Congratulations to the Massachusetts Department of Public Health, which this year celebrates its 150th year of existence. DPH released a new logo last week that notes its sesquicentennial. The Massachusetts State Board of Health, now DPH, was established in 1869, with Dr. Henry I. Bowditch as its chairman. While hospitals are some of the most regulated entities, reporting to a variety of agencies in state and federal government, hospitals’ relations to DPH are particularly strong. That relationship is in many cases collaborative. MHA-driven initiatives – such as recent ones combatting substance use disorder or promoting medication for addiction treatment or tobacco cessation, to name just a few – have often been devised and implemented collaboratively between hospitals and DPH. Here’s to future years of collaboration and reasoned regulation.
