CDC Clinical Practice Guideline for Prescribing Opioids for Pain - United States, 2022
Dowell D , Ragan KR , Jones CM , Baldwin GT , Chou R . MMWR Recomm Rep 2022 71 (3) 1-95 This guideline provides recommendations for clinicians providing pain care, including those prescribing opioids, for outpatients aged ≥18 years. It updates the CDC Guideline for Prescribing Opioids for Chronic Pain - United States, 2016 (MMWR Recomm Rep 2016;65[No. RR-1]:1-49) and includes recommendations for managing acute (duration of <1 month), subacute (duration of 1-3 months), and chronic (duration of >3 months) pain. The recommendations do not apply to pain related to sickle cell disease or cancer or to patients receiving palliative or end-of-life care. The guideline addresses the following four areas: 1) determining whether or not to initiate opioids for pain, 2) selecting opioids and determining opioid dosages, 3) deciding duration of initial opioid prescription and conducting follow-up, and 4) assessing risk and addressing potential harms of opioid use. CDC developed the guideline using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. Recommendations are based on systematic reviews of the scientific evidence and reflect considerations of benefits and harms, patient and clinician values and preferences, and resource allocation. CDC obtained input from the Board of Scientific Counselors of the National Center for Injury Prevention and Control (a federally chartered advisory committee), the public, and peer reviewers. CDC recommends that persons with pain receive appropriate pain treatment, with careful consideration of the benefits and risks of all treatment options in the context of the patient's circumstances. Recommendations should not be applied as inflexible standards of care across patient populations. This clinical practice guideline is intended to improve communication between clinicians and patients about the benefits and risks of pain treatments, including opioid therapy; improve the effectiveness and safety of pain treatment; mitigate pain; improve function and quality of life for patients with pain; and reduce risks associated with opioid pain therapy, including opioid use disorder, overdose, and death. |
Prescribing opioids for pain - The New CDC Clinical Practice Guideline
Dowell D , Ragan KR , Jones CM , Baldwin GT , Chou R . N Engl J Med 2022 387 (22) 2011-2013 Pain affects the lives of millions of Americans and potentially reduces their level of function, mental health, and quality of life. Yet limited access to pain treatments and lack of clarity regarding the evidence supporting pain treatments prevent many people with pain from accessing the full range of potentially helpful therapies.1 Furthermore, there are persistent disparities in pain management according to race or ethnic group, gender, socioeconomic status, and population density, among other factors.2 Opioids continue to be commonly used to treat pain, despite evidence that their short-term benefits are small and despite limited evidence of long-term benefits.2,3 |
Concurrent Naloxone Dispensing Among Individuals with High-Risk Opioid Prescriptions, USA, 20152019
Guy GPJr , Strahan AE , Haegerich T , Losby JL , Ragan K , Evans ME , Jones CM . J Gen Intern Med 2021 36 (10) 3254-3256 In 2019, 49,860 drug overdose deaths in the USA involved opioids.1 Naloxone can reverse the effects of an opioid overdose. While the CDC Guideline for Prescribing Opioids for Chronic Pain recommends that clinicians consider prescribing naloxone when factors that increase risk for opioid overdose are present, such as higher opioid dosages and the use of both opioid and benzodiazepines,2 the extent of concurrent naloxone dispensing among this population is unknown. Previous research, limited to Medicare beneficiaries, indicated that very few patients received concurrent naloxone prescriptions.3 Similarly, naloxone prescriptions dispensed from retail pharmacies remain low.4 We examine concurrent naloxone dispensing among individuals with high-risk opioid prescriptions in the USA from 2015 to 2019. |
The context of sunburn among U.S. adults: Common activities and sun protection behaviors
Holman DM , Ragan KR , Julian AK , Perna FM . Am J Prev Med 2021 60 (5) e213-e220 INTRODUCTION: Sunburn increases skin cancer risk and is common among U.S. adults. However, little is known about the contexts in which sunburns often occur. The purpose of this study is to examine the contextual factors surrounding sunburns among U.S. adults. METHODS: Cross-sectional data from a 2018 online panel survey were analyzed. A total of 4,088 panel members were recruited by mail using probability-based, random sampling by address. Respondents were asked about their most recent sunburn, and analyses were limited to those who remembered their most recent sunburn (N=3,106). Data were weighted to match the U.S. Current Population Survey proportions; analyses were conducted in 2018 and 2019. RESULTS: Participants' age ranged from 18 to 93 years. About half (50.8%) were women, and most (82.3%) were non-Hispanic White adults. Swimming or spending time in water (32.5%), working outside at home (26.2%), traveling/vacationing (20.7%), and engaging in nonswimming physical activity (14.2%) were the most frequently reported activities. Using sunscreen on the face, neck, and chest (38.8%) and on the body (19.9%) and wearing sunglasses (34.2%) were the most frequently reported sun safety behaviors. Wearing clothes to the ankles (6.6%) and a long-sleeved shirt (4.5%) were least frequently reported. CONCLUSIONS: This study provides new information about the contexts in which adult sunburns often occur, especially about contexts unrelated to intentional tanning, which was relatively infrequent. The results suggest the need to promote multiple forms of sun protection tailored to specific outdoor activities and develop innovative solutions for outdoor physical and aquatic activities, which present unique sun safety challenges. |
