BackgroundEconomic implications of chemotherapy-induced febrile neutropenia (FN) in European and Australian clinical practice are largely unknown.MethodsData were obtained from a European (97%) and Australian (3%) observational study of patients with non-Hodgkin’s lymphoma (NHL) receiving CHOP (±rituximab) chemotherapy. For each patient, each cycle of chemotherapy within the course, and each occurrence of FN within cycles, was identified. Patients developing FN in a given cycle (“FN patients”), starting with the first, were matched to those who did not develop FN in that cycle (“comparison patients”), irrespective of subsequent FN events. FN-related healthcare costs (£2010) were tallied for the initial FN event as well as follow-on care and FN events in subsequent cycles.ResultsMean total cost was £5776 (95%CI £4928-£6713) higher for FN patients (n = 295) versus comparison patients, comprising £4051 (£3633-£4485) for the initial event and a difference of £1725 (£978-£2498) in subsequent cycles. Among FN patients requiring inpatient care (76% of all FN patients), mean total cost was higher by £7259 (£6327-£8205), comprising £5281 (£4810-£5774) for the initial hospitalization and a difference of £1978 (£1262-£2801) in subsequent cycles.ConclusionsCost of chemotherapy-induced FN among NHL patients in European and Australian clinical practice is substantial; a sizable percentage is attributable to follow-on care and subsequent FN events.

BackgroundStress-related hyperglycaemia (SHG) is commonly seen in acutely ill patients and has been associated with poor outcomes in many studies performed in different acute care settings. We aimed to review the available evidence describing the associations between SHG and different outcomes in acutely ill patients admitted to an ICU. Study designs, populations, and outcome measures used in observational studies were analysed.MethodsWe conducted a systematic scoping review of observational studies following the Joanna Briggs methodology. Medline, Embase, and the Cochrane Library were searched for publications between January 2000 and December 2015 that reported on SHG and mortality, infection rate, length of stay, time on ventilation, blood transfusions, renal replacement therapy, or acquired weakness.ResultsThe search yielded 3,063 articles, of which 43 articles were included (totalling 536,476 patients). Overall, the identified studies were heterogeneous in study conduct, SHG definition, blood glucose measurements and monitoring, treatment protocol, and outcome reporting. The most frequently reported outcomes were mortality (38 studies), ICU and hospital length of stay (23 and 18 studies, respectively), and duration of mechanical ventilation (13 studies). The majority of these studies (40 studies) compared the reported outcomes in patients who experienced SHG with those who did not. Fourteen studies (35.9%) identified an association between hyperglycaemia and increased mortality (odds ratios ranging from 1.13 to 2.76). Five studies identified hyperglycaemia as an independent risk factor for increased infection rates, and one identified it as an independent predictor of increased ICU length of stay.DiscussionSHG was consistently associated with poor outcomes. However, the wide divergences in the literature mandate standardisation of measuring and monitoring SHG and the creation of a consensus on SHG definition. A better comparability between practices will improve our knowledge on SHG consequences and management.

ObjectivesGastrointestinal (GI) intolerance is associated with adverse outcomes in critically ill patients receiving enteral nutrition (EN). The objective of this analysis is to quantify the cost of GI intolerance and the cost implications of starting with semi-elemental EN in intensive care units (ICUs).Study designA US-based cost–consequence model was developed to compare the costs for patients with and without GI intolerance and the costs with semi-elemental or standard EN while varying the proportion of GI intolerance cases avoided.Materials and methodsICU data on GI intolerance prevalence and outcomes in patients receiving EN were derived from an observational study. ICU stay costs were obtained from literature and the costs of EN from US customers’ price lists. The model was used to conduct a threshold analysis, which calculated the minimum number of cases of GI intolerance that would have to be avoided to make the initial use of semi-elemental formula cost saving for the cohort.ResultsOut of 100 patients receiving EN, 31 had GI intolerance requiring a median ICU stay of 14.4 days versus 11.3 days for each patient without GI intolerance. The model calculated that semi-elemental formula was cost saving versus standard formula when only three cases of GI intolerance were prevented per 100 patients (7% of GI intolerance cases avoided).ConclusionIn the US setting, the model predicts that initial use of semi-elemental instead of standard EN can result in cost savings through the reduction in length of ICU stay if >7% of GI intolerance cases are avoided.
