Peer Reviewed: Collaboration to Increase Colorectal Cancer Screening Among Low-Income Uninsured Patients

Background

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. CRC screening allows for prevention through the removal of precancerous lesions and early detection of cancer.

Community Context

Ride for Life Alaska (RFL), a nonprofit organization that raises funds to fight cancer, and the Anchorage Neighborhood Health Center (ANHC), which is Alaska''s largest community health center, joined efforts to provide CRC screening and outreach to an ethnically diverse group of low-income underinsured or uninsured patients residing in and around Anchorage, Alaska.

Methods

RFL and ANHC worked with gastroenterologists, medical practices, and pathology services to contribute pro bono and reduced-fee services for CRC screening. Information to patients was distributed through signs in the clinic, flyers, and the ANHC website.

Outcomes

CRC screening was increased in this population. During 2007-2009, there were 2,561 immunochemical fecal occult blood tests given to patients, and 1,558 were completed (61%); 24% were positive. Sixteen gastroenterologists, 4 medical practices, and 2 laboratories provided 111 follow-up colonoscopies and pathology services to patients identified through the CRC screening program who did not have other funding resources available for follow-up care.

Interpretation

This program provides a model for leveraging scarce screening resources by drawing on multiple partners to increase CRC screening. Recommendations for those seeking to initiate similar programs are to have memoranda of agreement in place and a clear scope of work for all participating people and organizations to avoid delays in program implementation; hire a screening care coordinator to manage patient care and collaborate with medical practices; and identify program champions who have the energy and persistence to craft such partnerships.     

TRIPPD: a practice-based network effectiveness study of postpartum depression screening and management

PURPOSE

Postpartum depression is common but inadequately recognized and undertreated. Continuing depressive symptoms are associated with adverse outcomes for the woman, her infant, and family. We wanted to determine the effect of a practice-based training program for screening, diagnosis, and management of depression in postpartum mothers.

METHODS

In this practice-based effectiveness study, 28 practices were randomized to usual care (n = 14) or intervention (n = 14), and 2,343 women were enrolled between 5 and 12 weeks’ postpartum. The intervention sites received education and tools for postpartum depression screening, diagnosis, initiation of therapy, and follow-up within their practices. Usual-care practices received a 30-minute presentation about postpartum depression. Screening information for the usual care was obtained from baseline surveys sent directly to the central site but was not available for patient care. Outcomes were based on patient-reported outcomes (level of depressive symptoms) from surveys at 6 and 12 months, plus medical record review (diagnosis and therapy initiation).

RESULTS

Among the 2,343 women enrolled, 1,897 (80.1%) provided outcome information, and were included in the analysis. Overall, 654 (34.5% of 1,897) women had elevated screening scores indicative of depression, with comparable rates in the intervention and usual-care groups. Among the 654 women with elevated postpartum depression screening scores, those in the intervention practices were more likely to receive a diagnosis (P = .0006) and therapy for postpartum depression (P = .002). They also had lower depressive symptom levels at 6 (P = .07) and 12 months’ (P=.001) postpartum.

CONCLUSIONS

Primary care–based screening, diagnosis, and management improved mother’s depression outcomes at 12 months. This practical approach could be implemented widely with modest resources.     

Vital Signs: Colorectal Cancer Screening Test Use — United States, 2012

Background

Strong evidence exists that screening with fecal occult blood testing (FOBT), sigmoidoscopy, or colonoscopy reduces the number of deaths from colorectal cancer (CRC). The percentage of the population up-to-date with recommended CRC screening increased from 54% in 2002 to 65% in 2010, primarily through increased use of colonoscopy.

Methods

Data from the 2012 Behavioral Risk Factor Surveillance System survey were analyzed to estimate percentages of adults aged 50–75 years who reported CRC screening participation consistent with United States Preventive Services Task Force recommendations.

Results

In 2012, 65.1% of U.S. adults were up-to-date with CRC screening, and 27.7% had never been screened. The proportion of respondents who had never been screened was greater among those without insurance (55.0%) and without a regular care provider (61.0%) than among those with health insurance (24.0%) and a regular care provider (23.5%). Colonoscopy was the most commonly used screening test (61.7%), followed by FOBT (10.4%). Colonoscopy was used by more than 53% of the population in every state. The percentages of blacks and whites up-to-date with CRC screening were equivalent. Compared with whites, a higher percentage of blacks across all income and education levels used FOBT.

