BACKGROUND: The outcome indicator of nosocomial infection (NI) in the intensive care unit (ICU) is used to benchmark the quality of patient care in Malaysia. We conducted a three-year prospective study on the incidences of ventilator-associated pneumonia (VAP), risk factors, and patterns of the microorganisms isolated in three ICUs.
METHODOLOGY: A follow-up in prospective cohort surveillance was conducted on patients admitted to an adult medical-surgical ICU of a university hospital and two governmental hospitals in Malaysia from October 2003 to December 2006. VAP was detected using CDC criteria which included clinical manifestation and confirmed endotracheal secretion culture results.
RESULTS: In total, 215 patients (2,306 patient-days) were enrolled into the study. The incidence of ICU-acquired device-related NI was 29.3 % (n = 63). The device-related VAP infection rate was 27.0 % (n = 58), with a mechanical ventilator utilization rate of 88.7%. The death rate due to all ICU-acquired NI including sepsis was 6.5%. The most common causative pathogen was Klebsiella pneumoniae (n = 27). Multivariate analysis using Cox regression showed that the risk factors identified were aspiration pneumonia (HR = 4.09; 95% CI = 1.24, 13.51; P = 0.021), cancer (HR = 2.51; 95% CI = 1.27, 4.97; P = 0.008), leucocytosis (HR=3.43; 95% CI= 1.60, 7.37; P=0.002) and duration of mechanical ventilation (HR=1.04; 95% CI = 1.00, 1.08; P = 0.030). Age, gender and race were not identified as risk factors in the multivariable analysis performed.
CONCLUSION: The incidence of VAP was comparable to that found in the National Nosocomial Infection Surveillance (NNIS) System report of June 1998. The incidence of VAP was considered high for the three hospitals studied.

Fulltext Varicella in children with haematological malignancy--outcome of treatment and prevention

Ho CM, Khuzaiah R, Yasmin AM

Med J Malaysia, 1994 Mar;49(1):29-35.
PMID: 8057987

Primary varicella-zoster virus infection in children with haematological malignancy is a life threatening disease. In one year, there were 10 cases of varicella and 2 cases of zoster among these children as well as 5 mothers who were accompanying their children who developed varicella in the oncology ward. Two children died of fulminating disease despite aggressive antiviral and supportive treatment. Acyclovir can be used in treatment and prophylaxis in exposed susceptible children. Varicella -zoster immune globulin is not available in this country. Vaccination with live virus has been shown to be protective in immunocompromised children and needs consideration.

PMID: 19901898

Acinetobacter spp. is a known nosocomial pathogen causing a wide range of clinical diseases mainly pneumonia, wound infections and blood stream infections (BSI). A cross sectional descriptive study was performed to determine the prevalence of Acinetobacter infection in Hospital Universiti Sains Malaysia, Kelantan (HUSM). The risk factors of Acinetobacter BSI were determined by 1:1 case control analytical study, involving fifty-eight confirmed cases of Acinetobacter BSI patients compared to the cases caused by Gram-negative bacteria. The prevalence of Acinetobacter BSI in the HUSM was 6.11% (95% CI 4.88-7.53%). The attack rate of Acinetobacter BSI was 2.77 episodes per 1000 hospital admissions. Acinetobacter BSI patients were mostly located in intensive care unit and had a longer intensive care unit stay. In univariate analysis, the risk factors for Acinetobacter BSI include prior exposure to antimicrobial agents such as penicillins, aminoglycosides and cephalosporins, mechanical ventilation, presence of nasogastric tube, arterial catheter and urinary catheter. In multivariate analysis, the independent risk factors for Acinetobacter BSI were prior treatment with cephalosporins (OR 3.836 95% CI 1.657-8.881 p=0.002) and mechanical ventilation (OR 3.164 95% CI 1.353-7.397 p=0.008). This study revealed that rational use of antimicrobial agents is of paramount importance to control Acinetobacter BSI.

