What forms of rationing exist in health care? Distinguish implicit from explicit, and hard from soft rationing.

Question

Accepted Answer

Implicit rationing happens through capacity shortages (e.g. long waiting times) without an open decision; explicit rationing is an open rule, such as excluding a service from the benefits catalogue. Hard explicit rationing reflects an absolute shortage (donor organs); soft explicit rationing limits reimbursement (dentures).
Rationing already exists and is practised:

Form
Mechanism
Example

Implicit
capacity-related scarcity that is structural and therefore politically intended
long waits for certain specialists; limited intensive-care beds

Explicit: benefit exclusion
service removed from the catalogue or capped
travel vaccinations, glasses frames, massages

Explicit, hard
absolute scarcity; no amount of money helps
transplant medicine: too few donor organs

Explicit, soft
social insurance reimburses only part
dentures

Rationing always presupposes, even if unspoken, a prioritisation: a ranking of indications, procedures or patient groups (next card).
