Cancer-Related Pain Assessment: Monitoring the Effectiveness of Interventions

Evaluation of the Glymphatic System With Diffusion Tensor Imaging-Along the Perivascular Space in Cancer Pain

Cancer pain (CP) is one of the most common symptoms affecting life quality, and there is considerable variation in pain experience among patients with malignant tumors. Previously, it has been found that the fluid drainage function in the brain can be regulated by peripheral pain stimulation. However, the relationship between cancer pain and functional changes of the glymphatic system (an important pathway for fluid drainage in the brain) remains unclear. In this study, 97 participants were enrolled, which included 40 participants in the cancer pain (CP) group, 27 participants in the painless cancer (PLC) group and 30 participants in the control (NC) group. Differences in glymphatic system function among the three groups and between before and after pain pharmacological intervention were analyzed by measuring diffusivity and the index along the perivascular space (ALPS index) using diffusion tensor imaging. We found that diffusivity and the ALPS index were significantly lower in the CP group than in the PLC and NC group and increased following intervention with pain relief. Moreover, the ALPS index was negatively correlated with the degree of pain in the CP group. The present study verified that alterations in glymphatic function are closely related to cancer pain, and the quantification of functional changes reflects pain severity. Our findings support the use of neuroimaging biomarkers for cancer pain assessment and indicate that pain can be alleviated by regulating brain function status.

Effects of nurse-led nonpharmacological pain interventions for patients with cancer: A systematic review and meta-analysis

PURPOSE

The purposes of this study were to review the types of nurse-led nonpharmacological pain interventions (NPI) offered to cancer patients and/or family caregivers, and to determine a comprehensive and robust estimate of the effect size of nurse-led NPI for cancer patients on various pain-related outcomes.

DESIGN

Systematic review and meta-analysis. Studies assessing nurse-led NPIs targeting cancer patients and published between January 2008 and December 2020 were identified by searching multiple literature databases, including MEDLINE^® , EMBASE, Google Scholar, Cochrane Library, ProQuest Medical Library, and CINAHL^® .

METHODS

This review was conducted in accordance with the Preferred Reporting Item for Systematic Reviews and Meta-analyses guidelines. The selected randomized clinical trials were independently assessed for methodological quality. The effect sizes (ESs) of treatment were presented as standardized mean differences (Hedges' g) and 95% confidence intervals (CIs).

FINDINGS

A meta-analysis was performed to analyze data from 22 randomized clinical trials. Three types of nurse-led NPI were offered, mainly to cancer patients but also to some caregivers: music, physical, and psycho-educational interventions. The dose and duration of nonpharmacological interventions varied widely. The study participants ranged in age from 44.1 to 67.3 years. Meta-analysis indicated that, although these interventions had small effects in long-term (g = 0.24, 95% CI: 0.06-0.43, p = 0.011) to medium effects in short-term (g = 0.43, 95% CI: 0.32-0.53, p < 0.001), they significantly reduced patients' pain, increased their knowledge of pain management, reduced barriers to pain management and pain coping, and improved other physical and emotional symptoms. The significance of the ES differed according to the type of intervention, with psycho-educational and physical NPIs having a significant but medium short-term ES, whereas music NPI had a significant but large short-term ES. Only psycho-educational NPIs had significant long-term effects.

CONCLUSION

The combined ES showed that these nurse-led NPIs were significantly effective in both the short and long-term. Types of intervention as a potential moderator were associated with short-term and long-term effects of nonpharmacological interventions on patient outcomes.

CLINICAL RELEVANCE

Research-tested interventions should be provided to help patients cope effectively with pain.

Nonwearable actigraphy to assess changes in motor activity before and after rescue analgesia in terminally ill patients with cancer: A pilot study

AIMS

This study aimed to investigate the usefulness of nonwearable actigraphy to assess changes in motor activity before and after rescue analgesic administration in terminally ill cancer patients.

BACKGROUND

Evaluating pain in terminally ill cancer patients is difficult; pain assessment tools are needed.

METHODS

This was an exploratory descriptive study conducted within a palliative care unit. A nonwearable actigraph was used to measure the activity score and movement index of terminally ill patients with weeks-long prognosis and pain. The actigraph and medical data were integrated, and data were compared 6 h before and after rescue analgesic administration.

RESULTS

Among 10 patients (age: 75.8 ± 12.3 years; six men), we evaluated 28 pain episodes (mean activity score: 130.9 ± 180.5 counts per minute; movement index: 68.8%). When pain was relieved at night following rescue analgesic administration, activity score and movement index decreased significantly (6 h before vs. 6 h after analgesics, respectively: 113.1 to 69.7 counts per minute; 64.3% to 41.8%; both p < 0.0001). With no relief after rescue analgesic administration, activity score did not differ significantly 6 h before and after analgesics: 147.3 to 137.7 counts per minute.

