Abstract

Objective:

to analyze records of hospitalizations due to mental and behavioral disorders before and after the beginning of the covid-19 pandemic in Brazil, from January 2008 to July 2021.

Methods:

this was a descriptive ecological interrupted time series study, using secondary data retrieved from the Brazilian National Health System Hospital Information System; a time series analysis of hospitalizations was conducted based on a population-weighted Poisson regression model; relative risk (RR) and respective 95% confidence intervals (95%CI) were calculated.

Results:

we identified 6,329,088 hospitalizations due to mental and behavioral disorders; hospitalization rates showed an 8% decrease (RR = 0.92; 95%CI 0.91;0.92) after the start of the pandemic, compared to the pre-pandemic period.

Conclusion:

the pandemic changed the trend of hospitalizations due to mental and behavioral disorders in Brazil; the drop observed in the period is evidence that the pandemic affected the mental health care network.

INTRODUCTION

According to the International Health Regulations (IHR), the covid-19 pandemic is an international public health emergency, the highest level of alert issued by the World Health Organization (WHO).11.

Due to its potential for contagion, the characteristics of its evolution and the complexity of its management, covid-19 has posed challenges for health systems in the countries where it has spread.44.

covid-19 mortality has been shown to be higher than that observed for seasonal influenza, and the complications caused by the virus lead to an increase in the demand for care, generating overload for all levels of care, especially tertiary care (hospital, intensive care). This behavior shown by covid-19 triggers public health crises, both in developing countries and in wealthy countries on all continents, creating a situation unprecedented in recent decades.55. Faro A, Bahiano MA, Nakano TC, Reis C, Silva BFP, Vitti LS. COVID-19 e saúde mental: a emergência do cuidado. Estud Psicol. 2020;37:e200074. doi: 10.1590/1982-0275202037e200074

Clinical management of people with a highly contagious severe disease, with a little known clinical picture, and with no available treatment, had repercussions on the regular process of providing care related to the treatment and prevention of other diseases not associated with covid-19, as well as mental health.

Worldwide, the covid-19 pandemic has had impacts on the population’s mental health and psychosocial well-being. Psychological suffering, which affected different segments of the population, has been a consequence of the immediate effects of the virus on people’s health and measures to contain transmission, including social isolation, suspension of services and the resulting economic crisis.88.

Fear, stress, feelings of helplessness, loneliness, insomnia, anger, depression, anxiety, post-traumatic stress, suicide ideations, suicide attempts and/or suicide itself are some of the manifestations reported in the literature.1010.

Notwithstanding, people who had mental disorders before the pandemic are among the groups most vulnerable to the worsening of mental health problems.1212.

Mental health care within the scope of the Brazilian National Health System (Sistema Único de Saúde - SUS) aims to ensure that people with mental suffering or mental disorders and with needs resulting from the use of crack, alcohol and other drugs have access to comprehensive and humanized care.1515. Nóbrega MPSS, Silva GBF, Sena ACR. Funcionamento da Rede de Atenção Psicossocial-­‐RAPS no município de São Paulo, Brasil: perspectivas para o cuidado em Saúde Mental. Investigação Qualitativa em Saude. 2016;2:41-9. The Psychosocial Care Network (Rede de Atenção Psicossocial - RAPS) was structured to meet this purpose. The RAPS brings together different services in a territorialized network, and includes everything from primary health care to hospital care, reinforcing its articulation as a way of guaranteeing the effectiveness of care.1616. Zanardo GLP, Silveira LHC, Rocha CMF, Rocha KB.

https://doi.org/10.1590/1980-54972017000...

The RAPS Hospital Care component offers support in general, pediatric and maternity hospitals, through short-term hospitalizations, to people with mental suffering or disorders, jointly with the Psychosocial Care Centers (Centros de Atenção Psicossocial - CAPS) and other health and social service points of care.1717.

Studies evaluating the secondary effects of covid-19 on mental health are scarce, despite their importance in the current scenario. The population, in general, when exposed to the risk of contamination and the possibility of becoming ill due to covid-19, can experience situations of vulnerability that enhance the development of mental health problems.1414. Pavani FM, Silva AB, Olschowsky A, Wetzel C, Nunes CK, Souza LB. Covid-19 and repercussions in mental health: a narrative review of literature. Rev Gaucha Enferm. 2021;42(spe):e20200188. doi: 10.1590/1983-1447.2021.20200188
https://doi.org/10.1590/1983-1447.2021.2...
This study is part of this context and aimed to analyze the trend of hospitalizations due to mental and behavioral disorders before and after the beginning of the covid-19 pandemic in Brazil.

