[Epidemiology of polypharmacy in primary healthcare in the Reykjavik metropolitan area 2010-2019].

INTRODUCTION: Taking medicines can induce risks leading to negative health issues that can grow in accordance with the number of medicines used. Many studies on the prevalence of polypharmacy have been carried out in other countries, but such studies are lacking in Iceland. The aim of this study was to analyse the prevalence of polypharmacy in primary care in the Reykjavik metropolitan area. METHODS: The study population consisted of individuals who had been prescribed five or more drugs by physicians in primary care in the Reykjavik metropolitan area during the study period. Data was collected on all drug prescriptions for individuals in the area. Those who had five or more drugs prescribed in the primary healthcare database from 1 January 2010 through 31 December 2019 were included in the study. According to Statistics Iceland, the total number of inhabitants in the area was 200.907 in 2010 and 228.222 in 2019. FINDINGS: The prevalence of polypharmacy increased gradually in 2010-2019, or by 37.9% during this period. Patients with polypharmacy were 9.8% (19.778) at the beginning of the study in 2010 and increased to 13.6% (30.970) in 2019. A clear association was observed between age and polypharmacy, and the study showed polypharmacy to be more common among women. The study findings revealed that the greatest relative increase in polypharmacy was among young people from 20-49 years of age. ATC class analysis showed a sharp increase in the first and third levels of the ATC subgroups. CONCLUSION: The findings suggest polypharmacy to be common in the Reykjavik metropolitan area. Similarly, its prevalence seems to be increasing in younger patients. It is important to gain a better understanding of the reasons for the development of polypharmacy and evaluate the increasing medicalisation in society. The underlying reasons, as well as the effects of polypharmacy, can lead to both positive and negative health outcomes.

[Hypertension Management in Primary Care in the Capital Area of Iceland].

INTRODUCTION: High blood pressure (HT) is one of the main risk factors for cardiovascular diseases which in 2010 caused one third of all mortality in the world. Untreated, HT can cause stroke, myocardial infarction, heart failure, dementia, kidney failure, atherosclerosis and eye diseases. The main aim of this study was to find out how HT is treated in primary care in the capital area of Iceland. MATERIAL AND METHODS: The study is a descriptive retrospective cross-sectional study covering the years 2010, 2014 and 2019. Information about all patients over 18 years old diagnosed with HT were gathered from computerised medical records at every primary care center in the Capital area. RESULTS: The number of individuals diagnosed with HT increased during the study period and the mean age did also increase. The sex ratio changed with more men diagnosed than women. Of 25.873 patients diagnosed with HT in the year 2010, 63.4% received drug treatment. In 2019 this percentage had dropped 60.9% (p<0,001). Of those on antihypertensive drug treatment the proportion receiving one, two or three drugs remained same from 2010-2019. The most common group of drugs used were diuretics (C03), beta-blockers (C07), calcium channel blockers (C08) and renin-angiotensin-aldosteron-system (RAAS) inhibitors (C09). The proportion af these drug groups changed significantly during the study. Fever patients were treated by diuretics (p<0,001) or beta-blockers ((p<0,001) but the number treated by calcium channel blockers (p<0,01) or RAAS inhibitors increased (p<0,001). During the whole stud period 44.1% of the patients reached the target goals. The proportion of patients who reached the target goals in different health care center was specifically for the year 2019. Just over 41% of HT patients reached the targets goals. However, two health care centers achieved notably different results with only one third of the patients attaining the goals. CONCLUSION: As has recently been shown in epidemiologic studies hypertension in Iceland is both underdiagnosed and undertreated although the country ranks high on both counts in international comparison. Furthermore, the fact that under half of hypertensive patients in general practice in the capital area reach the targeted treatment goals, cannot be considered an acceptable. Thus, it is of immense importance to improve both the diagnosis and the treatment of HT.

Encouraging rational antibiotic prescribing behaviour in primary care - prescribing practice among children aged 0-4 years 2016-2018: an observational study.

