Validation of a natural urinary stone data based infrared library searching system with artificial survey samples.

In this study we evaluated a Fourier transform IR spectrometer (Bio-Rad, USA) equipped with a search system for the analysis of urinary stones. We constructed a database of the stone library with the help of results found with X-ray diffraction analysis. In total, we included 223 stone results (213 natural and 10 spurious stones) consisting of single and composite nature. Regarding the latter we used many comparable and many diverging combinations. Applying 60 artificial referee samples that were used in the urinary stone surveys as organized by the German Society for Clinical Chemistry, we found the instrument hit quality index alone, as a measure of best spectral match not entirely sufficient in relation to acceptable performance. This was also caused by the absence of some rare components. Of those 60 survey samples, 17 did not meet the guidelines of the survey organization. These guidelines are: qualitatively correct and quantitatively within tolerance limits +/-20%. Though a number of these samples seemed irrelevant in a clinical setting, they nevertheless represent a challenge for better performance. In the second round, therefore, we included new entries and human expertise as well, which resulted in an upgrading of the score. We only missed, finally, 4 combinations, mainly related to the purine molecule, i.e. uric acid, sodium urate and ammonium urate. In conclusion, based on extension of the library, we consider the search system as acceptable. Despite that, human interpretation proved to be necessary.

Psychophysical rating of library employees' work tasks.

OBJECTIVE: This exploratory research aimed to identify the perceived physical demands of library assistants' and attendants' work tasks. STUDY DESIGN: A fixed format survey was completed by 36 library assistants and attendants from suburban and university libraries. Surveys were distributed and completed within the participants' workplaces. Descriptive statistics and Pearson's r correlations were calculated using the SPSS data analysis program. RESULTS: Data analysis revealed a hierarchical distribution of library assistants' and attendants' work tasks according to perceived physical demands. Significant Pearson's r correlations between personal factors and perceived exertion during some work tasks, were also identified. CONCLUSIONS: The hierarchical distribution of tasks revealed by this research can be used as a guide by therapists in designing graded suitable duties programs for library assistants and attendants following work-related injuries. Further task analysis is required to identify the critical physical requirements of those tasks receiving higher ratings of perceived exertion.

Access for all? A survey of health librarians in the north-west of England on provision of information to patients.

This study examined the role that health librarians could play in helping patients to find information. A questionnaire survey was sent out to 50 health librarians in the north-west of England. It examined the following: the type of library and users, access to information for patients, librarians' attitudes to provision of information to patients and their knowledge of other sources available to their users. Ninety-seven per cent of librarians said that they could recommend quality information sources to patients, but many suggested that there were practical problems in allowing patients to use health libraries due to lack of appropriate resources, facilities and funding. Advantages of health library involvement in patient information include having a local point of contact for patients and the ability of librarians to find, evaluate and organize good-quality resources. However, health library staff may not have enough time to answer enquiries from the public and may lack training in dealing with patients. Innovation, especially in developing on-line services, could offer a way to provide a service without overloading the physical requirements of a library. Librarians could also collaborate with other staff to improve patient information.

Role of the hospital library within the hospital system.

The results of a survey of hospital administrators, attending staff and house staff physicians, librarians, library committee chairmen, and nursing staff in five Northeastern Ohio hospitals concerning the status of the hospital library within the total hospital system are related. Results indicate that hospital libraries operate in the "fringe" area of the hospital system. A concentric-circle figure indicates the present position of the majority of hospital libraries surveyed. The future relationship of the library within the hospital system has also been represented by a concentric-circle figure.

Information needs of the rural physician: a descriptive study.

