Melhoria do outcome da pessoa em situação crítica com lesão cerebral secundária: intervenção especializada de enfermagem / Improving the outcome of people in critical situations with secondary brain injury: specialized nursing intervention

A Lesão Cerebral Secundária é um processo fisiopatológico complexo, o qual desencadeia inúmeras respostas inflamatórias que conduzem à morte de neurónios, por vezes de forma irreversível. Este fenómeno pode surgir horas ou dias após uma lesão cerebral primária, independentemente da sua etiologia, e a equipa de enfermagem desempenha um papel preponderante na minimização do impacto causado por este processo. A intervenção de enfermagem deve ser pautada pela vigilância e deteção célere de focos de instabilidade, garantindo a segurança do utente, e direcionada no sentido da otimização da oxigenação e perfusão cerebral adequadas, através de intervenções interdependentes e, particularmente de intervenções autónomas, com o objetivo major de minimizar o impacto neurológico e melhorar o outcome final, numa perspetiva de melhoria contínua da qualidade dos cuidados prestados. Com o intuito de desenvolver competências no cuidado ao doente neurocrítico, de uma forma especializada, foi realizado um estágio em contexto de cuidados intensivos e serviço de urgência. A realização da revisão integrativa da literatura, acerca da influência do posicionamento corporal na gestão da pressão intracraniana e pressão de perfusão cerebral, enquanto intervenção autónoma de enfermagem, subsidiou a componente teórica e científica. Este relatório foi desenvolvido no âmbito do curso de Mestrado em Enfermagem na área de especialização da pessoa em situação crítica e pretende descrever, de forma crítica e reflexiva, o percurso formativo desenvolvido, perspetivando-se o olhar sobre este tema nas teorias de enfermagem Nursing as Caring e Technological Competency as Caring in Nursing.

The secondary brain injury is a complex physio-pathological process that triggers a range of inflammatory responses that lead to the death of neurons, sometimes, irreversibly. This phenomenon may surface hours, or even, days after the primary brain injury regardless of its aetiology, and the nursing team playing a critical role minimizing the impacts caused by this process. The nursing assistance should be steered towards both vigilance and quick detection of instability hot spots, ensuring, patient safety steered towards the optimization of proper brain oxygenation and perfusion, through independent interventions, and specifically autonomous interventions with the ulterior goal of minimizing the neurological impact while improving the outcome, all from the viewpoint of continual improvement of the provided care. With the purpose of further consolidating the skill set, an internship in intensive care and emergency service was also undertaken. The integrative literature review on the body positioning and its influence on the management of intracranial and perfusion pressures of the brain, as an autonomous procedure, subsidized the theoretical and scientific components. This report was written for the study plan of the Master of Nursing in Critical Care and aims to describe and discuss the learning path while rooting the topic in modern nursing theories Nursing as Caring and Technological Competency as Caring in Nursing.

Development, Reliability, and Validity of the Perceptions of Brain Injury Survey.

BACKGROUND AND PURPOSE: The purpose of this study was to assess psychometric properties of the Perceptions of Brain Injury Survey (PBIS), an instrument designed to assess nurses' perceptions and preparation to care for patients with traumatic brain injury (TBI). METHODS: We adapted two instruments to create the PBIS, and 724 nurses completed the PBIS at three hospitals. RESULTS: Final instrument has 66 items and is composed of four subscales, which can be used independently. Results showed Cronbach's alpha for the overall scale was excellent (.93) and alphas for each composite subscale were acceptable to excellent (.73-.93). Findings also suggest good discriminant validity and evidence of external validity. CONCLUSIONS: The PBIS is a reliable and valid measure for assessing nurses' perceptions of caring for patients with TBI in practice or research.

Relationship continuity and person-centred care: An exploratory mixed-methods investigation of spousal partners' responses to the challenging care needs of those with acquired brain injury.

Some partners of people with an acquired brain injury experience the person with the injury and their relationship as continuous with the pre-injury person and relationship, but others experience the person and relationship as very different to what went before. Previous qualitative research has suggested that the experience of continuity may promote a more person-centred approach to how partners respond to challenging care needs. Given the value of triangulating evidence, this exploratory study used a mixed-methods design to investigate this suggestion. Twenty-six partners of people with an acquired brain injury completed the Birmingham Relationship Continuity Measure and a semi-structured interview about their response to challenging care needs. Interviews were coded and scored to provide a measure of the extent to which the participants' understanding, management and emotional responses showed a person-centred approach. The findings supported the hypothesis. Greater continuity was significantly correlated with a more person-centred approach. Associating relationship continuity and person-centred care is a novel approach to the issue of how family relationships may impact on care quality. Person-centred care can have important benefits for both the giver and receiver of care. Whether it can be promoted through fostering a sense of continuity in the relationship merits further investigation.

