Real-world effectiveness of benralizumab: Results from the ZEPHYR 1 Study.

BACKGROUND: Real-world evidence characterizing the clinical outcomes and economic impact on patients with severe eosinophilic asthma treated with benralizumab is limited. OBJECTIVE: To characterize patients with severe asthma treated with benralizumab and assess its clinical and economic impact in the United States. METHODS: A pre-post benralizumab comparison was performed using a large US insurance claims database between November 2016 and November 2019. The primary cohort included patients with asthma aged 12 years or more with 2 or more records of benralizumab. Secondary cohorts included persistent users (6 or more records of benralizumab), patients switching to benralizumab from mepolizumab or omalizumab, and stratified by Medicaid vs non-Medicaid. Exacerbations, concomitant medications, and exacerbation-related health care resource utilization (HCRU) and costs were compared in the 12-month periods pre- and post-benralizumab initiation (index). RESULTS: Of the 204 patients in the primary cohort, mean age at index was 45.3 years and 68.6% were of female sex. The patients experienced a significant 55% reduction in rates of exacerbations post-benralizumab initiation (3.25 pre-index vs 1.47 post-index per person-year; P < .001), and 41% of the patients had no exacerbations post-benralizumab initiation. The proportion of oral corticosteroid-dependent patients decreased from 82% to 50% (P < .001). Reductions in HCRU were 42%, 46%, and 57% for asthma exacerbation-related inpatient hospitalizations, emergency department, and outpatient visits, respectively (all P < .001). Exacerbation-related costs decreased by $6439 ($13,559 vs $7120; P < .001). Similar results for all outcomes were observed for the persistent cohort, switch cohorts, and Medicaid vs non-Medicaid cohorts. CONCLUSION: Patients with severe asthma treated with benralizumab experienced clinical and economic benefits in the real world, as demonstrated by the reduction in exacerbations and HCRU.

Prospective evaluation of the impact of stress, anxiety, and depression on household income among young women with early breast cancer from the Young and Strong trial.

BACKGROUND: Young women with breast cancer tend to report lower quality of life and higher levels of stress than older women with breast cancer, and this may have implications for other psychosocial factors including finances. We sought to determine if stress, anxiety, and depression at diagnosis were associated with changes in household income over 12-months in young women with breast cancer in the United States. METHODS: This study was a prospective, longitudinal cohort study comprised of women enrolled in the Young and Strong trial. Of the 467 women aged 18-45 newly diagnosed with early-stage breast cancer enrolled in the Young and Strong trial from 2012 to 2013, 356 (76%) answered income questions. Change in household income from baseline to 12 months was assessed and women were categorized as having lost, gained, maintained the same household income <$100,000, or maintained household income ≥$100,000. Patient-reported stress, anxiety, and depression were assessed close to diagnosis at trial enrollment. Adjusted multinomial logistic regression models were used to compare women who lost, gained, or maintained household income ≥$100,000 to women who maintained the same household income <$100,000. RESULTS: Although most women maintained household income ≥$100,000 (37.1%) or the same household income <$100,000 (32.3%), 15.4% lost household income and 15.2% gained household income. Stress, anxiety, and depression were not associated with gaining or losing household income compared to women maintaining household incomes <$100,000. Women with household incomes <$50,000 had a higher risk of losing household income compared to women with household incomes ≥$50,000. Women who maintained household incomes ≥$100,000 were less likely to report financial or insurance problems. Among women who lost household income, 56% reported financial problems and 20% reported insurance problems at 12 months. CONCLUSIONS: Baseline stress, anxiety, and depression were not associated with household income changes for young women with breast cancer. However, lower baseline household income was associated with losing household income. Some young survivors encounter financial and insurance problems in the first year after diagnosis, and further support for these women should be considered.

L'infirmière pivot associée à une expérience de soins oncologiques positive et à une satisfaction accrue des patients.

