Evidence-Based Identification of Key Beliefs Explaining Infant Male Circumcision Motivation Among Expectant Parents in Zimbabwe: Targets for Behavior Change Messaging.

Slow adult male circumcision uptake is one factor leading some to recommend increased priority for infant male circumcision (IMC) in sub-Saharan African countries. This research, guided by the integrated behavioral model (IBM), was carried out to identify key beliefs that best explain Zimbabwean parents' motivation to have their infant sons circumcised. A quantitative survey, designed from qualitative elicitation study results, was administered to independent representative samples of 800 expectant mothers and 795 expectant fathers in two urban and two rural areas in Zimbabwe. Multiple regression analyses found IMC motivation among fathers was explained by instrumental attitude, descriptive norm and self-efficacy; while motivation among mothers was explained by instrumental attitude, injunctive norm, descriptive norm, self-efficacy, and perceived control. Regression analyses of beliefs underlying IBM constructs found some overlap but many differences in key beliefs explaining IMC motivation among mothers and fathers. We found differences in key beliefs among urban and rural parents. Urban fathers' IMC motivation was explained best by behavioral beliefs, while rural fathers' motivation was explained by both behavioral and efficacy beliefs. Urban mothers' IMC motivation was explained primarily by behavioral and normative beliefs, while rural mothers' motivation was explained mostly by behavioral beliefs. The key beliefs we identified should serve as targets for developing messages to improve demand and maximize parent uptake as IMC programs are rolled out. These targets need to be different among urban and rural expectant mothers and fathers.

Identification of Key Beliefs Explaining Male Circumcision Motivation Among Adolescent Boys in Zimbabwe: Targets for Behavior Change Communication.

Male circumcision (MC) significantly reduces HIV acquisition among men, leading WHO/UNAIDS to recommend high HIV and low MC prevalence countries circumcise 80% of adolescents and men age 15-49. Despite significant investment to increase MC capacity only 27% of the goal has been achieved in Zimbabwe. To increase adoption, research to create evidence-based messages is greatly needed. The Integrated Behavioral Model (IBM) was used to investigate factors affecting MC motivation among adolescents. Based on qualitative elicitation study results a survey was designed and administered to a representative sample of 802 adolescent boys aged 13-17 in two urban and two rural areas in Zimbabwe. Multiple regression analysis found all six IBM constructs (2 attitude, 2 social influence, 2 personal agency) significantly explained MC intention (R2 = 0.55). Stepwise regression analysis of beliefs underlying each IBM belief-based construct found 9 behavioral, 6 injunctive norm, 2 descriptive norm, 5 efficacy, and 8 control beliefs significantly explained MC intention. A final stepwise regression of all the significant IBM construct beliefs identified 12 key beliefs best explaining intention. Similar analyses were carried out with subgroups of adolescents by urban-rural and age. Different sets of behavioral, normative, efficacy, and control beliefs were significant for each sub-group. This study demonstrates the application of theory-driven research to identify evidence-based targets for the design of effective MC messages for interventions to increase adolescents' motivation. Incorporating these findings into communication campaigns is likely to improve demand for MC.

A Phase II Randomized Controlled Trial Comparing Safety, Procedure Time, and Cost of the PrePex™ Device to Forceps Guided Surgical Circumcision in Zimbabwe.

