A nurse practitioner intervention to increase breast and cervical cancer screening for poor,elderly black women

Objective: To compare nurse practitioner (NP) and physician rates of breast and cervical cancer screening among poor, elderly black women. Design: A quasi-experimental design was used to compare pre- and postintervention annual screening rates. Rates were determined by medical record audits. Setting: Two urban public hospital primary care clinics served as the study sites. Patients: All women aged 65 years or more were eligible to participate. Interventions: Women were offered screening by a NP during a routine visit in the intervention site; a physician reminder system was used in the control site. Main results: Baseline annual screening rates were comparable in the two study sites. At the end of the study period, rates were significantly higher in the NP site, compared with the control. In the NP clinic, the annual rate of Pap tests increased to 56.9% from the baseline of 17.8%, and mammographies increased to 40% from 18.3%. In comparison, rates remained low in the control site, increasing only to 18.2% of women receiving Pap tests from a baseline of 11.8%, and remaining at 18% for mammography. Conclusions: Use of a NP to deliver same-day screening is an effective strategy to target poor, elderly black women for breast and cervical cancer screening. However, even with the substantial increases in rates obtained with the NP intervention, screening in this vulnerable population remains below nationally targeted levels.

Promoting cancer screening. A randomized, controlled trial of three interventions

To determine effective methods of promoting routine cancer screening, we randomly assigned 62 internal medicine residents to receive cancer screening reminders (computer-generated lists of overdue tests at patients' visits), audit with feedback (monthly seminars about screening, with feedback about their performance rates), or no intervention (controls). Half of the residents in each group also were randomized to receive patient education (patients received literature and notices of overdue tests). We reviewed a sample of each physician's medical records to assess performance of seven tests during 9-month periods before and after initiating the interventions. Cancer screening reminders increased performance of six of seven tests; audit with feedback, four of seven tests; and patient education, one of two targeted breast cancer screening tests. The results indicate that the cancer screening reminders strategy was the most effective in promoting the performance of routine cancer screening tests.     

Colorectal cancer screening

Colorectal cancer is one of the most common malignancies in Australia, and screening to detect it an earlier stage is cost‐effective. Furthermore, detection and removal of precursor polyps can reduce incidence. Currently, there are limited data to determine the screening rate in Australia, but it is certainly lower than the 80% screening rate considered desirable. Whether colonoscopy is used as the screening test or to follow up positive results of an initial non‐invasive test, it plays a fundamental role. Despite high sensitivity and specificity, it is expensive and invasive with measurable risk and is not acceptable as an initial test to many participants. It does not provide complete protection, and interval cancers between planned colonoscopies are associated with proximal location, origin in sessile serrated adenomas and operator‐dependent factors. An essential component of colorectal screening is the measurement of colonoscopy quality indicators, such as caecal intubation and adenoma detection rates, which are known to be associated with the rate of interval cancer. The non‐invasive screening test currently recommended in Australia is biennial testing for faecal occult blood between the ages of 50 and 75 using a faecal immunochemical test, with positives evaluated by colonoscopy. This is provided through the National Bowel Cancer Screening Programme, currently for those at the ages of 50, 55, 60 and 65 years, with full implementation of biennial screening by 2020. To improve screening in Australia, the most fruitful approach may be to acknowledge that there is a choice of screening tests and to focus on the goal of improving overall participation rate and being able to measure this.     

Barriers to A1C testing among a managed care population

PURPOSE: The purpose of this study is to explore reasons adults with diabetes do not receive at least 2 A1C tests per year as recommended by the American Diabetes Association (ADA). METHODS: ConnectiCare, a regional managed care company based in Farmington, Connecticut, identified adult members with diabetes who did not have a medical claim for an A1C laboratory test from their physician. A questionnaire was sent to 740 randomly selected members asking them to report the number of A1C tests they received in the past 12 months and reasons for not receiving the number of tests recommended by the ADA. After sending an automated telephone reminder to nonrespondents, a 26% (n = 192) response rate was achieved. RESULTS: Thirty-three percent of respondents (n = 63) reported having diabetes and receiving fewer than 2 A1C tests in the past year. Respondents were equally divided between men and women, with a mean age of 58 years. The primary reasons given for not obtaining at least 2 A1C tests as recommended by the ADA were that respondents were unaware that the test is recommended (49%), not informed of the need for the test by their physician (38%), never heard of the A1C test (33%), and not seen regularly by their physician (19%). CONCLUSIONS: Diabetes self-management education remains an important means of encouraging adherence to important ADA recommendations such as regular A1C testing. Barriers to A1C testing can be addressed in multiple settings, including individual and group education, disease management programs, and physician education.     

