Health Economics Research in Primary Prevention of Cancer: Assessment, Current Challenges, and Future Directions

In the past 2 decades, the demand for information on health economics research to guide health care decision making has substantially increased. Studies have provided evidence that eliminating or reducing tobacco use; eating a healthy diet, including fruit and vegetables; being physically active; reducing alcohol consumption; avoiding ultraviolet radiation; and minimizing exposure to environmental and occupational carcinogenic agents should substantially reduce cancer incidence in the population. The benefits of these primary prevention measures in reducing cancer incidence are not instantaneous. Therefore, health economics research has an important role to play in providing credible information to decision makers on the health and economic benefits of primary prevention. This article provides an overview of health economics research related to primary prevention of cancer. We addressed the following questions: 1) What are the gaps and unmet needs for performing health economics research focused on primary prevention of cancer? 2) What are the challenges and opportunities to conducting health economics research to evaluate primary prevention of cancer? and 3) What are the future directions for enhancing health economics research on primary prevention of cancer? Modeling primary prevention of cancer is often difficult given data limitations, long delays before the policy or intervention is effective, possible unintended effects of the policy or intervention, and the necessity of outside expertise to understand key inputs or outputs to the modeling. Despite these challenges, health economics research has an important role to play in providing credible information to decision makers on the health and economic benefits of primary prevention of cancer.

Improving rates of ferrous sulfate prescription for suspected iron deficiency anaemia in infants

BACKGROUND

Iron deficiency anaemia (IDA) in infancy is prevalent and associated with impaired neurodevelopment; however, studies suggest that treatment and follow-up rates are poor.

OBJECTIVES

To improve the rate of ferrous sulfate prescription for suspected IDA among infants aged 8-13 months to 75% or greater within 24 months.

METHODS

We implemented a multidisciplinary process improvement effort aimed at standardising treatment for suspected IDA at two academic paediatric primary care clinics. We developed a clinical pathway with screening and treatment recommendations, followed by multiple plan-do-study-act cycles including provider education, targeted reminders when ferrous sulfate was not prescribed and development of standardised procedures for responding to abnormal lab values. We tracked prescription and screening rates using statistical process control charts. In post hoc analyses, we examined rates of haemoglobin (Hgb) recheck and normalisation for the preintervention versus postintervention groups.

RESULTS

The prescription rate for suspected IDA increased from 41% to 78% following implementation of the intervention. Common reasons for treatment failure included prescription of a multivitamin instead of ferrous sulfate, and Hgb not flagged as low by the electronic medical record. Screening rates remained stable at 89%. Forty-one per cent of patients with anaemia in the preintervention group had their Hgb rechecked within 6 months, compared with 56% in the postintervention group (p<0.001). Furthermore, 30% of patients with anaemia in the postintervention group had normalised their Hgb by 6 months, compared with 20% in the preintervention group (p<0.05).

CONCLUSIONS

A multipronged interdisciplinary quality improvement intervention enabled: (1) development of standardised practices for treating suspected IDA among infants aged 8-13 months, (2) improvement of prescription rates and (3) maintenance of high screening rates. Rates of Hgb recheck and normalisation also increased in the intervention period.​.

Recalling and Intending to Enact Health Recommendations: Optimal Number of Prescribed Behaviors in Multibehavior Messages

Two experiments investigated the effects of the number of health recommendations (e.g., quit smoking; relax for a day) contained in a health-promotion message on recommendation recall and intentions to enact the recommendations. We hypothesized that if recommendations are stored individually, a higher number of presented recommendations will increase the number of recalled recommendations. As the number of recommendations increases, however, recipients are likely to summarize more recommendations as part of a single, more general theme (or header), resulting in a decrease in the proportion of recalled recommendations. Two experiments (N = 193 and N = 266) found that the total number of recalled recommendations increased and the proportion of recalled recommendations decreased with the number of presented recommendations. Experiment 2 replicated the findings with the number and the proportion of intended behaviors. The implications of these findings for future behavioral health interventions are discussed.

Innovation in Healthcare: A Systematic Review of Recent Research

Research on innovations in healthcare organizations published between 1994 and 2004 are here reviewed and summarized. The majority of the 31 identified studies dealt with the adoption of innovations and new practices and were cross-sectional designs applying quantitative methods, or multiple case studies applying qualitative methods. Five pathways for future research are recommended: (a) Multilevel approaches studying innovation simultaneously on individual, group, and organizational levels; (b) a combination of quantitative and qualitative data; (c) use of longitudinal designs (innovation both as the dependent and independent variable); (d) application of experimental designs in interventions; and (e) exploration of innovation generation and structural innovations.

Personal health technology: A new era in cardiovascular disease prevention

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality worldwide yet the majority of related risk factors are largely preventable (primary prevention [PP]) and effectively treatable (secondary prevention [SP]) with healthy lifestyle behaviors. The use of information and communication technology (ICT) offers a unique approach to personal health and CVD prevention, as these mediums are relatively affordable, approachable, and accessible. The purpose of this review is to provide an overview of ICT-driven personal health technologies and their potential role in promoting and supporting self-care behaviors for PP and SP of CVD. In this review, we focus on technological interventions that have been successful at supporting positive behavior change in order to determine which tools, resources, and methods are most appropriate for delivering interventions geared towards CVD prevention. We conducted a literature search from a range of sources including scholarly, peer-reviewed journal articles indexed in PubMed and CINAHL, gray literature, and reputable websites and other Internet-based media. A synthesis of existing literature indicates that the overall efficacy of ICT-driven personal health technologies is largely determined by: 1) the educational resources provided and the extent to which the relayed information is customized or individually tailored; and 2) the degree of self-monitoring and levels of personalized feedback or other interactions (e.g. interpersonal communications). We conclude that virtually all the technological tools and resources identified (e.g. Internet-based communications including websites, weblogs and wikis, mobile devices and applications, social media, and wearable monitors) can be strategically leveraged to enhance self-care behaviors for CVD risk reduction and SP but further research is needed to evaluate their efficacy, cost-effectiveness, and long-term maintainability.

The role of disease management programs in the health behavior of chronically ill patients

OBJECTIVE

Investigate the effects of disease management program (DMP) implementation on physical activity, smoking, and physical quality of life among chronically ill patients.

METHODS

This study used a mixed-methods approach involving qualitative (35 interviews with project managers) and quantitative (survey of patients from 18 DMPs) data collection. Questionnaire response rates were 51% (2010; 2619/5108) at T0 and 47% (2011; 2191/4693) at T1.

RESULTS

Physical activity and the percentage of smokers improved significantly over time, whereas physical quality of life declined. After adjusting for patients' physical quality of life at T0, age, educational level, marital status, and gender, physical activity at T0 (p<0.01), changes in physical activity (p<0.001), and percentage of smokers at T0 (p<0.05) predicted physical quality of life at T1. Project managers reported that DMPs improved patient-professional interaction. The ability to set more concrete targets improved patients' health behaviors.

CONCLUSIONS

DMPs appear to improve physical activity among chronically ill patients over time. Furthermore, (changes in) health behavior are important for the physical quality of life of chronically ill patients.

PRACTICE IMPLICATIONS

Redesigning care systems and implementing DMPs based on the chronic care model may improve health behavior among chronically ill patients.

Rural, suburban, and urban differences in factors that impact physician adherence to clinical preventive service guidelines

PURPOSE

Rural-urban disparities in provision of preventive services exist, but there is sparse research on how rural, suburban, or urban differences impact physician adherence to clinical preventive service guidelines. We aimed to identify factors that may cause differences in adherence to preventive service guidelines among rural, suburban, and urban primary care physicians.

