Retention in nursing education and scholarship programs: Survival analysis of the Veterans Health Administration National Nursing Education Initiative Data.

AIMS: To investigate factors affecting non-completion by registered nurses (RNs) participating in degree programs supported by the scholarship program of the National Nursing Education Initiative of the United States Veterans Health Administration. Secondarily, to assess overall retention in the scholarship program over time. DESIGN: Retrospective longitudinal design using administrative data. METHODS: Defining retention time as the time elapsed from enrollment date to non-completion, we performed survival (retention) analysis (i.e.,Kaplan-Meier survival functions, log-rank tests and Cox regressions) to retrospectively analyzea national sample of RNs (N  = 15,908) enrolled in the scholarship program between the United States federal fiscal years 2000 and 2020. RESULTS: Nurses' mean age was 44 years (range: 19-71), and 86% were females. Six- and 12-month cumulative educational program retention rates were 92% and 84% respectively. The newest group of enrollees (2016-2020), younger nurses (<50 years), and nurses in traditional degree programtype were more likely to complete their academic programs than the earlier groups, older nurses and nurses in non-traditional type, respectively. Male nurses who aspired to advanced occupational levels upon completion were more likely to complete their academic programs compared to those who expected no change from their current level of practice. CONCLUSION: Multiple factors affected non-completion of academic degree programs by RNs enrolled in the scholarship program. More work is needed to examine these plus additional plausible factors and their correlates extensively. IMPACT: Our findings highlighted areas for quality improvement in employee scholarship programs for RNs. The findings are expected to inform tailoring of proactive helpful intervention towards individual needs and prioritization of limited resources to maximize graduation rate from academic programs for scholarship recipients. The study will have impact on nursing workforce policy makers interested in implementing employee scholarship programs, and on their scholarship recipients.

Reliability and validity of the Veterans Administration Mobility Screening and Solutions Tool.

OBJECTIVES: The Veterans Administration (VA) Mobility Screening and Solutions Tool (VA MSST) was developed to screen a patient's safe mobility level 'in the moment' and provide clinical decision support related to the use of safe patient handling and mobility (SPHM) equipment. This evidence-based flowchart tool is a common language tool that enables any healthcare worker at any time to accurately measure and communicate patient mobility and transfer equipment needs across disciplines and settings. METHODS: The VA MSST has four levels and differentiates between the need for powered and non-powered equipment depending on the patient's independence. Subject matter experts wrote scenarios for interrater reliability and validity testing. The initial VA MSST draft iteration was reviewed by 163 VA staff (mostly physical therapists and occupational therapists) amongst simulation scenarios and provided content validity, and additional insight and suggestions. Revisions were made to create the final VA MSST which was evaluated by over 200 healthcare workers from varied disciplines (including medical doctors, advanced practice registered nurses, registered nurses, licensed practical nurses, certified nursing assistants, occupational therapists, physical therapists, speech therapists, radiology and ultrasound technicians, etc.). An instruction video and eighteen scenario videos were embedded in an online survey. The survey intended to demonstrate the interrater reliability and validity (concurrent and construct) of the VA MSST. Over 500 VA staff (raters) received a survey invitation via email. RESULTS: Raters (N = 230) from multiple disciplines and healthcare settings independently screened patient mobility status for each of 18 scenarios using the VA MSST. The raters were diverse in their age and years of experience. The estimated interrater reliability (IRR) for VA MSST was excellent and statistically significant with an estimated Krippendorff's alpha (ICC (C, k)) of 0.998 [95% CI: 0.996-0.999]. Eighty-two percent of raters reported that overall VA MSST instructions were clear or very clear and understandable. VA MSST ratings made by technicians and nursing assistants group correlated strongly (r = 0.99, p < 0.001) with the 'gold standard' (experienced physical therapists), suggesting a high concurrent validity of the tool. The VA MSST significantly discriminated between the different levels of patient mobility required for safe mobilization as intended (each difference, p < 0.0001); this suggests a good construct validity. CONCLUSIONS: The VA MSST is an evidence-based flowchart screening and decision support tool that demonstrates excellent interrater reliability across disciplines and settings. VA MSST has strong face and content validity, as well as good concurrent and construct validity.

