Introduction

Robots are machines that can perform tasks that normally require human intelligence, skill, or physical ability. Robots can be controlled by humans, computers, or other robots, and they can use various sensors, actuators, or tools to interact with their environment.

Robots are playing an increasingly important role in healthcare, from assisting with surgery to providing patient care. According to a report by [MarketsandMarkets], the global market for medical robots is expected to grow from $6.8 billion in 2020 to $23.6 billion by 2025, at a compound annual growth rate of 28.1%. The report also identifies some of the key drivers for the growth of medical robots, such as technological advancements, the aging population, rising demand for minimally invasive surgery, and increasing funding and investments.

The use of robots in healthcare can provide various benefits, such as improved precision and accuracy, reduced patient trauma and recovery time, increased efficiency and productivity, enhanced surgical capabilities, and improved patient care. However, there are also some challenges and drawbacks associated with robots in healthcare, such as high cost, complexity and difficulty of use, potential for technical failure, and ethical concerns about job displacement.

In this article, we will explore the advantages and disadvantages of robots in healthcare and how they can impact the quality and efficiency of healthcare services. We will also discuss the future of robots in healthcare and how to ensure their safe and ethical use.

Advantages of Robots in Healthcare

Robots in healthcare can offer several advantages over traditional methods or human workers. Some of the main advantages of robots in healthcare are:

Improved precision and accuracy

Robots can perform tasks with greater precision and accuracy than humans, especially when dealing with delicate or complex procedures or situations. Robots can use various sensors, cameras, or lasers to measure, monitor, or guide their movements and actions. Robots can also use various algorithms, software, or artificial intelligence to process and analyze data and information. Robots can reduce the risk of human error, variability, or inconsistency that may affect the quality or outcome of healthcare services.

For example, [da Vinci Surgical System] is a robotic surgical system that allows surgeons to perform minimally invasive surgery with enhanced vision, control, and precision. The system consists of a console where the surgeon sits and controls the robotic arms that hold the surgical instruments and a patient-side cart where the robotic arms are attached to the patient’s body. The system uses a high-definition 3D camera that provides a magnified view of the surgical site, and a computer that translates the surgeon’s hand movements into precise and scaled motions of the robotic arms.

Reduced patient trauma and recovery time

Robots can reduce the trauma and recovery time for patients who undergo surgery or treatment by minimizing invasiveness, blood loss, pain, or infection. Robots can use smaller incisions, less anesthesia, or less radiation than conventional methods, which can result in faster healing, shorter hospital stays, or lower complications.

For example, [CyberKnife] is a robotic radiosurgery system that delivers high doses of radiation to tumors or lesions with sub-millimeter accuracy. The system consists of a linear accelerator that generates radiation beams and a robotic arm that moves around the patient’s body to deliver the beams from different angles. The system uses real-time imaging and motion tracking to adjust the beams according to the tumor’s position and shape. The system can treat tumors or lesions anywhere in the body without surgery or incisions.

Increased efficiency and productivity

Robots can increase the efficiency and productivity of healthcare services by performing tasks faster, more consistently, or more reliably than humans. Robots can also perform multiple tasks simultaneously or continuously without fatigue or distraction. Robots can free up human workers from repetitive, routine, or mundane tasks, and allow them to focus on more complex, creative, or meaningful tasks.

For example, [TUG] is a robotic delivery system that transports materials such as medications, supplies, or meals within hospitals or clinics. The system consists of a mobile robot that navigates autonomously using sensors and maps and a cart that carries the materials. The system uses wireless communication to receive requests from staff or patients and to interact with doors, elevators, or security systems. The system can deliver materials faster, more safely, or more securely than human workers.

Enhanced surgical capabilities

Robots can enhance the surgical capabilities of healthcare professionals by enabling them to perform new or complex procedures that may be impossible or difficult with conventional methods. Robots can also extend the reach or access of healthcare professionals to remote or inaccessible areas or populations.