The study was designed to describe the information needs and the information-seeking behavior of rural physicians. Data were collected from twelve rural physicians in Central Florida through face-to-face interviews and observation. From a review of 144 patient charts, 48 produced unique, factual patient care questions. Seventy-five percent of the questions were on treatment, 14.7% on diagnosis, 8.3% on etiology, and 2.1% on the psychological aspects of disease. All physicians in the survey relied on colleagues; eleven attended medical meetings; nine subscribed to medical journals, and nine owned medical textbooks. Of the physicians with access to a hospital library, two used the library frequently while ten seldom used the library. Lack of time due to heavy workloads was an obstacle to systematic information retrieval. Rural physicians need immediate access to high-quality, synthesized answers to specific patient care questions at the time of patient contact. Information must be concise and up-to-date, although not necessarily state-of-the-art. A database composed of selected textbooks with integrated keyword access would meet the criteria. In addition, a computerized expert system focused on rural physicians' information needs is a possible remedy for the existing problem.

LISTENing to healthcare students: the impact of new library facilities on the quality of services.

Following a low assessment of 'Learning resources' provision by the Quality Assurance Agency, the librarian of Homerton College, School of Health Studies commenced the LISTEN Project, a long-term study to monitor the effects of planned interventions on the quality of library provision. Surveys of entry-to-register student nurses & midwives were conducted in 1999 and 2001 by extensive questionnaires, inviting Likert-scaled and free text responses. Following a college relocation, students made greater than expected use of a new health studies library in Cambridge, and significantly less use of the local teaching hospital library. Using both a satisfaction index and a non-parametric test of mean scores, student evaluation of library services in Cambridge significantly improved following relocation. The physical accommodation and location of library services remain important to healthcare students. Identifiable improvements to the quality of services, however, will overcome initial resistance to change. Education providers must ensure the best mix of physical and electronic services for students who spend much of their time on clinical placement.

Medical school libraries' handling of articles that report invalid science.

In 1989-90 the authors conducted a nationwide study to examine how academic medical libraries handled articles that report invalid science and to determine the effectiveness of any policies implemented to limit the use of such articles. Ninety-five of the 127 medical school libraries the authors surveyed completed questionnaires analyzing policy and attitude issues. Eighty-four of these libraries manually reviewed the available copies they held of ten retracted articles. Of the 811 copies of the retracted, invalid articles reviewed, 742 (91.5%) were not tagged as being invalid. Seventy-nine percent of the libraries had tagged none of the retracted studies and only 16% had policies for managing articles that report invalid science. Academic librarians reflected a common attitude against perceived library censorship and emphasized the user's role in assuring validity. The nation's medical libraries, at least in part by intent, do not commonly identify or have policies to handle the invalid articles they hold. The authors conclude that biomedical researchers, clinicians, and teachers should not assume published studies held in libraries are inherently valid. The lack of stated policy and the disparate assumptions about the role libraries play in this area may perpetuate the use of invalid articles.

Errata control in biomedical journals.

Errata notices published in medical journals are investigated by (1) a six-month study of those currently received by a medium-sized medical library; (2) a survey on the way medical libraries handle them, and (3) interviews with researchers to determine their ideas about errata. Since there is a wide variation at present in errata control practices, the question is raised about the extent of a library's responsibility with regard to errata.

Ethics in health sciences librarianship.

Against a background of discussion about drafting of an ethical code for librarians and a review of articles confronting ethical issues in librarianship, the authors surveyed the 150 institutional members of the Health Science Librarians of Illinois (HSLI) regarding their perceptions of ethical concerns. Among the issues addressed in the survey are library organization, personnel policies, and professional competency, along with the traditional concerns of professional versus personal values, privacy and confidentiality, access to materials, and materials selection criteria in a health sciences context. Based on a 60% response rate, survey results indicate widespread agreement on some issues and a conspicuous lack of consensus on others. Further research is suggested in order to assess the need for a separate ethical code for health sciences librarians.

Accuracy of telephone reference service in health sciences libraries.

