Diffusion of the U.S. Preventive Services Task Force recommendations into practice

The Relationships Between State Health Department Practitioners' Perceptions of Organizational Supports and Evidence-Based Decision-Making Skills

OBJECTIVES

Evidence-based decision making (EBDM) allows public health practitioners to implement effective programs and policies fitting the preferences of their communities. To engage in EBDM, practitioners must have skills themselves, their agencies must engage in administrative evidence-based practices (A-EBPs), and leaders must encourage the use of EBDM. We conducted this longitudinal study to quantify perceptions of individual EBDM skills and A-EBPs, as well as the longitudinal associations between the 2.

METHODS

An online survey completed among US state health department practitioners in 2016 and 2018 assessed perceptions of respondents' skills in EBDM and A-EBPs. We used χ2 tests, t tests, and linear regressions to quantify changes over time, differences by demographic characteristics, and longitudinal associations between individual skills and A-EBPs among respondents who completed both surveys (N = 336).

RESULTS

Means of most individual EBDM skills and A-EBPs did not change significantly from 2016 to 2018. We found significant positive associations between changes in A-EBPs and changes in EBDM skill gaps: for example, a 1-point increase in the relationships and partnerships score was associated with a narrowing of the EBDM skill gap (β estimate = 0.38; 95% CI, 0.15-0.61). At both time points, perceived skills and A-EBPs related to financial practices were low.

CONCLUSIONS

Findings from this study can guide the development and dissemination of initiatives designed to simultaneously improve individual and organizational capacity for EBDM in public health settings. Future studies should focus on types of strategies most effective to build capacity in particular types of agencies and practitioners, to ultimately improve public health practice.

Factors Facilitating or Hindering Use of Evidence-Based Diabetes Interventions Among Local Health Departments

OBJECTIVE

The objective of this study was to assess facilitators, barriers, and capacities to use of evidence-based programs and policies (EBPPs) in local health departments (LHDs).

DESIGN

A qualitative study design was used to elicit a contextual understanding of factors. One-hour interviews were conducted among directors and diabetes/chronic disease practitioners from LHDs. A consensus coding approach was used to identify themes.

SETTING AND PARTICIPANTS

Twenty-four participants from 14 Missouri LHDs completed interviews.

RESULTS

Themes were identified as facilitators, barriers, or capacities that enhance EBPP use. Facilitators included awareness of EBPPs, leadership and supervisor support of EBPP use, and facilitators to increase capacity to implement EBPPs. Skills development, targeted messaging, and understanding of evidence-based decision-making (EBDM) terminology were needed. Barriers to EBPPs use were described at the individual, organizational, and interorganizational levels and included community buy-in, limited resources, relevance to partners, and time scarcity. Capacities included the ways LHDs learn about EBPPs, methods that influence the use of EBPPs, and resources needed to sustain EBPPs. Top ways to learn about EBPPs were in-person interactions. Staff meetings, meetings with decision makers, and relevant evidence influenced decision making. Resources needed were funding, organizational capacity, and partnerships. Directors' and practitioners' views differed on type of agency culture that promoted EBPP use, preferences for learning about EBPPs, ways to influence decisions, needs, and barriers to EBPPs.

CONCLUSIONS

These findings can inform future strategies to support uptake of EBPPs in diabetes and chronic disease control in LHDs. LHDs have a good understanding of EBPPs, but subtle differences in perception of EBPPs and needs exist between directors and practitioners. Investment in capacity building and fostering an organizational culture supportive of EBDM were key implications for practice. By investing in employee skill development, LHDs may increase agency capacity. Researchers should use preferred channels and targeted messaging to disseminate findings.

Enhancing evidence-based diabetes and chronic disease control among local health departments: a multi-phase dissemination study with a stepped-wedge cluster randomized trial component

BACKGROUND

The rates of diabetes and prediabetes in the USA are growing, significantly impacting the quality and length of life of those diagnosed and financially burdening society. Premature death and disability can be prevented through implementation of evidence-based programs and policies (EBPPs). Local health departments (LHDs) are uniquely positioned to implement diabetes control EBPPs because of their knowledge of, and focus on, community-level needs, contexts, and resources. There is a significant gap, however, between known diabetes control EBPPs and actual diabetes control activities conducted by LHDs. The purpose of this study is to determine how best to support the use of evidence-based public health for diabetes (and related chronic diseases) control among local-level public health practitioners.

