Development of a quality indicator set to measure and improve quality of ICU care for patients with traumatic brain injury.

BACKGROUND: We aimed to develop a set of quality indicators for patients with traumatic brain injury (TBI) in intensive care units (ICUs) across Europe and to explore barriers and facilitators for implementation of these quality indicators. METHODS: A preliminary list of 66 quality indicators was developed, based on current guidelines, existing practice variation, and clinical expertise in TBI management at the ICU. Eight TBI experts of the Advisory Committee preselected the quality indicators during a first Delphi round. A larger Europe-wide expert panel was recruited for the next two Delphi rounds. Quality indicator definitions were evaluated on four criteria: validity (better performance on the indicator reflects better processes of care and leads to better patient outcome), feasibility (data are available or easy to obtain), discriminability (variability in clinical practice), and actionability (professionals can act based on the indicator). Experts scored indicators on a 5-point Likert scale delivered by an electronic survey tool. RESULTS: The expert panel consisted of 50 experts from 18 countries across Europe, mostly intensivists (N = 24, 48%) and neurosurgeons (N = 7, 14%). Experts agreed on a final set of 42 indicators to assess quality of ICU care: 17 structure indicators, 16 process indicators, and 9 outcome indicators. Experts are motivated to implement this finally proposed set (N = 49, 98%) and indicated routine measurement in registries (N = 41, 82%), benchmarking (N = 42, 84%), and quality improvement programs (N = 41, 82%) as future steps. Administrative burden was indicated as the most important barrier for implementation of the indicator set (N = 48, 98%). CONCLUSIONS: This Delphi consensus study gives insight in which quality indicators have the potential to improve quality of TBI care at European ICUs. The proposed quality indicator set is recommended to be used across Europe for registry purposes to gain insight in current ICU practices and outcomes of patients with TBI. This indicator set may become an important tool to support benchmarking and quality improvement programs for patients with TBI in the future

Análise de dados gemelares: uma aventura guiada para investigadores das Ciências do Desporto Analysis of twin data: a guided tour for researchers in Sport Sciences

Este tutorial pretende apresentar, de forma sumária: 1) a importância dos estudos gemelares em Educação Física e Ciências do Desporto; 2) a estrutura básica deste tipo de delineamento; 3) as etapas da análise descritiva inicial; 4) os procedimentos de análise em grau crescente de complexidade - da análise de variância, à modelação de estruturas de covariância; 5) bem como a relevância da exploração da disocordância intra-par de gêmeos monozigóticos. Esta processologia, baseada num tutorial, recorrerá aos valores do fenótipo índice de atividade física nos tempos de lazer, com base numa amostra de 207 pares de gêmeos mono e dizigóticos. Todas as etapas da análise são comentadas e será interpretado o significado dos resultados, salientando o fato do fenótipo em causa ser explicado pelos fatores genéticos em cerca de 63%.<br>This tutorial has the following purposes: 1) to summarize the importance of twin studies in Physical Education and Sport Sciences´ research; 2) to show the basic structure of twin designs; 3) the levels of descriptive analysis; 4) the steps of growing complexity in data analysis - from analysis of variance to structural equation modeling; 5) as well as the analysis of discordant intra-pair differences of monozygotic twin data. The steps of this long list of procedures will be illustrated in this tutorial using the phenotype leisure time physical activity with data from 207 monozygotic and dizygotic twin pairs. Commentaries and explanations will be provided in all steps of the analysis, highlighting the fact that the used phenotype is genetically accounted for 63% of the total variation