BACKGROUND: The World Health Organization (WHO) and the Joint United Nations Program on HIV/AIDS promote MC (male circumcision) as a key HIV prevention strategy where HIV prevalence and incidence are high and MC prevalence is low. In Zimbabwe, to achieve the 1.26 million circumcisions needed to be performed by 2015 to achieve optimal MC coverage, a new approach was needed. The primary objective of the current trial was to assess the performance (safety, procedure time, and cost) of the PrePex device compared to forceps-guided surgical circumcision. METHODS AND FINDINGS: This Phase II, randomized, open-label trial in Zimbabwe involved healthy, non-circumcised adult male volunteers who were randomly assigned to the PrePex device (n = 160) or surgical arm (n = 80). Three doctors and 4 nurses, all certified on both circumcision methods, performed the procedures. The PrePex device procedure involves a plastic ring with a rubber O-ring that necrotizes the foreskin to facilitate easy and minimally invasive removal. Total procedure time was the primary endpoint. Adverse event (AE) data were also gathered for 90 days post-procedure. All 80 participants in the surgical arm and 158 participants in the PrePex arm achieved complete circumcision. The total procedure time for the PrePex device was approximately one-third of the total surgical procedure (4.8 minutes, Standard Deviation [SD]: 1.2 versus 14.6 minutes; SD: 4.2; p<0.00001). There were 2 AEs for 2 participants (rate of 1.3%, 95% Confidence Interval: 0.0025-4.53%), which were resolved with simple intervention. The AEs were device related, including 1 case of pain leading to device removal and 1 case of removal of the device. CONCLUSIONS: The trial supports previous studies' conclusions that the PrePex procedure is safe, quick, easy to apply, and effective in terms of procedure time as an alternative to traditional surgical circumcision. The PrePex device has great potential for use in overburdened health systems and in resource-limited settings and is recommended for use in rapid scale-up of adult MC in Zimbabwe. TRIAL REGISTRATION: ClinicalTrials.gov NCT01956370.

Psychosocial Results from a Phase I Trial of a Nonsurgical Circumcision Device for Adult Men in Zimbabwe.

Male circumcision (MC), an effective HIV prevention tool, has been added to Zimbabwe's Ministry of Health and Child Care HIV/AIDS Prevention Program. A Phase I safety trial of a nonsurgical male circumcision device was conducted and extensive psychosocial variables were assessed. Fifty-three men (18 and older) were recruited for the device procedure; 13 follow-up clinical visits were completed. Interviews conducted three times (before the procedure, at 2 weeks and 90 days post-procedure) assessed: Satisfaction; expectations; actual experience; activities of daily living; sexual behavior; and HIV risk perception. Using the Integrated Behavioral Model, attitudes towards MC, sex, and condoms, and sources of social influence and support were also assessed. Men (mean age 32.5, range 18-50; mean years of education = 13.6; 55% employed) were satisfied with device circumcision results. Men understand that MC is only partially protective against HIV acquisition. Most (94.7%) agreed that they will continue to use condoms to protect themselves from HIV. Pain ratings were surprisingly negative for a procedure billed as painless. Men talked to many social networks members about their MC experience; post-procedure (mean of 14 individuals). Minimal impact on activities of daily living and absenteeism indicate possible cost savings of device circumcisions. Spontaneous erections occurred frequently post-procedure. The results had important implications for changes in the pre-procedure clinical counseling protocol. Clear-cut counseling to manage pain and erection expectations should result in improved psychosocial outcomes in future roll-out of device circumcisions. Men's expectations must be managed through evidence-based counseling, as they share their experiences broadly among their social networks.

Evidence-based identification of key beliefs explaining adult male circumcision motivation in Zimbabwe: targets for behavior change messaging.

Male circumcision (MC) reduces HIV acquisition among men, leading WHO/UNAIDS to recommend a goal to circumcise 80 % of men in high HIV prevalence countries. Significant investment to increase MC capacity in priority countries was made, yet only 5 % of the goal has been achieved in Zimbabwe. The integrated behavioral model (IBM) was used as a framework to investigate the factors affecting MC motivation among men in Zimbabwe. A survey instrument was designed based on elicitation study results, and administered to a representative household-based sample of 1,201 men aged 18-30 from two urban and two rural areas in Zimbabwe. Multiple regression analysis found all five IBM constructs significantly explained MC Intention. Nearly all beliefs underlying the IBM constructs were significantly correlated with MC Intention. Stepwise regression analysis of beliefs underlying each construct respectively found that 13 behavioral beliefs, 5 normative beliefs, 4 descriptive norm beliefs, 6 efficacy beliefs, and 10 control beliefs were significant in explaining MC Intention. A final stepwise regression of the five sets of significant IBM construct beliefs identified 14 key beliefs that best explain Intention. Similar analyses were carried out with subgroups of men by urban-rural and age. Different sets of behavioral, normative, efficacy, and control beliefs were significant for each sub-group, suggesting communication messages need to be targeted to be most effective for sub-groups. Implications for the design of effective MC demand creation messages are discussed. This study demonstrates the application of theory-driven research to identify evidence-based targets for intervention messages to increase men's motivation to get circumcised and thereby improve demand for male circumcision.

