What are the disadvantages of modular operating rooms?

Modular operating rooms are a construction model that transforms complex operating room and medical clean space projects into customizable industrial products. The following will introduce them from dimensions such as their advantages, constituent modules, and application scenarios:
Advantage
Build efficiently
Shorten the cycle: By adopting factory prefabrication and on-site assembly methods, the on-site construction time and cycle are significantly reduced, enabling it to be put into use more quickly compared to traditional operating rooms.
Reducing interference: The feature of rapid construction makes the construction of operating rooms have a relatively small impact on the daily operation of the hospital, enabling the resumption of surgical services more quickly and reducing interference with the normal medical order of the hospital.
Cost savings
Reduced construction costs: Prefabrication in factories reduces the material and labor costs required for on-site construction while avoiding additional expenses caused by long construction periods.
Optimal resource allocation: Different modules can be selected based on actual needs, such as operating tables, surgical lamps, surgical instruments, clean areas, purification systems, etc., to achieve optimal resource allocation and further reduce costs.
Environmental protection and safety
Green and environmental protection: During the factory production process, high-tech environmental protection equipment and materials are adopted, reducing construction waste and dust pollution, which meets the requirements of green buildings.
Construction safety: During the assembly process, no welding, spraying, cutting or other techniques are required, reducing uncontrollable human factors and enhancing construction safety. Meanwhile, the interior of its wall panels is made of fireproof materials, which have reliable hardness and fireproof performance.
Advanced function
Surgical environment optimization: By using high-efficiency filters and airflow control, the cleanliness of the surgical area is ensured, reducing microorganisms and particulate matter in the air, and improving the quality of the surgical environment.
Digital integration: Innovate and integrate digital functions such as real-time medical image transmission systems and intelligent equipment efficiency control modules to build a digital platform covering the entire process from preoperative, intraoperative to postoperative, achieving data interconnection and interoperability of core medical equipment and real-time image sharing of hospital information systems, significantly enhancing the efficiency of surgical collaboration.
Flexible expansion
Flexible layout: It can be quickly assembled and adjusted according to requirements. The area, layout, and configuration of the operating room can be expanded or reduced according to different needs.
Convenient upgrade: With the continuous advancement of medical technology, modular operating rooms can be conveniently upgraded and replaced to meet new surgical demands and technical requirements, such as replacing more advanced medical equipment and upgrading digital systems.
Component module
Infrastructure modules: including supply air ceilings, door frames, anchor foundations, columns, beams, etc., are the basic components that constitute the space of the operating room.
Enclosure structure module: It is usually assembled with high-quality laminated plates, electrolytic steel plates stainless steel plates, and other materials, featuring excellent sealing performance, corrosion resistance, and easy cleaning. The overall wall appearance is beautiful and the gaps are tight.
Purification air conditioning module: It is responsible for filtering, purifying, and regulating the air in the operating room, providing appropriate temperature, humidity, and airflow, and ensuring the cleanliness of the surgical environment.
Electrical system module: It includes lighting equipment, power sockets, distribution boxes, monitoring systems, etc., providing a safe and stable power supply and electrical control for the operating room, and meeting various power demands during the surgical process.
Medical equipment modules: such as operating tables, surgical lamps, anesthesia machines, monitors, ventilators, endoscopic systems, imaging equipment, etc. These devices have been carefully selected and configured to meet the needs of different types of surgeries.
Digital system module: It integrates the main instrument control systems in the operating room to achieve integrated digital control. It also includes a real-time medical image transmission system, surgical process management system, remote consultation system, etc., improving the informatization level and collaborative efficiency of the surgery.
Application scenarios
General hospitals: They can be used for various surgical operations, such as general surgery, cardiothoracic surgery, neurosurgery, obstetrics and gynecology, orthopedics, etc., meeting the surgical needs of different departments and improving the overall surgical efficiency and quality of the hospital.
Specialized hospitals, such as ophthalmic hospitals, dental hospitals, and medical aesthetics hospitals, can customize specialized modular operating rooms based on their characteristics and needs, and equip them with corresponding professional equipment and facilities to provide patients with more precise and professional surgical services.
Primary medical institutions: For some primary hospitals, health centers, or clinics, modular operating rooms can be quickly set up to solve the problem of insufficient surgical facilities, enabling them to perform some common minor surgeries and enhancing the capacity of primary medical services.
Emergency medical rescue: In response to natural disasters, public health events, and other emergencies, modular operating rooms can be quickly transported to the site for assembly, providing timely surgical treatment for the injured. They are an important part of the emergency medical rescue system.
Four pieces of materials
What are the disadvantages of modular operating rooms?
Although modular operating rooms have significant advantages such as high efficiency and flexibility, there are also some limitations in practical applications. The following are their main disadvantages and analyses:
First, the initial investment cost is relatively high
Modular design and prefabrication cost:
Modular operating rooms need to be prefabricated with high precision in the factory (such as purification systems and electrical equipment integration), and the technical threshold in the design and production process is relatively high, resulting in a significantly higher initial procurement cost than traditional operating rooms (usually 20% to 30% higher).
Transportation and installation costs:
Large modules require professional transportation teams and equipment (such as cranes), and the transportation cost increases with distance. On-site installation requires precise debugging (such as the air volume balance of the air purification system), which may incur additional labor and technical service costs.
