The allocation of healthcare resources takes place at two distinct levels. At the macroeconomic level, policymakers decide on budgets, staffing, cost-effectiveness thresholds, clinical guidelines and insurance payments; at the microeconomic level, healthcare professionals decide on whom to treat, what the appropriate treatment is, how much time and effort should each patient receive and how urgent the need for care is. At both levels, there is a constant social need for just allocation. Policymakers are mostly guided by abstract principles of justice, thinking in terms of groups of patients, epidemiological data, impersonal statistics and economic costs. On the other hand, healthcare professionals understand the need for justice at a more personal level, as they interact with patients and, in a sense, put theory into practice. Nurses hold a unique position in healthcare systems, as, traditionally, they are closer to patients than other health professionals. This means that they have a firsthand view of the effect that their decisions have on specific patients and, therefore, nurses tend to get more influenced by their personal feelings, values and beliefs at the microeconomic level. This presentation shall examine the gap between abstract macroeconomic and concrete microeconomic health resources allocation decisions, with a particular emphasis on the role of the nurse.
