Patient-centric care in myelodysplastic syndromes: A global systematic literature review and gap analysis.

BACKGROUND: Disease progression and poor prognosis in higher-risk (HR) myelodysplastic syndrome (MDS) create an urgent need for interventions to improve the patient care experience in this vulnerable population. Patient-centric physician-supported strategies in conjunction with emerging therapies can help advance overall care and improve outcomes. The objective of this study was to evaluate patient-centric care (PCC) in the treatment of HR-MDS and identify opportunities to develop strategies to address care gaps for an optimal patient care experience. METHODS: A global systematic literature review (SLR) was conducted by cross-referencing MDS/HR-MDS with PCC terms, using PubMed, Embase, and Cochrane Collaboration databases (2017-2022) in accordance with Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. RESULTS: In all, 59 MDS articles (45 empirical, 14 reviews) met the study inclusion criteria. Of these, 6 empirical articles focused on the HR-MDS population while none of the reviews did. Identified themes fell into 2 categories: health-related quality of life (HRQoL) and disparities. HRQoL was further categorized based on findings in the literature to include groupings of patient-reported outcomes (PROs), fatigue/frailty, and patient/preferences/treatment decisions/shared decision making (SDM). CONCLUSIONS: With new treatments potentially on the horizon for HR-MDS, a call to action is timely to address the overall lack of empirical PCC data. The patient-centric approach presents critical opportunities for integration of physician-supported strategies with more effective first-line therapies to help optimize the journey of patients with HR-MDS and ensure meaningful outcomes by reducing patient/caregiver burden, aligning with and respecting patient preferences, and including patients as active participants in their treatment.

Patient Experiences with Clostridioides difficile Infection and Its Treatment: A Systematic Literature Review.

INTRODUCTION: Clostridioides difficile infection (CDI) is a globally recognized cause of morbidity and mortality with devastating effects on health-related quality of life (HRQoL). The objective of this study was to conduct the first systematic literature review (SLR) to assess the humanistic burden of CDI on patient experiences, including HRQoL and related constructs, and attitudes towards treatment alternatives. METHODS: An SLR was conducted to identify peer-reviewed articles that assessed CDI, including recurrent CDI (rCDI), and patient-reported outcomes or HRQoL. PubMed, Embase, and the Cochrane Collaboration abstracting services were used to conduct literature searches from 2010 to 2021 in the English language. This SLR was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) criteria. RESULTS: Of 511 identified articles, 21 met study inclusion criteria. The SLR showed CDI has a devastating impact on patients' overall HRQoL that continues well beyond infection clearance. The impact of CDI on physical, emotional, social, and professional well-being rivaled abdominal symptoms of uncontrollable diarrhea, being worse for patients with rCDI. Patients with CDI feel isolated, depressed, lonely, and continue to be frightened of recurrences as well as being contagious to others. Most believe that they will never be free of CDI. CONCLUSION: CDI and rCDI are debilitating conditions affecting physical, psychological, social, and professional functioning of patients' HRQoL, even long after the event has occurred. The results of this SLR suggest that CDI is a devastating condition in need of better prevention strategies, improved psychological support, and treatments that address the microbiome disruption to break the cycle of recurrence. Additional safe and effective therapies are needed to address this unmet medical need.

Clostridioides difficile infection is a gut bacterial infection that can happen after a person has taken antibiotics to treat another infection. C. difficile infection can lead to other medical problems and death. This review of the literature aimed to understand how C. difficile infection (first, previous, and repeat occurrences), the severe diarrhea it causes, and available treatments (both old and new) for C. difficile infection can impact a person's quality of life, daily self-care activities, and attitudes toward treatment. Results from this review of 21 studies showed that C. difficile infection has a negative impact on the quality of life of patients, affecting their physical, mental, and social health. C. difficile infection also disrupted the professional lives of patients and their ability to perform work activities. This negative effect continued over time, long after the infection had cleared because patients feared it would come back again. Treating C. difficile infection improved quality of life. Findings suggest that C. difficile infection is a devastating condition that needs better prevention strategies, improved psychological support, and treatments that stop the cycle of repeated gut infections by restoring good gut flora.

