Physician's first clinical impression of emergency department patients with nonspecific complaints is associated with morbidity and mortality.

The association between the physician's first clinical impression of a patient with nonspecific complaints and morbidity and mortality is unknown. The aim was to evaluate the association of the physician's first clinical impression with acute morbidity and mortality. We conducted a prospective observational study with a 30-day follow-up. This study was performed at the emergency departments (EDs) of 1 secondary and 1 tertiary care hospital, from May 2007 to February 2011. The first clinical impression ("looking ill"), expressed on a numerical rating scale from 0 to 100, age, sex, and the Charlson Comorbidity Index (CCI) were evaluated. The association was determined between these variables and acute morbidity and mortality, together with receiver operating characteristics, and validity. Of 217,699 presentations to the ED, a total of 1278 adult nontrauma patients with nonspecific complaints were enrolled by a study team. No patient was lost to follow-up. A total of 84 (6.6%) patients died during follow-up, and 742 (58.0%) patients were classified as suffering from acute morbidity. The variable "looking ill" was significantly associated with mortality and morbidity (per 10 point increase, odds ratio 1.23, 95% confidence interval [CI] 1.12-1.34, P < 0.001, and odds ratio 1.19, 95% CI 1.14-1.24, P < 0.001, respectively). The combination of the variables "looking ill," "age," "male sex," and "CCI" resulted in the best prediction of these outcomes (mortality: area under the curve [AUC] 0.77, 95% CI 0.72-0.82; morbidity: AUC 0.68, 95% CI 0.65-0.71). The physician's first impression, with or without additional variables such as age, male sex, and CCI, was associated with morbidity and mortality. This might help in the decision to perform further diagnostic tests and to hospitalize ED patients.

Nerve compression syndromes in ALS: a retrospective analysis in 554 patients.

We retrospectively screened a large cohort of 554 ALS patients with regard to documented nerve compression syndromes and identified 23 patients, mostly with carpal tunnel syndrome. Patients could be subdivided into three groups. Group A comprised 13 patients in whom nerve compression was apparently confused with early ALS signs. Group B consisted of six patients diagnosed with carpal tunnel syndrome who had experienced improvement after surgery years before they eventually developed ALS. Group C consisted of four patients who, after diagnosis of ALS, additionally developed a nerve compression syndrome. Altogether, the frequency of true nerve compression syndromes in our ALS cohort (1.8%) was no higher than in the general population (0.3-10.8%). In group A, the initial confusion with a nerve compression syndrome led to a slight though not significant delay (15.2 vs. 12.9 months; p = 0.32) of the diagnosis of ALS. Survival was no different between group A and the cohort. It can also be concluded that the misdiagnoses could have been avoided by thorough electrophysiological examination using a standardized protocol.
