Patients characteristics related to screening mammography cancellation and rescheduling rates during the COVID-19 pandemic

Breast Imaging Patient Demographics at a Major Comprehensive Cancer Center Before and During the COVID-19 Pandemic

OBJECTIVE

The coronavirus disease of 2019 (COVID-19) pandemic disproportionately affected certain vulnerable communities. The purpose of our study was to determine how COVID-19 affected the socioeconomic demographics of breast imaging patients at a major comprehensive cancer center.

METHODS

This retrospective cohort study compared female patients who underwent screening mammograms, diagnostic mammograms, breast ultrasound, or breast MRI during the following time periods: prepandemic (February 1, 2018, through February 29, 2020), acute pandemic (March 1, 2020, through June 30, 2020), subacute pandemic (August 1, 2020, through December 31, 2020), and chronic pandemic (January 1, 2021, through June 30, 2022). Statistics were performed using the generalized estimating equations approach.

RESULTS

A total of 74,398 female patients (mean age, 55.6 ± 12.4 years) underwent 238,776 total breast imaging examinations. For screening mammograms, Hispanics represented 27.1% (9,197 of 33,960) of patients in the prepandemic time period compared with 16.7% (604 of 3,621) in the acute pandemic time period, 18.7% (1,835 of 9,830) in the subacute pandemic time period, and 24.3% (7,492 of 30,869) in the chronic pandemic time period (all P < .0001). Self-pay patients saw similar declines for screening mammograms during the same time periods: 21.7% (7,375 of 33,960), 7.9% (286 of 3,621), 9.5% (933 of 9,830), and 17.4% (5,357 of 30,869), respectively (all P < .0001, compared with the prepandemic time period). Similarly dramatic trends were not observed for race or other imaging examinations.

DISCUSSION

At our cancer center, Hispanics and self-pay patients were disproportionately affected by the COVID-19 pandemic. Strategies to improve health inequities are needed.

COVID-19 pandemic impact on the potential exacerbation of screening mammography disparities: A population-based study in Ontario, Canada

Strategies to ramp up breast cancer screening after COVID-19 require data on the influence of the pandemic on groups of women with historically low screening uptake. Using data from Ontario, Canada, our objectives were to 1) quantify the overall pandemic impact on weekly bilateral screening mammography rates (per 100,000) of average-risk women aged 50-74 and 2) examine if COVID-19 has shifted any mammography inequalities according to age, immigration status, rurality, and access to material resources. Using a segmented negative binomial regression model, we estimated the mean change in rate at the start of the pandemic (the week of March 15, 2020) and changes in weekly trend of rates during the pandemic period (March 15-December 26, 2020) compared to the pre-pandemic period (January 3, 2016-March 14, 2020) for all women and for each subgroup. A 3-way interaction term (COVID-19*week*subgroup variable) was added to the model to detect any pandemic impact on screening disparities. Of the 3,481,283 mammograms, 8.6 % (n = 300,064) occurred during the pandemic period. Overall, the mean weekly rate dropped by 93.4 % (95 % CI 91.7 % - 94.8 %) at the beginning of COVID-19, followed by a weekly increase of 8.4 % (95 % CI 7.4 % - 9.4 %) until December 26, 2020. The pandemic did not shift any disparities (all interactions p > 0.05) and that women who were under 60 or over 70, immigrants, or with a limited access to material resources had persistently low screening rate in both periods. Interventions should proactively target these underserved populations with the goals of reducing advanced-stage breast cancer presentations and mortality.