Routine Neurological Assessments by Nurses in the Pediatric Intensive Care Unit.

BACKGROUND: Brain injury with changes in clinical neurological signs and symptoms can develop while children are undergoing treatment in the intensive care unit. Critical care nurses routinely screen for neurological decline by using serial bedside neurological assessments. However, assessment components, frequency, and communication thresholds are not standardized. OBJECTIVES: To standardize neurological assessment procedures used by nurses, improve compliance with physicians' ordering and nurses' documentation of neurological assessments, and explore the frequency with which changes from preillness neurological status and previous assessments can be detected by using the assessment tool developed. METHODS: A quality improvement intervention was implemented during a 1-year period in a 55-bed pediatric intensive care unit with 274 nurses. Procedures for neurological assessment by nurses were standardized, a system for physicians to order neurological assessments by nurses at a frequency based on the patient's risk for brain injury was developed and implemented, and a system to compare patients' current neurological status with their preillness neurological status was developed and implemented. RESULTS: Process metrics that focused on compliance of ordering and documenting the standardized neurological assessments indicated improvement and sustained compliance greater than 80%. Exploratory analyses indicated that 29% of patients had an episode of neurological decline and that these episodes were more common in patients with developmental disabilities than in patients without such disabilities. CONCLUSIONS: Compliance with physicians' ordering and nurses' documentation of standardized neurological assessments significantly increased and had excellent sustainability. Further work is needed to determine the sensitivity of standardized nurses' neurological assessment tools for clinically meaningful neurological decline.

Religious Coping in Caregiver of Patients with Acquired Brain Injuries.

Caregivers play a crucial role in physical and psychological management in terms of assistance. For this reason, it is important for caregivers to find better coping strategies to minimize a possible physical and emotional burden. The aim of our study is to demonstrate how the religious coping can influence the burden of caregivers about health care of patients with severe brain injuries. Caregivers were, respectively, divided into two groups: 31 religious believers and 20 unbelievers. We submitted the questionnaires to participants, which investigate the caregiver burden, presence of depressive symptoms and kind of coping strategies adopted. Our results demonstrated that participants with religious belief used avoidance strategies more frequently compared to non-believers' group. We want to improve adaptive coping strategies to upgrade the awareness of caregiver, supporting burden and distress. A problem-solving training might improve quality of life in terms of social and psychological wellness.

The Cue-Response Theory and Nursing Care of the Patient With Acquired Brain Injury.

The cue-response theory is herewith proposed to replace the coma cue-response conceptual framework as a nursing theory for care of patients with acquired brain injury (ABI). After ABI, nurses assess patients and develop an understanding of their condition by interpreting meaning from physiologic and observational or behavioral cues. These interpretations form the basis for optimizing the timing of discrete nursing interventions; the outcome of which influences the trajectory toward recovery or toward secondary brain injury. The cue-response theory applies specifically for nurses' use to determine which interventions should be used and when those interventions should be carried out. The theory recognizes the knowledge potential and knowledge produced in the context of nursing care of all patients with ABI, not just those with coma, and broadens our understanding of how the timing of nursing interventions directly impacts secondary brain injury and the brain entropy state.

Caregiver burden and family functioning in different neurological diseases.

Aim of this study is to examine caregiver burden and family functioning in different neurological conditions. Forty-two primary caregivers of patients with Amyotrophic Lateral Sclerosis (ALS), Alzheimer's Disease and other dementia (AD), Parkinson's Disease (PD), Acquired Brain Injuries (ABI) and Multiple Sclerosis (MS) were administered scales for the evaluation of caregiver burden (CBI) and family functioning (FACES IV). Caregiver burden was overall high, with caregivers of patients with ALS and ABI having exceeded the CBI cut-off score for possible burn-out. The average scores of caregivers of patients with AD or other dementia and PD were close to the cut-off score, whereas those of caregivers of patients with MS were significantly lower than the others. Family cohesion, family satisfaction and the quality of family communication were associated with reduced levels of caregiver burden, whereas disengagement was associated with a higher burden. The data from the present study confirm that caregiver burden is a relevant issue in the context of neurological diseases, especially for those causing higher degrees of impairment. Significant correlations with family functioning emerged as well, highlighting the importance of studying and treating caregiver burden within the context of family relations.

