The numbers of joint replacement procedures are expected to rise considerably in the coming years, so it is crucial to identify factors related to successful outcomes. The purpose of this study was to examine the association between CPC and emergency department (ED) visits after knee and hip replacement surgery. Methods: Physician claims and hospital data from 2005 to 2020 in Nova Scotia were used in this retrospective study. To measure CPC, we used the Modified Modified Continuity Index (MMCI), which is the number of primary care providers adjusted for the total number of visits. The outcome was ED visits within 90 days of discharge. Logistic regression was used to test for associations between MMCI and the probability of an ED visit. Results: There were 28 574 knee and 16 767 hip procedures in the data set; 13.9% (95% confidence interval [CI] 13.5%–14.3%) and 13.5% (95% CI 13.0%–14.0%) of the patients, respectively, had an ED visit within 90 days. For patients who underwent knee procedures, the mean MMCI was 0.868 (95% CI 0.867–0.870); 10.7% (95% CI 10.4 %–11.1 %) had perfect continuity of care. For patients who underwent hip procedures, the corresponding measures were 0.864 (95% CI 0.862–0.866) and 13.5% (95% CI 13.0%–14.0%). There was a statistically significant negative association between greater continuity of care and the probability of an ED visit after controlling for confounders. Conclusion: Having multiple primary care providers before surgery increased the likelihood of negative outcomes following knee or hip replacement surgery compared with having a single provider. Presurgical conversations should include primary care history to improve postsurgical outcomes.","PeriodicalId":9573,"journal":{"name":"Canadian Journal of Surgery","volume":"66 5","pages":"E451-E457"},"PeriodicalIF":2.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/81/56/066E451.PMC10495165.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10587143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors attempted to address limitations of previous meta-analyses by expanding the searching strategy and exhausting more databases without placing any language restriction. They concluded that the significant benefit of lower all-cause mortality with the use of mechanical prosthesis (MP) was at the expense of higher risks of bleeding and stroke. We appreciated the authors’ efforts and contribution, and concur with the authors that most studies were subject to high risk of unmeasured confounding bias owing to unreported demographics, which lowers the quality of evidence considerably. However, we believe that the prosthetic position upon which cardiac surgeons operate is a significant contributor to not only conceptual, but also statistical heterogeneity. Besides, compared with relative risk (RR) that Kim and colleagues selected for the analysis of all-cause mortality, hazard ratio (HR) is supposed to be a more appropriate statistic, as it incorporates time into the consideration. Thus, we followed Kim and colleagues’ inclusion criteria and reconducted the meta-analysis with the introduction of a subgroup analysis based on valve position. There are 8 studies2–9 providing comparative long-term survival outcome for aortic valve replacement (AVR) between MP and bioprosthesis (BP) in dialysis patients. We showed that dialysis patients using MP for AVR was associated with significantly lower longterm all-cause mortality than those using BP (HR 0.65, 95 % confidence interval [CI] 0.51–0.83, I2 = 0 %) (Figure 1). On the other hand, the long-term overall survival was comparable between MP and BP (HR 0.91, 95 % CI 0.77–1.07, I2 = 0 %) (Figure 1) in mixed cohorts of AVR and mitral valve replacement (MVR). Regarding the bleeding events, although the use of MP was associated with a considerably higher risk in studies including mixed cohorts of AVR and MVR (incidence rate ratio [IRR] 2.37, 95% CI 1.34–4.22, I2 = 41%), we found that there was no significant difference in bleeding events between MP and BP in patients undergoing AVR (IRR 1.18, 95% CI 0.28–4.85, I2 = 0 %) (Figure 1). One plausible explanation for similar bleeding risk between MP and BP in dialysis patients undergoing AVR may reside in the lower target of international normalized ratio (INR), usual ly less than 2.5, used in this popu lation, as compared with the target of 3.0 used in MVR.28 In fact, it LETTERS • LETTRES","PeriodicalId":9573,"journal":{"name":"Canadian Journal of Surgery","volume":"66 5","pages":"E472-E473"},"PeriodicalIF":2.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/91/d4/066E472.PMC10495162.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10230474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

reports and surgeons’ assessments? Manjot Birk, Kara Sidhu, Marina Rosa Filezio, Vishwajeet Singh, Fabio Ferri-de-Barros. From the Department of Orthopaedic Surgery, University of Calgary, Calgary, Alta. Background: Cobb angle measurement is a standard method for quantification of scoliosis in patients with adolescent idiopathic scoliosis (AIS). Clinicians rely on Cobb angle measurements to guide treatment decisions. Timely and accurate diagnosis at the primary care level is required to screen patients eligible for timesensitive brace treatment, which is typically delivered in the tertiary care setting. Therefore, accurate and reliable measurement of Cobb angle at the community level is crucial. This study investigated the agreement in Cobb angle measurement between radiologist and the treating spine surgeon. Methods: A retrospective audit of radiographs for patients with AIS was performed. A random sample of 80 patients was selected and radiographic reports (Cobb angle, Risser stage and end vertebrae) by radiologists and spine surgeons were compared. To assess interrater reliability, interclass correlation coefficients (ICC) with 95% confidence intervals (CIs) were computed. Interclass correlation coefficients &lt; 0.70, 0.70–0.79, 0.80–89, and 0.9–0.99 were considered poor, fair, good and excellent reliability, respectively. All radiographs were assessed for quality. Results: The agreement of Cobb angle between spine surgeons was excellent (ICC 0.96, 95% CI 0.94 to 0.97). The agreement between spine surgeons and radiologists was poor (ICC 0.65, 95% CI 0.13 to 0.97). The ICC between spine surgeons and community radiologists and pediatric radiologists was poor (ICC 0.45, 95% CI 0.17 to 0.66) and good (ICC 0.87, 95% CI –0.46 to 0.96), respectively. However, 35 out of 80 radiographs performed did not meet the standard criteria. Risser stage was not reported in 56 of the 80 radiology reports. Interclass correlation coefficients between spine surgeons and radiologists for Risser stage was poor (ICC 0.625, 95% CI 0.325 to 0.794). For end vertebrae identification, there was absolute agreement of end vertebrae identification in 23 of the 80 scans. Conclusion: This study demonstrated a significant disagreement in Cobb angle measurement between radiologists and spine surgeons, which may negatively affect referral wait times and timely treatment for AIS. Quality improvement initiatives, such as continuing medical education, to improve Cobb angle measurement among community radiologists is required to improve scoliosis screening at the primary care level.
