Stillbirth rates, service outcomes and costs of implementing NHS England’s Saving Babies’ Lives care bundle in maternity units in England: A cohort study
2021
To assess implementation of the Saving Babies Lives (SBL) Care Bundle, a collection of practice recommendations in four key areas, to reduce stillbirth in England.
A retrospective cohort study of 463,630 births in 19 NHS Trusts in England using routinely collected electronic data supplemented with case note audit (n = 1,658), and surveys of service users (n = 2,085) and health care professionals (n = 1,064). The primary outcome was stillbirth rate. Outcome rates two years before and after the nominal SBL implementation date were derived as a measure of change over the implementation period. Data were collected on secondary outcomes and process outcomes which reflected implementation of the SBL care bundle.
The total stillbirth rate, declined from 4.2 to 3.4 per 1,000 births between the two time points (adjusted Relative Risk (aRR) 0.80, 95% Confidence Interval (95% CI) 0.70 to 0.91, P<0.001). There was a contemporaneous increase in induction of labour (aRR 1.20 (95%CI 1.18-1.21), p<0.001) and emergency Caesarean section (aRR 1.10 (95%CI 1.07-1.12), p<0.001). The number of ultrasound scans performed (aRR 1.25 (95%CI 1.21-1.28), p<0.001) and the proportion of small for gestational age infants detected (aRR 1.59 (95%CI 1.32-1.92), p<0.001) also increased. Organisations reporting higher levels of implementation had improvements in process measures in all elements of the care bundle. An economic analysis estimated the cost of implementing the care bundle at ~£140 per birth. However, neither the costs nor changes in outcomes could be definitively attributed to implementation of the SBL care bundle.
Implementation of the SBL care bundle increased over time in the majority of sites. Implementation was associated with improvements in process outcomes. The reduction in stillbirth rates in participating sites exceeded that reported nationally in the same timeframe. The intervention should be refined to identify women who are most likely to benefit and minimise unwarranted intervention.
The study was registered on (NCT03231007); www.clinicaltrials.gov.

Cost-effectiveness evidence for strategies to promote or support breastfeeding: a systematic search and narrative literature review
2020
Background
Global health policy recommends exclusive breastfeeding until infants are 6 months. Little is known about the cost-effectiveness of breastfeeding promotion strategies. This paper presents a systematic search and narrative review of economic evaluations of strategies to support or promote breastfeeding. The aim of the review is to bring together current knowledge to guide researchers and commissioners towards potentially cost-effective strategies to promote or support breastfeeding.
Methods
Searches were conducted of electronic databases, including MEDLINE and Scopus, for economic evaluations relevant to breastfeeding, published up to August 2019. Records were screened against pre-specified inclusion/exclusion criteria and quality was assessed using a published checklist. Costs reported in included studies underwent currency conversion and inflation to a single year and currency so that they could be compared. The review protocol was registered on the PROSPERO register of literature reviews (ID, CRD42019141721).
Results
There were 212 non-duplicate citations. Four were included in the review, which generally indicated that interventions were cost-effective. Two studies reported that breastfeeding promotion for low-birth weight babies in critical care is associated with lower costs and greater health benefits than usual care and so is likely to be cost-effective. Peer-support for breastfeeding was associated with longer duration of exclusivity with costs ranging from £19–£107 per additional month (two studies).
Conclusions
There is limited published evidence on the cost-effectiveness of strategies to promote breastfeeding, although the quality of the current evidence is reasonably high. Future studies should integrate evaluations of the effectiveness of strategies with economic analyses.

Background
There is some evidence that incentive-based strategies effectively encourage smoking cessation in the perinatal period. Incentives could be part of policies aiming to increase breastfeeding rates. This systematic review aimed to summarise current evidence to guide researchers and policymakers towards potentially effective incentive-based strategies for increasing breastfeeding.
Methods
Searches of electronic literature databases were conducted (MEDLINE, Scopus, Embase, CINAHL, and PsycInfo) for evaluations of incentive-based strategies to promote breastfeeding published up to August 2024. Identified studies were screened against pre-specified inclusion criteria: studies focusing on promoting or sustaining breastfeeding; an incentive intervention given to mothers or households; a comparator of standard or usual care or an alternative non-incentive intervention; random allocation to treatment group; evaluation of at least one quantitative outcome measure related to breastfeeding. The following were excluded: literature reviews; conference abstracts; protocol papers; animal studies. Key study information was extracted from included records and they were critically appraised using a published checklist (CASP RCT). The results were presented and synthesised narratively. The review protocol was published on the PROSPERO literature review register.
Results
Database searches identified 64 non-duplicate records, and 2 additional records were identified through citation searching of previously published reviews. There were 7 records (from 6 studies) included in the review. Four studies included a total of 260 participants, and the other two studies included a total of 3418 households. Most studies were either conducted in low-income countries (3 of 6) or with low-income mothers in the United States (2 of 6). Some studies reported positive effects of incentives on breastfeeding intention, initiation, prevalence, and duration of exclusive breastfeeding, although others reported neutral findings. Incentives and study designs were heterogeneous, the studies were generally small, and results may not be generalisable to other settings/population groups.
Conclusions
There is some evidence that incentives may improve breastfeeding outcomes, although the quantity and quality of current evidence are both low. Future studies should ensure that sample sizes are sufficiently large and that core breastfeeding outcomes are defined and collected.