Conclusions

Many age-eligible adults did not use any type of CRC screening test as recommended. Organized, population-based approaches might increase CRC screening among those who have never been screened. Promoting both FOBT and colonoscopy as viable screening test options might increase CRC screening rates and reduce health disparities.     

Peer Reviewed: Barriers to Colorectal Cancer Screening: Physician and General Population Perspectives,New Mexico, 2006

Introduction

Colorectal cancer (CRC) screening rates are low in New Mexico. We used statewide surveys of primary care physicians and the general population to characterize CRC screening practices and compare perceptions about screening barriers.

Methods

In 2006, we surveyed 714 primary care physicians in New Mexico about their CRC screening practices, beliefs, and perceptions of patient, provider, and system barriers. A 2004 state-specific CRC screening module for the Behavioral Risk Factor Surveillance System (BRFSS) survey asked 3,355 participants aged 50 years or older why they had not ever or had not recently completed a fecal occult blood test (FOBT) or lower endoscopy.

Results

The 216 physicians (30% response rate) reported offering screening to a median 80% of their average-risk patients in the past year and estimated that a median 50% were current with screening. They attributed low screening proportions mainly to patient factors (embarrassment, fear of pain, lack of insurance). However, just 51% of physician respondents used health maintenance flow sheets, and only 13% used electronic medical records to identify patients due for CRC screening. The BRFSS respondents most often reported that lack of physician discussion was responsible for not being current with screening (45% FOBT, 34% endoscopy); being asymptomatic was also often cited as an explanation for lack of screening (22% FOBT, 36% endoscopy).

Conclusion

Physicians and adults in the general population had markedly different perspectives on barriers to CRC screening. Increasing screening may require system supports to help physicians readily identify patients due for CRC testing and interventions to educate patients about the rationale for screening.     

Primary Care Physicians and Disparities in Colorectal Cancer Screening in the Elderly

Objective

To examine whether having a primary care physician (PCP) is associated with reduced ethnic disparities for colorectal cancer (CRC) screening and whether clustering of minorities within PCPs contributes to the disparities.

Data Sources/Study Setting

Retrospective cohort study of Medicare beneficiaries age 66–75 in 2009 in Texas.

Study Design

The percentage of beneficiaries up to date in CRC screening in 2009 was stratified by race/ethnicity. Multilevel models were used to study the effect of having a PCP and PCP characteristics on the racial and ethnic disparities on CRC screening.

Data Collection/Extraction Methods

Medicare data from 2000 to 2009 were used to assess prior CRC screening.

Principal Findings

Odds of undergoing CRC screening were more than twice as high in patients with a PCP (OR = 2.05, 95 percent CI 2.03–2.07). After accounting for clustering and PCP characteristics, the black–white disparity in CRC screening rates almost disappears and the Hispanic–white disparity decreases substantially.

Conclusions

Ethnic disparities in CRC screening in the elderly are mostly explained by decreased access to PCPs and by clustering of minorities within PCPs less likely to screen any of their patients.     

Overcoming Challenges in the Changing Environment of Practice-Based Research

PURPOSE

Conducting studies in national practice-based research networks presents logistic and methodologic challenges. Pediatric Research in Office Settings (PROS) has learned valuable lessons in implementing new strategies and adapting to challenges. We describe practical challenges and results of novel applied strategies in implementing and testing the Clinical Effort Against Secondhand Smoke Exposure (CEASE) intervention as part of a national-level cluster-randomized controlled trial.

METHODS

In the trial, 20 PROS practices were randomized to either a CEASE intervention arm or a control arm. Parents of children seen in the office who indicated smoking in the past 7 days were asked to complete a postvisit enrollment interview and telephone interviews 3 and 12 months later. Identified challenges included (1) recruiting 20 practices serving a high percentage of parent smokers; (2) screening all parents bringing children for visits and enrolling eligible parents who smoked; and (3) achieving an acceptable 12-month telephone response rate.

RESULTS

A total of 47 interested practices completed the Practice Population Survey, of which 20 practices in 16 states completed parent enrollment. Thirty-two research assistants screened 18,607 parents and enrolled 1,980 of them. The initial telephone interview response rate was 56% at 12 months, with incorrect and disconnected numbers accounting for nearly 60% of nonresponses. The response rate rose to 67% after practices supplied 532 new contact numbers and 754 text messages were sent, with 389 parents completing interviews.

