Ingår i: User Interfaces. ; , s. 23-

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- User profile is a popular term widely employed during product design processes by industrial companies. Such a profile is normally intended to represent real users of a product. The ultimate purpose of a user profile is actually to help designers to recognize or learn about the real user by presenting them with a description of a real user’s attributes, for instance; the user’s gender, age, educational level, attitude, technical needs and skill level. The aim of this chapter is to provide information on the current knowledge and research about user profile issues, as well as to emphasize the importance of considering these issues in interface design. In this chapter, we mainly focus on how users’ difference in expertise affects their performance or activity in various interaction contexts. Considering the complex interaction situations in practice, novice and expert users’ interactions with medical user interfaces of different technical complexity will be analyzed as examples: one focuses on novice and expert users’ difference when interacting with simple medical interfaces, and the other focuses on differences when interacting with complex medical interfaces. Four issues will be analyzed and discussed: (1) how novice and expert users differ in terms of performance during the interaction; (2) how novice and expert users differ in the perspective of cognitive mental models during the interaction; (3) how novice and expert users should be defined in practice; and (4) what are the main differences between novice and expert users’ implications for interface design. Besides describing the effect of users’ expertise difference during the interface design process, we will also pinpoint some potential problems for the research on interface design, as well as some future challenges that academic researchers and industrial engineers should face in practice.

- Hip fractures are a major cause of hospital stay among the elderly, and result in increased disability and mortality. In this study from 1 April 2003 to 31 March 2004, the influence of optimised treatment of hip fracture on time to operation, length of hospital stay, reoperations and mortality within 1 year were investigated. Comparisons were made between the first 210 patients in the period and the last 210 patients, who followed the new clinical pathway introduced at the University Hospital in Lund, Sweden. Early surgery, within 24h, was not associated with reduced mortality, but was significantly associated with reduced length of stay (p<0.001). Significantly more cases of osteosynthesis for femoral neck fracture were reoperated compared with all other types of surgery (p<0.001) when reoperations with extraction of the hook pins in healed fractures were excluded. Mortality was significantly higher among men than women at 4 (p=0.025) and 12 (p=0.001) months after fracture and among medically fit patients with administrative delay to surgery compared with patients with no delay (p<0.001).

- OBJECTIVE: To evaluate attitudes of Europeans regarding end-of-life decisions. DESIGN AND SETTING: Responses to a questionnaire by physicians and nurses working in ICUs, patients who survived ICU, and families of ICU patients in six European countries were compared for attitudes regarding quality and value of life, ICU treatments, active euthanasia, and place of treatment. MEASUREMENTS AND RESULTS: Questionnaires were distributed to 4,389 individuals and completed by 1,899 (43%). Physicians (88%) and nurses (87%) found quality of life more important and value of life less important in their decisions for themselves than patients (51%) and families (63%). If diagnosed with a terminal illness, health professionals wanted fewer ICU admissions, uses of CPR, and ventilators (21%, 8%, 10%, respectively) than patients and families (58%, 49%, 44%, respectively). More physicians (79%) and nurses (61%) than patients (58%) and families (48%) preferred being home or in a hospice if they had a terminal illness with only a short time to live. CONCLUSIONS: Quality of life was more important for physicians and nurses than patients and families. More medical professionals want fewer ICU treatments and prefer being home or in a hospice for a terminal illness than patients and families.

- Patients' memories of frightening ICU experiences may be a threat to later psychological recovery. The purpose of the study is to describe ICU patients' recall of their emotional reactions, from falling critically ill to hospital discharge; this at 3 and 12 months following discharge from the ICU. The study is qualitative and concerns eight ICU patients ventilated for more than 72h. The participants were interviewed twice and the data were subjected to qualitative content analysis. It emerged that the memories of emotions during the trajectory of critical illness were extensive, detailed and strong, and that unpleasant emotions were clearly stable over time. At 12 months as compared with 3 months, the unpleasant emotions were less intense and had less prominent; furthermore the ICU care was more greatly associated with a sense of security, and there was greater recall of caring doctors and nurses (though not of their names) as well as next of kin. CONCLUSIONS: The study generated knowledge not previously described about how ICU patients' recollection of their emotions during the trajectory of critical illness changes over time. This has implications regarding future study of patients' ICU memories and regarding patients' need for support in coping with such memories.

