Table 4 Incremental cost effectiveness of syndromic package intervention.

Outcome measure	Control clinics (%)	Intervention clinics (%)	Annualised incremental cost ($)*	Incremental effectiveness (no of patients)†	Incremental cost effectiveness ratio ($/patient)
Correct management	34.5	75.5	17 363	11 508	1.51
Correct treatment	84.1	84.6	17 363	153	113

*This is the net value of all resources (monetary and non‐monetary) required to provide syndromic packages for 1 year to the 20 intervention clinics. It assumes the training has a useful life of 2 ears and is annualised with a 5% discount rate.

†Computed as number of patients with expected outcome when syndromic packages are used less number of patients with expected outcome in absence of syndromic packages. This estimate is based upon an estimated annual patient volume of 28 061 for the 20 intervention clinics.
