In many countries, people facing limitations in activities of daily living (ADL) and in instrumental activities of daily living (IADL) may not always receive sufficient formal long-term care (LTC) support. Among people aged 65 and over, across 22 European countries, half of individuals living at home with at least one ADL or IADL limitation reported that they did not receive sufficient formal or informal LTC support, illustrating the longstanding difficulties the LTC sector is facing in meeting demands for care (OECD, 2023[25]). Many countries in South and Southeast Asian countries are experiencing a shortage of health and care workers trained in geriatric care, coupled with inadequate healthcare infrastructure, particularly in rural areas. For instance, in India, medical students receive only one to two weeks of geriatric training, which constitutes less than 1% of their total medical education (NITI Aayog, 2024[37]). Social isolation and economic insecurity among older adults, especially those lacking access to pensions or adequate health insurance, further exacerbate the situation (ADB, 2024[38]).
Training of LTC workers helps to increase access to formal job opportunities in the healthcare sector. Although LTC jobs can be more complex than often portrayed, educational and training requirements for personal care workers are low. In fact, many countries do not require that personal care workers hold a minimum education level, and this despite the fact that mismatches in training and skills – such as specific geriatric training, health monitoring and care co‑ordination – can have a negative impact on the quality of care provided. Among countries that do, the requirement varies from vocational training (Hungary, Latvia, Luxembourg, the Netherlands) to a high school certificate (Belgium and Sweden) or a technical qualification after high school (Malta and Estonia). Very few countries (Canada, Denmark, Germany and Korea) have developed a career structure for LTC workers. This situation is aggravated by the fact that the LTC workforce in the OECD is often foreign-born (22% of employment) and working informally (OECD, 2020[39]). Flexible career pathways in healthcare can help address this issue by facilitating the rapid upskilling of health and care workers to meet the increasing demand for elder care services. By providing specialised training in geriatrics, chronic disease management and home‑based care, flexible pathways can assist countries in ensuring a stable supply of health and care professionals equipped to serve ageing populations, particularly in long-term care. Targeted training and innovative programmes can expand the health and care workforce and enhance care for the elderly. Further, after years of practice, many LTC workers in both the informal and formal sectors gain valuable skills. Recognising prior learning, along with additional training, can open up better career opportunities for formal workers and help informal workers transition into formal LTC jobs.
In the United Kingdom, the Skills for Care workforce planning body has launched the Care Workforce Pathway for Adult Social Care, which seeks to develop the first pathway for staff working in care roles (Skills for Care, 2024[40]). The initiative maps role categories in the care sector with definitions of behaviour, knowledge and skills expected for each role category. This sets the blueprint for identifying the skills and knowledges needed for the many different care roles. Flexible learning opportunities are key in addressing the skill shortages in the care sector, as many adults working in this sector face a multitude of barriers to participating in training.
In Australia, all continuous training programmes for LTC workers are sponsored by government’s funding. In addition, following the Aged Care Workforce Strategy, the Aged Services Industry Reference Committee started an examination process to reform the national training package qualifications and skill sets needed for LTC, as well as new approaches to career structuring and progression in the sector. In 2023, the My Aged Care Learning Strategy 2023 was released. This strategy outlines the required capabilities and minimum training to access to the aged care system and adopts a blended approach to learning, including on-line training, on-the‑job learning and evaluation by experienced workplace trainers and managers (Department of Health and Aged Care, 2023[41]).
In Austria, where a technical degree after high school is required for personal care workers and a Bachelor’s degree is required for nurses working in LTC, training for LTC workers is fully covered by governments and employers. Training can be provided during working time, and the ten weeks of education required to participate in the LTC workforce can be provided on-site, in schools or in universities (OECD, 2020[39]).
Germany has provided funds for education and redesign of degrees. School fees have been abolished in nursing education and a new legislation merged specialised nursing systems (general, geriatric and paediatric) allowing for more flexibility (Federal Ministry of Health, 2023[42]). Regarding specific measures for geriatric care, the education and training initiative for elderly care implemented between 2012 and 2015 extended options for shortening training when applicants have relevant knowledge and contributed to an increase in the number of trainees in geriatric care.
