Manual Wheelchair Skills Training for Community-Dwelling Veterans with Spinal Cord Injury: A Randomized Controlled Trial.

OBJECTIVES: To test the hypotheses that community-dwelling veterans with spinal cord injury (SCI) who receive the Wheelchair Skills Training Program (WSTP) in their own environments significantly improve their manual wheelchair-skills capacity, retain those improvements at one year and improve participation in comparison with an Educational Control (EC) group. METHODS: We carried out a randomized controlled trial, studying 106 veterans with SCI from three Veterans Affairs rehabilitation centers. Each participant received either five one-on-one WSTP or EC sessions 30-45 minutes in duration. The main outcome measures were the total and subtotal percentage capacity scores from the Wheelchair Skills Test 4.1 (WST) and Craig Handicap Assessment and Reporting Technique (CHART) scores. RESULTS: Participants in the WSTP group improved their total and Advanced-level WST scores by 7.1% and 30.1% relative to baseline (p < 0.001) and retained their scores at one year follow-up. The success rates for individual skills were consistent with the total and subtotal WST scores. The CHART Mobility sub-score improved by 3.2% over baseline (p = 0.021). CONCLUSIONS: Individualized wheelchair skills training in the home environment substantially improves the advanced and total wheelchair skills capacity of experienced community-dwelling veterans with SCI but has only a small impact on participation.

Wheelchair-related falls in veterans with spinal cord injury residing in the community: a prospective cohort study.

OBJECTIVES: (1) To determine the incidence of wheelchair falls and fall-related injuries in persons with spinal cord injury (SCI) living in the community. (2) To predict wheelchair-related falls and associated injuries from specific parameters including characteristics of the wheelchair user, wheelchair type and features, health care practices, wheelchair activities, and physical environment. DESIGN: This prospective cohort study followed participants monthly over 1 year; data were collected through surveys, interviews, performance testing, observation, and medical records. SETTING: Three Veterans' Administration hospitals. PARTICIPANTS: Convenience sample of community-dwelling persons with SCI who used a wheelchair as their primary means of mobility (N=702). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Self-reports of wheelchair falls and fall-related injuries, Wheelchair User Characteristics Survey, Health Status Checklist, Health-Related Behaviors, Zuckerman Sensation Seeking Scale, Wheelchair and Equipment-Related Behaviors, Wheelchair Characteristics, Wheelchair Skills Test, and Physical Environment Assessment. RESULTS: Of the 659 subjects who completed the study, 204 participants (31%) reported 553 fall events, and 95 subjects (14%) were injured as a result of wheelchair falls. A logistic regression model for predicting wheelchair falls identified 6 significant risk factors: pain in previous 2 months, alcohol abuse, greater motor function, history of previous fall, fewer SCI years, and shorter length of wheelchair. Eighty-two percent of the variance for wheelchair fall events was explained by these 6 variables. A logistic regression model for predicting injurious falls identified 4 significant risk factors: pain in previous 2 months, greater motor function, history of previous fall, and inaccessible home entrance. These 4 factors were able to explain 81% of the variance for injurious falls. CONCLUSIONS: This is the first study to determine the incidence of wheelchair-related falls in community-dwelling people with SCI who use a wheelchair. Results indicate the incidence of falls was 31% and injurious falls was 14%. Those at greatest risk can be predicted from some readily available information regarding their clinical status, wheelchair features, and home environment.

Longitudinal investigation of wandering behavior in Department of Veterans Affairs nursing home care units.

