Objective.To evaluate whether surgical site infection (SSI) rates decrease in surgical departments as a result of performing active SSI surveillance.Design.Retrospective multiple logistic regression analyses.Setting.A group of 130 surgical departments of German hospitals participating in the Krankenhaus Infektions Surveillance System (KISS).Methods.Data for 19 categories of operative procedures performed between January 1997 and June 2004 were included (119,114 operations). Active SSI surveillance was performed according to National Nosocomial Infections Surveillance system (NNIS) methods and definitions. Departments' SSI rates were calculated individually for each year of surveillance and for each operative procedure category, taking into account when the individual departments had begun their surveillance activities. Multiple logistic regression analyses on a single operation basis were carried out with stepwise variable selection to predict outcomes for patients with SSI. The variables included were as follows: the department's year of participation, NNIS risk index variables, patients' age and sex, and the hospitals' structural characteristics, such as yearly operation frequency, number of beds, and academic status.Results.For 14 of 19 operative procedure categories analyzed, there was a tendency toward lower SSI rates that was associated with increasing duration of SSI surveillance. In multiple logistic regression analyses of pooled data for all operative procedures, the departments' participation in the surveillance system was a significant independent protective factor. Compared with the surveillance year 1, the SSI risk decreased in year 2 (odds ratio, 0.84; 95% confidence interval, 0.77-0.93) and in year 3 (odds ratio, 0.75; 95% confidence interval, 0.68-0.82), and there was no change in year 4.Conclusion.The SSI incidence was reduced by one quarter as a result of the surveillance-induced infection control efforts, which indicates the usefulness of a voluntary surveillance system.

Introduction: Surgical site infection (SSI) following hydrocelectomy is relatively uncommon, but it is one of the main post-operative problems. We aimed to describe the prevalence of SSI following hydrocelectomy among adult patients, and to assess predisposing risk factors for infection. Methodology: This retrospective cohort study was carried out at a university hospital and included hydrocelectomies performed between January 2007 and December 2014. Diagnosis of SSI was performed according to the Center for Diseases Control (CDC) guidelines. Multivariable logistic regression analysis was used to identify independent risk factors. Results: A total of 196 patients were included in the analysis. Overall, 30 patients were diagnosed with SSI (15.3%) and of these, 63.3% (19/30) were classified as having superficial SSI, while 36.7% (11/30) had deep SSI. The main signs and symptoms of infection were the presence of surgical wound secretion (70%) and inflammatory superficial signs such as hyperemia, edema and pain (60%). Among the 53 patients presenting chronic smoking habits, 26.4% (14⁄53) developed SSI, which was associated with a higher risk for SSI (odds ratio [OR] = 2.84, 95% confidence interval [CI] = 1.27 to 6.35, p < 0.01) in the univariate analysis. In the adjusted multivariable analysis, smoking habits were also statistically associated with SSI after hydrocelectomy (odds ratio [OR] = 2.84, 95% confidence interval [CI] = 1.30 to 6.24, p = 0.01). No pre-, intra-, or post-operative variable analyzed showed an independent association to SSI following hydrocelectomy. Conclusions: Smoking was the only independent modifiable risk factor for SSI in the multivariate analysis.

AbstractOsteoarthritis is the main cause for total knee arthroplasty (TKA), followed by rheumatoid arthritis. Previous studies have reported conflicting results concerning the risk of surgical site infection after TKA for rheumatoid arthritis and osteoarthritis patients. Thus, this study aimed to examine whether rheumatoid arthritis patients had a higher risk of acute surgical site infection after TKA compared to osteoarthritis patients. We conducted a retrospective cohort study using Taiwan’s National Health Insurance Research Database of the whole population from 2012 to 2015, and collected the medical records of osteoarthritis patients or rheumatoid arthritis patients who underwent TKA. To evaluate the risk of acute surgical site infection in rheumatoid arthritis patients, propensity score matching was implemented for osteoarthritis patients. Acute surgical site infection was observed in 2.58% of TKA cases in rheumatoid arthritis patients and 2.66% of TKA cases in osteoarthritis patients. Rheumatoid arthritis and osteoarthritis patients had comparable risk for 90-day (odds ratio = 0.81, 95% confidence interval: 0.371–1.768) and 1-year (odds ratio = 0.463, 95% confidence interval: 0.121–1.766) surgical site infection. In conclusion, patients with rheumatoid arthritis were not at higher risk of acute surgical site infection after TKA compared to osteoarthritis patients. The current treatment strategy for patients with RA is safe and appropriate if they require TKA.

