Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Sponsor: University Hospitals NHS Foundation Trust
Purpose of study:Evaluate and validate the utility of the mobile Head Circumference application for use in the clinical and outpatient setting for evaluation of head circumference of neonates and infants
Primary objectives:Evaluate usefulness of and feasibility of the application in the clinical setting comparing it to normal practice.
Secondary objectives:Evaluate parent/guardian reliability and satisfaction of the use of the mobile head circumference app.
Study Design:Prospective
Sample Size:Treating clinicians employed by Cambridge University Hospitals NHS Foundation Trust will identify patients eligible for this study (infants \<18 months of age) and notify research team members with the patient's/guardian's consent. Once identified, research team members will approach patients' parents/guardians to seek informed consent before their clinic appointment or at the bedside on the ward. An information sheet will be used. If they choose to participate, we will measure the HC during the clinic appointment or on the ward. (Please refer to Flowchart 1). Sample size estimation was calculated with 90% statistical power to detect a change of means by 1 and a standard deviation of 1. This, along with 10% iteration, equals 33 participants.
Summary of eligibility criteria:Neonatal patients and infants with need of continuous measurement of Head Circumference up to the age of 18months.
Investigational techniques:Mobile application for Automatic measurement of head circumference.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
HC is measured by measuring the widest circumference of the head with a tape measure. Typically, this is performed by health care workers, but parents can be taught to take measurements reliably. With the increasing use of telephone and virtual clinics as a substitute to face-to-face appointments, parental measurement of HC is increasingly used to help guide clinical management in a wide variety of clinical specialties including Neurosurgery, Neonatology, Paediatrics, and General Practice.
Tape measure HC measurements are prone to error, particularly when performed by parents, due to individual differences in head shape, hair style and texture, subject cooperation, and examiner differences in tape measure placement and tautness.6 There is therefore the need for a more reliable method.
Rationale for the study:
We have developed a HC mobile application (HCMA) that can measure the head circumference of an infant and plot it against standardised growth charts.
The rationale of this study is to validate the HCMA in a clinical setting and to review its usability by parents in the community.
Research objective and purpose
The main objective of the study is to validate the accuracy of the HC app and to prove its utility and feasibility in clinical practice.
Secondary objectives will be to evaluate parent/guardian reliability and satisfaction of using the HC app.
Primary Objective:
Hypothesis 1: There is no statistically significant difference between HC measured with a tape measure and HC measured with HCMA;
Secondary Objectives:
Hypothesis 2: Intra-rater Reliability(precision/repeatability) - The variability of series of three measurements of HC using HCMA (performed by a healthcare professional) is within 0.5 cm -(the standard error margin for measurement measurements) Hypothesis 3: Inter-rater Reproducibility - HC measurements made using the HCMA will not be significantly different when measured by parents or healthcare professionals we will then compare measurements of HC using HCMA performed by healthcare professional with the measurements performed by the parents/guardians using the HCMA. These should be within the standard error of margin for the measurement with tape measure.
Hypothesis 4: Parents are satisfied using the HCMA and find it easy to use'
