Path to Recovery

Catholic Health offers services and programs across Long Island to help with substance abuse problems. Our experts are skilled at all aspects of detoxification, rehabilitation and recovery. We create a treatment plan that fits your unique situation and needs. Because recovery is ongoing, we also provide tools to help you maintain a substance-free life.

Inpatient Services

When going through detoxification, some individuals may have severe withdrawal problems that require inpatient medical services. St. Charles Hospital (Port Jefferson, NY) offers medically supervised detox to help reduce the physiological and psychological risks for ages 12 and older.

How the process works:

  • A physician or another medical professional uses evidence-based screening tools to determine admission.
  • The patient enters our acute care setting for 24-hour medically directed evaluation and treatment.
  • Physicians and nurses provide specialized care and observation.
  • Physicians and nurses administer medication according to physical needs, while helping to maintain a manageable level of comfort.

St. Charles Hospital has up to 20 hospital beds dedicated to medically supervised detoxification. As a licensed acute care hospital, we can manage complex medical conditions. The adult program is for those aged 18 and older. The adolescent program is for teens aged 12 to 18.

Detoxification is the first step in recovery. Requesting a referral to an inpatient or outpatient program at St. Charles Hospital is recommended.

St. Charles Hospital (Port Jefferson, NY) offers drug and alcohol rehabilitation for ages 18 and older. Our voluntary chemical dependency rehabilitation program is designed to promote recovery. The goal of treatment is to reduce the risk of relapse while helping you live without drugs and alcohol.

Approaches we use include:

  • 12-step principles
  • Affect regulation—skills to help you regulate your emotions
  • Cognitive restructuring—techniques to identify and change negative thinking
  • Relapse prevention training
  • Wellness concepts

Services include:

  • Continuum of care
  • Group therapy
  • Individual assessment
  • Individual therapy
  • Medical supervision
  • Support groups
  • Urine screens and breathalyzer tests
  • Workshops and homework assignments

Medication-assisted treatment, which uses FDA-approved medications in combination with behavioral therapies, is another method to help treat substance abuse.

Treatment also addresses other concerns, such as emotional and behavioral health issues, coexisting psychiatric disorders, and family, work and community concerns. After completing the program, you'll receive information about support services to help with ongoing recovery.
