Occupational exposure to body fluids among health care workers in Georgia
Butsashvili M , Kamkamidze G , Kajaia M , Morse DL , Triner W , Dehovitz J , McNutt LA . Occup Med (Lond) 2012 62 (8) 620-6 BACKGROUND: Health care workers (HCWs) are at increased risk of being infected with blood-borne pathogens. AIMS: To evaluate risk of occupational exposure to blood-borne viruses and determine the prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) among HCWs in Georgia. METHODS: The sample included HCWs from seven medical institutions in five cities in Georgia. A self-administered questionnaire was used to collect information on demographic, occupational and personal risk factors for blood-borne viruses. After obtaining informed consent, blood was drawn from the study participants for a seroprevalence study of HBV, HCV and HIV infections. RESULTS: There were 1386 participating HCWs from a number of departments, including surgery (29%), internal medicine (19%) and intensive care (19%). Nosocomial risk events were reported by the majority of HCWs, including accidental needlestick injury (45%), cuts with contaminated instruments (38%) and blood splashes (46%). The most frequent risk for receiving a cut was related to a false move during a procedure, reassembling devices and handing devices to a colleague. The highest proportion of needlestick injuries among physicians (22%) and nurses (39%) was related to recapping of used needles. No HIV-infected HCW was identified. Prevalence of HCV infection was 5%, anti-HBc was present among 29% with 2% being HBsAg carriers. CONCLUSIONS: Data from this study can be utilized in educational programs and implementation of universal safety precautions for HCWs in Georgia to help achieve similar reductions in blood-borne infection transmission to those achieved in developed countries. |
A national case-control study identifies human socio-economic status and activities as risk factors for tick-borne encephalitis in Poland
Stefanoff P , Rosinska M , Samuels S , White DJ , Morse DL , Randolph SE . PLoS One 2012 7 (9) e45511 BACKGROUND: Tick-borne encephalitis (TBE) is endemic to Europe and medically highly significant. This study, focused on Poland, investigated individual risk factors for TBE symptomatic infection. METHODS AND FINDINGS: In a nation-wide population-based case-control study, of the 351 TBE cases reported to local health departments in Poland in 2009, 178 were included in the analysis. For controls, of 2704 subjects (matched to cases by age, sex, district of residence) selected at random from the national population register, two were interviewed for each case and a total of 327 were suitable for the analysis. Questionnaires yielded information on potential exposure to ticks during the six weeks (maximum incubation period) preceding disease onset in each case. Independent associations between disease and socio-economic factors and occupational or recreational exposure were assessed by conditional logistic regression, stratified according to residence in known endemic and non-endemic areas. Adjusted population attributable fractions (PAF) were computed for significant variables. In endemic areas, highest TBE risk was associated with spending ≥10 hours/week in mixed forests and harvesting forest foods (adjusted odds ratio 19.19 [95% CI: 1.72-214.32]; PAF 0.127 [0.064-0.193]), being unemployed (11.51 [2.84-46.59]; 0.109 [0.046-0.174]), or employed as a forester (8.96 [1.58-50.77]; 0.053 [0.011-0.100]) or non-specialized worker (5.39 [2.21-13.16]; 0.202 [0.090-0.282]). Other activities (swimming, camping and travel to non-endemic regions) reduced risk. Outside TBE endemic areas, risk was greater for those who spent ≥10 hours/week on recreation in mixed forests (7.18 [1.90-27.08]; 0.191 [0.065-0.304]) and visited known TBE endemic areas (4.65 [0.59-36.50]; 0.058 [-0.007-0.144]), while travel to other non-endemic areas reduced risk. CONCLUSIONS: These socio-economic factors and associated human activities identified as risk factors for symptomatic TBE in Poland are consistent with results from previous correlational studies across eastern Europe, and allow public health interventions to be targeted at particularly vulnerable sections of the population. |
Human papillomavirus vaccine uptake and barriers: association with perceived risk, actual risk and race/ethnicity among female students at a New York State university, 2010
Bednarczyk RA , Birkhead GS , Morse DL , Doleyres H , McNutt LA . Vaccine 2011 29 (17) 3138-43 Understanding human papillomavirus (HPV) vaccine uptake patterns is critical to improve vaccination levels. Approximately half (56%) of female undergraduate students surveyed at a large public university reported HPV vaccine series initiation, with 79% of initiators completing the three dose series. Predictors of series initiation included having a conversation with a health-care provider about the vaccine, reporting a history of sexual intercourse and receipt of the meningitis vaccine. Compared to whites, black/African-American women were 33% less likely to have initiated HPV vaccination. Common reasons for not receiving the HPV vaccine included concerns about vaccine safety and doctors' not recommending vaccination. |
Reduction in hospitalizations for diarrhea and rotavirus infections in New York state following introduction of rotavirus vaccine
Chang HG , Smith PF , Tserenpuntsag B , Markey K , Parashar U , Morse DL . Vaccine 2010 28 (3) 754-8 OBJECTIVES: To monitor trends and costs of diarrhea and rotavirus-associated hospitalizations in New York before and after rotavirus vaccine implementation in 2006. To examine rotavirus test results from sentinel hospital-associated laboratories. METHODS: Hospital discharge data and laboratory rotavirus testing data were analyzed for children 1 month up to 18 years of age for 10 sentinel and all statewide hospitals from January 1, 2003 through December 31, 2008. RESULTS: Among children 1-23 months of age, a 40% reduction in diarrhea-associated hospitalizations and 85% decrease in rotavirus-coded hospitalizations at the 10 sentinel hospitals was observed in 2008 compared with the average of pre-vaccine seasons from 2003 through 2006. For both sentinel and statewide hospitals, the percent of diarrhea admissions due to rotavirus was reduced at least 83% among children 1-23 months (vaccine eligible) and 70% for older unimmunized children. Statewide hospital costs for rotavirus hospitalizations in children <2 years of age were reduced $10 million. Sentinel hospital laboratory data validated the declining trends seen in hospitalizations. CONCLUSIONS: In 2008, New York hospital data showed significant reductions in rotavirus hospitalizations and costs among children aged 1-23 months who were eligible for vaccine. Reductions also occurred among unimmunized older children suggesting the importance of continue monitoring in future seasons to fully assess vaccine impact. |
