Racial and socioeconomic disparities in adherence to preventive health services for ovarian cancer survivors.

PURPOSE: To examine ovarian cancer survivors' adherence to evidence-based guidelines for preventive health care. METHODS: A case-control, retrospective study of Medicare fee-for-service beneficiaries diagnosed with stage I, II, or III epithelial ovarian cancer from 2001 to 2010 using the Surveillance, Epidemiology, and End Results-Medicare database. Survivors were matched 1:1 to non-cancer controls from the 5% Medicare Beneficiary file on age, race, state of residence, and follow-up time. Receipt of flu vaccination, mammography, and bone density tests were examined in accordance with national guidelines. Adherence was assessed starting 1 year after cancer diagnosis, across 2 years of claims. Interaction with the health care system, including outpatient and cancer surveillance visits, was tested as a potential mechanism for receipt of services. RESULTS: 2437 survivors met the eligibility criteria (mean age, 75; 90% white). Ovarian cancer survivors were more likely to be adherent to flu vaccination (5 percentage points (pp); < 0.001) and mammography guidelines (10 pp.; < 0.001) compared to non-cancer controls, but no differences were found for bone density test guidelines (- 1 pp.; NS). Black women were less likely to be adherent to flu vaccination and bone density tests compared with white women. Women dually eligible for Medicare and Medicaid were less likely to be adherent compared to those without such support. Adherence was not influenced by measures of outpatient visits. CONCLUSION: Ovarian cancer survivors are receiving preventive services with the same or better adherence than their matched counterparts. Minority and dual-eligible survivors received preventive services at a lower rate than white survivors and those with higher income. The number of outpatient visits was not associated with increased preventive health visits. IMPLICATIONS FOR CANCER SURVIVORS: Ovarian cancer survivors are receiving adequate follow-up care to be adherent to preventive health measures. Efforts to improve care coordination post-treatment may help reduce minority and low SES disparities.

Are Nigerian Women Pro-Active about Noncommunicable Disease Prevention? A Quantitative Survey.

BACKGROUND: Noncommunicable diseases (NCDs) continue to cause significant morbidity and mortality worldwide with incidence increasing rapidly in developing countries. Poor utilization of preventive healthcare services contributes to this high burden. OBJECTIVE: To assess the knowledge and utilization of preventive healthcare services among women in Lagos, Nigeria. METHODS: This was a cross-sectional descriptive study carried out at Mainland Local Government Area (LGA) between May and July 2014. Respondents were selected using the multistage sampling method. A pretested, interviewer-administered questionnaire was used to obtain information. Data were analyzed using Epi info software version 7. Summary and inferential statistics were done and the level of significance was set at <5% (p < 0.05). FINDINGS: Awareness of specified NCDs among the 322 respondents was 82.61% and of preventive healthcare services for the NCDs was 65.22%. Virtually all (99.05%) of the respondents had poor knowledge of these preventive services. Utilization rates were equally poor. Most common screening/tests done were Blood Pressure measurement (78.18%), Self breast examination (69.96%) and blood sugar test (58.33%). Much lower utilization rates were recorded for lipid profile (37.57%), Pap smear (26.11%), Visual Inspection with Acetic Acid (VIA) (19.72%), Human Papilloma Virus (HPV) immunization (16.55%) and mammography (14.72%). CONCLUSIONS: Respondents were aware of specified NCDs and preventive healthcare services. They considered routine medical check-up important, however they had poor knowledge of the preventive health services for NCDs and hardly utilized them. Women should be given detailed information on the preventive healthcare services to improve their knowledge and utilization so as to reduce the NCD burden.

