RESUMO

BACKGROUND AND AIMS: Despite published guidelines, telemetry use is inappropriate in 25-43% of cases. This impacts patient safety and telemetry effectiveness. QI methodology was used to review telemetry in a hospital acute medical unit with the aim of reducing inappropriate use and addressing alarm fatigue. METHODS: A 'Telemetry Indication Form' was created. Eight weeks of baseline data was collated before introducing the 'Indication Form'. Four plan-do-study-act cycles were conducted. At each cycle, data was analysed using statistical process control charts. RESULTS: Inappropriate telemetry use significantly reduced from 32% to 4%. Total telemetry use also fell. Unfortunately, interventions to address alarm rates did not result in significant reduction in false alarms. CONCLUSIONS: A 'Telemetry Indication Form' has significant potential to improve patient safety through reducing inappropriate use.

RESUMO

The pathogenesis of metabolic-associated fatty liver disease (MAFLD) is complex and thought to be dependent on multiple parallel hits on a background of genetic susceptibility. The evidence suggests that MAFLD progression is a dynamic two-way process relating to repetitive bouts of metabolic stress and inflammation interspersed with endogenous anti-inflammatory reparative responses. In MAFLD, excessive hepatic lipid accumulation causes the production of lipotoxins that induce mitochondrial dysfunction, endoplasmic reticular stress, and over production of reactive oxygen species (ROS). Models of MAFLD show marked disruption of mitochondrial function and reduced oxidative capacitance with impact on cellular processes including mitophagy, oxidative phosphorylation, and mitochondrial biogenesis. In excess, ROS modify insulin and innate immune signaling and alter the expression and activity of essential enzymes involved in lipid homeostasis. ROS can also cause direct damage to intracellular structures causing hepatocyte injury and death. In select cases, the use of anti-oxidants and ROS scavengers have been shown to diminish the pro-apoptopic effects of fatty acids. Given this link, endogenous anti-oxidant pathways have been a target of interest, with Nrf2 activation showing a reduction in oxidative stress and inflammation in models of MAFLD. Thyroid hormone receptor ß (THRß) agonists and nuclear peroxisome proliferation-activated receptor (PPAR) family have also gained interest in reducing hepatic lipotoxicity and restoring hepatic function in models of MAFLD. Unfortunately, the true interplay between the clinical and molecular components of MAFLD progression remain only partly understood. Most recently, multiomics-based strategies are being adopted for hypothesis-free analysis of the molecular changes in MAFLD. Transcriptome profiling maps the unique genotype-phenotype associations in MAFLD and with various single-cell transcriptome-based projects underway, there is hope of novel physiological insights to MAFLD progression and uncover therapeutic targets.

RESUMO

OBJECTIVE: Chronic liver disease continues to be a significant cause of morbidity and mortality yet remains challenging to prognosticate. This has been one of the barriers to implementing palliative care, particularly at an early stage. The Bristol Prognostic Score (BPS) was developed to identify patients with life expectancy less than 12 months and to act as a trigger for referral to palliative care services. This study retrospectively evaluated the BPS in a cohort of patients admitted to three Scottish hospitals. METHOD: Routinely collated healthcare data were used to obtain demographics, BPS and analyse 1-year mortality for patients with decompensated liver disease admitted to three gastroenterology units over two 90-day periods. Statistical analysis was undertaken to assess performance of BPS in predicting mortality. RESULTS: 276 patients were included in the final analysis. Participants tended to be late middle-aged men, socioeconomically deprived and have alcohol-related liver disease. A similar proportion was BPS+ve (>3) in this study compared with the original Bristol cohort though had more hospital admissions, higher ongoing alcohol use and poorer performance status. BPS performed poorer in this non-Bristol group with sensitivity 54.9% (72.2% in original study), specificity 58% (83.8%) and positive predictive value (PPV) 43.4% (81.3%). CONCLUSION: BPS was unable to accurately predict mortality in this Scottish cohort. This highlights the ongoing challenge of prognostication in patients with chronic liver disease, furthering the call for more work in this field.

RESUMO

Starting in a new hospital can be an overwhelming experience for any grade of doctor. There is a vast amount of information that needs to be learnt immediately to function in the new environment. There is an annual changeover of doctors between hospitals in August nationwide and most junior doctors rotate specialties every 4-6 months. Evidence shows that doctors feel this transition has a negative impact on patient care and indicates that inpatient mortality rises during the August changeover. In our hospital, we noted problems with access to guidelines, referral information and investigations by junior doctors, especially at changeover. In an initial questionnaire, 100% of doctors had experienced difficulties with referring to a specialty and 96% felt time was wasted doing so. Furthermore, 87.5% of doctors had difficulties with ordering laboratory investigations and 100% of survey participates expressed difficulty accessing guidelines.To tackle this issue, we created guidelines on how to refer to different specialties, order investigations and general running of the hospital. We then used a free app platform called induction and uploaded the guidelines as well as formal hospital guidelines to the app. After use of the app, we assessed these problems via further questionnaires. Doctors reporting problems with finding how to refer to specialties reduced from 100% to 0% in the final survey. Problems finding how to request investigations fell from 100% to 14.3% after 1 month to 7.7% after 3 months. Finally, problems finding guidelines fell from 100% to 15.4%. Further, 100% of doctors felt the app saved time.Use of the induction app to access guidelines saves time and reduces problems accessing information needed to carry out tasks. This an easily replicated project with low running costs which proved to help with the universal problems around induction to a new hospital environment.

RESUMO

There has long been a recognised association between non-alcoholic fatty liver disease (NAFLD) and the composite aspects of the metabolic syndrome. Part of this association highlighted the supposed co-existence of elevated uric acid levels in those with NAFLD. There is interest in exploitation of this as a putative diagnostic and prognostic biomarker in NAFLD. Given the increased economic and health burden associated with the NAFLD epidemic, improved methods of population-based, minimally-invasive methods and biomarkers are clearly highly sought and necessary. In this opinion review we review the proposed role of uric acid in the pathogenesis of NAFLD and its potential utilisation in the diagnosis and monitoring of the disease process.

RESUMO

Hepatitis C (HCV) and hepatitis B (HBV), are blood-borne viruses that can cause acute hepatitis; but are clinically relevant because chronic infection is associated with development of cirrhosis and hepatocellular carcinoma. Both these viruses are becoming more common in the older population, due to the ageing of generations exposed to the risk factors associated with infection; intravenous drug use, multiple sexual partners and men who have sex with men. This review will cover the natural history and epidemiology of these infections as well as the revolution in drug therapy that now allows cure of HCV infection and complete control of HBV infection.

RESUMO

PURPOSE OF REVIEW: The pathogenesis of DILI is currently unknown; however, research has shown strong genetic associations with some DILIs. This paper describes the variant alleles uncovered by GWAS and discusses their potential role as susceptibility biomarkers. RECENT FINDINGS: An association with HLADRB1*15:01 and amoxicillin/clavulanate DILI has been shown by a number of research groups. The presence of the HLA-B*57:01 allele has been associated with an 81-fold increased risk of flucloxacillin DILI. The HLA-B*35:02 allele has significant association with minocycline DILI. SUMMARY: With the exception of abacavir for HIV therapy, no other prospective genetic screening tests have met the threshold for clinical application. This is largely because DILI incidence is too low to warrant the cost and effort associated with testing. Perhaps, with the development of personalised medicine, a panel of genes for disease susceptibility, drug efficacy and adverse reactions could be tested once off. This would change the cost-effectiveness paradigm, personalise healthcare and reduce DILI risk by avoiding medications in patients with specific HLA alleles.