Measuring resident physicians’ performance of preventive care

BACKGROUND: The Accreditation Council for Graduate Medical Education has suggested various methods for evaluation of practice-based learning and improvement competency, but data on implementation of these methods are limited. OBJECTIVE: To compare medical record review and patient surveys on evaluating physician performance in preventive services in an outpatient resident clinic. DESIGN: Within an ongoing quality improvement project, we collected baseline performance data on preventive services provided for patients at the University of Alabama at Birmingham (UAB) Internal Medicine Residents' ambulatory clinic. PARTICIPANTS: Seventy internal medicine and medicine-pediatrics residents from the UAB Internal Medicine Residency program. MEASUREMENTS: Resident- and clinic-level comparisons of aggregated patient survey and chart documentation rates of (1) screening for smoking status, (2) advising smokers to quit, (3) cholesterol screening, (4) mammography screening, and (5) pneumonia vaccination. RESULTS: Six hundred and fifty-nine patient surveys and 761 charts were abstracted. At the clinic level, rates for screening of smoking status, recommending mammogram, and for cholesterol screening were similar (difference <5%) between the 2 methods. Higher rates for pneumonia vaccination (76% vs 67%) and advice to quit smoking (66% vs 52%) were seen on medical record review versus patient surveys. However, within-resident (N=70) comparison of 2 methods of estimating screening rates contained significant variability. The cost of medical record review was substantially higher ($107 vs $17/physician). CONCLUSIONS: Medical record review and patient surveys provided similar rates for selected preventive health measures at the clinic level, with the exception of pneumonia vaccination and advising to quit smoking. A large variation among individual resident providers was noted.     

Successful colorectal cancer screening starts with primary care

Colorectal cancer screening is effective. Screening rates remain low, but that will change. All guidelines now recommend colorectal cancer screening, the value of screening is being promoted in the popular media, and insurers are beginning to pay for screening tests. For screening programs to be successful, good intentions must be backed by reminder systems, readily available patient information, and other changes in office practice. Currently recommended screening options accommodate a broad range of patient preferences and save lives, but none is ideal. Newer tests, such as virtual colonoscopy and stool-based DNA tests, will help if they offer greater sensitivity, specificity, or patient acceptability than current screening options.     

Mammography and Papanicolaou smear use by elderly poor black women. The Harlem Study Team.

OBJECTIVE: To describe factors related to the use of mammography and Papanicolaou smears in low-income women aged 65 or more years to guide development of future interventions. DESIGN: A cross-sectional survey. SETTING AND PATIENTS: Elderly Black women attending a public hospital medical clinic. MEASUREMENTS: Information obtained in a face-to-face interview of a random sample of patients. RESULTS: Four-hundred and forty-five women (94%) consented to be interviewed; 74% reported a mammogram, and 85% reported a Papanicolaou smear in the past, although these early-detection tests were not obtained with any regularity after age 65. Concordance between self-reported screening use and blind chart review was more than 90%. The major reasons for non-use of both screening tests were that a physician hadn't recommended them or that the women didn't know they needed them. Levels of knowledge about breast and cervix cancer were low; 68% believed bumping or bruising the breast caused cancer, and only 25% knew that cancer risk increased with advancing age. In logistic regression models, health status, provider type, perceived benefit, life satisfaction, and knowledge of test intervals were each significantly associated with mammogram use. Age, health status, education, perceived susceptibility and benefit, life satisfaction, and knowledge of test intervals were independently related to Pap use (P < .05). CONCLUSION: This study illustrates that elderly, poor, minority women who are regular health-care users do use mammography and Pap smear screening services. Incorporating screening into routine primary care and physician and patient education could enhance the use of early cancer detection procedures in this age group.     

