The goal of this study is to learn if the prototype adjustable prone positioning frame is a feasible design for use during neurosurgical procedures which utilize intraoperative magnetic resonance imaging (iMRI). The main questions it aims to answer are: * Is the prototype prone positioning device design feasible for use during neurosurgical procedures which utilize intraoperative MRI? * Does use of the prototype device place the patient at increased risk of complications compared to the standard positioning pads? Researchers will place patients in the prone position on the prototype device during neurosurgical procedures that utilize intraoperative MRI and observe for any problems with the positioning device or complications attributable to the positioning device.

The objective of the study is to evaluate the safety and efficacy of the Adient absorbable filter for the prevention of pulmonary embolism (PE: blood clot in the lungs). PE claims the lives of over 100,000 Americans each year, more than breast cancer, traffic fatalities and HIV combined. Pharmaceutical anticoagulation (blood thinners) that reduce blood clot formation represent the standard of care for treating patients at risk for PE. However, for people who are temporarily unable to use anticoagulants, such as those who have suffered major trauma or those who are scheduled for surgical procedures, inferior vena cava (IVC) filters are used to help protect against PE. These blood filters prevent large blood clots that originate in the deep veins of the legs (deep vein thrombosis (DVT)) from reaching your lungs causing a potentially life-threatening PE. Conventional metal IVC filters have been proven effective at reducing the incidence of PE, however, most require retrieval. If not retrieved within a timely manner (months), they can perforate the IVC, impale nearby organs with their barbed struts, and cause blood clots. In contrast, the Adient absorbable filter traps blood clots similar to conventional metal IVC filters, but following the 8 week protection period, the filter itself breaks down into carbon dioxide and water. Hence no filter retrieval is required and complications are less likely due to the shortened indwell time. Once blood clots are trapped in the absorbable filter, the body's thrombolytic enzymes dissolve the clots within weeks while the filter itself resorbs in 6 to 8 months. The absorbable filter is braided from absorbable suture that has been proven safe over 4 decades. The question being addressed with the randomized controlled trial portion is whether the placement of the absorbable filter in addition to current best practice PE prevention (sequential compression machines, compression stockings, and anticoagulants when indicated) significantly reduces the incidence of clinically significant PE in high risk subjects. The absorbable filter will be indicated for the temporary prevention of PE in patients with transient high risk for venous thromboembolism (DVT and/or PE) with or without venous thromboembolic disease and as an enhancement to pharmaceutical anticoagulation and mechanical prophylaxis.

Socioeconomically disadvantaged populations with multiple chronic conditions have high rates of nonadherence to essential chronic disease medications after hospital discharge. Medication nonadherence after hospital discharge is significantly associated with increased mortality and higher rates of readmissions and costs among these patients. Major patient-reported barriers to essential medication use after hospital discharge among low-income individuals are related to social determinants of health (SDOH) and include: 1) financial barriers , 2) transportation barriers, and 3) system-level barriers. Although, medication therapy management services are important during care transitions, these services have not proven effective in improving medication adherence after hospital discharge, highlighting a critical need for innovative interventions. The Medication Affordability, Accessibility, and Availability in Care Transitions (Med AAAction) Study will test the effectiveness of a pharmacy-led care transitions intervention versus usual care through a pragmatic randomized controlled trial of 388 Medicaid and uninsured hospital in-patients with MCC from three large healthcare systems in Tennessee. The intervention will involve: 1) medications with zero copay, 2) bedside delivery then home delivery of medications, and 3) care coordination provided by certified pharmacy technicians/health coaches to assist with medication access, medication reconciliation, and rapid and ongoing primary care follow-up. We will examine the impact of the intervention during 12 months on 1) medication adherence (primary outcome) and 2) rapid primary care follow-up, 30-day readmissions, hospitalizations and emergency department visits, and costs. We will conduct key informant interviews to understand patient experience with the acre received during and after care transitions. By examining effectiveness of the intervention on outcomes including medication adherence, health care utilization, costs, and patient experience, this study will provide valuable results to health systems, payers, and policymakers to assist in future implementation and sustainability of the intervention for socioeconomically disadvantaged populations.

The purpose of this study is to confirm the safety and efficacy of the ThinkSono Guidance System, a software data collection and communication tool designed to collect ultrasound data to help detect blood clots in veins. The ThinkSono system is CE Mark approved in the European Union and in clinical use in Europe. Usually, when an ultrasound is conducted to diagnose blood clots in veins, a sonographer (trained technologist who conducts ultrasounds) and/or radiologist will conduct the procedure, including a compression ultrasound exam, and the scan may require a bulky cart and ultrasound equipment. The ThinkSono Guidance System is a mobile software application that enables other healthcare professionals such as nurses, non-radiologist physicians including general practitioners, and other allied healthcare professionals to perform the ultrasound at the point of care using guidance from the software app. This is a multi-site non-randomized, double-blinded, prospective cohort pivotal study.