OBJECTIVES: To explore the extent of and factors associated with male residents who change wandering status post nursing home admission. DESIGN: Longitudinal design with secondary data analyses. Admissions over a 4-year period were examined using repeat assessments with the Minimum Data Set (MDS) to formulate a model understanding the development of wandering behavior. SETTING: One hundred thirty-four Veterans Administration (VA) nursing homes throughout the United States. PARTICIPANTS: Included 6673 residents admitted to VA nursing homes between October 2000 and October 2004. MEASUREMENTS: MDS variables (cognitive impairment, mood, behavior problems, activities of daily living and wandering) included ratings recorded at residents' admission to the nursing home and a minimum of two other time points at quarterly intervals. RESULTS: The majority (86%) of the sample were classified as non-wanderers at admission and most of these (94%) remained non-wanderers until discharge or the end of the study. Fifty-one per cent of the wanderers changed status to non-wanderers with 6% of these residents fluctuating in status more than two times. Admission variables associated with an increased risk of changing status from non-wandering to wandering included older age, greater cognitive impairment, more socially inappropriate behavior, resisting care, easier distractibility, and needing less help with personal hygiene. Requiring assistance with locomotion and having three or more medical comorbidities were associated with a decreased chance of changing from non-wandering to wandering status. CONCLUSION: A resident's change from non-wandering to wandering status may reflect an undetected medical event that affects cognition, but spares mobility.

Pressure ulcers and occipital alopecia in Operation Iraqi Freedom polytrauma casualties.

OBJECTIVE: Several of the casualties from Operation Iraqi Freedom arriving at one Veterans Administration (VA) polytrauma rehabilitation center (PRC) were noted to have occipital pressure ulcers or hair loss. The objective of this study was to determine the prevalence and severity of pressure-related injuries in VA PRC admissions. METHODS: A retrospective review of admissions from active duty from 2004 to 2006 was performed. RESULTS: Thirty-eight percent of admissions to this VA PRC had pressure-related injuries on the day of admission. Casualties from Iraq had a higher rate of pressure ulcers (53%) than did those from elsewhere (22%). Occipital lesions constituted 50% of non-stage I pressure ulcers and were more severe than those of the sacrum or extremities. CONCLUSIONS: Further epidemiological research should be performed to identify risk factors for pressure injury in the military continuum of care, by linking specific military medical evacuation and treatment processes and characteristics of casualties with outcomes.

Characterizing wandering behaviors in persons with traumatic brain injury residing in veterans health administration nursing homes.

OBJECTIVE: To examine the prevalence and correlates of wandering in persons with traumatic brain injury (TBI) in nursing homes (NHs). DESIGN: Using a cross-sectional design, logistic regression modeling was used to analyze a national database. SETTING: One hundred thirty-four NH facilities operated by the Veterans Health Administration. PARTICIPANTS: NH residents (N=625) with TBI as well as a sample (n=164) drawn from a larger dataset of NH residents without TBI using 1:K matching on age. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Wandering. RESULTS: Wanderers with and without TBI did not differ significantly overall. The prevalence of wandering among patients with TBI was 14%, compared with 6.5% of the general nursing home population. The results of the multivariate logistic regression suggested that wandering was associated with poor memory, poor decision making, behavior problems, independence in locomotion and ambulation, and dependence in activities of daily living related to basic hygiene. CONCLUSIONS: Wandering is relatively common in NH residents with TBI. As expected, it is associated with cognitive, social, and physical impairments. Further research with a larger sample should examine those with comorbid dementia and/or psychiatric diagnoses.

Health care costs for patients with chronic spinal cord injury in the Veterans Health Administration.

BACKGROUND/OBJECTIVE: Recurring annual costs of caring for patients with chronic spinal cord injury (SCI) is a large economic burden on health care systems, but information on costs of SCI care beyond the acute and initial postacute phase is sparse. The objective of this study was to establish a frame of reference and estimate of the annual direct medical costs associated with health care for a sample of patients with chronic SCI (ie, > 2 years after injury). METHODS: Patients were recruited from 3 Veterans Health Administration (VHA) SCI facilities; baseline patient information was cross-referenced to the Decision Support System (DSS) National Data Extracts (NDE) to obtain patient-specific health care costs in VHA. Descriptive statistical analysis of annual DSS-NDE cost of patients with SCI (N = 675) for fiscal year (FY) 2005 by level and completeness of injury was conducted. RESULTS: Total (inpatient and outpatient) annual (FY 2005) direct medical costs for 675 patients with SCI exceeded $14.47 million or $21,450 per patient. Average annual total costs varied from $28,334 for cervical complete SCI to $16,792 for thoracic incomplete SCI. Two hundred thirty-three of the 675 patients with SCI who were hospitalized over the study period accounted for a total of 378 hospital discharges, costing in excess of $7.19 million. This approximated a cost of outpatient care received of $7.28 million for our entire sample. CONCLUSIONS: The comprehensive nature of health care delivery and related cost capture for people with chronic SCI in the VHA provided us the opportunity to accurately determine health care costs for this population. Future SCI postacute care cost analyses should consider case-mix adjusting patients at high risk for rehospitalization.

