近年来，由于科技和药物的发展，人们的预期寿命有所提高。人们的平均预期寿命从1980年的70.2岁增加到2010年的76.2岁。研究发现，男性人口的平均年龄为77.4岁，女性人口的平均年龄增加到81岁(NHS, 2014)。种族差异降低了平均预期寿命。研究发现，所有种族，尤其是白人、黑人和西班牙裔人口的平均预期寿命都更高。这是一个进步的趋势。然而，人们发现，处于后期阶段的人民需要不断的医疗照顾和必要的服务，这是他们维持生计所必需的。男性和女性的死亡率分别下降了16%;它已经下降到13%。这些数字令人鼓舞，但医疗质量问题已被分析(NHS, 2014)。研究发现，随着年龄的增长，人会患上一些疾病，如癌症、糖尿病等。这增加了维持卫生保健的现有负担。除此之外，人口也出现了反增长。由于科学技术的发展，无限死亡率已大大降低。这是因为科学(NHS, 2014)。但是随着人口的增长，需要卫生保健和卫生相关服务的人数将会增加。这是当前医疗体系面临的一个问题，该体系已经承受着维持当前医疗质量的巨大压力。通货膨胀也需要考虑到这个问题(NHS, 2014)。
现在有必要对现有体系进行调查，以了解向人民提供的医疗服务的质量。为了开发健壮的协议来解决这个系统，需要分析现有的系统。因此，已经进行了一些研究来分析现有的进程。McGlynn等人(2003)进行了一项关于医疗质量的调查。研究发现，不同人群的健康状况不同，护理质量也不同。研究表明，向人民提供的医疗服务质量存在严重缺陷，应该进行某种形式的制度改革(McGlynn et al.， 2003)。在这项研究中发现，大多数人认为医疗质量是不平等的，他们想要一个系统，它将是平等的，适合人民要求的服务。这些结果也表明了人们对美国医疗体系的总体不满。他们都认为，在这种情况下，系统可以得到改进(McGlynn et al.， 2003)。
In the recent years, owing to the increase in technology and medication, there has been an increase in the life expectancy of the people. It has been found that the average life expectancy of people increased from 70.2 years to 76.2 years from 1980 to 2010. It was found that the average age of male population was 77.4 years and for female population, there has been an increase to 81 years (NHS, 2014). Racial disparities have reduced in the average life expectancy. It has been found that across all races especially the white, black and Hispanic population, the average life expectancy of the people was found to be more. This is a progressive trend. Nevertheless, it has been found that the people in the later stages require constant medical attention and mandatory services that are required for their sustenance. Death rate has decreased by 16% in male population and in the female population; it had decreased to 13%. These numbers are encouraging but the quality of care issues has been analyzed (NHS, 2014). The people along with their age are found to develop some conditions such as auto immune condition such as cancer, diabetes, etc. This has added to the existing burden of maintaining health care. Apart from those, there has been anti-increase in the population. Infinite mortality rate has reduced dramatically owing to the development in science and technology. This is because of the science (NHS, 2014). But with the growing number of population, there will be an increase in the number of people who will need health care and health related services. This is an issue for the current system that is already under tremendous stress to maintain the current quality of care. Inflation also needs to be factored into this issue (NHS, 2014).
Now there is a need to probe into the existing system to understand the quality of care that is provided to the people. There is a need to analyze the current existing system in order to develop robust protocols to address this system. Owing to this, there have been a number of researches that have been undertaken to analyze the existing processes. McGlynn et al., (2003) undertook a survey about the quality of health care. It was found that the quality of care varied according to the different health conditions for the people. The research stated that there was serious deficit in the quality of care provided to the people and there should be some form of system change (McGlynn et al., 2003). It was found in this research that majority of the people felt that the quality of care was not equal and they wanted a system where it would be equal and appropriate for the services requested by the people. These results also indicate the overall dissatisfaction of the people regarding the health care system in the United States. They all felt that the system can be improved given the circumstances (McGlynn et al., 2003).
Health care costs and managing health care has been widely debated topic. All the people in the society are expected to utilize the services of the health care system at some point in their life. In this system, two major issues are preventing in providing holistic care for the patients. To improve the quality of care, there are two facets that are explored. It is the rising costs of health care and the issues form overmedication or improper management of the hospital staff.
