How the CMS Cardiac Bundle Could Affect Your Hospital

Posted by Roger DeLong, CP, PE, MBA on Sep 28, 2016 6:30:00 AM

In late July, the Centers for Medicare and Medicaid Services (CMS) proposed a bundled payment program for cardiac procedures involving heart attacks and bypass surgeries.

This is part of the agency’s initiative to shift payment from quantity to quality incentives, which means hospitals will be accountable for the quality of care a patient received during their stay and for 90 days after their discharge.

Hospitals will be paid a fixed price for each round of care they provide. If a hospital hits higher quality targets while providing that care, it will be qualify for a higher payment.

Here is how the proposed CMS cardiac bundle could affect your hospital.

How Surgeon Specialization Impacts Patient Outcomes

Posted by Roger DeLong, CP, PE, MBA on Sep 19, 2016 7:00:00 AM

The phrase “practice makes perfect” has never been more true than in surgery. Research shows that better outcomes are associated with an increased procedure volume. While practicing and completing procedures can affect patient outcomes, the British Medical Journal (BMJ) has found that specializing in a specific procedure may be just as important as the number of times you perform it.

How Design Thinking Can Improve Patient Experience

Posted by Roger DeLong, CP, PE, MBA on Aug 8, 2016 6:30:00 AM

An electronic mannequin is splayed on a stretcher in a fictional emergency department, shouting in pain. Nearby, an actor portraying that mannequin’s brother is frantic with worry. This isn’t a scene from a play. Rather, it’s a scene playing out in many top hospitals—an exercise in design thinking.

Exercises in design thinking put actual doctors and nurses at the bedside of fictitious patients where they interact with fictitious family members, all in an effort to improve patient experience.

Do You Really Know Your Pump Flow?

Posted by Roger DeLong, CP, PE, MBA on Jul 13, 2016 6:30:00 AM

Adequately delivered blood flow is necessary for effective hemodialysis, which according to a 2008 national Japanese survey, was on average 197 ± 31 ml/min. With this in mind, a group of Japanese clinicians sought to find the discrepancies between actual delivered flow and the pump flow reported by the dialysis machine.

The Evolving Role of the Cardiac Perfusionist: 3 Trends to Watch

Posted by Roger DeLong, CP, PE, MBA on Jun 8, 2016 6:30:00 AM

As a perfusionist, you love what you do—you’re making a positive impact on people’s lives. For this very clinical profession that has been consigned to the OR, you might be surprised to learn that technology advancements and changes in procedures are allowing perfusionists to leave the OR and make their way to patients’ bedsides.

To get more insight into what’s on the horizon for cardiac perfusion, we spoke to an expert. Here are a few of the trends to watch if you’re a cardiac perfusionist.

How a Leading Texas Hospital Optimizes Venous Drainage

Posted by Roger DeLong, CP, PE, MBA on Jun 3, 2016 6:30:00 AM

Using smaller cannulas for minimally invasive surgery or aggressive cardiopulmonary bypass circuitry miniaturization have increased the need to augment venous drainage to achieve adequate flow rates. This is achieved through vacuum-assisted venous drainage (VAVD) which has been associated with a number of side effects, including:

Surgeons Measure Blood Flow in Newborns with Cardiac Abnormalities

Posted by Roger DeLong, CP, PE, MBA on May 20, 2016 7:00:00 AM

The surgical challenges to correct the cardiac abnormalities in children born with only a single ventricle are enormous and fraught with pitfalls.

Although overall outcomes of the three-staged surgical repair of patients with a functional single ventricle have improved, a high mortality rate still persists after stage I repair, mainly due to “in- parallel” circulation. Stage II repair involves creation of a bidirectional cavopulmonary shunt or BCPS to create an “in- series” circulation to correct this problem.

Evaluating Gastroepiploic Arterial Grafts for CABG

Posted by Roger DeLong, CP, PE, MBA on May 18, 2016 6:30:00 AM

Surgeons at the University of Sapporo Japan analyzed the relationship between intraoperative transit-time flow values and post-op angiographic results of gastroepiploic arterial grafts to the right coronary artery to determine whether the flow values are reliable indicators of early graft patency in gastroepiploic to right coronary artery grafts.

Their study pool included 169 patients who underwent off-pump CABG with GEA-RCA bypass grafts. Eighty-three grafts were anastomosed and flows were measured. An angiogram was taken one week after surgery and the anastomosis of each graft was graded using FitzGibbon grading (Study 1) and graft-flow grading (Study 2).

Flow Measurements Help Predict Outcomes of Kids’ Pulmonary Artery Banding

Posted by Roger DeLong, CP, PE, MBA on May 16, 2016 7:00:00 AM

Pulmonary artery banding (PAB) has been the standard treatment for patients with high pulmonary blood flow who are awaiting subsequent surgery. The band is designed to provide adequate systemic flow to the body by restricting pulmonary flow. This allows the patient to grow and therefore become a better candidate for follow-up surgery.

Transit-time Flow Predicts Outcomes in CABG Patients: 1,000 Consecutive Arterial Grafts

Posted by Roger DeLong, CP, PE, MBA on May 11, 2016 7:00:00 AM

female-doctor-evaluating-study.jpgClinicians at the University of Calgary, Alberta, Canada sought to evaluate transit-time flow (TTF) as a tool to detect technical errors in arterial bypass grafts intraoperatively and predict outcomes. They measured flow in 336 consecutive patients who had an average of 3.02 grafts each. Ninety-nine percent of these bypass grafts were arterial. Three parameters: pulsatility index (PI), flow (cc/min) and diastolic filling (DF) were measured in 990 of the total 1,000 grafts.
