Estimating the economic impact of acute coronary syndrome in New Zealand over time (ANZACS-QI 64): a national registry-based cost burden study.

OBJECTIVES: To estimate the changes in costs associated with acute coronary syndrome (ACS) admissions in New Zealand (NZ) public hospitals over a 12-year period. DESIGN: A cost-burden study of ACS in NZ was conducted from the NZ healthcare system perspective. SETTING: Hospital admission costs were estimated using relevant diagnosis-related groups and their costs for publicly funded casemix hospitalisations, and applied to 190 364 patients with ACS admitted to NZ public hospitals between 2007 and 2018 identified from routine national hospital datasets. Trends in the costs of index ACS hospitalisation, hospital admissions costs, coronary revascularisation and all-cause mortality up to 1 year were evaluated. All costs were presented as 2019 NZ dollars. PRIMARY OUTCOME MEASURES: Healthcare costs attributed to ACS admissions in NZ over time. RESULTS: Between 2007 and 2018, there was a 42% decrease in costs attributed to ACS (NZ$7.7 million (M) to NZ$4.4 M per 100 000 per year), representing a decrease of NZ$298 827 per 100 000 population per year. Mean admission costs associated with each admission declined from NZ$18 411 in 2007 to NZ$16 898 over this period (p<0.001) after adjustment for key clinical and procedural characteristics. These reductions were against a background of increased use of coronary revascularisation (23.1% (2007) to 38.1% (2018)), declining ACS admissions (366-252 per 100 000 population) and an improvement in 1-year survival post-ACS. Nevertheless, the total ACS cost burden remained considerable at NZ$237 M in 2018. CONCLUSIONS: The economic cost of hospitalisations for ACS in NZ decreased considerably over time. Further studies are warranted to explore the association between reductions in ACS cost burden and changes in the management of ACS.

Costs Associated with Laser Interstitial Thermal Therapy Are Lower Than Anterior Temporal Lobectomy for Treatment of Temporal Lobe Epilepsy.

BACKGROUND: Laser interstitial thermal therapy (LITT) is a minimally invasive alternative to anterior temporal lobectomy (ATL) for treatment of temporal lobe epilepsy. It has gained popularity as familiarity with technique increases and outcomes are better characterized. There has been no direct cost comparison between the 2 techniques in literature to date. The current study directly compares hospital costs associated with LITT with those of ATL patients and analyzes the factors potentially responsible for those costs. METHODS: Patients who underwent ATL (27) and LITT (15) were retrospectively reviewed for total hospital costs along with demographic, surgical, and postoperative factors potentially affecting cost. T-tests were used to compare costs and independent linear regressions, and hierarchical regressions were used to examine predictors of cost for each procedure. RESULTS: Mean hospital costs of admission for single-trajectory LITT ($104,929.88) were significantly less than for ATL ($134,980.04) (P = 0.001). In addition, length of stay, anesthesia costs, operative room costs, and postoperative hospitalization costs were all significantly lower in LITT. CONCLUSIONS: Given the minimally invasive nature of LITT, it is associated with shorter length of stay and lower hospital costs than ATL in the first head-to-head comparison of procedural costs in literature to date. Long-term efficacy as it relates to these costs associated with LITT and ATL should be further investigated to better characterize the utility of LITT in temporal lobe epilepsy patients.

Contemporary procedure characteristics and outcomes of accessory atrioventricular pathway ablations in an integrated community-based health care system using a tiered approach.

BACKGROUND: Since the early descriptions of large series of accessory atrioventricular pathway ablations in adults and adolescents over 20 years ago, there have been limited published reports based on more recent experiences of large referral centers. We aimed to characterize accessory pathway distribution and features in a large community-based population that influence ablation outcomes using a tiered approach to ablation. METHODS: Retrospective analysis of 289 patients (age 14-81) who underwent accessory ablation from 2015-2019 was performed. Pathways were categorized into anteroseptal, left freewall, posteroseptal, and right freewall locations. We analyzed patient and pathway features to identify factors associated with prolonged procedure time parameters. RESULTS: Initial ablation success rate was 94.7% with long-term success rate of 93.4% and median follow-up of 931 days. Accessory pathways were in left freewall (61.6%), posteroseptal (24.6%), right freewall (9.6%), and anteroseptal (4.3%) locations. Procedure outcome was dependent on pathway location. Acute success was highest for left freewall pathways (97.1%) with lowest case times (144 ± 68 min) and fluoroscopy times (15 ± 19 min). Longest procedure time parameters were seen with anteroseptal, left anterolateral, epicardial-coronary sinus, and right anterolateral pathway ablations. CONCLUSIONS: In this community-based adult and adolescent population, majority of the accessory pathways are in the left freewall and posteroseptal region and tend to be more easily ablated. A tiered approach with initial use of standard ablation equipment before the deployment of more advance tools, such as irrigated tips and 3D mapping, is cost effective without sacrificing overall efficacy.

