Development and Content Validation of the Communication, Organization, and Intrafamilial Beliefs in Neonatology Scale for Family Resilience in the Neonatal Intensive Care Unit

Background and Purpose: Family resilience in the neonatal intensive care unit (NICU) is a promising avenue for promoting parental mental health, yet no tool is available to assess it. This study aimed to develop a new scale to measure family resilience in French-speaking parents during the NICU hospitalization and evaluate content validation. Methods: This methodological study was conducted in Quebec and included two phases: (a) item development process and (b) content validity evaluation process using successive quantitative and qualitative methods. A total sample of 14 experts evaluated item clarity, relevance, and representativeness on 1-4 rating scales and provided qualitative feedback on scale characteristics. Results: An initial scale of 55 items was developed. Excellent content validity (Scale Content Validity Index > .90) and consensus regarding item selection and scale presentation were achieved. Conclusions: This content-validated 55-item Communication, Organization, and Intrafamilial Beliefs in Neonatology (COCINL) scale should be psychometrically tested in the Quebec NICU parent population.

Association Between Pupil Light Reflex and Delirium in Adults With Traumatic Brain Injury: Preliminary Findings

ABSTRACT

BACKGROUND: Delirium is a common neurological complication in patients admitted to the intensive care unit (ICU) after moderate to severe traumatic brain injury (TBI). Although current clinical guidelines prioritize delirium prevention, no specific tool is tailored to detect early signs of delirium in TBI patients. This preliminary 2-phase observational study investigated the correlation between the pupillary light reflex (PLR), measured with a pupillometer during mechanical ventilation, and the development of postextubation delirium in TBI patients. METHODS: A convenience sample of 26 adults with moderate to severe TBI under mechanical ventilation was recruited during their ICU stay. In phase I, PLR measurements were performed in the first 3 days of ICU admission using automated infrared pupillometry. In phase II, 2 raters independently extracted delirium data in the 72 hours post extubation period from medical records. Delirium was confirmed with a documented medical diagnosis. Point-biserial correlations ( rpb ) were used to examine the association between PLR scores and the presence of postextubation delirium. Student t tests were also performed to compare mean PLR scores between patients with and without delirium. RESULTS: Ten TBI patients (38%) were diagnosed with postextubation delirium, whereas 16 (62%) were not. Significant correlations between delirium and 2 PLR variables were found: pupil constriction percentage ( rpb (24) = -0.526, P = .006) and constriction velocity ( rpb (24) = -0.485, P = .012). The t test also revealed a significant difference in constriction percentage and velocity scores between TBI patients with and without delirium ( P ≤ .01). CONCLUSION: Our findings suggest that the use of pupillometry in the first 3 days of mechanical ventilation during an ICU stay may help identify TBI patients at risk for delirium after extubation. Although further research is necessary to support its validity, this technological tool may enable ICU nurses to better screen TBI patients for delirium and prevent its development.

Adaptation and Validation of the Standardized Swallowing Assessment Tool for Patients With Moderate-Severe Traumatic Brain Injury and Cervical Spinal Cord Injury

Oropharyngeal dysphagia is common in moderate-severe traumatic brain injury (TBI) and cervical spinal cord injury (SCI) patients and can have serious consequences. Delaying feeding in these patients can also be detrimental. Nonetheless, the psychometric properties of screening tools that can promptly identify dysphagia have never been tested in these neurotrauma populations. This study aimed to: (1) adapt, translate, and validate the content of the French-Canadian version of the the Standardized Swallowing Assessment (SSA) tool to meet the needs of moderate-severe TBI and cervical SCI patients, (2) examine its inter-rater reliability and criterion-concurrent validation, and (3) evaluate its clinical utility from the perspectives of critical care nurses. The SSA tool was adapted and translated using an integrated method for the cultural adaptation and translation of tools. Eleven experts participated in the adaptation of the SSA tool, which led to the clarification of one item, as well as a new step and instructions for the screening procedure. Content validation (i.e., item and scale relevance) was evaluated by multidisciplinary team members (n = 17). The mean content validity index (CVI) score was 0.97 for the entire scale, while the mean CVI scores for individual items ranged from 0.82 to 1.0. A total of 60 neurotrauma patients were enrolled for inter-rater reliability and criterion-concurrent validation. Interrater reliability was determined by comparing two scores: one score from nurses responsible for the care of enrolled patients and one score from the research nurse. The weighted kappa coefficients for inter-rater reliability were 0.86 for moderate-severe TBI patients (n = 30) and 0.73 for cervical SCI patients (n = 30). A speech language therapist (SLT) also assessed dysphagia and results were used as the standard clinical reference criterion to determine concurrent validity (sensibility and specificity) of the adapted SSA tool. The sensitivity and specificity were 92% and 50% for moderate-severe TBI, and 77% and 75% for cervical SCI, respectively. The positive predictive value (PPV) and the negative predictive value (NPV) were 65% and 87% in TBI patients, and 75% and 76% in SCI patients. Test accuracy was 71% and 77% for these same groups. The clinical utility of the tool was evaluated according to the following domains: appropriateness, accessibility of the required material, applicability, perceived effectiveness, and acceptability. Acceptability was the only domain with a level of agreement <80% (74%) among trauma critical care nurses (n = 49). Findings support the content validation and inter-rater reliability of the adapted French-Canadian version of the SSA tool in moderate-severe TBI and cervical SCI patients. Sensitivity was acceptable in both groups, but the specificity was lower, especially in moderate-severe TBI patients. Further validation of the adapted French-Canadian version of the SSA tool is needed in neurotrauma patients to confirm these results and to ensure safe dysphagia screening while avoiding oral feeding deferrals.

