Hypotensive Events in Pediatric Patients Receiving Dexmedetomidine for MRI.

PURPOSE: Dexmedetomidine, the preferred pediatric sedating agent for magnetic resonance imaging (MRI), has the side effect of hypotension. Newer recommendations for reporting adverse events in pediatric procedural sedation include using a two-pronged definition. Our aim was to describe the incidence of hypotension in patients undergoing sedated MRI and to identify demographic and clinical factors associated with hypotension, applying a two-pronged definition, where a numerical threshold/clinical criterion must be met as well as at least one clinical intervention performed. DESIGN: An observational cohort study. METHODS: Medical record data were extracted for outpatients less than 18 years of age sedated primarily with dexmedetomidine for MRI in a single center for over a seven-year period. Patients who received propofol as an adjunct were also included. Hypotension was defined using a two-pronged approach, as a 20% reduction in systolic blood pressure from baseline lasting ≥10 minutes, coupled with a fluid bolus. Analysis included descriptive statistics, t tests and logistic regression using discrete-time survival analysis. FINDINGS: Of the 1,590 patient encounters, 90 (5.7%) experienced hypotension. Males were significantly more likely to have hypotension. Patients with hypotension had overall longer appointment times, including longer sedation times and recovery time. Greater blood pressure (BP) variability in the preceding 20 minutes also increased the risk of hypotension. CONCLUSIONS: Our lower incidence of hypotension is likely related to the two-pronged intervention-based definition used, as it likely more accurately reflects clinically meaningful hypotension. To our knowledge, this is the first study using this approach with this population. Research further examining the relationship between prolonged sedation, blood pressure variability, gender, hypotension, and recovery time is needed. Understanding these relationships will help interdisciplinary teams, including nurses in pediatric procedural areas, to reduce the incidence of hypotension, potentially maximize patient safety, and optimize throughput.

Using a Cascading Approach to Improve Multisite Study Procedures.

BACKGROUND: Multisite studies offer larger, more diverse samples to successfully capture populations and clinical practices of interest at the point of care. However, investigators face challenges with site recruitment and sampling, differences in clinical practices across sites, and data integrity. Addressing these issues a priori can improve the rigor and reproducibility of the research. OBJECTIVE: This article aims to describe a cascading approach to multisite research. An exemplar is provided of a study using this approach, which aimed to evaluate the prevalence of pain and the pain management practices provided to critically ill children in pediatric intensive care units in the United States. METHODS: The cascading approach includes two or more pilot study procedures with a progressively increasing number of sites prior to a full-scale study. Following each pilot, study procedures are evaluated; feedback was obtained from site personnel and content experts; procedures were revised accordingly; approvals were obtained; sites were trained; and the revised procedures are repeated with a larger, more diverse number of sites. RESULTS: In the exemplar provided, improvements in the efficiency and integrity of data collection were noted for the full-scale study following the pilots. All sites that completed the agreements and approvals for study participation were retained for the duration of the two pilots and full-scale study. DISCUSSION: Borrowing from principles of process improvement, the cascading approach allows knowledge to be gained regarding site differences and informs the revision of study procedures while potentially maximizing efficiency and data integrity, minimizing site burden, and maintaining site engagement for multisite studies.

Pain Assessment and Management for a Chemically Paralyzed Child Receiving Mechanical Ventilation.

BACKGROUND: Pain assessment in the pediatric intensive care unit (PICU) is complex, specifically for children receiving mechanical ventilation who require neuromuscular blockade (NMB). No valid pain assessment method exists for this population. Guidelines are limited to using physiologic variables; it remains unknown how nurses are assessing and managing pain for this population in practice. OBJECTIVES: To describe how PICU nurses are assessing and managing pain for children who require NMB. METHODS: A cross-sectional quantitative design was used with an electronic survey. Nurses were asked to respond to 4 written vignettes depicting a child who required NMB and had a painful procedure, physiologic cues, both, or neither. RESULTS: A total of 107 PICU nurses answered the survey. Nurses primarily used behavioral assessment scales (61.0%) to assess the child's pain. All nurses reported that physiologic variables are either moderately or extremely important, and 27.3% of nurses used the phrase "assume pain present" formally at their organization. When physiologic cues were present, the odds of a nurse intervening with a pain intervention were 23.3 times (95% CI, 11.39-53.92; P < .001) higher than when such cues were absent. CONCLUSIONS: These results demonstrate variation in how nurses assess pain for a child who requires NMB. The focus remains on behavioral assessment scales, which are not valid for this population. When intervening with a pain intervention, nurses relied on physiologic variables. Decision support tools to aid nurses in conducting an effective pain assessment and subsequent management need to be created.

