Research recruitment through US central cancer registries: balancing privacy and scientific issues.

Cancer registries are a valuable resource for recruiting participants for public health-oriented research, although such recruitment raises potentially competing concerns about patient privacy and participant accrual. We surveyed US central cancer registries about their policies for research contact with patients, and results showed substantial variation. The strategy used most frequently (37.5% of those that allowed patient contact), which was among the least restrictive, was for investigators to notify patients' physicians and then contact patients with an opt-out approach. The most restrictive strategy was for registry staff to obtain physician permission and contact patients with an opt-in approach. Population-based studies enhance cancer control efforts, and registry policies can affect researchers' ability to conduct such studies. Further discussion about balanced recruitment approaches that protect patient privacy and encourage beneficial research is needed.

The effect of physician permission versus notification on research recruitment through cancer registries (United States).

OBJECTIVE: To determine how physicians responded when investigators inquired about contacting patients identified through a central cancer registry, and to examine participation rates under physician permission versus notification approaches. METHODS: We analyzed existing data from seven observational epidemiologic studies conducted in North Carolina between 1993 and 2004, capitalizing on a 'natural experiment' that arose when the state registry changed from a policy requiring investigators to obtain physician permission to one requiring only physician notification. RESULTS: When a notification approach was used, physicians approved researcher contact with a higher proportion of patients, and a higher proportion of physicians approved contact with or provided eligibility information about all patients requested, compared with a permission approach. Among physicians who were contacted under both approaches, the proportion of patients for whom they approved contact or provided information was significantly higher when they were notified. Physician notification was also associated with higher patient contact and overall response rates. Patient cooperation rates did not differ between the two approaches, suggesting that patients did not respond negatively to the fact that their physician was not explicitly asked to provide permission. CONCLUSION: Notification is likely an efficient way of involving patients' physicians, providing opportunity for physician input but avoiding the burdens associated with requiring their permission.

Simultaneous control of intermediate diabetes outcomes among Veterans Affairs primary care patients.

BACKGROUND: Guidelines recommend tight control of hemoglobin A1c (HbA1c), low-density lipoprotein cholesterol (LDL-C), and blood pressure (BP) for patients with diabetes. The degree to which these intermediate outcomes are simultaneously controlled has not been extensively described. OBJECTIVE: Describe the degree of simultaneous control of HbA1c, LDL-C, and BP among Veterans Affairs (VA) diabetes patients defined by both VA and American Diabetes Association (ADA) guidelines. DESIGN: Cross-sectional cohort. PATIENTS: Eighty-thousand two hundred and seven VA diabetes patients receiving care between October 1999 and September 2000. MEASURMENTS: We defined simultaneous control of outcomes using 1997 VA Guidelines (in place in 2000) (HbA1c < 9.0%; LDL-C < 130 mg/dL; systolic BP < 140 mmHg; and diastolic BP < 90 mmHg) and 2004 ADA guidelines (HbA1c < 7.0%; LDL-C < 100 mg/dL; systolic BP < 130 mmHg; and diastolic BP < 80 mmHg). A patient is considered to have simultaneous control of the intermediate outcomes for a given definition if the average of measurements for each outcome was below the defined threshold during the study period. RESULTS: Using VA guidelines, 31% of patients had simultaneous control. Control levels of individual outcomes were: HbA1c (82%), LDL-C (77%), and BP (48%). Using ADA guidelines, 4% had simultaneous control. Control levels of individual outcomes were: HbA1c (36%), LDL-C (41%), and BP (23%). Associations between individual risk factors were weak. There was a modest association between LDL-C control and control of HbA1c (odds ratio [OR] 1.51; 95% confidence interval [CI] 1.44, 1.58). The association between LDL-C and BP control was clinically small (1.26; 1.21, 1.31), and there was an extremely small association between BP and HbA1c control (0.95; 0.92, 0.99). Logistic regression modeling indicates greater body mass index, African American or Hispanic race-ethnicity, and female gender were negatively associated with simultaneous control. CONCLUSION: While the proportion of patients who achieved minimal levels of control of HbA1c and LDL-C was high, these data indicate a low level of simultaneous control of HbA1c, LDL-C, and BP among patients with diabetes.

Patient perspectives on research recruitment through cancer registries.

