Enhanced recovery after caesarean delivery versus standard care studies: a systematic review of interventions and outcomes

Development and validation of a Spanish version of the Obstetric Quality of Recovery-10 item score (ObsQoR-10-Spanish)

Background

Spanish is the second most spoken language globally with around 475 million native speakers. We aimed to validate a Spanish version of the Obstetric Quality of Recovery-10 item (ObsQoR-10) patient-reported outcome measure.

Methods

ObsQoR-10-Spanish was developed using EuroQoL methodology. ObsQoR-10-Spanish was assessed in 100 Spanish-speaking patients undergoing elective Caesarean or vaginal delivery. Patients <38 weeks, undergoing an intrapartum Caesarean delivery, intrauterine death, or maternal admission to the intensive care unit (ICU) were excluded. Validity was assessed by evaluating (i) convergent validity-correlation with 24-h EuroQoL and global health visual analogue scale (GHVAS) scores (0-100); (ii) discriminant validity-difference in ObsQoR-10-Spanish score for patients with GHVAS scores >70 vs <70; (iii) hypothesis testing-correlation of ObsQoR score with maternal and neonatal factors; and (iv) cross-cultural validity assessed using differential item functioning analysis. Reliability was assessed by evaluating: (i) internal consistency; (ii) split-half reliability and (iii) test-retest reliability; and (iv) floor and ceiling effects.

Results

One hundred patients were approached, recruited, and completed surveys. Validity: (i) convergent validity: the ObsQoR 24-h score correlated moderately with the 24-h EuroQoL (r=-0.632) and GHVAS scores (r=0.590); (ii) discriminant validity: the ObsQoR-10-Spanish 24-h scores were higher in women who delivered vaginally compared to via Caesarean delivery, (mean [standard deviation] scores were 89 [9] vs 81 [12]; P<0.001). The 24-h ObsQoR-Spanish scores were lower in patients experiencing a poor vs a good recovery (mean [standard deviation] scores were 76 [12.3] vs 87.1 [10.6]; P=0.001); (iii) hypothesis testing: the ObsQoR-10 score correlated negatively with age (r=-0.207) and positively with 5-min (r=0.204) and 10-min (r=0.243) Apgar scores. Remaining correlations were not significant; and (iv) differential item functioning analysis suggested no potential bias among the 10 items. Reliability: (i) internal consistency was good (Cronbach alpha=0.763); (ii) split-half reliability was good (Spearman-Brown prophesy reliability estimate of 0.866); (iii) test-retest reliability was excellent with an intra-class correlation coefficient of 0.90; and (iv) floor and ceiling effects: six patients scored a maximum total ObsQoR-10 score.

Conclusions

The ObsQoR-10-Spanish patient-reported outcome measure is valid, reliable, and clinically feasible, and should be considered for use in Spanish-speaking women to assess quality of inpatient postpartum recovery.

A narrative review of the literature relevant to obstetric anesthesiologists: the 2023 Gerard W. Ostheimer lecture

This narrative review of the 2023 Gerard W. Ostheimer lecture presented at the Society for Obstetric Anesthesia and Perinatology 2023 annual meeting summarizes 2022 literature relevant to obstetric anesthesiologists.

ANTENATAL STUDIES

Neonatal morbidity is reduced with antenatal maternal buprenorphine compared with methadone for treatment of opioid use disorder. Antenatal pregnancy allergy testing is safe and feasible.

ANALGESIA AND ANESTHESIA STUDIES

Intrathecal (IT) 3% chloroprocaine for cervical cerclage results in faster sensory block resolution and discharge readiness compared with bupivacaine. The ED90 of 3% chloroprocaine (with IT fentanyl 10 µg) is 49.5 mg. Dural puncture epidural technique does not improve the quality of labor analgesia in obese parturients compared with epidural analgesia. Low- (>0.08 to ≤0.1%) and ultra-low (<0.08%) concentrations of bupivacaine for epidural analgesia maintenance result in similar maternal and neonatal outcomes. Lower doses of first line uterotonic agents are non-inferior to higher doses (oxytocin 0.5 IU vs. 5 IU and carbetocin 20 vs. 100 µg) in patients at low risk for postpartum hemorrhage. Supplemental analgesia or conversion to general anesthesia is necessary in approximately 15% of elective cesarean deliveries. Intravenous dexamethasone improves analgesia outcomes, however optimal dosing and timing remain unclear; it may induce neonatal hypoglycemia in the setting of gestational diabetes.

POSTPARTUM STUDIES

A core outcome set may help evaluate enhanced recovery protocol implementation. History of migraine and accidental dural puncture (ADP) above the L3 level are associated with epidural blood patch (EBP) failure and ADP at or below L3 and >48 h interval between ADP and EBP are associated with success.

Obstetric and medical factors rather than psychosocial characteristics explain why eligible women do not complete the enhanced recovery after elective caesarean (EREC) pathway: A prospective cohort study

BACKGROUND

An Australian health-service implemented an 'enhanced recovery after elective caesarean' pathway with next-day discharge.