METHODS

This qualitative study involved in-depth semistructured interviews with 29 purposively sampled primary care physicians (10 rural, 10 suburban, 9 urban) in Missouri. Physicians were asked to describe barriers and facilitators to clinical preventive service guideline adherence. Using techniques from grounded theory analysis, 2 coders first independently conducted content analysis then reconciled differences in coding to ensure agreement on intended meaning of transcripts.

FINDINGS

Patient epidemiologic differences, distance to health care services, and care coordination were reported as prominent factors that produced differences in preventive service guideline adherence among rural, suburban, and urban physicians. Epidemiologic differences impacted all physicians, but rural physicians highlighted the importance of occupational risk factors in their patients. Greater distance to health care services reduced visit frequency and was a prominent barrier for rural physicians. Care coordination among health care providers was problematic for suburban and urban physicians. Patient resistance to medical care and inadequate access to resources and specialists were identified as barriers by some rural physicians.

CONCLUSIONS

The rural, suburban, or urban context impacts whether a physician will adhere to clinical preventive service guidelines. Efforts to increase guideline adherence should consider the barriers and facilitators unique to rural, suburban, or urban areas.

General health checks in adults for reducing morbidity and mortality from disease

BACKGROUND

General health checks are common elements of health care in some countries. These aim to detect disease and risk factors for disease with the purpose of reducing morbidity and mortality. Most of the commonly used screening tests offered in general health checks have been incompletely studied. Also, screening leads to increased use of diagnostic and therapeutic interventions, which can be harmful as well as beneficial. It is, therefore, important to assess whether general health checks do more good than harm.

OBJECTIVES

We aimed to quantify the benefits and harms of general health checks with an emphasis on patient-relevant outcomes such as morbidity and mortality rather than on surrogate outcomes such as blood pressure and serum cholesterol levels.

SEARCH METHODS

We searched The Cochrane Library, the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Effective Practice and Organisation of Care (EPOC) Trials Register, MEDLINE, EMBASE, Healthstar, CINAHL, ClinicalTrials.gov and WHO International Clinical Trials Registry Platform (ICTRP) to July 2012. Two authors screened titles and abstracts, assessed papers for eligibility and read reference lists. One author used citation tracking (Web of Knowledge) and asked trialists about additional studies.

SELECTION CRITERIA

We included randomised trials comparing health checks with no health checks in adults unselected for disease or risk factors. We did not include geriatric trials. We defined health checks as screening general populations for more than one disease or risk factor in more than one organ system.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed the risk of bias in the trials. We contacted authors for additional outcomes or trial details when necessary. For mortality outcomes we analysed the results with random-effects model meta-analysis, and for other outcomes we did a qualitative synthesis as meta-analysis was not feasible.

MAIN RESULTS

We included 16 trials, 14 of which had available outcome data (182,880 participants). Nine trials provided data on total mortality (155,899 participants, 11,940 deaths), median follow-up time nine years, giving a risk ratio of 0.99 (95% confidence interval (CI) 0.95 to 1.03). Eight trials provided data on cardiovascular mortality (152,435 participants, 4567 deaths), risk ratio 1.03 (95% CI 0.91 to 1.17) and eight trials on cancer mortality (139,290 participants, 3663 deaths), risk ratio 1.01 (95% CI 0.92 to 1.12). Subgroup and sensitivity analyses did not alter these findings.We did not find an effect on clinical events or other measures of morbidity but one trial found an increased occurrence of hypertension and hypercholesterolaemia with screening and one trial found an increased occurence of self-reported chronic disease. One trial found a 20% increase in the total number of new diagnoses per participant over six years compared to the control group. No trials compared the total number of prescriptions, but two out of four trials found an increased number of people using antihypertensive drugs. Two out of four trials found small beneficial effects on self-reported health, but this could be due to reporting bias as the trials were not blinded. We did not find an effect on admission to hospital, disability, worry, additional visits to the physician, or absence from work, but most of these outcomes were poorly studied. We did not find useful results on the number of referrals to specialists, the number of follow-up tests after positive screening results, or the amount of surgery.

AUTHORS' CONCLUSIONS

General health checks did not reduce morbidity or mortality, neither overall nor for cardiovascular or cancer causes, although the number of new diagnoses was increased. Important harmful outcomes, such as the number of follow-up diagnostic procedures or short term psychological effects, were often not studied or reported and many trials had methodological problems. With the large number of participants and deaths included, the long follow-up periods used, and considering that cardiovascular and cancer mortality were not reduced, general health checks are unlikely to be beneficial.

Nutrition initiatives in the context of population aging: where does the United States stand?

In 2011, the earliest segment of the baby boom generation turned 65 years of age. This event marks the beginning of a new phase of growth of the older adult population in the United States and is in line with what is referred to worldwide as "population aging." By 2030, older adults will comprise 20% of the U.S. population. With the impending increase in the older adult population, the United States is unprepared to handle the accompanying social and economic impact of growing rates of age-related diseases such as diabetes, hypertension, and cardiovascular disease. These diseases have nutritional determinants and, as such, they signify the need for effective preventive nutrition initiatives to address population aging in the United States. Comparatively, the European Union (EU) is projected to reach an older adult population of 24% by 2030. In this special article we evaluate nutrition initiatives for older adults in the United States and also examine nutrition initiatives in the European Union in search of an ideal model. However, we found that available data for EU initiatives targeted at population aging were limited. We conclude by offering the proposal of a physician-based model that establishes the primary care physician as the initiator of nutrition screening, education, referrals, and follow-up for the older adult population in the United States as a long-term goal. Apropos of the immediate future, we consider barriers that underscore the establishment of a physician-based model and suggest objectives that are attainable. Although the data are limited for the European Union, this model may serve to guide management of chronic diseases with a nutritional component in economies similar to the United States worldwide.

A web-based patient tool for preventive health: preliminary report

BACKGROUND

The Internet is a promising medium for engaging the community in preventive care and health promotion, particularly among those who do not routinely access health care.

OBJECTIVE

The authors pilot-tested a novel website that translates evidence-based preventive health guidelines into a patient health education tool. The web-based tool allows individuals to enter their health risk factors and receive a tailored checklist of recommended preventive health services based on up-to-date guidelines from the US Preventive Services Task Force and the Advisory Committee on Immunization Practices.

METHODS

The authors conducted surveys and in-depth interviews among a purposive sample of adults from an urban African American community who pilot-tested the website in a standardized setting. Interviews were designed to assess the usability, navigability, and content of the website and capture patient perceptions about its educational value and usefulness. Each interview was audiotaped, transcribed, and examined using the constant comparative method.

RESULTS

Twenty-five participants piloted the tool: 96% found it easy to use and 64% reported learning something new. Many participants reported that, in addition to improving clinical preventive care (the intended purpose), the website could serve as a stand-alone tool to improve self-awareness and motivate behavior change.

CONCLUSIONS

A web-based tool designed to translate preventive health guidelines for the community may serve the dual purpose of improving the delivery of preventive health care and encouraging health promotion. The website developed here is publicly available for use by practitioners and the community.

Prioritization of evidence-based preventive health services during periodic health examinations

BACKGROUND

Delivery of preventive services sometimes falls short of guideline recommendations.

PURPOSE

To evaluate the multilevel factors associated with evidence-based preventive service delivery during periodic health examinations (PHEs).

