Abstract:
Objective:To develop a small program for pediatric intravenous maintenance drug calculation and evaluate its usability.Methods:The user-built concept was used to develop a small program for pediatric intravenous maintenance drug calculation from August to December 2019. Using the convenient sampling method, a total of 10 nurses in intensive care unit and ward of Department of Cardiothoracic Surgery of Shanghai Children's Medical Center from January to February 2020 were selected as the research objects. The time required for drug calculation and correctness of results were compared for each of two methods (calculation method based on the developed small program and the traditional method based on the calculator) for 200 times. Usefulness, Satisfaction, and Ease of Use (USE) was used to investigate the acceptability of 10 nurses to the new technology to evaluate usability of the small program.Results:The accuracy rate of medicine calculation using the pediatric intravenous maintenance drug calculation small program was 100% (200/200) , which was higher than 88% (176/200) using traditional calculation methods for medicine calculation, and the difference was statistically significant (χ 2=25.532, P<0.01) . The time required for drug calculation using the small program was (15.15±2.74) s, which was faster than (17.09±5.22) s using the traditional calculation method, and the difference was statistically significant ( t=3.451, P=0.001) . The 10 nurses had a high acceptance of the small program and the average score of USE was (6.22±1.03) . Conclusions:The pediatric intravenous maintenance drug calculation program developed in this research can meet the needs of clinical nurses and has a relatively high acceptance. The program can be calculated by the system, effectively avoid the error of manual calculation and save time of manual calculation and double check by nurses, which has good usability.
