Cost of severe hypoglycaemia in nine European countries

Objective: Complications contribute largely to the economic gravity of diabetes mellitus (DM). How they arise and are treated differs substantially between countries. This paper assesses the total annual, direct, and indirect cost of severe hypoglycemia events (SHEs) in nine European countries: Bulgaria, Croatia, the Czech Republic, Greece, Hungary, Macedonia/the former Yugoslav Republic of Macedonia (MK), Poland, Slovenia, and Spain.

Methods: Data was collected on epidemiology, treatment structure, SHE-driven resource consumption, and unit costs. Two systematic reviews—on the SHE rates and the resources used for treatment—and data on the days-of-work lost due to SHE along with salaries and employment rates were used. The total SHE cost in each country was calculated and how the differences are driven by individual parameters was analysed.

Results: The annual costs of SHEs varied in absolute terms from €379,951.25 in MK up to €58,429,684.40 in Spain, or—when expressed per one drug-treated DM patient—from €5.47 in Bulgaria up to €17.74 in Spain. Indirect cost constituted between 6.01% (MK) and 26.49% (Hungary) of the total cost. The differences between countries are driven mostly by the cost of treating a single event, and this is related to general differences in prices.

Limitations: The main limitation is the lack of good quality data in some parts, and the necessity to use mean-value imputations, experts’ opinions, etc. Additionally, we only considered DM treatment as the SHE driver, while other elements, e.g. style of living, may contribute substantially.

Conclusions: A common framework can be applied to estimate the economic burden of SHE in various countries, allowing one to identify the drivers of differences in cost. Treating DM is complex, and so no resolute conclusions ought to be drawn as to whether SHE management is better in one country than another.     

Cost effectiveness of memantine in Alzheimer's disease in the UK

Objective: This analysis assesses the cost-effectiveness of memantine for the treatment of moderate-to-severe Alzheimer's disease (AD) in the UK.

Methods: This cost-utility analysis was based on a Markov model. The model simulated 5-year progress of patients with AD until they need full-time care (FTC), defined as a patient becoming either dependent or institutionalised. Transition probabilities were based on a predictive equation, derived from the London and South-East Region epidemiological study. Resource use, utilities and mortality were obtained from the same study. Memantine efficacy was based on a meta-analysis of six large trials. The model compared memantine to its alternative in the UK, i.e. no pharmacological treatment or background therapy with acetylcholinesterase inhibitors.

Results: Memantine was found to delay the need to FTC by 6 weeks compared with current practice in the UK. It was associated with increased quality-adjusted life-years and cost savings to the healthcare system (probability of this outcome was 96%). The projections were made assuming that benefits from the 6-month treatment were sustained over time, which is regarded as the main limitation. The model underwent extensive sensitivity analyses, which confirmed the base-case findings.

Conclusions: The model suggests that memantine delays the need for FTC and decreases cost. It can be regarded as a cost-effective choice in the management of moderate and severe AD.

The economic burden of uncontrolled gout: how controlling gout reduces cost

Aim: To evaluate the burden of uncontrolled gout by examining estimated costs and cost drivers.

Materials and methods: Data from the 2012 and 2013?US National Health and Wellness Survey (NHWS; 2012 NHWS, n?=?71,157 and 2013 NHWS, n?=?75,000) were utilized in this study. Based on self-reported gout diagnosis and gout symptoms, respondents were categorized into three groups: controlled gout (n?=?344), uncontrolled gout (n?=?2,215), and non-gout controls (n?=?126,360). Chi-square tests and one-way analysis of variance (ANOVAs) were used to assess group differences on work productivity loss, healthcare resource utilization, and costs. Zero-inflated negative binomial regressions were used to assess the burden of uncontrolled gout on total costs after controlling for covariates.

Results: Patients with uncontrolled gout had higher presenteeism, overall work impairment, activity impairment, and number of emergency department visits than those with controlled gout or controls. Overall, uncontrolled gout patients had both higher indirect and total costs compared to patients with controlled gout. After controlling for confounders, those with uncontrolled gout had higher total costs than controlled gout respondents and non-gout controls; there was no significant difference in total costs between patients with controlled gout and non-gout controls.

Limitations: Results were based on cross-sectional, self-reported data, making causal inferences more uncertain. Additionally, sample size was small for controlled-gout respondents. Lastly, sampling weights were not used, thus potentially limiting generalizability.

Conclusion: Gout can be an expensive condition, particularly if it is not properly controlled. This study provides support that controlling symptoms (e.g. flares) can reduce the economic and societal burden of gout. Therefore, more attention needs to be paid to effective management of gout symptoms.

