RESUMEN
BACKGROUND: Disparities in opioid prescribing among racial and ethnic groups have been observed in outpatient and emergency department settings, but it is unknown whether similar disparities exist at discharge among hospitalized older adults. OBJECTIVE: To determine filled opioid prescription rates on hospital discharge by race/ethnicity among Medicare beneficiaries. DESIGN: Retrospective cohort study. PARTICIPANTS: Medicare beneficiaries 65 years or older discharged from hospital in 2016, without opioid fills in the 90 days prior to hospitalization (opioid-naïve). MAIN MEASURES: Race/ethnicity was categorized by the Research Triangle Institute (RTI), grouped as Asian/Pacific Islander, Black, Hispanic, other (American Indian/Alaska Native/unknown/other), and White. The primary outcome was an opioid prescription claim within 2 days of hospital discharge. The secondary outcome was total morphine milligram equivalents (MMEs) among adults with a filled opioid prescription. KEY RESULTS: Among 316,039 previously opioid-naïve beneficiaries (mean age, 76.8 years; 56.2% female), 49,131 (15.5%) filled an opioid prescription within 2 days of hospital discharge. After adjustment, Black beneficiaries were 6% less likely (relative risk [RR] 0.94, 95% CI 0.91-0.97) and Asian/Pacific Islander beneficiaries were 9% more likely (RR 1.09, 95% CI 1.03-1.14) to have filled an opioid prescription when compared to White beneficiaries. Among beneficiaries with a filled opioid prescription, mean total MMEs were lower among Black (356.9; adjusted difference - 4%, 95% CI - 7 to - 1%), Hispanic (327.0; adjusted difference - 7%, 95% CI - 10 to - 4%), and Asian/Pacific Islander (328.2; adjusted difference - 8%, 95% CI - 12 to - 4%) beneficiaries when compared to White beneficiaries (409.7). CONCLUSIONS AND RELEVANCE: Black older adults were less likely to fill a new opioid prescription after hospital discharge when compared to White older adults and received lower total MMEs. The factors contributing to these differential prescribing patterns should be investigated further.

BACKGROUND: Inequities in health access and outcomes exist between Indigenous and non-Indigenous populations. Embedded pragmatic randomized, controlled trials (ePCTs) can test the real-world effectiveness of health care interventions. Assessing readiness for ePCT, with tools such as the Readiness Assessment for Pragmatic Trials (RAPT) model, is an important component. Although equity must be explicitly incorporated in the design, testing, and widespread implementation of any health care intervention to achieve equity, RAPT does not explicitly consider equity. This study aimed to identify adaptions necessary for the application of the 'Readiness Assessment for Pragmatic Trials' (RAPT) tool in embedded pragmatic randomized, controlled trials (ePCTs) with Indigenous communities. METHODS: We surveyed and interviewed participants (researchers with experience in research involving Indigenous communities) over three phases (July-December 2022) in this mixed-methods study to explore the appropriateness and recommended adaptions of current RAPT domains and to identify new domains that would be appropriate to include. We thematically analyzed responses and used an iterative process to modify RAPT. RESULTS: The 21 participants identified that RAPT needed to be modified to strengthen readiness assessment in Indigenous research. In addition, five new domains were proposed to support Indigenous communities' power within the research processes: Indigenous Data Sovereignty; Acceptability - Indigenous Communities; Risk of Research; Research Team Experience; Established Partnership). We propose a modified tool, RAPT-Indigenous (RAPT-I) for use in research with Indigenous communities to increase the robustness and cultural appropriateness of readiness assessment for ePCT. In addition to producing a tool for use, it outlines a methodological approach to adopting research tools for use in and with Indigenous communities by drawing on the experience of researchers who are part of, and/or working with, Indigenous communities to undertake interventional research, as well as those with expertise in health equity, implementation science, and public health. CONCLUSION: RAPT-I has the potential to provide a useful framework for readiness assessment prior to ePCT in Indigenous communities. RAPT-I also has potential use by bodies charged with critically reviewing proposed pragmatic research including funding and ethics review boards.

