Challenges in Pain Assessment

More than 50 million surgical procedures are performed each year in the United States to relieve a wide range of maladies. Depending on the type of surgery, a portion of these patients will suffer from acute post-surgical pain that, unless effectively managed, may delay the patient’s recovery and lead to chronic pain. A significant number of patients continue to experience unrelieved postoperative and procedural pain despite the identification of contributing factors and the development of treatment guidelines. As the Joint Commission mandates the assessment and treatment of pain, clinicians and institutions are required to give increased attention to the proper management of pain in the surgical population. In response to this mandate, the field of post-surgical pain relief has undergone a conceptual revolution that now provides clinicians with the opportunity to evaluate the multiple dimensions of postoperative pain and to investigate the mechanisms that underlie this complex phenomenon. By validating the experience of these patients and developing a greater understanding of the pathophysiology of postoperative pain, it is expected that treatments will become more effective and patient outcomes will be improved. However, no amount of assessment or evaluation will diminish the frustration and disappointment of both the clinician and the patient when the pain management is less than optimum. The inability to adequately reduce acute postoperative pain, the initial predisposing factor to the development of chronic pain, leads to increased morbidity, prolongs the patient’s recovery, and impacts healthcare costs. It is time to reevaluate the way that pain is assessed and quantified in the postoperative and procedural setting. The first instinct of many clinicians when addressing the issue of pain is to ask the patient to describe the location, quality, and intensity of his or her pain. Unfortunately, this approach is limited as language may be inadequate to convey such information, and an intellectual understanding of pain may not truly capture the totality of a patient’s subjective experience. Furthermore, physiological, cognitive, affective, and other psychological responses to pain are each measurable. Therefore, when developing comprehensive postoperative pain relief protocols, researchers must consider how to develop studies to simultaneously address the sensory, affective, evaluative, and other response components of postoperative pain.

1.1. Lack of Objective Measures

It is important to continue to explore and study innovative pain assessment modalities so that more options are available for health care professionals with varying patient populations and contextual factors. To better manage the lack of objective measures, we need more interdisciplinary research to push the boundaries of clinical knowledge forward. We need to adapt both our assessment methodologies and broader conceptual frameworks of pain to the latest technologies and scientific discoveries. Moreover, we should ensure research efforts to be inclusive and sensitive to the needs of diverse groups of patients as well as their healthcare providers. By bringing together expertise from disciplines such as neuroscience, psychology, biomedical engineering, and data science, we can develop a healthcare model centered around continuous individualized pain management.

Another approach to overcoming the lack of objective measures is to enhance pain assessment through the use of technology. New technologies such as three-dimensional virtual reality experience, computerized gait analysis, and telemedicine have been used to attempt to provide more objective data on pain sensations and functional tolerances in the patient. However, the use of such technologies has not yet been widespread or standardized, and effective use of these would require interdisciplinary research efforts to develop and validate them for clinical practice. Such developing technologies have been applied mostly in sports and military medicine. Teleconsultation with a specialist based in a different geographical location may be more feasible in those populations.

However, since current pain assessment tools are not comprehensive and are often used inconsistently, experts are advocating for the development of new tools that take into account the variety of dimensions that may characterize the pain experience. For example, it has been suggested that electroencephalogram (EEG) based measures of brain activity might be a possible objective measure of pain in clinical settings. By using machine-learning techniques to develop pain scales based on brain activity, objective measures of pain may become a reality in the future.

In such cases, validated pain assessment tools like the “Pain Assessment in Advanced Dementia Scale” (PAINAD) should be used. The PAINAD includes five items that are scored from 0 to 2 or 0 to 3, and scores are summed for a total score of 0 to 10. These five items include breathing, negative vocalization, facial expression, body language, and consolability. It is designed for patients with dementia who cannot clearly articulate or express their pain and helps to guide the selection of analgesics by indicating the presence or absence of pain.

