Item Anxiogenic CO2 Stimulus Elicits Exacerbated Hot Flash-like Responses in a Rat Menopause Model and Hot Flashes in Menopausal Women(Lippincott, Williams & Wilkins, 2016-11) Federici, Lauren M.; Roth, Sarah Dorsey; Krier, Connie; Fitz, Stephanie D.; Skaar, Todd C.; Shekhar, Anantha; Carpenter, Janet S.; Johnson, Philip L.; Anatomy and Cell Biology, School of MedicineObjective Since longitudinal studies determined that anxiety is a strong risk factor for hot flashes, we hypothesized that an anxiogenic stimulus that signals air hunger (hypercapnic, normoxic gas) would trigger an exacerbated hot flash-associated increase in tail skin temperature (TST) in a rat ovariectomy (OVEX) model of surgical menopause and hot flashes in symptomatic menopausal women. We also assessed TST responses in OVEX serotonin transporter (SERT)+/− rats that models a common polymorphism that is associated with increased climacteric symptoms in menopausal women and increases in anxiety traits. Methods OVEX and sham-OVEX rats (initial experiment) and wildtype and SERT+/− OVEX rats (subsequent experiment) were exposed to a 5 min infusion of 20%CO2 normoxic gas while measuring TST. Menopausal women were given brief 20% and 35%CO2 challenges, and hot flashes were self-reported and objectively verified. Results Compared to controls, OVEX rats had exacerbated increases in TST, and SERT+/− OVEX rats had prolonged TST increases following CO2. Most women reported mild/moderate hot flashes after CO2 challenges, and the hot flash severity to CO2 was positively correlated with daily hot flash frequency. Conclusions The studies demonstrate that this anxiogenic stimulus is capable of inducing cutaneous vasomotor responses in OVEX rats, and eliciting hot flashes in menopausal women. In rats, the severity of the response was mediated by loss of ovarian function and increased anxiety traits (SERT+/−), and, in women, by daily hot flash frequency. These findings may provide insights into anxiety related triggers and genetic risk factors for hot flashes in thermoneutral environments.Item Computer-tailored intervention increases colorectal cancer screening among low-income African Americans in primary care: Results of a randomized trial(Elsevier, 2021) Rawl, Susan M.; Christy, Shannon M.; Perkins, Susan M.; Tong, Yan; Krier, Connie; Wang, Hsiao-Lan; Huang, Amelia M.; Laury, Esther; Rhyant, Broderick; Lloyd, Frank; Willis, Deanna R.; Imperiale, Thomas F.; Myers, Laura J.; Springston, Jeffrey; Sugg Skinner, Celette; Champion, Victoria L.; School of NursingIntroduction: Although African Americans have the highest colorectal cancer (CRC) incidence and mortality rates of any racial group, their screening rates remain low. Study design/purpose: This randomized controlled trial compared efficacy of two clinic-based interventions for increasing CRC screening among African American primary care patients. Methods: African American patients from 11 clinics who were not current with CRC screening were randomized to receive a computer-tailored intervention (n = 335) or a non-tailored brochure (n = 358) designed to promote adherence to CRC screening. Interventions were delivered in clinic immediately prior to a provider visit. Univariate and multivariable logistic regression models analyzed predictors of screening test completion. Moderators and mediators were determined using multivariable linear and logistic regression analyses. Results: Significant effects of the computer-tailored intervention were observed for completion of a stool blood test (SBT) and completion of any CRC screening test (SBT or colonoscopy). The colonoscopy screening rate was higher among those receiving the computer-tailored intervention group compared to the nontailored brochure but the difference was not significant. Predictors of SBT completion were: receipt of the computer-tailored intervention; being seen at a Veterans Affairs Medical Center clinic; baseline stage of adoption; and reason for visit. Mediators of intervention effects were changes in perceived SBT barriers, changes in perceived colonoscopy benefits, changes in CRC knowledge, and patient-provider discussion. Moderators of intervention effects were age, employment, and family/friend recommendation of screening. Conclusion: This one-time computer-tailored intervention significantly improved CRC screening rates among low-income African American patients. This finding was largely driven by increasing SBT but the impact of the intervention on colonoscopy screening was strong. Implementation of a CRC screening quality improvement program in the VA site that included provision of stool blood test kits and follow-up likely contributed to the strong intervention effect observed at that site.Item Development of a Computer-Tailored Intervention/Decision Aid To Increase Colorectal Cancer Screening in Health Systems(Cureus, 2022-03-21) Fatima, Hala; Wajid, Maryiam; Krier, Connie; Champion, Victoria; Carter-Harris, Lisa; Shedd-Steele, Rivienne; Imperiale, Thomas F.; Schwartz, Peter; Strom, Sylvia; Magnarella, Mark; Rawl, Susan M.; Medicine, School of MedicineBackground: Non-compliance with scheduled colonoscopy is common among patients, especially in underserved populations. High