OBJECTIVE: To gain preliminary insight into patients' levels of awareness and preferences about research recruitment through cancer registries. METHODS: We developed four questions about the North Carolina Central Cancer Registry's educational brochure and about patient preferences regarding physician involvement in research recruitment. These questions were included in the baseline interview conducted among 100 consecutively enrolled participants in the North Carolina Colorectal Cancer Care Outcomes Research Study, an ongoing observational study. RESULTS: Patients who read the Registry's educational brochure generally reported that it helped them understand that a researcher could contact them, but only about one-fourth of patients recalled receiving and reading the brochure. Over two-thirds of patients said they preferred that researchers contact them directly about their interest in research participation, rather than checking with their physician first. Among patients who wanted their physician involved, most preferred a physician notification rather than a physician permission approach. CONCLUSIONS: Registry policies about patient education and physician involvement can have an important impact on researchers' ability to conduct population-based studies. Understanding patient perspectives is key to developing balanced policies that protect patients' privacy, as well as facilitate their opportunities to make autonomous decisions about participating in research.

A randomized trial of a primary care-based disease management program to improve cardiovascular risk factors and glycated hemoglobin levels in patients with diabetes.

PURPOSE: To assess the efficacy of a pharmacist-led, primary care-based, disease management program to improve cardiovascular risk factors and glycated hemoglobin (A(1C)) levels in vulnerable patients with poorly controlled diabetes. METHODS: A randomized controlled trial of 217 patients with type 2 diabetes and poor glycemic control (A(1C) level >or=8.0%) was conducted at an academic general medicine practice from February 2001 to April 2003. Intervention patients received intensive management from clinical pharmacists, as well as from a diabetes care coordinator who provided diabetes education, applied algorithms for managing glucose control and decreasing cardiovascular risk factors, and addressed barriers to care. Control patients received a one-time management session from a pharmacist followed by usual care from their primary care provider. Outcomes were recorded at baseline and at 6 and 12 months. Primary outcomes included blood pressure, A(1C) level, cholesterol level, and aspirin use. Secondary outcomes included diabetes knowledge, satisfaction, use of clinical services, and adverse events. RESULTS: For the 194 patients (89%) with 12-month data, the intervention group had significantly greater improvement than did the control group for systolic blood pressure (-9 mm Hg; 95% confidence interval [CI]: -16 to -3 mm Hg) and A(1C) level (-0.8%; 95% CI: -1.7% to 0%). Change in total cholesterol level was not significant. At 12 months, aspirin use was 91% in the intervention group versus 58% among controls (P <0.0001). Intervention patients had greater improvements in diabetes knowledge and satisfaction than did control patients. There were no significant differences in use of clinical services or adverse events. CONCLUSION: Our comprehensive disease management program reduced cardiovascular risk factors and A(1C) levels among vulnerable patients with type 2 diabetes and poor glycemic control.

Patient satisfaction and use of Veterans Affairs versus non-Veterans Affairs healthcare services by veterans.

OBJECTIVES: Chronically ill patients who are not satisfied with their care may change healthcare providers or systems, which could disrupt continuity of care and impede management of their conditions. We examined whether patient satisfaction affected subsequent use of non-Veterans Affairs (VA) services among chronically ill veterans discharged from VA hospitals. METHODS: The data used in this study came from a multicenter trial of increased access to primary care. We enrolled patients with diabetes, heart failure, and/or chronic obstructive pulmonary disease who were discharged from 1 of 9 VA medical centers. At baseline, we assessed satisfaction using the Patient Satisfaction Questionnaire. VA and non-VA utilization over the subsequent 6 months were assessed using VA and Medicare administrative data, non-VA billing data, and patient interviews. Using multivariable logistic regression analyses, we examined whether baseline patient satisfaction was associated with non-VA inpatient or outpatient utilization during the next 6 months. We conducted the same analysis for Medicare-eligible veterans, a group with better access to non-VA care. RESULTS: Of 1375 study patients, 174 (13%) used non-VA healthcare. Patients with non-VA utilization were older and lived farther from a VA. The odds of non-VA use decreased by 11% as satisfaction increased (odds ratio 0.89; 95% confidence interval 0.83-0.97; P = 0.005). This relationship was strongest among Medicare-eligible veterans (odds ratio 0.85; 95% confidence interval 0.77-0.93; P = 0.001). CONCLUSIONS: Dissatisfied veterans discharged from the hospital were more likely to go outside VA for care. Thus, improvements in patient satisfaction may lead to improvements in continuity of care.

