Internet information and medical consultations: experiences from patients' and physicians' perspectives

OBJECTIVE: Many patients use the Internet to obtain health-related information. It is assumed that health-related Internet information (HRII) will change the consultation practice of physicians. This article explores the strategies, benefits and difficulties from the patients' and physicians' perspective. METHODS: Semi-structured interviews were conducted independently with 32 patients and 20 physicians. Data collection, processing and analysis followed the core principles of Grounded Theory. RESULTS: Patients experienced difficulties in the interpretation of the personal relevance and the meaning of HRII. Therefore they relied on their physicians' interpretation and contextualisation of this information. Discussing patients' concerns and answering patients' questions were important elements of successful consultations with Internet-informed patients to achieve clarity, orientation and certainty. Discussing HRII with patients was appreciated by most of the physicians but misleading interpretations by patients and contrary views compared to physicians caused conflicts during consultations. CONCLUSION: HRII is a valuable source of knowledge for an increasing number of patients. Patients use the consultation to increase their understanding of health and illness. Determinants such as a patient-centred consultation and timely resources are decisive for a successful, empowering consultation with Internet-informed patients. PRACTICAL IMPLICATIONS: If HRII is routinely integrated in the anamnestic interview as a new source of knowledge, the Internet can be used as a link between physicians' expertise and patient knowledge. The critical appraisal of HRII during the consultation is becoming a new field of work for physicians.

Gender differences in cardiac rehabilitation outcomes: do women benefit equally in psychological health?

BACKGROUND: Psychological factors are important in the etiology and prognosis of coronary heart disease (CHD). Cardiac rehabilitation (CR) aims to reduce psychological distress, besides other somatic risk factors. Studies have shown that CR is effective in reducing psychological distress, but little is known about gender-specific outcome differences. Our objective was to examine whether women and men benefit equally from outpatient CR in terms of reduction in psychological distress and whether women show more impaired psychological health at baseline of CR than do men. METHODS: We enrolled 441 CHD patients (mean age 58+/-11 years, 79.8% men) who underwent a 12-week outpatient CR program. Psychological dimensions, namely, anxiety, depression, vital exhaustion, social inhibition, and negative affect, were assessed at baseline and post-CR. Multivariate analysis of variance (MANOVA), controlling for age, disease severity, and exercise capacity, was applied to test for gender-specific differences at baseline and change between baseline and post-CR. In addition, gender-specific effect sizes were calculated for the change on psychological dimensions. RESULTS: Women and men did not differ on any psychological measure at baseline of CR. The effect sizes show small to moderate treatment effects on the psychological dimensions assessed. Gender had a significant impact on change on the dimensions vital exhaustion (F=5.040(df=1), p<0.05) and social inhibition (F=5.74(df=1), p<0.05). Women showed larger change on social inhibition and smaller change on vital exhaustion than men. CONCLUSIONS: Women and men do not differ in the extent of psychological distress at baseline of CR, which could be explained also by the exclusion of highly distressed women from treatment. CR is less effective among women with regard to vital exhaustion and more effective with regard to social inhibition compared with men in a sample of low distressed patients.

Relation of heart rate recovery to psychological distress and quality of life in patients with chronic heart failure

BACKGROUND: Psychological distress, poor disease-specific quality of life (QoL), and reduction in vagally mediated early heart rate recovery (HRR) after exercise, all previously predicted morbidity and mortality in patients with chronic heart failure (CHF). We hypothesized lower HRR with greater psychological distress and poorer QoL in CHF. DESIGN: All assessments were made at the beginning of a comprehensive cardiac outpatient rehabilitation intervention program. METHODS: Fifty-six CHF patients (mean 58+/-12 years, 84% men) completed the Hospital Anxiety and Depression Scale and the Minnesota Living With Heart Failure Questionnaire. HRR was determined as the difference between HR at the end of exercise and 1 min after exercise termination (HRR-1). RESULTS: Elevated levels of anxiety symptoms (P=0.005) as well as decreased levels of the Minnesota Living With Heart Failure Questionnaire total (P = 0.025), physical (P=0.026), and emotional (P=0.017) QoL were independently associated with blunted HRR-1. Anxiety, total, physical, and emotional QoL explained 11.4, 8, 7.8, and 9.0%, respectively, of the variance after controlling for covariates. Depressed mood was not associated with HRR-1 (P=0.20). CONCLUSION: Increased psychological distress with regard to elevated anxiety symptoms and impaired QoL were independent correlates of reduced HRR-1 in patients with CHF. Reduced vagal tone might explain part of the adverse clinical outcome previously observed in CHF patients in relation to psychological distress and poor disease-specific QoL.

