Design and Haemodynamic Analysis of a Novel Anchoring System for Central Venous Pressure Measurement.

BACKGROUND/OBJECTIVE: In recent years, treatment of heart failure patients has proved to benefit from implantation of pressure sensors in the pulmonary artery (PA). While longitudinal measurement of PA pressure profoundly improves a clinician's ability to manage HF, the full potential of central venous pressure as a clinical tool has yet to be unlocked. Central venous pressure serves as a surrogate for the right atrial pressure, and thus could potentially predict a wider range of heart failure conditions. However, it is unclear if current sensor anchoring methods, designed for the PA, are suitable to hold pressure sensors safely in the inferior vena cava. The purpose of this study was to design an anchoring system for accurate apposition in inferior vena cava and evaluate whether it is a potential site for central venous pressure measurement. MATERIALS AND METHODS: A location inferior to the renal veins was selected as an optimal site based on a CT scan analysis. Three anchor designs, a 10-strut anchor, and 5-struts with and without loops, were tested on a custom-made silicone bench model of Vena Cava targeting the infra-renal vena cava. The model was connected to a pulsatile pump system and a heated water bath that constituted an in-vitro simulation unit. Delivery of the inferior vena cava implant was accomplished using a preloaded introducer and a dilator as a push rod to deploy the device at the target area. The anchors were subjected to manual compression tests to evaluate their stability against dislodgement. Computational Fluid Dynamics (CFD) analysis was completed to characterize blood flow in the anchor's environment using pressure-based transient solver. Any potential recirculation zones or disturbances in the blood flow caused by the struts were identified. RESULTS: We demonstrated successful anchorage and deployment of the 10-strut anchor in the Vena Cava bench model. The 10-strut anchor remained stable during several compression attempts as compared with the other two 5-strut anchor designs. The 10-strut design provided the maximum number of contact points with the vessel in a circular layout and was less susceptible to movement or dislodgement during compression tests. Furthermore, the CFD simulation provided haemodynamic analysis of the optimum 10-strut anchor design. CONCLUSIONS: This study successfully demonstrated the design and deployment of an inferior vena cava anchoring system in a bench test model. The 10-strut anchor is an optimal design as compared with the two other 5-strut designs; however, substantial in-vivo experiments are required to validate the safety and accuracy of such implants. The CFD simulation enabled better understanding of the haemodynamic parameters and any disturbances in the blood flow due to the presence of the anchor. The ability to place a sensor technology in the vena cava could provide a simple and minimally invasive approach for heart failure patients.

Patient Satisfaction With Extended International Normalized Ratio Follow-up Intervals in a Veteran Population.

Background: For highly stable warfarin patients, limited data exists regarding patient satisfaction on extended international normalized ratio (INR) follow-up intervals and how this population compares with patients on a direct oral anticoagulant (DOAC). Objective: To assess the impact on patient satisfaction of extending INR follow-up intervals. Methods: Veterans on stable warfarin doses had extended INR follow-up intervals up to 12 weeks in a single-arm prospective cohort study for 2 years. This analysis included participants who completed at least 2 Duke Anticoagulation Satisfaction Scales (DASS). The primary outcome was the change in the DASS. A focus group described participant experiences. Participant satisfaction was compared to patients on a DOAC. Results: Of the 51 participants, 48 were included in the warfarin extended INR follow-up group. Compared with baseline, the mean DASS score (42.9 ± 12.08) was worse at 24 months (46.82 ± 15.2, P = 0.0266), with a small effect size (Cohen's d = 0.29). The 8 participants in the focus group were satisfied with the extended INR follow-up interval but would be uncomfortable extending follow-up past 2 to 3 months. The extended INR follow-up interval study had similar DASS scores as the 33 participants included on DOAC therapy (46.8 ± 15.1, P = 0.9970) but may be limited by differing populations using DOACs. Conclusion and Relevance: For patients currently stable on warfarin therapy, extending the INR follow-up interval up to 12 weeks or changing to a DOAC does not appear to improve patient satisfaction.

