🔹 Sources of Pain

Pain can be categorized based on its origin:

• Visceral pain → from larger internal organs (injury, distention, ischemia). Often accompanied by autonomic responses such as nausea, vomiting, pallor, diaphoresis. Poorly localized due to sparse innervation of visceral structures. Described as dull, crampy, or aching.
• Deep somatic pain → from blood vessels, joints, tendons, muscles, bones. Described as aching or throbbing; usually well localized; may include systemic signs (nausea, tachycardia, hypertension). Somatic = Structures for movement.
• Cutaneous pain → from skin and subcutaneous tissues. Superficial, sharp, burning sensation.
• Referred pain → felt at a site distant from the origin. Occurs because both sites are innervated by the same spinal nerve, making it difficult for the brain to localize the true source.

⚡ Types of Pain – Classification

Pain can be classified based on its duration. This distinction is important because it provides insight into underlying mechanisms and guides treatment decisions.

📌 Quick Summary

• Acute pain → short-term, protective, predictable, resolves with healing.
• Incident pain → predictable acute pain with movement/activity.
• Chronic pain → lasts ≥6 months, persists beyond healing, malignant (tumor-related) or nonmalignant (arthritis, back pain, fibromyalgia).
• Breakthrough pain → spike acute pain in patients with “controlled“ chronic pain.

📖 Developmental Competence in Pain Assessment

👵 The Aging Adult

There is no evidence that older adults perceive pain less intensely or have diminished sensitivity. Pain is a common experience in those over 65.

→ It should never be considered a normal part of aging. Pain in older adults always indicates pathology or injury and should not be tolerated or dismissed. Unfortunately, both clinicians and older patients often assume that pain is expected in later years, which leads to undertreatment.

Older adults also face unique fears related to pain management, including worries about becoming dependent, undergoing invasive procedures, needing long-term pain medication, and creating a financial burden.

Most common causes of pain in older adults: arthritis, osteoarthritis, osteoporosis, peripheral vascular disease, cancer, neuropathies, angina, and chronic constipation.

Dementia:

It is important to note that dementia does not reduce the ability to feel pain, but it does affect the ability to effectively use self-report tools, making assessment more challenging.

🚹🚺 Gender Differences

Gender influences pain perception through societal expectations, hormonal changes, and genetics. Traditionally, men have been encouraged to be stoic, while women’s emotional expressions of pain are more accepted.

Hormonal changes strongly affect women’s pain sensitivity. Women are:

• 2–3 times more likely to experience migraines during childbearing years
• More sensitive to pain during the premenstrual period
• 6 times more likely to have fibromyalgia

🌍 Cultural Differences in Pain

Silent pain: refers to the experience of physical or emotional suffering that is not openly expressed, leading to internalized struggles and often hidden from others

Culture greatly shapes the expression and reporting of pain. Patients from different backgrounds may under-express pain or show pain in ways unfamiliar to the provider.

• Always use interpreters when language barriers exist to avoid misunderstanding.
• Lack of outward signs does not mean absence of pain.
• Research shows disparities in pain management among racial and ethnic groups, with minority patients often receiving less effective treatment.
• Poorly treated pain increases physiological and psychological costs.
• Pain expression is influenced by social, cultural, emotional, and spiritual concerns.

💊 The Opioid Epidemic

In 2017, the U.S. declared the opioid crisis a Public Health Emergency. Opioids are highly effective for severe pain but carry serious risks, including euphoria, dependence, and addiction.

Opioids produce: analgesia, respiratory depression.

Effective pain management requires weighing risks versus benefits, along with strong emphasis on:

• Evidence-based pain management principles
• Ongoing patient and provider education

📌 Quick Summary

• Aging Adult → pain is common but not normal; undertreatment is common; major causes = arthritis, PVD, cancer, neuropathies.
• Gender → women more sensitive due to hormones; higher risk for migraines & fibromyalgia.
• Cultural → expression varies; use interpreters; disparities in treatment exist.
• Opioids → effective but risky; linked to U.S. epidemic; dependence and addiction possible.

📖 Pain Assessment

🥇 Subjective Report = Gold Standard

Pain is always assessed based on the patient’s self-report. Since pain occurs at a neurochemical level, it cannot be diagnosed solely from physical findings, though exam findings may support the report.

📊 Pain Assessment Tools

• Rate and evaluate all pain sites.
• Use assessment tool consistently.
• Reassessment of pain following intervention is critical in determining clinical response to therapy.
• Standardized overall pain assessment tools are more useful forchronic pain conditions or particularly problematic acute painproblems.Copyright © 2020 by Elsevier Inc. All rights reserved.

Pain is multidimensional — affecting physical, emotional, and functional domains. Assessment tools vary:

• Initial Pain Assessment → 8 open-ended questions covering location, duration, quality, severity, aggravating/relieving factors, expression, and impact on life.
• Brief Pain Inventory → (Last 24 hours) The Brief Pain Inventory (BPI) is a self-report questionnaire used to assess chronic pain. It measures both the severity and impact of pain on daily life.  Rates pain over last 24 hours (0–10 scale) and evaluates impact on mood, sleep, and activity.

