A variety of educational interventions may have an impact on patient assessment and patient outcome. Studies have reported an inconsistency in the use of Neurological assessments performed by nurses, such as the Glasgow Coma Scale (GCS) in the acute care setting. The aim of this study is to evaluate the impact of an educational intervention for nurses on the number of performed neurological assessments over time.
Intervention: A total of 60 health care staff was offered education on neurological assessment (GCS) of Pediatric Intensive Care Unit (PICU) at a level one-trauma center.
Methods: A quasi-experimental design to evaluate the change in the number of performed neurological assessments in children. The amount of GCS assessments was compared before and after the educational intervention.
Findings: The educational intervention showed a significant increase in GCS assessments during the one and two-month periods after the intervention but with a decline at three months post-intervention.
Continuing educational, Interventions, Outcome, Nursing, Critical Care
Studies have shown that a variety of educational interventions may have an impact on patient assessment and patient outcome; however, the majority has been results from medical education of residents [1,2]. To my knowledge, only a few studies describing Continuing Medical Education (CME) for nurses in the clinical setting and there is a shortage of evidence for it's effectiveness and efficacy [3,4]. The rapid development of both medical and technical techniques in critical care during recent years has placed a high demand on the personal ability of health care staff to collect and analyze important information at the right time. This high demand on a personal level makes the planning of educational interventions even more important if the learning is to be successful, effective and improve patient outcome. In the acute care setting the ability to identify patients in need of acute interventions is essential. To facilitate the early detection of complications during care, health care professionals use a variety of assessment tools. For patients with a traumatic brain injury, the assessment of conscious level is crucial, and the primary tool is the Glasgow Coma Scale (GCS) [5,6]. The ultimate goal in the use of GCS is to identify those in need of acute intervention as early as possible and thus prevent secondary brain injuries , thereby reducing both mortality and morbidity among patients. From a clinical and educational point of view, all healthcare professionals working in emergency care should use assessment of conscious level as easily as other routine observations of vital signs . However, several studies have reported an inconsistency in the use of GCS in the clinical setting, and it is recognized that education and training is required to ensure that the tool is used as a valid indicator of patient status .
Reports on interventions concerning continued education for nurses working in critical care areas show support for different implementation approaches, but they lack descriptions of theoretical and educational considerations . In the clinical setting the need for an educational intervention concerning the assessment of GCS has been expressed and the lack of studies of successful educational interventions for nursing in the critical care area shows the need for further studies.
The educational session was planned with an objective goal (to improve the frequency of neurological assessment) but also with the adult learning theory  in mind. The theory is based on the assumption that learning occurs when learners decide what they need to learn; it is not based on the teacher's view of what the learners need to know. Adult learning assumptions are:
• Adults prefer learner-centered learning, which provides greater control and autonomy in the learning process.
• Adult learning is rooted in the acquisition of learning skills and the use of a reflective process
• Experience is the core of adult learning
• Adults value learning that helps them deal with real-life situations
To achieve learning the learner is treated as an independent and self-directed learner, which includes taking into account the health care professionals' own educational needs, providing a comfortable climate for learning, and involving learners in the planning of the session .
Therefore, the aim of this study was to evaluate educational interventions based on adult learning theory in the critical care setting and their impact on the frequency of neurological assessment over time.
Quasi-experimental, using one group, with before and after measurements performed to evaluate changes in performed neurological assessment in children cared for in a PICU.
A total of 60 health care staff (Reg.nurses n=30 and nurses aids n=30.) with theoretical knowledge and experience (range: 1-30 years) from critical care was offered education on neurological assessment of children in the PICU at a level one-trauma center. The PICU had eight beds and cared for children (0-18 years) with both medical and surgical conditions. The educational intervention was performed on three occasions during November 2012. All health care staff had taken an introduction course during the first year of employment, consisting of neurological assessment of children and clinical experience of care of children requiring intensive care.
