ObjectivesWe postulate that performance feedback is a prerequisite to ensure sustained improvement in diabetic ketoacidosis (DKA) management.DesignThe study was based on ‘theory of change’ concept that suggests changes of primary drivers determine the main outcome. A set of secondary drivers can be implemented to achieve improvements in these primary drivers and thus the main outcome.SettingThis study was conducted at a large tertiary care center in the West Midlands, UK. The region has above average prevalence of diabetes and DKA admissions in the country.ParticipantsAll participants diagnosed with DKA as per national guidelines, except those managed in intensive care unit from April 2014 to March 2018, were included in this study.InterventionsMonthly feedback of performance was the main intervention. Development of a real-time live DKA audit tool, automatic referral system of DKA to the specialist team, electronic monitoring of blood gas measurements and education and redesigning of local (trust) guidelines were the other interventions in this study.Main outcome measuresTotal DKA duration, appropriateness of fixed rate intravenous insulin infusion, fluid prescription, glucose monitoring, ketone monitoring and referral to specialists.ResultsThere was a significant reduction in the duration of DKA postintervention compared with baseline results. However, in the absence of regular feedback, the duration of DKA showed an upward trend nearing baseline values. Similar trends were noted in secondary drivers influencing DKA duration.ConclusionBased on these results, we recommend regular audit and feedback is required to sustain improvements in DKA management.

Objective Ophthalmic complications in Systemic Lupus Erythematosus (SLE) are broad and can occur in up to a third of patients. The British Isles Lupus Assessment Group (BILAG) 2004 Index identifies 13 ocular manifestations of active SLE, as opposed to those related to previous disease activity and/or the consequences of therapy. We conducted a systematic review of published literature to determine the frequency of ophthalmic manifestations of active SLE. Methods A systematic literature search of Ovid MEDLINE and EMBASE from their respective inceptions to July 2020 was conducted to identify cohort, case–control and cross-sectional studies. Results 22 studies meeting eligibility criteria were included. Most studies featured small sample sizes and were judged to have a high risk of methodological bias. The number and quality of studies did not allow us to confidently estimate the incidence of the conditions. No studies reported epidemiological data for orbital inflammation/myositis/proptosis. The prevalence of each of the other ocular manifestations, with the exception of retinal vaso-occlusive disease, was consistently less than 5%. Retinal vasculitis, uveitis and isolated cotton wool spots tended to be associated with more active SLE disease. Conclusion The prevalence of eye disease due to SLE activity is uncommon, but clinicians should be aware that some conditions tend to be associated with more active systemic disease. Further studies to determine the incidence and risk factors for these ophthalmic manifestations are needed.
