<p>Syftet med denna litteraturöversikt var att beskriva den hälsorelaterade livskvaliteten hos patienter med en implantable cardioverter defibrillator (ICD).  Studien genomfördes som en litteraturöversikt, där tolv vetenskapliga artiklar av kvantitativ karaktär analyserades och användes i studiens resultatdel.  Sökorden som användes var <em>Defibrillators, Implantable, Quality of Life </em>och<em> health related. </em>Inklusionskriterier var artiklar skrivna på engelska, peer-reviewed, publicerade från år 2000 och framåt samt deltagarna i dessa studier skulle vara 19 år eller äldre. I studien framkom det att ICD-patienter undvek specifika platser, objekt och fysiska aktiviteter relaterade till ICD:n. Också en oro över bilkörning framkom.  ICD-patienter utsätts för en förändring i livssituation och är i behov av stöd och individuell informationsgivning gällande deras medicintekniska anordning. Idag är största delen av forskning gjord på män, då implantationsfrekvensen är högre hos dessa. Vidare forskning är relevant och bör omfatta kvinnor, för att på så sätt kunna anpassa framtida vårdinsatser på ett individuellt plan. Vårdgivare behöver fördjupad kunskap inom detta område, då implantationsfrekvensen av ICD är ökande. Kunskap hos vårdgivare kan möjligtvis leda till en ökad hälsorelaterad livskvalitet inom denna patientgrupp.</p> / <p>The aim with this literature study was to describe the health related quality of life in patients with an implantable cardioverter defibrillator (ICD). The study was carried out as a literature study and twelve articles, which all were of quantitative character, were analyzed and constituted the result of the study. The search words that were used were <em>Defibrillators, Implantable, Quality of Life </em>and<em> health related. </em>The criteria of inclusion were articles in English, peer-reviewed, published in 2000 to present day and the participants in these studies had to be 19 years or elder. In the study it emerged that ICD-patients avoided specific places, objects and physical activities related to the ICD. Also a concern regarding driving appeared. ICD-patients are subjects of a change in their life situation and are in need of support and individual information regarding their medicine technical device. To this date, the majority of researches are conducted on men, because of the higher implant frequency within this gender. Further researches are of importance and shall enclose the female gender, to be able to adapt the contribution of nursing on an individual level. Health care providers are in need of deepened knowledge within this area, because of the rising frequency of implantation. This knowledge might lead to a increased health related quality of life within this patient group.</p>

The purpose of the current study was to examine putative mediators and moderators in the association between adiposity and anxiety in a sample of overweight and obese youth. In addition, anxiety was examined as a potential moderator between adiposity and health-related quality of life (HRQOL). Participants were youth (N = 137) between 8 and 17 years old (M = 13.09, SD = 2.61) and their legal caregivers recruited from four medical clinics affiliated with the University of South Florida. Youth were primarily overweight (28.5%) or obese (64.2%) and ethnically diverse. Data were analyzed by path analysis. Weight-related teasing significantly mediated the association between adiposity and child reported anxiety, but competency-related teasing and peer victimization were not significant mediators. Internalization of appearance ideals significantly moderated the association between adiposity and anxiety by child report; however, no significant moderations were found for parent report. Additionally, sociocultural pressures to meet appearance ideals were not significant moderators by child or parent report. Notably, anxiety significantly moderated the association between adiposity and social functioning by child report, with those experiencing greater anxiety evidencing poorer social quality of life. However, anxiety did not moderate the association between adiposity and other domains of HRQOL by parent or child report. Given the significant increase in pediatric overweight and obesity in recent decades, it is particularly important to understand the psychosocial implications of excess adiposity in youth. Clinical and research implications are discussed focusing on the mechanisms between adiposity and anxiety and suggested clinical interventions to address said mechanisms.

