A cost analysis of colonoscopy using microcosting and time-and-motion techniques

Area of Science:

• Health Economics
• Gastroenterology
• Public Health

Background:

• Colonoscopy cost is key to colorectal cancer screening cost-effectiveness.
• Existing cost estimates vary and use institutional gross-costing methods.

Purpose of the Study:

• To determine the total societal cost of colonoscopy using micro-costing and time-and-motion techniques.
• To include direct healthcare, non-healthcare, and patient time costs.
• To analyze costs from a societal perspective.

Main Methods:

• Prospective cohort study of 276 patients undergoing colonoscopy.
• Utilized micro-costing and time-and-motion techniques.
• Data collected at a Veterans' Affairs Medical Center and a University Hospital.

Main Results:

• Median direct healthcare cost: $379.
• Median patient time cost: $274.
• Median total societal cost: $923, encompassing direct healthcare, non-healthcare, and patient time costs.

Conclusions:

• Micro-costing and time-motion studies provide accurate cost estimates for medical interventions.
• Total societal costs, including patient time, are essential for health policy and cost-effectiveness analyses.
• Societal cost estimates may influence colonoscopy screening rates.
