Patients' experiences of mechanical ventilation in intensive care units in low- and lower-middle-income countries: protocol of a systematic review.

ABSTRACT:

Background

Mechanical ventilation (MV) in intensive care units (ICUs) is a stressful experience for patients. However, these experiences have not been systematically explored in low- and lower-middle-income countries (LLMICs). This systematic review (SR) aims to explore the patients' experiences of MV in ICUs in LLMICs and the factors influencing their experiences.

Methods

The PICO framework will be used to operationalize the review question into key concepts: population (mechanically ventilated adult patients in ICUs), phenomenon of interest (experiences) and context (LLMICs). PubMed, Embase, PsycINFO, CINAHL, Cochrane Library, Scopus and Web of Science will be systematically searched since database inception. Citation, reference list and PubMed-related article searching of included studies will be done to ensure literature saturation. Empirical peer-reviewed literature exploring adult patients' (aged ≥ 18 years) experiences of MV in ICUs in LLMIC will be included. All study designs (quantitative, qualitative and mixed methods) will be included. Two independent reviewers will perform screening, data extraction and critical appraisal. The mixed-methods appraisal tool (MMAT) and Popay's narrative synthesis will be used for critical appraisal and data synthesis, respectively.

Discussion

This SR aims to bridge a gap in knowledge as previous evidence synthesis has described this phenomenon in developed countries. The review design, with the inclusion of quantitative, qualitative and mixed-methods studies, intends to provide a rich and in-depth exploration of the issue. The findings will be presented as themes, subthemes and their explanatory narratives. The gaps in available literature will be identified, and implications of SR findings on policy, practice and future research will be presented. The strength of this SR lies in its systematic, comprehensive, transparent, robust and explicit methodology of identifying, collating, assessing and synthesizing available evidence. By prior registration and reporting of this SR protocol, we aim to ensure transparency and accountability and minimize bias.

Project description:IntroductionCurrent evidence on epidemiology and outcomes of invasively mechanically ventilated intensive care unit (ICU) patients is predominantly gathered in resource-rich settings. Patient casemix and patterns of critical illnesses, and probably also ventilation practices are likely to be different in resource-limited settings. We aim to investigate the epidemiological characteristics, ventilation practices and clinical outcomes of patients receiving mechanical ventilation in ICUs in Asia.Methods and analysisPRoVENT-iMIC (study of PRactice of VENTilation in Middle-Income Countries) is an international multicentre observational study to be undertaken in approximately 60 ICUs in 11 Asian countries. Consecutive patients aged 18 years or older who are receiving invasive ventilation in participating ICUs during a predefined 28-day period are to be enrolled, with a daily follow-up of 7 days. The primary outcome is ventilatory management (including tidal volume expressed as mL/kg predicted body weight and positive end-expiratory pressure expressed as cm H2O) during the first 3 days of mechanical ventilation-compared between patients at no risk for acute respiratory distress syndrome (ARDS), patients at risk for ARDS and in patients with ARDS (in case the diagnosis of ARDS can be made on admission). Secondary outcomes include occurrence of pulmonary complications and all-cause ICU mortality.Ethics and disseminationPRoVENT-iMIC will be the first international study that prospectively assesses ventilation practices, outcomes and epidemiology of invasively ventilated patients in ICUs in Asia. The results of this large study, to be disseminated through conference presentations and publications in international peer-reviewed journals, are of ultimate importance when designing trials of invasive ventilation in resource-limited ICUs. Access to source data will be made available through national or international anonymised datasets on request and after agreement of the PRoVENT-iMIC steering committee.Trial registration numberNCT03188770; Pre-results.

Project description:BackgroundIn the intensive care unit (ICU), critical illness delirium occurs in the context of multiple comorbidities, multi-organ failure, and invasive management techniques, such as mechanical ventilation, sedation, and lack of sleep. Delirium is characterized by an acute confusional state defined by fluctuating mental status, inattention, and either disorganized thinking or an altered level of consciousness. The long-term cognitive and psychosocial function of patients that experience delirium in the ICU is of crucial interest because preliminary data suggest a strong association between ICU-related delirium and long-term cognitive impairment.ObjectiveThe aim of this study is to explore the relationship between delirium in the ICU and adverse outcomes by following mechanically ventilated patients for one year following their discharge from the ICU and collecting data on their long-term cognition and psychosocial function.MethodsThis study will be conducted by enrolling patients in two tertiary ICUs in Australia. We aim to recruit 200 patients who have been mechanically ventilated for more than 24 hours. Data will be collected at the following three time points: (1) at discharge where they will be administered the Mini-Mental State Examination (MMSE); (2) at 6 months after discharge from the ICU discharge where the Impact of Events Scale Revised (IES-R) and the Telephone Inventory for Cognitive Status (TICS) tests will be administered; and (3) at 12 months after discharge from the ICU where the patients will be administered the TICS and IES-R tests, as well as the Informant Questionnaire for Cognitive Decline in the Elderly (IQCODE). The IQCODE will be administered to their "person responsible" or the significant other of the patient.ResultsLong-term cognition and psychosocial function will be the primary outcome of this study. Mortality will also be investigated as a secondary outcome. Active enrollment will take place until the end of September 2016 and data collection will conclude at the end of September 2017. The analysis and results are expected to be available by March 2018.ConclusionDelirium during mechanical ventilation has been linked to longer ICU and hospital stays, higher financial burdens, increased risks of long-term cognitive impairment (ie, dementia), poor functional outcomes and quality of life, and decreased survival. However, delirium during mechanical ventilation in the ICU is not well understood. This study will advance our knowledge of the comprehensive, long-term effects of delirium on cognitive and psychosocial function.Trial registrationAustralian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12616001116415; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=371216 (Archived by WebCite at http://www.webcitation.org/ 6nfDkGTcW).

