Impact on maternity professionals of novel approaches to clinical audit feedback

We compared three approaches to feedback of clinical audit findings relating to miscarriage in 15 Scottish maternity services (printed report alone; report plus Action Planning Letter; report plus face-to-face Facilitated Action Planning). We surveyed clinicians to measure Theory of Planned Behaviour constructs (in the context of two audit criteria) before and after feedback (n=253) and assessed perceptions of the audit through in-depth interviews (n=17). Pre-feedback, clinicians had positive attitudes and strong subjective norms and intentions to comply, although perceived behavioural control was lower. Generally, positive attitudes, subjective norms and intentions increased after feedback but for one of the two criteria (providing a 7-day miscarriage service), perceived behavioural control decreased. No changes over time reached statistical significance and analysis of covariance (adjusting for pre-feedback scores) showed no consistent relationships between method of feedback and post-feedback construct scores. Interviews revealed positive perceptions of audit but frustration at lack of capacity to implement changes. While interventions which increased intensity of feedback proved feasible and acceptable to clinicians, we were unable to demonstrate that they increased intention to comply with audit criteria.This study was funded by NHS Quality Improvement Scotland

Dowsing for Knowledge: Probing the Depth of Arsenic Awareness in Rural Newfoundland to Effect Change in Policy and Health Outcomes

Background: Arsenic is an odourless, colourless and tasteless carcinogen that can contaminate well-water. Research in Nova Scotia suggests that well-owners misunderstand the issues and risks related to arsenic and do not take necessary precautions. Rationale: Given that no similar study has occurred in Newfoundland, we examined knowledge gaps about arsenic and related water safety issues among well owners in three rural Newfoundland jurisdictions affected by arsenic (Cormack, New World Island, Gander Bay) and one control area unaffected by arsenic (Codroy Valley). Research Methodology & Approach: We mailed 1380 semi-structured surveys to the four regions, aiming to collect 100 surveys. Results: We received 247 responses (17.8% response rate). A very low response rate from Cormack (n=2) meant the community could not be included in most analyses. We conducted descriptive analyses and Chi Squares in SPSS. Discussion: While the majority of respondents in New World Island had previously tested their water for arsenic, most in Gander Bay and the Codroy Valley had not. Some respondents listed ServiceNL as their go-to tester for arsenic despite the fact that the organization can only test for coliforms, and some respondents also mentioned using sensory cues and ineffective purification strategies (e.g. boiling, using a Brita filter). Conclusion & Recommendations: This study revealed encouraging and concerning results that are informative for both the public and policymakers. We recommend the provincial government develop a new online well-water safety resource, devise strategies to clarify the limitations of ServiceNL water testing, and facilitate citizens’ access to affordable water tests for arsenic

Effect of hands-on interprofessional simulation training for local emergencies in Scotland:the THISTLE stepped-wedge design randomised controlled trial

OBJECTIVE: To assess whether the implementation of an intrapartum training package (PROMPT (PRactical Obstetric Multi-Professional Training)) across a health service reduced the proportion of term babies born with Apgar score <7 at 5 min (<75mins). // DESIGN: Stepped-wedge cluster randomised controlled trial. SETTING: Twelve randomised maternity units with ≥900 births/year in Scotland. Three additional units were included in a supplementary analysis to assess the effect across Scotland. The intervention commenced in March 2014 with follow-up until September 2016. // INTERVENTION: The PROMPT training package (Second edition), with subsequent unit-level implementation of PROMPT courses for all maternity staff. // MAIN OUTCOME MEASURES: The primary outcome was the proportion of term babies with Apgar<75mins. // RESULTS: 87 204 eligible births (99.2% with an Apgar score), of which 1291 infants had an Apgar<75mins were delivered in the 12 randomised maternity units. Two units did not implement the intervention. The overall Apgar<75mins rate observed in the 12 randomised units was 1.49%, increasing from 1.32% preintervention to 1.59% postintervention. Once adjusted for a secular time trend, the 'intention-to-treat' analysis indicated a moderate but non-significant reduction in the rate of term babies with an Apgar scores <75mins following PROMPT training (OR=0.79 95%CI(0.63 to 1.01)). However, some units implemented the intervention earlier than their allocated step, whereas others delayed the intervention. The content and authenticity of the implemented intervention varied widely at unit level. When the actual date of implementation of the intervention in each unit was considered in the analysis, there was no evidence of improvement (OR=1.01 (0.84 to 1.22)). No intervention effect was detected by broadening the analysis to include all 15 large Scottish maternity units. Units with a history of higher rates of Apgar<75mins maintained higher Apgar rates during the study (OR=2.09 (1.28 to 3.41)) compared with units with pre-study rates aligned to the national rate. // CONCLUSIONS: PROMPT training, as implemented, had no effect on the rate of Apgar <75mins in Scotland during the study period. Local implementation at scale was found to be more difficult than anticipated. Further research is required to understand why the positive effects observed in other single-unit studies have not been replicated in Scottish maternity units, and how units can be best supported to locally implement the intervention authentically and effectively