no-show and late cancelation rates result in wasted resources, increased costs, and missed opportunities for colorectal cancer (CRC) screening. Among the barriers to colonoscopy is a lack of knowledge about the benefits, fears, and limited time for patient counseling. Methodology: We produced a digital video disc and a website program to enhance awareness about CRC screening and address patient barriers in a population with low screening adherence. Results: Patients can be educated via an interactive computer-tailored intervention with both DVD and web versions. It details the benefits and need for CRC screening, different methods of screening, and addresses patient-related barriers. Conclusions: Patient education is crucial to increase CRC screening among eligible individuals. Because online engagement is affected by attention, interest, and affect, content should be concise but comprehensive.Item Interventions to Promote Colorectal Cancer Screening in Primary Care: Results of a Randomized Trial(Office of the Vice Chancellor for Research, 2013-04-05) Rawl, Susan M.; Christy, Shannon M.; Perkins, Susan; Tong, Yan; Krier, Connie; Wang, Hsiao-Lan; Champion, Victoria L.; Myers, Laura Jones; Imperiale, Thomas; Willis, Deanna; Rhyant, Broderick; Springston, Jeffrey; Skinner, Celette SuggAims: The purpose of this randomized trial was to compare rates of self-reported colorectal cancer (CRC) screening and forward movement in stage of adoption at 6 months post-intervention. African American primary care patients (n=595) who were eligible for CRC screening were randomly assigned to receive a computer-delivered tailored CRC screening intervention (n=286) or a non-tailored screening brochure (n=309) prior to their scheduled visit with their primary care provider. Hypotheses were that differences between groups would be observed in proportions of patients who: 1) completed fecal occult blood tests (FOBT) or colonoscopy; and 2) had moved forward in stages of adoption for these tests. Methods: Participants completed baseline and 6-month telephone interviews; interventions were delivered prior to primary care provider visits. Differences between groups were examined using chi-square tests, predictors of screening were determined using logistic regression models. Results: In the computer-tailored group, the FOBT completion rate was 12.6% compared to 7.8% in the brochure group (p=0.05). The colonoscopy completion rate was 17.5% in the computer group vs. 15.2% in the brochure group (p=0.45). Forward stage movement for FOBT was observed in 28.4% of the computer groups vs. 20.8% in the brochure group (p=0.03). Forward stage movement for colonoscopy was 38.5% in the computer group and 36.8% (p=0.68) in each group, respectively. Conclusions: The computer-tailored intervention was more effective than the brochure at increasing FOBT completion and movement toward action. More research is needed to explain why the tailored intervention was not more effective at increasing colonoscopy completion and to identify moderators of intervention efficacy.Item Partnering to Increase Colorectal Cancer Screening: Perspectives of Community Advisory Board Members(Sage, 2021-10) Rawl, Susan M.; Bailey, Sandra; Cork, Beatrice; Fields, Matthew; Griffin, Thomas; Haunert, Laura; Kline, Judy; Krier, Connie; Lagunes, Juan; Lambert, Ruth L.; Malloy, Caeli; Quick, Jack; Shedd-Steele, Rivienne; Strom, Sylvia; Carter-Harris, Lisa; School of NursingThe Patient-Centered Outcomes Research Institute (PCORI) defines engagement in research as the meaningful involvement of patients, caregivers, clinicians, insurers, and others throughout the entire research process – from planning, to conducting the study, to disseminating study results. The purposes of this paper are to: 1) describe methods used to engage community members across the various phases of a PCORI-funded comparative effectiveness trial to increase colorectal cancer screening; and 2) report results of qualitative and quantitative evaluations of community advisory board members’ experiences on this project. Decisions to join and stay engaged with the study included feeling valued and appreciated, being compensated, the opportunity to contribute to research based on their skills and expertise, and being committed to colon cancer prevention efforts. Challenges identified by advisory board members included the significant time commitment, transportation, and meeting location. Lessons learned and guidance for researchers committed to patient and community engagement are described.Item Patient Navigation Plus Tailored Digital Video Disc Increases Colorectal Cancer Screening Among Low-Income and Minority Patients Who Did Not Attend a Scheduled Screening Colonoscopy: A Randomized Trial(Oxford University Press, 2024) Rawl, Susan M.; Perkins, Susan M.; Tong, Yan; Katz, Mira L.; Carter-Bawa, Lisa; Imperiale, Thomas F.; Schwartz, Peter H.; Fatima, Hala; Krier, Connie; Tharp, Kevin; Shedd-Steele, Rivienne; Magnarella, Mark; Malloy, Caeli; Haunert, Laura; Gebregziabher, Netsanet; Paskett, Electra D.; Champion, Victoria; School of NursingBackground: Up to 50% of people scheduled for screening colonoscopy do not complete this test and no studies have