OBJECTIVE: To study antibiotic prescriptions among 0- to 4-year-old children before and after implementing a quality project on prudent prescribing of antibiotics in primary healthcare in the capital region of Iceland. DESIGN: An observational, descriptive, retrospective study using quantitative methodology. SETTING: Primary healthcare in the Reykjavik area with a total population of approximately 220,000. SUBJECTS: A total of 6420 children 0-4 years of age presenting at the primary healthcare centres in the metropolitan area over three years from 2016 to 2018. MAIN OUTCOME MEASURES: Reduction of antibiotic prescriptions and change in antibiotic profile. Data on antibiotic prescriptions for children 0-4 years of age was obtained from the medical records. Out-of-hours prescriptions were not included in the database. RESULTS: The number of prescriptions during the study period ranged from 263.6 to 289.6 prescriptions/1000 inhabitants/year. A reduction of 9% in the total number of prescriptions between 2017-2018 was observed. More than half of all prescriptions were for otitis media, followed by pneumonia and skin infections. Amoxicillin accounted for over half of all prescriptions, increasing between 2016 and 2018 by 51.3%. During this period, the prescribing of co-amoxiclav and macrolides decreased by 52.3% and 40.7%, respectively. These changes were significant in all cases, p < 0.0001. CONCLUSION: The results show an overall decrease in antibiotic prescribing concurrent with a change in the choice of antibiotics prescribed and in line with the recommendations presented in the prescribing guidelines implemented by the Primary Healthcare of the Capital Area, and consistent with the project's goals.Key pointsA substantial proportion of antibiotic prescribing can be considered inappropriate and the antibiotic prescription rate is highest in Iceland of the Nordic countries.After implementing guidance on the treatment of common infections together with feedback on antibiotic prescribing, a decrease in the total number of prescriptions accompanied by a shift in the antibiotic profile was observed.

[Factors affecting general practitioners' choice of drug therapy: A study in primary healthcare in Iceland].

INTRODUCTION: This study aimed to analyse several factors that influence the decision-making of primary care physicians in Iceland in their choice of drug therapy for their patients. Also, to find which factors can act as a hindrance in making the best choices. Finally, to analyse which elements could be most important in facilitating decisions. MATERIAL AND METHODS: A questionnaire was sent by e-mail to physicians working in primary care in Iceland. The questionnaire comprised closed questions, open text boxes, and ranking questions. The data was processed and analysed using Microsoft Excel. RESULTS: The total number of primary care physicians who responded to the questionnaire was 93, a response rate of 40.7% of all the primary care physicians. The results reveal that physicians working in primary care consider clinical guidelines, the Icelandic National Formulary, and personal experience to be the most important factors when choosing a medication. Primary care physicians strongly agree that the lack of drug interaction software connected to medical records is a shortcoming. The most important factors that need improvement to facilitate primary care physicians' decision-making are drug formularies and interaction software. CONCLUSION: The results suggest some factors that support physicians in primary care in making decisions when choosing drug therapy, such as a drug formulary, drug interaction software, information about patients' drug therapy, variable length in face-to-face consultations, evidence based information on new drugs, and counselling provided by clinical pharmacists.

[Changes in prescriptions on opioids in primary health care during the years 2008-2017].

