INTRODUCTION: The COVID-19 pandemic has transformed healthcare systems worldwide. Primary care providers have been at the forefront of the pandemic response and have needed to rapidly adjust processes and routines around service delivery. The pandemic provides a unique opportunity to understand how general practices prepare for and respond to public health emergencies. We will follow a range of general practices to characterise the changes to, and factors influencing, modifications to clinical and organisational routines within Australian general practices amidst the COVID-19 pandemic. METHODS AND ANALYSIS: This is a prospective case study of multiple general practices using a participatory approach for design, data collection and analysis. The study is informed by the sociological concept of routines and will be set in six general practices in Melbourne, Australia during the 2020-2021 COVID-19 pandemic. General practitioners associated with the Monash University Department of General Practice will act as investigators who will shape the project and contribute to the data collection and analysis. The data will include investigator diaries, an observation template and interviews with practice staff and investigators. Data will first be analysed by two external researchers using a constant comparative approach and then later refined at regular investigator meetings. Cross-case analysis will explain the implementation, uptake and sustainability of routine changes that followed the commencement of the pandemic. ETHICS AND DISSEMINATION: Ethics approval was granted by Monash University (23950) Human Research Ethics Committees. Practice reports will be made available to all participating practices both during the data analysis process and at the end of the study. Further dissemination will occur via publications and presentations to practice staff and medical practitioners.

OBJECTIVE: To compare the concordance and acceptability of saliva testing with standard-of-care oropharyngeal and bilateral deep nasal swab testing for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in children and in general practice. DESIGN: Prospective multicentre diagnostic validation study. SETTING: Royal Children's Hospital, and two general practices (cohealth, West Melbourne; Cirqit Health, Altona North) in Melbourne, July-October 2020. PARTICIPANTS: 1050 people who provided paired saliva and oropharyngeal-nasal swabs for SARS-CoV-2 testing. MAIN OUTCOME MEASURES: Numbers of cases in which SARS-CoV-2 was detected in either specimen type by real-time polymerase chain reaction; concordance of results for paired specimens; positive percent agreement (PPA) for virus detection, by specimen type. RESULTS: SARS-CoV-2 was detected in 54 of 1050 people with assessable specimens (5%), including 19 cases (35%) in which both specimens were positive. The overall PPA was 72% (95% CI, 58-84%) for saliva and 63% (95% CI, 49-76%) for oropharyngeal-nasal swabs. For the 35 positive specimens from people aged 10 years or more, PPA was 86% (95% CI, 70-95%) for saliva and 63% (95% CI, 45-79%) for oropharyngeal-nasal swabs. Adding saliva testing to standard-of-care oropharyngeal-nasal swab testing increased overall case detection by 59% (95% CI, 29-95%). Providing saliva was preferred to an oropharyngeal-nasal swab by most participants (75%), including 141 of 153 children under 10 years of age (92%). CONCLUSION: In children over 10 years of age and adults, saliva testing alone may be suitable for SARS-CoV-2 detection, while for children under 10, saliva testing may be suitable as an adjunct to oropharyngeal-nasal swab testing for increasing case detection.
