Comparison of effectiveness and time-efficiency between multimedia and conventional counselling on metered-dose inhaler technique education

Abstract

INTRODUCTIONThis study aimed to evaluate whether multimedia counselling (MC) using a touchscreen computer is as effective and time-efficient as conventional counselling (CC) in promoting correct metered-dose inhaler (MDI) technique, with or without the valved holding chamber (VHC).METHODS Participants in the MDI-only and MDI-with-VHC groups were randomly assigned to the MC group or CC group.No blinding was imposed. Inhalation technique was assessed using checklists before and after counselling. Time spent on counselling was determined for all participants, while time taken to perfect the technique was determined only for participants who achieved perfect technique within one hour. RESULTSThe CC group had more elderly participants than the MC group, but the difference was not significant. MDI-only and MDI-with-VHC users showed significant improvement in their inhaler technique after multimedia (44.5 ± 28.0% and 44.1 ± 14.4%, respectively) and conventional counselling (36.8 ± 20.5% and 37.0 ± 14.6%, respectively). No significant difference in MDI technique enhancement was found between the two groups. Although no significant difference was found between the MC and CC groups with regard to the time spent on counselling and the time taken to perfect the technique, the average time spent on counselling was longer for MDI-only users. MDI-only users had 13.5 times the odds of failing to achieve perfect technique compared to MDI-with-VHC users (95% confidence interval 1.50-121.32, p = 0.020).CONCLUSION MC and CC significantly improved MDI technique. Both methods showed comparable short-term effectiveness and time-efficiency in MDI technique education. VHC was beneficial, especially for MDI-users with handlung coordination problems.

Patterns of use of dry powder inhalers versus pressurized metered-dose inhalers devices in adult patients with chronic obstructive pulmonary disease or asthma: An observational comparative study

“…33 According to a recent study, multimedia counseling was as effective and time efficient as conventional counseling in MDIs education. 34 In addition, van der Palen et al showed that the use of video instructions cause an improvement in inhaler techniques when compared to the control group and to those receiving personal instructions. The combination of multimedia and personal instructions is suggested as well.…”

Can a Short Video Improve Inhaler Use in Urban Youth?

“…Additionally, this method may appeal to different learning styles through the use of novel visual aids, decrease face-to-face time required with the provider, and ensure consistency in education provided to patients. 17,21 Furthermore, video and multimedia education is consistent with the digital consecutiveness of the current generation-Generation Z-because these patients have grown up in an entirely digital age. 22 The primary purpose of this study was to determine whether a 5-minute video could be used to educate patients with pediatric asthmatic within the hospital setting.…”

“…Multimedia education has been shown to be more effective than print materials and as effective as provider demonstration in teaching patients inhaler technique. 17,18 Video education has been shown to result in immediate improvement of inhaler technique for children in the outpatient setting, but its utility in the pediatric inpatient setting has not been investigated. 19 Video education has many advantages for use in the inpatient setting.…”

“…Unit prices will be obtained from account records or from local retailers. To measure staff time devoted to pre-ART counseling, we will perform time-motion assessments in line with the Suggested Time And Motion Procedures (STAMP) [80,91,92]. We will sample sufficiently to account for potential sources of heterogeneity such as trial clinic and provider.…”
