ABSTRACT
BACKGROUND: There is increasing interest in documenting disparities in pain management for racial and ethnic minorities and patients with language barriers. Previous studies have found differential prescription patterns of opioids for racial and ethnic minority group and patients having limited English proficiency (LEP) after arthroplasty. However, there is a knowledge gap regarding how the intersection of these sociodemographic factors is associated with immediate postoperative pain management. This study aimed to explore language and racial-ethnic disparities in short-term opioid utilization after total hip and knee arthroplasty. METHODS: We conducted a retrospective cohort study of adult patients who underwent total hip and knee arthroplasty from 2015 to 2019 at an urban medical center. The primary predictor variables included LEP status and racial-ethnic category, and the primary outcome variables were oral morphine equivalents (OMEs) during 2 distinct postoperative periods: the first 12 hours after surgery and from the end of surgery to the end of postoperative day (POD) 1. Patient characteristics and perioperative metrics were described by language status, race, and ethnicity using nonparametric tests, as appropriate. We performed an adjusted generalized estimating equation to assess the total effect of the intersection of LEP and racial-ethnic categories on short-term postoperative opioid use in mean ratios (MRs). RESULTS: This study included a total of 4090 observations, in which 7.9% (323) patients had LEP. Patients reported various racial-ethnic categories, with 72.7% (2975) non-Hispanic White, and minority groups including non-Hispanic Asian and Pacific Islander (AAPI), Hispanic/Latinx, non-Hispanic Black/African American, and Others. Patients self-identifying as non-Hispanic AAPI received fewer OME regardless of LEP status during the first 12 hours postoperatively (MR for English proficient [EP], 0.12 [95% confidence interval, CI, 0.08-0.18]; MR for LEP, 0.22 [95% CI, 0.13-0.37]) and from end of surgery to the end of POD 1 (MR for EP, 0.24 [95% CI, 0.16-0.37]; MR for LEP, 0.42, [95% CI, 0.24-0.73]) than EP non-Hispanic White. Hispanic/Latinx patients with LEP received lower amounts of OME during the first postoperative 12 hours (MR, 0.29; 95% CI, 0.17-0.53) and from end of surgery to the end of POD 1 (MR, 0.42; 95% CI 0.23-0.79) than EP non-Hispanic White. Furthermore, within the non-Hispanic White group, those with LEP received fewer OME within the first 12 hours (MR, 0.33; 95% CI, 0.13-0.83). CONCLUSIONS: We identified an association between LEP, racial-ethnic identity, and short-term postoperative OME utilization after total knee and hip arthroplasty. The observed differences in opioid utilization imply there may be language and racial-ethnic disparities in acute pain management and perioperative care.
ABSTRACT
BACKGROUND: A well-known complication of laparoscopic management of gynaecologic masses and cancers is the need to perform an intraoperative conversion to laparotomy. The purpose of this study was to identify novel patient risk factors for conversion from minimally invasive to open surgeries for gynaecologic oncology operations. METHODS: This was a retrospective cohort study of 1356 patients ≥18 years of age who underwent surgeries for gynaecologic masses or malignancies between February 2015 and May 2020 at a single academic medical centre. Multivariable logistic regression was used to study the effects of older age, higher body mass index (BMI), higher American Society of Anaesthesiologist (ASA) physical status, and lower preoperative haemoglobin (Hb) on odds of converting from minimally invasive to open surgery. Receiver operating characteristic (ROC) curve analysis assessed the discriminatory ability of a risk prediction model for conversion. RESULTS: A total of 704 planned minimally invasive surgeries were included with an overall conversion rate of 6.1% (43/704). Preoperative Hb was lowest for conversion cases, compared to minimally invasive and open cases (11.6 ± 1.9 vs 12.8 ± 1.5 vs 11.8 ± 1.9 g/dL, p<.001). Patients with preoperative Hb <10 g/dL had an adjusted odds ratio (OR) of 3.94 (CI: 1.65-9.41, p=.002) for conversion while patients with BMI ≥30 kg/m2 had an adjusted OR of 2.86 (CI: 1.50-5.46, p=.001) for conversion. ROC curve analysis using predictive variables of age >50 years, BMI ≥30 kg/m2, ASA physical status >2, and preoperative haemoglobin <10 g/dL resulted in an area under the ROC curve of 0.71. Patients with 2 or more risk factors were at highest risk of requiring an intraoperative conversion (12.0%). CONCLUSIONS: Lower preoperative haemoglobin is a novel risk factor for conversion from minimally invasive to open gynaecologic oncology surgeries and stratifying patients based on conversion risk may be helpful for preoperative planning.
Minimally invasive surgery for management of gynaecologic masses (masses that affect the female reproductive organs) is often preferred over more invasive surgery, because it involves smaller surgical incisions and can have overall better recovery time. However, one unwanted complication of minimally invasive surgery is the need to unexpectedly convert the surgery to an open surgery, which entails a larger incision and is a higher risk procedure. In our study, we aimed to find patient characteristics that are associated with higher risk of converting a minimally invasive surgery to an open surgery. Our study identified that lower levels of preoperative haemoglobin, the protein that carries oxygen within red blood cells, is correlated with higher risk for conversion. This new risk factor was used with other known risk factors, including having higher age, higher body mass index, and higher baseline medical complexity to create a model to help surgical teams identify high risk patients for conversion. This model may be useful for surgical planning before and during the operation to improve patient outcomes.

