Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This trial is to test the effectiveness of a communication technique Teachback - which is for checking and ensuring understanding in a non-shaming way and involves asking a person to explain in their own words what they need to know. Teachback will be used by nurses staffing the Pregnancy, Birth & Baby Helpline (PBB) – a government funded telephone parenting service (Healthdirect Australia). Implementation of this method is to improve service delivery and health communication for the PBB Helpline.

This is a stepped wedge cluster randomised trial in which all nurses will be invited to participate in the study and will cross over to the intervention according to a training schedule. The duration of the study period is 6 weeks, with nurses randomised to receive the training at 2 weeks or 4 weeks.

Each group of nurses will attend a single two-hour face-to-face training session according to the study schedule. This will take place on site at the call centre and will be delivered by an experienced trainer who has led a previous study on Teachback and has expertise in running Teachback training sessions. Sessions will be co-facilitated by a researcher closely involved with study design, and will be attended by the manager, supervisor, and clinical trainer of the telephone service.
The training schedule will include:
- Background evidence for Teachback.
- How to do Teachback and examples of phrases.
- Videos with Teachback in different contexts.
- Interactive activities that include role plays and scenarios.

In addition, flyers about the study will be placed around the call centre to promote the study and training sessions to nurses. Reminder emails about the use of Teachback and helpful strategies will be sent to participating nurses intermittently.

Both nurses and callers to the PBB Helpline are participants and the intervention will be evaluated by both interviewing callers and feedback from the nurses. Callers to the PBB Helpline will be interviewed one week after their initial call by an independent organisation. Nurses will be asked to reflect on their communication during their calls by completing a short survey during their shift.

Comparator / control treatment
This is a 6-week stepped wedge cluster randomised trial in which all nurses will act as their own controls. Initially all nurses will be providing usual care. After two weeks half of the nurses (Group 1) will receive training in Teachback. Two weeks after that the remaining nurses (Group 2) will cross to the intervention arm, so that all are providing the intervention.

Minimum age
16 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Participants will be excluded from the study if they are unable to speak adequate English as we do not have access to interpreting services for the study.
Individuals whose call requires transfer to nurse triage for an emergency, a counsellor for psychological support or translator will not be invited to participate. Callers on sensitive topics (e.g. termination, miscarriage) are excluded and calls that are less than 4 minutes duration.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Nurses will be aware of their allocation to either Group 1 or Group 2.
Pairs of nurses will be matched and stratified according to average weekly hours worked. Nurses will be allocated to a group by The University of Sydney researchers by an electronic generation of a random number sequence.

An independent organisation will be interviewing the participant callers and they will not be aware of the group allocation, nature of the intervention or the study design.

Initially participant callers in both the intervention and control groups will be informed that they are participating in an evaluation of the PBB Helpline. A written debrief statement will be emailed to participants after the study is complete explaining that the PBB Helpline want to improve their service and that a trial of Teachback was conducted to see if it was effective.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation technique using Excel RAND function.

Efficacy
Statistical methods / analysis
The analysis will be to test for differences between Teachback and usual care on a range of measures, including knowledge perception and confidence. Participant’s health literacy level will be assessed with a single-item screener, so we can assess separately if there is a difference between the two conditions for participants with low health literacy.

Specific details of the sample size calculations include:
- The standardized effect size is 0.5
- Power: 80%
- Significance Level: 0.05 (5%)

N = 16 clusters (nurses)

There is the assumption that each cluster handles a minimum of 5 calls in each arm.
Sample size calculations suggested the number of participants needed is 400 (callers) however to be able to detect effects in the secondary outcomes it’s is worthwhile recruiting more participants. A larger sample size will allow for dropouts or non-participation. So the number of participants needed for our study is 600 and oversampling participants allows for fewer nurses participating and in the event that nurses don’t provide the minimum number of calls. We cannot predict ahead of time what will happen with the nurses.

Additionally, our primary outcome is an adapted measure and we don’t have data for this population, so it is reasonable to oversample.

Summary
Brief summary
This study is trialing the Teachback method to improve service delivery and health communication for the government funded telephone parenting service (Pregnancy, Birth & Baby Helpline, Healthdirect Australia). The primary outcome is assessing the effectiveness of Teachback compared with the usual care delivered through the PBB Helpline on a range of topics, testing chiefly if knowledge, understanding and satisfaction has increased by the Teachback intervention.

This is a stepped wedge cluster randomised trial in which all nurses will be invited to participate in the study and will cross over to the intervention according to a training schedule.

Both nurses and callers to the PBB Helpline are participants and Teachback will be evaluated by both interviewing callers and feedback from the nurses. Callers to the PBB Helpline will be interviewed one week after their initial call by an independent organisation. Nurses will be asked to reflect on their communication during their calls by completing a short survey throughout their shift. Nurses will also be invited to provide further feedback about the study through qualitative interviews/focus groups.
