Interventions to enable and reach patients with heart failure and their caregivers, with palliative care (TIER-HF-PC): a study protocol of a two-armed parallel group, open label randomised controlled trial that evaluates the effectiveness of a tiered model of palliative care in tertiary cardiac institutes in Singapore

Introduction
Palliative care (PC) improves quality of life (QOL). However, PC is currently delivered ‘too little, too late’ in heart failure (HF). Timely interventions to enable and reach patients with HF and their caregivers, with PC (TIER-HF-PC) is a novel, nurse coach-led model of PC that integrates PC into HF care. We will compare the effectiveness of TIER-HF-PC against usual care for improving patient and caregiver health outcomes. We will also evaluate implementation outcomes (such as care experience) of TIER-HF-PC.

Methods and analysis
In TIER-HF-PC, patients undergo regular distress screening. The intensity of PC treatments will be tiered based on the severity of problems detected. Minimally, all patients will receive PC education resources. Patients with moderate-intensity needs will receive PC health coaching. Patients with high-intensity needs will receive a PC physician consultation, on top of PC health coaching. Patients in usual care are not screened but can be referred to a PC physician based on cardiologist discretion.
We will recruit 240 English- or Mandarin-speaking patients with HF and up to 240 caregivers from 3 sites across 2 cardiac centres. Patients will be randomised in a 1:1 ratio to TIER-HF-PC or usual care. We will use an intention-to-treat approach for data analysis. Our primary outcome is patient QOL on the Kansas City Cardiomyopathy Questionnaire at 24 weeks. Secondary outcomes include patient healthcare utilisation, caregiver QOL and cost-effectiveness. All participants who received PC treatments will receive a service evaluation survey. Additionally, a sample of these participants and their treating healthcare staff will be purposively recruited for in-depth semistructured interviews on their TIER-HF-PC experience. Interviews will be thematically analysed. We will evaluate protocol fidelity through case notes and study process audits.

Ethics and dissemination
This study was approved by the SingHealth Institutional Ethics Review Board—review number: 2024–2213. Results of the study will be disseminated when data analysis is complete.

Trial registration number
NCT06244953.

Understanding knowledge and media influence on people with hepatitis B in Senegal: a mixed-methods study

Objectives
Public awareness and the dissemination of tailored information to lay populations are essential for highly endemic countries like Senegal to achieve hepatitis B elimination targets by 2030. In Senegal, despite its high prevalence, hepatitis B has not received sufficient attention in health communication campaigns compared with other health issues like HIV. We aimed to explore knowledge and perceptions surrounding hepatitis B virus (HBV), as well as the influence of digital media on the information accessed by individuals living with HBV in Senegal.

Design
We employed a mixed-methods approach combining qualitative semistructured interviews conducted with people living with HBV enrolled in the Senegalese hepatitis B cohort (SEN-B), with a quantitative content analysis of online news coverage focused on HBV within the online media of Senegal.

Setting
A referral University hospital in Dakar, Senegal.

Participants
29 individuals aged >18 years presenting with a positive hepatitis B surface antigen (HBsAg) with a median age of 40 years (IQR 27–54), of whom 51.7% were female.

Outcomes and analysis
Qualitative interviews were conducted between December 2019 and October 2021, and we employed purposive sampling to select participants enrolled in SEN-B. Thematic analysis facilitated a systematic synthesis of respondents’ narratives. All data analyses were performed using Atlas.ti (V.22). For content analysis of online media news collected from September 2019 to May 2022, a structured data extraction form was developed to collect relevant information from the selected online news articles. Data on readers’ comments spaces were extracted using an inductive approach and were processed using thematic analyses. The quantitative data issued from content analysis were exported to Stata SE V.17.0 (StataCorp) for statistical analysis.

Results
We observed a generalised lack of knowledge about HBV among participants, some of whom had never heard of the virus prior to their screening. Incomprehension regarding the disease contributed to feelings of fear and anxiety, leading participants to express various concerns about their personal health status, transmission, cure and treatment(s). The presence of rumours surrounding the disease further underscored the limited awareness of HBV revealing the marginal recognition of HBV as a significant societal concern. In many cases, the absence of effective health communication strategies at the national level resulted in individuals turning to traditional and online media for information, which often intensified their fears and concerns about HBV. An analysis of Senegalese media coverage about HBV included 157 articles published between 2009 and 2022. 55.4% (87/157) of these publications appeared in July, coinciding with World Hepatitis Day, while 65.0% (102/157) focused on general HBV epidemiology and activities led by the National Hepatitis Programme. Online media also served as informal spaces where unaccredited actors within the health sector promoted treatments lacking official verification. Additionally, the reactions’ spaces provided a venue for the exchange of information, though without any guarantee of its accuracy.

Conclusions
Facilitating collaboration and engagement between health communication stakeholders and communities is crucial for effectively disseminating structured information and culturally appropriate messages, ultimately contributing to raising awareness of HBV.

Hospital-based specialist palliative care involvement before and during the COVID-19 pandemic: secondary analysis of a regional retrospective decedent cohort study in Ottawa, Canada

Objectives
To determine the occurrence and clinicodemographic associations of hospital-based specialist palliative care (SPC) referral before and during the COVID-19 pandemic, timing of completed SPC consultation and comparative prevalence of ‘no cardiopulmonary resuscitation (CPR)’ orders, and end-of-life medication use, according to SPC involvement.

Design
Cross-sectional secondary analysis of a retrospective cohort study with a pre-pandemic (November 2019 to February 2020) group (Pre-COVID, n=170) and two intra-pandemic (March to August 2020) groups, one without (COVID–ve, n=170) and one with COVID-19 infection (COVID+ve, n=85). In the cohort study, Pre-COVID and COVID–ve group decedents were matched 2:1 on age, sex and care service (internal medicine/intensive care unit (ICU)) at death with COVID+ve decedents. In our current secondary analysis, clinicodemographic variables associated with SPC referral were examined in multivariable logistic regression, reporting adjusted ORs (aORs) and 95% CIs.

Setting
One quaternary and two tertiary acute care hospitals.

Participants
Decedent cohort with a terminal hospital admission (N=425).

Main outcome measures
SPC referral (yes/no) and timing of completed SPC consultation before death. Additional outcomes included ‘no CPR’ status and end-of-life medication prescription and dosing.

Results
SPC referral occurred in 70 (41.2%), 71 (41.8%) and 26 (30.6%) of the Pre-COVID, COVID–ve and COVID+ve groups, respectively (p=0.18). The aORs for SPC referral were lower for deaths in ICU (0.07; 95% CI 0.03 to 0.16) and admissions from nursing homes/long-term care (0.45; 95% CI 0.23 to 0.9), and higher for active cancer (2.5; 95% CI 1.39 to 4.39). Recipients of SPC consultation, compared with non-recipients, more frequently had a ‘no CPR’ order, had it placed earlier and were more frequently prescribed palliative end-of-life medications.

Conclusions
Hospital SPC consultation rates early in the COVID-19 pandemic were largely maintained at pre-pandemic levels. Having active cancer was positively associated with SPC referral, whereas both ICU death and having a nursing home/long-term care pre-admission source were negatively associated with referral.
