Comparative effectiveness of five fecal immunochemical tests using colonoscopy as the gold standard: study protocol. Contemp Clin Trials 2021; 106:106430. [PMID: 33974994 DOI: 10.1016/j.cct.2021.106430] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 04/26/2021] [Accepted: 05/04/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND There are nearly 50,000 colorectal cancer (CRC) deaths in the United States each year. CRC is curable if detected in its early stages. Fecal immunochemical tests (FITs) can detect precursor lesions and many can be analyzed at the point-of-care (POC) in physician offices. However, there are few data to guide test selection. Broader use of FITs could make CRC screening more accessible, especially in resource-poor settings. METHODS A total of 3600 racially and ethnically diverse individuals aged 50 to 85 years having either a screening or surveillance colonoscopy will be recruited. Each participant will complete five FITs on a single stool sample. Test characteristics for each FIT for advanced colorectal neoplasia (ACN) will be calculated using colonoscopy as the gold standard. RESULTS We have complete data from a total of 2990 individuals. Thirty percent are Latino and 5.3% are black/African American. We will present full results once the study is completed. CONCLUSIONS Our focus in this study is how well FITs detect ACN, using colonoscopy as the gold standard. Four of the five FITs being used are POC tests. Although FITs have been shown to have acceptable performance, there is little data to guide which ones have the best test characteristics and colonoscopy is the main CRC screening test used in the United States. Use of FITs will allow broader segments of the population to access CRC screening because these tests require no preparation, are inexpensive, and can be collected in the privacy of one's home. Increasing CRC screening uptake will reduce the burden of advanced adenomas and colorectal cancer.

Abstract
Medical and health science graduate students report greater anxiety problems than the general population, but they are less likely to seek treatment due to cultural and logistical barriers. One preventative approach that overcomes these barriers is web-based cognitive behavioral therapy (webCBT). It is unknown whether webCBT is effective for preventing anxiety escalation within this population. A randomized controlled trial was conducted, comparing the effects of webCBT versus a control group (CG). Medical university students (n=594; Mage=27; 67% female; 80% Caucasian) completed online baseline measures and four assigned online activities. Measures were re-administered after approximately three months. There was a small interaction effect between time of assessment and treatment condition. Anxiety severity was lower in the webCBT (M[SD]=2.88[3.36]) versus CG condition (M[SD]=3.69 [3.35]) at follow-up. This effect was moderate for students with mild, versus minimal, anxiety at baseline. The proportion of students with possible anxiety disorder was lower in the webCBT (4.5%) versus CG (8.5%) condition, and the proportion of mildly anxious students with a clinically significant increase in symptoms was lower in the webCBT (10%) versus CG (20%) condition. WebCBT may aid in preventing anxiety escalation in this population, particularly for at-risk students who report mild anxiety symptoms.

Abstract
Aim To measure the knowledge, perceptions, and practices of Jordanian primary healthcare practitioners (PHCPs) (physicians, nurses, midwives, and nurse aids) employed in Jordanian Ministry of Health (MoH) primary health clinics with respect to counseling on cancer (cancer screening, the signs and symptoms of cancer, and referral for specialized care). BACKGROUND Integration of oncology services within primary care is a means of enhancing cancer early detection, and requires involvement of skilled. In the Middle East, little is known about PHCPs' potential to be providers of such services. METHODS A questionnaire measuring PHCP perceptions and practices related to counseling on cancer screening and diagnosis was distributed to PHCPs across MoH clinics covering the main regions of Jordan. Findings A total of 322 practitioners responded (75.1% response). Across most activities involving cancer detection, no more than 30% reported performing activities. Roughly half of PHCPs expressed discomfort at providing cancer-related counseling and at least 43% of non-physicians expressed limited confidence in cancer-related counseling. Confidence was a consistent predictor of provision of counseling and confidence in turn was associated with having greater knowledge, having positive a valuation of counseling, and being a physician. Results reveal points where educational efforts can strengthen PHCPs' provision of cancer control-related services.

Abstract
Objectives. We assessed the protocols and system processes for colorectal cancer (CRC) screening at federally qualified health centers (FQHCs) in 4 midwestern states. Methods. We identified 49 FQHCs in 4 states. In January 2013, we mailed their medical directors a 49-item questionnaire about policies on CRC screening, use of electronic medical records, types of CRC screening recommended, clinic tracking systems, referrals for colonoscopy, and barriers to providing CRC. Results. Forty-four questionnaires (90%) were returned. Thirty-three of the respondents (75%) estimated the proportion of their patients up-to-date with CRC screening, with a mean of 35%. One major barrier to screening was inability to provide colonoscopy for patients with a positive fecal occult blood test (59%). The correlation of system strategies and estimated percentage of patients up-to-date with CRC screening was 0.43 (P = .01). Conclusions. CRC system strategies were associated with higher CRC screening rates. Implementing system strategies for CRC screening takes time and effort and is important to maintain, to help prevent, or to cure many cases of CRC, the second leading cause of cancer in the United States.