Results from an Epidemiological Follow-Up Survey on Home Artificial Nutrition in Switzerland from 2010 to 2015.

BACKGROUND: Home artificial nutrition (HAN) is an established treatment for malnourished patients. Since July 2012, the costs for oral nutrition supplements (ONS) are covered by the compulsory health insurance providers in Switzerland if the patient has a medical indication based on the Swiss Society for Clinical Nutrition guidelines. Therefore, the purpose of our study was to analyse the development of HAN, including ONS, before and after July 2012. METHODS: We obtained the retrospective and anonymized data from the Swiss association for joint tasks of health insurers (SVK), who registered patients on HAN. Since not all health insurers are working with SVK, this retrospective study recorded nearly 65% of all new patients on HAN in Switzerland from January 1, 2010, to December 31, 2015. RESULTS: A total of 33,410 patients (49.1% men and 50.9% women) with a mean BMI of 21.3 ± 4.5 kg/m2 and mean age of 68.9 ± 17.8 years were recorded. The number of patient cases on ONS increased from 808 cases in 2010 to 18,538 cases in 2015, while patient cases on home enteral nutrition (HEN) and home parenteral nutrition (HPN) remained approximately the same. The relative distribution of type of HAN changed from 26.2% cases on ONS, 68.7% cases on HEN and 5.1% cases on HPN in 2010 to 86.1% cases on ONS, 12.8% cases on HEN, and 1.1% cases on HPN in 2015. Treatment duration decreased for ONS from 698 ± 637 days to 171 ± 274 days, for HEN from 416 ± 553 days to 262 ± 459 days, and for HPN from 96 ± 206 days to 72 ± 123 days. Mean costs per patient decreased for ONS from 1,330 CHF in 2010 to 606 CHF in 2015. Total costs for HAN increased from 16,895,373 CHF in 2010 to 32,868,361 CHF in 2015. CONCLUSION: Our epidemiological follow-up study showed an immense increase in number of patients on HAN in Switzerland after July 2012. Due to shorter therapy duration and reduced mean costs per patient, total costs were only doubled while the number of patients increased 7-fold.

What Are the Costs of Cervical Radiculopathy Prior to Surgical Treatment?

STUDY DESIGN: Retrospective, observational study. OBJECTIVE: To examine the costs associated with nonoperative management (diagnosis and treatment) of cervical radiculopathy in the year prior to anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND DATA: While the costs of operative treatment have been previously described, less is known about nonoperative management costs of cervical radiculopathy leading up to surgery. METHODS: The Humana claims dataset (2007-2015) was queried to identify adult patients with cervical radiculopathy that underwent ACDF. Outcome endpoint was assessment of cumulative and per-capita costs for nonoperative diagnostic (x-rays, computed tomographic [CT], magnetic resonance imaging [MRI], electromyogram/nerve conduction studies [EMG/NCS]) and treatment modalities (injections, physical therapy [PT], braces, medications, chiropractic services) in the year preceding surgical intervention. RESULTS: Overall 12,514 patients (52% female) with cervical radiculopathy underwent ACDF. Cumulative costs and per-capita costs for nonoperative management, during the year prior to ACDF was $14.3 million and $1143, respectively. All patients underwent at least one diagnostic test (MRI: 86.7%; x-ray: 57.5%; CT: 35.2%) while 73.3% patients received a nonoperative treatment. Diagnostic testing comprised of over 62% of total nonoperative costs ($8.9 million) with MRI constituting the highest total relative spend ($5.3 million; per-capita: $489) followed by CT ($2.6 million; per-capita: $606), x-rays ($0.54 million; per-capita: $76), and EMG/NCS ($0.39 million; per-capita: $467). Conservative treatments comprised of 37.7% of the total nonoperative costs ($5.4 million) with injections costs constituting the highest relative spend ($3.01 million; per-capita: $988) followed by PT ($1.13 million; per-capita: $510) and medications (narcotics: $0.51 million, per-capita $101; gabapentin: $0.21 million, per-capita $93; NSAIDs: 0.107 million, per-capita $47), bracing ($0.25 million; per-capita: $193), and chiropractic services ($0.137 million; per-capita: $193). CONCLUSION: The study quantifies the cumulative and per-capital costs incurred 1-year prior to ACDF in patients with cervical radiculopathy for nonoperative diagnostic and treatment modalities. Approximately two-thirds of the costs associated with cervical radiculopathy are from diagnostic modalities. As institutions begin entering into bundled payments for cervical spine disease, understanding condition specific costs is a critical first step. LEVEL OF EVIDENCE: 3.

