Cervical cancer screening utilization among kidney transplant recipients, 2001-2018.

BACKGROUND: Kidney transplant recipients (KTRs) have elevated risks of cervical pre-cancers and cancers, and guidelines recommend more frequent cervical cancer screening exams. However, little is known about current trends in cervical cancer screening in this unique population. We described patterns in the uptake of cervical cancer screening exams among female KTRs and identified factors associated with screening utilization. METHODS: This retrospective cohort study included female KTRs between 20-65 years old, with Texas Medicare fee-for-service coverage, who received a transplant between January 1, 2001, and December 31, 2017. We determined the cumulative incidence of receiving cervical cancer screening post-transplant using ICD-9, ICD-10, and CPT codes and assessed factors associated with screening utilization, using the Fine and Gray model to account for competing events. Subdistribution hazards models were used to assess factors associated with screening uptake. RESULTS: Among 2,653 KTRs meeting the inclusion and exclusion criteria, the 1-, 2-, and 3-year cumulative incidences of initiating a cervical cancer screening exam post-transplant were 31.7% (95% confidence interval (CI), 30.0-33.6%), 48.0% (95% CI, 46.2-49.9%), and 58.5% (95% CI, 56.7-60.3%), respectively. KTRs who were 55-64 years old (vs. <45 years old) and those with a higher Charlson Comorbidity Score post-transplant were less likely to receive cervical cancer screening post-transplant. CONCLUSIONS: Cervical cancer screening uptake is low in the years immediately following a kidney transplant. IMPACT: Our findings highlight a need for interventions to improve cervical cancer screening utilization among KTRs.

Central nervous system active medication use in Medicare enrollees receiving home health care: association with chronic pain and anxiety level.

ABSTRACT: No comparative effectiveness data exist on nonopioid analgesics and nonbenzodiazepine anxiolytics to treat pain with anxiety. We examined the relationship between drug class and central nervous system (CNS) active drug polypharmacy on pain and anxiety levels in Medicare enrollees receiving home health (HH) care. This retrospective cohort study included enrollees with diagnoses and 2+ assessments of pain and anxiety between HH admission and discharge. Three sets of linear regression difference-in-reduction analyses assessed the association of pain or anxiety reduction with number of drugs; drug type; and drug combinations in those with daily pain and daily anxiety. Logistic regression analysis assessed the effect of medication number and class on less-than-daily pain or anxiety at HH discharge. A sensitivity analysis using multinomial regression was conducted with a three-level improvement to further determine clinical significance. Of 85,403 HH patients, 43% received opioids, 27% benzodiazepines, 26% gabapentinoids, 32% selective serotonin reuptake inhibitors, and 8% serotonin and norepinephrine reuptake inhibitors (SNRI). Furthermore, 75% had depression, 40% had substance use disorder diagnoses, and 6.9% had PTSD diagnoses. At HH admission, 83%, 35%, and 30% of patients reported daily pain, daily anxiety, and both, respectively. Central nervous system polypharmacy was associated with worse pain control and had no significant effect on anxiety. For patients with daily pain plus anxiety, pain was best reduced with one medication or any drug combination without opioid/benzodiazepine; anxiety was best reduced with combinations other than opiate/benzodiazepine. Gabapentinoids or SNRI achieved clinically meaningful pain control. Selective serotonin reuptake inhibitors provided clinically meaningful anxiety relief.

Patterns of gabapentinoid use among long-term opioid users.

OBJECTIVE: Understanding the clinical and demographic profile of patients on gabapentinoids can highlight areas of prescribing disparities, inform clinical practice, and guide future research to optimize effectiveness and safety of gabapentinoids for pain management. We used a national sample of Medicare beneficiaries to examine trends, patterns, and patient-level predictors of gabapentinoid use among long-term opioid users. METHODS: Using a national Medicare sample between 2014 and 2020, we examined factors associated with gabapentinoid use among long-term opioid users. We included Medicare eligible long-term opioid users with no prior gabapentinoid use. The primary outcome was gabapentinoid use after the long-term opioid use episode. Logistic regression was used to test the association with gabapentinoid use for year, age, sex, race/ethnicity, region, Medicare entitlement, low-income status, frailty, pain locations, anxiety, depression, opioid use disorder, and opioid morphine milligrams equivalent. RESULTS: Gabapentinoid use among long-term opioid users increased from 12.6% in 2014 to 16.8% in 2019 (p < .0001). Factors associated with increased gabapentinoid use were Hispanic ethnicity, back pain, nerve pain, and moderate or high opioid usage. Factors associated with decreased gabapentinoid use were older age and Medicare entitlement due to old age. CONCLUSIONS: Variation of gabapentinoid use by socio-demographics and insurance status indicates opportunities to improve pain management and a need for shared therapeutic decision making informed by discussion between pain patients and providers regarding safety and effectiveness of pain therapies. Our findings underscore the need for future research into the comparative effectiveness and safety of gabapentinoids for non-cancer chronic pain in various subpopulations.