ObjectivesTo estimate the number and burden of medication errors associated with prescription information transfer within the National Health Service (NHS) in England and the impact of implementing an interoperable prescription information system (a single digital prescribing record shared across NHS settings) in reducing these errors.MethodsWe constructed a probabilistic mathematical model. We estimated the number of transition medication errors that would be undetected by standard medicines reconciliation, based on published literature, and scaled this up based on the annual number of hospital admissions. We used published literature to estimate the proportion of errors that lead to harm and applied this to the number of errors to estimate the associated burden (healthcare resource use and deaths). Finally, we used reported effect sizes for electronic prescription information sharing interventions to estimate the impact of implementing an interoperable prescription information system on number of errors and resulting harm.ResultsAnnually, around 1.8 million (95% credibility interval (CrI) 1.3 to 2.6 million) medication errors were estimated to occur at hospital transitions in England, affecting approximately 380 000 (95% CrI 260 397 to 539 876) patient episodes. Harm from these errors affects around 31 500 (95% CrI 22 407 to 42 906) patients, with 36 500 (95% CrI 25 093 to 52 019) additional bed days of inpatient care (costing around £17.8 million (95% CrI £12.4 to £24.9 million)) and >40 (95% CrI 9 to 146) deaths. Assuming the implementation of an interoperable prescription information system could reduce errors by 10% and 50%, there could be 180 000–913 000 fewer errors, 3000–15 800 fewer people who experience harm and 4–22 lives saved annually.ConclusionsAn interoperable prescription information system could provide major benefits for patient safety. Likely additional benefits include healthcare professional time saved, improved patient experience and care quality, quicker discharge and enhanced cross-organisational medicines optimisation. Our findings provide vital safety and economic evidence for the case to adopt interoperable prescription information systems.

AbstractObjectiveTo investigate risks of multiple adverse outcomes associated with use of antipsychotics in people with dementia.DesignPopulation based matched cohort study.SettingLinked primary care, hospital and mortality data from Clinical Practice Research Datalink (CPRD), England.PopulationAdults (≥50 years) with a diagnosis of dementia between 1 January 1998 and 31 May 2018 (n=173 910, 63.0% women). Each new antipsychotic user (n=35 339, 62.5% women) was matched with up to 15 non-users using incidence density sampling.Main outcome measuresThe main outcomes were stroke, venous thromboembolism, myocardial infarction, heart failure, ventricular arrhythmia, fracture, pneumonia, and acute kidney injury, stratified by periods of antipsychotic use, with absolute risks calculated using cumulative incidence in antipsychotic users versus matched comparators. An unrelated (negative control) outcome of appendicitis and cholecystitis combined was also investigated to detect potential unmeasured confounding.ResultsCompared with non-use, any antipsychotic use was associated with increased risks of all outcomes, except ventricular arrhythmia. Current use (90 days after a prescription) was associated with elevated risks of pneumonia (hazard ratio 2.19, 95% confidence interval (CI) 2.10 to 2.28), acute kidney injury (1.72, 1.61 to 1.84), venous thromboembolism (1.62, 1.46 to 1.80), stroke (1.61, 1.52 to 1.71), fracture (1.43, 1.35 to 1.52), myocardial infarction (1.28, 1.15 to 1.42), and heart failure (1.27, 1.18 to 1.37). No increased risks were observed for the negative control outcome (appendicitis and cholecystitis). In the 90 days after drug initiation, the cumulative incidence of pneumonia among antipsychotic users was 4.48% (4.26% to 4.71%) versus 1.49% (1.45% to 1.53%) in the matched cohort of non-users (difference 2.99%, 95% CI 2.77% to 3.22%).ConclusionsAntipsychotic use compared with non-use in adults with dementia was associated with increased risks of stroke, venous thromboembolism, myocardial infarction, heart failure, fracture, pneumonia, and acute kidney injury, but not ventricular arrhythmia. The range of adverse outcomes was wider than previously highlighted in regulatory alerts, with the highest risks soon after initiation of treatment.