Level of implementation of pain management and early mobilization strategies to prevent delirium in geriatric trauma patients: A mixed-methods study

BACKGROUND

Pain management and early mobilization strategies are recommended in clinical practice guidelines for the prevention of delirium in older adults. However, available data on the implementation of these strategies in trauma are limited.

AIMS

To describe the use of pain management and early mobilization strategies in older adults at a level I trauma center, as well as the facilitators and barriers to their implementation.

METHODS

A convergent mixed methods study was used. Quantitative data were collected from sixty medical records. Qualitative data was collected through a focus group with healthcare providers to explore their perspectives regarding the use of the target practices and on barriers and facilitators to their implementation. Descriptive statistics were calculated, and a thematic analysis using an inductive and deductive interpretative descriptive approach was undertaken.

RESULTS

A question on the presence/absence of pain was the most frequently documented pain assessment method. Pain assessment was poorly documented. Frequencies of non-opioid and opioid administrations were similar, but non-pharmacological strategies were not widely used. The first mobilization was performed quickly and was most commonly to a chair. The focus group discussion confirmed many of the data collected in the medical records. Barriers to implementing the targeted strategies were primarily related to organizational context and facilitation processes.

CONCLUSIONS

Areas for improvement were identified including pain assessment, the use of non-pharmacological pain management strategies and ambulation as a mobilization strategy. Our findings will serve as a starting point for optimizing and adapting practices for geriatric trauma patients and evaluating their impact.

Interrater Agreement between Bedside and Video Raters Using the CPOT-Neuro for Pain Assessment in Critically Ill Patients with a Brain Injury

This study aimed to examine the interrater agreement of Critical-Care Pain Observation Tool-Neuro (CPOT-Neuro) scores as a newly developed tool for pain assessment in patients with critical illness and brain injury between raters using two methods of rating (bedside versus video) during standard care procedures (i.e., non-invasive blood pressure and turning). The bedside raters were research staff, and the two video raters had different backgrounds (health and non-health disciplines). Raters received standardized 45 min training by the principal investigator. Video recordings of 56 patient participants with a brain injury at different levels of consciousness were included. Interrater agreement was supported with an Intraclass Correlation Coefficient (ICC) > 0.65 for all pairs of raters and for each procedure. Interrater agreement was highest during turning in the conscious group, with ICCs ranging from 0.79 to 0.90. The use of video recordings was challenging for the observation of some behaviors (i.e., tearing, face flushing), which were influenced by factors such as lighting and the angle of the camera. Ventilator alarms were also challenging to distinguish from other sources for the video rater from a non-health discipline. Following standardized training, video technology was useful in achieving an acceptable interrater agreement of CPOT-Neuro scores between bedside and video raters for research purposes.

Relationship Between Pain and Delirium in Critically Ill Adults

OBJECTIVES

Although opioids are frequently used to treat pain, and are an important risk for ICU delirium, the association between ICU pain itself and delirium remains unclear. We sought to evaluate the relationship between ICU pain and delirium.

DESIGN

Prospective cohort study.

SETTING

A 32-bed academic medical-surgical ICU.

PATIENTS

Critically ill adults (n = 4,064) admitted greater than or equal to 24 hours without a condition hampering delirium assessment.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Daily mental status was classified as arousable without delirium, delirium, or unarousable. Pain was assessed six times daily in arousable patients using a 0-10 Numeric Rating Scale (NRS) or the Critical Care Pain Observation Tool (CPOT); daily peak pain score was categorized as no (NRS = 0/CPOT = 0), mild (NRS = 1-3/CPOT = 1-2), moderate (NRS = 4-6/CPOT = 3-4), or severe (NRS = 7-10/CPOT = 5-8) pain. To address missingness, a Multiple Imputation by Chained Equations approach that used available daily pain severity and 19 pain predictors was used to generate 25 complete datasets. Using a first-order Markov model with a multinomial logistic regression analysis, that controlled for 11 baseline/daily delirium risk factors and considered the competing risks of unarousability and ICU discharge/death, the association between peak daily pain and next-day delirium in each complete dataset was evaluated.

RESULTS

Among 14,013 ICU days (contributed by 4,064 adults), delirium occurred on 2,749 (19.6%). After pain severity imputation on 1,818 ICU days, mild, moderate, and severe pain were detected on 2,712 (34.1%), 1,682 (21.1%), and 894 (11.2%) of the no-delirium days, respectively, and 992 (36.1%), 513 (18.6%), and 27 (10.1%) of delirium days (p = 0.01). The presence of any pain (mild, moderate, or severe) was not associated with a transition from awake without delirium to delirium (aOR 0.96; 95% CI, 0.76-1.21). This association was similar when days with only mild, moderate, or severe pain were considered. All results were stable after controlling for daily opioid dose.

CONCLUSIONS

After controlling for multiple delirium risk factors, including daily opioid use, pain may not be a risk factor for delirium in the ICU. Future prospective research is required.

