BACKGROUND: A nephrologist in the millennium offers comprehensive care to renal failure patients. Interventional nephrology plays a major role in this new approach. Overton Brooks Veterans Affairs Medical Center (OBVAMC) is the first federal health care provider in the nation offering such services. Lack of interventional radiologists and a busy surgical service has catalyzed the existence of interventional nephrology at this center. We report our early experience in successfully providing complete care to veterans with renal failure, despite multiple logistical obstacles. METHOD: The OBVAMC is an acute care facility providing nephrology support to hospitalized veterans and also handles access-related issues for eligible chronic dialysis patients. All procedures performed from June 2000 to September 2003 were analyzed. The procedures were performed in the cardiac catheterization laboratory or in the surgical operating rooms. RESULTS: A total of 366 procedures were performed, which included: 110 tunneled cuffed catheter (TCC) placements, 157 temporary dual lumen catheters, 36 TCC removals, 30 fistulograms, 24 thrombectomy-/angioplasty, 1 stent placement, 3 Tenckhoff catheter placements, 3 central venograms, and 2 accessory vein ligations. Bleeding from the exit site of a TCC in one patient was the only complication encountered. CONCLUSION: Interventional nephrology experience at OBVAMC has been very encouraging and has succeeded in providing optimal care to the veterans. Interventional nephrology programs can be developed in any tertiary care hospital. 相似文献

BACKGROUND AND OBJECTIVES: After total knee arthroplasty (TKA), hospitalization may be shortened by allowing patients to return home with a continuous femoral nerve block (CFNB). This study quantified the hospitalization costs for 10 TKA patients receiving ambulatory CFNB versus a matched cohort of 10 patients who received CFNB only during hospitalization. METHODS: We examined the medical records (n = 125) of patients who underwent a unilateral, primary, tricompartment TKA with a postoperative CFNB by 1 surgeon at one institution in an 18-month period beginning January 2004. Each of the 10 patients discharged home with an ambulatory CFNB (cases) was matched with a patient with a hospital-only CFNB (controls) for age, gender, body mass index, and health status. Financial data were extracted from the hospital microcosting database. RESULTS: Nine patients with ambulatory CFNB (cases) were discharged home on postoperative day (POD) 1 and 1 on POD 4. Of the controls, 3 were discharged home on POD 3, 6 on POD 4, and 1 on POD 5. The median (range) costs of hospitalization (excluding implant and professional fees) was US dollars 5,292 (US dollars 4,326-US dollars 7,929) for ambulatory cases compared with US dollars 7,974 (US dollars 6,931-US dollars 9,979) for inpatient controls (difference = US dollars 2,682, 34% decrease, P < .001). The total charges for hospitalization, the implant, and professional fees was US dollars 33,646 (US dollars 31,816-US dollars 38,468) for cases compared with US dollars 39,100 (US dollars 36,096-US dollars 44,098) for controls (difference = US dollars 5,454, 14% decrease, P < .001). CONCLUSIONS: This study provides evidence that ambulatory CFNB for selected patients undergoing TKA has the potential to reduce hospital length of stay and associated costs and charges. However, the current study has significant inherent limitations based on the study design. Additional research is required to replicate these results in a prospective, randomized, controlled trial and to determine whether any savings exceed additional CFNB costs such as from complications, having caregivers provide care at home, and additional hospital/health care provider visits. 相似文献

The Economic Implications of Noninvasive Molecular Testing for Cardiac Allograft Rejection 总被引:2,自引:0,他引:2
Roger W. Evans Gavin E. Williams Helen M. Baron Mario C. Deng Howard J. Eisen Sharon A. Hunt Mahmud M. Khan Jon A. Kobashigawa Eric N. Marton Mandeep R. Mehra Seema R. Mital 《American journal of transplantation》2005,5(6):1553-1558
Endomyocardial biopsy is the mainstay for monitoring cardiac allograft rejection. A noninvasive strategy--peripheral blood gene expression profiling of circulating leukocytes--is an alternative with proven benefits, but unclear economic implications. Financial data were obtained from five cardiac transplant centers. An economic evaluation was conducted to compare the costs of outpatient biopsy with those of a noninvasive approach to monitoring cardiac allograft rejection. Hospital outpatient biopsy costs averaged 3297 US dollars, excluding reimbursement for professional fees. Costs to Medicare and private payers averaged 3581 US dollars and 4140 US dollars, respectively. A noninvasive monitoring test can reduce biopsy utilization. The savings to health care payers in the United States can be conservatively estimated at approximately 12.0 million US dollars annually. Molecular testing using gene expression profiling of peripheral circulating leukocytes is a new technology that offers physicians a noninvasive, less expensive alternative to endomyocardial biopsy for monitoring allograft rejection in cardiac transplant patients. 相似文献

