Most Surgical Patients Only Use About 25% Of Their Prescribed Opioids

Response: This study examined how much opioid patients use after surgery, and looked at factors that might predispose some patients to use more or less.

Patient opioid use after surgery is an interesting question that’s gained a lot of attention recently, because it’s different from other uses for opioids. If you have chronic pain, you’re probably going to use all of your prescription. But if you have surgery, you may not take all of your pills, and this leaves people with leftover pills that can be dangerous later.

From this study, we found that patients only use, on average, about quarter of their prescription, meaning that a lot of them are left with leftover pills. Moreover, we found that the biggest determinant of how much they used wasn’t how much pain they reported, or any other factor—it was how big their original prescription was.

What this means is that opioid use after surgery isn’t just determined by pain, but also by what surgeons prescribe. It’s important to keep this in mind as we try to reduce unnecessary opioid prescribing after surgical procedures.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We performed this study because of concerns about the potential association between fluoroquinolones and aortic aneurysms and dissection raised in two large clinical studies. This concern was noted by the US Food and Drug Administration in May 2016, but the evidence was not deemed sufficient to warrant a warning. Hence, there was a clear need for additional studies to evaluate the problem. Our study was designed to determine whether there is biological evidence that ciprofloxacin—the most commonly prescribed fluoroquinolone—exacerbates aortic disease in a well-established mouse model. The model uses high-fat diet and angiotensin II infusion to stress the aorta and cause aneurysm and dissection. Using this model, we compared mice that received ciprofloxacin to control mice that received only vehicle, and we found that mice that received ciprofloxacin had significant increases in the incidence of aortic dilatation, severe aortic aneurysm and dissection, and aortic rupture and premature death. Importantly, these findings were consistent in male and female mice. Further, we investigated the potential underlying mechanisms and found that the aortas from mice that received ciprofloxacin had decreased levels of lysyl oxidase, increased levels of matrix metalloproteinases, and increased levels of apoptosis and necroptosis.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Although meniscal surgeries are among the most frequently performed surgical procedures in orthopedic surgery, until just recently there were hardly any randomized trials proving its superiority over conservative treatment.

In this randomized clinical trial, including 321 patients with non-obstructive (e.g. no locking of the knee joint) meniscal tears, we found physical therapy non-inferior to arthroscopic partial meniscectomy.

MedicalResearch.com: What is the background for this study?

Response: Firearm-related mortality is a public health issue. However, in the US, due in part to lack of funding, there is not enough research to inform the debate about firearms.

The question our group sought to answer was to understand if the presence of a semi-automatic weapon increased the number of victims killed or hurt during an active shooter incident. We chose to focus on these incidents given the availability of an FBI database detailing these active shooter incidents based on a strict definition and the similarities between such incidents that make a comparison valid.
