Hospitalization rate is high in patients on chronic hemodialysis (HD). We investigated whether initiation of HD changes the rate and length of hospitalization. We analyzed hospitalizations in HD patients in one hospital over 15 years. We compared annual rate and length of hospitalizations, both presented as mean (95% confidence interval [CI]) between the pre-HD and HD period. Three hundred ninety-two patients, 98% men, 59% diabetic, and 66.3 ± 11.2 years old at the onset of HD, had 1016 hospitalizations in the pre-HD period (60.0 ± 42.9 months) and 1627 hospitalizations in the HD period (32.5 ± 25.9 months). Higher values were found in the HD than the pre-HD period for rate, (pre-HD 0.557 [95% CI 0.473-0.611], HD 2.198 [95% CI 1.997-2.399] admissions/[patient-year], P<0.001) and length (pre-HD 4.63 [95% CI 3.71-5.55], HD 28.07 [95% CI 23.55-32.59] days/patient-year], P<0.001) of hospitalizations for all causes, cardiac disease, infections, vascular access, peripheral vascular disease, metabolic disturbances, gastrointestinal diseases, and miscellaneous conditions, mainly respiratory illness and malignancy. Similar differences were found when we compared the year before and the year after the start of HD. Diabetics had higher all cause rate and length of hospitalizations than non-diabetics in the pre-HD and HD periods. The rate and length of hospitalizations was higher in the HD than the pre-HD period for both HD-specific conditions and conditions encountered in both HD and general populations. Study of factors specific to HD that may affect these conditions should constitute the first step toward improving the morbidity of patients on HD. 相似文献

Low and not high cholesterol seems to predict high mortality in hemodialysis (HD) patients. The confirmation of this reverse epidemiology as well as its possible interconnection with the increased inflammatory activity observed in this population is being explored in the present study. A group of 136 HD patients was prospectively studied for 2 years, and cardiovascular disease (CVD) as well as all-cause mortality and morbidity were recorded. Baseline lipid profile, inflammatory status, and patients' characteristics were studied as potential survival and hospitalization predictors. During the 24-month follow-up, 21 deaths (52.4% due to CVD) and 38 hospitalizations (55.3% due to CVD) were recorded. In multivariate Cox regression analysis, decreased interleukin-10 (IL-10) and decreased total serum cholesterol (TChol) were the only independent predictors of CVD mortality while C-reactive protein and decreased TChol predicted all-cause mortality. Interleukin-10 at baseline was 11.29 ± 21.49 vs. 5.51 ± 4.57 pg/mL (P<0.018) and TChol 167.37 ± 47.84 vs.122.04 ± 26.48 mg/dL (P<0.000) in survivors vs. nonsurvivors from CVD, while C-reactive protein at baseline was 9.37 ± 11.54 vs. 23.15 ± 18.76 mg/L (P<0.000) and TChol 169.26 ± 46.42 vs. 133.26 ± 46.33 mg/dL (P<0.003) in survivors vs. nonsurvivors from any cause of death. Using the same method of statistical analysis, IL-6 and decreased soluble gp130 (sgp130)—an antagonist of IL-6 action—were found to be the only independent prognostic factors for hospitalization due to CVD while decreased soluble gp130 remained the sole predictor of hospitalization due to any cause. In conclusion, reverse epidemiology regarding cholesterol is confirmed in the present study. Furthermore, inflammatory activity also predicts, independently of or in conjunction with low-cholesterol, CVD and all-cause morbidity and mortality in HD patients. 相似文献

Introduction: The Kidney Disease Outcomes Quality Initiative (K/DOQI) has established target hemoglobin (Hb) level of 11–12 g/dL for all dialysis patients. For patients who leave an inpatient hospitalization with an Hb under this target, it is hypothesized that several factors contribute to the length of time required to achieve an Hb of 11 g/dL after hospitalization.
Objective: To identify factors contributing to a decreased likelihood of reaching this target Hb.
Methods: Using the first hospitalization of patients who initiated HD in 1999 and who were regularly treated with EPO, we identified those with a mean Hb of less than 11 g/dL on EPO claims during the same month as their index hospitalization. Patients were then followed up to see how long it took them to achieve an Hb of 11 g/dL, censored at death, re-hospitalization, a switch of modality, or suspension of EPO treatment.
Results: A total of 6050 HD patients were identified. 3 months after hospitalization, 70% had achieved 11 g/dL, and 12% had been censored. For the remaining patients who eventually reached 11 g/dL, the average number of additional months required was 2.69 (SE of 0.09). From proportional hazards regression on the time (in months) to achieving an Hb of 11 g/dL, factors that significantly decreased the likelihood of reaching a target Hb included: a diagnosis on the index hospitalization of CHF or hepatic disease, a low Hb prior to the hospitalization, a high dose of EPO prior to the hospitalization, and a longer hospital stay.
Conclusions: Patients with anemia after hospitalization are at high risk of both persistent anemia and rehospitalization. It is important to address patient comorbidities, to ensure adequate medication usage, and to monitor patient progress to prevent hospitalizations and potential impact on Hb levels. 相似文献

