Health care of people in homelessness: a comparative study of mobile units in Portugal, United States and Brazil

Igor da Costa Borysow Eleonor Minho Conill Juarez Pereira Furtado About the authors

Abstract

This paper describes and analyzes the legal and normative framework guiding the use of mobile units in Portugal, United States and Brazil, which seek to improve access and continuity of care for people in homelessness. We used a comparative analysis through literature and documentary review relating three categories: context (demographic, socio-economic and epidemiological), services system (access, coverage, organization, management and financing) and, specifically, mobile units (design, care and financing model). The analysis was based on the theory of convergence/divergence between health systems from the perspective of equity in health. Improving access, addressing psychoactive substances abuse, outreach and multidisciplinary work proved to be common to all three countries, with the potential to reduce inequities. Relationships with primary healthcare, use of vehicles and the type of financing are considered differently in the three countries, influencing the greater or lesser extent of equity in the analyzed proposals.

Introduction

Ensuring access also to vulnerable groups has become an objective of some contemporary health systems, as evidenced by the development of new care models11. Massignam FM, Bastos JLD, Nedel FB. Discriminação e saúde: um problema de acesso. Epidemiol e Serviços Saúde 2015; 24(3):544-541.. This paper describes and analyzes proposals aimed at people in homelessness in Portugal, the United States (USA) and Brazil, respectively called Street Teams, Mobile Outreach Clinics and Clinics on the Street.

Under the category “people in homelessness” (PIH) are individuals who share the condition of extreme poverty, the use of streets and public spaces (or possibly hostels) as a primary place of survival, overnight stay and personal relationships, on a temporary or permanent basis. On the other hand, they evidence heterogeneous reasons for going to the streets and life strategies22. Mattos RM. Situação de rua e modernidade: a saída das ruas como processo de criação de novas formas de vida na atualidade. São Paulo: Universidade São Marcos; 2006.,33. Brasil. Ministério da Saúde (MS). Manual sobre o cuidado à saúde junto a população em situação de rua. Brasília: MS; 2012.. PIH make up excess population groups that do not keep pace with socio-economic transformations and/or are victims of circumstances – environmental disasters, expropriation, forced migration, etc. The mismatch in relation to the current social model leads to negative discrimination and repressive actions44. Bauman Z. Vidas desperdiçadas. Rio de Janeiro: Jorge Zahar; 2005., since they are considered by society as “an inconvenient and threatening presence”55. Varanda W, Adorno RCF. Descartáveis urbanos: discutindo a complexidade da população de rua e o desafio para políticas de saúde. Saude Soc 2004; 13(1):56-69.. The prevalence of mental disorders and alcohol abuse and other drugs use adds to PIH breaking with their social networks and protective groups, increasing their vulnerability66. Silva MLL.

PIH are by the thousands in Brazil, the United States and Portugal77. Estados Unidos da América. The 2013 Annual Homeless Assessment Report (AHAR) to Congress [Internet]. Washington D.C.; 2013. [cited 2016 Jan 10]. Available from: https://www.hudexchange.info/resources/documents/ahar-2013-part1.pdf

This research seeks to contrast what is common and diverse between the standards geared to PIH itinerant health care, relating national socioeconomic and institutional contexts. It also aims to highlight the contributions and limitations of health equity initiatives for its target population, that is, to analyze the investment and organization of systems and services in the differential and fair treatment of a population that experiences inequalities2121. Vieira-da-silva LM. Eqüidade em saúde: uma análise crítica de conceitos. Cad Saúde Publica 2009; 25(Supl. 2):217-226., such as PIH. Given the lack of comparative studies on this subject, we will place the Brazilian proposal under a comparative international perspective, so that the experience of other countries represents an analytical mirror2222.

Methodology

Comparison is the analytical resource2424. Yin R. Estudo de caso: planejamento e métodos. 3a ed. Porto Alegre: Bookman; 2005. of this multiple case study2525. Conill EM. Sistemas Comparados de Saúde. In: Tratado de Saúde Coletiva. Rio de Janeiro: Hucitec, Fiocruz; 2006. p. 563-614.. We outline the focus on the PIH itinerant initiatives in Portugal, the United States of America and Brazil. We chose the U.S. based on the pioneering provision of this type of service and the volume of indexed publications on the subject; Portugal was chosen for its cultural proximity and similarities between the principles and organizational design of the Portuguese National Health System (SNS) and the Brazilian Unified Health System (SUS).

