Validation of the National Institutes of Health Stroke Scale, Modified Rankin Scale and Barthel Index in Brazil: The Role of Cultural Adaptation and Structured Interviewing

Background: We aimed to validate three widely used scales in stroke research in a multiethnic Brazilian population. Methods: The National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS) and Barthel Index (BI) were translated, culturally adapted and applied by two independent investigators. The mRS was applied with or without a previously validated structured interview. Interobserver agreement (kappa statistics) and intraclass correlation coefficients were calculated. Results: 84 patients underwent mRS (56 with and 28 without a structured interview), 57 BI and 62 NIHSS scoring. Intraclass correlation coefficient was 0.902 for NIHSS and 0.967 for BI. For BI, interobserver agreement was good (kappa = 0.70). For mRS, the structured interview improved interobserver agreement (kappa = 0.34 without a structured interview; 0.75 with a structured interview). Conclusion: The NIHSS, BI and mRS show good validity when translated and culturally adapted. Using a structured interview for the mRS improves interobserver concordance rates. Copyright (C) 2008 S.

Determinants of death following burn injury

Background: Burn care has changed considerably. Early surgery, nutritional support, improved resuscitation and novel skin replacement techniques are now well established. The aim of the study was to establish whether changes in management have improved survival following burn injury and to determine the contributory factors leading to non-survival. Methods: This was a retrospective outcome analysis of data collected from a consecutive series of 4094 patients with burns admitted to a tertiary referral, metropolitan teaching hospital between 1972 and 1996, Results: The overall mortality rate was 3.6 per cent. This decreased from 5.3 per cent (1972-1980) to 3.4 per cent (1993-1996) (P = 0.076). The risk of death was increased with increasing burn size (relative risk (RR) 95.90 (95 per cent confidence interval 12.60-729.47) if more than 35 per cent of the total body surface area was burned; P < 0.001) increasing age (RR 7.32 (3.08-17.42) if aged more than 48 years; P < 0.001), inhalation injury (RR 3.61 (2.39-5.47); P < 0.001) and female sex (RR 1.82 (1.23-2.69); P = 0.003). Operative intervention (RR 0.11 (0.06-0.21); P < 0.001) and the presence of an upper limb burn (RR 0.53 (0.35-0.79); P = 0.002) decreased the risk. Conclusion: Modern burn care has decreased the mortality rate. Increasing burn size, increasing age, inhalation injury and female sex increased, while operative intervention and an upper limb burn decreased, the risk of death.

The social construction of PETE in higher education: Toward a research agenda

The focus of this paper is the social construction of physical education teacher education (PETE) and its fate within the broader process of curriculum change in the physical activity field. Our task is to map the dimensions of a research program centered on the social construction of the physical activity field and PETE in higher education. Debates in the pages of Quest and elsewhere over the past two decades have highlighted not only the contentious nature of PETE practices and structures but also that PETE is changing. This paper offers one way of making sense of the ongoing process of contestation and struggle through the presentation of a theoretical framework. This framework, primarily drawing upon the work of Lave and Wenger (1991) and Bernstein (1990, 1996), is described before it is used to study the social construction of PETE in Australia. We assess the progress that has been made in developing this research program, and the questions already evident for further developments of a program of study of the physical activity field in higher education.

Determinants of nurses' intention to administer opioids for pain relief

A statewide cross-sectional survey was conducted in Australia to identify the determinants of registered nurses' intention to administer opioids to patients with pain. Attitudes, subjective norms and perceived control, the key determinants of the Theory of Planned Behavior, were found to independently predict nurses' intention to administer opioids to these patients. Perceived control was the strongest predictor. Nurses reported positive overall attitudes towards opioids and their use in pain management. However, many negative attitudes were identified; for example, administering the least amount of opioid and encouraging patients to have non-opioids rather than opioids for pain relief. The findings related to specific attitudes and normative pressures provide insight into registered nurses' management of pain for hospitalized patients and the direction for educational interventions to improve registered nurses' administration of opioids for pain management.
