How common is substandard obstetric care in adverse events of birth asphyxia, shoulder dystocia and postpartum hemorrhage? Findings from an external inspection of Norwegian maternity units

Maternal and neonatal complications of shoulder dystocia with a focus on obstetric maneuvers: A case-control study of 1103 deliveries

INTRODUCTION

Shoulder dystocia is a severe obstetric emergency that can cause substantial neonatal and maternal complications. This study aims to assess the performed obstetric maneuvers and their frequency, success, and association with maternal and neonatal complication rates.

MATERIAL AND METHODS

The study population was collected among all deliveries in the Hospital District of Helsinki and Uusimaa between 2006 and 2015 (n = 181 352) by searching for ICD-10 codes for shoulder dystocia, brachial plexus injury and clavicle fracture. Shoulder dystocia cases (n = 537) were identified by reviewing the medical records. Shoulder dystocia cases treated with one or two maneuvers were compared with those treated with at least three. Medical records of a matched control group constituting of 566 parturients without any of the forementioned ICD-10 codes were also scrutinized.

RESULTS

Using the four most common obstetric maneuvers (McRoberts maneuver, suprapubic pressure, rotational maneuvers, the delivery of the posterior arm) significantly increased during the study period with individual success rates of 61.0%, 71.9%, 68.1% and 84.8%, respectively. Concurrently, the rate of brachial plexus injury and combined neonatal morbidity significantly declined from 50% to 24.2% (p = 0.02) and from 91.4% to 48.5% (p < 0.001). Approximately 75% of shoulder dystocia cases treated with maneuvers were resolved by the McRoberts maneuver and/or suprapubic pressure, but each of the four most performed maneuvers significantly increased the cumulative success rate individually and statistically (p < 0.001). The rates of brachial plexus injury and combined neonatal morbidity were at their highest (52.9% and 97.8%) when none of the maneuvers were performed and at their lowest when two maneuvers were performed (43.0% and 65.4%). The increasing number (≥3) of maneuvers did not affect the combined maternal or neonatal morbidity or brachial plexus injury but increased the risk for third- or fourth-degree lacerations (odds ratio 2.91, 95% confidence interval 1.17 to 7.24).

CONCLUSIONS

The increased use of obstetric maneuvers during the study period was associated with decreasing rates of neonatal complications; conversely, the lack of obstetric maneuvers was associated with the highest rate of neonatal complications. These emphasize the importance of education, maneuver training and urgently performing shoulder dystocia maneuvers according to the international protocol guidelines.

Trends in severe postpartum haemorrhage among nulliparous women with spontaneous onset of labour: A population-based cohort study

OBJECTIVE

To investigate the incidence of severe postpartum haemorrhage among nulliparous women with a spontaneous onset of labour at term from 2000 to 2020.

DESIGN

Population-based cohort study.

SETTING

National, using the Medical Birth Registry of Norway.

POPULATION

Women (n = 330 244) who gave birth to their first singleton child in a cephalic presentation after a spontaneous onset of labour at term.

METHODS

Cross-tabulations and regression analysis with generalised linear models were used to assess time trends and adjust for potential confounding factors. We also stratified the analyses by maternal age groups, obstetric interventions, mode of delivery and institution size. Time trends were analysed using periods of 5 or 6 years as a unit, and the period from 2000 to 2004 was used as the reference.

MAIN OUTCOME MEASURES

Severe postpartum haemorrhage (PPH) was defined as blood loss of >1500 mL within 24 h and/or in combination with blood transfusion.

RESULTS

Severe PPH occurred in 7601/330 244 (2.30%) women. The incidence increased from 1.24% in 2000-2004 to 3.83% in 2015-2020 (adjusted relative risk, aRR 2.90; 95% CI 2.70-3.12). Changes in maternal characteristics or obstetric interventions did not explain the increase, and we found similar increases across institutions of all sizes.

