Investigating the association between recorded smoking cessation interventions and smoking cessation in people living with cardiovascular disease using UK general practice data.
BACKGROUND: Smoking significantly increases the risk of cardiovascular diseases (CVD), yet quitting smoking after diagnosis of CVD can mitigate further negative impacts. However, encouraging smoking cessation remains a challenge for General Practitioners (GPs) with concerns regarding mental health. Since 2004, the UK's Quality and Outcomes Framework (QOF) incentivises GP smoking cessation support. Despite this, a significant proportion of individuals diagnosed with CVD continue to smoke after diagnosis. This study aims to investigate the frequencies and types of smoking cessation interventions offered to people with CVD (defined as coronary heart disease (CHD) and stroke), with and without mental illness, and assess their association with successful cessation. METHODS: This retrospective cohort study examined adults diagnosed with CHD or stroke using the QResearch general practice records database (1996-2019). We evaluated the frequency and types of smoking cessation interventions documented in patients' records, including education, brief interventions, pharmacological support, referrals, and counselling. Logistic regression assessed the relationship between recorded interventions and smoking abstinence rates within the one-year post-index event, considering QOF incentives and mental illness presence. RESULTS: While smoking cessation education was common in general practice settings, prescriptions for nicotine replacement therapy or other evidence-based interventions were comparatively low. CHD and stroke populations showed a significant association between any intervention and smoking cessation within one year (CHD: OR 1.41, 95% CI 1.36-1.45; stroke: OR 1.49, 95% CI 1.43-1.55). Education consistently correlated with higher cessation likelihoods, while other interventions were linked to lower rates. Individuals with common and serious mental illness were less likely to quit, irrespective of intervention. QOF implementation led to increased documentation of advice but not intensive support or treatment, with pre-QOF interventions associated with significantly increased abstinence likelihoods (CHD: OR 5.09, 95% CI 4.84-5.35; stroke: OR 4.44, 95% CI 4.07-4.86). CONCLUSIONS: Financial incentives for GP smoking cessation support outlined in QOF may not suffice to enhance methods that are more efficacious or improve cessation rates, especially among people with mental illness. Practical strategies that provide tangible support and treatment are needed for CVD patients, including those with mental illness, to facilitate successful cessation.
The implementation of a Nationally Enhanced Service incentive for weight management: A longitudinal qualitative study of the perceptions and experiences of UK primary care staff on weight management using normalisation process theory
SummaryIn 2021 a Nationally Enhanced Service (NES) incentive for weight management in primary care was rolled out in England. This paid general practices £11.50 for every eligible referral they made to a weight management programme. We explored primary care staff's perceptions, experiences and attitudes toward the NES by conducting 37 semi‐structured interviews with General Practitioners (GPs), administrative staff and nurses preceding the introduction of the NES (May to September 2021) and 1 year later following its introduction (September to December 2022). Data were analysed using normalisation process theory. The NES for weight management solidified the position of staff already supportive of referring patients to weight management programmes. For staff less supportive of weight management services, the dissonance between the perceived lack of benefit of services and making referrals to services was reduced with referrals becoming more habitual. Facilitators to implementation included the presence of a coherent national policy; having a ‘champion’ explain key aspects; and a financial incentive if framed as benefiting the practice at large. Barriers included a perception that primary care has been shouldered with a complex and difficult health crisis; a worry over workload burdens; and inefficient and unclear referral systems. The implementation of the NES was broadly welcomed and accepted by primary care staff. Interviewees expressed concerns around the acceptance of weight management policies in primary care, the provision of training to raise the topic of weight and whether the responsibility of weight management fell with primary care, public health or with the patient.
