    Identification of Key Factors for Optimized Healthcare Services: A Protocol for a Multi-phase Study of the Dubai Vaccination Campaign
    (2022) Faroun, Hayette; Zary, Nabil; Gad, Kareem; Al Suwaidi, Hanan
    Background: Mass vaccination of the global population against the novel coronavirus (COVID-19) posed multiple challenges, including effectively administering millions of doses in a short period of time while ensuring public safety and accessibility. The Government of Dubai launched a mass campaign in December 2020 to vaccinate all its citizens and residents, targeting the population over the age of 18 against COVID-19. The vaccination campaign involved a transformation of multiple commercial spaces into mass vaccination centers (MVCs) across the city of Dubai, the largest of which was the Dubai One Central (DOC) Vaccination Center. It was operational between 17 January 2021 and 27 January 2022. Objective: The multi-phase research study aims to empirically explore the opinions of multiple healthcare stakeholders, elicit the key success factors that can influence the effective delivery of emergency healthcare services such as COVID-19 MVCs, and explore how these factors relate to one another. Method: To understand more about the operations of the Dubai One Central vaccination center, the study follows a multi-phase design divided into two main sections. The study is conducted by the Institute for Excellence in Health Professions Education (ieHPE) at Mohammed Bin Rashid University of Medicine and Health Sciences (MBRU) between December 2021 and January 2023. To elicit the key success factors that contributed to the vaccination campaign administered at DOC, the research team conducted 30 semi-structured interviews (SSI) with a sample of staff and volunteers who worked at the DOC vaccination center. Stratified random sampling was used to select the participants, and the interview cohort included representatives from the management team, team leaders, administration and registration team, vaccinators, and volunteers. A total of 103 people were invited to take part in the research study and 30 people accepted to participate in the SSI interviews. To validate the participation of various stakeholders, the second phase analytically investigated one’s subjectivity through Q-methodology and empirically investigating the opinions obtained from the research participants during phase 1. Results: As of July 2022, 30 semi-structured interviews were conducted with the research participants. The expected results from the project's first phase will be the identification of key success factors, enablers, and barriers of the design and operation of the Covid-19 vaccination center at DOC. While the expected results from the study's second phase will identify patterns of similarities and differences in the ranking of the Q-sets. The final set of results from this dataset will quantitatively interpret the common answers amongst participants and the correlation between the selected success factors relating to the study. Conclusions: The study will provide a comprehensive two-phase approach to obtaining the key success factors that can influence the delivery of high-quality healthcare services such as emergency services launched during a global pandemic. The study's findings will be translated into key factors that could support designing future healthcare services utilizing evidence-based practice. In line with future plans, a study will use data, collected through the One Central vaccination center, to develop a simulation model outlining the process of the customer journey and center workflow.

    Validation and psychometric evaluation of the Arabic Adult Vaccine Hesitancy Scale
    (2025-12) Nour, Radwa; Powell, Leigh; Sleibi, Randa; Zary, Nabil; Al Suwaidi, Hanan
    Vaccine hesitancy is one of the top ten global health threats, with a culturally adapted, validated tool being essential for accurately measuring it to guide public health interventions. Although translations of the Adult Vaccine Hesitancy Scale (aVHS) to local languages and their validation have occurred in several contexts, no validated Arabic version exists for the Middle East population. This, however, impedes the process of generating locally and regionally reflective data for targeted interventions and evaluation of vaccine outreach efforts. To translate and validate the Adult Vaccine Hesitancy Scale (aVHS) for Arabic-speaking adults. This cross-sectional study followed a five-phase process: translation, expert review, preliminary testing, pilot testing, and validation with psychometric analysis. Translation and back translation were conducted then reviewed by an expert committee. The approved version of the Arabic aVHS (Ar-aVHS) was tested against the English version (E-aVHS) on 50 participants and demonstrated excellent internal consistency (Ar-aVHS Cronbach's α = 0.8699). The overall correlation between Arabic and English scale scores was strong (Spearman's rho = 0.8418,  < .001). During pilot phase on 1000 participants, the Ar-aVHS demonstrated adequate internal consistency (Cronbach's α = 0.636 overall). Exploratory factor analysis supported a two-factor structure, confidence in vaccines and risk perception, both explaining 40.5% of total variance. Using the established cutoff score, 66.2% of participants were classified as vaccine hesitant. The results of the study suggest that the Ar-aVHS is a valid, culturally relevant, and psychometrically sound instrument for assessing vaccine hesitancy among Arabic-speaking adults.
