Patient Safety & Quality Improvement USMLE Step 1 Practice Question
A 45-year-old woman with a history of hypertension presents to her primary care physician reporting symptoms of headaches and fatigue over the past 3 months. Review of her electronic health record shows progressive elevation of systemic blood pressure readings, with recent measurements documented as 160/95 mmHg compared to her previous baseline of 140/85 mmHg. Her antihypertensive regimen was intensified based on these readings. When the patient checks her blood pressure at home using a validated device, readings are consistently 145/88 mmHg. Further investigation reveals that the clinic's automatic blood pressure cuff had been in use without recalibration for 18 months, and no staff member had verified the device's accuracy against a standard manometer during this period. Which of the following quality improvement concepts best explains this systematic failure in patient care?
