Access to Primary Health Care by older adults from rural areas in Southern Brazil

ABSTRACT

OBJECTIVE

To characterize the access and use of health services considered reference among the older rural population from a municipality in southern Brazil, whose rural area has full coverage of the Family Health Strategy (FHS), investigating factors associated with the choice of the Basic Family Health Unit (BFHU) as reference.

METHODS

This is a cross-sectional study conducted in 2017 with systematic sampling of rural households in the municipality of Rio Grande (RS) using a standardized in-house questionnaire. We performed descriptive analyses of sociodemographic profile, type of reference service chosen, and reasons for choosing/using the prime-choice service and the nearest BFHU. Poisson regression was used to investigate factors associated with the type of reference service chosen.

RESULTS

Among the 1,030 older adults who participated in the study, 61.4% considered the BFHU a prime choice/reference service mostly due to its proximity (82.6%); the others sought other places due to a greater ease (34.6%) and resoluteness (52.6%). Almost ⅔ of the respondents sought care at the BFHU during the last year, and the reasons differed among those who considered the unit as reference (chronic disease) and those who sought another place (procedures). We also found that the lower the age, income, education, and household-unit distance, the greater the likelihood of the older adult considering the nearest BFHU as reference service.

CONCLUSIONS

The FHS has reached the vulnerable older rural population, approaching an equitable public health system. However, further evaluations are necessary to verify the quality and adequacy of care, given that social structure, enabling factors (such as economic condition), and possible beliefs regarding health still establish the standards for choosing a service.

RESUMO

OBJETIVO

Caracterizar o acesso e utilização de serviços de saúde considerados como referência pela população rural idosa de um município do sul do Brasil, com cobertura de 100% da área rural pela Estratégia Saúde da Família (ESF), investigando os fatores associados à escolha da Unidade Básica de Saúde da Família (UBSF) como serviço de referência.

MÉTODOS

Estudo transversal com amostragem sistemática dos domicílios da área rural do município de Rio Grande (RS), realizado em 2017, através de questionário padronizado, aplicado em domicílio. Foram realizadas análises descritivas referentes a perfil sociodemográfico; tipo de serviço de referência escolhido; e motivos de escolha/utilização do serviço de primeira opção e da UBSF mais próxima. Realizou-se regressão de Poisson para investigar fatores associados ao tipo de serviço de referência escolhido.

RESULTADOS

Participaram do estudo 1.030 idosos, dos quais 61,4% indicaram a unidade básica como serviço de primeira opção/referência. Enquanto aqueles que escolheram ser atendidos na UBSF o faziam principalmente em razão da proximidade (82,6%), os demais procuraram outros locais pela percepção de maior facilidade (34,6%) e resolutividade (52,6%). Quase ⅔ dos entrevistados buscaram atendimento na UBSF no último ano, e os motivos foram diferentes entre aqueles que consideravam a unidade como referência (doença crônica) e aqueles que procuravam outro local (procedimentos). Além disso, quanto menor a idade, renda, escolaridade e distância residência-unidade, maior a probabilidade do idoso considerar a UBSF mais próxima como serviço de referência.

CONCLUSÃO

A ESF tem conseguido atingir a parcela rural idosa em situação de vulnerabilidade, indo ao encontro de um sistema de saúde público equitativo. Todavia, novas avaliações para averiguar adequação e qualidade do atendimento se fazem necessárias, visto que estrutura social, fatores capacitantes (como condição econômica) e possíveis crenças sobre saúde ainda definem o padrão de escolha do serviço.

INTRODUCTION

Broader concepts and practices have been rebuilding the notion of health care over time. The Alma-Ata11. International Conference on Primary Health Care; 1978 Sept 6-12; Alma- Ata, URSS.

declaration internationally broaden the focus on primary health care (PHC). In Brazil, PHC is being developed by the Family Health Strategy (FHS) – a multidisciplinary work that functions as the gateway to the health care system by the action of teams that assume health responsibility for populations of specific territories22.

. Despite the challenges in relocating traditional basic units to the FHS, the access to primary care increased about 450% between 1981 and 200877. Paim J, Travassos C, Almeida C, Bahia L, Macinko J.

Evaluation is an essential component in the constant expansion and restructuring of health systems, especially regarding the way users access services55.

