ABSTRACT

BACKGROUND: HOCl (eg, pHAp) preserved solutions have antimicrobial properties and are considered safe and effective for wound management. NPWTi-d (or NPWTi) is an established adjunctive wound modality for a variety of wound etiologies in various anatomic locations in which an instillate solution dwells on the surface of the wound to assist in wound bed preparation. A variety of solutions have been used, including 0.9% normal saline wound cleansers and antiseptics. pHAp is growing in popularity as the solution of choice for NPWTi-d. OBJECTIVE: To evaluate consensus statements on the use of NPWTi-d with pHAp. METHODS: A 15-member multidisciplinary panel of expert clinicians in the United States, Canada, and France convened in person in April 2023 in Washington, D.C. and/or corresponded later to discuss 10 statements on the use of pHAp with NPWTi-d. The panelists then replied "agree" or "disagree" to each statement and had the option to provide comments. RESULTS: Ten consensus statements are presented, along with the proportion of agreement or disagreement and summary comments. Although agreement with the statements on NPWTi-d with pHAp varied, the statements appear to reflect individual preferences for use rather than concerns about safety or efficacy. CONCLUSION: The consensus indicates that NPWTi-d with pHAp can have a beneficial effect in wound care.

ABSTRACT

BACKGROUND: Past clinical trial findings suggest that the availability of regadenoson in a nuclear imaging center may affect real-world center practices related to the transition of patients from an inadequate exercise stress test (EST) to a pharmacological stress agent (PSA). METHODS AND RESULTS: This was a cross-sectional study using one-on-one telephone interviews with nuclear imaging center staff to facilitate survey development, followed by an online survey to evaluate patterns and processes around use of PSAs during single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI) in patients with inadequate ESTs. Of the 50 participants, 35 (70%) used only regadenoson, 3 (6%) only adenosine, 3 (6%) regadenoson and adenosine, 7 (14%) regadenoson and dipyridamole, and 2 (4%) all 3 agents for converting patients from an inadequate EST to a PSA. Nearly all centers (94%) used protocols to guide conversions. Of 12 centers using > 1 PSA, 11 reported regadenoson to be the most preferred PSA. Total staff time required from PSA transition to post-test monitoring was shortest for regadenoson. CONCLUSIONS: Compared to adenosine and dipyridamole, regadenoson is preferred by nuclear imaging center staff and associated with operational efficiencies after inadequate EST in real-world practice SPECT-MPI.

ABSTRACT

OBJECTIVE: To provide cost estimates for chronic kidney disease (CKD) management and major CKD complications among patients with CKD and type 2 diabetes (T2D). STUDY DESIGN: A retrospective cohort study of 52,599 adults with CKD and T2D using Optum Clinformatics claims data from 2014 to 2019. METHODS: Medical costs associated with CKD management, renal replacement therapies (RRTs), major CKD complications (eg, myocardial infarction, stroke, heart failure, atrial fibrillation, and hyperkalemia), and death were estimated using generalized estimating equations adjusting for baseline demographics, complications, and medical costs. Costs for CKD management, RRT, and major CKD complications were assessed in 4-month cycles. Mortality costs were assessed in the month before death. RESULTS: The estimated 4-month CKD management costs ranged from $7725 for stage I to II disease to $11,879 for stage V (without RRT), with high additional costs for dialysis and kidney transplantation ($87,538 and $124,271, respectively). The acute event costs were $31,063 for heart failure, $21,087 for stroke, and $21,016 for myocardial infarction in the first 4 months after the incident event, which all decreased substantially in subsequent 4-month cycles. The acute event costs of atrial fibrillation and hyperkalemia were $30,500 and $31,212 with hospitalization, and $5162 and $1782 without. The costs associated with cardiovascular-related death, renal-related death, and death from other causes were $17,031, $12,605, and $9900, respectively. CONCLUSIONS: Management of CKD and its complications incurs high medical costs for patients with CKD and T2D. Results from this study can be used to quantify the economic profile of emerging treatments and inform decision-making.