Introduction: A structured predialysis multidisciplinary team program is beneficial in improving quality of life in patients with end‐stage renal disease (ESRD). Educating pre‐ESRD patients about their disease is vital in their care. Patients who can identify signs and symptoms of impending problems can seek help and avoid complications that may lead to hospital admissions. Our dialysis center offers two predialysis classes in a structured format. The first class is for those patients with mild to moderate renal disease, whereas the second class is for those with advanced renal disease who are expected to need dialysis in 3 to 6 months. The patients are followed by a multidisciplinary team once they are enrolled in our chronic kidney disease program. Methods: We retrospectively reviewed all the charts of patients who started dialysis at our center between 1997 and 2000. We identified 68 patients who participated in the predialysis education program and 35 patients who did not because of late referral or refusal to participate. We compared these two groups over a 100‐day period (10 days before initial dialysis and 90 days after), for hospitalizations, emergency room (ER) visits, and dialysis access placement. Patients' comorbid conditions, complications, and length of hospitalizations were extracted from the medical records. Results: The 68 patients who completed the predialysis program had an average age of 60.3 years, a total of 96 hospital days, and 39 ER visits. Average length of hospital stay for these patients was 1.4 days. Three patients (4.4%) required placement of temporary catheters for the initial dialysis. Fifty‐one percent of these patients had diabetes mellitus. The 35 patients of average age of 54.9 years who did not go through the program had 347 total hospital days and 39 ER visits. Average length of hospitalization was 9.9 days. Thirteen patients (37%) required temporary catheters for initial dialysis. This group included 16 patients (45.7%) with diabetes. Conclusion: Patients who participated in a multidisciplinary predialysis education program had fewer complications, ER visits, and hospitalizations. They also had fewer temporary catheter placements, shorter hospital stays, and reduced costs associated with initial dialysis. 相似文献

Chronic kidney disease (CKD) patients with established nephrology care have a high rate of tunneled dialysis catheters (TDC) as first vascular access when transitioning to hemodialysis (HD). We sought to identify factors associated with this problem. Patients who started HD and had prior CKD care within our renal clinic were categorized according to access type at incident HD. Clinical factors, all estimated glomerular filtration rates (eGFR), renal clinic attendance records, hospital admissions in the 6 months preceding HD start, and patient participation in predialysis education course were analyzed. Three hundred thirty‐eight patients initiated HD, 107 received pre‐HD CKD care within our clinics. Seventy patients started with a TDC. All groups started HD at similar eGFR values. The trajectory of eGFR decline in the 6 months prior to HD start was significantly more rapid in the TDC group. Patients in the TDC group had more acute health events in the prior 6 months. Multivariate modeling showed that failure to attend a predialysis education course and having a more rapid rate of eGFR decline in the 6 months prior to dialysis initiation were both associated with TDC use. Patients with CKD nephrology care who initiated HD with a TDC as first vascular access had a more rapid rate of decline in eGFR in the months preceding dialysis start and were less likely to have attended our predialysis education course. This appears to correspond with the observed increased number of emergency and hospital visits in the 6 months prior to end‐stage renal disease. 相似文献

