[PMID: 35138547 PMCID: PMC9708961 DOI: 10.1007/s11606-021-07316-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 12/07/2021] [Indexed: 01/04/2023]
Abstract
BACKGROUND Drugs and high-risk medical devices are increasingly likely to receive Food and Drug Administration (FDA) approval through expedited pathways, which has implications for informed treatment consent (i.e., consent in clinical practice). OBJECTIVE To obtain expert opinion about the clinical and ethical implications of the increasing availability of new drugs and devices approved through expedited development and regulatory review pathways. DESIGN Qualitative study using individual semi-structured videoconference interviews. PARTICIPANTS National leaders in medicine, ethics, and law (n=12) with expertise in medical product regulation, payor policymaking, bioethics, physician practice, patient advocacy, public health expertise/advocacy, clinical trials, the pharmaceutical and device industry, institutional review board oversight, and real-world evidence. MAIN MEASURES Principal themes in 3 domains: expedited regulatory pathways, physician and patient understanding of and reliance on FDA approval, and informed treatment consent. KEY RESULTS Respondents pointed out that more common use of expedited pathways translates to increased reliance on surrogate measures, some with uncertain clinical significance. While expedited development and review can have advantages, participants expressed worry that physicians were unaware when medical products were expedited and did not communicate about uncertainties in knowledge about new drug or device approvals effectively with patients. Many participants felt that informed treatment consent discussions about new drugs or devices should include some explanations of expedited pathways and use of surrogate measures. CONCLUSIONS Experts identified advantages of expediting development and of FDA flexibility in applying its standards to new drugs and medical devices, but highlighted concerns that patients may not be adequately informed about the risks of shorter review times or about uncertainties in the evidence that result. There is a need to identify approaches to ensure effective clinical use of drugs and devices when approved through expedited pathways.

Abstract
ObjectivesGenerating and using real-world evidence (RWE) is a pragmatic solution for evaluating health technologies. RWE is recognized by regulators, health technology assessors, clinicians, and manufacturers as a valid source of information to support their decision-making. Well-designed registries can provide RWE and become more powerful when linked with electronic health records and administrative databases in coordinated registry networks (CRNs). Our objective was to create a framework of maturity of CRNs and registries, so guiding their development and the prioritization of funding.Design, setting, and participantsWe invited 52 stakeholders from diverse backgrounds including patient advocacy groups, academic, clinical, industry and regulatory experts to participate on a Delphi survey. Of those invited, 42 participated in the survey to provide feedback on the maturity framework for CRNs and registries. An expert panel reviewed the responses to refine the framework until the target consensus of 80% was reached. Two rounds of the Delphi were distributed via Qualtrics online platform from July to August 2020 and from October to November 2020.Main outcome measuresConsensus on the maturity framework for CRNs and registries consisted of seven domains (unique device identification, efficient data collection, data quality, product life cycle approach, governance and sustainability, quality improvement, and patient-reported outcomes), each presented with five levels of maturity.ResultsOf 52 invited experts, 41 (79.9%) responded to round 1; all 41 responded to round 2; and consensus was reached for most domains. The expert panel resolved the disagreements and final consensus estimates ranged from 80.5% to 92.7% for seven domains.ConclusionsWe have developed a robust framework to assess the maturity of any CRN (or registry) to provide reliable RWE. This framework will promote harmonization of approaches to RWE generation across different disciplines and health systems. The domains and their levels may evolve over time as new solutions become available.

