Abstract

OBJECTIVE:

to describe characteristics of the Mortality Information System (SIM) in municipalities of São Paulo State, in 2015.

METHODS:

descriptive study with data collected through an electronic questionnaire, with questions on the profile of technical managers, human resources and IT structure.

RESULTS:

584/645 municipalities (90.5%) participated; technical managers were mainly women (81.5%), nurses (64.9%), career civil servants (66.1%) and had more than 3 years of work experience with SIM (68.2%); in small-sized municipalities (≤30,000 inhabitants), managers were younger (average age of 37.7 years), were also responsible for other systems (92.4%) and used computers with older operating systems (69.5%); in large-sized municipalities (>200,000 inhabitants), managers were older (average age of 47.1 years) and had higher education level (86.5% with higher education degree), they had fast-access internet (83.8%) and in-house technical support (81.1%).

CONCLUSION:

the technical managers’ profile and availability of technological resources used at SIM were different according to population size of the municipalities.

Introduction

Decision making in Public Health depends on the timely availability of reliable data.¹1. Lima CRA, Schramm JMA, Coeli CM. Gerenciamento da qualidade da informação: uma abordagem para o setor saúde. Cad Saúde Colet. 2010 jan-mar;18(1):19-31. The role of health information systems (HIS) is to produce, analyze and publicize such data, which makes them important tools for heath situation diagnosis, generating knowledge to support health services management and to plan interventions regarding the health needs of the population, in all levels of the Brazilian National Health System (SUS).¹1. Lima CRA, Schramm JMA, Coeli CM. Gerenciamento da qualidade da informação: uma abordagem para o setor saúde. Cad Saúde Colet. 2010 jan-mar;18(1):19-31.^,22. Almeida MF, Alencar GP. Informações em saúde: necessidade de introdução de mecanismos de gerenciamento dos sistemas. Inf Epidemiol SUS. 2000 out-dez; 9(4):241-9.

The decentralization of SUS health services led to the need to organize municipal information systems. Currently, the municipalities are co-responsible for monitoring, assessing and releasing information on health situation, organizing and coordinating HIS, using epidemiology to set priorities, allocate resources and refer programmatic guidelines on the local health.³3.

Diário Oficial da República Federativa do Brasil, Brasília (DF), 1990 set 20; Seção 1:18055. For some authors, HIS decentralization increased without a cautious process of responsibilities transference from the national level to state and municipal levels.²2. Almeida MF, Alencar GP.

Sistemas de informação em saúde no nível local. Cad. Saúde Pública 1996 abr-jun;12(2):267-70. The municipalization faced difficulties, partly due to the federalism model, in which municipalities are federated units with political, administrative and financial autonomy, and well established constitutional competencies, however they have huge differences in size, population and socioeconomic aspects⁶6. Branco MAF. Sistemas de informação em saúde no nível local. Cad. Saúde Pública 1996 abr-jun;12(2):267-70.^,77. Silva ZP, Barreto Junior IF, Sant'ana MC. Saúde do trabalhador no âmbito municipal.

Estratificação de municípios brasileiros para avaliação de desempenho em saúde. Epidemiol Serv Saúde. 2016 out-dez;25(4):767-76. all these factors should be considered in the analyses of HIS decentralization.

Since 1975, in order to understand the epidemiological profile of mortality in the country, Brazil uses the Mortality Information System (SIM), originally centralized by the Ministry of Health.⁹9.

With the advance of the decentralization process, the municipalities became responsible not only for data collection, but also for management and assessment of HIS. From 2005 to 2010, São Paulo State, following national guidelines,¹¹11. Brasil. Ministério da Saúde. Portaria nº 116, de 11 de fevereiro de 2009.

