Abstract
Background Breast cancer, the second leading cause of cancer-related deaths in women in the USA, is effectively treated through early detection and screening. This quality improvement (QI) project aimed to improve mammography screening rates from the baseline of 50% to 60% within 12 months for patients aged 50–74 years at an Internal Medicine Clinic.
Methods We used the Plan, Do, Study, Act (PDSA) model. A multidisciplinary team used a fishbone diagram to identify barriers to suboptimal screening. The QI team created a driver diagram and process flow map. The mammogram screening rate was the outcome measure. Mammogram order and completion rates were the process measures. We implemented six PDSA cycles. Major interventions included the use of a nurse navigator, enhancements in health information technology, and education to patients, providers, and nursing staff. Mammograms were offered in a mobile bus, located in the hospital campus and in under-resourced inner-city neighbourhoods to improve the access. Data analysis was performed using monthly statistical process control charts.
Results The project exceeded its initial goal, achieving a breast cancer screening rate of 66% (n=490 of 744) during the study period and was sustainable at 69%, 3 months post-project. The mammogram order rate was 58% (n=432 of 744) and completion rate was 53% (n=231 of 432) within 12 months.
Conclusions We attributed the success of this QI project to the education of patients, nurses and physicians, the use of a nurse navigator and engagement of a multidisciplinary team. Access to mobile mammography bus addressed the social determinants of health barriers in a marginalised population.

Introduction
Background
Breast cancer is the most common non-skin cancer and the second leading cause of cancer-related deaths in women in the USA.1 Early detection from screening has contributed to an increase in overall survival rates.2 However, it is important to address the disparities in breast cancer outcomes among different racial and ethnic groups. African American women face significant challenges in relation to breast cancer. African American women experience the highest breast cancer mortality rate among all racial or ethnic groups in the USA, with a 40% mortality rate.3 4 When compared with their white counterparts, the mortality rate for black women diagnosed with breast cancer is 42% higher.1 4 Furthermore, among women under the age of 40 years, African American women have a higher incidence of breast cancer compared with white women.1 Several factors contribute to the higher mortality rates observed among African American women. These factors are multifactorial and may include later-stage diagnosis, socioeconomic disparities, differences in access to healthcare and biological differences in breast cancer subtype response.1 3 Addressing these disparities requires a multifaceted approach that includes improving access to healthcare services, promoting early detection through education and screening initiatives, and addressing socioeconomic barriers.
The US Preventive Services Task Force (USPSTF)5 recommends biennial mammography screening for women aged 50–74 years. The 2016 USPSTF guidelines are recommended for women aged 40–49 years; the USPSTF acknowledges the potential benefits and harms of mammography screening, emphasising the importance of individual decision-making based on personal values, risk factors and preferences. The USPSTF suggests that women in this age group engage in a discussion with their healthcare providers to make an informed decision.
Problem description
In a safety-net hospital-based Internal Medicine Clinic (IMC), 75% of the patient population is composed of African Americans. We discovered a significant healthcare disparity in breast cancer screening. Our baseline screening rate stood at 50%, which fell below the average rates observed in the USA.6 The national average of the proportion of women aged 40 years and older who reported undergoing a mammogram in the past 2 years remained consistent, starting at 67.1% in 2008 and slightly declining to 65.6% in 2018. However, in 2019, there was an increase to 67.5% in this group who had received a mammogram within the previous 2 years.6–8 This quality improvement (QI) project was aligned with the organisation’s highest priority and received enormous support from administrative leadership. The objective of this QI project was to enhance breast cancer screening rates from the baseline of 50% to 60% in an academic IMC within 12 months, specifically targeting patients aged 50–74 years, based on guidelines provided by USPSTF. Our target goal of 60% from a 50% baseline rates within 1 year was set because this QI project was conducted in a safety-net clinic in an under-resourced patient population who faced various barriers to social determinants of health. We anticipated many challenges to optimise breast cancer screening rates in this unique patient population; therefore, we selected a 10% improvement within 1 year from the baseline rate. Our aim statement was achievable and realistic based on ‘SMART’ goals9 and based on previous QI projects from this clinic.10–16
Methods
Setting
This QI study was conducted at an academic IMC situated within a tertiary care safety-net hospital in Western New York. The IMC primarily serves an urban population that is predominantly under-resourced and consists of mostly African Americans (75.0%). Patients use the IMC for longitudinal primary care, with an average of 800 monthly visits. The IMC is staffed by a diverse healthcare team, including 35 residents from the University at Buffalo’s Internal Medicine Residency Program and 4 attending physicians. The clinic’s electronic health record (EHR) system did not possess the capability for medical decision support tools or chart alerts, which could aid in clinical decision-making and reminders for the physicians.