Abstract
OBJECTIVE To emulate the GRADE (Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness Study) trial using real world data before its publication. GRADE directly compared second line glucose lowering drugs for their ability to lower glycated hemoglobin A1c (HbA1c). DESIGN Observational study. SETTING OptumLabs® Data Warehouse (OLDW), a nationwide claims database in the US, 25 January 2010 to 30 June 2019. PARTICIPANTS Adults with type 2 diabetes and HbA1c 6.8-8.5% while using metformin monotherapy, identified according to the GRADE trial specifications, who also used glimepiride, liraglutide, sitagliptin, or insulin glargine. MAIN OUTCOME MEASURES The primary outcome was time to HbA1c ≥7.0%. Secondary outcomes were time to HbA1c >7.5%, incident microvascular complications, incident macrovascular complications, adverse events, all cause hospital admissions, and all cause mortality. Propensity scores were estimated using the gradient boosting machine method, and inverse propensity score weighting was used to emulate randomization of the treatment groups, which were then compared using Cox proportional hazards regression. RESULTS 8252 people were identified (19.7% of adults starting the study drugs in OLDW) who met eligibility criteria for the GRADE trial (glimepiride arm=4318, liraglutide arm=690, sitagliptin arm=2993, glargine arm=251). The glargine arm was excluded from analyses owing to small sample size. Median times to HbA1c ≥7.0% were 442 days (95% confidence interval 394 to 480 days) for glimepiride, 764 (741 to not calculable) days for liraglutide, and 427 (380 to 483) days for sitagliptin. Liraglutide was associated with lower risk of reaching HbA1c ≥7.0% compared with glimepiride (hazard ratio 0.57, 95% confidence interval 0.43 to 0.75) and sitagliptin (0.55, 0.41 to 0.73). Results were consistent for the secondary outcome of time to HbA1c >7.5%. No significant differences were observed among treatment groups for the remaining secondary outcomes. CONCLUSIONS In this emulation of the GRADE trial, liraglutide was statistically significantly more effective at maintaining glycemic control than glimepiride or sitagliptin when added to metformin monotherapy. Generating timely evidence on medical treatments using real world data as a complement to prospective trials is of value.

Abstract
BACKGROUND There is an increasing burden of cardiovascular disease, including coronary artery disease (CAD) and heart failure (HF), among women Veterans. Clinical practice guidelines recommend multiple pharmacotherapies that can reduce risk of mortality and adverse cardiovascular outcomes. OBJECTIVE To determine if there are disparities in the use of guideline-directed medical therapy by gender among Veterans with incident CAD and HF. DESIGN Retrospective. PARTICIPANTS Veterans (934,504; 87.8% men and 129,469; 12.2% women) returning from Operations Enduring Freedom, Iraqi Freedom, and New Dawn. MAIN MEASURES Differences by gender in the prescription of Class 1, Level of Evidence A guideline-directed medical therapy among patients who developed incident CAD and HF at 30 days, 90 days, and 12 months after diagnosis. For CAD, medications included statins and antiplatelet therapy. For HF, medications included beta-blockers and renin-angiotensin-aldosterone system inhibitors. KEY RESULTS Overall, women developed CAD and HF at a younger average age than men (mean 45.8 vs. 47.7 years, p<0.001; and 43.7 vs. 45.4 years, p<0.02, respectively). In the 12 months following a diagnosis of incident CAD, the odds of a woman receiving a prescription for at least one CAD drug was 0.85 (95% confidence interval [CI], 0.68-1.08) compared to men. In the 12 months following a diagnosis of incident HF, the odds of a woman receiving at least one HF medication was 0.54 (95% CI, 0.37-0.79) compared to men. CONCLUSIONS Despite guideline recommendations, young women Veterans have approximately half the odds of being prescribed guideline-directed medical therapy within 1-year after a diagnosis of HF. These results highlight the need to develop targeted strategies to minimize gender disparities in CVD care to prevent adverse outcomes in this young and growing population.

Abstract
BACKGROUND Professional societies strongly recommend remote monitoring (RM) of all cardiac implantable electronic devices, and higher RM adherence is associated with improved patient outcomes. However, adherence with RM is suboptimal. OBJECTIVE The purpose of this study was to better understand factors associated with RM adherence. METHODS We linked RM data from the Veterans Affairs National Cardiac Device Surveillance Program to clinical data for patients monitored between October 25, 2018, and October 24, 2020. RM adherence was defined as the percentage of days covered by an RM transmission during the study period. Patients were classified into 3 categories: complete (100% of days covered by an RM transmission), intermediate (above median in patients with <100% adherence), and low (below median in patients with <100% adherence) adherence. We used multivariable logistic regression to examine patient, device, and facility characteristics associated with adherence. RESULTS In 52,574 patients, average RM adherence was 71.9%. Only 30.9% (16,224) of patients had complete RM adherence. Black or African American patients had a lower odds of complete RM adherence than white patients (odds ratio 0.88; 95% confidence interval 0.82-0.94), and Hispanic or Latino patients had a lower odds of complete RM adherence (odds ratio 0.79; 95% confidence interval 0.70-0.89) than non-Hispanic or Latino patients. Dementia, depression, and posttraumatic stress disorder were associated with a lower odds of RM adherence. CONCLUSION There are significant disparities in RM adherence by race, ethnicity, and neuropsychiatric comorbidities. These findings can inform strategies to improve health equity and ensure that all patients with cardiac implantable electronic devices receive the evidence-based clinical benefits of RM.

