Determinants of Guideline-Discordant Breast Cancer Care.

ABSTRACT:

Background

Evidence-based breast cancer treatment guidelines recommend the most appropriate course of therapy based on tumor characteristics and extent of disease. Evaluating the multilevel factors associated with guideline discordance is critical to identifying strategies to eliminate breast cancer survival disparities.

Methods

We identified females diagnosed with a first primary, stage I-III breast cancer between the ages of 20-69 years of age from the population-based Seattle-Puget Sound Surveillance, Epidemiology, and End Results registry. Participants completed a survey about social support, utilization of patient support services, hypothesized barriers to care, and initiation of breast cancer treatment. We used logistic regression to estimate odds ratios and 95% confidence intervals (CI).

Results

Among 1,390 participants, 10% reported guideline-discordant care. In analyses adjusted for patient-level sociodemographic factors, individuals who did not have someone to go with them to appointments or drive them home (OR 1.96; 95% CI, 1.09-3.59) and those who had problems talking to their doctors or their staff (OR 2.03; 95% CI, 1.13-3.64) were more likely to be guideline discordant than those with social support or without such problems, respectively. Use of patient support services was associated with a 43% lower odds of guideline discordance (OR 0.57; 95% CI, 0.36-0.88).

Conclusions

Although guideline discordance in this cohort of early-stage breast cancer survivors diagnosed <70 years of age was low, instrumental social support, patient support services, and communication with doctors and their staff emerged as potential multilevel intervention targets for improving breast cancer care delivery.

Impact

This study supports extending the reach of interventions designed to improve guideline concordance.

Project description:Approximately half of veterans with low-risk prostate cancer receive guideline-discordant imaging. Our objective was to identify and describe (1) physician knowledge, attitudes, and practices related to the use of imaging to stage prostate cancer, (2) patient attitudes and behaviors related to use of imaging, and (3) to compare responses across three VA medical centers (VAMCs).A qualitative approach was used to explore patient and provider knowledge and behaviors relating to the use of imaging. We conducted 39 semi-structured interviews total-including 22 interviews with patients with newly diagnosed with prostate cancer and 17 interviews with physicians caring for them-between September 2014 and July 2015 at three VAMCs representing a spectrum of inappropriate imaging rates. After core theoretical concepts were identified, the Theoretical Domains Framework (TDF) was selected to explore linkages between themes within the dataset and existing domains within the framework. Interviews were audio-recorded, transcribed verbatim, and then coded and analyzed using Nvivo software.Themes from patient interviews were categorized within four TDF domains. Patients reported little interest in staging as compared to disease treatment (goals), and many could not remember if they had imaging at all (knowledge). Patients tended to trust their doctor to make decisions about appropriate tests (beliefs about capabilities). Some patients expressed a minor concern for radiation exposure, but anxiety about cancer outcomes outweighed these fears (emotion). Themes from physician interviews were categorized within five TDF domains. Most physicians self-reported that they know and trust imaging guidelines (knowledge) yet some were still likely to follow their own intuition, whether due to clinical suspicion or years of experience (beliefs about capabilities). Additionally, physicians reported that medico-legal concerns, fear of missing associated diagnoses (beliefs about consequences), influence from colleagues who image frequently (social influences), and the facility where they practice influences rates of imaging (environmental context).Interviews with patients and physicians suggest that physicians are the primary (and in some cases only) decision-makers regarding staging imaging for prostate cancer. This finding suggests a physician-targeted intervention may be the most effective strategy to improve guideline-concordant prostate cancer imaging.

Project description:BackgroundThe National Cancer Institute Community Cancer Centers Program (NCCCP) pilot was designed to improve quality of cancer care and reduce disparities at community hospitals. The NCCCP's primary intervention was the implementation of the Commission on Cancer Rapid Quality Reporting System (RQRS). The RQRS is a hospital-based data collection and evaluation system allowing near real-time assessment of selected breast and colon cancer quality of care measures. Building on previous NCCCP analyses, this study examined whether improvements in quality cancer care within NCCCP hospitals early in the program were sustained and whether improvements were notable for minority or underserved populations.MethodsWe compared changes in concordance with three breast and two colon cancer quality measures approved by the National Quality Forum for patients diagnosed at NCCCP hospitals from 2006 to 2007 (pre-RQRS), 2008 to 2010 (early-RQRS), and 2011 to 2013 (later-RQRS). Data were obtained from NCCCP sites participating in the Commission on Cancer Rapid Quality Reporting System. Logistic regression analyses were performed to identify predictors of concordance with breast and colon cancer quality measures.ResultsThe sample included 13,893 breast and 5,546 colon cancer patients. After RQRS initiation, all five quality measures improved significantly and improvements were sustained through 2013. Quality of care measures showed sustained improvements for both breast and colon cancer patients and for vulnerable patient subgroups including black, uninsured, and Medicaid-covered patients.ConclusionsQuality improvements in NCCCP hospitals were sustained throughout the duration of the program, both overall and among minority and underserved patients. Because many individuals receive cancer treatment at community hospitals, facilitating high-quality care in these environments must be a priority.Implications for practiceQuality improvement programs often improve practice, but the methods are not maintained over time. The implementation of a real-time quality reporting system and a network focused on improving quality of care sustained quality improvement at select community cancer centers. The NCCCP pilot increased numbers of patients receiving guideline-concordant care for breast and colon cancer in community settings, and initial improvements noted in earlier years of RQRS were sustained into later years, both overall and among minority and underserved patients. National initiatives that improve care for diverse patient groups are important for reducing and eliminating barriers to care.

Project description:IntroductionDespite evidence of possible patient harm and substantial costs, medication overuse is persistent. Patient reaction is one potential barrier to deprescribing, but little research has assessed this in specific instances of medication discontinuation. We sought to understand Veteran and provider experience when de-implementing guideline-discordant use of inhaled corticosteroids (ICS) in those with mild-to-moderate chronic obstructive pulmonary disease (COPD).MethodsWe conducted a mixed-methods analysis in a provider-randomized quality improvement project testing a proactive electronic-consultation from pulmonologists recommending ICS discontinuation when appropriate. PCPs at two Veterans Health Administration healthcare systems were included. We completed interviews with 16 unexposed providers and 6 intervention-exposed providers. We interviewed 9 patients within 3 months after their PCP proposed ICS discontinuation. We conducted inductive and deductive content analysis of qualitative data to explore an emergent theme of patient reaction. Forty-eight PCPs returned surveys (24 exposed and 24 unexposed, response rate: 35%).ResultsThe unexposed providers anticipated their patients might resist ICS discontinuation because it seems counterintuitive to stop something that is working, patient's fear of worsening symptoms, or if the prescription was initiated by another provider. Intervention-exposed providers reported similar experiences in post-intervention interviews. Unexposed providers anticipated that patients may accept ICS discontinuation, citing tactical use of patient-centered care strategies. This was echoed by intervention-exposed providers who had successfully discontinued an ICS. Veterans reported acceding to their providers out of trust or deference to their advanced training, even after describing an ICS as a 'security blanket'. Our survey findings supported the subthemes from our interviews. Among providers who proposed discontinuation of an ICS, 76% reported that they were able to discontinue it or switch to another more appropriate medication.ConclusionsWhile PCPs anticipated that patients would resist discontinuing an ICS, interviews with patient and intervention-exposed PCPs along with surveys suggest that patients were receptive to this change.
