The Tokyo 2020 and Beijing 2022 Olympic Games held during the COVID-19 pandemic: planning, outcomes, and lessons learnt.

The COVID-19 pandemic profoundly affected all mass gatherings for sporting and religious events, causing cancellation, postponement, or downsizing. On March 24, 2020, the Japanese Government, the Tokyo Organising Committee of the Olympic and Paralympic Games, and the International Olympic Committee decided to postpone the Tokyo 2020 Olympic and Paralympic Games until the summer of 2021. With the emergence of SARS-CoV-2, the potential creation of a superspreading event that would overwhelm the Tokyo health system was perceived as a risk. Even with a delayed start date, an extensive scale of resources, planning, risk assessment, communication, and SARS-CoV-2 testing were required for the Games to be held during the COVID-19 pandemic. The effectiveness of various mitigation and control measures, including the availability of vaccines and the expansion of effective testing options, allowed event organisers and the Japanese Government to successfully host the rescheduled 2020 Tokyo Olympic Games from July 23 to Aug 8, 2021 with robust safety plans in place. In February and March, 2022, Beijing hosted the 2022 Winter Olympic Games as scheduled, built on the lessons learnt from the Tokyo Games, and developed specific COVID-19 countermeasure plans in the context of China's national framework for the plan called Zero COVID. Results from the testing programmes at both the Tokyo and Beijing Games show that the measures put in place were effective at preventing the spread of COVID-19 within the Games, and ensured that neither event became a COVID-19-spreading event. The extensive experience from the Tokyo and Beijing Olympic Games highlights that it is possible to organise mass gatherings during a pandemic, provided that appropriate risk assessment, risk mitigation, and risk communication arrangements are in place, leaving legacies for future mass gatherings, public health, epidemic preparedness, and wider pandemic response.

Longitudinal panel data study of self-rated health among migrants in French-speaking Switzerland, 2003-2017.

INTRODUCTION: Studies have documented poorer health among migrants than natives of several European countries, but little is known for Switzerland. We assessed the association between country of birth, socioeconomic factors and self-reported health (SRH) in a prospective cohort of adults living in Lausanne, Switzerland. METHODS: We used the data from the Colaus panel data study for three periods: 2003-2006 (n=6733), 2009-2012 (n=5064) and 2014-2017 (n=4555) corresponding to 35% of the source population. The response variable was SRH. Main explanatory variables were socioeconomic status, educational level, professional status, income, gender, age and years in Switzerland. The main covariate was country of birth, dichotomised as born in Switzerland or not. We specified random effects logistic regressions and used Bayesian methods for the inference. RESULTS: Being born outside of Switzerland was not associated with worse SRH (OR 1.09, 95% CI 0.52 to 2.31). Several other patient variables were, however, predictive of poor health. Educational level was inversely associated with the risk of reporting poor health. Monthly household income showed a gradient where higher income was associated with lower odds of reporting poor SRH, for both for migrants and non-migrants. Migrant women had lower odds of reporting poor SRH than men (OR 0.73, 95% CI 0.55 to 0.98). Migrant people living in couple have less risk of reporting poor SRH than people who live alone and the risk is lower for migrant people living in couple with children (OR 0.66, 95% CI 0.55 to 0.80). DISCUSSION: Migrant status was not associated with poorer SRH. However, differences in SRH were observed based on gender, age and several social determinants of health.

A provider feedback intervention to increase uptake of colorectal cancer screening in a Swiss academic general practice.

