Abstract
Background Health systems need to optimize the use of resources, especially in high-cost diseases as rheumatoid arthritis (RA). We aimed to evaluate the efficiency of using centers of excellence (CoE) as a strategy for improving RA treatment in Colombia. Methods A cost description analysis was carried out using the standard costing technique. We estimated the costs of medical consultations, laboratories, images, and medications for RA. Categories of care standards stratified by severity were defined using the disease activity score in 28 joints (DAS28). We evaluated the impact, in terms of costs (US dollars), for providing RA clinical care for a previously described cohort using the CoE approach. Statistical analyses were performed in Microsoft Excel®, and R. Results Expenditure on therapeutic drugs increases as the severity of RA increases. Drugs represent 53.6% of the total cost for the low disease activity (LDA) stage, 75.2% for moderate disease activity (MDA), 88.5% for severe disease activity (SDA) and 97% for SDA with biologic treatment (SDA+Biologic). Treating 968 patients would cost US$612,639 (US$487,978-1,220,160) at baseline, per year. After a year of follow-up at the CoE, treating the same patients would cost US$388,765 (US$321,710-708,476), which implies potential cost-savings of up to US$223,874 per year. Conclusion The strategy of providing clinical care for RA through CoE can save US$231.3 per patient-per year. The results of our study show that CoE could greatly impact the public policies dealing with treatment of RA in Colombia. Applying the CoE model in our country would both improve health outcomes, as well as being more efficient in terms of costs.

Abstract
BACKGROUND Despite the recent advances in treatments for rheumatoid arthritis (RA), there are still unmet needs in disease outcomes. This study aimed to analyze the satisfaction with drug therapies for RA according to the levels of disease severity (patient-assessed) and proportions of treatment cost to household income. METHODS This was a subgroup study of a cross-sectional study in patients with RA and their physicians. The patients were subdivided into different subgroups based on their self-assessed severity of RA and on the proportions of treatment cost to household income (<10%, 10-30%, 31-50%, and >50%). The Treatment Satisfaction Questionnaire for Medication version II was used to assess patients' treatment satisfaction. RESULTS When considering all medications, effectiveness, convenience, and global satisfaction scores were lower in the severe and moderate RA subgroups than those in the mild and extremely mild RA subgroups (all P < 0.001). Effectiveness, side effects, and convenience scores were higher in the <10% subgroup compared to those in the >50% subgroup (all P < 0.05). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 13.183, P = 0.004). For biological disease-modifying anti-rheumatic drugs, effectiveness and convenience scores were lower in the severe RA subgroup than those in the extremely mild RA subgroup (both P < 0.05). Convenience score was higher in the <10% subgroup compared to that in the 31% to 50% and >50% subgroups (F = 12.646, P = 0.005). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 8.794, P = 0.032). CONCLUSION Higher disease severity and higher financial burden were associated with lower patient satisfaction.

Disease course and healthcare costs of a cohort of rheumatoid arthritis patients from Turkey. Rheumatol Int 2020; 40:1037-1044. [PMID: 32253500 DOI: 10.1007/s00296-020-04574-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Accepted: 03/27/2020] [Indexed: 10/24/2022]
Abstract
The objective of the study is to assess the disease course and associated healthcare costs in a cohort of established rheumatoid arthritis (RA) patients in Turkey. The study cohort consisted of 75 RA patients from our outpatient clinic who took part in a previous multicenter study assessing RA-related healthcare costs 6 years ago. In March 2018, we attempted to re-evaluate these patients with the same questionnaire of the previous study enabling us to get information on medication use, comorbidities, and RA-related healthcare costs. We used RAPID-3 for assessing disease activity, HAQ-DI for functional status and EQ-5D for quality of life. Sixty-two (83%) patients were re-evaluated, seven (9.3%) had died and three (4%) were receiving palliative care following major cardiovascular events. Forty-seven (76%) patients had used at least one biologic agent during 79.1 ± 3.3 months after the previous study. At the last evaluation, 34 patients (55%) were on biologics, 22 (35%) were on csDMARDs and 6 (9.6%) were off RA treatment. The mean RAPID3 score (4.3 ± 1.6 SD) was similar to that of the previous study. HAQ-DI (0.69 ± 0.57 SD) and EQ-5D (0.68 ± 0.21 SD) scores showed significant improvement over time. Median direct costs (€2998) were higher than indirect costs (€304). Medication costs were high (€2958). Disease activity remained stable, while functional status and QoL had improved over time. Serious infections and cardiovascular disability are a concern. Medication costs are still the main determinant of RA-related healthcare costs.

