Abstract
Rational use of drug involves the use of medicine as per clinical guidelines. Given the steady increase in the clinical utility of intravenous immunoglobulin (IVIG) either as licensed or off-label use, concerns are being raised about the possibility of supply shortages that could significantly impact patient care. Therefore, there is a need to regulate and to promote the rational use of this valuable medication. This cross-sectional chart review study attempts to evaluate the prescribing patterns of IVIG at two tertiary hospitals in Malaysia. Patients’ medical files and dispensing records were examined and compared with current guidelines. A total of 348 prescriptions for IVIG were written during the 1-year study period. The highest usage of IVIG was for neurological (47.9%), immunological (27.5%), and hematological conditions (20%). The number of prescriptions with the US Food and Drug Administration (FDA) licensed indications and off-label indications was 148 (42.5%) and 200 (57.5%), respectively. Age (OR: 1.02, 95% CI: 1.01–1.03, p = 0.003) and those admitted to the critical care units (OR: 11.11, 95% CI: 5.60–22.05, p < 0.001) were significant factors for receiving IVIG for an off-label indication. Most prescriptions (79%) had appropriate dosing. Significant factors associated with receiving inappropriate dose of IVIG include age (OR: 0.93, 95% CI: 0.89–0.97, p = 0.001) and those admitted to the critical care units (OR: 10.15, 95% CI: 3.81–27.06, p < 0.001). This study advocates the development and implementation of evidence-based clinical guidelines with prioritization protocol to ensure rational use of IVIG.

Abstract
Background Knowledge of gestational age is critical for guiding preterm neonatal care. In the last decade, metabolic gestational dating approaches emerged in response to a global health need; because in most of the developing world, accurate antenatal gestational age estimates are not feasible. These methods initially developed in North America have now been externally validated in two studies in developing countries, however, require shipment of samples at sub-zero temperature. Methods A subset of 330 pairs of heel prick dried blood spot samples were shipped on dry ice and in ambient temperature from field sites in Tanzania, Bangladesh and Pakistan to laboratory in Iowa (USA). We evaluated impact on recovery of analytes of shipment temperature, developed and evaluated models for predicting gestational age using a limited set of metabolic screening analytes after excluding 17 analytes that were impacted by shipment conditions of a total of 44 analytes. Results With the machine learning model using all the analytes, samples shipped in dry ice yielded a Root Mean Square Error (RMSE) of 1.19 weeks compared to 1.58 weeks for samples shipped in ambient temperature. Out of the 44 screening analytes, recovery of 17 analytes was significantly different between the two shipment methods and these were excluded from further machine learning model development. The final model, restricted to stable analytes provided a RMSE of 1.24 (95% confidence interval (CI) = 1.10-1.37) weeks for samples shipped on dry ice and RMSE of 1.28 (95% CI = 1.15-1.39) for samples shipped at ambient temperature. Analysis for discriminating preterm births (gestational age <37 weeks), yielded an area under curve (AUC) of 0.76 (95% CI = 0.71-0.81) for samples shipped on dry ice and AUC of 0.73 (95% CI = 0.67-0.78) for samples shipped in ambient temperature. Conclusions In this study, we demonstrate that machine learning algorithms developed using a sub-set of newborn screening analytes which are not sensitive to shipment at ambient temperature, can accurately provide estimates of gestational age comparable to those from published regression models from North America using all analytes. If validated in larger samples especially with more newborns <34 weeks, this technology could substantially facilitate implementation in LMICs.

