Patient recall of medication details in the outpatient clinic. Audit and assessment of the value of printed instructions requesting patients to bring medications to clinic.

OBJECTIVE: There is no ambiguity when a patient presents their medications in the correct packaging during a consultation and declares, "this is what I am taking, doctor, I take this many, at this time". The aim of this study was to establish the prevalence of consultations in which patients attend both "empty handed" and unsure of their treatment. A re-evaluation was made after a simple intervention. DESIGN: Prospective cross sectional study with subsequent intervention and re-evaluation based on patient completed questionnaire. SETTING: University hospital cardiology outpatient department. PATIENTS: Consecutive patients arriving at clinic reception desks. RESULTS: Altogether 774 of 857 patients were receiving treatment; 15% attended with their tablets and 28% provided a note of their medication in some form; 40% attended empty handed but confident they could recall all aspects of their treatment from memory; 17% attended empty handed and unsure of their treatment. INTERVENTION: Clinic appointment cards were stamped with the request PLEASE BRING YOUR MEDICATIONS WITH YOU TO THE CARDIOLOGY CLINIC. A second unrelated cohort of patients was then surveyed in an identical manner, nine months later. Of these, 329 of 376 patients were receiving medication. Those attending with their tablets in hand now accounted for 78% rather than 15% (chi(2)=423, df=2, p<0.001). The group unsure of their treatment, but attending empty handed, fell from 17% to 2%. CONCLUSIONS: Reprinted appointment cards are highly successful in encouraging patients to attend with their tablets. This provides reliable information for decision making.

Print media coverage of research on passive smoking.

OBJECTIVE: To assess the extent and content of newspaper and magazine coverage of research on passive smoking. DESIGN: Content analysis of newspaper and magazine articles. SUBJECTS: Articles reporting on passive smoking research published in newspapers (n = 180) or magazines (n = 92) between January 1981 and December 1994. MAIN OUTCOME MEASURES: Numbers of articles, conclusions of articles, sources quoted, numbers and characteristics of research studies cited, presence of tobacco advertising. RESULTS: The number of newspaper and magazine articles reporting on passive smoking research increased from four in 1981 to 57 in 1992 and 32 in 1994. Sixty-two per cent (168/272) of articles concluded that the research on passive smoking is controversial. Tobacco industry representatives were quoted significantly more often in newspaper articles (52%, 94/180) than magazine articles (12%, 11/92) (p<0.0001). Of 121 different research studies cited in the lay press articles, only 15 were from tobacco-industry sponsored projects or publications. In magazines, acceptance of tobacco industry advertising was associated with the conclusion that research on passive smoking is controversial (p<0.0001). CONCLUSIONS: Although research on the harmful effects of passive smoking accumulated between 1981 and 1994, lay press coverage of the research maintained that the science was controversial. Few research studies were cited to support the industry's claim that passive smoking is not harmful to health. However, tobacco industry representatives who were critical of the research methods used to study the health effects of passive smoking were frequently quoted.

Digital chest radiography with a solid-state flat-panel x-ray detector: contrast-detail evaluation with processed images printed on film hard copy.

PURPOSE: To evaluate and compare human observer performance in a contrast-detail test by using postprocessed hard-copy images from a digital chest radiography system and conventional screen-film radiographs. MATERIALS AND METHODS: The digital radiography system is based on a large-area flat-panel x-ray detector with a structured cesium iodide scintillator layer and an amorphous silicon thin-film transistor array for image readout. Images of a contrast-detail phantom were acquired at two exposure levels by using two standard thoracic screen-film systems and the digital system at matched dose. By using images of the phantom processed with standard chest image postprocessing techniques, a four-alternative forced-choice observer perception study was performed, and the number of detectable test signals (disk-shaped objects 0.3-4.0 mm in diameter) was determined for each image type. RESULTS: On average, observers detected more test signals on digital images than on screen-film radiographs at all diameters up to 2.0 mm and an equivalent number at larger diameters. Test signals with lower inherent subject contrast were detected more readily on digital images than on screen-film images, even when x-ray exposure levels for the digital system were reduced by 20%. CONCLUSION: Observer performance in a contrast-detail detection task can be improved by using images acquired with the flat-panel digital chest radiography system as compared with those acquired with state-of-the-art screen-film combinations.

[Tobacco advertising and printed mass media in Spain: a fatal attraction].

OBJECTIVE: Tobacco advertising is a powerful factor in encouraging smoking initiation. We analyzed tobacco advertising in written mass media in Spain between 2002 and 2005. METHODS: We performed an annual cross-sectional study of advertisements in the 41 most widely disseminated written mass media (nearly 10 million readers). RESULTS: In the period studied, 37% of the media included tobacco advertising (an average of 4.35 million readers). Only 4% of the media included anti-drug campaigns (an average of 0.27 million readers). Tobacco advertising increased from 2.0 to 4.7% (overall) and from 4.3 to 8.0% (in media allowing tobacco advertising). Four out of every 10 readers and one out of eight Spaniards aged 15 years or older were exposed to tobacco advertising. Fifty-six percent of advertisements included young people. CONCLUSIONS: Tobacco advertising remains prominent in written mass media in Spain and was mainly directed at young people.

Concentrations of similar finger print patterns in four race groups.

Random samples from four races were examined to determine the frequency of subjects with none, or between 5 and 10 loops or whorls; with 2 or more radial loops, and with 3 or more simple arches. Inter-racial and sex differences occur and affect the description of various concentrations as being common or unusual.

An electrophysiological study of the effects of orthographic neighborhood size on printed word perception.

In two experiments participants read words and pseudowords that belonged to either large or small lexical neighborhoods while event-related brain potentials (ERPs) were recorded from their scalps. In Experiment 1, participants made speeded lexical decisions to all items, while in Experiment 2 they engaged in a go/no-go semantic categorization task in which the critical items did not require an overt behavioral response. In both experiments, words and pseudowords produced a consistent pattern of ERP effects: items with many lexical neighbors (large neighborhoods) generated larger N400s than similar items with relatively fewer lexical neighbors (small neighborhoods). Reaction time (RT, Experiment 1), on the other hand, showed a different pattern consistent with previous behavioral studies. While words tended to produce a facilitation in RT for larger neighborhoods, pseudowords produced an inhibition effect. The findings are discussed in terms of recent theories of word recognition and the functional significance of the N400.
