Design and setting
This cross-sectional study was conducted at healthcare facilitiesin Kurdistan Province located in the west of Iran accommodating 10 townsin 2018 [16] (Figure 1).The sampling method was census and 805 existing healthcare facilities were included in this study.
Collecting data instrument
The checklist used in this study was developed based on Hospital Safety Index (HSI) instrument. World Health Organization (WHO) has established the HSI, which is a validated, international, multi-risk assessment instrument [17]. The checklist was first introduced for hospital safety assessment by PAHO in 2008[18]. To translate and adopt HSI in Iran, in the first step, a multidisciplinary group of experts translated the checklist into Farsi. Then, four professionals in related fields of medical sciences and engineering reviewed the Persian version of the checklist in terms of application and appropriateness indicators. They also checked the accuracy of the translation. Then the compiled version was piloted in one of the hospitals in Tehran, capital of Iran. Also, content validity, content and weighting of indicators were assessed in the panel of experts and the face validity was assessed using views of the hospital personnel [19,20]. moreover, its reliability was found to be acceptable with the score of 0.82 using Cronbach's alpha coefficient [21].
The Iranian version of HSI was similar in structure of the tool and number of items to the original HIS version [19]. HSI has already been adopted for applying in the healthcare facilities with the purpose of safety assessment and was confirmed by other specialists as the collection data instrument [22]. HSI has also been used to assess the disaster safety in primary healthcare facilities around the world [23, 24].
In addition; We assessed the suitability of the checklist by an expert panel. Members of the panel were defined as individuals who were health in disasters and emergencies professionals with academic backgrounds working in primary healthcare system. We asked the experts to answer some questions regarding the suitability of the checklist for assessing healthcare facilities as well. The professionals affirmed the suitability of the checklist for assessing the healthcare facilities. This checklist has the capacity for measuring the disaster safety assessment in health facilities via recognizing threatening hazards, assessing the functional preparedness as well as structural, non-structural and total safety assessment.The checklist does not ask any question requiring confidential answers.In case of missing data one of the members of the research team contacted the person, who had completed the checklist in the relevant facility.
The section of hazard recognition included 55 questions in five sub-sectionsincluding geological, climatic, social, biological, technological and man-made hazards.Also, the probability of risk occurrencewas categorizedto fourlevels: improbable, low,moderateand high. We assigned scores of 0 or < 1, 1, 2 and 3 to each category, respectively.
The section of functional preparedness included 241 questions in 34 sub-sections. Some of these sub-sectionswere as follows: organization and structure, preparedness programs, risk assessment, insurance, risk reduction measures, firefighting, and exercise. Preparedness level was categorized to threelevels: acceptable,moderateand unacceptable. We assigned scores of 3, 2 and 1 to each category, respectively.
The section of non-structural safety includedtwo sub-sections: general with 44 questions and technical with 110 questions. In the general sub-section, the safety of general equipment found typically in most offices is measured,while in the technical sub-section, the safety of specialized equipment of health facilities was measured. The safety level of non-structural components was categorized to threelevels: safety rules have not been observed (low safety), safety rules have been partially observed (moderate safety), and safety rules have been fully observed (high safety). We assigned scores of 0, 1 and 2 to each category, respectively.
The section of structural safety includes five questions and scoring of this section is as the same as non-structural section.
In each primary healthcare facility,one health staff was assigned for the assessmentcoordination, data collection and data entry and reporting to researchteam. This person was usually the health in disaster management expert or a person in charge of health who was also responsible for providing health management in disasters or emergencies. These health staff completed basic disaster risk management courses and were responsible for health management in disasters and emergencies at their primary health care facility.these health staff, at different levels of health system had been trained about safety, risk and disaster concepts, data collection methods including field investigation, observation and interview, and scoring of checklists during two courses. Each course was organized in three days. The participants were monitored and evaluated at the end of second course by research team. During the survey period, two members of the research team were available during working hours to answerqueries from the data collection team.The data collection process started simultaneously in all primary healthcare facilities in Kurdistan province from May 2018 and finished in August 2018.
Data analysis
The completed checklists of each facilitieswere entered to the Excel software. The score of each section was calculated from 0 to 100scale and in order to homogenize the results, the score of all questions was considered from 0 to 100.Total safety score was the average scores of assessed sections in functional, structural, and non-structural areas calculated from 0 to 100. each section of the safety was classified to three safety classes according to their total score: low (≤34.0), average (34.01-66.0) and high (>66.0).