El cuidado de la salud del Ejército de los Andes del general San Martín / The health care of the Army of Andes of General San Martín

A través de la revisión de documentos históricos y otras fuentes bibliográficas, y desde la perspectiva de la enfermería, se describen los recursos y prácticas sanitarias con que contaba el equipo de salud que acompañó al cuerpo del Ejército de los Andes al mando del general José de San Martín desde el inicio del cruce de los Andes el 19 de enero en las Provincias Unidas del Río de la Plata, hasta finalizada la batalla de Chacabuco, en la Capitanía General de Chile, el 12 de febrero de 1817. Este trabajo nos permite conocer el trabajo de los primeros sanitarios militares que asistieron en el cuidado de los soldados de los ejércitos patrios y contribuir así a difundir la historia de la Medicina Argentina.

Acciones motivacionales para promover actividad física en la comunidad que asiste a un Hospital Universitario / Taking action for promoting physical activity in the community attending a university hospital

Introducción: el sedentarismo ha llegado para quedarse. Cualquier tipo de acción para combatirlo será de gran utilidad; solo bastará con conocer su eficacia y con que la gente se adhiera. Métodos: se ha realizado un estudio cuasi experimental antes-después no controlado, con 3 intervenciones aditivas sobre la población que concurre al Hospital Italiano de Buenos Aires (Hospital Universitario). Se comparó la proporción de personas que usaban la escalera mecánica con aquellas que subían por la escalera convencional, antes y después de las siguientes intervenciones: con autoadhesivos que anunciaban las calorías perdidas al subir cada escalón, luego se agregaron carteles acerca del beneficio de hacer actividad física y, por último, se entregaron folletos sobre los beneficios de hacer actividad física. Resultados: se realizaron 39 967 observaciones. Cada intervención significó un aumento de personas que subían por la escalera convencional (P < 0,001). Con la intervención de los autoadhesivos se produjo un incremento del 2,39% frente al basal (11,07% - 8,68%, p=0,001) de personas que subieron por la escalera convencional. La intervención autoadhesivos + cartel aumentó 2,33% (13,4% -11,07%, p=0,001) y la intervención autoadhesivos + cartel + folletos produjo un aumento del 1,09% (14,49%-13,4%, p=0,03). Interpretación: en este estudio se midió cuál era el beneficio de las intervenciones para promover que más gente utilizara la escalera convencional; cada una de ellas proveyó una mayor cantidad de personas que, adoptando una actitud más activa, subieron por la escalera convencional. Medidas sencillas y económicas muestran un gran cambio en promover la actividad física. (AU)

Background: The sedentary lifestyle has become predominant in our society. Any measures taken to fight it are useful, it's just necessary to know their effectiveness and get people to stick with them. Methods: we performed a quasi-experimental pre-post study testing three persistent interventions on the population that attends a university hospital. Its main entrance allows the access to different areas through stairs, escalators or an elevator. We took baseline data on the number of people who took the escalator or the stairs. Then we performed progressive interventions designed to promote the use of the stairs. First, we used stickers placed on in each step that announced the amount of calories burned per step climbed. Then, we placed banners which informed the benefits of physical activity. Lastly, brochures were handed out with a list of benefits of doing physical activity. We quantified the number of people taking the stairs or the escalator with each intervention. Results: in eight weeks 39·967 observations were performed. Each intervention found an increase in the number of people that decided to take the stairs. At baseline, 880 people used the escalator and 9264 people took the stairs. With the first intervention, i.e. the use of stickers on the steps, there was an increase of 2·39% in the number of people that took the stairs compared to baseline data (from 8·68% to 11·07%, p=0.001). With the second intervention, i.e. stickers plus physical activity promotion banners, there was an additional increase of 2·33% (from 11·07% to 13·40%, p=0.001) in the proportion of people taking the stairs. Finally, the intervention of stickers in addition to the banners and brochures about benefits of physical activity, was associated with an increase of 1·09% (from 13·40% to 14·49%, p=0.03). Discussion: in this study we aimed to measure the benefits of multiple interventions to promote physical activity in a university hospital setting. Each intervention was associated with a larger number of people that decided to take the stairs instead of taking the escalator or the elevator. The interventions were simple, cheap and very effective to promote change independently from gender, age or health conditions. (AU)

[Investigation and strategy research of eye disease prevention resources in community health service centers in Shanghai].

