BACKGROUND: It is important that response rates to postal surveys are as high as possible to ensure that the results are representative and to maximise statistical power. Previous research has suggested that any personalisation of approach helps to improve the response rate. This experiment tested whether personalising questionnaires by hand signing the covering letter improved the response rate compared with a non-personalised group where the investigator's signature on the covering letter was scanned into the document and printed. METHODS: Randomised controlled trial. Questionnaires about surgical techniques of caesarean section were mailed to 3,799 Members and Fellows of the Royal College of Obstetricians and Gynaecologists resident in the UK. Individuals were randomly allocated to receive a covering letter with either a computer printed signature or a hand written signature. Two reminders were sent to non-respondents. The outcome measures were the proportion of questionnaires returned and their time to return. RESULTS: The response rate was 79.1% (1506/1905) in the hand-signed group and 78.4% (1484/1894) in the scanned and printed signature group. There was no detectable difference between the groups in response rate or time taken to respond. CONCLUSION: No advantage was detected to hand signing the covering letter accompanying a postal questionnaire to health professionals.
INTRODUCTION: The study aimed to compare the impact of computerised physician order entry (CPOE) without decision support with hand-written prescribing (HWP) on the frequency, type and outcome of medication errors (MEs) in the intensive care unit. METHODS: Details of MEs were collected before, and at several time points after, the change from HWP to CPOE. The study was conducted in a London teaching hospital's 22-bedded general ICU. The sampling periods were 28 weeks before and 2, 10, 25 and 37 weeks after introduction of CPOE. The unit pharmacist prospectively recorded details of MEs and the total number of drugs prescribed daily during the data collection periods, during the course of his normal chart review. RESULTS: The total proportion of MEs was significantly lower with CPOE (117 errors from 2429 prescriptions, 4.8%) than with HWP (69 errors from 1036 prescriptions, 6.7%) (p < 0.04). The proportion of errors reduced with time following the introduction of CPOE (p < 0.001). Two errors with CPOE led to patient harm requiring an increase in length of stay and, if administered, three prescriptions with CPOE could potentially have led to permanent harm or death. Differences in the types of error between systems were noted. There was a reduction in major/moderate patient outcomes with CPOE when non-intercepted and intercepted errors were combined (p = 0.01). The mean baseline APACHE II score did not differ significantly between the HWP and the CPOE periods (19.4 versus 20.0, respectively, p = 0.71). CONCLUSION: Introduction of CPOE was associated with a reduction in the proportion of MEs and an improvement in the overall patient outcome score (if intercepted errors were included). Moderate and major errors, however, remain a significant concern with CPOE.
This commentary on the article by Shulman et al. examines what we understand by 'medication errors', what we mean by 'computerized physician order entry (CPOE) systems', how we measure errors, and what types of errors we are 'reducing' with CPOE systems. As the research of Shulman and colleagues highlights, much of the existing research on CPOE systems does not differentiate among: types of medication errors; consequential versus inconsequential medication errors; CPOE systems that include/exclude formal decision support packages; and the extent to which decision support information is implicitly presented to physicians via the CPOE system, for example, pull down menus with dosages. I discuss these issues and their implications for the evaluation of CPOE systems and of other emerging healthcare technologies.

Of 15 patients with writer's cramp (4 females, 11 males, mean age 36, range 23-50, mean duration 3.6 years), 13 entered a behavioural treatment. Nine received a multimodal treatment, and four EMG feedback alone. Four patients dropped out during the treatment phase. Nine patients were considered as improved at a follow-up between 1 and 9 months. A stress-coping model is put forward to account for the therapeutic effectiveness, and to explain the drop-outs. Writer's cramp seems to be related to stressful situations at work. The existence of personality and biological factors remains to be demonstrated.
An unusual case of writer's cramp in a 12-year-old deaf girl is reported. Possible aetiological and contributing factors in her environment are discussed, with particular relevance to a hysterical conversion reaction.
