ABSTRACT

OBJECTIVE

To evaluate the access to medicines in primary health care of the Brazilian Unified Health System (SUS), from the patients’ perspective.

METHODS

This is a cross-sectional study that used data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Services, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines), conducted by interviews with 8,591 patients in cities of the five regions of Brazil. Evaluation of access to medicines used concepts proposed by Penshansky and Thomas (1981), according to the dimensions: availability, accessibility, accommodation, acceptability, and affordability. Each dimension was evaluated by its own indicators.

RESULTS

For the “availability” dimension, 59.8% of patients reported having full access to medicines, without significant difference between regions. For “accessibility,” 60% of patients declared that the basic health unit (UBS) was not far from their house, 83% said it was very easy/easy to get to the UBS, and most patients reported that they go walking (64.5%). For “accommodation,” UBS was evaluated as very good/good for the items “comfort” (74.2%) and “cleanliness” (90.9%), and 70.8% of patients reported that they do not wait to receive their medicines, although the average waiting time was 32.9 minutes. For “acceptability,” 93.1% of patients reported to be served with respect and courtesy by the staff of the dispensing units and 90.5% declared that the units’ service was very good/good. For “affordability,” 13% of patients reported not being able to buy something important to cover expenses with health problems, and 41.8% of participants pointed out the expense with medicines.

CONCLUSIONS

Results show 70%–90% compliance, which is compatible with developed countries. However, access to medicines remains a challenge, because it is still heavily compromised by the low availability of essential medicines in public health units, showing that it does not occur universally, equally, and decisively to the population.

INTRODUCTION

Access to medicines is an indispensable component for populations to have a universal and equal health coverage, with problem-solving capacity and quality, being recognized by the United Nations as one of the five indicators related to advances in ensuring the right to health⁹9.

Brazil has adopted strategies aiming to expand access to safe and effective medicines, by regulations of great importance to the health system. The legal framework to ensure access to medicines has been established with the law 8080/1990⁵5. Brasil. Lei nº 8.080 de 19 de setembro de 1990. Dispõe sobre as condições para a promoção, a organização e o funcionamento dos serviços correspondentes e dá outras providências. Diario Oficial Uniao. 20 set 1990; Seção 1:18055., which established the right of all citizens to integral therapeutic care, including pharmaceutical services. However, after numerous cases of quality deviations, forgeries, and inefficient sanitary control, a National Medicines Policy was elaborated and published in 1998, to ensure the access to essential medicines. This policy established the adoption and implementation of guidelines and priorities for government action, consisting in the reorientation of Pharmaceutical Services (PS), adoption of the Relação Nacional de Medicamentos Essenciais (RENAME – National List of Essential Medicines) and other items¹¹11. Ministério da Saúde (BR). Portaria nº 3.916 de 30 de outubro de 1998. Aprova a Política Nacional de Medicamentos. Diario Oficial Uniao. 10 nov 1998; Seção 1:18. [cited 2014 Dec 15].

http://bvsms.saude.gov.br/bvs/saudelegis... . In 2004, the National Health Council also reaffirmed, by the Política Nacional de Assistência Farmacêutica (PNAF – National Policy of Pharmaceutical Services), the need for the Brazilian Unified Health System (SUS) to adopt actions for the expansion of access to medicines, development and local production of supplies and medicines according to the Brazilian needs, promotion of rational use, and qualification of the health professionals involved with medicines¹²12. Ministério da Saúde (BR), Conselho Nacional de Saúde. Resolução nº 338, de 06 de maio de 2004. Aprova a Política Nacional de Assistência Farmacêutica. Brasília (DF); 2004 [cited 2014 Dec 15]. Available from: http//www.saude.gov.br/doc/resolucaocns338/cns.html

Ensuring access to medicines is particularly important in the context of Primary Health Care (PHC), which is characterized as an entry in SUS, and it is part of the process of promotion, recovery, and prevention of some of the most prevalent diseases in the population.