The present study assessed the relationship between Body Mass Index (BMI) and healthcare cost, utilization and health-related quality of life (HRQoL) of type 2 diabetes patients using the Medical Expenditure Panel Survey (MEPS) database. Study subjects were at least 18 years of age, diagnosed with diabetes and taking ≥1 oral antidiabetic medication. Data were extracted over a 5-year period (01/01/2006-12/31/2010). The main study outcomes were healthcare costs and utilization and HRQoL. The study covariates were age, gender, race, smoking status, census region of residence, marital status, insurance status, Charlson comorbidity index score and additional bed days. Study objectives were addressed using generalized linear model, negative binomial and multivariate regression analyses. A final un-weighted sample size of 7,003 patients was obtained. Mean age (±SE) was 61.2 (±0.24) years, mean BMI (±SE) was 32.2 (±0.12), and 50.4% were males. The majority was white (77.4%), did not smoke (84.5%), and were married (60.4%). Based on BMI categories, 12.6% had normal weight (BMI: 18.0-24.9); 29.2% were overweight (BMI: 25.0-29.9); 45.6% were obese (BMI: 30.0-39.9), and 12.6% were morbidly obese (BMI≥ 40.0). Compared to normal-weight patients; overweight, obese or morbidly obese patients had significantly higher (p<0.05) diabetes-related direct medical costs. However, overweight patients had significantly lower (p=0.021) all-cause direct medical costs. Furthermore, compared to normal weight patients, obese patients had a significantly higher (p=0.009) number of ambulatory care visits, while overweight patients had a significantly lower (p=0.035) number of emergency department visits. In addition, being obese or morbidly obese was associated with a significantly higher (p<0.0001) number of prescribed medicines compared to normal-weight patients. Compared to normal-weight patients; being obese or morbidly obese was also significantly (p<0.0001) associated with lower physical component summary (PCS-12) scores (i.e., worse quality of life) while being overweight was significantly (p=0.038) associated with higher mental component summary (MCS-12) scores (i.e., better quality of life). In conclusion, the present study suggests that among type 2 diabetes patients, being obese may be associated with negative consequences (in terms of healthcare costs, utilization and outcomes). Hence, there is the need to address obesity among type 2 diabetes patients in order to improve their health outcomes and significantly reduce healthcare costs and resource utilization. / text

Problem: Older adults may change their view on what is important to their health-related quality of life (HRQOL). They may alter their opinion about areas relevant to HRQOL (reconceptualization), or how important these areas are to them (reprioritization), and this can be referred to as response shift (RS). Overtime, changes in HRQOL may be imprecise (underestimated or overestimated) if RS occurs. Providing detailed information about RS in the older adult population will have many implications for health professionals, family members, caregivers, policy makers, and researchers. The purpose was to explore RS in HRQOL in community-dwelling older men. Methods: Data from the Manitoba Follow-up Study (MFUS) was used as 360 older men returned the Successful Aging Questionnaire in each of five years (2007-2011). The participants identified the importance of 15 items, which reflect the physical (2 items), mental (5 items), and social domains (8 items) of HRQOL. Descriptive analysis was performed using SPSS21. An individualized method was used to identify different aspects of RS at group and individual levels, as well as the item level. Predictors of RS were also identified using logistic regression in a one-year period. Results: Mean age of participants was 89.7 years (SD 2.9) in 2011. Across 15 items over a one-year period, RS varied from a low of 9.3% for the ‘being mentally aware’ item to 39.3% for the ‘having goals/making plans’ item. Because we were examining RS of 15 items, it was very uncommon to find older men with no RS on all items. Only 27 out of 360 older men (7.5%) provided the same response on all the items they answered at both times (2010-2011). The average of the percent of people showing RS over 15 items, across four time periods, within three domains, was 24.4%. Reprioritization was more common in physical and mental domains, respectively, whereas reconceptualization was seen mainly in the social domain. Further, most of those who showed reprioritization, showed a decrease in importance, while most of those who showed reconceptualization, dropped a concept. Older men who were older, married, living independently, and recently did not participate in activities, were more likely to show RS in certain items. Older men with lower self-rated health were less likely to show RS. Conclusions: Data from the MFUS presents an opportunity to assess RS by using an individualized method that is simple to conduct and interpret in research and clinical settings. This method provides extensive demonstration of RS including magnitude, timing, type, direction, and predictors. RS should be considered an important part of aging, when planning resources and individualizing interventions for the older adult population. Future studies should design a method that evaluates RS individually, similar to our method. / October 2015

