Prevalence of sodium-glucose transporter 2 inhibitor-associated diabetic ketoacidosis in real-world data: A systematic review and meta-analysis.

BACKGROUND: The U.S. Food and Drug Administration (FDA) revised the labels of sodium-glucose transporter 2 (SGLT2) inhibitors in December 2015 to inform users regarding the risk of diabetic ketoacidosis (DKA). As more drugs of this class are approved and their indications are expanded, this serious adverse effect has been increasingly reported. OBJECTIVE: This review evaluated observational studies to inform the prevalence of SGLT2-inhibitor-associated DKA compared with other antihyperglycemic agents. METHODS: A systematic review was conducted in PubMed and EMBASE until 19 July 2022 (PROSPERO: CRD42022385425). We included published retrospective cohort active comparator/new user (ACNU) and prevalent new user studies assessing SGLT2-inhibitor-associated DKA prevalence in adult patients with type 2 diabetes mellitus (T2DM) against active comparators. We excluded studies which lacked 1:1 propensity score matching. The JBI Checklist for Cohort Studies guided the risk-of-bias assessments. Meta-analysis was conducted based on the inverse variance method in R software. RESULTS: Sixteen studies with a sample of 2,956,100 nonunique patients met the inclusion criteria. Most studies were conducted in North America (n = 9) and adopted the ACNU design (n = 15). Meta-analysis of 14 studies identified 33% higher DKA risk associated with SGLT2 inhibitors (HR = 1.33, 95% CI: 1.14-1.55, P < 0.01). Meta-regression analysis identified the study location (P = 0.02), analysis principle (P < 0.001), exclusion of chronic comorbidities (P = 0.007), and canagliflozin (P = 0.04) as significant moderator variables. CONCLUSIONS: Despite limitations related to heterogeneity, generalizability, and misclassification, the results of this study show that SGLT2 inhibitors increase the prevalence of DKA among adult T2DM patients in the real world. The findings supplement evidence from randomized controlled trials (RCTs) and call for continued vigilance.

CRISPR-Cas9 system: a novel and promising era of genotherapy for beta-hemoglobinopathies, hematological malignancy, and hemophilia.

Gene therapy represents a significant potential to revolutionize the field of hematology with applications in correcting genetic mutations, generating cell lines and animal models, and improving the feasibility and efficacy of cancer immunotherapy. Compared to different genetic engineering tools, clustered regularly interspaced short palindromic repeats (CRISPR) CRISPR-associated protein 9 (Cas9) emerged as an effective and versatile genetic editor with the ability to precisely modify the genome. The applications of genetic engineering in various hematological disorders have shown encouraging results. Monogenic hematological disorders can conceivably be corrected with single gene modification. Through the use of CRISPR-CAS9, restoration of functional red blood cells and hemostasis factors were successfully attained in sickle cell anemia, beta-thalassemia, and hemophilia disorders. Our understanding of hemato-oncology has been advanced via CRIPSR-CAS9 technology. CRISPR-CAS9 aided to build a platform of mutated genes responsible for cell survival and proliferation in leukemia. Therapeutic application of CRISPR-CAS9 when combined with chimeric antigen receptor (CAR) T cell therapy in multiple myeloma and acute lymphoblastic leukemia was feasible with attenuation of CAR T cell therapy pitfalls. Our review outlines the latest literature on the utilization of CRISPR-Cas9 in the treatment of beta-hemoglobinopathies and hemophilia disorders. We present the strategies that were employed and the findings of preclinical and clinical trials. Also, the review will discuss gene engineering in the field of hemato-oncology as a proper tool to facilitate and overcome the drawbacks of chimeric antigen receptor T cell therapy (CAR-T).

Attitude towards deprescribing and its association with frailty and complexity of medication regimen: A survey of older inpatients in a district health board in New Zealand.

