Children's psychological responses after critical illness and exposure to invasive technology

ABSTRACT. Children hospitalized in pediatric intensive care units (PICUs) are subjected to highly invasive interventions necessary in overcoming the critical period of their illness, yet little is known about their subsequent psychological adjustment. The purposes of this study were to compare the psychological responses of children hospitalized in a PICU with those of children hospitalized on a general ward and to identify clinically relevant factors that might be associated with psychological outcome. A prospective cohort design was used to follow 120 children for 6 months after PICU and ward discharge. Groups were compared on the children’s sense of control over their health, their medical fears, posttraumatic stress, and changes in behavior. Relationships between children’s responses and their age, the invasive procedures to which they were exposed, severity of illness, and length of hospital stay were also examined. No significant group differences were found. However, children who were younger, more severely ill, and who endured more invasive procedures had significantly more medical fears, a lower sense of control over their health, and ongoing posttraumatic stress responses for 6 months postdischarge. Findings indicate that regardless of the hospital setting, invasiveness coupled with length of stay and severity of illness in young children may have adverse long-term effects.

A systematic review of questionnaires measuring health-related empowerment.

The objective of this systematic review was to identify questionnaires that measure health-related empowerment in adults or families and demonstrated the best evidence of reliability and validity. A search of nine data bases identified 8,269 abstracts that referred to empowerment. Full article review was completed for abstracts that met the inclusion criteria or that could not be excluded with certainty (n = 124). Fifty distinct, modified, or translated questionnaires measuring empowerment were identified in 74 articles. Each was rated in terms of reliability and validity. One questionnaire had good evidence of reliability and validity, four had moderate evidence, and 45 had limited or no evidence. Limited or no evidence for reliability and validity for many questionnaires could relate in part to lack of consensus on the theoretical definition of, and indicators for measuring empowerment. We recommend that researchers use the questionnaire rated as having good evidence and that data on reliability and validity continue to be reported for other questionnaires.

‘It's okay, it helps me to breathe’: the experience of home ventilation from a child's perspective

There are few studies that focus on childrens subjective responses to home ventilation and how this in turn affects their daily lives. This multiple case study explored the experience of home ventilation from the childrens perspective. Data were collected from five children through observation and audiotaped interviews. Children expressed their physical and emotional relationship with the ventilator, stating: ‘Its okay. It helps me to breathe’–a theme that had a number of distinct dimensions. Other themes included the medicalization of childhood, being a child and hopes for the future. Unlike other study findings to date, the children in this study concluded that the technology was only one small part of their lives. Nurses must ensure that these children have an opportunity to communicate their perspectives, in order to provide care that is clinically effective and childcentered.

Strategies to increase research-based practice: interplay with unit culture.

Purpose: A major focus of clinical nurse specialist nursing practice is the integration of research findings into practice. The purpose of this study was to describe strategies used to facilitate research utilization (RU) by nurses in a practice setting. Design: This multiple-case study identified the strategies that clinical nurse specialists and masters degree-prepared nurse educators, working collaboratively, used to facilitate RU. Setting/Sample: The setting included 8 units in 4 sites of a university hospital with all willing nurses participating. Methods: Open-ended focus groups and individual interviews and observational sessions were conducted using investigator-designed interview guides. Comprehensive qualitative analysis led to identification of categories and themes related to RU and the unit culture that supported it. Findings: Findings demonstrated that strategies to facilitate RU by staff at the unit level included conducting original research, supporting nurses participating in research, assessing and meeting staff learning needs, promoting staff attendance at conferences, stimulating goal-setting for presentations and publications, encouraging and responding to new ideas, questioning practice and stimulating inquiry, capitalizing on expertise in research knowledge and skills, and generating information and material resources. Characteristics of unit culture were linked to varying degrees of success with these strategies. The interplay of strategies with unit culture and research-based practice is described. Conclusion: A wide repertoire of strategies is needed to facilitate RU, and the outcome of these strategies is influenced by the unit culture. Implications for Practice: Consideration of the findings and the scope of the strategies used by nurses in the study can help clinical nurse specialist and other nursing leaders facilitate the building of practice on research.

Include Them and They Will Tell You: Learnings From a Participatory Process With Youth

Encouraging youth voice, visibility, and active participation in adolescent-related research is strongly advocated in the literature. In this article, we describe how participatory approaches informed by arts-based methods (e.g., reflective writing, dramatization) were used with adolescents to enhance the research process in an exploratory study designed to develop and evaluate prevention resources for sexual risk-taking behaviors.Youth aged 15 to 17 years participated in iterative focus groups conducted over a 1-year period in school settings in Prince Edward Island, Canada. Descriptions of our experiences, strategies, and insights provide evidence for guiding practice to optimize adolescent participation in research.

A multidimensional approach to pain assessment in critically ill infants during a painful procedure.