BACKGROUND: Direct oral anticoagulants (DOACs) have comparable efficacy with low-molecular-weight heparin (LMWH) for the treatment of cancer-associated venous thromboembolism (VTE). Whether there is a mortality benefit of DOACs compared with warfarin in the management of VTE in cancer is not established. METHODS AND FINDINGS: Utilizing the United States' Surveillance, Epidemiology, and End Results (SEER)-Medicare linked databases from 2012 through 2016, we analyzed overall survival in individuals diagnosed with a primary gastric, colorectal, pancreas, lung, ovarian, or brain cancer and VTE who received a prescription of DOAC or warfarin within 30 days of VTE diagnosis. Patients were matched 1:2 (DOAC to warfarin) through exact matching for cancer stage and propensity score matching for age, cancer site, cancer stage, and time interval from cancer to VTE diagnosis. The analysis identified 4,274 patients who received a DOAC or warfarin for the treatment of VTE within 30 days of cancer diagnosis (1,348 in DOAC group and 2,926 in warfarin group). Patients were of median age 75 years and 56% female. Within the DOAC group, 1,188 (88%) received rivaroxaban, and 160 (12%) received apixaban. With a median follow-up of 41 months, warfarin was associated with a statistically significantly higher overall survival compared to DOACs (median overall survival 12.0 months [95% confidence interval (CI): 10.9 to 13.5] versus 9.9 months [95% CI: 8.4 to 11.2]; hazard ratio (HR) 0.85; 95% CI: 0.78 to 0.91; p < 0.001). Observed differences in survival were consistent across subgroups of cancer sites, cancer stages, and type of VTE. The study limitations include retrospective design with potential for unaccounted confounders along with issues of generalizability beyond the cancer diagnoses studied. CONCLUSIONS: In this analysis of a population-based registry, warfarin was associated with prolonged overall survival compared to DOACs for treatment of cancer-associated VTE.

BACKGROUND: Patients with dementia are frequently hospitalized and may face barriers in post-discharge care. OBJECTIVE: To determine whether patients with dementia have an increased risk of adverse outcomes following discharge. DESIGN: Retrospective cohort study. SUBJECTS: Medicare beneficiaries hospitalized in 2016. MAIN MEASURES: Co-primary outcomes were mortality and readmission within 30 days of discharge. Multivariable logistic regression models were estimated to assess the risk of each outcome for patients with and without dementia accounting for demographics, comorbidities, frailty, hospitalization factors, and disposition. KEY RESULTS: The cohort included 1,089,109 hospitalizations of which 211,698 (19.3%) were of patients with diagnosed dementia (median (IQR) age 83 (76-89); 61.5% female) and 886,411 were of patients without dementia (median (IQR) age 76 (79-83); 55.0% female). At 30 days following discharge, 5.7% of patients with dementia had died compared to 3.1% of patients without dementia (adjusted odds ratio (aOR) 1.21; 95% CI 1.17 to 1.24). At 30 days following discharge, 17.7% of patients with dementia had been readmitted compared to 13.1% of patients without dementia (aOR 1.02; CI 1.002 to 1.04). Dementia was associated with an increased odds of readmission among patients discharged to the community (aOR 1.07, CI 1.05 to 1.09) but a decreased odds of readmission among patients discharge to nursing facilities (aOR 0.93, CI 0.90 to 0.95). Patients with dementia who were discharged to the community were more likely to be readmitted than those discharged to nursing facilities (18.9% vs 16.0%), and, when readmitted, were more likely to die during the readmission (20.7% vs 4.4%). CONCLUSIONS: Diagnosed dementia was associated with a substantially increased risk of mortality and a modestly increased risk of readmission within 30 days of discharge. Patients with dementia discharged to the community had particularly elevated risk of adverse outcomes indicating possible gaps in post-discharge services and caregiver support.

The concept of guilt has been studied in the context of caregivers of older adults with advanced dementia, usually describing the feelings a person has of placing a loved one in a long-term care facility; however, little research has been done to understand how nursing home staff and proxies for older adults with dementia describe guilt as a decision-influencer in end-of-life care. For the current study, private, semi-structured interviews were conducted with 158 nursing home staff and 44 proxies in 13 nursing homes across four demographic regions in the United States. Interviews were reviewed and analyzed for how the concept of guilt was perceived as a decision-influencer. Nursing home staff described guilt as an important influencer in why proxies make decisions about end-of-life care. Staff noted that proxies who felt guilty about their relationship with their loved one or lack of time spent at end-of-life tended to be more aggressive in care decisions, whereas no proxies mentioned guilt as an influencer in care decisions. Rather, proxies used language of obligation and commitment to describe why they make decisions. Findings highlight the disconnect between nursing home staff and proxies in what motivates proxies to make end-of-life decisions for loved ones. Nursing home staff should be aware of misconceptions about proxies and work to understand proxies' true rationale and motivations for making care decisions.

