Abstract: Objective: To compare and evaluate the safety and cost-benefit of the manual and intelligent venous blood collection in outpatient area. Methods: The hospital selected had two branches with the outpatient area in Branch A using manual venous blood sampling as the control group and the outpatient area in Branch B using intelligent venous blood sampling as the experimental group. From January to December 2022, both the financial data and data collected from the Business Intelligence (BI) integration platform were calculated and analyzed to test the differences between manual and intelligent venous blood sampling in terms of operation time, safety quality, cost-benefit and service efficiency through on-site investigation, insider interview and project cost method. Results: Compared with manual venous blood sampling, the registration [(10.83±4.54) s vs (31.68±14.36) s], sorting [(3.78±1.28) s vs (12.60±10.12) s] and total time of intelligent venous blood collection [(61.34±17.79) s vs (90.54±37.20) s] were less, the total cost of the project was higher [(26.77±4.93) yuan/case vs (23.95±4.72) yuan/case], the labor cost was lower [(4.76±0.20) yuan/case vs (5.71±0.35) yuan/case], and the differences were statistically significant (P<0.05). The rate of barcode, collection and submission quality problems of manual blood sampling is higher than that of intelligent blood sampling, the service efficiency of nurses applying intelligent venous blood sampling system was as high as 112.07%, and the cost-benefit of both venous blood sampling methods were negative. Conclusion: Intelligent venous blood sampling project is more optimized with shorter operation time, less blood sample quality problems and higher nursing service efficiency. However, the current charging standard is lower than the cost of venous blood sampling. It is thus suggested to appropriately increase the charging standard of venous blood sampling to promote a positive incentive mechanism focusing on realizing the value of technical services.