Can shelter-based interventions improve treatment engagement in homeless individuals with psychiatric and/or substance misuse disorders?: a randomized controlled trial.

BACKGROUND: High proportions of homeless individuals have mental illness and substance use disorders. Few of these individuals engage in consistent treatment, although they are likely to benefit from it. Shelter-based interventions to help this population engage in treatment have not been studied in a rigorous manner. OBJECTIVES: We sought to evaluate the effectiveness of a shelter-based intervention, including intensive outreach by a psychiatric social worker and availability of weekly psychiatrist visits with continuity of care to engage homeless individuals with psychiatric and substance use problems. RESEARCH DESIGN: This was a randomized controlled trial. SUBJECTS: A total of 102 individuals were referred to a shelter-based psychiatric clinic. MEASURES: The primary outcome measure was first appointment attendance at a community mental health center (CMHC). Secondary outcome measures were attendance at second and third CMHC appointments, participation in a substance abuse program, and employment and housing status at shelter exit. RESULTS: Individuals receiving the intervention were more likely to attend > or =1 CMHC appointment (64.7% versus 37.3%, P = 0.006) and to participate in a substance abuse program (51.4% versus 12.5%, P = 0.0006) than those in the control group. There was a trend towards being more likely to attend 2 CMHC visits (33.3% versus 17.7%, P = 0.083), but no significant differences in attending 3 visits, being employed, or having housing. CONCLUSIONS: Shelter-based interventions hold promise for improving treatment engagement in homeless populations with psychiatric and substance use problems. Further study should address how to foster care beyond an initial CMHC appointment and clarify key program components using a wider range of outcome measures.

Race, ethnicity, socioeconomic position, and quality of care for adults with diabetes enrolled in managed care: the Translating Research Into Action for Diabetes (TRIAD) study.

OBJECTIVE: To examine racial/ethnic and socioeconomic variation in diabetes care in managed-care settings. RESEARCH DESIGN AND METHODS: We studied 7,456 adults enrolled in health plans participating in the Translating Research Into Action for Diabetes study, a six-center cohort study of diabetes in managed care. Cross-sectional analyses using hierarchical regression models assessed processes of care (HbA(1c) [A1C], lipid, and proteinuria assessment; foot and dilated eye examinations; use or advice to use aspirin; and influenza vaccination) and intermediate health outcomes (A1C, LDL, and blood pressure control). RESULTS: Most quality indicators and intermediate outcomes were comparable across race/ethnicity and socioeconomic position (SEP). Latinos and Asians/Pacific Islanders had similar or better processes and intermediate outcomes than whites with the exception of slightly higher A1C levels. Compared with whites, African Americans had lower rates of A1C and LDL measurement and influenza vaccination, higher rates of foot and dilated eye examinations, and the poorest blood pressure and lipid control. The main SEP difference was lower rates of dilated eye examinations among poorer and less educated individuals. In almost all instances, racial/ethnic minorities or low SEP participants with poor glycemic, blood pressure, and lipid control received similar or more appropriate intensification of therapy relative to whites or those with higher SEP. CONCLUSIONS: In these managed-care settings, minority race/ethnicity was not consistently associated with worse processes or outcomes, and not all differences favored whites. The only notable SEP disparity was in rates of dilated eye examinations. Social disparities in health may be reduced in managed-care settings.

Veterans Affairs primary care organizational characteristics associated with better diabetes control.