Assessment of Quality of Life Among Patients With Recurrent Clostridioides difficile Infection Treated with Investigational Oral Microbiome Therapeutic SER-109: Secondary Analysis of a Randomized Clinical Trial.

Importance: Recurrent Clostridioides difficile infection (CDI) is a debilitating disease leading to poor health-related quality of life (HRQOL), loss of productivity, anxiety, and depression. The potential association of treatment with HRQOL has not been well evaluated. Objectives: To explore the association of SER-109 compared with placebo on HRQOL in patients with recurrent CDI up to week 8. Design, Setting, and Participants: This study was a secondary analysis of a randomized, double-blind, placebo-controlled trial that took place at 56 sites in the US and Canada from July 2017 to April 2020 and included 182 patients randomized to SER-109 or placebo groups. Interventions: SER-109 or placebo (4 capsules once daily for 3 days) following antibiotics for CDI. Main Outcomes and Measures: Exploratory analysis of HRQOL using the disease specific Clostridioides difficile Quality of Life Survey (Cdiff32) assessed at baseline, week 1, and week 8. Results: In this study, 182 patients (109 [59.9%] female; mean age, 65.5 [16.5] years) were randomized to SER-109 (89 [48.9%]) or placebo (93 [51.1%]) groups and were included in the primary and exploratory analyses. Baseline Cdiff32 scores were similar between patients in the SER-109 and placebo groups (52.0 [18.3] vs 52.8 [18.7], respectively). The proportion of patients with overall improvement from baseline in the Cdiff32 total score was higher in the SER-109 arm than placebo at week 1 (49.4% vs 26.9%; P = .012) and week 8 (66.3% vs 48.4%; P = .001).Greater improvements in total and physical domain and subdomain scores were observed in patients in the SER-109 group compared with placebo as early as week 1, with continued improvements observed at week 8. Among patients in the placebo group, improvements in HRQOL were primarily observed in patients with nonrecurrent CDI while patients in the SER-109 group reported improvements in HRQOL, regardless of clinical outcome. Conclusions and Relevance: In this secondary analysis of a phase 3 clinical trial, SER-109, an investigational microbiome therapeutic was associated with rapid and steady improvement in HRQOL compared with placebo through 8 weeks, an important patient-reported outcome. Trial Registration: ClinicalTrials.gov Identifier: NCT03183128.

A systematic review of real-world healthcare resource use and costs of Clostridioides difficile infections.

Objective: To conduct a systematic review of published real-world evidence describing the cost and healthcare resource use for Clostridiodes difficile infection (CDI) in the United States. Methods: A systematic literature review was conducted searching for terms for CDI and healthcare costs. Titles of articles and abstracts were reviewed to identify those that met study criteria. Studies were evaluated to examine overall design and comparison groups in terms of healthcare resource use and cost for CDI. Results: In total, 28 articles met the inclusion criteria. Moreover, 20 studies evaluated primary CDI or did not specify, and 8 studies1-8 evaluated both primary CDI and recurrent (rCDI). Data from Medicare were used in 6 studies. Nearly all studies used a comparison group, either controls without CDI (N = 20) or comparison between primary CDI and rCDI (N = 7). Two studies examined costs of rCDI by the number of recurrences. Overall, the burden of CDI is significant, with higher aggregate costs for patients with rCDI. Compared with non-CDI controls, hospital length of stay increased in patients with both primary and rCDI compared to patients without CDI. Patients with primary CDI cost healthcare systems $24,000 more than patients without CDI. Additionally, 2 studies that evaluated the impact of recurrence among those patients with an index case of CDI demonstrated significantly higher direct all-cause medical costs among those with rCDI compared to those without. Conclusion: CDI, and particularly rCDI, is a costly condition with hospitalizations being the main cost driver.

Validation of a Health-Related Quality of Life Questionnaire in Patients With Recurrent Clostridioides difficile Infection in ECOSPOR III, a Phase 3 Randomized Trial.

