RESUMEN

OBJECTIVES: Health technology assessment (HTA) guidance often recommends a 3% real annual discount rate, the appropriateness of which has received limited attention. This article seeks to identify an appropriate rate for high-income countries because it can influence projected cost-effectiveness and hence resource allocation recommendations. METHODS: The author conducted 2 Pubmed.gov searches. The first sought articles on the theory for selecting a rate. The second sought HTA guidance documents. RESULTS: The first search yielded 21 articles describing 2 approaches. The "Ramsey Equation" sums contributions by 4 factors: pure time preference, catastrophic risk, wealth effect, and macroeconomic risk. The first 3 factors increase the discount rate because they indicate future impacts are less important, whereas the last, suggesting greater future need, decreases the discount rate. A fifth factor-project-specific risk-increases the discount rate but does not appear in the Ramsey Equation. Market interest rates represent a second approach for identifying a discount rate because they represent competing investment returns and hence opportunity costs. The second search identified HTA guidelines for 32 high-income countries. Twenty-two provide no explicit rationale for their recommended rates, 8 appeal to market interest rates, 3 to consistency, and 3 to Ramsey Equation factors. CONCLUSIONS: Declining consumption growth and real interest rates imply HTA guidance should reduce recommended discount rates to 1.5 to 2+%. This change will improve projected cost-effectiveness for therapies with long-term benefits and increase the impact of accounting for long-term drug price dynamics, including reduced prices attending loss of market exclusivity.

RESUMEN

BACKGROUND: Research on racial and ethnic disparities in costs of care during the course of dementia is sparse. We analyzed Medicare expenditures for beneficiaries with dementia to identify when during the course of care costs are the highest and whether they differ by race and ethnicity. METHODS: We analyzed data from the 2000-2016 Health and Retirement Study (HRS) linked with corresponding Medicare claims to estimate total Medicare expenditures for four phases: (1) the year before a dementia diagnosis, (2) the first year following a dementia diagnosis, (3) ongoing care for dementia after the first year, and (4) the last year of life. We estimated each patient's phase-specific and disease course Medicare expenditures by using a race-specific survival model and monthly expenditures adjusted for patient characteristics. We investigated healthcare utilization by service type across races/ethnicities and phases of care. RESULTS: Adjusted mean total Medicare expenditures for non-Hispanic (NH) Black ($165,730) and Hispanic beneficiaries with dementia ($160,442) exceeded corresponding expenditures for NH Whites ($136,326). In the year preceding and immediately following initial dementia diagnosis, mean Medicare expenditures for NH Blacks ($26,337 and $20,429) exceeded expenditures for Hispanics and NH Whites ($21,399-23,176 and 17,182-18,244). The last year of life was responsible for the greatest cost contribution: $51,294 (NH Blacks), $47,469 (Hispanics), and $39,499 (NH Whites). These differences were driven by greater use of high-cost services (e.g., emergency department, inpatient and intensive care), especially during the last year of life. CONCLUSIONS: NH Black and Hispanic beneficiaries with dementia had higher disease course Medicare expenditures than NH Whites. Expenditures were highest for NH Black beneficiaries in every phase of care. Further research should address mechanisms of such disparities and identify methods to improve communication, shared decision-making, and access to appropriate services for all populations.

RESUMEN

BACKGROUND: Older adults with dementia including Alzheimer's disease may have difficulty communicating their treatment preferences and thus may receive intensive end-of-life (EOL) care that confers limited benefits. OBJECTIVE: This study compared the use of life-sustaining interventions during the last 90 days of life among Medicare beneficiaries with and without dementia. METHODS: This cohort study utilized population-based national survey data from the 2000-2016 Health and Retirement Study linked with Medicare and Medicaid claims. Our sample included Medicare fee-for-service beneficiaries aged 65 years or older deceased between 2000 and 2016. The main outcome was receipt of any life-sustaining interventions during the last 90 days of life, including mechanical ventilation, tracheostomy, tube feeding, and cardiopulmonary resuscitation. We used logistic regression, stratified by nursing home use, to examine dementia status (no dementia, non-advanced dementia, advanced dementia) and patient characteristics associated with receiving those interventions. RESULTS: Community dwellers with dementia were more likely than those without dementia to receive life-sustaining treatments in their last 90 days of life (advanced dementia: OR = 1.83 [1.42-2.35]; non-advanced dementia: OR = 1.16 [1.01-1.32]). Advance care planning was associated with lower odds of receiving life-sustaining treatments in the community (OR = 0.84 [0.74-0.96]) and in nursing homes (OR = 0.68 [0.53-0.86]). More beneficiaries with advanced dementia received interventions discordant with their EOL treatment preferences. CONCLUSIONS: Community dwellers with advanced dementia were more likely to receive life-sustaining treatments at the end of life and such treatments may be discordant with their EOL wishes. Enhancing advance care planning and patient-physician communication may improve EOL care quality for persons with dementia.

