Safety culture assessment: A fuzzy model for improving safety performance in a radioactive installation

Constructs of leading indicators: A synthesis of safety literature

INTRODUCTION

Leading indicators represent an invaluable tool that offer organizations the capability to: track health and safety performance, not just failures and accidents; measure effectiveness of safety efforts adopted; and focus on undesired precursors, rather than undesired occurred events. Despite these palpable advantages associated with their adoption, leading indicator's definition, application, and function are mostly ambiguous and inconsistent within literature. Therefore, this study systematically reviews pertinent literature to identify the constructs of leading indicators and generates guidance for leading indicator implementation (as a conceptual model).

METHOD

The overarching epistemological design adopted interpretivism and critical realism philosophical stances together with inductive reasoning to analyze 80 articles retrieved from the Scopus database, plus 13 more publications supplemented by the snowballing technique. Analysis of the safety discourse within literature (as secondary data) was undertaken in two stages, namely: (1) a cross-componential analysis identified the main features of leading indicators in comparison to lagging indicators; and (2) content analysis revealed prominent constructs of leading indicators.

RESULTS AND CONCLUSION

Analysis results identify that the definition, types, and development methods represent the main constructs for understanding the concept of leading indicators. The study identifies that ambiguity around the definition and function of leading indicators is due to the lack of differentiation of its types, namely passive leading indicators and active leading indicators.

PRACTICAL APPLICATION

As a practical contribution, the conceptual model, which introduces continuous learning through a perpetual loop of development and application of leading indicators, will help adopters create a knowledge repository of leading indicators and to continuously learn and improve their safety and safety performance. Specifically, the work clarifies their difference in terms of the timeframe passive leading indicators and active leading indicators take to measure different safety aspects, the functions they serve, the target they measure and their stage of development.

Ergonomics management model based on good practices of large industrial companies: Structured elements through the fuzzy set theory

BACKGROUND

Most organizations perceive the concept of ergonomic actions as a local tool used to improve workplace issues. Ergonomics however is not included in global management systems. The paradigm of ergonomics action in large organizations proposed by this study is that of management systems whose primary objective is the pressing need for continuous performance improvement, acquisition of excellence, and integration into all aspects of the business.

OBJECTIVE

The general objective of this work is to draw a frame presenting a model of ergonomics management based on good practices in managing this discipline in large industrial companies.

METHOD

In this study, we describe a strategy based on the fuzzy set theory to aggregate a group of good practices expressed by experienced ergonomists attached to large industrial companies for handling the lack of ergonomics in an organization.

RESULTS

A set of good practices was compiled as a basis for application in ergonomics in large companies.

CONCLUSION

This study shows that ergonomics should not be considered an isolated phenomenon but in a strategic, proactive, integrated, and perennial way as one of the management subjects.

The Safer Culture Framework: An Application to Healthcare Based on a Multi-Industry Review of Safety Culture Literature

BACKGROUND

Errors and preventable harm to patients remain regrettably common and expensive in healthcare. Improvement requires transforming the culture of the healthcare industry to put a greater emphasis on safety. Safety culture involves holding collective attitudes, values, and behaviors that prioritize safety. The Safer Culture framework, previously established through a narrative review of literature in multiple industries, provides a consensus on what impacts safety culture, how it manifests in behavior, and how it influences safety-related outcomes.

METHODS

Through a theoretical review, we validate, refine, and provide nuance to this framework for the development of safety culture in healthcare contexts. To accomplish this, we conceptually map existing dimensions pulled through the literature onto our Safer Culture framework.

RESULTS

A total of 360 articles were reviewed. We present specific elements for each dimension in our framework and apply the dimension to healthcare contexts.

CONCLUSION

We provide an evidence-based and comprehensive framework that can be used by patient safety leaders and researchers to guide the evaluation of safety culture and develop interventions to foster patient safety culture and improve patient safety outcomes.

Impact of Safety Culture on Safety Performance; Mediating Role of Psychosocial Hazard: An Integrated Modelling Approach

We conceptualize that safety culture (SC) has a positive impact on employee’s safety performance by reducing their psychosocial hazards. A higher level of safety culture environment reduces psychosocial hazards by improving employee’s performance toward safety concerns. The purpose of this study was to evaluate how psychosocial hazard mediates the relationship between safety culture and safety performance. Data were collected from 380 production employees in three states of Malaysia from the upstream oil and gas sector. Structural equation modeling was implemented to test the suggested hypotheses. The proposed model was evaluated using structural equation modeling. A stratified sampling with a Likert 5-point scale was used to distribute the questionnaires. Furthermore, the proposed model was tested using the simulation of the structural equation and partial. According to our findings, all hypotheses were significant. A review of prior studies was used to select the items of the dimension for the data collection. Safety culture was assessed with psychosocial hazard to determine its direct and indirect impact on safety performance. Results suggest that to enhance safety performance (leading and lagging), psychosocial concerns in the workplace environments should be taken into consideration by employees. In addition, the findings showed that the psychosocial hazard fully mediates the relationship between safety culture and safety performance.

Determining the safety culture in a gun factory in Turkey: A fuzzy approach

Safety culture is a very complex phenomenon due to its intangible nature. It is tough to measure and express it with numerical values, as there is no simple indicator to measure it. This paper presents a fuzzy inference system that measures the safety culture. First of all, a safety culture assessment questionnaire is developed by utilizing related literature. The initial questionnaire had 29 items. The questionnaire is applied to 259 employees within the gun manufacturing factory. After making an exploratory factor analysis, the questionnaire is based on five factors with 25 items. The safety culture indicators are defined as; safety follow-up audit reporting, employees’ self-awareness, operational safety commitment, management’s safety commitment, safety orientedness. Normality, reliability, and correlation analysis are performed. Then a fuzzy model is constructed with five inputs and one output. The inputs are the five factors mentioned above, and the output generated is the safety culture result, which is between 0-1. The presented fuzzy model produces reliable results indicating the safety culture level from the employees’ eyes. Beyond exploring the employees’ safety culture, the proposed model can easily be understood by the practitioners from various sectors. Furthermore, the model is straightforward to customize for various fields of industry.
