Cancer prevention in primary care: predictors of patient counseling across four risk behaviors over 24 months

Primary care Providers' approaches to cervical cancer screening in Muslim females

The utilization of the Papanicolaou (Pap) test and the human papillomavirus (HPV) vaccine has significantly decreased rates of cervical cancer and related mortality. Disparities in receiving these preventive screenings are scarcely studied in Muslim females. Our study explores primary care providers' (PCP) approaches to cervical cancer screening in Muslim females. We created a cross-sectional Qualtrics survey using convenience sampling of PCPs who perform Pap tests in central Ohio. Recruitment emails were disseminated via departmental email listservs. We had 200 analyzable responses and 78% of respondents reported having Muslim patients. Bivariate analysis was used to identify predictors of providers' approaches. Providers younger than 35 years obtained a sexual history from Muslim females less frequently, family medicine providers were more likely to obtain a sexual history from Muslim females, and gynecologists were more likely to offer the HPV vaccine to Muslim females. Providers who counseled patients about Pap tests (P<0.001) and HPV modes of transmission (P<0.004) were more likely to offer cervical cancer screening for Muslim females. Our findings suggested that providers' age and specialty may be predictors of proactive cervical cancer screening and prevention in Muslim females and that there is a gap between current guidelines and preventive clinical practices regarding the HPV vaccine and transmission counseling.

Lung Cancer Screening Policy in Alaska and Occupational Therapy

Lung cancer claims more lives than any other cancer in the world and remains difficult to diagnose in the early stages. This article examines the current state of lung cancer detection and screening via low-dose computed tomography (LDCT) in Alaska and considers potential opportunities for occupational therapy practitioners in primary care settings. Medicare requires at least one documented shared decision-making encounter between provider and patient before LDCT lung cancer screening occurs. As a result of time constraints, documentation requirements, and the plethora of preventive health services they provide, primary care physicians often lack the time and training to conduct this essential service. This provides an opportunity for occupational therapy practitioners to perform these services as part of their practice and to play a role in this area as patient educators and prevention specialists in primary care settings. What This Article Adds: This article explores the national health crisis of lung cancer and describes how occupational therapists can participate in providing care in primary care settings.

Photoprotection With Mineral-Based Sunscreens

BACKGROUND

Although chemical sunscreens have traditionally been at the forefront of sun protection, safety concerns and increasing awareness of the environmental impact of personal-care products have led to greater interest in the use of mineral blockers as photoprotective agents.

OBJECTIVE

To examine the safety and efficacy of mineral-based sunscreens to allow patients to make informed choices about ultraviolet (UV) protection.

MATERIALS AND METHODS

A review of the literature was performed using the PubMed database.

RESULTS

This article provides an overview of physical blockers and focuses on the efficacy of mineral sunscreens in offering broad-spectrum UV protection and safety concerns, including the controversy surrounding the use of nanoparticles. Practical tips for application are also reviewed.

CONCLUSION

Mineral sunscreens are an attractive, efficacious option for consumers who prefer alternative choices in sun protection.

Patient Knowledge of Sunscreen Guidelines and Frequency of Physician Counseling: A Cross-sectional Study

Background: Skin cancer and photodamage are problems commonly addressed by dermatologists. Despite the opportunities for chemoprevention with broad-spectrum sunscreen, there is little research investigating patient knowledge of proper sunscreen guidelines, or patient perception of physician counseling. Objective: The author sought to determine patient knowledge of the American Academy of Dermatology guidelines for proper sunscreen use and to obtain patient-reported rates of physician counseling regarding sunscreen. Design: We used a 12-question, multiple choice, anonymous survey to collect data. Setting: The study setting was a private dermatology clinic near Detroit, Michigan.

PARTICIPANTS

Two hundred ninety- four adult patients presenting for routine office visits were included in the study. Results: About 59 percent of the subjects selected the recommended frequency of proper sunscreen use and 60 percent selected the recommended minimum sun protection factor. The minimum amount of sunscreen to cover the body, time of application before sun exposure, and time between reapplications of sunscreen did not receive a majority response. Differences in knowledge were seen between the sexes and skin types. Forty-four percent of patients previously received sunscreen counseling. Patients older than 40 years of age (39.3% vs. 18.4%, p=0.04), those who were fair skinned (62.5% vs. 23.8%), established patients (40.7% vs. 8.3%, p <0.0001), and those with a skin cancer (58.3% vs. 28%, p<0.0001) were more likely to report previous counseling. Conclusions: The majority of the study subjects never received counseling and lacked adequate knowledge of sunscreen guidelines. In order to obtain adequate primary prevention of skin cancer, it is essential to provide patients with further counseling and education on proper sunscreen use.

