We know that misdiagnosis occurs in family practice offices in Illinois, but before this year there were no comprehensive studies done to determine how often misdiagnosis occurs in a typical family practice in the United States. Recently an article was published in JAMA Internal Medicine revealing that in 190 cases in a family practice setting, a total of 68 unique diagnoses were missed.
In the study, researchers reviewed medical records of 190 occasions of diagnostic error. These were errors that happened between October 1, 2006-September 30, 2007. They were detected in two settings. The first setting was a large urban Veteran Affairs facility with 35 primary care providers. The second setting was a large private health care system with thirty-four family medicine primary care providers. The goal of the study was to determine what potential contributory factors can lead to misdiagnosis.
Researchers found that pneumonia, decompensated congestive heart failure, acute renal failure, cancer, and urinary tract infections were the most commonly missed diagnoses. Just under 79% of the misdiagnoses were related to “process breakdowns” in the encounter between patient and practitioner in the clinical setting, meaning there were many communications breakdowns. In 80% of the missed diagnoses, the doctors involved did not consider all possibilities and prioritize them appropriately, thereby missing the correct diagnosis.