Abstract
Purpose This study compared treatment patterns of Turkish patients with a diagnosis of rheumatoid arthritis (RA) who were treated with innovator Remicade® (infliximab [IFX]) and either continued IFX or switched to CT-P13. Materials and methods Adult RA patients with ≥1 IFX claim were identified from the Turkish Ministry of Health database. Eligible patients initiated and continued IFX treatment (continuers cohort [CC]) or initiated IFX and switched to CT-P13 (switchers cohort [SC]) during the study period. The initial IFX claim date was defined as the index date. The switch/reference date was defined as the CT-P13 switch date for the SC or a random IFX date during the period of CT-P13 availability for the CC. Cohorts were matched by age, sex, and number of IFX prescriptions during baseline. Patient demographics, discontinuation, and switching were summarized. The baseline period was defined as the period from the index date to the switch/reference date. The follow-up period ranged from the switch/reference date to the end of data availability. Results After matching, 697 patients were selected: 605 patients for the CC and 92 patients for the SC. Mean IFX duration for the baseline period was 422 days in the CC and 438 days in the SC. Median time on any infused tumor necrosis factor (TNF) antagonist therapy was 1,080 days in the CC and 540 days in the SC during the study period. During the follow-up period, discontinuation was lower in the CC (CC=33.9% vs SC=87.5%; P<0.001). The mean time to discontinuation was longer in the CC (CC=276 days vs SC=132 days; P<0.001). A switch to another biologic medication during the follow-up period was observed in 19.0% of patients in the CC (n=115) and 81.5% of patients in the SC (n=75; P<0.001). Conclusion Treatment patterns differed between patients prescribed IFX and CT-P13. In Turkey, RA patients maintained on IFX had greater treatment persistence (ie, fewer and later discontinuations) than those who initiated IFX and switched to CT-P13.

Abstract
Purpose Biosimilar IFX (CT-P13) received marketing approval in Turkey for treatment of rheumatologic diseases, including ankylosing spondylitis, psoriatic arthritis, rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis. Population data on real-world treatment patterns of CT-P13 following marketing approval in European countries are largely unreported. This study examined the prescribing and medication utilization patterns of innovator infliximab (IFX) and CT-P13 in Turkey for patients with RA or IBD naïve to either IFX. Materials and methods Adult patients with ≥1 diagnosis claim for RA or IBD and ≥1 claim for IFX or CT-P13 were identified in the Turkish Ministry of Health database during the following identification periods: 1 Oct 2014–30 May 2015 (RA) and 1 Oct 2014–31 Dec 2015 (IBD). Continuous medical and pharmacy coverage for ≥12 months before and after the date of the first dose (index) IFX or CT-P13 was also required. Separate analyses were done for each population. Results Seven hundred and seventy nine adult RA and 581 IBD patients met the selection criteria. The majority of RA (74%; n=575) and IBD patients (87%; n=504) were initiated on IFX. The average study observation period was 16 months for the RA and 12 months for the IBD population. Over the observation periods, discontinuation among RA patients occurred in 42% of IFX and 63% of CT-P13 while discontinuation in the IBD cohort occurred in 38% of IFX; and 62% of CT-P13. Conclusion In this population-based study, more IFX-naïve RA and IBD patients were initially treated with IFX than CT-P13. Discontinuation and switching were observed more often and earlier among patients treated with CT-P13 regardless of disease state. Further studies are needed to understand the reasons for these observed differences.

Abstract
Objectives The study aimed to assess the burden of RA among the US Medicare population (aged ≥65 years) by comparing co-morbidities, health-care resource utilization (HCRU) and costs against matched non-RA Medicare patients. Methods Data were obtained from the Medicare fee-for-service claims database from 2010 to 2013. RA Medicare patients were identically matched with Medicare patients without RA (controls) based on demographics. Bivariate analyses were conducted to examine differences between cohorts for co-morbidities, HCRU and costs. A generalized linear model was used to test relationships between patient-level characteristics, HCRU and costs. Results The study population included 115 867 RA patients and 115 867 age-, sex-, race- and region-matched non-RA controls. Mean age was 75.2 years; 79.4% were female. Co-morbidities were greater in RA vs non-RA patients [Charlson Co-morbidity Index (excluding RA): 1.86 vs 1.00; P < 0.0001]. All-cause annual HCRU was greater in RA vs non-RA patients. Total annual health-care costs were ∼3-fold higher in RA vs non-RA patients ($20 919 vs $7197, respectively; P < 0.0001) with the major driver of costs in the RA cohort being outpatient costs. Approximately half of the overall costs in the RA cohort were RA related ($11 587). After controlling for differences in patient characteristics and co-morbidities between cohorts, the adjusted total mean annual costs for RA patients were still more than twice those of non-RA patients ($16 374 vs $6712; P < 0.0001). Conclusions Among US Medicare patients, those with an RA diagnosis had a significantly greater burden of co-morbidities, HCRU and costs compared with a matched cohort without RA.