Providers' perceptions of spinal cord injury pressure ulcer guidelines.

BACKGROUND/OBJECTIVE: Pressure ulcers are a serious complication for people with spinal cord injury (SCI). The Consortium for Spinal Cord Medicine (CSCM) published clinical practice guidelines (CPGs) that provided guidance for pressure ulcer prevention and treatment after SCI. The aim of this study was to assess providers' perceptions for each of the 32 CPG recommendations regarding their agreement with CPGs, degree of CPG implementation, and CPG implementation barriers and facilitators. METHODS: This descriptive mixed-methods study included both qualitative (focus groups) and quantitative (survey) data collection approaches. The sample (n = 60) included 24 physicians and 36 nurses who attended the 2004 annual national conferences of the American Paraplegia Society or American Association of Spinal Cord Injury Nurses. This sample drew from two sources: a purposive sample from a list of preregistered participants and a convenience sample of conference attendee volunteers. We analyzed quantitative data using descriptive statistics and qualitative data using a coding scheme to capture barriers and facilitators. RESULTS: The focus groups agreed unanimously on the substance of 6 of the 32 recommendations. Nurse and physician focus groups disagreed on the degree of CGP implementation at their sites, with nurses as a group perceiving less progress in implementation of the guideline recommendations. The focus groups identified only one recommendation, complications of surgery, as being fully implemented at their sites. Categories of barriers and facilitators for implementation of CPGs that emerged from the qualitative analysis included (a) characteristics of CPGs: need for research/evidence, (b) characteristics of CPGs: complexity of design and wording, (c) organizational factors, (d) lack of knowledge, and (e) lack of resources. CONCLUSIONS: Although generally SCI physicians and nurses agreed with the CPG recommendations as written, they did not feel these recommendations were fully implemented in their respective clinical settings. The focus groups identified multiple barriers to the implementation of the CPGs and suggested several facilitators/solutions to improve implementation of these guidelines in SCI. Participants identified organizational factors and the lack of knowledge as the most substantial systems/issues that created barriers to CPG implementation.

Wanderers with cognitive impairment in Department of Veterans Affairs nursing home care units.

OBJECTIVES: To explore the extent of and factors associated with male nursing home residents who wander. DESIGN: Cross-sectional design with secondary data analyses. SETTING: One hundred thirty-four nursing home facilities operated by the Department of Veterans Affairs. PARTICIPANTS: Fifteen thousand ninety-two nursing home residents with moderate or severe cognitive impairment admitted over a 4-year period. MEASUREMENTS: Selected variables from the Minimum Data Set included ratings recorded at residents' admission to the nursing home (cognitive impairment, mood, behavior problems, activities of daily living, and wandering). RESULTS: In this sample of residents with moderate or severe cognitive impairment, the proportion of wanderers was found to be 21%. Wanderers were more likely to exhibit severe (vs moderate) cognitive impairment, socially inappropriate behavior, resistance to care, use of antipsychotic medication, independence in locomotion or ambulation, and dependence in activities of daily living related to basic hygiene. A sizable proportion of wanderers were found to be wheelchair users (25%) or were wanderers with dual dementia and psychiatric diagnoses (23%), characteristics that are not well documented in the literature. CONCLUSION: These results support previous clinical understanding of wanderers to be those who are more likely to exhibit more-severe cognitive impairment. Based on a statistical model with variables generated from prior research findings, classification as a wanderer was found to be associated with other disruptive activity such as socially inappropriate behavior and resisting care. Two understudied populations of wanderers were documented: wheelchair wanderers and those with comorbid dementia and psychiatric diagnoses. Future longitudinal studies should examine predictors of wandering behavior, and further research should explore the understudied subpopulations of wheelchair and dual-diagnosis wanderers who emerged in this study.

