General practitioners' wellbeing during the COVID-19 pandemic: Novel methods with social media data.

BACKGROUND: It is difficult to engage busy healthcare professionals in research. Yet during the COVID-19 pandemic, gaining their perspectives has never been more important. OBJECTIVE: To explore social media data for insights into the wellbeing of UK General Practitioners (GPs) during the Covid-19 pandemic. METHODS: We used a combination of search approaches to identify 381 practising UK NHS GPs on Twitter. Using a two stage social media analysis, we firstly searched for key themes from 91,034 retrieved tweets (before and during the pandemic). Following this we used qualitative content analysis to provide in-depth insights from 7145 tweets related to wellbeing. RESULTS: Social media proved a useful tool to identify a cohort of UK GPs; following their tweets longitudinally to explore key themes and trends in issues related to GP wellbeing during the pandemic. These predominately related to support, resources and public perceptions and fluctuations were identified at key timepoints during the pandemic, all achieved without burdening busy GPs. CONCLUSION: Social media data can be searched to identify a cohort of GPs to explore their wellbeing and changes over time.

Effect of sugar-sweetened beverages on oral health: a systematic review and meta-analysis.

BACKGROUND: The impact of consumption of sugar-sweetened beverages (SSB) on health outcomes such as obesity have been studied extensively, but oral health has been relatively neglected. This study aims to assess the association between SSB consumption and dental caries and erosion. METHODS: Systematic review of observational studies. Search strategy applied to Medline, Embase, Cochrane Library, SciELO, LILACS, OpenGrey and HMIC. The risk of bias was assessed using the NIH Quality Assessment Tool for Observational Cross-Sectional Studies and evidence certainty using Grading of Recommendation Assessment Development and Evaluation. Relationships between SSB consumption and caries and erosion were estimated using random-effects model meta- and dose-response analyses. RESULTS: A total of 38 cross-sectional studies were included, of which 26 were rated as high quality. Comparing moderate-to-low consumption, there was significantly increased risk of both caries [OR = 1.57, 95% CI: 1.28-1.92; decayed, missing and filled teeth weighted mean differences (DMFT WMD) = 0.82, 95% CI: 0.38-1.26] and erosion (OR = 1.43, 95% CI: 1.01-2.03). Comparing high-to-moderate consumption, there was further increased risk of caries (OR = 1.53, 95% CI: 1.17-1.99; DMFT WMD = 1.16, 95% CI: -0.59-2.91) and erosion (OR = 3.09, 95% CI: 1.37-6.97). A dose-response gradient and high certainty of evidence was observed for caries. CONCLUSIONS: Increasing SSB consumption is associated with increased risk of dental caries and erosion. Studies were cross-sectional, hence temporality could not be established, but the positive dose-response suggests this relationship is likely to be causal. These findings illustrate the potential benefits to oral health of policies that reduce SSB consumption, including sugar taxation.

Does regulation increase the rate at which doctors leave practice? Analysis of routine hospital data in the English NHS following the introduction of medical revalidation.

BACKGROUND: In 2012, the UK introduced medical revalidation, whereby to retain their licence all doctors are required to show periodically that they are up to date and fit to practise medicine. Early reports suggested that some doctors found the process overly onerous and chose to leave practice. This study investigates the effect of medical revalidation on the rate at which consultants (senior hospital doctors) leave NHS practice, and assesses any differences between the performance of consultants who left or remained in practice before and after the introduction of revalidation. METHODS: We used a retrospective cohort of administrative data from the Hospital Episode Statistics database on all consultants who were working in English NHS hospitals between April 2008 and March 2009 (n = 19,334), followed to March 2015. Proportional hazard models were used to identify the effect of medical revalidation on the time to exit from the NHS workforce, as implied by ceasing NHS clinical activity. The main exposure variable was consultants' time-varying revalidation status, which differentiates between periods when consultants were (a) not subject to revalidation-before the policy was introduced, (b) awaiting a revalidation recommendation and (c) had received a positive recommendation to be revalidated. Difference-in-differences analysis was used to compare the performance of those who left practice with those who remained in practice before and after the introduction of revalidation, as proxied by case-mix-adjusted 30-day mortality rates. RESULTS: After 2012, consultants who had not yet revalidated were at an increased hazard of ceasing NHS clinical practice (HR 2.33, 95% CI 2.12 to 2.57) compared with pre-policy levels. This higher risk remained after a positive recommendation (HR 1.85, 95% CI 1.65 to 2.06) but was statistically significantly reduced (p < 0.001). We found no statistically significant differences in mortality rates between those consultants who ceased practice and those who remained, after adjustment for multiple testing. CONCLUSION: Revalidation appears to have led to greater numbers of doctors ceasing clinical practice, over and above other contemporaneous influences. Those ceasing clinical practice do not appear to have provided lower quality care, as approximated by mortality rates, when compared with those remaining in practice.

