Considering the importance of user profiles in interface design
- 2009

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.

- The aim of this study was to describe nurses' conceptions of decision making with regard to life-sustaining treatment for dialysis patients. Semistructured interviews were conducted with 13 nurses caring for such patients at three hospitals. The interview material was subjected to qualitative content analysis. The nurses saw decision making as being characterized by uncertainty and by lack of communication and collaboration among all concerned. They described different ways of handling decision making, as well as insufficiency of physician-nurse collaboration, lack of confidence in physicians, hindrances to patient participation, and ambivalence about the role of patients' next of kin. Future research should test models for facilitating communication and decision making so that decisions will emerge from collaboration of all concerned. Nurses' role in decision making also needs to be discussed.

- There is a lack of knowledge regarding how critically ill patients recall of the ICU and their life-threatening condition changes over time. The purpose of this study is to describe critically ill and ventilator-treated patients' recollections of both factual events and unreal experiences at 3 and 12 months following discharge from the ICU. The study is qualitative and encompasses nine critically ill ICU patients, ventilator-treated for more than 72 h. The participants were interviewed twice, at 3 and 12 months after their discharge from the ICU. The interviews were analysed using qualitative content analysis. The patients in this study reported unreal experiences, memory confusion and/or disturbances before admittance to the ICU and before their respirator treatment. Their "unreal experiences" were far clearer than their memories of factual occurrences. Patients' fragmentary memories of factual events and their recall of unreal experiences were practically unchanged after 12 month. Their unreal experiences could still be recalled and related after 12 months, but not with the same expression and feeling as earlier (3 months). The unreal experiences were not - after 12 months - their initial recollections, as they had been after 3 months. Conclusions: Patients' recollections of both factual events and unreal experiences show very little variation between 3 and 12 months. The stability of long-term memory after 12 months shows that the recollection of their experiences had been both traumatic and emotionally charged. This study shows that critically ill patients were affected by cognitive disturbances and/or disturbed memory before their arrival at the ICU. This result indicates the need of ICU follow-up clinics.

- 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).

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: National guidelines recommend activation of the emergency medical service by patients who have symptoms of acute coronary syndrome (ACS). In spite of this, only 50% to 60% of persons with myocardial infarction initiate care by using the emergency medical service. The aim of this study was to define factors influencing the use of ambulance in ACS. METHODS: The method used in this study was a national survey comprising intensive cardiac care units at 11 hospitals in Sweden; 1,939 patients with diagnosed ACS and symptom onset outside the hospital completed a questionnaire a few days after admission. RESULTS: Half of the patients went to the hospital by ambulance. Factors associated with ambulance use were knowledge of the importance of quickly seeking medical care and calling for an ambulance when having chest pain (odds ratio [OR] 3.61, 95% CI 2.43-5.45), abrupt onset of pain reaching maximum intensity within minutes (OR 2.08, 1.62-2.69), nausea or cold sweat (OR 2.02, 1.54-2.65), vertigo or near syncope (OR 1.63, 1.21-2.20), ST-elevation ACS (OR 1.58, 1.21-2.06), increasing age (per year) (OR 1.03, 1.02-1.04), previous history of heart failure (OR 2.48, 1.47-4.26), and distance to the hospital of >5 km (OR 2.0, 1.55-2.59). Those who did not call for an ambulance thought self-transport would be faster or did not believe they were sick enough. CONCLUSIONS: Symptoms, patient characteristics, ACS characteristics, and perceptions and knowledge were all associated with ambulance use in ACS. The fact that knowledge increases ambulance use and the need for behavioral change pose a challenge for health-care professionals.

- 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.

- 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.

- Objective To identify obstacles to organ donation in Swedish intensive care units.Design A survey exploring attitudes and experiences of organ donation activities was sent to half of all anaesthetists and all neurosurgeons in Sweden (n = 644). Total response rate was 67%; 69% from the anaesthetists and 54% from the neurosurgeons.Results Neurosurgeons had more experiences of caring for potential donors and requesting donation than anaesthetists. Twenty-seven percent of the anaesthetists were not confident with clinical neurological criteria for brain incarceration. Nine per cent found donation activities solely burdensome, and 14% wanted an external team to take over the donation request. A quarter regarded the request definitely as an extra load on the family, and more than half of the respondents had refrained from asking in emotionally strained situations. Forty-nine per cent had a neutral approach to relatives when requesting donation while 38% had a pro-donation approach. Thirty-six per cent terminated ventilator treatment for a potential donor without waiting for total brain infarction. Lack of resources in the ICUs resulted in not identifying a possible donor according to 29% of respondents. Knowing the prior wish of the deceased was regarded as the single most important factor that facilitated the work with organ donation for the intensivists.Conclusions The identified obstacles (neutral approach of donation request, ethical problems concerning the potential donor and the relatives, varying competence in diagnosing total brain infarction, and lack of intensive care bed resources) require tailored efforts in order to increase organ donation. Checking these factors can be used as a quality control when analysing donation activities at hospitals.

Assessment of recovery after day surgery using a modified version of quality of recovery-40
- 2009

Ingår i: Acta Anaesthesiologica Scandinavica. - : Wiley. - 0001-5172 .- 1399-6576. ; 53:5, s. 673-677

Tidskriftsartikel (refereegranskat)abstract
- A recent nationwide survey in Sweden found that day surgery accounts for 43% of all in-hospital procedures.1 Orthopaedic, general, and gynaecological procedures were the most common. About 40% of the day surgery units followed up with telephone calls within 1–2 days, and found pain to be the most common complaint. Quality of recovery had not been systematically evaluated with instruments tested for validity and reliability, and follow-ups beyond 2 days post-operative were not found.Quality of Recovery-40 (QoR-40)2,3 is a 40-item instrument to assess the quality of post-operative recovery. The instrument is divided into five dimensions; emotional state, physical comfort, psychological support, physical independence, and pain. These dimensions represent aspects of good-quality recovery after anaesthesia and surgery. QoR-40 has been used for patients undergoing different surgical procedures and tests for validity and reliability yielded initial support for the instrument. Myles et al.3 concluded that QoR-40 would be a useful outcome measure to assess the impact of changes in health care delivery on quality of care, but anaesthesia and surgery studies have rarely used this approach. Although QoR-40 has not been used exclusively for day surgery patients, some day surgery patients were included when the instrument was developed.2,3 Another study on day surgery patients4 used eight items from QoR-40 relevant to that study. In a systematic review of post-operative recovery outcomes measurements after ambulatory surgery, the QoR-40 was the only instrument that fulfilled the criteria that were set up but was not specifically designed for day surgery and anaesthesia.5 Another systematic review from 2008 also advises to use the QoR-40 in future validation and application studies.6 Day surgery is increasing, and it is important to measure the quality of care and the impact of change. When using an instrument such as QoR-40, each item must be carefully considered for the purpose and context it will be used in, especially when it differs from the original context, both concerning cultural differences between countries and the type of surgical procedure used. Therefore, our study created and used a modified version of the QoR-40 to measure the quality of recovery in day surgery patients. The study aimed to test this modified version in a Swedish context for day surgery patients, to assess the quality of recovery on days 1, 7, and 14 post-operative.
