11 About the QA MIL Program Package

This chapter describes QA MIL Package methods and capabilities and provides the information required to get started with running the tool.

11.1 Linkage Rate Calculation

The method for calculating the delivery linkage rate in the Sentinel’s Quality Assurance and Data Characterization Tools is shown in Equation (11.1).

Definition 11.1 (Delivery Linkage Rate) The delivery linkage rate $R$ is defined as:

$$\begin{equation} R=\frac{L}{(L+M)} \tag{11.1} \end{equation}$$

where:

• $L$ is the number of linked deliveries—e.g., a MPatID-ADate pair with evidence of a live birth delivery linked to 1 or more CPatID; and
• $M$ is the number of unlinked deliveries—e.g., a MPatID-ADate pair with evidence of a live birth delivery but no associated CPatID.⁹

11.2 Control Flow Module

In this package, the module execution sequence has been ordered with module stop-gaps as described below.

1. All level 1 checks for existence of tables are performed first and, if any tables do not exist, the process will abort.
2. All Level 1 checks for variables including existence, data type, and length are performed and, if any major issues are detected—i.e., if MPatID or CPatID does not exist—the process will abort.
3. All Level 1 checks for valid values are performed and, if any major issues with the data are detected, the package will abort.
4. All Level 2 checks are performed and, if any major issues with the MIL data are detected, the package will abort.
5. All level 3 and linkage integrity checks are then performed.
