Medication-Related Problems (MRP)in Dialysis Patients
• Probability is high– Average no. of drugs per day: 10-12– Complex comorbidity
• Several published papers on topic
• Pooled analysis was done
• MRPs were placed into 9 categories
• 1593 MRPs were identified in 395 patients

![Page 6: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/6.jpg)
Most Common MRPs
• Inappropriate laboratory monitoring (23.5%)
• Indication without drug therapy (16.9%)
• Dosing errors accounted for 20.4% of medication-related problems– Subtherapeutic dosage: 11.2%– Overdosage: 9.2%

Reduce MRPs and Improve Patient Outcomes and QOL
• Pharmacists uniquely trained to detect and manage MPRs
• All U.S. trained pharmacists graduate with 6+ years of training and a Pharm.D. degree
![Page 8: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/8.jpg)
Question
Under Medicare, which of the following health care professionals is not considered to be “part of the team” in the care of end-stage renal disease patients?
a. Nephrologistb. Social Workerc. Dieticiand. Nursee. Pharmacist
![Page 9: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/9.jpg)
Pharmacist as a CKD Team Member
• Pharmacists are not officially listed as an essential team member under the Medicare ESRD Conditions of Coverage
• About 65% of Canadian nephrology practices have access to a pharmacist and multidisciplinary care is encouraged
• In U.S., CKD care is more fragmented
Mendelssohn DC et al. Am J Kidney Dis 2006;47:277-284.
![Page 10: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/10.jpg)
Can Collaborative Team Care in CKD Patients Make a
Difference?
![Page 11: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/11.jpg)
Collaborative Multidisciplinary Clinic (MDC) Care
• Canadian CKD clinic models have been well-described in literature
• The Team: physician, nurse educator, pharmacist, social worker, nutritionist
• Standardized philosophy– Regular clinic visits with prespecified
education topics and management protocols– Frequency of visits, lab tests based on GFR
Levin A, et al. Am J Kidney Dis 1997;29:533-540.Curtis BM, et al. Nephrol Dial Transplant 2005;20:147-154.
![Page 12: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/12.jpg)
Short-term Outcomes Better with Collaborative MDC care
• Higher – GFR– Hb (10.2 ± 1.8 vs 9.0 ± 1.4)– Albumin– Calcium
• Similar– Phosphorus
Curtis BM, et al. Nephrol Dial Transplant 2005;20:147-154.
![Page 13: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/13.jpg)
Long-term Outcomes Better with Collaborative MDC
Curtis BM, et al. Nephrol Dial Transplant 2005;20:147-154.

Why Is Collaborative Care Beneficial?
• Nephrologist workforce shortages restrict care delivery to growing number of CKD patients
• Need for dietary counseling, improved medication management, medication adherence in CKD patients
• Many of these tasks can be more efficiently and effectively implemented by nurses, dieticians, social workers and pharmacists
• Each team member brings strengths that enhance patient care and outcomes
• Allows for provision of complex care

Avoiding Medication-Related Disasters…
During a Disaster

Lessons from Katrina
• Unlabeled medications confiscated at Superdome
• Refill policies of Medicaid, commerical insurers, Medicare Part D do not allow extra refills to allow for emergency supply
• Poor patient recall on medication list and doses

