Risk of selected postpartum infections after cesarean section compared with vaginal birth: A five‐year cohort study of 32,468 women

To compare the risk of postpartum infections within 30 days after vaginal birth, emergency, or elective cesarean section (CS). Register-based cohort study in Denmark. A total of 32,468 women giving birth in hospitals in the County of Aarhus, Denmark, during the period 2001-2005. Data from various hospital registries were combined and infections were identified by positive cultures, prescriptions for antibiotics and, re-operative procedures.Risk of postpartum infection was estimated and adjustment for potentially confounders was performed. Within 30 days postpartum, 7.6% of women who had underwent CS and 1.6% of women having a vaginal birth acquired an infection, yielding an adjusted odds ratio (OR) of 4.71, 95% confidence interval (CI): 4.08-5.43. The prevalence of postpartum urinary tract infection (UTI) was 2.8%, after CS and 1.5% after vaginal birth corresponding to an adjusted OR = 1.68, 95% CI: 1.38-2.03. The risk of UTI did not differ between emergency and elective CS. The prevalence of WI was 5.0% after CS and 0.08% after vaginal birth. Moreover, we found a nearly 50% higher risk of postpartum WI after emergency CS compared to elective CS (OR = 1.49, 95% CI: 1.13-1.97). More than 75% (697/907) of postpartum infections appeared after hospital discharge. The risk of postpartum infection seems to be nearly five-fold increased after CS compared with vaginal birth. This may be of concern since the prevalence of CS is increasing.

Socioeconomic factors related to attendance at a Type 2 diabetes screening programme

The prevalence of diabetes is increasing, and screening of high-risk populations is recommended. A low attendance rate has been observed in many Type 2 diabetes screening programmes, so that an analysis of factors related to attendance is therefore relevant. This paper analyses the association between socioeconomic factors and attendance for Type 2 diabetes screening. Persons aged 40-69 years (n = 4603) were invited to participate in a stepwise diabetes screening programme performed in general practitioners' offices in the county of Aarhus, Denmark in 2001. The study was population-based and cross-sectional with follow-up. The association between screening attendance in the high-risk population and socioeconomic factors was analysed by odds ratio. Forty-four percent of the estimated high-risk population attended the screening programme. In those with known risk for Type 2 diabetes, attenders were more likely to be older, to be unemployed and to live in the countryside than non-attenders. The risk for Type 2 diabetes was unknown for 21% of the study population; this group was younger and less likely to be cohabitant, skilled, or employed and to have middle or high income than the study population with known risk score for diabetes. A low attendance rate was found in this screening programme for Type 2 diabetes. No substantial socioeconomic difference was found between attenders and non-attenders in the high-risk population. Further research is needed to uncover barriers to screening of Type 2 diabetes in socioeconomically deprived persons.

Atrial fibrillation in patients with ischemic stroke: A population-based study

Atrial fibrillation is a major risk factor for ischemic stroke. However, the prognostic impact of atrial fibrillation among patients with stroke is not fully clarified. We compared patient characteristics, including severity of stroke and comorbidity, quality of in-hospital care and outcomes in a cohort of first-time ischemic stroke patients with and without atrial fibrillation. Based on linkage of public medical databases, we did a population-based follow-up study among 3,849 stroke patients from the County of Aarhus, Denmark admitted in the period of 2003-2007 and prospectively registered in the Danish National Indicator Project. Atrial fibrillation was associated with an adverse prognostic profile but not with an overall poorer quality of in-hospital care. Patients with atrial fibrillation had a longer total length of stay (median: 15 vs 9 days), and were at increased risk of in-hospital medical complications (adjusted relative risk = 1.48, 95% CI: 1.23-1.79) and recurrent stroke (adjusted hazard ratio = 1.30, 95% CI: 0.93-1.82) when compared with patients without atrial fibrillation. The adjusted hazard ratios for 30 days and one year mortality were 1.55 (95% CI: 1.20-2.01) and 1.55 (95% CI: 1.30-1.85), respectively. Patients not eligible to oral anticoagulant treatment had an increased risk of recurrent stroke (adjusted hazard ratio = 1.92, 95% CI: 1.19-3.11). Atrial fibrillation is associated with a poor outcome among patients with ischemic stroke particularly among patients, who are not eligible to oral anticoagulant treatment.

