Spanish to English Bus/Financial Medical: Pharmaceuticals Resource Management

Here is the context (such as it is):

***Gestión de bloqueo***: Recuperación mensual de cupos, reduciendo así el bloqueo a un 23,6% en el primer trimestre del presente año, el cual según el bloqueo esperado para este periodo debiese ser del 24,3%.

It is from a text about a management company handling medical centres in South America. It's in a list of the company's activities and there is no further context to help me guess what kind of blocking is being talked about.
