The influence of race and socioeconomic factors on patient acceptance of perioperative epidural analgesia

The Impact of Race/Ethnicity on Disparities in Utilization and Outcomes of Neuraxial Anesthesia for Hip and Femoral Shaft Fractures

Background/Objectives: The use of neuraxial anesthesia versus general anesthesia for hip fracture surgery remains an active area of research, with recent studies demonstrating mixed findings supporting neuraxial over general anesthesia. The benefits of neuraxial anesthesia have been documented in associated surgeries, including total joint arthroplasty. However, racial disparities in the administration of neuraxial anesthesia have been identified in numerous procedures. We aimed to examine the association of race/ethnicity with neuraxial anesthesia use and the effect of neuraxial anesthesia on length of stay, non-home discharge, 30-day severe adverse events, and rates of readmission among patients undergoing isolated hip and femoral shaft fracture operations. Methods: The American College of Surgeons National Quality Improvement Program database was queried for isolated hip or femoral shaft fractures from 2015 to 2019. Stepwise logistic regression was performed to assess the relationship between race/ethnicity and neuraxial anesthesia use. Within each sex-race stratum, neuraxial anesthesia recipients were propensity-matched to general anesthesia recipients in a 1:2 ratio. Logistic regression and negative binomial regression were performed on the propensity-matched cohort. Results: A total of 12,004 neuraxial and 64,250 general anesthesia hip and femoral shaft fracture patients were identified. Compared to White patients, Black and Hispanic patients were between 0.64 and 0.61 times less likely to receive neuraxial anesthesia over general anesthesia, respectively (p < 0.05). 11,993 patients who received neuraxial anesthesia were propensity matched to 23,946 patients who received general anesthesia. Propensity-matched logistic regressions found that neuraxial anesthesia was associated with decreased length of stay, 30-day severe adverse events, and acute rehab/skilled nursing facility discharge for White patients (p < 0.05 for all), but only decreased length of stay in Black and Hispanic patients (p = 0.01 and p = 0.02, respectively). Conclusions: Notable disparities exist in the administration of neuraxial anesthesia for isolated hip and femoral shaft fracture patients. Hispanic and Black race/ethnicity in particular influences provision of neuraxial anesthesia. Further research is required to understand the degree of effect modification and root causes of regional anesthesia access and benefits for this high-volume patient population.

Differences in the Receipt of Regional Anesthesia Based on Race and Ethnicity in Colorectal Surgery

BACKGROUND

Health equity in pain management during the perioperative period continues to be a topic of interest. The authors evaluated the association of race and ethnicity with regional anesthesia in patients who underwent colorectal surgery and characterized trends in regional anesthesia.

METHODS

Using the American College of Surgeons National Surgical Quality Improvement Program database from 2015 to 2020, the research team identified patients who underwent open or laparoscopic colorectal surgery. Associations between race and ethnicity and use of regional anesthesia were estimated using logistic regression models.

RESULTS

The final sample size was 292,797, of which 15.6% (n = 45,784) received regional anesthesia. The unadjusted rates of regional anesthesia for race and ethnicity were 15.7% white, 15.1% Black, 12.8% Asian, 29.6% American Indian or Alaska Native, 16.3% Native Hawaiian or Pacific Islander, and 12.4% Hispanic. Black (odds ratio [OR] 0.93, 95% confidence interval [CI] 0.90-0.96, p < 0.001) and Asian (OR 0.76, 95% CI 0.71-0.80, p < 0.001) patients had lower odds of regional anesthesia compared to white patients. Hispanic patients had lower odds of regional anesthesia compared to non-Hispanic patients (OR 0.72, 95% CI 0.68-0.75, p < 0.001). There was a significant annual increase in regional anesthesia from 2015 to 2020 for all racial and ethnic cohorts (p < 0.05).

CONCLUSION

There was an annual increase in the use of regional anesthesia, yet Black and Asian patients (compared to whites) and Hispanics (compared to non-Hispanics) were less likely to receive regional anesthesia for colorectal surgery. These differences suggest that there are racial and ethnic differences in regional anesthesia use for colorectal surgery.

