Smartphone App Education pertaining to Patient Controlled Analgesia Use and Pain Management after Spinal Anesthesia for Lower Extremity under Orthopedic Surgery

Abstract

Purpose The purpose of this study was to develop a smartphone app for use in patient controlled analgesia (PCA) education and to identify PCA knowledge and pain management following lower extremity orthopaedic surgery under spinal anesthesia in patients who received smartphone app education. Methods Participants were 150 patients in an orthopaedic hospital located in Busan. The measurement variables used in this study were PCA knowledge, pain management and pain level. For data analysis, SPSS/WIN 21.0 program was used in the analysis of the relation of frequencies. In addition, percentage, mean and standard deviation, t-test, ANOVA, Duncan, Pearson's correlation coefficients were also assessed. Results The score for knowledge regarding PCA was 4.27±1.64. The correlations between knowledge and pain management (button push times <under 8 hours, button push times, from 8~24 hours, and self-efficacy for PCA use) were r=.46, p<.001; r=.34 p<.001; r=.53 p<.001. Conclusion The findings show that education on PCA using a smartphone app is an effective method for pain management in patients after surgery. Development and active use of smartphone apps to manage pain for patients in a variety of other surgical departments is recommended. 주요어: 스마트 폰 앱, ìžê°€í†µì¦ì¡°ì ˆê¸° 사용 지식, 통증관리 Key words: Mobile application, Analgesia, Patient-controlled analgesia, Knowledge, Pain management
