- ObjectiveTo study the predictive value of biphasic ST-events for interventions for suspected fetal distress and adverse neonatal outcome, when using ST-analysis of the fetal electrocardiogram (FECG) for intrapartum fetal monitoring. DesignProspective cohort study. SettingThree academic hospitals in Sweden. PopulationWomen in labor with a high-risk singleton fetus in cephalic position beyond 36weeks of gestation. MethodsIn women in labor who were monitored with conventional cardiotocography, ST-waveform analysis was recorded and concealed. Traces with biphasic ST-events of the FECG (index) were compared with traces without biphasic events of the FECG. The ability of biphasic events to predict interventions for suspected fetal distress and adverse outcome was assessed using univariable and multivariable logistic regression analyses. Main outcome measuresInterventions for suspected fetal distress and adverse outcome (defined as presence of metabolic acidosis (i.e. umbilical cord pH <7.05 and base deficit in extracellular fluid >12mmol), umbilical cord pH <7.00, 5-min Apgar score <7, admittance to neonatal intensive care unit or perinatal death). ResultsAlthough the presence of biphasic events of the FECG was associated with more interventions for fetal distress and an increased risk of adverse outcome compared with cases with no biphasic events, the presence of significant (i.e. intervention advised according to cardiotocography interpretation) biphasic events showed no independent association with interventions for fetal distress [odds ratio (OR) 1.71, 95% confidence interval (CI) 0.65-4.50] or adverse outcome (OR 1.96, 95% CI 0.74-5.24). ConclusionThe presence of significant biphasic events did not discriminate in the prediction of interventions for fetal distress or adverse outcome. Therefore, biphasic events in relation to ST-analysis monitoring during birth should be omitted if future studies confirm our findings.

- BackgroundIn publicly funded health care systems, governance models are developed to push public service providers to use tax payers' money more efficiently and maintain a high quality of service. Although this implies change in staff behaviors, evaluation studies commonly focus on organizational outputs. Unintended consequences for staff have been observed in case studies, but theoretical and methodological development is necessary to enable studies of staff experience in larger populations across various settings. The aim of the study is to develop a self-assessment scale of staff experience of the governance of economic efficiency and quality of health care and to assess its psychometric properties.MethodsFactors relevant to staff members' experience of economic efficiency and quality requirements of health care were identified in the literature and through interviews with practitioners, and then compared to a theoretical model of behavior change. Relevant experiences were developed into sub-factors and items. The scale was tested in collaboration with the Department of Rehabilitation Medicine at a university hospital. 93 staff members participated. The scale's psychometric properties were assessed using exploratory factor analysis, analysis of internal consistency and criterion-related validity.ResultsThe analysis revealed an eight factor structure (including sub-factors knowledge and awareness, opportunity to influence, motivation, impact on professional autonomy and organizational alignment), and items showed strong factor loadings and high internal consistency within sub-factors. Sub-factors were interrelated and contributed to the prediction of impact on clinical behavior (criterion).ConclusionsThe scale clearly distinguishes between various experiences regarding economic efficiency and quality requirements among health care staff, and shows satisfactory psychometric quality. The scale has broad applications for research and practice, as it serves as a tool for capturing staff members' perspectives when evaluating and improving health care governance. The scale could also be useful for understanding the underlying processes of changes in provider performance and for adapting management strategies to engage staff in driving change that contributes to increased economic efficiency and quality, for the benefit of health care systems, patients and staff.

- OBJECTIVE: The purpose of this study was to assess the effectiveness of electronic fetal monitoring (EFM) alone and with additional ST analysis (EFM + ST) in laboring women with a singleton term pregnancy that is in cephalic presentation in the prevention of metabolic acidosis by the application of individual patient data metaanalysis. STUDY DESIGN: We conducted an individual patient data metaanalysis using data from 4 randomized trials, which enabled us to account for missing data and investigate relevant subgroups. The primary outcome was metabolic acidosis, which was defined as an umbilical cord-artery pH <7.05 and a base deficit that had been calculated in the extra cellular fluid compartment >12 mmol/L. We performed 8 explanatory subgroup analyses for 8 different endpoints. RESULTS: We analyzed data from 12,987 women and their newborn infants. Metabolic acidosis was present in 57 women (0.9%) in the EFM + ST group and 73 women (1.1%) in the EFM alone group (relative risk [RR], 0.76; 95% CI, 0.53-1.10). Compared with EFM alone, the use of EFM + ST resulted in a reduction in the frequency of instrumental vaginal deliveries (RR, 0.90; 95% CI, 0.83-0.99) and fetal blood samples (RR, 0.49; 95% CI, 0.44-0.55). Cesarean delivery rates were comparable between both groups (RR, 0.99; 95% CI, 0.91-1.09). Subgroup analyses showed that EFM + ST resulted in fewer admissions to a neonatal intensive care unit for women with a duration of pregnancy of >41 weeks (RR, 0.61; 95% CI, 0.39-0.95). CONCLUSION: EFM + ST does not reduce the risk of metabolic acidosis, but it does reduce the need for instrumental vaginal deliveries and fetal blood sampling.

