Making "time" for preventive services

Do nurse practitioners make a difference in provision of health counseling in hospital outpatient departments?

PURPOSE

This study examined whether nurse practitioners (NPs) had any impact on the type and amount of health counseling provided during patient visits to hospital outpatient departments (OPDs).

DATA SOURCES

This is a secondary data analysis of the National Hospital Ambulatory Medical Care Survey from 1997 to 2000. Only patient visits to hospital OPDs were included. Rates of health counseling provided at patient visits involving an NP were compared with those without an NP. Adjusted odds ratio was reported separately for each type of health counseling provided at patient visits for nonillness care, for chronic problems, and for acute problems.

CONCLUSIONS

Health counseling for diet, exercise, human immunodeficiency virus (HIV) and sexually transmitted disease (STD) prevention, tobacco use, and injury prevention are more likely to be provided at nonillness care visits involving an NP than at those not involving an NP. The presence of an NP is associated not only with higher rates of counseling for diet, exercise, and tobacco use provided at patient visits for chronic problems but also with higher rates of counseling for diet and HIV/STD prevention provided at patient visits for acute problems.

IMPLICATIONS FOR PRACTICE

This study indicates an important role NPs can play in providing preventive services in outpatient hospital departments. The findings reflect the emphasis of the NP education on health counseling and patient education in clinical practice.

Health promotion in physician organizations: results from a national study

BACKGROUND

Health promotion programs can be effective in improving the delivery of clinical preventive services and in improving population health; however, the availability of health promotion programs offered through physician organizations, such as medical groups and independent practice associations, are largely unknown.

METHODS

This research uses data from the National Study of Physician Organizations and the Management of Chronic Illness, conducted by the University of California, Berkeley, to document the extent to which physician organizations offer health promotion programs. Of 1587 physician organizations nationally with 20 or more physicians, 1104 participated, for a response rate of 70%.

RESULTS

Overall, 60% of physician organizations offer at least one health promotion program targeting one or more of eight areas: prenatal education (42%), smoking cessation (39%), nutrition (39%), weight loss (34%), health risk assessments (25%), stress management (25%), substance abuse (20%), and sexually transmitted disease prevention (16%). Factors positively associated with offering health promotion programs include the following: outside reporting of quality measures, public recognition for quality measures, clinical information technology systems, being a medical group, and ownership by a hospital or health plan.

CONCLUSIONS

Physician organizations in the United States have a long way to go in offering these important programs to their patients. However, our findings also suggest that health plans, purchasers, and policymakers can play a positive role in increasing the use of these programs. By offering recognition and incentives for quality improvement, and by funding the expansion of information technology, the healthcare community can encourage and enable physician organizations to increase the availability of health promotion programs nationally.

Interventions for patients, providers, and health care organizations

Clinicians and the organizations within which they practice play a major role in enabling patient participation in cancer screening and ensuring quality services. Guided by an ecologic framework, the authors summarize previous literature reviews and exemplary studies of breast, cervical, and colorectal cancer screening intervention studies conducted in health care settings. Lessons learned regarding interventions to maximize the potential of cancer screening are distilled. Four broad lessons learned emphasize that multiple levels of factors-public policy, organizational systems and practice settings, clinicians, and patients-influence cancer screening; that a diverse set of intervention strategies targeted at each of these levels can improve cancer screening rates; that the synergistic effects of multiple strategies often are most effective; and that targeting all components of the screening continuum is important. Recommendations are made for future research and practice, including priorities for intervention research specific to health care settings, the need to take research phases into consideration, the need for studies of health services delivery trends, and methods and measurement issues.

Eliminating disparities: empowering health promotion within preventive medicine

The estimated 800,000 U.S. deaths in 1990 related to behavioral decisions challenge physicians to better assist behavioral change through expanded health promotion activities. Based on the format guidelines of this special issue, this brief paper first examines the current and optimal roles of health promotion within Preventive Medicine, including five physician roles for improving modifiable public health-risk behavior burdens: (1) preventive services clinician, (2) health promotion researcher, (3) educator-communicator, (4) systems manager, and (5) health promotion advocate. After presenting a new vision statement, this paper proceeds to discuss the opportunities and barriers, including system, clinician-office, and patient factors, to attaining this new vision of empowering health promotion within Preventive Medicine. Finally, all physicians are invited to engage in a threefold strategic plan for change through at least one of five action items: (1) health promotion advocacy, (2) health promotion research, (3) public communication, (4) protocol dissemination and implementation, and (5) Preventive Medicine training.

Factors associated with condom use among at-risk women students and nonstudents seen in managed care

OBJECTIVES

Sexually transmitted diseases (STD) research has focused on high-risk populations such as STD clinic patients and college students. This report examines predictors of unprotected sex among nonstudent women seen in primary care.

STUDY DESIGN

Data are taken from the baseline survey of an intervention trial testing tailored print materials to encourage condom use.

POPULATION

Eligible women were identified from automated databases of two managed care organizations and were ages 18-25, unmarried, heterosexually active in the prior 6 months, and not in a long-term monogamous relationship.

OUTCOMES

The frequency of and relative contribution of risk behaviors to occurrences of unprotected vaginal sex were compared among non-full-time students (n=711) and full-time students (n=390).

RESULTS

STD risk behaviors were prevalent and had similar associations with unprotected sex in both subsamples. Older age, using hormonal or no usual contraception, and having a "primary" partner increased unprotected sex; partner approval of condoms and having bought or carried condoms decreased unprotected sex.

CONCLUSION

While sexually active single women seen in primary care perceive themselves at low STD risk, their risk profiles are similar to those of higher risk populations. Clinic-based interventions that include proactive identification of at-risk women and systems for encouraging safer sex practices are needed.

Primary care: is there enough time for prevention?

OBJECTIVES

We sought to determine the amount of time required for a primary care physician to provide recommended preventive services to an average patient panel.

METHODS

We used published and estimated times per service to determine the physician time required to provide all services recommended by the US Preventive Services Task Force (USPSTF), at the recommended frequency, to a patient panel of 2500 with an age and sex distribution similar to that of the US population.

RESULTS

To fully satisfy the USPSTF recommendations, 1773 hours of a physician's annual time, or 7.4 hours per working day, is needed for the provision of preventive services.

CONCLUSIONS

Time constraints limit the ability of physicians to comply with preventive services recommendations.

