Bacterial findings in patients referred to hospital for the treatment of acute tonsillitis with or without peritonsillar phlegmon

BackgroundThe vast majority of patients with acute tonsillitis (AT) are managed in general practice. However, occasionally patients are referred to hospital for specialized management because of aggravated symptoms and/or findings suggestive of peritonsillar involvement. No prospective studies have been conducted aiming to investigate the prevalent and significant microorganisms in this highly selected group of patients. We aimed to describe the microbiological findings of acute tonsillitis with or without peritonsillar phlegmon (PP) in patients referred for hospital treatment and to point out potential pathogens using the following principles to suggest pathogenic significance: (1) higher prevalence in patients compared to healthy controls, (2) higher abundance in patients compared to controls, and (3) higher prevalence at time of infection compared to time of follow up.MethodsMeticulous and comprehensive cultures were performed on tonsillar swabs from 64 patients with AT with (n = 25) or without (n = 39) PP and 55 healthy controls, who were prospectively enrolled at two Danish Ear-Nose-Throat Departments between June 2016 and December 2019.ResultsStreptococcus pyogenes was significantly more prevalent in patients (27%) compared to controls (4%) (p < 0.001). Higher abundance was found in patients compared to controls for Fusobacterium necrophorum (mean 2.4 vs. 1.4, p = 0.017) and S. pyogenes (mean 3.1 vs. 2.0, p = 0.045) in semi-quantitative cultures. S. pyogenes, Streptococcus dysgalactiae, and Prevotella species were significantly more prevalent at time of infection compared to follow up (p = 0.016, p = 0.016, and p = 0.039, respectively). A number of species were detected significantly less frequently in patients compared to controls and the mean number of species was significantly lower in patients compared to controls (6.5 vs. 8.3, p < 0.001).ConclusionsDisregarding Prevotella spp. because of the prevalence in healthy controls (100%), our findings suggest that S. pyogenes, F. necrophorum, and S. dysgalactiae are significant pathogens in severe AT with or without PP. In addition, infections were associated with reduced diversity (dysbacteriosis).Trial registrationThe study is registered in the ClinicalTrials.gov protocol database (# 52,683). The study was approved by the Ethical Committee at Aarhus County (# 1-10-72-71-16) and by the Danish Data Protection Agency (# 1-16-02-65-16).

EP03.01-015 Disease-Free Survival and Clinical Characteristics in Early-Stage NSCLC Patients From a Danish Cohort

New and targeted treatment options in early-stage non-small cell lung cancer (NSCLC) patients have the potential to increase survival, but further characterization is needed to improve patient selection. Here, we present real-world patient characteristics, survival data, and disease-free survival (DFS) patterns of early-stage NSCLC patients treated in the county of Aarhus, Denmark.

Trends of endodontic and periapical status in adult Danishpopulations from 1997 to 2009: A repeated cross-sectional study.

To compare the endodontic and periapical status of two similar adult Danish populations examined in 1997-1998 and 2007-2009, respectively. Two populations from Aarhus County, Denmark (age range: 20-64years) were randomly selected using the Danish Civil Registration System. Full-mouth intraoral radiographs (14 periapical, 2 bitewing) of 616 individuals in 1997-1998 (C1: 16018 teeth) and 398 individuals in 2007-2009 (C2: 10668 teeth) were taken to ascertain the number of teeth, presence of root fillings (RFs) and apical periodontitis (AP) using the periapical index (PAI). T-tests with unequal variances were used to assess differences between C1 and C2 with respect to age and the number of teeth. Multivariable and multinomial logistic regression analyses were used to assess the effect of cohort, age and tooth type on the prevalence and relative frequency of RFs and AP. Mean age and mean number of teeth were higher in C2 than C1 (age; C1: 42.3years, C2: 44.6years; p=.003), (teeth; C1: 26.0, C2: 26.8; p<.001). The prevalence of root filled teeth was lower in C2 than C1 (C1: 51.8%, C2: 45.0%; p=.03); however, the prevalence of AP was similar (C1: 42.0%, C2: 45.0%). The relative frequency of root filled teeth was lower in C2 than C1 (C1: 4.8%, C2: 3.6%; p=.004), although the individuals were older in C2. The relative frequency of AP was similar in the two cohorts (C1: 3.3%, C2: 3.6%; p=.42). The relative frequency of AP in non-root filled teeth doubled from 0.9% in C1 to 1.8% in C2. C2had higher PAI scores than C1 for root filled and non-root filled teeth, despite age correction (p≤.0007). Two similar general Danish populations examined, respectively, in 1997-1998 and 2007-2009, were associated with a decreasing trend in the prevalence and relative frequency of RFs over the decade. There was no difference in relative frequency of AP in root filled teeth, but an increase in relative frequency of AP in non-root filled teeth. Further population-based studies including analysis of non-root filled teeth using the full-scale PAI and quality assessment of restorations are recommended.

