Service Utilization Patterns and Direct Medical Costs of Hospitalization in Patients With Renal Failure Before and After Initiating Home Peritoneal Dialysis.

OBJECTIVES: This study aimed to determine the hospital service utilization patterns and direct healthcare hospital costs before and during peritoneal dialysis (PD) at home. METHODS: A retrospective cohort study of patients with kidney failure (KF) was conducted at a Mexican Social Security Institute hospital for the year 2014. Cost categories included inpatient emergency room stays, inpatient services at internal medicine or surgery, and hospital PD. The study groups were (1) patients with KF before initiating home PD, (2) patients with less than 1 year of home PD (incident), and (3) patients with more than 1 year of home PD (prevalent). Costs were actualized to international dollars (Int$) 2023. RESULTS: We found that 53% of patients with KF used home PD services, 42% had not received any type of PD, and 5% had hospital dialysis while waiting for home PD. The estimated costs adjusting for age and sex were Int$5339 (95% CI 4680-9746) for patients without home PD, Int$17 556 (95% CI 15 314-19 789) for incident patients, and Int$7872 (95% CI 5994-9749) for prevalent patients; with significantly different averages for the 3 groups (P < .001). CONCLUSIONS: Although the use of services and cost is highest at the time of initiating PD, over time, using home PD leads to a significant reduction in use of hospital services, which translates into institutional cost savings. Our findings, especially considering the high rates of KF in Mexico, suggest a pressing need for interventions that can reduce healthcare costs at the beginning of renal replacement therapy.

Evaluating a remote patient monitoring program for automated peritoneal dialysis.

BACKGROUND: The benefits of automated peritoneal dialysis (APD) have been established, but patient adherence to treatment remains a concern. Remote patient monitoring (RPM) programs are a potential solution; however, the cost implications are not well established. This study modeled, from the payer perspective, expected net costs and clinical consequences of a novel RPM program in Colombia. METHODS: Amarkov model was used to project costs and clinical outcomes for APD patients with and without RPM. Clinical inputs were directly estimated from Renal Care Services data or taken from the literature. Dialysis costs were estimated from national fees. Inpatient costs were obtained from a recent Colombian study. The model projected overall direct costs and several clinical outcomes. Deterministic and probabilistic sensitivity analyses (DSA and PSA) were also conducted to characterize uncertainty in the results. RESULTS: The model projected that the implementation of an RPM program costing US$35 per month in a cohort of 100 APD patients over 1 year would save US$121,233. The model also projected 31 additional months free of complications, 27 fewer hospitalizations, 518 fewer hospitalization days, and 6 fewer peritonitis episodes. In the DSA, results were most sensitive to hospitalization rates and days of hospitalization, but cost savings were robust. The PSA found there was a 91% chance for the RPM program to be cost saving. CONCLUSION: The results of the model suggest that RPM is cost-effective in APD patients which should be verified by a rigorous prospective cost analysis.

Radiological Tenckhoff catheter insertion for peritoneal dialysis: A cost-effective approach.

INTRODUCTION: Radiological insertion of Tenckhoff catheters can be an alternative option for peritoneal dialysis access creation, as compared to surgical catheter insertion. This study will review the outcomes and complications of radiological Tenckhoff catheter insertion in a metropolitan renal service and compare costs between surgical and radiological insertion. METHODS: Data were collected prospectively for all patients who had a Tenckhoff catheter insertion for peritoneal dialysis (PD) under radiological guidance at our hospital from May 2014 to November 2016. The type of catheter used and complications, including peri-catheter leak, exit site infection and peritonitis were reviewed. Follow-up data were also collected at points 3, 6 and 12 months from catheter insertion. Costing data were obtained from Queensland Health Electronic Reporting System (QHERS) data, average staff salaries and consumable contract price lists. RESULTS: In the 30-month evaluation period, 70 catheters were inserted. Two patients had an unsuccessful procedure due to the presence of abdominal adhesions. Seven patients had an episode of peri-catheter leak, and four patients had an exit site infection following catheter insertion. Peritonitis was observed in nine patients during the study period. The majority of patients (90%) remained on peritoneal dialysis at 3-month follow-up. The average costs of surgical and radiological insertion were noted to be AUD$7788.34 and AUD$1597.35, respectively. CONCLUSION: Radiological Tenckhoff catheter insertion for peritoneal dialysis appears to be an attractive and cost-effective option given less waiting periods for the procedure, the relatively low cost of insertion and comparable rates of complications.