ABSTRACT

Gene therapy for hemophilia is designed to produce health gains for patients over many years. Rewarding that value creation on the basis of a one-time treatment implies a large upfront cost. This cost can only be justified by long-term health benefits and being cost-effective compared with conventional treatments. Yet, uncertainties about the long-term benefits make it challenging to assess clinical and economic value of gene therapies at launch. We identify and discuss key methodological challenges in assessing the value of gene therapy for hemophilia, including the immaturity of evidence on the durability of benefits, lack of definition and valuation of cure for chronic diseases, absence of randomized controlled trials, limitations of traditional quality of life measures in hemophilia, approach for qualifying cost-savings compared with current treatments, and choice of perspective. The Institute for Clinical and Economic Review has developed a framework for assessing single or short-term therapies (ICER-SST) and has applied it in hemophilia. After reviewing this framework and its application, we recommend the following when assessing the value of hemophilia gene therapies: (1) leveraging expert clinical opinion to justify assumptions on the durability of benefits; (2) using external synthetic controls and lead-in, self-controlled trials to assess comparative effectiveness; (3) addressing limitations of traditional quality of life measures through the use of modified utility collection approaches; (4) adjusting cost offsets from gene therapies with caution; (5) considering outcome-based contracting to address uncertainties about prices and long-term outcomes; and (6) presenting societal and healthcare system perspectives in parallel.

ABSTRACT

BACKGROUND: Advanced cholangiocarcinoma (CCA) is associated with considerable morbidity and mortality. Novel second-line treatments for advanced CCA underscore the need to understand treatment patterns and economic burden of illness in clinical practice. METHODS: This retrospective, claims-based study using Optum's de-identified Clinformatics® Data Mart Database [2007-2019] selected patients with CCA who experienced failure of a line of therapy containing either gemcitabine or fluorouracil. The index date was defined based on evidence of treatment failure: date of last administration of the gemcitabine- or fluorouracil-based regimen plus 28 days, or initiation date of the next-line systemic therapy. Treatment patterns, healthcare resource use (HRU), costs, and survival were assessed during the follow-up period (index until death or end of eligibility). RESULTS: A total of 1,298 patients met inclusion criteria and had a mean age of 69.1 years. There were 958 patients (73.8%) with intrahepatic and 275 patients (21.2%) with extrahepatic CCA. Average follow-up was 7.5 months. Almost 40% of patients did not receive another line of therapy after the index date. Among the 784 patients who received another line of therapy, 40.3% used fluorouracil-based therapy, 30.7% used gemcitabine-based therapy, and 29.3% used capecitabine-based therapy. Total mean per patient per month CCA-related healthcare costs were $7,743, with medical services ($6,685) a larger driver of monthly costs relative to treatment costs ($1,058). Median overall survival (OS) was 5.3 months among all patients. CONCLUSIONS: Many patients with advanced CCA do not initiate additional therapy after failure of gemcitabine or fluorouracil treatment, and there is considerable variation in treatments among those who do. This study highlights the high costs and unmet need for a standard of care in this patient population.

ABSTRACT

INTRODUCTION: Erenumab, a first-in-class monoclonal antibody targeting the calcitonin gene-related peptide pathway, was approved by the US Food and Drug Administration in 2018 for the prevention of migraine in adults. There is limited data available on its impact in real-world settings. The study aim was to characterize the real-world treatment profiles, clinical outcomes, and healthcare resource utilization of patients prescribed erenumab from select major US headache centers. METHODS: A retrospective chart review of patients with migraine treated with erenumab for at least 3 months across five major headache centers was conducted. Data was collected from patient charts between April 2019 and April 2020 and included patient and clinical characteristics, migraine medication use, and outpatient visits. The date of the first prescription fill of erenumab was defined as the index date. The baseline period comprised the 3 months prior to the index date and the study period comprised the at least 3 months on erenumab treatment. RESULTS: Data from a total of 1034 patients with chronic migraine with a mean of 9.3 months of erenumab treatment were analyzed. Patients were on average 48 years old, 86% were female, and 79% were white. Patients had a mean of 5 preventive treatment failures prior to erenumab initiation. Patients used a mean of 2 preventive treatments (excluding erenumab) and 2 acute treatments during baseline and study periods. Among patients with effectiveness data, 45% of patients had improvement in physician-reported migraine severity and 35% experienced at least 50% reduction in mean headache/migraine days per month. The average number of monthly outpatient visits was 0.43 and 0.30 before and after erenumab initiation, respectively. CONCLUSION: In this predominantly refractory chronic migraine population treated in select headache centers, patients had fewer headache/migraine days per month and outpatient visits after initiating erenumab. However, patients largely continued to be managed via a polypharmacy approach after erenumab initiation.