Abstract
BACKGROUND Percutaneous ventricular assist devices (PVADs) have been replacing intra-aortic balloon pumps for hemodynamic support during percutaneous coronary intervention (PCI), even though data supporting a benefit for hard clinical end points remain limited. We evaluated diffusion of PVADs across US markets and examined the association of market utilization of PVAD with mortality and cost. METHODS Using the 2013 to 2019 Medicare data, we identified all patients aged ≥65 years who underwent PCI with either a PVAD or intra-aortic balloon pump. We used hospital referral region to define regional health care markets and categorized them in quartiles based on the proportional use of PVADs during PCI. Multilevel models were constructed to determine the association of patient, hospital, and market factors with utilization of PVADs and the association of PVAD utilization with 30-day mortality and cost. RESULTS A total of 79 176 patients underwent PCI with either intra-aortic balloon pump (47 514 [60.0%]) or PVAD (31 662 [40.0%]). The proportion of PCI procedures with PVAD increased over time (17% in 2013 to 57% in 2019; P for trend, <0.001), such that PVADs overtook intra-aortic balloon pump for hemodynamic support during PCI in 2018. There was a large variation in PVAD utilization across markets (range, 0%-85%), which remained unchanged after adjustment of patient characteristics (median odds ratio, 2.05 [95% CI, 1.91-2.17]). The presence of acute myocardial infarction, cardiogenic shock, and emergent status was associated with a 45% to 50% lower odds of PVAD use suggesting that PVADs were less likely to be used in the sickest patients. Greater utilization of PVAD at the market level was not associated with lower risk mortality but was associated with higher cost. CONCLUSIONS Although utilization of PVADs for PCI continues to increase, there is large variation in PVAD utilization across markets. Greater market utilization of PVADs was not associated with lower mortality but was associated with higher cost.

Abstract
IMPORTANCE The ThermoCool SmartTouch catheter (ablation catheter with contact force and 6-hole irrigation [CF-I6]) is approved by the US Food and Drug Administration (FDA) for paroxysmal atrial fibrillation (AF) ablation and used in routine clinical practice for persistent AF ablation, although clinical outcomes for this indication are unknown. There is a need to understand whether data from routine clinical practice can be used to conduct regulatory-grade evaluations and support label expansions. OBJECTIVE To use health system data to compare the safety and effectiveness of the CF-I6 catheter for persistent AF ablation with the ThermoCool SmartTouch SurroundFlow catheter (ablation catheter with contact force and 56-hole irrigation [CF-I56]), which is approved by the FDA for this indication. DESIGN, SETTING, AND PARTICIPANTS This retrospective, comparative-effectiveness cohort study included patients undergoing catheter ablation for persistent AF at Mercy Health or Mayo Clinic from January 1, 2014, to April 30, 2021, with up to a 1-year follow-up using electronic health record data. EXPOSURES Use of the CF-I6 or CF-I56 catheter. MAIN OUTCOMES AND MEASURES The primary safety outcome was a composite of death, thromboembolic events, and procedural complications within 7 to 90 days. The exploratory effectiveness outcome was a composite of AF-related hospitalization events after a 90-day blanking period. Propensity score weighting was used to balance baseline covariates. Risk differences were estimated between catheter groups and averaged across the 2 health care systems, testing for noninferiority of the CF-I6 vs the CF-I56 catheter with respect to the safety outcome using 2-sided 90% CIs. RESULTS Overall, 1450 patients (1034 [71.3%] male; 1397 [96.3%] White) underwent catheter ablation for persistent AF, including 949 at Mercy Health (186 CF-I6 and 763 CF-I56; mean [SD] age, 64.9 [9.2] years) and 501 at Mayo Clinic (337 CF-I6 and 164 CF-I56; mean [SD] age, 63.7 [9.5] years). A total of 798 (55.0%) had been treated with class I or III antiarrhythmic drugs before ablation. The safety outcome (CF-I6 - CF-I56) was similar at both Mercy Health (1.3%; 90% CI, -2.1% to 4.6%) and Mayo Clinic (-3.8%; 90% CI, -11.4% to 3.7%); the mean difference was noninferior, with a mean of 0.5% (90% CI, -2.6% to 3.5%; P < .001). The effectiveness was similar at 12 months between the 2 catheter groups (mean risk difference, -1.8%; 90% CI, -7.3% to 3.7%). CONCLUSIONS AND RELEVANCE In this cohort study, the CF-I6 catheter met the prespecified noninferiority safety criterion for persistent AF ablation compared with the CF-I56 catheter, and effectiveness was similar. This study demonstrates the ability of electronic health care system data to enable safety and effectiveness evaluations of medical devices.