How Do Undiagnosed Symptoms of Maternal Psychological Distress During the Postnatal Period Affect Child Developmental Outcomes?

OBJECTIVES: Evidence suggests that maternal psychological distress is an under-diagnosed condition that can have lasting impacts on child outcomes. Models based solely on maternal outcomes have not found screening to be cost-effective. This research explores the effects of self-reported maternal psychological distress on children's language and behavioural development up to the age of 7. METHODS: Using longitudinal survey data from 10,893 families in the UK Millennium Cohort Study, multilevel models are used to explore the differential effects of maternal diagnosed and treated depression versus untreated maternal psychological distress during the postnatal year on longer-term child outcomes. RESULTS: Both diagnosed and treated depression and self-reported maternal psychological distress have detrimental effects on child behavioural development. Behavioural outcomes up to age 5 were better for children of women who received treatment for depression, compared with children those whose mothers' psychological distress was untreated, but this was not maintained to age 7. Little or no evidence of a difference was found between maternal psychological distress and child language development. CONCLUSIONS FOR PRACTICE: This research highlights the lack of effectiveness of existing treatment for maternal psychological distress both to benefit child development and to provide long-term symptom remediation for women. Future research could aim to identify more effective treatments for both women and children.

Women in medicine: historical perspectives and recent trends.

INTRODUCTION: Women now outnumber men in British medical schools. This paper charts the history of women in medicine and provides current demographic trends. SOURCES OF DATA: A historical literature review and routinely collected data from Department of Health and the Health and Social Care Information Centre. AREAS OF AGREEMENT: Clear gender differences are apparent in working practices, including greater likelihood of working part time and specializing in certain areas of medicine. AREAS OF CONTROVERSY: The increasing need to increase activity among the existing medical workforce is timely amidst a changing workforce demographic. GROWING POINTS: Workforce planners, policymakers and Royal Colleges should continue to develop interventions that may reduce disparities in career choices, as well as considering ways to increase participation and activity. AREAS TIMELY FOR DEVELOPING RESEARCH: Further research is needed to explore the cost-effectiveness of existing and future interventions in this field.

Comparing the performance of the Charlson/Deyo and Elixhauser comorbidity measures across five European countries and three conditions.

BACKGROUND: The Charlson and Elixhauser comorbidity measures are commonly used methods to account for patient comorbidities in hospital-level comparisons of clinical quality using administrative data. Both have been validated in North America, but there is less evidence of their performance in Europe and in pooled cross-country data, which are features of the European Collaboration for Healthcare Optimization (ECHO) project. This study compares the performance of the Charlson/Deyo and Elixhauser comorbidity measures in predicting in-hospital mortality using data from five European countries in three inpatient groups. METHODS: Administrative data is used from five countries in 2008-2009 for three indicators commonly used in hospital quality comparisons: mortality rates following acute myocardial infarction, coronary artery bypass graft surgery and stroke. Logistic regression models are constructed to predict mortality controlling for age, gender and the relevant comorbidity measure. Model discrimination is evaluated using c-statistics. Model calibration is evaluated using calibration slopes. Overall goodness-of-fit is evaluated using Nagelkerke's R(2) and the Akaike information criterion. All models are validated internally by using bootstrapping and externally by using the 2009 model parameters to predict mortality in 2008. RESULTS: The Elixhauser measure has better overall predictive ability in terms of discrimination and goodness-of-fit than the Charlson/Deyo measure or the age-sex only model. There is no clear difference in model calibration. These findings are robust to the choice of country, to pooling all five countries and to internal and external validation. CONCLUSIONS: The Elixhauser list contains more comorbidities, which may enable it to achieve better discrimination than the Charlson measure. Both measures achieve similar calibration, so for the purpose of ECHO we judged the Elixhauser measure to be preferable.

