Spinal cord injury and development of pressure injury during acute rehabilitation in Norway: a national retrospective cross-sectional study.

STUDY DESIGN: A national, retrospective, cross-sectional study. OBJECTIVES: To analyze the prevalence of pressure injury (PI), and characteristics associated with PI development in the hospitalized population of persons with a newly acquired spinal cord injury (SCI) between 2004 and 2014. SETTING: All three specialized Spinal Cord Units in Norway. METHODS: Demographic data related to prevalence and potential risk factors were retrieved from the electronic medical record (EMR). Statistical analyses were performed, using IBM SPSS Statistics, version 23. RESULTS: We identified 1012 individuals with a new SCI. Mean age at injury was 48 years (SD 19). The period prevalence of PI was 16% (95% CI = 0.14-0.19), and identified PI associations were complete SCI (OR = 0.1), being injured abroad (OR = 2.4), bowel (OR = 13), and bladder (OR = 9.2) dysfunction; comorbidities like diabetes mellitus 1 (OR = 7.9), diagnosed depression (OR = 3.8), ventilator support (OR = 3.0), drug abuse (OR = 3.0), and concurrent traumatic brain injury (OR = 1.7). Individuals in the age group of 15-29 years had higher odds of PI compared with middle-aged individuals (45-59 years). CONCLUSION: PI is a serious complication after SCI. The association between depression or comorbidity and PI occurrence should be investigated more thoroughly. We recommend implementation of a simple follow-up program regarding observation and prevention of PI. Increased awareness of factors that could contribute to PI will help to focus on better prevention and early recognition of PI. This will contribute to more optimal rehabilitation.

Hospital based care at home; study protocol for a mixed epidemiological and randomized controlled trial.

BACKGROUND: Individuals with spinal cord injuries (SCI) are prone to pressure ulcers (PUs) because of the loss of sensorimotor function involved as well as increased skin moisture. Treatment of PU after SCI is complicated, involving different specialties and with need for long-lasting follow-up. This study should identify risk factors for PU after SCI, and find an effective and less time-consuming treatment for the condition among different available methods for follow-up. METHOD/DESIGN: The first part of this research project aims to investigate the prevalence of PU among persons with SCI based on an epidemiological design. The study will identify possible risk factors for acquiring PU. A questionnaire focusing on previous and present PUs will be sent to persons who suffered SCIs between January 2004 and January 2014. In the second part we will compare two different treatment regimens of PU through a randomized controlled pilot trial (RCT) where we will compare outpatient SCI follow-up in a hospital versus outpatient follow-up from the patient's home, using telemedicine (teleSCI) interventions. We will compare the healing of the PU in the two groups (usual care versus teleSCI). The Tissue, Infection, Moisture Edge (TIME) registration form, the Photographic Wound Assessment Tool (PWAT) and the change in the ulcer size will be used to monitor the healing. Changes in health-related quality of life (HRQoL) and the need for assistance will be assessed using the Five Dimensions European Quality of Life scale (EQ-5D), the generic Medical Outcomes Study 12-item Short Form Health Survey (SF-12) modified version, the International Spinal Cord Injury Quality of Life Data set (ISCI-QoL Data set), and the Spinal Cord Independence Measure scale, version III (SCIM III). In addition to primary outcome measures, a cost-benefit evaluation and an assessment of patient satisfaction and participation will be performed, using customized questionnaires. DISCUSSION: The first part of the research project will reveal the epidemiology of PU after SCI, and explore the risk factors. This part enables further prevention of PU after SCI and this information will be used in the follow-up RCT. Videoconferencing in the outpatient follow-up of persons with SCI and PU will change clinical routines and facilitate interdisciplinary collaboration, communication and competence exchange among participants of the health care services. Our research protocol allows comparing methods for interaction between medical specialists at hospitals, local caregivers in the community, next of kin, and persons with SCI and PU. The RCT should identify advantages as well as challenges in the management of PU in different follow-up settings. This study aims to identify risk factors for PU after SCI, and find an effective and less time consuming treatment for the condition among different available methods for follow- up.

Retinal nerve fibre layer attenuation: clinical indicator for vigabatrin toxicity.

PURPOSE: To investigate whether persistent visual field defects among patients exposed once to the antiepileptic drug vigabatrin (VGB) were associated with peripapillary retinal nerve fibre layer thickness (RNFLT) attenuation. METHODS: Nine individuals with partial epilepsy and VGB-attributed visual field loss (group 1; 18 eyes) and seven age- and gender-matched individuals with epilepsy and no previous VGB exposure (group 2; 14 eyes) were included in the study. Full-field 120 point screening perimetry out to 60 degrees from central fixation using the Humphrey Field Analyzer was performed. RNFLT was quantified by optical coherence tomography (OCT) using Fast RNFLT protocol, Stratus OCT (3.0) after pupillary dilation. The results from the right eye are presented in this article. RESULTS: Among the patients with VGB-attributed visual field loss, five patients had only peripheral field defect (group 1a) and the remaining four had advanced field defects both in the periphery and within 30° from central fixation (group 1b). None of the patients in the control group had manifest visual field loss. The mean RNFLT among the patients with VGB-attributed visual field loss was significantly attenuated compared to the controls [mean total RNFLT: group 1: 75.6 ± 12.7 µm, group 2: 103.5 ± 9.7 µm, mean difference 27.9 µm, (CI 15.9-39.9; p < 0.001)]. RNFLT values classified as borderline according to normative database (Stratus OCT) occurred more frequently among individuals with VGB-attributed visual field loss than in controls (frequency in group 1: 6/9; group 2: 0/7, p = 0.011). The nasal, superior and inferior quadrants of RNFLT in individuals with VGB-attributed visual field loss were significantly attenuated, while no difference was detected in temporal quadrants compared to controls. Both individuals with peripheral and those with advanced visual field losses in the VGB group had attenuated mean total RNFLT compared to controls (p = 0.006, p = 0.002, respectively). Occurrence of borderline classification of total RNFLT ≤5th percentile was more frequent among individuals with advanced visual field loss than among controls (p = 0.048). CONCLUSION: Persistent visual field loss attributed to VGB is associated with reduced peripapillary RNFLT and was detected both among patients with advanced and among patients with only peripheral visual field defects. Measurements of RNFLT with OCT might be considered as a diagnostic supplement in the follow-up of patients exposed to vigabatrin.
