Accurate blood pressure (BP) measurement is essential for detecting, diagnosing, treating, and monitoring hypertensive individuals. This qualitative improvement initiative study is aimed at improving adherence to standardised BP measurement protocols in an urban primary health centre in Delhi, India. This study was conducted using a checklist based on World Health Organisation (WHO) guidelines. Baseline assessment revealed low adherence to standardised procedures. Interventions included crowd management, infrastructure and equipment, standard operating procedures (SOPs) development, and staff training. After two plan-do-study-act (PDSA) cycles conducted within six weeks, the adherence to standardised BP measurement significantly increased from 0.4% (n=1) to 86.2% (n=119). This study highlights the potential for targeted quality improvement in healthcare delivery.
