Improving clinical communication: a view from psychology.
(25/618)
Recent research has studied the communication behaviors of clinical hospital workers and observed a tendency for these workers to use communication behaviors that were often inefficient. Workers were observed to favor synchronous forms of communication, such as telephone calls and chance face-to-face meetings with colleagues, even when these channels were not effective. Synchronous communication also contributes to a highly interruptive working environment, increasing the potential for clinical errors to be made. This paper reviews these findings from a cognitive psychological perspective, focusing on current understandings of how human memory functions and on the potential consequences of interruptions on the ability to work effectively. It concludes by discussing possible communication technology interventions that could be introduced to improve the clinical communication environment and suggests directions for future research.

The capability of accident and emergency departments to safely decontaminate victims of chemical incidents.
(26/618)
OBJECTIVES: To evaluate the capability of accident and emergency (A&E) departments in six health regions of England to safely decontaminate casualties exposed to hazardous chemicals. METHODS: In January 1999 a postal questionnaire was sent to the clinical director of all A&E departments in Trent, North and South Thames, South and West, North West and, Anglia and Oxford Health Regions. The questionnaire inquired about characteristics of the department, decontamination facilities and equipment, and staff training. Nonresponders were sent a second questionnaire and contacted by telephone if they failed to respond to the second mailing. RESULTS: 308 of 326 departments identified (94%) returned a questionnaire. There was no significant difference in response rate by region (p = 0.99). Analysis was restricted to 154 major departments seeing more than 20000 new attendances per year. Of these 154 departments, 109 (71%) had a written chemical incident plan but only 55 (36%) maintained a list of nearby industrial chemical sites. Fifty nine departments (38%) stated that members of staff had received training in the management of chemically contaminated casualties in the preceding year. Eighteen departments (12%) possessed the level of personal protective equipment (PPE) recommended for decontamination by the Ambulance Services Association. Ninety six departments (62%) had a designated decontamination room but only seven (7%) of them incorporated all the features generally considered necessary for safe decontamination. Forty one units (27%) had the capability to decontaminate casualties outside of the department either with warm water from a shower attachment or with a mobile decontamination unit. Thirty six departments (23%) had neither a decontamination room nor the ability to decontaminate casualties outside the department. Only 16 units (10%) had both adequate PPE and either a decontamination room or the capability to decontaminate outside the department. CONCLUSIONS: This study has identified deficiencies in the current NHS capability to respond to chemical incidents. To resolve this, nationally recognised standards for decontamination facilities, equipment and training should be formulated, agreed and implemented. (+info)
Hepatitis B surface antigen (HBsAg) infection in a hemodialysis unit. II. Factors affecting host immune response to HBsAg.
(27/618)
Serum from 86 hemodialysis patients, 105 healthy hospital staff "at risk" and 160 regular hospital staff was screened for hepatitis B surface antigen (HBsAg) and antibody (anti-HBs). The combined prevalence of HBsAg and anti-HBs was higher in the staff of the artificial kidney unit (57.7%) than in the hemodialysis patients (33.7%). The healthy subjects with HBsAg infection responded significantly more often by producing anti-HBs compared with the hemodialysis patients. Twelve of 29 (41.4%) hemodialysis patients with HBsAg infection produced anti-HBs, while 17 (58.6%) remained positive for HBsAg. This differential response could not be attributed to age, sex, time spent undergoing hemodialysis, delayed cutaneous reactivity or response to phytohemagglutinin (PHA) or pokeweed mitogen (PWM). However, a much larger proportion of patients with HBsAg than with anti-HBs had previously received blood transfusions (88.2% v. 33.3%). Our results indicate that development of the chronic HBsAg carrier state or production of anti-HBs in uremic patients may be influenced by the route of immunization or the dose of antigen, or both. Although uremic patients maintain normal in vitro response to PHA and PWM, they may have depressed immunity in vivo because of a decreased total number of T-lymphocytes. (+info)
A National Institute for Occupational Safety and Health Alert sent to hospitals and the intentions of hospital decision makers to advocate for latex allergy control measures.
(28/618)
This study evaluated a National Institute for Occupational Safety and Health (NIOSH), Centers for Disease Control and Prevention, Alert concerning the risk and prevention of latex allergy among health care workers. It has been estimated that 8-12% of health care workers are sensitized to latex. NIOSH Alerts are publications that are intended to educate stakeholders about risks in the workplace; this Alert contained four recommendations for administrative control measures that hospital decision makers could adopt to reduce the risk of latex allergy to employees. The Alert was mailed to a random selection of Directors of Infection Control and Directors of Nursing in hospitals in the US. A random sample of these targeted recipients and a control group were surveyed by telephone (N = 298). Although nearly all of the respondents were concerned about latex allergy (96%), those reporting having seen the Alert were significantly more likely to report an intention to advocate for one or more of the control measures.

