Iowa family physician's reporting of elder abuse: 20-year follow-up

The purpose of this project was to assess changes over 20 years, between family physicians perceived magnitude of elder mistreatment, physician knowledge of state laws, barriers to reporting suspected cases, and what is done in practice. Questionnaires were mailed to 1,080 physician members of the Iowa Academy of Family Physicians. Thirty-six percent of physicians returned the questionnaire. These respondents had a mean age of 51 years, were licensed for 19 years, and 51% were male. Twenty-nine percent of physicians ask their patients direct questions about elder abuse in 2022 compared to 14% in 2002. Identifying an elder abuse case was associated with asking direct questions about abuse and the belief that prompt action would be taken. Knowledge of elder abuse legislation was associated with reporting of all abuse cases, along with thinking there were clear definitions of abuse and that reporting benefits patients.

Personal and Professional Physical Activity Practices among Sports Medicine Physicians

ABSTRACT

Less than a quarter of the population achieves the recommended Physical Activity Guidelines for Americans. Physicians who achieve the guidelines themselves may be more likely to promote them to patients given strong evidence physicians' personal health habits influence their patient counseling practices. We surveyed primary care and sports medicine specialty physicians about personal exercise habits and beliefs and patient counseling practices. Sports medicine physicians were significantly more likely to meet the Physical Activity Guidelines for Americans and believe that as physicians, they have an obligation to do so. They also were more likely to ask about, counsel, and refer patients to physical activity resources than other primary care physicians. Our results are consistent with previous evidence that physicians' personal habits influence their practice recommendations. This provides support that physicians' personal beliefs about the importance of exercise and sense of obligation to achieve recommended levels themselves plays a strong role in their patient care practices.

Challenges in Use of Practice-based Research Networks for a Medical Device Trial to Detect SARS-CoV-2

INTRODUCTION/OBJECTIVES

Primary care practice-based research networks (PBRNs) participated in a point of care (POC) device study funded by by the National Institutes of Health and led by the University of Massachusetts Chan Medical School (UMass) to speed the development, validation, and commercialization of POC tests to detect SARS-CoV-2. The purposes of this study were to describe the characteristics of participating PBRNs and their respective collaborators in this device trial and describe complications challenging its execution.

METHODS

Semi-structured interviews were conducted with lead personnel from participating PBRNs and UMass.

RESULTS

Four PBRNs and UMass were invited to participate and 3 PBRNs and UMass participated. This device trial recruited 321 subjects in 6 months; 65 subjects from PBRNs. Each PBRN and the academic medical center site enrolled and recruited subjects differently. Main challenges identified were having adequate clinic personnel to enroll and aid in consent and questionnaire completion, frequently changing inclusion/exclusion criteria, use of the digital electronic data collection platform, and having access to a -80°C freezer to store supplies.

DISCUSSION

This trial involved numerous researchers, primary care clinic leaders and staff, and academic center sponsored program staff and attorneys resulting in a resource-intensive endeavor to enroll 65 subjects in the real-world clinical setting of primary care PBRNs with the academic medical center enrolling the rest. Multiple obstacles to standing up the study were encountered by the PBRNS.

CONCLUSIONS

Primary care PBRNs rely largely on the goodwill established between academic health centers and participating practices. For future investigations involving device studies, collaborating PBRN leaders should assess whether recruitment criteria may change, obtain detailed lists of equipment needed, and/or know if the study is likely to be halted suddenly to appropriately prepare their member practices.

Clock-Drawing Test as a Screening Tool for Cognitive Impairment Associated With Fecal Immunochemical Test Collection Errors

PURPOSE

The purposes of this study were to determine if (1) certain demographic characteristics (potential predictors) of participants, and (2) clock-drawing test results (as a screening test for cognitive impairment) were associated with fecal immunochemical test (FIT) sample collection errors.

METHODS

Patients scheduled for an upcoming colonoscopy were asked to collect stool samples using 5 different FITs. Patients completed a questionnaire that included the clock-drawing test. Errors included mistakes or omissions in recording the stool collection date and errors in stool collection. Each clock drawing was scored by 2 reviewers using 2 established methods.

RESULTS

Of the 1,448 participants with a clock drawing, 63% were female with a mean age of 63 years. In this population there were 83% White, 6% Black, and 24% Hispanic persons. Cognitive impairment was found in 292 patients by the Mendes-Santos method. Kappa coefficient for the 2 clock-drawing scores was 0.79 (P <.001). The multivariable generalized linear mixed model for FIT collection errors indicated being female (adjusted odds ratio [AOR], 1.64; 95% CI, 1.09-2.48), having an 8th grade or less education (AOR, 3.40; 95% CI, 1.87-6.18), and having an abnormal Mendes-Santos method clock score (AOR, 1.65; 95% CI, 1.08-2.54) were associated with significantly more errors.

CONCLUSION

Among the participants who do not have dementia, FIT collection errors were made not only by those who had abnormal clock drawing, but also, by those with normal clock drawings. Subjects being female, having 8th grade education or less, and having an abnormal clock drawing scored by Mendes-Santos's method were associated with FIT collection errors.

Primary Caregiver Retention and Perceptions of Retention Strategies in a 36-Month Prospective Childhood Caries Study

Introduction/Objectives:

This paper reports on participant retention from an ongoing prospective, multi-site cohort caries risk study involving parent/infant pairs. The objectives were to: (1) compare the retention rates at each intermediate contact (every 4 months) and dental visit (every 18 months) across the 3 clinical sites, (2) assess primary caregivers’ perceptions at the end of the study about the retention efforts used in this longitudinal study, and (3) determine whether primary caregiver baseline demographic characteristics and child’s baseline caries experience were associated with retention.

Methods:

1325 primary caregiver-child pairs recruited at the child’s first birthday were followed for 36 months at 3 sites. Dental visits occurred at children’s ages of approximately 12, 30, and 48 months. Telephone/email intermediate contacts with the primary caregiver occurred 6 times between dental visits. The outcome variable was the retention rates at each dental visit and each intermediate contact. Primary caregivers’ perceptions of intermediate contacts were evaluated. Retention rates were compared by maternal age, race, ethnicity, Medicaid status, yearly household income, baseline caries experience (defined as decayed, missing due to caries, or filled tooth surfaces) at 12 months, and the number of teeth erupted.

Results:

1325 primary caregiver/infant pairs were enrolled and completed the first in-person dental visit, 1062 pairs (80%) completed the second visit and 985 (74%) completed the third. Most primary caregivers were female (94%), with a mean age of 29 years and 667 (50%) self-identified as White, 544 (41%) as Black, and 146 (11%) as Hispanic. The percentages of successful intermediate contacts were 95% at 4 months decreasing to 82% at 34 months. Almost all 964 (98%) of 985 primary caregivers reported at the last visit that they were comfortable/very comfortable with 4-month intermediate contacts. The multivariable analysis showed that primary caregivers who were older (OR = 1.07; 95% CI, 1.04-1.09) and White (OR = 1.52; 95% CI, 1.12-2.06) were more likely to complete the study.

