ABSTRACT The COVID- 19 pandemic highlights the implications of chronic underinvestment in health workforce development,particularly in resource- constrained health systems.Inadequate health workforce diversity, insufficient training and remuneration, and limited support and protection reduce health system capacity to equitably maintain health service delivery while meeting urgent health emergency demands. Applying the Health Worker Life Cycle Approach provides a useful conceptual framework that adapts a health labour market approach to outline key areas and recommendations for health workforce investmentbuilding, managing and optimising-to systematically meet the needs of health workers and the systems they support. It also emphasises the importance of protecting the workforce as a cross- cutting investment, which is especially important in a health crisis like COVID- 19.While the global pandemic has spurred intermittent health workforce investments required to immediately respond to COVID- 19, applying this ‘lifecycle approach’ to guide policy implementation and financing interventions is critical to centering health workers as stewards of health systems,thus strengthening resilience to public health threats,sustainably responding to community needs and providing more equitable, patient- centred care.

lNTRODUCTlON

As COVID- 19 cases push health systems to their limits, the world’s attention has turned towards health workers. Around the globe,health workers are praised for their heroic efforts to control the pandemic and provide essential health services. However, health workers need more than recognition and applause. Highlighted by the WHO’s designation of 2021 as the ‘Year of Health and Care Workers’ and the 74th World Health Assembly’s resolution to protect and safeguard the health and care workforce, health workers need tangible action through policy change and increased investments to build their capacity and support their wellness, psychosocial care, safety and security.12

Health workers are crucial for functional health systems.3However, workforce investments are routinely undermined by inadequate domestic health financing coupled by fragmented investments across vertical initiatives, which impede comprehensive health workforce training, recruitment and deployment, performance management and retention. In 2013, the WHO published a health labour market framework to organise and analyse these issues.4Its Global Health Workforce 2030 Strategy underscores the need for increased health workforce investments at scale, forewarning that migration and increased healthcare demands by an ageing global population would further exacerbate the already severe health workforce shortage, then estimated to reach 18 million by 2030.5Furthermore, the formidable prepandemic estimate of a 10- to- 1 return on health workforce investments is now likely even greater.6The COVID- 19 pandemic has made clear that investing in health workers is a matter of life or death.

The pandemic has set a profound precedent for the intrinsic value of health workers to health system resilience (the ability to absorb,adapt and transform to changing conditions) and to global health security. Health workers are essential for delivering routine services, educating communities, combatting dangerous misinformation, building vaccine confidence and facilitating positive behaviour change to improve the COVID- 19 response.With up to 180 000 COVID- 19 related health worker deaths estimated worldwide, now is the critical—but fleeting—moment for countries to prioritise strategic health workforce investments to effectively respond to COVID- 19 while building more sustainable health systems for the future.7

HEALTH WORKER LlFE CYCLE

Figure 1 HRH2030 Health Worker Life Cycle approach in COVID- 19 and beyond.

Recognising that previous health workforce frameworks focus on systems at the macro level across health, education and labour sectors,48the United States Agency for International Developmentfunded Human Resources for Health in 2030 (HRH2030)Program developed the ‘Health Worker Life Cycle Approach’ (figure 1) to illustrate goals for health workforce investments based on a health worker’s journey through the health system. It outlines novel, personcentric interventions to build, manage and optimise human resources for health (HRH) to ensure health workers reach their fullest potential at key stages of their development and career progression.

The Health Worker Life Cycle Approach considers three phases: building, managing and optimising. For building,it first begins at secondary school graduation, proceeds to enrolment, and moves to completion of quality health professional training and education. Second, it considers management and support for certified professionals seeking fairly remunerated, fulfilling jobs to perform well and advance their careers with opportunities for growth.Third, it highlights the sharing of roles and tasks and other methods to optimise the health workforce within a high- performing health system. Continual learning,support and protections for all health workers are paramount across all stages of the life cycle.

On a technical level, this framework serves as a heuristic tool for decision makers to identify and address important gaps in existing investments and financing or to coordinate HRH investments within and across health systems.9–11On a normative level, this approach to HRH planning offers a holistic way to design, implement and communicate interventions focused on advancing the health workforce into one that is motivated, available,accessible, integrated and fit to combat emerging threats and achieve health for all.

This paper represents a synthesis of health workforce policy and practice issues, rather than originating from a structured research process. To this extent, we outline calls to action through our application of the life cycle approach to recommend strategic investments towards building, managing and optimising the health workforce,with key examples and lessons learnt from the ongoing COVID- 19 response.12In addition to alleviating immediate challenges exacerbated by COVID- 19, using the framework can contribute to improved health system efficiencies—such as workforce optimisation and improved resource allocation—as well as to economic stability and growth, resulting in greater equity and resilience.