Feasibility and safety of a 12-week INR follow-up protocol over 2 years in an anticoagulation clinic: a single-arm prospective cohort study.

The 2012 American College of Chest Physicians' guidelines recommended a 12-week INR follow-up interval may be appropriate for patients on stable warfarin doses. Limited evidence supports this recommendation. A single-arm, prospective cohort study over 24 months was completed in a Veterans Affairs anticoagulation clinic to determine the long-term feasibility and safety of implementing an extended INR follow-up interval in Veterans on stable doses of warfarin. Participants were required to have a stable warfarin dose for 6 months prior to enrollment. A prespecified protocol was used to titrate, extend, and manage the INR interval up to 12 weeks. Scheduling of extended INR intervals was a primary outcome. Safety outcomes included major and serious bleeding and thromboembolic events. A post-hoc comparison of baseline characteristics between individuals who were scheduled for at least 4 consecutive 12-week INR follow-up intervals and those who were not was completed. Of the 50 participants, 36 (72%) were scheduled for at least one 12-week interval and 15 (30%) were scheduled for 4 consecutive intervals. There were 2 thromboembolic events that occurred in 1 participant. There were 28 major and serious bleeding events in 19 participants; 8 occurred while on the extended INR interval. In the post-hoc analysis, no participants scheduled for 4 consecutive 12-week intervals had heart failure. Based on 2 years of monitoring, a 12-week INR follow-up interval using a detailed protocol with titration of INR interval extension appears feasible for a subset of patients. Patients with heart failure may not be suitable for this intervention.

A novel method to measure mitral valve area in patients with rheumatic mitral stenosis using three-dimensional transesophageal echocardiography: Feasibility and validation.

AIMS: Neither two- nor three-dimensional (3D) planimetry of the mitral valve (MV) orifice takes the mitral commissures into account. Thus, if the commissures are not completely fused, the MV orifice will not be planar, and MV area (MVA) will be underestimated. The study aimed to validate a novel method for measurement of the MVA using a software that traces the MV orifice including the commissures. METHODS AND RESULTS: The study included 30 patients undergoing percutaneous balloon mitral valvuloplasty for severe rheumatic mitral stenosis. All performed 3D transesophageal echocardiography (TEE) immediately before the procedure. MVA was measured using the mitral valve navigation (MVN) software of the Philips Q-Lab 10.2 in a diastolic frame with maximum diastolic opening of the MV. Regular 3D planimetry of the MV orifice was also performed. Before balloon dilation, the MVA was calculated invasively using the Gorlin's formula. No significant difference was detected between MVN-derived MVA and Gorlin-derived MVA (0.98 cm2 vs. 1.0 cm2 , P = .33). A statistically significant difference was detected between Planimetry-derived MVA and Gorlin-derived MVA (0.8 cm2 vs. 1.0 cm2 , P < .001). There were significant linear correlations between MVN-derived MVA and Gorlin-derived MVA (r = .84, P < .001). Using Bland-Altman analysis, Gorlin-derived MVA showed better and relatively narrower limits of agreement with MVN-derived MVA than planimetry-derived MVA. CONCLUSION: Measurement of the MVA using the MVN method is feasible and is more correlated to the invasively measured MVA than the 3D planimetry method. This is the most accurate method of measuring the MVA that takes MV commissures into account.

Thermoreversible partitioning of poly(ethylene oxide)s between water and a hydrophobic ionic liquid.

We describe a poly(ethylene oxide) (PEO) homopolymer "shuttle" between water and a hydrophobic ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM][TFSI]). PEO homopolymers with varying molecular weight transferred reversibly and quantitatively between water at room temperature and [EMIM][TFSI] at an elevated temperature. The temperature of the transfer from water to [EMIM][TFSI] shows a linear dependence on PEO molecular weight and a dependence on polymer concentration consistent with expectation based on Flory-Huggins theory. These results are also consistent with the previously observed lower critical solution temperature (LCST) behavior of PEO in water. Dynamic light scattering study of the concentration and temperature dependence of the swelling degree of PEO corona of polybutadiene (PB)-PEO block copolymer micelles indicates that the solvent quality of [EMIM][TFSI] for PEO remains essentially the same as a good solvent over the temperature range of the PEO shuttle. Fundamental understanding of the PEO shuttle is of significance in development of systems for phase transfer of reagents and reaction products between ionic liquids and water.

