Mercy Clinics will discontinue most of its outpatient mental health services for adults in Greater Des Moines effective Aug. 29, The Des Moines Register reportedThe change will require about 8,000 adult patients to receive services from other health care providers, and could result in even longer delays for patients seeking care due to a shortage of mental health services in Iowa. A Mercy administrator said the decision was made because three of Mercy's five psychiatrists with Mercy Behavioral Health Services had recently retired or taken other positions. The announcement affects mental health services for adults who see Mercy psychiatrists, nurse practitioners or mental health therapists for conditions such as depression, schizophrenia or bipolar disorder. The closure doesn't affect Mercy's mental health services for children and adolescents, the addiction treatment or partial hospitalization programs. Mercy may reopen its outpatient mental health clinic if it can recruit new psychiatrists, an official said.
