CDC-funded intervention research aimed at promoting colorectal cancer screening in communities.

BACKGROUND: Although strong scientific evidence has shown that screening for colorectal cancer saves lives, most U.S. adults who are at the recommended age are not being screened. Prior studies suggest that barriers to routine screening vary by race, ethnicity, socioeconomic status, urban/rural residence, health insurance status, and factors related to health care providers and the health care environment. Relatively few studies, however, have identified and tested intervention approaches to promote routine colorectal cancer screening among diverse populations. METHODS: The Division of Cancer Prevention and Control at CDC has funded ongoing projects to develop and test interventions to promote routine colorectal cancer screening among medically underserved populations in Appalachia, the Lower Rio Grande Valley in Texas, the High Plains region of Colorado, and other U.S. communities. RESULTS: This article provides an overview of colorectal cancer screening intervention studies currently funded by CDC that focus on a wide range of populations, including medically underserved persons who live in predominately rural areas, Hispanic and non-Hispanic persons, urban African Americans, persons with low health literacy, and persons enrolled in managed care organizations. CONCLUSIONS: These CDC-funded intervention research projects are likely to contribute importantly to evidence about what works to promote colorectal cancer screening in diverse U.S. communities. .

Evaluating sample medications in primary care: a practice-based research network study.

BACKGROUND: No reports have objectively evaluated safety of samples in primary care practices. A study was conducted to determine adherence to the Institute for Safe Medication Practices (ISMP) recommendations for safe distribution of medication samples to minimize medication errors. METHODS: In 2004, 17 urban and rural primary care practices participated in a two-phase observational study: (1) a site visit to collect inventory data and perform assessment of medication sample dispensing procedures and (2) a survey questionnaire for providers and patients upon sample medication provision. RESULTS: No practices were compliant with all seven ISMP recommendations. Twelve of 17 practices had policies for sample medication dispensing, and 7 had policies for labeling. Sample medication use was evaluated for 585 office visits and 27 patient surveys. Fifty-eight sample medications were dispensed during 55 of 585 patient visits. Common reasons for using sample medications included availability and need for a short-term trial for a chronic medication. Verbal communication only was provided most of the time for patient education regarding appropriate sample medication use and side effects. DISCUSSION: Primary care practices in this research network did not follow safe and appropriate sample medication dispensing procedures as outlined by ISMP. Both labeling and patient instructions were inadequate and may increase the risk for medication errors.

Sports-related injuries in the United States: who gets care and who does not.

OBJECTIVE: To describe the pattern of sports-related injuries (SRIs), healthcare obtained for these injuries, and factors associated with obtaining healthcare. DESIGN AND SETTING: Retrospective analysis of the adult subgroup within the Medical Expenditures Panel Survey dataset from 1996 to 2001, which is weighted to represent all noninstitutionalized US residents. PARTICIPANTS: Survey participants (2996) aged 0 to 64 years reporting an SRI. MAIN OUTCOME MEASUREMENT: Whether healthcare was obtained for an SRI. RESULTS: A weighted estimate of 6.7 million individuals reported an SRI annually. Two million individuals (30%) did not obtain healthcare for an SRI. Twenty-four percent of those with "serious" injuries did not obtain healthcare. Predictors of obtaining healthcare include the following: an upper extremity injury [adjusted odds ratio (OR) 1.57, 95% confidence intervals (CI): 1.17, 2.10]; a "very or somewhat serious" injury (adjusted OR 1.64, 95% CI 1.24, 2.17); and one SRI versus >1 SRI (adjusted OR 1.37, 95% CI: 1.06, 1.78). Predictors of not obtaining healthcare for an SRI include the following: Black race (adjusted OR 0.59, 95%CI: 0.44, 0.79); no health insurance (adjusted OR 0.45, 95%CI: 0.33, 0.63); and no usual source of care (adjusted OR 0.71, 95% CI: 0.56, 0.91). CONCLUSIONS: SRIs are common and often patients do not obtain healthcare for these injuries. Among Americans with an SRI, those who are Black, and those who lack insurance or a usual source of care, are at risk for not obtaining care for an SRI. Not obtaining healthcare and lacking knowledge about the consequences of sports injury may lead to unnecessary, additional morbidity and cost. Education targeted at these groups, at their physicians, and at policymakers may help reduce untreated SRIs.

