Nadir hematocrit on bypass and rates of acute kidney injury: does sex matter?
Recent literature has suggested that women, although more often exposed to lower nadir hematocrit (Hct), have a lower risk of postoperative renal dysfunction. The researchers assessed whether this relationship held across a large multicenter registry. They found that lower nadir Hct was associated with an increased risk of AKI, and the effect appears to be stronger among men than women.

Locating errors through networked surveillance: A multimethod approach to peer assessment, hazard identification, and prioritization of patient safety efforts in cardiac surgery.
The objectives of the study were to develop a scientifically sound and feasible peer-to-peer assessment model that allows health-care organizations to evaluate patient safety in cardiovascular operating rooms and to establish safety priorities for improvement. It identified 6 top priority hazard themes: safety culture, teamwork and communication, infection prevention, transitions of care, failure to adhere to practices or policies, and operating room layout and equipment.

Red blood cell transfusions impact pneumonia rates after coronary artery bypass grafting.
This study describes the relationship between red blood cell (RBC) transfusion and postoperative pneumonia after CABG. It found a significant volume dependent association between an increasing number of RBCs and the odds of pneumonia, which persisted after risk adjustment. It included a total of 16,182 consecutive patients who underwent isolated CABG between 2011 and 2013 at 1 of 33 hospitals in the state of Michigan.

Policies allowing family presence during resuscitation and patterns of care during in-hospital cardiac arrest.
A growing number of hospitals have begun to implement policies allowing for family presence during resuscitation (FPDR). However, the overall safety of these policies and their effect on resuscitation care is unknown. This study suggests that hospitals with an FPDR policy generally have no statistically significant differences in outcomes and processes of care as hospitals without this policy.

Statin use after acute myocardial infarction by patient complexity: are the rates right?
The researchers assessed the benefits and risks associated with higher rates of statin use after AMI by baseline patient complexity. Their results provide strong evidence that providers were attempting to individualize statin prescribing to patients after AMI. Statin users after AMI were less complex and had higher rates of prior statin use.

Center-level variation in infection rates after coronary artery bypass grafting.
This study was undertaken to compare observed and expected rates of healthcare-acquired infections (HAIs) across all 33 institutions performing isolated CABG surgery in the state of Michigan. Although predicted risk of HAI differed in absolute terms by 2.8 percent across centers, The study found that observed rates varied by 18.2 percent. Differences in observed rates of infections could not be fully explained by patient case mix.

Approval of high-risk medical devices in the US: implications for clinical cardiology.
The authors review the premarket approval (PMA) process to approve high-risk cardiovascular devices, as well as the five different types of PMA supplements used to approve alterations to device design. They summarize the types of data required to approve new high-risk cardiovascular devices and discuss implications of the PMA process for clinicians and patients.
