In November 2009, CTMC's hospital and homecare services received full accreditation for three years from The Joint Commission.  In January 2008, CTMC's Laboratory Services went through their specific survey with The Joint Commission and also received full accreditation.

The Joint Commission evaluates and accredits more than 15,000 health care organizations and programs in the United States. An independent, not-for-profit organization, the Joint Commission is the nation’s predominant standards-setting and accrediting body in health care. Since 1951, the Joint Commission has maintained state-of-the-art standards that focus on improving the quality and safety of care provided by health care organizations. The Joint Commission’s comprehensive accreditation process evaluates an organization’s compliance with these standards and other accreditation requirements.