A preliminary evaluation of full practice authority of advance practice registered nurses in the Veterans Health Administration.

BACKGROUND: Responding to National Academy of Medicine and National Council of State Boards of Nursing recommendations, the Department of Veterans Health Affairs (VHA) implemented full practice authority (FPA) for Advanced Practice Registered Nurses in VHA medical centers (VAMCs) in 2017. PURPOSE: To evaluate FPA policy implementation's impact on quality indicators including access to care as measured by new patient appointments in primary, specialty and mental health services. METHODS: Linear growth models compared early (n = 85) vs. late (n = 55) FPA implementing VAMCs on the trajectories of each of the three quality indicators. FINDINGS: Early FPA implementing VAMCs showed greater rates of improvement over time in new patient appointments completed within 30 days of preferred date for primary care (p = .003), specialty care (p = 0.05), and mental health (p = 0.001). DISCUSSION: VAMCs that started implementation of FPA policy early showed greater improvement in access to care for Veterans over time than VAMCs that did not.

Mortality and Associated Risk Factors in Community-Dwelling Persons With Early Dementia.

OBJECTIVE: Examine mortality and associations with baseline characteristics among Veterans with early dementia. METHODS: Participants included dyads of community-based Veterans with early dementia and their caregivers (N=143) enrolled in a previous longitudinal study. Department of Veterans Health Affairs' electronic records were used to retrospectively collect Veteran mortality outcomes, over a 6-year period. Measures included baseline: demographics, dementia-related factors, other comorbid conditions, functioning, and medication use. Associations with baseline characteristics and mortality were examined with bivariate analyses and a series of Cox proportional hazard models. RESULTS: Over 6 years of study follow-up, 53.1% of participants died. The mean time to death was 3.09 years, with a range of 54 days to 5.91 years. Female sex, better cognition, and higher scores on the Tinetti Gait and Balance scale were protective factors in the final multivariable model, adjusting for other characteristics. CONCLUSIONS: While newly diagnosed with early dementia, over half of our sample died in the 6-year follow-up period, with the average death occurring only 3 years after initial diagnosis. The finding of lower mortality associated with better performance on gait/balance testing indicates an important opportunity for focused interventions and early detection of gait and balance changes early during cognitive decline.

Pressure ulcer summit 2018: An interdisciplinary approach to improve our understanding of the risk of pressure-induced tissue damage.

Pressure ulcers (PrUs) affect approximately 2.5 million patients and account for 60,000 deaths annually. They are associated with an additional annual cost of $43,000 per related hospital stay and a total cost to the US health care system as high as $25 billion. Despite the implementation of national and international PrU prevention guidelines and toolkits, rates of facility-acquired PrU s and PrUs in people with spinal cord injury are still high. A new paradigm is needed that distinguishes between prevention and treatment research methods and includes not only the causative factors of pressure and tissue deformation but also patient-specific anatomical differences and the concomitant biological cellular processes, including reperfusion injury, toxic metabolites, ischemia, cell distortion, impaired lymphatic drainage, and impaired interstitial fluid flow that compound existing tissue damage. The purpose of this article is to summarize the highlights from the first annual Pressure Ulcer Summit held February 9-10, 2018 in Atlanta, Georgia (sponsored by the Association for the Advancement of Wound Care in partnership with multiple professional organizations). This international, interdisciplinary summit brought together key stakeholders in wound care and PrU prevention and management to highlight advances in pathophysiology of pressure-induced tissue damage; explore challenges in current terminologies, documentation, and data collection; describe innovations in clinical care; and identify research opportunities to advance the science of PrU prevention and management.