ABSTRACT

BACKGROUND: Pressure ulcers/injuries (PU/Is) negatively affect patients by causing pain and increasing morbidity and mortality risks. Care teams have a heightened sense of awareness of the condition and may feel confident in their ability to appropriately identify and manage PU/Is, but the potential for, and consequences of, a misdiagnosis always should be considered. PURPOSE: The purpose of this compendium is to describe and illustrate conditions that may mimic PU/Is. METHODS: Advanced practice wound care nurses were asked to identify and describe conditions that may mimic PU/Is. Permission was obtained from all patients to use their cases and photos in this article. RESULTS: Sixteen (16) different skin and wound presentations resulting from vascular diseases, systemic infections, trauma, cancer, autoimmune disorders, coagulopathies, and multisystem organ dysfunction were identified and described. CONCLUSION: A complete patient history and assessment will help prevent misidentification of the etiology of a skin lesion or wound and misdiagnosis of these lesions as PU/Is.

ABSTRACT

SUMMARY: The use of negative-pressure wound therapy (NPWT) has become an established therapy for wound management. There have been many advancements in the technology of NPWT including NPWT with instillation and dwell (NPWTi-d). NPWTi-d promotes wound healing by wound cleansing, irrigation, and nonexcisional debridement. NPWTi-d has been shown in comparative clinical studies to decrease the time to definitive wound healing and length of hospitalization. NPWTi-d-using a reticulated open-cell foam dressing with "through" holes (ROCF-CC)-has been postulated to facilitate solubilization, detachment, and elimination of infectious materials, such as slough and thick exudate, before or after operative debridement, and in cases where surgical debridement is not an option. The authors provide an overview on the use of NPWTi-d by reviewing the components of the system, proposed mechanism of action, clinical outcomes, and current consensus guidelines for its utilization.

ABSTRACT

The use of negative pressure wound therapy with instillation and dwell time (NPWTi-d) has gained wider adoption and interest due in part to the increasing complexity of wounds and patient conditions. Best practices for the use of NPWTi-d have shifted in recent years based on a growing body of evidence and expanded worldwide experience with the technology. To better guide the use of NPWTi-d with all dressing and setting configurations, as well as solutions, there is a need to publish updated international consensus guidelines, which were last produced over 6 years ago. An international, multidisciplinary expert panel of clinicians was convened on 22 to 23 February 2019, to assist in developing current recommendations for best practices of the use of NPWTi-d. Principal aims of the meeting were to update recommendations based on panel members' experience and published results regarding topics such as appropriate application settings, topical wound solution selection, and wound and patient characteristics for the use of NPWTi-d with various dressing types. The final consensus recommendations were derived based on greater than 80% agreement among the panellists. The guidelines in this publication represent further refinement of the recommended parameters originally established for the use of NPWTi-d. The authors thank Karen Beach and Ricardo Martinez for their assistance with manuscript preparation.

ABSTRACT

OBJECTIVE: To compare health care resource utilization and costs in veterans with schizophrenia treated with paliperidone palmitate (PP) versus oral atypical antipsychotics (OAAs). METHODS: A retrospective longitudinal study was conducted using electronic health record data from the Veterans Health Administration. Veterans with schizophrenia (identified using ICD-9-CM 295.x) initiating PP or OAAs between January 2010 and October 2014, with ≥ 12 months of benefits enrollment prior to treatment initiation and ≥ 6 months of enrollment after treatment initiation, and with ≥ 1 Global Assessment of Functioning measurement at baseline were included. Inverse probability of treatment weighted regression models were used to estimate incidence rate ratios (IRRs) and cost differences (CDs) for the impact of PP versus OAAs on health care resource utilization and costs. RESULTS: Among 10,290 eligible veterans, 2,285 and 8,005 were initiated on PP and OAAs, respectively. After adjustment, PP was associated with less frequent all-cause inpatient hospitalizations (IRR = 0.89, P < .001) and more frequent mental health intensive case management visits (IRR = 1.81, P < .001) compared to OAAs. PP treatment was associated with higher likelihood of increased income (odds ratio [OR] = 1.20, P = .027) and lower likelihood of homelessness (OR = 0.82, P < .001). While mean annual pharmacy and outpatient costs were higher among PP users (CD = $3,417 pharmacy, $2,527 outpatient, P < .001), mean annual inpatient costs were lower (CD = -$14,456, P < .001), resulting in average annual total health care (medical and pharmacy) cost savings associated with PP (CD = -$8,511, P = .012) relative to OAAs. CONCLUSIONS: PP treatment was associated with significantly lower total health care costs attributable to reduced inpatient admissions compared to OAAs. Higher mental health intensive case management participation among PP users may have contributed to the differences observed.

