In general, vulnerable groups requiring particular attention and support include individuals with disabilities, migrants, the unemployed, older adults, orphans, and homeless individuals. Supporting these groups necessitates consideration of their unique needs and challenges and the implementation of innovative approaches aimed at integration, assistance, and social adaptation. The primary focus of this study is the analysis of social services aimed at supporting persons with disabilities and the unemployed; however, to provide a broader perspective, the research also examines other vulnerable groups, such as migrants, the elderly, and the homeless. This approach allows for a more comprehensive reflection of innovative practices in social work applied to various population categories and helps identify common trends in the provision of social services.

Individuals with disabilities face physical, social, and economic barriers. Supporting this group involves the development of individual rehabilitation programmes, which encompass medical services, vocational training, and employment assistance.² Furthermore, it is crucial to implement inclusive workplace policies that adapt work environments and provide support from colleagues. The establishment of day-care centres where individuals with disabilities can access therapy, engage in social interactions, and develop skills contributes to their social integration.

In the scholarly literature, the effectiveness of social services is often viewed not only through quantitative indicators but also within a broader framework of social outcomes. This perspective aligns with the widely recognised European “input-process-output-outcome” model, which suggests that the quality of social policy depends not only on legislative or organisational mechanisms but also on its capacity to promote social inclusion and improve the well-being of vulnerable groups. In this study, this theoretical approach is used merely as an analytical background, without emphasis on statistical measurement or quantitative evaluation.

Long-term unemployed individuals require comprehensive support to facilitate their reintegration into the labour market.³ Vocational training programmes, tailored to current market demands, enable them to acquire new skills. Equally important are psychological training sessions aimed at restoring motivation, self-confidence, and job-seeking skills. Young people entering the workforce should receive special attention, ensuring they have access to internships and mentorship.

Supporting vulnerable populations is a core aspect of social work across Europe. These groups frequently face challenges, including poverty, social isolation, discrimination, inadequate access to services, and physical or mental health issues. Key vulnerable groups include homeless individuals, who lack stable accommodation and often have limited access to medical, social, and psychological services. Social work interventions for this group typically involve temporary shelters, housing support, and social reintegration programmes.⁶ People with disabilities, whether physical, intellectual, or sensory impairments, frequently encounter barriers to education, employment, and social participation. Social workers develop individual support plans and advocate for inclusive environments to enhance their quality of life.¹⁵

To operationalise this conceptual framework, the comparative matrix in Table 1 organises the analysis around six indicators that correspond to key dimensions of public service innovation. Access and digital enablement capture how far each system reduces barriers to entry and uses digital tools to support vulnerable groups. Outcomes reflect the extent to which innovative practices translate into improved employment, inclusion and quality-of-life results. Financing and governance relate to the institutional and fiscal capacity that enables or constrains innovation, including centralised versus decentralised arrangements. Finally, co-production assesses the degree to which users, communities and intermediary organisations participate in shaping and delivering services. Together, these indicators trace how different welfare regimes embed innovation, digital tools, integration mechanisms and co-productive practices in their support for vulnerable populations (Table 1).

Within this framework, service integration is understood as the coordinated alignment of social, health, employment, and educational interventions around the needs of the person rather than the boundaries of individual institutions. This includes formal collaboration agreements with healthcare providers, schools, employment services, and human rights organisations; shared referral and case-management procedures, and, in some cases, joint budgeting. Community and group work – such as peer support groups, community centres and participatory activities – represents a practical form of co-production, where service users and local actors jointly create supportive environments and informal safety nets. Educational and empowerment-orientated interventions further reinforce co-production by enhancing the capabilities of vulnerable individuals to participate in decision-making and to navigate complex service systems.

At the same time, the empirical evidence supporting these mechanisms varies considerably across countries. In Sweden and the UK, integration and co-production are supported by substantial administrative data and evaluation studies, whereas in Italy documentation is regionally uneven, and in Ukraine evaluation is often limited to pilot initiatives and donor-funded programmes. Furthermore, the effectiveness of digital enablement remains mixed: while Germany and the UK demonstrate relatively mature systems, data from Ukraine and rural Italy indicate persistent gaps in digital literacy, connectivity and uptake. These variations suggest that, although innovation, digital enablement, integration and co-production provide valuable analytical lenses, their practical implementation depends heavily on administrative capacity, funding stability and contextual factors. Seen through these qualified perspectives, the European models analysed in this study represent dynamic but uneven attempts to adapt social services to changing socio-economic conditions, rising levels of poverty, unemployment and social isolation, and evolving expectations of user participation and accountability.