PROBLEM

Previous anecdotal reports indicated that a large percentage of eligible women were not discharged the next day and therefore were not regarded as having completed the pathway. Psychosocial factors were expected to be the leading reason for prolonged hospitalisation.

AIM

The study objectives were to: enumerate the percentage of women assessed as eligible for EREC who subsequently did not complete the pathway and the reasons; and to describe women's antenatal satisfaction with preparation, preferences, and perceived support. Women who completed the pathway versus those who did not were compared on antenatal biopsychosocial characteristics.

METHODS

This exploratory prospective cohort study enrolled consenting eligible women from antenatal clinics and used patient records and questionnaire data. Comparative statistical techniques were used.

FINDINGS

62 % of women did not complete the pathway, with medical and obstetric factors being the most common reasons (80 %). There was statistically significant evidence of lower antenatal stress levels for those who completed EREC (median=5) relative to those who did not (median=8; P = 0.035); although these findings may not be of clinical importance. Antenatally, 51 % of women felt prepared for early discharge, 36 % needed more information, 19 % disliked hospital, 93 % agreed that family togetherness after birth was important. Most agreed that staff (76 %) and family (67 %) supported the pathway.

CONCLUSION

This study indicated that a large percentage of women assessed as eligible did not complete EREC and that obstetric and medical factors, rather than psychosocial characteristics, largely explained this. This provides reassurance to clinicians and women that discharge home is working as intended and is useful for planning similar models of care. Higher stress levels in the antenatal period were demonstrated for women who did not complete EREC suggesting the need for further research into how to support these women.

Use of the Obstetric Quality-of-Recovery score (ObsQoR-11) to measure the impact of an enhanced recovery programme for elective caesarean section

BACKGROUND

Enhanced recovery after caesarean (ERAC) has been shown to postoperatively reduce opioid consumption, reduce pain scores, and shorten hospital stay. Arguably, none of these measures provide for a patient-centred approach. We believe that patient-reported outcome measures (PROMs) represent a more holistic approach to the reporting of outcomes. One such PROM is the Obstetric Quality-of-Recovery Score (ObsQoR-11). This has been shown to be a valid and reliable assessment of recovery after elective caesarean section.

METHODS

This before-and-after quality improvement programme studied consecutive patients undergoing elective caesarean section. We implemented an ERAC pathway with the aim of improving quality of recovery and patient satisfaction. Our primary outcome was the change in the ObsQoR-11 score.

RESULTS

A total of 318 medical records were reviewed (n = 93 before ERAC, n = 225 after ERAC). There was a significant improvement in ObsQoR-11 score in ERAC patients compared with pre-ERAC patients (85.0 vs 82.3, P < 0.001). Morphine consumption (MMEQ) was reduced by 10% overall in the ERAC group, with no increase in pain scores at day 1 postoperatively and a decrease in pain scores on day 2 in the ERAC group (P = 0.02). The length of hospital stay was significantly shorter in ERAC patients (63.1 h vs 79.9 h, P < 0.001).

CONCLUSIONS

Our study demonstrated an improved ObsQoR-11 score after ERAC implementation. This is the first example in the literature of using ObsQoR-11 in ERAC. We believe this is a more comprehensive way to assess patient recovery and the impact of an ERAC programme.

Practice of enhanced recovery after cesarean delivery in resource-limited setting

Background

Caesarean section is one of the most common procedures and clinician faces dual challenges with feto-maternal morbidity and mortality after caesarean delivery. Enhanced recovery after caesarean delivery protocols might effectively reduce postoperative feto-maternal morbidity and mortality. Therefore, this study aimed to assess practice of enhanced recovery after caesarean delivery among parturients who underwent elective caesarean delivery.

Methods

A cross-sectional study design was conducted from March to June 2021 on 225 consecutive parturients scheduled for elective caesarean delivery. A semi-structured questionnaire which developed from Society of Obstetric Anesthesia and Perinatology, evidence-based recommendations regarding enhanced recovery after a caesarean (2020) to collect data. Data was collected through direct observation, reviewing the chart, and patient's interview. Data were entered and analyzed in SPSS version 20.

Result

Preoperative pathway; limit fasting interval (91%), haemoglobin screen and optimization (82%), and patient education (100%) found good Areas of practice Intraoperative pathway; administering postoperative nausea and vomiting prophylaxis (100%), fluid optimization (88%), neuraxial anaesthesia with a neuraxial opioid (91%), initiating multimodal analgesia (88%), optimal uterotonic administration (88%), delayed umbilical cord clamping (85%), and prophylactic antibiotic (100%) found areas with good areas of practice. Postoperative pathways; initiation of multimodal analgesia (74%) and early removal of the urinary catheter (62%) were found areas good areas of practice.

Conclusion and recommendation

The overall practice of enhanced recovery after caesarean delivery was below the target. The authors recommend that this comprehensive and specialized hospital administrator implement enhanced recovery after caesarean delivery protocol and give short-term training for health professionals' about the protocol.

