[Psychoeducational and cognitive behavioral treatments of bipolar disorder].

UNLABELLED: Bipolar disorder is a severe mood disorder characterized by recurrence of mania and depression. Despite the use of mood stabilizers, a significant proportion of bipolar patients experience relapse, psychosocial impairment and persistent symptoms. A significant part of patients show poor adhesion to the pharmacological treatment. This article aims to provide an overview of research focusing on psychoeducational and cognitive-behavioral treatment (CBT) of bipolar patients. METHOD: Studies were identified through Medline searches between 1971 and 2005. RESULTS: Studies on bipolar patients suggest that psychoeducational interventions may improve treatment adherence, illness knowledge, ability to cope with early manic symptoms and tend to reduce the risk of manic relapses. CBT tends to diminish depressive symptoms, improve treatment adherence and reduce the risk of depressive and manic relapses. Most psychoeducational and CBT studies share a common medical model of the illness, thereby making clear distinctions of impact of each intervention difficult. Few studies focused on patients with problems with mood stabilizers adherence. It is now important to develop specific interventions for those patients. CONCLUSION: According to these studies, bipolar patients are likely to benefit from psychoeducational or CBT interventions added to usual pharmacotherapy. In order to overcome limitations of existing research, future studies should adjust for the effect of pharmacological treatment, the type and severity of psychopathology at baseline, the acceptance of and the adaptability to the illness and it's awareness.

Adherence: a necessity for successful HIV combination therapy.

Patient adherence to combination therapy is a critical component of successful treatment outcomes. While combination therapy is known to be effective in slowing disease progression, the long-term benefit of these therapies can only be sustained if resistant strains of HIV do not emerge. Among factors that can result in the emergence of resistance, non-adherence is perhaps the most amenable to intervention. To maximize intervention efforts, a program of research on adherence is needed. A prerequisite for progress in adherence research is a focused effort on developing reliable and valid methods for measuring adherence that are feasible for patients living with HIV/AIDS. If new adherence assessment procedures cannot be developed, it would be helpful if a consensus on measurement approaches could be achieved. This consensus might propose strategies for matching measurement approaches with research questions and recommendations for the use of multiple measures where appropriate. It is important that research continue to identify psychological, physiological, socio-cultural and environmental factors that are associated with non-adherence in various populations both in the developed and the developing world. Intervention programs that address these risk factors and promote adherence need to be developed and evaluated in controlled clinical trials. These programs will need to be tailored to different populations and cultural groups, and tested in both developed and developing countries where HIV therapies are being prescribed. The results of this research would significantly contribute to efforts to prevent virus breakthrough and, by doing so, assist persons living with HIV/AIDS in achieving the health benefits that the combination therapies offer.

Characteristics of inner-city children with asthma: the National Cooperative Inner-City Asthma Study.

Asthma morbidity has increased dramatically in the past decade, especially among poor and minority children in the inner cities. The National Cooperative Inner-City Asthma Study (NCICAS) is a multicenter study designed to determine factors that contribute to asthma morbidity in children in the inner cities. A total of 1,528 children with asthma, ages 4 to 9 years old, were enrolled in a broad-based epidemiologic investigation of factors which were thought to be related to asthma morbidity. Baseline assessment included morbidity, allergy evaluation, adherence and access to care, home visits, and pulmonary function. Interval assessments were conducted at 3, 6, and 9 months after the baseline evaluations. Over the one-year period, 83% of the children had no hospitalizations and 3.6% had two or more. The children averaged 3 to 3.5 days of wheeze for each of the four two-week recall periods. The pattern of skin test sensitivity differed from other populations in that positive reactions to cockroach were higher (35%) and positive reactions to house dust mite were lower (31%). Caretakers reported smoking in 39% of households of children with asthma, and cotinine/creatinine ratios exceeded 30 ng/mg in 48% of the sample. High exposure (> 40 ppb) to nitrogen dioxide was found in 24% of homes. Although the majority of children had insurance coverage, 53% of study participants found it difficult to get follow-up asthma care. The data demonstrate that symptoms are frequent but do not result in hospitalization in the majority of children. These data indicate a number of areas which are potential contributors to the asthma morbidity in this population, such as environmental factors, lack of access to care, and adherence to treatment. Interventions to reduce asthma morbidity are more likely to be successful if they address the many different asthma risks found in the inner cities.

