Critical appraisal is “the process of systematically examining research evidence to assess its validity, results and relevance before using it to inform a decision” (Hill & Spittlehouse, 2003). Instruments developed to support quality appraisal usually share some basic criteria for the assessment of qualitative research.
How to conduct a rapid critical appraisal?
A rapid critical appraisal (RCA) is simply evaluating a study for its worth, based on its validity, reliability and applicability to clinical practice. Generally, an RCA involves some kind of a checklist to help the reviewer quickly determine the appropriateness of the study and whether it can apply to their patients.

Introduction
Critical appraisal of qualitative studies determines different aspects that should be observed in carrying out research. It touches on the aims of the research, the appropriateness of the use of qualitative methodology, the research design, the recruitment strategy, and data collection, among other elements as highlighted in this paper.
Aims of the research
The research paper had a clear statement of aims. The paper sought to establish how primary care clinicians arrive at different evidence-based decisions, whether individually or collectively (Gabbay & May 2004).
The appropriateness of qualitative methodology
The researchers sought to shed light on some of the underlying explanations to the highlighted dilemmas by seeking the experiences of the participants. Qualitative research was the best methodology as it captured the participants’ experiences, which were critical to the objective of the study (Gabbay & May 2004).
The appropriateness of research design
The research design was appropriate as the researchers discussed how they decided the method to use. The researchers chose ethnography data collection, analysis, and interpretation, which allowed them to interact with the participants and obtain relevant information using structured and unstructured participant and/or non-participant strategies.
The appropriateness of the recruitment strategy
The recruitment strategy was appropriate for the aims of the research. The researchers noted that they selected the participants from local and urban learning institutions with different ethnographic characteristics. The researchers chose nine doctors from different areas of specialisation to get inclusive responses.
Data collection
The setting for data collection was not justified, but the researchers mentioned that they used two different locations in disparate environments. One location was in rural areas while the other one was in the urban area, but they did not justify why they chose such places.
The relationship between researchers and participants
The relationship between the researcher and participants has not been considered. The researchers did not mention if they examined their own role, potential bias, and influence on the formulation of the research questions or data collection.
Questions to Ask
Did the paper describe an important clinical problem addressed via a clearly formulated question?
How to Find Qualitative Studies
1. Use thesaurus terms. Qualitative research is indexed in PubMed as "Qualitative Research" or "Nursing Methodology Research", while in CINAHL, the subject heading "Qualitative Studies" is complemented by more detailed terms, including "Phenomenological Research" and "Grounded Theory".
Why is qualitative approach effective?
The qualitative approach is effective since the statement of the problem refers to qualitative (infinite) aspects, i.e., unquantifiable variable. It answers the “How” aspect of research, characteristics to which it is not possible to assign numerical figures.
What are the key findings of the study?
The key findings were that the process of internalizing the effects of preterm births took time to establish. With time, parents became more confident and familiar with their experiences. The findings are very clear and thorough and the researchers do this by connecting the data collected to their discussion. they are also easy and clear to understand because of the use of illustration s of the views of parents and clear articula tion of key points raised in the interview
Is data analysis qualitative or phenomenological?
The data analysis method use was phenomenological, that is, describing situations as they are experienced by human subjects (Chiorgi, 2000 p 13). Yes, the approach was in tandem with the qualitative approach used, since it explained the effects that preterm births have on parents who experience them.
Is qualitative research appropriate?
The research approach of this study is a qualitative methodology. Yes, it is appropriate as it addresses the research question. The aim of the study is to describe experiences, and not find out their prevalence. It seeks to examine how parents respond to preterm births, rather than how many preterm births occur.
Is the data collection method comprehensive?
No, the data collection method was not comprehensive. Given the fact that they were researching on aspects that examine one’s character and values, it is possible that the respondents adjusted their responses accordingly.
Is the information given about the researchers relevant?
Yes, the information given about the research ers is relevant. It reveals their field of specialization, which I think is relevant to this study. Karin is a lecturer in the department of Caring Sciences, Britt-Marie department of Health Care Sciences and Jens a professor in paediatrics.
Is qualitative or quantitative methodology appropriate?
Yes, the qualitative approach will be appropriate for this study. I would like first to disqualify a quantitative methodology. This approach takes into consideration numerical statistics that reflect the prevalence or seriousness of a phenomenon. In other words, it draws conclusions from numbers. If it were to be used for this research, the aim of the study would have been to find out the prevalence of preterm births in a given area. I purposely add ‘in a given area’ since occurrences of phenomena, unlike their characteristics, are limited to the geographical area covered by the study. For instance, a study on the prevalence of crime in California will not be stretched to reflect the reality in Chicago. Thus, a quantitative approach would have been limited to addressing a situation in the specific region in Sweden where it took place. The qualitative approach is effective since the statement of the problem refers to qualitative (infinite) aspects, i.e., unquantifiable variable. It answers the “How” aspect of research, characteristics to which it is not possible to assign numerical figures. Consequently, a qualitative methodology is appropriate for it describes aspects of behaviour that portray values, beliefs etc.
