Barriers and facilitators to the conduct of critical care research in low and lower-middle income countries: A scoping review

Stroke risk prediction models: A systematic review and meta-analysis

BACKGROUND

Prediction algorithms/models are viable methods for identifying individuals at high risk of stroke across diverse populations for timely intervention. However, evidence summarizing the performance of these models is limited. This study examined the performance and weaknesses of existing stroke risk-score-prediction models (SRSMs) and whether performance varied by population and region.

METHODS

PubMed, EMBASE, and Web of Science were searched for articles on SRSMs from the earliest records until February 2022. The Prediction Model Risk of Bias Assessment Tool was used to assess the quality of eligible articles. The performance of the SRSMs was assessed by meta-analyzing C-statistics (0 and 1) estimates from identified studies to determine the overall pooled C-statistics by fitting a linear restricted maximum likelihood in a random effect model.

RESULTS

Overall, 17 articles (cohort study = 15, nested case-control study = 2) comprising 739,134 stroke cases from 6,396,594 participants from diverse populations/regions (Asia; n = 8, United States; n = 3, and Europe and the United Kingdom; n = 6) were eligible for inclusion. The overall pooled c-statistics of SRSMs was 0.78 (95%CI: 0.75, 0.80; I2 = 99.9%), with most SRSMs developed using cohort studies; 0.78 (95%CI: 0.75, 0.80; I2 = 99.9%). The subgroup analyses by geographical region: Asia [0.81 (95%CI: 0.79, 0.83; I2 = 99.8%)], Europe and the United Kingdom [0.76 (95%CI: 0.69, 0.83; I2 = 99.9%)] and the United States only [0.75 (95%CI: 0.72, 0.78; I2 = 73.5%)] revealed relatively indifferent performances of SRSMs.

CONCLUSION

SRSM performance varied widely, and the pooled c-statistics of SRSMs suggested a fair predictive performance, with very few SRSMs validated in independent population group(s) from diverse world regions.

Barriers to Decolonizing Global Health: Identification of Research Challenges Facing Investigators Residing in Low- and Middle-Income Countries

The practice of global health is plagued by power structures favoring high-income countries. Efforts to decolonize global health must consider the systemic limitations that LMIC investigators face at local, national, and international levels.

National ICU Registries as Enablers of Clinical Research and Quality Improvement

OBJECTIVES

Clinical quality registries (CQRs) have been implemented worldwide by several medical specialties aiming to generate a better characterization of epidemiology, treatments, and outcomes of patients. National ICU registries were created almost 3 decades ago to improve the understanding of case-mix, resource use, and outcomes of critically ill patients. This narrative review describes the challenges, proposed solutions, and evidence generated by National ICU registries as facilitators for research and quality improvement.

DATA SOURCES

English language articles were identified in PubMed using phrases related to ICU registries, CQRs, outcomes, and case-mix.

STUDY SELECTION

Original research, review articles, letters, and commentaries, were considered.

DATA EXTRACTION

Data from relevant literature were identified, reviewed, and integrated into a concise narrative review.

DATA SYNTHESIS

CQRs have been implemented worldwide by several medical specialties aiming to generate a better characterization of epidemiology, treatments, and outcomes of patients. National ICU registries were created almost 3 decades ago to improve the understanding of case-mix, resource use, and outcomes of critically ill patients. The initial experience in European countries and in Oceania ensured that through locally generated data, ICUs could assess their performances by using risk-adjusted measures and compare their results through fair and validated benchmarking metrics with other ICUs contributing to the CQR. The accomplishment of these initiatives, coupled with the increasing adoption of information technology, resulted in a broad geographic expansion of CQRs as well as their use in quality improvement studies, clinical trials as well as international comparisons, and benchmarking for ICUs.

CONCLUSIONS

ICU registries have provided increased knowledge of case-mix and outcomes of ICU patients based on real-world data and contributed to improve care delivery through quality improvement initiatives and trials. Recent increases in adoption of new technologies (i.e., cloud-based structures, artificial intelligence, machine learning) will ensure a broader and better use of data for epidemiology, healthcare policies, quality improvement, and clinical trials.

Are open access article processing charges affordable for otolaryngologists in low-income and middle-income countries?

PURPOSE OF REVIEW

Open access articles are more frequently read and cited, and hence promote access to knowledge and new advances in healthcare. Unaffordability of open access article processing charges (APCs) may create a barrier to sharing research. We set out to assess the affordability of APCs and impact on publishing for otolaryngology trainees and otolaryngologists in low-income and middle-income countries (LMICs).