Background: The G allele of NOTCH4 rs422951 is protective against demyelinating disease in Japanese. Objectives: The purpose of this study was to assess the relation of the G allele to neuromyelitis optica (NMO)/NMO spectrum disorder (NMOSD) and multiple sclerosis (MS) and the interaction between the G allele and HLA-DRB1 alleles, and to clarify any association of the G allele with clinical features. Methods: DNA sequencing was used to genotype 106 NMO/NMOSD patients, 118 MS patients and 152 healthy controls (HCs) for rs422951. Results: G allele frequency in MS patients, but not that in NMO/NMOSD patients, was lower than that in HCs (8.9% vs 21.7%, p<0.0001, odds ratio (OR)=0.35). HLA-DRB1*0405 was positively associated with MS (OR=2.22, pcorr=0.0380) while DRB1*0901 was negatively associated (OR=0.32, pcorr =0.0114). Logistic regression analyses revealed that, after adjusting for gender and either HLA-DRB1*0405 or DRB1*0901, rs422951 was associated with MS in the dominant model (OR=0.37, 95% confidence interval (CI)= 0.20–0.66, p=0.0012). Haplotype analyses identified two susceptible and three resistant haplotypes formed from rs422951 and either HLA-DRB1*0405 or DRB1*0901. There were no statistically significant differences in clinical features between G allele carriers and non-G allele carriers. Conclusion: This NOTCH4 missense mutation decreased the risk for developing MS in Japanese, but did not affect clinical features of those who had already developed the disease.

Abstract Objective The study sought to evaluate if peer input on outpatient cases impacted diagnostic confidence. Materials and Methods This randomized trial of a peer input intervention occurred among 28 clinicians with case-level randomization. Encounters with diagnostic uncertainty were entered onto a digital platform to collect input from ≥5 clinicians. The primary outcome was diagnostic confidence. We used mixed-effects logistic regression analyses to assess for intervention impact on diagnostic confidence. Results Among the 509 cases (255 control; 254 intervention), the intervention did not impact confidence (odds ratio [OR], 1.46; 95% confidence interval [CI], 0.999-2.12), but after adjusting for clinician and case traits, the intervention was associated with higher confidence (OR, 1.53; 95% CI, 1.01-2.32). The intervention impact was greater in cases with high uncertainty (OR, 3.23; 95% CI, 1.09- 9.52). Conclusions Peer input increased diagnostic confidence primarily in high-uncertainty cases, consistent with findings that clinicians desire input primarily in cases with continued uncertainty.

Abstract Although restorative proctocolectomy is recognized as a standard procedure for ulcerative colitis, infectious complications after surgery cannot be disregarded. The aim of this study was to define predictors of surgical site infection (SSI) in urgent/emergent surgery for ulcerative colitis. We performed prospective SSI surveillance for 90 consecutive patients. Possible risk factors were analyzed by logistic regression analyses. Incidences of incisional SSI (i-SSI) and organ/space SSI were 31.1% and 6.9%, respectively, and increased significantly with higher wound class (P &lt; 0.01). Multivariate analysis showed wound class ≥3 as an independent risk factor for i-SSI. In univariate analysis, although the mucous fistula procedure was a risk factor for i-SSI (odds ratio, 3.45; P &lt; 0.01), Hartmann procedure also represented a risk factor for o-SSI (odds ratio, 12.8; P &lt; 0.01). Urgent restorative proctocolectomy for patients without high wound class and emergent total colectomy with mucous fistula for patients with high wound class appear to represent feasible options.

Abstract Background: The aim of this study was to explore whether electronically retrieved laboratory data can predict mortality in internal medicine departments in a regional hospital. Methods: All 10 308 patients hospitalized in internal medicine departments over a 1-year period were included in the cohort. Nearly all patients had a complete blood count and basic clinical chemistries on admission. We used logistic regression analysis to predict the 573 deaths (5.6%), including all variables that added significantly to the model. Results: Eight laboratory variables and age significantly and independently contributed to a logistic regression model (area under the ROC curve, 88.7%). The odds ratio for the final model per quartile of risk was 6.44 (95% confidence interval, 5.42–7.64), whereas for age alone, the odds ratio per quartile was 2.01 (95% confidence interval, 1.84–2.19). Conclusions: A logistic regression model including only age and electronically retrieved laboratory data highly predicted mortality in internal medicine departments in a regional hospital, suggesting that age and routine admission laboratory tests might be used to ensure a fair comparison when using mortality monitoring for hospital quality control.

<p>Introducción: La infección de sitio quirúrgico (ISQ) es la infección intrahospitalaria más frecuente en los pacientes quirúrgicos con una incidencia entre 5-30%. Objetivos: Identificar los factores de riesgo para ISQ en cirugía colónica en nuestra población. Los objetivos secundarios son determinar la incidencia y tipo de ISQ, así como la incidencia de dehiscencia de anastomosis (DA). Materiales y métodos: Estudio de casos-controles de pacientes intervenidos de colectomía entre 2010-2014 en el Hospital Privado Universitario de Córdoba y Hospital Raúl Ferreyra. Se incluyeron las intervenciones convencionales y laparoscópicas, con seguimiento de 30 días, pacientes entre 20 y 85 años y con ASA I-III. Se excluyeron las cirugías de urgencia y las resecciones recto-anales. Se definió ISQ a aquella que ocurre dentro de 30 días. Resultados: Se incluyeron 238 pacientes. Se diagnosticó ISQ en 27,7% (n=66) de los pacientes de los cuales 12,2% fue superficial, 4,6% profunda y 10,9% de órgano/espacio. El análisis multivariado demostró que la ISQ se asocia con sexo masculino (odds ratio [OR] 3,15; IC95%:1,43-6,92; p=0,004), quimioterapia neoadyuvante (OR 6,72; IC95%:1,48-30,93; p=0,01), conversión (OR 3,32; IC95%:1,13-9,77; p=0,02), reintervención dentro de 30 días postquirúrgicos (OR 12,34; IC95%:2,65-57,37, p=0,001) y DA (OR 12,83; IC95%:2,97- 55,5; p=0,001). La DA presenta una incidencia del 9,6%, de los cuales el 91% presentó ISQ y todas fueron de órgano/espacio. Conclusión: Sexo masculino, quimioterapia neoadyuvante, conversión, reintervención dentro de 30 días postquirúrgicos y DA son factores de riesgo para ISQ en nuestra población. Estos resultados deben ser considerados para implementar medidas preventivas para ISQ.</p>