United States rural residence is associated with increased acute maternal end-organ injury or mortality after birth: a retrospective multi-state analysis, 2007-2018

BACKGROUND

Geographic-based healthcare determinants and choice of anesthesia have been shown to be associated with maternal morbidity and mortality. We explored whether differences in maternal outcomes based on maternal residence, and anesthesia type for cesarean and vaginal birth, exist.

METHODS

This study was a retrospective multi-state analysis; patient residence was the predictor variable of interest and a composite binary measure of maternal end-organ injury or inpatient mortality was the primary outcome. Our secondary outcomes included a binary measure of anesthesia type for cesarean birth (general vs. neuraxial [NA]) and NA analgesia for vaginal birth (no NA vs. NA). Our predictor variable of interest was patient residency (reference category central metropolitan areas of >1 million population), fringe large metropolitan county, medium metropolitan, small metropolitan, micropolitan, and non-metropolitan or micropolitan county.

RESULTS

Women residing in micropolitan (OR 1.17; 95% CI 1.09 to 1.27) and non-metropolitan or micropolitan counties (OR 1.14; 95% CI 1.04 to 1.24) had the highest adjusted increased odds of adverse maternal outcomes. Those residing in suburban, medium, and small metropolitan areas underwent general anesthesia less often during cesarean births than those residing in urban areas. Patients residing in micropolitan rural (OR 2.07; 95% CI 2.02 to 2.12) and non-metropolitan or micropolitan (2.25; 95% CI 2.16 to 2.34) counties underwent vaginal births without NA analgesia more than twice as often as those residing in urban areas.

CONCLUSIONS

Rural-urban disparities in maternal end-organ damage and mortality exist and anesthesia choice may play an important role in these disparate outcomes.

Standardized Order Sets Do Not Eliminate Racial or Ethnic Inequities in Postpartum Pain Management

Objective

To quantify the extent to which a standardized pain management order set reduced racial and ethnic inequities in post-cesarean pain evaluation and management.

Methods

We conducted a retrospective cohort study to quantify racial and ethnic differences in pain evaluation and management before (July 2014-June 2016) and after implementation of a standardized post-cesarean order set (March 2017-February 2018). Electronic medical records were queried for pain scores >7/10, number of pain assessments, and opioid, nonsteroidal anti-inflammatory drug (NSAID), and acetaminophen doses. Outcomes were grouped into 0 to <24 and 24-48 h postpartum, and stratified by race/ethnicity (Hispanic, non-Hispanic Black [NHB], non-Hispanic White [NHW], Asian, and other), as documented in the electronic health record. Analyses included logistic regression for the categorical outcome of pain score >7 (severe pain), and linear regression, with propensity score adjustment. Main effect and interaction terms were used to calculate the difference-in-difference in pain process and outcome measures between the baseline and follow-up periods.

Results

After order set implementation (N=888), severe pain remained more common among NHB patients (% pain scores >7 NHW vs. NHB 0 to <24 h: 22% vs. 33%, p=0.003; 24-48 h: 26% vs. 40%, p<0.001). Among all patients, pain management processes changed after implementation of the order set, with overall fewer assessments, less Opioids, and more nonopioid analgesics. However, racial and ethnic inequities in a number of assessments and in treatment were unchanged (all p for interaction >0.05), with the exception of a modest increase in NSAID doses 24-48 h postpartum for Hispanic patients.

Conclusion

A standardized pain management order set reduced overall postpartum opioid use, but did not reduce racial and ethnic disparities in pain evaluation and management. Future work should investigate racial equity-focused education and interventions designed to eliminate disparities in pain management.

Postpartum recovery of nulliparous women following scheduled cesarean delivery and spontaneous vaginal delivery: a prospective observational study

BACKGROUND

Inpatient postpartum recovery trajectories following cesarean delivery and spontaneous vaginal delivery are underexplored.

OBJECTIVE

This study primarily aimed to compare recovery following cesarean delivery and spontaneous vaginal delivery in the first postpartum week, and secondarily to evaluate psychometrically the Japanese version of the Obstetric Quality of Recovery-10 scoring tool.

STUDY DESIGN

Following institutional review board approval, the EQ-5D-3L (EuroQoL 5-Dimension 3-Level) questionnaire and a Japanese version of the Obstetric Quality of Recovery-10 measure were used to evaluate inpatient postpartum recovery in uncomplicated nulliparous parturients delivering via scheduled cesarean delivery or spontaneous vaginal delivery.

RESULTS

A total of 48 and 50 women who delivered via cesarean delivery and spontaneous vaginal delivery, respectively, were recruited. Women delivering via scheduled cesarean delivery experienced significantly worse quality of recovery on days 1 and 2 compared with those who had spontaneous vaginal delivery. Quality of recovery significantly improved daily, plateauing at days 4 and 3 for cesarean delivery and spontaneous vaginal delivery groups, respectively. Compared with cesarean delivery, spontaneous vaginal delivery was associated with prolonged time to analgesia requirement, decreased opioid consumption, reduced antiemetic requirement, and reduced times to liquid/solid intake, ambulation, and discharge. Obstetric Quality of Recovery-10-Japanese is a valid (correlates with the EQ-5D-3L including a global health visual analog scale, gestational age, blood loss, opioid consumption, time until first analgesic request, liquid/solid intake, ambulation, catheter removal, and discharge), reliable (Cronbach alpha=0.88; Spearman-Brown reliability estimate=0.94; and intraclass correlation coefficient=0.89), and clinically feasible (98% 24-hour response rate) measure.

