At PSI, one manner in which we assess the health impact of our programs is by estimating the number of disability-adjusted life years (DALYs) our interventions have averted. In cases where PSI does not directly implement all aspects of a particular intervention, but still plays a role in the distribution, delivery or promotion of that intervention, PSI employs specific policies and procedures to estimate health impact. Through these policies, PSI is able to estimate impact generated from partnerships and communication activities.
‘Significant Involvement’ refers to PSI’s active contribution to a partner’s service delivery or free malaria net distribution campaign. PSI may be considered ‘significantly involved’ in a partner’s efforts when specific criteria are met surrounding contractual agreements, provider training, quality assurance, facility improvement, or ongoing support, among others. When PSI can be considered significantly involved in a partner’s efforts, PSI claims 100% of the DALYs averted by the intervention. If PSI cannot demonstrate significant involvement, no impact will be claimed.
PSI’s health promotion and communication activities sometimes increase demand for health services that PSI does not directly deliver. In these cases, the health communication activities serve as referrals to health services. If PSI can demonstrate that a person received a service as the direct result of PSI’s communication efforts, PSI attributes 50% of the health impact resulting from that service to PSI’s efforts.
Four policies govern PSI’s attribution of DALYs averted through Significant Involvement or Service Referral:
- Policy for impact attribution: Service delivery through partners
- Policy for impact attribution: Referral for service delivery
- Policy for impact attribution: Partnership in LLIN campaigns