INTRODUCTION: In recent decades there has been a notable increase in the prescription of opioids in western countries. With this rise in use of opioids the risk of side effects, opioid abuse and deaths linked to opioids have become more apparent. The increase in opioid prescription may partly stem from a change in attitude in relation to pain management. Research has shown that pain is among the most common reasons people seek medical care and chronic pain is prevalent. Iceland is leading the Nordic countries in opioid prescriptions. OBJECTIVE: To examine prescriptions of opioids in primary car in Iceland for all age group from 2008 to 2017. METHODS: The research included all opioid prescription in every health clinic in the capital area in Iceland the between 2008 and 2017. Population in the capital area in this time period was between 201 and 222 thousand people. Data was collected from medical records database of the primary health care and approximatley 68.000 individuals had received a prescription for opioids during the research period. RESULTS: During the research period there was a 17,2% (p<0,01) increase in DDD/1000 inhabitants/day (Defined daily dose) for opioids. About a third of those who got the prescription were men and that ratio did not change during the period. proportionately, the biggest change in DDD/1000 inhabitants/day was in the age group made of people 90 years old and older, about 40,5% ((p<0,01)). The biggest increase in number of people getting a prescription for opioids was in the age group 30-39, about 25,5% ((p<0,01)). Number of prescriptions increased in every category of opioids, measured in DDD/1000 inhabitants/day,15,3% ((p<0,01)) in parkódin, 20,7% ((p<0,01)) in parkódín forte, 4,7% (p<0,01)) in tramadol and 85,6% (p<0,01) in the strongest opioids. DISCUSSION: the evolution of prescriptions for every type of opioid to the clients of the health clinics in the capital area that occured in the years from 2008 to 2017, proportionately highest for the strongest opioids, should encourage a review of pain treatment within the health clinics and development within that field.

Prescriptions of antibiotics in out-of-hours primary care setting in Reykjavik capital area.

OBJECTIVE: To describe antibiotic prescriptions in out-of-hour (OOH) service in primary care setting in Iceland and to study the indications for prescriptions. DESIGN: A population based retrospective study, using electronic data from the OOH registration system. SETTING: OOH primary care setting in Reykjavik capital area in Iceland. SUBJECTS: All patients that received a prescription for oral antibiotic drug at an OOH service in Reykjavik capital area over a one-year period. MAIN OUTCOME MEASURES: Number of oral antibiotic prescriptions and diagnosis connected to the prescriptions according to age and sex. RESULTS: There were 75,582 contacts with the OOH primary care of which 25,059 contacts resulted in prescription of an oral antibiotic (33%). The most common antibiotic prescribed in total, and for the diagnosis studied, was amoxicillin with clavulanic acid. It was most often prescribed for acute otitis media. Of those diagnosed with otitis media 50% were treated with amoxicillin with clavulanic acid and 40% of those diagnosed with pneumonia received that treatment. The second most prescribed antibiotic was amoxicillin. Most often it was prescribed for sinusitis, in 47% of cases with that diagnosis. CONCLUSION: Antibiotics are often prescribed in OOH primary care in Iceland and a substantial number of the patients diagnosed in OOH primary care with acute otitis media or pneumonia are prescribed broad-spectrum antibiotics. Key points Antibiotic prescription rate is high and broad-spectrum drugs often prescribed in OOH primary care service in Iceland. The results should encourage general practitioners in Iceland to review antibiotic prescriptions in OOH service.

[Antidepressants, anxiolytics and hypnotics prescribed to young adults before and after an economic crisis in Iceland - A cross-sectional study at the Primary Health Care of Reykjavik capital area].

BACKGROUND: According to research findings, the financial crisis hitting Iceland in the autumn of 2008 caused both economic and health-related effects on the Icelandic population. It has been well known that the Icelandic population uses more antidepressants, anxiolytics and hypnotics compared to other Nordic countries. The aim of this research was to study the trend in prescription for these drugs by the Primary Health Care of Reykjavik capital area to young adults, during the years prior to and following the crisis. METHOD: In this cross-sectional study, data were gathered on all medical prescriptions of antidepressants, anxiolytics and hypnotics, prescribed by the Primary Health Care of Reykjavik capital area to people aged 18-35, during 2006-2016. While Reykjavík capital residents in the specified age group were approximately 55 thousand during the research period, this study included data on approximately 23 thousand individuals, received from the Icelandic electronical medical record system "Saga" used by the Primary Health Care. RESULTS: Research results demonstrate a significant average annual increase of prescribed defined daily doses (DDD) for all three medication categories during the research period; 3% (p<0,001) for anxiolytics, 1.6% (p<0,001) for hypnotics and 10.5% (p<0,001) for antidepressants. Between 2008-2009, prescribed daily doses of anxiolytics increased by 22.7% (p<0,001), where a 12.9% (p<0,001) increase was seen for women and 39.5% (p<0,001) increase for men. Of those men who were prescribed anxiolytics in 2009, 35% had no history of such prescriptions the previous year. From 2006-2008 an average annual increase of 13.6% (p<0,001) was seen in prescribed daily doses of hypnotics, whereof 24.4% (p<0,001) increase was seen for men and 7.8% (p<0,001) for women. CONCLUSIONS: This study demonstrates a significant increase in prescribed amount of hypnotics and anxiolytics during the years prior and after the economic crisis, with more prominent results amongst men compared to women. This trend was however not observed for antidepressants, which could suggest an overall tendency towards short- and fast acting drug prescriptions as a treatment for challenging difficult personal circumstances during the economic crisis in Iceland.