Conclusions:

Retention strategies were focused on frequent routine contact and increasing monetary incentives. Those strategies may have resulted in retention exceeding the proposed goals. At the end of the study, primary caregivers were comfortable with the 4-month intermediate contacts.

Trained Clinician's Documentation of Serious Illness Conversations and Use of Billing CPT 99497

BACKGROUND

Advance care planning (ACP) involves patients and family members in discussions with clinicians about their values, goals, and preferences regarding future medical care. Objectives: To (1) assess whether an ACP conversation using the Serious Illness Conversation (SIC) was initiated and documented; (2) assess which components of SIC were documented; (3) determine how frequently clinicians trained to use the SIC guide used ACP billing codes during the study time period, (4) determine whether there was a significant difference in mortality risk score according to documentation of each component of the SIC. Methods; Thirteen clinicians at three family medicine offices were trained in the Serious Illness Care Program and asked to document SICs in the electronic medical record (EMR). A retrospective chart review of SIC components was conducted in the EMRs of patients who presumably had ACP conversations initiated by the trained clinicians. Patients were identified using the billing codes for ACP conversations and through referrals from another study that requires clinicians to have ACP conversations with their patients. Pearson chi-square test for categorical variables and t-tests for continuous variables were conducted. Results: A total of 157 patients were included in this study; 131 patients referred from another ACP study and an additional 26 patients using the billing codes of ACP conversations. Through retrospective chart review, the mean age of patients was 72 years and 54 were male. Sixty-two (40%) charts had one or more SIC components documented. "Explore key topics" was documented most frequently for 58 (38%) patients by the 13 participating clinicians. Mean mortality risk score was 10.7 and higher scores were significantly correlated with more SIC components documented (r_p = 0.217, P = 0.007). Conclusion: Little use of the SIC guide among trained physicians was found in the EMR. It was expected that provision of an EMR template for documenting the SIC would have facilitated documentation of SICs.

Tooth Eruption and Early Childhood Caries: A Multisite Longitudinal Study

Purpose: The purpose of this study was to assess the relationship between the number of teeth present at 12 months and decayed, missing, or filled surfaces (dmfs) at 30 and 48 months. Methods: Data are from a longitudinal, multisite study with clinical dental examinations conducted at 12, 30, and 48 months of age. Spearman correlation and chi-square tests assessed relationships between teeth present at 12 months and dmfs at 30 (n equals 1,062) and 48 months (n equals 985). Results: Spearman correlations were weak but significant for both 30- and 48-month time points (R equals 0.066, P=0.032; R equals 0.093, P=0.004, respectively). Mantel-Haenszel chi-square analyses of categories of teeth present at 12 months (zero, one to four, five to eight, and greater than or equal to nine) and categories of dmfs at 30 and 48 months (zero, one to two, three to five, six to 15, and greater than or equal to 16) revealed nonsignificant (P=0.326) relationship with 30-month dmfs but a significant (P=0.013) relationship with 48-month dmfs. Conclusion: Results suggest that early tooth eruption is weakly associated with an occurrence of early childhood caries.

Improving Iowa Research Network Patient Recruitment for an Advance Care Planning Study

INTRODUCTION/OBJECTIVES

In February 2019, recruitment began in Iowa Research Network offices for a Patient-Centered Outcomes Research Institute (PCORI) funded Advance Care Planning (ACP) study to be conducted in 7 primary care practice-based research networks across the United States and Canada. The main study trained clinicians and nursing staff in serious illness care conversations and requested they refer eligible patients. Eligible patients were those with serious illness or frailty expected to live 1 to 2 years. Clinicians indicated it was difficult to identify eligible patients. This study aimed to find better methods for increasing patient recruitment for the ACP study.

METHODS

Research staff brainstormed and implemented strategies to increase patient referrals from clinicians. Participating offices used Epic for their medical record and the Gagne Index was used to generate a list of eligible patients in Epic SlicerDicer. When patients from the Epic SlicerDicer report appeared on the schedule, clinicians and nursing staff were notified that they might be eligible for ACP. Clinicians and nursing staff were asked to complete a survey identifying their perception of implemented strategies. A Wilcoxon signed-rank test was conducted to compare referral numbers before and after the Gagne Index/Epic SlicerDicer intervention.

RESULTS

Seven clinicians referred patients prior to and 11 after the Gagne Index/Epic SlicerDicer intervention. Clinicians referred a total of 120 patients; 31 patients prior to and 89 patients after the Gagne Index/Epic SlicerDicer implementation (P = .002). Survey results indicated that several strategies facilitated clinician referrals, including patients identified as potentially appropriate on the schedule, quarterly meetings with researchers, and e-mails with a list of potentially eligible patients.

CONCLUSIONS

Notifying clinical staff about potential study participants increased patient referrals in this ACP study. Research staff must have time, funding, and patience to support clinical staff who are expected to refer patients to studies.

Impact of Medical Scribe Experiences on Subsequent Medical Student Learning

INTRODUCTION

Many US pre-health professional students prepare for applying to medical training by transcribing clinician-patient encounters. Scant literature of the effects of scribing experiences before starting medical training exists. We conducted a study to investigate student perspectives about medical scribing's educational impact on clinical skill development.

METHODS

Using a mixed-methods approach, medical and physician assistant students were surveyed and interviewed about clinical experiences and confidence before entering medical training, and the impact of scribing on clinical skills learning. Thematic analysis revealed salient themes in participants' perspectives on the scribing experience.

RESULTS

A total of 214 (33%) of the 658 students completed the survey; 66 (31%) had scribing experience. Scribes were more confident (p ≤ 0.001) in clinical note writing and history taking than non-scribes. Thematic analysis revealed perceptions that scribing impacted clinical note writing, medical knowledge, communication, and healthcare environment functioning.

DISCUSSION

Findings suggest that the scribing experience affects confidence and perceived skills, particularly clinical note writing. Future research could explore the impact on clinical skill development through comparative performance-based assessment.

CONCLUSION

Measuring the impact of scribing before entry to medical/physician assistant school on clinical skill development could provide directives for best approaches to clinical skills education in health professionals training.

Comparative effectiveness of five fecal immunochemical tests using colonoscopy as the gold standard: study protocol

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.