RECENT FINDINGS

A cross-sectional online survey was conducted among otolaryngology trainees and otolaryngologists in LMICs globally. Seventy-nine participants from 21 LMICs participated in the study, with the majority from lower middle-income status (66%). Fifty-four percent were otolaryngology lecturers while 30% were trainees. Eighty-seven percent of participants received a gross monthly salary of less than USD 1500. Fifty-two percent of trainees did not receive a salary. Ninety-one percent and 96% of all study participants believed APCs limit publication in open access journals and influence choice of journal for publication, respectively. Eighty percent and 95% believed APCs hinder career progression and impede sharing of research that influences patient care, respectively.

SUMMARY

APCs are unaffordable for LMIC otolaryngology researchers, hinder career progression and inhibit the dissemination of LMIC-specific research that can improve patient care. Novel models should be developed to support open access publishing in LMICs.

Model for enhancing the research conducted by the university medical staff: Participatory action research

This study employed mixed methods with a participatory action research approach to explore factors currently undermining the conduction of research and to develop strategies to boost research productivity. A questionnaire was distributed to 64 staff members of the Department of Anesthesiology at a university-based hospital. Thirty-nine staff members (60.9%) gave informed consent and responses. Staff views were also collected through focus group discussions. The staff reported that limited research methodology skills, time management, and complex managerial processes were the limitations. Age, attitudes, and performance expectancy were significantly correlated with research productivity. A regression analysis demonstrated that age and performance expectancy significantly influenced research productivity. A Business Model Canvas (BMC) was implemented to gain insight into the goal of enhancing the conduct of research. Business Model Innovation (BMI) established a strategy to improve research productivity. The concept, comprising personal reinforcement (P), aiding systems (A), and a lifting-up of the value of research (L), the PAL concept, was considered key to enhancing the conduct of research, with the BMC providing details and integrating with the BMI. To upgrade the research performance, the involvement of management is imperative, and future action will involve the implementation of a BMI model to increase research productivity.

Barriers and Facilitators to Conducting Oncology Clinical Trials in the UAE

Cancer research and clinical trials are essential to improve cancer patients' outcomes and advance the oncology field. The United Arab Emirates (UAE) has been lagging in cancer research with many barriers, including healthcare, institutional, regulatory, patient and community, the global oncology community, and the pharmaceutical industry. In this report, we try to address these challenges from our perspective. Making clinical trials accessible for cancer patients in the UAE requires a collaborative approach from all stakeholders and serious consideration for the greater cause to improve the patient's outcome and contribute to the advancement of the cancer field worldwide. There has been significant support from the UAE government and the regulators in the UAE to facilitate and encourage research in general and cancer research in particular with recent initiatives and international collaborations. Private and public institutions must overcome their competitive moods and work together to strengthen the research network across the UAE and improve accrual for potential clinical trials. Public awareness and education must overcome long-standing perceptions about research and clinical trials in the UAE. The pharmaceutical industry must work closely with institutions across the UAE and support them in establishing accredited research programs and clinical trial units. The Emirates Oncology Society is establishing the Oncology Research Working Group to advocate and advance cancer research in the UAE. All stakeholders must be engaged to successfully implement impactful clinical trials in the UAE and the region.

The research environment of critical care in three Asian countries: A cross-sectional questionnaire survey

Although inadequate research support for intensivists can be one major reason of the poor research productivity, no study has investigated the current research environment in critical care medicine in Asia. The objective of this study was to describe Asian academia in critical care from the research environment perspective. We conducted a cross-sectional questionnaire survey targeting all physician members of the Societies of Intensive/Critical Care Medicine in Japan, South Korea, and Singapore. We collected the characteristics of the participants and their affiliated institutions and the research environment. The outcome was the number of peer-reviewed publications. Multivariable logistic regression analyses examined the association between the outcome and the following five research environmental factors (i.e., country of the respondents, availability of secured time for research activities or research supporting staff for the hospital, practice at a university-affiliated hospital, and years of clinical practice of 10 years or longer). Four hundred ninety responded (overall response rate: 5.6%) to the survey between June 2019 and January 2020. Fifty-five percent worked for a university-affiliated hospital, while 35% worked for a community hospital. Twenty-four percent had secured time for research within their full-time work hours. The multivariable logistic model found that a secured time for the research activities [odds ratio (OR): 2.77; 95% confidence interval (CI), 1.46–5.24], practicing at a university-affiliated hospital (OR: 2.61; 95% CI, 1.19–5.74), having clinical experience of 10 years or longer (OR:11.2; 95%CI, 1.41–88.5), and working in South Korea (OR: 2.18; 95% CI, 1.09–4.34, Reference: Japan) were significantly associated with higher research productivity. Intensivists in the three countries had limited support for their research work. Dedicated time for research was positively associated with the number of research publications.