Association of cancer diagnosis with disability status among older survivors of colorectal cancer: a population-based retrospective cohort study.

Background: Older cancer survivors likely experience physical function limitations due to cancer and its treatments, leading to disability and early mortality. Existing studies have focused on factors associated with surgical complications and mortality risk rather than factors associated with the development of poor disability status (DS), a proxy measure of poor performance status, in cancer survivors. We aimed to identify factors associated with the development of poor DS among older survivors of colorectal cancer (CRC) and compare poor DS rates to an age-sex-matched, non-cancer cohort. Methods: This retrospective cohort study utilized administrative data from the Texas Cancer Registry Medicare-linked database. The study cohort consisted of 13,229 survivors of CRC diagnosed between 2005 and 2013 and an age-sex-matched, non-cancer cohort of 13,225 beneficiaries. The primary outcome was poor DS, determined by Davidoff's method, using predictors from 12 months of Medicare claims after cancer diagnosis. Multivariable Cox proportional hazards regression was used to identify risk factors associated with the development of poor DS. Results: Among the survivors of CRC, 97% were 65 years or older. After a 9-year follow-up, 54% of survivors of CRC developed poor DS. Significant factors associated with future poor DS included: age at diagnosis (hazard ratio [HR] = 3.50 for >80 years old), female sex (HR = 1.50), race/ethnicity (HR = 1.34 for Hispanic and 1.21 for Black), stage at diagnosis (HR = 2.26 for distant metastasis), comorbidity index (HR = 2.18 for >1), and radiation therapy (HR = 1.21). Having cancer (HR = 1.07) was significantly associated with developing poor DS in the pooled cohorts; age and race/ethnicity were also significant factors. Conclusions: Our findings suggest that a CRC diagnosis is independently associated with a small increase in the risk of developing poor DS after accounting for other known factors. The study identified risk factors for developing poor DS in CRC survivors, including Hispanic and Black race/ethnicity, age, sex, histologic stage, and comorbidities. These findings underscore the importance of consistent physical function assessments, particularly among subsets of older survivors of CRC who are at higher risk of disability, to prevent developing poor DS.

Temporal Trends in Treatment and Outcomes of Endometrial Carcinoma in the United States, 2005-2020.

Endometrial cancer has continued to see a rising incidence in the US over the years. The main aim of this study was to assess current trends in patients' characteristics and outcomes of treatment for endometrial carcinoma over 16 years. A dataset from the National Cancer Database (NCDB) for patients diagnosed with endometrial carcinoma from 2005 to 2020 was used in this retrospective, case series study. The main outcomes and measures of interest included tumor characteristics, hospitalization, treatments, mortality, and overall survival. Then, 569,817 patients who were diagnosed with endometrial carcinoma were included in this study. The mean (SD) age at diagnosis was 62.7 (11.6) years, but 66,184 patients (11.6%) were younger than 50 years, indicating that more patients are getting diagnosed at younger ages. Of the patients studied, 37,079 (6.3%) were Hispanic, 52,801 (9.3%) were non-Hispanic Black, 432,058 (75.8%) were non-Hispanic White, and 48,879 (8.6%) were other non-Hispanic. Patients in the 4th period from 2017 to 2020 were diagnosed more with stage IV (7.1% vs. 5.2% vs. 5.4% vs. 5.9%; p < 0.001) disease compared with those in the other three periods. More patients with severe comorbidities (Charlson Comorbidity Index score of three) were seen in period 4 compared to the first three periods (3.9% vs. ≤1.9%). Systemic chemotherapy use (14.1% vs. 17.7% vs. 20.4% vs. 21.1%; p < 0.001) and immunotherapy (0.01% vs. 0.01% vs. 0.2% vs. 1.1%; p < 0.001) significantly increased from period 1 to 4. The use of laparotomy decreased significantly from 42.1% in period 2 to 16.7% in period 4, while robotic surgery usage significantly increased from 41.5% in period 2 to 64.3% in period 4. The 30-day and 90-day mortality decreased from 0.6% in period 1 to 0.2% in period 4 and 1.4% in period 1 to 0.6% in period 4, respectively. Over the period studied, we found increased use of immunotherapy, chemotherapy, and minimally invasive surgery for the management of endometrial cancer. Overall, the time interval from cancer diagnosis to final surgery increased by about 6 days. The improvements observed in the outcomes examined can probably be associated with the treatment trends observed.

