Considering the role of nephrologists as primary care providers for their chronic dialysis patients requires exploration of a number of factors. These factors include the definition of a primary care provider, the time and expertise needed to provide primary care, the expectations of nephrologists and dialysis patients who give and receive primary care, the appropriate preventive care for end-stage renal disease (ESRD) patients, and the current and future roles of nephrologists within a changing health care environment. Unfortunately, few studies have addressed these issues, and there is little objective information on which to base guidelines and recommendations about nephrologist-directed primary care of ESRD patients. Most nephrologists spend a significant portion (30% to 35%) of their time caring for dialysis patients, and 90% report providing primary care to dialysis patients. Most dialysis patients view their nephrologist as their primary care provider. The increasingly aged and ill ESRD population will undoubtedly necessitate additional time and expertise for care from an understaffed nephrology work force. The increased use of advanced practice nurses and alliances with health care delivery systems under global capitation programs may develop into effective strategies to provide care for an increasing population of dialysis patients. The nonnephrologic health care needs, including specific and appropriate cancer screening and preventive health care protocols for ESRD patients whose life expectancies are significantly less than the general population, are unclear. The issues involved in considering nephrologists as primary caregivers for ESRD patients include these and other related factors, and will be discussed in this review. 相似文献

Many older patients with advanced CKD approaching ESRD do not receive timely nephrology care, although data suggest that the situation may be improving. In 2005–2008, 43% of older patients who initiated renal replacement therapy had experienced an outpatient nephrologist consultation more than 1 year before starting treatment. Earlier consultation with a nephrologist has been found to provide better access to peritoneal dialysis and kidney transplantation, better preparation for the chosen dialytic modality, and improved survival after start of dialysis or receipt of a kidney transplant. Recent data suggest that older individuals are less likely to receive treatment for ESRD compared with younger individuals in whom almost all receive dialysis treatment or transplantation. Little is known about the role nephrologists play in the decision whether to initiate dialysis or choose a conservative route among older adults with ESRD. Defining the appropriate role and involvement of nephrologists in the decision about initiating renal replacement therapy in older adults seems ripe for further investigation and discussion. 相似文献

Vascular access has been a major problem in the management of end stage renal disease (ESRD) patients on chronic hemodialysis (HD). Native arteriovenous fistulas (AVFs) are the preferred vascular access for ESRD patients on HD. Multiple factors have been evaluated as causes for poor AVF rates. The purpose of this retrospective analysis was to assess the impact of training of nephrologist in interventional nephrology (IN) on vascular access outcomes. We studied the rates of different types of vascular access amongst patients on chronic HD under the care of two nephrology groups over 25 months in a community dialysis unit. In group A, all vascular access were managed directly by an interventional nephrologist, while in group B they were managed by general nephrologist with no exposure to IN during their training. A total of 129 patients received dialysis for at least 4 months at the unit during those 25 months. The rate of AVFs in group A was 56.6%, while in group B the rate of AVFs was 40.8% ( p = 0.059). The rate of AVGs in group A was 22.9% and in group B it was 27.6% ( p = 0.647). The tunneled HD catheter rate in group A was 20.4% and in group B it was 31.6% ( p = 0.098). The results of this study demonstrate that training of nephrologists in IN leads to increased use of AVF as HD vascular access. We suggest that training programs in nephrology should consider incorporating IN into their programs to increase the prevalence of AVFs. 相似文献

The recent estimate of the nephrology workforce indicates that more nephrologists must be trained to care for the increasing number of patients with end-stage renal disease (ESRD). This conclusion was based on a 1996 survey indicating that nephrologists devote an average of 35% of their activities caring for ESRD patients. We compared data in that survey with those from a 1991 survey of members of the American Society of Nephrology to determine similarities between the different periods. The 1,590 responders in the 1991 survey (35% of the American Society of Nephrology membership) indicated that 50% devoted more than 75% of their effort to patient care, predominately for patients with general nephrology and hypertension problems. Approximately 69% of respondents cared for fewer than 50 hemodialysis patients, and the majority of respondents felt the maximum number of dialysis patients for whom they could provide adequate medical care would be 50. Most respondents felt that there would be a deficiency of nephrologists in their community within 5 years. Results from both the 1991 and 1996 surveys indicate that practice patterns have not changed markedly; combining results from the two surveys makes it clear that more nephrologists are needed to care for the projected increase in dialysis patients. Because nephrologists should be involved in the management of the pre-ESRD patient, training programs will have to broaden the preparation of future nephrologists. 相似文献

