How effective are allied health group interventions for the management of adults with long-term conditions? An umbrella review of systematic reviews and its applicability to the Australian primary health system.

BACKGROUND

Group allied health interventions for people with chronic conditions may be a solution to increasing access to allied health in primary care. This umbrella review aimed to determine the effectiveness of allied health group interventions to improve health-related outcomes for adults with chronic conditions and the applicability of the findings to the Australian primary health care context.

METHODS

An umbrella review of systematic reviews conducted April-July 2022, searching eight databases. Systematic reviews were eligible if they included randomised controlled trials (RCT) or quasi-RCTs, community dwelling adults aged ≥ 18, at least one chronic condition, group intervention in scope for allied health professionals, and published in English after 2000. Studies were excluded if interventions were conducted in hospital or aged care facilities, out of scope for allied health, or unsupervised.

RESULTS

Two thousand three hundred eighty-five systematic reviews were identified: after screening and full text review 154 were included and data extracted from 90. The chronic conditions included: cancer (n = 15), cardiovascular disease (n = 6), mixed chronic conditions (n = 3), kidney disease (n = 1), low back pain (n = 12), respiratory disease (n = 8), diabetes (n = 14), heart failure (n = 9), risk of falls (n = 5), hypertension (n = 4, osteoarthritis (n = 6) and stroke (n = 8). Most group interventions included prescribed exercise and were in scope for physiotherapists and exercise physiologists. Overall, allied health group exercise programs for community dwelling adults improved health outcomes for most chronic conditions. Aggregated data from the systematic reviews suggests programs of 45-60 min per session, 2-3 times per week for 12 weeks. Lifestyle education and support for people with type-2 diabetes improved glycaemic control.

CONCLUSIONS

Prescribed group exercise delivered by allied health professionals, predominantly by exercise physiologists and physiotherapists, significantly improved health outcomes for community dwelling adults with a broad range of chronic conditions.
