Abstract
from arXiv · showhide
Robots have the potential to be a game changer in healthcare: improving health and well-being, filling care gaps, supporting care givers, and aiding health care workers. However, before robots are able to be widely deployed, it is crucial that both the research and industrial communities work together to establish a strong evidence-base for healthcare robotics, and surmount likely adoption barriers. This article presents a broad contextualization of robots in healthcare by identifying key stakeholders, care settings, and tasks; reviewing recent advances in healthcare robotics; and outlining major challenges and opportunities to their adoption.
1. INTRODUCTION
Healthcare robotics could support people with disabilities or illness, caregivers, and clinical workers across diverse care environments. The article contextualizes these opportunities, reviews advances, and identifies adoption challenges requiring research and industry attention.
- Robots may enable people with cognitive, sensory, and motor impairments, assist ill or injured people, support caregivers, and aid the clinical workforce.
- 20% of the world’s population experience difficulties with physical, cognitive, or sensory functioning, mental health, or behavioral health.Of these individuals, 190 million experience severe difficulties with activities of daily living tasks.
- Healthcare faces a substantial labor shortage, leaving care workers overburdened and exposed to hazardous work environments and occupational injuries.
- Healthcare robotics has been applied to rehabilitation, surgery, telemedicine, drug delivery, and patient management in hospitals, clinics, homes, schools, and nursing homes.
- The article organizes its discussion around stakeholders, care settings, robot tasks, recent technologies, and adoption issues including capability, cost, clinical effectiveness, usability, acceptability, safety, and reliability.
2.1 Stakeholders
Healthcare robotics involves stakeholders who provide, receive, support, develop, administer, regulate, advocate for, or insure care. The article focuses on primary beneficiaries while emphasizing broader stakeholder involvement in deployment decisions.
- Stakeholders include direct robot users, clinicians, caregivers, robot makers, health administrators, policymakers, advocacy groups, and insurers.
- Primary beneficiaries are direct robot users, clinicians, and caregivers who are likely to use robotics technology regularly.
- Secondary beneficiaries include health administrators, robot makers, and environmental service workers involved in healthcare robotics without directly using robots to support direct users.
- Policymakers and advocacy groups are tertiary beneficiaries because they have an interest in robotic care but are unlikely to use robots directly.
- Although the article focuses on primary beneficiaries, all stakeholder groups are described as critical to successful healthcare robotics deployment and should be included in decision making when possible.
2.2 Care Settings
Care settings shape whether healthcare robots are suitable and what capabilities or designs they require. Healthcare administrators must also weigh how introducing robots may affect the health, safety, and well-being of users and clinicians.
- A robot’s suitability depends strongly on its care setting, which can affect its design and required capabilities.A large dual-arm mobile manipulator suitable for a laboratory may be inappropriate in an 80 sq. ft. assisted-living room.
- Longer term care settings: Selected settings include longer-term community facilities such as assisted living facilities, group homes, and custodial care facilities.
- Selected settings also include shorter-term facilities such as hospitals, with accessibility requirements varying across jurisdictions and facility types.
- Robots can disrupt care-setting health and safety, so health administrators must balance their risks and benefits for direct users and clinicians.
2.3 Care Tasks
Healthcare robots may support physical and cognitive tasks for direct users, clinicians, and caregivers, potentially reducing cognitive load amid demand that exceeds available care resources.
- Robots can provide physical and cognitive task support for direct users, clinicians, and caregivers.The article links task assistance to healthcare demand outpacing available resources and straining care workers.
2.4 Physical Tasks
Healthcare robots can support clinicians with hazardous, repetitive, and physically demanding work, while helping direct robot users perform daily activities. However, complex physical ADLs remain beyond practical standalone robots, whereas reach and mobility systems are closer to end-user deployment.
- Clinicians: “Dirty, dangerous, and dull” tasks, including transportation and patient movement, are valuable targets because they divert clinicians from patient care and create error risks.Patient movement is especially hazardous: healthcare and ambulance workers experience musculoskeletal injuries three to five times the national average.
- Clinicians: Robots can help clinicians treat highly infectious patients through telepresence and extend surgical access to areas constrained by tissue or distance.These applications include robot-mediated treatment and less invasive neurological, gastric, and fetal procedures.
- Direct Robot Users: Direct robot users need help with basic physical ADLs such as dressing, eating, ambulating, toileting, and housework.Workshop participants with ALS and other conditions emphasized practical assistance with everyday tasks.
- Direct Robot Users: Standalone robots performing most complex physical ADLs remain far from the consumer market because of dexterity, sensing, learning, speed, safety, and power constraints.Slow operation can frustrate users, while power budgets may make deployment impractical in many care settings.
- Direct Robot Users: Substantial gains have occurred in robots providing additional physical reach and mobility across settings, and these systems are likely to reach end-users first.Examples include smart prostheses, wheelchair-mounted arms, exoskeletons, and accessible personal transportation devices.
2.5 Cognitive Tasks
Robots can support cognitive work for clinicians, caregivers, and direct users, but the evidence and practical realization of these benefits remain uneven. Existing examples include clinical simulators, sensory assistance, workflow support, and rehabilitation or socio-emotional applications.
- Clinicians: Clinical robots may reduce workload by supporting patient logistics, charting, medication management, and other cognitive tasks when integrated with workflows and EHR data.The article presents workflow integration and EHR access as relevant conditions for these applications.
