Supporting referral to pulmonary rehabilitation from primary care: A systematic evaluation of interventions using the ERIC taxonomy.
Synthesis in NPJ primary care respiratory medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPulmonary rehabilitation (PR) is a key component in managing chronic respiratory diseases (CRDs). Primary care, often the first point of contact for people with CRD, is well-positioned to facilitate referral to PR, yet referral rates are low. This systematic review aimed to identify the key components of primary care interventions to support referral to PR and synthesise their effect on referral rate.
methodsFive electronic databases were searched to identify studies of any design that reported interventions implemented in primary care to support referral to PR for people with CRD. Interventions could target people with CRD and/or healthcare professionals. Screening, quality appraisal using the Downs and Black checklist, and data extraction were conducted independently by two reviewers. Interventions were mapped to the Expert Recommendations for Implementing Change (ERIC) taxonomy-a framework of 73 strategies seeking to enhance the adoption, implementation, and sustainability of evidence-based interventions.
resultsThirteen studies were included, employing a range of quasi-experimental, observational, and randomised designs. Overall, the studies were of moderate quality (mean total score 14, range 10 to 25 out of 27). Interventions incorporated a mean of 12 ERIC strategies across five domains, most commonly education and training, interactive assistance, clinician support, and audit and feedback. Impact of interventions on referral rates was minimal (n = 3 randomised controlled trials, pooled mean difference 0%, 95% confidence interval -0.24 to 0.25).
interpretationMulti-component interventions, including numerous implementation strategies, have achieved minimal improvement in PR referral rates from primary care. Understanding how strategies are delivered and applied, rather than simply the number of strategies or the combination they are used in, may be important for operationalisation of referral focussed interventions. Addressing the behavioural processes underpinning referral decisions, together with the use of theory-informed, context-specific approaches may enhance effectiveness of referral focussed interventions.
