KWIC. IS IT QUICK?

In recent months several widely circulated publications have exploited the concept of key-word-in-context (KWIC) indexing. Indexes prepared through KWIC techniques are based entirely on the permuted titles of material to be analyzed and are produced at high speed with the aid of electronic computers. KWIC indexes appear to have been received with approval by scientists, whereas many librarians regard them with misgivings and are concerned about the discontinuance of certain earlier conventional subject indexes. This paper presents some of the difficulties encountered by reference librarians who have used KWIC indexes in the course of their work. A simple exercise is described which tests the speed with which a KWIC and two other indexes lead to the solution of selected reference problems. KWIC proved to be a tool which led quickly to the desired information.

A comprehensive indexed bibliography data base using a micro computer.

A comprehensive index has been developed for coding and cataloguing alcohol literature. A system has been implemented using a commercial data base management program and a micro computer for computerising the references. In addition to the index code and citation the user can also enter an abstract and a description of the article. References can be added to the computer, edited, searched for, displayed on screen, typed on paper, or sent to a text file using a selection of criteria entered by the user. When a search is performed the printout can include the abstract of each paper similar to that obtained from larger bibliographic services. Such a system is beneficial for personal study, for writing books, articles and theses and for use by departments and small libraries.

Assessing population health care need using a claims-based ACG morbidity measure: a validation analysis in the Province of Manitoba.

OBJECTIVES: To assess the ability of an Adjusted Clinical Group (ACG)-based morbidity measure to assess the overall health service needs of populations. Data Sources/Study Setting. Three population-based secondary data sources: registration and health service utilization data from fiscal year 1995-1996; mortality data from vital statistics reports from 1996-1999; and Canadian census data. The study included all continuously enrolled residents in the universal health care plan in Manitoba. STUDY DESIGN: Using 60 small geographic areas as the units of analysis, we compared a population-based "ACG morbidity index," derived from individual ACG assignments in fiscal year 1995-1996, with the standardized mortality ratio (ages < 75 years) for 1996-1999. Key variables included a population-based socioeconomic status measure and age- and sex-standardized physician utilization ratios. DATA EXTRACTION METHODS: The ACGs were assigned based on the complement of diagnoses assigned to persons on physician claims and hospital separation abstracts. The ACG index was created by weighting the ACGs using average health care expenditures. PRINCIPAL FINDINGS: The ACG morbidity index had a strong positive linear relationship with the subsequent rate of premature death in the small areas of Manitoba. The ACG index was able to explain the majority of the relationships between mortality and both socioeconomic status and physician utilization. CONCLUSIONS: In Manitoba, ACGs are closely related to premature mortality, commonly accepted as the best single indicator for health service need in populations. Issues in applying ACGs in settings where needs adjustment is a primary objective are discussed.

[AN ATTEMPT AT AUTOMATION OF DOCUMENTATION IN MEDICINE].

Since there is still little mechanization in medical documentation, it seemed interesting to study an attempt at automation in a medical specialty, cancerology. The author explains the difficulties which derive from the multidisciplinary nature of the specialty itself and from the diversity of its users' needs. The system used is Filmorex, which is described in some detail. The author then examines the problems connected with the development of a documentation language and describes an attempt to solve these problems in a documentation center of moderate size (10,000 documents per year).

Inpatient versus other settings for detoxification for opioid dependence.