OBJECTIVE: To investigate the status of eye disease prevention resources in community health service centers, to understand the distribution of ophthalmology service resources in each community, and to understand the main problems existing in the work of blindness prevention and treatment in Shanghai, so as to strengthen the prevention of blindness and improve the primary eye care level. METHODS: Using the survey method, we carried out the investigation of disease control and prevention resources in all community health service centers to obtain the data of eye disease prevention and treatment resources. Using the descriptive statistics, we described the distribution of resources of eye disease prevention and treatment in different districts. RESULTS: There were 244 communities in 17 districts and counties in Shanghai, of which 236 (96.72%) communities participated in the survey and completed the questionnaires. Forty-nine (20.8%) communities had independent outpatient departments of ophthalmology, 96 (40.7%) had departments of ophthalmology and otorhinolaryngology, 33 (14%) had ophthalmology doctor visits from secondary or tertiary medical institutions, and 87 (36.9%) had no outpatient department of ophthalmology. There were 82 oculists, 129 general or otorhinolaryngology doctors treating eye disease, 9 ophthalmic nurses, and 1 optometrist. There were 36 specialized personnel for public health of eye protection and 217 part-time personnel. Moreover, there were a total of 1 103 pieces of ophthalmic equipment in all communities with the use rate of 91%. CONCLUSIONS: Uneven ophthalmology resources and eye care professional ability in community health service centers, lack of technical and public health personnel for prevention of eye disease, backward eye disease screening equipment, and inadequate investment in prevention and treatment of eye disease are major problems. More government supports for prevention and treatment of eye disease in communities and continuous improvement in three-level blindness prevention network systems and information construction are needed.

The impact of directed choice on the design of preventive healthcare facility network under congestion.

Preventive healthcare (PH) programs and services aim at reducing the likelihood and severity of potentially life-threatening illness by early detection and prevention. The effectiveness of these programs depends on the participation level and the accessibility of the users to the facilities providing the services. Factors that impact the accessibility include the number, type, and location of the facilities as well as the assignment of the clients to these facilities. In this paper, we study the impact of system-optimal (i.e., directed) choice on the design of the preventive healthcare facility network under congestion. We present a model that simultaneously determines the location and the size of the facilities as well as the allocation of clients to these facilities so as to minimize the weighted sum of the total travel time and the congestion associated with waiting and service delay at the facilities. The problem is set up as a network of spatially distributed M/G/1 queues and formulated as a nonlinear mixed integer program. Using simple transformation of the nonlinear objective function and piecewise linear approximation, we reformulate the problem as a linear model. We present a cutting plane algorithm based exact (𝜖-optimal) solution approach. We analyze the tradeoff between travel time and queuing time and its impact on the location and capacity of the facilities as well as the allocation of clients to these facilities under a directed choice policy. We present a case study that deals with locating mammography clinics in Montreal, Canada. The results show that incorporating congestion in the PH facility network design substantially reduces the total time spent by clients. The proposed model allows policy makers to direct clients to facilities in an equitable manner resulting in better accessibility.

CONCLUSIONES: La Evaluación Rápida de Ceguera Evitable es una metodología sólida, sencilla y económica para determinar la prevalencia de ceguera y deficiencia visual y la cobertura y calidad de los servicios de salud ocular, y representa una herramienta muy valiosa para medir el progreso de los programas de prevención de la ceguera y su impacto en la población.