The field of interventional nephrology is rapidly developing as an important new area of nephrology practice that holds great promise for improved patient care, outcomes, and cost control. This development is contingent on nephrologists acquiring the necessary knowledge and skills through suitable training and experience, and obtaining hospital privileges to perform these interventions. As more training programs are created, and credentialing criteria are established and accepted, it will become more practical for nephrologists to become interventionists. Reimbursement for interventional procedures can be complicated and confusing, with special problems applicable to a nephrology practice involved in the overall care of end-stage renal disease (ESRD) patients. It is essential to become familiar with applicable procedure codes, global periods, and code modifiers to correctly describe these procedures and receive correct reimbursement. Nephrologists work together with vascular access surgeons and interventional radiologists to provide care for dialysis patients. The role of each specialist in the management of vascular access depends on his or her level of interest, knowledge, and technical skill. These roles may vary considerably from one practice to another. There is potential for this area to become highly contentious, especially if one specialist feels threatened by the activities of another. Optimal patient care will be achieved only if all involved physicians take a serious intellectual interest in vascular access, develop superior clinical skills, and maintain cooperative, collegial, relationships. 相似文献

OBJECTIVE: Patients demand that health care and procedures in rural areas be provided by ambulatory surgery centers close to home. However, the reimbursement rate for such procedures in ambulatory centers is extremely low, so a standard classic intrafascial supracervical hysterectomy procedure needs to be more cost effective to be performed there. Instruments and disposable devices can make up > or = 50% of hospital costs for this procedure, so any cost reduction has to focus on this aspect. METHODS: We identified the 3 most expensive disposable devices: (1) an Endostapler, 498 US dollars and 3 staple reloads, 179 US dollars each; (2) a calibrated uterine resection tool 15 mm for encoring of the endocervical canal, 853 US dollars; and (3) a serrated edged macro morcellator for intraabdominal uterus morcellation, 321 US dollars, and substituted them using classic conservative surgical techniques. RESULTS: From September 2001 to September 2002, we performed 26 procedures with this modified technique at an ambulatory surgery center with a follow-up of 6.7 (2 to 14) months. This modified operative technique was feasible; no conversions were necessary, and no complications occurred. Cost savings were 2209 US dollars per procedure; additional costs were 266.33 US dollars for suture material and an Endopouch, resulting in an overall savings of 50 509.42 US dollars. The disadvantage was an increase in operating room time of about 1 hour 20 minutes per case. CONCLUSION: These modifications in the classic intrafascial supracervical hysterectomy technique have proven to be feasible, safe, and highly cost effective, especially for a rural ambulatory surgery center. Long-term follow-up is necessary to further evaluate these operative modifications. 相似文献

OBJECTIVES: Reduction of length of stay (LOS) is critical for optimal use of hospital resources. We developed and evaluated a system to aggressively reduce LOS for vascular surgery. METHOD: Key to this system, which we introduced on January 1, 2001, was appointment of a LOS officer, who communicated daily during hospitalization with patients and families about discharge planning, organized outpatient services for wound care and rehabilitation to transition patients quickly to nonhospital care, and had biweekly meetings with relevant paramedical services. LOS for 509 patients operated on in 2000 (standard group) was compared with LOS for 474 operated on in 2001 and 595 patients operated on in 2002 (LOS reduction groups). Data for all patients with aortic aneurysm, carotid artery stenosis, lower extremity critical ischemia or amputation, and foot debridement were included. RESULTS: LOS in 2000 averaged 8.5 days, compared with 5.9 days in 2001 and 5.6 days in 2002. All decreases in LOS for each diagnostic category in 2001 and 2002 were statistically significant (P = <.001-.03). There was no significant increase in readmission rate (2.2% vs 1.9% and 2.0%, respectively), mortality rate (0.8% vs 0.6% and 0.7%, respectively), or percent of patients who received endovascular treatment (18% vs 16% and 14%, respectively). These decreases in LOS saved the hospital more than US dollars 616200 in 2001, and US dollars 847550 in 2002 (US dollars 500/patient-day). CONCLUSIONS: A committed LOS officer with major specific daily responsibilities for decreasing LOS and discharging patients resulted in a 31% to 33% decrease in LOS, with important cost savings to the hospital and no negative effect on patient care. 相似文献