. Defining the concept of “access” is a complex task, and no unanimity has been reached among scholars in the field. Its meaning varies according to time and context, but the prevailing one is associated with health services supply capacity1111. Travassos C, Martins M. Uma revisão sobre os conceitos de acesso e utilização de serviços de saúde. Cad Saude Publica. 2004;20 Supl 2:S190-8. https://doi.org/10.1590/S0102-311X2004000800014
https://doi.org/10.1590/S0102-311X200400...
.

Evaluating access is even more important when it comes to populations that historically have faced greater barriers to accessing adequate care, such as older rural residents1212. Shimizu HE, Trindade JS, Mesquita MS, Ramos MC. Avaliação do Índice de Responsividade da Estratégia Saúde da Família da zona rural.

. For presenting greater needs, this group tends to use health services more often88. Arruda NM, Maia AG, Alves LC.

. In turn, the low variety or quality of locally available services may cause treatment seeking delays or in farther services, resulting in greater physical, emotional, and financial attrition1717.

.

Despite the vulnerability of older rural populations and the complexity of developing a care plan, few studies have directed efforts to this portion of the population44.

. Given the specific needs and limitations of this group, it is pertinent to investigate how they seek for health services and possible difficulties they encounter. Considering that, this study aims to characterize the access and use of health services considered reference among older adults living in a rural area with full FHS coverage from a municipality in southern Brazil, investigating factors associated with the choice of the Basic Family Health Unit (BFHU) as reference.

METHODS

This research collected data on the profile of access and use of health services by older residents (individuals aged 60 years or older) of the rural area of Rio Grande (RS). The data represent a cut-off of the cross-sectional study Saúde da População Rural Rio-Grandina (Health of the Rio-Grandina Rural Population), conducted by the Graduate Program in Public Health of the Universidade Federal do Rio Grande (FURG). The study investigated health indicators and the pattern of morbidity, access, and use of health services by children up to 5 years old, women of childbearing age, and older residents of the rural area of Rio Grande.

The municipality of Rio Grande is located within the state of Rio Grande do Sul, 350 km from the capital Porto Alegre, and has approximately 200 thousand inhabitants. Of these, 5.5% (about 8,225 individuals) lived in rural areas at the time of the cross-sectional study, and 13.1% among those were older adults1919. Instituto Brasileiro de Geografia e Estatística. Censo Demográfico, 2010. Rio de Janeiro: IBGE; 2011.. Regarding Public Health Network, 53% of the municipality total area was attended by the FHS, reaching 100% in the rural area. The rural population disposed of 10 family health teams in eight BFHU (one of them functioning as an emergency service, open 24 hours) supported by two Expanded Family Healthcare Centers (EFHC).

Minimum sample size was calculated to estimate the prevalence of the dependent variable (considering 95% confidence level, 70% frequency for estimating results, 3-percentage point margin of error, and 1.5 design effect) and its associated factors (considering 80% power, 10% addition for losses and refusals, and 15% for controlling confounding factors), reaching the number of 857 individuals.

Households within the 23 rural census sectors of the municipality were interviewed between April and November 2017, with a systematic interval of one household for every four sampled, covering approximately 80% of the populations of interest. Households without individuals in the age groups of interest were not considered eligible, but when residents of sampled households fit into the age groups of interest, all eligible individuals were interviewed. Older adults who were institutionalized by the interview period were excluded from the study. Caregivers were interviewed whenever individuals within the age group of interest were physically or mentally incapable of answering the questionnaire.

Data was collected using a standardized questionnaire. Usage profile was analyzed according to the service considered reference by the interviewee through the question: “When you need health care, which is the first service that you go to?”. Response options were posteriorly categorized into “reference BFHU” (the closest unit to participants’ household) or “other service”, including hospitals, private practice or medical offices affiliated to health insurance plans, and services located in other municipalities.

Independent variables were: gender (male and female); age (60 to 69 years; 70 to 79 years; 80 years or older), skin color (white or black/brown/Asian/native American), education level (0 to 4 years; 5 to 8 years; 9 years and over), family income (in tertiles), living alone (no or yes), have a health insurance plan (no or yes), and distance from the nearest BFHU (< 1 km; 1 to 2.9 km; 3 to 5.9 km; 6 to 9.9 km; 10 km or more). The following health status-related variables were also investigated: presenting chronic disease (no or yes) and self-reported health status (good/very good; fair; poor/very poor).

Descriptive statistical analyses of the sample sociodemographic profile, the type of reference service chosen, and the reasons for choosing and using it were performed in the Stata 14.1 statistical software. Poisson regression with robust adjustment for variance was used to investigate factors associated with the type of reference service chosen.

