A Cost Analysis for the Implementation of a Dementia Patient and Carer Public Advisory Board for Health Research
This paper presents a four-year cost analysis of a dementia patient and carer Public Advisory Board, revealing that while PPI is resource-intensive with design and implementation as the primary cost drivers, early and deep community engagement ultimately enhances financial efficiency and ensures meaningful participation.

Imagine you're trying to build a super-cool, high-tech treehouse, but instead of just using wood and nails, you need to invite the people who will actually live in the treehouse to help design it, build it, and check if it's safe. That's what this research team did, but with a "Patient and Public Advisory Board" for dementia research. They wanted to figure out exactly how much time and money it takes to run this kind of team, because everyone keeps saying, "We want to do this, but it costs too much!"
Here's the scoop on what they found, served up with a few metaphors to keep things interesting.
The Big Reveal: It's Not the Guests, It's the Staff
The team spent four years tracking every single penny and hour spent on their advisory board. They found the total cost for one year of running the board was AUD $150,229.
Now, here is the twist that surprised everyone. Most people assume the biggest cost is paying the patients and carers (the "guests") for their time. But the paper rules out that idea. In fact, the paper argues that paying the board members is actually the smallest part of the bill.
Think of it like hosting a massive dinner party. You might think the cost is the fancy food you serve the guests. But this study found that the real cost is the army of chefs, waiters, and decorators (the researchers and staff) running around in the kitchen preparing the meal, setting the tables, and making sure everything runs smoothly.
- The Guests (Board Members): They only accounted for 5% of the total time spent and 12% of the total money spent.
- The Staff (Researchers): The senior researchers (the "Head Researchers" and "Advisors") ate up 36% of the time and 39% of the money. They were the ones doing the heavy lifting, especially in the beginning.
The Four Stages of the Party
The researchers broke the project down into four stages, like the chapters of a storybook. Here is where the money went:
- Design (The Blueprint Phase): This was the most expensive part, costing 43% of the total budget (AUD $64,080). This is where the Head Researchers spent 67% of their time drawing up the plans, writing the grant applications, and figuring out the rules. It's like spending months designing the treehouse before you even buy a single nail.
- Implementation (The Setup Phase): This cost 21% (AUD $31,158). This is when they started recruiting the board members. The biggest chunk of this cost went to finding and interviewing the right people.
- Operation (The Living Phase): This is where the actual meetings happen. Surprisingly, this only cost 19% (AUD $28,762). Even though this is where the board members are most active, the senior researchers stepped back, and junior staff (like Research Assistants) took over most of the work.
- Evaluation (The Review Phase): This cost 17% (AUD $26,228). This is when they looked back to see if the treehouse was actually safe and useful.
The "Hidden" Cost of Support
The paper suggests that a lot of the cost is "hidden." It's not just the time spent in the meeting room; it's all the time spent before and after the meeting.
- The Analogy: Imagine a board member shows up to a meeting. The paper says that for every hour the board member spends talking, the researchers spend hours preparing the agenda, reading documents, managing the website, and handling the finances.
- The Reality: The paper explicitly states that for every hour of public member time, there are significant support-related staff expenses. They argue that if you cut these support costs to save money, you risk the whole thing becoming a "token" gesture—like inviting someone to a party but never letting them speak.
What the Paper Says You Should (and Shouldn't) Do
The authors are pretty sure about a few things based on their numbers:
- Don't wait to invite the guests: The paper argues that bringing the public in late in the process (which they did in this project) is inefficient. It suggests that if you bring them in from the very start (during the "Design" phase), it might actually save money in the long run and make the research better.
- Don't let the seniors do all the work: The paper points out that senior researchers spent a huge amount of time on "lower-level" tasks like admin and scheduling. They suggest that junior staff should take over these tasks earlier. This would let the seniors focus on big-picture stuff and save money, because junior staff are paid less.
- Don't assume it's cheap: The paper confirms that Patient and Public Involvement (PPI) is "resource-intensive." It's not a magic trick that costs nothing; it requires a serious investment of time and money.
How Sure Are They?
The authors are very confident in their numbers for the "Implementation," "Operation," and "Evaluation" stages because they had real records of hours and payments. However, for the "Design" stage, they admit they had to use estimates because they were looking back at the project after it happened. They couldn't perfectly separate the design costs from other research costs. So, while they are sure that senior staff time is the biggest cost driver, the exact dollar amount for the design phase is a bit of a guess.
The Bottom Line
This paper is like a receipt for a very complex project. It tells us that running a patient advisory board isn't just about writing a check to the patients. It's about paying for a whole support system of researchers, managers, and assistants. The authors suggest that if we want to do this right, we need to stop treating it as an extra expense and start building it into the foundation of research from day one, using junior staff to handle the busy work so the whole thing runs smoother and cheaper in the long run.