METHODS

Primary care physicians were recruited from an integrated delivery system in southeast Michigan. Audio recordings of PHE office visits conducted from 2007 to 2009 were used to ascertain physician recommendation for or delivery of 19 guideline-recommended preventive services. Alternating logistic regression was used to evaluate factors associated with service delivery. Data analyses were completed in 2011.

RESULTS

Among 484 PHE visits to 64 general internal medicine and family physicians by insured patients aged 50-80 years, there were 2662 services for which patients were due; 54% were recommended or delivered. Regression analyses indicated that the likelihood of service delivery decreased with patient age and with each concern the patient raised, and it increased with increasing BMI and with each additional minute after the scheduled appointment time the physician first presented. The likelihood was greater with patient-physician gender concordance and less if the physician used the electronic medical record in the exam room or had seen the patient in the past 12 months.

CONCLUSIONS

A combination of patient, patient-physician relationship, and visit contextual factors are associated with preventive service delivery. Additional studies are warranted to understand the complex interplay of factors that support and compromise preventive service delivery.

Patient acceptance and perceived utility of pre-consultation prevention summaries and reminders in general practice: pilot study

BACKGROUND

Patients attending general practices receive only about sixty per cent of the preventive services that are indicated for them. This pilot study explores patient acceptability and perceived utility of automatically generated prevention summary and reminder sheets provided to patients immediately before consultations with their general practitioners.

METHODS

Adult patients attending a general practitioner in a practice in Adelaide and a general practitioner in a practice in Melbourne, Australia for consultations in January and February 2009 received automatically-generated prevention summary and reminder sheets that highlighted indicated preventive activities that were due to be performed, and that encouraged the patient to discuss these with the general practitioner in the consultation. Patients completed a post-consultation questionnaire and were interviewed about their experience of receiving the sheets.

RESULTS

Sixty patients, median age 53 years (interquartile range 40-74) years, and 58% female, were recruited. Seventy eight per cent of patients found the sheets clear and easy to understand, 75% found them very or quite useful, 72% reported they had addressed with their general practitioner all of the preventive activities that were listed on the sheets as being due to be performed. A further 13% indicated that they had addressed most or some of the activities. 78% of patients said that they would like to keep receiving the sheets. Themes emerging from interviews with patients included: patient knowledge was enhanced; patient conceptions of health and the GP consultation were broadened; the consultation was enhanced; patient pro-activity was encouraged; patients were encouraged to plan their health care; the intervention was suitable for a variety of patients.

CONCLUSIONS

Most patients reported that they found the prevention summary and reminder sheets acceptable and useful. The actual increase in performance of preventive activities that may result from this new intervention needs to be tested in randomised controlled trials.

The multiphase optimization strategy for engineering effective tobacco use interventions

The multiphase optimization strategy (MOST) is a new methodological approach for building, optimizing, and evaluating multicomponent interventions. Conceptually rooted in engineering, MOST emphasizes efficiency and careful management of resources to move intervention science forward steadily and incrementally. MOST can be used to guide the evaluation of research evidence, develop an optimal intervention (the best set of intervention components), and enhance the translation of research findings, particularly type II translation. This article uses an ongoing study to illustrate the application of MOST in the evaluation of diverse intervention components derived from the phase-based framework reviewed in the companion article by Baker et al. (Ann Behav Med, in press, 2011). The article also discusses considerations, challenges, and potential benefits associated with using MOST and similar principled approaches to improving intervention efficacy, effectiveness, and cost-effectiveness. The applicability of this methodology may extend beyond smoking cessation to the development of behavioral interventions for other chronic health challenges.

Worsening disparities in HPV vaccine utilization among 19-26 year old women

We evaluated the characteristics associated with uptake of HPV vaccine by 19-26 year old women seen in primary care university-based clinics. Of the 11,545 women analyzed only 18% had initiated the 3-dose vaccine series. Series completion among the sample overall was only 10% in the 30 month study period. Decreased series initiation was associated with older age, public insurance, white race and non-family medicine specialty. Decreased series completion was associated with public insurance and African American race. Utilization disparities by race and insurance worsened over time suggesting that the highest risk populations of women were not getting vaccinated.

Health care utilization by adolescents on medicaid: implications for delivering vaccines

OBJECTIVE

To examine the degree to which current health care utilization patterns of Medicaid-enrolled adolescents living in Michigan would allow opportunities for adolescent immunizations to be provided.

METHODS

Outpatient claims data from 2001-2005 were analyzed for 11- to 18-year-old Medicaid-enrolled adolescents living in Michigan. Visits were classified as either health-maintenance examinations (HMEs) or problem focused by using diagnostic and procedural codes. Data were divided into 4 overlapping 2-year time periods, and the age-specific proportion of adolescents who attended these 2 visit types was calculated for each. chi(2) tests were used to evaluate associations of visit patterns with gender.

RESULTS

Of the 718847 adolescents included in the study, <50% had >or=1 HME visit within any 2-year time period, and substantially fewer (<15%) had annual HMEs. In contrast, at least 75% of the adolescents had >or=1 problem-focused visit in any given 2-year period, and approximately half had participated in at least 2 problem-focused visits. Problem-focused, but not HME, visit utilization was significantly associated with gender, with girls increasing, but boys decreasing, visit utilization as they aged.

CONCLUSIONS

Similar to privately insured adolescents, most Medicaid-enrolled adolescents do not have annual preventive-care visits, which calls into question the feasibility of providing immunizations primarily at annual HMEs. Participation in problem-focused encounters was generally high in our study. However, even problem-focused visit utilization was low among older adolescent boys. This suggests that in addition to strengthening immunization within the medical home, alternative venues for reaching certain subpopulations of adolescents should also be developed.

Patient and clinic factors associated with adolescent human papillomavirus vaccine utilization within a university-based health system

We reviewed clinical and billing data from a university-based health system to assess HPV vaccine utilization among 9-18-year-old girls by individual, visit and medical specialty characteristics. Our sample included 10,082 adolescent patients with 27,928 visits to outpatient family medicine (FM), pediatric and gynecology clinics between January 2007 and March 2008. Vaccine series completion was low among eligible adolescents (15%), with important disparities in vaccine utilization by medical specialty, age, race and insurance status. Missed opportunities for vaccination were common. Our findings may help to target future interventions aimed at increasing adolescent HPV vaccine utilization.

Initiation of health behavior discussions during primary care outpatient visits

OBJECTIVE

Despite the importance of health promotion, rates of health behavior advice remain low and little is known about how advice is integrated into routine primary care. This study examines how health behavior topics of diet, physical activity and smoking are initiated during outpatient visits.

METHODS

Audio recording of 187 adults visit to five purposefully selected physicians. An iterative analysis involved listening to and discussing cases to identify emergent patterns of initiation of health behavior talk and advice that followed.

RESULTS

Physicians initiated 65% of discussions and used two overarching strategies (1) Structured: a routine to ask about health behavior and (2) Opportunistic: use of a trigger to make a transition to talk about health behavior. Opportunistic strategies identified a greater proportion of patients at risk (50% vs. 34%) and led to a greater rate of advice (100% vs. 75%). Patients initiated one-third of health behavior discussions and were more likely to receive advice if they explicitly indicated readiness to change.

CONCLUSIONS

Opportunistic strategies show promise for a higher yield of identifying patients at risk and leading to advice.

PRACTICE IMPLICATIONS

Encouraging patients to be explicit about their readiness to change is likely to increase physician advice and assistance.