Barriers to quality care for dying patients in rural communities.

CONTEXT: Barriers to providing optimal palliative care in rural communities are not well understood. PURPOSE: To identify health care personnel's perceptions of the care provided to dying patients in rural Kansas and Colorado and to identify barriers to providing optimal care. METHODS: An anonymous self-administered survey was sent to health care personnel throughout 2 rural practice-based research networks. Targeted personnel included clinicians, nurses, medical assistants, chaplains, social workers, administrators, and ancillary staff, who worked at hospice organizations, hospitals, ambulatory clinics, public health agencies, home health agencies, and nursing homes. FINDINGS: Results from 363 completed surveys indicated that most health care personnel were satisfied with the palliative care being provided in their health care facilities (84%) and that most were comfortable helping dying patients transition from a curative to a palliative focus of care (87%). Yet, many reported that the palliative care provided could be improved and many reported that family members' avoidance of issues around dying (60%) was a barrier to providing optimal care in rural health care facilities. CONCLUSIONS: Findings suggest that health care personnel perceive they are effective at providing palliative care in their rural health care facilities, yet face barriers to providing optimal end-of-life care. Results of this study suggest that differences in training and experience may influence health care personnel's perceptions of the existing barriers. It may be important in rural areas to customize interventions to both the professional role and the site of care.

Action or inaction? Decision making in patients with diabetes and elevated blood pressure in primary care.

OBJECTIVE: Hypertension increases micro- and macrovascular complications of diabetes. The goal for blood pressure is <130/80 mmHg. In primary care, however, blood pressure in many patients exceeds this goal. In this study, we evaluated the clinical decision-making process when a patient with diabetes presents with elevated blood pressure. RESEARCH DESIGN AND METHODS: Twenty-six primary care practices in two practice-based research networks in Colorado participated. Questionnaires were completed after each encounter with an adult with type 2 diabetes. Data obtained from the survey included 1) demographic information, 2) blood pressure results, 3) action taken, 4) type of action if action was taken, and 5) reasons for inaction if action was not taken. Bivariate and multivariate analyses were performed to identify predictors of action. RESULTS: Completed surveys totaled 778. Blood pressure was 130/74 +/- 18.8/12.0 mmHg (mean +/- SD). Sixty-two percent of patients exceeded goals. Action was taken to lower blood pressure in 34.9% of those. Predictors of action were 1) blood pressure level, 2) total number of medicines the patient was taking, and 3) patient already taking medicines for blood pressure. As blood pressure rose, providers attributed inaction more often to "competing demands" and reasons other than "blood pressure being at or near goal." CONCLUSIONS: No evidence was found for patterns of poor care among primary care physicians. Providers balance the clinical circumstances, including how elevated the blood pressure is, and issues of polypharmacy, medication side effects, and costs when determining the best course of action. Knowledge deficit is not a common cause of inaction.

Birth outcomes in Colorado's undocumented immigrant population.

BACKGROUND: The birth outcomes of undocumented women have not been systematically studied on a large scale. The growing number of undocumented women giving birth in the United States has important implications for clinical care and public health policy. The objective of this study was to describe birth outcomes of undocumented immigrants in Colorado. METHODS: Retrospective descriptive study of singleton births to 5961 undocumented women using birth certificate data for 1998-1999. RESULTS: Undocumented mothers were younger, less educated, and more likely to be single. They had higher rates of anemia, were less likely to gain enough weight, and less likely to receive early prenatal care. They were much less likely to use alcohol or tobacco. Undocumented women had a lower rate of low birth weight (5.3% v 6.5%, P < .001) or preterm infants (12.9% v 14.5%; p = .001). Undocumented women experienced higher rates of labor complications including excessive bleeding (2.3% v 0.8%, p < .001) and fetal distress (8.7% v 3.6%, p < .001). CONCLUSION: Undocumented women have lower rates of preterm delivery and low birth weight infants, but higher rates of pregnancy related risk factors. Higher prevalence of some risk factors which are amenable to medical intervention reveals the need for improved prenatal care in this group.

Missing clinical information during primary care visits.