Six factual queries were unobtrusively telephoned to fifty-one U.S. academic health sciences and hospital libraries. The majority of the queries (63.4%) were answered accurately. Referrals to another library or information source were made for 25.2% of the queries. Eleven answers (3.6%) were inaccurate, and no answer was provided for 7.8% of the queries. There was a correlation between the number of accurate answers provided and the presence of at least one staff member with a master's degree in library and information science. The correlation between employing a librarian certified by the Medical Library Association (MLA) and providing accurate answers was significant. The majority of referrals were to specific sources. If these "helpful referrals" are counted with accurate answers as correct responses, they total 76.8% of the answers. In a follow-up survey, five libraries stated that they did not provide accurate answers because they did not own an appropriate source. Staff-related problems were given as reasons for other than accurate answers by two of the libraries, while eight indicated that library policy prevented them from providing answers to the public.

Construction of a nurse shark (Ginglymostoma cirratum) bacterial artificial chromosome (BAC) library and a preliminary genome survey.

BACKGROUND: Sharks are members of the taxonomic class Chondrichthyes, the oldest living jawed vertebrates. Genomic studies of this group, in comparison to representative species in other vertebrate taxa, will allow us to theorize about the fundamental genetic, developmental, and functional characteristics in the common ancestor of all jawed vertebrates. AIMS: In order to obtain mapping and sequencing data for comparative genomics, we constructed a bacterial artificial chromosome (BAC) library for the nurse shark, Ginglymostoma cirratum. RESULTS: The BAC library consists of 313,344 clones with an average insert size of 144 kb, covering ~4.5 x 1010 bp and thus providing an 11-fold coverage of the haploid genome. BAC end sequence analyses revealed, in addition to LINEs and SINEs commonly found in other animal and plant genomes, two new groups of nurse shark-specific repetitive elements, NSRE1 and NSRE2 that seem to be major components of the nurse shark genome. Screening the library with single-copy or multi-copy gene probes showed 6-28 primary positive clones per probe of which 50-90% were true positives, demonstrating that the BAC library is representative of the different regions of the nurse shark genome. Furthermore, some BAC clones contained multiple genes, making physical mapping feasible. CONCLUSION: We have constructed a deep-coverage, high-quality, large insert, and publicly available BAC library for a cartilaginous fish. It will be very useful to the scientific community interested in shark genomic structure, comparative genomics, and functional studies. We found two new groups of repetitive elements specific to the nurse shark genome, which may contribute to the architecture and evolution of the nurse shark genome.

The value and impact of information provided through library services for patient care: a systematic review.

OBJECTIVE: An updated systematic review was carried out of research studies looking at the value and impact of library services on health outcomes for patients and time saved by health professionals. METHODS: A comprehensive systematic search was undertaken of the published literature to September 2003 in ERIC, LISA, MEDLINE, PREMEDLINE, EMBASE, the Cochrane Controlled Trials Register and Google. Some handsearching was carried out, reference lists were scanned and experts in the field were contacted. Twenty-eight research studies of professionally led libraries for health-care staff, including clinical librarian projects, met the inclusion criterion of at least one health or 'time saved' outcome. Papers were critically appraised using internationally accepted criteria. Data were extracted and results were summarised using a narrative format as the studies were heterogeneous and precluded a statistical analysis. RESULTS: There is evidence of impact from both traditional and clinical librarian services. The higher quality studies of traditional services measured impacts of 37-97% on general patient care, 10-31% on diagnosis, 20-51% on choice of tests, 27-45% on choice of therapy and 10-19% on reduced length of stay. Four studies of clinical librarian projects suggested that professionals saved time as a result of clinical librarian input, and two of these studies showed evidence of cost-effectiveness. However, the clinical librarian studies were generally smaller, with poorer quality standards. CONCLUSIONS: Research studies suggest that professionally led library services have an impact on health outcomes for patients and may lead to time savings for health-care professionals. The available studies vary greatly in quality but the better quality studies also suggest positive impacts. Good practice can be gathered from these studies to guide the development of a pragmatic survey for library services that includes the direct effects for patients among the outcome measures.

