This study will conclude with 5 case studies of top U.S. hospitals that have adopted AI for diverse purposes.

• Electronic Health Records (EHR): AI can help manage and analyze electronic health records, reducing the risk of errors and streamlining administrative tasks. AI can also assist in identifying patterns and trends in patient data that can lead to better care (Topol, 2019).
In addition to delivering enormous benefits to patients, AI also brings tremendous benefits to the management, operation, and competitiveness of the healthcare organization. AI can make the organization more efficient, effective, and competitive in the marketplace. AI can help healthcare organizations reduce costs and achieve differentiation at the same time by improving operational efficiency, reducing waste, and enhancing patient outcomes. Below are some specific ways AI can achieve these goals: 1. Administrative chores: AI can be used to handle administrative work such as meeting scheduling, invoicing, and insurance claims handling, allowing staff to concentrate on patient outcomes (Deshpande, 2020).
2. Predictive maintenance: AI can be used to anticipate machine malfunctions and plan maintenance before they occur, decreasing delay and replacement costs (Dubovitskaya et al., 2018).
3. Supply chain management: AI can be used to optimize inventory levels, reducing the risk of overstocking or stockouts, which can lead to waste and increased costs (Liu et  6. Fraud detection: AI can be used to detect fraudulent insurance claims, reducing costs for both hospitals and patients (Fong & Wong, 2017).

Challenges of AI in Healthcare
The adoption and deployment of AI in healthcare can potentially revolutionize patient care, improve diagnosis, and increase efficiency. However, while the opportunities to apply AI in healthcare seem endless, AI deployment also poses significant challenges. These challenges can be grouped into the following categories: operational and technical, management, and ethical and legal.

Operational & Technical Challenges
(a) Data Issues: AI systems depend on huge amounts of data to learn, adapt, and make decisions. However, data quality and quantity can be challenging in healthcare. Data can be inconsistent, incomplete, or missing. Therefore, data quality assurance, data cleaning, and data curation are critical steps to ensure that AI models generate accurate and reliable outputs (Chen et al., 2019). Many healthcare organizations struggle to manage and integrate data from multiple sources, leading to incomplete or inconsistent data sets that can negatively impact AI performance (Topol, 2019).
(b) Technical Challenges: One of the primary technical challenges is the need for robust and reliable algorithms. AI requires complex algorithms that can analyze and interpret large amounts of data to make accurate predictions. However, developing and validating these algorithms can be time-consuming and challenging, requiring significant expertise in machine learning and data science (Topol, 2019). Also, AI systems require robust and scalable infrastructure, specialized hardware, and software. These technical requirements can be costly, and organizations may not have the resources to invest in the necessary infrastructure (Ku et al., 2018). Another technical challenge is the need for interoperability between different systems and platforms (Mandl et al., 2018). Healthcare organizations often use multiple software systems and data formats, which can make it difficult to integrate AI systems into existing workflows (O'Reilly & Choi, 2020). Interoperability standards and protocols need to be established to ensure seamless integration of AI into existing healthcare systems.

Management Challenges
(a) Strategic Planning: AI initiatives often fail because they are implemented as standalone projects. To ensure the success of AI efforts, AI must be integrated into the strategic planning process so that it aligns with the goals and objectives of the organization.
(b) Training Challenges: To ensure that AI applications are used effectively and appropriately, healthcare workers must be trained in their use. This includes not only technical training but also understanding how the technology impacts patient care and fits into the larger healthcare system.
(c) Acceptance and Adoption: AI adoption in healthcare depends on the acceptance and buy-in from healthcare providers, patients, and regulators. Stakeholders need to be convinced that AI applications are safe, effective, and beneficial to patients (Cresswell & Sheikh, 2017).

Legal & Ethical Challenges
(a) Regulatory Compliance: Healthcare is a highly regulated industry, and AI applications need to abide by certain laws and regulations, including the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA). Moreover, there are concerns about liability and accountability when AI models make decisions that affect patients' health outcomes (Ku et al., 2018).
(b) Ethical issues: Ethics plays a critical role in the creation and implementation of AI systems. As AI becomes more advanced and pervasive in society, ethical considerations become increasingly important to make sure that AI is used in a way that is just, impartial, and beneficial to society (Jobin et al., 2019). The section below further elaborates on the key ethical issues relating to AI in healthcare.

Ethical Concerns
A survey by IBM Watson Health found that 82% of respondents believe that ethical considerations are important concerning the use of AI in healthcare (IBM Watson Health, 2020). Similarly, a report by the HIMSS (2020) found that 60% of healthcare organizations are concerned about ethical issues related to the usage of AI in health matters (HIMSS, 2020).
Below are some of the key ethical issues concerning the adoption and deployment of AI in healthcare: 1. Privacy and Security: The World Health Organization found that there are significant ethical challenges when it comes to the use of AI in healthcare. These issues involve bias, transparency, and privacy. AI systems require access to large amounts of personal health data, which can include sensitive information such as genetic data, medical history, and lifestyle choices. This raises concerns about data privacy and security. Patients need to be confident that their data is being used ethically and securely (WHO, 2021).

