Pressure ulcers (PU) may increase the incidence of hospital complications, and one should prevent this damage. The Braden Scale stands out as a tool to assess the risk of PU. The study aimed to identify changes in the score of the Braden subscales are associated with the risk of developing PCU. Logistic regression was used in a retrospective cohort study conducted in Hospital de Clínicas de Por...

BACKGROUND A rule-based system, the Braden Scale based Automated Risk Assessment Tool (BART), was developed to assess risk for pressure ulcer in a previous study. However, the BART illustrated two major areas in need of improvement, which were: 1) the enhancement of decision rules and 2) validation of generalizability to increase performance of BART. OBJECTIVES To enhance decision rules and v...

BACKGROUND Patients in intensive care units are at higher risk for development of pressure ulcers than other patients. In order to prevent pressure ulcers from developing in intensive care patients, risk for development of pressure ulcers must be assessed accurately. OBJECTIVES To evaluate the predictive validity of the Braden scale for assessing risk for development of pressure ulcers in int...

The Braden Scale for Pressure Sore Risk(©) is a screening tool to determine overall risk of pressure ulcer development and estimate severity of specific risk factors for individual residents. Nurses often use the Braden nutrition subscale to screen nursing home (NH) residents for nutritional risk, and then recommend a more comprehensive nutritional assessment as indicated. Secondary data analys...

Using resolutions of singularities introduced by Cortez and a method for calculating Kazhdan-Lusztig polynomials due to Polo, we prove the conjecture of Billey and Braden characterizing permutations w with KazhdanLusztig polynomial Pid,w(q) = 1 + q for some h. Résumé. On démontre la conjecture de Billey et Braden sur les permutations w pour lesquelles le polynôme de Kazhdan-Lusztig Pid,w(q) = 1...

STUDY DESIGN  Prospective cohort study. CLINICAL QUESTION  Does the patients' body mass index (BMI) influence the degree of intraoperative lumbar lordosis in patients undergoing operative treatment on the Mizuho Orthopedic Systems Incorporated (OSI) Jackson spinal table? METHODS  Twenty-four consecutive patients undergoing posterior spinal instrumentation and fusion on the Jackson table, ex...

Consider a modified, stable, two node Jackson network where server 2 helps server 1 when server 2 is idle. The probability of a large deviation of the number of customers at node one can be calculated using the flat boundary theory of Schwartz and Weiss [Large Deviations Performance Analysis (1994), Chapman and Hall, New York]. Surprisingly, however, these calculations show that the proportion ...

The Jackson Development Methods are JSP (Jackson Structured Programming) and JSD (Jackson System Development). JSP is a method for designing programs as compositions of sequential processes; JSD is a method for specifying and designing systems whose application domain has a strong temporal flavour and contains objects whose behaviour is describable in terms of sequences of events. Many program ...

OBJECTIVE Estimating the incidence rate of pressure ulcers and verifying factors associated with this occurrence in a cohort of hospitalized patients. METHOD This is a cohort study in which the considered outcome was the time until pressure ulcer occurrence. Estimated effect of the variables on the cumulative incidence ratio of the outcome was performed using the Cox proportional hazards mode...