Over the limit: tuberculosis and excessive alcohol use
Chaulk CP , Moonan PK . Int J Tuberc Lung Dis 2020 24 (1) 3-4 THE RELATIONSHIP BETWEEN alcohol consumption and tuberculosis (TB) is well documented.1 In 2017, 17% of all newly reported TB cases and 15% of all deaths during anti-tuberculosis treatment in the world were attributed to excessive alcohol use, second only to smoking (23%) as the top modifiable risk factor for TB.2 In this issue of the IJTLD, Ragan et al. conducted a comprehensive meta-analysis and found an association between excessive alcohol use and unsuccessful TB treatment outcomes.3 Among 111 studies analyzed, excessive alcohol use resulted in more loss to follow-up, more treatment failure, and more death than non-excessive alcohol use in both drug-susceptible and multidrug-resistant TB patients. |
Smoking cessation behaviors among older U.S. adults
Henley SJ , Asman K , Momin B , Gallaway MS , Culp MB , Ragan KR , Richards TB , Babb S . Prev Med Rep 2019 16 100978 Smoking cessation is a critical component of cancer prevention among older adults (age ≥ 65 years). Understanding smoking cessation behaviors among older adults can inform clinical and community efforts to increase successful cessation. We provide current, national prevalence estimates for smoking cessation behaviors among older adults, including interest in quitting, quitting attempts, quitting successes, receiving advice to quit from a healthcare provider, and use of evidence-based tobacco cessation treatments. The 2015 National Health Interview Survey and Cancer Control Supplement were used to estimate cigarette smoking status and cessation behaviors among older US adults across selected socio-demographic and health characteristics. We found that four in five older adults who had ever smoked cigarettes had quit and more than half who currently smoked were interested in quitting but fewer than half made a past-year quit attempt. Two-thirds of older adults said that a healthcare provider advised them to quit smoking, but just over one-third who tried to quit used evidence-based tobacco cessation treatments and only one in 20 successfully quit in the past year. Prevalence estimates for smoking cessation behaviors were similar across most characteristics. Our study demonstrates that few older adults, across most levels of characteristics examined, successfully quit smoking, underscoring the importance of assisting smoking cessation efforts. Healthcare providers can help older adults quit smoking by offering or referring evidence-based cessation treatments. States and communities can implement population-based interventions including tobacco price increases, comprehensive smoke-free policies, high-impact tobacco education media campaigns, and barrier-free access to evidence-based tobacco cessation counseling and medications. |
Skin cancer prevention behaviors among agricultural and construction workers in the United States, 2015
Ragan KR , Buchanan Lunsford N , Thomas CC , Tai EW , Sussell A , Holman DM . Prev Chronic Dis 2019 16 E15 INTRODUCTION: Nearly 5 million people are treated for skin cancer each year in the United States. Agricultural and construction workers (ACWs) may be at increased risk for skin cancer because of high levels of ultraviolet radiation exposure from the sun. This is the first study that uses nationally representative data to assess sun-protection behaviors among ACWs. METHODS: We analyzed data from the 2015 National Health Interview Survey Cancer Control Supplement to examine the prevalence of sun-protection behaviors among ACWs. We calculated national, weighted, self-reported prevalence estimates. We used chi(2) tests to assess differences between ACWs by industry and occupation. RESULTS: Most of the 2,298 agricultural and construction workers studied were male (by industry, 72.4% in agriculture and 89.3% in construction; by occupation, 66.1% in agriculture and 95.6% in construction) and non-Hispanic white. About one-third had at least 1 sunburn in the past year. The prevalence of sunscreen use and shade seeking was low and did not significantly differ among groups, ranging from 15.1% to 21.4% for sunscreen use and 24.5% to 29.1% for shade seeking. The prevalence of wearing protective clothing was significantly higher among agricultural workers than among construction workers by industry (70.9% vs 50.7%) and occupation (70.5% vs 53.0%). CONCLUSION: Our findings could be used to improve occupational health approaches to reducing skin cancer risk among ACWs and to inform education and prevention initiatives addressing skin cancer. Sun-safety initiatives may include modifying work sites to increase shade and adding sun safety to workplace policies and training. Employers can help reduce occupational health inequities and protect workers by creating workplaces that facilitate sun protection. |