Cost-Effectiveness of Population-Based Multigene Testing for Breast and Ovarian Cancer Prevention.

Importance: The current method of BRCA testing for breast and ovarian cancer prevention, which is based on family history, often fails to identify many carriers of pathogenic variants. Population-based genetic testing offers a transformative approach in cancer prevention by allowing for proactive identification of any high-risk individuals and enabling early interventions. Objective: To assess the lifetime incremental effectiveness, costs, and cost-effectiveness of population-based multigene testing vs family history-based testing. Design, Setting, and Participants: This economic evaluation used a microsimulation model to assess the cost-effectiveness of multigene testing (BRCA1, BRCA2, and PALB2) for all women aged 30 to 35 years compared with the current standard of care that is family history based. Carriers of pathogenic variants were offered interventions, such as magnetic resonance imaging with or without mammography, chemoprevention, or risk-reducing mastectomy and salpingo-oophorectomy, to reduce cancer risk. A total of 2000 simulations were run on 1 000 000 women, using a lifetime time horizon and payer perspective, and costs were adjusted to 2022 US dollars. This study was conducted from September 1, 2020, to December 15, 2023. Main Outcomes and Measures: The main outcome measure was the incremental cost-effectiveness ratio (ICER), quantified as cost per quality-adjusted life-year (QALY) gained. Secondary outcomes included incremental cost, additional breast and ovarian cancer cases prevented, and excess deaths due to coronary heart disease (CHD). Results: The study assessed 1 000 000 simulated women aged 30 to 35 years in the US. In the base case, population-based multigene testing was more cost-effective compared with family history-based testing, with an ICER of $55 548 per QALY (95% CI, $47 288-$65 850 per QALY). Population-based multigene testing would be able to prevent an additional 1338 cases of breast cancer and 663 cases of ovarian cancer, but it would also result in 69 cases of excess CHD and 10 excess CHD deaths per million women. The probabilistic sensitivity analyses show that the probability that population-based multigene testing is cost-effective was 100%. When the cost of the multigene test exceeded $825, population-based testing was no longer cost-effective (ICER, $100 005 per QALY; 95% CI, $87 601-$11 6323). Conclusions and Relevance: In this economic analysis of population-based multigene testing, population-based testing was a more cost-effective strategy for the prevention of breast cancer and ovarian cancer when compared with the current family history-based testing strategy at the $100 000 per QALY willingness-to-pay threshold. These findings support the need for more comprehensive genetic testing strategies to identify pathogenic variant carriers and enable informed decision-making for personalized risk management.

Evaluating the impact of pre-diagnostic use of statins and testosterone replacement therapy on mortality outcomes in older men with hormone-related cancers: Surveillance, Epidemiology, and End Results-Medicare 2007-2015.

