The first DRG: lessons from the end stage renal disease program for the prospective payment system
Summary
Medicare's early prospective payment system for end-stage renal disease (ESRD) encouraged cost savings but failed to fully benefit the government due to unadjusted prices. Lessons learned from ESRD reimbursement inform hospital payment strategies.
Area of Science:
- Health economics
- Healthcare policy
- Medical reimbursement systems
Background:
- Medicare implemented Diagnosis Related Groups (DRG) for hospital reimbursement in 1983.
- A decade of prior experience with prospective payment existed for the End-Stage Renal Disease (ESRD) program.
Purpose of the Study:
- To review Medicare's ESRD prospective payment experience.
- To identify lessons applicable to Medicare's hospital services reimbursement.
Main Methods:
- Review of Medicare's historical reimbursement data and program outcomes for ESRD.
- Analysis of the impact of fixed-price reimbursement on provider behavior and cost-saving initiatives.
Main Results:
- Prospective payment for renal dialysis incentivized cost-saving techniques by providers.
- Failure to adjust dialysis prices in line with cost reductions limited government savings.
- Independent changes in medical practice also influenced program outcomes.
Conclusions:
- Prospective payment systems can drive efficiency but require price adjustments to maximize benefits.
- Lessons from ESRD reimbursement are relevant for understanding the impact of DRG-based hospital payments.
- External factors, such as medical practice evolution, significantly affect prospective payment system outcomes.

01:25Drug Dosing in Renal Diseases: Measurement of Glomerular Filtration Rate
The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...
01:28Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration
Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area. This equation is...
01:30Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis
Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...
01:28Kidney Transplant I: Introduction
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
01:25Chronic Kidney Disease I: Introduction
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...
01:28Chronic Kidney Disease III: Interprofessional Care
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
