A fuzzy TOPSIS-based approach for prioritizing low-impact development methods in high-density residential areas.

The study successfully implemented six low-impact development (LID) methods to manage surface runoff in urban areas: green roof, infiltration trench, bio retention cell, rain barrel, green roof combined with infiltration trench, and rain barrel combined with bio-retention cell. Each method has unique benefits in mitigating surface runoff effects in urban environments. The following four indicators were used to evaluate the methods: runoff volume reduction, peak runoff flow rate reduction, economic sustainability, and social sustainability. The study, which lasted approximately 4 months, was conducted in an eastern Tehran metropolis residential area with a mix of old and new buildings. The SWMM model determined runoff volume and peak flow values, and a price analysis list determined the economic index. Local experts completed 25 questionnaires to evaluate the social index. Fuzzy TOPSIS multi-indicator decision criteria were used to prioritize LID methods, and the Rain barrel + Bio retention cell combined scenario emerged as the best option based on all four criteria. The method reduced peak runoff flow by 23.1-66.1% under rainfall with 10-year return periods. The green roof + infiltration trench method had the highest percentage reduction of 2,737 m3, while the infiltration trench had the lowest reduction of 273 m3.

The Prerequisites of Executing the Accreditation Program for Primary Healthcare: A Systematic Review and Meta-Synthesis.

Background: In Iran, the primary healthcare system is the front-line for society's encounter with healthcare. Health planners aim to enhance quality and administer an accreditation program. This study examined program administration prerequisites through systematic review and meta-synthesis. Methods: We conducted a systematic review and meta-synthesis of qualitative literature using Thomas and Hudson's framework. Peer-reviewed papers were searched in Scopus, PubMed, Web of Science, Google, and Google Scholar up to 2023. Results: The search found 1308 articles, with 37 relevant ones selected for review. Data extraction included setting, participants, study design, data collection, analysis, and themes. Thirteen qualitative subthemes were identified and were categorized under three elements of the Donabedian model. Conclusion: Before implementing a plan, it is crucial to consider its executive prerequisites. Revision and trial-and-error approaches can be costly and time-consuming, potentially hindering the plan's effectiveness and diverting organizations from their primary goal, leading to failure.
