Rationale: Pneumococcal colonization is key to the pathogenesis of invasive disease but is also immunogenic in young adults, protecting against recolonization. Colonization is rarely detected in older adults, despite high rates of pneumococcal disease. Objectives: To establish experimental human pneumococcal colonization in healthy adults aged 50–84 years, to measure the immune response to pneumococcal challenge, and to assess the protective effect of prior colonization against autologous strain rechallenge. Methods: Sixty-four participants were inoculated with Streptococcus pneumoniae (serotype 6B; 80,000 cfu in each nostril). Colonization was determined by bacterial culture of nasal wash, and humoral immune responses were assessed by anticapsular and antiprotein IgG concentrations. Measurements and Main Results: Experimental colonization was established in 39% of participants (25/64) with no adverse events. Colonization occurred in 47% (9/19) of participants aged 50–59 compared with 21% (3/14) in those aged ≥70 years. Previous pneumococcal polysaccharide vaccination did not protect against colonization. Colonization did not confer serotype-specific immune boosting, with a geometric mean titer (95% confidence interval) of 2.7 μg/ml (1.9–3.8) before the challenge versus 3.0 (1.9–4.7) 4 weeks after colonization (P = 0.53). Furthermore, pneumococcal challenge without colonization led to a drop in specific antibody concentrations from 2.8 μg/ml (2.0–3.9) to 2.2 μg/ml (1.6–3.0) after the challenge (P = 0.006). Antiprotein antibody concentrations increased after successful colonization. Rechallenge with the same strain after a median of 8.5 months (interquartile range, 6.7–10.1) led to recolonization in 5/16 (31%). Conclusions: In older adults, experimental pneumococcal colonization is feasible and safe but demonstrates different immunological outcomes compared with younger adults in previous studies.

Objective Empathy and empathy education have been reviewed a number of times through systematic reviews and meta-analyses; however, the topic of ‘empathetic communication’ remains poorly understood when considering engaging in hospital-based research. Therefore, this scoping review aimed to explore the existing literature concerning empathetic communication in hospital settings and to evaluate the definitions presented. Design Scoping review. Data sources Systematic searches of the PubMed, CINAHL, Cochrane, PsycINFO, and PsycArticles databases were conducted. Study selection All English studies in which empathetic communication in hospital settings were explored. The search terms used included empathy, communication, hospital settings, providers, and consumers. Data extraction Data were assessed through the use of a pre-set analysis tool. Results After conducting the searches, 419 articles were identified, of which 26 were included in this review. No single article specifically defined the term ‘empathetic communication’; however, 33 unique definitions of ‘empathy’ were identified, of which 23 considered communication to be a component of empathy. There was a considerable lack of consistency between the empathy definitions, with some classifying communication in empathy as an ability and others classifying it as a dynamic process. Conclusion Future and contextually focused research is needed to develop a consistent and clear definition of empathetic communication and empathy within a hospital setting to better build positive healthcare cultures. Practice implications Inconsistencies between definitions of empathy in empathetic communication research could reduce the efficacy of future research gains and impact the translation of research findings into clinical practice.

Objective: Patient experience significantly impacts healthcare quality, outcomes, resource utilisation and treatment adherence. Digital technologies offer promising approaches for capturing real-time, multi-faceted patient experiences. This scoping review investigated how digital technologies are used to capture patient experience during healthcare encounters and their potential to improve health service delivery and care. Methods: A scoping review was conducted to determine associations between patients’ use of digital technology and subsequent outcomes. Four electronic databases were searched using six combination search terms in titles and/or abstracts published between 2016 and 2022. Inclusion criteria focused on studies where patients were primary users of digital technology, reporting on their experience during care. Studies had to report on at least one outcome: health service delivery, quality of care or patient experience. Screening, data extraction and analysis were performed systematically. Results: Of the 377 studies retrieved, 20 were included. Most studies incorporated aspects allowing patients to share experiences with digital technologies. Eighty percent ( n = 16) of studies reported improvements in patient experiences, 75% ( n = 15) enhancements in service delivery aspects and 50% ( n = 10) indicated improved quality of care associated with the use of digital technologies. Real-time journaling and narrative methods alongside treatment were linked to improved communication, healthcare efficiencies and patient agency. Technologies facilitating bidirectional communication were particularly associated with positive effects on patients’ sense of agency. Conclusion: Digital technologies facilitating documentation of patient experiences demonstrate potential in enhancing care quality through increased patient voice, collaboration and agency. Technologies designed to map and evaluate patients’ healthcare experiences represent a promising approach to improving healthcare outcomes, service delivery and overall patient experience. Further research is needed to establish standardised methodologies and evaluate long-term impacts across diverse populations. Integrating digital narrative medicine principles may offer valuable insights for future interventions aimed at capturing and enhancing patient experiences in healthcare.

Critically ill morbidly obese patients pose considerable healthcare delivery and resource utilisation challenges. However little is known about the care of these patients in intensive care. To explore medical and nursing practices and attitudes in intensive care when caring for critically ill morbidly obese patients. A focused ethnographic approach was adopted. Participant observation of care practices and interviews with intensive care doctors and nurses were undertaken over a four month period. Qualitative analysis was conducted using constant comparison. An 18 bedded tertiary intensive care unit in New Zealand. Sixty-seven intensive care nurses and 13 intensive care doctors involved with the care and management of seven critically ill patients with a body mass index ≥40kg/m2. Morbidly obese patients present significant physical and language challenges for intensive care practice. The physical shape of morbidly obese patients did not appropriately fit the different equipment used. Staff used specific knowledge of the patient's body size and shape to adapt care practices and keep patients safe and comfortable. There were also specific language challenges where staff expressed concern about what words were most appropriate to use to describe body mass when in the presence of morbidly obese patients. Bariatric care pathways need to be developed that use more suitable body measurements to inform the use of bariatric equipment. Intensive care staff need to engage in debate about what is acceptable, respectful, and appropriate language in the delivery of bariatric patient care.

Critically ill morbidly obese patients pose considerable healthcare delivery and resource utilisation challenges in the intensive care setting. These are resultant from specific physiological responses to critical illness in this population and the nature of the interventional therapies used in the intensive care environment. An additional challenge arises for this population when considering the social stigma that is attached to being obese. Intensive care staff therefore not only attend to the physical and care needs of the critically ill morbidly obese patient but also navigate, both personally and professionally, the social terrain of stigma when providing care. To explore the culture and influences on doctors and nurses within the intensive care setting when caring for critically ill morbidly obese patients. A focused ethnographic approach was adopted to elicit the 'situated' experiences of caring for critically ill morbidly obese patients from the perspectives of intensive care staff. Participant observation of care practices and interviews with intensive care staff were undertaken over a four month period. Analysis was conducted using constant comparison technique to compare incidents applicable to each theme. An 18 bedded tertiary intensive care unit in New Zealand. Sixty-seven intensive care nurses and 13 intensive care doctors involved with the care and management of seven critically ill patients with a body mass index ≥40kg/m(2). Interactions between intensive care staff and morbidly obese patients were challenging due to the social stigma surrounding obesity. Social awkwardness and managing socially awkward moments were evident when caring for morbidly obese patients. Intensive care staff used strategies of face-work and mutual pretence to alleviate feelings of discomfort when engaged in aspects of care and caring. This was a strategy used to prevent embarrassment and distress for both the patients and staff. This study has brought new understandings about intensive care situations where social awkwardness occurs in the context of obesity and care practices, and of the performances and behaviours of staff in managing the social awkwardness of fat-stigma during care situations.