📏 Pain Rating Scales (One-Dimensional)

Designed to reflect pain intensity only. Best for tracking progress over time.

• Numeric Rating Scale (NRS) → 0 to 10 / (no pain) to (worst pain).
• Verbal Descriptor Scale (VDS) → patient selects descriptive words.

• Descriptor Scales → patient chooses from a list of descriptive terms.

Choice of scale depends on patient’s age, understanding, and ability.

🔎 PQRST Method of Pain Assessment

A simple structured tool to qualify the patient’s pain experience:

• P → Provocation/Palliation (What makes it better/worse?)
• Q → Quality/Quantity (What does it feel like?)
• R → Region/Radiation (Where is it? Does it spread?)
• S → Severity (Rate the pain, e.g., 0–10)
• T → Timing (When did it start? How long? Pattern?)

📌 Quick Summary

• Subjective report = gold standard.
• Initial assessment asks about location, onset, quality, intensity, factors, impact, reaction, and meaning.
• Tools: Initial assessment, Brief Pain Inventory, McGill Questionnaire.
• Scales: Numeric, verbal, visual analog, descriptor.
• PQRST: Provocation, Quality, Region, Severity, Timing.

🩺 Pain Complaints and Objective Evidence

• Physical findings do not always support a patient’s pain report, especially in chronic pain syndromes.
• Pain should never be discounted simply because no objective evidence is found.
• The nurse must rely on the patient’s self-report and make every effort to reduce or eliminate pain through both analgesics and nonpharmacologic interventions.

🇺🇸 American Pain Society Guidelines

• For acute pain, establishing a diagnosis for the cause is important.
• However, symptomatic treatment should begin immediately — even while the diagnostic process is ongoing.
• Relieving pain improves patient comfort, which in turn increases cooperation with diagnostic procedures and overall care.

📌 Professor’s Note:

✅ Believe the patient’s pain report.

✅ Start treatment early — don’t wait for all tests to confirm the cause.

📚 Pain Assessment – Objective Data

🔎 Objective Data Collection Check for pain.

• Joints → Check for pain. Inspect size, contour, and circumference. Assess active and passive range of motion. Normally, there is no tenderness, pain, or crepitation.
• Muscle and Skin → Check for pain. Inspect for color, swelling, masses, or deformity.
• Abdomen → Check for pain. Observe for contour and symmetry. Palpate for muscle guarding, organ size, and referred pain.

🤐 Nonverbal Behaviors of Pain

When a patient cannot verbally communicate pain, nurses can rely (to a limited extent) on behavioral cues. These vary widely depending on:

• The nature of pain (acute vs. chronic)
• Age
• Cultural and gender expectations

⚡ Acute Pain Behaviors

Acute pain is often associated with autonomic responses and serves a protective purpose. Patients with moderate to severe acute pain may exhibit:

• Vocalizations (moaning, restlessness, agitation, stillness)
• Diaphoresis
• Changes in vital signs (↑ HR, ↑ BP, ↑ RR)

⏳ Chronic Pain Behaviors

Persistent or chronic pain is lived with for months to years, and patients often adapt over time.

• Clinicians cannot rely on typical acute pain behaviors to confirm diagnosis.
• Behaviors are more subtle and variable, increasing the risk of under-detection.
• Associated behaviors:
‣
Bracing, rubbing
1. Diminished activity
‣
Sighing
2. Changes in appetite

📌 Quick Summary

• Objective Data: joints (ROM, contour), muscles/skin (swelling, deformity), abdomen (symmetry, guarding).
• Nonverbal cues: vary by pain type, age, culture, and gender.
• Acute pain → guarding, grimacing, moaning, diaphoresis, VS changes.
• Chronic pain → bracing, rubbing, ↓ activity, sighing, appetite changes.

👵 Developmental Competence: The Aging Adult and Pain

🔹 Pain in Older Adults

• Comorbidities increase the likelihood of pain (e.g., arthritis, osteoporosis, neuropathies).
• Many older adults deny pain due to: fear of dependency, further testing or invasive procedures, financial concerns, fear of addiction or side effects of painkillers

Because of this, nurses must observe functional and behavioral changes that may signal pain rather than relying only on verbal reports.

🧠 Dementia and Pain

• Dementia does not reduce the ability to feel pain, but it impairs the ability to communicate pain verbally.

📌 Quick Summary

• Pain in older adults is common but not normal.
• Watch for behavioral changes (function, mood, activity).
• Dementia → use PAINAD scale (score ≥ 4 = treat).

📌 Quick Summary

• CRPS/RSD → chronic nerve disorder; burning pain + swelling + stiffness + discoloration; treat with medications + physical therapy.