BUlLD: DEVELOPlNG A SUSTAlNABLE HEALTH WORKFORCE

The limited quantity, diversity and distribution of trained health workers can inhibit a health system’s flexibility and adaptability when responding to a health emergency.13Many countries lack sufficient workforce capacity, nor have the means to train health workers in health safety protocols. For every $1 invested in COVID- 19 vaccine doses, an estimated $2.50 is needed to fund, train,equip, support and protect health workers.14Still, in urgent response to the pandemic, some countries rapidly bolstered their workforce by training community- based outreach workers, contact tracers and paramedical professionals, allowing new graduates to begin direct practice while encouraging retired medical workers to return to practice. Worldwide, more than one in four young people have been involved in some aspect of COVID- 19 related social activism, awareness campaign or supply distribution, demonstrating that health systems should further invest in youth.15

lntegrate positive youth development to promote health careers

Today’s youth are tomorrow’s health workforce. The health education sector can harness the global demographic dividend through investments in youth to expand and build a more diverse health workforce.16Health professional institutions (eg, vocational training schools)should consider: expanding health promotion and education curriculum in schools, integrating public health programming at science- based and science, technology,engineering and math (STEM) institutions, scaling up leadership and volunteer opportunities in community public health (eg, internships with health departments),cocreating healthy youth and adolescent initiatives and offering free advisory services for health careers. The health sector can recruit secondary school graduates to fill roles that require less time- intensive training (eg, educators, contact tracers and vaccinators) immediately, and then support them towards progressively advanced health professional training—including on- the- job certification programmes—to align with the future job market. Young professionals are needed to assume a range of health sector roles to bolster health informatics, social services,environmental health, pharmacy, laboratory and diverse public health functions, including agricultural extension for ‘One Health’ (a collaborative, multisectoral and transdisciplinary approach to achieve optimal health outcomes for people, animals, plants and their shared environment).17With a diverse skill mix, the health system can respond to health emergencies in a more comprehensive,inclusive and cross- sectoral manner.1819

Further diversify health workforce profiles and skills

To build a sustainable health workforce, HRH planners should account for population health needs, service delivery gaps and relevant skill requirements, including basic mental health and psychosocial support. Training and recruiting health workers from all communities(eg, geographic, socioeconomic, linguistic, gender and ability) can diversify the health workforce pipeline to promote accessible, trusted and person- centred health services and to improve service acceptability and equity.In addition to community- based and paramedical professionals, health workers with specialised skills, such as molecular biologists, genome scientists and health technology experts for telemedicine and geographic information system mapping, have been critical to the COVID- 19 response and emphasise the broad mix of health professionals required for resilient health systems.

lmprove quality and availability of health workforce education

Building health workforce quality is as important as quantity. Health workers must be properly trained for rapid delivery of effective, safe healthcare, especially in health emergencies. During COVID- 19, high- quality, responsive and flexible training systems to upskill health workers—for both preservice and in- service training—have been essential. Flexible, competency- based health professional learning models are key to promote interdisciplinary practices, enable task- sharing and coordinated care and support remote or virtual learning.20e- Learning platforms have been used to orient health workers on COVID-19, because they are virtual, safe, low- cost, and have wide reach. The WHO Academy deployed a multilingual e- learning mobile application to train health workers to detect, protect, respond to and manage COVID- 19.21The Philippines’ Department of Health (DOH) Academy, as of June 2021, has deployed 39 free eLearning courses and trained more than 18 000 health professionals through the platform.2223Furthermore, underused technical and vocational education training institutions can create alternative career pathways, fill gaps to professionalised or specialised roles and improve health training accessibility and affordability, especially in low- resource settings.24Analysis of health workforce skills gaps against population health trends should guide health workforce production.Planners should also assess and address the financial,gender, language and cultural barriers to training enrolment, so that health worker learning opportunities are accessible, inclusive, equitable, continual and responsive to health system needs.25

MANAGE: PLANNlNG, SUPPORTlNG AND MONlTORlNG THE HEALTH WORKFORCE

The global community has struggled to manage and protect the health workforce throughout the COVID- 19 pandemic—particularly in under- resourced settings—due to inadequate staffing, supplies and personal protective equipment (PPE).7More than 570 000 health workers were infected and 2500 killed by COVID- 19 across the Americas in just the first 6 months of the pandemic.26With 51% of healthcare professionals surveyed across 60 countries reportedly grappling with burnout, including nurses on the brink of ‘mass trauma’, ensuring comprehensive occupational safety and psychosocial support for health workers is vital.2728It is also critical to mitigate attrition due to burnout and impaired mental and physical health caused by poor working conditions, stigma and discrimination and violence towards health workers.