[Prescribing physical activity after labour, for women diagnosed with gestational diabetes mellitus].

BACKGROUND: The prevalence of gestational diabetes mellitus (GDM) has been rapidly increasing in Iceland and 19% of women who gave birth at Landspítali - University hospital in 2018 were diagnosed with GDM. Women who develop GDM in pregnancy have an increased risk of recurrence in future pregnancies, as well as an increased risk for developing type 2 diabetes mellitus later in life. Obesity and a sedentary lifestyle are known risk factors for the development of GDM. Prescribing physical activity has become an available treatment option in all Icelandic primary healthcare centres. The aim of this study was to examine the effect of prescribing postpartum exercise for women with a history of GDM on their physical activity level, quality of life, BMI and biochemical markers typical for metabolic syndrome. MATERIALS AND METHODS: Women who delivered from 1st January 2016 to 30th June 2017 and sought prenatal care at healthcare centres within the Primary Health Care of the Capital Area were offered participation in the study. Participants were randomly divided into two groups, with one group being prescribed physical activity for five months while the other group received standard treatment of care. Blood tests (fasting blood sugar, HbA1c, cholesterol and insulin levels), BMI, general activity level and the patient's quality of life were measured at both three and eight months postpartum. RESULTS: 84 women participated, 45 were assigned to the treatment group and 39 to the control group. General activity levels increased significantly in the treatment group, but no significant changes were seen in their blood test values. The treatment suggested an improvement trend in the women's BMI and quality of life, but the results were not significant. Women who breastfed had significantly lower insulin levels than women not breastfeeding. There was a stronger positive correlation between BMI and insulin levels than between fasting blood sugar levels and insulin levels. CONCLUSION: Prescribing physical activity after delivery for women with a history of GDM significantly increased their general activity level and breastfeeding seems to have a lowering effect on insulin levels.

Effectiveness of a partnership-based self-management programme for patients with mild and moderate chronic obstructive pulmonary disease: a pragmatic randomized controlled trial.

AIMS: To evaluate the effectiveness of a 6-month, partnership-based self-management programme for patients with mild and moderate chronic obstructive pulmonary disease. BACKGROUND: Self-management is a widely valued concept used to address contemporary issues of chronic health problems. Findings of self-management programmes for people with chronic obstructive pulmonary disease are inconclusive. DESIGN: Pragmatic randomized control trial. METHODS: Patients, 45-65 years old, with mild and moderate chronic obstructive pulmonary disease were invited with a family member. Experimental group (n = 48) participated in a 6-month, partnership-based self-management programme consisting of: (a) three to four conversations between nurse and patient-family member; (b) 6 months of smoking cessation; and (c) interdisciplinary team-patient-family member group meeting. Control group (n = 52) received usual care. Data were collected at months zero, six and 12. The trial lasted from June 2009-March 2013. RESULTS: Patients with mild and moderate chronic obstructive pulmonary disease who participated in the partnership-based self-management programme perceived less intrusiveness of the disease and its treatment than patients in the control group. Patients in the experimental group did not have better health-related quality of life, less anxiety or depression, increased physical activity, fewer exacerbations or better smoking status than patients in the control group. Patients in both groups found participation in the research useful and important. CONCLUSION: The partnership-based self-management programme had benefits concerning perception of the intrusiveness of chronic obstructive pulmonary disease and its treatment on lifestyles, activities and interests for young patients with the disease in its early stages. High satisfaction in control group, low family attendance and the relatively short treatment period may explain the less than expected benefits of the programme.