Comparing hospital performance within and across countries: an illustrative study of coronary artery bypass graft surgery in England and Spain.

OBJECTIVE: To assess the feasibility, strengths and weaknesses of using administrative data to compare hospital performance across countries, using mortality after coronary artery bypass graft (CABG) surgery as an illustrative example. METHODS: Country specific and pooled models using individual-level data and logistic regression methods assess individual hospital performance using funnel plots accounting for multiple testing. Outcomes are adjusted for age, sex, comorbidities and indicators of patient severity. Data includes patients from all publicly funded hospitals delivering CABG surgery in England and Spain. Inpatient hospital-level standardized mortality rates within 30 days of CABG surgery are calculated for 83 999 CABG patients between 2007 and 2009. RESULTS: Unadjusted national mortality rates are 5% in Spain and 2.3% in England. Country-specific models identified similar patterns of excess mortality 'alerts' and 'alarms' in hospitals in Spain or England. Pooling data from both countries identifies larger numbers of alerts and alarms in Spanish hospitals, and risk-adjustment increased the already large national mortality difference. This was reduced but not eliminated by accounting for lower volume in Spanish hospitals. CONCLUSION: Cross-national comparisons potentially add value by providing international performance benchmarks. Hospital-level analysis across countries can illuminate differences in hospital performance, which might not be identified using country-specific data or incomplete registry data, and can test hypotheses that may explain national differences. Difficulties of making data comparable between countries, however, compound the usual within-country measurement problems.

Socioeconomic inequality in hip replacement in four European countries from 2002 to 2009--area-level analysis of hospital data.

BACKGROUND: Cross-country comparisons of socioeconomic equity in health care typically use sample survey data on general services such as physician visits. This study uses comprehensive administrative data on a specific service: hip replacement. METHODS: We analyse 651 652 publicly funded hip replacements, excluding fractures and accidents, in adults over 35 in Denmark, England, Portugal and Spain from 2002 to 2009. Sub-national administrative areas are split into socioeconomic quintile groups comprising approximately one-fifth of the national population. Area-level Poisson regression with Huber-White standard errors is used to calculate age-sex standardised hip replacement rates by quintile group, together with gaps and ratios between richest and poorest groups (Q5 and Q1) and the middle group (Q3). RESULTS: We find pro-rich-area inequality in England (2009 Q5/Q1 ratio 1.35 [CI 1.25-1.45]) and Spain (2009 Q5/Q1 ratio 1.43 [CI 1.17-1.70]), pro-poor-area inequality in Portugal (2009 Q5/Q1 ratio 0.67 [CI 0.50-0.83]) and no significant inequality in Denmark. Pro-rich-area inequality increased over time in England and Spain but not significantly. Within-country differences between socioeconomic quintile groups are smaller than between-country differences in general population averages: hip replacement rates are substantially lower in Portugal and Spain (8.6 and 7.4 per 10 000 in 2009) than England and Denmark (20.2 and 27.8 per 10 000 in 2009). CONCLUSION: Despite limitations regarding individual-level inequality and area heterogeneity, analysis of area-level data on publicly funded hospital activity can provide useful cross-country comparisons and longitudinal monitoring of socioeconomic inequality in specific health services. Although this kind of analysis cannot provide definitive answers, it can raise important questions for decision makers.

Examining the hospital costs of children born into relative deprivation in England.

