Objective: This study aimed to conduct a comprehensive Gap Analysis on quality parameters in the Emergency Departments of NABH-accredited hospitals in the districts of Dehradun and Haridwar. The primary objective was to assess the extent of compliance with NABH standards in Emergency Departments and identify areas for improvement in quality of care and patient safety. Methods: A cross-sectional design was employed to gather data from Emergency Departments in NABH-accredited hospitals from 1st September 2022 to 30th March 2023. Purposive sampling was used to select participating hospitals from both urban and rural settings. Healthcare professionals working in these Emergency Departments were included as participants. Primary data was collected through structured questionnaires and direct observations, while secondary data was obtained from hospital records and administrative sources. Descriptive statistics were used to analyze the data, presenting the results as frequencies and percentages. Results: A total of 100 NABH-accredited hospitals (where three private medical college & about 10 multispecialty Hospitals) participated in the study. The Gap Analysis revealed variations in the implementation of quality parameters in the Emergency Departments. While certain aspects, such as immunization of staff (71.43%) and the availability of dedicated ventilators (71.43%), demonstrated strong compliance, other areas, such as awareness of allergy band indications (42.86%) and the absence of a dedicated triaging area (48.57%), exhibited potential gaps.
