Risk Factors for 1-Year Mortality and Hospital Utilization Patterns in Critical Care Survivors: A Retrospective, Observational, Population-Based Data Linkage Study.

Abstract: OBJECTIVES: Clear understanding of the long-term consequences of critical care survivorship is essential. We investigated the care process and individual factors associated with long-term mortality among ICU survivors and explored hospital use in this group. DESIGN: Population-based data linkage study using the Secure Anonymised Information Linkage databank. SETTING: All ICUs between 2006 and 2013 in Wales, United Kingdom. PATIENTS: We identified 40,631 patients discharged alive from Welsh adult ICUs. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Primary outcome was 365-day survival. The secondary outcomes were 30- and 90-day survival and hospital utilization in the 365 days following ICU discharge. Kaplan-Meier curves were plotted to compare survival rates. Cox proportional hazards regression models were used to determine risk factors of mortality. Seven-thousand eight-hundred eighty-three patients (19.4%) died during the 1-year follow-up period. In the multivariable Cox regression analysis, advanced age and comorbidities were significant determinants of long-term mortality. Expedited discharge due to ICU bed shortage was associated with higher risk. The rate of hospitalization in the year prior to the critical care admission was 28 hospitalized days/1,000 d; post critical care was 88 hospitalized days/1,000 d for those who were still alive; and 57 hospitalized days/1,000 d and 412 hospitalized days/1,000 d for those who died by the end of the study, respectively. CONCLUSIONS: One in five ICU survivors die within 1 year, with advanced age and comorbidity being significant predictors of outcome, leading to high resource use. Care process factors indicating high system stress were associated with increased risk. More detailed understanding is needed on the effects of the potentially modifiable factors to optimize service delivery and improve long-term outcomes of the critically ill.

Reliability of frailty assessment in the critically ill: a multicentre prospective observational study

Abstract: Demand for critical care among older patients is increasing in many countries. Assessment of frailty may inform discussions and decision making, but acute illness and reliance on proxies for history-taking pose particular challenges in patients who are critically ill. Our aim was to investigate the inter-rater reliability of the Clinical Frailty Scale for assessing frailty in patients admitted to critical care. We conducted a prospective, multi-centre study comparing assessments of frailty by staff from medical, nursing and physiotherapy backgrounds. Each assessment was made independently by two assessors after review of clinical notes and interview with an individual who maintained close contact with the patient. Frailty was defined as a Clinical Frailty Scale rating > 4. We made 202 assessments in 101 patients (median (IQR [range]) age 69 (65-75 [60-80]) years, median (IQR [range]) Acute Physiology and Chronic Health Evaluation II score 19 (15-23 [7-33])). Fifty-two (51%) of the included patients were able to participate in the interview; 35 patients (35%) were considered frail. Linear weighted kappa was 0.74 (95%CI 0.67-0.80) indicating a good level of agreement between assessors. However, frailty rating differed by at least one category in 47 (47%) cases. Factors independently associated with higher frailty ratings were: female sex; higher Acute Physiology and Chronic Health Evaluation II score; higher category of pre-hospital dependence; and the assessor having a medical background. We identified a good level of agreement in frailty assessment using the Clinical Frailty Scale, supporting its use in clinical care, but identified factors independently associated with higher ratings which could indicate personal bias.

Improving outcome of sepsis on the ward: introducing the ‘Sepsis Six’ bundle

Abstract: Background The Sepsis Six bundle is designed to facilitate early intervention with three diagnostic and three therapeutic steps to be delivered within 1 h to patients with suspected sepsis. Aims and objectives To investigate the effects of delivering the ‘Sepsis Six’ bundle by the Critical Care Outreach team on patient outcomes. Design In a prospective observational study, all adult patients on the general wards from June 2012 to January 2014 with sepsis who were screened and treated by the Critical Care Outreach team were included. Methods The main outcome measure was the change in National Early Warning Score following the delivery of the Sepsis Six bundle within 24 h. Secondary outcomes were 90‐day mortality and overall bundle compliance. Results A total of 207 patients were included in the analysis. Overall bundle compliance was 84%. National Early Warning Scores decreased significantly 24 h after administering the Sepsis Six, from 7·4 ± 2·6 to 3·1 ± 2·4 (p < 0·001). The distribution of the National Early Warning Score changed significantly. Mortality was lower at 90 days when patients who presented with signs of sepsis within 48 h of hospital admission were compared with those who presented with signs of sepsis after 48 h of hospital admission (14·5% versus 35·4% p < 0·03) despite similar baseline physiological variables. Conclusions We found better outcomes after the administration of Sepsis Six. Reliable delivery of the bundle, defined as 80% of patients receiving the standard of care, is achievable, and our quality improvement data suggest that it is likely to be sustainable in our environment. Relevance to clinical practice Sepsis Six can reduce physiological impairment, monitored by the National Early Warning Scores. Consistent delivery of the bundle can lead to better patient outcomes.

