OBJECTIVE: Poor injection practices transmit potentially life-threatening pathogens. We modelled the cost-effectiveness of policies for the safe and appropriate use of injections in ten epidemiological subregions of the world in terms of cost per disability-adjusted life year (DALY) averted. METHODS: The incidence of injection-associated hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections was modelled for a year 2000 cohort over a 30-year time horizon. The consequences of a "do nothing" scenario were compared with a set of hypothetical scenarios that incorporated the health gains of effective interventions. Resources needed to implement effective interventions were costed for each subregion and expressed in international dollars (I dollars). FINDINGS: Worldwide, the reuse of injection equipment in the year 2000 accounted for 32%, 40%, and 5% of new HBV, HCV and HIV infections, respectively, leading to a burden of 9.18 million DALYs between 2000 and 2030. Interventions implemented in the year 2000 for the safe (provision of single-use syringes, assumed effectiveness 95%) and appropriate (patients-providers interactional group discussions, assumed effectiveness 30%) use of injections could reduce the burden of injection-associated infections by as much as 96.5% (8.86 million DALYs) for an average yearly cost of 905 million I dollars (average cost per DALY averted, 102; range by region, 14-2293). Attributable fractions and the number of syringes and needles required represented the key sources of uncertainty. CONCLUSION: In all subregions studied, each DALY averted through policies for the safe and appropriate use of injections costs considerably less than one year of average per capita income, which makes such policies a sound investment for health care. 相似文献

OBJECTIVE: To identify breaks in infection control practices that might put Romanians at risk for transmission of hepatitis B virus (HBV) from injections. METHODS: A standardized questionnaire was administered to a systematic sample of the 1,906 nurses in Valcea District, Romania, to collect information on their knowledge, attitudes, and practices regarding injection administration and universal precautions. RESULTS: Of the 180 nurses interviewed, 91% (95% confidence interval [CI95], 86% to 95%) reported having attended training for universal precautions; 58% (CI95, 49% to 67%) accurately reported that HBV remains infectious for at least 1 week in the environment; and 4% (CI95, 2% to 8%) knew that HBV is transmitted more efficiently than HIV through percutaneous exposures. No nurses reported reusing syringes or needles on different patients, but 4 (2%; CI, 1% to 6%) would reuse a syringe and 3 (2%; CI95, 0% to 5%) would reuse a needle on the same patient in an emergency. Fifty-three percent (CI95, 44% to 61%) of nurses reported having a dedicated area for the preparation of injectable medications separate from where blood-contaminated items were handled. Shortages of infection control supplies were common. CONCLUSIONS: Although nurses in Valcea do not report reusing injection equipment without sterilization, other unsafe practices occur that may facilitate HBV transmission through injections, including preparing injectable medications in areas potentially contaminated with blood. Inadequate knowledge of blood-borne pathogen transmission and shortages of infection control supplies may contribute to these unsafe practices. Addressing these deficits could improve injection safety in Romania. 相似文献

Background
A nascent HIV epidemic and high prevalence of risky drug practices were detected among injecting drug users (IDUs) in Kabul, Afghanistan from 2005-2006. We assessed prevalence of HIV, hepatitis C virus (HCV), hepatitis B surface antigen (HBsAg), syphilis, and needle and syringe program (NSP) use among this population.Methods
IDUs were recruited between June, 2007 and March, 2009 and completed questionnaires and rapid testing for HIV, HCV, HBsAg, and syphilis; positive samples received confirmatory testing. Logistic regression was used to identify correlates of HIV, HCV, and current NSP use.Results
Of 483 participants, all were male and median age, age at first injection, and duration of injection were 28, 24, and 2.0 years, respectively. One-fifth (23.0%) had initiated injecting within the last year. Reported risky injecting practices included ever sharing needles/syringes (16.9%) or other injecting equipment (38.4%). Prevalence of HIV, HCV Ab, HBSAg, and syphilis was 2.1% (95% CI: 1.0-3.8), 36.1% (95% CI: 31.8-40.4), 4.6% (95% CI: 2.9-6.9), and 1.2% (95% CI: 0.5-2.7), respectively. HIV and HCV infection were both independently associated with sharing needles/syringes (AOR = 5.96, 95% CI: 1.58 - 22.38 and AOR = 2.33, 95% CI: 1.38 - 3.95, respectively). Approximately half (53.8%) of the participants were using NSP services at time of enrollment and 51.3% reported receiving syringes from NSPs in the last three months. Current NSP use was associated with initiating drug use with injecting (AOR = 2.58, 95% CI: 1.22 - 5.44), sharing injecting equipment in the last three months (AOR = 1.79, 95% CI: 1.16 - 2.77), prior incarceration (AOR = 1.57, 95% CI: 1.06 - 2.32), and greater daily frequency of injecting (AOR = 1.40 injections daily, 95% CI: 1.08 - 1.82).Conclusions
HIV and HCV prevalence appear stable among Kabul IDUs, though the substantial number having recently initiated injecting raises concern that transmission risk may increase over time. Harm reduction programming appears to be reaching high-risk drug user populations; however, monitoring is warranted to determine efficacy of prevention programming in this dynamic environment. 相似文献4.

