Occupational nursing during disasters from the perspective of holistic theory.

Disasters are defined as unpredictable and complex situations. This theoretical-reflective study, conducted from August 2020 to December 2020, reflected on occupational nursing during disasters in light of Myra Levine's holistic theory. The first principle of her model is to conserve human energy, focusing on vital sign measurement; the second, conservation of structural integrity, focuses on multiple injuries; the third, conservation of personal integrity, focuses on relationships; while the fourth, conservation of social integrity, involves public and private dimensions beyond an individual level. Levine's conservation model is of special utility in disaster situations, since it is rooted in occupational nursing care, working toward effective adaptation of nursing processes for individuals and families, aiming to achieve professional autonomy and quality care for patients, their families, and society.