International Analgesia and Sedation Weaning and Withdrawal Practices in Critically Ill Adults: The Adult Iatrogenic Withdrawal Study in the ICU

OBJECTIVES

Iatrogenic withdrawal syndrome (IWS) associated with opioid and sedative use for medical purposes has a reported high prevalence and associated morbidity. This study aimed to determine the prevalence, utilization, and characteristics of opioid and sedative weaning and IWS policies/protocols in the adult ICU population.

DESIGN

International, multicenter, observational, point prevalence study.

SETTING

Adult ICUs.

PATIENTS

All patients aged 18 years and older in the ICU on the date of data collection who received parenteral opioids or sedatives in the previous 24 hours.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

ICUs selected 1 day for data collection between June 1 and September 30, 2021. Patient demographic data, opioid and sedative medication use, and weaning and IWS assessment data were collected for the previous 24 hours. The primary outcome was the proportion of patients weaned from opioids and sedatives using an institutional policy/protocol on the data collection day. There were 2,402 patients in 229 ICUs from 11 countries screened for opioid and sedative use; 1,506 (63%) patients received parenteral opioids, and/or sedatives in the previous 24 hours. There were 90 (39%) ICUs with a weaning policy/protocol which was used in 176 (12%) patients, and 23 (10%) ICUs with an IWS policy/protocol which was used in 9 (0.6%) patients. The weaning policy/protocol for 47 (52%) ICUs did not define when to initiate weaning, and the policy/protocol for 24 (27%) ICUs did not specify the degree of weaning. A weaning policy/protocol was used in 34% (176/521) and IWS policy/protocol in 9% (9/97) of patients admitted to an ICU with such a policy/protocol. Among 485 patients eligible for weaning policy/protocol utilization based on duration of opioid/sedative use initiation criterion within individual ICU policies/protocols 176 (36%) had it used, and among 54 patients on opioids and/or sedatives ≥ 72 hours, 9 (17%) had an IWS policy/protocol used by the data collection day.

CONCLUSIONS

This international observational study found that a small proportion of ICUs use policies/protocols for opioid and sedative weaning or IWS, and even when these policies/protocols are in place, they are implemented in a small percentage of patients.

Preliminary clinical testing to inform development of the Critical Care Pain Observation Tool for Families (CPOT-Fam)

Introduction

Many patients in the intensive care unit (ICU) cannot communicate. For these patients, family caregivers (family members/close friends) could assist in pain assessment. We previously adapted the Critical Care Pain Observation Tool (CPOT) for family caregiver use (CPOT-Fam). In this study, we conducted preliminary clinical evaluation of the CPOT-Fam to inform further tool development.

Methods

For preliminary testing, we collected (1) pain assessments of patients in the ICU from family caregivers (CPOT-Fam) and nurses (CPOT) and determined the degree of agreement (kappa coefficient, κ) and (2) collected openended feedback on the CPOT-Fam from family caregivers. For refinement, we used preliminary testing data to refine the CPOT-Fam with a multidisciplinary working group.

Results

We assessed agreement between family caregiver and nurse pain scores for 29 patients. Binary agreement (κ) between CPOT-Fam and CPOT item scores (scores ≥2 considered indicative of significant pain) was fair, κ = 0.43 (95% confidence interval [CI] 0.18-0.69). Agreement was highest for the CPOT-Fam items ventilator compliance/vocalization (weighted κ = 0.48, 95% CI 0.15-0.80) and lowest for muscle tension (weighted κ = 0.10, 95% [CI] -0.17 to 0.20). Most participants (n = 19; 69.0%) reported a very positive experience using the CPOT-Fam, describing it as "good" and "easy-to-use/clear/straightforward." We iteratively refined the CPOT-Fam over five cycles using the data collected until no further revisions were suggested.

Conclusion

Our preliminary clinical testing suggests that family involvement in pain assessment in the ICU is well perceived. The CPOT-Fam has been further refined and is now ready for clinical pilot testing to determine its feasibility and acceptability.

Symptom Assessment for Mechanically Ventilated Patients: Principles and Priorities: An Official American Thoracic Society Workshop Report

Mechanically ventilated patients experience many adverse symptoms, such as anxiety, thirst, and dyspnea. However, these common symptoms are not included in practice guideline recommendations for routine assessment of mechanically ventilated patients. An American Thoracic Society-sponsored workshop with researchers and clinicians with expertise in critical care and symptom management was convened for a discussion of symptom assessment in mechanically ventilated patients. Members included nurses, physicians, a respiratory therapist, a speech-language pathologist, a critical care pharmacist, and a former intensive care unit patient. This report summarizes existing evidence and consensus among workshop participants regarding 1) symptoms that should be considered for routine assessment of adult patients receiving mechanical ventilation; 2) key symptom assessment principles; 3) strategies that support symptom assessment in nonvocal patients; and 4) areas for future clinical practice development and research. Systematic patient-centered assessment of multiple symptoms has great potential to minimize patient distress and improve the patient experience. A culture shift is necessary to promote ongoing holistic symptom assessment with valid and reliable instruments. This report represents our workgroup consensus on symptom assessment for mechanically ventilated patients. Future work should address how holistic, patient-centered symptom assessment can be embedded into clinical practice.