CONTEXT: The coordinating function of primary care is information-intensive and may be impeded by missing clinical information. However, missing clinical information has not been explicitly investigated in the primary care setting. OBJECTIVE: To describe primary care clinicians' reports of missing clinical information. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional survey conducted in 32 primary care clinics within State Networks of Colorado Ambulatory Practices and Partners (SNOCAP), a consortium of practice-based research networks participating in the Applied Strategies for Improving Patient Safety medical error reporting study. Two hundred fifty-three clinicians were surveyed about 1614 patient visits between May and December 2003. For every visit during 1 half-day session, each clinician completed a questionnaire about patient and visit characteristics and stated whether important clinical information had been missing. Clinician characteristics were also recorded. MAIN OUTCOME MEASURES: Reports of missing clinical information frequency, type, and presumed location; perceived likelihood of adverse effects, delays in care, and additional services; and time spent looking for missing information. Multivariate analysis was conducted to assess the relationship of missing information to patient, visit, or clinician characteristics, adjusting for potential confounders and effects of clustering. RESULTS: Clinicians reported missing clinical information in 13.6% of visits; missing information included laboratory results (6.1% of all visits), letters/dictation (5.4%), radiology results (3.8%), history and physical examination (3.7%), and medications (3.2%). Missing clinical information was frequently reported to be located outside their clinical system but within the United States (52.3%), to be at least somewhat likely to adversely affect patients (44%), and to potentially result in delayed care or additional services (59.5%). Significant time was reportedly spent unsuccessfully searching for missing clinical information (5-10 minutes, 25.6%; >10 minutes, 10.4%). After adjustment, reported missing clinical information was more likely when patients were recent immigrants (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.06-2.99), new patients (OR, 2.39; 95% CI, 1.70-3.35), or had multiple medical problems compared with no problems (1 problem: OR, 1.09; 95% CI, 0.69-1.73; 2-5 problems: OR, 1.87; 95% CI, 1.21-2.89; >5 problems: OR, 2.78; 95% CI, 1.61-4.80). Missing clinical information was less likely in rural practices (OR, 0.52; 95% CI, 0.29-0.92) and when individual clinicians reported having full electronic records (OR, 0.40; 95% CI, 0.17-0.94). CONCLUSIONS: Primary care clinicians report that missing clinical information is common, multifaceted, likely to consume time and other resources, and may adversely affect patients. Additional research on missing information is needed to focus on validating clinicians' perceptions and on conducting prospective studies of its causes and sequelae.

Validation of the EQ-5D quality of life instrument in patients after myocardial infarction.

BACKGROUND: We assessed cross-sectional validity of EQ-5D after myocardial infarction (MI). METHODS: We compared EQ-5D, SF-36, quality of life After MI (QLMI), and Canadian Cardiovascular Society Anginal Classification (CCSG) scores. Correlation and regression techniques were used to assess convergent validity. SF-36 and alternate Rand-36 scoring were compared. CCSG class was used to evaluate discriminative validity and clinical difference in health state scores. RESULTS: Of 99 patients: mean age 64; median 176.5 days post-MI; 80% had one MI; 74% were CCSG I. 1/3 to 1/2 reported mobility, self-care, pain, and emotional difficulties on EQ-5D. Median health state was 0.73. EQ-5D and SF-36 (or Rand-36) strongly correlate in overall health (0.75), emotional health (0.75), pain (0.68), and activity/functional (0.5-0.63). EQ-5D and QLMI strongly correlate in activities/self esteem (0.56), emotional health (0.64), anxiety/ depression--restriction (0.53), and overall health (0.5-0.57). EQ-5D self-care correlates weakly with all domains. Domain scores from each general instrument contributed to each other's overall health score (adjusted R2 0.61-0.69) and to disease specific score (0.45 adjusted R2). EQ-5D discriminates among CCSG classes (p < 0.000). Physicians detected a 0.16 difference in health state scores. CONCLUSION: The EQ-5D provides valid general HrQOL measurement post-MI.

The case for interdepartmental research in primary care.

