Admission to and Continuation of Inpatient Stroke Rehabilitation in Queensland, Australia: A Survey of Factors that Contribute to the Consultant's Decision

Social Isolation and Social Support Influence Health Service Utilisation and Survival after a Cardiovascular Disease Event: A Systematic Review

Both cardiovascular disease (CVD) and social health carry high health and economic burdens. We undertook a systematic review to investigate the association between social isolation, low social support, and loneliness with health service utilisation and survival after a CVD event among people living in Australia and New Zealand. Four electronic databases were systematically searched for the period before June 2020. Two reviewers undertook the title/abstract screen. One reviewer undertook a full-text screen and data extraction. A second author checked data extraction. Of 756 records, 25 papers met our inclusion criteria. Included studies recruited 10-12,821 participants, aged 18-98 years, and the majority were males. Greater social support was consistently associated with better outcomes on four of the five themes (discharge destination, outpatient rehabilitation attendance, rehospitalisation and survival outcomes; no papers assessed the length of inpatient stay). Positive social health was consistently associated with better discharge designation to higher independent living. As partner status and living status did not align with social isolation and social support findings in this review, we recommend they not be used as social health proxies. Our systematic review demonstrates that social health is considered in cardiac care decisions and plays a role in how healthcare is being delivered (i.e., outpatient, rehabilitation, or nursing home). This likely contributes to our finding that lower social support is associated with high-intensity healthcare services, lower outpatient rehabilitation attendance, greater rehospitalisation and poorer survival. Given our evidence, the first step to improve cardiac outcomes is acknowledging that social health is part of the decision-making process. Incorporating a formal assessment of social support into healthcare management plans will likely improve cardiac outcomes and survival. Further research is required to assess if support person/s need to engage in the risk reduction behaviours themselves for outpatient rehabilitation to be effective. Further synthesis of the impact of social isolation and loneliness on health service utilisation and survival after a CVD event is required.

Factors influencing clinicians' referral or admission decisions for post-acute stroke or traumatic brain injury rehabilitation: A scoping review

Demand for post-acute stroke and traumatic brain injury (TBI) rehabilitation outweighs resource availability. Every day, clinicians face the challenging task of deciding which patient will benefit or not from rehabilitation. The objectives of this scoping review were to map and compare factors reported by clinicians as influencing referral or admission decisions to post-acute rehabilitation for stroke and TBI patients, to identify most frequently reported factors and those perceived as most influential. We searched four major databases for articles published between 1946 and January 2021. Articles were included if they reported clinicians' perceptions, investigated referral or admission decisions to post-acute rehabilitation, and focused on patients with stroke or TBI. Twenty articles met inclusion criteria. The International Classification of Functioning, Disability and Health framework was used to guide data extraction and summarizing. Patient-related factors most frequently reported by clinicians were age, mental status prior to stroke or TBI, and family support. The two latter were ranked among the most influential by clinicians working with stroke patients, whereas age was ranked of low importance. Organizational factors were reported to influence decisions (particularly the availability of post-acute care services) as well as clinicians' characteristics (eg, knowledge). Moreover, clinicians' prediction of patient outcome ranked among the most important driver of referral or admission decisions by clinicians working with stroke patients. Findings highlight the complex nature of decision-making regarding patient selection for rehabilitation and provide insight on important factors that frontline clinicians need to consider when having to make rapid decisions in high-pressured acute care environments.

Repetitive reaching training combined with transcranial Random Noise Stimulation in stroke survivors with chronic and severe arm paresis is feasible: a pilot, triple-blind, randomised case series

Background

Therapy that combines repetitive training with non-invasive brain stimulation is a potential avenue to enhance upper limb recovery after stroke. This study aimed to investigate the feasibility of transcranial Random Noise Stimulation (tRNS), timed to coincide with the generation of voluntary motor commands, during reaching training.

Methods

A triple-blind pilot RCT was completed. Four stroke survivors with chronic (6-months to 5-years) and severe arm paresis, not taking any medications that had the potential to alter cortical excitability, and no contraindications to tRNS or MRI were recruited. Participants were randomly allocated to 12 sessions of reaching training over 4-weeks with active or sham tRNS delivered over the lesioned hemisphere motor representation. tRNS was triggered to coincide with a voluntary movement attempt, ceasing after 5-s. At this point, peripheral nerve stimulation enabled full range reaching. To determine feasibility, we considered adverse events, training outcomes, clinical outcomes, corticospinal tract (CST) structural integrity, and reflections on training through in-depth interviews from each individual case.

Results

Two participants received active and two sham tRNS. There were no adverse events. All training sessions were completed, repetitive practice performed and clinically relevant improvements across motor outcomes demonstrated. The amount of improvement varied across individuals and appeared to be independent of group allocation and CST integrity.

Conclusion

Reaching training that includes tRNS timed to coincide with generation of voluntary motor commands is feasible. Clinical improvements were possible even in the most severely affected individuals as evidenced by CST integrity.