We define as units of analysis proposals by the federal governments regarding mobile services, considering the national socio-political situation and national health systems2626. Conill EM. A análise comparada na avaliação de serviços e sistemas de saúde. In: Desafios da avaliação de programas e serviços em saúde. Campinas: Unicamp; 2011.. We define three descriptive categories: context, characteristics of the service system and facilities. The first uses a set of indicators that act as approaches (proxy variable) to locate the main factors that influence the health situation – demographic, socioeconomic and epidemiological indicators. We include in this item indicators of health problems with a higher prevalence among PIH, such as alcohol abuse and other drugs use33. Brasil. Ministério da Saúde (MS).

The context description summarizes the history of health systems, placing the political-institutional option against the social protection in health prevalent in each country. The operationalization of the systems’ characteristics prioritized access, coverage, organization and management of services and the financing method, as expressed in the normative and legal framework2525.

This paper is based on bibliographical and documentary review, considering laws, governmental ordinances and health sector booklets, among others. Scientific papers were identified through SciELO, PubMed and Google Scholar databases, with the following combinations of terms: in English, “mobile outreach services” and “homeless”, “mobile health” and “homeless”, “mobile unit health service” and “homeless”, and in Portuguese “saúde” (health) and “morador de rua” (homeless). The analysis systematizes similarities and differences between the proposals of mobile units, based on the theory of convergence / divergence between contemporary systems2525. Conill EM.

. In that same year, there were approximately 5,000 PIH, 0.04% of the total population88. Pereira AC, Oliveira M. Mais de cinco mil pessoas sem abrigo em Portugal. Público [Internet]. 2014 Mar 31.

. When Portugal joined the European Union in 1986, there was a period of improvement in socioeconomic indicators, but they started to recede by mid-2009 with the worsening of the financial crisis in this geopolitical space, together with austerity social policies4343.

The SNS was created in 1979, based on ensured universal access, tax-derived financing and partial decentralization of responsibilities in the provision of care to Regional Health Administrations (ARS); but the SNS started with low funding, little development of own services and access problems. Since 1990, the private sector increased its participation in the SNS in an international context of strengthening the neoliberal model4444. Santos CBG. Disparidades na Distribuição Geográfica de Recursos de Saúde em Portugal. Braga: Universidade do Minho; 2012..

There was a gradual favoring of the primary healthcare model, but in spite of its good performance4444. Santos CBG. Disparidades na Distribuição Geográfica de Recursos de Saúde em Portugal. Braga: Universidade do Minho; 2012.,4545. Observatório Português dos Sistemas de Saúde. Relatório Primavera 2014 - Saúde: síndroma de negação [Internet]. Lisboa; 2014 Nov. [cited 2016 Mar 25].

, its implementation was reduced with the recent economic crisis. By 2013, spending remained predominantly public (66% of the total), with an increase in private expenditure (out-of-pocket and insurance)4646. Organisation for Economic Co-operation and Development (OECD). Health Resources [Internet]. 2013. [cited 2016 Mar 25].

. Thus, there are now three health subsystems in Portugal: SNS, insurance of some professional categories and private insurance.

Some Portuguese health indicators are close to the average of the other countries of the Organization for Economic Cooperation and Development (OECD), while others – such as cerebrovascular disease mortality, mental health care and, mainly, HIV/AIDS prevalence – show an unfavorable situation in all European countries4545.

. In addition, in 2012, 2.7% of the population reported having used some type of drug in the last 12 months, excluding alcohol and tobacco4848. Portugal. Ministério da Saúde (MS). Serviço de Intervenção nos Comportamentos Aditivos e nas Dependências. Sinopse Estatística. Lisboa: MS; 2014., and in 2013, a high rate of alcohol consumption per person per year was observed4949.

, and neuropsychiatric disorders contributed to 25.6% of the global burden of disease.

HIV/AIDS and psychoactive substance use indices have been the argument for the implementation of mobile health teams since 2001, such as Street Teams (ER), aimed at drug users4545.