Patients with hemodialysis (HD) are at risk of death due to cardiac arrhythmias, worsening congestive heart failure (CHF), and noncardiac causes. This study reviews our experience with the use of implantable cardioverter defibrillators (ICDs) in patients with ventricular tachycardia who are under maintenance HD. We retrospectively reviewed 71 consecutive patients who underwent an ICD implantation in our hospital. There were 11 patients under maintenance HD and 60 patients without HD. The group of patients with HD (HD group) was compared with the patients without HD (control group). The mean follow-up period was 30±9 vs. 39±4 months in the HD group vs. the control group, respectively. Among these patients, 6 in the HD group and 26 in the control group received appropriate ICD therapies. There was no difference in appropriate ICD therapy, time to the first therapy, and electrical storm between the 2 groups. In the HD group, 1 patient underwent surgical removal of the ICD system due to infective endocarditis. There were 5 deaths in the HD group (4 from CHF) and 8 deaths in the control group (4 from CHF). There were no sudden cardiac deaths or arrhythmic deaths in both groups of patients during the follow-up period. However, the overall death rate was significantly higher in the HD group (P<0.01). In HD patients, ICD therapy prevented arrhythmic death, but their rate of nonarrhythmic adverse outcomes was high. This risk-benefit association should be considered before implantation of the device. 相似文献

Clinical performance measures, including dialysis dose, hemoglobin, albumin, and vascular access, are the focus of monitoring and quality improvement activities. However, little is known about the implications of clinical performance measures for hospital utilization and health care costs. We obtained clinical performance measures and hospitalization records for a national random sample of 10,650 hemodialysis patients and analyzed the relationship between changes in clinical performance measures and hospital utilization after adjustment for patient demographic and medical characteristics. Higher hemoglobin, higher albumin, and fistula or graft use were independently associated with fewer hospitalizations, fewer hospital days, and decreased Medicare inpatient reimbursement. For example, a 0.5 g/dL higher hemoglobin, a 0.25 g/dL higher albumin, fistula use, and graft use were associated with hospitalization rate ratios of 0.90 (95% confidence interval 0.85, 0.96), 0.64 (0.53, 0.77), 0.60 (0.52, 0.69), and 0.79 (0.71, 0.89), respectively. Moreover, there was a 2-3-fold variation in hospital utilization across end-stage renal disease networks that was still evident after adjustment for patient characteristics and clinical performance measures. Clinical performance measures, especially albumin and vascular access, are strongly associated with hospital utilization and health care costs. These results highlight the importance of targeting nutrition and vascular access in quality improvement efforts. The marked variation in hospital utilization across networks deserves further examination. 相似文献

Many patients with end‐stage renal disease have significant impairment in health‐related quality of life (HRQoL). Most previous studies have focused on clinical factors; however, quality of life can also be affected by psychosocial factors. The aim of this study was to identify the possible predictors of HRQoL among clinical and psychosocial factors in hemodialysis (HD) patients. The study included 101 patients who were undergoing HD. Psychosocial factors were evaluated using the Hospital Anxiety and Depression Scale, Multidimensional Scale of Perceived Social Support, Montreal Cognitive Assessment, and Pittsburgh Sleep Quality Index. We also assessed laboratory and clinical factors, including albumin, Kt/V as a marker of dialysis adequacy, normalized protein catabolic rate, and duration of HD. The Euro Quality of Life Questionnaire 5‐Dimensional Classification (EQ‐5D) was used to evaluate HRQoL. The mean EQ‐5D index score was 0.704 ± 0.199. The following variables showed a significant association with the EQ‐5D index: age (P < 0.001), depression (P < 0.001), anxiety (P < 0.001), support from friends (P < 0.001), cognitive function (P < 0.001), duration of HD (P = 0.034), triglyceride (P = 0.031), total iron‐binding capacity (P = 0.036), and phosphorus (P = 0.037). Multiple regression analysis showed that age (95% confidence interval [CI] ?0.008 to ?0.002), anxiety (95% CI ?0.025 to ?0.009), and support from friends (95% CI 0.004 to 0.018) were independent predictors of impaired HRQoL. This study explored determinants of impaired HRQoL in HD patients. We found that impaired HRQoL was independently associated with age, anxiety, and support from friends. We should consider psychosocial as well as clinical factors when evaluating ways to improve HRQoL in HD patients. 相似文献

