Prevalence of illicit drugs use and association with in-hospital major adverse events in patients hospitalised for acute cardiac events: the ADDICT-ICCU Trial

Background

The prevalence and short-term cardiovascular consequences of illicit drug use in patients admitted to the intensive cardiac care unit (ICCU) for acute cardiovascular events are not well established.

Purpose

The Addiction in Intensive Cardiac Care Units (ADDICT-ICCU) study was designed to assess prospectively the prevalence of illicit drugs use, and their association with the occurrence of in-hospital major adverse events (MAEs) in consecutive patients admitted to ICCUs for acute cardiovascular events.

Methods

From 7 to 22 April 2021, screening for illicit drug was performed by systematic urinary testing in a prospective study including all consecutive patients admitted to ICCU in 39 centres throughout France. The primary outcome was the prevalence of the illicit drugs detected. The secondary clinical outcome was in-hospital Major Adverse cardiac Events (MAEs) defined by death, resuscitated cardiac arrest or cardiogenic shock.

Results

Among 1,499 consecutive patients screened (age 63.3±14.9 years, 69.6% male), 161 (10.7%) had a positive test for illicit drugs (cannabis: 9.1%, opioids: 2.1%, cocaine: 1.7%, amphetamines: 0.7%, 3,4-methylenedioxymethamphetamine: 0.6%). Patients who used illicit drugs were young (33.0% at age <40 vs. 5.9% at age ≥60 years), and more frequently male (11.9% vs. 8.1%, p<0.001). Self-reported current use was 56.5% in patients with a positive test. After a median duration of hospitalisation of five days, there were 61 in-hospital MAEs (4.1%).

The detection of illicit drugs was associated with a higher rate of MAEs after adjustment for known predictors of severity (OR=8.84; 95% CI: 4.68–16.7, p<0.001) or after using a propensity score adjustment (OR=5.81; 95% CI: 4.14–8.14, p<0.001). After adjustment for age and sex, detection of cannabis or cocaine was significantly associated with MAEs (OR=3.53; 95% CI: 1.25–9.95, p<0.001; OR=5.12; 95% CI: 1.48–17.2, p=0.004 respectively). Multiple drug detection (28% of positive patients) was associated with a higher incidence of MAEs than single drug detection.

Conclusions

The prevalence of illicit drugs use in patients hospitalised in the ICCUs for acute cardiovascular events was 10.7% and was under-reported. Illicit drugs detection was independently associated with a higher occurrence of in-hospital MAEs.

[Complementary and alternative medicine use by lung cancer patients]

INTRODUCTION

Complementary and alternative medicine (CMA) use is frequent among cancer patients. Only few results are available about lung cancer patients. The aim of this study was to evaluate how often the CMA were used by lung cancer patients and to define the type of CMA used.

METHODS

Every lung cancer patients with an ongoing chemotherapy in the respiratory department of the University Hospital of Nancy were approached between November 2014 to July 2015. A detailed and anonymous survey was conducted and the socioeconomic characteristics were collected from medical records.

RESULTS

Ninety-one patients were questioned. On 82 patients having answered, 19.5 % had used at least a CMA. The main CMA used was the physical exercise in 50 % of the patients. CMA users were significantly younger with a mean age of 56.4 years versus 65.4 years (P=0.0007). More than half patients did not indicate to their specialist that they used a CMA. The main information source was the circle of acquaintances.

CONCLUSIONS

CMA use is frequent among lung cancer patients. The physical exercise is quoted most of the time among the various CMA. There is a real lack of communication on the subject between the physician and the patient. It is thus imperative that the pulmonologists give much interest to these practices in order to give better advices and to reinforce the patient-physician relationship.