PMID: 11771082

CU-acquired nosocomial infection (NI) remains one of the major causes of ICU mortality. This study presents the incidence of ICU-acquired nosocomial infection in ICU HUKM for the years 1998 and 1999, as part of the ongoing ICU-acquired nosocomial infection surveillance program. The overall incidence was 23%. The main types of NI was lower respiratory tract infection (15.3%), primary bacteraemia (8.1%), ventilator associated pneumonia (5.4%), urinary tract infection (2.0%), skin infection (1.6%) central venous catheter sepsis (1.2%) and surgical skin infection (0.8%). The overall culture positive nosocomial infection rate was only 12.1%, majority from the lungs (12.6%), blood (7.3%), skin swabs (2.0%), and urine (1.6%). The main gram-negative organism cultured was Acinetobacter sp. (19%) and Staph. aureus (8.5%) was the gram-positive organism. The overall ICU mortality rate was 27.5% of which 60.9% of patients who died were attributed directly to sepsis.

Fulltext The clinical picture of neonatal infection with Pantoea species

Van Rostenberghe H, Noraida R, Wan Pauzi WI, Habsah H, Zeehaida M, Rosliza AR, et al.

Jpn J Infect Dis, 2006 Apr;59(2):120-1.
PMID: 16632913

Pantoea infections are uncommon in humans. Most reports have involved adults or children after thorn injuries. There are only a few reports of systemic infections with Pantoea. This is the first report of the clinical picture of systemic Pantoea spp. infection in neonates as observed during an outbreak in a neonatal intensive care unit caused by infected parenteral nutrition solutions. Even though detected early, the infections had a fulminant course, causing septicemic shock and respiratory failure. Pulmonary disease was prominent and presented mainly as pulmonary hemorrhage and adult respiratory distress syndrome. The organism was sensitive to most antibiotics used in neonatal intensive care units, but the clinical response to antibiotic therapy was poor. The fatality rate was very high: 7 out of 8 infected infants succumbed to the infection (87.5%).

Staphylococcal infection in Malaysian hospitals

Lim VK

J Hosp Infect, 1988 Feb;11 Suppl A:103-8.
PMID: 2896692

Staphylococcal infection is common in Malaysian hospitals. A recent survey of 22 Malaysian hospitals revealed that staphylococci were isolated from almost 40% of positive blood cultures. A more detailed analysis of such cases in our own hospital showed that almost 70% of Staphylococcus aureus and about 16% of coagulase-negative staphylococcal isolates were associated with clinically-significant disease. Staphylococcal bacteraemia was seen mainly in neonatal sepsis, skin and soft tissue infections, pneumonia, arthritis, osteomyelitis, endocarditis and postoperative sepsis. Multiply-resistant S. aureus were encountered in all the hospitals surveyed. Resistance rates to penicillin ranged from 40% to almost 100% while methicillin resistance rates of up to 25% were reported from several hospitals.

Six-year study on peripheral venous catheter-associated BSI rates in 262 ICUs in eight countries of South-East Asia: International Nosocomial Infection Control Consortium findings

Rosenthal VD, Bat-Erdene I, Gupta D, Rajhans P, Myatra SN, Muralidharan S, et al.

J Vasc Access, 2021 Jan;22(1):34-41.
PMID: 32406328 DOI: 10.1177/1129729820917259

BACKGROUND: Short-term peripheral venous catheter-associated bloodstream infection rates have not been systematically studied in Asian countries, and data on peripheral venous catheter-associated bloodstream infections incidence by number of short-term peripheral venous catheter days are not available.
METHODS: Prospective, surveillance study on peripheral venous catheter-associated bloodstream infections conducted from 1 September 2013 to 31 May 2019 in 262 intensive care units, members of the International Nosocomial Infection Control Consortium, from 78 hospitals in 32 cities of 8 countries in the South-East Asia Region: China, India, Malaysia, Mongolia, Nepal, Philippines, Thailand, and Vietnam. For this research, we applied definition and criteria of the CDC NHSN, methodology of the INICC, and software named INICC Surveillance Online System.
RESULTS: We followed 83,295 intensive care unit patients for 369,371 bed-days and 376,492 peripheral venous catheter-days. We identified 999 peripheral venous catheter-associated bloodstream infections, amounting to a rate of 2.65/1000 peripheral venous catheter-days. Mortality in patients with peripheral venous catheter but without peripheral venous catheter-associated bloodstream infections was 4.53% and 12.21% in patients with peripheral venous catheter-associated bloodstream infections. The mean length of stay in patients with peripheral venous catheter but without peripheral venous catheter-associated bloodstream infections was 4.40 days and 7.11 days in patients with peripheral venous catheter and peripheral venous catheter-associated bloodstream infections. The microorganism profile showed 67.1% were Gram-negative bacteria: Escherichia coli (22.9%), Klebsiella spp (10.7%), Pseudomonas aeruginosa (5.3%), Enterobacter spp. (4.5%), and others (23.7%). The predominant Gram-positive bacteria were Staphylococcus aureus (11.4%).
CONCLUSIONS: Infection prevention programs must be implemented to reduce the incidence of peripheral venous catheter-associated bloodstream infections.

