This week I will be submitting the final two assignments for the course. Once the results have been finalised I will be able to apply for a prescriber number. Here's the process (I like to record the links here so that I can refer back to it when I need to, or if anyone asks me about the course):
Applications
forms are available from the AHPRA website:
Once I have a prescriber number I can register to receive
the Australian Prescriber journal,
which is free to all Australian prescribers. Details are available from their
website: www.australianprescriber.com.
One of the areas of 'extension' to my knowledge that I have experienced in completing this course is a better understanding of the relatively simple and routine investigations that are done for healthy women in their pregnancies. For example, blood tests that detect anaemia, (FBE and Iron studies), and understanding when anaemia is best treated with iron supplements.
The wonderful web has given me access to good sites that I might not have accessed otherwise. For example, from the UK GP Notebook site:
The mean minimum value for haemoglobin accepted by the World
Health Organisation is 11.0 g/dl (at sea level). A woman with haemoglobin
levels below this value that occur during pregnancy has, by definition, anaemia
in pregnancy.
Anaemia in pregnancy is more common in patients who are already
anaemic at conception e.g. patients with haemoglobinopathies, poor diet, with a
history of menorrhagia. Women with a multiple pregnancy are more prone to the
development of anaemia.
During the antenatal period Hb estimation are routinely taken at
booking, 28, 32 and 36 weeks. An iron deficiency anaemia will exhibit a low
serum iron and raised total iron binding capacity, with a hypochromic microcytic
film and low serum ferritin.
Comments on ferritin, from Melbourne Haematology
Small amount of circulating serum
ferritin reflects body iron stores. Is
now well established in assessment of iron stores
Normal
range 15 – 300 ug/l (reference ranges
vary depending on the method used)
Levels
< 15 ug/l reflect absent / reduced iron stores
Note on Haemoglobin:
NICE (2008) advises that Hb below 11g/dL in early pregnancy (at first contact) and 10.5 g/dl
at 28 weeks should be investigated and Fe supplementation considered.
The fall in Hb during pregnancy, indicating a
healthy plasma volume expansion, does not indicate the need for Fe
supplementation. (Little et al 2005)
There is a considerable variation in the
Reference values for low (100-115) and high (137-165)
From the South Australia Health Department's site
Anaemia with a
low MCV that does not respond to iron supplementation should be investigated
with iron studies. True iron deficiency is characterised by the following
taking all parameters into account:
> Low ferritin (< 15 mg / L)
> High transferrin (> 5.56 mmol / L)
concentration (transferrin levels are higher in than outside pregnancy)
> Low serum iron (< 8 mmol / L)
> Low transferrin saturation (< 10 %)
