Why Decision Support Matters

Growing Data, Persistent Challenge

Immunisation programmes generate increasing volumes of data on coverage, missed children, and service delivery. However, translating this information into timely, prioritised action at the point of care remains a persistent challenge.

Limited Time for Data Interpretation

Frontline workers and programme managers often face limited time for data interpretation.

Fragmented Information and Lack of Structured Prioritisation

Frontline workers and programme managers often face fragmented information across sources and lack of structured prioritisation tools.

Inconsistent Guidance, Suboptimal Follow-Up

Frontline workers and programme managers often face inconsistent application of programme guidance. As a result, outreach and follow-up efforts are not always optimally directed toward the children most at risk.

A Practical Approach to Decision Support

Data is only useful if it leads to action. 

The CDST embedded within VaxyReach is designed to support day-to-day operational decisions by structuring how data is interpreted, aligning recommendations with programme priorities, and supporting consistent decision-making across levels. It focuses on enabling practical, field-level decisions rather than introducing additional analytical complexity.

How the CDST Supports Decision-Making

  • Structured, Context-Aware Guidance
    The CDST provides structured, context-aware guidance to frontline users and supervisors.
  • Priority Attention
    Identify children requiring priority attention.
  • Outreach and Follow-Up
    Organise outreach activities based on operational relevance, and monitor and adjust follow-up actions over time.
  • Nationally Aligned Recommendations
    The underlying logic combines programme guidance with contextual data inputs to generate recommendations that are both usable and aligned with national strategies. Importantly, the CDST is designed to support-not replace-professional judgement.

Operational Integration

A key strength of the CDST lies in how it is embedded within programme workflows. It is integrated into routine data collection and use, aligned with existing supervisory and planning processes, and designed for use in low-resource and low-connectivity environments. This ensures that decision support is not an additional layer, but part of how services are delivered.

Who Benefits

The CDST is used across multiple levels of the health system.

Community-Level Actors

Support identification and prioritisation of children.

Health Facility Teams

Strengthen outreach planning and follow-up.

District-Level Managers

Enable performance monitoring and adaptive management.

What Makes the Difference

The value of the CDST does not lie in the existence of algorithms alone, but in its operationalisation.
Its effectiveness is driven by:

Alignment with national programme logic

Usability in real working conditions

Integration into existing systems and workflows

Continuous adaptation based on field use

This ensures that decision support translates into measurable improvements in how services are delivered.

Why Decision Support Matters

By strengthening how decisions are made at the last mile, the CDST contributes to:

More consistent identification of underserved children

Better prioritisation of outreach efforts

Stronger continuity in follow-up

Improved equity in access to immunisation services

It provides a practical mechanism to operationalise equity commitments, including those set out in the Immunization Agenda 2030.

GaneshAID’s CDST supports frontline actors in turning data into operational decision-making to reach children who are still left behind.
