Abstract
Background Surgical site infections (SSIs), the third most common nosocomial infection, endanger hospitals and patients. SSIs must be monitored continuously. This present study examined SSI incidence, risk factors, pathogens, and antibiotic sensitivity in emergency and elective or planned abdominal surgeries. Methods The Dr. S.N. Medical College General Surgery Department in Jodhpur, India, operated on 100 patients. The sample was divided into two 50-person groups. Group A includes emergency surgery patients, while Group B includes elective surgery patients. The samples were aseptically collected and processed according to microbiological methods. Data were processed with IBM SPSS Statistics for Windows, version 20 (released 2011; IBM Corp., Armonk, New York, United States). Results Out of a sample size of 100 patients, 17 individuals experienced SSIs. SSI incidence was 16.66% in male patients and 18.18% in female patients. In addition, the rate of SSIs was 26% in the emergency group and 8% in the planned group. The association was stronger among elderly individuals, diabetics (33.33% in Group A and 12.5% in Group B), and anemics with a history of smoking. The association was higher in those who underwent surgery for more than 60 minutes (34.37% in Group A and 18.8% in Group B). The incidence of SSIs was higher in emergency cases compared to elective surgeries, with rates of 26% and 8%, respectively, but was statistically insignificant. The infection rate in clean cases during planned surgery was 3.70%, while clean contaminated cases during planned surgery had a wound infection rate of approximately 13.04%. In emergency surgery, no clean case was operated on, but the SSI rate in the emergency group was 9.09%, 22.22%, and 47.36% in the clean-contaminated, contaminated, and dirty cases, respectively. In Group A, Escherichia coli was the predominant organism found in SSI wounds, while in Group B, Staphylococcus aureus was the predominant organism, accounting for 46.15% and 50% of infections, respectively. Amikacin and metronidazole exhibited the highest efficacy against E. coli, with amikacin demonstrating the highest sensitivity. Conclusion SSIs are more common in emergencies than planned procedures. Age, gender, diabetes, hypertension, smoking, and prolonged surgery are risk factors for SSIs. Effective antibiotic policy and infection control can greatly prevent SSIs.

Abstract
Background: Surgical site infections (SSI) are one of the most common hospital-acquired infections worldwide. SSI are known to increase morbidity, mortality, length of stay in hospital as well as the cost of treatment to the patients. The incidence varies from 1% to 20% among developed countries to as high as 40% in developing world. Aims: To find the incidence and risk factors, bacteriological profile, and antibiogram for SSI in General Surgery department of a tertiary care hospital in Western Rajasthan. Methods: Culture and sensitivity of wounds of all the clinically suspected cases of SSI were taken. Bacterial identification and antimicrobial susceptibility were performed according to standard CLSI guidelines. Statistical analysis was done using Microsoft Excel, SPSS 13 software. Results: Among total 609 patients, 102 were clinically suspected SSI and 88 were culture positive. Incidence of SSI was 14.45%. The most common organism was Staphylococcus aureus followed by Klebsiella pneumoniae. Most of the Gram-positive isolates were resistant to penicillin and cephalosporin antibiotics and were moderately susceptible to fluoroquinolones and aminoglycosides. Gram-negative isolates were resistant to beta-lactam and beta-lactam/beta-lactamase inhibitor combination also but were susceptible to fluoroquinolones, aminoglycosides, and carbapenems. Results: Among total 609 patients, 102 were clinically suspected SSI and 88 were culture positive. Incidence of SSI was 14.45%. The most common organism was Staphylococcus aureus followed by Klebsiella pneumoniae. Most of the Gram-positive isolates were resistant to penicillin and cephalosporin antibiotics and were moderately susceptible to fluoroquinolones and aminoglycosides. Gram-negative isolates were resistant to beta-lactam and beta-lactam/beta-lactamase inhibitor combination also but were susceptible to fluoroquinolones, aminoglycosides, and carbapenems. Conclusion: High incidence rate of SSI in our setup emphasizes the need of quality surgical care which takes into consideration all the three important factors, i.e. host, environmental, and microorganism characteristics before doing any surgery. Increasing resistance to commonly used antibiotics warrants the judicious use of antibiotics and establishment of antibiotic policy in the hospital.

Abstract
BACKGROUND Health-care-associated infection is the most frequent result of unsafe patient care worldwide, but few data are available from the developing world. We aimed to assess the epidemiology of endemic health-care-associated infection in developing countries. METHODS We searched electronic databases and reference lists of relevant papers for articles published 1995-2008. Studies containing full or partial data from developing countries related to infection prevalence or incidence-including overall health-care-associated infection and major infection sites, and their microbiological cause-were selected. We classified studies as low-quality or high-quality according to predefined criteria. Data were pooled for analysis. FINDINGS Of 271 selected articles, 220 were included in the final analysis. Limited data were retrieved from some regions and many countries were not represented. 118 (54%) studies were low quality. In general, infection frequencies reported in high-quality studies were greater than those from low-quality studies. Prevalence of health-care-associated infection (pooled prevalence in high-quality studies, 15·5 per 100 patients [95% CI 12·6-18·9]) was much higher than proportions reported from Europe and the USA. Pooled overall health-care-associated infection density in adult intensive-care units was 47·9 per 1000 patient-days (95% CI 36·7-59·1), at least three times as high as densities reported from the USA. Surgical-site infection was the leading infection in hospitals (pooled cumulative incidence 5·6 per 100 surgical procedures), strikingly higher than proportions recorded in developed countries. Gram-negative bacilli represented the most common nosocomial isolates. Apart from meticillin resistance, noted in 158 of 290 (54%) Staphylococcus aureus isolates (in eight studies), very few articles reported antimicrobial resistance. INTERPRETATION The burden of health-care-associated infection in developing countries is high. Our findings indicate a need to improve surveillance and infection-control practices.