CONCLUSION

Inpatient postpartum recovery is significantly better in the first 2 postpartum days following spontaneous vaginal delivery compared with scheduled cesarean delivery. Inpatient recovery is largely achieved within 4 and 3 days following scheduled cesarean delivery and spontaneous vaginal delivery, respectively. Obstetric Quality of Recovery-10-Japanese is a valid, reliable, and feasible measure of inpatient postpartum recovery.

Measuring enhanced recovery in obstetrics: a narrative review

Enhanced recovery after cesarean delivery is a protocolized approach to perioperative care, with the aim to optimize maternal recovery after surgery. It is associated with improved maternal and neonatal outcomes, including decreased length of hospital stay, opioid consumption, pain scores, complications, increased maternal satisfaction, and increased breastfeeding success. However, the pace and enthusiasm of adoption of enhanced recovery after cesarean delivery internationally has not yet been matched with high-quality evidence demonstrating its benefit, and current studies provide low- to very low-quality evidence in support of enhanced recovery after cesarean delivery. This article provides a summary of current measures of enhanced recovery after cesarean delivery success, and optimal measures of inpatient and outpatient postpartum recovery. We summarize outcomes from 22 published enhanced recovery after cesarean delivery implementation studies and 2 meta-analyses. A variety of disparate metrics have been used to measure enhanced recovery after cesarean delivery success, including process measures (length of hospital stay, bundle compliance, preoperative fasting time, time to first mobilization, time to urinary catheter removal), maternal outcomes (patient-reported outcome measures, complications, opioid consumption, satisfaction), neonatal outcomes (breastfeeding success, Apgar scores, maternal-neonatal bonding), cost savings, and complication rates (maternal readmission rate, urinary recatheterization rate, neonatal readmission rate). A core outcome set for use in enhanced recovery after cesarean delivery studies has been developed through Delphi consensus, involving stakeholders including obstetricians, anesthesiologists, patients, and a midwife. Fifteen measures covering key aspects of enhanced recovery after cesarean delivery adoption are recommended for use in future enhanced recovery after cesarean delivery implementation studies. The use of these outcome measures could improve the quality of evidence surrounding enhanced recovery after cesarean delivery. Using evidence-based evaluation guidelines developed by the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) group, the Obstetric Quality of Recovery score (ObsQoR) was identified as the best patient-reported outcome measure for inpatient postpartum recovery. Advances in our understanding of postpartum recovery as a multidimensional and dynamic construct have opened new avenues for the identification of optimum patient-reported outcome measures in this context. The use of standardized measures such as these will facilitate pooling of data in future studies and improve overall levels of evidence surrounding enhanced recovery after cesarean delivery. Larger studies with optimal study designs, using recommended outcomes including patient-reported outcome measures, will reduce variation and improve data quality to help guide future recommendations.

Practice-changing evidence is presented and evaluated. A priority list for clinical updates, systems, and quality improvement initiatives is presented.

Cesarean delivery using an ERAS-CD process for nonopioid anesthesia and analgesia drug/medication management

Cesarean delivery (CD) is a surgical delivery of a neonate with surgical access through the maternal abdominal and uterine structures. The Enhanced Recovery After Surgery (ERAS) protocol is a standardized perioperative care program and surgery quality improvement process that has had global spread across numerous surgical disciplines. The medical and surgical use of opioids for pain management and the nonmedical opioid use, over the last three decades, have significantly increased the prevalence of abuse and addiction to opioids. This review summarizes pain, pregnancy substance use, and ERAS-directed analgesia and anesthesia for opioid use reduction or elimination in the operative and postoperative periods. Enhanced recovery (quality and safety) in the surgical CD context requires collaboration, consensus, and appropriate clinical prioritization to allow for the identification of 'the right patient, in the right clinical situation, with the right informed consent, and the right clinical care team and health system'.

Practice towards perioperative care of cesarean delivery in Debre Tabor Comprehensive Specialized Hospital, North Central Ethiopia: Cross-sectional study

Background

Perioperative obstetric care is vital in clinical practice to improve maternal and neonatal outcomes. The standardized practice of perioperative obstetrics care service has a great role in the reduction of both expected and unexpected adverse outcomes. So, the purpose of this study was to assess the implementation of perioperative obstetric care services based on standards of Enhanced Recovery after Cesarean Delivery and the Society of Anesthesiology and Perinatology.

Method and materials

A cross-sectional study was conducted on 161 mothers with an elective cesarean delivery from August 10, 2021, to May 15, 2022. The standard of this study was taken from evidence-based practice guidelines of perioperative practice for an elective cesarean delivery. Informed consent was taken from all study participants. The data was collected through direct observation using a standard checklist changed to standardized question forms with two checking components (“Yes”, and “No”), and data were entered into SPSS version 20 for analysis and interpretation. Descriptive analysis was done and the results were expressed in numbers and percentages using a table.

