patients in the year following hospitalization for a first ischemic, nonhemorrhagic stroke. Design: Retrospective analysis of administrative databases. Setting: The Health Authority of Florence (AUSL 10) and the Health Authority of Empoli (AUSL 11). Participants: Not provided. Interventions: Not applicable. Main Outcome Measures: Rehospitalization rates, total inpatient days, and death rates. Results: AUSL 11 has a population 28% the size of AUSL 10 and a budget 23% the size of AUSL 10. There are notable differences in rehabilitation services. During the year following the index admission, stroke patients in AUSL 11 have an average readmission rate of 1.51, an average of 17.35 inpatient days, and a 24% mortality rate. By comparison, stroke patients in AUSL 10 have an average readmission rate of 1.81, an average of 19.71 inpatient days, and a 19.4% mortality rate. Conclusions: Resources and utilization of acute care and rehabilitation vary between the health authorities, as does mortality. Key Words: Rehabilitation; Stroke. Poster 72: Cancelled. Poster 73 Effect of Vitamin C Supplementation on Stroke Recovery: A Case-Matched Control Study. M. Rabadi (Burke Rehabilitation Hospital, White Plains, NY), S. Lee, F. Rabadi. Disclosure: None declared. Objective: To determine the effectiveness of vitamin C supplementation on functional recovery in patients with recent ischemic stroke. Design: Retrospective, case-match control study. Setting: Acute rehabilitation unit. Participants: 46 patients with acute ischemic stroke. Intervention: Vitamin C at 1000mg daily. Interventions: Not applicable. Main Outcome Measures: Change in total FIM instrument score. Secondary outcome measures were discharge disposition and length of stay (LOS). Continuous, ordinal, and nominal variables were analyzed using the Student t test, Mann-Whitney U test, and chi-square analyses, respectively. Results: The mean demographic variables ⫾ SD for the vitamin C group (n⫽23) versus the placebo group (n⫽23) were as follows: age, 76⫾11 years versus 76⫾11 years (P⫽.84), male-to-female ratio, 13 to 10 versus 13 to 10 (P⫽1.0), onset to admission, 12⫾7 days versus 11⫾5 days (P⫽.38), and admission total FIM score, 41⫾18 versus 41⫾18 (P⫽.99). No significant differences were found in the change in total FIM score (20⫾13 vs 26⫾6; P⫽.20), LOS (21⫾9d vs 23⫾9d; P⫽.59), or discharge disposition (home/ institution, 9/10 vs 13/9; P⫽.60) for the 2 groups. Conclusions: Not provided. Key Words: Rehabilitation; Vitamin C. Poster 74 The Efficacy of Electric Stimulation in the Healing of Stages III and IV Pressure Ulcers: A Literature Review. James A. Kehinde (Widener University, Chester PA). Disclosure: None declared. Objectives: To review available literatures on the efficacy of electric stimulation in the treatment of stages III and IV pressure ulcers and to counter the Center for Medicare & Medicaid Services requirement of waiting for 30 days of documented nonhealing of these ulcers with conventional treatment prior to initiation of electric stimulation. Data Sources: Literature review of studies from 1969 to present on Medline and CINAHL, using search terms electrotherapy or electrical stimulation, cross-referenced with pressure ulcers or skin wound or skin ulcers. Meta-analysis, systemic reviews, and clinical trials were reviewed. Study Selection: 196 articles were reviewed, and 10 met the criteria for inclusion in the review. Data Extraction: Must have stages III and IV pressure ulcers, must compare electric stimulation with traditional wound care methods, and must study human subjects. Data

Synthesis: When wound progress was measured in percentages, 5 articles reported 15% to 27% faster rates than traditional methods; 1 article reported 48%, with 11% in the control group; and 1 article did not give actual percentages. When wound progress was reported as rate of healing, 3 articles gave 1.5 to 2.5 times faster rates of healing compared with conventional wound treatment method. Conclusions: Electric stimulation significantly increased the rate of pressure ulcer healing. Physical therapists should determine when to initiate treatment because the literature shows that electric stimulation can have positive effect on pressure ulcer healing as early as 5 days postonset.