The Effect of Adolescent Idiopathic Scoliosis on Natural Delivery and Epidural Use in Pregnant Females: A Matched Cohort Study

STUDY DESIGN

Retrospective matched cohort study.

OBJECTIVE

The aim of this study was to determine whether females with idiopathic scoliosis (IS), both with and without spine fusion, experience different rates of cesarean section (CS) and epidural anesthesia (EA) than females without scoliosis.

SUMMARY OF BACKGROUND DATA

IS is a common spine condition with a higher prevalence in females. It is unclear whether females with scoliosis, treated nonoperatively or operatively, have different rates of cesarean delivery or EA.

MATERIALS AND METHODS

Patients with IS who delivered in our integrated health care system during a 6-year period were identified (N = 1810). They were matched with a group without scoliosis who delivered during the same period (N = 1810). Rates and relative risk (RR) of CS and EA between cohorts and subgroups were calculated.

RESULTS

The scoliosis cohort had significantly higher rates and RR of EA ( P = 0.002 and P = 0.004, respectively). Scoliosis patients treated nonoperatively had an 8% greater RR of EA ( P = 0.004) and had a significantly lower rate of CS (23.2% vs . 26%, P = 0.048) compared with the control group. Among only scoliosis patients, those treated with spine fusion had a 38% decreased RR of EA ( P < 0.001). Distal fusion level did not seem to influence the RR of EA or CS.

CONCLUSIONS

Females with scoliosis were significantly more likely to receive EA at delivery compared with females without scoliosis. Rates and RR of cesarean delivery were not significantly lower among women with scoliosis, but females treated nonoperatively for scoliosis had a significantly lower CS rate than those without scoliosis. Females treated with spine fusion for scoliosis were far less likely to receive EA than both females without scoliosis and females with scoliosis treated nonoperatively.

Racial Inequity in Pediatric Anesthesia

Purpose of Review

Minority health disparities have received renewed attention in the USA following several highly publicized racial injustices in 2020. Though the focus has been largely on adults, children are not immune to these inequities. By reviewing racial disparities in pediatric perioperative care, we aim to engage the anesthesia community in the fight against systemic racism.

Recent Findings

Minority children have higher rates of anesthetic and surgical morbidity compared to White children, including respiratory events, length of stay, hospital costs, and even death. These inequities occur across surgical specialties and environments.

Summary

Racial disparities in the perioperative health and management of children are ubiquitous. Herein, we will summarize recent pediatric health disparity literature, discuss some important contributors to persistent inequities, and propose avenues for anesthesiologists to impact the pursuit of equitable healthcare outcomes.

Impact of maternal neuraxial labor analgesia exposure on offspring's neurodevelopment: A longitudinal prospective cohort study with propensity score matching

Background

Neuraxial analgesia is widely used to relieve labor pain; its effects on long-term neurodevelopment of offspring remain unclear. This study was designed to investigate the influence of maternal neuraxial labor analgesia on offspring mental development.

Methods

This was a predefined secondary analysis of a 2-year prospective longitudinal study. Nulliparous women with single-term cephalic pregnancy preparing for vaginal delivery self-selected neuraxial analgesia or not during labor. Mothers and their offspring were followed up 2 years later. children's mental development was assessed with the bayley scales of infant development. A multivariable logistic model was used to identify factors associated with below-average mental development (Mental Development Index <90).

Results

A Total of 508 pairs of mothers and children completed a 2-year follow-up. after propensity score matching, 387 pairs were included in the analysis. In both cohorts, the proportions with below-average mental development were slightly lower in children whose mothers received neuraxial labor analgesia, although not statistically significant [in the full cohort: 9.8 % (36/368) vs. 15.7% (22/140), P = 0.060; In the matched cohort: 8.3% (21/254) vs. 14.3% (19/133), P = 0.065]. A higher 2-year depression score (in the full cohort: Odds Ratio 1.15, 95% CI 1.08–1.22, P < 0.001; In the matched cohort: Odds Ratio 1.09, 95% CI 1.01–1.18, P = 0.037), but not neuraxial analgesia exposure, was associated with an increased risk of below-average mental development.

