Decision-support logic

This page describes the decision support logic included in the WHO Digital Adaptation Kit (DAK): SMART Guidelines for Immunizations (link forthcoming).

The decision-support logic component provides the decision logic and algorithms, as well as the scheduling of services, in accordance with WHO guidelines. The decision logic and algorithms in this implementation guide deconstruct the recommendations within the immunization guidelines and guidance into a machine readable format that clearly labels the inputs and outputs that would be operationalized in a digital decision-support system, such as an electronic immunization registry (EIR).

Decision Support Logic Overview

The table below provides an overview of the decision-support tables and algorithms for the different business processes in an EIR. The structure of the decision-support tables is based on an adaptation of the Decision Model and Notation (DMN™), an industry standard for modelling and executing decision logic. These decision-support tables detail the business rules, data inputs and outputs to support EIR business processes.

Should not vaccinate client as client's age is less than 9 months. Check for any vaccines due, and inform the caregiver of when to come back for MCV1. In countries with ongoing transmission in which the risk of measles mortality remains high, MCV1 should be given at age 9 months.

As a general rule, live vaccines should be given either simultaneously or at intervals of 4 weeks. An exception to this rule is OPV, which can be given at any time before or after measles vaccination without interference in the response to either vaccine.

Measles primary series is complete. Two measles primary series doses were administered. Check if a measles supplementary dose is appropriate for the client. An additional dose of MCV should be administered to HIV-infected children receiving HAART following immune reconstitution. If CD4+ T lymphocyte counts are monitored, an additional dose of MCV should be administered when immune reconstitution has been achieved, e.g. when the CD4+ T lymphocyte count reaches 20–25%. Where CD4+ T lymphocyte monitoring is not available, children should receive an additional dose of MCV 6–12 months after initiation of HAART.