Bias and Fairness: A survey by the Pew Research
Center found that 75% of Americans are concerned about AI being used to make decisions about their medical care, with concerns around accuracy and fairness (Pew Research Center, 2018). If somehow the data used to teach AI algorithms is not accurately reflecting the community, the algorithms may be biased. This can have unjust and biased consequences, especially for disadvantaged groups. To prevent perpetuating biases, it is critical that AI algorithms be educated on varied and representative information. (Mittelstadt et al., 2016).
3. Transparency and Explainability: Because AI models are frequently regarded as "black boxes," it can be challenging to comprehend how they came to a specific conclusion. For healthcare professionals who have to explain to patients the reasoning behind treatment choices, this absence of transparency can be troublesome. Therefore, it is crucial to develop AI models that are transparent and explainable (Mittelstadt et al., 2016).
4. Autonomy and Responsibility: AI systems can make decisions that affect patient outcomes. Therefore, it is essential to ensure that patients are aware of the role of AI in their treatment and that healthcare providers retain the autonomy to override AI recommendations if necessary (WHO, 2021).
5. Accountability and Liability: Finally, AI raises questions about accountability and liability. Who is in charge if a patient suffers damage as a consequence of an AI system's error? Who is to blame-the creator, the medical professional, or the sufferer themselves? Therefore, it is crucial to establish clear lines of accountability and liability for AI in healthcare (Kaye et al., 2019).
Overall, addressing these ethical issues is critical to ensuring that AI is used ethically and responsibly in healthcare.

Managerial Implications
The use and adoption of AI in the healthcare industry have significant managerial implications that should be carefully considered.
One of the primary managerial implications of AI in healthcare is the need for strategic planning and investment. Healthcare organizations must develop a clear strategy for the integration of AI that aligns with their overall business goals and objectives. This includes identifying the specific AI applications that are most relevant to their operations and investing in the necessary infrastructure and resources to support the technology.
Second, there is a need for healthcare organizations to invest in data infrastructure and management systems that can handle the large volumes of data generated by AI applications. This includes having robust data governance and security frameworks in place to ensure patient data privacy and security (Alvarez-Rodríguez et al., 2021).
Another implication is that healthcare organizations must develop new organizational structures and work processes to effectively integrate AI into their operations. This may involve retraining or hiring new staff with expertise in AI and related technologies, as well as redesigning processes to incorporate AI algorithms and decision-making . Healthcare workers need to be trained in the delivery of AI applications to make sure that they are used accurately and appropriately. This involves not only training in the technical aspects of using the technology but also understanding how it potentially impacts the patient and fits into the broader healthcare system.
Furthermore, the adoption of AI in healthcare also requires a thorough understanding of ethical and social implications. Healthcare organizations must ensure that AI structures and systems are utilized and deployed in an accountable and just manner, taking into account issues such as bias, fairness, and transparency (Raza et al., 2020).
Data privacy and security also carry significant managerial implications for AI deployment in healthcare. Healthcare organizations must make sure that patient data is protected and that the use of AI complies with data privacy laws such as HIPAA. This requires careful management of how data is stored, accessed and shared, as well as the use of appropriate encryption and other security measures.
Finally, AI's use in healthcare can potentially impact the quality and costs of healthcare. Healthcare managers need to assess the financial and clinical implications of AI adoption and determine how to balance the benefits of AI against its costs .
Overall, the adoption of AI in healthcare warrants a thorough consideration of its managerial implications, including data infrastructure and management, organizational structure and workflows, ethical and social implications, and financial and clinical implications.

Limitations of Study and Suggestions for Future Research
The present study has focused only on the adoption and impact of one type of technology (i.e., AI) in the healthcare industry.

3. Augmented and virtual reality: AR/VR technologies are being increasingly used in healthcare to improve patient outcomes, medical training, and patient education. For example, they are used to simulate surgeries, medical procedures, and anatomical models to train medical students, residents, and physicians (McClelland, 2020). They are also used to distract patients from pain during medical procedures or treatments like chemotherapy (Gutierrez, 2020). Furthermore, they are used in the management of mental health issues, including PTSD, depression, and anxiety (Pittenger, 2020). Last but not least, they are used in physical therapy and rehabilitation to help patients regain mobility, strength, and function (Sadi, 2019).

4.
Blockchain: This is a distributed ledger technology that makes it possible to share and store data in a safe, open, and decentralized manner. It can potentially transform healthcare by improving data security, interoperability, and patient privacy. Blockchain can also help to streamline administrative processes and reduce costs (Mettler et al., 2019).

3D printing:
A digital file is used in the 3D printing process to produce three-dimensional things. It is being utilized in healthcare to produce individualized implants, prostheses, and medical equipment. Organ and tissue replicas may also be produced using 3D printing for surgery planning and medical teaching (Wong et al., 2016).
6. Robotics: Robotics is increasingly being used in healthcare for tasks such as surgery, medication delivery, and patient monitoring. Robotic systems can improve the precision and accuracy of procedures, reduce the risk of human error, and enable remote healthcare delivery (Kumar et al., 2023).
The authors recommend that future researchers should dive into each of these technologies and uncover their immense potential in the management and delivery of healthcare.

Conclusion
In conclusion, the adoption and deployment of AI in the healthcare industry can bring tremendous benefits to both the patient and the healthcare organization. However, AI in healthcare also poses challenges and concerns, such as ethical and legal issues, bias, security and confidentiality of data, and the necessity for qualified personnel to understand and handle the data, among other issues. Together with other developing technologies, AI is anticipated to play an increasingly bigger role in the future of healthcare as technology develops and gets better. To ensure the moral and ethical use of AI in healthcare, healthcare organizations and politicians must create rules and laws.