For the adjusted analysis, we developed a conceptual model with hierarchical levels2020. Victora CG, Hutlly SR, Fuchs SC, Olinto MT. The role of conceptual frameworks in epidemiological analysis: a hierarchical approach. Int J Epidemiol. 1997;26(1):224-7. https://doi.org/10.1093/ije/26.1.224
https://doi.org/10.1093/ije/26.1.224...
considering the three categories of factors influencing access to health services99. Almeida APSC, Nunes BP, Duro SMS, Facchini LA. Determinantes socioeconômicos do acesso a serviços de saúde em idosos: revisão sistemática. Rev Saude Publica. 2017;51:50. https://doi.org/10.1590/S1518-8787.2017051006661

identified by Aday and Andersen2121. Aday LA, Andersen R. A framework for the study of access to medical care. Health Serv Res. 1974 [cited 2019 Dec 18];9(3):208-20. Available from: https://www.ncbi.nlm.nih.gov/pubmed/4436074

: predisposing factors (individual characteristics, prior to the health problem, influencing subject’s propensity to use health services), enabling factors (means that allow care provision), and health needs (related to disease level). Thus, the model employed in the analyses was: 1) distal level: predisposing factors (gender, age, and skin color); 2) intermediate level: enabling factors (education, family income, living alone, having health insurance, and distance from the nearest BFHU); and 3) proximal level: health needs (chronic disease and self-reported health status). The model suffered adjustments for potential confounding factors of the same or higher level, considering p value < 0.20 as the limit to maintain variables in the final model, for controlling positive confusions.

The research project was approved by the Research Ethics Committee of the Universidade Federal do Rio Grande under Opinion No. 51/2017, process 23116.009484/2016-26. All older adults surveyed or their respective caregivers (in case of limitation of the participant) signed the informed consent form.

RESULTS

Of the 1,351 older adults living in the rural area of Rio Grande, 83.7% (n = 1,131) were sampled for the study, reaching a final number of 1,030 respondents (8.9% of losses and refusals). The sample comprised mostly men, between 60 and 69 years old, white, with 0 to 4 years of education, and living with at least one more person. Only ⅓ of the participants had private health insurance and only 14.9% lived less than one kilometer away from the nearest Basic Family Health Unit (BFHU – Table 1). Median monthly household income was R$1,874. 00 (IQQ = R$1,000.00–R$2,000.00).

Table 1
Description of the older rural population sample from the municipality of Rio Grande, Rio Grande do Sul, Brazil, 2017 (n = 1,030).

Regarding seek for health services, almost ⅔ of the respondents (61.4%) considered the BHFU closest to their residence its prime choice/reference service. By stratifying the analyses between the reference BHFU and other care sites, we found different reasons for choosing the service (Table 2). While those who preferred to be attended at their reference BHFU did so mainly due to its proximity from their households, the others underwent follow-up in other services due to habituation, knowing the greater ease and resoluteness of these services in providing the necessary care.

Table 2
Reasons for seeking and choosing the reference health service among the older ruralpopulation from the municipality of Rio Grande, Rio Grande do Sul, Brazil, 2017 (n = 1,018).

As for reasons that led users to seek care, treating already-established diseases (chronic and acute) was the main reason in both groups. Just over half of participants with chronic disease sought care at their reference service (although 79.2% reported presenting with some chronic disease, only 44% sought care).

Tables 3 and 4 outline data on the demand for care at the BHFU closest to older participants’ residences in the 12 months prior to the survey; that is, the BHFU considered as reference unit by the municipal healthcare management. In total, 60.1% of the interviewees sought care at the site, with higher demand among those who considered it as their reference service (75% versus 36%); 87.7% of those evaluated the service positively, with no significant difference among groups.

Table 3

Table 4
Data on reasons for seeking or not seeking care at the reference BFHU in the 12 months prior to the survey for the older rural population from the municipality of Rio Grande, Rio Grande do Sul, Brazil, 2017.

The reasons that led users to seek care at the respective BHFU differed between participants considering it their prime option and those considering another site as reference: while the former had more general reasons (disease treatment, assessment, examinations), the others sought the BHFU more frequently to undergo clinical procedures.

As for those who did not seek BHFU in the last 12 months (n = 405), the reasons likewise differed between the two groups. Those who considered the BHFU as prime option reported feeling no need to seek some type of care (84.2% versus 35.2%) whereas the others reported preferring another place, which they considered more resolute for obtaining the appropriate care (42.1% versus 8.2%).

