BACKGROUND: Nosocomial TB transmission adversely affects inpatients and healthcare workers (HCWs). HCWs have a higher risk of tuberculosis and MDR-TB compared to the general population. Nosocomial TB outbreaks have occurred among patients with HIV/AIDS. Hospitals need to examine TB infection control measures in order to address this growing concern.

OBJECTIVE: This study aimed to evaluate the TB infection control strategies in the adult service wards of the Philippine General Hospital (PGH).

METHODS: This descriptive study was conducted on adult inpatients with bacteriologically-confirmed PTB admitted in April-August 2016. A data collection tool based on Center for Disease Control (CDC) guidelines was utilized for chart review. Baseline characteristics, diagnosis, treatment, and isolation intervals were obtained and compared between areas. In-hospital TB infection control practices were reviewed using the CDC TB Risk Assessment Worksheet with data from the TB-DOTS, UP Health Service, PGH Hospital Infection Control Unit, and PGH Department of Laboratories.

RESULTS: Of the 95 patients with bacteriologically-confirmed PTB, data from 72 medical records were available and included in the analysis. Majority were Medicine patients (55.6%) with a diagnosis of pneumonia (52.8%). Only 61.1% were PTB suspects on admission. The mean diagnosis interval was 5.82 days±5.473, the mean treatment interval was 0.77 days±2.941, and the mean isolation interval was 8.23 days±6.372. Only 41.7% were successfully isolated. The most common reasons for isolation failure/delay were lack of vacancy (ER, Medicine wards) and lack of isolation room (Surgical wards). Treatment initiation rate was 66.7% while TB-DOTS inpatient referral rate was 55.6%. The hospital is classified as having potential ongoing transmission of PTB.

CONCLUSION: In this study, TB treatment was promptly started but there were delays in diagnosis and isolation. Gaps included 1) lack of recognition of a PTB case, 2) limited isolation rooms, and 3) inadequate utilization of TB-DOTS. TB infection control measures need to be strengthened in order to prevent nosocomial transmission of PTB.

BACKGROUND: While hand hygiene is recognized as the cornerstone for reducing risk for nosocomial infections, compliance in our institution remains low. Previously identified barriers include poor access to hand hygiene products, lack of reminders, and poor knowledge on indications.

METHODS: At the medical wards and ICU of a tertiary hospital, a group of medical students, residents, and nurses was exposed to interventions addressing the identified barriers. Alcohol handrub was provided at each bedside, visual reminders were placed at critical locations, and commonly missed opportunities were reinforced at the start of the study. Hand hygiene compliance was covertly evaluated after two weeks and compared against that of an unexposed group.

RESULTS: 664 and 727 hand hygiene opportunities were observed in the unexposed and exposed groups, respectively. Compliance was higher in the exposed group (32.60% vs. 16.26%, p <0.05), which by subset analysis was consistent for the different healthcare worker designations and locations evaluated. Nurses had the highest compliance rate in both groups.

CONCLUSIONS: These results suggest the efficacy of the employed interventions in improving hand hygiene compliance in this setting. Hand hygiene opportunities identified to be most frequently missed in this observation can guide future intervention efforts in our institution.

The study retrospectively reviewed 1,029 general surgery operations performed from September 1, 1991 to May 31, 1993 to find out the association between the occurrence of surgical site infection (SSI) and the Centers for Disease Control-National Nosocomial Infection Surveillance (CDC-AWS) surgical patient risk index scores. The index assigned 1 point for each of 3 risk factors: 1) American Society of Anesthesiologists (ASA) preoperative assessment class 3, 4 or 5; 2) an operational classified as either contaminated or dirty-infected; 3) an operation with a duration longer than a specified increased with increasing contamination (p=0.000) as well as increasing index scores (p=0.000). Looking at operations within the same category of contamination, SSI rates also increased with increasing scores among clean operations (p=0.944), clean-contaminated operations (p=0.000), contaminated operations (p=0.559), and dirty operations. SSI rates in this hospital series were compared to the 44-hospital CDC-NNIS report.

PURPOSE: This study was conducted to investigate factors influencing influenza infection control compliance in nurses, including knowledge about, and awareness of infection control. METHODS: The study participants were 168 nurses who worked at a hospital in J Province. Data were collected by self-reported questionnaires in April 2015. Collected data were analyzed using SPSS/WIN 20.0 program. RESULTS: Mean score for knowledge about droplet precaution was 12.16 out of 16.00. Mean score for awareness about droplet precautions was 3.49 out of 4.00, and mean score for droplet precaution compliance was 3.33 out of 4.00. There was a positive correlation among knowledge, awareness and compliance (p<.001). Awareness, knowledge and experience of seasonal influenza education were the significant factors affecting the level of compliance (37.8%). CONCLUSION: Study results indicate that an educational program focusing on strategies to change nurses' awareness would be effective in improving infection control of respiratory virus and droplet precaution compliance in hospitals.