Six year trend of neonatal septicaemia in a large Malaysian maternity hospital

Boo NY, Chor CY

J Paediatr Child Health, 1994 Feb;30(1):23-7.
PMID: 8148183

A study carried out in the Maternity Hospital, Kuala Lumpur over a 6 year period from 1986 to 1991, showed that the annual rates of septicaemia ranged from 5.2 to 10.2/100 admissions. Septicaemia accounted for between 11.0 to 30.4% of all neonatal deaths. The case fatality ratios ranged from 23.0 to 52.2%, being highest in 1989 when basic facilities were compromised. Low birthweight neonates accounted for 55.5% of those with septicaemia. The most common causative organisms were Staphylococcus epidermidis and Staphylococcus aureus in 1986 and 1987, but from 1988 Klebsiella species became the most common. More than 50% of neonatal septicaemia occurred after the age of 2 days. The results of the study demonstrated the dynamism of infection control: when control measures introduced earlier were not sustained, outbreaks of nosocomial infection recurred or worsened.

Rafiza S, Rampal KG

Int J Tuberc Lung Dis, 2012 Feb;16(2):163-8.
PMID: 22236915 DOI: 10.5588/ijtld.11.0364

BACKGROUND: Serial testing for tuberculosis (TB) exposure has been advocated among health care workers (HCWs) at risk of nosocomial infection.
OBJECTIVE: To determine the incidence and factors associated with TB infection among selected HCWs in Malaysia and to determine interferon-gamma response in serial testing.
DESIGN: A cohort of 769 HCWs were retested after 1 year using QuantiFERON®-TB Gold In-Tube. Incidence of TB infection was determined among HCWs who previously tested negative. Conversion and reversion rates using several definitions were explored.
RESULTS: Incidence of TB infection was 9.9 per 100 workers per year (95%CI 7.9-12.3). Working in the Emergency Department (ED; RR 2.18, 95%CI 1.07-4.43) was significantly associated with risk of TB infection. Reversion and conversion occurred frequently, with 46.7% reversion among HCWs with baseline interferon-gamma (IFN-γ) levels of 0.35-0.70 international units (IU)/ml, and 23.8% conversion among HCWs with baseline IFN-γ levels of 0.20-0.34 IU/ml.
CONCLUSIONS: TB infection control measures need to be strengthened, particularly in the ED, as the incidence of TB was high. Conversion and reversion rates in serial testing were high, and further studies are needed to facilitate its interpretation.

PMID: 28480813 DOI: 10.1177/0300060517706284

Objective To determine risk factors for multi-drug-resistant Acinetobacter baumannii (MDR-AB) nosocomial infections in intensive care units in a tertiary care hospital, Makkah, Saudi Arabia. Methods We performed a hospital-based, matched case-control study in patients who were admitted to Al Noor Specialist Hospital between 1 January 2012 and 31 August 2012. The study included cases of A. baumannii nosocomial infection and controls without infection. Controls were matched to cases by age and ward of admission. Results The most frequent site of infection was the respiratory tract (77.3%). Susceptibility to antimicrobial MDR-AB was 92.0% for ceftazidime and ciprofloxacin, while it was 83.3% for imipenem, 83.0% for trimethoprim, 79.0% for amikacin, and 72.7% for gentamicin. Multiple logistic regression of risk factors showed that immunosuppression (OR = 2.9; 95% CI 1.5-5.6; p = 0.002), clinical outcome (OR = 0.4; 95% CI 0.3-0.9; p = 0.01), invasive procedures (OR = 7.9; 95% CI 1.8-34.2; p = 0.002), a central venous catheter (OR = 2.9; 95% CI 1.5-5.6; p = 0.000), and an endotracheal tube (OR = 3.4; 95% CI 1.6-7.3; p = 0.001) were associated with MDR-AB. Conclusions Acinetobacter nosocomial infections are associated with admission to the ICU (Intensive care unit) and exposure to invasive procedures.

