Background: Urinary tract infections (UTIs) are a common and significant problem for patients, clinicians, and healthcare services. Recurrent UTIs (rUTIs) are common, with a 3% prevalence in the UK. Although acute UTIs have a significant negative impact on the lives of patients, evidence of the impact of rUTIs is limited. To enhance shared decision-making around rUTI management, it is important to understand both the patients’ and healthcare professionals’ (HCPs’) perspectives. The objective of this qualitative evidence synthesis is to understand patients’ and HCPs’ experiences and views in the management of rUTIs. Methods: A qualitative evidence synthesis (QES) was performed that included primary qualitative studies involving patients with rUTIs or primary care HCPs who manage patients with rUTIs, up to June 2022. The following databases were searched: MEDLINE, Embase, CINAHL, PsycInfo, ASSIA, Web of Science, Cochrane Database of Systematic Reviews, Epistemonikos, Cochrane Central Registry of Controlled Trials, OpenGrey, and the Health Management Information Consortium (HMIC). The QES was prospectively registered on PROSPERO (CRD42022295662). Reciprocal translation was conducted and developed into a line of argument synthesis. We appraised the confidence in our review findings by using GRADE-CERQual. Results: Twelve studies were included in the final review; ten of those included patients, and three included HCPs (one study included both). Our review demonstrates that women with rUTIs have a unique experience, but it is generally of a chronic condition with significant impacts on numerous aspects of their lives. Antibiotics can be “transformative”, but patients have serious concerns about their use and feel non-antibiotic options need further research and discussion. HCPs share similar views about the impacts of rUTIs and concerns about antibiotic use and find the management of rUTIs to be complex and challenging. Based on our GRADE-CERQual assessment of the review findings, we have moderate confidence in those related to patients and low confidence in those related to HCPs. New conceptual models for both patients and HCPs are presented. Conclusions: This review has significant clinical implications. Patients require information on antibiotic alternative acute and preventative treatments for rUTIs, and this is not currently being addressed. There are communication gaps around the impact of rUTIs on patients, their perceived expectation for antibiotics, and the reasons for treatment failure. Further development of current clinical guidance and a patient decision aid would help address these issues.

#### The bottom line A 15 year old boy attends the emergency department with his mother after sustaining a nasal injury while playing rugby. His mother is worried that her son has fractured his nose. The boy says that his nose feels “very blocked” but otherwise he feels well. Examination shows a swollen nose with some associated bruising and the suspicion of bony nasal deviation to the left. Anterior rhinoscopy shows a bilateral cherry red swelling arising from the nasal septum. An immediate referral is made to the ear, nose, and throat department and the patient undergoes an emergency operation to incise and drain a septal haematoma, with no permanent damage to the nasal septum. Nasal trauma is extremely common, with the nasal bones being the third most commonly fractured bone in the human body.1 2 3 In about 90% of nasal fractures the nasal septum is also injured.1 2 3 A potential serious complication of nasal trauma is a nasal septal haematoma. This is the development of a haematoma between the septal cartilage and the overlying mucoperichondrium.3 4 Damage to the septal cartilage can occur within 24 hours, and if untreated it can rapidly lead to irreversible septal …