Design
This QI initiative was structured using the Plan, Do, Study, Act (PDSA) model, a widely recognised framework for healthcare improvement.9 17 Additionally, we incorporated the Institute of Medicine’s STEEEP model, which outlines six aims for transforming the healthcare system: Safe, Timely, Effective, Efficient, Equitable and Patient-Centered into planning, implementing and assessing PDSA cycles18 (table 1A). The multidisciplinary QI team comprised of attending physicians, resident physicians, nursing and ancillary staff, patients, a social worker, a case manager, radiologist, the manager from the mobile mammography bus, hospital leadership and information technology staff. Stakeholders’ mapping strategy of Mendelow’s matrix was used based on the level of interest and level of influence to engage stakeholders (figure 1A). We used the Standards for Quality Improvement Reporting Excellence 2.0 guidelines for reporting this QI project.19 The QI team performed a root cause analysis using a fishbone diagram and identified barriers to optimal breast cancer screening (figure 1B). The significant barriers included: provider and patient knowledge gap, lack of interface with EHR and access to mammogram. We developed a process flow map to optimise opportunities to improve screening mammography (figure 1C). The QI team created a driver diagram by identifying primary and secondary drivers, and prioritising change ideas to overcome the challenges to accomplish our aim (figure 2A).
This study included women between the ages of 50 and 74 years, evaluated in the clinic from 1 September, 2018 to 30 August, 2019 and excluded patients who required diagnostic mammography. The hospital offered regular mammography in a mobile bus, available in the hospital campus and in under-resourced inner-city neighbourhoods to improve the access. The majority of mammography was performed in the mobile bus. Patients with mobility issue preferred to obtain mammography in an outside facility. Physicians discussed breast cancer screening with average-risk patients and engaged patients in shared decision-making process. Shared decision-making involves explaining all treatment options to the patient and coming to a joint decision that respects the patient’s values.20 Physicians ordered screening mammogram based on patients’ preference and value. Physicians referred high-risk women to an oncology clinic for genetic counselling and further evaluation. This study is based on USPSTF guidelines for breast cancer screening.5
Measurements
An electronic patient registry for eligible patients for breast cancer screening based on (USPSTF) guidelines was created prior to this QI and was readily available. Retrospective examination of the population health registry for eligible patients seen within the past 18 months in IMC revealed a baseline breast cancer screening rate of less than 50%. Percentage of baseline screening rate was calculated from total eligible patients between the ages 50 and 74 years, seen in the clinic 18 months prior to the start of the QI project; numerator was total eligible patients minus patients who had not completed screening mammogram (due or overdue) and denominator was total eligible patients during 18 months. A statistical process control chart was not used to calculate the baseline screening rate. The outcome measure for this study focused on mammogram screening rates, indicating the percentage of eligible patients who underwent mammography. Mammogram order rates and completion rates served as the process measures, reflecting the frequency of ordering mammograms and the proportion of ordered mammograms that were successfully completed. As part of assessing the impact of the QI initiative, the team also considered the potential effects on patient wait times in the clinic and the level of job satisfaction among nursing staff and providers, which served as balance measures. To measure patient wait times for the primary care clinic appointment, the QI team defined the average wait time as the duration patients spent in the examination room for nursing and physicians’ assessment. It was anticipated that the provision of education on breast cancer screening to patients would require additional time, potentially resulting in increased wait times.
