Systematic reviews: Structure, form and content

Nursing experiences in specialized services in child and adolescent mental health: a systematic review of qualitative studies

OBJECTIVE

to synthesize evidence from qualitative studies on nursing experiences regarding child and adolescent mental health care in specialized services.

METHOD

a systematic review with meta-synthesis of qualitative studies according to JBI guidelines. CINAHL, EMBASE, MEDLINE, LILACS, PSYCinfo, Scopus and Web of Science databases were used. The findings were classified according to the level of reliability and credibility and categorized by similarity between contents.

RESULTS

229 articles were identified, and five were included in the final sample and organized into the categories: Emotional impact; and Understanding nursing role. The level of evidence found was moderate.

FINAL CONSIDERATIONS

nursing experiences are permeated by emotional exhaustion, feelings of frustration and difficulty in understanding their professional role. The need for training spaces that qualify this care is highlighted.

Older adults' experiences during the COVID-19 pandemic: a qualitative systematic literature review

OBJECTIVES

Relatively little is known about the lived experiences of older adults during the COVID-19 pandemic. We systematically review the international literature to understand the lived experiences of older adult's experiences during the pandemic.

DESIGN AND METHODOLOGY

This study uses a meta-ethnographical approach to investigate the included studies. The analyses were undertaken with constructivist grounded theory.

RESULTS

Thirty-two studies met the inclusion criteria and only five papers were of low quality. Most, but not all studies, were from the global north. We identified three themes: desired and challenged wellbeing; coping and adaptation; and discrimination and intersectionality. Overall, the studies' findings were varied and reflected different times during the pandemic. Studies reported the impact of mass media messaging and its mostly negative impact on older adults. Many studies highlighted the impact of the COVID-19 pandemic on participants' social connectivity and well-being including missing the proximity of loved ones and in consequence experienced an increase in anxiety, feeling of depression, or loneliness. However, many studies reported how participants adapted to the change of lifestyle including new ways of communication, and social distancing. Some studies focused on discrimination and the experiences of sexual and gender minority and ethnic minority participants. Studies found that the pandemic impacted the participants' well-being including suicidal risk behaviour, friendship loss, and increased mental health issues.

CONCLUSION

The COVID-19 pandemic disrupted and impacted older adults' well-being worldwide. Despite the cultural and socio-economic differences many commonalities were found. Studies described the impact of mass media reporting, social connectivity, impact of confinement on well-being, coping, and on discrimination. The authors suggest that these findings need to be acknowledged for future pandemic strategies. Additionally, policy-making processes need to include older adults to address their needs.

Systematic Review Reporting - Writing concisely and precisely

Systematic reviews rank at the top of the evidence hierarchy. Concise writing implies drafting the systematic review article succinctly, i.e. using as few words to express as full an extent of the research effort as possible. Precise writing means drafting the text with accuracy especially with respect to the methodological and statistical aspects. The Abstract ought to be succinct and structured to allow for editors, peer reviewers and readers to get the gist of the key aspects of the systematic review with a quick read. The readership needs to be able to critically appraisal systematic reviews for their internal and external validity rapidly. The Abstract also needs to be standalone, representing an independent summary that can be fully understood without the need for reading the full paper. The standard structure of the main text of a scientific article called IMRaD (Introduction, Methods, Results and Discussion) applies equally to systematic reviews in the same way as it does to any other kinds of research manuscripts whether related to laboratory experiments or clinical trials. Restricting the word count limits to those imposed by journals may at first seem difficult, even unfair, to systematic reviewers. However, with the availability of online appendices to transparently and fully report the details of the methods, results and other aspects of the work undertaken allows for a succinct print or PDF article. Writing a shorter manuscript is more effortful than writing a longer report. This commentary is aimed at novice systematic reviewers to help them learn the written and unwritten writing rules in order to assist them in producing impactful publications to support evidence-based medicine.

