Clinical decision-making at the end of life: the role of the patient's wish

Information about medical decision-making in the last stage of life and the wishes of terminally ill patients is scarce. At two hospital departments, we observed 16 multidisciplinary meetings and recorded 110 discussions concerning 74 patients. Thirty-three of these discussions concerned either starting or forgoing potentially life-prolonging therapy or applying potentially life-shortening medical interventions. The wishes of the patients were considered in 15 of these discussions. In 6 of these 15 discussions, the patient’s wish was unknown. In five discussions the decision was postponed to enable discussions with the patients. Potentially life-shortening decisions were never made if patients were known to disagree. No decisions about physician-assisted death were made. The study shows that medical end-of-life decisions are commonly shared between the involved caregivers and the patients.     

A Preliminary Study of an Internet‐Based Intervention for OEF/OIF Veterans Presenting for VA Specialty PTSD Care

This preliminary study sought to evaluate the feasibility and potential effectiveness of a cognitive–behavioral, web‐based intervention for posttraumatic stress in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans who are not able to participate, or not eligible to participate, in evidence‐based posttraumatic stress disorder (PTSD) treatments. The study used an uncontrolled pre‐posttest design with a sample of 24 OEF/OIF veterans presenting to a VA PTSD specialty clinic. Participants used the afterdeployment.org, Post‐Traumatic Stress (PTS) Workshop, which was supplemented with brief weekly telephone calls. Half of the participants (n = 12) completed at least 5 of the 8 workshop sessions. At posttreatment, 40.0% of completers demonstrated reliable reductions on PTSD symptoms and overall d = 1.04. Treatment satisfaction and acceptability was generally positive based on Likert ratings. This web‐based intervention for PTS appears to be a feasible and potentially helpful intervention for veterans who may not otherwise receive psychosocial interventions. Given the minimal resources required and the potential reach, this web‐based intervention could be a viable addition to services provided to OEF/OIF veterans seeking PTSD specialty care. Efforts to further develop and more rigorously evaluate this approach are warranted.     

Considerations of healthcare professionals in medical decision-making about treatment for clinical end-stage cancer patients

In order to determine which considerations healthcare professionals use in decision-making about treatment for inpatients with end-stage cancer, we observed 110 discussions at multidisciplinary meetings at two oncology departments. The discussions concerned 74 patients. Thirty-three of the 110 discussions concerned potentially life-prolonging or life-shortening treatments. The most important decision-making considerations were chance of improvement, patient's treatment wishes, amount of suffering, and the chance of therapy being successful. Discussions resulted in 6 decisions that might shorten life, 10 decisions that might prolong life, and 23 postponements of decisions because of lack of information. These observations confirm that medical interventions with a possible life-prolonging or life-shortening effect are a frequently discussed issue in medical decision-making for end-stage cancer patients in The Netherlands. Before making a decision, healthcare professionals gather extensive information about what gain is to be expected from an intervention. When healthcare professionals establish that a decision would be medically appropriate, the patient's wish will often be an important consideration.     

The effect of norepinephrine, isoprenaline and acetylcholine on the testicular and epididymal circulation in the pig

Blood flow to the testis and epididymis of 7 anaesthetized male pigs was measured using electromagnetic blood flow sensors. An average blood flow to the testis of 12 ml/min/100 g and in the epididymal arteries of 19 ml/min/100 g was measured. The effect of intravenously administered norepinephrine, isoprenaline and acetylcholine on α and β₂ adrenergic and cholinergic receptor sites, respectively, was investigated. As neither norepinephrine nor isoprenaline, nor acetylcholine changed vascular conductance of the testis, we could not demonstrate adrenergic and cholinergic receptor activity. The possibility of autonomic regulation by the nonvascular smooth muscles of the spermatic cord and the inner layer of the tunica albuginea has been discussed.     

A Critical Note on Treatment of a Severe Diltiazem Intoxication: High‐Dose Calcium and Glucagon Infusions

The morbidity and mortality of a severe calcium channel blocker intoxication is high due to serious toxic cardiac effects. Its treatment is supported by low‐quality evidence from the heterogeneous literature. We describe a case of a severe diltiazem intoxication and critically appraise the efficacy and role of high‐dose calcium and glucagon infusions. A 53‐year‐old woman was admitted to the emergency department with a cardiogenic shock with complete AV block, not responding to atropine, isoprenaline and an external pacemaker. Later on, it became clear that she had a severe diltiazem intoxication which was successfully treated with isotone fluids, inotropes, vasopressors and continuous infusion of high‐dose calcium and glucagon. The patient developed, however, an acute, necrotizing pancreatitis, probably related to iatrogenic high calcium levels. This case demonstrates lack of consensus regarding target levels of serum calcium for treatment of a severe diltiazem intoxication. Goal‐directed tapering of calcium should prevent side effects of iatrogenic hypercalcaemia. The contribution of glucagon infusions is doubtful due to the instability of solubilized glucagon. This might explain why the effect of glucagon is variable in the literature.     

Prevalence and burden of chronic migraine in adolescents: results of the chronic daily headache in adolescents study (C-dAS)

(Headache 2011;51:693‐706) Objective.— To estimate the prevalence of chronic migraine (CM) among adolescents and to describe the epidemiologic profile, headache characteristics, disability, and healthcare utilization of adolescents with CM in the USA. Background.— Chronic daily headache (CDH) and CM occur in children and adolescents, but are poorly understood in these populations because their presentation is different from that in adults. It may be difficult to assign a definitive diagnosis to young people suffering from CDH because symptoms may fail to meet the criteria for one of the CDH subtypes. Methods.— A large sample of households with at least one resident aged 12 to 19 years was selected in balance with the US Census. Data were collected in 3 phases: (1) mailed questionnaire; (2) telephone interview; and (3) 30‐day interactive voice response system diary. CM prevalence was estimated by adapting the second edition of the International Classification of Headache Disorders criteria for CM to include pediatric migraine diagnostic criteria. The population was stratified for medication overuse. Medication overuse was defined as 15 or more days per month of acute medication use. Included in the study were measures of headache characteristics, headache impact (Headache Impact Test), disability (Pediatric Migraine Disability Assessment), and healthcare and medication use. Data are reported on subjects 12 to 17 years of age only. Results.— The US adolescent (12‐17 years) prevalence rate for CM was 0.79% (0.00‐1.70) excluding those with medication overuse and 1.75% (0.62‐2.89) when adolescents with medication overuse were included. The majority of adolescents with CM had Headache Impact Test scores greater than or equal to 60, indicating severe headache impact, and mean Pediatric Migraine Disability Assessment scores greater than 17, indicating severe headache and disability. The majority of adolescents with CM (approximately 60%) had not visited a healthcare provider in the previous year and less than one in 5 reported taking medications to prevent headaches during the last month. Conclusions.— Results suggest that CM occurs less frequently in adolescents than adults, but like adults, adolescents are severely burdened by the disorder. Data support an unmet medical need; however, the development of optimal criteria for diagnosing adolescents with CM is critical to fully understanding how medical needs can be met within this complex population.