Changes in healthcare resource use and costs associated with early versus delayed initiation of atypical antipsychotic adjunctive treatment in major depressive disorder

Aims: The study compared all-cause and major depressive disorder (MDD)-related healthcare resource use (HRU) and costs in patients with MDD treated with atypical antipsychotic (AAP) adjunctive therapy early or later in treatment.

Materials and methods: Adults with MDD and antidepressant treatment (ADT) who newly initiated adjunctive aripiprazole, brexpiprazole, lurasidone, or quetiapine between October 1, 2014 and September 30, 2015 were identified in the IQVIA Real-World Data Adjudicated Claims database; the index date was the date of the first AAP claim. Patients were stratified into three cohorts: AAP initiated in the first year (Y1); in the second year (Y2); and more than 2 years (Y3) of first ADT use. Within each cohort, HRU and costs were compared between the 12 months before and after the index date. Pre–post changes in HRU and costs were then compared between cohorts.

Results: Five hundred and six (36.7%) patients were categorized as Y1; 252 (18.3%) as Y2; and 622 (45.1%) as Y3. AAP use was associated with significantly decreased rates of all-cause and MDD-related hospitalization and emergency department visits, and increased rates of pharmacy fills and physician office visits; and the magnitude of changes was largest in cohort Y1. Cohort Y1 had the largest reductions in mean (±SD) all-cause medical costs per patient (?$10,496?±?$85,022, p?=?.015) compared to Y2 (?$2,474?±?$85,022, p?=?.572) and Y3 (?$472?±?$31,334, p?=?.823), mainly due to the reduction in hospitalization. After adjusting for differences in baseline characteristics, the largest reductions in hospitalization and medical costs were observed in cohort Y1. Similar increases in all-cause pharmacy costs were seen in all cohorts. A similar trend in costs was observed in MDD-related healthcare services.

Limitations and conclusions: AAP treatment was associated with reductions in all-cause and MDD-related medical costs, primarily in decreased hospitalization. The reductions were largest among patients who initiated treatment in the first year.     

Burden of illness associated with sinusoidal obstruction syndrome/veno-occlusive disease in patients with hematopoietic stem cell transplantation

Aims: Sinusoidal obstruction syndrome (SOS) is a life-threatening complication of hematopoietic stem cell transplantation (HSCT) associated with significant morbidity and mortality. Healthcare utilization, costs, and mortality were assessed in HSCT patients diagnosed with SOS, with and without multi-organ dysfunction (MOD).

Materials and methods: This retrospective observational study identified real-world patients undergoing HSCT between January 1, 2009 and May 31, 2014 using the Premier Healthcare Database. In absence of a formal ICD-9-CM diagnostic code, SOS patients were identified using a pre-specified definition adapted from Baltimore and Seattle criteria and clinical practice. Severe SOS (SOS/MOD) and non-severe SOS (SOS/no-MOD) were classified according to clinical evidence for MOD in the database.

Results: Of the 5,418 patients with a discharge diagnosis of HSCT, 291 had SOS, with 134 categorized as SOS/MOD and 157 as SOS/no-MOD. The remaining 5,127 patients had HSCT without SOS. Overall SOS incidence was 5.4%, with 46% having evidence of MOD. Distribution of age, gender, and race were similar between the SOS cohorts and non-SOS patients. After controlling for hospital profile and admission characteristics, demographics, and clinical characteristics, the adjusted mean LOS was 31.0 days in SOS/MOD compared to 23.9 days in the non-SOS cohort (medians?=?26.9 days vs 20.8 days, p?p?Limitations: Limitations of retrospective observational studies apply, since the study was not randomized. Definition for SOS was based on ICD-9 diagnosis codes from a hospital administrative database and reliant on completeness and accuracy of coding.

Conclusions: Analysis of real-world data shows that SOS/MOD is associated with significant increases in healthcare utilization, costs, and inpatient mortality.     

Hospital-based inpatient resource utilization associated with autosomal dominant polycystic kidney disease in the US

Abstract

Objective:

Polycystic kidney disease (PKD) is a clinically and genetically heterogeneous class of genetic disorders characterized by development of renal cysts leading to renal failure and end stage renal disease (ESRD). Autosomal dominant polycystic kidney disease (ADPKD) accounts for the majority of PKD cases and is the predominant monogenic cause of ESRD. Limited information on patient characteristics and healthcare resource utilization is available in this population. This study assessed hospital-based inpatient utilization of patients with ADPKD in the US to help further understand the disease, which may lead to treatments that delay progression and reduce healthcare resource utilization.

