These findings would help to formulate prevention strategies to reduce the injury severity of motorcycle crashes in the developing countries.Acute thoracic aortic dissection is an uncommon, although not rare, life-threatening condition. With protean signs and symptoms that often suggest more common cardiac or pulmonary conditions, it can be difficult to diagnose. Ultrasound has proven useful in making the correct diagnosis. This case demonstrates that training gained using standard ultrasound machines can be easily and successfully adapted to newer handheld ultrasound devices. Volasertib molecular weight The examination technique using the handheld device is illustrated with photos and a video.DISCLOSURES Funding for this summary was contributed by Arnold Ventures, California Health Care Foundation, Harvard Pilgrim Health Care, and Kaiser Foundation Health Plan to the Institute for Clinical and Economic Review (ICER), an independent organization that evaluates the evidence on the value of health care interventions.

Despite their importance, adherence to these medications is low. Low adherence is linked to increased exacerbation rates, mortality rates, health care utilization, and, ultimately, increased costs. A drug adherence index (DAI) is a predictive modeling tool that identifies patients most likely to change adherence status so that they can be targeted for support programs. Optum has previously developed DAI tools for diabetes, hypertension, and high cholesterol. In this study, a COPD-specific DAI was developed. This DAI tool could be used to better target medication adherence support in patients with COPD, aiming to increase adherence. OBJECTIVES To develop a COPD-specific DAI using (a) enrollment, medical, and pharmacy variables and (b) only enrollment and pharmacy variables for potential application to pharmacy benefit managers and pharmacy plans. METHODS This was a retrospective observational study usng and critical revision of the report and approved submission of the manuscript. All authors had access to the results of the analyses, reviewed and edited the manuscript, approved the final draft, and were involved in the decision to submit the manuscript for publication. The data contained in the Optum database contain proprietary elements owned by Optum and, therefore, cannot be broadly disclosed or made publicly available at this time. The disclosure of these data to third parties assumes certain data security and privacy protocols are in place and that the third party has executed a license agreement that includes restrictive agreements governing the use of the data. Bengtson, Buikema, and Bankcroft are employees at Optum, and Schilling is a former employee of Optum; their employment was not contingent on this work. Optum was funded by GlaxoSmithKline to conduct the study. Stanford was an employee of GlaxoSmithKline at the time of this study and holds stock in GlaxoSmithKline.DISCLOSURES No funding supported the writing of this letter.

There is no current standard protocol for assessing ototoxicity in CF centers in the United States. OBJECTIVE To evaluate the cost-effectiveness of a pharmacist-implemented routine hearing screening for ototoxicity among pediatric patients using a clinically validated tablet audiometer to allow for earlier detection of hearing loss in an exploratory analysis. METHODS A Markov decision-analytic model was developed to assess the cost-effectiveness of implementing routine screening with monthly cycles over a 3-year time horizon. The model measured the difference in promptly detected hearing loss, delayed detected hearing loss, and undetected hearing loss, compared with current screening practices. Model inputs were obtained through a comprehensive literature review. Primary model outcomes included total health care costs and quality-adjusted life-years (QALYs) gained with a 3% hKline had no involvement in the study creation, analysis, or manuscript composition.

Some integrated health-systems specialty pharmacies (HSSPs) embed pharmacists in clinics and dispense medications from their internal pharmacies if included within the LDN. OBJECTIVE To assess access to dalfampridine in patients at an HSSP before and after gaining admission to the LDN. METHODS This study was conducted at Vanderbilt Specialty Pharmacy (VSP), an integrated HSSP at Vanderbilt University Medical Center (VUMC) with 2 clinical pharmacists embedded in the MS clinic. VSP gained access to the dalfampridine LDN on May 1, 2018, at which time the embedded pharmacists began to manage the comprehensive therapy initiation process. We performed a retrospective review of adult patients with MS who were prescribed dalfampridine from March 2010 todds of having a longer medication access time were significantly higher for pre-VSP prescriptions (OR = 83.219, P less then 0.001) and prescriptions whose PA was initially denied (OR = 9.50, P less then 0.001); 25-foot walk time was not significant (OR = 0.95, P = 0.277). CONCLUSIONS After obtaining access to dispense dalfampridine, the time to access therapy was reduced, suggesting that LDNs delay patient access to therapy at HSSPs. DISCLOSURES No funding was provided for this study. The authors have no conflicting interests to disclose. Preliminary results have been previously presented at the American Society of Health-Systems Pharmacy Midyear Meeting in December 2019, the Vanderbilt Health Systems Specialty Pharmacy Outcomes Research Summit in August 2020, and the National Association of Specialty Pharmacy Annual Meeting in September 2020.
