Objectives The objectives of this study were to (i) identify transient risk factors of occupational injuries and (ii) determine if the risk varies with age, injury severity, job task, and industry risk level. Method A case-crossover design was used to examine the effect of seven specific transient risk factors (time pressure, disagreement with someone, feeling sick, being distracted by someone, non-routine task, altered surroundings, and broken machinery and materials) for occupational injuries. In the study, 1693 patients with occupational injuries were recruited from a total of 4002 occupational injuries seen in 2013 at two emergency departments in Denmark. Effect estimates were calculated using the matched-pair interval approach. Results Increased risk for an occupational injury was found for time pressure [odds ratio (OR) 1.6, 95% confidence interval (95% CI) 1.3–2.0], feeling sick (OR 2.7, 95% CI 1.9–3.9), being distracted by someone (OR 3.1, 95% CI 2.3–4.1), non-routine task (OR 8.2, 95% CI 5.3–12.5), altered surroundings (OR 20.9, 95% CI 12.2–35.8), and broken machinery or materials (OR 20.6, 95% CI 13.5–31.7). The risk of occupational injury did not vary substantially in relation to sex, age, job task, industry risk level, or injury severity. Conclusion Use of a case-crossover design identified several worker-related transient risk factors (time pressure, feeling sick, being distracted by someone) that led to significantly increased risks for occupational injuries. In particular, equipment (broken machinery or materials) and work-practice-related factors (non-routine task and altered surroundings) increased the risk of an occupational injury. Elaboration of results in relation to hazard period and information bias is warranted. © 2017, Nordic Association of Occupational Safety and Health. All rights reserved.

Objective: Missing data is a ubiquitous problem in studies using patient-reported measures, decreasing sample sizes and causing possible bias. In longitudinal studies, special problems relate to attrition and death during follow-up. We describe a methodological approach for the use of multiple imputation (MI) to meet these challenges.Methods: In a cohort of patients treated with percutaneous coronary intervention followed with use of repetitive questionnaires and information from national registers over 3 years, only 417 out of 1,726 patients had complete data on all measure points and covariates. We suggest strategies for use of MI and different methods for dealing with death along with sensitivity analysis of deviations from the assumption of missing at random, all with the use of standard statistical software. The Mental Component Summary from Short Form 12-item survey was used as an example.Conclusion: Ignoring missing data may cause bias of unknown size and direction in longitudinal studies. We have illustrated that MI is a feasible method to try to deal with bias due to missing data in longitudinal studies, including attrition and nonresponse, and should be considered in combination with analysis of sensitivity in longitudinal studies. How to handle dropout due to death is still open for debate. © 2015 Biering et al.

Purpose-To compare the risks of re-admission, reoperation, and mortality within 90 days of surgery in orthopedic departments with well-documented fast-track arthroplasty programs with those in all other orthopedic departments in Denmark from 2005 to 2011. Methods-We used the Danish hip and knee arthroplasty registers to identify patients with primary total hip arthroplasty or total knee arthroplasty. Information about re-admission, reoperation, and mortality within 90 days of surgery was obtained from administrative databases. The fast-track cohort consisted of 6 departments. The national comparison cohort consisted of all other orthopedic departments. Regression methods were used to calculate relative risk (RR) of adverse events, adjusting for age, sex, type of fixation, and comorbidity. Cohorts were divided into 3 time periods: 2005-2007, 2008-2009, and 2010-2011. Results-79,098 arthroplasties were included: 17,284 in the fast-track cohort and 61,814 in the national cohort. Median length of stay (LOS) was less for the fast-track cohort in all 3 time periods (4, 3, and 3 days as opposed to 6, 4, and 3 days). RR of re-admission due to infection was higher in the fast-track cohort in 2005-2007 (1.3, 95% CI: 1.1-1.6) than in the national cohort in the same time period. This was mainly due to urinary tract infections. RR of re-admission due to a thromboembolic event was lower in the fast-track cohort in 2010-2011 (0.7, CI: 0.6-0.9) than in the national cohort in the same time period. No differences were seen in the risk of reoperation and mortality between the 2 cohorts during any time period. Interpretation-The general reduction in LOS indicates that fast-track arthroplasty programs have been widely implemented in Denmark. At the same time, it appears that dedicated fasttrack departments have been able to optimize the fast-track program further without any rise in re-admission, reoperation, and mortality rates.