Improving maternal health is one of the Millennium Development Goals of the United Nations. Despite the efforts to promote maternal and neonatal care to achieve this goal, the use of delivery care remains below expectations in Burkina Faso. This situation raises the question of the quality of care offered in maternity wards. The aim of this study was to identify primary healthcare facility and antenatal care characteristics predictive of an assisted delivery in rural Burkina Faso. A cross-sectional study was carried out in Gnagna province (North-East Burkina Faso) in November 2003. The operational capacities of health facilities were assessed, and a non-participating observation of the antenatal care (ANC) procedure was undertaken to evaluate their quality. Scores were established to summarize the information gathered. The rate of professional childbirth (obstetrical coverage) was derived from the number of childbirths registered in the health facility compared to the size of the population. The established scores were related to the obstetrical coverage using non-parametric tests (Kendall). In total, 17 health facilities were visited, and 81 antenatal consultations were observed. Insufficiencies were observed at all steps of ANC (mean total score for the quality of ANC=10.3±3.0, ranging from 6 to 16, out of a maximum of 20). Health facilities are poorly equipped, and the availability of qualified staff remained low (mean total score for the provision of care was 22.9±4.2, ranging from 14 to 33). However, these scores were not significantly related to the rate of professional childbirth (tau Kendall=0.27: p=0.14 and 0.01, p=0.93 respectively). The ability of the primary health centres to provide good antenatal care remains low in rural Burkina Faso. The key factors involved in the limited use of professional childbirth relating to maternal health services may be the quality of ANC.Key words: Antenatal care, Cross-sectional studies, Deliveries, Developing countries, Maternal health services, Obstetric care, Quality of care, Burkina Faso, Africa 相似文献

BACKGROUND: Reported rates of acute hepatitis B are high in many former Soviet Union republics and modes of transmission are not well defined. METHODS: Two case-control studies were undertaken in Moldova to identify risk factors for acute hepatitis B in people aged 2-15 years (children) and > or =15 years (adults). Serologically confirmed acute hepatitis B cases occurring between 1 January 1994 and 30 August 30 1995, were matched on age, sex, and district of residence to three potential controls who were tested for hepatitis B markers to exclude the immune. Stratified odds ratios (SOR) were calculated using bivariate and multivariate methods. RESULTS: In multivariate analysis, compared with the 175 controls, the 70 adult cases (mean age 25 years, 66% male) were more likely to report receiving injections in the 6 months before illness during a dental visit (SOR = 21; 95% CI: 3.7-120), a hospital visit (SOR = 35; 95% CI: 7.2-170), or a visit to the polyclinic (SOR = 13; 95% CI: 2.4-74). Among children, receiving injections during a hospital visit (SOR = 5.2; 95% CI: 1.2-23) was the only exposure reported significantly more often by the 19 cases (mean age 8 years, 68% male) compared with the 81 controls. CONCLUSION: These results, along with reported unsafe injection practices in Moldova, suggest that injections are a major source of hepatitis B virus transmission and highlight the importance of proper infection-control procedures in preventing transmission of blood-borne infections. 相似文献

