Mailed outreach and facilitated test ordering to promote cholesterol screening in community health centers: A randomized trial

RATIONALE, AIMS, AND OBJECTIVES

Lipid screening is central to cardiovascular risk assessment. We sought to determine whether a simple mailed outreach message and facilitated test ordering increase cholesterol screening among federally qualified community health center patients with no recent cholesterol screening test performed.

METHODS

Using a patient-randomized controlled trial, we examined the effects of delivering a simple mailed outreach intervention promoting cholesterol testing and facilitated test ordering (without requiring an office visit). Participants were adult patients 50 to 75 years old, with no diagnosed cardiovascular disease or diabetes, and no cholesterol test within 5 years who had received care from community health centers in Illinois and Arizona. The intervention took place in 2014 and was powered to detect a 10% increase in screening due to the intervention.

RESULTS

Participants' (n = 480) mean age was 57.5 years, 51.0% were male, and 43.8% were smokers. There was no significant difference between groups in the primary study outcome-completion of total cholesterol and high-density lipoprotein cholesterol tests or complete lipid panel within 3 months; 32 participants (13.3%) in intervention group versus 26 (10.8%) in control group met the primary outcome, with absolute difference of 2.5 percentage points (95% confidence interval -6.6 to 11.6).

CONCLUSIONS

This outreach intervention promoting cholesterol screening was ineffective. Interventions that attempt to minimize barriers to cholesterol screening on multiple fronts and that are more compelling to patients are needed.

Colorectal Cancer Screening Rates at Community Health Centers that Use Electronic Health Records: A Cross Sectional Study

BACKGROUND

This study was conducted to validate use of electronic health record (EHR) data for measuring colorectal cancer (CRC) screening rates at community health centers (CHCs).

METHODS

Electronic health records were queried to assess screening via colonoscopy, flexible sigmoidoscopy, or fecal occult blood testing (FOBT) in 2011.

RESULTS

Multiple iterations were required to maximize query accuracy. Manual chart reviews, stratified by screening modality, confirmed query results for 112 of 113 (99.1%) reviewed colonoscopies, 110 of 110 (100%) reviewed FOBTs, and 111 of 120 (92.5%) unscreened patients. At participating CHCs, CRC screening rates ranged from 9.7% to 67.2% (median, 30.6%). Adherence to annual FOBT ranged from 3.3% to 59.0% (median, 18.6%). Most screening was done by colonoscopy.

CONCLUSIONS

Colorectal cancer screening varies substantially across CHCs. Electronic health record data can validly measure CRC screening, but repeated assessments of programming accuracy are required. Community health centers may need support to measure quality using EHR data and increase screening.

Individualized Risk Communication and Outreach for Primary Cardiovascular Disease Prevention in Community Health Centers: Randomized Trial

BACKGROUND

Many eligible primary cardiovascular disease prevention candidates are not treated with statins. Electronic health record data can identify patients with increased cardiovascular disease risk.

METHODS AND RESULTS

We performed a pragmatic randomized controlled trial at community health centers in 2 states. Participants were men aged ≥35 years and women ≥45 years, without cardiovascular disease or diabetes mellitus, and with a 10-year risk of coronary heart disease of at least 10%. The intervention group received telephone and mailed outreach, individualized based on patients' cardiovascular disease risk and uncontrolled risk factors, provided by lay health workers. Main outcomes included: documented discussion of medication treatment for cholesterol with a primary care clinician, receipt of statin prescription within 6 months, and low-density lipoprotein (LDL)-cholesterol repeated and at least 30 mg/dL lower than baseline within 1 year. Six hundred forty-six participants (328 and 318 in the intervention and control groups, respectively) were included. At 6 months, 26.8% of intervention and 11.6% of control patients had discussed cholesterol treatment with a primary care clinician (odds ratio, 2.79; [95% confidence interval, 2.25-3.46]). Statin prescribing occurred for 10.1% in the intervention group and 6.0% in the control group (odds ratio, 1.76; [95% confidence interval, 0.90-3.45]). The cholesterol outcome did not differ, and the majority of patients did not repeat lipid levels during follow-up.

CONCLUSIONS

Risk communication and lay outreach increased cholesterol treatment discussions with primary care clinicians. However, most discussions did not result in statin prescribing. For outreach to be successful, it should be combined with interventions to encourage clinicians to follow contemporary risk-based cholesterol treatment guidelines.

Colorectal cancer screening at community health centers: A survey of clinicians' attitudes, practices, and perceived barriers

Objective

Colorectal cancer (CRC) screening rates remain lower among some racial/ethnic groups and individuals with low income or educational attainment who are often cared for within community health centers (CHCs). We surveyed clinicians in a network of CHCs to understand their attitudes, practice patterns, and perceived barriers to CRC screening.

