Climate change and HIV are interconnected epidemics that increase vulnerability in people living with HIV (PLWH), particularly in sub-Saharan Africa. Despite their public health significance, research on the synergistic effects of these epidemics on the health of PLWH is limited. The advancement of non-invasive wearable technology offers an opportunity to leverage objective health data for large-scale research, addressing this knowledge gap. This study will examine the impact of weather events on distinct health variables of PLWH within the Siaya Health and Demographic Surveillance System (HDSS) in rural Kenya.

Over a period of 6 months, we continuously monitored health parameters of a total of 200 participants including heart rate, activity and sleep, using consumer-grade wearable devices. We will correlate these health data with real-time weather parameters (ambient temperature, wet bulb globe temperature, precipitation level) from five weather stations within the HDSS area and compare between HIV-positive participants and an HIV-negative control group. Additionally, a convergent mixed-methods approach will explore participants’ perceptions of the impact of weather events on their health and personal experiences. The study aims to inform future research on the complex relationship between HIV and weather events, which are projected to increase in frequency in this region due to climate change and provide valuable insights for policymakers to develop effective measures to protect this vulnerable population amid the growing climate crisis.

This study has been approved by the Research Ethics Committees at Kenya Medical Research Institute, Nairobi (approved on 23 October 2023; SERU 4826) and Heidelberg University Hospital, Germany (approved on 14 February 2023; S-824/2022). Written informed consent was obtained from all participants prior to enrolment, with data anonymised and handled according to Kenyan and German data protection regulations. Research findings will be disseminated through peer-reviewed publications and presented at scientific conferences.

Patients with frailty are at risk of adverse outcomes such as mortality, falls, deconditioning and hospital readmissions. With an increasingly ageing population and a greater likelihood of frailty, there is a significant need to ensure that patients are managed in the right place and at the right time. There has been a focus on offering hospital-level care at home as a way to meet this need, incorporating strategies to integrate care and use digital solutions. Digital twin (DT) technology is one advancement, offering a virtual replica of an object/environment, which has the potential to make use of real-time data personalised for an individual patient and/or setting to inform and support patient management decisions. We are yet to realise the full potential of this new way of integrated working and technological advancements. This scoping review aims to ascertain the current evidence for the components of the DT architecture to enable the monitoring and management of patients with frailty living at home.

This scoping review will follow the Joanna Briggs Institute methodology for scoping reviews and will be reported following the Preferred Reporting Items for Systematic Reviews Extension for Scoping Reviews guidelines. The following electronic databases will be searched: Medline, Embase, CINAHL, Cochrane CENTRAL, Web of Science and Scopus. Relevant websites will be searched for grey literature or case reports to capture the required information, as well as any documents provided by stakeholders. Primary studies, published in the English language from 2019 to the present day, which report on the monitoring or management of patients with long-term conditions and frailty within their home environment, will be included. Screening will be conducted by at least two independent reviewers against eligibility criteria, and a piloted data extraction form will be used to align with the research questions. Qualitative content analysis will be used. Data will be presented in tabular form, as well as descriptive and illustrative formats, to address the objectives of this review.

This scoping review does not require ethical approval. The findings of this review will be disseminated through peer-reviewed journals and conferences and will support the development of a conceptual model of a hospital-at-home DT for the management of patients with frailty.