Objective: Improvements in the treatment of coronary heart disease have increased the number of patients living with a chronic heart disease. Patient-reported outcomes are required to adequately describe prognosis. We report self-rated health in a population-based cohort of patients with coronary heart disease treated with percutaneous coronary intervention (PCI). Methods: Over 3 years, we followed 1,726 patients under 65 years treated with PCI with eight repetitive questionnaires. With the use of multiple imputation, we described the course of self-rated health using the short form 12-item survey’s mental component summary (MCS) and physical component summary (PCS) and analyzed adjusted differences by sex, age, educational level, indication for PCI, and left ventricular ejection fraction along with an analysis of decrease in health status. Results: MCS scores increased during follow-up, while PCS scores were stable over time. Men rated higher in MCS and PCS than women, and older patients rated higher in MCS than younger. Other differences were negligible. Younger age was identifed as a risk factor for marked decrease in mental health over time. Conclusion: In a complete population-based cohort of PCI patients with multiple measurements, we found improvements in mental, but not physical health over time. Demographic differences in health were larger than disease-related differences. © 2014 Biering et al.

Objective: A relation may exist between self-reported health and adverse events in coronary heart disease. Previous studies have been vulnerable to possible selection bias. In the study reported here, we examined the association between self-rated health and adverse events in terms of cardiac events, cardiac readmissions, and all-cause mortality in a complete cohort of patients treated with percutaneous coronary intervention (PCI). Study design and setting: A cohort of patients with coronary heart disease treated with PCI was followed up with questionnaires 4 weeks after PCI to measure self-rated health and in registers to identify adverse events. Of 1,752 eligible patients under 67 years, 26 died during the first 4 weeks. A total of 224 patients were excluded from the analysis because they were readmitted with a cardiac diagnosis before answering the first questionnaire. We received complete SF-12 Health Survey component summaries from 984 of the remaining 1,502 patients. We used multiple imputation to establish a complete cohort, including nonrespondents. Results: During follow-up, 83 patients died, 220 patients experienced a new cardiac event, and 526 patients experienced a hospital readmission related to coronary heart disease. Poor self-rated health was related to cardiac events, cardiac readmission, and all-cause mortality. The associations were stronger for all-cause mortality than for events and readmissions. Physical health was more important than mental health, but both revealed an exposure-response pattern. Conclusion: Poor self-reported health within 4 weeks of PCI was associated with adverse outcomes during up to 5 years' follow-up. © 2014 Biering et al.

Objective To describe conditions regarding hysterectomy for benign indications during the past 35 years in Denmark. Study design Population-based register study of 167,802 women who underwent hysterectomy for benign conditions in the period 1977-2011. Patient data regarding operative techniques, hospitalization, indications, patient age, and geography were extracted from the Danish National Patient Register. Results The overall rate of hysterectomy was around 180/100,000 woman years during the period. A rise in laparoscopic and vaginal hysterectomy was seen at the expense of abdominal hysterectomy. The indication of pelvic organ prolapse and abnormal uterine bleeding increased while the indication of fibroids decreased. The average age of women at time of hysterectomy increased from 46 years in 1977-1981 to 50 years in 2006-2011. The mean number of hospitalization days was reduced by 75%. Regional differences were detected regarding route of hysterectomy and hospitalization. Conclusions This study demonstrates a change in the pattern of indications for hysterectomy, increased age of the affected women, reduced length of stay in the hospital, and a rise in the percentage of minimal invasive surgical procedures. © 2013 Elsevier Ireland Ltd © 2013 Published by Elsevier Ireland Ltd.

Stroke | Year: 2014
Background and Purpose-Preadmission oral anticoagulant treatment (OAT) has been linked with less severe stroke and a better outcome in patients with atrial fibrillation. However, the existing studies have methodological limitations and have, with one exception, not included hemorrhagic strokes. We performed a nationwide historic follow-up study using data from population-based healthcare registries to assess the effect of preadmission OAT on stroke outcomes further. Methods-We identified 11 356 patients with atrial fibrillation admitted to hospital with acute stroke (including ischemic stroke and intracerebral hemorrhage) between 2003 and 2009. Propensity score-matched analyses were used to compare stroke severity (Scandinavian Stroke Scale score) and mortality among 2175 patients with preadmission OAT and 2175 patients without preadmission OAT. Results-A total of 2492 (21.9%) patients received OAT at the time of their stroke. Preadmission OAT was associated with a lower risk of severe stroke (Scandinavian Stroke Scale score at time of admission, <30 point; propensity score-matched odds ratio, 0.74; 95% confidence interval, 0.63-0.86) and lower 30-day mortality rate (propensity score-matched adjusted odds ratio, 0.83; 95% confidence interval, 0.71-0.98). Conclusions-Only a minority of hospitalized patients with acute stroke with atrial fibrillation received OAT at the time of stroke. Preadmission OAT was associated with less severe stroke and lower 30-day mortality rate in a propensity score-matched analysis. © 2013 American Heart Association, Inc.