An overview of childhood cancer care and outcomes in Egypt: a narrative review
Childhood cancer is an urgent priority in Egypt, owing to a large number of children with cancer, the great need and demand for paediatric oncology services, limited resources/ funds and inferior survival outcomes. Therefore, an overview of the status of childhood cancer care in Egypt and an evidence-based approach towards optimal utilisation of resources/funds to improve this care are needed. This paper summarises key evidence about childhood cancer care and outcomes in Egypt. We conducted a narrative literature review using a structured search strategy of the MEDLINE database through the PubMed interface. All relevant evidence was summarised under five main sub-topics: (1) burden of childhood cancer in Egypt; (2) treatment approaches; (3) health outcomes; (4) costs and cost-effectiveness of treatment; and (5) barriers and facilitators to optimal childhood cancer care. We found high estimates of disease burden of childhood cancer in Egypt. Furthermore, childhood cancer treatment in Egypt is based on either implementing intensity-regulated protocols or adopting international protocols with or without adaptations to local contexts, leading to varying standards of care among the different treating centres. Limited data about the survival outcomes, costs and cost-effectiveness of treatment exist, although high-quality data from retrospective cohort studies were published from a large paediatric oncology centre (Children’s Cancer Hospital Egypt–57357). As Egypt joins the WHO Global Initiative for Childhood Cancers as a focus country, it is prepared to move towards streamlining national efforts to implement a national childhood cancer plan to advance care, improve health outcomes and optimise resource use. Through these efforts, Egypt could become a beacon of hope and a role model to other low- and middle-income countries seeking to improve their childhood cancer care.
Interventions for smokeless tobacco use cessation.
RATIONALE: While combustible tobacco has been the subject of a very large amount of research, smokeless tobacco products receive less attention. Most smokeless tobacco products are very harmful and cause global health inequality. It is therefore important to identify evidence-based cessation aids. OBJECTIVES: To assess the effects of behavioural and pharmacological interventions for smokeless tobacco use cessation. SEARCH METHODS: We searched the following databases from inception to 16 February 2024: Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; Embase; PsycINFO; ClinicalTrials.gov (through CENTRAL); World Health Organisation International Clinical Trials Registry Platform (through CENTRAL). We also searched references of eligible studies. ELIGIBILITY CRITERIA: We included randomised controlled trials (RCTs) recruiting people of any age using smokeless tobacco, regardless of tobacco smoking status. Eligible studies could test any intervention designed to support people to quit smokeless tobacco use, and had to measure abstinence from either all tobacco use or smokeless tobacco use at six months or longer. OUTCOMES: The outcome of interest was abstinence from all tobacco use or from smokeless tobacco use at six months or longer. RISK OF BIAS: We used the Cochrane RoB 1 tool to assess bias in included studies. SYNTHESIS METHODS: We followed standard Cochrane methods for screening and data extraction. We grouped studies by comparisons of eligible interventions and comparators, reporting individual study and pooled effects as appropriate. We used a random-effects Mantel-Haenszel model for analyses of behavioural interventions and a fixed effect Mantel-Haenszel model for analyses of pharmacotherapies to calculate risk ratios (RR) with 95% confidence intervals (CI). We assessed the certainty of evidence using GRADE. INCLUDED STUDIES: We included 43 trials of 20,346 people. Thirty-three trials were conducted in North America, five in India, two in Scandinavia, one in Pakistan and one in Turkey. One study was conducted across multiple sites in Bangladesh, India and Pakistan. Studies tested behavioural interventions (e.g. cessation counselling and brief advice) and pharmacotherapies (e.g. nicotine replacement therapy (NRT), varenicline, and bupropion). We judged five studies to be at low risk of bias overall, 22 at high risk of bias, and the remaining 16 at unclear risk of bias. SYNTHESIS OF RESULTS: We found moderate-certainty evidence of increased quit rates from counselling compared with minimal support (RR 1.76, 95% CI 1.44 to 2.16; I2 = 69%; 21 studies, n = 7417; downgraded because of heterogeneity), brief advice compared with no support (RR 1.24, 95% CI 1.03 to 1.48; I2 = 49%; 7 studies, n = 6271; downgraded because of imprecision), and varenicline compared with placebo (RR 1.35, 95% CI 1.08 to 1.68; I2 = 0%; 2 studies, n = 508; downgraded because of imprecision). We found low-certainty evidence (downgraded because of imprecision and risk of bias) of increased quit rates from NRT compared with placebo or no medication (RR 1.18, 95% CI 1.05 to 1.33; I2 = 39%; 11 studies, n = 2826). Low-certainty evidence (downgraded because of imprecision) did not show benefit from bupropion compared with placebo (RR 0.89, 95% CI 0.54 to 1.44; I2 = 0%; 2 studies, n = 293). We planned subgroup analyses to explore whether smokeless tobacco type affects intervention efficacy, but found insufficient data. AUTHORS' CONCLUSIONS: Cessation counselling, brief advice, and varenicline each probably help more people to quit smokeless tobacco use than minimal or no support, or placebo. NRT may help more people to quit smokeless tobacco use than placebo or no medication. Low-certainty evidence does not currently support bupropion as a smokeless tobacco cessation intervention. Despite the majority of smokeless tobacco users living in South and Southeast Asia, only a minority of trials are conducted in those regions. Future trials should address this imbalance.