Background: Despite the considerable morbidity caused by recurrent urinary tract infections (rUTIs), and the wider personal and public health implications from frequent antibiotic use, few studies adequately describe the prevalence and characteristics of women with rUTIs or those who use prophylactic antibiotics.Aim: To describe the prevalence, characteristics, and urine profiles of women with rUTIs with and without prophylactic antibiotic use in Welsh primary care.Design and setting: This was a retrospective cross-sectional study in Welsh general practice using the Secure Anonymised Information Linkage (SAIL) Databank.Method: The characteristics of women aged ≥18 years with rUTIs or using prophylactic antibiotics from 2010 to 2020, and associated urine culture results from 2015 to 2020, are described.Results: In total, 6.0% (n= 92 213/N= 1 547 919) had rUTIs, and 1.7% (n= 26 862/N= 1 547 919) were prescribed prophylactic antibiotics with the rates increasing after 57 years of age. Only 49.0% (n=13 149/N= 26 862) of users of prophylactic antibiotics met the definition of rUTIs before initiation. The study found that 80.8% (n= 44 947/N= 55 652) of women with rUTIs had a urine culture result in the preceding 12 months with high rates of resistance to trimethoprim and amoxicillin. Of women taking prophylactic antibiotics, 64.2% (n= 9926/N= 15 455) had a urine culture result before initiation and 18.5% (n= 320/N= 1730) of women prescribed trimethoprim had resistance to it on the antecedent sample.Conclusion: A substantial proportion of women had rUTIs or incident prophylactic antibiotic use. However, 64.2% (n= 9926/N= 15 455) of women had urine cultured before starting prophylaxis. There was a high proportion of cultured bacteria resistant to two antibiotics used for rUTI prevention and evidence of resistance to the prescribed antibiotic. More frequent urine cultures for rUTI diagnosis and before prophylactic antibiotic initiation could better inform antibiotic choices.

Introduction: Current UKHSA UTI diagnostic guidance advises empirical antibiotics if two of the following symptoms are present: cloudy urine, dysuria, and new onset nocturia. Hormonal changes during menopause may impact UTI symptoms, and qualitative studies suggest women with recurrent UTIs may present with different UTI symptoms. This study aims to assess whether menopausal status and the presence of recurrent UTIs impact UTI symptoms in women. Methods: An e-survey was conducted between 13 March 2021 and 13 April 2021. Women aged 16 years or older with a history of a UTI in the last year were eligible for inclusion. We defined menopause as those aged 45–64 years; pre-menopause as those less than 45 years; and post-menopause as those 65 years and older. Recurrent UTIs were defined as three or more UTIs in the last year. The data were weighted to be representative of the UK population. Crude unadjusted and adjusted odds ratios were estimated using logistic regression. Results: In total, 1096 women reported a UTI in the last year. There were significant differences in UTI symptoms based on menopausal status and the presence of recurrent UTIs. Post-menopausal women self-reported more incontinence (OR 2.76, 95% CI 1.50,5.09), whereas menopausal women reported more nocturia. Women with recurrent UTIs reported less dysuria, more severe symptoms (OR 1.93 95% CI 1.37,2.73) and a greater impact on daily life (OR 1.68, 95% CI 1.19,2.37). Conclusions: This survey provides evidence that acute UTIs present differently based on menopausal status and in women with recurrent UTIs. It is important that healthcare professionals are aware of these differences when assessing women presenting with an acute UTI and, therefore, further research in this area is needed.

Background: Post-operative delirium is an important, yet under-researched complication of surgery. Patients undergoing urological surgery may be at especially high risk of POD, as they are often older, and interventions can be associated with conditions that trigger delirium. The main aim of this systematic review was to evaluate the available evidence for risk factors in this patient group.Methods: Five databases were searched (MEDLINE, Web of Science, EMBASE, CINAHL and PsychInfo) between January 1987 and June 2019. The Newcastle–Ottawa Scale was used to assess for risk of bias. Pooled odds ratio or mean difference (MD) for individual risk factors were estimated using the Mantel–Haenzel and inverse variance methods.Results: Seven articles met the inclusion criteria, giving a total population of 1937. The incidence of POD ranged from 5 to 29%. Three studies were deemed low risk of bias and four at a high risk of bias. Nine risk factors were suitable for meta-analysis, with age (MD 4.314 95% CI 1.597, 7.032 p = 0.002) and the clock drawing test (MD − 2.443 95% CI − 3.029, − 1.857 p < 0.001) having a statistically significant association with POD in pooled analyses.Conclusion: Delirium is common in urological patients. This review has identified a lack of studies in this surgical population, with wide heterogeneity and high risk of bias. It also highlights a number of potential risk factors for post-operative delirium, of which some are modifiable. However, the strength of evidence is weak at present and so future research should focus on assessing comparable risk factors in this patient group in order to inform future clinical practice.Review registrationThe review protocol was prospectively registered with the PROSPERO database (reference CRD42017054613)
