Economic evaluation of a trial exploring the effects of a web-based support tool for parents of children with juvenile idiopathic arthritis.

To explore the cost-effectiveness of a web-based support tool for parents of children with Juvenile idiopathic arthritis. A multi-centred randomized controlled trial was conducted in paediatric rheumatology centres in England. The WebParC intervention consisted of online information about JIA and its treatment and a toolkit using cognitive-behavioural therapy principles to support parents manage their child's JIA. An economic evaluation was performed alongside the trial involving 220 parents. The primary outcome was the self-report Pediatric Inventory for Parents measure of illness-related parenting stress, with two dimensions: difficulty and frequency. These measures along with costs were assessed post intervention at 4 and 12 months. Costs were calculated for healthcare usage using a UK NHS economic perspective. Data was collected and analysed on the impact of caring costs on families. Uncertainty around cost-effectiveness was explored using bootstrapping and cost-effectiveness acceptability curves. The intervention arm showed improved average Pediatric Inventory for Parents scores for the dimensions of frequency and difficulty, of 1.5 and 3.6 respectively at 4 months and 0.35 and 0.39 at 12 months, representing improved PIP scores for the intervention arm. At both 4 and 12 month follow-up, the average total cost per case was higher in the control group when compared with the intervention arm with mean differences of £360 (95% CI £29.6 to £691) at 4 months and £203 (95% CI £16 to £390) at 12 months. The probability of the intervention being cost-effective ranged between 49% and 54%. The WebParC intervention led to reductions in primary and secondary healthcare resource use and costs at 4 and 12 months. The intervention demonstrated particular savings for rheumatology services at both follow-ups. Future economies of scale could be realised by health providers with increased opportunities for cost-effectiveness over time. ISRCTN, ISRCTN13159730.

Incidence and Costs of Clinically Significant Events with Systemic Therapy in Patients with Unresectable Hepatocellular Carcinoma: A Retrospective Cohort Study.

Systemic therapies have been associated with clinically significant events (CSEs) in patients with unresectable hepatocellular carcinoma (uHCC). We evaluated the incidence of CSEs (bleeding, clotting, encephalopathy, and portal hypertension), and their impact on healthcare resource utilization (HCRU) and costs, in patients with uHCC treated with first-line (1L) atezolizumab plus bevacizumab (A + B), lenvatinib (LEN), or sorafenib (SOR) in the USA. A retrospective cohort study was performed using medical/pharmacy claims from Optum® Clinformatics® Data Mart. Patients diagnosed with HCC who initiated 1L A + B between June 01, 2020 and December 31, 2020 or LEN/SOR between January 01, 2016 and May31, 2020 were included. Outcomes included incidence rates of CSEs, HCRU, and costs. Subgroup analysis was performed in patients with no CSEs or ≥ 1 CSE. In total, 1379 patients were selected (A + B, n = 271; LEN, n = 217; SOR, n = 891). Clotting (incidence rate per 100 patient-years [PY] 94.9) and bleeding (88.1 per 100 PY) were the most common CSEs in the A + B cohort. The most common CSEs in the LEN cohort were clotting (78.6per 100 PY) and encephalopathy (66.3 per 100 PY). Encephalopathy (73.0per 100 PY) and portal hypertension (72.3 per 100 PY) were the most common CSEs in the SOR cohort. Mean total all-cause healthcare costs per patient per month (PPPM) were $32,742, $35,623, and $29,173 in the A + B, LEN, and SOR cohorts, respectively. Mean total all-cause healthcare costs PPPM were higher in patients who had ≥ 1 CSE versus those who did not (A + B $34,304 versus $30,889; LEN $39,591 versus $30,621; SOR $31,022 versus $27,003). Despite improved efficacy of 1L systemic therapies, CSEs remain a concern for patients with uHCC, as well as an economic burden to the healthcare system. Newer treatments that reduce the risk of CSEs, while improving long-term survival in patients with uHCC, are warranted.

Evidence for clinician underprescription of and patient non-adherence to guideline-recommended cardiovascular medications among adults with peripheral artery disease: protocol for a systematic review and meta-analysis

IntroductionInternational guidelines recommend that adults with peripheral artery disease (PAD) be prescribed antiplatelet, statin and antihypertensive medications. However, it is unclear how often people with PAD are underprescribed these drugs,...