METHODS/DESIGN

This paper describes the methods for a two-phase study with a stepped-wedge cluster randomized trial that will evaluate dissemination strategies to increase the uptake of public health knowledge and EBPPs for diabetes control among LHDs. Phase 1 includes development of measures to assess practitioner views on and organizational supports for evidence-based public health, data collection using a national online survey of LHD chronic disease practitioners, and a needs assessment of factors influencing the uptake of diabetes control EBPPs among LHDs within one state in the USA. Phase 2 involves conducting a stepped-wedge cluster randomized trial to assess effectiveness of dissemination strategies with local-level practitioners at LHDs to enhance capacity and organizational support for evidence-based diabetes prevention and control. Twelve LHDs will be selected and randomly assigned to one of the three groups that cross over from usual practice to receive the intervention (dissemination) strategies at 8-month intervals; the intervention duration for groups ranges from 8 to 24 months. Intervention (dissemination) strategies may include multi-day in-person workshops, electronic information exchange methods, technical assistance through a knowledge broker, and organizational changes to support evidence-based public health approaches. Evaluation methods comprise surveys at baseline and the three crossover time points, abstraction of local-level diabetes and chronic disease control program plans and progress reports, and social network analysis to understand the relationships and contextual issues that influence EBPP adoption.

General Practitioners as Agents of Health Risk Behaviour Change: Opportunities for Behavioural Science in Patient Smoking Cessation

General practitioners have been suggested as occupying a position in the community that offers considerable potential for reducing the prevalence of health risk behaviours. Green, Eriksen, and Schor (1988) have proposed that if general practitioners are to effectively adopt a role in modifying patient health risk behaviours, a number of prerequisite conditions must be met. Using the model proposed by Green et al., this paper reviews the literature to describe the circumstances under which general practitioners currently practise this role. The review focuses on the circumstances relating to practitioner modification of one patient health risk behaviour: smoking. Research detailing the extent of practitioner involvement in the modification of this risk behaviour is also reviewed. The paper concludes by discussing the opportunities available for behavioural scientists to facilitate general practitioners' adoption of a role in patient smoking cessation.

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.

Barriers to evidence-based decision making in public health: a national survey of chronic disease practitioners

OBJECTIVE

Existing knowledge of evidence-based chronic disease prevention is not systematically disseminated or applied. This study investigated state and territorial chronic disease practitioners' self-reported barriers to evidence-based decision making (EBDM).

METHODS

In a nationwide survey, participants indicated the extent to which they agreed with statements reflecting four personal and five organizational barriers to EBDM. Responses were measured on a Likert scale from 0 to 10, with higher scores indicating a larger barrier to EBDM. We analyzed mean levels of barriers and calculated adjusted odds ratios for barriers that were considered modifiable through interventions.

RESULTS

Overall, survey participants (n=447) reported higher scores for organizational barriers than for personal barriers. The largest reported barriers to EBDM were lack of incentives/rewards, inadequate funding, a perception of state legislators not supporting evidence-based interventions and policies, and feeling the need to be an expert on many issues. In adjusted models, women were more likely to report a lack of skills in developing evidence-based programs and in communicating with policy makers. Participants with a bachelor's degree as their highest degree were more likely than those with public health master's degrees to report lacking skills in developing evidence-based programs. Men, specialists, and individuals with doctoral degrees were all more likely to feel the need to be an expert on many issues to effectively make evidence-based decisions.

CONCLUSIONS

Approaches must be developed to address organizational barriers to EBDM. Focused skills development is needed to address personal barriers, particularly for chronic disease practitioners without graduate-level training.

Factors associated with discipline counseling for parents of infants and young children

OBJECTIVE

The aim of this study was to identify and better understand the factors associated with discipline counseling at health visits and how parents' needs for discipline counseling are being met.

METHODS

Cross-sectional data analyses from the 2000 National Survey of Early Childhood Health. Participants were 1216 parents of children aged between 10 and 35 months. Main outcome measures were parents' reports that their health care provider discussed discipline practices with them in the previous year, and if not, whether this would have been helpful (an unmet need).

