Impact of organisation and specialist service delivery on lung cancer outcomes.
No full textINTRODUCTION
Data from the National Lung Cancer Audit (NLCA) often show variation in outcomes between lung cancer units which are not entirely explained by case mix. We explore the association between the organisation of services and patient outcome.
METHODS
Details of service provision were collected via an electronic survey in June 2017. An overall organisational score derived from eleven key service factors from national lung cancer commissioning guidance was calculated for each organisation. The results for each hospital were linked to their patient outcome results from the 2015 NLCA cases. Multivariate logistic regression analysis was used to link the organisational score to patient outcomes.
RESULTS
Lung cancer unit organisational audit scores varied from 0 to 11. Thirty-eight (29%) units had a score of 0-4, 64 (50%) had a score of 5-7 and 27 (21%) had a score of 8-11. Multivariate regression analysis revealed that, compared with an organisational score of 0-4, patients seen at units with a score of 8-11 had higher 1-year survival (adjusted OR (95% CI)=2.30 (1.04 to 5.08), p<0.001), higher curative-intent treatment rate (adjusted OR (95% CI)=1.62 (1.26 to 2.09), p<0.001) and greater likelihood of receiving treatment within 62 days (adjusted OR (95% CI)=1.49 (1.20 to 1.86), p<0.001).
CONCLUSION
National variation in the provision of services and workforce remain. We provide evidence that adherence to the national lung commissioning guidance has the potential to improve patient outcomes within the current service structure

No full textMycobacterium tuberculosis transmission in an ethnically-diverse high incidence region in England, 2007-11.
No full textBACKGROUND
Transmission patterns in high tuberculosis incidence areas in England are poorly understood but need elucidating to focus contact tracing. We study transmission within and between age, ethnic and immigrant groups using molecular data from the high incidence West Midlands region.
METHODS
Isolates from culture-confirmed tuberculosis cases during 2007-2011 were typed using 24-locus Mycobacterial Interspersed Repetitive Unit-Variable Number Tandem Repeats (MIRU-VNTR). We estimated the proportion of disease attributable to recent transmission, calculated the proportion of isolates matching those from the two preceding years ("retrospectively clustered"), and identified risk factors for retrospective clustering using multivariate analyses. We calculated the ratio (RCR) between the observed and expected proportion clustered retrospectively within or between age, ethnic and immigrant groups.
RESULTS
Of the 2159 available genotypes (79% of culture-confirmed cases), 34% were attributed to recent transmission. The percentage retrospectively clustered decreased from 50 to 24% for 0-14 and ≥ 65 year olds respectively (p = 0.01) and was significantly lower for immigrants than the UK-born. Higher than expected clustering occurred within 15-24 year olds (RCR: 1.4 (95% CI: 1.1-1.8)), several ethnic groups, and between UK-born or long-term immigrants with the UK-born (RCR: 1.8 (95% CI: 1.1-2.4) and 1.6 (95% CI: 1.2-1.9) respectively).
CONCLUSIONS
This study is the first to consider "who clusters with whom" in a high incidence area in England, laying the foundation for future whole-genome sequencing work. The higher than expected clustering seen here suggests that preferential mixing between some age, ethnic and immigrant groups occurs; prioritising contact tracing to groups with which cases are most likely to cluster retrospectively could improve TB control
Medication adherence and treatment-resistant hypertension: a review.
No full textNonadherence is a common reason for treatment failure and treatment resistance. No matter how it is defined, it is a major issue in the management of chronic illnesses. There are numerous methods to assess adherence, each with its own strengths and weaknesses; however, no single method is considered the best. Nonadherence is common in patients with hypertension, and it is present in a large proportion of patients with uncontrolled blood pressure taking three or more antihypertensive agents. Availability of procedure-based treatment options for these patients has shed further light on this important issue with development of new methods to assess adherence. There is, however, no consensus on the management of nonadherence, which reflects the complex interplay of factors responsible for it
Clinical presentations of Hepatitis E: A clinical review with representative case histories.
No full textHepatitis E virus (HEV) typically causes an acute, self-limiting hepatitis and is among the commonest cause of such presentations. Hepatitis E viral infection is also increasingly recognized as a cause of chronic hepatitis amongst the immunocompromised, particularly amongst solid organ transplant recipients. Chronic HEV infection remains an underdiagnosed disease and chronic infection can lead to rapidly progressive liver fibrosis and cirrhosis. This review examines current understanding of the HEV. We illustrate typical clinical presentations, management strategies [(based upon guidelines from both the British Transplant Society (BTS) and European Association for the study of liver (EASL)] and outcomes of HEV infection in different cohorts of patients by highlighting select transplant and non-transplant patient cases, from one of the largest tertiary Hepatology centres in Europe
Hypoglycaemia is associated with increased risk of fractures in patients with type 2 diabetes mellitus: a cohort study.