In Iceland, where no statutory minimum requirements exist for personal care workers, they can receive education or training specific to LTC. Courses take 2‑3 months, part time alongside work. Short training is mostly covered by unions or employers, and workers are often allowed to take part of it within working time. For social care workers, formal LTC education usually takes 2 years; for nurse aides (for which a Bachelor’s degree is required), it usually takes 3‑4 years (OECD, 2020[39]).
In the Philippines, the Technical Education and Skills Development Authority (TESDA) has developed the Caregiving (Elderly) NC II programme which is designed to meet the growing demand for skilled caregivers, addressing the challenges posed by an ageing population.6 The programme offers a structured and flexible pathway for individuals aspiring to enter the caregiving profession. The programme is part of TESDA’s broader strategy to enhance the workforce by providing nationally recognised certifications and skills training aligned with global standards. The Caregiving (Elderly) NC II programme equips students with the competencies necessary to provide care and support for the elderly in a variety of contexts, including private care, hospitals, clinics and other healthcare facilities. The programme encompasses both theoretical instruction and hands-on training, ensuring that graduates can effectively apply their skills in real-world settings.
The Caregiving (Elderly) NC II programme, delivered through TESDA’s accredited training centres across the Philippines, combines classroom-based instruction with supervised practical training to prepare individuals for professional caregiving roles. For those with prior caregiving experience, TESDA offers Recognition of Prior Learning (RPL), enabling candidates to have their skills assessed through practical demonstrations and interviews. This process allows them to gain certification without redundant training, saving time and resources. For individuals requiring additional training, TESDA provides modular learning options, ensuring they complete only the components necessary to complement their existing knowledge. Graduates of the programme receive the Caregiving (Elderly) NC II certificate, recognised both domestically and internationally, opening doors to employment in various settings, including private caregiving, hospitals, clinics, and residential care facilities. Beyond immediate employment, TESDA facilitates pathways for career progression, allowing certified caregivers to transition to related careers in healthcare or pursue advanced qualifications. In 2023, the programme recorded a total of 1 788 enrolments and 1 273 graduates, underscoring its critical role in addressing the growing demand for eldercare services amidst the country’s rapidly ageing population.7
In response to its rapidly ageing population, Thailand has developed a Community-Based Long-Term Care (LTC) Programme, aimed at providing comprehensive care for elderly individuals who are homebound or bedridden (ADB, 2020[43]). Launched in 2016, the programme seeks to improve the quality of life for older adults by offering co‑ordinated health and social services. Managed by local administrative organisations from the health and social services sectors, with support from the Ministry of Public Health, the programme establishes a framework for integrating care within the community. Central to the LTC programme are CHWs, who undergo 70 hours of training in areas such as chronic disease management, health promotion and mental health care to become community caregivers. Some CHWs are paid professionals, while others serve as volunteers. They visit elderly individuals in their homes, providing support for daily living activities, medical care and rehabilitation services. Depending on the individual’s needs, in-home care may range from two to eight hours per week.
In addition, the programme has established a new role for care managers, typically nurses or social workers, who play a key role in the initiative by assessing the health and social needs of elderly beneficiaries and co‑ordinating care plans. These managers undergo 70 hours of training focussed on ageing, the rights of older people, the role of a care manager and basic care management practices. They work with both the families of the elderly and health and care professionals to ensure that care is personalised, effectively monitored. Care managers are also responsible to manage and monitor the performance of five to ten caregivers.
Funded through the Universal Coverage Scheme (UCS), Thailand’s LTC programme represents a significant step in addressing the healthcare needs of its ageing population. By emphasising community-driven care and providing formalised training for caregivers, the programme not only supports elderly individuals in ageing at home but also offers a structured career path for those aspiring to enter the caregiving profession. By 2018, the programme had expanded to cover 5 639 out of 7 776 subdistricts, aiming to serve 193 000 people. As Thailand continues to expand and refine the programme, it may serve as a model for other Southeast Asian countries facing similar demographic shifts.
