Setting:

The practice took place in a primary care family medicine unit in Turkey in 2026. The setting is a community-based clinic serving a diverse patient population, focusing on early diagnosis and preventive care

Target group:

The target group includes primary care patients undergoing colorectal cancer screening, specifically those who may present with acute symptoms despite having negative screening histories

Description of the innovative practice or project:

A 66-year-old male with hypertension and atherosclerotic heart disease presented with a three-day history of inability to defecate and significant abdominal distension. Despite a recent negative Fecal Immunochemical Test (FIT) and a lack of systemic symptoms in previous check-ups, clinical examination revealed diminished bowel sounds and tenderness in the right lower quadrant. Digital rectal exam showed an empty rectum. This practice highlights the innovative use of "Clinical Courage"—prioritizing bedside red flags over reassuring but false-negative screening algorithms

Evaluation:

Through persistent patient advocacy and risk communication, the physician successfully persuaded the patient, who was initially very reluctant to seek emergency care. An urgent CT scan confirmed a 3 cm malignant obstruction in the ascending colon. Due to this timely intervention, the patient was diagnosed at a stage that allowed for a curative surgical outcome.

Next Steps:

This case will be used as a training model for residents to demonstrate the limitations of FIT screening. We plan to develop a "Clinical Intuition Protocol" to formalize safety-netting for symptomatic patients with negative test histories.

Lessons learned:

Lessons LearnedAlgorithms are not absolute: Negative screening tests (FIT) should not exclude malignancy when acute clinical red flags are present.Communication is key: Persistent physician advocacy is vital when patients resist life-saving referrals.Resilience: Trusting one's clinical skills against "normal" data prevents diagnostic delays and strengthens professional confidence.
