Palliative care experience of US adult nephrology fellows: a national survey

Palliative care (PC) training and experience of United States (US) adult nephrology fellows was not known. It was also not clear whether nephrology fellows in the US undergo formal training in PC medicine during fellowship. To gain a better understanding of the clinical training and experience of US adult nephrology fellows in PC medicine, we conducted a national survey in March 2012. An anonymous on-line survey was sent to US adult nephrology fellows via nephrology fellowship training program directors. Fellows were asked several PC medicine experience and training questions. A total of 105 US adult nephrology fellows responded to our survey (11% response rate). Majority of the respondents (94%) were from university-based fellowship programs. Over two-thirds (72%) of the fellows had no formal PC medicine rotation during their medical school. Half (53%) of the respondents had no formal PC elective experience during residency. Although nearly 90% of the fellows had a division or department of PC medicine at their institution, only 46.9% had formal didactic PC medicine experience. Over 80% of the respondent's program did not offer formal clinical training or rotation in PC medicine during fellowship. While 90% of the responding fellows felt most comfortable with either writing dialysis orders in the chronic outpatient unit, seeing an ICU consult or writing continuous dialysis orders in the ICU, only 35% of them felt most comfortable “not offering” dialysis to a patient in the ICU with multi-organ failure. Nearly one out of five fellows surveyed felt obligated to offer dialysis to every patient regardless of benefit. Over two-thirds (67%) of the respondents thought that a formal rotation in PC medicine during fellowship would be helpful to them. To enhance clinical competency and confidence in PC medicine, a formal PC rotation during fellowship should be highly considered by nephrology training community.     

Knowledge of the Costs of Diagnostic Imaging: A Survey of Physician Trainees at a Large Academic Medical Center

PurposeTo study the awareness of postgraduate physician trainees across a variety of specialties regarding the costs of common imaging examinations.MethodsDuring early 2016, we conducted an online survey of all 1,238 physicians enrolled in internships, residencies, and fellowships at a large academic medical center. Respondents were asked to estimate Medicare national average total allowable fees for five commonly performed examinations: two-view chest radiograph, contrast-enhanced CT abdomen and pelvis, unenhanced MRI lumbar spine, complete abdominal ultrasound, and unenhanced CT brain. Responses within ±25% of published amounts were deemed correct. Respondents were also asked about specialty, postgraduate year of training, previous radiology education, and estimated number of imaging examinations ordered per week.ResultsA total of 381 of 1,238 trainees returned complete surveys (30.8%). Across all five examinations, only 5.7% (109/1,905) of responses were within the correct ±25% range. A total of 76.4% (291/381) of all respondents incorrectly estimated every examination’s cost. Estimation accuracy was not associated with number of imaging examinations ordered per week or year of training. There was no significant difference in cost estimation accuracy between those who participated in medical school radiology electives and those who did not (P = .14). Only 17.5% of trainees considered their imaging cost knowledge adequate. Overall, 75.3% desire integration of cost data into clinical decision support and/or computerized physician order entry systems.ConclusionsPostgraduate physician trainees across all disciplines demonstrate limited awareness of the costs of commonly ordered imaging examinations. Targeted medical school education and integration of imaging cost information into clinical decision support / computerized physician order entry systems seems indicated.     

Gender Differences in Trajectories of Lower Extremity Function in Older Adults: Findings From the International Mobility in Aging Study

ObjectivesWe examined the lower extremity function trajectories of older men and women over 4 years and baseline predictors of these trajectories.DesignLongitudinal analysis of an international cohort study.Settings and participantsOlder adults from the International Mobility in Aging Study (IMIAS) aged between 65 and 74 years at baseline.MeasuresPhysical performance of the lower extremities was measured in 2012, with follow-ups in 2014 and in 2016, using the Short Physical Performance Battery (SPPB). Group-based trajectory analysis of physical performance by gender was performed. Multinomial logistic regression was used to derive relative risk ratios with 95% confidence intervals between the physical performance trajectories and the potential baseline predictors in men and women separately.ResultsThree physical performance trajectories were identified in men and women: high-stable (30.0% vs 35.5%), gradual functional decline (63.1% vs 54.3%), and rapid functional decline (6.9% vs 10.2%). Common baseline characteristics associated with memberships in the gradual functional decline and rapid functional decline trajectory groups in men and women were age, single marital status, and multiple chronic conditions (>3). Among men, depression was a strong predictor of the membership in the rapid functional decline trajectory group. Women in the rapid functional decline trajectory group were more likely to be obese, with feminine and undifferentiated gender roles, and have poor self-rated health at baseline.Conclusions/ImplicationsThere are gender differences in the physical performance trajectories and related factors among older adults. Programs aiming at preventing or slowing functional decline in old age should be sensitive to gender.     

Invasive Cardiologists Are Exposed to Greater Left Sided Cranial Radiation: The BRAIN Study (Brain Radiation Exposure and Attenuation During Invasive Cardiology Procedures)

ObjectivesThis study sought to determine radiation exposure across the cranium of cardiologists and the protective ability of a nonlead, XPF (barium sulfate/bismuth oxide) layered cap (BLOXR, Salt Lake City, Utah) during fluoroscopically guided, invasive cardiovascular (CV) procedures.BackgroundCranial radiation exposure and potential for protection during contemporary invasive CV procedures is unclear.MethodsInvasive cardiologists wore an XPF cap with radiation attenuation ability. Six dosimeters were fixed across the outside and inside of the cap (left, center, and right), and 3 dosimeters were placed outside the catheterization lab to measure ambient exposure.ResultsSeven cardiology fellows and 4 attending physicians (38.4 ± 7.2 years of age; all male) performed diagnostic and interventional CV procedures (n = 66.2 ± 27 cases/operator; fluoroscopy time: 14.9 ± 5.0 min). There was significantly greater total radiation exposure at the outside left and outside center (106.1 ± 33.6 mrad and 83.1 ± 18.9 mrad) versus outside right (50.2 ± 16.2 mrad; p < 0.001 for both) locations of the cranium. The XPF cap attenuated radiation exposure (42.3 ± 3.5 mrad, 42.0 ± 3.0 mrad, and 41.8 ± 2.9 mrad at the inside left, inside center, and inside right locations, respectively) to a level slightly higher than that of the ambient control (38.3 ± 1.2 mrad, p = 0.046). After subtracting ambient radiation, exposure at the outside left was 16 times higher than the inside left (p < 0.001) and 4.7 times higher than the outside right (p < 0.001). Exposure at the outside center location was 11 times higher than the inside center (p < 0.001), whereas no difference was observed on the right side.ConclusionsRadiation exposure to invasive cardiologists is significantly higher on the left and center compared with the right side of the cranium. Exposure may be reduced similar to an ambient control level by wearing a nonlead XPF cap. (Brain Radiation Exposure and Attenuation During Invasive Cardiology Procedures [BRAIN]; NCT01910272)