CONCLUSIONS

The incidence of severe PPH among nulliparous women increased almost threefold over 21 years. The current high incidence warrants urgent efforts to assess unknown risk factors, the health care provided and health system factors that may contribute to the increase, to inform improvements in care.

Obstetric claims in Finland 2012-2022-A nationwide patient insurance registry study

INTRODUCTION

Maternal and infant mortality rates in Finland are among the lowest in the world, yet preventable obstetric injuries occur every year. The aim of this study was to describe obstetric claims, their compensation rates, and temporal trends of claims reported to the Patient Insurance center.

MATERIAL AND METHODS

A nationwide, register-based study was conducted. Data consisted of obstetric claims reported to the Patient Insurance Center between 2012 and 2022. Data analyzed included the year of injury, compensation criteria, maternal age, birth hospital, delivery method, reported causes of injury, and maternal or neonatal injury. The data were analyzed with descriptive statistics and logistic regression models.

RESULTS

A total of n = 849 obstetric claims were filed during the study period, of which n = 224 (26.4%) received compensation. The rate of claims was 0.15%, and the rate of compensation was 0.04% in relation to the total volume of births during the period. Substandard care was the most common (97.3%) criterion for compensation. There was a curvilinear increase in the claims rate and a linear increase in compensation rates from 2013 to 2019. More claims were filed and compensated for cesarean and vacuum-assisted deliveries than for unassisted vaginal deliveries. Delayed delivery (18.7%) and surgical technique failure (10.9%) were the most reported causes of injuries. Retained surgical bodies were the induced cause of injury with the highest rate of compensated claims (86.7%). The most common maternal injury was infection (17.9%) and pain (11.7%). Among neonatal injuries, severe (19.2%) and mild asphyxia (16.6%) were the most frequent. Burn injuries (93.3%) and fetal or neonatal death (60.5%) had the highest rate of compensated claims.

CONCLUSIONS

The study provided new information on substandard care and injuries in obstetric care in Finland. An increasing trend in claims and compensation rates was found. Identifying contributors to substandard care that lead to fetal asphyxia is important for improving obstetric safety. Further analysis of the association of claims and compensation rates with operative deliveries is needed to determine their causality. Frequent review of obstetric claims would be useful in providing more recent data on substandard care and preventable injuries.

The improvement and retention of skills in shoulder dystocia management with the use of high-fidelity simulation: The SAFE (SimulAtion high-FidElity) study

BACKGROUND

Shoulder dystocia is a relatively uncommon but serious childbirth-related emergency.

AIM

To explore the improvement and retention of skills in shoulder dystocia management through high-fidelity simulation training.

METHODS

The SAFE (SimulAtion high-FidElity) study was a prospective cohort study that utilised a high-fidelity birth simulator. Registered midwives and final year midwifery students were invited to participate in a one-day workshop at 6-monthly intervals. There was a 30-minute initial assessment, a 30-minute theoretical and hands-on training, and a 30-minute post-training assessment on shoulder dystocia management. Pre-training and post-training values for the predetermined outcomes were compared. In each workshop we assessed the proportion of successful simulated births, the performance of manoeuvres to manage shoulder dystocia, the head-to-body birth time, the fetal head traction force, the quality of communication, the perception of time-to-birth, and the self-reported confidence levels.

FINDINGS

The baseline workshop recruited 101 participants that demonstrated a significant increase in the proportion of successful simulated births (8.9% vs 93.1%), and a two-fold to three-fold increase in the score of manoeuvres, communication, and confidence after training. Those with low pre-training levels of competency and confidence improved the most post-training at baseline. There was a retention of manoeuvres, communication skills and confidence at 6 months. There was no reduction in fetal head traction force over time. Those being proficient before initial training retained and performed best at the 6-month follow-up.

CONCLUSION

The SAFE study found a significant improvement in skills and confidence after the initial high-fidelity simulation training that were retained after 6 months.

