Introduction
Envisaging the public health workforce shortage among healthcare providers as a gradual trend that is undermining the reach and quality of healthcare. Healthcare professionals are an integral part of implementing disease prevention and control interventions that can ensure community safety (Loewenson et al., 2020). Their skills are deployed across a broad spectrum of activities ranging from disease surveillance and health promotion to policy formation and program institutions to manage public health issues.
Additionally, the shortage of health workers contributes to public health agencies’ inability to provide necessary services (Lisa et al., 2022). Such a workforce shortage compromises the effectiveness of public health activities, making healthcare access disparities worse and extending health inequality to everyone. The following paper examines the impact of the workforce shortage on a range of crucial public health issues.
The Magnitude of the Shortage
The shortage of public health workers per capita has increasingly become a significant problem, with the recent trend pointing to a decrease. There has been a scarcity of specific professions whose roles are fundamental to public health agencies, including public health nurses (Al Mohajer, 2023). The absence of experienced personnel, particularly in such a key position, may severely limit public health agencies’ ability to respond efficiently to emergencies and other challenges. The limited number of public health nurses remains a common problem, and these health specialists play a key role in delivering health care services and health education to communities.
As projected by Lisa et al. (2022), more registered nurse jobs will be required in the USA than in any other profession by 2022. The author further suggests that more than 275,000 nurses will need to be added to the United States workforce between 2020 and 2030 (Lisa et al., 2022). Their employment opportunities are likely to double (9%) between 2016 and 2026, compared with other occupations (Lisa et al., 2022). Therefore, these statistics indicate that the health care workforce shortage is likely to persist.
The public health workforce gap exists at the state and national levels. According to NurseJournal Staff (2023), nationally, 3,072,670 employed nurses serve a population of 333,287,557 individuals. This implies that there are 9 nurses per 1,000 individuals.
In Utah, the problem persists, as the average number of nurses serving 1,000 individuals is 6. A similar trend can be observed in Georgia, where 7 nurses are expected to provide health services for every 1,000 individuals (NurseJournal Staff, 2023). These figures reveal a growing shortage of healthcare workers in the United States.
Factors Contributing to Shortage
The workforce shortage in public health agencies is a profound phenomenon shaped by interconnected factors. Identifying the root causes behind these factors is an imperative step to solving this pivotal challenge. The American population is aging, with baby boomers entering a phase of life that requires greater health care needs. In the United States, the number of people aged 65 and older is currently at its highest level (Lisa et al., 2022).
By 2029, the entire baby boomer cohort will have retired, resulting in a73% increase in the number of seniors aged 65 (Lisa et al., 2022). According to the World Health Organization (2020a), the need for healthcare services grows as the population ages. The reality is that older people are more likely to have multiple diseases and comorbidities that necessitate treatment rather than just one. Therefore, this increases the pressure on healthcare systems that are likely to have limited staff.
In the realm of public health agencies, inadequate funding leads to constrained budgets, which, in turn, result in insufficient funds for hiring, training, and retaining quality professionals. According to Al Mohajer (2023), adequate financing is the backbone of any healthcare agency. Without it, the agencies are unable to provide affordable health benefits, professional networks, and other baseline retention mechanisms. This financial barrier reduces the number of people pursuing careers in public health and the number of qualified candidates. Consequently, it contributes to the workforce shortage, which aggravates the problem.
Moreover, public health agencies might be demotivated and struggle to retain and recruit skilled professionals, as it is hard to offer salaries below those in other healthcare sectors. The unavailability of competitive salaries, which indicate inadequate compensation, has done little to encourage people to choose a public health career and remain in it long-term (Colvin et al., 2021). As older employees seek highly paid roles in other parts of the job market and new graduates choose industries with higher salaries, the pipeline of workers in public health narrows, leading to a shortage of suitable personnel.