In a Danish Interprofessional Training Unit (ITU), the clinical tutors have succeeded in developing a safe learning environment combined with challenging the students by giving them responsibility for the patient's care and rehabilitation. In the ITU, students improved their uniprofessional and interprofessional knowledge and capability while strengthening their professional identity. It was, therefore, decided to make an attempt to transfer these interprofessional learning and teaching methods to another setting. The aims of this study were to evaluate whether the students learned about interprofessional collaboration and strengthened their professional identity and whether the clinical tutors could create a safe and challenging learning environment. Clinical tutors from the professions occupational therapy, physiotherapy, and nursing together planned the pedagogical approach and practical organization of two pilot studies in an orthopedic ward. After the intervention, focus group interviews of students and clinical tutors were performed and analyzed. The findings indicated that a one-week interprofessional clinical placement can contribute to students learning about interprofessional collaboration and to their development of professional identity. The data from the clinical tutors indicated that they needed to create a safe and challenging learning environment but emphasized that a thorough planning and continuous monitoring and adjusting of the clinical placement is necessary for success. The study documents that it is possible to create successful interprofessional learning opportunities in a normal ward environment in a restricted time frame. This knowledge can be applied to other ward settings where interprofessional clinical training is a natural possibility. © 2014 Informa UK Ltd.

Q fever is a zoonotic infection which can pose a danger to pregnant women. To our knowledge, Denmark has never experienced a clinically verified Q fever outbreak. We aimed to quantify risk of infection in pregnant women occupationally and environmentally exposed to Coxiella burnetii. The Danish National Birth Cohort collected blood samples from 100,418 pregnant women in the period 1996 to 2002. We sampled 195 women with occupational exposure to livestock (veterinarians and female farmers), 202 women with domestic exposure (dairy cattle and/or sheep) and a random sample of 459 unexposed women. Samples were screened for antibodies against C. burnetii by commercial enzyme-linked immunosorbent assay. Positive samples were confirmed by immunofluorescence (cut-off titre ≥1:128). The proportion of seropositive women was higher in the occupationally exposed (47.2% seropositive; relative risk (RR): 9.8; 95% confidence interval (CI): 6.4-15.2) and the domestically exposed population (32.2% seropositive; RR: 6.7; 95% CI: 4.3-10.6) than in unexposed women (4.8% seropositive). We found a high prevalence of antibodies to C. burnetii among pregnant women with occupational or domestic exposure to cattle and/or sheep compared with unexposed pregnant women. Our findings suggest that contact to livestock is a risk factor for C. burnetii infection in Denmark.

Background/objective:Information on weight loss is used in screening and assessment tools. It is essential that the data are correct. Anamnestic data of weight changes were compared with records for hospitalized patients and outpatients.Subjects/methods:For hospitalized patients, anamnestic and recorded weight data were obtained. For outpatients, data of weight changes since last visit were obtained.Results:Of 34 hospitalized patients, 21 stated change of weight (15 lost, 6 gained). Weight loss in 9 and weight gain in 12 patients were recorded. Ten patients stated no change of weight. Weight loss in 4 and weight gain in 3 patients were recorded. Of 15 patients who stated weight loss, it was correct for 9 patients. Six of 21 patients stated weight changes opposite the records. Of 43 patients, 14 stated weight changes before admission; only 9 could indicate the time span. Ten patients stated 'Do not know' to the question of weight changes. For 156 outpatients, 86 stated change of weight (39 lost, 47 gained). Weight loss in 42 and weight gain in 47 patients were recorded. Fifty-eight patients stated no change of weight. Weight loss in 26 and weight gain in 29 patients were recorded. Of 38 patients who stated weight loss, it was correct for 31. Seventeen of 85 patients stated weight changes opposite the records.Conclusions:Recollection of weight changes is poor for a large percentage of patients. In patients who stated weight loss it was only correct for 75%, and for patients who stated unchanged weight 25% have lost more than 1 kg. Thus, incorrect weight loss data can cause over- and underestimation of nutritional risk. © 2013 Macmillan Publishers Limited All rights reserved.
