Introduction Studies indicate an association between errors in cardiotocography (CTG) management and hypoxic brain injuries among newborns. Continuing professional education is recommended. We aimed to examine whether the implementation of a national interprofessional CTG education program in Denmark was associated with a decrease in risk of fetal hypoxia measured by umbilical cord pH < 7.00, 5‐minute Apgar score <7 or neonatal therapeutic hypothermia. As a secondary aim, we assessed whether the educational intervention was associated with an increase in operative deliveries. Material and methods We conducted a historical cohort study from 2009 to 2015 including all intended vaginal deliveries with liveborn singletons in cephalic presentation and gestational age ≥37 weeks. Data were retrieved from the Medical Birth Register and the National Patient Register. The study period was divided in three: pre‐implementation (2009‐2012), implementation (2013) and post‐implementation (2014‐2015). Using logistic regression we estimated odds ratios (OR) of fetal hypoxia outcomes using the pre‐implementation period as reference. Analyses were adjusted for potential maternal, neonatal and delivery‐associated confounders. Missing data were accounted for by multiple imputation. Results In all, 331 282 deliveries were included. Overall risks of pH < 7.00, Apgar score <7 and therapeutic hypothermia were respectively 0.45%, 0.58% and 0.06%. Adjusted OR in the post‐implementation period were 1.12 (95% confidence interval [CI] 1.00‐1.26), 0.99 (95% CI 0.90‐1.10) and 1.34 (95% CI 0.99‐1.82) for the three outcomes, respectively. The pH missingness equaled 12.4%. Odds of emergency cesarean section was unaltered, whereas the odds of assisted vaginal delivery decreased by 14% (0.86, 95% CI 0.84‐0.89). Conclusions Healthcare professionals are considered the weakest link of CTG technology. We did not find that increasing healthcare professionals’ CTG interpretation skills affected the risk of fetal hypoxia. Missing data for pH values were substantial and represent a limitation of the study. We cannot with certainty rule out that missingness masked a true effect of the intervention. Our study indicates that assisted vaginal deliveries can be decreased without an increased risk of fetal hypoxia. Dilution of effect in a complex clinical setting, rare outcomes, insufficient intervention and a possible overestimation of the impact of errors in CTG management might explain the lack of effect.

BackgroundTo reduce the incidence of hypoxic brain injuries among newborns a national cardiotocography (CTG) education program was implemented in Denmark. A multiple-choice question test was integrated as part of the program. The aim of this article was to describe and discuss the test development process and to introduce a feasible method for written test development in general.MethodsThe test development was based on the unitary approach to validity. The process involved national consensus on learning objectives, standardized item writing, pilot testing, sensitivity analyses, standard setting and evaluation of psychometric properties using Item Response Theory models. Test responses and feedback from midwives, specialists and residents in obstetrics and gynecology, and medical and midwifery students were used in the process (proofreaders n = 6, pilot test participants n = 118, CTG course participants n = 1679).ResultsThe final test included 30 items and the passing score was established at 25 correct answers. All items fitted a loglinear Rasch model and the test was able to discriminate levels of competence. Seven items revealed differential item functioning in relation to profession and geographical regions, which means the test is not suitable for measuring differences between midwives and physicians or differences across regions. In the setting of pilot testing Cronbach’s alpha equaled 0.79, whereas Cronbach’s alpha equaled 0.63 in the setting of the CTG education program. This indicates a need for more items and items with a higher degree of difficulty in the test, and illuminates the importance of context when discussing validity.ConclusionsTest development is a complex and time-consuming process. The unitary approach to validity was a useful and applicable tool for development of a CTG written assessment. The process and findings supported our proposed interpretation of the assessment as measuring CTG knowledge and interpretive skills. However, for the test to function as a high-stake assessment a higher reliability is required.Electronic supplementary materialThe online version of this article (doi:10.1186/s12909-017-0915-2) contains supplementary material, which is available to authorized users.

Content and construct validity and reliability were acceptable. The presented template for the development of this MCQ test could be useful to others when developing knowledge tests and may enhance the overall quality of test development.