Barriers of and Facilitators to Physician Recommendation of Colorectal Cancer Screening

BACKGROUND Colorectal cancer screening (CRCS) has been demonstrated to be effective and is consistently recommended by clinical practice guidelines. However, only slightly over half of all Americans have ever been screened. Patients cite physician recommendation as the most important motivator of screening. This study explored the barriers of and facilitators to physician recommendation of CRCS. METHODS A 3-component qualitative study to explore the barriers of and facilitators to physician recommendation of CRCS: in-depth, semistructured interviews with 29 purposively sampled, community- and academic-based primary care physicians; chart-stimulated recall, a technique that utilizes patient charts to probe physician recall and provide context about the barriers of and facilitators to physician recommendation of CRCS during actual clinic encounters; and focus groups with 18 academic primary care physicians. Grounded theory techniques of analysis were used. RESULTS All the participating physicians were aware of and recommended CRCS. The overwhelmingly preferred test was colonoscopy. Barriers of physician recommendation of CRCS included patient comorbidities, prior patient refusal of screening, physician forgetfulness, acute care visits, lack of time, and lack of reminder systems and test tracking systems. Facilitators to physician recommendation of CRCS included patient request, patient age 50–59, physician positive attitudes about CRCS, physician prioritization of screening, visits devoted to preventive health, reminders, and incentives. CONCLUSION There are multiple physician, patient, and system barriers to recommending CRCS. Thus, interventions may need to target barriers at multiple levels to successfully increase physician recommendation of CRCS. The results of this paper were previously presented at the 27th Annual Meeting of the Society of General Internal Medicine, May 15, 2004, Chicago, IL. Jamin S.

Effect of Medicare coverage on use of invasive colorectal cancer screening tests

BACKGROUND: Colorectal cancer is the second leading cause of cancer death in the United States. Screening for colorectal cancer is now widely recommended but underused. Lack of insurance coverage for screening tests may be one reason patients do not undergo these procedures. OBJECTIVE: To determine the effect of Medicare reimbursement on utilization rates of invasive screening tests. Use of fecal occult blood testing was not studied before 1998. METHODS: We performed a retrospective analysis of ambulatory claims data for Washington State Medicare beneficiaries in 1994, 1995, and 1998. We determined the proportion of patients undergoing diagnostic and screening flexible sigmoidoscopy, colonoscopy, or double-contrast barium enema in 1994, 1995, and 1998 and the proportion receiving fecal occult blood testing in 1998. RESULTS: Use of diagnostic and screening colon tests was low in all years. Fewer than 6% of beneficiaries received any colon test, and fewer than 4% received a screening test. Although more patients underwent diagnostic testing after Medicare coverage began, use of screening tests did not significantly change (odds ratio, 0.99; 95% confidence interval, 0.97-1.01 comparing 1994 and 1998 [P =.33]). Women, individuals older than 80 years, and nonwhite patients were statistically significantly less likely to be screened in all 3 years (P<.001). In 1998, fewer than 7% of patients underwent fecal occult blood testing, with men and nonwhites statistically significantly less likely to have this test (P<.001). CONCLUSIONS: Colorectal cancer screening tests are underused in the Washington State Medicare population, and insurance coverage for these tests did not substantially affect utilization rates in the period studied.     