Purpose of review: To review how anecdote and narrative medicine, primary cohort studies, epidemiological studies, and the dementia literature can be bridged to understand long-term postoperative cognitive decline. Recent findings: Primary cohort studies have measured recoverable declines in memory and executive function after major surgery, but less-appreciated sources also offer critical insights. Anecdote reveals that functionally-impactful cognitive decline may persist after physical recovery in some patients despite modern medications and monitoring, and that physicians are unprepared to address patients' cognitive concerns. However, epidemiological studies reproducibly demonstrate that elective surgery has no, or a negligible, average impact on cognition in older patients. Cognitively provocative factors - like medical hospital admissions or health factors like diabetes and smoking - are common in late life, and surgery likely contributes minimally to long-term cognitive change for most patients. Summary: Patients should be reassured that, while anecdotes of durable cognitive change after surgery are easily accessible, most patients experience cognitive recovery after major surgery. However, those who do not recover deserve characterization of their symptoms and investigation of modifiable causes to facilitate cognitive recovery.
ABSTRACT
OBJECTIVES: We reviewed the operational definitions of colorectal cancer (CRC) from studies using the Korean National Health Insurance Service (NHIS) and compared CRC incidence derived from the commonly used operational definitions in the literature with the statistics reported by the Korea Central Cancer Registry (KCCR). METHODS: We searched the MEDLINE and KoreaMed databases to identify studies containing operational definitions of CRC, published until January 15, 2021. All pertinent data concerning the study period, the utilized database, and the outcome variable were extracted. Within the NHIS-National Sample Cohort, age-standardized incidence rates (ASRs) of CRC were calculated for each operational definition found in the literature between 2005 and 2019. These rates were then compared with ASRs from the KCCR. RESULTS: From the 62 eligible studies, 9 operational definitions for CRC were identified. The most commonly used operational definition was "C18-C20" (n=20), followed by "C18-C20 with claim code for treatment" (n=3) and "C18-C20 with V193 (code for registered cancer patients' payment deduction)" (n=3). The ASRs reported using these operational definitions were lower than the ASRs from KCCR, except for "C18-C20 used as the main diagnosis." The smallest difference in ASRs was observed for "C18-C20," followed by "C18- C20 with V193," and "C18-C20 with claim code for hospitalization or code for treatment." CONCLUSIONS: In defining CRC patients utilizing the NHIS database, the ASR derived through the operational definition of "C18-C20 as the main diagnosis" was comparable to the ASR from the KCCR. Depending on the study hypothesis, operational definitions using treatment codes may be utilized.