Analysis of economic impact between the modality of renal replacement therapy / Análise do impacto econômico entre as modalidades de terapia renal substitutiva

Abstract Introduction: Chronic kidney disease (CKD) is a major health problem, determining the reduction in life expectancy and an increased risk of cardiovascular disease. Method: An observational, cohort, retrospective, based on patient's medical records data with CKD under hemodialysis, peritoneal dialysis and kidney transplantation in the city of Curitiba, in the period from January to June 2014, evacuativo the financial impact on the Unified Health System (SUS) and the supplementary health. Results: The lowest cost of a kidney transplant in the first year was R$ 40,743.03 when cyclosporine was used and the highest was R$ 48,388.17 with the use of tacrolimus. In the second year post-transplant, hemodialysis and peritoneal dialysis have a higher cost compared to kidney transplant. Transplantation with deceased donor, treated with tacrolimus: R$ 67,023.39; Hemodialysis R$ 71,717.51 and automated peritoneal dialysis automatic R$ 69,527.03. Conclusions: After the first two years of renal replacement therapy, transplantation demonstrates lower costs to the system when compared to other modalities evaluated. Based on that, this therapy justifies improvements in government policies in this sector.

Health policies on dialysis modality selection: a nationwide population cohort study.

OBJECTIVES: In Taiwan, peritoneal dialysis (PD) and haemodialysis are fully accessible to patients with end-stage renal disease. However, the usage of PD is considered low in Taiwan. Since 2005, 4 major policies have been implemented by Taiwan's Ministry of Health and Welfare, namely a multidisciplinary predialysis care programme and usage increasing the PD incidence as a key performance indicator (KPI) for hospital accreditation, both of which were implemented in 2006; reimbursement of the glucose-free dialysate, icodextrin that was implemented in 2007; and insurance reimbursement for renting automated PD machines that was implemented in 2008. The aim of this study was to analyse the associations between the PD promotional policies and the actual PD selection rates. SETTING: We analysed data within the Taiwan Renal Registry Data System from 2006 to 2013, focusing on the PD incidence in relation to the timings of the 4 PD promotional policies; then we stratified the results according to age, sex and the presence of diabetes mellitus. PARTICIPANTS: From 2006 to 2013, 115 565 patients were enrolled in this study. The mean (SD) age of patients on PD was 54.6 (15.7) years. RESULTS: During the time frame in which the 4 PD promotional policies were implemented, the PD incidence increased from 12.8% in 2006 to 15.1% in 2009. The PD incidence started to decline in 2010 (13.8%) when the hospital accreditation policy was repealed. The 3 remaining policies were weakly associated with the PD incidence. The observational analysis determined that the patients' ages, sexes and diabetes mellitus incidence rates were relatively stable from 2006 to 2013. CONCLUSIONS: Of the 4 health policies intended to promote PD usage, using increasing the PD incidence as a KPI for hospital accreditation had the strongest association with the PD incidence.

Healthcare costs in chronic kidney disease and renal replacement therapy: a population-based cohort study in Sweden.