Abstract
BACKGROUND Shared decision making (SDM) related to test preference has been advocated as a potentially effective strategy for increasing adherence to colorectal cancer (CRC) screening, yet primary care providers (PCPs) are often reluctant to comply with patient preferences if they differ from their own. Risk stratification advanced colorectal neoplasia (ACN) provides a rational strategy for reconciling these differences. OBJECTIVE To assess the importance of risk stratification in PCP decision making related to test preference for average-risk patients and receptivity to use of an electronic risk assessment tool for ACN to facilitate SDM. DESIGN Mixed methods, including qualitative key informant interviews and a cross-sectional survey. PARTICIPANTS PCPs at an urban, academic safety-net institution. MAIN MEASURES Screening preferences, factors influencing patient recommendations and receptivity to use of a risk stratification tool. KEY RESULTS Nine PCPs participated in interviews and 57 completed the survey. Despite an overwhelming preference for colonoscopy by 95% of respondents, patient risk (67%) and patient preferences (63%) were more influential in their decision making than patient comorbidities (31%; P < 0.001). Age was the single most influential risk factor (excluding family history), with <20% of respondents choosing factors other than age. Most respondents reported that they would be likely to use a risk stratification tool in their practice either 'often' (43%) or sometimes (53%). CONCLUSIONS Risk stratification was perceived to be important in clinical decision making, yet few providers considered risk factors other than age for average-risk patients. Providers were receptive to the use of a risk assessment tool for ACN when recommending an appropriate screening test for select patients.

Abstract
OBJECTIVE To implement a colon cancer screening program for uninsured or underinsured Iowans. METHODS All 1995 uninsured patients or patients with Iowa Care insurance aged 50 to 64 years attending the University of Iowa Clinic or the Iowa City Free Medical Clinic were mailed information about the project. Recruitment also took place in person, by having the clinic receptionist hand subjects a research packet, and through community posters. Individuals with colonic symptoms or who were up to date with screening were ineligible. Eligible subjects received a free fecal immunochemical test (FIT), and those with positive FITs were provided with a colonoscopy at no cost to them. RESULTS Of 449 individuals who completed eligibility forms (23% of the study population), 297 (66%) were eligible and were provided with an FIT. Two-hundred thirty-five (79%) returned a stool sample, with 49 (21%) testing positive. Thirty of the 49 (61%) individuals had a colonoscopy, and 20 individuals had at least 1 polyp biopsied. Thirteen individuals had at least 1 tubular adenoma; 2 had adenomas more than 1 cm in diameter, with no colon cancers identified. Face-to-face recruitment had the highest rate of returned FITs (72%) compared with handing the subject a research packet (3%) or a mailing only (9%) (Chi-square, P < .001). CONCLUSION There was high interest in and compliance with colon cancer screening using a FIT among underinsured individuals. Although the FIT positivity rate was higher than expected, many individuals did not complete recommended follow-up colonoscopies. Population-based strategies for offering FIT could significantly increase colon cancer screening among disadvantaged individuals, but programs will have to develop sustainable mechanisms to include the necessary organization and address substantial costs of providing mass screening, as well as facilitating and providing colonoscopies for those who test positive.

Abstract
BACKGROUND Studies have demonstrated that physician/pharmacist collaboration can improve management of chronic conditions. OBJECTIVE The purpose of this study was to determine whether a correlation exists between existing clinical pharmacy services within a practice-based research network (PBRN) and provider attitudes and beliefs regarding implementing a new pharmacy intervention based on the Theory of Planned Behavior (TPB). METHODS A validated survey was completed by one clinical pharmacist from each office. This instrument evaluated the current clinical pharmacy services provided in the medical office. TPB instruments were developed that measured beliefs concerning implementation of a clinical pharmacy intervention for either blood pressure or asthma. The pharmacy services and TPB surveys were then administered to physicians and pharmacists in 32 primary care offices throughout the United States. RESULTS Physicians returned 321 (35.9%) surveys, while pharmacists returned 40 (75.5%). The Cronbach's alpha coefficients generally ranged from 0.65 to 0.98. TPB subscale scores were lower in offices rated with lower pharmacy service scores, but these differences were not statistically significant. There was no correlation between clinical pharmacy service score and providers' TPB subscale scores. In both the hypertension and asthma groups, pharmacists scores were significantly higher than physicians' scores on the attitudes subscale in the multivariate analysis (P < 0.001 and P < 0.05, respectively). CONCLUSIONS Pharmacists consistently scored higher than physicians on the TPB, indicating that they felt the hypertension or asthma intervention would be more straightforward for them to implement than did physicians. There was no significant correlation between clinical pharmacy service scores and attitudes toward implementing a future physician/pharmacist collaborative intervention using the TPB. Future studies should investigate the ability of the TPB instrument to predict implementation of a similar intervention in offices of physicians never exposed to clinical pharmacy services.