BACKGROUND: Older inpatients, particularly those with frailty, have increased exposure to complex medication regimens. It is not known whether frailty and complexity of medication regimens influence attitudes toward deprescribing. This study aimed to investigate (1) older inpatients' attitudes toward deprescribing; (2) if frailty and complexity of medication regimen influence attitudes and willingness to deprescribe - a relationship that has not been investigated in previous studies. METHODS: In this cross-sectional study, older adults (≥ 65 years) recruited from general medicine and geriatric services in a New Zealand hospital completed the revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire. Hospital frailty risk score (HFRS) was calculated using diagnostic codes and other relevant information present at the time of index hospital admission; higher scores indicate higher frailty risk. Medication regimen complexity was quantified using the medication regimen complexity index (MRCI); higher scores indicate greater complexity. Logistic regression analysis was used to identify predictors of attitudes and willingness to deprescribe. RESULTS: A total of 222 patients were included in the study, the median age was 83 years and 63% were female. One in two patients reported feeling they were taking too many medications, and 1 in 5 considered their medications burdensome. Almost 3 in 4 (73%) wanted to be involved in decision-making about their medications, and 4 in 5 (84%) were willing to stop one or more of their medications if their prescriber said it was possible. Patients with higher MRCI had increased self-reported medication burden (adjusted odds ratio (AOR) 2.6, 95% CI 1.29, 5.29) and were more interested in being involved in decision-making about their medications (AOR 1.8, CI 0.99, 3.42) than those with lower MRCI. Patients with moderate HFRS had lower odds of willingness to deprescribe (AOR 0.45, CI 0.22,0.92) compared to the low-risk group. Female patients had a lower desire to be involved in decision-making. The oldest old age group( > 80 years) had lower self-reported medication burden and were less likely to want to try stopping their medications. CONCLUSION: Most older inpatients wanted to be involved in decision-making about their medications and were willing to stop one or more medications if proposed by their prescriber. Medication complexity and frailty status influence patients' attitudes toward deprescribing and thus should be taken into consideration when making deprescribing decisions. Further research is needed to investigate the relationship between frailty and the complexity of medication regimens.

Estimating productivity levels in primary medical services across clinical commissioning groups in England and the impact of the COVID-19 pandemic: a data envelopment analysis.

OBJECTIVES: To assess the relative productivity of primary medical services in England and the impact of the COVID-19 pandemic on productivity levels. SETTING: Primary medical services for 59 million patients (98% of the population in England), in 101 clinical commissioning groups (CCGs), across two time periods: period 1, pre-pandemic, April to December 2019 and period 2, pandemic, April to December 2020. METHODS: We use data envelopment analysis (DEA) to assess relative productivity with four input measures (the number of full-time equivalent general practitioners, nurses, other direct patient contact staff and administrators), and five output measures (face-to-face appointments, remote consultations, home visits, referrals to secondary care and prescriptions). Our units of analysis were CCGs. DEA assigns an efficiency score to a CCG, taking a value between 0 and 100%, by benchmarking it against the most productive CCGs. We use Tobit regression to examine the association between productivity and other factors. RESULTS: The mean bias-corrected efficiency score of primary medical services in CCGs was 92.9% (interquartile range 92.0% to 95.7%) in period 1, falling to 90.6% (interquartile range 86.8% to 95.2%) in period 2. In period 1, CCGs with a higher proportion of registered patients aged over 65 years, higher levels of deprivation, lower levels of disease prevalence, higher nurse to GP ratios and higher GP to other direct patient contact staff ratios, achieved statistically significantly higher general practice efficiency scores (p < 0.05). In period 2, only the ratio of GP to other direct patient contact staff was associated with efficiency scores (p > 0.05). CONCLUSIONS: Our analysis indicates only modest geographic variation in productivity of primary medical services when measured at the level of clinical commissioning groups and a small reduction in productivity during the pandemic. Further work to establish relative productivity of individual GP practices is warranted once sufficient data on appointment rates by GP practice is available.

The Effect of Ramadan Intermittent Fasting on Food Intake, Anthropometric Indices, and Metabolic Markers among Premenopausal and Postmenopausal Women: A Cross-Sectional Study.

