Prevalence of hospital-associated infections can be decreased effectively in developing countries

BACKGROUND

Hospital-acquired infections (HAI) are an important public health problem worldwide. Little information is available from African countries, but published data show that the burden of HAI is greater in Africa than in developed countries. In 2002, the World Health Organization (WHO) published guidelines for preventing HAI.

AIM

To evaluate the impact of a hospital infection control programme on the prevalence of HAI among patients in a large Ugandan hospital.

METHODS

A one-day cross-sectional prevalence survey and a ward procedure survey were performed in Lacor Hospital in March 2010 using standardized questionnaires. All patients admitted to hospital not less than two days before the survey were eligible to participate in the prevalence survey. Modified WHO criteria for HAI were used. The ward procedure survey examined the procedures to prevent HAI. Several hospital infection control measures were subsequently implemented, in accordance with WHO infection control guidelines, starting in October 2010. The prevalence survey and ward procedure survey were repeated in October 2011.

FINDINGS

The prevalence of HAI was 34% in 2010 and 17% in 2011. The prevalence of infected patients reduced from 28% to 14%. The prevalence of HAI was lower in all age groups and for all types of HAI except urinary tract infections following the implementation of infection control activities.

CONCLUSION

This study showed that HAI is an important problem in this large African hospital, and that the prevalence of HAI can be reduced effectively following the adoption of basic infection control procedures.

The prevalence and antibiotics susceptibility pattern of Neisseria gonorrhoeae in patients attending OPD clinics at St. Mary's Hospital Lacor Uganda

INTRODUCTION

Gonorrhea is one of the most common sexually transmitted infections (STls) in developing countries, and the emergence of resistance to antimicrobial agents in Neisseria gonorrhoeae is a major obstacle in the control of gonorrhoea. Periodical determination of the prevalence and monitoring of antimicrobial susceptibility of N. gonorrhoeae is essential for the early detection of emergence of drug resistance.

METHODS

A total of 640 consecutive patients who attended the Outpatient Department (OPD) Clinics at St. Mary's Hospital Lacor between Jan 2007-Dec 2011, with gonococcal urethriris symptoms and whose urethral swabs and high vagina swabs (HVS) were cultured, were involved in the study. Two hundred and fifty six (256) patients had positive pus swab culture, of which 151 (23.6%) showed growth of Neisseria gonorrhoeae. All the isolates were tested for antimicrobial susceptibility using the Kirby Bauer-disc diffusion techniques.

RESULTS

Gonococcal isolates showed rapid decrease in susceptibility to the antimicrobials especially to ampicillin, tetracycline and erythomycin, ciprofloxacin, and intermediate to chloramphenicol, however, gentamicin and cefotaxime have remained as a single dose sensitive treatment for Neisseria gonorrhoeae. Sensitization on drug use and adopting preventive measures and continuous education on safer sexual behavior through health care authorities would lead to reduction in the prevalence of Neisseria gonorrhoeae and resistance to antimicrobial.

DISCUSSION

Gonorrhea is one of the most common sexually transmitted infections (STIs) in developing countries, and the emergence of resistance to antimicrobial agents in Neisseria gonorrhoeae is a major obstacle in the control of gonorrhea. Periodical monitoring of antimicrobial susceptibility of N. gonorrhea is essential for the early detection of emergence of drug resistance.

Investigating factors associated with uptake of HIV voluntary counselling and testing among pregnant women living in North Uganda

We investigated factors potentially associated with the uptake of HIV voluntary counselling and testing (VCT), which is the first step in acceding to programmes for the prevention of mother-to-child transmission of HIV infection. For the period 2001-2003, we estimated the VCT uptake among the 12,252 first-time attendees of the Antenatal Clinic (ANC) at Lacor Hospital (Gulu District, North Uganda). Associations between VCT uptake and socio-demographic characteristics and reproductive history were evaluated using log binomial regression models. VCT uptake was 55.6% for the overall study period; it increased from 51.0% in 2001 to 58.6% in 2002 and 57.7% in 2003 (P <0.001). Having some education [primary versus none, adjusted prevalence proportion ratio (PPR) =1.05, 95% confidence intervals (CI): 1.00-1.10] and being unmarried (cohabitating, PPR =1.07, 95% CI: 1.03-1.10; single/widowed/divorced, PPR =1.10, 95% CI: 1.03-1.18) were significantly associated with VCT uptake. Associations of borderline significance were found for: recent change of residence, having a partner with a modern occupation, and past use of contraceptives. VCT uptake is still low in this district of North Uganda. Although some socio-demographic factors were found to have been associated with uptake, the associations were weak and not of public-health significance.

The disease profile of poverty: morbidity and mortality in northern Uganda in the context of war, population displacement and HIV/AIDS

The population of Gulu District (northern Uganda) has been severely incapacitated by war, epidemics and social disruption. This study is aimed at describing disease patterns and trends in this area through a retrospective analysis of discharge records for 155205 in-patients of Lacor Hospital in the period 1992-2002. The burden of infectious diseases in childhood is overwhelming, with malaria accounting for the steepest increase in admissions. Admissions for war-related injuries and malnutrition fluctuated with the intensity of the war and the severity of famine. Emerging and re-emerging infections, such as HIV/AIDS, tuberculosis and Ebola, accounted for a heavy disease burden; however, there has been a trend for admissions related to HIV/AIDS and tuberculosis to decrease since the implementation of community-based services. Vulnerable groups (infants, children and women) accounted for 79.8% of admissions. Long-term war, population displacement, the collapse of social structures and the breakdown of the health system place people at a much greater risk of persistent, emerging and re-emerging infectious diseases, malnutrition and war-related injuries, shaping the 'disease profile of poverty'. Most of the disease burden results from infectious diseases of childhood, whose occurrence could be dramatically reduced by low-cost and effective preventive and curative interventions.
