Ask an Advisor Answers

Interesting query about free AI tools for public health application including the ability of these tools to conduct needs and capacity assessments, a query I’ve never encountered in all my time as an advisor, but certainly not an unreasonable ask given the ubiquity of AI tools with all sorts of applications. While I didn’t find any resources for you in the CTB I did use my own ChatGPT-5 account to see if I could conjure you up some sort of answer. Here’s my prompt (in using LLMs such as ChatGPT the prompt is the game) based on your query (I took a little license) and the results therefrom, hopefully no hallucinations. The results were prolific so you’ll have to sort through them to see if there is anything useful.

Prompt: I am looking for new AI tools that can be used for various public health applications. Ideally they would be free and be of great assistance in a Needs and Capacity Assessment.

Results: That’s a great question. There is increasing interest and activity in applying AI to public health problems, including needs assessments and capacity assessments. Below I’ll share some ideas and existing tools (free or open-source) you might consider, along with suggestions on how to combine or adapt them. (If you tell me your context — country, level [community, regional, national], and data availability — I can filter further.)

What to look for: functions useful in needs / capacity assessments

Before jumping into tools, here are key AI/enabling functionalities that tend to add value in needs & capacity assessments:

Existing Tools & Platforms You Can Explore

Here are several tools or frameworks (free, open-source, or low-cost) that align with the functionalities above. Some are general AI/ML tools; some are domain-specific

.How to Combine / Layer These Tools in a Needs & Capacity Assessment Pipeline

Here’s a schematic of how you might structure an AI-enabled needs + capacity assessment using a combination of the above kinds of tools:

1. Baseline readiness / capacity mapping
   • Use the PAHO Readiness Assessment Toolkit (or a localized adaptation) to map out existing capacities (data systems, workforce, governance, regulation).
   • Supplement with stakeholder interviews, document review.
   • Use NLP (even off-the-shelf LLMs) to help summarize and categorize document inputs.
2. Data gathering and integration
   • Ingest health facility data, population surveys, demographic data, geospatial layers, environmental data, etc.
   • Use DHIS2 (if relevant in your context) as a backbone for data storage, integration, dashboards.
   • Preprocess the data for missingness, consistency, normalization (use data science toolkits).
3. Exploratory analysis / gap detection
   • Use spatial analysis (SaTScan, GIS software) to find geographic gaps or clusters of need.
   • Use descriptive analytics to compute capacity indicators (e.g. ratio of staff per capita, equipment density, service coverage).
   • Apply anomaly detection or clustering algorithms on multisource data to flag underperforming or underserved areas.
4. Predictive modelling / risk scoring
   • Build models (e.g. via PyHealth or your own ML pipelines) to estimate the risk of service shortfall, disease burden, or resource stress under different scenarios.
   • Use scenario modeling: e.g. “if population grows by 20%” or “if disease incidence rises by 10%,” what capacities will break?
5. Visualization & decision support
   • Create dashboards or interactive visualizations tied to maps, capacity indicators, scenario outputs.
   • Use these visual tools to present to stakeholders, engage communities, validate findings.
6. Iterative validation & stakeholder refinement
   • Hold workshops where stakeholders review the outputs; feed their feedback back into refining models, weightings, or assumptions.
   • Use “explainable AI” techniques (e.g. Shapley values, feature importance) to show what factors drive predicted gaps or risks, so stakeholders can interpret and trust results.
7. Sustainability / monitoring & updating
   • Plan for how to update the models regularly as new data arrive.
   • Use validation tools (e.g. Epic’s open validation or your own local validation protocol) to monitor model performance over time.

Free / Low-Cost AI / LLM Tools You Can Leverage Immediately

In addition to the domain-specific tools above, you can use more general AI / large language model (LLM) tools (many have free tiers) to accelerate specific tasks:

• OpenAI / ChatGPT / GPT-4 / open-source models (e.g. LLaMA, GPT-NeoX, etc.)
  Use LLMs to help with:
  • Writing survey instruments, interview guides, logic models, data analysis plans
  • Summarizing qualitative responses
  • Suggesting relevant indicators, benchmarks, and literature
  • Generating stakeholder mapping templates or gap matrices
  • Proofreading, internal reports
    Just be careful to validate outputs — LLMs can hallucinate or misinterpret domain nuance.
• Topic modeling / NLP toolkits (e.g. spaCy, gensim, Hugging Face)
  Useful for analyzing large volumes of text (e.g. community feedback, open-ended survey answers, policy documents).
• AutoML / no-code AI tools with free tiers
  Some platforms (e.g. Google AutoML, Microsoft Azure’s free tiers, Hugging Face’s open tools) allow you to build simple predictive models without deep coding. These can help with demand forecasting or gap prediction if your data are modest.
• Data visualization tools (e.g. Kepler.gl, Dash, Streamlit, Superset)
  Useful to build interactive maps and dashboards at low cost.

Practical Tips & Considerations

• Data privacy, ethics, and bias: Make sure to anonymize personal data, comply with local laws (e.g. HIPAA, GDPR, or local data protection rules). Be wary of biases in training data that may lead AI to reinforce inequities.
• Stakeholder engagement & “human in the loop”: AI should assist, not replace domain experts. Use stakeholder review to ground-check AI-generated insights.
• Validation & transparency: For any model or analytic output, perform proper validation (hold-out test sets, cross-validation). Use explainability techniques so that the “black box” isn’t opaque to decision-makers.
• Simplicity is okay: You don’t always need deep neural networks. Sometimes simple regression, clustering, or spatial statistics will provide more robust, interpretable, and trustworthy outputs.
• Capacity building: Build local AI / data science capacity so that your assessment isn’t one-off but the start of ongoing analytics. The readiness assessment step helps here.
• Modular approach: Start with a small module (e.g. gap mapping in one domain) before scaling to full-blown AI integration. That way, you can pilot, learn, and adjust.

If you like, I can curate a custom toolset (open-source and free) for your specific country/context (e.g. Indonesia, Kenya, USA, etc.) or for your scale (district, state, national). Would you prefer I build that for you? (FYI, this was ChatGPT asking, not me)

Okay, I think that’s it for now, if you have any other questions don’t hesitate to ask, that’s what we’re here for. Best of success in your public health endeavors, be well, take care, Ask an Advisor.