However, increased PIH in the country led to the establishment, in 2006, of an interinstitutional group that elaborated the “National Strategy for the Integration of Homeless People” (ENIPSA)1111. Portugal. Estratégia Nacional para integração de pessoas sem-abrigo. Lisboa; 2009.. ENIPSA considered the ER as the main means of addressing, monitoring and referring PIH to other points in the network to receive basic care.

Proposals for Portuguese ERs were reorganized in 2013 through the establishment of the General-Directorate for Intervention on Addictive Behaviors and Dependencies (SICAD), responsible for health programs related to this theme5353.

The US and the Mobile Outreach Clinics

A country with a large territorial area and a population estimated at more than 320 million inhabitants5555. United States Census Bureau. Population [Internet]. 2015 [cited 2016 Jan 10]. Available from: http://www.census.gov/topics/population.html

, which meant 0.20% of the population. A significant increase in this figure was observed in the 1970s with the de-hospitalization of psychiatric patients, and a new increase occurred following social programs cuts in the 1980s5656. Donohoe M. Homelessness in the United States: History, Epidemiology,Health Issues, Women, and Public Policy. Medscape Ob/Gyn Women’s Heal 2004; 9(2).. What happened in 2013 was that a large majority of men over 25 years of age, and 42.17% of people had severe mental disorders and/or disorders related to the use of psychoactive substances77.

The country has a high GDP per capita, an HDI of 0.915 and a Gini of 41.1. By 2013, per capita health expenditure was twice the average of OECD countries and predominantly private (around 52%).

Throughout the twentieth century, the U.S. health system was structured by a business and philanthropic model with a predominance of financing and private service provision. While U.S. states have autonomy in coordinating the sector5858. Costa JP. A reforma Obama e o sistema de saúde dos EUA. Arq Med 2013; 27(4):158-167., the U.S. Department of Health and Human Services (HHS) manages the entire network of care, regulating private plans and services. In 1965, two subsystems, Medicaid, and Medicare were established. The first is care-oriented, aimed at low-income people, with federal subsidies; the second is social insurance financed by fiscal sources and wage contributions to cover people over 65 or who have specific morbidities. HHS also runs programs for other specific groups, such as war veterans and low- and middle-income children5858. Costa JP. A reforma Obama e o sistema de saúde dos EUA. Arq Med 2013; 27(4):158-167..

In 2010, 49% of Americans were covered by employer-sponsored insurance, 17% had Medicaid, 12% had Medicare and 16% of individuals had no social protection in health5959.

Access difficulties and rising expenditures contributed to the approval of the Patient Protection and Affordable Care Act (ACA), starting the reform known as Obamacare6060. United States of America. Patient Protection and Affordable Care Act. Washington D.C.; 2010.. ACA is based on expanded coverage due to mandatory private insurance, increased regulation, Medicare and Medicaid expanded coverage, reforms in the care model, among other actions2525. Conill EM. Sistemas Comparados de Saúde. In: Tratado de Saúde Coletiva. Rio de Janeiro: Hucitec, Fiocruz; 2006. p. 563-614.. Despite criticisms to the business model with private insurance intermediation, this reform has increased access of PIH to services2525. Conill EM. Sistemas Comparados de Saúde.

The use of PIH-oriented mobile outreach clinics began in the 1970s.6464. Moulavi D, Bushy A, Peterson J, Stullenbarger E, Muolavie D. Thinking about a mobile health unit to deliver services? Things to consider before buying. Aust J Rural Health 2000; 8(1):6-16. Given the serious situation of PIH in the United States, several social movements pressured the federal government to ensure rights to this public, which led to the establishment of a specific section for PIH in the Anti-Drug Abuse Act6565. United States of America. Public Law 99th Congress 99-570. Washington D.C.; 1986.. In 1987, under intense pressure from institutions and movements linked to the issue, and from the mobilization of Congressmen Stewart McKinney and Bruce Vento, Congress enacted the McKinney Homeless Assistance Act (later renamed the McKinney-Vento Homeless Assistance Act), which created amendments to the Public Health Service Act for the implementation of PIH services, including outreach strategies6666. United States of America. Public Law 100-77. To provide urgently needed assistance to protect and improve the lives and safety of the homeless, with special emphasis on elderly persons, handicapped persons, and families with children.