OBJECTIVE: To examine the association between being born into relative deprivation and hospital costs during childhood. DESIGN: Retrospective cohort study. METHODS: We created a birth cohort using Hospital Episode Statistics for children born in NHS hospitals in 2003/2004. The Index of Multiple Deprivation (IMD) rank at birth was missing from 75% of the baby records, so we linked mother and baby records to obtain the IMD decile from the mother's record. We aggregated and costed each child's hospital inpatient admissions, and outpatient and emergency department (ED) attendances up to 15 years of age. We used 2019/2020 NHS tariffs to assign costs. We constructed an additional cohort, all children born in 2013/2014, to explore any changes over time, comparing the utilisation and costs up to 5 years of age. RESULTS: Our main cohort comprised 567 347 babies born in 2003/2004, of which we could include 91%. Up to the age of 15 years, children born into the most deprived areas used more hospital services than those born in the least deprived, reflected in higher costs of inpatient, outpatient and ED care. The highest costs and greatest differences are in the year following birth. Comparing this with the later cohort (up to age 5 years), the average cost per child increased across all deprivation deciles, but differences between the most and least deprived deciles appeared to narrow slightly. CONCLUSIONS: Healthcare utilisation and costs are consistently higher for children who are born into the most deprived areas compared with the least.

Mixed Methods EvAluation of the high-volume low-complexity Surgical hUb pRogrammE (MEASURE): a mixed methods study protocol.

INTRODUCTION: The waiting list for elective surgery in England recently reached over 7.8 million people and waiting time targets have been missed since 2010. The high-volume low complexity (HVLC) surgical hubs programme aims to tackle the backlog of patients awaiting elective surgery treatment in England. This study will evaluate the impact of HVLC surgical hubs on productivity, patient care and the workforce. METHODS AND ANALYSIS: This 4-year project consists of six interlinked work packages (WPs) and is informed by the Consolidated Framework for Implementation Research. WP1: Mapping current and future HVLC provision in England through document analysis, quantitative data sets (eg, Hospital Episodes Statistics) and interviews with national service leaders. WP2: Exploring the effects of HVLC hubs on key performance outcomes, primarily the volume of low-complexity patients treated, using quasi-experimental methods. WP3: Exploring the impact and implementation of HVLC hubs on patients, health professionals and the local NHS through approximately nine longitudinal, multimethod qualitative case studies. WP4: Assessing the productivity of HVLC surgical hubs using the Centre for Health Economics NHS productivity measure and Lord Carter's operational productivity measure. WP5: Conducting a mixed-methods appraisal will assess the influence of HVLC surgical hubs on the workforce using: qualitative data (WP3) and quantitative data (eg, National Health Service (NHS) England's workforce statistics and intelligence from WP2). WP6: Analysing the costs and consequences of HVLC surgical hubs will assess their achievements in relation to their resource use to establish value for money. A patient and public involvement group will contribute to the study design and materials. ETHICS AND DISSEMINATION: The study has been approved by the East Midlands-Nottingham Research Ethics Committee 23/EM/0231. Participants will provide informed consent for qualitative study components. Dissemination plans include multiple academic and non-academic outputs (eg, Peer-reviewed journals, conferences, social media) and a continuous, feedback-loop of findings to key stakeholders (eg, NHS England) to influence policy development.

The psychometric properties of the subscales of the GHQ-28 in a multi-ethnic maternal sample: results from the Born in Bradford cohort.

BACKGROUND: Poor maternal mental health can impact on children's development and wellbeing; however, there is concern about the comparability of screening instruments administered to women of diverse ethnic origin. METHODS: We used confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) to examine the subscale structure of the GHQ-28 in an ethnically diverse community cohort of pregnant women in the UK (N = 5,089). We defined five groups according to ethnicity and language of administration, and also conducted a CFA between four groups of 1,095 women who completed the GHQ-28 both during and after pregnancy. RESULTS: After item reduction, 17 of the 28 items were considered to relate to the same four underlying concepts in each group; however, there was variation in the response to individual items by women of different ethnic origin and this rendered between group comparisons problematic. The EFA revealed that these measurement difficulties might be related to variation in the underlying concepts being measured by the factors. CONCLUSIONS: We found little evidence to recommend the use of the GHQ-28 subscales in routine clinical or epidemiological assessment of maternal women in populations of diverse ethnicity.

Using evidence to meet population healthcare needs: A UK perspective.

