Background
Emergency room (ER) use is increasing in several countries. Variability in the proportion of non-urgent ER visits was found to range from 5 to 90 % (median 32 %). Non-urgent emergency visits are considered an inappropriate and inefficient use of the health-care system because they may lead to higher expenses, crowding, treatment delays, and loss of continuity of health care provided by a general practitioner. Urgency levels of doctor–walk-in patient encounters were assessed based on their region of origin in a diverse Norwegian population.
Methods
An anonymous, multilingual questionnaire was distributed to all walk-in patients at a general emergency outpatient clinic in Oslo during two weeks in September 2009. We analysed demographic data, patient–doctor assessments of the level of urgency, and the results of the consultation. We used descriptive statistics to obtain frequencies with 95 % confidence interval (CI) for assessed levels of urgency and outcomes. Concordance between the patients’ and doctors’ assessments was analysed using a Kendall tau-b test. We used binary logistic regression modelling to quantify associations of explanatory variables and outcomes according to urgency level assessments.
Results
The analysis included 1821 walk-in patients. Twenty-four per cent of the patients considered their emergency consultation to be non-urgent, while the doctors considered 64 % of encounters to be non-urgent. The concordance between the assessments by the patient and by their doctor was positive but low, with a Kendall tau-b coefficient of 0.202 (p < 0.001). Adjusted logistic regression analysis showed that patients from Eastern Europe (odds ratio (OR) = 3.04; 95 % CI 1.60–5.78), Asia and Turkey (OR = 4.08; 95 % CI 2.43–6.84), and Africa (OR = 8.47; 95 % CI 3.87–18.5) reported significantly higher urgency levels compared with Norwegians. The doctors reported no significant difference in assessment of urgency based on the patient’s region of origin, except for Africans (OR = 0.64; 95 % CI 0.43–0.96).
Conclusion
This study reveals discrepancies between assessments by walk-in patients and doctors of the urgency level of their encounters at a general emergency clinic. The patients’ self-assessed perception of the urgency level was related to their region of origin.

Background
The Oslo Accident and Emergency Outpatient Clinic (OAEOC) experienced a 5–6 % annual increase in patient visits between 2005 and 2011, which was significantly higher than the 2–3 % annual increase among registered Oslo residents. This study explored immigrant walk-in patients’ use of both the general emergency and trauma clinics of the OAEOC and their concomitant use of regular general practitioners (RGPs) in Oslo.
Methods
A cross-sectional survey of walk-in patients attending the OAEOC during 2 weeks in September 2009. We analysed demographic data, patients’ self-reported affiliation with the RGP scheme, self-reported number of OAEOC and RGP consultations during the preceding 12 months. The first approach used Poisson regression models to study visit frequency. The second approach compared the proportions of first- and second-generation immigrants and those from the four most frequently represented countries (Sweden, Pakistan, Somalia and Poland) among the patient population, with their respective proportions within the general Oslo population.
Results
The analysis included 3864 patients: 1821 attended the Department of Emergency General Practice (“general emergency clinic”); 2043 attended the Section for Orthopaedic Emergency (“trauma clinic”). Both first- and second-generation immigrants reported a significantly higher OAEOC visit frequency compared with Norwegians. Norwegians, representing 73 % of the city population accounted for 65 % of OAEOC visits. In contrast, first- and second-generation immigrants made up 27 % of the city population but accounted for 35 % of OAEOC visits. This proportional increase in use was primarily observed in the general emergency clinic (42 % of visits). Their proportional use of the trauma clinic (29 %) was similar to their proportion in the city. Among first-generation immigrants only 71 % were affiliated with the RGP system, in contrast to 96 % of Norwegians. Similar finding were obtained when immigrants were grouped by nationality. Compared to Norwegians, immigrants from Sweden, Pakistan and Somalia reported using the OAEOC significantly more often. Immigrants from Sweden, Poland and Somalia were over-represented at both clinics. The least frequent RGP affiliation was among immigrants from Sweden (32 %) and Poland (65 %).
Conclusions
In Norway, immigrant subgroups use emergency health care services in different ways. Understanding these patterns of health-seeking behaviour may be important when designing emergency health services.