CONTEXTE ET OBJECTIFS: Un nombre croissant de résultats probants indique que l'infirmière pivot en oncologie (IPO) joue un rôle de premier plan dans l'optimisation des processus et des résultats de soins. Il faudra toutefois mener des études d'envergure pour comparer les perceptions de l'expérience de soins liés au cancer des patients traités par des infirmières pivots et de ceux qui n'ont pas bénéficié de ce type de suivi. MÉTHODOLOGIE: Des participants (N = 2 858) traités au cours des six derniers mois dans un centre de traitement du cancer situé à Montréal, au Québec, et affilié à une université ont répondu au sondage sur la satisfaction des patients en traitement anticancéreux ambulatoire, c'est-à-dire le Ambulatory Oncology Patient Satisfaction Survey (AOPSS). RÉSULTATS: L'expérience des soins oncologiques était significativement plus positives et la satisfaction plus élevée dans le groupe suivi par une infirmière pivot (n = 2 003) pour les six domaines de soins (différences moyennes de 3,32 à 8,95) et les quatre fonctions infirmières (différences moyennes de 5,64 à 10,39), comparativement au groupe sans IPO (n = 855). DISCUSSION: L'infirmière pivot joue un rôle important dans l'amélioration de l'expérience de soins et la satisfaction des patients. Les recherches futures devront explorer les potentielles relations de cause à effet entre les infirmières pivots, les processus de soins et les résultats des patients.

The nurse pivot-navigator associated with more positive cancer care experiences and higher patient satisfaction.

BACKGROUND AND OBJECTIVES: Growing evidence indicates that the nurse navigator-pivot (NN), is key to optimizing care processes and outcomes. However, large scale studies are needed to examine how patients exposed to NNs (as opposed to non-NN) differentially perceived their cancer care experiences. METHOD: Participants (N = 2,858) treated for cancer in the last six months at university-affiliated cancer centres in Montréal, Québec, completed the Ambulatory Oncology Patient Satisfaction Survey (AOPSS). RESULTS: Cancer care experiences and satisfaction were significantly higher in the NN group (n = 2,003) for all six care domains (Ds from 3.32 to 8.95) and all four nursing functions (Ds from 5.64 to 10.39) when compared to the non-NN group (n = 855). DISCUSSION: The NN role is significantly related to enhanced cancer care experiences and higher patient satisfaction. Future research should explore potential causal effects between NNs and care processes, as well as patient outcomes.

College affirmative action bans and smoking and alcohol use among underrepresented minority adolescents in the United States: A difference-in-differences study.

BACKGROUND: College affirmative action programs seek to expand socioeconomic opportunities for underrepresented minorities. Between 1996 and 2013, 9 US states-including California, Texas, and Michigan-banned race-based affirmative action in college admissions. Because economic opportunity is known to motivate health behavior, banning affirmative action policies may have important adverse spillover effects on health risk behaviors. We used a quasi-experimental research design to evaluate the association between college affirmative action bans and health risk behaviors among underrepresented minority (Black, Hispanic, and Native American) adolescents. METHODS AND FINDINGS: We conducted a difference-in-differences analysis using data from the 1991-2015 US national Youth Risk Behavior Survey (YRBS). We compared changes in self-reported cigarette smoking and alcohol use in the 30 days prior to survey among underrepresented minority 11th and 12th graders in states implementing college affirmative action bans (Arizona, California, Florida, Michigan, Nebraska, New Hampshire, Oklahoma, Texas, and Washington) versus outcomes among those residing in states not implementing bans (n = 35 control states). We also assessed whether underrepresented minority adults surveyed in the 1992-2015 Tobacco Use Supplement to the Current Population Survey (TUS-CPS) who were exposed to affirmative action bans during their late high school years continued to smoke cigarettes between the ages of 19 and 30 years. Models adjusted for individual demographic characteristics, state and year fixed effects, and state-specific secular trends. In the YRBS (n = 34,988 to 36,268, depending on the outcome), cigarette smoking in the past 30 days among underrepresented minority 11th-12th graders increased by 3.8 percentage points after exposure to an affirmative action ban (95% CI: 2.0, 5.7; p < 0.001). In addition, there were also apparent increases in past-30-day alcohol use, by 5.9 percentage points (95% CI: 0.3, 12.2; p = 0.041), and past-30-day binge drinking, by 3.5 percentage points (95% CI: -0.1, 7.2, p = 0.058), among underrepresented minority 11th-12th graders, though in both cases adjustment for multiple comparisons resulted in failure to reject the null hypothesis (adjusted p = 0.083 for both outcomes). Underrepresented minority adults in the TUS-CPS (n = 71,575) exposed to bans during their late high school years were also 1.8 percentage points more likely to report current smoking (95% CI: 0.1, 3.6; p = 0.037). Event study analyses revealed a discrete break for all health behaviors timed with policy discussion and implementation. No substantive or statistically significant effects were found for non-Hispanic White adolescents, and the findings were robust to a number of additional specification checks. The limitations of the study include the continued potential for residual confounding from unmeasured time-varying factors and the potential for recall bias due to the self-reported nature of the health risk behavior outcomes. CONCLUSIONS: In this study, we found evidence that some health risk behaviors increased among underrepresented minority adolescents after exposure to state-level college affirmative action bans. These findings suggest that social policies that shift socioeconomic opportunities could have meaningful population health consequences.

