RESUMO

BACKGROUND: Malnutrition among women of childbearing age is especially prevalent in Asia and sub-Saharan Africa and can be harmful to the fetus during pregnancy. In the most recently available Demographic and Health Survey (DHS), approximately 10% to 20% of pregnant women in India, Pakistan, Mali, and Tanzania were undernourished (body mass index [BMI] <18.5 kg/m2), and according to the Global Burden of Disease (GBD) 2017 study, approximately 20% of babies were born with low birth weight (LBW; <2,500 g) in India, Pakistan, and Mali and 8% in Tanzania. Supplementing pregnant women with micro and macronutrients during the antenatal period can improve birth outcomes. Recently, the World Health Organization (WHO) recommended antenatal multiple micronutrient supplementation (MMS) that includes iron and folic acid (IFA) in the context of rigorous research. Additionally, WHO recommends balanced energy protein (BEP) for undernourished populations. However, few studies have compared the cost-effectiveness of different supplementation regimens. We compared the cost-effectiveness of MMS and BEP with IFA to quantify their benefits in 4 countries with considerable prevalence of maternal undernutrition. METHODS AND FINDINGS: Using nationally representative estimates from the 2017 GBD study, we conducted an individual-based dynamic microsimulation of population cohorts from birth to 2 years of age in India, Pakistan, Mali, and Tanzania. We modeled the effect of maternal nutritional supplementation on infant birth weight, stunting and wasting using effect sizes from Cochrane systematic reviews and published literature. We used a payer's perspective and obtained costs of supplementation per pregnancy from the published literature. We compared disability-adjusted life years (DALYs) and incremental cost-effectiveness ratios (ICERs) in a baseline scenario with existing antenatal IFA coverage with scenarios where 90% of antenatal care (ANC) attendees receive either universal MMS, universal BEP, or MMS + targeted BEP (women with prepregnancy BMI <18.5 kg/m2 receive BEP containing MMS while women with BMI ≥18.5 kg/m2 receive MMS). We obtained 95% uncertainty intervals (UIs) for all outputs to represent parameter and stochastic uncertainty across 100 iterations of model runs. ICERs for all scenarios were lowest in Pakistan and greatest in Tanzania, in line with the baseline trend in prevalence of and attributable burden to LBW. MMS + targeted BEP averts more DALYs than universal MMS alone while remaining cost-effective. ICERs for universal MMS compared to baseline IFA were $52 (95% UI: $28 to $78) for Pakistan, $72 (95% UI: $37 to $118) for Mali, $70 (95% UI: $43 to $104) for India, and $253 (95% UI: $112 to $481) for Tanzania. ICERs for MMS + targeted BEP compared to baseline IFA were $54 (95% UI: $32 to $77) for Pakistan, $73 (95% UI: $40 to $104) for Mali, $83 (95% UI: $58 to $111) for India, and $245 (95% UI: $127 to $405) for Tanzania. Study limitations include generalizing experimental findings from the literature to our populations of interest and using population-level input parameters that may not reflect the heterogeneity of subpopulations. Additionally, our microsimulation fuses multiple sources of data and may be limited by data quality and availability. CONCLUSIONS: In this study, we observed that MMS + targeted BEP averts more DALYs and remains cost-effective compared to universal MMS. As countries consider using MMS in alignment with recent WHO guidelines, offering targeted BEP is a cost-effective strategy that can be considered concurrently to maximize benefits and synergize program implementation.

RESUMO

Our study investigated whether pre-operative screening and treatment for anaemia and suboptimal iron stores in a patient blood management clinic is cost effective. We used outcome data from a retrospective cohort study comparing colorectal surgery patients admitted pre- and post-implementation of a pre-operative screening programme. We applied propensity score weighting techniques with multivariable regression models to adjust for differences in baseline characteristics between groups. Episode-level hospitalisation costs were sourced from the health service clinical costing data system; the economic evaluation was conducted from a Western Australia Health System perspective. The primary outcome measure was the incremental cost per unit of red cell transfusion avoided. We compared 441 patients screened in the pre-operative anaemia programme with 239 patients not screened; of the patients screened, 180 (40.8%) received intravenous iron for anaemia and suboptimal iron stores. The estimated mean cost of screening and treating pre-operative anaemia was AU$332 (£183; US$231; €204) per screened patient. In the propensity score weighted analysis, screened patients were transfused 52% less red cell units when compared with those not screened (rate ratio = 0.48, 95%CI 0.36-0.63, p < 0.001). The mean difference in total screening, treatment and hospitalisation cost between groups was AU$3776 lower in the group screened (£2080; US$2629; €2325) (95%CI AU$1604-5947, p < 0.001). Screening elective patients pre-operatively for anaemia and suboptimal iron stores reduced the number of red cell units transfused. It also resulted in lower total costs than not screening patients, thus demonstrating cost effectiveness.