Social workers actively implement programmes that use technology to improve access to services, such as online consultations and digital resources. Innovative practices include mobile outreach teams that visit vulnerable groups, providing urgent assistance and on-site support. Social work programmes may also incorporate rehabilitation, the provision of shelter, and support for education and personal development.^23,24,25 Individuals with mental health disorders may encounter discrimination, social isolation, and inadequate access to treatment. Innovative models of support for this group include outpatient care, peer support groups, and mental health education initiatives. Socially isolated individuals, who for various reasons lack contact with society, also require assistance. Social workers facilitate opportunities for interaction and engagement in community life.

Mobile apps for consultations, online resources, and information exchange platforms improve social service access.²⁶ This is important for young people and disabled individuals who may have trouble getting support. Innovative programmes may use gamification to make learning and socialisation more fun.^8,27 Social support innovations include coaching, mentoring, and support groups. These approaches not only give individuals from vulnerable groups critical knowledge but also offer emotional support, which is a crucial aspect in their overall social well-being. Programmes should emphasise financial literacy, time management, and communication. Innovative European social work models focus on producing more effective, adaptive, and responsive programmes that meet societal demands.

However, implementing innovation in social work presents several challenges. Firstly, financial constraints can hinder the introduction of new technologies and programmes. Many social services operate within tight budgets, limiting their ability to invest in innovative solutions.^28,29,30 This issue is particularly pressing for smaller organisations, which often rely on financial assistance from international organisations, charitable foundations, and government subsidies. The successful adoption of innovation also requires the proper training of professionals. Social workers must possess the skills and knowledge to effectively utilise new technologies and methodologies. This highlights the importance of continuous professional development in the field. Without adequate training, even the most effective innovations may fail to deliver the intended outcomes.^16,28

European countries employ diverse innovative approaches in their work with socially vulnerable populations. These approaches, grounded in psychological techniques, modern strategies, and tailored support methods, aim to address the challenges faced by vulnerable groups. For individuals with disabilities, one of the primary challenges is fostering an inclusive environment and reducing social isolation. In Sweden, personalised rehabilitation plans are widely implemented, incorporating community participation, psychological support, and vocational training. The UK introduced the Access to Work programme, which provides financial assistance for workplace adaptations.¹⁸ In Germany, integrated support centres combine social, medical, and educational services to promote inclusion among individuals with disabilities.¹⁰

For instance, in rural areas, social workers often struggle with limited internet connectivity, which hinders their ability to use digital platforms for service delivery, leaving clients without access to essential services like online consultations or social benefits applications.^31,32,33,34 Additionally, some social workers may be resistant to adopting new technologies due to a lack of training or fear of job displacement, leading to inconsistent implementation of digital tools. On the clients’ side, vulnerable groups, such as individuals with disabilities, may face difficulties in navigating digital platforms due to lack of familiarity with technology or physical limitations, making them less likely to benefit from innovations in service delivery. These examples highlight how both infrastructure issues and social factors can impede access to innovative services.

For the unemployed, the main challenge is loss of motivation and psychological distress due to prolonged joblessness.³⁵ In Germany, the Federal Employment Agency offers retraining programmes and job counselling. The UK employs cognitive behavioural therapy to help restore motivation for work. In Italy, a network of social cooperatives provides temporary employment and support in securing permanent jobs.

The European experience suggests that the effectiveness of social work with vulnerable populations depends on the flexibility of approaches, a focus on individual needs, and the integration of innovative methods. The use of psychological interventions, such as cognitive-behavioural therapy, mentorship schemes, and reminiscence therapy, was shown to enhance the integration and quality of life of these groups.^36,37,38 Ukraine could adopt and adapt these innovations to suit its own socio-economic context.

Social services across different countries operate according to distinct frameworks shaped by legislative acts and regulations.³⁶ The examination of the operations of the Federal Employment Agency (Germany), the Swedish Social Services, the UK’s Department for Work and Pensions (DWP), Italy’s National Social Security Institute (INPS), and Ukraine’s Ministry of Social Policy demonstrated commonalities and differences in their approaches.

In Germany, the labour market and social support operate under two distinct legal frameworks of the Social Code:¹⁰ SGB III (Employment Promotion), administered by the Federal Employment Agency, which covers unemployment insurance benefits, vocational guidance, placement, and training for insured workers and is financed by social insurance contributions; and SGB II (Basic Income Support for Jobseekers), implemented by Jobcenters jointly run by the Federal Employment Agency (BA) and municipalities, which provides means-tested income support and activation/reintegration services for work-capable persons, financed from general taxation with municipal co-funding. Service delivery is decentralised within this national framework and increasingly digitally enabled (eServices, BA-Mobil, Jobbörse).