Screening for colorectal cancer on the front line

OBJECTIVE

The aim of this study was to assess knowledge, beliefs, and practices of primary care clinicians regarding colorectal cancer screening.

METHODS

We surveyed 77 primary care providers in six clinics in central Massachusetts to evaluate several factors related to colorectal cancer screening.

RESULTS

Most agreed with guidelines for fecal occult blood test (97%) and sigmoidoscopy (87%), which were reported commonly as usual practice. Although the majority (86%) recommended colonoscopy as a colorectal cancer screening test, it was infrequently reported as usual practice. Also, 36% considered barium enema a colorectal cancer screening option, and it was rarely reported as usual practice. Despite lack of evidence supporting effectiveness, digital rectal examinations and in-office fecal occult blood test were commonly reported as usual practice. However, these were usually reported in combination with a guideline-endorsed testing option. Although only 10% reported that fecal occult blood test/home was frequently refused, 60% reported sigmoidoscopy was. Frequently cited patient barriers to sigmoidoscopy compliance included fear the procedure would hurt and that patients assume symptoms occur if there is a problem. Perceptions of health systems barriers to sigmoidoscopy were less strong.

CONCLUSIONS

Most providers recommended guideline-endorsed colorectal cancer screening. However, patient refusal for sigmoidoscopy was common. Results indicate that multiple levels of intervention, including patient and provider education and systems strategies, may help increase prevalence.

Participant reactions to a computerized telephone system for nutrition and exercise counseling

This paper reports on an evaluation of the reactions of participants in a computer-controlled telephone conversation system (telephone-linked care, TLC) designed to offer nutrition and exercise counseling. After 6 months in the study, subjects were asked a series of questions about their opinions of the TLC system, including overall satisfaction and the system's helpfulness. One hundred and ninety individuals completed the attitude survey. On a scale of 0-100, respondents rated the overall satisfaction and helpfulness of the system at 63.6 and 62.3. Subjects using the nutrition counseling version of TLC rated it significantly higher on satisfaction (73.0 versus 52.4) and helpfulness (70.3 versus 53.7) than did subjects using the exercise version. Satisfaction and helpfulness were correlated with perceived usability, amount of contact, realism, and credibility (P < 0.01). Multivariate analyses showed that treatment group and number of calls made accounted for the greatest amount of variance in ratings of satisfaction and helpfulness. The findings suggest that the amount of contact with this technology, reflected by the number of calls, and the treatment group, nutrition or exercise, were significant predictors of reported satisfaction and perceived helpfulness of the system.

Primary care for elderly people: why do doctors find it so hard?

PURPOSE

Many primary care physicians find caring for elderly patients difficult. The goal of this study was to develop a detailed understanding of why physicians find primary care with elderly patients difficult.

DESIGN AND METHODS

We conducted in-depth interviews with 20 primary care physicians. Using an iterative approach based on grounded theory techniques, a multidisciplinary team analyzed the content of the interviews and developed a conceptual model of the difficulty.

RESULTS

Three major domains of difficulty emerged: (i) medical complexity and chronicity, (ii) personal and interpersonal challenges, and (iii) administrative burden. The greatest challenge occurred when difficulty in more than one area was present. Contextual conditions, such as the practice environment and the physician's training and personal values, shaped the experience of providing care and how difficult it seemed.

IMPLICATIONS

Much of the difficulty participants experienced could be facilitated by changes in the health care delivery system and in medical education. The voices of these physicians and the model resulting from our analysis can inform such change.

Physician smoking-cessation actions: are they dependent on insurance coverage or on patients?

BACKGROUND

Despite good evidence that their smoking-cessation actions can be very effective, physicians have not consistently used the 5A actions (being asked, advised, assessed, assisted, and arranged) recommended in the U.S. Public Health Service tobacco guidelines. We tested the hypothesis that the introduction of coverage for smoking-cessation pharmacotherapy by the health plans covering most of the population in one region would increase physician use of 5A's.

METHODS

A cohort of smoking members of two health plans was surveyed before and after the introduction of coverage for smoking cessation. A total of 1560 current smokers with a physician visit in the last year responded to both surveys. The key outcome measures were smoker reports of the guideline 5As for smoking-cessation support during the last physician visit.

RESULTS

There were small significant absolute percentage increases only for reports of being assessed (+4.9%, p=0.01) and assisted (set quit date +6.5%, p=0.0004); encouraged to use medications (+8.8%, p=0.03); and given a prescription (+8.6%, p=0.0005). However, these increases were limited to smokers reporting awareness of the coverage, asking for quitting help, or both.

CONCLUSION

Coverage for pharmacotherapy alone appears to have had no effect on physician behavior beyond that stimulated by smokers who were aware of the coverage, perhaps because they raised the issue. More research is needed on this suggestion that patients create physician behavior change.

Barriers to initiating depression treatment in primary care practice

OBJECTIVE AND DESIGN

This study used qualitative and quantitative methods to examine the reasons primary care physicians and nurses offered for their inability to initiate guideline-concordant acute-phase care for patients with current major depression.

PARTICIPANTS AND SETTING

Two hundred thirty-nine patients with 5 or more symptoms of depression seeing 12 physicians in 6 primary care practices were randomized to the intervention arm of a trial of the effectiveness of depression treatment. Sixty-six (27.6%) patients identified as failing to meet criteria for guideline-concordant treatment 8 weeks following the index visit were the focus of this analysis.

METHODS

The research team interviewed the 12 physicians and 6 nurse care managers to explore the major reasons depressed patients fail to receive guideline-concordant acute-phase care. This information was used to develop a checklist of barriers to depression care. The 12 physicians then completed the checklist for each of the 64 patients for whom he or she was the primary care provider. Physicians chose which barriers they felt applied to each patient and weighted the importance of the barrier by assigning a total of 100 points for each patient. Cluster analysis of barrier scores identified naturally occurring groups of patients with common barrier profiles.

RESULTS

The cluster analysis produced a 5-cluster solution with profiles characterized by patient resistance (19 patients, 30.6%), patient noncompliance with visits (15 patients, 24.2%), physician judgment overruled the guideline (12 patients, 19.3%), patient psychosocial burden (8 patients, 12.9%), and health care system problems (8 patients, 12.9%). The physicians assigned 4,707 (75.9%) of the 6,200 weighting points to patient-centered barriers. Physician-centered barriers accounted for 927 (15.0%) and system barriers accounted for 566 (9.1%) of weighting points. Twenty-eight percent of the patients not initiating guideline-concordant acute-stage care went on to receive additional care and met criteria for remission at 6 months, with no statistical difference across the 5 patient clusters.