Pressure Ulcer Prevalence by Level of Paralysis in Patients With Spinal Cord Injury in Long-term Care.

OBJECTIVE: Scientific literature suggests pressure ulcer (PU) risk increases as immobility increases, indicating that more extensive paralysis confers a greater risk of PU. Yet the specific level of paralysis (ie, hemiplegia vs paraplegia vs quadriplegia), apart from neurodegenerative diagnoses, has never been examined in the long-term care (LTC) population. This study examined the prevalence of PU among LTC residents with different paralysis levels. METHODS: The authors conducted a secondary data analysis of the 2012 US Minimum Data Set of LTC facilities (n = 51,664 residents). Measures included PU stage, level of paralysis, functional impairments, comorbidities, and sociodemographic factors. After removing residents with neurodegenerative disease, comatose patients, and those with hip fractures from the analysis, logistic regressions were used to examine the association of risk factors and sociodemographic characteristics with the presence of PU. MAIN RESULTS: The sample included 7,540 patients with quadriplegia, 11,614 patients with paraplegia, and 32,510 patients with hemiplegia in LTC facilities. The PU prevalence in the sample (stages 2, 3, and 4; suspected deep-tissue injury; and unstageable PUs) was 33.9% for patients with quadriplegia, 47.4% for patients with paraplegia, and 9.6% for patients with hemiplegia. CONCLUSIONS: Within paralysis groups (quadriplegic, paraplegic, hemiplegic), risk factors for PU differed in type and magnitude. The PU rates associated with quadriplegia and paraplegia are much higher than LTC residents without paralysis, and PU prevalence for hemiplegia is similar to the rate in LTC residents without paralysis. When the risk factor of paraplegia versus quadriplegia was isolated, PU prevalence for patients with paraplegia was significantly higher.

Research productivity following nursing research initiative grants.

BACKGROUND: In 1995, VA's Office of Research and Development launched the Nursing Research Initiative (NRI), to encourage nurses to apply for research funding and to increase the role of nurse investigators in the VA's research mission. This program provides novice nurse researchers the opportunity to further develop their research skills with the guidance of a mentor. PURPOSE: Since the NRI's inception, its impact on the research career trajectory of budding nurse researchers had never been fully explored. METHODS: An electronic quality improvement survey was developed to collect information about the scope of work and research trajectory of VA nurse researchers undertaken since they received NRI funding. FINDINGS: NRI awardees demonstrated research productivity in several areas including research funding, peer-reviewed publications; participation on journal editorial boards and grant review committees; and mentorship. The majority of past NRI grant recipients (78%) have maintained employment within the VA system and benefit from the expertise, mentoring, and support of other nurse researchers. NRI grant recipients confirm the value of the VA NRI mentored grant funding mechanism and its association with a productive research trajectory with survey respondents demonstrating an average return on investment of $7.7 million in research funding per person. CONCLUSION: The experiences derived from the NRI accelerated the professional growth and research productivity of this group and it guided future opportunities to design, implement, and test nurse-led interventions.

Pressure Injury Documentation Practices in the Department of Veteran Affairs: A Quality Improvement Project.

Evidence suggests that inaccurate and incomplete pressure injury (PI) documentation threatens the validity of treatment and undermines policy and quality improvement. This quality improvement project sought to identify barriers and facilitators when conducting and documenting the daily comprehensive skin assessment in 31 Department of Veterans Affairs (VA) facilities. Evaluators in this 1-year, cross-sectional quality improvement project, using a qualitative approach, interviewed nurses of medical-surgical and critical care units. Participants (N = 62) from 12 high reassessment units (HRUs) and 13 low reassessment units (LRUs) were interviewed using telephone focus groups. Staff from HRUs reported 9 activities that ensured consistency in clinical practices, in validating data, and in correcting inaccuracies. The LRU staff tended to report performing only 2 of the 9 activities. The main barriers to accurate documentation were lack of knowledge, poor templates, and staffing issues such as understaffing and turnover, and main facilitators were an internal data validation process and a documentation template to local practices. Findings from this project led to increased VA leadership engagement, development of 3 innovative, award-winning VA mobile PI prevention and management applications, updated policies and directives on PI prevention, and upgrading of the national VA HAPI workgroup to an advisory committee and improved collaboration between the PI advisory committee and nursing informatics.

