Background and Aim: Job enrichment is a method that has been used to increase employee satisfaction and work motivation. The Hackman and Oldham job characteristics model (1976) has served as the foundation for many job enrichment efforts. In particular, a considerable amount of research has been devoted to the study of the job characteristics-job satisfaction relations. Te purpose of this study was to statistically determine the relation between job characteristics and job satisfaction among employees of hospitals affiliated to Tehran University of Medical Sciences (TUMS) in 2007.
Materials and Methods: This study was a cross-sectional one, including 6 TUMS-affiliated hospitals-Emam, Shariati, Baharlo, Ziaeian, Madaen and Azadi. The sample size was 400, consisting of 200 administrative employees (50%), 151 nurses (38%) and 49 physicians (12%). The random sampling and stratified proportional sampling methods were used to select the hospitals and interviewees, respectively. Two questionnaires were developed and used to identify job characteristics and job satisfaction: 1) job diagnostics surveys (JDS) and 2) Hertzberg's job satisfaction questionnaire. The reliability of the questionnaires was ascertained by test-retest using the Pearson correlation coefficient (r = 0.88). Linear-by-linear association and ordinal logistics regression analysis were used for analyzing the data gathered.
Results:The relations between the Motivational Potential Score (MPS) and job characteristics (except for feedback) with job satisfaction were statistically significant (p<0.05). Task identity was the most effective determinant of job satisfaction.
Conclusion: It appears that all the job characteristics (except feedback) are important determinants of job satisfaction of the hospital employees. Although the work environment is in need of restructuring, it is important to note, from a positive perspective, that the job characteristics discussed in this study are readily amenable to change job satisfaction at the organizational level.

Background and Aim: The aim of this study was to assess the adherence to anti-retroviral prophylaxis after occupational and non-occupational exposure to human immunodeficiency virus (HIV) in patients consulting the Voluntary Counseling and Testing Center (VCT) of Imam Khomeini Hospital, Tehran during the period 2008 to 2009.

Materials and Methods: In this prospective study, patients were selected, the required information about them was recorded, and adherence to anti-retroviral drugs (including Ziduvudin, Lamivudin and Efavirens) was determined based on self-report by the patients. Eighty-nine exposed patients were followed monthly for 4 months, and in the case of low-adherence (less than 95%) they were asked for the reason(s) for noncompliance.

Results: Of the 89 patients, 55 were men (61.8%) and 34 (38/2%) were women with a mean age of 30.16± 8.39 years 47 participants (52.8%) were single and 42 (47.1%) married 27 subjects (30.3%) were physicians, 35 (39.3%) nurses and 27 (30.3%) had occupations outside the healthcare system. From among the 36 subjects (40.5%) who stopped the treatment, 24 (27.0%) stopped it correctly (that is, when the serological test proved to be negative), while 12 (13.4%) did not stop it on a sound basis. Fifty-three subjects (59.6%) completed the prophylaxis. Adherence was found to be significantly associated with age and marital status (p<0.05).

Conclusion: The main reason for stopping the prophylaxis (a negative serological test result of the resource patient) was more pronounced than previous studies, which indicates the higher availability of the resource patient.

  Background and Aim : The National Malaria Control Program was developed, in 2011, into the National Malaria Surveillance Program. It is one of the most comprehensive surveillance systems in Iran. The aim of this study was to evaluate the impact of malaria elimination program on data quality and accuracy in the national malaria surveillance system.

  Materials and Methods : This was a cross-sectional study conducted in four malaria-prone provinces in Iran to determine and assess the completeness and accuracy of the information collected in the malaria surveillance system. The purpose was to compare data reporting forms 3 and 4 (reporting positive cases from selected district health centers) between two time points, namely, 2009-2010 (before starting the program) and 2010-2012 (after starting the program).

  Results: The total number of reporting forms included in the study was 1927, nearly 54% from the initial time point and the rest from the final time point. The highest and lowest proportions were 94.78% and 17.30% from Iranshahr and Hormozgan University health centers, respectively. On the whole, the degree of completeness of the forms was 84% (83.7% and 85% before and after starting the program, respectively). Based on the Chi-square test, the differences were not statistically significant.

  Conclusion: Only a minor change occurred in the degree of completeness of the forms between the two time points: a 4% increase in form 4 and a 3% decrease in form 3. It can be concluded, then, that the elimination program h ad no significant effect on the completeness and accuracy of the reporting forms.