Smoking cessation attitudes and practices among cancer survivors - United States, 2015
Gallaway MS , Glover-Kudon R , Momin B , Puckett M , Lunsford NB , Ragan KR , Rohan EA , Babb S . J Cancer Surviv 2019 13 (1) 66-74 PURPOSE: The prevalence of smoking among cancer survivors is similar to the general population. However, there is little evidence on the prevalence of specific smoking cessation behaviors among adult cancer survivors. METHODS: The 2015 National Health Interview Survey (NHIS) data were analyzed to examine the prevalence of smoking cessation behaviors and use of treatments among cancer survivors. Weighted self-reported prevalence estimates and 95% confidence intervals were calculated using a sample of 2527 cancer survivors. RESULTS: Among this sample of US cancer survivors, 12% were current smokers, 37% were former smokers, and 51% were never smokers. Compared with former and never smokers, current smokers were younger (< 65 years), less educated, and less likely to report being insured or Medicaid health insurance (p < 0.01). More males were former smokers than current or never smokers. Current smokers reported wanting to quit (57%), a past year quit attempt (49%), or a health professional advised them to quit (66%). Current smokers reported the use of smoking cessation counseling (8%) or medication (38%). CONCLUSIONS: Even after a cancer diagnosis, about one in eight cancer survivors continued to smoke. All could have received advice to quit smoking by a health professional, but a third did not. IMPLICATIONS FOR CANCER SURVIVORS: Health professionals could consistently advise cancer survivors about the increased risks associated with continued smoking, provide them with cessation counseling and medications, refer them to other free cessation resources, and inform them of cessation treatments covered by their health insurance. |
Circumstances of suicide among individuals with a history of cancer
Massetti GM , Holland KM , Jack SPD , Ragan KR , Lunsford NB . Psychooncology 2018 27 (7) 1750-1756 OBJECTIVE: Cancer can trigger psychological distress, which may be associated with risk of suicide. We explored precipitating circumstances of suicides among decedents with and without a history of cancer. METHODS: Coroner or medical examiner and law enforcement narratives of adult suicides were coded from 17 participating states in Centers for Disease Control and Prevention's National Violent Death Reporting System during 2004 to 2013. Bivariate and multivariate analyses examined associations between cancer history and factors that precipitated suicide. RESULTS: Of 90 581 suicides, 4182 decedents (4.6%) had a history of cancer. Significantly more decedents with a history of cancer (versus without) were male, non-Hispanic white, married, veterans, and aged 55 or older (P < .001). Decedents with a history of cancer were more likely to die of suicide by firearm and less likely to die of suicide by suffocation compared to poisoning. In matched case analyses controlling for demographic and recent circumstances, fewer decedents with a history of cancer had mental health problems, history of suicide attempts, alcohol use problems, intimate partner problems, financial problems, job problems, and recent crisis. CONCLUSIONS: Findings highlight the potential to identify high-risk populations for suicide prevention in clinical practice. |
Mental health problems and cancer risk factors among young adults
Massetti GM , Thomas CC , King J , Ragan K , Buchanan Lunsford N . Am J Prev Med 2017 53 S30-s39 INTRODUCTION: Chronic mental health problems often emerge in young adulthood, when adults begin to develop lifelong health behaviors and access preventive health services. The associations between mental health problems and modifiable cancer risk factors in young adulthood are not well understood. METHODS: In 2016, the authors analyzed 2014 Behavioral Risk Factor Surveillance System data on demographic characteristics, health service access and use, health status, and cancer risk factors (tobacco use, alcohol use, overweight or obesity, physical activity, and sleep) for 90,821 young adults aged 18-39 years with mental health problems (depressive disorder or frequent mental distress) compared to other young adults. RESULTS: Mental health problems were associated with white race; less than a high school education; lower income; being out of work or unable to work; being uninsured (for men only); poor health; previous diagnosis of asthma, skin cancer, or diabetes; and not having a recent checkup. After controlling for demographic characteristics, health service use, and health status, mental health problems among young adults were associated with smoking, binge drinking, inadequate sleep, having no leisure time physical activity, and being overweight or obese (among women only). Cervical cancer screening was not associated with mental health problems after controlling for demographic characteristics, health service use, and health status. CONCLUSIONS: Mental health problems in young adulthood were associated with potentially modifiable factors and behaviors that increase risk for cancer. Efforts to prevent cancer and promote health must attend to mental health disparities to meet the needs of young adults. |
