Eighty-two percent (82%) of patients initiating hemodialysis in the United States in 2006 did so with a catheter as the functioning access. Even in patients who have been followed by nephrologists for 6 months or more, 74% of patients initiated dialysis with a catheter. This is a multifactoral problem that requires attention and solutions from all stakeholders, including the nephrologist, the vascular surgeon, the hospital, and the insurance industry, as well as the patient and family. We propose a series of specific proposals that include a process for the timely referral and timely placement of a permanent access based on the patient's estimated or measured glomerular filtration rate (GFR), and a 'pay-for-performance' measure for vascular surgeons and nephrologists who admit patients with functional permanent accesses; such pay for performance would place a higher value for patients who are admitted with a functional arteriovenous (AV) fistula than for patients who are admitted with an AV graft. We also propose that hospitals develop a less permissive process for placement of PICC (peripherally inserted central catheters) lines in patients with GFR <60 ml/min and to consider surgery for access placement as 'urgent'. Finally, a more proactive educational process for patients and their families, including an 'informed non-consent' for patients who defer placement of a permanent access needs to be considered. The morbidity, mortality, and health-care costs associated with prolonged catheter use mandate urgent attention to this problem. [ABSTRACT FROM AUTHOR]

BACKGROUND: We hypothesized that a change from central venous catheters to a fistula or graft would improve short-term mortality risk in maintenance hemodialysis patients. DESIGN: Prospective observational study. SETTING & PARTICIPANTS: All maintenance in-center hemodialysis patients treated in Fresenius Medical Care, North America legacy facilities alive on January 1, 2007 with baseline laboratory data from December 2006. PREDICTOR: Access type (fistula, catheter, or graft), determined on December 31, 2006, and monthly thereafter. Conversion from a catheter to a fistula or graft during the 4-month period from January 1 to April 30, 2007. OUTCOME: Mortality was tracked from May 1, 2007, to December 31, 2007. Standard and time-dependent Cox models were used to determine hazard risks (HRs) of death with and without adjustment for case-mix and laboratory values. RESULTS: At baseline, 79,545 patients had 43% fistulas, 29% catheters, and 27% grafts. Mean age was 62 +/- 15 years, 54% were men, 51% were white, and 53% had diabetes. Compared with fistulas, unadjusted HRs of death were higher for grafts (1.22) and catheters (1.76; P < 0.001). In adjusted models, overall risk for grafts was decreased to 1.05 (95% limits, 1.003-1.100; P < 0.05) and approached that for fistulas consistently across multiple strata. Compared with patients who continued using a catheter, those who converted to either a graft or fistula had an HR of 0.69, whereas those who converted from a graft or fistula to a catheter had increased HRs to 2.12 (both P < 0.001). Similar trends were observed in the subset of incident patients (vintage < 90 days at study onset). LIMITATIONS: Observational design with residual confounding from unmeasured patient, facility, and treatment-related factors. CONCLUSIONS: Catheters have the worst associated mortality risk. Changing from a catheter to a fistula or graft is associated with significantly improved survival. The risk for grafts approached that of fistulas, providing an alternative to prolonged catheter exposure and potentially less hazardous 'bridge' toward a fistula. [ABSTRACT FROM AUTHOR]

BACKGROUND: We evaluated whether incremental achievement of up to 8 facility quality goals was associated with improvement in facility-specific mortality and hospitalization rates. STUDY DESIGN: Prospective observational study. SETTING & PARTICIPANTS: 1,085 Fresenius Medical Care, North America facilities providing hemodialysis (HD) for 25 or more patients during January 2006. MEASUREMENTS: The facility average for the period up to December 31, 2006, was used to determine achievement of each goal for equilibrated Kt/V, missed HD treatments, hemoglobin level, bicarbonate level, albumin level, phosphorus level, fistulae, and HD catheters. Linear regression models were used to relate facility-wide achievement of goals with facility-specific hospital days and standardized mortality ratios. RESULTS: Most facilities (64%) achieved 2 to 4 of 8 goals, with only 8% meeting more than 5 quality goals. Achieving more than 5 goals averaged 3.5 fewer hospital days/patient-year and 20% lower standardized mortality ratios (all P < 0.001). The incremental number of goals met also was associated with improvement in facility mortality (P < 0.001) and hospital days (P < 0.001). Catheter and albumin level goals were achieved least (6% and 9% of facilities, respectively), but they had the best outcomes. Facilities achieving more than 5 goals had older patients (64.0 versus 61.5 years; P < 0.001), fewer African American patients (16% versus 38%; P < 0.001), and fewer women (44% versus 46%; P = 0.003) compared with the average. LIMITATIONS: Observational design with residual confounding from unmeasured patient-, facility-, and treatment-related factors. CONCLUSIONS: Achieving more facility quality goals was significantly associated with better facility-based measurements of patient outcomes. Although these results do not establish a causal relationship, findings agree with the present practice of monitoring facility performance for continuous quality improvement.