P27.03 Increase in Overall Survival for Locally Advanced NSCLC Patients From 2010 to 2018 - A Registry Based Study in Denmark

Standard of care for NSCLC patients with unresectable disease has remained largely unchanged, either curatively intended chemoradiotherapy (CRT) followed by active surveillance, or palliative treatment. However, overall survival has improved recently, possibly due to more targeted patient selection and improved diagnostic imaging, new radiation modalities, and increased subsequent lines of treatment. Here, we describe treatment patterns and survival in the real world for stage III NSCLC patients diagnosed in the county of Aarhus, Denmark.

Risk factors for violence-related injuries in emergency departments: a Danish linkage study

ABSTRACT Background: Interpersonal violence is a pervasive global public health problem associated with myriad health, social and economic consequences. In recent years the rates of interpersonal violence have decreased, however, high numbers of individuals continue to present to emergency departments for non-fatal violence-related injuries. Objective: This study aimed to examine a range of risk factors associated with violence-related injuries in an emergency department in Denmark. Method: A case-control study was conducted on a sample of 3,940 victims of violence collected by the Accident Analysis Center for Aarhus County Municipality. Using the Danish Civil Registry System, controls were matched 10:1 on age, gender and municipality. Risk factors were rendered from Danish health and social registers five years prior to the violent assault. These included marital status, educational qualification, employment status, national origin, involvement with child protective services (CPS), prior convictions, and a diagnosis of adjustment disorder and alcohol and/or substance use disorders. Results: Multivariate logistic regression identified that being male, divorced, unmarried, non-Danish origin, attending compulsory education, being outside the labour force, students, involvement with CPS, prior criminal conviction and a diagnosis of alcohol and/or substance use disorders were associated with an increased likelihood of being exposed to violence. The dominant risk factors were alcohol and/or substance use disorders (OR = 3.62) and prior criminal conviction (OR = 3.54). Attainment of tertiary education was associated with a reduced likelihood of being a victim of violence. Conclusion: These findings highlight that research into effective interventions offered in emergency departments may help the public health effort to reduce the health, social and economic burden of interpersonal violence.

Prescription and predictors of post-stroke antidepressant treatment: A population-based study.

Post-stroke depression and pathological crying are common and potentially serious complications after stroke and should be diagnosed and treated accordingly. Diagnosis and treatment probably rely on clinical experience and may pose certain challenges. We aimed to examine prescription and predictors of antidepressant treatment after ischemic stroke in a clinical setting. In this registry-based follow-up study, consecutive ischemic stroke patients were identified from the Danish Stroke Registry, holding information on antidepressant treatment during admission in Aarhus County from 2003 to 2010. Information on prescription after discharge was obtained from the Danish Prescription Database. Treatment initiation was analyzed using the cumulative incidence method including death as a competing risk. Multiple logistic regression was used to identify potential predictors of treatment. Among 5070 consecutive first-ever ischemic stroke patients without prior antidepressant treatment, the cumulative incidence of antidepressant treatment and prescription over 6months was 35.2% (95% CI: 33.8-36.6). Overall 16.5% (95% CI: 15.5-17.6) started treatment within 14days corresponding to 48.1% (95% CI: 45.8-50.5) of all treated patients, and the most widely prescribed group of antidepressants was selective serotonin reuptake inhibitors (86%). Increasing stroke severity was associated with higher odds of initiating treatment. Antidepressant treatment in this real-life clinical setting was common and initiated early, in almost half the treated patients within 14days. Our results suggest that special focus should be given to the severe strokes as they may have a greater risk of requiring treatment.