Abstract
Background Implantable cardioverter-defibrillators (ICDs) reduce the risk of sudden cardiac death among patients with persistently reduced (≤35 %) left ventricular ejection fraction (LVEF) at least 40 days following acute myocardial infarction (AMI). Few prior studies have used LVEF measured after the 40-day waiting period to examine primary prevention ICD placement. Methods We sought to determine factors associated with ICD placement among patients who met LVEF criteria post-MI within a large integrated health care system in the U.S by conducting a retrospective cohort study of Veteran patients hospitalized for AMI from 2004 to 2017 who had documented LVEF ≤35 % from echocardiograms performed between 40 and 455 (90 days +1 year) days post-MI. We used multivariable logistic regression to examine factors associated with ICD placement. Results Of 12,893 patients with LVEF ≤35 % at least 40 days post-MI, 2176 (16.9 %) received an ICD between 91- and 455-days post-MI. Younger age, fewer comorbidities, revascularization with PCI, and greater use of GDMT were associated with increased odds of receiving an ICD. However, half of patients treated with a beta-blocker, ACE inhibitor or angiotensin receptor blocker, and mineralocorticoid receptor antagonist prior to LVEF assessment did not receive an ICD. Eligible Black patients were less likely (odds ratio 0.80, 95 % confidence interval 0.69-0.92) to receive an ICD than White patients. Conclusion Many factors affect ICD placement among Veteran patients with a confirmed LVEF ≤35 % at least 40 days post-MI. Greater understanding of factors influencing ICD placement would help clinicians ensure guideline-concordant care.

Abstract
BACKGROUND Beta-blockers, angiotensin receptor-neprilysin inhibitor (ARNI), mineralocorticoid receptor antagonists, and sodium-glucose cotransporter-2 inhibitors (SGLT2i), known as quadruple therapy, are recommended for patients with heart failure with reduced ejection fraction (HFrEF). OBJECTIVES This study sought to determine Medicare coverage and out-of-pocket (OOP) costs of quadruple therapy and regimens excluding ARNI or SGLT2i. METHODS This study assessed cost sharing, prior authorization, and step therapy in all 4,068 Medicare prescription drug plans in 2020. OOP costs were determined during the standard coverage period and annually based on the Medicare Part D standard benefit, inclusive of deductible, standard coverage, coverage gap, and catastrophic coverage. RESULTS Tier ≥3 cost sharing was required by 99.1% of plans for ARNI and 98.5% for at least 1 SGLT2i. Only ARNI required prior authorization (24.3% of plans), and step therapy was required only for SGLT2is (5.4%) and eplerenone (0.8%). The median 30-day standard coverage OOP cost of quadruple therapy was $94 (IQR: $84-$100), including $47 (IQR: $40-$47) for ARNI and $45 (IQR: $40-$47) for SGLT2i. The median annual OOP cost of quadruple therapy was $2,217 (IQR: $1,956-$2,579) compared with $1,319 (IQR: $1,067-$1,675) when excluding SGLT2i and $1,322 (IQR: $1,025-$1,588) when including SGLT2i and substituting an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker for ARNI. The median 30-day OOP cost of generic regimens was $3 (IQR: $0-$9). CONCLUSIONS Medicare drug plans restrict coverage of quadruple therapy through cost sharing, with OOP costs that are substantially higher than generic regimens. Quadruple therapy may be unaffordable for many Medicare patients with HFrEF unless medication prices and cost sharing are reduced.

