The impact of COVID‐19 telehealth on test completion rates is unknown. AIMS: To examine the impact of the COVID‐19 pandemic and telehealth transition on pathology and imaging test request and completion rates in Australian outpatient clinics. METHODS: We performed a prospective cohort study with historical controls between March–May 2019 and March–May 2020. Pathology and imaging request and completion rates were collected in review consultation patients attending Gastroenterology and Rheumatology outpatient clinics at a tertiary healthcare system prior and during the early phases of the COVID‐19 pandemic in Melbourne. RESULTS: 1376 patients were included in the study. Pathology tests were requested more frequently in the COVID‐19 group (n = 582/684, 85.2%) than control group (n = 492/692, 71.1%, p < 0.001) but completion rates were lower in the COVID‐19 group (n = 443/582, 76.1%) than control group (n = 426/492 (86.6%), p < 0.001). Imaging tests were requested more frequently in the COVID‐19 group (n = 345/682, 50.6%) than control group (n = 295/692, 42.6%, p = 0.003) with lower rates of completion in the COVID‐19 group (n = 229/345, 66.4%) then control group (n = 247/295, 83.7%, p < 0.001). CONCLUSIONS: The COVID‐19 pandemic and telehealth transition has resulted in more frequent pathology and imaging requests but fewer test completion in the outpatients setting. This study has identified new clinical risks associated with the abrupt transition to telehealth during COVID‐19 that should be explored in future studies and appropriately mitigated.

In Australia, over 32 million episodes of specialist outpatient care were delivered between 2019 -2020 with more than 175 million tests completed under the Medicare Benefit Scheme (MBS) 1, 2 . Tertiary hospitals provide an essential service in caring for the most vulnerable and complex members of our community. These patients tend to be older, socially disadvantaged, demonstrate lower health literacy, and are culturally and linguistically diverse (CALD) 3, 4 . Pathology and radiology testing are frequently requested within the tertiary outpatient care context and are essential in the diagnosis, monitoring and management of complex conditions. There is currently no data available on outpatient hospital test patterns and completion rates. Studies conducted in primary care demonstrated that pathology and radiology tests were ordered in 47.6% and 11.0% of encounters, respectively 5 . The rate of test adherence in primary care is suboptimal. Diabetic patients managed in primary care demonstrated 31% non-adherence to pathology testing 6 . Similarly, a study in the hospital outpatient setting revealed 37.6% of non-adherence to radiology follow-up testing 7 . Low testing completion rates have been attributed to patient forgetfulness, poor health literacy, and language barriers which further compounds the difficulty when delivering care for a complicated chronic disease cohort within an ambulatory hospital setting 6 . In response to the COVID-19 pandemic, hospitals have pivoted towards a predominantly telehealth model of specialist outpatient management to prevent nosocomial transmission. The immediate and downstream impact of such a significant disruption to the delivery of specialist outpatient services has yet to be delineated. In Australia, 86.8% of consultations Accepted Article were previously delivered in-person compared to 11.8% and 0.5% via telehealth and videoconference, respectively 3 . In-person consults provided an avenue for clinicians to perform physical examinations, entrust patients with paper-based prescriptions and test referrals, perform point-of-care investigations, and establish and reinforce the therapeutic relationship. The impact of virtual consultations on such aspects of care may be indirectly estimated from a study of telehealth in rural Australia, which highlighted the financial, cultural and technological barriers to successful telehealth implementation 8 . These barriers include insufficient funding to establish telehealth infrastructure, poor patient and clinician uptake, and lack of interoperability with existing legacy systems such as diagnostic referral systems 8 . The impact of the COVID-19 pandemic on patient adherence to outpatient test completion prior to their telehealth appointment is currently unknown. A small survey in primary care reported 32% appointment non-attendance and 21% non-adherence to pathology test completion during the COVID-19 pandemic 9 . Our study investigates the impact of telehealth transition on outpatient clinic attendance and test completion in the early phases of COVID-19 pandemic. We performed a prospective cohort study with a historical control as the comparator. Data were collected between March 3, 2020 to May 8, 2020 for the prospective cohort and between March 5, 2019 to May 10, 2019 for the historical control (pre-COVID-19) at Monash Health, a 1,536 bed tertiary health network in metropolitan Melbourne, Australia. From July 7, 2020 Metropolitan Melbourne entered state-wide lockdown with restrictions eased from November 8, 2020. Patients were identified from clinic schedules and information was obtained from the hospital's scanned medical records. The five clinics included were general gastroenterology, chronic liver disease, general rheumatology, vasculitis, and rheumatoid arthritis. Clinic attendance and appointment type (new vs. review), were assessed for all patients. Patients who were new to the clinic or did not attend the clinic appointment in the observed time frame were excluded from further analysis of pathology and radiology test ordering and completion rates. Four investigators (TLL, AR, TWL, GP) extracted clinic and patient data using a standardised template. Baseline patient demographic data including age, gender, distance from home to clinic, primary language, and interpreter requirements were collected. Information regarding the number of outpatient clinic appointments and failure to attend (FTA) rates for the 12 months prior to selected clinic appointment was obtained. Attendance at this clinic, either in-person or via telephone, was assessed for all patients. For review patients who attended the clinic, requests for pathology and imaging testing for completion prior to review were determined from the previous clinic documentation. Test completion was ascertained through the outpatient clinical documentation and cross-referenced with available results. The location for test completion was collected from internal pathology and radiology databases and scanned medical records if completed at external services. This article is protected by copyright.