Inconsistency in Reporting Variables Related to Intracranial Pressure Measurement in Scientific Literature.

PURPOSE: To assess whether the collection and communication of intracranial pressure (ICP) values were standardized and reproducible. METHODS: Integrative review of clinical trials (n = 357) reporting ICP as a variable. RESULTS: Only 24.1% of studies reported adequate data required for replication. Of the 357 reports, 342 provided information about the design, 274 discussed sampling strategy, 294 identified the ICP device type, 312 provided a unit of measure, 121 provided anatomical localization for measuring ICP, and 83 provided information about patient positioning. CONCLUSIONS: The majority of literature evaluated did not provide enough data for replication of results. Measuring and reporting ICP in the scientific literature is not standardized. A uniform standard would strengthen the quality of the evidence in neurocritical care and neurosurgical literature and better establish clinical guidelines for ICP management in neurologically injured patients.

Pupillometry Trends in the Setting of Increased Intracranial Pressure.

Serial pupil examinations remain a mainstay of neurological assessments performed by neuroscience nurses. Integration of pupillometer technology has increased in recent years, because of its ability to address limitations of manual examinations and to evaluate trended data over time. Preliminary research has linked pupillometer values to intracranial pressure (ICP) values, but data on pupillary changes in the setting of increased ICP remain sparse. The purpose of this study was to determine trends in pupillometer values in the setting of increased ICP among critically ill patients with neurological injury. This is a secondary analysis of data where serial pupillometer and ICP readings were recorded hourly on adult patients with neurological injury necessitating critical care management. More than 2100 paired serial pupillometer and ICP readings were obtained from 76 subjects, with a total of 2107 paired readings for the left eye and 2175 for the right eye. There were statistically significant differences in pupillometry values in the setting of increased ICP. Time series analysis indicates that spikes in ICP values resulted in corresponding variations in pupillometer values. Use of automated pupillometry remains a value adjunct to traditional invasive therapies. Evaluation of trended data may provide insight into ICP elevations in the absence of invasive monitoring and warrants additional research.

Adaptación de la escala ESCID para medir el dolor en pacientes críticos con daño cerebral / Adaptation of the ESCID scale to measure pain in critical patients with brain damage

OBJETIVO: evaluar la validez de constructo y la fiabilidadde la adaptación de la escala de conductas indicadoras de dolor (ESCID), para valorar el dolor en pacientes críticos con daño cerebral, no comunicativos y sometidos a ventilación mecánica. MÉTODO: sujetos: estudio multicéntrico, observacional. Se llevará a cabo en pacientes críticos con lesión cerebral adquirida, mayores de edad, sometidos a ventilación mecánica invasiva y sin capacidad de comunicación, ingresados en unidades de cuidados intensivos de cuatro hospitales universitarios de tercer nivel de la Comunidad de Madrid. En todos los sujetos se evaluará el dolor con dos instrumentos simultáneamente (ESCID-DC y videograbación). La evaluación del dolor con ESCID-DC se realizará por dos observadores independientes con resultado ciego entre ellos, ante la aplicación de dos procedimientos dolorosos (aspiración de secreciones traqueales y presión en lecho ungueal), y un procedimiento no doloroso. La medición se efectuará únicamente una vez por cada paciente y procedimiento. La medición del dolor se hará en tres momentos: cinco minutos antes, durante y 15 minutos después de cada procedimiento. Cinco minutos antes de iniciar los procedimientos y hasta diez minutos después, dos videocámaras (una enfoca el cuerpo completo, otra solo la cara) captarán imágenes y audio, para posteriormente analizar los cambios gestuales y corporales del sujeto en cada momento, y poder correlacionarlos con los ocho indicadores conductuales de la escala ESCID-DC. CONCLUSIONES: contar con una escala de este tipo con buenas propiedades psicométricas mejorará el manejo del dolor de los pacientes con daño cerebral y, por tanto, la eficacia del tratamiento

