Neuroscience intensive care unit nurses carry numerous interventions when caring for a critically ill traumatic brain injured patient. In this study, their specific interventions, that they routinely perform, are identified. Quantitatively and qualitatively, nurses regularly monitor hemodynamic considerations such as O2 saturation, BP and temperature and other physiological parameters, monitor intracranial pressure and cerebral perfusion, and providing emotional support. While qualitative analyses solely showed that the other nursing interventions that they do could be classified as neurophysiological interventions, psychosocial interventions, injury prevention interventions, and interventions that maintains therapeutic environment. This study would present proofs of the comprehensive role of the neuroscience intensive care unit nurses caring for Traumatic Brain Injured patients and can be used in future researchers that would like to investigate the contribution of neuroscience intensive care unit nurses’ interventions to the progression of the patient’s condition.Nursing Interventions For Critically Ill Brain Injury Patients Essay

After gaining an approval from the institutional review boards and nursing administration, a survey was done to 67 nurses who work in 3 different ICUs from two level-I trauma centers who regularly care for critically ill TBI patients. Those two trauma centers were chosen because they were both comparable in terms of delivery and organization of nursing care, employment ratios, and nurse characteristics so as to not have bias on the study. The respondents were registered nurses that worked for at least 3 months as a full-time or part-time clinical bedside nurse in an ICU that handles critically ill Traumatic Brain Injured patients. They were approached during their unit staff meetings and change-of-shift report times and invited to take part in the study. They were then given a questionnaire which was comprised of 3 parts: Part A was comprised of series of questions about their previously handled TBI patient, part B contained case scenarios wherein they used nursing judgments, and part C gathered demographic information about the nurse respondents.Nursing Interventions For Critically Ill Brain Injury Patients Essay