Multiple perspectives on physician order entry.
(29/618)
OBJECTIVE: Describe the complex interplay of perspectives of physicians, administrators, and information technology staff regarding computerized physician order entry (POE) in hospitals. METHODS: Linstone's Multiple Perspectives Model provided a framework for organizing the results of a qualitative study done at four sites. Data from observation, focus groups, and formal and informal interviews were analyzed by four researchers using a grounded approach. RESULTS: It is not a simple matter of physicians hating POE and others loving it. The issues involved are both complex and emotional. All groups see both positive and negative aspects of POE. CONCLUSION: The Multiple Perspectives Model was useful for organizing a description to aid in understanding all points of view. It is imperative that those implementing POE understand all views and plan implementation strategies accordingly. (+info)
A randomised prospective study to evaluate a rapid HIV-antibody assay in the management of cases of percutaneous exposure amongst health care workers.
(30/618)
A rapid start of post-exposure prophylaxis with an antiretroviral regime is recommended after percutaneous exposure to blood from an HIV-positive source. Since the HIV-antibody status of the source is usually not known at the time of injury, antiretroviral treatment is started pending the results of HIV testing of the source. A randomised prospective study was designed to compare the use of a rapid-screening assay in the management of cases of percutaneous exposure with the conventional procedure. Prior to the comparative study, the accuracy of a rapid-screening assay performed by non-laboratory trained personnel was evaluated. 123 blinded HIV-positive and HIV-negative samples were correctly identified. In a randomised comparison with the conventional procedure, the application of the rapid-screening assay resulted in a significant reduction of psychological stress, drug use and cost. The estimated net benefit per case was CHF 93.-(62 US$). This study strongly supports the use of the rapid-screening assay in the management of post-exposure prophylaxis for HIV after percutaneous exposure in health care workers. (+info)
Prevalance of antibody to hepatitis B surface antigen in various populations.
(31/618)
Sera from individuals with different degrees of exposure to the agent of hepatitis B were tested for antibodies to hepatitis B surface antigen (anti-HB-s) by passive hemagglutination and for hepatitis B surface antigen (HB-s Ag) by radioimmunoassay and immunoelectroosmophoresis. In a plasma fractionation plant, anti-HB-s was detected in 82 percent of workers processing human plasma and 3.3 percent were healthy carriers of the antigen. Fifty-six percent of the workers having only casual contact with plasma processing exhibited anti-HB-s and 24 percent of workers with no contact had anti-HB-s, yet HB-s Ag was not found in either of these two groups of workers. A similar correlation was shown in hospital personnel; 31 percent of employees with direct contact to serum specimens and only 8 percent without direct contact had anti-HB-s. The frequency of HB-s Ag (0.8 percent in patients with disorders not involving the liver; 49.8 percent in patients tentatively diagnosed as viral hepatitis) and anti-HB-s (14.5 percent to 28.5 percent, respectively) in selected groups of hospitalized patients varied greatly. In 508 paid blood donors, anti-HB-s was present in 19.9 percent, whereas it was present in only 6.6 percent of 1,146 volunteer donors. These data demonstrate a correlation between frequency of exposure to human blood or blood products and the prevalence of anti-HB-s. (+info)
A rural virtual health sciences library project: research findings with implications for next generation library services.
(32/618)
PURPOSE: The Shared Hospital Electronic Library of Southern Indiana (SHELSI) research project was designed to determine whether access to a virtual health sciences library and training in its use would support medical decision making in rural southern Indiana and achieve the same level of impact seen by targeted information services provided by health sciences librarians in urban hospitals. METHODS: Based on the results of a needs assessment, a virtual medical library was created; various levels of training were provided. Virtual library users were asked to complete a Likert-type survey, which included questions on intent of use and impact of use. At the conclusion of the project period, structured interviews were conducted. RESULTS: Impact of the virtual health sciences library showed a strong correlation with the impact of information provided by health sciences librarians. Both interventions resulted in avoidance of adverse health events. Data collected from the structured interviews confirmed the perceived value of the virtual library. CONCLUSION: While librarians continue to hold a strong position in supporting information access for health care providers, their roles in the information age must begin to move away from providing information toward selecting and organizing knowledge resources and instruction in their use.
