Quantitizing findings from qualitative studies for integration in mixed methods reviewing

Using qualitative comparative analysis as a mixed methods synthesis in systematic mixed studies reviews: Guidance and a worked example

Qualitative comparative analysis (QCA) is a hybrid method designed to bridge the gap between qualitative and quantitative research in a case-sensitive approach that considers each case holistically as a complex configuration of conditions and outcomes. QCA allows for multiple conjunctural causation, implying that it is often a combination of conditions that produces an outcome, that multiple pathways may lead to the same outcome, and that in different contexts, the same condition may have a different impact on the outcome. This approach to complexity allows QCA to provide a practical understanding for complex, real-world situations, and the context of implementing interventions. There are guides for conducting QCA in primary research and quantitative systematic reviews yet, to our knowledge, no guidance for conducting QCA in systematic mixed studies reviews (SMSRs). Thus, the specific objectives of this paper are to (1) describe a step-by-step approach for novice researchers for using QCA to integrate qualitative and quantitative evidence, including guidance on how to use software; (2) highlight specific challenges; (3) propose potential solutions from a worked example; and (4) provide recommendations for reporting.

Fear of falling from the perspective of affected persons-A systematic review and qualitative meta-summary using Sandelowski and Barroso's method

BACKGROUND

Fear of falling (FoF) affects a large number of older people, whether they have a history of falls or not. This has an impact on their lives. FoF is a potentially modifiable factor, which has been identified as one of the most important threats to older people's autonomy.

OBJECTIVES

To gain a comprehensive understanding of the phenomenon, we conducted a systematic review and meta-summary. The available evidence from qualitative research exploring how people experience FoF and how FoF affects daily living was aggregated.

METHODS

We followed the approach by Sandelowski and Barroso (2007) as a method to aggregate knowledge based on an exhaustive literature search. We searched the databases CINAHL, MEDLINE, PsycINFO and SSCI systematically for relevant articles as well as grey literature until September 2020. Out of the included studies, findings were extracted, edited, grouped and abstracted into meta-findings. Finally, the manifest frequency effect size of each abstracted meta-finding was calculated.

RESULTS

Out of 2978 identified studies, 15 met our inclusion criteria, which were published between 1993 and 2017 and included a total of 276 participants. We extracted 578 findings, and the abstraction process resulted in 183 meta-findings. We identified three main topics: 'Triggers and reasons for FoF identified by affected people', 'Consequences attributed to FoF' and 'Strategies to manage FoF in daily life'.

CONCLUSION

Our findings demonstrate that FoF has a far-reaching impact on the lives of those affected. With the aggregation of the existing qualitative data with the application of the frequency effect size, we were able to identify three areas of particular importance to those affected: (1) controlling the risk, (2) creating a safe environment and (3) staying independent. Implications for practice these three areas of particular importance to those affected should be taken into account when revisiting or creating new interventions to prevent or reduce FoF.

Caregivers' experiences and perspectives on caring for the elderly during the COVID-19 pandemic: A qualitative systematic review

AIMS

The goal of this study was to explore caregivers' experiences, perspectives, emotions, knowledge and needs in caring for older people during the COVID-19 pandemic. These included, but were not limited to, experiences in hospital care, home care and nursing home care.

BACKGROUND

Because of the high mortality rate associated with the COVID-19 pandemic, senior care is critical. During the COVID-19 pandemic, caregivers caring for older people have had unique experiences potentially affecting the quality of care provided. This topic has received substantial attention since the start of the pandemic and has been studied by numerous researchers. However, experiences may differ among countries and time periods. In addition, no qualitative systematic reviews on this topic appear to have been published.

EVALUATION

In this systematic review of qualitative studies, data were collected from the following electronic databases: PubMed, Web of Science, Scopus, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Science Direct and PsycINFO. Titles and abstracts were screened according to the inclusion and exclusion criteria, full texts were screened and the methodological quality of included studies was assessed with the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research by two independent reviewers.

KEY ISSUE(S)

A total of 141 findings were extracted and aggregated into 20 categories; 6 synthesized findings were identified.

CONCLUSION

This review indicates caregivers' experiences and perceptions regarding caring for older people during the COVID-19 pandemic. The results of a qualitative systematic review show that caregivers' emotions, cognitions and knowledge have affected the quality of caregivers' senior care services during the pandemic. Caregivers caring for older adults should practise self-awareness, understanding their knowledge and attitudes to improve the quality of senior care. Moreover, health care administrators and policymakers should make concerted efforts to cultivate a better working environment.

