Complaints, Restraint, and Seclusion in Massachusetts Inpatient Psychiatric Facilities, 2008-2018.

There has been limited research on the quality of inpatient psychiatry, yet policies to expand access have increased, such as the use of Medicaid Section 1115 waivers for treatment in "Institutions for Mental Disease" (IMD). Using data from public records requests, we evaluated complaints, restraint, and seclusion from inpatient psychiatric facilities in Massachusetts occurring from 2008 to 2018, and compared differences in the rates of these events by IMD status. There were 17,962 total complaints, with 48.9% related to safety and 19.9% related to abuse (sexual, physical, verbal), and 92,670 episodes of restraint and seclusion. On average, for every 30 census days in a given facility, restraint, and seclusion occurred 7.47 and 1.81 times, respectively, and a complaint was filed 0.94 times. IMDs had 47.8%, 68.3%, 276.9%, 284.8%, 183.6%, and 236.1% greater rates of restraint, seclusion, overall complaints, substantiated complaints, safety-related complaints, and abuse-related complaints, respectively, compared to non-IMDs. This is the first known study to describe complaints from United States inpatient psychiatric facilities. Policies should strengthen the implementation of patients' rights and patient-centeredness, as well as external critical-incident-reporting systems.