Extending Theory-Based Quantitative Predictions to New Health Behaviors

BACKGROUND

Traditional null hypothesis significance testing suffers many limitations and is poorly adapted to theory testing.

PURPOSE

A proposed alternative approach, called Testing Theory-based Quantitative Predictions, uses effect size estimates and confidence intervals to directly test predictions based on theory.

METHOD

This paper replicates findings from previous smoking studies and extends the approach to diet and sun protection behaviors using baseline data from a Transtheoretical Model behavioral intervention (N = 5407). Effect size predictions were developed using two methods: (1) applying refined effect size estimates from previous smoking research or (2) using predictions developed by an expert panel.

RESULTS

Thirteen of 15 predictions were confirmed for smoking. For diet, 7 of 14 predictions were confirmed using smoking predictions and 6 of 16 using expert panel predictions. For sun protection, 3 of 11 predictions were confirmed using smoking predictions and 5 of 19 using expert panel predictions.

CONCLUSION

Expert panel predictions and smoking-based predictions poorly predicted effect sizes for diet and sun protection constructs. Future studies should aim to use previous empirical data to generate predictions whenever possible. The best results occur when there have been several iterations of predictions for a behavior, such as with smoking, demonstrating that expected values begin to converge on the population effect size. Overall, the study supports necessity in strengthening and revising theory with empirical data.

Effectiveness of individual-focused interventions to prevent chronic disease

BACKGROUND

The burden of chronic disease is projected to assume crisis proportions in most parts of the world by the middle of the century, focusing attention on the need for preventive interventions. We identify and review published research on primary prevention individual-level interventions in current practice and describe and discuss the limitations of the current evidence. The report facilitates prioritizing a research agenda for potential interventions that might be investigated within cohort studies.

MATERIALS AND METHODS

This study is a rapid review. Computerized database searches (PubMed and EMBASE) were performed in October 2012 to identify articles on primary prevention interventions that are directed at the individual level. Potentially, relevant International Agency of Research on Cancer handbooks and monographs were also reviewed. The review includes articles reported in English on the efficacy or effectiveness of a preventive intervention in an adult population. It excludes articles on alcohol or tobacco smoking.

RESULTS

Many chronic disease interventions directed at individuals report a protective effect in the short term and some evidence for the efficacy of chemoprevention in chronic disease prevention exists. Evidence these effects persist in the longer term is inconsistent.

CONCLUSIONS

There are currently only limited evidence-based preventions for most chronic diseases, for which a summary is available in Table A1 (see Appendix B). Most individual-level intervention research studies have been conducted using case-control designs and some small, randomized studies. There are fewer impediments to lifestyle modifications when compared to prevention using chemoprevention and vaccination or other methods of prevention of persistent infection.

The impact of a team-based intervention on the lifestyle risk factor management practices of community nurses: outcomes of the community nursing SNAP trial

BACKGROUND

Lifestyle risk factors like smoking, nutrition, alcohol consumption, and physical inactivity (SNAP) are the main behavioural risk factors for chronic disease. Primary health care is an appropriate setting to address these risk factors in individuals. Generalist community health nurses (GCHNs) are uniquely placed to provide lifestyle interventions as they see clients in their homes over a period of time. The aim of the paper is to examine the impact of a service-level intervention on the risk factor management practices of GCHNs.

METHODS

The trial used a quasi-experimental design involving four generalist community nursing services in NSW, Australia. The services were randomly allocated to either an intervention group or control group. Nurses in the intervention group were provided with training and support in the provision of brief lifestyle assessments and interventions. The control group provided usual care. A sample of 129 GCHNs completed surveys at baseline, 6 and 12 months to examine changes in their practices and levels of confidence related to the management of SNAP risk factors. Six semi-structured interviews and four focus groups were conducted among the intervention group to explore the feasibility of incorporating the intervention into everyday practice.

RESULTS

Nurses in the intervention group became more confident in assessment and intervention over the three time points compared to their control group peers. Nurses in the intervention group reported assessing physical activity, weight and nutrition more frequently, as well as providing more brief interventions for physical activity, weight management and smoking cessation. There was little change in referral rates except for an improvement in weight management related referrals. Nurses' perception of the importance of 'client and system-related' barriers to risk factor management diminished over time.

