Abstract
|
|
|
Purpose: This study was done to develop and evaluate a drug dosage calculation training program using cognitive loading theory based on a smartphone application. Calculation ability, dosage calculation related self-efficacy and anxiety were measured.
Methods: A nonequivalent control group design was used. Smartphone application and a handout for self-study were developed and administered to the experimental group and only a handout was provided for control group. Intervention period was 4 weeks. Data were analyzed using descriptive analysis, χ2-test, t-test, and ANCOVA with the SPSS 18.0.
Results: The experimental group showed more ‘self-efficacy for drug dosage calculation’ than the control group (t=3.82, p<.001). Experimental group students had higher ability to perform drug dosage calculations than control group students (t=3.98, p<.001), with regard to ‘metric conversion’ (t=2.25, p =.027), ‘table dosage calculation’ (t=2.20, p =.031) and ‘drop rate calculation’ (t=4.60, p<.001). There was no difference in improvement in ‘anxiety for drug dosage calculation’. Mean satisfaction score for the program was 86.1.
Conclusion: These results indicate that this drug dosage calculation training program using smartphone application is effective in improving dosage calculation related self-efficacy and calculation ability. Further study should
be done to develop additional interventions for reducing anxiety.