Factors Associated with Osteoporosis Screening and Recommendations for Osteoporosis Screening in Older Adults

BACKGROUND  Osteoporosis screening rates are low, and it is unclear which patient factors are associated with screening and physician recommendations for screening. OBJECTIVE  To identify patient characteristics associated with osteoporosis screening recommendations and receipt of screening in older adults. DESIGN  Cross-sectional mailed survey. PARTICIPANTS  Women and men ≥60 years old living in or near western Pennsylvania. MEASUREMENTS  Sociodemographic characteristics and osteoporosis-related data, including risk factors, physician recommendations for screening, and receipt of screening. Multivariable logistic regression analyses were performed to determine odds ratios for receipt of screening and screening recommendations for individuals with particular osteoporosis risk factors, adjusting for sociodemographic and other risk factors. RESULTS  Surveys were completed by 1,268 of the 1,830 adults to whom surveys were mailed (69.3%). Most respondents were white (92.9%), female (58.7%), and believed they were in good to excellent health (88.2%). Only 47.6% said their physician recommended osteoporosis screening, and 62.6% of all respondents reported being screened. Screening recommendations were less likely for older respondents than younger ones (OR, 0.87 per 5-year increase in age; 95% CI, 0.77–0.97). Individuals with osteoporosis risk factors of a history of oral steroid use for >1 month, height loss >2.54 cm, or history of low-trauma fracture were no more likely to report screening recommendations than individuals without these characteristics. Receipt of screening was no more likely for more elderly respondents or respondents with a history of oral steroid use for >1 month than for respondents without these characteristics. CONCLUSIONS  Individuals with several known osteoporosis risk factors are not being sufficiently targeted for screening.     

Perspectives of colorectal cancer screening in Germany 2009

Adequate screening methods can decrease colorectal cancer (CRC) mortality. The guaiac test for fecal occult-blood (FOBT) is part of the German CRC Screening Program since 1970 and has evidence level Ia. In randomized multicenter-studies FOBT has an average sensitivity of 24% and decreases CRC mortality up to 30%. Immunological tests for human haemoglobin (iFOBT) show better performance characteristics than guaiac FOBT, with augmented sensitivity and specificity. However, the single tests show wide differences in diagnostic performance and iFOBT is not yet covered by insurance companies although it should replace the guaiac test for CRC screening. Visual colonoscopy, which was introduced to the German National Cancer Screening Program in 2002, is the gold standard for the diagnosis of colorectal neoplasia. From 2003 to 2007 more than 2.8 million examinations have been documented in Germany. The prevalence of adenomas is around 20% and of CRC about 0.7% to 1.0% of the screenings. Seventy percent of the carcinomas detected during screening are in an early stage (UICC I and II). Furthermore, screening colonoscopy is a cost saving procedure with a low complication rate (0.25% overall). Insurance companies save 216€ for each screening colonoscopy mainly by prevention of neoplasia due to polypectomy. In Germany, virtual colonography by computed tomography (CT) or magnetic resonance imaging still lacks standardization of the hard and software. In experienced centres the sensitivity for CRC and large polyps of CT colonography is comparable to colonoscopy but in meta-analyses the ranking is lower. New technologies like computer-aided colonoscopies with sheath or double balloon techniques are coming up as well as capsule colonoscopy, which sensitivity for large polyps is about 70%. Advised by his physician, the patient can choose his most acceptable examination method from this whole set of screening tools.     

Syndrome of recommended patient

"Syndrome of recommended patient" is manifested as the presence of numerous unexpected and unusual complications in patients that the treating physician is trying to give a better assistance. Even assuming that a few complications may appear by chance, there are several factors from daily clinical practice that facilitate the presence of such a syndrome, and some of them can be corrected in order to reduce its incidence. All of them come from the change on daily clinical practice on these patients, as if they do not fit for the attention provided for other people. These factors favouring the presence of this syndrome come from: patients' attitude, inefficient use of health resources, absence of an adequate register of clinical data and change in usual clinical practice on interpretation of diagnostic tests as well as in the indication of treatment of these patients. The best way to prevent this "syndrome of recommended patient" is to maintain, even within these patients, an attitude based on solid clinical knowledge and to follow up the same clinical rules accepted for other patients.     

Using Quality Improvement Techniques to Increase Colon Cancer Screening

Screening has been shown to be effective and cost-effective in reducing the incidence of, and mortality from, colorectal cancer. Despite its demonstrated efficacy, colon cancer screening remains underused, with fewer than 60% of age-eligible adults reporting being up to date with recommended screening tests. Several factors account for the low rates of utilization, including patient, provider and system-related issues. Several interventions have been shown to be effective in overcoming these barriers, including the use of patient decision aids. Patient decision aids are tools designed to provide information to patients about screening options, help them consider the pros and cons of the alternatives, and assist them to reach a decision consistent with their values. The use of decision aids in clinical practice can increase screening rates by up to 14 percentage points. Mailing the decision aids to patients in advance of office visits appears to be a cost-effective means of implementation.     