Pressure Injury Education in the Department of Veterans Affairs: Results of a National Wound Provider Cross-sectional Survey.

PURPOSE: The aim of this study was to describe experience, training, educational needs and preferences, and perceptions of pressure injury (PI) prevention education of wound care providers in the Veterans Health Administration (VHA) of the Department of Veterans Affairs (VA) as an indicator of effectiveness of the mandated VHA PI Prevention Program. SUBJECTS AND SETTING: A convenience sample of national VHA wound care providers practicing in VHA facilities was compiled from members of special interest groups and committees and by referrals from known wound care specialists and clinicians (N = 1726). The response rate was 24% (n = 410). DESIGN: Cross-sectional, descriptive study. METHODS: A 42-item online cross-sectional survey was administered via a blast-email of the survey link to the sample. The survey link was active for 1 month (March 3-31, 2014). The survey queried demographic data, PI experience and education, and their perceptions and preferences for PI education. Quantitative responses underwent descriptive analyses, and responses to open-ended questions were analyzed by content analysis. RESULTS: The majority of the 415 respondents completed most of the questionnaire (n = 310, 74%). Half were board-certified providers with a mean wound care experience of 14.2 years (standard deviation = 9.8 years). Preference for type of wound training ranged from 17% for online gaming to 82% for face-to-face training. Training provided by facilities was perceived to be inadequate for wound care by 60% (n = 175) and inadequate for PI care by 49% (n = 142). CONCLUSIONS: The 2 greatest areas of need in PI care identified by wound care providers were education and documentation. These same issues were identified as problematic by an audit of PI prevention and management at 47 VHA facilities that was conducted by the VA Office of Inspector General.

Upfront lower dose lenalidomide is less toxic and does not compromise efficacy for vulnerable patients with relapsed refractory multiple myeloma: final analysis of the phase II RevLite study.

The combination of lenalidomide and dexamethasone is an established treatment for patients with multiple myeloma (MM). Increasingly, treatment attenuation is advocated for frail/elderly patients to minimize toxicity even though there have been no prospective studies to demonstrate whether lenalidomide dose attenuation impacts on response and survival outcome. This prospective multicentre phase II study assessed the efficacy and tolerability of lower dose lenalidomide (15 mg) and dexamethasone (20 mg) in 149 eligible patients with relapsed/refractory MM aged over 59 years and/or with renal impairment. The overall response rate was 71% (complete response 15%). Median (range) progression-free survival (PFS) and overall survival (OS) were 8·9 (6·9-11·5) and 30·5 (20·0-36·2) months, respectively. Upon formal statistical comparison of these endpoints to that of a matched cohort of patients from the pivotal phase III MM009/MM010 studies who received standard-dose lenalidomide (25 mg) and high-dose dexamethasone (40 mg) no difference was seen in PFS (P = 0·34) and OS (P = 0·21). Importantly, grade 3-4 toxicities were reduced with low-dose lenalidomide, mainly lower neutropenia (29% vs. 41%), infections (23% vs. 31%) and venous thromboembolism (3% vs. 13%). This study supports a strategy of lenalidomide dose reduction at the outset for at-risk patients, and prospectively confirms that such an approach reduces adverse events while not compromising patient response or survival outcomes.

Risk Factors for Pressure Ulcers Including Suspected Deep Tissue Injury in Nursing Home Facility Residents: Analysis of National Minimum Data Set 3.0.