Trajectories of suicidal ideation in patients with first-episode psychosis: secondary analysis of data from the OPUS trial

Heterogeneity in suicidal ideation over time in patients with first-episode psychosis is expected, but prototypical trajectories of this have not yet been established. We aimed to identify trajectories of suicidal ideation over a 3-year period and to examine how these trajectories relate to subsequent suicidality. We used longitudinal data from the prospective 10-year follow-up OPUS trial of young Danish patients with first-episode psychosis. Participants were recruited between January, 1998, and December, 2000, from all inpatient and outpatient mental health services in Copenhagen and Aarhus County, were aged between 18 and 45 years, and had a diagnosis in the schizophrenia spectrum. Randomisation was done by a computer-generated randomisation list, stratified in alternating blocks for five centres. In Aarhus, a secretary drew lots when the researcher phoned her. Patients were randomly assigned to a treatment group (modified assertive community treatment) or a control group (standard treatment at community mental health centres) and assessed at treatment initiation, and after 1, 2, 5, and 10 years. We included all patients' data on suicidal ideation from the first three assessments in a latent growth mixture modelling analysis to empirically identify trajectories of suicidal ideation. Multivariable logistic regression analyses were applied to estimate associations between trajectories and subsequent suicidality. This trial is registered with ClinicalTrials.gov, number NCT00157313. Three trajectories for suicidal ideation were identified in 521 patients. 317 of 521 members (61%) of the largest trajectory, low-decreasing, consisted of patients who initially reported suicidal ideation once-to-a-few-times in the past year followed by a decrease in suicidal ideation. 172 of 521 (33%) members of the frequent-stable trajectory reported suicidal ideation sometimes-to-frequently at the first assessment and remained stable over time. Finally, 32 of 521 (6%) members of the frequent-increasing trajectory reported frequent suicidal ideation initially followed by worsening. Compared with the low-decreasing class, the risk of persistent suicidal ideation was higher for patients in the frequent-stable and frequent-increasing classes at 5 years (Odds ratio=4·5, 95% CI 2·50-8·02 and 4·7, 1·55-14·24 respectively) and at 10 years (4·2, 2·42-7·13 and 3·2, 1·20-8·70 respectively). Also the risk of suicide attempt at 5 years was higher for patients in the frequent-stable (2·8, 1·07-7·43) and frequent-increasing classes (6·6, 1·69-25·54) compared with the low-decreasing class. There was no difference in suicide rate at 5 or 10 years between trajectories. Because up to 40% of patients experienced frequent suicidal ideations that persisted or increased during the first years of treatment, our findings warrant special focus on suicidal issues as an integral part of treatment along with treatment to target psychotic symptoms.

Prediction of periapical status and tooth extraction.

To describe and analyse risk factors associated with prediction of periapical status, assessed using the full-scale Periapical Index (PAI) supplemented with extraction as outcome variable. In 1997-1998, 616 randomly selected individuals from Aarhus County, Denmark, underwent a full-mouth radiographic survey. All 616 were re-invited in 2003-2004 and in 2008-2009, when 473 and 363 persons, respectively, consented and attended a new radiographic examination. The study population of the present investigation included 330 persons who had participated in all three examinations, and 143 persons who had participated in the first and second examination only. Using the full-mouth radiographic survey and interview information, the following variables were assessed: on person level - age, gender, smoking habits and number of teeth; on tooth level - presence of tooth, PAI, root filling, caries, marginal bone level, restoration, jaw and tooth group. The outcome variable was the 5 score PAI supplemented with extraction. The observation period was 5years. Ordered logistic regression analyses were carried out for root filled and non-root filled teeth separately. The Regional Committee of Ethics approved the study. For both root filled teeth and non-root filled teeth, the baseline PAI score was the most important predictive factor of periapical status and extraction (P<0.0001). Non-root filled teeth had in general a better outcome than root filled teeth. However, in non-root filled teeth, several other factors had a significant influence on the outcome, and the risk estimates were larger and showed a more pronounced variation between the different categories of predictive factors. For root filled teeth few variables, other than baseline PAI score, influenced the outcome significantly. The full-scale PAI was the strongest predictive factor of periapical status or extraction even when adjusted for additional factors, such as marginal bone level. A high baseline PAI score increased the risk for an impaired outcome. The large difference in risk estimates for non-root filled compared to root filled teeth documents the importance of separate analyses/studies for identification and quantification of predictive factors associated with periapical status and extraction of a tooth.