Background: Among patients receiving chronic HD, therapy with paricalcitol (Z) was associated with reduced mortality and morbidity compared to treatment with calcitriol (C). Furthermore, patients who did not receive any vitamin D therapy experienced highest mortality and morbidity. This study examined the hypothesis of a relationship between the dose of Z and subsequent hospitalization, more specifically, that patients receiving lower doses of Z would have a higher risk of being hospitalized. Methods: We performed a retrospective cohort study of patients new to HD who received treatment with Z or C between Jan 1999 and Dec 2001 using Poisson regression models. The primary exposure variable was the average dose/day, examined as categorical data by quintiles, during a 3‐month and then 12‐month follow‐up period excluding the days in hospitals. This latter exclusion was made due to uncertainty of the treatment during the period of hospitalization. Additional covariates included vitamin‐D group (Z vs. C), age, gender, race, and diabetes status, serum albumin, alkaline phosphatase, calcium, phosphorus, and iPTH. Results: We first examined dose of Z and C over a 3‐month period and then hospitalizations over the ensuing year. We did not find a dose‐response relationship in these analyses – i.e., dose over the first three months of dialysis is not associated with increased or reduced risk of hospitalizations during the ensuing 12 months. We then examined average dose of Z or C over the entire year and risk for hospitalization during the same year. Compared to total doses, average doses (total dose over the entire year divided by number of dialysis sessions during the same year) are less prone to bias. Risk of hospitalizations according to dose (lowest dose, Quintile 1) of injectable vitamin D is shown in the table below:

Septicemia is a serious problem in hemodialysis patients because it can lead to life-threatening complications and a persistently elevated risk of death. Most analyses have not examined whether there are differences in mortality risk among the organisms that cause these episodes of septicemia. This study was a retrospective cohort analysis of first septicemia hospitalizations during the first year of hemodialysis. Time to death (both in-hospital and within 12 weeks post-discharge) was compared among the different septicemia-causing organisms based on discharge diagnoses in Medicare billing data from 1996 to 2001. The effect of various complications on mortality risk was also evaluated. There were 22,130 septicemia hospitalizations identified. The most common organism identified was Staphylococcus aureus (27%), with no other organism having an incidence >10%. The overall unadjusted death rate from admission through 12 weeks of follow-up was 34%. During the first hospitalization, the death rate was 14%, and during the 12-week period after the hospitalization it was 20%. In adjusted analyses, S. aureus was associated with a 20% higher risk of death both during the in-hospital period and the 12-week post-discharge period, when compared with all other specified organisms. Hospitalizations complicated by meningitis, stroke, or endocarditis were also associated with increased risk of mortality, independent of the organism causing septicemia. Septicemia hospitalizations are associated with a high mortality rate--both during the initial hospitalization and after discharge. Meningitis, stroke, and endocarditis represent particularly serious complications. Overall, septicemia hospitalizations (especially for S. aureus) are serious events, and patients would benefit from better treatment and prevention. 相似文献

Background: Hemodialysis (HD) access‐related infection is a major cause of morbidity and mortality in HD patients. We tested whether hypoalbuminemia is a risk factor for HD access infection and whether mortality of HD catheter infection is affected by removal of the infected catheter. Methods: We analyzed the records of 87 patients on chronic HD who were hospitalized for HD access‐related infection. We obtained data on age, sex, preinfection serum albumin level, comorbidities, complications, infecting organism, type of infection, mode of management, and mortality. We compared preinfection serum albumin levels in 79 patients with HD access infection with the serum albumin levels of 198 control patients on chronic HD without HD access infection admitted to the hospital during the same time for other reasons. In the HD catheter infection subgroup, we compared mortalities between patients treated with catheter removal plus antibiotics as the primary mode of management and those treated initially with antibiotics alone. Results: Preadmission serum albumin level was lower in the HD access infection group (2.4 ± 0.6 g/dL) than in the control group (3.2 ± 0.6 g/dL, P < 0.0001). Logistic regression identified preadmission serum albumin level as a strong independent predictor of HD access infection. In a logistic regression model, with age, sex, HIV status, diabetes, and type of HD vascular access (excluding arterovenous fistula) as the covariates, the odds ratio of HD access infection was 9.8 (95% confidence interval [CI] 4.9–19.7) for a serum albumin level ≤ 3.0 g/dL (P < 0.0001), 10.4 (95% CI 4.97–21.6) for a serum albumin level ≤ 2.5 g/dL (P < 0.0001), and 28.0 (95% CI 5.8–135.9) for a serum albumin level ≤ 2.0 g/dL (P < 0.0001). Case mortality was 25.0% (4/16) in patients with tunneled HD catheter infection initially treated with antibiotics alone and 2.8% (2/71) in those treated with catheter removal plus antibiotics at the time of presentation (P = 0.0096). Conclusion: Hypoalbuminemia is associated with increased risk of HD access infection. Treatment of HD access infection with antibiotics alone is associated with increased risk of death. 相似文献