OBJECTIVE: Describe the rationale and methodology of the Rapid Assessment of Avoidable Blindness applied in surveys at the national level in 2011-2013 in Argentina, El Salvador, Honduras, Panama, Peru, and Uruguay. METHODS: The survey includes individuals aged 50 years and older, minimizing required sample sizes, which vary from 2 000 to 5 000 people. It uses straightforward sampling and examination techniques, and data analysis is automatic and does not require a statistician. It is relatively inexpensive, as it does not take a long time, does not require expensive ophthalmic equipment, and can be carried out by local staff. Reports are generated by the assessment software package. RESULTS: Indicators measured are prevalence of blindness and of moderate and severe visual impairment (broken down into avoidable causes and cataracts); prevalence of aphakia or pseudophakia; cataract surgical coverage; visual outcome of cataract surgeries; causes of poor outcomes; access barriers to cataract surgery; and cataract surgery service indicators. Results of each survey will be published sequentially in successive issues of the Journal, and a final summary article will analyze results as a whole and in comparison with the other surveys in this group and with those previously published, which will provide a current picture of the situation in this group of countries. CONCLUSIONS: The Rapid Assessment of Avoidable Blindness is a robust, simple, and inexpensive methodology to determine prevalence of blindness and visual impairment as well as eye health service coverage and quality. It is a very valuable tool for measuring progress by blindness prevention programs and their impact on the population.

Characteristics of U.S. emergency departments that offer routine human immunodeficiency virus screening.

OBJECTIVES: The association between emergency department (ED) characteristics, ED director's perceptions of preventive services, and the availability of human immunodeficiency virus (HIV) screening are unknown. The authors hypothesized that, after adjusting for ED operational and demographic characteristics, teaching hospital status would be associated with increased availability, and ED crowding and ED director agreement with barriers to screening would be associated with decreased availability. METHODS: This was a secondary, cross-sectional analysis on previously collected data from 2008 to 2009 regarding availability of ED preventive services. Data were obtained from a random sample of 277 EDs in which ED directors provided information on ED characteristics and availability of HIV screening and rated five barriers to providing preventive services. The association between the availability of HIV screening and teaching hospital and crowding status, ED volume, urban-rural location, ownership, geographic region, patient demographics, state HIV testing consent laws, and ED director opinions on barriers to providing preventive services were determined in univariate analyses and a multivariate logistic regression model. RESULTS: Nineteen percent of the sampled EDs offer HIV screening. Teaching hospitals offer HIV screening more frequently than nonteaching hospitals (38% vs. 18%; p = 0.03), but after adjusting for other characteristics in a multivariate model, this association was not significant (relative risk ratio [RR] = 2.07, 95% confidence interval [CI] = 0.91 to 3.59). ED crowding also was not significantly associated with screening availability (RR = 0.66, 95% CI = 0.34 to 1.21). However, public ownership (RR = 2.13, 95% CI = 1.28 to 3.14), 24-hour social work (RR = 1.87, 95% CI = 1.02 to 2.99), uninsured population ≥35% (RR = 2.48, 95% CI = 1.39 to 3.69), increased local nonwhite minority population percentage (RR = 1.14 per 10%, 95% CI = 1.02 to 1.26), and state laws allowing opt-out consent for testing (RR = 1.76, 95% CI = 1.01 to 2.74) were associated with increased availability of screening in multivariable analysis. EDs whose directors were concerned about added costs were associated with decreased availability of screening (RR = 0.45, 95% CI = 0.23 to 0.85). CONCLUSIONS: After adjusting for other ED operational and demographic characteristics, ED crowding and teaching hospital affiliation were not independently associated with the availability of HIV screening. EDs whose directors were concerned about the cost of preventive services were less likely to provide routine HIV screening. Addressing ED director's concerns about the added costs of ED preventive services, increasing social work availability, and implementing testing laws consistent with Centers for Disease Control and Prevention (CDC) recommendations may facilitate increased adoption of ED HIV screening.