OBJECTIVES: Compare cost/benefits of organizational restructuring of the cardiac intensive care unit (CICU). DESIGN: Prospective, with a retrospective control period. SETTING: Academic medical center. Participants: Sixty-six CICU patients (prospective) and 57 patients who received care before restructuring (retrospective) were compared. Entrance criteria were constant for both study periods. INTERVENTIONS: The CICU was restructured from a level III ICU to a level I ICU with the initiation of a consultant CICU service. The CICU service provided an attending physician dedicated to ICU care daily. All cardiac patients admitted into the CICU received consultation by the CICU service. MEASUREMENTS AND MAIN RESULTS: The average postoperative intubation time decreased during the intervention period (61% extubated within 6 hours v 12%, p = 0.004). Pharmacy, radiology, laboratory, and ICU costs decreased 279 US dollars (p = 0.004), 196 US dollars (p = 0.003), 190 US dollars (p = 0.15), and 470 US dollars (p = 0.12), respectively. The ICU length of stay (0.28 days shorter) as well as the overall postsurgery stay (0.54 days shorter) were reduced in the intervention period (p = 0.11 and 0.10, respectively). CONCLUSIONS: The CICU service significantly reduced both total ICU-related costs ($1,173/patient) and overall costs (2,285 US dollars/patient) during the intervention period. Professional fees only reduced overall savings by 8%. These results indicate that organizational restructuring of the CICU to newer models can reduce costs associated with cardiac surgery. 相似文献

In the early 1950s and 1960s, peritoneal dialysis (PD) was used primarily to treat patients with acute renal failure. Continuous ambulatory peritoneal dialysis (CAPD) was introduced in 1976 and continues to gain popularity as an effective method of renal replacement therapy for patients with end-stage renal disease (ESRD). The PD catheter is inserted into the abdominal cavity either by a surgeon, interventional radiologist, or nephrologist. We have adopted a percutaneous approach with fluoroscopic guidance for PD catheter insertion that is easy, safe, and provides good patency and infection rate results. In this article we describe the technique and our results. From August 2000 to May 2003, 34 PD catheters out of 36 were successfully inserted using the percutaneous fluoroscopic technique in selected patients referred from the nephrology clinic. All the PD catheters were placed in our Interventional Nephrology Vascular Suite by nephrologists. 相似文献

Vascular access is emerging as a critical issue for hemodialysis patients in Puerto Rico. In more than 50% of the hemodialysis patients, tunneled hemodialysis catheters are the sole access for providing dialysis therapy. Most disturbing is the fact that a significant number of these catheters are nontunneled temporary catheters, sometimes placed in the subclavian vein. These facts have contributed significantly to the morbidity and mortality seen in chronic dialysis patients. In addition, many cases of early or late dysfunction of arteriovenous access are not detected and treated in a timely manner due to the lack of a comprehensive vascular access program for end-stage renal disease (ESRD) patients. In fact, monitoring programs to identify and detect vascular access dysfunction are virtually nonexistent in many chronic dialysis units. Even when diagnosed, it is not treated in a timely fashion. Recently literature has shown that procedure-related delays in the treatment of patients with renal disease can be minimized and nephrology care more efficiently delivered by a nephrologist trained in nephrology-related procedures. In an effort to optimize the care of our ESRD patients, we took the initiative to develop an interventional nephrology program that effectively deals with vascular access-related procedures in a timely manner. This approach has minimized delays, decreased hospitalizations and the use of temporary catheters, and improved the medical care of our chronic dialysis patients. So far we have performed more than 400 procedures in the 6 months since the initiation of the program. In this article we describe our initial experience with interventional nephrology in Puerto Rico. 相似文献