Concurrent partnerships, acute infection and HIV epidemic dynamics among young adults in Zimbabwe.

This paper explores the roles of acute infection and concurrent partnerships in HIV transmission dynamics among young adults in Zimbabwe using realistic representations of the partnership network and all published estimates of stage-specific infectivity. We use dynamic exponential random graph models to estimate partnership network parameters from an empirical study of sexual behavior and drive a stochastic simulation of HIV transmission through this dynamic network. Our simulated networks match observed frequencies and durations of short- and long-term partnerships, with concurrency patterns specific to gender and partnership type. Our findings suggest that, at current behavior levels, the epidemic cannot be sustained in this population without both concurrency and acute infection; removing either brings transmission below the threshold for persistence. With both present, we estimate 20-25% of transmissions stem from acute-stage infections, 30-50% from chronic-stage, and 30-45% from AIDS-stage. The impact of acute infection is strongly moderated by concurrency. Reducing this impact by reducing concurrency could potentially end the current HIV epidemic in Zimbabwe.

Colorectal cancer screening use among insured primary care patients.

OBJECTIVE: To compare colorectal cancer (CRC) screening use, including changes over time and demographic characteristics associated with screening receipt, between 2 insured primary care populations. STUDY DESIGN: Clinical and administrative records from 2 large health systems, one in New Mexico and the other in Michigan, were used to determine use of CRC screening tests between 2004 and 2008 among patients aged 51 to 74 years. METHODS: Generalized estimating equations were used to evaluate trends in CRC screening use over time and the association of demographic and other factors with screening receipt. RESULTS: Rates of CRC screening use ranged from 48.1% at the New Mexico site to 68.7% at the Michigan site, with colonoscopy being the most frequently used modality. Fecal occult blood test was used inconsistently by substantial proportions of patients who did not meet the definition of screening users. Screening use was positively and significantly associated with older age, male sex, and more periodic health examinations and other types of primary care visits; at the Michigan site, it was also associated with African American race, married status, and higher annual estimated household income. CONCLUSIONS: Among insured primary care patients, CRC screening use falls short. Further research is needed to determine what factors are barriers to routine fecal occult blood test or colonoscopy use among insured patients who have access to and regularly use primary care and how those barriers can be eliminated.

STD/HIV prevention practices among primary care clinicians: risk assessment, prevention counseling, and testing.

OBJECTIVE: To describe current practices of primary care (PC) clinicians for STD/HIV control services: risk assessment, prevention counseling, and offering tests. STUDY DESIGN: We identified clinical strategies through qualitative interviews. We then surveyed by mail a random sample of Washington State family physicians, general internists, obstetrician-gynecologists, nurse practitioners, and certified nurse midwives. We identified characteristics of clinicians and their practices associated with each strategy and universal provision of each service. RESULTS: We report on 519 clinicians (80% adjusted response rate). Clinicians provided services to selected patients they considered high risk. Universal practices were less common: risk assessment (56%), prevention counseling (60%), STD tests (30%), and HIV tests (19%). Universal services were more common among nurses, those recently trained, and those seeing more STD patients. CONCLUSION: Different types of PC clinicians use widely differing clinical strategies and many use selective rather than universal approaches to STD/HIV control services. Further research is needed to develop tailored interventions to improve provision of these services.

