Background: Incidence studies of spinal cord injury (SCI) are important for health-care planning and epidemiological research. This review gives a quantitative update on SCI epidemiology worldwide through a statistical evaluation of incidence rates. Methods: A systematic review was conducted. For each study, the crude rate ratio was calculated and, when possible, age- and gender-adjusted incidence rate ratios with 95% CI were determined by direct adjustment or using Poisson regression. Results: Thirteen studies were included. Annual crude incidence rates in traumatic SCI varied from 12.1 per million in The Netherlands to 57.8 per million in Portugal. Compared to the Portuguese reference study, incidence rates showed a 3-fold variation, with the highest rates in Canada and Portugal. Most traumatic SCI studies showed a bimodal age distribution. The first peak was found in young adults between 15 and 29 years and a second peak in older adults (mostly ≧65 years). Motor vehicle accidents and falls were the most prevalent causes of injury accounting for nearly equal percentages. In contrast, another age pattern in non-traumatic SCI reflected steadily increasing incidence with advancing age. Conclusions: The results show significant variation in SCI incidence with changing epidemiological patterns. A trend towards increased incidence in the elderly was observed, likely due to falls and non-traumatic injury.

Spinal cord injury (SCI) leading to neurological deficits produces long-term effects that persist over a lifetime. Survival analysis of patients with SCI, at individual and population level, is important for public health management and the assessment of treatment achievements. The current study evaluated survival following traumatic and non-traumatic SCI worldwide. A systematic review was conducted, and all included papers were assessed for quality using a purposely designed assessment form. Survival data were presented in Kaplan-Meier curves and compared using the log-rank test. Sixteen studies were included of which 11 concerned traumatic SCI, four non-traumatic SCI, and one both. Crude standard mortality rates (SMRs) revealed that overall mortality in SCI is up to three times higher than in the general population. Survival rates were statistically significantly lower in non-traumatic SCI than in traumatic SCI (log-rank p = 0.000). Age at injury, neurological level, extent of lesion, and year of injury have been described as predictors of survival. Causes of death stem from secondary complications, with failure of the respiratory system being the leading cause. This is the first systematic literature review on survival analysis following SCI worldwide. An increase in survival over time was found. However, the SMRs of individuals with SCI still exceed those of an age-matched non-disabled population, mainly due to secondary complications. Lower survival rates were observed in non-traumatic SCI compared with traumatic SCI.

Background and Objectives Despite acknowledged benefits of residents in nursing homes spending time outdoors, little is known about factors related to their use of outdoor space. This systematic review summarizes reported barriers and enablers to nursing home residents’ use of outdoor spaces. Research Design and Methods Multiple databases were searched to May 2018. Qualitative or mixed methods studies describing barriers/enablers to use of outdoor areas by residents of nursing homes (aged 65 years and older), as reported by residents, staff, or family members were included. Study quality rating, thematic analysis, and stratified analyses were performed and confidence in findings assessed using GRADE-CERQual. Results Twenty-four studies were included. Nineteen collected data from residents, 15 from staff/caregivers, 7 from families. Major themes and key findings concerned: design of the outdoor area (importance of garden greenery and built features), safety concerns and staffing issues, weather and seasons (appropriate shade and shelter), design of the main building (easy to open doors and nearby access points) and social activities. Conclusions and Implications Providing gardens with seasonal plants and interactive features, weather protected seating, manageable doors at accessible thresholds, planned social activities, and appropriate clothing are fundamental to facilitate nursing home residents’ access to the outdoors. Cultural change at an organizational level, addressing perceptions of safety as a barrier is important. Incorporation of the recommendations in this review by architects, facility managers, and policy makers in the design and management of nursing homes, may increase use of outdoor areas and improve the quality of life of residents.
