Background:
Laboratory performance benchmarking can be a tool for improving diagnostic efficiency, cost-effectiveness, and patient outcomes. This study evaluates key operational metrics for Indian hospital laboratories by leveraging data from the Asia–Pacific region to establish reference benchmarks.
Materials and Methods:
Data were collected from the Indian Clinical Chemistry Benchmarking survey, conducted between November 2022 and April 2023. Hospital-based laboratories were categorized based on daily sample workload and analyzed for laboratory turnaround time (TAT), test density, and productivity metrics. Comparisons were made against the Asia–Pacific region to identify opportunities for improvement. It is important to note that the findings may be influenced by selection bias, as participation was voluntary and may not fully represent the broader laboratory landscape.
Results:
Workload distribution was comparable; however, the surveyed Indian hospital-based laboratories exhibited lower operational efficiency. The study highlights that laboratory TATs in Indian hospitals can be optimized by 25%–67% to align with benchmark standards observed across the Asia–Pacific region. In comparison with the Asia–Pacific region, the test density in Indian laboratories showed a 15%–22% scope for improvement. High-throughput laboratories (>1000 samples/day) present an opportunity for efficiency enhancement, with a potential 51% improvement in staff productivity. In addition, space utilization can be optimized by 24%–74% across all workload categories.
Conclusion:
Indian laboratory metrics have room for improvement in terms of laboratory TAT, test density, workforce productivity, and space management. Implementing Lean methodologies and adopting standardization of processes can enhance efficiency, optimize resource utilization, and improve patient outcomes.
