OBJECTIVE: To examine sexual minority compared to heterosexual survivors' health-related anxiety, anxiety, and depression. METHODS: Four hundred and eighty eligible survivors participated in a telephone survey, which measured their anxiety and depression. These survivors were diagnosed with stage I, II, or III colorectal cancer an average of three years prior to the survey and were recruited from four cancer registries. As explanatory factors, we considered individual, social and contextual characteristics, prior psychological factors, psychological responses to cancer, and characteristics of cancer and its treatments. Using forward selection with generalized linear models or logistic regression models, we identified significant correlates for each outcome. RESULTS: Prior to adjusting for covariates, depression was similar for all survivors, while sexual minority survivors had worse health-related anxiety and anxiety compared to heterosexual survivors. After adjustment, these differences were no longer statistically significant. Individual, social and contextual characteristics, characteristics of cancer, and psychological responses to cancer explained 44% of the variance in anxiety and 60% of the variance in depression. CONCLUSION: There are modifiable factors associated with health-related and generalized anxiety as well as depression that can be changed to improve cancer survivorship among diverse survivors.

BACKGROUND: The purpose of this study was to examine the health-related quality of life of sexual minority survivors in comparison with heterosexual survivors. METHODS: Four hundred eighty eligible survivors participated in a telephone survey that measured survivors' outcomes, which consisted of physical and mental quality of life and self-rated fair or poor health. These survivors were diagnosed with stage I, II, or III colorectal cancer an average of 3 years before the survey and were recruited from 4 cancer registries. Using forward selection with generalized linear models or logistic regression models, the authors considered 4 domains-personal factors, environmental factors, health condition characteristics, and body function and structure-as correlates for each survivorship outcome. RESULTS: The authors found that unadjusted physical quality of life and self-rated fair/poor health were similar for all survivors. Sexual minority survivors had poorer unadjusted mental quality of life in comparison with heterosexual survivors. After adjustments for covariates, this difference was no longer statistically significant. Three domains (personal factors, health condition characteristics, and body function and structure) explained colorectal cancer survivors' fair/poor health and 46% of the variance in physical quality of life, whereas 56% of the variance in mental quality of life was explained by personal factors, body function and structure, and environmental factors. CONCLUSIONS: This study has identified modifiable factors that can be used to improve cancer survivors' quality of life and are, therefore, relevant to ongoing efforts to improve the survivorship experience.

PURPOSE: The purpose of this study was to examine receipt of follow-up surveillance among sexual minority and heterosexual survivors and identify survivor-, physician-, and practice-level characteristics associated with follow-up surveillance. METHODS: An average of 3 years after their stage I-III colorectal cancer diagnosis, we recruited survivors from four cancer registries. A questionnaire, which queried about sexual orientation and other eligibility criteria, was mailed to all cancer survivors. Subsequently, 418 eligible survivors without recurrent disease participated in a telephone survey. Colorectal cancer-specific follow-up surveillance was defined as colonoscopy, carcinoembryonic antigen (CEA) test, or imaging test. We used logistic regression with forward selection to obtain models that best explained each follow-up test. RESULTS: About 10% of survivors received no follow-up surveillance, while 70% had colonoscopies. While survivors irrespective of sexual orientation received follow-up surveillance, sexual minority survivors had 3 times the odds of receiving imaging tests compared to heterosexual survivors. Having a designated provider of any specialty was most salient for the receipt of surveillance. CONCLUSIONS: Sexual minority survivors' greater receipt of imaging tests may indicate providers perceive them at greater risk for recurrence than heterosexual survivors. Future studies need to examine provider behaviors towards monitoring colorectal cancer survivors of diverse sexual orientations. IMPLICATIONS FOR CANCER SURVIVORS: Guidelines recommend surveillance of colorectal cancer survivors to improve survival. This study showed that having a designated provider for follow-up is most salient for the receipt of surveillance, most survivors receive surveillance, and sexual minority survivors had more imaging tests compared to heterosexual survivors.

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia during critical illness, representing a sepsis-defining cardiac dysfunction associated with adverse outcomes. Large burdens of premature beats and noisy signal during sepsis may pose unique challenges to automated AF detection. OBJECTIVE: The objective of this study is to develop and validate an automated algorithm to accurately identify AF within electronic health care data among critically ill patients with sepsis. METHODS: This is a retrospective cohort study of patients hospitalized with sepsis identified from Medical Information Mart for Intensive Care (MIMIC III) electronic health data with linked electrocardiographic (ECG) telemetry waveforms. Within 3 separate cohorts of 50 patients, we iteratively developed and validated an automated algorithm that identifies ECG signals, removes noise, and identifies irregular rhythm and premature beats in order to identify AF. We compared the automated algorithm to current methods of AF identification in large databases, including ICD-9 (International Classification of Diseases, 9th edition) codes and hourly nurse annotation of heart rhythm. Methods of AF identification were tested against gold-standard manual ECG review. RESULTS: AF detection algorithms that did not differentiate AF from premature atrial and ventricular beats performed modestly, with 76% (95% CI 61%-87%) accuracy. Performance improved (P=.02) with the addition of premature beat detection (validation set accuracy: 94% [95% CI 83%-99%]). Median time between automated and manual detection of AF onset was 30 minutes (25th-75th percentile 0-208 minutes). The accuracy of ICD-9 codes (68%; P=.002 vs automated algorithm) and nurse charting (80%; P=.02 vs algorithm) was lower than that of the automated algorithm. CONCLUSIONS: An automated algorithm using telemetry ECG data can feasibly and accurately detect AF among critically ill patients with sepsis, and represents an improvement in AF detection within large databases.

Purpose: Quality cancer care entails receipt of a Survivorship Care Plan (SCP). The purpose of this study was to determine differences in SCP delivery by patient-level and neighborhood characteristics. Methods: We obtained California cancer registry data on individuals who were diagnosed with stage I, II, or III colorectal cancer (CRC) between 2012 and 2015 and resided in predetermined geographic areas. We then mailed them a questionnaire, which queried about receipt of a SCP and its content. SCP was defined by content, as summary of cancer treatment, cancer surveillance recommendations, and/or an individualized preventive care. Using logistic regression modeling, each measure of SCP, as well as the summary measure (none vs. any), was evaluated by person-level characteristics. Subsequently, neighborhood-level characteristics were added to the model to explore their additional value. Results: Overall 80% of CRC survivors received a SCP. Receipt of SCPs was associated with person-level characteristics, while neighborhood characteristics did not make an additional contribution. Young, male employed survivors and those with more recent diagnoses or later cancer stages had greater odds of receiving a SCP. Conclusion: When providing SCPs, health care providers prioritize patient groups who they may perceive as vulnerable or likely to benefit from SCPs.

OBJECTIVE: The objective of the study is to assess dyadic stress among sexual minority cancer survivor and caregivers compared to heterosexual cancer survivors and their caregivers. METHODS: We recruited 167 survivors of nonmetastatic breast cancer of different sexual orientations and their caregivers, who were interviewed via telephone after obtaining consent. We used inverse propensity score weighting to account for differences by sexual orientation in age and length of the survivor-caregiver relationship and simultaneous equation models consistent with the needs for analyzing dyadic data. RESULTS: Survivors and caregivers reported stress levels consistent with population norms, irrespective of survivors' sexual orientation. Accounting for covariates, survivors' and caregivers' stress did not mutually influence one another overall. However, differences by sexual orientation were noted such that caregivers' stress was influential for sexual minority survivors' stress, but not for heterosexual survivors' stress. CONCLUSIONS: Careful consideration should be given to caregivers of sexual minority survivors, an underserved group for whom currently no interventions exist.