How Transparency Efforts Helped One System's Financial Turnaround.

Healthcare consumerism, costs, and price transparency are garnering unprecedented attention from hospitals and health systems in the United States. To many observers of the US healthcare delivery system, the inability to provide accurate pricing information and the variability in prices for comparable services are utter failures of the administrative infrastructure that supports patient care processes.Price transparency and the affordability of healthcare have also become top concerns for professional and trade organizations, which are devoting significant resources to assist member institutions in facing these issues. In many states, elected officials have passed legislation requiring pricing support for consumers. When the value equation (cost divided by quality) is considered, comparisons of healthcare providers can become even more confusing.Price transparency and demonstration of cost-effective, high-quality service to patients have become strategic imperatives at Maricopa Integrated Health System (MIHS). A safety-net system and one of Arizona's largest providers of graduate medical education and other teaching programs, MIHS faced an operating deficit of more than $74 million in fiscal year 2014. In 2015, financial concerns prompted the CEO and board to hold weekly meetings to appraise cash availability and management interventions. Over the next four years, MIHS achieved a cumulative improvement in net income of more than $150 million. Today, MIHS is reinventing itself through a major capital campaign made possible in part by a $935 million public bond referendum passed by the voters of Maricopa County. Ultimately, our ability to better serve the community involves connecting with our patients and addressing their need for price transparency.

Economic Impact of Diabetes in Japan.

PURPOSE OF REVIEW: The economic burden of diabetes in Japan is already serious and will become greater in the future. We review the economic impact of diabetes in Japan to examine viable options for mitigating its effects. RECENT FINDINGS: Medical costs for diabetes have been increasing by US $1 million annually, reaching US $11 million in 2009, of which US $7 million was accounted for by people aged 65 years or older. The quality of treatment of diabetes in Japan is higher than in other regions in the world. This can be more effective for achieving glycemic control, but is also more expensive compared with conventional treatment. Because of the high cost of diabetes in Japan, a coordinated response is needed. Intervention trials for people with prediabetes aimed at preventing the occurrence of diabetes seem to be the most cost-effective method for lowering the medical costs of diabetes, rather than the use of new, expensive antidiabetic drugs in patients with established diabetes.

A Patient-Reported Outcome Instrument to Assess Symptom Burden and Predict Survival in Patients with Advanced Cancer: Flipping the Paradigm to Improve Timing of Palliative and End-of-Life Discussions and Reduce Unwanted Health Care Costs.

BACKGROUND: Discussions regarding palliative care and end-of-life care issues are frequently delayed past the time of usefulness, resulting in unwanted medical care. We sought to develop a patient-reported outcome (PRO) instrument that allows patients to voice their symptom burdens and facilitate timing of discussions. SUBJECTS, MATERIALS, AND METHODS: A seven-item PRO instrument (Cota Patient Assessed Symptom Score-7 item [CPASS-7]) covering physical performance status, pain, burden, and depression was administered (September 2015 through October 2016) with correlation to overall survival, correcting for time to complete survey since diagnosis. RESULTS: A total of 1,191 patients completed CPASS-7 at a median of 560 days following the diagnosis of advanced cancer. Of these patients, 49% were concerned that they could not do the things they wanted; 35% reported decreased performance status. Financial toxicity was reported by 39% of patients, with family burdens noted in 25%. Although depression was reported by 15%, 43% reported lack of pleasure. Pain was reported by 33%. The median CPASS-7 total symptom burden score was 16 (possible 0-112). With a median follow-up of 15 months from initial survey, 46% had died. Patients with symptom burden scores <29 and ≥29 had a 6-month overall survival rate of 87% and 67%, respectively, and 12-month survival rates of 72% and 50%. A one-point score increase resulted in a 1.8% increase in expected hazard. CONCLUSION: Patients with advanced cancer with higher levels of symptom burden, as self-reported on the CPASS-7, had inferior survival. The PRO facilitates identification of patients appropriate for reassessment of treatment goals and potentially palliative and end-of-life care in response to symptom burden concerns. IMPLICATIONS FOR PRACTICE: A seven-item patient-reported outcome (PRO) instrument was administered to 1,191 patients with advanced cancers. Patients self-reporting higher levels of physical and psychological symptom burden had inferior overall survival rates. High individual item symptom PRO responses should serve as a useful trigger to initiate supportive interventions, but when scores indicate global problems, discussions regarding end-of-life care might be appropriate.