RESUMEN

OBJECTIVES: Health technology assessment (HTA) organizations vary in terms of how they conduct assessments. We assess whether and to what extent HTA bodies have adopted societal and novel elements of value in their economic evaluations. METHODS: After categorizing "societal" and "novel" elements of value, we reviewed fifty-three HTA guidelines. We collected data on whether each guideline mentioned each societal or novel element of value, and if so, whether the guideline recommended the element's inclusion in the base case, sensitivity analysis, or qualitative discussion in the HTA. RESULTS: The HTA guidelines mention on average 5.9 of the twenty-one societal and novel value elements we identified (range 0-16), including 2.3 of the ten societal elements and 3.3 of the eleven novel value elements. Only four value elements (productivity, family spillover, equity, and transportation) appear in over half of the HTA guidelines, whereas thirteen value elements are mentioned in fewer than one-sixth of the guidelines, and two elements receive no mention. Most guidelines do not recommend value element inclusion in the base case, sensitivity analysis, or qualitative discussion in the HTA. CONCLUSIONS: Ideally, more HTA organizations will adopt guidelines for measuring societal and novel value elements, including analytic considerations. Importantly, simply recommending in guidelines that HTA bodies consider novel elements may not lead to their incorporation into assessments or ultimate decision making.

RESUMEN

BACKGROUND: Patient selection for palliative surgery is complex, and appropriate outcomes measures are incompletely defined. We explored the usefulness of a specific outcomes measure "was it worth it" in patients after palliative-intent operations for advanced malignancy. STUDY DESIGN: A retrospective review of a comprehensive longitudinal palliative surgery database was performed at an academic tertiary care center. All patients who underwent palliative-intent operation for advanced cancer from 2003 to 2022 were included. Patient satisfaction ("was it worth it") was reported within 30 days of operation after palliative-intent surgery. RESULTS: A total of 180 patients were identified, and 81.7% self-reported that their palliative surgery was "worth it." Patients who reported that their surgery was "not worth it" were significantly older and were more likely to have recurrent symptoms and to need reoperation. There was no significant difference in overall, recurrence-free, and reoperation-free survival for patients when comparing "worth it" with "not worth it." Initial symptom improvement was not significantly different between groups. Age older than 65 years (hazard ratio 0.25, 95% CI 0.07 to 0.80, p = 0.03), family engagement (hazard ratio 6.71, 95% CI 1.49 to 31.8, p = 0.01), and need for reoperation (hazard ratio 0.042, 95% CI 0.01 to 0.16, p < 0.0001) were all independently associated with patients reporting that their operation was "worth it." CONCLUSIONS: Here we demonstrate that simply asking a patient "was it worth it" after a palliative-intent operation identifies a distinct cohort of patients that traditional outcomes measures fail to distinguish. Family engagement and durability of an intervention are critical factors in determining patient satisfaction after palliative intervention. These data highlight the need for highly individualized care with special attention paid to patients self-reporting that their operation was "not worth it."

RESUMEN

Techniques for studying the clearance of bacterial infections are critical for advances in understanding disease states, immune cell effector functions, and novel antimicrobial therapeutics. Intracellular killing of Staphylococcus aureus by neutrophils can be monitored using a S. aureus strain stably expressing GFP, a fluorophore that is quenched when exposed to the reactive oxygen species (ROS) present in the phagolysosome. Here, we expand upon this method by developing a bi-fluorescent S. aureus killing assay for use in vivo. Conjugating S. aureus with a stable secondary fluorescent marker enables the separation of infected cell samples into three populations: cells that have not engaged in phagocytosis, cells that have engulfed and killed S. aureus, and cells that have viable internalized S. aureus. We identified ATTO647N-NHS Ester as a favorable dye conjugate for generating bi-fluorescent S. aureus due to its stability over time and invariant signal within the neutrophil phagolysosome. To resolve the in vivo utility of ATTO647N/GFP bi-fluorescent S. aureus, we evaluated neutrophil function in a murine model of chronic granulomatous disease (CGD) known to have impaired clearance of S. aureus infection. Analysis of bronchoalveolar lavage (BAL) from animals subjected to pulmonary infection with bi-fluorescent S. aureus demonstrated differences in neutrophil antimicrobial function consistent with the established phenotype of CGD.