Nurses' Experiences Caring for Children With Neuroblastoma Receiving 131I-Metaiodobenzylguanidine Therapy: A Qualitative Descriptive Study.

Background: Neuroblastoma, the most common extra-cranial solid tumor found in children, carries a high mortality rate due to challenges with metastatic disease at diagnoses and relapse. 131I-Metaiodobenzylguanidine (I-MIBG) therapy provides targeted radiotherapy to treat neuroblastoma, but requires children to be isolated for radiation exposure, with limited access to the healthcare team while hospitalized. There is minimal research outlining the nurses' perspectives on caring for this patient population. Therefore, the aim of this study was to describe the nurses' experiences caring for children receiving 131I-MIBG therapy, focusing on nursing care, challenges, radiation exposure, and preparation. Methods: Ten nurses were recruited using purposeful sampling for this qualitative descriptive study. Semi-structured interview guides and conventional qualitative content analysis guided the data collection and analysis. Results: Nurses overwhelmingly felt isolated from their patients and a decreased sense of connection with the child. Although nurses felt prepared, they had more anxiety with the first patient experience and identified that parent engagement was essential. Overall, nurses shared they had support from written materials outlining the protocols, and members of the multidisciplinary team. More concern for radiation exposure was expressed by nurses of childbearing age and with handling bodily fluids. Discussion: Findings suggest that nurses would benefit from simulation experiences to help prepare for radiation exposure safety, strategies to engage the family in the child's care, and interacting with a child in single-room isolation. Because programs differ around the US, additional research exploring nurses' experiences is warranted to evaluate the best successes in providing 131I-MIBG therapy.

Variability in qualifications for principal investigator status in research studies by nurses: A call for clarification.

PURPOSE: To describe existing guidance for qualifications of principal investigator s (PI s) of human subjects research and explore how they are operationalized for pediatric nurse scientists and clinical nurses in children's hospitals. DESIGN AND METHODS: After reviewing federal regulations, accreditation guidelines, and the literature, a convenience sample of members of the National Pediatric Nurse Scientist Collaborative (NPNSC). Participants completed a 33-item survey that included questions about Institutional Review Board (IRB), guidelines, and policies for PI status at their affiliated children's hospitals. RESULTS: The survey was electronically disseminated to 179 members of NPNSC through the Collaborative's listserv. Of the 39 members who responded, 90% hold a PhD and 80% practice in a free-standing children's hospital, nearly all of which (93%) are recognized as Magnet® hospitals. While the majority of respondents indicated that nurse scientists and other nurses were allowed to be PIs of research studies, educational requirements for PI status varied, with 3% requiring a PhD, 15% a baccalaureate degree, and 10% a graduate degree. 54% of respondents reported there was no degree requirement for PI status; however15% reported that even doctorally prepared nurse scientists cannot serve as PIs of research studies at their affiliated children''s hospitals. CONCLUSIONS: The survey identified substantial variability in requirements for PI status and potential barriers to pediatric nurses conducting independent research as PIs at children's hospitals. PRACTICE IMPLICATIONS: Operationalizing existing guidance will expand inclusion of nurse scientist expertise in human subjects research.

The Experience of Children With Neuroblastoma and Their Parents During Single-Room Isolation for 131I-Metaiodobenzylguanidine Therapy: A Qualitative Descriptive Study.

Background: Administration of 131I-metaiodobenzylguanidine (131I-MIBG) for neuroblastoma requires hospitalization in single-room isolation and limits caregiver physical contact due to the child's radioactive burden. Though used for decades, there is a dearth of research on the experiences of children and their parents while isolated. Methods: This qualitative descriptive study evaluated the experience of children with neuroblastoma undergoing single-room isolation for 131I-MIBG therapy and their parents. Ten nurses, nine parents, and five children were interviewed; transcripts were analyzed applying a conventional content analysis approach. Results: Child themes included overall experiences ranging from positive to negative; emotional stress was common; symptoms were common but mostly managed; the children were adequately prepared for isolation; and audiovisual technology and entertainment helped. The indwelling urinary catheter was a source of emotional stress and/or pain for several children. Parent themes included I thought it was going to be a lot worse; it gets better with time; feeling concerned and overwhelmed; prepared as much as you can be; and you feel like you're not alone. Discussion: Findings suggest that children and parents would benefit from additional coping support interventions to address emotional distress. Efforts should be made to identify other sources of technology or room designs that can maximize the child's sense of connection with parents and healthcare professionals. Additional research is needed to examine the impact of this isolation experience on the long-term psychological outcomes of children and parents.