Table 5 shows factors associated with choosing the BHFU as reference service, indicating that the lower the age, income, education, and household-unit distance, the greater the likelihood of the older adult considering the nearest BFHU as reference service. Having a private health insurance plan decreased the probability of choosing the BHFU by 25%, and characteristics associated with participants’ health needs were not statistically associated with the choice (Table 5).

DISCUSSION

We found that almost ⅔ (61.4%) of the older residents of the rural area of the municipality of Rio Grande considered the Basic Family Health Unit (BHFU) closest to their residences as a reference health service. The lower the age, education, income, and household-unit distance, the greater the likelihood of the Primary Health Care (PHC) service being chosen as prime option by users. We found a higher percentage of older adults who considered the PHC as a customary service than that reported by another study conducted in Brazil – especially regarding older (36.2%) and rural population (49.2%)2222.

.

Reference services have been positively associated with improvements in users’ health condition and system efficiency, since longitudinal monitoring prevents diseases onset and progression, avoiding the overload of emergency services and consultations with specialists for preventable causes1515.

. Moreover, reference services enable the development of a trust relationship between health team and user, strengthening adherence to treatment22. Ministério da Saúde (BR).

Following Aday and Andersen’s categorization2121. Aday LA, Andersen R. A framework for the study of access to medical care. Health Serv Res. 1974 [cited 2019 Dec 18];9(3):208-20. Available from: https://www.ncbi.nlm.nih.gov/pubmed/4436074
https://www.ncbi.nlm.nih.gov/pubmed/4436...
, the main health needs that lead older adults to seek the BFHU and other reference services were already-established diseases (chronic and acute), underlining a similar needs profile between both groups. The higher demand for public PHC services may reflect government annual efforts to immunize older adults against influenza through campaigns that, in 2018, exceeded 97% vaccinated individuals and reached 99.39% in 20192525.

The literature shows that individuals presenting with chronic diseases have a greater demand for healthcare55. Silva KF, Pucci VR, Weiller TH, Mayer BLD, Concatto MEP.

https://doi.org/10.1590/1413-81232018236...
. However, as already indicated by another study conducted in Brazil1414. Travassos C, Viacava F. Acesso e uso de serviços de saúde em idosos residentes em áreas rurais, Brasil, 1998 e 2003. Cad Saude Publica. 2007;23(10):2490-502. https://doi.org/10.1590/S0102-311X2007001000023
https://doi.org/10.1590/S0102-311X200700...
, the percentage of service use is still inadequate to users’ needs, given that 40% of participants who reported having some chronic condition did not seek care in the past year.

The groups were quite similar regarding enabling factors, although service supply differed between them. Emergency services and private/affiliated medical offices have a more responsive nature, usually meeting only demands of already sick users; in turn, PHC services aim to develop, besides treatment and rehabilitation, practices of disease prevention, health promotion, and popular participation22. Ministério da Saúde (BR). Portaria nº 2.436, de 21 de setembro de 2017.

Diário Oficial da União. 22 ago 2017; Seção 1:68..

However, these latter purposes did not excel among reasons for seeking for BFHU, which may be explained by the health beliefs and behaviors of the studied population – for example, users and staff unfamiliarity or disengagement regarding PHC broader goals, not deemed as priority1212.

The high percentage of older adults who reported not having sought chronic illness care, the way they dealt with it, and its possible stigmas may also be implied within such beliefs and behaviors1515.

.

Although the Brazilian Public Health System provides free service for everyone, enabling an easier access to care, respondents with private health insurance or better economic conditions tended to choose other health services as prime option, possibly meaning (as previously identified in the literature) that older adults seek other care sites when they have the means to access more expensive services1717.

.

Regarding education, the association between lower education and choosing the BHFU as prime option may be related to a greater general self- and health-knowledge, as well as to higher self-medication rates, allowing users to better identify an appropriate service for their health status or decreasing their understanding of the need for follow-up1414. Travassos C, Viacava F. Acesso e uso de serviços de saúde em idosos residentes em áreas rurais, Brasil, 1998 e 2003.

.

Another enabling factor is health services structure and organization: while distance was decisive for choosing the BFHU as a reference service, those who sought other care sites indicated other elements – such as resoluteness (“offers the treatment I need”), ease and speed in care provision, and confidence in the treatment/professional. Several studies approached the influence of distance to the desired care site, showing that greater distances entail lower service use33.