Colorectal carcinoma screening among Hispanics and non-Hispanic whites in a rural setting.

BACKGROUND: Colorectal carcinoma ranks as the second most common cancer and the second leading cause of cancer death in the United States. Hispanics are less likely than their non-Hispanic white counterparts to have ever received a fecal occult blood test (FOBT) or sigmoidoscopy/colonoscopy. Little is known about the barriers to screening in the Hispanic population. METHODS: The authors used baseline data from a community randomized trial of cancer prevention to compare screening prevalence and the associations between reported barriers and screening participation between Hispanics (n = 137) and non-Hispanic whites (n = 491) age > or = 50 years. RESULTS: Hispanics were less likely than non-Hispanic whites to have ever received an FOBT (P = 0.003) or sigmoidoscopy/colonoscopy (P = 0.001). No significant difference across ethnic groups was observed in the prevalence of recent screening using FOBT (29.8% for Hispanics vs. 34.5% for non-Hispanic whites; P = 0.41), but recent use of sigmoidoscopy/colonoscopy was lower for Hispanics (24.1% for Hispanics vs. 33.7% for non-Hispanic whites; P 0.06). Lacking health care coverage or having few years of education were directly associated with failure to ever receive an FOBT or sigmoidoscopy/colonoscopy. CONCLUSIONS: Interventions to improve adherence to colorectal carcinoma screening recommendations among Hispanics should target initial screening examinations, particularly among those lacking health care coverage or having low levels of education.

Sociodemographic predictors of pap test receipt, currency and knowledge among Australian women.

BACKGROUND: Knowledge of sociodemographic variations in cervical cancer screening can help identify population groups at risk of underutilization of cervical cancer procedures and practices. The aim of this research was to examine sociodemographic predictors of receipt, currency (being up-to-date for), and knowledge of Pap test. METHODS: We used data from the 1995 National Health Survey. A subsample of women was given self-administered questionnaires that included questions about the Pap test. The sample size was 7,572. Using multiple logistic regression, we examined the association of age, marital status, region of residence, country of birth, Index of Relative Socioeconomic Disadvantage (IRSD), and education with Pap test receipt, currency, and knowledge. RESULTS: Women under 30 and over 49 years of age, those not presently married, those with lower levels of education, and those born in the Middle East or Asia (compared with the Australian/New Zealand-born women) were at a greater risk of not receiving and having no knowledge of Pap test. CONCLUSIONS: The results of this study suggest that, as part of a comprehensive cancer screening strategy, women who are unlikely to obtain a Pap smear might benefit from targeted interventions to improve adherence to cervical cancer screening programs.

Can human error theory explain non-adherence?

OBJECTIVE: To apply human error theory to explain non-adherence and examine how well it fits. METHOD: Patients who were taking chronic medication were telephoned and asked whether they had been adhering to their medicine, and if not the reasons were explored and analysed according to a human error theory. RESULTS: Of 105 patients, 87 were contacted by telephone and they took part in the study. Forty-two recalled being non-adherent, 17 of them in the last 7 days; 11 of the 42 were intentionally non-adherent. The errors could be described by human error theory, and it explained unintentional non-adherence well, however, the application of 'rules' was difficult when considering mistakes. The consideration of error producing conditions and latent failures also revealed useful contributing factors. CONCLUSION: Human error theory offers a new and valuable way of understanding non-adherence, and could inform interventions. However, the theory needs further development to explain intentional non-adherence.

Methods and applications of quality-of-life measurement during antihypertensive therapy.

