Introduction Coronavirus disease 2019 is an acute respiratory illness caused by severe acute respiratory syndrome coronavirus 2. The coronavirus disease 2019 pandemic upended the traditional paradigm of face-to-face provision of healthcare in the Australian context; as such, a telehealth model of active case management was implemented in our public health system, even though there was little supporting data for the safety of delivering patient care remotely to home-isolation patients in the setting of a highly infectious and potentially fatal illness. Methods A retrospective, single-centre, observational cohort study was performed over 6 weeks commencing 12 March 2020, including patients with coronavirus disease 2019 undergoing home isolation and being actively monitored by a coronavirus disease 2019 telephone assessment clinic. Outcomes assessed comprised: duration of active case follow-up, average number of telephone calls per patient, average number of hours managing each patient, treatment required including presentation to the emergency department or admission to hospital, patient characteristics and utilisation of other health services. Results Of 5223 severe acute respiratory syndrome coronavirus 2 tests performed, 170 individuals (3.25%) tested positive. A total of 158 were included: 76 (47.5%) male and median age 31 years (range 18–94). Median symptom duration was 13 days (interquartile range 6, range 2–34). Median length of coronavirus disease 2019 telephone assessment clinic admission was 10 days (interquartile range 7, range 3–32). A total of 1151 telephone patient encounters were undertaken, with a median of six phone calls made to each patient (interquartile range 5, range 1–20). Ten patients required repeat clinic review; all but one returned home. Six presented to emergency department, with three of these being admitted. In total, there were six admissions: one from the clinic, three from the emergency department and two direct from home (bypassing emergency department). Only four of the six admissions (or 2.5% of all patients) required low-flow oxygen therapy; none required high-flow oxygen or assisted ventilation. The remaining 140 patients (88.6%) were safely managed at home without complications. Discussion A telehealth model of care is safe, efficient and cost-effective for the management of mild-to-moderate coronavirus disease-19 and facilitates home isolation, especially of a low-risk population, thus providing reassurance that this model is sound and suitable for ongoing use.

Hyperammonaemia syndrome secondary toUreaplasmaspp. infection is well documented in the post-lung transplant population. We report a case of a man in his fifties with hyperammonaemia syndrome secondary to disseminatedUreaplasma parvuminfection. This occurred in the context of immunosuppression for chronic graft versus host disease and six years following an allogeneic stem cell transplant for diffuse large B-cell lymphoma. Following treatment ofU. parvumseptic arthritis with ciprofloxacin and doxycycline, the patient experienced a full neurological recovery, and continues on suppressive doxycycline therapy with no recurrence of symptoms to date.