Conclusions

Maternal depression at 2 years was associated with the risk of below-average mental development, whereas maternal exposure to neuraxial labor analgesia was not.

Clinical Trial Registration

The study was registered with www.chictr.org.cn (ChiCTR-OCH-14004888) and ClinicalTrials.gov (NCT02823418).

An Update on Racial and Ethnic Differences in Neuraxial Anesthesia for Cesarean Delivery

Background Racial and ethnic differences in the use of neuraxial anesthesia compared with general anesthesia are less studied, particularly in obstetrical anesthesia. Here, we aimed to provide an update on the association between race and ethnicity, and the use of neuraxial anesthesia for cesarean delivery in the United States (US). Methods We used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Participant Use Data File 2019. We extracted cases that had a primary surgery defined with Current Procedural Terminology (CPT) code for cesarean delivery (59510, 59514, and 59515) and cesarean after attempted vaginal delivery in parturients with a prior history of cesarean (59618, 59620, and 59622). Multivariable logistic regression was used to report the association of race and ethnicity with primary anesthetic technique. Results There were 12,876 parturients included in the study. Compared with White parturients, Black (adjusted odds ratio (aOR) = 0.71, 95% confidence interval (CI): 0.57-0.88, p = 0.001) and American Indian or Alaska Native (aOR = 0.22, 95% CI: 0.12-0.40, p < 0.001) parturients had lower odds of receiving neuraxial compared with general anesthesia. There were no significant differences in the odds of neuraxial anesthesia between non-Hispanic and Hispanic cohorts. Conclusions While we do observe racial differences in anesthetic technique, Hispanic patients did not have significantly lower odds of neuraxial anesthesia. This study highlights the importance of an update to prior studies, as the current study suggests a lack of disparity between non-Hispanic and Hispanic parturients. While the results here are encouraging, a multidisciplinary approach is necessary to further address racial disparities.

Racial and Ethnic Disparities in Access to Local Anesthesia for Inguinal Hernia Repair

BACKGROUND

Many studies have identified racial disparities in healthcare, but few have described disparities in the use of anesthesia modalities. We examined racial disparities in the use of local versus general anesthesia for inguinal hernia repair. We hypothesized that African American and Hispanic patients would be less likely than Caucasians to receive local anesthesia for inguinal hernia repair.

MATERIALS AND METHODS

We included 78,766 patients aged ≥ 18 years in the Veterans Affairs Surgical Quality Improvement Program database who underwent elective, unilateral, open inguinal hernia repair under general or local anesthesia from 1998-2018. We used multiple logistic regression to compare use of local versus general anesthesia and 30-day postoperative complications by race/ethnicity.

RESULTS

In total, 17,892 (23%) patients received local anesthesia. Caucasian patients more frequently received local anesthesia (15,009; 24%), compared to African Americans (2353; 17%) and Hispanics (530; 19%), P < 0.05. After adjusting for covariates, we found that African Americans (OR 0.82, 95% CI 0.77-0.86) and Hispanics (OR 0.77, 95% CI 0.69-0.87) were significantly less likely to have hernia surgery under local anesthesia compared to Caucasians. Additionally, local anesthesia was associated with fewer postoperative complications for African American patients (OR 0.46, 95% CI 0.27-0.77).

CONCLUSIONS

Although local anesthesia was associated with enhanced recovery for African American patients, they were less likely to have inguinal hernias repaired under local than Caucasians. Addressing this disparity requires a better understanding of how surgeons, anesthesiologists, and patient-related factors may affect the choice of anesthesia modality for hernia repair.

Neuraxial Analgesia in Pregnant Hispanic Women: An Assessment of Their Beliefs and Expectations

Background

The presence of racial/ethnic disparities in the use of neuraxial labor analgesia for childbirth has been previously described. The purpose of this study was to assess the childbirth pain management beliefs among a small sample of pregnant Hispanic women and to evaluate the Spanish translation accuracy of the Childbirth Pain Scale (CPBS).

