Study Details

Study Description

Brief Summary

This study has two primary objectives. The first is to determine if it is feasible and reliable for children and families with a diagnosis of Neurofibromatosis Type 1 (NF1) to use of blood pressure (BP) monitor at home.

The second is to determine if there is a difference between a child's measured home BP using standard instructions or using a clinical hypnosis script. This will be determined by a randomised control trial design.

Standard and hypnosis Home BP will be compared to the gold standard measurement of BP measured by a trained health care professional in clinic.

Children who participate will complete a clinic-based BP with a health care professional, then will be randomised into either the standard home BP measurement or using a hypnosis script prior to BP measurement.

Detailed Description

Neurofibromatosis Type 1 (NF1) is a rare autosomal dominate genetic disorder that affects an estimated that 1 in 2500 people or 10000 Australians. NF1 affects multiple systems throughout the body. The prevalence of hypertension(HTN) in children and adolescents in the general population is approximately 3.5%. Children and adolescents with a diagnosis of NF1 have an increased incidence of HTN, and has been documented as high as 6.1% to 12%. This is two times higher than the general population.

Clinical adherence to the recommendation of recording annual blood pressure on patients has not been audited. The anecdotal experience of the authors is that most children do not have annual blood pressure (BP) measurements. With the increased uptake of telehealth following the COVID-19 pandemic, children and families may not be reviewed in person for significant periods of time as they prefer consultations over telehealth. As a result, children may miss having their annual blood pressure measured. As a young people with a diagnosis of NF1 have twice the risk of HTN, annual BP measurement is essential.

The American Academy Paediatrics guideline outlines the best practice for BP measurement to ensure true BP reading: The child should be seated in a quiet room for 3-5 minutes before measurement, with back supported and feet uncrossed on the floor. The blood pressure should be measured on the right arm, using the correct sized cuff. This should be completed by a trained clinician. As part of this study, all participants will have a manual sphygmomanometer in clinic-based BP taken on day of recruitment.

One of the primary objectives of this study is to determine if is feasible to use home blood pressure monitoring to screen children with NF1 for hypertension.

Clinical Hypnosis is used as a non-pharmacological technique for reducing procedural anxiety, distress and discomfort with patients. Hypnosis scripts have been successfully used as non-pharmacological adjuncts to reduce pain and anxiety in adult patients undergoing interventional radiological procedures, demonstrating that the benefits of hypnosis techniques can be accessible to patients with little or no training or preparation. Furthermore, healthcare workers who are not experts in hypnosis can be trained to deliver scripts effectively.

If a hypnosis script used while taking home blood pressure readings allows for a calm child and an equivalent clinic BP measure, hypnosis script and home BP monitoring could have greater application across the Royal Children's Hospital.

Therefore the second aim of the study is to see if there is a difference in a child's BP measurements comparing a standard home BP measurement or utilising a calming hypnosis script prior to home BP measurement. This will be compared to the gold standard clinic-based BP measurement completed by a trained professional. The child's self-reported level of anxiety using the Children's Anxiety Meter Scale (CAM-S) will be measured after every BP measurement. In addition, family's perceptions of the process of home BP monitoring will also be collected.

Other: Group 1: Standard Blood Pressure measurement at home

Standard home blood pressure measurement at home

Other: Group 1. Standard Home Blood Pressure Measurement
Measurement of Blood Pressure using Home blood pressure monitor

Experimental: Group 2. Hypnosis script prior to Home Blood Pressure measurement

Participant listens to a pre-recorded hypnosis script (approx 5 mins long) prior to standard home blood pressure measurement.

Outcome Measures

Primary Outcome Measures

  1. Day 1. Clinic-based manual sphygmomanometer blood pressure measurement [Day 1. Day of recruitment at the clinic appointment]

    Three measures of Systolic/diastolic reading (mmHg) using manual sphygmomanometer by trained professional. Following The American Academy Pediatrics guidelines for best practice for blood pressure (BP) measurement to ensure true BP reading.

  2. Day 1. Clinic-based automatic oscillometer blood pressure measurement [Day 1. Day of recruitment at the clinic appointment]

    One reading of systolic/diastolic reading (mmHg) using automatic oscillometer BP monitor by trained professional - Following The American Academy Pediatrics guidelines for best practice for blood pressure (BP) measurement to ensure true BP reading.

  3. Day 2 Home automatic oscillometer blood pressure measurement [Day 2 at home]

    Daily measurement of systolic/diastolic (mmHg) home blood pressure(BP) reading (once only) using an automatic home oscillometer BP monitor measurement.

  4. Day 3 Home automatic oscillometer blood pressure measurement [Day 3 at home]

    Daily measurement of systolic/diastolic (mmHg) home blood pressure(BP) reading (once only) using an automatic home oscillometer BP monitor measurement.

  5. Day 4 Home automatic oscillometer blood pressure measurement [Day 4 at home]

    Daily measurement of systolic/diastolic (mmHg) home blood pressure(BP) reading (once only) using an automatic home oscillometer BP monitor measurement.

Secondary Outcome Measures

  1. Day 1. Clinic-based Children's Anxiety Meter Scale (CAM-S) [Day1 in clinic]

    Measurement of participant's reported state of anxiety in clinic when completing BP measurement using Children's Anxiety Meter Scale (CAM-S). CAM-S is a state of anxiety patient reported measure. It is coded 0-10 across a vertical analogue scale. 0 = calm, not nervous or worried 10 = very very nervous and worried

  2. Day 2,3 and 4 Daily Children's Anxiety Meter Scale (CAM-S) score [Daily on Day 2, 3 and 4 at home.]

    Daily measure of the participants reported state of anxiety when completing BP measurement at home using Children's Anxiety Meter Scale (CAM-S). CAM-S is a state of anxiety patient reported measure. It is coded 0-10 across a vertical analogue scale. 0 = calm, not nervous or worried 10 = very very nervous and worried

  3. Day 2 Children's Anxiety Meter Scale (CAM-S) score [Day 2 at home.]

    Daily measure of the participants reported state of anxiety when completing BP measurement at home using Children's Anxiety Meter Scale (CAM-S). CAM-S is a state of anxiety patient reported measure. It is coded 0-10 across a vertical analogue scale. 0 = calm, not nervous or worried 10 = very very nervous and worried

  4. Day 3 Daily Children's Anxiety Meter Scale (CAM-S) score [Day 3 at home.]

    Daily measure of the participants reported state of anxiety when completing BP measurement at home using Children's Anxiety Meter Scale (CAM-S). CAM-S is a state of anxiety patient reported measure. It is coded 0-10 across a vertical analogue scale. 0 = calm, not nervous or worried 10 = very very nervous and worried

  5. Day 4 Children's Anxiety Meter Scale (CAM-S) score [Day 4 at home.]

    Daily measure of the participants reported state of anxiety when completing BP measurement at home using Children's Anxiety Meter Scale (CAM-S). CAM-S is a state of anxiety patient reported measure. It is coded 0-10 across a vertical analogue scale. 0 = calm, not nervous or worried 10 = very very nervous and worried

  6. Day 4, Study specific survey of parents/caregivers perceptions [Day 4 only]

    Study specific survey. Likert scales used to assess parent/caregiver perception with ease of use of home BP monitor, timeliness to complete measures and interference with family life compared to attending hospital appointment, ease of receiving and returning equipment, and financial cost to attend hospital appointment. Data will be reported for each item individually, as the proportion of parents/caregivers who responded positively on the Likert scale, where higher scores indicate less favorable responses.