RESUMEN

BACKGROUND: We examined racial and ethnic differences in medication use for a representative US population of patients with Alzheimer's disease and related dementias (ADRD). METHODS: We examined cholinesterase inhibitors and memantine initiation, non-adherence, and discontinuation by race and ethnicity, using data from the 2000-2016 Health and Retirement Study linked with Medicare and Medicaid claims. RESULTS: Among newly diagnosed ADRD patients (n = 1299), 26% filled an ADRD prescription ≤90 days and 36% ≤365 days after diagnosis. Among individuals initiating ADRD-targeted treatment (n = 1343), 44% were non-adherent and 24% discontinued the medication during the year after treatment initiation. Non-Hispanic Blacks were more likely than Whites to not adhere to ADRD medication therapy (odds ratio: 1.50 [95% confidence interval: 1.07-2.09]). DISCUSSION: Initiation of ADRD-targeted medications did not vary by ethnoracial group, but non-Hispanic Blacks had lower adherence than Whites. ADRD medication non-adherence and discontinuation were substantial and may relate to cost and access to care. HIGHLIGHTS: Initiation of anti-dementia medications among newly diagnosed Alzheimer's disease and related dementias (ADRD) patients was low in all ethnoracial groups. ADRD medication non-adherence and discontinuation were substantial and may relate to cost and access to care. Compared to Whites, Blacks and Hispanics had lower use, poorer treatment adherence, and more frequent discontinuation of ADRD medication, but when controlling for disease severity and socioeconomic factors, racial disparities diminish. Our findings demonstrate the importance of adjusting for socioeconomic characteristics and disease severity when studying medication use and adherence in ADRD patients.

RESUMEN

OBJECTIVES: Guidance on the conduct of health technology assessments rarely recommends accounting for anticipated future price declines that can follow loss of marketing exclusivity. This article explores when it is appropriate to account for generic pricing and whether it can influence cost-effectiveness estimates. METHODS: This article presents 4 case studies. Case study 1 considers a hypothetical drug used by a first patient cohort at branded prices and by subsequent, "downstream" cohorts at generic prices. Case study 2 explores whether statin assessments should account for generic prices for downstream cohorts that gain access after the initial cohort. Case study 3 uses a simplified spreadsheet model to assess the impact of accounting for generic pricing for inclisiran, used when statins insufficiently reduce cholesterol. Case study 4 amends this model for a hypothetical, advanced, follow-on treatment displacing inclisiran. RESULTS: Assessments should include generic pricing even if the first cohort using a drug pays branded prices and only downstream cohorts pay generic prices (case study 1). Because eventual generic pricing for statins did not depend on decisions for downstream cohorts, assessing reimbursement for those cohorts could safely omit generic pricing (case study 2). For inclisiran (case study 3), including generic pricing notably improved estimated cost-effectiveness. Displacing inclisiran with an advanced therapy (case study 4) modestly affected estimated cost-effectiveness. CONCLUSIONS: Although this analysis relies on simplified and hypothetical models, it demonstrates that accounting for generic pricing might substantially reduce estimated cost-effectiveness ratios. Doing so when warranted is crucial to improving health technology assessment validity.

