This qualitative study explores the experiences of medical students involved in clinical work and learning under distant supervision, aiming to understand their adaptation, challenges and learning processes in the context of clinical uncertainty and reduced oversight.

This study employed a constructivist grounded theory (CGT). CGT was chosen for its strength in examining complex social interactions and uncovering emergent themes that are not fully explained by existing theoretical frameworks. Data were collected through 13 semi-structured, in-depth interviews with medical students who actively participated in clinical care under conditions of limited supervision and high responsibility.

Faculty of Medicine, Switzerland.

We conducted interviews with 13 medical students who worked in Mobile SWAB Teams during the COVID-19 pandemic.

Students described a shift from observation to actively taking on a professional role. This experience provided a unique opportunity for medical students to apply their knowledge and skills in real-world settings, develop a sense of autonomy and foster personal growth. Acknowledging the importance of effective communication, teamwork and decision-making in providing patient care, they embraced the concept of self-regulated learning (SRL).

Creating a supportive learning environment that promotes SRL encourages collaboration and enables medical students to take on clinical tasks with increasing autonomy. In our study, working under distant supervision promoted reflection, strengthened communication and supported both clinical development and identity formation. This approach highlights the value of integrating supported responsibility and guided reflection into future models of clinical education.

The recent pandemic caused by SARS-CoV-2 had a profound global impact. While many individuals recovered from COVID-19, some developed long-lasting symptoms that significantly disrupted daily life. The WHO defines this condition as post-COVID-19 condition (PCC). Common symptoms include fatigue, dyspnoea, sleep disturbances and cognitive difficulties. Increasing evidence suggests that PCC is a multifactorial condition, shaped not only by biomedical but also psychological and social factors. This article presents the protocol of the Basel Long COVID Cohort Study (BALCoS), which aims to improve understanding of PCC by capturing clinical, functional and psychosocial aspects through repeated assessments over the course of 1 year.

BALCoS is a prospective, single-site cohort study. Inclusion criteria include either a probable or confirmed history of SARS-CoV-2 infection with persistent symptoms consistent with the WHO definition of PCC, sufficient German language skills and age ≥18 years. At baseline, we collected detailed information on previous SARS-CoV-2 infections, symptom history, reinfections, COVID-19 vaccination status and pre-existing medical conditions. The study includes standardised psychometric assessments, physical performance tests, ecological momentary assessments (EMAs), neurocognitive testing and blood sample collection. Assessments are scheduled at baseline and at 3-month, 6-month and 12-month follow-up. All participants complete psychometric assessments at each time point. Blood samples are only collected at baseline. Neurocognitive testing and physical performance measures are collected at baseline and 12-month follow-up for in-person participants only. Participants who are unable to attend in person complete a remote version of the study, excluding these in-clinic assessments. EMAs are initiated the day after each time point and consist of eight questions over 10 consecutive days. The study is exploratory in nature, with a target sample size of 120 participants. BALCoS is part of the Horizon Europe Long COVID project, a multinational interdisciplinary research consortium integrating mechanistic, clinical and interventional studies.

The study was approved by the Ethics Commission of Northwest and Central Switzerland (BASEC-ID: 2023–00359) and is registered at ClinicalTrials.gov (ID: NCT05781893). All participants provide written informed consent. Study findings will be disseminated through peer-reviewed publications.