For over 30 years, researchers have questioned the standard practice of planning the health workforce, with relatively little effect on policy. The authors of this commentary find it extremely refreshing and thoroughly heartening to see their Canadian colleagues making new attempts to change the way that the health workforce is planned and structured. In this commentary, the authors discuss what is meant by healthcare "needs" and the traditionally poor use of data in healthcare planning, and they support Tomblin Murphy and MacKenzie's call for proper evaluation of healthcare resources interventions.

General practitioner well-being during the COVID-19 pandemic: a qualitative interview study.

OBJECTIVES: The COVID-19 pandemic presented new challenges for general practitioners' (GPs') mental health and well-being, with growing international evidence of its negative impact. While there has been a wide UK commentary on this topic, research evidence from a UK setting is lacking. This study sought to explore the lived experience of UK GPs during COVID-19, and the pandemic's impact on their psychological well-being. DESIGN AND SETTING: In-depth qualitative interviews, conducted remotely by telephone or video call, with UK National Health Service GPs. PARTICIPANTS: GPs were sampled purposively across three career stages (early career, established and late career or retired GPs) with variation in other key demographics. A comprehensive recruitment strategy used multiple channels. Data were analysed thematically using Framework Analysis. RESULTS: We interviewed 40 GPs; most described generally negative sentiment and many displayed signs of psychological distress and burnout. Causes of stress and anxiety related to personal risk, workload, practice changes, public perceptions and leadership, team working and wider collaboration and personal challenges. GPs described potential facilitators of their well-being, including sources of support and plans to reduce clinical hours or change career path, and some described the pandemic as offering a catalyst for positive change. CONCLUSIONS: A range of factors detrimentally affected the well-being of GPs during the pandemic and we highlight the potential impact of this on workforce retention and quality of care. As the pandemic progresses and general practice faces continued challenges, urgent policy measures are now needed.

A Comparative Analysis of Anticancer Drug Appraisals Including Managed Entry Agreements in South Korea and England.

OBJECTIVES: This study aimed to compare appraisal decisions about anticancer drugs between the health technology assessment (HTA) agencies in Korea and England, and investigate whether the decisions and supporting evidence are comparable. METHODS: This study identified 49 anticancer drugs listed by the Korean Ministry of Health and Welfare between January 2014 and December 2019. Of those, 46 anticancer drugs for 58 indications were included for analysis. Official appraisal documents from both countries for 58 drug-indication pairs were compared and assessed in terms of clinical and economic evidence. Evidence items and their groups for analysis were predefined. RESULTS: Three-quarters of cases were recommended with managed entry agreements (MEAs) in England and three-fifths in Korea. Finance-based MEA types were most common in both countries. Korean and English authorities made consistent decisions in 48 cases (83%) when classifying decisions as 'recommended' and 'not recommended', while the degree of agreement lowered to 16 cases (28%) when subdividing decisions according to MEA types. When the evidence base was identical, their decisions were more likely to be consistent. Regarding clinical evidence, while the majority of cases referred to the same pivotal studies, differences between the committees' recognized comparators and the appraisal date caused discrepancies in decisions. Economic evidence, including incremental cost-effectiveness ratio (ICER) estimates, was identical in only 12 cases (21%), which contributed to discrepancies. CONCLUSION: England relies on economic evaluation, with increasing use of data collection agreements, in contrast with Korea's new procedure exempting companies from providing economic evaluation. While there is possibility for international cooperation in the assessment of clinical evidence, transferability issues exist, particularly with regard to economic evidence.

Exploring gender differences in uptake of GP partnership roles: a qualitative mixed-methods study.

