Validity of self-reports of drinking before injury by cause of injury and societal context among emergency department patients

Clinician assessment of blood alcohol levels among emergency department patients

INTRODUCTION

Alcohol intoxication is a significant public health concern and is commonly seen among emergency department (ED) patients. This study was undertaken to identify the accuracy of clinician assessment of blood alcohol levels among emergency department patients.

METHODS

This prospective survey study was conducted at a Level 1 Trauma Center. Eligible study participants included physicians, nurses, and medical students involved in the care of patients who had BAC. Clinicians estimated the BAC prior to results availability.

RESULTS

Among 243 clinicians, the mean difference between the estimated BAC and actual BAC was 17.4 (95% CI: 4.7 to 30.1). Providers tended to overestimate the actual BAC level. The accuracy between roles (attendings, residents, RNs, students) was not significant (ANOVA p-value 0.90). Accuracy was not correlated with age of the patient (Pearson correlation 0.04, p-value 0.54). Accuracy was not associated with the patient's gender (Student's t-test two-tailed p-value 0.90), ethnicity (White versus all others, t-test p-value 0.31), nor insurance (government versus not government, t-test p-value 0.81). The average accuracy value was associated with mode of arrival (t-test p-value 0.003). The average accuracy for walk-in subjects was -14.9 (CI: -32.8 to 3.1) compared to ambulance arrivals 28.3 (CI: 12.7 to 44.0). Providers underestimated BAC for walk-ins and overestimated BAC for ambulance arrivals. Among 107 patients with a BAC of 0, clinician estimates ranged from 0 to 350. Clinicians estimated non-zero BAC levels in 17% of patients with BAC of 0 (N = 18).

CONCLUSIONS

Clinicians' estimates of BAC were often inaccurate, and often overestimated the BAC.

Prevalence of alcohol consumption in emergency presentations: Novel approach using two biomarkers, ethanol and phosphatidylethanol

INTRODUCTION

The aim was to determine the prevalence of alcohol-related presentations to an emergency department (ED) in a major Australian hospital, through a novel surveillance approach using two biomarkers, blood ethanol and phosphatidylethanol (PEth).

METHODS

Observational study using secondary testing of blood samples collected during routine clinical care of ED patients presenting to the Royal Brisbane and Women's Hospital in Queensland, Australia, between 22 January and 2 February 2021. Data were collected from 1160 patients during the 10-day study period. The main outcomes were the prevalence of acute alcohol intake, as determined by blood ethanol, and recent use over 2-4 weeks, as determined by PEth concentrations, for all ED presentations and different diagnostic groups.

RESULTS

The overall prevalence for blood ethanol was 9.3% (95% confidence interval [CI] 7.8%, 11.1%), 5.3% for general medical presentations, increasing four-fold to 22.2% for injury presentations. The overall prevalence of PEth positive samples was 32.5% (95% CI 29.9%, 35.3%) and 41.4% for injury presentations. There were 263 (25.3%) cases that tested negative for acute blood ethanol but positive for PEth concentrations indicative of significant to heavy medium-term alcohol consumption.

DISCUSSION AND CONCLUSIONS

This novel surveillance approach demonstrates that using blood ethanol tests in isolation significantly underestimates the prevalence of medium-term alcohol consumption in ED presentations. Prevalence of alcohol use was higher for key diagnostic groups such as injury presentations. Performing periodic measurement of both acute and medium-term alcohol consumption accurately and objectively in ED presentations, would be valuable for informing targeted public health prevention and control strategies.

Concerned others' help utilization and patients' alcohol treatment outcomes

BACKGROUND

This study of dyads composed of patients in treatment for alcohol use disorders (AUDs) and their Concerned Others (COs) examined (1) COs' attendance at three types of help (educational sessions, treatment sessions with the patient, and treatment sessions without the patient) during a 3-month period after patients' admission, and (2) whether COs' use of help was associated with better treatment outcomes reported by COs about patients, and patients about themselves.

METHODS

Dyads (n = 277) were assessed when patients entered AUD treatment and 3 months later (80 %). COs rated their patient's AUD, and patients rated their own AUD, on the Brief Addiction Monitor. At 3-month follow-up, COs answered three items about help (education, treatment with patient, treatment without patient) from their patient's treatment program. Main analyses were analyses of covariance to examine associations between COs' help use and patients' outcomes.

RESULTS

At 3-month follow-up, COs who had obtained one type of help were significantly more likely to have also obtained the other two types of help. However, relatively few COs (39 %) obtained any type of help. COs who obtained help rated their patient as having more protection against future substance use. And, when COs had obtained help, patients rated themselves as having less risk of future substance use, and had attended a greater number of AA meetings, than when COs had not obtained help.

CONCLUSIONS

Findings suggest that COs' use of help can benefit patients in AUD treatment. Clinicians and researchers should increase the availability and use of help among COs.

Current NAFLD guidelines for risk stratification in diabetic patients have poor diagnostic discrimination

Patients with type 2 diabetes (T2D) are at risk for non-alcoholic fatty liver disease (NAFLD) and associated complications. This study evaluated the performance of international (EASL-EASD-EASO) and national (DGVS) guidelines for NAFLD risk stratification. Patients with T2D prospectively underwent ultrasound, liver stiffness measurement (LSM) and serum-based fibrosis markers. Guideline-based risk classification and referral rates for different screening approaches were compared and the diagnostic properties of simplified algorithms, genetic markers and a new NASH surrogate (FAST score) were evaluated. NAFLD risk was present in 184 of 204 screened patients (age 64.2 ± 10.7 years; BMI 32.6 ± 7.6 kg/m2). EASL-EASD-EASO recommended specialist referral for 60-77% depending on the fibrosis score used, only 6% were classified as low risk. The DGVS algorithm required LSM for 76%; 25% were referred for specialised care. The sensitivities of the diagnostic pathways were 47-96%. A simplified referral strategy revealed a sensitivity/specificity of 46/88% for fibrosis risk. Application of the FAST score reduced the referral rate to 35%. This study (a) underlines the high prevalence of fibrosis risk in T2D, (b) demonstrates very high referral rates for in-depth hepatological work-up, and (c) indicates that simpler referral algorithms may produce comparably good results and could facilitate NAFLD screening.
