Screening for colorectal cancer in a safety-net health care system: access to care is critical and has implications for screening policy.

ABSTRACT: BACKGROUND:Data on the number of individuals eligible for screening, and rates of screening, are necessary to assess national colorectal cancer screening efforts. Such data are sparse for safety-net health systems. METHODS:A retrospective cohort study of individuals ages 50 to 75 served by a safety-net health system in Tarrant County, TX was conducted to determine (a) the size of the potential screen-eligible population ages 50 to 75, (b) the rate of screening over 5 years among individuals ages 54 to 75, and (c) the potential predictors of screening, including sex, race/ethnicity, insurance status, frequency of outpatient visits, and socioeconomic status. RESULTS:Of 28,708 potential screen-eligible individuals, 20,416 were ages 54 to 75 and analyzed for screening; 22.0% were screened within the preceding 5 years. Female gender, Hispanic ethnicity, ages 65 to 75, insurance status, and two or more outpatient visits were independently associated with screening. Access to care was an important factor: adjusted odds ratio, 2.57 (95% confidence interval, 2.23-2.98) for any insurance; adjusted odds ratio, 3.53 (95% confidence interval, 3.15-3.97) for two or more outpatient visits. CONCLUSIONS:The screen-eligible population served by our safety-net health system was large, and the projected deficit in screen rates was substantial. Access to care was the dominant predictor of screening participation. If our results are replicable in similar health systems, the data suggest that screening guidelines and policy efforts must take into account the feasibility of proposed interventions. Strong advocacy for more resources for colorectal cancer screening interventions (including research into the best manner to provide screening for large populations) is needed.

Project description:Massachusetts' health care reform substantially decreased the percentage of uninsured residents. However, less is known about how reform affected access to care, especially according to insurance type.To assess access to care in Massachusetts after implementation of health care reform, based on insurance status and type.We surveyed a convenience sample of 431 patients presenting to the Emergency Department of Massachusetts' second largest safety net hospital between July 25, 2009 and March 20, 2010.Demographic and clinical characteristics, insurance coverage, measures of access to care and cost-related barriers to care.Patients with Commonwealth Care and Medicaid, the two forms of insurance most often newly-acquired under the reform, reported similar or higher utilization of and access to outpatient visits and rates of having a usual source of care, compared with the privately insured. Compared with the privately insured, a significantly higher proportion of patients with Medicaid or Commonwealth Care Type 1 (minimal cost sharing) reported delaying or not getting dental care (42.2 % vs. 27.1 %) or medication (30.0 % vs. 7.0 %) due to cost; those with Medicaid also experienced cost-related barriers to seeing a specialist (14.6 % vs. 3.5 %) or getting recommended tests (15.6 % vs. 5.9 %). Those with Commonwealth Care Types 2 and 3 (greater cost sharing) reported significantly more cost-related barriers to obtaining care than the privately insured (45.0 % vs. 16.0 %), to seeing a primary care doctor (25.0 % vs. 6.0 %) or dental provider (58.3 % vs. 27.1 %), and to obtaining medication (20.8 % vs. 7.0 %). No differences in cost-related barriers to preventive care were found between the privately and publicly insured.Access to care improved less than access to insurance following Massachusetts' health care reform. Many newly insured residents obtained Medicaid or state subsidized private insurance; cost-related barriers to access were worse for these patients than for the privately insured.

Project description:Low-income and racial/ethnic minority populations experience disproportionate colorectal cancer (CRC) burden and poorer survival. Novel behavioral strategies are needed to improve screening rates in these groups.The study aimed to test a theoretically based "implementation intentions" intervention for improving CRC screening among unscreened adults in urban safety-net clinics.Randomized controlled trial.Adults (N=470) aged ?50 years, due for CRC screening, from urban safety-net clinics were recruited.The intervention (conducted in 2009-2011) was delivered via touchscreen computers that tailored informational messages to decisional stage and screening barriers. The computer then randomized participants to generic health information on diet and exercise (Comparison group) or "implementation intentions" questions and planning (Experimental group) specific to the CRC screening test chosen (fecal immunochemical test or colonoscopy).The primary study outcome was completion of CRC screening at 26 weeks based on test reports (analysis conducted in 2012-2013).The study population had a mean age of 57 years and was 42% non-Hispanic African American, 28% non-Hispanic white, and 27% Hispanic. Those receiving the implementation intentions-based intervention had higher odds (AOR=1.83, 95% CI=1.23, 2.73) of completing CRC screening than the Comparison group. Those with higher self-efficacy for screening (AOR=1.57, 95% CI=1.03, 2.39), history of asthma (AOR=2.20, 95% CI=1.26, 3.84), no history of diabetes (AOR=1.86, 95% CI=1.21, 2.86), and reporting they had never heard that "cutting on cancer" makes it spread (AOR=1.78, 95% CI=1.16, 2.72) were more likely to complete CRC screening.The results of this study suggest that programs incorporating an implementation intentions approach can contribute to successful completion of CRC screening even among very low-income and diverse primary care populations. Future initiatives to reduce CRC incidence and mortality disparities may be able to employ implementation intentions in large-scale efforts to encourage screening and prevention behaviors.