Importance: English language proficiency has been reported to correlate with disparities in health outcomes. Therefore, it is important to identify and describe the association of language barriers with perioperative care and surgical outcomes to inform efforts aimed at reducing health care disparities. Objective: To examine whether limited English proficiency compared with English proficiency in adult patients is associated with differences in perioperative care and surgical outcomes. Evidence Review: A systematic review was conducted in MEDLINE, Embase, Web of Science, Sociological Abstracts, and CINAHL of all English-language publications from database inception to December 7, 2022. Searches included Medical Subject Headings terms related to language barriers, perioperative or surgical care, and perioperative outcomes. Studies that investigated adults in perioperative settings and involved quantitative data comparing cohorts with limited English proficiency and English proficiency were included. The quality of studies was evaluated using the Newcastle-Ottawa Scale. Because of heterogeneity in analysis and reported outcomes, data were not pooled for quantitative analysis. Results are reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols guideline. Findings: Of 2230 unique records identified, 29 were eligible for inclusion (281 266 total patients; mean [SD] age, 57.2 [10.0] years; 121 772 [43.3%] male and 159 240 [56.6%] female). Included studies were observational cohort studies, except for a single cross-sectional study. Median cohort size was 1763 (IQR, 266-7402), with a median limited English proficiency cohort size of 179 (IQR, 51-671). Six studies explored access to surgery, 4 assessed delays in surgical care, 14 assessed surgical admission length of stay, 4 assessed discharge disposition, 10 assessed mortality, 5 assessed postoperative complications, 9 assessed unplanned readmissions, 2 assessed pain management, and 3 assessed functional outcomes. Surgical patients with limited English proficiency were more likely to experience reduced access in 4 of 6 studies, delays in obtaining care in 3 of 4 studies, longer surgical admission length of stay in 6 of 14 studies, and more likely discharge to a skilled facility than patients with English proficiency in 3 of 4 studies. Some additional differences in associations were found between patients with limited English proficiency who spoke Spanish vs other languages. Mortality, postoperative complications, and unplanned readmissions had fewer significant associations with English proficiency status. Conclusions and Relevance: In this systematic review, most of the included studies found associations between English proficiency and multiple perioperative process-of-care outcomes, but fewer associations were seen between English proficiency and clinical outcomes. Because of limitations of the existing research, including study heterogeneity and residual confounding, mediators of the observed associations remain unclear. Standardized reporting and higher-quality studies are needed to understand the impact of language barriers on perioperative health disparities and identify opportunities to reduce related perioperative health care disparities.

ABSTRACT: Postsurgical patients usually have difficulty in answering the self-report pain scales due to the residual effects of anesthetic or sedative agents in the post-anesthesia care unit (PACU). A comparative analysis of pain assessment tools used in the PACU is lacking.In this prospective observational study, we compared the intensity of pain using the 11-point numeric rating scale (NRS) and the 4-category verbal rating scale (VRS) thrice, 5 minutes after PACU admission, 20 minutes after the first assessment, and just before discharge from the PACU in 200 patients undergone surgery. Spearman rank correlation analysis was used to investigate the correlation between 2 scales, and the weighted kappa (κ) coefficient was performed to evaluate inter-scale reliability. Response rates of the 2 scales were also compared.VRS and NRS were highly correlated during all 3 comparisons (râ=â0.767, 0.714, and 0.653, respectively; Pâ<â.0001). Each category of VRS showed a statistically significant difference in pain intensity measured by NRS during all 3 assessments. Inter-scale reliability had a fair strength of agreement for all 3 measurements (weighted κâ=â0.519, 95% CI: 0.421-0.618; weighted κâ=â0.511, 95% C.I: 0.409-0.613; weighted κâ=â0.452, 95% C.I: 0.352-0.551, respectively). VRS showed a higher response rate for PACU patients compared to NRS in all 3 measurements (96% vs 77.5%, 99% vs 81.5%, and 96.5% vs 86.5%, respectively; Pâ<â.0001).In the PACU, VRS is a reasonable and practical pain intensity measurement tool for postsurgical patients, considering the high correlation between VRS and NRS, and a higher response rate.

OBJECTIVES: Biliary tract cancers (BTCs) are rare but highly fatal. Although the etiology of BTC is poorly understood, gallstones are proposed to be a major risk factor. We conducted a systematic review and meta-analysis to examine the associations between gallstone characteristics and BTC risk. METHODS: We searched the MEDLINE, Embase, and Cochrane Central databases and systematically reviewed cohort and case-control studies published before April 9, 2018. All the included studies reported appropriate risk estimates and confidence intervals (CIs) for associations between the presence, size, number, or duration of gallstones and the risk of BTC, including gallbladder cancer (GBC), extrahepatic bile duct cancer (EBDC), and ampulla of Vater cancer (AOVC). Summary odds ratios (ORs) and their 95% CIs were calculated using a random-effects model in the meta-analysis. Subgroup analyses were conducted to inspect sources of potential heterogeneity, and the Egger test was performed to assess publication bias. RESULTS: Seven cohort studies and 23 case-control studies in Asian, European, and American populations were included. The presence of gallstones was associated with an increased risk of BTC (OR, 4.38; 95% CI, 3.23 to 5.93; I2=91.2%), GBC (OR, 7.26; 95% CI, 4.33 to 12.18), EBDC (OR, 3.17; 95% CI, 2.24 to 4.50), and AOVC (OR, 3.28; 95% CI, 1.33 to 8.11). Gallstone size (>1 vs. <1 cm; OR, 1.88; 95% CI, 1.10 to 3.22) was significantly associated with the risk of GBC. CONCLUSIONS: Gallstone characteristics, such as presence, size, and number, are associated with an increased risk of BTC. However, significantly high heterogeneity in the meta-analyses is a limitation of this study.

