Are healthcare workers at higher risk of HIV infection than the general population in Burkina Faso?

Prevalence and risk factors to HIV-infection amongst health care workers within public and private health facilities in Cameroon

Introduction

This study aimed at assessing the prevalence of Human Immunodeficiency Virus (HIV) among health care workers (HCWs) and to evaluate some risks factors for HCWs.

Methods

We conducted a cross sectional study amongst HCWs in public and private healthcare facilities within seven regions amongst the 10 found in Cameroon. We collected data from 446 HCWs within 150 healthcare facilities. We used questionnaires for interviews and biological sampling for HIV test.

Results

HIV prevalence was 2.61% (95% CI: 1.32% - 4.61%) regardless of gender and age. HCWs in private health facilities were more infected compared to those in public health facilities 5.00% vs 1.40% (p = 0.028); OR = 3.7 (95% CI: 1.01-12.90). HCWs who had never screened for HIV had a high risk of being infected OR = 7.05 (95% CI: 2.05-24.47). 44.62% of HCWs reported to have been victim of an Accidental Exposure to Blood (AEB). Amongst them, 45.80% in public HF versus 32.1% in private HF reported to have received an HIV screening and Post Exposure Prophylaxis following this incident. 4.20% of HCW victim of AEB were HIV positive, and 36.40% of HCWs had appropriate capacity training for HIV patient care.

Conclusion

Though the HIV prevalence in HCWs is lower than in the general population 2.61% vs 4.3%, there is a high risk of infection as we observed a relatively high percentage of AEB amongst HCWs with an HIV prevalence of 4.20%. There is thus, a need in strengthening the capacity and provide psychosocial support to HCWs.

Post exposure prophylaxis following occupational exposure to HIV: a survey of health care workers in Mbeya, Tanzania, 2009-2010

INTRODUCTION

Approximately, 1,000 HIV infections are transmitted annually to health care workers (HCWs) worldwide from occupational exposures. Tanzania HCWs experience one to nine needle stick injuries (NSIs) per year, yet the use of post-exposure prophylaxis (PEP) is largely undocumented. We assessed factors influencing use of PEP among HCWs following occupational exposure to HIV.

METHODS

A cross-sectional study was conducted in Mbeya Referral Hospital, Mbozi and Mbarali District Hospitals from December 2009 to January 2010 with a sample size of 360 HCWs. Participants were randomly selected from a list of eligible HCWs in Mbeya hospital and all eligible HCWs were enrolled in the two District Hospitals. Information regarding risk of exposure to body fluids and NSIs were collected using a questionnaire. Logistic regression was done to identify predictors for PEP use using Epi Info 3.5.1 at 95% confidence interval.

RESULTS

Of 291 HCWs who participated in the study, 35.1% (102/291) were exposed to NSIs and body fluids, with NSIs accounting for 62.9% (64/102). Exposure was highest among medical attendants 38.8% (33/85). Out of exposed HCWs, (22.5% (23/102) used HIV PEP with females more likely to use PEP than males. Reporting of exposures (OR=21.1, CI: 3.85-115.62) and having PEP knowledge (OR =6.5, CI: 1.78-23.99) were significantly associated with using PEP.

CONCLUSION

Despite the observed rate of occupational exposure to HCWs in Tanzania, use of PEP is still low. Effective prevention from HIV infection at work places is required through proper training of HCWs on PEP with emphasis on timely reporting of exposures.

Quality of life in people living with HIV: a cross-sectional study in Ouagadougou, Burkina Faso

HIV/AIDS is a leading cause of death in most of sub-Saharan countries. HIV/AIDS impact on the quality of life of persons living with HIV in Burkina Faso hasn't been well documented. The aim of the study was to assess the quality of life in persons living with HIV and its associated factors.

A cross-sectional study was conducted in Ouagadougou. 424 persons living with HIV were included in the study according to their status with regard to Highly Active Anti Retroviral Treatment: 115 were not yet under treatment, 21 started the treatment within the three months preceding the enrolment and 288 were under treatment for at least 12 months. The quality of life was assessed through the WHOQOL HIV-BREF. Statistical comparisons were made using Mann Whitney U test, Kruskal-Wallis H test, Pearson's khi2 or Fisher's exact test. Correlations were appreciated using Spearman's rho. Logistic regression was used to examine associations between the quality of life scores and sociodemographic or clinical variables.

The mean global score of quality of life in all patients was 82.4. Better scores were recorded in the spiritual domain and worst scores in the environmental domain. Men had a higher global score than women (p < 0.001). Illiteracy was significantly associated with a lower quality of life (p = 0.001). Patients having support for medical treatment had a significantly better quality of life (p < 0.01). In multivariate analysis, being a man, having a support for medical care, getting older and self-perceived as healthy, were associated with a global score of quality of life higher than 77, that corresponds to the mid-range of the score in our data.

These findings suggest the importance of the socio-psychological support and of a good environment in order to improve the quality of life of people living with HIV, especially in women, in younger and in those having no support for medical care. In the environmental domain, actions of HIV services providers should focus on better accessibility to social and health care, promotion of income-generating activities especially for women and youth living with HIV.
