[PMID: 38443911 PMCID: PMC10916275 DOI: 10.1186/s12913-024-10740-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 02/18/2024] [Indexed: 03/07/2024] Open
Abstract
BACKGROUND The decision to screen for breast cancer among older adults with dementia is complex and must often be individualized, as these individuals have an elevated risk of harm from over-screening. Medicare beneficiaries with dementia are increasingly enrolling in Medicare Advantage plans, which typically promote receipt of preventive cancer screening among their enrollees. This study examined the utilization of breast cancer screening among Medicare enrollees with dementia, in Medicare Advantage and in fee-for-service Medicare. METHODS We conducted a pooled cross-sectional study of women with Alzheimer's disease and related dementias or cognitive impairment who were eligible for mammogram screening. We used Medicare Current Beneficiary Survey data to identify utilization of biennial mammogram screening between 2012 and 2019. Poisson regression models were used to estimate prevalence ratios of mammogram utilization and to calculate adjusted mammogram rates for Medicare Advantage and fee-for-service Medicare enrollees with dementia, and further stratified by rurality and by dual eligibility for Medicare and Medicaid. RESULTS Mammogram utilization was 16% higher (Prevalence Ratio [PR] 1.16; 95% CI: 1.05, 1.29) among Medicare Advantage enrollees with dementia, compared to their counterparts in fee-for-service Medicare. Rural enrollees experienced no significant difference (PR 0.99; 95% CI: 0.72, 1.37) in mammogram use between Medicare Advantage and fee-for-service Medicare enrollees. Among urban enrollees, Medicare Advantage enrollment was associated with a 21% higher mammogram rate (PR 1.21; 95% CI: 1.09, 1.35). Dual-eligible Medicare Advantage enrollees had a 34% higher mammogram rate (PR 1.34; 95% CI: 1.10, 1.63) than dual-eligible fee-for-service Medicare enrollees. Among non-dual-eligible enrollees, adjusted mammogram rates were not significantly different (PR 1.11; 95% CI: 0.99, 1.24) between Medicare Advantage and fee-for-service Medicare enrollees. CONCLUSIONS Medicare beneficiaries age 65-74 with Alzheimer's disease and related dementias or cognitive impairment had a higher mammogram use rate when they were enrolled in Medicare Advantage plans compared to fee-for-service Medicare, especially when they were dual-eligible or lived in urban areas. However, some Medicare Advantage enrollees with Alzheimer's disease and related dementias or cognitive impairment may have experienced over-screening for breast cancer.

Abstract
BACKGROUND The early onset of Alzheimer's disease and related dementias (ADRD) before age 65 can introduce life and health care complications. Preserving an early-onset ADRD patient's daily functioning longer and delaying declines in health from non-ADRD conditions become important preventive goals. This study examined the differences in utilization of preventive cancer screenings between patients with and without early-onset ADRD, and compared utilization of the screenings in rural versus urban areas among women with early-onset ADRD in the United States. METHODS We conducted a cross-sectional study of women aged 40 to 64 years eligible for mammogram and cervical cancer screenings using commercial insurance claims from 2012 to 2018. We measured the use of biennial mammogram among women 50 to 64 years old, and the use of triennial Pap smear test among women 40 to 64 years old. We used inverse probability weighted logistic regressions to estimate the odds of receiving preventive cancer screenings by the presence of early-onset ADRD or cognitive impairments (CI). We used multivariable logistic regressions to estimate the odds of receiving preventive cancer screenings by rural or urban residence among women with early-onset ADRD/CI. RESULTS Among 6,349,308 women in the breast cancer screening sample (mean [SD] age, 56.52 [4.03] years), 36,131 had early-onset ADRD/CI (mean [SD] age, 57.99 [3.98] years). Among 6,583,088 women in the cervical cancer screening sample (mean [SD] age, 52.37 [6.81] years), 30,919 had early-onset ADRD/CI (mean [SD] age, 55.79 [6.22] years). Having early-onset ADRD/CI was associated with lower utilization of mammogram (OR: 0.92, 95% CI: 0.90-0.95). No significant difference was observed in Pap smear screening (OR: 0.99, 95% CI: 0.96-1.02) between patients with and without early-onset ADRD/CI. Among patients with early-onset ADRD/CI, those in rural areas were less likely than those in urban areas to have mammograms (OR: 0.91, 95% CI: 0.85-0.97) and Pap smears (OR: 0.65, 95% CI: 0.61-0.71). CONCLUSIONS The observed pattern of rural-urban differences in cancer screening in our study emphasizes the need for efforts to promote evidence-based, individualized decision-making processes in the early-onset ADRD population.