RESUMEN

Importance: The pool of studies examining ethnic and racial differences in hospice use and end-of-life hospitalizations among patients with dementia is limited and results are conflicting, making it difficult to assess health care needs of underresourced racial and ethnic groups. Objective: To explore differences in end-of-life utilization of hospice and hospital services among patients with dementia by race and ethnicity. Design, Setting, and Participants: This cohort study used national survey data from the Health and Retirement Study linked with Medicare and Medicaid claims that reflected a range of socioeconomic, health, and psychosocial characteristics. Eligible participants were Medicare fee-for-service beneficiaries aged 65 years or older diagnosed with dementia who died between 2000 and 2016. Analyses were performed from June to December 2021. Exposures: Race and ethnicity. Main Outcomes and Measures: We examined the frequency and costs of hospice care, emergency department (ED) visits, and hospitalizations during the last 180 days of life among Medicare decedents with dementia. We analyzed the proportion of dementia decedents with advance care planning and their end-of-life care preferences. Results: The cohort sample included 5058 beneficiaries with dementia (mean [SD] age, 85.5 [8.0] years; 3038 women [60.1%]; 809 [16.0%] non-Hispanic Black, 357 [7.1%] Hispanic, and 3892 non-Hispanic White respondents [76.9%]). In adjusted analysis, non-Hispanic Black decedents (odds ratio [OR], 0.65; 95% CI, 0.55-0.78), nursing home residents (OR, 0.81; 95% CI, 0.71-0.93), and survey respondents represented by a proxy (OR, 0.84; 95% CI, 0.71-0.99) were less likely to use hospice, whereas older decedents (age 75-84 vs 65-74 years: OR, 1.39; 95% CI, 1.12-1.72; age ≥85 vs 65-74 years: OR, 1.39; 95% CI, 1.13-1.71), women (OR, 1.19; 95% CI, 1.05-1.35), and decedents with higher education (high school vs less than high school: OR, 1.17; 95% CI, 1.01-1.36; more than high school vs less than high school: OR, 1.32; 95% CI, 1.13-1.54), more severe cognitive impairment (OR, 1.51; 95% CI, 1.02-2.23), and more instrumental activities of daily living limitations (OR, 1.07; 95% CI, 1.01-1.12) were associated with higher hospice enrollment. A higher proportion of Black and Hispanic decedents with dementia used ED (645 of 809 [79.7%] and 274 of 357 [76.8%] vs 2753 of 3892 [70.7%]; P < .001) and inpatient services (625 of 809 [77.3%] and 275 of 357 [77.0%] vs 2630 of 3892 [67.5%]; P < .001) and incurred roughly 60% higher inpatient expenditures at the end of life compared with White decedents (estimated mean: Black, $23 279; 95% CI, $20 690-$25 868; Hispanic, $23 471; 95% CI, $19 532-$27 410 vs White, $14 609; 95% CI, $13 800-$15 418). A higher proportion of Black and Hispanic than White beneficiaries with dementia who were enrolled in hospice were subsequently admitted to the ED (56 of 309 [18.1%] and 22 of 153 [14.4%] vs 191 of 1967 [9.7%]; P < .001) or hospital (48 of 309 [15.5%] and 17 of 153 [11.1%] vs 119 of 1967 [6.0%]; P < .001) before death. The proportion of dementia beneficiaries completing advance care planning was lower among Black (146 of 704 [20.7%]) and Hispanic (66 of 308 [21.4%]) beneficiaries compared with White beneficiaries (1871 of 3274 [57.1%]). A higher proportion of Black and Hispanic decedents with dementia had written instructions choosing all care possible to prolong life (30 of 144 [20.8%] and 12 of 65 [18.4%] vs 72 of 1852 [3.9%]), whereas a higher proportion of White decedents preferred to limit care in certain situations (1708 of 1840 [92.8%] vs 114 of 141 [80.9%] and 51 of 64 [79.7%]), withhold treatments (1448 of 1799 [80.5%] vs 87 of 140 [62.1%] and 41 of 62 [66.1%]), and forgo extensive life-prolonging measures (1712 of 1838 [93.1%] vs 120 of 138 [87.0%] and 54 of 65 [83.1%]). Conclusions and Relevance: The results of this cohort study highlight unique end-of-life care utilization and treatment preferences across racial and ethnic groups among patients with dementia. Medicare should consider alternative payment models to promote culturally competent end-of-life care and reduce low-value interventions and costs among the population with dementia.

