PLANS & PRICING
A nurse or a midwife cannot work outside their scope of practice. Before this, anyone who wanted to be a midwife had to first be a nurse and undertake a 12 month training program (hospital based at first, then by universities when education was shifted from the hospitals to the universities). They are essentially separate, but related, professions.
A nurse or a midwife can gain extra post-graduate qualifications to become Nurse or Midwife Practitioners (they can diagnose a limited number of conditions, order a limited scope of treatments, and prescribe some medication). They can also undertake higher degree programs (Masters, Doctorate) in their fields.
Most midwives work within hospitals and midwifery group practices, and a small number are independent. Midwives are autonomous practitioners who can order scans/tests, prescribe some medication in the scope of "low risk" maternity care (ie: antibiotics for UTI, treatment for some STIs, folic acid/iron/iodine supplements), and can choose to work independently (their own caseload) or as core staff in a hospital (working set hours on a rotating shift roster).
