A pilot study assessing the impact of a learner-centered adult asthma self-management program on psychological outcomes

Factors associated with depressive symptoms in uncontrolled asthmatics

RATIONALE

Recent epidemiological data indicate that approximately 6.7% of US adults suffer from depression in any given year. The purpose of the study is to identify factors associated with depressive symptoms in a large diverse group of patients with poorly controlled asthma. The factors include quality of life (QOL), lung function, asthma knowledge, attitudes, self-efficacy, symptoms and control of disease.

METHODS

Baseline characteristics of a cohort of 599 subjects with asthma recruited from twenty Asthma Clinical Research Centers across the United States were examined. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to stratify subjects into those with depressive symptoms (CES-D score ≥ 16) and those without depressive symptoms (CES-D < 16). Bivariate statistics were used to compare the two groups; additionally, logistic regression was used to determine factors that have the greatest association with depressive symptoms.

RESULTS

Subjects with depressive symptoms had significantly lower QOL scores and less knowledge about their disease than subjects with no depression; however, lung function (FEV1%) and asthma control were not significantly associated with depressive symptoms in the logistic regression analysis. Subjects who were non-white had lower household income, high school diploma or less, and those who were unemployed or disabled had significantly higher scores for depressive symptoms.

CONCLUSION

Subjects with depressive symptoms have significantly less knowledge of their disease and poorer QOL compared to those without depressive symptoms. Evaluating depressive symptoms in subjects with asthma will provide a more complete picture of their overall condition. The role of asthma education on depressive symptoms in this population needs to be further investigated. The effect of QOL on treating depression in asthma patients also needs to be studied.

Examining the effect of patient-centred care on outcomes

Within patient-centered care (PCC), the individual is viewed as an active member of the healthcare team. While there has been recent interest in conducting systematic reviews to examine the effectiveness of PCC interventions, various studies fall short in explaining the type of intervention most effective in producing significant changes to desired outcomes. The purpose of this systematic review was to determine the characteristics of PCC interventions that have demonstrated effectiveness in enhancing the quality of care and performance of self-care behaviours. A systematic review of 40 studies that addressed PCC interventions, included samples over the age of 18 years, and were published between 1995 and 2014 was performed. Descriptive statistics were used to delineate study, participant, and intervention characteristics. Results suggest PCC-based interventions are not effective when delivered to individuals living with chronic illnesses.

Persistent differences in asthma self-efficacy by race, ethnicity, and income in adults with asthma

OBJECTIVE

The objective of this population-based study was to determine if and to what extent there are differences in asthma self-efficacy by race/ethnicity and income, and whether health status, levels of acculturation, and health care factors may explain these differences.

METHODS

We conducted a secondary data analysis of asthma self-efficacy using the 2009 and 2011-2012 California Health Interview Survey, in adults with asthma (n=7874). In order to examine if and how the effect of race/ethnicity and income on asthma self-efficacy may have been altered by health status, acculturation, and health care factors, we used staged multivariable logistic regression models. We conducted mediation analyses to evaluate which of these factors might mediate disparities in self-efficacy by race/ethnicity and income.

RESULTS

69.8% of adults reported having high asthma self-efficacy. Latinos (OR 0.66; 95% CI 0.51-0.86), African-Americans (OR 0.50; 95% CI 0.29-0.83), American Indian/Alaskan Natives (OR 0.55; 95% CI 0.31-0.98) and Asian/Pacific Islanders (OR 0.34; 95% CI 0.23-0.52) were less likely to report high self-efficacy compared to Whites. Individuals with income below the federal poverty level (OR 0.56; 95% CI 0.40-0.78) were less likely to report high self-efficacy compared to higher income individuals. The relationship between income and self-efficacy was no longer significant after further adjustment for health care factors; however, the differences in race and ethnicity persisted. Receiving an asthma management plan mediated the relationship in certain subgroups.

CONCLUSIONS

Addressing modifiable health care factors may play an important role in reducing disparities in asthma self-efficacy.

Depression in the elderly with visual impairment and its association with quality of life

Background

Visual impairment is more prevalent in the elderly and depression is common in this population. Although many studies have investigated depression or quality of life (QOL) in older adults with visual impairment, few have looked at the association between these two concepts for this population. The aim of this systematized review was to describe the association between depression and QOL in older adults with visual impairment.

Methods

A search was done using multiple electronic databases for studies addressing the relationship between QOL and depression in elders with visual impairment. The concept of QOL was divided into two different approaches, ie, QOL as achievement and QOL as subjective well-being. Comparison of QOL scores between participants with and without depression (Cohen’s d) and correlations between depression and QOL (Pearson’s r) were examined.