CONCLUSIONS

This study shows that the intervention was associated with positive changes in self-reported lifestyle risk factor management practices of GCHNs. Barriers to referral remained. The service model needs to be adapted to sustain these changes and enhance referral.

Receipt of preventive counseling among reproductive-aged women in rural and urban communities

INTRODUCTION

Preventive health interventions often occur less frequently among rural women compared to urban women. Preventive counseling is an important feature of comprehensive preventive healthcare provision, but geographic disparities in the receipt of preventive counseling services have not been fully described. In this study the framework of the behavioral model of healthcare utilization was employed to investigate the association between rurality and receiving preventive counseling. It was hypothesized that demographic differences in rural and urban communities, as well as differential healthcare resources, explain rural-urban healthcare disparities in preventive counseling.

METHODS

Data were collected by telephone survey during 2004-2005 for 2002 participants aged 18-45 years in the Central Pennsylvania Women's Health Study. Measures of preventive counseling were based on US Preventive Services Task Force recommendations as of 2004. Multivariable models assessed the independent contribution of rurality to the receipt of counseling for smoking, alcohol/drug use, birth control, nutrition, weight management, and physical activity. Rurality was assessed using Rural-Urban Community Area Codes. All models controlled for variables that predispose individuals to use health services (age, race/ethnicity, educational level), variables that enable or impede healthcare access (having a usual healthcare provider, using an obstetrician-gynecologist, poverty, and continuous health insurance coverage) and need-based variables (health behaviors and indicators).

RESULTS

In bivariate analysis, the rural population was older, had lower educational attainment, and was more likely to be White, non-Hispanic. Urban women tended to report seeing an obstetrician-gynecologist more frequently, and engaged more frequently in binge drinking/drug use. Preventive counseling was low among both rural and urban women, and ranged from 12% of the population for alcohol/drug use counseling, to 37% for diet or nutrition counseling. The degree of rurality appeared to impact counseling, with women in small or isolated rural areas significantly less likely than urban women and women in large rural areas to receive counseling related to smoking, alcohol/drug use and birth control. Overall, rural women reported less counseling for alcohol/drug use, smoking, birth control, nutrition and physical activity. In multivariable analysis, rurality was independently associated with lack of preventive counseling for physical activity. However, adjusting for predisposing, enabling and need-based variables fully attenuated the effect of rurality in the remaining models. Younger age, higher educational attainment, and seeing any obstetrician-gynecologist were associated with receipt of counseling in several models.

CONCLUSIONS

Most women do not receive recommended preventive counseling. While rural women are less likely than urban women to receive counseling, rurality generally was not independently associated with receipt of counseling once demographics, access to health care, and health behaviors and indicators were controlled. This suggests that both demographic differences between rural and urban communities as well as aspects of healthcare access govern rural-urban healthcare disparities in preventive counseling. These results speak to important targets for reducing urban-rural healthcare disparities in receiving preventive counseling, improving the health literacy of the rural population, educating rural healthcare providers about the need for preventive counseling, and the expansion of access to obstetrician-gynecologists in rural communities.

Physician sun protection counseling: prevalence, correlates, and association with sun protection practices among US adolescents and their parents, 2004

OBJECTIVE

To assess the population prevalence and correlates of ever receiving physician advice to practice sun protection (i.e. sun protection counseling) and whether such counseling is associated with sun protection behaviors in adolescents and their parents.

METHOD

Analysis of a nationally representative cross-sectional telephone survey of ultraviolet radiation exposure behaviors among US adolescents ages 11 to 18 and their parents, conducted between August and November 2004.

RESULTS

Forty-four percent of US adolescents and their parents reported physician sun protection counseling. Counseling was more frequently reported by adolescents whose parents were also counseled, reported other sun protection information sources (skin cancer prevention media messages and school sun safety messages), had first degree relatives with skin cancer, and were white, non-Hispanic. Counseling was positively associated with regular sunscreen use, appropriate sunscreen application practices, and intermittent hat use, but not with other recommended behaviors. Sunscreen use rates were generally higher among adolescents reporting several sun protection information sources (counseling, media and school messages) than those with combinations of two or fewer of these sources.

CONCLUSIONS

The role of physicians, either independently or in concert with other information sources, should be explored in strategies promoting primary skin cancer prevention behaviors among adolescents and parents.

