- Objectives: enhancing uptake of COVID-19 vaccines is an important tool for managing the pandemic. However, in Hong Kong, the COVID-19 vaccination rate in the general population was unsatisfactory during the early phase of the vaccination program. This two-part study aimed to (i) identify barriers and facilitators to receiving vaccinations, and (ii) develop theoretically-informed implementation strategies for promoting uptake. Methods: in part 1, 45 Hong Kong residents who differed in their willingness to vaccinate (willing (n = 15), were unwilling (n = 15), and were hesitant (n = 15)), were interviewed individually in February 2021. They were invited to express their perceptions of receiving the COVID-19 vaccination. The theoretical domains framework (TDF) was applied to guide the interviews and analyses. Behavioral diagnoses from these findings were then used to develop theoretically-informed implementation strategies in part 2, composed of behavior change techniques (BCTs) informed by the established BCT taxonomy. Results: in part 1, the five main barriers were (i) concerns on severe and long-term side effects; (ii) low confidence in the safety and effectiveness due to concerns of their accelerated development; (iii) unclear information on logistical arrangements of the vaccination program; (iv) insufficient data on safety and effectiveness; and (v) perceived low protection ability conferred by the vaccines. The five main facilitators included (i) healthcare professionals recommendations; (ii) news from TV, radio, and newspapers as main sources of trustworthy information; (iii) vaccine-related health education delivered by healthcare professionals; (iv) expectations of resuming to a normal social life; and (v) perceived benefits outweighing risks of mild and short-term side effects. Conclusions: seven implementation strategies were developed in part 2 based on the results above, namely (i) providing trustworthy vaccine-related information and scaling up the promotion; (ii) encouraging healthcare professionals to recommend vaccinations; (iii) giving incentives; (iv) using social influence approaches; (v) allowing a selection of COVID-19 vaccine brands; (vi) increasing accessibility for vaccinations; and (vii) emphasizing social responsibility.

- Chronic kidney disease (CKD) is responsible for a public health burden with multi-systemic complications. Through transancestry meta-analysis of genome-wide association studies of estimated glomerular filtration rate (eGFR) and independent replication (n = 1,046,070), we identified 264 associated loci (166 new). Of these,147 were likely to be relevant for kidney function on the basis of associations with the alternative kidney function marker blood urea nitrogen (n = 416,178). Pathway and enrichment analyses, including mouse models with renal phenotypes, support the kidney as the main target organ. A genetic risk score for lower eGFR was associated with clinically diagnosed CKD in 452,264 independent individuals. Colocalization analyses of associations with eGFR among 783,978 European-ancestry individuals and gene expression across 46 human tissues, including tubulo-interstitial and glomerular kidney compartments, identified 17 genes differentially expressed in kidney. Fine-mapping highlighted missense driver variants in 11 genes and kidney-specific regulatory variants. These results provide a comprehensive priority list of molecular targets for translational research.

- Background: Avoidable hospital readmission is a major problem among health systems. Although there are effective peri-discharge interventions for reducing avoidable hospital readmission, successful implementation is challenging. This systematic review(SR) of qualitative studies aimed to identify barriers and facilitators to implementing peri-discharge interventions from providers and service users perspectives.Methods: We searched four databases for potentially eligible qualitative studies from databases inception to Mar 2020, and updated literature search for studies published between 2020 to Oct 2021. Barriers and facilitators to implementing peri-discharge interventions were identified and mapped onto the Consolidated Framework for Implementation Research(CFIR) constructs. Inductive analysis of the CFIR constructs was performed to yield thematic areas that illustrated the relationship between various facilitators and barriers, generating practical insights to key implementation issues. Results: Thirteen qualitative studies were included in this SR. Key issues were clustered in the CFIR constructs of Design Quality and Complexity of the intervention, strength of Network and Communication, being responsive to Patient Needs with sufficient Resource support, and External Incentives. The three thematic areas were rationality of the interventions, readiness and effort of multidisciplinary implementation teams, and influence of external stakeholders. Common barriers included i) limited resources, ii) poor communication among team members, iii) incompatibility between the new intervention and existing work routine, iv) complicated implementation process, v) low practicality of supporting instruments, and vi) lack of understanding about the content and effectiveness of the new interventions. Common facilitators were i) information sharing via regular meetings on implementation issues, ii) organizational culture that values quality and accountability, iii) financial penalties for hospitals with high avoidable readmissions rates, iv) external support offered via quality improvement programs and community resources, and v) senior leadership support. Conclusions: This study synthesized commonly-presenting barriers and facilitators to implementing peri-discharge interventions among different healthcare organizations. Findings may inform development of implementation strategies in different health systems after appropriate tailoring, based on a consensus-based formative research process.

- To explore the variability in biosensor studies, 150 participants from 20 countries were given the same protein samples and asked to determine kinetic rate constants for the interaction. We chose a protein system that was amenable to analysis using different biosensor platforms as well as by users of different expertise levels. The two proteins (a 50-kDa Fab and a 60-kDa glutathione S-transferase [GST] antigen) form a relatively high-affinity complex, so participants needed to optimize several experimental parameters, including ligand immobilization and regeneration conditions as well as analyte concentrations and injection/dissociation times. Although most participants collected binding responses that could be fit to yield kinetic parameters, the quality of a few data sets could have been improved by optimizing the assay design. Once these outliers were removed, the average reported affinity across the remaining panel of participants was 620 pM with a standard deviation of 980 pM. These results demonstrate that when this biosensor assay was designed and executed appropriately, the reported rate constants were consistent, and independent of which protein was immobilized and which biosensor was used.

- Background In response to the World Health Organizations recommendation, policy makers have been adopting evidence-based healthcare approach to promote the development of traditional, complementary and integrative medicine (TCIM) into Hong Kongs health system. Disseminating synopses of clinical evidence from systematic reviews or randomized trials is regarded as a potentially effective strategy to promote evidence uptake. The study aimed to identify barriers and facilitators to implementing this strategy among Hong Kong Chinese medicine practitioners (CMPs). Methods Twenty-five CMPs aged under 45 years and trained in Hong Kong after reunification with China in 1997 were interviewed individually. Four clinical evidence synopses of randomized trials and systematic reviews on Chinese medicine interventions were presented, and CMPs were asked to comment on their applicability in routine practice. The Consolidated Framework for Implementation Research (CFIR) was applied to guide interview and analysis. Results The barriers included: i) CMPs perceived difficulties in applying complex evidence in decision-making and ii) inadequate training and limited consultation time. The facilitators were i) availability of publicly accessible and user-friendly synopses, ii) formation of community of evidence-based practice among CMPs with input from key opinion leaders, iii) opportunity for interprofessional collaborations with conventional healthcare providers, and iv) patients demand for evidence-based clinical advice. Besides, i) CMPs knowledge and beliefs in evidence-based healthcare approach, ii) presentations of evidence-based information in the synopses, and iii) clinical decision making as influenced by quality of evidence reported acted as both barriers and facilitators. Conclusions This CFIR-based qualitative study investigated how the World Health Organization recommendation of promoting evidence use in routine practice was perceived by CMPs trained in Hong Kong after reunification with China in 1997. Key barriers and facilitators to applying evidence were identified. Such results will inform tailoring of implementation strategies for promoting evidence uptake, in the context of a well-developed health system dominated by conventional medicine.
