The purpose of this essay is to critically examine the methodological process employed in a narrative review focused on managing workplace stress among care workers in the UK. The review involved searching three databases after establishing research questions and eligibility criteria, resulting in twelve included studies. While narrative reviews offer flexibility in synthesising diverse literature, the process described reveals several limitations in search comprehensiveness, screening rigour and study selection. This critique draws on established principles of literature review methodology to highlight strengths, such as the appropriate stance on ethical approval, alongside significant weaknesses that undermine the reliability of findings. The analysis remains grounded in health and social care perspectives relevant to undergraduate study.
Database Selection and Search Strategy Limitations
The choice of PubMed, Medline and CINAHL represents a reasonable starting point for health-related topics, given CINAHL’s focus on nursing and allied health literature. However, substantial overlap exists between PubMed and Medline, which likely inflated the initial yield of 725 articles before duplicate removal. A more efficient strategy would have incorporated discipline-specific databases such as PsycINFO or Social Care Online to capture psychosocial dimensions of workplace stress. The reported removal of only 95 duplicates from 725 records suggests possible under-detection of overlaps, a common issue when relying on basic reference management without advanced deduplication tools. Furthermore, omission of grey literature sources, such as government reports from Skills for Care or NHS England, restricts the review’s applicability to UK policy contexts where much workforce stress research appears outside peer-reviewed journals.
Screening and Selection Process
The reduction from 630 unique records to 28 after title screening, and then to 12 after abstract review, indicates highly selective criteria. While this aligns with the predefined eligibility parameters, the absence of details regarding the number of reviewers involved raises concerns about single-reviewer bias. Best practice in evidence synthesis recommends dual independent screening with consensus procedures or inter-rater reliability checks to minimise subjective decisions. Without such safeguards, potentially relevant studies on stress interventions may have been excluded inadvertently. The final inclusion of twelve studies forms a modest evidence base for a narrative review, which can be acceptable when exploring emerging topics, yet it limits the depth of thematic synthesis possible. The process would have benefited from a PRISMA-style flow diagram to enhance transparency, a standard expectation even in non-systematic reviews within health and social care education.
Study Inclusion, Date Anomalies and Synthesis Challenges
The cited studies, including those dated 2026, present a fundamental problem because publications from future years cannot be accessed or verified at the time of writing. This anomaly suggests either placeholder references or errors in record keeping that compromise the credibility of the data collection phase. In health and social care research, temporal relevance matters greatly; stress experienced by care workers during events such as the cost-of-living crisis requires up-to-date evidence. Reliance on a small set of studies also means the narrative synthesis may over-emphasise particular themes, such as moral distress or psychological first aid adaptations, without adequate counterbalancing perspectives. Narrative reviews generally tolerate broader inclusion than systematic reviews, yet they still demand explicit quality appraisal of included papers, which is not described here.
Ethical Considerations
A clear strength lies in the recognition that secondary analysis of published literature requires no primary ethical approval. This aligns with common UK university guidelines and avoids unnecessary delays. Nevertheless, the review should still have addressed issues of accurate attribution and potential misinterpretation of original authors’ findings, especially when synthesising sensitive topics such as workplace stress in under-resourced care settings.
In conclusion, the described process demonstrates basic competence in database searching and an appropriate ethical stance but is limited by overlapping database choices, inadequate transparency in screening, an unrealistically small final sample and unverifiable future-dated references. These shortcomings reduce the review’s potential to inform practice or policy effectively. Future narrative reviews in this area would benefit from expanded database coverage, dual screening protocols and rigorous checking of reference validity to produce findings more trustworthy for UK health and social care contexts.