Human papillomavirus vaccine and adolescents

PURPOSE OF REVIEW

The present review describes recent advances in our understanding about the epidemiology of human papillomavirus infection among female adolescents and describes several adolescent-specific issues related to administering human papillomavirus vaccines.

RECENT FINDINGS

National estimates demonstrate that human papillomavirus infection is most prevalent among adolescents and young adults. Parents, patients, and providers have a high interest in vaccination against this virus, but current patterns of adolescent healthcare utilization suggest that changes in adolescent preventive care delivery may be needed to provide these vaccines in a timely manner. Debate over whether adolescents should be legally allowed to self-consent to vaccination is another issue that remains unresolved and could have a substantial impact on vaccination rates. Legislation on school entry requirements related to human papillomavirus vaccination has been introduced in many states as a mechanism to circumvent some of these concerns, but the details of this legislation and its effect on adolescent vaccine utilization remain to be determined.

SUMMARY

Female adolescents are at a high risk for human papillomavirus infection and are likely to derive significant benefits from vaccination against this virus. However, administering human papillomavirus vaccines to this age group will require providers to be familiar with several issues unique to the adolescent population.

Adolescent immunizations and other clinical preventive services: a needle and a hook?

Advances in technology have led to development of new vaccines for adolescents, but these vaccines will be added to a crowded schedule of recommended adolescent clinical preventive services. We reviewed adolescent clinical preventive health care guidelines and patterns of adolescent clinical preventive service delivery and assessed how new adolescent vaccines might affect health care visits and the delivery of other clinical preventive services. Our analysis suggests that new adolescent immunization recommendations are likely to improve adolescent health, both as a "needle" and a "hook." As a needle, the immunization will enhance an adolescent's health by preventing vaccine-preventable diseases during adolescence and adulthood. It also will likely be a hook to bring adolescents (and their parents) into the clinic for adolescent health care visits, during which other clinical preventive services can be provided. We also speculate that new adolescent immunization recommendations might increase the proportion and quality of other clinical preventive services delivered during health care visits. The factor most likely to diminish the positive influence of immunizations on delivery of other clinical preventive services is the additional visit time required for vaccine counseling and administration. Immunizations may "crowd out" delivery of other clinical preventive services during visits or reduce the quality of the clinical preventive service delivery. Complementary strategies to mitigate these effects might include prioritizing clinical preventive services with a strong evidence base for effectiveness, spreading clinical preventive services out over several visits, and withholding selected clinical preventive services during a visit if the prevention activity is effectively covered at the community level. Studies are needed to evaluate the effect of new immunizations on adolescent preventive health care visits, delivery of clinical preventive services, and health outcomes.

Do adults who believe in periodic health examinations receive more clinical preventive services?

BACKGROUND

Individuals who have periodic health examinations ("check-ups") with physicians even if they feel well have higher rates of screening and other preventive services than individuals who only see physicians when ill. This study assessed whether individuals' beliefs about the advisability of periodic health examinations contribute to the likelihood that they receive recommended clinical preventive services.

METHODS

This study used data from a 2002-2003 telephone survey of adults in 150 rural counties in 8 states of the U.S. southeast. Weighted Chi-square and logistic regression analyses were used to assess associations between attitudes towards periodic health examinations and the receipt of preventative services.

RESULTS

Of the 4879 respondents, 37% were African American, and 43% had annual household incomes of less than $25,000. A total of 8.5% (n=374) did not endorse periodic health examinations. Not endorsing periodic examinations was more common among subjects who were male, younger, white and had no health insurance. Compared to those who endorsed periodic examinations, persons who did not were less likely to have had a periodic examination (42% versus 80%, p<0.001) or mammogram (28% versus 60%, p<0.001) in the previous year, a Pap smear in past 3 years (74% versus 90%, p<0.001), a cholesterol check in the last 5 years (56% versus 81%, p<0.001) or to ever have had endoscopic screening (28% versus 48%, p<0.001). These rate differences remained after adjusting for sociodemographic characteristics.

CONCLUSION

People's beliefs about the value of periodic health examinations are associated with the likelihood that they receive recommended preventative services. Understanding individuals' beliefs about health, disease prevention and the role of physicians in prevention could lead to improved targeted interventions aimed at increasing uptake of preventative services.

Preventive service delivery: A new insight into French general practice

OBJECTIVE

The importance of prevention is increasingly recognised in most developed countries. General practitioners (GPs) have got a key role to play in this domain in primary care. But, the research evidence still concludes that GPs' preventive activities remain most of the time insufficient. The aim of our study was to contribute to this debate in adopting a more broad view of prevention-related activities to better understand the GPs practice in this matter. Our study was undertaken to measure the part of prevention-related activity hidden in each of the morbid conditions (MC) seen by the doctors daily.

METHODS

We carried out a cross-sectional study in a sample of 75 French GPs in the south suburb of Paris. We dropped the usual pre-established and limited list of specific preventive care activities to replace it with a list of 100 most common morbid conditions seen by the GPs in daily practice. The GPs were asked for each selected MC to rate on a five-item Likert scale the amount of primary and secondary prevention they generally offer during a patient visit.

RESULTS

All MC confounded, secondary prevention reached an average score of 3.2 (inter-quartile interval 2.82-3.58). The intensity of primary prevention was somewhat lower, but far from being negligible. Its average score was 2.3 (inter-quartile interval of 1.86-2.73). If more than 50% of the GPs declare a low intensity of primary prevention activity or even no primary prevention activity at all in nearly 3/4 of the MC encountered in their daily practice, they also declare that they carry out a considerable amount of primary prevention or in some cases spend the entire patient visit to primary prevention for MC covering more than 25% of their daily activity. Also, even if a majority of GPs did not give clear-cut scores for secondary prevention for 2/3 of the MC, they declare a considerable amount of it for the remaining 1/3 which covers more than 25% of their activity.

CONCLUSION

Our study was useful to offer a more realistic view of the real place of the prevention-related activities in the GPs daily primary care practice even if we assess neither the appropriateness nor the quality of these activities.

Practical Behavior Change Counseling in Primary Care

Unhealthy behaviors lead to significant preventable morbidity and mortality in the United States. Primary care providers are in a unique position to address these issues with patients. Despite the importance and opportunity for health behavior counseling in primary care, reported rates are low. This article presents a practical model for health behavior counseling in everyday clinical practice.

Determinants of preventive services in general practice

BACKGROUND

France is in Europe, the country in which the mortality due to potentially preventable causes is the highest. At the same time, French doctors receive no incentives to undertake prevention activities. This article examined the general practitioners' (GPs) determinants (characteristics, patient list and contextual factors) of cardiovascular prevention and vaccination carried out by GPs in their offices.

METHODS

Data were collected from 105,726 patients followed by 86 GPs (observational study). A multilevel analysis with two levels: GP and patient (HLM) was performed.

RESULTS

A high between-GP variability of the prevention activity is underlined in both domains. After controlling for patient characteristics, we observed a positive effect of the GP's workload (ORa=1.03) and of an elderly GP's patient list (ORa=1.04) on cardiovascular prevention, a positive effect of a patient list with a high level of health care consumption on vaccination activity (ORa=1.04). The significant influence of contextual factors is ever more demonstrative: the ORa is 1.3 times lower in cardiovascular prevention and 1.6 in vaccination when the density of GPs in the local community of the doctor's practice grows of one-point (1/1000); the ORa is two times lower in both cardiovascular prevention and vaccination for GPs having an urban practice.

CONCLUSION

These results emphasize the need for taking into account contextual factors to implement prevention policies in primary care. But further studies of this type should be conducted by taking other variables into account in order to improve the proportion of variance explained in our models.