Symptoms and findings in adult-onset celiac disease in a historical Danish patient cohort

Objective: The presentation of celiac disease (CD) has changed over the past decades. We aimed to describe the incidence of CD and its complications at diagnosis in a historical cohort in a well-defined population in Denmark. Methods: We included all patients aged 15+ years, who lived in Aarhus County, Denmark, and who were diagnosed with CD between January 2008 and August 2013. Data regarding gastrointestinal symptoms, anthropometrics, biochemistry, and bone mineral density were retrieved from patient records. Results: A total of 93 patients with a valid CD diagnosis were identified, corresponding to an incidence rate of 6.4 per 100,000 person-years. At diagnosis, diarrhea and weight loss occurred in 54% and 47% patients, respectively. In total, 30% had anemia; 40%, iron deficiency; 20%, folate deficiency; and 17%, vitamin B12 deficiency. Vitamin D deficiency was present in 34%. In 28%, bone mineral density was determined during the first year after diagnosis. Of these, 54% had osteopenia and 12% osteoporosis. After introduction of a gluten-free diet, 28% had normalized transglutaminase antibody levels after 6 months, and 56% did after 12 months. Diabetes mellitus type 1 was present in 7%; dermatitis herpetiformis, in 3%; and thyroid dysfunction, in 5%. Conclusions: Only half of newly diagnosed CD patients presented with classic gastrointestinal symptoms. Anemia and vitamin deficiencies were common. Bone mineral density was determined in less than a third of the patients, and osteoporosis occurred in 12% of these. Serologic markers of CD normalized in approximately half of patients during the first year after the diagnosis.

General practitioners' anticipated risk of cancer at referral and their attitude to risk taking and to their role as gatekeeper.

General practitioners have to deal with situations characterized by real but low likelihoods of serious illness. We aimed to investigate variations in general practitioners' anticipated risk of cancer when referring a patient and associations both with general practitioners' attitudes to risk taking and with their gatekeeper role. In January 2012, all 835 active general practitioners in the county of Aarhus, Denmark, received a questionnaire including the Physician Reaction to Uncertainty scale, The Tolerance for Ambiguity scale, the Physician Risk Attitude scale and a number of single items assessing anticipated risk of cancer when referring a hypothetical 50-year-old patient, use of intuition and perception of their role as a gatekeeper. A total of 568 (68.0%) practitioners completed and returned the questionnaire. The median anticipated risk of cancer was 30% (inter-quartile range: 15%-50%) and the 5%-95% centiles were 5% and 80%. Increasing tolerance for ambiguity was strongly related to a declining anticipated risk of cancer. None of the other risk attitudes were associated with the anticipated risk of cancer at referral. Increased general practitioners' age was related to increased anticipated risk of cancer when referring (25% for general practitioners under 45 years to 43% for those 60 years or over) but not statistically important. General practitioners either overestimate the risk of cancer when referring for suspected cancer or they appear to need to be very sure of the cancer diagnosis before referral. Further, focus on tolerance for ambiguity should be included in the education of general practitioners.

Are Cancer Patients' Socioeconomic and Cultural Factors Associated with Contact to General Practitioners in the Last Phase of Life?

Introduction. General practitioners (GPs) play an important role in end of life care, which should be offered regardless of socioeconomic position and cultural factors. The aim was to analyse associations between GP contacts at the end of life and socioeconomic and cultural characteristics of Danish cancer patients. Method. Population-based study identifying 599 adults who died of cancer from March to November 2006, in Aarhus County, Denmark. Associations between health register-based data on “total GP face-to-face contacts” and “GP home visits” during the last 90 days of life and patients' socioeconomic and cultural characteristics were calculated. Results. Having low income (RR: 1.18 (95% CI: 1.03; 1.35)) and being immigrants or descendants of immigrants (RR: 1.17 (95% CI: 1.02; 1.35)) were associated with GP face-to-face contacts. However, patients living in large municipalities had lower likelihood of having both GP face-to-face contacts in general (RR: 0.85 (95% CI: 0.77;0.95)) and GP home visits (RR: 0.89 (95% CI: 0.80; 0.99)). Conclusion. This study indicates higher proportion of GP contacts to economically deprived patients and immigrants/descendants of immigrants. These subgroups were, however, small and results should be looked upon with caution. Furthermore, palliative needs were not included and together with urban/rural the underlying causes need further investigation.