BACKGROUND: Debilitating symptoms of recurrent Clostridioides difficile infection (rCDI) often lead to long-term effects on health-related quality-of-life (HRQOL). In ECOSPOR III, SER-109, an investigational oral microbiome therapeutic, was superior to placebo in reducing rCDI. We investigated the validity, reliability, and responsiveness of a 32-item, CDI-specific questionnaire-the Clostridium difficile Quality of Life Survey (Cdiff32)-across mental, physical, and social domains in patients with rCDI. METHODS: In this post hoc analysis of a phase 3 clinical trial, 182 outpatients with rCDI completed Cdiff32 and EQ-5D at baseline and at 1 and 8 weeks. Cdiff32 was evaluated for item performance, internal reliability, and convergent validity. To assess known-groups validity, Cdiff32 scores were compared by disease recurrence status at week 1; internal responsiveness was evaluated in the nonrecurrent disease group by 8 weeks by means of paired t test. RESULTS: All 182 patients (mean age [standard deviation], 65.5 [16.5] years; 59.9% female) completed baseline Cdiff32. Confirmatory factor analysis identified 3 domains (physical, mental, and social relationships) with good item fit. High internal reliability was demonstrated (Cronbach α = 0.94 with all subscales >0.80). Convergent validity was evidenced by significant correlations between Cdiff32 subscales and EQ-5D (r = 0.29-0.37; P < .001). Cdiff32 differentiated patients by disease recurrence status at week 1 (effect sizes, 0.38-0.42; P < .05 overall), with significant improvement from baseline through week 8 in patients with nonrecurrent disease at week 1 (effect sizes, 0.75-1.02; P < .001 overall). CONCLUSIONS: Cdiff32 is a valid, reliable, and responsive disease-specific HRQOL questionnaire that is fit for purpose for interventional treatment trials. The significant improvement in patients with nonrecurrent disease by 8 weeks demonstrates the negative impact of rCDI on HRQOL.

HTA and economics in the United States: a systematic review of ICER reports to evaluate trends, identify factors associated with recommendations, and understand implications.

BACKGROUND: The Institute for Clinical and Economic Review (ICER) is a prominent health technology assessment (HTA) entity in the United States that considers costs and applies economic analyses to derive price-based recommendations. ICER continues to adjust its value framework, yet discussion persists regarding whether ICER methodologies align with established research standards. This work evaluates ICER assessments relative to those standards, providing a benchmark with the release of ICER's most recent value framework update. OBJECTIVES: To evaluate ICER economic assessments for trends, factors related to recommendations, and quality for use in U.S. decision making. METHODS: We evaluated all ICER final evidence reports published between 2006 and August 31, 2019, with regard to base-case result trends over time, pricing sources, comparator selection, analytic perspectives, model uncertainty, how modeling results aligned with ICER's determinations of value for money, and comparison of ICER methodological approaches with established modeling standards. Analyses were stratified by time period, where appropriate, to account for changes in ICER's framework over time. RESULTS: Of 58 ICER final evidence reports, 47 used the most commonly reported outcome (cost per quality-adjusted life-year [QALY]); ICER-developed models evaluated 131 interventions and comparators with 238 base-case results. Pricing sources for ICER reports became more standardized in 2017, although sources were not associated with the likelihood of falling below ICER's cost-effectiveness thresholds. In 30% of base-case analyses (n = 72), ICER did not use a clinical comparator, although reasonable treatments were available. In modified societal perspectives scenarios applied in later assessments, 75% of analyses (n = 76) included productivity but did not specify how it was quantified. Reports did not explain how sensitivity and scenario analyses were selected or implications of results. ICER value for money determinations generally aligned with cost-effectiveness results, although 2 of 33 (6%) interventions ranked as low value and 3 of 5 (60%) interventions ranked as low-moderate value, met a $150,000 per QALY threshold, and 14 of 37 (38%) moderate-value interventions exceeded this threshold; the most common rationale was related to national budget impact. CONCLUSIONS: While some progress has been made, further improvement is needed to ensure that ICER assessments address the most relevant questions for target audiences, adhere to established research standards, and are reported in a manner that can be readily interpreted and applied to policymaking. DISCLOSURES: No outside funding supported this study. The authors have nothing to disclose.