For the quantitative data, all neuroscience intensive care unit nurses indicated that they were responsible for the monitoring of the patient’s blood pressure, oxygen saturation, and temperature. And approximately 50% of the nurses indicated that they were also responsible for the monitoring of the ICP and CPP. For the qualitative data, there were 4 categories where in the nurse’s interventions were grouped. The first one is the Neurophysiological Interventions. It is comprised of monitoring and maintaining the physiological parameters to guarantee neurological stability in TBI patients. In addition to that parameter, they also monitored pulmonary artery and central venous pressure reading, cerebral spinal fluid drainage, serial laboratory values, and carbon dioxide parameters. Keeping these values within the normal range, nurses help TBI patient to prevent secondary brain injury and to uphold neurological stability. The second one is the Psychosocial Interventions. In this category, nurses make meetings between the family member and various members of the healthcare team. Meetings between the family members are held to provide education and background of the plan of care being rendered to the patients and also to give information about the possible patient outcomes and rationales for the therapies. The third one is the Injury Prevention Interventions. This category aims to prevent additional complications to the patient and to ensure patient’s safety. The primary interventions for this category are maintenance of spine precautions and frequent reorientation of the patient. Other interventions like prevention of skin breakdown and ventilator-associated pneumonia, prevention of falls and evaluation for the need of restraints to prevent disruption of medical devices are considered usual care for any vitally ill patient. The fourth and the last category is Maintaining Therapeutic Milieu. In this category, nurses give suitable environment for the patient and provide their special needs. Limiting visitors, decreasing lighting, minimizing noise, avoiding disruption of the patient’s sleep-wake cycle are the interventions done in this group. All of which are carried out to provide optimal care and rest periods to the patient thus limits further increase in ICP.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Neuroscience nurses indeed have an essential part in the care of the critically ill traumatic brain injured patients. Their interventions address the prevention of secondary brain injury and complications and provide significant support and guidance for the family members. Therefore, they have a big contribution to the patient’s positive outcomes, but there is still no research documenting their multifaceted role on the patient’s progression. These data are needed to recognize the exceptional contribution of neuroscience ICU nurses as part of the interdisciplinary team caring for TBI patients and as a foundation for future research investigating how ICU nurses impact patient and family recovery from TBI during the acute stage of injury.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Neuroscience intensive care unit (ICU) nurses deliver a number of interventions when caring for critically ill traumatic brain injury (TBI) patients. Yet, there is little research evidence documenting specific nursing interventions performed. As part of a larger study investigating ICU nurse judgments about secondary brain injury, ICU nurses were asked to identify interventions routinely performed when caring for TBI patients. Quantitative and qualitative analyses indicate that all nurses routinely monitored hemodynamic parameters such as oxygen saturation, blood pressure, and temperature. Nurses were responsible for monitoring intracranial pressure and cerebral perfusion pressure approximately 50% of the time. Qualitative analyses revealed that additional nursing interventions could be categorized as neurophysiological interventions, psychosocial interventions, injury prevention interventions, and interventions to maintain a therapeutic milieu. Findings from this study provide evidence of the multifaceted role of the neuroscience ICU nurse caring for TBI patients and can be used in future research investigating the impact of nursing interventions on patient outcomes.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Traumatic brain injuries (TBIs) account for over 200,000 hospital admissions every year in the United States, costing over 3.2 billion healthcare dollars annually (Langlois, Rutland-Brown, & Thomas, 2006; Russo & Steiner, 2007). It is estimated that 71% of TBI hospitalizations are for patients with severe injuries necessitating critical care monitoring (Russo & Steiner, 2007). Neuroscience intensive care unit (ICU) nurses deliver a myriad of interventions when caring for these critically ill TBI patients. Yet, there is little research evidence documenting specific interventions performed. This information is needed to highlight the autonomy and role of the neuroscience ICU nurse when caring for critically ill TBI patients and as a basis for future research investigating how nursing interventions impact patient outcomes. Therefore, the purpose of this article was to present findings from a research study in which neuroscience ICU nurses described interventions routinely performed when caring for TBI patients.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Descriptions of Nursing Interventions
Several reports identify nursing interventions for critically ill TBI patients. Although these reports are not based on research evidence, they do provide general descriptions of ICU nurse responsibilities when caring for TBI and other neurologically impaired patients (Ladanyi & Elliot, 2008; Littlejohns & Bader, 2009; Olson & Graffagnino, 2005; Presciutti, 2006; Wong, 2000). Responsibilities include monitoring patient physiological parameters and ensuring hemodynamic stability, performing serial neurological examinations, preventing secondary injury, and providing emotional support for patients and families (Chamberlain, 1998; Olson & Graffagnino, 2005; Presciutti, 2006). More recently, ICU nurses are involved with advanced technologies, such as monitoring and maintenance of brain tissue oxygenation and monitoring electroencephalograph and bispectral index readings (Albano, Comandante & Nolan, 2005; Bader, Littlejohns, & March, 2003; Littlejohns & Bader, 2009). Collectively, these described interventions comprise the multifaceted role of nurses caring for TBI patients in the ICU, where technical and interpersonal competencies are crucial.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Nursing Priorities of Care
The interventions described earlier are often guided by nursing priorities that have been identified in the research literature (Fonteyn & Fisher, 1994; Villanueva, 1999). Two qualitative studies specifically describe nursing priorities and associated interventions when caring for critically ill neurologically impaired patients. A key priority when caring for unconscious patients is “giving the patient a chance,” in which interventions center on learning about the patient, maintaining and monitoring patient status, talking to the patient, and working with the family (Villanueva, 1999).

In a separate study, nurse priorities when caring for postoperative craniotomy patients are the following: (a) The patient will become responsive and (b) the patient will remain hemodynamically stable (Fonteyn & Fisher, 1994). Nursing interventions related to these priorities include assessments of patients’ level of consciousness or neurological status, blood pressure (BP), breath sounds, temperature, amount of respiratory secretions, central venous pressure, heart rate and rhythm, pulse pressure, and arterial blood gases. These studies contribute information about nursing priorities guiding interventions for neurologically impaired patients in the ICU. However, findings from these studies are limited by small sample sizes (n = 16 and n = 3, respectively), and interventions described are not specific to the complex care often required for critically ill TBI patients.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Factors Influencing Nurse Interventions
The presence of external factors can influence nursing interventions performed with neurologically impaired patients (Cook, Deeny, & Thompson, 2004; McNett, 2009; McNett, Doheny, Sedlak & Ludwick, 2009). Nursing judgments about appropriate interventions when managing secondary brain injury in critically ill TBI patients are influenced by worsening values for oxygen saturation, intracranial pressure (ICP), cerebral perfusion pressure (CPP), and nursing shift. Nurses are less likely to rely solely on nursing interventions and more likely to consult another member of the healthcare team as values for oxygen saturation, ICP, and CPP fall farther from recommended parameters. In addition, nurses working day shift are more likely to rely solely on nursing interventions and less likely to consult other healthcare team members than are their night shift colleagues (McNett, 2009).Nursing Interventions For Critically Ill Brain Injury Patients Essay