Implementation of a Pharmacist-Driven Aspirin Deprescribing Protocol Among Older Veterans in a Primary Care Setting.

Background Recent cardiovascular guideline updates recommend against the use of aspirin for primary prevention of atherosclerotic cardiovascular disease (ASCVD) in older people. However, aspirin use remains common in this population. Objective To implement and evaluate the benefit of a pharmacist-driven aspirin deprescribing protocol compared with primary care provider (PCP) education-only in a primary care setting. Methods This prospective, cohort project targeted deprescribing for patients prescribed aspirin for primary prevention of ASCVD. Patients were included if they received primary care services at the Milwaukee Veterans Health Administration Medical Center (VHA) and were 70 years of age or older. Criteria for exclusion were aspirin obtained outside the VHA system, aspirin prescribed for a non-ASCVD-related condition, and/or a history of ASCVD. Active deprescribing by pharmacists and PCP education took place in the intervention group with PCP education only in the standard-of-care group. The primary outcome was the proportion of patients who had aspirin deprescribed in each group. Secondary outcomes included patient acceptability of the intervention and barriers to implementation. Results A total of 520 patients were prescribed aspirin in the intervention group versus 417 in the education-only group. Sixty-five patients met intervention criteria and were contacted for aspirin deprescribing. The pharmacist-led active deprescribing group led to a higher rate of aspirin deprescriptions versus the education-only group (54% vs 18%; P = 0.0001) for patients who met criteria. Conclusion A pharmacist-led aspirin deprescribing protocol within a primary care setting significantly decreased the number of aspirin prescriptions compared with PCP education only.

Narrative Literature Review Guided Approach of Inhaled Corticosteroid de-escalation in Chronic Obstructive Pulmonary Disease.

Objective: To review the 2020 Global Initiative for Chronic Obstructive Lung Disease (GOLD) report recommendations and create an algorithm to assist clinicians in determining which chronic obstructive pulmonary disease (COPD) patients qualify for inhaled corticosteroid (ICS) de-escalation. Data Sources: A literature search of MEDLINE/PubMed from 2002 to August 2021 was conducted using the search terms inhaled corticosteroids, chronic obstructive pulmonary disease, and de-escalation and review of the reference lists of identified articles for pertinent citations. Study Selection and Data Extraction: Relevant studies and articles were included if they focused on the utilization of ICS in COPD. Data Synthesis: The 2020 GOLD report only recommends triple therapy with ICS, long acting beta agonists, and long acting muscarinic antagonists for patients with frequent exacerbations, frequent hospitalizations, or elevated blood eosinophil counts. Despite this clear framework, patients are prescribed ICS without these characteristics. Available evidence suggests that these patients can be de-escalated from ICS therapy without concern for worsening lung function or exacerbations. Relevance to Patient Care and Clinical Practice: Patients with COPD may be experiencing more risk than benefit on ICS therapy. Clinicians should be knowledgeable on how to evaluate patient therapy for appropriateness and know how to safely deprescribe ICS given their limited efficacy in many COPD patients. Conclusion: There remains no specific guidance on how to de-escalate patients off an ICS when the therapy is not indicated. Use of clinical evidence with stepwise algorithms can be models to approach de-escalation of ICS in patients with COPD.

Development and Validation of Quality Measures for Testosterone Prescribing.