METHODS

Study design

This was a descriptive ecological interrupted time series study, using secondary data retrieved from the Brazilian National Health System Hospital Information System (Sistema de Informações Hospitalares do Sistema Único de Saúde - SIH/SUS). We analyzed hospitalizations due to mental and behavioral disorders from January 2008 to July 2021.

Setting

According to Demographic Census data, in 2010 Brazil had a population of 190,755,799 inhabitants,1818. Ministério da Saúde (BR). Datasus: população residente Brasil - 2010 [Internet]. Brasília: Ministério da Saúde; 2012 [citado 2022 Nov 12]. Disponível em: Disponível em: http://tabnet.datasus.gov.br/cgi/tabcgi.exe?ibge/cnv/popuf.def
http://tabnet.datasus.gov.br/cgi/tabcgi....
distributed over five geopolitical regions - North, Northeast, Midwest, Southeast and South - each of which have different demographic, economic and social characteristics.

As at December 2020, Brazil had 1,927 beds in Reference Hospital Services for Mental Health, Alcohol and other Drugs. In 2012, these services were regulated and intended to care for clinical comorbidities resulting from the use of psychoactive substances, especially abstinence and severe intoxication, as well as management of mental health crisis situations, together with the CAPS and other RAPS points of care. With regard to beds in psychiatric hospitals, between 2002 and 2020, nationwide the SUS reduced its psychiatry beds by 37,464, in line with the recommendations of the Psychiatric Reform Law (Law No. 10216/2001), intended to reorient the mental health care model in Brazil.1919. Desinstitute. Painel saúde mental: 20 anos da Lei 10.216/01. Brasília: Desinstitute; 2021.

This study examined records of hospitalizations associated with mental and behavioral disorders, as per the International Statistical Classification of Diseases and Related Health Problems - 10th Revision (ICD-10). We conducted a comparative analysis, taking two moments in time: a period prior to the covid-19 pandemic and a period following the onset of the pandemic.

We took January 2008 to February 2020 as the pre-covid-19 pandemic period, and April 2020 to July 2021 as the post-onset period. The intervention measure considered was the WHO declaration of the covid-19 pandemic, in March 2020.

Participants and variables

For the purposes of this study, mental and behavioral disorders were based on the records of hospitalizations of people resident in Brazil, from January 2008 to July 2021, with primary diagnosis classified as follows: mental and behavioral disorders (F00-F99), symptoms and signs involving emotional state (R45) and external causes of morbidity and mortality (X60-X84), as per ICD-10 chapters V, XVIII and XX, respectively. Given that the data were available until July 2021 and not for the whole of 2021, the time series was structured month by month in order to enable comparison.

The following variables were included in the study:

  1. - health service user identification: date of birth, race/skin color (White, Black, mixed race, Asian, Indigenous, unknown and not informed), sex (male, female), region of residence (Midwest, Northeast, North, Southeast, South and not informed);

  2. - main ICD-10 code (F00-F99, R45 and X60-X84);

  3. - nature of hospitalization (elective, urgency, occupational accident, accident on the way to or from work, other types of transport accident, other types of injury and poisoning due to chemical or physical agents);

  4. - hospitalization date;

  5. - number of inpatient days;

  6. - number of charged days;

  7. - total hospitalization cost (in BRL);

  8. - reason for charging (grouped into the following categories: discharge, inpatient stay, transfer, death, administrative case closure and not informed); and

  9. - occurrence of death in the period (no, yes).

  10. Data sources/measuring

Anonymous SIH/SUS databases were used as sources of information. We chose SIH/SUS databases due to the public availability of data on hospitalizations paid for by SUS. The SUS user population corresponds to 75% of the Brazilian population and, due to its scope, the SIH/SUS allows for analysis of changes in trends linked to mental health hospitalizations. The data were extracted in October 2021 from the SUS Department of Information Technology (DATASUS) website, and hospitalizations were aggregated by region of residence of people with mental suffering or disorder and year of hospitalization.

The third digit of the ICD-10 code of the primary diagnostic field was excluded, and all subdivisions of groups F00-F99, R45 and X60-X84 were considered. The ages of people with mental and behavioral disorders were calculated by the difference between the date of hospital admission and date of birth.

Population data from the 2010 Demographic Census and intercensal population projections, made available by the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística - IBGE), were used to estimate hospitalization rates per resident population2020. Ministério da Saúde (BR). Datasus: morbidade hospitalar do SUS (SIH/SUS) [Internet]. Brasília: Ministério da Saúde; 2021 [citado 2021 Jul 22].

multiplied by 10,000 inhabitants, for Brazil as a whole.