The Validity of Vital Signs for Pain Assessment in critically Ill Adults: A Narrative Review

OBJECTIVES

Pain assessment in the intensive care unit (ICU) is challenging because many patients are unable to self-report or exhibit pain-related behaviors. In such situations, vital signs (VS) through continuous monitoring are alternative cues for pain assessment. This review aimed to describe the reliability and validity of VS for ICU pain assessment.

DESIGN

Narrative review of the literature.

DATA SOURCES

Medline, Embase, CINAHL, Cochrane.

REVIEW/ANALYSIS METHODS

A narrative review was conducted with a comprehensive search in four databases. Search terms included VS, pain assessment, and ICU.

RESULTS

Out of 1,359 results, 30 studies from 17 countries were included. Heart rate, blood pressure, and respiratory rate were most used for ICU pain assessment. Assessments were performed at rest before procedures, during nociceptive and non-nociceptive procedures, and after procedures. Increases in respiratory rate were clinically significant by more than 25% during nociceptive procedures (e.g., endotracheal suctioning, turning) compared with rest/pre-procedures in five studies. Correlations of VS with self-reported pain (reference standard measure) and behavioral pain scores (alternative measure) were absent or weak.

CONCLUSIONS

VS are not valid indicators for ICU pain assessment. Increases of respiratory rate may be a cue for the detection of pain. However, fluctuations in respiratory rate can be influenced by opioids or controlled ventilation mode. Our results dissuade the use of VS for pain assessment because of the lack of association with ICU pain reference standards. Other physiologic measures of pain in critically ill adults should be explored.

Prediction of acute postoperative pain based on intraoperative nociception level (NOL) index values: the impact of machine learning-based analysis

The relationship between intraoperative nociception and acute postoperative pain is still not well established. The nociception level (NOL) Index (Medasense, Ramat Gan, Israel) uses a multiparametric approach to provide a 0-100 nociception score. The objective of the ancillary analysis of the NOLGYN study was to evaluate the ability of a machine-learning aglorithm to predict moderate to severe acute postoperative pain based on intraoperative NOL values. Our study uses the data from the NOLGYN study, a randomized controlled trial that evaluated the impact of NOL-guided intraoperative administration of fentanyl on overall fentanyl consumption compared to standard of care. Seventy patients (ASA class I-III, aged 18-75 years) scheduled for gynecological laparoscopic surgery were enrolled. Variables included baseline demographics, NOL reaction to incision or intubation, median NOL during surgery, NOL time-weighted average (TWA) above or under manufacturers' recommended thresholds (10-25), and percentage of surgical time spent with NOL > 25 or < 10. We evaluated different machine learning algorithms to predict postoperative pain. Performance was assessed using cross-validated area under the ROC curve (CV-AUC). Of the 66 patients analyzed, 42 (63.6%) experienced moderate to severe pain. NOL post-intubation (42.8 (31.8-50.6) vs. 34.8 (25.6-41.3), p = 0.05), median NOL during surgery (13 (11-15) vs. 11 (8-13), p = 0.027), percentage of surgical time spent with NOL > 25 (23% (18-18) vs. 20% (15-24), p = 0.036), NOL TWA < 10 (2.54 (2.1-3.0) vs. 2.86 (2.48-3.62), p = 0.044) and percentage of surgical time spent with NOL < 10 (41% (36-47) vs. 47% (40-55), p = 0.022) were associated with moderate to severe PACU pain. Corresponding ROC AUC for the prediction of moderate to severe PACU pain were 0.65 [0.51-0.79], 0.66 [0.52-0.81], 0.66 [0.52-0.79], 0.65 [0.51-0.79] and 0.67 [0.53-0.81]. Penalized logistic regression achieved the best performance with a 0.753 (0.718-0.788) CV-AUC. Our results, even if limited by the small number of patients, suggest that acute postoperative pain is better predicted by a multivariate machine-learning algorithm rather than individual intraoperative nociception variables. Further larger multicentric trials are highly recommended to better understand the relationship between intraoperative nociception and acute postoperative pain.Trial registration Registered on ClinicalTrials.gov in October 2018 (NCT03776838).

Validation of the Critical-Care Pain Observation Tool (CPOT) in pediatric patients undergoing orthopedic surgery

Background

Postoperative pain cannot be measured accurately among many children with intellectual and developmental disabilities, resulting in underrecognition or delay in recognition of pain. The Critical-Care Pain Observation Tool (CPOT) is a pain assessment tool that has been widely validated in critically ill and postoperative adults.

Aims

The objective of this study was to validate the CPOT for use with pediatric patients able to self-report and undergoing posterior spinal fusion surgery.

Methods

Twenty-four patients (10-18 years old) scheduled to undergo surgery were consented to this repeated-measure, within-subject study. To examine discriminative and criterion validation, CPOT scores and patients' self-reports of pain intensity were collected prospectively by a bedside rater before, during, and after a nonnociceptive and nociceptive procedure on the day following surgery. Patients' behavioral reactions were video recorded at the bedside and retrospectively viewed by two independent video raters to examine interrater and intrarater reliability of CPOT scores.