- Clinicians: Robotic patient simulators let inter-professional clinicians practice procedural and communication skills across specialties.The simulators can breathe, bleed, speak, expel fluids, respond to medications, and incorporate facial pathologies with physiological models.
- Direct Robot Users and Care Givers: Caregiver cognitive support remains underdeveloped, although robots might learn and anticipate needs, prefetch items, and handle time-intensive tasks.The passage links this opportunity to caregivers’ competing family, work, and health responsibilities.
- Direct Robot Users: Sensory augmentation, substitution, and robotic prosthetic feedback may help direct users with blindness, low vision, or limb loss.Examples include robotic wayfinding and tactile feedback from a robotic finger in a shoulder.
- Direct Robot Users: Rehabilitation and socio-emotional robots address cognitive recovery, companionship, emotion learning, and dementia symptoms, but few trials compare direct-user benefit with standard treatment.The limited clinical-effectiveness evidence leaves the future of these applications unclear.
3. RECENT ADVANCES IN HEALTHCARE ROBOTICS
Recent healthcare robotics spans internal, wearable, and external systems serving direct users, caregivers, and clinicians across clinical and care settings. Advances target therapy, surgery, rehabilitation, mobility, physical assistance, infectious disease treatment, training, and companionship, while future work addresses interaction, uncertainty, and real-time registration.
- Overview: The 2016 US Robotics Roadmap identifies aging and quality of life, surgical and interventional robotics, rehabilitation, and clinical workforce support as major healthcare focus areas.More than 150 robotics researchers contributed to the roadmap.
- Overview: Healthcare robots can be categorized as inside, on, or outside the body, with potential for physical and cognitive support across care settings and clinical foci.Internal and wearable systems primarily target direct users, while external systems also serve caregivers and clinicians.
- Inside the Body: Internal robotics advances include microrobots for targeted therapy, material removal, structural control, and sensing, alongside surgical and interventional systems improving dexterity and visualization.Concentric-tube robots provide steerable, teleoperated manipulation within the body.
- Inside the Body: Future internal-robot research emphasizes intuitive physical and cognitive interaction, uncertainty management, and real-time 3D registration in tissue.These directions cover both deformable and non-deformable tissue environments.
- On the Body: Wearable robotics includes prostheses, orthoses, and exoskeletons that restore, assist, or enhance physical capability for users with limb loss or weakness.Recent advances include neural integration for tactile feedback, broader workspace and range of motion, and improved comfort.
- Outside the Body: External robots support infectious-disease treatment, remote surgery, patient movement, clinical training, mental and behavioral healthcare, reach, navigation, telepresence, and potential medical-supply delivery.The figure frames external robots as serving direct users, caregivers, and clinicians across care settings.
4. HEALTHCARE ROBOTICS ADOPTION: CHALLENGES AND OPPORTUNITIES
Healthcare robot adoption is constrained by usability, acceptability, safety, capability, effectiveness, cost, and real-world integration. The paper outlines design, evaluation, regulatory, and workflow approaches for addressing these barriers.
- Usability and Acceptability: Healthcare deployment requires attention to usability and acceptability because difficult or stigmatizing robots may be abandoned or avoided.Clinician technology literacy, exclusion of direct robot users from design, and disability-related stigma can reduce practical adoption.
- Usability and Acceptability: Lower-complexity, service-centered designs can improve controllability, maintainability, reliability, and fit with the broader caregiving ecosystem.The paper recommends functional simplicity and designing around multiple stakeholders rather than a single user-system pairing.
- Safety and Reliability: Safety remains critical because robots operate around vulnerable people, while safe cognitive human-robot interaction remains substantially underexplored.Proposed safeguards include transparency, privacy, dignity, and aligning a robot’s appearance with its function.
- Capability and Function: Healthcare robots must function robustly in open-ended, variable settings where demonstrations often fail and perception is disrupted by motion, occlusion, sensor loss, and clutter.Multi-modal sensing, lifelong learning, contextual modeling, and object or environmental affordances are identified as potential aids.
- Cost Effectiveness: Cost effectiveness should include downstream workflow effects, since poorly integrated systems can create non-value-added work rather than saving time.Acquisition decisions should examine institutional readiness, intended goals, deployment plans, success measures, and existing workflow.
- Clinical Effectiveness: Evidence and regulation must support healthcare deployment: direct-user robots require effectiveness research, while regulatory coverage varies by device type.In-body and many on-body robots generally require approval, whereas some outside-the-body robots fall within existing classifications.
5. DISCUSSION
Healthcare robotics could benefit stakeholders across settings, but its integration remains uncertain. The paper therefore calls for cautious, evidence-based development with direct robot users involved throughout the project lifecycle.
- Discussion: Healthcare robotics is an emerging field with recent advances and potential benefits across stakeholders and care settings.The paper states that the eventual integration of robots into beneficiaries’ lives remains unknown.
- Discussion: Research and industry should jointly establish a strong evidence base and consider the full context of care before broad deployment.The paper warns that technology development and deployment in isolation can harm direct users, burden clinicians, and create hidden costs.
- Discussion: Direct robot users should participate throughout research, development, and deployment because ignoring their input can produce unusable, unsuitable, and abandoned robots.The paper points to PCORI as a model for engaging primary stakeholders in clinical research and development.
- Discussion: Robot makers should work with direct users to bridge technology-literacy gaps and set realistic expectations about robots’ fallibility.The paper notes that media portrayals often fail to reflect robots’ real-world limitations.