In 2015, Brazil had more than 40 thousand basic health units (UBS) in operation, with a potential coverage of about 70% of the Brazilian population^aaSAGE - Sala de Apoio à Gestão Estratégica. Unidade Básica de Saúde. Brasília (DF): Ministério da Saúde; 2015 [cited 2015 Mar 23]. Available from: http://sage.saude.gov.br/.. Therefore, the evaluation of access to medicines is essentially important, since a large portion of the Brazilian population, mainly that with lower income, relies on public programs and, in particular, on medicines offered by the Basic Component of SUS Pharmaceutical Services⁸8.

Access to medicines depends on a complex network of public and private actors, who play different roles depending on the economic, political, and social context of several countries which encourage conditions for this access to happen¹⁴14. Organização Pan-Americana da Saúde. Avaliação da Assistência Farmacêutica no Brasil: estrutura, processo e resultados. Brasília (DF): OPAS, Ministério da Saúde; 2005 [cited 2017 Feb 10]. (Série Medicamentos e Outros Insumos Essenciais para a Saúde). Available from: http://bvsms.saude.gov.br/bvs/publicacoes/avaliacao_assistencia_farmaceutica_estrutura_resultados.pdf
http://bvsms.saude.gov.br/bvs/publicacoe... , and these countries must work together and gather political, social, and multidisciplinary efforts toward solutions.

In the academic field, the term “health services accessibility” presents a striking multiplicity of concepts and approaches. Conceptually, “health accessibility” has been used to represent different dimensions over time. The first proposals mapped by the World Health Organization in the 1970s suggested a strong connection of access with geographical accessibility, availability, and affordability. Latest literature seeks to address less tangible aspects, such as cultural, educational, and socioeconomic ones, incorporating the conceptual dimension of acceptability in the analyses²⁰20. Sanchez RM, Ciconelli RM. Conceitos de acesso à saúde. Rev Panam Salud Publica. 2012;31(3):260-8. https://doi.org/10.1590/S1020-49892012000300012
https://doi.org/10.1590/S1020-4989201200... .

The development of a measuring instrument of access that considers the specificities of various health systems, as well as the context in which it is located, is a great challenge, because of the difficulty of measurement and variations of the health systems⁷7. Emmerick ICM. Dimensões e determinantes do acesso a medicamentos em três países da América Central [tese de doutorado]. Rio de Janeiro: Escola Nacional de Saúde Pública Sergio Arouca; 2011.. Penchansky and Thomas¹⁷17. Penchansky R, Thomas JW. The concept of access: definition and relationship to consumer satisfaction. Med Care. 1981;19(2):127-40. (1981) have defined access as the “degree of fit between clients and system,” and highlighted that a full analysis of access must include attributes of patients’ and health services’ needs. This analysis comprises a multidimensional concept, covering specific dimensions that include: availability, accessibility, accommodation, affordability, and acceptability.

Penchansky and Thomas¹⁷17. Penchansky R, Thomas JW. The concept of access: definition and relationship to consumer satisfaction. Med Care. 1981;19(2):127-40. based themselves on the observation of the pharmaceutical services model of North America and Western Europe, in which medicines were obtained in private community pharmacies, with or without funding by a third actor (public programs or private insurance). Despite differences between logistic models of pharmaceutical services, the observations and dimensions used by these authors are useful and have been used to evaluate and characterize access to medicines in different countries.

It has been estimated that, at the beginning of the 21^st century, one out of three people in the world would not have access to essential medicines, and, in low and middle income countries, this proportion could reach 50%¹⁶16.

This study aimed to verify the access to medicines within the PHC of SUS, from the perspective of the patient, employing the multidimensional concept of access established by Penchansky and Thomas¹⁷17. Penchansky R, Thomas JW. The concept of access: definition and relationship to consumer satisfaction. Med Care. 1981;19(2):127-40..

METHODS

PNAUM is a cross-sectional, exploratory, evaluative study, consisting of an information gathering in a representative sample of primary health care services in Brazilian cities. Several study populations were considered in the sampling plan, with samples stratified by regions, which constitute the study domains¹1. Álvares J, Alves MCGP, Escuder MML, Almeida AM, Izidoro JB, Guerra Junior AA, et al. Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos: métodos. Rev Saude Publica. 2017;51 Supl 2:4s. https://doi.org/10.11606/S1518-8787.2017051007027
https://doi.org/10.11606/S1518-8787.2017... . In-person interviews were held with patients, doctors, and those responsible for delivering medicines in SUS primary health care services, in addition to observation of the pharmaceutical services facilities and telephone interviews with administrators responsible for pharmaceutical services in the cities.

