QuickDASH: choosing the optimal method for calculating research results

Objective . One of the most widely used tools for assessing hand function is the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH). To calculate the results of the study, you need to perform several mathematical operations - add up the points according to the patient's answers, divide by the number of answers, subtract one, and multiply the resulting value by 25. It is difficult and time-consuming to do this with a pencil and paper. Therefore, many doctors use a calculator to calculate the results of the study, or make calculations in an Excel. To optimize the calculation process, we have developed a computer program called “Program for assessing functional decompensation of the upper limbs. Purpose of a study: to analyze the effectiveness of the proposed program in comparison with traditional methods of calculating the results of the study using the QuickDASH. Material and methods . An analysis of 10 questionnaires of patients with various hand pathologies was conducted. The patients filled out the questionnaires themselves after a short explanation of the task by the attending physician. Ten medical students took part in calculating the results of the study. The calculation of data obtained as a result of answers to the QuickDASH questions was carried out in three ways: using a calculator, using an Excel spreadsheet, and using a computer program. The total time spent on calculating all 10 questionnaires and calculating the time for each questionnaire separately was determined. Students used smartphones and standard applications as tools for calculations - a calculator, an Excel table, a computer program. Results . Working with the spreadsheet took less time than working with the calculator, but more time than working with the computer program. Conclusion . The conducted research demonstrated the effectiveness of the proposed computer program in comparison with generally accepted methods of calculating data when working with the QuickDASH.
