[The telephone interview: the methodological strategy for collecting population data].

The interview by telephone is not an ordinary procedure to obtain investigation data. By knowing that is rarely used in Brazil, the study was planned aiming to: identify the individuals' characteristics who answer the sampled telephones; raise the interviews' statements about the operational technique and evaluate the telephone used as data collection procedure. The data indicate that most of the people who were interviewed, were females, between 30 and 40 years old and housewives. The interviewers considered between 30 and 40 years old and housewives. The interviewers considered the experience interesting, in despite of the difficulty to maintain people talking on the phone. The authors state that the interview by telephone is an efficient and fast way of bringing up data for investigation which aims to raise opinions about certain matters.

Development of a multicenter interventional cardiology database: the Blue Cross Blue Shield of Michigan Cardiovascular Consortium (BMC2) experience.

The technical challenges in the development of a quality-controlled registry of percutaneous coronary interventions (PCIs) are currently unknown. This article describes the authors' experience in the development of a regional, quality-controlled PCI registry. In 1996, 16 centers in Michigan were invited to participate in a multicenter PCI registry. Nine centers agreed to a pilot data collection and, as of July 2001, eight centers are still actively collecting data. An Oracle database was developed by the coordinating center. A common data collection form and a standard set of definitions were agreed on during several meetings. Data validity was insured through review of each form by a trained nurse, by automatic database diagnostic routines, and by site visits that included a review of the catheterization laboratory logs and a review of randomly selected charts. The average number of forms requiring query resolution was 33% in 1997 (range 7-76%), and it decreased to 5% in 1999 (range 1.4-10%). The most commonly queried variables were outcomes prior to discharge, lesion category, lesion complexity, date of birth, device used, gender, postprocedural percent stenosis, presence of left main disease, and MI date. Invalid dates, identification of the doctor, the presence of duplicate forms, and of duplicate outcomes were additional common queries generated by the internal diagnostic routines. In conclusion, the number of queries and diagnostic reports generated in the database suggests that the development of a quality-controlled PCI registry requires the institution of a careful diagnostic and data quality assessment system.

Comparison between research data and routinely collected register data for studying childhood health.

Cohort studies are usually based on detailed information gathered on a limited number of individuals. Increasing collection of administrative registers offers an alternative method to gather health data. In the first study health information from birth until the age of seven years on 8708 children born in the two most northern provinces of Finland in 1985-86 was gathered through questionnaires, medical record reviews, medical examinations and some register data. In the second study, similar information on 8222 children born in the same provinces in 1987 was gathered using administrative registers. Both data collection methods gave equal results for mortality, long-term medication. and cumulative incidence of diabetes and intellectual disabilities. The register data identified more children with delayed development, but less children with long-term illness (77% of the level identified by the research data), with asthma (74%), and with epilepsy (40%). The register data was unsuitable for investigating hearing and vision disorders. The administrative data gave a gender ratio similar to that of the research data for two of the variables with poor coverage (asthma and epilepsy), but identified more boys with long-term illness in general than the research data. Administrative registers are useful for studying many long-term health problems, e.g. those resulting in hospital care or social benefits or those registered in vital statistics. Specific cohort studies with separate data collection is still needed to study for example outpatient care, self-assessed health, growth and development.

MIRD pamphlet no. 16: Techniques for quantitative radiopharmaceutical biodistribution data acquisition and analysis for use in human radiation dose estimates.