Background and objectives: Ramadan intermittent fasting (RIF) is a monthlong practice in which Muslims fast during the whole day from sunrise to sunset. During this month, fasting people change their dietary behavior and alter their eating hours from day to night. The objective of the current study was to examine the effect of RIF on dietary consumption, anthropometric indices, and metabolic markers in healthy premenopausal (PRE-M) and postmenopausal (POST-M) Saudi women. Materials and Methods: The study included 62 women (31 PRE-M, 21-42 years, and 31 POST-M, 43-68 years). A structured questionnaire was used to collect socioeconomic data. Physical activity, anthropometric, dietary, and biochemical assessments were assessed before and at the end of the third week of Ramadan. Results: Socioeconomic data varied among participants. For both groups, observing RIF was associated with significantly (at either p ≤ 0.01 or p ≤ 0.05) lower intake of calories, macronutrients, minerals (excluding Na), and vitamins than before RIF. For the PRE-M group, the percentage of overweight participants decreased significantly (p ≤ 0.01) during Ramadan, while the percentage of obese participants remained unchanged. In contrast, for the POST-M group, the percentage of overweight participants increased significantly (p ≤ 0.05) during Ramadan, but dropped at the end of Ramadan. Following RIF, waist-to-hip ratio, body fat, and fat mass (FM) decreased in both groups. High-density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), triglycerides (TG), and blood pressure (SBP, DBP) were generally maintained at acceptable normal levels in most participants before and at the end of RIF. However, low-density lipoprotein cholesterol (LDL-C) at the end of RIF was significantly lower than before, particularly in POST-M women. Age, occupation, and monthly income were the most important predictors for the changes in nutritional status and body fat upon RIF. Conclusions: observing RIF by PRE-M and POST-M Saudi women was associated with significant improvements in variable health indicators, with a few exceptions, and may help lower risk factors for chronic diseases, particularly among POST-M women. However, further studies with a larger sample size are required to determine and confirm the exact effect of RIF on these groups.

Efficacy and safety of remdesivir in hospitalised COVID-19 patients: a systematic review and meta-analysis.

PURPOSE: This review was aimed to synthesise the best available evidence on the effectiveness and safety of remdesivir in the treatment of moderate to severe COVID-19. METHOD: Randomised controlled trials (RCTs) and observational studies reporting the effectiveness and safety of remdesivir were searched via databases and other sources from December 2019 to December 2020. Two independent reviewers performed literature screening, data extraction and assessment of risk bias. Seven studies involving 3686 patients were included. RESULTS: Treatment with remdesivir was associated with an increase in clinical recovery rate by 21% (RR 1.21; 95% CI 1.08-1.35) on day 7 and 29% (RR 1.29; 95% CI 1.22-1.37) on day 14. The likelihoods of requiring high-flow supplemental oxygen and invasive mechanical ventilation in the remdesivir group were lower than in the placebo group by 27% (RR 0.73; 95% CI 0.54-0.99) and 47% (RR 0.53; 95% CI 0.39-0.72), respectively. Remdesivir-treated patients showed a 39% (RR 0.61; 95% CI 0.46-0.79) reduction in the risk of mortality on day 14 compared to the control group; however, there was no significant difference on day 28. Serious adverse effects (SAEs) were significantly less common in patients treated with remdesivir, with an absolute risk difference of 6% (RD -0.06; 95% CI -0.09 to -0.03). CONCLUSION: Despite conditional recommendation against its use, remdesivir could still be effective in early clinical improvement; reduction of early mortality and avoiding high-flow supplemental oxygen and invasive mechanical ventilation among hospitalised COVID-19 patients. Remdesivir was also well tolerated without significant SAEs compared to placebo, yet available evidence from clinical studies support the need to conduct close monitoring.

Relationship between emergency department and inpatient occupancy and the likelihood of an emergency admission: a retrospective hospital database study.

BACKGROUND: We investigate whether admission from a consultant-led ED is associated with ED occupancy or crowding and inpatient (bed) occupancy. METHODS: We used general additive logistic regression to explore the relationship between the probability of an ED patient being admitted, ED crowding and inpatient occupancy levels. We adjust for patient, temporal and attendance characteristics using data from 13 English NHS Hospital Trusts in 2019. We define quintiles of occupancy in ED and for four types of inpatients: emergency, overnight elective, day case and maternity. RESULTS: Compared with periods of average occupancy in ED, a patient attending during a period of very high (upper quintile) occupancy was 3.3% less likely (relative risk (RR) 0.967, 95% CI 0.958 to 0.977) to be admitted, whereas a patient arriving at a time of low ED occupancy was 3.9% more likely (RR 1.039 95% CI 1.028 to 1.050) to be admitted. When the number of overnight elective, day-case and maternity inpatients reaches the upper quintile then the probability of admission from ED rises by 1.1% (RR 1.011 95% CI 1.001 to 1.021), 3.8% (RR 1.038 95% CI 1.025 to 1.051) and 1.0% (RR 1.010 95% CI 1.001 to 1.020), respectively. Compared with periods of average emergency inpatient occupancy, a patient attending during a period of very high emergency inpatient occupancy was 1.0% less likely (RR 0.990 95% CI 0.980 to 0.999) to be admitted and a patient arriving at a time of very low emergency inpatient occupancy was 0.8% less likely (RR 0.992 95% CI 0.958 to 0.977) to be admitted. CONCLUSIONS: Admission thresholds are modestly associated with ED and inpatient occupancy when these reach extreme levels. Admission thresholds are higher when the number of emergency inpatients is particularly high. This may indicate that riskier discharge decisions are taken when beds are full. Admission thresholds are also high when pressures within the hospital are particularly low, suggesting the potential to safely reduce avoidable admissions.