Trends of two HPV-associated cancers in Massachusetts: cervical and oropharyngeal cancer.

PURPOSE: To understand trends in the incidence and mortality of two human papillomavirus (HPV)-associated cancers, cervical and oropharyngeal cancer, in Massachusetts. METHODS: From 2004 to 2014, the Massachusetts Cancer Registry recorded 3,996 incident cases of oropharyngeal cancer and 2,193 incident cases of cervical cancer. Mortality data were obtained from the Massachusetts Registry of Vital Records and Statistics from 2008 to 2014. Rates were age-standardized to the 2000 U.S. population and trends were assessed using joinpoint regression. RESULTS: While the incidence rate of cervical cancer (5.46 per 100,000) decreased by 2.41% annually (p = 0.004), the incidence rate of oropharyngeal cancer among males (7.85 per 100,000) increased by 2.82% annually (p = 0.0002). Mortality rates for both cancers decreased from 2008 to 2014 but were not statistically significant (cervical - 3.73% annually, p = 0.29; oropharyngeal - 1.94% annually, p = 0.44). CONCLUSION: The rising incidence rate of oropharyngeal cancer in men and the decreasing, but relatively high, incidence rate of cervical cancer in women highlight the need for further screening and prevention by HPV vaccination in Massachusetts.

Cervical Cancer Incidence Among Elderly Women in Massachusetts Compared With Younger Women.

IMPORTANCE: Current cancer screening guidelines recommend cessation of cervical cancer screening at the age of 65 years for most women. To examine residual risk among elderly women, we compared cervical cancer incidence rates (IRs) in Massachusetts from 2004 to 2015 among women younger than 65 years versus 65 years and older. MATERIALS AND METHODS: The Massachusetts Cancer Registry was used to identify all women diagnosed with cervical cancer between January 01, 2004, to December 31, 2015. Cancer incidence was calculated based on age of diagnosis (<65 years vs ≥65 years). RESULTS: In Massachusetts, 2,418 incident cases of cervical cancer were diagnosed from 2004 to 2014, of which 571 (23.6%) were diagnosed among women 65 years and older. When compared with women diagnosed younger than 65 years, women diagnosed at the age of 65 years and older were more likely to be diagnosed with stage II or higher (71.8% vs 43.8%, p < .001). Cervical cancer IRs decreased annually for women younger than 65 years from 2004 to 2015. Among women 65 years and older, cancer IRs decreased by 3.9% annually from 2004 to 2013 (p = .0009), but 2013 to 2015 showed an increasing trend (annual percent change + 14.1%, p = .12). CONCLUSIONS AND RELEVANCE: Women 65 years and older account for one quarter of cervical cancer diagnoses in Massachusetts and present with higher-stage disease than younger women. Upcoming planned revisions in screening and prevention guidelines should address the continued risk of cervical cancer for older women.

Patient-reported care domains that enhance the experience of "being known" in an ambulatory cancer care centre.

PURPOSE: This study explored patients' perceptions of "being known" in an ambulatory chemotherapy unit. METHODS: Using a qualitative descriptive design, 10 participants with various cancer diagnoses were recruited from a large cancer centre in Montreal, Quebec. Audiotaped individual interviews were transcribed verbatim. Textual data were coded and analyzed thematically. FINDINGS: Participants spoke of their need to have the staff approach them as individuals first and then as persons with cancer. They further underscored the importance of: (1) feeling truly welcome in the cancer care environment, (2) being provided with person- and situation-responsive care, and (3) considering occupational and social roles that go beyond the "sick role". Mutual patient-nurse disclosure also contributed to perceptions of a personalized care approach. IMPLICATIONS FOR NURSING: In addition to key elements construed as crucial for enhancing perceptions of being known, future studies should further document how the interplay among demographic, physical/psychological, and cultural factors affect these perceptions.