Trends in IVIG use at a tertiary care Canadian center and impact of provincial use mitigation strategies: 10-year retrospective study with interrupted time series analysis. Transfusion 2019; 59:1988-1996. [PMID: 30916409 DOI: 10.1111/trf.15271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Revised: 12/16/2018] [Accepted: 02/22/2019] [Indexed: 11/26/2022]
Abstract
BACKGROUND Intravenous immunoglobulin (IVIG) is a fractionated plasma product used to treat a range of autoimmune or inflammatory conditions, as well as immunodeficiency. Demand for this high-cost product is increasing worldwide. Understanding historical changes in IVIG use is important for inventory management and demand forecasting as well as for the development of initiatives aimed at optimizing blood product use. STUDY DESIGN AND METHODS This was a 10-year retrospective cohort study of all patient encounters involving an IVIG transfusion from 2007 to 2016 at a four-site tertiary care hospital in Ontario, Canada. IVIG use was reported, including number of hospital encounters and amounts of IVIG prescribed. An interrupted time series analysis was performed to evaluate temporal changes in product use coinciding with the release of 2009-2010 provincial initiatives to optimize IVIG. RESULTS A total of 1,658,159.50 g of IVIG was administered from 2007 to 2016. Total annual volume administered initially decreased after implementation of new policies (-2032 g/quarter). The number of IVIG patient encounters also decreased (-49.8 encounters/quarter) but was mirrored by an increase in the total volume administered per patient encounter (+0.88 g/quarter). Use increased 820 g/quarter from 2013 to 2016 but was 21% lower than projected before implementation of provincial policies. CONCLUSION Trends in IVIG use show ongoing increases in the number of patients treated with the product. Development and implementation of provincial initiatives to optimize IVIG use coincided with significant short-term changes at a large tertiary care hospital. Novel initiatives aimed at dose minimization and prescription rationalization for this therapy are needed on local as well as larger scales.

Abstract
BACKGROUND Prophylactic immunoglobulin has been used with varying efficacy to reduce complications in hematopoietic stem cell transplant recipients. STUDY DESIGN AND METHODS A systematic review and meta-analysis was conducted of randomized controlled trials that assessed clinical outcomes (overall survival, transplant-related mortality, graft-versus-host disease [GVHD], veno-occlusive disease [VOD], interstitial pneumonitis, disease relapse, cytomegalovirus [CMV] infection and disease, non-CMV infection) of immunoglobulin prophylaxis versus placebo in hematopoietic stem cell transplant recipients. MEDLINE, EMBASE, EBM Reviews, and the Cochrane Central Register of Controlled Trials were searched up to June 2017. Quality of included studies and outcomes were evaluated via Risk of Bias assessment and Grading of Recommendations, Assessment, Development and Evaluation criteria, respectively. RESULTS Of 899 citations screened, 27 studies (n = 3934) were included. Immunoglobulin prophylaxis had no impact on survival (risk ratio [RR], 0.94; 95% confidence interval [CI], 0.88-1.01; 11 studies, n = 1962) but decreased risk of acute GVHD (RR, 0.78; 95% CI, 0.65-0.94; eight studies, n = 1097) and CMV disease (RR, 0.52; 95% CI, 0.28-0.97; two studies, n = 167). Meta-analysis revealed increased risk of VOD (RR, 3.04; 95% CI, 1.10-8.41; three studies, n = 384) and disease relapse (RR, 1.26; 95% CI, 1.07-1.49; seven studies, n = 1647). Other outcomes were small in sample size or nonsignificant. Results should be interpreted cautiously given the low quality of studies and evidence of outcomes. CONCLUSION Immunoglobulin prophylaxis did not have a significant effect on survival. Positive clinical effects were shown for acute GVHD and CMV disease and negative effects against VOD and disease relapse. No studies examined the effect of immunoglobulin treatment in hypogammaglobulinemic patients despite current guidelines, warranting further studies in this population.