Results

A total of 161 elective cesarean sections were involved to identify the level of perioperative care. Administration of first-generation antibiotics prophylaxis, aqueous povidone-iodine solution-based skin preparations, and preparation for immediate neonatal resuscitation were fully performed based on the standards.

Conclusions

The majority of elective caesarian deliveries were carried out below the recommended level as per the checklists for perioperative practice. So, added interventions are needed to improve perioperative obstetrics care services on those standards which are not totally applied and partially performed.

•

The overall practice of perioperative obstetrics care was poor.

•

Added intervention is needed for those standards performed bellow standards.

•

Practice guidelines and standards are required in practice area.

Expert Consensus Regarding Core Outcomes for Enhanced Recovery after Cesarean Delivery Studies: A Delphi study

BACKGROUND

Heterogeneity among reported outcomes from enhanced recovery after cesarean delivery impact studies is high. This study aimed to develop a standardized enhanced recovery core outcome set for use in future enhanced recovery after cesarean delivery studies.

METHODS

An international consensus study involving physicians, patients and a director of Midwifery and Nursing Services, was conducted using a three-round modified Delphi approach (2 rounds of electronic questionnaires and a 3rd round e-discussion), to produce the core outcome set. An initial list of outcomes was based on a previously published systematic review. Consensus was obtained for the final core outcome set, including definitions for key terms, and preferred units of measurement. Strong consensus was defined as ≥70% agreement and weak consensus as 50-69% agreement. Of the 64 stakeholders who were approached, 32 agreed to participate. All 32, 31 and 26 stakeholders completed Rounds 1, 2 and 3, respectively.

RESULTS

The number of outcomes in the final core outcome set was reduced from 98 to 15. Strong consensus (≥70% stakeholder agreement) was achieved for 15 outcomes. The core outcome set included: length of hospital stay; compliance with enhanced recovery protocol; maternal morbidity (hospital re-admissions or unplanned consultations); provision of optimal analgesia (maternal satisfaction, compliance with analgesia, opioid consumption / requirement and incidence of nausea or vomiting); fasting times; breastfeeding success; and times to mobilization and urinary catheter removal. The Obstetric Quality of Recovery-10 item composite measure was also included in the final core outcome set. Areas identified as requiring further research included readiness for discharge and analysis of cost savings.

CONCLUSIONS

Results from an international consensus to develop a core outcome set for enhanced recovery after cesarean delivery are presented. These are outcomes that could be considered when designing future enhanced recovery studies.

Enhanced Recovery after Surgery: Cesarean Delivery

This review summarizes the importance of enhanced recovery after surgery (ERAS) implementation for cesarean deliveries (CDs) and explores ERAS elements shared with the non-obstetric surgical population. The Society for Obstetric Anesthesia and Perinatology (SOAP) consensus statement on ERAS for CD is used as a template for the discussion. Suggested areas for research to improve our understanding of ERAS in the obstetric population are delineated. Strategies and examples of anesthesia-specific protocol elements are included.

Maternal and fetal hypothermia: more preventive compliance is required for a mother and her fetus while undergoing cesarean delivery; a quality improvement review

OBJECTIVE

Cesarean delivery is common, involves two patients, has numerous multi-disciplinary health care providers involved in the delivery management, but has variable levels of anesthesia and health services implementation for decreasing maternal hypothermia and the maternal and neonatal morbidity (and mortality). Limited implementation for either of the ERAS-CD or the ERAC guidelines, for inadvertent or preventive maternal hypothermia, is likely to be occurring on labor delivery floors. This Quality Improvement (QI) review focuses on cesarean delivery and maternal hypothermia.

METHODS

This quality and safety initiative used SQUIRE 2.0 methodology and concurrent PubMed searches to identify systematic review, meta-analysis, topic directed studies, additional published cohorts in the topic area not included in SR/MA, limited case reports that had specific clinical outcomes related to maternal hypothermia and fetal effects.

RESULTS

Two quality and safety improvement guidelines have defined the hypothermia activity element differently, with ERAS-CD recommending to prevent hypothermia, while ERAC recommending to maintain normothermia. The peer-reviewed literature indicates that the knowledge associated with surgical hypothermia outcome is known but it is not implemented for maternal cesarean delivery care. Increased maternal-effect recognition, surveillance, triage, and evidenced-based protocol management is required for the maternal - neonatal dyad undergoing cesarean delivery for the clinical reduction/prevention of neonatal hypothermia that has proven evidence-based maternal morbidity and neonatal morbidity/mortality.

CONCLUSION

TEAM-based anesthesia, obstetrical, neonatology-pediatrics and nursing research collaboration is required through quality-safety-ERAS-ERAC directed processes. Healthcare system recognition and financial support is required for maternal-fetal-neonatal hypothermia prevention protocols implementation.