Smoking during pregnancy: childbirth and health study in primary care in Iceland.

OBJECTIVE: To study the prevalence and possible predictors for smoking during pregnancy in Iceland. DESIGN: A cross-sectional study. SETTING: Twenty-six primary health care centres in Iceland 2009-2010. SUBJECTS. Women attending antenatal care in the 11th-16th week of pregnancy were invited to participate by convenient consecutive manner, stratified according to residency. A total of 1111 women provided data in this first phase of the cohort study. MAIN OUTCOME MEASURES: Smoking habits before and during early pregnancy were assessed with a postal questionnaire, which also included questions about socio-demographic background, physical and emotional well-being, and use of medications. RESULTS: The prevalence of smoking prior to pregnancy was 20% (223/1111). During early pregnancy, it was 5% (53/1111). In comparison with women who stopped smoking during early pregnancy, those who continued to smoke had on average a significantly lower level of education, had smoked more cigarettes per day before pregnancy, and were more likely to use nicotine replacement therapy in addition to smoking during pregnancy. A higher number of cigarettes consumed per day before pregnancy and a lower level of education were the strongest predictors for continued smoking during pregnancy. CONCLUSION: The majority of Icelandic women who smoke stop when they become pregnant, and the prevalence of smoking during pregnancy in Iceland is still about 5%. Our results indicate stronger nicotine dependence in women who do not stop smoking during pregnancy. Awareness of this can help general practitioners (GPs) and others providing antenatal care to approach these women with more insight and empathy, which might theoretically help them to quit.

How primary healthcare in Iceland swiftly changed its strategy in response to the COVID-19 pandemic.

OBJECTIVE: To describe how the primary healthcare (PHC) in Iceland changed its strategy to handle the COVID-19 pandemic. DESIGN: Descriptive observational study. SETTING: Reykjavik, the capital of Iceland. POPULATION: The Reykjavik area has a total of 233 000 inhabitants. MAIN OUTCOME MEASURES: The number and the mode of consultations carried out. Drug prescriptions and changes in the 10 most common diagnoses made in PHC. Laboratory tests including COVID-19 tests. Average numbers in March and April 2020 compared with the same months in 2018 and 2019. RESULTS: Pragmatic strategies and new tasks were rapidly applied to the clinical work to meet the foreseen healthcare needs caused by the pandemic. The number of daytime consultations increased by 35% or from 780 to 1051/1000 inhabitants (p<0.001) during the study period. Telephone and web-based consultations increased by 127% (p<0.001). The same tendency was observed in out-of-hours services. The number of consultations in maternity and well-child care decreased only by 4% (p=0.003). Changes were seen in the 10 most common diagnoses. Most noteworthy, apart from a high number of COVID-19 suspected disease, was that immunisation, depression, hypothyroidism and lumbago were not among the top 10 diagnoses during the epidemic period. The number of drug prescriptions increased by 10.3% (from 494 to 545 per 1000 inhabitants, p<0.001). The number of prescriptions from telephone and web-based consultations rose by 55.6%. No changes were observed in antibiotics prescriptions. CONCLUSIONS: As the first point of contact in the COVID-19 pandemic, the PHC in Iceland managed to change its strategy swiftly while preserving traditional maternity and well-child care, indicating a very solid PHC with substantial flexibility in its organisation.

[Pharmaceutical Care at the primary care clinic in Garðabær - number and type of drug therapy problems identified among elderly clients].