Changes in Parental Perceptions of Their Care of Their Children's Oral Health From Age 1 to 4 Years

Introduction: In this 3-year longitudinal study, parent/child attended 3 dental visits and in between, parents were called every 4 months and asked if their child had visited the dentist and if fluoride varnish had been applied. Methods: Objectives were to assess changes in parents’ perceptions of how well they do in taking care of their children’s teeth and/or gums across these 3 time points (at age 1, 2.5, and 4 years), assess differences in parents’ perceptions of how well they do taking care of their children’s teeth and/or gums versus taking care of their children’s medical health, and determine factors associated with parental perceptions of how well they do in taking care of the children’s teeth and/or gums longitudinally. Results: Participant pairs (1325) were enrolled and over time there was a significant improvement in parental perceptions of their job taking care of their children’s teeth and/or gums, increasing from 86% perceiving it to be excellent/very good/good at their child’s 1 year of age to 92% at child’s age 4 years. The estimated odds of parents perceiving they provided excellent/very good/good versus fair/poor care for the children’s teeth and/or gums were higher for those who cleaned and checked inside the children’s mouth and/or gums daily (odds ratio 4.74) or took their children to the dentist yearly or twice yearly (odds ratio; 2.73). Conclusions: Parents’ perceptions of the care of their children’s teeth and/or gums improved over time. Parents consistently perceived that they provided better medical care than dental care for their child.

Equine influenza vaccination as reported by horse owners and factors influencing their decision to vaccinate or not

BACKGROUND

Equine influenza virus is a highly contagious respiratory pathogen that causes pyrexia, anorexia, lethargy and coughing in immunologically naïve horses. Vaccines against equine influenza are available and vaccination is mandatory for horses that participate in affiliated competitions, but this group forms a small proportion of the total horse population. The aims of this study were to: i) identify the equine influenza vaccination rate as reported in 2016 by horse owners in the United Kingdom (UK); ii) examine the demographics of owners and horses which were associated with significantly lower influenza vaccination rates and iii) explore factors that influence horse owners' decisions around influenza vaccine uptake.

RESULTS

Responses from 4837 UK horse owners who were responsible for 10,501 horses were analysed. An overall equine influenza vaccination rate of 80% (8385/10501) was reported. Several owner demographic characteristics were associated with significantly lower (p<0.05) reported equine influenza vaccination rates including: some geographical locations, increasing horse owner age, annual household income of less that £15,000 and owning more than one horse. Horse-related features which were associated with significantly lower reported equine influenza vaccination rates included age ranges of <4 years and > 20 years, use as a companion or breeding animal or leaving their home premises either never or at most once a year. The most common reasons cited for failing to vaccinate horses was no competition activity, lack of exposure to influenza and expense of vaccines. In contrast, the most common underlying reasons given by horse owners who vaccinated their horse were protection of the individual horse against disease, veterinary advice and to protect the national herd. Owners of vaccinated horses had less previous experience of an influenza outbreak or adverse reaction to vaccination compared with owners of unvaccinated horses.

CONCLUSIONS

This study documented a high rate of equine influenza vaccination as reported by owners in a substantial number of horses in the UK, but this does not reflect the level of protection. Sub-populations of horses which were less likely to be vaccinated and the factors that influence each owner's decision around vaccination of their horses against equine influenza were identified, but may alter following the 2019 European influenza outbreak. This information may nevertheless help veterinary surgeons identify "at-risk" patients and communicate more personalised advice to their horse-owning clients. It may also influence educational campaigns about equine influenza directed to horse owners, which aim to improve uptake of vaccination against this pathogen.

Use of the Fluoride Varnish Billing Code in a Tertiary Care Center Setting

Introduction: Dental caries is the most common chronic disease in children from birth through 5 years of age. Application of fluoride varnish (FV) is recommended for children younger than 6 years every 3 to 6 months by the United States Preventive Services Task Force. The purposes of this study were to (1) assess use and reimbursement of Current Dental Terminology (CDT) D1206 and Current Procedural Terminology (CPT) 99188 codes, which are the billing codes for FV application; (2) determine when and by whom each FV code was used; and (3) summarize the associated clinical notes. Methods: Using the electronic medical record data warehouse from a single tertiary teaching hospital and its affiliated primary care clinics, the dates of service, departments, provider names, and patient identifiers associated with codes CDT D1206 and CPT 99188 were collected. The content of clinical notes was reviewed and summarized. The study period was from May 1, 2009 through May 17, 2019. Results: During the 10-year time period, CDT D1206 was used 5 times and CPT 99188 was used 35 times. FV was applied exclusively during well-child visits. Only pediatricians, and no family physicians, applied FV in this setting. Discussion: A single pediatrician championing for FV application increased both the completion of procedure and the appropriate billing in 2019. Conclusion: FV application has been likely underutilized in this Midwestern tertiary teaching hospital and its affiliated clinics. For both family medicine and pediatric offices, an advocate for caries prevention is likely needed for successful implementation of FV application at well-child visits.

Anxiety-Related Issues in Cancer Survivorship

PURPOSE

The purpose of this qualitative study was to examine patient opinions about anxiety in cancer survivorship, particularly the role of the primary care provider in management of anxiety related to the trajectory of long-term cancer survivorship.

METHODS

Respondents to a mass email (N=22,000) were invited to participate in 1 of 3 institutional review board-approved focus group meetings. Inclusion criteria were being an adult patient older than 25 years of age, having any type of cancer diagnosis, and being at least 18 months from treatment. The following specific issues were discussed: role of the primary care provider during and after therapy; the transition to primary care after therapy was finished; and advice the survivors would give to providers and cancer survivors. Focus group meetings were audio-recorded and later transcribed and reviewed by members of the research team using constant comparison methods.

RESULTS

Three 2-hour focus groups were conducted to interview 22 cancer survivors. We found 5 main themes related to anxiety in cancer survivorship: memory of anxiety; anxiety related to possible cancer recurrence; role of close relationship with the health care provider in anxiety management; frequency of communication in reduction of anxiety symptoms; and effect of anxiety on future health decisions posttreatment.

CONCLUSIONS

Survivors described anxiety persisting throughout cancer diagnosis and treatment and well into survivorship. They reported receiving care from primary care providers as well as oncologists. Anxiety was discussed by most participants as a significant part of their experience with cancer.