Soong-Nang Jang (Seoul National University, Korea), Wan-Ho Kim, Kyu-Bum Lee, Seon-Ja Rhee, Jae-Young Lim. Disclosure: None declared. Objective: To develop a collaborative model for community-based rehabilitation (CBR) in Korea. Design: Cross-sectional and randomized community trial (16 CBR programs for 12mo). Setting: 16 regions with CBR programs. Participants: Disabled persons (N⫽578) who had severe disability; 71 severely disabled persons participated in CBR. Practitioners (n⫽20) in each regions. Interventions: We performed 3 sections of research in order to consider multiple aspects: needs of persons with disabilities, evaluation of experimental CBR programs, and CBR workers’ opinions about collaboration. Main Outcomes Measures: Needs of rehabilitation services, quality of life (QOL) as measured by the SF-8, social support as measured by medical outcomes social support, Modified Barthel Index of activities daily living, and self-rated health. Results: Among 578 persons with disabilities in the communities, only 12% had used the rehabilitation care continuously. There were a total of 475 subprograms in the 16 regions for 3 years (2000⫺2002). After 12 months, the social support level of persons with disabilities improved significantly. The CBR programs that were more collaborative by design—that had an interdisciplinary service team and program coordinator—were more effective at improving the QOL of persons with disabilities. We surveyed CBR workers about their attitudes, problems, and strategies for collaborative activities in CBR. If managers had positive perceptions about collaboration, then this had a positive affect on collaboration activity. If there was less communication with other professionals and an absence of the committee for CBR, this had a negative impact on collaboration activities. Conclusions: Key components of the collaboration model for CBR were an interdisciplinary service team, a program coordinator, a community rehabilitation committee, formal and open communication between regional health and other sectors, and positive perception of managers. The roles of CBR committees may be as a link to community rehabilitation programs and as a resource to evaluate community resources and functional status of disabled persons.

sure social participation and resources as predictors of QOL and depression after TBI. Setting: Community. Participants: Convenience sample of 490 persons with TBI. Interventions: Not applicable. Main Outcome Measures: Living Life After TBI, QOL rating scale (Life–3), and Beck Depression Inventory–II. Results: Among participants with mild TBI, social interaction with friends correlated negatively with depression (P⫽.025) and living alone at the time of injury was related to worse QOL postinjury (P⫽.005). These relationships were not statistically significant among those with moderate to severe TBI. Postinjury income level predicted both QOL and depression after TBI (P⫽.011). Preinjury religious involvement and marital status did not predict postinjury QOL or depression. Conclusions: Social support may play a larger role in the recovery of people with mild TBI than those with more severe TBI. Postinjury income may also play a role in outcomes. Key Words: Brain injuries; Rehabilitation. Poster 77 Traumatic Brain Injury Acute Rehabilitation Medical Severity Models. R. Seel (Shepherd Center, Atlanta, GA), D. Kaelin, R. Emory, S. Macciocchi. Disclosure: None declared. Objective: To develop medical complexity models to identify injury severity, physiologic, motor, cognitive, and psychologic factors that have the most impact on traumatic brain injury (TBI) acute rehabilitation outcomes. Design: Retrospective cohort. Correlation, analyses of variance, and stepwise multivariate regression analyses were calculated. Setting: Single-center, acute TBI rehabilitation unit. Participants: Demographically diverse sample of 521 persons who received at least 5 days of acute rehabilitation for moderate to severe TBI. Interventions: Not applicable. Main Outcome Measures: Acute rehabilitation length of stay (LOS) and FIM instrument motor and cognitive scores. Results: Medical complexity models based solely on case-mix group variables accounted for less than 50% of the variance in regression models of acute rehabilitation LOS, FIM motor, and FIM cognitive total scores. An evaluation of more than 200 injury severity, physiologic, motor, cognitive, and psychologic factors at admission and worst rating during rehabilitation stay yielded 3 medical complexity models that accounted for well over 65% of the variance for acute rehabilitation LOS and FIM motor and FIM cognitive total scores. Conclusions: Comprehensive models of TBI medical complexity can be identified that account for the overall severity of persons who receive acute rehabilitation. Key Words: Brain injuries; Rehabilitation.
vere stroke patients (community discharge rate, 47%) were discharged to the community than nonsevere stroke patients (community discharge rate, 77%) (P⬍.000). Among severe stroke patients, significant differences in community discharge rate were found across different census regions of the United States (P⬍.000). Conclusions: Overall, severe stroke patients have a dramatically lower probability of returning to the community from an IRF than nonsevere stroke patients; however, the community discharge rate among these patients varies widely across different regions of the country. Further research is suggested to examine the variation in regional community discharge rates for severe stroke patients. Key Words: Rehabilitation; Stroke.