OBJECTIVE: To compare healthcare costs in chronic kidney disease (CKD) stage 4 or 5 not on dialysis (estimated glomerular filtration rate <30 mL/min/1.73m2), peritoneal dialysis, haemodialysis and in transplanted patients with matched general population comparators. DESIGN: Population-based cohort study. SETTING: Swedish national healthcare system. PARTICIPANTS: Prevalent adult patients with CKD 4 or 5 (n=1046, mean age 68 years), on peritoneal dialysis (n=101; 64 years), on haemodialysis (n=460; 65 years) and with renal transplants (n=825; 52 years) were identified in Stockholm County clinical quality registers for renal disease on 1 January 2010. 5 general population comparators from the same county were matched to each patient by age, sex and index year. PRIMARY AND SECONDARY OUTCOME MEASURES: Annual healthcare costs in 2009 incurred through inpatient and hospital-based outpatient care and dispensed prescription drugs ascertained from nationwide healthcare registers. Secondary outcomes were annual number of hospital days and outpatient care visits. RESULTS: Patients on haemodialysis had the highest mean annual cost (€87 600), which was 1.49 (95% CI 1.38 to 1.60) times that observed in peritoneal dialysis (€58 600). The mean annual cost was considerably lower in transplanted patients (€15 500) and in the CKD group (€9600). In patients on haemodialysis, outpatient care costs made up more than two-thirds (€62 500) of the total, while costs related to fluids ($29 900) was the largest cost component in patients on peritoneal dialysis (51%). Compared with their matched general population comparators, the mean annual cost (95% CI) in patients on haemodialysis, peritoneal dialysis, transplanted patients and patients with CKD was 45 (39 to 51), 29 (22 to 37), 11 (10 to 13) and 4.0 (3.6 to 4.5) times higher, respectively. CONCLUSIONS: The mean annual costs were ∼50% higher in patients on haemodialysis than in those on peritoneal dialysis. Compared with the general population, costs were substantially elevated in all groups, from 4-fold in patients with CKD to 11, 29 and 45 times higher in transplanted patients and patients on peritoneal dialysis and haemodialysis, respectively.

Understanding cost of care for patients on renal replacement therapy: looking beyond fixed tariffs.

BACKGROUND: In a number of countries, reimbursement to hospitals providing renal dialysis services is set according to a fixed tariff. While the cost of maintenance dialysis and transplant surgery are amenable to a system of fixed tariffs, patients with established renal failure commonly present with comorbid conditions that can lead to variations in the need for hospitalization beyond the provision of renal replacement therapy. METHODS: Patient-level cost data for incident renal replacement therapy patients in England were obtained as a result of linkage of the Hospital Episodes Statistics dataset to UK Renal Registry data. Regression models were developed to explore variations in hospital costs in relation to treatment modality, number of years on treatment and factors such as age and comorbidities. The final models were then used to predict annual costs for patients with different sets of characteristics. RESULTS: Excluding the cost of renal replacement therapy itself, inpatient costs generally decreased with number of years on treatment for haemodialysis and transplant patients, whereas costs for patients receiving peritoneal dialysis remained constant. Diabetes was associated with higher mean annual costs for all patients irrespective of treatment modality and hospital setting. Age did not have a consistent effect on costs. CONCLUSIONS: Combining predicted hospital costs with the fixed costs of renal replacement therapy showed that the total cost differential for a patient continuing on dialysis rather than receiving a transplant is considerable following the first year of renal replacement therapy, thus reinforcing the longer-term economic advantage of transplantation over dialysis for the health service.

The financial impact of increasing home-based high dose haemodialysis and peritoneal dialysis.

BACKGROUND: Evidence suggests that high dose haemodialysis (HD) may be associated with better health outcomes and even cost savings (if conducted at home) versus conventional in-centre HD (ICHD). Home-based regimens such as peritoneal dialysis (PD) are also associated with significant cost reductions and are more convenient for patients. However, the financial impact of increasing the use of high dose HD at home with an increased tariff is uncertain. A budget impact analysis was performed to investigate the financial impact of increasing the proportion of patients receiving home-based dialysis modalities from the perspective of the England National Health Service (NHS) payer. METHODS: A Markov model was constructed to investigate the 5 year budget impact of increasing the proportion of dialysis patients receiving home-based dialysis, including both high dose HD at home and PD, under the current reimbursement tariff and a hypothetically increased tariff for home HD (£575/week). Five scenarios were compared with the current England dialysis modality distribution (prevalent patients, 14.1% PD, 82.0% ICHD, 3.9% conventional home HD; incident patients, 22.9% PD, 77.1% ICHD) with all increases coming from the ICHD population. RESULTS: Under the current tariff of £456/week, increasing the proportion of dialysis patients receiving high dose HD at home resulted in a saving of £19.6 million. Conducting high dose HD at home under a hypothetical tariff of £575/week was associated with a budget increase (£19.9 million). The costs of high dose HD at home were totally offset by increasing the usage of PD to 20-25%, generating savings of £40.0 million - £94.5 million over 5 years under the increased tariff. Conversely, having all patients treated in-centre resulted in a £172.6 million increase in dialysis costs over 5 years. CONCLUSION: This analysis shows that performing high dose HD at home could allow the UK healthcare system to capture the clinical and humanistic benefits associated with this therapy while limiting the impact on the dialysis budget. Increasing the usage of PD to 20-25%, the levels observed in 2005-2008, will totally offset the additional costs and generate further savings.

