Prevalence of advance directives and impact on advanced life support in out-of-hospital cardiac arrest victims.

AIM: To evaluate the prevalence of advance directives and their impact on the management of out-of-hospital cardiac arrest (OHCA) victims. METHODS: We analyzed data extracted from the French national registry of adult OHCA patients (RéAC). The data concerned the emergency medical services (EMS) of a Paris suburb over the period 01/01/2013 to 30/11/2015. The primary endpoint was the prevalence of advance directives. Secondary endpoints were the characteristics of the population, of cardiac arrest, and of basic life support as well as outcomes in patients with or without advance directives. RESULTS: Advance directives were available for 148/1985 (7.5%) of OHCA patients. Advanced life support was given to 35 patients with directives and 941 patients without (24% vs. 51%, p <0.0001) with no significant difference in the characteristics of the support provided. Spontaneous recovery of cardiac activity was observed in 5 patients with directives and in 217 patients without (14% vs. 23%, p=0.3). Among patients with advance directives, only one was admitted to hospital. He/she died within 24h of admission. CONCLUSION: Advance directives were accessed by EMS for 7.5% OHCA patients. Despite their availability, advanced life support was provided to 24% of patients.

Prevalence and management of acute pain in prehospital emergency medicine.

BACKGROUND: Less is known about the prevalence of pain in prehospital emergency medicine than about pain in the emergency department. Objectives. To estimate the prehospital prevalence of pain and to identify the factors associated with oligoanalgesia. METHODS: The mobile intensive care units of the emergency services of a Paris suburb conducted this prospective study. All consecutive patients aged 16 years or older who were able to self-assess pain were included around the clock over a period of 11 months in 2007. RESULTS: Among the 2,279 included patients, 947 had acute pain (42% [95% confidence interval (CI) 40-44]). Pain was intense to severe in 64% of patients. Factors associated with acute pain were trauma (odds ratio [OR] = 2.9 [1.9-4.3]) and age under 75 years (OR = 2.2 [1.7-2.8]). Intense pain was significantly associated with pain of cardiac or traumatic origin. Among the 1,364 patients transported by the mobile units, 48% experienced acute pain (71% had intense to severe pain). An analgesic agent was administered to 73%. According to multivariate analysis, only gynecologic/obstetric emergencies were associated with inadequate treatment (OR = 0.2 [95% CI 0.1-0.6]). Overall, 51% of patients [46-56] experienced pain relief. The rate of pain relief was lowest in patients suffering from trauma or a gynecologic/obstetric disorder. CONCLUSION: In our studied population, pain in prehospital emergency medicine affects 42% of patients. However, the rate varies widely according to the origin of the pain. Pain management is inadequate, as only one in two patients experiences relief.