Rethinking prevention in primary care: applying the chronic care model to address health risk behaviors

This study examines the Chronic Care Model (CCM) as a framework for preventing health risk behaviors such as tobacco use, risky drinking, unhealthy dietary patterns, and physical inactivity. Data were obtained from primary care practices participating in a national health promotion initiative sponsored by the Robert Wood Johnson Foundation. Practices owned by a hospital health system and exhibiting a culture of quality improvement were more likely to offer recommended services such as health risk assessment, behavioral counseling, and referral to community-based programs. Practices that had a multispecialty physician staff and staff dieticians, decision support in the form of point-of-care reminders and clinical staff meetings, and clinical information systems such as electronic medical records were also more likely to offer recommended services. Adaptation of the CCM for preventive purposes may offer a useful framework for addressing important health risk behaviors.

Physician practice patterns and variation in the delivery of preventive services

BACKGROUND

Strategies to improve preventive services delivery (PSD) have yielded modest effects. A multidimensional approach that examines distinctive configurations of physician attributes, practice processes, and contextual factors may be informative in understanding delivery of this important form of care.

OBJECTIVE

We identified naturally occurring configurations of physician practice characteristics (PPCs) and assessed their association with PSD, including variation within configurations.

DESIGN

Cross-sectional study.

PARTICIPANTS

One hundred thirty-eight family physicians in 84 community practices and 4,046 outpatient visits.

MEASUREMENTS

Physician knowledge, attitudes, use of tools and staff, and practice patterns were assessed by ethnographic and survey methods. PSD was assessed using direct observation of the visit and medical record review. Cluster analysis identified unique configurations of PPCs. A priori hypotheses of the configurations likely to perform the best on PSD were tested using a multilevel random effects model.

RESULTS

Six distinct PPC configurations were identified. Although PSD significantly differed across configurations, mean differences between configurations with the lowest and highest PSD were small (i.e., 3.4, 7.7, and 10.8 points for health behavior counseling, screening, and immunizations, respectively, on a 100-point scale). Hypotheses were not confirmed. Considerable variation of PSD rates within configurations was observed.

CONCLUSIONS

Similar rates of PSD can be attained through diverse physician practice configurations. Significant within-configuration variation may reflect dynamic interactions between PPCs as well as between these characteristics and the contexts in which physicians function. Striving for a single ideal configuration may be less valuable for improving PSD than understanding and leveraging existing characteristics within primary care practices.

English proficiency and physicians' recommendation of Pap smears among Hispanics

BACKGROUND

Hispanics have one of the highest incidence rates of cervical cancer. Physician recommendation is one of the most important cues to cancer screening; however, low English proficiency among Hispanics may hinder health providers' recommendation of Pap smears.

METHODS

Analysis of data from the 2000 National Health Interview Survey. All Hispanic women, age > or =18, without a Pap smear in the past 3 years or ever and who visited a health care provider in the past year were included. The main outcome was receipt of Pap smear recommendation by a health care provider.

RESULTS

A total of 314 Hispanic women were included in the analysis, 44.9% were highly English proficient. Only 7.7% of low English proficient Hispanics not up-to-date in cancer screening reported a recommendation for a Pap smear as compared to 14.3% of highly proficient Hispanics. After adjusting for sociodemographics and health access and utilization factors, highly English proficient Hispanics were more than two times as likely to report receiving a recommendation for a Pap smear as compared to the less proficient (aOR 2.2, 95% CI 1.1-4.5).

CONCLUSIONS

Low English language proficiency is a barrier to receive a recommendation for Pap smear among Hispanic women not up-to-date with cervical cancer screening. Further research is needed to explore specific mechanisms responsible for the low recommendation rates and to assess the impact of interpreters or Spanish-speaking providers on Pap smear recommendation rates.

Implementing a computer-assisted telephone interview (CATI) system to increase colorectal cancer screening: a process evaluation

OBJECTIVE

Computer-assisted telephone interviewing (CATI) systems used by telephone counselors (TCs) may be efficient mechanisms to counsel patients on cancer and recommended preventive screening tests in order to extend a primary care provider's reach to his/her patients. The implementation process of such a system for promoting colorectal (CRC) cancer screening using a computer-assisted telephone interview (CATI) system is reported in this paper.

METHODS

The process evaluation assessed three components of the intervention: message production, program implementation and audience reception.

RESULTS

Of 1181 potentially eligible patients, 1025 (87%) patients were reached by the TCs and 725 of those patients (71%) were eligible to receive counseling. Five hundred eighty-two (80%) patients agreed to counseling.

CONCLUSIONS

It is feasible to design and use CATI systems for prevention counseling of patients in primary care practices.

PRACTICE IMPLICATIONS

CATI systems have the potential of being used as a referral service by primary care providers and health care organizations for patient education.

Influence of primary care practice and provider attributes on preventive service delivery

BACKGROUND

While visits to the doctor's office are appropriate times to advise patients on health behaviors, these opportunities are often missed. Lapses in care quality are no longer attributed solely to individuals, but are also increasingly understood to be the result of organizational factors. This research examines the influence that both practice and provider attributes have on the delivery of preventive services for health behaviors.

METHODS

This study used data collected from the Prescription for Health initiative sponsored by the Robert Wood Johnson Foundation. Quantitative data on 52 primary care practices and 318 healthcare providers were gathered from September 2003 to September 2004, and were analyzed upon completion of data collection. Hierarchical linear modeling was used to examine associations between both practice and provider attributes and preventive service delivery.

RESULTS

Practice staff participation in decisions regarding quality improvement, practice change, and clinical operations positively influenced the effect of work relationships and negatively influenced the effect of practice size on service delivery. Nurse practitioners and allied health professionals reported more frequent delivery of services compared to physicians. Last, use of reminder systems and patient registries were positively associated with preventive service delivery.

CONCLUSIONS

This study offers preliminary support for staff participation in practice decisions as a positive aspect of teamwork and collaboration. Findings also suggest leveraging nonphysician clinical staff and organized clinical systems to improve the delivery of preventive services for health behaviors.

Office Systems for Heart Disease Prevention

The provision of heart disease prevention services in primary care is currently inadequate, but can be improved with the establishment of a practice system. The system process involves all members of the practice in a clearly defined, well-organized approach to patient care. An initial review of patient care services will help practices identify prevention areas that they would like to improve by defining protocols, roles, and routines within the practice. Once established, the prevention system can improve patient care and satisfaction of practice staff and physicians, but requires on-going assessment, modification, and commitment.

Delivery of clinical preventive services in family medicine offices

BACKGROUND

This study aimed to elucidate how clinical preventive services are delivered in family practices and how this information might inform improvement efforts.

METHODS

We used a comparative case study design to observe clinical preventive service delivery in 18 purposefully selected Midwestern family medicine offices from 1997 to 1999. Medical records, observation of outpatient encounters, and patient exit cards were used to calculate practice-level rates of delivery of clinical preventive services. Field notes from direct observation of clinical encounters and prolonged observation of the practice and transcripts from in-depth interviews of practice staff and physicians were systematically examined to identify approaches to delivering clinical preventive services recommended by the US Preventive Services Task Force.

RESULTS

Practices developed individualized approaches for delivering clinical preventive services, with no one approach being successful across practices. Clinicians acknowledged a 3-fold mission of providing acute care, managing chronic problems, and prevention, but only some made prevention a priority. The clinical encounter was a central focus for preventive service delivery in all practices. Preventive services delivery rates often appeared to be influenced by competing demands within the clinical encounter (including between different preventive services), having a physician champion who prioritized prevention, and economic concerns.