Service providers' perceptions of and responses to bullying of individuals with disabilities.

A sample of 124 service providers (e.g. mental health professionals, educators, administrators) completed a survey about bullying of individuals with disabilities and the use and perceived effectiveness of resources and strategies to address bullying. Providing support and performing an action in response to bullying were reported to be used more often and were perceived as more effective than education and minimizing/ignoring. Service providers who reported that the individuals they worked with experienced cyberbullying more frequently were more likely to take action and use education. Those who attributed victimization to social differences were more likely to provide support.

The genome of the fire ant Solenopsis invicta.

Ants have evolved very complex societies and are key ecosystem members. Some ants, such as the fire ant Solenopsis invicta, are also major pests. Here, we present a draft genome of S. invicta, assembled from Roche 454 and Illumina sequencing reads obtained from a focal haploid male and his brothers. We used comparative genomic methods to obtain insight into the unique features of the S. invicta genome. For example, we found that this genome harbors four adjacent copies of vitellogenin. A phylogenetic analysis revealed that an ancestral vitellogenin gene first underwent a duplication that was followed by possibly independent duplications of each of the daughter vitellogenins. The vitellogenin genes have undergone subfunctionalization with queen- and worker-specific expression, possibly reflecting differential selection acting on the queen and worker castes. Additionally, we identified more than 400 putative olfactory receptors of which at least 297 are intact. This represents the largest repertoire reported so far in insects. S. invicta also harbors an expansion of a specific family of lipid-processing genes, two putative orthologs to the transformer/feminizer sex differentiation gene, a functional DNA methylation system, and a single putative telomerase ortholog. EST data indicate that this S. invicta telomerase ortholog has at least four spliceforms that differ in their use of two sets of mutually exclusive exons. Some of these and other unique aspects of the fire ant genome are likely linked to the complex social behavior of this species.

Stratified Patient Profiling for Vedolizumab Effectiveness in Crohn's Disease: Identifying Optimal Subgroups for Enhanced Treatment Response in the EVOLVE Study.

INTRODUCTION: This analysis evaluated the relative performance of vedolizumab and anti-tumor necrosis factor alpha (anti-TNFα) agents in subpopulations of biologic therapy-naive patients with Crohn's disease (CD) and assessed whether patients in whom vedolizumab would have a larger treatment effect vs anti-TNFα agents could be identified. METHODS: Data were from EVOLVE, a real-world, multicountry, retrospective cohort study of patients with inflammatory bowel disease who initiated first-line biologic treatment with vedolizumab (n = 195) or anti-TNFα agents (n = 245). Prediction models for time to clinical remission were developed in vedolizumab- and anti-TNFα-treated patients and used to estimate effect scores, a metric of predicted comparative efficacy, for each patient. Patients were ranked by effect scores and potential subpopulations were investigated. Simplified rules to identify these subpopulations were also developed using classification tree analysis. RESULTS: Among all patients, median time to clinical remission was 7.8 months (vedolizumab) and 11.1 months (anti-TNFα) (P < 0.05). Among patients in the top 40% of the effect score distribution, the median time to clinical remission was 4.8 months (vedolizumab) vs 18.1 months (anti-TNFα) (adjusted hazard ratio 2.0, 95% confidence interval 1.3-2.9). A simplified rule for identifying a subpopulation more likely to benefit from vedolizumab was based on having an ongoing CD exacerbation, no prior emergency visits, and non-stricturing disease. CONCLUSIONS: Subpopulations of biologic-naive patients with CD in whom vedolizumab appeared to have a larger effect relative to anti-TNFα agents for the outcome of clinical remission were identified. Validation of the identified subpopulations and simplified rules are warranted to confirm these findings. GOV IDENTIFIER: NCT03710486. Graphical Abstract available for this article.

Economic burden of recurrent hyperkalemia in patients with chronic kidney disease.