The measurement and evaluation of health-related quality of life during antihypertensive therapy has contributed to physicians' understanding of how patients respond to therapy in terms of physical, psychological, and social well-being. Comparative clinical trials of antihypertensive drug therapies have demonstrated that treatment produces no perceptible improvements in health status. Thus, the "burden" of the therapeutic regimen from the patient's perspective is greatly magnified. Research has also demonstrated that patient expectation and preference are important components of quality-of-life assessment when the purpose of this assessment is to predict or explain human behavior. Drug properties, including mechanism of action and pharmacokinetics, have been shown to influence the impact of drug side effects and the degree to which patients tolerate therapy. Researchers have attempted to standardize the construct of quality of life to have broad applications in health care policy and management; however, clinical research in hypertension should focus on the components of health-related quality of life that influence patient outcomes with regard to behaviors affecting adherence. Antihypertensive agents that maximize patient acceptance and quality of life are now available. Future quality-of-life research should be directed toward learning more about human behavior so that adherence to nonpharmacologic interventions such as diet and exercise will be enhanced.

Assessment of adherence to a low-fat diet for breast cancer prevention.

BACKGROUND: The relationships between self-reported adherence to a low-fat diet in healthy women between the ages of 44 and 69 and a number of correlates of this self-reported behavior were examined in an attempt to improve monitoring of adherence to nutritional intervention trials for breast cancer prevention. METHODS: Dietary fat intake in 87 women who completed 6 months of nutritional intervention was reduced from 38.2 +/- 5.9% to 21.7 +/- 7.8% of total energy intake (P less than 0.005). Reported total calorie intake was reduced by approximately 20%. RESULTS: Body weight decreased by 2.7% from 68.1 +/- 11.2 kg to 66.3 +/- 11.9 kg (P less than 0.05). Fasting total plasma cholesterol levels decreased from 205 +/- 31 mg/dl to 184 +/- 29 mg/dl (P less than 0.05). Fasting plasma triglyceride levels did not change significantly (97 +/- 44 mg/dl vs 101 +/- 55 mg/dl). Relative percentage changes in body weight correlated with percentage changes in dietary fat intake (r = 0.23, P less than 0.05). CONCLUSION: Self-reported changes in dietary behavior correlated significantly with objective changes in body weight and fasting cholesterol in these healthy women encouraged to consume a low-fat diet for prevention of breast cancer.

Correlates of maintenance of a low-fat diet among women in the Women's Health Trial.

BACKGROUND: The Women's Health Trial (WHT) was a feasibility study for a randomized controlled trial designed to test the hypothesis that a reduction in dietary fat reduces breast cancer incidence among women age 45 to 69. Between 1984 and 1988, 2,064 women participated in its two phases. METHODS: A follow-up study of 525 women who were randomized to receive the WHT dietary intervention program was conducted to assess maintenance of the diet 1 year on average after the trial ended. Among 448 participants, the mean percentage of energy from fat as measured by a food frequency questionnaire was 40.0% at baseline, 26.3% at the end of the trial, and 27.7% at follow-up. Based on 408 women with complete data, a recursive model was estimated, describing the influence of baseline characteristics of the women on attendance at intervention program sessions, adherence to the diet during the trial, and long-term maintenance of the diet after the trial ended. The effects of women's experiences during the trial on adherence and long-term maintenance were investigated as well. RESULTS: Attendance at the educational sessions was strongly related to adherence to the diet during the trial (P less than 0.001), and adherence was the most important predictor of long-term maintenance (P less than 0.001). The percentage of energy from dietary fat at baseline was an important correlate of both adherence (P less than 0.001) and long-term maintenance (P less than 0.001). College-educated women were more likely to adhere to the diet during the trial (P less than 0.001). Feelings of deprivation adversely affected long-term maintenance (P less than 0.01), primarily through their effect on adherence during the trial (P = 0.01). Costliness of the diet in time and money negatively influenced long-term maintenance (P less than 0.05). Development of a distaste for fat encouraged adherence (P = 0.06). CONCLUSIONS: The low-fat dietary pattern established during the WHT was maintained for as long as 20 months after the trial ended. A recursive model was useful in analyzing the process and correlates of long-term maintenance of dietary behavior change. Both predisposing variables and women's experiences while on a low-fat diet were associated with long-term maintenance. The results suggest that feelings of deprivation should be avoided, perhaps by use of low-fat substitutes, by those attempting to lower their dietary fat and that more research is needed on the development of a distaste for fat among individuals who adopt low-fat diets.