OBJECTIVES: The association between adjuvant chemotherapy (AC) and chronic postoperative pain (CPP) after video-assisted thoracoscopic surgery (VATS) for lung cancer resection has not yet been reported. We, therefore, investigated the association between AC and the long-term incidence of CPP after VATS. METHODS: We retrospectively reviewed 3015 consecutive patients who underwent VATS for lung cancer between 2007 and 2016. The patients were divided into 2 groups: those who received (AC group) and those who did not receive (non-AC group) AC within 3 months after VATS. Propensity score analysis was performed to adjust for baseline differences between the 2 groups. The cumulative incidence of CPP at the intervals of 3 months, over 36 months, was compared before and after matching. A Cox proportional hazards regression analysis was used to investigate the predictors of CPP after VATS. RESULTS: We included and assessed 2222 patients in this study. Of these, 320 patients (14.4%) received AC within 3 months post-VATS. The cumulative incidence of CPP during 36 months post-surgery was significantly higher in the AC group than in the non-AC group, before and after matching (log-rank test; P = 0.002 and 0.027, respectively). Cox proportional hazards regression analysis also showed that AC was a significant risk factor for CPP (hazard ratio 1.62, 95% confidence interval 1.16-2.28; P = 0.005). CONCLUSIONS: Our results indicate that AC is an important risk factor for CPP after VATS. Further understanding of the risk factors for CPP may facilitate its prediction and treatment.

BACKGROUND: The 15-item Quality of Recovery (QoR-15) scale is a validated patient-reported outcome questionnaire that measures the quality of postoperative recovery. This study aimed to validate a translated Korean version of QoR-15 (QoR-15K) in a broad range of surgical patients. METHODS: After Korean translation of the original English version of the QoR-15, we performed psychometric validation of the QoR-15K to evaluate the quality of recovery after surgery. The validity, reliability, responsiveness, and clinical feasibility of the QoR-15K were evaluated. A subgroup analysis in patients with video-assisted lung resection was performed. RESULTS: Among 193 patients, 188 (97.4%) completed the QoR-15K after surgery. We found good convergent validity between the postoperative QoR-15K and the global QoR visual analogue scale (ρ=0.61, P<0.001). The negative correlation between the QoR-15K score and the extent of surgery (ρ=-0.33, P<0.001), the duration of surgery (ρ=-0.33, P<0.001), and the severity of postoperative pain (ρ=-0.40, P<0.001) supported construct validity. The postoperative QoR-15K showed good internal consistency (Cronbach α=0.90), split-half reliability (0.81), and test-retest reliability (0.95; 95% confidence interval [CI], 0.94-0.96). The QoR-15K score decreased from 140 (preoperative, inter-quartile range [IQR] 128-146) to 100 (postoperative day 1, IQR 75-122), median difference -36.5 (95% CI, -41 to -32.5; P<0.0001). The QoR-15K indicated excellent responsiveness with Cliff's effect size -0.78 (95% CI, -0.84 to -0.71). Subgroup analysis yielded similar results. CONCLUSIONS: The QoR-15K is valid and has excellent reliability, a high degree of responsiveness, and clinical feasibility as a metric of quality of recovery in Korean surgical population. CLINICAL TRIAL REGISTRATION: NCT04169087.