Heart rate recovery after exercise in chronic heart failure: Role of vital exhaustion and type D personality

OBJECTIVE: Vital exhaustion and type D personality previously predicted mortality and cardiac events in patients with chronic heart failure (CHF). Reduced heart rate recovery (HRR) also predicts morbidity and mortality in CHF. We hypothesized that elevated levels of vital exhaustion and type D personality are both associated with decreased HRR. METHODS: Fifty-one patients with CHF (mean age 58+/-12 years, 82% men) and left ventricular ejection fraction (LVEF)

The efficacy of psychological interventions for infertile patients: a meta-analysis examining mental health and pregnancy rate

BACKGROUND: Psychological interventions for infertile patients seek to improve mental health and increase pregnancy rates. The aim of the present meta-analysis was to examine if psychological interventions improve mental health and pregnancy rate among infertile patients. Thus, controlled studies were pooled investigating psychological interventions following the introduction of assisted reproductive treatments (ART). METHODS: The databases of Medline, PsycINFO, PSYNDEX, Web of Science and the Cochrane Library were searched to identify relevant articles published between 1978 and 2007 (384 articles). Included were prospective intervention studies on infertile patients (women and men) receiving psychological interventions independent of actual medical treatment. The outcome measures were mental health and pregnancy rate. A total of 21 controlled studies were ultimately included in a meta-analysis comparing the efficacy of psychological interventions. Effect sizes (ES) were calculated for psychological measures and risk ratios (RR) for pregnancy rate. RESULTS: The findings from controlled studies indicated no significant effect for psychological interventions regarding mental health (depression: ES 0.02, 99% CI: -0.19, 0.24; anxiety: ES 0.16, 99% CI: -0.10, 0.42; mental distress: ES 0.08, 99% CI: -0.10, 0.51). Nevertheless, there was evidence for the positive impact of psychological interventions on pregnancy rates (RR 1.42, 99% CI: 1.02, 1.96). Concerning pregnancy rates, significant effects for psychological interventions were only found for couples not receiving ART. CONCLUSIONS: Despite the absence of clinical effects on mental health measures, psychological interventions were found to improve some patients' chances of becoming pregnant. Psychological interventions represent an attractive treatment option, in particular, for infertile patients who are not receiving medical treatment.

[Complementary and alternative medicine in primary care in Switzerland]

OBJECTIVE: This study investigated the current supply of complementary and alternative medicine (CAM) in Swiss primary care. Information was collected on physicians' qualifications in CAM, frequency of patients' demand for CAM, physicians' supply and temporal resources for CAM as well as physicians' referrals to CAM. MATERIAL AND METHODS: 750 (500 German-speaking and 250 French-speaking) randomly selected Swiss female and male primary care physicians were asked to complete a questionnaire (response rate 50.4%). Sociodemographic data on professional training, place of residence, and sex were used to calculate a weighting factor to correct the responders' data in the analysis accordingly. RESULTS: 14.2% of the physicians were qualified in at least one CAM discipline. Around 30% (95% confidence interval 25.4-34.6%) of the physicians were asked for CAM by their patients more than once a week. Homeopathy and phytotherapy were the most frequently offered therapies, followed by traditional Chinese medicine (TCM)/acupuncture. 62.5% (57.6-67.4%) of the physicians refer their patients to CAM. Most patients were referred to TCM/acupuncture. Of the 37.2% (32.6-42.4%) of the physicians who do not refer their patients to CAM, around 40% (35.1-44.9%) offer it themselves. CONCLUSION: About three quarters of the physicians offer CAM themselves or refer their patients to CAM treatments. CAM is very important in primary medical care in Switzerland. Clear regulations for CAM are required in order to ensure a high quality in care.