CONCLUSION

The strategies we used to overcome methodologic barriers in conducting a national intervention trial allowed data collection to be completed in the office setting and increased the telephone interview response rate.     

Cost-Effectiveness of a Proactive Primary Care Program for Frail Older People: A Cluster-Randomized Controlled Trial

Background

A proactive integrated approach has shown to preserve daily functioning among older people in the community. The aim is to determine the cost-effectiveness of a proactive integrated primary care program.

A Randomized,Controlled Pragmatic Trial of Telephonic Medication Therapy Management to Reduce Hospitalization in Home Health Patients

Objective

To evaluate the effectiveness of a telephonic medication therapy management (MTM) service on reducing hospitalizations among home health patients.

Setting

Forty randomly selected, geographically diverse home health care centers in the United States.

Design

Two-stage, randomized, controlled trial with 60-day follow-up. All Medicare- insured home health care patients were eligible to participate. Twenty-eight consecutive patients within each care center were recruited and randomized to usual care or MTM intervention. The MTM intervention consisted of the following: (1) initial phone call by a pharmacy technician to verify active medications; (2) pharmacist-provided medication regimen review by telephone; and (3) follow-up pharmacist phone calls at day seven and as needed for 30 days. The primary outcome was 60-day all-cause hospitalization.

Data Collection

Data were collected from in-home nursing assessments using the OASIS-C. Multivariate logistic regression modeled the effect of the MTM intervention on the probability of hospitalization while adjusting for patients’ baseline risk of hospitalization, number of medications taken daily, and other OASIS-C data elements.

Principal Findings

A total of 895 patients (intervention n = 415, control n = 480) were block-randomized to the intervention or usual care. There was no significant difference in the 60-day probability of hospitalization between the MTM intervention and control groups (Adjusted OR: 1.26, 95 percent CI: 0.89–1.77, p = .19). For patients within the lowest baseline risk quartile (n = 232), the intervention group was three times more likely to remain out of the hospital at 60 days (Adjusted OR: 3.79, 95 percent CI: 1.35–10.57, p = .01) compared to the usual care group.

Conclusions

This MTM intervention may not be effective for all home health patients; however, for those patients with the lowest-risk profile, the MTM intervention prevented patients from being hospitalized at 60 days.     

Peer Reviewed: Differences in Knowledge of Breast Cancer Screening Among African American,Arab American,and Latina Women

Introduction

We examined differences in knowledge and socioeconomic factors associated with 3 types of breast cancer screening (breast self-examination, clinical breast examination, and mammogram) among African American, Arab, and Latina women.

Methods

Community health workers used a community-based intervention to recruit 341 women (112 Arab, 113 Latina, and 116 African American) in southeastern Michigan to participate in a breast cancer prevention intervention from August through October 2006. Before and after the intervention, women responded to a previously validated 5-item multiple-choice test on breast cancer screening (possible score range: 0 to 5) in their language of preference (English, Spanish, or Arabic). We used generalized estimating equations to analyze data and to account for family-level and individual correlations.

Results

Although African American women knew more about breast cancer screening at the baseline (pretest median scores were 4 for African American, 3 for Arab and 3 for Latina women), all groups significantly increased their knowledge after participating in the breast cancer prevention intervention (posttest median scores were 5 for African American and 4 for Arab and Latina women). Generalized estimating equations models show that Arab and Latina women made the most significant gains in posttest scores (P < .001).

Conclusion

Racial/ethnic differences in knowledge of breast cancer screening highlight the need for tailored information on breast cancer screening for African American, Arab, and Latina women to promote adherence to breast cancer screening guidelines.     

Peer Reviewed: Assessing Colorectal Cancer Screening Knowledge at Tribal Fairs

Introduction

Increasing public awareness and knowledge about the need for colorectal cancer (CRC) screening among American Indians is key to reducing health disparities. The objective of this study was to assess Navajo adults'' knowledge of CRC risk factors and prevention, CRC screening, and self-reported experience with CRC screening.

