Comprehensive Pain Assessment and Documentation
Key Points
- Effective pain care starts with multidimensional baseline assessment, not score-only screening.
- Subjective data collection is structured with PQRSTU and patient-centered follow-up questions.
- Objective data (vitals, behavior, exam findings) are essential when self-report is limited.
- Documentation and timed reassessment determine whether interventions meet comfort-function goals.
Pathophysiology
Pain is subjective and variably expressed across developmental stages, cognition, culture, and illness context. Because expression may be muted, exaggerated, or nonverbal, nursing assessment must integrate patient report with observable physiologic and behavioral cues.
Inadequate assessment leads to misclassification and ineffective treatment, while thorough baseline data supports targeted intervention selection and safer escalation. Reassessment closes the clinical loop by proving response or treatment failure.
Classification
- Subjective stream: PQRSTU, descriptors, pain history, and comfort-function goal.
- Objective stream: Physical findings, vital trends, behavior/posture/facial cues.
- Scale selection stream: Numeric scale, Wong-Baker FACES, or expanded tools (for example McCaffrey) by patient capability.
- Documentation stream: Baseline, intervention, follow-up, and outcome comparison to goal.
Nursing Assessment
NCLEX Focus
Select the assessment tool the patient can understand; tool mismatch can produce misleading severity ratings.
- Use PQRSTU for consistent subjective baseline: provocation/palliation, quality, region, severity, timing/treatment, understanding.
- Select pain scale by age, cognition, language, and communication ability.
- Assess objective cues including vital signs, guarding, grimacing, mobility limits, and exam abnormalities.
- Assess functional impact (sleep, ADLs, activity, work, social engagement) and define comfort-function goal.
Nursing Interventions
- Document patient-reported pain exactly and clearly identify scale used and context.
- Document objective findings that corroborate or contextualize report.
- Document every pharmacologic and nonpharmacologic intervention with time and rationale.
- Perform and document timely reassessment to determine if comfort-function goal is reached.
Documentation Safety Risk
Delayed or incomplete pain documentation can cause duplicate dosing, undertreatment, and unsafe handoffs.
Pharmacology
Reassessment timing must reflect route and expected onset (for example IV versus oral). Medication-effect documentation should include efficacy and adverse-effect surveillance, not pain score alone.
Clinical Judgment Application
Clinical Scenario
A patient reports 8/10 pain after intervention but appears calmer and has improved mobility.
Recognize Cues: Persistent high score with partial functional improvement. Analyze Cues: Pain burden remains above goal despite some response. Prioritize Hypotheses: Current regimen is insufficient for target function. Generate Solutions: Reassess cause/type, optimize multimodal plan, and escalate if needed. Take Action: Update care plan and document all data streams clearly. Evaluate Outcomes: Trend toward patient-defined comfort-function goal.
