Comparison Tables for Making Healthcare Safer Reports
The tables below compare all editions of the Agency for Healthcare Research and Quality’s Making Health Care Safer report.
The first edition, published in 2001, was developed following the 1999 publication of To Err is Human: Building a Safer Health System, the seminal National Academy of Medicine report that elevated awareness of longstanding risks and patient harms occurring in the U.S. healthcare system. The inaugural report consisted of 50 patient safety practices in eight categories encompassing commonly occurring care and disease specific adverse events and associated systemic and contextual factors.
In 2013, AHRQ published a second edition of Making Health Care Safer. That report added new evidence-based safety practices while updating some practices with new evidence, and contained a total of 41 patient safety practices.
AHRQ’s third Making Healthcare Safer report, published in 2020, includes 47 evidence-based patient safety practices in selected harm areas. It includes evidence for more specific harm areas than the preceding reports.
The fourth Making Healthcare Safer report was commissioned in 2022 as a continuous updating of patient safety harms and practices. To address the emerging and evolving threats to patient safety, the advances in patient safety research, and the evolving accrediting body standards, this format intends to provide the most updated evidence-based information to aid healthcare organization leaders in facilitating adoption and implementation in a timelier way.
Taken together, the reports cover a wide range of patient safety practices. Methodologically, the practices (or PSPs) are similar but not identical. Following the first report, PSPs were included in subsequent reports if there was evidence for a new practice for improving patient safety or the topic was considered a pressing issue at the time of the report development. Subsequent reports also updated some PSPs of the previous report because there was new evidence available for the PSP or the topic was still considered a pressing issue for patient safety. Other PSPs were not updated because either there was no new evidence available or the topic was not considered a priority issue when the report was developed. For these reasons, a summary of evidence is not available for many PSPs. The cells indicating “(Not reviewed)” reflect that the topic was not reviewed and a summary of evidence is not available.
Although the methodology and context of collection of the patient safety practices of these three reports may vary, they serve as a consolidated source of evidence-based information for healthcare providers, health system administrators, researchers, and government agencies to use in patient safety improvement efforts.
