Abstract

Background

Appropriate information about the benefits and risks of invasive procedures is crucial, but limited data is available in this field. The aim of this study was to evaluate the incremental value of a short video about coronary angiography compared with standard information, in terms of patient understanding, satisfaction and anxiety.

Methods

This prospective multicenter study included patients admitted for scheduled coronary angiography, who were randomized to receive either standard information or video information by watching a three-dimensional educational video. After information was delivered, patients were asked to complete a dedicated 16-point information questionnaire, as well as satisfaction and anxiety scales.

Results

From 21 September to 4 October 2015, 821 consecutive patients were randomized to receive either standard information (n = 415) or standard information with an added educational video (n = 406). The information score was higher in the video information group than in the standard group (11.8 ± 2.8 vs 9.5 ± 3.1; P < .001). This result was consistent across age and education level subgroups. Self-reported satisfaction was also higher in the video information group (8.4 ± 1.9 vs. 7.7 ± 2.3; P < .001), while anxiety level did not differ between groups. The variables associated with a higher information score were the use of the educational video, younger age, higher level of education, previous follow-up by a cardiologist, prior information about coronary angiography and previous coronary angiography.

Conclusions

In comparison with standard information, viewing a dedicated educational video improved patients' understanding and satisfaction before scheduled coronary angiography. These results are in favor of widespread use of this incremental information tool.

Study design

This study (registered with ClinicalTrials.gov identifier NCT02484144) was a prospective, multicenter national trial, involving 39 interventional centers in France, aiming to show the superiority of ‘video information’ compared with ‘standard information’. The standard information consisted of standardized oral information and a national standard written form. In the video information arm, patients received the standard information but additionally watched an educational video. Each strategy

Population

From 21 September to 4 October 2015, 1825 consecutive patients were admitted for coronary angiography, of whom 843 were included in the study. These were randomized to receive either the standard information or the video information. After exclusion of 22 incomplete or unusable questionnaires, the final study population comprised 821 patients (standard information group, n = 415 and video information group, n = 406) (Figure 1).

For the 39 participating centers, 821 patients were included with a

Discussion

This study provides new data about delivering information to patients before coronary angiography in everyday clinical practice. The objective evaluation of their level of understanding using a dedicated questionnaire showed potential for improvement. There were three key study findings: (i) the understanding of information was significantly better after viewing an educational video on a tablet, compared with when standard written information alone had been delivered; (ii) patient satisfaction

Conclusion

The results of this study suggest that a significant increase in patient understanding of and satisfaction with information provided on coronary angiography can be achieved using a dedicated educational video. Video support is particularly easy to broadcast on TV or internet sites and can potentially be made widely available. Further versions of the video could be developed in other languages, and for other invasive procedures in cardiology or in other medical fields.

Of all the studies included in the systematic review, fourteen of these evaluated the use of an educational video on patient anxiety (Sun et al., 2020; Lattuca et al., 2018; Torabizadeh et al., 2021; Xia et al., 2019; Pearson et al., 2005; Wouters et al., 2019; Hu et al., 2020; Ayasrah and Ahmad, 2016; Ahlander et al., 2018; Ketelaars et al., 2017; Ruffinengo et al., 2009; Tugwell et al., 2018; Rigatelli et al., 2009; Habibzadeh et al., 2018) thirteen assessed its effect on patient satisfaction (Bowers et al., 2017; Sun et al., 2020; Lattuca et al., 2018; Jamshidi et al., 2013; Xia et al., 2019; Pearson et al., 2005; Wouters et al., 2019; Hu et al., 2020; Ahlander et al., 2018; Ketelaars et al., 2017; Ruffinengo et al., 2009; Tugwell et al., 2018; Rigatelli et al., 2009) and eleven studies evaluated both variables (Sun et al., 2020; Lattuca et al., 2018; Xia et al., 2019; Pearson et al., 2005; Wouters et al., 2019; Hu et al., 2020; Ahlander et al., 2018; Ketelaars et al., 2017; Ruffinengo et al., 2009; Tugwell et al., 2018; Rigatelli et al., 2009). Patients’ anxiety was also assessed in three studies (Jamshidi et al., 2013; Ayasrah and Ahmad, 2016; Rigatelli et al., 2009) through hemodynamic parameters: blood pressure and heart rate.

      Accordingly, the level of patient satisfaction increased using the orientation tour. Lattuca et al also showed that watching an educational video improved patients' understanding and satisfaction compared with the routine care given to patients.13 Patients in the intervention group were more satisfied than the patients in the control group.