RESULTS

Discipline counseling was more common when the health care provider discussed other developmental and psychosocial topics, did a developmental assessment, received higher ratings of family centered care and provided longer visits, and when parents indicated having the opportunity to ask all their questions. However, parents who reported less support for child rearing and parents who reported greater use of spanking were less likely to receive discipline counseling. Spanish-speaking Hispanic parents and parents who reported less support were more likely to report an unmet need for discipline counseling. Higher income respondents were less likely to report an unmet need for discipline counseling.

CONCLUSION

Discipline counseling at health visits is associated with a family-centered orientation and the delivery of other developmental and psychosocial services. However, many parents who might have benefited from discipline counseling were less likely to receive it and more likely to report this as an unmet need. These data suggest that discipline counseling may be more accurately tailored to parents most likely to benefit.

Healthy and fit for prevention: the influence of clinician health and fitness on promotion of healthy lifestyles during health supervision visits

To understand the relationship between pediatricians' personal health and the delivery of pediatric preventive care, Illinois pediatricians were surveyed by mail. Responses from 387 pediatricians (55% response rate) regarding personal characteristics, their practice, and perceptions about preventive care patterns for children aged 2 through 10 years and management of overweight children were analyzed. Overall, 28% of pediatricians were healthy and fit (excellent/very good health and extremely/ very fit), 40% were either healthy or fit, and 33% were neither healthy nor fit. In logistic regression models controlling for personal and practice characteristics, healthy and fit pediatricians (vs neither healthy nor fit pediatricians) more routinely provided recommended care on child diet (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.6-6.2) and physical activity (OR, 3.2; 95% CI, 1.6-6.3) and assessed television time (OR, 4.4; 95% CI, 2.0-10.1). Pediatricians who were either healthy or fit (vs pediatricians who were neither healthy nor fit) more often assessed television time. Therefore, clinician health influenced application of preventive care.

The effect of disseminating evidence-based interventions that promote physical activity to health departments

OBJECTIVES

We explored the effect of disseminating evidence-based guidelines that promote physical activity on US health department organizational practices in the United States.

METHODS

We implemented a quasi-experimental design to examine changes in the dissemination of suggested guidelines to promote physical activity (The Guide to Community Preventive Services) in 8 study states; the remaining states and the Virgin Islands served as the comparison group. Guidelines were disseminated through workshops, ongoing technical assistance, and the distribution of an instructional CD-ROM. The main evaluation tool was a pre- and postdissemination survey administered to state and local health department staffs (baseline n=154; follow-up n=124).

RESULTS

After guidelines were disseminated through workshops, knowledge of and skill in 11 intervention-related characteristics increased from baseline to follow-up. Awareness-related characteristics tended to increase more among local respondents than among state participants. Intervention adoption and implementation showed a pattern of increase among state practitioners but findings were mixed among local respondents.

CONCLUSIONS

Our exploratory study provides several dissemination approaches that should be considered by practitioners as they seek to promote physical activity in the populations they serve.

Methodologic challenges in disseminating evidence-based interventions to promote physical activity

During the past decade, numerous intervention studies have been published on the effectiveness of programs to promote active living; however, few studies have addressed the dissemination of effective physical activity interventions. Both community settings and healthcare settings are important locations for dissemination of evidence-based programs and policies. A major gap in the existing literature involves the appropriate methodologic approaches for planning, evaluating, and reporting on dissemination efforts for effective and promising interventions in these locations. To address this gap, two hypothetical dissemination studies are presented: a quasi-experimental study of local health agencies (Scenario 1) and a group-randomized trial of clinical practices (Scenario 2). These studies help to elucidate the barriers and opportunities for implementing evidence-based physical activity interventions across different settings. Based on the scenarios, the existing literature, and the authors' experience, dissemination challenges that researchers and practitioners may experience (i.e., issues of design, measures of outcomes and external validity, the balance between fidelity and adaptation to local settings, and the review and funding of dissemination science) are discussed. Researchers, practitioners, and policymakers are invited to address the issues outlined in this article in order to bridge the gap between the generation of new knowledge on efficacious physical activity interventions and widespread application of these approaches in community and clinical settings.

