A Study to Evaluate a New Jaundice Stick Test

Completed
Conditions
Serum Bilirubin
Jaundice
Interventions
Other: Blood sampling
Registration Number
NCT02926131
Lead Sponsor
University of Oxford
Brief Summary

This is an observational prospective study. The main purpose is to evaluate the stability of the Bilistick system in a humid and hot climate compared to the quantitative test for serum bilirubin (SBR) measurement currently used, the BR-501 total bilirubin meter, kept in a controlled environment.

The secondary aim is to assess the operational feasibility of the Bilistick system in a tropical limited-resource setting, when used by locally trained nurses.

Detailed Description

Study procedure:

1. SBR will be measured in parallel with two tests during three distinct seasons. (Cold, hot, rainy). The Blood is from an extra capillary sample taken from a single heel prick done for routine SBR) BR-501 total bilirubin meter, the quantitative test for SBR currently used, will be kept in a controlled environment while the new bilirubin test (Bilistick system) will be exposed to tropical conditions.

2. Trained nurses will use the Bilistick system observed by a qualified laboratory technician; Usability of the Bilistick system by the trained nurses will be evaluated via a 5-point Likert scale questionnaire and focus groups discussions.

Primary Outcome Measures
NameTimeMethod
Comparison of the agreement of serum bilirubin measurement between the two tests in three different seasons18 months

The main outcome of interest is the potential effect of environmental conditions on the quantitative outcome of the Bilistick System, using BR-501 bilirubin meter machine as a reference. The Bland-Altman analysis will be used to compare the two tests.

Within each season, evaluation of the impact of temporal variation on the agreement of serum bilirubin measurement between the two tests.18 months

A linear regression analysis will be done to look for statistically significant effect of exposure time on the difference between the average total bilirubin serum levels of the two tests.

Secondary Outcome Measures
NameTimeMethod
Evaluation of the usability of the Bilistick system using a 5-point likert scale questionnaire and a focus group discussions18 months

5-point likert scale questionnaire will be filled individually by the trained nurses at the end of each defined season. Quantitative variables related to the secondary outcomes will be measured with the mean, median and ratio according to the distribution of the variable and compared with appropriated statistical test.

Perception by the trained nurses of the Bilistick system usability with a focus group discussion (FGD).18 months

The FGD will be centered around the answers obtained from the questionnaires and the concerns raised by the trained nurses and laboratory technicians during each recruitment period. Qualitative variable from the focus group will be analysed with Nvivo.
