Public health palliative care interventions that enable communities to support people who are dying and their carers: a scoping review of studies that assess person-centered outcomes.

Background: Public health palliative care views communities as an integral part of care delivery at the end of life. This community-provider partnership approach has the potential to improve end-of-life care for people who are dying and their carers. Objective: To identify and appraise the current literature related to public health interventions that enable communities to support people who are dying and their carers. Methods: A scoping review was conducted, applying Arksey and O'Malley's methods. Data was extracted and synthesized using narrative techniques, and results are reported using PRISMA guidelines. Results: The search yielded 2,902 results. Eighteen met inclusion criteria and were included in the analysis. Interventions were categorized according to their target population: people with life-limiting illness (ex. facilitated social interaction, helplines and guided discussions about death and dying); carers (ex. social support mapping, psychoeducation, and community resource identification and facilitation); or dyads (ex. reminiscence activities, practical and emotional support from volunteers, online modules to bolster coping mechanisms). Public health palliative care approaches were delivered by key community stakeholders such as community health workers, volunteers, peer mentors, and pre-established support groups. Despite reported challenges in identifying appropriate tools to measure effectiveness, studies report improvement in quality of life, loneliness, social support, stress and self-efficacy. Conclusion: We found that community-engaged palliative care interventions can lead to appreciable changes in various outcomes, though it was difficult to determine in which contexts this approach works best because of the dearth of contextual information reported. Based on the varied design and implementation strategies, it is clear that no one method for enhancing end of life care will benefit all communities and it is crucial to engage community members at all stages of the design and implementation process. Future research should be grounded in appropriate theory, describe contextual differences in these communities, and should specifically examine how demographics, resource availability, and social capital might impact the design, implementation, and results of public health palliative care interventions.

Multipoint pacing improves peripheral hemodynamic response: Noninvasive assessment using radial artery tonometry.

BACKGROUND: Multipoint left ventricular (LV) pacing (MultiPoint™ Pacing [MPP], Abbott, Sylmar, CA, USA) improves the response rate to cardiac resynchronization therapy (CRT). We evaluated the feasibility of noninvasive radial artery tonometry (RAT) to characterize arterial pressure morphology changes (pre-ejection period [PEP] and ejection duration [ED]) between conventional CRT and MPP pacing interventions. METHODS: Patients with a MPP-enabled CRT device (Quadra Assura MP™, Abbott) underwent noninvasive RAT assessment (SphygmoCor CVMS, AtCor Medical Inc., Itasca, IL, USA) at 3-6 months after implantation. A pacing protocol was performed in a randomized order including one optimized conventional biventricular CRT (CONV) configuration using the distal electrode and five MPP configurations. The PEP, ED, and PEP/ED ratio were determined for each intervention from the RAT pressure waveform and electrocardiogram. RESULTS: Pressure waveforms were successfully recorded in 19 patients (89% male, QRS 147 ± 16 ms, 63% ischemic). In 17/19 (89%) patients, at least one MPP intervention resulted in improved PEP, ED, and PEP/ED compared to CONV. The MPP intervention with greatest separation of LV cathodes and minimum intra-LV delay significantly improved PEP (mean PEP -15 ± 33% vs -8 ± 32% [CONV], P = 0.04) and ED (mean ED +8 ± 8% [MPP] vs +4 ± 7% [CONV], P = 0.02), and PEP/ED (-0.07 ± 0.14 [MPP] vs -0.04 ± 0.13 [CONV], P = 0.02) compared with CONV. CONCLUSIONS: Noninvasive RAT efficiently characterizes changes in PEP and ED between CONV and MPP interventions. MPP configurations using the widest separation among LV cathodes and minimum intra-LV delay may significantly improve RAT-derived parameters as compared to conventional CRT.