Early Antidepressant Treatment and All-Cause 30-Day Mortality in Patients with Ischemic Stroke

Background: Antidepressants, in particular selective serotonin reuptake inhibitors, have been associated with antithrombotic and neuroprotective properties and their more widespread use has been suggested in stroke recovery. However, data are sparse on their effects on the clinical outcome, including mortality, associated with early antidepressant treatment after stroke. We aimed to study all-cause 30-day mortality related to early antidepressant treatment in patients with ischemic stroke. Methods: We did a population-based follow-up study identifying patients from the Danish Stroke Registry admitted in the former Aarhus County from 2003 to 2010. During this time, initiation of antidepressant treatment during admission was registered in the Danish Stoke Registry. The registry also holds clinical information including stroke type, stroke severity and quality of in-hospital stroke care. Information on vital status and covariates including comorbidities and co-medication was obtained from the following population-based medical registries: the Danish Civil Registration System, Danish Medicines Agency's Medical Register and The Danish National Patients Registry. Information was linked using the unique civil registration number assigned to all Danish residents. Multivariable logistic regression was used to compute the adjusted odds ratio (OR) of 30-day mortality in patients treated with antidepressants during admission as compared to patients not treated. In addition, we did stratified analyses on sex, age, stroke severity and propensity score-matched analyses as well as multiple imputation. Results: Among 5,070 consecutive first-ever stroke patients without prior antidepressant treatment, 955 (18.8%) started antidepressant treatment during admission with a median time from admission until treatment of 5 days (interquartile range 2-11). The proportion of patients with severe stroke was higher among treated patients as compared to that among non-treated patients. The adjusted OR of 30-day mortality was 0.28 (95% confidence interval (CI) 0.18-0.43) for patients treated during admission as compared to patients not treated during admission. Stratification by stroke severity showed signs of effect modification, stratification by sex and age did not. Included in the propensity score-matched analyses were 1,908 patients matched 1:1. The propensity score-matched adjusted OR of death within 30 days was 0.31 (95% CI 0.19-0.49). Conclusion: Although early antidepressant treatment was more often started in patients with severe stroke, treatment was associated with significantly lower mortality. This result requires replication in randomized trials; however, it indicates that early start of antidepressant treatment after stroke may be safe and a more routine use may be feasible.

Incidence and microbiology of peritonsillar abscess: the influence of season, age, and gender

To explore the correlations among the incidence, microbiology, season, gender, and age in patients with peritonsillar abscess (PTA) in order to identify risk factors for PTA development. All patients with PTA treated at private ENT practices in Aarhus County and in the Ear-Nose-Throat Departments at Aarhus University Hospital and Randers Hospital from January 2001 to December 2006 were included in the study. Age- and gender-stratified population data for Aarhus County for the same 6 years were obtained. The incidence rate of PTA increased from childhood to peak in teenage life and declined afterward gradually until old age. Girls predominated over boys until the age of 14 years. Subsequently, men were more frequently affected than women. Fusobacterium necrophorum (FN) was significantly more prevalent than group A Streptococcus (GAS) among patients aged 15-24 years (P < 0.001). In contrast, GAS was significantly more frequently recovered among children aged 0-9 years and adults aged 30-39 years compared with FN (P < 0.001 and P = 0.017 respectively). The seasonal variation of PTA was statistically insignificant (P = 0.437). However, GAS was significantly more frequently recovered in the winter and spring than in the summer (P = 0.002 and P = 0.036 respectively). There was a trend toward a higher incidence of FN infection during the summer than the winter (P = 0.165). Although the collected PTA incidence was stable throughout the year, the microbiology fluctuated with seasons. Patients aged 15-24 years are at an increased risk of PTA due to FN, which may have clinical implications for the diagnostic work-up and treatment of patients with acute tonsillitis.

