INTRODUCTIONFebrile neutropenia (FN) remains a major cause of morbidity and mortality in Oncology/Haematology units. We launched a new protocol for FN management that incorporates risk stratification at our institute from October 2008. An audit was performed concurrently to evaluate the protocol and to define the epidemiology of FN locally.
MATERIALS AND METHODSCase records of all inpatients with FN between October 2008 and June 2009 were reviewed prospectively. Clinical and microbiological characteristics were collated along with outcomes and programme adherence. Statistical testing was performed using Stata 10.1.
RESULTSThere were 178 FN episodes (50 in patients with solid cancers) from 131 patients. Forty-two (23.6%) episodes were classified as high-risk according to MASCC criteria. Initial blood cultures were positive in 49 (27.5%) episodes, of which gram-negative bacilli (GNB) predominated. Overall compliance to the protocol was 56.7%, with the main issue being disinclination to use oral antibiotics as fi rst-line empirical therapy for low-risk episodes. Overall mortality was 7.3% and infection-related mortality was 4.5%. High-risk FN and the presence of central venous catheters were independently associated with bacteraemia on multivariate analysis, but there were no independent predictors of infection-related mortality.
CONCLUSIONSGNB accounted for the majority of bloodstream infections at our institute, unlike data from developed countries. Uptake of the new FN protocol was satisfactory, although the use of oral antibiotics as fi rst-line empirical therapy can be improved. A better method for predicting infections caused by antibiotic-resistant GNB is urgently required, and antibiotic resistance trends should be monitored to enable the implementation of more appropriate antibiotic regimens over time.

INTRODUCTIONFebrile neutropenia (FN) is a significant cause of mortality and morbidity in oncology and haematology units worldwide. The overall mortality in hospital surveys in Singapore surveys on post-chemotherapy FN has ranged between 3.0% and 8.8%. However, recent evidence indicates that outpatient management of patients with low-risk FN is safe and cost-effective.
MATERIALS AND METHODSWe conducted a prospective audit on a cohort of adult patients with post-chemotherapy FN seen at 2 local public sector cancer centres over a 1-year period in order to define their epidemiological characteristics and outcomes, and also to assess the uptake of early discharge/outpatient management strategies for these patients.
RESULTSWe reviewed 306 FN episodes from 248 patients. Patient characteristics and outcomes were similar between both institutions. Eleven (3.7%) FN episodes were managed as outpatient and none developed complications. Overall 30-day mortality was 6.6%, while the median length of stay (LOS) was 7 days (IQR: 4 to 11 days). The only independent risk factor for mortality was severe sepsis (OR:13.19; 95% CI: 1.98 to 87.7; P = 0.008). Factors independently associated with a longer LOS were vancomycin prescription (coefficient: 0.25; 95% CI: 0.08 to 0.41; P = 0.003), longer duration of intravenous antibiotics (coefficient: 0.08; 95% CI: 0.06 to 0.10; P <0.001), and prior review by an infectious diseases physician (coefficient: 0.16; 95% CI: 0.01 to 0.31; P = 0.034).
CONCLUSIONThis audit demonstrated that mortality from FN in our 2 cancer centres is low and comparable to international institutions. It also demonstrates that outpatient management of FN is safe in selected patients, and can be further expanded for right-siting of resources.