CONCLUSIONS

Practice quality improvement efforts that assume there is an optimal approach for delivering clinical preventive services fail to account for practices' propensity to optimize care processes to meet local contexts. Interventions to enhance clinical preventive service delivery should be tailored to meet the local needs of practices and their patient populations.

Physicians' attitudes and preventive care delivery: insights from the DOPC study

BACKGROUND

Interventions that modify physician attitudes to enhance preventive service delivery are common, yet other factors may be relatively more important in determining whether these services are provided. We assessed associations between physicians' attitudes and delivery of preventive care, compared with factors related to the patient, visit, or practice.

METHODS

One hundred twenty-eight primary care physicians rated the importance of five preventive services and their effectiveness at delivering them. We assessed whether their patients had received cervical smears, prostate-specific antigen (PSA) testing, smoking cessation advice, recommendation to use aspirin to prevent myocardial infarction, or weight-maintenance counseling, when appropriate. Multilevel models assessed associations between physician attitudinal characteristics and a patient's likelihood of being up to date for each service.

RESULTS

Importance of PSA screening and tobacco cessation counseling were weakly associated with patients' receipt of preventive care; no association between attitudes and other services was observed. Factors such as having a visit for well care and use of prevention flowcharts were associated with delivery of preventive services to a greater extent.

CONCLUSIONS

Physicians' attitudes toward prevention are necessary, but not sufficient in ensuring the delivery of preventive services. Future interventions should address visit- and practice-specific factors more closely associated with preventive care.

U.S. adolescents receive suboptimal preventive counseling during ambulatory care

PURPOSE

To examine U.S. adolescents' (age 13-18) utilization of ambulatory care and the likelihood of receiving preventive counseling from 1993 through 2000.

METHODS

The National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey provided visit-based data on counseling services that occurred in private physician offices and hospital outpatient departments. Main outcome measures included adolescents' use of outpatient care and their likelihood of being counseled on 3 health promotion topics (i.e., diet, exercise, and growth/development) and 5 risk reduction topics (i.e., tobacco use/exposure, skin cancer prevention, injury prevention, family planning/contraception, and HIV/STD transmission).

RESULTS

Adolescents had the lowest rates of outpatient visits among all age groups, with particularly low rates among boys and ethnic minorities. Most frequently, adolescent visits were for upper respiratory tract conditions, acne, routine medical or physical examinations, and, for girls, prenatal care. In 1997-2000, counseling services were documented for 39% (99% CI: 32-46%) of all adolescent general medical/physical examination (GME) visits. Diet [26% of GME visits (20-32%)] and exercise [22% (17-28%)] were the most frequent counseling topics. The counseling rates of the other six topics ranged from as low as 3 to 20%, with skin cancer prevention, HIV/STD transmission, and family planning/contraception ranking the lowest. These rates represented minimal improvements from 1993-1996 both in absolute term and in relation to the gaps between practices and recommendations.

CONCLUSIONS

Adolescents underutilize primary care, and even those who do receive care are underserved for their health counseling needs. The noted lack of change over time suggests that satisfactory improvement is unlikely unless substantial interventions are undertaken.

Clinical effect of computer generated physician reminders in health screening in primary health care--a controlled clinical trial of preventive services among the elderly

OBJECTIVES

To apply and evaluate the effects of a program for computer generated physician reminders, integrated with an electronic patient record (EPR) system, for opportunistic health screening in elderly patients.

DESIGN

A pilot study designed as a 20-month clinical trial with a control group and a 20-month non-intervention follow-up using a computer reminder program that selects patients for screening in five intervention areas (diabetes, hypertension, cobalamin deficiency, hypothyroidism and anaemia).

SETTING

Four primary health care (PHC) centres in suburban Stockholm.

SUBJECTS

The intervention was designed for patients 70 years or older from one health care centre who visited a general practitioner (GP) during the first 20-month period. Patients from the three remaining centres served as controls.

MAIN OUTCOME MEASURES

The number of patients who underwent the tests, who had pathological test results, new diagnoses and new pharmacological treatments in both patient groups.

RESULTS

In total, 602 patients underwent screening and 1989 were controls. There was a statistically significant, moderate or marked increase (13-75%) in the number of patients who were tested in all five intervention areas. An increase in pathological test results (1-8%) was found in two areas: hypertension and cobalamin deficiency. There was an increase in the number of patients with the diagnosis of cobalamin deficiency during the study. At follow-up a decrease in new diagnoses for anaemia was found.

CONCLUSION

The system seems to be associated with a moderate to large increase in laboratory and manual screening tests for both established and new screening areas. The effect on clinical outcomes was found mainly in a not-yet-established screening area (cobalamin deficiency), indicating that the system may be clinically useful when introducing new screening services.

Cancer Prevention Services and Physician Consensus in Primary Care Group Practices

Background: We conducted a randomized clinical trial of interventions to achieve physician consensus, practice changes, and patient activation designed to help primary care group practices enhance the delivery of cancer prevention and screening services. Methods: In each of 42 primary care practices in 1991 to 1994, we studied approximately 60 patients per physician who were between the ages 53 and 64. Data sources included patient and physician questionnaires, medical record audits of consenting patients for evidence of 11 cancer prevention services during the previous 3 years, and telephone interviews with key practice personnel. Results: None of the interventions was associated with significant changes in frequency of services or procedures received or provided. Increased frequencies of services overall and of specific activities were associated with HMO membership or insurance coverage for six screening procedures. Patient reports of clinic staff recommendations to have each of six screening procedures were specifically associated with higher frequencies of services (P = 0.001). Conclusions: Demonstration of intervention impact may have been limited because the rates of prevention services were significantly higher in this study than have been reported elsewhere. These results might be explained by selection biases inherent in studying patients with a regular provider, overall practice trends for changes in provision of the studied services, and the study methods.

Primary care physician attitudes concerning follow-up of abnormal test results and ambulatory decision support systems

OBJECTIVES

Failures to follow-up abnormal test results are common in ambulatory care. Information systems could assist providers with abnormal test result tracking, yet little is known about primary care providers attitudes toward outpatient decision support systems.

METHODS

A cross-sectional survey of 216 primary care physicians (PCPs) that utilize a single electronic medical record (EMR) without computer-based clinical decision support.

RESULTS

The overall response rate was 65% (140/216). Less than one-third of the respondents were satisfied with their current system to manage abnormal laboratory, radiographs, Pap smear, or mammograms results. Only 15% of providers were satisfied with their system to notify patients of abnormal results. Over 90% of respondents felt automated systems to track abnormal test results would be useful. Seventy-nine percent of our respondents believed that they could comply better with guidelines through electronic clinical reminders.

CONCLUSIONS

Most PCPs were not satisfied with their methods for tracking abnormal results. Respondents believed that clinical decision support systems (CDSS) would be useful and could improve their ability to track abnormal results.

Direct observation and patient recall of health behavior advice

BACKGROUND

Patient recall of health behavior change discussions with physicians is an important intermediate outcome to adherence with recommendations and subsequent behavior change. This study reports patient recall of health behavior discussions during outpatient visits and tests patient and visit characteristics associated with recall.

METHODS

In a cross-sectional study of 2670 adult outpatients visiting 138 family physicians in 84 practices, provision of health behavior advice was measured by direct observation. Patient recall of discussion of each health behavior topic was assessed by patient survey.

