Your Current-State Statement
You observe that immunization services depend heavily on paper records and manual follow-up, with vaccinations, schedules, stock, and child information recorded across different tools, making it difficult to maintain one complete view of each child and requiring manual identification of missed appointments and defaulters.
Your Desired-State Statement
You are helping healthcare workers reliably know which children have received vaccines and which need follow-up, while helping caregivers understand when their children should return and experience fewer missed vaccination opportunities.
Your Hypothesized Unmet Need
You hypothesize that healthcare workers and caregivers face an unmet need for reliable, timely, and understandable information about immunization status and next required actions, though the frequency and intensity of this need remain unestablished.
Your Hypothesized Primary Barrier
Fragmented immunization information management (Informational barrier)**
What sustains it: Healthcare workers may rely on paper registers, tally sheets, appointment records, and manual checking of previous entries, which require additional time and effort and may make information harder to retrieve or keep synchronized.
Current workarounds: You and your colleagues may use phone calls or community health workers to locate and follow up children, though you recognize you need to observe actual practices before determining which workarounds are most common.
Who could influence it: Facility managers and health-system managers may influence the processes, reporting requirements, and resources that sustain this barrier, while health-system decision-makers and those responsible for immunization workflows could potentially remove it.
Barrier versus symptoms: You have not yet distinguished whether difficulties with information and processes actually occur as a primary cause of missed follow-up, delays, or additional workload, and you plan to observe the process directly and compare experiences across different facilities to make this distinction.
Your Problem to Solve
You are asking how might we reduce the barriers in accessing, managing, and following up immunization information so healthcare workers and caregivers can move toward timely, reliable vaccination and follow-up for children.
Your observations from public health training, fieldwork, and examination of current immunization recording and reporting processes suggest healthcare workers deal with multiple records and follow-up responsibilities, but you have not yet established whether information and process barriers are a significant cause of the unmet need or whether their frequency and severity make them the primary barrier. You would reframe this problem if evidence shows that information management is not a major difficulty or that other barriers—such as transport costs, distance, vaccine stock-outs, inconvenient facility hours, or other social and operational factors—have a greater effect.
What I Am Still Assuming
- You are assuming that record management, follow-up of missed vaccinations, and reporting may be difficult in some settings.
- You are assuming that these difficulties contribute to missed vaccination opportunities or additional workload for healthcare workers.
- You are assuming that information and process barriers are a significant cause of the unmet need for reliable, timely and understandable information about immunization status.
- You are assuming that immunization information may be recorded and managed through processes that are fragmented, manual, or difficult to keep updated, which makes it harder for healthcare workers to quickly know a child's vaccination history and consistently follow up.
- You are assuming that the frequency and intensity of the need for reliable immunization information have not yet been established across different settings.
- You are assuming that difficulties with information and processes actually occur before concluding they are the main cause of missed follow-up, delays, or additional workload.
- You are assuming that addressing barriers in accessing, managing, and following up immunization information could reduce missed opportunities and unnecessary workload.