This report describes recommended techniques for radiopharmaceutical biodistribution data acquisition and analysis in human subjects to estimate radiation absorbed dose using the Medical Internal Radiation Dose (MIRD) schema. The document has been prepared in a format to address two audiences: individuals with a primary interest in designing clinical trials who are not experts in dosimetry and individuals with extensive experience with dosimetry-based protocols and calculational methodology. For the first group, the general concepts involved in biodistribution data acquisition are presented, with guidance provided for the number of measurements (data points) required. For those with expertise in dosimetry, highlighted sections, examples and appendices have been included to provide calculational details, as well as references, for the techniques involved. This document is intended also to serve as a guide for the investigator in choosing the appropriate methodologies when acquiring and preparing product data for review by national regulatory agencies. The emphasis is on planar imaging techniques commonly available in most nuclear medicine departments and laboratories. The measurement of the biodistribution of radiopharmaceuticals is an important aspect in calculating absorbed dose from internally deposited radionuclides. Three phases are presented: data collection, data analysis and data processing. In the first phase, data collection, the identification of source regions, the determination of their appropriate temporal sampling and the acquisition of data are discussed. In the second phase, quantitative measurement techniques involving imaging by planar scintillation camera, SPECT and PET for the calculation of activity in source regions as a function of time are discussed. In addition, nonimaging measurement techniques, including external radiation monitoring, tissue-sample counting (blood and biopsy) and excreta counting are also considered. The third phase, data processing, involves curve-fitting techniques to integrate the source time-activity curves (determining the area under these curves). For some applications, compartmental modeling procedures may be used. Last, appendices are included that provide a table of symbols and definitions, a checklist for study protocol design, example formats for quantitative imaging protocols, temporal sampling error analysis techniques and selected calculational examples. The utilization of the presented approach should aid in the standardization of protocol design for collecting kinetic data and in the calculation of absorbed dose estimates.

Rapid improvement teams.

BACKGROUND: Suggestions, most of which are supported by empirical studies, are provided on how total quality management (TQM) teams can be used to bring about faster organizationwide improvements. SUGGESTIONS: Ideas are offered on how to identify the right problem, have rapid meetings, plan rapidly, collect data rapidly, and make rapid whole-system changes. Suggestions for identifying the right problem include (1) postpone benchmarking when problems are obvious, (2) define the problem in terms of customer experience so as not to blame employees nor embed a solution in the problem statement, (3) communicate with the rest of the organization from the start, (4) state the problem from different perspectives, and (5) break large problems into smaller units. Suggestions for having rapid meetings include (1) choose a nonparticipating facilitator to expedite meetings, (2) meet with each team member before the team meeting, (3) postpone evaluation of ideas, and (4) rethink conclusions of a meeting before acting on them. Suggestions for rapid planning include reducing time spent on flowcharting by focusing on the future, not the present. Suggestions for rapid data collection include (1) sample patients for surveys, (2) rely on numerical estimates by process owners, and (3) plan for rapid data collection. Suggestions for rapid organizationwide implementation include (1) change membership on cross-functional teams, (2) get outside perspectives, (3) use unfolding storyboards, and (4) go beyond self-interest to motivate lasting change in the organization. CONCLUSIONS: Additional empirical investigations of time saved as a consequence of the strategies provided are needed. If organizations solve their problems rapidly, fewer unresolved problems may remain.

Pulse oximetry for perioperative monitoring.

BACKGROUND: Monitoring with pulse oximetry might improve patient outcome by enabling an early diagnosis and consequently, correction of perioperative events that might cause postoperative complications or even death. Only a few randomised clinical trials of pulse oximetry have been performed during anaesthesia and in the recovery room which describe perioperative hypoxaemic events, postoperative cardiopulmonary complications and cognitive dysfunction. OBJECTIVES: To study the effect of perioperative monitoring with pulse oximetry to clearly identify the adverse outcomes that might be prevented or improved by the use of pulse oximetry. SEARCH STRATEGY: Trials were identified by computerised searches of the Cochrane Library, MEDLINE, EMBASE, and by checking the reference lists of trials and review articles. SELECTION CRITERIA: All controlled trials that randomised patients to either pulse oximetry or no pulse oximetry during the perioperative period, including the operating and recovery room. DATA COLLECTION AND ANALYSIS: We collected data in relation to events detectable by pulse oximetry, any serious complications that occurred during anaesthesia or in the postoperative period, intra- or postoperative mortality, and duration of recovery or intensive care stay. Formal statistical synthesis of individual trials was not performed in view of the variety of outcomes studied. MAIN RESULTS: Searching identified six reports; four studies with data from a total of 21,773 patients were considered eligible for analysis. Only two studies specifically addressed the outcomes in question; both found no effect on the rate of postoperative complications using perioperative pulse oximetry. Two studies used hypoxaemia detectable by pulse oximetry to assess the value of perioperative monitoring, although outcomes were not given. It was found that hypoxaemia was reduced in the pulse oximetry group both in the operating theatre and in the recovery room. During observation in the recovery room, the incidence of hypoxaemia in the pulse oximetry group was 1.5-3 times less. The postoperative cognitive function using the Wechsler memory scale and continuous reaction time was independent of perioperative monitoring with pulse oximetry. The other study showed that postoperative complications occurred in 10% of the patients in the oximetry group and in 9.4% in the control group. The two groups did not differ in cardiovascular, respiratory, neurologic, or infectious complications. The duration of hospital stay was a median of 5 days in both groups, and an equal number of in-hospital deaths was registered in the two groups. REVIEWER'S CONCLUSIONS: The studies confirmed that pulse oximetry can detect hypoxaemia and related events. However, we have found no evidence that pulse oximetry affects the outcome of anaesthesia. The conflicting subjective and objective results of the studies, despite an intense, methodical collection of data from a relatively large population, indicates that the value of perioperative monitoring with pulse oximetry is questionable in relation to improved reliable outcomes, effectiveness and efficiency.