Predicting Who Receives Nonpharmacologic Pain Interventions in the Pediatric Intensive Care Unit.

AIMS: The majority of patients in the pediatric intensive care unit (PICU) experience pain daily, while nonpharmacologic interventions are indicated for pain management in children, there is limited information on which nonpharmacologic interventions are provided in the PICU and which patients receive those interventions. The aim of this descriptive correlational secondary data analysis was to determine what nonpharmacologic interventions were recorded in the electronic health record of PICU patients and patterns in use by patient demographics. SETTING/SUBJECTS: All patients hospitalized in 15 participating PICUs are located within 12 unique children's hospitals across the United States were eligible for participation. METHODS: Nonpharmacologic interventions used in the PICU were identified and differences between patients who did and did not receive those interventions were examined using Fisher's exact test. A generalized linear mixed effects model was constructed to determine patient characteristics that predict nonpharmacologic pain intervention application. RESULTS: Of 220 enrolled patients, 97 (44%) had nonpharmacologic pain interventions recorded in their electronic health record. The most frequently recorded interventions included repositioning (65%), decreasing environmental stimuli (55%), caregiver presence (37%), distraction (23%), and music therapy (20%). Children who had moderate to severe pain were most likely to receive nonpharmacologic pain interventions. CONCLUSIONS: Nonpharmacologic pain management is applied inconsistently across PICUs and may be underdocumented or underutilized. Additional research is needed to determine when nurses use nonpharmacologic pain interventions, their rationale for applying these interventions across differing groups, and the effectiveness of these interventions in managing pain in critically ill children.

Pain in the Pediatric Intensive Care Unit: How and What Are We Doing?

BACKGROUND: Pain management in critically ill children is complex. Epidemiological research is needed to identify how often patients in pediatric intensive care units experience pain and the practices being used to lessen pain. OBJECTIVES: To describe pain assessment and intervention practices in pediatric intensive care units, determine the prevalence of pain and painful procedures, and identify characteristics of children with moderate to severe pain. METHODS: A 24-hour observational cohort study was conducted in 15 units. Nurses completed surveys regarding patients' communicative ability. Patients' records were reviewed for pain assessments, painful procedures, and pharmacologic and nonpharmacologic interventions. RESULTS: For the 220 patients in this study, pain was assessed a median (interquartile range) of 10 (7-13) times, usually with behavioral pain scales. Sixty-eight percent of patients received pharmacologic interventions and 44% received nonpharmacologic interventions. Fentanyl was the most common analgesic provided. Repositioning was the most common nonpharmacologic intervention. Forty-five percent of patients had pain and 24% had moderate to severe pain. Patients experienced a median (interquartile range) of 7 (2-15) painful procedures in 24 hours. More frequent pain assessments and pharmacologic interventions and the ability to communicate were associated with moderate to severe pain. No patient in the moderate to severe pain category received neuromuscular blockers. CONCLUSIONS: Critically ill children experience pain and multiple painful procedures daily. Assessment and intervention practices vary considerably. Research is needed to establish best practices for pain assessment in patients with limited communicative ability and to determine which pain management strategies improve patients' outcomes.

Targeted Simulation Instructor Course for Nursing Professional Development Specialists.

Practical training for nursing professional development specialists in the facilitation of clinical simulations was implemented using a six-step curriculum development framework. General and targeted needs assessments were conducted. Methods used to apply needs assessment findings into the course design and delivery and the participant's responses via program evaluations are described. The process used to develop this training may be applied by other nursing professional development departments to prepare educators in the delivery of simulated-based learning experiences.

Nurses' Beliefs Regarding Pain in Critically Ill Children: A Mixed-Methods Study.