Quality of Care and Length of Hospital Stay Among Patients With Stroke

The relationship between quality of care and economic outcome measures, including length of stay (LOS), among patients with stroke remains to be clarified. To determine whether quality of care is associated with LOS among patients with stroke. In this population-based follow-up study, we included 2636 patients with stroke who had been admitted to dedicated stroke units in Aarhus County, Denmark, from 2003 to 2005. Quality of care was measured as fulfillment of 12 criteria: early admission to a stroke unit, early antiplatelet therapy, early anticoagulant therapy, early computed tomography/magnetic resonance imaging scan, early water swallowing test, early mobilization, early intermittent catheterization, early deep venous thromboembolism prophylaxis, early assessment by a physiotherapist and an occupational therapist, and early assessment of nutritional and constipation risk. Data were analyzed by linear regression clustered at the stroke units by multilevel modeling. Median LOS was 13 days (25th and 75th percentiles: 7, 33). Meeting each quality of care criteria was associated with shorter LOS. Adjusted relative LOS ranged from 0.67 (95% confidence interval (CI): 0.61-0.73) to 0.87 (95% CI: 0.81-0.93). The association between meeting more quality of care criteria and LOS followed a dose-response effect, that is, patients who fulfilled between 75% and 100% of the quality of care criteria were hospitalized about one-half as long as patients who fulfilled between 0% and 24% of the criteria (adjusted relative LOS: 0.53, 95% CI: 0.48-0.59). Higher quality of care during the early phase of stroke was associated with shorter LOS among patients with stroke.

Sickness absence and workplace levels of satisfaction with psychosocial work conditions at public service workplaces

The objective of this study was to examine the impact of psychosocial work conditions on sickness absence while addressing methodological weaknesses in earlier studies. The participants were 13,437 employees from 698 public service workplace units in Aarhus County, Denmark. Satisfaction with psychosocial work conditions was rated on a scale from 0 (low) to 10 (high). Individual ratings were aggregated to workplace scores. Analysis of variance was used to compare the average number of days of yearly sickness absence in three groups with different levels of satisfaction with psychosocial work conditions. Sickness absence was 30.8% lower in the most satisfied group (11.7 days/year (CI 95%: 10.2; 13.1)) than in the least satisfied group (16.9 days/year (CI 95%: 15.3; 18.6)) adjusted for the covariates included. Satisfaction with psychosocial work conditions has a strong and independent impact on sickness absence. Am. J. Ind. Med. 52:153-161, 2009. (c) 2008 Wiley-Liss, Inc.

