Incremental health care expenditures for non-Hodgkin lymphoma in comparison with other cancers: Analysis of national survey data.

BACKGROUND: Non-Hodgkin lymphoma (NHL) is among the most common cancers in the United States, with an estimated annual incidence of more than 80,000 and a high survival rate. However, limited national data exist regarding the health care burden of NHL. OBJECTIVE: To evaluate the incremental health care expenditures among patients with NHL using the Medical Expenditure Panel Survey (MEPS) data compared with patients with other cancers. METHODS: This observational cross-sectional study included all patients with NHL (≥ 18 years) and all individuals diagnosed with other cancers from the MEPS 2014-2019. The components of health care expenditures included hospital inpatient care, office-based visits, outpatient care, emergency department, prescription medications, dental, home health, and other expenditures. Patients with NHL and those diagnosed with other cancers were identified from the full-year consolidated MEPS Household Component 2014-2019. Descriptive weighted analysis was used to compare the health care expenditure components between individuals with NHL and all other cancers. A 2-part model using probit and generalized linear models with a log link function was used to estimate the incremental increase in total health care expenditures for NHL compared with all other cancers. RESULTS: According to the MEPS, there were 0.74 million patients with NHL (95% CI = 0.62-0.86) and 27.91 million patients with other cancers (95% CI = 26.69-29.13) annually. Most of the patients with NHL were White (78.36%), male (60.67%), and older than 65 years (45.8%). The unadjusted analysis indicated a total annual expenditure of $21,698 (95% CI = $16,752-$26,645) for NHL, which was significantly higher than the annual expenditure for patients with other cancers ($15,029 [95% CI = $14,476-$15,582]). Most of the total health expenditure of both the NHL group and the other cancers group was distributed in 3 categories of hospital inpatient care (29.15% vs 26.29%), office-based visits (28.10% vs 25.08%), and prescription medications (19.03% vs 22.57%). Based on the 2-part model adjusted for all covariates, the annual health care expenditure for NHL was $7,284 (95% CI = $1,432-$13,135), higher than the expenditure of patients diagnosed with all other cancers. Among the health care expenditure components, the office-based visits were $2,641 higher for patients with NHL compared with the other cancers group (95% CI = $1,129-$4,153). CONCLUSIONS: The economic burden of NHL is higher compared with other cancers. Most of the NHL expenditures were attributable to hospital inpatient services and office-based visits. The study findings can inform value-based care considerations because of a better understanding of utilization and care patterns for NHL.

Association of cash payment with intensity of opioid prescriptions.

BACKGROUND: It is difficult to track use and outcomes in patients who pay cash for their prescriptions at the pharmacy. In Texas, 14% of all opioid prescriptions are paid with cash, often by uninsured patients and pharmacy shoppers. OBJECTIVE: To evaluate the association of cash payment with intensity of opioid prescriptions. METHODS: Using a prescription drug monitoring program and the U.S. Census data for the 2019 calendar year, this cross-sectional descriptive study analyzed more than 4 million opioid prescriptions in Texas residents aged 18-64 years. The payment type was coded as insurance if the prescription was paid in whole or in part by a health plan and as cash otherwise. Daily morphine milligram equivalent (MME) dose was used to compare the intensity of opioid prescriptions. The association of uninsured rates with mean daily MME and the number of opioid prescriptions paid with cash per 100,000 persons were assessed at a county level. RESULTS: Cash payment was associated with 30% higher mean daily MME (59 vs. 45; P < 0.001) than insurance payment. This difference was driven by the prescriptions for patients aged 25-34 years and from the highest decile of prescribers based on the percentage of opioid prescriptions paid by cash. For instance, cash payment was associated with 82% higher mean daily MME (91 vs. 50; P < 0.001) when patients aged 25-34 years obtained their prescriptions from the highest decile of prescribers. At a county level, uninsured rates were not associated with mean daily MMEs or the number of opioid prescriptions paid with cash. CONCLUSION: Cash payment was associated with a higher intensity of opioid prescriptions, mirroring the rates of drug overdose deaths across the patient age groups. Further research and policy actions need to address unmet pain management needs in uninsured patients and potential pharmacy shopping with cash payment and fraudulent identifications.

Medical insurance and physician-induced demand in China: the case of hemorrhoid treatments.