Results

Discriminative validation was supported with higher CPOT scores during the nociceptive procedure than during the nonnociceptive procedure. Criterion validation was supported with a moderate positive correlation between the CPOT scores and the patients' self-reported pain intensity during the nociceptive procedure. A CPOT cutoff score of ≥2 was associated with the maximum sensitivity (61.3%) and specificity (94.1%). Reliability analyses revealed poor to moderate agreement between bedside and video raters and moderate to excellent consistency within video raters.

Conclusions

These findings suggest that the CPOT may be a valid tool to detect pain in pediatric patients in the acute postoperative inpatient care unit after posterior spinal fusion.

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.

Strategies to improve the quality of nurse triage in emergency departments: A realist review protocol

AIM

The purpose of this realist review was to assess what works, for whom and in what context, regarding strategies that influence nurses' behaviour to improve triage quality in emergency departments (ED).

DESIGN

Realist review protocol.

METHODS

This protocol follows the PRISMA-P statement and will include any type of study on strategies to improve the triage process in the ED (using recognized and validated triage scales). The included studies were examined for scientific quality using the Mixed Methods Appraisal Tool. The framework for this realist review is based on the Behaviour Change Wheel (BCW) and the context-mechanism-outcome (CMO) models.

DISCUSSION

Nurses and ED decision makers will be informed on the evidence regarding strategies to improve the quality of triage and the factors required to maximize their effectiveness. Research gaps may also be identified to guide future research projects on the adoption of best practices in ED nursing triage.

French-Canadian Translation and Cultural Adaptation of the Clinical Opiate Withdrawal Scale: The COWS-FC

OBJECTIVE

The main objective of the present study was to develop a French-Canadian translation and adaptation of the COWS (i.e., the COWS-FC) for the assessment of opioid withdrawal symptoms in clinical and research settings.

METHODS

The French-Canadian translation and cultural adaptation of the COWS was performed following guidelines for the translation and cross-cultural adaptation of self-report measures. The steps consisted of (1) initial translation from English to French, (2) synthesis of the translation, (3) back-translation from French to English, (4) expert committee meeting, (5) test of the prefinal version among healthcare professionals and (6) review of final version by the expert committee. The expert committee considered four major areas where the French-Canadian version should achieve equivalence with the original English-version of the COWS. These areas were (1) semantic equivalence; (2) idiomatic equivalence; (3) experiential equivalence and (4) conceptual equivalence.

RESULTS

Rigorous steps based on the guidelines for the translation and cultural adaptation of assessment tools were followed, which led to a semantically equivalent version of the COWS. After a pretest among healthcare professionals, members from the expert committee agreed upon slight modifications to the French-Canadian version of the COWS to yield a final COWS-FC version.

CONCLUSIONS

A French-Canadian translation and adaptation of the COWS (i.e., the COWS-FC) was developed. The COWS-FC could be used for the assessment of opioid withdrawal symptoms in clinical and research settings.

Study protocol: development and pilot testing of the Critical Care Pain Observation Tool for families (CPOT-Fam)

Background

Patients in the intensive care unit (ICU) often have limited ability to communicate making it more difficult to identify and effectively treat their pain. Family caregivers or close friends of critically ill patients may be able to identify signs of pain before the clinical care team and could potentially assist in routine pain assessments. This study will adapt the Critical Care Pain Observation Tool (CPOT) for use by family members to create the CPOT-Fam and compare family CPOT-Fam assessments with nurse-provided CPOT assessments for a given patient.

Methods

This study will be executed in two phases:

1) Development of the CPOT-Fam — A working group of patient partners, ICU clinicians, and researchers will adapt the CPOT for use by family caregivers (creating the CPOT-Fam) and produce an accompanying educational module to deliver information on pain and how to use the tool. The CPOT-Fam will undergo preclinical testing with participants (i.e., members of the public and family caregivers of critically ill adults), who will complete the educational module and provide CPOT-Fam scores on sample cases. Feedback on the CPOT-Fam will be collected.

2) Pilot testing the CPOT — Fam family caregivers of critically ill adults will complete the educational module and provide information on the following: (1) demographics, (2) anxiety, (3) caregiving self-efficacy, and (4) satisfaction with care in the ICU. Family caregivers will then provide a proxy assessment of their critically ill loved one’s pain through the CPOT-Fam and also provide a subjective (i.e., questionnaire-based including open-ended responses) account of their loved one’s pain status. A comparison (i.e., agreement) will be made between family caregiver provided CPOT-Fam scores and ICU nurse-provided CPOT scores (collected from the provincial health information system), calculated independently and blinded to one another. Feasibility and acceptability of the CPOT-Fam will be determined.

Discussion

The results of this work will produce a family caregiver CPOT (i.e., CPOT-Fam), determine feasibility and acceptability of the CPOT-Fam, and compare pain assessments conducted by family caregivers and ICU nurses. The results will inform whether a larger study to determine a role for family caregivers in ICU pain assessment using the CPOT-Fam is warranted.

Acceptability and Feasibility of a Patient-Oriented Music Intervention to Reduce Pain in the Intensive Care: Protocol for a Randomized Crossover Pilot Trial (Preprint)

BACKGROUND

Many patients experience pain in the intensive care unit (ICU) despite receiving pain medication. Research has shown that music can help reduce pain. Music interventions studied so far have not used music streaming to generate playlists based on patient preferences while incorporating recommended tempo and duration. Previous research has focused on postoperative ICU patients able to self-report, which is underrepresentative of the ICU population that might benefit from a music intervention for pain management. We developed a new patient-oriented music intervention (POMI) that incorporates features based on theoretical, empirical, and experiential data intended to be used in the ICU. Such a music intervention should consider the expertise of ICU patients, family members, and nursing staff, as well as the practicality of the intervention when used in practice.

