RESUMO

BACKGROUND: Coincident with the proliferation of employer-provided mobile communication devices, personal communication devices, including basic and enhanced mobile phones (smartphones) and tablet computers that are owned by the user, have become ubiquitous among registered nurses working in hospitals. While there are numerous benefits of personal communication device use by nurses at work, little is known about the impact of these devices on in-patient care. OBJECTIVE: Our aim was to examine how hospital-registered nurses use their personal communication devices while doing both work-related and non‒work-related activities and to assess the impact of these devices on in-patient care. METHODS: A previously validated survey was emailed to 14,797 members of two national nursing organizations. Participants were asked about personal communication device use and their opinions about the impact of these devices on their own and their colleagues' work. RESULTS: Of the 1268 respondents (8.57% response rate), only 5.65% (70/1237) never used their personal communication device at work (excluding lunch and breaks). Respondents self-reported using their personal communication devices at work for work-related activities including checking or sending text messages or emails to health care team members (29.02%, 363/1251), as a calculator (25.34%, 316/1247), and to access work-related medical information (20.13%, 251/1247). Fewer nurses reported using their devices for non‒work-related activities including checking or sending text messages or emails to friends and family (18.75%, 235/1253), shopping (5.14%, 64/1244), or playing games (2.73%, 34/1249). A minority of respondents believe that their personal device use at work had a positive effect on their work including reducing stress (29.88%, 369/1235), benefiting patient care (28.74%, 357/1242), improving coordination of patient care among the health care team (25.34%, 315/1243), or increasing unit teamwork (17.70%, 220/1243). A majority (69.06%, 848/1228) of respondents believe that on average personal communication devices have a more negative than positive impact on patient care and 39.07% (481/1231) reported that personal communication devices were always or often a distraction while working. Respondents acknowledged their own device use negatively affected their work performance (7.56%, 94/1243), or caused them to miss important clinical information (3.83%, 47/1225) or make a medical error (0.90%, 11/1218). Respondents reported witnessing another nurse's use of devices negatively affect their work performance (69.41%, 860/1239), or cause them to miss important clinical information (30.61%, 378/1235) or make a medical error (12.51%, 155/1239). Younger respondents reported greater device use while at work than older respondents and generally had more positive opinions about the impact of personal communication devices on their work. CONCLUSIONS: The majority of registered nurses believe that the use of personal communication devices on hospital units raises significant safety issues. The high rate of respondents who saw colleagues distracted by their devices compared to the rate who acknowledged their own distraction may be an indication that nurses are unaware of their own attention deficits while using their devices. There were clear generational differences in personal communication device use at work and opinions about the impact of these devices on patient care. Professional codes of conduct for personal communication device use by hospital nurses need to be developed that maximize the benefits of personal communication device use, while reducing the potential for distraction and adverse outcomes.

RESUMO

Faculty to teach and mentor doctoral nursing students are and will continue to be in short supply. Coupled with ever-increasing resource-constricted educational environments, doctoral programs are challenged to provide high-quality education with limited resources. The Nursing Education Exchange (NEXus) is a viable solution to help meet that challenge. This article presents an overview of the origins and evolution of NEXus, financial considerations, and basic steps for joining NEXus, along with 4 exemplars. NEXus has continued to grow since its inception in 2007. In 2015, the number of NEXus schools reached 20, with 11 schools offering both doctor of philosophy and doctor of nursing practice courses. Currently, NEXus offers over 160 courses, organized into 14 clusters such as gerontology and chronic illness. Recently, a collaboration between the National Hartford Centers of Gerontological Nursing Excellence and NEXus was formalized. This collaboration prepares faculty to address an aging population. In summary, in an era of increased demand for doctoral prepared nurses, a lack of qualified doctoral nursing faculty, and limited financial resources, the NEXus collaborative provides a model for optimal resource sharing.

