Face and content validity of variables associated with the difficult-to-sedate child in the paediatric intensive care unit: A survey of paediatric critical care clinicians

Initial Psychometric Testing of a Pain Quality Pictogram Tool Among Hmong Limited English Proficient and Bilingual Community Members and Healthcare Practitioners

PURPOSE

To assess the matching and content validity of a pain quality pictogram tool with a Hmong community.

DESIGN

A Qualtrics survey was administered to two groups of participants.

METHODS

Sixty Hmong participants (n = 49 limited English proficiency and bilingual Hmong community members in group 1; n = 11 bilingual Hmong healthcare practitioners in group 2) participated in this study. Hmong community members in group 1 were asked to identify the pain pictogram that best matched a pre-recorded Hmong pain quality phrase. The practitioners in group 2 were asked to evaluate how well each pain pictogram represented the pre-recorded Hmong pain quality phrase it intended to measure. To assess the matching, we assessed agreement between the pain concept in the phrase and the pictogram intended to represent it, using group 1. A content validity index (CVI) was calculated to assess the content validity of the tool using group 2.

RESULTS

Among the community participants, 8 of the 15 pictograms were matched with the intended phrase almost perfectly, and 3 were matched by a substantial majority. There were no differences in matching by patient gender and language proficiency. Among practitioners, 11 of 15 pain pictograms met the CVI threshold of 0.70 for all three dimensions (i.e., representativeness, relevance, and comprehension).

CONCLUSION

Findings support including most of the pain pictograms in the tool but suggest specific areas for improvement.

CLINICAL IMPLICATIONS

Findings provide insights for redesigning the selected pain pictogram tool to be used in clinical settings with LEP Hmong patients.

Enteral Pentobarbital in the Difficult to Sedate Critically Ill Children

OBJECTIVE

Difficult analgosedation is common and challenging in the pediatric intensive care unit (PICU). It is important to study alternative and supplemental sedatives for when the first-line agents become -insufficient.

METHODS

In this retrospective chart-review study, we report our center's experience in using intermittent doses of enteral pentobarbital as an adjunct sedative in 13 difficult to sedate critically ill and mechanically ventilated children. We compare the average sedation score and cumulative doses of other -sedatives (opioids, benzodiazepines and alpha-2 agonists) in the 24 hours before and 24 hours after enteral -pentobarbital initiation.

RESULTS

The addition of enteral pentobarbital was associated with lower State Behavioral State (SBS) scores in 8 out of the 13 patients and on average smaller doses of opioids (decreased by 11%), benzodiazepines (BZD) (decreased by 5%) and alpha-agonists (decreased by 20%). No adverse effects were noted attributable to pentobarbital administration.

CONCLUSION

Enteral pentobarbital seems to be safe and effective agent in the difficult to sedate critically ill child.

Validation of CHERG'S Verbal Autopsy-Social Autopsy (VASA) tool for ascertaining determinants and causes of under-five child mortality in Pakistan

The majority (40%) of the world's under-five mortality burden is concentrated in nations like Nigeria (16.5%), India (16%), Pakistan (8%), and the Democratic Republic of the Congo (6%), where an undetermined number of under-five deaths go unrecorded. In low-resource settings throughout the world, the Verbal Autopsy-Social Autopsy (VASA) technique may assist assess under-five mortality estimates, assigning medical and social causes of death, and identifying relevant determinants. Uncertainty regarding missing data in high-burden nations like Pakistan necessitates a valid and reliable VASA instrument. This is the first study to validate Child Health Epidemiology Reference Group-CHERG's VASA tool globally. In Pakistan, data from such a valid and reliable tool is vital for policy. This paper reports on the VASA tool in Karachi, Pakistan. Validity and reliability of the CHERG VASA tool were tested using face, content, discriminant validation, and reliability tests on one hundred randomly selected mothers who had recently experienced an under-five child death event. Data were computed on SPSS (version-21) and R software. Testing revealed high Item-content Validity Index (I-CVI) (>81.43%); high Cronbach's Alpha (0.843); the accuracy of between 75-100% of the discriminants classifying births to live and stillbirths; and I-CVI (>82.07% and 88.98% respectively) with high accuracy (92% and 97% respectively) for assigning biological and social causes of child deaths, respectively. The CHERG VASA questionnaire was found relevant to the conceptual framework and valid in Pakistan. This valid tool can assign accurate medical and non-medical causes of child mortality cases occurring in Pakistan.