OBJECTIVE

The primary objectives of this study are to (1) evaluate the acceptability and feasibility of the POMI to reduce pain in ICU patients and (2) evaluate the feasibility of conducting a crossover pilot randomized controlled trial (RCT) for intervention testing in the ICU. A secondary objective is to examine the preliminary efficacy of the POMI to reduce pain in ICU patients.

METHODS

A single-blind 2×2 crossover pilot RCT will be conducted. Patients will undergo 1 sequence of 2 interventions: the POMI which delivers music based on patients' preferences via headphones or music pillow for 20-30 minutes and the control intervention (headphones or pillow without music). The sequence of the interventions will be inverted with a 4-hour washout period. Timing of the interventions will be before a planned bed turning procedure. Each patient will undergo 1 session of music. Twenty-four patients will be recruited. Patients able to self-report (n=12), family members of patients unable to self-report (n=12), and nursing staff (n=12) involved in the bed turning procedure will be invited to complete a short questionnaire on the POMI acceptability. Data will be collected on the feasibility of the intervention delivery (ie, time spent creating a playlist, any issue related to headphones/pillow or music delivery, environmental noises, and intervention interruptions) and research methods (ie, number of patients screened, recruited, randomized, and included in the analysis). Pain scores will be obtained before and after intervention delivery.

RESULTS

Recruitment and data collection began in March 2022. As of July 5, 2022, in total, 22 patients, 12 family members, and 11 nurses were recruited.

CONCLUSIONS

Methodological limitations and strengths are discussed. Study limitations include the lack of blinding for patients able to self-report. Strengths include collecting data from various sources, getting a comprehensive evaluation of the intervention, and using a crossover pilot RCT design, where participants act as their own control, thus reducing confounding factors.

Identification of the intraoperative antinociceptive effect of intravenous fentanyl using the Nociception Level (NOL) index versus clinical parameters in patients undergoing gynecological laparoscopic surgery: A secondary analysis of the NOLGYN study

BACKGROUND

While we typically assess nociception balance during general anaesthesia through clinical parameters such as heart rate (HR) and mean arterial pressure (MAP) variation, these parameters are not specific to nociception.

OBJECTIVE

We hypothesized that using the Nociception Level (NOL) index to assess the analgesic effect of a fentanyl bolus would be superior to standard clinical parameters.

DESIGN

Ancillary study of the NOLGYN study, a randomized controlled trial comparing intraoperative NOL-guided administration of fentanyl (NOL group) versus standardized care (SC group).

SETTING

University hospital in Montréal, Canada between November 2018, and December 2019.

PATIENTS

Women undergoing gynecological laparoscopic surgery.

INTERVENTION

In our evaluation of intraoperative nociception, we analyzed the analgesic effect of fentanyl using three parameters: MAP, HR, and the Nociception Level (NOL) index. All fentanyl injection events were extracted from the database.

MAIN OUTCOME MEASURE

The primary endpoint was the difference between values before and after each injection.

RESULTS

The median of the NOL index before fentanyl injection was 30.5 (IQR 19.4 to 40.7) versus 18.9 (IQR 11.5 to 27.4) after (P < 0.001). The median of MAP was 106.4 mmHg (IQR 99.9 to 113.4) before injection versus 103.2 mmHg (IQR 97.5 to 110.7) after (P < 0.001). The median of HR before injection was 74.2 (IQR 64.2 to 83.8) versus 72.4 (IQR 63.4 to 81.3) after (P < 0.001).

CONCLUSIONS

The NOL index, HR, and MAP all statistically discriminated the analgesic effect of fentanyl but only the NOL index proved clinically relevant to identify the analgesic effect of one fentanyl injection.

Psychological distress, depression symptoms and fatigue among Quebec nursing staff during the COVID-19 pandemic: A cross-sectional study

Aim

To describe the state of health of Quebec nursing staff during the pandemic according to their exposure to COVID‐19, work‐related characteristics and sociodemographic factors (gender, generational age group). State of health was captured essentially by assessing psychological distress, depression symptoms and fatigue.

Design and methods

A large‐scale cross‐sectional study was conducted with 1,708 nurses and licenced practical nurses in Quebec (87% women, mean age of 41 ± 11 years). The survey included several questionnaires and validated health‐related scales (psychological distress, depression symptoms and fatigue). The STROBE guidelines were followed in reporting the study's findings.

Results

Results showed that the prevalence of psychological distress and depression symptoms was moderate to severe. Women, generation Xers and Yers, nurses who cared for COVID‐19 patients and those with a colleague who was infected with COVID‐19 at work scored higher for fatigue, psychological distress and depression.

Exploration of a Multi-Parameter Technology for Pain Assessment in Postoperative Patients After Cardiac Surgery in the Intensive Care Unit: The Nociception Level Index (NOL)TM

Introduction

The aim of this study was to explore the use of a multi-parameter technology, the Nociception Level (NOL) index (Medasense Biometrics Ltd, Ramat Gan, Israel), for pain assessment in postoperative awake patients after cardiac surgery during non-nociceptive and nociceptive procedures in the intensive care unit (ICU).

