[Designing nursing work scheduler intelligent system based on genetic algorithm]

Adjustment of nursing scheduling for specific periods of time to meet the needs of hospitals, nurses and patients is a time-consuming and challenging task for nursing managers. The aim of this study was to design a nursing scheduler system based on genetic algorithm to render better services to patients and overcome traditional scheduling problems. In this applied research, we designed software based on the data derived from interviews with the personnel of two pediatric wards. We transformed the expert entity planning procedure to mathematic function using Genetic Algorithm Programming and create the schedule. We compared the system-designed schedule with the schedule that was written by experts in MATLAB software. The results showed that the system-designed schedule resulted in 57% reduction in the arrangement costs and 93% time saving for nursing managers in comparison with the expert-designed schedule during 6 months. System-designed schedule had higher efficiency than the expert-designed one. It entailed higher efficiency of managers and higher job satisfaction of nurses. It also reduced problems of working with paper schedules. Nurses' preferences and hospital requirements could be taking into account, as well. Since we used the limited data gathered from two selected wards for writing the program, the program should be modified based on the data provided from other wards. Further studies are needed to design similar systems with more details in order that it can be available in various wards of hospitals

Prevalence and characteristics of irritable bowel syndrome [IBS] amongst medical students of Gilan northern province of Iran

Irritable bowel syndrome [IBS] is one of the most prevalent gastrointestinal disorders characterized by non-specific symptoms such as abdominal pain and altered bowel habits with no known organic pathology. Its prevalence varies in different communities. We performed this study to determine the prevalence of IBS in medical students who attended Gilan University of Medical Sciences [GUMS]. Medical students of GUMS were studying during 2002 academic year were enrolled in this cross-sectional study. Within a specifically designed schedule, trained general practitioners performed student interviews. The interviewers used a structured questionnaire based on the Rome II criteria. Data were analyzed using SPSS-10 software. Results were presented as percentages and the mean +/- SD and level of significance was denoted as a p-value <0.05. This study included 422 students, 148 [35.1%] males and 274 [64.9%] females, trained in various educational levels at GUMS whose mean age was 23.7 +/- 2.9 years. The prevalence of IBS was 12.6% [53 of 422]. IBS was more prevalent in females than males [15% [41 of 274] vs. 8.1% [12 of 148]; p<0.05]. Reported a Physician 37.7% of cases visit in comparsion to 17.6% of non IBS case [p<0.05]. This study shows a higher prevalence of IBS in medical students than in other sections of the Iranian population. A prevalence of 12.6% in medical students, who are in an active phase of life, requires careful planning to provide alleviation

Irritable bowel syndrome [IBS] prevalence in medical students of Gilan university of medical sciences

Irritable bowel syndrome [IBS] is one of the most prevalent gastrointestinal disorders, characterized by non-specific symptoms such as abdominal pain and altered bowel habit without any organic pathology. Its prevalence varies in human communities. We performed this study to determine the prevalence of IBS in medical students of Gilan University of Medical Sciences [GUMS]. Medical students of GUMS in 2002 enrolled in this cross-sectional study. Under a schedule they were interviewed by trained general practitioners with structured questionnaire, which based on Rome II criteria. Data was analyzed by SPSS-10 software. Results were presented into percentage and mean +/- SD. Level of significance was denoted as p value less than 0.05. This study included 422 students training in various educational levels of GUMS, 148 [35.1%] males and 274 [64.9%] females whose mean age was 23.7 +/- 2.9 years. Prevalence of IBS was 12.6% [53 of 422 with 95%, CI 9.5%-16.1%]. IBS was more prevalent in females than males [15% [41 of 274] vs. 8.1% [12 of 148]] [p<0.05]. This study shows higher IBS prevalence in medical students than other published Iranian reports. Prevalence of 12.6% in students, who are in active phase of life, necessitates planning to help this population