The United Kingdom’s social welfare system operates under a dual structure. The DWP administers national benefits and employment support – including Universal Credit, disability benefits, and employment programmes such as Access to Work, which provides financial and practical assistance to help people with disabilities enter and remain in employment. These services focus primarily on income maintenance, employability, and workplace adjustments. In contrast, local authorities (county and unitary councils) are responsible for adult and children’s social care. Their duties are governed by the Care Act 2014³⁹ (for adults) and the Children Act 1989⁴⁰ and 2004⁴¹ (for children and families). Local authority social workers assess individual needs and develop care plans in partnership with clients and carers. Local authorities also collaborate with the National Health Service (NHS), voluntary organisations, and community groups to deliver integrated services addressing health, housing, and social inclusion. This decentralised approach allows local services to adapt to community contexts and ensure continuity of support for vulnerable adults, children, and families.^12,18,42

Germany, Sweden, the UK, and Italy have extensive experience in implementing social innovations, contributing to the development of new approaches in the provision of social services. These countries actively adopt modern social assistance models, demonstrating high effectiveness in addressing various social issues. Their innovative strategies not only enhance existing support mechanisms for vulnerable populations but also enable the adaptation of new approaches to different national contexts, considering variations in socio-economic conditions. The diverse range of social programmes implemented in these countries provides an opportunity for comparative analysis, allowing the identification of best practices that can be adapted to the specific cultural and economic contexts of other nations.

Germany actively integrates digital technologies to monitor the employment status of job seekers through online platforms, establishing efficient systems for retraining and professional rehabilitation based on digital courses. Sweden focuses on innovations in the form of electronic platforms that provide rapid access to social services. Moreover, the country implements self-employment support programmes for individuals with disabilities, enabling them to achieve economic independence.^{37,38,39,40,41,42,43,44,45,46,47,48} Meanwhile, Italy is actively developing online services for pension and social benefit applications and promoting social entrepreneurship, thereby creating employment opportunities and fostering economic engagement among vulnerable groups. These innovative approaches enhance the accessibility, efficiency, and inclusivity of social services, addressing the needs of socially vulnerable groups in each of these countries.

For the comparative analysis of social innovations in Germany, Sweden, the UK, and Italy, several key aspects were considered, including the financing of social programmes, the structure of social welfare systems, the social integration of vulnerable groups, the accessibility of social services, and the role of social responsibility and state oversight. Each of these aspects is of vital importance when evaluating the effectiveness and feasibility of social innovations implemented in these countries.

The financing of social programmes influences the accessibility and sustainability of these services. In Germany and the UK, social programmes are funded through tax revenues and government budget expenditures, ensuring relatively high levels of service accessibility for the population while imposing certain financial constraints on new initiatives. In Sweden, both central and local government bodies contribute to the financing of social programmes, allowing for the effective adaptation of services to meet the needs of local communities. In Italy, while social programmes are primarily funded through the state budget, the regional administration of social services introduces specific features that enable flexibility in funding and programme implementation at the local level.

The structure of social welfare systems in these countries also differs. Germany and the UK operate more centralised systems, which allow for the standardisation of social service provision at the national level but may limit their ability to rapidly adapt to changing circumstances. By contrast, Sweden has a decentralised system in which local authorities enjoy autonomy in service provision, allowing them to respond swiftly to the evolving needs of their population. Italy combines elements of both centralised and decentralised systems, maintaining national-level efficiency while granting considerable flexibility to regional administrations.

The social integration of vulnerable groups is a crucial aspect in assessing the inclusivity of a society.^{34,35,36,37,38,39,40} In Germany and the UK, various programmes are in place to support the integration of individuals with disabilities, including specialised services and employment assistance. In Sweden, social integration is fostered through a comprehensive approach that encompasses not only material support but also psychological assistance to facilitate the inclusion of vulnerable groups within society. In Italy, integration programmes are often regionally specific, allowing strategies to be tailored to the needs of particular population groups. However, the country continues to work towards improving inclusivity at the national level.