RESULTS

Patient recall rates ranged from 11% for substance use assessment to 75% of smokers recalling smoking cessation advice. Patient demographics were not associated with recall. In multivariable models, the strongest predictor of patient recall of diet and exercise advice was the duration of the advice. Advice provided during well care visits was more likely to be recalled by patients than during illness visits, but presence of a health behavior-relevant diagnosis during an illness visit was associated with a 2-fold increase in patient recall.

CONCLUSIONS

Patient recall of health behavior advice is enhanced by longer duration of advice and by linking advice to visit contexts that represent teachable moments.

Approaches to Breast Cancer Screening Among Nurse Practitioners

PURPOSE

To determine nurse practitioners' (NPs') knowledge and reported practices regarding breast cancer screening in a climate of conflicting guidelines.

DATA SOURCE

A descriptive, cross-sectional survey design was used to examine approaches to cancer screening among NPs in western New York.

CONCLUSIONS

Among the 175 NP respondents, agreement with the accepted answers for the individual breast cancer-screening items ranged from 51% to 80%; responses did not vary by age group or gender. Overall, 54% demonstrated agreement with three or more of four breast cancer-screening items.

IMPLICATIONS FOR PRACTICE

These findings suggest the need to implement educational interventions as one means of decreasing variation in breast cancer screening among NPs. Also, the development and endorsement of a single set of evidence-based breast cancer-screening guidelines would promote adoption of a single screening recommendation.

Developing and testing new smoking measures for the Health Plan Employer Data and Information Set

OBJECTIVE

To develop and test items for the Health Plan Employee Data and Information Set (HEDIS) that assess delivery of the full range of provider-delivered tobacco interventions.

MATERIALS AND METHODS

The authors identified potential items via literature review; items were reviewed by national experts. Face validity of candidate items was tested in focus groups. The final survey was sent to a random sample of 1711 adult primary care patients; the re-test survey was sent to self-identified smokers.

RESULTS

The process identified reliable items to capture provider assessment of motivation and provision of assistance and follow-up.

CONCLUSIONS

One can reliably assess patient self-report of provider delivery of the full range of brief tobacco interventions. Such assessment and feedback to health plans and providers may increase use of evidence-based brief interventions.

Tools, teamwork, and tenacity: an examination of family practice office system influences on preventive service delivery

BACKGROUND

Most research examining primary care office characteristics and preventive service delivery (PSD) has evaluated preventive service aids and equipment, while generally overlooking the complex interactions among multiple office systems where multiple factors influence the overall practice. We test a theoretical model of practice influences on PSD that accounts for Tools (preventive service aids/equipment), Teamwork (office organization), and Tenacity (prevention delivery attitudes).

METHODS

Office characteristics and 4454 patient visits were observed for 138 family physicians in northeast Ohio. Utilizing U.S. Preventive Services Task Force recommendations, age- and gender-specific PSD summary scores were computed for each patient and then averaged per physician. Multivariate analysis of variance tested office characteristic associations with PSD scores.

RESULTS

Tools were common, but most were not significantly associated with PSD scores. The Teamwork indicators of clear staff role expectations and shared vision among physician and staff existed, respectively, for 80 and 73% of physicians. A high average reported practice focus on prevention existed, despite low staff involvement in PSD (22.2%). Compared with Tools, more Teamwork and Tenacity characteristics were associated with the PSD scores.

CONCLUSION

Teamwork and Tenacity appear to be more important than Tools in delivering preventive services in primary care practices.

Does health habit counseling affect patient satisfaction?

BACKGROUND

Health behavior advice can potentially prevent a large burden of illness, but the acceptability of this advice to patients is not well understood. This study assessed whether physician discussion of behavioral risk factors decreases patient satisfaction with the outpatient visit.

METHODS

In a cross-sectional study of 2,459 consecutive adult outpatient visits to 138 community family physicians in Northeast Ohio, the association of health habit counseling, measured by direct observation, with patient satisfaction, assessed by a modified subscale of the MOS 9-item visit rating scale, was calculated by logistic regression.

RESULTS

In analyses controlling for patient mix, discussion of diet, exercise, alcohol and other substance use, sexually transmitted disease, and HIV prevention was not associated with patient satisfaction. Patients who were asked about their tobacco use or counseled about quitting were more likely to be very satisfied with the physician.

CONCLUSIONS

Discussion of health behavior change, as practiced by community family physicians, is not associated with diminished patient satisfaction. In fact, tobacco use assessment and cessation counseling are associated with greater satisfaction.

The delivery of preventive services for patient symptoms

BACKGROUND

Although data are available on rates of delivery of preventive services by primary care physicians, the proportion of services delivered because of related symptoms or signs, rather than for primary or secondary prevention of disease is not known.

METHODS

Research nurses directly observed 4454 consecutive visits to 138 practicing family physicians. Direct observation was used to identify delivery of 36 different services recommended by the U.S. Preventive Services Task Force and to assess whether delivery of these services was associated with related signs or symptoms.

RESULTS

One or more preventive services were delivered in 33% of visits, with rates ranging from 0.2% (HIV prevention) to 19.9% (tobacco counseling). In contrast to pure prevention, services were frequently performed for assessment or care of symptoms or signs, with the ratio ranging from 0% (eye examination; car seat, poison control, and HIV prevention counseling) to 66.7% (hearing test). Physicians varied considerably in the frequency at which their delivery of recommended preventive services was associated with patient symptoms, from 0% to 100% for screening services and from 0% to 100% for counseling services.

CONCLUSIONS

Because of the illness focus of most primary care visits, preventive service delivery is often associated with related signs or symptoms. Care of illnesses appears to present an important impetus and perhaps teachable moments for providing preventive care. Clinician variability in preventive service delivery for patient symptoms shows an opportunity to improve the primary and secondary prevention focus of practice to meet public health prevention goals.

Priorities among recommended clinical preventive services

BACKGROUND

Many recommended clinical preventive services are delivered at low rates. Decision-makers who wish to improve delivery rates, but face competing demands for finite resources, need information on the relative value of these services. This article describes the results of a systematic assessment of the value of clinical preventive services recommended for average-risk patients by the U.S. Preventive Services Task Force.

METHODS

The assessment of services' value for the U.S. population was based on two dimensions: burden of disease prevented by each service and cost effectiveness. Methods were developed for measuring these criteria consistently across different types of services. A companion article describes the methods in greater detail. Each service received 1 to 5 points on each of the two dimensions, for total scores ranging from 2 to 10. Priority opportunities for improving delivery rates were determined by comparing the ranking of services with what is known of current delivery rates nationally.

RESULTS

The highest ranked services (scores of 7+) with the lowest delivery rates (< or =50% nationally) are providing tobacco cessation counseling to adults, screening older adults for undetected vision impairments, offering adolescents an anti-tobacco message or advice to quit, counseling adolescents on alcohol and drug abstinence, screening adults for colorectal cancer, screening young women for chlamydial infection, screening adults for problem drinking, and vaccinating older adults against pneumococcal disease.

CONCLUSIONS

Decision-makers can use the results to set their own priorities for increasing delivery of clinical preventive services. The methods provide a basis for future priority-setting efforts.

A clinical trial of tailored office systems for preventive service delivery. The Study to Enhance Prevention by Understanding Practice (STEP-UP)

BACKGROUND

The potential of primary care practice settings to prevent disease and morbidity through health habit counseling, screening for asymptomatic disease, and immunizations has been incompletely met. This study was designed to test a practice-tailored approach to increasing preventive service delivery with particular emphasis on health habit counseling.