Lessons from farmers' adaptive practices to climate change in China: a systematic literature review

Due to the vulnerability and exposure of agriculture, farmers' adaptive strategies to climate change are important to food security and sustainable environment development. However, a systematic review is still absent, though there are many studies about farmers' adaptations to climate change, and few studies discuss their potential impacts on climate change. This article analyses farmers' adaptation strategies and their heterogeneities across regions in China via a systemic literature review. Then we also discuss possible driving factors of these adaptations and their potential impacts on greenhouse gas emissions. We follow the updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) guidelines to identify and screen publications. A total of 448 relevant records were identified from the Web of Science, Elsevier ScienceDirect, and China National Knowledge Infrastructure (CNKI). We include peer-reviewed publications focusing on farmers engaged in crop farming in China, with survey data and specific adoption ratio analysis of adaptations to climate change. After screening, 27 articles were finally analysed. Our results show that crop variety management, rescheduling farming, increasing production inputs, increasing irrigation, and crop structure management are prevalent strategies reported in the existing literature. However, sustainable adaptations such as improving farmland's ecological environment and agronomic water-saving irrigation gain less attention. Besides, farmers in northern China adapt to climate change more actively compared to their counterparts in southern China. Moreover, some adaptations with high adoption ratios, such as increased chemical inputs, might increase greenhouse gas emissions and accelerate climate change. Our findings have important implications for food security and sustainable agricultural development.

Accuracy and Precision of Consumer-Grade Wearable Activity Monitors for Assessing Time Spent in Sedentary Behavior in Children and Adolescents: Systematic Review

Background

A large number of wearable activity monitor models are released and used each year by consumers and researchers. As more studies are being carried out on children and adolescents in terms of sedentary behavior (SB) assessment, knowledge about accurate and precise monitoring devices becomes increasingly important.

Objective

The main aim of this systematic review was to investigate and communicate findings on the accuracy and precision of consumer-grade physical activity monitors in assessing the time spent in SB in children and adolescents.

Methods

Searches of PubMed (MEDLINE), Scopus, SPORTDiscus (full text), ProQuest, Open Access Theses and Dissertations, DART Europe E-theses Portal, and Networked Digital Library of Theses and Dissertations electronic databases were performed. All relevant studies that compared different types of consumer-grade monitors using a comparison method in the assessment of SB, published in European languages from 2015 onward were considered for inclusion. The risk of bias was estimated using Consensus-Based Standards for the Selection of Health Status Measurement Instruments. For enabling comparisons of accuracy measures within the studied outcome domain, measurement accuracy interpretation was based on group mean or percentage error values and 90% CI. Acceptable limits were predefined as –10% to +10% error in controlled and free-living settings. For determining the number of studies with group error percentages that fall within or outside one of the sides from previously defined acceptable limits, two 1-sided tests of equivalence were carried out, and the direction of measurement error was examined.

Results

A total of 8 studies complied with the predefined inclusion criteria, and 3 studies provided acceptable data for quantitative analyses. In terms of the presented accuracy comparisons, 14 were subsequently identified, with 6 of these comparisons being acceptable in terms of quantitative analysis. The results of the Cochran Q test indicated that the included studies did not share a common effect size (Q₅=82.86; P<.001). I², which represents the percentage of total variation across studies due to heterogeneity, amounted to 94%. The summary effect size based on the random effects model was not statistically significant (effect size=14.36, SE 12.04, 90% CI −5.45 to 34.17; P=.23). According to the equivalence test results, consumer-grade physical activity monitors did not generate equivalent estimates of SB in relation to the comparison methods. Majority of the studies (3/7, 43%) that reported the mean absolute percentage errors have reported values of <30%.

Conclusions

This is the first study that has attempted to synthesize available evidence on the accuracy and precision of consumer-grade physical activity monitors in measuring SB in children and adolescents. We found very few studies on the accuracy and almost no evidence on the precision of wearable activity monitors. The presented results highlight the large heterogeneity in this area of research.