RESUMO

Nursing is the largest segment of the healthcare workforce, but over the next decade even more nurses will be required. Changing population demographics, new technologies, and evolving models of healthcare will stimulate expansion of nursing roles and the need for a highly educated nursing workforce. The current nursing workforce is aging, and large numbers of retirements are anticipated. By 2025, the United States is expected to experience a nursing shortage; in Hawai'i this shortfall is forecast to be 3,311 professional nurses. Currently there are nine nursing programs across the state in public and private universities and colleges. These programs are partnering to implement the Institute of Medicine's recommendations for the future of nursing. In Hawai'i, nursing practice is being expanded; different pathways to advanced nursing education are being implemented; and nurses are partnering with other groups to reshape healthcare. The Hawai'i State Center for Nursing collects ongoing data on the nursing workforce to inform strategic planning. Current gaps in nursing specialty education include school health and mental health. The purpose of this paper is to provide an overview of Hawai'i's nursing workforce in relationship to statewide population demographics, healthcare needs and gaps, and then outline steps being taken by the profession to address these needs and gaps while implementing the Institute of Medicine recommendations.

RESUMO

BACKGROUND: Personal mobile phones and other personal communication devices (smartphones and tablet computers) provide users with an ever-increasing number and diversity of non-work-related activities while at work. In hospitals, where the vigilance of health care workers is essential for patient care, the potential distraction of these devices could be hazardous to patients. OBJECTIVE: The objective of this study was to determine the frequency of non-work-related use of personal mobile phones and other personal communication devices among hospital registered nurses. METHODS: In March 2014, a previously validated 30-question survey was emailed to the 10,978 members of the Academy of Medical Surgical Nurses. There were 825 respondents who met the inclusion criteria. RESULTS: The use of a personal mobile phone or other personal communication device while working (excluding meal times and breaks) was reported by 78.1% (644/825) of respondents. Nurses reported regularly (sometimes, often, or always) sending personal emails and text messages (38.6%, 318/825), reading news (25.7%, 212/825), checking/posting on social networking sites (20.8%, 172/825), shopping (9.6%, 79/825), and playing games (6.5%, 54/825) while working. CONCLUSIONS: This study found that hospital nurses frequently use their personal mobile phones or other personal communication devices for non-work-related activities at work. The primary activity reported was to send personal emails and text messages to family and friends.

RESUMO

BACKGROUND: Prior research has documented the effect of concurrent mobile phone use on medical care. This study examined the extent of hospital registered nurses' awareness of their mobile-phone-associated performance decrements. OBJECTIVE: The objective of this study was to compare self-reported performance with reported observed performance of others with respect to mobile phone use by hospital registered nurses. METHODS: In March 2014, a previously validated survey was emailed to the 10,978 members of the Academy of Medical Surgical Nurses. The responses were analyzed using a two-proportion z test (alpha=.05, two-tailed) to examine whether self-reported and observed rates of error were significantly different. All possible demographic and employment confounders which could potentially contribute to self-reported and observed performance errors were tested for significance. RESULTS: Of the 950 respondents, 825 (8.68%, 825/950) met the inclusion criteria for analysis. The representativeness of the sample relative to the US nursing workforce was assessed using a two-proportion z test. This indicated that sex and location of primary place of employment (urban/rural) were represented appropriately in the study sample. Respondents in the age groups <40 years old were underrepresented, while age groups >55 years old were overrepresented. Whites, American Indians/Alaskan natives, and Native Hawaiian or Pacific Islanders were underrepresented, while Hispanic and multiple/other ethnicities were overrepresented. It was decided to report the unweighted, rather than the weighted survey data, with the recognition that the results, while valuable, may not be generalizable to the entire US registered nursing workforce. A significant difference was found between registered nurses' self-reported and observed rates of errors associated with concurrent mobile phone use in following three categories (1) work performance (z=-26.6142, P<.001, Fisher's exact test), (2) missing important clinical information (z=-13.9882, P=.008, Fisher's exact test), and (3) making a medical error (z=-9.6798, P<.001, Fisher's exact test). Respondents reported that personal mobile phone use by nurses at work was a serious distraction; always (13%, 107/825), often (29.6%, 244/825), sometimes (44.6%, 368/825), rarely (8.7%, 72/825), or never (1.2%, 10/825). On balance, 69.5% (573/825) of respondents believed that nurses' use of personal mobile phones while working had a negative effect on patient care. Since all possible confounders were tested and none were deemed significant, a multivariate analysis was not considered necessary. CONCLUSIONS: Many hospitals are drawing up policies that allow workers to decide how to use their devices at work. This study found that nurses express a disproportionately high confidence in their ability to manage the risk associated with the use of mobile phones and may not be able to accurately assess when it is appropriate to use these devices at work.