Telemedical database of Hodgkin's disease.

The creation of a complex telemedical system oriented towards childhood Hodgkin's disease has been undertaken at the Department of Bioinformatics and Telemedicine of the Jagiellonian University Medical College in cooperation with the Department of Oncology and Pediatric Hematology of the Polish-American Institute of Pediatrics, JU MC. Data collecting, data processing and data transmission is aimed to aid and/or supervise surgical and drug treatment. The Tele-Database of Childhood Hodgkin's Disease (TDCHD) is not a simple Internet database project. A few hundred data items are presented in each patient's record, covering the complete medical treatment period. Efficient management and proper data protection are necessary for a medical database. Therefore, the interface for entering data has been divided into several parts. Each part is subjected to separate editing and transfer. A double-layer debugging system has been applied in the program: the first pass occurs on the client side (programmed in JavaScript and XML), the second - on the server side (programmed in PHP). Strict authorization is requested for all participants. Clinical data collected according to management standards and information governance (data quality, security and confidentiality) is organized in a way that facilitates practical and scientific use.

Measuring clinical performance using routinely collected clinical data.

Following the well-publicized problems with paediatric cardiac surgery at the Bristol Royal Infirmary, there is wide public interest in measures of hospital performance. The Kennedy report on the BRI events suggested that such measures should be meaningful to the public, case-mix-adjusted, and based on data collected as part of routine clinical care. We have found that it is possible to predict in-hospital mortality (a measure readily understood by the public) using simple routine data-age, mode of admission, sex, and routine blood test results. The clinical data items can be obtained at a single venesection, are commonly collected in the routine care of patients, are already stored on hospital core IT systems, and so place no extra burden on the clinical staff providing care. Such risk models could provide a metric for use in evidence-based clinical performance management. National application is logistically feasible.

Benefits of collecting local data on breast cancer and mammography practices in northwestern Pennsylvania.

The use of local data on cancer incidence and mortality and on risk-related behaviors to help communities set priorities and guide program planning is an important facet of the National Cancer Institute's Program, "Data-Based Intervention Research for Public Health Agencies." As a participant in this program, the Pennsylvania Department of Health has developed a "breast cancer profile" for a seven-county, predominantly rural region of northwestern Pennsylvania. Community hospitals in the area are collaborating with the health department to develop interventions to enhance screening mammography. The availability of the profiles allowed hospitals to compare local breast cancer risk and screening activities with those of the State and nation, to target interventions, and to establish a baseline to measure changes over time. The data generated great interest among health professionals in northwestern Pennsylvania because, contrary to their expectations, the region was quite similar to the State and nation. While the proportion of women ages 40 and older who had ever had a mammogram was relatively high (66 percent), the proportion with more than one mammogram was considerably lower (43 percent), suggesting that hospitals focus on promoting regular mammography. Although it is feasible to develop data-based interventions for local areas, the effort is not trivial. State and national agencies must cooperate to ensure comparability of data collection and reports so that comparisons of local, State, and national data can be produced routinely.