IMPLICATIONS FOR NURSING MANAGEMENT

Managers should formulate timely and effective management strategies. During the COVID-19 pandemic, the workload of caregivers has increased, thus requiring better scheduling by managers. Furthermore, managers should consider the negative emotions of caregivers and prevent negative emotions from affecting their work. Besides, virtual technology should be applied to senior care and psychological support be provided for caregivers in this special care setting.

Patients' experiences of delirium: A systematic review and meta-summary of qualitative research

AIMS

The purpose of this systematic review and meta-summary was the aggregation of the empirical qualitative literature on patients' experiences of delirium in order to support the development and implementation of patient-oriented delirium management and to guide future research.

DESIGN

We conducted a systematic literature review of qualitative research published between January 1980 and June 2019.

DATA SOURCES

In June 2019, we searched in Medline, CINAHL, SSCI and PsycInfo to identify relevant reports. In addition, we conducted searches in three dissertation databases (BASE, DART and ProQuest) and Google Scholar.

REVIEW METHODS

We used methods developed by Sandelowski and Barroso to construct a meta-summary of the findings by extracting them from the reports, abstracting them into meta- findings and calculating their manifest interstudy frequency effect sizes.

RESULTS

Out of the 742 identified records, 24 reports based on delirium experience accounts of 483 patients met our criteria and were included. One thousand ninety-seven findings were extracted from these reports and abstracted into 92 meta-findings. These were grouped to the five emerging themes 'perception', 'emotions', 'interaction with others', 'dealing with delirium' and 'influence on further life'.

CONCLUSION

Delirium is commonly perceived as an overall distressing condition, which can accompany and influence patients even after hospital discharge.

IMPACT

This systematic review and meta-summary is the most comprehensive aggregation of qualitative research of the patient delirium experience to date. It allows us to better understand, extract meaning from, and weigh the qualitative findings in their context by calculating their manifest frequency effect sizes. This can be used to support the development and implementation of delirium management concepts.

Grandparental dietary provision, feeding practices and feeding styles when caring for preschool-aged grandchildren: A systematic mixed methods review

Grandparents are frequently relied upon to care for their preschool-aged grandchildren. These early years are a crucial age in the development of dietary habits and preferences. This review aims to determine grandparental dietary provision, feeding practices and feeding styles when caring for their preschool-aged grandchildren. Medline, PsycInfo and Web of Science were searched in January 2020. A systematic mixed methods approach was used to synthesize the qualitative (n = 13) and quantitative (n = 7) articles describing grandparents' feeding styles (n = 9), feeding practices (n = 14) and dietary provision (n = 18). Grandparents are serving large portion sizes and encouraging their grandchildren to eat frequently. Results are mixed for the types of foods provided; grandparents provide discretionary foods high in sugar and fat, and some also choose more expensive core foods as treats (e.g., berries). Grandparents engage in feeding practices that promote healthy eating (e.g., creating a healthy feeding environment) and promote autonomy and independence (e.g., considering their grandchild's preferences). However, they also use some coercive feeding practices (e.g., using food as a reward) and may be using indulgent feeding styles, which can be conducive to obesogenic dietary intakes. Interventions targeting grandparents could be an effective way to improve dietary-related health outcomes in young children.

Quantitizing findings from qualitative studies for integration in mixed methods reviewing

In mixed methods reviewing, data from quantitative and qualitative studies are combined at the review level. One possible way to combine findings of quantitative and qualitative studies is to quantitize qualitative findings prior to their incorporation in a quantitative review. There are only a few examples of the quantification of qualitative findings within this context. This study adds to current research on mixed methods review methodology by reporting the pilot implementation of a new four‐step quantitizing approach. We report how we extract and quantitize the strength of relationships found in qualitative studies by assigning correlations to vague quantifiers in text fragments. This article describes (a) how the analysis is prepared; (b) how vague quantifiers in text fragments are organized and transformed to numerical values; (c) how qualitative studies as a whole are assigned effect sizes; and (d) how the overall mean effects size and variance can be calculated. The pilot implementation shows how findings from 26 primary qualitative studies are transformed into mean effect sizes and corresponding variances.
