Abstract:
Shared decision-making (SDM) can help patients make good decisions about preventive health interventions such as cancer screening. We illustrate the use of SDM in the case of a 53-year-old man who had a new patient visit with a primary care physician and had never been screened for colorectal cancer (CRC). The patient had recently recovered from a serious COVID-19 infection requiring weeks of mechanical ventilation. When the primary care physician initially offered a screening colonoscopy, the man expressed great reluctance to return to the hospital for the exam. The PCP then offered a stool test, which could be completed at home, but emphasized that if it were positive, a colonoscopy would be required. He agreed to complete the stool test, and unfortunately, it was positive. He then agreed to undergo colonoscopy, which uncovered a large rectal cancer. The carcinoma had invaded the mesorectal fat but there were no metastases. After undergoing neoadjuvant chemotherapy followed by a low anterior resection of the tumor, he has no evidence of recurrence so far. Many clinicians favor colonoscopy for CRC screening, but evidence suggests that patients who are offered more than one reasonable option are more likely to undergo screening. If screening had been delayed in this patient until he was willing to accept a screening colonoscopy, there was the potential the cancer may have been more advanced when diagnosed, with a worse outcome. Shared decision-making was a key approach to understanding the patient's feelings related to this screening decision and making a decision consistent with his preferences.