CONCLUSIONS

Current interventions fail to address barriers to initiating guideline-concordant acute-stage care faced by more than a quarter of depressed primary care patients. Physicians feel that barriers arise most frequently from factors centered with the patients, their psychosocial circumstances, and their attitudes and beliefs about depression and its care. Physicians less frequently make judgments that overrule the guidelines, but do so when patients have complex illness patterns. Further descriptive and experimental studies are needed to confirm and further examine barriers to depression care. Because few untreated patients improve without acute-stage care, additional work is also needed to develop new intervention components that address these barriers.

Barriers to screening for colorectal cancer

Rapidly growing interest in colon cancer screening is a crucial first step to identifying and reducing many of the barriers that impede population screening for this common disease. Promoting screening demands health care policy change to increase the percentage of Americans with insurance coverage that includes a colon cancer screening benefit. A systematic approach to screening with invitations that come from a clinician are likely to be the most effective way to prompt more individuals to be screened. Awareness campaigns and patient educational aids, including decision tools, implemented in multiple sites, such as worksites, community centers, health care systems, and physician offices, increase the percent of eligible Americans who understand their personal risk, the need for screening, and the options available to them.

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.

How do residents prioritize smoking cessation for young "high-risk" women? Factors associated with addressing smoking cessation

BACKGROUND

Sixty-seven percent of physicians report advising their smoking patients to quit. Primary care residents' priorities for preventive health for a young "high-risk" female are unknown. Factors related to residents addressing smoking also need examining.

METHODS

One hundred residents completed a survey about preventive health issues for a woman in her 20s "who leads a high-risk lifestyle." Residents indicated which topics they would address, and the likelihood that they would address each of 12 relevant preventive health topics, their outcome expectancies that the patient would follow their advice on each topic, their confidence that they could address the topic, and perceived barriers for addressing the topic.

RESULTS

Residents listed STD prevention most frequently. Drug use and smoking cessation were second and third most frequently listed. Residents who believed that the patient would follow their advice were more likely to list smoking cessation than residents who had lower outcome expectancies for that patient. Higher barriers were negatively related to addressing smoking cessation.

CONCLUSIONS

When time is not a barrier, residents are likely to address smoking cessation. Teaching residents how to incorporate this subject into their clinical practice is needed. Raising residents' outcome expectancies may increase their likelihood of addressing smoking cessation.

HIV prevention in primary care: impact of a clinical intervention

Discomfort, lack of confidence in skills, and environmental constraints may cause primary care providers to miss opportunities to discuss human immunodeficiency virus (HIV) risk with patients. We used a systems approach to address both intrapersonal and environmental barriers to HIV risk assessment and prevention counseling in a managed care clinical setting. The design was one-group pretest/posttest. The study took place in two primary care clinics of a large Pacific Northwest managed care organization. Participants (n = 49) included physicians, physician assistants, nurse practitioners, registered nurses, and social workers. The intervention included training, clarification of provider/staff roles, assess to tools and materials, and reminders/reinforcers. Outcome measures were provider attitudes, beliefs, outcome expectations, knowledge, confidence in skills, and perceived supports and barriers, measured by written pretest/posttest surveys administered 12 months apart. Seven months after the most intensive part of the intervention, providers' attitudes and beliefs were more favorable to HIV risk assessment and prevention counseling. They were less likely to express frustration with high-risk patients (decrease from 100% to 79% agreement, p = 0.001) and more confident that their advice would be effective with gay men and single adult heterosexuals (p = 0.002 and 0.005, respectively). They reported more confidence in their training in sexual history taking (p = 0.0003) and their skills assessing readiness for change (p = 0.007), and more support in practice environments. This study demonstrated that it is possible to affect important personal and environmental factors that influence primary care providers' HIV prevention behavior using an interactive, real-world systems approach. Further research is needed on providers' impact on patient behavior.

Cardiovascular disease risk factors among older black, Mexican-American, and white women and men: an analysis of NHANES III, 1988-1994. Third National Health and Nutrition Examination Survey

CONTEXT

There are few studies of ethnic differences in cardiovascular disease (CVD) risk factors in older populations.

OBJECTIVES

To examine the association of ethnicity on CVD risk factors, after accounting for socioeconomic status (SES), and to examine health behaviors among those with CVD risk factors.

DESIGN

Third National Health and Nutrition Examination Survey, 1988-1994.

SETTING

Eighty-nine mobile examination centers.

PARTICIPANTS

700 black, 628 Mexican-American, and 2192 white women and men age 65 to 84 years.

MEASUREMENTS

Ethnicity in relation to type II diabetes mellitus, physical inactivity, abdominal obesity, hypertension, cigarette smoking and non-high-density lipoprotein cholesterol (non-HDL-C).

RESULTS

After accounting for age and SES, both black and Mexican-American women had significantly higher prevalences of type II diabetes than white women. In addition, black women were significantly more likely to have abdominal obesity and hypertension and to be physically inactive than white women. Black men had significantly higher prevalences of hypertension and physical inactivity than white men. However, black men had lower prevalences of abdominal obesity than white men, and black women had lower prevalences of high non-HDL-C than white women. Among those with CVD risk factors, health behaviors were in need of improvement, especially among Mexican-American women whose primary language was Spanish.

CONCLUSIONS

In this national sample of older women and men, black and Mexican American women and black men were at the greatest risk for CVD. These findings parallel the heightened risk of CVD among younger ethnic minority populations and argue for appropriate primary and secondary prevention programs, modified for the language, cultural, and medical needs of older ethnic minorities.

A systems model of clinical preventive care: the case of breast cancer screening among older women. For the NCI Breast Cancer Screening Consortium

BACKGROUND

In older women covered by Medicare, relationships among physician recommendation, mammography in the past 2 years, and clinical breast examination (CBE) in the past year were systematically explored with a variety of predisposing, enabling, and situational factors identified in the Systems Model of Clinical Preventive Care.

METHODS

A population-based survey of women age 65 years and older was conducted in five National Cancer Institute's Breast Cancer Screening Consortium geographic areas. Analyses focused on women with a regular physician and site of care (n = 5318).