BACKGROUND: Hyperkalemia is a common complication of chronic kidney disease (CKD) and can become recurrent in half of cases. However, the incremental economic burden associated with recurrent hyperkalemia is unknown. OBJECTIVE: To evaluate all-cause health care resource utilization (HRU) and medical costs in patients with stage 3/4 CKD with recurrent hyperkalemia vs normokalaemia and vs nonrecurrent hyperkalemia. METHODS: Data were from Optum's de-identified Market Clarity Data (January 1, 2016, to August 1, 2022). This retrospective observational cohort study compared patients with stage 3/4 CKD with recurrent hyperkalemia (≥2 hyperkalemia events within 1 year [hyperkalemia event: hyperkalemia diagnosis or potassium [K+]>5 mmol/l]; index was the first hyperkalemia event) with an exact- and propensity score-matched cohort of patients with normokalemia (K+ ≥3.5 to ≤5 mmol/l; random K+ as index) and separately with a matched cohort of patients with nonrecurrent hyperkalemia (1 hyperkalemia event within 1 year; index was hyperkalemia event). Patient characteristics, medication use, HRU, and medical costs were compared between cohorts using standardized mean differences during the 12-month baseline period. All-cause HRU and medical costs during the 12-month follow-up were compared using Wilcoxon rank sum tests for continuous variables and McNemar tests for categorical variables. Substudies of recurrent hyperkalemia vs normokalemia were conducted for patients with Medicare coverage and renin-angiotensin-aldosterone system inhibitor (RAASi) use. RESULTS: The recurrent hyperkalemia vs normokalemia sample comprised 4,549 matched pairs (Medicare substudy: 3,151; RAASi substudy: 3,535) and the recurrent hyperkalemia vs nonrecurrent hyperkalemia sample comprised 1,599 matched pairs. Baseline characteristics, HRU, and medical costs of the cohorts were similar after matching. During follow-up, patients with recurrent hyperkalemia had a mean of 11.2 more health care encounters (0.5 more inpatient admissions, 0.3 more emergency department visits, and 7.2 more outpatient visits) than patients with normokalemia. Patients with recurrent hyperkalemia also had double the total annual medical costs vs normokalemia ($34,163 vs $15,175; P < 0.001), mainly driven by inpatient costs ($21,250 vs $7,392), which accounted for 62.2% and 48.7% of total costs, respectively. Results were similar in the RAASi and Medicare substudies. Recurrent hyperkalemia was associated with a mean 4.3 more all-cause health care encounters and $14,057 higher medical costs (both P < 0.001) than nonrecurrent hyperkalemia. CONCLUSIONS: Recurrent hyperkalemia in patients with stage 3/4 CKD was associated with higher all-cause HRU and medical costs compared with normokalemia (including in patients with Medicare coverage and RAASi use) and nonrecurrent hyperkalemia. Research is needed to understand if long-term treatment strategies aimed at preventing hyperkalemia recurrence may alleviate this economic burden.

Hyperkalemia and risk of chronic kidney disease progression: A propensity score matched analysis.

BACKGROUND: Hyperkalemia is a known complication of chronic kidney disease (CKD); however, it is not known whether hyperkalemia directly contributes to CKD progression and the risk of death. Clarifying the extent to which hyperkalemia is associated with CKD progression and mortality can inform clinical practice and guide future research. The objective of this study was to quantify the risks of CKD progression and mortality associated with hyperkalemia in patients with stages 3b/4 CKD. METHODS: This was a real-world, exact and propensity score-matched, observational cohort study using data (January 2016-December 2021) from Optum's deidentified Market Clarity Data, a large US integrated insurance claims/electronic medical record database. The study included matched adult patients with stages 3b/4 CKD with and without hyperkalemia, not regularly treated with an intestinal potassium (K+) binder. Measured outcomes were CKD progression and all-cause mortality. CKD progression was defined as diagnosis of CKD stage 4 (if stage 3b at index), CKD stage 5 or kidney failure, or receipt of dialysis or kidney transplantation. RESULTS: After matching, there were 6,619 patients in each of the hyperkalemia and non-hyperkalemia cohorts, with a mean (standard deviation) follow-up time of 2.12 (1.42) years. Use of any renin-angiotensin-aldosterone system inhibitors (RAASi) during baseline was common (75.9%) and most patients had CKD stage 3b (71.2%). Patients with hyperkalemia had a 1.60-fold (95% confidence interval [CI] 1.50, 1.71) higher risk of CKD progression and a 1.09-fold (1.02, 1.16) higher risk of all-cause mortality relative to patients without hyperkalemia. Relative risks of CKD progression associated with hyperkalemia were similar within the subset of patients receiving RAASi and across CKD stages, and when alternative definitions of CKD progression were used. CONCLUSIONS: Patients with CKD stages 3b/4 and hyperkalemia experienced significantly higher risks of CKD progression and all-cause mortality than propensity score-matched patients without hyperkalemia.