Cervical cancer screening and management practices among providers in the National Breast and Cervical Cancer Early Detection Program (NBCCEDP).

BACKGROUND: This study was conducted to describe clinicians serving women in the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) with regard to demographic and practice characteristics and their usual practices in cervical cancer screening and abnormal cytology management, as well as human papillomavirus (HPV) test use. METHODS: The authors analyzed data from a nationally representative survey conducted in 2004 of providers practicing 7 specialties that commonly offer cervical cancer screening. The program providers were compared with nonprogram providers. RESULTS: Program providers were found to be significantly more likely than nonprogram providers to be midlevel providers and to serve low-income, racial/ethnic minorities who are insured by Medicaid. In addition, they had significantly more patients with abnormal Papanicolaou tests and were more likely to offer onsite colposcopy (57% vs 40%). Program providers were less likely to use liquid-based cytology (LBC) as their sole method for cytology. Approximately 20% of program and nonprogram providers used HPV DNA testing as an adjunct to screening cytology and two-thirds used HPV tests to manage patients with abnormal cytology results. However, many also used HPV testing for reasons not approved by the U.S. Food and Drug Administration (FDA), such as for screening women age <30 years. CONCLUSIONS: As of mid-2004, program providers served racially and ethnically diverse, low-income patients who are at high risk for cervical cancer compared with nonprogram providers, as intended by this program. Because many providers offered on-site colposcopy, used LBC, and used HPV tests for patients with abnormal cytology results, they are well equipped to reduce the risk of cervical cancer. Many program providers used the HPV test for reasons that were not approved of by the FDA or reimbursed by the NBCCEDP. The results of this survey have informed training materials for program providers, reimbursement policies for LBC and HPV tests, and interventions to discourage inappropriate HPV testing.

Anogenital warts knowledge and counseling practices of US clinicians: results from a national survey.

OBJECTIVES: To examine messages US clinicians use when counseling patients diagnosed with anogenital warts. STUDY DESIGN: In mid-2004, we conducted a confidential mail survey of nationally representative samples of physicians practicing internal and adolescent medicine, family/general practice, obstetrics/gynecology, urology, or dermatology; nurse midwives; physician assistants; and nurse practitioners. The survey assessed knowledge and counseling practices of clinicians who had diagnosed anogenital warts. RESULTS: After adjusting for survey eligibility, 81% responded. Most (89%) were aware that human papillomavirus (HPV) causes anogenital warts, but only 48% were aware that oncogenic and wart-related HPV genotypes usually differ. Most (>95%) clinicians reported telling patients with warts that warts are an STD, are caused by a virus, or that their sex partners may have or may acquire warts. Many clinicians (>/=85%) also reported discussing STD prevention or assessing STD risk with such patients. Most reported addressing ways to prevent HPV (89%), including using condoms; limiting sex partners or practicing monogamy; or abstinence. Many also reported recommending prompt (82%) or more frequent (52%) Pap testing to female patients with anogenital warts. Potential barriers to counseling included providing definitive answers on how HPV infection was acquired, dealing with patients' psychosocial issues, and inadequate reimbursement. CONCLUSIONS: Most surveyed clinicians appropriately counseled patients about the cause and prevention of anogenital warts. However, many clinicians were unaware that oncogenic and wart-related HPV types usually differ, and this may explain why many reported recommending more aggressive cervical cancer screening for female patients with warts.

STD care: variations in clinical care associated with provider sex, patient sex, patients' self-reported symptoms or high-risk behaviors, partner STD history.

Sexually transmitted diseases in the United States are frequently diagnosed by private, as well as public, physicians. However, we know little about the decision processes that physicians employ when faced with people who may or may not be infected. To address this gap, we compared physicians' responses to different patient vignettes to assess how variations in patients' presentations affect physicians' clinical behavior. We systematically varied reported symptoms, behavioral risk, partner STD, and sex of patients in 16 different vignettes, with one vignette randomly presented to each physician in a national survey. Physicians rated the likelihood of 12 clinical management actions they might take with the patient vignette presented. Responses varied with self-reported symptoms, high-risk behavior, and report of an STD infected partner such that female physicians were more attentive to sexual health, and all physicians were more likely to treat female patients aggressively, relative to their male patients. Overall behavior was broadly congruent with sound medical practice, although we discuss several caveats to this general statement.