Learning based on patient case reviews: an interview study

BackgroundRecent theories on adult learning recommend that learning is situated in real-life contexts. Learning is considered a continuous process in which every new experience builds on, and integrates with, previously accumulated experiences. Reviewing and reflecting on patient cases is in line with this learning approach. There has, however, been remarkably little research into how patient cases might be applied in professional education. The purpose of this article is to present family physicians' perceptions of the learning process initiated by reviewing patient cases.MethodsThirteen family physicians, who had all participated in a large project on cancer diagnosis in family practice (the CAP-project), currently carried out at the Research Unit for General Practice, University of Aarhus were interviewed on their experiences of reviewing patient cases. In the CAP-project family physicians (n = 467, 81%) in the County of Aarhus (640 000 inhabitants) completed 2,212 (83%) detailed questionnaires on all newly diagnosed patients with cancer encountered in their practices during a one year period (2004–2005). In order to complete the questionnaire the family physicians were required to perform a systematic case review of each patient: they had to consult their records to provide dates of symptom-presentation, investigations and treatments initiated, and reflect on previous encounters with the patients to give detailed information on his/hers knowledge of the patients' care seeking behaviour, mental health and risk factors.The purpose of this article is to present indebt interview-data on family physicians' perceptions of the learning process initiated by reviewing patient cases, and their evaluations of using patient case reviews as a learning method in family practice.ResultsThe process of reflection initiated by reviewing patient cases enabled family physicians to reconsider their clinical work procedures which potentially supported the transition from individual competence to personal capability. According to the physicians, they were not only able to identify needed changes, some reported that they were able to transform these ideas into action and do things more effectively. According to our data this transition takes place, because the learning processes initiated were based on real life experiences which equally initiated reflections on what to improve, as well as how to improve their work.ConclusionPatient case reviews initiate reflective processes providing feedback about performance in real life situations. Family physicians are in favour of patient case reviews as a learning method, because it embraces the complexities they encounter in their daily practice and is based on personal experiences.

Global measure of satisfaction with psychosocial work conditions versus measures of specific aspects of psychosocial work conditions in explaining sickness absence

BackgroundAttempts to identify particular aspects of psychosocial work conditions as predictors of sickness absence remain inconclusive. A global measure has previously been suggested to be an efficient way to measure psychosocial work conditions in questionnaires. This paper investigates whether satisfaction with specific aspects of psychosocial work conditions explains sickness absence beyond its association with a global measure of psychosocial work conditions.MethodsThe participants were 13,437 employees from 698 public service workplaces in Aarhus County, Denmark. 33 items from a questionnaire fell in groupings around six aspects of psychosocial work conditions: skill discretion, professionalism, management, decision authority, workload and cooperation. A global measure rating satisfaction with psychosocial work conditions on a scale from 0 to 10 was also included in the questionnaire. Individual ratings were aggregated to workplace scores. Analysis of variance and multiple linear regression was used to compare the average number of days of yearly sickness absence with different levels of satisfaction with six aspects of psychosocial work conditions. The covariates included were gender, age, occupation, size of workplace, contact to hospital, civil status and children below 13 living at home.ResultsDissatisfaction with each of the six aspects of psychosocial work conditions was associated with an increase in sickness absence. When all aspects were simultaneously included in the model, only skill discretion and professionalism were negatively associated with sickness absence. When a global measure of satisfaction with psychosocial work conditions was also included in the model none of the specific aspects showed a statistically significant association with sickness absence.ConclusionLow global satisfaction with psychosocial work conditions is associated with increased levels of sickness absence. Including specific aspects of psychosocial work conditions in the model does not provide further information regarding the nature of this association.

Screening history of women with cervical cancer: a 6-year study in Aarhus, Denmark

To identify possible weaknesses in cervical screening in Aarhus County, 10 years after the programme was introduced, screening histories were examined. A major problem for the screening programme was that 31% of women were never screened and 61% under-screened, the latter group being significantly dominated by older women and high-stage tumours.

Socioeconomic patient characteristics predict delay in cancer diagnosis: a Danish cohort study

