Chapter 2 Symptom & Psychosocial Management

Pain Assessment & Pharmacologic Interventions

Pain is one of the most common and distressing symptoms experienced by patients receiving hospice and palliative care. It is both a physical and emotional experience and can be deeply personal. Effective pain management is central to the work of hospice and palliative nurses, who must assess pain thoroughly and implement pharmacologic interventions appropriately. In this section, we will explore the fundamental principles of pain assessment and the most commonly used pharmacologic strategies to alleviate pain in individuals with serious or terminal illnesses. All explanations are geared toward preparing nurses for the Certified Hospice and Palliative Nurse (CHPN) Exam, and are presented in clear, easy-to-understand language.

Understanding Pain in Palliative Care

Pain in hospice and palliative care settings may be acute, chronic, or breakthrough. It can arise from the illness itself, treatment side effects, or unrelated conditions. Because patients may experience multiple sources and types of pain, it's critical to perform comprehensive pain assessments. In palliative care, pain is not just physical-it can be influenced by emotional, social, cultural, and spiritual factors. This makes a holistic approach to assessment and treatment necessary.

Principles of Pain Assessment

Pain assessment in palliative care should be frequent, consistent, and individualized. Nurses should use both subjective and objective measures to understand the patient's pain experience. Subjective assessment involves asking the patient to describe their pain, while objective assessment includes observing behavior and physiological signs.

One of the foundational principles in pain assessment is the belief that pain is what the patient says it is. Therefore, patient self-reporting is the most reliable indicator of pain. Validated tools such as the Numeric Rating Scale (NRS), the Visual Analog Scale (VAS), and the Faces Pain Scale-Revised (FPS-R) help quantify pain levels. For patients who are unable to communicate verbally, such as those with advanced dementia or near the end of life, observational tools like the PAINAD (Pain Assessment in Advanced Dementia) scale are used.

Key aspects to assess include:

• Location: Where is the pain?
• Intensity: How severe is it on a scale of 0-10?
• Quality: Is it sharp, dull, throbbing, burning?
• Onset and duration: When did it start and how long does it last?
• Aggravating and relieving factors: What makes it worse or better?
• Impact on function: How does the pain affect daily activities and mood?

Nurses must also be aware of cultural influences on how pain is expressed and managed. Some patients may underreport pain due to cultural stoicism or fear of addiction. Open, respectful communication can help bridge these gaps.

Pharmacologic Interventions in Pain Management

Once pain has been assessed thoroughly, pharmacologic interventions are used as part of a broader, individualized pain management plan. Medications must be chosen based on the type of pain (nociceptive vs. neuropathic), severity, and patient-specific factors such as organ function and previous response to analgesics.

Types of Pain and Corresponding Medications

• Nociceptive Pain: This is the most common type of pain in palliative care and includes somatic (musculoskeletal, skin) and visceral (organ) pain. It is usually well localized and described as aching, throbbing, or cramping. Opioids and non-opioid analgesics are typically effective for this type.
• Neuropathic Pain: This arises from nerve damage and is described as burning, tingling, or shooting. Neuropathic pain often requires adjuvant medications such as anticonvulsants (e.g., gabapentin) or antidepressants (e.g., amitriptyline) in addition to opioids.

The World Health Organization (WHO) Pain Ladder

The WHO pain ladder is a guideline used internationally to treat cancer and chronic pain. It consists of a three-step approach:

• Step 1: Mild pain - non-opioid analgesics (e.g., acetaminophen, NSAIDs)
• Step 2: Moderate pain - weak opioids (e.g., codeine, tramadol) + non-opioid
• Step 3: Severe pain - strong opioids (e.g., morphine, hydromorphone) + non-opioid

Adjuvants can be added at any step to enhance pain relief or treat specific types of pain, particularly neuropathic pain.

Opioid Use in Palliative Care

Opioids are a cornerstone of pharmacologic pain management in hospice and palliative care. They include medications such as morphine, oxycodone, hydromorphone, fentanyl, and methadone. These drugs bind to opioid receptors in the central nervous system to block the perception of pain.