Issues in the planning and conduct of randomised trials.

Randomised trials top the hierarchy of evidence. To provide the best evidence to guide surgical practice, randomised trials must answer clinically important questions, have important and objective outcome measurement and be sufficiently powered to detect important differences between interventions. Investigators who adhere to these principles are more likely to succeed during the conduct of their trials.

What constitutes success in preventive health care? A case study in assessing the benefits of hip protectors.

The economic success of preventive health programs is typically assessed by the net health-related utility gain or loss to society relative to the cost. Issues relating to the positive or negative utility associated with participating in a preventive health program are often ignored. However, it is likely that calls for informed consumer choice and respect for patient autonomy will provide an impetus to examine utility associated with the process and outcomes of preventive health programs. In this paper, we outline the nature of the ex ante and ex post perspective in evaluating benefits and the presence of process utility and the utility of gambling in individual's utility function for preventive health care. The implications of including process attributes and psychological states when assessing benefits to society are discussed in relation to an empirical study on the value of external hip protectors for the prevention of hip fractures. We demonstrate that wearing hip protectors and the psychological outcomes of being a participant in the program can have a significant impact on individual's assessment of the benefits. Furthermore, point of reference plays a crucial role in their valuation. Individuals who did not consent to participate in a trial of hip protectors valued all states significantly lower than those who did participate in the trial. We argue that the utility associated with adherence to the intervention is an important issue for preventive health policy. From the viewpoint of applied welfare economics, evaluation of preventive health programs should allow for both process and outcome utility when assessing benefits. In this context, success might be viewed as maximising the opportunity for individuals to make an informed choice.

Factors influencing medication adherence beliefs and self-efficacy in persons naive to antiretroviral therapy: a multicenter, cross-sectional study.

It is widely recognized that adherence to antiretroviral therapy is critical to long-term treatment success, yet rates of adherence to antiretroviral medications are frequently subtherapeutic. Beliefs about antiretroviral therapy and psychosocial characteristics of HIV-positive persons naive to therapy may influence early experience with antiretroviral medication adherence and therefore could be important when designing programs to improve adherence to antiretroviral therapy. As part of a multicenter AIDS Clinical Trial Group (ACTG 384) study, 980 antiretroviral-naive subjects (82% male, 47% White, median age 36 years, and median CD4 cell count 278 cells/mm3) completed a self-administered questionnaire prior to random treatment assignment of initial antiretroviral medications. Measures of symptom distress, general health and well-being, and personal and situational factors including demographic characteristics, social support, self-efficacy, depression, stress, and current adherence to (nonantiretroviral) medications were recorded. Associations among variables were explored using correlation and regression analyses. Beliefs about the importance of antiretroviral adherence and ability to take antiretroviral medications as directed (adherence self-efficacy) were generally positive. Fifty-six percent of the participants were "extremely sure" of their ability to take all medications as directed and 48% were "extremely sure" that antiretroviral nonadherence would cause resistance, but only 37% were as sure that antiretroviral therapy would benefit their health. Less-positive beliefs about antiretroviral therapy adherence were associated with greater stress, depression, and symptom distress. More-positive beliefs about antiretroviral therapy adherence were associated with better scores on health perception, functional health, social-emotional-cognitive function, social support, role function, younger age, and higher education (r values = 0.09-0.24, all p < .001). Among the subset of 325 participants reporting current use of medications (nonantiretrovirals) during the prior month, depression was the strongest correlate of nonadherence ( r = 0.33, p < .001). The most common reasons for nonadherence to the medications were "simply forgot" (33%), "away from home" (27%), and "busy" (26%). In conclusion, in a large, multicenter survey, personal and situational factors, such as depression, stress, and lower education, were associated with less certainty about the potential for antiretroviral therapy effectiveness and one's perceived ability to adhere to therapy. Findings from these analyses suggest a role for baseline screening for adherence predictors and focused interventions to address modifiable factors placing persons at high risk for poor adherence prior to antiretroviral treatment initiation.

Applying cognitive-social theory to health-protective behavior: breast self-examination in cancer screening.

