If we want to collect the data on the health care facilities in our locality, we can go with the indirect oral investigation option. Under this method, the information is not directly collected from the concerned person. It is rather collected from other people or agencies who are likely to have the required information. As it will not be feasible to conduct research on personal basis with 200 families, it will be better to use the data already published by various government, semi- government and reliable private agencies. This will include less cost in terms of time and money involved and we can also seek expert opinion on the same.
