Today’s Caribbean Current: Beyond Doctors and Nurses – Building the Full Health Workforce

Health workforce diversity is essential to building resilient healthcare systems. Yet when most people talk about the health workforce, the conversation almost always begins with doctors and nurses. That framing is understandable. They are the most visible professionals in the system. But modern healthcare depends on a far broader network of expertise. In fact, the World Health Organization defines the health workforce as all people engaged in actions whose primary intent is to enhance health. That definition intentionally extends beyond physicians and nurses to include pharmacists, laboratory professionals, rehabilitation specialists, public health professionals, community health workers, health managers, and many other roles that contribute to care delivery and system performance. Recognizing this broader definition matters, particularly as health systems become more complex.

A personal reflection on the workforce conversation

My own background sits somewhat outside the professions that people typically associate with healthcare. I am a health economist with training in bioengineering. Over the years, I have occasionally heard a familiar sentiment expressed in different ways:

“But you don’t take care of patients.”

In a narrow sense, that observation is correct. I am not providing bedside care. But modern healthcare depends on many professions that operate behind the scenes yet have a profound impact on patient outcomes. Health economists help systems determine how limited resources can produce the greatest possible health benefit. Engineers help design the devices, diagnostics, and systems that clinicians rely on every day. Health informaticians build the digital infrastructure that allows patient data to move safely between providers. Public health professionals help identify patterns of disease across entire populations. None of these roles replace clinicians. But without them, clinicians cannot work as effectively as they should.

The workforce behind the workforce

Research increasingly supports the importance of multidisciplinary and interprofessional teams in healthcare. Evidence reviews examining team-based primary care have found that expanding the mix of professionals involved in care delivery can improve coordination, strengthen outcomes, and allow systems to manage rising demand more effectively. This broader workforce includes several categories that often receive less public attention but are critical to health system performance.

Laboratory professionals ensure that diagnostic testing is accurate and reliable, enabling clinicians to make informed treatment decisions.

Pharmacists help ensure safe prescribing, medication management, and treatment adherence.

Rehabilitation professionals, such as physiotherapists and occupational therapists, help patients recover function and maintain quality of life after illness or injury.

Community health workers help bridge the gap between health systems and the communities they serve, improving access, continuity, and trust.

Health managers and administrators coordinate services, oversee operations, and ensure that systems function efficiently.

Each of these professions contributes to patient outcomes in ways that are sometimes invisible, but no less essential.

New roles for modern health systems

Healthcare is also becoming more technologically sophisticated, which is creating demand for new types of expertise.

Health informaticians design electronic health record systems and data infrastructure. Data scientists analyze population health patterns and system performance. Biomedical engineers maintain and manage medical equipment and diagnostic technologies. Digital health specialists design platforms that support telemedicine, remote monitoring, and integrated care. These professions may not stand at the bedside, but they are deeply connected to what happens there.

For example, a clinician’s ability to diagnose disease quickly may depend on laboratory systems functioning properly. Safe surgery may depend on biomedical engineers maintaining imaging equipment. Coordinated care may depend on digital systems that allow patient data to move securely between providers. Modern healthcare is increasingly a team effort that spans clinical, technical, and analytical expertise.

Technology is changing the workforce

Another factor shaping the future health workforce is the rapid development of digital technology and artificial intelligence. Recent analyses from McKinsey suggest that up to 30 percent of healthcare activities could be automated using existing technologies, particularly administrative tasks such as documentation, scheduling, and billing. Importantly, these technologies are expected to support clinicians rather than replace them, allowing professionals to spend more time on direct patient care.

At the same time, these technologies create demand for new types of expertise within the health system. Data analysts, AI specialists, health informaticians, cybersecurity experts, and digital health professionals are becoming increasingly important as health systems adopt more advanced technologies. Organizations such as the World Economic Forum and the OECD have also highlighted that future health systems will require a workforce capable of integrating technology, analyzing data, and managing increasingly complex digital environments. In other words, technology does not eliminate the need for people. It changes which skills are required and how teams work together.

Why this matters for the Caribbean

For small health systems like those across the Caribbean, this perspective is particularly important. If workforce planning focuses only on physicians and nurses, it risks overlooking other critical capabilities that determine whether systems can modernize, coordinate care effectively, and adopt new technologies safely. For example, expanding diagnostic services requires not only physicians but also laboratory scientists and technicians. Introducing new medical equipment requires biomedical engineers who can maintain and manage it. Building modern health information systems requires professionals trained in health informatics and digital infrastructure.

Similarly, strengthening prevention and primary care often depends heavily on community health workers, public health professionals, and allied health specialists who support patients outside hospital settings. Planning for the full workforce therefore means thinking carefully about the skill mix required across the entire health system—not simply counting the number of clinicians available.

Building the workforce we actually need

The implication for policymakers and health leaders is clear. A strong health workforce strategy must look beyond traditional professional boundaries and consider the full ecosystem of skills that support healthcare delivery. That means investing in training pipelines across multiple disciplines, strengthening workforce data and planning, and creating environments where multidisciplinary teams can collaborate effectively.

Doctors and nurses remain indispensable to healthcare. But they are not alone in carrying the system forward. The future of healthcare in the Caribbean will depend not only on how many clinicians we train and retain, but also on whether we recognize—and invest in—the full range of professionals who make modern health systems possible. Because ultimately, the workforce we choose to count shapes the workforce we choose to build.
