Nova Scotia Provincial Blood Coordinating Program


The Department of Health and Wellness continuously strives to make sure that Nova Scotians receive safe, quality health care and health-care services. There are many programs and projects that specifically address safeguarding our health care system. The Provincial Blood Coordinating Program is one of them.

The Provincial Blood Coordinating Program was created in January 2003 and provides the leadership to collaborate with health care providers across the province and Canadian Blood Services to maximize the safe and appropriate management of blood and related products received by Nova Scotians.

[1]  NSPBCP gratefully acknowledges the Pharmacy Department of Sunnybrook Health Sciences Centre for the use of their template for the Adjusted Body Weight Calculator. The NSPBCP made the following modifications:

·        There is no upper limit of actual weight for the dose calculations

·        Dosage increments of 0.1, 0.2 and 0.3gm/kg in addition to 0.4 and 1gm/kg

[2] Ideal Body Weight (IBW), Devine Formula is:
         Ideal Body Weight (male) = 50.0 kg + 2.3 kg (each inch > 5 feet)
       Ideal Body Weight (female) = 45.5 kg + 2.3 kg (each inch > 5 feet)

[3] Dosing Weight is an adjusted body weight (of obese or overweight patients) and should only be used to calculate the dose of drugs for which there are recommendations specifying that the actual body weight should be adjusted for use in the dose calculations.
 
  • Dosing Weight = IBW + [0.4 x (Actual - IBW)]
  • exception:  if Actual < IBW,  then Dosing Weight = Actual
  • (Actual = actual body weight)
