What does “Joint Commission” mean?
Short answer
The Joint Commission is a US group that accredits hospitals, outpatient, nursing care and home care sites. It also sets the Sentinel Event Policy.
Also known as: TJC, The Joint Commission
What it is
It publishes a Comprehensive Accreditation Manual for each type of site, such as hospitals, nursing care centers, home care and assisted living. Each manual has a chapter on the Sentinel Event Policy, first adopted in 1996.
Its Office of Quality and Patient Safety (OQPS) reviews reported sentinel events, plus the analysis and action plan a site sends in.
After a serious event
Sites it accredits need a sentinel event policy. They must study each such event in full, most often with a root cause analysis. Then they carry out the action plan and check that it works.
Reporting to the Joint Commission is encouraged, not required. Surveyors check how a site responds to safety events, adverse events, unsafe conditions and close calls, and to sentinel events. They do not hunt for them.
Mix-up: its standards are not CMS rules. Its accreditation can support deemed status where CMS has approved its program, but the site still follows CMS rules. Its terms, like sentinel event, also differ from CMS usage.
Frequently asked questions
Is Joint Commission accreditation mandatory?
Not for Medicare. It is voluntary, and providers can use State agency surveys instead. Some states, payers or contracts may require it.
Does the Joint Commission require reporting of sentinel events?
No. Self-reporting is strongly encouraged, not required. You must still have a policy and study every such event in full.
Does a sentinel event affect our accreditation decision?
Not by itself, says the policy. Willful failure to respond well could, such as missing the extra 45 days after the analysis is due.