Materials and Methods

A prospective cohort repeated-measures design was used. Patients were included if they were in the ICU after undergoing cardiac surgery and if they could self-report their pain. A non-invasive probe was placed on the patient’s finger for the continuous monitoring of the NOL index. Patients’ self-reports of pain and anxiety (0–10 Numeric Rating Scale or NRS), and behavioral scores with the Critical-Care Pain Observation Tool (CPOT) were obtained before and during a non-nociceptive procedure (ie, non-invasive blood pressure [NIBP] using cuff inflation), and before, during and after a nociceptive procedure (ie, chest tube removal [CTR]) for a total of five time points. Non-parametric tests were used to compare scores at different time points, and receiver operating characteristic curve analysis was performed.

Results

Fifty-four patients were included in the analysis. The NOL index, pain and anxiety scores were significantly higher during CTR compared to rest and NIBP (p < 0.001). During CTR, the NOL was associated with self-reported pain intensity and unpleasantness but not with anxiety and CPOT scores. The NOL showed a modest performance in detecting pain (NRS ≥1 and ≥5) in this sample with sensitivity and specificity ranging from 61% to 85%.

Conclusion

The NOL index was able to discriminate between a non-nociceptive and a nociceptive procedure and was associated with self-reported pain. Further validation testing of the NOL is necessary in a heterogeneous sample of ICU patients.

Description of the validity of the Analgesia Nociception Index (ANI) and Nociception Level Index (NOL) for nociception assessment in anesthetized patients undergoing surgery: a systematized review

Maintaining optimum analgesia in anesthetized patients is challenging due to the inability to self-report pain or exhibit pain-related behaviours. The Analgesia Nociception Index (ANI) (based on heart rate variability [HRV]) and the Nociception Level Index (NOL) (based on HRV, photoplethysmography, skin conductance, and temperature) both include HRV and provide continuous index monitoring for nociception assessment. The research question was: "What are the validation strategies of the NOL and ANI for nociception assessment in anesthetized patients?". The objectives were to describe and analyze the validation strategies and results. A systematized review was conducted using a comprehensive search with keywords under three concepts (nociception/pain, ANI/NOL, and validity) in four databases. A quality assessment using an adapted GRADE approach for measurement tools, and a risk of bias assessment using QUADAS-2 tool were performed by two reviewers. Out of 525 results, 15 validation studies were included. Strategies included hypothesis testing, discriminative, and criterion validation. Significant changes in ANI/NOL values were found in response to nociceptive stimuli at different opioid concentrations (hypothesis testing). Higher ANI/NOL values were observed during nociceptive stimuli (discriminative). AUCs ranging from 0.83 to 0.99 were obtained to detect nociceptive stimuli (criterion). Both technologies performed superiorly in detecting nociceptive stimuli compared to individual monitoring of HR and blood pressure. Although the aforementioned validation strategies are deemed appropriate, in the absence of a gold standard, criterion validation findings should be interpreted with caution. Moreover, reliability could be examined using test-retest with consistent ANI/NOL values during a stable time-interval.

Influence of caring for COVID-19 patients on nurse's turnover, work satisfaction and quality of care

Aim

This study aims to examine, through the lens of the Job Demands‐Resources model, the influence of caring for COVID‐19 patients on nurse's perception of chronic fatigue, quality of care, satisfaction at work and intention to leave their organisation and the profession.

Background

Studies have examined how fear of COVID‐19 contributes to the mental, physical and work adjustment among nurses. To date, few studies have been conducted examining how caring for patients with COVID‐19 contributes to work outcomes among nurses.

Methods

This is a cross‐sectional survey involving 1705 frontline nurses and licensed practical nurses in Quebec, Canada. From these, 782 reported caring for COVID‐19 patients.

Results

High chronic fatigue, poor quality of care, lower work satisfaction and higher intention to leave their organisation were found for nurses caring for COVID‐19 patients. Poorly prepared and overwhelmed nurses showed higher turnover intention than those well prepared and in control.

Conclusions

There is an urgent need to provide support to nurses during the pandemic, with a long‐term strategy to increase their retention.

Implications for Nursing Management

Nurse administrators play an important role in supporting their nurses during a pandemic in the form of education, training and policy development to positively impact quality of care and retention.

Determinants of pain assessment documentation in intensive care units

PURPOSE

The underassessment of pain is a major barrier to effective pain management, and the lack of pain assessment documentation has been associated with negative patient outcomes. This study aimed to 1) describe the contextual factors related to pain assessment and management in five Québec intensive care units (ICUs); 2) describe their pain assessment documentation practices; and 3) identify sociodemographic and clinical determinants related to pain assessment documentation.

METHODS

A descriptive-correlational retrospective design was used. Sociodemographic data (i.e., age, sex), clinical data (i.e., diagnosis, mechanical ventilation, level of consciousness, severity of illness, opioids, sedatives), and pain assessments were extracted from 345 medical charts of ICU admissions from five teaching hospitals between 2017 and 2019. Descriptive statistics and multiple linear regression were performed.