Although SIM coverage has increased, especially with the experience of active search for vital events,¹⁴14. Cunha CC, Campos D, França EB. Uso da busca ativa de óbitos na avaliação do sistema de informações sobre mortalidade em Minas Gerais, Brasil. Epidemiol Serv Saúde. 2011 jul-set;20(3):275-86. there are still some quality problems regarding the causes of death and fetal deaths.⁹9. Mello Jorge MHP, Laurenti R, Gotlieb SLD. Análise da qualidade das estatísticas vitais brasileiras: a experiência de implantação do SIM e do Sinasc. Ciên Saúde Coletiva. 2007 maio-jun;12(3):643-54. In Brazil, there have been some recent researches on operationalization and management of HIS in municipal level,⁵5. Vidor AC, Fischer PD, Bordin R. Utilização dos sistemas de informações em saúde em municípios gaúchos de pequeno porte. Rev Saúde Pública. 2011 fev;45(1):24-30.^,1717. Guimarães EAA, Filho Loyola AI, Hartz ZMA, Meira AJ, Luz ZMP.

Understanding the conditions in which the data are generated can help subsidize the three government levels in the improvement of quality and management of SIM. This study aimed to describe the characteristics of the Mortality Information System (SIM) in municipalities of São Paulo State, in 2015.

Methods

This is a descriptive study, conducted in São Paulo State. The state has a population of 41,223,683 inhabitants, distributed in 645 municipalities, of which 90% presented high/very high HDI in 2010.¹⁹19. Fundação Sistema Estadual de Análise de Dados. Informações dos municípios paulistas [Internet]. São Paulo; 2016 [citado 2017 mar 29]. Disponível em: Disponível em: http://www.imp.seade.gov.br/frontend/#/tabelas .
http://www.imp.seade.gov.br/frontend/#/t...

An electronic questionnaire via FormSUS (formsus.datasus.gov.br/) was applied between March and May 2015. The questionnaire was sent to all Municipal Health Departments of the state (n=645); it was elaborated based on the minimal requirements of the working processes established by the Ministry of Health,¹¹11. Brasil. Ministério da Saúde. Portaria nº 116, de 11 de fevereiro de 2009. Regulamenta a coleta de dados, fluxo e periodicidade de envio das informações sobre óbitos e nascidos vivos para o Sistema de Informações em Saúde. Diário Oficial da República Federativa do Brasil, Brasília (DF), 2009 fev 12; Seção 1:29. and in other requirements found in the literature.⁵5. Vidor AC, Fischer PD, Bordin R. Utilização dos sistemas de informações em saúde em municípios gaúchos de pequeno porte. Rev Saúde Pública. 2011 fev;45(1):24-30.^,1717. Guimarães EAA, Filho Loyola AI, Hartz ZMA, Meira AJ, Luz ZMP. Avaliação da Implantação do sistema de informação sobre nascidos vivos em municípios de Minas Gerais. Cad Saúde Pública. 2013 out;29(10):2105-18. The questionnaire was pre-evaluated by two specialists. The municipal managers received an invitation containing instructions on how to fill in the questionnaire and a recommendation for the instrument to be answered by the manager responsible for SIM. The Center for Diseases Control of the State Health Department (CDC/SES) disclosed the research.

The dimensions and variables studied were:

The municipalities were grouped according to population size, based on 2014 estimates by the Brazilian Institute of Geography and Statistics (IBGE), stratified into three groups: up to 30,000 inhabitants (small-sized); from 30,001 to 200,000 inhabitants (medium-sized); and above 200,000 inhabitants (large-sized). The choice considered the clipping of municipalities <30,000 inhabitants, used by the Ministry of Health to monitor regularity of data supply at SIM and to maintain the transfer of resources of the component Surveillance and Health Promotion.¹²12. Brasil. Ministério da Saúde. Portaria nº 201, de 3 de novembro de 2010. Regulamenta as atividades da vigilância epidemiológica com relação à coleta, fluxo e a periodicidade de envio de dados da notificação de mortalidade e doenças de notificação compulsória. Diário Oficial da República Federativa do Brasil, Brasília (DF), 2010 nov 04; Seção 1:88. We also used the average number of deaths obtained per from the municipalities where the death occurred and the range of values, according to population size of municipalities, provided by CDC/SES.