RESULTS

Physician recommendation and mammography use declined with women's increasing age and increased with income, education, and insurance. CBE and mammography increased with number of physicians and breast cancer family history; mammography use decreased with worsening health status. Recommendations were higher among physicians who were younger, female, and internists. Family practitioners were older and male; women who saw family practitioners reported characteristics associated with decreased screening-lower income, education, and insurance-and seeing only one physician.

CONCLUSIONS

Public policy and health system changes that create a uniform system of finance and service performance expectations may reduce the persistent discrepancy in physician recommendation and mammography use due to sociodemographics and physician specialty.

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.

Busy physicians and preventive services for adults

OBJECTIVE

To study the relationship between overall productivity and the rates at which primary care physicians, in a fee-for-service setting, deliver or prescribe preventive services to adult patients.

PATIENTS AND METHODS

The charts of 452 adult patients treated by 8 family practitioners and 5 internists in a fee-for-service practice setting were randomly selected and abstracted for provision of 10 preventive services over a 27-month period. The percentage of eligible patients screened for each service was correlated with the production of each physician measured in relative value units (RVUs).

RESULTS

The correlation coefficient between RVUs and the aggregate of the 10 services was 0.23 (95% confidence interval [CI], -0.36 to 0.70). The individual correlation coefficients between RVUs and 9 of the 10 preventive services ranged from -0.05 to 0.43. For cervical cancer screening, however, the correlation coefficient was -0.72 (95% CI, -0.91 to -0.24).

CONCLUSION

With the exception of screening for cervical cancer, the data presented in this study do little to support physicians' common belief that lack of time is the reason they are unable to incorporate prevention strategies into their clinical practice.

Clinical preventive medicine in primary care: background and practice: 1. Rationale and current preventive practices

Impressive evidence supports the value of clinical preventive medicine, defined as the maintenance and promotion of health and the reduction of risk factors that result in injury and disease. Primary prevention activities deter the occurrence of a disease or adverse event, e.g., smoking cessation. Secondary prevention (screening) is early detection of a disease or condition in an asymptomatic stage so treatment delays or blocks occurrence of symptoms, e.g., mammographic detection of breast cancer. Tertiary prevention attempts to not allow adverse consequences of existing clinical disease, e.g., cardiac rehabilitation to prevent the recurrence of a myocardial infarction. Preventive services have decreased morbidity and mortality from both acute and chronic conditions. However, these services are underutilized for numerous reasons. Barriers to their use include physician, patient, and health system factors. The traditional disease/treatment model should be modified to incorporate more preventive services. The subsequent 2 parts of this review will discuss suggestions for integrating primary preventive services and screening into primary care practice.

Undertreatment of hyperlipidemia in the secondary prevention of coronary artery disease

OBJECTIVES

To determine adherence to national guidelines for the secondary prevention of coronary artery disease (CAD) using lipid-lowering drugs (LLDs), by studying the rate of use of LLDs, predictors of use, and the rate of achieving lipid goals, among eligible patients recently hospitalized with acute myocardial infarction.

DESIGN

Cross-sectional analysis of 2,938 medical records, collected from July 1995 to May 1996.

SETTING

Thirty-seven community-based hospitals in Minnesota.

PATIENTS

The 622 patients had previously established CAD and hyperlipidemia (total cholesterol> 200 mg/dL or currently using LLDs), and were eligible for LLDs according to the National Cholesterol Education Program II (NCEP II) Guidelines.

MEASUREMENTS

The use of LLDs in eligible patients (primary outcome) and successful achievement of NCEP II goals (total cholesterol <160 mg/dL) among treated patients (secondary outcome).

MAIN RESULTS

Only 230 (37%) of 622 eligible patients received LLDs. In multivariate logistic regression, factors independently related to LLD use included age greater than 74 years (adjusted odds ratio [AOR] 0.55; 95% confidence interval [CI] 0.35, 0.88) and severe comorbidity (AOR 0.60; 95% CI 0.38, 0.95), managed care enrollee (AOR 1.56; 95% CI 1.02, 2.39), past smoker (AOR 1.72; 95% CI 0.98, 3.01), prior revascularization (AOR 2.31; 95% CI 1.51, 3.53), and the use of aspirin (AOR 1.59; 95% CI 1.07, 2.38) or >/=4 medications (AOR 2.89; 95% CI 2.19, 3.84). Of the treated patients who had lipid levels measured (n = 149), 15% achieved the recommended goal of a total cholesterol below 160 mg/dL. Of the untreated patients (n = 392), 89% were discharged from hospital without a LLD prescription.

CONCLUSIONS

Lipid-lowering drugs, although proven effective for the secondary prevention of CAD, were used by only one third of eligible patients. Among patients receiving LLDs, few achieved recommended lipid goals. Directed quality improvement interventions, such as starting LLDs during hospitalization, may have the potential to substantially reduce CAD morbidity and mortality in this vulnerable population.

Office system interventions supporting primary care-based health behavior change counseling

CONTENT

This article reviews the literature on the effectiveness of office system interventions to improve behavior-change counseling in primary care. These instructions consist of two principle components: tools and teamwork. Tools have been developed to assist providers with health risk assessment (questionnaires, health risk appraisals), prompting and reminding (chart stickers, checklists, flow charts, reminder letters), and education (manuals and handbooks). Teamwork entails the coordination and delegation of tasks between providers and staff.

CONCLUSIONS

A number of clinical trials, particularly in the area of smoking cessation, have demonstrated the effectiveness of tools and teamwork for increasing counseling rates and counseling effectiveness. Although no one type of tool or method of teamwork is consistently more effective than another-with effectiveness varying according to practice, provider, and patient characteristics-the use of different tools and teamwork approaches leads to additive improvements in counseling and patient behavior-change rates. More high-quality research is needed, particularly in the areas of health risk assessment and electronic reminder systems, to develop effective office interventions that can be readily implemented into a wide variety of primary care practices.

Health care providers' perspectives on patient delay for seeking care for symptoms of acute myocardial infarction

To inform intervention development in a multisite randomized community trial, the Rapid Early Action for Coronary Treatment (REACT) project formative research was undertaken for the purpose of investigating the knowledge, beliefs, perceptions, and usual practice of health care professionals. A total of 24 key informant interviews of cardiologists and emergency physicians and 15 focus groups (91 participants) were conducted in five major geographic regions: Northeast, Northwest, Southeast, Southwest, and Midwest. Transcript analyses revealed that clinicians are somewhat unaware of the empirical evidence related to the problem of patient delay, are concerned about the practice constraints they face, and would benefit from concrete suggestions about how to improve patient education and encourage fast action. Findings provide guidance for selection of educational strategies and messages for health providers as well as patients and the public.

