What is IoT in Healthcare?

IoT in healthcare is a term that refers to a network of connected devices that collect and exchange data to improve patient outcomes. These IoT devices range from wearable health monitors and smart thermometers to advanced implantable devices and remote patient monitoring systems.

Why is IoT Important in Healthcare?

IoT is soon to become an indispensable part of modern healthcare as it primarily focuses on improving the efficiency and quality of patient care. IoT devices in healthcare collect and transmit real-time health data to healthcare providers. This information can be used for a variety of purposes, from early diagnosis and personalized treatment plans to continuous monitoring of patient conditions minus the need for invasive procedures.  

For example, wearable medical devices within the IoT framework enable Remote Patient Monitoring (RPM). These devices can monitor patients for different medical conditions right from their homes, allowing for timely interventions when needed without frequent hospital visits. This is paramount for chronic disease management, postoperative care, and elderly patients. 

Backed by IoT devices, patients can recover at home under medical supervision via remote monitoring, significantly reducing hospital readmissions. In turn, This lowers healthcare costs and improves patient comfort and satisfaction. Since IoT also supports data collection, it can lead to better clinical decision-making and operational efficiency for healthcare organizations. It’s a win-win. 

What’s more, the integration of IoT with blockchain technology further improves security and privacy. Platforms like BurstIQ facilitate the sharing and usage of medical data securely. Using blockchain, healthcare providers can share sensitive information reliably and with ease. This helps them streamline operations while guaranteeing all involved parties have accurate and up-to-date data.

How Is IoT Used in Healthcare?

With more and more medical practitioners and hospitals adopting IoT, we are witnessing a new and improved healthcare system. How? Here are just some of the applications of IoT within the sector:

IoT Vulnerabilities in Healthcare

While IoT brings forth numerous benefits in healthcare, it also introduces significant vulnerabilities that we must address. One of the primary concerns involves the security of patient data. Connected medical devices often transmit sensitive information across networks, making them potential cyber-attack targets.

Additionally, many healthcare IoT devices do not feature robust security measures. This lack of security can encompass insufficient encryption, default passwords that users rarely change, and outdated software. Such weaknesses not only jeopardize patient data but can also threaten the functionality of critical medical devices.

Moreover, the complexity of interconnected systems can introduce vulnerabilities. The integration of multiple devices from different manufacturers into a single network can lead to inconsistencies in security protocols, creating gaps that attackers might exploit.

Addressing these vulnerabilities requires a multi-faceted approach: enforcing stringent security measures, regular updates and patches, and comprehensive training for healthcare professionals on best practices in IoT security.

IoT in Healthcare: Key Takeaways

Healthcare providers should seize the opportunities presented by IoT and blockchain to transform patient care and operational processes. The journey toward adopting these technologies begins with a strategic approach to implementation and a commitment to continuous improvement.

The shift towards skills-based hiring: A new era of talent acquisition

In today’s fast-evolving job market, there’s a growing trend towards skills-based hiring, which places a stronger focus on a candidate’s practical abilities rather than traditional qualifications like degrees or titles. This shift is fundamentally changing how companies approach recruitment, resulting in more dynamic and diverse workforces.

Organizations are increasingly recognizing that skills-based hiring can lead to better job performance, role fit, and inclusivity, which is driving widespread adoption of this model.

What is skills-based hiring?

Skills-based hiring is a recruitment strategy where employers focus on a candidate’s specific skills and competencies rather than their formal education or past job titles. For instance, companies may prioritize technical skills, such as proficiency in certain programming languages or software, or soft skills like communication and problem-solving, over traditional criteria like a four-year degree. As noted by SHL, this approach allows companies to uncover hidden talent and focus on candidates’ potential, helping organizations foster diversity, equity, and inclusion.

Why skills-based hiring is gaining popularity

  1. Access to a wider talent pool
    Traditional hiring methods often exclude individuals who may not have formal degrees but possess valuable skills. By adopting skills-based hiring, companies can tap into non-traditional talent pools, including self-taught professionals and those from different socio-economic backgrounds. As Workable reports, nearly 45% of companies in 2024 are expected to drop degree requirements for many roles.
  2. Improved role fit and performance
    Skills-based hiring often leads to a better match between the candidate and the job. Focusing on specific, measurable skills means that employees are more likely to succeed in their roles from day one. According to BCG, hiring based on skills is five times more likely to predict job performance than hiring based solely on degrees. By assessing candidates based on real-world competencies, employers can ensure a higher level of job readiness and productivity.
  3. Fostering lifelong learning and agility
    As companies face rapid technological changes, employees need to continuously upskill to remain relevant. A skills-based approach promotes a culture of lifelong learning, encouraging employees to focus on acquiring new competencies rather than relying on outdated credentials. This mindset aligns with the needs of industries such as IT and digital marketing, where practical skills and staying current with trends are crucial .
  4. Reducing bias and increasing diversity
    Traditional hiring processes can unintentionally reinforce biases related to education or socio-economic background. By shifting the focus to skills, companies can reduce these biases, offering more opportunities to underrepresented groups. According to SHL, a skills-based model promotes inclusivity by leveling the playing field, making it easier for companies to create a diverse workforce.

The challenges of implementing skills-based hiring

While the benefits of this approach are clear, there are several challenges that companies must navigate when adopting skills-based hiring practices.

  1. Defining clear skills criteria
    One of the main challenges is defining the precise skills required for each role. Companies must shift from focusing on traditional job descriptions to crafting skills-based profiles that clearly outline the necessary competencies.
  2. Effective skills assessment
    Assessing a candidate’s skills is often more complex than verifying their educational background. Companies must rely on practical assessments, such as tests or simulations, to evaluate real-world capabilities. For example, Boeing created an apprenticeship program for cybersecurity roles that doesn’t require a degree but emphasizes hands-on learning and skill development (
    McKinsey & Company) (BCG Global).
  3. Cultural change within organizations
    Shifting from a qualifications-based hiring approach to one focused on skills may require a significant cultural change. Long-standing hiring practices can be difficult to overhaul, and companies must invest in training hiring managers and redesigning recruitment processes to fully embrace skills-based assessments.

How companies can make the shift

  1. Invest in skills assessment tools
    Organizations need reliable tools to accurately assess candidates’ skills. Platforms offering practical evaluations, coding challenges, or case studies can help measure relevant abilities in a fair and transparent manner. As SHL highlights, using data-driven assessments allows companies to objectively evaluate competencies, improving hiring outcomes.
  2. Promote upskilling and internal mobility
    Fostering a culture of continuous learning is essential for the future workforce. Companies that encourage employees to reskill and grow within the organization can fill talent gaps internally. BCG notes that employees hired through skills-based hiring often experience longer tenures and are promoted at rates similar to those hired based on degrees.

How do we see it?

The shift toward skills-based hiring is more than just a trend; it represents a fundamental change in how organizations view talent acquisition. As businesses prioritize practical skills and competencies over traditional qualifications, they can build more dynamic, diverse, and high-performing teams. While there are challenges, including defining clear skills criteria and developing effective assessments, the long-term benefits of this approach make it a valuable strategy for future-proofing the workforce.

This approach is not only more inclusive and adaptable but also positions companies to better meet the demands of a rapidly changing job market. As SHL, BCG, McKinsey&Company and other industry leaders have demonstrated, skills-based hiring is key to unlocking hidden talent and ensuring long-term organizational success (McKinsey & Company).