A perception experiment with time-critical graphics animation on the World-Wide Web.

The World-Wide Web offers a potentially interesting tool to collect data from a large and heterogeneous audience. While questionnaires have become rather common on the Internet, its potential reaches far beyond text processing. In principle, it is possible not only to perform interactive, dynamic experiments on the Web, but also to include graphical animation and time-critical responses, such as reaction times. We implemented a visual motion extrapolation task on the Web using the programming language Java, which can be interpreted by standard Web browsers such as Netscape or Internet Explorer. The data collected with this method turned out to be reliable and differed little from data obtained in a controlled laboratory setting, with the exception of conditions with fixation instruction. Thus, the Web can, generally speaking, be used for data collection of large sample sizes. The strengths and weaknesses of dynamic visual simulation experiments on the Internet are discussed.

Faculty research productivity and organizational structure in schools of nursing.

The purpose of this study was to identify the relationship between faculty research productivity and organizational structure in schools of nursing. The need for nursing research has been widely recognized by members of the nursing profession, yet comparatively few engage in conducting research. Although contextual variables have been investigated that facilitate or inhibit nursing research, the relationship between organizational structure and nursing research productivity has not been examined. This problem was examined within the context of the Entrepreneurial Theory of Formal Organizations. A survey methodology was used for data collection. Data on individual faculty research productivity and organizational structure in the school of nursing were obtained through the use of a questionnaire. A random sample of 300 faculty teaching in 60 master's and doctoral nursing schools in the United States was used. The instruments for data collection were Wakefield-Fisher's Adapted Scholarly Productivity Index and Hall's Organizational Inventory. The data were analyzed using Pearson Product-Moment Correlation Coefficients and multiple correlation/regression techniques. The overall relationship between faculty research productivity and organizational structure in schools of nursing was not significant at the .002 level of confidence. Although statistically significant relationships were not identified, scholarly research productivity and its subscale prepublication and research activities tended to vary positively with procedural specifications in a highly bureaucratic organizational structure. Further research may focus on identification of structural variables that support highly productive nurse researchers.

Relating outcomes to processes of care: the Maryland Hospital Association's Quality Indicator Project (QI Project).

BACKGROUND: The Maryland Hospital Association's Quality Indicator Project (QI Project) is a program of indicator development and application that has grown from 7 hospitals in 1987 to more than 700 hospitals today. METHODOLOGY: Expert panels help to create sets of indicators that describe events involved in a specific sequence of patient care. Each hospital collects data elements for the 21 indicators on a quarterly basis using specifically designed data-collection software. Indicator data are adjusted for case complexity, risk of adverse outcomes, and patient group characteristics. A report is developed that states the rate of occurrence of each indicator and how the hospital's indicator rate compares to other hospitals in the database. Hospitals then use this information to determine if specific processes in their delivery of care yield results that deviate from those of other hospitals. The QI Project promotes regional sharing of information about specific hospital initiatives that might benefit other participants. It also provides a model to use in interpreting what the indicator data reveal about hospital performance. OPERATIONAL ISSUES: QI Project is testing process indicators for patient-level and service-level data to supplement current aggregate-level trend and profile analysis. Indicator data are shared solely with participating systems, but changes in the confidentiality policy are being studied. Reliability assessment surveys are periodically conducted. EXAMPLES: Case studies portray improvement of processes prompted by indicator data for unscheduled admission following ambulatory surgery, for surgical wound infections, and for reducing emergency room waiting times. CONCLUSIONS: The chief contribution of the QI Project and similar projects may not be that they identify all issues of quality, but rather that they may help develop a generation of hospital professionals who will be better able to quantify, evaluate, and improve health care quality.

The effect of early initiation of breast feeding on the amount of vaginal blood loss during the fourth stage of labor.