RESUMO

BACKGROUND: Oral iron is recommended as first line treatment of anemia in non-dialysis chronic kidney disease (ND-CKD) patients. Sucrosomial® iron, a new generation oral iron with high absorption and bioavailability and a low incidence of side effects, has shown to be not inferior to intravenous (IV) iron in the replacement of iron deficiency anemia in patients with ND-CKD. Besides the clinical benefit, it is also important to determine the comparative total costs of oral versus IV iron administrations. The aim of this study was to perform a cost-minimization analysis of oral Sucrosomial iron, compared with IV iron gluconate from an Italian societal perspective. METHODS: Cost analysis was performed on the 99 patients with ND-CKD and iron-deficiency anemia of the randomized trial by Pisani et al. Human and material resources utilization was recorded during each iron administration. According to study perspective, direct and indirect costs were considered. Costs for each resource unit were taken from official Italian sources. Probabilistic sensitivity analyses were carried out to test the robustness of the results. RESULTS: The base case analysis showed an average cost/cycle per patient of € 111 for oral iron and € 1302 for IV iron. Thus, the potential saving was equal to € 1191 per patient/cycle. The sensitivity analysis showed that the most sensitive driver is the time loss by patient and caregivers for the therapy and related-care, followed by the minutes of nursing care and the number of kilometres travelled to reach the referral centre. DISCUSSION: This study showed that oral Sucrosomial® iron could offer specific advantages in terms of potential savings, and allowed identifying some implications for future research. Such advantages still persist with the new single dose IV iron formulation available in the market, although to a lesser extent.

RESUMO

BACKGROUND: Moderate to severe iron deficiency anaemia is a common finding in patients admitted to the Emergency Department (ED). According to Patient Blood Management principles, intravenous iron should be the therapy of choice instead of blood transfusion for selected cases affected by chronic iron deficiency anaemia. However, this option is only rarely taken into account by physicians in the ED. As a result, in many circumstances, treatment of iron deficiency anaemia in the ED can differ from that of the Anaemia Clinic. With the aim of reducing inappropriate transfusions, and to implement intravenous iron usage, we shared a specific protocol with the ED. MATERIAL AND METHODS: We reviewed the medical records of all subjects admitted to the ED (n=267, Post-protocol group) with hemoglobin ≤9.0 g/dL and mean corpuscular volume <80 fL in a 13-month period, except if the massive transfusion protocol was activated, and results were compared with an equivalent Pre-protocol historical cohort (n=226). RESULTS: In comparison with the Pre-protocol series, the number of patients transfused did not change, but the appropriateness in terms of transfusion and red blood cell volume transfused improved sharply (87.0 vs 13.3%; p<0.001) with a significant increase in intravenous iron administration (50.2 vs 4.4% of cases; p<0.001). As a positive consequence, both the time spent in the ED by patients who were then directly discharged and costs per subject treated dropped by 37.9% and 59.0%, respectively. Treatment with infusion only in comparison with transfusion only led to a statistically significant Relative Risk reduction in transfusion on the ward and post-discharge transfusion of 55.6% and 44.4%, respectively. DISCUSSION: The implementation of Patient Blood Management principles and early intravenous iron therapy in the Emergency Department have proved to be effective tools to optimise resources both in terms of units transfused and costs.

RESUMO

We present a process map for the implementation of a program to treat preoperative anemia utilizing 1 existing anesthesiologist in the preoperative evaluation clinic. In the first 7 months postimplementation, 342 patients were screened for anemia, 166 were diagnosed, and 107 were treated. The mean increase in hemoglobin in treated patients was ~2 g/dL (range 0-4.9 g/dL). Two patients' surgeries were delayed in favor of treatment and 3 surgical patients, who had received 2 complete iron infusions, received an intraoperative transfusion. The total revenue generated for the institution was enough to subsidize the cost of an additional anesthesiologist.