Available from: http://www.nationalhomeless.org/publications/facts/McKinney.pdf

. The McKinney-Vento Act does not address the organization of mobile teams; it only mentions that they are primary healthcare services that can be complemented by specific teams geared to the treatment of drug addiction and mental disorders.

A study carried out between 2006 and 20071010. Post P. Mobile Health Care for Homeless People : Using Vehicles to Extend Care. Nashville: National Health Care for the Homeless Council; 2007. showed that most of the investigated teams used their own vehicle and financing derived from federal, municipal and corporate funds. They consisted of several professional categories, including a doctor in just over half of them1010. Post P. Mobile Health Care for Homeless People : Using Vehicles to Extend Care. Nashville: National Health Care for the Homeless Council; 2007.. Currently, several elements point out a synergy of policies to overcome PIH’s difficult access to health services. ACA’s implementation expanded the criteria for inclusion in Medicaid and facilitated the funding of innovative experiences. These actions have led to a decreased number of PIH as from 2010, despite national recession6161. United States of America. United States Interagency Council on Homelessness. Opening Doors: Federal strategic plan to prevent and end homelessness. Washington D.C.: United States Interagency Council on Homelessness; 2015..

With the enactment of the Constitution in 1988, in Brazil, health became a citizenship right ensured by the SUS7171. Bahia L. Padrões e mudanças no financiamento e regulação do sistema de saúde brasileiro: impactos sobre as relações entre o público e privado. Saúde Soc 2005; 14(2):9-30., whose objective is to provide universal, comprehensive and equitable coverage through organized networks of services under shared management between federal, state and municipal governments7272. Brasil. Constituição da República Federativa do Brasil de 1988. Diário Oficial da União 1988; 5 out.. However, low public funding resulting from the 1990s neoliberal agenda fostered a significant expansion of private health plans. From the standpoint of financing and service delivery, the Brazilian health system can be considered a hybrid system consisting of three subsystems: the SUS financed with state resources and universal access with emphasis on primary health care; a private subsystem, whether for profit or not, maintained with public and private funds; and the supplementary subsystem composed of several types of private plans, which also receives tax subsidies7171.

PIH health strategies emerged from municipal experiences between 1980 and 2000, some related to primary healthcare and others aimed at homeless users of psychoactive substances7777. Nery-Filho A, Valério ALR, Monteiro LF. Guia do projeto Consultório de Rua. Brasília, Salvador: SENAD, CETAD; 2012.

Since 2007, the Ministry of Social Development has teamed up with other ministries (Ministry of Cities, Education, Health, Justice, Labor and Employment, the Special Secretariat for Human Rights and the Federal Government Public Defender), with workers in this area and movements, which resulted in the production of the National Policy for the Social Inclusion of People in Homelessness8080.

Based on this document, the Ministry of Health (MS) developed an emergency plan to strengthen and expand the so-called Clinic of Street, mobile itinerant services based on harm reduction strategies and drug addiction treatment8181.

The CnR is a PIH-exclusive PHC multiprofessional service. It includes care for alcohol abuse and use of other drugs through outreach and sharing of actions with other points in the network and other sectors. Its implementation is mandatory according to the number of HIP identified in municipalities. Three types of teams were defined and only modality III provides for the inclusion of doctors8585. Brasil.

Discussion

Convergences for reducing inequity: objectives, outreach, multiprofessionality and harm reduction

