Abstract:
:The Institute of Medicine (IOM) report, To err is human, galvanized a dramatically increased level of concern about adverse events and patient safety in healthcare, including errors in laboratory medicine. While a significant decrease in the error rates of clinical laboratories has been achieved and documented in recent decades, available evidence demonstrates that the pre- and post-analytical phases of the total testing process are more vulnerable to errors than the analytical phase. However, analytical quality is still a major issue, particularly in some areas of laboratory medicine such as immunoassaying. In the present paper, current trends and factors that could effect future changes in the frequency and types of errors in laboratory services are analyzed and discussed. A more effective integration of automation and information technology could allow clinical laboratories to identify, control and decrease error rates in the total testing process, but interdepartmental cooperation and communication with clinicians and other stakeholders are essential to improving patient safety. Moreover, a fundamental shift in improving patient safety in laboratory medicine is to move from error reporting to risk management.