Statistical analysis

The continuous variables were described using mean values and standard deviation (SD); while the categorical variables were described using frequencies and percentages.

In order to identify changes in the level and slope of trends in hospitalization rates for the pre-pandemic and post-pandemic onset periods, we opted to use interrupted time series analysis.

The time series analysis of mental and behavioral disorder hospitalizations was based on a population-weighted Poisson regression model. Mental and behavioral hospitalizations per year were used to measure the outcome. Changes in the hospitalization rate over to time and due to the pandemic were analyzed. The pandemic variable was added to the model as a dummy. We calculated relative risk (RR) taking a 95% confidence interval (95%CI) and taking models with a p-value < 0.05 to be statistically significant.

Number of hospitalizations ~ log (population) + pandemic + time + weighted harmonics

The selection of this model was based on estimated count data - in this case, the number of hospitalizations. Thus, the count data was modeled directly, using the population (transformed log) as a compensation variable. Residual autocorrelation parameters were used to validate the results. The choice of the method shown above was based on the recommendations made by Bernal et al. (2017).2121. Bernal JL, Cummins S, Gasparrini A. Interrupted time series regression for the evaluation of public health interventions: a tutorial. Int J Epidemiol. 2017;46(1):348-55. doi: 10.1093/ije/dyw098
https://doi.org/10.1093/ije/dyw098...

The analyses were performed using the R statistical language, both for data analysis and for graph production, with the support of the lmtest, EPI and tsModel packages.

We used anonymous secondary public database information. As such, the study was exempted from submission to a Research Ethics Committee.

RESULTS

We analyzed 6,329,088 records of hospitalizations due to mental and behavioral disorders. The region of the country with the highest number of hospitalizations was the Southeast (3,130,919; 49.0%), while the Northern region had the lowest number (113,254; 1.8%) (Table 1).

Table 1
Distribution of mental and behavioral disorder hospitalizations by year and geographic region, Brazil, January 2008 to July 2021

Males accounted for 64.0% of hospitalizations; 30.6% were of White race/skin color, and 20.3% were of mixed race. Mean age was 42 years (SD = 15). The majority of hospitalizations were urgent (53.6%) and lasted, on average, 20 days (SD = 12), corresponding to 19 days - length of hospital stay used to calculate the amount to be paid by the SUS. The annual mean cost of hospitalization ​​was R$ 927 million (SD = 614). Of the total records, 48.2% of service users were discharged, 47.5% remained hospitalized and 2.6% were transferred to another establishment. Death accounted for 0.3% of hospitalizations. Primary diagnosis indicates that schizophrenia, schizotypal and delusional disorders accounted for 43.0% of hospitalizations, followed by mood (affective) disorders and mental and behavioral disorders due to alcohol use (14.0% each). Mental and behavioral disorders due to use of other psychoactive substances accounted for 13.0% of hospitalizations (Table 2).

Figure 1 A shows the trend in hospitalization rates for mental and behavioral disorders per 10,000 inhabitants. The breakdown of the time series trend revealed a decrease (Figure 1B). As such, there was a downward trend in hospitalizations due to mental and behavioral disorders with effect from 2008 and throughout the pre-pandemic period, ranging from 27.3 to 12.8, with a certain stability between 2017 and 2020.

Table 3 presents a summary of the analyses of hospitalizations before and after the start of the covid-19 pandemic in Brazil, from January 2008 to July 2021. We analyzed 148 months in the period before the pandemic and the WHO intervention, as well as 16 months in the period after the onset of the pandemic.

Table 3
Characterization of hospitalizations before and after the onset of the COVID-19 pandemic, Brazil, January 2008 to July 2021

Our analysis of the means and SD for the periods showed that there was a decrease in hospitalizations. In the pre-pandemic period, the mean number of hospitalizations was 39,487.6 (SD = 8,364.2), while after the onset of the pandemic, the mean number of hospitalizations fell to 24,059.2 (SD = 1,500.2). The interquartile range revealed lower data dispersion in the post-pandemic period.

Poisson regression analysis showed a statistically significant reduction in hospitalization rates in the period after the start of the pandemic, RR = 0.92 (95%CI 0.91;0.92), that is, an 8% decrease in hospitalizations due to mental and behavioral disorders associated with the pandemic period compared to the pre-pandemic period (Table 4). This result was statistically significant (p-value < 0.001), even when controlled for seasonality and stationarity effects.