Abstract
BACKGROUND According to the Turkish Ministry of Health's guidelines, standard double therapy, a combination of pegylated interferon-alpha and ribavirin, was the only treatment option for patients with hepatitis C virus (HCV) infection until the end of 2011. OBJECTIVE The primary objective was to compare risk-adjusted clinical and economic outcomes between treated and untreated patients with HCV infection. METHODS Patients with HCV infection were identified from the Turkish National Health Insurance Database (2009-2011) using International Classification of Diseases, 10th Revision, Clinical Modification codes. The first prescription date was designated as the index date. Mortality and hepatocellular carcinoma (HCC) rates and health care costs of treated and untreated patients were compared using propensity score matching. Baseline demographic and clinical factors were controlled in the models. Subgroup analysis was conducted for patient groups with and without a cirrhosis diagnosis. RESULTS Out of 12,990 patients included in the study, 1,583 were treated for HCV infection. Out of 2,467 patients who had a cirrhosis diagnosis, 231 were treated, whereas out of 10,523 patients without cirrhosis, 1,352 patients were treated. Treated patients were younger, less likely to be diagnosed with comorbid conditions, and less likely to reside in Central or Eastern Anatolia. After adjusting for baseline demographic and clinical factors, mortality (2.27% vs. 5.31%; P < 0.001) and HCC rates (0.69% vs. 1.96%; P < 0.001) were found to be lower for treated patients. Differences were more significant among patients diagnosed with cirrhosis. Treated patients incurred higher risk-adjusted annual costs (€6172 vs. €1680; P < 0.001), mainly because of pharmaceutical costs (€4918 vs. €583; P < 0.001). CONCLUSIONS HCV infection treatment, although costly, significantly reduces mortality and HCC rates in Turkey.

Abstract
To explore healthcare costs associated with antiviral treatment of hepatitis B virus (HBV) in Turkey. Research-identified data from a claims processing system for all Turkish health insurance funds were analysed. Adult patients prescribed oral antiviral and pegylated interferon treatment were identified between 1 January 2010 and 31 December 2010. The first prescription date was defined as the index date. Patients were required to have HBV diagnosis within the 6-month pre-index period. Pharmacy, outpatient and inpatient claims were compiled over the study period for the selected patients, and risk-adjusted 1-year healthcare costs of patients with oral antiviral and pegylated interferon treatment were compared. Risk adjustment was carried out using propensity score matching, controlling for baseline demographic and clinical characteristics. A total of 9618 patients were identified, of which 9074 were treated with oral antiviral medication and 544 with pegylated interferon medication. The oral antiviral treatment group was older (45.28 vs 42.19, P < 0.001), less likely to be female (32.17% vs 39.71%, P < 0.001) and to reside in Southeastern Anatolia (8.29% vs 13.97%, P < 0.001) or Mediterranean region (8.90% vs 11.76%, P < 0.03) and had higher Elixhauser comorbidity index scores (60.22% vs 74.08%, P < 0.001) than the pegylated interferon group. After adjusting for confounding factors, total medical costs for pegylated interferon patients were €2771 higher than for oral antiviral patients (P < 0.001), due to higher outpatient and prescription costs. For annual healthcare costs for antiviral treatment options for HBV patients in Turkey, after adjusting for age, gender, region and comorbid condition differences, oral antiviral treatment is more costly than pegylated interferon treatment.

Abstract
This study aimed to estimate and identify determinants of direct medical costs associated with rheumatoid arthritis (RA) in Turkey using nationwide real-world data. Using the Turkish National Health Insurance Database (2009-2011), RA patients (ages 18-99) were identified using International Classification of Disease Tenth Revision Clinical Modification (ICD-10-CM) codes. Patients were required to have two RA diagnoses at least 60 days apart and were grouped as prevalent and incident cases. The date of the first RA claim was identified for each patient and designated as the index date. Total healthcare costs were examined over the 12-month period following the index date. Descriptive and multivariate analyses are provided. Generalized linear models were used to calculate expected annual costs for incident and prevalent RA patients after controlling for age, gender, region, comorbid conditions and medication. A total of 2,613 patients met all inclusion criteria (693 incident; 1,920 prevalent patients). Prevalent patients were older, less likely to reside in the Marmara region, had higher comorbidity index scores and were more likely to use non-steroidal anti-inflammatory drugs, biologics and disease-modifying anti-rheumatic drugs relative to incident patients. Average direct annual costs were <euro>2,000 [(<euro>1,750, <euro>2,247) 95 % CI] for incident cases and <euro>2,385 [(<euro>2,224, <euro>2,545) 95 % CI] for prevalent cases, most due to pharmacy costs (73 % for incident cases, 60 % for prevalent cases). For incident and prevalent cases, a significant portion of inpatient and outpatient costs were due to physician costs (31 % for incident cases, 40 % for prevalent cases). Although the costs were not significantly different in terms of age or region, prior comorbid conditions and medication use significantly affected the cost estimation. RA total annual costs were found to be lower in Turkey, relative to estimates in Europe. The significant portion of the annual costs was due to pharmaceutical expenditures. Comparative effectiveness analysis may be useful to decrease RA-related pharmacy costs.
