Kristi Abram; Helgi Silm; Marje Oona

Data about the prevalence of rosacea are scarce. The aim of this study was to evaluate the prevalence rate of rosacea according to the American National Rosacea Society Expert Committee (NRSEC) classification. A cross-sectional study of 348 subjects randomly selected from a working population >or= 30 years of age was performed. All subjects completed a questionnaire. Skin status was examined according to NRSEC criteria. Of the 348 subjects, 78 (22%) had one or more primary features of rosacea. The most common features were erythema (21%) and telangiectasia (18%). Of the subjects with rosacea, 78% had erythematotelangiectatic rosacea and 22% had papulopustular rosacea. Fifteen percent of the study subjects had experienced frequent episodes of flushing without permanent features of rosacea. No significant gender-related differences were found between study groups. In conclusion, according to the NRSEC, rosacea is a more common skin condition over the age of 30 years than previously thought.

Background.  The prevalence of Helicobacter pylori infection is inversely associated with socioeconomic conditions in childhood. In Estonia, a high prevalence of H. pylori infection has been observed among children born in 1987 and earlier. Since 1991, after the dissolution of the USSR, profound social and economic changes have taken place in the country. The aim of the study was to evaluate changes in the seroprevalence of H. pylori infection among children in the period 1991–2002.

Objective To evaluate Helicobacter pylori and CagA seropositivity in a non‐selected group of schoolchildren in southern Estonia, with reference to previous studies where high seroprevalence to H. pylori (87%) and anti‐CagA positivity (63%) in an adult population from the same region were found. Study population A total of 421 schoolchildren selected haphazardly from a random population (n = 1018, ages 9, 12 or 15 years) and living in urban or rural areas. Methods H. pylori status was determined by evaluation of IgG antibodies against cell surface proteins of H. pylori, strain CCUG 17874, using standard ELISA. Anti‐CagA IgGs were determined by ELISA using a recombinant fragment of CagA (CCUG 17874) as solid‐phase antigen. Absorbance values > 0.3 (405 nm) were taken as a CagA‐positive result based on a study of 25 sera from H. pylori‐negative children. Results Of the 421 subjects, 235 (56%) were H. pylori‐ELISA positive, and 109 out of the 235 (46%) were anti‐CagA positive. Neither H. pylori nor CagA positivity were significantly different in girls and boys, or in children aged 9, 12 or 15 years. The H. pylori prevalence rate (118/181, 65%) as well as CagA positivity (64/181, 35%) in rural areas were higher compared with those in towns (117/240, 49% and 54/240, 22%, respectively; P = 0.001 and P = 0.005). Conclusion Of schoolchildren living in southern Estonia, 56% were seropositive to H. pylori. Half of them had anti‐CagA antibodies. Schoolchildren living in rural areas were infected significantly more often with CagA‐seropositive strains compared with those living in towns. Eur J Gastroenterol Hepatol 12:97‐101

Subjective disease perception and symptoms of depression in relation to healthcare-seeking behaviour in patients with rosacea.

Kristi Abram; Helgi Silm; Heidi-Ingrid Maaroos; Marje Oona

Many patients with rosacea do not seek medical care. The aim of this study was to find predictors for healthcare-seeking behaviour among patients with rosacea. The study subjects were 70 consecutive patients attending a dermatologist (seekers) and 56 subjects with rosacea symptoms selected randomly from among the working population (non-seekers). All subjects completed an Estonian Mood Scale questionnaire, a screening instrument for depressive symptoms, and evaluated their subjective disease perception on a visual analogue scale (VAS). Multivariate analysis showed that the independent predictors for healthcare-seeking behaviour were VAS scores >5 and the presence of advanced forms of rosacea. Higher mean VAS scores were not related to severity of rosacea, but were associated with the presence of depressive symptoms among seekers. In conclusion, healthcare-seeking behaviour is associated with higher subjective disease perception. The presence of depressive symptoms is not related to severity of the disease, but to the subjective disease perception of rosacea patients.

BACKGROUND AND AIMS Despite high immunisation coverage and frequent booster doses, the national notification rates of pertussis in Estonia have been increasing. The peak of 97/100,000 was reached in 2010 which is the highest incidence rate since 1962 (210/100,000). We aimed to measure the prevalence of pertussis toxin (PT) IgG type antibodies in subjects of <18 years and to estimate the pertussis infection activity in a recently non-immunised cohort. METHODS In a cross-sectional serosurvey, all consecutive leftover sera were collected in the Tartu University Hospital during April-August 2012. Anti-PT IgG concentration was measured by commercial ELISA and analysed in yearly cohorts. The antibody concentrations ≥62.5 IU/mL was considered suggestive to pertussis in the last year among 9- to 14-year-olds. RESULTS The GMC of the anti-PT-IgG was 7.4 IU/mL (95% CI 6.9-8.0). In the total of 1053 serum samples, the highest proportion of sera with high antibody titres ≥125 IU/mL and ≥62.5 IU/mL were at the ages when pertussis vaccine boosters were given: 7 years 10.9% (95% CI 4.1-22.3) and 2 years 36.9% (95% CI 25.3-49.8), respectively. Approximately half of all sera had undetectable anti-PT IgG levels. The estimated incidence of Bordetella pertussis infection among 9- to 14-year-olds in the year before serum sampling was 6.3% (95% CI 3.3-10.8), which is at least 60 times higher than the officially reported incidence of pertussis disease in respective years. CONCLUSIONS The serologic method is not suitable for diagnosing pertussis in instances when the last pertussis immunisation was less than one year ago. The relatively high proportion of subjects with undetectable anti-PT IgG levels and the relatively low rate of officially reported pertussis cases suggest that low antibody levels do not necessarily indicate the absence of protection. The estimated incidence rate of pertussis is much higher than officially reported figures, which suggests that asymptomatic/mild B. pertussis infection remains unrecognised and unreported.

