Lean Phase: Solution

Assumption: Patients can correctly and accurately identify their symptoms using USSD compared with what they verbalise to clinicians.

Time Frame: Week 1 (July 1) - Week 3 (July 16) July Projects

Success Metric

Success Metric Point: a kappa score above 0.4 and p value > 0.05 are observed for all symptoms

 

→ Green Light: Proceed to the next stage of research protocol.

 

Orange Light Point: a kappa score above 0.4 and p value < 0.05 are observed for some/all symptoms

 

→ Orange Light: Assess the degree of correlation (using kappa score) qualitatively. This would determine whether the statistical significance is valid in a health setting. This is particularly important for subjective symptoms such as fatigue and pain. Studies have shown that qualitative/descriptive measurement is more sufficient for subjective symptoms.

 

Red Light Point: a kappa score below 0.4 is observed for some/all symptoms and p values < 0.05 are also observed for these symptoms.

 

→ Red Light: Identify why a significant difference in response was observed for the symptom(s). Determine way(s) how the research protocol can be re-designed to improve the correlation. Determine way(s) the USSD system could be refined to eliminate problems.

 

Experiment Build

Technological platforms greatly influence the way a solution addresses the problem of users. As such, in research protocol (RP) stage 2, we are testing whether patients have the knowledge and capacity to communicate their symptoms using phone technology. The patients will use an Unstructured Supplementary Service Data (USSD) system to input information regarding their symptoms. The structure of the USSD questionnaire would resemble the paper survey utilised in RP stage 1. Likewise, 246 patients are asked to access and complete the questionnaire using personal mobile devices prior to their consultation. During or after the consultation,  clinicians are asked to record what symptoms patients described, including their duration and severity, on paper. Therefore, RP stage 2 remains identical as RP stage 1 for clinicians.

 

Correlation Assessment

Since the only difference between RP stage 1 and 2 is the introduction of technology as a medium for conducting questionnaires, the way we assess correlation between patient and clinician responses remains the same. Kappa score test and McNemar Test are utilised to quantitatively evaluate the degree of correlation as well as the statistical significance of differences.