Causes for Medical Errors in Obstetrics and Gynaecology

Background: Quality strategies, interventions, and frameworks have been developed to facilitate a better understanding of healthcare systems. Reporting adverse events is one of these strategies. Gynaecology and obstetrics are one of the specialties with many adverse events. To understand the main causes of medical errors in gynaecology and obstetrics and how they could be prevented, we conducted this systematic review. Methods: This systematic review was performed in compliance with the Prisma 2020 guidelines. We searched several databases for relevant studies (Jan 2010-May 2023). Studies were included if they indicated the presence of any potential risk factor at the hospital level for medical errors or adverse events in gynaecology or obstetrics. Results: We included 26 articles in the quantitative analysis of this review. Most of these (n = 12) are cross-sectional studies; eight are case-control studies, and six are cohort studies. One of the most frequently reported contributing factors is delay in healthcare. In addition, the availability of products and trained staff, team training, and communication are often reported to contribute to near-misses/maternal deaths. Conclusions: All risk factors that were found in our review imply several categories of contributing factors regarding: (1) delay of care, (2) coordination and management of care, and (3) scarcity of supply, personnel, and knowledge.

Healthcare providers' perceptions and expectations of video-assisted debriefing of real-life obstetrical emergencies: a qualitative study from Denmark

OBJECTIVES

Video-assisted debriefing (VAD) of real-life obstetrical emergencies provides an opportunity to improve quality of care, but is rarely used in clinical practice. A barrier for implementation is the expected mental reservations among healthcare providers. The aim of this study was to explore healthcare providers' perceptions and expectations of VAD of real-life events.

SETTING

Participants were recruited from two Labour and Delivery Units in Denmark. In both units, VAD of real-life obstetrical emergencies had never been conducted.

PARTICIPANTS

22 healthcare providers (10 physicians, 9 midwives and 3 nursing assistants). During the study period (August-October 2021), semi-structured, individual interviews were conducted. Interviews were analysed using thematic analysis.

PRIMARY AND SECONDARY OUTCOME MEASURES

A qualitative description of healthcare providers' perceptions and expectations of VAD of real-life events.

RESULTS

Three major themes were identified: (1) Video-assisted debriefing (VAD) as an opportunity for learning: All participants expected VAD to provide an opportunity for learning and improving patient care. All participants expected the video to provide a 'bigger picture', by showing 'what was actually done' instead of 'what we believed was done'. (2) Video-assisted debriefing (VAD) as a cause for concern: The primary concern for all participants was the risk of being exposed as less competent. Participants were concerned that being confronted with every minor detail of their clinical practice would enhance their self-criticalness. (3) Preconditions for video-assisted debriefing (VAD): Participants emphasised the importance of organisational support from management. In addition, creating a safe environment for VAD, for example, by using only expert debriefers was considered an essential precondition for successful implementation.

CONCLUSIONS

The risk of being exposed as less competent was a barrier towards VAD of real-life events. However, the majority found the educational benefits to outweigh the risk of being exposed.

Evaluating the quality of care for postpartum hemorrhage with a new quantitative tool: a population-based study

To develop a new tool to assess the global quality of care for post-partum hemorrhage (PPH)-the leading preventable cause of maternal mortality worldwide-and to identify characteristics of maternity units associated with inadequate PPH management. This is a secondary analysis of the EPIMOMS population-based study conducted in 2012-2013 in 119 french maternity units (182,309 women who gave birth). We included women with severe PPH. We first developed a score to quantify the quality of care for PPH. Then, we identified characteristics of the maternity units associated with "inadequate care" defined by a score below the 25th percentile, with multi-level logistic regression adjusted for individual characteristics. The score combined 8 key components of care and took into account delivery mode and PPH cause. For PPH after vaginal delivery, the risk of inadequate care was increased in low versus high-volume maternity units (< 1000 deliveries/year: aOR-2.20 [1.12-4.32], [1000-2000 [deliveries/year: aOR-1.90 [1.02-3.56] compared to ≥ 3500 deliveries/year), in private versus public units (aOR-1.72 [1.00-2.97]), and in low versus high-level of care units (aOR-2.04 [1.24-3.35]). For PPH after cesarean, the only characteristic associated with an increased risk of inadequate care was the absence of 24/24-onsite anesthesiologist (aOR-4.34 [1.41-13.31]). These results indicate where opportunities for improvement are the greatest.

