Background & Objectives: Delivery and care of mothers is one of the most important services at health systems which efforts to women's health as one of the health priorities.so this study aimed to forecast number of delivery and the use of all facilities for better services to patients was conducted.
Methods: The data used in this study was the number of deliveries per month in Hakim Jorjani hospital in Gorgan during the years 2010 to 2016.Due to the over-dispersion in the data and non-compliance of a Poisson distribution and also serial correlation between the observations, Poisson hidden Markov model was used to predict the frequency of monthly deliveries. Estimating model parameters with maximum likelihood method and Expectation Maximization algorithm is done.
Results: The performed models and their Comparisons using Akaike's information criterion revealed the frequency of delivery in different months in the hospital follow from a Poisson hidden Markov models with three hidden states, the mean Poisson distribution in each component is 193.74, 236.05 and 272.61 labor, respectively.
Conclusion : The results of this study showed that government’s encouraging policies has had short-term and limited results on increasing fertility and that has little effect on the results of the two-year forecast.