Risk of Burnout in Danish GPs and Exploration of Factors Associated with Development of Burnout: A Two-Wave Panel Study

Background. We assessed risk of burnout in GPs during a 7-year followup and examined whether (1) thoughts about changing medical specialty increased the risk of burnout and (2) burned out GPs had higher job turnover rates than burnout-free GPs. Methods. In 2004 and 2012, all GPs in the county of Aarhus, Denmark, were invited to participate in a survey. Retirement status of physicians who participated in 2004 was obtained through the Registry of Health Providers in 2012. Results. 216 GPs completed both surveys. The risk of developing burnout during the 7-year followup was 13.2% (8.2–19.6%). GPs who in 2004 were burnout-free and reported that they would not select general practice as medical specialty again had a statistically significant increased risk of burnout in 2012 (OR = 4.5; 95% CI = 1.2–16.5; P = 0.023). Among GPs with burnout in 2004, 25.0% had withdrawn from general practice during followup compared to 28.8% of burnout-free GPs in 2004 (adj. OR = 0.99; 95% CI = 0.48–2.02; P = 0.975). Conclusion. The 7-year incidence of burnout was 13%. Thoughts about changing medical specialty were an important predictor of burnout. Burned out GPs had not higher job turnover rates than burnout-free GPs.

Agreement between patient-reported and doctor-reported patient intervals and date of first symptom presentation in cancer diagnosis – A population-based questionnaire study

Background: The concept of delay in cancer diagnosis has been a scientific issue for decades, and there is still no standardised and validated way to measure the time intervals. One of the intervals that are difficult to measure is the patient interval (i.e. the period from the patient's first symptom until the first presentation to the health care system) because dates of symptom onset and first presentation are difficult to establish precisely. Further, since patients may have another experience of the diagnostic pathway than e.g. the general practitioner (GP), a reasonable question remains whether patients and GPs agree on these important milestones. The objective of this study was to analyse the agreement between patient-reported and GP-reported patient intervals and date of first presentation of cancer-related symptom(s) to the GP. Methods: On the basis of a cohort study, we included incident cancer patients from the former Aarhus County from 1 September, 2004 to 31 August, 2005. Both patients and GPs reported the length of the patient interval and the date of the first presentation to the GP with a cancer-related symptom measured by self-administered questionnaires. Agreement was measured using agreement-survival plots and Lin's concordance correlation coefficient (CCC). Results: There was full agreement between GP- and patient-reported patient intervals in 21.0% of all the cancer cases. In 50.1% of cases, patients and GPs agreed about the patient interval within a margin of one month. There was full agreement between GP- and patient-reported date of first presentation in 37.5% of the cancer cases and within one week in 52.0% of all the cancer cases. Overall, the agreement on the length of the patient interval was poor (CCC=0.513), but better for patients presenting with alarm symptoms. The agreement was moderate between GP- and patient-reported dates of first presentation (CCC=0.924). Conclusion: We found that GPs systematically reported a longer patient interval than patients did. We found moderate agreement on reported date of first presentation of symptoms to the GP, meaning that the disagreement in reported patient interval is related to date of first symptom rather than date of first presentation to the GP.

Patient Delay in Colorectal Cancer Patients: Associations with Rectal Bleeding and Thoughts about Cancer

Rectal bleeding is considered to be an alarm symptom of colorectal cancer. However, the symptom is seldom reported to the general practitioner and it is often assumed that patients assign the rectal bleeding to benign conditions. The aims of this questionnaire study were to examine whether rectal bleeding was associated with longer patient delays in colorectal cancer patients and whether rectal bleeding was associated with cancer worries. All incident colorectal cancer patients during a 1-year period in the County of Aarhus, Denmark, received a questionnaire. 136 colorectal cancer patients returned the questionnaire (response rate: 42%). Patient delay was assessed as the interval from first symptom to help-seeking and was reported by the patient. Patients with rectal bleeding (N = 81) reported longer patient intervals than patients without rectal bleeding when adjusting for confounders including other symptoms such as pain and changes in bowel habits (HR = 0.43; p = 0.004). Thoughts about cancer were not associated with the patient interval (HR = 1.05; p = 0.887), but more patients with rectal bleeding reported to have been wondering if their symptom(s) could be due to cancer than patients without rectal bleeding (chi2 = 15.29; p<0.001). Conclusively, rectal bleeding was associated with long patient delays in colorectal cancer patients although more patients with rectal bleeding reported to have been wondering if their symptom(s) could be due to cancer than patients without rectal bleeding. This suggests that assignment of symptoms to benign conditions is not the only explanation of long patient delays in this patient group and that barriers for timely help-seeking should be examined.