CONCLUSION

Pain in terminally ill cancer patients could be assessed using a nonwearable actigraph to capture motor activity and improve pain assessment.

The IPA, a Modified Numerical System for Pain Assessment and Intervention

The objective of this study was to (1) construct a pain scale that improves communication between healthcare providers and patients (Interventional Pain Assessment [IPA] tool) and (2) to validate this new pain scale with the numeric rating scale of 0 to 10 Numerical Rating System (NRS).

Opioid Misuse: An Organizational Response While Managing Cancer-Related Pain

BACKGROUND

Opioids are commonly prescribed to manage cancer pain. Similar to the general population, patients with cancer are not excluded from the risk for opioid misuse and dependence. This situation can contribute to clinician reluctance to prescribe and manage pain using opioids.

OBJECTIVES

The purpose of this article is to provide an overview of how opioid misuse may affect pain management in patients with cancer and to describe a comprehensive cancer center's approach to safely managing cancer pain.

METHODS

Based on a literature review, the project team developed a stewardship program. Project components included selecting a validated screening tool for risk of opioid misuse, determining if a history of addiction affects pain management in patients with cancer, and establishing a task force to focus on the opioid crisis and to follow the Joint Commission's revised pain assessment and management standards.

FINDINGS

The project established a hospitalwide opioid stewardship program. Through the use of a multidisciplinary, universal precautions approach to assessing misuse in all patients with cancer who are prescribed opioids, healthcare teams can potentially reduce risks associated with misuse while safely managing cancer pain.

Pain Knowledge and Attitudes Among Nurses in Cancer Care in Norway

The purpose of this study was to survey knowledge on, and attitudes to, pain and pain management among a cohort of Norwegian Nurses in cancer care, and to explore whether there is any association between various demographic variables and knowledge level. This is a web-based survey and nurses were recruited from the Forum for Cancer Nursing. Nurses completed the questionnaire "Nurses' Knowledge and Attitudes Survey Regarding Pain (NKAS)". Univariate and multivariate linear regression analysis were used to evaluate the association between knowledge and attitudes and demographic variables. Nurses from all over Norway answered. The majority were women and most had education above bachelor level. Mean NKAS total score was 31 points (75%). Significant associations were found between NKAS total score and pain management course (p = 0.01) and workplace (p = 0.04). Nurses in cancer care in Norway have relatively good pain knowledge. The potential for improvement is the greatest with regard to pharmacology and nurses' attitudes to how patients express pain. Our findings suggest that an extensive pain management course with patient histories may result in more theoretical knowledge being applied to the patients. In a time with large migration among nurses, our findings indicate that pain management courses should be aware of cultural differences in the educational training.

Pain Management in the Cancer Survivor

OBJECTIVES

To describe assessment and interdisciplinary management of pain in the cancer survivor over the continuum of cancer care.

DATA SOURCES

Review of the literature and treatment standards.

CONCLUSION

Pain remains a primary concern throughout the cancer trajectory across all age groups and diagnoses, emphasizing the need to integrate pain assessment and management across the continuum of cancer survivorship and across care settings. Types of pain, pain patterns, assessment of cancer pain in cancer survivors, current strategies and challenges for management, and effective communication and documentation of the process are described. Communication between and among health care clinicians in a way that effectively articulates the individual patient experience, including documentation in the electronic medical record, requires consistent workflows and terminology. The opioid crisis increases the urgency in effective strategies for interdisciplinary pain assessment and management.

IMPLICATIONS FOR NURSING PRACTICE

Oncology clinicians must be able to adequately assess pain, track pain over time, understand and implement a cadre of strategies to manage pain, and effectively pursue any suspicious pain patterns that may indicate recurrence or progression of cancer or other underlying etiologies. The oncology nurse is at the core of patient-clinician communication, critical to effectively describing pain as experienced by the individual patient and continues to play a key role in maintaining consistency of message that is necessary to manage pain over the continuum of cancer survivorship.

Assessment and Management of Cancer Pain in Older Adults: Strategies for Success

Pain is a significant problem in older adults with cancer as older adults often receive suboptimal pain management. While overmedication can lead to adverse effects, under management of pain can lead to physiological and psychological problems such as functional decline and depression. This manuscript will discuss the assessment and management of pain in older adults, in consideration of the pharmacodynamic changes related to aging and other individual considerations. Current evidence from filtered and unfiltered sources, PubMed, current guidelines. Unrelieved pain can have a detrimental impact on older adults. A team approach is essential to assess patients at each encounter, consider the social environment in which the patient resides, and employ pharmacologic and nonpharmacologic strategies that are evidence-based and are tailored to the specific cancer pain syndrome.
