Lean Phase: Solution

Assumption: mHealth algorithm (currently in development) will be able to produce the same medical advice as what clinicians would offer when provided with identical symptoms.

 

Time Phase: 2 weeks - October 28th to November 11th 

 

Success Metric

Success Metric Point: null hypothesis is accepted

 

→ Green Light: Proceed to the next stage of research protocol, which is dissemination of results..

 

Red Light Point: null hypothesis is rejected

 

→ Red Light: the algorithm is re-assessed in terms of its weighting for symptoms and personal details.

 

Experiment Build

Research protocol (RP) stage 4 involves processing all data points gathered in stage 3. Specifically, all patient symptoms are input through the triage algorithm. The output from the algorithm is compared with the medical advice given and recorded by the clinician.

 

Accuracy Assessment

The accuracy of the triage algorithm is assessed by performing a proportionality z-test. The resultant p-value will determine whether algorithmic outcomes are statistically different from clinicians’ advice.

 

The expected proportionality is determined to be 0.57 (an average of triage accuracy of 23 mHealth apps). Thus, it is reasonable to hypothesise the accuracy rating of the algorithm will be around 60% (p= 0.6).

 

Null hypothesis (H0): The algorithm offers medical advice to a sufficiently accurate extent compared with clinicians.

 

Alternate hypothesis (H1): The algorithm does not offer medical advice to a sufficiently accurate extent compared with clinicians.