This article applies recent developments in cognitive-social theory to health-protective behavior, articulating a Cognitive-Social Health Information Processing (C-SHIP) model. This model of the genesis and maintenance of health-protective behavior focuses on the individual's encodings and construals, expectancies, affects, goals and values, self-regulatory competencies, and their interactions with each other and the health-relevant information in the course of cognitive-affective processing. In processing health information, individuals are assumed to differ in both the accessibility of these mental representations and the organization of relationships among them. In this article, the model is applied to analyze and integrate the often-confusing findings on breast self-examination in cancer screening. Implications are considered for assessments and interventions to enhance adherence to complex, long-term, health-protective regimens, tailored to the needs and characteristics of the individual.

Post-prandial plasma ghrelin levels in people with different breakfast hours.

OBJECTIVES: To investigate the changes in post-meal plasma ghrelin levels in people with different breakfast hours. DESIGN AND INTERVENTIONS: The subjects adhered to strict breakfast times starting 2 weeks before the study. Blood was drawn hourly from 0530 or 0630 until 1130. Plasma ghrelin, leptin, and insulin levels were measured by radioimmunoassay. SETTING: Medical Research Institute, Pusan National University Hospital, Korea. SUBJECTS: A total of 16 healthy volunteers. RESULTS: The mean plasma ghrelin level in subjects consuming breakfast was 548.7 +/- 239.6 fmol/ml before breakfast and 384.8 +/- 168.7 fmol/ml 1 h after breakfast, with leptin levels of 6.8 +/- 2.6 and 6.5 +/- 2.5 ng/ml, respectively. Plasma ghrelin levels were lowest 1 h after the meal, although the breakfast times differed. The plasma ghrelin level was lowest at 0730 in subjects not eating breakfast. CONCLUSIONS: These findings suggest that the plasma ghrelin levels are lowest 1 h after breakfast despite the variance in breakfast times. This timing might best reflect an individual's plasma ghrelin level and enable reasonable comparisons.

The ADDITION study: proposed trial of the cost-effectiveness of an intensive multifactorial intervention on morbidity and mortality among people with Type 2 diabetes detected by screening.

OBJECTIVE: The overall aims of the ADDITION study are to evaluate whether screening for prevalent undiagnosed Type 2 diabetes is feasible, and whether subsequent optimised intensive treatment of diabetes, and associated risk factors, is feasible and beneficial. DESIGN: Population-based screening in three European countries followed by an open, randomised controlled trial. SUBJECTS AND METHODS: People aged 40-69 y in the community, without known diabetes, will be offered a random capillary blood glucose screening test by their primary care physicians, followed, if equal to or greater than 5.5 mmol/l, by fasting and 2-h post-glucose-challenge blood glucose measurements. Three thousand newly diagnosed patients will subsequently receive conventional treatment (according to current national guidelines) or intensive multifactorial treatment (lifestyle advice, prescription of aspirin and ACE-inhibitors, in addition to protocol-driven tight control of blood glucose, blood pressure and cholesterol). Patients allocated to intensive treatment will be further randomised to centre-specific interventions to motivate adherence to lifestyle changes and medication. Duration of follow-up is planned for 5 y. Endpoints will include mortality, macrovascular and microvascular complications, patient health status and satisfaction, process-of-care indicators and costs.

Educational campaign to improve the prevention of postoperative venous thromboembolism.