focused on minority and low-income populations. Interventions are needed to improve colorectal cancer (CRC) screening knowledge, reduce barriers, and provide alternative screening options. Patient navigation (PN) and tailored interventions increase CRC screening uptake, however there is limited information comparing their effectiveness or the effect of combining them. Purpose: Compare the effectiveness of two interventions to increase CRC screening among minority and low-income individuals who did not attend their screening colonoscopy appointment-a mailed tailored digital video disc (DVD) alone versus the mailed DVD plus telephone-based PN compared to usual care. Methods: Patients (n = 371) aged 45-75 years at average risk for CRC who did not attend a screening colonoscopy appointment were enrolled and were randomized to: (i) a mailed tailored DVD; (ii) the mailed DVD plus phone-based PN; or (iii) usual care. CRC screening outcomes were from electronic medical records at 12 months. Multivariable logistic regression analyses were used to study intervention effects. Results: Participants randomized to tailored DVD plus PN were four times more likely to complete CRC screening compared to usual care and almost two and a half times more likely than those who were sent the DVD alone. Conclusions: Combining telephone-based PN with a mailed, tailored DVD increased CRC screening among low-income and minority patients who did not attend their screening colonoscopy appointments and has potential for wide dissemination.Item Predictors of stage of adoption for colorectal cancer screening among African American primary care patients(Ovid Technologies (Wolters Kluwer) - Lippincott Williams & Wilkins, 2014-07) Wang, Hsiao-Lan; Christy, Shannon M.; Skinner, Celette S.; Champion, Victoria L.; Springston, Jeffrey K.; Perkins, Susan M.; Tong, Yan; Krier, Connie; Gebregziabher, Netsanet; Rawl, Susan M.; Department of Psychology, School of ScienceBACKGROUND: Compared with other racial groups, African Americans have the highest colorectal cancer (CRC) incidence and mortality rates coupled with lower screening rates. OBJECTIVE: Our study examined the predictors of stage of adoption for fecal occult blood testing (FOBT) and colonoscopy among African American primary care patients who were nonadherent to published screening guidelines. METHODS: Baseline data (N = 815) in a randomized clinical trial were analyzed. Participants were categorized into precontemplation, contemplation, and preparation stages for FOBT and colonoscopy. Predictor variables were demographics, clinical variables, CRC health beliefs and knowledge, and social support. Hierarchical modeling was to identify significant predictors of stage of adoption. RESULTS: Older, male, Veterans Affairs participants and those with higher perceived self-efficacy, family/friend encouragement, and a provider recommendation had higher odds of being at a more advanced stage of adoption for FOBT. Patients with a history of cancer and higher perceived barriers had higher odds of being at an earlier stage of adoption for FOBT. Predictors of more advanced stage of adoption for colonoscopy included higher perceived benefits, higher perceived self-efficacy, family/friend encouragement, and a provider recommendation for colonoscopy. Higher income (>30 000 vs <15 000) was predictive of earlier stage of adoption for colonoscopy. CONCLUSIONS: Enhancing self-efficacy, encouragement from family and friends, and provider recommendations are important components of interventions to promote CRC screening. IMPLICATIONS FOR PRACTICE: Nurses can use knowledge of the characteristics associated with stage of adoption to educate and motivate their African American primary care patients to complete CRC screening tests.Item Primary Care Patients Who Complete Colonoscopy after Referral and Those Who Do Not: Are they Different?(Office of the Vice Chancellor for Research, 2014-04-11) Olofinkua, Oluwakemi Blessing; Rawl, Susan M.; Habermann, Barbara; Christy, Shannon M.; Perkins, Susan; Tong, Yan; Gebregziabher, Netsanet; Mabis, Michelle; Krier, Connie; Mirchandani, Amit; Fatima, HalaUp to 50% of people in one safety net hospital in the Midwest who received a recommendation for colonoscopy from their healthcare provider failed to complete the test. Research is needed to understand the complex interplay between individual, social, and health care systems and their influence on colonoscopy completion. The purpose of this study was to compare people who completed colonoscopy after receiving a referral with those who did not on demographic and clinical characteristics, CRC knowledge, and health beliefs (perceived risk, perceived benefits, perceived barriers). Quantitative data were collected via telephone interviews from 90 patients; 46 who completed colonoscopy and 44 non-completers. In-depth interviews were conducted with 42 participants to examine perceptions of barriers and facilitators to test completion. Data were analyzed using two-sample t-tests, chi-square tests, Fisher’s exact tests and content analysis. People who completed colonoscopy had a higher mean CRC knowledge score (p=.0008), and a smaller proportion had hypertension (p=.03). No