Analgesia and sedation in critically ill pediatric patients: an update from the recent guidelines and point of view

In the last decades, the advancement of knowledge in analgesia and sedation for critically ill pediatric patients has been conspicuous and relevant. Many recommendations have changed to ensure patients' comfort during their intensive care unit (ICU) stay and prevent and treat sedation-related complications, as well as improve functional recovery and clinical outcomes. The key aspects of the analgosedation management in pediatrics have been recently reviewed in two consensus-based documents. However, there remains a lot to be researched and understood. With this narrative review and authors' point of view, we aimed to summarize the new insights presented in these two documents to facilitate their interpretation and application in clinical practice, as well as to outline research priorities in the field.    Conclusion: With this narrative review and authors' point of view, we aimed to summarize the new insights presented in these two documents to facilitate their interpretation and application in clinical practice, as well as to outline research priorities in the field. What is Known: • Critically ill pediatric patients receiving intensive care required analgesia and sedation to attenuate painful and stressful stimuli. •Optimal management of analgosedation is a challenge often burdened with complications such as tolerance, iatrogenic withdrawal syndrome, delirium, and possible adverse outcomes. What is New: •The new insights on the analgosedation treatment for critically ill pediatric patients delineated in the recent guidelines are summarized to identify strategies for changes in clinical practice. •Research gaps and potential for quality improvement projects are also highlighted.

Is ketamine infusion effective and safe as an adjuvant of sedation in the PICU? Results from the Ketamine Infusion Sedation Study (KISS)

STUDY OBJECTIVE

We aimed to evaluate the efficacy and safety of ketamine in ensuring comfort and sparing conventional drugs when used as an adjuvant for analgesia and sedation in the Pediatric Intensive Care Unit (PICU) as a continuous infusion (≥12 h).

DESIGN

Observational prospective study.

SETTING

Tertiary-care-center PICU.

PATIENTS

All consecutive patients <18 years who received ketamine for ≥12 h between January 2019 and July 2021.

INTERVENTIONS

ketamine infusion for ≥12 h.

MEASUREMENTS AND MAIN RESULTS

Seventy-seven patients (median age 16 months, Interquartile Range (IQR) 7-43) were enrolled. Twenty-six percent of patients (n = 20) were paralyzed, while 74% (n = 57) were not. The median infusion duration was 90 h (IQR 39-193), with doses between 15 (IQR 15-20) and 30 μg/kg/min (IQR 20-50). At 24 h of ketamine infusion, values of COMFORT-B-Scale (CBS) were significantly lower compared with values pre-ketamine (p < 0.001). Simultaneously, doses/kg/h of opioids and benzodiazepines significantly decreased at 24 h (p < 0.001 and p = 0.002, respectively), while doses/kg/h of propofol (p = 0.500) and dexmedetomidine (p = 0.072) did not significantly change. Seventy-four percent of non-paralyzed patients (42/57) had a decrease in CBS ≥2 points with no increase of concomitant analgosedation drugs. Among paralyzed patients (n = 20), 13 (65%) had no increase of concomitant analgosedation within 24 h after ketamine initiation. Overall, 55/77 (71%) of patients responded to ketamine. The mean and maximum ketamine infusion dosages were significantly higher in the non-responders (p = 0.021 and 0.028, respectively). Eleven patients had adverse events potentially related to ketamine (hypersalivation, systemic hypertension, dystonia/dyskinesia, tachycardia, and agitation) and six patients required intervention (dose reduction, suspension, or pharmacologic therapy). None of the patients developed delirium during ketamine infusion.

CONCLUSIONS

Ketamine used as a continuous infusion in the PICU might represent a valid strategy to ensure comfort and spare opioids and benzodiazepines in difficult-to-sedate PICU patients. Adverse events are minor and easily reversible. Future study will be needed to investigate long-term outcomes.

Validating a measure of anticipated sex work-related stigma among male and female sex workers in Kenya

Sex workers face different types of sex work-related stigma, which may include anticipated, perceived, experienced, or internalized stigma. Sex work stigma can discourage health care seeking and hamper STI and HIV prevention and treatment efforts. There is a paucity of validated sex work-related stigma measures, and this limits the ability to study the stigma associated with sex work. A cross-sectional survey was conducted that measured anticipated sex work-related stigma among male and female sex workers in Kenya (N = 729). We examined the construct validity and reliability of the anticipated stigma items to establish a conceptually and statistically valid scale. Our analysis supported a 15-item scale measuring five anticipated sex work stigma domains: gossip and verbal abuse from family; gossip and verbal abuse from healthcare workers; gossip and verbal abuse from friends and community; physical abuse; and exclusion. The scale demonstrated good face, content, and construct validity. Reliability was good for all subscales and the overall scale. The scale demonstrated good model fit statistics and good standardized factor loadings. The availability of valid and reliable stigma measures will enhance efforts to characterize and address stigma among sex workers and ultimately support the protection, health and well-being of this vulnerable population.