In addition, it is important to consider how men and women may experience a health emergency differently.COVID- 19 has exacerbated the economic stressors many women already face; women comprise 70% of the global health workforce, including unpaid and informal work totalling a staggering 2.35% of global gross domestic product (GDP).29The pandemic has increased reliance on women’s informal work in health without sufficient remuneration. Furthermore, PPE is often ill- fitting for women, increasing occupational risks.30

COVID- 19 has prioritised the need for broader improvements in data- driven management of health workers for effective planning, deployment, remuneration, performance support, retention, protection and safeguarding for the entire workforce. Foundational health workforce management investments implemented in response to COVID- 19—including assessment of workload pressures,motivation and strategic planning—should continue after the crisis abates.

Expand and sustain the job market

Across both public and private sectors, additional professional health jobs are needed for a more resilient health system. COVID- 19 has spurred public health innovations within traditionally non- health sectors—including enhanced professional roles for healthy behaviour change in private companies, data analytics for outbreak forecasting, and social services integration—suggesting the need for a multistakeholder, interdisciplinary approach to workforce development. COVID- 19 has demonstrated the value of community health workers (CHWs) and the need to further professionalise this workforce.10Countries should enhance policy reforms to ensure fair remuneration. Decent, safe, long- term work options are critical for young people who are underemployed due to the pandemic’s economic impacts.16Moreover, to protect job markets in under- resourced settings, migration management policies, ethical recruitment of health workers and enforcement of fair bilateral agreements in favour of country of origin should be put into place.31

lncrease interventions for health workforce protection,including mental health

Health systems must always protect health workers and safeguard their well- being. Enhanced policies and increased resources can provide safer working conditions and expand access to psychosocial support and mental health services for health workers and their families, building on lessons learnt during the COVID- 19 response.3233In Brazil, a mental health smartphone application has been successful in screening health workers for depression and anxiety while also promoting self- care and clinical support when needed.34Financial support, danger pay,and licenced, safe childcare can foster workforce resilience in future health emergencies.35All health workers should be prioritised for COVID- 19 vaccination and any future evidence- based health protections. This requires high- quality and real- time workforce data for strategic implementation, as exemplified by Indonesia.3637

Enhance health worker performance management

Health workers benefit from routine supervision, mentoring and performance feedback.38Therefore, performance management systems should use standardised performance metrics to promote quality standards and continued professional development, as done in Jordan.39Up- to- date data from human resource information systems (HRIS) can be used to respond to future health challenges, which may require rapid mobilisation of health workers across both public and private sectors,as exhibited in Senegal.40

OPTlMlSE: ENHANClNG, lNTEGRATlNG THE EXlSTlNG HEALTH WORKFORCE

COVID- 19 has drawn attention to striking gaps and inefficiencies in health systems operations, including processes that lead to suboptimal allocation and distribution of health workers. Major global health agendas (eg, global health security, universal health coverage, the ‘One Health’ approach), fragment investments and health workforce interventions.41Taking a health workforcefocused approach would promote equitable integration of both global health security and broader health systems strengthening efforts needed to achieve global health goals.42When hiring more health workers is not a shortterm option, increased performance and productivity of existing health workers through optimisation and greater efficiencies is imperative. With COVID- 19, health systems have needed to rapidly reconfigure health workforce staffing across facilities and communities. Adapting service delivery during the COVID- 19 pandemic has been critical to meet new demands, maintain the provision of essential services and protect patient and health worker safety.

Respond to workload pressures with flexible staffing and services

Short- term innovations to optimise health workers during COVID- 19 can improve workforce readiness to care for increased volumes of patients. These include rapidly back- filling frontline staff, planning for absenteeism, deploying staff across sectors, recruiting and fasttracking foreign- trained health personnel and trainees,formal HRH sharing across public and private sectors and allowing interjurisdictional mobility and licensure flexibilities. Comprehensive ‘work–life’ support—such as home support, housing, childcare subsidies and/or IT infrastructure for virtual care—can boost provider availability. Alternative deployments for health workers whose normal duties are temporarily suspended or for those with underlying health conditions, expanding and creating new roles as well as scaling up telehealth can also optimise the available health workforce, as done in Canada.43

lmprove evidence and efficiency of resource allocation and distribution at facility and community levels