We conducted descriptive statistics analyses and elaborated distribution and central tendency measurements. Pearson chi-square, Fisher exact test and ANOVA were used in the comparison of proportions and averages, between the three groups of municipalities. A 5% significance level was adopted. Data were processed using Statistical Package for the Social Sciences (SPSS) version 17.0.

This study is tied to the research ‘Decentralization of the Health Information Systems in municipalities of São Paulo State’. The project was approved by the Ethics in Research Committee of the School of Public Health of the University of São Paulo: Report No. 766,167, dated August 26^th 2014.

Results

A total of 584 municipalities (90.5%) answered the questionnaire, which represents a loss of 61 municipalities (9.5%), distributed as follows, according to population size: 9.0% (40/446), 11.3% (18/159) and 7.5% (3/40), among small, medium and large-sized municipalities, respectively.

Table 1 shows that the annual average volume of deaths grew as the population size increased. Of the 584 participant municipalities, about 70% were small-sized and only 6% were large-sized. As expected, there was great range in the occurrence of deaths: whilst in smaller municipalities the annual average was about 40 deaths, in large-sized municipalities (excluding the municipality of São Paulo), this number was close to 2,850, ranging from 690 to 8,777.

SIM was predominantly allocated at the Epidemiological Surveillance sector, followed by the health care unit; only 12.0% were in the health information sector of the Health Department. The Epidemiological Surveillance was more frequent in medium (86.5%) and large (78.4%) municipalities; in small-sized, the allocation in health care unit (40.1%) or in the Epidemiological Surveillance (40.6%) presented similar proportions. The differences between the municipalities groups were statistically relevant (p<0.001).

With regard to the profile of technical managers, most of them were women (81.5%) in all the groups, with no statistically significant differences (p=0.167). Age ranged from 20 to 67 - average of 39.3 years old (95%CI 29.5;49.1) -, with an increase from small-sized municipalities (37.7; 95%CI 28.6;46.8) to larger municipalities (47.1; 95%CI 35.3;58.8). In small municipalities, 63.5% of the managers were less than 40 years old, a higher proportion when compared to medium-sized (48.2%) and large-sized municipalities (27.0%) (p<0.001) (Table 2).

Most managers had higher education degree (78.9%), which was most common in larger municipalities (p=0.017). Among the 21.1% who did not have higher education degree, the amount of individuals with only Elementary School degree was small (1.7%). For the municipalities where the technical manager of SIM had higher education degree, we obtained data on the academic degree of 73.5% of them, with prevalence of Health Sciences (76.5%), followed by Applied Social Sciences (14.0%). A total of 38 academic degrees were mentioned, with lower variety (n=9) in larger municipalities; the most common was Nursing (64.9%), followed by Administration (4.1%) and Medicine (3.2%). More than 70.0% of the managers in small municipalities were nurses; in medium and large municipalities, this proportion dropped to 54.8% and 41.7%, being followed by physicians, with 6.0% and 20.8%, respectively.

With regard to employment relationship, the most common was career civil servant (66.1%), with a proportion of 81.1% in large municipalities. CLT employees were the second most common (24.0%) - it dropped as the population size increased; 7.9% occupied commissioned position, with no relevant differences between the groups of population size (p=0.086) (Table 3).

With regard to length of time working in the Health area, most professionals had been working for 3 years or more in the area (88.9%), reaching 97.3% in large-sized municipalities, with no relevant differences between the groups of municipalities (p=0.091). Most municipalities had experienced professionals working with SIM management: 68.2% had 3 or more years of experience, with no relevant differences between the groups (p=0.332), although about 10.0% were responsible for the system for less than a year.