Risk assessment and microbiological profile of infections in paediatric cancer patients with febrile neutropenia

Latiff Z, Zulkifli SZ, Jamal R

Malays J Pathol, 2002 Dec;24(2):83-9.
PMID: 12887165

Febrile neutropenia is a common and potentially fatal problem encountered in cancer patients undergoing chemotherapy. We carried out an observational study to evaluate the possible risk factors of developing fever amongst neutropenic children with an underlying malignancy. We also looked at the microbiological profile of causative pathogens in patients with febrile neutropenia. During a study period of 1 year, a total of 90 neutropenic episodes were recorded amongst 57 patients who were on treatment and follow-up during the study period. Multivariate analysis showed that factors such as chemotherapy status, underlying disease, existing central venous catheters, presenting white blood cell counts at chemotherapy, use of steroid therapy or hospitalisation at the onset of neutropenia, were not significant risk factors for developing fever during neutropenic episodes. Although the presence of a central venous catheter was associated with a higher risk of developing fever, it did not reach statistical significance (p=0.11). Of the 90 neutropenic episodes, 59 (65.6%) developed fever and 25 of these had positive blood cultures. The causative organisms include gram-negative bacteria (64%), gram positive bacteria (16%) and fungus (20%). Of the gram-negative organisms, Klebsiella spp. predominated (28%) with the extended spectrum beta-lactamase producing strain forming the majority (16%). Amongst those with fungaemia, Candida spp. and Candida tropicalis formed the majority (8% each) of the isolates.

Pulsed-field gel electrophoresis of multidrug-resistant and -sensitive strains of Pseudomonas aeruginosa from a Malaysian hospital

Thong KL, Lai KS, Ganeswrie R, Puthucheary SD

Jpn J Infect Dis, 2004 Oct;57(5):206-9.
PMID: 15507777

Over a period of 6 months from January to June 2002, an unusual increase in the isolation of highly resistant Pseudomonas aeruginosa strains was observed in the various wards and intensive care units of a large general hospital in Johor Bahru, Malaysia. An equal number of multidrug resistant (MDR) and drug-susceptible strains were collected randomly from swabs, respiratory specimens, urine, blood, cerebral spinal fluid, and central venous catheters to determine the clonality and genetic variation of the strains. Macrorestriction analysis by pulsed-field gel electrophoresis showed that the 19 MDR strains were genetically very homogenous; the majority showed the dominant profile S1 (n = 10), the rest very closely related profiles S1a (n = 1), S2 (n = 4), and S2a (n = 3), indicating the endemicity of these strains. In contrast, the 19 drug-sensitive strains isolated during the same time period were genetically more diverse, showing 17 pulsed-field profiles (F = 0.50-1.00), and probably derived from the patients themselves. The presence of the MDR clone poses serious therapeutic problems as it may become endemic in the hospital and give rise to future clonal outbreaks. There is also the potential for wider geographical spread.

Fulltext Public Health Risks of Multiple-Drug-Resistant Enterococcus spp. in Southeast Asia

Daniel DS, Lee SM, Dykes GA, Rahman S

Appl Environ Microbiol, 2015 Sep;81(18):6090-7.
PMID: 26150452 DOI: 10.1128/AEM.01741-15

Enterococci rank as one of the leading causes of nosocomial infections, such as urinary tract infections, surgical wound infections, and endocarditis, in humans. These infections can be hard to treat because of the rising incidence of antibiotic resistance. Enterococci inhabiting nonhuman reservoirs appear to play a critical role in the acquisition and dissemination of antibiotic resistance determinants. The spread of antibiotic resistance has become a major concern in both human and veterinary medicine, especially in Southeast Asia, where many developing countries have poor legislation and regulations to control the supply and excessive use of antimicrobials. This review addresses the occurrence of antibiotic-resistant enterococci in Association of Southeast Asian Nations countries and proposes infection control measures that should be applied to limit the spread of multiple-drug-resistant enterococci.