BACKGROUND: Although analgesics are initiated on hospital discharge in millions of adults each year, studies quantifying the risks of opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) among older adults during this transition are limited. We sought to determine the incidence and risk of post-discharge adverse events among older adults with an opioid claim in the week after hospital discharge, compared to those with NSAID claims only. METHODS AND FINDINGS: We performed a retrospective cohort study using a national sample of Medicare beneficiaries age 65 and older, hospitalized in United States hospitals in 2016. We excluded beneficiaries admitted from or discharged to a facility. We derived a propensity score that included over 100 factors potentially related to the choice of analgesic, including demographics, diagnoses, surgeries, and medication coadministrations. Using 3:1 propensity matching, beneficiaries with an opioid claim in the week after hospital discharge (with or without NSAID claims) were matched to beneficiaries with an NSAID claim only. Primary outcomes included death, healthcare utilization (emergency department [ED] visits and rehospitalization), and a composite of known adverse effects of opioids or NSAIDs (fall/fracture, delirium, nausea/vomiting, complications of slowed colonic motility, acute renal failure, and gastritis/duodenitis) within 30 days of discharge. After propensity matching, there were 13,385 beneficiaries in the opioid cohort and 4,677 in the NSAID cohort (mean age: 74 years, 57% female). Beneficiaries receiving opioids had a higher incidence of death (1.8% versus 1.1%; relative risk [RR] 1.7 [1.3 to 2.3], p < 0.001, number needed to harm [NNH] 125), healthcare utilization (19.0% versus 17.4%; RR 1.1 [1.02 to 1.2], p = 0.02, NNH 59), and any potential adverse effect (25.2% versus 21.3%; RR 1.2 [1.1 to 1.3], p < 0.001, NNH 26), compared to those with an NSAID claim only. Specifically, they had higher relative risk of fall/fracture (4.5% versus 3.4%; RR 1.3 [1.1 to 1.6], p = 0.002), nausea/vomiting (9.2% versus 7.3%; RR 1.3 [1.1 to 1.4], p < 0.001), and slowed colonic motility (8.0% versus 6.2%; RR 1.3 [1.1 to 1.4], p < 0.001). Risks of delirium, acute renal failure, and gastritis/duodenitis did not differ between groups. The main limitation of our study is the observational nature of the data and possibility of residual confounding. CONCLUSIONS: Older adults filling an opioid prescription in the week after hospital discharge were at higher risk for mortality and other post-discharge adverse outcomes compared to those filling an NSAID prescription only.

BACKGROUND: Mortality prediction models are useful to guide clinical decision-making based on prognosis. The frailty index, which allows prognostication and personalized care planning, has not been directly compared with validated prognostic models. OBJECTIVE: To compare the discrimination of mortality, disability, falls, and hospitalization between a frailty index and validated prognostic indices. DESIGN: Secondary Analysis of the National Health and Aging Trends Study. PARTICIPANTS: Seven thousand thirty-three Medicare beneficiaries 65 years or older. MEASUREMENTS: We measured a deficit-accumulation frailty index, Schonberg index, and Lee index at the 2011 baseline assessment. Primary outcome was mortality at 5 years. Secondary outcomes were decline in activities of daily living (ADL), decline in instrumental activities of daily living (IADL), fall, and hospitalization at 1 year. We used C-statistics to compare discrimination between indices, adjusting for age and sex. RESULTS: The study population included 4146 (44.8%) with age ≥ 75 years, with a median frailty index of 0.15 (interquartile range 0.09-0.25). A total of 1385 participants died (14.7%) and 2386 (35.2%) were lost to follow-up. Frailty, Schonberg, and Lee indices predicted mortality similarly: C-statistics (95% confidence interval) were 0.78 (0.77-0.80) for frailty index; 0.79 (0.78-0.81) for Schonberg index; and 0.78 (0.77-0.80) for Lee index. The frailty index had higher C-statistics for decline in ADL function (frailty index, 0.80 [0.78-0.83]; Schonberg, 0.74 [0.72-0.76]; Lee, 0.74 [0.71-0.77]) and falls (frailty index, 0.66 [0.65-0.68]; Schonberg, 0.61 [0.58-0.63]; Lee, 0.61 [0.59-0.63]). C-statistics were similar for decline in IADL function (frailty index, 0.61 [0.59-0.63]; Schonberg, 0.60 [0.59-0.62]; Lee, 0.60 [0.58-0.62]) and hospitalizations (frailty index, 0.68 [0.66-0.70]; Schonberg, 0.68 [0.66-0.69]; Lee, 0.65 [0.63-0.67]). CONCLUSIONS: A deficit-accumulation frailty index performs as well as prognostic indices for mortality prediction, and better predicts ADL disability and falls in community-dwelling older adults. Frailty assessment offers a unifying approach to risk stratification for key health outcomes relevant to older adults.