Recommendations for analgesia and sedation in critically ill children admitted to intensive care unit

We aim to develop evidence-based recommendations for intensivists caring for children admitted to intensive care units and requiring analgesia and sedation. A panel of national paediatric intensivists expert in the field of analgesia and sedation and other specialists (a paediatrician, a neuropsychiatrist, a psychologist, a neurologist, a pharmacologist, an anaesthesiologist, two critical care nurses, a methodologist) started in 2018, a 2-year process. Three meetings and one electronic-based discussion were dedicated to the development of the recommendations (presentation of the project, selection of research questions, overview of text related to the research questions, discussion of recommendations). A telematic anonymous consultation was adopted to reach the final agreement on recommendations. A formal conflict-of-interest declaration was obtained from all the authors. Eight areas of direct interest and one additional topic were considered to identify the best available evidence and to develop the recommendations using the Evidence-to-Decision framework according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. For each recommendation, the level of evidence, the strength of the recommendation, the benefits, the harms and the risks, the benefit/harm balance, the intentional vagueness, the values judgement, the exclusions, the difference of the opinions, the knowledge gaps, and the research opportunities were reported. The panel produced 17 recommendations. Nine were evaluated as strong, 3 as moderate, and 5 as weak. Conclusion: a panel of national experts achieved consensus regarding recommendations for the best care in terms of analgesia and sedation in critically ill children.

Exploring the Face Validity of the Pain Numeric Rating Scale Among Healthcare Providers

ABSTRACT

BACKGROUND: Healthcare providers (HCPs) use the numeric rating scale (NRS) under the assumption that it provides reliable information from which to make decisions regarding analgesic administration. METHODS: We explored the face validity of the NRS using a prospective single-blinded observational design. Pre and post NRS scores were obtained from HCPs who submerged their hand in a bucket of ice water (pain stimulus). RESULTS: Despite a consistent similar pain source, individual HCPs rated their pain very differently (range, 2-10), and there was a significant difference in self-estimated pain tolerance (μ = 7.06 [SD, 1.43]) and actual pain scores (μ = 6.35 [SD, 2.2]; t = 4.08, P < .001). CONCLUSION: The findings indicate a limitation in the face validity of the NRS. The high variance in NRS scores reaffirms the subjectivity of pain perception and brings into question the utility of using NRS scores when determining analgesic dosages.

Content and Face Validation of a Novel, Interactive Nutrition Specific Physical Exam Competency Tool (INSPECT) to Evaluate Registered Dietitians' Competence: A Delphi Consensus from the United States

The nutrition-focused physical examination (NFPE) is an integral component of nutrition assessment performed by registered dietitian nutritionists (RDNs) to determine signs of malnutrition and other nutrition-related complications. Increased use of this essential skill among RDNs and the transformation of dietetics education to a competency-based model in the near future calls for appropriately validated tools to measure RDNs' NFPE competence. To fill the need for a validated competency tool, this study developed an Interactive Nutrition-Specific Physical Exam Competency Tool (INSPECT) utilizing the initial 70 items identified in the first phase of the study. The second phase of this study aimed to test the preliminary version of the INSPECT for content and face validity. An expert panel of 17 members provided consensus recommendations through the Delphi process. Internal consistency of the consensus was measured with Cronbach's alpha (α) and α of ≥0.70 was defined as acceptable a priori. Inter-rater agreement among the expert panel was determined using the intraclass correlation coefficient (ICC) and an a priori ICC of 0.75 to 0.9 was established as good and >0.9 as excellent agreement. The results showed acceptable face validity (α = 0.71) and excellent content validity for the INSPECT, with an internal consistency of α = 0.97 in the first round and α = 0.96 in the second round. The inter-rater agreement was also excellent with ICC = 0.95 for each of the Delphi rounds. A total of 52 items were retained from the preliminary version of the INSPECT. Open feedback from the experts allowed for the consolidation of 11 similar items for better scoring and evaluation and thus, a total of 41 items were included in the final version of the INSPECT. The final version of the INSPECT is currently being studied in real-life, multi-site clinical settings among practicing RDNs to examine construct validity, reliability, and item-level psychometric properties. Ultimately, the validated INSPECT will be available for the competency evaluation of RDNs practicing in clinical settings.