Medicare Part D and
Implications for ESRD Patients
![Page 22: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/22.jpg)
Medicare pays for treatment of end-stage renal disease (ESRD)
• Most patients who develop ESRD are eligible for Medicare benefits– Dialysis– Kidney transplantation
• Medicare coverage generally starts the fourth month after ESRD is determined– Exception: Patients who receive training for
home dialysis are eligible for Medicare benefits at the start of ESRD
![Page 23: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/23.jpg)
Medicare pays for treatment of end-stage renal disease (ESRD)
• If ESRD patient is covered by an employer group health plan (EGHP) – EGHP will be primary payer for total of 33
months from start of ESRD– Medicare coverage will start in the fourth month
as secondary payer– Coordination period lasts for 30 months– Then, Medicare becomes the primary payer,
EGHP becomes secondary payer
![Page 24: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/24.jpg)
Kidney Transplants and Medicare
• Medicare coverage can start the month patient is admitted to a Medicare-approved hospital for a kidney transplant
• Medicare coverage lasts for 36 months after a successful transplant; but after 36 months…– In general, no more Medicare benefits– EGHP, other health plans, Medicaid or other
assistance programs need to cover costs
![Page 25: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/25.jpg)
Medicare Prescription Drug Coverage
• Began January 1, 2006• Available for all people with Medicare
– Part A, Part B, or both• ~86% (279,350) dialysis and 58%
(74,315) transplant patients receive Medicare benefits
• >353,000 ESRD (dialysis + transplant) patients were eligible for Part D coverage in 2006
![Page 26: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/26.jpg)
Prescription Coverage Comparison:
With ESRD versus Without ESRD
Patel D. J Am Soc Nephrol 17: 2546–2553, 2006.
*table excludes patients dually eligible for Medicare and Medicaid
![Page 27: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/27.jpg)
ESRD Patients and Part D• Most dialysis patients can not join a Medicare
Advantage Part D plan (MAPD), only a stand-alone Prescription Drug Plan (PDP)
• “Successful” kidney transplant patients can join MAPD or PDP
• It is not clear just how many dialysis or kidney transplant patients have signed up for Part D
• It is clear that there have been significant issues for those that have signed up
![Page 28: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/28.jpg)
• After patient pay $265 yearly deductible, they pay– 25% of the yearly costs for covered drugs from
$265 to $2,400. Part D pays 75%.– 100% of costs for covered drugs from $2401 to
$5,451.25. i.e. they pay up to $3,850 in out-of-pocket costs (Doughnut Hole or gap)
– 5% of the costs for covered drugs (or a co-payment of $2 or $5), whichever is more, for the remainder of the calendar year (Catastrophic Coverage)
How Medicare Part D Standard Plan Works in 2007
![Page 29: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/29.jpg)
Medicare Part D Covered Drugs
Must cover “all or substantially all”• Cancer medicines• HIV/AIDS drugs• Anti-depressants• Anti-psychotics• Anti-convulsants• Immunosuppressants (unless covered by Part B)
Note: May not cover every brand name or all doses
![Page 30: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/30.jpg)
Standard Part D Excluded Drugs
• Anorexia, weight loss, weight gain• Fertility drugs• Cosmetic purposes, like hair growth• Cold and cough medicines• Non-prescription or over-the-counter (OTC)• Barbiturates (e.g. Seconal®, Nembutal®)• Benzodiazepines (e.g. Restoril®, Ativan®)• Vitamins and minerals
– Except prenatal vitamins, fluoride preparations and,– Oral active Vit D: Zemplar, Hectorol, Rocaltrol are
covered
Note: “Enhanced” plans may cover excluded drugs

Issues with Dual Eligible ESRD Patients
• Automatically enrolled in Medicare Part D Plans
• Some kidney-specific medications that were covered by state Medicaid programs in the past, were not covered by various Part D plans
• Some patients have unintentionally enrolled in plans with premiums
• Co-payment amounts often more than what these patients paid through state Medicaid programs
![Page 33: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/33.jpg)
Question
Assuming a dialysis patient is covered by Medicare Part A or B, then Part D will primarily pay for erythropoietin-stimulating agents (ESAs).
a. True
b. False
![Page 34: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/34.jpg)
b. False, is correct answer
![Page 35: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/35.jpg)
Part B versus Part DDialysis Issues
• Part B covers separately reimbursable medications given during or at dialysis session– Erythropoietin stimulating agents (ESAs)– IV active vitamin D agents (calcitriol,
paricalcitol, doxercalciferol)– IV iron products (iron sucrose, ferric gluconate,
iron dextran)– IV antibiotics
![Page 36: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/36.jpg)
Part B versus Part DDialysis Issues (continued)
• Part D will cover most oral medications• Part D will not cover
– Kidney-related vitamins (Nephrocap, Nephrovite, etc…)
– Benzodiazepines (anxiety, restless leg syndrome)
![Page 37: Preventing and Resolving Medication-related Problems in Individuals on Dialysis Wendy L. St. Peter, Pharm.D., FCCP, BCPS Associate Professor, College of.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551aa591550346761a8b62c4/html5/thumbnails/37.jpg)
Part B versus Part DKidney Transplant Issues
• If patient has a “Medicare-covered transplant” (MCT)– Immunosuppressants are covered under Part B for at least
36 months– After 36 months Part B will continue to pay if patient is
eligible for continued Medicare coverage (age or disability)• If patient did not have a “MCT”, but becomes eligible
for Medicare, then immunosuppressants covered under Part D
• Part D formularies are required to have “Substantially all” immunosuppressants

Consequences of “Tier Elevation”
• Patients “stretch out” their doses– Possible consequence: Transplant rejection
• Wasted nephrologist, social worker time dealing with barriers– Prior authorization– Step-therapy– Quantity limits
• Patient assistant programs during “gap”– Not much help available for those that have
some income or assets

More Dialysis-Specific Issues
• Many commonly used dialysis-related drugs are $$
• How many Part D medications are dialysis patients taking?
• What % of dialysis patients will reach Part D “doughnut hole”
• What % of patients will reach “catastrophic coverage”