Perspectives of screening-eligible women and male partners on benefits of and barriers to treatment for precancerous lesions and cervical cancer in Kenya
Ragan KR , Buchanan Lunsford N , Lee Smith J , Saraiya M , Aketch M . Oncologist 2017 23 (1) 35-43 BACKGROUND: Cervical cancer is the leading cause of female cancer mortality in Kenya. Kenya's National Cervical Cancer Prevention Program Strategic Plan outlines efforts to reduce the burden; however, treatment services remain limited. This study identified male and female perspectives regarding benefits, facilitators, and barriers to treatment for precancerous lesions and cervical cancer. MATERIALS AND METHODS: Ten focus groups were conducted in Nairobi and Nyanza in 2014 with females aged 25-49 years (n = 60) and male partners (n = 40). Participants were divided into groups dependent on screening status, sex, language, and geographic location. Qualitative analytic software was used to analyze transcribed and translated data. RESULTS: Treatment was endorsed as beneficial for the prevention of death and the improvement of wellness, quality of life, symptoms, and family life. Barriers reported by males and females included the following: (a) concerns about side effects; (b) treatment-related fear and stigma; (c) marital discord; (d) financial and access issues; (e) religious and cultural beliefs; and (f) limited knowledge. Male endorsement of wanting to improve knowledge and communication with their partners, in spite of stigmatizing beliefs and misperceptions regarding females with abnormal screening results or those who have been diagnosed with cancer, was novel. CONCLUSION: Incorporating qualitative data on benefits of and barriers to treatment for precancerous lesions and cervical cancer into Kenya's national priorities and activities is important. Our findings can be used to inform the development and successful implementation of targeted, region-specific community outreach and health messaging campaigns focused on alleviating the country's cervical cancer burden. IMPLICATIONS FOR PRACTICE: This article provides important insight into female and male partner perspectives regarding benefits, facilitators, and barriers to treatment for precancerous lesions and cervical cancer. Our novel research findings can inform the development of targeted community health interventions, educational messages, and resources and aid stakeholders in strengthening strategic plans regarding treatment coverage and cervical cancer prevention. Because several treatment barriers identified in this study are similar to barriers associated with cervical cancer screening in low- and middle-resourced countries, effective messaging interventions could address barriers to receipt of both screening and treatment. |
Missed opportunities for catch-up human papillomavirus vaccination among university undergraduates: Identifying health decision-making behaviors and uptake barriers
Ragan KR , Bednarczyk RA , Butler SM , Omer SB . Vaccine 2017 36 (2) 331-341 BACKGROUND: Suboptimal adolescent human papillomavirus (HPV) vaccine rates in the US highlight the need for catch-up vaccination. When teenagers enter college, there may be a shift in healthcare decision-making from parents and guardians to the students themselves. Little is known about factors influencing college students' healthcare decision-making processes. STUDY DESIGN: We evaluated HPV vaccine decision-making among 18-to-26-year-old college students through a self-administered, anonymous, cross-sectional survey. This survey was distributed to a sample of men and women in classroom settings at two universities. Categorical data comparisons were conducted using Chi-square and Fisher's exact tests. Multivariate Poisson regression was used to model initiation of HPV vaccine and compute prevalence ratios while controlling for key influential covariates at the 0.05 alpha level. RESULTS: A total of 527 students participated (response proportion=93.1%). Overall, 55.8% of participants received the HPV vaccine. Encouraging conversations with doctors and/or parents/guardians were identified as one of the most influential factors to increase vaccine uptake. Among students who received encouragement from both a doctor and parent, 95.8% received the vaccine. Campaigns about cancer prevention were viewed as more influential than those that focus on preventing genital warts. Approximately one-third of students indicated they didn't know where to get the HPV vaccine. Women were more likely to report that their parents would not let them get the HPV vaccine compared to men (26.7% vs. 2.3%). The majority of students (77.3%) indicated their parents were sometimes, equally, or mostly involved in making decisions about receiving vaccines (other than flu). CONCLUSION: Students' decision-making is greatly influenced by their parents; therefore, interventions for this population should work to increase students' control over decision-making while also addressing parental concerns. |