For randomly selecting the patients’ sample, we used sampling in three stages: city, health service, and patient. The organizers defined that 1,800 patients would be interviewed by region of the country. Considering the occurrence of a non-response percentage of 15%, 2,100 patients were randomly selected. In each region, this number of patients was proportionally distributed by the strata (city and health service), according to the frequency of services sampled in each of them. Patients were addressed within health services, while waiting for a medical appointment. The selection of patients in each service cannot be performed from patients’ listings. Thus, criteria for the selection of patients were established, making the selection be as close as possible to a random selection. Data were collected between July and December 2014.

The evaluation of access to medicines was conducted by the data obtained from interviews with patients, based on the five dimensions of access: availability, accessibility, accommodation, acceptability, and affordability. Each dimension was evaluated by its own indicators, as Table 1 shows.

The evaluation of the “availability” dimension was made by the question: “In the last three months, how often did you get the medicines that you sought in SUS dispensing units?”, and the variable was categorized into full access (always), partial access (repeatedly, sometimes, or rarely), and no access (never).

“Accessibility” was evaluated by asking patients about how far and how easy/very easy it was for them to get to the UBS, whether it was possible to go walking, and about the existing signaling to find the dispensing unit in the UBS.

“Accommodation” was observed by the patients’ perceptions regarding comfort, cleanliness, waiting time, and opening hours of the UBS.

“Acceptability” was analyzed by the patients’ perception about the quality of service, specifically concerning courtesy, respect, and privacy in the care.

“Affordability” was examined by asking patients if their family stopped buying something important to cover health expenses, and whether these expenses were related to the purchase of medicines.

Data were analyzed using the software SPSS®, version 22. All analyses considered the sampling weights and structure of the complex plan. The results show representativeness for the geographic regions of Brazil. Tables of distribution of frequencies for categorical variables and of measures of central tendency for numerical variables were built. To evaluate the statistical association, Student’s t test was conducted for numeric variables, and Pearson correlation test was held for categorical variables. The significance level adopted was p < 0.05.

PNAUM was approved by the Research Ethics Committee, by Opinion no. 18947013.6.0000.0008. All participants signed the informed consent form.

RESULTS

Of the 8,803 patients interviewed in the UBS of the five regions of Brazil, 8,591 (97.5%) answered to the questionnaire items related to the dimensions “accessibility” and “affordability,” interpreted as stopping to buy something important to cover health expenses. Only patients who have used/searched medicines in the SUS dispensing units (65.4%, n = 5,758) answered to the items about the other dimensions evaluated.

Table 1 presents the consolidation of the indicators on the various dimensions of access in Brazil. Table 2 shows a detailed analysis by Brazilian region of the patients’ perception about access to medicines in SUS Primary Health Care, classified by dimension.

In “availability” dimension, regarding the item “access to medicines in SUS dispensing units,” it was found that 59.8% of patients reported full access to medicines in SUS, which was higher in the Southeast (64.3%) and lower in the Midwest (46.3%). “Partial access” and “no access” to medicines in the SUS corresponded respectively to 35.9% and 4.3% of the patients interviewed. Statistically significant differences were not observed between regions of the Country (p = 0.167).

In “accessibility” dimension, 59.5% of patients declared that the “UBS is not far from their house,” and most patients (83.0%) considered that it is easy or very easy to get to the unit, with about 64.5% of them going to the health unit walking. Still regarding the means of transport used to go to the units, a higher proportion of patients in the Southeast region reported that they go walking (70.0%), while in the Midwest this proportion was lower (52.6%). The South region presented higher frequency of patients who use car or motorcycle (34.5%) and the Northern region, the lowest (22.2%). Statistically significant differences were found between the regions (p < 0.05). Concerning the evaluation of the existing signaling, most patients (88.5%) declared it was very easy/easy to find the SUS dispensing unit.