Acceptance of flexible sigmoidoscopy screening for colorectal cancer.

This study was conducted in the Kaiser Permanente Medical Care Program of Northern California to identify patient characteristics that explain interest in flexible sigmoidoscopy (FS) screening. A mailed screening invitation to 6837 age-eligible patients elicited responses from 49%. Efforts to reach and interview both eligible respondents and non-respondents resulted in 2728 computer-assisted telephone interviews (CATI), with 60% indicating interest in FS screening. Five components of the Integrated Behavioral Model were measured with respect to FS screening: attitude, affect, social influence, facilitators/barriers, and perceived risk of colorectal cancer. All five model components were significantly and independently associated with interest in FS, with patient attitude being the strongest predictor. Of the 32 items comprising the model components, nine items having the highest correlations with FS interest were identified as potentially important issues to address by efforts to increase interest in screening. Six of these were attitudinal beliefs. The findings from this theory-driven study provide specific targets for the design of interventions to increase FS interest and screening rates.

STD screening, testing, case reporting, and clinical and partner notification practices: a national survey of US physicians.

OBJECTIVES: This study presents results from a national survey of US physicians that assessed screening, case reporting, partner management, and clinical practices for syphilis, gonorrhea, chlamydia, and HIV infection. METHODS: Surveys were mailed to a random sample of 7300 physicians to assess screening, testing, reporting, and partner notification for syphilis, gonorrhea, chlamydia, and HIV. RESULTS: Fewer than one third of physicians routinely screened men or women (pregnant or nonpregnant) for STDs. Case reporting was lowest for chlamydia (37 percent), intermediate for gonorrhea (44 percent), and higher for syphilis, HIV, and AIDS (53 percent-57 percent). Physicians instructed patients to notify their partners (82 percent-89 percent) or the health department (25 percent-34 percent) rather than doing so themselves. CONCLUSIONS: STD screening levels are well below practice guidelines for women and virtually nonexistent for men. Case reporting levels are below those legally mandated; physicians rely instead on patients for partner notification. Health departments must increase collaboration with private physicians to improve the quality of STD care.

Sexually transmitted disease screening by United States obstetricians and gynecologists.

OBJECTIVE: To assess compliance with practice guidelines and to determine the extent of missed opportunities for sexually transmitted disease (STD) prevention by describing screening practices of a national sample of obstetricians and gynecologists and comparing them to the practices of other specialists. METHODS: Physicians (n = 7300) in five specialties that diagnose 85% of STDs in the United States were surveyed. Obstetrics and gynecology (n = 647) was one of the five specialties. Besides providing demographic and practice characteristics, respondents answered questions about who they screen (nonpregnant females, pregnant females) and for which bacterial STDs (syphilis, gonorrhea, chlamydia). RESULTS: Responding obstetricians and gynecologists were most likely to be non-Hispanic white (75%), male (66%), and in their 40s (mode 43 years old). They saw an average of 90 patients per week during 47 hours of direct patient care. Approximately 95% practiced in private settings. Almost all (96%) screened some patients for at least one STD. Obstetricians and gynecologists screened women more frequently than other specialties, but no specialty screened all women or all pregnant women. CONCLUSION: Obstetricians and gynecologists screen women for STDs at a higher rate than other specialties represented in this study. Consistent with published guidelines, most obstetricians and gynecologists in our survey screened pregnant women for chlamydia, gonorrhea, and syphilis. Nonetheless, only about half of obstetricians and gynecologists screened nonpregnant women for gonorrhea or chlamydia, and fewer screen nonpregnant women for syphilis.