Methods:

A cross-sectional analysis was conducted using MedAssets Health System Data to investigate inpatient resource utilization for a total of 1876 patients hospitalized with ADPKD or chronic kidney disease (CKD). Patient characteristics and inpatient resource utilization were compared between hospitalized patients with ADPKD and CKD, including demographic and clinical characteristics, overall health, rates of complications and surgical interventions, and average length of hospital and intensive care unit stay.

Results:

Compared with patients with CKD, patients with ADPKD were more likely to have commercial insurance as their primary payer (36.1 vs 17.8%) and were significantly younger (mean age 57.9 vs 69.5 years) and generally healthier (Charlson Comorbidity Score of 2.0 vs 3.3). Patients with ADPKD also had a substantially shorter average length of hospital stay (6.3 vs 10.3 days). However, patients with ADPKD experienced more kidney-related complications and a higher surgical procedure rate (mainly for transplant and complete nephrectomy).

Conclusions:

Although patients with ADPKD were generally healthier than patients with CKD, specific kidney function complications were more frequent. Patients with ADPKD had a higher rate of major kidney procedures, which may contribute to the high burden of ADPKD-related hospital-based inpatient resource utilization.     

Cost of stroke in Canada: a 1-year prospective study

Summary

The objective of this study was to estimate the 1-year cost of stroke for patients in Canada in 2004 and to determine the factors that contribute to this cost.

This work was based on a prospective follow-up study of all patients presenting with a stroke or transient ischaemic attack (TIA) to the emergency room in a large teaching hospital over a 6-month prospective period. All healthcare, social services, patient and caregiver resource utilisation attributable to strokes or TIAs were included in the analysis. There were 365 patients who met the

inclusion criteria. The average 1-year cost of managing patients with TIA was the lowest at $17,769, followed by ischaemic strokes at $53,576 and haemorrhagic strokes at $56,573. Predictors for 1-year cost were: type of stroke; discharge severity of stroke; death; marital status; discharge destination; and the presence of diabetes and congestive heart failure.

Initial hospitalisation costs represented the majority of 1-year costs of stroke. However, caregiver expenses are significant at between 11% and 27% of the total are 1-year cost.

Real-world comparison of hospitalization costs for heart failure in type 2 diabetes mellitus patients with established cardiovascular disease treated with canagliflozin versus other antihyperglycemic agents

Abstract

Aims: This real-world study compared hospitalization for heart failure (HHF) costs and all-cause healthcare costs in patients with type 2 diabetes mellitus (T2DM) and established cardiovascular disease treated with the sodium glucose co-transporter 2 inhibitor (SGLT2i) canagliflozin and non-SGLT2i antihyperglycemic agents (AHAs).

Materials and methods: Propensity score-matched cohorts from a retrospective observational study (OBSERVE-4D) using the Truven MarketScan Commercial Claims and Encounters and Optum Clinformatics databases were analyzed. HHF and all-cause healthcare costs per-patient-per-month (PPPM) were compared for patients initiated on canagliflozin and non-SGLT2i AHAs in the on-treatment analysis.

Results: Baseline characteristics were well balanced between matched cohorts that included new users of canagliflozin or non-SGLT2i AHAs in the Truven (13,954 and 45,101, respectively) and Optum (11,490 and 53,360, respectively) databases. The mean (95% CI) PPPM cost of HHF was lower for canagliflozin than for non-SGLT2i AHAs in analyses of both the Truven ($21.31 [$21.25, $21.37]) and Optum ($30.43 [$30.41, $30.45]) databases. The mean (95% CI) PPPM all-cause healthcare cost was also lower for canagliflozin than for non-SGLT2i AHAs in analyses of both the Truven ($321 [$280, $361]) and Optum ($449 [$402, $495]) databases.

Limitations: This study is subject to the limitations inherent to observational research including potential for coding errors and biases and unobserved confounding. Because all patients were in commercially administered health plans, these findings cannot be easily generalized to uninsured or Medicaid populations. Patient costs were evaluated up to and including their first HHF event. Post-discharge costs such as the costs of subsequent rehospitalizations were not included in this analysis.

Conclusions: For patients with T2DM and established cardiovascular disease in this real-world study, treatment with canagliflozin was associated with lower HHF costs and all-cause healthcare costs compared with treatment with non-SGLT2i AHAs.

Cost effectiveness of palivizumab in children with congenital heart disease in Germany

Abstract

Objectives: To assess the cost effectiveness of palivizumab, a humanised monoclonal antibody, used as prevention against severe respiratory syncytial virus (RSV) infection requiring hospitalisation, in infants with haemodynamically significant congenital heart disease (CHD) in the German healthcare setting.

