ABSTRACT
Abstract This ecological study assessed the impact of the COVID-19 pandemic on completed treatments (CTs) and referrals during urgent dental visits to primary health care units in Brazil, and their associations with socioeconomic, geodemographic, and pandemic index factors in Brazilian municipalities. The difference in rates of procedures 12 months before and during the pandemic was calculated. Data were extracted at baseline from health information systems of all municipalities that provided urgent dental care (n = 5,229 out of 5,570). Multiple logistic regression predicted the factors associated with referrals and CTs. The number of dental urgencies increased from 3,987.9 to 4,272.4 per 100,000 inhabitants. The rates of referrals decreased in 44.1% of the municipalities, while 53.9% had lower rates of CTs. Municipalities with a greater number of oral health teams in the primary health care system (OR = 1.52, 95%CI:1.21-1.91) and with specialized services (OR = 1.80, 95%CI:1.50-2.16) were more likely to decrease referrals during the pandemic. Higher HDI and GDP per capita were associated with a larger decrease in referrals and smaller decrease in CTs. The calamity generated by the long pandemic period resulted in a greater demand for urgent visits. Less developed and larger cities seem to have been more likely to not complete treatments during urgent visits in primary dental care units in times of calamity. Primary dental care offices in smaller and less developed municipalities should be better equipped to provide appropriate assistance and to improve the problem-solving capacity of dental services during emergencies.
ABSTRACT
This ecological study described the effect of the COVID-19 pandemic and socioeconomic development on the use and profile of urgent dental care (UDC). UDC rates per 100,000 inhabitants before (from March to June 2019) and during (from March to June 2020) the COVID-19 pandemic in 4,062 Brazilian municipalities were compared. Data were collected from official sources. COVID-19 mortality and hospitalization rates were indicative of levels of lockdown and Human Development Index (HDI) indicated socioeconomic development. Multiple logistic regression and relative excess risk due to interaction (RERI) were used for statistical analyses. The Student t-test was used to compare changes in the profile of UDC causes and procedures in the two periods. Lower UDC rates were found in 69.1% of municipalities and were associated with higher HDI (OR = 1.20; 95%CI: 1.01; 1.42). Mortality had OR = 0.88 (95%CI: 0.73; 1.06) for municipalities with HDI < 0.70 and OR = 1.45 (95%CI: 1.07; 1.97) for municipalities with HDI > 0.70. RERI between HDI and COVID-19 was 0.13 (p < 0.05). Municipalities with greater primary health care coverage had a smaller reduction in emergency rates. Endodontic treatment and dental pain were the most frequent factors both before and during the pandemic. The percentage of UDCs due to pain and soft tissue damage, as well as temporary sealing and surgical procedures, increased. Socioeconomic variables affected UDC rates during the most restrictive period of the COVID-19 pandemic and should be considered in the planning of health actions in future emergencies.
Este estudo ecológico descreveu como a pandemia da COVID-19 e o desenvolvimento socioeconômico afetaram o uso da assistência odontológica de urgência (AOU) e seu perfil. Comparamos taxas de AOU para cada 100 mil habitantes antes (de março a junho de 2019) e durante (de março a junho de 2020) a pandemia da COVID-19 em 4.062 municípios brasileiros. Os dados foram coletados de fontes oficiais. As taxas de mortalidade e internação pela COVID-19 indicaram níveis restritivos de lockdown e Índices de Desenvolvimento Humano (IDH) indicou o nível de desenvolvimento socioeconômico. Foram utilizadas regressões logísticas múltiplas e risco relativo de excesso devido à interação (RERI) para análises estatísticas. O teste t de Student foi usado para comparar alterações no perfil das causas e procedimentos da AOU nos dois períodos. As taxas de AOU foram menores em 69,1% dos municípios e associadas a IDH maior (OR = 1,20; IC95%: 1,01; 1,42). A mortalidade apresentou uma razão de chances de 0,88 (IC95%: 0,73; 1,06) para municípios com IDH < 0,70 e de 1,45 (IC95%: 1,07; 1,97) para municípios com IDH > 0,70. O RERI entre IDH e COVID-19 foi de 0,13 (p < 0,05). Os municípios com maior cobertura de atenção primária à saúde apresentaram menor redução nas suas taxas de emergência. Procedimentos endodônticos e dor dentária foram os fatores mais frequentes antes e durante a pandemia. O percentual de AOUs aumentou devido à dor, danos nos tecidos moles, vedação temporária e procedimentos cirúrgicos. Variáveis socioeconômicas afetaram as taxas de AOU durante o período mais restritivo da pandemia da COVID-19 e devem ser incluídas no planejamento de ações de saúde em emergências futuras.

Se compararon las tasas de AOU por cada 100.000 habitantes antes de la pandemia de COVID-19 (de marzo a junio de 2019) y durante la pandemia de COVID-19 (de marzo a junio de 2020) en 4.062 municipios brasileños. Los datos se recogieron de fuentes oficiales. Las tasas de mortalidad y hospitalización de COVID-19 fueron indicativas de niveles restrictivos de desarrollo socioeconómico e Índice de Desarrollo Humano (IDH). Para los análisis estadísticos se utilizó la regresión logística múltiple y el exceso de riesgo relativo (ERR) debido a la interacción. Se utilizó la prueba t de Student para comparar los cambios en el perfil de las causas y los procedimientos de AOU en los dos períodos. Las tasas de AOU fueron menores en el 69,1% de los municipios y se asociaron con un IDH más alto (OR = 1,20; IC95%: 1,01; 1,42). La mortalidad tuvo una OR de 0,88 (IC95%: 0,73; 1,06) para los municipios con IDH < 0,70 y de 1,45 (IC95%: 1,07; 1,97) para los municipios con IDH > 0,70. El ERR entre el IDH y el COVID-19 fue de 0,13 (p < 0,05). Los municipios con mayor cobertura de atención primaria tuvieron una menor reducción de las tasas de urgencia. Los procedimientos de endodoncia y la causa del dolor dental fueron los factores más frecuentes tanto antes como durante la pandemia. Aumentó el porcentaje de AOU por dolor y daños en los tejidos blandos, así como el sellado temporal y los procedimientos quirúrgicos. Las variables socioeconómicas afectaron a las tasas de AOU durante el periodo más restrictivo de la pandemia de COVID-19 y deberían incluirse en la planificación de las acciones sanitarias en futuras emergencias.
