Alcohol, Drug, and Addiction Partial Hospital Program

Intensive Day Treatment for Addiction to Drugs or Alcohol

The Alcohol, Drug, and Addiction Partial Hospital Program provides treatment for individuals with substance use disorders, including the misuse of alcohol, prescription drugs, heroin, cocaine, marijuana, or opioids such as Oxycontin or Percocet.

A partial hospital (day) program is an intensive, therapeutic environment for patients who do not require 24-hour care yet need more structure than is available in outpatient treatment. The program is designed for patients who are able to successfully manage their symptoms while at home or in a residential care setting.

Our expert staff specialize in treating individuals whose substance use disorder is complicated by other psychiatric illnesses such as depression, anxiety, bipolar disorder, and post-traumatic stress disorder.

For more information or to make a referral, please call 617.855.3505.

This day treatment program is ideal for those who:

  • Seek intensive addiction care for substance use disorders, with or without any other mental health symptoms
  • Require more structure than is available in traditional outpatient care and are able to successfully manage their symptoms while at home or in a residential care setting

The program runs Monday through Friday from 8:30am to 2pm. Through educational and process-oriented group therapy sessions, we assist patients through the early stages of addiction recovery. Treatment takes place over 10 to 14 days and is covered by most insurance providers.

According to the National Council on Alcoholism and Drug Dependence, 17.6 million Americans, or 1 in every 12 adults, struggle with alcohol misuse or dependence.

The emphasis of the day program, reinforced by scientifically proven treatments and cutting-edge therapy models, is to provide a sufficient level of stability for the patient to be able to gradually leave treatment.

Treatment Approach

Our expert staff work in close partnership with patients and families to focus on creating a customized treatment plan for each individual based on his or her substance use history and symptoms, the severity of the symptoms, and other co-occurring psychiatric diagnoses.

Treatment plans include a combination of individual and group therapies, a variety of proven addiction treatment models, and medications that help patients manage their symptoms and transition back to their daily lives.

Upon admission, we create a tailored treatment plan for each patient targeted at reducing the severity of the patient’s symptoms. We provide tools, ongoing support, and resources to prevent relapse.
