leading cause of death, with estimates ranging from 210,000 to over 400,000 deaths annually due to preventable harm in hospitals https://pubmed.ncbi.nlm.nih.gov/23860193/
- Hospital-acquired infections impact 1 in 31 patients, contributing to approximately 99,000 deaths each year https://en.wikipedia.org/wiki/Hospital-acquired_infection
- Nearly 250,000 U.S. inpatient deaths each year are attributed to medical errors, accidents, injuries, or infections which are all events hospitals should prevent https://www.leapfroggroup.org/
- From a global lens, the indirect cost of patient harm equals 0.7% of GDP every year- measured not just in lives but also in lost economic potential. https://www.who.int/news-room/fact-sheets/detail/patient-safety
Progress Is Real, But Incomplete
There are bright spots of progress:
- In Spring 2025, 12% of U.S. hospitals have maintained an “A” safety grade across five or more Leapfrog evaluations https://www.leapfroggroup.org/
- The American Hospital Association reports 13 million patients noting improved care experiences, while 1.7 million clinicians indicate better safety cultures post-pandemic https://www.aha.org/news/headline/2025-03-12
However, new threats emerge weekly:
- Dismissing patient and family concerns ranks as the #1 patient safety issue, with 55% of dismissed patients reporting worsened outcomes and 28% suffering health emergencies- —underscoring the urgent need for better communication https://www.beckershospitalreview.com/quality/patient-safety-outcomes
- Equipment malfunctions in the NHS led to nearly 4,000 incidents and 87 deaths between 2022 and 2025, an internationally alarming warning bell https://www.theguardian.com/society/2025/jun/09

Small Failures, Big Consequences
We often aim for perfection, but small failures accumulate rapidly. A 0.1% error rate in medication translates into thousands of errors annually. Even barcode verification systems, proven to prevent 90,000 serious errors a year, are underutilized, despite reducing administration mistakes by 82% https://en.wikipedia.org/wiki/Barcode_technology_in_healthcare
Likewise, widely adopted computerized order entry can reduce medication errors by 80% and serious harm by 55% https://en.wikipedia.org/wiki/Computerized_physician_order_entry
Why 99.9% Isn’t Good Enough
Because in health care, every percentage point lost equates to lives, fear, and opportunity:
- Thousands injured or killed annually due to preventable errors
- Millions facing harm from infections, misdiagnoses, falls, or overlooked concerns
- Trillions lost, when you factor in global productivity and economic drag
Redefining “Good Enough”
Health care needs to shift its mindset:
- Reframe endpoints: From efficiency to zero avoidable harm
- Embed accountability: Track errors, learn from them, and implement systemic fixes
- Invest in proven tools: Barcode scanning, CPOE, AI-predictive analytics are proactive investments that save lives and dollars
- Center families and patients: Open communication and partnership are critical to preventing harm https://en.wikipedia.org/wiki/Patient_safety

The Invitation
Let’s challenge complacency: 99.9% isn’t enough. When 0.1% means thousands of lives lost, we must strive for zero avoidable harm. Safe care is not aspirational…it’s essential.
At CHCM, we’re partnering with health systems to redesign culture, systems, and strategy, so they don’t just aim high, they hit zero harm. If you’re ready to elevate beyond “good enough,” let’s connect. Health and humanity depends on it.
