Studies using a gross-costing approach frequently collect retrospective data from accounting databases, tariff books, market prices, or published studies.
Their database contains detailed tariff data at ISIC 3-digits (International Standard Industrial Classification) from 1974 to 2001.
In our database, we also have missing tariff and trade data for a given group of countries and products that affect the independent variables.
High performance, scalability, fault tolerance, and cost effectiveness are facilitated through data partitioning, data replication strategies, multi-node structures, and pay-per-use tariff systems, respectively, through a cloud-based NoSQL database.
These will be collected from hospital accounting databases, national tariffs and official wage and price lists.
31 Drug tariffs were derived from a Spanish drug cost database.
Precise data on health care expenditure were obtained from a merge of Health Search CSD-LPD database with data on costs and tariffs of drugs, outpatient visits, diagnostic tests, and hospitalizations from the SiSSI Project.
Since we aimed to obtain nationally representative estimates, we assigned hospital costs to each admission in the database based on the nationally defined reimbursement tariff which applies when a patient is treated outside their region of residence.
Pregnancy status was determined from the databases mentioned above by using disease and tariff codes for different conditions and procedures indicative of ongoing pregnancy or the completion of pregnancy (26 ) (Table 1).
Data sources for the variables being used in a cost-effectiveness model may be clinical trials, literature (e.g. meta-analysis), databases, medical records, Delphi panels and/or official tariff lists.
