ABSTRACT

OBJECTIVE: Screening for abdominal aortic aneurysms (AAAs) reduces aneurysm-related mortality and has been recommended by the U.S. Preventive Services Task Force and American Heart Association since 2005. Medicare has covered a one-time screening ultrasound for new male enrollees with a familial or smoking history since 2007. Nevertheless, in the U.S., screening has remained underutilized. Review of patients with ruptured AAA in our system in 2007 showed the majority were undiagnosed, yet met U.S. Preventive Services Task Force and American Heart Association screening guidelines. To reduce the number of preventable AAA ruptures and deaths in our patients, we implemented an AAA screening program using our electronic medical record (EMR). This study describes the design, implementation, and early results of that screening program. METHODS: Between March 2012 and June 2013, men aged 65 to 75 years with any history of smoking were targeted for screening. Medical records were reviewed electronically to exclude patients with abdominal imaging studies within 10 years that would have diagnosed an AAA. Best practice alerts (BPA) were created in the EMR so when an appropriate patient is seen, office staff and providers are prompted to order an aortic ultrasound. AAA was defined as aortic diameter ≥3.0 cm or greater, and ultrasound reports contained a standard template providing guidance for patient management when an aneurysm was identified. Newly identified AAAs were triaged for vascular surgery consultation or follow-up with their primary physician. The number of eligible patients, unscreened patients, and AAAs identified were tabulated by our Regional Outpatient Safety Net Program. RESULTS: In a population of 3.6 million, 55,610 patients initially met screening criteria, and 26,837 (48.26%) were excluded from the BPA because of prior abdominal imaging studies. After 15 months, there were 68,164 patients who met screening criteria, 54,356 (79.74%) of whom had undergone an abdominal imaging study. Thus, 27,519 patients underwent an imaging study after the BPA was activated. During the study period, 731 new AAAs were diagnosed, 165 over 4.0 cm in diameter. Screening rates have increased at all medical centers where the BPA was activated, and the percentage of unscreened patients has been reduced from 51.74% to 20.26% system-wide. CONCLUSIONS: In an integrated health care system using an EMR, AAA screening can be implemented with a dramatic reduction in unscreened patients. Further analysis is required to assess the impact of the screening program on AAA rupture rate and cost-effectiveness in our system.

ABSTRACT

BACKGROUND: The ability of the Sensory Organization Test (SOT) to detect subtle balance problems has been challenged. The Head-Shake Sensory Organization Test (HS-SOT) has been developed to improve the delineation of balance performance. OBJECTIVE: The purposes of this study were: (1) to examine age-related differences in balance measured with the HS-SOT and (2) to establish the test-retest reliability of the HS-SOT in younger adults who were healthy and older adults who were healthy. DESIGN: A test-retest design was used in this observational measurement study. METHODS: Ninety-two younger adults who were healthy (mean age=28.3 years) and 73 older adults who were healthy (mean age=60.3 years) underwent the SOT and the HS-SOT. Seventy-seven of them (56 younger adults, 21 older adults) underwent the same assessments 1 to 2 weeks later. RESULTS: The equilibrium scores in HS-SOT conditions 2 (head movements with eyes closed while standing on a firm surface) and 5 (head movements with eyes closed while standing on a sway-referenced surface) were significantly lower than those in tests without dynamic head movements added (SOT conditions 2 and 5). Older adults attained significantly lower scores in both HS-SOT conditions than their younger peers. The test-retest reliability values, reported as intraclass correlation coefficients (ICC [3,2]), of the HS-SOT scores in conditions 2 and 5 for the younger adults were .85 and .78, respectively; those for the older adults were .64 and .55, respectively. The corresponding minimal detectable change values for the former were 2.7 and 16.2, and those for the latter were 3.6 and 22.7. LIMITATIONS: Only head rotation movements on the horizontal plane were tested. CONCLUSIONS: Adding head movements to the SOT increased the separation of younger adults who were healthy and older adults who were healthy. The HS-SOT has good reliability, and the reported minimal detectable change values may facilitate the interpretation of clinical studies in which the HS-SOT is used to assess changes in balance performance in younger and older adults.
