In a recent study my undergraduate student and I reviewed the path followed by DONATED MALARIA DRUGS IN RIVERS STATE between 2014/2015. Results show that the distribution points (the PHC centers inclusive) had little role to play in the accessibility of drugs.
1- the immediate past Governor of the Rivers State bought drugs that were being exorbitantly sold at duly registered pharmacies and drugstores in the state rather than donated to patients at PHC and in communities.
2. Governor Rotimi Amaechi CUSTOMIZED the drugs by printing his photograph on them and they were left to expire in storage, wasted effort, resources and lives. Some reasons given to justify this tragedy were that there was no demand from the beneficiaries, no fueled vehicle to take the drugs to destination before expiry date
3- The contribution of Primary Health Care Service providers to non accessibility was the indiscriminate donation of drugs to both patients who could afford and those who could not afford their cost. In the event of an industrial strike, the distribution officers dispensing these malaria drugs did not relinquish the store keys for donation to continue while they are on a strike
You are in Nigeria like me so our study may guide you.
That question is not specific to Malaria treatment. It concern in general the Evaluation of drug accessibility in health centers. It based on the master of the disease epidemiology, the master of drug prescription and his cost (financial access) and the drug chain distribtion (geographic access) in each country.
One good indicator to evaluate the accesability to malaria treatment in PHC is the proportion of cases treated in the first 48 h from the beginning of symptoms.