Methods

To collect data, we interviewed 20 pregnant Spanish-speaking women using an interview guide, a demographic datasheet, and the CPBS a 15-item survey. Interviews were transcribed verbatim, translated, and uploaded to ethnograph v6. Descriptive statistics and thematic analysis were used to analyze the data.

Results

Most of the participants were from Mexico (n=16) and Central America (n=4), mean age was 28.3, and all (n=20) spoke Spanish as their primary language. In this sample, 80% of nulliparous and 100% of multiparous women saw pain as having a positive role in delivery. Four major themes emerged from the data: Theme 1: Normalcy of childbirth pain (pain is good), Theme 2: Availability and role of pain medication, Theme 3: Naturalistic strategies to endure pain, and Theme 4: Fear of the unknown/childbirth process. In this sample, 18 of 20 women stated they did not want epidural analgesia unless medically indicated. During labor and delivery 100% of nulliparous and 25% of multiparas chose to receive epidural analgesia. No changes were requested by the participants regarding the translation of the CPBS.

Conclusion

Childbirth pain was seen as a valuable component of the birthing process. The majority of participants believed pain medication should be avoided unless medically necessary. These results suggest that racial/ethnic disparities in the use of epidural analgesia may partially reflect patient beliefs and preferences. It is crucial to be aware of these differences to optimize shared decision-making for women in this vulnerable patient population.

The Utilization of Regional Anesthesia Among Pediatric Patients: A Retrospective Study

BACKGROUND

The use of regional anesthesia (RA) in pediatric patients remains understudied, although evidence suggests benefits over general anesthesia.

QUESTIONS/PURPOSES

We sought to identify factors associated with RA use in patients under the age of 21 years undergoing ambulatory orthopedic surgery.

METHODS

Patients under the age of 21 who underwent anterior cruciate ligament (ACL) repair or reconstruction, knee arthroscopy (KA), or shoulder arthroscopy (SA) were identified from the NY Statewide Planning and Research Cooperative System (SPARCS) database (2005-2015). Frequencies of RA use (defined by femoral nerve block, spinal, epidural, caudal, or brachial plexus anesthesia) were calculated. Multivariable regression analysis identified patient- and healthcare system-related factors associated with the use of RA. Odds ratios (OR) and 95% confidence intervals (CI) were reported.

RESULTS

We identified 87,273 patients who underwent the procedures of interest (ACL n = 28,226; SA n = 18,155; KA n = 40,892). In our primary analysis, 14.4% (n = 1404) had RA as their primary anesthetic; this percentage increased for patients who had ACL or KA. When adjusting for covariates, Hispanic ethnicity (OR 0.78; CI 0.65-0.94) and Medicaid insurance (OR 0.75; CI 0.65-0.87) were associated with decreased odds for the provision of RA. Further, we identified increasing age (OR 1.10; CI 1.08-1.11), ACL versus SA (OR 1.91; CI 1.74-2.10), and sports injuries (OR 1.20; CI 1.10-1.31) as factors associated with increased odds of RA use.

CONCLUSION

In this analysis, RA was used in a minority of patients under the age of 21 undergoing ambulatory orthopedic surgery. Older age was associated with increased use while Hispanic ethnicity and lower socioeconomic status were associated with lower use.

Association Between Race and Ethnicity in the Delivery of Regional Anesthesia for Pediatric Patients: A Single-Center Study of 3189 Regional Anesthetics in 25,664 Surgeries

BACKGROUND

Racial and ethnic disparities in health care are well documented in the United States, although evidence of disparities in pediatric anesthesia is limited. We sought to determine whether there is an association between race and ethnicity and the use of intraoperative regional anesthesia at a single academic children's hospital.

METHODS

We performed a retrospective review of all anesthetics at an academic tertiary children's hospital between May 4, 2014, and May 31, 2018. The primary outcome was delivery of regional anesthesia, defined as a neuraxial or peripheral nerve block. The association between patient race and ethnicity (white non-Hispanic or minority) and receipt of regional anesthesia was assessed using multivariable logistic regression. Sensitivity analyses were performed comparing white non-Hispanic to an expansion of the single minority group to individual racial and ethnic groups and on patients undergoing surgeries most likely to receive regional anesthesia (orthopedic and urology patients).