Direct observation of exercise counseling in community family practice

BACKGROUND

Although physical activity is important for the prevention and management of a variety of common chronic diseases, the prevalence and patient and visit characteristics associated with provision of physical activity advice by community family physicians is not well understood.

METHODS

In a cross-sectional multi-method study of 138 family physicians in northeast Ohio, exercise advice was measured by direct observation and patient report of consecutive patient visits to 138 practicing family physicians. The association of exercise advice with patient and visit characteristics, assessed by direct observation, medical record review, patient exit questionnaire, and billing data, was determined by logistic regression analysis.

RESULTS

In 4,215 visits by patients older than 2 years of age, exercise counseling was observed during 927 visits (22.3%), but reported by only 13% of patients returning questionnaires. The mean time spent counseling about exercise was 0.78 minutes, with a range of 0.33 to 6.00 minutes (SD = 0.67). Exercise advice was more common during longer visits, visits for well care, and visits by patients who were older, male, and had chronic illnesses for which lack of physical activity is a risk factor.

CONCLUSIONS

Exercise counseling is relatively common during outpatient visits to family physicians, and is more commonly given to patients with risk factors. Multiple patient visits over time present opportunities to integrate exercise counseling among the competing demands of primary care practice.

If diabetes is a public health problem, why not treat it as one? A population-based approach to chronic illness

It is increasingly acknowledged that diabetes and other chronic illnesses are major public health problems. Medicare and many managed health care organizations have recognized the enormous personal and societal costs of uncontrolled diabetes in terms of complications, patient quality of life, and health care system resources. However, the current system of reactive acute-episode focused disease care practiced in many settings does not adequately address this public health problem. An alternative proactive, population-based approach to chronic illnesses such as diabetes is proposed and illustrated. This multilevel systems approach addresses supportive and inhibitory social-environmental factors at multiple levels (personal, family, health care team, work, neighborhood, community). Key disciplines contributing to a population-based approach to diabetes include epidemiology, behavioral science, health care services, public health, health economics, and quality of life professions. Current and potential contributions of each of these disciplines are illustrated and an integrative, population-based systems approach to diabetes management and prevention of complications is proposed. This approach is also seen as applicable to other chronic illnesses.

Promoting tobacco cessation in primary care practice

Promoting tobacco cessation is an important part of the work of clinicians and staff in primary care practice. This article describes the significant public health impact of helping patients quit using tobacco through the use of an effective clinic-based intervention. The most effective strategies are to develop organization commitment, ask every patient about tobacco use at every visit and document it, advise all tobacco users to quit, assess readiness to quit, provide at least brief behavioral counseling, provide follow-up soon after quit date, conduct at least basic evaluations of each component of the process, and assess the quit rate for the practice as a whole.

Diabetes care practices in primary care: results from two samples and three measurement sets

PURPOSE

There has been substantial recent interest in diabetes disease management interventions, guidelines, and care practices. As the vast majority of diabetes care occurs in primary care settings, it makes sense to evaluate current levels of recommended practices in different primary care settings.

METHODS

We report on two separate studies that included a combined total of 389 patients seen by over 30 different providers. Three different sets of recommended practices were assessed: (1) the ADA provider recognition measures, (2) the proposed Diabetes Quality Improvement Project measures, and (3) the state of Oregon Population-Based Guidelines for Diabetes.

RESULTS

In general, there was only a moderate level of adherence to recommended practices, and adherence was much lower for behavioral or patient-focused practices as contrasted with laboratory tests. There was considerable variability across providers and across different guidelines activities.

CONCLUSIONS

Policy and quality improvement implications and future research issues are discussed, including the need for studying different measurement approaches for evaluating guidelines adherence.

Chronic care clinics: a randomized controlled trial of a new model of primary care for frail older adults

OBJECTIVE

To determine whether a new model of primary care, Chronic Care Clinics, can improve outcomes of common geriatric syndromes (urinary incontinence, falls, depressive symptoms, high risk medications, functional impairment) in frail older adults.

DESIGN

Randomized controlled trial with 24 months of follow-up. Physician practices were randomized either to the Chronic Care Clinics intervention or to usual care.

SETTING

Nine primary care physician practices that comprise an ambulatory clinic in a large staff-model HMO in western Washington State.

PARTICIPANTS

Those patients aged 65 and older in each practice with the highest risk for being hospitalized or experiencing functional decline.

INTERVENTION

Intervention practices (5 physicians, 96 patients) held half-day Chronic Care Clinics every 3 to 4 months. These clinics included an extended visit with the physician and nurse dedicated to planning chronic disease management; a pharmacist visit that emphasized reduction of polypharmacy and high-risk medications; and a patient self-management/support group. Control practices (4 physicians, 73 patients) received usual care.

MEASUREMENTS

Changes in self-reported urinary incontinence, frequency of falls, depressive symptoms, physical function, and satisfaction were analyzed using an intention-to-treat analysis adjusted for baseline differences, covariates, and practice-level variation. Prescriptions for high-risk medications and cost/utilization data obtained from administrative data were similarly analyzed.

RESULTS

After 24 months, no significant improvements in frequency of incontinence, proportion with falls, depression scores, physical function scores, or prescriptions for high risk medications were demonstrated. Costs of medical care including frequency of hospitalization, hospital days, emergency and ambulatory visits, and total costs of care were not significantly different between intervention and control groups. A higher proportion of intervention patients rated the overall quality of their medical care as excellent compared with control patients (40.0% vs 25.3%, P = .10).

CONCLUSIONS

Although intervention patients expressed high levels of satisfaction with Chronic Care Clinics, improved outcomes for selected geriatric syndromes were not demonstrated. These findings suggest the need for developing greater system-wide support for managing geriatric syndromes in primary care and illustrate the challenges of conducting practice improvement research in a rapidly changing delivery system.

Implementing nurse-based systems to provide American Indian women with breast and cervical cancer screening

OBJECTIVE

To describe the factors critical to implementation of a nurse-based system to increase access for American Indian women to breast and cervical cancer screening.

MATERIAL AND METHODS

We report the experience of 103 nurses at 40 clinics who were trained to use the nurse-based screening system. In addition, the critical elements are discussed in the context of one particularly successful site.

