Budget impact analysis of a digital monitoring platform for COPD.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a progressive debilitating condition with frequent exacerbations that have a high burden for patients and society. Digital tools may help to reduce the economic burden for patients and payers by improving outcomes. The Propeller platform is a digital self-management tool that facilitates passive monitoring of inhaler medication utilization, potentially assisting the healthcare team to identify patients at risk of a COPD exacerbation who may require further intervention. This study estimated the budget impact of Propeller from commercial payer and Medicare fee-for-service payer perspectives. METHODS: An Excel-based model was used to estimate the budget impact of Propeller for COPD patients in commercial and Medicare population sizes of 5 million members. Data on prevalence, baseline healthcare resource utilization (HCRU), and baseline use of rescue and controller inhaler medications with unit costs (adjusted to 2020 US dollars) were obtained from peer-reviewed literature. Data on reductions in HCRU during Propeller usage were based on direct evidence. Estimates for costs of remote monitoring were obtained from publicly available information. All patients were assumed to have insurance claims related to ongoing remote monitoring. RESULTS: The estimated number of annual eligible COPD patients for commercial and Medicare was 212,200 and 606,600, respectively. Propeller decreased costs by an estimated $2,475 (commercial) and $915 (Medicare) per enrolled patient. The greatest increase in expenditure was for remote monitoring related expenses. After accounting for estimated reductions in hospitalizations, emergency department visits and short-acting beta-agonist use, total net savings were approximately $1.60 and $1.70 per-member per-month for commercial and Medicare payers, respectively. CONCLUSION: Propeller is projected to be cost saving from both the commercial and Medicare payer perspectives.

The budget impact of enzyme replacement therapy in type 1 Gaucher disease in the United States.

AIM: Gaucher disease (GD) is a rare autosomal recessive condition. Type 1 GD (GD1) is the most prevalent form of GD in Western countries; enzyme replacement therapy (ERT) is a treatment option for patients with GD1. To understand the economic value of the GD1 ERT velaglucerase alfa, a budget impact model (BIM) was developed from a United States (US) payer perspective. METHODS: We estimated the budget impact of velaglucerase alfa for a 10-million-member US health plan by comparing the annual total costs of therapy between a scenario using current velaglucerase alfa uptake to a projected scenario with increased velaglucerase alfa uptake. Total drug costs for both scenarios were estimated as the sum of the product of the number of eligible patients on each treatment and the annual per-patient cost of each medication. Average per-patient costs for ERTs were calculated by adding the yearly drug acquisition, drug administration, and site-of-care markup costs. The budget impact was measured over years 1-3. RESULTS: An estimated 65 patients would receive velaglucerase alfa treatment in year 1, increasing to 90 patients by year 3. Across analyses, cost savings were realized with velaglucerase alfa compared with imiglucerase ($115,909) and taliglucerase alfa ($80,401). An annual total budget savings of $8.67 million could be realized for a hypothetical 10-million-member US health plan with increased velaglucerase alfa uptake. The per-member per-month costs decreased by $0.0241 across years 1-3. CONCLUSIONS: BIM results show that increased velaglucerase alfa uptake for GD1 treatment is cost-saving for US health plans.

Type 1 Gaucher disease (GD1) is a rare inherited condition. Long-term enzyme replacement therapy (ERT) can reverse and prevent complications. Imiglucerase, taliglucerase alfa, and velaglucerase alfa are 3 ERTs used to treat GD1. In this study, we estimated how increasing uptake of velaglucerase alfa vs. the other ERTs would impact the budget of a hypothetical US healthcare plan. The results show that increased uptake of velaglucerase alfa is cost-saving for US health plans.

Cost-effectiveness of statin therapy for secondary prevention among patients with coronary artery disease and baseline LDL-C 70-100 mg/dL in Taiwan.

BACKGROUND: The recommended target low-density lipoprotein cholesterol (LDL-C) level for coronary artery disease (CAD) patients has been lowered from 100 to 70 mg/dL in several clinical guidelines for secondary prevention. We aimed to assess whether initiating statin treatment in CAD patients with baseline LDL-C 70-100 mg/dL in Taiwan could be cost-effective. METHODS: A Markov model was developed to simulate a hypothetical cohort of CAD patients with a baseline LDL-C level of 90 mg/dL. The incidence and recurrence of MI and stroke related to specific LDL-C levels as well as the statin effect, mortality rate, and health state utilities were obtained from the literature. The direct medical costs and rate of fatal events were derived from the national claims database. The incremental cost-effectiveness ratio (ICER) per quality-adjusted life years (QALYs) was calculated, and sensitivity analyses were performed. RESULTS: Moderate-intensity statin use, a treatment regimen expected to achieve LDL <70 mg/dL in the base case, resulted in a net gain of 562 QALYs but with an additional expenditure of $11.4 million per 10,000 patients over ten years. The ICER was $20,288 per QALY gained. The probabilities of being cost-effective at willingness-to-pay thresholds of one and three gross domestic product per capita ($24,329 in 2017) per QALY were 51.1% and 94.2%, respectively. Annual drug cost was the most influential factor on the ICER. CONCLUSION: Lowering the target LDL-C level from 100 to 70 mg/dL among treatment-naïve CAD patients could be cost-effective given the health benefits of preventing cardiovascular events and deaths.