RESUMO

Anemia is a common finding in patients with heart failure (HF). The cause for anemia is multifactorial, with iron deficiency being the most common cause. Anemia with HF is an established predictor of morbidity and mortality. Iron deficiency in systolic HF, even without anemia, has been associated with increased mortality, increased hospitalizations, and decreased functional capacity and quality of life measures. Data from several randomized controlled trials and meta-analyses of iron deficiency and systolic HF show a beneficial effect for intravenous (IV) iron in terms of quality of life and functional capacity (improvements in 6-min walk test, and improvements in New York Heart Association functional class), as well as decreased hospitalizations for HF and reduction in cardiovascular mortality rates. Limited evidence exists for a beneficial effect of IV iron in diastolic dysfunction. Patients with symptomatic systolic HF should undergo an anemia diagnostic work-up. When iron deficiency (defined as ferritin <100 ng/mL or serum ferritin 100-299 ng/mL and transferrin saturation <20%) is present, current evidence supports treating HF patients with iron deficiency with IV iron.

RESUMO

Aims: The overall cost and health-related quality of life (HRQoL) associated with current treatments for chronic kidney disease (CKD)-related anemia are not well characterized. A systematic literature review (SLR) was conducted on the costs and HRQoL associated with current treatments for CKD-related anemia among dialysis-dependent (DD) patients. Materials and methods: The authors searched the Cochrane Library, MEDLINE, EMBASE, NHS EED, and NHS HTA for English-language publications. Original studies published between January 1, 2000 and March 17, 2017 meeting the following criteria were included: adult population; study focus was CKD-related anemia; included results on patients receiving iron supplementation, red blood cell transfusion, or erythropoiesis stimulating agents (ESAs); reported results on HRQoL and/or costs. Studies which included patients with DD-CKD, did not directly compare different treatments, and had designs relevant to the objective were retained. HRQoL and cost outcomes, including healthcare resource utilization (HRU), were extracted and summarized in a narrative synthesis. Results: A total of 1,625 publications were retrieved, 15 of which met all inclusion criteria. All identified studies included ESAs as a treatment of interest. Two randomized controlled trials reported that ESA treatment improves HRQoL relative to placebo. Across eight studies comparing HRQoL of patients achieving high vs low hemoglobin (Hb) targets, aiming for higher Hb targets with ESAs generally led to modest HRQoL improvements. Two studies reported that ESA-treated patients had lower costs and HRU compared to untreated patients. One study found that aiming for higher vs lower Hb targets led to reduced HRU, while two other reported that this led to a reduction in cost-effectiveness. Limitations: Heterogeneity of study designs and outcomes; a meta-analysis could not be performed. Conclusions: ESA-treated patients undergoing dialysis incurred lower costs, lower HRU, and had better HRQoL relative to ESA-untreated patients. However, treatment to higher Hb targets led to modest HRQoL improvements compared to lower Hb targets.

RESUMO

PURPOSE: To compare post-operative recovery of prosthetic hip surgery patients with or without the implementation of iron supplementation with a new highly absorbable oral iron formulation. METHODS: Observational retrospective quality improvement assessment conducted on patients who had undergone elective prosthetic hip surgery (first implant) with ferritin < 100 mcg/dl and Hb values between 13 and 14 g/dl for men and 12 g/dl and 13.5 g/dl for women, or having ferritin levels > 100 mcg/dl but C-reactive protein (CRP) > 3 mg/l and transferrin saturation (TSAT) < 20%, which together are suggestive of functional iron deficiency. The analysis compared a group of non-anaemic patients having ferritin levels > 100 mcg/l to two groups of patients with iron deficiency, of which only one received iron supplementation. Measurements included haemoglobin levels, length of hospital stay, and number of transfused patients/blood units. RESULTS: Patients with iron deficiency supplemented with Sideral® Forte compared to non-supplemented patients showed a smaller decline in post-operative Hb (9.7 ± 1.24 g/dl vs 8.4 ± 0.6 g/dl), required shorter hospital stay (4 vs 6.5 days) and less blood transfusions (0 in the iron-supplemented group vs 7 units in the non-iron-supplemented group), yielding an overall savings of 1763.25 €/patient. CONCLUSIONS: Pre-operative sucrosomial iron supplementation at least 4 weeks prior to elective surgery in non-anaemic patients limits the drop in post-operative Hb levels, determining higher post-operative haemoglobin, quicker post-surgical recovery, shorter hospitalisation, and decreased surgery-related costs.

