Alarming data on the part of health care providers on the increase of the claim rate and its potential risk has emerged. It is a descriptive study, with the objective of understanding the changes in the healthcare provider sector in recent years, using the temporal analysis of historical series related to the sector. The variables selected for this study were the claim rate, the coverage rate, and the number of private healthcare providers in activity, observed from 2003 to 2014. The method used for evaluation of the temporal trend was Linear Regression. The claim rate and the coverage rate show an upward trend in the period, while the number of operators in Brazil showed a decreasing trend during the same period. These results show that even with the increase in demand, there was a decrease in the number of operators active in the country. The claim rate is one of the possible causes observed this inverse relationship because the increased offers risks of survival and the opening of new operators. Moreover, the decrease in the number of providers, is leading the country to an oligopolistic industry with an increasing demand in the number of beneficiaries. This decrease is also associated with regulatory processes, which regulates the sector's relationship with the beneficiary.
医疗服务提供者提供了有关索赔率上升及其潜在风险的警示性数据。这是一项描述性研究，旨在通过对该行业历史序列的时间分析，了解近年来医疗服务提供者部门的变化。本研究选取的变量为2003年至2014年期间观察到的索赔率、覆盖率以及活跃的私立医疗服务提供者数量。用于评估时间趋势的方法是线性回归。在此期间，索赔率和覆盖率呈上升趋势，而巴西的运营者数量则呈下降趋势。这些结果表明，即使需求增加，该国活跃的运营者数量却有所减少。索赔率是观察到这种反比关系的可能原因之一，因为服务增加带来了生存风险以及新运营者的开业。此外，提供者数量的减少正使该国走向寡头垄断行业，受益人的数量需求不断增加。这种减少还与监管程序有关，监管程序规范了该部门与受益人的关系。