THE FUTURE OF CARDIOVASCULAR CARE: FROM AFFORDABLE CARE TO THE ACADEMIC MEDICAL CENTER.

We are presently seeing exponential advances in medical knowledge and development of therapeutic and diagnostic tools. We have also begun to experience an historic restructuring of our health care system. But health care costs continue to rise, disparities persist, and the chaotic, disjointed, and often thoughtless discourse in Washington threatens to roll back the prior advances. Improvement in patient care will be severely stymied if the threats to academic medical centers are not countered. This paper will explore our present state through the lens of cardiovascular care. It will 1) examine clinical trends; 2) dissect the value and challenges to the Patient Protection and Affordable Care Act; 3) highlight limitations and alternatives to relying on the federal government; and 4) present the Academic Medical System construct, as a structure designed to retain and advance the academic mission.

A case-mix classification system for explaining healthcare costs using administrative data in Italy.

BACKGROUND: The Italian National Health Service (NHS) provides universal coverage to all citizens, granting primary and hospital care with a copayment system for outpatient and drug services. Financing of Local Health Trusts (LHTs) is based on a capitation system adjusted only for age, gender and area of residence. We applied a risk-adjustment system (Johns Hopkins Adjusted Clinical Groups System, ACG® System) in order to explain health care costs using routinely collected administrative data in the Veneto Region (North-eastern Italy). METHODS: All residents in the Veneto Region were included in the study. The ACG system was applied to classify the regional population based on the following information sources for the year 2015: Hospital Discharges, Emergency Room visits, Chronic disease registry for copayment exemptions, ambulatory visits, medications, the Home care database, and drug prescriptions. Simple linear regressions were used to contrast an age-gender model to models incorporating more comprehensive risk measures aimed at predicting health care costs. RESULTS: A simple age-gender model explained only 8% of the variance of 2015 total costs. Adding diagnoses-related variables provided a 23% increase, while pharmacy based variables provided an additional 17% increase in explained variance. The adjusted R-squared of the comprehensive model was 6 times that of the simple age-gender model. CONCLUSIONS: ACG System provides substantial improvement in predicting health care costs when compared to simple age-gender adjustments. Aging itself is not the main determinant of the increase of health care costs, which is better explained by the accumulation of chronic conditions and the resulting multimorbidity.

Financing the Primary Care Behavioral Health Model.

The PCBH model of integrated care blends behavioral health professionals into the primary care team, thereby enhancing the scope of primary care and expanding the range of services provided to the patient. Despite promising evidence in support of the model and a growing number of advocates and practitioners of PCBH integration, current reimbursement policies are not always favorable. As the nation's healthcare system transitions to value-based payment models, new financing strategies are emerging which will further support the viability of PCBH integration. This article provides an overview of the infrastructure necessary to support PCBH practice; reviews the current PCBH funding landscape; discusses how emerging trends in healthcare financing are impacting the model; and provides a vision for the viability of the PCBH model within the value-based financing of our healthcare system in the future.

Forecasting the future burden of opioids for osteoarthritis.

OBJECTIVE: To quantify the current national burden of opioids for osteoarthritis (OA) pain in Australia in terms of number of dispensed opioid prescriptions and associated costs, and to forecast the likely burden to the year 2030/31. DESIGN: Epidemiological modelling. METHODS: Published data were obtained on rates of opioid prescribing for people with OA and national OA prevalence projections. Trends in opioid dispensing from 2006 to 2016, and average costs for common opioid subtypes were obtained from the Pharmaceutical Benefits Scheme and Medicare Australia Statistics. Using these inputs, a model was developed to estimate the likely number of dispensed opioid prescriptions and costs to the public healthcare system by 2030/31. RESULTS: In 2015/16, an estimated 1.1 million opioid prescriptions were dispensed in Australia for 403,954 people with OA (of a total 2.2 million Australians with OA). Based on recent dispensing trends and OA prevalence projections, the number of dispensed opioid prescriptions is expected to nearly triple to 3,032,332 by 2030/31, for an estimated 562,610 people with OA. The estimated cost to the Australian healthcare system was $AUD25.2 million in 2015/16, rising to $AUD72.4 million by 2030/31. CONCLUSION: OA-related opioid dispensing and associated costs are set to increase substantially in Australia from 2015/16 to 2030/31. Use of opioids for OA pain is concerning given joint disease chronicity and the risk of adverse events, particularly among older people. These projections represent a conservative estimate of the full financial burden given additional costs associated with opioid-related harms and out-of-pocket costs borne by patients.