Diagnostic Performance of Four Fecal Immunochemical Tests for Detecting Advanced Colorectal Neoplasia: Preliminary Results

Screening programs based on fecal blood testing have been shown in randomized controlled trials to reduce colorectal cancer incidence and mortality. Professional organizations highly recommend screening average-risk patients with fecal immunochemical testing (FIT). Many patients find these stool tests more acceptable than colonoscopy and stool testing may be the preferred option for areas with limited endoscopic resources. However, the diagnostic performance of FIT testing, particularly for CLIA-waived point-of-care (POC) tests, has not been well studied. Purpose: We are comparing the diagnostic accuracy of 4 FIT tests, one automated (AUTO) and 3 POC, for detecting advanced neoplasia (advanced adenomas and carcinomas) using colonoscopy as a gold standard. Methods. We are enrolling subjects ages 50 to 85 at 3 academic medical centers in Iowa, Texas, and North Carolina who were scheduled for a screening or surveillance colonoscopy. Each subject completed 4 different FIT tests on a single stool specimen. Based on colonoscopy results, we calculated sensitivity, specificity, and predictive values. We used PROC GLIMMIX models in SAS to compare sensitivity and specificity across the different tests, accounting for the within-patient correlation. Results: We currently have 641 subjects who completed FIT and colonoscopy. Mean age is 61.2 (±7.5) years, 63% women, 63% non-Hispanic white, and 31% Hispanic. We found advanced neoplasia, including 5 carcinomas, in 68 subjects. The sensitivities for detecting these neoplasia were 3%, 22%, 28%, and 16% (AUTO), respectively. Corresponding positive predictive values were 18%, 21%, 33%, and 24% (AUTO). Specificities were 97%, 89%, 90%, and 94% (AUTO), respectively, and corresponding negative predictive values were 89%, 91%, 92%, and 90% (AUTO). We found statistically significant differences in sensitivity (P &lt; 0.01) and specificity (P &lt; 0.01) across tests. Conclusions: Early data suggest that FIT products may vary in their sensitivity and specificity for detecting advanced colorectal neoplasia. This variability could have important impacts on the effectiveness of efforts to limit the burden of colorectal cancer by increasing population-based screening rates through fecal blood testing.

A Needs Assessment of Family Physicians to Inform Development of Educational Resources on Antipsychotic Use in Dementia

OBJECTIVES

Objectives of this study were to (1) assess the needs and preferred resources of Iowa physicians to inform the development of educational resources for best practice dementia care and (2) compare the responses of nursing home medical directors with nonmedical directors.

METHODS

Of 498 physicians, 101 (20%) completed and returned the survey. Family physicians were obtained from a list of family physicians from the Iowa Board of Medical Examiners. Respondent answers were summarized and presented as total numbers and percentages in tables. Significant differences between medical directors and nonmedical directors were evaluated using chi-square tests, Fisher exact tests, and Wilcoxon rank-sum tests.

RESULTS

Medical directors and nonmedical directors had similar preferences for resources used and information needs. Online resources, pocket guides, a handbook, consulting pharmacists, and facility in-services were the most commonly preferred sources of new information. Medical directors were significantly more aware of the Food and Drug Administration warning on antipsychotic use in dementia and treated more nursing home patients. No differences were observed between groups related to confidence in and use of nondrug strategies instead of antipsychotics to manage behavioral symptoms of dementia.

CONCLUSION

The results of this survey illustrate physician preferences for information and resources on the management of behavioral and psychological symptoms in dementia. Information was used to inform the development of resources to aid physicians and other health care providers in making decisions about managing these symptoms.

Adapting Boot Camp Translation Methods to Engage Clinician/Patient Research Teams Within Practice-Based Research Networks: A Report From the INSTTEPP Trial and Meta-LARC Consortium

PURPOSE

Boot camp translation is a proven process to engage community members and health professionals in translating and disseminating evidence-based "best practices" models for health prevention and chronic illness care. Primary care practice improvement studies, particularly involving patient-driven change, as seen with self-management support (SMS), require engaged practice teams that include patients. Models of engagement such as boot camp translation may be effective.

METHODS

Four geographically dispersed practice-based research networks (PBRNs) from the Meta-LARC consortium engaged 16 practices to form SMS implementation teams involving a clinician, care manager, and 2 patients in each team. Our study adapted the boot camp translation model to engage the implementation teams in describing patient SMS, studying the Agency for Healthcare Research and Quality's SMS Resource Library, and adapting and implementing self-management tools at each practice site. Testimonials and quotes were collected across the 4 PBRNs through a facilitated brainstorming discussion and consensus model at each PBRN kickoff meeting to address the focused question, "What do patients want and need in order to self-manage their chronic illnesses?"

RESULTS

Testimonials collected across the 4 PBRNs and participation levels indicated there was a high degree of engagement in the boot camp translation process across the PBRNs and the practices. Each PBRN developed themes expressed by patients and the practices regarding what patients want and need to self-manage their illnesses. Each practice selected, adapted, and implemented an SMS tool.

CONCLUSIONS

Results suggest that adapted boot camp translation was effective in guiding multiple practices to implement self-management support tools for the INSTTEPP trial. Additional study of the adapted boot camp translation process in practice quality improvement and practice redesign studies is needed.

Impact of a Boot Camp Translation Intervention on Self-Management Support in Primary Care: A Report From the INSTTEPP Trial and Meta-LARC Consortium

PURPOSE

Self-management support (SMS) is a pillar of the well-established chronic care model and a key component of improving outcomes for patients with chronic illnesses. The Implementing Networks' Self-management Tools Through Engaging Patients and Practices (INSTTEPP) trial sought to determine whether a boot camp translation process could assist small to medium-sized primary care practices with care managers implement SMS tools.

METHODS

INSTTEPP used a stepped-wedge design across 16 practices from 4 practice-based research networks over 12 months. Each network completed a 2-month boot camp translation for creating SMS tools with 16 participants (2 patients, a clinician, and a care manager from each of 4 practices) and subsequent implementation. Outcome measures for patients were the Patient Activation Measure (PAM), self-rated health, and Patient Assessment of Chronic Illness Care (PACIC) process-of-care items at baseline, 1 and 2 months. Clinician Support for Patient Activation Measure (CS-PAM) and theory of planned behavior outcomes were assessed at 5 points over 10 months for clinicians and staff.

RESULTS

A total of 297 patients and 89 practice staff and clinicians completed surveys during the study. Over successive 2-month sampling periods, intervention patients experienced greater improvement in PACIC process of care and self-rated health compared to control patients (P<0.0001 and P=0.0273, respectively). PAM (P=0.3515), CS-PAM (P=0.7464), and theory of planned behavior outcomes (P>0.10 for all) were not significantly different.

CONCLUSIONS

Significant effects on process of care and self-rated health are evidence that the boot camp translation intervention impacted SMS. A larger trial with a typical 6-month boot camp intervention may show significant effects on other outcomes.

Implementing Community-Created Self-Management Support Tools in Primary Care Practices: Multimethod Analysis From the INSTTEPP Study

PURPOSE

With one-half of Americans projected to be living with at least one chronic condition before 2020, enhancing patient self-management support (SMS) may improve health-related behaviors and clinical outcomes. Routine SMS implementation in primary care settings is difficult. Little is known about the practice conditions required for successful implementation of SMS tools.