The State Health Department of São Paulo informed that in almost all municipalities the technical manager of SIM was also responsible for the Information System on Live Births (Sinasc). Only three municipalities had different managers for each system. Overload of responsibilities was high (83.7%), and more frequent in small municipalities (92.4%) than in larger (32.4%) (p<0.001): in small municipalities, 86.0% of the managers were responsible for up to five HIS, besides SIM and Sinasc. The other systems most mentioned were: Information System for Notifiable Diseases (Sinan) (80.0%) and Brazilian National Immunization Program Information System (SI-PNI) (63.2%); in a smaller frequency, the following systems were mentioned: Monitoring System of the Humanization Program in Prenatal Care and Birth (SisPreNatal) (37.0%), Primary Health Care Information System (SIAB) and SUS Ambulatory Care Information System (SIA/SUS) (19.4%).

A total of 1,237 professionals were working with SIM on December 31^st 2014 - average of 2.12 (95%CI 1.02;3.22) per municipality -, 61.4% of them were in small-sized municipalities, 27.1% in medium-sized, and 11.5% in large-sized. About half of small and medium municipalities had two employees at SIM staff, and 48.6% of large municipalities had 4 or more, representing significant differences (p<0.001) (Table 4).

With regard to upgrading of technology infrastructure, 68.3% used Windows XP as operating system to load SIM, 20.0% used Windows 7 and only 2.4% used Windows 8, this latter being the most recent at the time; 50 respondents did not know the type of operating system used (Table 4).

Data were exported to higher management levels monthly. Among the municipalities, 74.3% had fast-access internet. 20.7% had radio access internet and 2.9% had dialed internet, this latter being restricted to small and medium municipalities; 2.1% informed not having internet access in the computers used to load SIM (p=0.432). It was verified that 93.7% had computing technical support; 61.8% had in-house service, more than 80.0% of those were in medium and large municipalities; 31.8% of municipalities counted with outsourced service (p<0.001).

Discussion

São Paulo State municipalities have differences in the management of SIM, depending on the municipality population size. In smaller municipalities, technical managers were younger, were also responsible for other information systems, used computers with older operating systems and relied more on outsourced technical support. In larger municipalities, managers were older, had higher education level, there was a prevalence of career civil servants, with more experience with SIM and less responsibility with other systems; those municipalities had more computers, updated operating systems, fast-access internet and exclusive technical support.

São Paulo State is the Brazilian federative unit with the largest population in the country, and, consequently, has the highest volume of events recorded at SIM - the municipalities studied answer for the record of more than 277 thousand deaths -, and its coverage is considered of good quality.¹⁵15. Frias PG, Szwarcwald CL, Lira PIC. Avaliação dos sistemas de informações sobre nascidos vivos e óbitos no Brasil na década de 2000. Cad Saúde Pública. 2014 out; 30(10):2068-280. We verified a variation in the average number of deaths according to population size, which may explain the differences found in human resources, equipment and technical support regarding SIM. It is worth mentioning that the great participation of small-sized municipalities, although they have little events occurrence, not only can be seen in São Paulo State, but it is similar throughout the country.

SIM has been managed by several areas of the Ministry of Health over its history, and in 2003 the Secretariat of Health Surveillance (SVS) took over the management of the system in the national level.¹⁰10. Mello Jorge MHP, Laurenti R, Gotlieb SLD. O sistema de informações sobre mortalidade - SIM: concepção, implantação e avaliação. In: Ministério da Saúde. Organização Pan-Americana da Saúde.

http://bvsms.saude.gov.br/bvs/publicacoe... In local level, we observed that in medium and large-sized municipalities of São Paulo State, SIM was mostly allocated in the Epidemiological Surveillance, a fact related to some functions of this area, such as surveillance of death and of notifiable diseases; the transfer of resources of the component Surveillance and Health Promotion is linked to SIM fulfillment and immediate report of maternal and infant death.²⁰20. Brasil. Ministério da Saúde. Portaria nº 1.271, de 7 de junho de 2014. Define a lista nacional de notificação compulsória de doenças, agravos e eventos de saúde pública nos serviços de saúde públicos e privados em todo o território nacional, nos termos do anexo, e dá outras providências. Diário Oficial da República Federativa do Brasil, Brasília (DF), 2014 jun 09; Seção 1:67. In small-sized municipalities, the allocation in primary health care units may be related to the small structure of local Health. In large-sized municipalities, the allocation of SIM in information sectors of the Municipal Health Departments aims at optimizing the data processing related to all their activities - including health care data -, which may demand a specific structure to handle the processing of big amounts of data.