Context: Accurate measures to assess appropriateness of testosterone prescribing are needed to improve prescribing practices. Objective: This work aimed to develop and validate quality measures around the initiation and monitoring of testosterone prescribing. Methods: This retrospective cohort study comprised a national cohort of male patients receiving care in the Veterans Health Administration who initiated testosterone during January or February 2020. Using laboratory data and diagnostic codes, we developed 9 initiation and 7 monitoring measures. These were based on the current Endocrine Society guidelines supplemented by expert opinion and prior work. We chose measures that could be operationalized using national VA electronic health record (EHR) data. We assessed criterion validity for these 16 measures by manual review of 142 charts. Main outcome measures included positive and negative predictive values (PPVs, NPVs), overall accuracy (OA), and Matthews Correlation Coefficients (MCCs). Results: We found high PPVs (>78%), NPVs (>98%), OA (≥94%), and MCCs (>0.85) for the 10 measures based on laboratory data (5 initiation and 5 monitoring). For the 6 measures relying on diagnostic codes, we similarly found high NPVs (100%) and OAs (≥98%). However, PPVs for measures of acute conditions occurring before testosterone initiation (ie, acute myocardial infarction or stroke) or new conditions occurring after initiation (ie, prostate or breast cancer) PPVs were much lower (0% to 50%) due to few or no cases. Conclusion: We developed several valid EHR-based quality measures for assessing testosterone-prescribing practices. Deployment of these measures in health care systems can facilitate identification of quality gaps in testosterone-prescribing and improve care of men with hypogonadism.

Evaluation of a statewide pharmacy student writing club program: Opportunities to enhance professional writing skills.

INTRODUCTION: Skills gained by writing a scholarly manuscript coincide with graduation expectations prior to matriculation into practice. A partnership between The Journal of the Pharmacy Society of Wisconsin and four affiliated pharmacy schools developed student writing clubs (SWC) to fill this need. The objectives of this project were to explore the structure of SWCs and evaluate the experiences of participants. METHODS: Two investigator-designed, voluntary, anonymous surveys were distributed to each school. A survey for pharmacy students assessed motivations for participating within a SWC, impact on skills, and suggestions for improvement. The second survey to the SWC faculty advisors explored programmatic structure. RESULTS: Of forty student respondents, most SWC participants felt comfortable with each step of the writing process. Participants were motivated by manuscript publication opportunity (88%), improvement of writing skills (80%), and the addition to their curriculum vitae (60%). Students suggested process improvements including better communication on deadlines, more connections to writing resources, and developing writing workshops for guidance on professional writing. Barriers to participation included unclear expectations (60%) and not feeling prepared or skilled enough (53%). Most importantly, both students and faculty perceived the SWC at each program as a skill-building extracurricular activity that brings value to student pharmacist development. CONCLUSIONS: Manuscript preparation and publication within a structured environment, such as a SWC, is a valuable skill-building opportunity. Creation of a centralized writing workshop will provide guidance for participants throughout the manuscript process.

Implementation of a Targeted Inhaled Corticosteroid De-Escalation Process in Patients with Chronic Obstructive Pulmonary Disease in the Primary Care Setting.

Purpose: To evaluate the feasibility and success of a pharmacist-led, targeted inhaled corticosteroid (ICS) de-escalation process in patients with chronic obstructive pulmonary disease (COPD) where the risks of ICS therapy outweigh the potential benefits. Methods: A population health data management tool was leveraged to identify patients who may qualify for ICS de-escalation. Primary care pharmacists clinically reviewed and subsequently contacted patients who were determined to be appropriate candidates. After discussion on the risks and benefits of ICS therapy, a stepwise algorithm was utilized to assist with ICS de-escalation and optimization of bronchodilator therapy. Outcomes analyzed include the proportion of patients for whom ICS was de-escalated, patient acceptability of the intervention, time taken to complete the intervention, barriers to implementation, and the number of additional interventions made by pharmacists. Results: Of the 126 patients originally identified as potential candidates, 58 (46.0%) were deemed appropriate to proceed with ICS de-escalation and successfully contacted by a pharmacist. Of these patients, 49 (84.5%) were agreeable and ultimately 42 were successfully de-escalated with 37 patients maintained off ICS. The average time required for an encounter was 15.8 minutes. Conclusion: There is utility in a pharmacist-driven, targeted ICS de-escalation process to facilitate meeting guideline-directed medication therapy goals in patients with COPD, granted the availability of efficient tools to assist in identifying patients that qualify. Such a targeted approach increases pharmacist involvement in medication management of COPD and can expand the primary care pharmacy practice.

