Volume 7, Issue 3 (Iranian Journal of Ergonomics 2019)
Abstract

Background and Objectives: Human errors in dialysis care can cause injury and death. One of the basic steps to increase reliability in this critical process is to analyze the error and identify the weaknesses of doing this process.
Methods: The present study is a descriptive-analytic cross-sectional study. The SPAR-H method was used to identify and evaluate the probability of human error in the dialysis process. The hospital had six dialysis department and 16 dialysis machines with two nurses in each department. Data collection was done by observing the dialysis process, interview with nurses, reviewing the documents, methods of work and work instructions.
Results: The present study showed that the probability of human error in the duties of a dialysis nurse is in the range of 0.02-0.44 (except for devices related to disorder), which is related to sub-duty preparing patient as lowest rate and sub-duty of the pump set-off as highest error rate.
Conclusion: To reduce and control the human error in nursing duties in the dialysis department, control measures should be done such as increasing the number of personnel, changing the time shift of nurses, and training, preparing and revising the instructions.


Identifying the Ergonomic Components of Firefighter Gloves: Findings from a Qualitative Study

Volume 14, Issue 3 (Iranian Journal of Ergonomics-In Press 2026)
Abstract
Background and Objective: Firefighting gloves are essential personal protective equipment (PPE); however, protection alone does not ensure their effectiveness. Ergonomic characteristics, including hand fit, preservation of manual dexterity and tactile sensitivity, comfort, and ease of use, can influence firefighters’ performance and safety. This study aimed to identify the ergonomic components of firefighting gloves from the users’ perspective.
Methods: This qualitative study employed conventional content analysis with an inductive approach and was conducted from February to May 2026. Twenty active-duty firefighters were purposively recruited, five of whom had additional expertise and experience in occupational safety and personal protective equipment. Sampling continued until data saturation was reached. Data were collected through 20 semi-structured interviews and 2 focus group discussions and were subsequently transcribed, coded, and analyzed. The Lincoln and Guba criteria were applied to ensure the trustworthiness of the findings.
Results: Of 839 initial codes, 394 final codes were derived and organized into five main categories and 10 subcategories: biomechanical and musculoskeletal strain, anthropometric and dimensional fit factors, physiological factors, manual and perceptual performance, and usability and compatibility. Key components included increased grip force and localized pressure, poor dimensional fit, restricted joint mobility, heat retention and sweating, skin irritation, reduced tactile sensitivity and dexterity, difficulty in donning and doffing, and incompatibility with other protective equipment.
Conclusion: The ergonomics of firefighting gloves is a multidimensional concept encompassing biomechanical, anthropometric, physiological, manual-performance, and usability dimensions. These findings may provide a basis for developing and validating objective ergonomic indicators and for considering their incorporation into future standards. Further studies using objective measurements and including female firefighters are recommended to validate the identified components.
