Capturing structural dimensions of quality

Structure refers to the components that create the health system and includes aspects such as the adequacy of facilities (e.g. does a health facility provide the necessary components for a caesarean section? Are supplies available for resuscitation of the newborn?), management structures, staffing and the overall organisational design of the system.

In some interpretations of the model these are referred to as ‘inputs’ to complement the language of the process and outcomes dimensions. Different surveys and studies can provide information on different aspects of the dimensions. For example:

  • Facility surveys can provide data on the availability of drugs, equipment and supplies but may not provide much information on the organisational and management aspects.
  • Local and national studies and assessments may be available in some countries and may provide a more holistic overview.
  • Tools such as the Johns Hopkins Primary Care Assessment Tool (PCAT) include consumer-client surveys, facility surveys, provider surveys and heath system surveys; which may offer learning opportunities for MNH.
  • The Institute for Health Metrics and Evaluation have supported the use of the Access, Bottlenecks, Costs, and Equity (ABCE) assessment tool in a number of African countries, including Kenya where facility surveys, client experiences, costings and trend data provide a multi-pronged approach to assessing service delivery.

Much of the data from these tools and surveys are  available in quantitative form. We will now look at three examples of how data is collected and compiled. The three examples are:

  1. Service Provision Assessments (SPA)
  2. United Nations (UN) emergency obstetric and newborn care signal functions
  3. Demographic and Health Surveys

Service Provision Assessments (SPA)

The Service Provision Assessment (SPA) survey is a health facility assessment that provides an overview of a country’s health service delivery. SPA surveys collect information on:
  1. Availability of different health services
  2. Proportions of the different facility types which offer specific health services

The core SPA questionnaire reflects generally accepted standards for health care services, WHO and USAID’s service readiness indicators, UNICEF immunisation guidelines, and standards set for MNH care. Several SPA’s have been completed in a number of LMIC’s.

Emergency obstetric and newborn care signal functions

Although often used interchangeably, the terms process indicators and signal functions are distinct.

The 1997 UNICEF, WHO and UNFPA guidelines for monitoring the availability and use of obstetric services introduced a set of six process indicators to measure and monitor key activities that contribute to improved obstetric services. These focused on the provision of emergency obstetrics care; newborn emergency care was added at a later stage. Although referred to as ‘process’ indicators they are primarily structural indicators of quality. The original process indicators are still widely used and include:

  1. Amount of emergency obstetric care (EmOC) services available.
  2. Geographical distribution of EmOC facilities.
  3. Proportion of all births in EmOC facilities.
  4. Met need for EmOC services.
  5. Cesarean sections as a percentage of all births in the population.
  6. Case fatality rate.

Ideal ‘targets’ were set: for example there should be a minimum of one comprehensive EmOC facility and a minimum of four basic EmOC facilities per 500,000 people. The value and relevance of these targets has been questioned particularly in resource poor settings.

The guidelines also identified a set of obstetrics signal functions which are not comprehensive but which are indicatve of a facility’s abilty to provide EmOC. Figure 4.1 below outlines the signal functions and those proposed for newborn care. All EmOC designated facilities are expected to be able to perform six of the basic obstetrics functions whilst comprehensive EmOC facilities must also perform and additional two.

The information is usually collected using facility surveys. There are some limitations with this approach; as with any assessment the findings in some areas are likely to reflect the situation at that particular time.  Additionally the data do capture some processes of care but not its appropriateness. The acceptability of the level of attainment of the signal functions can also be subject to interpretation and require target setting: for example is it necessary to score 100% in all signal functions, and over what period of time?

Demographic and health surveys

Demographic and Health Surveys (DHS) are surveys that are conducted house to house to provide population based data on health and associated socio-economic factors.

The DHS Program conducts nationally-representative household surveys using approaches which are internationally comparable and comparable over time. Generally, funds permitting, a larger survey is conducted every five years and a more focused one in the interim period.

Data on coverage relating to antenatal, delivery and postnatal care are available as well as levels of maternal and neonatal mortality. The DHS Program data also collects an indicator used extensively in MNH, the proportion of deliveries with skilled attendants (health professionals).

The DHS are not the only surveys which provide data on coverage. For example, the Multiple Indicator Cluster Surveys (MICS), conducted by UNICEF provide similar data in some countries. Different methods, definitions and baselines are used in these surveys which may result in two different estimates for the same indicator, so the findings from different types of surveys are not always comparable.

In summary, house to house surveys and facility surveys provide a rich source of data on structural aspects of quality in MNH.  We will turn now to the capture of information on the dimension of process.
