Despite total shoulder arthroplasty (TSA) and reverse TSA (rTSA) being fundamentally different procedures, and indicated in different pathologies (rTSA for rotator cuff deficiency [RCD] and proximal humeral fractures [PHFx] and anatomic TSA [aTSA] for glenohumeral osteoarthritis [GHOA]), they have the same Current Procedural Terminology (CPT) code (23472). This paper's aim is to investigate differences in operative time and work-related value units (wRVUs) per hour among these pathologies, and ultimately determine if there is a need to assign separate CPTs for aTSA and rTSA. A retrospective cohort of data from the American College of Surgeons–National Surgical Quality Improvement Program was collected, all patients who underwent aTSA or rTSA (CPT: 23472) between the years of 2006 and 2019 for diagnoses of GHOA, RCD, and PHFx were included. Data collected included patient age, body mass index, operative time, and wRVUs per hour. Compared to GHOA (reference group), the average operative time for the RCD cohort was 12.242 minutes shorter (P <.001), while the wRVUs were higher by 1.627 (P <.001). The average operative time for rTSAs in the PHFx cohort were 17.615 minutes longer (P <.001), while the wRVUs were lower by 2.205 (P <.001). The average operative time for rTSAs for both RCDs and PHFx were longer than that for aTSAs for GHOA. Additionally, wRVUs were lower for rTSAs for RCD and PHFx compared to aTSAs for GHOA. This elucidates inconsistency in reimbursement structure for the procedures, which should be revisited. [ABSTRACT FROM AUTHOR]

Background: Influenza is a major cause of morbidity and mortality in Africa. However, a lack of epidemiological data remains for this pathology, and the performances of the influenza-like illness (ILI) case definitions used for sentinel surveillance have never been evaluated in Senegal. This study aimed to i) assess the performance of three different ILI case definitions, adopted by the WHO, USA-CDC (CDC) and European-CDC (ECDC) and ii) identify clinical factors associated with a positive diagnosis for Influenza in order to develop an algorithm fitted for the Senegalese context.Methods: All 657 patients with a febrile pathological episode (FPE) between January 2013 and December 2016 were followed in a cohort study in two rural villages in Senegal, accounting for 1653 FPE observations with nasopharyngeal sampling and influenza virus screening by rRT-PCR. For each FPE, general characteristics and clinical signs presented by patients were collected. Sensitivity, Specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) for the three ILI case definitions were assessed using PCR result as the reference test. Associations between clinical signs and influenza infection were analyzed using logistic regression with generalized estimating equations. Sore throat, arthralgia or myalgia were missing for children under 5 years.Results: WHO, CDC and ECDC case definitions had similar sensitivity (81.0%; 95%CI: 77.0-85.0) and NPV (91.0%; 95%CI: 89.0-93.1) while the WHO and CDC ILI case definitions had the highest specificity (52.0%; 95%CI: 49.1-54.5) and PPV (32.0%; 95%CI: 30.0-35.0). These performances varied by age groups. In children < 5 years, the significant predictors of influenza virus infection were cough and nasal discharge. In patients from 5 years, cough, nasal discharge, sore throat and asthenia grade 3 best predicted influenza infection. The addition of "nasal discharge" as a symptom to the WHO case definition decreased sensitivity but increased specificity, particularly in the pediatric population.Conclusion: In summary, all three definitions studies (WHO, ECDC & CDC) have similar performance, even by age group. The revised WHO ILI definition could be chosen for surveillance purposes for its simplicity. Symptomatic predictors of influenza virus infection vary according the age group. [ABSTRACT FROM AUTHOR]
