Background to the working party:
The Health and Care Research Sub-committee has launched a member-led working party to support the development of population health management. The NHS is tackling the challenge of rising healthcare demand and constrained funding by implementing new models of care to develop integrated local healthcare systems for a defined population. To underpin delivery of the improved outcomes, better care and value for money that are being sought, it is essential that healthcare systems develop a comprehensive understanding of the health characteristics of their population – for example, current patterns of care demand, forecasting future demand, and predicting the effects of interventions. The actuarial skillset has much to offer in building and deploying such demographic, risk modelling and analytical capability, but there is currently limited awareness of this across the NHS.
Population Health Management considers the distribution of health outcomes within a population and how to impact these outcomes in the most optimal way for the group as a whole. It is a wide field and so the working party will initially focus on the specific topic of impactability modelling. The predictive risk stratification and segmentation models typically utilised in population health approaches have focused on identifying population groups that have a high risk of experiencing an adverse event, such as an unplanned hospital admission, or have a high cost profile.
However, the success of risk stratification at the whole-population level depends not just on identifying those most at risk of an adverse event, but rather in identifying those who are most at risk and most likely to respond positively to a given intervention – i.e. to be ‘impactable’. The combination of risk stratification, impactability modelling and actuarial variability analysis can not only help to target the most promising patients for medical management, but also support the improvement of resource allocation across a local health economy.
The research and output of the working party will be done in phases, with the scope of each phase to be defined and agreed once the working party is established. Initially, it is envisaged that a range of topics related to impactability will be explored, including:
- definition of impactability modelling – (e.g. analysis which quantifies the extent to which a defined population cohort is predicted to respond to a given healthcare intervention under specified circumstances)
- exploring an understanding of different approaches to measuring and modelling impactability including the skills, tools and techniques needed to achieve each approach
- the advantages and disadvantages of various potential approaches (both data driven and those based on empirical evidence)
- consideration of the interactions between impactability and population risk management
- issues of public perception, inequality and ethics.
- A presentaton at the Life Conference or Protection, Health and Care Conference or other relevant health conferences
- A research paper due in 2019
- An article in The Actuary
- A sessional meeting

Reimagining ageing, hosted by the Institute and Faculty of Actuaries, in partnership with the ILC
Increasing global concern over the impact of climate change has recently led to public scrutiny over the adequacy of existing risk management practices by insurance firms and pension schemes in dealing with these challenges, that potentially impact both individual actuaries and the IFOA generally.

Fake news, post truth, mistrust of experts... a familiar roll call of anxieties – or perhaps clichés – about our data rich world. They point to an underlying fear that in this data abundant age the bad data drives out the good and we are left with a broken public discourse.

Our motivation for discussing this important subject comes from some exciting recent research which has analysed the impact of behavioural factors on the decision to purchase an annuity. This work has shown that behavioural factors can explain the well-known low demand for immediate annuities but this research also identifies an important opportunity in relation to deferred annuities (DA). The research suggests that these factors lead to positive incentives to purchase a DA and that, for longer deferred periods, a DA could be an attractive product for both consumers and insurers.
