Waiting time is one of the factors affecting patients' satisfaction with the quality of services, therefore, reducing the waiting time has an essential role in the improvement of services and clients' satisfaction. The present study was performed to study the client patients waiting time in referral restorative dentistry department of dental clinic using Six Sigma model.

In this descriptive study, 300 patients who referred to the restorative dentistry department of dental clinic, were included. Finally, 30 subjects were selected using random sampling method. Data were collected by waiting time measurement forms and researcher-made checklists. To determine the process quality, six sigma model was used. Finally, data were analyzed using SPSS version 16.

The highest mean waiting time belonged to the oral diseases department (mean=31 min) and the lowest one belonged to the examination unit of restorative dentistry department (mean=15 min). The most important factors extending the waiting time were simultaneous entrance of patients (mean=4.6 min), lack of medical students' skill and experience (mean=4.2 min), lack of employees and integration of reception unit with cash desk (mean=4 min), respectively.  

Therefore, by analyzing reception process, appropriate management, and using Six Sigma model, waiting time will reduce, clients' satisfaction will increase, and the quality of services will improve.

The provision of healthcare services is one of the main and vital necessities of every society, the lack of which is considered as a weak point for governments and leads to extensive social discontent. Regarding the increasing treatment costs, it seems essential to find a way to decrease the patient's expenses.
This practical study was conducted in the Shahid Arefian Hospital of Urmia city, Iran based on the five phases of Lean Six Sigma. Out of the factors affecting patient's cost reduction, the cancellation of elective surgeries was investigated by the implementation of brainstorming meetings.
According to the results, the principal factors of surgery cancellations increasing patient's costs were paraclinic, clinical, and system factors, as well as the factors related to the surgeon and patient. The implementation of Six Sigma phases revealed that the sigma of the present process was 3.1827 that is an undesirable value for a medical center since disorganization in this section is not compensable.
In the brainstorming meetings held with the members involved in the project, the practical solutions of reducing the canceling factors were proposed and presented in two flowcharts. It is predicted that the implementation of the proposed solutions would upgrade the sigma of the process to 3.5.

Sharp rise in health care costs associated with the reduction of hospital's support by government has increased the importance of insurance organizations as the main source of hospital's income. An important part of hospitals’ demands is related to the medical records of Iranian Health Insurance organization that are subject to deductions and are deduced from the hospitals’ demands after investigating the cause of defect in the process.
The present study was conducted as a retrospective descriptive research. In this study, sampling was not conducted and all incomplete files of patients covered by Iranian Health Insurance Organization in the reference hospital (n=30) were entered into the study. Data of checklists were entered into Excel software version 22 and the causes were determined by using Fishbone diagram. Six-sigma scale was used to analyze the quality of the process.
Process errors were detected in 6 groups and the highest error rates were respectively related to pharmaceutical orders control stages, entering them in cards and requesting drug through drug delivering system. The quality of the reviewed process was evaluated as moderate level based on the calculated sigma. The highest rate of error was related to the records of patients covered by rural fund of non-global services.
Measures such as staff training, monitoring and updating the record keeping system and improving external parts coordination can greatly reduce errors in three above-mentioned stages.

In the present competitive era, organizations need to use a suitable model such as supply chain management in order to earn and keep a suitable place in the national arena and gain competitive advantage. The aim of this study was to analyze the quality of logistics supply chain process in a teaching hospital of Kerman.
This is a qualitative research, in which the phenomenological approach was used. Data were collected through semi-structured interviews with the personnel of the Procurement Unit who were selected purposively and a random review of 20 product request forms. Finally, data were analyzed using framework analysis, and the process quality was analyzed using the six sigma scale.
Errors identified in the supply chain included 9 main themes and 29 subthemes among which, inadequate monitoring of the accuracy of the product request forms, inattention to the point of ordering, purchase regardless of the quality, inappropriate archive, inappropriate selection of supplier, and non-compliance with standard time of purchase and delivery of goods were the main errors identified. The quality of supply chain process according to Six Sigma scale was moderate.
Weakness in the information system of the procurement unit and lack of suitable relationship between this unit and other units of the hospital lead to incidence of errors in the supply chain process that can be significantly reduced through implementing an office automation system and electronic procurement system.

Application of six sigma in library management provides quality services to the users by which the satisfaction of users can be achieved with the help of providing better and improved new services in the libraryThis research aimed to investigate the Observance amount components of Six Sigma in Medical Sciences Library, University of Tehran, Shiraz, Isfahan from the perspective of librarian.