BACKGROUND: The link between the pre-diagnostic use of statins and testosterone replacement therapy and their impact on hormone-related cancers, prostate cancer, colorectal cancer, and male breast cancer survival remains a topic of controversy. Further, there is a knowledge gap concerning the joint effects of statins and testosterone replacement therapy on hormone-related cancer survival outcomes. OBJECTIVE: To examine the independent and joint effects of pre-diagnostic use of statins and testosterone replacement therapy on the risk of all-cause and cause-specific mortality among older men diagnosed with hormone-related cancers, including prostate cancer, colorectal cancer, and male breast cancer. METHODS: In 41,707 men (≥65 years) of Surveillance, Epidemiology, and End Results-Medicare 2007-2015, we identified 31,097 prostate cancer, 10,315 colorectal cancer, and 295 male breast cancer cases. Pre-diagnostic prescription of statins and testosterone replacement therapy was ascertained and categorized into four groups (Neither users, statins alone, testosterone replacement therapy alone, and Dual users). Multivariable-adjusted Cox proportional hazards and competing-risks (Fine-Gray subdistribution hazard) models were conducted. RESULTS: No significant associations were found in Cox-proportional hazard models for hormone-related cancers. However, in the Fine-Gray competing risk models among high-grade hormone-related cancers, statins alone had an 11% reduced risk of hormone-related cancer-specific death (hazard ratio: 0.89; 95% confidence interval: 0.81-0.99; p 0.0451). In the prostate cancer cohort with both statistical models, the use of testosterone replacement therapy alone had a 24% lower risk of all-cause death (hazard ratio: 0.76; 95% confidence interval: 0.59-0.97; p 0.0325) and a 57% lower risk of prostate cancer-specific death (hazard ratio: 0.43; 95% confidence interval: 0.24-0.75; p 0.0029). Similar inverse associations were found among aggressive prostate cancer cases with testosterone replacement therapy alone and statins alone. No significant associations were found in the colorectal cancer and male breast cancer sub-groups. CONCLUSION: Pre-diagnostic use of statins and testosterone replacement therapy showed a survival benefit with reduced mortality in high-grade hormone-related cancer patients (only statins) and aggressive prostate cancer patients in both statistical models. Findings of testosterone replacement therapy use in aggressive prostate cancer settings could facilitate clinical trials. Further studies with extended follow-up periods are needed to substantiate these findings.

Immunogenicity of 2 or 3 Doses of 9vHPV Vaccine in U.S. Female Individuals 15 to 26 Years of Age.

BACKGROUND: Within the United States, a 9-valent human papillomavirus (9vHPV) vaccine (HPV-6/11/16/18/31/33/45/52/58) is recommended as a two-dose series among individuals 9 to 14 years of age and a three-dose series among those 15 to 26 years of age. Data comparing two versus three doses of 9vHPV vaccine among individuals 15 to 26 years of age are limited. METHODS: We report on an ongoing, single-blinded, randomized noninferiority trial of the 9vHPV vaccine among individuals 15 to 26 years of age in the United States. Participants were randomly assigned to a two-dose (0 and 6 months) or three-dose (0, 2, and 6 months) schedule. Blood draws to assess antibody titers were planned before the first vaccination and at 1 and 6 months after the final vaccination. The primary outcome was the rate of seroconversion at 1 month after final vaccination. The secondary outcome was the two-dose versus three-dose ratio of antibody geometric mean titers (GMTs) for each of the 9vHPV genotypes at 1 and 6 months after final vaccination. This interim analysis reports results of female participants at 1 month after final vaccination. RESULTS: Of 860 participants screened, 438 were enrolled and randomly assigned to the two-dose (n=217) or three-dose (n=221) group. At 1 month after the final vaccine dose, the seroconversion rate for each of the nine HPV genotypes in the vaccine was 100% among participants in the two-dose group and 99% in the three-dose group. The point estimates of the two-dose versus three-dose ratios of antibody GMTs for eight of the nine HPV genotypes were above unity; the ratio for HPV-45 was 0.86 (95% confidence interval [CI], 0.66 to 1.13). This was also the smallest value for the lower bound of the 95% CI for all nine ratios (ratios above 1 favor the two-dose schedule). No serious adverse events were observed. CONCLUSIONS: In this unplanned interim analysis of U.S. female participants 15 to 26 years of age, two doses of 9vHPV vaccine appear to elicit responses similar to three doses at 1 month postvaccination. We await final results at 6 months following the last vaccine dose. (ClinicalTrials.gov number, NCT03943875.)

Factors associated with longer survival among older medicare patients after diagnosis of supratentorial primary brain malignancies: a retrospective cohort study.