INTRODUCTION: Nearly 80% of chronic renal failure patients have secondary hyperparathyroidism. Cinacalcet is used to lower parathyroid hormone; however, it is expensive and has side effects. When secondary hyperparathyroidism is resistant to medication or medications are inaccessible, parathyroidectomy is performed. Race and socioeconomic status influence access to care and surgical outcomes. We sought to evaluate the effect of race and socioeconomic status on parathyroidectomy rate as well as surgical outcomes of patients with secondary hyperparathyroidism. METHODS: We undertook cross-sectional analysis of adults diagnosed with secondary hyperparathyroidism in the USA between 2012 and 2014, using the National Inpatient Sample. Univariate and multivariate analyses were used to determine associations between social disparities, likelihood to undergo parathyroidectomy, and surgical outcomes. RESULTS: Between 2012 and 2014, a national estimate of 724,170 hospitalizations were identified where patients had a diagnosis of secondary hyperparathyroidism. Operative rate was 0.67%. By socioeconomic status, differences in rates of surgery in the poorest compared to the richest were not significant (0.74% vs. 0.55%, OR 1.08, p = 0.5). African-American patients had higher rates of parathyroidectomy compared to Caucasians (1 vs. 0.74%, OR 1.49, p < 0.001). African-American patients also had a trend toward more complications and greater length of stay. CONCLUSIONS: According to a large administrative dataset, parathyroidectomy for secondary hyperparathyroidism is seldom used in the USA. African-American patients have higher rates of surgical management. Surgical outcomes may be affected by race. Clinicians treating secondary hyperparathyroidism should be aware of existing disparities within their health system.

OBJECTIVE: To assess the association between meeting the World Health Organization (WHO) maternal antenatal care attendance guidelines and early and middle childhood cognition among impoverished Ethiopian children. STUDY DESIGN: A total of 1914 impoverished Ethiopian children from the Young Lives longitudinal cohort study were included. Childhood cognition was assessed via the Cognitive Development Assessment (CDA) and Peabody Picture Vocabulary Test (PPVT) at ages 4-5 years; PPVT, Early Grade Reading Assessment (EGRA), and Math Test at ages 7-8 years; and PPVT, Math Test, and Reading Test at ages 11-12 years. Linear regression models were used to examine the association between maternal antenatal care attendance and childhood academic achievement test scores. RESULTS: In the univariable analysis, children of mothers who received the WHO recommended 4+ antenatal care visits or received the WHO recommended first antenatal care visit during the first trimester scored higher on all academic achievement tests. In the multivariable analysis, children of mothers who received 4+ antenatal care visits scored significantly higher on the CDA at ages 4-5 years and Math Test at ages 7-8 years. Children of mothers who received antenatal care in the first trimester scored higher on the CDA at ages 4-5 years and Math Test scores at ages 11-12 years. Children of mothers who received both antenatal care in the first trimester and 4+ antenatal care visits scored significantly higher on the CDA at ages 4-5 years and Math Test at both ages 7-8 and 11-12 years. CONCLUSIONS: Children of mothers who received the WHO recommended number and timing of antenatal care visits had significantly higher academic achievement scores across multiple domains during early and middle childhood. Promotion of antenatal care visit attendance may improve cognition through middle childhood.

