Interrupted time series analysis of chronic periodontitis-related procedures before and after the scaling reimbursement policy in Korea.

AIM: To study the use of a quasi-experimental design to assess the effects of scaling reimbursement policies on the incidence of chronic-periodontitis procedures. MATERIALS AND METHODS: Interrupted time series analysis was used to compare the effects before and after policy implementation using data on the number of periodontitis-related procedures from the Korean National Health Insurance Service-National Sample Cohort (n = 740,467) and the Health Screening Cohort (n = 337,904). Periodontitis-related procedures with diagnosis codes were categorized into basic (scaling or root planing), intermediate (subgingival curettage) and advanced (tooth extraction, periodontal flap surgery, bone grafting for alveolar bone defects or guided tissue regeneration). Subjects' demographics and comorbidities were considered. The incidence rate of immediate changes and gradual effects before and after policy implementation was assessed. RESULTS: Following the policy implementation from July 2013, an immediate increase was observed in total and basic procedures. No significant changes were noted in intermediate and advanced procedures initially. A decrease in the slope of intermediate procedures was observed in both databases. Advanced procedures showed varied trends, with no change in the National Sample Cohort but an increase in the Health Screening Cohort, particularly among subjects with comorbidities. CONCLUSIONS: Following the new policy implementation, the number of intermediate procedures decreased while the number of advanced procedures increased, especially among patients with comorbidities. These findings offer valuable insights on policy evaluation.

Insurance Reimbursement for Special Foods and Phenylalanine Levels in Patients With PKU in China.

Importance: Recent changes in China's social medical insurance reimbursement policy have impacted the financial burden of patients with phenylketonuria (PKU) for special foods. However, whether this policy change is associated with their blood phenylalanine (PHE) concentration is unclear. Objective: To investigate the association between the reimbursement policy and blood PHE concentration in patients with PKU. Design, Setting, and Participants: This cohort study measured the blood PHE concentrations of 167 patients with PKU across 4 newborn screening centers in China from January 2018 to December 2021. The reimbursement policy for special foods for patients with PKU at 2 centers was canceled in 2019 and restored from 2020 onwards. In contrast, the other 2 centers consistently implemented the policy. Data were analyzed from September 10 to December 6, 2023. Exposures: The implementation and cancelation of the reimbursement policy for special foods of patients with PKU. Main Outcomes and Measures: The blood PHE concentration was regularly measured from 2018 to 2021. A 1-sided Z test was used to compare the mean of the blood PHE concentration between different years. Results: Among 167 patients with PKU (mean [SD] age, 84.4 [48.3] months; 87 males [52.1%]), a total of 4285 measurements of their blood PHE concentration were collected from 2018 to 2021. For patients at the center that canceled the reimbursement policy in 2019, the mean (SD) of the blood PHE concentrations in 2019 was 5.95 (5.73) mg/dL, significantly higher than 4.84 (4.11) mg/dL in 2018 (P < .001), 5.06 (5.21) mg/dL in 2020 (P = .006), and 4.77 (4.04) mg/dL in 2021 (P < .001). Similarly, for patients at the other center that canceled the policy in 2019, the mean (SD) of the blood PHE concentrations in 2019 was 5.95 (3.43) mg/dL, significantly higher than 5.34 (3.45) mg/dL in 2018 (P = .03), 5.13 (3.15) mg/dL in 2020 (P = .003), and 5.39 (3.46) mg/dL in 2021 (P = .03). On the contrary, no significant difference was observed between any of the years for patients at the 2 centers that consistently implemented the policy. Conclusions and Relevance: In this cohort study of patients with PKU from multiple centers, the implementation of the reimbursement policy for special foods was associated with controlling the blood PHE concentration. Special foods expenditure for patients with PKU should be included in the scope of long-term social medical insurance reimbursement.

Unveiling the Hidden Discrepancies Between Medicare Physician Reimbursement Rates and Inflation Across Different Surgical Specialties.

OBJECTIVE: This study aimed to analyze the trends of Medicare physician reimbursement from 2011 to 2021 and compare the rates across different surgical specialties. BACKGROUND: Knowledge of Medicare is essential because of its significant contribution in physician reimbursements. Previous studies across surgical specialties have demonstrated that Medicare, despite keeping up with inflation in some areas, has remained flat when accounting for physician reimbursement. STUDY DESIGN: The Physician/Supplier Procedure Summary data for the calendar year 2021 were queried to extract the top 50% of Current Procedural Terminology codes based on case volume. The Physician Fee Schedule look-up tool was accessed, and the physician reimbursement fee was abstracted. Weighted mean reimbursement was adjusted for inflation. Growth rate and compound annual growth rate were calculated. Projection of future inflation and reimbursement rates were also calculated using the US Bureau of Labor Statistics. RESULTS: After adjusting for inflation, the weighted mean reimbursement across surgical specialties decreased by -22.5%. The largest reimbursement decrease was within the field of general surgery (-33.3%), followed by otolaryngology (-31.5%), vascular surgery (-23.3%), and plastic surgery (-22.8%). There was a significant decrease in median case volume across all specialties between 2011 and 2021 (P < 0.001). CONCLUSIONS: This study demonstrated that, when adjusted for inflation, over the study period, there has been a consistent decrease in reimbursement for all specialties analyzed. Awareness of the current downward trends in Medicare physician reimbursement should be a priority for all surgeons, as means of advocating for compensation and to maintain surgical care feasible and accessible to all patients.

