Substance use disorder is a serious condition that affects how people think, feel, and behave. It often causes problems with health, relationships, and daily life. Treating it requires care that fits the person’s specific needs.
To guide this process, the American Society of Addiction Medicine (ASAM) created a system called the continuum of care. Understanding this system can help individuals and families choose the right level of care at the right time.
This article will explain what a level of care means, outline ASAM’s official levels, from early help to full medical care, and show how people move through these levels during treatment.
What Does a Level of Care Involve In Addiction Treatment
A level of care refers to the intensity and structure of treatment a person receives based on their needs. It includes how often treatment occurs, the type of setting, and the level of medical or clinical support provided.
Treatment providers use clinical assessments to determine the most appropriate level of treatment. These evaluations consider substance use history, mental health, withdrawal risk, home environment, and motivation for change. The goal is to match the person with care that fits their condition—whether that’s outpatient treatment, residential care, or inpatient services.
The more severe the substance use disorder, the higher the level of care required. Someone early in their use may benefit from an outpatient program, while someone with repeated relapse or co-occurring issues may need 24-hour care in a structured setting. Understanding these levels helps individuals and families find the right starting point for recovery.
Level 0.5: Early Intervention Services
This level targets individuals who are at risk of developing a substance use disorder but do not yet meet the diagnostic criteria. The focus is on prevention, education, and brief intervention strategies. Services are often delivered in schools, primary care settings, or through community outreach. Early intervention is especially important in reducing progression toward more severe substance abuse.
Level 1: Outpatient Services
Level 1 represents the lowest structured care in the continuum. Clients typically attend therapy fewer than 9 hours per week, allowing them to maintain work, school, and family responsibilities. This outpatient level of care is ideal for individuals with mild symptoms, high motivation for recovery, and a stable home environment. It may include group therapy, individual counseling, education on substance use, and relapse prevention planning. As a treatment option, it provides support without requiring clients to leave their day-to-day lives.
Level 2: Intensive Outpatient and Partial Hospitalization Services
At Level 2, care becomes more intensive and structured.
- Level 2.1 Intensive Outpatient Program (IOP): Clients participate in at least 9 hours of therapy per week. These intensive outpatient programs offer a balance of flexibility and accountability, often serving as a step-up from Level 1 or a step-down from residential care.
- Level 2.5 Partial Hospitalization Program (PHP): Also known as day treatment, PHPs typically provide 20 or more hours of care per week. Patients attend full-day sessions, often involving medical monitoring, psychiatric evaluation, and structured therapeutic activities.
Both IOP and PHP serve individuals who need more than basic outpatient treatment but do not require full inpatient treatment. These services are particularly useful for those with co-occurring conditions or unstable living situations who can still benefit from living at home.
Level 3: Residential/Inpatient Services
Level 3 encompasses several types of residential treatment, offering 24-hour structured care in a non-hospital setting:
- Level 3.1: Clinically Managed Low-Intensity Residential Services focus on peer support and recovery-oriented services.
- Level 3.3: Population-Specific High-Intensity Services serve individuals with cognitive impairments or chronic relapse histories.
- Level 3.5: Clinically Managed High-Intensity Residential Services provide full-time care for those with significant functional impairment due to substance use.
- Level 3.7: Medically Monitored Intensive Inpatient Services add nursing oversight and medical monitoring, making them appropriate for individuals with health complications but who don’t require hospital-level care.
These settings deliver a range of treatment services, including behavioral therapy, case management, medication support, and group sessions. This type of treatment is well-suited for individuals with severe substance use disorder who lack the stability or support to recover in an outpatient environment.
Level 4: Medically Managed Intensive Inpatient Services
Level 4 is the most intensive level in ASAM’s framework and is typically delivered in hospital-based treatment facilities. It provides 24-hour nursing care with physician oversight, making it suitable for individuals undergoing medically complicated withdrawal, suffering from acute psychiatric symptoms, or experiencing a crisis due to substance abuse and mental health issues.
Detox is a key component of this level, where individuals are safely monitored during withdrawal to prevent life-threatening complications. These treatment programs are designed for stabilization and transition into a lower level of care once medical and psychiatric needs are managed. This highest level of care is critical for safety and survival in acute stages and is usually time-limited. Once stabilized, individuals often move into Level 3.7 or Level 2.5 as part of the treatment process.
Finding the Right Level of Care and Transitioning Through the Continuum
Selecting the right treatment level is not a matter of guesswork. A clinical assessment based on ASAM criteria helps determine which type of care best suits the individual’s needs. Throughout the continuum of care, patients may transition from one level to another depending on how their symptoms evolve, their response to treatment, or the stability of their environment.
For instance, someone who begins with inpatient treatment may transition to residential care, followed by an intensive outpatient program, and eventually step down to outpatient services. These transitions reflect a flexible continuum of several levels, ensuring the patient receives the care they need at each stage of recovery. This ability to adapt is why the ASAM levels of care are considered the foundation for successful long-term recovery.