Post partum hemorrhage is a major problem that jeopardizes maternal health. Its prevention can save mothers' life postnatal, through early initiation of breast-feeding. So, the study aimed to explore the effect of early initiation of breast feeding on the amount of vaginal blood loss during the fourth stage of labor. A convenient sample of one hundred primiparae was selected from the delivery unit & post partum unit of El-Shatby Maternity University Hospital in Alexandria. The study subjects were divided equally into experimental group (early breast feeding group) and control group (late breast feeding group). Two tools were developed and used for data collection. A specially designed interview questionnaire was used during early first stage of labor to collect data about general characteristics of the study subjects. An observational checklist was used during the fourth stage of labor to collect data about uterine characteristics, number of feeds and the amount of blood loss. The early breast-feeding group started feeding immediately after placental delivery, while late breast feeding group started breast- feeding after the first two hours postnatally. The amounts of blood loss for both groups were calculated. The findings of the study revealed that early initiation & increased frequency of breast-feeding could decrease the amount of blood loss during the fourth stage of labor. Therefore, maternity and pediatric nurses have to encourage mothers to start breast-feeding early. They have to explain how breast-feeding is beneficial for both mother and child.

Polysaccharide vaccines for preventing serogroup A meningococcal meningitis.

BACKGROUND: Controlled trials over two decades ago showed that the polysaccharide vaccine prevented meningococcal meningitis. Subsequent observational studies suggested variations in the level and duration of protection, particularly among young children. OBJECTIVES: To determine the effect of polysaccharide serogroup A vaccine for preventing serogroup A meningococcal meningitis. SEARCH STRATEGY: MEDLINE and the Cochrane Controlled Trials Register. SELECTION CRITERIA: Randomised and other prospective controlled trials. DATA COLLECTION AND ANALYSIS: One reviewer collected data and assessed the methodologic quality of the trials. Data were pooled using the Exact method to assess vaccine efficacy at one, two and three years post-vaccination. MAIN RESULTS: The protective effect within the first year was consistent across all eight trials, including one with participants exclusively under six years of age (in Finland); overall vaccine efficacy was 95% (Exact 95% CI 87%, 99%). The Finnish trial lacked statistical power to assess the effect of a booster dose given to children less than 18 months old. In the three other trials that included children less than six years old (one in Sudan and two in Nigeria), none of the vaccinated children developed meningitis, but the statistical significance of this finding was undetermined. Protection extended into the second (in two studies) and third (in one study) years after vaccination, but these results were also not statistically significant. REVIEWER'S CONCLUSIONS: When compared with current recommendations, the methodological quality and relative incompleteness of the published reports could arguably render the trials invalid for this review. However, it was unlikely that the results of the trials in such diverse settings would have been biased towards a strong and consistent protective effect. Immunogenicity trials were not included in this review. Stage two of the review will assess the vaccine effect from observational studies.

Professional nurses' perception of nursing mentally ill people in a general hospital setting.

The aim of this study was to explore professional nurses' perception of nursing mentally ill patients in a tertiary hospital in Durban. An explorative, qualitative, descriptive and contextual design was followed as the basis for conducting the study. The above-mentioned research design was achieved through field work conducted in an urban-based general hospital. A sample of 12 professional nurses was selected from a population of 800 professional nurses employed in this setting using a purposive sampling technique. This sample size was determined by saturation of data as reflected in repeating themes. Both individual phenomenological semistructured interviews and field notes in the form of observations were used as methods of data collection. The field work was conducted without any preset theoretical framework of reference by using bracketing and intuiting. During interviews, participants were asked only one research question, namely: 'How do you perceive nursing mentally ill patients in your unit or ward?' Communication skills were employed to encourage participants to verbalize their perception of nursing mentally ill patients in a general hospital setting. A tape recorder was used to collect data and the data was transcribed verbatim. Data collected was analysed following the descriptive method of Giorgi (1986). Coding was carried out by the researcher and an independent expert who is a psychiatric nursing specialist and a qualitative research expert. After data analysis, the results were reflected within universal categories of the Nursing for the Whole Person Theory in order to give them structure. The four themes that emerged from the findings are: perception of self, perception of a patient, perception of feelings that hinder nursing the mentally ill, and perception of the environment. The measures for ensuring trustworthiness proposed by Guba (Lincoln Y.S. & Guba E.G. (1985) Naturalistic Inquiry. Sage, Beverly Hills) were used as the basis for ensuring reliable and valid findings. The perception of nursing mentally ill people within a general hospital setting was negative and affected the intellectual and the affective component of the nurses' psychological functioning within their internal environment. It was recommended that nurses' knowledge and skills should be increased and that they should be given emotional support in terms of counselling.