RESULTS

Of 33,713 patient cases eligible for inclusion, 25,664 met criteria for analysis. Three-thousand one-hundred eighty-nine patients (12.4%) received regional anesthesia. One thousand eighty-six of 8884 (13.3%) white non-Hispanic patients and 2003 of 16,780 (11.9%) minority patients received regional anesthesia. After multivariable adjustment for confounding, race and ethnicity were not found to be significantly associated with receiving intraoperative regional anesthesia (adjusted odds ratios [ORs] = 0.95; 95% confidence interval [CI], 0.86-1.06; P = .36). Sensitivity analyses did not find significant differences between the white non-Hispanic group and individual races and ethnicities, nor did they find significant differences when analyzing only orthopedic and urology patients, despite observing some meaningful clinical differences.

CONCLUSIONS

In an analysis of patients undergoing surgical anesthesia at a single academic children's hospital, race and ethnicity were not significantly associated with the adjusted ORs of receiving intraoperative regional anesthesia. This finding contrasts with much of the existing health care disparities literature and warrants further study with additional datasets to understand the mechanisms involved.

Effect of Preperitoneal Versus Epidural Analgesia on Postoperative Inflammatory Response and Pain Following Radical Cystectomy: A Prospective, Randomized Trial

OBJECTIVES

Continuous wound infiltration of local anesthetics has been proposed as an alternative to epidural analgesia during abdominal surgery. Cytokines have a major role in inflammatory changes caused by surgery. This study aimed to compare the effects of continuous preperitoneal versus epidural analgesia on inflammatory cytokines postoperatively.

MATERIALS AND METHODS

Forty patients scheduled for radical cystectomy were included in this observer-blinded, randomized trial; patients were randomly assigned into 2 groups to receive; continuous preperitoneal wound infiltration (PPB) or epidural analgesia (EDB). Serum levels of interleukins (IL1β, IL6, IL10, and tumor necrosis factor α) were measured at baseline (before induction of anesthesia), preinfusion (before the start of local anesthetic infusion), 6 and 24 hours postoperatively. Visual Analog Scale at rest/movement (VAS-R/M), time to the first request of analgesia, total morphine consumption, sedation score, hemodynamics, and side effects were observed 24 hours postoperatively.

RESULTS

There was a significant reduction in IL6, IL1β and increase in IL10 in PPB compared with EDB at 6 and 24 hours postoperatively and compared with preinfusion levels (P≤0.001). In EDB, a significant increase in IL1β, IL10, and tumor necrosis factor α at 6 hours compared with preinfusion levels (P≤0.002). VAS-R/M was significantly decreased at 2, 4, 6, 8, and 12 hours in EDB compared with PPB (P≤0.014), with no significant difference in the mean time to the first request of analgesia and total morphine consumption between the 2 groups.

CONCLUSION

Continuous preperitoneal analgesia better attenuated postoperative inflammatory response and provided a comparable overall analgesia to that with continuous epidural analgesia following radical cystectomy.

Parents Demand and Teenager Refuses Epidural Anesthesia

A 15-year-old girl is scheduled to undergo an upper lobectomy to debulk metastatic Ewing sarcoma. The anesthesiologist recommended placement of a thoracic epidural catheter to provide postoperative analgesia. The patient did not want a needle to be placed near her spine. She was terrified that the procedure would be painful and that it might paralyze her. Although the anesthesiologist reassured her that sedation and local anesthesia would make the procedure comfortable, she remained vehemently opposed to the epidural procedure. The parents spoke privately to the anesthesiologist and asked for placement of the epidural after she was asleep. They firmly believed that this would provide optimal postoperative analgesia and thus would be in her best interest. Experts discuss the pros and cons of siding with the patient or parents.