, especially among individuals with low mobility, few available service options, and little or no access to means of transportation44. Garbaccio JL, Tonaco LAB, Estêvão WG, Barcelos BJ.

https://doi.org/10.1186%2Fs12913-016-183...
. Yet, proximity is not the only factor to guarantee access, as rural residents may be willing to travel longer distances (despite the higher costs and greater physical and emotional attrition) when they assume they would not receive the most suitable care near their residences1010.

.

We found predisposing factors to be only associated with age. Older adults of a younger age may have better mobility and functional capacity, enabling them to actively seek care beyond home visits; but older individuals may require more specific and specialized care, unavailable at primary healthcare level55. Silva KF, Pucci VR, Weiller TH, Mayer BLD, Concatto MEP. O acesso do idoso na Atenção Primária à Saúde: uma revisão integrativa.

https://doi.org/10.1590/1980-54972018001...
.

Reasons that lead individuals not to seek service are also important, complementing their perceived organization of the site. Among those who consider the BFHU as the prime care option, the main reason not to seek for it was feeling no need for any type of care, similar to that identified by other studies55. Silva KF, Pucci VR, Weiller TH, Mayer BLD, Concatto MEP. O acesso do idoso na Atenção Primária à Saúde: uma revisão integrativa. Rev APS. 2018;21(1):122-33. https://doi.org/10.34019/1809-8363.2018.v21.15911
https://doi.org/10.34019/1809-8363.2018....
. However, perceived non-need is a questionable aspect given that our study population demands greater care and, consequently, more frequent qualified assessment of their actual health status. FHS principles are particularly relevant in this context, for it strives for an active search and longitudinal follow-up through family monitoring and home visits conducted by community health agents and technical teams22. Ministério da Saúde (BR). Portaria nº 2.436, de 21 de setembro de 2017. Aprova a Política Nacional de Atenção Básica, estabelecendo a revisão de diretrizes para a organização da Atenção Básica, no âmbito do Sistema Único de Saúde (SUS). Diário Oficial da União. 22 ago 2017; Seção 1:68.,1818. Macinko J, Andrade FB, Souza-Júnior PRB, Lima-Costa MF. Primary care and healthcare utilization among older Brazilians (ELSI-Brazil). Rev Saude Publica. 2018;52 Supl 2:6s. https://doi.org/10.11606/s1518-8787.2018052000595
https://doi.org/10.11606/s1518-8787.2018...
.

Being a cross-sectional research and thus susceptible to reversing causality, this research is not intended at investigating cause-effect relationships between the presented variables. This study has some limitations: (1) data related to the service organization was provided only by users, without directly contacting the care services; (2) household-unit distance was also provided by respondents, generating data not as accurate as it would be if collected by georeferencing, as well as a high loss of answers, as some respondents were unable to provide such information.

Given that access is strongly associated with individual perceptions1515. Pedraza DF, Nobre AMD, Albuquerque FJB, Menezes TN. Acessibilidade às Unidades Básicas de Saúde da Família na perspectiva de idosos. Cienc Saude Coletiva. 2018;23(3):923-33. https://doi.org/10.1590/1413-81232018233.11702016
https://doi.org/10.1590/1413-81232018233...
(i.e., perceived ease of access), the use of other sources to complement data would enrich results. Yet, the exclusive focus on the user is highly relevant and does not invalidate our findings, given that their perceived health needs allow anticipating demands and function as an underlying basis for developing public policies2929. Antunes JLF, Chiavegatto Filho ADP, Duarte YAO, Lebrão ML. Desigualdades sociais na autoavaliação de saúde dos idosos da cidade de São Paulo. Rev Bras Epidemiol. 2018;21 Supl 2:e180010. https://doi.org/10.1590/1980-549720180010.supl.2
https://doi.org/10.1590/1980-54972018001...
.

As aforementioned, the FHS reached a great amount of the older rural population, especially those in vulnerable situations, approaching an equitable public health system. However, ⅓ of the study group sought other services for follow-up despite having access to BFHU; that is, even with FHS full coverage, social structure, enabling factors (such as economic condition), and beliefs about health still establish the standards for choosing a service.

This finding elucidates the urge for continuous strengthening of the care network for those with greater health needs, as well as spotlighting the profiles of users who did not seek the service. For that, we may develop preventive and health promotion activities targeting individuals who do not perceive the need for follow-up, as well as adapt BFHU structure and organization to attract those who seek another care site. These strategies require new evaluations by managers, researchers, and professionals for expanding knowledge on this matter in different contexts and assessing the adequacy and quality of the service provided.