Increasing the screening and counseling of adolescents for risky health behaviors: a primary care intervention

OBJECTIVE

To determine whether a systems intervention for primary care providers resulted in increased preventive screening and counseling of adolescent patients, compared with the usual standard of care.

METHODS

The intervention was conducted in 2 outpatient pediatric clinics; 2 other pediatric clinics in the same health maintenance organization served as comparison sites. The intervention was implemented in 2 phases: first, pediatric primary care providers attended a training workshop (N = 37) to increase screening and counseling of adolescents in the areas of tobacco, alcohol, drugs, sexual behavior, and safety (seatbelt and helmet use). Second, screening and charting tools were integrated into the intervention clinics. Providers in the comparison sites (N = 39) continued to provide the usual standard of care to their adolescent patients. Adolescent reports were used to assess changes in provider behavior. After a well visit, 13- to 17-year olds (N = 2628) completed surveys reporting on whether their provider screened and counseled them for risky behavior.

RESULTS

Screening and counseling rates increased significantly in each of the 6 areas in the intervention sites, compared with rates of delivery using the usual standard of care. Across the 6 areas combined, the average screening rate increased from 58% to 83%; counseling rates increased from 52% to 78%. There were no significant increases in the comparison sites during the same period. The training component seems to account for most of this increase, with the tools sustaining the effects of the training.

CONCLUSIONS

The study offers strong support for an intervention to increase clinicians' delivery of preventive services to a wide age range of adolescent patients.

Organizational predictors of adherence to ambulatory care screening guidelines

OBJECTIVE

The purpose of this study was to identify hospital organizational characteristics consistently associated with adherence to multiple clinical practice guidelines (CPGs). We examined the relationship between organizational and patient population characteristics and adherence to three screening CPGs implemented throughout the Veterans Health Administration (VHA).

MATERIALS AND METHODS

The study included 114 acute care facilities. Three sources of data were used: 1998 American Hospital Association data, VHA External Peer Review Program data for 1998 and 1999, and the 1999 Veterans Satisfaction Survey. Organizational characteristics likely to affect adherence with the CPGs were classified into five conceptual domains (clinical emphasis, operational capacity, patient population, professionalism, and urbanicity). Organizational characteristics were ranked, based on their standardized beta coefficients in bivariate logistic regressions predicting the likelihood of adherence. Within-domain multivariable logistic analyses assessed the robustness of individual predictors of CPG adherence, controlling for other organizational factors within the same domain.

RESULTS

Overall, 46 of 48 relationships in the bivariate logistic analyses were significant, and 43 of these remained significant in the within-domain multivariate analyses. The relative rankings of the variables as predictors of CPG adherence within conceptual domains were also quite consistent.

CONCLUSIONS

Strong evidence was found for the importance of specific organizational factors, including mission, capacity, professionalism, and patient population characteristics that influence CPG adherence in a large multi-institutional sample involving multiple provider practices. Research and programs to improve adherence to CPGs and other quality improvement activities in hospitals should incorporate these organizational factors.

Increasing cervical cancer screening among underserved women in a large urban county health system: can it be done? What does it take?

BACKGROUND

Further reduction in avoidable cervical cancer morbidity and mortality may require system-wide, integrated approaches implemented in the public health facilities serving the nation's indigent and minority women.

OBJECTIVES

Report on the evaluation of a 5-year demonstration project testing a multicomponent (provider, system, and patient) intervention to increase cervical cancer screening among women who receive their health care through the Los Angeles County Department of Health Services, the second largest County Health Department in the nation.

MATERIALS AND METHODS

A longitudinal nonequivalent control group design was utilized. Data were collected during a baseline (no intervention) year and 2.5 years of intervention. A large hospital, one feeder Comprehensive Health Centers (CHC), and three of the health center's feeder Public Health Centers (PHC) received the intervention. Another hospital, CHC and its three feeder PHCs (matched on size, patient characteristics, and range of services provided) served as comparison sites. Independent random samples of patients 18 years and older were drawn annually at each site (n = 18,642). The outcome measure was a receipt of a Papanicolaou smear during a 9-month period.

