In a troubling revelation for healthcare facilities, a recent study coming out of Harvard-affiliated Brigham and Women's Hospital has reported a high rate of diagnostic errors in intensive care units at hospitals nationwide. The Harvard Gazette stated that, the orchestrators of the research at Brigham and the University of California San Francisco discovered that out of a group of 2,428 patients studied, a striking 23 percent had been subject to a diagnostic error.
In an unsettling insight into patient safety the majority of these mishaps were not just academic oversights; they directly harmed the patients involved. In a statement obtained by the Harvard Gazette, Dr. Jeffrey L. Schnipper, the study's senior author, noted, "We found that diagnostic errors can largely be attributed to either errors in testing, or errors in assessing patients, and this knowledge gives us new opportunities to solve these problems." His sentiment was as clear as it was dire: "even a single patient death that might have been prevented with a better diagnostic process is one death too many." This comes as a stark reminder of the precarious position patients are in, when even the most critical units are prone to error.
The research, which was published in JAMA Internal Medicine, is one of the few investigations that attempt to quantify the prevalence and causes of diagnostic errors in hospitals. It was meticulously conducted, with patient cases being examined by two-physician teams trained in error adjudication. The researchers' painstaking work revealed that out of the 550 diagnostic errors identified, 486 led to some kind of harm.
While Schnipper and the team identified that testing and assessment were the usual culprits behind these errors, the study is pushing for systemic changes rather than merely pointing fingers. Schnipper clarified, in unmistakable terms: "Our study does not tell us the overall frequency of diagnostic errors in the hospital, but it does tell us that there’s more we can be doing to prevent these types of errors from occurring." As they look towards solutions, the Brigham team, along with DECODE, the hospital's Diagnostic Centers of Excellence program, is concentrating on decreasing diagnostic mistakes, especially those related to medical imaging and electronic health records.
Future efforts of the researchers are geared towards the implementation of hospital-wide surveillance systems that will hopefully capture diagnostic errors as they happen, allowing for comparisons across institutions and the testing of potential solutions. With such diagnostic errors contributing to a sobering 6.6 percent of hospital deaths in their sample, there is an evident and pressing need for health system reforms that could safeguard patient lives against such preventable faults.