OBJECTIVE: To examine organizational features of Veterans Affairs (VA) primary care programs hypothesized to be associated with better diabetes control, as indicated by hemoglobin A1C (HbA1C) levels. STUDY DESIGN: Cross-sectional cohort. METHODS: We established a cohort of 224 221 diabetic patients using the VA Diabetes Registry and Dataset and VA corporate databases. The 1999 VHA (Veterans Health Administration) Survey of Primary Care Practices results were combined with individual patient data. A 2-level hierarchical model was used to determine the relationship between organizational characteristics and HbA1C levels in 177 clinics with 82 428 cohort members. RESULTS: The following attributes were associated with lower (better) HbA1C and were statistically significant at P < .05: greater authority to establish or implement clinical policies (lower by 0.21%), greater staffing authority (0.28%), computerized diabetes reminders (0.17%), notifying all patients of their assigned provider (0.21%), hiring needed new staff during fiscal year 1999 (0.18%), having nurses that report only to the program (0.16%), and being a large academic practice (0.27%). Associated with higher (worse) HbA1C were programs reporting that patients almost always see their assigned provider (greater by 0.18%), having a quality improvement program involving all nurses without all physicians (0.38%), having general internal medicine physicians report only to the program (0.20%), and being located at an acute care hospital (0.20%). CONCLUSION: Programs that are associated with better diabetes control simultaneously have teams that actively involve physicians in quality improvement, use electronic health information systems, have authority to respond to staffing and programmatic issues, and engage patients in care.

The influence of physicians' guideline compliance on patients' statin adherence: a retrospective cohort study.

BACKGROUND: National cholesterol management guidelines recommend regular follow-up of patients and annual lipid evaluations to promote adherence to statin therapy. OBJECTIVE: This study examined the relationship between primary care physicians' (PCPs') compliance with primary care guidelines and patients' adherence to statin therapy. METHODS: A retrospective cohort study was conducted among statin users aged > or = 50 years who had an assigned PCP at a Veterans Affairs Medical Center. The dependent variable was statin adherence by patients over 24 months. Computerized pharmacy, laboratory, and medical records were used to measure PCPs' compliance with 4 recommendations in national cholesterol management guidelines: (1) lipid-lowering drug (LLD) initiation; (2) 8-week follow-up visit after an initial LLD prescription; (3) 6- or 12-month follow-up visit for established LLD users; and (4) annual lipid evaluation. Multilevel, multivariable regression models were used to estimate the effects of PCPs' guideline compliance on patients' adherence while controlling for patients' demographic characteristics, comorbid conditions, and pharmacotherapy factors. RESULTS: The sample included 82 PCPs caring for 4707 patients. The mean statin adherence rate was 83.9%. An increase in the annual lipid evaluation rate resulted in an increase in patients' adherence (P = 0.037). Black race and higher statin dose negatively influenced patients' adherence (both, P < 0.001). The effects of PCPs' compliance rates were not homogeneous across race. Specifically, the 8-week follow-up visit rate after initial LLD prescription was significantly associated with improved statin adherence among the black subpopulation only. CONCLUSIONS: Patients' adherence to statin therapy was influenced by their PCPs' compliance with cholesterol management guidelines. Efforts should be made to align PCPs' practice with published guidelines for optimal statin therapy, especially for vulnerable subpopulations of patients.

Influence of patient literacy on the effectiveness of a primary care-based diabetes disease management program.

CONTEXT: Low literacy is an important barrier for patients with diabetes, but interventions to address low literacy have not been well examined. OBJECTIVE: To examine the role of literacy on the effectiveness of a comprehensive disease management program for patients with diabetes. DESIGN, SETTING, AND PARTICIPANTS: Analysis of the influence of literacy on glycemic control and systolic blood pressure using data from a randomized controlled trial (conducted from February 2001 through April 2003) of a comprehensive diabetes management program. Participants were 217 patients aged 18 years or older with type 2 diabetes and poor glycemic control (glycosylated hemoglobin [HbA1c] levels > or =8.0%) and presenting to a US academic general internal medicine practice. INTERVENTIONS: All communication to patients was individualized and delivered to enhance comprehension among patients with low literacy. Intervention patients received intensive disease management from a multidisciplinary team. Control patients received an initial management session and continued with usual care. MAIN OUTCOME MEASURES: Achievement of goal HbA1c levels and systolic blood pressure at 12-month follow-up for control and intervention patients stratified by literacy status. RESULTS: Complete 12-month data were available for 193 patients (89%). Among patients with low literacy, intervention patients were more likely than control patients to achieve goal HbA1c levels (< or =7.0%) (42% vs 15%, respectively; adjusted odds ratio [OR], 4.6; 95% confidence interval [CI], 1.3 to 17.2; P = .02). Patients with higher literacy had similar odds of achieving goal HbA1c levels regardless of intervention status (24% vs 23%; adjusted OR, 1.0; 95% CI, 0.4 to 2.5; P = .98). Improvements in systolic blood pressure were similar by literacy status. CONCLUSIONS: Literacy may be an important factor for predicting who will benefit from an intervention for diabetes management. A diabetes disease management program that addresses literacy may be particularly beneficial for patients with low literacy, and increasing access to such a program could help reduce health disparities.