Sun-protection behaviors among African Americans

BACKGROUND

Data suggest that the prevalence of sun-protection behaviors is low (44%) among African Americans; the samples in such studies, however, tended to be small or nonrepresentative.

PURPOSE

This article aims to examine the prevalence and correlates of sun-protection behaviors among a large, random, statewide sample of African-American adults living in California to ascertain behavioral patterns and highlight directions for targeted interventions.

METHODS

From September 2006 through May 2008, an anonymous health survey collected data on sunscreen, sunglasses, and wide-brim hat use among a random sample of 2187 African-American adults, and assessed demographic, regional, skin type, and other potential correlates of these behaviors. The analysis was conducted in 2009.

RESULTS

Only 31% engaged in at least one sun-protection behavior; of the three behaviors, sunscreen use was the least prevalent, with 63% never using sunscreen. Multivariate logistic regressions revealed that gender, SES, and skin type were significant predictors of sun-protection behaviors.

CONCLUSIONS

Tailored interventions to increase sun-protection behaviors among African Americans (men in particular) are needed.

Sun protection and skin self-examination in melanoma survivors

OBJECTIVES

Patients diagnosed with melanoma are at risk for developing recurrent and second primary disease. Skin self-examination (SSE) and sun protection are standard clinical recommendations to minimize risk. In this study we examined performance of these behaviors in individuals with melanoma drawn from the general population.

METHODS

Potential participants (N=148) with a first primary melanoma diagnosed in 2000 were identified through a population-based cancer registry in New Jersey, USA. One hundred and fifteen individuals participated in a 30 min telephone interview concerning behavioral adherence with SSE and sun protection, self-efficacy for performing these behaviors, and perceived risk of developing another skin cancer. We utilized logistic regression to estimate potential associations of demographic, medical, and psychosocial factors with SSE and sun protection, respectively.

RESULTS

Seventeen percent of subjects reported performing comprehensive SSE at least once every two months and 23% engaged in regular sun protection. Utilization of SSE was related to the presence of moles (OR=4.2, 95% CI: 1.1-15) and higher SSE self-efficacy (OR=14.4, 95% CI: 1.9-112). Regular sun protection was related to older age (>60 years; OR=3.3, 95% CI: 1.3-8.7), being female (OR=2.8, 95% CI: 1.1-7.3), and higher sun protection self-efficacy (OR=5.0, 95% CI: 1.4-18). These factors remained significant in multivariate models.

CONCLUSION

In this group of primary melanoma survivors, the rates of SSE and sun protection are comparable to, but do not exceed, general population estimates. This study provides justification for further research to address barriers to prevention and control behaviors in melanoma survivors.

Multiple health behavior change research: an introduction and overview

In 2002, the Society of Behavioral Medicine's special interest group on Multiple Health Behavior Change was formed. The group focuses on the interrelationships among health behaviors and interventions designed to promote change in more than one health behavior at a time. Growing evidence suggests the potential for multiple-behavior interventions to have a greater impact on public health than single-behavior interventions. However, there exists surprisingly little understanding of some very basic principles concerning multiple health behavior change (MHBC) research. This paper presents the rationale and need for MHBC research and interventions, briefly reviews the research base, and identifies core conceptual and methodological issues unique to this growing area. The prospects of MHBC for the health of individuals and populations are considerable.

Multiple Health Behavior Research represents the future of preventive medicine

Given the disease and cost burdens, Multiple Health Behavior Research represents the future of preventive medicine. Growing evidence in this special issue and beyond indicates that simultaneous and sequential interventions can be effective. The challenge for the future is to make such interventions more effective, cost effective and less demanding. Co-variation represents one innovative approach in which effective change on one treated behavior increases the odds of effective action on a second targeted behavior. Co-variation can occur when all behaviors received full treatment, when one receives full treatment and the others receive minimal treatment and when only one behavior is treated and others co-vary without treatment. Integrative treatments represent another innovation in which higher order constructs drive change on multiple behaviors related to the construct and treatment has to be only on one higher order behavior. A more integrated approach to research and practice involves new paradigms complementing established paradigms. Multiple behaviors proactively treated in populations at home or work by computer-based and stage-based interventions designed to generate co-variation that produces greater impacts can complement traditional paradigms that treat single behaviors in individual patients in clinics by clinicians with action-oriented modular interventions designed for specific behaviors to produce significant efficacy. More inclusive research to support more inclusive practices can hopefully lead to more inclusive care.
