Radiologic evaluation of fracture healing.

Skeletal Radiol 2019 Mar 21;48(3):349-361. Epub 2018 Sep 21.

While assessment of fracture healing is a common task for both orthopedic surgeons and radiologists, it remains challenging due to a lack of consensus on imaging and clinical criteria as well as the lack of a true gold standard. Further complicating this evaluation are the wide variations between patients, specific fracture sites, and fracture patterns. Research into the mechanical properties of bone and the process of bone healing has helped to guide the evaluation of fracture union. Development of standardized scoring systems and identification of specific radiologic signs have further clarified the radiologist's role in this process. This article reviews these scoring systems and signs with regard to the biomechanical basis of fracture healing. We present the utility and limitations of current techniques used to assess fracture union as well as newer methods and potential future directions for this field.

The Foundational Public Health Services as a Framework for Estimating Spending.

Am J Prev Med 2017 Nov 24;53(5):646-651. Epub 2017 Aug 24.

Department of Health Policy and Management, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland.

Introduction: In support of the nation's effort to address rising healthcare costs and improve healthcare outcomes, the National Academy of Medicine called for a minimum package of public health services available in every community to protect and improve population health and identification of the resources needed to make these services universally available. In response, the Foundational Public Health Services (FPHS) framework was developed to outline a basic set of public health programs and capabilities. Although the FPHS is considered a useful public health practice tool, cost estimation for providing the FPHS is in its infancy. This is in part due to inability to estimate total costs of individual public health services and programs. This research begins to address this knowledge gap.

Methods: FPHS formed the basis of a coding framework used in 2013-2016 to code 1.9 million U.S. Census Bureau State Finance non-hospital expenditure records from 49 states from 2000 to 2013. Results were used to develop estimates of state governmental FPHS spending.

Results: FPHS spending constituted 36% of total state governmental non-hospital health spending from 2008 to 2013. The largest proportion of FPHS spending was on maternal/child health and the smallest proportion of spending was on access and linkage to clinical care.

Conclusions: This research is an important step in response to the National Academy of Medicine's call for estimating the resources needed to provide the FPHS. Such estimates allow for spending comparisons across states and may inform future research to assess and evaluate FPHS spending impacts.

Retained fibrin sheaths: chest computed tomography findings and clinical associations.

J Thorac Imaging 2014 Mar;29(2):118-24

Departments of *Radiology §Medicine ∥Family and Social Medicine, Albert Einstein College of Medicine, Montefiore Medical Center, Bronx †Department of Radiology, Staten Island University Hospital, Staten Island, NY ‡Department of Radiology, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel.

Purpose: Fibrin sheaths may develop around long-term indwelling central venous catheters (CVCs) and remain in place after the catheters are removed. We evaluated the prevalence, computed tomographic (CT) appearance, and clinical associations of retained fibrin sheaths after CVC removal.

Materials And Methods: We retrospectively identified 147 adults (77 men and 70 women; mean age 58 y) who underwent CT after CVC removal. The prevalence of fibrin sheath remnants was calculated. Bivariate and multivariate analyses were performed to assess for associations between sheath remnants and underlying diagnoses leading to CVC placement; patients' age and sex; venous stenosis, occlusion, and collaterals; CVC infection; and pulmonary embolism.

Results: Retained fibrin sheaths were present in 13.6% (20/147) of cases, of which 45% (9/20) were calcified. Bivariate analysis revealed sheath remnants to be more common in women than in men [23% (16/70) vs. 5% (4/77), P=0.0018] and to be more commonly associated with venous occlusion and collaterals [30% (6/20) vs. 5% (6/127), P=0.0001 and 30% (6/20) vs. 6% (7/127), P=0.0003, respectively]. Other variables were not associated. Multivariate analysis confirmed the relationship between fibrin sheaths and both female sex (P=0.005) and venous occlusion (P=0.01).

Conclusions: Retained fibrin sheaths were seen on CT in a substantial minority of patients after CVC removal; nearly half of them were calcified. They were more common in women and associated with venous occlusion.