Feasibility of an online mindfulness program for stress management--a randomized, controlled trial.

BACKGROUND: Chronic stress affects many Americans. Stress management programs may be prohibitively expensive or have limited access. PURPOSE: This study aims to determine feasibility of an 8-week Internet-based stress management program (ISM) based on mindfulness principles in reducing stress in a 12-week, parallel, randomized, controlled trial. METHODS: Participants were randomly allocated to ISM, ISM plus online message board (ISM+), or control groups. Perceived stress, mindfulness, self-transcendence, psychological well-being, vitality, and quality of life were measured at baseline, week 8, and week 12 using standard validated questionnaires. RESULTS: ISM and ISM+ groups demonstrated statistically significant improvements compared with control on all measures except vitality and physical health. CONCLUSIONS: The ISM program effectively and sustainably reduced measures of stress. The magnitude of improvement is comparable to traditional mindfulness programs, although fewer participants were engaged. This feasibility study provides strong support for online stress management programs, which increase access at a fraction of cost of traditional programs.

Analysis of the costs and payments of a coordinated stroke center and regional stroke network.

BACKGROUND AND PURPOSE: An earlier study demonstrated significantly improved access, treatment, and outcomes after the implementation of a progressive, comprehensive stroke program at a tertiary care community hospital, Saint Luke's Neuroscience Institute (SLNI). This study evaluated the costs associated with implementing such a program. METHODS: Retrospective analysis of total hospital costs and payments for treating patients with ischemic stroke at SLNI (n=1570) as program enhancement evolved over time (2005, 2007, and 2010) and compared with published national estimates. Analyses were stratified by patient demographic characteristics, patient outcomes, treatments, time, and comorbidities. RESULTS: Controlling for inflation, there was no difference in SLNI total costs between 2005 and either 2007 or 2010, suggesting that while SLNI provided an increased level of services, any additional expenditures were offset by efficiencies. SLNI total costs were slightly lower than published benchmarks. Consistent with previous stroke care cost estimates, the median overall differential between total hospital costs and payments for all ischemic stroke cases was negative. CONCLUSIONS: SLNI total costs remained consistent over time and were slightly lower than previously published estimates, suggesting that a focused, streamlined stroke program can be implemented without a significant economic impact. This finding further demonstrates that providing comprehensive stroke care with improved access and treatment may be financially feasible for other hospitals.

Analysis of a coordinated stroke center and regional stroke network on access to acute therapy and clinical outcomes.

BACKGROUND AND PURPOSE: Compare access and outcomes in a tertiary care community hospital (Saint Luke's Neuroscience Institute) and its stroke network to hospitals in 3 national databases. METHODS: Retrospective analysis of ischemic stroke patients (2005, 2007, 2010) in Saint Luke's (n=1576), Get With The Guidelines-Stroke (n=423 809), Premier (n=91 598), and Merci Registry (n=966). Study measures were use of computed tomography scans and tissue plasminogen activator (tPA), symptomatic intracranial hemorrhage, discharge disposition, discharge National Institutes of Health Stroke Scale scores, and 90-day modified Rankin Scores. RESULTS: Saint Luke's increased access to care with higher tPA use than other hospitals (17.2% received intravenous tPA therapy compared with 5.8% at Get With The Guidelines-Stroke hospitals, P<0.001; 22.1% of Saint Luke's patients received tPA by any route compared with 3.5% of Premier patients, P<0.001). Use of intravenous tPA within 4.5 hours of onset was associated with more discharges to home (odds ratio, 2.123; 95% confidence interval, 1.394-3.246) and improved National Institutes of Health Stroke Scale scores (P=0.001). Saint Luke's patients also were more likely than those in other hospitals to receive computed tomography scans (99.4% vs 58.6% at Premier hospitals). Embolectomy at Saint Luke's was associated with better outcomes than peer hospitals, and treatment at Saint Luke's was independently associated with more discharges to home (odds ratio, 3.92; 95% confidence interval, 1.84-8.32). In 2010, symptomatic intracranial hemorrhages after tPA therapy was similar for Saint Luke's patients and Premier patients (2.2% vs 1.5%; P=0.590). CONCLUSIONS: Regionally coordinated stroke programs can substantially improve access and patient outcomes.