OBJECTIVES: To determine whether hepatitis B virus (HBV) transmission occurred among patients visiting a physician's office and to evaluate potential transmission mechanisms. DESIGN: Serologic survey, retrospective cohort study, and observation of infection control practices. SETTING: Private medical office. PATIENTS: Those visiting the office between March 1 and December 26, 2001. RESULTS: We identified 38 patients with acute HBV infection occurring between February 2000 and February 2002. The cohort study, limited to the 10 months before outbreak detection, included 91 patients with serologic test results and available charts representing 18 case-patients and 73 susceptible patients. Overall, 67 patients (74%) received at least one injection during the observation period. Case-patients received a median of 14 injections (range, 2-25) versus 2 injections (range, 0-17) for susceptible patients (P < .001). Acute infections occurred among 18 (27%) of 67 who received at least one injection versus none of 24 who received no injections (RR, 13.6; CI95, 2.4-undefined). Risk of infection increased 5.2-fold (CI95, 0.6-47.3) for those with 3 to 6 injections and 20.0-fold (CI95, 2.8-143.5) for those with more than 6 injections. Typically, injections consisted of doses of atropine, dexamethasone, vitamin B12, or a combination of these mixed in one syringe. HBV DNA genetic sequences of 24 patients with acute infection and 4 patients with chronic infection were identical in the 1,500-bp region examined. Medical staff were seronegative for HBV infection markers. The same surface was used for storing multidose vials, preparing injections, and dismantling used injection equipment. CONCLUSION: Administration of unnecessary injections combined with failure to separate clean from contaminated areas and follow safe injection practices likely resulted in patient-to-patient HBV transmission in a private physician's office. 相似文献

The World Health Organization defines 'a safe injection' as one that does not harm the recipient, does not expose the provider to any avoidable risk, and does not result in any waste that is dangerous to the community. Irrational and unsafe injection practices are rife in developing countries. The objective of the present study was to assess the injection practices in the state of Tamilnadu, India, using the Rapid assessment and response guide of the Safe Injection Global Network of the World Health Organization. Thirty-nine prescribers, 62 providers, and 175 members of the general public were interviewed. The areas were chosen out of convenience while at the same time adhering to the guidelines. The study was carried out between April and June 2001. The per capita injection rate was 2.4 per year. The ratio of therapeutic to immunization injections was 6.5:1, and the proportion of injections given with a disposable syringe and needle was 35.4%. Knowledge about diseases transmitted by unsafe injections, for example involving human immunodeficiency virus and hepatitis B virus, was greater among all the study groups. The annual incidence of needlestick injuries among providers was 23.6, which is extremely high. It is concluded that there are deficiencies in practice such as an excessive, unwarranted usage of injections, a sizeable prevalence of unsafe injection practices, the short supply of injection equipment leading to a high incidence of needlestick injuries, a low proportion of hepatitis B virus immunization among providers, and a lack of adequate sharps containers and disposal facilities in this part of India. It is suggested that immediate and long-term remedial measures, such as the education of prescribers to reduce the number of injections to a bare minimum, an adequate supply of injection equipment, provider protection with immunization for hepatitis B virus, the provision of adequate sharps containers with safe disposal facilities and, not least, community education, be undertaken to avoid the future epidemic of transmissible diseases. 相似文献

The objective of this study was to assess the prevalence and the contribution of socio-demographic factors and chronic diseases to mobility disability in West African countries. Data were obtained from the World Health Survey (2002-2003) in which adults≥18 years participated, from Burkina Faso (n=4822), Mali (n=4230) and Senegal (n=3197). Participants reporting mild, moderate, severe, extreme difficulty or inability to move around were defined as having mobility disability. All estimates were corrected for sampling design. Association measures were estimated using logistic regression methods. Mobility disability was frequent at young ages (35-44 years old) in men and women, respectively: 17% and 23% in Burkina Faso, 12% and 23% in Mali and 22% and 34% in Senegal. Women had higher odds of mobility difficulty than men at every age group in the three countries: 1.34 (95%CI 1.06; 1.70) in Burkina Faso; 2.33 (95% CI 1.84; 2.71) in Mali and 1.82 (95%CI 1.41; 2.36) in Senegal. Controlling for socio-economic factors and chronic disease, these odds changed respectively to 0.94 (95%CI 0.70; 1.25), 2.19 (95%CI 1.61; 2.96) and 1.90 (95%CI 1.27; 2.84). These results constitute a benchmark for the study of trends of mobility disability in West Africa and could be used by policy planners. 相似文献