- Objectives: The aim of this study was to investigate the potential impact of gestational age (GA) estimation on the basis of the last menstrual period (LMP) in comparison with GA based on ultrasound examination on rates of survival and neonatal morbidity among extremely preterm infants. Methods: The Swedish national registry of infants born extremely preterm (Extremely Preterm Infants in Sweden Study), including infants born before 27 weeks of gestation, was used to identify 645 infants with available information. Incidences of stillbirth, survival, small for GA (SGA), and major neonatal morbidity were calculated in relationship to the GA estimated by each of the approaches. Results: Pregnancies, in general, appeared to be longer when GA was estimated by LMP than by ultrasound (17.2% of the pregnancies were longer than 27 weeks). The incidences of stillbirth, neonatal death, and major neonatal morbidity in relationship to GA were similar for both groups. The risks for SGA were elevated when GA according to ultrasound examination was at least 7 days shorter than GA based on the LMP. Conclusions: In our cohort of infants born extremely preterm, estimation of GA on the basis of LMP indicated a longer pregnancy than estimated by ultrasound but did not influence the incidences of neonatal survival and morbidity.

Value-Based Reimbursement in Collectively Financed Healthcare Requires Monitoring of Socioeconomic Patient Data to Maintain Equality in Service Provision

Tidskriftsartikel (refereegranskat)abstract
- Value-based purchasing is increasingly discussed in association with efforts to develop modern healthcare systems. These models are the most recent example of models derived from health economics research intended to reform collectively financed healthcare. Previous examples have ranged from creation of pseudo-markets to opening these markets for competition between publicly and privately owned enterprises. Most value-based purchasing models tend to ignore that health service provision in collectively financed settings is based on an insurance with political, social obligations attached that challenge the notion of free market and individualist premises which these models rest on. Central social issues related to healthcare in any modern complex society, such as inequality in service provision, can all too easily disappear in value-based reform efforts. Based on an analysis of Swedish policy development, we contend that management information systems need to be extended to allow routine monitoring of socioeconomic data when models such as value-based purchasing are introduced in collectively financed health services. The experiences from Sweden are important for health policy in Europe and other regions with collectively financed healthcare plans.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To determine the prevalence and types of intrapartum cardiotocography (CTG) patterns and investigate their relationship to moderate acidemia in term fetuses of diabetic mothers. Also, to assess if the combination of fetal electrocardiogram (FECG) and those CTG patterns strengthens the association with moderate acidemia. Material and methods: The material for this study is obtained from the Swedish randomized control trial and the European Union ST-analysis trial. We developed an analytical model for CTG patterns based on the progress in CTG changes, in a longitudinal periodic manner. The model was then combined with information regarding changes in ST interval that indicate threatening asphyxia, and the findings were analyzed to determine correlation with the presence of moderate acidemia at birth. Results: This study involved data of 413 diabetic mothers. A preterminal CTG was more common in the diabetes mellitus (DM) group (6/70, 8.6%) than in the gestational diabetes (GD) group (3/307, 1.0%; P=0.003). For diabetic mothers (i.e., DM+GD) with a normal CTG at the start of monitoring, the presence of FECG data indicating asphyxia significantly increased the likelihood of an umbilical artery pH < 7.15 at birth wodds ratio (OR) = 3.65, 95% confidence interval (CI) = 1.33-10.05]. Among labors where the CTG was non-reassuring at the start of monitoring, no significant association was found between pH < 7.15 and indication to intervene according to FECG information (OR = 1.51, 95% CI = 0.33-7.0). Conclusions: A preterminal CTG is more common in the fetuses of DM than GD mothers during labor. When CTG was normal at the start of recording, the addition of FECG information gave a significant add on information to predict moderate acidemia.