Aim: Late referral of chronic kidney disease (CKD) patients to nephrologists is associated with increased morbidity and mortality and is still quite common and seldom studied in Taiwan because of unique sociocultural factors. We aimed to study the decline in renal function and factors related to the change in renal function before and after referral. Methods: We retrospectively reviewed the changes of estimated glomerular filtration rate (eGFR) in 213 new referrals of patients with CKD stages 3–5 to the nephrology divisions of one medical centre and one regional hospital from 2001–2006. Data on demographics and laboratory investigations were collected for study. Results: The rates of annual eGFR decline slowed significantly from −7.38 ± 0.84 before referral to −1.02 ± 0.45 mL/min per 1.73 m2/year after referral (mean ± standard error of the mean, P < 0.001). The nephrology referral was the most significant factor associated with the slowing of renal function progression, as was younger age and female sex. After nephrology referral, patients with diabetes had an increase in eGFR compared to those without diabetes (P = 0.034). Patients had better control of diastolic blood pressure, sugar and lipid, more frequent use of angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers and statins, less frequent use of non-steroidal anti-inflammatory drugs, and more serum creatinine measurements after nephrology referral. Conclusion: Slowing renal functional decline in CKD patients after referral addresses the importance of nephrology referral for CKD care, which should be strongly promoted in CKD prevention projects in Taiwan. 相似文献

OBJECTIVE: To determine if brief alcohol interventions in trauma centers reduce health care costs. SUMMARY BACKGROUND DATA: Alcohol-use disorders are the leading cause of injury. Brief interventions in trauma patients reduce subsequent alcohol intake and injury recidivism but have not yet been widely implemented. METHODS: This was a cost-benefit analysis. The study population consisted of injured patients treated in an emergency department or admitted to a hospital. The analysis was restricted to direct injury-related medical costs only so that it would be most meaningful to hospitals, insurers, and government agencies responsible for health care costs. Underlying assumptions used to arrive at future benefits, including costs, injury rates, and intervention effectiveness, were derived from published nationwide databases, epidemiologic, and clinical trial data. Model parameters were examined with 1-way sensitivity analyses, and the cost-benefit ratio was calculated. Monte Carlo analysis was used to determine the strategy-selection confidence intervals. RESULTS: An estimated 27% of all injured adult patients are candidates for a brief alcohol intervention. The net cost savings of the intervention was 89 US dollars per patient screened, or 330 US dollars for each patient offered an intervention. The benefit in reduced health expenditures resulted in savings of 3.81 US dollars for every 1.00 US dollar spent on screening and intervention. This finding was robust to various assumptions regarding probability of accepting an intervention, cost of screening and intervention, and risk of injury recidivism. Monte Carlo simulations found that offering a brief intervention would save health care costs in 91.5% of simulated runs. If interventions were routinely offered to eligible injured adult patients nationwide, the potential net savings could approach 1.82 billion US dollars annually. CONCLUSIONS: Screening and brief intervention for alcohol problems in trauma patients is cost-effective and should be routinely implemented. 相似文献

OBJECTIVES: We examined economic and practice trends after 5 years of a merger between vascular surgeons and interventional radiologists. METHODS: In 1998 a merger between the Division of Vascular Surgery and the Section of Interventional Radiology at the University of Rochester established the Center for Vascular Disease (CVD). Business activity was administered from the offices of the vascular surgeons. RESULTS: In 1998 the CVD included five vascular surgeons and three interventional radiologists, who generated a total income of $5,789,311 US dollars (34% from vascular surgeons, 24% from interventional radiologists, 42% from vascular laboratories). Vascular surgeon participation in endoluminal therapy was limited to repair of abdominal aortic aneurysms (AAAs). Income was derived from 1011 major vascular procedures, 10,510 catheter-based procedures in 3286 patients, and 1 inpatient and 3 outpatient vascular laboratory tests. In 2002 there were six vascular surgeons (five, full-time equivalent) and four interventional radiologists, and total income was $6,550,463 US dollars despite significant reductions in unit value reimbursement over the 5 years, a 4% reduction in the number of major vascular procedures, and a 13% reduction in income from vascular laboratories. In 2002 the number of endoluminal procedures increased to 16,026 in 7131 patients, and contributions to CVD income increased from 24% in 1998 to 31% in 2002. Three of the six vascular surgeons performed endoluminal procedures in 634 patients in 2002, compared with none in 1998. CONCLUSIONS: Gross revenues increased in a declining reimbursement and conventional practice environment, because of the increased number of endoluminal procedures, in part provided by vascular surgeons. The implications of these data should be considered by those responsible for training vascular surgeons. 相似文献

