简介:目的:调查加拿大针灸从业人员对针灸治疗急性腰痛的有效性及相关费用的认识,从而确定针灸在急性腰痛治疗中的应用情况。方法:于1996年9月对安大咯加拿大针灸基金会的285名会员发放问卷,只对内科医生及理疗医生的反馈问卷进行统计分析。结果:281名符合条件的会员,197名完成了问卷(回收率70.1%),45.0%为内科医生,55.0%为理疗医生。其中87.0%的人过去使用过针灸疗法治疗急性腰痛,66.O%的人调查时正在使用,87.0%的人表示将来会继续使用。87.0%的反馈者认为针灸治疗急性腰痛是有效的,60.0%的人认为针灸疗法可以阻止急性腰痛的发展。针灸平均每次费用为$28,必需的平均治疗次数为5.7次。结论:多数反馈者对针灸治疗急性腰痛持肯定态度,他们在临床上也经常使用针灸疗法治疗此病。绝大多数反馈者认为针灸治疗急性腰痛是有效的。此外,超过一半的反馈者相信针灸可以阻止急性腰痛的病情发展。虽然本研究调查的针灸从业者坚信针灸治疗急性腰痛是有效的,但需要高质量的大样本调查予以验证。
简介:AbstractBackground:Our aim was to evaluate the sensitivity and specificity of the automated computer-based Alberta Stroke Program Early CT Score (e-ASPECTS) for acute stroke patients and compare the result with physicians at different levels.Methods:In our center, e-ASPECTS and 9 physicians at different levels retrospectively and blindly assessed baseline computed tomography (CT) images of 55 patients. Sensitivity, specificity, receiver-operating characteristic curves, Bland-Altman plots with mean score error, and Matthews correlation coefficients were calculated. Comparisons were made between the scores by physicians and e-ASPECTS with diffusion-weighted imaging (DWI) being the ground truth. Two methods for clustered data were used to estimate sensitivity and specificity in the region-based analysis.Results:In total, 1100 (55 patients × 20 regions per patient) ASPECTS regions were scored. In the region-based analysis, sensitivity of e-ASPECTS was better than junior doctors and residents (0.576 vs 0.165 and 0.111, p < 0.05) but inferior to senior doctors (0.576 vs 0.617). Specificity was lower than junior doctors and residents (0.883 vs 0.971 and 0.914) but higher than senior doctors (0.883 vs 0.809, p < 0.05). E-ASPECTS had the best Matthews correlation coefficient of 0.529, compared to senior doctors, junior doctors, and residents (0.463, 0.251, and 0.087, respectively).Conclusions:e-ASPECTS showed a similar performance to that of senior physicians in the assessment of brain CT of acute ischemic stroke patients with the Alberta Stroke Program Early CT score method.