In each municipality there is a technical manager responsible for managing the system at local level and establish the communication with the health care facilities and regional and state levels. We identified a prevalence of women in this function, which is similar to a study that assessed the profile of the manager in health care units of Belo Horizonte, Minas Gerais, between 2000 and 2001.²¹21. Alves M, Penna CMM, Brito MJM. Perfil dos gerentes de unidades básicas de saúde. Rev Bras Enferm. 2004 ago;57(4):441-6. These data expressively reflect the feminization of health work, a fact identified some decades ago.²²22. Machado MH, Wermelinger M, Tavares MFL, Moysés NMN, Teixeira M, Oliveira ES.

http://www.observarh.org.br/observarh/re...

A little more than half of the managers were less than 40 years old, proportion lower than in a study about the responsible for Sinasc (66.0%) in municipalities from Minas Gerais State, in 2010.¹⁷17. Guimarães EAA, Filho Loyola AI, Hartz ZMA, Meira AJ, Luz ZMP. Avaliação da Implantação do sistema de informação sobre nascidos vivos em municípios de Minas Gerais. Cad Saúde Pública. 2013 out;29(10):2105-18. The responsible for SIM are younger in smaller municipalities, whilst in larger municipalities there is a high number of workers above 50 years. This may be related to a solid administrative structure, which enables the professional to work longer in that function.

SIM managers present high education level, which was less frequent in small municipalities. São Paulo State Health Department, considering the importance of SIM and the need of knowledge about legal matters, established that the system’s technical manager should have higher education degree (Resolution No. 66, dated May 3^rd 2010).²³23. São Paulo. Secretaria da Saúde do Estado de São Paulo. Resolução nº 66, de 3 de maio de 2010. Disciplina o cadastro e acesso de responsáveis técnicos e usuários às bases de dados dos sistemas de informações de mortalidade - SIM - e sobre nascidos vivos - Sinasc -, no âmbito do Estado de São Paulo, e dá outras providências. Diário Oficial do Estado de São Paulo. São Paulo (SP), 2010 maio 04; Seção 1:29. This Resolution may have contributed to the high proportion of managers with higher education degree. In turn, as 21.1% of the municipalities did not fulfill this requirement, it may suggest unavailability of more qualified professionals. Indeed, the literature points to higher deficiency and staff turnover in smaller municipalities.⁵5. Vidor AC, Fischer PD, Bordin R.

Most SIM managers are career civil servants, especially those from larger municipalities, which may suggest low staff turnover; in smaller municipalities, there was higher participation of CLT employees, probably because this type of hiring process is faster and more flexible. These results are similar to those obtained in a research on the staff of municipal direct administration in Brazil, conducted in 2013, in which the Southeast region registers a prevalence of career civil servants, followed by not stable civil servant; this latter reduce as the population size of the municipality increases.²⁵25. Instituto Brasileiro de Geografia e Estatística. Pesquisa de informações básicas municipais: perfil dos municípios brasileiros 2013 [Internet]. Rio de Janeiro: IBGE; 2014 [citado 2017 ago 21]. Disponível em: Disponível em: http://www.ibge.gov.br/home/estatistica/economia/perfilmunic/2013/
http://www.ibge.gov.br/home/estatistica/...