RESUMO

BACKGROUND: The use of personal communication devices (such as basic cell phones, enhanced cell phones or smartphones, and tablet computers) in hospital units has risen dramatically in recent years. The use of these devices for personal and professional activities can be beneficial, but also has the potential to negatively affect patient care, as clinicians may become distracted by these devices. OBJECTIVE: No validated questionnaire examining the impact of the use of these devices on patient care exists; thus, we aim to develop and validate an online questionnaire for surveying the views of registered nurses with experience of working in hospitals regarding the impact of the use of personal communication devices on hospital units. METHODS: A 50-item, four-domain questionnaire on the views of registered nursing staff regarding the impact of personal communication devices on hospital units was developed based on a literature review and interviews with such nurses. A repeated measures pilot study was conducted to examine the psychometrics of a survey questionnaire and the feasibility of conducting a larger study. Psychometric testing of the questionnaire included examining internal consistency reliability and test-retest reliability in a sample of 50 registered nurses. RESULTS: The response rate for the repeated measures was 30%. Cronbach coefficient alpha was used to examine the internal consistency and reliability, and in three of the four question groups (utilization, impact, and opinions), the correlation was observed to be very high. This suggests that the questions were measuring a single underlying theme. The Cronbach alpha value for the questions in the performance group, describing the use of personal communication devices while working, was lower than those for the other question groups. These values may be an indication that the assumptions underlying the Cronbach alpha calculation may have been violated for this group of questions. A Spearman rho correlation was used to determine the test-retest reliability. There was a strong test-retest reliability between the two tests for the majority of the questions. The average test-retest percent of agreement for the Likert scale responses was 74% (range 43-100%). Accounting for responses within the 1 SD range on the Likert scale increased the agreement to 96% (range 87-100%). Missing data were in the range of 0 to 7%. CONCLUSIONS: The psychometrics of the questionnaire showed good to fair levels of internal consistency and test-retest reliability. The pilot study demonstrated that our questionnaire may be useful in exploring registered nurses' perceptions of the impact of personal electronic devices on hospital units in a larger study.

RESUMO

With the passage of the Affordable Care Act and the development of a National Workforce Commission, multiple entities have increased their interest in collecting standardized health care workforce data at the state and national levels. In a tight budget environment, developing data sets which collect the minimum needed information that is necessary for workforce planning and supply/demand projections has become critically needed. This article represents the second of a two part series describing the work that the Forum of State Nursing Workforce Centers has undertaken during the last 3 years toward standardizing nursing workforce data. Part I described the initial steps that informed the development of national nursing workforce minimum data sets. Part II describes the consensus model used to develop the minimum data sets as well as an update on the implementation of the minimum data sets in individual states including challenges and barriers encountered.

RESUMO

The chronic nature of the nursing workforce shortage in the United States is a continuing concern. As the nationwide gap between supply and demand grows, it remains unknown what impact turnover will have on nursing, access to care, and efforts to improve quality and safety of health care. It also remains unclear whether the recent turnover trends among new graduate registered nurses differ from past generational cohorts of new nurses. The aims of this study were to identify the reasons why registered nurses turnover by generational cohort (Veterans, Baby Boomers, and GenXMs) and to compare the length of time nurses were employed in their first five nursing positions by generational cohort. The findings suggest the three generational cohorts displayed similar reasons for leaving nursing positions with relocation, career advancement, and personal/family reasons reported most frequently. Except for the first nursing position, significant generational effects were found in the length of time Veterans, Baby Boomer, and GenXMs stayed employed in their nursing positions. It remains unknown why the GenXMs displayed a significantly shorter length of employment time in their second, third, fourth, and fifth nursing positions. The decline in length of employment time displayed in both the Baby Boomers and GenXMs may be an issue of concern requiring future research.