Laparoscopic versus open peritoneal dialysis catheter insertion cost analysis.

BACKGROUND: Peritoneal dialysis (PD) is a cost-effective alternative to hemodialysis (HD). PD catheters have traditionally been inserted through a small open incision, but insertion using laparoscopic visualization has become increasingly popular and is associated with less catheter malfunction. The aim of this study was to compare costs of laparoscopic and open insertion strategies while taking into account postoperative complications and future salvage procedures. METHODS: A decision analysis model was constructed to simulate 1 y outcomes after PD catheter insertion by either the open or laparoscopic approach. Possible outcomes after PD catheter placement included functional catheter, infection, and catheter malfunction. Ultimately, patients continued with successful PD or switched to HD. Baseline probabilities, costs, and ranges were determined from a critical review of the literature. Sensitivity analyses were performed to determine the model strength over a range of clinically relevant probabilities. RESULTS: The total annual costs, including postoperative management and dialysis treatment, were $69,491 for laparoscopic insertion and $69,960 for open insertion. In case of a catheter malfunction, an initial attempt at salvage by fluoroscopy-guided wire manipulation cost less than a first attempt by laparoscopic repositioning. CONCLUSIONS: When accounting for a year of postoperative management and treatment, laparoscopic insertion can be less costly than open insertion in the hands of an experienced surgeon. Despite higher initial costs, PD catheter insertion under laparoscopic visualization can have lower total costs due to fewer postoperative complications. With increasing emphasis on cost-effective care, laparoscopic insertion is a valuable tool for initiating PD.

Structured outpatient peritoneal dialysis catheter insertion is safe and cost-saving.

BACKGROUND: Data about outcomes and costs for peritoneal catheter insertion on an outpatient basis are scarce. METHODS: Using patient files, all peritoneal dialysis (PD) catheter insertions performed between 2004 and 2009 in a single-center tertiary care institution for adult patients were located. Patient demographics, complications, hospitalizations, survival, and treatment modality changes were recorded. Procedure-related expenses were valued as actual production costs. RESULTS: During the study period, 106 PD catheters were inserted. In 46 cases, the patients were admitted electively for catheter insertion; 19 catheters were placed during admission for other medical reasons; and 41 catheters were placed on an outpatient basis. Among the study patients (54.7 ± 16.0 years of age), 45% were diabetic. Early (<30 days) catheter-related complications occurred in 22% of patients. The incidences of technique failure and any complication within 90 days were 10% and 38% respectively. The occurrence of complications was not statistically significantly different for outpatients and electively admitted patients. Average costs for catheter insertion were higher in electively hospitalized patients than in outpatients (€2320 ± €960 vs €1346 ± €208, p < 0.000). CONCLUSIONS: Compared with an inpatient procedure, outpatient insertion of a PD catheter results in similar outcomes at a lower cost.

Laparoscopic peritoneal dialysis catheter implantation with an intra-abdominal fixation technique: a report of 53 cases.