Methods

We collected data generated by a self-administered survey given to Navajo adults, most of whom lived on the reservation. Data were collected at 2 annual tribal fairs in 2006. Fair attendees who visited an exhibit booth completed a CRC knowledge survey. The study design was nonrandomized.

Results

Of the 285 Navajo adults who participated, most were bilingual (74%) and female (80%). Of the respondents aged 50 years or older, 77% had heard of CRC screening and 28% reported being screened for colon or colorectal cancer. Knowledge was high (mean, 5.78 [standard deviation (SD), 1.28]) (8.0 was the highest possible knowledge score). Respondents with little or no formal schooling had lower scores (mean, 5.4), indicating less knowledge of CRC and associated screening tests than did those with more education (mean, 6.0).

Conclusion

Among a sample of Navajo adults aged 50 years or older, participants with more education were more likely to be knowledgeable about CRC and to have received screening. This survey, led by a Navajo investigator with Navajo surveyors, revealed a high awareness of CRC and screening, but overall CRC screening was low. CRC education for Navajo adults who have little or no formal schooling should be improved.     

Midwifery Care at a Freestanding Birth Center: A Safe and Effective Alternative to Conventional Maternity Care

Objective

To estimate the effect of a midwifery model of care delivered in a freestanding birth center on maternal and infant outcomes when compared with conventional care.

Data Sources/Study Setting

Birth certificate data for women who gave birth in Washington D.C. and D.C. residents who gave birth in other jurisdictions.

Study Design

Using propensity score modeling and instrumental variable analysis, we compare maternal and infant outcomes among women who receive prenatal care from birth center midwives and women who receive usual care. We match on observable characteristics available on the birth certificate, and we use distance to the birth center as an instrument.

Data Collection/Extraction Methods

Birth certificate data from 2005 to 2008.

Principal Findings

Women who receive birth center care are less likely to have a C-section, more likely to carry to term, and are more likely to deliver on a weekend, suggesting less intervention overall. While less consistent, findings also suggest improved infant outcomes.

Conclusions

For women without medical complications who are able to be served in either setting, our findings suggest that midwife-directed prenatal and labor care results in equal or improved maternal and infant outcomes.     

Adoption,Reach, Implementation,and Maintenance of a Behavioral and Mental Health Assessment in Primary Care

PURPOSE

Guidelines recommend screening patients for unhealthy behaviors and mental health concerns. Health risk assessments can systematically identify patient needs and trigger care. This study seeks to evaluate whether primary care practices can routinely implement such assessments into routine care.

METHODS

As part of a cluster-randomized pragmatic trial, 9 diverse primary care practices implemented My Own Health Report (MOHR)—an electronic or paper-based health behavior and mental health assessment and feedback system paired with counseling and goal setting. We observed how practices integrated MOHR into their workflows, what additional practice staff time it required, and what percentage of patients completed a MOHR assessment (Reach).

RESULTS

Most practices approached (60%) agreed to adopt MOHR. How they implemented MOHR depended on practice resources, informatics capacity, and patient characteristics. Three practices mailed patients invitations to complete MOHR on the Web, 1 called patients and completed MOHR over the telephone, 1 had patients complete MOHR on paper in the office, and 4 had staff help patients complete MOHR on the Web in the office. Overall, 3,591 patients were approached and 1,782 completed MOHR (Reach = 49.6%). Reach varied by implementation strategy with higher reach when MOHR was completed by staff than by patients (71.2% vs 30.2%, P <.001). No practices were able to sustain the complete MOHR assessment without adaptations after study completion. Fielding MOHR increased staff and clinician time an average of 28 minutes per visit.

CONCLUSIONS

Primary care practices can implement health behavior and mental health assessments, but counseling patients effectively requires effort. Practices will need more support to implement and sustain assessments.     

Integrated management of type 2 diabetes mellitus and depression treatment to improve medication adherence: a randomized controlled trial

PURPOSE

Depression commonly accompanies diabetes, resulting in reduced adherence to medications and increased risk for morbidity and mortality. The objective of this study was to examine whether a simple, brief integrated approach to depression and type 2 diabetes mellitus (type 2 diabetes) treatment improved adherence to oral hypoglycemic agents and antidepressant medications, glycemic control, and depression among primary care patients.