Managers can use health workforce data from a robust HRIS to track workforce availability in real- time, allocate tasks or distribute staff more efficiently. During COVID-19, Indonesia and Taiwan successfully integrated health system data on health workforce, PPE, critical medications and vaccines, with geographic hotspots or gaps.44Robust data can support strategic, continuous staffing readjustments to meet service delivery demands; inform schedules and assignments; coordinate services across teams of facility and community- based workers; and support community- based monitoring. Additional health information investments can link data from the education sector on health professional graduates to inform coordinated policy approaches and address international supply and mobility of the health workforce during health emergencies.45

Adjust service delivery models for person-centred care

Optimal health worker skill mix, or staffing composition, should promote interprofessional, holistic, personcentred care. Multidisciplinary team- based services can promote task sharing and enhance efficiency in service delivery and coordination across community and facility settings, connecting community- based workers to the health system spectrum from primary healthcare to supply chain management.1046

COVID- 19 has demonstrated the importance of integrated service delivery and team- based care, including through the use of telehealth and digital applications to maintain services.47National governments, donors and policymakers should work to advance integrated service delivery by fostering alignment across major global health agendas and host country national strategies, particularly through delivery of primary healthcare services.4048Investments to reduce fragmentation in service delivery can help address future health threats such as climate change, antimicrobial resistance and pandemic influenza while delivering comprehensive care for all communities,especially those most underserved.4149Task sharing can be particularly effective among CHWs and can better support those disproportionately affected by COVID-19, based on biomedical, social and care priority needs.CHWs can distribute vaccines, care for patients with chronic COVID- 19 symptoms and deliver healthcare and behaviour change messages.5051

Offer gender-equitable, non-discriminatory working environments

Health workers cannot reach their full potential without a supportive and enabling environment. The pandemic is disproportionately affecting women; in addition to high rates of gender- based violence, gender inequities persist in health workforce leadership. Of the 70% female global health workforce, only 25% are in leadership roles, despite evidence that many women leaders have responded more inclusively to the COVID- 19 pandemic.5253Furthermore,recent attention to systemic inequities has unveiled greater awareness of health worker hardships.5455Investments in antiracist, non- discriminatory and progressive workplace policies that are health worker- led—including equitable and inclusive leadership programmes, genderappropriate PPE, integrated skills- development with cross- sector training and certification, and metrics and safeguards for transparency and accountability—are vital for health workers to thrive.

CONCLUSlON: WHERE DO WE GO FROM HERE?

COVID- 19 has exposed global health workforce gaps and brought forth the urgency of health system actors to invest in critically needed health worker policies,financing, training, care and protection. Alarmingly,in- country delivery gaps—often the result of inadequately supported health workforce—have become key bottlenecks in responding to the pandemic and preventing future public health threats.56Moving forward, principles underpinning our calls to action are to:

1. Expand the people- centred approach to the health workforce. As policymakers increasingly focus on person- centred health services, so too should they affirm their support towards a people- centred approach for those who deliver healthcare. This can bring attention to gaps across all phases of the health worker life cycle and lay a foundation for critical investments to address inefficiencies, which in turn promotes longterm sustainability of the health workforce beyond the COVID- 19 response.

2. Diversify and protect the health workforce. Stronger cross- sectoral coordination across interdisciplinary health system actors is needed to expand medical and paramedical profiles, broaden skill mix and enact policies and strategies to engage under- represented demographics in the future workforce, including women,youth and people who have been historically underrepresented in the health workforce. Access to flexible,competency- based learning platforms is a prerequisite for more efficient, equitable, evidence- based service delivery models that include task sharing, flexible staffing models and person- centred care.

3. Make lasting financial commitments and partnerships.The COVID- 19 pandemic serves as a powerful call to action for policymakers, donors and leaders to move towards meaningful investment in health workers, including fair remuneration and protection. We must leverage recent—and long overdue—momentum to support health workers. Leaders around the world must make stronger financial commitments and identify innovative financing and partnerships to achieve these recommendations.

As world leaders look to achieve universal health coverage, strengthen health systems, bolster global health security mechanisms, effectively respond to COVID- 19 and reach our global Sustainable Development Goals,they have an opportunity shift the paradigm from health worker gratitude and applause to concrete action. Greater strategic investments in the health workforce today will enhance the preparedness, response and resilience of our health systems tomorrow. If we remain complacent and unsupportive of HRH development or fail to deliver on our commitments to the brave stewards of our health systems, we will undoubtedly once again be woefully unprepared for the next emerging threat.