Project description:IntroductionChild malnutrition continues to be a significant global public health concern. Nutrition-related interventions have changed and diversified over the last two decades, with increasing emphasis on nutrition-sensitive programmes that address underlying determinants of child malnutrition. Cash transfer programmes (CTPs) are used with increasing popularity in lower-income and middle-income countries to improve both food/nutrition insecurity and resilience. Available studies, however, provide mixed findings on the outcomes of CTPs for child nutritional status. This review is the first stage of a research project to develop evidence-informed theories of how CTPs affect child malnutrition. These will be empirically tested in the field and contribute to a better understanding of how, why, for whom and in what circumstances CTPs can be implemented to optimise impacts on child nutritional status.Methods and analysisThis realist review is informed by available standards for realist reviews and follows a five-step process. In step 1, an initial scoping of literature identified potential contextual factors and underlying mechanisms that influence nutritional outcomes, and potential theories developed to address our research question. In step 2, a systematic literature search using multiple databases will be undertaken with papers screened using defined inclusion/exclusion criteria. In step 3, included studies will be appraised, data extracted into a bespoke data extraction tool and used to test and further refine our explanatory framework. The fourth step will synthesise, using a mix of inductive and deductive analytical processes to identify patterns, link chains of inference and tracking and linking of articles. The final step involves dissemination of a preliminary theory for feedback prior to empirically testing it in Kenya and Ethiopia where large-scale CTPs are being implemented.Ethics and disseminationThis review will not involve primary data collection. Findings will be presented in accordance with Realist and Meta-Narrative Evidence Synthesis: Evolving Standards guidelines and published in a peer-reviewed journal.Trial registration numberCRD42018110735.

Project description:ImportanceMany randomized clinical trials (RCTs) led by high-income countries (HICs) now enroll patients from lower middle-income countries (LMICs) and upper middle-income countries (UMICs). Although enrolling diverse populations promotes research collaborations, there are issues regarding which countries participate in RCTs and how this participation may contribute to global research.ObjectiveTo describe which UMICs and LMICs participate in RCTs led by HICs.Design, setting, and participantsA cross-sectional study of all oncology RCTs published globally during January 1, 2014, to December 31, 2017, was conducted. The study cohort was restricted to RCTs led by HICs that enrolled participants from LMICs and UMICs. Study analyses were conducted in November 1, 2021, to May 31, 2022.Main outcomes and measuresA bibliometric approach (Web of Science 2007-2017) was used to explore whether RCT participation was proportional to other measures of cancer research activity. Participation in RCTs (ie, percentage of RCTs in the cohort in which each LMIC and UMIC participated) was compared with country-level cancer research bibliometric output (ie, percentage of total cancer research bibliometric output from the same group of countries that came from a specific LMIC and UMIC).ResultsAmong the 636 HIC-led RCTs, 186 trials (29%) enrolled patients in LMICs (n = 84 trials involving 11 LMICs) and/or UMICs (n = 181 trials involving 26 UMICs). The most common participating LMICs were India (42 [50%]), Ukraine (39 [46%]), Philippines (23 [27%]), and Egypt (12 [14%]). The most common participating UMICs were Russia (115 [64%]), Brazil (94 [52%]), Romania (62 [34%]), China (56 [31%]), Mexico (56 [31%]), and South Africa (54 [30%]). Several LMICs are overrepresented in the cohort of RCTs based on proportional cancer research bibliometric output: Ukraine (46% of RCTs but 2% of cancer research bibliometric output), Philippines (27% RCTs, 1% output), and Georgia (8% RCTs, 0.2% output). Overrepresented UMICs include Russia (64% RCTs, 2% output), Romania (34% RCTs, 2% output), Mexico (31% RCTs, 2% output), and South Africa (30% RCTs, 1% output).Conclusions and relevanceIn this cross-sectional study, a substantial proportion of RCTs led by HICs enrolled patients in LMICs and UMICs. The LMICs and UMICs that participated in these trials did not match overall cancer bibliometric output as a surrogate for research ecosystem maturity. Reasons for this apparent discordance and how these data may inform future capacity-strengthening activities require further study.