A rapid review of COVID-19's global impact on breast cancer screening participation rates and volumes from January to December 2020

COVID-19 has strained population breast mammography screening programs that aim to diagnose and treat breast cancers earlier. As the pandemic has affected countries differently, we aimed to quantify changes in breast screening volume and uptake during the first year of COVID-19 . We systematically searched Medline, the World Health Organization (WHO) COVID-19 database, and governmental databases. Studies covering January 2020 to March 2022 were included. We extracted and analyzed data regarding study methodology, screening volume, and uptake. To assess for risk of bias, we used the Joanna Briggs Institute (JBI) Critical Appraisal Tool. Twenty-six cross-sectional descriptive studies (focusing on 13 countries/nations) were included out of 935 independent records. Reductions in screening volume and uptake rates were observed among eight countries. Changes in screening participation volume in five nations with national population-based screening ranged from -13 to -31%. Among two countries with limited population-based programs, the decline ranged from -61 to -41%. Within the USA, population participation volumes varied ranging from +18 to -39%, with suggestion of differences by insurance status (HMO, Medicare, and low-income programs). Almost all studies had high risk of bias due to insufficient statistical analysis and confounding factors. The extent of COVID-19-induced reduction in breast screening participation volume differed by region and data suggested potential differences by healthcare setting (e.g., national health insurance vs. private healthcare). Recovery efforts should monitor access to screening and early diagnosis to determine whether prevention services need strengthening to increase the coverage of disadvantaged groups and reduce disparities.

Breast cancer care amidst a pandemic: a scoping review to understand the impact of coronavirus disease 2019 on health services and health outcomes

Since the onset of the coronavirus disease 2019 (COVID-19) pandemic, health services for breast cancer (BC) have been disrupted. Our scoping review examines the impact of the COVID-19 pandemic on BC services, health outcomes, and well-being for women. Additionally, this review identifies social inequalities specific to BC during the pandemic. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews guidelines, the literature search was conducted using scientific databases starting from March 2020 through November 2021. Studies were identified and selected by two researchers based on inclusion criteria, and the relevant data were extracted and charted to summarize the findings. Ninety-three articles were included in this review. Main themes included are as follows: (i) the impact of COVID-19 on BC services; (ii) the impact of COVID-19 on health outcomes and well-being in women with BC; and (iii) any variation in the impact of COVID-19 on BC by social determinants of health. There were apparent disruptions to BC services across the cancer continuum, especially screening services. Clinical repercussions were a result of such disruptions, and women with BC experienced worsened quality of life and psychosocial well-being. Finally, there were social inequalities dependent on social determinants of health such as age, race, insurance status, and region. Due to the disruption of BC services during the COVID-19 pandemic, women were impacted on their health and overall well-being. The variation in impact demonstrates how health inequities have been exacerbated during the pandemic. This comprehensive review will inform timely health-care changes to minimize long-term impacts of the pandemic and improve evidence-based multidisciplinary needs.

Experience of a single healthcare system with screening mammography before and after COVID-19 shutdown

PURPOSE

To evaluate COVID-19's longitudinal impact on screening mammography volume trends.

METHODS

HIPAA-compliant, IRB-approved, single institution, retrospective study of screening mammogram volumes before (10/21/2016-3/16/2020) and greater than two years after (6/17/2020-11/30/2022) a state-mandated COVID-19 shutdown (3/17/2020-6/16/2020) were reviewed. A segmented quasi-poisson linear regression model adjusting for seasonality and network and regional population growth compared volume trends before and after the shutdown of each variable: age, race, language, financial source, risk factor for severe COVID-19, and examination location.

RESULTS

Adjusted model demonstrated an overall increase of 65 screening mammograms per month before versus a persistent decrease of 5 mammograms per month for >2 years after the shutdown (p < 0.0001). In subgroup analysis, downward volume trends were noted in all age groups <70 years (age < 50: +9/month before vs. -7/month after shutdown; age 50-60: +17 vs. -7; and age 60-70: +21 vs. -2; all p < 0.001), those identifying as White (+55 vs. -8, p < 0.0001) and Black (+4 vs. +1, p = 0.009), all financial sources (Medicare: +22 vs. -3, p < 0.0001; Medicaid: +5 vs. +2, p = 0.006; private insurance/self-pay: +38 vs. -4, p < 0.0001), women with at least one risk factor for severe COVID-19 (+30 vs. -48, p < 0.0001), and screening mammograms performed at a hospital-based location (+48 vs. -14, p = 0.0001).