Patterns of staging, treatment, and mortality in gastric, colorectal, and lung cancer among older adults with and without preexisting dementia: a Japanese multicentre cohort study. BMC Cancer 2023; 23:67. [PMID: 36658524 PMCID: PMC9854163 DOI: 10.1186/s12885-022-10411-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Accepted: 12/05/2022] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND Little is known about dementia's impact on patterns of diagnosis, treatment, and outcomes in cancer patients. This study aimed to elucidate the differences in cancer staging, treatment, and mortality in older cancer patients with and without preexisting dementia. METHODS Using cancer registry data and administrative data from 30 hospitals in Japan, this multicentre retrospective cohort study examined patients aged 65-99 years who were newly diagnosed with gastric, colorectal, or lung cancer in 2014-2015. Dementia status (none, mild, and moderate-to-severe) at the time of cancer diagnosis was extracted from clinical summaries in administrative data, and set as the exposure of interest. We constructed multivariable logistic regression models to analyse cancer staging and treatment, and multivariable Cox regression models to analyse three-year survival. RESULTS Among gastric (n = 6016), colorectal (n = 7257), and lung (n = 4502) cancer patients, 5.1%, 5.8%, and 6.4% had dementia, respectively. Patients with dementia were more likely to receive unstaged and advanced-stage cancer diagnoses; less likely to undergo tumour resection for stage I, II, and III gastric cancer and for stage I and II lung cancer; less likely to receive pharmacotherapy for stage III and IV lung cancer; more likely to undergo tumour resection for all-stage colorectal cancer; and more likely to die within three years of cancer diagnosis. The effects of moderate-to-severe dementia were greater than those of mild dementia, with the exception of tumour resection for colorectal cancer. CONCLUSION Older cancer patients with preexisting dementia are less likely to receive standard cancer treatment and more likely to experience poorer outcomes. Clinicians should be aware of these risks, and would benefit from standardised guidelines to aid their decision-making in diagnosing and treating these patients.

Abstract
Background: Colorectal cancer screening can detect colorectal cancer at an early stage and reduce mortality. None of the existing clinical practice guidelines provide specific recommendations for colorectal cancer screening in patients with Alzheimer's disease and related dementias (ADRD). Limited studies have assessed the impacts of ADRD on colorectal cancer screening use and knowledge, and no studies have focused on the associated health disparities. Objectives: To examine the utilization, knowledge, and associated health disparities of colorectal cancer screening in older adults with ADRD. Methods: This study used the Medicare Current Beneficiary Survey from 2015 to 2018. Two types of colorectal cancer screening, including fecal occult blood test (FOBT) and colonoscopy/sigmoidoscopy, were measured. The colorectal cancer screening knowledge was evaluated by asking if the participants have heard of two screening methods and whether they knew Medicare pays for colorectal cancer screenings. Logistic regression models were used to examine the impact of ADRD diagnosis on the utilization and knowledge of colorectal cancer screening. Results: The overall colorectal cancer screening rate in older adults increased from 86.4% to 88.96% from 2015 to 2018. Patients with AD were 39% (OR: 0.61; 95% CI: 0.50-0.76) less likely and those with RD were 25% (OR: 0.75; 95% CI: 0.62-0.91) less likely to use any colorectal cancer screening when compared to older adults without ADRD. The rate of knowledge of colonoscopy/sigmoidoscopy remained high between 84.23% and 84.57% while the knowledge of FOBT increased from 64.32% to 78.69% during the study period. Compared to older adults without ADRD, those with AD were 77% (OR: 1.77; 95% CI: 1.12-2.81) more likely to hear of colonoscopy/sigmoidoscopy. The rate of knowledge of Medicare pay for colorectal cancer screening increased from 42.19% to 45.27% during the study period. Compared to older adults without ADRD, those with AD were 19% (OR: 0.81; 95% CI: 0.70-0.94) less likely to know that Medicare pays for colorectal cancer screening. Conclusion: ADRD was significantly associated with colorectal cancer screening utilization and knowledge. In addition, this study identified health disparities in race/ethnicity, gender, and urban/rural residence in colorectal cancer screening use and knowledge.