Validation studies of drug exposures in pregnant women.

The aim of these studies was to check the quality of data collection concerning drug use during pregnancy in the Hungarian Case-Control Surveillance of Congenital Abnormalities from four different aspects. (a) The parents of non-respondent cases were visited at home to collect data, but the Ethics Committee did not allow collection of comparable data from non-respondent control women. Thus only 200 selected non-respondent controls were visited at home and questioned about drug use as part of a validation study. There was no difference in the distribution and occurrence of frequently used drugs between the respondent and non-respondent control groups. (b) Data collection was compared between the usual method of the Case-Control Surveillance and personal interview in case with congenital limb deficiencies. In general, the two methods produced similar results with respect to drug use, but the personal interview revealed a higher use of unintended contraceptive pills while the use of antenatal care logbooks in the Case-Control Surveillance showed a higher use of drugs to prevent threatened abortion and preterm delivery. (c) A check of source and completeness of drug exposure showed that about one-quarter of the drugs used during pregnancy were not recorded in the Case-Control Surveillance, and the proportion of lack of recall was about 23%. A small group of women (2.4%) did not use prescribed drugs due to the suspected teratogenic risk. (d) The teratogenic labelling of drugs deters pregnant patients from the use of prescribed drugs, or at least shortens the duration of drug intake. Thus the evaluation of drug use on the basis of medically recorded prescribed drugs and/or usual recommendations produces a bias thus it is necessary to complete it with information from the patients.

The role of structured observational research in health care.

Structured observational research involves monitoring of healthcare domains by experts to collect data on errors, adverse events, near misses, team performance, and organisational culture. This paper describes some of the results of structured observational studies carried out in health care. It evaluates the strengths, weaknesses, and future challenges facing observational researchers by drawing lessons from the human factors and neonatal arterial switch operation (ASO) study in which two human factors specialists observed paediatric cardiac surgical procedures in 16 UK centres. Lessons learned from the ASO study are germane to other research teams embarking on studies that involve observational data collection. Future research needs robust observer training, clear measurable criteria to assess each researcher's domain knowledge, and observational competence. Measures of inter-rater reliability are needed where two or more observers participate in data collection. While it is important to understand the factors that lead to error and excellence among healthcare teams, it is also necessary to understand the characteristics of a good observer and the key types of error that can occur during structured observational studies like the human factors and ASO project.

Pelvic floor muscle training with biofeedback and bladder training in elderly women: a feasibility study.

OBJECTIVE: It is generally assumed that interventions used to treat urinary incontinence (UI) in young women could simply be applied to older competent and motivated women, but these assumptions have not been formally tested. The purpose of this study was to determine the feasibility of using physical therapies to treat UI in older women. DESIGN: Twelve-week time series. SETTINGS AND SUBJECTS: We recruited women older than 75 years with UI from an outpatient urology clinic and a waiting list for incontinence surgery. METHODS: After a baseline evaluation, the women collected data on their incontinence symptoms and bladder habits for 3 weeks using the 72-hour voiding diary and the 24-hour pad test. They then received 6 physical therapy treatments consisting of a combination of bladder training and pelvic floor muscle training assisted with biofeedback for 6 weeks. This was followed by another 3-week period of data collection and a final evaluation. RESULTS: Ten women participated in the study; 7 completed it. They were all comfortable with the treatment. They complied with the study demands in terms of attendance at treatment session (100%), data collection (96%), and completion of exercises at home (82%). The authors observed a decrease in the number of incontinent and urgency episodes. CONCLUSION: This preliminary study demonstrates that some women older than 75 years are good candidates to undertake physical therapies for UI and follow study demands. Random controlled studies that include this population will provide evidence regarding the effectiveness of these therapies.
