An evaluation of nursing practice models in the context of the severe acute respiratory syndrome epidemic in Hong Kong: a preliminary study

JOURNAL OF CLINICAL NURSING, Issue 6 2006
Engle Angela Chan PhD
Aim and objective., Like other health-care workers, Hong Kong nurses had their professional knowledge and skills seriously challenged during the SARS outbreak. Could current nursing practices support the care of SARS or SARS-like patients in the future? If not, alternative practices would be needed. Providing a preliminary understanding, this paper compares the conventional with different nursing delivery models in a simulated SARS ward and focuses on nurses' efficiency, infection control practices and views of the two models. Design and methods., This study was conducted in three phases. First, a baseline understanding of nursing practices was achieved through four workflow observations. In an eight-hour day, four research assistants observed nursing activities in the medical and fever wards. These data were used in the second phase to construct two sets of clinical vignettes, pertaining to SARS patient care in both conventional and alternative practice models. These scripts were discussed with nine nurses of various ranks from the hospital under study for their expert validation and input. In the third phase, nurse participants and patient actors enacted the vignettes in a simulated setting. Video-taped observations and four nurse participant interviews were employed. Observational data were analysed through descriptive statistics and independent t -tests. Textual data were coded and categorized for common meanings. Results., Conventional practice from the findings consisted of cubicle and named nurse nursing. While the former reflected modified team and functional nursing, it did not confine patient care within a cubicle as suggested by its name. The latter depicted a modified primary nursing approach in a team, with delegation of care. Preliminary findings concerning infection control and nurse satisfaction revealed that the alternative model had an advantage over the conventional. Relevance to clinical practice., This study findings lay the foundation for clinical trials, which would evaluate the significance of patient-care quality, cost-effectiveness and better human resource management by restructuring current nursing practices.

Multicontextual occupational therapy intervention: a case study of traumatic brain injury

OCCUPATIONAL THERAPY INTERNATIONAL, Issue 1 2001
Belkis Landa-Gonzalez
Abstract Cognitive deficits after a traumatic brain injury can result in significant functional limitations in all areas of daily living. An individual's ability to generalize learning may be limited, thus making it harder to live independently in the community. Assessing a client's metacognitive skills and awareness level may help to establish a baseline understanding about the supervision required and the most suitable living arrangements. This study describes a multicontextual, community re-entry occupational therapy programme directed at awareness training and compensation for cognitive problems in a 34-year-old man with traumatic brain injury. Intervention consisted of metacognitive training, exploration and use of effective processing strategies, task gradations and practice of functional activities in multiple environmental contexts. Strategies such as self-prediction, self-monitoring, role reversal and the use of checklists were used. Results after six months of intervention show improvements in the client's awareness level, enhancement of his occupational function, increased satisfaction with performance and a decrease in the level of attendant care. Additional studies are recommended to validate the findings. Copyright © 2001 Whurr Publishers Ltd. [source]

Men's Sexual Health: Evaluating the Effectiveness of Print- and PDA-based CME

THE JOURNAL OF SEXUAL MEDICINE, Issue 9 2009
Gregory A. Broderick MD
ABSTRACT Introduction., Personal digital assistant (PDA)-based continuing medical education (CME) activities have become widely available. Aims., To evaluate the effectiveness of print- and PDA-based CME materials in erectile dysfunction (ED). Methods., CME materials describing links between ED and comorbid medical conditions, effects of certain lifestyle modifications on ED, and treatment of ED with phosphodiesterase 5 (PDE5) inhibitors were distributed as a print supplement and as electronic modules, viewed with PDAs. We evaluated how effectively these materials improved evidence-based clinical choices, using survey questions about case vignettes and comparing responses of CME participants (N = 85) and matched nonparticipants (N = 94). Main Outcome Measures., Effect size, measuring the difference in evidence-based clinical scores between participants and nonparticipants. Results., CME certificates were awarded to 3,557 participants (459 print, 3,098 PDA). Among survey respondents, significantly more CME participants recognized that ED was associated with greater risk for myocardial infarction (61% participants; 34% nonparticipants; P , 0.001) and was a strong marker for diabetes mellitus (37% participants; 9% nonparticipants; P , 0.001). In contrast, participants and nonparticipants both displayed a good understanding of the relationships of smoking, obesity, and sedentary lifestyle with ED and of using PDE5 inhibitors to treat ED in patients with prostate cancer or benign prostatic hyperplasia; this likely reflects a good baseline understanding of these topics. Participants and nonparticipants each displayed a poor understanding of the recommendations regarding nonarteritic anterior ischemic optic neuropathy and PDE5 inhibitor use. Patient reluctance to discuss sexual concerns was perceived as the most significant barrier to optimal ED management. Conclusions., Given patient reluctance to discuss sexual concerns, future CME activities should focus on educating health-care providers and patients that ED is a risk factor for cardiovascular disease and diabetes. Both print- and PDA-based CME on ED were effective; the large number of lesson completers suggests a trend toward on-demand, self-selected CME is positive. Broderick GA, and Abdolrasulnia M.

Species concepts and floras: what are species for?

BIOLOGICAL JOURNAL OF THE LINNEAN SOCIETY, Issue 1 2008
SANDRA KNAPP
In 1992, in a special paper in the American Journal of Botany, Ernst Mayr attempted to ,prove' the biological species concept (BSC) worked as well in plants as it did in animals by analyzing the flora of the Concord region of northern Massachusetts. He concluded that there were minimal difficulties when applying the BSC for the plants of this particular area, and concluded that botanists were misguided in not accepting the BSC. He suggested that what he called ,typological' thinking was prevalent in the taxonomic community, and that this was a factor in botanical resistance to the BSC. Typology, as defined by Mayr in his 1992 foray into botany, is to a certain extent a straw-man and, by the late 20th Century, no longer a way of thinking in widespread use in the taxonomic community in any organismal group. Here, I examine his analysis in the light of current interest in plant diversity. Species can be characterized as hypotheses about the distribution of variation in nature, subject to test with new data of many kinds. Species concepts like the BSC, although of interest philosophically and to researchers looking at mechanisms of speciation, may actually get in the way of achieving a baseline understanding of the diversity of life on Earth. © 2008 The Linnean Society of London, Biological Journal of the Linnean Society, 2008, 95, 17,25.