When managing subarachnoid hemorrhage, neuroscience ICU nurses are influenced by knowledge of current standards and therapies for fluid and hydration management. Judgments about interventions center on the nursing process of assessment, planning, implementation, and evaluation. Using this process, nurses rely on patient cues, such as physical appearance, recorded intake-output, and neurological status when determining need for interventions (Neal & Deeny, 2004). When managing fever in neurologically impaired patients, nurses describe decisions about interventions being influenced by the individual nurse, the patient, and the barriers present within the organization or nursing unit (Thompson, Kirkness & Mitchell, 2007).Nursing Interventions For Critically Ill Brain Injury Patients Essay

The studies mentioned contribute information about nursing priorities and factors influencing nurse interventions for neurologically impaired patients. However, there is no research evidence documenting specific interventions performed by ICU nurses when caring for critically ill TBI patients. The purpose of this article therefore was to present findings from a research study in which neuroscience ICU nurses reported routine interventions administered when caring for TBI patients.

Methods
Procedures
The findings presented here are part of a larger study investigating ICU nurse judgments about secondary brain injury using a prospective factorial survey research design (McNett, 2009; McNett et al., 2009). Approval for the study was obtained from the institutional review boards and nursing administration at both study sites. An anonymous survey was administered to 67 nurses working in three ICUs from two level I trauma centers who routinely care for critically ill TBI patients. Both study sites were designated as level I trauma centers by the American College of Surgeons and were classified as large teaching hospitals. Both were similar in terms of delivery and structure of nursing care, staffing ratios, and nurse characteristics. Study site A had a larger trauma volume, admitting approximately 3,000 trauma patients per year, whereas study site B averaged 1,000 trauma admissions annually. Study site A had recently identified the Guidelines for the Management of Severe Traumatic Brain Injury (Brain Trauma Foundation, American Association of Neurological Surgeons, The Joint Section on Neurotrauma of Critical Care, 2007) as a reference to guide care of the critically ill TBI patient in their ICUs. However, there were no standing order sets or standardized care plans in place for critically ill TBI patients at either study siteNursing Interventions For Critically Ill Brain Injury Patients Essay.

Nurses from both sites were invited to participate in the study if they held an active state license as a registered nurse; were employed full-time, part-time, or per diem as a clinical bedside nurse in an ICU that admits critically ill TBI patients; and were employed in the current ICU for a minimum of 3 months. Nurses were excluded if they did not have experience caring for critically ill TBI patients, were currently in nursing orientation, or were not directly responsible for the continuous bedside monitoring and delivery of care to critically ill TBI patients in that ICU. A power analysis indicated that a sample size of 60 would be sufficient to detect a medium small effect size of .20 with a power of .80.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Nurses in the ICU were approached during unit staff meetings and change-of-shift report times and invited to participate in the study. The study survey had three parts: Part A contained a series of questions about the last TBI patient nurses cared for in their unit and interventions typically performed when caring for these patients, part B contained case scenarios in which nurses were asked to indicate judgments they were most likely to make, and part C gathered demographic information about nurse respondents. Findings from the latter two survey sections have been previously reported (McNett, 2009). In this article, findings from survey part A (nurse interventions) are presented.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Part A of the study survey contained six fixed-response questions about the last TBI patient nurses cared for in their ICU. Nurses were asked how long ago they took care of a TBI patient, which physiological parameters they were responsible for managing, and the patient’s mechanism of injury, age, gender, and comorbidities. Content for these questions was derived from an extensive review of the literature describing various nursing interventions and was validated by a team of clinical nurses and two clinical nurse specialists who routinely care for critically ill TBI patients. A final open-ended question on the study survey asked nurses to identify using free-text responses what interventions they performed when caring for this patient.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Data Analysis
Descriptive analyses, including means, standard deviations, and frequencies, were performed, with the quantitative data gathered from the fixed-response questions on the study survey. Methods for qualitative data analyses outlined by Pope and Mays (1999) were then performed with the free-text responses nurses provided. All free-text responses were recorded and systematically reviewed using first-level coding to identify recurring phrases and commonalities among responses. The constant comparison method was used to ensure that the identified codes were inclusive of all data. These first-level codes were then reviewed and grouped into larger categories using second-level coding, which described the types of interventions performed by nurses. The recorded data, initial codes, and overall themes were reviewed by a second investigator with extensive neurocritical care experience to validate the findings.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Results
Study Sample
Table 1 presents a summary of the characteristics of nurse respondents. A total of 67 nurses returned completed surveys, yielding a 44% response rate. Most nurses in the study were between the ages of 26 and 40 years (64%), Caucasian (92.4%), and women (76.1%). Many nurses had less than 10 years of experience working in the ICU (70.1%) and caring for TBI patients (74.6%). Over half of the nurses (58%) held bachelor degrees, and primary shifts included days (25.4%), day-night rotating (29.9%), day-evening rotating (10.4%), evenings (1.5%), and nights (32.8%).Nursing Interventions For Critically Ill Brain Injury Patients Essay

