A comparison of the Nottingham Health Profile and Short Form 36 Health Survey in patients with chronic lower limb ischaemia in a longitudinal perspective

BackgroundDifferent generic quality of life instruments such as the Nottingham Health Profile (NHP) and the Short Form 36 Health Survey (SF-36) have revealed conflicting results in patients with chronic lower limb ischaemia in psychometric attributes in short-term evaluations. The aim of this study was to compare the NHP and the SF-36 regarding internal consistency reliability, validity, responsiveness and suitability as outcome measures in patients with lower limb ischaemia in a longitudinal perspective.Methods48 patients with intermittent claudication and 42 with critical ischaemia were included. Assessment was made before and one year after revascularization using comparable domains of the NHP and the SF-36 questionnaires.ResultsThe SF-36 was less skewed and more homogeneous than the NHP. There was an average convergent validity in three of the five comparable domains one year postoperatively. The SF-36 showed a higher internal consistency except for social functioning one-year postoperatively and was more responsive in detecting changes over time in patients with intermittent claudication. The NHP was more sensitive in discriminating among levels of ischaemia regarding pain and more able to detect changes in the critical ischaemia group.ConclusionBoth SF-36 and NHP have acceptable degrees of reliability for group-level comparisons, convergent and construct validity one year postoperatively. Nevertheless, the SF-36 has superior psychometric properties and was more suitable in patients with intermittent claudication. The NHP however, discriminated better among severity of ischaemia and was more responsive in patients with critical ischaemia.

Risk factors and prevention among patients with hospital-acquired and pre-existing pressure ulcers in an acute care hospital

AIMS AND OBJECTIVES This study aimed to describe and identify risk factors associated with hospital-acquired pressure ulcers among adults in an acute care hospital compared with patients with pre-existing pressure ulcers present on admission. A further aim was to identify the preventive measures performed with both groups respectively. BACKGROUND Pressure ulcers occur most often in older and immobile persons with severe acute illness and neurological deficits. However, few studies have addressed risk factors that are associated with hospital-acquired pressure ulcers compared with patients with pre-existing pressure ulcers. DESIGN A point prevalence study with a cross-sectional survey design was conducted at a Swedish university hospital. METHOD Data on 535 patients were recorded using a modified version of the protocol developed and tested by the European Pressure Ulcer Advisory Panel, including the Braden scale for risk assessment. RESULTS The prevalence of pressure ulcers was 27% (95% confidence interval, 23-31%). Higher age and a total Braden score below 17 were significantly associated with the presence of pressure ulcers. Among individual risk factors higher age, limited activity level and friction and shear while seated or lying down were associated with hospital-acquired pressure ulcers, whereas only higher age and friction and shear were associated with the presence of pressure ulcers in the overall sample. There was an overall sparse use of preventive measures to relieve pressure. CONCLUSION The findings of the present study revealed that pressure ulcers and the insufficient use of preventive measure to relieve pressure is still a problem in acute care settings. A continued focus must be placed on staff training in identifying patients at risk for pressure ulcers development. RELEVANCE TO CLINICAL PRACTICE Increasing the ability to identify patients who are at risk for pressure ulcer development can assist in preventing unnecessary complications and suffering as well as reduce costs.

Malnutrition prevalence and precision in nutritional care differed in relation to hospital volume – a cross-sectional survey

BackgroundTo explore the point prevalence of the risk of malnutrition and the targeting of nutritional interventions in relation to undernutrition risk and hospital volume.MethodsA cross-sectional survey performed in nine hospitals including 2 170 (82.8%) patients that agreed to participate. The hospitals were divided into large, middle, and small sized hospitals. Undernutrition risk and overweight (including obesity) were assessed.ResultsThe point prevalence of moderate/high undernutrition risk was 34%, 26% and 22% in large, middle and small sized hospitals respectively. The corresponding figures for overweight were 38%, 43% and 42%. The targeting of nutritional interventions in relation to moderate/high undernutrition risk was, depending on hospital size, that 7–17% got Protein- and Energy Enriched food (PE-food), 43–54% got oral supplements, 8–22% got artificial nutrition, and 14–20% received eating assistance. Eating assistance was provided to a greater extent and artificial feeding to a lesser extent in small compared to in middle and large sized hospitals.ConclusionThe prevalence of malnutrition risk and the precision in provision of nutritional care differed significantly depending on hospital volume, i.e. case mix. It can be recommended that greater efforts should be taken to increase the use of PE-food and oral supplements for patients with eating problems in order to prevent or treat undernutrition. A great effort needs to be taken in order to also decrease the occurrence of overweight.