BackgroundA new serogroup A meningococcal conjugate vaccine (PsA-TT, MenAfriVac™) has been developed to combat devastating serogroup A Neisseria meningitis (MenA) epidemics in Africa. A mass immunization campaign targeting 1–29 year olds was conducted in Burkina Faso in December 2010. Protection of subsequent infant cohorts will be necessary through either introduction of PsA-TT into the routine Expanded Programme on Immunization (EPI) or periodic repeat mass vaccination campaigns.ObjectivesTo inform future immunization policy for PsA-TT vaccination of infants through a comparison of PsA-TT campaign vaccination coverage and routine measles-containing vaccine (MCV) coverage in Burkina Faso.MethodsA national survey was conducted in Burkina Faso during December 17–27, 2011 using stratified cluster sampling to assess PsA-TT vaccine coverage achieved by the 2010 nationwide immunization campaign among 2–30 year olds and routine MCV coverage among 12–23 month olds. Coverage estimates and 95% Confidence Intervals (CI) were calculated, reasons for non-vaccination and methods of campaign communication were described, and a multivariable analysis for factors associated with vaccination was conducted.ResultsNational overall PsA-TT campaign coverage was 95.9% (95% CI: 95.0–96.7) with coverage greater than 90% all 13 regions of Burkina Faso. National overall routine MCV coverage was 92.5% (95% CI: 90.5–94.1), but ranged from 75.3% to 95.3% by region. The primary predictor for PsA-TT vaccination among all age groups was a head of household informed of the campaign. PsA-TT vaccination was more likely in residents of rural settings, whereas MCV vaccination was more likely in residents of urban settings.ConclusionOverall national vaccination rates in Burkina Faso were similar for PsA-TT and MCV vaccine. The regions with MCV coverage below targets may be at risk for sub-optimal vaccination coverage if PsA-TT is introduced in EPI. These results highlight the need for assessments of routine vaccination coverage to guide PsA-TT immunization policy in meningitis belt countries. 相似文献

ObjectiveTo explore the level, geographical disparities and sociodemographic determinants of cervical cancer screening uptake among adult women in Burkina Faso by using data from the first national population-based survey.MethodsThis was a cross-sectional secondary analysis of primary data obtained by the 2013 World Health Organization (WHO) Stepwise Approach to Surveillance survey conducted in Burkina Faso. All 13 Burkinabè regions, with their different rates of urbanization, were surveyed. Lifetime cervical cancer screening uptake was explored. We included 2293 adult women for analyses and performed Student's t, chi-square and Fisher's exact tests, and logistic regression.ResultsOnly 6.2% (95% CI: 5.3–7.3) of women had ever been screened for cervical cancer. For two regions (“Centre” and “Hauts-Bassins”), the pooled frequency was 16.6% (95% CI: 13.5–20.1) while in the other eleven regions it was significantly lower, 3.3% (95% CI: 2.5–4.2). In urban and rural areas, the respective frequencies for the screening uptake were 18.5% and 2.8% (p < 0.001), and in educated and un-educated women, frequencies were 27.7% and 3.3% (p < 0.001) respectively. The sociodemographic factors associated with screening uptake were being educated (adjusted odd-ratio [aOR] = 4.3; 95% CI: 2.8–6.7), urban residence (aOR = 3.8, 95% CI: 2.5–5.8) and having an occupation providing income (aOR = 3.1, 95% CI: 1.8–5.4).ConclusionThere was a significantly wide range in screening uptake between Burkina Faso regions, and the overall national as well as the region-specific levels were far below the WHO's target for cervical cancer elimination. Cervical cancer interventions should be tailored specifically for Burkinabè women with different educational levels, and prevention strategies based on community engagement integrating psychosocial considerations could be helpful. 相似文献