To define whether age modifies the prognosis of patients with chronic kidney disease (CKD) on nephrology care, we prospectively followed patients with CKD who have been receiving nephrology care in a clinic for 1 year or more. The incidence of end-stage renal disease (ESRD), defined by the occurrence of dialysis or transplant, or death without ESRD was estimated by a competing-risk approach, and interactions between age and risk factors tested in Cox models over a median follow-up period of 62.4 months. Of 1248 patients with stage III–V CKD, 481 were younger than 65, 410 were between 65 and 75, and 357 were over 75 years old. Within each age class, the mean estimated glomerular filtration rate(eGFR) was 31, 32, and 29 ml/min per 1.73 m2, respectively. There were 394 ESRD events and 353 deaths. The risk of ESRD was higher than the risk of death without ESRD for ages <60 years, and independent of eGFR. The ESRD risk diminished with aging but still prevailed for eGFRs of 25–35 in patients between 65 and 75 years and with an eGFR below 15 in those up to 85 years old. Proteinuria significantly increased the risk of ESRD with advancing age. Surprisingly, the unfavorable effects of cardiovascular disease on ESRD and of diabetes on survival significantly decreased with increasing age. Male gender, higher phosphate, lower body mass index, and hemoglobin were age-independent predictors for ESRD, while cardiovascular disease, lower hemoglobin, higher proteinuria and uric acid, and ESRD also predicted death. Thus, in older patients on nephrology care, the risk of ESRD prevailed overmortality even when eGFR was not severely impaired. Proteinuria increases ESRD risk, while the predictive role of other modifiable risk factors was unchanged compared with younger patients. 相似文献

Dialysis providers are capable and interested in participating in the care of CKD patients. But dialysis providers do not, for the most part, become involved in the patients' care until CMS Form 2728 is completed and signed by the attending nephrologist. We believe that dialysis providers are interested in broadening their role, but only if the nephrology community believes this role is appropriate and supports such a resource collaboration. If CMS wants dialysis providers to get more involved in CKD patient management, it is extremely important that this effort not be another unfunded mandate that will result in an increase in the burden on current nursing, dietary, and social work dialysis staff providing current ESRD care. If dialysis providers are to collaborate on CKD care with the nephrology community, they must staff appropriately and there must be a definitive change in the Medicare reimbursement system to support the use of CKD guidelines that will result in a healthier and less costly patient presenting to the dialysis program at the point that they reach end-stage renal disease. 相似文献

CKD is a common condition with well-documented associated morbidity and mortality. Given the substantial disease burden of CKD and the cost of ESRD, interventions to delay progression and decrease comorbidity remain an important part of CKD care. Early referral to nephrologists has been shown to delay progression of CKD. Conversely, late referral has been associated with increased hospitalizations, higher mortality, and worsened secondary outcomes. Late referral to nephrology has been consequent to numerous factors, including the health care system, provider issues, and patient related factors. In addition to timely referral to nephrologists, the optimal modality to provide care for CKD patients has also been evaluated. Multidisciplinary clinics have shown significant improvements in other disease states. Data for the use of these clinics have shown benefit in mortality, progression, and laboratory markers of disease severity. However, studies supporting the use of multidisciplinary clinics in CKD have been mixed. Evidence-based guidelines from groups, including Renal Physicians Association and NKF, provide tools for management of CKD patients by both generalists and nephrologists. Through the use of guidelines, timely referral, and a multidisciplinary approach to care, the ability to provide effective and efficient care for CKD patients can be improved. We present a model to guide a multidisciplinary comanagement approach to providing care to patients with CKD. 相似文献