RESULTS

At the Hospital and CHC levels a statistically significant intervention effect was observed after controlling for baseline screening rates and case mix. No intervention effect was observed at the PHCs.

CONCLUSION

An intensive multicomponent intervention can increase cervical cancer screening in a large, urban, County health system serving a low-income minority population of under screened women. Retention of program elements in the postresearch phase, and the difficulties and importance of conducting this type of research, is described.

Primary care-based smoking interventions

The primary care setting is an important place for promoting smoking cessation. Randomized clinical trials (RCTs) testing the effect of brief smoking interventions and comprehensive programs delivered in a primary care setting present excellent evidence that such interventions significantly increase patients' smoking cessation rates and that as the dose of intervention increases, the effect increases. Unfortunately, despite widespread dissemination of preventive services guidelines and positive physician attitudes towards such services, the current level of delivery of smoking cessation intervention by physicians in real-world settings is not high, making this a major research and public health concern. Interventions to increase the rate of implementation provider-delivered brief smoking interventions can be grouped broadly into: provider education; clinical systems and procedures (e.g., screening and tracking of patients); and organizational policy (e.g., reimbursement, coverage, performance measures). Given the significant effect that primary care-based interventions can have on smoking cessation, it is important to investigate methods to increase their rate of delivery and their effect. Examples of research to motivate to intervene questions include: what are the best incentives or combination of incentives for physicians? What are the most effective strategies to remind providers to intervene? How can each of these be best implemented in different types of settings and systems? How can a stepped-care and patient-treatment matching model be used? The study of factors such as reimbursement policies and covered benefits do not lend themselves well to tightly-controlled randomized trials. Therefore, use of quasi-experimental designs, and application of qualitative strategies are needed. These designs represent a different challenge to the research community.

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.

Improving the delivery of adolescent clinical preventive services through skills-based training

OBJECTIVE

To examine the efficacy of skills-based training workshops on primary care providers' screening and counseling practices with adolescents during routine outpatient well visits.

DESIGN

Sixty-three primary care providers in outpatient pediatric departments within a managed health care organization participated in two 4-hour workshops on clinical preventive services for adolescents. The workshops focused on adolescent health, confidentiality, screening, and anticipatory guidance/brief counseling for 5 risk behaviors including: helmet and seatbelt use, tobacco use, alcohol use, and sexual behavior. A pre/posttest design was used to assess clinicians' screening and counseling practices during the pretraining and posttraining periods. Independent adolescent reports of clinicians' practices were obtained from 2 samples of 14- to 16-year-old adolescents immediately after their routine well visit in the outpatient clinics. One sample of adolescents reported during a pretraining period and a separate sample reported during a period after the training.

RESULTS

Adolescent reports indicated that after the training workshops, the average percentage of adolescents screened by their primary care providers increased significantly for seatbelt use (from mean 38% to 56%), helmet use (from mean 27% to 45%), tobacco use (from mean 64% to 76%), alcohol use (from mean 59% to 76%), and sexual behavior (from mean 61% to 75%). Additionally, the average percentage of adolescents offered brief counseling by their clinicians increased significantly after training in the areas of seatbelt use (from mean 36% to 51%), helmet use (from mean 25% to 43%), and sexual behavior (from mean 42% to 58%). Improvement after the training in brief counseling for tobacco use was marginally significant (from mean 60% to 69%) and for alcohol use was not significant, although there was an increase. Clinicians also significantly increased their discussion of the limits of confidentiality with their adolescent patients after the training workshops (from mean 32% to 45%).

CONCLUSIONS

This study offers strong support for the efficacy of skills-based training for primary care providers as a method for increasing screening and counseling practices with adolescents. The present findings suggest that with appropriate skills-based training, practicing clinicians can implement several of the national guidelines that direct them to provide preventive services for multiple behaviors in a routine outpatient visit. Screening and counseling in these visits are important in the early identification, detection, and prevention of behaviors associated with the primary adolescent morbidities and mortalities. Thus, enhancing the delivery of clinical preventive services is an important step in the prevention of untoward health outcomes for youth.

