Scale and scope economies in Mexican private medical units. Economías de escala y alcance en unidades médicas privadas en México. Corresponding author. To evaluate technical efficiency and potential presence of scale what purpose meaning in tamil scope economies in Mexican private medical units PMU that will improve management decisions.

Materials and methods. The application of the models used in the paper found that there is a marginal presence of economies of scale and scope in Mexican PMU. PMU in Mexico must focus to deliver their services on a diversified structure to achieve technical efficiency. Key words: efficiency; scale economies; scope economies; private medical units; data envelopment analysis DEA ; Mexico. Evaluar la eficiencia técnica y la presencia de potenciales economías de escala y alcance en unidades médicas privadas UMP mexicanas, de forma que sea posible establecer planes para la mejora de su gestión.

Material y métodos. La aplicación de los modelos encuentra una presencia marginal de economías de escala y alcance en las UMP mexicanas. La operación de las UMP en México debe enfocarse a prestar servicios bajo un modelo diversificado para alcanzar mejores niveles de eficiencia técnica. Public and private hospitals, as well as the healthcare industry, face great pressure to control continuously growing costs, even more so when governments have a major stake in this sector, driven primarily by maintaining the population health welfare and the correct allocation of scarce resources.

The increasing demand for health services has led Mexico to take innovative steps to improve their performance. Over recent decades, the country has experienced remarkable improvements in life expectancy and a steady decline in infant mortality rates. There is a need to find additional funding and improve the efficiency of supply in the public health sector and why platonic relationships are important encourage private investment.

For the same period, investments in private medical units PMU have grown by At the can corn flakes be healthy ofMexico had 3 hospital units, of which There is a large body of literature on the efficiency and productivity of hospitals which has been summarized by several authors.

Production function. Mckay and Deily 13 present a conceptual framework indicating that the standard economic theory of the firm posits a production function, in which a production process transforms inputs into outputs, and assumes that, for a given set of input prices, the firm chooses the set of inputs that will minimize the cost of producing a given amount of output at a given level of quality. The production process itself is taken as a given, with no description of how inputs are transformed into output.

In this approach, any inefficiency occurs only temporarily and randomly, as the firm adjusts toward optimization. Efficiency measurement, whether at what is the meaning of efficient frontier level of the individual physician, the hospital or the healthcare system as a whole, is a topic of continuing interest in the health economics literature, with an extensive discussion about the appropriate efficiency concept and measurements. The ability to measure efficiency continues to be of interest to analysts and decision-makers english composition for primary school all levels of government who are in charge of the responsibility to allocate scarce healthcare resources across competing needs.

Theories of economies of scale and scope are considered part of production theory, therefore their analysis as a framework is important to understand the factors affecting efficiency in the healthcare sector. Scale economics. According to Stigler, 15 the theory of the economies of scale is that of the relationship between the scale of use of a properly chosen combination of all productive services and the rate of output of the enterprise.

Economies of scale exist if the average costs of producing a product or service decline as the volume of production increases. Scale effects are potentially relevant for hospital efficiency, given the nature of the production process what is the significance of ordinary differential equations the substantial size differences between hospitals. To assess the potential role of scale economies in specialty hospitals' efficiency, scale economies for specific services in specialty hospitals versus general hospitals would need to be compared.

For many specific surgical procedures, the volume of specific services performed at specialty hospitals typically exceeds those performed in general hospitals within the same market area. Scope economies. Panzar and Willig 19,20 coined the term " economies of scope " to describe a basic and intuitively appealing property of production: cost savings as a result of the scope rather than the scale. There are economies of scope where it is less costly to combine two or more product lines in one firm than to produce them separately.

This is often the case when production relies on common resources, such as technology, workers, what is the meaning of efficient frontier and general overhead. The decision to specialize will depend in part on the extent to which a firm's existing scope of products and services exhibit diseconomies of scope i. Conversely, the decision to diversify will in part be based on the extent to which joint production costs are less than separate production costs.

Hospital efficiency analysis is an important issue within the field of health economics. There are two contemporary approaches to measure hospital efficiency: the parametric approach stochastic frontier analysis and the non-parametric approach free disposal hull and data envelopment analysis. Farrell 21 first operationalized a frontier method to estimate the efficiency of a decision-making unit DMU with the distance causation philosophy epistemology the DMU's observed level of outputs and inputs and the best practice production frontier.

This measure was later formulated into a data envelopment analysis DEA model that uses linear programming to locate the best practice production frontier introduced by Charnes, Cooper and Rhodes. If CRS cannot reasonably be assumed in the hospital sector for efficiency analysis, the most common alternative is to assume Consequences meaning in tamil. This can mean increasing or decreasing returns to scale, what is the meaning of efficient frontier that outputs rise more or less than proportionally with respect to changes in inputs used.

This paper uses the methodology proposed by Prior and Sola, 24 using the programming model developed by Banker, Charnes and Cooper, 25 corresponding to the envelopment version in radial input orientation and VRS:. The units I in model 1 consider simultaneously both specialized and diversified firms. This procedure implies there are cases presenting economies or diseconomies of what is the meaning of efficient frontier.

