A co-ordinated IT system for the improved management of the blood supply.

Historically, most computer systems have been backward looking and have been introduced as a method of dealing with increasingly complex practices. For the Service to exploit the potential benefits of information technology, today's systems must be forward looking, support the Service's strategy and help shape the Service, not merely reflect it. To do this the starting point for the design of the Service's information systems must be the needs of the customer. It is therefore intended to replace the Service's current 12 incompatible computer systems with a single, standard system. Benefits will begin to be realized immediately following implementation of the chosen system in the first site; however, the benefits will not be fully realized until after successful implementation of the last site. The following is a non-exhaustive list of some of the benefits that the Service is seeking to achieve by implementing a coordinated IT system.

Guidelines, practice policies, and parameters: the case for geriatrics.

OBJECTIVE: As the population ages, the care of older persons becomes more important. At the same time, practice guidelines that provide recommendations for appropriate care are being published in greater numbers. The purpose of this work is to determine the proportion of guidelines that contain specific information about older persons. DESIGN: Through a random sample of published guidelines listed in the AMA Directory of Practice Parameters, 1992 Edition, we determined the proportion of guidelines that contain specific age-related information. We also determined if, over time, there was a difference in the proportion of practice guidelines containing information about older persons. RESULTS: 45.9% (95% CI, range 33.4-58.4) of guidelines that could conceivably pertain to older persons contain no age information; 24.6% (95% CI, range 13.8-35.4) of guidelines contain information only about persons less than 65 years of age; 29.5% (95% CI, range 18.1-41.0) of guidelines contain specific information about older persons. Moreover, there were no secular trends in the proportion of guidelines pertaining to older persons. CONCLUSIONS: Only a minority of practice guidelines contain information about older persons. Possible causes and solutions to this shortfall are discussed.

Maintenance of cooling towers following two outbreaks of Legionnaires' disease in a city.

This survey assessed the maintenance of evaporative cooling towers in Glasgow, following two Legionnaires' disease outbreaks. Information was obtained from 76 of 81 premises and a maintenance score was calculated for each of 174 towers. The quality of maintenance was extremely varied (range of maintenance scores, 8-30; mean, 22 (S.D., 5.0); median, 23; maximum possible, 33) and some towers were neglected. Breaches of maintenance principles were mainly structural and organizational, e.g. inadequate drift control, rather than failure to use chemicals. Low maintenance scores were associated with no log book, no guidelines, no change in procedures in last 5 years, solitary cooling towers, and towers on industrial premises. Despite intense publicity the standard of cooling tower maintenance in Glasgow remained a concern. Information campaigns directed at those responsible for cooling-tower maintenance are necessary.

An investigation into factors that may influence tonsil morphology.

To investigate whether tonsillar size was related to human morphology, age or duration of disease, 100 consecutive patients undergoing tonsillectomy for recurrent tonsillitis were investigated. The lengths, widths and volumes of each resected tonsil were measured and compared with patient characteristics ascertained on the day before surgery. The volume of tonsillar tissue was directly related to height (p = 0.46, P less than 0.001) and weight (p = 0.45, P less than 0.001) and age, but at any age (or body size) there was a wide range of tonsil size. A weak inverse relationship was found with the duration of recurrent tonsillitis. Tonsil size is of no relevance in the assessment of recurrent tonsillitis or adenoid hypertrophy.

Adenoid infection: its relationship to otitis media, glue ear and tonsillitis.

In a prospective study, 69 children admitted for adenoidectomy were divided into 4 subgroups according to their symptomatology. These were: nasal obstruction alone; glue ear; recurrent ear aches and probable otitis media; and recurrent sore throats and probable tonsillitis. The adenoids removed were bacteriologically analysed to assess both the spectrum of organisms present and the colony counts per gram of adenoid tissue (10(5) organisms per gram was regarded as representing infection). There was no significant difference between the subgroups with regard to either the presence of infection or the spectrum of organisms grown. We conclude that while infection in the adenoid bed must be involved in the pathogenesis of bacterial otitis media, the concentration of organisms present in the adenoids is unimportant and other factors must be responsible for the migration of organisms up the Eustachian tube.

Squamous epithelium in the subglottic region of paediatric larynges.

A macroscopic staining method was used to display and measure the extent of squamous epithelium in the subglottis of stillborn babies and of babies less than 3 months old. Squamous epithelium was found to be present in some babies without a previous history of intubation (3 of 8) and in some stillborn babies (3 of 11). Squamous epithelium in the subglottic space of the human is thus present at birth.

A pediatric screening examination for psychosocial problems.

In an effort to avert the cumulative effects of unresolved emotional problems on children's social and school adjustment, a psychosocial phase was added to a pediatric multiphasic examination. Based upon a cumulative stress concept, the screening procedures included child behavior and family stress questionnaires for parents, and abbreviated standard psychological tests for children, administered by specially trained aides. Computerized results were reported to the child's pediatrician. Follow-up by mental health counselors attached to the pediatric clinic was provided for patients identified as being at high risk of serious psychosocial problems. Evidence of validity of the screen, factors affecting the scores, and effectiveness of clinical follow-up of high-risk patients are discussed. Valid semicomputerized screening of school-age children for serious psychosocial problems can be carried out routinely and at relatively low cost by paraprofessional personnel in a pediatric setting. Impediments to effective use of the screening results on the part of both health care provider and patient are discussed.

The health care team. The role of pediatric nurse practitioners as viewed by California pediatricians.

A single-mailing questionnaire surveyed attitudes of members of District IX, American Academy of Pediatrics (California) toward the role of the pediatric nurse practitioner (pnp). Responses from 568 members (53%) represented a broad range of age, practice type (58% group, 25% solo, 17% "other"), geographic location, and opinion. The most favorable attitudes toward pnp use were expressed by young pediatricians in large-group and "other" categories; least favorable were solo practitioners older than 60 years. Practice type was more important than age. Most respondents expressed the opinion that a pediatrician-pnp team approach would enrich both professions, and that parental acceptance of the pnp was likely; but that pnp use would not reduce costs. Majorities favored the concept of the pnp as part of the practice team but under constant pediatrician surveillance: seeing the patient for part of the visit and participating under supervision in care for minor illness, but not replacing the pediatrician even in well-child care. Some pnps hope for a more independent role on the pediatrician-pnp team. Modification of both pediatrician and pnp ideas appears requisite to a team approach that will satisfy both professional groups and the public.

Verrucous carcinoma of the oesophagus and achalasia.

A 67 year old male caucasian clerical worker with a background of long-standing gastro-oesophageal reflux-like dyspepsia and bronchiectasis presented to a tertiary hospital gastroenterology unit with a recent onset of dysphagia. An initial diagnosis of achalasia was made and within 1 year an established verrucous carcinoma of the upper oesophagus had developed. The tumour was inoperable due to tracheal invasion and therefore palliative treatment was given. The patient developed a tracheo-oesophageal fistula and died of pneumonia. Thus, verrucous squamous cell carcinoma of the oesophagus can occur with achalasia.