Project description:Introduction: Rates of diabetes/prediabetes continue to increase, with disparity populations disproportionately affected. Previous field trials promoted point-of-care (POC) glycemic screening in dental settings as an additional primary care setting to identify potentially at-risk individuals requiring integrated care intervention. The present study observed outcomes of POC hemoglobin A1c (HbA1c) screening at community health center (CHC) dental clinics (DC) and compliance with longitudinal integrated care management among at-risk patients attending dental appointments. Materials and Methods: POC HbA1c screening utilizing Food and Drug Administration (FDA)-approved instrumentation in DC settings and periodontal evaluation of at-risk dental patients with no prior diagnosis of diabetes/prediabetes and no glycemic testing in the preceding 6 months were undertaken. Screening of patients attending dental appointments from October 24, 2017, through September 24, 2018, was implemented at four Wisconsin CHC-DCs serving populations with a high representation of disparity. Subjects meeting at-risk profiles underwent POC HbA1c screening. Individuals with measures in the diabetic/prediabetic ranges were advised to seek further medical evaluation and were re-contacted after 3 months to document compliance. Longitudinal capture of glycemic measures in electronic health records for up to 2 years was undertaken for a subset (n = 44) of subjects with available clinical, medical, and dental data. Longitudinal glycemic status and frequency of medical and dental access for follow-up care were monitored. Results: Risk assessment identified 224/915 (24.5%) patients who met inclusion criteria following two levels of risk screening, with 127/224 (57%) qualifying for POC HbA1c screening. Among those tested, 62/127 (49%) exhibited hyperglycemic measures: 55 in the prediabetic range and seven in the diabetic range. Moderate-to-severe periodontitis was more prevalent in patients with prediabetes/diabetes than in individuals with measures in the normal range. Participant follow-up compliance at 3 months was 90%. Longitudinal follow-up documented high rates of consistent access (100 and 89%, respectively), to the integrated medical/DC environment over 24 months for individuals with hyperglycemic screening measures. Conclusion: POC glycemic screening revealed elevated HbA1c measures in nearly half of at-risk CHC-DC patients. Strong compliance with integrated medical/dental management over a 24-month interval was observed, documenting good patient receptivity to POC screening in the dental setting and compliance with integrated care follow-up by at-risk patients.

Project description:PurposeTo examine the activities, concerns, and expectations of critical care nurses and professional critical care nursing organizations worldwide.DesignA descriptive survey methodology was used. This study is the fifth worldwide quadrennial review of its type to monitor variations in critical care nursing needs and provide robust evidence to inform policy related to critical care nursing practice.MethodsThe fifth World Federation of Critical Care Nurses international survey of critical care nursing organizations was emailed to potential participants from countries with critical care nursing organizations or known critical care nurse leaders. Data were collected online. Responses were entered into SPSS version 23 software (IBM Corp., Armonk, NY, USA) and analyzed by geographical region and national wealth group.FindingsEighty-two national representative respondents participated in the survey, of whom two thirds (n = 56, 68%) had an established critical care nursing organization in their country. The five most important issues identified were working conditions, teamwork, staffing levels, the need for formal practice guidelines and competencies, and wages. The top five critical care nursing organization services that were considered to be of most importance were professional representation, as well as provision of workshops and education forums, national conferences, practice standards and guidelines, and local conferences. The most important contributions expected from the World Federation of Critical Care Nurses were standards for clinical practice and professional practice, international conferences, professional representation, and study and education grants.ConclusionsThe results highlight priority areas for critical care nursing and reinforce the need to address factors that can inform critical care nursing policy and practice. Results of this survey should be incorporated into strategic action plans at the national and international levels.Clinical relevanceNursing leaders, policymakers, and other interested stakeholders should consider these findings when planning critical care workforce requirements. Interested parties should work collaboratively to inform recommendations for further policy and action.