Evaluation of nutritional status of foreign students at King Saud University, Kingdom of Saudi Arabia.

OBJECTIVE: The current study was conducted to assess the nutritional status and associated risk factors among foreign students residing at King Saud University for different periods and to explore its correlations. DESIGN: A cross-sectional study was conducted during the spring semester of 2018. A total of 400 male students aged 18-35 years had participated in the current study after signing a written consent form according to Helsinki Declaration. SETTING: A structural questionnaire was used to collect data on daily food intake and habits and socio-economic characteristics. Nutrients of food intake were assessed using the Esha programme and compared with that of dietary requirement intake (DRI). A body composition analyser was used to measure body fat (BF), visceral fat (VF) and BMI. Spearman correlation coefficients and simple regression analysis were performed to determine associations between variables. PARTICIPANTS: Foreign students residing for different periods (<6 months: 200 students and >6 months: 200 students) were used as subjects. RESULTS: The students who stayed <6 months consumed lower level of some nutrients than that of the DRI compared with those stayed >6 months. Overweight and obesity were more common among students who stayed >6 months with high values of BF and VF. Several risk factors were positively or negatively correlated with the students' nutrition proxies. CONCLUSION: Most of the students who stayed >6 months are suffered from overweight. Some independent variables were found to be significantly correlated with the students' nutrition proxies either positively or negatively.

Fidelity and the impact of patient safety huddles on teamwork and safety culture: an evaluation of the Huddle Up for Safer Healthcare (HUSH) project.

BACKGROUND: The Patient Safety Huddle (PSH) is a brief multidisciplinary daily meeting held to discuss threats to patient safety and actions to mitigate risk. Despite growing interest and application of huddles as a mechanism for improving safety, evidence of their impact remains limited. There is also variation in how huddles are conceived and implemented with insufficient focus on their fidelity (the extent to which delivered as planned) and potential ways in which they might influence outcomes. The Huddle Up for Safer Healthcare (HUSH) project attempted to scale up the implementation of patient safety huddles (PSHs) in five hospitals - 92 wards - across three UK NHS Trusts. This paper aims to assess their fidelity, time to embed, and impact on teamwork and safety culture. METHODS: A multi-method Developmental Evaluation was conducted. The Stages of Implementation Checklist (SIC) was used to determine time taken to embed PSHs. Observations were used to check embedded status and fidelity of PSH. A Teamwork and Safety Climate survey (TSC) was administered at two time-points: pre- and post-embedding. Changes in TSC scores were calculated for Trusts, job role and clinical speciality. RESULTS: Observations confirmed PSHs were embedded in 64 wards. Mean fidelity score was 4.9/9. PSHs frequently demonstrated a 'fear free' space while Statistical Process Control charts and historical harms were routinely omitted. Analysis showed a positive change for the majority (26/27) of TSC questions and the overall safety grade of the ward. CONCLUSIONS: PSHs are feasible and effective for improving teamwork and safety culture, especially for nurses. PSH fidelity criteria may need adjusting to include factors deemed most useful by frontline staff. Future work should examine inter-disciplinary and role-based differences in TSC outcomes.

Serum Albumin Level as a Predictor of Outcome in Patients Admitted to Pediatric Intensive Care Units.