OBJECTIVE: to evaluate the validity of the concept and the reliability of the adaptation of the Scale of Behavior Indicators of Pain (ESCID) in order to assess pain in critical patients with brain damage, who are non-communicative and undergoing mechanical ventilation. METHOD: subjects: a multicenter observational study. It will be conducted on critical patients with acquired brain damage, of age, undergoing invasive mechanical ventilation, and unable to communicate, who have been admitted to intensive care units from four 3rd level University Hospitals from the Community of Madrid. Pain will be evaluated in all subjects with two instruments simultaneously (ESCID-DC and video recording). Pain evaluation through ESCID-DC will be conducted by two independent observers with blind results between them, with the application of two painful procedures (aspiration of tracheal secretions and pressure on the nail bed) and a non-painful procedure. Measurement will only be conducted once per patient and procedure. Pain measurement will be conducted at three time points: fiveminutes before, during, and fifteenminutes after each procedure. Five minutes before initiating the procedure and up to ten minutes afterwards, two video cameras will capture images and audio (one will focus on the entire body, the other one only on the face), in order to capture and subsequently analyze the gestural and body changes of the subject at each moment, and to be able to correlate them with the eight behavior indicators of the ESCID-DC scale. CONCLUSIONS: the availability of this type of scale, with good psychometric properties, will improve pain management for patients with brain damage and, therefore, treatment efficacy

Changes in Caregivers Lifestyle after Severe Acquired Brain Injury: A Preliminary Investigation.

INTRODUCTION: Severe acquired brain injury (sABI) is considered the most common cause of death and disability worldwide. sABI patients are supported by their caregivers who often exhibit high rates of psychological distress, mood disorders, and changes in relationship dynamics and family roles. OBJECTIVES: To explore lifestyle changes of caregivers of sABI patients during the postacute rehabilitation, by investigating possible differences between primary and secondary caregivers. Primary caregivers spend most of the time with the patient, providing daily care and taking most responsibility for the day-to-day decisions, while secondary caregivers are those who provide additional support. METHODS: Three hundred forty-seven caregivers of sABI patients were asked to fill in an unpublished self-report questionnaire to explore their possible lifestyles changes. RESULTS: A statistically significant difference was found between primary and secondary caregivers in time spent in informal caregiving (p<0.001). The primary caregivers reduced all leisure activities compared to secondary carers (p<0.05). CONCLUSIONS: By comparing the percentage of leisure activities performed by caregivers before and after the patient's sABI onset, all caregivers showed high percentages of changes in lifestyle and habits, even though primary caregivers reported more negative lifestyle changes than secondary caregivers. Further studies are needed to investigate needs and burden experienced by caregivers of sABI patients during the postacute rehabilitation phase, also in relation to the patients' outcome, to address support interventions for them and improve their quality of life.

Secondary Brain Injury: A Concept Analysis.

BACKGROUND: Traumatic brain injury and cerebrovascular disease may lead to motor, behavioral, and/or cognitive disabilities. The associated neurologic and vascular damage triggers a chain of events that lead to a secondary brain injury (SBI), a preventable cause of adverse neurological outcomes. Proper prevention of these factors may limit undesirable outcomes. This article presents a concept analysis that aims to form a single definition of the term secondary brain injury for nursing personnel. METHODOLOGY: Concept analysis was used to clarify the concept of SBI. An electronic search was performed on existing nursing literature dating from 1995 to 2016 on PubMed, MEDLINE, Ovid Journal, Wiley, and ProQuest. RESULTS: A clear definition and description of the attributes, antecedents, and consequences of SBI increases the knowledge and level of recognition of the secondary injuries. This may lead to strategies that reduce the risk of long-term effects (disability) and poor clinical outcomes. CONCLUSIONS: This concept analysis contributes to the endeavor of identifying phenomena that are pertinent for nursing; it also provides a basis for future research that leads to improving nursing interventions and creating educational programs and healthcare policies that prevent or eliminate the consequences of SBI.

Multimodal Neuromonitoring in Neurocritical Care.

Neuromonitoring is important for patients with acute brain injury. The bedside neurologic examination is standard for neurologic monitoring; however, a clinical examination may not reliably detect subtle changes in intracranial physiology. Changes found during neurologic examinations are often late signs. The assessment of multiple physiological variables in real time can provide new clinical insights into treatment decisions. No single monitoring modality is ideal for all patients. Simultaneous assessment of cerebral hemodynamics, oxygenation, and metabolism, such as in multimodal monitoring, allows an innovative approach to individualized patient care.

Emotional Labour of Caregivers Confronted With Aggressive Brain-injured Patients.

