Objectives: Telephone-based consults using remote imaging review and standardization of evaluation but without visualizing the patient are an alternative to video-telestroke consults but are less well-studied. We aim to demonstrate the safety and efficacy of telephone-based acute consults in which IV tPA was administered over nearly a decade within one health system.
Materials And Methods: Clinical characteristics and outcomes were compared between a community hospital (spoke; uses telephone-based consults) and the academic comprehensive stroke center (hub; uses oversight of on-site neurology trainees) from 2008-2017. In both institutions acute therapy decisions are made by the same stroke neurologists.
Results: 2518 acute ischemic stroke consults were evaluated at hub and 2049 at spoke. Of these, 191 patients received IV tPA at hub and 184 at spoke. Patients at hub were younger (median (IQR): 61 (51-74) vs 69 (56-81) years, p = 0.0021) but admission National Institutes of Health Stroke Scale (NIHSS) was similar. There were no differences between door-to-needle times (69 (56-101) vs 69 (51-92) minutes, p = 0.13), last known well-to-tPA times (157 (113-202) vs 144 (110-175) minutes, p = 0.053), and rates of overall intracranial hemorrhage (ICH) after tPA (n = 23 (13.5%) vs 31 (17.0%), p = 0.35). In multivariable analyses, hospital was not an independent predictor of ICH after tPA.
Conclusions: In a large dataset over nearly a decade, assessment for IV tPA administration using telephone assessment along with imaging review and emergency department standardization resulted in similar safety and outcomes as in the presence of on-site stroke/neurology expertise. Future studies are needed to confirm these findings.

Clinical Outcomes and Resource Efficiency of a Telehealth Model for New Lower Gastrointestinal Bleeding Referrals: A Tertiary Colorectal Outpatient Service Audit.
Int J Telemed Appl

Amidst the COVID-19 pandemic, telehealth (TH) has gained increasing relevance in colorectal patient care, prompting an audit of the TH clinic at a tertiary colorectal unit. This study evaluated telephone-based consultations' clinical efficacy and diagnostic thresholds for new lower gastrointestinal (LGI) bleeding referrals. We conducted a quality assurance audit of the per rectal (PR) bleeding TH clinic at Northern Hospital Victoria, evaluating new LGI bleeding referrals.

Background: Telehealth services are becoming increasingly popular at primary healthcare centres. Some examples include text-based digital triage and health guidance using chats, emails, images and pre-filled forms. Telephone-based communication has until recent years been the predominant means for triage and health guidance, but now includes written communication via computer or smartphone.

Importance: An unhealthy lifestyle is believed to increase the development and persistence of low back pain, but there is uncertainty about whether integrating support for lifestyle risks in low back pain management improves patients' outcomes.
Objective: To assess the effectiveness of the Healthy Lifestyle Program (HeLP) compared with guideline-based care for low back pain disability.
Design, Setting, And Participants: This superiority, assessor-blinded randomized clinical trial was conducted in Australia from September 8, 2017, to December 30, 2020, among 346 participants who had activity-limiting chronic low back pain and at least 1 lifestyle risk (overweight, poor diet, physical inactivity, and/or smoking), referred from hospital, general practice, and community settings.
The role of optometry in healthcare for visually impaired older adult populations: a Swiss case study.

Background: Visual impairment (VI) is common among older adults aged 70 years and older, and its prevalence increases with advancing age. The optometry profession may play an important role in a patient-centred health system that incorporates medical and psychosocial aspects by working closely with low vision counselling services (LVCS). This paper investigates the current level of cooperation between optometry and LVCS by analysing the referral practice of optometrists to LVCS for the older population with VI, based on the PROVIAGE study.