Abstract
Prescription drugs and medical devices are increasingly coming to market through expedited US Food and Drug Administration (FDA) pathways that require only limited evidence of safety and efficacy, such as nonrandomized, unblinded trial data in small numbers of patients, or the use of surrogate end points. Reliance on more limited evidence means that there is often greater uncertainty about risks and benefits. Using a modified Delphi process, we sought to identify promising policy approaches that address physician-patient decision-making needs about the use of such drugs and medical devices. We convened 13 national leaders from academia, government, nonprofits, payors, and industry who had expertise in medical product regulation, payor policymaking, bioethics, physician practice, patient advocacy, public health expertise/advocacy, clinical trials, the pharmaceutical and device industry, institutional review board oversight, and real-world evidence. Through multiple rounds of voting and meetings focused on evaluating the feasibility and impact of various interventions, the 13 participants reached the broadest consensus on 4 interventions: strengthening FDA post-approval study requirements to ensure postmarket evidence is generated in a timely manner, better informing patients about the risks and benefits and level of evidence supporting therapies via simplified and patient-centered product information "boxes" modeled on nutrition labels, limiting prices for drugs and medical devices approved based on surrogate end point data until confirmatory clinical evidence is generated, and improving health professional education about FDA regulation to better support clinician use of drugs and devices as well as communication with patients.

Abstract
Background:
Current important regulatory resources and methods to identify cardiac implantable electronic devices (CIED) lead failure include post-approval studies, which may be limited in scope, participant numbers, and by attrition; studies relying on administrative codes, which lack specificity in multi-chamber systems; and voluntary adverse event reporting, which cannot determine incidence or attribution to the lead. We determined whether adjudicated remote monitoring (RM) data can help to address these limitations and augment lead safety evaluation.
Methods:
We evaluated 48,148 patients from the Veterans Affairs National Cardiac Device Surveillance Program (VANCDSP), 4/1/19-4/1/21. We identified RM transmissions signifying incident lead abnormalities (possible lead failure, failure to capture, impedance out of range). We queried VA electronic health record (EHR) and Medicare fee-for-service claims data to determine if patients had administrative codes for lead failure. We verified structural lead failure through manual EHR review. Among patients with EHR-confirmed lead failure, we categorized subsequent clinical actions by cardiac chamber.
Results:
Of 48,148 actively monitored patients with CIEDs, 1174 (2.4%) had incident lead abnormalities detected on RM; 356 (30.3%) with administrative codes for lead failure and 818 (69.7%) without. Of the 356 patients, 220 (62%) had lead failure verified through chart review (positive predictive value [PPV], 62%). Among 276 patients randomly selected from 818 without administrative codes, 58 (26%) had EHR-confirmed lead failure (PPV, 21%). Patients with isolated right atrial or left ventricular lead failure were less likely to have claims and lead replacement procedures than those with right ventricular high-energy lead failure (Table).
Conclusion:
Remote monitoring may strengthen accurate real-world assessment of lead failure, particularly for leads where patients do not undergo replacement.

Abstract
Background:
While the US FDA has cleared wearable device software for the detection of irregular rhythms suggestive of atrial fibrillation, there is little evidence to guide decision-making in response to abnormal rhythm notifications. We evaluated physician practice patterns across specialties at 2 large academic centers.
Methods:
We conducted a case-based survey of attending and resident physicians in primary care, emergency medicine, and cardiology at Yale and UCSF from September to December 2021. Case scenarios were presented where patients reported receiving wearable device alerts for “signs of an irregular rhythm suggestive of atrial fibrillation” in the absence of symptoms. Physicians were asked to select from among prespecified diagnostic testing, referral and treatment options, including none. We used a Chi-square test of independence to compare decisions across specialties.
Results:
We emailed 636 physicians and 95 surveys (14.9%) were completed: 39 primary care, 25 emergency medicine, and 31 cardiology. In response to 192 case scenarios, 99.5% of physicians selected at least one diagnostic test: electrocardiography (96.4%), ambulatory rhythm monitoring (77.1%), transthoracic echocardiography (TTE) (32.8%), stress tests (9.9%), and brain natriuretic peptide (BNP) (8.9%) (Fig A). When asked about referral and treatment options, 18.8% of physicians selected referral to a different specialty and 25.0% selected new medication treatment, including aspirin (18.2%), antiarrhythmics (15.1%), and anticoagulation (9.4%) (Fig B). Emergency physicians were more likely than primary care physicians and cardiologists to refer patients (P=.048) and order a BNP (P=.003). Cardiologists were more likely to perform ambulatory rhythm monitoring (P<.001) and prescribe antiarrhythmics (P=.02).
Conclusion:
There was considerable variation across physician specialties in practice patterns for asymptomatic, device-detected irregular rhythms.