Almost 90% of the managers had been working for at least 3 years in the Health sector, which also indicates the low staff turnover and, consequently, the presence of more experienced professionals. Length of time working with SIM was shorter, probably because the Health workers usually begin with health care activities, and, later, join the activities of the Information area, for which there is no specific career. In 2010, a study on Sinasc pointed that most of the technical managers had been in the function for at least five years.¹⁷17. Guimarães EAA, Filho Loyola AI, Hartz ZMA, Meira AJ, Luz ZMP.

Usually, the quality of information depends on the knowledge of the professionals involved; thus, low staff turnover in an important factor in this sense. Experience enables a better performance in the activities, as shown in a study from Alagoas State, where the workers’ performance was worse as the time in the function was shorter.²⁶26. Mendes TKA, Oliveira SP, Delamarque EV, Seta MH. Reestruturação da gestão das vigilâncias em saúde em Alagoas: a precarização da formação e do trabalho. Trab Educ Saúde. 2016 mai-ago;14(2):421-43.

In small municipalities, workers were also responsible for other information systems. Possibly, this happens because there is a lower demand towards SIM (low occurrence of deaths) and because of the small structure of the Municipal Health Departments. This finding corroborates to a study conducted in Minas Gerais State (2010),¹⁷17. Guimarães EAA, Filho Loyola AI, Hartz ZMA, Meira AJ, Luz ZMP. Avaliação da Implantação do sistema de informação sobre nascidos vivos em municípios de Minas Gerais. Cad Saúde Pública. 2013 out;29(10):2105-18. according to which not only do the professionals take responsibility over more than one information system, but they also accumulate other functions in the Health area.

Most municipalities reported having up to two individuals working with SIM, which is adequate, even in smaller municipalities. The number of events occurred in the municipality determines the size of the team. This was observed in larger municipalities, but there is no defined standard for the size of SIM team. São Paulo state defined that there can be two managers in municipalities with over 500 thousand inhabitants, being mandatory to be one for SIM and one for Sinasc, but it did not signal anything about the team structure.²⁷27. São Paulo. Secretaria da Saúde do Estado de São Paulo. Resolução SS nº 139, de 7 de novembro de 2014. Disciplina o cadastro e acesso de responsáveis técnicos e usuários às bases de dados dos sistemas de informações de mortalidade-SIM e sobre nascidos vivos-Sinasc, no âmbito do Estado de São Paulo e dá outras providencias. Diário Oficial do Estado de São Paulo, São Paulo (SP), 2014 nov 8; seção 1:34. In this present study, we verified an average of 1.87 individuals working with SIM per municipality, which is above the number verified in a 2010 study (1.58);¹³13. Prado MF, Marques CCA. Sistemas de informações em saúde: uma experiência da descentralização da produção das informações sobre mortalidade e nascidos vivos para o uso em vigilância à saúde no estado de São Paulo. BEPA. Bol Epidemiol Paul. 2012 abr;9(100):4-15. this shows the greater involvement of municipal teams with the system.

Technological development contributed to the increase of health data production. At the same time, it brought one more variable to be considered: the update of information technology. Any system demands a minimal structure to achieve its objectives; in the case of SIM, the Ministry of Health has some recommendations related to the operation capacity of the computers that can load the system, the number of devices versus the volume of events, the operating system, internet access and technical support. This survey showed that the number of computers increased as the population size and the number of deaths recorded increased, which is similar to municipalities from Rio Grande do Sul⁵5. Vidor AC, Fischer PD, Bordin R. Utilização dos sistemas de informações em saúde em municípios gaúchos de pequeno porte. Rev Saúde Pública. 2011 fev;45(1):24-30. and Minas Gerais.¹⁷17. Guimarães EAA, Filho Loyola AI, Hartz ZMA, Meira AJ, Luz ZMP. Avaliação da Implantação do sistema de informação sobre nascidos vivos em municípios de Minas Gerais. Cad Saúde Pública. 2013 out;29(10):2105-18. Nowadays, technology evolves very fast; however, in this study only 14 municipalities used an up-to-date operating system. The most obsolete system (Windows XP) found in this study was present in smaller municipalities and suggest that they face financial restrictions concerning the updating of their electronic devices.

