pics print keygen Waiting Games: Competition for Donor Hearts May Encourage Overtreatment

crackle ps vita app In the U.S., candidates for heart transplantation are prioritized by the intensity of treatment they’ve received, potentially leading some centers to overtreat patients to improve their odds of getting a donor heart.

xdm crack More than one-third of transplant candidates never receive a donor heart, according to William F. Parker, MD, of the University of Chicago, and colleagues who published a Journal of the American College of Cardiology (JACC) article on how the supply–demand gap may be driving competition for organs (2018;71[16]:1715-25).

descargar router keygen para celular samsung chat “Status is determined by treatment intensity, based on the premise that candidates nearer death will require escalation of life-sustaining therapies,” the researchers wrote. “There were expected to be relatively few patients waiting at the highest priority ‘Status 1A,’ as these candidates who are receiving the most intense forms of cardiac life-support therapy should have short life expectancies without heart transplantation. However, the proportion of Status 1A candidates has doubled in the past 10 years and now less than 40 percent of candidates wait at this highest priority designation, decreasing the likelihood that lower priority candidates are allocated a donor heart.”

They included only individuals who did not meet hemodynamic criteria for cardiogenic shock, thus leaving them open to possible overtreatment with high-dose inotropes or an intra-aortic balloon pump (IABP)—two forms of therapy that could bump patients up the waitlist.

Local competition with two or more centers in the same organ procurement organization was associated with 50 percent greater odds of potential overtreatment. In addition, major urban areas such as New York, Los Angeles and Chicago had high rates of potential overtreatment—further supporting the idea that competition is driving the phenomenon.

Compared to candidates in bottom-quartile centers, those in the most aggressive treatment centers received donor hearts more quickly (median 146 days vs. 412 days) and had higher survival rates.

Furthermore, for an individual patient, the risks of a long wait at lower status may outweigh the harms of overtreatment.”

Doing so could ensure candidates who need heart transplants the most are more likely to receive them, as well as reduce unnecessary complications from overtreatment.

application icoyote android cracked A new era of heart transplant allocation is unfolding, according to  Larry A. Allen, MD, MHS, and Prateeti Khazanie, MD, MPH, of the University of Colorado School of Medicine, who wrote a JACC editorial (2018;71[16]:1726-8). In 2018, the United Network for Organ Sharing will begin phasing out the current three-category system (1A, 1B and 2) and implementing a new six-category system (1 to 6). The editorialists say the new system includes “broader geographic sharing of organs across the country for the highest-tier patients, more concrete definitions for [mechanical circulatory support] complications, and objective requirements that patients must meet the American Heart Association hemodynamic criteria for cardiogenic shock to warrant higher listing status.”

Some conditions still weigh more heavily into the classification of transplant candidates than others, which could “further exacerbate disparities in care,” Allen and Khanzani wrote.

However, ... fair play is not always natural.
