1) Creating a Markov Mannequin

On this train you’re requested to develop a easy Markov mannequin to foretell the outcomes over a five-year timeframe with a fictitious illness. The illness is asymptomatic in its gentle type and due to this fact sufferers with the illness are identified within the average stage of the sickness. The illness is progressive in nature, which means the severity of illness worsens over time. Annually 5% of sufferers with average illness progress to extreme illness, and 5% of sufferers with average illness die. As soon as sufferers advance to the extreme stage, 50% of sufferers annually die of the illness.

a) Based mostly on the outline above, develop a Markov schematic to characterize the attainable transitions of sufferers with this illness. Make sure you clearly establish the states inside the mannequin and all attainable transitions.

b) Utilizing spreadsheet software program (e.g. MS Excel) design a transition matrix for all of the attainable transitions inside the mannequin.

c) Develop a Markov mannequin which displays the transitions of a cohort of 10,000 people with average illness over a 5-year timeframe. On the finish of 5 years, what number of sufferers have average illness, extreme illness, or have died?

d) Plot the Markov hint for this mannequin.

2) Think about a medical trial has been carried out to guage the cost-utility of a screening programme for colorectal most cancers in comparison with no systematic screening for males aged 60.

Formal screening concerned a one-off display with the purpose of detecting malignancy sooner than in any other case, and follow-up of males (three yearly) recognized with high-risk polyps, indicative of eventual malignancy.

After Eight-years follow-up, the imply High quality Adjusted Life-Years (QALYs) noticed within the screening arm was 5.75 QALYs per affected person and within the no screening arm was 5.70 QALYs per affected person. The price per affected person (screening, follow-up prices, and colorectal most cancers therapy) was estimated as £900 within the screening arm and £500 within the no formal screening arm. After Eight years of follow-up, the common variety of High quality-Adjusted Life-Years (QALYs) for every affected person within the screening arm was 5.75, whereas the common variety of QALYs for every affected person within the no screening arm was 5.70. Prices for screening, follow-up care, and therapy for colorectal most cancers have been estimated to be £900 per affected person within the screening arm and £500 per affected person within the no formal screening arm.

A) Compute the estimated incremental cost-effectiveness ratio (ICER) and characterize the outcomes on the cost-effectiveness aircraft.

B) Is the screening programme cost-effective?