STUDY OBJECTIVE: To examine the association between race/ethnicity, route of hysterectomy, and risk of inpatient surgical complications. DESIGN: Cross-sectional analysis (Canadian Task Force classification III). SETTING: Inpatient hospitals in the United States. PATIENTS AND INTERVENTIONS: There were 114 719 women aged 18 and older from the Nationwide Inpatient Sample who underwent an elective hysterectomy for benign indications using International Classification of Diseases codes. MEASUREMENTS AND MAIN RESULTS: Multivariable logistic regression was performed to examine the association between race/ethnicity and route of hysterectomy and surgical complications, after adjusting for patient characteristics, clinical factors, and hospital characteristics. Analyses were weighted to provide national estimates of prevalence. The rate of minimally invasive hysterectomy was 55.0% in white women, 28.6% in black women, 50.1% in Hispanic women, and 45.6% in other race/ethnic categories. Compared with white women, black women had a .55 odds (95% confidence interval, .52-.59) of undergoing minimally invasive hysterectomy, after adjusting for patient, clinical, and hospital characteristics. This finding remained consistent across quartiles of median household income of residence, primary payer, and diagnosis of myomas. Among women who had an elective hysterectomy, 6091 experienced a complication, representing an estimated 30 455 women nationwide. The rate of surgical complications was 5.3% in white women, 5.9% in black women, 4.6% in Hispanic women, and 5.1% in women of other racial/ethnic groups. There was no difference in odds of experiencing a surgical complication between white and black women (odds ratio, 1.03; 95% confidence interval, .93-1.13) after adjusting for patient, clinical, and hospital characteristics. This finding remained consistent across quartiles of median household income of residence, primary payer, and route of hysterectomy. CONCLUSION: Among women undergoing an elective hysterectomy, black women were less likely to receive minimally invasive hysterectomy compared with white women. However, the rate of inpatient surgical complications did not vary significantly by race/ethnicity. Further research is encouraged to identify and address the influential factors behind the disparity in minimally invasive hysterectomy use among black women in the United States.

PURPOSE: Accurate risk assessment is necessary for decision-making around breast cancer prevention. We aimed to develop a breast cancer prediction model for postmenopausal women that would take into account their individualized competing risk of non-breast cancer death. METHODS: We included 73,066 women who completed the 2004 Nurses' Health Study (NHS) questionnaire (all ≥57 years) and followed participants until May 2014. We considered 17 breast cancer risk factors (health behaviors, demographics, family history, reproductive factors) and 7 risk factors for non-breast cancer death (comorbidities, functional dependency) and mammography use. We used competing risk regression to identify factors independently associated with breast cancer. We validated the final model by examining calibration (expected-to-observed ratio of breast cancer incidence, E/O) and discrimination (c-statistic) using 74,887 subjects from the Women's Health Initiative Extension Study (WHI-ES; all were ≥55 years and followed for 5 years). RESULTS: Within 5 years, 1.8 % of NHS participants were diagnosed with breast cancer (vs. 2.0 % in WHI-ES, p = 0.02), and 6.6 % experienced non-breast cancer death (vs. 5.2 % in WHI-ES, p < 0.001). Using a model selection procedure which incorporated the Akaike Information Criterion, c-statistic, statistical significance, and clinical judgement, our final model included 9 breast cancer risk factors, 5 comorbidities, functional dependency, and mammography use. The model's c-statistic was 0.61 (95 % CI [0.60-0.63]) in NHS and 0.57 (0.55-0.58) in WHI-ES. On average, our model under predicted breast cancer in WHI-ES (E/O 0.92 [0.88-0.97]). CONCLUSIONS: We developed a novel prediction model that factors in postmenopausal women's individualized competing risks of non-breast cancer death when estimating breast cancer risk.

BACKGROUND: Insurance impacts access to therapeutic options, yet little is known about how healthcare reform might change the pattern of surgical admissions. OBJECTIVE: We compared rates of emergent admissions and outcomes after colectomy before and after reform in Massachusetts with a nationwide control group. DESIGN: This study is a retrospective cohort analysis in a natural experiment. Prereform was defined as hospital discharge from 2002 through the second quarter of 2006 and postreform from the third quarter of 2006 through 2012. Categorical variables were compared by χ. Piecewise functions were used to test the effect of healthcare reform on the rate of emergent surgeries. SETTINGS: The study included acute care hospitals in the Massachusetts Healthcare Cost and Utilization Project State Inpatient Database (2002-2012) and the Nationwide Inpatient Sample (2002-2011). PATIENTS: Patients aged 18 to 64 years with public or no insurance who underwent inpatient colectomy (via International Classification of Diseases, Ninth Revision, Clinical Modification procedural code) were included and patients with Medicare were excluded. INTERVENTION: Massachusetts health care reform was the study intervention. MAIN OUTCOME MEASURES: We measured the rate of emergent colectomy, complications, and mortality. RESULTS: The unadjusted rate of emergent colectomies was lower in Massachusetts after reform but did not change nationally over the same time period. For emergent surgeries in Massachusetts, a piecewise model with an inflection point (peak) in the third quarter of 2006, coinciding with implementation of healthcare reform in Massachusetts, had a lower mean squared error than a linear model. In comparison, the national rate of emergent surgeries demonstrated no change in pattern. Postreform, length of stay decreased by 1 day in Massachusetts; however, there were no significant improvements in other outcomes. LIMITATIONS: The study was limited by its retrospective design and unadjusted analysis. CONCLUSIONS: There was a unique and sustained decline in the rate of emergent colon resection among publically insured and uninsured patients after 2006 in Massachusetts, in contradistinction to the national pattern, suggesting improved access to care associated with health insurance expansion. The reasons for lack of improvement in outcomes are multifactorial.

