A substantial body of evidence supports the beneficial health impact of an increase in primary care physicians for underserved populations. However, given that in many countries primary care physician shortages persist, what options are available to distribute physicians and how can these be seen from an ethical perspective? A literature review was performed on the topic of primary care physician distribution. An ethical discussion of conceivable options for decision makers that applied prominent theories of ethics was held. Examples of distributing primary care physicians were categorised into five levels depending upon levels of incentive or coercion. When analysing these options through theories of ethics, contrasting, and even controversial, moral issues were identified. However, the different morally salient criteria identified are of prima facie value for decision makers. The discussion provides clear criteria for decision makers to consider when addressing primary care physician shortages. Yet, decision makers will still need to assess specific situations by these criteria to ensure that any decisions they make are morally justifiable.