DESIGN

Group randomized clinical trial and multimethod process assessment.

SETTING/PARTICIPANTS

Seventy-seven community family practices in northeast Ohio.

INTERVENTION

After a 1-day practice assessment, a nurse facilitator met with practice clinicians and staff and assisted them with choosing and implementing individualized tools and approaches aimed at increasing preventive service delivery.

MAIN OUTCOME MEASURE

Summary scores of the health habit counseling, screening and immunization services recommended by the U.S. Preventive Services Task Force up to date for consecutive patients during randomly selected chart review days.

RESULTS

A significant increase (p=0.015) in global preventive service delivery rates at the 1-year follow-up was found in the intervention group (31% to 42%) compared to the control group (35% to 37%). Rates specifically for health habit counseling (p=0.007) and screening services (p=0.048) were increased, but not for immunizations.

CONCLUSIONS

An approach to increasing preventive service delivery that is individualized to meet particular practice needs can increase global preventive service delivery rates.

Factors associated with self-reported pneumococcal immunization among adults 65 years of age or older in the Minneapolis-St. Paul metropolitan area

BACKGROUND

As part of a 3-year demonstration project to improve pneumococcal polysaccharide vaccine (PPV) coverage among older adults, the Minnesota Department of Health conducted a baseline evaluation of knowledge, attitudes, and beliefs among the general public regarding PPV.

METHODS

A random-digit dialing telephone survey was conducted among community-dwelling adults age 65 years or older in three metropolitan counties in Minnesota during April through June 1998.

RESULTS

Three hundred fifty-three interviews were completed; self-reported PPV coverage was 59% (95% CI 54%, 64%). Nearly all (94%) respondents reported at least one medical visit in the past year. Unvaccinated respondents expressed willingness to be vaccinated if they knew about PPV's safety, dosage, and preventive role. In a final multivariate regression model, factors associated with PPV vaccination included awareness of PPV (OR 7.8; CI 2.1, 29.2; P = 0.002), opinion that receiving PPV is "very important" (OR 8.3; CI 3.2, 21.6; P < 0.001), awareness that Medicare covers PPV (OR 5.1; CI 1.9, 13.8; P = 0.001), physician ever offering PPV (OR 21.7; CI 6.2, 76.6; P < 0.001), and physician regularly offering PPV (OR 3.9; CI 1.1, 13.7; P = 0.03).

CONCLUSIONS

Respondents were significantly influenced by their physician offering PPV. Therefore, providers' practices are a critical target for improving PPV coverage. Educational efforts to inform patients about PPV and to address misconceptions (e.g., safety, efficacy, Medicare coverage) also may improve vaccination levels.

Improving adolescent preventive care in community health centers

OBJECTIVE

To evaluate implementation of the Guidelines for Adolescent Preventive Services (GAPS) in Community and Migrant Health Centers (CMHCs).

DESIGN

Before and after comparison of health center policy, clinician and adolescent self-report, and chart reviews in 5 CMHCs.

PARTICIPANTS

Eighty-one preintervention and 80 one-year postintervention providers and 318 preintervention and 331 postintervention 14- to 19- year-old adolescent patients being seen for well visits at 5 CMHCs.

INTERVENTION

Health center staff were trained to implement GAPS and were provided resource materials, patient questionnaires, and clinician manuals.

MAIN OUTCOME MEASURES

Delivery of and receipt of preventive services and perceived access to care.

RESULTS

CMHC systems changes were related to stronger leadership commitment to adolescent care. Providers reported high levels of preventive services delivery before and after guideline implementation. After guideline implementation, adolescents reported increases in having discussed prevention content with providers in 19 of 31 content areas, including increased discussion of physical or sexual abuse (10% before to 22% after), sexual orientation (13% to 27%), fighting (6% to 21%), peer relations (37% to 52%), suicide (7% to 22%), eating disorders (11% to 28%), weapons (5% to 22%), depression (16% to 34%), smokeless tobacco (10% to 29%), and immunizations (19% to 48%). Adolescents were also more likely to report knowing where to get reproductive or mental health services and were more likely to have received health education materials. Implementation also increased documentation of recommended screening and counseling in 51 of 79 specific content areas assessed in chart reviews.

CONCLUSION

Implementing GAPS increased the receipt of preventive services at these health centers. Adolescents received more comprehensive screening and counseling, more health education materials, and had greater access to care after implementation. GAPS implementation may help improve the quality of care for adolescents.

The current status of primary prevention in coronary heart disease

During the second part of the twentieth century, research advances caused a substantial decline in the rate of coronary heart disease. The decline lasted from the mid-1960s until the early 1990s and occurred primarily in Western countries. However, an unfavourable trend in coronary heart disease related mortality has gradually developed during the 1990s, with cardiovascular diseases anticipated to remain the main cause of overall mortality for the foreseeable future. The present paper aims at analyzing the current status of the main determinants of population-wide coronary heart disease prevention.

Direct observation of rates of preventive service delivery in community family practice

BACKGROUND

Data on preventive service delivery in primary care practice have been limited by indirect methods of measurement. This study describes directly observed rates of preventive service delivery during outpatient visits to community family physicians.

METHODS

In a multimethod cross-sectional study, research nurses directly observed consecutive patient visits in the offices of 138 family physicians in Northeast Ohio. Patient eligibility for services recommended by the U.S. Preventive Services Task Force was determined from medical record review. Service delivery was assessed by direct observation of outpatient visits. Rates of delivery of specific preventive services were computed. Global summary measures were calculated for health habit counseling, screening, and immunization services.

RESULTS

Among 4,049 visits by established patients with available medical records, wide variation was observed among rates of different preventive services delivered during well-care visits. During illness visits, rates were uniformly low for all preventive services. Counseling services were delivered at only slightly lower rates during illness visits compared to well visits. Patients were up to date on 55% of screening, 24% of immunization, and 9% of health habit counseling services.

CONCLUSION

Rates of preventive service delivery are low. Illness visits are important opportunities to deliver preventive services, particularly health habit counseling, to patients. Preventive service delivery summary scores are useful in providing a patient population perspective on the delivery of preventive services and in focusing attention on delivery of a comprehensive portfolio of services.

Clinician satisfaction with a preventive services implementation trial. The IMPROVE project

OBJECT

To discover how attempts to increase the delivery of preventive services affect clinician satisfaction.

METHODS

The IMPROVE project was a randomized clinical trial conducted in 44 clinics in and around Minneapolis-St. Paul, Minnesota. Personnel were trained in continuous quality improvement techniques to organize preventive services delivery systems. Satisfaction with delivery of these services and with the sponsoring organizations was measured before the intervention (Time 1), at the end of the intervention (Time 2), and 1 year post-intervention (Time 3).

RESULTS

At no time was the intervention associated with a change in the respondents satisfaction with their places of work or with their job roles. Satisfaction with preventive services delivery increased from Time 1 to Time 3 among intervention-clinic respondents. Satisfaction with the IMPROVE project and the efforts of the two managed care organizations to help the clinics deliver preventive services peaked at Time 2 and declined toward baseline at Time 3. Satisfaction with preventive services delivery tended to increase more in the 13 intervention clinics that implemented a preventive services delivery system than in the nine intervention clinics that did not implement a preventive services delivery system (p = 0.15).

CONCLUSIONS

Planned organizational change to create systems for preventive services delivery can be associated with increased clinician satisfaction with the way these services are delivered. However, increased satisfaction with preventive services does not necessarily indicate that service delivery rates have increased.