A cross-sectional study was conducted in 25 health care facilities in Gharbiya governorate to assess safe injection practices among health care workers (HCWs). Two questionnaires, one to collect information about administrative issues related to safe injection and the other to collect data about giving injections, exposure to needle stick injuries, hepatitis B vaccination status and safe injection training. Practices of injections were observed using a standardized checklist. The study revealed that there was lack of both national and local infection control policies and lack of most of the supplies needed for safe injection practices. Many safe practices were infrequent as proper needle manipulation before disposal (41%), safe needle disposal (47.5%), reuse of used syringe & needle (13.2%) and safe syringe disposal (0%). Exposure to needle stick injuries were common among the interviewed HCWs (66.2%) and hand washing was the common post exposure prophylaxis measure (63.4%). Only 11.3% of HCWs had full course hepatitis B vaccination. Infection control -including safe injections- training programs should be afforded to all HCWs. 相似文献

OBJECTIVE: To evaluate vaccine effectiveness and to assess risk factors for measles in Dhaka, Bangladesh. METHOD: A case-control study, involving 198 cases with 783 age-matched neighbourhood controls and 120 measles cases with 365 age-matched hospital controls, was conducted in 1995-96 in three large hospitals in Dhaka. FINDINGS: Measles vaccine effectiveness was estimated at 80% (95% confidence interval (CI) = 60-90%) using neighbourhood controls; very similar results were obtained using hospital controls. Visits to a health facility 7-21 days before onset of any symptoms were associated with increased risk of measles compared with neighbourhood (adjusted odds ratio (OR) = 7.0, 95% CI = 4.2-11.6) or hospital (adjusted OR = 1.7, 95% CI = 1.01-2.8) controls. Cases were more likely than controls to come from a household where more than one child lived (adjusted OR = 1.6, 95% CI = 1.1-2.5 versus neighbourhood controls; adjusted OR = 1.8, 95% CI = 1.02-3.0 versus hospital controls). CONCLUSIONS: To improve measles control in urban Dhaka missed immunization opportunities must be reduced in all health care facilities by following WHO guidelines. For measles elimination, more than one dose of vaccine would be required. 相似文献

OBJECTIVE: Reused syringes have been identified as a major risk factor for hepatitis B and C in Pakistan, a country facing a growing epidemic of these infections. We conducted this study to identify factors associated with receiving at least one injection during the past 3 months in an urban and a rural area in the Sindh province of Pakistan. METHODS: A population-based cross-sectional study of individuals aged 3 months was conducted in 34 clusters in an urban and a rural setting. Information was obtained on the number of contacts with healthcare providers and the number of injections received during the past 3 months. Beliefs about the efficacy of injections were also tested. Multivariable logistic regression analysis was performed to identify factors associated with receiving at least one injection during the past 3 months. RESULTS: Of 1150 subjects who participated in the study, 848 (74%) reported having received at least one injection during the past 3 months. Seventy-one percent (815/1150) believed that injections act faster than oral drugs and relieve symptoms quickly. There was a lack of risk perception among the participants: 19% (222/1150) believed that injections involve less risk than do oral drugs. Multivariable logistic regression analysis revealed that individuals who had visited unqualified practitioners (adjusted OR=6.1; 95% CI: 2.6-14.1) or general practitioners (adjusted OR=3.4; 95% CI: 1.9-6.0) were more likely to have received an injection. Belief that 'injections act faster and relieve symptoms quickly' had a multiplicative interaction with the area of dwelling: people in rural areas who held this belief were more likely to receive injections than people who did not hold this belief and were living in urban areas. CONCLUSIONS: In Pakistan, people's lack of awareness of risks associated with injections and their strong belief in the fast action of injections are driving injection overuse. These factors are supplemented by general practitioners' and unqualified providers' inclinations to prescribe more injections. Efforts must be made to include the unqualified practitioners in any interventions aimed to reduce injection overuse in Pakistan. 相似文献

