GARCIA-DIAZ, F. Javier et al. Validity of Braden and EMINA's scales for patients at home, include in the immobilized patients programmee. Gerokomos [online]. 2015, vol.26, n.4, pp.150-156. ISSN 1134-928X.

Aim: Verifying Braden and EMINA's validity and select quantitative cut-off points to diferentiate Ulcer by Pressure threat in home-care patients. Method: group monitor progress and longitudinal examination of a cohort of patients during 6 months, evaluating three times, once every two months. Scope of application: Health Care Administration Este Málaga-Axarquía and Serranía, Málaga. Subject of study: Immobilized Programme patients without UPP. Resources: Authors' questionnaire including among others: demographic data, hospital admission date, Braden and EMINA scales. Sample: 353 patients, simple random sampling. Result: The original scales support internal consistency with alpha superior to 0.7. Establishing new cut-off points discriminating patients with or without UPP threat, resulting sensitivity of 61%-89% and specificity 64%-70%. The classified scales have a precission as a diagnostic method equal or superior to 65%. OR are significant, indicating existing differences under threat of UPP according to new cut-off points. Cut-off points' selected resulted in: High sensitivity threat ≤10% ≥ 95%, Braden's scale average ≤ 10, EMINA 12-15. Moderate threat 10%, <Sensitivity <83%, 64% <Specificity, <95 Braden scale average 11-15, EMINA 7-11. Minimum threat 83%, ≤ Sensitivity 100%, 0% Specificity ≤ 64%, Braden 16-22, EMINA 1-6. Non-existent threat sensitivity 100%, Specificity 0%, Braden 23, EMINA 0. Conclusion: Braden obtained a major consistency than EMINA in home-care patients. Existing a high interrelationship among both scales variables; threat being measured in similar ways. Both scales provide positive authenticity reasons in similar way, considering them equally as methods for threat diagnosis. Cut-off points established in this study are esteemed to discriminate among home-care patients with or without an ulcer: Braden 15 and EMINA 7.