Despite improvements in dialysis care, mortality of patients with end-stage renal disease (ESRD) remains high. One factor that has thus far received little attention, but might contribute to morbidity and mortality, is the timing of referral to the nephrologist. This study examines the hypothesis that late referral of patients to the nephrologist might lead to suboptimal pre-ESRD care. Clinical and laboratory data were obtained from the patient records and electronic databases of New England Medical Center, its affiliated dialysis unit (Dialysis Clinics, Inc., Boston), and the office records of the outpatient nephrology clinic. Early (ER) and late (LR) referral were defined by the time of first nephrology encounter greater than or less than 4 mo, respectively, before initiation of dialysis. Multivariate models were built to explore factors associated with LR, and whether LR is associated with hypoalbuminemia or late initiation of dialysis. Of the 135 patients, 30 (22%) were referred late. There were no differences in age, gender, race, and cause of ESRD between ER and LR patients. However, there were significant differences in insurance coverage between these two groups. In the multivariate analysis, patients covered by health maintenance organizations were more likely to be referred late (odds ratio = 4.5) than patients covered by Medicare. Compared to ER, LR patients were more likely to have hypoalbuminemia (56% versus 80%), hematocrit <28% (33% versus 55%), and predicted GFR <5 ml/min per 1.73 m2 (17% versus 40%) at the start of dialysis, and less likely to have received erythropoietin (40% versus 17%) or have a functioning permanent vascular access for the first hemodialysis (40% versus 4%). It is concluded that late referral to the nephrologist is common in the United States and is associated with poor pre-ESRD care. Pre-ESRD care of patients treated by nephrologists was also less than ideal. The patient-, physician-, and system-related factors behind this observation are unclear. Meanwhile, pre-ESRD educational efforts need to target patients, generalists, and nephrologists. 相似文献

The need to educate patients in order to enable them to participate in making appropriate choices for all therapeutic options in end stage renal disease would seem obvious yet there are many barriers to providing such information. We measured 'perceived knowledge' of the therapeutic options for end stage renal disease in a cohort of patients with chronic kidney disease in established treatment programs. A self administered questionnaire was given to 676 patients with stage 3-5 chronic kidney disease as part of the CRIOS study designed to identify trends in practice patterns and outcomes over a 4 year period. The median patient age was 66, about three-fourths were Caucasian and almost half were diabetic. When patients were asked to rate their level of knowledge, about one-third reported limited or no understanding of their chronic kidney disease and no awareness regarding their treatment options. A significant and substantial number of patients indicated they had no familiarity with transplant, hemodialysis, and continuous ambulatory or automated peritoneal dialysis. Perceived knowledge improved with the progression of kidney disease and frequency of nephrology visits; however, only about half of patients with 4 or more nephrology appointments in the prior year reported knowing of hemodialysis, continuous ambulatory peritoneal dialysis or transplant. Age, gender and disease had no impact on levels of patient knowledge, but African-Americans reported having significantly less understanding than Asians or Caucasians. These findings suggest that the lack of perception concerning the treatment options chronic kidney and end stage renal disease reflects, in part, problems with the education of patients by nephrologists and not a lack of referral of these patients to nephrologists for care. The discrepancy of perceived knowledge between African-Americans and other races needs special attention. 相似文献