Methods

A clinician survey was conducted in 2013 within the Community Health Applied Research Network (CHARN).

Results

180 clinicians completed the survey (47.9% response rate). Participants had an average of 11.5 (SD: 9.8) years in practice, 62% were female, and 57% were physicians. The majority of respondents somewhat agreed (30.2%) or strongly agreed (57.5%) that colonoscopy was the best screening test. However, only 15.8% of respondents strongly agreed and 32.2% somewhat agreed that colonoscopy was readily available for their patients. Fecal immunochemical testing (FIT), a type of fecal occult blood test (FOBT), was viewed less favorably; 24.6% rated FIT as very effective.

Conclusions

Although there are no data showing that screening colonoscopy is superior to FIT, CHC clinicians believe colonoscopy is the best CRC screening test for their patients, despite the high prevalence of financial barriers to colonoscopy. These attitudes could be due to lack of knowledge about the evidence supporting long-term benefits of fecal occult blood testing (FOBT), lack of awareness about the improved test characteristics of FIT compared to older guaiac-based FOBT, or the absence of systems to ensure adherence to regular FOBT screening. Interventions to improve CRC screening at CHCs must address clinicians' negative attitudes towards FIT.

•

We surveyed primary care clinicians in a nationwide network of Community Health Centers.

•

The vast majority believed that colonoscopy was the best screening test for colorectal cancer.

•

However, less than half agreed that colonoscopy was readily available for their patients.

•

Fecal occult blood testing was viewed far less favorably than colonoscopy.

•

These attitudes and barriers must be overcome to improve screening and reduce disparities.

A model for evaluating the activities of a coalition-based policy action group: the case of Hermosa Vida

Scholars and clinicians are increasingly recognizing the complexity of social contexts of health and the need for multifunctioning approaches to health care problems including community- and policy-level strategies. Barriers to change in health care policy can sometimes be attributed to the actions of advocacy coalitions who operate from a limited view of "policy change." Advocates have a tendency to pressure stakeholders to mandate laws as a final resolution of a movement, often leading to failure or, worse, stigmatizing of issues. A more inclusive focus on health policy change as an ongoing process increases the efficacy of advocacy and outcomes measurement. This article presents a tool for policy action that coalition members developed through the implementation of a 3-year grant to improve the safety net for preventing childhood obesity. Scholars and policy makers developed the Policy Coalition Evaluation Tool with the intent to create a model to guide and measure efforts and outcomes of a local community-based policy coalition. The authors suggest using community-based participatory research approaches for developing a coalition-specific Policy Coalition Evaluation Tool to increase the effectiveness of advocacy groups and the documentation of coalition activities over time.

A call for further research on the impact of state-level immigration policies on public health

Arizona's Support Our Law Enforcement and Safe Neighborhoods Act, signed into law in April 2010, is already adversely affecting public health in the state. Our findings from a study on childhood obesity in Flagstaff suggest that the law changed health-seeking behaviors of residents of a predominantly Latino neighborhood by increasing fear, limiting residents' mobility, and diminishing trust of officials. These changes could exacerbate barriers to healthy living, limit access to care, and affect the overall safety of the neighborhood. Documentation of the on-the-ground impact of Arizona's law and similar state-level immigration policies is urgently needed. To inform effective policymaking, such research must be community engaged and include safety measures beyond the usual protocols.

Morinda citrifolia (noni) reduces cancer risk in current smokers by decreasing aromatic DNA adducts

Quantitative determination of aromatic DNA adducts in peripheral blood lymphocytes (PBLs) of current smokers is an useful surrogate biomarker for the evaluation of environmental carcinogen exposure or chemopreventive intervention. In this study, we examined the impact of Tahitian Noni Juice (TNJ) on the aromatic DNA adducts of PBLs, before and after a 1-mo intervention, using (32)P postlabeling assay. Of 283 enrolled, 203 smokers completed the trial. Aromatic DNA adducts levels in all participants were significantly reduced by 44.9% (P < 0.001) after drinking 1 to 4 oz of TNJ for 1 mo. Dose-dependent analyses of aromatic DNA adduct levels showed reductions of 49.7% (P < 0.001) in the 1-oz TNJ group and 37.6% (P < 0.001) in the 4-oz TNJ group. Gender-specific analyses resulted in no significant differences in the 4-oz TNJ groups. Interestingly, the 1-oz TNJ group showed a reduction of 43.1% (P < 0.001) in females compared with 56.1% (P < 0.001) in males. The results suggest that drinking 1 to 4 oz of TNJ daily may reduce the cancer risk in heavy cigarette smokers by blocking carcinogen-DNA binding or excising DNA adducts from genomic DNA.