OBJECTIVES: Despite recent advances, the prognosis for primary malignant brain tumors (PMBTs) remains poor. Some commonly prescribed medications may exhibit anti-tumor properties in various cancers, and neurodegenerative diseases may activate pathways that counteract gliomagenesis. Our study is focused on determining if there is a correlation between the use of metformin, beta-blockers, angiotensin converting enzyme inhibitors (ACEIs), and angiotensin receptor blockers (ARBs), or the presence of Parkinson's disease (PD), and the survival rates following a diagnosis of a PMBT. METHODS: This analysis of the 100% Texas Medicare Database identified patients aged 66+ years diagnosed with a supratentorial PMBT from 2014-2017. Cox proportional hazards regression was employed to analyze survival following diagnosis and associations of survival with surgical intervention, radiation, PD diagnosis, and prescription of metformin, beta-blockers, ACEIs, or ARBs. RESULTS: There were 1,943 patients who met study criteria, and the median age was 74 years. When medication utilization was stratified by none, pre-diagnosis only, post-diagnosis only, or both pre- and post-diagnosis (continuous), continuous utilization of metformin, beta-blockers, ACEIs, or ARBs was associated with prolonged survival compared to no utilization (hazard ratio [HR]:0.45, 95% CI:0.33-0.62; HR:0.71. 95% CI:0.59-0.86; HR:0.59, 95% CI:0.48-0.72; and HR:0.45, 95% CI:0.35-0.58 respectively). PD was also associated with longer survival (HR:0.59-0.63 across the four models). DISCUSSION: Our study suggests that metformin, beta-blockers, ACEIs, ARBs, and comorbid PD are associated with a survival benefit among geriatric Medicare patients with supratentorial PMBTs.

Pain Control Associated With Gabapentinoid Prescription After Elective Total Knee Arthroplasty.

BACKGROUND: Gabapentinoid (GABA) prescribing has substantially increased as a nonopioid analgesics for surgical conditions. We examined the effectiveness of GABA use for postoperative pain control among patients receiving total knee arthroplasty (TKA). METHODS: This retrospective cohort study using 2016 to 2019 data from a 20% national sample of Medicare enrollees included patients aged 66 and over years who received an elective TKA, were discharged to home, received home health care, and had both admission and discharge assessments of pain (n = 35,186). Study outcomes were pain score difference between admission and discharge and less-than-daily pain interfering with activity at discharge. Opioid and GABA prescriptions after surgery and receipt of nerve block within 3 days of surgery were also assessed. RESULTS: There were 30% of patients who had a pain score decrease of 3 to 4 levels and 55.8% had pain score decreases of 1 to 2 levels. In multivariable analyses, receiving a nerve block was significantly associated with pain score reduction. A GABA prescription increased the magnitude of pain score reduction among those receiving a nerve block. Results from inverse probability weighted analysis with propensity score showed that coprescribing of GABA and low-dose opioid was associated with significantly lower pain scores. CONCLUSIONS: Post-TKA opioid use was not associated with pain score reduction. Receiving a nerve block was associated with a modest pain score reduction. Co-prescribing GABA with low-dose opioid or receiving a nerve block was associated with increasing magnitudes of pain reduction. Further research should identify alternatives to opioid use for managing postoperative TKA pain.

Rural racial disparities and barriers in mammography utilization among Medicare beneficiaries in Texas: A longitudinal study.

This study examined rural racial/ethnic disparities in long-term mammography screening practices among Medicare beneficiaries. A retrospective longitudinal study was conducted using 100% Texas Medicare data for women aged 65-74 who enrolled in Medicare between 2010-2013. Of the 114,939 eligible women, 21.2% of Hispanics, 33.3% of non-Hispanic Blacks (NHB), and 38.4% non-Hispanic Whites (NHW) in rural areas were regular users of mammography, compared to 33.5%, 44.9%, and 45.3% of their counterparts in urban areas, respectively. Stratification analyses showed rural Hispanics and NHB were 33% (95% CI, 25% - 40%) and 22% (95% CI, 6% - 36%) less likely to be regular users of mammography compared to their urban counterparts. Major barriers to routine mammography screening included the lack of a primary care provider, frequent hospitalization, and comorbidity. The findings of this study highlight the importance of addressing rural racial disparities in mammography utilization among older women to ensure equitable screening practices for all populations.

Inequitable access to nonpharmacologic pain treatment providers among cancer-free U.S. adults.