The relation of autopsy rate to physicians' beliefs and recommendations regarding autopsy

PURPOSE: Multiple factors have affected the decline in autopsy rates. Our goal was to determine the relation of physicians' recommendations regarding autopsy, as well as patient and surrogate decision-maker characteristics, to autopsy performance. METHODS: We assessed measures related to autopsy performance using data from two teaching institutions in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments. We included patients who had died within 6 months of their index hospitalization and for whom information was available on autopsy performance, physicians' response to questions about autopsy, and interviews with surrogate decision makers about autopsy performance. We assessed the association between autopsy performance and the strength of a physician's recommendation for autopsy, adjusting for patient, surrogate, and physician characteristics. RESULTS: Of the 680 patients who died, 59% (n = 402) met our inclusion criteria. Based on physician and surrogate responses, the expected autopsy rate was 42% while the actual autopsy rate was 23%. The autopsy rate was higher when the physician's recommendation for autopsy was strong or very strong at the time of death compared with when autopsy was not recommended strongly or not at all (P <0.001). The strength of the physician's postmortem recommendation was independently associated with autopsy performance after adjusting for patient, surrogate, and physician characteristics (P <0.001). CONCLUSION: Autopsies are less likely to be performed when not recommended strongly or not at all. Training physicians (or others) how to recommend autopsies may increase autopsy rates.     

Health promotion and disease prevention in the elderly. Comparison of house staff and attending physician attitudes and practices

The purpose of this study was to evaluate and compare attending physician and house staff attitudes and practices regarding health promotion and disease prevention in the elderly. Seventy-four physicians (38 house staff and 36 attending physicians) were surveyed from four sites in Pittsburgh, Pa, regarding their agreement with recommendations of the American Cancer Society and the Canadian Task Force. Two hundred fifty patients were interviewed and their charts were reviewed for performance of the recommendations. In all patients, physicians agreed highly with the American Cancer Society and the Canadian Task Force recommendations (agreement, 80% to 100%), with the exception of proctoscopy and thyroid examinations. Physicians performed screening procedures much less frequently. House staff and attending physicians differed regarding their attitudes about prevention. House staff felt the need for more formal instruction and were more positive regarding a healthy life-style and commitment to health promotion. The significant predictors of tests (defined as either examination or test ordered by a physician) were presence of a checklist, site of practice, and physician status. A logistic regression analysis was performed; however, this model could not entirely explain the variations found. Although physicians agreed with recommendations for screening, the attending physicians and house staff (particularly attending physicians) were less likely to perform the screening, especially in the elderly.     

Screening des kolorektalen Karzinoms

Colorectal cancer is common and suitable for screening. There is general agreement that screening for colorectal cancer in the asymptomatic population without familial risk should begin at age 50. The different screening methods can be separated into methods that mainly detect cancers (fecal occult blood tests, genetic stool tests, blood tests, and the M2-PK test) and methods that diagnose cancers and polyps (colonoscopy, sigmoidoscopy, CT/MRI colonography, and colon capsule endoscopy). Endoscopic methods enable detection and treatment of preneoplastic adenomas and, thus, make cancer prevention possible. In the current German S3 guideline, colonoscopy is recommended as the preferred screening test. For people unwilling to undergo endoscopic screening, the fecal occult blood test is an alternative. Colonoscopy has been part of the German Cancer Screening Program since 2002.     

Comparative Effectiveness of Audit-Feedback Versus Additional Physician Communication Training to Improve Cancer Screening for Patients with Limited Health Literacy

BACKGROUND

We designed a continuing medical education (CME) program to teach primary care physicians (PCP) how to engage in cancer risk communication and shared decision making with patients who have limited health literacy (HL).