The care of chronic kidney disease patients frequently involves many diagnostic and interventional procedures. Most of these procedures are currently performed by radiologists, vascular surgeons, and general surgeons. This has caused fragmented medical care, which has led many nephrologists to introduce a new paradigm, often referred as interventional nephrology (IN). The aim of this study was to establish the extent of involvement of the Brazilian nephrology community with regard to specific IN procedures. From October 2004 to February 2005, questionnaires were sent by e-mail to all 2500 nephrologists throughout Brazil. The enrollment questionnaire was composed of five sections, with questions about renal biopsy, specific training in ultrasonography, peritoneal dialysis access (insertion of peritoneal catheters guided or not by peritoneoscopy), hemodialysis vascular access (ability to place tunneled catheters, construction of arteriovenous fistulas, and other vascular access procedures), and the nephrologist's interest in being trained in IN. A total of 239 nephrologists answered the questionnaire. Only 18% of Brazilian nephrologists perform kidney biopsy guided by ultrasonography assisted by a radiologist. On the other hand, 42% of them reported that this procedure was done without any image support. Most of the respondents (85%) indicated that they were not formally trained to perform renal ultrasonography. When asked about peritoneal dialysis catheter placement, 66% of the respondents reported that they referred their patients to a surgeon for this procedure. The insertion of peritoneal dialysis catheters guided by peritoneoscopy was reported by 3% of the respondents. Similar to the results for peritoneal dialysis catheter placement, the majority of the respondents (77%) indicated no training in the insertion of tunneled catheters for temporary hemodialysis. Regarding the interest of nephrologists to participate in an IN program, the great majority (87%) responded that they would like to be trained in these procedures. Most nephrologists are not trained in IN procedures. Therefore, in Brazil, it will be necessary to develop training centers for IN that will allow nephrologists to optimize nephrology care. 相似文献

End-stage renal disease (ESRD) is a major health problem in the world, including Cuba. There is an increasing trend in both the incidence and prevalence of ESRD. Global projections consistently show an increase of patients in maintenance dialysis, and also an epidemic trend in diabetes mellitus and hypertension, two diseases that are leading causes of ESRD in most countries. A new paradigm is necessary to handle this major health problem, such as a public health model that integrates health promotion and disease prevention. In 1996, the Ministry of Public Health of Cuba launched a national program for the prevention of chronic renal failure (CRF). The progressive implementation of this program follows several steps: the analysis of the resources and health situation in the country; epidemiological research to define the burden of CRF; continuing education for nephrologists, family doctors, and other health professionals; and reorientation of primary health care toward increased nephrology services, intervention, and surveillance. The main outcomes of the program have been: a rational redistribution of nephrology services in corresponding health areas of primary health care; nephrologists being brought closer to the community; an improvement in the knowledge and ability of family doctors and nephrologists in the prevention of chronic renal disease; an increase in the number of patients with CRF (serum creatinine > or = 133 micromol/L or > or = 1.5 mg/dL, or a glomerular filtration rate < 60 mL/min) who are registered in primary health care every year, from a prevalence of 0.59 per 1,000 inhabitants at the beginning of the program in 1996 to 0.92 per 1,000 inhabitants in 2002, with a mean prevalence growth of 9.2% per year; a significant reduction (0.1%) in the incidence of viral hepatitis B in dialysis patients after the implementation of vaccination against viral hepatitis B in CRF patients who are registered in primary health care; and the implementation of CRF surveillance in primary health care, which provides periodic information on CRF burden, patterns, and trends to assist evidence-based public-health decision making, and measures the impact of interventions in the population. Primary health care is an essential tool, and the community is an appropriate social space for health promotion and the prevention of CRF and ESRD. 相似文献

In the Southern California Kaiser Permanente health plan, all patients having serum creatinine measured will automatically have their GFR reported. Those with reduced GFR are identified and classified into one of the five CKD stages. The PCPs are encouraged to be involved in the care of patients in CKD stages 1-3. Education, guidelines, and algorithms are provided to the PCPs, and nephrology consultation is encouraged. Patients in CKD stage 3 with significant risk factors for developing ESRD and those in CKD stages 4 and 5 are referred to nephrologists. Patients are encouraged to participate [table: see text] in their own care by attending the educational classes provided. 相似文献