Project description:BackgroundElectronic and internet-based tools for patient-provider communication are becoming the standard of care, but disparities exist in their adoption among patients. The reasons for these disparities are unclear, and few studies have looked at the potential communication technologies have to benefit vulnerable patient populations.ObjectiveTo characterize access to, interest in, and attitudes toward internet-based communication in an ethnically, economically, and linguistically diverse group of patients from a large urban safety net clinic network.DesignObservational, cross-sectional studyParticipantsAdult patients (? 18 years) in six resource-limited community clinics in the San Francisco Department of Public Health (SFDPH) MAIN MEASURES: Current email use, interest in communicating electronically with health care professionals, barriers to and facilitators of electronic health-related communication, and demographic data-all self-reported via survey.Key resultsSixty percent of patients used email, 71 % were interested in using electronic communication with health care providers, and 19 % reported currently using email informally with these providers for health care. Those already using any email were more likely to express interest in using it for health matters. Most patients agreed electronic communication would improve clinic efficiency and overall communication with clinicians.ConclusionsA significant majority of safety net patients currently use email, text messaging, and the internet, and they expressed an interest in using these tools for electronic communication with their medical providers. This interest is currently unmet within safety net clinics that do not offer a patient portal or secure messaging. Tools such as email encounters and electronic patient portals should be implemented and supported to a greater extent in resource-poor settings, but this will require tailoring these tools to patients' language, literacy level, and experience with communication technology.

Project description:Chinese translationBlack persons are more likely than white persons to be diagnosed with colorectal cancer and to die from it. The extent to which genetic or biological factors versus disparities in screening rates explain this variance remains controversial.To define the prevalence and location of presymptomatic advanced colorectal neoplasia (ACN) among white and black persons undergoing screening colonoscopy, controlling for other epidemiologic risk factors.Cross-sectional survey between 22 March 2005 and 31 January 2012.Urban, open-access, academic, safety-net hospital in Massachusetts.Asymptomatic, average-risk white (n = 1172) and black (n = 1681) persons aged 50 to 79 years undergoing screening colonoscopy.Adjusted prevalence and location of ACN, defined as a tubular adenoma 10 mm or more in size, any adenoma with villous features or high-grade dysplasia, any dysplastic serrated lesion, or invasive cancer.The prevalence of ACN was higher among white patients than black patients (6.8% vs. 5.0%; P = 0.039) but varied by sex (white vs. black men, 9.3% vs. 5.7%; white vs. black women, 3.5% vs. 4.3%; interaction P = 0.034). After controlling for many risk factors, black men were 41% less likely than white men (adjusted odds ratio [AOR], 0.59 [95% CI, 0.39 to 0.89]) to have ACN. No statistically significant difference was seen for women (AOR, 1.32 [CI, 0.73 to 2.40]). Black patients with ACN had a higher percentage of proximal disease (52% vs. 39%) after adjustment for age and sex (P = 0.055).Single-institution study with inadequate statistical power for subgroup analyses and recall bias.Black men are less likely than white men to have ACN at screening colonoscopy in a safety-net health care setting. Disparities in access to screening and differential exposure to modifiable risk factors rather than genetic or biological factors may be largely responsible for the higher incidence of CRC among black men. Genetic or biological factors may explain the predilection for proximal disease.

Project description:IntroductionCritical care physicians may benefit from immediate access to medical reference material. We evaluated the feasibility and potential benefits of a handheld computer based knowledge access system linking a central academic intensive care unit (ICU) to multiple community-based ICUs.MethodsFour community hospital ICUs with 17 physicians participated in this prospective interventional study. Following training in the use of an internet-linked, updateable handheld computer knowledge access system, the physicians used the handheld devices in their clinical environment for a 12-month intervention period. Feasibility of the system was evaluated by tracking use of the handheld computer and by conducting surveys and focus group discussions. Before and after the intervention period, participants underwent simulated patient care scenarios designed to evaluate the information sources they accessed, as well as the speed and quality of their decision making. Participants generated admission orders during each scenario, which were scored by blinded evaluators.ResultsTen physicians (59%) used the system regularly, predominantly for nonmedical applications (median 32.8/month, interquartile range [IQR] 28.3-126.8), with medical software accessed less often (median 9/month, IQR 3.7-13.7). Eight out of 13 physicians (62%) who completed the final scenarios chose to use the handheld computer for information access. The median time to access information on the handheld handheld computer was 19 s (IQR 15-40 s). This group exhibited a significant improvement in admission order score as compared with those who used other resources (P = 0.018). Benefits and barriers to use of this technology were identified.ConclusionAn updateable handheld computer system is feasible as a means of point-of-care access to medical reference material and may improve clinical decision making. However, during the study, acceptance of the system was variable. Improved training and new technology may overcome some of the barriers we identified.