In October 2015, the Guangdong government of China enacted a so-called unified medical insurance payment for patients residing in Guangdong province, which fundamentally simplifies reimbursement procedures of medical insurance for the involved cross-city in-patients. Using a unique confidential dataset from 2013 to 2018 on hemorrhoid treatments at a renowned hospital in Guangzhou, the provincial capital of Guangdong, and exploiting difference-in-differences estimations based on the abovementioned policy, we document that the physicians' incentives are a negative externality of the full medical insurance policy for cross-city in-patients and account for a 49% probability increase in improper treatments; and neither increasing the communication between physicians and patients nor enhancing the education level of patients reduces the physician-induced demand for improper treatments. A series of robustness tests indicate our findings are solid. In summary, we highlight the substantial roles of medical insurance as a driver of physician-induced demand in an emerging economy such as China.

Time to Next Treatment, Health Care Resource Utilization, and Costs Associated with Ibrutinib Use Among U.S. Veterans with Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma: A Real-World Retrospective Analysis.

BACKGROUND: Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is the most common adult leukemia, accounting for ≈ 37% of all leukemias in the United States. Limited real-word evidence is available on the outcomes of ibrutinib use among previously untreated patients in the U.S. Veterans Health Administration (VHA) population diagnosed with CLL/SLL. OBJECTIVES: To (a) evaluate time to next treatment (TTNT) among U.S. veterans with CLL/SLL who initiated ibrutinib versus chemoimmunotherapy (CIT) in first line (1L) and 1L ibrutinib versus ibrutinib in later lines (2L+) and (b) compare health care resource utilization (HRU) and costs between the 1L ibrutinib and CIT cohorts. METHODS: Adults with CLL/SLL and claims for 1L single-agent ibrutinib or CIT (index date = first prescription claim date) were included from Veterans Health Administration Data (April 1, 2013-March 31, 2018). A subset of the CIT 1L cohort with evidence of ibrutinib in 2L/3L was defined as the ibrutinib 2L+ cohort. Kaplan-Meier curves and Cox proportional hazard models were used to evaluate TTNT, and generalized linear models were used to determine all-cause per patient per month (PPPM) HRU and costs during 1L among propensity score-matched (PSM) cohorts. RESULTS: After PSM, 614 patients were included in each of the 1L ibrutinib and 1L CIT cohorts, and 149 were included in each of the 1L ibrutinib and 2L+ ibrutinib cohorts. The 1L ibrutinib cohort had significantly longer TTNT compared with each of the 1L CIT and 2L+ ibrutinib cohorts (P <0.0001 and P =0.0001, respectively) and was less likely to have a next line of treatment than the CIT 1L cohort (HR = 0.52; 95% CI = 0.42-0.65; P < 0.0001) and the 2L+ ibrutinib cohort (HR = 0.39; 95% CI = 0.22-0.69; P = 0.0012). The 1L ibrutinib cohort had significantly fewer inpatient visits (rate ratio [RR] = 0.38; 95% CI = 0.28-0.52; P ≤ 0.05) and outpatient visits PPPM (RR =0.72; 95% CI = 0.68-0.77; P ≤ 0.5) compared with the CIT 1L cohort. Additionally, the 1L ibrutinib cohort had $7,308 significantly lower monthly medical costs (95% CI = -$9,892 to -$4,895; P ≤ 0.05) versus the 1L CIT cohort, resulting in comparable monthly total health care cost (medical and pharmacy) between real-world 1L patients treated by ibrutinib and CIT (-$2,160; 95% CI = -$4,840-$347; P > 0.05). CONCLUSIONS: These findings demonstrate that among U.S. veterans with CLL/SLL, 1L ibrutinib use was associated with significantly longer TTNT versus that of 1L CIT. Similarly, early treatment with ibrutinib was associated with longer TTNT as compared to ibrutinib use in later lines of therapy. Moreover, 1L ibrutinib was associated with lower HRU and medical costs compared with 1L CIT, completely offsetting the higher pharmacy costs related to 1L ibrutinib treatment.

Real-world adherence and persistence for newly-prescribed HIV treatment: single versus multiple tablet regimen comparison among US medicaid beneficiaries.