Is treatment of postherpetic neuralgia in the community consistent with evidence-based recommendations?

Few studies have examined the extent to which treatment of patients with neuropathic pain in the community is consistent with evidence-based treatment recommendations. U.S. health care claims were used to identify patients who received a diagnosis of postherpetic neuralgia (PHN). The initial pharmacologic treatments and changes to these treatment regimens were categorized according to the International Association for the Study of Pain Neuropathic Pain Special Interest Group recommendations for first-, second-, and third-line treatment of neuropathic pain. The results indicated that the treatment of PHN was only partially consistent with these treatment recommendations. Of the patients diagnosed with PHN who were not already on a specified treatment, 70% began treatment with either a first-, second-, or third-line treatment or a not-recommended treatment, and 30% did not begin treatment with any of these medications. Only one-quarter of patients began treatment with a first-line medication, the same percentage that began treatment with either a third-line medication or a not-recommended treatment. There was a wide range of initial treatment durations, but the means and medians suggest that patients and clinicians often decide to change the initial treatment within 2 months, either by discontinuing it, replacing it with a new medication, or adding a new medication. Although there were generally shorter treatment durations with opioid analgesics and tramadol, these medications were more frequently used in beginning treatment than the other treatments. The results suggest that a considerable number of patients with PHN in the community are not receiving evidence-based treatment.

Healthcare utilization in people with postherpetic neuralgia and painful diabetic peripheral neuropathy.

OBJECTIVES: To determine and compare healthcare utilization and costs for younger and older adults with postherpetic neuralgia (PHN) and painful diabetic peripheral neuropathy (DPN). DESIGN: Retrospective cohort analysis. SETTING: Inpatient and outpatient care. PARTICIPANTS: Patients with PHN or painful DPN were selected from administrative databases of healthcare claims and matched to controls who had a diagnosis of herpes zoster without persistent pain or a diagnosis of diabetes mellitus without neurological complications using propensity scores for demographic and clinical factors. MEASUREMENTS: Excess per-person utilization and costs attributable to PHN and painful DPN were calculated for diagnostic procedures, medications, and interventional treatments related to neuropathic pain. RESULTS: In both groups, the patterns of significant excess per-patient utilization and excess per-patient costs were similar for diagnostic procedures, medications, and interventional treatments, but patterns of utilization and costs of these procedures and treatments differed depending on age and the specific condition examined. CONCLUSION: The results contribute to and expand current knowledge of the excess healthcare usage and costs of two prevalent peripheral neuropathic pain conditions and can be used in future studies of the cost-effectiveness of treatment and preventive interventions.

Cost-effectiveness analysis of a new 8% capsaicin patch compared to existing therapies for postherpetic neuralgia.

OBJECTIVE: The purpose of this study was to compare the cost effectiveness of a new 8% capsaicin patch, compared to the current treatments for postherpetic neuralgia (PHN), including tricyclic antidepressants (TCAs), topical lidocaine patches, duloxetine, gabapentin, and pregabalin. METHODS: A 1-year Markov model was constructed for PHN with monthly cycles, including dose titration and management of adverse events. The perspective of the analysis was from a payer perspective, managed-care organization. Clinical trials were used to determine the proportion of patients achieving at least a 30% improvement in PHN pain, the efficacy parameter. The outcome was cost per quality-adjusted life-year (QALY); second-order probabilistic sensitivity analyses were conducted. RESULTS: The effectiveness results indicated that 8% capsaicin patch and topical lidocaine patch were significantly more effective than the oral PHN products. TCAs were least costly and significantly less costly than duloxetine, pregabalin, topical lidocaine patch, 8% capsaicin patch, but not gabapentin. The incremental cost-effectiveness ratio for the 8% capsaicin patch overlapped with the topical lidocaine patch and was within the accepted threshold of cost per QALY gained compared to TCAs, duloxetine, gabapentin, and pregablin. The frequency of the 8% capsaicin patch retreatment assumption significantly impacts its cost-effectiveness results. There are several limitations to this analysis. Since no head-to-head studies were identified, this model used inputs from multiple clinical trials. Also, a last observation carried forward process was assumed to have continued for the duration of the model. Additionally, the trials with duloxetine may have over-predicted its efficacy in PHN. Although a 30% improvement in pain is often an endpoint in clinical trials, some patients may require greater or less improvement in pain to be considered a clinical success. CONCLUSIONS: The effectiveness results demonstrated that 8% capsaicin and topical lidocaine patches had significantly higher effectiveness rates than the oral agents used to treat PHN. In addition, this cost-effectiveness analysis found that the 8% capsaicin patch was similar to topical lidocaine patch and within an accepted cost per QALY gained threshold compared to the oral products.