Quantitative Data
Descriptive analyses were used to analyze the first six questions on the study survey. ICU nurses were asked to indicate how long ago they last cared for a TBI patient in their unit and which physiological parameters they were responsible for managing and to identify the patient’s mechanism of injury, gender, age, and comorbidities. Table 2 provides a summary of ICU nurse responses.

Table 2 – Click to enlarge in new window TABLE 2. Characteristics of Most Recent TBI Patient
All ICU nurses had cared for a critically ill TBI patient either within the last week (65.7%) or month (34.3%). ICU nurses indicated that they were responsible for monitoring BP, oxygen saturation, and temperature among all of these recent patients. Approximately 50% of nurses indicated that they were also responsible for monitoring ICP and CPP. Most nurses described their most recent TBI patients as male patients (85%), between the ages of 36 and 65 years (55.2%), and being injured from a motor vehicle crash (46.3%). Over 60% of patients recently cared for by nurses had also experienced extracranial injuries requiring additional nursing care, and smaller percentages of patients had other comorbidities, such as hypertension (34.3%) or diabetes (14.9%).Nursing Interventions For Critically Ill Brain Injury Patients Essay

Qualitative Data
Nurses in the ICU were then asked to identify additional nursing interventions performed when caring for their most recent TBI patient. Qualitative analyses of these responses indicated that interventions could be grouped into four categories: neurophysiological interventions, psychosocial interventions, injury prevention interventions, and interventions to maintain therapeutic milieu. Figure 1 displays each category and the corresponding interventions reported by nurses.

Figure 1 – Click to enlarge in new window FIGURE 1. Nurse Interventions for Critically Ill Traumatic Brain Injury Patient
Neurophysiological Interventions
Nurses in the ICU reported being responsible for monitoring and maintaining various physiological parameters to ensure neurological stability in patients. Consistent with their responses to the quantitative questions, nurses described monitoring patient oxygen saturation, BP, ICP, CPP, and temperature. In addition to these parameters, nurses also monitored pulmonary artery and central venous pressure readings, cerebral spinal fluid drainage, serial laboratory values, and carbon dioxide parameters. By keeping these values within acceptable limits, nurses were preventing secondary brain injury and promoting neurological stability. Additional interventions to monitor neurological stability included performing neurological assessments at a minimum of every hour and transporting and monitoring patients for computed axial tomography scan and magnetic resonance imaging testing. Several nurses also cited assisting with brain death examinations and preparing patients for organ donation as other interventions.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Within this category of neurophysiological interventions, nurses provided evidence of specific interventions performed to ensure that the mentioned physiological parameters remained within normal limits. To obtain acceptable values for oxygen saturation, nurses cited being responsible for ventilator management and suctioning. To keep BP, ICP, and CPP within normal limits, nurses administered medications such as mannitol, propofol, and narcotics and kept the patient’s head of bed elevated and neck in a midline position. Nurses also administered blood products and closely monitored intake-output to ensure adequate circulating blood volume, thus promoting cerebral perfusion.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Psychosocial Interventions
Nurses in the ICU described delivering a variety of interventions that were psychosocial in nature. Interventions in this category involved coordinating meetings and communication between family members and various members of the healthcare team, both in the acute (i.e., coordinating with physicians or organ donation teams) and long-term plans of care (i.e., coordinating with case management, social work). ICU nurses also provided education to family members about the plan of care, possible patient outcomes, and rationale for current therapies. Finally, nurses described simply serving as a source of support for family members by listening and providing necessary reassurance.