DISCUSSION

The results presented demonstrate a decrease in hospitalization rates due to mental and behavioral disorders in Brazil with effect from the onset of the covid-19 pandemic, and indicate that this decrease became more pronounced in the pandemic period covered by this study. This downward trend had become more visible since 2014, which may be related to the implementation of RAPS in the years prior to this.2222. 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).

https://pesquisa.in.gov.br/imprensa/jsp/...

The inclusion of Specialized Psychiatric Hospitals as part of the RAPS, and respective alteration of the Hospital Admission Authorization (Autorização de Internação Hospitalar - AIH), as well as the incorporation of Specialized Reference Units in General Hospitals, which must have 80.0% of these beds occupied, can be considered elements that led to the stability of the drop in hospitalizations in the period from 2017 to the pre-pandemic in 2020. This may imply a change in the logic of hospitalization for mental health problems, reversing efforts made during more than ten years intended to deinstitutionalize health service users with mental and behavioral disorders.

The reduction in hospitalization rates found by the study for the pandemic period is in line with a recent report published by the WHO which highlighted that essential mental health services were interrupted in 93.0% of countries around the world during the period of social isolation,2323. World Health Organization. The impact of COVID-19 on mental, neuro- logical and substance use services: results of a rapid assessment [Internet]. Geneva: World Health Organization; 2020 [cited 2021 Dez 15]. 36 p. Available from: Available from: https://apps.who.int/iris/bitstream/handle/10665/335838/9789240012455-eng.pdf
https://apps.who.int/iris/bitstream/hand...
which may have led to a significant decrease in hospitalizations. On the other hand, in Brazil, studies indicate that, due to the high demand for intensive care beds (ICU) for people diagnosed with covid-19, some beds intended for service users with mental disorders, and even psychiatric hospitals, were transformed into covid-19 wards and intensive care beds.2424.

https://doi.org/10.25248/reas.e8340.2021...
The sharp drop observed in the period is evidence that the pandemic has affected the mental health care network. The findings of the study point to a significant reduction in the volume of hospitalizations.

In keeping with the most frequent results of studies conducted in Brazil,1616. Zanardo GLP, Silveira LHC, Rocha CMF, Rocha KB.

The mean hospital stay of 20 days can be interpreted positively, and may be associated with the community care model being prioritized to the detriment of the hospital-centered model, in keeping with the perspective advocated by the Psychiatric Reform.

Regarding hospitalizations according to ICD-10 subgroup, we found that the highest frequency of hospitalizations occurred due to schizotypal and delusional disorders, followed by mood (affective) disorders, mental and behavioral disorders due to alcohol use and mental and behavioral disorders due to use of other psychoactive substances, corroborating findings of studies conducted in Brazilian states.2525.

A report published in 2018 by the Pan American Health Organization (PAHO/WHO) on the burden of mental disorders in the Americas region, shows Brazil as having the highest percentage of disability due to mental disorders (36.5%). Depressive disorders and anxiety disorders accounted for 9.3% and 7.5%, respectively. Schizophrenia, considered to be a serious mental disorder, accounted for 1.6% compared to the other countries of the region.2929. Pan American Health Organization.

Studies indicate that the covid-19 pandemic caused significant changes in hospitalizations due to various causes, and this is one of the pioneering studies that analyzed data from Brazil, using quasi-experimental methods. Although access to health services has been affected in several medical specialties, it is important to consider that mental health is a historically neglected area and that the number of health services is insufficient. Evidence shows that there is a delay between the appearance of the first symptoms of a mental disorder and seeking specialist care, which means that we are likely to see the consequences for mental health in the coming years.1010. Ornell F, Schuch JB, Sordi AO, Kessler FHP. “Pandemic fear” and COVID-19: mental health burden and strategies. Braz J Psychiatr. 2020;42(3):232-5. doi: 10.1590/1516-4446-2020-0008
https://doi.org/10.1590/1516-4446-2020-0...
The findings indicate that the pandemic significantly reduced mental health hospitalizations, and additional studies are needed to better understand the consequences of this finding. Additionally, it is known that the pandemic did not uniformly affect the different Brazilian states. As such, complementary studies are essential to understand local specificities.

Standing out among the limitations of this study is the change in the National Mental Health Policy during the period analyzed, which can lead to the misinterpretation that the pandemic has modified the pattern of hospitalizations, resulting in a decrease, whereas this effect may have resulted from the change in the logic of mental health care in favor of deinstitutionalization (dehospitalization), avoiding unnecessary or inappropriate hospitalizations, focusing instead on community-based treatment. However, the findings of this study are initial, and future studies should be developed in order to gain a better understanding of the phenomenon. In addition, analysis by region and/or state, to assess whether these trends are general or different across states, may be an important contribution to the topic.
