Which option best describes the essential elements of a comprehensive substance use assessment in primary care?

• A. Substance-use history, withdrawal risk, readiness to change, comorbid medical/psychiatric conditions, psychosocial factors, screening results, overdose risk, and a clear treatment referral plan
• B. Withdrawal risk, readiness to change, and comorbid conditions only
• C. Screening results and overdose risk only
• D. Substance-use history, psychosocial factors, withdrawal risk, readiness to change, comorbid conditions, screening results, overdose risk, and a clear treatment referral plan

Answer: (D)

A comprehensive substance use assessment in primary care should cover multiple interacting domains to guide safe, effective care. This includes gathering the substance-use history to understand patterns and risks, evaluating psychosocial factors such as support, housing, and employment, assessing withdrawal risk to anticipate physical symptoms and safety with cessation, and gauging readiness to change to tailor motivational approaches. It also requires identifying comorbid medical or psychiatric conditions that can influence treatment choices and safety, reviewing screening results to quantify risk and determine next steps, assessing overdose risk to address safety urgently, and establishing a clear treatment referral plan to connect the patient with appropriate care or resources. Together, these elements provide a complete picture that supports a patient-centered management plan.

Options that omit any of these domains would miss important pieces of the overall assessment—for example, focusing only on withdrawal risk and readiness to change ignores history, psychosocial context, and the plan for treatment, while focusing only on screening results and overdose risk misses the broader clinical picture and necessary follow-through.