Defining success in adult obesity management: A systematic review and framework synthesis of clinical practice guidelines
Obesity is a chronic and complex disease affecting millions of people worldwide. Currently, there is no standard definition of success for the management of obesity. We set out to complete a synthesis of clinical practice guidelines for obesity management for adult populations, aiming to provide both a quantitative descriptive and qualitative analysis of definitions of success in clinical practice guidelines. An electronic search retrieved 4477 references. Sixteen clinical practice guidelines were included after screening and full-text review. We coded definitions of success 147 times across the included guidelines. No standard or explicit definition of success was identified in the guidelines but rather success was implicitly defined. We developed three themes describing how success was defined in the clinical practice guidelines: Knowledge-based decision making; management of expectations; and the perception of control. The review reinforced that success is an inherently subjective and complex concept. Defining success is limited by existing studies that focus on weight loss and would benefit from additional research on different outcomes. Equally, the relationship between people living with obesity and their clinicians should be further explored to understand how defining success is controlled, discussed and framed in a clinical setting.
Enhancing opportunistic recruitment and retention in primary care trials: lessons learned from a qualitative study embedded in the Cranberry for Urinary Tract Infection (CUTI) feasibility trial
Background: Opportunistic recruitment in primary care is challenging due to the inherent unpredictability of incident conditions, and workload and time pressures. Many clinical trials do not recruit to target, leading to equivocal answers to research questions. Learning from the experiences of patients and recruiters to trials of incident conditions has the potential to improve recruitment and retention to future trials, thereby enhancing the quality and impact of research findings. The aim of this research was to learn from the trial experiences of UTI patients and recruiters to the Cranberry for UTI (CUTI) trial, to help plan an adequately powered trial of similar design. Methods: One-to-one semi-structured interviews were embedded within the CUTI feasibility trial, an open-label, randomised feasibility trial of cranberry extract for symptoms of acute, uncomplicated Urinary Tract Infection (UTI) in primary care. Interviews were conducted with a sample of: CUTI trial participants; non-CUTI trial UTI patients; and, recruiters to the CUTI trial. Verbatim transcripts were analysed thematically. Results: Twenty-six patients with UTI and eight recruiters (nurses and GPs) to the CUTI trial were interviewed. Three themes were developed around: reasons for participating in research; barriers to opportunistic recruitment; and, UTI patients’ experiences of trial procedures. Recruiters found that targeted electronic prompts directed at healthcare practitioners based in clinics where patients with incident conditions were likely to present (e.g. minor illness clinic) were more effective than generic prompts (e.g. desk prompts) at filtering patients from their usual clinical pathway to research clinics. Using a script to explain the delayed antibiotic trial group to patients was found to be helpful, and may have served to boost recruitment. For UTI patients, using an electronic diary to rate their symptoms was considered an acceptable medium, and often preferable to using a paper diary or mobile phone application. Conclusions: The use of targeted prompts directed at clinicians, a script to explain trial groups that may be deemed less desirable, and an appropriate diary format for patient-reported outcomes, may help to improve trial recruitment and retention.
Supporting movement and physical activity in people with psychosis: A qualitative exploration of the carer perspective
Background: The need to increase exercise and decrease sedentary behaviour in people diagnosed with psychosis is well-recognised. Aims: We set out to explore caregivers’ perspectives on what supports and prevents physical activity, and how to use carers’ support most effectively. Method: Fourteen caregivers of people diagnosed with psychosis were interviewed. Data were analysed using reflexive thematic analysis, in collaboration with caregivers. Results: Four themes were developed, the first flagging the importance of physical activity, then the others calling for action: (a) Physical inactivity matters: carers are keen to support efforts to increase physical activity in their family or friends because of the enormous impact physical inactivity has on patients, and consequently on carers themselves, such as social isolation and reduction in their own activity. (b) Tell us: without being well-informed about how to help, carers can feel like they are powerless to stop a ‘slow suicide’ or ‘decline’ in patients. (c) Listen to us: through knowing their family and friends well, carers are able to identify important changes in patients and identify successful motivators for them, but these insights can feel uninvited. (d) Ask us: being invited to support activity as a partner in a patients’ care is desirable but having offers of help rejected can “demotivate the motivator.” Conclusions: Caregivers described strong motivation to help patients to be more physically active but can feel that their support is overlooked and under-used by services. Clinical recommendations for carer involvement in physical activity interventions are offered.
