Concern 623 · Working draft · editorial review in progress
Care-management under-coverage
Care-management undercoverage happens when a system fails to offer extra support to people who need it because it mistakes low medical spending for good health.
Understanding the concern
Health services sometimes use a score to decide who gets a care coordinator or extra follow-up. If the score predicts future costs, it may favor people who already have good access to care. Someone who could not afford visits may look inexpensive even while living with serious illness.
A landmark study found this problem in a widely used health-management algorithm. The key mistake was the target: predicting dollars spent instead of health needs. It is like judging how hungry someone is by their restaurant bill. Choosing a better measure can change who receives help, so the question is not only whether the prediction is accurate but what it is predicting.
An example
A patient who has skipped appointments because of transport costs receives a lower support score than a healthier patient with frequent paid visits.
Illustrative unless identified as a documented case.
Evidence and its limits
Obermeyer and colleagues studied a particular commercial algorithm. The mechanism should not be assumed to describe every care-management system.

Broader frameworks and background
These resources provide context. They do not establish every claim in this concern.
A question to discuss
Does this service measure who needs care, or who has historically been able to obtain it?

Virtues and principles to consider
Virtues are qualities we practice in how we treat people and make choices. They are not scores for judging someone. Use these ideas to explore what a thoughtful response could look like.
Service
Service means using abilities and resources to meet real needs. It asks whether the people meant to benefit actually receive help, rather than treating them as a means to another goal.
Speak with the people the project is meant to serve. Notice burdens it may add, such as extra checking or confusing forms. Judge success by their experience as well as the organization's targets.
Ask together: Who is this meant to serve, and do they experience it as helpful?
Dignity
Dignity means recognizing each person's worth regardless of usefulness, status, or a system's score. People deserve respect and a voice in matters that affect them.
Explain important decisions, avoid humiliating treatment, and keep room for a person's story. Do not treat a prediction as a complete account of who someone is.
Ask together: Does this use treat each person as someone whose experience matters?
Listening
Listening means trying to understand someone's experience before preparing an answer. People who use a service, work with it, or are judged by it may notice problems its designers miss.
Invite people to describe what happened in their own words. Repeat back what you understood and let them correct it. A quiet person or a complaint that is hard to measure may still reveal something important.
Ask together: Whose experience have we not heard yet?