BACKGROUND: There are a complex range of variables that can influence the course and subjective severity of opioid withdrawal. There is a growing evidence for the effectiveness of a range of medically-supported detoxification strategies, but little attention has been paid to the influence of the setting in which the process takes place. OBJECTIVES: To evaluate the effectiveness of any inpatient opioid detoxification programme when compared with all other time-limited detoxification programmes on the level of completion of detoxification, the intensity and duration of withdrawal symptoms, the nature and incidence of adverse effects, the level of engagement in further treatment post-detoxification, and the rates of relapse post-detoxification. SEARCH STRATEGY: Electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL - The Cochrane Library Issue 3, 2004); MEDLINE (January 1966-March 2004); EMBASE (January 1988-March 2004); PsycInfo (January 1967-March 2004); CINAHL (January 1982-March 2004). In addition the Current Contents, Biological Abstracts, Science Citation Index and Social Sciences Index were searched. SELECTION CRITERIA: Randomised controlled clinical trials comparing inpatient opioid detoxification (any drug or psychosocial therapy) with other time-limited detoxification programmes (including residential units that are not staffed 24 hours per day, day-care facilities where the patient is not resident for 24 hours per day, and outpatient or ambulatory programmes, and using any drug or psychosocial therapy). DATA COLLECTION AND ANALYSIS: All abstracts were independently inspected by two reviewers (ED & JI) and relevant papers were retrieved and assessed for methodological quality using Cochrane Reviewers' Handbook criteria. MAIN RESULTS: Only one study met the inclusion criteria. This did not explicitly report the number of participants in each group that successfully completed the detoxification process, but the published data allowed us to deduce that 7 out of 10 (70%) in the inpatient detoxification group were opioid-free on discharge, compared with 11 out of 30 (37%) in the outpatient group. There was very limited data about the other outcomes of interest. AUTHORS' CONCLUSIONS: This review demonstrates that there is no good available research to guide the clinician about the outcomes or cost-effectiveness of inpatient or outpatient approaches to opioid detoxification.

Charlson Index is associated with one-year mortality in emergency department patients with suspected infection.

OBJECTIVES: A patient's baseline health status may affect the ability to survive an acute illness. Emergency medicine research requires tools to adjust for confounders such as comorbid illnesses. The Charlson Comorbidity Index has been validated in many settings but not extensively in the emergency department (ED). The purpose of this study was to examine the utility of the Charlson Index as a predictor of one-year mortality in a population of ED patients with suspected infection. METHODS: The comorbid illness components of the Charlson Index were prospectively abstracted from the medical records of adult (age older than 18 years) ED patients at risk for infection (indicated by the clinical decision to obtain a blood culture) and weighted. Charlson scores were grouped into four previously established indices: 0 points (none), 1-2 points (low), 3-4 points (moderate), and > or =5 points (high). The primary outcome was one-year mortality assessed using the National Death Index and medical records. Cox proportional-hazards ratios were calculated, adjusting for age, gender, and markers of 28-day in-hospital mortality. RESULTS: Between February 1, 2000, and February 1, 2001, 3,102 unique patients (96% of eligible patients) were enrolled at an urban teaching hospital. Overall one-year mortality was 22% (667/3,102). Mortality rates increased with increasing Charlson scores: none, 7% (95% confidence interval [CI] = 5.4% to 8.5%); low, 22% (95% CI = 19% to 24%); moderate, 31% (95% CI = 27% to 35%); and high, 40% (95% CI = 36% to 44%). Controlling for age, gender, and factors associated with 28-day mortality, and using the "none" group as a reference group, the Charlson Index predicted mortality as follows: low, odds ratio of 2.0; moderate, odds ratio of 2.5; and high, odds ratio of 4.7. CONCLUSIONS: This study suggests that the Charlson Index predicts one-year mortality among ED patients with suspected infection.

Structured abstracts in MEDLINE, 1989-1991.

OBJECTIVE: To characterize the structured abstracts in biomedical journals indexed in MEDLINE over a three-year period as an initial step in exploring their utility in enhancing bibliographic retrieval. DESIGN: The study examined the occurrence of structured abstracts in MEDLINE from March 1989 to December 1991, characteristics of MEDLINE records for articles with structured abstracts, editorial policies of six selected MEDLINE journals on structured abstracts, and a sample of twenty-five structured abstracts from the six journals. RESULTS: The study revealed that the number of structured abstracts in MEDLINE and the number of MEDLINE journals publishing structured abstracts increased substantially between 1989 and 1991. On average, articles with structured abstracts had more access points (Medical Subject Heading [MeSH] terms and text words) than MEDLINE articles as a whole. The average length of the structured abstract was greater than the average length of all abstracts in MEDLINE. CONCLUSIONS: The presence of structured abstracts may be associated with other article characteristics that lead to the assignment of a higher average number of MeSH headings or may itself contribute to the assignment of more headings. The variations in the structured-abstract formats prescribed by different journals may complicate the exploitation of these abstracts in bibliographic retrieval systems. More research is needed on a number of questions related to the quality and utility of structured abstracts.