Despite the structural differences in the health policies of the countries surveyed, all three recognize as main problem the barriers in the access of PIH to the services, implanting strategies and similar resources of approach and care5252. Portugal. Decreto Lei no 183/2001, de 21 de Junho. Diário da República 2001.,6666. United States of America. Public Law 100-77. To provide urgently needed assistance to protect and improve the lives and safety of the homeless, with special emphasis on elderly persons, handicapped persons, and families with children. Washington D.C.; 1987 p. 482-538.,8383. Brasil. Portaria nº 122, de 25 de janeiro de 2012. Define as diretrizes de organização e funcionamento das Equipes de Consultório na Rua. Diário Oficial da União; 2012.(Table 3). Outreach, followed by referral to the other points of the network proves to be an essential strategy in the linkage and continued care to people in homelessness, with potential to facilitate the access of services by the population1313. Lemke RA, Silva RAN. A busca ativa como princípio político das práticas de. Estud e Pesqui em Psicol 2010; 10(1):281-295.,2020. Ferreira CPS, Rozendo CA, Melo GB. Consultório na Rua em uma capital do Nordeste brasileiro: o olhar de pessoas em situação de vulnerabilidade social. Cad Saude Publica 2016; 32(8):1-10.. The approach and provision of care before issues related to alcohol abuse and use of other drugs was also a convergent action5252. Portugal. Decreto Lei no 183/2001, de 21 de Junho. Diário da República 2001.,6666. United States of America. Public Law 100-77. To provide urgently needed assistance to protect and improve the lives and safety of the homeless, with special emphasis on elderly persons, handicapped persons, and families with children. Washington D.C.; 1987 p. 482-538.,8383. Brasil. Portaria nº 122, de 25 de janeiro de 2012. Define as diretrizes de organização e funcionamento das Equipes de Consultório na Rua. Diário Oficial da União; 2012., which is consistent with the high prevalence of psychoactive substances among PIH (as highlighted by PIH censuses of the US and Brazil) and among the general population of the three countries studied (Table 1).

We identified as a convergent resource the establishment of the teams through the integration of professionals of different graduations. The actual multidisciplinary character seems to face the complexity of its object, enabling articulation of different perspectives on the issues8787. Almeida Filho N. Transdisciplinaridade e Saúde Coletiva. Cien Saude Colet 1997; 11(1972):1-18.,8888. Furtado JP. Equipes de referência: arranjo institucional para potencializar a colaboração entre disciplinas e profissões. Interface (Botucatu) 2007; 11(22):239-255..

Therefore, outreach and harm reduction strategies associated with multiprofessional teams’ resources would favor the promotion of equity by adapting mobility and broadening coverage, range of actions and team composition to people’s essential needs, and alleviating barriers imposed by social inequality, often reproduced by the health network itself2121. Vieira-da-silva LM. Eqüidade em saúde: uma análise crítica de conceitos. Cad Saúde Publica 2009; 25(Supl. 2):217-226..

Divergent actions among the proposals: care models and intersectorality

In the United States and Brazil, mobile services originated in the care of alcohol and other drug users5252. Portugal. Decreto Lei no 183/2001, de 21 de Junho. Diário da República 2001.,6565. United States of America. Public Law 99th Congress 99-570. Washington D.C.; 1986.,7777. Nery-Filho A, Valério ALR, Monteiro LF. Guia do projeto Consultório de Rua. Brasília, Salvador: SENAD, CETAD; 2012., but were later directed and integrated with primary healthcare6666. United States of America. Public Law 100-77. To provide urgently needed assistance to protect and improve the lives and safety of the homeless, with special emphasis on elderly persons, handicapped persons, and families with children. Washington D.C.; 1987 p. 482-538.,8383. Brasil. Portaria nº 122, de 25 de janeiro de 2012. Define as diretrizes de organização e funcionamento das Equipes de Consultório na Rua. Diário Oficial da União; 2012.. Thus, Portuguese ERs focused on the strategy of care to users of psychoactive substances in response to the high levels of HIV/AIDS and substance abuse in the country8989. Hortale VA, Pedroza M, Rosa MLG. Operacionalizando as categorias acesso e descentralização na análise de sistemas de saúde. Cad Saude Publica 2000; 16(1):231-239., a restriction reinforced by the last decree-law5454. Portugal. Portaria no 27 de 2013. Diário da República 2013., even with the proposed expanded functions of ERs by ENIPSA1111. Portugal. Estratégia Nacional para integração de pessoas sem-abrigo. Lisboa; 2009.. Working through primary healthcare, Brazilian and U.S. services enhance comprehensive health care for PIH, considering their complexity and the identified barriers to access. They provide assistance to the most common problems of the population, such as tuberculosis, avoiding excessive referrals to specialties9090. Donaldson M, Yordy K, Lohr K, Vanselow N. Primary Care: America’s Health in a New Era. Washington: National Academies Press; 1996.. A broader approach enables a better linkage and continuity to treatments, and care for comorbidities1919.