OBJECTIVE

We evaluated whether training PCPs, in addition to audit-feedback, improves their communication behaviors and increases cancer screening among patients with limited HL to a greater extent than only providing clinical performance feedback.

DESIGN

Four-year cluster randomized controlled trial.

PARTICIPANTS

Eighteen PCPs and 168 patients with limited HL who were overdue for colorectal/breast/cervical cancer screening.

INTERVENTIONS

Communication intervention PCPs received skills training that included standardized patient (SP) feedback on counseling behaviors. All PCPs underwent chart audits of patients’ screening status semiannually up to 24 months and received two annual performance feedback reports.

MAIN MEASURES

PCPs experienced three unannounced SP encounters during which SPs rated PCP communication behaviors. We examined between-group differences in changes in SP ratings and patient knowledge of cancer screening guidelines over 12 months; and changes in patient cancer screening rates over 24 months.

KEY RESULTS

There were no group differences in SP ratings of physician communication at baseline. At follow-up, communication intervention PCPs were rated higher in general communication about cancer risks and shared decision making related to colorectal cancer screening compared to PCPs who only received performance feedback. Screening rates increased among patients of PCPs in both groups; however, there were no between-group differences in screening rates except for mammography. The communication intervention did not improve patient cancer screening knowledge.

CONCLUSION

Compared to audit and feedback alone, including PCP communication training increases PCP patient-centered counseling behaviors, but not cancer screening among patients with limited HL. Larger studies must be conducted to determine whether lack of changes in cancer screening were due to clinic/patient sample size versus ineffectiveness of communication training to change outcomes.     

Colorectal cancer screening

Colorectal cancer (CRC) is the third most common cause of cancer death worldwide and a major health problem. In this review, the different approaches for CRC screening will be outlined with emphasis on evidence-based medicine. Evidence from randomized trials on the effectiveness of CRC screening is summarized. Several screening tools for CRC are available. They can be categorized according to their mode of action: early detection tools such as the faecal occult blood test (FOBT) and cancer prevention tools such as flexible sigmoidoscopy and colonoscopy. Meta-analyses of randomized trials show that FOBT screening reduces CRC mortality by 16% (risk ratio 0.84; 95% confidence interval (CI) 0.78-0.9) compared with 30% (risk ratio 0.7; 95% CI 0.6-0.81) for flexible sigmoidoscopy screening. FOBT screening is cheap and noninvasive, but results in large numbers of false-positive tests and needs to be repeated frequently. Flexible sigmoidoscopy is more invasive, but is effective for once-only screening. Although colonoscopy screening is used in some countries, no randomized trials have been conducted to estimate its benefit, and therefore, it should not be recommended at the present time. Faecal occult blood test and flexible sigmoidoscopy are the two CRC screening tools that can be recommended as they have been proven to reduce CRC mortality. Colonoscopy has the potential to be superior to FOBT and flexible sigmoidoscopy, but needs to be evaluated in randomized trials before any recommendation can be provided.     

Primer: Applying the new postpolypectomy surveillance guidelines in clinical practice

Colonoscopy is being increasingly used for colorectal cancer screening, which has resulted in a growing cohort of patients who have polyps that require postpolypectomy surveillance. Risk stratification enables postpolypectomy surveillance to be tailored to individual patient needs, and this is one of the fundamental points emphasized by the unified US Multi-Society Task Force on Colorectal Cancer and the American Cancer Society (USMSTF-ACS) guidelines. Most patients do not require intensive surveillance; those patients who have one or two small (<1 cm) adenomas can safely undergo repeat colonoscopy after 5-10 years. Consensus guidelines that merge the recommendations of all societies are more user-friendly than individual guidelines, decrease confusion, and eliminate conflicting recommendations that are a barrier to guideline uptake. Nonetheless, studies have shown that specialists and nonspecialists overutilize colonoscopy for postpolypectomy surveillance, which places a large burden on already strained resources. Barriers to guideline implementation include factors involving the patient, physician, and health-care system. Physician education and widespread implementation of continuous quality improvement programs are required to bridge the gap between the guidelines and their clinical application.