RESUMO

OBJECTIVES: This paper examines the applicability and construct validity of the Schedule for the Evaluation of Individual Quality of Life-Direct Weight (SEIQoL-DW) for measuring quality of life in stroke survivors living at home that attend a secondary prevention clinic. PARTICIPANTS AND METHODS: Forty-six individuals attending a secondary prevention clinic following a stroke or transient ischaemic attack participated in a semi-structured interview to complete a range of outcome measures. Assessments of cognitive impairment, disability, and handicap were conducted using the Mini mental State Examination (MMSE), Barthel Index (BI), and Rankin Scale (RS). Measures to assess quality of life included perceived health status (PHS), Visual Analogue Mood Scale (VAMS), the Hospital Anxiety and Depression Scale (HADS), and the SEIQoL-DW. The construct validity of the SEIQoL-DW was assessed by correlation with the other measures. RESULTS: According to the cues elicited from the SEIQoL-DW, participants nominated 'relationships with family and friends' as the most important life domain, followed by 'social and leisure activities', and 'health'. Spearman's rho correlation coefficients demonstrated significant relationships between the SEIQoL-DW index scores, PHS (r = 0.35, p = 0.016), VAMS (r = 0.419, p = 0.004), and the HADS anxiety (r = -0.546, p < 0.0001) and depression (r = -0.701, p < 0.0001) subscale scores. CONCLUSIONS: The SEIQoL-DW demonstrated reasonable construct validity for use in assessing individual quality of life in a group of individuals following stroke or TIA that attend a secondary prevention clinic.

RESUMO

STUDY OBJECTIVE: The purpose of this study is to examine emergency nurses' performance using triage scenarios characterized by type of patient population (adult versus pediatric) and mode of delivery (paper versus computer). METHODS: A combination of paper-based (script alone) and computer-based (script plus still photographs) triage scenarios were used. Of the 28 scenarios used, half were written and half were computer based. Within each subgroup, there were 7 adult and 7 pediatric scenarios. Participants were asked to allocate an Australasian Triage Scale category for each triage scenario. RESULTS: One hundred sixty-seven participants completed a total of 2,349 adult scenarios, and 161 participants completed 2,265 pediatric scenarios. Sixty-one percent of the triage decisions made by the nurses were "expected" triage decisions, 18% were "undertriage," decisions, and 21% were "overtriage" decisions. Nurse triage allocation decisions for the scenarios containing still photographs delivered by computer demonstrated a higher average agreement percentage of 66.2% (kappa=0.56; tau b =0.77; P <.0001) compared with the average agreement percentage of 55.4% (kappa=0.42; tau b =0.75; P <.0001) using paper-based (text-only) scenarios. CONCLUSION: The mode of delivery appeared to have an effect on the nurses' triage performance. It is unclear whether the use of simple still photographs used in the computer mode of delivery resulted in a higher incidence of expected triage decisions and, thus, improved performance. The use of cues such as photographs and video footage to enhance the fidelity of triage scenarios may be useful not only for the education of triage nurses but also the conduct of research into triage decisionmaking. However, further exploration and research in this area are warranted.

RESUMO

BACKGROUND: Families who accompany critically ill relatives in emergency departments (EDs) are an integral part of the care unit. However, there are few empirical data on their needs during this phase of care. In order to guide quality care, general and specific needs of families accompanying these critically ill relatives should be systematically examined. AIM: The aim of this pilot project was to test the tool, methods and analysis plan for a study to examine the perceived needs of family members accompanying critically ill patients in EDs and their perceptions of ED staff's ability to meet these needs. METHOD: Over a 6-week period in 1996, 84 relatives who met the inclusion criteria were recruited to the study. A postal questionnaire, to uncover the needs of family members, was pilot tested. The questionnaire consisted of 40 need statements reflecting five major themes: meaning, proximity, communication, comfort and support. Of the 84 relatives selected for the study, 73% returned completed questionnaires. RESULTS: The findings of this pilot study suggest that the questionnaire is a valid and reliable tool for researchers wishing to examine and rank the needs of family members who accompany critically ill people in EDs. In addition, the analysis plan was found to be appropriate. CONCLUSIONS: This pilot study provides both a method and a tool for further research into family needs. Examination of the pilot data supported the reliability and validity of the tool and produced findings that challenge nurses to move beyond traditional practice that has excluded families from being an integral part of caring for critically ill patients in EDs.