Strategy
We have outlined specific steps of ‘Plan (Predict), Do, Study and Act’ phases in various PDSA cycles (table 1B: PDSA cycle 1 and 1c, PDSA cycles 2–6). We incorporated reflection and feedback of stakeholder in the assessment/study phase of each PDSA cycle (table 1B,C).21
PDSA cycle 1 (September 2018): optimisation of EHR and patient navigator
Physician leaders collaborated with information technology staff for enhancements in EHR for this QI project. The innovative changes in EHR are summarised in table 1B.
PDSA cycle 1a: provider reminder
The QI team created a template for new nursing workflow to alert physicians to review breast cancer screening. Two questions were inserted into the History of Presenting Illness section of the clinic visit note: (1) Did you have mammogram this year? and (2) Are you willing to discuss breast cancer screening with your physicians today? The nursing staff completed this tool in the EHR during the patient check-in process before the physician–patient encounter. In the clinic EHR, there was clinic workflow for documenting refusal of mammogram as structured data to capture this information in electronic patient registry. There was a poor compliance from the provider for this workflow as it required a manual entry in EHR and providers were not able to document structured data due to time constraints during clinic visits, but it was mentioned in the provider clinic note as unstructured data.
PDSA cycle 1b: capturing results
The QI team collaborated with information technology staff and developed an interface of mammography results in real time from the mammography mobile bus for review by the attending physician. The medical office assistant scanned and completed the report to capture mammography completion as a structured data in EHR. This step was crucial to ensure the accuracy of electronic patient registry.
PDSA cycle 1c: standing orders for mammogram
The patient navigator and medical office assistant had the ability to generate standing orders for a screening mammography.
PDSA cycle 1d: patient navigator
The QI team appointed a nurse as the patient navigator to educate and counsel patients about breast cancer screening. The patient navigator was given access to order, schedule and reschedule mammography. The patient navigator was provided an open-access calendar from the mammography mobile bus to schedule appointments for those seen in the clinic and those lost to follow-up in the clinic but were overdue for screening. The newly created EHR workflow and the use of patient navigator continued during the study period, beyond this PDSA cycle.
PDSA cycle 2 (October–November 2018): physician and staff education
Resident team leaders identified a gap in residents’ knowledge of the USPSTF breast cancer screening guidelines. Team leaders educated physicians and clinic staff through PowerPoint presentations in a small group discussion setting. The resident team leaders focused the training on USPSTF breast cancer screening guidelines, modifiable risk factors for breast cancer including smoking cession, limiting alcohol intake, exercising and maintaining healthy weight and healthy diet. Redesign of EHR and nursing workflow were also reviewed. Pre-test and post-test assessments comprised of 5 multiple choice questions were conducted to evaluate objective improvement in the residents’ knowledge (table 1C).
PDSA cycle 3 (December 2018–January 2019): patient education and engagement
The nursing staff provided pamphlets and booklets about breast cancer screening to patients during their clinic visits. The hospital sponsored free raffle tickets for attendance to a National Football League Buffalo Bills game once patients completed mammogram screening. This incentive was offered for 1 month to complete the screening when they were due or overdue for mammography (table 1C).
PDSA cycle 4 (February–March 2019): feedback to stakeholders
The lead physician shared reports every 5 weeks with the resident physicians and nursing staff.
PDSA cycle 5 (April–May 2019): close loops for referrals and tests
Our specific steps to close loops for referrals and tests are summarised in the process flow map (figure 2B). The patient navigator nurse tracked completion of mammograms and rescheduled mammography when a patient missed their appointment. An appointment was offered that was at a convenient location to the patient near home or work, or in hospital campus. Free transportation was offered to the patients with assistance from a social worker when needed. The QI team improved care coordination and communication between clinic staff and staff from the mammography bus to increase scheduling and completion of mammogram. The patient navigator reviewed a list of due/overdue mammogram orders and called patients to schedule. The patient navigator and nursing staff printed a mammogram report from HEALTHeLINK (a digital clinical database from hospitals, physicians, health plans and other healthcare providers in the eight counties of Western New York state), when the report was not in the clinic EHR. This report was scanned and sent to physicians for a review. The nursing staff also called outside facilities to track reports of completed mammography. The team designed a clinic protocol for timely review of mammography results to address abnormal results. Normal results were scanned in the EHR and/or received electronically in the physician’s task box. Physicians were trained to verify a mammography report within 48 hours. Abnormal mammography reports were received by fax or by verbal report on the phone. Physicians addressed abnormal mammography results the same day. Physicians notified patients in a timely manner of abnormal mammograms, ordered diagnostic imaging as needed and referral to breast surgeon for further evaluation (table 1C).