BACKGROUND: Headache is a frequent complaint and among the most common reasons for visiting a physician. OBJECTIVE: To characterize trends from 1999 through 2010 in the management of headache. DESIGN: Longitudinal trends analysis. DATA: Nationally representative sample of visits to clinicians for headache from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, excluding visits with "red flags," such as neurologic deficit, cancer, or trauma. MAIN MEASURES: Use of advanced imaging (CT/MRI), opioids/barbiturates, and referrals to other physicians (guideline-discordant indicators), as well as counseling on lifestyle modifications and use of preventive medications including verapamil, topiramate, amitriptyline, or propranolol (guideline-concordant during study period). We analyzed results using logistic regression, adjusting for patient and clinician characteristics, and weighted to reflect U.S. population estimates. Additionally, we stratified findings based on migraine versus non-migraine, acute versus chronic symptoms, and whether the clinician self-identified as the primary care physician. KEY RESULTS: We identified 9,362 visits for headache, representing an estimated 144 million visits during the study period. Nearly three-quarters of patients were female, and the mean age was approximately 46 years. Use of CT/MRI rose from 6.7% of visits in 1999-2000 to 13.9% in 2009-2010 (unadjusted p < 0.001), and referrals to other physicians increased from 6.9 % to 13.2% (p = 0.005). In contrast, clinician counseling declined from 23.5 % to 18.5% (p = 0.041). Use of preventive medications increased from 8.5 % to 15.9% (p = 0.001), while opioids/barbiturates remained unchanged, at approximately 18%. Adjusted trends were similar, as were results after stratifying by migraine versus non-migraine and acute versus chronic presentation. Primary care clinicians had lower odds of ordering CT/MRI (OR 0.56 [0.42, 0.74]). CONCLUSIONS: Contrary to numerous guidelines, clinicians are increasingly ordering advanced imaging and referring to other physicians, and less frequently offering lifestyle counseling to their patients.

BACKGROUND: Utilization of primary care may decrease colorectal cancer (CRC) incidence and death through greater receipt of CRC screening tests. OBJECTIVE: To examine the association of primary care utilization with CRC incidence, CRC deaths, and all-cause mortality. DESIGN: Population-based, case-control study. SETTING: Medicare program. PARTICIPANTS: Persons aged 67 to 85 years diagnosed with CRC between 1994 and 2005 in U.S. Surveillance, Epidemiology, and End Results (SEER) regions matched with control patients (n = 205,804 for CRC incidence, 54,160 for CRC mortality, and 121,070 for all-cause mortality). MEASUREMENTS: Primary care visits in the 4- to 27-month period before CRC diagnosis, CRC incidence, CRC mortality, and all-cause mortality. RESULTS: Compared with persons having 0 or 1 primary care visit, persons with 5 to 10 visits had lower CRC incidence (adjusted odds ratio [OR], 0.94 [95% CI, 0.91 to 0.96]) and mortality (adjusted OR, 0.78 [CI, 0.75 to 0.82]) and lower all-cause mortality (adjusted OR, 0.79 [CI, 0.76 to 0.82]). Associations were stronger in patients with late-stage CRC diagnosis, distal lesions, and diagnosis in more recent years when there was greater Medicare screening coverage. Ever receipt of CRC screening and polypectomy mediated the association of primary care utilization with CRC incidence. LIMITATION: This study used administrative data, which made it difficult to identify potential confounders and prevented examination of the content of primary care visits. CONCLUSION: Medicare beneficiaries with higher utilization of primary care have lower CRC incidence and mortality and lower overall mortality. Increasing and promoting access to primary care in the United States for Medicare beneficiaries may help decrease the national burden of CRC. PRIMARY FUNDING SOURCE: American Cancer Society.