The accessibility of social services is determined by access to essential provisions such as healthcare, education, and housing.⁴⁸ In Germany and the UK, the level of service accessibility is generally high, particularly in urban areas. Nevertheless, challenges persist in remote regions, particularly for individuals with disabilities. Sweden, due to its decentralised system, ensures a more equitable distribution of services across the country, thereby promoting social fairness.¹⁵ Italy also has a well-developed social services system, yet regional disparities may lead to unequal access to services across different parts of the country. Social responsibility and state oversight in these countries are shaped by the role of the government in managing social programmes and the degree of societal involvement.⁴⁹ In Germany and the UK, state control over social services is relatively high, ensuring system stability. Sweden places emphasis on civic participation and partnerships with the private sector, making the system more flexible and adaptive. Italy actively involves not only state institutions but also local communities, enabling social programmes to be integrated into regional contexts.¹⁶

Germany, Sweden, the UK, and Italy’s social welfare agency regulations influence vulnerable group service innovations. German Social Workers are employed by the Federal Employment Agency, which schedules and frequencies visits dependent on client needs.¹⁰ The focus is on the unemployed, disabled, and poor. Social workers must meet with unemployed people monthly to evaluate their job search and adjust their strategies. Following its social democratic model, Sweden assists and integrates underprivileged groups weekly or monthly, depending on complexity. Mental health support is mandated under UK DWP law. Social workers must contact clients every two weeks to ensure reintegration. Psychotherapy and detox are given to drug addicts. Italy prioritises social business and social welfare integration. Disability employment training is available via INPS. Under proper guidelines, social workers assess clients’ professional adaptation monthly. Ukraine’s Ministry of Social Policy oversees social services for low-income, large, disabled, and internally displaced families. Unlike Western countries, Ukraine does not restrict the frequency of client visits, potentially influencing the effectiveness of help. Regional help regularly reaches internally displaced people.⁵⁰

To enhance social work for vulnerable populations in Ukraine, concrete steps include developing individualised support plans for people with disabilities, integrating professional training and rehabilitation, and fostering inclusive work environments through workplace adaptations.^51,52,53 For migrants, integration programmes focusing on language, cultural adaptation, and legal support, along with mentoring initiatives and integration centres, are essential. For the unemployed, expanding retraining programmes aligned with market needs and introducing psychological support to rebuild motivation are key. These efforts require cross-sectoral cooperation between government, civil society, businesses, and volunteers, along with funding mechanisms from public-private partnerships and international aid. Success indicators include increased employment rates, improved psychological well-being, better service accessibility, and the creation of inclusive, sustainable practices across regions.⁵⁴

Countries with centralised governance, like Germany and Ukraine, tend to have standardised approaches to service delivery, which ensures uniformity but may struggle with adapting services to local needs. In contrast, decentralised systems, such as those in Sweden and the UK, offer greater flexibility and responsiveness to regional demands, fostering more personalised and adaptive support for vulnerable groups. This decentralisation often leads to better integration of local contexts and faster implementation of new policies.

Regarding service delivery models, Sweden and the UK emphasise personalised care, particularly for individuals with disabilities, the elderly, and refugees, ensuring that services are tailored to meet specific needs. Meanwhile, Germany and Italy rely on standardised approaches, though they incorporate elements of personalisation for vulnerable groups. The effectiveness of these systems is often linked to the ability to adapt to changing needs, with more decentralised and innovative systems generally showing better outcomes in employment reintegration and social inclusion.¹⁶ The framework demonstrates that responsive and flexible service models, combined with innovative technologies, significantly enhance the effectiveness of social services for vulnerable populations. Decentralised governance, along with targeted innovation adoption, can create more inclusive and efficient social support systems.

To enhance the effectiveness of social services in Ukraine, practical recommendations must be grounded in realistic cost assumptions, transparent institutional responsibilities, and measurable indicators. These recommendations should align with the State Social Policy Strategy 2030, the National Digital Transformation Plan, and previously published expenditure benchmarks from the Ministry of Social Policy, the Ministry of Digital Transformation, and international partners such as UNICEF, GIZ, and the World Bank.^{22,23,24,25,26} Ukraine continues to face systemic constraints – including limited fiscal capacity, staff shortages, regional disparities, and digital exclusion – that require a phased and evidence-based approach to reform.

A central priority is the development of personalised support plans for persons with disabilities. Cost estimates of €400–600 per beneficiary annually are consistent with average expenditures recorded in EU disability-inclusion pilot programmes and Ukrainian municipal social service budgets in 2021–2023. Introducing a pilot in Kyiv and Lviv would require approximately €0.6–0.9 million over the first six to twelve months, with nationwide scaling projected at €6–10 million annually depending on beneficiary coverage. Sensitivity analysis suggests a ±15% variation under conditions of inflation or increased staffing needs. Indicators for monitoring include the share of clients with approved individual plans, employment reintegration rates, quality-of-life scores (EQ-5D or WHOQOL), and user satisfaction surveys.^{18,19,20,21,22,23,24} Data may be sourced from the State Social Service Information System, the State Employment Service, and municipal registries.

