Effect of hospital size and on-call arrangements on intrapartum and early neonatal mortality among low-risk newborns in Finland

Objective: To evaluate the influence of delivery unit size and on-call staffing in the performance of low-risk deliveries in Finland. Study design: A population-based study of hospital size and level based on Medical Birth Register data. Population was all hospital births in Finland in 2005-2009. Inclusion criteria were singleton births (birth weight 2500 g or more) without major congenital anomalies or birth defects. Additionally, only intrapartum stillbirths were included. Birthweights and maternal background characteristics were adjusted for by logistic regression. Main outcome measures were intrapartum or early neonatal mortality, neonatal asphyxia and newborns' need for intensive care or transfer to other hospital and longer duration of care. On-call arrangements were asked from each of the hospitals. Results: Intrapartum mortality was higher in units where physicians were at home when on-call (OR 1.25; 95% CI 1.02-1.52). A tendency to a higher mortality was also recorded in non-university hospitals (OR 1.18; 95% CI 0.99-1.40). Early neonatal mortality was twofold in units with less than 1000 births annually (OR 2.11; 95% CI 0.97-4.56) and in units where physicians were at home when on-call (OR 1.85; 95% CI 0.91-3.76). These results did not reach statistical significance. No differences between the units were found regarding Apgar scores or umbilical cord pH. Conclusion: The differences in mortality rates between different level hospitals suggest that adverse outcomes during delivery should be studied in detail in relation to hospital characteristics, such as size or level, and more international studies determining obstetric patient safety indicators are required.

The impact of increased number of low-risk deliveries on maternal and neonatal outcomes: A retrospective cohort study in Finland in 2011-2015

Objectives: Our aim was to demonstrate the influence of increased number of low-risk deliveries on obstetric and neonatal outcome. Study design: The study hospital was Katiloopisto Maternity Hospital in Helsinki. Simultaneously, we studied all three delivery units in the Helsinki region in the population-based analysis. The study population was singleton hospital deliveries occurring between 2011 and 2012, and 2014-2015. The study hospital included 11 237 and 15 637 births and the population-based group included 28 950 and 27 979 births. We compared outcome measures in different periods by calculating adjusted odds ratios (AOR). Main outcome measures were induced delivery, mode of delivery, third or fourth degree perinea, tear, Apgar score at five minutes 7 days, and perinatal death. Results: In the study hospital, induction rate increased from 22.4% to 24.8% (AOR 1.06, 95% CI; 1.00-1.12) while in the population-based analysis the rate decreased from 22.2% to 21.5% (AOR 0.96, 95% CI; 0.92-1.00). Percentage of neonatal transfers, low Apgar scores, and severe perineal tears increased both in study hospital and in population-based group. Changes in operative delivery rate and other adverse perinatal outcomes were statistically insignificant. Conclusions: Increasing the volume of a delivery unit does not compromise maternal or neonatal outcome. Specific characteristics of a delivery unit affect the volume outcome association.

Clinical Alarms in a Gynaecological Surgical Unit: A Retrospective Data Analysis

Alarm fatigue refers to the desensitisation of medical staff to patient monitor clinical alarms, which may lead to slower response time or total ignorance of alarms and thereby affects patient safety. The reasons behind alarm fatigue are complex; the main contributing factors include the high number of alarms and the poor positive predictive value of alarms. The study was performed in the Surgery and Anaesthesia Unit of the Women’s Hospital, Helsinki, by collecting data from patient monitoring device clinical alarms and patient characteristics from surgical operations. We descriptively analysed the data and statistically analysed the differences in alarm types between weekdays and weekends, using chi-squared, for a total of eight monitors with 562 patients. The most common operational procedure was caesarean section, of which 149 were performed (15.7%). Statistically significant differences existed in alarm types and procedures between weekdays and weekends. The number of alarms produced was 11.7 per patient. In total, 4698 (71.5%) alarms were technical and 1873 (28.5%) were physiological. The most common physiological alarm type was low pulse oximetry, with a total of 437 (23.3%). Of all the alarms, the number of alarms either acknowledged or silenced was 1234 (18.8%). A notable phenomenon in the study unit was alarm fatigue. Greater customisation of patient monitors for different settings is needed to reduce the number of alarms that do not have clinical significance

Maternal age and risk of cesarean section in women with induced labor at term - a Nordic register-based study

Abstract Introduction Over the last decades, induction of labor has increased in many countries along with increasing maternal age. We assessed the effects of maternal age and labor induction on cesarean section at term among nulliparous and multiparous women without previous cesarean section. Material and methods We performed a retrospective national registry-based study from Denmark, Finland, Iceland, Norway and Sweden including 3 398 586 deliveries between 2000 and 2011. We investigated the impact of age on cesarean section among 196 220 nulliparous and 188 158 multiparous women whose labor was induced, had single cephalic presentation at term and no previous cesarean section. Confounders comprised country, time-period and gestational age. Results In nulliparous women with induced labor the rate of cesarean section increased from 14.0% in women less than 20 years of age to 39.9% in women 40 years and older. Compared to women aged 25-29 years, the corresponding relative risk were 0.60 (95% confidence interval (CI); 0.57 to 0.64) and 1.72 (95% CI; 1.66 to 1.79). In multiparous induced women the risk of cesarean section was 3.9% in women less than 20 years rising to 9.1% in women 40 years and older. Compared to women aged 25-29 years, the relative risk were 0.86 (95% CI; 0.54 to 1.37) and 1.98 (95% CI; 1.84 to 2.12), respectively. There were minimal confounding effects of country, time-period and gestational age on risk for cesarean section. Conclusions Advanced maternal age is associated with increased risk of cesarean section in women undergoing labor induction with a single cephalic presentation at term without a previous cesarean section. The absolute risk of cesarean section is 3-5 times higher across 5-year age groups in nulliparous relative to multiparous women having induced labor.Peer reviewe