Impact of organizational interventions on reducing inappropriate intravenous immunoglobulin (IVIG) usage: A systematic review and meta-analysis. Transfus Apher Sci 2018; 57:215-221. [PMID: 29439921 DOI: 10.1016/j.transci.2018.01.008] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2017] [Revised: 01/21/2018] [Accepted: 01/23/2018] [Indexed: 01/23/2023]
Abstract
BACKGROUND With increasing global use of intravenous immunoglobulin (IVIG), there is interest in its appropriate usage. Efforts to regulate IVIG usage have primarily taken the form of organizational interventions implemented in hospitals to monitor and improve physician prescribing. Similar interventions have proven effective in reducing the inappropriate and total hospital usage of other blood products, but their efficacy on IVIG use is less understood. Thus, we performed a systematic review of studies reporting the change in inappropriate IVIG use following such interventions in hospitals or regions. METHODS A systematic search was carried out using MEDLINE and EMBASE (1966-June 2016) for English language studies if they 1) were primary research, 2) described an organizational intervention to target plasma, IVIG, or albumin, and 3) reported appropriateness of usage and total usage preand post-intervention. Review Manager v5.0 was utilized to perform a random-effects meta-analysis on eligible IVIG studies, where the risk ratio (RR) of inappropriate IVIG transfusion comparing pre- and postintervention periods was calculated with 95% confidence intervals (CI). RESULTS Our search retrieved three retrospective cohort studies, where metaanalysis encompassing 2100 episodes of IVIG transfusion demonstrated no decrease in inappropriate IVIG use (RR 1.55, 95% CI 0.78-3.07). Heterogeneity between studies was considerable (I2 = 89%). CONCLUSION Organizational interventions were ineffective at changing inappropriate IVIG use, but more high-quality studies describing the effects of these interventions are required before any conclusions can be drawn. Futureresearch efforts should also be directed at evolving evidence-based IVIGguidelines to improve patient safety and burdens on healthcare systems.

Abstract
Objective: The dramatic increase in the consumption of intravenous immunoglobulin (IVIG) products in nonapproved indications, its high cost, and the severe shortage has developed the concerns of its irrational utilization, especially in the Middle East countries. Therefore, this clinical study attempts to describe the pattern of IVIG administration in one of the largest hospitals in Iran and find the variables associated with inappropriate IVIG utilization. Methods: This cross-sectional medication utilization study was conducted in one of the largest referral hospitals in Iran. Random IVIG administrations were assessed from different wards for 9 months. Different data were collected to evaluate the pattern of IVIG administration and find variables, which could predict this behavior. Findings: IVIG was prescribed for approved indications in 72% of 201 patients recruited in our study. Although, the rate of drug administration was appropriate in most of the study population, hydration and pre-medication were unsuitable in more than one-third of the patients. Among the variables analyzed to find the factors affecting the misuse of IVIG, female gender, older age of patients, and longer time to start IVIG administration due to hospital admission were statistically significant in the multivariate model. Conclusion: Despite the fact that inappropriate use of IVIG was confirmed in less than 30 % of its utilization for the studied patients, it caused a potential risk of treatment complications and a notable and unjustifiable burden of unnecessary costs for this University hospital.

Abstract
OBJECTIVE Retrospective audit of IVIG Request Forms in four Ontario tertiary care centres: to determine the case mix of new IVIG requests, to authenticate information provided, and to determine documentation of clinical efficacy. AIMS To understand contributors to increases in IVIG utilisation and to determine whether IVIG is being used and monitored appropriately. INTRODUCTION Intravenous immunoglobulin (IVIG) use in Canada is high compared with other developed countries. We performed a retrospective audit of new IVIG Request Forms across four tertiary care centres in Ontario, one with an active surveillance programme, to determine the case mix, authenticate information provided and assess documentation of efficacy. METHODS Consecutive adult patients with a first-time IVIG request in 2014 were included. The ordering physician specialty, form completeness, documentation of diagnostic criteria for the medical condition and indication for IVIG use and documentation of efficacy were assessed by form and chart review. RESULTS Of 178 patients, the most common indications for IVIG were immune thrombocytopenia (24.2%) and secondary immune deficiency (20.2%). The most frequent prescribers were haematologists (37.6%) and neurologists (10.7%). Other conditions not listed on the form represented 24.2% of cases, with most not indicated in current guidelines. A total of 32.6% of cases overall lacked verification of diagnostic criteria and 51.7% lacked verification for IVIG utilisation criteria, with the number of cases meeting criteria based on documentation being higher at the active surveillance site (P = 0.005). A total of 19.1% of cases had a discrepancy between the indication written on the form and the documented clinical diagnosis. A total of 18.7% of clinic notes following IVIG had no mention of efficacy. CONCLUSION Our audit demonstrates a lack of compliance with IVIG Request Form requirements, a lack of documentation of diagnostic criteria and efficacy, and suggests inappropriate use of IVIG. Current implementation of the form may not be sufficient as a strategy for improving appropriate IVIG use.

