Hospital doctors' assessment of baseline spirometry.
(17/1663)
Baseline spirometry is useful in diagnosing and managing pulmonary disease. In a questionnaire survey of 100 hospital doctors in two hospitals in the Mersey region, their views and ability to interpret baseline spirometry was assessed. Of the 70 doctors who responded, 65% felt they could accurately interpret baseline spirometry. However, only 12% accurately interpreted all five vitalographs in the questionnaire. The majority (72%) felt they had not had adequate teaching in interpretation of spirometry, and 63% would prefer a report from a respiratory technician. These result suggest that improvement needs to be made in interpretation of baseline spirometry. (+info)
Resuscitation from out-of-hospital cardiac arrest: is survival dependent on who is available at the scene?
(18/1663)
OBJECTIVE: To determine whether survival from out-of-hospital cardiac arrest is influenced by the on-scene availability of different grades of ambulance personnel and other health professionals. DESIGN: Population based, retrospective, observational study. SETTING: County of Nottinghamshire with a population of one million. SUBJECTS: All 2094 patients who had resuscitation attempted by Nottinghamshire Ambulance Service crew from 1991 to 1994; study of 1547 patients whose arrest were of cardiac aetiology. MAIN OUTCOME MEASURES: Survival to hospital admission and survival to hospital discharge. RESULTS: Overall survival from out-of-hospital cardiac arrest remains poor: 221 patients (14.3%) survived to reach hospital alive and only 94 (6.1%) survived to be discharged from hospital. Multivariate logistic regression analysis showed that the chances of those resuscitated by technician crew reaching hospital alive were poor but were greater when paramedic crew were either called to assist technicians or dealt with the arrest themselves (odds ratio 6.9 (95% confidence interval 3.92 to 26.61)). Compared to technician crew, survival to hospital discharge was only significantly improved with paramedic crew (3.55 (1.62 to 7.79)) and further improved when paramedics were assisted by either a health professional (9.91 (3.12 to 26.61)) or a medical practitioner (20.88 (6.72 to 64.94)). CONCLUSIONS: Survival from out-of-hospital cardiac arrest remains poor despite attendance at the scene of the arrest by ambulance crew and other health professionals. Patients resuscitated by a paramedic from out-of-hospital cardiac arrest caused by cardiac disease were more likely to survive to hospital discharge than when resuscitation was provided by an ambulance technician. Resuscitation by a paramedic assisted by a medical practitioner offers a patient the best chances of surviving the event. (+info)
A pilot study of community-based training of hospital obstetric senior house officers.
(19/1663)
Most senior house officer (SHOs) posts have little relevance to general practice. This problem was addressed in a pilot community teaching placement, of up to one session per week over four to six months that was set up to learn community-based obstetrics from primary health care teams. The nine participating SHOs were interviewed; qualitative analysis revealed seven themes that were important to the SHOs that should help guide further community-based teaching. Such sessional release for improving the practice-based component of vocational training merits evaluation in a larger study. (+info)
Influence of hospital and clinician workload on survival from colorectal cancer: cohort study.
(20/1663)
OBJECTIVE: To determine whether clinician or hospital caseload affects mortality from colorectal cancer. DESIGN: Cohort study of cases ascertained between 1990 and 1994 by a region-wide colorectal cancer register. OUTCOME MEASURES: Mortality within a median follow up period of 54 months after diagnosis. RESULTS: Of the 3217 new patients registered over the period, 1512 (48%) died before 31 December 1996. Strong predictors of survival both in a logistic regression (fixed follow up) and in a Cox's proportional hazards model (variable follow up) were Duke's stage, the degree of tumour differentiation, whether the liver was deemed clear of cancer by the surgeon at operation, and the type of intervention (elective or emergency and curative or palliative intent). In a multilevel model, surgeon's caseload had no significant effect on mortality at 2 years. Hospital workload, however, had a significant impact on survival. The odds ratio for death within 2 years for cases managed in a hospital with a caseload of between 33 and 46 cases per year, 47 and 54 cases per year, and >/=55 cases per year (compared to one with +info)
The importance of a picture archiving and communications system (PACS) manager for large-scale PACS installations.