Searching for Evidence Regarding Using Preoperative Disinfection Showers to Prevent Surgical Site Infections: A Systematic Review

BACKGROUND Postoperative surgical site infections (SSI) are the third most common health care associated infection. Even though several studies have pointed out the benefits of disinfection showers prior to surgery in order to reduce SSI, it remains unclear how to optimize this disinfection procedure. AIM To find evidence for how many times preoperative disinfection showers should be performed in order to reduce bacterial colonies and minimize the risk of SSI. METHOD A comprehensive literature search of multiple databases published during 1986-2008, supplemented by a manual search of the references in all relevant articles. Protocols were used in quality assessment and the data synthesis is descriptive in a narrative form. RESULTS The 10 studies included had different designs, interventions, and samples, which makes it difficult to compare them. Moreover, the quality of the reviewed studies varied and only four had a high level of evidence. Therefore, the results failed to give an unambiguous answer about the optimal number of preoperative showers, so only assumptions can be made. It is quite obvious, however, that preoperative disinfection showers with chlorhexidine gluconate (CHG) are effective from a microbiological point of view since eight of the reviewed studies showed a sharply reduced skin flora after using CHG. CONCLUSIONS Currently, clear evidence for how many times preoperative disinfection showers should be performed to minimize the risk of SSI is missing. This highlights the need for further research that focuses on the number of preoperative disinfection showers in relation to SSI, in order to obtain optimal effect. Until then, it would be wise to follow previously made recommendation of three to five preoperative showers. Moreover, in order to have the intended effect of preoperative disinfection, it is important that health care professionals have the knowledge to guide patients with information and clear instructions about disinfection shower procedures.

“This is nursing”: Nursing roles as mediated by precepting nurses during clinical practice

In nursing education, it has been argued that professional socialization is facilitated by clinical experiences where students work together with precepting nurses. However, few studies found have focused on how nurses think and act as preceptors, hence providing a base for professional socialization to occur. Therefore; this study aimed to describe how preceptors mediated nursing as a profession to undergraduate nursing students during clinical practice. This was an ethnographic study guided by symbolic interactionism. A purposeful sampling of 13 precepting nurses was observed during the field work period. In addition, 16 staff nurses, purposively selected, and experienced in precepting, participated in focus group interviews. All text from field notes and interviews were read as a whole and analyzed following the ethnographic approach. Findings illustrated how nursing was mediated as the medical-technical, the administrative, and the caring role. Preceptors aimed for professionalism in their students by teaching the students to reflect on what they can do independently as nurses. Preceptors strived to verbalise their practical knowledge to make theory explicit and contextualize to student nurses. This knowledge can guide implementation of preceptor programmes focusing on the meaning and implications of professionalism.

The importance of socioeconomic factors for compliance and outcome at screening for abdominal aortic aneurysm in 65-year-old men

OBJECTIVE To evaluate compliance with screening and prevalence of abdominal aortic aneurysm (AAA) in relation to background data regarding area-based socioeconomic status. METHODS Our department annually invites 4300 65-year-old men from the city of Malmö and 15 neighboring municipalities to ultrasound AAA screening. In a cross-sectional cohort study, compliance and AAA prevalence among 8269 men were related to background socioeconomic data such as mean income, proportion of immigrants, percentage of subjects on welfare, smoking habits, and unemployment rate in the different municipalities. The 10 different administrative areas in Malmö were evaluated separately. RESULTS Compliance with screening in the entire area was 6630/8269 (80.2%) but varied between 64.4% and 89.3% in different municipalities (P < .001). In univariate analysis, compliance increased with increasing mean income (r = 0.873; P < .001) but decreased with increasing proportion of immigrants (r = -0.685; P =.005) and subjects on welfare (r = -0.698; P = .004). Compliance in 10 different administrative parts of Malmö (P = .002) also increased with increasing mean income (r = 0.948; P < .001), and decreased with increasing proportion of immigrants (r = -0.650; P = .042) and increasing unemployment rate (r = -0.796; P = .006). Altogether, 117 (1.8%) AAAs were found, the prevalence differing between both different municipalities (P =.003) and the 10 different administrative parts of Malmö (P =.02). The prevalence of AAA in the 10 administrative parts of Malmö increased with increasing percentage of smokers (r = 0.784; P = .007), percentage of immigrants (r = 0.644; P = .044), and unemployment rate (r = 0.783; P =.007) but decreased with increasing mean income (r = -0.754; P = .012). CONCLUSIONS Compliance with ultrasound screening for AAA differed between different geographical areas. In areas with low socioeconomic status, compliance rates were lower, whereas AAA prevalence was higher. The identification of contextual factors associated with low compliance is important to be able to allow targeted actions to increase efficacy of ultrasound screening for AAA. Targeted actions to increase compliance in those areas are being scientifically investigated and implemented.

Stress of Conscience among psychiatric nursing staff in relation to environmental and individual factors

The present study aimed at investigating the relationship between environmental and individual factors and Stress of Conscience among nursing staff in psychiatric in-patient care. A questionnaire involving six different instruments measuring Stress of Conscience, the ward atmosphere, the psychosocial work environment, Perceived Stress, Moral Sensitivity, and Mastery was answered by 93 nursing staff at 12 psychiatric in-patient wards in Sweden. The findings showed that Sense of Moral Burden, Mastery, Control at Work and Angry and Aggressive Behavior were related to Stress of Conscience. We conclude that Mastery and Control at Work seemed to work as protective factors, while Sense of Moral Burden and perceptions of Angry and Aggressive Behavior made the nursing staff more vulnerable to Stress of Conscience. Future research should investigate whether measures to increase the level of perceived control and being part of decision making will decrease the level of Stress of Conscience among the staff.