PDSA cycle 6 (June–August 2019): refresher training to residents and nursing staff
Resident team leaders conducted training for new interns and refresher training for resident physicians and nursing staff. The redesigned clinic workflow for ordering and completing mammography was also reinforced in the training (table 1C).
Data analysis
We used QI macros software to plot monthly statistical process control p-charts.
Results
Demographics
The majority of patients were African Americans (73.5%) with the remainder of the patients being white (20.9%) or other races (5.6%), and 55.0% had body mass index ≥30 or more. The mean age was 61.6 years (SD=6.4).
Process measures
Mammogram order rate
During the 1-year study period, we achieved a mammogram order rate of 58% (n=432 of 744). During the project and 3 months after the project period, we achieved a mean order rate of 61% (figure 3A).
Mammogram completion rate
During the 1-year project period, we achieved mammogram completion rate of 53% (n=231 of 432). During the project and after the project period, we achieved a mean completion rate of 41% (figure 3B).
Outcome measures
Breast cancer screening rates
During the 1-year project period, we achieved a mammogram average screening rate of 66% (n=490 of 744). During the various PDSA cycles, we achieved a variable and sustainable increase in mammogram screening rates. During the project and 3 months after the project period, we achieved a mean screening rate of 69% (figure 4).
Balance measures
Increase in wait time
Prior to the implementation of this QI project, the average time spent in the clinic during a follow-up visit was approximately 1 hour. Throughout the course of the project, this time frame remained consistent and did not change significantly. These findings suggest that the implementation of shared decision-making and discussions did not result in noticeable delays or prolonged wait times for patients attending the clinic.
Nurse and physician satisfaction
Physicians reported overall satisfaction and did not feel constrained by time during clinic visits. Similarly, the nursing staff expressed satisfaction with the project and did not report any significant increase in the workload. These observations were gathered through informal feedback and reflection sessions, where anecdotal reports were shared and discussed.
Discussion
This QI study aimed to improve breast cancer screening rates in an academic IMC, specifically targeting the identified gap in screening in a marginalised population. The study used a multifaceted approach to address barriers and enhance screening rates. The interventions included improving access to screening services, providing education to patients and healthcare providers, and leveraging innovative technologies for a streamlined screening process. The study aimed to reduce disparities in screening, particularly among under-resourced populations. By implementing these strategies in the IMC, the goal was to positively impact screening rates, promote early detection and improve treatment outcomes for at-risk women. We exceeded our goal and achieved 66% breast cancer screening rates within 12 months and continued to sustain it during the 3-month period post-project at 69%. We observed a gradual, sustainable increase in mammography completion rates after initial decline during October 2018 (PDSA cycle 2). Decrease in mammogram completion rates may be related to an initial increase in mammogram orders resulting in an increase in workload for the patient navigator to assist with scheduling and tracking completion of mammography. In addition, providers may have ordered mammography during patient visits in October 2018, regardless of the exact month of the patient’s actual due date for biennial mammography. Mammography was not scheduled until it was exactly 2 years from the patient’s last mammogram date due to insurance regulation; therefore, it may be completed at a later date. We observed variability and decrease in mammogram screening rates during December 2018, March–April 2019 and July 2019. This may be due to the holidays and weather during the winter months. Additionally, a decrease in order rates may be due to new resident physicians in July 2019 at the start of a new academic year and other providers’ related barriers.
