TL;DR: The NMDS-AT was found to be feasible: needed data was available in the analysed patient records, data extraction showed good reliability, and typical analysis could be performed and showed interesting results.
Abstract: Background: An Austrian Nursing Minimum Data Set (NMDS-AT) has been developed to describe the diversity of patient populations and variability of nursing care based on nursing diagnoses, nursing interventions, and nursing outcomes. The aim of this study is to test the feasibility of using this NMDS-AT by assessing the availability of data needed for the NMDS-AT in routine nursing documentation, and to assess its reliability and usefulness. Methods: Data were collected in a general hospital from patient records of 20 patients representing 457 patient days. Availability of needed data was assessed by two raters in a chart review based on an NMDS-AT form. The interrater reliability (n=20) and intrarater reliability (n=5) was assessed using Cohen’s kappa coefficient and intraclass correlation coefficient (ICC). Usefulness was assessed by verifying whether typical analysis questions can be answered by the documented NMDS-AT data. Results: In the 20 patient records, thirteen nursing diagnoses, 50 nursing interventions, and five nursing outcomes occurred, representing 68 (58.6 %) of the overall 116 data elements of the NMDS-AT. The data were found at different data sources (e.g., electronic nursing record or paper-based fever chart) and in various forms (e.g., standardized or free text). The interrater reliability of the thirteen nursing diagnoses showed kappa values (percentage of agreement) ranging from 0.35 (85 %) to 1.00 (100 %). The 50 nursing interventions showed ICCs ranging from 0.03 to 1.00. All nursing outcomes showed an ICC of 1.00. The intrarater reliability showed 100 % agreement. Performing typical analysis questions showed that the extracted NMDS-AT data are able to answer questions of clinical management, of policy makers, and of nursing science. Conclusions: The NMDS-AT was found to be feasible: needed data was available in the analysed patient records, data extraction showed good reliability, and typical analysis could be performed and showed interesting results. Before the NMDS-AT can be introduced in healthcare institutions, the following challenges need to be addressed: 1. improve the quality of nursing documentation; 2. reduce fragmentation of documentation; 3. use a standardized nursing classification system; and 4. establish mappings between nursing classification systems and the NMDS-AT.

TL;DR: The mobile application may be considered a valid and reliable tool to assess thoracolumbar ROM for both asymptomatic and chronic low back pain subjects and intrarater reliability of individuals with and without back pain is verified.
Abstract: Background Smartphone devices have been used to measure range of motion (ROM) in different joints. Objective To verify the concurrent validity of thoracolumbar ROM using a mobile application and a digital inclinometer, as well as the intrarater reliability of individuals with and without back pain. Methods One investigator was responsible for measuring the ROM during the evaluations performed on 20 asymptomatic subjects and 20 symptomatic subjects in two consecutive days. Results Regarding to the concurrent validity, the Intraclass Correlation Coefficients (ICC) were classified as very good for all analyzed movements. For intrarater reliability, the mobile application had ICC varying between good and very good for the symptomatic subjects and very good for asymptomatic subjects. Conclusions The mobile application may be considered a valid and reliable tool to assess thoracolumbar ROM for both asymptomatic and chronic low back pain subjects.

TL;DR: The proposed method is based on structural reliability techniques and accounts for both statistical and failure effect correlations and is assumed that failure of any component is due to increasing damage (fatigue phenomena) and the component lifetimes follow some continuous and non-negative cumulative distribution functions.
Abstract: Estimation of system reliability by classical system reliability methods generally assumes that the components are statistically independent, thus limiting its applicability in many practical situations. A method is proposed for estimation of the system reliability with dependent components, where the leading failure mechanism(s) is described by physics of failure model(s). The proposed method is based on structural reliability techniques and accounts for both statistical and failure effect correlations. It is assumed that failure of any component is due to increasing damage (fatigue phenomena) and the component lifetimes follow some continuous and non-negative cumulative distribution functions. An illustrative example utilizing the proposed method is provided, where damage is modeled by a fracture mechanics approach with correlated components and a failure assessment diagram is applied for failure identification. Application of the proposed method can be found in many real world systems.

TL;DR: In this article, the authors propose a method to solve the problem of "uniformity" and "unweighting" of the problem: "uncertainty" is introduced.