Adaptation transformation cost:
If the hospital building structure does not match the modular dimensions (such as insufficient floor height or restricted load-bearing capacity), the building itself needs to be renovated, further increasing the overall cost.
Second, there are limitations to spatial flexibility
The fixed module size leads to difficulties in layout adjustment:
Modular components are usually of standardized sizes (such as the common 3.6m×5.4m single-room module), and although they can be combined into different layouts, they are difficult to adapt to irregular architectural Spaces (such as curved walls and irregular floors).
Overall coordination is required for later expansion:
The newly added modules need to be reconnected with the existing systems (such as purification air conditioning and electrical circuits), which may encounter problems such as conflicts in pipeline routing and incompatibility of control systems. The complexity of expansion is higher than the "partial expansion" of traditional operating rooms.
Insufficient adaptation to special surgical requirements:
For super-large-scale surgeries (such as organ transplants, and combined surgeries) or scenarios requiring special equipment (such as intraoperative CT, and robotic surgical systems), modular space may be limited by preset dimensions and it is difficult to flexibly adjust the placement of equipment.
Third, the complexity of maintenance and upgrade is relatively high
High system integration leads to difficulties in troubleshooting:
The purification, electrical, and digital systems of the modular operating room are highly integrated within the wall panels or ceiling. Once a fault occurs (such as pipe leakage or aging wiring), the modular structure needs to be disassembled for maintenance, which takes a long time and may affect the operation of adjacent areas.
Equipment upgrade requires overall linkage:
The replacement of large equipment (such as surgical lamps and imaging systems) may involve the modification of module structures or the re-layout of pipelines. For instance, in traditional operating rooms, ceiling lamps can be directly replaced, while in modular operating rooms, the entire top module needs to be replaced, significantly increasing both costs and construction time.
High dependence on the accessory supply chain:
Some modular components (especially imported brands) need to be purchased from specific suppliers. If the modules are discontinued or the models are phased out, there may be a shortage of spare parts for later maintenance, which will affect the long-term availability of the operating room.
Fourth, it has strict requirements for the basic environment
Building load-bearing capacity and space requirements:
The modular operating room has a relatively large self-weight (including equipment modules), the floor load-bearing capacity of the building must be ≥800kg/m² and the floor height must meet the requirements for module hoisting (usually ≥3.5m). Old hospitals or grassroots buildings may need to carry out structural reinforcement in advance.
The operation of the purification system relies on stable energy.
The purification air conditioning system needs to operate continuously for 24 hours and has extremely high requirements for power supply (dual power supply is needed) and water source (constant temperature and pressure). In the event of a power outage or energy failure, it may cause the operating room to lose power rapidly, making it more vulnerable compared to traditional operating rooms.
Transportation and installation environment restrictions:
Module transportation needs to avoid narrow roads or Bridges (the size of a single module is usually ≥3m×2.5m), and it may be difficult to implement in traffication-restricted areas such as mountainous areas and urban centers. On-site installation requires a dust-free environment. If there is a lot of dust during outdoor construction, it may affect the sealing test of the module.
Five, it is difficult to realize personalized demands
Homogenization of design styles
Most modular components are produced in a standardized manner, and the wall materials (such as electrolytic steel plates) and color combinations are relatively monotonous, making it difficult to meet the personalized demands of high-end hospitals for the aesthetic design of operating rooms (such as soft lighting and wood grain decoration).
Insufficient flexibility in the prevention and control of special infections:
For highly contagious surgeries (such as COVID-19 and tuberculosis), the negative pressure switching and airflow organization adjustment in modular operating rooms rely on preset ventilation modules. Compared with the "customized negative pressure transformation" of traditional operating rooms, the response speed to sudden infection demands is relatively slow.
Vi. Potential Problems During Long-term Use
Attenuation of sealing performance at the module joint
After long-term use, the sealing strips between the modules may age and crack, resulting in a decrease in the air tightness of the clean area and an increased risk of microbial contamination. They need to be replaced regularly (the replacement cycle is usually 5 to 8 years), incurring additional maintenance costs.
Risk of uneven ground load:
The frequent movement of surgical equipment (such as C-arms and robots) may cause local compressive deformation of the module ground, affecting the stability of the overall structure. Regular load detection and structural reinforcement are required.
Summary: Applicable scenarios and optimization suggestions
The disadvantages of modular operating rooms mainly lie in aspects such as initial cost, space limitations, and maintenance complexity. However, their advantages of high efficiency and standardization remain irreplaceable in new hospitals, emergency medical care, and standardized surgical scenarios.
Optimization direction:
Cost control: Cooperate with suppliers to develop the "regional shared leasing" model of modular components to reduce the procurement costs of small and medium-sized hospitals;
Technological upgrade: Adopt a "detachable modular design" (such as magnetic wall panels) to enhance the efficiency of later maintenance and equipment replacement;
Flexible adaptation: Develop a combination solution of "micro modules" (such as 2.4m×3.6m) and "expansion modules" to meet the needs of minor surgeries and special scenarios.
In practical applications, it is necessary to combine the hospital's scale, the type of surgery, and long-term planning, weigh the advantages and disadvantages of modular operating rooms, and select the most suitable construction plan.