METHODS

Four primary care practice-based research networks (PBRNs) recruited 16 practices to participate in a boot camp translation process to adapt patient-centered SMS tools. Boot camp translation sessions were held over a 2-month period with 2 patients, a clinician, and a care manager from each practice. Qualitative case comparison and qualitative comparative analysis were used to examine practice conditions needed to implement SMS tools. The Consolidated Framework for Implementation Research guided data collection and analysis.

RESULTS

Four different practice conditions affected the implementation of new SMS tools: functional practice organization; system that enables innovation and change; presence of a visible, activated champion; and synergy and alignment of SMS changes with other work. Qualitative comparative analysis suggested that it was necessary to have an enabling system, a visible champion, and synergy for a practice to at least minimally implement the SMS tools. Sufficiency testing, however, failed to show robust consistency to satisfactorily explain conditions required to implement new SMS tools.

CONCLUSIONS

To implement tailored self-management support tools relatively rapidly, the minimum necessary conditions include a system that enables innovation and change, presence of a visible champion, and alignment of SMS changes with other work; yet, these alone are insufficient to ensure successful implementation.

How to Translate Self-Management Support Tools Into Clinical Practice: A Report From the INSTTEPP Trial and Meta-LARC Consortium

PURPOSE

Patient self-management is an inevitable part of the work of being a patient, and self-management support (SMS) has become increasingly important in chronic disease management. However, the majority of SMS resources available in the Agency for Healthcare Research and Quality SMS Resource Library were developed without explicit collaboration between clinicians and patients.

METHODS

Translation of SMS tools derived from the library into primary care practices occurred utilizing boot camp translation in four different practice-based research networks (PBRNs). The typical model of boot camp translation was adapted for the purpose of the Implementing Networks' Self-management Tools Through Engaging Patients and Practices (INSTTEPP) study to develop SMS tools for implementation in the participating practices. Clinicians, clinic staff members, and patients were involved throughout the translation process. Existing resources from the SMS library were reviewed and adapted by each boot camp translation group to create tools unique to the patients in each network.

RESULTS

There was no preexisting resource within the library that was deemed suitable for implementation without modification. Each network adapted tools from the SMS library to create different products. Common themes emerged from each network's translation process that highlighted the importance of patient engagement in the translation process. Boot camp translation, in conjunction with PBRNs, can be implemented to adapt SMS tools for implementation in member practices.

CONCLUSIONS

Boot camp translation with a combination of practices and patients can be implemented to facilitate a process of local adaptation that improves the local applicability of SMS tools in primary care clinics.

Practice-Based Research Networks Ceding to a Single Institutional Review Board: A Report From the INSTTEPP Trial and Meta-LARC Consortium

Historically, a single research project involving numerous practice-based research networks (PBRNs) required multiple institutional review boards (IRBs) to be involved in approval of the project. However, to avoid redundancies, federal IRB regulations now allow cooperative research projects that involve more than one institution to use reasonable methods of cooperative IRB review and to cede authority for review and oversight of the project to a single lead IRB. Through ceding, a lead IRB has the authority for review and oversight of the project delegated by all participating sites' IRBs and becomes the IRB of record for the ceded sites. In the conduct of cooperative research projects, each institution or primary care office site is still responsible for safeguarding the rights and welfare of human subjects and for complying with applicable regulations. The purpose of this report is to delineate the process, including cooperation and effort of personnel, for accomplishing IRB approval for the Implementing Networks' Self-management Tools Through Engaging Patients and Practices (INSTTEPP) clinical trial. This process involved 4 PBRNs, 16 family physician offices, 4 academic institution's IRBs, and 4 family practice office external IRBs ceding to the lead IRB. Once ceding was accomplished, subsequent IRB modifications and continuing reviews were the responsibility of the lead IRB, ultimately saving time for all participants and keeping the project on schedule.

Strategies used and lessons learned by community assistants in organising regional forums for cancer education in Iowa, USA

Cancer prevention efforts at the community level are essential in the fight against cancer. Understanding community dynamics provides insights into building meaningful relationships between researchers and community organizations. In this study, community assistants were hired to organize and host forums to encourage interdisciplinary collaboration, with the goal of strengthening and transforming relationships between a university academic health center and communities. A 19-item questionnaire was developed to determine the strategies community assistants used to schedule and host community forums. Community assistants completed the questionnaire and were interviewed. Community assistants successfully scheduled and hosted 113 forums in 49 cities throughout the state of Iowa, with 2,209 persons attending. Strategies used included cold calls, using contact lists from the Iowa Cancer Consortium membership list, and contacts from business associates. Additionally, electronic and social media were used to arrange and advertise scheduled forums. The various strategies used and lessons learned by the community assistants proved successful in organizing and hosting forums throughout the state of Iowa, which reached 40 of Iowa's 99 counties. The efforts of the community assistants, the Iowa Cancer Consortium, and the Iowa Research Network, laid the foundation for continued cancer research and education collaboration between researchers and community organizations.

The challenges posed by equine arboviruses

Equine populations worldwide are at increasing risk of infection by viruses transmitted by biting arthropods, including mosquitoes, biting midges (Culicoides), sandflies and ticks. These include the flaviviruses (Japanese encephalitis, West Nile and Murray Valley encephalitis), alphaviruses (eastern, western and Venezuelan encephalitis) and the orbiviruses (African horse sickness and equine encephalosis). This review provides an overview of the challenges faced in the surveillance, prevention and control of the major equine arboviruses, particularly in the context of these viruses emerging in new regions of the world.

Epidemiological survey of equine influenza in Andalusia, Spain

Equine influenza is a highly contagious respiratory disease considered the most important respiratory disease in equids. Although influenza A virus (IAV) has caused outbreaks in equids worldwide, surveillance in these species in Spain has not been conducted. A cross-sectional study was carried out to determine the individual and herd prevalence of antibodies against H3N8 and H7N7 IAV in equids in Andalusia (southern Spain). Antibodies againsts IAV were measured by the single radial haemolysis assay. A spatial scan statistical analysis was carried out using a Bernoulli model. Risk factors associated with IAV infection were assessed by multivariate analysis. Antibodies to H3N8 IAV were detected in 241 out of 464 unvaccinated equids (51.9%; 95% CI: 47.4-56.5). Seropositivity against the H7N7 subtype IAV was not found in any of the analysed animals. Significantly higher seropositivity was found in geriatric (OR = 6.1, P = 0.008, 95% CI = 1.6-23.1) and adult (OR = 4.8, P < 0.001, 95% CI = 2.5-9.0) equids compared to young animals. Specific antibodies against A/equine/Shropshire/2010 (H3N8) or A/equine/Newmarket/5/2003 (H3N8) only were confirmed in 11 and 45 of the animals, respectively. The spatial analysis showed a statistically significant cluster centred in the west part of Andalusia. The results confirmed widespread H3N8 subtype IAV exposure in equine species in Andalusia. Conversely, the absence of seropositivity against H7N7 IAV obtained in the present study suggests that this subtype has not circulated in southern Spain in recent years. Because of the animal health and economic consequences of IAV in equids, further surveillance and molecular studies are required to monitor and characterize the most prevalent IAV circulating in these species in Spain.