One of the main challenges health care professionals face in pain management is the lack of objective measures. Pain is a subjective sensation that is difficult to objectively assess. Pain cannot be seen or measured by instruments like vital signs, so clinicians rely on patient self-reporting and surrogate markers of pain, such as changes in facial expression or limitations in functional abilities. However, self-reporting is not always reliable, and these surrogate markers do not always reflect the presence or severity of pain. This is especially problematic in cases of conditions like dementia, where some patients may have communication barriers and may not be able to self-report their pain.

1.2. Subjective Nature of Pain Reports

Pain, unlike other vital signs such as blood pressure and heart rate, cannot be measured objectively. There is no standard test that can measure and locate pain precisely. Moreover, what a person reports as pain will be based on their subjective experience of the pain, and this is what makes the assessment of pain a little bit complex. Each individual’s pain is a unique experience, and this is because pain is composed of a number of personal factors: cultural background, previous experiences, gender, and age all can have an influence on how much pain a person actually feels at any one time. For example, two people with the same sort of injury and visible damage, that is an injury to the skin that is painful to touch, might feel quite different levels of pain, purely because the sensations and experiences following pain can be affected by many different things, and this individual self-reporting can be complicated at times, especially in people with communication or cognitive deficit. As per McCaffery (1968), pain is whatever the experiencing person says it is, existing whenever he says it does. This basically means that the best indicator of the existence of the pain is the patient’s verbal report and the best measure of the intensity of the pain is the patient’s own rating of the pain, rather than the observations of the healthcare professional. On the other hand, some healthcare professionals see self-reporting as the sole measure of pain and effectively ignore non-verbal indicators that a patient may be in pain, particularly in elderly people. For instance, elderly adults are not able to discriminate pain intensity as well as younger adults. It is argued that the assessment of pain by nurses is less accurate in older adults because people tend to attribute facial signs of pain in older adults to the normal aging process. This may describe the difference in how pain is managed and assessed in elderly people. In acute care, adults aged 60 years and older were significantly less likely than younger adults to receive any analgesics for pain. This points to healthcare professional biases and non-effective pain assessment methods. McCaffery and Beebe (1989) mentioned that the single most reliable indicator of the existence of such sensation is the individual’s own report and that can be successfully amplified and transferred from the individual to the healthcare professional. This suggests that health professionals pay attention to patients’ self-reporting and act upon this and come to a conclusion on how best to help the patient from there. However, it is important for healthcare professionals to take into consideration the whole clinical picture as well, that is, both self-reporting of the patient and also medical observations.

1.3. Communication Barriers with Non-Verbal Patients

The 1.3. Communication Barriers with Non-Verbal Patients focuses on the different ways non-verbal patients communicate their pain and the difficulties in assessing and managing the pain in non-verbal patients. Non-verbal patients could include patients who suffer from conditions such as dementia, brain injuries or babies who are not old enough to speak. In many cases, non-verbal patients would use self-injurious behavior to communicate their pain, such as hitting or biting themselves. However, it is important to note that self-injurious behavior is not equivalent to self-harm behavior. All behaviors, such as hitting and biting, would be considered as challenging behavior commonly associated with a lack of adaptive skills in non-verbal patients with intellectual developmental disorder. To better help non-verbal patients, healthcare professionals should focus on patient management when dealing with challenging behaviors. Good communication does not always mean one person speaks while the other is listening. Non-verbal communication is an important component for understanding the patients’ feelings and needs. Healthcare professionals and carers should pay attention and identify the needs and emotions expressed by different types of non-verbal communication, such as crying, groaning or changes in facial expressions. Over the last few decades, various types of behavioral pain assessment scales have been developed and validated for measuring pain intensity in non-verbal patients. Some common types of behavioral pain assessment scales include the non-communicative children’s pain checklist, the non-verbal pain scale and the pain assessment checklist for seniors with limited ability to communicate. These behavioral pain assessment scales provide descriptions and instructions for healthcare professionals to identify pain-related behaviors and rate the pain intensity based on different observations. The use of different pain assessment scales varies depending on the age group and the ability of patients to follow commands. For instance, the non-communicative children’s pain checklist is designed for children aged from 3 to 18 years old with severe cognitive impairments and the inability to self-report pain.
