Study summary

Up to 20% of patients with Covid-19 develop symptoms that last more than 3 months, which is known as long Covid or Post-Covid-19 condition. The mechanism of the long term symptoms is not totally understood although inflammation, autoimmune reactions and thromboembolism are among suspected contributors. At Helsinki University hospital, a long Covid clinic was opened in June 2021. The aim of this cohort study is to monitor the patients that attend the clinic, follow up their functional abilities, quality of life and prognosis.

Read the detailed description

The patients are asked to give their informed consent for the participation in the cohort study. They fill in a questionnaire before entering the clinic that assesses their symptoms, previous medical history, medications, lifestyle, symptoms, sleep, psychosocial measures including depression, anxiety, resilience and quality of life.

The patients are asked to give blood samples that rule out other diseases that may cause the symptoms. At the clinic, they attend a physician's consultation with physical exam. Later, in another apppointment, a physicotherapist assesses their physicial functioning including 6 minutes walking test and grip strength. They also attend a psychologist who conducts short, 30 min neuro-cognitive testing.

Patients receive psychoeducation of the Post Covid-19 condition and individual, tailored support and rehabilitation. They are given the opportunity to take part in group counselling once a week during 6 weeks.

The patients are followed up by nurse telephone calls at 3, 6 and 12 months as well as by questionnaires via a secured website.

The main outcome measure in this study is functional ability as measured by WHODAS2.0.

What researchers measure

Primary outcomes

  1. Change from baseline of WHODAS2.0 questionnaire as measured at 12 months

    Functional ability measured by WHODAS2.0 which is a measure developed by WHO and has 36 items. The minimum value is 0, the maximum value is 100. Higher score means worse functional ability.

    Time frame: 0, 3, 6, and 12 months

Secondary outcomes

  2. Health related quality of life

    15D is a health related quality of life measure developed in Finland and the main quality indicator of Helsinki University Hospital. Its minimum value is 0 and maximum 1. Higher score means better health related quality of life.

  7. Sleep

    ISI (Insomnia Severity Index) has seven questions. The minimum value is 0 and the maximum value is 28. Higher score means more severe insomnia.

    Time frame: 0, 3, 6, and 12 months

  8. SSD-12, somatic symptom disorder

    SSD-12 (Somatic Symptom Disorder-12) has 12 items. The minimum value 0 and the maximum is 48. Higher score means more severe perceptions related to somatic symptoms.

    Time frame: 0, 3, 6, and 12 months
