Semantic field:

The words ^care^, ^therapy^, ^treatment^, and ^intervention^ overlap in a semantic field, and thus they can be synonymous depending on context. Moving rightward through that order, the connotative level of holism decreases and the level of specificity (to concrete instances) increases. Thus, in health care contexts (where its senses are always noncount), the word ^care^ tends to imply a broad idea of everything done to protect or improve someone's health (for example, as in the terms ^preventive care^ and ^primary care^, which connote ongoing action), although it sometimes implies a narrower idea (for example, in the simplest cases of wound care or postanesthesia care, a few particular steps are sufficient, and the patients's interaction with that provider is soon finished).

In contrast, the word ^intervention^ tends to be specific and concrete, and thus the word is often countable; for example, one instance of cardiac catheterization is one intervention performed, and coronary care (noncount) can require a series of interventions (count). At the extreme, the piling on of such countable interventions amounts to interventionism, a flawed model of care lacking holistic circumspection─merely treating discrete problems (in billable increments) rather than maintaining health.

^Therapy^ and ^treatment^, in the middle of the semantic field, can connote either the holism of ^care^ or the discreteness of ^intervention^, with context conveying the intent in each use. Accordingly, they can be used in both noncount and count senses (for example, ^therapy^ for chronic kidney disease can involve several dialysis treatment per week).

The words ^aceology^ and ^iamatology^ are obscure and obsolete synonyms referring to the study of therapies.