Association of Serum Calcium and Phosphate With Incident Cardiovascular Disease in Patients With Hypoparathyroidism.

The pathophysiological basis for the increased incidence of cardiovascular disease in patients with chronic hypoparathyroidism is poorly understood. To evaluate associations between levels of albumin-corrected serum calcium, serum phosphate, and calcium-phosphate product with the odds of developing cardiovascular events in patients with chronic hypoparathyroidism with ≥1 calcitriol prescription, we conducted a retrospective nested case-control study of patients who developed a cardiovascular event and matched controls without an event. The primary outcome was the instance of cardiovascular events. An electronic medical record database was used to identify 528 patients for the albumin-corrected serum calcium analysis and 200 patients for the serum phosphate and calcium-phosphate product analyses. Patients with ≥67% of albumin-corrected serum calcium measurements outside the study-defined 2.00 to 2.25 mmol/L (8.0 to 9.0 mg/100 ml) range had 1.9-fold higher odds of a cardiovascular event (adjusted odds ratio, 95% confidence interval 1.89, 1.10 to 3.25) compared with patients with <33% of calcium measurements outside the range. Likewise, patients with any serum phosphate measurements above 0.81 to 1.45 mmol/L (2.5 to 4.5 mg/100 ml) had 3.3-fold higher odds (3.26; 1.24 to 8.58), and those with any calcium-phosphate product measurements above 4.40 mmol2/L2 (55 mg2/dL2) had 4.8-fold higher odds of a cardiovascular event (95% confidence interval 1.36 to 16.81) compared with patients with no measurements above these ranges. In adult patients with chronic hypoparathyroidism, a cardiovascular event was more likely in those with a higher proportion of albumin-corrected serum calcium measurements outside 2.00 to 2.25 mmol/L (8.0 to 9.0 mg/100 ml) or any serum phosphate and any calcium-phosphate product measurements above the normal population range.

Assessment of women's treatment preferences for vasomotor symptoms due to menopause.

BACKGROUND: Several therapies for vasomotor symptoms (VMS) due to menopause are available. Treatment preferences and willingness-to-pay for VMS treatment among US women with VMS were evaluated. METHODS: An online survey of women with perimenopausal or postmenopausal VMS was conducted (3/15/21-4/23/21). A discrete choice experiment quantified the impact of 7 treatment attributes on VMS treatment choice: VMS frequency/severity reduction, sleep improvement, risk of breast cancer/cardiovascular events in 6 years, risk of short-term side effects, and out-of-pocket costs. Preference weights (PWs) with 95% confidence intervals (CIs) were estimated and reported. RESULTS: Among 467 women, 86.5% and 87.8% reported moderate to very severe VMS and sleep problems during the preceding month, respectively. Sleep improvement (PW: 0.843; 95% CI: 0.721, 0.965) and reduction in VMS frequency (PW: 0.658; 95% CI: 0.520, 0.796) and severity (PW: 0.628; 95% CI: 0.500, 0.756) most influenced treatment preference; risk of cardiovascular events (PW: 0.150; 95% CI: 0.069, 0.232) or breast cancer (PW: 0.401; 95% CI: 0.306, 0.496) in 6 years had lesser effect. Willingness-to-pay was an additional $35-$46/month for substantially improved sleep, 80% VMS frequency reduction, and reduction from severe to mild VMS. CONCLUSIONS: Sleep improvement and reductions in VMS frequency/severity were the most important treatment attributes.

Hormone and non-hormone treatments are available to reduce vasomotor symptoms (hot flashes and night sweats) due to menopause. We conducted an online survey of 467 women with moderate to very severe vasomotor symptoms during perimenopause or postmenopause to learn what treatment attributes are most important to women when selecting from among the available therapies and how much women were willing to pay for the attributes. Women were shown 14 cards, each with a side-by-side comparison of 2 treatments with varying descriptions of the following 7 treatment attributes: reduction in frequency of vasomotor symptoms, reduction in severity of vasomotor symptoms, improvement in sleep, risk of breast cancer in 6 years, risk of cardiovascular events in 6 years, risk of short-term side effects, and out-of-pocket costs. Women picked their preferred treatment on each card. Results showed that improvement in sleep was the most important attribute to women, and they were willing to pay an extra $46/month for a treatment that substantially improved sleep. The next most important attributes were reduction in frequency and reduction in severity of vasomotor symptoms. Women were willing to pay $36/month more for a treatment that reduced symptom frequency by 80% compared with one that reduced frequency by 50%, and they were willing to pay $35/month more for treatment that reduced symptoms from severe to mild compared with one that did not reduce symptom severity. These results may help guide development of new treatment options and may help physicians recommend treatments that best fit women's preferences.