RESULTS

Fifteen factors were identified as critical to the implementation of a nurse-based cancer screening process once a nurse had been trained to perform clinical breast examinations and collect Papanicolaou (Pap) test specimens: knowledge of benefit, skills, organization, adequate return, perceived patient demand, perceived effectiveness, legitimacy, confidence, commitment, adequate resources, a data-driven iterative approach to program implementation, an objective measure of quality, leadership, the passage of time, and a focus on delivering the service to the patient. For example, in one site that was particularly successful, the nurses, administrators, and other key health-care professionals contributed their respective resources to implement the screening program. The program was also supported by the lay community, the state board of nursing, and the state health department breast and cervical cancer control program. During the 3-year study period, the 103 nurses performed screening tests on 2,483 women, and only 18 of the Pap test specimens were unsatisfactory.

CONCLUSION

Nurse-based systems designed to collect high-quality Pap test specimens and perform detailed clinical breast examinations can be implemented if the factors that are critical to implementation are identified and addressed.

Using an office system intervention to increase breast cancer screening

OBJECTIVE

To evaluate an innovative approach to continuing medical education, an outreach intervention designed to improve performance rates of breast cancer screening through implementation of office systems in community primary care practices.

DESIGN

Randomized, controlled trial with primary care practices assigned to either the intervention group or control group, with the practice as the unit of analysis.

SETTING

Twenty mostly rural counties in North Carolina.

PARTICIPANTS

Physicians and staff of 62 randomly selected family medicine and general internal medicine practices, primarily fee-for-service, half group practices and half solo practitioners.

INTERVENTION

Physician investigators and facilitators met with practice physicians and staff over a period of 12 to 18 months to provide feedback on breast cancer screening performance, and to assist these primary care practices in developing office systems tailored to increase breast cancer screening.

MEASUREMENTS AND MAIN RESULTS

Physician questionnaires were obtained at baseline and follow-up to assess the presence of five indicators of an office system. Three of the five indicators of office systems increased significantly more in intervention practices than in control practices, but the mean number of indicators in intervention practices at followup was only 2.8 out of 5. Cross-sectional reviews of randomly chosen medical records of eligible women patients aged 50 years and over were done at baseline (n = 2,887) and follow-up (n = 2,874) to determine whether clinical breast examinations and mammography, were performed. Results for mammography were recorded in two ways, mention of the test in the visit note and actual report of the test in the medical record. These reviews showed an increase from 39% to 51% in mention of mammography in intervention practices, compared with an increase from 41% to 44% in control practices (p = .01). There was no significant difference, however, between the two groups in change in mammograms reported (intervention group increased from 28% to 32.7%; control group increased from 30.6% to 34.0%, p = .56). There was a nonsignificant trend (p = .06) toward a greater increase in performance of clinical breast examination in intervention versus control practices.

CONCLUSIONS

A moderately intensive outreach intervention to increase rates of breast cancer screening through the development of office systems was modestly successful in increasing indicators of office systems and in documenting mention of mammography, but had little impact on actual performance of breast cancer screening. At follow-up, few practices had a complete office system for breast cancer screening. Outreach approaches to assist primary care practices implement office systems are promising but need further development.

Gender differences in barriers to lifestyle change for cardiovascular disease prevention

Achieving and maintaining a healthy lifestyle are important aspects of a cardiovascular disease prevention program. Few data have evaluated barriers to lifestyle change by gender. We studied self-reported barriers to lifestyle change and evaluated support systems to make positive changes in 293 patients (186 men, 107 women) enrolled in a multidisciplinary preventive cardiology clinic. Subjects were asked to rate barriers and support systems on a scale of 1 to 5, with 1 being very important and 5 not important. Women ranked self-esteem as the most important barrier and rated it significantly higher than did men (p = 0.0003). Women also rated money, knowledge, skills, and stress significantly higher than did men (p < 0.05). Physicians were rated as the most important source of support for both genders. Women, compared with men, rated dietitians, exercise physiologists, nurses, counselors, family members, and social/religious groups as more important sources of support. These data suggest that gender differences exist in barriers to lifestyle change. Psychosocial factors should be considered important elements of programs designed to help patients make positive lifestyle changes.

Activity counseling by primary care physicians

Modifying patients' sedentary lifestyle, a risk factor for many chronic diseases, is a challenge to health professionals. Although physicians can play a vital role in promoting physical activity among sedentary patients, the prevalence of physician-based exercise counseling is low. This paper presents a review of studies that have targeted physicians as agents of behavior change. Changing sedentary behavior is more likely to be effective when the intervention is grounded in theory. This paper outlines an integration of two theoretical models that have potential for enhancing behavior change, and it describes specific techniques for physicians interested in promoting a more active lifestyle among their patients.

Will primary care clinics organize themselves to improve the delivery of preventive services? A randomized controlled trial

BACKGROUND

There is increasing evidence that the most effective way to improve delivery of preventive services in primary care is to establish organized preventive service systems. This study tests the hypothesis that a managed care organization (MCO) can help its contracted private primary care clinics to develop such systems.

METHODS

Forty-four primary care clinics contracting with two large MCOs were randomized to a comparison (C) or an intervention (I) group. Group (I) clinic team leaders received training plus ongoing consultation and networking. Personnel at all 44 clinics completed surveys prior to and at the end of the intervention to measure adoption of the improvement process and the prevention system.

RESULTS

All 22 (I) clinics identified teams that appeared to follow the seven-step improvement process. The mean numbers of system processes were identical at baseline, 11.2 (I) vs 12.1 (C), while after the intervention this had changed to 25.8 in (I) clinics vs 11.3 in (C) (P = 0.022).

CONCLUSIONS

With training and assistance, interested primary care clinic teams will establish functioning CQI teams that will produce a substantial increase in the presence of functional prevention system processes. Whether this change is sufficient to increase the rates of preventive services remains to be documented.

Delivering clinical preventive services is a systems problem

A steadily increasing number of research trials and prevention advocates are identifying the practice environment as the main source of both problems and solutions to the improved delivery of clinical preventive services. Although these sources are correctly focusing on office systems as solutions, there is a tendency to focus on only parts of a system and to relate this to just one or a few related preventive services. However, the effort required to set up and maintain an office system makes it difficult to justify doing so for a single clinical activity. The process and system thinking of Continuous Quality Improvement (CQI) theory suggests that there may be both efficiency and effectiveness advantages to the concept of all clinical preventive services being served by a single system with many interrelated component processes. Such a system should be usable for all age groups. This system and its literature base are described. The feasibility of applying this concept is being tested in a randomized controlled trial in 44 primary care clinics in Minnesota and Wisconsin.