OBJECTIVE: The purpose of this study was to evaluate the feasibility, the safety, and outcomes of renal replacement therapy with the laparoscopic technique for peritoneal dialysis (PD) catheter implantation with an intra-abdominal fixation. METHODS: Medical records of 53 patients with end-stage renal disease who underwent laparoscopic PD catheter implantation with an intra-abdominal fixation in our department from December 2008 to October 2009 were reviewed retrospectively. Their surgical procedure, operative outcomes, postoperative complications, and follow-up outcomes were analyzed. RESULTS: All patients underwent laparoscopic PD catheter implantation with an intra-abdominal fixation successfully. Neither conversion to open surgery nor major intraoperative complications were observed. The median operative time was 24.2±10.5 minutes. The operative cost was 837.3±107.0 US$. Two patients (3.8%) had catheter obstruction peritonitis 12 and 15 months after surgery, respectively, and both of them had the catheter removed. CONCLUSIONS: Laparoscopic PD catheter implantation with an intra-abdominal fixation of the catheter tip is feasible and safe. It had a low incidence of PD catheter migration and other PD-related postoperative complications with the benefit of minimal invasiveness, a shorter operation time, and quicker postoperative recovery.

Comparison of cost-utility between automated peritoneal dialysis and continuous ambulatory peritoneal dialysis.

BACKGROUND AND AIMS: The use of automated peritoneal dialysis (APD) is increasing compared to continuous ambulatory peritoneal dialysis (CAPD). Surprisingly, little data about health benefits and cost of APD exist, and virtually no information comparing the cost-utility between CAPD and APD is available. We undertook this study to evaluate and compare the health-related quality of life (HRQOL) and cost-utility indexes in patients on CAPD vs. APD METHODS: This was a prospective cohort of patients initiating dialysis (2008-2009). Two questionnaires were self-administered: European Research Questionnaire Quality of Life (EQ-5D) and Kidney Disease Quality of Life (short form, KDQOL-SF, Rand, Santa Monica, CA). Direct medical costs (DMC) were determined from the health provider perspective including the following medical resource utilization: outpatient clinic/emergency care, dialysis procedures, medications, laboratory tests, hospitalization, and surgery. Cost-utility indexes were calculated dividing total mean cost by indicators of the HRQOL. RESULTS: One hundred twenty-three patients were evaluated: 77 on CAPD and 46 on APD. Results of the EQ-5D and KDQOL-SF questionnaires were significantly better in APD compared to the CAPD group. Main costs in both APD and CAPD were attributed to hospitalization and dialysis procedures followed by medication and surgery. Outpatient clinic visits and laboratory tests were significantly more costly in CAPD than in APD, whereas dialysis procedures were more expensive in the latter. Cost-utility indexes were significantly better in APD compared to CAPD. CONCLUSIONS: A significant cost-utility advantage of APD vs. CAPD was observed. The annual DMC per-patient were not different between groups but the HRQOL was better in the APD compared to the CAPD group.

Lifetime costs for peritoneal dialysis and hemodialysis in patients in Taiwan.

BACKGROUND: This study compared the lifetime costs for peritoneal dialysis (PD) and hemodialysis (HD) patients in Taiwan. METHODS: Using the National Health Insurance (NHI) database of all end-stage renal disease patients on maintenance dialysis registered from July 1997 to December 2005, we matched eligible PD patients with eligible HD patients on age, sex, and diabetes status. The matched patients were followed until 31 December 2006. Patients were excluded if they were less than 18 years of age, had been diagnosed with cancer before dialysis, or had been dialyzed at centers or clinics other than hospitals. Outcomes-including life expectancy, total lifetime costs, and costs per life-year paid by the NHI-were estimated and compared. RESULTS: The 3136 pairs of matched PD and HD patients had a mean age of 53.2 ± 15.4 years. The total lifetime cost for PD patients (US$139 360 ± US$8 336) was significantly lower than that for HD patients (US$185 235 ± US$9 623, p < 0.001). Except for patients with diabetes (who had a short life expectancy), the total lifetime cost was significantly lower for PD patients than for HD patients regardless of sex and age (p < 0.01). CONCLUSION: In Taiwan, the total lifetime costs paid by the NHI were lower for PD than for HD patients.