OBJECTIVE: The aim of this study was to assess serum albumin level on admission to the pediatric intensive care unit (PICU) as a prognostic indicator. METHODS: A prospective study was conducted in Fayoum University Children's Hospital. The study subjects' demographics and clinical and laboratory data were recorded. Pediatric Risk of Mortality III (PRISM-III) score was calculated. Serum albumin level was assessed within 24 hours from admission. Outcomes included mortality, PICU and hospital stay, need and duration of mechanical ventilation, and inotrope use. RESULTS: The incidence of admission hypoalbuminemia was 26%. The study subjects had a significantly higher mortality rate than subjects with normal albumin levels (42.3% vs 17.6%, respectively, P = 0.011). Each unit of increase in serum albumin decreased the risk of mortality by 28.9% (odds ratio, 0.289; confidence interval, 0.136-0.615, P = 0.001). Serum albumin showed a fair discriminatory power (area under the curve, 0.738). At a cutoff point of ≤3.7 g/dL, albumin had a 79.2% sensitivity, 67.1% specificity, 43.2% positive predictive value, and 91.1% negative predictive value. Incorporation of serum albumin with PRISM-III score was more predictive of mortality than either predictors alone (area under the curve, 0.802). No significant difference was found between the 2 groups regarding either PICU and hospital stay as well as the need and duration of ventilation. CONCLUSIONS: In PICUs, admission hypoalbuminemia is a good predictor of mortality. Further studies to confirm the value of adding serum albumin to PRISM-III score are recommended.

Inhibition of Lipid Accumulation and Adipokine Levels in Maturing Adipocytes by Bauhinia rufescens (Lam.) Stem Bark Extract Loaded Titanium Oxide Nanoparticles.

The present study reports a cost-effective, environmentally friendly method to increase the bioavailability and bio-efficacy of B. rufescens stem bark extract in the biological system via functional modification as B. rufescens stem bark nanoparticles (BR-TO2-NPs). The biosynthesis of BR- -NPs was confirmed by UV-visible (UV-vis) and Fourier-transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM), and X-ray diffraction analyses. The shifts in FT-IR stretching vibrations of carboxylic and nitro groups (1615 cm-1), the O-H of phenolics or carboxylic acids (3405 cm-1), alkanes, and alkyne groups (2925 and 2224 cm-1) of the plant extract and lattice (455) indicated successful biosynthesis of BR- -NPs. Compared with the stem bark extract, 40 ng/dL dose of BR- -NPs led to a reduction in adipogenesis and an increase in mitochondrial biogenesis-related gene expressions, adiponectin-R1, PPARγC1α, UCP-1, and PRDM16, in maturing-adipocytes. This confirmed the intracellular uptake, bioavailability, and bio-efficiency of BR-TiO2-NPs. The lipid-lowering capacity of BR-TiO2-NPs effectively inhibited the metabolic inflammation-related gene markers, IL-6, TNF-α, LTB4-R, and Nf-κb. Further, BR-TiO2-NPs stimulating mitochondrial thermogenesis capacity was proven by the significantly enhanced CREB-1 and AMPK protein levels in adipocytes. In conclusion, BR-TiO2-NPs effectively inhibited lipid accumulation and proinflammatory adipokine levels in maturing adipocytes; it may help to overcome obesity-associated comorbidities.

An Organizational-Level Program of Intervention for AKI: A Pragmatic Stepped Wedge Cluster Randomized Trial.

BACKGROUND: Variable standards of care may contribute to poor outcomes associated with AKI. We evaluated whether a multifaceted intervention (AKI e-alerts, an AKI care bundle, and an education program) would improve delivery of care and patient outcomes at an organizational level. METHODS: A multicenter, pragmatic, stepped-wedge cluster randomized trial was performed in five UK hospitals, involving patients with AKI aged ≥18 years. The intervention was introduced sequentially across fixed three-month periods according to a randomly determined schedule until all hospitals were exposed. The primary outcome was 30-day mortality, with pre-specified secondary endpoints and a nested evaluation of care process delivery. The nature of the intervention precluded blinding, but data collection and analysis were independent of project delivery teams. RESULTS: We studied 24,059 AKI episodes, finding an overall 30-day mortality of 24.5%, with no difference between control and intervention periods. Hospital length of stay was reduced with the intervention (decreases of 0.7, 1.1, and 1.3 days at the 0.5, 0.6, and 0.7 quantiles, respectively). AKI incidence increased and was mirrored by an increase in the proportion of patients with a coded diagnosis of AKI. Our assessment of process measures in 1048 patients showed improvements in several metrics including AKI recognition, medication optimization, and fluid assessment. CONCLUSIONS: A complex, hospital-wide intervention to reduce harm associated with AKI did not reduce 30-day AKI mortality but did result in reductions in hospital length of stay, accompanied by improvements in in quality of care. An increase in AKI incidence likely reflected improved recognition.