The association between insurance coverage for insulin pen needles and healthcare resource utilization among insulin-dependent patients with diabetes in China.

BACKGROUND: Pen needles are an important component of insulin delivery among patients with diabetes, but are not universally covered in China. We compared clinical and economic characteristics of insulin-dependent patients in China who have some level of pen needle (PN) reimbursement to those with no PN reimbursement. METHODS: A cross-sectional study was conducted among 400 insulin users with Type 1 or Type 2 diabetes treated in outpatient endocrinology units of four large tertiary care hospitals in Nanjing, Chongqing, Beijing and Zhengzhou. Demographics, medical history, healthcare resource utilization (RU), out-of-pocket costs, insurance and PN reimbursement status were surveyed. Unit costs were assigned to healthcare RU and compared using descriptive statistics and multivariate regression models. RESULTS: A total of 400 patients were analyzed; 142 (35.5%) with some level of PN coverage/reimbursement and 258 (64.5%) without. Patients without PN reimbursement had a higher prevalence of lipohypertrophy (59.3% vs. 40.7%, p = 0.0007), greater median PN reuse (12 vs. 7 times per needle, p < 0.0001), greater 6-month insulin costs (1591 vs. 1328 Renminbi [RMB], p = 0.0025) and total unadjusted 6-month expenditures (6433 vs. 4432 RMB, p < 0.0001), respectively. After controlling for clinical and demographic characteristics, patients without PN reimbursement had 4.6 times greater odds of high costs compared to those with PN reimbursement. CONCLUSIONS: Insulin users without PN reimbursement may pose a greater economic burden to China compared to those with PN reimbursement. Expansion of insurance coverage for insulin PNs can improve the quality of care and potentially help reduce the economic burden in this population.

Mortality, Hospital Costs, Payments, and Readmissions Associated With Clostridium difficile Infection Among Medicare Beneficiaries.

BACKGROUND: The management of Clostridium difficile infection (CDI) among hospitalized patients is costly, and ongoing payment reform is compelling hospitals to reduce its burden. To assess the impact of CDI on mortality, hospital costs, healthcare use, and Medicare payments for beneficiaries who were discharged with CDI listed as a secondary International Classification of Diseases, Ninth Revision, Clinical Modification claim diagnosis. METHODS: Data were analyzed from the 2009 to 2010 5% random sample Medicare Standard Analytic Files of beneficiary claims. Patients with index hospitalizations with CDI as a secondary diagnosis and no previous hospitalization within 30 days were identified. Outcomes included inpatient and 30-day mortality, inpatient costs, index hospital payments, all-provider payments, net hospital losses, payment to cost ratio, length of stay (LOS), and 30-day readmission; outcomes were each risk adjusted using propensity score matching and regression modeling techniques. RESULTS: A total of 3262 patients with CDI were identified after matching to patients without a CDI diagnosis. After risk adjustment, secondary CDI was associated with statistically significantly (all P < 0.05) greater inpatient mortality (3.1% vs. 1.7%), 30-day mortality (4.1% vs. 2.2%), longer LOS (7.0 days vs. 3.8 days), higher rates of 30-day hospital readmissions (14.8% vs. 10.4%), and greater hospital costs ($16,184 vs. $13,954) compared with the non-CDI cohort. The risk-adjusted payment-to-cost ratio was shown to be lower for patients with CDI than those without (0.76 vs. 0.85). CONCLUSIONS: Secondary CDI is associated with greater adjusted mortality, costs, LOS, and hospital readmissions, while receiving similar hospital reimbursement compared with patients without CDI in a Medicare population.

Adherence and persistence associated with an appointment-based medication synchronization program.