BACKGROUND: To determine the most significant potentially actionable clinical variables associated with mortality and hospitalization risk in hemodialysis (HD) patients. STUDY DESIGN: Cohort study. SETTING & PARTICIPANTS: Adult maintenance HD patients in the Fresenius Medical Care, North America database as of January 1, 2004, with baseline information from October 1, 2003, to December 31, 2003, comprising approximately 26% of the US HD population. PREDICTORS: Case-mix (age, sex, race, diabetes, vintage, and body surface area), vascular access, and laboratory (albumin, equilibrated Kt/V, hemoglobin, calcium, phosphorus, creatinine, bicarbonate, biointact parathyroid hormone, transferrin saturation, and white blood cell count) variables. OUTCOMES: 1-year mortality and hospitalization risk from January 1 to December 31, 2004. MEASUREMENTS: Cox proportional hazards models for death and hospitalization. RESULTS: The cohort (N = 78,420) had a mean age of 61.4 +/- 15.0 years, 47% were women, 49% were white, 41% were black race (10% defined as 'other'), and 52% had diabetes. The top 5 actionable variables were the same for mortality and hospitalization. Final case-mix plus laboratory-adjusted hazard ratios for these top 5 actionable variables indicate 177% increased risk of death and 67% increased risk of hospitalization per 1-g/dL decrease in albumin level, 39% and 45% greater risk with catheters compared with fistulas, 18% and 9% greater risk per 1-mg/dL greater phosphorus level, 11% and 9% lower risk per 1-g/dL greater hemoglobin level, and 5% and 2% greater risk per 0.1-unit decrease in equilibrated Kt/V, respectively (all P < 0.0001). LIMITATIONS: Observational cross-sectional study with limited comorbidity adjustment (for diabetes). CONCLUSION: The same variables are associated with both mortality and hospitalization in HD patients. The top 5 potentially actionable variables are readily identifiable, with albumin level and catheter use the most prominent, and all 5 are appropriate targets for improvement. [ABSTRACT FROM AUTHOR]

BACKGROUND: Medicare data indicate that black hemodialysis patients receive greater doses of erythropoietin (EPO) than white patients when achieving similar hemoglobin levels. We confirmed and evaluated this observed association between race and EPO dose. STUDY DESIGN: Cross-sectional cohort study. SETTING & PARTICIPANTS: Primary Medicare-insured white (57%) and black (43%) adult long-term hemodialysis patients treated by Fresenius Medical Care who received EPO from January 1 to 31, 2004 (N = 44,721). PREDICTOR: White/black race. OUTCOMES: Average weekly EPO dose. MEASUREMENTS: Associations between race and baseline demographic and laboratory variables were evaluated by using logistic and linear regression models. Correlates of log-transformed weekly EPO dose were determined using linear regression models. RESULTS: Black patients received 12.6% more EPO than white patients (95% limits, 10.9% to 14.3%; P < 0.001). This racial difference in EPO dose was observed across similar hemoglobin levels despite fewer catheters (P < 0.001) and fewer prior hospitalization events in black patients (P = 0.002). Black patients were younger and had larger body size and greater albumin and biointact parathyroid hormone levels, but lower equilibrated Kt/V and white blood cell counts (all P < 0.001). In the 95th percentile of EPO dose (those receiving > 60,000 U/wk), there was a greater proportion of black patients (6% of total black population compared with only 4% in all white patients; P < 0.001). The difference in EPO dose between black and white patients was modified by age and was significant at ages younger than 45 and 65 years or older. LIMITATIONS: Observational study limited to white and black adult Medicare patients only, correlating with EPO doses from a single month, without adjustment for comorbid conditions. CONCLUSIONS: Black patients were administered approximately 12% greater EPO doses than white patients while achieving similar hemoglobin levels. We identified variables that differed across race that may explain this difference, but they were either not actionable or presented limited opportunity for intervention. Additional studies are needed to define a physiological (or pathological) basis for these observations. [ABSTRACT FROM AUTHOR]

The purpose of this nonrandomized, controlled pretestposttest study was to determine the effectiveness of a Fall Risk Reduction Program for community-dwelling older adults. The intervention group (n = 49) received three monthly educational sessions with a Tai Chi home exercise component and the comparison group (n = 31) viewed a video on fear of falling. Selected cognitive (Fall Facts Check-Off), affective (Activities-specific Balance Confidence Scale) and behavioral variables (Multidirectional Reach Test, Timed-Up-and-Go, 30 Second Chair Stand Test, and number of changes to reduce risks) were assessed. The intervention group demonstrated a significant increase in knowledge, had a variable adherence rate to exercise and made an average of 5.4 changes per person to reduce fall risks. There were no reports of initiating exercise or reducing fall risk factors from the comparison group. The Fall Risk Reduction Program is effective to increase fall-related knowledge and reduce fall risk factors in community-dwelling older adults. [ABSTRACT FROM AUTHOR]

The purpose of this multiple-subject case report is to describe the physical impairments, disabilities, and handicaps of patients with multiple traumas and pelvic-ring fractures after management with open reduction internal fixation. Nineteen men and 12 women, with a mean age of 38+/-16 years (mean+/-SD), were interviewed and examined at least 1 year (mean+/-14.5 months) after sustaining multiple traumas, including an unstable pelvic-ring fracture that was repaired by open reduction internal fixation. Disabilities and handicaps were assessed using the Oswestry Low Back Pain Questionnaire and the Sickness Impact Profile (SIP). Assessments of physical performance consisted of lift capacity, the amount of forward bending, and gait. A descriptive analysis by age and pelvic fracture classification is reported. The /= 50-year-old group had the lowest scores. Subjects with B1-class 'open-book' pelvic fractures had a tendency to score higher in individual SIP categories. The average SIP scores of 9.34 +/- 7.47 for the total SIP score, 7.79 +/- 6.93 for the physical dimension, and 8.24 +/- 9.61 for the psychosocial dimension represent mild disability. The mean Oswestry score of 13.26% +/- 15.41% also represents mild disability. Some subjects demonstrated impairments, disabilities, and handicaps 1 year postoperatively, but for the most part the subjects recovered almost all lost function. The data and clinical management information can be used as a basis of comparison for treatment and research with these types of patients. [ABSTRACT FROM AUTHOR]