How website users segment a city: The geography of housing search in London

This paper explores spatial patterns of housing search in London, using data generated by users of the UK's most popular real estate portal. By focusing on the variable geographies of ‘search extent’, it attempts to make a contribution to a long line of studies focused on understanding the fragmented geography of metropolitan housing markets. It also builds upon more recent work in economics on the utility of user-generated search data. After introducing our approach, we discuss the background to housing search and the wider emergence of ‘search’ as an object of study. We then provide further details on the data and methodology before exploring the spatial and sectoral characteristics of search in London. The results suggest that there is much to be gained by incorporating search studies into housing market analysis and that there is significant potential for future work in this area

UKMenCar4: A cross-sectional survey of asymptomatic meningococcal carriage amongst UK adolescents at a period of low invasive meningococcal disease incidence.

Carriage of Neisseria meningitidis, the meningococcus, is a prerequisite for invasive meningococcal disease (IMD), a potentially devastating infection that disproportionately afflicts infants and children. Humans are the sole known reservoir for the meningococcus, and it is carried asymptomatically in the nasopharynx of ~10% of the population. Rates of carriage are dependent on age of the host and social and behavioural factors. In the UK, meningococcal carriage has been studied through large, multi-centre carriage surveys of adolescents in 1999, 2000, and 2001, demonstrating carriage can be affected by immunisation with the capsular group C meningococcal conjugate vaccine, inducing population immunity against carriage. Fifteen years after these surveys were carried out, invasive meningococcal disease incidence had declined from a peak in 1999.  The UKMenCar4 study was conducted in 2014/15 to investigate rates of carriage amongst the adolescent population during a period of low disease incidence. The protocols and methodology used to perform UKMenCar4, a large carriage survey, are described here

Changes in serogroup and genotype prevalence among carried meningococci in the United Kingdom during vaccine implementation.

BACKGROUND: Herd immunity is important in the effectiveness of conjugate polysaccharide vaccines against encapsulated bacteria. A large multicenter study investigated the effect of meningococcal serogroup C conjugate vaccine introduction on the meningococcal population. METHODS: Carried meningococci in individuals aged 15-19 years attending education establishments were investigated before and for 2 years after vaccine introduction. Isolates were characterized by multilocus sequence typing, serogroup, and capsular region genotype and changes in phenotypes and genotypes assessed. RESULTS: A total of 8462 meningococci were isolated from 47 765 participants (17.7%). Serogroup prevalence was similar over the 3 years, except for decreases of 80% for serogroup C and 40% for serogroup 29E. Clonal complexes were associated with particular serogroups and their relative proportions fluctuated, with 12 statistically significant changes (6 up, 6 down). The reduction of ST-11 complex serogroup C meningococci was probably due to vaccine introduction. Reasons for a decrease in serogroup 29E ST-254 meningococci (from 1.8% to 0.7%) and an increase in serogroup B ST-213 complex meningococci (from 6.7% to 10.6%) were less clear. CONCLUSIONS: Natural fluctuations in carried meningococcal genotypes and phenotypes a can be affected by the use of conjugate vaccines, and not all of these changes are anticipatable in advance of vaccine introduction

Cost−utility analysis of shockwave lithotripsy vs ureteroscopic stone treatment in adults

Objectives: To assess the cost‐effectiveness, resource use implications, quality‐adjusted life‐years (QALYs) and cost per QALY of care pathways starting with either extracorporeal shockwave lithotripsy (SWL) or with ureteroscopic retrieval (ureteroscopy [URS]) for the management of ureteric stones. Patients and Methods: Data on quality of life and resource use for 613 patients, collected prospectively in the Therapeutic Interventions for Stones of the Ureter (TISU) randomized controlled trial (ISRCTN 92289221), were used to assess the cost‐effectiveness of two care pathways, SWL and URS. A health provider (UK National Health Service) perspective was adopted to estimate the costs of the interventions and subsequent resource use. Quality‐of‐life data were calculated using a generic instrument, the EuroQol EQ‐5D‐3L. Results are expressed as incremental cost‐effectiveness ratios and cost‐effectiveness acceptability curves. Results: The mean QALY difference (SWL vs URS) was −0.021 (95% confidence interval [CI] −0.033 to −0.010) and the mean cost difference was −£809 (95% CI −£1061 to −£551). The QALY difference translated into approximately 10 more healthy days over the 6‐month period for the patients on the URS care pathway. The probabaility that SWL is cost‐effective is 79% at a society's willingness to pay (WTP) threshold for 1 QALY of £30,000 and 98% at a WTP threshold of £20,000. Conclusion: The SWL pathway results in lower QALYs than URS but costs less. The incremental cost per QALY is £39 118 cost saving per QALY lost, with a 79% probability that SWL would be considered cost‐effective at a WTP threshold for 1 QALY of £30 000 and 98% at a WTP threshold of £20 000. Decision‐makers need to determine if costs saved justify the loss in QALYs
