Hospital wastes contain a wide range of microorganisms and require special management due to their dangerous properties, and their improper disposal is considered a serious threat to the environment and public health. Therefore, the purpose of the present study was to determine and influence the educational intervention based on the theory of planned behavior on the behaviors of employees in the waste management of Hafez Hospital of Shiraz, Iran.

The present interval study was conducted in 2018 on all healthcare personnel (170 people) and service workers (32 people) of Hafez hospital of Shiraz, Iran. The statistical population of the present study was completed by enumeration. The measurement tool in the present study was a questionnaire based on the theory of planned behavior and knowledge assessment which its validity and reliability were estimated and used by experts. Other tools included a waste management evaluation checklist which included management infrastructure, separation, collection, transportation, temporary storage, disposal, and weighing form of hospital wastes. The present study was conducted in two stages before and after the educational intervention. In the first stage, before the educational intervention, information was collected through questionnaires, a waste management evaluation checklist, and waste weighing continuously for a week. Then the educational content was designed. Two months after the educational intervention, in the second stage, the health care and service workers completed the questionnaires once more. Moreover, the checklist was completed and the waste was weighed over again. Obtained data were analyzed using SPSS software version 22 and parametric (paired t-test) and non-parametric (Wilcoxon) tests.

The findings indicated a significant difference in the mean score of knowledge, attitude, subjective norms, perceived behavioral control, and behavioral intention among both group health care workers and service workers after the intervention (P<0.001). After educational interventions, a significant difference in normal waste per capita was found (P<0.05). No significant difference was observed in infectious waste, sharp waste, and pharmaceutical chemical waste per capita(P≥0.005). There was a significant difference in waste management in terms of separation, collection, transportation, and disposal (P<0.001). The infrastructure management and temporary maintenance were the same before and after the educational intervention.

The findings of the present study indicated that educational interventions based on the theory of planned behavior are effective in raising the awareness of health care and service workers and improving hospital waste management. Furthermore, the use of educational strategies and appropriate educational content can increase the quality of educational interventions.

The concentration of aerosols in the atmosphere has increased in recent years. These particles can adversely affect human health. Studies show that indoor air quality is affected by outdoor air. Moreover، people spend a significant portion of their time indoors، and few studies have been done in this area. Therefore، the purpose of this study was to measure the concentration of outdoor and indoor suspended particles in Hafez Hospital، Shiraz، Iran، and determine the relationship between these parameters. A cross-sectional study was done in Hafez Educational Hospital in Shiraz from October to November 2011. Sampling was done twice a week. The outdoor and indoor air sampling was conducted in each ward of the hospital. 144 samples were collected for analysis; including 24 samples for each ward of the hospital and also for outdoor air. Sampling was performed by using a sampler Aerosol Mass Monitor (Model GT-331، Japan) to measure the particle concentrations of PM10 and PM2. 5. To compare the concentration of indoor suspended particles in different wards of the hospital with outdoor particles، one-way ANOVA was used. Then، the data were analyzed using SPSS version 11. 5. The results obtained were compared with 24-hour particulate matter concentrations of EPA and WHO guidelines. Results showed that indoor and outdoor air quality of the hospital in terms of air quality index for PM2. 5 is in a good condition. The air quality index for PM10 for the indoor air showed that 95. 2% of wards were in good condition، and two obstetric wards were in average condition. Status of outdoor air quality for PM10 is unhealthy for sensitive groups in 75% of samples. To assess the relationship between suspended particles in outdoor and indoor air of hospital wards، Pearson correlation was used. Accordingly a significant relationship was observed in PM10 and PM2. 5 of outdoor and indoor air of a number of hospital wards (P > 0. 05). The average ratio of PM10 and PM2. 5 of indoor to outdoor air (I/O) were، respectively، 1. 41 and 6. 10، which indicated the low ventilation and air exchange within the wards. The results also showed that there is a significant relationship between the concentration of suspended particles in the indoor air and outdoor air. This represented a penetration of outdoor particles into the indoor air of hospital wards. Thus، for hospitals that are located in high traffic areas، utilizing appropriate ventilation systems within the hospital is effective in reducing air pollution.
