Quick answer: A patient assessment is the structured way a clinician gathers information about a patient’s health, makes sense of it and decides what care comes next. It combines what the patient reports (subjective data) with what the clinician measures and observes (objective data): the health history, vital signs, a physical exam and validated screening tools.

It isn’t a one-time event. A good assessment is repeated, so the care team can see whether the patient is getting better or worse.

Every care decision starts with an assessment. A nurse checking a new admission, a paramedic at a car crash and a care manager calling a heart failure patient at home are all assessing a patient, just at different depths and for different reasons.

This guide explains what a patient assessment is, the main types, how to assess a patient step by step, and the validated tools clinicians use, with a filled-in sample. It also covers the part most guides skip: the assessments Medicare requires before a practice can run care management programs like CCM and the Annual Wellness Visit.

What Is a Patient Assessment?

A patient assessment is the first step of the nursing process, often taught as ADPIE: assessment, diagnosis, planning, implementation and evaluation. Physicians, nurse practitioners, physician assistants, nurses, pharmacists and care managers all do some version of it.

Every assessment collects two kinds of information.

Subjective dataObjective data
What it isWhat the patient (or a caregiver) tells youWhat you can measure, see, hear or test
Examples“I get short of breath climbing stairs.” Pain rated 6 out of 10. Feeling down most days.Blood pressure 152/94. Weight up 2.3 kg in a week. Ankle swelling. A PHQ-9 score of 12.
How you get itInterview, questionnaires, patient-reported outcomesVital signs, physical exam, labs, device readings

Neither one is enough alone. A patient can feel fine with a dangerously high blood pressure, and a normal set of vitals can hide a patient who has quietly stopped taking their medication.

Types of Patient Assessments

TypeWhen it’s doneWhat it covers
Comprehensive (initial)A new patient, a hospital admission, or the start of a care management programFull health history, review of systems, head-to-toe exam, function, psychosocial needs
FocusedA specific problem or complaintOne body system or concern, such as chest pain or a wound
Ongoing (reassessment)At set intervals, or after any change or treatmentWhether the patient is improving, stable or getting worse
Emergency (primary survey)An unstable or critically ill patientImmediate threats to life, using the ABCDE approach
Functional and geriatricOlder adults, before discharge, or when independence is in questionDaily activities, mobility, fall risk, cognition
Psychosocial and behavioralRoutine screening, or when mood or substance use is a concernDepression, anxiety, alcohol use, social needs
Risk assessmentOn admission and regularly afterwardRisk of falls, pressure injuries, readmission or malnutrition

How to Assess a Patient, Step by Step

The order changes with the setting, but a thorough assessment usually follows these steps.

1. Check for anything urgent first

If the patient looks unwell, start with a primary survey before anything else. The ABCDE approach, taught by bodies such as the Resuscitation Council UK, checks Airway, Breathing, Circulation, Disability (level of consciousness) and Exposure, fixing each problem before moving on. A stable patient can skip straight to the history.

2. Review what you already know

Read the chart, recent results, the medication list and notes from other clinicians. It saves the patient from repeating their story and shows you what changed since the last contact.

3. Take the health history

Start with the main concern in the patient’s own words. Then cover the history of the present illness, past medical and surgical history, medications and allergies, family history and social history (smoking, alcohol, living situation, support at home). For a symptom, the OLDCARTS prompt keeps you thorough: onset, location, duration, character, aggravating factors, relieving factors, timing and severity.

4. Measure vital signs

Temperature, pulse, respiratory rate, blood pressure and oxygen saturation, plus pain and weight where relevant. A single reading tells you less than a trend, which is why repeated measurements matter so much in chronic disease.

5. Do the physical exam

Use the four classic techniques: inspection, palpation, percussion and auscultation. A head-to-toe exam suits a comprehensive assessment. A focused exam suits a single complaint.

6. Use validated screening tools

Standard tools turn a vague impression (“she seems a bit down”) into a number you can track and compare. The examples below are the ones most often used in primary care and care management.

7. Analyze, document and act

Pull the findings together, decide what they mean, and write them up in a format others can follow. SOAP (subjective, objective, assessment, plan) is the most widely used. Then act on it, and set a time to reassess.

Patient Assessment Examples: 9 Validated Tools

ToolWhat it assessesHow it’s scored
PHQ-9Depression0–27. Scores of 5, 10, 15 and 20 mark mild, moderate, moderately severe and severe depression.
GAD-7Anxiety0–21. Scores of 5, 10 and 15 mark mild, moderate and severe anxiety. 10 or more usually prompts further evaluation.
Mini-CogCognitive impairment0–5, from a three-word recall and a clock drawing. A score of 0–2 is a positive screen.
Timed Up and Go (TUG)Fall risk and mobilityThe patient stands up, walks 3 meters, turns, walks back and sits. CDC’s STEADI program treats 12 seconds or more as a sign of fall risk.
Katz ADL IndexBasic daily activitiesSix items (bathing, dressing, toileting, transferring, continence, feeding), one point each. 6 means fully independent.
Lawton IADL ScaleIndependent living skillsEight items, including phone use, shopping, cooking, housekeeping, laundry, transport, medications and finances.
AUDIT-CAlcohol useThree questions, 0–12. A 2007 review recommended 4 or more for men and 3 or more for women as a positive screen.
Braden ScalePressure injury risk6–23, across six areas such as mobility, moisture and nutrition. Lower scores mean higher risk.
Numeric pain rating scalePain intensityThe patient rates pain from 0 (none) to 10 (worst imaginable).