This was a descriptive- analytical survey in which a questionnaire was used for data collection. The study population consisted of 210 librarians of Tehran, Shiraz and Isfahan University of Medical Sciences Bachelor's degree or higher in librarianship in 2012-2013. 147 questionnaires were returned.

Organizational culture would be considered as an effective factor in organizational performance such as six sigma. So the purpose of this paper was to determine effective organization’s cultural factors on the implication of six sigma in teaching hospitals affiliated with Kerman University of Medical Sciences (KUMS). aterials and This Study was done in the way of descriptive case study. The research society consisted of the employees of KUMS (N=1634). The sample size was 110 that were selected through a stratified random sampling. The data was collected via a self-report questionnaire. Data gathering Instrument was a questionnaire which had three parts (demographic information, organizational culture and six sigma). The five-point likert scale was used to score the questions. At the end, data was analyzed by multi-variable Regression test. The paper finds that the highest mean of organizational culture indexes in the hospitals were related to organizational identity (mean 3.43) and the lowest index (2.47) was related to differences and contradictions. To imply six sigma in the hospital, the highest mean was related to focus on patients (2.42) and the lowest (2.34) to improve their religious ability and failure tolerance. Robbie's organizational culture model as independent variable predict 69 percentage of variance in implementation of six sigma as dependent variable (p≤0.001,F(10,41)=9/238, R2=0.693)Management support (p=0/015,t=2/538, β=0/457) and risk taking (p=0/002,t=2/381, β=0/255) effected implementation of six sigma in the hospitals expensively. It is argued that Robbie's organizational culture model more importantly affected on the implementation of six sigma especially support management and risk taking so researches suggest building productivity incubator in the hospitals.

Abstract Intrudaction: Conspicuous achievements of organization with minimum facilities on one hand and failure of organizations with materialist abilities on the other hand have been shown the considerable role of factors including non-materialist and spiritual in their success. Organizational culture would be considered as an effective factor in organization performance. correlation of organization's culture with the implication of six sigma in teaching hospitals affiliated with Kerman University of Medical Sciences (KUMS). This is a descriptive-correlative study. The research society were employees of KUMS (N=1634). The sample size was 110; selected through a stratified random sampling. The data was collected via researcher-made self-administered questionnaires. Data collection tool was a questionnaire with three parts: (demographic information, organizational culture, and six sigma). The five point Likert scale used for scoring questions. Our findings showed that there is a significant correlation between organizational culture and six sigma (Pearson correlations coefficient found as follow: 0.772, (0.01).In comparing organizational culture indices; control and individual creativity had the highest mean score (61.37 and 58.94, respectively).Among six sigma indices, genuine focus on the customer, and Data- and Fact-Driven management had the highest mean score (2.92 and 2.82 respectively). Strive for perfection, tolerate failure had the lowest mean score.(2.34) Considering the significant correlation between organizational culture and implication six sigma under, it would be desirable to prepare an appropriate atmosphere for implication six sigma in hospitals.

Abstract Health Care organizations, because of their special nature of Medical Services, impossibility of assessment by customers, and increasing of patients and customer expectation, have to apply different management approach. In recent decade Six Sigma has been considered as systematic and powerful to improve service quality and cost saving. Six Sigma is a statistical and systematic approach that tends to define the process performance defects and decrease the clinical and business processes errors that are done with wasting time, high costs and poor outcomes. The aim of this paper is to investigate the role of Six Sigma on the improvement of quality services in Health Care Organizations using library and internet resources, and descriptive and analytical methods. Literature review: Empirical Results in different countries that have through implemented Six Sigma in Health Care Organizations have improved the time cycle and patient cycle in emergency room, operating room, radiology and laboratory services, supportive management, antibiotics treatment, improvement in scheduling hospital staff activities, medical errors and cost saving. Also, good infrastructure and continual training is a must to six sigma implementation. Six Sigma methodologies provide a systematic approach to improvement business processes based on customer demand and actual analysis in carrying out processes in any organization. There is a major difference between Six Sigma and other approaches and that is why it is being used in Health care organizations. Nevertheless the different methods used to implement whatever approach the basic ground to embrace the culture quality should exist in the organization, Also quality improvement is a continuum process which derives the cooperation of all working teams and the use of appropriate means and methods in solving individual problem. Although, the use of any method needs to preparation and adaptation of quality culture in organizations. Also quality improvement is continuum process that needs to cooperate and interaction among work teams and use of suitable tools and methods for any problem.