When using opioids, the nurse must consider:

• Equianalgesic dosing: Knowing how to convert between different opioids and routes of administration to ensure safe and effective pain control.
• Routes of administration: Oral, subcutaneous, intravenous, transdermal, rectal, and sublingual forms are commonly used depending on the patient's condition.
• Titration and tolerance: Starting low and going slow is the rule, but regular reassessment and adjustment are necessary.
• Side effects management: Common side effects include constipation, nausea, sedation, and respiratory depression. These should be anticipated and treated proactively. For instance, bowel regimens are typically started with opioid therapy to prevent constipation.

Breakthrough Pain Management

Breakthrough pain is a sudden flare of pain that occurs despite ongoing pain medication. It can be predictable (e.g., related to movement) or unpredictable. Nurses must be prepared to administer short-acting opioids for breakthrough episodes, typically using 10-15% of the total daily opioid dose. Frequent breakthrough episodes may indicate the need to increase the baseline dose.

Adjuvant Medications

Adjuvants are drugs that are not primarily used for pain but can enhance analgesic effects, relieve other symptoms, or treat specific types of pain. Examples include:

• Antidepressants: Useful for neuropathic pain (e.g., amitriptyline, duloxetine)
• Anticonvulsants: Treat nerve pain (e.g., gabapentin, pregabalin)
• Corticosteroids: Reduce inflammation and pain from tumors or spinal cord compression
• Muscle relaxants: For musculoskeletal spasms

These medications are often combined with opioids for synergistic effects and improved symptom control.

Pediatric and Geriatric Considerations

Pain assessment and management in children and older adults require special attention. In children, tools such as the FLACC scale (Face, Legs, Activity, Cry, Consolability) are used for non-verbal patients. In older adults, age-related changes in drug metabolism must be considered, and the risk of polypharmacy is higher.

In both populations, clear communication with caregivers is essential. Doses are often weight-based in children, while geriatric patients may require lower starting doses and more careful monitoring.

Barriers to Effective Pain Management

Several barriers can hinder pain management in palliative care:

• Fear of addiction or tolerance: Patients and families may resist opioid use due to misconceptions.
• Regulatory concerns: Strict laws and documentation requirements may discourage appropriate prescribing.
• Healthcare provider discomfort: Some clinicians may be hesitant to escalate opioid doses.

Education is key. Nurses play an essential role in advocating for patients, educating families, and promoting evidence-based pain management strategies.

Role of the Hospice and Palliative Nurse

Nurses are on the front lines of pain management. They assess pain regularly, administer medications safely, monitor for side effects, educate patients and families, and collaborate with the interdisciplinary team. They also advocate for timely adjustments in therapy and ensure that pain relief aligns with the patient's goals of care.

Pain management is not about eliminating all pain at all costs, especially if the side effects impair the patient's quality of life. Instead, the goal is comfort, dignity, and maximizing quality of life. This often requires ongoing communication, creative problem-solving, and a compassionate approach.

Conclusion

Pain assessment and pharmacologic interventions are foundational skills for hospice and palliative care nurses. Understanding the different types of pain, how to assess them, and the appropriate use of medications ensures that patients receive compassionate and effective care. For those preparing for the CHPN exam, mastering these concepts not only improves test performance but also enhances clinical practice. Pain management is both a science and an art-requiring technical knowledge, emotional intelligence, and ethical commitment to relieving suffering.

Non-Pain Symptom Management (e.g., Dyspnea, Nausea, Delirium)

In hospice and palliative care, while pain management is often at the forefront, managing non-pain symptoms is just as essential to improving a patient's quality of life. Many patients with serious or life-limiting illnesses suffer from symptoms such as dyspnea (shortness of breath), nausea and vomiting, and delirium. These symptoms can be distressing, interfere with daily function, and decrease a person's dignity at...