Low Mannan-binding lectin serum levels are associated with complicated Crohn's disease and reactivity to oligomannan (ASCA)

OBJECTIVES: Mannan-binding lectin (MBL) acts as a pattern-recognition molecule directed against oligomannan, which is part of the cell wall of yeasts and various bacteria. We have previously shown an association between MBL deficiency and anti-Saccharomyces cerevisiae mannan antibody (ASCA) positivity. This study aims at evaluating whether MBL deficiency is associated with distinct Crohn's disease (CD) phenotypes. METHODS: Serum concentrations of MBL and ASCA were measured using ELISA (enzyme-linked immunosorbent assay) in 427 patients with CD, 70 with ulcerative colitis, and 76 healthy controls. CD phenotypes were grouped according to the Montreal Classification as follows: non-stricturing, non-penetrating (B1, n=182), stricturing (B2, n=113), penetrating (B3, n=67), and perianal disease (p, n=65). MBL was classified as deficient (<100 ng/ml), low (100-500 ng/ml), and normal (500 ng/ml). RESULTS: Mean MBL was lower in B2 and B3 CD patients (1,503+/-1,358 ng/ml) compared with that in B1 phenotypes (1,909+/-1,392 ng/ml, P=0.013). B2 and B3 patients more frequently had low or deficient MBL and ASCA positivity compared with B1 patients (P=0.004 and P<0.001). Mean MBL was lower in ASCA-positive CD patients (1,562+/-1,319 ng/ml) compared with that in ASCA-negative CD patients (1,871+/-1,320 ng/ml, P=0.038). In multivariate logistic regression modeling, low or deficient MBL was associated significantly with B1 (negative association), complicated disease (B2+B3), and ASCA. MBL levels did not correlate with disease duration. CONCLUSIONS: Low or deficient MBL serum levels are significantly associated with complicated (stricturing and penetrating) CD phenotypes but are negatively associated with the non-stricturing, non-penetrating group. Furthermore, CD patients with low or deficient MBL are significantly more often ASCA positive, possibly reflecting delayed clearance of oligomannan-containing microorganisms by the innate immune system in the absence of MBL.

Kindesmisshandlung: Behandlung von psychischen Störungen im Zusammenhang mit Gewalt an Kindern

Auszug Im November 2006 stellten die Vereinten Nationen (UN) den jüngsten von einem unabhängigen Experten erstellten internationalen Bericht zu Gewalt an Kindern vor, wonach im Jahre 2002 weltweit schätzungsweise 53.000 Kinder durch Totschlag starben sowie 150 Mio. Mädchen und 73 Mio. Jungen unter 18 Jahren Opfer sexueller Misshandlungen wurden. In 31 von 200 Staaten sind körperliche Strafen von Auspeitschen bis Amputationen erlaubt und in knapp der Hälfte der Staaten ist die Körperstrafe an Schulen erlaubt (Pinheiro 2006). In Deutschland und Großbritannien sterben pro Woche zwei, in Frankreich drei, in Japan vier und in USA 27 Kinder an Misshandlung und Vernachlässigung. In einer vorangegangen Studie der UNICEF, dem Kinderhilfswerk der Vereinten Nationen, wurde festgestellt, dass in den reichen Ländern auf 100.000 Kinder jährlich zwischen 0, 1 und 3, 7 Kinder unter 15 Jahren als Folge von Misshandlung oder Vernachlässigung sterben (⊡ Abb. 48.1 ). Schätzungen gehen davon aus, dass auf einen Todesfall rund 150 Fälle von Kindesmisshandlung ohne Todesfolge kommen (UNICEF 2003).
