The general goal of the management of communication and information technology (MCIT) in the health sector, is to accelerate collecting, achieving and supporting the health system processes, and effective decision-making for managing this system;because preparing and providing health care services for society is very complex, and highly dependent on the information system. The aim of this investigation is to determine the mean scores of the possibility of implementing the MCIT standards in Khorasan Razavi hospitals, from the perspective of managers. This was a cross sectional descriptive-analytic study conducted in two steps in all hospitals. In the first step, the applicability of the standards in hospitals was studied. In the second step, the current status of hospitals was compared with international standards MCIT. In order to determine the validity of the questionnaires, opinions of professors and experts were acquired. Regarding the reliability, the SPSS V. 12 calculated the value of Cronbach’s to be 0.95 for the first questionnaire and 0.86 for the second questionnaire. Data were analyzed using statistic tests of one way ANOVA and t-test. The level of significance was fixed at 0.5. In the 16 hospitals studied, the mean and standard deviation of MCIT were (57.25 ± 13.74). The MCIT standards are applicable in hospitals of Khorasan Razavi according to half (49.4%) of managers;nonetheless, their application requires greater efforts by the hospitals.

The purpose of this study was to investigate the dimensions and conditions caused by shifts in nurses who worked in constant shifts in non-governmental selective hospitals in Tehran in 2014. In this cross-sectional and applied research, the shifts standard questionnaire was used. After confirming the validity and reliability (Cronbach’s alpha 0.73), the questionnaires were distributed among 305 nurses of 6 non-governmental selective hospitals in Tehran, based on stratified random sampling. In the research, the data analysis was conducted in two levels of descriptive and inferential statistics. The response rate was 0.91. 74.4% of the participant nurses were female and 25.6% were male. The results showed that there was a significant relationship between age and physical health (P = 0.008), gender and physical health (P = 0.015), education and health (P = 0.014), gender and physical-cognitive anxiety (P = 0.006), age and social-familial status (P = 0.001), Marital status and social-familial status (P = 0.001), having a second job and social-familial status (P = 0.001), education and sleep-fatigue (P = 0.002). Planning with respect to standards of nurses’ working hours and avoiding overtime, especially nurses who have more experience, can prevent severe complications of shifts and improve health level and ultimately the quality of care.