Incidence, Healthcare Resource Use and Costs Associated With Incisional Hernia Repair.

Background: Incisional hernia (IH) is a common complication of abdominal surgery affecting between 12.8% and 30% of patients. In spite of this, rates of IH repair remain low, at around 5% in the literature. We aimed to assess the rate of IH repair in the UK across surgical specialties and the cost burden associated with IH repair. Methods: This is a retrospective observational study of patients undergoing abdominal surgery in England between 2012 and 2022 using the Hospital Episode Statistics (HES) database. Index abdominal surgery was identified between March 2014 and March 2017. Diagnostic and surgical procedure codes were used to identify pre-operative risk factors, index surgeries, IH repair and healthcare contact. Healthcare resource use (HCRU) costs were derived for index surgery and all post-index, non-elective inpatient admissions and outpatient visits using Healthcare Resource Group (HRG) codes within HES. Results: Of 297,134 patients undergoing abdominal surgery, 5.1% (n = 15,138) subsequently underwent incisional hernia repair. By specialty, rates were higher in Colorectal (10.0%), followed by Hepatobiliary (8.2%), Transplant (6.8%), Urological (4.0%), Bariatric (3.5%), Vascular (3.2%) and Gynaecological (2.6%) surgery. Patients undergoing IH repair had more healthcare contacts, longer length of inpatient stays and more A+E visits vs. those with no IH repair post index surgery (83% ≥ 1 A+E visit vs. 69%), as well as higher rates of referral to mental health services (19.8% vs. 11.5%). IH repair was associated with an average HCRU cost of £23,148 compared to £12,321 in patients with no IH repair. Conclusion: Patients undergoing IH repair have a greater morbidity than those not undergoing repair, shown by higher HCRU and more healthcare contacts. Despite this, rates of surgery for IH are low, suggesting that most patients with hernias are not undergoing repair. Emphasis must be placed squarely on primary prevention, rather than cure.

Characterizing the real-world economic burden of metastatic castration-sensitive prostate cancer in the United States

Aims To describe healthcare resource utilization (HRU) and costs of patients with metastatic castration-sensitive prostate cancer (mCSPC). Methods Linked data from Flatiron Metastatic PC Core Registry and Komodo’s Healthcare Map were evaluated (01/2016-12/2021). Patients with chart-confirmed diagnoses for metastatic PC without confirmed castration resistance in Flatiron who initiated androgen deprivation therapy (ADT) monotherapy or advanced therapy for mCSPC in 2017 or later (index date) with a corresponding pharmacy or medical claim in Komodo Health were included. Advanced therapies considered were androgen-receptor signaling inhibitors, chemotherapies, estrogens, immunotherapies, poly ADP-ribose polymerase inhibitors, and radiopharmaceuticals. Patients with <12 months of continuous insurance eligibility before index were excluded. Per-patient-per-month (PPPM) all-cause and PC-related HRU and costs (medical and pharmacy; from a payer’s perspective in 2022 $USD) were described in the 12-month baseline period and follow-up period (from the index date to castration resistance, end of continuous insurance eligibility, end of data availability, or death). Results Of 871 patients included (mean age: 70.6 years), 52% initiated ADT monotherapy as their index treatment without documented advanced therapy use. During baseline, 31% of patients had a PC-related inpatient admission and 94% had a PC-related outpatient visit; mean all-cause costs were $2551 PPPM and PC-related costs were $839 PPPM with $787 PPPM attributable to medical costs. Patients had a mean follow-up of 15 months, during which 38% had a PC-related inpatient admission and 98% had a PC-related outpatient visit; mean all-cause costs were $5950 PPPM with PC-related total costs of $4363 PPPM, including medical costs of $2012 PPPM. Limitations All analyses were descriptive; statistical testing was not performed. Treatment effectiveness and clinical outcomes were not assessed. Conclusion This real-world study demonstrated a significant economic burden in mCSPC patients, and a propensity to use ADT monotherapy in clinical practice despite the availability and guideline recommendations of advanced life-prolonging therapies.

