Substantial changes in not only access to care, cost, and quality of care, but also health professions education are needed to ensure effective national healthcare reform. Since the actionable ...determinants of health such as personal beliefs and behaviors, socioeconomic factors, and the environment disproportionately affect the poor (and often racial/ethnic minorities), many have suggested that focusing efforts on this population will both directly and indirectly improve the overall health of the nation. Key to the success of such strategies are the ongoing efforts by historically black medical schools (HBMSs) as well as other minority serving medical and health professional schools, who produce a disproportionate percentage of the high-quality and diverse health professionals that are dedicated to maintaining the health of an increasingly diverse nation. Despite their public mission, HBMSs receive limited public support threatening their ability to not only meet the increasing minority health workforce needs but to even sustain their existing contributions. Substantial changes in health education policy and funding are needed to ensure HBMSs as well as other minority-serving medical and health professional schools can continue to produce the diverse, high-quality health professional workforce necessary to maintain the health of an increasingly diverse nation. We explore several model initiatives including focused partnerships with legislative and business leaders that are urgently needed to ensure the ability of HBMSs to maintain their legacy of providing compassionate, quality care to the communities in greatest need.
Background The National Kidney Foundation Kidney Early Evaluation Program (KEEP) is a free community-based health-screening program targeting populations at greatest risk of chronic kidney disease ...(CKD), those with high rates of diabetes and hypertension, and a high proportion of racial/ethnic minorities. The KEEP Longitudinal Survey will adopt methods similar to those used in KEEP to gather follow-up data to measure CKD-related heath status and gauge program effectiveness for repeated KEEP participants with evidence of CKD stages 3 to 5. KEEP has defined objectives to enhance follow-up survey response rates and target vulnerable populations who bear the greatest CKD risk-factor burdens. Methods The KEEP Follow-up Form was assessed for adherence to 6 cognitive design principles (simplicity, consistency, organization, natural order, clarity, and attractiveness) considered to summate the techniques guiding good survey development and for the additional cognitive design principles of readability and variation of readability across survey items. Results The KEEP Follow-up Form was found to include violations of each cognitive design principle and readability principle, possibly contributing to item nonresponse and low follow-up rates in KEEP. It was revised according to empirically substantiated formatting techniques guided by these principles and found during qualitative assessment to be more user friendly, simpler, better organized, more attractive, and easier to read. Subsequent development of the KEEP Longitudinal Survey form also was guided by these principles. Conclusion To ensure ease of use by populations with limited literacy skills, poor health literacy, and limited survey literacy, survey researchers must apply cognitive design principles to survey development to improve participation and response rates.
Background Albuminuria is an important marker for chronic kidney disease and progression to end-stage renal disease in the general population; understanding racial and ethnic differences can help ...inform efforts to reduce health disparities. We sought to estimate independent associations of race/ethnicity with albuminuria to determine whether observed differences were attributable to known kidney disease risk factors. Methods This cross-sectional study included 64,161 Kidney Early Evaluation Program (KEEP) participants, 2000-2008, with estimated glomerular filtration rate ≥ 60 mL/min/1.73 m2 , not on regular dialysis therapy, and without a previous kidney transplant. Albuminuria (urine albumin-creatinine ratio ≥ 30 mg/g) was examined by self-reported race and ethnicity. Covariates were age, sex, educational level, body mass index, diabetes status or glucose level, hypertension status or blood pressure measurement, smoking status, health insurance status, and geographic region. Results Albuminuria prevalences were 8% (n = 2,303) in whites, 11% (n = 2,310) in African Americans, 9% (n = 730) in Hispanics, 10% (n = 381) in Asians, and 15% (n = 344) in American Indians/Alaska Natives. Compared with whites, odds of albuminuria were higher for all groups after multivariate adjustment. Odds were highest for American Indians/Alaska Natives (adjusted OR, 1.93; 95% CI, 1.70-2.20), then Asians (adjusted OR, 1.42; 95% CI, 1.26-1.61), African Americans (adjusted OR, 1.38; 95% CI, 1.29-1.47), and Hispanics (adjusted OR, 1.19; 95% CI, 1.08-1.31). Conclusions In the KEEP study population, albuminuria prevalence was higher in African Americans, Hispanics, Asians, and American Indians/Alaska Natives than in non-Hispanic whites, suggesting a need for screening for early detection of kidney damage, especially in people at increased risk, in the community primary care setting.