No full textObjective Type 2 diabetes is associated with an increased risk of fracture. Any factor that incrementally increases this risk should be taken into account when individualising treatment. Hypoglycaemia is a common complication of antidiabetes medications and suggested as a risk factor for fractures; yet, its real-life clinical impact is unclear. Design A population-based, retrospective open cohort study using routinely collected data between 1st of January 1995 and 1st of May 2016 in The Health Improvement Network (THIN) database. Methods Patients with type 2 diabetes mellitus with documented hypoglycaemic events were compared to randomly matched patients with type 2 diabetes mellitus without documented hypoglycaemic events matched to exposed patients on age, sex, duration of diabetes and BMI. The primary outcome was any incident fracture. Secondary outcome was incident fragility (osteoporotic) fracture. Results A total of 41 163 patients with type 2 diabetes were included: 14 147 patients in the exposed cohort and 27 016 patients in the unexposed cohort. Patients with a documented hypoglycaemic event were significantly more likely to sustain any fracture compared to patients with no record of hypoglycaemic events: adjusted IRR = 1.20 (95% CI: 1.12-1.30; P < 0.0001). Patients who had a documented hypoglycaemic event were significantly more likely to suffer a fragility fracture compared to controls: adjusted IRR = 1.24 (95% CI: 1.13-1.37; P < 0.0001). Conclusions Hypoglycaemic events are a significant risk factor for fractures in patients with diabetes mellitus. This observation is clinically relevant when individualising targets for glycaemic control and selecting antidiabetic agents

No full textThe respiratory intensive care Assembly of the European Respiratory Society is proud to present a summary of several important sessions held at the International Congress in Paris in 2018. For the highly esteemed reader who may have missed the Congress, a concise review was written on three topics: the state-of-the-art session on respiratory critical care, hot topics in weaning and the best abstracts in noninvasive ventilation
Guidelines for the safe practice of total intravenous anaesthesia (TIVA): Joint Guidelines from the Association of Anaesthetists and the Society for Intravenous Anaesthesia.
No full textGuidelines are presented for safe practice in the use of intravenous drug infusions for general anaesthesia. When maintenance of general anaesthesia is by intravenous infusion, this is referred to as total intravenous anaesthesia. Although total intravenous anaesthesia has advantages for some patients, the commonest technique used for maintenance of anaesthesia in the UK and Ireland remains the administration of an inhaled volatile anaesthetic. However, the use of an inhalational technique is sometimes not possible, and in some situations, inhalational anaesthesia is contraindicated. Therefore, all anaesthetists should be able to deliver total intravenous anaesthesia competently and safely. For the purposes of simplicity, these guidelines will use the term total intravenous anaesthesia but also encompass techniques involving a combination of intravenous infusion and inhalational anaesthesia. This document is intended as a guideline for safe practice when total intravenous anaesthesia is being used, and not as a review of the pros and cons of total intravenous anaesthesia vs. inhalational anaesthesia in situations where both techniques are possible
Cancer as a risk factor for urinary tract calculi: a retrospective cohort study using 'The Health Improvement Network' : Cancer and urinary tract calculi.
No full textPURPOSE
Urolithiasis is a common condition that poses significant morbidity to patients. There are similarities in the development of certain cancers and urinary tract calculi (UTC), however, little is known about their temporal relationship. This study aims to identify if cancer is a risk factor for the development of UTC.
METHODS
A population-based retrospective cohort study was conducted for the period 1st January 1990 to 1st May 2016. 124,901 exposed patients identified using clinical codes with newly diagnosed cancer were matched to 476,203 unexposed controls by age, gender, BMI, and general practice. The main outcome measure was the risk of developing UTC described by hazard ratios.
RESULTS
There were 512 incident UTC events in the cancer group compared to 1787 in the unexposed controls. This translated to an adjusted hazard ratio of 1.26 (95% CI 1.14-1.39; p < 0.001). A sub-analysis assessing cancer-specific effects demonstrated increased risks for 10 out of 12 common cancers, most significantly in bladder, colorectal and prostate cancer.
CONCLUSION
This study demonstrated a 26% increased risk of UTC in cancer patients suggesting wider recognition of this risk amongst clinicians could improve diagnosis and prevention of UTC, as well as encourage further research exploring this association
The addition of insulin to home parenteral nutrition for the control of hyperglycaemia: A case series.
No full textThere is little data on the safety or efficacy of insulin added to parenteral nutrition in the homecare setting. We report the use of this route of insulin administration in a series of 4 patients spanning 39 patient years in which it appeared effective, safe and well tolerated
