Arguments in favour of using the Balance of Care model at the local level.
imp strength is its its logic and structure.
This has provided a framework for:
(a) bringing together the many different agencies and professions involved in providing long-term care for elderly people and stimulating substantive discussions
about how to define dependency groups and alternative modes of care for each group;
(b) taking population needs, rather than particular resources or services, as the starting point for planning;
(c) pulling together and organizing existing information, and identifying needs for additional information.
The fact that the model runs fast on a personal computer has the advantages of:
(d) responsiveness. Once the model has been set up, it is possible to evaluate a range of planning scenarios quickly; thus it is possible to try out a planning idea, look at the results, and make successive revisions until a satisfactory balance is achieved.
(e) portability. The model can be used in different people’s places of work; results can be projected onto a large screen, so that there can be widespread participation in the planning process, which is desirable when so many agencies are involved.
2 Potential problems and weaknesses.
These fall into two categories: problems with data and problems with the process.
Problems with data include the following:
(a) Collecting local primary data can be costly and time-consuming. If data collection takes a long time, this can lead to planning blight in which even the most obvious planning decisions are not made because the decision makers are ‘waiting for the
model’.
(b) The model provides age- and sex-specific rates for each of the dependency groups from several representative areas. These can be applied to the demographic structure of the local population to get round the need for local data.
But very little is known about the accuracy of estimates based only on these two factors and how much real needs vary from one area to another.
(c) In practice, each additional case cared for in a particular mode will not involve the same marginal cost.
However, the model’s linear approach to cost estimation
Models for service planning and resource allocation
ignores effects such as returns to scale and cost triggers (such as opening a new ward or taking on an additional member of staff). Arguably this is more of a
problem with using the model for local than for regional or national planning.
Problems with the process include:
(d) Meetings required for real collaboration are time-consuming; senior staff may not give the necessary time; juniors may not have the necessary authority to
commit their organization to any resulting plans.
(e) Any model of this kind requires estimates of the amounts of resources necessary to provide care of an acceptable standard within each mode (care option). Although experience with the model suggests that it is generally possible to establish a consensus on this,
there can be difficulties, particularly if there is a lack of goodwill or if certain provider agencies are trying to gain an advantage.
It is commonly argued that as a basis for providing care for individuals, these groups are too crude; two people in the same group could have very different needs for care. But this is a planning tool, not a set of treatment guidelines. |