PURPOSE: To provide information on risk factors associated with pressure ulcers (PrUs), including suspected deep tissue injury (sDTI), in nursing home residents in the United States. TARGET AUDIENCE: This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. OBJECTIVES: After participating in this educational activity, the participant should be better able to:1. Examine the literature related to risk factors for the development of PrUs.2. Compare risk factors associated with the prevalence of PrUs and sDTI from the revised Minimum Data Set 3.0 2012 using a modified Defloor's conceptual model of PrUs as a theoretical framework. OBJECTIVE: This study aims to characterize and compare risk factors associated with pressure ulcers (PrUs), including suspected deep tissue injury (sDTI), in nursing home (NH) residents in the United States. DESIGN: Secondary analysis of the 2012 Minimum Data Set (MDS 3.0). SETTING: Medicare- or Medicaid-certified NHs in the United States. PARTICIPANTS: Nursing home residents (n = 2,936,146) 18 years or older with complete PrU data, who received comprehensive assessments from January to December 2012. MEASUREMENTS: Pressure ulcer by stage was the outcome variable. Explanatory variables (age, gender, race and ethnicity, body mass index, skin integrity, system failure, disease, infection, mobility, and cognition) from the MDS 3.0 were aligned with the 4 elements of Defloor's conceptual model: compressive forces, shearing forces, tissue tolerance for pressure, and tissue tolerance for oxygen. RESULTS: Of 2,936,146 NH residents who had complete data for PrU, 89.9% had no PrU; 8.4% had a Stage 2, 3, or 4 or unstagable PrU; and 1.7% had an sDTI. The MDS variables corresponding to the 4 elements of Defloor's model were significantly predictive of both PrU and sDTI. Black residents had the highest risk of any-stage PrU, and Hispanic residents had the highest risk of sDTI. Skin integrity, system failure, infection, and disease risk factors had larger effect sizes for sDTI than for other PrU stages. CONCLUSIONS: The MDS data support Defloor's model and inform clinicians, educators, researchers, and policymakers on risk factors associated with PrUs and sDTI in NH residents in the United States participating in Medicare and Medicaid.

Wound samples: moving towards a standardised method of collection and analysis.

Chronic wounds, including diabetic foot ulcers, pressure ulcers and venous leg ulcers, impact the lives of millions of people worldwide. These types of wounds represent a significant physical, social and financial burden to both patients and health care systems. Wound care has made great progress in recent years as a result of the critical research performed in academic, clinical and industrial settings. However, there has been relatively little translation of basic research discoveries into novel and effective treatments. One underlying reason for this paucity may be inconsistency in the methods of wound analysis and sample collection, resulting in the inability of researchers to accurately characterise the healing process and compare results from different studies. This review examines the various types of analytical methods being used in wound research today with emphasis on sampling techniques, processing and storage, and the findings call forth the wound care research community to standardise its approach to wound analysis in order to yield more robust and comparable data sets.

Is bisphenol-A exposure during pregnancy associated with blood glucose levels or diagnosis of gestational diabetes?

Recent epidemiological studies indicate bisphenol A (BPA), an estrogenic chemical used in production of epoxy, polycarbonate, and plastic may increase risk of insulin resistance and type 2 diabetes. Exposure to BPA during pregnancy may contribute to development of gestational diabetes mellitus (GDM), a precursor to type 2 diabetes in women. This pilot study examined the association between BPA exposure, fasting blood glucose levels (FBG), and GDM diagnosis during pregnancy. Banked urine samples from 22 cases of GDM and 72 controls were analyzed for total (free BPA + conjugates) urinary BPA concentrations (µg/L). FBG levels (mg/dl) were obtained from 1-h 50-g glucose tolerance tests (GTT) that women underwent for routine GDM screening (mean gestational age = 26.6 weeks, SD = 3.8). Those with an initial screening value ≥ 135 mg/dl underwent 3-h 100 g oral GTT. GDM diagnoses were made when the initial screening value was ≥ 200 mg/dl or when values at ≥ 2 time points exceeded 3-h oral GTT thresholds. Among controls, median FBG levels (mg/dL) did not differ across exposure tertiles, defined according to the distribution of total specific-gravity-adjusted urinary BPA concentrations. Logistic regression models controlling for race/ethnicity did not provide evidence of association between BPA exposure and case status across increasing tertiles of BPA exposure (number of GDM cases/controls in tertile1: 13/24; in tertile 2: 6/24; in tertile 3: 3/24). Findings do not support a relationship between total urinary BPA concentrations and altered glucose metabolism during pregnancy. However, due to study limitations, findings need to be interpreted with caution.