A window-DEA based efficiency evaluation of the public hospital sector in Greece during the 5-year economic crisis.

The main objective of this study was to apply the non-parametric method of Data Envelopment Analysis (DEA) to measure the efficiency of Greek NHS hospitals between 2009-2013. Hospitals were divided into four separate groups with common characteristics which allowed comparisons to be carried out in the context of increased homogeneity. The window-DEA method was chosen since it leads to increased discrimination on the results especially when applied to small samples and it enables year-by-year comparisons of the results. Three inputs -hospital beds, physicians and other health professionals- and three outputs-hospitalized cases, surgeries and outpatient visits- were chosen as production variables in an input-oriented 2-year window DEA model for the assessment of technical and scale efficiency as well as for the identification of returns to scale. The Malmquist productivity index together with its components (i.e. pure technical efficiency change, scale efficiency change and technological scale) were also calculated in order to analyze the sources of productivity change between the first and last year of the study period. In the context of window analysis, the study identified the individual efficiency trends together with "all-windows" best and worst performers and revealed that a high level of technical and scale efficiency was maintained over the entire 5-year period. Similarly, the relevant findings of Malmquist productivity index analysis showed that both scale and pure technical efficiency were improved in 2013 whilst technological change was found to be in favor of the two groups with the largest hospitals.

Estimated Budget Impact of Increased Use of Mirabegron, A Novel Treatment for Overactive Bladder.

BACKGROUND: Oral pharmacological treatment for overactive bladder (OAB) consists of antimuscarinics and the beta-3 adrenergic agonist mirabegron. Antimuscarinic adverse events (AEs) such as dry mouth, constipation, and blurry vision can result in frequent treatment discontinuation rates, leaving part of the OAB population untreated. Antimuscarinics also contribute to a patient's anticholinergic cognitive burden (ACB), so the Beers Criteria recommends cautious use of antimuscarinics in elderly patients who take multiple anticholinergic medications or have cognitive impairment. Since mirabegron does not affect the cholinergic pathways, it is unlikely to contribute to a patient's ACB. OBJECTIVE: To estimate the health care costs associated with the pharmacological treatment of OAB with mirabegron and antimuscarinics from U.S. commercial payer and Medicare Advantage perspectives, using a budget impact model. METHODS: For this budget impact model, 2 analyses were performed. The primary analysis estimated the budgetary impact of increasing the use of mirabegron in a closed patient cohort treated with oral pharmacological treatments. The secondary analysis modeled the economic impact in an open cohort by allowing untreated patients to begin treatment with mirabegron after potential contraindication, intolerance, or lack of effectiveness of antimuscarinics. The analyses were performed over a 3-year time horizon. The economic impact of increased mirabegron use was quantified using direct medical costs, including prescription costs and health resource utilization (HRU) costs. Costs of comorbidities included pharmacy and medical costs of treating OAB-related urinary tract infections (UTI), skin rashes, and depression. An analysis of a large single-site integrated health network database was commissioned to quantify ACB-related HRU in terms of the increases in yearly outpatient and emergency department visits. Based on this analysis, the model associated each unit increase in ACB score with increased HRU and probability of mild cognitive impairment. Clinical outcomes of increased use of mirabegron were presented as the number of AEs and comorbidity episodes that could be avoided. One-way sensitivity analyses were performed to quantify the expected budget impact over the range of uncertainty for the key input variables. RESULTS: Primary analysis calculated the impact of increasing the use of mirabegron from 4.5% to 5.3%, 7.1%, and 9.4% in years 1, 2, and 3, respectively, among oral pharmacological OAB treatments that included generic and branded antimuscarinics: oxybutynin, tolterodine, trospium, darifenacin, fesoterodine, and solifenacin. For a 1 million-member U.S. commercial payer plan, the total prescription costs increased, and the total medical costs decreased during the 3-year time horizon, yielding increases of $0.005, $0.016, and $0.031 from current per member per month (PMPM) costs and $0.90, $2.92, and $5.53 from current per treated member per month (PTMPM) costs, an average of less than 2% of current OAB treatment costs. For the Medicare Advantage plan, the resulting incremental PMPM costs were $0.010, $0.034, and $0.065, and the incremental PTMPM costs were $0.93, $3.04, and $5.76; all were less than 4% of the current cost. The secondary analysis estimated the budgetary effects of reducing the untreated population by 1% annually by initiating treatment with mirabegron. For a commercial payer, this resulted in PMPM cost increases of $0.156, $0.311, and $0.467 from the current value, while the incremental PTMPM cost increased by $6.17, $11.67, and $16.61. For the Medicare Advantage plan, the incremental increases in PMPM costs were $0.277, $0.553, and $0.830, and in PTMPM costs were $6.42, $12.15, and $17.29. Clinically, treating more OAB patients resulted in fewer OAB-related comorbidities from both health plan perspectives, since most events associated with nontreatment could be avoided. In the Medicare Advantage population of the secondary analysis, the total numbers of avoided events were predicted as 452 UTIs, 2,598 depression diagnoses, and 3,020 skin rashes during the time horizon of the model. CONCLUSIONS: Mirabegron addresses an unmet need for therapy for certain OAB patients, for whom antimuscarinics are not recommended because of a risk of cognitive impairment and who are intolerant to the anticholinergic AEs. Using mirabegron involves moderate additional economic cost to a commercial or Medicare Advantage health plan for which medical cost savings can offset a substantial part of increased pharmacy costs.