Primary care is not well established in Korea despite its importance in population health. To reinforce the primary care system, understanding the public view of primary care will be essential. We aimed to compare the public perception of primary care qualities across types of healthcare facilities. We conducted a cross-sectional, web-based survey at a university in Seoul, South Korea, from October 2018 to February 2019. Using the Korean Primary Care Assessment Tool (K-PCAT), participants assessed the qualities of primary care services provided by the university health service (a university-based, patient-centered primary care model), community clinics, and hospitals. We compared K-PCAT scores across facilities and evaluated the factors associated with the differences using general linear models. A total of 5,748 responses were analyzed. K-PCAT total scores were highest for the university health service (61.0 ± 15.9) and lowest for hospitals (48.1 ± 14.5), with significant differences between facilities (P < .001). The university health service received the highest scores for first contact, comprehensiveness, personalized care, and family/community orientation; community clinics for continuity of care; and hospitals for care coordination and trust/satisfaction. Primary care facilities were rated higher than hospitals by individuals in good health, with low income levels, using ambulatory care more frequently, and spending less on medical expenses. In conclusion, the user-perceived primary care quality was higher for community-based primary care facilities than hospitals. The highest score was for the university health service, suggesting that setting-based, patient-centered primary care would be an effective model for restructuring the primary care system in Korea.

BACKGROUND: The long-term incidence of chronic postsurgical pain (CPSP) after thoracic surgery has not yet been reported. METHODS: We retrospectively reviewed the electronic medical records of 4218 consecutive patients who underwent thoracic surgery for lung cancer between 2007 and 2016. We evaluated the long-term incidence of CPSP after thoracic surgery at intervals of 3 months for 36 months. A Cox proportional hazard regression analysis was performed to investigate the predictors of CPSP after thoracic surgery. RESULTS: A total of 3200 patients were included in the analysis. Of these, 459 (14.3%) and 558 (17.4%) patients were diagnosed with CPSP within 3 and 36 months after surgery, respectively. Furthermore, the incidence of CPSP decreased over time. Additionally, 99 (3.1%) patients were newly diagnosed with CPSP at least 6 months after surgery. Female sex (HR 1.20, 95% CI 1.00 to 1.43; p=0.04), longer duration of surgery (HR 1.11, 95% CI 1.03 to 1.20; p<0.01), higher 11-point Numeric Rating Scale score at first outpatient visit after surgery (HR 1.29, 95% CI 1.24 to 1.34; p<0.001), postoperative chemotherapy (HR 1.55, 95% CI 1.26 to 1.90; p<0.001), and postoperative radiation therapy (HR 1.35, 95% CI 1.05 to 1.74; p=0.02) were significant predictors of CPSP for 36 months after surgery. CONCLUSION: Our study showed a decreasing trend in the incidence of CPSP as well as delayed-onset or recurrent CPSP after thoracic surgery. A better understanding of the progression of CPSP after thoracic surgery may provide important information on its prediction and treatment.

Many lifelong smokers establish smoking habits during young adulthood. A university can be an effective setting for early smoking cessation. We evaluated long-term predictors of smoking cessation among smokers in a university setting.We longitudinally followed a cohort of smokers enrolled in a university smoking cessation program in Seoul, South Korea. Sociodemographic factors, smoking-related variables, and changes in smoking habits were assessed during 6-week visit sessions and follow-up telephone interviews conducted 1 year or more later.A total of 205 participants were followed up (mean follow-up duration: 27.1 months). Cessation rates were 47.3% at the end of the visit sessions and 28.8% at follow-up. The long-term persistent smoking rate was significantly higher among individuals with peers who smoked (odds ratio [OR] = 8.64; 95% confidence interval [CI] = 1.75, 42.80), with family members who smoked (OR = 3.28; 95% CI = 1.20, 9.00), and who smoked 10 to 19 cigarettes/day (ORâ=â4.83; 95% CIâ=â1.49, 15.69). Conversely, persistent smoking was less likely among those who attended the program regularly (ORâ=â0.84 per visit; 95% CIâ=â0.72, 0.99) and attempted quitting more frequently (ORâ=â0.93 per attempt; 95% CIâ=â0.87, 0.99). Use of smoking cessation medications (varenicline or bupropion) was not significantly associated with long-term quitting (ORâ=â0.71; 95% CIâ=â0.26, 1.93).Peer influences were the strongest predictors of failure in long-term cessation among smokers who attempted to quit. Similarly, the existence of smokers in the family was negatively associated with successful quitting. Regular attendance at a smoking cessation program and a high number of attempts to quit were positively associated with successful quitting. Targeting peer and family smoking groups together rather than targeting individual smokers alone, implementing active cessation programs encouraging regular attendance, and providing comprehensive antismoking environments might be effective strategies in a university setting.