Aerobic exercise elicits clinical adaptations in myotonic dystrophy type 1 patients independently of pathophysiological changes.

BackgroundMyotonic dystrophy type 1 (DM1) is a complex life-limiting neuromuscular disorder characterized by severe skeletal muscle atrophy, weakness, and cardiorespiratory defects. Exercised DM1 mice exhibit numerous physiological benefits that are underpinned by reduced CUG foci and improved alternative splicing. However, the efficacy of physical activity in patients is unknown.MethodsEleven genetically diagnosed DM1 patients were recruited to examine the extent to which 12 weeks of cycling can recuperate clinical and physiological metrics. Furthermore, we studied the underlying molecular mechanisms through which exercise elicits benefits in skeletal muscle of DM1 patients.RESULTSDM1 was associated with impaired muscle function, fitness, and lung capacity. Cycling evoked several clinical, physical, and metabolic advantages in DM1 patients. We highlight that exercise-induced molecular and cellular alterations in patients do not conform with previously published data in murine models and propose a significant role of mitochondrial function in DM1 pathology. Finally, we discovered a subset of small nucleolar RNAs (snoRNAs) that correlated to indicators of disease severity.ConclusionWith no available cures, our data support the efficacy of exercise as a primary intervention to partially mitigate the clinical progression of DM1. Additionally, we provide evidence for the involvement of snoRNAs and other noncoding RNAs in DM1 pathophysiology.Trial registrationThis trial was approved by the HiREB committee (no. 7901) and registered under ClinicalTrials.gov (NCT04187482).FundingNeil and Leanne Petroff.

Implementation of a Pilot Pharmacist Testosterone Therapy Management Service.

BACKGROUND: Recent literature findings suggest that opportunities exist to optimize testosterone replacement therapy management. OBJECTIVE: To evaluate the impact of a pilot clinical pharmacist testosterone therapy management service in a Veterans Affairs primary care setting. METHODS: A 6-month, single-clinic, prospective cohort quality improvement project included male patients with an active prescription for testosterone. Patients were excluded if they switched primary care providers or were managed by a specialty clinic. After diagnosis, primary care providers had the option of referring patients for clinical pharmacist testosterone replacement therapy management. The project investigated the impact of pharmacist management on adherence to guideline-defined baseline and therapeutic monitoring, prior authorization workload, time saved by primary care providers, and clinical pharmacist interventions. RESULTS: Sixty patients split between pharmacist management (N = 35) and nonpharmacist management (N = 25) cohorts. Monitoring of baseline parameters was significantly improved with clinical pharmacist management (54% vs 20%, P = 0.0006). Improved baseline monitoring decreased prior authorization team workload as requests were approved on the first submission at a higher rate (100% vs 75.4%, P = 0.06). Pharmacist management increased therapeutic monitoring for assessing symptom improvement (96% vs 26%, P < 0.001), monitoring of testosterone levels (96% vs 61%, P = 0.003), and safety monitoring with complete blood counts (100% vs 83%, P = 0.04). A total of 42 pharmacist-patient encounters saved over 600 minutes of primary care provider time. CONCLUSION: Clinical pharmacist involvement enhances therapeutic monitoring for male hypogonadism leaving room for expansion of clinical pharmacy services within testosterone replacement therapy management.

A novel wireless implant for central venous pressure measurement: First animal experience.