This report retrospectively examines the structure of an emerging community-academic participatory research (PR) partnership that was not sustainable, despite attempts to adhere to PR principles and ...demonstrable success in research outcomes. The influence of community and academic parent organizations on the PR process and outcomes is presented in the context of the Donabedian Model. We dissected the structural elements contributed by parent organizations to forming the structure of the PR partnership (memorandum of understanding, policy environment, human resources and effort, community and academic resources, expertise and experience, and funding) and explored the influence of potential and actual conflicts on the PR partnership’s sustainability. The effect of potential and actual conflict on the PR process and quality of PR outcomes is discussed. Based on this, we conclude by proposing seven core standards for the establishment and development of emerging community-academic PR partnerships.
Background Elderly individuals with chronic kidney disease (CKD) have high rates of comorbid conditions, including cardiovascular disease and its risk factors, and CKD-related complications. In ...individuals aged ≥ 65 years, we sought to describe the prevalence of CKD determined from laboratory test results in the Kidney Early Evaluation Program (KEEP; n = 27,017) and National Health and Nutrition Examination Survey (NHANES) 1999-2006 (n = 5,538) and the prevalence of diagnosed CKD determined from billing codes in the Medicare 5% sample (n = 1,236,946). In all 3 data sources, we also explored comorbid conditions and CKD-related complications. Methods CKD was identified as decreased estimated glomerular filtration rate (<60 mL/min/1.73 m2 ) or increased albumin-creatinine ratio in KEEP and NHANES; CKD was identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes in Medicare. Investigated comorbid conditions included diabetes, hypertension, high cholesterol level, coronary artery disease, congestive heart failure, cerebrovascular disease, peripheral vascular disease, and cancer, and CKD-related complications included anemia, hypocalcemia, hyperphosphatemia, and hyperparathyroidism. Results The prevalence of CKD was ∼44% in both KEEP and NHANES participants, and the prevalence of diagnosed CKD was 7% in Medicare beneficiaries. In all 3 data sets, the prevalence of CKD or diagnosed CKD was higher in participants aged ≥ 80 years and those with comorbid conditions. For KEEP and NHANES participants, the prevalence of most comorbid conditions and CKD complications increased with decreasing estimated glomerular filtration rate. For participants with CKD stages 3-5, a total of 29.2% (95% CI, 27.8-30.6) in KEEP and 19.9% (95% CI, 17.0-23.1) in NHANES had anemia, 0.7% (95% CI, 0.4-0.9) and 0.6% (95% CI, 0.3-1.3) had hypocalcemia, 5.4% (95% CI, 4.7-6.1) and 6.4% (95% CI, 5.1-8.0) had hyperphosphatemia, and 52.0% (95% CI, 50.4-53.6) and 30.0% (95% CI, 25.9-34.3) had hyperparathyroidism, respectively. Conclusions CKD is common in the elderly population and is associated with high frequencies of concomitant comorbid conditions and biochemical abnormalities. Because CKD is not commonly diagnosed, greater emphasis on physician education may be beneficial.
Background Chronic kidney disease (CKD) is recognized as an independent cardiovascular disease (CVD) risk state, particularly in the elderly, and has been defined by levels of estimated glomerular ...filtration rate (eGFR) and markers of kidney damage. The relationship between CKD and CVD in younger and middle-aged adults has not been fully explored. Methods Community volunteers completed surveys regarding past medical events and underwent blood pressure and laboratory testing. Chronic kidney disease was defined as an eGFR <60 mL·min−1 ·1.73 m−2 or urine albumin-creatinine ratio (ACR) ≥30 mg/g. Premature CVD was defined as self-reported myocardial infarction or stroke at <55 years of age in men and <65 years of age in women. Mortality was ascertained by linkage to national data systems. Results Of 31 417 participants, the mean age was 45.1 ± 11.2 years, 75.5% were female, 36.8% African American, and 21.6% had diabetes. A total of 20.6% were found to have CKD, with the ACR and eGFR being the dominant positive screening tests in the younger and older age deciles, respectively. The prevalences of premature myocardial infarction (MI), stroke, or death, and the composite were 5.3%, 4.7%, 0.8%, 9.2%, and 2.5%, 2.2%, 0.2%, 4.2% for those with and without CKD, respectively ( P < .0001 for composite). Multivariable analysis found CKD (OR 1.44, 95% CI 1.27-1.63), age (OR 1.05 per year, 95% CI 1.04-1.06), hypertension (OR 1.61, 95% CI 1.40-1.84), diabetes (OR 2.03, 95% CI 1.79-2.29), smoking (OR 1.91, 95% CI 1.66–2.21), and less than high school education (OR 1.59, 95% CI 1.37-1.85) as the most significantly associated factors for premature CVD or death (all P < .0001). Survival analysis found those with premature MI or stroke and CKD had the poorest short-term survival over the next 3 years after screening. Conclusions Chronic kidney disease is an independent predictor of MI, stroke, and death among men and women younger than age 55 and 65 years, respectively. These data suggest the biologic changes that occur with kidney failure promote CVD at an accelerated rate that cannot be fully explained by conventional risk factors or older age. Screening for CKD by using both the ACR and eGFR can identify younger and middle-aged individuals at high risk for premature CVD and near-term death.
