Net ultrafiltration prescription survey in Europe.

ABSTRACT: BACKGROUND:Fluid overload is common in patients in the intensive care unit (ICU) and ultrafiltration (UF) is frequently required. There is lack of guidance on optimal UF practice. We aimed to explore patterns of UF practice, barriers to achieving UF targets, and concerns related to UF practice among practitioners working in Europe. METHODS:This was a sub-study of an international open survey with focus on adult intensivists and nephrologists, advanced practice providers, and ICU and dialysis nurses working in Europe. RESULTS:Four hundred eighty-five practitioners (75% intensivists) from 31 countries completed the survey. The most common criteria for UF initiation was persistent oliguria/anuria (45.6%), followed by pulmonary edema (16.7%). Continuous renal replacement therapy was the preferred initial modality (90.0%). The median initial and maximal rate of net ultrafiltration (UF^NET) prescription in hemodynamically stable patients were 149?mL/hr. (IQR 100-200) and 300?mL/hr. (IQR 201-352), respectively, compared to a median UF^NET rate of 98?mL/hr. (IQR 51-108) in hemodynamically unstable patients and varied significantly between countries. Two-thirds of nurses and 15.5% of physicians reported assessing fluid balance hourly. When hemodynamic instability occurred, 70.1% of practitioners reported decreasing the rate of fluid removal, followed by starting or increasing the dose of a vasopressor (51.3%). Most respondents (90.7%) believed in early fluid removal and expressed willingness to participate in a study comparing protocol-based fluid removal versus usual care. CONCLUSIONS:There was a significant variation in UF practice and perception among practitioners in Europe. Future research should focus on identifying the best strategies of prescribing and managing ultrafiltration in critically ill patients.

Project description:BackgroundAlthough net ultrafiltration (UFNET) is frequently used for treatment of fluid overload in critically ill patients with acute kidney injury, the optimal intensity of UFNET is unclear. Among critically ill patients with fluid overload receiving renal replacement therapy (RRT), we examined the association between UFNET intensity and risk-adjusted 1-year mortality.MethodsWe selected patients with fluid overload ≥ 5% of body weight prior to initiation of RRT from a large academic medical center ICU dataset. UFNET intensity was calculated as the net volume of fluid ultrafiltered per day from initiation of either continuous or intermittent RRT until the end of ICU stay adjusted for patient hospital admission body weight. We stratified UFNET as low (≤ 20 ml/kg/day), moderate (> 20 to ≤ 25 ml/kg/day) or high (> 25 ml/kg/day) intensity. We adjusted for age, sex, body mass index, race, surgery, baseline estimated glomerular filtration rate, oliguria, first RRT modality, pre-RRT fluid balance, duration of RRT, time to RRT initiation from ICU admission, APACHE III score, mechanical ventilation use, suspected sepsis, mean arterial pressure on day 1 of RRT, cumulative fluid balance during RRT and cumulative vasopressor dose during RRT. We fitted logistic regression for 1-year mortality, Gray's survival model and propensity matching to account for indication bias.ResultsOf 1075 patients, the distribution of high, moderate and low-intensity UFNET groups was 40.4%, 15.2% and 44.2% and 1-year mortality was 59.4% vs 60.2% vs 69.7%, respectively (p = 0.003). Using logistic regression, high-intensity compared with low-intensity UFNET was associated with lower mortality (adjusted odds ratio 0.61, 95% CI 0.41-0.93, p = 0.02). Using Gray's model, high UFNET was associated with decreased mortality up to 39 days after ICU admission (adjusted hazard ratio range 0.50-0.73). After combining low and moderate-intensity UFNET groups (n = 258) and propensity matching with the high-intensity group (n = 258), UFNET intensity > 25 ml/kg/day compared with ≤ 25 ml/kg/day was associated with lower mortality (57% vs 67.8%, p = 0.01). Findings were robust to several sensitivity analyses.ConclusionsAmong critically ill patients with ≥ 5% fluid overload and receiving RRT, UFNET intensity > 25 ml/kg/day compared with ≤ 20 ml/kg/day was associated with lower 1-year risk-adjusted mortality. Whether tolerating intensive UFNET is just a marker for recovery or a mediator requires further research.

Project description:INTRODUCTION:Tumor necrosis factor inhibitors (TNFi) are commonly used as first-line therapy (biologic disease-modifying antirheumatic drug [bDMARD] and targeted synthetic DMARD [tsDMARD]: defined as targeted therapy) for patients with moderate-to-severe rheumatoid arthritis (RA), usually combined with conventional synthetic DMARDs (csDMARDs) but sometimes as monotherapy. If treatment fails, patients cycle to another TNFi (cycling) or switch to a targeted therapy with a different mode of action (MOA; switching). The study aimed to examine prescribing patterns and reasons for current RA treatment practice in Europe (EU5: France, Germany, Italy, Spain, UK) and Japan. METHODS:Data were collected from the Adelphi Disease Specific Programme™ (DSP; Q1-Q2 2017). Rheumatologists seeing ≥ 10 (EU5) and ≥ 5 (Japan) patients with RA a month completed Patient Record Forms. Patients ≥ 18 years old, with RA diagnosis and complete RA-targeted therapy history were included. Patients were grouped based on first-line targeted therapy class, and on whether first-line targeted therapy was monotherapy (targeted therapy alone) or combination therapy (targeted therapy and csDMARD). Those patients receiving TNFi at first-line and with ≥ 1 targeted therapy were classified as TNFi cyclers or MOA switchers. Univariate analysis compared factors across groups. Patient demographics and characteristics compared across groups; physician reasoning for targeted therapy change; and time to discontinuation of targeted therapy. RESULTS:In EU5 and Japan, respectively, 1741 and 147 patients were included; at first-line, 80.8% and 64.6% received TNFi and 76.0% and 77.6% received combination therapy. Overall in EU5, more combination therapy than monotherapy patients reached maximum csDMARD dose before first-line targeted therapy (P < 0.05); disease severity was higher in patients initiating TNFi versus non-TNFi (P < 0.05). In Japan, trends were similar but not significant. The most common reason physicians gave for changing therapy following first-line targeted therapy was 'secondary lack of efficacy' (EU5: 46.2%; Japan: 53.8%). In EU5 and Japan, respectively, of 365 and 22 patients who received second-line targeted therapy, 52.1% and 54.5% were MOA switchers. In EU5, TNFi cyclers had longer time from diagnosis to second-line targeted therapy initiation than MOA switchers (P = 0.04). CONCLUSIONS:TNFis were the most commonly prescribed targeted therapy at first-line. Between 10 and 20% of patients prescribed a TNFi as first-line targeted therapy did so without concomitant csDMARD. Almost half of patients cycled to another TNFi at second-line.