Quantified trends in provider reimbursement and utilization volume in colorectal cancer screenings: analysis of Medicare claims from 2000 to 2019.

AIM: Colorectal cancer (CRC) screening rates in the United States remain persistently below guideline targets, partly due to suboptimal patient utilization and provider reimbursement. To guide long-term national utilization estimates and set reasonable screening adherence targets, this study aimed to quantify trends in utilization of and reimbursement for CRC screenings using Medicare claims. METHOD: Inflation-adjusted reimbursements and utilization volume associated with each CRC screening code were abstracted from Medicare claims between 2000 and 2019. Screenings, screenings/100 000 enrolees and reimbursement/screening were analysed with linear regression and compared with the equality of slopes tests. Average reimbursement per screening was compared using analysis of variance with Dunnett's T3 multiple comparisons test. RESULTS: The growth rate of multitarget stool DNA tests (mt-sDNA)/100 000 was the highest at 170.4 screenings/year (R2 = 0.99, p ≤ 0.001), while that of faecal occult blood tests/100 000 was the lowest at -446.4 screenings/year (R2 = 0.90, p ≤ 0.001) (p ≤ 0.001). Provider reimbursements averaged $546.95 (95% CI $520.12-$573.78) per mt-sDNA screening, significantly higher than reimbursements for all invasive screenings. Only FOBTs significantly increased in reimbursement per screening at $0.62/year (R2 = 0.91, p ≤ 0.001). CONCLUSION: We derived forecastable trend numbers for utilization and provider reimbursement. Faecal immunochemical tests/100 000 and mt-sDNA screenings/100 000 increased most rapidly during the entire study period. The number of nearly all invasive screenings/100 000 decreased rapidly; the number of colonoscopies/100 000 increased slightly, probably due to superior diagnostic strength. These trends indicate the that replacement of other invasive modalities with accessible noninvasive screenings will account for much of future screening behaviour and thus reductions in CRC incidence and mortality, especially given providers' reimbursement incentive to screen average-risk patients with stool-based tests.

Association of Medicaid Reimbursement Policies with Provision of Long-Acting Reversible Contraception in the Postpartum Period, 2012-2018.

Background: To address reimbursement challenges associated with long-acting reversible contraception (LARC) in the postpartum period, state Medicaid programs have provided additional payments ("carve-outs"). Implementation has been heterogeneous, with states providing separate payments for the device only, procedure only, or both the device and procedure. Methods: Claims data were drawn from 210,994 deliveries in the United States between 2012 and 2018. Using generalized estimating equations, we assess the relationship between Medicaid carve-out policies and the likelihood of LARC placement at (1) 3 days postpartum, (2) 60 days postpartum, and (3) 1 year postpartum, in Medicaid and commercially insured populations. Results: Among Medicaid beneficiaries, the likelihood of receiving LARC was higher in states with any carve-out, compared with states without carve-outs, at 3 days (adjusted odds ratio [aOR] 1.49 [95% confidence interval: 1.33-1.67], p < 0.001), 60 days (aOR: 1.40 [95% CI: 1.35-1.46], p < 0.001), and 1 year postpartum (aOR: 1.15 [95% CI: 1.11-1.20], p < 0.001). Adjustments were made for geographic region, seasonality, and patient age. Heterogeneity was observed by carve-out type; device carve-outs were consistently associated with greater likelihood of postpartum LARC placement, compared with states with no carve-outs. Similar trends were observed among commercially insured patients. Conclusion: Findings support the effectiveness of Medicaid carve-outs on postpartum LARC provision, particularly for device carve-outs, which were associated with increased postpartum LARC placement at 3 days, 60 days, and 1 year postpartum. This outcome suggests that policies to address cost-related barriers associated with LARC devices may prove most useful in overcoming barriers to immediate postpartum LARC placement, with the overarching aim of promoting reproductive autonomy.

Examining the Impact of the Current Reimbursement Regulation on Patient Access to Innovative Medical Devices in Taiwan: Insights From 8 Years' Reimbursement Data.