Ultrasonography (US) is becoming increasingly utilized in the United States for the evaluation of blunt abdominal trauma (BAT). The objective of this study was to assess the cost impact of utilizing US in the evaluation of patients with BAT in a major trauma center. All patients sustaining BAT during a 6-month period before US was used at our institution (Jan-Jun 1993) were compared to BAT patients from a recent period in which US has been utilized (Jan-Jun 1995). The numbers of US, computed tomography (CT), and diagnostic peritoneal lavage (DPL) were tabulated for each group. Financial cost for each of these procedures as determined by our finance department were as follows: US $96, CT $494, DPL $137. These numbers are representative of actual hospital expenditures exclusive of physician fees as calculated in 1994 U.S. dollars. Cost analysis was performed with t test and chi squared test, and significance was defined as P < 0.05. There were 890 BAT admissions in the 1993 study period and 1033 admissions in the 1995 study period. During the 1993 period, 642 procedures were performed on the 890 patients to evaluate the abdomen: 0 US, 466 CT, and 176 DPL (see table) [table: see text]. This compares to 801 procedures on the 1,033 patients in 1995: 552 US, 228 CT, and 21 DPL. Total cost was $254,316 for the 1993 group and $168,501 for the 1995 group. Extrapolated to a 1-year period, a significant (P < 0.05) cost savings of $171,630 would be realized. Cost per patient evaluated was significantly reduced from $285.75 in 1993 to $163.12 in 1995 (P < 0.05). This represents a 43 per cent reduction in per patient expenditure for evaluating the abdomen. By effectively utilizing ultrasonography in the evaluation of patients with blunt abdominal trauma, a significant cost savings can be realized. This effect results chiefly from an eight-fold reduction in the use of DPL, and a two-fold reduction in the use of CT. 相似文献

In recent years, nephrologists have taken the initiative of performing vascular access-related procedures themselves. Because of their unique clinical perspective on dialysis access and better understanding of the intricacies of renal replacement therapy, nephrologists are ideally suited for this activity. This approach has minimized delays, decreased hospitalizations and decreased the use of temporary catheters, thereby improving medical care, decreasing costs and increasing patient convenience. Vascular access interventions commonly employed by nephrologists include vascular access education, vascular mapping, percutaneous balloon angioplasty, thrombectomy, intravascular coil and stent insertion and tunneled hemodialysis catheter-related procedures. While the performance of these procedures by nephrologists offers many advantages, appropriate training to develop the necessary procedural skills is critical. Recent data have emphasized that a nephrologist can be successfully trained to become a competent interventionalist. In addition to documenting excellent outcome data, multiple reports have demonstrated the safety and success of an interventional nephrology approach. The last decade has been a period of significant advances in this new field. This has been driven in part by the formation of the American Society of Diagnostic and Interventional Nephrology (ASDIN), whose mission includes training, quality assurance and certification. Recently, the ASDIN has published guidelines for training in nephrology-related procedures and has begun certifying physicians in specific procedures related to chronic kidney disease. It is anticipated that this will promote the skillful performance of these procedures by nephrologists and lead to substantial improvements in the care of renal patients. Challenges for the future include awareness of this subspecialty and development of training programs at academic centers on a larger scale. 相似文献