Staff Low Back Injury Risk During Assisted Falls Virtual Reality Simulations.

BACKGROUND: Assisted falls occur when staff try to minimize the impact of falls by slowing a patient's descent. Assisting a patient fall may decrease patient injury risk, but biomechanical risk of injury to staff has not been evaluated. Assisted falls virtual reality (VR) simulations were conducted to examine staff low back injury risk during common assisted falls scenarios. METHODS: VR simulations of a toilet to wheelchair transfer were developed with a male patient avatar for three assisted falls scenarios: standing up from toilet, sitting down on wheelchair, and ambulation. Patient avatar weight was modified to reflect normal, underweight, and overweight adult patients. The average spinal compression force at L5/S1 was calculated for each participant with five trials per three scenarios while utilizing physical ergonomic techniques and compared to the safe spinal compression limit of 3,400 Newtons (N). FINDINGS: Six staff participants completed 90 VR simulations in total. The average calculated spinal compression force ranged from 7,132 N to 27,901 N. All participant trials exceeded the safe spinal compression limit of 3,400 N for every assisted falls scenario and avatar weight despite application of ergonomic techniques including wide stance, knees bent, and backs straight. CONCLUSIONS/APPLICATION TO PRACTICE: Staff are at risk for low back injury if they assist falls regardless of the adult patient weight and application of ergonomic techniques. Safer alternatives like the implementation of mobility screening tools and safe patient handling and mobility technology are needed to help prevent assisted falls to decrease injury risk to both patients and staff.

Original Research: What Health Care Staff Who Experienced Assisted Patient Falls Can Teach Us: Implications for Fall and Fall Injury Risk.

PURPOSE: This quality improvement project had three aims: to identify common assisted falls scenarios, describe staff members' experiences with and risk perceptions of such falls, and explore factors that influenced their perceptions. The overarching goal was to gain useful insight for the development of assisted fall-related strategies and policies. METHODS: In the fall of 2020, 16 staff members from 13 health care facilities were purposively recruited and interviewed. Transcript summaries of these interviews, along with secondary narrative data from employee and patient injury databases, were analyzed using thematic content analysis. RESULTS: According to staff members' accounts, assisted falls most commonly took place in patient rooms or bathrooms when patients were ambulating or transferring. The interviewees described assisting falls by grabbing or holding the patient or by using their own body to brace or steady the patient. Interview and secondary narrative data noted various injuries that occurred during assisted fall events. These injuries most often involved the lower back (among staff) and the legs (among patients). Most interviewees perceived that using proper body mechanics would prevent injury. CONCLUSIONS: Interviewees' experiences with assisted falls indicate areas of improvement for fall prevention. The perception that using proper body mechanics will protect staff from injury may be a misconception. Although the literature reports mixed findings concerning whether staff should assist patient falls, this project's results led us to conclude that there is no safe way to physically assist a falling patient without risk of staff injury.

Prevalence of neurocysticercosis among people with epilepsy in rural areas of Burkina Faso.

