Health Care Associated Infection and Trend of Antimicrobial Resistance in Tertiary Care Hospital -A Study in Low Income Setting

Background Antimicrobial resistance (AMR) and healthcare-associated infections (HAIs) are among the most serious public health problems and overall estimate indicates that at any point, over 1.4 million people are suffering from health care associated infection globally. According to the WHO report, the frequency of nosocomial infection is 10% in South East Asia where as 7% in developed countries. The increasing trend of AMR in pathogenic bacteria leads to complication to treat HAIs and failure in treatment and rise in mortality. Objective The study was conducted with the objective of to explore the incidence of different types of HAIs and AMR pattern in the patients admitted in a tertiary care hospital. Method The cross-sectional study was conducted at the tertiary care hospital and the patient who are one year or older and admitted for more than 48 hours were included in this study. The criteria for classification of HAIs were adapted from Centers for Disease Control. All the samples were collected then antibiotic sensitivity testing was conducted according to CLSI standards. Data were collected using a structured data collection form. Data were entered in EpiData software and analyzed using SPSS version 22. Result Among 2326 patients, female was slightly higher than male patients, where 77 (3.3%) patients experienced at least one episode of HAIs. The surgical site infection (71.42%) is the most common infection followed by Catheter Associated Urinary Tract Infection (18.18%) and Health Care Associated Pneumonia (6.49%). Mean hospitalization days is higher with HAI (14.5 days) compared to non-HAI (6.6 days). Out of 909 specimens, urine, sputum and blood were higher in numbers, where 217 bacterial isolates were isolated with Escherichia coli (83 isolates) was the most common bacteria. It is found that Escherichia coli bacterial isolates were resistance to most common antibiotics. Conclusion The study concludes that surgical site infection is the most common healthcareassociated infection and Escherichia coli is the most common bacteria responsible for HAIs. Further, surgical site infection being the most common infection, there is an urgent need to take effective infection prevention and control prevention.

Surgical outcomes of microincision vitrectomy surgery in eyes with retinal detachment secondary to retinopathy of prematurity in Indian population

Purpose:

To analyze and report outcomes of microincision vitrectomy surgery (MIVS) for Stage 4 and 5 retinopathy of prematurity (ROP).

Methods:

Medical records of 202 eyes of 129 premature children undergoing MIVS for Stage 4/Stage 5 ROP between January 2012 and April 2015 were evaluated. The primary outcome measure was the proportion of eyes with anatomical success (defined as attached retina at the posterior pole at last follow-up). Complications associated with MIVS were noted and analysis of risk factors associated with poor anatomical outcome was also done using logistic regression.

Results:

Mean age of presentation of babies with Stage 4 ROP (2.9 ± 1.75 months) was lower than those with stage 5 disease (5.62 ± 2.55 months) (P < 0.005). One hundred seventeen eyes (56% or 58%) had Stage 5, 38 (19%) had Stage 4a, and 47 (23%) Stage 4b. Ninety-four eyes (47%) had received prior treatment (laser and/or anti-vascular endothelial growth factors [VEGF]). Lens-sparing vitrectomy (LSV) was performed in 58 (29%) eyes while lensectomy with vitrectomy (LV) was performed in 144 (71%) eyes. At a mean follow-up of 32.5 weeks, 102 (50.5%) eyes achieved anatomical success, including 74% eyes in Stage 4a and 4b and 33% in Stage 5. Complications included intraoperative break formation (19%), postoperative vitreous hemorrhage (28%), raised intraocular pressure (12.7%), and cataract progression (2.4%). Factors significantly associated with favorable anatomical outcome were Stage 4 disease (vs. Stage 5) (odds ratio [OR] 5.8; confidence interval [CI] =2.6–13.8, P < 0.005), prior treatment (laser ± anti-VEGF) (OR 2.5; CI 1.4–4.7, P < 0.005) surgery with 25G MIVS (vs. 23G) (OR: 1.7; CI = 0.98–3.00, P = 0.05) and LSV (vs. LV) (OR 7; CI = 3.4–14.6, P < 0.005). Retinal break was significantly associated with poor anatomical outcome (OR 0.21; CI = 0.09–0.5, P < 0.005).

Conclusion:

MIVS along with wide angle viewing systems allow surgeons to effectively manage ROP surgeries while at the same time reducing complication rate in these eyes which have complex pathoanatomy and otherwise grim prognosis.