ABSTRACT Objectives: to develop a booklet as an educational technology, together with health professionals, patients and companions, aiming at their involvement in patient safety in maternity hospitals. Methods: a qualitative convergent care study, carried out in three stages at a maternity hospital in Belo Horizonte. The booklet construction took place between February and April 2021, with 13 professionals, 06 companions and 11 patients. Results: data content analysis was performed, creating three categories: Knowledge and experiences about patient and newborn safety in maternity hospitals; Challenges for involving patient and companion in safety actions; Assessment of patients, companions and professionals on the booklet construction process. The booklet construction involved the participation of health professionals, users and companions in all stages of the process. Final considerations: the participatory process enabled the creation of educational technology for the involvement of patients and companions in patient safety actions.

The effects of obstetric emergency team training on patient outcome: A systematic review and meta-analysis

INTRODUCTION

Little is known about the optimal simulation-based team training in obstetric emergencies. We aimed to review how simulation-based team training affects patient outcomes in obstetric emergencies.

MATERIAL AND METHODS

Search Strategy: MEDLINE, Embase, Cochrane Library, and Cochrane Central Register of Controlled Trials were searched up to and including May 15, 2021.

SELECTION CRITERIA

randomized controlled trials (RCTs) and cohort studies on obstetric teams in high-resource settings comparing the effect of simulation-based obstetric emergency team training with no training on the risk of Apgar scores less than 7 at 5 min, neonatal hypoxic ischemic encephalopathy, severe postpartum hemorrhage, blood transfusion of four or more units, and delay of emergency cesarean section by more than 30 min.

DATA COLLECTION AND ANALYSIS

The included studies were assessed using PRISMA, EPCO, and GRADE.

RESULTS

We found 21 studies, four RCTs and 17 cohort studies, evaluating patient outcomes after obstetric team training compared with no training. Annual obstetric emergency team training may reduce brachial plexus injury (six cohort studies: odds ratio [OR] 0.47, 95% CI 0.33-0.68; one RCT: OR 1.30, 95 CI% 0.39-4.33, low certainty evidence) and suggest a positive effect; but it was not significant on Apgar score below 7 at 5 min (three cohort studies: OR 0.77, 95% CI 0.51-1.19; two RCT: OR 0.87, 95% CI 0.72-1.05, moderate certainty evidence). The effect was unclear for hypoxic ischemic encephalopathy, umbilical prolapse, decision to birth interval in emergency cesarean section, and for severe postpartum hemorrhage. Studies with in situ multi-professional simulation-based training demonstrated the best effect.

CONCLUSIONS

Emerging evidence suggests an effect of obstetric team training on obstetric outcomes, but conflicting results call for controlled trials targeted to identify the optimal methodology for effective team training.

Adverse events reporting by obstetric units in Norway as part of their quality assurance and patient safety work: an analysis of practice

BACKGROUND

The Norwegian Board of Health Supervision aims to contribute to the improvement of quality and patient safety in the healthcare services. Planned audits were performed to investigate how 12 selected Norwegian obstetric units reported and analyzed adverse events as the part of their quality assurance and patient safety work.

METHODS

Serious adverse events coded as birth asphyxia, shoulder dystocia and severe postpartum hemorrhage that occurred during 2014 (the most recent year for which the quality assured data were available) were obtained from the Medical Birth Registry of Norway. The obstetric units were asked to submit medical records, internal adverse events reports, and their internal guidelines outlining which events should be reported to the quality assurance system. We identified the adverse events at each obstetric unit that were reported internally and/or to the central authorities. Two obstetricians carried out an evaluation of each event reported.

