Health Services Productivity Paradox

This study explores the measurement of productivity within the service sector, in this case the state government sector of health. The algorithm for productivity is relativity simple, and has been applied to the health sector after statistical first principles have been applied, nonvested and normalised data. Not only can the entire health system be measured for productivity but so can each health region, subcategories with the region, e.g. community health, and honed to determine the productivity of professions within the subcategories. This was done for one region in the NSW health system, for community health examining nurses and therapist. For nurses only productivity from 2005 to 2012 has dropped 300% while the health budget had continued to expand, the productivity paradox; the simple correlation between the patients served and the cost of serving each patient has expanded from $756 in 2005 to $3262 in 2012. A very reflective study and correction of the productivity paradox within the NSW health system needs a very careful review. Health Services Productivity Paradox Ronald Hicks, Ph.D. Australian Health Research Centre Productivity is defined as; an average measure of the efficiency of production. It can be expressed as the ratio of output to inputs used in the production process. When all outputs and inputs are included in the productivity measure it is called total productivity [1]. The amount of output per unit of input (labor, equipment, and capital). There are many difference ways of measuring productivity. For example, in a factory productivity might be measured based on the number of hours it takes to produce a good, while in the service sector productivity might be measured based on the revenue generated by an employee divided by their salary. In the Government Health Services productivity is a concept seldom applied and when/if the concept is applied numerous problems occur, more about this later [2]. Simply, productivity is a measure relating a quantity or quality of output to the inputs required to produce it. Labor productivity, can be measured by quantity of output per time spent or numbers employed [3]. Productivity is a ratio that describes the output divided by the input, Productivity = Output/ Input [3]. Increase productivity can be gained by either increasing output or decreasing input. Productivity is how much goods and services are created by an investment of workers and money. High productivity creates more output with less input. It's more valuable because it creates greater profit. It gives the company, industry or country an advantage over their competitors. Productivity measures are used in many ways. governments use them to evaluate whether laws, taxes and other policies increase or impede business growth. Businesses constantly analyse and try to improve productivity in processes, manufacturing and sales to improve the bottom line. In 1994, Nobel prize-winner Paul Krugman summarised most economists' views about the importance of the standard measure of productivity: output per worker [4]. In The Age of Diminishing Expectations 'productivity isn't everything, but in the long run it is almost everything. A country’s ability to improve its standard of living over time depends almost entirely on its ability to raise its productivity [4]. Central banks analyse the overall productivity of an entire economy, to see how well total capacity is being used. If productivity is low, then the economy is in recession. If capacity utilisation is high, then the economy may be in danger of inflation. For these reasons, productivity growth is desired [5]. Most government services especially health involve multi-factor productivity, or, In total factor productivity, can be functional defined in an algorithm [6]. This study is not a multi-factor (total factor) study, rather a basic study government service productivity. MFP = d(ln f)/dt = d(ln Y)/dt sLd(ln L)/dt sKd(ln K)/dt where:: f = the global production function; Y = output; t = time; sL = the share of input costs attributable to labour expenses; sK = is the share of input costs attributable to capital expenses; L = a dollar quantity of labour; K = a dollar quantity of capital. In this study parameters sK, sL and K will not be used and this algoithm will be condensed to utilised on singular units of service. Method This study obtained its data via publicly available sources for one the eight regional health services in NSW. Two first principles of data acquisition were applied to the basic data [7]. Firstly, no data collected by the health service was used; company data often has numerous bias agendas. If data can be corrupted, it will be. Public domain data was used, which does not insure its reliability. This data was non-normalised. The health system data was normalised using additional information from open sources, hence suitable for statistical analysis. Secondly, database semantics were applied when possible [7].