Research problems in human biology, clinical medicine, and health services delivery are complex, and increasingly require collaborative approaches. Despite the commitment of general internists, general pediatricians, and family physicians to comprehensive, coordinated, and longitudinal care, their substantial overlap in research topics, methods, and data sources, and their shared emphasis on research conducted in community-based settings, the three primary care disciplines rarely collaborate in research. The research enterprises of most primary care departments and divisions in the United States are small "cottage industries," while interdepartmental research units are rare. Interdepartmental research units can develop and maintain the critical mass of investigators, trainees, and staff that is necessary for an intellectually vibrant and financially sound primary care research enterprise. The University of Colorado Health Sciences Center School of Medicine has developed a successful interdepartmental research effort in primary care that includes joint fellowship training and faculty development programs and a Primary Care Research Unit that supports the analysis of secondary databases, practice-based research networks, and interdisciplinary research projects. Key elements of this collaboration include shared projects among faculty and trainees, proactive negotiation about resources, and shared research space, staff, and faculty. Such a collaboration provides the breadth of perspectives necessary to address complex health care problems, and the pragmatic infrastructure necessary to sustain research themes and careers.

Applied strategies for improving patient safety: a comprehensive process to improve care in rural and frontier communities.

CONTEXT: Medical errors and patient safety have gained increasing attention throughout all areas of medical care. Understanding patient safety in rural settings is crucial for improving care in rural communities. PURPOSE: To describe a system to decrease medical errors and improve care in rural and frontier primary care offices. METHODS: Applied Strategies for Improving Patient Safety (ASIPS) was a demonstration project designed to collect and analyze medical error reports and use these reports to develop and implement interventions aimed at decreasing errors. ASIPS participants were clinicians and staff in 2 practice-based research networks: the Colorado Research Network (CaReNet) and the High Plains Research Network (HPRN). This paper describes ASIPS in HPRN. FINDINGS: Fourteen HPRN practices with a total of 150 clinicians and staff have participated in ASIPS. Participants have submitted 128 reports. Diagnostic tests were involved in 26% of events; medication errors appeared in 20% of events. Communication errors were reported in 72%. Two learning groups developed "Principles for Process Improvement" for medication errors and diagnostic testing errors. Several safety "alerts" were issued to improve care, and 2 interventions were implemented to decrease errors. CONCLUSIONS: A safe and secure reporting system that relies on voluntary reporting from clinicians and staff can be successfully implemented in rural primary care settings. Information from reports can be used to identify processes that can be improved.

Clinical decisions regarding HbA1c results in primary care: a report from CaReNet and HPRN.

OBJECTIVE: To describe decisions made by primary care providers on elevated HbA(1c) results and their reasons for not intensifying therapy. RESEARCH DESIGN AND METHODS: In this cross-sectional study, a provider survey was administered in two practice-based research networks when HbA(1c) results were reviewed on all nonpregnant patients >18 years old with type 2 diabetes. Univariate and Mantel-Hantel analyses assessed associations between patient characteristics and clinical decisions. RESULTS: A total of 483 surveys were completed by at least 88 providers at 19 clinics. Most patients were female (62.5%), mean age was 60 years, and 28.6% were Hispanic. The overall action rate on HbA(1c) results >/=7% (n = 294) was 70.7%. Patients who were black or had Medicare without medication insurance had lower rates of action on HbA(1c) >/=7 and >/=8%, respectively (P < 0.05). The most common reasons providers reported for inaction were "patient improving/doing well," "competing demands," and "hypoglycemic risk." CONCLUSIONS: Primary care providers generally adhere to national glycemic control guidelines, although there may be disparities in black patients and patients without medication insurance coverage. A variety of reasons were given when control was not intensified.

After-hours telephone triage affects patient safety.

OBJECTIVE: To describe the management of after-hours calls to primary care physicians and identify potential errors that might delay evaluation and treatment. STUDY DESIGN: Survey of primary care practices and audit of after-hours phone calls. Ninety-one primary care offices (family medicine, internal medicine, obstetrics, and pediatrics) were surveyed in October and November 2001. Data collected included number of persons answering the calls, information requested, instructions to patients, who decided whether to contact the on-call physician, and subsequent handling of all calls. We evaluated all after-hours calls to an index office that were not forwarded to the on-call physician. Four family physicians independently reviewed the calls while unaware that these calls had not been forwarded to the physician on call to determine the appropriate triage. POPULATION: Primary care physicians and their telephone answering services. OUTCOME MEASURES (1) Who decided to initiate immediate contact with the physician? (2) Percentage of calls identified as emergent or nonemergent by patients. (3) Independent physician ratings of nonemergent calls. RESULTS: More than two thirds of the offices used answering services to take their calls. Ninety-three percent of the practices required the patient to decide whether the problem was emergent enough to require immediate notification of the on-call physician. Physician reviewers reported that 50% (range, 22%-77%) of the calls not forwarded to the on-call physician represented an emergency needing immediate contact with the physician. CONCLUSIONS: After-hours call systems in most primary care offices impose barriers that may delay care. All clinical patient calls should be sent to appropriately trained medical personnel for triage decisions. We urge all clinicians that use an answering service to examine their policies and procedures for possible sources of medical error.

