Variation in Costs 

The table above shows us two drastically different results. ABC helps us recognise that although the ‘fractured arm’ procedure incurred the greatest volume, the other two procedures were a greater drain on costs. This highlights the inaccuracy’s that can occur due to the simple nature of the traditional costing method and even in this basic example, the strength of ABC is shown, when there are a variety of procedures in place. ABC costing works by identifying how resources are being used (staff time, work space, equipment hours etc.) and allocates them directly to the activity that uses them.

The discussion so far has provided a broad outline of ABC however; the following diagram gives us a more insightful indication of how the process works (Miedema, 2010, 6.7) In the first stage, costs are allocated to activities or cost centres this is known as a resource driver e.g. the wage of a hospital cleaner could be allocated to the activity pool of cleaning or, the equipment cost of an x-ray machine to the activity pool of X-Rays. The second stage is where the activities are related to the product or service, known as the ‘cost driver’ e.g. the fractured arm requires the X-Ray activity

pool and so costs could be proportioned according to usage (using the cost driver ratio). The direct cost is then added to achieve the total cost for an activity or service.

ABC helps managers control indirect costs and monitor efficiency of services and activities therefore; it is a very useful instrument. However, ABC has a number of limitations or disadvantages. The first of these is that an ABC is extremely costly to implement and maintain. According to Meyer and Rowan (1977, pp. 91) efficiency and institutional pressures contradict one another and these pressures have a negative influence on the institutions. This is in reference to the drive for ABC from senior stakeholders (government, senior management etc.) to promote efficiency although, the process of ABC itself could be classed as inefficient in terms of cost and time, its real advantage however, it makes managers aware of the drivers that force costs to be incurred.

Secondly ABC still relies on judgement and interpretation. This is in terms of drawing information from the presented data and determining the value of the cost drivers. As it is impossible to create recognised standards for each procedure, there will always be contentious points when using this method. Finally ABC does not offer a complete solution to all costing issues, some costs simply cannot be categorized and so fall into the ‘business sustaining’ category. This category’s costs have to be fulfilled by contributions from all procedures e.g. the chief executive of a hospital has a salary which cannot be categorized into any specific activity.

Variation in Costs Now we have explored ABC we have an understanding of how the NHS formulates its costs. This gives us the platform to further explore some of the variances between the hospitals within the NHS. It is important to understand the costs reported are influenced by a high degree of variables some of these occur within the ABC costing method however, there are also external factors to take into account.

One of the most important factors is the individual and diverse nature of health care. Different individuals require different degrees of care, for example; a 20 year old man who breaks his leg is on average, likely to require a lower degree of care than a 75 year old man who breaks his leg. This may be due to the fact the older man might require to stay in hospital or require other treatment as a result. This is expressed by the department of health here “Costs can differ due to the different drug regimes required because of the severity of the condition when the patient is admitted, and due to the length of time in hospital” (DoH, 1999, p.15).In reference to the cost variation over different hospitals, the fact that we can’t predict just which individuals, require which procedures means discrepancies will always exist between the various trusts. Although this will have an effect, its influence on the results can be argued and other factors are involved.

One of the major contributions to hospitals costs are its utility expenses. Different hospitals will have varying degrees of utility costs to cover e.g. an old inner city hospital in the centre of London; will have a much higher utility bill than a newly built energy efficient hospital elsewhere. Factors such as this will undoubtedly have a significant impact to the overhead costs which, are then passed down to the activity cost.

Another variable in costing may occur due to Geographic location. This is evident in the higher salaries paid out in certain geographic locations which, are ultimately pushed through to the final costing figures of activities. Finally an absolute key factor is the diverse range of procedures offered by hospitals. The consequences of this are that a truly NHS wide standardisation for individual procedures is near to impossible as seen in the trouble with clinical coding practices. These are designed to encourage standardisation across the NHS however, the problem is the quality of data varies which; ultimately, this leads to individual interpretation and flexibility. This result of this is that the way costs are defined, plays a significant role in final costing figures (cost drivers, Resource pools etc.).

Conclusions

“The underlying assumption is that cost variability, (i.e. where different NHS Trusts report different costs for the same clinical treatment), highlights inefficiency between Trusts.” (Northcott, 2003, p5) This inefficiency is what Gordon Brown refers to as ‘poor management’ however, Costing within the NHS is both complicated and hosts many problems. To describe the inefficiency’s as poor management is a far too simple assumption. To truly be able to describe the variances as inefficient, the results have to be put in to context against other indicators which bring with them definition problems of their own.

It is clear, that the problem remains in standardizing the ABC costing procedure across the NHS (the current system leaves too much room for flexibility between hospitals). Although comparing efficiency’s and promoting benchmarks encourages good performance, until ‘true’ standardisation across the health service is employed it cannot be effectively used as a measurement. Because of this Gordon Browns comments cannot be justified or expressed with absolute clarity.

At the heart of the problem is the drive for hospitals to be viewed as ‘business like organisations’, costing methods such as ABC, only help to promote these views by putting an intense pressure and increased competition on hospitals in terms of efficiency and performance. Until hospitals return to what Chapman (p2) refers to as a ‘patient-centred organisations’ we will continue to see a focus on resources rather than the most important issue – the patient.

Recommendations An NHS standard for each individual procedure is the only way to truly measure the efficiency of a hospital and this should be the aim for moving forwards. It is important to remember that even then context is required to consider other factors. Finally a more radical response would be to cut the problem from the source (the wide range of services offered) and promote ‘centres of excellences’ for specific procedures within areas. By cutting the range of activities, costing and measuring efficiency becomes a more realistic target, whilst at the same time promoting specialism.