Impact of enhanced recovery after cesarean delivery on maternal outcomes: A systematic review and meta-analysis

BACKGROUND

This meta-analysis explores the impact of enhanced recovery after cesarean delivery (ERAC) on maternal outcomes.

METHODS

We searched 4 databases (Web of Science, Embase, PubMed and CINAHL) in October 2020 without date limiters, for studies quantitatively comparing ERAC implementation to a control group. The primary outcome was length of hospital stay and secondary outcomes included time to mobilization and time to urinary catheter removal, opioid consumption, readmission rates and cost savings. Mean differences and odds ratios (MD and OR with 95% confidence intervals) were calculated. Levels of evidence were assessed using GRADE.

RESULTS

Twelve studies involving 17,607 patients (9693 without ERAC and 7914 with ERAC) were included. ERAC was associated with reduced: length of hospital stay (MD -0.51 days [-0.94, -0.09]; p = 0.018; I2 = 99%), time to first mobilization (MD -11.05 h [-18.64, -3.46]; p = 0.004; I2 = 98%), time to urinary catheter removal (MD -13.19 h [-17.59, -8.79]; p < 0.001; I2 = 97%) and opioid consumption (MD -21.85 mg morphine equivalents [-33.19, -10.50]; p = < 0.001; I2 = 91%), with no difference in maternal readmission rate (OR 1.23 [0.96, 1.57]; p = 0.10; I2 = 0%). Three studies reported cost savings associated with ERAC. The GRADE levels of evidence were rated as low or very low quality for all study outcomes.

CONCLUSION

ERAC is associated with reduction in length of stay, times to first mobilization and urinary catheter removal and opioid consumption. ERAC does not significantly affect maternal hospital readmission rates following discharge. Further studies are required to determine which ERAC interventions to implement and which outcomes best determine ERAC efficacy.

The Clinical Efficacy and Safety of Enhanced Recovery After Surgery for Cesarean Section: A Systematic Review and Meta-Analysis of Randomized Controlled Trials and Observational Studies

Background: Enhanced recovery after surgery (ERAS) has been adopted in some maternity units and studied extensively in cesarean section (CS) in the last years, showing encouraging results in clinic practice. However, the present evidence assessing the effectiveness of ERAS for CS remains weak, and there is a paucity in the published literature, especially in improving maternal outcomes. Our study aimed to systematically evaluate the clinical efficacy and safety of ERAS protocols for CS.

Methods: A systematic literature search using Embase, PubMed, and the Cochrane Library was carried out up to October 2020. The appropriate randomized controlled trials (RCTs) and observational studies applying ERAS for patients undergoing CS were included in this study, comparing the effect of ERAS protocols with conventional care on length of hospital stay (LOS), readmission rate, incidence of postoperative complications, postoperative pain score, postoperative opioid use, and cost of hospitalization. All statistical analyses were conducted with the RevMan 5.3 software.

Results: Ten studies (four RCTs and six observational studies) involving 16,391 patients were included. ERAS was associated with a decreased LOS (WMD −7.47 h, 95% CI: −8.36 to −6.59 h, p < 0.00001) and lower incidence of postoperative complications (RR: 0.50, 95% CI: 0.37 to 0.68, p < 0.00001). Moreover, pooled analysis showed that postoperative pain score (WMD: −1.23, 95% CI: −1.32 to −1.15, p < 0.00001), opioid use (SMD: −0.46, 95% CI: −0.58 to −0.34, p < 0.00001), and hospital cost (SMD:−0.54, 95% CI: −0.63 to −0.45, p < 0.00001) were significantly lower in the ERAS group than in the conventional care group. No significant difference was observed with regard to readmission rate (RR: 0.86, 95% CI: 0.48 to 1.54, p = 0.62).

Conclusions: The available evidence suggested that ERAS applying to CS significantly reduced postoperative complications, lowered the postoperative pain score and opioid use, shortened the hospital stay, and potentially reduced hospital cost without compromising readmission rates. Therefore, protocols implementing ERAS in CS appear to be effective and safe. However, the results should be interpreted with caution owing to the limited number and methodological quality of included studies; hence, future large, well-designed, and better methodological quality studies are needed to enhance the body of evidence.

A systematic review of patient-reported outcome measures to assess postpartum pain using Consensus Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines

BACKGROUND

We performed a systematic review using Consensus Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines to identify the best available patient-reported outcome measure (PROM) of postpartum pain.

METHODS

This review follows COSMIN guidelines. We searched four databases with no date limiters, for previously identified validated PROMs used to assess postpartum pain. PROMs evaluating more than one author-defined domain of postpartum pain were assessed. We sought studies evaluating psychometric properties. An overall rating was then assigned based upon COSMIN analysis, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the level of evidence for psychometric properties of included PROMs. These assessments were used to make recommendations and identify the best PROM to assess postpartum pain.

