Introduction [back to top]

The System of Health Accounts (SHA) 2011 provides a standard for classifying health expenditures according to three (3) axes: consumption, provision, and financing. It gives guidance and methodological support for the compilation of health accounts, which seeks to describe the health care system from an expenditure perspective both for international and national purposes. The SHA 2011 is the international standard for health accounting (OECD, Eurostat, and WHO 2011) which presents a multi-dimensional approach to analyze the structure of health in a country.

The SHA-based Philippine National Health Accounts (PNHA-SHA) not only provides the Total Health Expenditures (THE) of the country, but it also differentiates between two (2) aggregates of health, namely Current Health Expenditures (CHE) and Health Capital Formation (HK). PNHA-SHA consists of a total of 46 tables; 35 tables on CHE, three (3) on HK and eight (8) on derived indicators. These tables contain 12 health expenditure classifications defined as follows:

General Methodology [back to top]

1. The Philippine National Health Accounts based on the System of Health Accounts 2011 (PNHA-SHA) measures expenditures for the final consumption of health goods and services. It covers expenditures on activities with the primary purpose of improving, maintaining, and preventing the deterioration of health and mitigating the consequences of ill-health of individuals in the Philippines for a given year through the application of qualified health knowledge. The health accounts boundary is determined based on the following criteria: (a) primary purpose, (b) use of qualified health knowledge, (c) expenditure for resident persons (spatial boundary), (d) expenditure incurred in a specified year (time boundary), and (e) transacted (produced and paid for).
    
2. Current health expenditures (CHE) and health capital formation (HK) are estimated as two separate aggregates of the PNHA-SHA.
    
3. Health expenditures are classified into 12 schemes. The expenditure classifications under each of the three major dimensions of SHA 2011 are listed as follows:

Financing Dimension

- Financing sources (FS): the revenues of the health financing schemes received or collected through specific contribution mechanisms;
- Institutional units of financing sources (FS.RI): institutional units that provide revenues to health financing schemes (a “Reporting Item” or RI under the FS dimension);
- Financing schemes (HF): components of a country’s health financial system that channel revenues received and use those funds to pay for, or purchase, the activities inside the Health Accounts (HA) boundary;
- Financing agents (FA): institutional units that manage health financing schemes.

Provision Dimension

- Healthcare providers (HP): entities that receive money in exchange for or in anticipation of the provision of the activities inside the health accounts boundary;
- Factors of healthcare provision (FP): the types of inputs used in producing the goods and services or activities conducted inside the HA boundary;
- Capital formation (HK): the types of assets that health providers have acquired during the accounting period and that are used repeatedly or continuously for more than one year in the production of health services.

Consumption Dimension

- Healthcare functions (HC): the types of goods and services provided and activities performed within the health accounts boundary;
- Beneficiary characteristics: the attributes of those who receive health care goods and services or benefit from health activities performed within the HA boundary – e.g., age/sex (AGE), income quintile group (INC), disease group (DIS), and region of residence (REG).

4. There are particular health expenditure items that could not be classified into the given schemes above due to lack of detail in the existing data. The breakdowns of these expenditure items are estimated using percentage distributions referred to as distribution keys. Distribution keys were prepared using data from research studies, statistical reports, administrative reports, censuses, household survey tabulations, and/or other data sources.
    
5. Health expenditures classified under the schemes mentioned above are reported and summarized in a series of two-dimensional tables.

Health Expenditure in the PNHA-SHA is compiled by component. Components generally correspond to financing agents (FA) or subcategories of FAs. The components have been primarily defined to correspond to expenditure core data sets. These are the same core data sources used in the previous version of the PNHA. The succeeding notes describe the coverage, data sources, estimation methods, and distribution keys data sources by component of the health expenditures of the PNHA-SHA.

 

I. National  government  (Department  of Health) / Domestic revenue based [back to top]

Source Agency and Publication/ Data Inputs:

- PSA: 2018 Supply and Use Tables

- Average expenditures per establishment by employment size and industry group from Racelis (2014) study on private establishments health spending for employees

Estimation Methodology:

- For the benchmark estimate, health expenditures of private corporations are estimated by multiplying the average health expenditure per establishment with the number of firms by employment size and by industry group for the current year. Total expenditure is estimated as the sum of all expenditures of private establishments across all industries.

- For non-benchmark years, the estimates from the benchmark year is extrapolated with the trend of health inputs by industry, derived by multiplying Gross Value Added with the technical Coefficient of Human Health Intermediate inputs in the 2018 SUT.

Health expenditures for capital outlay in the NEP is scaled up using the ratio between the agency level actual expenditures on capital outlays reported in the BESF and agency level programmed expenditures on capital outlays stated in the NEP.

- For the local government estimate, actual data on capital outlay as reported by BLGF was utilized. The structure of national government was used to break the total capital outlay of LGU by asset type.

- For the private sector estimate, data on CPBI and ASPBI was used to extract the share of health to total construction and durable equipment in NAP.