Abstract
OBJECTIVE To determine the incidence of and risk factors for surgical-site infections (SSIs) after abdominal surgery. DESIGN A cohort study was conducted from January to June 1998. CDC criteria for SSI and the NNIS System risk index were used. SETTING A tertiary-care hospital in Peru. PATIENTS Adult patients undergoing abdominal surgery who consented were enrolled and observed until 30 days after surgery. Patients who had undergone surgery at another hospital or who died or were transferred to another hospital within 24 hours after surgery were excluded. RESULTS Four hundred sixty-eight patients were enrolled. Their mean age was 37.2 years. One hundred twenty-five patients developed SSIs, 18% of which were identified after discharge. The overall incidence rate (IR) was 26.7%. The IR was 13.9% for clean, 15.9% for clean-contaminated, 13.5% for contaminated, and 47.2% for dirty interventions. The IR was 3.6% for NNIS System risk index 0 and 60% for index 3. Risk factors for SSI on logistic regression analysis were dirty or infected wound (RR, 3.8; CI95, 1.7-8.4), drain use longer than 9 days (RR, 6.0; CI95, 2.5-12.5), and length of surgery greater than the 75th percentile (RR, 2.1; CI95, 1.0-4.4). Patients with SSI had a longer hospital stay than did non-infected patients (14.0 vs 6.1 days; p < .001). CONCLUSIONS SSI is a major problem in this hospital, which has a higher IR (especially for clean interventions) than those of developed countries. In developing countries, prevention of SSI should include active surveillance and interventions targeting modifiable risk factors.

Abstract
BACKGROUND Because patterns of infection acquired in patients undergoing operation are ever changing, it is an essential part of nosocomial infection surveillance programs to periodically document the epidemiologic features of infection in these patients. This study was conducted with the primary intention of describing the incidence and risk factors of the surgical site infection (SSI). METHODS We performed a prospective study in patients undergoing certain major operations at a 750-bed university hospital in Thailand. The National Nosocomial Infection Surveillance (NNIS) system method and criteria were used for identifying and diagnosing infection. The infection rates were benchmarked with the NNIS report by means of indirect standardization and reported in terms of standardized infection ratio. Risk factors for SSI were evaluated using the multiple logistic regression model. RESULTS From September 1998 to March 2000, the study included 4193 patients with 4437 major operations. The study identified 192 SSIs, 76 urinary catheter-related urinary tract infections, 26 central line-related bloodstream infections, and 39 instances of ventilator-associated pneumonia (VAP), yielding an infection rate of 4.3 SSIs/100 operations, 11.0 catheter-related urinary tract infections/1000 urinary catheter-days, 6.1 central line-related bloodstream infections/1000 central line-days, and 11.0 VAPs/1000 ventilator-days. When compared with data from NNIS, the standardized infection ratio of SSI, catheter-related urinary tract infection, central line-related bloodstream infection, and VAP were 2.3, 2.1, 1.1, and 0.8, respectively. The factors that significantly associated with SSI were duration of operation in minutes, American Society of Anesthesiologists (ASA) class, and degree of wound contamination. CONCLUSION All of the infection rates identified, except VAP, were higher than the average NNIS rates. The risk factors for SSI were prolonged duration of operation, poor physical status according to ASA classification, and higher degree of wound contamination.

Abstract
O presente trabalho teve como objetivo analisar o possível impacto de intervenções para reduzir a mortalidade de crianças e mães brasileiras. Através de uma combinação de métodos demográficos diretos e indiretos, avaliaram-se as tendências temporais, as variações regionais e a distribuição por causas da mortalidade de mães e crianças. Avaliou-se também a atual cobertura de programas preventivos. Com base nesses parâmetros, assim como em uma revisão da literatura sobre a efetividade das intervenções disponíveis, foram obtidas estimativas do impacto potencial de cada tipo de intervenção. A mortalidade em crianças vem sendo reduzida, mas os níveis atuais ainda são elevados e há importantes desigualdades regionais, com o Nordeste e Norte apresentando os mais altos índices. Devido à predominância de causas perinatais na mortalidade de crianças brasileiras, as medidas de maior potencial são aumentos na qualidade e cobertura do atendimento pré-natal e ao parto, seguidos pelo manejo integrado de doenças infecciosas e de problemas nutricionais. Melhorias no pré-natal e parto também contribuiriam para reduzir a mortalidade materna. É importante, ainda, garantir a sustentabilidade dos avanços já alcançados em áreas como as imunizações, a terapia de reidratação oral e o planejamento familiar, assim como investir intensamente na redução das importantes desigualdades regionais.