Abstract
Background Personal digital devices may offer insights into patient recovery and an approach for remote monitoring after procedures. Objective To examine associations between activity measured using personal digital devices, patient-reported outcome measures (PROMs), and clinical events among patients after catheter ablation for atrial fibrillation (AF) or bariatric surgery. Methods We aggregated personal digital device, PROM, and electronic health record data in a study conducted at 2 health systems. We used Fitbit devices for step count assessments, KardiaMobile for cardiac rhythm assessments, and PROMs for pain and palpitations over 5 weeks. Results Among 59 patients, 30 underwent AF ablation and 29 bariatric surgery. Thirty-six patients (63%) reported pain. There was no difference in median [interquartile range] daily steps between patients with and those without pain (4419 [3286–7041] vs 3498 [2609–5888]; P = .23). Among AF ablation patients, 21 (70%) reported palpitations. Median daily steps were lower among those with palpitations than among those without (4668 [3021–6116] vs 8040 [6853–10,394]; P = .03). When accounting for within-subject correlation, recordings of AF were associated with a significant mean decrease in median daily steps (–351; 95% confidence interval –524 to –177; P <.01). Patients who received a new antiarrhythmic drug prescription had AF recorded in a median of 5 [5–5] of 5 total weeks, whereas patients who did not receive a new antiarrhythmic recorded AF in a median of 1 [0–3] week (P = .02). Conclusion Personal digital device and PROM data can provide insight into postprocedural recovery outside of usual clinical settings and may inform follow-up and clinical decision-making.

Assessment of Hypothetical Out-of-Pocket Costs of Guideline-Recommended Medications for the Treatment of Older Adults With Multiple Chronic Conditions, 2009 and 2019. JAMA Intern Med 2022; 182:185-195. [PMID: 34982097 PMCID: PMC8728660 DOI: 10.1001/jamainternmed.2021.7457] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 10/14/2021] [Indexed: 01/07/2023]
Abstract
IMPORTANCE Most adults 65 years or older have multiple chronic conditions. Managing these conditions with prescription drugs can be costly, particularly for older adults with limited incomes. OBJECTIVE To estimate hypothetical out-of-pocket costs associated with guideline-recommended outpatient medications for the initial treatment of 8 common chronic diseases among older adults with Medicare prescription drug plans (PDPs). DESIGN, SETTING, AND PARTICIPANTS This retrospective cross-sectional study used 2009 and 2019 Medicare prescription drug plan formulary files to estimate annual out-of-pocket costs among hypothetical patients enrolled in Medicare Advantage or stand-alone Medicare Part D plans. A total of 3599 PDPs in 2009 and 3618 PDPs in 2019 were included after inclusion and exclusion criteria were applied. Costs associated with guideline-recommended medications for 8 of the most common chronic diseases (atrial fibrillation, chronic obstructive pulmonary disease [COPD], heart failure with reduced ejection fraction, hypercholesterolemia, hypertension, osteoarthritis, osteoporosis, and type 2 diabetes), alone and in 2 clusters of commonly comorbid conditions, were examined. MAIN OUTCOMES AND MEASURES Annual out-of-pocket costs for each chronic condition, inflation adjusted to 2019 dollars. RESULTS Among 3599 Medicare PDPs in 2009, 1998 were Medicare Advantage plans and 1601 were stand-alone plans; among 3618 Medicare PDPs in 2019, 2719 were Medicare Advantage plans and 899 were stand-alone plans. For an older adult enrolled in any Medicare PDP in 2019, the median annual out-of-pocket costs for individual conditions varied, from a minimum of $32 (IQR, $6-$48) for guideline-recommended management of osteoporosis (a decrease from $128 [IQR, $102-$183] in 2009) to a maximum of $1579 (IQR, $1524-$2229) for guideline-recommended management of atrial fibrillation (an increase from $91 [IQR, $73-$124] in 2009). For an older adult with a cluster of 5 commonly comorbid conditions (COPD, hypertension, osteoarthritis, osteoporosis, and type 2 diabetes) enrolled in any PDP, the median out-of-pocket cost in 2019 was $1999 (IQR, $1630-$2564), a 12% decrease from $2284 (IQR, $1920-$3107) in 2009. For an older adult with all 8 chronic conditions (atrial fibrillation, COPD, diabetes, hypercholesterolemia, heart failure, hypertension, osteoarthritis, and osteoporosis) enrolled in any PDP, the median out-of-pocket cost in 2019 was $3630 (IQR, $3234-$5197), a 41% increase from $2571 (IQR, $2185-$3719) in 2009. CONCLUSIONS AND RELEVANCE In this cross-sectional study, out-of-pocket costs for guideline-recommended outpatient medications for the initial treatment of 8 common chronic diseases varied by condition. Although costs generally decreased between 2009 and 2019, particularly with regard to conditions for which generic drugs were available, out-of-pocket costs remained high and may have presented a substantial financial burden for Medicare beneficiaries, especially older adults with conditions for which brand-name drugs were guideline recommended.