The quality of Pap test specimens collected by nurses in a breast and cervical cancer screening clinic

BACKGROUND

It is possible that nurses can help close the gap between the Healthy People 2000 clinical preventive services goals and current cancer screening rates by collecting Pap test specimens in clinical practices. The purpose of this analysis was to determine whether nurses can collect high-quality Pap tests.

DESIGN

Retrospective cohort analysis of all Pap tests submitted to a commercial pathology laboratory between January 1, 1996 and July 31, 1996. Pap tests collected by the nurses at Rosebud Hospital (N = 404) were compared to the Pap tests collected by other providers at the Rosebud Hospital (N = 118) and the Pap tests collected by providers from all other sites (N = 22,696).

SETTING

The Indian Health Service Hospital, Rosebud, South Dakota.

SUBJECTS

Eight nurses who had been trained to collect Pap test specimens.

MAIN OUTCOME MEASURES

The proportion of Pap test specimens that were wholly satisfactory and the proportion of Pap test specimens collected from nonpregnant patients that lacked endocervical cells.

RESULTS

The proportion of specimens that were wholly satisfactory was 79.8% (95% CI = 75.9-83.7) for the nurses, 65.3% (95% CI = 56.7-73.9) for other Rosebud providers, and 81.7% (95% CI = 81.2-82.2) for non-Rosebud providers. The proportion of specimens that lacked endocervical cells and were from nonpregnant patients was 6.4% (95% CI = 4.0-8.8) for Rosebud nurses, 8.5% for other Rosebud providers (95% CI = 3.5-13.5), and 7.9% for non-Rosebud providers (95% CI = 7.6-8.2).

CONCLUSIONS

After one week of training, nurses can collect Pap test specimens that are of the same quality as the specimens collected by physicians, nurse practitioners, and physician assistants. The widespread availability of female nurses and the high quality of their work suggest that they can contribute to the Healthy People 2000 goals by collecting Pap test specimens.

Family physicians' utilization of a brief smoking cessation program following reinforcement contact after training: a randomized trial

BACKGROUND

Previous studies have examined methods of delivery of brief interventions and reinforcement contact and their effects on physicians' utilization of smoking cessation interventions. In this study the objectives were: (1) to determine the ongoing utilization by family physicians of a brief smoking cessation intervention 6 months after a training workshop and (2) to examine the effect of reinforcement contact on physician utilization. A supplementary aim was to assess point prevalence abstinence among patients identified as ready to quit smoking.

METHODS

This was a randomized controlled trial of family physicians (98 in the Contact and 100 in the Noncontact group). Training was conducted in a 2-hr workshop. Doctors in the Contact group received three brief telephone calls at 2 weeks, 2 months, and 4 months after training. Main outcome measures were: (1) utilization, determined by responses to a mailed questionnaire about use of the program, and (2) the number of booklets distributed by full-time doctors, collected by practice secretaries or research assistant.

RESULTS

At 6 months 88% of physicians (93% of the Contact group and 84% of the Noncontact group, P = 0.06) were current users of the smoking cessation intervention. Full-time physicians in the Contact group distributed significantly more booklets (40.1) over 6 months than those in the Noncontact group (32.8) (P < 0.05). Twenty-one percent of patients reported not smoking at follow-up at an average of 9.9 months after intervention.

CONCLUSIONS

Most doctors continued to use the program 6 months after training and reinforcement contact encouraged greater recruitment of patients.

Using continuous quality improvement to improve diabetes care in populations: the IDEAL model. Improving care for Diabetics through Empowerment Active collaboration and Leadership

BACKGROUND

The care of patients with chronic diseases, especially those with diabetes mellitus, has been less than ideal. However, despite clear national guidelines, various examples of better care models, and multiple attempts to improve care, an effective process for facilitating and replicating diabetes care improvements in typical primary care practices has been elusive.

METHODS

On the basis of the approach and lessons from developmental work at the Minnesota Diabetes Control Program and a trial of continuous quality improvement for clinical preventive services (IMPROVE), a clinic-based intervention processes (IDEAL) has been developed to improve the system and process of care for patients with diabetes as a model for all chronic diseases. The intervention incorporates facilitation of leadership actions in support of change, training for the leader and facilitator of an intraclinic multidisciplinary continuous quality improvement (CQI) team, and consultative and networking support of the change process. Each element of this intervention emphasizes a seven-step process improvement approach and a system for care of patients with diabetes. This model is being developed and tested in a unique partnership between the Minnesota Department of Health and HealthPartners, a large managed care organization (MCO).

RESULTS

A prepilot demonstration has succeeded in improving glycemic control, three primary care clinics affiliated with HealthPartners have succeeded in a pilot of the intervention, and an additional 13 clinics are participating in a randomized controlled trial of a refined intervention.

CONCLUSIONS

The IDEAL model holds promise for substantial improvements in care, not only for diabetes but for all chronic diseases and for other settings.

Redesigning primary care processes to improve the offering of mammography. The use of clinic protocols by nonphysicians

OBJECTIVE

To develop, within the framework of continuous quality improvement, new processes for offering mammography and determine whether protocols executed completely by nonphysicians would increase mammography utilization.

DESIGN

A prospective follow-up study with patients from an intervention clinic and two control clinics.

SETTING

Three general internal medicine clinics in a large, urban teaching hospital in Detroit, Michigan.

PATIENTS/PARTICIPANTS

A total of 5,934 women, aged 40 through 75 years, making 16,546 visits to one of the clinics during the study period (September 1, 1992, through November 31, 1993).

INTERVENTION

Medical assistants and licensed practical nurses in the intervention clinic were trained to identify women due for screening mammography, and to directly offer and order a mammogram if patients agreed.