Low Renin Hypertension

Abstract Background: Medical treatment with mineralocorticoid receptor antagonists (MRAs) is preferred for patients with primary aldosteronism (PA) who are not surgical candidates. Adequate mineralocorticoid receptor blockade, as suggested by renin elevation above suppression levels, has been associated with lower rates of cardiovascular and renal complications as compared with PA with sustained renin suppression. Objectives: To assess the timeline and rates of achieving target renin levels in patients with PA and low renin hypertension treated with MRAs. Patients and Methods: We conducted a retrospective cohort study of adult patients with hypertension who were treated with MRAs in an academic center between 2003-2019. Of these, we included patients who had suppressed renin at baseline, and repeated renin measurement(s) during MRAs therapy. Renin suppression was defined as plasma renin activity (PRA) 1.0 ng/mL/h or direct renin concentration (DRC) 8.0 pg/mL. We excluded patients with adrenal cancer, end-stage renal disease, exogenous glucocorticoids, and critically ill. Mann-Whitney test, Wilcoxon signed rank test, Chi-Square test and multiple logistic regression analysis were employed, as appropriate. Results: So far, 89 patients (45 men), median age 56 (range, 19-84), have been included. Of these, 46% had confirmed PA; 25% had positive PA screening, but no confirmatory tests; and 29% had other forms of low-renin hypertension. On average, patients were on 2.9 1.6 antihypertensive agents; 62% of patients were prescribed beta blockers, and 38% were on K+ supplements. Overall, renin (PRA in 69 cases, and DRC in 20 cases) increased after MRA treatment (from 0.40 [0.10, 0.60] ng/mL/h to 1.10 [0.60, 2.23] ng/mL/h; and from 2.1 [2.1, 3.7] pg/mL to 5.7 [2.9, 16.7] pg/mL, respectively, p&lt;0.0001 for both). The cumulative proportions of patients in whom renin reached target levels during MRA treatment were: 25% at 2 weeks; 38.9% at 1 month; 34.2% at 3 months; 39.5% at 6 months; and 47.2% at 1 year. Age, sex, race, blood pressure, use of beta blockers, renal function, serum K+ and aldosterone concentrations were similar between patients with target vs. suppressed renin. Multiple logistic regression analysis suggested that after adjusting for age and sex, higher MRA dose and higher BMI were associated with higher likelihood of achieving target renin during MRA therapy (odds ratio (95%CI): 1.021 (1.001-1.041) and 1.097 (1.008-1.193), respectively, p&lt;0.05 for both); conversely, beta blockers use tended to be less often associated with target renin (odds ratio, 0.37 (0.13-1.008), p=0.052). Conclusion: Although raising renin above suppression levels is important for reducing the cardiovascular risk associated with PA, this goal is achieved in less than half of patients, even after one year of treatment with MRAs, in an academic setting. Strategies for optimizing PA treatment are critically needed.

ObjectiveTo verify the validity of a semiautomated surgical site infection (SSI) surveillance system using electronic screening algorithms in 38 categories of surgery.DesignA cohort study for validation of semiautomated SSI surveillance system using screening algorithms.SettingA 1,989-bed tertiary-care referral center in Seoul, Republic of Korea.MethodsA dataset of 40,516 surgical procedures in 38 categories stored in the conventional SSI surveillance registry at the Samsung Medical Center between January 2013 and December 2014 was used as the reference standard. In the semiautomated surveillance system, electronic screening algorithms flagged cases meeting at least 1 of 3 criteria: antibiotic prescription, microbial culture, and infectious disease consultation. Flagged cases were audited by infection preventionists. Analyses of sensitivity, specificity, and positive predictive value (PPV) were conducted for the semiautomated surveillance system, and its effect on reducing the workload for chart review was evaluated.ResultsA total of 575 SSI events (1·42%) were identified by conventional SSI surveillance. The sensitivity of the semiautomated SSI surveillance was 96·7%, and the PPV of the screening algorithms alone was 4·1%. Semiautomated SSI surveillance reduced the chart review workload of the infection preventionists from 1,283 to 482 person hours per year (a 62·4% decrease).ConclusionsCompared to conventional surveillance, semiautomated surveillance using electronic screening algorithms followed by chart review of selected cases can provide high-validity surveillance results and can significantly reduce the workload of infection preventionists.
