Effectiveness of rehabilitation interventions on the secondary consequences of surviving a cardiac arrest: a systematic review and meta-analysis

AIM

The aim of this systematic review was to assess the effectiveness of rehabilitation interventions on the secondary physical, neurological and psychological consequences of cardiac arrest (CA) for adult survivors.

METHODS

A literature search of electronic databases (MEDLINE, Allied and Complementary Medicine Database, Cumulative Index to Nursing and Allied Health Literature, Excerpta Medica database, Psychological Information Database, Web of Science and Cochrane Central Register of Controlled trials) was conducted for randomised controlled trials (RCTs) and observational studies up to 18 April 2021. The primary outcome was health-related quality of life (HRQoL) and main secondary outcome was neurological function with additional secondary outcomes being survival, rehospitalisation, safety (serious and non-serious adverse events), psychological well-being, fatigue, exercise capacity and physical capacity. Two authors independently screened studies for eligibility, extracted data and assessed risk of bias.

RESULTS

Three RCTs and 11 observational studies were included (total 721 participants). Study duration ranged from 8 weeks to 2 years. Pooled data from two RCTs showed low-quality evidence for no effect on physical HRQoL (standardised mean difference (SMD) 0.19, (95% CI: -0.09 to 0.47)) and no effect on mental HRQoL (SMD 0.27 (95% CI: -0.01 to 0.55)).Regarding secondary outcomes, very low-quality evidence was found for improvement in neurological function associated with inpatient rehabilitation for CA survivors with acquired brain injury (SMD 0.71, (95% CI: 0.45 to 0.96)) from five observational studies. Two small observational studies found exercise-based rehabilitation interventions to be safe for CA survivors, reporting no serious or non-serious events.

CONCLUSIONS

Given the overall low quality of evidence, this review cannot determine the effectiveness of rehabilitation interventions for CA survivors on HRQoL, neurological function or other included outcomes, and recommend further high-quality studies be conducted. In the interim, existing clinical guidelines on rehabilitation provision after CA should be followed to meet the high burden of secondary consequences suffered by CA survivors.

Rehabilitation and palliative care for socioeconomically disadvantaged patients with advanced cancer: a scoping review

BACKGROUND

Rehabilitation and palliative care may play an important role in addressing the problems and needs perceived by socioeconomically disadvantaged patients with advanced cancer. However, no study has synthesized existing research on rehabilitation and palliative care for socioeconomically disadvantaged patients with advanced cancer. The study aimed to map existing research of rehabilitation and palliative care for patients with advanced cancer who are socioeconomically disadvantaged.

MATERIAL AND METHODS

A scoping review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). A systematic literature search was performed in CINAHL, PubMed and EMBASE. Two reviewers independently assessed abstracts and full-text articles for eligibility and performed data extraction. Both qualitative and quantitative studies published between 2010 and 2019 were included if they addressed rehabilitation or palliative care for socioeconomically disadvantaged (adults ≥18 years) patients with advanced cancer. Socioeconomic disadvantage is defined by socioeconomic position (income, educational level and occupational status).

RESULTS

In total, 11 studies were included in this scoping review (138,152 patients and 45 healthcare providers) of which 10 were quantitative studies and 1 was a qualitative study. All included studies investigated the use of and preferences for palliative care, and none focused on rehabilitation. Two studies explored health professionals' perspectives on the delivery of palliative care.

CONCLUSION

Existing research within this research field is sparse. Future research should focus more on how best to reach and support socioeconomically disadvantaged people with advanced cancer in community-based rehabilitation and palliative care.