RESUMO

The Consistency of Triage in Victoria's Emergency Departments Project (2001), funded by the Victorian Department of Human Services, aimed to improve the consistency of application of the Australasian (National) Triage Scale (ATS). One of the major objectives of the project was the development of an education strategy to promote a consistent approach to triage education, leading to the development of the Adult Physiological Discriminators (APDs) for the ATS and Paediatric Physiological Discriminators (PPDs) for the ATS. The guidelines and physiological discriminators were developed in consultation with the Emergency Nurses' Association of Victoria (ENA Vic.) and clinical nurse educators, lecturers, nurse unit managers and clinicians from a wide variety of Emergency Departments (EDs) across Victoria. Numerous studies have identified varying degrees of inconsistency in the application of the ATS. A number of factors associated with inconsistency in the application of the ATS have also been alluded to in the literature. These range from the wide variation in the experiential and educational requirements of Victorian triage nurses to the specific clinical characteristics of the patient identified by the triage nurse. However, a consistent approach to triage education and uniform triage guidelines has been repeatedly identified as a key factor in improving the consistency of application of the ATS. Physiological data demonstrates the highest degree of objectivity and consistency and research has shown that physiological observations are useful and measurable indicators of clinical urgency and patient safety. This paper will discuss the development of these discriminators as part of the educational strategy including a critique of other approaches to triage decision-making and a review of the consultative processes used to facilitate consensus amongst triage nurses, ED Nurse Managers and ED Nurse Educators. The physiological discriminators developed by this project are also presented.

RESUMO

The present study was undertaken to examine possible changes in subjective appraisal and central nervous system processing, indexed by pain-related cerebral evoked potentials (N290, P400), of incoming noxious information in 20 pain-free control volunteers and 18 subjects suffering from right-side cervico-brachial pain (CBS). Detection threshold and cerebral evoked potentials were recorded in response to noxious CO2 laser stimulation of the right and left hands. The results indicate that when compared to controls, CBS subjects exhibit an elevation in detection threshold intensity and a reduction in the amplitude of the P400 peak following laser stimulation of the pain affected side. There were also differences in the choice of qualitative descriptor for laser stimuli although not in the subjective rating of stimulus intensity. These changes were not apparent for responses on the unaffected limb. The severity of clinical pain was found to be related to the magnitude of reduction in P400 amplitude only on the pain affected side. Conversely, feelings of anxiety were associated with higher amplitude responses on both the right and left sides, suggesting a more generalized relationship between these factors. We interpret these findings to indicate an alteration in central nervous system processing and subjective appraisal of acute experimental pain in subjects with chronic CBS. Moreover, these alterations appear to be restricted to pain affected pathways and are more related to the severity of clinical pain than to general mood state.

RESUMO

The present study was undertaken to investigate the possible involvement of peripheral nociceptors in 3 diagnostic categories of elderly patients with chronic pain. The 3 diagnostic groups consisted of: chronic lower lumbar pain of degenerative musculoskeletal etiology (LLP), post-herpetic neuralgia (PHN) and pain of non-organic origin in a group with a predominantly psychiatric disorder (PPD). The last group had pain confined to the trunk. All patients documented subjective pain using a visual analogue scale and an 8-item pain descriptor scale. Topical application of capsaicin was used to induce an axon reflex flare in 25 patients with pain and 29 control subjects. Three forms of measurement were used: flare size measured by tracing and by laser Doppler flowmetry, latency to onset of increased skin blood flow and blood flux. The groups with LLP and PHN had reduced flares at the affected site by all 3 measures, whereas no decrease was observed in the PPD group. No significant difference was found between groups when tested on a control site remote from the affected area using the 3 forms of measurement. We suggest that an alteration in the function of capsaicin-sensitive sensory fibers could be related to the subjective report of subacute and chronic pain in diagnostic groups such as LLP and PHN where there is a known organic cause.