Importance: A growing proportion of the population is enrolling in Medicare Advantage (MA), which typically offers additional benefits compared with traditional Medicare (TM). Objective: To determine whether frailty and frailty trajectories differ between MA enrollees and TM enrollees. Design, Setting, and Participants: This retrospective cohort study used data from the National Health and Aging Trends Study (2015-2016). Analyses were conducted from August 2023 to March 2024. Participants were community-dwelling Medicare beneficiaries aged 65 years and older. Exposure: Enrollment in MA vs TM. Main Outcomes and Measures: Frailty was calculated by a frailty index (FI) (range, 0-1, with higher values indicating greater frailty) and the Fried Frailty Phenotype (FFP) score (range, 0-5, with higher values indicating greater frailty). Physical performance, including Short Physical Performance Battery (SPPB) score (range, 0-12, with higher values indicating better performance), and gait speed (meters per second) were measured. The primary outcome was the difference in FI and FFP scores from the 2015 baseline assessment to the 2016 follow-up assessment. Secondary outcomes include the 1-year changes in SPPB and gait speed. Results: The final cohort consisted of 7063 participants (2775 [23.1%] aged >80 years; 4040 [54.7%] female), representing a sample of the 38.8 million beneficiaries. There were 2583 (35.0%) MA enrollees (13.6 million) and 4480 (65.0%) TM enrollees (25.2 million). At baseline, the FI score was similar between MA and TM enrollees (mean [SD], 0.22 [0.15] vs 0.21 [0.14]), although MA enrollees had worse phenotypic frailty (496 participants [15.2%] vs 811 participants [13.7%] considered frail by FFP score), SPPB scores (mean [SD], 6.91 [3.34] vs 7.21 [3.27]), and gait speed (0.79 [0.24] m/s vs 0.82 [0.23] m/s) than TM enrollees. One year later, there were no differences between MA and TM enrollees in the 1-year change in FI score (mean [SD], 0.016 [0.071] vs 0.014 [0.066]; adjusted mean difference, 0.001 [95% CI, -0.004 to 0.005]), FFP score (mean [SD], 0.017 [1.004] vs 0.007 [0.958]; adjusted mean difference, -0.009 [95% CI, -0.067 to 0.049]), SPPB score (mean [SD], -0.144 [2.064] vs -0.211 [1.968]; adjusted mean difference, 0.068 [95% CI, -0.076 to 0.212]), and gait speed (mean [SD], -0.0160 [0.148] m/s vs -0.007 [0.148] m/s; adjusted mean difference, -0.010 m/s [95% CI, -0.067 to 0.049 m/s]). Conclusions and Relevance: In this cohort study of Medicare beneficiaries from 2015, MA enrollees experienced similar declines in frailty over 1 year compared with TM enrollees. Future work should examine whether the specific types of services covered by health insurance can impact frailty and health trajectories for older adults.

