Resumo
The use of forecasting models is becoming even more common in healthcare and administration applications because they can be reliable decision support tools. The live birth rate
is a health index that is directly linked with maternal and newborn health, and its prediction can assist health managers to anticipate resources destined for obstetric and pediatric
services. Thus, the objective of this work is to forecast the number of live births in the
state of Goiás (Brazil) for a 24-month horizon, providing useful information to support
the planning and implementation of public policies. This study investigates two distinct
approaches: univariate and multivariate, allowing a better understanding and management
of the Brazilian territorial hierarchy. Both approaches are evaluated with data provided by
the information system on live births of the information department of the single health
system (SINASC-DATASUS). The dataset is composed of 252 monthly records of the
number of live births for the 18 health regions of Goiás. The results were measured in
prediction ability by Mean Absolute Percentual Error (MAPE) and Mean Absolute Error
(MAE). For the univariate approach using a LMU, the average MAPE and MAE achieved
were 6.4614 and 19.9136, respectively. The multivariate approach was combined with the
K-means method for clustering similar time series using a dynamic time warping measure,
generating an average result of 5.5985 and 18.1360 for MAPE and MAE, respectively.