The retirement of veteran public workers in government agencies forms a break in knowledge, expertise, and administration within the workforce. According to Lisa et al. (2022), the retirement of experienced workers from the field results in a loss of expertise and mentorship opportunities, which are required for the next generation of public health workers to develop. Without succession planning and strategies to transfer their knowledge to junior workers, the gap in the outlined skills widens, leaving critical jobs unfilled.
Furthermore, limited training and educational programs, and a shortage of low-skilled personnel to address public health issues, create labor force shortages. Shamsi and Peyravi (2020) note that limited access to high-quality training and preparation for the future of public health workers creates obstacles to building a prospective workforce. Due to insufficient numbers of graduates entering the field to meet the demand for highly trained professionals, public health agencies often face a shortage of specialized health educator positions.
Additionally, a chronic deficit of progression ladders within the structures of public health institutions may lead to a workforce shortage. If healthcare workers feel they have very limited room for personal growth, they are more likely to leave, contributing to high turnover and labor shortages (McPake et al., 2024). If there is no clear promotion and contribution acknowledgment for the most capable people, the field may experience a lack of engagement and eventually lose several highly trained professionals.
Workforce burnout is a key problem driving an acute shortage of public health professionals. According to Lisa et al. (2022), public health workers may have heavy workloads, be understaffed, and have limited resources. Therefore, they might be under immense pressure, which may, in the long run, lead to physical and emotional exhaustion and increased risk of job dissatisfaction and feelings of depersonalization. Such significant burnout among current staff can also lead to higher turnover rates as individuals seek positions with better work-life balance and support services (Lisa et al., 2022). Moreover, the workforce shortage can be worsened by burnout, as strained, overloaded employees may not be able to provide the quality of care they would when not stressed.
The problem of having a diverse workforce in public health agencies can also exacerbate workforce shortages. Deterrents such as geographic barriers, poor workplace management culture, and policies that do not prioritize diversity can be obstacles to attracting and retaining competent employees (Lisa et al., 2022). For example, if some regions of the country struggle to attract qualified employees due to limited job opportunities, insufficient amenities, or inadequate support services, this can intensify the workforce problem in those areas.
Moreover, workplace cultural issues, such as discrimination, diversity shortages, or inappropriate leadership, may be contributing to the shortage of public health workers (Lock & Carrieri, 2022). Without comprehensive policies that foster a culture of acceptance and support for employees from multicultural backgrounds, public health agencies may struggle to sustain a diverse talent pool, thereby exacerbating workforce shortages.
Impact on Service Delivery
A limited number of public health workers can negatively impact service delivery. A shortage of the public health workforce could negatively affect the health services people seek. The shortage of a sufficient workforce to deliver essential services could result in increased waiting times and delayed access to care (Lee et al., 2020). This aspect often becomes challenging for patients who need urgent medical care or routine checkups, and delays in accessing medical care can make the patient’s health condition deteriorate.
Workforce scarcity may lead to public health agencies’ inability to maintain the standard of care the community needs at the required level (Lee et al., 2020). Work stress is one of the reasons employees may experience burnout, which can lead to poor patient care or a concerned attitude towards patients (Lisa et al., 2022). Furthermore, a shortage of skilled workers to handle a large number of cases or to respond quickly to emergencies will reduce the quality of care offered.
Health workforce shortages might fuel disparities in healthcare coverage, most evident in underserved and rural communities. Such an unequal distribution of public health services intensifies existing health disparities. This facet results in communities with low incomes and a high risk of limited access to healthcare resources due to insufficient providers or a scarcity of equipment (Asamani et al., 2021). This issue will likely continue to limit screening, treatment, and health promotion activities for people living in underserved areas, thereby increasing the likelihood of worse health outcomes and wider healthcare gaps.
Public Health Outcomes
The shortage of staff in public health agencies ripples through the entire public health system, affecting expected outcomes. A shortage of public health workers often hinders efforts to prevent disease at the individual and population levels (Malakoane et al., 2020). Public health institutions provide the public with knowledge about health risks and encourage people to adopt preventive measures. Insufficient personnel create hitches in public health communication, fewer preventive measures are provided, and a limited ability to respond to outbreaks or new health threats.