group differences in perceived risk (p=0.81), perceived benefits (p=0.66), and perceived barriers scores (p=0.24) were observed. Non-completers frequently reported that life events interfered with their ability to keep their appointments. While receipt of a provider recommendation is the most important predictor of CRC screening, results showed that receipt of a recommendation with immediate referral to an endoscopist and automatic colonoscopy appointment-making were not sufficient to insure test completion. Education and tailored counseling about the need for and benefits of colonoscopy, along with reminders and tangible assistance to complete the test in the context of competing demands, may be required to increase completion rates.Item Process Evaluation of a Mailed Interactive Educational DVD in a Comparative Effectiveness Trial to Promote Colorectal Cancer Screening(Sage, 2022) Katz, Mira L.; Emerson, Brent; Champion, Victoria L.; Schwartz, Peter H.; Impleriale, Thomas F.; Fatima, Hala; Paskett, Electra D.; Perkins, Susan M.; Tong, Yan; Gebregziabher, Netsanet; Krier, Connie; Tharp, Kevin; Malloy, Caeli; Strom, Sylvia; Rawl, Susan M.; School of NursingA process evaluation was conducted as part of a comparative effectiveness trial of a mailed interactive educational DVD intervention to promote colorectal cancer screening among average-risk patients who did not attend a scheduled colonoscopy. Participants (n = 371) for the trial were randomized to (1) mailed DVD, (2) mailed DVD plus patient navigation, or (3) usual care. Participants (n = 243) randomized to the two DVD intervention arms were called 2 weeks after mailing materials to complete a process evaluation interview about the DVD (September 2017-February 2020). Forty-nine (20%) participants were not reached, and 194 (80%) participants watched the DVD and completed the interview. The process evaluation assessed whether (1) the DVD content was helpful, (2) any new information was learned by participants, (3) the appropriate amount of information was included in the DVD, (4) participants were engaged when watching the DVD, (5) the DVD content was relevant, (6) participants were satisfied with the DVD (7) participants would recommend the DVD to others, and (8) their opinion about colorectal cancer screening was changed by watching the DVD. Among participants who watched the DVD, 99% reported the screening information was very or somewhat helpful, 47% learned new information, 75% said the DVD included the right amount of information, they were engaged (M = 3.35 out of 4, SD = 0.49), 87% reported all or most information applied to them, they were satisfied (M = 3.42 out of 4, SD = 0.39) with DVD content, 99% would recommend the DVD to others, and 45% reported changing their opinion about screening. To understand the effects of interventions being tested in trials and to plan the dissemination of evidence-based interventions, process evaluation is critical to assess the dose received and acceptability of behavioral interventions.Item Promoting Colorectal Cancer Screening Discussion: A Randomized Controlled Trial(2013-04) Christy, Shannon M.; Perkins, Susan M.; Tong, Yan; Krier, Connie; Champion, Victoria L.; Skinner, Celette Sugg; Springston, Jeffrey K.; Imperiale, Thomas F.; Rawl, Susan M.Background Provider recommendation is a predictor of colorectal cancer (CRC) screening. Purpose To compare the effects of two clinic-based interventions on patient–provider discussions about CRC screening. Design Two-group RCT with data collected at baseline and 1 week post-intervention. Setting/participants African-American patients that were non-adherent to CRC screening recommendations (n=693) with a primary care visit between 2008 and 2010 in one of 11 urban primary care clinics. Intervention Participants received either a computer-delivered tailored CRC screening intervention or a nontailored informational brochure about CRC screening immediately prior to their primary care visit. Main outcome measures Between-group differences in odds of having had a CRC screening discussion about a colon test, with and without adjusting for demographic, clinic, health literacy, health belief, and social support variables, were examined as predictors of a CRC screening discussion using logistic regression. Intervention effects on CRC screening test order by PCPs were examined using logistic regression. Analyses were conducted in 2011 and 2012. Results Compared to the brochure group, greater proportions of those in the computer-delivered tailored intervention group reported having had a discussion with their provider about CRC screening (63% vs 48%, OR=1.81, p<0.001). Predictors of a discussion about CRC screening included computer group participation, younger age, reason for visit, being unmarried, colonoscopy self-efficacy, and family member/friend recommendation (all p-values <0.05). Conclusions The computer-delivered tailored intervention was more effective than a nontailored brochure at stimulating patient–provider discussions about CRC screening. Those who received the computer-delivered intervention also were more likely to have a CRC screening test (fecal occult blood test or colonoscopy) ordered by their PCP.