Cost-Effectiveness Analysis of REBYOTA™ (Fecal Microbiota, Live-jslm [FMBL]) Versus Standard of Care for the Prevention of Recurrent Clostridioides difficile Infection in the USA.

INTRODUCTION: Recurrent Clostridioides difficile infection (rCDI) is common and associated with considerable clinical and economic consequences. REBYOTA™ (fecal microbiota, live-jslm [FMBL]) is a microbiota-based live biotherapeutic approved for the prevention of rCDI following antibiotic treatment for rCDI. We sought to evaluate cost-effectiveness of FMBL compared to standard of care (SOC) from a US third-party payer perspective among patients with one or more (≥ 1) recurrences. METHODS: A Markov model with a lifetime time horizon was developed. The model population included adult patients who had ≥ 1 recurrence after a primary CDI episode and had completed ≥ 1 round of antibiotics, or had ≥ 2 severe CDI episodes resulting in hospitalization within the last year. The model consisted of six health states with an 8-week model cycle: rCDI, absence of CDI after recurrence, colectomy, ileostomy, ileostomy reversal, and death. Drug costs and rCDI-related medical costs were estimated in 2022 US dollars and discounted at 3% annually. Deterministic sensitivity analyses were performed. RESULTS: Compared to SOC, FMBL at $9000/course resulted in an incremental cost-effectiveness ratio (ICER) of $18,727 per quality-adjusted life year (QALY) gained. The incremental cost was $5336 (FMBL $79,236, SOC $73,900) and the incremental effectiveness was 0.285 QALYs (FMBL 10.346, SOC 10.061). The cumulative drug acquisition and administration costs for the FMBL and SOC arms were $24,245 and $16,876, while rCDI-related medical costs for FMBL and SOC were $54,991 and $57,024, respectively. The ICER in the subgroup of patients at first recurrence was $13,727 per QALY gained. FMBL remained cost-effective across all sensitivity analyses. CONCLUSIONS: FMBL was found to be cost-effective compared to SOC for the prevention of rCDI with more benefits among patients at first recurrence, with an ICER far below the payer ICER threshold of $100,000. Patients treated with FMBL experienced higher total QALYs and reduced healthcare resource utilization, including reduced hospitalizations.

Budget Impact Analysis of REBYOTA™ (Fecal Microbiota, Live-jslm [FMBL]) for Preventing Recurrent Clostridioides difficile Infection in the US.

INTRODUCTION: Patients with Clostridioides difficile infection (CDI) often experience recurrences (rCDI), which are associated with high morbidity, mortality, and healthcare expenditures. REBYOTA™ (fecal microbiota, live-jslm [FMBL]) is a microbiota-based live biotherapeutic approved for the prevention of rCDI following antibiotic treatment for rCDI. We quantified the budget impact of FMBL during the first 3 years following introduction from a third-party US payer perspective. METHODS: A decision-tree model was used to estimate the budget impact of one-course FMBL by comparing costs under the scenario with FMBL to the scenario without FMBL (standard of care) in patients with one or more (≥ 1) recurrences after a primary episode of CDI and had completed ≥ 1 round of antibiotic treatments. Drug costs, rCDI-related medical costs, and budget impact over 1-3 years were estimated in 2022 US dollars. One-way sensitivity analyses were performed. RESULTS: For an insurance plan with a population size of 1,000,000, 468 patients per year were estimated to have ≥ 1 rCDI. The budget impact of one-course FMBL at $9000/course was cost-saving at an¼ average of -$0.0039 on a per-member-per-month (PMPM) basis, an average of -$8.30 on a per-treated-member-per-month (PTMPM) basis, and a total of -$139,865 on a plan level assuming 5%, 15%, and 20% of patients receive FMBL over 1-3 years, respectively. The scenario with FMBL entry was associated with higher drug costs (difference at $0.0474 PMPM; $101.26 PTMPM; $1,706,445 total plan) and lower rCDI-related medical costs (difference at -$0.0513 PMPM; -$109.56 PTMPM; -$1,846,309 total plan). The budget impact of FMBL in patients at first rCDI was cost-saving at -$0.0139 PMPM, -$84.78 PTMPM, corresponding to an annual savings of $500,022. CONCLUSIONS: FMBL has a cost-saving budget impact for a US payer, with higher initial drug costs being offset by savings in rCDI-related medical costs. Greater cost saving was found in patients at first recurrence.

