table is to be selected when the endocrine disorder is not associated with loss of function. If an assessable loss of function occurs in another system the higher rating is to be chosen. The two are not to be combined.

PART 12.2: THE HAEMOPOIETIC SYSTEM

Conditions of the haemopoietic system include anaemias, leukaemias and polycythaemia.

Haemopoietic conditions usually affect various other body systems, therefore loss of function for the condition is to be established by assessing the effect of the condition on those body systems. Some haemopoeitic conditions are also malignant conditions and may be assessed by applying Chapter 14 (Malignant Conditions). For very severe haemopoietic conditions, where many body systems are affected, Tables 16.1 and 16.2 in Chapter 16 (Activities of Daily Living) are also to be applied to rate the loss of function.

Many anaemias will respond adequately to replacement or supplemental therapy. For example, the hypochromic anaemia of iron deficiency will usually respond to dietary iron supplementation and pernicious anaemia will usually respond to parenteral Vitamin B12.

Calculation of the impairment rating for loss of haemopoietic function

Follow the steps below to calculate the impairment rating due to accepted loss of haemopoietic function:

(Each step is elaborated on the following page.)

STEP 1  Establish which body systems are affected by the accepted haemopoietic condition.                                        Page 164
STEP 2  Determine the impairment rating for functional impairment of the affected body systems.                                  Page 164
STEP 3  Determine the impairment rating for the treatment requirements of the haemopoietic condition by applying Table 12.2.1.   Page 165

Step 1: Establish which body systems are affected by the accepted haemopoietic condition.

Haemopoietic conditions may affect the function of other body systems.  For example, refractory anaemia may result in reduced effort tolerance.

Step 2: Determine the functional impairment of all body systems affected by the haemopoietic condition.

Apply the appropriate functional impairment table elsewhere in this Guide to assess the functional impairment arising from the haemopoietic condition. For example, in the case of refractory anaemia causing reduced effort tolerance, the reduced effort tolerance is to be assessed by use of the Effort Tolerance protocol in Chapter 1.

If non-accepted conditions have contributed to the impairment rating for any of the affected body systems, Chapter 19 (Partially Contributing Impairment) is to be applied.

The various functional impairment ratings are not combined at this stage but are to be included in the final combining of all impairment ratings.

Step 3: Determine the impairment rating for the treatment requirements of the accepted haemopoietic condition using Table 12.2.1.

The ratings obtained in Steps 2 and 3 are not to be combined at this stage but both are to be included in