Cost-effectiveness of interventions for perinatal anxiety and/or depression: a systematic review
2018
ObjectivesAnxiety and/or depression during pregnancy or year after childbirth is the most common complication of childbearing. Economic evaluations of interventions for the prevention or treatment of perinatal anxiety and/or depression (PAD) were systematically reviewed with the aim of guiding researchers and commissioners of perinatal mental health services towards potentially cost-effective strategies.MethodsElectronic searches were conducted on the MEDLINE, PsycINFO and NHS Economic Evaluation and Health Technology Assessment databases in September 2017 to identify relevant economic evaluations published since January 2000. Two stages of screening were used with prespecified inclusion/exclusion criteria. A data extraction form was designed prior to the literature search to capture key data. A published checklist was used to assess the quality of publications identified.ResultsOf the 168 non-duplicate citations identified, 8 studies met the inclusion criteria for the review; all but one focussing solely on postnatal depression in mothers. Interventions included prevention (3/8), treatment (3/8) or identification plus treatment (2/8). Two interventions were likely to be cost-effective, both incorporated identification plus treatment. Where the cost per quality-adjusted life year (QALY) gained was reported, interventions ranged from being dominant (cheaper and more effective than usual care) to costing £39 875/QALY.ConclusionsUncertainty and heterogeneity across studies in terms of setting and design make it difficult to make direct comparisons or draw strong conclusions. However, the two interventions incorporating identification plus treatment of perinatal depression were both likely to be cost-effective. Many gaps were identified in the economic evidence, such as the cost-effectiveness of interventions for perinatal anxiety, antenatal depression or interventions for fathers.PROSPERO registration numberCRD42016051133.

Evidence-based Recovery Colleges: developing a typology based on organisational characteristics, fidelity and funding
2024
Purpose
Recovery Colleges (RCs) have been implemented across England with wide variation in organisational characteristics. The purpose of this study is to describe RCs across England in terms of organisational and student characteristics, fidelity and annual spending, to generate a RC typology based on characteristics and to explore the relationship between characteristics and fidelity.
Methods
All RC in England meeting criteria on recovery orientation, coproduction and adult learning were included. Managers completed a survey capturing characteristics, fidelity and budget. Hierarchical cluster analysis was conducted to identify common groupings and generate an RC typology.
Results
Participants comprised 63 (72%) of 88 RC in England. Fidelity scores were high (median 11, IQR 9–13). Both NHS and strengths-focussed RCs were associated with higher fidelity. The median annual budget was £200,000 (IQR £127,000–£300,000) per RC. The median cost per student was £518 (IQR £275–£840), cost per course designed was £5,556 (IQR £3,000–£9,416) and per course run was £1,510 (IQR £682–£3,030). The total annual budget across England for RCs is an estimated £17.6 m including £13.4 m from NHS budgets, with 11,000 courses delivered to 45,500 students.
Conclusion
Although the majority of RCs had high levels of fidelity, there were sufficiently pronounced differences in other key characteristics to generate a typology of RCs. This typology might prove important for understanding student outcomes and how they are achieved and for commissioning decisions. Staffing and co-producing new courses are key drivers of spending. The estimated budget for RCs was less than 1% of NHS mental health spending.

