A model for doing not only medical missions, but many forms of short-term projects (partnered with a long-term ministerial presence) looks a bit like a fish (or an ICHTHUS if you prefer). It is based somewhat on the model used for CPM (Church-Planting Multiplication). The same basic principle can be utilized.

This comes from my book “Principles and Practices of for Healthy Christian Medical Missions: Seeking the Church’s Role for Effective Community Outreach in the Philippines and Beyond”
A: The idea of a medical mission comes to one person or a small group, and there is the decision to attempt to move forward with the idea.
B. This is the team-building phase. Buy-in is developed within the community and with outside help. Partnerships are developed and plans are worked out.
C. Others are told about the mission. The community is invited and the outside team supporters are told and encouraged to pray and help in tangible ways. Eventually a maximum number of people are involved as the entire community (ideally) is involved or invited, and the outside team is sent off.
D. This describes those involved in the medical missions. This number is smaller because not everyone who is invited actually comes. In the Philippines approximately half to 2/3s of those invited actually come (at least in rural areas).
E. This describes those who respond to the Gospel based on assent. In some cultures, this assent is to the Gospel (expressed perhaps in saying the “sinner’s prayer,”) In some cultures, such as the Philippines, this sort of response may be made without any real conviction. As such it may not be the most useful guide for follow-up. However, it is important to keep records of all who attended and all who made this decision.
F. It is also useful to find a narrower filtering of those who come. This may be with a desire for Bible Study, or for home visitation. In the Philippines, for example, many will express an interest to “pray to receive Christ” as a way of expressing gratitude for the medical care provided. However, there is no such feeling of debt to agree to a Bible Study (for example) so it is often a better guide for community spiritual response.
G. After the medical mission, the hosts can do follow-up. They would probably start with Group F as priority, then to Group E, and finally Group D. However, in all likelihood those who actually act on their spoken decision will be smaller than the other groups. So for example, in the case of a Bible Study, one may have hundreds attend the medical mission, with dozens responding in faith, and perhaps 2 or 3 dozen desiring a Bible study. Of these, perhaps 10 or 15 actually respond. These can be put into 1 Bible study, or perhaps 2 growth groups, or maybe a handful of accountability groups.
H. It is from the core group G that growth will occur with multiplication of small groups, or development of house churches, or creation of a church, or whatever.