Who is providing and who is getting asthma patient education: an analysis of 2001 National Ambulatory Medical Care Survey data

Patient education in asthma management is important; however, there is little known about the characteristics of patients receiving asthma education or how often primary care physicians provide it. The objective of the study was to identify the characteristics of patients receiving asthma education. It was a cross-sectional study using 2001 National Ambulatory Medical Care Survey data. The study included 1230 physicians providing office-based ambulatory medical care in the United States. Patients in the study (weighted n=11,279,952) were those diagnosed with asthma based on International Classification of Diseases, 9th Revision code receiving care from a pediatrician, internist or a family physician. Main and secondary outcome measures were asthma education ordered or provided. Multivariate analysis indicated that asthma patients receiving education were more likely to have office visits >20 min [odds ratio (OR) = 3.934], be seen for an acute reason (OR = 2.268), be seen in follow-up rather than an initial visit (OR = 1.780), live in rural rather than metropolitan areas (OR = 1.507), have public rather than private insurance (OR = 1.276) and be seen in privately owned practices (OR = 1.248). Bivariate analyses indicated that patients seeing family physicians were more likely than those seeing internists or pediatricians to receive education. Patient education was not uniformly provided. Family physicians provided more asthma education than either pediatricians or internists. Future research should investigate the quality of education provided.

Diagnosis and treatment of community-acquired pneumonia

Patients with community-acquired pneumonia often present with cough, fever, chills, fatigue, dyspnea, rigors, and pleuritic chest pain. When a patient presents with suspected community-acquired pneumonia, the physician should first assess the need for hospitalization using a mortality prediction tool, such as the Pneumonia Severity Index, combined with clinical judgment. Consensus guidelines from several organizations recommend empiric therapy with macrolides, fluoroquinolones, or doxycycline. Patients who are hospitalized should be switched from parenteral antibiotics to oral antibiotics after their symptoms improve, they are afebrile, and they are able to tolerate oral medications. Clinical pathways are important tools to improve care and maximize cost-effectiveness in hospitalized patients.

HRT and vitamins C and E do not improve coronary disease in women

Hormone replacement therapy (HRT) and antioxidant vitamin supplements (vitamins E and C) do not provide cardiovascular benefit for postmenopausal women with known coronary heart disease. Moreover, a potential for harm exists with each of the treatments. Therefore, neither should be prescribed specifically for cardiovascular benefit for postmenopausal women with coronary heart disease.

Treatment of hyperlipidemia

In 1995 and 1996, US adults made more than 18 million office visits for the evaluation and treatment of hyperlipidemia, including 3.4% of all visits to family physicians. Among visits to family physicians, 4.1% included measurement of cholesterol levels.(1) Overall, mean cholesterol levels decreased from 220 in 1960-1962 to 203 in 1988-1994. During the same time period, the proportion of adults with elevated total cholesterol levels (> 240) decreased from 32% to 19%.(2) Despite this progress, the availability of more effective drugs, guidelines advocating increasingly aggressive treatment, and population-wide goals established in Healthy People 2010 will continue to increase the number of patients seen by family physicians for screening, diagnosis, and treatment of hyperlipidemia.

A quality improvement curriculum for medical students

BACKGROUND

Despite frequent recommendations that quality improvement (QI) be incorporated into medical education, reports of this activity are few. A pilot project to develop and implement a curriculum on QI into a family medicine clerkship was conducted in the 1999-2000 academic year.

INTERVENTION

A five-part curriculum was developed and implemented on successive weeks of a family medicine clerkship. The curriculum involved students working alone and in small groups. After an orientation to QI principles, students performed a series of chart audits of diabetes care. They then met with QI coordinators from a local health system to review their results. Improvement recommendations were developed and presented to the clinic director. Evaluation included completion of the module, assessment of student knowledge and opinion, and interviews with the QI coordinators.

EVALUATION

Two clinic sites and 30 third-year medical (M3) students participated. Each student conducted at least two chart audits, met with the QI coordinators, and developed at least one improvement recommendation. The QI coordinators felt that students were interested in the subject but needed more training in QI principles and more faculty development. Students assessed the curriculum as being moderately effective and useful.

DISCUSSION

A curriculum in QI that involved active learning strategies was successfully implemented during a family medicine clerkship. Students viewed the curriculum as being appropriate to their learning. Future efforts should include more work on faculty development and role modeling of QI activity.

A survey of primary care physician practice patterns and adherence to acute low back problem guidelines

OBJECTIVE

This study evaluated physicians' self-reported management of acute low back problems in adults and adherence with published guidelines.