The challenge of teaching undergraduates evidence-based veterinary medicine

The Royal College of Veterinary Surgeons now lists 'How to evaluate evidence' as a day one competence for newly qualified vets. In this article, representatives from each of the veterinary schools in the UK discuss how the challenge of delivering and assessing the concepts of evidence-based veterinary medicine in a crowded undergraduate curriculum can be met.

Which Fecal Immunochemical Test Should I Choose?

OBJECTIVES

To summarize the fecal immunochemical tests (FITs) available in the United States, the 2014 pathology proficiency testing (PT) program FIT results, and the literature related to the test characteristics of FITs available in the United States to detect advanced adenomatous polyps (AAP) and/or colorectal cancer (CRC).

METHODS

Detailed review of the Food and Drug Administration's Clinical Laboratory Improvement Amendments (CLIA) database of fecal occult blood tests, the 2014 FIT PT program results, and the literature related to FIT accuracy.

RESULTS

A search of the CLIA database identified 65 FITs, with 26 FITs available for purchase in the United States. Thirteen of these FITs were evaluated on a regular basis by PT programs, with an overall sensitivity of 99.1% and specificity of 99.2% for samples spiked with hemoglobin. Automated FITs had better sensitivity and specificity than CLIA-waived FITs for detection of AAP and CRC in human studies using colonoscopy as the gold standard.

CONCLUSION

Although many FITs are available in the United States, few have been tested in proficiency testing programs. Even fewer have data in humans on sensitivity and specificity for AAP or CRC. Our review indicates that automated FITs have the best test characteristics for AAP and CRC.

Iowa Dependent Adult Abuse Prosecutions From 2006 Through 2015: Health Care Providers' Concern

Background: In most states, health care providers are required to report abuse. Some states provide investigation feedback/findings to the reporter. The reporters rarely know if the perpetrator is convicted. The purposes of this study are to determine the incidence of Iowa dependent adult abuse prosecutions from 2006 through 2015, the incidence of convictions, and the association between dependent adult abuse prosecutions with county census and government characteristics. Design and Methods: Through the Iowa Court Information Systems, dependent adult abuse prosecution data were purchased for a 10-year time period. County demographics were obtained through the US Census and government data were Iowa State Association of Counties and the US Department of Agriculture. Results: During 2006-2015, there were 368 dependent adult abuse prosecution cases accounting for 482 original charges. Exploitation greater than $100 was the dependent adult abuse charge most frequently cited. Within the 10 years, it accounted for 60% of the original charges. Of the 482 disposed charges, 251 (52%) of the charges were dismissed. A total of 122 (14%) counts resulted in probation, 73 resulted in prison, and 37 in jail. Conclusions: For the first time, information about dependent adult abuse prosecutions in Iowa is available. The latter 5 years, 2011 to 2015, of dependent adult abuse prosecutions are significantly higher than the first 5 years, 2006 to 2010. This project encourages health care providers to report dependent adult abuse to law enforcement if appropriate as well as adult protective services.

Canine parvovirus (CPV-2) variants circulating in Nigerian dogs

Canine parvovirus type 2 (CPV-2) is a highly contagious viral disease with three variants (CPV-2a, CPV-2b and CPV-2c) currently circulating in dogs worldwide. The main aim of this study was to determine the prevalent CPV-2 variant in faecal samples from 53 dogs presenting with acute gastroenteritis suspected to be and consistent with CPV-2 to Nigerian Veterinary Clinics in 2013–2014. Seventy-five per cent of these dogs tested positive for CPV-2 in a commercial antigen test and/or by PCR. Partial sequencing of the VP2 gene of six of these demonstrated them to be CPV-2a. Most of the dogs (60 per cent) were vaccinated, with 74 per cent of them puppies less than six months old.

Factors Associated With Self-Reported Elder Mistreatment in Iowa’s Frailest Elders

The purposes of this study were to determine associated characteristics of community-dwelling older persons, their access to care and social provisions, and self-reported elder abuse, and to assess how having help in completing a questionnaire affected these associations. A questionnaire was mailed to 1,017 randomly selected elders in the Iowa Medicaid Waiver Program. The overall prevalence of self-reported abuse was 20.9%. Fifty-nine percent of respondents had help completing the questionnaire. Abuse was associated with low social provisions, more emergency room visits, being alone, and not having enough money. For those having help completing the questionnaire, abuse was associated with older age, low social provisions, being alone, and not having enough money. For those having no help completing the questionnaire, abuse was associated with depression, being alone, more emergency room visits, and low social provisions. Among community-living elders needing services in their homes, the prevalence of abuse was higher than that found in general population studies.

In Vitro Flow Rates of Enteral Solutions through Nasoenteric Tubes

Enteral solutions must flow freely through nasoenteric tubes selected for gravity drip administration particularly in outpatients receiving nutritional support. This study determined in vitro flow rates of solutions with intact protein and hydrolyzed protein sources with various caloric densities. Each solution was infused through silicone rubber and polyurethane tubes of various lengths and bore sizes. Flow rates were measured five times at 25 degrees C using formula bags and drip sets hung at a uniform height and tubes uniformly positioned in a collecting vessel. Data are presented for tubes and formulas tested. Recommendations for selection of tubes for gravity drip administration are made based on flow rate data, patient comfort, administration convenience, and patient tolerance to osmolality.

Factors Associated With Parents' Perceptions of Their Infants' Oral Health Care

INTRODUCTION

Parents have an important role ensuring their infants receive oral and medical health care. Their decisions affect the well-being of their children.

METHODS

This study used data collected from a longitudinal, prospective study with the aim of developing and validating a caries risk assessment tool. The objectives of this study are to (a) compare parents' perceptions of how well they do in taking care of the infants' teeth and/or gums versus how well they do in taking care of the infants' medical health and (b) determine factors associated with parental perceptions of how well they do in taking care of the infants' teeth and/or gums.

RESULTS

A total of 1323 parent/infant pairs were enrolled in the study at Duke University, Indiana University, and the University of Iowa. Through a survey, 283 (21%) of the parents perceived they did an excellent job of both taking care of both the infant's oral and medical health, while 861 (65%) perceived the care of their infant's medical health was better than their care of the teeth and/or gums. In the multivariable model, parents who perceived they provided excellent/very good/good care for the infants' teeth and/or gums were more likely to brush the infant's teeth daily, use toothpaste daily, clean inside the infant's mouth and/or gums daily, and not let the infant have something other than water after brushing and prior to bedtime. Also, those with infants having Medicaid or State Insurance, parents not eating sugary snacks frequently, and parents getting dental checkups at least annually were likely to perceive that they provided excellent/very good/good care for their infant's teeth and/or gums.

