For example, AI can use patient feedback and social media data to personalise communication campaigns, increasing patient engagement and attracting new patients.

2.1.2. Staffing:

  AI-enabled solutions can aid workforce planning by forecasting fluctuations and peak times for hospital admissions and discharges. This capacity enables better distribution of human and material resources, such as organising a float pool of nurses during peak hours or managing agency staffing needs. Hartford HealthCare’s artificial intelligence initiatives have evolved hospital operations, particularly staff scheduling and operating space availability (Hartford HealthCare, 2024). ShiftWizard, an AI-powered workforce management system, enables optimised staffing alignment with patient care needs. Hartford HealthCare’s Holistic Hospital Optimisation (H2O) system employs predictive analytics to streamline many elements of hospital operations, resulting in a 20 per cent increase in staff utilisation and a 15 per cent decrease in overtime expenditures.

2.1.3. Recruitment and Training: 

AI contributes to recruiting by analysing candidate data and efficiently matching job criteria. Furthermore, AI-powered training programme personalise learning experiences for healthcare employees, enabling ongoing professional development and increased engagement (Merraine Group, 2024). AI technologies, such as HireVue, employ machine learning to screen and evaluate prospects, expediting the recruitment process. This AI-powered recruitment and training platform decreased hiring time by 30 per cent while increasing employee retention by 15 per cent.

AI-powered platforms make recruitment easier by matching candidates to job needs based on previous data and performance indicators. AI-powered solutions like Coursera for Business provide personalised learning paths for healthcare employees, assuring continual professional development.

2.2. Clinical Operations

2.2.1. Treatment Pathways and Clinical Decision Support:

Clinicians traditionally relied on experience and limited data for decision-making. AI enhances clinical decision-making with Natural Language Processing (NLP) for data extraction, Generative AI for treatment simulations, and Robotics for precise surgeries. For example, AI systems use patient data to personalise treatment approaches, resulting in superior clinical outcomes (Keskinbora, 2020; Nature, 2024b). IBM Watson for Oncology, an AI-powered clinical decision support system, assists oncologists by making evidence-based therapy recommendations. Studies demonstrate that AI help improves diagnostic accuracy by 10-15 per cent.

2.2.2. Continuum of Care:

AI enables continuous patient monitoring via wearables and remote monitoring systems, allowing for real-time data analysis and prompt actions. This has resulted in a considerable reduction in hospital readmissions and improved patient management in critical care units, as seen by the deployment of AI in NICUs and PICUs (American Academy of Pediatrics, 2021; Schwartz, 2021). EarlySense and Philips IntelliVue Guardian Solutions for NICUs and PICUs. AI algorithms analyse continuous streams of patient data, identifying probable issues and allowing for prompt interventions, which reduces adverse occurrences by 20-25 per cent.

2.3. Patient Outcomes and Experience

2.3.1. Safety and Quality:

AI has improved patient safety by minimising medical errors via precise diagnostics and predictive analytics. Machine learning models for hospital readmission prediction have shown to enhance patient outcomes by identifying high-risk patients and enabling preventive therapy (Keskinbora, 2020; Schwartz, 2021). The Sepsis Watch system at Duke University Hospital, for example, employs AI to detect early indicators of sepsis and warn healthcare providers, allowing for timely intervention. These AI-powered predictive analytics identified sepsis risk in patients, resulting in a 12 per cent reduction in fatality rates. AI’s ability to analyse massive volumes of data can dramatically improve medical care. Implementing other AI tools, such as Butterfly Network’s handheld ultrasound devices, can democratise access to advanced diagnostic capabilities, delivering real-time insights and decreasing the learning curve.

2.3.2. Enhanced Interaction:

AI-powered chatbots and virtual assistants respond to patients’ inquires promptly, enhancing patient communication and satisfaction. These methods ensure that patients receive timely information and support, thereby improving their overall experience (Nature, 2024a). Examples include the Mayo Clinic’s AI chatbot, which assists patients with pre-visit planning and post-visit follow-up. Patients report a 30 per cent improvement in satisfaction due to immediate, precise responses to their concerns. 

To encourage conventional practitioners to integrate AI, it is critical to highlight the complementary nature of these technologies. AI should be positioned as a tool that supplements rather than replaces clinical judgement. Training programme and workshops that demonstrate AI’s ability to reduce effort and improve diagnostic accuracy can increase acceptability among seasoned practitioners.

2.4. Patient Access

2.4.1 Remote Monitoring and Telehealth:

AI facilitates telehealth services, allowing patients to obtain care from a distance. This has been especially effective during the COVID-19 outbreak, allowing for continuous care without the need for physical visits. Remote patient monitoring with AI-powered solutions has enhanced access to healthcare services, particularly for patients living in distant places (Keskinbora, 2020; Schwartz, 2021). Systems such as Biofourmis’ Biovitals use artificial intelligence to continuously monitor patient health and offer clinicians with meaningful findings.