Background/Objective: Central venous pressure (CVP) serves as a surrogate for right atrial pressure, and thus could potentially predict a wider range of heart failure conditions. The purpose of this work is to assess CVP, through an implantable sensor incorporated with a novel anchor design, in the inferior and superior vena cava of an animal model. Methods: Two animals (Dorset sheep) were implanted with sensors at 3 different locations: inferior vena cava (IVC), superior vena cava (SVC), and pulmonary artery (PA). Two sensors with distinct anchor designs considering anatomical requirements were used. A standard PA sensor (trade name Cordella) was deployed in the PA and SVC, whereas a sensor with a modified cylindrical anchor with various struts was designed to reside in the IVC. Each implant was calibrated against a Millar catheter reference sensor. The ability of the central venous sensors to detect changes in pressure was evaluated by modifying the fluid volume of the animal. Results: The sensors implanted in both sheep were successful, which provided an opportunity to understand the relationship between PA and CVP via simultaneous readings. The mapping and implantation in the IVC took less than 15 minutes. Multiple readings were taken at each implant location using a hand-held reader device under various conditions. CVP recorded in the IVC (6.49 mm Hg) and SVC (6.14 mm Hg) were nearly the same. PA pressure (13-14 mm Hg) measured was higher than CVP, as expected. The SVC waveforms showed clear beats and respiration. Respiration could be seen in the IVC waveforms, but not all beats were easily distinguishable. Both SVC and IVC readings showed increases in pressure (3.7 and 2.7 mm Hg for SVC and IVC, respectively) after fluid overload was induced via extra saline administration. Conclusion: In this work, the feasibility of measuring CVP noninvasively was demonstrated. The established ability of wireless PA pressure sensors to enable prevention of decompensation events weeks ahead can now be explored using central venous versions of such sensors.

Population Health Management during Student Pharmacist Introductory Experiential Education to Expand Clinical Pharmacist Impact.

OBJECTIVE: To evaluate the impact of incorporating pre-advanced pharmacy practice experience (pre-APPE) student pharmacists into three different population health management (PHM) projects. METHODS: The prospective quality improvement projects incorporated three third-year student pharmacists who developed and conducted individual PHM projects over the course of three to seven months. The projects included hypoglycemia screening, hepatitis C virus and human immunodeficiency virus screening, and statin use evaluations for atherosclerotic cardiovascular disease risk reduction. Under the guidance of a clinical pharmacist, students developed project materials, conducted patient chart reviews, and contacted patients to make interventions such as recommendations for therapy, ambulatory patient monitoring, patient education, and arranging provider follow-up. Student impact was evaluated through the number of patients screened, the number of eligible patients contacted, and the total number of interventions or recommendations made. Student time spent was tracked throughout the projects. RESULTS: Out of 244 patients screened, 198 patients met inclusion criteria and 162 patients were contacted or assessed by a student pharmacist. Students made a total of 319 interventions, including patient education (132), patient monitoring (132), pharmacotherapy recommendations (28), and arranging follow-up (27). On average students screened 33 patients per month, and, per patient, required 8.6 minutes for eligibility assessment and approximately 6 minutes for telephone interviews. CONCLUSION: This report demonstrates that pre-APPE student pharmacists are well-equipped to design and implement PHM projects. Utilization of student pharmacists in similar PHM programs can expand the pharmacist's impact on patient care in the ambulatory care setting.

Veno-arterial Loop Aiding Mitral Valve Crossing for Balloon Mitral Valvuloplasty in a Patient With a Huge Left Atrium.

Veno-arterial loop is a feasible and safe technique to facilitate mitral valve crossing for balloon mitral valvuloplasty in mitral stenosis patients.

Impact of fractional flow reserve on decision-making in daily clinical practice: A single center experience in Egypt.

BACKGROUND: Fractional flow reserve (FFR) is the reference standard for the assessment of the functional significance of coronary artery stenoses, but remains underutilized. Our aims were to study whether FFR changed the decision for treatment of intermediate coronary lesions and to assess the clinical outcome in the deferred and intervention groups. METHODS: In this retrospective study, coronary angiograms of patients with moderately stenotic lesions (40-70%) for which FFR was performed were re-analyzed by three experienced interventional cardiologists (blinded to FFR results) to determine its angiographic significance and whether to defer or perform an intervention. RESULTS: We revised 156 equivocal lesions of 151 patients. The clinical presentation were stable angina (65.6%) and acute coronary syndrome in (34.4%). All reviewers had concordant agreement to do PCI in 59 (37.8%) lesions based on angiographic assessment. Interestingly 23 (39%) of these lesions were functionally non-significant by FFR. The reviewers agreed to defer 97 (62.2%) lesions, however, 32 (33%) of these lesions were functionally significant by FFR and necessitated PCI. MACE were similar in both groups (1.5% vs 2.4%, p = 1.0). CONCLUSION: Mismatches between visually- and FFR- estimated significance of intermediate coronary stenosis are frequently encountered across a wide spectrum of clinical presentations. FFR leads to a change in decision for coronary intervention. The clinical and cost implications of such changes-in areas with limited resources- needs further evaluation.