BackgroundDelay in cancer diagnosis may be important for cancer prognosis. Large individual variations in the duration of delay have been observed. This study examines whether patients' socioeconomic characteristics are predictors of long patient-, doctor- and system-related delay in cancer diagnosis.MethodsDanish population-based cohort study. From September 2004 to September 2005, newly diagnosed cancer patients were enrolled from administrative registries. A total of 467 general practitioners in the County of Aarhus, Denmark, completed questionnaires on 2,212 cancer patients' diagnostic pathways. A total of 1,252 cancer patients filled in questionnaires on their socioeconomic characteristics (e.g. marital status, education, occupation, household income and fortune). Delay was categorised as short or long based on quartiles. Predictors of long delay were assessed in a logistic regression model using odds ratios (ORs) as a proxy of relative risks.ResultsIn regard to patient delay, retired female patients experienced shorter delays (OR 0.35, 95% confidence interval (95%CI) 0.13 to 0.98) than employed female patients, while female smokers experienced longer delays (OR 2.42, 95%CI 1.21 to 4.85) than female non-smokers.In regard to doctor delay, female patients with a large household fortune experienced shorter delays (OR 0.07, 95%CI 0.01 to 0.45) than economically less privileged female patients. Well-educated men experienced shorter delays (OR 0.40, 95%CI 0.16 to 1.00) than men with short education. Male patients experienced longer doctor delays (OR 2.11, 95%CI 1.11 to 4.02) than women when gender-specific cancers were excluded.In regard to system delay, female patients with a large household fortune experienced shorter delays (OR 0.46, 95%CI 0.21 to 0.99) than economically less privileged women, while female patients with a high alcohol intake experienced longer delays (OR 2.82, 95%CI 1.18 to 6.72) than women with an average intake.ConclusionWe found socioeconomic predictors of delay that allow us to hypothesize social inequalities in the distribution of delay, but, in general, only a few socioeconomic variables predicted delay in cancer diagnosis. Future research should examine a broader array of patients' personal characteristics.

Palliative care for cancer patients in a primary health care setting: Bereaved relatives' experience, a qualitative group interview study

BackgroundKnowledge about the quality and organisation of care to terminally ill cancer patients with a relatives' view in a primary health care setting is limited.The aim of the study is to analyse experiences and preferences of bereaved relatives to terminally ill cancer patients in a primary care setting to explore barriers and facilitators for delivery of good palliative home care.MethodsThree focus group interviews with fourteen bereaved relatives in Aarhus County, Denmark.ResultsThree main categories of experience were identified: 1) The health professionals' management, where a need to optimize was found. 2) Shared care, which was lacking. 3) The relatives' role, which needs an extra focus.ConclusionRelatives experience insufficient palliative care mainly due to organizational and cultural problems among professionals. Palliative care in primary care in general needs improvement and attention should be drawn to the "professionalization" of the relatives and the need to strike a balance between their needs, wishes and resources in end-of-life care and bereavement.

Combined assay for two-hour identification of Streptococcus pneumoniae and Neisseria meningitidis and concomitant detection of 16S ribosomal DNA in cerebrospinal fluid by real-time PCR

The main object was to examine the diagnostic performance of a novel combination of a specific real-time PCR (combined real-time PCR) for immediate and simultaneous detection of Streptococcus pneumoniae and Neisseria meningitidis and of a real-time PCR of the 16S rRNA gene (16S DNA). During 12 months, 1015 routine CSF samples were consecutively collected from patients in the County of Aarhus, Denmark. The samples were cultured, examined by microscopy, and, in parallel, CSF DNA was automatically purified and subjected to real-time PCR. Melting curve analysis discriminated between the 2 specific pathogens and 16S DNA positive samples were sequenced. Clinical data were extracted from patients having positive samples. Clinically, 35 of 46 (76%) patients with positive samples had bacterial meningitis. 18 of these 35 patients had a concomitant culture and real-time PCR-positive sample. The remaining 17 patients were either culture positive (n =7) or real-time PCR-positive (n = 10). The aetiology of bacterial meningitis was revealed by microscopy in 18/35 (51.4%), culture in 24/35 (68.6%) and combined real-time PCR in 27/35 (77.1%) patients, respectively. In conclusion, the combined real-time PCR strategy is superior to microscopy and a valuable supplement to routine culture to establish the aetiology of bacterial meningitis.

