(Press-News.org) Cleveland: Only 42 percent of the deaths occurring within 30 days of percutaneous coronary interventions (PCI) were attributable to complications from the procedure, according to a Cleveland Clinic study published online in the Journal of the American College of Cardiology. The research suggests alternative outcome reporting mechanisms for 30-day mortality for PCI should be considered before mandatory reporting regulations are put into place.
PCI is a non-surgical procedure in which balloons and/or stents are used to open blocked or narrowed arteries, which are typically accessed via a catheter placed in an artery in the groin area.
According to the researchers, public reporting of outcomes after PCI, and in particular 30-day mortality, is likely to be mandated by the federal government in the future and is already required in several states. The outcomes reporting would help patients make better informed decisions about their medical care and could form the basis for determining reimbursement amounts from Medicare and Medicaid. Additionally, the data would likely impact physician and hospital reputation, according to the study.
The researchers, led by Mehdi H. Shishehbor, D.O., M.P.H., Ph.D., Director of Endovascular Services in the Sydell and Arnold Miller Family Heart & Vascular Institute at Cleveland Clinic, caution, however, that mandatory reporting also leads to risk avoidance, or physicians turning down the most risky patients – often those who would most benefit from a procedure – out of fear that the patient may die. Prior research has already shown that risk avoidance can occur when outcomes reporting is made mandatory.
The mortality rate for PCI is typically ascertained from death certificates and all cardiac deaths are reported in the 30-day mortality rate. In their study, Dr. Shishehbor and his colleagues examined the records of the 4,078 PCI procedures performed at a single tertiary care center between January 2009 and April 2011. There were 81 deaths occurring within 30 days of the procedure, and of these, 58 percent were cardiac deaths. However, when the researchers conducted a detailed chart review using established and accepted guidelines, they found that only 42 percent of the 30-day deaths were attributable to PCI-related complications, and they measured this in the most conservative manner, according to Dr. Shishehbor. Further, they found that death certificates were only 58 percent accurate for classifying cardiac versus non-cardiac death.
"Outcomes reporting is a vital component of our shift toward accountable care and will be extremely valuable to patients and physicians," said Dr. Shishehbor. "But we must ensure that we are reporting the right outcomes. If we attribute mortality incorrectly to PCI complications, this may lead to risk avoidance, meaning the sickest patients who would benefit the most from interventions – those presenting with heart attack and cardiac arrest – may not get the care they need."
The researchers suggest that outcomes reporting for PCI should be classified into PCI- and non-PCI-related deaths to best reflect quality and operator performance while holding hospitals and physicians accountable for the care they provide.
"These results highlight the limitations of 30-day mortality reporting when death certificates are used and emphasize the need for identifying PCI-related deaths rather than cardiac deaths alone," the researchers write. They say it is "important to classify causes of death into categories which truly reflect a physician and an institution's competence and act as an indicator of performance."

Exposing skin to sunlight may help to reduce blood pressure, cut the risk of heart attack and stroke – and even prolong life, a study suggests.
Researchers have shown that when our skin is exposed to the sun's rays, a compound is released in our blood vessels that helps lower blood pressure.
The findings suggest that exposure to sunlight improves health overall, because the benefits of reducing blood pressure far outweigh the risk of developing skin cancer.
The study has been carried out by the University of Edinburgh.

Women with unintended pregnancy are four times more likely to suffer from postpartum depression at twelve months postpartum, suggests a new study published today (8 May) in BJOG: An International Journal of Obstetrics and Gynaecology.
The study, conducted at the University of North Carolina prenatal clinics questioned participants about pregnancy intention at 15-19 weeks gestational age, and women were classified as having an intended, mistimed or unwanted pregnancy. There were 433 women (64%) with an intended pregnancy, 207 (30%) with a mistimed pregnancy and 40 (6%) ...
An analysis by researchers at the Institute for Immigration Research (IIR) at George Mason University shows that the Boston Marathon bombings had little effect on conversations on social media regarding immigration reform.
Using two different data mining applications, the researchers collected more than 750,000 tweets containing the word "immigration" beginning in February 2013.
"The Boston Marathon bombings on April 15, 2013 provided an unexpected opportunity to examine how this event has affected the immigration reform debate," says Jim Witte, director of the IIR. ...
In 2015, NASA, for the first time, will fly a space mission utilizing a radically different propellant—one which has reduced toxicity and is environmentally benign. This energetic ionic liquid, or EIL, is quite different from the historically employed hydrazine-based propellant, which was first used as a rocket fuel during World War II for the Messerschmitt Me 163B (the first rocket-powered fighter plane).
Within the U.S. space program, hydrazine was used on the 1970s Viking Mars program, and more recently in the Phoenix lander and Curiosity rover Mars missions, as ...
