BackgroundClinical decision rules (CDRs) are commonly used to guide imaging decisions in cervical spine injury (CSI) assessment despite limited evidence for their use in paediatric populations. We set out to determine CSI incidence, imaging rates and the frequency of previously identified CSI risk factors, and thus assess the projected impact on imaging rates if CDRs were strictly applied as a rule in our population.MethodsA single-centre prospective observational study on all aged under 16 years presenting for assessment of possible CSI to a tertiary paediatric emergency department over a year, commencing September 2015. CDR variables from the National Emergency X-Radiography Utilization Study (NEXUS) rule, Canadian C-Spine rule (CCR) and proposed Paediatric Emergency Care Applied Research Network (PECARN) rule were collected prospectively and applied post hoc.Results1010 children were enrolled; 973 had not received prior imaging. Of these, 40.7% received cervical spine imaging; 32.4% X-rays, 13.4% CT scan and 3% MRI. All three CDRs identified the five children (0.5%) with CSI who had not received prior imaging. If CDRs were strictly applied as a rule for imaging, projected imaging rates in our setting would be as follows: NEXUS-44% (95% CI 41% to 47.4%), CCR-at least 48.4% (95% CI 45.3% to 51.7%) and PECARN-68% (95% CI 65.1% to 71.1%).ConclusionCSIs were rare (0.5% of our cohort), however, 40% of children received imaging. CDRs have been designed to guide imaging decisions; if strictly applied as a rule for imaging, the CDRs assessed in this study would increase imaging rates. Projected rates differ considerably depending on the CDR applied. These findings highlight the need for a validated paediatric-specific cervical spine imaging CDR.

Purpose This paper aims to describe a service evaluation study of “Balance” – a National Health Service Tier 2 pilot weight management course delivered in a primary care mental health service. The 12 weekly sessions included dietetic, psychological and behavioural elements underpinned by cognitive behavioural theory and “third-wave” approaches, including acceptance and commitment therapy, compassion-focused therapy and mindfulness. Design/methodology/approach A mixed-methods design was used in this service evaluation study that included analysis of outcome measures (weight, eating choices, weight-related self-efficacy and mental health) and focus group data (n = 6) analysed using thematic analysis. Eleven clients with a body mass index of 25–40 kg/m2 enrolled, and nine clients completed the course. Outcome data were collected weekly with follow-up at three and six months. Findings Quantitative data analysis using non-parametric Wilcoxon signed-rank tests showed that the group mean weight decreased significantly (p = 0.030) by the end of Balance, but the group mean weight loss was not statistically significant at the three-month (p = 0.345) or six-month (p = 0.086) follow-up. The qualitative results showed that participants valued the course ethos of choice and also welcomed learning new tools and techniques. Balance was very well-received by participants who reported benefitting from improved well-being, group support and developing new weight management skills. Research limitations/implications Only one client attended all sessions of the group, and it is possible that missed sessions impacted effectiveness. Some of the weight change data collected at the six-month follow-up was self-reported (n = 4), which could reduce data reliability. Focus group participants were aware that Balance was a pilot with a risk that the group would not be continued. As the group wanted the pilot to be extended, the feedback may have been positively skewed. A small sample size limits interpretation of the results. A group weight management intervention, including dietetic, psychological and behavioural elements, underpinned by cognitive behavioural theory was well-received by service users and effective for some. Commissioners and service users may have different definitions of successful outcomes in weight management interventions. Practical implications Longer-term support and follow-up after Tier 2 weight management interventions may benefit service users and improve outcomes. Originality/value The paper contributes to a small but growing evidence base concerned with the design and delivery of weight management interventions. Areas of particular interest include: a gap analysis between the course content and National Institute for Health and Care Excellence clinical guidelines, participants’ views on the most impactful course features and recommendations for course development. The results also show a disconnect between evidence-based guidelines (mandatory weight monitoring), participants’ preferences and clinicians' experience. The difference between client and commissioner priorities is also discussed.
