[Medical errors or deviations in daily health care practice]

Area of Science:

• Medical error analysis
• Healthcare quality improvement
• Patient safety research

Background:

• Increasing concern regarding adverse events in medical literature since 1991.
• Institute of Medicine (IOM) report in 1998 prompted national action on healthcare quality.
• Adverse events are linked to deviations in hospital stays and mortality rates, with a significant portion being preventable.

Purpose of the Study:

• To analyze the underlying reasons for adverse events in healthcare.
• To emphasize the importance of prevention over legal punishment.
• To advocate for a cultural shift towards collaboration and improved healthcare quality.

Main Methods:

• Analysis of deviations in hospital stay and mortality rates.
• Examination of contributing factors to adverse events, distinguishing between human error and systemic issues.
• Review of cognitive psychology principles related to human performance and decision-making.
• Exploration of industrial safety models, such as those in civil aviation, for adaptation to healthcare.

Main Results:

• Deviations in hospital stay range from 3.7% to 45.8%, with mortality rates between 4.9% and 5.6%.
• A significant percentage (51%-54%) of these events are avoidable, with only 27% attributed to negligence.
• Adverse events often result from a combination of occasional and underlying factors, not solely isolated human error.

Conclusions:

• Preventing adverse events requires understanding their complex causes and implementing systemic changes.
• A cultural transformation is needed, moving from a defensive stance to one of open collaboration and reporting.
• Adopting industry best practices for safety and ensuring confidentiality are crucial for fostering an environment that prioritizes patient safety and quality of care.
