In healthcare institution management, hospital flow control and the prediction of overcrowding are major issues. The objective of the present study is to develop a dynamic scheduling protocol that minimizes interference between scheduled and unscheduled patients arriving at the emergency department (ED) while taking account of disturbances that occur in the ED on a daily basis. The ultimate goal is to improve the quality of care and reduce waiting times via a two-phase scheduling approach. In the first phase, we used a genetic algorithm (based on a three-dimensional cubic chromosome) to manage scheduled patients. In the second phase, we took account of the dynamic, uncertain nature of the ED environment (the arrival of unscheduled patients) by continuously updating the schedule.

Abstract Better understanding of the lead curvature, movement and their spatial distribution may be beneficial in developing lead testing methods, guiding implantations and improving life expectancy of implanted leads. Objective The aim of this two-phase study was to develop and test a novel biplane cine-fluoroscopy-based method to evaluate input parameters for bending stress in leads based on their in vivo 3D motion using precisely determined spatial distributions of lead curvatures. Potential tensile, compressive or torque forces were not subjects of this study. Methods A method to measure lead curvature and curvature evolution was initially tested in a phantom study. In the second phase using this model 51 patients with implanted ICD leads were included. A biplane cine-fluoroscopy recording of the intracardiac region of the lead was performed. The lead centerline and its motion were reconstructed in 3D and used to define lead curvature and curvature changes. The maximum absolute curvature Cmax during a cardiac cycle, the maximum curvature amplitude Camp and the maximum curvature Cmax@amp at the location of Camp were calculated. These parameters can be used to characterize fatigue stress in a lead under cyclical bending. Results The medians of Camp and Cmax@amp were 0.18 cm−1 and 0.42 cm−1, respectively. The median location of Cmax was in the atrium whereas the median location of Camp occurred close to where the transit through the tricuspid valve can be assumed. Increased curvatures were found for higher slack grades. Conclusion Our results suggest that reconstruction of 3D ICD lead motion is feasible using biplane cine-fluoroscopy. Lead curvatures can be computed with high accuracy and the results can be implemented to improve lead design and testing.

BACKGROUND: Standardization of documentation has enabled the use of medical records as a primary tool for evaluating health care functions and obtaining appropriate credit points for medical centres. However, previous studies have shown that the quality of medical records in emergency departments is unsatisfactory.AIM: The aim of this study was improving the nursing care documentation in an emergency department, in Iran.MATERIAL AND METHODS: This collaborative action research study was carried out in two phases to improve nursing care documentation in cooperation with individuals involved in the process, from February 2015 to December 2017 in an affiliated academic hospital in Iran. The first phase featured virtual training, an educational workshop, and improvements to the hospital information system. The second phase involved the recruitment of human resources, the implementation of continuous codified training, the establishment of an appropriate reward and penalty system, and the review of patient education forms.RESULTS: The interventions improved nursing documentation quality score of 73.20%, which was the highest accreditation ranking provided by Iran’s Ministry of Health and Medical Education in 2017. In other words, this study caused a 32% improvement in the quality of nursing care documentation in the hospital.CONCLUSION: The appropriate practices for improving nursing care documentation are employee participation, managerial accountability, nurses’ adherence to documentation standards, improved leadership style, and continuous monitoring and control.

Introduction: Patient satisfaction is an essential component of effective delivery of quality care in the emergency department (ED). Frequent reflection on current practices is required to detect areas in need of improvement. The Ontario Hospital Association (OHA) outlined five ‘Leading Practices’ (LPs) targeted to increase patient satisfaction in this setting. The ED volunteers are a group of individuals who have unique perspectives on ED practices that are unbiased by confounders affecting patients and staff. The goal of this study was to explore the unique perspectives of ED volunteers involving what they believe will improve the delivery of patient-centered care, as well as to examine to what extent Saskatoon EDs are embracing the principles outlined in the OHA LPs. Methods: A two-phase mixed methods approach, with a survey followed by interviews that allowed participants to expand on survey findings was used. The pool of 45 ED volunteers was extended the opportunity to participate resulting in 36 survey responses and 6 interviews. The 13 Likert-grade survey questions were generated to align to each of the LPs and allowed room for qualitative feedback. Interview questions were generated following 15 survey responses to expand on the LPs that were rated below average. Results: Analysis of responses identified inefficient ED processes leading to increased waiting times, inefficient patient location, inadequate signage, a lack of physical space, unclean environments, and a lack of staff and volunteer awareness regarding spiritual care and interpreter services, perceptions of received care by patients due to long wait times and level of cultural safety training of ED staff. Themes reduced from interviews yielded common themes such as patient frustration, disorganization, uncomfortable environment, overcrowding, prolonged wait times, and patient misconception of ED processes at Site 1. Themes common to Site 2 included organization, patient-friendly environment, patient misconception of ED processes, and prolonged wait times. Additionally, the volunteers suggested a plethora of interventions that could improve the current processes in Saskatoon's EDs to make them more patient friendly. Conclusion: Saskatoon EDs comply reasonably well to the OHA Leading practices. Surveying ED volunteers provides important insight into current practices and areas for improvement, and should be considered at other sites to improve adherence to the OHA LPs.