Similarly to long-term care, community health workers often face large levels of informality in the labour market yet could play an important role in addressing workforce shortages. Zimbabwe faces a persistent human resource for health (HRH) crisis marked by shortages, maldistribution, and attrition of health professionals. The challenges are driven by migration of doctors and nurses, poor remuneration, inadequate supervision, and disparities between rural and urban postings, which collectively undermine the country’s ability to deliver equitable services (ReBUILD Consortium, 2015[44]). Despite the launch of the Health Workforce Strategy 2023‑2030, which aims to scale up annual training outputs to 7 000, create 32 000 new positions, and integrate community health workers (CHWs) into the system, Zimbabwe continues to grapple with significant gaps (WHO Africa, 2024[45]). Within this constrained context, informal providers such as Village Health Workers (VHWs) or CHWs play an indispensable role in sustaining primary healthcare delivery. Established in the 1980s, the VHW programme provided community-level services in health promotion, prevention, minor treatment, and surveillance, particularly in underserved rural areas (CHW Central, 2018[46]). However, these workers often lack consistent remuneration, standardised training, and adequate supervision, leaving their contributions under-recognised and vulnerable to systemic neglect (Munyai, Mudau and Mashau, 2025[47]).
The reliance on informal providers reflects broader structural weaknesses, where up to 60% of Zimbabwe’s workforce operates informally, acquiring skills outside regulated systems (Medina, Jonelis and Cangul, 2017[48]). In health, this results in large numbers of providers working without clear credentialing, regulated scopes of practice, or pathways for professional advancement, and potentially without the competence to do the job. While VHWs and CHWs are integral to bridging service gaps, they remain outside the authority of professional councils that license and regulate doctors, nurses, and allied professionals (ReBUILD Consortium, 2015[44]). Recently, the government signalled a shift by announcing the absorption of 22 000 CHWs into the civil service by the end of 2025, with a longer-term goal of doubling their numbers to 40 000 by 2030 (Frontline Media, 2025[49]). This represents a move toward formal recognition, yet the absence of flexible credentialing mechanisms limits opportunities for informal providers to transition into more advanced roles, such as health assistants or technicians.
Creating flexible pathways for informal providers could significantly strengthen Zimbabwe’s health workforce. Modular training and bridging courses that acknowledge prior informal experience would allow VHWs to acquire credentials and progress into semi-formal or formal cadres. Standardised curricula, supervision, and regulation would improve the quality and safety of care, while official recognition and remuneration would enhance motivation and retention. Such pathways would also deliver cost-efficient expansion of service coverage, particularly in rural areas where physician shortages are acute. However, these reforms require regulatory innovation, investment in training infrastructure, and integration into broader HRH planning to avoid perpetuating a two‑tier system. Zimbabwe could move closer to achieving universal health coverage while simultaneously addressing its HRH crisis by formalising and professionalising the role of VHWs and other informal providers.
The formalisation of previously informal healthcare provision is enabling workers in Tanzania to enter formal health professions. The Accredited Drug Dispensing Outlets (ADDOs) represent an innovative yet hybrid approach to strengthening Tanzania’s pharmaceutical workforce. Although considered informal, ADDOs operate under a semi-formal framework, as dispensers receive structured training and certification before being licensed to operate. They were first introduced to expand access to essential medicines through community pharmacies known as Duka la Dawa Muhimu (DLDM), with a particular focus on underserved rural and peri‑urban populations (Rutta et al., 2009[50]; Pharmacy Council, 2015[51]).
Over time, ADDOs have evolved into a flexible pathway into formal health professions, enabling thousands of individuals – many of whom would not otherwise enter the health sector – to contribute to service delivery. To date, Tanzania has established more than 9 000 accredited medicine outlets staffed by over 19 000 trained dispensers, significantly increasing coverage of pharmaceutical services across the country (Pharmacy Council, 2015[51]). Their contribution has been notable in areas such as antimicrobial stewardship, where ADDOs have played a role in guiding appropriate medicine use and expanding health literacy (Rutta et al., 2009[50]). However, sustainability challenges remain. Ensuring consistent quality assurance, regulatory oversight, and professional standards has proven difficult given the scale and diversity of ADDOs. Variations in adherence to dispensing guidelines, limited supervision, and the commercial pressures faced by operators can compromise service quality. Long-term sustainability therefore depends on stronger regulatory mechanisms, ongoing professional development for dispensers, and better integration of ADDOs into the formal health system (Pharmacy Council, 2015[51]) and institutionalisation through existing training frameworks including the Technical and Vocational Education and Training Institutions.
In summary, while ADDOs have demonstrated how non-traditional pathways can expand healthcare access and serve as stepping-stones into formal professions, their sustainability hinges on balancing access, quality, and regulation within Tanzania’s broader health system.