A computerized tool for evaluating the effectiveness of preventive interventions

In identifying appropriate strategies for effective use of preventive services for particular settings or populations, public health practitioners employ a systematic approach to evaluating the literature. Behavioral intervention studies that focus on prevention, however, pose special challenges for these traditional methods. Tools for synthesizing evidence on preventive interventions can improve public health practice. The authors developed a literature abstraction tool and a classification for preventive interventions. They incorporated the tool into a PC-based relational database and user-friendly evidence reporting system, then tested the system by reviewing behavioral interventions for hypertension management. They performed a structured literature search and reviewed 100 studies on behavioral interventions for hypertension management. They abstracted information using the abstraction tool and classified important elements of interventions for comparison across studies. The authors found that many studies in their pilot project did not report sufficient information to allow for complete evaluation, comparison across studies, or replication of the intervention. They propose that studies reporting on preventive interventions should (a) categorize interventions into discrete components; (b) report sufficient participant information; and (c) report characteristics such as intervention leaders, timing, and setting so that public health professionals can compare and select the most appropriate interventions.

Adopting immunization recommendations: a new dissemination model

OBJECTIVE

This paper presents a new approach for understanding factors related to physician adoption of clinical guidelines, using children's vaccine recommendations as a case study.

METHODS

The model traces sequential steps, from awareness to agreement to adoption and, finally, adherence to the guideline. Movement through these stages can be catalyzed or retarded by many influences, grouped into two major categories: environmental characteristics of the physician's practice, and information characteristics of the guideline. Environmental characteristics include sociocultural factors, professional characteristics, and practice organization factors. Information characteristics include the guideline's relative advantage, complexity, and compatibility with existing guidelines and protocols, as well as mechanisms of guideline dissemination.

IMPLICATIONS

This model can be used to identify characteristics that will likely impede or facilitate guideline adoption, and to focus dissemination efforts on key issues.

The impact of legislatively imposed practice guidelines on cesarean section rates: the Florida experience

Florida legislation implemented in the fall of 1992, unique in the nation, mandated that practice guidelines regarding cesarean section deliveries be disseminated to obstetric physicians. The law also required that peer review boards at hospitals be established to review cesarean deliveries and that the exact dates of implementation of the guidelines be reported to a state agency. To determine the impact of the legislation, we conducted a retrospective analysis of 366,246 total live births occurring in Florida hospitals during 1992 and 1993, before and after formal hospital certification of the implementation of the guidelines. Changes in primary and repeat cesarean rates were analyzed for 108 independent groups of births, controlling for the mother's age, race, payment source, and the timing of the implementation of the guidelines at hospitals. The guideline certification program did not accelerate the consistent but gradual downward trend in cesarean births which had already been evident in the three prior years. The data do suggest that the guideline program may have affected repeat cesareans more than primary cesareans, especially in the first quarter of 1993, immediately after the hospital certification period. Reductions in repeat cesareans involved both Medicaid and commercially insured births, whereas reductions in primary cesareans were found almost exclusively within commercially insured mothers, where the existing rates are highest. Although births with a prior cesarean represent only 12.5% of all births, significant decreases in repeat cesareans were found in groups representing 72.6% of this population. By comparison, significant decreases in primary cesareans were found in groups representing only 36.5% of the births without a prior cesarean. The date of guideline implementation reported by hospitals was not related to any systematic change in observed cesarean section rates. We concluded that the mere dissemination of practice guidelines by a state agency may not achieve either the magnitude or the specificity of the results desired without an explicit and thorough guideline implementation program. Blunt legislative mandates may be ineffective when multiple initiatives are already achieving desired outcomes.

Community organization to promote breast cancer screening ordering by primary care physicians

Community organization has been viewed as a promising approach to changing preventive behaviors. We evaluated the impact of community organization strategies to promote breast cancer screening ordering by primary care physicians in Washington State. Physicians practicing in two intervention and two control communities were surveyed by mail pre-intervention (1989) and post-intervention (1993). Intervention activities targeting the health care sector included the formation of local physician planning groups, a series of informational mailings, medical office staff training sessions, and reminder system support. There were no significant post-intervention differences in the self-reported mammography ordering of physicians practicing in the intervention and control areas. Over the four-year study period, the proportions of physicians who ordered regular mammography increased by 36%. By 1993, over 80% of the respondents routinely used mammographic screening. Concerns about the high price of mammograms and inadequate insurance coverage were significantly reduced over time in both community pairs. Also, use of patient reminder systems increased significantly between 1989 and 1993. Secular trends resulting from diffusion of strategies to promote mammography were responsible for increases in physician ordering of the procedure. Year 2000 goals for breast cancer screening use by physicians may already have been met in some communities.