Estimating the impact of implementing an integrated care management approach with Atrial fibrillation Better Care (ABC) pathway for patients with atrial fibrillation in England from 2020 to 2040
2024
Background
Stroke prevention is central to the management of atrial fibrillation (AF), but there remains a residual risk of adverse outcomes in anticoagulated AF patients. Hence, current guidelines have proposed a more holistic or integrated approach to AF management, based on the Atrial fibrillation Better Care (ABC) pathway, as follows: (A) avoid stroke with anticoagulation; (B) better symptom control with patient-centred symptom directed decisions on rate or rhythm control; and (C) cardiovascular and comorbidity management, including lifestyle factors. There has been no formal healthcare cost analysis from the UK National Health Service (NHS) perspective of ABC pathway implementation to optimize the management of AF. Our aim was to estimate the number of patients with AF in the UK each year up to 2040, their morbidity and mortality, and the associated healthcare costs, and secondly, to estimate improvements in morbidity and mortality of implementing an ABC pathway, and the impact on costs.
Results
In 2020, there were an estimated 1 463 538 AF patients, resulting in £286 million of stroke care and £191 million of care related to bleeds annually. By 2030, it is expected that there will be 2 115 332 AF patients, resulting in £666 million of stroke healthcare and £444 million of healthcare related to bleeds. By 2040, this is expected to rise to 2 856 489 AF patients, with £1096 million of stroke healthcare and £731 million of healthcare related to bleeds for that year. If in 2040 patients are managed on an ABC pathway, this could prevent between 3724 and 18 622 strokes and between 5378 and 26 890 bleeds, and save between 16 131 and 80 653 lives depending on the proportion of patients managed on the pathway. This would equate to cost reductions of between £143.9 million and £719.6 million for the year.
Conclusion
We estimate that there will be a substantial healthcare burden in the UK NHS associated with AF, from strokes, bleeds, and mortality over the next decades. If patients are managed with a holistic or integrated care approach based on the ABC pathway, this could prevent strokes and bleeds that equate to substantial NHS healthcare cost reductions, and save lives.

AbstractObjectivesTo quantify prevalence, harms, and NHS costs in England of problematic oral non-steroidal anti-inflammatory drug (NSAID) prescribing in high risk groups.DesignPopulation based cohort and economic modelling study.SettingEconomic models estimating patient harm associated with NSAID specific hazardous prescribing events, and cost to the English NHS, over a 10 year period, were combined with trends of hazardous prescribing event to estimate national levels of patient harm and NHS costs.ParticipantsEligible participants were prescribed oral NSAIDs and were in five high risk groups: older adults (≥65 years) with no gastroprotection; people who concurrently took oral anticoagulants; or those with heart failure, chronic kidney disease, or a history of peptic ulcer.Main outcome measuresPrevalence of hazardous prescribing events, by each event and overall, discounted quality adjusted life years (QALYs) lost, and cost to the NHS in England of managing harm.ResultsQALY losses and cost increases were observed for each hazardous prescribing event (v no hazardous prescribing event). Mean QALYs per person were between 0.01 (95% credibility interval (CI) 0.01 to 0.02) lower with history of peptic ulcer, to 0.11 (0.04 to 0.19) lower with chronic kidney disease. Mean cost increases ranged from a non-statistically significant £14 (€17; $18) (95% CI −£71 to £98) in heart failure, to a statistically significant £1097 (£236 to £2542) in people concurrently taking anticoagulants. Prevalence of hazardous prescribing events per 1000 patients ranged from 0.11 in people who have had a peptic ulcer to 1.70 in older adults. Nationally, the most common hazardous prescribing event (older adults with no gastroprotection) resulted in 1929 (1416 to 2452) QALYs lost, costing £2.46m (£0.65m to £4.68m). The greatest impact was in people concurrently taking oral anticoagulants: 2143 (894 to 4073) QALYs lost, costing £25.41m (£5.25m to £60.01m). Over 10 years, total QALYs lost were estimated to be 6335 (4471 to 8658) and an NHS cost for England of £31.43m (£9.28m to £67.11m).ConclusionsNSAIDs continue to be a source of avoidable harm and healthcare cost in these five high risk populations, especially in inducing an acute event in people with chronic condition and people taking oral anticoagulants.

Collaborative care can support the treatment of depression in people with long-term conditions, but long-term benefits and costs are unknown.AimsTo explore the long-term (24-month) effectiveness and cost-effectiveness of collaborative care in people with mental-physical multimorbidity.
A cluster randomised trial compared collaborative care (integrated physical and mental healthcare) with usual care for depression alongside diabetes and/or coronary heart disease. Depression symptoms were measured by the symptom checklist-depression scale (SCL-D13). The economic evaluation was from the perspective of the English National Health Service.
191 participants were allocated to collaborative care and 196 to usual care. At 24 months, the mean SCL-D13 score was 0.27 (95% CI, -0.48 to -0.06) lower in the collaborative care group alongside a gain of 0.14 (95% CI, 0.06-0.21) quality-adjusted life-years (QALYs). The cost per QALY gained was £13 069.
In the long term, collaborative care reduces depression and is potentially cost-effective at internationally accepted willingness-to-pay thresholds.Declaration of interestNone.