Sixty native-born Swedish unemployed participants with reading and writing disabilities (R&WD) participated in a 20-week educational program aimed at improving reading and writing, verbal memory, self-confidence, and flexibility of perspectives. They were tested with a comprehensive battery (interviews, questionnaires, neuropsychological tests, and tests of academic achievement) before and after the intervention. Sixteen controls, matched for sex, age, education, and nonverbal IQ, participated in the pre- and posttest sessions but received only standard unemployment interventions. The educational program participants' performance in tests assessing spelling, decoding of letters, self-confidence, and flexibility improved significantly in comparison with the controls after the intervention. A significantly larger number of the participants had obtained work or started a regular education than expected. A substantial proportion of unemployed participants have R&WD and it appears that an intensive but fairly short educational program can improve their accessibility to the labor market and their motivation for study.
Very little research has been done in the area of rehabilitation of the visual perceptual deficits observed after Balint's syndrome. This syndrome is characterized by difficulties with visual scanning, dysmetria secondary to visual perceptual deficits, and an inability to perceive more than 1 object at a time. This article describes the effects of a neuropsychological treatment protocol on a 23-year-old patient who suffered a fat embolism involving the territory of the posterior cerebral arteries. A neuropsychological evaluation carried out 12 months after the brain embolism disclosed Balint's syndrome, alexia without agraphia, visual agnosia, prosopagnosia, and memory impairments. The rehabilitation protocol included both visuoperceptual retraining and a functional program designed to provide rehabilitation in contexts that were meaningful to the patient. After 1 year of treatment, a second neuropsychological evaluation was carried out. Significant improvement was demonstrated in terms of both objective testing and the return of an integrated and productive lifestyle.
The purpose of this study was to investigate the orthographic-processing skills of typically developing 5-year-old preschool children. Of interest was whether phonotactic probabilities and/or orthotactic probabilities affected their ability to quickly learn the orthographic forms of 12 novel words. Orthographic processing was measured by the children's ability to spell and identify spellings of the novel words. Specifically, we were interested in whether (a) children quickly stored or "fast mapped" orthographic information after minimal exposure to novel words during storybook readings, (b) phonotactic and orthotactic probabilities affected orthographic fast-mapping skills, and (c) orthographic processing explained unique variance on a measure of the children's early spelling abilities. The results of this study indicated that young children quickly fast mapped orthographic information after minimal exposure to novel words, and their spelling (generation or reproduction but not recognition) was influenced by phonotactic and orthotactic probabilities. The significance of this work is that it demonstrates that preschoolers can fast map orthographic words they see onto spoken words they hear while listening to storybooks read to them and that the spelling of preschoolers is influenced uniquely by both phonological and orthographic information (probability of frequent letter and sound sequences in English words).
The purpose of this qualitative study is to understand how a sample of visiting nurses experienced the practice of home health nursing in the inner city and how they perceived the anticipated introduction of wireless, pen-based computing into their practice. Focus groups were held with visiting nurses 1 week before the introduction of the wireless, pen-based computers. The data were analyzed using Strauss and Corbin's (1990) method for concept development. The following central concepts emerged from the focus groups with visiting nurses: "Missing contact in the field," "Consumption of time writing on forms," "Using the computer to help with the practice of home health nursing," and "Home nursing is a lifeline." These concepts, based on the commentaries by visiting nurses, help one to understand the problems encountered by visiting nurses in the delivery of home health care, identify ways to incorporate evolving technologies to enhance nursing practice, and consider approaches to computer skill acquisition.
BACKGROUND AND PURPOSE: Errors in handwritten medication orders are common and can result in patient harm. We evaluated an intervention for increasing safe prescribing by medical students. METHODS: We conducted a pre-post evaluation to evaluate a brief educational intervention to increase safe prescribing by medical students. Two 1-hr, small-group, interactive educational sessions for 3rd-year medical students were held 2 weeks apart at Washington University in St. Louis. Prescribing errors were measured with a verbal transcription test. RESULTS: Twenty-eight students participated. Following the intervention, the average number of error-free orders in the 10-order test increased 5-fold from 0.82 per student to 4.54 per student, and the average number of errors and dangerous errors per student decreased from 13.96 to 7.36 (p < .0001) and from 4.75 to 2.68 (p < .0001), respectively. CONCLUSIONS: After a brief interactive educational intervention for medical students, the frequency of error-free handwritten orders increased, and prescribing errors decreased. Additional training may be required to further improve and maintain safe prescribing.
