There were several conditions in which the Intervention would be considered cost-saving.
The probability that MobileMums is cost-effective is given by the proportion of pairs of incremental costs and benefits at which the intervention would be considered cost-effective.
Although there is no consensus on a specific cost-effectiveness threshold, below which an intervention would be considered cost-effective, one suggested heuristic has been to use the country's per capita GDP (WHO, 2001).
According to the World Health Organization's pharmacoeconomic evaluation criteria, if the incremental cost effectiveness ratio is found to be within three times the per capita income of that region then the intervention would be considered cost-effective [ 42].
20, 21 Following this recommendation, any new intervention would be considered cost-effective if it were below the recommended value of three times the GDP per capita threshold of MYR 66,704 (USD 20,845).
23 Residents who scored below 5 or over 16 on the Barthel index were excluded from the study on the basis that the intervention would be considered too intense or insufficient for their needs, respectively.
We used the proposed willingness-to-pay threshold of 500 000 NOK (≈$830000) per YLS to signify the amount below which an intervention would be considered 'good value for money' (Norwegian Directorate of Health, 2007).
The aspects that address these two scales relate to: 1) treatment rationale, 2) treatment satisfaction, 3) degree to which I would recommend to a friend who had the same problem, 4) extent to which is considered to be useful in the same case, 6) extent to which the intervention would be considered aversive.
Results from sensitivity analyses suggest that adding RUSF to a Food Assistance (FA) intervention would be considered cost-effective compared to FA alone, if society were willing to spend between approximately 1,000 and 2,000 EUR per episode of diarrhea averted, and between 4,000 and 40,000 EUR per case of anemia averted.