RESUMEN

BACKGROUND: An increasing proportion of novel drug approvals use accelerated pathways, with notable growth in the US Food and Drug Administration-designated breakthrough pathway in recent years. Breakthrough therapy (BT) designation suggests that these therapies offer substantial potential to improve health outcomes but their value for money is not fully understood, as BTs typically cost more than non-BTs (NBTs). OBJECTIVE: To assess the economic value of BTs and factors associated with their reported value. METHODS: Using the Tufts Medical Center Cost-Effectiveness (CE) Analysis Registry, we (1) summarized the CE of BTs, as measured by cost per quality-adjusted-life-year (QALY); (2) compared the CE of BTs and NBTs in the United States; and (3) identified factors associated with BT CE using general estimating equation models across US willingness-to-pay (WTP) benchmarks ($50K-$150K/QALY). RESULTS: Between 2013 and 2018, the US Food and Drug Administration approved 279 drugs, designating 83 (32%) as BTs. Incremental costs and health gains (QALYs) were higher for BTs relative to NBTs ($29,000 vs $20,000 and 0.7 vs 0.2 QALYs, respectively), and BTs had more favorable CE ratios compared with NBTs (median values $38,000/QALY vs $50,000/QALY, respectively). For BTs, hepatitis C treatments had the most favorable CE ratios, which may be driven by the curative nature of some hepatitis C therapies. Furthermore, BT CE ratios for new molecular entities (NMEs) were about 40% lower than ratios for non-NME BTs on average, which may signal more value for money when the BT has a new active molecule. Regression analysis to identify trends driving CE found that BT drugs compared with active comparators (instead of best supportive care) were less likely to be cost-effective at standard US WTP thresholds (odds ratio [OR] = 0.1-0.6) and that BTs in the neoplasm space also trended less likely to be cost-effective (OR = 0.12-0.43). CE ratios reported by studies with industry funding were also more likely to be cost-effective than ratios from studies with other funding sources (OR = 4.3-4.5), though this finding was not significant at WTP thresholds over $50,000/QALY gained. CONCLUSIONS: Evidence from published, peer-reviewed CE studies suggests that BTs may confer greater health benefits than NBTs in terms of overall QALYs. Our analysis supports that the US Food and Drug Administration BT designation may be associated with increased value for money for these BTs. However, factors such as the disease area, NME status, and comparator (active vs standard of care) will also influence whether these therapies are cost-effective.

RESUMEN

PURPOSE: This study aimed to estimate the cost-effectiveness of exome sequencing (ES) and genome sequencing (GS) for children. METHODS: We modeled costs, diagnoses, and quality-adjusted life years (QALYs) for diagnostic strategies for critically ill infants (aged <1 year) and children (aged <18 years) with suspected genetic conditions: (1) standard of care (SOC) testing, (2) ES, (3) GS, (4) SOC followed by ES, (5) SOC followed by GS, (6) ES followed by GS, and (7) SOC followed by ES followed by GS. We calculated the 10-year incremental cost per additional diagnosis, and lifetime incremental cost per QALY gained, from a health care perspective. RESULTS: First-line GS costs $15,048 per diagnosis vs SOC for infants and $27,349 per diagnosis for children. If GS is unavailable, ES represents the next most efficient option compared with SOC ($15,543 per diagnosis for infants and $28,822 per diagnosis for children). Other strategies provided the same or fewer diagnoses at a higher incremental cost per diagnosis. Lifetime results depend on the patient's assumed long-term prognosis after diagnosis. For infants, GS ranged from cost-saving (vs all alternatives) to $18,877 per QALY (vs SOC). For children, GS (vs SOC) ranged from $119,705 to $490,047 per QALY. CONCLUSION: First-line GS may be the most cost-effective strategy for diagnosing infants with suspected genetic conditions. For all children, GS may be cost-effective under certain assumptions. ES is nearly as efficient as GS and hence is a viable option when GS is unavailable.

RESUMEN

OBJECTIVES: This study aimed to explore the impact of including broader value elements in cost-effectiveness analyses by presenting 2 case studies, one on human papillomavirus (HPV) infection and one on early-stage Hodgkin's lymphoma (ESHL). METHODS: We identified broader value elements (eg, patient and caregiver time, spillover health effects, productivity) from the Second Panel's Impact Inventory and the ISPOR Special Task Force's value flower. We then evaluated the cost-effectiveness of HPV vaccination versus no vaccination (case 1) and combined modality therapy (CMT) versus chemotherapy alone for treatment of adult ESHL (case 2) using published simulation models. For each case study, we compared incremental cost-effectiveness ratios considering health sector impacts only (the "base-case" scenario) with incremental cost-effectiveness ratios incorporating broader value elements. RESULTS: For vaccination of US girls against HPV before sexual debut versus no vaccination, the base-case result was $38 334 per disability-adjusted life-year averted. Including each broader value element made cost-effectiveness progressively more favorable, with HPV vaccination becoming cost-saving (ie, reducing costs and averting more disability-adjusted life-years) when the analysis incorporated productivity costs. For CMT versus chemotherapy alone in patients with ESHL, the base-case result indicated that CMT was cost-saving. Including all elements made this treatment's net monetary benefits (the sum of its averted resource costs and the net value of its health impacts) less favorable, even as the contribution from CMT's near-term health benefits grew. CONCLUSIONS: Including broader value elements can substantially influence cost-effectiveness ratios, although the direction and the magnitude of their impact can differ across interventions and disease context.