Injury Prevention Interventions
The third type of interventions reported by nurses included those aimed at preventing additional patient complications and ensuring patient safety. Within this category, some interventions were specific to TBI patients, such as maintaining spine precautions and frequently reorienting patients. Other interventions were considered routine care for any critically ill patient. These included frequent turning and repositioning of patients to prevent complications of immobility, such as skin breakdown and ventilator-associated pneumonia. ICU nurses also reported ensuring patient safety by preventing falls and determining the need for and monitoring restraint use to prevent disruption of medical devices. All interventions in this category were delivered to ensure a safe environment for patients and to prevent further injury.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Maintaining Therapeutic Milieu
The final category of interventions reported by nurses included those performed to maintain a therapeutic environment for the critically ill TBI patient. These interventions included intangible care given by nurses considering the special needs of TBI patients. Specifically, nurses reported working to limit environmental stimuli for patients. Interventions included regulating visitors, decreasing lighting, and minimizing noise. Many nurses also cited spacing nursing activities to allow for adequate rest periods and to limit increases in ICP.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Discussion
Neuroscience ICU nurses have an integral role in the care of the critically ill TBI patient. Interventions routinely performed prevent secondary brain injury and patient complications and provide the necessary support and guidance for family members. Yet, there is no research documenting specific interventions associated with this multifaceted role, neither is there data indicating positive outcomes associated with these nursing interventions. These data are needed to acknowledge the unique contribution of ICU nurses as part of the interdisciplinary team caring for TBI patients and as a basis for future research investigating how ICU nurses impact patient and family recovery from TBI during the acute stage of injury.Nursing Interventions For Critically Ill Brain Injury Patients Essay

Findings from this study support the anecdotal descriptions of ICU nurse responsibilities when caring for neurologically impaired patients (Chamberlain, 1998; Ladanyi & Elliot, 2008; Littlejohns & Bader, 2009; Presciutti, 2006). The four categories of interventions described indicate that neuroscience ICU nurses must possess extensive knowledge of the pathophysiological processes associated with primary and secondary brain injury. Nurses must also have the technical skills to effectively manage these processes and ensure neurological stability. Finally, excellent interpersonal skills are crucial to communicate with families and other members of the healthcare team.Nursing Interventions For Critically Ill Brain Injury Patients Essay

When examining the interventions reported by nurses, it is interesting to note that most interventions were classified as neurophysiological, which centered on ensuring the neurological and physiological stability of the patient. This finding is supported by findings from the larger study in which the physiological parameters, specifically a patient’s oxygen saturation, ICP, and CPP, were the most significant variables influencing ICU nurse judgments when caring for TBI patients (McNett et al., 2009). This is consistent with smaller qualitative studies concluding that maintenance of physiological and neurological parameters is a priority when caring for neurologically impaired patients (Fonteyn & Fisher, 2004; Villanueva, 1999). Thus, although the ICU nurse caring for critically ill TBI patients is responsible for a number of interventions, it does appear that stabilizing the patient’s physiological parameters and neurological status is the key priority. This certainly is of utmost importance because these factors ultimately are what influence patient mortality and outcome.Nursing Interventions For Critically Ill Brain Injury Patients Essay

The study is limited by the fact that data were only gathered from two study sites in one geographical location. As a result, findings may not be generalizable to all neuroscience ICU nurses. In addition, nurses in this study were asked to recall interventions they performed with previous TBI patients and therefore may not remember all interventions delivered when caring for that patient. It is likely that additional interventions were done but not necessarily reported by the nurses in the study. Despite these limitations, findings do provide baseline evidence of specific interventions of ICU nurses. This information is necessary for future research investigating the impact of these interventions on outcomes.Nursing Interventions For Critically Ill Brain Injury Patients Essay