A screening tool flags a possible problem. It doesn’t diagnose one. A high PHQ-9 score, for example, calls for a clinical interview, not an automatic depression diagnosis.

Sample Patient Assessment (SOAP Format)

Here’s what a monthly care management assessment can look like, written up in SOAP format. The patient is invented. The structure is the part to copy.

Patient: 74-year-old woman with heart failure and type 2 diabetes, enrolled in chronic care management. Monthly telephone assessment.

S (subjective): Reports more breathlessness on stairs this week and needs two pillows at night, up from one. Has missed her evening diuretic “a few times” because it keeps her up at night. Mood “okay”. Denies chest pain.

O (objective): Home monitoring readings: weight up 2.1 kg over 5 days, blood pressure 148/88, heart rate 92, SpO2 94%. Fasting glucose averaging 168 mg/dL. PHQ-9 today: 6.

A (assessment): Signs of fluid retention, likely linked to missed diuretic doses. Glucose above goal. Mild depressive symptoms, stable from last month.

P (plan): Same-day message to her cardiologist about the weight gain. Discussed taking the diuretic earlier in the day; pharmacist review of timing requested. Daily weights to continue, with a call back if weight rises another 1 kg. Repeat PHQ-9 next month. Reassess in 3 days.

Notice how the remote readings carry the objective section. With a remote patient monitoring program, a phone assessment gets real numbers instead of only the patient’s memory.

The Patient Assessments Medicare Requires

For practices, assessments aren’t only good care. Several Medicare services require them before you can bill.

Annual Wellness Visit: the health risk assessment

The Annual Wellness Visit starts with a health risk assessment. According to CMS’s AWV page (updated April 9, 2026), it should collect at minimum:

  • Demographic data
  • A self-assessment of health status
  • Psychosocial risks, such as depression, stress, loneliness and pain
  • Behavioral risks, such as tobacco use, physical activity, diet and alcohol
  • Activities of daily living (ADLs) and instrumental activities of daily living (IADLs)

The visit also checks for cognitive impairment, reviews depression risk and looks at functional ability and safety, including fall risk and hearing.

Chronic care management: the comprehensive assessment

Before chronic care management can start, CMS requires an initiating visit (an E/M visit, AWV or IPPE) for new patients or anyone not seen in the past year. The care plan must then be built on what CMS’s MLN909188 booklet (June 2025) calls “a physical, mental, cognitive, psychosocial, functional, and environmental assessment and an inventory of resources and supports.”

That’s a comprehensive assessment in all but name, and it has to be revisited as the plan is monitored and revised. Principal care management works the same way for a single high-risk condition, with a disease-specific care plan. Our guide to what PCM means in medical terms covers the difference.

Behavioral health integration: validated scales

Behavioral health integration depends on repeated, validated measurement, which is why tools like the PHQ-9 and GAD-7 show up in almost every program. The score at enrollment and the score each month show whether treatment is working.

We see the same pattern in the practices we work with. The ones that run care management well don’t treat the assessment as paperwork. They use the same tools every month, so a change in score or weight stands out quickly.

Common Patient Assessment Mistakes

  • Assessing once and never again. A baseline is only useful if you compare against it.
  • Leaning on one source. Patients under-report symptoms, and single readings mislead. Combine the interview, the numbers and the tools.
  • Skipping the caregiver. For older or cognitively impaired patients, the person at home often knows the most.
  • Vague documentation. “Patient doing okay” tells the next clinician nothing. Record numbers, scores and the patient’s own words.
  • Screening without a plan. Every tool needs a next step for a positive result, decided before you start using it.

Patient Assessment: Frequently Asked Questions

What is a patient assessment?

A patient assessment is the structured process of collecting subjective information (what the patient reports) and objective information (vital signs, exam findings, test results and screening scores), interpreting it and using it to plan care. It’s the first step of the nursing process and is repeated over time.

What are the main types of patient assessments?

The main types are comprehensive (initial), focused, ongoing (reassessment) and emergency assessments, along with specialized functional, psychosocial and risk assessments such as fall risk or depression screening.

What are the steps to assess a patient?

Check for urgent problems first with the ABCDE approach, review the chart, take the health history, measure vital signs, do the physical exam, use validated screening tools, then analyze, document (often in SOAP format), act and reassess.

What is an example of a patient assessment?

A common example is a PHQ-9 depression screen, a Timed Up and Go test for fall risk, or a monthly care management call where the clinician reviews symptoms, home blood pressure and weight readings, and medication adherence, then updates the care plan.

What is the difference between subjective and objective data?

Subjective data is what the patient says, such as symptoms, pain level or how they feel. Objective data is what a clinician can measure or observe, such as blood pressure, weight, exam findings or a test score.

What is a health risk assessment in Medicare?

It’s the questionnaire that opens the Medicare Annual Wellness Visit. It collects demographic data, a self-assessment of health, psychosocial and behavioral risks, and the patient’s ability to manage daily activities, and it’s updated at each yearly visit.

How often should a patient be reassessed?

It depends on the setting. Hospitals reassess every shift or after any change. In chronic care management, patients are typically reassessed monthly, with extra contact whenever symptoms, readings or medications change.
