Self-reported medical errors in seven countries: implications for Canada.

Area of Science:

• Health Services Research
• Patient Safety
• Comparative Health Systems

Background:

• Medical errors pose a significant threat to patient safety globally.
• Understanding the prevalence and risk factors for medical errors is crucial for improving healthcare quality.

Purpose of the Study:

• To determine the rate of self-reported medical errors in Canada compared to six other industrialized nations.
• To identify patient, provider, and system-level risk factors associated with medical errors.

Main Methods:

• Analysis of data from a 2007 Commonwealth Fund survey of 11,910 adults across seven industrialized countries.
• Bivariate analysis and logistic regression were used to compare individuals who reported medical errors with those who did not.

Main Results:

• The rate of self-reported medical errors ranged from 12% to 20% across the seven nations.
• Approximately 16.7% of Canadian adults (4.2 million) reported experiencing a medical error in the past two years.
• Statistically significant risk factors included high prescription drug use, chronic conditions, less physician time, younger age (<65), reduced patient involvement, perceived inadequate nursing staffing, and lack of a regular doctor.

Conclusions:

• Self-reported medical errors are a substantial issue in Canada and other industrialized nations.
• Identifying specific risk factors can inform targeted interventions to enhance patient safety.
• Healthcare decision-makers and clinicians can use these findings to develop strategies for error reduction.