The creation of a unified digital platform for social services should follow the interoperability standards of the Diia ecosystem and comply with the Law of Ukraine “On Personal Data Protection”, harmonised with GDPR norms.²² Digital platform development costs of €2-4 million are consistent with expenditures for similar GovTech projects in Poland, Estonia, and Croatia. A prototype could be finalised within twelve months, followed by regional pilots by month eighteen and full rollout by the second year. Annual maintenance (15-20% of development costs) reflects IT-sector benchmarks. Key indicators include the number of active users, transaction completion time, service accessibility for persons with disabilities (WCAG compliance), and the proportion of rural and low-income users accessing digital services.^{10,11,12,13,14} Given evidence from the World Bank and the Ministry of Digital Transformation indicating that up to 25–30% of rural households lack stable broadband access, hybrid service models must remain available.

Expanding vocational retraining and psychological support for unemployed individuals is another strategic direction. The estimated €1–1.5 million per retraining hub corresponds to average costs for educational centres in EU-funded employment programmes (e.g., EaSI, NEET reintegration). Establishing ten hubs in major urban centres would enable annual coverage of 20,000–25,000 participants. Sensitivity ranges depend on personnel salaries and sectoral demand, varying by ±20%. Monitoring indicators include training completion rates, post-training employment within 6-12 months, certifications obtained, and psychological well-being improvements measured by validated scales (e.g., GAD-7, PHQ-9).²²

Addressing the digital divide is essential for equitable access. Evidence from the Ukrainian Association of Cities and UNICEF demonstrates significant disparities in digital literacy among older adults, individuals with disabilities, and rural communities. Local authorities, NGOs, and community centres should coordinate digital literacy programmes, employing workshops, mobile learning units, and peer mentoring. Estimated annual costs of €0.5-1 million align with similar community digital inclusion programmes in Central and Eastern Europe. Effectiveness indicators include participation numbers, pre-/post-training digital literacy improvements (using the European Digital Competence Framework), and the frequency of digital social service use.^{41,42,43,44,45,46,47}

Strengthening social workers’ professional competence requires institutionalised continuous training coordinated by the National Academy of Public Administration and the Ministry of Social Policy. Annual costs of €0.8-1 million for 5,000 trainees reflect current Ukrainian public-sector training budgets and international benchmarks. Monitoring indicators include certification completion rates, staff retention, satisfaction indices, and user-reported service quality.^{15,16,17,18,19,20,21,22}

The overall financing model should combine national budget allocations with international funding streams such as NDICI-Global Europe, the World Bank Social Inclusion Programme, USAID, GIZ, and SIDA. The Ministry of Finance should coordinate budget planning and resource mobilisation, while the Ministry of Social Policy oversees implementation.^{28,29,30,31,32,33,34,35,36} A phased timeline is recommended: six months for preparatory assessments, up to eighteen months for pilot implementation with midline reviews, and three years for nationwide rollout. Monitoring and evaluation should rely on baseline-midline-endline comparisons, using indicators such as vulnerable population coverage, employment reintegration rates, service delivery times, and cost-effectiveness ratios.²²

Given conflict-related disruptions, risk management must prioritise service continuity, secure data governance, and flexible delivery mechanisms. Empirical evidence from the Ministry for Reintegration and humanitarian organisations indicates that conflict-affected regions face unstable infrastructure, uneven staff availability, and heightened vulnerability. Hybrid delivery models – combining in-person, digital, and mobile services – are necessary to maintain inclusivity. Data governance must comply with the Law on Personal Data Protection and adopt GDPR-equivalent protocols, ensuring encryption, secure storage, and explicit user consent.¹⁴ Continuous coordination with the Ministry for Reintegration of Temporarily Occupied Territories is crucial to safeguard access to services and mitigate regional inequalities.

By linking these recommendations to realistic financial benchmarks, clearly defined institutional responsibilities, measurable indicators, and a strong evidence base, Ukraine can move toward a more resilient, adaptive, and innovation-oriented social welfare system. Embedding reforms within national strategic frameworks and aligning them with EU social policy standards will support transparency, accountability, and sustainability, ultimately ensuring that vulnerable populations receive equitable and effective support.
