Family members’ perceptions of pain behaviors and pain management of adult patients unable to self-report in the intensive care unit: A qualitative descriptive study

Does Differential Item Functioning Jeopardize the Comparability of Health-Related Quality of Life Assessment Between Patients and Proxies in Patients with Moderate-to-Severe Traumatic Brain Injury?

BACKGROUND

Health-related quality of life (HRQoL) is clearly recognized as a patient-important outcome in patients with traumatic brain injury (TBI). Patient-reported outcomes are therefore often used and supposed to be directly reported by the patients without interpretation of their responses by a physician or anyone else. However, patients with TBI are often unable to self-report because of physical and/or cognitive impairments. Thus, proxy-reported measures, e.g., family members, are often used on the patient's behalf. Yet, many studies have reported that proxy and patient ratings differ and are noncomparable. However, most studies usually do not account for other potential confounding factors that may be associated with HRQoL. In addition, patients and proxies can interpret some items of the patient-reported outcomes differently. As a result, item responses may not only reflect patients' HRQoL but also the respondent's (patient or proxy) own perception of the items. This phenomenon, called differential item functioning (DIF), can lead to substantial differences between patient-reported and proxy-reported measures and compromise their comparability, leading to highly biased HRQoL estimates. Using data from the prospective multicenter continuous hyperosmolar therapy in traumatic brain-injured patients study (240 patients with HRQoL measured with the Short Form-36 (SF-36)), we assessed the comparability of patients' and proxies' reports by evaluating the extent to which items perception differs (i.e., DIF) between patients and proxies after controlling for potential confounders.

METHODS

Items at risk of DIF adjusting for confounders were examined on the items of the role physical and role emotional domains of the SF-36.

RESULTS

Differential item functioning was evidenced in three out of the four items of the role physical domain measuring role limitations due to physical health problems and in one out of the three items of the role emotional domain measuring role limitations due to personal or emotional problems. Overall, despite an expected similar level of role limitations between patients who were able to respond and those for whom proxies responded, proxies tend to give more pessimistic responses than patients in the case of major role limitations and more optimistic responses than patients in the case of minor limitations.

CONCLUSIONS

Patients with moderate-to-severe TBI and proxies seem to have different perceptions of the items measuring role limitations due to physical or emotional problems, questioning the comparability of patient and proxy data. Therefore, aggregating proxy and patient responses may bias HRQoL estimates and alter medical decision-making based on these patient-important outcomes.

Development and preclinical testing of the critical care pain observation tool for family caregiver use (CPOT-Fam)

Background and Aims

Pain assessment in noncommunicative intensive care unit (ICU) patients is challenging. For these patients, family caregivers (i.e., family members, friends) may be able to assist in pain assessment by identifying individualistic signs of pain due to their intimate patient knowledge. This study adapted the critical care pain observation tool (CPOT) to facilitate pain assessment in adult ICU patients by family caregivers.

Methods

This study was conducted through three distinct phases: (1)CPOT adaptation for family caregiver use (to create the CPOT-Fam): A working group met monthly to adapt the CPOT and develop educational material and sample cases for practice scoring until consensus was reached.(2)CPOT-Fam preclinical testing: Family caregiver study participants viewed educational materials and scored four randomly selected sample cases using the CPOT-Fam. Scores were compared to reference scores to assess agreement and identify CPOT-Fam sections requiring revision. Open-ended feedback on the CPOT-Fam was collected.(3)CPOT-Fam revision: the CPOT-Fam was revised by the working group considering score agreement and feedback received from study participants.

Results

Of the n = 30 participants, n = 14 (47.0%) had experience with an ICU patient. Agreement between CPOT-Fam participant scores and reference scores were highest for the vocalization dimension (Is the patient making any sounds?; Intraclass correlation coefficient; ICC = 1.0) and lowest for the body movements dimension (What are the patient's body movements like?; ICC = 0.85. Participants indicated they found the CPOT-Fam to be "informative" and "easy-to-use" but "not graphic enough"; participants also indicated that descriptors like "lack of breath" and "struggling to move" are helpful with identifying individualistic behaviors of pain exhibited by their loved ones.

Conclusion

The CPOT-Fam shows ease of use and may be of value in involving family caregivers in ICU care. Clinical pilot testing is needed to determine feasibility and acceptability and identify further areas for refinement.

Interprofessional Healthcare Students' Attitudes, Skills, and Knowledge After Comprehensive Pain Assessment Training in Verbal and Nonverbal Patients

A comprehensive pain assessment is the first step in safe, effective pain management. Few studies have explored variations of strategies and measures for multidimensional pain assessment education in both verbal and nonverbal patients. In this retrospective cohort study, interprofessional health care students enrolled in a palliative care curriculum completed a pain assessment training, which taught the PQRSTA ("palliating factors, precipitating factors, previous treatments, quality, region, radiation, severity, temporal factors and associated symptoms") mnemonic as a strategy for assessing pain in verbal patients and the Pain Assessment in Advance Dementia and Checklist of Nonverbal Pain Indicators measures for nonverbal patients. The purpose of this study was to compare the change in attitudes, self-perceived skills, and knowledge regarding pain assessment before and after the training. Attitudes and self-perceived skills were assessed in the pretraining and posttraining survey, which was analyzed using χ2 test or Fisher exact test. Students' knowledge responses were analyzed using Wilcoxon signed rank test to assess accuracy of responses compared with the expert defined score. One hundred eighty-two students were included. Results showed a statistically significant improvement in attitudes related to applicability of pain measures and self-perceived skills. Overall, data did not support an increase in knowledge using the PQRSTA mnemonic, or Pain Assessment in Advance Dementia and Checklist of Nonverbal Pain Indicators measures. Future pain trainings should consider training on only 1 nonverbal pain measure, incorporating bedside assessments, and integrating real-time feedback.