Environmental and psychosocial barriers to and benefits of cervical cancer screening in Kenya
Buchanan Lunsford N , Ragan K , Lee Smith J , Saraiya M , Aketch M . Oncologist 2017 22 (2) 173-181 BACKGROUND: Cervical cancer is the second most commonly diagnosed cancer in females and is a leading cause of cancer-related mortality in Kenya; limited cervical cancer screening services may be a factor. Few studies have examined men's and women's perceptions on environmental and psychosocial barriers and benefits related to screening. MATERIALS AND METHODS: In 2014, 60 women aged 25-49 years and 40 male partners participated in 10 focus groups (6 female and 4 male), in both rural and urban settings (Nairobi and Nyanza, Kenya), to explore perceptions about barriers to and benefits of cervical cancer screening. Focus groups were segmented by sex, language, geographic location, and screening status. Data were transcribed, translated into English, and analyzed by using qualitative software. RESULTS: Participants identified screening as beneficial for initiating provider discussions about cancer but did not report it as a beneficial method for detecting precancers. Perceived screening barriers included access (transportation, cost), spousal approval, stigma, embarrassment during screening, concerns about speculum use causing infertility, fear of residual effects of test results, lack of knowledge, and religious or cultural beliefs. All participants reported concerns with having a male doctor perform screening tests; however, men uniquely reported the young age of a doctor as a barrier. CONCLUSION: Identifying perceived barriers and benefits among people in low- and middle-income countries is important to successfully implementing emerging screening programs. The novel findings on barriers and benefits from this study can inform the development of targeted community outreach activities, communication strategies, and educational messages for patients, families, and providers. Implications for Practice: This article provides important information for stakeholders in clinical practice and research when assessing knowledge, beliefs, and acceptability of cervical cancer screening and treatment services in low- and middle-resourced countries. Formative research findings provide information that could be used in the development of health interventions, community education messages, and materials. Additionally, this study illuminates the importance of understanding psychosocial barriers and facilitators to cervical cancer screening, community education, and reduction of stigma as important methods of improving prevention programs and increasing rates of screening among women. |
Disparities in the context of opportunities for cancer prevention in early life
Massetti GM , Thomas CC , Ragan KR . Pediatrics 2016 138 S65-s77 Persistent health disparities are a major contributor to disproportionate burden of cancer for some populations. Health disparities in cancer incidence and mortality may reflect differences in exposures to risk factors early in life. Understanding the distribution of exposures to early life risk and protective factors for cancer across different populations can shed light on opportunities to promote health equity at earlier developmental stages. Disparities may differentially influence risk for cancer during early life and create opportunities to promote health equity. Potential risk and protective factors for cancer in early life reveal patterns of disparities in their exposure. These disparities in exposures can manifest in downstream disparities in risk for cancer. These risk and protective factors include adverse childhood experiences; maternal alcohol consumption in pregnancy; childhood obesity; high or low birth weight; benzene exposure; use of assisted reproductive technologies; pesticide and insecticide exposure; isolated cryptorchidism; early pubertal timing; exposure to radiation; exposure to tobacco in utero and in early life; allergies, asthma, and atopy; and early exposure to infection. Disparities on the basis of racial and ethnic minority status, economic disadvantage, disability status, sex, geography, and nation of origin can occur in these risk and protective factors. Vulnerable populations experience disproportionally greater exposure to risk factors in early life. Addressing disparities in risk factors in early life can advance opportunities for prevention, promote health equity, and possibly reduce risk for subsequent development of cancer. |
Antihypertensive medication adherence and blood pressure control among central Alabama veterans
Piercefield EW , Howard ME , Robinson MH , Kirk CE , Ragan AP , Reese SD . J Clin Hypertens (Greenwich) 2016 19 (5) 543-549 Medication nonadherence is associated with adverse outcomes. To evaluate antihypertensive medication adherence and its association with blood pressure (BP) control, the authors described population adherence to prescribed antihypertensive medication (proportion of days covered ≥80%) and BP control (mean BP <140/90 mm Hg) among central Alabama veterans during the fiscal year 2015. Overall, 75.1% of patients receiving antihypertensive medication were considered adherent, and 66.1% had adequate BP control. Patients adherent to antihypertensive medication were more likely to have adequate BP control compared with patients classified as nonadherent (67.4% vs 62.0%; adjusted odds ratio 1.33; 95% confidence interval, 1.22-1.44 [P<.0001]). Among patients who had uncontrolled BP, 73.6% were considered adherent to medication. Adherence to antihypertensive medication was associated with adequate BP control; however, a substantial proportion of patients with inadequate BP control were also considered adherent. Interventions to increase BP control could address more aggressive medication management to achieve BP goals. |