Cost-Effectiveness Evaluation of Oral CGRP Antagonists, Atogepant and Rimegepant, for the Preventative Treatment of Episodic Migraine: Results from a US Societal Perspective Model.

Two oral calcitonin gene-related peptide (CGRP) antagonists, atogepant and rimegepant, were approved in 2021 for the preventive treatment of episodic migraine (EM), yet no formal cost-effectiveness analysis has been published. The objective of this study was to evaluate the cost-effectiveness of atogepant 60 mg and rimegepant 75 mg compared with placebo. A decision tree model was constructed over a 1-year time horizon from a US societal perspective. Patient cohorts were simulated using baseline and change from baseline monthly migraine days (MMDs) reported in the trials to incorporate responder rates and within patient response into the model. Due to heterogeneity between the trial populations, each medication was compared with its respective trial's placebo group. Direct healthcare resource costs, productivity costs, acute medication costs, and quality-of-life values were obtained from the literature. The atogepant cohort experienced an incremental increase in healthcare plus productivity costs of $11,978 when compared with placebo, with a gain of 0.026 quality-adjusted life-years (QALYs). This yielded an incremental cost-effectiveness ratio (ICER) of more than $450,000/QALY. The rimegepant cohort experienced an incremental increase of $21,692 when compared with placebo, with a gain of 0.024 QALYs. This yields an ICER of more than $890,000/QALY when comparing rimegepant with placebo. Cost savings between atogepant and atogepant placebo were greatest with respect to acute medication costs at $735 of savings over 1 year, followed by savings of $135 for healthcare resource utilization and $34 for productivity costs. A similar relationship was seen between rimegepant and rimegepant placebo. One-way deterministic sensitivity analysis found that monthly acquisition costs of atogepant and rimegepant had the largest impact on the ICER, respectively. Atogepant and rimegepant were both unable to meet generally accepted cost-effectiveness thresholds < 150,0000/QALY. Additional studies are needed to better guide decision making regarding oral CGRPs' place in therapy.

Oncology and Palliative Care Integration Model: A Cost Analysis Study in a Brazilian Hospital Setting.

Background: In 2019, the São Paulo State Cancer Institute (ICESP) implemented a novel model integrating Oncology with Palliative Care specialists. We evaluated the impact of this model on healthcare resource utilization and costs. Methods: We analyzed data from all patients who passed away in February (1month prior to implementation) and November (8months after model implementation group) at ICESP, Brazil. Healthcare utilization data, including emergency department visits, hospital and intensive care unit admissions, chemotherapy, and radiotherapy use, were retrieved from Electronic Medical Records. Unit cost values were obtained from the administrative database. Results: A total of 198 patients who died in February and 196 in November were included in the analysis. Groups exhibited similarities in sex, age, ECOG, cancer type, previous outpatient palliative care consultations, and place of death (ward: 56.6% pre-intervention, 50% post-intervention). The mean cost per patient was US$13,226.29 pre-intervention and US$11,445.82 post-intervention (P = .007). Statistically significant differences were noted in days hospitalized in the surgical ward (227 vs 115), emergency department visits (233 vs 45), chemotherapy sessions (140 vs 26), and radiotherapy sessions (146 vs 10). Excluding outpatient treatments, the total costs for chemotherapy and radiotherapy in the last 30days of life were US$16,924.45 pre-intervention and US$7851.65 post-intervention. Reductions were more pronounced in patients with ECOG 3-4 (P = .039). Conclusion: Our data suggests that the integration model was associated with a reduction in potentially inappropriate treatments during the last month of life, leading to decreased healthcare utilization and costs.

Clinical and Economic Burden of Antibiotic Use Among Pediatric Patients With Varicella Infection in the Outpatient Setting: A Retrospective Cohort Analysis of Real-world Data in France.