ABSTRACT

This study evaluated the incremental healthcare costs associated with Fragile X syndrome (FXS) for patients and their caregivers. Using administrative healthcare claims data (1999-2012), subjects with ≥ 1 FXS diagnosis (ICD-9-CM: 759.83) were matched 1:5 with non-FXS controls using high-dimensional propensity scores. Costs and resource utilization were examined. Among employees, payment for disability leave and absenteeism were also examined. We identified 590 FXS and 2,950 non-FXS individuals along with 647 and 2,611 caregivers, respectively. FXS patients and their caregivers experienced higher all-cause direct costs compared to control cohorts (total[SD]: $14,677[46,752] vs. $6,103[26,081]; $5,259[19,360] vs. $2,120[6,425], respectively, p < 0.05). Employed FXS patients and caregivers had higher indirect costs compared to their controls (total[SD]: $4,477[5,161] vs. $1,751[2,556]; $2,641[4,238] vs. $1,211[1,936], respectively, p < 0.05).

ABSTRACT

Ibrutinib is a first-in-class oral covalent inhibitor of Bruton's tyrosine kinase that has demonstrated clinical benefit for many patients with B cell malignancies. Positive results in initial trials led the U.S. Food and Drug Administration to grant ibrutinib three breakthrough therapy designations for mantle cell lymphoma (MCL), del17p chronic lymphocytic leukemia (CLL), and Waldenström's macroglobulinemia (WM). Ibrutinib was approved for these three cancers within 14 months of the original U.S. approval. Additionally, ibrutinib is approved for patient subsets with MCL and/or CLL in >45 other countries. Via a unique mechanism of action, ibrutinib inhibits B cell signaling pathways that regulate the survival, proliferation, adhesion, and homing of cancerous cells. This marks a paradigm shift from the conventional cytotoxic chemotherapy approach to treating B cell malignancies. Ibrutinib continues to be evaluated across a range of B cell malignancies, either as single-agent therapy or in combination with other therapies, and continues to transform the lives of these patients.

ABSTRACT

BACKGROUND: Psoriasis's effect on diabetes onset is well documented, but its effect on course of diabetes is poorly understood. OBJECTIVE: We sought to compare risks of developing microvascular and macrovascular complications between diabetic patients with and without psoriasis. METHODS: Adults with 2 or more diabetes diagnoses selected from MarketScan databases (Truven Health Analytics Inc, Ann Arbor, MI) (2000-2006) were classified into 2 cohorts: 2 or more psoriasis diagnoses and without psoriasis diagnosis. Patients with psoriasis were matched using propensity score, and exactly matched using age, sex, and diabetes characteristics with patients without psoriasis. Outcomes were compared between cohorts using Cox regression models. RESULTS: In all, 6164 diabetic patients with psoriasis (27% moderate to severe) were matched to 6164 diabetic patients without psoriasis. Patients with psoriasis were significantly more likely to develop microvascular events than patients without psoriasis overall (hazard ratio [HR] 1.14, P < .001) and by psoriasis severity (mild: HR 1.13, P = .004; moderate to severe: HR 1.16, P = .038). Risk of macrovascular events was higher for patients without psoriasis overall (HR 1.13, P = .001) and those with mild psoriasis (HR 1.15, P = .003), but not for moderate to severe cases (HR 1.10, P = .210). LIMITATIONS: Psoriasis to diabetes association may be underestimated. CONCLUSION: Among diabetic patients, psoriasis is generally associated with higher rates of microvascular and macrovascular complications. Greater psoriasis severity did not increase risk of diabetic complications.