Computer-aided National Early Warning Score to predict the risk of sepsis following emergency medical admission to hospital: a model development and external validation study.

BACKGROUND: In hospitals in England, patients' vital signs are monitored and summarized into the National Early Warning Score (NEWS); this score is more accurate than the Quick Sepsis-related Organ Failure Assessment (qSOFA) score at identifying patients with sepsis. We investigated the extent to which the accuracy of the NEWS is enhanced by developing and comparing 3 computer-aided NEWS (cNEWS) models (M0 = NEWS alone, M1 = M0 + age + sex, M2 = M1 + subcomponents of NEWS + diastolic blood pressure) to predict the risk of sepsis. METHODS: We included all emergency medical admissions of patients 16 years of age and older discharged over 24 months from 2 acute care hospital centres (York Hospital [YH] for model development and a combined data set from 2 hospitals [Diana, Princess of Wales Hospital and Scunthorpe General Hospital] in the Northern Lincolnshire and Goole National Health Service Foundation Trust [NH] for external model validation). We used a validated Canadian method for defining sepsis from administrative hospital data. RESULTS: The prevalence of sepsis was lower in YH (4.5%, 1596/35 807) than in NH (8.5%, 2983/35 161). The C statistic increased across models (YH: M0 0.705, M1 0.763, M2 0.777; NH: M0 0.708, M1 0.777, M2 0.791). For NEWS of 5 or higher, sensitivity increased (YH: 47.24% v. 50.56% v. 52.69%; NH: 37.91% v. 43.35% v. 48.07%), the positive likelihood ratio increased (YH: 2.77 v. 2.99 v. 3.06; NH: 3.18 v. 3.32 v. 3.45) and the positive predictive value increased (YH: 11.44% v. 12.24% v. 12.49%; NH: 22.75% v. 23.55% v. 24.21%). INTERPRETATION: From the 3 cNEWS models, model M2 is the most accurate. Given that it places no additional burden of data collection on clinicians and can be automated, it may now be carefully introduced and evaluated in hospitals with sufficient informatics infrastructure.

"Change is what can actually make the tough times better": A patient-centred patient safety intervention delivered in collaboration with hospital volunteers.

BACKGROUND: The PRASE (Patient Reporting and Action for a Safe Environment) intervention provides a way to systematically collect patient feedback to support service improvement. To provide a sustainable mechanism for the PRASE intervention, a 2-year improvement project explored the potential for hospital volunteers to facilitate the collection of PRASE feedback. OBJECTIVE: To explore the implementation of the PRASE intervention delivered in collaboration with hospital volunteers from the perspectives of key stakeholders. DESIGN: A qualitative case study design was utilized across three acute NHS trusts in the United Kingdom between March 2016 and October 2016. Ward level data (staff interviews; action planning meeting recordings; implementation fidelity information) were analysed taking a pen portrait approach. We also carried out focus groups with hospital volunteers and interviews with voluntary services/patient experience staff, which were analysed thematically. RESULTS: Whilst most ward staff reported feeling engaged with the intervention, there were discordant views on its use and usefulness. The hospital volunteers were positive about their involvement, and on some wards, worked with staff to produce actions to improve services. The voluntary services/patient experience staff participants emphasised the need for PRASE to sit within an organisations' wider governance structure. CONCLUSION: From the perspective of key stakeholders, hospital volunteers facilitating the collection of PRASE feedback is a feasible means of implementing the PRASE intervention. However, the variability around ward staff being able to use the feedback to make changes to services demonstrates that it is this latter part of the PRASE intervention cycle that is more problematic.

Sustaining the commitment to patient safety huddles: insights from eight acute hospital ward teams.

BACKGROUND: A recent initiative in hospital settings is the patient safety huddle (PSH): a brief multidisciplinary meeting held to highlight patient safety issues and actions to mitigate identified risks. AIM: The authors studied eight ward teams that had sustained PSHs for over 2 years in order to identify key contributory factors. METHODS: Unannounced observations of the PSH on eight acute wards in one UK hospital were undertaken. Interviews and focus groups were also conducted. These were recorded and transcribed for framework analysis. FINDINGS: A range of factors contributes to the sustainability of the PSH including a high degree of belief and consensus in purpose, adaptability, determination, multidisciplinary team involvement, a non-judgemental space, committed leadership and consistent reward and celebration. CONCLUSION: The huddles studied have developed and been shaped over time through a process of trial and error, and persistence. Overall this study offers insights into the factors that contribute to this sustainability.

