Hip fracture incidence in nursing home residents and community-dwelling older people, Washington State, 1993-1995.

OBJECTIVES: To establish and validate a method of linking data from the Minimum Data Set (MDS) and Medicare hospital claims, to estimate hip fracture incidence rates for Medicare beneficiaries aged 65 and older in Washington State, and to compare the incidence rates of hip fractures in nursing home and non-nursing home residents. DESIGN: Retrospective analysis of Medicare population-based enrollment, hospital claims, and nursing home administrative data sets. SETTING: Nursing home and non-nursing home setting. PARTICIPANTS: Medicare beneficiaries in Washington State residing in the community or in skilled nursing facilities. MEASUREMENTS: Crude age- and sex-specific and standardized age- and sex-adjusted hip fracture incidence for persons residing and not residing in nursing homes. RESULTS: From October 1, 1993, through September 30, 1995, 7,812 Medicare beneficiaries aged 65 or older were hospitalized for hip fractures (6,566 fractures for 1,155,234 person-years of exposure in non-nursing home residents and 1,246 fractures for 42,986 person-years of exposure in nursing home residents). The standardized age- and sex-adjusted hip fracture rate of nursing home residents (23.0 per 1,000 person-years) substantially exceeded that of non-nursing home residents (5.7 per 1,000 person-years) (incidence rate ratio = 4.0, 95% confidence interval = 3.7-4.5). CONCLUSION: The incidence of hip fracture in nursing home residents far exceeds that in noninstitutionalized older people. Linkage of MDS and Medicare hospital claims data is a useful tool for epidemiological surveillance regarding events in nursing homes that are likely to result in hospitalization.

Perceived risk for developing stroke among older adults.

BACKGROUND: Persons who perceive their risk for stroke accurately may be more likely to engage in prevention practices to reduce their risk. METHODS: In 2004, 800 adults aged 45 years and older in two counties participated in a telephone survey to assess their perceived risk for stroke and their history of stroke risk factors. RESULTS: Overall, 39% of respondents perceived themselves to be at risk for having a stroke. In the multivariate analyses, younger age, current smoking, and a history of diabetes, high blood pressure, high cholesterol, heart disease, and stroke/TIA were independently associated with perceived risk for stroke. Respondents with atrial fibrillation were no more likely to report being at risk for stroke compared to respondents without atrial fibrillation. Perceived risk for stroke increased as the number of risk factors increased. However, 46% of respondents with three or more risk factors did not perceive themselves to be at risk. CONCLUSIONS: Many adults with multiple risk factors do not perceive themselves to be at risk for stroke. Clinical and public health efforts are needed to increase awareness of the risk for stroke.

Accuracy of race coding on American Indian death certificates, Montana 1996-1998.

OBJECTIVES: The purpose of this study was to describe the consistency of coding of American Indians on Montana death certificates and to identify the characteristics of American Indians in Montana associated with consistent classification on death certificates. METHODS: The Billings Area Indian Health Service (IHS) patient registration file was linked with Montana Department of Health and Human Services death certificate files for 1996-1998. RESULTS: A total of 769 Montana residents who had died in 1996-1998 were matched to the IHS registration file. Of these decedents, 696 (91%) were consistently classified as American Indian on the death certificate. Seventy-two (99%) of the 73 decedents not classified as Indian were classified as white. American Indians living in counties on or near the seven Montana reservations were more likely to be consistently classified than Indians living in other counties (95% vs. 70%); those with less than 12 years of education (93% vs. 88%) were more likely to be consistently classified than those with 12 or more years of education. Decedents whose cause of death was suicide were less likely than those with other causes of death to be consistently classified (72% vs. 95%). In contrast, a higher percentage of those with an alcohol-related cause of death than of those with other causes of death were consistently classified, although this difference was not statistically significant. CONCLUSIONS: The mortality rates for Montana American Indians are underestimated overall, and are differentially under- and overestimated for selected conditions.

Smoking cessation and prevention: an urgent public health priority for American Indians in the Northern Plains.

OBJECTIVE: The purpose of this study was to compare the prevalence of cigarette smoking and smoking cessation among American Indians living on or near Montana's seven reservations to those of non-Indians living in the same geographic region. METHODS: Data for Montana Behavioral Risk Factor Surveillance System (BRFSS) respondents (n = 1,722) were compared to data from a BRFSS survey of American Indians living on or near Montana's seven reservations in 1999 (n = 1,000). Respondents were asked about smoking and smoking cessation as well as cardiovascular disease (CVD) and selected risk factors. Quit ratios were calculated for both groups. RESULTS: American Indians were more likely to report current smoking (38%) than non-Indians (19%; p < 0.001). Thirty-seven percent of Indian respondents with CVD risk factors reported current smoking, compared with 17% of non- Indians with CVD risk factors. However, there was no significant difference in reported smoking rates between Indians (21%) and non-Indians (27%) with a history of CVD. Indian smokers were more likely to report quitting for one or more days in the past year (67%), compared with non-Indians (43%). Quit ratios were significantly lower among Indians (43%) than among non-Indians (65%). CONCLUSIONS: High smoking rates in Indians, particularly among those with other CVD risk factors, demonstrate an urgent need for culturally sensitive smoking cessation interventions among Northern Plains Indians and highlight the need for the Surgeon General's focus on smoking in minority populations.

A media campaign to promote pneumococcal vaccinations: is a telephone survey an effective evaluation strategy?