In the “accommodation” dimension, the comfort and cleanliness of the SUS dispensing units were evaluated as very good/good by 74.2% and 90.9% of patients, respectively. For comfort, statistically significant differences were observed between regions (p < 0.05); in the Southeast region, 82.2% of patients evaluated SUS units as very good, and in the Northeast, 64.2% and 66.7%, respectively.

The average waiting time to receive medicines in SUS dispensing units was 32.9 minutes (min), with the longest time reported in the Southeast region (59.8 min) and the shortest, in the North (13.3 min). Nevertheless, 70.1% of patients reported not waiting to receive their medicines.

It was found that 85.8% of patients evaluated the opening hours of the UBS as very good/good, with the highest proportion in the Southeast region (89.8%) and the lowest in the Northeast (80.5%), showing statistically significant differences between regions (p < 0.05).

In “acceptability” dimension, 93.1% of patients reported to be served with respect and courtesy by the staff of the SUS dispensing units. The service was well evaluated: 90.5% of patients declared the service of these units was very good/good; but patients of the North region (85.2%) were least satisfied with it (p < 0.05). Regarding privacy in the care, a percentage of satisfaction of 66.4% was observed, with 73.1% in the Southeast region and 56.8% in the Midwest (p < 0.05).

In “affordability” dimension, 13% of patients in Brazil reported not being able to buy something important to cover expenses with a health problem, and 41.8% of them declared that it was to buy medicines. Statistically significant differences were not found between the regions.

DISCUSSION

The multidimensional evaluation of access to medicines according to the patients’ perspective is vitally important to identify aspects and factors that go beyond the simple provision of medicines. The perspective of the five dimensions, adapted from Penchansky and Thomas¹⁷17. Penchansky R, Thomas JW. The concept of access: definition and relationship to consumer satisfaction. Med Care. 1981;19(2):127-40. (1981), of this study allowed us to know the perception of patients, who are the main beneficiaries of SUS and to whom health policies must be aimed at¹⁰10.

https://doi.org/10.1590/S1413-8123201200... .

“Availability” dimension is still recognized as the main obstacle to access in Brazil. It is a problem that persists in the Country, and several studies carried out in the public sector have found problems with physical availability, acquisition, or lack of medicines¹1.

https://doi.org/10.1590/S0080-6234201200... . In this study, we observed low levels of availability of medicines in the PHC (46.3% to 64.3%) among patients who have declared to have full access to medicines by the SUS dispensing units, which may impair the integrality of health care.

The highest frequency of patients who reported full access was in the Southeast, and the smallest, in the Midwest, confirming the findings of Boeing et al.⁴4. Boing AC, Bertoldi AD, Boing AF, Bastos JL, Peres KG. Acesso a medicamentos no setor público: análise de usuários do Sistema Único de Saúde no Brasil. Cad Saude Publica. 2013;29(4):691-701. https://doi.org/10.1590/S0102-311X2013000400007
https://doi.org/10.1590/S0102-311X201300... (2013) in the National Household Sample Survey of 2008. In this study, 45.3% of individuals reported having had full access (received all prescribed medicines by SUS), but with a higher proportion in the South region (48.1%) and a lower one in the North (37%).

The accessibility to dispensing units in the primary health care presents some conflicting results, according to the patients’ perspective. Although most patients declared it was easy or very easy to reach the UBS, nearly a quarter of patients reported that the UBS was far from their house. It is worth mentioning that the organization by registered population, i.e., the population of the service area of a health unit, adopted in PHC, should minimize the problems of “accessibility.” The PHC aims to ensure citizens an ordered and organized access to health systems, primarily by services of PHC found close to the houses of patients, to guarantee the integrality of the health care²²22.