Varicella infects 90% of children before age 9. Though varicella is self-limiting, its complications may require antibiotics, though how antibiotics are utilized for varicella in France is not well known. This study assessed antibiotic use and costs associated with varicella and its complications in pediatric patients managed in the outpatient setting in France. A retrospective cohort study using the Cegedim Strategic Data-Longitudinal Patient Database, an electronic medical record database from general practitioners and office-based specialists in France, was conducted. Children <18 years old diagnosed with varicella between January 2014 and December 2018 with 3-month follow-up available were included. We used descriptive analysis to assess varicella-related complications, medication use, healthcare resource utilization and costs. Overall, 48,027 patients were diagnosed with varicella; 15.3% (n = 7369) had ≥1 varicella-related complication. Antibiotics were prescribed in up to 25.1% (n = 12,045/48,027) of cases with greater use in patients with complications (68.1%, n = 5018/7369) compared with those without (17.3%, n = 7027/40,658). Mean medication and outpatient varicella-related costs were €32.82 per patient with medications costing a mean of €5.84 per patient; antibiotics contributed ~23% to total costs annually. This study showed high antibiotic use for the management of varicella and its complications. A universal varicella vaccination program could be considered to alleviate complications and associated costs in France.

Healthcare Resource Utilization and Costs in an At-Risk Population With Diabetic Retinopathy.

Several investigators have suggested the cost-effectiveness of earlier screening, management of risk factors, and early treatment for diabetic retinopathy (DR). We aimed to evaluate the extent of health care utilization and cost of delayed care by insurance type in a vulnerable patient population. A retrospective analysis of patients with DR was conducted using electronic medical record (EMR) data from January 2014 to December 2020 at Denver Health Medical Center, a safety net institution. Patients were classified by disease severity and insurance status. DR-specific costs were assessed via Current Procedural Terminology (CPT) codes over a 24-month follow-up period. Among the 313 patients, a higher proportion of non-English speaking patients were uninsured. Rates of proliferative DR at presentation differed across insurance groups (62% of uninsured, 42% of discount plan, and 33% of Medicare/Medicaid, P = 0.016). There was a significant difference in the total median cost between discount plan patients ($1258, interquartile range [IQR] = $0 - $5901) and both Medicare patients ($751, IQR = $0, $7148, P = 0.037) and Medicaid patients ($593, IQR = $0 - $6299, P = 0.025). There were higher rates of proliferative DR at presentation among the uninsured and discount plan patients and greater total median cost in discount plan patients compared to Medicare or Medicaid. These findings prioritize mitigating gaps in insurance coverage and barriers to preventative care among vulnerable populations. Advanced diabetic disease and increased downstream health care utilization and cost vary across insurance type, suggesting improved access to preventative care is needed in these specific at-risk populations.

Treatment patterns and healthcare resource utilization in patients with metastatic hormone-sensitive prostate cancer and nonmetastatic castration-resistant prostate cancer in China: a real-world observational study

Aim This study assessed the treatment patterns, healthcare resource utilization (HRU), costs, and annual prevalence and incidence of metastatic hormone-sensitive prostate cancer (mHSPC) and nonmetastatic castration-resistant prostate cancer (nmCRPC) in China. Methods A retrospective study was conducted using electronic medical records (EMR) of patients with prostate cancer from three tertiary-care hospitals in China between January 2014 and March 2021. Descriptive statistics were used to analyze study outcomes. Results In total, 1086 patients with mHSPC and 679 patients with nmCRPC were included. From 2015 to 2020, the annual percentage of prevalent and incident cases of mHSPC decreased from 22.4% to 20.0% and 11.1% to 6.9%, respectively; for nmCRPC, these increased from 3.8% to 13.6% and 3.3% to 8.4%. Androgen-deprivation therapy and first-generation antiandrogens (bicalutamide or flutamide) were the most frequently prescribed prostate cancer–related medications at baseline and follow-up in patients with mHSPC. Bicalutamide was the most frequently prescribed prostate cancer–related medication during follow-up in patients with nmCRPC. For mHSPC, inpatient admission costs were the highest, with the median (interquartile range) costs per person-month being USD 403.00 (USD 85.50–1226.20), whereas outpatient visit costs were the highest for nmCRPC (USD 372.60 [USD 139.50–818.50]). Limitations EMR-based study design did not capture treatment patterns, HRU and associated costs, and healthcare encounters that occurred outside of participating hospitals, which could have led to underestimation of the true disease burden. Conclusions A contrasting trend of a decline in the prevalence and incidence of mHSPC and an increase in these for nmCRPC was observed between 2015 and 2020 in China. Androgen-deprivation therapy and first-generation antiandrogens were the most frequently prescribed prostate cancer–related medications. Healthcare resource utilization was driven by inpatient costs in mHSPC and outpatient costs in nmCRPC.

