Lean Phase: Solution

Assumption: The positive correlation result in RP stage 2 withstands with a larger sample size of over 1000 individuals.

Time frame: 24th July - October 28th

Success Metric

Success Metric Point: a kappa score of 0.4 or greater 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 of 0.4 or greater 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.

 

 

Experiment Build

Development of an effective self-triage system that provides accurate medical advice requires collecting a large quantity of symptom data. As such, RP stage 3 primarily aims to collect a much larger quantity of patient and clinician data through automating data collection and entry on clinicians’ end. This is achieved through asking clinicians to record patients’ symptoms (as well as duration and severity) using USSD. At the same time, we also want to determine whether a positive correlation withstands within a large sample size of greater than 1000 data points.

For patients, the methodology remains identical as RP2 – their symptoms and associated details are digitally entered through USSD prior to their consultation. To encourage usage, the USSD system can be accessed without a fee. However, since the number of data points required is much greater, encouragements for participating in the USSD questionnaire from clinicians are essential. PERA will facilitate this process by distributing detailed instructions throughout clinics to help patients access and complete the digital survey.

 

To assist and enhance the user experience of USSD for clinicians, a training day will be conducted at the beginning of RP stage 3.

 

Correlation Assessment

Correlation between patient and clinician responses is assessed through kappa score test and McNemar Test.

 

Overall, RP3 will be executed without any in-person assistance from PERA as collection of survey data will be automated for both patients and clinicians. This is ideally executed during the months that Project Everest is not operating in Blantyre e.g. March to June. During this period, an Australian point of contact will be provided.