Cobertura de programas preventivos en Chile / Coverage with preventive programs in Chile

Introducción: Los Programas de Medicina Preventiva para que tengan un impacto en el nivel de salud deben tener una alta cobertura poblacional. Objetivo: Estudiar la cobertura de los programas preventivos que se realizaron en el Sistema de Salud Público Chileno el año 2007. Material y Métodos: Se revisó la cobertura de los programas preventivos en las bases de datos del Departamento de Estadísticas e Información en Salud del Ministerio de Salud de Chile del año 2007. Resultados: La cobertura global de los programas preventivos medido a través del Índice de Medicina Preventiva fue de0.202. El programa de salud dirigido a los < de 6 años (infantil) fue el que registró una mayor cobertura (0.84), un nivel de cobertura intermedio se observó en los programas de la mujer (0.34) y del adulto mayor (0.29), por su parte los programas dirigidos a la población escolar, adolescente y adulto fueron los que presentaron menores coberturas (<0.1). Discusión: La alta cobertura observada en el programa preventivo dirigido a la población infantil, ha sido un factor que ha favorecido la mejoría en el nivel de salud de este grupo poblacional, particularmente ha contribuido a reducirla mortalidad infantil en Chile. El país debe crear estrategias que permitan incrementar la cobertura en programas preventivos dirigidos a la población escolar, adolescente y adulta, solo de esta forma podrá seguir avanzando en la senda de mejorar el nivel de salud poblacional.

Introduction: In order to have an impact on the level of health, Preventive Medicine Programs should have high population coverage. Objective: To study the coverage of preventive programs which were conducted in the Chilean Public Health System in 2007. Material and Methods: The coverage of preventive programs in the databases of the Department of Health Statistics and Information of the Chilean Ministry of Health in the year 2007 were reviewed. Results: The overall coverage of preventive programs as measured by the index of Preventive Medicine was 0.202. The health program aimed at < 6 years (children) was the one that recorded a greatest coverage (0.84). An intermediate level of coverage was observed in the women’s program (0.34) and in that of elderly (0.29). Programs conducted for school children, teenagers, and adults presented a low coverage (<0.1). Discussion: The high coverage observed in the child health preventive program, has been a factor that has led to the improvement of the health status of this population group. Particularly, it has contributed to reduce the infant mortality in Chile. The country must create strategies to increase the coverage of preventive programs aimed at schoolchildren, teenagers and adults. Only in this way we can go on improving the level of population health.

National survey of preventive health services in US emergency departments.

STUDY OBJECTIVE: We describe the availability of preventive health services in US emergency departments (EDs), as well as ED directors' preferred service and perceptions of barriers to offering preventive services. METHODS: Using the 2007 National Emergency Department Inventory (NEDI)-USA, we randomly sampled 350 (7%) of 4,874 EDs. We surveyed directors of these EDs to determine the availability of (1) screening and referral programs for alcohol, tobacco, geriatric falls, intimate partner violence, HIV, diabetes, and hypertension; (2) vaccination programs for influenza and pneumococcus; and (3) linkage programs to primary care and health insurance. ED directors were asked to select the service they would most like to implement and to rate 5 potential barriers to offering preventive services. RESULTS: Two hundred seventy-seven EDs (80%) responded across 46 states. Availability of services ranged from 66% for intimate partner violence screening to 19% for HIV screening. ED directors wanted to implement primary care linkage most (17%) and HIV screening least (2%). ED directors "agreed/strongly agreed" that the following are barriers to ED preventive care: cost (74%), increased patient length of stay (64%), lack of follow-up (60%), resource shifting leading to worse patient outcomes (53%), and philosophical opposition (27%). CONCLUSION: Most US EDs offer preventive services, but availability and ED director preference for type of service vary greatly. The majority of EDs do not routinely offer Centers for Disease Control and Prevention-recommended HIV screening. Most ED directors are not philosophically opposed to offering preventive services but are concerned with added costs, effects on ED operations, and potential lack of follow-up.

Applying the small-area estimation method to estimate a population eligible for breast cancer detection services.