Design and evaluation of a stand-up motorized prone cart.

BACKGROUND/OBJECTIVE: Prone carts are used for mobility by individuals with spinal cord injury in whom seated mobility (wheelchair) is contraindicated due to ischial or sacral pressure ulcers. Currently available prone carts are uncomfortable, subjecting the user to neck and shoulder strain, and make social interaction and performing activities of daily living difficult. A better design of prone carts is needed. In addition, standing devices have shown some medical benefits. The objective was to design and evaluate an improved prone cart that facilitates standing. DESIGN: Engineering development project with user feedback through questionnaire. Users selected by convenience sampling. METHODS: A marketing survey was performed of nurse managers of spinal cord injury units. Then 2 prototype carts were designed and built. These carts are able to tilt up to 45 degrees and have a joystick-controlled motor for propulsion and other design features, including a workspace storage shelf and rearview mirrors. The carts were evaluated by both patients and caregivers at 2 Veteran's Administration hospitals. OUTCOME MEASURES: Questionnaire of subjects, both patients and caregivers, who used the cart. FINDINGS: Both patients and caregivers liked the carts and the ability to assume a nonhorizontal body angle. The major complaint about the cart was that it seemed too long when it came to making turns. CONCLUSION: This prone cart design is an improvement over the standard, flat variety. However, further design changes will be necessary. This study provided valuable information that will be useful in the next-generation prone cart design project.

A multivariate fall risk assessment model for VHA nursing homes using the minimum data set.

OBJECTIVES: The purpose of this study was to develop a multivariate fall risk assessment model beyond the current fall Resident Assessment Protocol (RAP) triggers for nursing home residents using the Minimum Data Set (MDS). DESIGN: Retrospective, clustered secondary data analysis. SETTING: National Veterans Health Administration (VHA) long-term care nursing homes (N = 136). PARTICIPANTS: The study population consisted of 6577 national VHA nursing home residents who had an annual assessment during FY 2005, identified from the MDS, as well as an earlier annual or admission assessment within a 1-year look-back period. MEASUREMENT: A dichotomous multivariate model of nursing home residents coded with a fall on selected fall risk characteristics from the MDS, estimated with general estimation equations (GEE). RESULTS: There were 17 170 assessments corresponding to 6577 long-term care nursing home residents. The increased odds ratio (OR) of being classified as a faller relative to the omitted "dependent" category of activities of daily living (ADL) ranged from OR = 1.35 for "limited" ADL category up to OR = 1.57 for "extensive-2" ADL (P < .0001). Unsteady gait more than doubles the odds of being a faller (OR = 2.63, P < .0001). The use of assistive devices such as canes, walkers, or crutches, or the use of wheelchairs increases the odds of being a faller (OR = 1.17, P < .0005) or (OR = 1.19, P < .0002), respectively. Foot problems may also increase the odds of being a faller (OR = 1.26, P < .0016). Alzheimer's or other dementias also increase the odds of being classified as a faller (OR = 1.18, P < .0219) or (OR=1.22, P < .0001), respectively. In addition, anger (OR = 1.19, P < .0065); wandering (OR = 1.53, P < .0001); or use of antipsychotic medications (OR = 1.15, P < .0039), antianxiety medications (OR = 1.13, P < .0323), or antidepressant medications (OR = 1.39, P < .0001) was also associated with the odds of being a faller. CONCLUSIONS: This national study in one of the largest managed healthcare systems in the United States has empirically confirmed the relative importance of certain risk factors for falls in long-term care settings. The model incorporated an ADL index and adjusted for case mix by including only long-term care nursing home residents. The study offers clinicians practical estimates by combining multiple univariate MDS elements in an empirically based, multivariate fall risk assessment model.

Effectiveness of an evidence-based curriculum module in nursing schools targeting safe patient handling and movement.