Study design: A decision-tree model was used to estimate the cost effectiveness of palivizumab for a hypothetical cohort of patients. The analysis was based on a lifetime follow-up period in order to capture the impact of palivizumab on long-term morbidity and mortality resulting from an RSV infection. Data sources included published literature, the palivizumab pivotal trials, official price/tariff lists and national population statistics. The study was conducted from the perspective of society (primary analysis) and the healthcare purchaser (secondary analysis).

Results: From the societal perspective, use of palivizumab results in an incremental cost-effectiveness ratio (ICER) of €2,615 per quality-adjusted life-year (QALY) without discounting, which increases to €9,529/QALY after discounting. From the perspective of the German healthcare purchaser, use of palivizumab results in an ICER of €4,576/QALY without discounting, which increases to €16,673/QALY after discounting. Probabilistic sensitivity analyses confirmed the robustness of the model. The study is limited by a number of conservative assumptions. It was assumed that palivizumab only affects the occurrence of RSV hospitalisation and does not influence the severity of the RSV infection. Another assumption was that international clinical trial data and data on utilities could be applied to the German healthcare setting.

Conclusion: This analysis showed that palivizumab represents a cost-effective means of prophylaxis against severe RSV infection requiring hospitalisation in infants with haemodynamically significant CHD.     

Evaluating medical resource utilization and costs associated with thrombocytopenia in chronic liver disease patients

Abstract

Objective:

Thrombocytopenia (TCP), defined as platelet counts <150,000/µL, is a common complication of severe chronic liver disease (CLD). This retrospective study estimated the prevalence of thrombocytopenia in a large population of CLD patients and compared medical resource utilization and medical care costs by TCP status.

Methods:

A retrospective analysis was conducted on a longitudinal administrative claims database from a large US commercial health plan. Patients assigned CLD diagnosis codes from January 1, 2000–December 31, 2003 were identified; annual ambulatory visits, ER visits, inpatient stays, and general and CLD-related medical care costs for patients with vs without TCP (identified using diagnosis codes and platelet count data if available) were compared.

Results:

Of 56,445 patients with an ICD-9-CM diagnosis for CLD, 1289 (2.3%) had a diagnosis for TCP. CLD patients with vs without a TCP diagnosis had >2.5-times the annual number of liver disease-related ambulatory visits (3.6 vs 1.4; odds ratio [OR]?=?2.6, p?<?0.01); were 13-times more likely to have a liver-related inpatient stay (OR?=?13.0, p?<?0.01); were nearly 4-times more likely to have a liver-related ER visit (OR?=?3.9, p?<?0.01); had 3.5-fold greater mean annual overall medical care costs ($43,560 vs $12,270, p?<?0.01); and had 7-fold greater annual liver disease-related medical care costs ($9940 vs $1420, p?<?0.01). Similar results were seen for patients with platelet count data indicating TCP.

Limitations:

CLD and TCP are not always diagnosed, nor is diagnosis uniform or standardized; administrative claims data are subject to coding errors, and individuals covered are not necessarily representative of the general US population. The number of CLD patients in this study with TCP (n?=?1289) is small relative to that expected in the general US population.

Conclusions:

In this analysis, CLD patients with TCP used significantly more medical resources and incurred significantly higher medical care costs than those without TCP.     

Modeling the fiscal costs and benefits of alternative treatment strategies in the United Kingdom for chronic hepatitis C

Background: Hepatitis C (HCV) infection causes substantial direct health costs, but also impacts broader societal and governmental costs, such as tax revenue and social protection benefits. This study investigated the broader fiscal costs and benefits of curative interventions for chronic Hepatitis C (CHC) that allow individuals to avoid long-term HCV attributed health conditions.

Methods: A prospective cohort model, assessing the long-term fiscal consequences of policy decisions, was developed for HCV infected individuals, following the generational accounting analytic framework that combines age-specific lifetime gross taxes paid and governmental transfers received (i.e. healthcare and social support costs). The analysis assessed the burden of a theoretical cohort of untreated HCV infected patients with the alternative of treating these patients with a highly efficacious curative intervention (ledipasvir/sofosbuvir [LDV/SOF]). It also compared treating patients at all fibrosis stages (Stages F0–F4) compared to late treatment (Stage F4).