OBJECTIVE: The pace of implementation of a laparoscopic nephrectomy programme is affected by factors including surgical expertise, case load, learning curves and outcome audits. We report our experience in introducing a laparoscopic nephrectomy programme over a 3-year period. METHODS: From January 2001 to December 2003, 187 nephrectomies were performed (105 by conventional surgery, 82 by laparoscopy). Hand-assisted laparoscopy was used predominantly. The indications for surgery, factors affecting the approach and outcome parameters were studied. A cost comparison was made between patients with similar-sized renal tumours undergoing laparoscopic versus open surgery. RESULTS: Most operations were performed for malignancy in both the open (70%) and laparoscopic (67%) surgery groups. The laparoscopic approach was most commonly used in upper tract transitional cell cancers (TCCs; 70% of 30 patients) and benign pathologies (49% of 35 patients), followed by radical nephrectomies (34% of 99 patients) and donor nephrectomies (44% of 23 patients). There was a rapid rise in laparoscopic surgeries, from 30% in 2001 to 58% in 2002. The median hospital stay was 5.8 days in the laparoscopic group and 8.1 days in the open surgery group. The procedure cost for laparoscopic surgery was 4,943 dollars compared with 4,479 dollars for open surgery. However, due to a shorter hospital stay, the total hospital cost was slightly lower in the laparoscopic group (7,500 dollars versus 7,907 dollars). CONCLUSION: The laparoscopic approach for various renal pathologies was quickly established with a rapid increase in the number of laparoscopic procedures. 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

Revision total hip arthroplasty is a complex surgical procedure that frequently requires high levels of hospital resources. The purpose of the current study was to report the actual costs and reimbursement to the hospital for a stratified group of patients having revision total hip arthroplasty based on a severity index. The clinical and financial records of 49 patients (51 hips) stratified by complexity of revision were reviewed. Clinical variable included age, length of stay, operating time, estimated blood loss, number of transfusions, implant type, metallic augmentation, use of bone graft, and time spent in the postanesthesia care unit. Financial review included the actual fixed and variable costs associated with each procedure. Hospital costs associated with revision total hip arthroplasty were significantly greater in the most complex revisions and in older patients. The use of bone grafting techniques on the femur resulted in significantly greater costs. The average loss to the hospital was $5402 US dollars per procedure with a range of $5657 (US dollars) profit to $28,780 (US dollars) loss. Procedures in patients younger than 65 years has an average loss of $1133 US dollars. All procedures in patients who were 65 years or older resulted in a loss to the hospital, with the average loss being $8617 US dollars. Despite improvements in length of stay, use of clinical pathways, and negotiated discounts on implants, the hospital loss on each hip revision procedure averaged $5402 US dollars. 相似文献

The development of interventional nephrology has undoubtedly led to an improvement in patient care at many facilities across the United States. However, these services have traditionally been offered by interventional nephrologists in the private practice arena. While interventional nephrology was born in the private practice setting, several academic medical centers across the United States have now developed interventional nephrology programs. University Medical Centers (UMCs) that offer interventional nephrology face challenges, such as smaller dialysis populations, limited financial resources, and real or perceived political "turf" issues." Despite these hurdles, several UMCs have successfully established interventional nephrology as an intricate part of a larger nephrology program. This has largely been accomplished by consolidating available resources and collaborating with other specialties irrespective of the size of the dialysis population. The collaboration with other specialties also offers an opportunity to perform advanced procedures, such as application of excimer laser and endovascular ultrasound. As more UMCs establish interventional nephrology programs, opportunities for developing standardized training centers will improve, resulting in better quality and availability of nephrology-related procedures, and providing an impetus for research activities. 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

Obtaining renal tissue is often critical in the diagnosis and management of patients with renal disease of unknown etiology. Bleeding diathesis, liver disease, and obesity are common contraindications for percutaneous renal biopsy. In high-risk patients, transjugular renal biopsy is believed to be a safe and effective procedure. This study reports the experience of an academic interventional nephrology program with performing transjugular renal biopsy. We performed a retrospective observational study of 23 patients with either acute or chronic kidney disease with contraindications for percutaneous renal biopsy. All transjugular renal biopsies were performed by interventional nephrologists at our university. We studied the efficacy and safety of transjugular renal biopsy in these patients. Twenty out of 23 (87%) of the procedures yielded adequate tissue for pathologic diagnosis. Three (13%) patients required blood transfusions, none required coil embolization or nephrectomy, and there were no deaths. Even though performing transjugular renal biopsy requires considerable technical expertise and must be performed in an interventional radiology suite, it can be safely and effectively performed by well-trained interventional nephrologists to achieve pathological diagnosis. 相似文献