OBJECTIVE: Using evidence-based nonpharmacologic pain treatments may prevent opioid overuse and associated adverse outcomes. There is limited data on the impact of access-promoting social determinants of health (SDoH: education, income, transportation) on use of nonpharmacologic pain treatments. Our objective was to examine the relationship between SDoH and use of nonpharmacologic pain treatment providers. Our goal was to understand policy-actionable factors contributing to inequity in pain treatment. METHODS: Based on Andersen's Health Utilization Model, this cross-sectional analysis of 2016-2019 Medical Expenditure Panel Survey data evaluated whether use of outpatient nonpharmacologic pain treatment providers is driven by enabling (i.e., advantageous socioeconomic resources) or need (i.e., perceived disability and diagnosed disease) factors. The study sample (unweighted n = 28,188) represented a weighted N = 81,912,730 noninstitutionalized, cancer-free, U.S. adults with pain interference. The primary outcome measured use of nonpharmacologic providers relative to exclusive prescription opioid use or no treatment (i.e., neither opioids nor nonpharmacologic). To quantify equitable access, we compared the variance-between access-promoting enabling factors versus medical need factors-that explained utilization. RESULTS: Compared to enabling factors, need factors explained twice the variance predicting pain treatment utilization. Still, the adjusted odds of using nonpharmacologic providers instead of opioids alone were 39% lower among respondents identifying as Black (95% Confidence Interval [CI], 0.49-0.76) and respondents residing in the U.S. South (95% CI, 0.51-0.74). Higher education (95% CI, 1.72-2.79) and income (95% CI, 1.68-2.42) both facilitated using nonpharmacologic providers instead of opioids. CONCLUSIONS: These findings highlight the substantial influence access-promoting SDoH have on pain treatment utilization.

Signal detection of adverse events associated with gabapentinoid use for chronic pain.

INTRODUCTION: Gabapentinoids (GABA) prescribing as a potential and conceivably safer substitute for opioids has substantially increased. Understanding all potential adverse drug events (ADEs) associated with GABA will guide clinical decision-making for pain management. METHODS: A 20% sample of Medicare enrollees with new chronic pain diagnoses in 2017-2018 was selected. GABA users were those with >=30 consecutive days prescription in a year without opioid prescription. Opioid users were similarly defined. The control group used neither of these drugs. Propensity score match across three groups based on demographics and comorbidity was performed. We used proportional reporting ratio (PRR), Gamma Poisson Shrinker, and tree-based scan statistic (TBSS) to detect ADEs within 3, 6, and 12 months of follow-up. RESULTS: Immunity disorder was detected within 3 months of follow-up by PRR compared to opioid use (PRR:2.33), and by all three methods compared to controls. Complications of transplanted organs/tissues and schizophrenia spectrum/other psychotic disorders were consistently detected by PRR and TBSS within 3 months. Skin disorders were detected by TBSS; and stroke was detected by PRR within 3 months compared to opioid use (PRR:4.74). Some malignancies were detected by PRR within 12 months. Other signals detected in GABA users were neuropathy and nerve disorders. CONCLUSIONS: Our study identified expected and unexpected ADE signals in GABA users. Neurological signals likely related to indications for GABA use. Signals for immunity, mental/behavior, and skin disorders were found in the FDA adverse event reporting system database. Unexpected signals of stroke and cancer require further confirmatory analyses to verify.

Effect of statins and testosterone replacement therapy on incident cardiovascular disease among male hormone-related cancer survivors.

Purpose: Statins and testosterone replacement therapy (TTh) have been previously linked with prostate, colorectal and male breast cancer (hereinafter we will refer as hormone related cancers [HRCa]), and cardiovascular disease (CVD). However, there is a poor understanding about the combined association of statins and TTh with incident CVD among HRCa survivors and a matched cancer-free cohort. Methods: We identified 44,330 men of whom 22,165 were previously diagnosed with HRCa, and 22,165 were age-and index-matched cancer-free in SEER-Medicare 2007-2015. Pre-diagnostic prescription of statins and TTh prior to CVD development was ascertained for this analysis in the two matched cohorts. Weighted multivariable-adjusted conditional logistic regression models were used to evaluate the independent and combined associations of statins and TTh with CVD. Results: We found that use of statins (OR = 0.51, 95% CI: 0.46-0.55) and TTh (OR = 0.81, 95% CI: 0.67-0.97) were each independently inversely associated with incident CVD in the overall sample. TTh plus statins was also inversely associated with CVD. Associations were similar in the matched cancer-free cohort. Among HRCa survivors, only statins and combination of TTh plus statins (OR = 0.60, 95% CI: 0.44-0.98) were inversely associated with CVD, but the independent use of TTh was not associated with CVD. Conclusion: In general, pre-diagnostic use of statins and TTh, prior to CVD development, independently or in combination, were inversely associated with CVD in the overall, cancer-free population, and among HRCa survivors (mainly combination). Independent effects and combination of statins and TTh remained to be confirmed with specific CVD outcomes among HRCa survivors.

