Parkinson’s New Zealand’s Social Impact Evaluation

The main goal of Parkinson's New Zealand Charitable Trust is to provide targeted services that enable people with Parkinson’s (PwP) to enjoy a better quality of life for longer and to support their caregivers and whanau.

From this goal, Deloitte identified three measurable social impacts to estimate the value of the services PNZCT provides:

  1. Better physical health outcomes for PwP
  2. Better mental health outcomes for PwP and their whanau
  3. PwP are better able to manage their condition and wellness

To monetise impact from the three outcomes identified, Deloitte used a ‘quality-adjusted life years (QALYs) formula utilising internal data collection, the Annual Client Satisfaction Survey (2020), and
other sources to estimate the social impact of the service.

The Social Impact Evaluation estimates the social impact of PNZCT’s services for the 2019/2020 year at $15.9 million.

During this same period approximately $3 million was spent by PNZCT to provide these services. The value of PNZCT social impact is therefore estimated to be more than five times greater than the amount invested.

Along with an estimate of PNZCT’s social impact, the Board wanted to quantify how much our services saved the health sector. Deloitte calculated the potential savings to District Health Boards by estimating how many GP visits may have been avoided due to the interaction by PwP with their PNZCT’s nurses and educators. Deloitte estimated a potential savings of $1,273,628 to the health sector in 2019/2020.