Higher healthcare resource utilization and costs among patients with idiopathic hypersomnia compared with matched controls

Higher healthcare resource utilization and costs among patients with idiopathic hypersomnia compared with matched controls

Economic analyses in cardiac electrophysiology: from clinical efficacy to cost utility.

Cardiac electrophysiology is an evolving field that relies heavily on costly device- and catheter-based technologies. An increasing number of patients with heart rhythm disorders are becoming eligible for cardiac interventions, not least due to the rising prevalence of atrial fibrillation and increased longevity in the population. Meanwhile, the expansive costs of healthcare face finite societal resources, and a cost-conscious approach to new technologies is critical. Cost-effectiveness analyses support rational decision-making in healthcare by evaluating the ratio of healthcare costs to health benefits for competing therapies. They may, however, be subject to significant uncertainty and bias. This paper aims to introduce the basic concepts, framework, and limitations of cost-effectiveness analyses to clinicians including recent examples from clinical electrophysiology and device therapy.

Treatment Patterns, Healthcare Resource Utilization, and Costs of Patients With Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma in the US.

Chronic lymphocytic leukemia (CLL) is the most common type of leukemia among US adults and has experienced a rapidly evolving treatment landscape; yet current data on treatment patterns in clinical practice and economic burden are limited. This study aimed to provide an up-to-date description of real-world characteristics, treatments, and costs of patients with CLL or small lymphocytic lymphoma (SLL). Using retrospective data from the Optum Clinformatics DataMart database (January 2013 to December 2021), adults with diagnosis codes for CLL/SLL on two different dates were selected. An adapted algorithm identified lines of therapy (LOT). Treatment patterns were stratified by the index year pre- and post-2018. Healthcare resource utilization and costs were evaluated per patient-years. A total of 18 418 patients with CLL/SLL were identified, 5226 patients (28%) were treated with ≥1 LOT and 1728 (9%) with ≥2 LOT. Among patients diagnosed with CLL in 2014-2017 and ≥1 LOT (N = 2585), 42% used targeted therapy and 30% used chemoimmunotherapy in first line (1L). The corresponding proportions of patients diagnosed with CLL in 2018-2021 (N = 2641) were 54% and 16%, respectively. Total costs were numerically 3.5 times higher and 4.9 times higher compared with baseline costs among patients treated with 1L+ and 3L+, respectively. This study documented the real-world change in CLL treatment landscape and the substantial economic burden of patients with CLL/SLL. Specifically, targeted therapies were increasingly used as 1L treatments and they were part of more than half of 1L regimens in recent years (2018-2021).

Real world treatment patterns, healthcare resource use and costs in patients with advanced or metastatic non-small cell lung cancer by EGFR mutation type

Aims This study described treatment patterns, healthcare resource utilization (HRU) and costs among advanced or metastatic non-small cell lung cancer (a/mNSCLC) patients with different epidermal growth factor receptor (EGFR) mutation types. Materials and methods This retrospective study leveraged NeoGenomics NeoNucleus linked with IQVIA PharMetrics Plus between 01 January 2016 to 30 April 2021 (study period). Patients with evidence of a/mNSCLC between 01 July 2016 to 31 March 2021 (selection window) with EGFR test results indicating exon 19 deletion (exon19del), exon 21 L858R (L858R), or exon 20 insertion (exon20i) mutations were included; date of first observed evidence of a/mNSCLC was the index date. Treatment patterns, all-cause HRU and costs during ≥1 month follow-up were reported for each cohort (exon19del, L858R, and exon20i). Results A total of 106 exon19del, 75 L858R, and 13 exon20i patients met the study criteria. The prevalence of hospitalization was highest in the exon20i cohort (76.9%), followed by L858R (62.7%) and exon19del (55.7%) cohorts. A higher proportion of patients had evidence of hospice/end-of-life care in the exon20i (30.8%) and L858R (29.3%) cohorts relative to the exon19del cohort (22.6%). The exon20i cohort had higher median total healthcare costs per patient per month ($27,069) relative to exon19del ($17,482) and L858R ($17,763). EGFR tyrosine kinase inhibitors (TKI) were the most frequently observed treatment type for exon19del and L858R cohorts, while chemotherapy was the most observed treatment in exon20i cohort. Limitations The sample size for the study cohorts was small, thus no statistical comparisons were conducted. Conclusions This is one of the first real-world studies to describe HRU and costs among a/mNSCLC patients by specific EGFR mutation type. HRU and costs varied between EGFR mutation types and were highest among exon20i cohort, potentially reflecting higher disease burden and unmet need among patients with this mutation.