ABSTRACT

OBJECTIVES: To assess the association between medical costs and persistence with beta blockers among hypertensive patients, and to quantify persistence related medical cost differences with nebivolol, which is associated with improved tolerability, versus other beta blockers. METHODS: Adults who initiated hypertension treatment with a beta blocker were identified from the MarketScan * claims database (2008-2012). Patients were classified based on their first beta blocker use: nebivolol, atenolol, carvedilol, metoprolol, and other beta blockers. Patients with compelling indications for atenolol, carvedilol or metoprolol (acute coronary syndrome and congestive heart failure) were excluded. Patients enrolled in health maintenance organization or capitated point of service insurance plans were also excluded. Persistence was defined as continuous use of the index drug (<60 day gap). The average effect of persistence on medical costs (2012 USD) was estimated using generalized linear models (GLMs). Regression estimates were used to predict medical cost differences associated with persistence between nebivolol and the other cohorts. RESULTS: A total of 587,424 hypertensive patients met the inclusion criteria. Each additional month of persistence with any one beta blocker was associated with $152.51 in all-cause medical cost savings; continuous treatment for 1 year was associated with $1585.98 in all-cause medical cost savings. Patients treated with nebivolol had longer persistence during the 1 year study period (median: 315 days) than all other beta blockers (median: 156-292 days). Longer persistence with nebivolol translated into $305.74 all-cause medical cost savings relative to all other beta blockers. LIMITATIONS: The results may not be generalizable to hypertensive patients with acute coronary syndrome or congestive heart failure. CONCLUSIONS: Longer persistence with beta blockers for the treatment of hypertension was associated with lower medical costs. There may be greater cost savings due to better persistence with nebivolol than other beta blockers.

ABSTRACT

OBJECTIVE: This study aims to develop and validate a stroke risk model incorporating pulse pressure (PP) as a potential risk factor. Recent evidence suggests that PP, defined as the difference between systolic blood pressure (SBP) and diastolic blood pressure (DBP), could be an incremental risk factor beyond SBP. METHODS: Electronic health records (EHRs) of hypertensive patients from a US integrated health delivery system were analyzed (January 2004 to May 2012). Patients with ≥ 1 PP reading and ≥ 6 months of observation prior to the first diagnosis of hypertension were randomly split into development (two-thirds of sample) and validation (one-third of sample) datasets. Stroke events were identified using ICD-9-CM 433.xx-436.xx. Cox proportional hazards models assessed time to first stroke event within 3 years of first hypertension diagnosis based on baseline risk factors, including PP, age, gender, diabetes, and cardiac comorbidities. The optimal model was selected using the least absolute shrinkage and selection operator (LASSO); performance was evaluated by the c-statistic. RESULTS: Among 34,797 patients selected (mean age 59.3 years, 48% male), 4272 patients (12.3%) had a stroke. PP was higher among patients who developed stroke (mean [SD] PP, stroke: 02.0 [15.3] mmHg; non-stroke: 58.1 [14.0] mmHg, p < 0.001). The best performing risk model (c-statistic, development: 0.730; validation: 0.729) included PP (hazard ratio per mmHg increase: 1.0037, p < 0.001) as a significant risk factor. LIMITATIONS: This study was subject to limitations similar to other studies using EHRs. Only patient encounters occurring within the single healthcare network were captured in the data source. Though the model was tested internally, external validation (using a separate data source) would help assess the model's generalizability and calibration. CONCLUSIONS: This stroke risk model shows that greater PP is a significant predictive factor for increased stroke risk, even in the presence of known risk factors. PP should be considered by practitioners along with established risk factors in stroke treatment strategies.