A retrospective evaluation of the impact of patient ethnicity on the use of epidural analgesia or blood transfusions in children undergoing major oncologic surgery

Background

The impact of patient ethnicity on healthcare delivery is well documented. In this study of children who had undergone open abdominal or pelvic surgery for tumor resection, we sought to compare the use of epidural analgesia or intraoperative blood transfusions between Caucasian and non-Caucasian children.

Methods

A retrospective study of 139 children was performed. Logistic regression models were used to evaluate the association between the specified perioperative factors and patient ethnicity.

Results

The average age (standard deviation) was 11 years (± 5), 50% were female, and 58% were Caucasian. Compared to Caucasian children, non-Caucasian children were younger (difference in mean, − 2.6 years; 95% confidence interval [− 4.3, − 0.9], p = 0.003), underwent shorter procedures (difference in mean anesthesia minutes, − 134; 95% confidence interval [−  230, − 39], p = 0.006), and had a lower proportion of patients who received epidural analgesia (66% versus 81%, p = 0.042) or blood transfusions (48% versus 65%, p = 0.039). In the adjusted model, patient ethnicity was not associated with the receipt of epidural analgesia (odds ratio 0.53, 95% confidence interval [0.23, 1.21], p = 0.132) or blood transfusions (odds ratio 0.77, 95% confidence interval [0.29, 2.04], p = 0.600). The use of epidural analgesia or blood transfusions was associated with abnormal coagulation factors (odds ratio 0.32, 95% confidence interval [0.14, 0.71], p = 0.005) and the duration of surgery (odds ratio 1.007, 95% confidence interval [1.005, 1.009], p < 0.001), respectively.

Conclusion

In this study of children who had undergone major oncologic surgery, the use of epidural analgesia or blood transfusions was not associated with patient ethnicity.

Pain Management for Older African Americans in the Perianesthesia Setting: The "Eight I's"

National legislation (Affordable Care Act) emphasizes quality and equitable pain care for all patient populations, but frequently, pain management is not effective and equitable in African American (AA) elders, placing them at higher risk for severe pain and persistent pain. Research shows that AAs are less likely to receive guideline-based pain care. This underscores the need for perianesthesia nurses to be knowledgeable and capable of integrating cultural practices and evidence-based recommendations into their care of older AAs to ensure adequate pain management in this vulnerable population. This article describes differences and disparities in pain management in AA older adults and provides a cultural framework to guide perianesthesia pain management.

Continuous wound infiltration versus epidural analgesia after hepato-pancreato-biliary surgery (POP-UP): a randomised controlled, open-label, non-inferiority trial

BACKGROUND

Epidural analgesia is the international standard for pain treatment in abdominal surgery. Although some studies have advocated continuous wound infiltration with local anaesthetics, robust evidence is lacking, especially on patient-reported outcome measures. We aimed to determine the effectiveness of continuous wound infiltration in hepato-pancreato-biliary surgery.

METHODS

In this randomised controlled, open label, non-inferiority trial (POP-UP), we enrolled adult patients undergoing hepato-pancreato-biliary surgery by subcostal or midline laparotomy in two Dutch hospitals. Patients were centrally randomised (1:1) to receive either pain treatment with continuous wound infiltration using bupivacaine plus patient-controlled analgesia with morphine or to receive (patient-controlled) epidural analgesia with bupivacaine and sufentanil. All patients were treated within an enhanced recovery setting. Randomisation was stratified by centre and type of incision. The primary outcome was the mean Overall Benefit of Analgesic Score (OBAS) from day 1-5, a validated composite endpoint of pain scores, opioid side-effects, and patient satisfaction (range 0 [best] to 28 [worst]). Analysis was per-protocol. The non-inferiority limit of the mean difference was + 3·0. This trial is registered with the Netherlands Trial Registry, number NTR4948.