CONCLUSIONS

Parents who provide good infant oral health care are more likely to perceive they provide good care and more likely to have better personal dental health behaviors. This agrees with previous studies concerning older children.

Recruitment strategies at the Iowa site for parent/infant pairs in a longitudinal dental caries study

BACKGROUND/AIMS

Recruitment of parent/infant pairs can be more difficult and challenging than recruitment of adult subjects alone as the parent has to consider themselves along with the infant to be study participants. In order to determine which recruitment methods most effectively resulted in accrual of subjects, recruitment efforts at the University of Iowa were evaluated, one of three clinical sites involved in a longitudinal prospective study of dental caries.

METHODS

Enrollment goals were 300 parent/infant pairs within a year. Recruitment strategies included (1) a direct mailing to potential subjects who were University of Iowa Hospitals and Clinics patients and potentially met inclusion criteria; (2) face-to-face recruitment visits at medical offices; (3) provision of recruitment materials to staff at off-campus agencies and medical offices serving low-income individuals; (4) a campus-wide mass e-mail; (5) recruitment materials to daycare centers and neighborhood centers; and (6) recruitment at a children's museum.

RESULTS

From these recruitment efforts, 515 potential participants expressed interest and were screened for this study and 348 (68%) were enrolled during an 11-month time period. The face-to-face strategy had the highest recruitment rate of 25%, followed by direct individual mailings at 9% and follow-up telephone calls at 7%. For the face-to-face strategy, the contact at the children's museum was most successful compared to the other office settings. The lowest rate of recruitment of 0.09% was attained with the mass e-mail. However, in terms of actual numbers recruited, the mass e-mail remained an important modality since it yielded 21 recruits and was much less time-intensive.

CONCLUSION

An intensive, multi-pronged recruitment strategy proved successful in meeting enrollment goals and resulted in finishing the enrollment prior to the projected study deadline. Effective recruitment approaches are imperative for a study's success and each recruitment strategy needs to be budgeted and planned for in a study. Investigators may need to adapt their approach to attain the needed number of subjects. Planning needs to include the numbers needed to be approached to attain your recruitment goal, how you will recruit, who will be responsible, and the costs and time commitment for various strategies.

Team Science Approach to Developing Consensus on Research Good Practices for Practice-Based Research Networks: A Case Study

Using peer learning strategies, seven experienced PBRNs working in collaborative teams articulated procedures for PBRN Research Good Practices (PRGPs). The PRGPs is a PBRN-specific resource to facilitate PBRN management and staff training, to promote adherence to study protocols, and to increase validity and generalizability of study findings. This paper describes the team science processes which culminated in the PRGPs. Skilled facilitators used team science strategies and methods from the Technology of Participation (ToP®), and the Consensus Workshop Method to support teams to codify diverse research expertise in practice-based research. The participatory nature of "sense-making" moved through identifiable stages. Lessons learned include (1) team input into the scope of the final outcome proved vital to project relevance; (2) PBRNs with diverse domains of research expertise contributed broad knowledge on each topic; and (3) ToP® structured facilitation techniques were critical for establishing trust and clarifying the "sense-making" process.

Effect of Ambient Temperature Variations on Positivity of Manual Fecal Immunochemical Tests

INTRODUCTION

In the United States, many fecal occult blood tests are mailed by patients to a laboratory for analysis. Hemoglobin is not stable in feces and can be affected by the heat. Effects of season and ambient temperature on fecal immunochemical tests (FITs) have demonstrated a decrease in positivity rates during the hottest season.

OBJECTIVE

To investigate the potential effect of the average of 4-day ambient maximum temperature variations on the positivity of a single sample, one-time Clinical Laboratory Improvement Amendments (CLIA)-waived FIT.

SETTING

Midwestern tertiary care hospital.

METHODS

Individuals scheduled for a colonoscopy were invited to complete a qualitative FIT prior to their colonoscopy in 2010 and 2011. FITs were read as positive or negative.

RESULTS

Valid FITs were received from 1026 individuals over 25 months. The positivity rate was 10.9%. The mean 4-day average of daily maximum ambient temperatures was calculated including the day of receipt for each sample. Fahrenheit temperatures ranged from 16.0 to 96.8. Based on the odds ratio of 1.04 with a confidence interval of 0.94 to 1.14 for a 10°F increase in temperature, there was no statistically significant evidence of an effect of the preceding maximum average 4-day ambient temperature on FIT positivity.

CONCLUSION

No evidence was found that ambient temperature had an effect on positivity rate over a 25-month period using 4 different qualitative FIT products. Further analysis on effect of ambient temperatures is warranted for the automated FITs and CLIA-waived FITs, including liquid-vial and dry-slide FITs. Primary care providers need to be aware of potential adverse effects of FITs.

Comparison of patient preferences for fecal immunochemical test or colonoscopy using the analytic hierarchy process

Background

In average-risk individuals aged 50 to 75 years, there is no difference in life-years gained when comparing colonoscopy every 10 years vs. annual fecal immunochemical testing (FIT) for colorectal cancer screening. Little is known about the preferences of patients when they have experienced both tests.

Methods

The study was conducted with 954 patients from the University of Iowa Hospital and Clinics during 2010 to 2011. Patients scheduled for a colonoscopy were asked to complete a FIT before the colonoscopy preparation. Following both tests, patients completed a questionnaire which was based on an analytic hierarchy process (AHP) decision-making model.

Results

In the AHP analysis, the test accuracy was given the highest priority (0.457), followed by complications (0.321), and test preparation (0.223). Patients preferred colonoscopy (0.599) compared with FIT (0.401) when considering accuracy; preferred FIT (0.589) compared with colonoscopy (0.411) when considering avoiding complications; and preferred FIT (0.650) compared with colonoscopy (0.350) when considering test preparation. The overall aggregated priorities were 0.517 for FIT, and 0.483 for colonoscopy, indicating patients slightly preferred FIT over colonoscopy. Patients’ preferences were significantly different before and after provision of detailed information on test features (p < 0.0001).

Conclusions

AHP analysis showed that patients slightly preferred FIT over colonoscopy. The information provided to patients strongly affected patient preference. Patients’ test preferences should be considered when ordering a colorectal cancer screening test.

System Strategies for Colorectal Cancer Screening at Federally Qualified Health Centers

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.

iPad use in Iowa Research Network family physician offices

BACKGROUND

Through a cancer research infrastructure building grant, iPads were given to health care providers in family physician offices. The purpose of this study was to determine the use and application of iPads in the Iowa Research Network.