A new algorithm derived from only patient age and components of the complete blood count and basic metabolic panel can identify patients discharged from the hospital who may benefit from a blood thinner (called rivaroxaban) to decrease their risk of blood clots, and for whom the risk of bleeding is minimal. The purpose of this study is to evaluate the use of a pop-up alert, which will be seen by clinicians when a discharging patient has been identified as being someone for whom the risk of blood clots is high, but for whom bleeding risk is estimated to be low. The pop-up alert will be enabled in a sequential fashion for each group of hospitals in 1 month blocks. We will look to see if the pop-up alert changes the number of patients who receive rivaroxaban. We will also measure the outcomes of blood clots and bleeding among all discharging patients.

The researchers hypothesize that existing-prescription notifications directed to pharmacists are more likely to lead to a prescription change than existing-prescription notifications directed to prescribers. Furthermore, the researchers hypothesize that the availability of a pharmacist referral option is associated with a higher rate of prescription changes for initial-prescription alerts that are directed to the prescriber at the time of initial-prescribing errors. Findings from this project will establish a framework for implementing prescriber-pharmacist collaboration for high risk medications, including anticoagulants

Pulmonary embolism (PE) remains a high mortality and morbidity disease state. The investigators have previously shown that use of a Pulmonary Embolism Response Team (PERT) can improve overall readmission, bleeding, and mortality outcomes. Unfortunately, PERT may still be underutilized from a national standpoint and may not be readily available in underserved areas. The use of artificial intelligence (AI) may help streamline and systematically ensure unbiased mechanism for activation of PERT for discussion of patients with siginficant clot burden and hemodynamic abnormalities. AI algorithms have been FDA approved for use of triage of the PE patient. The institutional PERT program will adapt the use of an AI algorithm for activation as routine care; the efficiency of activation will be compared to our retrospective historical comparison for efficiency and appropriateness of activation. The active phase of the study is designed to further differentiate between patients who are considered to be intermediate-high risk category but yet do not clearly qualify for invasive therapy (catheter-directed therapy, systemic thrombolysis, or invasive hemodynamic support). These patients will undergo walking test to further understand noninvasive hemodynamic compromise and undergo 2:1 randomization to early-invasive strategy versus mtranditional medical therapy.

Inflammatory bowel disease (IBD) is a relatively common disease that effects all age groups and carries significant morbidity and mortality. The initial treatment typically involves both short and long term medication, however when this is not enough to adequately control the disease, surgery is often required. The high morbidity and mortality rates are in part due to the increased rates of venous thromboembolism (VTE) such as deep vein thrombosis (DVT) or pulmonary embolism (PE) which have been shown to develop more frequently in IBD patients compared to the general population. Undergoing abdominal surgery has also been shown to independently increase rates of DVT and PE and since the majority of patients with IBD will undergo surgery at least once in their lifetime, the relative increased risk of developing a VTE is very high. The majority of DVT and PE events in the postoperative IBD population will occur after discharge from hospital and therefore carries significant morbidity and mortality risk in a unmonitored setting. Several studies have demonstrated the benefits and safety of twice daily dosing of oral extended VTE prophylaxis agents in orthopedic and cancer postoperative patients following discharge from hospital. There have been no randomized studies which have evaluated the use of extended postoperative VTE prophylaxis in IBD patients. The purpose of this randomized placebo controlled pilot trial will be to evaluate the efficacy and safety of postoperative VTE prophylaxis in IBD patients following abdominal surgery. If this pilot trial demonstrates efficacy in reducing postoperative DVT and PE rates, safety and feasibility, clinicians will be armed with the knowledge to pursue a larger multicenter randomized trial with the intent of reducing overall morbidity and mortality in this high risk population.

While blood clots after major cancer surgery are common and harmful to patients, the medications to decrease blood clot risk are seldom used after patients leave the hospital despite the recommendation of multiple professional medical societies. The reason why these medications are seldom prescribed is not well understood. The main questions this study aims to answer are: * Does surgeon education paired with an electronic medical record based decision support tool improve the guideline concordant prescription of pharmacologic venous thromboembolism after abdominopelvic cancer surgery? * Does dedicated patient education regarding blood clots at the time of hospital discharge after abdominopelvic cancer surgery improve understanding of the risk of venous thromboembolism and adherence to pharmacologic prophylaxis? The investigators will study these questions using a stepped-wedge randomized trial where groups of surgeons will use a tool integrated to the electronic medical record to educate them on the individualized patient risks of blood clots after major cancer surgery and inform them regarding guidelines for preventative medicines. Utilization of the medications before and after using the tool will be compared. Patients will be administered a questionnaire assessing their awareness of blood clots as a risk after cancer surgery. For those prescribed medications to reduce blood clot risk after leaving the hospital, the questionnaire will evaluate whether they took the medications as prescribed. Survey results will be evaluated before and after implementation of education on blood clot risk at the time of hospital discharge.

Frequently Asked Questions

How much do Pulmonary Embolism clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Pulmonary Embolism clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Pulmonary Embolism trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Pulmonary Embolism is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Pulmonary Embolism medical study ?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Pulmonary Embolism clinical trials ?

Most recently, we added Non-Invasive Hemodynamic Monitoring for Pulmonary Embolism, Exercise Training for Pulmonary Embolism and Postpartum Aspirin for Blood Clots to the Power online platform.