Numerous studies have demonstrated the effectiveness of patient navigation programmes in improving breast cancer screening rates, reducing disparities and enhancing patient satisfaction.22–26 These programmes have been particularly successful in reaching under-resourced populations and improving access to screening services. Patient navigators play a crucial role in educating individuals about the importance of breast cancer screening and addressing any concerns or misconceptions they may have. Patient navigators provide assistance with appointment scheduling, transportation arrangements, language interpretation and addressing financial concerns. Patient navigators facilitate communication between patients and healthcare providers, ensuring that patients receive appropriate follow-up care and timely interventions if abnormalities are detected during screening.26 In 2014, a patient navigation model was implemented to improve breast and cervical cancer screening among homeless women in five shelters and shelter clinics in New York City. The patient navigation approach included opt-out screening, cancer health and screening education, scheduling and follow-up for screening completion, result communication to patients and providers, and care coordination with social services organisations. The findings suggest that patient navigation programmes can help improve screening rates in vulnerable populations.27 The current study used a patient/nurse navigator who collaborated with patients to create a simplified patient education pamphlet, incorporating their valuable feedback. Through this process, patients were able to identify barriers to screening mammograms. The study identified two significant barriers: knowledge gaps leading to a lack of interest and limited access to transportation. These findings highlight the importance of addressing patient education needs and providing transportation support to overcome barriers and increase the completion of mammograms for breast cancer screening. Patients played an active role in this QI project, engaging in shared decision-making with their physicians regarding breast cancer screening.
Implementing appointment reminder systems through phone calls, text messages or email notifications can help patients stay informed and ensure they do not miss their scheduled screening.28 29 Ahmed et al conducted a study that demonstrated the effectiveness of a stepwise intervention approach in improving mammography rates among hard-to-reach, low-income, insured women.30 The study found that a prompt letter from the primary care physician and counselling from lay health workers significantly increased the likelihood of breast cancer screening by 80%. These findings highlight the importance of implementing comprehensive interventions to overcome barriers and improve mammography rates in under-resourced populations. This study focused on using phone call communications by patient navigator and an automated call from the mobile mammography bus as a reminder.
Previous studies have explored the use of mobile mammography for early screening and detection of breast cancer. They enhance accessibility to breast cancer screening services by reaching under-resourced populations, including rural areas and urban communities with limited access to healthcare. This increased accessibility contributes to higher screening rates and early detection of breast cancer. Mobile mammography units help reduce patient travel and wait times, making screening more convenient for individuals.31 32 This study enhanced patients’ access to mobile mammography at various locations within under-resourced communities and in the hospital campus.
Providing financial rewards or reimbursements to patients who complete recommended breast cancer screening has shown promising results in improving screening rates. These incentives can include gift cards, cash rewards or reductions in healthcare costs associated with screening.33 This study included a financial incentive, the hospital-sponsored free raffle tickets for attendance to a National Football League Buffalo Bills game once patients completed mammogram screening. This incentive was offered to complete the screening when they were due or overdue for mammography. Offering patient incentive is not feasible and sustainable in a safety-net clinic with limited resources.
Lessons learnt
The team discovered that the most effective approach to assessing breast cancer screening was to seize every opportunity during any patient encounter, regardless of the type of visit, rather than deferring it to a later date specifically for an annual wellness visit. During the prestudy period, patients were instructed to call the mammography mobile bus and schedule an appointment after a physician ordered a screening mammography. However, patients had many barriers and were not able to schedule this appointment. The QI team proposed a new idea of sharing open appointment slots for our clinic patients with a nurse navigator in the clinic, and appointments were scheduled before patients were discharged from the clinic. This new workflow helped tremendously; patients were appreciative of getting appointment and were able to keep the appointment due to the open-access calendar from the mammography mobile coach. Many patients lost their prescription for a mammogram order; therefore, the clinic administrative staff developed a new process of faxing the mammogram order to the mammography mobile bus. The nurse navigator sent a task to physicians in the EHR to create a mammogram order for due or overdue mammography when patients were not scheduled in the clinic. The team noticed a delay in receiving an order from physicians; therefore, the team designed a new clinic protocol for a standing order for a screening mammogram. The nurse navigator and clinic administrative staff generated the mammogram order and faxed it to the mammography mobile bus. The mammography mobile bus staff reminded patients for a scheduled appointment through automated phone calls and sent letters to reschedule when patients missed their appointment. The nurse navigator reviewed a monthly list of overdue/due patients, generated by the electronic patient registry and called patients to reinforce the mammogram recommendation and scheduled mammography. Due to limited resources, the nurses were unable to implement workflow for previsit planning to identify patients who were due for mammogram and to create a chart alert for physicians. Regular team meetings with the residents and QI team members led to redesigning of workflow and various interventions. The lack of clinical decision support tool was identified as the biggest barrier.