Vacuum-assisted wound closure versus alginate for the treatment of deep perivascular wound infections in the groin after vascular surgery.

BACKGROUND Vacuum-assisted wound closure (VAC) therapy may heal wounds faster than conventional dressings after surgical debridement of perivascular groin infections after vascular surgery. METHODS Patients with deep infected wounds (Szilagyi grade III) were surgically revised and left open for secondary healing, then randomized to either VAC or alginate (Sorbalgon) therapy, between February 2007 and November 2011. To test the hypothesis, it was calculated that 42 patients needed to be included (90% power, 5% level of significance). It was decided to perform an interim analysis after inclusion of 20 patients. RESULTS Among 66 patients undergoing groin revision, 20 patients were included in this study. Patients were randomized to VAC (n = 10) or alginate (n = 10). The two groups were comparable in patient and wound characteristics. Time to full skin epithelialization was significantly shorter in the VAC group (median, 57 days) compared with the alginate group (median, 104 days; P = .026). The number of positive wound cultures of bacteria and C-reactive protein values decreased equally in both groups between surgical revision and day 21. One femur amputation was performed in each group as a consequence of the groin infection, one patient died during the in-hospital stay in the alginate group, and none died in the VAC group. CONCLUSIONS VAC achieves faster healing than alginate therapy after wound debridement for deep perivascular wound infections in the groin after vascular surgery. This finding does not allow further inclusion of patients from an ethical point of view, and this study was, therefore, stopped prematurely.

The ward atmosphere important for the psychosocial work environment of nursing staff in psychiatric in-patient care

BackgroundThe nursing staff working in psychiatric care have a demanding work situation, which may be reflected in how they view their psychosocial work environment and the ward atmosphere. The aims of the present study were to investigate in what way different aspects of the ward atmosphere were related to the psychosocial work environment, as perceived by nursing staff working in psychiatric in-patient care, and possible differences between nurses and nurse assistants.Methods93 nursing staff working at 12 general psychiatric in-patient wards in Sweden completed two questionnaires, the Ward Atmosphere Scale and the QPSNordic 34+. Data analyses included descriptive statistics, the Mann-Whitney U-test, Spearman rank correlations and forward stepwise conditional logistic regression analyses.ResultsThe data revealed that there were no differences between nurses and nurse assistants concerning perceptions of the psychosocial work environment and the ward atmosphere. The ward atmosphere subscales Personal Problem Orientation and Program Clarity were associated with a psychosocial work environment characterized by Empowering Leadership. Program Clarity was related to the staffs perceived Role Clarity, and Practical Orientation and Order and Organization were positively related to staff perceptions of the Organizational Climate.ConclusionsThe results from the present study indicate that several ward atmosphere subscales were related to the nursing staffs perceptions of the psychosocial work environment in terms of Empowering Leadership, Role Clarity and Organizational Climate. Improvements in the ward atmosphere could be another way to accomplish improvements in the working conditions of the staff, and such improvements would affect nurses and nurse assistants in similar ways.

Psychometric properties of the disease-specific health-related quality of life instrument VascuQoL in a Swedish setting

BackgroundTraditional outcome measures in peripheral arterial disease (PAD) provide insufficient information regarding patient benefit. It has therefore been suggested to add patient-reported outcome measures. The main aim of this study was to validate the Swedish Vascular Quality of Life questionnaire (VascuQoL) version, a patient-reported PAD-specific health-related quality of life (HRQoL) instrument.MethodsTwo-hundred PAD patients were consecutively recruited from two university hospitals. Out of the 200 subjects, 129 had intermittent claudication and 71 had critical limb ischemia. Mean age was 70 ± 9 y and 57% of the participants were male. All patients completed SF-36 and VascuQoL at the vascular outpatient clinic, when evaluated for invasive treatment. Risk factors and physiological parameters were registered. Construct validity was tested by correlation analysis versus SF-36 and was also assessed with multitrait/multi-item scaling analysis (MTMI). Sensitivity analysis regarding disease severity identification was performed. Reliability was assessed with Cronbachs alpha and responsiveness by standardized response mean (SRM) calculations.ResultsSignificant correlations were demonstrated between relevant subscales of VascuQoL and SF-36. MTMI showed acceptable construct validity, but some scaling-errors. VascuQoL significantly (p < 0.001) discriminated claudicants from critical limb ischemia patients. Cronbachs alpha was 0.94 and SRM 1.02 (sum score).ConclusionsThe Swedish version of VascuQoL is valid and quantifies central aspects of HRQoL in PAD patients. Sensitivity analysis showed high ability to differentiate between disease severity and SRM illustrated excellent responsiveness. The relative abundance of items however makes use in the everyday clinical setting somewhat difficult.