P912 A Real-World Evidence Study of Dose Escalation and associated costs of advanced therapies for Ulcerative Colitis in France and United Kingdom

Abstract Background Dose escalation to optimize advanced therapies is common practice in ulcerative colitis (UC) to avoid intra-class or inter-class drug switching and maintain clinical response. Dose escalation also has impact on healthcare resource utilization (HRU) and costs. However, there are limited data available on real-life dose-escalation. Study aim was to understand real-world dose escalation/de-escalation UC advanced therapy drugs patterns in two European countries (France, United Kingdom [UK]). Methods This retrospective study analysed data from the THIN®/CEGEDIM database to identify adult patients with moderate-to-severe UC who were naïve to advanced UC therapies or had not received any of the UC advanced therapy drugs of interest (adalimumab [ADA], golimumab [GOL], infliximab [INF], tofacitinib [TOF], ustekinumab [UST], or vedolizumab [VED]) for at least 12 months prior first prescription (and/or dispensation for France) between January 2017 and February 2022. A dose increase of ≥20% during the maintenance period compared to lowest Summary of Product Characteristics recommended dose was considered dose escalation. Proportions of patients with dose escalation after maintenance date were estimated using Kaplan-Meier (KM) survival analyses. Clinical response (defined as absence of: UC-related hospitalization or colectomy, treatment switch or addition of another UC advanced drug, systemic/rectal corticosteroids exposure), and direct (consultations, hospitalisations, diagnostic tests, UC drugs, complementary therapy) and indirect costs related to UC by treatment cohort were also analysed. Results 1663 patients fulfilled the selection criteria, of whom 619 had information on dose patterns. Overall, 89% of patients (range 33% [INF] to 100% [GOL, TOF, and UST]) had dose escalation within the first 24 months after start of maintenance, with a median % dose increase ranging from +15% [VED] to +198% [GOL] (Table). Median (95% CI) time to first dose escalation was 2.1 (1.8-2.4) months (range 0.7 [UST] to 4.6 [VED]). Clinical response ranged from 56.3% (ADA) to 77.0% (INF). Direct annual HRU costs related to UC ranged from 3,085 (INF) to 16,527 (UST) EUR in France and from 1,857 (INF) to 4,104 (VED) GBP in the UK. Mean direct HRU costs in France were 25% higher in escalated patients compared to de-escalated patients (range: +4.2% GOL to +61.9% UST). Conclusion Dose escalation of advanced therapies for UC is a common strategy to avoid treatment-switching. Despite dose escalations and their cost to the system, a proportion of patients fail to achieve clinical response, highlighting the need for more efficacious and durable treatments for patients with moderate-to-severe UC.

Healthcare Resource Use and Costs Among Individuals with Vitiligo and Psychosocial Comorbidities: Retrospective Analysis of an Insured US Population.

