NCT04390165

Brief Summary

The Malaysian COVID-19 Anosmia Study is a nationwide multicentre observational study to investigate the prevalence and characteristics of olfactory and gustatory/taste disturbances in COVID-19 infection in Malaysia, and to evaluate the predictive value of screening for these symptoms in COVID-19 infection. This study consists of two phases: the first phase is a cross-sectional study and the second phase is a case-control study. The cross-sectional study is described here (the case-control study is described in a separate ClinicalTrials.gov record).

Outcome Measures

Primary Outcomes (3)

  • Presence or absence of olfactory and taste disturbances in COVID-19 patients

    In the patient-reported online questionnaire, subjects will be asked regarding whether they experienced symptoms of olfactory and/or taste disturbances

    Within 2 weeks preceding the diagnosis of COVID-19 infection

  • Prevalence of olfactory disturbances in COVID-19 patients

    Percentage of COVID-19 patients experiencing olfactory disturbances (anosmia or hyposmia)

    Within 2 weeks preceding the diagnosis of COVID-19 infection

  • Prevalence of taste disturbances in COVID-19 patients

    Percentage of COVID-19 patients experiencing taste disturbances

    Within 2 weeks preceding the diagnosis of COVID-19 infection

Secondary Outcomes (5)

  • Clinical manifestations of study participants

    Within 2 weeks preceding the diagnosis of COVID-19 infection

  • Other pre-existing health conditions

    Prior to diagnosis of COVID-19 infection

  • Rating of baseline sense of smell & taste in COVID-19 patients prior to diagnosis of their infection

    Prior to 2 weeks preceding the diagnosis of COVID-19 infection (Baseline)

  • Rating of sense of smell & taste in COVID-19 patients at time of diagnosis of their infection

    Within 2 weeks preceding the diagnosis of COVID-19 infection

  • Rating of sense of smell & taste in COVID-19 patients at time of answering questionnaire survey

    Up to 6 months

Study Arms (1)

Malaysian COVID-19 Cohort

A cohort of COVID-19 positive patients will be recruited from participating Malaysian Ministry of Health-designated COVID-19 treating hospitals across the country.

Other: Patient-Reported Online Questionnaire on Olfactory & Taste Disturbances

Interventions

This is an online patient-reported questionnaire that examines the presence or absence of olfactory and taste disturbances, the onset of olfactory and taste disturbances in relation to other COVID-19 symptoms, and the temporal evolution of the severity of olfactory and taste disturbances. The occurrence of ear symptoms in COVID-19 infection will also be evaluated in this questionnaire as a secondary outcome. The questionnaire will also have questions relating to the patient's underlying health conditions, risk factors for COVID-19 infection, and demographics.

Sampling MethodProbability Sample
Study Population

The study population are adult patients with laboratory-confirmed COVID-19 infection from participating Malaysian hospital sites in this study, since the arrival of COVID-19 infection in Malaysia (January 2020) until present time. These patients comprise those who either currently inpatient or already discharged into the community. For patients already discharged into the community, they will be invited to participate by phone call from the hospital treating team. Once verbal consent has been obtained, they a QR code or internet URL link to the online questionnaire website will be sent to these patients.

You may qualify if:

  • Age at least 18 years old
  • Laboratory confirmed COVID-19 infection \[Reverse Transcription Polymerase Chain Reaction (RT-PCR)\]
  • Patients clinically able to answer the questionnaire

You may not qualify if:

  • Patients with olfactory or taste/gustatory disorders before the COVID-19 epidemic
  • Patients without a laboratory-confirmed COVID-19 diagnosis
  • Patients in intensive care unit at the time of study