RESULTS

All sites reported using the 0-10 numeric rating scale, but the implementation of a behavioural pain scale was variable across sites. A median of three documented pain assessments were performed per 24 hr, which is below the minimal recommendation of eight to 12 pain assessments per 24 hr. Overall, pain assessment was present in 70% of charts, but only 20% of opioid doses were followed by documented pain reassessment within one hour post-administration. Higher level of consciousness (β = 0.37), using only breakthrough doses (β = 0.24), and lower opioid doses (β = -0.21) were significant determinants of pain assessment documentation (adjusted R2 = 0.25).

CONCLUSION

Pain assessment documentation is suboptimal in ICUs, especially for patients unable to self-report or those receiving higher opioid doses. Study findings highlight the need to implement tools to optimize pain assessment and documentation.

Strategies for the Prevention and Treatment of Iatrogenic Withdrawal from Opioids and Benzodiazepines in Critically Ill Neonates, Children and Adults: A Systematic Review of Clinical Studies

BACKGROUND

Critically ill patients are at high risk of iatrogenic withdrawal syndrome (IWS), due to exposure to high doses or prolonged periods of opioids and benzodiazepines.

PURPOSE

To examine pharmacological management strategies designed to prevent and/or treat IWS from opioids and/or benzodiazepines in critically ill neonates, children and adults.

METHODS

We included non-randomised studies of interventions (NRSI) and randomised controlled trials (RCTs), reporting on interventions to prevent or manage IWS in critically ill neonatal, paediatric and adult patients. Database searching included: PubMed, CINAHL, Embase, Cochrane databases, TRIP, CMA Infobase and NICE evidence. Additional grey literature was examined. Study selection and data extraction were performed in duplicate. Data collected included: population, definition of opioid, benzodiazepine or mixed IWS, its assessment and management (drug or strategy, route of administration, dosage and titration), previous drug exposures and outcomes measures. Methodological quality assessment was performed by two independent reviewers using the Cochrane risk of bias tool for RCTs and the ROBINS-I tool for NRSI. A qualitative synthesis of the results is provided. For the subset of studies evaluating multifaceted protocolised care, we meta-analysed results for 4 outcomes and examined the quality of evidence using GRADE post hoc.

RESULTS

Thirteen studies were eligible, including 10 NRSI and 3 RCTs; 11 of these included neonatal and paediatric patients exclusively. Eight studies evaluated multifaceted protocolised interventions, while 5 evaluated individual components of IWS management (e.g. clonidine or methadone at varying dosages, routes of administration and duration of tapering). IWS was measured using an appropriate tool in 6 studies. Ten studies reported upon occurrence of IWS, showing significant reductions (n = 4) or no differences (n = 6). Interventions failed to impact duration of mechanical ventilation, ICU length of stay, and adverse effects. Impact on opioid and/or benzodiazepine total doses and duration showed no differences in 4 studies, while 3 showed opioid and benzodiazepine cumulative doses were significantly reduced by 20-35% and 32-66%, and treatment durations by 1.5-11 and 19 days, respectively. Variable effects on intervention drug exposures were found. Weaning durations were reduced by 6-12 days (n = 4) for opioids and/or methadone and by 13 days (n = 1) for benzodiazepines. In contrast, two studies using interventions centred on transition to enteral routes or longer tapering durations found significant increases in intervention drug exposures. Interventions had overall non-significant effects on additional drug requirements (except for one study). Included studies were at high risk of bias, relating to selection, detection and reporting bias.

CONCLUSION

Interventions for IWS management fail to impact duration of mechanical ventilation or ICU length of stay, while effect on occurrence of IWS and drug exposures is inconsistent. Heterogeneity in the interventions used and methodological issues, including inappropriate and/or subjective identification of IWS and bias due to study design, limited the conclusions.

Translation of the Fear of COVID-19 Scale into French-Canadian and English-Canadian and Validation in the Nursing Staff of Quebec

Introduction: During the COVID-19 pandemic, Quebec has been one of the most affected provinces in Canada. Rising fear of COVID-19 is inevitable among healthcare workers, and a new scale was developed to measure this type of fear, the Fear of COVID-19 Scale (FCV-19S). Aims: To translate the FCV-19S into French-Canadian and English-Canadian, and to validate both versions in the nursing staff from Quebec. Methods: A cross-sectional online survey was sent to approximately 15 000 nursing staff including nurses and licensed practical nurses among those who had consented to their respective Order to be contacted for research. The forward-backward method was used to translate the FCV-19S into French-Canadian and English-Canadian. Both versions along with stress and work-related questionnaires, were used to establish validity. Results: A total of 1708 nursing staff, with a majority of women, completed the survey (1517 and 191 completed the French-Canadian and English-Canadian versions). A unidimensional scale was confirmed for both versions with Cronbach alphas of 0.90 and 0.88. Discriminative values showed higher fear levels in women, and in generation X (40-56 years old). Higher fear levels were also found in nursing staff working in long-term care facilities, provided care to COVID-19 patients who died, and those who felt less prepared to provide safe care. Convergent associations were found between fear levels, stress, work satisfaction, and turnover intention. Discussion and conclusion: A rigorous approach was used to translate the fear of COVID-19 scale into French-Canadian and English-Canadian. Both Canadian versions of the FCV-19S supported a valid unidimensional scale in Quebec nursing staff.