Outcomes of Medicare-covered diabetes self-management training for cancer survivors with diabetes.

PURPOSE: This study aimed to examine the impact of utilization of the Medicare-covered Diabetes Self-Management Training (DSMT) on the likelihood of receiving preventive care and on outcomes among cancer survivors with diabetes. METHODS: We conducted a retrospective cohort study using 1999-2019 Texas Cancer Registry-Medicare linkage data for beneficiaries diagnosed with prostate, colorectal, or breast cancer for ≥5 years. We used propensity score matching to estimate the beneficiaries' probability of receiving DSMT and matched it with non-users. The observed DSMT outcomes were hospitalization, ER visit, eye exam, HbA1c test, foot exam, nephropathy, and all-cause mortality. DSMT utilization was set at attending 1, 2, and 3 or more sessions. Conditional Cox proportional hazard regression was built to determine the association between DSMT use and each respective outcome, unadjusted and adjusted for patients' covariates. RESULTS: A total of 79,271 beneficiaries (65% had diabetes-related complications, and 41% were either prostate or breast cancer survivors) were included. We found that (1) DSMT users had more eye exams (HR=1.27), HbA1c tests (HR=1.47), foot exams (HR=1.21), and nephropathy visits (HR=1.11), and less hospitalization (HR=0.86) and overall mortality (HR=0.70) (p≤0.01 each vs. non-users); (2) among DSMT users, 56% attended one session, 24% attended 2 sessions, and 20% attended 3 or more sessions; (3) attending 2 or ≥3 DSMT sessions was associated with more eye exams (HR=1.14), HbA1c tests (HR=1.12), and foot exams (HR=1.24). CONCLUSIONS: DSMT is instrumental to preventing or delaying complications of diabetes in cancer survivors and reducing their overall mortality. The findings may inform future efforts to promote the value of DSMT for cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: Medicare-covered DSMT offers a great value to cancer survivors with diabetes.

Text messaging intervention for Pap smear uptake: a single-institution study.

Cervical cancer continues to be one of the leading causes of death among women in many parts of the world. With the increasing proliferation of mobile technology, text messaging interventions have been effective in improving Pap smear uptake in non-United States populations. This study evaluated whether text message reminders from a health system in Galveston, Texas, USA increased uptake of cervical cancer screening as compared to usual care. A single text message reminder was sent to 16,002 unique patient phone numbers using the Televox Communication Program from February 20, 2019, to April 4, 2019. The institution's population health database was subsequently used to determine if patients received cervical cancer screening (Pap smear) following the text message transmission. Patient demographics within text message and control groups were compared using Chi-square tests. Our text messaging intervention to improve Pap smear rates did not show a statistically significant difference between the intervention group receiving a text message and the control. However, there were significant interactions between text messages and age, financial class, and county (P=0.0023, 0.0299, and <0.0001, respectively). Text messaging did have a positive impact on our most vulnerable patient populations given that the text messaging intervention showed a marginally higher rate of Pap smear among Medicaid and low-income/uninsured (MLIU) patients. Text messaging interventions do have effectiveness in increasing Pap smear uptake in populations which are most impacted by health disparities.

Association Between Aspirin-Exacerbated Respiratory Disease and Atherosclerotic Cardiovascular Disease: A Retrospective Review of US Claims Data.

BACKGROUND: Aspirin-exacerbated respiratory disease (AERD) consists of chronic rhinosinusitis with nasal polyps (CRSwNP), asthma, and hypersensitivity to aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs). Asthma is associated with increased risk of atherosclerotic cardiovascular diseases (ASCVD). However, there is lack of data on association between AERD and ASCVD. OBJECTIVE: To investigate the relationship between AERD and subsequent risk of ASCVD. METHODS: An algorithm to find patients with AERD was generated and validated through chart review at our home institution. This algorithm was applied to a national insurance claims database to obtain data for a retrospective cohort study. Demographic and comorbidity data were obtained for propensity matching. Several methods of analysis were performed on the data. RESULTS: A total of 571 patients met criteria for AERD; 3909 met criteria for asthma, CRSwNP, and no allergy to aspirin or NSAIDs (group 1); and 75,050 met criteria for asthma, CRS without nasal polyps, and no allergy to aspirin or NSAIDs (group 2). After covariate adjustment, AERD was significantly associated with ASCVD, including severe ASCVD, over groups 1 and 2 regardless of asthma severity. CONCLUSION: Patients with AERD are at higher risk of ASCVD than patients with asthma and CRSwNP or CRS without nasal polyps, underscoring the need for early ASCVD screening and a consideration for aspirin desensitization or use of a nonaspirin antiplatelet agent in the setting of AERD and comorbid ASCVD.