Public health opportunities for promoting health equity in cancer prevention and control in LGBT populations
Massetti GM , Ragan KR , Thomas CC , Ryerson AB . LGBT Health 2015 11-14 Advances in cancer prevention, detection, and treatment have led to reductions in morbidity and premature mortality and improvements in quality of life. However, not all Americans have benefitted equally from these advances, and certain populations experience continued disparities in cancer care. Although research and public health efforts have highlighted the experiences of some groups, other populations have been relatively understudied, such as lesbian, gay, bisexual, and transgender (LGBT) individuals. Public health efforts in surveillance, research, programs, and partnerships can provide opportunities to advance health equity for LGBT at the population level and lead to better health outcomes for LGBT individuals with cancer. |
Hospitalized patients with 2009 pandemic influenza A (H1N1) virus infection in the United States - September-October 2009
Skarbinski J , Jain S , Bramley A , Lee EJ , Huang J , Kirschke D , Stone A , Wedlake T , Richards SM , Page S , Ragan P , Bullion L , Neises D , Williams RM , Petruccelli BP , Vandermeer M , Lofy KH , Gindler J , Finelli L . Clin Infect Dis 2011 52 S50-S59 Given the potential worsening clinical severity of 2009 pandemic influenza A (H1N1) virus (pH1N1) infection from spring to fall 2009, we conducted a clinical case series among patients hospitalized with pH1N1 infection from September through October 2009. A case patient was defined as a hospitalized person who had test results positive for pH1N1 virus by real-time reverse-transcription polymerase chain reaction. Among 255 hospitalized patients, 34% were admitted to an intensive care unit and 8% died. Thirty-four percent of patients were children 18 years of age, 8% were adults ≥65 years of age, and 67% had an underlying medical condition. Chest radiographs obtained at hospital admission that had findings that were consistent with pneumonia were noted in 103 (46%) of 255 patients. Among 255 hospitalized patients, 208 (82%) received neuraminidase inhibitors, but only 47% had treatment started ≤2 days after illness onset. Overall, characteristics of hospitalized patients with pH1N1 infection in fall 2009 were similar to characteristics of patients hospitalized with pH1N1 infection in spring 2009, which suggests that clinical severity did not change substantially over this period. |
Healthcare-associated hepatitis C virus transmission among patients in an abdominal organ transplant center
Thompson ND , Hellinger WC , Kay RS , Cohen L , Ragan P , Voss RA , Bacalis LP , Xia G , Keating MR , Dickson RC , Hughes CB , Williams IT , Perz JF . Transpl Infect Dis 2009 11 (4) 324-9 BACKGROUND: De novo hepatitis C virus (HCV) infection among transplant patients is rarely recognized but can have severe consequences. We investigated the scope, source, and mode of HCV transmission within a transplant center after incident HCV infection was identified in 2 patients who had liver transplantation in late 2006. METHODS: Patients were interviewed, and transplant logs, medical records, and staff practices were reviewed to identify opportunities for HCV transmission. Infection via receipt of blood or organs was evaluated. Molecular epidemiology was used to determine the relatedness between persons with incident and chronic HCV infection. RESULTS: HCV from infected blood or organ donors was ruled out. Among the 308 patients who underwent transplant in 2006, no additional incident HCV infections were identified. Eighty-five (28%) had pre-transplant chronic HCV infection; 13 were considered possible HCV source patients based upon shared days on the inpatient unit, nursing assignment, or invasive procedures in common with incident HCV case-patients. Viral isolates from 1 HCV source patient and 1 incident case-patient were found to be highly related by quasispecies analysis, confirming patient-to-patient HCV transmission. Possible modes of transmission identified were the improper use of multidose vials, sharing of blood-contaminated glucometers, and touch contamination. CONCLUSION: Sporadic transmission or endemic levels of HCV transmission might be overlooked in a setting with high HCV prevalence, such as liver transplant units, where multiple, repeated opportunities for patient-to-patient HCV transmission can occur. Surveillance through pre- and post-transplant screening is necessary to identify incident HCV infection in this setting. Constant, meticulous attention must be paid to maintaining aseptic technique and good infection control practices to eliminate HCV transmission opportunities. |