RESUMEN

The development and use of murine myeloid progenitor cell lines that are conditionally immortalized through expression of HoxB8 has provided a valuable tool for studies of neutrophil biology. Recent work has extended the utility of HoxB8-conditional progenitors to the in vivo setting via their transplantation into irradiated mice. Here, we describe the isolation of HoxB8-conditional progenitor cell lines that are unique in their ability to engraft in the naïve host in the absence of conditioning of the hematopoietic niche. Our results indicate that HoxB8-conditional progenitors engraft in a ß1 integrin-dependent manner and transiently generate donor-derived mature neutrophils. Furthermore, we show that neutrophils derived in vivo from transplanted HoxB8-conditional progenitors are mobilized to the periphery and recruited to sites of inflammation in a manner that depends on the C-X-C chemokine receptor 2 and ß2 integrins, the same mechanisms that have been described for recruitment of endogenous primary neutrophils. Together, our studies advance the understanding of HoxB8-conditional neutrophil progenitors and describe an innovative tool that, by virtue of its ability to engraft in the naïve host, will facilitate mechanistic in vivo experimentation on neutrophils.

RESUMEN

OBJECTIVES: We investigated how health technology assessment (HTA) organizations around the world have handled drug genericization (an allowance for future generic drug entry and subsequent drug price declines) in their guidelines for cost-effectiveness analyses (CEAs). We also analyzed a large sample of published CEAs to examine prevailing practices in the field. METHODS: We reviewed 43 HTA guidelines to determine whether and how they addressed drug genericization in their CEAs. We also selected a sample of 270 US-based CEAs from the Tufts Medical Center's CEA Registry, restricting the sample to studies on pharmaceuticals published from 1991 to 2019 and to analyses taking a lifetime time horizon. We determined whether each CEA examined genericization (and if so, whether in base case or sensitivity analyses), and how inclusion of genericization influenced the estimated incremental cost-effectiveness ratios. RESULTS: Fourteen (33%) of the 43 HTA guidelines mention genericization for CEAs and 4 (9%) recommend that base case analyses include assumptions about future drug price changes due to genericization. Most published CEAs (95%) do not include assumptions about future generic prices for intervention drugs. Only 2% include such assumptions about comparator drugs. Most studies (72%) conduct sensitivity analyses on drug prices unrelated to genericization. CONCLUSIONS: The omission of assumptions about genericization means that CEAs may misrepresent the long run opportunity costs for drugs. The field needs clearer guidance for when CEAs should account for genericization, and for the inclusion of other price dynamics that might influence a drug's cost-effectiveness.

RESUMEN

OBJECTIVE: Medical devices can offer important therapeutic advances but, as for any medical interventions, there are questions about their costs and benefits. We examined health benefits and costs for pre-market approved (PMA) devices approved by the US Food and Drug Administration (FDA) (1999-2015), grouping them by generic category (e.g., drug-eluting stents) and indication. METHODS: We searched PubMed for incremental health gain estimates [measured in quality-adjusted life-years (QALYs)] and incremental costs for each device category compared to previously available treatments. We calculated incremental cost-effectiveness ratios by dividing the average incremental costs by the average incremental QALY gains. In sensitivity analysis, we repeated the analysis when excluding industry-funded studies. RESULTS: We identified at least one relevant cost-utility or comparative-effectiveness study for 88 devices (15.9% of non-cosmetic devices approved from 1999 to 2015), and at least one device across 53 (26.2%) generic categories. The median (mean) incremental cost across generic device categories was $1701 ($13,320). The median (mean) incremental health gain across generic device categories was 0.13 (0.46) QALYs. We found that cost-effectiveness ratios for 36 of 53 (68%) and 43 of 53 (81%) device categories fell below (were more favorable than) $50,000 and $150,000 per QALY, respectively. Results were roughly similar when we excluded industry-funded studies. CONCLUSIONS: We found that roughly one-quarter of the major PMA medical device categories have published cost-effectiveness evidence accessible through a large, publicly available database. Available evidence suggests that devices generally offer good value, as judged relative to established cost-effectiveness benchmarks.

RESUMEN

No one person has the right or ability to make decisions about to whom or according to which criteria palliative surgery should be offered. Instead, patient and surgeon together must consider symptom severity, goals of care, and the value palliative surgery could add to the patient's health experience or quality of life.