Objectives:Inferring the pain level of a critically ill infant is complex. The ability to accurately extract the appropriate pain cues from observations is often jeopardized when heavy sedation and muscular blocking agents are administered. Near-infrared spectroscopy is a noninvasive method that may provide the bridge between behavioral observational indicators and cortical pain processing. We aimed to describe regional cerebral and systemic hemodynamic changes, as well as behavioral reactions in critically ill infants with congenital heart defects during chest-drain removal after cardiac surgery. Methods:Our sample included 20 critically ill infants with congenital heart defects, less than 12 months of age, admitted to the cardiac intensive care unit after surgery. Results:Cerebral deoxygenated hemoglobin concentrations significantly differed across the epochs (ie, baseline, tactile stimulus, noxious stimulus) (P=0.01). Physiological systemic responses and Face Leg Activity Cry Consolability (FLACC) pain scores differed significantly across the events (P<0.01). The 3 outcome measures were not found to be associated with each other. Mean FLACC pain scores during the painful procedure was 7/10 despite administration of morphine. Midazolam administration accounted for 36% of the variance in pain scores. Discussion:We demonstrated with a multidimensional pain assessment approach that significant cerebral, physiological, and behavioral activity was present in response to a noxious procedure in critically ill infants despite the administration of analgesic treatment. Considering that the sedating agent significantly dampened pain behaviors, assessment of cerebral hemodynamic in the context of pain seems to be an important addition.

Developing the Children’s Critical Illness Impact Scale: Capturing stories from children, parents, and staff*

Objective: With the evolution of pediatric critical care medicine has come an awareness of the ethical imperative of healthcare professionals to attend to the psychological sequelae of technologically intensive care. Recent attempts to measure psychological outcomes in these children have been limited. The purpose of this study was to develop a measure of posthospitalization distress, the Children’s Critical Illness Impact Scale (CCIIS), for children aged 6–12 yrs following pediatric intensive care unit hospitalization. Design: A measurement development study consisting of two phases: 1) item generation and scale formatting; and 2) item reduction and scale revisions. Items were generated following thematic analysis of qualitative data from focus groups and individual interviews with children, parents, and healthcare professionals. Children reviewed items for interpretability and importance and assessed scaling technique and item presentation; healthcare professionals further evaluated item relevance. Setting: The pediatric intensive care units of three quaternary care, Canadian pediatric teaching hospitals. Patients: Phase 1 included 18 children, 22 parents, and 12 healthcare professionals (n = 52). Phase 2 included eight children and four healthcare professionals (n = 12). Measurements and Main Results: Five key domains were identified in the thematic analyses: worries, fears, friends and family, sense of self, and behaviors. Thirty-six items were initially generated, and subsequent item reduction resulted in 23 items that were retained on the final scale. Items were generally rated extremely relevant and were judged to capture the content area (content validity index = 0.87). The CCIIS was easily understood, and the scaling format worked well. Older children preferred written items, while younger children will require a modified, pictorial version. Conclusions: The CCIIS is a new self-report measure with demonstrated content validity and specific relevance for young school-aged children following pediatric intensive care unit hospitalization. Valid, accessible, and developmentally appropriate measures are essential to identify high-risk children and, ultimately, promote healthy growth and development.

Affirming parental love in the pediatric intensive care unit.

Objective: To argue that that there has been a remarkable absence of discussion of the importance of parental love in the pediatric intensive care literature, and that this silence has been to the detriment of both medical and nursing pediatric intensive care practice. Conclusions: Research and anecdotal literature to date have focused on the negative changes that occur in the parental role during a childs pediatric intensive care unit admission. In contrast, the love that a parent holds for his or her child is profoundly positive and stable; it is not a “role” that can be taken away or threatened. It is proposed that the recognition and acknowledgment of this love will alter the critical care encounter for parents, physicians, and nurses and result in a better understanding by the staff of parental attitudes and behaviors. This may be particularly effective in situations where it is perceived that unreasonable demands are being made for futile therapy.

Cerebral near-infrared spectroscopy as a measure of nociceptive evoked activity in critically ill infants

Signs of pain may be subtle or absent in a critically ill infant. The complex nature of pain may further obscure its identification and measurement. Because the use of monitoring and neuroimaging techniques has become more common in pain research, an understanding of these specialized technologies is important. Near-infrared spectroscopy (NIRS) is a noninvasive technique for monitoring tissue hemodynamics and oxygenation. There are indications that NIRS is capable of detecting the cerebral hemodynamic changes associated with sensory stimuli, including pain, in infants. These developments suggest that NIRS may play an important role in research focusing on pain perception in critically ill infants. The present review briefly describes the cortical responses to noxious stimuli, which parallel cerebral hemodynamic responses to various stimuli. This is followed by an overview of NIRS technology including a summary of the literature on functional studies that have used NIRS in infants. Current NIRS techniques have well-recognized limitations that must be considered carefully during the measurement and interpretation of the signals. Nonetheless, until more advanced NIRS techniques emerge, the current devices have strengths that should be exploited.

Maternal touch and talk for invasive procedures in infants and toddlers in the pediatric intensive care unit.

The aim of this single-blind, randomized, crossover trial was to test the effect of Touch & Talk (T&T) for infants and toddlers less than 36 months of age (N = 65) in the pediatric intensive care unit on their physiological stability and recovery to an invasive procedure. In the T&T condition, mothers touched, sang, or told stories or rhymes to their child during an invasive procedure. In the control condition, the mothers did not have contact with their child. Physiological measures included heart rate, heart rate variability, and oxygen saturation range during the procedure and change from baseline. Time from the end of the procedure until the heart rate returned to baseline levels gave the recovery time. Analysis was conducted using repeated-measures analysis of covariance. There were no significant differences on any of the physiological parameters by condition during the procedure. However, when controlling for severity of illness, recovery was faster with mothers.