BACKGROUND: The unadjusted gender pay gap in general practice is reported to be 33.5%. This reflects partly the differential rate at which women become partners, but evidence exploring gender differences in GPs' career progression is sparse. AIM: To explore factors affecting uptake of partnership roles, focusing particularly on gender differences. DESIGN AND SETTING: Convergent mixed-methods research design using data from UK GPs. METHOD: Secondary analysis of qualitative interviews and social media analysis of UK GPs' Twitter commentaries, which informed the conduct of asynchronous online focus groups. Findings were combined using methodological triangulation. RESULTS: The sample comprised 40 GP interviews, 232 GPs tweeting about GP partnership roles, and seven focus groups with 50 GPs. Factors at individual, organisational, and national levels influence partnership uptake and career decisions of both men and women GPs. Desire for work-family balance (particularly childcare responsibilities) presented the greatest barrier, for both men and women, as well as workload, responsibility, financial investment, and risk. Greater challenges were, however, reported by women, particularly regarding balancing work-family lives, as well as prohibitive working conditions (including maternity and sickness pay) and discriminatory practices perceived to favour men and full-time GPs. CONCLUSION: There are some long-standing gendered barriers that continue to affect the career decisions of women GPs. The relative attractiveness of salaried, locum, or private roles in general practice appears to discourage both men and women from partnerships presently. Promoting positive workplace cultures through strong role models, improved flexibility in roles, and skills training could potentially encourage greater uptake.

The effects of computerised decision support systems on nursing and allied health professional performance and patient outcomes: a systematic review and user contextualisation.

Background: Computerised decision support systems (CDSS) are widely used by nurses and allied health professionals but their effect on clinical performance and patient outcomes is uncertain. Objectives: Evaluate the effects of clinical decision support systems use on nurses', midwives' and allied health professionals' performance and patient outcomes and sense-check the results with developers and users. Eligibility criteria: Comparative studies (randomised controlled trials (RCTs), non-randomised trials, controlled before-and-after (CBA) studies, interrupted time series (ITS) and repeated measures studies comparing) of CDSS versus usual care from nurses, midwives or other allied health professionals. Information sources: Nineteen bibliographic databases searched October 2019 and February 2021. Risk of bias: Assessed using structured risk of bias guidelines; almost all included studies were at high risk of bias. Synthesis of results: Heterogeneity between interventions and outcomes necessitated narrative synthesis and grouping by: similarity in focus or CDSS-type, targeted health professionals, patient group, outcomes reported and study design. Included studies: Of 36,106 initial records, 262 studies were assessed for eligibility, with 35 included: 28 RCTs (80%), 3 CBA studies (8.6%), 3 ITS (8.6%) and 1 non-randomised trial, a total of 1318 health professionals and 67,595 patient participants. Few studies were multi-site and most focused on decision-making by nurses (71%) or paramedics (5.7%). Standalone, computer-based CDSS featured in 88.7% of the studies; only 8.6% of the studies involved 'smart' mobile or handheld technology. Care processes - including adherence to guidance - were positively influenced in 47% of the measures adopted. For example, nurses' adherence to hand disinfection guidance, insulin dosing, on-time blood sampling, and documenting care were improved if they used CDSS. Patient care outcomes were statistically - if not always clinically - significantly improved in 40.7% of indicators. For example, lower numbers of falls and pressure ulcers, better glycaemic control, screening of malnutrition and obesity, and accurate triaging were features of professionals using CDSS compared to those who were not. Evidence limitations: Allied health professionals (AHPs) were underrepresented compared to nurses; systems, studies and outcomes were heterogeneous, preventing statistical aggregation; very wide confidence intervals around effects meant clinical significance was questionable; decision and implementation theory that would have helped interpret effects - including null effects - was largely absent; economic data were scant and diverse, preventing estimation of overall cost-effectiveness. Interpretation: CDSS can positively influence selected aspects of nurses', midwives' and AHPs' performance and care outcomes. Comparative research is generally of low quality and outcomes wide ranging and heterogeneous. After more than a decade of synthesised research into CDSS in healthcare professions other than medicine, the effect on processes and outcomes remains uncertain. Higher-quality, theoretically informed, evaluative research that addresses the economics of CDSS development and implementation is still required. Future work: Developing nursing CDSS and primary research evaluation. Funding: This project was funded by the National Institute for Health and Care Research (NIHR) Health and Social Care Delivery Research programme and will be published in Health and Social Care Delivery Research; 2023. See the NIHR Journals Library website for further project information. Registration: PROSPERO [number: CRD42019147773].

