Massachusetts: Avoidable Hospital Errors Continue To Plague Quality Care

Tracking 29 Things That Should Never Happen in a Hospital


Despite a reputation for excellence and innovation, Massachusetts hospitals can sometimes be dangerous places. In an effort improve patient safety, the state Department of Health tracks “serious reportable events” also known as "never events" — avoidable adverse events that should never happen in a hospital.


As defined by Massachusetts law,* a serious reportable event (SRE) is an event that results in a serious adverse patient outcome that is clearly identifiable and measurable, reasonably preventable, and that meets any other criteria established by the department in regulations.
* Section 51H of Chapter 111 of the General Laws

The total number of SREs in Massachusetts acute care hospitals in 2017 was 922. Some of the most common avoidable errors included:

  • Falls = 308
  • Pressure ulcers = 294
  • Surgery on wrong site = 49
  • Medication errors = 52
  • Foreign objects left in patient = 31

** Two events in 2015 and 2016 affected a large number of patients and is reflected in the increase in SREs reported. Data abstracted on Jun 15, 2018 from the Health Care Facility Reporting System.