Patient and clinic characteristics were summarised as mean ± standard deviation (SD), proportions, or median (interquartile range). Student's t tests and Mann-Whitney U tests were used to examine continuous variables with normal and skewed distributions, respectively. Categorical variables were analysed using chi-squared or Fisher exact test. Pvalues were two-sided with a significance level of <0.05. Subgroup analysis for rheumatology and gastroenterology clinics were specified a priori. The study was approved by the Monash Health Human Research Ethics Committee (HREC) as a quality assurance initiative. Health and this did not differ during the COVID-19 pandemic (191/227 (84.1%)) compared to prior (205/248 (82.7%), p=0.75). We investigated the impact of large-scale adoption of telehealth during the COVID-19 pandemic on specialist ambulatory care clinic attendance, pathology and imaging request and completion rates. One of the major strengths of our study was the large sample size and diverse patient population, which helped us identify real world challenges to the ongoing expansion of telehealth in the post-COVID world. How will telehealth change the way we request and act on diagnostic data? How can we best scale telehealth to a diverse realworld population? Our study challenges the assumption that telehealth can improve healthcare efficiency and produce substantial cost reductions. We demonstrated a 14.1% increase in pathology and 8.0% increase in imaging orders by clinicians during the COVID-19 pandemic. This observed change may reflect increased dependency on diagnostic testing for evaluation of disease status, driven by the inability to physically examine and assess patients in person. Whilst the demand for telehealth enabling technology (software and hardware) has increased due to the widespread adoption of outpatient telehealth in outpatient care, there is a market gap for technology which can substitute or enable the physical examination, such as abdominal or joint examination 10 . The potential for increased healthcare cost and patient harm due to increased diagnostic test requests warrants further investigation and strategies to mitigate these unintended consequences once telehealth is scaled post COVID-19. Despite an increase in test ordering, there was a reduction in test completion. Pathology test completion was reduced by 10.5% and imaging tests by 17.4%. The beginning of the COVID-19 pandemic brought about panic and uncertainty with fear of infection identified as a reason for avoidance of health services during the COVID-19 pandemic, including pathology and imaging providers 11 . The Australian population was advised to avoid all nonessential services to help stem the spread of COVID-19. This combined with the loss of an immediate physical item in the form of a paper request could be contributing factors to less test completion that occurred during the beginning of the pandemic. Furthermore, a vital part of communication is nonverbal cues which is difficult over virtual platforms. Clinic appointments often convey a lot of information and the removal of a face-to-face consultation could have an impact on patients' understanding of further management. This is particularly the case for phone consultations which lack even a visual platform in which to communicate through. In addition, the availability of services may be reduced due to social distancing measures and more stringent cleaning processes, particularly in imaging centres which have reported an anticipated 50-70% decrease in imaging volume 12 . Pathology collection centres within our network were closed during the initial phase of lockdown which also impacted on the ability of patients to complete their requested test within our health network, though we did record down external pathology results as well. The hospital system in which this study was undertaken still largely utilises paper requests for ordering outpatient investigations. With telehealth, these paper requests are now mailed to patients resulting in potential delayed or lost paperwork. This challenge is further amplified during the COVID-19 pandemic as a result of disrupted logistic services 13 . Contrary to the literature, our clinic attendance rates were not affected by the COVID-19 pandemic. Fear of COVID-19 transmission in hospital settings and the need to isolate have Accepted Article been proposed as some of the reasons for delayed or nonattendance for medical services 14 . Our tertiary centre made a pivot to telehealth consultations early on in the pandemic (March 16, 2020), allowing ongoing contact with patients without the need or fear of faceto-face consultations. Despite this, attendance rates for public hospital outpatient clinics have been historically poor, with 5-16% of all clinic bookings missed [15] [16] [17] . Our FTA rate was 17% which is consistent with the literature, but we did not contact the patients to ascertain the reason. Common reported reasons for non-attendance include forgetfulness, clerical errors, and inpatient admission at another hospital 18 . Past studies have identified factors that predict non-attendance, including age 16-30 or >90 years, and low socioeconomic status 19 . Long home-to-clinic distances have also been reported as a predictor for nonattendance 20 , a factor eliminated by the introduction of telehealth, similar to a previous study in Australia 21 . A study limitation is the difference in sample of specialty clinics between the pre-COVID-19 and COVID-19 group. While this may be a confounding factor for the difference in test orders observed in this study, a subgroup analysis found no difference in test ordering patterns prior and during the COVID-19 pandemic between the clinical services. As data were only obtained from two medical specialties, it may be difficult to generalise the findings of our study to other services, especially surgical clinics. This was conducted in the early days of the COVID-19 pandemic and the consequential rapid transition to telehealth occurred nearly simultaneously, so it is difficult to attribute our findings to one or the other. It is also unclear from this study the impact of incomplete test completion on patient outcome. This article is protected by copyright. All rights reserved. We have highlighted a significant increase in pathology and imaging test orders, and decreased rates of test completion, after widespread adoption of telehealth during the COVID-19 pandemic. Future studies should investigate the underlying reasons for poor test adherence. The health and economic impacts of increased test request and test nonadherence are yet to be elucidated, and understanding this will allow strategic allocation of funding to improve health outcomes in the setting of expanded use of telehealth during, and after, the COVID-19 pandemic.