MEASUREMENTS AND MAIN RESULTS

Patients were considered up-to-date with screening if they had a mammogram within 1 year (if age 50-75) or 2 years (if age 40-49) prior to the visit or a mammogram within 60 days after the visit. The proportion of visits each month in which a woman was up-to-date with mammography was calculated using computerized billing records. Prior to the intervention, the proportion of visits in which women were up-to-date was 68% (95% confidence interval [CI] 63%, 73%) in the intervention clinic and 66% (95% CI 61%, 71%) in each of the control clinics. At the end of the evaluation, there was an absolute increase of 9% (95% CI 2%, 16%) in the intervention clinic, and a difference of 1% (95% CI -5%, 7%) in one of the control clinics and -2% (95% CI -3%, 5%) in the other. In the intervention clinic, the proportion of visits in which women were up-to-date with mammography increased over time and was consistent with a linear trend (p = .004).

CONCLUSIONS

Redesigning clinic processes to make offering of mammography by medical assistants and licensed practical nurses a routine part of the clinic encounter can lead to mammography rates that are superior to those seen in physicians' usual practice, even when screening levels are already fairly high. Physicians need not be considered the sole, or even the primary, member of the health care team who can effectively deliver some preventive health measures.

Delivery rates for preventive services in 44 midwestern clinics

OBJECTIVE

To determine the rates at which private primary-care clinics are recommending blood pressure and cholesterol measurement, smoking cessation, clinical breast examination, screening mammography, Papanicolaou testing, and influenza and pneumococcus immunizations.

MATERIAL AND METHODS

We conducted a mail survey of 7,997 randomly selected patients from 44 primary-care clinics in and around Minneapolis-St. Paul, Minnesota, of whom 6,830 (85.4%) completed the questionnaire on preventive services delivery rates. The responses were analyzed statistically, including stratification by reason for the clinic visit.

RESULTS

On the average, about two-thirds of the patients in each clinic reported being up-to-date on preventive services before their clinic visit; an exception was pneumococcus immunization (mean rate, 33%). Except for blood pressure and smoking cessation advice, less than 30% of patients who were not up-to-date on a preventive service were offered it if the clinic visit was for a reason other than a checkup or physical examination. For patients who said that they saw their physician for a checkup or physical examination, the rate was more than 50% only for Papanicolaou smear. In contrast, nearly all responding practitioners agreed that each of the eight preventive services was very important or important.

CONCLUSION

Preventive services consensus goals are not being met, even for patients who report that their clinic visit was for a checkup or physical examination. This finding suggests that it may be necessary to develop clinical systems that support and enable the delivery of preventive services.

Pediatric injury prevention counseling priorities

OBJECTIVE

Child health care providers have a unique opportunity to conduct injury prevention counseling but limited empirical evidence for choosing prevention strategies. Efficient use of time requires that prevention strategies of higher priority be discussed before lower priority strategies. Our aim was to assess consensus among experts about the prioritization of prevention strategies for office based injury prevention counseling for parents of children under age two.

DESIGN

We used a modified Delphi technique with 23 childhood injury prevention experts nationwide. Participants were blinded to the identities of each other.

MEASURES

The first questionnaire, distributed via facsimile transmission, consisted of open ended questions about prevention strategies participants believe should be included and their prioritization methods. The second questionnaire was closed ended and based on the results of the first.

RESULTS

Seventeen injury problems and 21 prevention strategies were suggested for counseling. Participants emphasized environmental strategies over more active, educational ones. Motor vehicle occupant injuries and car seats were given high priority scores by all participants. Smoke detectors, lowering the hot water heater temperature, and pool fencing also received high priority ratings. Participants based their decisions on the severity of the injury, the frequency with which the injury occured, and the availability of environmental strategies. However, they disagreed about the relative importance of these factors. Time constraints and parents' inability to absorb information led them to suggest limiting, to fewer than four, the number of prevention strategies addressed at any one visit.

CONCLUSIONS

This study illustrates areas of consensus as well as unresolved dilemmas about pediatric injury prevention counseling. A rational decision making approach to prioritizing elements of clinical counseling is needed. Meanwhile, clinicians can use the findings of this study to derive their own judgments.

National Survey on Gender Differences in Cardiac Rehabilitation Programs. Patient characteristics and enrollment patterns

PURPOSE

Cardiac rehabilitation (CR) programs have been shown to promote numerous health benefits among patients with active coronary heart disease (CHD), but little is known about the percentage of eligible CHD patients who enroll in CR.

METHODS

A survey was performed of 500 randomly chosen CR programs in operation in the United States during 1990. Patient characteristics and enrollment data were combined with data from the 1990 National Hospital Discharge Survey to estimate the percentage of eligible patients who participated in early outpatient (Phase II) CR programs after myocardial infarction (MI), after coronary angioplasty (PTCA), or after coronary artery bypass surgery (CABS).

RESULTS

Completed surveys were returned by 163 programs (32.6%) with information on 1,322 women and 1,418 men who enrolled in their programs in 1990. Women were older, more likely to be single, and had more traditional CHD risk factors than men. Only a minority of MI, PTCA, and CABS survivors enrolled in CR programs (10.8%, 10.3% and 23.4%, respectively). Enrollment was particularly low for post-MI and post-CABS women as compared with men: 6.9% versus 13.3% (P < .001), and 20.2% versus 24.6% (P < .001), respectively. Enrollment was generally lowest for nonwhites, those over age 65, and those living in the southern United States.

CONCLUSIONS

Cardiac rehabilitation programs are used by a minority of eligible patients, particularly among women, nonwhites, and the elderly. To meet newly released national guidelines that recommend CR services for most patients recovering from MI, PTCA, or CABS, and to still contain costs, new methods need to be explored that can expand the delivery of CR services in clinical settings.

The promise and performance of HMOs in improving outcomes in older adults

In summary, the promise of HMOs in caring for older adults far exceeds their performance to date. Until recently they had neither the motivation nor the knowledge to revamp their delivery systems to better needs of older, chronically ill patients. Market pressures and skyrocketing costs have provided the motivation. Physicians and researchers trained in epidemiology and health services research from programs such as that at UCLA are providing the knowledge. Based on the literature and experience described above, HMOs with the characteristics supportive of population-based care can put into place an approach to geriatric care likely to improve outcomes if they heed their patients and professionals rather than their accountants. These organizations will give highest priority to preserving function and will be guided by explicit clinical guidelines. Care will be rendered by organized primary care teams supported by systematic self-management approaches, standardized interventions for key risk factors, clinically useful computer systems, and available geriatric expertise. It will require a small revolution as old approaches, roles, and relationships will not go quietly. We are in the early phases of this revolution, and it's not too late to join us on the barricades.