Nuttbrock L, Rosenblum A, Magura S, McQuistion H. Broadening perspectives on mobile medical outreach to homeless people. J Health Care Poor Underserved 2003; 14(1):5-16.. In all three countries, but especially Brazil, primary healthcare could contribute to reducing morbidities among men, which are predominant among PIH, who have the highest rates of potential years of life lost (see Table 1) and are less seeking health services in the country9292. Figueiredo W. Assistência à saúde dos homens: um desafio para os serviços de atenção primária. Cien Saude Colet 2005; 10(1):105-109..

Otherwise, services proposed by the last Portuguese legislation do not serve PIH in general, and they need to seek comprehensive care elsewhere in the network7777. Nery-Filho A, Valério ALR, Monteiro LF. Guia do projeto Consultório de Rua. Brasília, Salvador: SENAD, CETAD; 2012.,9494. Márcia F, Linhares P. Práticas de saúde das equipes dos Consultórios de Rua Health practices by teams from Street Outreach Offices Prácticas de salud de los equipos de atención callejera. 2014; 30(4):805-814.. Restricting the care modality focused here may result in limited and stigmatizing actions vis-à-vis the target population, with the risk of providing assistance only to urgent issues, not promoting processes to improve the overall quality of health9595. Bento A, Barreto E. Sem-amor, Sem-abrigo. Lisboa: Clieipsi Editores; 2002. and not favoring the overcoming of inequity2121. Vieira-da-silva LM. Eqüidade em saúde: uma análise crítica de conceitos. Cad Saúde Publica 2009; 25(Supl. 2):217-226.. Moreover, the lack of a more organized axis of health actions can lead to segmented and/or overlapping strategies by ERs9696. Gomes TS, Guadalupe S. Redes de Suporte Formal ao Sem-Abrigo na Cidade de Coimbra 1. Interações 2011; 21:71-94..

Intersectoral action received greater investment from the U.S. federal government, which articulated intersectoral and interinstitutional partnerships to care for PIH, setting an organized network that promoted a reduced number of this population group, considering its multiple needs77. Estados Unidos da América. The 2013 Annual Homeless Assessment Report (AHAR) to Congress [Internet]. Washington D.C.; 2013. [cited 2016 Jan 10].

,6161. United States of America. United States Interagency Council on Homelessness. Opening Doors: Federal strategic plan to prevent and end homelessness. Washington D.C.: United States Interagency Council on Homelessness; 2015.. Both the Brazilian and Portuguese governments proposed the coordination of several sectors in their national strategies1111. Portugal. Estratégia Nacional para integração de pessoas sem-abrigo. Lisboa; 2009.,8080. Brasil. Ministério de Desenvolvimento Social e Combate à Fome (MDSCF). Política Nacional para Inclusão Social da População em Situação de Rua. Brasília: MDSCF; 2008.. However, only Brazilian ordinances in the health sector covered this principle8282. Brasil. Portaria nº 3.088, de 23 de dezembro de 2011. Institui a Rede de Atenção Psicossocial para pessoas com sofrimento ou transtorno mental e com necessidades decorrentes do uso de crack, álcool e outras drogas, no âmbito do Sistema Único de Saúde (SUS).

Diário Oficial da União; 2012., and both countries have not displayed concrete results on this action so far. Intersectorality for PIH care is an essential strategy in face of the complexity of its demands, avoiding inadequate services to its users and promoting equity9797. Borysow IC. Acesso e equidade: avaliação de estratégias intersetoriais para a população em situação de rua com transtorno mental grave [tese]. São Paulo: Universidade Federal de São Paulo; 2013..

Diverse resources and limitations to the fight against inequity

The existence or not of a vehicle available to the teams seems to be an indicator of the actual capacity to monitor people in their respective territories, since this resource enables transport of professionals along with their equipment and supplies, besides the transfer of patients to other services1919. Hallais JAS, Barros NF. Consultório na Rua: visibilidades, invisibilidades e hipervisibilidade. Cad Saude Publica 2015; 31(7):1497-504.,6464. Moulavi D, Bushy A, Peterson J, Stullenbarger E, Muolavie D. Thinking about a mobile health unit to deliver services? Things to consider before buying. Aust J Rural Health 2000; 8(1):6-16.. By omitting the requirement of a car in ERs’ proposals, the Portuguese initiative compromises one of the pillars of this strategy, particularly based on the mobility of its team, not contributing to reduced inequity before the difficult access of PIH to services.