Current Perspectives on the Assessment and Management of Pain in the Intensive Care Unit

Critical illness is often painful, both from the underlying source of illness, as well as necessary procedures performed for the monitoring and care of these patients. Pain is often under-recognized in the critically ill, especially among those who cannot self-report, so accurate assessment and management continue to be major consideration in their care. Pain management in the intensive care unit (ICU) is an evolving practice, with a focus on accurate and frequent pain assessment, and targeted pharmacologic and non-pharmacologic treatment methods to maximize analgesia and minimize sedation. In this review, we will evaluate several validated methods of pain assessment in the ICU and present management options. We will review the evidence-based recommendations put forth by the largest critical care societies and several high-quality studies related to both the in-hospital approach to pain, as well as the short- and long-term consequences of untreated pain in ICU patients. We conclude with future directions.

Role of Family Members in Pain Management in Adult Critical Care

This review describes family member involvement in intensive care unit pain assessment and management and generates implications for clinical practice, education, and future research. A literature review was performed in MEDLINE, PubMed, EMBASE, Cochrane, and CINAHL databases from their inception until April 30, 2019. Only 11 studies addressing the topic were identified, and the current quality of evidence is low. Family members can be involved in pain assessment by describing patients' pain behaviors and in pain management by selecting and delivering nonpharmacological interventions tailored to patients' needs, if the family members feel comfortable with this role. More-rigorous research is required to describe the role of family members in patients' pain assessment and management. Advancing knowledge in this field could improve patients' and family members' experiences with pain assessment and management in the intensive care unit.

The Effect of Music on Pain in the Adult Intensive Care Unit: A Systematic Review of Randomized Controlled Trials

CONTEXT

Multimodal analgesic approaches are recommended for intensive care unit (ICU) pain management. Although music is known to reduce pain in acute and chronic care settings, less is known about its effectiveness in the adult ICU.

OBJECTIVES

Determine the effects of music interventions on pain in the adult ICU, compared with standard care or noise reduction.

METHODS

This review was registered on PROSPERO (CRD42018106889). Databases were searched for randomized controlled trials of music interventions in the adult ICU, with the search terms ["music*" and ("critical care" or "intensive care")]. Pain scores (i.e., self-report rating scales or behavioral scores) were the main outcomes of this review. Data were analyzed using a DerSimonian-Laird random-effects method with standardized mean difference (SMD) of pain scores. Statistical heterogeneity was determined as I² > 50% and explored via subgroup analyses and meta-regression.

RESULTS

Eighteen randomized controlled trials with a total of 1173 participants (60% males; mean age 60 years) were identified. Ten of these studies were included in the meta-analysis based on risk of bias assessment (n = 706). Music was efficacious in reducing pain (SMD -0.63 [95% CI -1.02, -0.24; n = 10]; I² = 87%). Music interventions of 20-30 minutes were associated with a larger decrease in pain scores (SMD -0.66 [95% CI -0.94, -0.37; n = 5]; I² = 30%) compared with interventions of less than 20 minutes (SMD 0.10 [95% CI -0.10, 0.29; n = 4]; I² = 0%). On a 0-10 scale, 20-30 minutes of music resulted in an average decrease in pain scores of 1.06 points (95% CI -1.56, -0.56).

CONCLUSION

Music interventions of 20-30 minutes are efficacious to reduce pain in adult ICU patients able to self-report.

Pain Assessment in the Patient Unable to Self-Report: Clinical Practice Recommendations in Support of the ASPMN 2019 Position Statement

Pain is a subjective experience, unfortunately, some patients cannot provide a self-report of pain verbally, in writing, or by other means. In patients who are unable to self-report pain, other strategies must be used to infer pain and evaluate interventions. In support of the ASPMN position statement "Pain Assessment in the Patient Unable to Self-Report", this paper provides clinical practice recommendations for five populations in which difficulty communicating pain often exists: neonates, toddlers and young children, persons with intellectual disabilities, critically ill/unconscious patients, older adults with advanced dementia, and patients at the end of life. Nurses are integral to ensuring assessment and treatment of these vulnerable populations.

Family Members' Experiences with Observing Pain Behaviors Using the Critical-Care Pain Observation Tool

BACKGROUND

Current guidelines support family members' participation in care, but little is known regarding their potential contribution to pain assessment using validated behavioral pain scales.

AIMS

This study aimed to describe family members' observations of pain behaviors with the Critical-Care Pain Observation Tool and their evaluation of the tool and its use, and to understand their experience and perceptions of their potential role in pain management in the intensive care unit.

DESIGN

A mixed methods cross-sectional explanatory design was used.

SETTING

A medical-surgical intensive care unit in Canada.

PARTICIPANTS/SUBJECTS

Family members were eligible if they had a loved one admitted in the intensive care unit who was unable to self-report.

METHODS

Family members identified pain behaviors using the Critical-Care Pain Observation Tool after a brief training, completed a self-administered questionnaire, and participated in a follow-up individual interview regarding their experience and perceived potential role in pain management when their loved one is unable to self-report.

RESULTS

Ten family members participated. A 15-minute training appeared sufficient for family members to be comfortable with observing pain behaviors included in the Critical-Care Pain Observation Tool. The tool allowed them to confirm their observations of pain behaviors, to focus more on the patient, and to advocate for better pain management.

CONCLUSIONS

Future research is needed to explore the views of more family members and to compare their Critical-Care Pain Observation Tool scores to the ones of nurses' for interrater reliability testing.