Patient perspectives on the doctor of the future.

BACKGROUND AND OBJECTIVES: Health care reform has been the subject of considerable debate, particularly among those in politics, insurance, and business. Patients, however, have largely been ignored in this discussion. As the role of the health care consumer receives increased attention, it is important to consider patient values and preferences for a future system of care. This study describes what patients want and value in a future doctor METHODS: This study was conducted in 1999-2000, using focus group methodology involving 78 members of communities in seven regions of Colorado. Participants were selected to ensure a distribution of rural/urban, racial/ethnic groups and different regions of the state. All participants had visited a health care provider in the previous 10 years. Data were analyzed with a team-based editing approach. RESULTS: Participants identified several primary domains and subthemes that describe what they want in a doctor of the future. The primary themes related to future doctors' medical and contextual knowledge of the patient, their personal characteristics and philosophical approach to health and health care, and desired qualities of the doctor-patient relationship. CONCLUSIONS: Patients wanted their future doctors to improve their experience of care and to be patient-centered, family-oriented, and community-oriented doctors. Patient perspectives of the doctor of the future should be considered in decisions about health care policy.

Reasons for after-hours calls.

Previous studies of after-hours calls to family physicians focused on caller demographics, medical triage skills, and patient satisfaction, and were usually conducted for a limited time. We examined the frequency and nature of calls to a family practice residency over 1 year. Caller and patient information, date, time, and chief complaint were obtained from answering service logs. The 5 most frequent chief complaints related to medications, pain, obstetric issues, fever, and nausea. Interestingly, 56 "high utilizers" (0.6% of all patients) accounted for 23% of the calls.

Primary care family physicians and 2 hospitalist models: comparison of outcomes, processes, and costs.

OBJECTIVES: To compare the care provided by family practice primary care physicians with that provided by 2 hospitalist models: critical care hospitalists and rotating residency faculty family physician hospitalists. STUDY DESIGN: Retrospective chart review. A health maintenance organization mandated that all patients be admitted to a critical care hospitalist team. The family physician hospitalists admitted all other residency patients and patients of some community family physicians. The primary care physicians admitted all their other patients. We adjusted for disease severity by using the Pneumonia Severity Index, age, sex, and comorbidities. POPULATION: Adults admitted with pneumonia to our private urban community hospital. Exclusions included patients with nosocomial pneumonia, human immunodeficiency virus, and acquired immunodeficiency syndrome. OUTCOMES MEASURED: Primary (adjusted for age, sex, comorbidities, and disease severity): hospital charges, length of stay, in-hospital mortality, readmissions, and returns to the emergency room. Secondary: chest radiographs, intensive care use, blood and sputum cultures, compliance with American Thoracic Society guidelines, lifestyle and end-of-life counseling. RESULTS: Of 97 patients, 21 were admitted to the critical care hospitalists, 53 to the family physician hospitalists, and 23 to primary care physicians. The mean charge ($5680) by the primary care physicians was significantly lower than that of the critical care hospitalists ($10,231; P=.005) and trended toward being lower than that of the family physician hospitalists ($7699; P=.08). The patients of critical care and family physician hospitalists had longer mean lengths of stay (critical care hospitalists, 3.8 days; family physician hospitalists, 3.9 days) than did those of the primary care physicians (2.6 days; P=.04 and.01, respectively). Compared with the primary care physicians, the critical care hospitalists were more likely to obtain at least 2 chest x-rays (odds ratio, 4.1; 95% confidence interval, 1.1-15.5) and trended toward increased odds of lengthy stay in the intensive care unit (odd ratio, 2.9; 95% confidence interval, 0.6-14.6). We found no other significant differences in primary or secondary outcomes. CONCLUSIONS: Claims of better and cheaper care by hospitalists need further investigation. Meanwhile, the use of hospitalists should not be mandated, and the use of family physicians as hospitalists should be considered a good alternative to the use of subspecialists.
