Table 1 Terms and definitions of data availability, quality and utility assessed by study objectives. EN-BIRTH Baseline Register Analysis
Study Objective | Term | Definition |
|---|---|---|
Objective 1: Data Availability | Availability | A measure of whether the specific data element is recorded in the register in relation to register design [8, 19] |
Completeness | A measure of the proportion of entries in the register that had any data recorded for the specified data element for: Numerator – women or babies for whom intervention received/not received or health outcome of interest recorded Denominator – mothers delivered or babies born [20]. | |
Objective 2: Data Quality | Implausibility | A measure of whether individual data are outside pre-defined ranges of biological credibility. |
Heaping | A measure of the proportion of values falling on specific values (e.g. for birthweight on 2000g or 2500g) or rounded (i.e. ending in “00” or “50”). | |
Internal consistency | A measure of whether the observed relationship between related data elements is as expected [20, 21]. | |
Objective 3: Data Utilization | Utility | The transformation of count data into indicators by using them as numerators and denominators or cross-tabulation. |
Coverage | Number of individuals receiving an intervention or service (numerator), from among the hospital population in need of the intervention or service (denominator) [6]. | |
Impact | A measure of the extent to which health status of the facility target population is being achieved (e.g. maternal and newborn mortality); used for global tracking [22] . |
