Measurement of healthcare outcomes is one of the important strategies that healthcare providers use to improve the delivery of healthcare services. When delivering healthcare services, healthcare providers are often interested in the analysis and understanding of the impact of their service and whether health outcomes align with their objectives. Measurement of any healthcare outcome requires the healthcare providers to use vital tools that help to reveal the impact of various medical practices and interventions. When carrying out an outcome measurement, healthcare providers must choose various tools to use from an array of proven methodologies for the outcome measurement. There are vast measurement methodologies, and one’s choice depends on a number of factors. There is a multitude of current methodologies that healthcare providers utilize when measuring various healthcare outcomes. These methodologies include Achenbach Questionnaires, Diagnostic Interview Schedule for Children, Client Satisfaction Questionnaire, and Children's Global Assessment Scale.
Achenbach Questionnaires is an outcome measurement tool that has 118 items that focus on problems facing children and adolescent. Physicians can administer this tool after providing an intervention to gather some data on frequency of behavioral problems. This method is critical in measuring the effectiveness of clinical intervention that is given to children and adolescents. Diagnostic Interview Schedule for Children is another methodology that healthcare providers use to measure an outcome of diagnosis. In this methodology, healthcare professionals can measure the presence of mental disorders through a structured interview. Nonprofessional interviewers can also make use of this methodology to access healthcare outcome with regard to mental disorders. When it is necessary to measure patient satisfaction, healthcare practitioners often rely on Client Satisfaction Questionnaire. This questionnaire provides proven methodology for measuring the level of satisfaction among patients after receiving medical care or intervention. Healthcare providers who are interested in measuring functional status can use Children's Global Assessment Scale methodology to achieve this objective. This methodology excels as it provides healthcare practitioners with detailed information concerning the outcome of an intervention.
There are various challenges that emerge during the measuring of outcomes. Lack of reliability is one of the challenges that have a direct impact on healthcare outcomes. All methodologies should at least have some level of reliability. However, some of them can produce inconsistent results that can affect outcome measures. To remedy this situation, there is a need to reduce the impact of interferences, such as removing test items that may result in confusion. It is also necessary to remove the element of bias in a test in order to increase reliability. Another challenge of measurement methodologies is the validity of a test. The validity of measurement methodologies can be increased through the clarification of test and its comparison to available data. This strategy can help reduce the impact of the lack of validity in the above mentioned methodologies.