Predicting reports of unmet expectations among rheumatology patients.

OBJECTIVE: Approximately 25% of patients report unmet expectations after their doctor visits. In a longitudinal study of rheumatology patients, we examined whether changes in health status could predict unmet expectations. METHODS: Arthritis patients (n = 177) responded to 2 surveys (baseline and 6-month followup). Both surveys contained questions on health status (functional status, pain, helplessness, psychological status) and visit duration. The followup survey contained questions on postvisit unmet expectations. Factors associated with unmet expectations were determined. RESULTS: Fifty-eight patients (33%) reported unmet expectations, most often for information (47%) and new medications (31%). Unmet expectations were more common among patients with greater baseline helplessness (odds ratio [OR] 1.9, 95% confidence interval [95% CI] 1.0-3.6) and short doctor visits at followup (OR 5.6, 95% CI 2.4-13.1). Unmet expectations were less common among those experiencing a decline in pain (OR 0.3, 95% CI 0.1-0.9). CONCLUSION: Attention to the patient's level of pain and helplessness and duration of the visit may limit reports of unmet expectations.

Effects of geriatric evaluation and management on adverse drug reactions and suboptimal prescribing in the frail elderly.

PURPOSE: To determine if inpatient or outpatient geriatric evaluation and management, as compared with usual care, reduces adverse drug reactions and suboptimal prescribing in frail elderly patients. METHODS: The study employed a randomized 2 x 2 factorial controlled design. Subjects were patients in 11 Veterans Affairs (VA) hospitals who were > or =65 years old and met criteria for frailty (n = 834). Inpatient geriatric unit and outpatient geriatric clinic teams evaluated and managed patients according to published guidelines and VA standards. Patients were followed for 12 months. Blinded physician-pharmacist pairs rated adverse drug reactions for causality (using Naranjo's algorithm) and seriousness. Suboptimal prescribing measures included unnecessary and inappropriate drug use (Medication Appropriateness Index), inappropriate drug use (Beers criteria), and underuse. RESULTS: For serious adverse drug reactions, there were no inpatient geriatric unit effects during the inpatient or outpatient follow-up periods. Outpatient geriatric clinic care resulted in a 35% reduction in the risk of a serious adverse drug reaction compared with usual care (adjusted relative risk = 0.65; 95% confidence interval: 0.45 to 0.93). Inpatient geriatric unit care reduced unnecessary and inappropriate drug use and underuse significantly during the inpatient period (P <0.05). Outpatient geriatric clinic care reduced the number of conditions with omitted drugs significantly during the outpatient period (P <0.05). CONCLUSION: Compared with usual care, outpatient geriatric evaluation and management reduces serious adverse drug reactions, and inpatient and outpatient geriatric evaluation and management reduces suboptimal prescribing, in frail elderly patients.

A controlled trial of including symptom data in computer-based care suggestions for managing patients with chronic heart failure.