RESULTS

We identified 19 studies using seven PROMs (involving 3511 women), which evaluated postpartum pain. All included studies evaluated ≥1 psychometric property of the included PROMs. An adequate number of pain domains was assessed by the Brief Pain Inventory (BPI), Short Form-BPI (SF-BPI), and McGill Pain Questionnaire (MPQ). The SF-BPI was the only PROM to demonstrate adequate content validity and at least a low-level of evidence for sufficient internal consistency, resulting in a Class A recommendation (the best performing instrument, recommended for use).

CONCLUSION

SF-BPI is the best currently available PROM to assess postpartum pain. However, it fails to assess several important domains and only just met the criteria for a Class A recommendation. Future studies are warranted to develop, evaluate, and implement a new PROM designed to specifically assess postpartum pain.

Society for Obstetric Anesthesia and Perinatology: Consensus Statement and Recommendations for Enhanced Recovery After Cesarean

The purpose of this article is to provide a summary of the Enhanced Recovery After Cesarean delivery (ERAC) protocol written by a Society for Obstetric Anesthesia and Perinatology (SOAP) committee and approved by the SOAP Board of Directors in May 2019. The goal of the consensus statement is to provide both practical and where available, evidence-based recommendations regarding ERAC. These recommendations focus on optimizing maternal recovery, maternal-infant bonding, and perioperative outcomes after cesarean delivery. They also incorporate management strategies for this patient cohort, including recommendations from existing guidelines issued by professional organizations such as the American College of Obstetricians and Gynecologists and the American Society of Anesthesiologists. This consensus statement focuses on anesthesia-related and perioperative components of an enhanced recovery pathway for cesarean delivery and provides the level of evidence for each recommendation.

Use of Patient-Reported Outcome Measures to Assess Outpatient Postpartum Recovery: A Systematic Review

IMPORTANCE

Outpatient postpartum recovery is an underexplored area of obstetrics. There is currently no consensus regarding which patient-reported outcome measure (PROM) clinicians and researchers should use to evaluate postpartum recovery.

OBJECTIVE

To evaluate PROMs of outpatient postpartum recovery using Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines.

EVIDENCE REVIEW

An initial literature search performed in July 2019 identified postpartum recovery PROMs and validation studies. A secondary search in July 2020 identified additional validation studies. Both searches were performed using 4 databases (Web of Science, Embase, PubMed, and CINAHL), with no date limiters. Studies with PROMs evaluating more than 3 proposed outpatient postpartum recovery domains were considered. Studies were included if they assessed any psychometric measurement property of the included PROMs in the outpatient postpartum setting. The PROMs were assessed for the following 8 psychometric measurement properties, as defined by COSMIN: content validity, structural validity, internal consistency, cross-cultural validity and measurement invariance, reliability, measurement error, hypothesis testing, and responsiveness. Psychometric measurement properties were evaluated in each included study using the COSMIN criteria by assessing (1) the quality of the methods (very good, adequate, doubtful, inadequate, or not assessed); (2) overall rating of results (sufficient, insufficient, inconsistent, or indeterminate); (3) level of evidence assessed using the Grading of Recommendations, Assessment, Development and Evaluations assessment tool; and (4) level of recommendation, which included class A (recommended for use; showed adequate content validity with at least low-quality evidence for sufficient internal consistency), class B (not class A or class C), or class C (not recommended).

FINDINGS

In total, 15 PROMs (7 obstetric specific and 8 non-obstetric specific) were identified, evaluating outpatient postpartum recovery in 46 studies involving 19 165 women. The majority of psychometric measurement properties of the included PROMs were graded as having very-low-level or low-level evidence. The best-performing PROMs that received class A recommendations were the Maternal Concerns Questionnaire, the Postpartum Quality of Life tool, and the World Health Organization Quality of Life-BREF. The remainder of the evaluated PROMs had insufficient evidence to make recommendations regarding their use (and received class B recommendations).

CONCLUSIONS AND RELEVANCE

This review found that the best-performing PROMs currently available to evaluate outpatient postpartum recovery were the Maternal Concerns Questionnaire, the Postpartum Quality of Life tool, and the World Health Organization Quality of Life-BREF; however, these tools all had significant limitations. This study highlights the need to focus future efforts on robustly developing and validating a new PROM that may comprehensively evaluate outpatient postpartum recovery.

Postpartum recovery: what does it take to get back to a baseline?

PURPOSE OF REVIEW

Limited guidance exists regarding how to assess postpartum recovery. In this article, we discuss various aspects of inpatient and outpatient postpartum recovery.

RECENT FINDINGS

The postpartum period for many women includes sleep deprivation, maternal-neonatal bonding, breastfeeding, and integrating a new life into the family unit. Factors which impact inpatient quality of recovery include pain, nausea or vomiting, dizziness, shivering, comfort, mobilization, ability to hold and feed the baby, personal hygiene maintenance, and feeling in control. Outpatient recovery domains include psychosocial distress, surgical/medical factors, feeding and breast health, psychosocial support, pain, physical function, sleep, motherhood experience, infant health, fatigue, appearance / cosmetic factors, sexual function, and cognition. Postpartum recovery is likely to take longer than six weeks; however, no consensus regarding recovery duration exists among professional societies. Obstetric quality of recovery (ObsQoR) is a recommended measure of inpatient postpartum recovery; however, studies are needed to determine the optimum outpatient recovery assessment tool.

