Objective: To identify barriers to access healthcare services and reveal determinants of satisfaction with healthcare services in people with chronic spinal cord injury (SCI).Design: Cross-sectional survey.Setting: Community setting in Switzerland.Participants: People with chronic SCI.Interventions: Non-applicable.Outcome Measures: Questionnaire-based evaluation of availability and quality of healthcare services for secondary health conditions, satisfaction with fulfillment of healthcare needs, and preference for care from a hypothetical service provider with limited specialized SCI care expertise but in close proximity over comprehensive care from an existing specialized SCI center located at a greater distance.Results: Close to three-quarter of participants (70%) indicated satisfaction with healthcare services received for SCI related health conditions. Elderly individuals (61+ years old) rated the availability and quality of healthcare 6% to 11% higher than younger individuals. The perceived fulfillment of healthcare needs was lower in people with incomplete paraplegia (odds ratio (OR) 2.11, 95%-credibility interval (CI) 1.18–3.84), chronic pain (OR 1.85, CI 1.12–3.08), insufficient access to long distance transportation (OR 5.81, CI 2.74–12.82), and longer travel distances to specialized SCI centers.Conclusion: Perceived inadequateness of access to healthcare services was partly related to transportation barriers, suggesting that outreach services or support with transportation are possible solutions. People with incomplete paralysis and pain consistently rated the fulfillment of care needs associated with SCI less favorably, pointing to the need for enhanced advocacy for this vulnerable groups. 相似文献

Background
Rhabdomyosarcoma is the most common malignant tumor in the nasal and paranasal sinus area at childhood. Multimodal treatment for this disorder has severe side effects due to normal tissue damage. As a result of this treatment, facial growth retardation and oral abnormalities such as malformation of teeth and microstomia can cause esthetic and functional problems. 相似文献996.

BackgroundComputed tomography (CT) scan is the standard for assessment of femoral torsion. This observational study was conducted to evaluate the comparability of the EOS radiation dose scanning system (EOS imaging, Paris, France) and the CT scan in patients with suspected torsional malalignment of the femur.MethodsPatients with suspected torsional malalignment of the femur were included in a study for surgical planning. The primary endpoint was to compare the 3-dimensional radiological (EOS) imaging system with the CT scan to determine femoral anteversion (AV) angle. Three independent raters performed measurements. Comparability of CT scan and EOS values was assessed by Pearson correlation, t test, interobserver reliability, and intraobserver reliability (Cronbach alpha).ResultsAbout 34 femora were examined. Interobserver reliability/intraobserver reliability was 0.911 of 0.955 for EOS and 0.934 of 0.934 for CT scan. EOS system revealed an AV angle of 12.2° ± 10.0° (?15.0° to 32.0°). CT examinations showed an AV angle of 12.6° ± 9.2° (?3.2° to 35.6°). About 11 hips featured physiological AV, 14 hips showed decreased AV (<10°) or retroversion (<0°), and 9 hips showed increased AV (>20°). Overall, a strong Pearson correlation of τ = 0.855 and a highly significant correlation in the t test for both methods was seen. In patients with decreased AV, retroversion, or increased AV, Pearson correlation only resulted in a moderate/low correlation of τ = 0.495 and τ = 0.292. The t test showed no significant correlation at malrotation.ConclusionIn torsional malalignment, EOS does not have correlation with CT measurements. In contrast to CT scan, EOS allows femoral torsion measurement independent of legs' positioning. 相似文献