ABSTRACT

OBJECTIVE: Treatment options for recurrent or progressive hormone receptor-positive (HR+) advanced breast cancer include chemotherapy and everolimus plus exemestane (EVE + EXE). This study estimates the costs of managing adverse events (AEs) during EVE + EXE therapy and single-agent chemotherapy in Western Europe. METHODS: An economic model was developed to estimate the per patient cost of managing grade 3/4 AEs for patients who were treated with EVE + EXE or chemotherapies. AE rates for patients receiving EVE + EXE were collected from the phase III BOLERO-2 trial. AE rates for single-agent chemotherapy, capecitabine, docetaxel, or doxorubicin were collected from published clinical trial data. AEs with at least 2% prevalence for any of the treatments were included in the model. A literature search was conducted to obtain costs of managing each AE, which were then averaged across Western European countries (when available). Per patient costs for managing AEs among patients receiving different therapies were reported in 2012 euros (€). RESULTS: The EVE + EXE combination had the lowest average per patient cost of managing AEs (€730) compared to all chemotherapies during the first year of treatment (doxorubicin: €1230; capecitabine: €1721; docetaxel: €2390). The most costly adverse event among all patients treated with EVE + EXE was anemia (on average €152 per patient). The most costly adverse event among all patients treated with capecitabine, docetaxel, or doxorubicin was lymphocytopenia (€861 per patient), neutropenia (€821 per patient), and leukopenia (€382 per patient), respectively. CONCLUSIONS: The current model estimates that AE management during the treatment of HR+ advanced breast cancer will cost one-half to one-third less for EVE + EXE patients than for chemotherapy patients.

ABSTRACT

BACKGROUND: Treatment protocols and prices of antiretroviral therapy (ART) have changed over time. Yet, limited data exist to evaluate the impact of these changes on patient outcomes and treatment costs in resource-poor settings. METHODS: We compared patient-level data on outcomes, utilization, and cost for the first 2 years of ART for a cohort of adult patients initiating ART in 2003-2004 and a cohort initiating ART in 2006-2008 at the Haitian Group for the Study of Kaposi's Sarcoma and Opportunistic Infections clinic (GHESKIO) in Port-au-Prince, Haiti. Costs were measured from the health center perspective. Multivariate analyses were conducted to account for the potential impact of differences in disease severity at baseline. RESULTS: With the exclusion of patients who transferred care, 92% (167/181) of patients in the 2006-2008 cohort and 75% (150/200) in the 2003-2004 cohort were alive and in care at the end of the study period. The mean cost per patient for the 2-year study period was US$723 for the 2006-2008 cohort vs. US$1191 for the 2003-2004 cohort, a cost difference of US$468 (P < 0.0001). The mean cost per patient alive and in care at the end of the 2-year study period was US$744 for the 2006-2008 cohort vs. US$1489 for the 2003-2004 cohort (P < 0.0001). CONCLUSIONS: HIV treatment outcomes in Haiti have improved over time while treatment costs declined by over 50% per patient alive and in care at the end of the 2-year study period. The major drivers in the reduction of treatment costs were the lower price of ART, lower costs for laboratory testing, and lower overhead costs.

ABSTRACT

BACKGROUND: Although the last decade has seen increased access to antiretroviral therapy across the developing world, widespread food insecurity and undernutrition continue to compromise an effective response to the AIDS epidemic. Limited evidence exists on the potential benefit of food security and nutrition interventions to people living with HIV (PLHIV). METHODS: We capitalized on an existing intervention to PLHIV in Uganda and conducted a prospective quasi-experimental study evaluating the impact of a monthly household food basket, provided to food insecure antiretroviral therapy-naive PLHIVs for 12 months. The outcomes of interest measured at baseline and follow-up were nutritional status [body mass index; mid-upper arm circumference and hemoglobin (Hb) concentrations], disease severity (CD4 count), and 2 measures of food security: diet quality (Individual Dietary Diversity Score) and food access (Household Food Insecurity Access Scale). We used difference-in-difference propensity score matching to examine the impact of food assistance. RESULTS: Over 12 months, food assistance significantly increased body mass index by 0.6 kg/m (P < 0.01) and mid-upper arm circumference by 6.7 mm (P < 0.05). We found no impact on CD4 count, Hb concentrations, or Individual Dietary Diversity Score. Restricting the analysis to individuals with CD4 counts of greater than 350 cells per microliter, there were significant impacts on Hb concentrations (1.0 g/dL; P < 0.05). At the household level, food assistance increased the Household Food Insecurity Access Scale, by 2.1 points (P < 0.01). CONCLUSIONS: This study demonstrates the potential for food assistance programming to be part of the standard of care for PLHIV in areas of widespread food insecurity.