METHODS

A Qualtrics survey was sent to 81 iPad recipients after institutional review board approval.

RESULTS

Fifty-nine percent responded and 85% reported they have used the iPad. The main reason for use of the iPad was browsing the World Wide Web for health care information. Open-ended comments supported use of the iPad for photographic documentation of wound and other skin lesions for insertion into the medical record and it helped improve clinic flow by making it easier to put orders in the system through the iPad.

CONCLUSIONS

Tablet uses are variable in physician offices with provider's gathering health care information from the Internet and securing education material for patients as the frequent usages.

Test characteristics of faecal immunochemical tests (FIT) compared with optical colonoscopy

BACKGROUND

Faecal occult blood tests are often the initial test in population-based screening. We aimed to: 1) compare the results of single sample faecal immunochemical tests (FITs) with colonoscopy, and 2) calculate the sensitivity for proximal vs. distal adenomatous polyps or cancer.

METHODS

Individuals scheduled for a colonoscopy were invited to complete a FIT prior to their colonoscopy preparation. FIT results were classified as positive, negative, or invalid. Colonoscopy reports were reviewed and abstracted. Because of product issues, four different FIT manufacturers were used. The test characteristics for each FIT manufacturer were calculated for advanced adenomatous polyps or cancer according to broad reason for colonoscopy (screening or surveillance/diagnostic).

RESULTS

Of those invited, 1,026 individuals (43.9%) completed their colonoscopy and had a valid FIT result. The overall sensitivity of the FITs (95% confidence intervals) was 0.18 (0.10 to 0.28) and specificity was 0.90 (0.87 to 0.91) for advanced adenomas or cancer. The sensitivity for distal lesions was 0.23 (0.11 to 0.38) and for proximal lesions was 0.09 (0.02 to 0.25). The odds ratio of an individual with a distal advanced adenoma or cancer testing positive was 2.68 (1.20 to 5.99). The two individuals with colorectal cancer tested negative, as did one individual with high-grade dysplasia.

CONCLUSIONS

The sensitivity of a single-sample FIT for advanced adenomas or cancer was low. Individuals with distal adenomas had a higher odds of testing positive than those with proximal lesions or no lesions.

Colon polyp model use for educating about colorectal cancer screening in the Iowa Research Network

Providing a model of a colon segment with an adenomatous polyp and cancer can help to educate patients about the adenoma to carcinoma sequence and how this sequence can be interrupted with appropriate testing. The purpose of this study was to assess the use of a three-dimensional colon model with polyps and cancer provided to family physicians or nurses in some Iowa Research Network family physician offices. Colon models were provided to 117 family medicine healthcare providers interested in colorectal cancer screening. Using a mailed survey and follow-up telephone calls to non-responders, 81 (69%) questionnaires were returned. Thirty-six (44%) of the respondents reported they had used the model, 33 (41%) reported they used the model for a mean 16% of their patients in a month's time, 31 (38%) reported using the model to teach patients about the colon and polyps prior to a colonoscopy. Other model use described by respondents included educating staff to promote patient willingness for colonoscopies, demonstrating the need for colon cancer screening, and teaching patients about annual fecal occult blood tests. Respondents agreed that anatomical models are helpful for patient education, the design of the colon model was good, and that it facilitated demonstration of colon polyps. Possible recommendations for an office-wide adoption of an anatomical model would be an in-service for all employees and a standard location for finding the model.

Use of fecal immunochemical tests in the Iowa Research Network

Although the fecal immunochemical test (FIT) has recently emerged as an effective and affordable colorectal cancer screening option, many family physician offices continue to use guaiac-based tests. The purpose of this study was to assess the use of FITs in the Iowa Research Network and to assess physicians' knowledge about FITs. A cover letter and questionnaire were faxed twice to the 291 physician members followed up by a mailing. One hundred and seven (37%) questionnaires were returned. Participants' mean age was 55 years with 78 male responders. Fifty-two (49%) of the physician's offices were in a nonmetro area. Fifty-one (49%) reported using guaiac-based tests and 39 (39%) reported using FITs. Many physicians were unsure of the answers for the FIT knowledge questions. FIT use is not widespread in Iowa Research Network physician offices, and not all physicians are aware of the type of fecal occult blood test being conducted in their office.

The "Iowa get screened" colon cancer screening program

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.

Evaluation of fecal immunochemical tests for colorectal cancer screening

BACKGROUND

Colorectal cancer (CRC) screening reduces the mortality due to CRC. It is important for health care providers to be aware of the variation in the products available for CRC screening.

PURPOSE

The purpose of this study was to summarize the accuracy of results of individual fecal immunochemical test (FIT) products across pathology proficiency testing programs.

METHODS

Secondary data analysis of proficiency testing programs' FIT results.

RESULTS

Four of 7 proficiency testing program's FIT evaluations were obtained for a 2-year period. Fourteen unique FIT brands were evaluated by at least 1 of the 4 proficiency testing programs. Five of the products performed similarly with sensitivities ranging from 98.1% to 98.8% and specificities from 98.1% to 99.6%. Ninety-three percent of the FIT tests completed were manual Clinical Laboratory Improvement Amendments-waived FITs.

CONCLUSIONS

About two thirds of the commonly used FIT products performed acceptably on spiked samples of human hemoglobin. However, some had low sensitivity and specificity and probably should not be used for population-based or other screening. Further investigation to determine appropriate, reliable products for fecal occult blood testing is warranted.

Patients whose physicians recommend colonoscopy and those who follow through

BACKGROUND

More than half of eligible individuals are not up-to-date with colon cancer screening.

PURPOSE

To assess the characteristics of those who received a colonoscopy screening recommendation and those who followed the physician recommendation.

METHODS

Patient self-administered questionnaire and medical record review in 16 private family physician practices.

RESULTS

From 8372 patients invited to participate, 685 were enrolled and had a medical record review; 219 (32%) had a colonoscopy recommendation and 86 (39%) received a colonoscopy. Independent factors associated with having a recommendation for colonoscopy were significantly younger in age (odds ratios [OR] = 1.6), higher incomes (annual income ≥$40 000 vs <$40 000; OR = 1.8), physician or nurse discussion about colon cancer tests (OR = 1.6), physical visit in the preceding 26 months (OR = 1.7), distant relative with colon cancer (OR = 2.4), and a medical diagnosis of hyperlipidemia (OR = 2.1). Independent factors associated with following through on colonoscopy after a recommendation were age ≥65 years (OR = 0.3), male patient (OR = 0.4), and feeling that colon cancer screening is very important (OR = 3.2).

CONCLUSIONS

Socioeconomic factors are associated with receipt of a colonoscopy recommendation. Fewer than one third of patients had documentation of a physician colonoscopy recommendation and of those, less than half followed through.