The prevalence of coronary artery disease (CAD) is high in hemodialysis (HD) patients. The aim of the study was to assess the diagnostic and prognostic value of dipyridamole stress echocardiography (DSE) in nondiabetic HD patients without signs or symptoms of CAD. In 51 out of 158 evaluated HD patients (21 females, age 67 [33–85] years, HD duration 38 [9–271] months), resting echocardiography and DSE were performed. Exclusion criteria were known CAD, diabetes mellitus, and pulmonary and oncologic pathologies. Logistic regression analysis was carried out to identify predictors of abnormal DSE response, while Cox regression analysis was performed to determine variables associated with total and cardiovascular mortality, after 43.3 (11–60) months of follow‐up. Seven patients (14%) showed a positive response to DSE (DSE+). In 5/7, CAD was documented by angiography: All of them underwent coronary revascularization. DSE+ patients had significantly smaller body mass index than patients with a negative response (DSE‐): 21.7 ± 1.9 vs. 25.1 ± 3.4 kg/m2 (p = 0.018). During follow‐up, 16 (31%) patients died. Older age hazard ratio [HR = 1.07; confidence interval (CI) = 1.01–1.12; p = 0.02] and higher plasma phosphate levels (HR = 10.41; CI = 2.30–47.17; p < 0.01) were predictors of total mortality. Male gender (HR = 22.7; CI = 1.45–354.4; p = 0.03), older age (HR = 1.24; CI = 1.03–1.50; p = 0.02), longer HD duration (HR = 1.13; CI = 1.01–1.26; p = 0.04), and positive response to DSE (HR = 5.82; CI = 1.04–32.65; p = 0.04) were associated with cardiovascular mortality. Ten percent of asymptomatic HD patients had significant CAD, but timely diagnosis did not seem to improve their prognosis. Total survival was associated with age and higher levels of plasma phosphate, while male gender, older age, longer HD duration, and DSE+ were predictors of cardiovascular mortality. 相似文献

Health-related quality of life (HRQoL) and sleep quality (SQ) were impaired in patients with end-stage renal disease (ESRD). The impairment of both HRQoL and SQ and being in a depressive mood were found to be associated with increased morbidity and mortality in dialysis patients. We aimed to investigate the association between SQ, HRQoL, and depression, and to define independent predictors of SQ and depression in peritoneal dialysis (PD) and hemodialysis (HD) patients. Ninety HD patients (41 females, 49 males with mean age 50 ± 15.7 years) and 64 PD patients (27 females, 37 males with mean age 52.4 ± 15.3 years) receiving renal replacement therapy for at least 3 months were screened for the assessment of SQ, HRQoL, and depression in this cross-sectional study. A modified postsleep inventory, Short Form of Medical Outcomes Study (SF-36) and Beck depression inventory (BDI) were applied to all patients for evaluating SQ, HRQoL, and depression, respectively. HD and PD patients had similar total SQ scores. Physical and mental component scale of HRQoL were found to be significantly higher in HD patients (p < 0.001). PD patients were found to be much more in depressive mood when compared with HD patients (p < 0.001). Independent predictors of depression in patients were mental component scale of HRQoL, gender (being female), and dialysis modality (being PD patient). Physical component scale was also found to be an independent predictor of SQ. This study showed that despite similar SQ scores between two groups, HD patients had better HRQoL and less depression than PD patients. 相似文献

The aim of this cross-sectional study was to compare health-related quality of life (HRQOL) of Russian hemodialysis (HD) patients with the general population and international data, and to determine factors influencing HRQOL. One thousand forty-seven HD patients from 6 dialysis centers were studied (576 male, age 43.5 +/- 12.5 years, HD duration 55.0 +/- 47.2 months). Health-related quality of life was evaluated by SF-36. Self-appraisal Depression Scale (W. Zung), State-Trait Anxiety Inventory, and Level of Neurotic Asthenia Scale were used. Hemodialysis patients scored significantly lower than the general Russian population in the majority of SF-36 scales. The only exception was the Mental Health score, which was even better than the general population. The Mean physical component score (PCS) of HD patients was 36.9 +/- 9.7, and the mental component score was (MCS) 44.2 +/- 10.5. In multiple linear regression analysis, increasing age, HD duration, depression level and number of days of hospitalization in the past 6 months were significant independent predictors of low PCS along with a low level of serum albumin. Advancing age was also a predictive factor for low MCS along with increase of HD duration, depression level, trait anxiety, and level of asthenia. As far as we know, this is the first study to report on HRQOL of a large sample of Russian HD patients performed using SF-36. Compared with the general population, Russian HD patients had significantly lower scores on the majority of SF-36 scales, especially in the physical domain. The mean PCS and MCS were comparable with European data for HD patients. A number of demographic, clinical, and psychological variables affect HRQOL. 相似文献