BACKGROUND: Recent studies have revealed considerable scope for improvement in preventing postoperative venous thromboembolism. This project comprised a baseline assessment of the use of preventive measures within the Royal Hobart Hospital, followed by the implementation and evaluation of an educational program directed at hospital staff. AIM: To determine whether the Royal Hobart Hospital's guidelines for the prophylaxis of postoperative venous thromboembolism were being utilized effectively and, if necessary, attempt to improve use of the guidelines through an educational programme. METHODS: Data were collected retrospectively from the medical records of 250 surgical patients undergoing a procedure during February 1997. Patients were classified as being at a low, medium or high risk of venous thromboembolism using two sets of criteria. The percentage of patients receiving the appropriate prophylaxis was determined. An educational programme to promote the hospital's guidelines for the prophylaxis of postoperative venous thromboembolism was then implemented. Included were presentations to staff, posters placed throughout the hospital and the wide distribution of the results and a glossy card showing the hospital's guidelines. Follow-up data were subsequently collected from another 250 surgical patients. RESULTS: Only 59% of patients received appropriate prophylaxis according to the hospital's approved guidelines, with little change when those patients with possible contraindications to thromboprophylaxis were excluded. When those patients at a high risk of venous thromboembolism were examined, only 25% were prescribed the recommended preventive measures. There was no difference between elective versus emergency surgery and the use of appropriate prophylaxis. Following the implementation of the educational programme, data collection from another 250 surgical patients revealed a significant increase (P < 0.05 by chi-square test) in the level of appropriate thromboprophylaxis to 70% of patients, with 77% of the high-risk patients being prescribed the recommended preventive measures. CONCLUSIONS: A pharmacy-based educational intervention significantly improved adherence to the hospital's guidelines for the prophylaxis of postoperative venous thromboembolism.

Exercise training for rehabilitation and secondary prevention of falls in geriatric patients with a history of injurious falls.

OBJECTIVE: To determine the safety and efficacy of an exercise protocol designed to improve strength, mobility, and balance and to reduce subsequent falls in geriatric patients with a history of injurious falls. DESIGN: A randomized controlled 3-month intervention trial, with an additional 3-month follow-up. SETTING: Out-patient geriatric rehabilitation unit. PARTICIPANTS: Fifty-seven female geriatric patients (mean age 82 +/- 4.8 years; range 75-90) admitted to acute care or inpatient rehabilitation with a history of recurrent or injurious falls including patients with acute fall-related fracture. INTERVENTION: Ambulatory training of strength, functional performance, and balance 3 times per week for 3 months. Patients of the control group attended a placebo group 3 times a week for 3 months. Both groups received an identical physiotherapeutic treatment 2 times a week, in which strengthening and balance training were excluded. MEASUREMENTS: Strength, functional ability, motor function, psychological parameters, and fall rates were assessed by standardized protocols at the beginning (T1) and the end (T2) of intervention. Patients were followed up for 3 months after the intervention (T3). RESULTS: No training-related medical problems occurred in the study group. Forty-five patients (79%) completed all assessments after the intervention and follow-up period. Adherence was excellent in both groups (intervention 85.4 +/- 27.8% vs control 84.2 +/- 29.3%). The patients in the intervention group increased strength, functional motor performance, and balance significantly. Fall-related behavioral and emotional restrictions were reduced significantly. Improvements persisted during the 3-month follow-up with only moderate losses. For patients of the control group, no change in strength, functional performance, or emotional status could be documented during intervention and follow-up. Fall incidence was reduced nonsignificantly by 25% in the intervention group compared with the control group (RR:0.753 CI:0.455-1.245). CONCLUSIONS: Progressive resistance training and progressive functional training are safe and effective methods of increasing strength and functional performance and reducing fall-related behavioral and emotional restrictions during ambulant rehabilitation in frail, high-risk geriatric patients with a history of injurious falls.

Exercise and mental health: it's just not psychology!

Exercise has been suggested as an effective adjunctive treatment for a range of mental health conditions. In this study, we explored the perceptions of exercise held by course directors of doctoral training programmes in clinical psychology in England. Given the exploratory nature of the study, we used a qualitative design incorporating semi-structured interviews. Although most participants held favourable attitudes regarding exercise, this was related more to exercise being seen as a positive lifestyle activity that is worth encouraging, rather than exercise being recommended as an adjunctive treatment for mental health problems. Inductive analysis identified four themes that underpinned such a response: inconsistent positions on the evidential criteria used to evaluate the role of exercise, which masked themes regarding the perceived 'simplicity' of exercise interventions, a practical adherence to a mind-body dichotomy, and the incompatibility of exercise with traditional models of understanding and treating clinical conditions. The barriers we have highlighted will continue to hinder the consideration of exercise as a common therapeutic adjunct at present. Although further research is required to examine the relationship between exercise and mental health, consideration must also be given to how such research should be disseminated to mental health professionals.