National consensus on CTG learning objectives was achieved using the Delphi methodology. This was an initial step in developing a valid CTG education program. A prioritized list of objectives will clarify which topics to emphasize in a CTG education program.

CTG knowledge, interpretation skills and decision-making measured by a written assessment were positively associated with working in large maternity units and having < 15 years of obstetric work experience. This might indicate a challenge in maintaining CTG skills in small units and among experienced staff but could also reflect different levels of motivation, test familiarity and learning culture. Whether the findings are transferable to the clinical setting was not examined.

BackgroundComplex treatment, care and rehabilitation require continuous healthcare professional development and maintenance of competencies in collaboration with other professionals. Interprofessional education in childhood cancer involves several groups of healthcare professionals with both general and specific knowledge and skills.ObjectiveTo establish consensus on content and interprofessional learning objectives for an interprofessional education in childhood cancer.DesignA three-round Delphi survey in Scandinavian childhood cancer departments.ParticipantsHealthcare professionals appointed by their head of departments and head nurses based on their profession and their involvement in continuing professional development.Main outcome measuresA prioritised list of interprofessional learning objectives with a mean score of ≥3 on a five-point scale (1=not relevant, 5=extremely relevant).Results12 childhood cancer departments participated with 30 healthcare professionals: 11 nurses, 10 medical doctors, 5 social workers, 2 physiotherapists and 2 pedagogues. In total, 28 (93%), 25 (83%) and 22 (73%) completed the first, second and third round, respectively. In the first round, we asked open-ended questions and used directed content analysis to analyse 386 statements. We formulated 170 interprofessional learning objectives in six categories: (1) acute life-threatening situations, (2) gastrointestinal toxicities and side effects, (3) pain, (4) palliation, (5) play and activity, and (6) prescription and administration of medicine. The second round resulted in 168 interprofessional learning objectives receiving a mean score of ≥3 on a five-point scale. Final agreement in the third round resulted in a prioritised list of 168 learning objectives.ConclusionsConsensus on content and interprofessional learning objectives for an interprofessional education in childhood cancer was established across five groups of healthcare professionals in three countries. Some learning objectives are generic and can be applied in settings other than childhood cancer, where healthcare professionals collaborate to provide patients and families optimal treatment and care.

Introduction: In high-income countries the majority of pregnancies have a good outcome, and many adverse obstetric outcomes rarely occur. This makes demonstrating clinically relevant and statistically significant effects of new interventions a challenge. The objective of the study was to report incidences of important obstetric outcomes and to calculate sample sizes for tentative studies. Material and methods: The study was a registry-based study. Data were retrieved from the Danish Medical Birth Registry and included all deliveries in Denmark from 2008 to 2015. The total population included 465 919 deliveries. The study population comprised intended vaginal deliveries with a single fetus in cephalic presentation at term (n = 381 567). Incidences were reported for 20 outcomes considering the relevance for the patients and the severity of the outcomes. We calculated the sample sizes required in tentative obstetric studies to detect risk reductions of 25 and 50%, for tests at the 5% level, using a power of 80 and 90%. For the randomized controlled trials we calculated the sample size required for comparing two proportions with equal-sized groups. For the cohort study we calculated the sample size also required for two proportions but with unequal sized groups. Outcome measures for sample size calculation were neonatal mortality, Apgar score <7 at 5 minutes and emergency cesarean section. Results: The incidence of neonatal mortality, Apgar score <7 at 5 minutes and emergency cesarean section was 0.05, 0.58 and 10.5%, respectively. Using neonatal mortality as the outcome in a tentative randomized controlled trial with an expected risk reduction of 50% and power of 80%, our calculation showed a sample size of 195 036 deliveries. Using Apgar score <7 at 5 minutes or emergency cesarean section as the outcome, 16 254 and 818 deliveries, respectively, were required. In tentative cohort studies, the required sample sizes were larger due to the unequal proportion of exposed/non-exposed women. Conclusions: Most adverse obstetric outcomes occur rarely; thus, very large sample sizes are required to achieve adequate statistical power in randomized controlled This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