Docosahexaenoic acid supplementation (DHA) and the return on investment for pregnancy outcomes.

The Kansas University DHA Outcomes Study (KUDOS) found a significant reduction in early preterm births with a supplement of 600mg DHA per day compared to placebo. The objective of this analysis was to determine if hospital costs differed between groups. We applied a post-hoc cost analysis of the delivery hospitalization and all hospitalizations in the following year to 197 mother-infant dyads who delivered at Kansas University Hospital. Hospital cost saving of DHA supplementation amounted to $1678 per infant. Even after adjusting for the estimated cost of providing 600mg/d DHA for 26 weeks ($166.48) and a slightly higher maternal care cost ($26) in the DHA group, the net saving per dyad was $1484. Extrapolating this to the nearly 4 million US deliveries per year suggests universal supplementation with 600mg/d during the last 2 trimesters of pregnancy could save the US health care system up to USD 6 billion.

Economic impact of expanded use of biologic therapy for the treatment of rheumatoid arthritis and Crohn's disease in Argentina, Brazil, Colombia, and Mexico.

OBJECTIVES: To estimate economic impact resulting from increased biologics use for treatment of rheumatoid arthritis (RA) and Crohn's disease (CD) in Argentina, Brazil, Colombia, and Mexico. METHODS: The influence of increasing biologics use for treatment of RA during 2012-2022 and for treatment of CD during 2013-2023 was modeled from a societal perspective. The economic model incorporated current and projected medical, indirect, and drug costs and epidemiologic and economic factors. Costs associated with expanded biologics use for RA were compared with non-expanded use in Argentina, Brazil, Colombia, and Mexico. A similar analysis was conducted for CD in Brazil, Colombia, and Mexico. RESULTS: Accounting for additional costs of biologics and medical and indirect cost offsets, the model predicts that expanded use of biologics for patients with RA from 2012 to 2022 will result in cumulative net cost savings of ARS$2.351 billion in Argentina, R$9.004 billion in Brazil, COP$728.577 billion in Colombia, and MXN$18.02 billion in Mexico; expanded use of biologics for patients with CD from 2013 to 2023 will result in cumulative net cost savings for patients with CD of R$0.082 billion in Brazil, COP$502.74 billion in Colombia, and MXN$1.80 billion in Mexico. Indirect cost offsets associated with expanded biologics use were a key driver in reducing annual per-patient net costs for RA and CD. LIMITATIONS: Future economic projections are limited by the potential variance between projected and actual future values of biologic prices, wages, medical costs, and gross national product for each country. CONCLUSIONS: Increasing biologics use to treat RA and CD may limit cost growth over time by reducing medical and indirect costs. These findings may inform policy decisions regarding biologics use in Argentina, Brazil, Colombia, and Mexico.