With regard to financing, Portugal and the U.S. operate with a public-private resource sharing scheme. However, such legislation differs from one another because of the fact that Portuguese ERs are outsourced, while U.S. law allows both the public and third parties to perform the service, even under a system heavily influenced by private initiative5252. Portugal. Decreto Lei no 183/2001, de 21 de Junho. Diário da República 2001.,5454. Portugal. Portaria no 27 de 2013. Diário da República 2013.,6666. United States of America. Public Law 100-77. To provide urgently needed assistance to protect and improve the lives and safety of the homeless, with special emphasis on elderly persons, handicapped persons, and families with children. Washington D.C.; 1987 p. 482-538.. In the case of the Brazilian proposal, the federal government and municipalities bear the costs and perform the CnRs8383. Brasil. Portaria nº 122, de 25 de janeiro de 2012. Define as diretrizes de organização e funcionamento das Equipes de Consultório na Rua. Diário Oficial da União; 2012..

Direct contracting by a public body ensures stability and favors the maintenance of bonds between them and users. However, hiring through private institutions allows greater agility in the recruitment of professionals, but carries the risk of precariousness of labor ties and workers’ dissatisfaction, which may affect the quality of care9898. Jorge MSB, Guimarães JMX, Nogueira MEF, Moreira TMM, Morais APP. Gestão de recursos humanos nos centros de atenção psicossocial no contexto da Política de Desprecarização do Trabalho no Sistema Único de Saúde. Texto Context - Enferm 2007; 16(3):417-425.. However, even with the advantage of continued care provided by a public service, maintaining a fully functioning and adequate team when inserted in an underfunded health system is quite a challenge, as we have seen in Brazil7373. Paim J, Travassos C, Almeida C, Bahia L, Macinko J. The Brazilian health system: history, advances, and challenges. Lancet 2011; 377(9779):1778-1797..

Conclusion

In addition to a product of technical and institutional decisions, health policies are the result of successive mediations between different agents, until their operational expression in terms of services or programs occurs. Thus, the legal and normative framework we described and compared in this study represents only part of this picture. Each of the countries surveyed organized mobile service according to their respective economic and political context, their health systems and the way in which the issue of PIH has been shaped in each of these societies. However, the comparative perspective allowed us to point out the main elements that underpin interventions of this nature.

The objective of improving access, establishing multiprofessional teams, outreach and care in addressing substance abuse are common to all three initiatives, suggesting an essential axis in PIH care. However, we identified a divergence between care strategies and resources – on the one hand, primary healthcare and compulsory use of a vehicle, and on the other, care limited to harm reduction actions with optional vehicle use. There is greater potential to reduce access time and ensure continuity of care if itinerant teams can provide primary healthcare actions combined with in situ harm reduction actions, as proposed by Brazilian and U.S. strategies, resulting in greater equity. However, offering all the care possible on the street or specifying services only for PIH may lead to lower attendance of this group in the traditional units, generating a segregating care circuit9999. Lester H, Wright N, Heath I. Developments in the provision of primary health care for homeless people. Br J Gen Pr 2002; 52(475):912.. Moreover, the excess of team assignments associated with the fragile working conditions resulting from the situations found in the streets can lead to the simplification of tasks by the workers, and reduction of what could be offered to service users, mechanizing care in PHC100100. De Paula PP. Saúde mental na atenção básica: política, trabalho e subjetividade. São Paulo: Universidade de São Paulo; 2011.,101101. Lipsky M.

The U.S. health system surprisingly presented proposals for PIH care with greater integration into primary healthcare, when compared to the Portuguese initiative, which is inserted in a system guided by the primary model. The U.S. also indicated a better introduction of health actions in the intersectoral framework6161. United States of America. United States Interagency Council on Homelessness. Opening Doors: Federal strategic plan to prevent and end homelessness. Washington D.C.: United States Interagency Council on Homelessness; 2015. in synergy with measures to improve access through the ACA6060. United States of America. Patient Protection and Affordable Care Act. Washington D.C.; 2010..

The main aspects of each country studied stem from a bibliographical review and analysis of the legal and normative framework. However, new methodological approaches and further evaluations would be necessary to identify how the aspects identified materialize in the daily practice.