Continuing medical education and burnout among Danish GPs

There has been minimal research into continuing medical education (CME) and its association with burnout among GPs. The aim of this study was to investigate the association between participating in CME and experiencing burnout in a sample of Danish GPs. Cross-sectional questionnaire study. All 458 active GPs in 2004, in the County of Aarhus, Denmark were invited to participate. Data on CME activities were obtained for all GPs and linked to burnout which was measured using the Maslach Burnout Inventory--Human Services Survey. The relationship between CME activity and burnout was calculated as prevalence ratios (PR) in a generalised linear model. In total, 379 (83.5%) GPs returned the questionnaire. The prevalence of burnout was about 25%, and almost 3% suffered from 'high burnout'. A total of 344 (92.0%) GPs were members of a CME group or a supervision group. Not being a member of either a CME group or a supervision group was statistically significantly associated with doubled likelihood of burnout (PR = 2.2). Among GPs not making use of a practice facilitator, a seven-fold higher likelihood of high burnout was found. GPs who were not members of a CME group and did not take part in outreach visits had a higher likelihood of suffering from burnout and high burnout than those who were members of a CME group or received outreach visits. Therefore, not being a member of a CME group could indicate that the GP is more likely to suffer from burnout. Although the present study does not unequivocally establish causality, it would be interesting to see whether staying active in CME may also prevent burnout among GPs.

A follow-up study of the occurrence and consequences of HbA1c measurements in an unselected cohort of non-pharmacologically treated patients with Type 2 diabetes

Objectives. To describe the occurrence of HbA1c measurements among non-pharmacologically treated diabetes patients, and to evaluate whether poor blood glucose regulation (HbA1c >8%) prompted intensification of treatment. Method. Data from the National Health Service Registry, the Regional Laboratory Database and the Danish National Hospital Registry were collected from 2002 to 2004 to identify and describe all Type 2 diabetic patients above 40 years of age in a background population of nearly 660 000 citizens in Aarhus County, corresponding to 12% of the total Danish population. Results. A total of 1989 had at least one HbA1c measurement, whereas 484 (20%) had no HbA1c measurement at all in 2003. Most patients had an HbA1c of less than 8%, and for 820 (41%) HbA1c was less than 6.5%, but for 316 (16%) patients, the first HbA1c measurement in 2003 was above 8%. After 6 months, patients with HbA1c above 8% had a higher probability of initiating pharmacological treatment (M; 0.64; 95% CI 0.58–0.70) (F; 0.68; 95% CI 0.58–0.77) than patients with HbA1c below 8% (M; 0.12; 95% CI 0.10–0.14) (F; 0.11; 95% CI 0.09–0.14). Conclusion. This study indicates that poor blood glucose regulation (HbA1c >8%) prompted a shift from non-pharmacological treatment to pharmacological treatment for most patients. However, a substantial group of patients are either not monitored on a regular basis or, if monitored, their elevated measurements of HbA1c do not prompt initiation of pharmacological treatment.

Complications related to blood donation: a population‐based study

Population-based data on the rate and outcome of complications related to blood donation are sparse. Data from a survey conducted in 2003 in Aarhus County, Denmark, were used to assess the overall rate of donor complications. Additional nationwide data on moderate and severe donor complications were obtained from the Danish Register of Complications Related to Blood Donation, with records of all moderate and severe donor complications in Denmark occurring during the period 1997-2003. In the regional survey, we identified 340 complications of any type among 41 274 donations, corresponding to a rate of 824/100,000 donations [95% confidence interval (CI): 741-916]. All complications were either needle injuries or vasovagal reactions. In the nationwide register, a total of 752 moderate and severe complications were recorded among 2,575,264 donations, corresponding to a rate of 29/100,000 donations (95% CI: 27-31). The rates of complications leading to long-term morbidity or disablement (> 5% loss of working capacity) were 5/100,000 donations (95% CI: 4.2-5.9) and 2.3/100,000 donations (95% CI: 1.8-2.9), respectively. The risk of complications related to blood donation is low. However, attention towards donor complications is warranted, given the non-negligible rate of complications resulting in long-term morbidity and disablement.