RESULTS

Five hundred fifty-three serious adverse events were registered among 17,323 births that took place at the selected units. Twenty-one events were excluded because of incorrect coding or missing information. Eight events were registered in more than one category, and these were distributed to the category directly related to injury or adverse outcome. Nine of twelve (75 %) obstetric units had written guidelines describing which events should be reported. The obstetric units reported 49 of 524 (9.3 %) serious adverse events in their internal quality assurance system and 39 (7.4 %) to central authorities. Of the very serious adverse events, 29 of 149 (19.4 %) were reported. Twenty-three of 49 (47 %) reports did not contain relevant assessments or proposals for improving quality and patient safety.

CONCLUSIONS

This study showed that adverse event reporting and analyses by Norwegian obstetric units, as a part of quality assurance and patient safety work, are suboptimal. The reporting culture and compliance with guidelines need to be improved substantially for better safety in patient care, risk mitigation and clinical quality assurance.

Perinatal asphyxia from the obstetric standpoint

Perinatal asphyxia remains one of the major causes of morbidity and mortality for term newborns. Though access to health care and birth attendants have decreased the rate, Neonatal encephalopathy (NE) has not been eliminated. Worldwide, women at socioeconomic disadvantage have the highest risk of delivering a neonate with NE. Neonates that will experience perinatal asphyxia cannot be easily identified prospectively and the intrapartum testing available is not specific enough to clearly indicate the best course of action in most cases. Despite this, training programs that aim to decrease morbidity and mortality from all causes appear to be associated with fewer cases of perinatal asphyxia. The current best approach is to support education and communication for all people involved in the care of birthing women. Ideally, new technology will address identification of the fetus likely to be affected or the fetus who is beginning to experience injury in advance of delivery.

How common is substandard obstetric care in adverse events of birth asphyxia, shoulder dystocia and postpartum hemorrhage? Findings from an external inspection of Norwegian maternity units

INTRODUCTION

The Norwegian Board of Health Supervision inspects healthcare institutions to ensure safety and quality of health and welfare services. A planned inspection of 12 maternity units aimed to investigate the practice of obstetric care in the case of birth asphyxia, shoulder dystocia and severe postpartum hemorrhage.

MATERIAL AND METHODS

The inspection was carried out at two large, four medium and six small maternity units in Norway in 2016 to investigate adverse events that occurred between 1 January and 31 December 2014. Six of them were selected as control units. The Norwegian Board of Health Supervision searched the Medical Birth Registry of Norway to identify adverse events in each of the categories and then requested access to the medical records for all patients identified. Information about guidelines, formal teaching and simulation training at each unit was obtained by sending a questionnaire to the obstetrician in charge of each maternity unit.

RESULTS

The obstetric units inspected had 553 serious adverse events of birth asphyxia, shoulder dystocia or severe postpartum hemorrhage among 17 323 deliveries. Twenty-nine events were excluded from further analysis due to erroneous coding or missing data in the patients' medical records. We included 524 cases (3.0% of all deliveries) of adverse events in the final analysis. Medical errors caused by substandard care were present in 295 (56.2%) cases. There was no difference in the prevalence of substandard care among the maternity units according to their size. Surprisingly, we found significantly fewer cases with substandard care in the units which the supervisory authorities considered particularly risky before the inspection, compared with the control units. Seven of the 12 units had regular formal teaching and training arrangements for obstetric healthcare personnel as outlined in the national guidelines.

CONCLUSIONS

Prevalence of adverse events was 3% and similar in all maternity units irrespective of their size. A breach in the standard of care was observed in 56.2% of cases and almost half of the maternity units did not follow national recommendations regarding teaching and practical training of obstetric personnel, suggesting that they should focus on implementing guidelines and training their staff.
