Redefining Smart Hospitals: Health Innovation through Architecture

Looking out of the room, you see rolling hills covered in verdant green. Abundant sunshine pours in through wide windows, along with the crisp scent of the countryside air. Built around an uvumuvu tree, which is the heart of the native Bureran community, the Butaro district hospital in Rwanda stands as a testament to the power of design to not just create a space for inhabitation, but for healing. 

In 2007, the Government of Rwanda, along with Partners in Health, collaborated with the MASS Design Group, a Boston-based nonprofit architectural firm, to solve the health crisis faced in the Burera district. One of the poorest districts in the country then, it had neither a hospital nor any medical staff. In a resource-constrained setting, complicated by unique local epidemiology, the team underwent multiple consultations with global health experts from T.H. Chan School of Public Health and Centers for Disease Control and Prevention (CDC). Applying principles of public health rooted in evidence-based design (EBD), a novel approach was adopted taking into account the context of the local community and culture. 

Simple, affordable interventions like the use of germicidal UV light and high-volume fans for natural ventilation proved tremendously effective in infection prevention and control. Sourcing local volcanic rock as material for construction, while employing the members of the community, went a long way in not just fostering a shared sense of ownership for the centre, but also led to building costs being invested in the local economy. Terraced gardens on the hillside enhanced biodiversity conservation. Consequently, there was a dramatic improvement in overall patient wellbeing and outcomes, with a reported 35% decrease in transmission of airborne diseases like tuberculosis. The hospital may not have been equipped with state of the art equipment and cutting-edge medical technology, but the use of a human-centred approach is what sets it apart as a “smart hospital” in the truest sense.

The Butaro District Hospital is a fascinating case study of the concept of evidence-based design (EBD), a process of employing research-backed evidence for optimal patient care and health outcomes, in addition to considerations like the budget, architect sensibilities, and local contexts. Every aspect of the healthcare environment is rigorously researched, from details enlisting physical construction, like the dimensions of windows and rooms, to the ambient features of light, noise, and ventilation, and even characteristics of interior design. For instance, patients in hospitals often report daytime sleepiness due to poor sleep quality at night. This affects their medication timings, stress levels, and healthcare experience. But by using materials with greater acoustic absorbability in the room and keeping at least one window in the room to sync their circadian cycles, this problem can be addressed. 

The role played by EBD is backed by studies in the field of environmental psychology, which outlines the role played by our natural and built environments in dictating our perceptions, emotions, and behaviors. In the context of hospitals, multiple studies enlist the role played by room design in patient outcomes. For instance, one study found that a shorter post-operation hospitalisation period and lower use of analgesics were observed in patients whose rooms overlooked green spaces as opposed to patients in similar rooms overlooking an artificial environment. Another study found that 95 percent of patients with closer contact to green spaces and nature had much lower stress levels and a greater ability to cope. Positive effects of exposure to nature even translated into the financial costs of healthcare, which were reduced by a fifth for pain management. Thus, biophilic principles, which incorporate natural elements into architecture, form an important facet of the evidence-based designing process by directly impacting health outcomes.

While keeping a patient-focused approach is vital for the successful design of any hospital, it is equally important to create a seamless working space for the staff. The Penn Pavilion is a great example demonstrating how innovation can be fostered through architectural design not just for better patient outcomes but also for enhancing the well being of staff. Erecting a life-size styrofoam mock up to run dry simulations for a better understanding of the daily processes of hospital staff, the architects applied the principles of EBD with a focus on modular design to create a hospital that sustains its utility even against future innovation. 

These concepts are not new. In the early 19th century, when there was no treatment for tuberculosis, patients were sent to sanatoria to heal in sunlight and open air. With the advent of pharmacology and the arrival of the industrial revolution, the focus shifted from healing environments to functionality, causing the gradual industrialization of the hospital ecosystem. And today, as we hone in our focus on the “smartness” of hospitals by integrating tools of automation through AI, robotics, rapid diagnostics, and complex data systems, we stand at risk of reinforcing the binary of human-centric versus technology-centric care. Maybe it is time we redefine smart hospitals as environments promoting healing by prioritizing the needs of the patients and the staff in their community settings, whether those settings are in the lush landscapes of Rwanda or in the bustling metropolis of Philadelphia.