OBJECTIVES. To guide development of a hepatitis B control program in China, we investigated village doctors' sterilization practices, injection use, vaccination levels, and knowledge and counseling skills. METHODS. The head doctor from each village health station in a rural county (n = 260) completed a self-administered questionnaire. RESULTS. Of the respondents, 94.2% reported adequate sterilization of needles; however, inadequate sterilization of syringes and acupuncture needles was common. Injections were found to be frequent and profitable. Of head doctors, 16.2% reported that most infants in their villages are vaccinated against hepatitis B. There was very high knowledge of modes of hepatitis B transmission, but it was not used to formulate advice for a hypothetical carrier. Knowledge of the consequences, prevalence, and use of condoms to prevent sexual transmission was lower. CONCLUSIONS. The sterilization of acupuncture needles, reuse of syringes, and frequent injections are practices that may transmit the hepatitis B virus. Research into issues of vaccine acceptance is needed to expand immunization. A review of treatment practices and better training in counseling for village doctors is suggested. 相似文献

Unsafe injections in low-income country health settings: need for injection safety promotion to prevent the spread of blood-borne viruses 总被引:2,自引:0,他引:2
Kermode M 《Health promotion international》2004,19(1):95-103
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. 相似文献

Biomass solid fuel smoke is linked to acute respiratory infections (ARI). In future, its use will likely increase among poor households, and better ventilation is one important measure that can reduce this health impact. The authors aimed to study the extent to which improvement in ventilation-related factors reduces the fraction of ARI attributable to exposure to biomass smoke in children under 5 years old. An explorative study was carried out in 2004 by applying a questionnaire on 51 households randomly selected from a health district in Burkina Faso. The prevalence of exposure in the population was estimated using ventilation coefficients, and proportions of households with different stove types and locations. An attributable fraction of 0.56 (95% CI: 0.47-0.62) was estimated using the traditional formula for attributable fraction, and 0.26 (95% CI: 0.19-0.31) after weighting exposure by ventilation coefficients, stove type and location. Two scenarios were created: (1) Assuming that most households cooked inside, the fraction becomes 0.54 (95% CI: 0.45-0.61). (2) Assuming that indoor ventilation and cooking device are improved by 20%, the fractions decreased slightly. Improving cooking devices and indoor ventilation reduces the fraction of ARI in children under 5 years attributable to exposure to biomass smoke, but a higher reduction is achieved by cooking outdoors. 相似文献

ObjectiveTo evaluate the implementation of a screening strategy for the partners and children of pregnant women with hepatitis B virus (HBV) attending antenatal care.MethodsWe identified pregnant women positive for HBV surface antigen (HBsAg) at antenatal consultation in Ouagadougou, Burkina Faso. At post-test counselling, women were advised to disclose their HBV status to partners and to encourage their partner and children to be screened for HBsAg. We used multivariable logistic regression to explore factors associated with uptake of screening and HBsAg positivity among family members.FindingsOf 1000 HBsAg-positive women, 436/1000 partners and 215/1281 children were screened. HBsAg was detected in 55 (12.6%) partners and 24 (11.2%) children. After adjusting for confounders, uptake of screening was higher in partners who were married, who attended the woman’s first post-test consultation and to whom the woman had disclosed her HBV status. In children, HBsAg positivity was associated with being born before the introduction of infant hepatitis B vaccination in Burkina Faso (not significant in the multivariable analysis), having a mother positive for HBV e-antigen (adjusted OR: 8.57; 95% CI: 2.49–29.48) or having a mother with HBV DNA level ≥ 200 000 IU/mL (OR: 6.83; 95% CI: 1.61–29.00).ConclusionIn low-income countries, the antenatal consultation provides a cost-effective opportunity to identify HBV-infected household contacts and link them to care. Children born before the introduction of infant hepatitis B vaccination and whose mother has higher viral load or infectivity should be a priority for testing and linkage to care. 相似文献

目的:了解重庆市武隆县医疗机构安全注射现况,为采取干预措施提供依据。方法:用统一设计的调查表对注射服务机构和人员进行调查。结果:52.2%(12/23)的医疗机构玻璃注射器消毒不合格、31.4%(11/35)的医疗机构注射操作不正确、63.6%(21/33)的医疗机构直接丢弃用过的一次性注射器。存在以上至少1种不安全注射行为的医疗机构有77.1%(27/35)。结论:青霉素皮肤过敏试验共用针管的不正确操作、医务工作者销毁注射器被刺伤、一次性注射器卫生质量管理空白是目前主要的不安全因素。培训医务人员的正确注射行为、重视一次性注射器的卫生质量管理和用后的安全处理是提高安全注射水平的重要措施。 相似文献