RESUMO

Background The Taiwan Health Insurance Bureau has conducted a bundled payment system for hemodialysis reimbursement since 1995. The maximum dose of erythropoiesis-stimulating agents allowed by insurance is capped at 20 000 U of epoetin or 100 µg of darbepoetin alfa per month. Nephrologists have avoided the use of high dosages of erythropoiesis-stimulating agents to achieve a hemoglobin level of 10 to 11 g/dL by iron supplementation. The clinical impact of these policies on patients' outcomes is unknown. The authors aimed to assess the AIM-HD (Association of Anemia, Iron parameters, and Mortality among the prevalent Hemodialysis patients) Study in Taiwan. Methods and Results The AIM-HD study was conducted based on the Taiwan Renal Registry Data System. From 2001 to 2008, the authors enrolled 42 230 patients undergoing hemodialysis who were older than 20 years and had received hemodialysis for more than 12 months. Patient follow-ups occurred until death or December 31, 2008. During a study period of 8 years, 12 653 (30.0%) patients died. After multivariate adjustment, the authors found that a hemoglobin level <10 g/dL was significantly associated with higher risk for all-cause and cardiovascular deaths. Moreover, a serum ferritin level between 300 and 800 ng/mL and transferrin saturation value between 30% and 50% were associated with the lowest all-cause mortality. Conclusions The authors recommend avoiding a low hemoglobin level and maintaining serum ferritin between 300 and 800 ng/mL and transferrin saturation between 30% and 50%, which were associated with lower risks of all-cause mortality among patients undergoing hemodialysis receiving the restricted erythropoiesis-stimulating agent doses but prompt intravenous iron supplementation in Taiwan.

RESUMO

BACKGROUND: Iron deficiency is a frequent complication of chronic kidney disease (CKD) that is associated with a decrease in the quality of life of patients and an increase in the risk of other clinical complications. Iron therapy represents one of the fundamentals of patients with CKD. Sucrosomial® oral iron allows Fisiogen Ferro Forte® to be used in all patients who are intolerant to treatment by the oral route of administration, or who present with malabsorption of conventional oral iron preparations. OBJECTIVE: The main objective of this study was to assess the economic impact of the oral iron Fisiogen Ferro Forte® for the management of iron deficiency in CKD patients in Spain. METHODS: A 4-year budget impact model was developed for the period 2017-2020 for CKD patients with iron deficiency who were candidates for intravenous iron due to a lack of response to oral iron, from the perspective of the Spanish healthcare system. Three subgroups of CKD patients were included in the analysis: predialysis, peritoneal dialysis, and post-transplant. The intravenous iron formulations Ferinject®, Venofer®, and Feriv® were considered appropriate comparators to be used in the model. National data on the prevalence of CKD for the three subgroups of patients were obtained from the literature, and input data on drug utilization and outpatient hospitalizations associated with iron administration were obtained by consulting nephrologists. Nephrology experts were also asked about resources used during medical visits and monitoring tests. Based on the unit costs for each iron therapy and the resources used, the total treatment cost per patient associated with each product was obtained to estimate the global budget impact of increasing the use of Fisiogen Ferro Forte®. RESULTS: The average annual budget savings due to an increase in Fisiogen Ferro Forte® and a decrease in intravenous iron have been estimated at €398,685, €180,937, and €195,842 over 4 years for the predialysis, peritoneal dialysis, and post-transplant groups, respectively. CONCLUSIONS: The increase in the use of Fisiogen Ferro Forte® leads to overall budget savings of €775,464 for the Spanish National Health Service over 4 years.