Abstract
AIM Intravenous immunoglobulin (IVIG) is an expensive therapy used in immunodeficiency and autoimmune disorders. Increasing demands and consequent shortages result in a need for usage to conform to guidelines. METHOD We retrospectively evaluated IVIG use for neuroimmunological indications and adherence to existing guidelines in a major Australian paediatric hospital between 2000 and 2014. RESULTS One-hundred and ninety-six children (96 male, 100 female; mean age at disease onset 6y 5mo [range 3mo-15y 10mo], mean age at first IVIG dose 7y 2mo [range 3mo-16y 5mo]) received IVIG for neuroimmunological indications during the study period (28.1% had Guillain-Barré syndrome), representing 15.5% of all hospital indications. In total, 1669 IVIG courses were administered (total 57 221g, median 78g/patient, range 12-5748g). The highest median numbers of courses were in chronic inflammatory demyelinating polyneuropathies, opsoclonus-myoclonus ataxia syndrome, suspected immune-mediated epilepsies, and Rasmussen's encephalitis. Adverse reactions occurred in 25.5% of patients, but these were mostly minor. Outcome at follow-up was best in anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis, Guillain-Barré syndrome, and myasthenia gravis, and worst in Rasmussen's encephalitis and epilepsies. The total cost of IVIG was US$2 595 907 (median $3538/patient, range $544-260 766). Of patients receiving IVIG, 45.4% to 57.1% were given the therapy for 'weak' indications or indications 'not listed' in international guidelines. Some entities commonly treated with IVIG in current practice, such as anti-NMDAR encephalitis and transverse myelitis, are not listed in most guidelines. INTERPRETATION Our study demonstrates that IVIG is generally well tolerated but expensive, and discloses discrepancies between guidelines and clinical practice in paediatric neurology, suggesting both the need for greater adherence to current recommendations, and for recommendations to be updated to accommodate emerging indications.

Transfusion 2016; 56:2704-2711.

Abstract
BACKGROUND Intravenous immunoglobulin (IVIG) is used to treat a variety of diseases in the neonatal intensive care unit (NICU). Although audits have reported on the spectrum of IVIG use in adults, the indications and utilization in neonates has not been investigated. The objectives of this study were to describe the usage pattern of and indications for IVIG in a tertiary care NICU. STUDY DESIGN AND METHODS A retrospective chart review was performed of all neonates who received IVIG in the NICU from January 2003 to December 2013. Data collected included patient demographic features, antenatal maternal details, neonatal laboratory results, treatment details, adverse events, and patient outcome. RESULTS Thirty-seven neonates received IVIG over the 11-year period. Twenty-three (67%) were treated for hemolytic disease of the newborn (HDN); 13 treatments were ABO related, six were anti-D related, and four were for clinically significant antibodies. Fourteen (33%) were treated for non-HDN causes, including eight for septic neonates, two for neonates with necrotizing enterocolitis, two for neonates with a clinically significant antibody but without evidence of hemolysis, and two for neonates with glucose 6-phosphate dehydrogenase deficiency. A complete hemolytic workup was not performed consistently before the receipt of IVIG. CONCLUSIONS This novel assessment of IVIG use in the NICU revealed the spectrum of disease for which IVIG is ordered. This study also found that key diagnostic tests needed to confirm an immune etiology for idiopathic jaundice are not performed routinely before IVIG receipt. Neonatal transfusion-related databases are needed to carry out pragmatic clinical trials to establish better evidence-based guidelines for IVIG therapy in the NICU.

