Análise temporal dos diferenciais de vínculos de trabalho para enfermeiras nas cinco regiões do Brasil entre os anos de 2003-2021

Abstract

The composition of the nursing workforce in Brazil is on average two point forty-eight workers per thousand inhabitants. This design is well below the average of the countries that make up the Organization for Economic Development Cooperation, which has an average composition of nine nurses for every thousand habitants. The objective was to analyze the temporal trend of the nurses' workforce in the regions of Brazil in the period 2003-2021. This is an exploratoryanalytical-descriptive research, with a quantitative approach and with a focus on the ecological study of temporal trends, related to the differences in the employment relationships of nurses in the five regions of Brazil. The database of the Annual List of Social Information was used. The analysis, treatment and temporal distribution were carried out by exporting the database for descriptive and inferential appreciation using Software R Studio version 4.3.1. Statistical analyzes were extracted regarding frequency distribution, measures of central tendencies and positions. Trend analyzes were performed using polynomial equations, which consisted of: simple linear regression, second-degree or parabolic and third-degree or exponential regression. The choice of the model that best fitted the data was considered. The temporal trend analysis was performed in two stages: the Durbin-Watson test to assess the autocorrelation of the historical series and exploratory analysis using the autocorrelation function. The adoption of the significance test was also considered as a criterion for choosing the model, where a significant trend was considered when p-value < 0.05. It was a research that used public domain information, in a database, without the possibility of individual identification. The temporal trend of the differential of employment contracts for nurses was stationary in the Northeast, South, Southeast and Midwest regions, that is, four of the five regions of Brazil. The North Region was the only one that showed an upward trend. Based on the analysis of the time series obtained, this study showed a stable situation in the generation of employment contracts in four of the five regions of Brazil. It is concluded that in Brazil the trend of employment contracts for nurses is predominantly stationary, despite the upward growth in the North of the country.