BACKGROUND: Heart failure is common and associated with considerable morbidity and cost, yet physician adherence to treatment guidelines is suboptimal. We conducted a randomized controlled study to determine if adding symptom information to evidence-based, computer-generated care suggestions would affect treatment decisions among primary care physicians caring for outpatients with heart failure at two Veterans Affairs medical centers. METHODS: Physicians were randomly assigned to receive either care suggestions generated with electronic medical record data and symptom data obtained from questionnaires mailed to patients within 2 weeks of scheduled outpatient visits (intervention group) or suggestions generated with electronic medical record data alone (control group). Patients had to have a diagnosis of heart failure and objective evidence of left ventricular systolic dysfunction. We assessed physician adherence to heart failure guidelines, as well as patients' New York Heart Association (NYHA) class, quality of life, satisfaction with care, hospitalizations, and outpatient visits, at 6 and 12 months after enrollment. RESULTS: Patients in the intervention (n = 355) and control (n = 365) groups were similar at baseline. At 12 months, there were no significant differences in adherence to care suggestions between physicians in the intervention and control groups (33% vs. 30%, P = 0.4). There were also no significant changes in NYHA class (P = 0.1) and quality-of-life measures (P >0.1), as well as no differences in the number of outpatient visits between intervention and control patients (6.7 vs. 7.1 visits, P = 0.48). Intervention patients were more satisfied with their physicians (P = 0.02) and primary care visit (P = 0.02), but had more all-cause hospitalizations at 6 months (1.5 vs. 0.7 hospitalizations, P = 0.0002) and 12 months (2.3 vs. 1.7 hospitalizations, P = 0.05). CONCLUSION: Adding symptom information to computer-generated care suggestions for patients with heart failure did not affect physician treatment decisions or improve patient outcomes.

A conceptual framework to study medication adherence in older adults.

BACKGROUND: Adults aged > or =50 years often have multiple chronic diseases requiring multiple medications. However, even drugs with well-documented benefits are often not taken as prescribed, for a variety of reasons. OBJECTIVE: The objective of this article was to provide background information about medication adherence and its measurement, the development of the conceptual model for use in adherence research, and supportive intervention strategies such as pharmaceutical care by pharmacists to improve chronic medication use in older adults. METHODS: English-language literature published from 1990 to 2000 was searched on MEDLINE, International Pharmaceutical Abstracts, and AARP Ageline using the terms aged, heart failure, CHF, adherence, chronic heart failure, compliance, and related terms. The authors used their personal files and libraries to obtain seminal literature and textbooks published before 1990. RESULTS: Although the cognitive processes needed to manage and take medications decline with aging, the number of prescription and nonprescription medications consumed increases. Other factors such as vision, hearing, health literacy, disability, and social and financial resources may all complicate the ability of older adults to adhere to the pharmacologic prescription. CONCLUSIONS: Many factors are associated with medication adherence and related health outcomes in older adults. Therefore, strategies to improve adherence will need to be multidimensional, including improvements in pharmacy services that consider age-related factors (eg, declining cognitive and physical functions) as well as a variety of environmental and social factors.

Methodology of an ongoing, randomized, controlled trial to improve drug use for elderly patients with chronic heart failure.

BACKGROUND: Medications can improve the functioning and health-related quality of life of patients with chronic heart failure (CHF) and reduce morbidity, mortality, and costs of treatment. However, patients may not adhere to therapy. Patients with complex medication regimens and low health literacy are at risk for nonadherence. OBJECTIVE: The primary goal of this project is to develop and assess a multilevel pharmacy-based program to improve patient medication adherence and health outcomes for elderly CHF patients with low health literacy. METHODS: In this 4-year, controlled trial, patients aged 50 years with a diagnosis of CHF who are being treated at Wishard Health Services (Indianapolis, Indiana) are randomly assigned to pharmacist intervention or usual care. Intervention patients receive 9 months of pharmacist support and 3 months of postintervention follow-up. The intervention involves a pharmacist providing verbal and written education, icon-based labeling of medication containers, and therapeutic monitoring. The pharmacist identifies patients' barriers to appropriate drug use, coaches them on overcoming these barriers, and coordinates medication use issues with their primary care providers. Daily updates of relevant monitoring data are delivered via an electronic medical record system and stored in a personal computer system designed to support pharmacist monitoring and facilitate documentation of interventions. To measure medication adherence objectively, electronic monitoring lids are used on all CHF medications for patients in both study groups. Other assessments include self-reported medication adherence, results of echocardiography (eg, ejection fraction), brain natriuretic peptide concentrations, and health-related quality of life. Health services utilization, refill adherence, and cost data derive from electronic medical records. After completion of this study, the data can be used to assess the effectiveness and cost-effectiveness of our intervention. RESULTS: One hundred twenty-two patients have been assigned to receive the intervention and 192 to receive usual care. CONCLUSIONS: Our study aims to improve patients' knowledge and self-management of their medication and to improve medication monitoring in a multilevel pharmacy-based intervention. By doing so, we intend that the intervention will improve the health outcomes of elderly patients with CHF.