Aim: The overall aim of this thesis was to describe and explore how sexuality, body image and HRQoL were affected in patients treated for hematologic malignancies, and their need for support. A further aim was to describe nurses’ conceptions of dialogues about sexuality. Methods: Ten nurses in cancer care (I) and twelve patients were interviewed (II). Data were analysed according to phenomenography (I-II). Data were also collected from patients (≥45 years) included consecutively: at baseline (n=32), one month (n=25; III-IV) and six months (n=20; IV) after treatment. Three instruments were used: SAQ-S, BIS and EORTC QLQ-C30. The data were analysed statistically. Main findings: The nurses (I) conceived that they should talk about sexuality with cancer patients, but usually did not due to their own attitudes, lack of knowledge about sexuality, communication skills and environmental conditions. The patients (II) experienced negative effects on sexual function and sexual relationship due to affected strength and sexual desire. The patients’ sexuality, body image and HRQoL were affected during (II-III) and one month after treatment (III-IV). Patients recovered with regard to these issues within six months, except for sexual relationship (IV). However, when the disease and side effects were experienced as severe, thoughts about and interest in sexuality were overshadowed, and the need or wish for support related to this issue was low (II). Sexuality and body image seemed to influence changes in HRQoL (IV). Conclusion: Patients above the age of 45 treated for hematologic malignancies with chemoimmunotherapy experienced problems related to sexuality, body image and HRQoL. However, as sexuality was found to be of low priority due to concerns for life when the disease and side effects were severe, support must be timely and individualized. Patient-centered care, with patients continuously meeting a nurse guided by the idea of holistic individual nursing care throughout the care trajectory, is suggested. / Sexuality is to a large extent seen as a private and sensitive topic by both patients and nurses in cancer care. The patients in this thesis were above the age of 45 and treated with chemo- or chemoimmunotherapy for hematologic malignancies. They experienced affected sexuality, body image and HRQoL during and after treatment. The importance of sexuality was low and sexuality seemed to be overshadowed when the disease and side effects were experienced as severe. Few patients described that information might have been helpful.  In order to avoid violating patients’ integrity, one challenge is to identify patients who ascribe importance to sexuality and who also want support regarding sexuality. One way is to organize care in a patient-centered way, with patients continuously meeting a nurse guided by the idea of holistic individual nursing care throughout the care trajectory. Furthermore, nurse educators’ need to acknowledge this area and the health care leaders should provide nurses opportunities to discuss attitudes and personal barriers to sensitive issues such as sexuality

The objective of this study was to contribute evidence regarding the use of the SF6D and HUI3 in persons with neurological conditions. The data of 776 individuals from the LINC Study was analyzed. The mean utility score of the HUI3 was 0.47 (95% CI 0.45, 0.49) and SF6D was 0.62 (95% CI 0.62, 0.63). Even though the SF6D and HUI3 were sensitive to a variety of HRQoL domains relevant to persons with neurological conditions, they showed only marginal agreement (ICC of 0.41) with a mean utility difference of 0.15 (95% CI 0.13, 0.17). Discordance varied systematically with HRQoL status and was consistent regardless of the participant or impairment characteristics present. Despite sharing a common purpose, the substantial and clinically important differences found between the SF6D and HUI3 cast doubt on whether the utility estimates produced by these instruments are directly comparable or universally valid.

