For the last three decades, research on Information Technology Business Value (ITBV) has highlighted how organizations can create greater value from IT investments in different industries, including the healthcare sector. There has been some research investigating the business value of Health Information Systems (HIS). However, the current body of knowledge regarding the challenges in front of proper business value realization of these systems is limited. This study investigates the challenges of HIS business value creation using a combination of the Fuzzy Analytic Hierarchy Process (FAHP) and fuzzy Decision-making Trial and Evaluation Laboratory (DEMATEL). First, this study reviews the literature to identify the main challenges in the field. The outcome of this step revealed three main categories and 22 challenges, including technological (ten challenges), organizational (eight challenges), and environmental (four challenges). Then, this study first uses FAHP to evaluate the weighting for each criterion and then adopts the fuzzy DEMATEL method to establish contextual relationships among those criteria. We find out that technological challenges are the most crucial dimension. Moreover, we observed that “infrastructure costs” has the highest priority. Under the technological dimension, “maintenance costs” and “systems compatibility” challenges are the most critical since they are in the cause area and directly influence the HIS outcomes. Under the organizational dimension, “Change in strategic objectives” is the most important challenge. Moreover, “inter-departmental coordination”, “training costs”, “proficiency”, and “users’ knowledge” are affected by each other as well as influenced by the net causes. The outcome of this study shows that to handle HIS business value creation challenges, healthcare executives should start with infrastructure costs, maintenance costs, and systems compatibility challenges.

Hail is an atmospheric rainfall with a complex mechanism. The Greeks were among the pioneers of knowledge in ancient times and they termed “hail” as “frozen rain” (Anaximander) and “instant freezing of water and moisture” (Aristotle, n.d.). These two meanings are inconsistent with current scientific facts. The Noble Qurʼan is the most authentic text to encourage Muslim believers to think about creation and strengthen their faith in the eternal power of the Creator. For instance, the mechanism of hail falling has been expressed in the verse (Q.24:43) with specific and gradual indications. In this research, first, by library method, different explanations of this verse were obtained from valid interpretive sources and then, the scientific findings of meteorologists and climatologists on hail were extracted from reference scientific texts on atmospheric sciences. In the third stage and based on comparative method, the scientific rules were placed next to interpretations to test the novelty and degree of the allusions of this verse. We found that the stages of hail falling included:“invisible water vapor rises from the sea,” “water vapor ascends into the atmosphere,” “reaching the condensation stage,” “cloud formation,” “convergence of ascending currents,” “formation of cumulonimbus cloud,” “growth of hailstones during successive ascents and descents by adsorption and freezing of ice needles,” and finally “their fall down over ground” respectively. Meanwhile, the steps in the Noble Qurʼan are mentioned in verse (Q.24:43) in the following order:“clouds movement slowly,” “clouds convergence,” “clouds accumulation,” “the formation of mountain-like clouds,” and “hail falling from the clouds.” The results also showed that likening cumulonimbus cloud in the verse (Q.24:43) to “mountain” have four respects that were beyond the comprehension of the people at the time of the revelation of the Qurʼan. Nowadays, these features are known to stationary and satellite meteorological instruments. These four characteristics are “cloud layer temperature,” “their constituent phase,” “troughs and ridges inside the cloud” and “cloud height up to the tropopause.” Based on these four characteristics, the Noble Qurʼan considered the cloud of cumulonimbus as similar as “mountains.” Meteorologists divide any cumulonimbus cloud into three floors, including cold at the bottom, super-cold at the top and intermediate in the middle. We find these three floors in the same way in the high mountains. These floors are the current rivers (liquid phase), snow and ice reserves (solid phase) and in the middle region a combination of two liquid and solid phases, namely water and ice. Images from the cumulonimbus from above the atmosphere show dark and deep valleys and light and raised ridges. The fourth feature is to be said, none of the surface phenomena are as high as the mountains. Finally, meteorological findings show that it is the only cumulonimbus that rises from the ground to a height of 12,000 meters and more.