Utilization of diabetes self-management program among breast, prostate, and colorectal cancer survivors: Using 2006-2019 Texas Medicare data.

BACKGROUND: Cancer treatment is associated with inferior health outcomes such as diabetes. Medicare provides Diabetes Self-Management Training (DSMT) program to beneficiaries to achieve normal metabolic control and reduce the risk of micro and macro-vascular complications. This study aimed to examine the trend of DSMT utilization among cancer survivors and assess individual characteristics associated with it. METHODS: The data for this study was from Texas Cancer Registry-Medicare linkage data of patients with prostate, breast, or colorectal cancer diagnosed in 1999-2017. Outcome variables include the number of first-time DSMT users, the number of total users, and the average number of DSMT utilization in minutes. We performed logistic regression and gamma regression to obtain a multivariable-adjusted odds ratio for the association between DSMT utilization and individual characteristics. RESULTS: The number of first-time users has slowly increased over the years (from 99 to 769 per 1,000) but suddenly dropped after 2016. The number of all users (first-time and follow-up users) has increased (from 123 to 1,201 per 1,000) and plateaued after 2016. Determinants including Hispanic ethnicity (O.R. = 1.10) and Medicare-Medicaid dual eligibility (O.R. = 1.25) are positively associated with both the initiation and retention of the DSMT. A barrier to both initiation and retention of DSMT is living in a metropolitan area (O.R. = 0.90). CONCLUSIONS: Multi-level strategies to enhance accessibility and availability of DSMT programs for Medicare beneficiaries are highly recommended. Examining the determinants of initiation and retention of DSMT over 14 years provides insights on strategies to meet the needs of cancer survivors and reduce the burden of diabetes on them.

Radiological-histopathological discordance in patients transplanted for HCC and its impact on post-transplant outcomes.

BACKGROUND AND AIMS: Contrast-enhanced cross-sectional imaging is the cornerstone in the diagnosis, staging, and management of HCC, including eligibility for liver transplantation (LT). Radiological-histopathological discordance may lead to improper staging and may impact patient outcomes. We aimed to assess the radiological-histopathological discordance at the time of LT in HCC patients and its impact on the post-LT outcomes. METHODS: We analyzed further the effect of 6-month waiting policy on the discordance. Using United Network for Organ Sharing-Organ Procurement and Transplantation Network (UNOS-OPTN) database, we examined the discordance between pre-LT imaging and explant histopathology for all adult HCC patients who received liver transplants from deceased donors between April 2012 and December 2017. Kaplan-Meier methods and Cox regression analyses were used to evaluate the impact of discordance on 3-year HCC recurrence and mortality. RESULTS: Of 6842 patients included in the study, 66.7% were within Milan criteria on both imaging and explant histopathology, and 33.3% were within the Milan based on imaging but extended beyond Milan on explant histopathology. Male gender, increasing numbers of tumors, bilobar distribution, larger tumor size, and increasing AFP are associated with increased discordance. Post-LT HCC recurrence and death were significantly higher in patients who were discordant, with histopathology beyond Milan (adj HR 1.86, 95% CI 1.32-2.63 for mortality and 1.32, 95% CI 1.03-1.70 for recurrence). Graft allocation policy with 6-month waiting time led to increased discordance (OR 1.19, CI 1.01-1.41), although it did not impact post-LT outcome. CONCLUSION: Current practice for staging of HCC based on radiological imaging features alone results in underestimation of HCC burden in one out of three patients with HCC. This discordance is associated with a higher risk of post-LT HCC recurrence and mortality. These patients will need enhanced surveillance to optimize patient selection and aggressive LRT to reduce post-LT recurrence and increase survival.