Integration and assessment of the situation-background-assessment-recommendation framework into a pharmacotherapy skills laboratory for interprofessional communication and documentation.

BACKGROUND AND PURPOSE: The situation-background-assessment-recommendation (SBAR) framework is a commonly used method to structure verbal communication in the nursing and medicine disciplines and increases the effectiveness of interprofessional communication. The purpose of this manuscript is to describe how the SBAR framework is integrated into a pharmacotherapy skills laboratory for interprofessional communication and to report on student agreement of perceived realism, preparedness, and fairness of assessment relating to simulated SBAR activities. EDUCATIONAL ACTIVITY AND SETTING: Simulated, authentic interactions with healthcare providers were incorporated into a pharmacotherapy skills laboratory using the SBAR framework. Activities culminated with a performance-based assessment (PBA) exam which included verbal and written SBAR stations. Students completed a PBA exit survey reporting level of agreement with perceived realism, preparedness, and fairness of assessment related to the exam and answered open-ended questions reporting what they most and least liked. FINDINGS: After completion of the PBA exam, students reported they agreed or strongly agreed (78%) the PBA was realistic to practice. Students reported increased agreement they were prepared to verbally communicate recommendations compared to document recommendations in the written SBAR framework (64% and 52% agreed or strongly agreed, respectively). Thematic content analysis revealed students preferred to document in the SBAR format and felt it was more realistic than the subjective-objective-assessment-plan (SOAP) note format. DISCUSSION AND SUMMARY: The SBAR framework is relevant for pharmacist verbal communication and written documentation. Incorporation of the SBAR framework into a skills laboratory appears to prepare students for a PBA that was perceived as both realistic and fair.

A multicenter, prospective, randomized, single-blind, controlled clinical trial comparing VASER-assisted Lipoplasty and suction-assisted Lipoplasty.

BACKGROUND: No scientific comparative study has demonstrated any statistically significant clinical improvement attributable to a new lipoplasty technology relative to traditional suction-assisted lipoplasty. This prospective study used a contralateral study design to evaluate postoperative differences between vibration amplification of sound energy at resonance (VASER)-assisted lipoplasty and suction-assisted lipoplasty. METHODS: Twenty female patients between the ages of 20 and 48 years received contralateral treatment with suction-assisted lipoplasty and VASER-assisted lipoplasty in one or more anatomical regions for a total of 33 regions. Patients received suction-assisted lipoplasty on one side of the body and VASER-assisted lipoplasty on the contralateral side. Patients were blinded to technology application. Aspirate was analyzed for blood content, and skin retraction was analyzed by measuring changes in ultraviolet light tattoos. RESULTS: Regarding skin retraction, the VASER-assisted lipoplasty-treated side resulted in a statistically significant improvement in skin retraction of 53 percent relative to suction-assisted lipoplasty (17 percent per liter versus 11 percent per liter, p = 0.003) with 33 paired sites using a two-tailed t test. Regarding blood loss, VASER-assisted lipoplasty treatment resulted in a statistically significant reduction in blood loss of 26 percent (11.2 versus 14.0 cc blood/100 cc) relative to the suction-assisted lipoplasty side (p = 0.019 with n = 20 using a two-tailed t test). Subjective measures (i.e., pain, swelling, appearance, and patient and physician preference) showed no statistical difference between the two methods at the 6-month evaluation. CONCLUSIONS: The VASER-assisted lipoplasty method demonstrated improved skin retraction and reduction in blood loss compared with suction-assisted lipoplasty. This is the first study to demonstrate statistically significant and clinically relevant improvements in a new lipoplasty technology relative to suction-assisted lipoplasty.
