Low agreement among patients and clinicians about urgency and safety to wait for assessment in primary care after hours medical care: results of cross-sectional matched surveys.

BACKGROUND: Discordance between patient and clinician perceived urgency may drive "inappropriate" presentations to after-hours medical services. This paper investigates the level of agreement between patient and clinicians' perceptions of urgency and safety to wait for an assessment at after-hours primary care services in the ACT. METHODS: Cross-sectional survey voluntarily completed by patients and then clinicians at after-hours medical services in May/June, 2019. Agreement between patients and clinicians is measured by Fleiss kappa. Agreement is presented overall, within specific categories of urgency and safety to wait, and by after-hours service type. RESULTS: 888 matched records were available from the dataset. Overall inter-observer agreement between patients and clinicians on the urgency of presentations was slight (Fleiss kappa = 0.166; 95% CI 0.117-0.215, p < 0.001). Agreement within specific ratings of urgency ranged from very poor to fair. Overall inter-rater agreement on how long it would be safe to wait for assessment was fair (Fleiss kappa = 0.209; 95% CI 0.165-0.253, p < 0.001). Agreement within specific ratings ranged from poor to fair. By site type, agreement between patients and clinicians on urgency ranged from not significant to fair and agreement for safety to wait ranged from very poor to slight. Agreement on urgency of issue was more often reported among patients attending their usual health service or seeing their usual clinician compared to patients attending an unfamiliar health service or clinician (χ2(1) = 7.283, p = 0.007 and χ2(1) = 16.268, p < 0.001, respectively). CONCLUSIONS: Low levels of agreement between patients and clinicians on perceived urgency and safety to wait for issues to be assessed indicate potential inefficiency in primary care use after-hours. Agreement on urgency of issues was more common among patients attending a familiar health service or familiar clinician. Improving health literacy, particularly health system literacy, and supporting continuity of care may help to support patients to engage with the most appropriate level of care at the most appropriate time.

Postural support requirements preferentially modulate late components of the gastrocnemius response to transcranial magnetic stimulation.

Mounting evidence suggests that motor evoked potentials (MEPs) recorded in upper limb muscles with postural support roles following transcranial magnetic stimulation receive contributions from both corticospinal and non-corticospinal descending pathways. We tested the hypothesis that neural structures responsible for regulating upright balance are involved in transmitting late portions of TMS-induced MEPs in a lower limb muscle. MEPs were recorded in the medial gastrocnemius muscles of each leg, while participants supported their upright posture in five postural conditions that required different levels of support from the target muscles. We observed that early and late portions of the MEP were modulated independently, with early MEP amplitude being reduced when high levels of postural support were required from a target muscle. Independent modulation of early and late MEPs by altered postural demand suggests largely separable transmission of each part of the MEP. The early component of the MEP is likely generated by fast-conducting corticospinal pathways, whereas the later component may be primarily transmitted along a polysynaptic cortico-reticulospinal pathway.
