ItemUnsafe injections in low-income country health settings: need for injection safety promotion to prevent the spread of blood-borne viruses(OXFORD UNIV PRESS, 2004-03-01)Injections are one of the most frequently used medical procedures. The World Health Organization (WHO) estimates that 12 billion injections are given annually, 5% of which are administered for immunization and 95% for curative purposes. Unsafe injection practices (especially needle and syringe re-use) are commonplace in low-income country health settings, and place both staff and patients at risk of infection with blood-borne viruses (BBVs). It is estimated that up to 160000 human immunodeficiency virus (HIV), 4.7 million hepatitis C and 16 million hepatitis B infections each year are attributable to these practices. The problem is complex and fueled by a mixture of socio-cultural, economic and structural factors. An appropriate response on the part of international organizations, governments, health administrators, community organizations and health workers, including those who work in the area of HIV/AIDS prevention, has been slow to emerge. This paper reviews the literature relating to unsafe injection practices and the transmission of BBVs in low-income countries in order to raise awareness of the issue and the consequent need to promote injection safety messages amongst both consumers and providers of health care services in these countries. The nature and extent of unsafe injection practices, the burden of blood-borne viral illness attributable to unsafe injection practices, and the factors contributing to these practices are summarized, and possible strategies for promoting injection safety discussed.

ItemSafer injections, fewer infections: injection safety in rural north India(WILEY, 2005-05)BACKGROUND: Unsafe injection practices result in a substantial burden of preventable blood-borne viral disease (BBV). The reasons are complex and include structural, economic and socio-cultural factors. OBJECTIVE: To describe injection-related practices in two rural north Indian health settings including the contextual factor, highlight some of the challenges facing those endeavouring to translate injection safety policies into safe injection practice, and to identify appropriate intervention strategies. METHOD: Qualitative data collection (participant observation and in-depth interviews) in two rural north Indian hospitals with affiliated community-based programmes over a 4-month period. A total of 130 h of observation took place in a range of clinical areas characterized by frequent use of needles and other sharps, and 40 healthcare workers were interviewed. Field notes and interview transcripts were thematically analysed. RESULTS: Managers in these health settings were clearly endeavouring to promote injection safety by implementing the widespread use of disposable needles and syringes and attempting to address the difficult issue of safe healthcare waste management. However, some unsafe practices were still occurring: reuse of syringes (with and without sterilization) was relatively common, and use of multi-dose vials, blood sampling, sterilization and disinfection, and healthcare waste management were sub-optimal in some instances, placing both staff and patients at unnecessary risk of BBV infection. CONCLUSION: Strategies for promoting injection safety are necessary if the risk of nosocomial transmission of BBV diseases via unsafe injection practices in rural north India is to be minimized.

ItemOccupational exposure to blood and risk of bloodborne virus infection among health care workers in rural north Indian health care settings(MOSBY, INC, 2005-02)BACKGROUND: Approximately 3 million health care workers (HCWs) experience percutaneous exposure to bloodborne viruses (BBVs) each year. This results in an estimated 16,000 hepatitis C, 66,000 hepatitis B, and 200 to 5000 human immunodeficiency virus (HIV) infections annually. More than 90% of these infections are occurring in low-income countries, and most are preventable. Several studies report the risks of occupational BBV infection for HCWs in high-income countries where a range of preventive interventions have been implemented. In contrast, the situation for HCWs in low-income countries is not well documented, and their health and safety remains a neglected issue. OBJECTIVE: To describe the extent of occupational exposure to blood and the risk of BBV infection among a group of HCWs in rural north India. METHODS: A cross-sectional survey of HCWs from 7 rural health settings gathered data pertaining to occupational exposure to blood and a range of other relevant variables (eg, demographic information, compliance with Universal Precautions, perception of risk, knowledge of BBVs). A mass action model was used to estimate the risk of occupational BBV infection for these HCWs over a 10-year period. RESULTS: A total of 266 HCWs returned questionnaires (response rate, 87%). Sixty-three percent reported at least 1 percutaneous injury (PI) in the last year (mean no. = 2.3) and 73% over their working lifetime (mean no. = 4.2). Predictors of PI during the last year were hospital site, job category, perception of risk, and compliance with Universal Precautions. CONCLUSION: The high level of occupational exposure to blood found among this group of rural north Indian HCWs highlights the urgent need for interventions to enhance their occupational safety to prevent unnecessary nosocomial transmission of BBVs.

ItemCompliance with universal/standard precautions among health care workers in rural north India(MOSBY-ELSEVIER, 2005-02)BACKGROUND: Universal Precautions (UPs) and more recently Standard Precautions have been widely promoted in high-income countries to protect health care workers (HCWs) from occupational exposure to blood and the consequent risk of infection with bloodborne pathogens. In low-income countries, the situation is very different: UPs are often practiced partially, if at all, thereby exposing the HCWs to unnecessary risk of infection. The aim of this study is to describe rural north Indian HCWs knowledge and understanding of UPs and identify predictors of compliance to target intervention programs appropriately. METHODS: A cross-sectional survey was undertaken, involving 266 HCWs (response rate, 87%) from 7 rural north Indian health care settings. Information was gathered regarding compliance with UPs and a range of other relevant variables that potentially influence compliance (eg, demographic information, perception of risk, knowledge of bloodborne pathogen transmission, perception of safety climate, and barriers to safe practice). RESULTS: Knowledge and understanding of UPs were partial, and UPs compliance was suboptimal, eg, only 32% wore eye protection when indicated, and 40% recapped needles at least sometimes. After controlling for confounding, compliance with UPs was associated with being in the job for a longer period, knowledge of bloodborne pathogen transmission, perceiving fewer barriers to safe practice and a strong commitment to workplace safety climate. CONCLUSION: Interventions to improve UPs compliance among HCWs in rural north India need to address not only their knowledge and understanding but also the safety climate created by the organizations that employ them.