METHODS

We undertook a randomized controlled trial conducted from April 2010 through April 2011 of 180 patients prescribed pharmacotherapy for type 2 diabetes and depression in primary care. Patients were randomly assigned to an integrated care intervention or usual care. Integrated care managers collaborated with physicians to offer education and guideline-based treatment recommendations and to monitor adherence and clinical status. Adherence was assessed using the Medication Event Monitoring System (MEMS). We used glycated hemoglobin (HbA_1c) assays to measure glycemic control and the 9-item Patient Health Questionnaire (PHQ-9) to assess depression.

RESULTS

Intervention and usual care groups did not differ statistically on baseline measures. Patients who received the intervention were more likely to achieve HbA_1c levels of less than 7% (intervention 60.9% vs usual care 35.7%; P <.001) and remission of depression (PHQ-9 score of less than 5: intervention 58.7% vs usual care 30.7%; P <.001) in comparison with patients in the usual care group at 12 weeks.

CONCLUSIONS

A randomized controlled trial of a simple, brief intervention integrating treatment of type 2 diabetes and depression was successful in improving outcomes in primary care. An integrated approach to depression and type 2 diabetes treatment may facilitate its deployment in real-world practices with competing demands for limited resources.     

Peer Reviewed: Cost-Effectiveness Analysis of Efforts to Reduce Risk of Type 2 Diabetes and Cardiovascular Disease in Southwestern Pennsylvania, 2005-2007

Introduction

We assessed the cost-effectiveness of a community-based, modified Diabetes Prevention Program (DPP) designed to reduce risk factors for type 2 diabetes and cardiovascular disease.

Methods

We developed a Markov decision model to compare costs and effectiveness of a modified DPP intervention with usual care during a 3-year period. Input parameters included costs and outcomes from 2 projects that implemented a community-based modified DPP for participants with metabolic syndrome, and from other sources. The model discounted future costs and benefits by 3% annually.

Results

At 12 months, usual care reduced relative risk of metabolic syndrome by 12.1%. A modified DPP intervention reduced relative risk by 16.2% and yielded life expectancy gains of 0.01 quality-adjusted life-years (3.67 days) at an incremental cost of $34.50 ($3,420 per quality-adjusted life-year gained). In 1-way sensitivity analyses, results were sensitive to probabilities that risk factors would be reduced with or without a modified DPP and that patients would enroll in an intervention, undergo testing, and acquire diabetes with or without an intervention if they were risk-factor–positive. Results were also sensitive to utilities for risk-factor–positive patients. In probabilistic sensitivity analysis, the intervention cost less than $20,000 per quality-adjusted life-year gained in approximately 78% of model iterations.

Conclusion

We consider the modified DPP delivered in community and primary care settings a sound investment.     

Postpartum Follow-up Rates Before and After the Postpartum Follow-up Initiative at Queen Emma Clinic

Objective

To study postpartum follow-up rates, as well as counseling opportunities, among Queen Emma Clinic patients before and after the implementation of the Queen Emma Clinic Postpartum Follow-up Initiative.

Methods

This was a retrospective chart review of 221 women who received prenatal care at the Queen Emma Clinic and gave birth between April 2006 and April 2008. In April 2007 the postpartum initiative was started. The primary outcome was the number of postpartum follow-up visits. Secondary outcomes included breastfeeding, contraceptive use, depression screening and referral, follow-up screening for patients with gestational diabetes and subsequent pregnancy.

Results

Postpartum follow-up rates were signifificantly higher after the Postpartum Follow-up Initiative (86.1% compared with 71.7%, P=.012). When comparing timing of follow-up, the first postpartum visit occurred approximately one week sooner in the post intervention group (2.96 weeks compared with 3.73 weeks, P= 0.38) with no difference in timing of the second postpartum visit (6.62 weeks compared with 6.42 weeks, P=.72). In the post intervention group there were more patients breastfeeding at the first postpartum visit (28.7% compared with 16%, P=.015), as well as the second postpartum visit (28.7% compared with 12.3%, P= 0.01). There were also more women using contraception in the post intervention group (84.3% compared with 71.7%, P=.009). There was no difference in depression screening or referral, follow-up screening for gestational diabetes, or timing of subsequent pregnancies.

Conclusion

The Postpartum Follow-Up Initiative improved postpartum follow-up rates, as well as breastfeeding, and contraceptive use.     