Abstract
Patients generally access colorectal cancer (CRC) screening through primary care physicians. National guidelines recommend CRC screening for adults beginning at age 50, yet one-third of Americans are not up to date. Methods: A self-administered questionnaire was administered to family physicians from 16 practices in a Midwestern state who attended an information session for a randomized study to improve CRC screening. The questionnaire assessed CRC screening practices, knowledge of CRC screening guidelines, and office strategies for improving screening. Results: Of 131 health care providers, 85 (65%) completed the questionnaire. Two-thirds were aware of the CRC screening guidelines; 91% knew that the follow-up interval for screening depends on the test chosen. Twenty-five percent incorrectly stated that a single-sample in-office fecal occult blood test is an acceptable screening test. Only 8% had a written policy regarding CRC screening; 18% had offices that used chart reminders; and 32% had charts organized to easily identify patient screening status. Regarding perceptions, those who agreed that they encourage their office staff to participate in screening estimated that they offer screening to more patients than those who disagreed (82.8% vs 70.2%, P < .0001); in addition, those who agreed with and tried to follow the guidelines estimated that they offer screening to more patients than those who disagreed (77.4% vs 60.5%, P = .004). Conclusion: Although physicians were knowledgeable about CRC screening guidelines, 25% mistakenly believed that single-sample in-office fecal testing was appropriate. There was a striking lack of office systems for identifying eligible patients and facilitating CRC screening.

Abstract
Various interventions have been implemented to increase the rate of colon cancer screening. The purpose of this study was to determine if persons who are regular patients of a clinic, ages 50-64 years, and not up-to-date with colon cancer screening will complete the at-home fecal-immunochemical test (FIT) if it is mailed to them. This intervention was designed to have the subject avoid the signing of an informed consent and having to ask for the screening test; and, only one stool specimen was needed. Three hundred and fifty potential subjects were randomly selected from an electronic medical record database after meeting inclusion criteria. Eighty-seven fecal immunochemical tests were returned. Seven of the FIT kit results were positive for occult blood. Each respondent was sent a letter giving them their results. A minimal cue CRC screening intervention, a FIT kit sent in the mail without prerequisite of a signed informed consent, was offered to the study subjects. Twenty-six percent of the eligible persons were screened for colon cancer by this method. A mailed FIT kit or one handed to the patient at an office visit has minimal cost which can be recovered through insurance coverage. Commitment by health care providers is necessary for prevention. This method is one of several that could reach the hard to screen population.

Abstract
PURPOSE Colorectal cancer (CRC) screening remains underutilized. The objective of this study was to examine the impact of primary care and economic barriers to health care on CRC testing relative to the 2001 Medicare expansion of screening coverage. METHODS Medicare Current Beneficiary Survey data were use to study community-dwelling enrollees aged 65 to 80 years, free of renal disease and CRC, and who participated in the survey in 2000 (n = 8,330), 2003 (n = 7,889), or 2005 (n = 7,614). Three outcomes were examined: colonoscopy/sigmoidoscopy within 5 years (recent endoscopy), endoscopy more than 5 years previously, and fecal occult blood test (FOBT) within 2 years. RESULTS Endoscopy use increased and FOBT use decreased during the 6-year period, with no significant independent differences between those receiving care from primary care physicians and those receiving care from other physicians. Beneficiaries without a usual place of health care were the least likely to undergo CRC testing, and that gap widened with time: adjusted odds ratio (AOR) = 0.27 (95% confidence interval [CI], 0.19-0.39) for FOBT, and AOR = 0.35 (95% CI, 0.27-0.46) for endoscopy in 2000 compared with AOR = 0.18 (95% CI, 0.11-0.30) for FOBT and AOR = 0.22 (95% CI, 0.17-0.30) for endoscopy in 2005. Disparities in use of recent endoscopy by type of health insurance coverage in both 2000 and 2005 were greater for enrollees with a high school education or higher than they were for less-educated enrollees. There were no statistically significant differences by delayed care due to cost after adjustment for health insurance. CONCLUSION Despite expanding coverage for screening, complex CRC screening disparities persisted based on differences in the usual place and cost of health care, type of health insurance coverage, and level of education.
