Prevalence, clinical features, and outcomes of COVID-19 in persons with cystic fibrosis: a systematic review protocol

Abstract

Objective: The objective of this review is to determine the incidence and prevalence, clinical features, and outcomes of COVID-19 in persons with cystic fibrosis. Introduction: Cystic fibrosis, predominantly a chronic respiratory illness, has long been known to be fatal with concomitant bacterial or viral infections. However, the effects of COVID-19 on this protracted disease need to be understood, especially since the major manifestations affect the respiratory system. Hence, the burden, clinical features, and outcomes of COVID-19 on individuals with cystic fibrosis need to be understood. Inclusion criteria: This review will consider studies on persons in all age groups with preexisting cystic fibrosis who are diagnosed with COVID-19 using either a polymerase chain reaction, serology, or point-of-care test for SARS-CoV-2. Methods: JBI methodology for systematic reviews of prevalence and incidence will be used for this review. A methodical search for eligible studies in English (as well as available translations) in MEDLINE, Embase, Scopus, and CINAHL, and unpublished literature in Google Scholar, Dissertation Abstracts International, ProQuest Dissertations and Theses, and MedNar will be conducted from the year 2020 onwards. Studies meeting the inclusion criteria will be selected for appraisal and their methodological quality will be assessed by two independent reviewers based on study titles and abstracts, followed by full-text review focusing on sampling and statistical analysis. Data extraction will be accomplished using a standardized tool. If adequate synthesized data are obtained, a meta-analysis will be conducted; otherwise, the findings will be presented in a narrative format, including tables and figures to aid in data presentation where appropriate.