Pain experiences during intrauterine device procedures: a thematic analysis of tweets
Introduction In June 2021, high-profile testimonials in the media about pain during intrauterine device (IUD) procedures in the UK prompted significant discussion across platforms including Twitter (subsequently renamed X). We examined a sample of Twitter postings (tweets) to gain insight into public perspectives and experiences. Methods We harvested tweets posted or retweeted on 21–22 June 2021 which contained the search terms coil, intrauterine system, IUD or intrauterine. We analysed the dataset thematically and selected illustrative tweets with the authors’ consent for publication. Results Following deduplication and screening, we included 1431 tweets in our analysis. We identified testimonials with descriptions of varied pain experiences. Twitter users reported that clinicians had not warned them that pain could be severe or explained the options for pain relief. Some raised concerns about pain being minimised or dismissed and linked this to the management of women’s pain in medicine more broadly. Twitter users described connecting to an online community with shared experiences as validating and used this as a springboard for collective action. Conclusions While we acknowledge the limitations of our sample, this study highlights important perspectives and accounts relating to pain during IUD procedures. Our findings attest to the need for strategies to improve the patient experience for those opting for IUD as a clinical priority. Further research should explore IUD users' experiences, expectations and wishes around pain management.
Perspectives and Views of Primary Care Professionals Regarding DiabeText, a New mHealth Intervention to Support Adherence to Antidiabetic Medication in Spain: A Qualitative Study
Background: Antidiabetic medication is effective in preventing diabetes-related complications. However, 40% of type 2 diabetic patients do not adhere to their medication regimes adequately. Brief text messages represent a promising approach to support medication adherence. The aim of this study was to explore the perspectives of primary care professionals (PCPs) concerning the DiabeText intervention, a new text messaging intervention to be developed to support medication adherence in people with type 2 diabetes (T2D) in Mallorca, Spain. Methods: We conducted four focus groups (n = 28) and eight semi-structured interviews with doctors and nurses. Data collection and analysis were carried out by researchers independently following Braun and Clark’s methodology. Results: Three main themes were identified: (1) text messaging interventions have the potential to effectively support diabetes self-management; (2) involving PCPs in the intervention would facilitate its design and implementation; (3) obtaining evidence supporting the cost-effectiveness is a key prerequisite for large-scale implementation of the intervention. PCPs identified barriers and enablers of the design and implementation of the intervention and made suggestions about the content and format of the text messages. Conclusion: The DiabeText intervention is perceived as useful and acceptable by PCPs provided its cost-effectiveness.
Patients’ Views on the Design of DiabeText, a New mHealth Intervention to Improve Adherence to Oral Antidiabetes Medication in Spain: A Qualitative Study
Background: Type 2 Diabetes Mellitus (T2DM) is a long-term condition affecting around 10% of people worldwide. This study aimed to explore T2DM patients' views on DiabeText, a new text messaging intervention to be developed to support adherence to diabetes medication. Methods: A total of four focus groups were conducted with a purposive sample of people with T2DM (n = 34). The data were analysed by multiple researchers independently, and coded using thematic analysis. Results: There were two main themes that emerged: (1) "patients' perspectives on unmet needs for diabetes self-management", and (2) "acceptability and perceived utility of DiabeText". The patients identified a number of barriers for diabetes self-management, including lack of appropriate information and support with diet and physical activity. Support for medication-taking was not perceived as urgently needed, although several barriers were identified (eating outside, traveling, polymedication, dispensation at the pharmacy). The participants anticipated that the proposed intervention would present high levels of patient acceptability and perceived utility as long as its content addresses the barriers that were identified, and includes specific features (short and clear messages, and personalized information). Conclusion: The proposed intervention has the potential to be well accepted and perceived as useful by T2DM patients who require support not only in terms of medication-taking, but more prominently of lifestyle behaviour.
Introduction of point-of-care blood testing in early intervention in psychosis services: effects on physical health screening.