Nursing schools in the United States have not been teaching evidence-based practices for safe patient handling, putting their graduates at risk for musculoskeletal disorders (MSDs). The specific aim of this study was to translate research related to safe patient handling into the curricula of nursing schools and evaluate the impact on nurse educators and students' intentions to use safe patient handling techniques. Nurse educators at 26 nursing schools received curricular materials and training; nursing students received the evidence-based curriculum module. There were three control sites. Questionnaires were used to collect data on knowledge, attitudes, and beliefs about safe patient handling for both nurse educators and students, pre- and post-training. In this study, we found that nurse educator and student knowledge improved significantly at intervention schools, as did intention to use mechanical lifting devices in the near future. We concluded that the curriculum module is ready for wide dissemination across nursing schools to reduce the risk of MSDs among nurses.

Friction-reducing devices for lateral patient transfers: a clinical evaluation.

The purpose of this study was to assess the performance of lateral transfer devices compared with the traditional draw sheet method in acute care settings through subjective feedback of caregivers actually using the devices. Every 2 weeks, the eight participating acute care units each received one of the devices, which had been randomly selected. Data were collected through caregiver surveys, which rated comfort, ease of use, perceived injury risk, time efficiency, and patient safety. An overall performance rating was calculated as the sum of these five categories. Caregivers rated air-assisted devices significantly higher (p < .05) than other devices. Lateral transfer devices are recommended over the traditional draw sheet method for performing lateral patient transfers. These friction-reducing devices are a cost-effective solution to the load of lateral patient transfers and should be favorably considered when purchasing patient-handling technologies.

Developing a quality measure for clinical inertia in diabetes care.

OBJECTIVE: To develop a valid quality measure that captures clinical inertia, the failure to initiate or intensify therapy in response to medical need, in diabetes care and to link this process measure with outcomes of glycemic control. DATA SOURCES: Existing databases from 13 Department of Veterans Affairs hospitals between 1997 and 1999. STUDY DESIGN: Laboratory results, medications, and diagnoses were collected on 23,291 patients with diabetes. We modeled the decision to increase antiglycemic medications at individual visits. We then aggregated all visits for individual patients and calculated a treatment intensity score by comparing the observed number of increases to that expected based on our model. The association between treatment intensity and two measures of glycemic control, change in HbA1c during the observation period, and whether the outcome glycosylated hemoglobin (HbA1c) was greater than 8 percent, was then examined. PRINCIPAL FINDINGS: Increases in antiglycemic medications occurred at only 9.8 percent of visits despite 39 percent of patients having an initial HbA1c level greater than 8 percent. A clinically credible model predicting increase in therapy was developed with the principal predictor being a recent HbA1c greater than 8 percent. There were considerable differences in the intensity of therapy received by patients. Those patients receiving more intensive therapy had greater improvements in control (p < .001). CONCLUSIONS: Clinical inertia can be measured in diabetes care and this process measure is linked to patient outcomes of glycemic control. This measure may be useful in efforts to improve clinicians management of patients with diabetes.

Implementation of clinical practice guidelines for prevention of thromboembolism in spinal cord injury.

BACKGROUND/OBJECTIVES: The purpose of this study was to determine whether publication of the "Prevention of Thromboembolism in Spinal Cord Injury" clinical practice guideline (CPG) changed patient management and whether adherence to CPG recommendations improved after a targeted implementation strategy. METHODS: Data were abstracted from medical records of 134 and 520 patients with acute and chronic spinal cord injury (SCI), respectively, from 6 Veterans Affairs medical centers over 3 time periods: prepublication (T1), preimplementation (T2), and postimplementation (T3) of the CPG. Targeted interventions were developed to address provider-perceived barriers to guideline adherence, based on findings from focus groups conducted at each site. The interventions incorporated two implementation strategies: standardized documentation templates/standing orders and social marketing/outreach visits. RESULTS: Use of the specified duration for pharmacologic prophylaxis increased from 60% to 65% to 75% of patients with acute SCI in T1, T2, and T3, respectively (P = 0.060 and 0.041 for T1 vs T2 and T2 vs T3, respectively). Rates of use for individual pharmacologic prophylaxis agents changed significantly over the course of the study, with use of low-molecular-weight heparin increasing from 7% in T1 to 42% in T3. Physical assessments for thrombosis on hospitalization days 1 and 30 improved between T2 and T3. Use of prophylaxis in chronically injured patients with new risk factors for thromboembolism increased from 16% to 31% to 34% during T1, T2, and T3 (P = 0.001 and 0.87, respectively). CONCLUSIONS: The CPG publication had only a modest effect on practice. Use of structured implementation further increased the adherence to some CPG recommendations for thromboembolism prophylaxis. Similar implementation strategies should be considered for CPG recommendations with low adherence and high potential for morbidity and mortality.

