The network pulled the second season off the air after just one episode because of low ratings, then aired the second episode 6 months later. Although the show was not officially canceled yet, the actors had already moved on to other projects: Rodolfo Sancho was in La señora (2008); Daniela Costa was in Lalola (2008); and Pau Roca was in Lex (2008)--all three already on the air.
When this series was introduced in an episode of Hospital Central (2000) they both took place in the same hospital. When the series started, it was changed to "Hospital Universitario" but some of the dialogue from the first episodes still referred to it as if it was the same hospital.
Antonio Dávila (Lluís Marco) was a main character of Hospital Central (2000) for several seasons before starring in this series.