The purpose of this study was to provide a current and comprehensive evaluation of nurses' beliefs regarding pain in critically ill children. DESIGN AND METHODS: A convergent parallel mixed-methods design was used. Nurse beliefs were captured via questionnaire and interview and then compared. RESULTS: Forty nurses participated. Most beliefs reported via questionnaire were consistent with effective pain management practices. Common inaccurate beliefs included the need to verify pain reports with physical indicators and the pharmacokinetics of intravenous opioids. Beliefs commonly shared during interviews concerned the need to verify pain reports with observed behavior, the accuracy of pain reports, the need to respond to pain, concerns regarding opioid analgesics, and the need to "start low" with interventions. Convergent beliefs between the questionnaire and interview included the use of physical indicators to verify pain, the need to take the child's word when pain is described, and concerns regarding negative effects of analgesics. Divergent and conflicting findings were most often regarding the legitimacy of a child's pain report. CONCLUSIONS: Findings from this study regarding the accuracy of nurses' pain beliefs for critically ill children are consistent with past research. The presence of divergent and conflicting responses suggests that nurses' pain beliefs are not static and may vary with patient characteristics. PRACTICE IMPLICATIONS: While most nurses appreciate the risks of unrelieved pain in children, many are concerned about the potential adverse effects of opioid administration. Interventions are needed to guide nurses in minimizing both of these risks.

PICU Nurses' Pain Assessments and Intervention Choices for Virtual Human and Written Vignettes.

The purpose of this concurrent mixed-methods study was to 1) examine the factors pediatric intensive care unit nurses consider when assessing and intervening for children who report severe pain and to 2) determine the effect of child behavior and diagnosis on the nurses' pain ratings and intervention choices for written and virtual human vignettes. Quantitative and qualitative results substantiated that despite recommendations to use self-report, many PICU nurses use behavior as the primary indicator to assess and treat pain, even when a child is old enough to articulate pain intensity and there is sufficient cause for pain to be present.

Development and validation of a virtual human vignette to compare nurses' assessment and intervention choices for pain in critically ill children.

INTRODUCTION: As virtual experiences are increasingly used in health care training and research, it is important that adequate processes are applied for developing valid scenarios. We describe the development and validation of virtual human (VH) vignettes, computer-generated scenarios with animated patients and clinical information, for a mixed-methods study regarding nurses' assessment and intervention choices for critically ill children's pain. METHODS: We followed the case development and review process for high-fidelity simulation case scenarios, including the use of validated written vignettes and content experts. Forty nurses described their pain assessment and intervention choices for the newly derived VH vignettes and completed a pain questionnaire. Nurses' reports of VH vignette consistency with their professional experience and recognition of VH facial expressions were evaluated to establish face validity. Their pain ratings for the VH and written (questionnaire) vignettes were evaluated for convergent validity. Qualitative content analysis, descriptive statistics, correlations, and paired t tests were used. RESULTS: Most nurses (68.4%) supported vignette consistency with their professional experience. Facial expression recognition was 98.4%. Smiling children's pain was rated significantly lower than grimacing children in both VH and written vignettes. Pain was rated significantly lower for grimacing children in the VH vignettes than the written vignettes. Virtual human vignette pain ratings were strongly correlated with their written counterparts. CONCLUSIONS: This process was effective for developing VH vignettes that demonstrated good face validity with participants and convergent validity with written vignettes. Virtual human vignettes may be useful in studying the influence of facial actions on nurses' choices for children's pain assessment and treatment.

A critique of the National League for Nursing/Jeffries simulation framework.

AIMS: To present a critique of the National League for Nursing/Jeffries simulation framework. DESIGN: Fawcett's criteria for theory analysis and evaluation are used. BACKGROUND: Use of simulated learning experiences in nursing education is widespread; a sound framework to guide educators across the globe in implementing these experiences effectively is essential. The basic assertion of the National League for Nursing/Jeffries simulation framework is that student-learning outcomes are influenced by the concepts of teacher, student, educational practices, and simulation design characteristics. DATA SOURCES: A literature search was performed using Cumulative Index to Nursing and Allied Health Literature, PubMed and Google Scholar to identify studies published in the English language, between 2005-June 2011, where the National League for Nursing/Jeffries simulation framework was tested or used as a theoretical framework for research. DISCUSSION: Sixteen publications (two articles in press) from the USA and UK were identified using the framework to guide research; outcomes included increased student satisfaction, confidence, and improved skill performance. IMPLICATIONS FOR NURSING: As a newer theoretical framework, the National League for Nursing/Jeffries simulation framework offers promise to guide the construction and implementation of simulation experiences resulting in positive student outcomes. CONCLUSION: Empirically supported definitions of concepts would strengthen the framework and help educators to consistently produce and identify positive outcomes. Additional rigorous research is necessary to further test relationships among concepts and the associated concept variables in the framework. More studies outside of the United States are needed to confirm the framework is relevant to nursing programs in other countries.