This study aimed to describe healthcare resource utilization and costs among individuals with vitiligo who were diagnosed with ≥1 psychosocial comorbidity, using data from US claims databases. A retrospective, observational cohort analysis of the IBM MarketScan Commercial and Medicare supplemental claims databases for US individuals with vitiligo aged ≥12 years and a first vitiligo claim between January 1 and December 31, 2018, was undertaken to assess psychosocial burden, including mental and behavioral health comorbidities. Of the 12,427 individuals included in the analysis, nearly 1 in 4 (23.5%) who had vitiligo were also diagnosed with ≥1 psychosocial comorbidity. A greater percentage of these individuals versus those who were not diagnosed with a psychosocial comorbidity had a vitiligo-related prescription claim (50.2% vs 45.4%; P<0.0001), especially for oral corticosteroids (25.4% vs 16.6%; P<0.0001) and low-potency topical corticosteroids (9.0% vs 7.6%; P<0.05). Total vitiligo-related healthcare resource utilization and costs were consistent among individuals with and without psychosocial comorbidity despite significantly (P<0.05) higher vitiligo-related ER visit utilization and expenditure among those with psychosocial comorbidity. Furthermore, individuals diagnosed with vitiligo and ≥1 psychosocial comorbidity had significantly (P<0.0001) greater utilization of all-cause mean prescription claims (25.0 vs 12.8), outpatient services (other than physician and ER visits: 19.5 vs 11.3), outpatient physician visits (10.1 vs 6.4), inpatient stays (0.6 vs 0.1), and ER visits (0.4 vs 0.2) and incurred significantly higher mean (SD) direct medical expenditures ($18,804 [$46,621] vs $9833 [$29,094] per patient per year; P<0.0001). Individuals with vitiligo who were diagnosed with ≥1 psychosocial comorbidity incurred greater total all-cause but not vitiligo-related healthcare resource utilization and expenditures than those without diagnosis of psychosocial comorbidities. Identification of psychosocial comorbidities in individuals with vitiligo may be important for multidisciplinary management of vitiligo to reduce overall burden for individuals with vitiligo.

Impact of Pre-existing Type 2 Diabetes Mellitus and Cardiovascular Disease on Healthcare Resource Utilization and Costs in Patients With COVID-19.

Background: The economic burden associated with type 2 diabetes mellitus (T2DM) and concurrent cardiovascular disease (CVD) among patients with COVID-19 is unclear. Objective: We compared healthcare resource utilization (HCRU) and costs in patients with COVID-19 and T2DM and CVD (T2DM + CVD), T2DM only, or neither T2DM nor CVD (T2DM/CVD). Methods: A retrospective observational study in COVID-19 patients using data from the Healthcare Integrated Research Database (HIRD®) was conducted. Patients with COVID-19 were identified between March 1, 2020, and May 31, 2021, and followed from first diagnosis or positive lab test to the end of health plan enrollment, end of study period, or death. Patients were assigned one of 3 cohorts: pre-existing T2DM+CVD, T2DM only, or neither T2DM/CVD. Propensity score matching and multivariable analyses were performed to control for differences in baseline characteristics. Study outcomes included all-cause and COVID-19-related HCRU and costs. Results: In all, 321 232 COVID-19 patients were identified (21 651 with T2DM + CVD, 28 184 with T2DM only, and 271 397 with neither T2DM/CVD). After matching, 6967 patients were in each group. Before matching, 46.0% of patients in the T2DM + CVD cohort were hospitalized for any cause, compared with 18.0% in the T2DM-only cohort and 6.3% in the neither T2DM/CVD cohort; the corresponding values after matching were 34.2%, 26.0%, and 21.2%. The proportion of patients with emergency department visits, telehealth visits, or use of skilled nursing facilities was higher in patients with COVID-19 and T2DM + CVD compared with the other cohorts. Average all-cause costs during follow-up were 7882, and $7277 per-patient-per-month after matching for patients with T2DM + CVD, T2DM-only, and neither T2DM/CVD, respectively. COVID-19-related costs contributed to 78%, 75%, and 64% of the overall costs, respectively. The multivariable model showed that per-patient-per-month all-cause costs for T2DM + CVD and T2DM-only were 54% and 21% higher, respectively, than those with neither T2DM/CVD after adjusting for residual confounding. Conclusion: HCRU and costs in patients were incrementally higher with COVID-19 and pre-existing T2DM + CVD compared with those with T2DM-only and neither T2DM/CVD, even after accounting for baseline differences between groups, confirming that pre-existing T2DM + CVD is associated with increased HCRU and costs in COVID-19 patients, highlighting the importance of proactive management.