PURPOSE: Media campaigns are used to achieve public health goals but few studies have documented whether the goals were met. METHODS: Two communities received community-wide efforts to increase the pneumococcal polysaccharide vaccine (PPV) rate in defined pneumococcal disease-risk groups. One community also received a media campaign consisting of television and newspaper advertisements. A random-digit-dial telephone survey was conducted before and after the media campaign in both of the designated media markets. In addition to direct mailings to a sample of Medicare beneficiaries whose Medicare billing records did not indicate a PPV billing claim after 1991, community-wide campaigns consisting of table tents, brochures, flyers, and posters occurred in both markets. A 29-day television campaign and a 5-week newspaper campaign occurred in one of the markets. RESULTS: We were unable to detect a significant effect of the media campaign on either PPV awareness or self-reported receipt of pneumococcal vaccine. CONCLUSION: While it is important to evaluate community health intervention efforts, evaluations can be very difficult. Because of financial and other limitations, most feasible evaluation methods will not have the power to detect changes attributable to the intervention nor to provide confidence that there was no important change.

Extending the public health impact of screening for diabetes in high-risk populations: opportunities in American Indian communities.

OBJECTIVE: To assess trends in diabetes screening among American Indian adults and identify opportunities to extend blood glucose screening to those at risk for undiagnosed diabetes and prediabetes. METHODS: In 1999, 2001, and 2003, approximately 1,000 American Indian adults aged 18 years and older living on or near the seven reservations in Montana were interviewed through telephone surveys. RESULTS: Of respondents without diagnosed diabetes, the proportion who recalled blood glucose screening for diabetes within the past 3 years increased from 68 percent in 1999 to 78 percent in 2003. Between 1999 and 2003, screening increased among men (64%-75%), women (71%-80%), those aged 18-44 years (64%-72%), and those aged 45 years and older (76%-84%). Factors independently associated with screening included age more than 45 years, family history of diabetes, and a history of high cholesterol. Current smokers were less likely to report screening compared to nonsmokers. Gender, obesity, and a history of high blood pressure were not associated with screening. CONCLUSIONS: Although self-reported diabetes screening increased over a 5-year period among Indians in Montana, additional groups who could benefit from screening include younger and obese individuals, and those with hypertension.

Do persons with diabetes know their (A1C) number?

PURPOSE: The objective of this study was to compare self-reported knowledge about A1C testing with information from the medical record. METHODS: A telephone survey was conducted among patients with diabetes in a rural fee-for-service practice and a community health center. Self-reported information regarding A1C testing, the last A1C value, and perceived blood glucose control was compared with the most current A1C value documented in the medical record. RESULTS: Seventy five percent of survey respondents reported having 1 or more A1C tests in the past year, which generally agreed with information from their medical records. However, only 24% of those who reported having a test remembered the actual value, and the self-reported values correlated weakly with the last A1C on the medical record. Among those with a documented A1C value, half described their blood glucose as very well controlled. The last A1C value, however, was < 7.0% in only half of those respondents. CONCLUSIONS: Persons with diabetes were aware of their previous A1C testing but did not interpret the values accurately in relation to their own glycemic control. If clinicians expect patient knowledge and understanding of glycemic control measures to improve outcomes of care, patient education will need to emphasize the meaning of these values.

Improving access to quality diabetes education in a rural state: the Montana Quality Diabetes Education Initiative.

PURPOSE: Diabetes self-management education (DSME) is an integral component of diabetes care; however, skilled educators and recognized programs are not uniformly available in rural communities. METHODS: To increase access to quality DSME, the Montana Diabetes Control Program and the Montana chapter of the American Association of Diabetes Educators developed a mentoring program with 3 levels: basic, intermediate, and advanced. All participants were assisted by a volunteer certified diabetes educator (CDE) mentor. In addition, the program provided technical support for recognition through the American Diabetes Association and the Indian Health Service. RESULTS: From 2000 to 2005, 90 individuals participated; 76% were nurses and 21% dietitians. Twenty-seven of the 90 enrollees (30%) completed their structured option, and 13 achieved CDE certification. Most provided services in frontier counties (66%). Statewide, the number of CDEs in Montana increased 46% from 52 in 2000 to 76 in 2005. Twenty-five of the 30 facilities that received technical assistance achieved recognition. Statewide, the number of recognized education programs increased from 2 in 2000 to 22 in 2005. Twelve (55%) of these programs were located in frontier counties. CONCLUSIONS: Mentoring and technical support is an effective method to increase personnel skills for DSME and to increase access to quality education programs in rural areas.

Measuring and improving preventive care for patients with diabetes in primary health centers.

Diabetes care among medically underserved patients is suboptimal. Few studies, however, have described successful strategies to improve diabetes care in these patient populations. To address this issue, 4 Montana community health centers and 1 urban Indian health center implemented quality improvement efforts along with an office-based electronic system for monitoring diabetes care. After a median of 17 months follow-up, preventive services and clinical outcomes were assessed for all patients at baseline (N = 332) and follow-up (N = 590), and for a cohort (N = 164) who had 1 or more visits 6 months after baseline. In cross-sectional analyses, there were increases from baseline to follow-up in the percent of patients who had received an annual foot examination (50% to 68%), microalbuminuria testing (34% to 62%), annual retinal examination (14% to 30%), pneumococcal immunization (30% to 61%), and smoking assessment (77% to 91%). But neither HbA1c testing in the previous 6 months (64% to 55%) nor annual LDL-C testing (59% to 61%) showed any improvement. There were no significant changes from baseline to follow-up in the median hemoglobin A1c (HbAlc), low density lipoprotein-cholesterol (LOL-C), or in systolic and diastolic blood pressure values. Similar improvements in preventive care were seen in the cohort of patients with diabetes. But overall outcomes were not improved. Our findings suggest that office-based monitoring systems can support systems' changes to improve the delivery of preventive services to patients with diabetes in primary care facilities for the underserved, but outcomes are more difficult to enhance over a short period of follow-up. Also, our findings suggest that over a relatively short-term period, cross-sectional and cohort analyses of quality improvement measures do yield similar measures of diabetes care in such settings.
