[Evaluation of primary care treatment of oncology patients with opiates].

Objectives: To evaluate how adequately pain in terminal cancer patients is managed by morphine taken orally.

Design: A descriptive, retrospective study, from January 1993 to March 1994.

Setting: Primary care. Four primary care teams of the 10th Health Area of Madrid.

Patients: 37 patients with terminal cancer who took morphine under the supervision of primary care doctors.

Measurements And Main Results: Average age was 64.6 +/- 14. The most common site of the primary tumour was lungs (n = 6), colon (n = 4) and stomach (n = 4). All the patients received conventional analgesics at first and 82% went on to weak opiates before progressing to morphine. Half the patients began with an oral solution of morphine and the other half with long-acting tablets. Increases in the doses of morphine were correct in 62% of cases. 41% of the patients took antiemetics and 55% laxatives. 82% of the bone and 100% of the brain metastases were correctly treated.

Conclusions: In general, primary care doctors in our area correctly handle pain caused by terminal cancer. The most significant errors are to do with increases in doses of morphine and with the associated use of laxatives. These can easily be rectified so that our patients' quality of life can be improved.