Results

Thirteen studies reported in 18 articles were included in the review. Nearly all of the studies revealed that better QOL was moderately to strongly correlated with less severe depressive symptoms (r = 0.22–0.68 for QOL as achievement; r = 0.68 and 0.72 for QOL as subjective well-being). Effect sizes for the QOL differences between the groups with and without depression ranged from small to large (d = 0.17 to 0.95 for QOL as achievement; no data for QOL as subjective well-being).

Conclusion

Additional studies are necessary to pinpoint further the determinants and mediators of this relationship. Considering the high prevalence rate of depression in this community and its disabling effects on QOL, interventions to prevent and treat depression are essential. More efforts are needed in clinical settings to train health care practitioners to identify depressed elders with visual impairment and provide appropriate treatment.

Decay of impact after self-management education for people with chronic illnesses: changes in anxiety and depression over one year

BACKGROUND

In people with chronic illnesses, self-management education can reduce anxiety and depression. Those benefits, however, decay over time. Efforts have been made to prevent or minimize that "decay of impact", but they have not been based on information about the decay's characteristics, and they have failed. Here we show how the decay's basic characteristics (prevalence, timing, and magnitude) can be quantified. Regarding anxiety and depression, we also report the prevalence, timing, and magnitude of the decay.

METHODS

Adults with various chronic conditions participated in a self-management educational program (n = 369). Data were collected with the Hospital Anxiety and Depression Scale four times over one year. Using within-person effect sizes, we defined decay of impact as a decline of ≥0.5 standard deviations after improvement by at least the same amount. We also interpret the results using previously-set criteria for non-cases, possible cases, and probable cases.

RESULTS

Prevalence: On anxiety, decay occurred in 19% of the participants (70/369), and on depression it occurred in 24% (90/369). Timing: In about one third of those with decay, it began 3 months after the baseline measurement (6 weeks after the educational program ended). Magnitude: The median magnitudes of decay on anxiety and on depression were both 4 points, which was about 1 standard deviation. Early in the follow-up year, many participants with decay moved into less severe clinical categories (e.g., becoming non-cases). Later, many of them moved into more severe categories (e.g., becoming probable cases).

CONCLUSIONS

Decay of impact can be identified and quantified from within-person effect sizes. This decay occurs in about one fifth or more of this program's participants. It can start soon after the program ends, and it is large enough to be clinically important. These findings can be used to plan interventions aimed at preventing or minimizing the decay of impact.

Asthma education and health outcomes of children aged 8 to 12 years

The purpose of this study was to evaluate the health outcomes of 8- to 12-year-old urban-dwelling children with moderate to severe persistent asthma who participated in a modified Open Airways for Schools (OAS) asthma education program. It was hypothesized that the intervention group would have improved health outcomes when compared to control. A 2-group, 3-points-in-time method was used to conduct the study. The intervention group demonstrated significant and sustained improvement in asthma knowledge. There was no significant difference between groups for quality of life or pulmonary function. While OAS is a good program for asthma education, the program alone may not be sufficient to improve risk factors associated with poor pulmonary function. Future studies should incorporate environmental interventions.

Implementing a change to a learner-centered philosophy in a school of nursing: faculty perceptions

This qualitative study explores faculty experiences with their school of nursing's change to a learner-centered teaching philosophy. The primary research goals were to determine what change conditions faculty perceived as significant and how they viewed overall faculty progress and unity in adopting the philosophy. Nine nurse faculty members from a four-year public university were interviewed and also responded to two narrative questionnaires over a period of three months. Thematic analysis revealed five categories with a total of 20 themes. Certain conditions were found to be important to the process, such as availability of time and resources. Other conditions were found to be of lesser importance, such as dissatisfaction with the status quo and participation in the decision to make the change. This study provides an in-depth understanding of how one nursing faculty group experienced the implementation of change to a learner-centered philosophy.

Analysis of the relation between level of asthma control and depression and anxiety

BACKGROUND

Frequent co-existence of bronchial asthma and depression or anxiety is an unquestioned phenomenon. In contrast, little is known about the relationship between the degree of asthma control and the prevalence of depression and anxiety. The aim of this study was to determine the potential relationship between the degree of asthma control and the prevalence of depression and anxiety.

MATERIAL/METHODS

This study included a group of 128 randomly selected asthmatic individuals with various degree of asthma control. The study was based on a questionnaire survey, using the following tools: the Asthma Control Test, Beck Depression Inventory, and State-Trait Anxiety Inventory (STAI) - X-1 and X-2 questionnaires. All the questionnaires were completed during a single follow-up visit at the clinic.