(21/1663)
Installing a picture archiving and communication system (PACS) is a massive undertaking for any radiology department. Facilities making a successful transition to digital systems are finding that a PACS manager helps guide the way and offers a heightened return on the investment. The PACS manager fills a pivotal role in a multiyear, phased PACS installation. PACS managers navigate a facility through the complex sea of issues surrounding a PACS installation by coordinating the efforts of the vendor, radiology staff, hospital administration, and the information technology group. They are involved in the process from the purchase decision through the design and implementation phases. They can help administrators justify a PACS, purchase and shape the request for proposal (RFP) process before a vendor is even chosen. Once a supplier has been selected, the PACS manager works closely with the vendor and facility staff to determine the best equipment configuration for his or her facility, and makes certain that all deadlines are met during the planning and installation phase. The PACS manager also ensures that the infrastructure and backbone of the facility are ready for installation of the equipment. PACS managers also help the radiology staff gain acceptance of the technology by serving as teachers, troubleshooters, and the primary point-of-contact for all PACS issues. This session will demonstrate the value of a PACS manager, as well as point out ways to determine the manager's responsibilities. By the end of the session, participants will be able to describe the role of a PACS manager as it relates to departmental operation and in partnership with equipment vendors, justify a full-time position for a PACS manager, and identify the qualifications of candidates for the position of PACS manager.

Care and feeding of a staff for filmless radiology.
(22/1663)
Texas Children's Hospital, a definitive care pediatric hospital located in the Texas Medical Center, has been constructing a large-scale picture archival and communications system (PACS) including ultrasound (US), computed tomography (CT), magnetic resonance (MR), and computed radiography (CR). Developing staffing adequate to meet the demands of filmless radiology operations has been a continuous challenge. Overall guidance for the PACS effort is provided by a hospital-level PACS Committee, a department-level PACS Steering Committee, and an Operations Committee. Operational Subcommittees have been formed to address service-specific implementation, such as the Emergency Center Operations Subcommittee. These committees include membership by those affected by the change, as well as those effecting the change. Initially, personnel resources for PACS were provided through additional duties of existing imaging service personnel. As the PACS effort became more complex, full-time positions were created, including a PACS Coordinator, a PACS Analyst, and a Digital Imaging Assistant. Each position requires a job description, qualifications, and personnel development plans that are difficult to anticipate in an evolving PACS implementation. These positions have been augmented by temporary full-time assignments, position reclassifications, and cross-training of other imaging personnel. Imaging personnel are assisted by other hospital personnel from Biomedical Engineering and Information Services. Ultimately, the PACS staff grows to include all those who must operate the PACS equipment in the normal course of their duties. The effectiveness of the PACS staff is limited by their level of their expertise. This report discusses our methods to obtain training from outside our institution and to develop, conduct, and document standardized in-house training. We describe some of the products of this work, including policies and procedures, clinical competency criteria, PACS inservice topics, and an informal PACS newsletter. As the PACS system software and hardware changes, and as our implementation grows, these products must to be revised and training must be repeated. (+info)
The process of converting to a near filmless operation at the University of Utah, Department of Radiology.
(23/1663)
The Department of Radiology at the University of Utah Health Sciences Center has made the transition from a traditional film-based department to a near filmless operation. The University of Utah is a large teaching hospital and the transition from film in an educational facility will be discussed. This transition has had its difficulties and its success is dependent on the support of departmental leadership and hospital administration. We have had more than 100 years of experience with film, and current procedures were efficient given the limitations of the medium. While motivated by the traditional reasons for moving to a picture archival and communications system (PACS), such as film savings, unavailable films, and faster reports, we found the intangibles to be the larger issue, as well as a source for the largest benefits. This report will discuss the implementation process and the affect it had on all areas of the hospital, including its impact on hospital physicians, radiologists, file room personnel, and technologists. Procedure changes to the flow of patients, film, and electronic images will also be described. This process cannot be viewed as a one-time change, but must be viewed as a continuous process as areas of improvement are identified and new and improved technologies are developed. (+info)
Influence of data display formats on physician investigators' decisions to stop clinical trials: prospective trial with repeated measures.
(24/1663)
OBJECTIVE: To examine the effect of the method of data display on physician investigators' decisions to stop hypothetical clinical trials for an unplanned statistical analysis. DESIGN: Prospective, mixed model design with variables between subjects and within subjects (repeated measures). SETTING: Comprehensive cancer centre. PARTICIPANTS: 34 physicians, stratified by academic rank, who were conducting clinical trials. INTERVENTIONS: PARTICIPANTS were shown tables, pie charts, bar graphs, and icon displays containing hypothetical data from a clinical trial and were asked to decide whether to continue the trial or stop for an unplanned statistical analysis. MAIN OUTCOME MEASURE: Percentage of accurate decisions with each type of display. RESULTS: Accuracy of decisions was affected by the type of data display and positive or negative framing of the data. More correct decisions were made with icon displays than with tables, pie charts, and bar graphs (82% v 68%, 56%, and 43%, respectively; P=0.03) and when data were negatively framed rather than positively framed in tables (93% v 47%; P=0.004). CONCLUSIONS: Clinical investigators' decisions can be affected by factors unrelated to the actual data. In the design of clinical trials information systems, careful consideration should be given to the method by which data are framed and displayed in order to reduce the impact of these extraneous factors.
