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.

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.

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.

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.

Iterative design and evaluation of new prone carts for individuals with SCDs: a technical note.

This paper summarizes a series of projects funded since 1992 to address the compelling need to improve the quality of life for persons with spinal cord dysfunctions who use prone carts. Specifically, Veterans Services Organization, National Institute on Disability and Rehabilitation Research (NIDRR), and the VA Rehabilitation Research and Development funded studies to develop new consumer-driven designs for prone carts. Using an iterative approach, this team of clinicians and designers (1) evaluated existing prone carts; (2) designed a new manual prone cart; (3) designed a new motorized prone cart, including a standing model; and (4) are collaborating with manufacturers to market and commercialize the new prone carts. Prototypes were developed at the Milwaukee Institute of Art and Design with the assistance of Ortho-Kinetics, Inc., and Everest & Jennings and were clinically evaluated at two Veterans Affairs Medical Centers (Tampa and Milwaukee) with patients and caregivers and for compliance with applicable ISO (International Organization for Standardization) for electric wheelchair standards.