Background: Rising hospital care costs have created pressure to shorten hospital stays and emphasize outpatient care. This study tests the hypothesis that shorter median length of stay (LOS) as a dialysis facility practice is associated with higher rates of early readmission. Methods: Readmission within 30 days of each hospitalization was evaluated for participants in the Dialysis Outcomes and Practice Patterns Study, an observational study of randomly selected hemodialysis patients in the United States (142 facilities, 5095 patients with hospitalizations), five European countries (101 facilities, 2281 patients with hospitalizations), and Japan (58 facilities, 883 patients with hospitalizations). Associations between median facility LOS (estimated from all hospitalizations at the facility and interpreted as a dialysis facility practice pattern) and odds of readmission were assessed using logistic regression, adjusted for patient characteristics and the LOS of each index hospitalization. Results: Risk of readmission was directly and significantly associated with LOS of the index hospitalization (adjusted odds ratio [AOR] 1.005 per day in median facility LOS, p = 0.007) and inversely associated with median facility LOS (AOR = 0.974 per day, p = 0.016). This latter association was strongest for US hemodialysis centers (AOR = 0.954 per day, p = 0.015). Conclusions: Dialysis facilities with shorter median hospital LOS for their patients have higher odds of readmission, particularly in the United States, where there is greater pressure to shorten LOS. The determinants and consequences of practices related to hospital LOS for hemodialysis patients should be further studied. 相似文献

Background: Hemodialysis (HD)‐related lower extremity (LE) muscle cramps are a common cause of morbidity in end‐stage renal disease patients on maintenance HD. Numerous pharmacologic and physical measures have been tried with variable success rates. Methods: Sequential compression devices (SCD) improve venous return (VR) and are commonly used to prevent LE deep venous thrombosis in hospitals. We hypothesized that LE cramps are triggered by stagnant venous flow during HD and are preventable by improving VR. We prospectively studied four adult patients (mean age 61 ± 14 years) on thrice‐weekly HD who experienced two or more episodes of LE cramping weekly in the month before the study. SCD were applied before each HD on both legs and compressions were intermittently applied at 40 mmHg during treatment. Results: All four patients reported complete resolution of cramping during the study period that lasted 1 month or 12 consecutive dialysis treatments. Conclusion: Application of SCD to LE may prevent the generation of LE HD‐related cramping in a select group of patients. Larger, controlled studies are needed to establish the utility of this noninvasive alternative for the prevention of LE HD‐related cramps. 相似文献

This study examined whether people born in other countries had higher rates of death and hospitalization due to road crashes than people born in Australia. Data on deaths that occurred in the whole of Australia between 1994 and 1997 and hospitalizations that occurred in the state of New South Wales, Australia, between 1 July 1995 and 30 June 1997 due to road crashes were analyzed. The rates of death and hospitalization, adjusted for age and area of residence, were calculated using population data from the 1996 Australian census. The study categorized people born in other countries according to the language (English speaking, non-English speaking) and the road convention (left-hand side, right-hand side) of their country of birth. Australia has the left-hand side driving convention. The study found that drivers born in other countries had rates of death or hospitalization due to road trauma equal to or below those of Australian born drivers. In contrast, pedestrians born in other countries, especially older pedestrians had higher rates of death and hospitalization due to road crashes. Pedestrians aged 60 years or more born in non-English speaking countries where traffic travels on the right-hand side of the road had risks about twice those of Australian born pedestrians in the same age group. 相似文献