A comparison of patient outcomes and quality of life in persons with neurogenic bowel: standard bowel care program vs colostomy.

BACKGROUND/OBJECTIVE: The purpose of this study was to compare patient outcomes and quality of life for people with neurogenic bowel using either a standard bowel care program or colostomy. METHODS: We analyzed survey data from a national sample, comparing outcomes between veterans with spinal cord injury (SCI) who perform bowel care programs vs individuals with colostomies. This study is part of a larger study to evaluate clinical practice guideline implementation in SCI. The sample included 1,503 veterans with SCI. The response rate was 58.4%. For comparison, we matched the respondents with colostomies to matched controls from the remainder of the survey cohort. A total of 74 veterans with SCI and colostomies were matched with 296 controls, using propensity scores. Seven items were designed to elicit information about the respondent's satisfaction with their bowel care program, whereas 7 other items were designed to measure bowel-related quality of life. RESULTS: No statistically significant differences in satisfaction or quality of life were found between the responses from veterans with colostomies and those with traditional bowel care programs. Both respondents with colostomies and those without colostomies indicated that they had received training for their bowel care program, that they experienced relatively few complications, such as falls as a result of their bowel care program, and that their quality of life related to bowel care was generally good. However, large numbers of respondents with colostomies (n = 39; 55.7%) and without colostomies (n = 113; 41.7%) reported that they were very unsatisfied with their bowel care program. CONCLUSION: Satisfaction with bowel care is a major problem for veterans with SCI.

Provider adherence to implementation of clinical practice guidelines for neurogenic bowel in adults with spinal cord injury.

BACKGROUND/OBJECTIVES: Clinical Practice Guidelines (CPGs) have been published on a number of topics in spinal cord injury (SCI) medicine. Research in the general medical literature shows that the distribution of CPGs has a minimal effect on physician practice without targeted implementation strategies. The purpose of this study was to determine (a) whether dissemination of an SCI CPG improved the likelihood that patients would receive CPG recommended care and (b) whether adherence to CPG recommendations could be improved through a targeted implementation strategy. Specifically, this study addressed the "Neurogenic Bowel Management in Adults with Spinal Cord Injury" Clinical Practice Guideline published in March 1998 by the Consortium for Spinal Cord Medicine METHODS: CPG adherence was determined from medical record review at 6 Veterans Affairs SCI centers for 3 time periods: before guideline publication (T1), after guideline publication but before CPG implementation (T2), and after targeted CPG implementation (T3). Specific implementation strategies to enhance guideline adherence were chosen to address the barriers identified by SCI providers in focus groups before the intervention. RESULTS: Overall adherence to recommendations related to neurogenic bowel did not change between T1 and T2 (P = not significant) but increased significantly between T2 and T3 (P < 0.001) for 3 of 6 guideline recommendations. For the other 3 guideline recommendations, adherence rates were noted to be high at T1. CONCLUSIONS: While publication of the CPG alone did not alter rates of provider adherence, the use of a targeted implementation plan resulted in increases in adherence rates with some (3 of 6) CPG recommendations for neurogenic bowel management.

Patient dignity in persons with spinal cord injury.

Technology is changing the way nurses provide patient care in spinal cord injury. A key nursing concern is the impact of technology-assisted caregiving tasks (TACT) on the patients' sense of dignity. Despite frequent use of the term dignity in discussing treatment of persons with disabilities, there is a dearth of empirical research related to this topic. In particular, there have been few attempts to define the construct for the purposes of valid measurement. The purpose of this article is, therefore, to critically review the relevant literature on patient dignity with an aim toward eventual development and validation of a Dignity Assessment Tool.