INTRODUCTION: Populations eligible for public health programs are often narrowly defined and, therefore, difficult to describe quantitatively, particularly at the local level, because of lack of data. This information, however, is vital for program planning and evaluation. We demonstrate the application of a statistical method using multiple sources of data to generate county estimates of women eligible for free breast cancer screening and diagnostic services through California's Cancer Detection Programs: Every Woman Counts. METHODS: We used the small-area estimation method to determine the proportion of eligible women by county and racial/ethnic group. To do so, we included individual and community data in a generalized, linear, mixed-effect model. RESULTS: Our method yielded widely varied estimated proportions of service-eligible women at the county level. In all counties, the estimated proportion of eligible women was higher for Hispanics than for whites, blacks, Asian/Pacific Islanders, or American Indian/Alaska Natives. Across counties, the estimated proportions of eligible Hispanic women varied more than did those of women of other races. CONCLUSION: The small-area estimation method is a powerful tool for approximating narrowly defined eligible or target populations that are not represented fully in any one data source. The variability and reliability of the estimates are measurable and meaningful. Public health programs can use this method to estimate the size of local populations eligible for, or in need of, preventive health services and interventions.

[Coverage of preventive health activities in a Chilean region, calculated using the preventive medicine index]. / Indice de medicina preventiva: Una medida integradora de la cobertura de los programas preventivos.

BACKGROUND: Preventive activities of the public health system in Chile are not integrated and there is no parameter assessing the whole population that is benefited with these activities. AIM: To develop and implement a mathematical measure of the coverage of preventive health activities, provided to different age groups. MATERIAL AND METHODS: Data was gathered from the monthly statistical reports of the women, children, teenager, adult and elderly health programs in 30 communities of the Seventh Chilean Region. The preventive medicine index (PMI) was calculated as the ratio between the population that was ascribed to each program and the population that was a potential beneficiary of such program. RESULTS: In the studied region, the global coverage of preventive medicine, calculated using the PMI, increased from 0.229 in 1999 to 0.370 in 2003. This represents a 61% increment. However, there are important inequalities in the access to preventive health in the different communities of the region. CONCLUSIONS: The PMI revealed a substantial increment in preventive health activities in the studied region.

Improving the delivery of preventive care services.

Performance of preventive services is an important indicator of high-quality health care, but many recommended services are not regularly offered in primary care practices. Health risk assessments, counseling, and referral to community-based programs help address risk behaviors, many of which are leading causes of preventable death and disability in the United States. This study examined various influences on the delivery of preventive services designed to address smoking, excessive consumption of alcohol, unhealthy diets, and sedentary lifestyles. More than 300 health care providers in 52 practices nationwide have contributed data to this study. Staff participation in quality improvement enhanced work relationships and also diminished the effect of practice size on the performance of preventive care. The use of nurse practitioners, allied health professionals, clinician reminders, and patient registries were positively associated with care delivery.

Disease prevalence and use of preventive services: comparison of female veterans in general and those with spinal cord injuries and disorders.

BACKGROUND: Disease prevalence and use of preventive services may differ between women veterans in general and those with spinal cord injuries and disorders (SCI&D). Prevention is particularly important in SCI&D, and disparities may exist in receipt of this care, particularly when special equipment and body adjustments are needed, among women with SCI&D. METHODS: To compare disease prevalence and preventive service use among female veterans in general and those with SCI&D, we conducted a cross-sectional survey among female veterans in general (n = 478) and those with SCI&D (n = 115). Behavioral Risk Factor Surveillance System (BRFSS) survey questions were administered to veterans with SCI&D and compared with 2003 CDC BRFSS data. RESULTS: Female veterans with SCI&D were similar in age and race but were better educated and less likely to be employed than female veterans in general. Coronary heart disease (CHD) prevalence was higher in those with SCI&D (17% vs. 8%, p < 0.0001). Health status was lower in SCI&D (27%) than in general female veterans (41%), p = 0.002. Fewer women with SCI&D, than female veterans in general reported having received recommended dental care (56% vs. 69%, p = 0.004), colon screening in prior 5 years (59% vs. 72%, p = 0.023) or prior 10 years (67% vs. 92%, p< 0.0001), mammogram (84% vs. 91%, p = 0.019), and Pap smear (88% vs. 98%, p < 0.0001). There were no differences in receipt of respiratory vaccinations or cholesterol screening. CONCLUSIONS: Receipt of services that require the use of equipment, body adjustments, and potential discomfort due to disability was lower in women with SCI&D. Veterans Affairs (VA) is doing well in most areas, but there are gaps in receipt of some preventive services. Efforts to increase preventive care in women with SCI&D should address equipment and access barriers and patient and provider education.