OBJECTIVE: To assess the impact of an appointment-based medication synchronization (ABMS) program on medication adherence and persistence with chronic medications. DESIGN Quasiexperimental study in which study patients were matched with control patients. SETTING: Rural pharmacies in the Midwestern United States between June 30, 2011, and October 31, 2012. PATIENTS: Individuals receiving at least two refills for one of six categories of medications to treat chronic diseases (i.e., angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, beta blockers, dihydropyridine calcium channel blockers, thiazide diuretics, metformin, statins). INTERVENTION: Patients in the ABMS program were compared with control patients receiving usual care. MAIN OUTCOME MEASURES: 1-year adherence rates using proportion of days covered (PDC) and 1-year nonpersistence rates. RESULTS: Depending on the drug class, patients enrolled in the medication synchronization program (n = 47-81) had adherences rates of 66.1% to 75.5% during 1 year versus 37.0% to 40.8% among control patients. Program patients had 3.4 to 6.1 times greater odds of adherence compared with control patients. Control patients were 52% to 73% more likely to stop taking their chronic medications over 1 year. CONCLUSION: An ABMS program in community pharmacies was associated with improved patient adherence and reduced likelihood of nonpersistence.

The economic burden of opioid-related poisoning in the United States.

OBJECTIVE: To estimate the yearly economic burden of opioid-related poisoning in the United States. BACKGROUND: Rates of opioid poisoning and related mortality have increased substantially over the past decade. Although previous studies have measured the costs of misuse and abuse, costs related specifically to opioid poisoning have not been quantified. This study quantifies the economic burden of opioid poisoning in the United States to help evaluate the economic case for efforts to reverse or prevent opioid poisoning and its associated morbidity and mortality. METHODS: Mean costs and prevalence estimates were estimated using publically available datasets. A societal perspective was assumed and accordingly estimated direct medical and productivity costs. Direct medical costs included treatment for opioid poisoning in the emergency department (ED) and inpatient settings, along with emergency transport and drug costs. Productivity costs were estimated using the human capital method and included lost wages due to mortality and absenteeism costs from ED visits and hospitalizations. All costs were inflated to 2011 U.S. dollars. RESULTS: In 2009, total costs were estimated at approximately $20.4 billion with indirect costs constituting 89% of the total. Direct medical costs were approximately $2.2 billion. ED costs and inpatient costs were estimated to be $800 million and $1.3 billion, respectively. Absenteeism costs were $335 million and lost future earnings due to mortality were $18.2 billion. CONCLUSION: Opioid-related poisoning causes a substantial burden to the United States each year. Costs related to mortality account for the majority of costs. Interventions designed to prevent or reverse opioid-related poisoning can have significant impacts on cost, especially where death is prevented.

Characterization of continued antibacterial therapy after diagnosis of hospital-onset Clostridium difficile infection: implications for antimicrobial stewardship.

STUDY OBJECTIVES: To determine the proportion of hospitalized adults with hospital-onset Clostridium difficile infection (CDI) who continued to receive concomitant non-CDI antibacterial agents, to characterize the antibacterial therapy that these patients received before and after the diagnosis of CDI, and to compare hospital outcomes between those patients who did and those who did not have their previous antibacterial therapy discontinued after CDI diagnosis. DESIGN: Retrospective cohort study. DATA SOURCE: Drug use and administrative discharge data from 42 United States academic medical centers. PATIENTS: A total of 5968 adult inpatients with hospital-onset CDI between January 1, 2002, and June 30, 2006. MEASUREMENTS AND MAIN RESULTS: We characterized patient-level antibacterial agent use before and after CDI diagnosis. Overall, 3479 patients (58.3%) continued antibacterial therapy for 2 or more days after CDI diagnosis (interhospital range 6.7-72.2%). Although the number of different antibacterial agents received in the week preceding CDI diagnosis was positively associated with continued antibacterial therapy, the relationship between continuation and severity of illness was statistically significant but nonlinear. Patients who were receiving oral vancomycin alone were less likely to have antibacterial therapy continued (28/61 patients [45.9%]) than patients receiving metronidazole alone (1154/2333 patients [49.5%]) or receiving both metronidazole and oral vancomycin (2297/3576 [64.2%]). After adjusting for confounders, patients who continued to receive antibacterial therapy had a 62.7% (95% confidence interval [CI] 48.6-78.0%, p<0.001) longer length of hospital stay after CDI diagnosis than those who did not continue therapy; the adjusted odds of mortality and odds of readmission were 1.7 (95% CI 1.4-2.1, p<0.001) and 1.2 (95% CI 1.1-1.5, p=0.025) times higher, respectively, with continued antibacterial therapy. CONCLUSION: A majority of patients with CDI continued to receive antibacterial agents after their CDI diagnosis, although the interhospital range was large. Compared with patients who did not continue therapy, hospital length of study, mortality, and subsequent admissions among patients who continued their antibacterial therapy remained significantly higher after adjusting for confounders. The adverse outcomes associated with continued therapy likely reflect the severity of the underlying primary infection and/or a poorer response to CDI therapy, suggesting an opportunity for antimicrobial stewardship programs to make important contributions to patient care.
