Improving the emergency department management of post-chemotherapy sepsis in haematological malignancy patients.

OBJECTIVE: To review the result of the implementation of treatment protocol for post-chemotherapy sepsis in haematological malignancy patients. DESIGN: Case series with internal comparison. SETTING: Accident and Emergency Department, Queen Elizabeth Hospital, Hong Kong. PATIENTS: Febrile patients presenting to the Accident and Emergency Department with underlying haematological malignancy and receiving chemotherapy within 1 month of Accident and Emergency Department visit between June 2011 and July 2012. Similar cases between June 2010 and May 2011 served as historical referents. MAIN OUTCOME MEASURES: The compliance rate among emergency physicians, the door-to-antibiotic time before and after implementation of the protocol, and the impact of the protocol on Accident and Emergency Department and hospital service. RESULTS: A total of 69 patients were enrolled in the study. Of these, 50 were managed with the treatment protocol while 19 patients were historical referents. Acute myeloid leukaemia was the most commonly encountered malignancy. Overall, 88% of the patients presented with sepsis syndrome. The mean door-to-antibiotic time of those managed with the treatment protocol was 47 minutes versus 300 minutes in the referent group. Overall, 86% of patients in the treatment group met the target door-to-antibiotic time of less than 1 hour. The mean lengths of stay in the emergency department (76 minutes vs 105 minutes) and hospital (11 days vs 15 days) were shorter in those managed with the treatment protocol versus the historical referents. CONCLUSION: Implementation of the protocol can effectively shorten the door-to-antibiotic time to meet the international standard of care in neutropenic sepsis patients. The compliance rate was also high. We proved that effective implementation of the protocol is feasible in a busy emergency department through excellent teamwork between nurses, pharmacists, and emergency physicians.

The benefit of prothrombin complex concentrate in decreasing neurological deterioration in patients with warfarin-associated intracerebral haemorrhage.

OBJECTIVE: To compare the outcomes of patients with warfarin-associated intracerebral haemorrhage given different treatments to reverse the effect of anticoagulation. DESIGN: Historical cohort study. SETTING: A regional hospital in Hong Kong. PATIENTS: Patients on warfarin who developed intracerebral haemorrhage. INTERVENTIONS: Prothrombin complex concentrate versus fresh frozen plasma treatment. MAIN OUTCOME MEASURES: The primary outcome measures included the international normalised ratio before and after prothrombin complex concentrate treatment and the neurological deterioration in patients with Glasgow Coma Scale score of more than 8/not intubated/not planned for immediate surgery (target group). Secondary outcome measures were haematoma expansion, 7-day and 30-day mortality rates, and 3-month functional outcome. Safety outcome was the occurrence of a thrombotic event after prothrombin complex concentrate treatment within the index admission. RESULTS: Among 33 patients with clearly documented time of infusion of prothrombin complex concentrate, and whose international normalised ratio was checked before and after prothrombin complex concentrate treatment, the mean international normalised ratio was reduced from 2.81 to 1.21 within 24 hours. Within the target group of patients, there was a significantly lower rate of neurological deterioration in the prothrombin complex concentrate group (17.4% of 23 patients) versus fresh frozen plasma group (45.5% of 33 patients) [P=0.027]. In terms of the 7-day mortality, 30-day mortality, and 3-month functional outcome, prothrombin complex concentrate-treated group showed a favourable trend although the difference did not reach a statistical significance. No patient developed thrombotic complications after prothrombin complex concentrate treatment. CONCLUSIONS: Prothrombin complex concentrates can reverse the warfarin effect of prolonged international normalised ratio in a timely manner. It might better improve the outcome of warfarin-associated intracerebral haemorrhage compared with fresh frozen plasma treatment by reduction in neurological deterioration.