Access to Outreach Specialist Palliative Care Teams among Cancer Patients in Denmark

Equal access to end-of-life care is important. However, social inequality has been found in relation to place-of-death. The question is whether social and economic factors play a role in access to specialist palliative care services. The study analyzed the association between access to outreach specialist palliative care teams (SPCTs) and socioeconomic characteristics of Danish cancer patients who died of their cancer. The study was a population-based, cross-sectional register study. We identified 599 adults who had died of cancer from March 1 to November 30, 2006, in Aarhus County, Denmark. Data from health registers were retrieved and linked based on the unique personal identifier number. Multivariate analysis with adjustment for age, gender, and general practitioner (GP) involvement showed a higher probability of contact with an SPCT among immigrants and descendants of immigrants than among people of Danish origin (prevalence ratio [PR]: 1.55; 95% confidence interval (CI): 1.04;2.31) and among married compared to unmarried patients (PR: 1.25; 95% CI: 1.01;1.54). The trends were most marked among women. We found an association between females, married patients, and female immigrants and their descendants and access to an SPCT in Denmark. However, no association with the examined economic factor was found. Need for specialized health care, which is supposed to be the main reason for access to an SPCT, may be related to economic imbalance; and despite the relative equality found, SPCT access may not be equal for all Danish residents. Further research into social and economic consequences in palliative care services is warranted.

Smoking promotes peritonsillar abscess

Peritonsillar abscess (PTA) is a frequent complication to acute tonsillitis, in particular in adolescents and young adults. Smoking is most commonly initiated during adolescence and young adulthood. The study examines whether smoking increases the risk of PTA and whether smoking is associated with the bacterial findings in PTA. All patients with PTA admitted to the Ear-Nose-Throat Department at Aarhus University Hospital from January 2001 through December 2006 were included in the study. Age- and gender-stratified data on smoking habits in the Danish population and demographic data for Aarhus County for the same 6 years were obtained. Smoking status was available for 679 (80 %) of 847 patients with PTA. 247 (36 %) patients admitted to daily tobacco smoking. Age-stratified odds ratios of smokers compared to non-smokers, for developing PTA, were in the range of 1.9-4.7. Fusobacterium necrophorum and beta-hemolytic streptococci were equally distributed between smokers and non-smokers. Twenty nine percent of the higher incidence of PTA among males compared to females could be explained by a higher prevalence of smoking in males. After correcting for differences in smoking prevalence by gender, the risk of PTA was calculated to be 9.5 % higher among males than females. Smoking was associated with significantly increased risk of PTA in both males and females of all ages. No differences in the microbiological flora of smokers and non-smokers with PTA were found.

Open Access to General Practice Was Associated with Burnout among General Practitioners

Walk-in open access in general practice may influence the general practitioner's (GP's) work, but very little research has been done on the consequences. In this study from Danish general practice, we compare the prevalence of burnout between GPs with a walk-in open access and those without. In a questionnaire study (2004), we approached all 458 active GPs in the county of Aarhus, Denmark, and 376 (82.8%) GPs returned the questionnaire. Walk-in open access was defined as at least 30 minutes every weekday where patients could attend practice without an appointment. Burnout was measured by the Maslach Burnout Inventory. Analyses using logistic regression were adjusted for gender, age, marital status, job satisfaction, minutes per consultation, practice organisation, working hours, number of listed patients per GP, number of contacts per GP, continuing medical education- (CME-) activities, and clusters of GPs. In all, 8% of GPs had open access and the prevalence of burnout was 24%. GPs with walk-in open access were more likely to suffer from burnout. Having open access was associated with a 3-fold increased likelihood of burnout (OR = 3.1 (95% CI: 1.1–8.8, P = 0.035)). Although the design cannot establish causality, it is recommended to closely monitor possible negative consequences of open access in general practice.