Development and External Validation of an Automated Computer-Aided Risk Score for Predicting Sepsis in Emergency Medical Admissions Using the Patient's First Electronically Recorded Vital Signs and Blood Test Results.

OBJECTIVES: To develop a logistic regression model to predict the risk of sepsis following emergency medical admission using the patient's first, routinely collected, electronically recorded vital signs and blood test results and to validate this novel computer-aided risk of sepsis model, using data from another hospital. DESIGN: Cross-sectional model development and external validation study reporting the C-statistic based on a validated optimized algorithm to identify sepsis and severe sepsis (including septic shock) from administrative hospital databases using International Classification of Diseases, 10th Edition, codes. SETTING: Two acute hospitals (York Hospital - development data; Northern Lincolnshire and Goole Hospital - external validation data). PATIENTS: Adult emergency medical admissions discharged over a 24-month period with vital signs and blood test results recorded at admission. INTERVENTIONS: None. MAIN RESULTS: The prevalence of sepsis and severe sepsis was lower in York Hospital (18.5% = 4,861/2,6247; 5.3% = 1,387/2,6247) than Northern Lincolnshire and Goole Hospital (25.1% = 7,773/30,996; 9.2% = 2,864/30,996). The mortality for sepsis (York Hospital: 14.5% = 704/4,861; Northern Lincolnshire and Goole Hospital: 11.6% = 899/7,773) was lower than the mortality for severe sepsis (York Hospital: 29.0% = 402/1,387; Northern Lincolnshire and Goole Hospital: 21.4% = 612/2,864). The C-statistic for computer-aided risk of sepsis in York Hospital (all sepsis 0.78; sepsis: 0.73; severe sepsis: 0.80) was similar in an external hospital setting (Northern Lincolnshire and Goole Hospital: all sepsis 0.79; sepsis: 0.70; severe sepsis: 0.81). A cutoff value of 0.2 gives reasonable performance. CONCLUSIONS: We have developed a novel, externally validated computer-aided risk of sepsis, with reasonably good performance for estimating the risk of sepsis for emergency medical admissions using the patient's first, electronically recorded, vital signs and blood tests results. Since computer-aided risk of sepsis places no additional data collection burden on clinicians and is automated, it may now be carefully introduced and evaluated in hospitals with sufficient informatics infrastructure.

Albumin-Bilirubin Score: An Accurate Predictor of Hepatic Decompensation in High-Risk Patients Undergoing Transarterial Chemoembolization for Hepatocellular Carcinoma.

PURPOSE: To evaluate validity of albumin-bilirubin (ALBI) grade as a predictor of acute-on-chronic liver failure (ACLF) after transarterial chemoembolization for hepatocellular carcinoma (HCC) in patients with baseline moderate to severe liver dysfunction. MATERIALS AND METHODS: In this retrospective study, serum albumin and bilirubin levels measured before chemoembolization were used to calculate ALBI score in 123 patients treated with 187 high-risk chemoembolizations. Procedures were considered high risk if Child-Turcotte-Pugh score before chemoembolization was ≥ 8. ACLF was objectively measured using chronic liver failure-sequential organ failure assessment score at 30 and 90 d. The 30-day mortality and morbidity from new or worsening ascites and/or hepatic encephalopathy (HE) were assessed. Univariate and multivariate analyses were used to identify clinical and procedural predictors of ACLF in this high-risk population. RESULTS: ACLF occurred after 15 (8%) high-risk chemoembolizations within 30 days and an additional 9 (5%) procedures between 30 and 90 days. Overall 30-day mortality was 2.7%. New or worsened ascites and/or HE occurred after 52 (28%) procedures within 30 days. Significant prognosticators of ACLF at 90 days revealed by univariate analysis were bilirubin (P = .004), albumin (P = .007), and ALBI score (P = .002), with ALBI score remaining statistically significant on multivariate regression analysis (OR = 3.99; 95% CI, 1.70-9.40; P = .002). CONCLUSIONS: Chemoembolization for HCC can be performed safely in patients with moderate to severe liver dysfunction. ALBI score before chemoembolization provides objective prognostication for ACLF after chemoembolization in this cohort and may be used for risk stratification.

Measurement of blood pressure for the diagnosis and management of hypertension in different ethnic groups: one size fits all.