For example, [REACH] is a robotic telemedicine system that allows doctors to examine and treat patients remotely using a mobile robot. The system consists of a robot that moves around the patient’s location using sensors and cameras and a tablet that displays the doctor’s face and voice. The system uses a wireless connection to transmit video and audio between the robot and the doctor. The system can also use various attachments such as stethoscopes, thermometers, or ultrasound probes to collect vital signs or images from the patient. The system can provide healthcare services to patients who live in rural or isolated areas or who have limited mobility or transportation.

Improved patient care

Robots can improve patient care by providing emotional, social, or physical support to patients who need assistance or companionship. Robots can also monitor, remind, or motivate patients to follow their treatment plans or to improve their health behaviors.

For example, [Paro] is a robotic seal that provides therapeutic benefits to patients who suffer from dementia, depression, or loneliness. The robot is designed to look and feel like a real seal, and it can respond to touch, sound, or light by moving its head, tail, or flippers. The robot can also make sounds or expressions that mimic those of a real seal. The robot can stimulate the patients’ senses and emotions, and reduce their stress or anxiety.

Disadvantages of Robots in Healthcare

Robots in healthcare also have some disadvantages or drawbacks that may affect their feasibility or acceptability. Some of the main disadvantages of robots in healthcare are:

High cost

Robots are expensive and require a large investment to purchase, install, operate, or maintain. Robots may also incur additional costs such as training, licensing, insurance, or maintenance. Robots may not be affordable or accessible for all healthcare providers or patients, especially in low-resource or developing settings.

For example, according to a report by [Intuitive Surgical], the manufacturer of da Vinci Surgical System, the average cost of the system is $2 million, and the annual maintenance cost is $180,000. The report also estimates that the average cost of a da Vinci surgery is $3,000 more than a conventional surgery. The high cost of the system may limit its availability or adoption by hospitals or clinics, especially in rural or underserved areas.

Complexity and difficulty of use

Robots are complex and require a high level of skill and knowledge to use effectively and safely. Robots may also pose technical or operational challenges such as compatibility, interoperability, or reliability. Robots may require extensive training, testing, or certification for healthcare professionals or staff to use them properly. Robots may also require constant supervision, monitoring, or troubleshooting to prevent errors, malfunctions, or accidents.

For example, according to a study by [Johns Hopkins University], there were 144 deaths and 1,391 injuries associated with robotic surgery between 2000 and 2013 in the US. The study also identified some of the common causes of robotic surgery complications such as system errors, user errors, communication errors, or design flaws. The study suggests that there is a need for more rigorous training, testing, and reporting for robotic surgery systems and users.

Potential for technical failure

Robots are vulnerable to technical failure due to various factors such as hardware defects, software bugs, power outages, network disruptions, cyberattacks, human errors, or natural disasters. Technical failure can compromise the functionality or performance of robots and cause harm or damage to patients, healthcare professionals, staff, equipment, or facilities. Technical failure can also result in legal liabilities, financial losses, reputational damages, or trust issues for healthcare providers or patients.

For example, according to a report by [BBC News], a robot malfunctioned during a prostate surgery at Royal Cornwall Hospital in 2015 and caused severe internal injuries to the patient. The report also revealed that there were 62 incidents involving robots at NHS hospitals between 2015 and 2017. The report suggests that there is a need for more regulation, oversight, and accountability for robots in healthcare.

Ethical concerns about job displacement

Robots may pose ethical concerns about job displacement as they may replace human workers in some tasks or roles in healthcare. Job displacement may affect the employment status, income level, career development, or job satisfaction of healthcare professionals or staff. Job displacement may also affect the quality or continuity of healthcare services as robots may lack human skills such as empathy, compassion, creativity, or judgment.

For example, according to a report by [PwC], up to 30% of UK jobs could be at risk of automation by 2030. The report also predicts that health and social work is one of the sectors that could be most affected by automation. The report suggests that there is a need for more education, training, or reskilling for workers who may be affected by automation.
