Screening, SBIRT & the ASAM Criteria Levels of Care
Key Takeaways
- Screen, assess and diagnose is the single largest CARN-AP activity area at 30% of items, or roughly 44 to 46 of 150 questions.
- SBIRT separates universal screening from brief intervention (5 to 15 minutes, motivational) and referral to treatment, and is designed for general medical settings rather than addiction specialty care.
- The ASAM Criteria assess six dimensions and place patients across five broad levels of care from Level 0.5 early intervention to Level 4 medically managed intensive inpatient.
- Dimension 1 (acute intoxication/withdrawal potential) and Dimension 3 (emotional, behavioral or cognitive conditions) most often drive an increase in level of care.
- A level-of-care recommendation must reflect the patient's actual dimensional needs, not bed availability, insurance preference, or the patient's request — documenting the mismatch is the APRN's obligation when the recommended level is unavailable.
Screening, SBIRT & the ASAM Criteria Levels of Care
Quick Answer: SBIRT — Screening, Brief Intervention, and Referral to Treatment — is the public-health model for detecting unhealthy substance use in general medical settings. Screening uses brief validated instruments (AUDIT-C, single-item alcohol or drug screen, DAST-10, TAPS, CRAFFT for adolescents); brief intervention is a 5- to 15-minute motivational conversation; referral to treatment is reserved for patients meeting criteria for a substance use disorder. The ASAM Criteria then match a patient to a level of care using six assessment dimensions, producing placements from Level 0.5 (early intervention) through Level 4 (medically managed intensive inpatient).
1. Why This Section Carries the Most Weight
Activity Area I — screen, assess and diagnose the processes and complications of substance-related and addictive disorders — is 30% of the CARN-AP, about 44 to 46 items. The highest-rated activity within it is “utilizes complex data and information obtained during interviews, examinations, and diagnostic processes when identifying diagnoses” (mean index 10.67). Exam items in this area rarely ask you to recall a cutoff in isolation; they give you interview data, physical findings and labs, then ask what the data mean together.
2. Screening Instruments Worth Knowing Cold
| Instrument | Target | Length | Common threshold |
|---|---|---|---|
| AUDIT | Alcohol use, past year | 10 items | 8 or more suggests hazardous use; 20 or more suggests likely dependence |
| AUDIT-C | Alcohol consumption only | 3 items | 4 or more in men, 3 or more in women |
| Single-Item Alcohol Screen | Heavy drinking days | 1 item | Any report of 5 or more drinks (men) or 4 or more (women) in a day in the past year |
| CAGE | Lifetime alcohol problems | 4 items | 2 or more; poor sensitivity for current hazardous drinking |
| DAST-10 | Drug use, past year | 10 items | 3 or more suggests moderate problems |
| TAPS Tool | Tobacco, alcohol, prescription and other substances | 4-item screen plus brief assessment | Any positive triggers the substance-specific module |
| CRAFFT | Adolescents, all substances | 6 items | 2 or more warrants full assessment |
| NIDA Quick Screen / ASSIST | All substances, risk tiers | Variable | ASSIST specific substance involvement score guides intervention level |
Exam trap: CAGE asks about lifetime problems and is insensitive to current hazardous drinking, particularly in women and older adults. When a stem describes a patient with recent heavy drinking but no history of guilt or eye-openers, a negative CAGE does not rule out an alcohol use disorder — AUDIT-C or a single-item heavy-drinking-day question is the better screen.
3. SBIRT in Practice
- Screening. Universal, not targeted. Applying screening only to patients who “look like” they use substances reproduces bias and misses the majority of unhealthy use, which occurs in employed, insured, socially stable people.
- Brief Intervention. A structured 5- to 15-minute motivational conversation. The FRAMES elements — Feedback, Responsibility, Advice, Menu of options, Empathy, Self-efficacy — remain the most testable summary. Brief intervention has its strongest evidence for unhealthy alcohol use that does not meet criteria for a disorder; it is not a substitute for treatment of moderate-to-severe substance use disorder.
