Comparative Cost Analysis of Ambulance Utilization: Advanced Life Support (ALS) vs Basic Life Support (BLS) at King Abdulaziz Medical City, Riyadh.
Article in ClinicoEconomics and outcomes research : CEOR, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Unit-hour utilization (UHU) is the most common metric for evaluating the productivity of ambulances and crews for ambulance services. Calculating UHU is essential for maximizing profitability and evaluating the number of hours of ambulance utilization during a shift. This has not been examined previously at King Abdulaziz Medical City (KAMC). KAMC is a major tertiary-care medical center in Riyadh, Saudi Arabia, with dedicated ALS (Advanced Life Support) and BLS (Basic Life Support) ambulance units. This study aimed to determine the cost of operating the emergency calls (advanced life support [ALS]) unit and non-emergency calls (basic life support [BLS]) unit and compare the costs of emergency calls (ALS) and non-emergency calls (BLS). The study used a standardized institutional checklist that itemizes expenditures across logistics, equipment, maintenance, salary, pharmacy, and fuel cost components. Methods: This was a retrospective cross-sectional study. Institutional Review Board approval was obtained from King Abdullah International Medical Research Center. The study examined emergency and non-emergency calls for a period of 12 months. This study was based on a checklist assessing various expenditures to calculate the cost of ambulance utilization at KAMC in 2022. Results: The total average ambulance utilization cost per year for ALS was 4,806,245.7 SR, and the average ambulance utilization cost per hour was 548.65 SR; these costs were to operate the ALS crew for 24 hours, seven days a week. Conversely, the total average ambulance utilization cost per year for BLS was 3,934,156.92 SR, and the average ambulance utilization cost per hour was 449.10 SR. The main expenses concerned salaries and overhead costs for ALS and BLS. Conclusion: This study provides insights into the cost of ambulance utilization between ALS and BLS. The higher cost of ALS calls may be attributed to the higher level of training, equipment, and staffing required.