PURPOSE: To estimate the lifetime prevalence of neurocysticercosis (NCC)-associated epilepsy and the proportion of NCC among people with epilepsy in three Burkina Faso villages. METHODS: Three villages were selected to represent three types of pig-rearing methods: (1) Batondo, where pigs are left to roam; (2) Pabré, where pigs are mostly tethered or penned; and (3) Nyonyogo, where the majority of residents are Muslim and few pigs are raised. In Batondo and Nyonyogo, all concessions (a group of several households) were included. Half of the concessions in Pabré were randomly chosen. All households of selected concessions were included, and one person per household was randomly selected for epilepsy screening and serologic testing for cysticercosis. Self-reported cases of epilepsy were also examined and confirmed cases included in analyses other than the estimate of NCC-associated epilepsy prevalence. Epilepsy was defined as ever having had more than one episode of unprovoked seizures. Individuals with medically confirmed epilepsy had a computerized tomography (CT) scan of the brain before and after contrast medium injection. The diagnosis of NCC was made using a modification of the criteria of Del Brutto et al. KEY FINDINGS: Thirty-nine (4%) of 888 randomly selected villagers and 33 (94%) of 35 self-reported seizures cases were confirmed to have epilepsy by medical examination. Among the 68 participants with epilepsy who had a CT scan, 20 patients were diagnosed with definitive or probable NCC for a proportion of 46.9% (95% confidence interval [CI] 30.2-64.1) in Batondo and 45.5% (95% CI 19.0-74.1) in Pabré. No cases of NCC were identified in Nyonyogo. SIGNIFICANCE: All the definitive and probable cases of NCC were from the two villages where pig breeding is common. Prevention policies intended to reduce the burden of epilepsy in this country should include measures designed to interrupt the life cycle of Taenia solium.

Enhancing Braden pressure ulcer risk assessment in acutely ill adult veterans.

This study sought to determine if a parsimonious pressure ulcer (PU) predictive model could be identified specific to acute care to enhance the current PU risk assessment tool (Braden Scale) utilized within veteran facilities. Factors investigated include: diagnosis of gangrene, anemia, diabetes, malnutrition, osteomyelitis, pneumonia/pneumonitis, septicemia, candidiasis, bacterial skin infection, device/implant/graft complications, urinary tract infection, paralysis, senility, respiratory failure, acute renal failure, cerebrovascular accident, or congestive heart failure during hospitalization; patient's age, race, smoking status, history of previous PU, surgery, hours in surgery; length of hospitalization, and intensive care unit days. Retrospective chart review and logistic regression analyses were used to examine Braden scores and other risk factors in 213 acutely ill veterans in North Florida with (n = 100) and without (n = 113) incident PU from January-July 2008. Findings indicate four medical factors (malnutrition, pneumonia/pneumonitis, candidiasis, and surgery) have stronger predictive value (sensitivity 83%, specificity 72%, area under receiver operating characteristic [ROC] curve 0.82) for predicting PUs in acutely ill veterans than Braden Scale total scores alone (sensitivity 65%, specificity 70%, area under ROC curve 0.70). In addition, accounting for four medical factors plus two Braden subscores (activity and friction) demonstrates better overall model performance (sensitivity 80%, specificity 76%, area under ROC curve 0.88).

Evaluation of Protective Properties of Commercially Available Medical Helmets: Are Medical Helmets Protective?

OBJECTIVES: The aims of the study were to evaluate and to compare protective properties of commercially available medical helmets for a set of standardized head injury risk measures. METHODS: Eleven helmet types were evaluated to represent the variety of commercially available medical helmet designs and manufacturers. A test mannequin and sensor apparatus were used to simulate a backward-standing fall. The head/neck size, mass, and "standing" height of the mannequin (5'9″) were representative of a 50th percentile male. A triaxial array was placed at the head center of mass to position 3 linear accelerometers and 3 angular rate sensors. Data were collected for 5 single trials for each helmet, as well as 5 repeated trials. Five trials were also collected with no helmet scenarios. Three head injury risk measures were examined (linear acceleration, angular acceleration, and head injury criterion). Data were analyzed by clinical cutoff thresholds and continuous values. RESULTS: Helmets varied in their performance across head injury risk measures. All helmets provided higher levels of protection compared with no helmet scenarios. No helmets were protective for subdural hematoma (measured by angular acceleration). All helmets lost protective properties with repeated falls. Results for skull fracture risk were inconsistent between linear acceleration and head injury criterion injury risk measures. CONCLUSIONS: No helmets were protective across all head injury risk measures. Medical helmets may reduce some fall injury severity but may not prevent all types of head injury. All helmets exhibited worsening of protective properties with repeated falls. We recommend medical helmets be replaced after each fall incident where the helmet impacts another surface.