"Difficult to Sedate": Successful Implementation of a Benzodiazepine-Sparing Analgosedation-Protocol in Mechanically Ventilated Children

We sought to evaluate the success rate of a benzodiazepine-sparing analgosedation protocol (ASP) in mechanically ventilated children and determine the effect of compliance with ASP on in-hospital outcome measures. In this single center study from a quaternary pediatric intensive care unit, our objective was to evaluate the ASP protocol, which included opiate and dexmedetomidine infusions and was used as first-line sedation for all intubated patients. In this study we included 424 patients. Sixty-nine percent (n = 293) were successfully sedated with the ASP. Thirty-one percent (n = 131) deviated from the ASP and received benzodiazepine infusions. Children sedated with the ASP had decrease in opiate withdrawal (OR 0.16, 0.08–0.32), decreased duration of mechanical ventilation (adjusted mean duration 1.81 vs. 3.39 days, p = 0.018), and decreased PICU length of stay (adjusted mean 3.15 vs. 4.7 days, p = 0.011), when compared to the cohort of children who received continuous benzodiazepine infusions. Using ASP, we report that 69% of mechanically ventilated children were successfully managed with no requirement for continuous benzodiazepine infusions. The 69% who were successfully managed with ASP included infants, severely ill patients, and children with chromosomal disorders and developmental disabilities. Use of ASP was associated with decreased need for methadone use, decreased duration of mechanical ventilation, and decreased ICU and hospital length of stay.

Developing and Establishing Content Validity of Vignettes for Health Care Education and Research

The use of vignettes in research and education is well documented. Documentation of how vignettes are developed and content validity is established, however, are rare. The purpose of this paper is to describe a method for development and establishing content validity of vignettes that can be used to assess student performance and research participant outcomes. This three-phase method was designed to validate seven vignettes for a future research project. Content validity index survey and expert panel interviews were used to inform improvements in validity. Findings showed that clinical vignettes were improved with respect to content relevance (from 0.93 to 0.96) and importance (from 0.68 to 0.93). Developing validated vignettes is essential when used to measure outcomes in education and in research. This three-phase method of vignette development and validation is feasible and effective in improving content validity of vignettes and can be used in other education and research projects.

Midazolam Dose Optimization in Critically Ill Pediatric Patients With Acute Respiratory Failure: A Population Pharmacokinetic-Pharmacogenomic Study

OBJECTIVES

To develop a pharmacokinetic-pharmacogenomic population model of midazolam in critically ill children with primary respiratory failure.

DESIGN

Prospective pharmacokinetic-pharmacogenomic observational study.

SETTING

Thirteen PICUs across the United States.

PATIENTS

Pediatric subjects mechanically ventilated for acute respiratory failure, weight greater than or equal to 7 kg, receiving morphine and/or midazolam continuous infusions.

INTERVENTIONS

Serial blood sampling for drug quantification and a single blood collection for genomic evaluation.

MEASUREMENTS AND MAIN RESULTS

Concentrations of midazolam, the 1' (1`-hydroxymidazolam metabolite) and 4' (4`-hydroxymidazolam metabolite) hydroxyl, and the 1' and 4' glucuronide metabolites were measured. Subjects were genotyped using the Illumina HumanOmniExpress genome-wide single nucleotide polymorphism chip. Nonlinear mixed effects modeling was performed to develop the pharmacokinetic-pharmacogenomic model. Body weight, age, hepatic and renal functions, and the UGT2B7 rs62298861 polymorphism are relevant predictors of midazolam pharmacokinetic variables. The estimated midazolam clearance was 0.61 L/min/70kg. Time to reach 50% complete mature midazolam and 1`-hydroxymidazolam metabolite/4`-hydroxymidazolam metabolite clearances was 1.0 and 0.97 years postmenstrual age. The final model suggested a decrease in midazolam clearance with increase in alanine transaminase and a lower clearance of the glucuronide metabolites with a renal dysfunction. In the pharmacogenomic analysis, rs62298861 and rs28365062 in the UGT2B7 gene were in high linkage disequilibrium. Minor alleles were associated with a higher 1`-hydroxymidazolam metabolite clearance in Caucasians. In the pharmacokinetic-pharmacogenomic model, clearance was expected to increase by 10% in heterozygous and 20% in homozygous for the minor allele with respect to homozygous for the major allele.

CONCLUSIONS

This work leveraged available knowledge on nonheritable and heritable factors affecting midazolam pharmacokinetic in pediatric subjects with primary respiratory failure requiring mechanical ventilation, providing the basis for a future implementation of an individual-based approach to sedation.