Abstract
INTRODUCTION Haematopoietic stem cell transplantation (HSCT) is commonly employed in the management of haematological malignancies. This intervention results in an increased risk of infectious and immune-related complications. Prophylactic immunoglobulin therapy has been used to prevent post-HSCT complications, including infections, with varying efficacy. We sought to update the current evidence supporting the use of immunoglobulins in the modern HSCT era. METHODS/ANALYSIS Using a structured search strategy, we will perform a systematic review of the literature from MEDLINE, EMBASE and all EBM Reviews databases. We will include randomised clinical trials investigating clinical outcomes of prophylactic polyvalent immunoglobulin or cytomegalovirus (CMV)-specific immunoglobulin or plasma in patients undergoing HSCT. Clinical outcomes will include overall survival, transplant-related mortality, CMV infection, CMV disease, graft-versus-host disease, interstitial pneumonitis/fibrosis and hepatic veno-occlusive disease. Studies that only reported the results of biochemical tests will be excluded. Data will be extracted by two investigators independently. Study quality assessment will be evaluated using a validated five-point system as proposed by Jadad. Trial quality will be further assessed by identifying whether there was adequate allocation concealment. Where appropriate, a meta-analysis will be performed where relative risk will be used as the primary summary measure with 95% CIs. Pooled measures will be calculated for randomised clinical trials using a random-effects model. The Cochrane Q/χ(2) test and I(2) statistic will also be calculated to evaluate heterogeneity. We will also use a visual inspection of a funnel plot to assess potential publication bias. DISCUSSION This systematic review aims to provide current evidence to justify the use of immunoglobulin prophylaxis in HSCT recipients. We will discuss whether current HSCT guidelines are supported by the current evidence, and whether further trials are needed, given the changing landscape of patients undergoing HSCT and the immunoglobulin manufacturing process. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42015016684.

Abstract
Intravenous immunoglobulin (IVIg) therapy has multiple mechanisms of immunomodulatory action. We wished therefore to assess its efficacy in a spectrum of patients with refractory uveitis. Retrospective review of clinical charts was conducted to document response to IVIg treatment in consecutive patients with treatment-refractory uveitis. Main outcome measures were control of intraocular inflammation, visual acuity, progression of the disease, and complications. Four (two male) patients, with a mean age at the beginning of the treatment of 47 years (range: 39-64), were included in the study. Indication for treatment was patients with active non-infectious uveitis refractory to steroids and immunomodulatory therapy. All patients received a course of 0.5 g/kg per day of IVIg for three consecutive days, repeating this course at a mean of 11 week (range: 2-39 weeks) intervals when indicated clinically. The median duration of the IVIg therapy was 7 months (range: 3-14 months). In three patients treatment resulted in stabilisation and prevention of progression of the disease, and additionally in two patients it facilitated a decrease in prednisolone dose. Treatment failed to induce long-term remission in one patient with recurrence of macular oedema. IVIg was well tolerated with neither immediate nor longer-term adverse events observed. In three out of four cases IVIg was an effective adjunctive therapy and well tolerated for the management of treatment-refractory uveitis.

Abstract
BACKGROUND Intravenous immune globulin (IVIG) is an expensive and sometimes scarce blood product that carries some risk. It may often be used inappropriately. We evaluated the appropriateness of IVIG use before and after the introduction of an utilization control program to reduce inappropriate use. METHODS We used the RAND/UCLA Appropriateness Method to measure the appropriateness of IVIG use in the province of British Columbia (BC) in 2001 and 2003, before and after the introduction of a utilization control program designed to reduce inappropriate use. For comparison, we measured the appropriateness of use during the same periods in the province of Alberta, which had no control program. RESULTS Of 2256 instances of IVIG use, 54.1% were deemed to be appropriate, 17.4% were of uncertain benefit, and 28.5% were deemed inappropriate. The frequency of inappropriate use in BC after the introduction of the utilization control program did not differ significantly from the frequency before the program or the frequency in Alberta. INTERPRETATION Almost half of IVIG use in BC and Alberta was judged to be inappropriate or of uncertain benefit, and the frequency of inappropriate use did not decrease after implementation of a utilization control program in BC. More effective utilization controls are necessary to prevent wasted resources and unnecessary risk to patients.
