Prevalence of diagnosed depression in mothers of children aged 24 months or less is nearly 20 per cent. (
Reference: Australian Institute of Health and Welfare (2012). Experience of perinatal depression: data from the 2010 Australian National Infant Feeding Survey. Information Paper. Cat. no. PHE 161. Canberra: AIHW
.)
For Western Australia (WA) this would equate to about 6000- 6500 women that gave birth each year.
There are many settings in which women can seek treatment for perinatal depression. These include:
• admissions as inpatients;
• attending at Emergency Departments/services;
• via appointments at Outpatient clinics which are specifically set up to treat perinatal depression;
• via appointments at Outpatient clinics which treat it among a range of other conditions, either related to depression or to birth;
• via appointments at Community Mental Health clinics;
• seeking assistance through telephone health services (e.g. Beyond Blue);
• attending private psychology and/or psychiatry appointments;
• attending GP appointments; and
• visits to child health nurses.
In addition there are some women who may not be treated in one of the formal ways listed above.
In a number of those settings, for example primary care, general practitioner activity data is not available to the Department of Health to quantify the number of treatments.
In other settings, such as child health nursing clinics, accurate counts of treatments provided for perinatal depression are not available in centralised state-wide data collections.
The only available data regarding use services access within WA relates to inpatient services (separations) and Emergency Department attendances. This data is not an accurate representation of the number of women who accessed perinatal depression services in Western Australia .