Healthcare Resource Utilization Associated with Intermittent Oral Corticosteroid Prescribing Patterns in Asthma.

Oral corticosteroid (OCS) use for asthma is associated with considerable healthcare resource utilization (HCRU) and costs. However, no study has investigated this in relation to patterns of intermittent OCS prescription. This historical UK cohort study used primary care medical records, linked to Hospital Episode Statistics, from 2008 to 2019, of patients (≥4 years old) with asthma prescribed intermittent OCS. Patients were categorized by OCS prescribing pattern (one-off [single], less frequent [≥90-day gap] and frequent [<90-day gap]) and matched 1:1 (by sex, age and index date) with people never prescribed OCS with/without asthma. HCRU (reported as episodes, except for length of hospital stay [days] and any prescription [records]) and associated costs were compared between intermittent OCS and non-OCS cohorts, and among intermittent OCS prescribing patterns. Of 149,191 eligible patients, 50.3% had one-off, 27.4% less frequent, and 22.3% frequent intermittent OCS prescribing patterns. Annualized non-respiratory HCRU rates were greater in the intermittent OCS versus non-OCS cohorts for GP visits (5.93 vs 4.70 episodes, p < 0.0001), hospital admissions (0.24 vs 0.16 episodes, p < 0.0001), and length of stay (1.87 vs 1.58 days, p < 0.0001). In the intermittent OCS cohort, rates were highest in the frequent prescribing group for GP visits (7.49 episodes; p < 0.0001 vs one-off), length of stay (2.15 days; p < 0.0001) and any prescription including OCS (25.22 prescriptions; p < 0.0001). Mean per-patient non-respiratory related and all-cause HCRU-related costs were higher with intermittent OCS than no OCS (£3902 vs £2722 and £8623 vs £4929, respectively), as were mean annualized costs (£565 vs £313 and £1526 vs £634, respectively). A dose-response relationship existed; HCRU-related costs were highest in the frequent prescribing cohort (p < 0.0001). Intermittent OCS use and more frequent intermittent OCS prescription patterns were associated with increased HCRU and associated costs. Improved asthma management is needed to reduce reliance on intermittent OCS in primary care.

Adverse events and costs among non-metastatic castration-resistant prostate cancer patients

Background Limited real-world evidence exists on the economic burden of adverse events (AEs) to the healthcare system among patients with non-metastatic castration-resistant prostate cancer (nmCRPC) treated with second-generation androgen receptor antagonists (ARAs). Current data is needed to understand real-world clinical event rates among ARAs and the cost of these events. Objectives Describe the incidence of non-central nervous system (CNS)-related AEs and CNS-related AEs among nmCRPC patients treated in the United States with second-generation ARAs (apalutamide and enzalutamide) and evaluate healthcare resource utilization (HCRU) and costs for these patients. Methods and study design This was a retrospective observational cohort study using claims data from Optum Clinformatics Data Mart to identify adult males with prostate cancer, castration, no metastases, and >1 claim for apalutamide or enzalutamide. The study was conducted from January 2017 to March 2020, with a patient index identification period from January 2018 to December 2019. AEs were classified as CNS-related or non-CNS-related. Results Of 605 patients (156 apalutamide and 449 enzalutamide), most were ≥65 years (94%) and had ≥1 non-CNS-related AE (55%). Many had ≥1 CNS-related AE (32%). Pain (12%) and arthralgia (11%) were the most frequently reported non-CNS-related AEs. Fatigue/asthenia (14%) and dizziness (7%) were the most frequently reported CNS-related AEs. Among patients with versus without non-CNS-related AEs, 34% versus 8% had emergency room (ER) events, and 25% versus 2% had inpatient events. Among patients with versus without CNS-related AEs, 41% versus 14% had ER events, and 38% versus 4% had inpatient events. Adjusted per-patient per-year cost (in 2020 USD) differences were significant between patients with and without non-CNS-related AEs ($30,765, p = 0.0018) and between patients with and without CNS-related AEs ($40,689, p = 0.0017). Conclusion There is significant HCRU and cost burden among nmCRPC patients treated with ARAs developing AEs, highlighting the need for treatments with improved tolerability. Additional studies are warranted to include recently approved agents.