Document delivery capabilities of major biomedical libraries in 1968: results of a national survey employing standardized tests.

The standardized Document Delivery Tests (DDT's) developed earlier (Bulletin 56: 241-267, July 1968) were employed to assess the capability of ninety-two medical school libraries for meeting the document needs of biomedical researchers, and the capability of fifteen major resource libraries for filling I-L requests from biomedical libraries. The primary test data are summarized as statistics on the observed availability status of the 300 plus documents in the test samples, and as measures expressing capability as a function of the mean time that would be required for users to obtain test sample documents. A mathematical model is developed in which the virtual capability of a library, as seen by its users, equals the algebraic sum of the basic capability afforded by its holdings; the combined losses attributable to use of its collection, processing, relative inacessibility, and housekeeping problems; and the gain realized by coupling with other resources (I-L borrowing). For a particular library, or group of libraries, empirical values for each of these variables can be calculated easily from the capability measures and the status statistics. Regression equations are derived that provide useful predictions of basic capability from collection size. The most important result of this work is that cost-effectiveness analyses can now be used as practical decision aids in managing a basic library service. A program of periodic surveys and further development of DDT's is recommended as appropriate for the Medical Library Association.

User services offered by medical school libraries in 1968: results of a national survey employing new methodology.

The breadth and depth of services that ninety-two medical school libraries offer to individual users were ascertained by interviewing the heads of these libraries, employing a standardized inventory procedure developed earlier (Bulletin 56:380-403, Oct. 1968). Selected aspects of the descriptive data obtained on services to faculty and to medical students are presented and commented upon. Comparisons with the findings of earlier surveys suggest that increases in the staffs and budgets of medical school libraries over the past two decades have gone largely to supporting a rapidly increasing volume of service, rather than to any striking increase in the breadth and depth of services. To facilitate summarization and comparisions among libraries the descriptive data were weighted and converted to quantitative measures; the weighting scheme was established by a group of five academic medical librarians to reflect the relative values the group assigned to different services. One of these quantitative measures, the percentage score for overall services relative to the optimal library, summarizes a library's services in a single figure. On this measure, medical school libraries ranged from 38 percent to 87 percent; the median overall score was 63 percent. Results of some exploratory analyses are described; these analyses attempted to find explanations for the observed differences among libraries and among geographical regions on the quantitative measures. Present and potential uses of the survey data for managerial and research purposes are discussed. One of the most important of these uses is in establishing and implementing standards-activities which should be carried out by the library profession itself-and recommendations are made for a program of such activities that is appropriate for the Medical Library Association.

Indoor air quality in the university libraries of Modena (Italy).

We carried out a survey in 16 libraries of the University of Modena, Northern Italy, to assess the indoor exposure to volatile organic compounds (VOCs), including formaldehyde, and total dusts. Data were collected on the main structural characteristics of the buildings; indoor microclimate parameters, such as temperature, relative humidity and ventilation rate were measured and air samples taken inside and outside the libraries. The mean value of total dusts was 190 +/- 130 microg/m3 with a wide range of values. Formaldehyde was found in only ten out of 16 libraries and the indoor concentrations ranged from 1.70 to 67.8 microg/m3 with an average value of 32.7 +/- 23.9 microg/m3. On the whole, VOCs were present in all the libraries investigated with an average value was 433 +/- 267 microg/m3 (range 102-936 microg/m3). No correlation was found among VOCs, formaldehyde and total dusts nor was a significant association observed with microclimatic parameters or the structural characteristics of the buildings. The general situation found in this study suggests no major problems related to indoor pollution. However, some of the pollutants investigated such as total dust and total VOCs deserve further investigation. It is important to identify the possible sources of contaminants and to define the relationship between indoor and outdoor levels of pollutants more accurately, taking into account the effects of air recycling due to natural ventilation systems.