FINDINGS

Between Jan 20, 2015, and Sept 16, 2015, we randomly assigned 105 eligible patients: 53 to receive continuous wound infiltration and 52 to receive epidural analgesia. One patient in the continuous wound infiltration group discontinued treatment, as did five in the epidural analgesia group; of these five patients, preoperative placement failed in three (these patients were treated with continuous wound infiltration instead), one patient refused an epidural, and data for the primary endpoint was lost for one. Thus, 55 patients were included in the continuous wound infiltration group and 47 in the epidural analgesia group for the per-protocol analyses. Mean OBAS was 3·8 (SD 2·4) in the continuous wound infiltration group versus 4·4 (2·2) in the epidural group (mean difference -0·62, 95% CI -1·54 to 0·30). Because the upper bound of the one-sided 95% CI did not exceed +3·0, non-inferiority was shown. Four (7%) patients in the continuous wound infiltration group and five (11%) of those in the epidural group had an adverse event. One patient in the continuous wound infiltration group had a serious adverse event (temporary hypotension and arrhythmia after bolus injection); no serious adverse events were noted in the epidural group.

INTERPRETATION

These data suggest that continuous wound infiltration is non-inferior to epidural analgesia in hepato-pancreato-biliary surgery within an enhanced recovery setting. Further large-scale trials are required to make a definitive assessment of non-inferiority.

Racial differences in veterans' satisfaction with examination of disability from posttraumatic stress disorder

OBJECTIVE

The examination that determines if a veteran has service-connected posttraumatic stress disorder (PTSD) affects veterans' lives for years. This study examined factors potentially associated with veterans' perception of their examination's quality.

METHODS

Veterans (N=384) being evaluated for an initial PTSD service-connection claim were randomly assigned to receive either a semistructured interview or the examiner's usual interview. Immediately after the interview, veterans completed confidential ratings of the examinations' quality and of their examiners' interpersonal qualities and competence. Extensive data characterizing the veterans, the 33 participating examiners, and the examinations themselves were collected.

RESULTS

Forty-seven percent of Caucasian veterans and 34% of African-American veterans rated their examination quality as excellent. African Americans were less likely than Caucasians to assign a higher quality rating (odds ratio=.61, 95% confidence interval=.38-.99, p=.047). Compared with Caucasians, African Americans rated their examiners as having significantly worse interpersonal qualities but not lower competence. Ratings were not significantly related to the veterans' age, gender, marital status, eventual diagnosis of PTSD, Global Assessment of Functioning score, the examiner's perception of the prevalence of malingering, or the presence of a third party during the examination.

CONCLUSIONS

Ratings of disability examinations were generally high, although ratings were less favorable among African-American veterans than among Caucasian veterans.

Cost-effectiveness analysis comparing epidural, patient-controlled intravenous morphine, and continuous wound infiltration for postoperative pain management after open abdominal surgery

BACKGROUND

Continuous wound infiltration (CWI), i.v. patient-controlled analgesia (i.v.-PCA), and epidural analgesia (EDA) are analgesic techniques commonly used for pain relief after open abdominal surgery. The aim of this study was to evaluate the cost-effectiveness of these techniques.

METHODS

A decision analytic model was developed, including values retrieved from clinical trials and from an observational prospective cohort of 85 patients. Efficacy criteria were based on pain at rest (VAS ≤ 30/100 mm at 24 h). Resource use and costs were evaluated from medical record measurements and published data. Probabilistic sensitivity analysis (PSA) was performed.

RESULTS

When taking into account all resources consumed, the CWI arm (€ 6460) is economically dominant when compared with i.v.-PCA (€ 7273) and EDA (€ 7500). The proportion of patients successfully controlled for their postoperative pain management are 77.4%, 53.9%, and 72.9% for CWI, i.v.-PCA, and EDA, respectively, demonstrating the CWI procedure to be both economically and clinically dominant. PSA reported that CWI remains cost saving in 70.4% of cases in comparison with EDA and in 59.2% of cases when compared with PCA.

CONCLUSIONS

Device-related costs of using CWI for pain management after abdominal laparotomy are partly counterbalanced by a reduction in resource consumption. The cost-effectiveness analysis suggests that CWI is the dominant treatment strategy for managing postoperative pain (i.e. more effective and less costly) in comparison with i.v.-PCA. When compared with EDA, CWI is less costly with almost equivalent efficacy. This economic evaluation may be useful for clinicians to design algorithms for pain management after major abdominal surgery.

