BACKGROUND: Digital phenotyping may detect changes in health outcomes and potentially lead to proactive measures to mitigate health declines and avoid major medical events. While health-related outcomes have traditionally been acquired through self-report measures, those approaches have numerous limitations, such as recall bias, and social desirability bias. Digital phenotyping may offer a potential solution to these limitations. OBJECTIVES: The purpose of this scoping review was to identify and summarize how passive smartphone data are processed and evaluated analytically, including the relationship between these data and health-related outcomes. METHODS: A search of PubMed, Scopus, Compendex, and HTA databases was conducted for all articles in April 2021 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Review (PRISMA-ScR) guidelines. RESULTS: A total of 40 articles were included and went through an analysis based on data collection approaches, feature extraction, data analytics, behavioral markers, and health-related outcomes. This review demonstrated a layer of features derived from raw sensor data that can then be integrated to estimate and predict behaviors, emotions, and health-related outcomes. Most studies collected data from a combination of sensors. GPS was the most used digital phenotyping data. Feature types included physical activity, location, mobility, social activity, sleep, and in-phone activity. Studies involved a broad range of the features used: data preprocessing, analysis approaches, analytic techniques, and algorithms tested. 55% of the studies (n = 22) focused on mental health-related outcomes. CONCLUSION: This scoping review catalogued in detail the research to date regarding the approaches to using passive smartphone sensor data to derive behavioral markers to correlate with or predict health-related outcomes. Findings will serve as a central resource for researchers to survey the field of research designs and approaches performed to date and move this emerging domain of research forward towards ultimately providing clinical utility in patient care.

PURPOSE: Despite the growing calls for early and ubiquitous completion of advance directives (ADs), studies exploring links between AD completion and their impact on outcomes of patients with cancer have mixed conclusions. We used the ASCO Quality Oncology Practice Initiative (QOPI) registry to compare end-of-life (EOL) quality measures and the effect of QOPI certification among patients with and without early AD completion, defined as completion within the first three oncology visits after cancer diagnosis. METHODS: Deidentified patient-level data were analyzed from the QOPI database from 2015 through 2017. Associations were assessed using Chi-square tests between early AD completion and patient enrollment in hospice < 7 days before death, chemotherapy receipt in the last 14 days of life, or with emergency room visits or intensive care unit admissions in the last 30 days of life. RESULTS: Data from 31,558 patients eligible for the AD question were analyzed. Patients treated at QOPI-certified practices had higher rates of early AD completion than patients at non-certified practices. Early AD completion was not associated with differences in hospice enrollment for < 7 days before death, chemotherapy receipt in the last 14 days of life, or emergency room visits or intensive care unit encounters in the last 30 days of life. CONCLUSION: The study found that QOPI certification is associated with higher rates of early AD completion. However, early AD completion was not associated with recognized EOL quality measures. Future research should focus on the timing, frequency, and content of AD conversations to demonstrate the impact on care at the EOL.

PURPOSE: American Society for Clinical Oncology released the Choosing Wisely list in 2012, highlighting low-value procedures that lack evidence, advising against the use of positron emission tomography, computerized tomography, and radionuclide bone scans for the staging of early-stage breast cancer at low risk for metastasis. The objective of the study was to assess the impact of the American Society of Clinical Oncology Choosing Wisely guidelines on inappropriate staging imaging among early-stage breast cancers. METHODS: The Surveillance, Epidemiology, and End Results Program-Medicare data set was used to identify 50,004 women age 66 years and older with new incident diagnosis of early-stage breast cancer (stage 0 through stage 2a; T < 4, N = 0, and M = 0). The primary outcome was the incidence of patients with inappropriate imaging following an early-stage breast cancer diagnosis. The primary outcome was identified within 6 months of the first diagnosis. An interrupted time series analysis using negative binomial regression was performed for outpatient claims for these diagnostic studies versus the two interruptions of guidelines release and guidelines reinforcement. Mean images per patient, percent change for the study period, and rate of change per year were calculated. RESULTS: Imaging rates fell by a modest 2.32% following guidelines release in April 2012 (point estimate = -2.32%; 95% CI, -6.34% to 1.88%). By contrast, imaging rates fell by a four-fold larger amount (point estimate = -9.36%; 95% CI, -13.20% to -5.35%) following guidelines published reminders in journals (or reinforcement) in October 2013. Mean imaging studies per patient (95% CI) declined from 1.80 (1.76 to 1.84) in January 2012 to 1.50 (1.48 to 1.53) by January 2015, representing a 16% decline in imaging overuse in 2015 compared with 3 years earlier. The rate of change (95% CI) in images per patient was initially small at -0.47% (-4.27% to 3.33%) per year between April 2012 and October 2013, but almost eight times faster at -3.70% (-5.81% to -1.60%) per year after October 2013. CONCLUSION: This analysis demonstrates a substantial decrease in the prevalence of imaging overuse in early-stage breast cancers correlating with the 2013 reinforcement of American Society of Clinical Oncology's 2012 Choosing Wisely guidelines. The creation and dissemination of such resources serves as a powerful tool to improve clinical practice, cost-effectiveness, and patient safety from secondary malignancies, anxiety, and overdiagnosis.

Background and Objectives: Historically marginalized religious and cultural groups are at risk for lower quality of care than majority groups. No study to date specifically queries Muslim experiences with the American health care system (AHCS). We performed a thematic analysis of Muslim parents' interactions with the AHCS and how their background informs their approach to care. Methods: This was a qualitative study of Muslim parents of children with life-limiting conditions in the Research Triangle Area from December 2019 to March 2019. We conducted semistructured interviews with parents to assess their experiences with the AHCS. We probed interview transcripts using descriptive content analysis with NVivo10. Results: We interviewed 10 parents in the Research Triangle Area. All patients were female, most were married, most spoke at least one other language in addition to English, and most were not born in the United States. Several themes emerged highlighting open communication with care teams, willingness to share religious affiliations, and the importance of leaning into faith and accepting God's will. Conclusions: A thematic analysis of Muslim parents' interactions with the AHCS describes value in honest communication, mixed concerns about how providers will react to their religious affiliation, and emphasizes the importance of leaning heavily into faith and accepting God's plan. Future studies evaluating needs of Muslim patients, especially those with different diagnoses, language barriers, and a larger sample size will further delineate needs to minimize inequalities in care.

CONTEXT: While progress has been made in the ability to measure the quality of hospice and specialty palliative care, there are notable gaps. A recent analysis conducted by Center for Medicare and Medicaid Services (CMS) revealed a paucity of patient-reported measures, particularly in palliative care domains such as symptom management and communication. OBJECTIVES: The research team, consisting of quality measure and survey developers, psychometricians, and palliative care clinicians, used established state-of-the art methods for developing and testing patient-reported measures. METHODS: We applied a patient-centered, patient-engaged approach throughout the development and testing process. This sequential process included 1) an information gathering phase; 2) a pre-testing phase; 3) a testing phase; and 4) an endorsement phase. RESULTS: To fill quality measure gaps identified during the information gathering phase, we selected two draft measures ("Feeling Heard and Understood" and "Receiving Desired Help for Pain") for testing with patients receiving palliative care in clinic-based settings. In the pre-testing phase, we used an iterative process of cognitive interviews to refine draft items and corresponding response options for the proposed measures. The alpha pilot test supported establishment of protocols for the national beta field test. Measures met conventional criteria for reliability, had strong face and construct validity, and there was diversity in program level scores. The measures received National Quality Forum (NQF) endorsement. CONCLUSION: These measures highlight the key role of patient voices in palliative care and fill a much-needed gap for patient-reported experience measures in our field.