Data referral to state and federal levels is periodically monitored, and is related to financial transfers for actions of health surveillance.²⁸28. Brasil. Ministério da Saúde. Portaria nº 47, de 3 de maio de 2016. Define os parâmetros para monitoramento da regularidade na alimentação do sistema de informação de agravos de notificação (Sinan), sistema de informações sobre nascidos vivos (Sinasc) e sistema de informação sobre mortalidade, para fins de manutenção do repasse de recursos do piso fixo de vigilância em saúde (PFVS) e do piso variável de vigilância em saúde (PVVS) do bloco de vigilância em saúde. Diário Oficial da República Federativa do Brasil, Brasília (DF), 2016 maio 05; Seção 1:68. The access to internet in the country is getting increasingly easier. More than two thirds of small-sized São Paulo State municipalities had fast-access internet; however, more than one fifth reported using radio access and a small amount still used dialed access. In a study conducted in 2004, in municipalities from Rio Grande do Sul State with less than 10 thousand inhabitants, 52.0% had dialed internet access and 19.0% had fast-access internet.⁵5. Vidor AC, Fischer PD, Bordin R. Utilização dos sistemas de informações em saúde em municípios gaúchos de pequeno porte. Rev Saúde Pública. 2011 fev;45(1):24-30. Ten years later, São Paulo State municipalities presented higher proportion of fast-access internet, which proves the technological evolution that occurred over the period; however, the radio access followed the same pattern identified in the municipalities from Rio Grande do Sul.⁵5. Vidor AC, Fischer PD, Bordin R. Utilização dos sistemas de informações em saúde em municípios gaúchos de pequeno porte. Rev Saúde Pública. 2011 fev;45(1):24-30. The demand for fast-access internet to send data or for updated versions of systems will become increasingly higher. However, Brazil has an uneven development pattern among its regions, and many municipalities do not even have fast internet services - which is mostly concentrated in larger municipalities -;²⁹29. Macedo HR, Carvalho AXY. Análise de possíveis determinantes da penetração do serviço de acesso à internet em banda larga nos municípios brasileiros. Econ Soc. 2013 ago;22(2):483-520. 77% of Brazilian municipalities have less than 25 thousand inhabitants⁸8. Calvo MCM, Lacerda JT, Colussi CF, Schneider IJC, Rocha TAH. Estratificação de municípios brasileiros para avaliação de desempenho em saúde. Epidemiol Serv Saúde. 2016 out-dez;25(4):767-76. and several are not digitally included,²⁹29. Macedo HR, Carvalho AXY. Análise de possíveis determinantes da penetração do serviço de acesso à internet em banda larga nos municípios brasileiros. Econ Soc. 2013 ago;22(2):483-520. which imposes important challenges for the areas of telecommunication and Health.

As this was a descriptive study, its results reflect the moment when the survey was conducted. Since the questionnaires were self-applied, some words and terms used by researchers may not have been understood by respondents, which would represent a limitation for the research. Among the variables studied, information on the academic degree of the technical manager may present bias, because 26.5% of respondents did not answer this question.

SIM helps calculating important municipal indicators which are settled with the state. The decentralization to municipalities enabled the immediate access to information on mortality and allowed managers to quantify and qualify the distribution of the health problems that affect the population. This can subsidize actions with the aim of improving living conditions and health management models. However, we still have problems in the quality of information with regional differences,¹⁵15.

The knowledge obtained in researches aimed at analyzing HIS implementation may contribute to the identification of problems related to its organizations and functioning, besides supporting decisions directed to its improvement and consolidation.¹1.

The results presented here allow managers to identify different realities of municipal administration, enabling a more directed action planning, capable of covering different types of physical investments, qualification and training for operating and managing the Mortality Information System. They also show the importance of keeping professionals in the area, considering the specifications that the working processes with health information systems demand.
