Purpose
To analyze the utilization, indications, and outcomes of dual-energy computed tomography (DECT) gout imaging in clinical practice.Methods
This retrospective study was ethics approved. Radiology reports of DECT gout scans between 2007 and 2016 were analyzed for trends of utilization, referral pattern, indication, and diagnosis.Results
DECT gout referrals increased substantially (2007: 37; 2008: 72; 2016: 385; total: 1877). The largest number of referrals were from rheumatology (1160), emergency medicine (283), and family medicine (177). Most referrals (92%) were requested to aid an initial diagnosis of gout. Other reasons included estimating the disease burden (6%) or monitoring disease progression and effectiveness of treatment (2%). Rheumatology accounted for most referrals for the latter two reasons (81% and 97%). Imaging findings of urate presence were similar in referrals from rheumatology (62%), family medicine (62%), and other medical specialties (62%). The urate positive rates were slightly lower in referrals from emergency medicine (47%) and surgical specialties (41%). The most common differential diagnoses by referring specialties were calcium pyrophosphate dihydrate crystal deposition disease (CPPD) and other inflammatory or erosive arthritides (rheumatology, family medicine), CPPD and infections (other medical specialties), infections and fractures (emergency medicine), neoplasm and infections (surgical specialties).Conclusions
The increasing utilization of DECT for gout imaging validates its clinical value. Varying clinical presentation could explain differences of urate positive rates among specialties. Our results support a multispecialty collaborative approach to the diagnosis and management of gout, with direct access to DECT gout imaging provided to various physician specialties. 相似文献23.

OBJECTIVE: To assess the reliability of the physical examination of the hip in osteoarthritis (OA) among rheumatologists and orthopedic surgeons, and to evaluate the benefits of standardization. METHODS: Thirty-five physical signs and techniques were evaluated using a 6 x 6 Latin square design. Subjects with mild to severe hip OA, based on physical and radiographic signs, were examined in random order prior to and following standardization of physical examination techniques. For dichotomous signs, agreement was calculated as the prevalence-adjusted bias-adjusted kappa (PABAK), whereas for continuous and ordinal signs a reliability coefficient was calculated using analysis of variance. A PABAK >0.60 and a reliability coefficient >0.80 were considered to indicate adequate reliability. RESULTS: Adequate post-standardization reliability was achieved for 25 (71%) of 35 signs. The most highly reliable signs included true and apparent leg length discrepancy > or =1.5 cm; hip flexion, abduction, adduction, and extension strength; log roll test for hip pain; internal rotation and flexion range of motion; and Thomas test for flexion contracture. The standardization process was associated with substantial improvements in reliability for a number of physical signs, although minimal or no change was noted for some. Only 1 sign, Trendelenburg's sign, was highly unreliable post-standardization. CONCLUSION: With the exception of gait, a comprehensive hip examination can be performed with adequate reliability. Post-standardization reliability is improved compared with pre-standardization reliability for some physical signs. The application of these findings to future OA studies will contribute to improved outcome assessments in OA. 相似文献

Quality improvement (QI) as a clinical improvement science has been criticized for failing to deliver broad patient outcome improvement and for being a top‐down regulatory and compliance construct. These critics have argued that the focus of QI should be on increasing adherence to clinical practice guidelines (CPGs) and, as a result, should be consolidated into research structures with the science of evidence‐based medicine (EBM) at the helm. We argue that EBM often overestimates the role of knowledge as the root cause of quality problems and focuses almost exclusively on the effectiveness of care while often neglecting the domains of safety, efficiency, patient‐centredness, and equity. Successfully addressing quality problems requires a much broader, systems‐based view of health‐care delivery. Although essential to clinical decision‐making and practice, EBM cannot act as the cornerstone of health system improvement. 相似文献
