Under pressure: preventing pressure ulcers in critically ill infants.

PURPOSE: To determine whether a pressure ulcer prevention bundle was associated with a significant reduction in pressure ulcer development in infants in the pediatric intensive care unit. DESIGN AND METHODS: Quasi-experimental design involving 399 infants 0 to 3 months of age at a large tertiary care medical center. RESULTS: The implementation of the care bundle was associated with a significant drop in pressure ulcer incidence from 18.8 to 6.8%. PRACTICE IMPLICATIONS: Pressure ulcers can be prevented in the most vulnerable patients with the consistent implementation of evidence-based interventions and system supports to assist nurses with the change in practice.

Integrative review: parent perspectives on care of their child at the end of life.

This integrative review aims to describe parents' perspectives on end-of-life care for their children. Fifteen publications from a literature search of the Cochrane databases, CINAHL, MEDLINE, and PSYCHinfo were included in the review. Recurring themes included poor communication/lack of information, strained relationships/inadequate emotional support, parental need to maintain parent/child relationships in life and death, quality of care continues after the death of the child, influence of services/planning on parent/child impacts quality of life, and the difficult decision to terminate life support. No studies were identified that focused on parents' perspectives on the care their child received at the end of life. Further research that focuses on the special needs of parents at this difficult time is needed.

Impact of self-hypnosis in women on select physiologic and psychological parameters.

OBJECTIVE: To examine physiologic and psychologic effects of hypnosis in healthy women. DESIGN: Quasi-experimental, within-subject, repeated measures. SETTING: Private laboratory setting in an urban Midwestern College of Nursing. PARTICIPANTS: Convenience sample of 30 healthy, female volunteers who were nonpregnant, predominantly White, college students. METHOD: Participants listened to a 30-minute recording of relaxing, affirming hypnotic suggestions while sitting comfortably in a recliner. Hypnotizability and trait anxiety were measured at baseline. Tension-anxiety was measured at baseline and following the hypnotic induction. Heart rate, respiratory rate, and heart rate variability were collected before, during, and following the hypnotic experience. RESULTS: Paired t tests revealed significantly reduced heart rate (p<.001), respiratory rate (p<.001), low-to-high frequency heart rate variability ratio (p<.001), and tension-anxiety (p<.001), whereas high frequency heart rate variability was increased (p<.001) after the 30-minute hypnotic session. CONCLUSIONS: Hypnosis is an innovative, low-technology, self-modulated approach that may contribute to stress reduction and health promotion. Parameters demonstrated increased parasympathetic nervous system activity associated with relaxation during and immediately after the hypnosis experience. Findings from this study suggest that nurses can include hypnosis information when advising healthy women about available stress reduction approaches, as well as tailor their nursing care for women who present using this alternative approach.

Pilot study investigating infant vagal reactivity and visual behavior during object perception.

OBJECTIVE: The authors examined whether changes in vagal tone were related to infant visual attention during auditory and visual events paired (synchronous) and not paired (asynchronous) in time. They predicted that infants would demonstrate greater visual attention to the synchronous slideshow and that vagal tone would decrease with visual attention. METHOD: Nineteen infants, 3.5 months old, watched computer-generated synchronous or asynchronous slideshows of auditory and visual stimuli. Visual behavior and vagal tone data were collected. Vagal tone reflects physiological responses during attention or exposure to mild stressors. Repeated-measures analysis of variance examined differences in vagal tone across conditions. RESULTS: Visual behavior did not differ between the synchronous and asynchronous slideshow conditions. Vagal tone was significantly lower during the asynchronous slideshow. CONCLUSION: Infants may discriminate synchronous from asynchronous stimuli without changing visual behavior. Implications related to play with toys or objects are discussed.

Videoconferencing and telehealth technologies can provide a reliable approach to remote assessment and teaching without compromising quality.

Cardiovascular disease remains a significant chronic healthcare problem in this country, with considerable associated economic and quality-of-life challenges. Along with these challenges, there is high demand for healthcare provider time, particularly in the areas of management of complex healthcare needs and patient education. At the same time, a critical nursing shortage exists. Telehealth technologies provide opportunities to meet the rapidly growing needs of consumers and healthcare practitioners. Many in need of services have limited access to high-end technologies. An argument has been made that the lowest level of technology needed to carry out a task should be used, if it is capable of providing the necessary services. Videoconferencing capabilities allow healthcare practitioners to engage in virtual face-to-face encounters with patients or other healthcare providers. A variety of levels of sophistication in these videoconferencing systems are available. In an effort to evaluate the effectiveness and consumer satisfaction with videoconferencing, 3 pilot studies were conducted to compare face-to-face, low-bandwidth, and high-bandwidth approaches to performing common assessments and patient education activities. In one study, a variety of experienced healthcare practitioners performed functional assessments of stroke subjects using a collection of validated scales by varying approaches (face-to-face, low-bandwidth, and high-bandwidth videoconferencing) in a randomized order. In a second study, undergraduate nursing students performed similar performance measures and taught an unfamiliar individual how to program and use an intravenous pump device, take a tympanic temperature, or to draw up insulin in a syringe. In the third study, advanced practice nursing students assessed vital signs and performed cardiopulmonary assessments on community-dwelling subjects using low-bandwidth and face-to-face approaches. Healthcare practitioners and students generally preferred high-bandwidth approaches over low-bandwidth alternatives when videoconferencing was performed; however, most participants and practitioners were satisfied with the encounters, regardless of the level of technology used.

A telehomecare model for optimizing rehabilitation outcomes.

For telehealth to become an accepted component of rehabilitation, a scientific base verifying that telehealth improves outcomes must be developed. A conceptual framework based on theory and empirical findings is necessary for this area of inquiry to flourish. Most academic curricula possess such an educational pillar, which serves to help prepare professionals to practice in the new arena, and scholars to perform quality research. Currently, the authors are involved in developing areas of the biomedical engineering and nursing curricula at Marquette University to address key areas of telerehabilitation. This paper outlines the conceptual framework for these curricular areas. The conceptual framework is derived from three areas that modulate each other, and ultimately impact the outcomes of telerehabilitation. These areas are rehabilitative biosystems, human-technology interfaces, and behavioral compliance. Each can be viewed from the context of an optimization process, and the model can be applied to help identify the weak link for a given telerehabilitative approach under study. Examples of how the model can be used to frame telerehabilitation research are presented, with a special focus on designing home-based solutions for two societal challenges of large scope and great need-stroke and cardiac rehabilitation. The authors conclude that the proposed framework can be used to conceptualize, understand, and optimize the key components of a telerehabilitative process and to analyze alternative approaches for optimizing outcomes.
