BC Experience with Assisted PD: 12 month pilot results, evaluation implications and future directions
Assisted Peritoneal Dialysis: A Patient-Centered Approach to Support Self Management Dr. Micheli Bevilacqua, MD, FCRPC Quality Forum 2017 BC Provincial Renal Agency
Outline
• Background of the PD Assist (PDA) pilot project
• Review outcomes of the 12-month PDA pilot
• Discuss tips to contextualize outcomes of a patient-centred chronic disease support program
Disclosures
• Evaluation of PD Assist is one of several projects I am involved in with at BC Renal Agency for which I am paid a salary unrelated to the outcomes of PD Assist (or any other project)
• I have no other relevant financial or non-financial interests to disclose
Acknowledgments • PD patients advocating for and willing to be involved in this
new program
• PD units in the pilot areas
• Those involved in planning and evaluation of PD assist: Paul Taylor, Linda Turnbull, Sue Saunders, Penny Hill, Lee Er, Erlyn Amano, Suneet Singh and anyone else I may have left out!
Thanks to BC Patient Safety and Quality Council for recognizing our program!!
Background • Peritoneal dialysis (PD) is a treatment
modality for ESRD
• Compared to other treatment choices, there are some superior clinical outcomes, improved quality of life and cost savings
• PD is a home based therapy; patients themselves or family members/caregivers perform treatment independently
Background
• There were previously no supports available to assist patients/families who were struggling with self-care PD
• Benefits of PD are especially important for those most likely to struggle: • Avoiding transport, minimal disruption to daily routine,
independence, especially at end of life
• Supporting independence in these patients is patient-centered,
equitable and may increase overall penetrance of PD
Assisted PD Experience in other jurisdictions
• Europe: France, Germany, Denmark –all with decades of experience
• Canada: Ontario has several programs with varying levels of support • All have found ways to support PD patients • All come at increased cost • Reported outcomes of these programs are variable
PD Assist in BC Details of 12 month PDA pilot
• CCPD patients were identified as ‘at risk’ and in need of support by their PD team. Key areas that were targeted were: • Patient inability/fatigue with setup/dismantling of cycler machine • Care-giver burden related these tasks
• Standardized identification criteria were developed
• Enrolment could be either long-term or temporary (respite)
• Four PD sites in the Lower Mainland were chosen as the pilot centres: St Paul’s Hospital, Vancouver General Hospital, Royal Columbian Hospital and Abbotsford Regional Hospital
PD Assist in BC Details of 12 month PDA pilot
• The program uses a once daily visit by trained care givers to assist individuals in setup/dismantle of CCPD
• Patients/care-givers responsible for other CCPD related tasks • Troubleshooting, choosing dialysate, etc.
• The caregivers are provided by an external health service provider (Nurse Next
Door, NND) at no cost to patients
• NND care providers were trained and had competency assessed by our PD staff
• PDA only provides assistance in CCPD related tasks, not other aspects of care that the patients may need/request (unless privately arranged)
Who are we talking about?
• A 38 year old type 1 diabetic on PD who lives independently and broke his leg
• A 88 year old lady on PD for 6 years with progressive dementia relying entirely on husband to stay out of nursing home and do all the PD • Right now if he couldn’t manage or she needed placement,
she would transition to hemodialysis (costlier, associated with lower QoL)
Results of the 12 month pilot evaluation Temporary (Respite) PDA
Usage and outcomes of PDA respite program
• 1 transferred to HD – would have transferred regardless • 1 death on PD at home then hospice – this was the desired outcome • The other 7/9 returned to PD at home and avoided long admissions

Dialysis costs
The cost of the median duration of PD respite (29 days) is $1250 or approx. 1 day in hospital!
Summary of PDA Respite
• PDA Respite is an effective method to support patients temporarily unable to perform self care PD
• The vast majority of PDA respite patients returned to self care PD and avoided long hospital stay • Contrast to historical experience where patients remain hospitalized or are
transitioned to HD
• Median duration of respite was 29 days
• PDA respite is cost effective compared to alternatives
Results of the 12 month pilot evaluation Long-term PDA
Long-term PDA usage
• The enrollment period for long term PDA was July 18, 2014 to Mar 9, 2015
• A survey with standardized criteria to identify potential PDA patients was sent to all PD units
• 53 patients from the pilot centres ultimately enrolled in long term PDA
Comparator groups
To evaluate long term PDA, two comparator cohorts were used:
A benchmark PD cohort: All prevalent CCPD patients in BC between July 18 2014 and March 27 2015. A comparable ‘PDA Eligible’ cohort: Based on PD Assist eligibility survey, those who were deemed eligible for PD Assist service but were not on the service
PDA clinical outcomes: technique survival

Putting it all together Contextualizing results of PDA
Abraham Wald Operational problems versus general statistical problems
Patient-centered outcomes in chronic disease management
Patient-centered outcomes in chronic disease management
Technique survival • Equivalent technique survival is an excellent outcome • Goal is not to turn these patients into ‘well’ PD patients
Deaths on PDA
• This is a good outcome – a supported death at home, without a disruptive modality change
Hospitalization • This likely represents recognition of serious issues: seen in other trials and
anecdotally by our PD units
Patient feedback
Qualitative feedback was collected from patients, PD units and caregivers (NND). Feedback was overwhelmingly positive and supported continuation and expansion of PDA
– "We [My family and I] hope the program continues and I hope that more people get to participate in it…I think it's keeping people out of hospitals and allowing them to stay in their homes longer. Keeping them out of nursing homes and allowing them to stay in their homes longer.“
– “A blessing for many to know that they had an option to help support their family. Definitely helps to relieve the stress and potential burn out for many”
Costs of PDA
• A chronic disease management program such as PDA is best viewed through a cost minimization lens • ESRD patients who wish to have RRT do not have a zero cost option • Goal is to provide care that produces best outcomes at lowest cost
• PDA should be compared to other options for patients failing independent PD, not to self-care PD • Traditionally, these are LTC or HD
PDA ~ $15000 per year LTC ~ $38500 per year Transition to HD is ~ $44000 per year more than PD
Putting it all together
• PDA provides a patient-centered way to support patients on independent modality
• Clinical outcomes are acceptable, especially when viewed in the context of the frail population this program serves
• Costs are acceptable and lower than available alternatives
• Experience among patients, caregivers and PD units in pilot was very positive
Next steps
• The plan has been presented to PHSA leadership, all of whom support the PDA program
• They are highlighting it internally as a model of patient-centered chronic disease management
• PDA has the support of BC Provincial Renal Agency and dedicated funding from PHSA
– A provincial implementation plan is underway