Effects of sex, age, and visits on receipt of preventive healthcare services: a secondary analysis of national data.

BACKGROUND: Sex and age may exert a combined influence on receipt of preventive services with differences due to number of ambulatory care visits. METHODS: We used nationally representative data to determine weighted percentages and adjusted odds ratios of men and women stratified by age group who received selected preventive services. The presence of interaction between sex and age group was tested using adjusted models and retested after adding number of visits. RESULTS: Men were less likely than women to have received blood pressure screening (aOR 0.44;0.40-0.50), cholesterol screening (aOR 0.72;0.65-0.79), tobacco cessation counseling (aOR 0.66;0.55-0.78), and checkups (aOR 0.53;0.49-0.57). In younger age groups, men were particularly less likely than women to have received these services. In adjusted models, this observed interaction between sex and age group persisted only for blood pressure measurement (p = .016) and routine checkups (p < .001). When adjusting for number of visits, the interaction of age on receipt of blood pressure checks was mitigated but men were still overall less likely to receive the service. CONCLUSION: Men are significantly less likely than women to receive certain preventive services, and younger men even more so. Some of this discrepancy is secondary to a difference in number of ambulatory care visits.

Delivery of preventive services to older adults by primary care physicians.

CONTEXT: Rates of preventive services remain below national goals. OBJECTIVE: To identify characteristics of physicians and their practices that are associated with the quality of preventive care their patients receive. DESIGN: Cross-sectional analysis of data on US physician respondents to the 2000-2001 Community Tracking Study Physician Survey linked to claims data on Medicare beneficiaries they treated in 2001. Physician variables included training and qualifications and sex. Practice setting variables included practice type, size, sources of revenue, and access to information technology. Analyses were adjusted for patient demographics and comorbidity, as well as community characteristics. SETTING AND PARTICIPANTS: Primary care delivered by 3660 physicians providing usual care to 24 581 Medicare beneficiaries aged 65 years and older. MAIN OUTCOME MEASURES: Proportion of eligible beneficiaries receiving each of 6 preventive services: diabetic monitoring with hemoglobin A(1c) measurement or eye examinations, screening for colon or breast cancer, and vaccination for influenza or pneumococcus in 2001. RESULTS: Overall, the proportion of beneficiaries receiving services was below national goals. Physician and, more consistently, practice-level characteristics were both associated with differences in the delivery of services. The strongest associations were with practice type and the percentage of practice revenue derived from Medicaid. For instance, beneficiaries receiving usual care in practices with less than 6% of revenue from Medicaid were more likely than those with more than 15% of revenue derived from Medicaid to receive diabetic eye examinations (48.9% vs 43%; P = .02), hemoglobin A1c monitoring (61.2% vs 48.4%; P<.001), mammograms (52.1% vs 38.9%; P<.001), colon cancer screening (10.0% vs 8.5%; P = .60), and influenza (50.2% vs 39.2%; P<.001) and pneumococcal (8.2% vs 6.4%; P<.001) vaccinations. Other variables associated with delivery of preventive services after adjustment for patient and geographic factors included obtaining usual health care from a physician who worked in group practices of 3 or more, who was a graduate of a US or Canadian medical school, or who reported availability of information technology to generate preventive care reminders or access treatment guidelines. CONCLUSIONS: Delivery of routine preventive services is suboptimal for Medicare beneficiaries. However, patients treated within particular practice settings and by particular subgroups of physicians are at particular risk of low-quality care. Profiling these practices may help develop tailored interventions that can be directed to sites where the opportunities for quality improvement are greatest.