INTRODUCTION: Elderly people are a rising population in Iceland. With higher age the likelihood of drug consumption increases and thus drug therapy problems. Pharmaceutical care has been established abroad, where the pharmacist works in collaboration with other healthcare professionals to reduce patients' drug therapy problems. The aim of this research was to study the number and types of drug therapy problems of older individuals in primary care in Garðabær, by providing pharmacist-led pharmaceutical care in collaboration with general practitioners. METHODS: Five general practitioners selected patients, 65 years and older, and asked the pharmacist to provide them with pharmaceutical care service. The pharmacist provided pharmaceutical care using a well-defined process. RESULTS: A total of 100 patients participated in the research, 44 men and 56 women. On average the pharmacist identified two drug therapy problems per patient. The most frequent drug therapy problem was related to noncompliance (30.1%), next was adverse drug reaction (26.7%) and the third was unnecessary drug therapy (18.2%). Almost all pharmacist comments were accepted by the general practitioners (90.3%). CONCLUSIONS: Our results reveal that a pharmacist providing pharmaceutical care makes, on average, two comments regarding each drug therapy. In almost all cases the general practitioners accept the comments.

General practitioners' perceptions of the current status and pharmacists' contribution to primary care in Iceland.

Background For the past several years pharmacists' responsibilities have expanded globally from traditional tasks of dispensing medications to collaborating with other health care professionals in patient care. Similar developments have not occurred in outpatient settings in Iceland. Objective The aim of this study was to explore Icelandic general practitioners' views on the current status of primary care, their perceptions of pharmacists as a health care profession, and their attitudes towards future GP-pharmacist collaboration in primary care in Iceland. Setting Twelve primary care clinics in Iceland. Methods Semi-structured in-depth interviews were conducted with general practitioners from different primary care clinics in Iceland. A purposive and snowball sampling technique was used to select participants. All interviews were recorded and transcribed verbatim. The transcripts were categorized by themes and then analyzed using conventional content analysis. Main outcome measure General practitioners' attitudes towards pharmacists. Results Twenty general practitioners from twelve different primary care clinics in Iceland were interviewed. There are several unmet needs regarding medicines and patient monitoring in the Icelandic health care system. General practitioners suggested ways in which these gaps may be addressed and pharmacist-led clinical service was one of the suggestions. Currently, their communication with pharmacists in the primary sector solely surrounds practical non-clinical issues. Due to increasing polypharmacy and multimorbidity, they suggested that pharmacists should be more involved in patient care. Conclusions General practitioners believe that pharmacist-led clinical service can increase the quality of patient therapy. To improve communication between these health care providers, pharmacists must also re-professionalize (strengthening the profession´s status through new responsibilities and tasks), not having a conflict of interest and showing that they have expertise in patient care.

[Diagnosis, treatment and prognosis of community acquired pneumonia - results from three primary care centers in Iceland]. / Greining, medferd og horfur lungnabolgu: nidurstodur fra thremur heilsugaeslustodvum.

AIMS: To study how general practitioners diagnose and treat adult patients with community acquired pneumonia (CAP) and evaluate outcomes. METHOD: Retrospective chart review for one year on patients 18 years and older diagnosed with CAP in three different primary care centers in Iceland. RESULTS: A total of 215 patients were diagnosed with CAP. Of those 195 were both diagnosed and treated in the primary health care and 20 patients were referred for specialized care. Mean age was 50.3 years (SD= 21.0) and 126 (65%) of the patients were women. Most patients had been ill for less than a week and did not have a previously diagnosed lung disease. Cough was the most common symptom (71%) and 96% had abnormal chest auscultation. Vital signs were frequently not recorded. A chest radiograph was done in third of the cases and showed abnormality in over 80%. Most patients (94%) were treated with antibiotics usually extended spectrum penicillin. Phone consultations were the most common form of communication after diagnosis and about 12% of subjects had their antibiotics changed and about 10% had a chest radiograph done after diagnosis had been made. There was no mortality from CAP during the study period. CONCLUSIONS: CAP was diagnosed clinically and managed in primary care in most cases. CAP was more common in women and a minority of patients had underlying lung diseases. Vital sign measurements were used less than expected. Broad spectrum antibiotics were widely used for treatment. CAP had no mortality.

[Prevalence of smoking and chronic obstructive pulmonary disease among patients at the Akureyri Primary Care Center]. / Algengi reykinga og langvinnrar lungnateppu hja skjolstaedingum heilsugaeslustodvarinnar a Akureyri.