OBJECTIVES: This study aimed to assess the impact of the reimbursement regulation of medical devices (Regulation), introduced by the National Health Insurance Administration (NHIA) in 2013, on patients' access to innovative medical devices in Taiwan. METHODS: Analysis of the amount of time needed from application for NHIA reimbursement for new medical devices to receiving the decision from NHIA was done using the nonreimbursement product list featured on the NHIA website. Additionally, Welch analysis of variance was used to compare the amount of time it took from application to NHIA with reimbursement decisions made by the NHIA for different nonreimbursement code categories. Further, related Pharmaceutical Benefit Reimbursement Scheme meeting minutes were analyzed to obtain more detailed information concerning medical devices' reimbursement or not. RESULTS: From December 2012 to June 2021, the overall reimbursement percentage was 56.7%, and the average amount of time between application and reimbursement was 856.7 ± 474.7 days. The mandatory reimbursement rate was about 45%. NHIA reimbursement decisions as special medical devices also take a longer amount of time, because the applicants need to agree to the decision (P < .05). The NHIA decision-making process for nonreimbursement medical devices requires a significantly longer amount of time than for general materials (eg, suture, etc) decisions. CONCLUSIONS: Although the Regulation resolves payment issues, it also increases the amount of time to reach reimbursement decisions, thus hindering patient access to innovative medical devices. The study suggests that the review process needs to be simplified concerning reimbursement notification, using local real-world data to support reimbursement decisions.

The impact of losartan on the lifetime incidence of ESRD and costs in Mexico / El impacto del losartan en la incidencia de por vida de la enfermedad renal de la etapa terminal y sus costos en México

Background. The RENAAL (Reduction of Endpoints in Type 2 Diabetes with the Angiotensin II Antagonist Losartan) study demonstrated that treatment with losartan reduced the risk of ESRD by 29% among hypertensive patients with type 2 diabetes and diabetic nephropathy. The objective of this study was to project the effect of losartan compared to placebo on the lifetime incidence of ESRD and associated costs from a third-party payer perspective in Mexico. Methods. A competing risks method was used to estimate lifetime incidence of ESRD, while accounting for the risk of death without ESRD. The cost associated with ESRD was estimated by combining the cumulative incidence of ESRD with the lifetime cost associated with ESRD. Total cost was estimated as the sum of the cost associated with ESRD from the three main public institutions in Mexico, the lifetime cost of losartan therapy, and other costs (non-ESRD/non-losartan) expected for patients with type 2 diabetes. Survival was estimated by weighting the life expectancies with and without ESRD by the cumulative risk of ESRD. Results. The projected lifetime incidence of ESRD for losartan patients was lower (66%) compared with placebo patients (83%). This reduction in ESRD resulted in a decrease in ESRD-related cost of M$49,737 per patient and a discounted gain of 0.697 life years per patient. After accounting for the cost of losartan and the additional cost associated with greater survival, we projected that treatment with losartan would result in a net savings of M$24,073 per patient. Conclusion. Treatment with losartan in patients with type 2 diabetes and nephropathy not only reduced the within-trial incidence of ESRD but is projected to result in lifetime reductions in ESRD, increased survival, and overall cost savings to public institutions in Mexico.

Antecedentes. El estudio RENAAL (Reducción de los grados o puntos terminales en la diabetes tipo 2 con losartan, el antagonista de la anglotenslna II) demostró que el tratamiento con losartan redujo el riesgo de la ESRD (enfermedad renal de la etapa terminal) en 29% entre pacientes hipertensos con diabetes tipo 2 y neuropatía diabética. El propósito estudiado fue hacer una proyección del efecto del losartan comparándolo con el placebo en la incidencia de por vida de la ESRD y con los costos asociados de un tercer pagador en perspectiva en México. Métodos. Se utilizó un método de riesgos muy competitivo para calcular la incidencia de por vida de la ESRD, al mismo tiempo que se calculaba el riesgo de muerte sin la ESRD. El costo asociado con la ESRD se calculó confirmando la incidencia acumulativa de la ESRD en relación con el costo de por vida de la terapia con losar-tan y otros costos (sin ESRD o sin losartan) con los que se contaba para pacientes con diabetes tipo 2. La supervivencia se calculó esperando las expectativas de vida con y sin ESRD por el riesgo acumulativo de ESRD. Resultados. La proyectada incidencia de por vida de la ESRD en cuanto a los pacientes con losartan fue más baja (66%) comparada con los pacientes que tomaron placebo (83%). Esta reducción de la ESRD tuvo por resultado una disminución en el costo relacionado con la ESRD de $49,737 por paciente y una ganancia descartada de 0.697 años de vida por paciente. Luego de contabilizar el costo del losartan y el costo añadido asociado con una mayor supervivencia, llegamos a la conclusión de que el tratamiento con losartan daría por resultado un ahorro neto de $24,073 por paciente. Conclusión. El tratamiento mediante losartan en pacientes aquejados de diabetes tipo 2 y neuropatía no sólo redujo la incidencia intraexperimental de la ESRD, sino que además nos ha servido para proyectar que resulte en reducciones de por vida en la ESRD, en una supervivencia incrementada y en un ahorro total de costos en cuanto a las instituciones públicas en nuestro país.