BACKGROUND: Hypertension is a major risk factor for cardiovascular disease and prevalence varies by ethnic group. The diagnosis and management of blood pressure are informed by guidelines largely based on data from white populations. This study addressed whether accuracy of blood pressure measurement in terms of diagnosis of hypertension varies by ethnicity by comparing two measurement modalities (clinic blood pressure and home monitoring) with a reference standard of ambulatory BP monitoring in three ethnic groups. METHODS: Cross-sectional population study (June 2010 - December 2012) with patients (40-75 years) of white British, South Asian and African Caribbean background with and without a previous diagnosis of hypertension recruited from 28 primary care practices. The study compared the test performance of clinic BP (using various protocols) and home-monitoring (1 week) with a reference standard of mean daytime ambulatory measurements using a threshold of 140/90 mmHg for clinic and 135/85 mmHg for out of office measurement. RESULTS: A total of 551 participants had complete data of whom 246 were white British, 147 South Asian and 158 African Caribbean. No consistent difference in accuracy of methods of blood pressure measurement was observed between ethnic groups with or without a prior diagnosis of hypertension: for people without hypertension, clinic measurement using three different methodologies had high specificity (75-97%) but variable sensitivity (33-65%) whereas home monitoring had sensitivity of 68-88% and specificity of 64-80%. For people with hypertension, detection of a raised blood pressure using clinic measurements had sensitivities of 34-69% with specificity of 73-92% and home monitoring had sensitivity (81-88%) and specificity (55-65%). CONCLUSIONS: For people without hypertension, ABPM remains the choice for diagnosing hypertension compared to the other modes of BP measurement regardless of ethnicity. Differences in accuracy of home monitoring and clinic monitoring (higher sensitivity of the former; higher specificity of the latter) were also not affected by ethnicity.

Maternal health inequalities and GP provision: investigating variation in consultation rates for women in the Born in Bradford cohort.

Background: The 'Five Year Forward View' (NHS England) calls for a radical upgrade in public health provision. Inequalities in maternal health may perpetuate general patterns of health inequalities across generations; therefore equitable access to general practice (GP) provision during maternity is important. This paper explores variation in GP consultation rates for disadvantaged mothers. Method: Data from the Born in Bradford cohort (around 12 000 women), combined with GP records and GP practice variables, were modelled to predict GP consultation rates, before and after adjusting for individual health and GP provision. Results: Observed GP consultation rates are higher for women in materially deprived neighbourhoods and Pakistani women. However these groups were found to consult less often after controlling for individual health. This difference, around one appointment per year, is 'explained' by the nature of GP provision. Women in practices with a low GP to patient ratio had around 09 fewer consultations over the six year period compared to women in practices with the highest ratio. Conclusions: Equitable access to GP services, particularly for women during the maternal period, is essential for tackling deep-rooted health inequalities. Future GP funding should take account of neighbourhood material deprivation to focus resources on areas of the greatest need.

A qualitative formative evaluation of a patient-centred patient safety intervention delivered in collaboration with hospital volunteers.

BACKGROUND: Evidence suggests that patients can meaningfully feed back to healthcare providers about the safety of their care. The PRASE (Patient Reporting and Action for a Safe Environment) intervention provides a way to systematically collect feedback from patients to support service improvement. The intervention is being implemented in acute care settings with patient feedback collected by hospital volunteers for the first time. OBJECTIVE: To undertake a formative evaluation which explores the feasibility and acceptability of the PRASE intervention delivered in collaboration with hospital volunteers from the perspectives of key stakeholders. DESIGN: A qualitative evaluation design was adopted across two acute NHS trusts in the UK between July 2014 and November 2015. We conducted five focus groups with hospital volunteers (n=15), voluntary services and patient experience staff (n=3) and semi-structured interviews with ward staff (n=5). Data were interpreted using framework analysis. RESULTS: All stakeholders were positive about the PRASE intervention as a way to support service improvement, and the benefits of involving volunteers. Volunteers felt adequate training and support would be essential for retention. Staff concentrated on the infrastructure needed for implementation and raised concerns around sustainability. Findings were fed back to the implementation team to support revisions to the intervention moving into the subsequent summative evaluation phase. CONCLUSION: Although there are concerns regarding sustainability in practice, the PRASE intervention delivered in collaboration with hospital volunteers is a promising approach to collect patient feedback for service improvement.