RESULTS

The occurrence of depression and its severity significantly correlated with the degree of asthma control. Individuals with depression were characterized by a significantly lower degree of asthma control compared to depression-free individuals (p<0.001). The degree of asthma control decreased significantly with increasing severity of depression (R=-0.367; p<0.001). No significant correlation was observed between the degree of asthma control and the levels of trait anxiety (R=-0.095; p=0.295) and state anxiety (R=-0.093; p=0.308).

CONCLUSIONS

The prevalence of depression and its severity significantly correlate with the degree of asthma control. Large, standardized multicenter studies of the relationship between the degree of asthma control and the prevalence of depression and other psychopathological symptoms are needed. Furthermore, it seems reasonable to introduce the screening of asthmatics for mental disorders.

Yes we can! Improving medical screening for intimate partner violence through self-efficacy

BACKGROUND

Because individual practitioner's commitment to routine screening for IPV is the greatest predictor that women will be screened and referred for services, it is vital that screeners are dedicated, knowledgeable, and confident in their ability to recognize and assist victims of violence. Self-efficacy has been consistently linked in the literature with successful outcomes.

OBJECTIVES

Intimate partner violence (IPV) constitutes a major public health problem. In the absence of Federal or State regulation, individual hospitals and systems are left to develop their own policies and procedures. This paper describes the policies and procedures developed by an American domestic violence counseling and resource center.

DESIGN

Post test surveys were used.

SETTINGS

Hospitals, medical offices, and medical schools surrounding an urban area in Pennsylvania participated.

PARTICIPANTS

320 nurses and medical students participated in training provided by a domestic violence center.

METHODS

Post test surveys measured self-efficacy, the perceived usefulness of screening the accessibility of victim services, understanding of obstacles faced by victims, and knowledge-level regarding local IPV services. Participants also self-reported their gender, age, race, and position with the hospital system.

RESULTS

Nurses and medical interns exhibit a wide range of self-efficacy regarding their ability to screen victims of intimate partner violence. Intimate partner violence (IPV) training yielded participants who were better informed about IPV services and the obstacles faced by victims.

CONCLUSIONS

In the absence of uniform screening guidelines, hospitals, systems, and individual practitioners must be vigilant in screening procedures. Partnerships with women's centers may provide valuable resources and training that may ultimately improve patient care. ‎

Asthma and ageing: an end user's perspective--the perception and problems with the management of asthma in the elderly

Despite the high prevalence of asthma in the elderly, its development, diagnosis, and treatment are under-researched. This paper provides a comprehensive review of the current state of knowledge in relation to management of asthma in the elderly - focusing on barriers to diagnosis and treatment and the central role of self-management. Asthma prevalence increases with age, as does the risk of dying from asthma, and with the ageing of the population and increasing life expectancy, the prevalence of (diagnosed and undiagnosed) asthma in older adults is expected to increase drastically, placing an increasing burden on sufferers, the community and health budgets. Asthma sufferers are more likely to be psychologically distressed and at a higher risk of anxiety and depression, more likely to experience a sense of lack of control over their health and to have lower self-reported quality of life. Asthma is under-diagnosed, and under-treated, in the elderly, further exacerbating these negative consequences. The review concludes, among other things, that there is a need to better understand the development and impact of asthma in the elderly, to increase community awareness of asthma in the elderly, to improve both 'medical management' and 'self-management' in this population and to develop more effective tools for diagnosis and treatment of asthma in the elderly. The paper concludes with key recommendations for future research and practice in this area.

A Randomized Controlled Behavioral Trial of a New Adult Asthma Self-management Program

Aims: The purpose of the present research was to design and implement an adult asthma self-management program using a randomized control design.

Methods: A total of 24 participants served in the control group while 21 participants served in the intervention group. Those in the intervention group participated in 7 weekly meetings which consisted of interactive discussions, problem-solving, social support and a behavior modification procedure. The behavior modification procedure consisted of homework assignments in which participants were asked to self-monitor and record asthma specific behaviors (including peak expiratory flow, avoidance/removal of asthma triggers, and controller medication adherence) and general lifestyle behaviors (including drinking water, practicing relaxation, washing hands and exercising).

Results: A series of two factor mixed design analysis of variance computations indicated statistically significant interactions. When compared to participants in the control condition, those individuals who participated in the intervention had significant improvements in asthma self-efficacy, asthma quality of life, and patient activation. Significant interactions also indicated that those in the intervention groups had increases in the frequencies of the following self-reported behaviors: 1) reducing asthma triggers; 2), reading about asthma; 3) peak flow monitoring; 4) exercising, and; 5) hand washing. Follow-up data 2 months after the intervention indicated maintenance for many of the psychological, cognitive and behavioral changes.

Conclusions: These results confirm that our adult asthma selfmanagement program can lead to improvements in short term outcomes.
