Describe another example of quantitative research design. How do quantitative research designs improve quality of care and health outcomes?


Quantitative research design refers to a systematic methodology which is used to test relationships between variables through collection of data. Data can be collected through surveys, questionnaires, interviews and secondary methods such books and magazines. The data is then analyzed using statistical approaches and presented in form of numeric. Quantitative research designs are grouped into descriptive and experimental measurements. Descriptive describes the relation between the variables researched while experimental explains the cause of the variation. Quantitative research design is a reliable research method and can be used to sample large populations (Creswell, 2013).

Descriptive design

Descriptive design is an example of quantitative research method and it uses statistical analysis to compare variables through the data collected. Descriptive design does not seek to establish the cause effect but the existence of relationship between the variables. Descriptive research design is reliable research method and the results achieved can be used to control health outcomes and improve the quality of services provided at the hospitals (Solheim et al., 2017).

Application of research in healthcare

Quantitative research designs provide information which can be used by healthcare professionals to improve medications and deliver quality services. Some medicines were discovered long time ago and due continued research new elements have been discovered to boost the efficiency of the medicines. Improved life supportive machines have also been introduced as a result of the quantitative research design (Houser, 2016).

Research findings from quantitative research designs can be used to initiate and improve techniques and procedures used by healthcare professionals. This saves time and resources used in treatment which the ultimate goal of most of the hospitals. Quantitative research design has also resulted to improved information and communication technology which is integral in improvement of healthcare services. Hospitals are now able to use computerized record system which has reduced medical errors and improved the safety of the patients. Lastly, through quantitative research method some diseases like cancer which were known to be incurable can be treated. The rate of deaths due cancer has reduced and other diseases such as HIV/AIDS which has now prevention (Houser, 2016).

In conclusion, quantitative research method is of high importance in redesigning the health care system and improving the quality of services delivered. Descriptive design approach being an example of quantitative research design establishes relationship between the variables through statistical analysis which is readily reliable.