Intrathecal catheters with subcutaneous port systems in patients with severe cancer-related pain managed out of hospital : the risk of infection
- 2006
-
Ingår i: Journal of Pain and Symptom Management. - : Elsevier. - 0885-3924 .- 1873-6513. ; 31:6, s. 568-572

Tidskriftsartikel (refereegranskat)abstract
- Intrathecal catheters have been used for many years to treat severe pain resistant to conventional treatment modalities. Previous studies have found a rate of serious infection of 2%-3% using these catheters in home situations. However, many authors used prophylactic antibiotics routinely in this group of patients, which are both costly and associated with a risk of developing antibiotic resistance. We were interested in studying whether improved hygiene during insertion and care of these catheters in the hospice or home environment would reduce the incidence of catheter-related infections. The results show that prophylactic antibiotic is not necessary, but a careful handling of the system with aseptic technique is important. The infections we registered appeared more than 2 weeks after insertion of the catheters. We now use this method routinely when inserting an intrathecal catheter with a subcutaneous port.

- Objective. To study the kinetics of lipid micro-emboli during cardiac surgery. Design. Eleven pigs were studied. Seven of these were put on extracorporeal circulation. A shed blood phantom consisted of blood, saline and radioactive triolein was added to the circuit. Both venous and arterial blood samples were taken at short intervals. Four animals were used to study renal kinetics without extracorporeal circulation. The same kind of shed blood phantom was infused into the ascending aorta. Samples were taken from the renal artery and vein. All samples were analyzed for radioactivity by scintillation counting. Results. A median 130-fold increase in radioactivity was seen in the blood and was quickly eliminated. Systemic first-pass wedging was found to be 62%. The first-pass elimination in the kidney was 77%. No radioactivity was found in urine. Conclusions. This study shows that the turnover of lipid micro-emboli is fast, and that the majority of the emboli are trapped on their first passage through the capillary system. No evidence was found of a renal excretion of these lipid emboli.

- International and national guidelines on requirements for performing lung recruitment manoeuvres are lacking. This paper presents a nationwide descriptive survey of the occurrence of and conditions for lung recruitment in adult patients treated with mechanical ventilation in intensive care units (ICUs) in Sweden. All ICUs except neurological, cardiac, paediatric and neonatal ICUs were invited (N=73); of these, 60 ICUs participated in the study (82%). The main outcome measures were prevalence of lung recruitment, whether ICU nurses and/or physicians carried out lung recruitment, requirements for nurses to perform lung recruitment and the existence of local guidelines. Lung recruitment was performed at 92% of the ICUs. Only physicians performed lung recruitment at 27 ICUs (49%), and in 28 units (51%) both physicians and nurses performed this treatment. Lung recruitment was performed more often in units where both physicians and nurses performed lung recruitment than in units where only physicians performed the manoeuvres (46% vs. 12%, p=0.03). Further, local guidelines on lung recruitment manoeuvres were more common in units where both physicians and nurses performed this treatment (71% vs. 41%, p=0.02). The results suggest that recommendations of repeated and prompt lung recruitment manoeuvres are better met if nurses, along with physicians, perform lung recruitment.

- Case report.To present an unusual traumatic neurologic pathology caused by gunshot injury.Spine unit of Department of Trauma and Orthopaedic Surgery, University Medical School, Charité - Campus Benjamin Franklin, Berlin, Germany.A 35-year-old male sustained a gunshot injury from a machine gun. The projectile caused a fracture of the left pedicle of Th10. The spinal cord was indirectly damaged by cavitation that caused a Brown-Séquard syndrome (BSS). After a microscopically assisted posterior revision at T9/10 with removal of bullet and bone fragments from the spinal canal and debridement of the bullet cavity via extended fenestrectomy the patient gained his motor function back. The sensory deficit remained unchanged.BSS can be caused by bullet-related injury of the spinal canal with no direct damage of neural structures. The initial treatment is always based on the total injury pattern. Possible spinal cord injuries are only clarified after restitution of vital functions. Decompression of neural structures in shotgun injury is indicated in incomplete paraplegia, injury of intra-abdominal hollow organs or high velocity bullet wounds. Through debridement and decompression of neural structures and chronic damage caused by foreign body granulomas can be prevented. Secondary destabilization of the spine should be avoided.

Forskningsöversikt (refereegranskat)abstract
- Posttraumatic anemia in multiply injured patients is caused by hemorrhage, reduced red blood cell survival, and impaired erythropoiesis. Trauma-induced hyperinflammation causes impaired bone-marrow function by means of blunted erythropoietin (EPO) response, reduced iron availability, suppression and egress of erythroid progenitor cells. To treat posttraumatic anemia in severely injured patients, symptomatic therapy by blood transfusion is not sufficient. Furthermore, EPO, iron, and the use of red cell substitutes should be considered. The posttraumatic systemic inflammatory response syndrome (SIRS) induces posttraumatic anemia. Thus, a worsening of SIRS by a "second-hit" through blood transfusion ought to be avoided.