Purpose
To analyze associations among the negative life experiences and health-care-seeking of adolescents during the 12 months before the study.
Methods
Cross-sectional questionnaire study among 10th-year students at all secondary schools in Oslo.
Results
In 2000 and in 2001, 7329 (88%) of Oslo�s 8316 secondary-school students responded to the questionnaire. Some contacts with primary health care during the previous year were reported by 71% of respondents, and 6% had seen a mental health practitioner (psychologist or psychiatrist). Health care utilization was not correlated with the family�s financial situation as reported by the student (boys = 1019; girls = 1258), or with a parent�s unemployment (boys = 253; girls = 325). The 2112 boys (59% of all) and 2378 girls (64%) who reported feeling strong pressure from others to succeed, had more contacts with all primary health care services. Girls, but not boys, who reported being bullied by others reported more psychologist or psychiatrist visits than did their nonbullied peers. Exposure to physical violence was associated with a significant increase in visits to the School Health Service, family physician, and emergency medical service, and was related to more than doubling the probability of visiting a mental health practitioner. Being sexually violated during the previous year increased the likelihood of boys visiting mental health practitioner more than four times (odds ratio [OR] 4.6; 95% confidence interval [CI] 1.7�12.2); and visiting School Health Service by nearly four times, (OR 3.7; 95% CI 1.0�13.5).
Conclusion
Variation in adolescent health care seeking can, by and large, be predicted by negative life experiences.

BACKGROUND: The role of large colony streptococci groups C or G as pathogen agents in sore throat has been questioned. AIM: To analyse clinical features of patients with large colony streptococci groups C or G compared with patients with group A streptococci (GAS) and with negative cultures. DESIGN OF STUDY: Prospective study of patients with sore throat. SETTING: Two Norwegian general practices in Stokke and Kongsberg communities with 6500 patients.METHOD: Frequency of clinical features in the three patient categories including the four Centor criteria (fever, anterior cervical lymphadenopathy, tonsillar exudates, and lack of cough), degree of pain on swallowing, pharyngeal rubor, C-reactive protein (CRP) values, patient age between 3 and 14 years, and duration of symptoms before seeing the doctor. A logistic regression analysis to find independent predictors was performed. RESULTS: Out of 306 patients with a sore throat, 244 were adults and 62 were children under 10 years old; 40% were men. One hundred and twenty-seven had GAS, 33 had streptococci groups C or G, and 146 had negative throat cultures. Forty-eight per cent of the GAS patients and 45% of the C or G patients met three or four of the Centor criteria. The logistic regression revealed that in patients with GAS considerable pain on swallowing, an age of 3-14 years and a duration of symptoms of < or =3 days or less were significantly associated with GAS infection in addition to the Centor criteria. The same results were found when all streptococci were analysed together, in addition elevated CRP was significant. In patients with streptococci group C or G an elevated CRP-value was significantly associated. CONCLUSION: Patients with tonsillitis caused by streptococcus groups C or G have, to a large extent, the same clinical picture as patients with GAS. Large colony streptococci groups C and G should be considered as throat pathogens in line with GAS.

Bakgrunn. Halsinfeksjon er vanlig i allmennpraksis, ofte karakterisert som «vondt i halsen» eller sår hals. Det kan være betydelig smerte og ubehag ved alle typer halsinfeksjon. Vi ønsket å finne ut om en av eller begge de to forskjellige råmelkstablettene på det norske markedet kan forkorte sykdomsforløpet ved halsinfeksjoner som ikke er forårsaket av gruppe A-streptokokker.
Materiale og metoder. Studien var prospektiv, dobbeltblind, randomisert og placebokontrollert. 148 voksne personer med sår hals ble rekruttert i fem norske militærleirer vintrene 1999 - 2001. Hovedutfallsmål var grad av halsonde og sykdomsfølelse, målt ved visuell analoge skalaer (VAS), og antall dager til pasienten følte seg frisk. Pasientene ble delt i tre grupper som fikk henholdsvis Vekk i morgen, Curamed eller placebo sugetabletter som de skulle ta inntil de følte seg friske.
Resultater. 148 pasienter fullførte studien. I alle de tre gruppene var det en smertereduksjon på ca. 50 % etter seks dager, men det var ingen signifikante forskjeller mellom gruppene. Curamed-gruppen hadde en noe lavere, ikke-signifikant utgangsverdi for sykdomsfølelse og en lavere reduksjon i symptomstyrke enn de to andre gruppene. Forskjellene i symptomreduksjon mellom gruppene var ikke signifikante. Det var heller ikke signifikante forskjeller mellom gruppene når det gjaldt antall dager til pasienten følte seg frisk.
Fortolkning. I vår studie ble det ikke funnet noen effekt av Vekk i morgen og Curamed på halsondet og sykdomsfølelsen hos personer med halsinfeksjon

Questionnaire survey, carried out as part of The Oslo Health Study in 2001-2002. Data from 821 persons (40 and 45 year old) living in a less affluent inner city area (called east) were compared with 854 persons living in an affluent area of the city (called west).
Musculo-skeletal pain is reported by 55-60 % of middle aged persons in Oslo during a four week period, and must be considered a normal phenomenon. Poor social conditions, inactivity, mental health problems and beeing an immigrant imply increased risk of more severe symptoms with a concomitant demand of health care.
