Cancer inpatients morphine usage: a new England area survey.

This is a one year study of the use of morphine in cancer patients in 10 inpatient facilities in the New England Area Health Service in the north-west of New South Wales. The study explored 170 admissions relating to 122 patients, most of whom were cared for by their general practitioners. The use of morphine in these cancer patients was compared with the recommendations made by the expert working group of the European Association of Palliative Care.1 Those items which matched the recommendations included the initial doses for new users of morphine and the subcutaneous route being the preferred parenteral route. The data in this study differed from the recommendations in that only half of the patients received the immediate release morphine when first given oral morphine, only 43% had orders for immediate release oral morphine for breakthrough pain (with a variable frequency) and a significant number of orders for parenteral and immediate release oral morphine for breakthrough pain were outside the recommended doses (100% and 86.2%, respectively). Written orders for immediate release oral and parenteral morphine involved a dose range in significant numbers while only 30% of patients had orders for parenteral morphine for breakthrough pain. There was a low use of fixed interval variable dose (FIVD) morphine charts despite these being available in most facilities.