Impact of postherpetic neuralgia and painful diabetic peripheral neuropathy on health care costs.

UNLABELLED: Knowledge of the health care costs associated with neuropathic pain is limited. Existing studies have not directly compared the health care costs of different neuropathic pain conditions, and patients with neuropathic pain have not been compared with control subjects with the same underlying conditions (for example, diabetes). To determine health care costs associated with postherpetic neuralgia (PHN) and painful diabetic peripheral neuropathy (DPN), patients with these conditions were selected from 2 different administrative databases of health care claims and respectively matched to control subjects who had a diagnosis of herpes zoster without persisting pain or a diagnosis of diabetes without neurological complications using propensity scores for demographic and clinical factors. Total excess health care costs attributable to PHN and painful DPN and excess costs for inpatient care, outpatient/professional services, and pharmacy expenses were calculated. The results indicated that the annual excess health care costs associated with peripheral neuropathic pain in patients of all ages range from approximately $1600 to $7000, depending on the specific pain condition. Total excess health care costs associated with painful DPN were substantially greater than those associated with PHN, which might reflect the great medical comorbidity associated with DPN. PERSPECTIVE: The data demonstrate that the health care costs associated with 1 peripheral neuropathic pain condition cannot be extrapolated to other neuropathic pain conditions. The results also increase understanding of the economic burden of PHN and painful DPN and provide a basis for evaluating the impact on health care costs of new interventions for their treatment and prevention.

The identification of benefit in medical intervention: an overview and suggestions for process.

Benefit and risk assessments are not only important to regulatory authorities but also important to the providers, patients, pharmaceutical industry, and payers. In order for patients and providers to continue to have access to new innovative medicines, which have some level of inherent risk, it is critical to have a systematic and balanced focus on understanding the safety risks and benefits to the patient during drug development, at the time of approval and postmarketing. There has been a significant amount of activity around efforts to improve the ability to assess risks in the postmarketing environment. However, there is no widely accepted, systematic approach or process for the ongoing evaluation of benefit. This article introduces 4 critical components in the process of identifying and assessing benefit with a goal of providing a framework that is transparent, comprehensive, applicable to various perspectives, and simple to communicate and implement. We propose the development of a catalog applied to a particular disease to identify the optimal data sources and methods to address the interests of a given perspective. Two key resources will need to be developed to support the catalog development: (1) a summary of benefit measures and preferences by disease and from various perspectives and (2) an investment in a simple visual communication mechanism with minimal statistical language. As the emphasis is on transparency, relevance, applicability, and communication, this approach to assessing benefit should maximize the impact of these data to all stakeholders and decision makers.

Immunologic and virologic consequences of temporary antiretroviral treatment interruption in clinical practice.

To determine the long-term immunologic and virologic effects of antiretroviral treatment interruptions, a retrospective analysis of an ongoing observational database was performed at a university HIV clinic. All patients who began highly active antiretroviral therapy (HAART) after January 1, 1996 and (1) were HAART experienced for >/=90 days, (2) had a treatment interruption (TI) for >/=30 days, (3) resumed HAART for >/=30 days, and (4) had CD4(+) cell counts performed pre- and post-TI were included. Main outcome measures included the following: Immunologic success was defined as a post-TI CD4(+) cell count >90% of the pre-TI CD4(+) cell count (post-TI/pre-TI, >90%). Virologic success was defined as a post-TI viral load (VL) less or equal to twice the pre-TI VL (post-TI/pre-TI,
