Urban Density and Vertical Complexity in High-Rise Women’s Hospitals: Development and Validation of the HRWHPI for Hot-Arid Cities
This study develops and validates the High-Rise Women's Hospital Performance Index (HRWHPI), a rigorous, evidence-governed framework for hot-arid cities that utilizes expert consensus to establish critical safety gates and weighted indicators, ultimately demonstrating its capacity to prevent unsupported scoring when essential project evidence is unavailable.

Imagine a city where the land is so precious that the only way to build a hospital is to build it upward, stacking floors of care high above the ground. This is not just a matter of stacking rooms; it changes how a hospital works. In a tall building, the movement of patients, staff, and supplies becomes a complex vertical journey. If the elevators fail, if the fire escapes are blocked, or if the power goes out, the consequences are immediate and severe. This is especially true for a women's hospital, where the design must also protect the privacy of mothers, support the delicate needs of newborns, and ensure that families can stay close without compromising safety. When you add the intense heat of a hot, dry climate to this mix, the challenge grows even larger. The building must keep its occupants cool and safe while managing the unique risks of a high-rise medical facility.
For a long time, experts have studied these pieces separately. Some looked at how to evacuate a tall building, others at how to design a birthing room, and others at how to keep a hospital cool in the desert. But there was no single tool that brought all these needs together. There was no way to check if a specific high-rise women's hospital in a hot climate was actually safe and ready to open, especially when the detailed technical plans were hidden or missing. Without a clear method, a building might be judged as "passing" simply because the people checking it didn't have access to the critical documents proving it was safe. This gap meant that important safety questions could go unanswered, or worse, be answered incorrectly.
To solve this, a researcher named Ibrahim Ahmed Adam Ahmed developed a new way to measure these complex buildings, called the High-Rise Women's Hospital Performance Index. Think of this index as a very strict, detailed checklist designed specifically for tall hospitals in hot, dry cities. It does not just ask if a building looks good or has enough space; it asks if the building can survive a fire, if the elevators can move patients safely, if the air is clean enough to prevent infection, and if the power and water systems will keep working when things go wrong. The checklist is built on 72 specific points, organized into nine different areas of concern. Some of these points are absolute deal-breakers. If a building fails even one of these critical safety checks, it cannot be considered safe, no matter how good it is at everything else.
The researcher did not create this list in a vacuum. He gathered a group of 17 experts from different fields, including architects, engineers, and medical planners, to review every single item on the list. These experts agreed that the list was clear, relevant, and measurable. They confirmed that the 27 most critical safety items were indeed non-negotiable. They also helped decide how much weight to give each part of the building. For instance, they determined that the systems for power, water, and medical gases were the most important, followed closely by how the building is constructed and tested before opening. This process ensured that the final tool reflected the real-world priorities of building a safe hospital, rather than just a theoretical ideal.
Once the checklist was locked in place, the researcher tested it to see if two different people would get the same result when using it. They gave the same set of information to two independent reviewers and asked them to score the building. The reviewers agreed on the vast majority of the scores, and they agreed perfectly on the most critical safety items. This proved that the tool was reliable and could be used by different people to get the same answer. However, the real test came when the researcher tried to use this new index on a real, existing project: a high-rise women's hospital in Riyadh, Saudi Arabia.
Here is where the story takes a surprising turn. The researcher tried to apply the 72-point checklist to the Riyadh hospital using only the documents that were publicly available. He found that for most of the checklist, there was simply no information. While he could see the general layout of the building and some details about the site, the crucial technical documents were missing. He could not see the detailed plans for the fire safety systems, the specific engineering designs for the elevators, or the records proving that the building's systems had been tested and worked correctly. Because the index requires proof before it can give a score, and because the critical safety items could not be verified, the researcher could not give the building a pass or fail grade.
The result was that the entire score for the hospital was withheld. This was not a failure of the building, nor was it a failure of the index. Instead, it was a success of the index's design. The tool was built to prevent a dangerous mistake: giving a building a passing grade just because the people checking it didn't have the right papers. By refusing to guess or assume, the index highlighted exactly what was missing. It showed that while the building might look fine on the surface, there was no evidence to prove it was safe in the ways that mattered most. The researcher confirmed that even if he changed the importance of different parts of the checklist, the result would have been the same: without the evidence, no score could be given.
This study demonstrates that building a safe hospital in a high-rise, hot-climate city requires more than just good intentions or a nice design. It requires a rigorous, evidence-based approach that can distinguish between what is known and what is unknown. The new index provides a structured way to do this, ensuring that safety claims are backed by real proof. It acts as a gatekeeper, stopping the process if the necessary evidence is not there. In a world where hospitals are getting taller and cities are getting denser, this kind of clarity is essential. It ensures that when a building is declared safe, that declaration is based on facts, not on missing information.