CONCLUSION

The screening mammogram volume trend more than two years after the COVID-19 shutdown has continued to decline for most patient populations. Findings highlight the need to identify additional areas for education and outreach.

Breast cancer screening during the COVID-19 pandemic: moving from disparities to health equity

The COVID-19 pandemic created unprecedented disruptions to routine health care in the United States. Screening mammography, a cornerstone of breast cancer control and prevention, was completely halted in the spring of 2020, and screening programs have continued to face challenges with subsequent COVID-19 waves. Although screening mammography rates decreased for all women during the pandemic, a number of studies have now clearly documented that reductions in screening have been greater for some populations than others. Specifically, minoritized women have been screened at lower rates than White women across studies, although the specific patterns of disparity vary depending on the populations and communities studied. We posit that these disparities are likely due to a variety of structural and contextual factors, including the differential impact of COVID-19 on communities. We also outline key considerations for closing gaps in screening mammography. First, practices, health systems, and communities must measure screening mammography use to identify whether gaps exist and which populations are most affected. Second, we propose that strategies to close disparities in breast cancer screening must be multifaceted, targeting the health system or practice, but also structural factors at the policy level. Health disparities arise from a complex set of conditions, and multimodal solutions that address the complex, multifactorial conditions that lead to disparities may be more likely to succeed and are necessary for promoting health equity.

A systematic review of the impact of the COVID-19 pandemic on breast cancer screening and diagnosis

BACKGROUND

Breast cancer care has been affected by the COVID-19 pandemic. This systematic review aims to describe the observed pandemic-related changes in clinical and health services outcomes for breast screening and diagnosis.

METHODS

Seven databases (January 2020-March 2021) were searched to identify studies of breast cancer screening or diagnosis that reported observed outcomes before and related to the pandemic. Findings were presented using a descriptive and narrative approach.

RESULTS

Seventy-four studies were included in this systematic review; all compared periods before and after (or fluctuations during) the pandemic. None were assessed as being at low risk of bias. A reduction in screening volumes during the pandemic was found with over half of studies reporting reductions of ≥49%. A majority (66%) of studies reported reductions of ≥25% in the number of breast cancer diagnoses, and there was a higher proportion of symptomatic than screen-detected cancers. The distribution of cancer stage at diagnosis during the pandemic showed lower proportions of early-stage (stage 0-1/I-II, or Tis and T1) and higher proportions of relatively more advanced cases than that in the pre-pandemic period, however population rates were generally not reported.

CONCLUSIONS

Evidence of substantial reductions in screening volume and number of diagnosed breast cancers, and higher proportions of advanced stage cancer at diagnosis were found during the pandemic. However, these findings reflect short term outcomes, and higher-quality research examining the long-term impact of the pandemic is needed.

Addressing Disparities Related to Access of Multimodality Breast Imaging Services Before and During the COVID-19 Pandemic

Despite technological advancements focused on reducing breast cancer mortality through early detection, there have been reported disparities in the access to these imaging services with underserved patient populations (including racial minority groups and patients of low socioeconomic status) showing underutilization compared to other patient groups. These underserved populations tend to have more advanced breast cancer presentations, in part due to delays in diagnosis resulting in later stage of disease presentation. To make matters worse, the COVID-19 pandemic declared in March 2020 has resulted in significant healthcare disruptions leading to extensive delays in breast imaging services which are expected to negatively impact breast cancer mortality long-term. Given the worsening disparity in breast cancer mortality among racial/ethnic minorities and financially disadvantaged groups, it is vital to address these disparity gaps with the goal of reducing the barriers to timely breast cancer diagnosis and addressing breast cancer mortality differences among breast cancer patients. Therefore, this review aims to provide a discussion highlighting the disparities related to breast imaging access, the effects of the COVID-19 pandemic on these disparities, current targeted interventions implemented in breast imaging practices to reduce these disparities, and future directions on the journey to reducing disparity gaps for breast imaging patients. Tackling the root cause factors of the persistent breast cancer-related disparities is critical to meeting the needs of patients who are disadvantaged and can lead to continued improvement in the quality of individualized care for patients who have higher breast cancer morbidity and mortality risks.

