Designing an organizational memory model for reporting the medical errors

Background: The increasing growth in the volume of the data in the organizations and the resultant challenges due to medical errors during the last two decades have made the necessity of reporting and managing medical errors more apparent. Organizational memory (OM) has been known as one of the tools appropriate for implementing knowledge management. The goal of the present study is to design an organizational memory model for medical departments of the teaching and medical centers of Charmahal va Bakhtiyari province in Iran. Materials and Methods: This study is descriptive - applied in nature and its population consisted of the personnel of teachingmedical centers in Charmahal va Bakhtiyari province. Identifying the processes was performed through observation and the required data for identifying and reporting the medical errors was collected through conducting one structured interview with 65 personnel from the medical departments of 5 centers under research. OMs were derived through library research and online search. Based on the results of need-analysis and reviewing of the models, the proposed model was prepared and then was judged and evaluated by the medical professionals through Delphi test technique. Results: The personnel who took part in the study believed if they have access to the data and information required for reporting the medical errors, they will have a better performance (85). they regarded the use of organizational memory as a necessity (98) and enumerated the occurrence of errors, slowness of the work, irregularity, discontent and wonderlessness of the customers as some challenges resulting from human error and system fault (86). Discussions: Organizational memory system which relates organizational knowledge to job functions related to reporting the errors not to recognize the wrongdoer but to prevent error repetition, is one of the requirements of the medical centers which can promote the efficiency and organizational learning

A comparative study on the benefits and challenges of the application of mobile technology in health

Background: The application of mobile technology in the health domain i.e mobile health (mhealth) commonly refers to the use of mobile telecommunication and multi-media technologies for providing health services and public health systems. Some scholars consider mobile health as a subsystem of health technology which, due to the existing conditions, has become more significant compared to other interventions in this field. The present study intends to investigate the global approach on mobile health technology on the one hand, and its benefits and challenges on the other. Materials and Methods: As a comparative-descriptive study conducted in 2011, the present study has tried to explore mhealth technology strategies in public health domain, different types of mhealth interventions and benefits of using mhealth as well as its challenges and obstacles. The data were collected through informational sources such as articles, books, magazines and valid websites. Then, the status of the countries were compared and analyzed as far as the development of this technology is concened. Results:Based on the findings of the study, one of the criteria affecting the development of mhealth is the high penetration of mobile phone. By October, 2011, the estimated number of mobile users has been over 5 billion showing a penetration coefficient of 76. The review of the research on the obstacles and challenges experienced in moving towards the development of this technology by World Health Organization revealed that prioritization and increasing knowledge level are the most significant obstacles in the way to develop this technology. Discussions: Mhealth technology has been provided in most countries with the aim of promoting public health and accelerating the supply of health services. Having a penetration coefficient of over 90 in Iran, it can be predicted that this country can take effective steps towards development of this technology

Conclusions Conclusion The performance indicators of hospitals toward optimal health standards have been average

Numerical Simulation of Sub-cooled Boiling Flow with Fouling Deposited inside Channels

This document is the Accepted Manuscript version of the following article: X. Liu, X. Zhang, T. Lu, K. Mahkamov, H. Wu, and M. Mirzaeian 'Numerical simulation of sub-cooled boiling flow with fouling deposited inside channels', Applied Thermal Engineering, Vol. 203, pp. 434-442, June 2016. The version of record is available online at doi: https://doi.org/10.1016/j.applthermaleng.2016.04.041. © 2016 Elsevier Ltd. All rights reserved.In this article, a numerical simulation has been performed to investigate the sub-cooled boiling flow in axisymmetric channels using the two-phase particle model. The equivalent diameter of the channel is 4.38 mm with 365.7 cm in length. The fouling deposited layer is filled with subsequent two-thirds of the flow channel. The internal surface of the channel is covered by a fouling deposit layer with a thickness ranging from 0.225 mm to 1.55 mm. Uniform heat flux of 29267.6 W/m2 is applied on the heated wall. Validation of the CFD model is carried out through comparison with open published experimental data and a close agreement is achieved. A new parameter, Security factor, is introduced and defined in the current study. Numerical results show that the developed two-phase particle model could well predict the water-steam two-phase change flow. The Nusselt number in the fouling region without fouling deposited could be 50 times higher than that with fouling layer. The heat transfer performance of the channel with thickness of 0.225 mm fouling deposit layer is 5 times larger than that with thickness of 1.55 mm fouling deposit layer. It is also found that the inlet velocity has significant impact on the boiling and total pressure drops along the channel.Peer reviewe

The Effectiveness of Acceptance and Commitment Group Therapy on Psychological Capital in Cardiovascular Patients in Babol

BACKGROUND AND OBJECTIVE: Psychological capital is one of the positive psychological indices that is defined by the characteristics of optimism, perseverance, positive self-efficacy, and tolerance. This study was conducted to evaluate the effectiveness of acceptance and commitment group therapy on psychological capital in cardiovascular patients in Babol. METHODS: This cross-sectional study was performed among 24 cardiovascular patients who referred to governmental and non-governmental medical centers of Babol in two groups of 12 based on pretest-posttest design. The therapy based on acceptance and commitment was performed for the experimental group in 8 sessions. Participants were re-evaluated one month after the sessions, and psychological capital was evaluated according to self-efficacy, hope, tolerance and optimism subscales. FINDINGS: The results of the study showed that there was a significant difference between the subscales of the psychological capital in the experimental and control groups in tolerance (3.53±0.48 vs. 2.88±0.67) (p6.03) and optimism (40.6±0.56 vs. 2.94±0.66) (p>26.459). CONCLUSION: The present study showed that acceptance and commitment therapy could be considered as an effective intervention in increasing the psychological capital of cardiovascular patients

multi objective optimization of a solar humidification dehumidification desalination unit

In the present paper, a humidification–dehumidification desalination unit integrated with solar system is considered. In the first step mathematical model of the whole plant is represented. Next, taking into account the logical constraints, the performance of the system is optimized. On one hand it is desired to have higher energetic efficiency, while on the other hand, higher efficiency results in an increment in the required area for each subsystem which consequently leads to an increase in the total cost of the plant. In the present work, the optimum solution is achieved when the specific energy of the solar heater and also the areas of humidifier and dehumidifier are minimized. Due to the fact that considered objective functions are in conflict, conventional optimization methods are not applicable. Hence, multi objective optimization using genetic algorithm which is an efficient tool for dealing with problems with conflicting objectives has been utilized and a set of optimal solutions called Pareto front each of which is a tradeoff between the mentioned objectives is generated
