Guaranteeing accountability for quality care.

The quality gap in the management of chronic disease is an issue which must be addressed if we are to achieve sustainability of our health system and optimal health outcomes for Canadians. The delivery of quality care needs to be a fundamental expectation of providers, professional regulators, institutional leaders and senior government leaders. Success in the arena of quality improvement comes from clarity of accountability, "obsessive" tracking and action on key performance indicators, and results-based teamwork. Strong leadership, identification of shared priorities across the country, full transparency, and an engaged public are all key to moving ahead in this critical area of Canadian healthcare.

Hereditary angioedema managed with low-dose danazol and C1 esterase inhibitor concentrate: a case report.

BACKGROUND: Hereditary angioedema (HAE) is a rare life-threatening disease that can occur in pregnancy. CASE: A nulliparous woman was diagnosed as having HAE at 22 weeks of gestation after a series of symptomatic episodes. Following an initial course of C1 esterase inhibitor (C1EI) therapy for an acute episode of HAE, she was treated with danazol for prophylaxis. Danazol did not prevent recurrence of symptoms, its use was discontinued after six weeks. Thereafter, the patient was treated exclusively with C1EI at weekly intervals for exacerbations of her HAE. At 37 weeks' gestation, she delivered healthy 3050 g female neonate. At the time of discharge the female neonate had no signs of virilization or congenital anomalies. CONCLUSION: Low dose danazol was ineffective in treating this woman's HAE in pregnancy. The use of C1EI in pregnancy is associated with good outcomes.

Treatment of antiphospholipid antibody syndrome (APS) in pregnancy: a randomized pilot trial comparing low molecular weight heparin to unfractionated heparin.

OBJECTIVE: To compare low molecular weight heparin (LMWH), specifically dalteparin, to unfractionated heparin (UFH) for the treatment of antiphospholipid antibody syndrome (APS) in pregnancy. METHODS: In a tertiary referral centre, 28 women met the 1999 International Consensus Criteria for APS, based on their obstetrical history and APS serology. The women were randomized, using a random numbers table with blocks of 12, to receive either prophylactic dosing of dalteparin or UFH starting either preconceptionally or early in pregnancy. All women also received low-dose acetylsalicylic acid, started preconceptionally. The primary outcome was a live birth. The secondary outcomes were maternal and fetal complications. RESULTS: Of the 14 women who received the LMWH, dalteparin, and the 14 women who received UFH, 1 woman in each group did not conceive. Nine of the 13 women (69%) given dalteparin had a successful pregnancy (95% confidence interval [CI], 39-91%), compared to 4 out of the 13 women (31%) in the UFH group (95% CI, 9-61%). Nine women in total had spinal or epidural anaesthesia, and there were no complications overall. CONCLUSION: Dalteparin may be an effective alternative to UFH for treatment of APS in pregnancy. A multicentre randomized trial is needed to determine benefit-to-risk ratios for the use of dalteparin and UFH to treat this high-risk obstetrical condition. Pharmacokinetic and pharmacodynamic studies are also recommended to maximize therapeutic response and minimize toxicity.
