In a study published in the journal Nicotine and Tobacco Research , we evaluated the secondary effectiveness outcomes for Quit Genius, a digital clinician-assisted cognitive behavioural therapy (CBT) intervention for smoking cessation. Adult smokers (N=556) were randomly assigned to Quit Genius (n=277), a digital, clinician-assisted CBT intervention or Very Brief Advice (VBA) to stop smoking, an evidence-based, 30-second intervention designed to facilitate quit attempts, coupled with referral to a cessation service (n=279). Participants were offered combination nicotine replacement therapy (patches and gum) tailored to individual nicotine dependence. Analyses (N=530), by intention-to-treat, compared Quit Genius and VBA at 4, 26, and 52 weeks post-quit date.  The primary outcome was self-reported seven-day point prevalence abstinence at 4 weeks post-quit date. Consecutive seven-day point-prevalence abstinence, defined as abstinent at two or more consecutive timepoints, was examined ...

The National Health Service (NHS) 111 helpline was set up to improve access to urgent care in England, efficiency and cost-effectiveness of first-contact health services. Following trusted, authoritative advice is crucial for improved clinical outcomes. In paper published in the journal PLOS ONE , we examined patient and call-related characteristics associated with compliance with advice given in NHS 111 calls.  The importance of health interactions that are not face-to-face has recently been highlighted by COVID-19 pandemic. In this retrospective cohort study, NHS 111 call records were linked to urgent and emergency care services data. We analysed data of 3,864,362 calls made between October 2013 and September 2017 relating to 1,964,726 callers across London. A multiple logistic regression was used to investigate associations between compliance with advice given and patient and call characteristics.  Caller’s action is ‘compliant with advice given if first subsequent service ...

Our new article in Lancet Infectious Diseases discusses why some migrants in Europe are at risk of under-immunisation and show lower vaccination uptake for routine and COVID-19 vaccines. Addressing this issue is critical if we are to address vaccination inequities and meet the goals of WHO's new Immunisation Agenda 2030.  We carried out a systematic review exploring barriers and facilitators of vaccine uptake (categorised using the 5As taxonomy: access, awareness, affordability, acceptance, activation) and sociodemographic determinants of under-vaccination among migrants in the EU and European Economic Area, the UK, and Switzerland.  We identified multiple access barriers—including language, literacy, and communication barriers, practical and legal barriers to accessing and delivering vaccination services, and service barriers such as lack of specific guidelines and knowledge of health-care professionals—for key vaccines including measles-mumps-rubella, diphtheria-pertussis-t...

Multimorbidity, the co-occurrence of two or more chronic conditions, is increasing in prevalence and affecting approximately a third of all adults globally. In the UK, the prevalence of individuals with four or more long-term conditions is projected to increase to 17% by 2035, compared to 9.8% in 2015. Approximately two thirds of this population will have a mental illness such as depression , which is in turn strongly associated with the incidence of a multitude of long-term conditions.  As the number of physical conditions a person increases, the odds of having a mental health disorder increase by almost double for one condition, and six times for more than five conditions. The presence of a mental health comorbidity such as depression is associated with poorer clinical outcomes and quality of life, compared to individuals with physical conditions only. In an article published in the journal PLOS ONE , we summarised the current evidence on the association between depression and un...
