To assess the preliminary effectiveness and cost-effectiveness of a culturally tailored, music-based broadcast intervention delivered through schools and community radio to improve referral adherence among schoolchildren to inform the need for a definitive trial.

Pilot randomised interventional study.

18 schools across Unguja and Pemba islands, Zanzibar.

Schoolchildren (6–18 years old) who failed vision screening and were referred for care recruited from January to February 2024. The registered sample size reflects the full cohort, including children and adults. This manuscript reports on the child cohort only, as per the predefined analysis plan.

Group 1 received 3 months of school-based broadcasts of culturally tailored 3–6 min songs (played three times daily on 2 days per week), followed by 3 months of community radio broadcasts of additional songs (3–6 min, aired three times daily); Group 2 received the community broadcasts during the same period as Group 1.

The primary outcome was change in referral adherence assessed at two time points: 3 months after school broadcast and 3 months after community broadcast, expressed in difference-in-difference estimates and effect sizes. Secondary outcomes included reporting of adverse events and contamination, and cost-effectiveness calculated as cost per child reached and cost per referred child accessed care in study groups and combined intervention.

374 children were referred to eye care services, including 246 in Group 1 and 128 in Group 2. Referral adherence was 69.8% in Group 1 and 42.9% in Group 2 (p=0.0006). The school broadcast phase yielded an effect size of 0.26 and a cost of US$4.65 per referred child accessing services. The community broadcast produced an effect size of 0.21, with a cost of US$0.29 per person reached. The combined intervention reached individuals at a cost of US$0.37 per person. No adverse event and contamination was reported.

A combined school and community broadcast intervention improved referral adherence in this pilot trial, with evidence of cost-effectiveness. These findings support the conduct of a fully powered definitive trial.

Our aim is to develop a Framework of Measurement for people living with Long COVID and their caregivers for use in Long COVID research and clinical practice. Specifically, we will characterise evidence pertaining to outcome measurement and identify implementation considerations for use of outcome measures among adults and children living with Long COVID and their caregivers.

We will conduct a scoping study involving: (1) an evidence review and (2) a two-phased consultation, using methodological steps outlined by the Arksey and O’Malley Framework and Joanna Briggs Institute. We will answer the following question: What is known about outcome measures used to describe, evaluate or predict health outcomes among adults and children living with Long COVID and their caregivers? Evidence review: we will review peer review published and grey literature to identify existing outcome measures and their reported measurement properties with people living with Long COVID and their caregivers. We will search databases including MEDLINE, Embase, CINAHL, PsycINFO and Scopus for articles published since 2020. Two authors will independently review titles and abstracts, followed by full text to select articles that discuss or use outcome measures for Long COVID health outcomes, pertain to adults or children living with Long COVID and/or their caregivers and are based in research or clinical settings. We will extract data including article characteristics, terminology and definition of Long COVID, health outcomes assessed, characteristics of outcome measures, measurement properties and implementation considerations. We will collate and summarise data to establish a preliminary Framework of Measurement. Consultation phase 1: we will conduct an environmental scan involving a cross-sectional web-based questionnaire among individuals with experience using or completing outcome measures for Long COVID, to identify outcome measures not found in the evidence review and explore implementation considerations for outcome measurement in the context of Long COVID. Consultation phase 2: we will conduct focus groups to review the preliminary Framework of Measurement and to highlight implementation considerations for outcome measurement in Long COVID. We will analyse questionnaire and focus group data using descriptive and content analytical approaches. We will refine the Framework of Measurement based on the focus group consultation using community-engaged approaches with the research team.

Protocol approved by the University of Toronto Health Sciences Research Ethics Board (protocol #46503) for the consultation phases of the study. Outcomes will include a Framework of Measurement, to enhance measurement of health outcomes in Long COVID research and clinical practice. Knowledge translation will also occur in the form of publications and presentations.