The educational session included one seminar lasting 1.5 hours on three occasions which was planned by the author. The author, with a pedagogical education and with clinical experience of critical care, conducted all sessions. The purpose of the session was to define neurological assessment (the how, when and why) for educated nursing staff in critical care with basic knowledge in neurological disorders in children and the regular assessment of vital signs, describe the role of the GCS and provide evidence to support the importance of detecting early signs of change in neurological performance. The educational intervention was planned with an adult learning theory, which included taking account of the health care professionals' own educational needs based in their knowledge and experience from critical care. This was evaluated at the beginning of each session by asking the staff what they wanted and needed to know in relation to neurological assessment; creating a comfortable learning climate and engaging in a dialog with the participants which involved the learners in the planning of the session; encouraging the learners to formulate their own learning goals in writing; and using actual cases from the clinical setting to visualize the learning objectives [1,11]. All this required a flexible teaching role with the focus on the participant's demands and not on the teacher's own specialized knowledge.
Data from the registry system of patient care at the PICU concerning the amount of assessments of GCS was collected in retrospect and entered into an Excel database. Descriptive statistics was analyzed (numbers and per cent). The demographic variables, such as the number of patients and their diagnoses, were collected to verify that the frequencies were not dependent on the number of patients or their diagnosis using a T-test. A p-value < 0.005 was considered statistically significant. To analyze the impact of the educational intervention a before measure (Pearson Chi-Square for nominal variables) of the frequencies (n, %) of performed neurological assessment during the month of October compared to November, December and January was performed. All analysis was conducted using IBM SPSS version 20.0.
Ethical approval was not obtained since no personal information was collected from individual health care personnel and the study was considered to measure quality of care. Therefore, the local ethical committee would not consider the application for ethical approval. The manager of the ward approved the study.
A total of 60 health care staff participated in the educational intervention. Our result showed a significant (Chi-square= 64.56, df=2, p=< 0.001) increase in assessments during the one and two-month periods after the intervention (Figure 1).
Figure 1: Number of patients vs. number of patients with more than one registration View Figure 1
There was also a significant increase in the total number of registrations/patient and was not dependent on the number of patients or the diagnosis of the patient (Figure 2).
Figure 2: Total number of registrations vs. number of patients View Figure 2
The result shows an increase of registrations of GCS during the first two months but a decline after three months (Figure 3).

The result shows a positive result of an educational intervention for nurses aimed to increase the frequency of neurological assessment (GCS) in children receiving critical care.
The significant change in nursing behavior could be a result of the educational session planned with adult learning theories in mind as well as several teaching approaches during the educational session. The result is well in line with the result described by Bloom  who states that combining teaching techniques for physicians such as: interactive education, audit and feedback, reminders, clinical practice guidelines and using opinion leaders all show a positive effect on medical care and patient outcome. This positive result could also be a result of both improved knowledge concerning the assessment of GCS and its value for patient care, or the fact that the participants' own experience was included in the session.
However, the health care professionals, especially in the critical care unit, who sometimes have an intense workload, need feedback on their assessments to sustain a change in behavior. This result is well in line with the result of Howell et al.  and Flodgren et al.  that also showed a decline in a positive change three months post-education. With this in mind, not only knowledge but also changes in behavior could result from educational interventions, but more than one intervention is needed to further develop sustainable change, even after an intervention using adult learning theories. As described by Davies et al.  and Bloom  studies concerning outcome after CME has to consider: different practitioners, hospital settings and behaviors to understand the full effect of an educational intervention. The rapid development of both medical and technical techniques during care and especially in critical care puts high demand on both organizations and the individual health care professionals to continuously develop clinical skills to improve the quality of patient care. As discussed by Bloom  it is clear that the least-effective education methods in the clinical setting are didactic lectures and distributing printed materials alone. How clinical education should be performed in the future should be in focus for research and quality improvement programs so that educational interventions are evaluated with the right outcome.
There are several limitations to this study. To evaluate the impact on patient care i.e. improved outcome measured by mortality and morbidity rates, this study should have been evaluated using a long-term follow-up, which was not possible during this time period. Due to the fact that there is a small incidence (four per cent as reported by Snoek et al.  of neurological deterioration after a brain injury, the impact of measuring GCS has to be measured over several years for a valid result.
The small sample and the short period of evaluation time could have had an impact on the result. To further study the impact of using adult learning theories, several teachers/facilitators and several clinical settings should be compared.
Educational interventions using adult learning theories are well suited to promote learning in the clinical setting in order to encourage changes in nursing behavior. To achieve sustainable change in behavior, repeated feedback is necessary; therefore when planning an educational intervention continued feedback should also be prearranged.