The most frequent cause of mortality in neonates is infections which include sepsis, meningitis, pneumonia, diarrhea and tetanus. Approximately 1.6 million deaths due to neonatal infections occur annually in developing countries. The causes of sepsis vary from one geographic area to another. Thus, it is important to create a database for the Philippines regarding the etiologies of neonatal sepsis. Objectives: The study was undertaken to determine the most common bacterial pathogens of neonatal sepsis in the Philippines and the antibiotic sensitivity patterns of these pathogens. Methods: A multicenter surveillance and chart review was conducted in five hospital sites for a period of six months- from July to December 2006. All neonates less than or equal to 28 days who had positive cultures from a sterile site and or had fulfilled the SIRS criteria as defined by the International Pediatric Sepsis Consensus Conference in the presence of suspected or proven infection were included in the study. Results: A total of 289 neonates fulfilled the criteria of sepsis. More than 61% of the patients had early onset neonatal sepsis. The most common site of infection was the lungs, (57%), followed by sepsis without an obvious site of infection (35%). In 50% of patients, an organism was identified; gram-negative bacteria were the dominant bacteria found (Pseudomonas, Burkholderia, Klebsiella) which comprised 94% of the bacteria isolated. Resistance patterns varied among the different urban study centers. The Pseudomonas and Burkholderia isolates from the Philippine General Hospital (PGH) were sensitive to ceftazidime. All Klebsiella isolates from St. Louis University (SLU) were resistant to third generation cephalosporins. In contrast, Klebsiella isolates from PGH and Davao were sensitive to third generation cephalosporins but resistant to piperacillin-tazobactam. The overall mortality rate was 11%. Ampicillin and an aminoglycoside were the most common regimens used but were only successful in less than 50% of cases. Conclusion: Gram-negative organisms comprised the majority of the neonatal infections, with Pseudomonas and Burkholderia being the most prevalent. Resistance patterns differed among the different centers. Continuing surveillance of infections is still needed in order choose the most appropriate empiric therapy for each center.

Distribution of Sparganum mansoni in 7 species of terrestrial snakes in Wonju City was surveyed. All kinds of snakes were found to be served as intermediate hosts of this larval worm except Elaphe schrenkii which has already been recorded as important host. Authors believe that Zamenis spinalis was firstly recorded as intermediate host of Sparganum mansoni in Korea. Some aspects of infection status, host-parasite relations and sources of human infection were briefly discussed.

PURPOSE: This study was to provide baseline data about nurses' Influenza A (H1N1) knowledge, awareness, andpractice of infection control and to identify the significant factor affecting the level of practice. METHODS: The subjects of this study were 144 nurses who worked at Influenza A (H1N1) regional base Hospital in D city. Data were collected by self-reported questionnaires during September 2009. The collected data were analyzed using SPSS/WIN 12.0 program. RESULTS: The knowledge of Influenza A (H1N1) was statistically different according to age, unit, career and experience of seasonal influenza vaccination during the last year. The awareness of infection control was statistically different according to age, career, experience of seasonal influenza vaccination for last year and intention to get seasonal influenza vaccination for this year. The practice of infection control was statistically different according to unit, experience of seasonal influenza vaccination for last year, intention to get seasonal influenza vaccination for this year and intention to get Influenza A (H1N1) vaccination for this year. There was positive correlation among knowledge, awareness and practice (p < .05). Awareness was the significant factor affecting the level of practice. CONCLUSION: An educational program focusing on strategy to change nurse's awareness can be effective for infection control of Influenza A (H1N1) in regional base hospitals.

When evaluating patients presenting with progressive unilateral hearing loss without a history of trauma or infection, it is important consider the clinical correlation of physical examination findings, imaging and audiograms. It is crucial that all findings are correctly reviewed and analyzed to provide an accurate assessment and appropriate management for the patient.

Percent body surface area (BSA) burned and patient age are useful early prognostic indicators in burned patients, but have limited value in predicting which patients in a given cohort are likely to die. The objective of this study was to come up with additional variables of burn injury which could better predict patient outcome. Variables such as burn demographic data (age, sex, percent body surface area burned, type of burn, etc.) laboratory data on admission (CBC, Urinalysis, ABG, Serum electrolytes) and presence of infection within the first ten days of burn injury were subjected to analysis using correlation matrix. Variables with significant correlation with mortality were then subjected to second level analysis. Differences of values for the surviving and non-surviving groups were then compared. Compared to survivors, non-survivors had significantly larger burns (58.08% BSA + 12.45 vs. 20.92% BSA+10.45; P0.01), higher values of hemoglobin and WBC counts (68.83 g/dl+15.96 vs 132.21 g/dl+ 10.85 and 23.75+4.5222 vs. 13.7728+6.4439; both p values of 0.01). Incidence of wound infection was likewise greater with the non-survivors. (58% vs. 15%; p0.01). Multiple regression analyses revealed that patients burn (%BSA), hemoglobin, hematocrit, WBC count and incidence of wound infection can be used as variables in the computation for burn severity scores.