In an earlier article in Seminars in Dialysis (9:276–281, 1996), the author described the invention of clinical hemodialysis for acute renal failure and its initially equivocal reception by the emerging specialty of nephrology in the United States. A similar story of blunted enthusiasm played out following the invention of the Quinton–Scribner shunt (whose idea “came in the night”), which allowed maintenance treatment for chronic renal failure. Few centers at first could match Belding Scribner's early successes, and some physiology‐oriented university nephrologists envisioned how routine dialysis might swamp other activities. Nonetheless, increasingly complex and successful inventions appeared and prevailed: the chronic dialysis unit, the national dialysis chain. A unique federal entitlement program fostered the spread of maintenance dialysis, but so did the emergence of disposable off‐the‐shelf supplies and many new nephrologists trained in academia but seeking positions in practice. Indeed, the spread of end‐stage renal disease (ESRD) care transformed American nephrology. The essay concludes by considering what nephrologists of the ESRD era share with their patients. 相似文献

Chronic kidney disease (CKD) is an important and leading cause of end-stage renal disease (ESRD) and moreover, plays a role in the morbidity and mortality due to cardiovascular disease, infection, and cancer. Anemia develops during the early stages of CKD and is common in patients with ESRD. Anemia is an important cause of left ventricular hypertrophy and congestive heart failure. Correction of anemia by erthyropoiesis-stimulating agent (ESA) has been shown to improve survival in patients with congestive heart failure. Anemia is counted as one of the non-conventional risk factors associated with CKD. Hypoxia is one of the common mechanisms of CKD progression. Treatment by ESA is expected to improve quality of life, survival, and prevent the CKD progression. Several clinical studies have shown the beneficial effects of anemia correction on renal outcomes. However, recent prospective trials both in ESRD and in CKD stages 3 and 4 failed to confirm the beneficial effects of correcting anemia on survival. Similarly, treatment of other risk factors such as hyperlipidemia by statin showed no improvement in the survival of dialysis patients. Given the high prevalence of anemia in ESRD and untoward effects of anemia in CKD stages 3 and 4, appropriate and timely intervention on renal anemia using ESA is required for practicing nephrologists and others involved in the care of high-risk population. Lessons from the recent studies are to correct renal anemia (hemoglobin <10 g/dl not hemoglobin > or =13 g/dl). Early intervention for renal anemia is a part of the treatment option in the prevention clinic. In this study, clinical significance of anemia management in patients with CKD is discussed. 相似文献

Establishing guidelines for the appropriate preventive medical care for chronic dialysis patients requires consideration of many factors. These include the population's underlying risk factors and expected survival, the effectiveness of screening procedures in improving the duration and/or quality of life, and the potential for renal transplantation. Although many nephrologists order and direct routine cancer screening in their dialysis patients, recent studies suggest such screening is not cost effective. Cardiovascular disease is the leading cause of death among end-stage renal disease (ESRD) patients and peripheral vascular disease is a leading cause of morbidity among dialysis patients, but even less is known about the cost-effectiveness of screening for peripheral vascular and cardiovascular disease risks in ESRD patients. Despite a recently reported overall standardized cancer incidence of 1.18 in dialysis patients compared with normal populations, the shortened expected survival of dialysis patients argues against routine cancer screening in this population. Dialysis units and nephrologists should focus cancer screening on individual patients and include specific cancer risk as well as expected survival assessments and transplant candidacy in their decisions to screen a patient for cancer. Routine cancer screening of all dialysis patients is not indicated. Additional study of the benefits and cost-effectiveness of screening ESRD patients for cardiovascular and peripheral vascular disease risk factors is needed. 相似文献