A higher proportion of patients in the Southeast region declares that they go walking to the UBS, while patients of the South used car or motorcycle (p < 0.05). A study conducted with 188 patients of six UBSs in a city of Minas Gerais shows that 89.4% of patients declared to be satisfied regarding location, distance from the house, and time spent to reach the unit, besides the possibility of not needing to use means of transport²¹21. Santos SMS, Oliveira VAC, Oliveira RAC, Guimarães EAA. Estratégia Saúde da Família: qualidade da assistência sob a perspectiva do usuário. REME Rev Min Enferm. 2010 [cited 2017 Feb 10]; 14(4):499-508. Available from: http://www.reme.org.br/artigo/detalhes/143
http://www.reme.org.br/artigo/detalhes/1... . In another study conducted in two UBSs of Recife, 76% of patients (n = 1,161) were satisfied with the distance from their house to the UBS⁷7. Emmerick ICM. Dimensões e determinantes do acesso a medicamentos em três países da América Central [tese de doutorado]. Rio de Janeiro: Escola Nacional de Saúde Pública Sergio Arouca; 2011.. Concerning the quality of the signaling of the SUS medicine dispensing units, 91.3% of patients considered it was easy/very easy. However, we found no other similar studies for comparison.

For the “accommodation” dimension, most patients of this study considered the UBSs clean and comfortable. Patients in the Southeast, although being pleased with the comfort, cleanliness, and opening hours, reported having to wait about one hour on average to withdraw the medicines. A study held in a city of Minas Gerais⁶6. Chaves GC, Emmerick I, Pouvourville N, Saint-Denis T, Fonseca ASA, Luiza VL. Indicadores de uso racional de medicamentos e acesso a medicamentos: um estudo de caso. Rev Bras Farm. 2005 [cited 2017 Feb 10]; 86(3):97-103. Available from: http://rbfarma.org.br/files/pag_97a103_INDICADORES.pdf
http://rbfarma.org.br/files/pag_97a103_I... found that the average waiting time in line at the pharmacy was three minutes, a much lower value than the one found in this research.

For “acceptability” dimension, patients considered the service as good/very good and evaluated the treatment by the staff as respectful and polite. Patients in the Southeast region were the most satisfied, and those of the North, the least. Regarding privacy in the service, 15% of patients reported rarely/never having privacy, which was more common in the Midwest region. A systematic review by Nora and Junges¹³13. Nora CRD, Junges JR. Política de humanização na atenção básica: revisão sistemática. Rev Saude Publica. 2013;47(6):1186-200. https://doi.org/10.1590/S0034-8910.2013047004581
https://doi.org/10.1590/S0034-8910.20130... pointed out that the lack of appropriate physical space in the UBSs may be related to the absence of privacy in the care to patients. They also reported that the discontent of patients with the physical space, considered small, or even the lack of a waiting room, makes the waiting for care an uncomfortable experience. In this review, the comfort in the dispensing units of medicines was considered unsatisfactory.

For the “affordability” dimension, 13.0% of patients reported that they were not able to buy something important to cover health expenses. This result must be carefully seen, since patients with access problems may not be present in the health services at the time of the interview, resulting in less representation. Thus, the obtained indicator may be underestimating the extension of the economic impacts for the families due to the low availability of medicines in SUS¹⁷17. Penchansky R, Thomas JW. The concept of access: definition and relationship to consumer satisfaction. Med Care. 1981;19(2):127-40.. Despite this possible bias, medicine was considered one of the main problems that caused health spending. The same was observed in a study on Household Budget Surveys in the years 2002-2003 and 2008-2009, by the Brazilian Institute of Geography and Statistics, which found that the expenses on medicines is the main component of the health expenditures of Brazilian families. This affected more the families with less income, which clearly separated, proportionally, a greater share of family income in the acquisition of medicines⁸8.

Evaluating access to medicines in Brazil is still a major challenge, especially regarding the multiplicity of concepts and approaches on the subject. In addition to impairing the comparability of the studies, the lack of standardization between the instruments used in the evaluations causes the indicators to show discrepant results between dimensions. Results of this study on access to medicines are representative of Brazil. Evaluating the different dimensions from the perspective of patients of SUS and the consequent performance of public policies to this end provides data with implications on the management and allocation of resources in the health sector.

The results, from the patients’ perspective, to the dimensions of access (accessibility, accommodation, acceptability, affordability) are compatible with developed countries, with indicators situated between 70% and 90% compliance. However, access to medicines is still heavily compromised by the low availability of essential medicines in public health units, confirming that it does not occur universally, equally, and decisively to the population, and that it remains a challenge to SUS.
