This essay aims to critically appraise a quantitative research study with the use of a critical appraisal tool. The study (O’Keeffe et al 2010), considers ambulance response times and their role in the survival of patients in out of hospital cardiac arrests. A quantitative study was chosen as quantitative research is based on numerical data and statistics whereas qualitative can be subjective and opinion based, (Barker et al 2016). Previous experience in statistics and numerical based research encouraged selection of a quantitative research paper. A critical appraisal tool developed by Cauldwell et al (2005) was selected due to a better understanding of the questions within the framework giving an enhanced ability to apply the framework questions …show more content…

It is stated that ethical approval was gained from ethics committees covering the hospitals that would be connected to the study, and per Barker et al (2016) all research related to health care has been required to gain formal ethical approval since the Research Governance Framework was made law in 2004. This shows ethical issues were obviously addressed for the study to have been conducted and published, however no details of what the ethical issues specifically were or how they were addressed are given in the paper, such as confidentiality of patient identifiable information and anonymity or informed consent, key ethical concerns when conducting research, (Fox & Byatt 2008).

This is something that could be argued when critically appraising the reviewed study.
Following the use of an appropriate critical appraisal tool, it can be seen that the study by O’Keeffe et al (2010) has its strengths and its weaknesses. The critical appraisal tool (Cauldwell et al 2005) has enabled a systematic breakdown and evaluation of a quantitative research paper to conclude further study and steps would need to be taken for O’Keeffe et al (2010) to be classified as a flawless quantitative research
