Some patients develop blood clots despite optimal care, and others are being inadequately treated to prevent clots, according to a study of hospital-acquired venous thromboembolism (VTE) published online July 29 in JAMA Surgery. The researchers argue that financial penalties, such as those levied by the Centers for Medicare & Medicaid Services, unfairly punish hospitals for VTEs that cannot be prevented.
"To reduce preventable harm, policymakers need to re-evaluate how they penalize hospitals and improve the measures they use to assess VTE prevention performance. In addition, clinicians need to ensure that patients receive all prescribed preventive therapies," first author Elliott Haut, MD, PhD, from the Division of Acute Care Surgery at Johns Hopkins University School of Medicine in Baltimore, Maryland, notes in a university news release.
The investigators examined records for the 128 patients who developed VTEs in the Johns Hopkins Hospital between July 2010 and June 2011 and whose cases were flagged by a pay-for-performance initiative. Of those, 36 (28%) were upper-extremity catheter-related DVT, which the researchers judged to be nonpreventable, and were excluded from further analysis.
Of the remaining patients, 45 had DVT only, 43 had a pulmonary embolism only, and four had both.
Of these patients, 43 (47%) received "defect-free" care, which the researchers argue should not be penalized because best care practices were followed.
Among the 49 (53%) patients who received care that was less than ideal, 13 patients were not prescribed risk-appropriate prophylaxis, and 36 missed at least one dose of appropriately prescribed prophylaxis.
The importance of missed doses has been underappreciated, the authors note, and should be the focus of future prevention efforts.
“Our study identifies a need to dramatically reevaluate the VTE outcome and process measures,” the authors write. “Half of VTE events identified in a state-run pay-for-performance program were not truly preventable because patients received best-practice prevention, and there was no real opportunity for improvement.”