This study assesses generic and disease-specific Health-Related Quality of Life (HRQOL) in children and adolescents with Inflammatory Bowel Disease (IBD). More specifically, the purpose of the study is to address the relationship between disease- specific indicators, both on a symptom-by-symptom basis and as a whole, to overall HRQOL. Self- and proxy-report versions of the Pediatric Quality of Life Inventory™ (PedsQL™) Generic Core Scales and the newly developed Pediatric Quality of Life Inventory™ Gastrointestinal Symptoms Module were administered to 187 parent-child dyads at ten study sites across the United States. Disease-specific indicators included: stomach pain, stomach upset, trouble swallowing, heartburn and reflux, gas and bloating, constipation, and diarrhea. It was hypothesized that caregiver- and child-reported disease-specific HRQOL would be positively correlated with generic HRQOL, and that physical disease-specific indicators would contribute the greatest variance in total generic HRQOL scores, for both self and proxy report. Results confirmed the hypothesis that disease-specific HRQOL would be positively correlated with generic HRQOL for children and caregivers. Multivariate regression results revealed that the Stomach Pain and Hurt, Worry, Medicines, and Communication scales contributed the most variance to overall HRQOL scores for children. The same analysis performed for parent ratings yielded one statistically significant scale: Worry. In essence, intervention efforts aimed at reducing the influence of worry and anxiety may prove more effective in improving HRQOL outcomes than interventions targeting reduction of physical symptoms.

Background: Exemestane is a drug of great interest for breast cancer prevention, because it inhibits estrogen production. Estrogen may operate by increasing breast density, a well-established biomarker for increased breast cancer risk. The NCIC CTG MAP.2 trial examined the efficacy of exemestane in decreasing breast density. Menopausal health-related quality of life (HRQL) and adverse events were also carefully monitored during the study. Purpose: To elucidate the impact of exemestane on menopausal HRQL and to examine the relationship between clinician and participant methods of reporting side effects. Methods: 98 postmenopausal women with increased breast density were randomized to exemestane or placebo daily for one year. HRQL was measured with the MENQOL questionnaire, which has four domains. Mean changes in MENQOL domain scores from baseline were compared between treatment groups using the Wilcoxon rank-sum test. The difference between groups in the proportion of women with a clinically meaningful decline was compared by domain with the Chi-square test; change scores were considered worsened if increased by ≥ 0.5 points. The association between time-to-decline in menopausal HRQL and treatment was evaluated using Cox PH regression. The kappa statistic quantified the level of agreement between participant-reported and clinician-reported symptoms. Kaplan-Meier estimates of time-to-decline as communicated by clinicians and participants were compared, using three thresholds to define meaningful change. Results: No significant differences in mean change scores were detected, however, a significantly greater proportion of women on exemestane experienced a clinically meaningful decline in physical menopausal HRQL at three months (absolute difference=19%, p= 0.03), while the absolute difference approached significance for vasomotor menopausal HRQL at six months (21%, p= 0.05), and at nine months (21%, p=0.06). The rate of decline in physical menopausal HRQL was 2.08 times greater (95% CI 1.10-3.94) in the exemestane group compared to the placebo group. Agreement between raters was low for all symptoms except hot flashes; in general participants detected symptoms more rapidly than clinicians, regardless of the defined cut-off for meaningful change on the MENQOL. Conclusions: A subset of women on exemestane experienced significant declines in physical and vasomotor symptoms. Generally, participants reported symptoms more frequently and faster than clinicians. / Thesis (Master, Community Health & Epidemiology) -- Queen's University, 2012-06-06 23:55:24.011

Measurement invariance (MI) is a prerequisite to conduct valid comparisons of Health-related quality of life (HRQOL) measures across distinct populations. This research investigated the performance of estimation methods for testing MI hypotheses in complex survey data using a simulation study, and demonstrates the application of these methods for a HRQOL measure. Four forms of MI were tested using confirmatory factory analysis. The simulation study showed that the maximum likelihood method for small sample size and low intraclass correlation (ICC) performed best, whereas the pseudomaximum likelihood with weights and clustering effects performed better for large sample sizes with high ICC to test configural invariance. Both methods performed similarly to test other forms of MI. In the numeric example, MI of one HRQOL measure in the Canadian Community Health Survey was investigated and established for Aboriginal and non-Aboriginal populations with chronic conditions, indicating that they had similar conceptualizations of quality of life.