Cost analysis of hemodialysis and peritoneal dialysis access in incident dialysis patients.

BACKGROUND: Although several studies have demonstrated the economic advantages of peritoneal dialysis (PD) over hemodialysis (HD), few reports in the literature have compared the costs of HD and PD access. The aim of the present study was to compare the resources required to establish and maintain the dialysis access in patients who initiated HD with a tunneled cuffed catheter (TCC) or an arteriovenous fistula (AVF) and in patients who initiated PD. METHODS: We retrospectively analyzed the 152 chronic kidney disease patients who consecutively initiated dialysis treatment at our institution in 2008 (HD-AVF, n = 65; HD-CVC, n = 45; PD, n = 42). Detailed clinical and demographic information and data on access type were collected for all patients. A comprehensive measure of total dialysis access costs, including surgery, radiology, hospitalization for access complications, physician costs, and transportation costs was obtained at year 1 using an intention-to-treat approach. All resources used were valued using 2010 prices, and costs are reported in 2010 euros. RESULTS: Compared with the HD-AVF and HD-TCC modalities, PD was associated with a significantly lower risk of access-related interventions (adjusted rate ratios: 1.572 and 1.433 respectively; 95% confidence intervals: 1.253 to 1.891 and 1.069 to 1.797). The mean dialysis access-related costs per patient-year at risk were €1171.6 [median: €608.8; interquartile range (IQR): €563.1 - €936.7] for PD, €1555.2 (median: €783.9; IQR: €371.4 - €1571.7) for HD-AVF, and €4208.2 (median: €1252.4; IQR: €947.9 - €2983.5) for HD-TCC (p < 0.001). In multivariate analysis, total dialysis access costs were significantly higher for the HD-TCC modality than for either PD or HD-AVF (ß = -0.53; 95% CI: -1.03 to -0.02; and ß = -0.50; 95% CI: -0.96 to -0.04). CONCLUSIONS: Compared with patients initiating HD, those initiating PD required fewer resources to establish and maintain a dialysis access during the first year of treatment.

Early trends from the Study to Evaluate the Prospective Payment System Impact on Small Dialysis Organizations (STEPPS).

BACKGROUND: Launched in January 2011, the prospective payment system (PPS) for the US Medicare End-Stage Renal Disease Program bundled payment for services previously reimbursed independently. Small dialysis organizations may be particularly susceptible to the financial implications of the PPS. The ongoing Study to Evaluate the Prospective Payment System Impact on Small Dialysis Organizations (STEPPS) was designed to describe trends in care and outcomes over the period of PPS implementation. This report details early results between October 2010 and June 2011. STUDY DESIGN: Prospective observational cohort study of patients from a sample of 51 small dialysis organizations. SETTING & PARTICIPANTS: 1,873 adult hemodialysis and peritoneal dialysis patients. OUTCOMES: Secular trends in processes of care, anemia, metabolic bone disease management, and red blood cell transfusions. MEASUREMENTS: Facility-level data are collected quarterly. Patient characteristics were collected at enrollment and scheduled intervals thereafter. Clinical outcomes are collected on an ongoing basis. RESULTS: Over time, no significant changes were observed in patient to staff ratios. There was a temporal trend toward greater use of peritoneal dialysis (from 2.4% to 3.6%; P = 0.09). Use of cinacalcet, phosphate binders, and oral vitamin D increased; intravenous (IV) vitamin D use decreased (P for trend for all <0.001). Parathyroid hormone levels increased (from 273 to 324 pg/dL; P < 0.001). Erythropoiesis-stimulating agent doses decreased (P < 0.001 for IV epoetin alfa and IV darbepoetin alfa), particularly high doses. Mean hemoglobin levels decreased (P < 0.001), the percentage of patients with hemoglobin levels <10 g/dL increased (from 12.7% to 16.8%), and transfusion rates increased (from 14.3 to 19.6/100 person-years; P = 0.1). Changes in anemia management were more pronounced for African American patients. LIMITATIONS: Limited data were available for the prebundle period. Secular trends may be subject to the ecologic fallacy and are not causal in nature. CONCLUSIONS: In the period after PPS implementation, IV vitamin D use decreased, use of oral therapies for metabolic bone disease increased, erythropoiesis-stimulating agent use and hemoglobin levels decreased, and transfusion rates increased numerically.