Smoking status as the new vital sign: effect on assessment and intervention in patients who smoke

OBJECTIVE

To assess the effect of expanding the vital signs to include smoking status.

DESIGN

We prospectively conducted exit interviews with patients at a general internal medicine clinic in Madison, Wisconsin, during a 16-month period from 1991 to 1993.

METHODS

Patients were surveyed briefly before (N = 870) and after (N = 994) the implementation of a simple institutional change in clinical practice. This change involved training the staff in how to use progress notepaper with a vital sign stamp that included smoking status (current, former, or never) along with the traditional vital signs. Included in the survey were questions about whether the patient smoked, whether the patient was asked that day about smoking status (by a clinician or other staff), and, for smokers, whether they were urged to quit smoking and given specific advice on how to do so.

RESULTS

After expansion of the vital signs, patients were much more likely to report inquiries about their smoking status on the day of a clinic visit (an increase from approximately 58% at baseline to 81% at intervention; P < 0.0001). The vital sign intervention was associated with significant increases in the percentage of smokers who reported that their clinician advised them that day to quit smoking (from approximately 49% at baseline to 70% during the intervention; P < 0.01) and in the percentage who reported that their clinician gave them specific advice that day on how to stop smoking (from approximately 24% at baseline to 43% during the intervention; P < 0.01).

CONCLUSION

Expanding the vital signs to include smoking status was associated with a dramatic increase in the rate of identifying patients who smoke and of intervening to encourage and assist with smoking cessation. This simple, low-cost intervention may effectively prompt clinicians to inquire about use of tobacco and offer recommendations to smokers.

Trends in cesarean section use in California, 1983 to 1990

OBJECTIVE

Our aim was to assess recent trends in cesarean section use in California.

STUDY DESIGN

California discharge abstract data on hospital deliveries in 1983 through 1990 (379,759 to 587,508 annual deliveries) were used to analyze time trends by indication, age, race, and payment source.

RESULTS

California cesarean section rates increased annually from 21.8% in 1983 to 25.0% in 1987 and then decreased to 22.7% by 1990. Similar patterns were noted for all age and race or ethnicity groups. Primary cesarean section rates increased from 15.2% in 1983 to 17.9% in 1987, then decreased to 16.2% by 1990. Declines in repeat cesarean section rates continued throughout 1983 through 1990, accelerating after 1987. For both primary and repeat cesarean section rates, time trends after mid-1987 were significantly different than those for 1983 to 1987.

CONCLUSION

After increasing from 1983 to 1987, California cesarean section rates declined from 1988 to 1990. Existing payment source differences in cesarean section use increased in magnitude from 1983 to 1990, with privately insured women consistently having the highest cesarean section rates.

Long-term success with the national health objective for influenza vaccination: an institution-wide model

PURPOSE

To assess the long-term effectiveness of an influenza vaccination program.

SETTING

725-bed university-affiliated VA teaching hospital providing care to over 35,000 outpatients.

DESIGN AND SUBJECTS

500 randomly selected outpatients were surveyed following each immunization season using a validated, self-administered, postcard questionnaire.

PROGRAM DESCRIPTION

The institution-wide program, designed to function automatically and to be independent of physician initiative, emphasizes organizational and patient-oriented educational strategies: 1) a hospital policy allowing nurses to vaccinate without a physician's order; 2) a walk-in flu shot clinic; 3) reminders on clinic progress notes; and 4) an educational mailing to all outpatients. The program was initiated in 1987 and has been maintained for each subsequent immunization season.

RESULTS

The response rate was over 75% for each of the four years in which there were two mailings. The response rate for 1988-1989, in which there were three mailings, was over 85%. Approximately 70% of the respondents were at high risk for influenza and its complications. Vaccination rates for these high-risk outpatients have been sustained at over 58% for each immunization season.