Impact on hospitalizations of long-term versus short-term therapy with sodium zirconium cyclosilicate during routine outpatient care of patients with hyperkalemia: the recognize I study.

BACKGROUND: Hyperkalemia is associated with increased healthcare resource utilization (HRU). This study evaluated the impact of sodium zirconium cyclosilicate (SZC) use on HRU in outpatients with hyperkalemia. RESEARCH DESIGN AND METHODS: A retrospective noncomparative study using claims data from the HealthVerity warehouse, which included outpatients in the United States who initiated SZC between January and December 2019 (index date) with ≥6 months' continuous coverage before (baseline) and after (follow-up) the index date (total coverage of 12 months). The study aimed to describe HRU with long-term and short-term SZC (defined as >90 and ≤90 days' supply, respectively, during 180 days' follow-up) and identify characteristics associated with long-term versus short-term therapy. RESULTS: Of 1153 patients, 748 (64.9%) received short-term and 405 (35.1%) received long-term therapy. During follow-up, lower proportions of patients on long-term versus short-term therapy had hyperkalemia-related hospitalizations (10.1% vs 15.1%; P < 0.05) and all-cause hospitalizations (22.5% vs 29.3%; P < 0.05). Hyperkalemia-related and all-cause hospitalization proportions were 33.0% and 23.3% lower, respectively. Predictors of long-term therapy included stage 3 chronic kidney disease. CONCLUSIONS: Approximately one-third of patients with hyperkalemia received long-term SZC therapy. Hyperkalemia-related and all-cause hospitalization proportions were lower with long-term therapy, although further confirmatory studies are needed.

Real-world outcomes associated with vonoprazan-based versus proton pump inhibitor-based therapy for Helicobacter pylori infection in Japan.

Background: Japanese guidelines recommend triple therapy with vonoprazan or a proton pump inhibitor (PPI) in combination with antibiotics to treat Helicobacter pylori (H. pylori) infection. While studies have shown improved eradication rates and reduced costs with vonoprazan versus PPIs, there is little data describing healthcare resource use (HCRU) and treatment patterns. Objectives: To compare patients treated with a vonoprazan-based or PPI-based regimen for H. pylori infection in Japan in terms of their characteristics, HCRU, healthcare costs, clinical outcomes, and treatment patterns. Design: Retrospective matched cohort. Methods: We used data from the Japan Medical Data Center claims database (July 2014-January 2020) to identify adult patients with H. pylori infection and a first observed use of vonoprazan or a PPI in 2015 or later (index date). Patients prescribed a vonoprazan-based or a PPI-based regimen were matched 1:1 using propensity score matching. HCRU, healthcare costs, diagnostic tests, a proxy for H. pylori eradication (i.e. no triple therapy with amoxicillin in combination with metronidazole or clarithromycin >30 days after the index date), and second-line treatment were described during the 12-month follow-up period. Results: Among 25,389 matched pairs, vonoprazan-treated patients had fewer all-cause and H. pylori-related inpatient stays and outpatient visits than PPI-treated patients, resulting in lower all-cause healthcare costs [185,378 Japanese yen (JPY) versus 230,876 JPY, p < 0.001]. Over 80% of patients received a post-treatment test for H. pylori. Fewer vonoprazan-treated than PPI-treated patients subsequently received an additional triple regimen for H. pylori infection (7.1% versus 20.0%, p < 0.001) or a prescription for vonoprazan or a PPI as monotherapy (12.4% versus 26.4%, p < 0.001) between 31 days and 12 months after the index date. Conclusion: Patients with H. pylori infection who were treated with vonoprazan-based therapy had lower rates of subsequent H. pylori treatment, lower overall and H. pylori-related HCRU, and lower healthcare costs than patients treated with PPI-based therapy.