Are lifestyle changes achieved after participation in a screening programme for Type 2 diabetes? The ADDITION Study, Denmark

To examine the impact on health-related lifestyle of conducting a targeted stepwise diabetes screening programme. A total of 4731 people aged 40-69 years were offered stepwise diabetes screening in part of the Danish arm of the ADDITION-study in the county of Aarhus, Denmark. The screening comprised two main steps: identification of high-risk individuals by a mailed risk score questionnaire, and subsequent testing of high-risk individuals by their general practitioner. Questionnaires on physical exercise [International Physical Activity Questionnaire (IPAQ), short form], smoking habits and alcohol consumption were mailed to the target population 1 month prior to the offer of screening, and at 12 months' follow-up. At follow-up, additional questions regarding perceived changes in dietary habits, smoking, alcohol consumption and exercise were included. Three pairs of comparison groups were analysed. One year after screening, smokers who underwent further testing reduced smoking by one daily cigarette more than people at low risk of diabetes. The rate of smokers was not reduced, and the result was not confirmed by data regarding perceived change. Alcohol intake and exercise were unchanged. Data on perceived changes showed that more people undertook increased exercise in the group at low risk than in the further examined group, but this was not seen when comparing high-risk attenders with non-attenders. Dietary habits were unchanged, except that slightly more people in the group with an abnormal test result reported increase of fruit and vegetable intake and reduction of fat intake compared with the group with a normal test result. Only minor and inconsistent impacts on lifestyle was observed 1 year after screening.

Cost-effectiveness analysis of two management strategies for dyspepsia

To compare the cost-effectiveness of endoscopy and empirical proton pump inhibition (PPI) therapy for management of dyspepsia in primary care. A randomized controlled trial, including prospective collection of economic resource data, was conducted in general practice from June 2000 to August 2002, Aarhus County, Denmark. We randomly assigned 368 dyspeptic patients from thirty-two general practices to treatment with omeprazol 40 mg for 2 weeks (n=184) or endoscopy (n=184). The study adopted a societal perspective, and the year of costing was 2006. days free of dyspeptic symptoms and proportion of patients with dyspepsia after 1 year based on patients' and general practitioners' (GPs) assessment. Costs were estimated from patient and GP questionnaires and from medical records. The incremental cost-effectiveness (CE) ratio for 1 day free of dyspeptic symptoms using the endoscopy strategy was euro/day 154 compared with the PPI strategy. The incremental CE ratio for one person free of dyspeptic symptoms after 1 year using the endoscopy strategy was euro13,905 based on the patients' evaluation, and the incremental CE ratio for one person free of predominant symptoms after 1 year was euro5,990 according to the GPs' evaluation. The PPI strategy was both cheaper and more effective than the endoscopy strategy when reflux was the predominant symptom. A strategy using empirical antisecretory PPI therapy should be recommended if the alternative is an endoscopy strategy for managing dyspeptic patients in general practice, especially if reflux was the predominant symptom.

High prevalence of antibodies to Legionella spp. in Danish blood donors. A study in areas with high and average incidence of Legionnaires' disease

The incidence of Legionnaires' disease has an uneven geographical distribution in Denmark, ranging from 3 to 70 notified cases per million inhabitants per year in different towns. We investigated the prevalence of antibodies to Legionella in the one town with a consistently high incidence (Randers, Aarhus County) and compared it with that of an area of average incidence (Vejle, Vejle County). Blood samples were collected from healthy blood donors in Randers (n=308) and in Vejle (n=400), and analysed for antibodies to Legionella by indirect immunofluorescence antibody test with L. pneumophila, L. micdadei, and L. bozemanii as antigens. Overall 22.9% of the donors had antibody titres of > or = 1:128; indicating that antibodies to Legionella are common in healthy individuals, and reflecting that the bacteria may be widely distributed in the environment. Surprisingly, the study did not reveal a higher prevalence in the hyperendemic area. Thus, the high incidence of notified cases in this particular town may not be attributed to an overall increased exposure of the general population.