Objective: To describe a two-phase study of the structure of Australasian psychiatrist peer review groups. Method (Phase one): Initially, information was sought from chairskoordinators of psychiatrist peer review groups regarding the nature and organisation of their group. Results (Phase one): One hundred and three questionnaires were returned describing a number of models of peer review. Three principal models were identified: a teaching hospital model, a private practice model, and a private institution model. Method (Phase two): The second-phase questionnaire sought information on the quality of the review, using six proposed standards developed by the Quality Assurance Committee of the Royal Australian and New Zealand College of Psychiatrists. Results (Phase two): Many groups indicated that four of the proposed standards (those relating to documentation, having clear goals, reviewing actual clinical cases, and rigorous protection of confidentiality) were either already being followed or would be relatively easy to implement. The remaining two proposed standards (including structure, process and outcome dimensions of health care in the case discussion, and the use of explicit criteria) presented more difficulty. Conclusion: The application of such standards to peer review group meetings should assist groups to provide a forum for presentation and evaluation of clinical work where participants know they will be challenged in an environment which is both supportive and educational.

The staking of containers on ideal locations within the yard is a tactical decision that affects the productivity of container terminals. The goal is to improve posterior loading and retrieval operations, to get better use of terminal resources. In this paper, we study how to allocate storage space for outbound containers in container terminals. A two-phase methodological framework is proposed. The first phase groups outbound containers into clusters of similar operational loading conditions. Then in a second phase, a bi-objective storage space assignment model is solved to determine the set of block-bays where groups of similar containers will be stored during the planning horizon. This study presents a double contribution. On one hand, it proposes a new methodological framework that combines operations research and data mining techniques to solve a storage space assignment problem for outbound containers. On the other hand, it analyzes the impact of three factors on four performance metrics used to evaluate the quality and quantity of alternative solutions to the problem of allocation of storage space for outbound containers. The experimental framework is composed of an experimental design study to assess the impact of three factors on four performance metrics used to assess the quality of the storage space assignment solutions, and a case study to validate the proposed approach. The experimental results reveal that the storage yard's capacity and the number of clusters used to group the containers destined to a vessel are the main factors that affect the number and quality of alternative solutions.

Quality management is an approach to management which requires establishing quality policies, procedures and practices on regular basis. Engineering education is a process of developing techno human resources, which are to be used later as input to industry which in turn produces goods and services for the societal use. Having considered the current situation of the engineering educational system and the quality of all its individual components it can be noticed that the awareness of the importance of education as a foundation for the growth and development of the country, such as India, is not strong enough. Engineering graduates passing out from educational institutions have to fulfill modern and high standard requirements that are needed by industry. Therefore, there is a greater need to instill quality in engineering education to produce technically skilled and creative man-power in India. The continuous assessment of quality is of paramount importance for educational institution. Education efficiency and success does not depend just on quantity but as well on quality. This paper has discussed key points for the improvement in the quality of engineering education with a case study undertaken at various engineering colleges in India. The study was conducted in two phase; first phase is the critical investigation of the literature and the second phase is a study on the quality of engineering education provided by the educational institutions in Visakhapatnam city. A simple random sampling technique was adopted for the study. A research study described in this paper identifies and analyses the quality of engineering education at the educational institutions which adopt the total quality management system to increase the quality and meet the industrial requirements and then suggests some ingredients to improve the quality.