INTRODUCTION: Even though smoking has decreased significantly over the last few years, the majority of Icelanders 40 years of age or older have a history of smoking. Limited information is available on respiratory symptoms and diagnosis of chronic obstructive lung diseases (COPD) in this group. MATERIAL AND METHODS: During a four week period at the Akureyri Primary Care Center all individuals above the age of 40 were given a questionnaire on smoking, respiratory symptoms and medical treatment. There were a total of 416 individuals and the response rate was 63%. Spirometry was done on those who had smoked. RESULTS: Of the 259 responders, 150 (57,9%) had a history of smoking. In this group 117 (45,2%) had quit but 33 (12,7%) were still smoking. Of those that had a history of smoking 16% had COPD according to spirometry results and 2/3 did not have a previous diagnosis. Respiratory symptoms were more common with increasing obstruction. Of the smokers 26% had never been advised by a physician to stop smoking. A total of 14,3% of the whole group had a previous diagnosis of emphysema, chronic obstructive pulmonary disease or chronic bronchitis. Altogether 23,5% had previously been diagnosed with asthma, asthmatic bronchitis or allergic bronchitis. CONCLUSION: A history of smoking was common among the primary care patients. One in six who had a smoking history were found to have COPD and the majority were unaware of the diagnosis. Respiratory diagnoses were common. By spirometric evaluation many smokers are diagnosed with previously unknown COPD.

Irritable bowel syndrome: physicians' awareness and patients' experience.

AIM: To study if and how physicians use the irritable bowel syndrome (IBS) diagnostic criteria and to assess treatment strategies in IBS patients. METHODS: A questionnaire was sent to 191 physicians regarding IBS criteria, diagnostic methods and treatment. Furthermore, 94 patients who were diagnosed with IBS underwent telephone interview. RESULTS: A total of 80/191 (41.9%) physicians responded to the survey. Overall, 13 patients were diagnosed monthly with IBS by specialists in gastroenterology (SGs) and 2.5 patients by general practitioners (GPs). All the SGs knew of the criteria to diagnose IBS, as did 46/70 (65.7%) GPs. Seventy-nine percent used the patient's history, 38% used a physical examination, and 38% exclusion of other diseases to diagnose IBS. Only 18/80 (22.5%) physicians used specific IBS criteria. Of the patients interviewed, 59/94 (62.8%) knew they had experienced IBS. Two out of five patients knew IBS and had seen a physician because of IBS symptoms. Half of those received a diagnosis of IBS. A total of 13% were satisfied with treatment. IBS affected daily activities in 43% of cases. CONCLUSION: Half of the patients with IBS who consulted a physician received a diagnosis. Awareness and knowledge of diagnostic criteria for IBS differ between SGs and GPs.

[Prevalence of Streptococcus pyogenes and methicillin-resistant Staphylococcus aureus in the pharynx of healthy children in the town of Gardabaer]. / Algengi Streptococcus pyogenes og methisillín ónaemra Staphylococcus aureus í hálsi heilbrigdra barna í Gardabae.

BACKGROUND: Treating S. pyogenes pharyngitis with antibiotics is recommended after confirming its presence using culture or rapid antigen tests. Limiting unnecessary antibiotics use is important in attempt to avoid rising resistance to drugs such as macrolides. Not all individuals carrying S. pyogenes are infected. OBJECTIVE: To evaluate the carriage rate of S. pyogenes and methicillin resistant S. aureus (MRSA) among healthy children in the Reykjavík capital area. SUBJECTS AND METHODS: Cross-sectional study for the carriage of S. pyogenes and MRSA among healthy children in the town of Gardabaer. The study took place in March and April 2005. Throat cultures were collected from 270 asymptomatic healthy primary school students and cultured selectively for S. pyogenes and MRSA and tested for antimicrobial susceptibilities. RESULTS: Prevalence of S. pyogenes was found to be 22%. The proportion of carriers in 1st to 6th grade was 28%, compared with 11% in 7th to 10th grade students. The highest proportion was in 1st grade, 45%. The proportion S. pyogenes resistant to erythromycin was 17%, to tetracycline 13% and clindamycin 2%. All strains were susceptible to penicillin. No MRSA strains were found. CONCLUSIONS: The study reveals a high S. pyogenes carriage rate in primary school children in Garethabaer. Physicians should consider the prevalence of streptococcal carriage when diagnosing streptococcal pharyngitis in children, and only perform culture and/or antigen tests when clinically indicated.

