Denver-based hospital system Centura Health will continue operating Ask-A-Nurse, its free call-in nurse service. In early July, Centura said it would close the service due to financial pressures. But Arlen Reynolds, Centura Health chief operating officer, said Centura was deluged with calls and e-mails from the community voicing disappointment about the move. Leaders met to reconsider the issue and decided to continue the service.