Preoperative consultations by anesthesiologists

PURPOSE OF REVIEW

Preoperative anesthesia consultation before major surgery presents opportunities to better document comorbid illness, optimize medical conditions, facilitate referrals to specialists, order specialized investigations, initiate interventions to decrease risk, discuss aspects of perioperative care, and arrange appropriate postoperative care. The goal of this review is to discuss the implications of recent studies that have evaluated the processes-of-care and outcomes related to preoperative anesthesia consultation.

RECENT FINDINGS

An increasing proportion of surgical patients undergo outpatient preoperative anesthesia consultation. These consultations effectively communicate information to anesthesia providers in operating rooms, reduce the time required to complete preoperative assessments, improve patients' education about perioperative care, and increase patient acceptance of regional anesthesia. Recent population-based data also demonstrate that consultations are associated with reductions in hospital length-of-stay, but not postoperative mortality. In addition, rates of specialized preoperative cardiac testing are increased following anesthesia consultation but the value of these tests remains debatable.

SUMMARY

Preoperative anesthesia consultations have become increasingly common and have shown some clear beneficial effects on perioperative care and outcomes. Further research remains needed to identify efficacious interventions for reducing perioperative risk, measure the prognostic value of specialized preoperative tests, and compare the safety of different models for performing preoperative consultations.

Social disparity and the use of intrapartum epidural analgesia in a publicly funded health care system

OBJECTIVE

We sought to examine the difference in use of labor epidural analgesia among women from different neighborhood socioeconomic groups.

STUDY DESIGN

Neighborhood socioeconomic variables from the 2001 Canadian Census were linked to singleton vaginal births from the Niday perinatal database (2004-2006) in Ontario, Canada. Births were divided into income and education groups by quintiles. Generalized estimating equations were employed to evaluate the association between labor epidural and neighborhood socioeconomic status. Supplementary analysis was conducted after stratifying data by hospital types.

RESULTS

Compared with those from the richest neighborhood, women from the poorest quintile were the least likely to receive labor epidural analgesia (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.58-0.61). The differences were smallest in teaching hospitals (OR, 0.73; 95% CI, 0.67-0.79) and largest in small community hospitals (OR, 0.57; 95% CI, 0.50-0.64). Similar association was found in neighborhood education quintiles.

CONCLUSION

The use of labor epidural analgesia is decreased with decreasing neighborhood economic and education levels.

Epidural anaesthesia and survival after intermediate-to-high risk non-cardiac surgery: a population-based cohort study

BACKGROUND

Although epidural anaesthesia and analgesia have numerous benefits, their effects on postoperative survival are unclear. We therefore undertook a population-based cohort study to determine whether perioperative epidural anaesthesia or analgesia is associated with improved 30-day survival.

METHODS

We used population-based linked administrative databases to do a retrospective cohort study of 259 037 patients, aged 40 years or older, who underwent selected elective intermediate-to-high risk non-cardiac surgical procedures between April 1, 1994, and March 31, 2004, in Ontario, Canada. Propensity-score methods were used to construct a matched-pairs cohort that reduced important baseline differences between patients who received epidural anaesthesia or analgesia as opposed to those that did not. We then determined the association of epidural anaesthesia with 30-day mortality within these matched-pairs.

FINDINGS

Of the 259 037 patients, 56 556 (22%) received epidural anaesthesia. Within the matched-pairs cohort (n=88 188), epidural anaesthesia was associated with a small reduction in 30-day mortality (1.7%vs 2.0%; relative risk 0.89, 95% CI 0.81-0.98, p=0.02).

INTERPRETATION

Epidural anaesthesia and analgesia were associated with a small improvement in 30-day survival, but this effect should be interpreted cautiously. The estimate had borderline significance, despite a large sample size. Its absolute magnitude was also small, corresponding to a number needed to treat of 477. Our study, therefore, does not provide compelling evidence that epidural anaesthesia improves postoperative survival. Nonetheless, our results support the safety of perioperative epidural anaesthesia when used for indications other than improving survival (eg, improving postoperative pain relief, preventing postoperative pulmonary complications).