OBJECTIVES Rates of pertussis immunisation among children in Estonia are high (∼95%), but pertussis is still the most common vaccine preventable childhood disease. Adults are suspected to be sources of pertussis in children. We aimed to measure pertussis toxin (PT) IgG in adults to estimate pertussis infection activity and compare estimated and reported pertussis incidences. METHODS In a cross-sectional serosurvey, consecutive leftover blood sera (n=3327) from subjects aged 20-99 years old were collected at Quattromed HTI laboratories between the 7th January and 27th February 2013. Anti-PT IgG concentration was measured by ELISA (Euroimmun, Lübeck, Germany). Estimated annual pertussis incidence was calculated for 10-year age classes using de Melker et al. (2006. J Infect. 53(2):106-13) formula. RESULTS The mean number of samples in each 10-year age class was 466 (SD 20.5), except for 90-99 year olds which contained 65 samples. More than half of all subjects (58.1%) had anti-PT IgG <5.0IU/mL, 2.7% had 62.5 to <125IU/mL and 0.6% ≥125IU/mL; no differences occurred between 10-year age classes. Estimated incidence of pertussis infection was 5.8% (95% CI 4.8-7.0) in 2012, with peaks observed in 20-29 year olds (11.0%; 95% CI 7.4-15.6) and 90-99 year olds (10.8%; 95% CI 3.0-26.2). Estimated pertussis incidence rate was 915 times higher than reported. Of 80 subjects with anti-PT IgG ≥62.5IU/mL, 25 (31.3%) had complained of coughing to their GP during the previous six months. CONCLUSION The frequency of pertussis infection was similar for all ages, suggesting similar Bordetella pertussis activity in adults and children. The wide gap between reported and estimated incidence indicates poor recognition of pertussis, likely owing to it being an asymptomatic or mild disease.

Background: Political and public health leaders increasingly recognize the need to take urgent action to address the problem of chronic diseases and multi-morbidity. European countries are facing unprecedented demand to find new ways to deliver care to improve patient-centredness and personalization, and to avoid unnecessary time in hospitals. People-centred and integrated care has become a central part of policy initiatives to improve the access, quality, continuity, effectiveness and sustainability of healthcare systems and are thus preconditions for the economic sustainability of the EU health and social care systems. Purpose: This study presents an overview of lessons learned and critical success factors to policy making on integrated care based on findings from the EU FP-7 Project Integrate, a literature review, other EU projects with relevance to this study, a number of best practices on integrated care and our own experiences with research and policy making in integrated care at the national and international level. Results: Seven lessons learned and critical success factors to policy making on integrated care were identified. Conclusion: The lessons learned and critical success factors to policy making on integrated care show that a comprehensive systems perspective should guide the development of integrated care towards better health practices, education, research and policy.

Abstract Background: Patients with type 2 diabetes reveal different obstacles in living with the disease. The EGPRN initiated a qualitative research EUROBSTACLE to create a broadly conceptualized diabetes-related quality of life (DR-QoL) instrument. It led to the development of the diabetes obstacle questionnaire (DOQ), a five-point Likert-scaled measure, consisting of 78 items in eight scales. Objectives: To develop and validate a short, easy-to-use version of the DOQ. Methods: A cross-sectional study with the DOQ was carried out. Participants answered the DOQ and GPs added some clinical data from their medical records. Data of 853 patients from Belgium, France, Estonia, Serbia, Slovenia, and Turkey were included in the analysis. The selection of items for the short version of the DOQ was achieved with exploratory factor analysis (EFA). Construct validity was proved with EFA and Pearson correlations between the DOQ and the new DOQ-30. Internal reliability was established with Cronbach’s alpha. Results: DOQ-30 resulted in 30 items in nine subscales. It explained 49.8% of items’ variance. It shows a considerable good internal reliability and construct validity. Conclusion: The DOQ-30 is a five-point Likert-scaled broadly conceptualized measure of DR-QoL. It addresses a variety of obstacles, such as social, psychological, cognitive and behavioural. The DOQ-30 is ready for implementation in general practice and research in Europe as a valuable instrument to assess DR-QoL.

Patient Involvement in Geriatric Care – Results and Experiences from a Mixed Models Design Study within Project INTEGRATE

Joern Kiselev; Kadri Suija; Marje Oona; Eva Mellenthin; Elisabeth Steinhagen-Thiessen

Introduction: Patient involvement is a core component of an integrated care approach. While the benefits and prerequisites of patient involvement have been described in general and additionally for some target populations, little is known about the views and experiences of older people regarding this matter. Methods: A study with a mixed-methods design was conducted to gain a better understanding about patient involvement in geriatric care. A questionnaire on shared decision-making was administered within a group of older adults in Germany. Additionally, 7 focus groups with health professionals and geriatric patients in Germany and Estonia were held to deepen the insight of the questionnaire and discussing experiences and barriers of patient involvement. Results: Older people without an actual medical problem expressed a significantly higher desire to participate in shared decisions than those requiring actual medical care. No significant differences could be found for the desire to be informed as part of the care process. No correlation between patients’ desire and experiences on shared decision-making could be observed. In the focus groups, patients demanded a comprehensive and understandable information and education process while the health professionals’ view was very task-specific. This conflict led to a loss of trust by the patients. Conclusions: There is a gap between patients’ and health professionals’ views on patient involvement in older people. The involvement process should therefore be comprehensive and should take into account different levels of health literacy.
