Current risk screening mechanisms are often subjective and could be improved. Aims: To evaluate whether a biochemical assessment tool (Prognostic Inflammatory and Nutritional Index; PINI) based on measurement of albumin, α1-acid glycoprotein, C-reactive protein, and prealbumin is of value in estimating the prognosis of patients with pressure ulcers of European Pressure Ulcer Advisory Panel grade 1 and above. Methods: Serum samples were collected from patients participating in a clinical trial of a pressure ulcer preventing mattress. These were analysed for the markers listed above and the PINI calculated. PINI was then evaluated against patient outcome. Results: A statistically significant difference between PINI values in patients whose pressure ulcers improved and those whose ulcers worsened was found in parametric testing, but significance was not achieved in non-parametric testing. A receiver operating characteristic plot showed the PINI was superior to chance in estimating prognosis. Conclusions: The PINI appears to offer a potential route to improving pressure ulcer risk estimation and thus allocation of scarce equipment to improve prevention. %U https://jcp.bmj.com/content/jclinpath/59/3/308.full.pdf