RESUMO

In order to inform large scale supplementation programme design, we review and summarize the barriers and enablers for improved coverage and utilization of iron and folic acid (IFA) supplements by pregnant women in 7 countries in Africa and Asia. Mixed methods were used to analyse IFA supplementation programmes in Afghanistan, Bangladesh, Indonesia, Ethiopia, Kenya, Nigeria, and Senegal based on formative research conducted in 2012-2013. Qualitative data from focus-group discussions and interviews with women and service providers were used for content analysis to elicit common themes on barriers and enablers at internal, external, and relational levels. Anaemia symptoms in pregnancy are well known among women and health care providers in all countries, yet many women do not feel personally at risk. Broad awareness and increased coverage of facility-based antenatal care (ANC) make it an efficient delivery channel for IFA; however, first trimester access to IFA is hindered by beliefs about when to first attend ANC and preferences for disclosing pregnancy status. Variable access and poor quality ANC services, including insufficient IFA supplies and inadequate counselling to encourage consumption, are barriers to both coverage and adherence. Community-based delivery of IFA and referral to ANC provides earlier and more frequent access and opportunities for follow-up. Improving ANC access and quality is needed to facilitate IFA supplementation during pregnancy. Community-based delivery and counselling can address problems of timely and continuous access to supplements. Renewed investment in training for service providers and effective behaviour change designs are urgently needed to achieve the desired impact.

RESUMO

The abatement of valproic acid sodium salt (VA) via photo-Fenton process was investigated to evaluate the effect of irradiation type. Three different light sources have been used: UVA (black light blue lamps, BLB reactor), UVC (UVC reactor) and simulated sunlight in a Solarbox (SB). Using the highest concentrations of Fe2+ (10mgL-1) and H2O2 (150mgL-1), 100% of VA degradation was observed in BLB and UVC devices, and 89.7% in Solarbox. Regarding mineralization, 67.4% and 76.4% of TOC conversion were achieved in BLB and UVC, respectively. In Solarbox, mineralization was negligible. Treated solutions under UVA or UVC radiation became biodegradable (BOD5/COD≥0.25), which was not observed in Solarbox where BOD5/COD achieved was only 0.20. Regarding to toxicity (Vibrio Fischeri method), all processes have promoted the overall toxicity reduction of VA solution. Transformation products were identified by a LC-ESI-TOF mass spectrometer, and degradation pathways were proposed. Operating costs and the energy needed by mg of VA removed were estimated and compared, for the different installations, showing that UVA can remove around 3 times more VA than SB and 2 times more VA than UVC, under the same conditions.

RESUMO

The utilization of Fenton's oxidation for the depuration of elderberry juice wastewater was studied. The aim was to select the adequate cost-effective operating conditions suitable to lead to an effluent within the legal thresholds to be discharged into the natural water courses. The treatment efficacy was assessed by chemical oxygen demand (COD), colour, phenolic content and total solids removal besides its ability to improve biodegradability (biochemical oxygen demand (BOD5)/COD). Moreover, the costs of the applied reactants were also considered. Fenton's reaction was able to abate at least 70% of COD (corresponding to a final value below 150 mg O2 L(-1)). Besides, total phenolic content degradation was always achieved. Within these conditions, the resulting effluent is able to be directly discharged into the natural hydric channels. Fenton oxidation could be successfully applied as a single treatment method with a reactant cost of 4.38 €â€…m(-3) ([Fe(2+)] = 20 mmol L(-1), [H2O2] = 100 mmol L(-1), pH = 3 and 4 h of oxidation procedure).

RESUMO

Iron deficiency anemia (IDA) continues to be very common worldwide. Intravenous (IV) iron is an infrequently used therapeutic option in children with IDA despite numerous studies in adults and several small but notable pediatric studies showing efficacy and safety. Presently, the availability of newer IV iron products allows for replacement of the total iron deficit at a single setting. These products appear safer compared to the high molecular weight iron dextrans of the past. Herein, we review the medical literature and suggest that front line use of IV iron should be strongly considered in diseases associated with IDA in children.