DESIGN

Self-administered written survey based on the US Agency for Health Care Policy and Research (now the Agency for Healthcare Research and Quality) guideline on acute low back problems in adults.

SETTING

A region of northern Illinois with a population around 250 000 and encompassing a medium-sized city.

PARTICIPANTS

One hundred eighty-two primary care physicians (nonpediatric) with medical staff appointments at area hospitals.

MAIN OUTCOME MEASURE

Adherence to published recommendations.

RESULTS

Eighty-seven surveys were received for a 48% response rate. Overall, survey respondents recognized 5 of 7 red flags representing serious underlying abnormality 50% or less of the time. Forty percent (35/87) of physicians provided patients with written educational material, and only 25%(22/87) indicated they evaluated motor function of the fifth lumbar nerve, the most commonly affected level in intervertebral disk disease disease. About 25% (24/87) reported routine use of plain films; and 16% (14/87), routine use of computed tomography or magnetic resonance imaging. Most oral medication use was consistent with recommendations, but many also used drugs conditionally discouraged by the guideline (muscle relaxants, 91% [79/87]; opioids, 62% [54/87]) or cautioned against (oral steroids, 45% [39/87]; antidepressants, 23% [20/87]; injection therapy, 52% [45/87]). Only 22% (19/87) of respondents used or recommended manipulation.

CONCLUSIONS

The management of patients with acute low back problems by primary care physicians differs significantly from Agency for Health Care Policy and Research guideline recommendations in several key areas that include awareness of red flags, use of medication, use of radiographic studies, the need for patient education, and the use of physical modalities. Future research should focus on the impact of guideline compliance on patient outcomes and cost-effectiveness. Arch Fam Med. 2000;9:1015-1021

Medical student evaluation of family nurse practitioners as teachers

BACKGROUND

Demands on family medicine faculty to generate clinical revenue may negatively impact the undergraduate medical education program. To minimize this possibility and better model interprofessional education, family nurse practitioners (FNPs) were hired as clinicians and teachers as part of a longitudinal family medicine clerkship. This paper reports the results of a pilot study of student evaluations of nurse practitioner teaching.

METHODS

All M3 and M4 students were asked to evaluate one of three FNPs who had precepted them multiple times during their previous year of ambulatory care practice. Two previously studied closed-ended questionnaires were used to assess quality of teaching by the FNPs. Students also responded to a series of open-ended questions.

RESULTS

Ninety-one percent of 97 students responded to the survey. Responses to the closed-ended questions as well as comments by the students and physicians were positive regarding the teaching by FNPs. The teaching skills most highly regarded by the students tended to be different than those most highly regarded in physicians.

CONCLUSIONS

This pilot study suggests FNPs can be successfully integrated into undergraduate medical education settings, offering teaching strengths that complement those of physicians. Integrating the two professions in a family medicine clerkship may prove beneficial to students and expand departmental teaching resources without further straining finances. Efforts at evaluating the teaching contributions of FNPs at other institutions are needed to substantiate the present study results.

Teaching medical students about over-the-counter medications

OBJECTIVES

Over-the-counter (OTC) medications account for over half of US drug expenses but have received little attention in medical school education. This pilot study evaluated student attitudes and knowledge in connection with a new curriculum in an ambulatory teaching clinic.

DESIGN

Learning objectives were developed for six categories of OTC medications and students taught each other under the direction of a clinical pharmacist and family physician. Learning was undertaken in small groups and a site visit to a pharmacy was included. A 25-question test of knowledge was administered before and 6 months after the project, and student attitudes were assessed.

SETTING

The sessions were taught as part of a longitudinal family medicine clerkship at an ambulatory care teaching clinic, Rockford, Illinois, USA.

SUBJECTS

Twenty third-year medical students took the pre-test and attended the educational sessions; 19 completed the post-test and 16 completed the attitudinal survey.

RESULTS

The mean pre-test score of 49% improved to 67% on the post-test (p<0.001). On the survey, 94% found the material useful and 88% liked the small group learning, but only 60% felt the pharmacy trip was worthwhile.

CONCLUSION

In this study, medical students found teaching about OTC medications to be useful and showed significant improvement on a fund of knowledge test.

Use of computerized prenatal interviews for assessing high-risk behaviors among American Indians

The objectives of this study were to determine the prevalence of risk factors for adverse pregnancy outcomes among American Indians and to compare self-reported information collected under two computer interview conditions: an "anonymous" (N = 183) versus a "confidential" (N = 210) format. Results indicated that under 10% in both groups reported either use of cigarettes or other drugs of abuse, 16% reported risky drinking, 39% reported psychological distress, and 8% reported physical abuse during the current pregnancy. We concluded that confidential computer interviews were appropriate vehicles for obtaining risk information in this population.