Colorectal cancer (CRC) cancer screening uptake is low in our diverse, outpatient teaching clinic. A state-level public screening programme was recently launched that provides faecal immunochemical tests or screening colonoscopy to all citizens aged 50-69 years via mailed invitations, with the possibility of earlier, opportunistic inclusion. Mailed outreach is expected to be rolled out over the next 5 years. In the interim, we aimed to increase CRC screening by accelerating the inclusion of patients into the programme by implementing a provider feedback programme with residents. We used billing reports to define the eligible target population and monthly lists of included patients to track progress. All residents received a standard intervention that provided basic training and communication tools facilitating shared decision making in CRC screening decisions. We then developed and implemented the intervention over 3 Plan-Do-Study-Act cycles in 2 of 4 groups of residents, each with 7 residents and approximately 250 eligible patients. The intervention consisted of individualised reports on the proportion of each resident's patients that had been included in the screening programme and the names of patients who had not yet been included. The first group that received the intervention had included 58 of 232 eligible patients (25%) at 8 months after the feedback intervention and the second group 51 of 249 eligible patients (20%) at 4 months. In comparison, the 2 groups with only the standard intervention had included 32 of 252 (13%) and 27 of 260 (10%) of their patients, respectively, at 11 months after the baseline intervention. These results suggest that provider feedback to medical residents can promote resident self-awareness and increase the proportion of patients included in a public programme when provided in addition to educational interventions.

Difficult patient-doctor encounters in a Swiss university outpatient clinic: cross-sectional study.

INTRODUCTION: Previous research has shown that multiple factors contribute to healthcare providers perceiving encounters as difficult, and are related to both medical and non-medical demands. AIM: To measure the prevalence and to identify predictors of encounters perceived as difficult by medical residents. DESIGN AND SETTING: Cross-sectional study at the Department of Ambulatory Care and Community Medicine (DACCM), a university outpatient clinic with a long tradition of caring for vulnerable patients. METHOD: We identified difficult doctor-patient encounters using the validated Difficult Doctor-Patient Relationship Questionnaire (DDPRQ-10), and characterised patients using the patient's vulnerability grid, a validated questionnaire measuring five domains of vulnerability, both completed by medical residents after each encounter. We used a multiple linear regression model with the outcome variable as the DDPRQ-10 score, controlling for resident characteristics. PARTICIPANTS: We analysed 527 patient encounters performed by all 27 DACCM residents (17 women and 10 men). We asked each medical resident to evaluate 20 consecutive consultations starting on the same date. OUTCOME: One hundred and fifty-seven encounters (29.8%) were perceived as difficult. RESULTS: After adjusting for differences among residents, all five domains of the patient vulnerability grid were independently associated with a difficult encounter: frequent healthcare user; psychological comorbidity; health comorbidity; risky behaviours and a precarious social situation. CONCLUSION: Nearly a third of encounters were perceived as difficult by medical residents in our university outpatient clinic that cares for a high proportion of vulnerable patients. This represents twice the average ratio of difficult encounters in general practice. All five domains of patient vulnerability appear to have partial explanatory power on medical residents' perception of difficult patient encounters.

Hair analysis following chronic smoked-drugs-of-abuse exposure in adults and their toddler: a case report.

INTRODUCTION: Over the past two decades, the study of chronic cocaine and crack cocaine exposure in the pediatric population has been focused on the potential adverse effects, especially in the prenatal period and early childhood. Non-invasive biological matrices have become an essential tool for the assessment of a long-term history of drug of abuse exposure. CASE REPORT: We analyze the significance of different biomarker values in hair after chronic crack exposure in a two-year-old Caucasian girl and her parents, who are self-reported crack smokers. The level of benzoylecgonine, the principal metabolite of cocaine, was determined in segmented hair samples (0 cm to 3 cm from the scalp, and > 3 cm from the scalp) following washing to exclude external contamination. Benzoylecgonine was detectable in high concentrations in the child's hair, at 1.9 ng/mg and 7.04 ng/mg, respectively. Benzoylecgonine was also present in the maternal and paternal hair samples at 7.88 ng/mg and 6.39 ng/mg, and 13.06 ng/mg and 12.97 ng/mg, respectively. CONCLUSION: Based on the data from this case and from previously published poisoning cases, as well as on the experience of our research group, we conclude that, using similar matrices for the study of chronic drug exposure, children present with a higher cocaine concentration in hair and they experience more serious deleterious acute effects, probably due to a different and slower cocaine metabolism. Consequently, children must be not exposed to secondhand crack smoke under any circumstance.
