HealthDay News — Fewer than half of adults have a follow-up colonoscopy within 6 months following an abnormal stool-based screening test (SBT) for colorectal cancer (CRC), according to a study published online March 25 in JAMA Network Open.
Elizabeth L. Ciemins, PhD, MPH, from the American Medical Group Association in Alexandria, Virginia, and colleagues conducted a retrospective quality improvement study to develop and test a quality performance measure for follow-up colonoscopy within 6 months of an abnormal result of an SBT for CRC. To determine follow-up colonoscopy rates within 6 months in a database study, adults from 38 health care organizations (HCOs) aged 50 to 75 years who completed an initial CRC SBT with an abnormal result were observed.
The researchers found that 47.9% of the 20,581 adults in 38 health systems had a follow-up colonoscopy following an abnormal SBT result for CRC within 6 months. Significant variation was seen between HCOs. Follow-up colonoscopy was received by significantly fewer Black patients (37.1%) and patients with Medicare or Medicaid insurance (49.2 and 39.2%, respectively). A quality performance measure that tracks rates of follow-up within 6 months of an abnormal SBT result was feasible, valid, and reliable; the median reliability statistic was 94.5% between HCOs.
“Use of SBTs may increase overall screening rates, but abnormal results must be followed up with a colonoscopy to diagnose CRC, ideally as soon as possible, but definitely within the six months after an abnormal test result,” the authors write.