BACKGROUND: Early nephrology referral of patients with chronic kidney disease (CKD) has been suggested to reduce mortality after initiation of dialysis. This retrospective cohort study of incident dialysis patients between 1995 and 1998 was performed to address the association between frequency of nephrology care during the 24 months before initiation of dialysis and first-year mortality after initiation of dialysis. METHODS: Patient data were obtained from the Centers for Medicare & Medicaid Services. Patients who started dialysis between 1995 and 1998, and were Medicare-eligible for at least 24 months before initiation of dialysis, were included. One or more nephrology visits during a month was considered a month of nephrology care (MNC). RESULTS: Of the total 109,321 patients, only 50% had received nephrology care during the 24 months before initiation of dialysis. Overall, first-year mortality after initiation of dialysis was 36%. Cardiac disease was the major cause of mortality (46%). After adjusting for comorbidity, higher mortality was associated with increasing age (HR, 1.04 per year increase; 95% CI, 1.03 to 1.04) and more frequent visits to generalists (HR, 1.009 per visit increase; 95% CI, 1.003 to 1.014) and specialists (HR, 1.012 per visit increase; 95% CI, 1.011 to 1.013). Compared to patients with >/=3 MNC in the six months before initiation of dialysis, higher mortality was observed among those with no MNC during the 24 months before initiation of dialysis (HR, 1.51; 95% CI, 1.45 to 1.58), no MNC during the six months before initiation of dialysis (HR, 1.28; 95% CI, 1.20 to 1.36), and one or two MNC during the six months before initiation of dialysis (HR, 1.23; 95% CI, 1.18 to 1.29). CONCLUSION: Nephrology care before dialysis is important, and consistency of care in the immediate six months before dialysis is a predictor of mortality. Consistent nephrology care may be more important than previously thought, particularly because the frequency and severity of CKD complications increase as patients approach dialysis. 相似文献

Early nephrology care may improve treatment outcomes of patients with end-stage renal disease. We sought to examine if physician access affects early nephrology care defined as visiting a nephrologist 12 to 4 months before initiating dialysis. The study population consisted of elderly patients starting hemodialysis whose demographic characteristics and initial dialysis therapy were derived from form 2728 files of the Centers for Medicare & Medicaid Services. Early nephrology care, chronic kidney disease and co-morbidities along with access to local non-nephrologist physicians and nephrologists were identified based on Medicare claims and/or United States 2000 Census data. About one-third of elderly patients received early nephrology care prior to initiating dialysis. Patients living in an area with a large number of non-nephrologist physicians or living relatively far away from a nephrologist had a lower likelihood of getting early nephrology care prior to initiating dialysis while those in an area with more practicing nephrologists were more likely to get early nephrology care. The study shows that physician access significantly influences the use of early nephrology care among elderly patients progressing to end-stage renal disease in the United States. 相似文献

Data from a national survey of 336 nephrologists who provide dialysis care on capitation reimbursement show differences in practice activity associated with the proportion of patients with end-stage renal disease (ESRD). On the average, ESRD patients account for 53% of patients seen by these physicians. Nephrologists who have the majority of their visits with ESRD patients average more than 120 patient encounters per week, approximating the practice workloads of primary care physicians. Nephrologists spend comparable amounts of time providing treatment for ESRD and non-ESRD patients in the same settings, schedule additional office visits for facility dialysis patients, and provide treatment and advice for problems not related to dialysis. Whereas care for acute renal failure patients is primarily based on consultations and involves a narrow focus, treatment for ESRD involves the provision of comprehensive primary medical care by nephrologists to their patients being treated with dialysis. 相似文献

Chronic kidney disease (CKD) is a public health problem in sub-Saharan Africa (SSA) but there is limited data to guide programs or plan interventions. To help set priorities and understand the needs for renal replacement therapy a baseline assessment is required. World Health Organization (WHO) databases and Medline were searched to determine the number of physicians, nephrologists, and dialysis centers and patients in SSA. Data on renal transplant (RTx) programs were collected from the WHO Global Observatory on Donation & Transplantation database for deceased-donor and living-donor RTx. Of the 47 countries in SSA only 15 had recent data with most rates of physicians per 10,000 population under 2.0. Nigeria and South Africa had the greatest absolute numbers of physicians and nephrologists but Mauritius had the greatest proportion to population. South Africa had the most dialysis patients. Kenya, Nigeria and South Africa were the only countries with RTx programs and reported rates per million population of 0.60, 0.23 and 5.12, respectively. Treatment for patients with CKD in SSA is limited by a lack of physicians, nephrologists, and dialysis centers. Few countries are performing RTx. Resources are needed to increase the health workforce and increase RTx programs in SSA. 相似文献