Background Chronic kidney disease (CKD) is recognized as an independent cardiovascular disease risk state. The relationship between CKD and cardiovascular disease in volunteer and general populations ...has not been explored. Methods The National Kidney Foundation Kidney Early Evaluation Program (KEEP) is a community-based health-screening program to raise kidney disease awareness and detect CKD for early disease intervention in individuals 18 years or older with diabetes, hypertension, or family history of kidney disease, diabetes, or hypertension. KEEP volunteers completed surveys and underwent blood pressure and laboratory testing. Estimated glomerular filtration rate (eGFR) was computed, and urine albumin-creatinine ratio (ACR) was measured. In KEEP, CKD was defined as eGFR less than 60 mL/min/1.73 m2 or ACR of 30 mg/g or greater. Cardiovascular disease was defined as self-reported myocardial infarction or stroke. Data were compared with National Health and Nutrition Examination Survey (NHANES) 1999-2004 data for prevalence of cardiovascular disease risk factors and cardiovascular outcomes. Results Of 69,244 KEEP participants, mean age was 53.4 ± 15.7 years, 68.3% were women, 33.0% were African American, and 27.6% had diabetes. Of 17,061 NHANES participants, mean age was 45.1 ± 0.27 years, 52% were women, 11.2% were African American, and 6.7% had diabetes. In KEEP, 26.8% had CKD, and in NHANES, 15.3%. ACR was the dominant positive screening test for younger age groups, and eGFR, for older age groups, for both populations. Prevalences of myocardial infarction or stroke were 16.5% in KEEP and 15.1% in NHANES ( P < 0.001) and 7.8% in KEEP and 3.7% in NHANES ( P < 0.001) for individuals with and without CKD, respectively. In adjusted analysis of both KEEP and NHANES data, CKD was associated with a significantly increased risk of prevalent myocardial infarction or stroke (odds ratio, 1.34; 95% confidence interval, 1.25 to 1.43; odds ratio, 1.37; 95% confidence interval, 1.10 to 1.70, respectively). In KEEP, short-term mortality was greater in individuals with CKD (1.52 versus 0.33 events/1,000 patient-years). Conclusions CKD is independently associated with myocardial infarction or stroke in participants in a voluntary screening program and a randomly selected survey population. Heightened concerns regarding risks in volunteers yielded greater cardiovascular disease prevalence in KEEP, which was associated with increased short-term mortality.
Chronic kidney disease is a non-communicable disease that is now well recognized as a major source of premature morbidity and mortality. In general, racial/ethnic minorities in the United States are ...more likely than non-minority groups to develop end-stage renal disease (ESRD), but paradoxically most have a lower mortality risk. Unlike most minorities, dialysis patients in Puerto Rico have a mortality risk nearly 50% higher than the national average. Multiple factors such as medical conditions, socioeconomic, environmental, and health system factors can influence health outcomes for patients with ESRD. We describe one potential health system factor that may contribute to this finding, a unique interpretation and implementation of the ESRD Medicare Secondary Payer provision in the Commonwealth of Puerto Rico. We conducted a search of regulatory documents and key stakeholder interviews to help envision the potential implications of these differences for dialysis facilities, health care providers, and patients with ESRD.
A high level of minimal residual disease (MRD) after induction chemotherapy in children with acute lymphoblastic leukemia (ALL) is an indicator of relative chemotherapy resistance and a risk factor ...for relapse. However, the significance of MRD in the second year of therapy is unclear. Moreover, it is unknown whether treatment intervention can alter outcome in patients with detectable MRD.
We assessed the prognostic value of MRD testing in bone marrow samples from 85 children at 1, 12, and 24 months from diagnosis using clone-specific polymerase chain reaction primers designed to detect clonal antigen receptor gene rearrangements. These children were part of a multicenter, randomized clinical trial, which, in the second year of treatment, compared a 2-month reinduction-reintensification followed by maintenance chemotherapy with standard maintenance chemotherapy alone.
MRD was detected in 69% of patients at 1 month, 25% at 12 months, and 28% at 24 months from diagnosis. By univariate analysis, high levels of MRD at 1 month, or the presence of any detectable MRD at 12 or 24 months from diagnosis, were highly predictive of relapse. Multivariate analysis showed that MRD testing at 1 and 24 months each had independent prognostic significance. Intensified therapy at 12 months from diagnosis did not improve prognosis in those patients who were MRD positive at 12 months from diagnosis.
Clinical outcome in childhood ALL can be predicted with high accuracy by combining the results of MRD testing at 1 and 24 months from diagnosis.