BACKGROUND: Aggressive behaviours are common with people who have suffered brain injuries and induce difficult emotions among certified nursing assistants and medical-psychological assistants who take care of them. These caregivers carry out emotional labour whose content and strategies are little known. AIM: The study explores the emotional labour of certified nursing assistants and medical-psychological assistants faced with the aggressive behaviours of brain-injured patients. METHODS: Semi-structured interviews were conducted with 37 caregivers. Interviews were analysed via a thematic content analysis. RESULTS: The analysis shows that the emotional labour of caregivers varies in accordance with the state of "consciousness" or "non-consciousness" that they attribute to the brain-injured patient with regard to this aggressive behaviour. This is a deep acting strategy. Moreover, caregivers shut off their emotions in order not to transmit them to the patient. This surface acting has the first objective for the caregiver of maintaining control of the situation and a second objective of protecting the patient emotionally and therefore of being perceived as a "good" caregiver. Emotional labour also meets a need to preserve the professional self-image and professional status negatively affected in the interaction with the aggressive brain-injured patient. CONCLUSIONS: Our study specifies the different strategies of the emotional labour of caregivers and their circumstances of use when they are confronted with aggressive behaviour by brain-injured patients. Targeted support for this emotional labour, such as training and practical analysis, is essential for the development of care practices promoting a caring relationship.

Increasing Adherence to Brain Trauma Foundation Guidelines for Hospital Care of Patients With Traumatic Brain Injury.

BACKGROUND: The Brain Trauma Foundation has developed treatment guidelines for the care of patients with acute traumatic brain injury. The Adam Williams Initiative is a program established to provide education and resources to encourage hospitals across the United States to incorporate the guidelines into practice. OBJECTIVE: To explore the relationship in hospitals between participation in the Adam Williams Initiative and adherence to the Brain Trauma Foundation guidelines for patients with acute traumatic brain injury. METHOD: Hospitals that participated in the Adam Williams Initiative entered data into an online tracking system of patients with traumatic brain injury for at least 2 years after the initial site training. Data included baseline hospital records and daily records on hospital care of patients with traumatic brain injury, including blood pressure, intracranial pressure, cerebral perfusion pressure, oxygenation, and other data relevant to the 15 key metrics in the Brain Trauma Foundation guidelines. RESULTS: The 16 hospitals funded by the Adam Williams Initiative had good overall adherence to the 15 key metrics of the recommendations detailed in the Brain Trauma Foundation guidelines. Variability in results was primarily due to data collection methods and analysis. CONCLUSIONS: The Adam Williams Initiative helps promote adherence to the Brain Trauma Foundation guidelines for hospital care of patients with traumatic brain injury by providing a platform for developing and standardizing best practices. Participation in the initiative is associated with high adherence to clinical guidelines, a situation that may subsequently improve care and outcomes for patients with traumatic brain injury.

Caregivers' lived experience in trying to read slight movements in a child with severe brain injury: A phenomenological study.

AIMS AND OBJECTIVES: To explore caregivers' lived experience of reading slight movements of a child with severe brain injury. BACKGROUND: Despite increased need, the development of individual care for children with severe brain injuries has been prevented by their severe physical state and the poor reproducibility of their movements. In addition to a lack of evidence on the motor characteristics of patients with severe brain injury with multiple disabilities, their own development contributes to increasing variability in their states. Thus, caregivers are compelled to rely on their experiences, which have not been academically explored. DESIGN: A qualitative study based on van Manen's method of hermeneutic phenomenology. METHODS: Data were obtained through twenty-one 3-hr observation sessions and five 15- to 45-min group interviews. We observed a child (called AK) with severe brain injury and his 61 caregivers, and conducted group interviews with 28 caregivers. We focused on caregivers' experiences of reading AK's slight movements. The data were interpreted based on van Manen's hermeneutic phenomenological approach. RESULTS: Four themes emerged as caregivers' experience in trying to read AK's slight movements. By considering "AK's physical state and his slight movements" and discovering "caregivers' 'sense of uncertainty' about AK's slight movements," caregivers could decipher "AK's multiple slight movements." "Sharing" was found as a necessary aspect of these other three themes of reading AK's slight movements. CONCLUSIONS: We presented caregivers' experiences as related to these four themes in their efforts to read the slight movements of AK. Due to AK's slight movements with poor reproducibility, "sharing" was necessary to read AK's slight movements, as it exposes caregivers' lived experience to the interpretation of multiple caregivers. RELEVANCE TO CLINICAL PRACTICE: These four themes may be useful for assessing, guiding and promoting caregivers' use of sharing when reading the slight movements of children with severe brain injury.