Evaluation of a new assistive technology: the StandBar.

PURPOSE: Evaluate the potential of a wheelchair assistive technology (StandBar) to promote power wheelchair users' ability to safely stand independently from their power wheelchair and determine the impact of the device use on psychological well-being for both power wheelchair users and their caregivers. MATERIALS AND METHODS: A convenience sample of 11 power wheelchair users and caregiver dyads provided study data. Participants included power wheelchair users who were existing StandBar users or currently in training with the StandBar as part of their rehabilitation. Assessments were conducted at baseline and at six-month follow-up and included physiological assessments and functional testing with and without the StandBar. Monthly follow-up phone calls were completed to collect information on adverse events (e.g., falls, hospitalizations, and skin breakdown). A qualitative interview assessed StandBar users' and caregivers' perception at six-month follow-up. RESULTS AND CONCLUSIONS: StandBar use provided power wheelchair users a higher level of independence, confidence, and safety. All participants highly recommended StandBar use to others with similar levels of functional impairment. StandBar use allowed many participants the ability to complete functional tasks that were otherwise not possible without assistance. Qualitative interviews reported improved independence and psychological well-being for StandBar users as well as reduced levels of anxiety and burden of care by caregivers. The StandBar is a cost-effective assistive technology that promotes independence and functionality for power wheelchair users and improves the psychological well-being of users and their caregivers. Implications for RehabilitationStandBar allows power wheelchair users to:Minimize negative effects of immobilization.Increase independence for activities of daily living (grooming, hygiene, toileting, transfers) and instrumental activities of daily living (social experiences).Improve their quality of life through increasing independence and confidence.Reduce need for assistance and corresponding caregiver burden.

Factors at the scene of injury associated with air versus ground transport to definitive care in a state with a large rural population.

BACKGROUND: Once emergency medical services (EMS) personnel decide to transport a trauma patient directly to definitive care, the next key decision at the scene of injury is whether to transport by air or ground. OBJECTIVE: The aim of this study was to identify factors at the scene of injury that are associated with this decision. METHODS: All trauma patients transported directly to a level I or level II trauma center by either air or ground EMS over a four-year period were selected from the Oklahoma State Trauma Registry. Initial scene vital signs, Glasgow Coma Scale score (GCS), injury mechanism, anatomic triage criteria, age, time of day, ground EMS service level, and scene location were collected. Scene location ZIP code centroids were geocoded and used to calculate distance to the trauma center. Following bivariate analyses, multivariable logistic regression models were developed within three strata defined by distance (>35, 16-35, and <16 miles). RESULTS: More than 80% of the patients beyond 35 miles were transported by air, compared with 32% from 16-35 miles and only 4% from <16 miles. Regardless of distance, patients transported by helicopter tended to be younger, more often had abnormal vital signs, and more frequently came from areas served by a basic or intermediate ground EMS agency, as compared with patients transported by ground. Within each distance stratum, patients injured in severe motor vehicle crashes, motorcycle crashes, or pedestrian incidents were more likely to be transported by air. A GCS <14 was the only patient-related factor consistently associated with increased odds of air transport. CONCLUSION: Distance is the main factor in deciding whether to use air or ground EMS to transport a trauma patient from the scene of injury to a trauma center. With the exception of GCS <14, injury etiology was more strongly and consistently associated with the decision to transport by air than were patient related-factors. Identifying factors influencing the field transport decision will help develop transport guidelines that make efficient use of EMS resources.