Computerised decision support systems (CDSS) are software or computer-based technologies providing advice to professionals making clinical decisions ­ for example, which patients to treat first in emergency departments. CDSS improve some doctors' decisions and patients' outcomes, but we don't know if they improve nurses', midwives' and therapists' or other staff decisions and patient outcomes. Research into, and health professionals' use of, technology ­ for example, in video consultations ­ has grown since the last relevant systematic review in 2009. We systematically searched electronic databases for research measuring how well nurses, midwifes and other therapists/staff followed CDSS advice, how CDSS influence their decisions, how safe CDSS are, and their financial costs and benefits. We interviewed CDSS users and developers and some patient representatives from a general practice to help understand our findings. Of 35 relevant studies ­ from 36,106 initially found ­ most (71%) focused on nurses. Just over half (57%) involved hospital-based staff, and three-quarters (75%) were from richer countries like the USA or the UK. Research quality had not noticeably improved since 2009 and all studies were at risk of potentially misleading readers. CDSS improved care in just under half (47%) of professional behaviours, such as following hand-disinfection guidance, working out insulin doses, and sampling blood on time. Patient care ­ judged using outcomes like falls, pressure ulcers, diabetes control and triage accuracy ­ was better in 41% of the care measured. There wasn't enough evidence to judge CDSS safety or the financial costs and benefits of systems. CDSS can improve some nursing and therapist decisions and some patient outcomes. Studies mostly measure different behaviours and outcomes, making comparing them hard. Theories explaining or predicting how decision support systems might work are not used enough when designing, implementing or evaluating CDSS. More research into the financial costs and benefits of CDSS and higher-quality evidence of their effects are still needed. Whether decision support for nurses, midwives and other therapists reliably improves decision-making remains uncertain.

Cost-effectiveness of acupuncture for irritable bowel syndrome: findings from an economic evaluation conducted alongside a pragmatic randomised controlled trial in primary care.

BACKGROUND: There is insufficient evidence to determine whether acupuncture is a cost-effective treatment for irritable bowel syndrome. The objective of this study is to assess the cost-effectiveness of acupuncture as an adjunct to usual care versus usual care alone for the treatment of Irritable Bowel Syndrome (IBS). METHODS: Cost-utility analysis conducted alongside a pragmatic, multicentre, randomised controlled trial. 233 patients with irritable bowel syndrome were randomly allocated to either acupuncture plus usual care, or usual care alone. Cost-effectiveness outcomes are expressed in terms of incremental cost per quality adjusted life year (QALY) at one year after randomisation. Costs were estimated from the UK National Health Service perspective for a time horizon of one year. Cost-utility ratios were estimated based on complete case analysis for the base case analysis, where only patients with available EQ-5D and cost data were included. Sensitivity analyses comprised a multiple imputation approach for missing data and a subgroup analysis for the more severe cases of IBS. RESULTS: The base case analysis showed acupuncture to be marginally more effective than usual care (gain of 0.0035 QALYs, 95% CI: -0.00395 to 0.0465) and more expensive (incremental cost of £218 per patient (95% CI: 55.87 to 492.87) resulting in an incremental cost-effectiveness ratio of approximately £62,500. Sensitivity analysis using multiple imputation for missing data resulted in acupuncture appearing less effective and more costly than usual care, so usual care is dominant. Subgroup analysis selecting the most severe cases of IBS (Symptom Severity Score of over 300) suggested that acupuncture may be a cost-effective treatment option for this group, with a cost-per-QALY of £6,500. CONCLUSIONS: Acupuncture as an adjunct to usual care is not a cost-effective option for the whole IBS population; however it may be cost-effective for those with more severe irritable bowel syndrome.

Acupuncture for irritable bowel syndrome: primary care based pragmatic randomised controlled trial.