A national quality improvement study identifying and addressing cancer screening deficits due to the COVID-19 pandemic

BACKGROUND

Cancer-related deaths over the next decade are expected to increase due to cancer screening deficits associated with the coronavirus disease 2019 (COVID-19) pandemic. Although national deficits have been quantified, a structured response to identifying and addressing local deficits has not been widely available. The objectives of this report are to share preliminary data on monthly screening deficits in breast, colorectal, lung, and cervical cancers across diverse settings and to provide online materials from a national quality improvement (QI) study to help other institutions to address local screening deficits.

METHODS

This prospective, national QI study on Return-to-Screening enrolled 748 accredited cancer programs in the United States from April through June 2021. Local prepandemic and pandemic monthly screening test volumes (MTVs) were used to calculate the relative percent change in MTV to describe the monthly screening gap.

RESULTS

The majority of facilities reported monthly screening deficits (colorectal cancer, 80.6% [n = 104/129]; cervical cancer, 69.0% [n = 20/29]; breast cancer, 55.3% [n = 241/436]; lung cancer, 44.6% [n = 98/220]). Overall, the median relative percent change in MTV ranged from -17.7% for colorectal cancer (interquartile range [IQR], -33.6% to -2.8%), -6.8% for cervical cancer (IQR, -29.4% to 1.7%), -1.6% for breast cancer (IQR, -9.6% to 7.0%), and 1.2% for lung cancer (IQR, -16.9% to 19.0%). Geographic differences were not observed. There were statistically significant differences in the percent change in MTV between institution types for colorectal cancer screening (P = .02).

CONCLUSION

Cancer screening is still in need of urgent attention, and the screening resources made available online may help facilities to close critical gaps and address screenings missed in 2020.

LAY SUMMARY

Question: How can the effects of the coronavirus disease 2019 pandemic on cancer screening be mitigated?

FINDINGS

When national resources were provided, including methods to calculate local screening deficits, 748 cancer programs promptly enrolled in a national Return-to-Screening study, and the majority identified local screening deficits, most notably in colorectal cancer. Using these results, 814 quality improvement projects were initiated with the potential to add 70,000 screening tests in 2021. Meaning: Cancer screening is still in need of urgent attention, and the online resources that we provide may help to close critical screening deficits.

Mobile Mammography Services and Underserved Women

Breast cancer, the second most common cause of cancer in women, affects people across different ages, ethnicities, and incomes. However, while all women have some risk of breast cancer, studies have found that some populations are more vulnerable to poor breast cancer outcomes. Specifically, women with lower socioeconomic status and of Black and Hispanic ethnicity have been found to have more advanced stages of cancer upon diagnosis. These findings correlate with studies that have found decreased use of screening mammography services in these underserved populations. To alleviate these healthcare disparities, mobile mammography units are well positioned to provide convenient screening services to enable earlier detection of breast cancer. Mobile mammography services have been operating since the 1970s, and, in the current pandemic, they may be extremely helpful. The COVID-19 pandemic has significantly disrupted necessary screening services, and reinstatement and implementation of accessible mobile screenings may help to alleviate the impact of missed screenings. This review discusses the history and benefits of mobile mammography, especially for underserved women.

Rationing and Disparities in Health Care: Implications for Radiology Clinical Practice Guidelines

We examine the relationship between the rationing of health care resources and disparities in health care delivery and the specific implications for radiologic resource allocation frameworks such as the ACR Appropriateness Criteria. We explore what rationing is in this context and how it is manifested in radiology. We review how rationing has taken many forms and how rationing has influenced the development of disparities in access and outcomes within health care and specifically within the context of radiology. We describe how the relationship between rationing and health care delivery disparities manifested during the coronavirus disease 2019 pandemic and the corrective measures that were proposed to established rationing frameworks to facilitate more equitable pandemic-related resource distribution. We offer suggestions regarding how such solutions might be brought into radiologic resource allocation schemes to help mitigate disparities in radiologic care in the future.