Economic evaluation of a task-shifting intervention for common mental disorders in India

Objective

To carry out an economic evaluation of a task-shifting intervention for the treatment of depressive and anxiety disorders in primary-care settings in Goa, India.

Methods

Cost–utility and cost–effectiveness analyses based on generalized linear models were performed within a trial set in 24 public and private primary-care facilities. Subjects were randomly assigned to an intervention or a control arm. Eligible subjects in the intervention arm were given psycho-education, case management, interpersonal psychotherapy and/or antidepressants by lay health workers. Subjects in the control arm were treated by physicians. The use of health-care resources, the disability of each subject and degree of psychiatric morbidity, as measured by the Revised Clinical Interview Schedule, were determined at 2, 6 and 12 months.

Findings

Complete data, from all three follow-ups, were collected from 1243 (75.4%) and 938 (81.7%) of the subjects enrolled in the study facilities from the public and private sectors, respectively. Within the public facilities, subjects in the intervention arm showed greater improvement in all the health outcomes investigated than those in the control arm. Time costs were also significantly lower in the intervention arm than in the control arm, whereas health system costs in the two arms were similar. Within the private facilities, however, the effectiveness and costs recorded in the two arms were similar.

Conclusion

Within public primary-care facilities in Goa, the use of lay health workers in the care of subjects with common mental disorders was not only cost–effective but also cost-saving.     

Comparison of Cardiovascular Risk Screening Methods and Mortality Data among Hungarian Primary Care Population: Preliminary Results of the First Government-Financed Managed Care Program

Introduction

Besides participation in the primary prevention, screening as secondary prevention is an important requirement for primary care services. The effect of this work is influenced by the characteristics of individual primary care practices and doctors’ screening habits, as well as by the regulation of screening processes and available financial resources. Between 1999 and 2009, a managed care program was introduced and carried out in Hungary, financed by the government. This financial support and motivation gave the opportunity to increase the number of screenings.

Method

4,462 patients of 40 primary care practices were screened on the basis of SCORE risk assessment. The results of the screening were compared on the basis of two groups of patients, namely: those who had been pre-screened (pre-screening method) for known risk factors in their medical history (smoking, BMI, age, family cardiovascular history), and those randomly screened. The authors also compared the mortality data of participating primary care practices with the regional and national data.

Results

The average score was significantly higher in the pre-screened group of patients, regardless of whether the risk factors were considered one by one or in combination. Mortality was significantly lower in the participating primary practices than had been expected on the basis of the national mortality data.

Conclusion

This government-financed program was a big step forward to establish a proper screening method within Hungarian primary care. Performing cardiovascular screening of a selected target group is presumably more appropriate than screening within a randomly selected population. Both methods resulted in a visible improvement in regional mortality data, though it is very likely that with pre-screening a more cost-effective selection for screening may be obtained.     

Statistical analyses in Swedish randomised trials on mammography screening and in other randomised trials on cancer screening: a systematic review

Objectives

We compared calculations of relative risks of cancer death in Swedish mammography trials and in other cancer screening trials.

Participants

Men and women from 30 to 74 years of age.

Setting

Randomised trials on cancer screening.

Design

For each trial, we identified the intervention period, when screening was offered to screening groups and not to control groups, and the post-intervention period, when screening (or absence of screening) was the same in screening and control groups. We then examined which cancer deaths had been used for the computation of relative risk of cancer death.

Main outcome measures

Relative risk of cancer death.

Results

In 17 non-breast screening trials, deaths due to cancers diagnosed during the intervention and post-intervention periods were used for relative risk calculations. In the five Swedish trials, relative risk calculations used deaths due to breast cancers found during intervention periods, but deaths due to breast cancer found at first screening of control groups were added to these groups. After reallocation of the added breast cancer deaths to post-intervention periods of control groups, relative risks of 0.86 (0.76; 0.97) were obtained for cancers found during intervention periods and 0.83 (0.71; 0.97) for cancers found during post-intervention periods, indicating constant reduction in the risk of breast cancer death during follow-up, irrespective of screening.

Conclusions

The use of unconventional statistical methods in Swedish trials has led to overestimation of risk reduction in breast cancer death attributable to mammography screening. The constant risk reduction observed in screening groups was probably due to the trial design that optimised awareness and medical management of women allocated to screening groups.