RESUMO

BACKGROUND: Patients with end-stage renal disease (ESRD) require phosphate binders for hyperphosphatemia and erythropoiesis-stimulating agents (ESAs) and intravenous (i.v.) iron for anemia. Ferric citrate (FC) is a novel, iron-based phosphate binder that increases iron stores and decreases i.v. iron and ESA usage while maintaining hemoglobin levels, and may decrease the cost of ESRD care. The study objectives were to (1) quantify differences in ESA and i.v. iron usage among ESRD patients receiving FC compared with active control (AC) (sevelamer carbonate and/or calcium acetate) on the basis of data from a 52-week phase III clinical trial and (2) standardize trial data to the general United States (US) ESRD population and calculate the potential impact of FC on ESRD cost/patient/year in the USA. STUDY DESIGN: The study was a randomized, controlled clinical trial. SETTING AND POPULATION: A total of 441 adult subjects with ESRD who received FC or AC for 52 weeks were included. MODEL, PERSPECTIVE, AND TIMELINE: Differences in ESA and i.v. iron usage between the treatment groups were modeled over time using generalized linear mixed models and zero-inflated Poisson models. Trends were modeled via logarithmic curves, and utilization patterns were applied to the general dialysis population to estimate expected resource savings. OUTCOMES: Study outcomes were costs saved/patient/year using FC versus AC (US dollars). RESULTS: Our model suggests an annual decrease of 129,106 U of ESAs and 1960 mg of i.v. iron per patient in the second year after a switch from AC to FC. Applying 2013 Medicare pricing, this would save $1585 in ESAs and $516 in i.v. iron: a total of $2101/patient/year; these savings would be expected to double for managed care plans. LIMITATIONS: The projections were made on 1 year of trial data. CONCLUSIONS: Phosphate binding with FC reduces i.v. iron and ESA usage. Given the high cost burden of ESRD, our model demonstrates significant potential cost savings. TRIAL REGISTRATION: ClinicalTrials.gov (NCT01191255) http://clinicaltrials.gov/ct2/show/NCT01191255 .

RESUMO

BACKGROUND: Absence of cost-effectiveness (CE) analyses limits the relevance of large-scale nutrition interventions in low-income countries. We analyzed if the effect of invitation to food supplementation early in pregnancy combined with multiple micronutrient supplements (MMS) on infant survival represented value for money compared to invitation to food supplementation at usual time in pregnancy combined with iron-folic acid. METHODS: Outcome data, infant mortality (IM) rates, came from MINIMat trial (Maternal and Infant Nutrition Interventions, Matlab, ISRCTN16581394). In MINIMat, women were randomized to early (E around 9 weeks of pregnancy) or usual invitation (U around 20 weeks) to food supplementation and daily doses of 30 mg, or 60 mg iron with 400 µgm of folic acid, or MMS with 15 micronutrients including 30 mg iron and 400 µgm of folic acid. In MINIMat, EMMS significantly reduced IM compared to UFe60F (U plus 60 mg iron 400 µgm Folic acid). We present incremental CE ratios for incrementing UFe60F to EMMS. Costing data came mainly from a published study. RESULTS: By incrementing UFe60F to EMMS, one extra IM could be averted at a cost of US$907 and US$797 for NGO run and government run CNCs, respectively, and at US$1024 for a hypothetical scenario of highest cost. These comparisons generated one extra life year (LY) saved at US$30, US$27, and US$34, respectively. CONCLUSIONS: Incrementing UFe60F to EMMS in pregnancy seems worthwhile from health economic and public health standpoints.

RESUMO

Ever since the introduction of EPO, ESAs and iron dosing have been driven by financial incentives. When ESAs were a profit center for providers, large doses were used. With ESAs becoming a cost center, a new trend has appeared, gradually replacing their use with iron to achieve the same therapeutic effect at lower cost. This financially driven approach, treating ESAs and iron as alternatives, is not consistent with human physiology where these agents act in a complementary manner. It is likely that we are still giving unnecessarily large doses of ESAs and iron, relative to what our patients' true needs are. Although we have highlighted the economic drivers of this outcome, many other factors play a role. These include our lack of understanding of the complex interplay of the anemia of chronic disease, inflammation, poor nutrition, blood loss through dialysis, ESAs and iron deficiency. We propose that physiology-driven modeling may provide some insight into the interactions between erythropoiesis and ferrokinetics. This insight can then be used to derive new, physiologically compatible dosing guidelines for ESAs and iron.