Prospective Observational Cohort Study On Grading the Severity of Postoperative Complications in Global Surgery Research

Abstract: BACKGROUND: The Clavien-Dindo classification is perhaps the most widely used approach for reporting postoperative complications in clinical trials. This system classifies complication severity by the treatment provided. However, it is unclear whether the Clavien-Dindo system can be used internationally in studies across differing healthcare systems in high- (HICs) and low- and middle-income countries (LMICs). METHODS: This was a secondary analysis of the International Surgical Outcomes Study (ISOS), a prospective observational cohort study of elective surgery in adults. Data collection occurred over a 7-day period. Severity of complications was graded using Clavien-Dindo and the simpler ISOS grading (mild, moderate or severe, based on guided investigator judgement). Severity grading was compared using the intraclass correlation coefficient (ICC). Data are presented as frequencies and ICC values (with 95 per cent c.i.). The analysis was stratified by income status of the country, comparing HICs with LMICs. RESULTS: A total of 44 814 patients were recruited from 474 hospitals in 27 countries (19 HICs and 8 LMICs). Some 7508 patients (16·8 per cent) experienced at least one postoperative complication, equivalent to 11 664 complications in total. Using the ISOS classification, 5504 of 11 664 complications (47·2 per cent) were graded as mild, 4244 (36·4 per cent) as moderate and 1916 (16·4 per cent) as severe. Using Clavien-Dindo, 6781 of 11 664 complications (58·1 per cent) were graded as I or II, 1740 (14·9 per cent) as III, 2408 (20·6 per cent) as IV and 735 (6·3 per cent) as V. Agreement between classification systems was poor overall (ICC 0·41, 95 per cent c.i. 0·20 to 0·55), and in LMICs (ICC 0·23, 0·05 to 0·38) and HICs (ICC 0·46, 0·25 to 0·59). CONCLUSION: Caution is recommended when using a treatment approach to grade complications in global surgery studies, as this may introduce bias unintentionally.

Real World Patterns of Antimicrobial Use and Microbiology Investigations in Patients with Sepsis outside the Critical Care Unit: Secondary Analysis of Three Nation-Wide Point Prevalence Studies.

Abstract: Recent description of the microbiology of sepsis on the wards or information on the real-life antibiotic choices used in sepsis is lacking. There is growing concern of the indiscriminate use of antibiotics and omission of microbiological investigations in the management of septic patients. We performed a secondary analysis of three annual 24-h point-prevalence studies on the general wards across all Welsh acute hospitals in years 2016–2018. Data were collected on patient demographics, as well as radiological, laboratory and microbiological data within 48-h of the study. We screened 19,453 patients over the three 24 h study periods and recruited 1252 patients who fulfilled the entry criteria. 775 (64.9%) patients were treated with intravenous antibiotics. Only in 33.65% (421/1252) of all recruited patients did healthcare providers obtain blood cultures; in 25.64% (321/1252) urine cultures; in 8.63% (108/1252) sputum cultures; in 6.79% (85/1252) wound cultures; in 15.25% (191/1252) other cultures. Out of the recruited patients, 59.1% (740/1252) fulfilled SEPSIS-3 criteria. Patients with SEPSIS-3 criteria were significantly more likely to receive antibiotics than the non-septic cohort (p < 0.0001). In a multivariable regression analysis increase in SOFA score, increased number of SIRS criteria and the use of the official sepsis screening tool were associated with antibiotic administration, however obtaining microbiology cultures was not. Our study shows that antibiotics prescription practice is not accompanied by microbiological investigations. A significant proportion of sepsis patients are still at risk of not receiving appropriate antibiotics treatment and microbiological investigations; this may be improved by a more thorough implementation of sepsis screening tools.

A Snapshot of Compliance with the Sepsis Six Care Bundle in Two Acute Hospitals in the West Midlands, UK.

Abstract: Background The sepsis six care bundle has been adopted by hospitals in England and Wales for the management of patients with sepsis, with the aim of increasing survival when all elements of the bundle are achieved. Aim To assess compliance with the Sepsis Six Care Bundle in two acute NHS hospitals in the West Midlands. Materials and methods Adults admitted to hospital over a 24-hour period were screened for sepsis. Sepsis was identified using the Systemic Inflammatory Response (SIRS) criteria and the quick sequential organ failure assessment (qSOFA) score. Adherence to the Sepsis Six Care Bundle was assessed. Results 249 patients were screened and 24 patients were identified as having sepsis (9.6%). One patient received all six elements of the bundle. Compliance was highest for giving intravenous fluids (58.3%) and antibiotics (58.3%), and lowest for measuring urine output (16.7%). Conclusions Further research is needed to establish the reasons for low compliance. How to cite this article Frankling C, Patel J, Sharif B, Melody T, Yeung J, Gao F, et al.

Introducing a new sedation policy in a large district general hospital: before and after cohort analysis.

Abstract: Background: The management of pain, agitation and sedation for ventilated patients who are admitted to intensive care is an essential part of their care. The introduction of sedation protocols is associated with improved patient outcomes. Methods: We conducted an observational cohort study among mechanically ventilated patients in a 16-bed ICU over a two-year period. We retrospectively examined data from two patient populations, namely those before and after the introduction of a new sedation protocol in July 2015. The primary outcome was the duration of mechanical ventilation in both groups. Results: After the implementation of the new sedation protocol, there was a significant decrease in the mean duration of mechanical ventilation (1.45 days). Furthermore, we observed a non-significant reduction in the mean duration of ICU stay. Conclusion : The new protocol was associated with outcome improvements including: decreased mean duration of mechanical ventilation and a reduced number of ventilated days; and increased patient throughput with a slight increase in the length of vasopressor support. Moreover, the use of a structure-process-outcome model of quality improvement was associated with significant improvements in process measures of quality.