OBJECTIVE: Previous research using the National Health and Aging Trends Study showed that a claims-based frailty index (CFI) could be useful for identifying moderate-to-severe dementia in Medicare claims data. This study aims to validate the findings in an independent cohort. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: The study included 658 fee-for-service beneficiaries with dementia who participated in the 2016-2020 Medicare Current Beneficiary Survey in the community-dwelling. METHODS: We operationalized the Functional Assessment Staging Test (FAST) scale (range: 1-7, stages 5-7 indicate moderate-to-severe dementia) using survey information. CFI (range: 0-1, higher scores indicate greater frailty) was calculated using Medicare claims 12 months before the participants' interview date. Using the previously proposed cut point of 0.280, we calculated sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for identifying moderate-to-severe dementia. Survey procedures were used to account for survey design and weighted to reflect national estimates. RESULTS: The population had a mean age (SD) of 80.7 (8.9) years, 58.5% female, and 101 beneficiaries (14.8%) had moderate-to-severe dementia. The CFI cut point of 0.280 demonstrated sensitivity 0.49 (95% CI, 0.38-0.59), specificity 0.80 (0.77-0.84), PPV 0.30 (0.23-0.38), and NPV 0.90 (0.87-0.93). Compared with those with a CFI <0.280, beneficiaries with a CFI ≥0.280 had an elevated risk of mortality (2.9% vs 4.1%) over 1 year. CONCLUSIONS AND IMPLICATIONS: These results confirm our previous findings that CFI among beneficiaries with a dementia diagnosis is a useful measure of moderate-to-severe dementia for Medicare claims data.
RESUMEN
INTRODUCTION: Research efforts to characterize and evaluate care delivery and outcomes for older adults with cancer and comorbid dementia are limited by varied methods used to classify Alzheimer's disease and related dementias (ADRD). The purpose of this study is to evaluate differences in demographic, clinical, and cancer characteristics of people newly diagnosed with cancer and concomitant dementia comparing two common methods to identify ADRD using administrative claims data. MATERIALS AND METHODS: We conducted a retrospective cohort study using Surveillance, Epidemiology, and End Results (SEER)-Medicare data. Our sample included adults aged 66 years and older with a first primary diagnosis of lung or colorectal cancer between 2011 and 2017. For each cancer diagnosis, we constructed analytical cohorts using the Center for Medicare and Medicaid Services' Chronic Condition Warehouse (CCW) flag and the Bynum-Standard one- and three-year algorithms to capture diagnosed ADRD. We estimated ADRD prevalence using the algorithms and compared Bynum and CCW cohorts on demographic, clinical, and cancer characteristics at cancer diagnosis and survival for lung and colorectal cancer separately. RESULTS: Among older adults with lung cancer, ADRD prevalence was 4.7% with the one-year Bynum, 6.5% with the three-year Bynum, and 12.5% using the CCW flag. In the colorectal cohort, ADRD prevalence was 5.6% with the one-year Bynum, 7.6% with the three-year Bynum, and 14.1% with the CCW flag. Demographic characteristics were similar across ADRD cohorts. The Bynum cohorts identified higher proportions of individuals with moderate to severe dementia (13.8% and 11.2% versus 7.1% CCW in lung cancer; 13.1% and 10.6% versus 6.8% CCW in colorectal cancer), higher frailty rates (27.4% and 22.7% versus 15.0% CCW in lung cancer; 26.4% and 22.3% versus 14.8% CCW in colorectal cancer). Median survival was lower for the Bynum cohorts compared to the CCW, regardless of cancer type. DISCUSSION: Findings demonstrate that ADRD prevalence and certain clinical characteristics vary based on dementia ascertainment method and observation period used to classify individuals with ADRD. Considering differences in the cohorts of registry cases generated by the identification method used is essential when interpreting findings related to treatment, utilization, and outcomes within and across cancer cohorts.

Underdiagnosis, misdiagnosis, and patterns of social inequality that translate into unequal access to health systems all pose barriers to identifying and recruiting diverse and representative populations into research on Alzheimer's disease and Alzheimer's disease related dementias. In response, some have turned to algorithms to identify patients living with dementia using information that is associated with this condition but that is not as specific as a diagnosis. This paper explains six ethical issues associated with the use of such algorithms including the generation of new, sensitive, identifiable medical information for research purposes without participant consent, issues of justice and equity, risk, and ethical communication. It concludes with a discussion of strategies for addressing these issues and prompting valuable research.

BACKGROUND: The relationship of claims-based frailty index (CFI), a validated measure to identify frail individuals using Medicare data, and frailty measures used in clinical practice has not yet been fully explored. METHODS: We identified community-dwelling participants of the 2015 National Health and Aging Trends Study (NHATS) whose CFI scores could be calculated using linked Medicare claims. We calculated 9 commonly used clinical frailty measures from their NHATS in-person examination: Study of Osteoporotic Fracture Index (SOF), FRAIL Scale, Frailty Phenotype, Clinical Frailty Scale (CFS), Vulnerable Elder Survey-13 (VES-13), Tilburg Frailty Indicator (TFI), Groningen Frailty Indicator (GFI), Edmonton Frail Scale (EFS), and 40-item Frailty Index (FI). Using equipercentile method, CFI scores were linked to clinical frailty measures. C-statistics and test characteristics of CFI to identify frailty as defined by each clinical frailty measure were calculated. RESULTS: Of the 3 963 older adults, 44.5% were ≥75 years, 59.4% were female, and 82.3% were non-Hispanic White. A CFI of 0.25 was equipercentile to the following clinical frailty measure scores: SOF 1.4, FRAIL 1.8, Phenotype 1.8, CFS 5.4, VES-13 5.7, TFI 4.6, GFI 5.0, EFS 6.0, and FI 0.26. The C-statistics of using CFI to identify frailty as defined by each clinical measure were ≥0.70, except for CFS and VES-13. The optimal CFI cutpoints to identify frailty per clinical frailty measure ranged from 0.212 to 0.242, with sensitivity and specificity of 0.37-0.83 and 0.66-0.84, respectively. CONCLUSIONS: Understanding the relationship of CFI and commonly used clinical frailty measures can enhance the interpretability and potential utility of CFI.