Consequently, the overall performance of disease prevention activities would decline, leading to higher rates of preventable diseases and suboptimal health outcomes for the community. Public health agencies are obligated to manage crises during natural disasters and disease outbreaks (Wilder-Smith & Osman, 2020). Insufficient human resources can delay the deployment of emergency services, the implementation of containment plans, and the distribution of important information to the public (Malakoane et al., 2020). This is particularly hazardous in emergencies, where urgent action can determine whether an event causes serious injuries or saves lives.
Community health promotion programs are tools aimed at addressing root health inequities, advocating for community-level healthy behaviors, and creating a healthier population. Public health officials craft and implement these health promotion programs, such as nutrition programs, physical activity campaigns, and smoking cessation services (Malakoane et al., 2020).
A shortage of the workforce can hinder the organization from bringing communities together, identifying strategic interventions, and sustaining the campaigns in the long run (Leider et al., 2023). Consequently, those populations who have low income can face roadblocks in obtaining health resources, preventive care, and better health lifestyles, which worsen the health inequalities among various disadvantaged groups within the society.
Policy Implications
Addressing staffing issues in public health departments is a major challenge that warrants a well-designed policy intervention. A policy approach that combines retention and recruitment to solve the public health agency workforce shortage must be in place (Shamsi & Peyravi, 2020). This solution can be achieved by recruiting talented individuals through competitive remuneration and by focusing on worker welfare programs. It includes providing training and seminars to the public health staff and hiring public health professionals to work for the agencies (Sparer & Brown, 2023). Policies that focus on employee well-being, career advancement, and recognition will promote the retention of the existing workforce and appeal to professionals of the current generation.
Another important policy option is investing in workforce development programs that not only improve the capacity of existing public health workers but also broaden their skill set. This aspect may include funding for training programs, ongoing education programs, leadership development, and skills classes focused on a particular area. By investing in the personal development of public health employees, policymakers will ensure a workforce remains competent, adaptable, and equipped with the tools needed to meet public health challenges (World Health Organization, 2020b).
Public health agencies must be creative in meeting their workforce’s needs while also providing the best and safest care for patients. A work environment that engages and encourages public health workers is essential to replenishing and sustaining the workforce (Lisa et al., 2022). Empowering jobs in staffing ratio decisions based on high volume and acuity levels will reduce burnout.
Collaboration with educational organizations is essential to addressing public health service shortages within agencies. Educators can collaborate with schools, public health agencies, universities, and training programs to align curricula with workforce needs (Manzini et al., 2020). Implementing pipelines for recruiting new talent and expanding opportunities for practical learning will help improve the situation. Policymakers ought to forge partnerships with academic institutions, thereby helping public health professionals become more competent, close skill gaps, and promote a seamless transition from education to practice (Sparer & Brown, 2023).
Such wide-ranging policy implications help policymakers better understand the multifaceted strategies these agencies need to address this workforce shortage challenge adequately. Policymakers could pave the way for a capable, robust public health workforce prepared to address a wide range of community health challenges (Sparer & Brown, 2023). The workforce can be achieved by prioritizing efforts to attract and retain healthcare professionals, investing in workforce development, and collaborating with educational institutions.
Conclusion
Public health agencies’ workforce shortage undermines the quality and accessibility of health services, as well as the health of people and society. The problem manifests in many ways, including an aging population, budget deficits, low wages, ineffective training programs, the retirement of experienced workers, and workplace challenges.
Shortages can make it difficult for patients to wait longer in the hospital, degrade treatment quality, increase stress and burnout among employees, create disparities in health insurance coverage, and impede disease prevention programs. To solve this problem, it is key to have policies that account for the recruitment, retention, and development of public health workers, and to work closely with educational institutions. By addressing those obstacles, public health agencies can build a durable, viable workforce to manage future health challenges better and improve population health outcomes.