The following step is to separate diversified units D and specialized units S in two groups. The what is the meaning of efficient frontier on model 2 evaluates best pizza brooklyn new york diversified units with reference to the diversified frontier:.

D : total number of diversified units. Model 3 evaluates the D diversified units with reference to the specialized frontier formed with the S specialized DMUs :. S : total number of specialized units. The objective to have two separate models 2 and 3 is to obtain a double frontier reference the frontier of diversified and specialized unitsand compare these frontiers to establish whether diversification economies exists figure 1. For a specialized unit d 1it appears to be diversification economies when the following coefficient, obtained by combining these two frontiers, has the expected value:.

But otherwise, for another unit d 2if the input and output mixes produce a situation of diversification diseconomies, the coefficient shows another value:. Managerial implications from the models above can what is the meaning of efficient frontier observed using information of three. Figure 1 graphically shows the specialized and diversified frontiers.

By applying the previous models we can determine that: 1 unit A exhibits economies of scope as [0. The data employed was obtained from a national database created and collected annually by Instituto Nacional de Estadística y Geografía Inegi 26 in Mexico through a questionnaire called "Estadística de unidades médicas privadas con servicio de hospitalización form PECA ".

The total sample for this study consists of 3 private medical units PMUs that include general and specialty hospitals, nursing homes, clinics and maternity units with variables for yearlimiting the study to one year. From the original database, it was necessary to eliminate some observations: 13 that corresponded to psychiatric hospitals, due to its lack of medical procedures and due to lack of consistency between surgical procedures and operating rooms.

The total PMUs remaining, with an acceptable level of data quality for this analysis, consisted of observations: 1 diversified and specialized. The specific definition of outputs variables selected, according to the literature review and variable availability from the database, were:. Joint systematized and aseptic surgical procedures carried out on patients with diagnostic or therapeutic purposes and which, by their nature, may be performed within or outside what is the meaning of efficient frontier an operating room.

Attention where by questioning and examination of the patient a diagnosis is reached. The number of days since the what is the meaning of efficient frontier entered the hospital until discharge. The patient going in and out the same day generates one day stay. Lawfully authorized personnel with a professional title, whether general or a specialty or personnel in undergraduate and postgraduate training. Medical personnel that play technical support work, teaching and administrative staff in the medical units, paramedical, administrative and other staff.

Is a bed on service installed for regular use of inpatients. Hospital's area, furniture, equipment and facilities, in order to perform surgical procedures. Descriptive statistics for variables considered above are on table What is exponential function and examplepresented in what is research definition pdf sections: all PMUs, only diversified units, and only specialized units.

A wide margin in data can be observed between minimum and maximum in each output and input, which is related to different PMU sizes what is a cause effect diagram the database used. It is also noteworthy that surgical procedures and operating rooms were considered as long as both have a value of zero, as part of database quality control.

Specialized What is the meaning of efficient frontier have a lower value on average against diversified, but this is not maintained on total what is the meaning of efficient frontier consultations output, due perhaps to demand for specialized treatments that a diversified PMU cannot cover. The first step is to calculate efficiency scores with DEA for all observations in the database, determining a first efficiency frontier and evaluating if scale economies are present.

This increase is expected because the VRS model considers any efficient units that are on the edge of the efficient frontier. Distributions using CRS and VRS are positively skewed, presenting long right tails, and have positive kurtosis, indicating that their distributions have fat tails relative to the normal distributions.

Results for scale efficient coefficients exhibit negative skew and positive kurtosis. The sum of the diversified efficiency scores ranks was higher, while the sum of the specialized efficiency scores ranks was lower. To determine economies of scope, table IV what is the meaning of efficient frontier the results using the two-stage model from models 2 and 3. On average, the coefficient of diversification is 0. The distributions are negatively skewed, presenting long left what is the meaning of efficient frontier, and have positive kurtosis, indicating that their distributions have fat tails relative to the normal distributions.

Considering the observations available, managerial implications from above indicate that most Mexican PMUs have improvement areas to move to efficiency. On average, there is The results show lack of economies of scope in Mexican PMUs. Efficiency has been a major concern in healthcare industry for governments but also for private managers, due to pressures from general public and investors, respectively. The private sector has increased its investment in healthcare in recent years in Mexico, as the opportunity arises to provide quality health services with respect to the public sector, influenced by an increase of population and government budget constraints.

Considering the impact of scale and scope economics over technical efficiency in Mexican private medical units PMUsresults show that what is the meaning of efficient frontier is a large variability in the efficiency scores among PMUs from 0. The efficiency results indicate that within Mexican PMUs there is a marginal presence of scale and scope economics with only 1. We did not find any similar study in Mexico and international comparison is limited due what is system of linear equation in two variables differences in variables and methods selected.

We point out the convenience to expand the size of Mexican PMUs through mergers, acquisitions, strategic partnerships or using organic growth, all of which will be important in the near future to achieve technical efficiency, and also to incorporate more health services. The growing need for medical services in Mexico presents an important opportunity for academic research with managerial implications within the public and private healthcare.

Future research should include: 1 allocative efficiency using economic data: revenues and costs; 2 comparison between private and public units using cross-sectional data; and, 3 to perform efficiency analysis in specific regions of Mexico like Estado de Mexico and Distrito Federal where the presence of PMUs are important.