Results: Based on projected lifetime work activity and taxes paid, the treated cohort paid an additional £5,900 per patient compared to the untreated cohort. Lifetime government disability costs of £97,555 and £125,359 per patient for treated cohort vs no treatment cohort were estimated, respectively. Lifetime direct healthcare costs in the treated cohort were £32,235, compared to non-treated cohort of £26,424, with an incremental healthcare costs increase of £5,901 per patient. The benefit cost ratio (BCR) of total government benefits and savings relative to government treatment costs (including LDV/SOF) ranged from 1.8–5.6. Treating patients early resulted in 77% less disability costs, 43% lower healthcare costs, and 33% higher tax revenue.

Conclusion: The ability to cure Hepatitis C offers considerable fiscal benefits beyond direct medical costs and savings attributed to reduced disability costs, public allowances, and improved tax revenue. Changes in parameters, such as productivity, wage growth, and tax rates, can influence the conclusions described here.     

The burden associated with thrombocytopenia and platelet transfusions among patients with chronic liver disease

Abstract

Background: Thrombocytopenia (TCP), a common complication of chronic liver disease (CLD), can cause uncontrolled bleeding during procedures. As such, CLD patients with TCP and platelet counts <50,000/μL often receive prophylactic platelet transfusions before invasive procedures. However, platelet transfusions are associated with clinical complications, which may result in increased healthcare utilization and costs.

Objective: This retrospective database analysis describes the clinical and economic burden in CLD patients with TCP, CLD patients without TCP, and CLD patients with TCP who receive platelet transfusions.

Methods: Adult CLD patients with or without TCP were identified in the IBM MarketScan Commercial Claims and Medicare Supplemental data from 1 January 2012 to 31 December 2015. CLD patients with or without TCP were propensity-score matched (1:1) for the analysis of annual healthcare utilization and costs. Platelet transfusions among CLD patients with TCP were identified using procedure codes.

Results: Of the 601,626 patients with CLD, 8,292 (1.4%) patients with TCP were matched to patients without TCP. Among CLD patients with TCP, 981 (11.8%) patients received ≥1 platelet transfusions and met inclusion/exclusion criteria. Compared to patients without TCP, CLD patients with TCP had more complications, including higher prevalence of neutropenia (11.4% vs 2.9%) and bleeding events (21.4% vs 10.9%), greater resource utilization including greater average hospital admissions (1.2 vs 0.7, p?<?.01), greater average ER visits (2.1 vs 1.3, p?<?.01), higher average outpatient office visits (20.1 vs 18.4, p?<?.01), and higher average healthcare costs including total costs (p?<?.01), inpatient costs (p?<?.01), ER visit costs (p?<?.01), and outpatient office visit costs (p?<?.01). The mean annual total costs in CLD and TCP patients with platelet transfusions were $206,396.

Conclusions: CLD patients with TCP, and particularly those who received platelet transfusions, experienced significantly greater clinical and economic burden compared to CLD patients without TCP. Safer and more cost-effective treatments to increase platelets are necessary.

Estimating healthcare resource use associated with the treatment of metastatic melanoma in eight countries

Objectives Studies reporting healthcare resourse use (HRU) for melanoma, one of the most costly cancers to treat, are limited. Using consistent, robust methodology, this study estimated HRU associated with the treatment of metastatic melanoma in eight countries.

Methods Using published literature and clinician input, treatment phases were identified: active systemic treatment (pre-progression); disease progression; best supportive care (BSC)/palliative care; and terminal care. HRU elements were identified for each phase and estimates of the magnitude and frequency of use in clinical practice were obtained through country-specific Delphi panels, comprising healthcare professionals with experience in oncology (n?=?8).

Results Medical oncologists are the key care providers for patients with metastatic melanoma, although in Germany dermato-oncologists also lead care. During the active systemic treatment phase, each patient was estimated to require 0.83–2 consultations with a medical oncologist/month across countries; the median number of such assessments in 3 months was highest in Canada (range?=?3.5–5) and lowest in France, the Netherlands and Spain (1). Resource use during the disease progression phase was intensive and similar across countries: all patients were estimated to consult with medical oncologists and 10–40% with a radiation oncologist; up to 40% were estimated to require a brain MRI scan. During the BSC/palliative care phase, all patients were estimated to consult with medical oncologists, and most to consult with a primary care physician (40–100%).

Limitations Panelists were from centers of excellence, thus results may not reflect care within smaller hospitals; data obtained from experts may be less variable than data from broader clinical practice. Treatments for metastatic melanoma are continually emerging, thus some elements of our work could be superseded.

Conclusions HRU estimates were substantial and varied across countries for some resources. These data could be used with country-specific costs to elucidate costs for the management of metastatic melanoma.
