Peritoneal dialysis reduces the use of non native fistula access in dialysis programs.

Access problems remain the major difficulty associated with chronic hemodialysis. Despite recent recommendations by the Dialysis Outcomes Quality Initiative (DOQI) that native arteriovenous (AV) fistulae are the optimal form of vascular access, grafts and central catheters are used by many patients. We analyzed our large Canadian regional dialysis program, which has a high prevalence of peritoneal dialysis, to examine the effect of dialysis modality choice on vascular access utilization. Point prevalence data were collected from our program in October 1997, and technique and patient survival data for the period 1990-1996 were analyzed and compared to data for the remainder of Canada from the Canadian Organ Replacement Register. Mortality rate ratios were estimated using a Poisson regression model to correct for comorbidity, age, and end-stage renal disease etiology. Of 141 in-center hemodialysis patients, 91 had an AV fistula, 1 had a polytetrafluoroethylene (PTFE) graft, and 49 were catheter-dependent. The program also included 20 home hemodialysis patients with AV fistulae, and 156 patients on peritoneal dialysis. No mortality risk differences between hemodialysis and peritoneal dialysis are seen in our center, nor are they seen for each modality in comparison with the remainder of Canada. Technique survival for peritoneal dialysis at our center was about 80% at 2 years, significantly greater than for Canada. For the program as a whole, 49% of patients used peritoneal dialysis 35% a native AV fistula, and 15% a central catheter. For Canada and the U.S.A. respectively, the comparable data were: peritoneal dialysis, 32% and 17%; native fistula, 33% and 15%; PTFE, 19% and 41%; and central catheter 16% and 27%. These data suggest that the use of peritoneal dialysis may allow reduced use of non native AV fistula access without mortality penalty.

Adverse selection and price sensitivity when low-income people have subsidies to purchase health insurance in the private market.

Policymakers interested in subsidizing low-income people's purchase of private insurance face two major questions: will such subsidies lead to adverse selection, and how large do the subsidies have to be to induce large numbers of eligible people to purchase the insurance? This study examines New Jersey's short-lived experience with a premium subsidy program, Health Access New Jersey (Access Program). The program was for people in families with incomes below 250% of the poverty level who were not eligible for health insurance provided by an employer, or Medicaid or Medicare, and who wished to purchase policies in the state's individual health insurance market, the Individual Health Coverage Program. Surveying a random sample of Access Program policyholders, we compared their demographic and socioeconomic characteristics, as well as their health status, to those of other New Jersey residents who had family incomes below 250% of the poverty level to determine whether there was any evidence of adverse selection among the people who enrolled in the Access Program. The people who enrolled were not in worse health than uninsured people with incomes below 250% of the poverty level, but they were quite price sensitive. Most enrollees had incomes within the low end of the income eligibility distribution, reflecting the structure of rapidly declining subsidies as income increased.

Differential access to care for children with ADHD in special education programs.

Access to treatment for children with attention-deficit hyperactivity disorder (ADHD) was examined in the general health, specialty mental health, and informal care sectors. Special education students in a Florida school district were screened for ADHD, and high-risk children and their parents completed diagnostic and services assessment interviews. Female gender, minority status, and rural residence lowered the probability of ADHD service use in the general health sector. Use of services in the mental health and informal sectors was predicted by a child's need for services. Further study is needed to identify barriers to service use at the parental or gatekeeper level for this common disorder among children.
