Learning from public health practice: the development of a library of community-centered practice examples.

BACKGROUND: Valuable learning derived from public health practice can be captured through practice-based case studies, also known as practice examples. Practice examples of participatory interventions supplement the evidence base by providing information on the complexities of implementation in communities. This paper reports on a Public Health England project to build a bank of community-centered practice examples based on robust processes of collection and curation. METHODS: The multidisciplinary project had three phases: (i) development and piloting a process to collect practice examples, (ii) refining review processes and gathering further examples via national and regional teams (iii) maintenance of an accessible collection on the library platform. RESULTS: The project resulted in a searchable collection of 55 practice examples illustrating participatory approaches in public health practice. The collection shows diversity in terms of settings, population, focus and type of approach used to work with communities. A secondary outcome was the development of generic guidance and templates for further collections on public health topics. CONCLUSIONS: This project illustrates how information on the implementation of community-centered approaches in real-life contexts can be gathered and disseminated through a transferable process. Having collections of practice examples supports knowledge exchange in public health as learning is shared.

Effectiveness of digital interventions to improve household and community infection prevention and control behaviours and to reduce incidence of respiratory and/or gastro-intestinal infections: a rapid systematic review.

BACKGROUND: Digital interventions have potential to efficiently support improved hygiene practices to reduce transmission of COVID-19. OBJECTIVE: To evaluate the evidence for digital interventions to improve hygiene practices within the community. METHODS: We reviewed articles published between 01 January 2000 and 26 May 2019 that presented a controlled trial of a digital intervention to improve hygiene behaviours in the community. We searched MEDLINE, Embase, PsycINFO, Cochrane Controlled Register of Trials (CENTRAL), China National Knowledge Infrastructure and grey literature. Trials in hospitals were excluded, as were trials aiming at prevention of sexually transmitted infections; only target diseases with transmission mechanisms similar to COVID-19 (e.g. respiratory and gastrointestinal infections) were included. Trials had to evaluate a uniquely digital component of an intervention. Study designs were limited to randomised controlled trials, controlled before-and-after trials, and interrupted time series analyses. Outcomes could be either incidence of infections or change in hygiene behaviours. The Risk of Bias 2 tool was used to assess study quality. RESULTS: We found seven studies that met the inclusion criteria. Six studies reported successfully improving self-reported hygiene behaviour or health outcomes, but only one of these six trials, Germ Defence, confirmed improvements using objective measures (reduced consultations and antibiotic prescriptions). Settings included kindergartens, workplaces, and service station restrooms. Modes of delivery were diverse: WeChat, website, text messages, audio messages to mobiles, electronic billboards, and electronic personal care records. Four interventions targeted parents of young children with educational materials. Two targeted the general population; these also used behaviour change techniques or theory to inform the intervention. Only one trial had low risk of bias, Germ Defence; the most common concerns were lack of information about the randomisation, possible bias in reporting of behavioural outcomes, and lack of an analysis plan and possible selective reporting of results. CONCLUSION: There was only one trial that was judged to be at low risk of bias, Germ Defence, which reduced incidence and severity of illness, as confirmed by objective measures. Further evaluation is required to determine the effectiveness of the other interventions reviewed. TRIAL REGISTRATION: PROSPERO CRD42020189919 .