Abstract
This study aimed to assess long-term resource utilization and outcomes in patients with acute chest pain who underwent coronary computed tomography angiography (CCTA) and stress echocardiography (SE). This was a retrospective, propensity-matched analysis of health insurance claims data for a national sample of privately insured patients over the period January 1, 2011, to December 31, 2014. There were 3,816 patients matched 1:1 who received either CCTA (n = 1,908) or SE (n = 1,908). Patients were seen in the emergency department (ED) between January 1, 2011, and December 31, 2011 with a primary diagnosis of chest pain and received either CCTA or SE within 72 hours as the first noninvasive test and maintained continuous enrollment in the database from the time of the ED encounter through December 31, 2014. All individual patient data were censored at 3 years. Compared with SE, CCTA was associated with higher odds of downstream cardiac catheterization (9.9% vs 7.7%, adjusted odds ratio [AOR] 1.28, 95% confidence interval (CI) 1.00 to 1.63), future noninvasive testing (27.7% vs 22.3%, AOR 1.22, 95% CI 1.05 to 1.42), and return ED visits or hospitalization for chest pain at 3 years (33.1% vs 24.2%, AOR 1.37, 95% CI 1.19 to 1.59). There were no statistically significant differences in new statin use (15.5% vs 14.9%, AOR 1.04, 95% CI 0.85 to 1.28), coronary revascularization (2.7% vs 2.2%, AOR 1.25, 95% CI 0.77 to 2.01) or hospitalization for acute myocardial infarction (0.9% vs 0.9%, AOR 0.96, 95% CI 0.47 to 1.99). In conclusion, in patients who present to the ED with chest pain, CCTA is associated with increased downstream resource utilization compared with SE with no differences in long-term cardiovascular outcomes.

Abstract
INTRODUCTION Personal digital devices that provide health information, such as the Apple Watch, have developed an increasing array of cardiopulmonary tracking features which have received regulatory clearance and are directly marketed to consumers. Despite their widespread and increasing use, data about the impact of personal digital device use on patient-reported outcomes and healthcare utilisation are sparse. Among a population of patients with atrial fibrillation and/or atrial flutter undergoing cardioversion, our primary aim is to determine the impact of the heart rate measurement, irregular rhythm notification, and ECG features of the Apple Watch on quality of life and healthcare utilisation. METHODS AND ANALYSIS We are conducting a prospective, open-label multicentre pragmatic randomised clinical trial, leveraging a unique patient-centred health data sharing platform for enrolment and follow-up. A total of 150 patients undergoing cardioversion for atrial fibrillation or atrial flutter will be randomised 1:1 to receive the Apple Watch Series 6 or Withings Move at the time of cardioversion. The primary outcome is the difference in the Atrial Fibrillation Effect on QualiTy-of-life global score at 6 months postcardioversion. Secondary outcomes include inpatient and outpatient healthcare utilisation. Additional secondary outcomes include a comparison of the Apple Watch ECG and pulse oximeter features with gold-standard data obtained in routine clinical care settings. ETHICS AND DISSEMINATION The Institutional Review Boards at Yale University, Mayo Clinic, and Duke University Health System have approved the trial protocol. This trial will provide important data to policymakers, clinicians and patients about the impact of the heart rate, irregular rhythm notification, and ECG features of widely used personal digital devices on patient quality of life and healthcare utilisation. Findings will be disseminated to study participants, at professional society meetings and in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT04468321.
