Goal setting as part of a holistic intervention to promote independence in older people with mild frailty: a process evaluation alongside a randomised controlled trial.

BACKGROUND: Frailty is a condition resulting from a decline in physiological reserves caused by an accumulation of several deficits, which progressively impairs the ability to recover from health adverse events. Following a promising feasibility study, the HomeHealth trial assessed a holistic tailored intervention for older adults with mild frailty to promote independence in their own homes, compared with usual care. We aimed to understand how goal setting worked among older people with mild frailty. METHODS: This study was a process evaluation alongside the HomeHealth randomised trial in older adults with mild frailty. The intervention was delivered at participants' homes, either in person or by telephone or videoconferencing. We carried out semi-structured interviews with older participants who had received the intervention (between three and six appointments), on average 233 days (range 68-465) after their last appointment, purposively sampled according to age, gender, number of sessions attended, adverse events, ethnicity, Index of Multiple Deprivation, Montreal Cognitive Assessment (MoCA) and Barthel scores, research site, and HomeHealth worker. We also conducted interviews with HomeHealth workers who delivered the intervention (n=7). Interviews explored the experience and process of goal setting, benefits and challenges, perceived progress, and behaviour change maintenance after the service had finished. Ethics approval was obtained, and all participants gave informed consent. Interviews were thematically analysed. HomeHealth workers kept formal records of goals set and assessed progress towards goals (0-2 rating scale) during six monthly-sessions, which were descriptively summarised. FINDINGS: 56 interviews were completed between July 15, 2022, and May 18, 2023. Study participants (n=49) had a mean age of 80 years (range 66-94), including 32 (65%) women and 17 (35%) men. Participants self-identified as White (n=42), Asian (n=3), Black (n=2), Mixed (n=1), and other ethnic (n=1) backgrounds. Findings suggested goal setting could be both a challenge and a motivator for older participants with mild frailty. Goal setting worked well when the older person could identify a clear need and set realistic goals linked to functioning, which led to a positive sense of achievement. Challenges occurred when older people were already accessing multiple resources and health services, or where the terminology of "goals" was off-putting due to work or school connotations. Average progress towards goals was 1·15/2. Most participants set goals around improving mobility (or a combination of mobility and another goal type such as socialising), and there was evidence of participants sustaining these behaviour changes after the intervention. INTERPRETATION: Older people with mild frailty can engage well with goal setting to promote independence. The lapse between receiving the intervention and being interviewed limited recall for some participants. However, the acceptability and adherence to the intervention for older people with mild frailty, and their moderate progress towards goals, should encourage further tailored and person-centred practices to promote their independence.

The effect of prone positioning on maternal haemodynamics and fetal wellbeing in the third trimester-A primary cohort study with a scoping review.

INTRODUCTION: Supine sleep position is associated with stillbirth, likely secondary to inferior vena cava compression, and a reduction in cardiac output (CO) and uteroplacental perfusion. Evidence for the effects of prone position in pregnancy is less clear. This study aimed to determine the effect maternal prone position on maternal haemodynamics and fetal heart rate, compared with left lateral position. METHODS: Twenty-one women >28 weeks' gestation underwent non-invasive CO monitoring (Cheetah) every 5 minutes and continuous fetal heart rate monitoring (MONICA) in left lateral (20 minutes), prone (30 minutes), followed by left lateral (20 minutes). Anxiety and comfort were assessed by questionnaires. Regression analyses (adjusted for time) compared variables between positions. The information derived from the primary study was used in an existing mathematical model of maternal circulation in pregnancy, to determine whether occlusion of the inferior vena cava could account for the observed effects. In addition, a scoping review was performed to identify reported clinical, haemodynamic and fetal effects of maternal prone position; studies were included if they reported clinical outcomes or effects or maternal prone position in pregnancy. Study records were grouped by publication type for ease of data synthesis and critical analysis. Meta-analysis was performed where there were sufficient studies. RESULTS: Maternal blood pressure (BP) and total vascular resistance (TVR) were increased in prone (sBP 109 vs 104 mmHg, p = 0.03; dBP 74 vs 67 mmHg, p = 0.003; TVR 1302 vs 1075 dyne.s-1cm-5, p = 0.03). CO was reduced in prone (5.7 vs 7.1 mL/minute, p = 0.003). Fetal heart rate, variability and decelerations were unaltered. However, fetal accelerations were less common in prone position (86% vs 95%, p = 0.03). Anxiety was reduced after the procedure, compared to beforehand (p = 0.002), despite a marginal decline in comfort (p = 0.04).The model predicted that if occlusion of the inferior vena cava occurred, the sBP, dBP and CO would generally decrease. However, the TVR remained relatively consistent, which implies that the MAP and CO decrease at a similar rate when occlusion occurs. The scoping review found that maternal and fetal outcomes from 47 included case reports of prone positioning during pregnancy were generally favourable. Meta-analysis of three prospective studies investigating maternal haemodynamic effects of prone position found an increase in sBP and maternal heart rate, but no effect on respiratory rate, oxygen saturation or baseline fetal heart rate (though there was significant heterogeneity between studies). CONCLUSION: Prone position was associated with a reduction in CO but an uncertain effect on fetal wellbeing. The decline in CO may be due to caval compression, as supported by the computational model. Further work is needed to optimise the safety of prone positioning in pregnancy. TRIAL REGISTRATION: This trial was registered at clinicaltrials.gov (NCT04586283).

Impact of Visual Barrier Removal on the Behavior of Shelter-Housed Dogs.

With millions of dogs housed in shelters each year, it is important to consider how the shelter environment impacts welfare. Social isolation and a lack of control over the environment can negatively impact wellbeing. However, providing social opportunities requires costly resources and can raise concerns about increased barking. In this study, 17 dogs were observed before, during, and after a visual barrier was partially removed to increase the ability to see to other dogs and the surrounding room. Stress behaviors, crate position, and resting behaviors did not differ significantly across phases; however, vocalizations were lower in the visual access and post phases (Friedman's test, p = .02). In addition, in-room barking data (N = 66) revealed no change in barking duration when barriers were removed. This absence of an increase in vocalizations should alleviate some concerns with allowing visual social contact. However, the lack of impact on stress and resting behaviors may indicate that visual social contact alone is insufficient for providing significant welfare benefits and that shelters should prioritize increasing social contact through playgroups or group housing.