Costs and added value of haemodialysis and peritoneal dialysis outsourcing agreements.

BACKGROUND: Despite the discrepancy in results from Spanish studies on the costs of dialysis, it is assumed that peritoneal dialysis (PD) is more efficient than haemodialysis (HD). OBJECTIVES: To analyse the costs and added value of HD and PD outsourcing agreements in Galicia, the medical transport for HD and the relationship between the cost of the agreement and the cost of consumables used in continuous ambulatory peritoneal dialysis (CAPD) with bicarbonate. METHODS: The cost of the outsourcing agreements and the staff was obtained from official publications. The cost of PD and medical transport were calculated using health service data for one month and extrapolating it to one year. The cost of CAPD consumables was provided by the suppliers. The added value was calculated from the investments generated for each agreement treating 40 patients. RESULTS: Expressed as patient/year, the mean costs for treatment were €21595 and €25664 in HD and PD, respectively. Medical transport varied between €3323 and €6338, while those of the CAPD agreement and consumables were €19268 and €12057, respectively. The added value was greater with the HD agreement, especially considering the jobs created. CONCLUSIONS: One cannot generalise that the cost of PD, which is significantly influenced by prescriptions, is lower than that of HD. It would be appropriate to review the additional cost to consumables in the CAPD agreement. The added value generated by dialysis agreements should be considered in future studies and in health planning. More controlled studies are needed to better understand this issue.

Determinantes dos gastos com diálises no sistema único de saúde, Brasil, 2000 a 2004 / Determinants of expenditures on dialysis in the unified national health system, Brazil, 2000 to 2004

The aim of this study was to compare total outpatient expenditures on hemodialysis and peritoneal dialysis from 2000 to 2004 in patients that began dialysis in 2000 under the Unified National Health System (SUS). A historical cohort was developed, consisting of patients that began dialysis in 2000, identified by probabilistic matching in the database of Authorizations for High-Complexity/High-Cost Procedures (APAC). A multiple linear regression model was used, including individual and clinical attributes and health services supply variables. The cohort included 10,899 patients, 88.5 percent of whom began hemodialysis and 11.5 percent peritoneal dialysis. The dialysis modality explains 12 percent of the variance in expenditures, and patients in peritoneal dialysis showed 20 percent higher mean annual expenditure. The differences in expenditures are explained according to the State of Brazil and health services supply level. Individual risk variables did not alter the model's explanatory power, while age and diabetes mellitus were significant. The study showed the importance of the National Health System's payment mechanism for explaining differences in expenditures on dialysis treatment in Brazil.

O objetivo deste estudo é comparar os gastos ambulatoriais totais entre hemodiálise e diálise peritoneal, de 2000 a 2004, dos pacientes que iniciaram diálise, em 2000, no Sistema Único de Saúde (SUS). Foi desenvolvida coorte histórica de pacientes que iniciaram diálise em 2000, identificados por pareamento probabilístico na base de dados de Autorização de Procedimentos de Alta Complexidade/Custo (APAC). Utilizou-se modelo de regressão linear múltipla incluindo atributos individuais, clínicos e variáveis de oferta de serviços de saúde. A coorte foi constituída por 10.899 pacientes, 88,5 por cento iniciaram em hemodiálise, e 11,5 por cento, em diálise peritoneal. A modalidade explica 12 por cento da variância dos gastos, os pacientes em diálise peritoneal apresentam um gasto médio anual 20 por cento maior. Os diferenciais nos gastos são explicados pelo estado da federação e nível de oferta de serviços de saúde. As variáveis de risco individual não alteram o poder de explicação do modelo, sendo significativos a idade e a presença de diabetes mellitus. Constata-se a importância do sistema de pagamento do SUS para explicar as diferenças de gastos do tratamento dialítico no Brasil.