SUMMARY

Postpartum recovery is an important area that requires clinical and research attention. Future studies should focus on identifying and developing valid, reliable, and responsive measures of recovery as well as tracking and optimizing recovery domains following all delivery modes.

The Current Role of General Anesthesia for Cesarean Delivery

Purpose of the Review

The use of general anesthesia for cesarean delivery has declined in the last decades due to the widespread utilization of neuraxial techniques and the understanding that neuraxial anesthesia can be provided even in urgent circumstances. In fact, the role of general anesthesia for cesarean delivery has been revisited, because despite recent devices facilitating endotracheal intubation and clinical algorithms, guiding anesthesiologists facing challenging scenarios, risks, and complications of general anesthesia at the time of delivery for both mother and neonate(s) remain significant. In this review, we will discuss clinical scenarios and risk factors associated with general anesthesia for cesarean delivery and address reasons why anesthesiologists should apply strategies to minimize its use.

Recent Findings

Unnecessary general anesthesia for cesarean delivery is associated with maternal complications, including serious anesthesia-related complications, surgical site infection, and venous thromboembolic events. Racial and socioeconomic disparities and low-resource settings are major contributing factors in the use of general anesthesia for cesarean delivery, with both maternal and perinatal mortality increasing when general anesthesia is provided. In addition, more significant maternal pain and higher rates of postpartum depression requiring hospitalization are associated with general anesthesia for cesarean delivery.

Summary

Rates of general anesthesia for cesarean delivery have overall decreased, and while general anesthesia no longer is a contributing factor to anesthesia-related maternal deaths, further opportunities to reduce its use should be emphasized. Raising awareness in identifying situations and patients at risk to help avoid unnecessary general anesthesia remains crucial.

[Enhanced recovery after surgery-Does the ERAS concept keep its promises]

INTRODUCTION

Perioperative enhanced recovery after surgery (ERAS) concepts or fast-track are supposed to accelerate recovery after surgery, reduce postoperative complications and shorten the hospital stay when compared to traditional perioperative treatment.

METHODS

Electronic search of the PubMed database to identify systematic reviews with meta-analysis (SR) comparing ERAS and traditional treatment.

RESULTS

The presented SR investigated 70 randomized controlled studies (RCT) with 12,986 patients and 93 non-RCT (24,335 patients) concerning abdominal, thoracic and vascular as well as orthopedic surgery. The complication rates were decreased under ERAS following colorectal esophageal, liver and pulmonary resections as well as after implantation of hip endoprostheses. Pulmonary complications were reduced after ERAS esophageal, gastric and pulmonary resections. The first bowel movements occurred earlier after ERAS colorectal resections and delayed gastric emptying was less often observed after ERAS pancreatic resection. Following ERAS fast-track esophageal resection, anastomotic leakage was diagnosed less often as well as surgical complications after ERAS pulmonary resection. The ERAS in all studies concerning orthopedic surgery and trials investigating implantation of a hip endoprosthesis or knee endoprosthesis reduced the risk for postoperative blood transfusions. Regardless of the type of surgery, ERAS shortened hospital stay without increasing readmissions.

CONCLUSION

Numerous clinical trials have confirmed that ERAS reduces postoperative morbidity, shortens hospital stay and accelerates recovery without increasing readmission rates following most surgical operations.

Regional anaesthesia for labour, operative vaginal delivery and caesarean delivery: a narrative review

This narrative review discusses recent evidence surrounding the use of regional anaesthesia in the obstetric setting, including intrapartum techniques for labour and operative vaginal delivery, and caesarean delivery. Pudendal nerve blockade, ideally administered by an obstetrician, should be considered for operative vaginal delivery if neuraxial analgesia is contraindicated. Regional techniques are increasingly utilised in clinical practice for caesarean delivery to minimise opioid consumption, reduce pain, improve postpartum recovery and facilitate earlier discharge as part of enhanced recovery protocols. The evidence surrounding transversus abdominis plane and quadratus lumborum blockade supports their use when: long-acting neuraxial opioids cannot be administered due to contraindications; if emergency delivery necessitates general anaesthesia; or as a postoperative rescue technique. Current data suggest quadratus lumborum blockade is no more effective than transversus abdominis plane blockade after caesarean delivery. Transversus abdominis plane blockade, wound catheter insertion and single shot wound infiltration are all effective techniques for reducing postoperative opioid consumption, with transversus abdominis plane blockade favoured, followed by wound catheters and then wound infiltration. Ilio-inguinal and iliohypogastric, erector spinae plane and rectus sheath blockade all require further studies to determine their efficacy for caesarean delivery in the presence or absence of long-acting neuraxial opioids. Future studies are needed to: compare approaches for individual techniques; determine which combinations of techniques and dosing regimens result in optimal analgesic and recovery outcomes following delivery; and elucidate the populations that benefit most from regional anaesthesia in the obstetric setting.