- Referral to Treatment. Indicated when the assessment supports a diagnosis requiring specialty care. A warm handoff — direct introduction to the receiving clinician while the patient is still present — substantially outperforms a phone number on discharge paperwork.
A high-yield nuance: brief intervention alone has repeatedly failed to change outcomes for drug use (as distinct from alcohol) in primary care trials. On the exam, a patient with a moderate or severe opioid or stimulant use disorder needs treatment engagement and, where indicated, medication — not a brief intervention.
4. The Six ASAM Dimensions
| Dimension | What it assesses | Example of what raises level of care |
|---|---|---|
| 1. Acute intoxication and/or withdrawal potential | Current intoxication, withdrawal risk, prior severe withdrawal | History of withdrawal seizures or delirium tremens |
| 2. Biomedical conditions and complications | Physical health problems needing concurrent care | Untreated endocarditis, poorly controlled diabetes, advanced pregnancy |
| 3. Emotional, behavioral or cognitive conditions and complications | Psychiatric symptoms, suicidality, cognitive impairment | Active suicidal ideation with plan; acute psychosis |
| 4. Readiness to change | Motivation, engagement, awareness | Externally coerced with no internal motivation |
| 5. Relapse, continued use or continued problem potential | Craving severity, relapse history, coping skills | Repeated relapse within days of leaving lower levels |
| 6. Recovery/living environment | Housing, safety, support, transportation | Unhoused; living with an actively using partner; domestic violence |
5. Levels of Care
| Level | Setting | Typical intensity |
|---|---|---|
| 0.5 | Early intervention | Education and brief intervention for at-risk use without a diagnosis |
| 1 | Outpatient | Fewer than 9 hours per week of structured services for adults |
| 2.1 | Intensive outpatient | 9 or more hours per week for adults |
| 2.5 | Partial hospitalization | 20 or more hours per week with daily clinical access |
| 3 (3.1–3.7) | Residential/inpatient | From clinically managed low-intensity residential through medically monitored intensive inpatient |
| 4 | Medically managed intensive inpatient | 24-hour nursing with physician availability; acute hospital level |
Withdrawal management runs on a parallel track across these levels — ambulatory withdrawal management with or without extended on-site monitoring, clinically managed residential withdrawal management, and medically monitored or medically managed inpatient withdrawal management.
6. Making — and Defending — a Placement Decision
Three rules that recur as exam answers:
- The highest-acuity dimension drives the placement. A patient who is medically stable, motivated and housed but has a documented history of withdrawal seizures is placed on Dimension 1 severity, not on the average of the six dimensions.
- Placement follows assessment, not availability. When the indicated level of care is unavailable, the APRN documents the recommended level, the reason it could not be provided, the interim plan, and the specific conditions that should trigger escalation. Writing a lower level of care into the record because a bed is unavailable misrepresents the assessment.
- Readiness to change modifies the plan, not the diagnosis. Low readiness (Dimension 4) calls for motivational strategies and often a more supportive level of care — it is never grounds for discharging a patient as “not ready for treatment.”
A 62-year-old woman drinks four glasses of wine most evenings. She denies guilt about drinking, has never felt she should cut down, has never been annoyed by criticism, and has never needed a morning drink. Her CAGE score is 0. What is the most appropriate APRN interpretation?
An APRN completes an ASAM Criteria assessment on a patient who is medically stable, housed with a supportive family, highly motivated, and has moderate craving, but who has twice experienced withdrawal seizures during prior alcohol cessation. Which dimension should drive the level-of-care recommendation?
A hospital's addiction consult service cannot obtain a residential bed for a patient whose ASAM assessment supports Level 3.7 withdrawal management. The utilization reviewer asks the APRN to document Level 2.1 instead so the discharge is not delayed. What is the correct action?
