Suicide risk screening in primary care is a structured process: a validated screen (often PHQ-9 item 9), a follow-up assessment like the Columbia Protocol (C-SSRS) for anyone who screens positive, then stratified action — safety planning, means-safety counseling, and a warm handoff to behavioral health. It is a workflow, not a single question.

This article explains how that screening workflow is built and run inside a primary care practice. It is operational education for practices and care teams — not individualized medical advice. Anyone with personal concerns should speak directly with their own clinician.

Why screen for suicide risk in primary care?

Primary care is where most people are actually seen. A large share of people who die by suicide have a primary care visit in the weeks or months beforehand — often without mental health ever being the reason for the visit. That makes the primary care office one of the few places where risk can be caught early, in the course of ordinary care, before a crisis.

Screening exists because risk is easy to miss. People rarely volunteer suicidal thoughts unprompted, and a clinician's informal read is not a reliable substitute for a validated question asked consistently of everyone. A defined workflow removes the guesswork about who gets asked and what happens next.

Screening also standardizes care across a busy practice, so the response to a positive result does not depend on which clinician happens to be in the room that day.

How does the screening workflow actually work?

Most practices build the process in stages, so that a brief universal screen feeds a more detailed assessment only when needed.

• Universal or targeted screening. Many practices already administer the PHQ-9 for depression. Item 9 of the PHQ-9 asks about thoughts of being better off dead or of self-harm — which functions as an initial trigger. Some practices use the PHQ-2 first and escalate, or screen specific higher-risk visits.
• A positive screen triggers a structured assessment. Any non-zero response on item 9 (or a direct disclosure) moves the patient to a fuller risk assessment rather than a judgment call in the moment.
• Stratified follow-up. The assessment sorts risk into levels — low, moderate, high — and each level maps to a defined set of actions the team agreed on in advance.
• Documentation and follow-up. The screen, the assessment, the plan, and the next contact are all recorded, so nothing depends on one clinician's memory.

The point of the staged design is consistency: the same trigger produces the same next step every time, regardless of who is in the room.

What is PHQ-9 item 9, and what are its limits?

PHQ-9 item 9 asks how often, over the past two weeks, a patient has had "thoughts that you would be better off dead, or of hurting yourself." It is useful because it is already embedded in depression screening, so it adds no extra instrument.

Its limit is that it is a screen, not an assessment. A positive item 9 signals that a closer look is warranted — it does not, by itself, measure how acute the risk is, whether there is a plan, or what protective factors exist. That is why a positive result should route to a dedicated risk assessment rather than being treated as the whole picture. A "zero" also does not rule risk out on its own, which is why clinical judgment and direct conversation still matter.

What is the Columbia Protocol (C-SSRS)?

The Columbia-Suicide Severity Rating Scale (C-SSRS), sometimes called the Columbia Protocol, is a widely used set of plain-language questions that assess the severity and immediacy of suicidal ideation and behavior. It moves from ideation (wish to be dead, active thoughts) toward more specific and concerning territory (a plan, intent, preparatory behavior, past attempts).

Practices use it because it is validated, brief, and usable by trained non-physician staff — which fits the primary care setting, where a medical assistant or care manager may administer it. The answers stratify risk into actionable tiers, so the team can match the response to the level of concern rather than treating every positive screen the same way.

What happens after a positive screen?

Stratified follow-up means the response scales to the assessed level of risk. The specific thresholds and steps are set by each practice's clinical leadership, but the structure is consistent.

• Imminent or high risk. The patient is not left alone; the team arranges the appropriate level of urgent evaluation, which may include activating emergency services (911) or the 988 Suicide & Crisis Lifeline, per the practice's protocol.
• Moderate risk. The team completes safety planning, addresses means safety, and arranges close, time-bound follow-up with behavioral health — often same-day or next-few-days contact.
• Lower risk. The patient still receives a safety plan and a scheduled follow-up so that the screen leads somewhere, rather than being filed and forgotten.

The recurring principle is that a positive screen is never a dead end. Every tier has a defined next contact.

What is safety planning and means-safety counseling?

Safety planning is a brief, collaborative document the patient and clinician build together: the patient's personal warning signs, coping steps they can take on their own, people and settings that provide distraction or support, who to contact in a crisis (including 988), and how to reach professional help. It is a concrete plan the patient keeps, not a contract promising not to act.

Means-safety counseling (also called lethal-means counseling) is a conversation about putting time and distance between a person at risk and the most dangerous methods — for example, securing or temporarily removing firearms and medications. Because many crises are short-lived, reducing access during the high-risk window is one of the more evidence-supported steps a practice can take.

How does a warm handoff to behavioral health work?

A warm handoff is a direct, in-the-moment introduction — the primary care clinician personally connects the patient to a behavioral health team member, ideally during the same visit, rather than handing over a phone number and hoping the patient calls. Referrals that rely on the patient to follow up on their own are frequently never completed.

In integrated settings such as the Collaborative Care Model (CoCM), a behavioral health care manager is already part of the practice, which makes the handoff faster: the patient meets the person who will coordinate their follow-up before they leave the office. Measurement-based follow-up then tracks whether risk and symptoms are actually improving, and escalates when they are not.

Frequently asked questions

What is the first step in suicide risk screening?

Most practices start with a brief validated screen — commonly PHQ-9 item 9, which is already part of depression screening. Anyone who screens positive moves to a fuller structured assessment such as the C-SSRS. The screen is the trigger, not the conclusion.

Is PHQ-9 item 9 enough on its own?

No. Item 9 flags that a closer look is needed, but it does not measure how acute the risk is or whether there is a plan or intent. A positive result should route to a dedicated assessment and a direct conversation, not stand alone.

What is the C-SSRS used for?

The Columbia-Suicide Severity Rating Scale assesses the severity and immediacy of suicidal thoughts and behavior using plain-language questions. It stratifies risk into levels so a care team can match its response — from routine follow-up to urgent evaluation — to the level of concern.

What should someone do in an immediate crisis?

If you or someone you know is in immediate danger, call or text 988 (the Suicide & Crisis Lifeline), or call 911. The 988 line is free, confidential, and available 24/7.

No. This is educational information about how primary care practices structure suicide risk screening. It is not a substitute for care from a qualified clinician. Anyone with personal concerns should talk directly with their own doctor or a crisis line.