BACKGROUND: There is a significant mortality gap between the general population and people with psychosis. Completion rates of regular physical health assessments for cardiovascular risk in this group are suboptimal. Point-of-care testing (POCT) for diabetes and hyperlipidaemia - providing an immediate result from a finger-prick - could improve these rates. AIMS: To evaluate the impact on patient-clinician encounters and on physical health check completion rates of implementing POCT for cardiovascular risk markers in early intervention in psychosis (EIP) services in South East England. METHOD: A mixed-methods, real-world evaluation study was performed, with 40 POCT machines introduced across EIP teams in all eight mental health trusts in South East England from March to May 2021. Clinician training and support was provided. Numbers of completed physical health checks, HbA1c and lipid panel blood tests completed 6 and 12 months before and 6 months after introduction of POCT were collected for individual patients. Data were compared with those from the South West region, which acted as a control. Clinician questionnaires were administered at 2 and 8 months, capturing device usability and impacts on patient interactions. RESULTS: Post-POCT, South East England saw significant increases in HbA1c testing (odds ratio 2.02, 95% CI 1.17-3.49), lipid testing (odds ratio 2.38, 95% CI 1.43-3.97) and total completed health checks (odds ratio 3.61, 95% CI 1.94-7.94). These increases were not seen in the South West. Questionnaires revealed improved patient engagement, clinician empowerment and patients' preference for POCT over traditional blood tests. CONCLUSIONS: POCT is associated with improvements in the completion and quality of physical health checks, and thus could be a tool to enhance holistic care for individuals with psychosis.
Bridging assessment and treatment for repeat suicidality in prisons: Development and validation of a risk model
Background Suicidal thoughts and behaviours are common in people in prison and associated with poor health outcomes, including suicide, injury and repeat self-harm. Objective To develop and validate a model to stratify risk of repeat suicidality up to 3 months in people in prison. Methods In seven English prisons, we identified 754 people aged over 17 who had been placed on a suicide risk management plan after a self-harm episode or elevated risk. We developed a multivariable model to stratify risk of repeat suicidality at 3 months using routinely collected sociodemographic, clinical and prison-related factors, which were tested using Cox proportional HR models. In a prospective validation sample of 390 people from 13 prisons, we tested this model to assess risk of repeat suicidality at 3 months across a range of performance measures. Findings Of the overall sample of 1144 people in prison (n=966 men or 84%, mean age 33 years), 22% had the outcome of repeat suicidality over 3 months. The final risk model consisted of nine factors, including sex, calendar age and features of recent suicidal behaviour. Calibration and discrimination were similar in both development and validation samples, with O:E ratio=1.09 (95% CI 0.88 to 1.35) and c-statistic=0.66 (95% CI 0.60 to 0.72) in external validation. At a 25% cut-off, sensitivity was 58% (50 to 66) and specificity was 72% (68 to 75) in external validation. The tool (Risk Assessment for people in Prison at risk of Self-harm and Suicide, RAPSS) is available as an online risk calculator at https://oxrisk.com/rapsstrial/. Interpretation A novel assessment approach for repeat suicidality can provide an evidence-based approach to stratify risk and better allocate resources.
Urgent Implementation of Point-of-Care Testing for Group A Streptococcal Infection in a UK Children’s Emergency Department
Objective In late 2022, Western Europe and the United States experienced increased incidences of scarlet fever and life-threatening invasive group A streptococcal (iGAS) infections, especially among children. The outbreak was widely reported in the media in the United Kingdom, leading to increased emergency department (ED) attendances and threatened supplies of antibiotics. Our ED rapidly introduced point-of-care testing for GAS pharyngitis with the aim of rationalizing antibiotic prescribing. Methods We rapidly implemented the use of a molecular-based (polymerase chain reaction) point-of-care test for all children scoring 3 or higher on the McIsaac clinical prediction rule for GAS pharyngitis in children and performed a nested diagnostic accuracy study. The main outcome was concordance or discordance of antibiotic prescribing with the test result. Results Between December 2022 and April 2023, a total of 1,388 patients underwent point-of-care test (45% female, 55% male, median age of 3 y). Based on medical records review, 571 (41%) patients were tested inappropriately (i.e., they did not have documented pharyngitis or similar infection). Antibiotic prescribing was largely appropriate for patients with a diagnosis of pharyngitis or similar presentation, with 20.47% of children with a negative test prescribed antibiotics. Conclusion Antibiotic concordance was acceptable for children with pharyngitis and similar presentations, but nearly half of children without acute respiratory symptoms were tested inappropriately. EDs considering rapid implementation of point-of-care test in similar circumstances should ensure clear guidelines and training around their use so that clinically useful tests are not inadvertently dropped and resources are not wasted.