BACKGROUND: Once-daily, single-tablet regimens (STRs) have been associated with improved patient outcomes compared to multi-tablet regimens (MTRs). This study evaluated real world adherence and persistence of HIV antiretroviral therapy (ART), comparing STRs and MTRs. METHODS: Adult Medicaid beneficiaries (aged ≥ 18 years) initiating ART with ≥ 2 ART claims during the identification period (January 1, 2015-December 31, 2016) and continuous health plan enrollment for a 12-month baseline period were included. For STRs, the first ART claim date was defined as the index date; for MTRs, the prescription fill claim date for the last drug in the regimen was defined as the index date, and prescription fills were required to occur within a 5-day window. Adherence was assessed in 30-day intervals over a 6-month period, with adherence defined as having less than a 5-day gap between fills. Persistence was evaluated as median number of days on therapy and percent persistence at 12 months. Cox Proportional Hazard models were used to evaluate risk of discontinuation, controlling for baseline and clinical characteristics. RESULTS: A total of 1,744 (STR = 1290; MTR = 454) and 2409 (STR = 1782; MTR = 627) patients newly prescribed ART had available data concerning adherence and persistence, respectively. Average age ranged 40-42 years. The patient population was predominantly male. Adherence assessments showed 22.7% of STR initiators were adherent to their index regimens over a 6-month period compared to 11.7% of MTR initiators. Unadjusted persistence analysis showed 36.3% of STR initiators discontinued first-line therapy compared to 48.8% for MTR initiators over the 2-year study period. Controlling for baseline demographic and clinical characteristics, MTR initiators had a higher risk of treatment discontinuation (hazard ratio [HR] = 1.6, p < 0.0001). Among STRs, compared to the referent elvitegravir(EVG)/cobicistat(COBI)/emtricitabine(FTC)/tenofovir alafenamide(TAF), risk of discontinuation was higher for efavirenz(EFV)/FTC/tenofovir disoproxil fumarate(TDF) (HR = 3.6, p < 0.0001), EVG/COBI/FTC/TDF (HR = 2.8, p < 0.0001), and abacavir (ABC)/lamivudine (3TC)/dolutegravir (DTG) (HR = 1.8, p = 0.004). Among backbones, FTC/TAF was associated with lower risk of discontinuation than FTC/TDF (HR = 4.4, p < 0.0001) and ABC/3TC (HR = 2.2, p < 0.0001). CONCLUSIONS: Among patients newly prescribed ART, STR initiators were significantly less likely to discontinue therapy and had greater adherence and persistence compared to MTR initiators. Regimens containing FTC/TAF as a backbone had higher persistence than those consisting of other backbones.

Adverse event rates and economic burden associated with purine nucleoside analogs in patients with hairy cell leukemia: a US population-retrospective claims analysis.

BACKGROUND: Purine nucleoside analogs (PNAs) are the recommended first-line treatment for patients with hairy cell leukemia (HCL), but they are associated with adverse events (AEs). Due to a lack of real-world evidence regarding AEs that are associated with PNAs, we used commercial data to assess AE rates, AE-related health care resource utilization (HCRU), and costs among PNA-treated patients with HCL. Adults aged ≥18 years with ≥2 claims for HCL ≥30 days apart from 1 January 2006 through 31 December 2015 were included. Included patients had ≥1 claim for HCL therapy (cladribine ± rituximab or pentostatin ± rituximab [index date: first claim date]) and continuous enrollment for a ≥ 6-month baseline and ≥ 12-month follow-up period. Patient sub-cohorts were based on the occurrence of myelosuppression and opportunistic infections (OIs). Generalized linear models were used to compare HCRU and costs. RESULTS: In total, 647 PNA-treated patients were identified (mean age: 57.1 years). Myelosuppression and OI incidence were 461 and 42 per 1000 patient-years, respectively. Adjusted results indicated that those with myelosuppression had higher rates of hospitalization (47.4% vs 12.4%; P < .0001) and incurred higher mean inpatient costs ($23,517 vs $12,729; P = .011) and total costs ($57,325 vs $34,733; P = .001) as compared with those without myelosuppression. Similarly, patients with OIs had higher rates of hospitalization (53.8% vs 30.8%; P = .025) and incurred higher mean inpatient costs ($21,494 vs $11,229; P < .0001) as compared with those without OIs. CONCLUSIONS: PNA therapy is highly effective but associated with significant toxicities that increase costs; these findings indicate a need for therapies with improved toxicity profiles and better risk stratification of patients at risk of developing myelosuppression and OIs.