Introduction: Central venous catheters (CVC) increase risks associated with hemodialysis (HD), but may be necessary until an arteriovenous fistula (AVF) or graft (AVG) is achieved. The impact of vascular imaging on achievement of working AVF and AVG has not been firmly established. Methods: Retrospective cohort of patients initiating HD with CVC in 2010–2011, classified by exposure to venography or Doppler vein mapping, and followed through December 31, 2012. Standard and time‐dependent Cox models were used to determine hazard ratios (HRs) of death, working AVF, and any AVF or AVG. Logistic regression was used to assess the association of preoperative imaging with successful AVF or AVG among 18,883 individuals who had surgery. Models were adjusted for clinical and demographic factors. Findings: Among 33,918 patients followed for a median of 404 days, 39.1% had imaging and 55.7% had surgery. Working AVF or AVG were achieved in 40.6%; 46.2% died. Compared to nonimaged patients, imaged patients were more likely to achieve working AVF (HR = 1.45 [95% confidence interval [CI] 1.36, 1.55], P < 0.001]), any AVF or AVG (HR = 1.63 [1.58, 1.69], P > 0.001), and less likely to die (HR = 0.88 [0.83‐0.94], P < 0.001). Among patients who had surgery, the odds ratio for any successful AVF or AVG was 1.09 (1.02–1.16, P = 0.008). Discussion: Fewer than half of patients who initiated HD with a CVC had vascular imaging. Imaged patients were more likely to have vascular surgery and had increased achievement of working AV fistulas and grafts. Outcomes of surgery were similar in patients who did and did not have imaging. 相似文献

An arteriovenous fistula (AVF) is the preferential hemodialysis (HD) access. The goal of this study was to identify factors associated with pre‐dialysis AVF failure in an elderly HD population. We used United States Renal Data System + Medicare claims data to identify patients ≥67 years old who had an AVF as their initial vascular access placed pre‐dialysis. Failure of the AVF to be used for initial HD, was used as the outcome. Logistic regression model was used to identify factors associated with AVF failure. The study cohort consisted of 20,360 subjects (76.2 ± 6.02 year old, 58.5% men). Forty‐eight percent of patients initiated dialysis using an AVF, while 52% used a catheter or an AVG. The following variables found to be associated with AVF failure when an AVF was created at least 4 months pre‐HD initiation: older age (odds ratio [OR] 1.01; 95% confidence interval [CI] 1.00–1.02), female gender (OR 1.69; 95% CI 1.55–1.83), black race (OR 1.41; 95% CI 1.26–1.58), history of diabetes (OR 1.22; 95% CI 1.06–1.39), cardiac failure (OR 1.26; 95% CI 1.15–1.37), and shorter duration of pre–end‐stage renal disease (ESRD) nephrology care (OR for a nephrology care of less than 6 months prior to ESRD of 1.22 compared with a pre‐ESRD nephrology follow up of more than 12 months; 95% CI 1.07–1.38). OR for AVF failure for the entire cohort showed similar findings. In an elderly HD population, there is an association of older age, female gender, black race, diabetes, cardiac failure and shorter pre‐ESRD nephrology care with predialysis AVF failure. 相似文献

We aimed to evaluate the long-term effect of hemodialysis (HD) treatment on left and right ventricular (LV and RV) functions in patients with end-stage renal disease. The study population consisted of 22 patients with newly diagnosed end-stage renal disease. Before an arteriovenous fistula was surgically created for HD, the patients were evaluated by echocardiography for systolic and diastolic functions. After the first HD session (mean 24.22 ± 2.14 months), the second echocardiographic evaluations were performed. Left ventricular and RV functions before and after long-term HD treatment were compared. The mean age was 55 ± 13 years and 10 (45%) of the patients were female. After long-term HD treatment, the isovolumic relaxation time was significantly decreased; however, the peak early (E) and late (A) diastolic mitral inflow velocities, E/A ratio, and deceleration time of E wave were not significantly different from the baseline measurements. Also, there was no significantly change in the early diastolic velocity (Ea) of the lateral mitral anulus and the E/Ea ratio. Pulmonary vein peak diastolic velocity, peak atrial reversal velocity, and peak atrial reversal velocity duration remained almost unchanged even though the pulmonary vein peak systolic velocity and the pulmonary vein peak systolic velocity/pulmonary vein peak diastolic velocity ratio were significantly lower after long-term HD treatment. In addition, LV systolic functions, LV diameters, LV mass index, left atrium size, and RV diastolic functions were not statistically different after long-term HD treatment. The myocardium is exposed to hemodynamic, metabolic, and neuro-humoral abnormalities during HD treatment; however, the long-term effects of HD on ventricular functions are not clearly known. The present study showed that the long-term effects of HD on LV and RV functions were insignificant in patients with end-stage renal disease. We have demonstrated that the LV and RV functions did not change significantly after long-term HD treatment. We suggest that this result may be due to regulated blood pressure levels of the patients, treatment of anemia and other metabolic disorders during the HD period and the prevention of weight gain and hypervolemia. 相似文献