BACKGROUND: Acupuncture is used by patients as a treatment for irritable bowel syndrome (IBS) but the evidence on effectiveness is limited. The purpose of the study was to evaluate the effectiveness of acupuncture for irritable bowel syndrome in primary care when provided as an adjunct to usual care. DESIGN: A two-arm pragmatic randomised controlled trial. SETTING: Primary care in the United Kingdom. PATIENTS: 233 patients had irritable bowel syndrome with average duration of 13 years and score of at least 100 on the IBS Symptom Severity Score (SSS). INTERVENTIONS: 116 patients were offered 10 weekly individualised acupuncture sessions plus usual care, 117 patients continued with usual care alone. MEASUREMENTS: Primary outcome was the IBS SSS at three months, with outcome data collected every three months to 12 months. RESULTS: There was a statistically significant difference between groups at three months favouring acupuncture with a reduction in IBS Symptom Severity Score of -27.43 (95% CI: -48.66 to -6.21, p=0.012). The number needed to treat for successful treatment (≥50 point reduction in the IBS SSS) was six (95% CI: 3 to 17), based on 49% success in the acupuncture group vs. 31% in the control group, a difference between groups of 18% (95% CI: 6% to 31%). This benefit largely persisted at 6, 9 and 12 months. CONCLUSIONS: Acupuncture for irritable bowel syndrome provided an additional benefit over usual care alone. The magnitude of the effect was sustained over the longer term. Acupuncture should be considered as a treatment option to be offered in primary care alongside other evidenced based treatments. TRIAL REGISTRATION: Current Controlled Trials ISRCTN08827905.

Do risk factors for post-partum smoking relapse vary according to marital status?

We aimed to examine associations between factors readily obtainable in health care settings and post-partum smoking relapse in women of differing marital status. We analysed data on 1,829 mothers in the Millennium Cohort Study who reported quitting smoking during their pregnancy using multivariate logistic regression. We analysed single, married and cohabiting women separately. Fifty-seven percent of mothers who quit during pregnancy had relapsed at 9 months. The risk of relapse was highest for single women, followed by cohabiting, then married women. Higher parity and not managing financially were associated with relapse for single women. For married women the greatest risk of relapse was associated with having a partner who also relapsed. Women whose husbands continued to smoke had an increased risk of relapse but those whose husbands had sustained a quit were protected. Other significant risk factors were not breastfeeding, having other children and drinking at moderate frequencies. A similar pattern was seen for cohabiting women, except that having a partner who quit but then relapsed did not appear to confer an additional risk. Drinking at moderate intervals (only) was associated with relapse but breastfeeding and parity were not. The association between married couple relapse was not evident when only the husband's smoking status during the pregnancy was considered, indicating that partner follow-up is important post-partum. Risk factors for relapse appear to differ according to marital status. A 'one size fits all' package of post-partum relapse prevention is unlikely to be an appropriate intervention strategy.

Does the presence of general practitioners in emergency departments affect quality and safety in English NHS hospitals? A retrospective observational study.

OBJECTIVES: Emergency departments (EDs) in NHS hospitals in England have faced considerable increases in demand over recent years. Most hospitals have developed general practitioner services in emergency departments (GPEDs) to treat non-emergency patients, aiming to relieve pressure on other staff and to improve ED efficiency and patient experience. We measured the impact of GPED services on patient flows, health outcomes and ED workload. DESIGN: Retrospective observational study. Differences in GPED service availability across EDs and time of day were used to identify the causal effect of GPED, as patients attending the ED at the same hour of the day are quasi-randomly assigned to treatment or control groups based on their local ED's service availability. PARTICIPANTS: Attendances to 40 EDs in English NHS hospitals from April 2018 to March 2019, 4 441 349 observations. PRIMARY AND SECONDARY OUTCOMES MEASURED: Outcomes measured were volume of attendances, 'non-urgent' attendances, waiting times over 4 hours, patients leaving without being treated, unplanned reattendances within 7 days, inpatient admissions and 30-day mortality. RESULTS: We found a small, statistically significant reduction in unplanned reattendances within 7 days (OR 0.968, 95% CI 0.948 to 0.989), equivalent to 302 fewer reattendances per year for the average ED. The clinical impact of this was judged to be negligible. There was no detectable impact on any other outcome measure. CONCLUSIONS: We found no adverse effects on patient outcomes; neither did we find any evidence of the hypothesised benefits of placing GPs in emergency settings beyond a marginal reduction in reattendances that was not considered clinically significant.
