Key points
  • In the U.S., studies such as those from Johns Hopkins University point out that "medical errors rank among the leading causes of death" (estimates are roughly 250,000–440,000).
  • Medical errors are not just "individual mistakes" but often stem from system flaws, staffing shortages, and poor information sharing.
  • In Japan there is a reporting system, but because it is largely self-reported and there are concerns about concealment, the true situation is not fully understood.
  • What patients and families can do: ask questions, clearly state medications and allergies, seek second opinions, carry records, and other actions can reduce risk.

Introduction: A reality we'd rather cover our ears to, but can't ignore

What we expect from medical care is to be able to "trustingly leave our care in others' hands." However, looking at research presented by Johns Hopkins University in 2016 and estimates compiled by John T. James in 2013, we have to acknowledge that the harm from medical errors exists on a scale that cannot be ignored. To be honest, I was shocked when I first saw these numbers, but I feel that knowing the facts is the first step toward improvement. In this article we will clearly explain cases, background factors, and the practical measures we can take in daily life.

What is happening in modern medicine: the dangers seen through cases

A tragic example — Emily and James' son

Some reports from overseas are heart-wrenching. One-and-a-half-year-old Emily lost her life due to excessive medication. It is said that pharmacist dispensing errors, miscalculation of dosages, and that day's understaffing and system failures combined. In another case, a 19-year-old was diagnosed with arrhythmia but did not receive appropriate follow-up and suffered sudden death. These cases show structural problems that cannot be dismissed as mere "bad luck" or "individual failures."

How often does this happen?

Johns Hopkins University's research placed medical errors among the leading causes of death in the U.S., indicating annual numbers in the hundreds of thousands. John T. James' 2013 estimates point to even higher figures. The wide range in numbers is because diagnosis, reporting methods, and aggregation criteria are not standardized. There is a high possibility of "invisible deaths" that cannot be captured by statistics.

Why medical errors occur: not explained by human error alone

System problems

Medical settings are built on complex systems. Failures in medication management systems, clunky electronic health records, and misleading displays or labeling all contribute to errors. Even with checklists and double-check systems in place, if they are not rigorously implemented their effectiveness is limited. The importance of checklists advocated by Atul Gawande deserves renewed attention in Japanese clinical settings.

Human factors and communication

Long working hours and staffing shortages reduce attention, and inadequate information sharing among doctors, nurses, and pharmacists can lead to misdiagnosis or wrong medications. Also, if there is a culture of "you'll be scolded if you report," problems are less likely to surface and recurrence prevention is hindered. Researchers point out that "responsibility lies with the system, not the individual," and fostering an organizational safety culture is essential.

The situation and challenges in Japan: there is a reporting system, but limits to grasping the reality

Japan has established a reporting system to the Medical Accident Investigation and Support Center, and a certain number of cases are published. However, the current system is self-reporting, and we cannot deny that there are incentives that make it difficult for healthcare workers and facilities to report. The fact that statistical counts are far lower than in the U.S. may be influenced by insufficient reporting and the limitations of diagnostic codes. In the facilities we interviewed, many voices reported feeling the "hurdle of disclosing problems." Ensuring transparency and creating mechanisms focused on improvement rather than blame are needed.

Concrete measures patients and families can take: protect your own life

Here are several safety measures we can practice in daily life. These are methods we ourselves found effective when accompanying family members.
  • Bring a summarized list of symptoms, medical history, allergies, and current medications before your appointment.
  • Always confirm the prescription, the medication name, and the dosage, and if you have questions ask for an explanation on the spot.
  • Before surgery or procedures, ask the doctor to explain the risks, alternatives, and the schedule for the day.
  • If you feel uneasy, don't hesitate to request a second opinion (this is gradually becoming more common in Japan).
  • When hospitalized, ask a family member to play a checking role and confirm any doubts with the nursing staff. Keeping records (notes or photos) is also effective.
  • Make "read-back" at the reception a habit (repeat instructions in your own words to confirm).
These small actions can be the trigger to prevent serious accidents. When we actually tried them, simply asking for explanations often improved communication from the medical side and increased our sense of reassurance.

Summary

Medical errors are not a problem that can be simply blamed on "someone being at fault"; systems and culture are deeply involved. As studies from Johns Hopkins University and John T. James show, the challenges are significant even in the U.S., and in Japan there is a need to improve actual understanding through better transparency and to improve working conditions on the front lines. At the same time, there are practical measures patients and families can take. We, the geefee team, recommend both trusting medical care and actively engaging in your own health. To reduce painful cases, we hope improvements on the medical side and behavioral changes by each citizen will progress together as two wheels of a cart.
