FERNANDEZ LOPEZ, María Teresa et al. Incidence of hypophosphatemia in not critically ill patients with enteral feeding. Nutr. Hosp. [online]. 2017, vol.34, n.4, pp.761-766. ISSN 1699-5198.  https://dx.doi.org/10.20960/nh.615.

Background: Up to 30-40% of the patients starting artificial nutritional support develop hypophosphatemia. In general, patients with mild and moderate hypophosphatemia do not have symptoms, but severe hypophosphatemia is the hallmark of refeeding syndrome. Aim: To determine the incidence of hypophosphatemia in not critically ill patients receiving enteral feeding. Material and methods: Prospective study. We assessed during seven days 181 not critically ill patients started on enteral artificial nutrition support during seven days. Results: 51.9% of the patients were considered to be at risk of developing refeeding syndrome (United Kingdom National Institute for Health and Clinical Excellence criteria). The incidence of hypophosphatemia was 31.5%, but only 1.1% of the patients developed severe hypophosphatemia. Older age and lower plasma proteins were significantly associated with hypophosphatemia. Conclusion: The incidence of severe hypophosphatemia in our study is low, so we can't offer robust conclusions about the risk of hypophosphatemia in the type of patients receiving enteral nutrition.