There are few limitations in this study. The QI project was conducted in a safety-net primary care clinic, focusing on patients with multiple comorbidities. As a result, the barriers and interventions identified may not be directly generalisable to other healthcare settings with different patient populations or resources. The unique characteristics of the safety-net clinic and its patient population may have influenced the study outcomes. The study may have underestimated breast cancer screening rates for two reasons. First, the inability to access mammogram reports performed at outside facilities may have led to incomplete data on completed screening. This limitation may have affected the accuracy of the screening rate calculations. Second, although efforts were made to integrate mammogram reports into the EHR during screening conducted in the mobile coach bus, the process was not consistently successful. Consequently, completed mammogram orders were not captured as structured data, potentially resulting in an underestimation of the screening rates. Time constraints on clinic staff may have hindered the manual completion of mammogram orders and contributed to the inaccuracy in the electronic database.
This study stands out due to the implementation of multifaceted strategies within a unique setting, specifically using a mobile mammography bus to address social determinants of health in a marginalised population. Notably, the project incurred minimal costs, making it a cost-effective initiative. The patient navigator dedicated an average of 4–6 hours per week, ensuring the smooth functioning of the intervention. The study demonstrated internal validity. The clinical workflow and EHR enhancements developed during the project have now become the standard of care for breast cancer screening in IMC. Moreover, hospital and clinic administrative leadership has fostered a patient safety and quality culture. These attributes will ensure the sustainability of this QI project. Offering transportation assistance for mammogram is facilitated by a clinic social worker. In New York state, the Medicaid Transportation Programme ensures patients with Medicaid insurance can get to and from their medical appointments at no cost to them.34 The social worker assists patients to schedule transportation for a prescheduled appointment to primary care and for necessary testing. Trips are arranged at the most medically appropriate, cost-effective level of service. These include public transit, taxi, wheelchair van and personal vehicle mileage reimbursement. Members generally travel using the same mode they use for daily living. Patients with other insurance who need transportation will have an option of scheduling mammogram within a walking distance from their home in a mobile mammography bus and/or schedule at a time when the patient can get a ride from a family or a friend. These strategies can be feasible and sustainable in the long term to assist patients for appointments to primary care provider and mammogram. Various system-level long-lasting changes in the EHR, clinic operation and workflow are integrated as a standard of care and will be sustainable.
The success of these strategies suggests their potential for replication in other healthcare settings, particularly those serving under-resourced populations. During the post-study period, the team organised a fair and educational workshop in the hospital to raise breast cancer awareness among patients, visitors and employees. Future directions for this project involve assessing barriers for patients’ refusal, implementing motivational interview techniques to help physicians overcome barriers to screening mammograms, enhancing patient education through educational videos and conducting outreach to eligible patients who were lost to follow-up in the IMC. These future directions highlight the team’s commitment to continuous improvement and population health management.
Conclusions
In conclusion, this study demonstrates the effectiveness of multifaceted strategies, including the utilisation of a mobile mammography coach bus, in advancing health equity to improve breast cancer screening rates. Use of a patient navigator, optimisation of EHR, improving access by using a mobile mammography bus and highly engaged multidisciplinary team were the critical factors for the success of this QI study. The findings contribute to the growing body of knowledge on breast cancer screening interventions and provide valuable insights for future QI projects in healthcare.