[Spirometry in a health care center: indications, results and quality.].

OBJECTIVE: Spirometry is important for the diagnosis and treatment of lung diseases. Studies on the use of spirometry in health care centers are few and none in Iceland. The objective of this study was to evaluate the use of spirometry in a single health care center in Iceland in regard to indications, quality and results. MATERIALS AND METHODS: Patients evaluated at the Primary Care Clinic in Garethabaer during a 6 month period were included in the study. Information was collected about the spirometry, indications and treatment given. Spirometry was done by a physican or nurse. All spirometries were evaluated by a pulmonary specialist. The study was approved by the National bioethics committee and Data protection agency. RESULTS: During the study period 63 spirometries were done and majority of them were on the request of one physican. There were 19 males and 44 females and the age distribution was from 17 to 69 years of age. Smokers were 17/63, former smokers were 24 and 20 were non smokers. The most common indication for spirometry was cough in 37/63 and dyspnea in 20/63. No spirometry was done for history of smoking only. Twenty eight patients had abnormal lung auscultation. The quality of the spirometry was sufficient in 54/63. In 24/63 patients the spirometry was normal. Of those with abnormal spirometry 30 had obstruction, 3 had restriction and in 6/63 of cases the results were mixed. CONCLUSION: The study indicates that primary care physicians are underutilizing spirometry for diagnosis of lung diseases.

Medical treatment and secondary prevention of coronary heart disease in general practice in Iceland.

OBJECTIVE: To evaluate the implementation of secondary prevention and treatment of coronary heart disease (CHD) in general practice in Iceland. SETTINGS: Two health care centers adjacent to Reykjavik with a total of 25766 inhabitants. PATIENTS: All patients (533) with CHD living in the study area were sent an invitation letter and a request for informed consent. Those who chose to participate answered a questionnaire about CHD risk factors and their current treatment, and their medical records were reviewed. The patients were divided into four groups on the basis of their history: I. Coronary artery bypass surgery (CABG), II. Percutaneous transluminal coronary angioplasty (PTCA), III. Myocardial infarction (MI), IV. Angina pectoris (AP). If a patient fulfilled the criteria for more than one diagnostic group the CABG group had the highest priority followed by PTCA, MI and finally AP. MAIN OUTCOME MEASURES: Blood pressure, smoking habits, BMI, exercise profile, cholesterol levels and drug therapy. RESULTS: Of 533 patients with CHD, 402 (75%) participated in the study, 15% were managed exclusively by their family physician and 23% by both cardiologists and family physicians. Obesity was relatively common, with nearly 60% being overweight (BMI > 25). Average cholesterol in the total group was 6.2 mmol/L (95% CI 6.07 to 6.34). Blood pressure had been recorded in 92% of the patients, and mean systolic and diastolic blood pressures were 143 and 82 mmHg, respectively. While 15% were current smokers, 56% were ex-smokers. A total of 113 patients (28%) were being treated with cholesterol-lowering drug therapy at the time of the study. Respective treatment ratios in the four subgroups were 47% in group I, 42% in II, 25% in III and 13% in group IV. Aspirin was taken by 284 patients (71%), beta blockers by 52% and calcium channel blockers by 36%. More than twice as many women than men were treated with nitrates, 57% versus 27%. CONCLUSIONS: The results indicate that there are numerous possibilities for improvements in secondary prevention and medical management of coronary heart disease in Iceland. Particular emphasis should be placed on smoking cessation, life-style modification with exercise and diet recommendations to lower BMI and lipid-lowering therapy.
