Foot care practices, services and perceptions of risk among medicare beneficiaries with diabetes at high and low risk for future foot complications.

A cohort of Medicare beneficiaries with diabetes was identified from inpatient and outpatient claims data and their risk for foot complications was estimated based on claims reflecting services for recent foot problems. A telephone survey of a random sample from this cohort was conducted to assess their foot care practices, barriers, and perceptions of risk. Eight percent of respondents reported a history of foot ulcers and 7% a history of lower extremity amputation. Based on claims data, 30% of respondents were at high risk for future foot complications. Compared to those at low risk, those at high risk were more likely to report having an annual foot exam, using protective footwear, and perceiving themselves to be high risk for future foot complications. However, 50% of those with claims indicating a high risk perceived themselves to be at low risk for future foot complications. Overall, 20% of respondents seldom checked their feet daily for sores or irritations. Among this group, 60% felt that it was unimportant and 9% reported they were limited by poor vision or physical problems. Our findings suggest that strategies are needed to improve the delivery of preventive foot care services to older persons with diabetes. Additionally, emphasis is needed to help individuals understand their risk and seek and perform appropriate preventive foot care.

Improving glycemic control: can techniques used in a managed care setting be successfully adapted to a rural fee-for-service practice?

The objective of this work was to improve glycemic control using case management supported by electronic diabetes care monitoring. Information for patients with diagnosed diabetes in a rural community was maintained in the Diabetes Care Monitoring System. In September 1998, counseling and medication management for glycemic control was intensified during individual office visits. And, from September 1998 to February 1999, 2-hour cluster visits modeled after a successful urban program were offered for groups of patients with elevated HbA1c values. The median (and 75th percentile) HbA1c values for the patient population decreased from 8.7% (10.9%) in March 1998 (N = 173) to 7.5% (9.3%) in March 1999 (N = 182) and was maintained at 7.5% (9.1%) through March 2000 (N = 182). Case management, including cluster visits, can be accomplished in a rural physician's office with the support of an electronic diabetes care monitoring system. This intensified approach decreased and sustained the HbA1c level by more than a percentage point for the patient population.

Establishing surveillance for diabetes in American Indian youth.

OBJECTIVE: To determine prevalence estimates in order to monitor diabetes, particularly type 2 diabetes, in American Indian youth. RESEARCH DESIGN AND METHODS: To explore the feasibility of developing a case definition using information from primary care records, all youth aged <20 years with an outpatient visit or hospitalization for diabetes were identified from the Billings Area Indian Health Service database in Montana and Wyoming from 1997 to 1999, and the medical records were reviewed. Classification for probable type 1 diabetes was based on age < or =5 years, weight per age < or =15th percentile at diagnosis, or positive results of islet cell antibody test. Classification for probable type 2 diabetes was based on weight per age > or =85th percentile or presence of acanthosis nigricans at diagnosis, elevated C-peptide or insulin, family history for type 2 diabetes, or use of oral hypoglycemic agents with or without insulin or absence of current treatment 1 year after diagnosis. RESULTS: A total of 52 case subjects with diabetes were identified, 3 of whom had diabetes secondary to other conditions. Of the remaining 49 case subjects, 25 (51%) were categorized as having probable type 2 diabetes, 14 (29%) as having probable type 1 diabetes, and 10 (20%) could not be categorized because of missing or negative information. Prevalence estimates for diabetes of all types, type 1 diabetes, and type 2 diabetes were 2.3, 0.6, and 1.1, respectively, per 1,000 youth aged <20 years. CONCLUSIONS: Our definitions may be useful for surveillance in primary care settings until further studies develop feasible case definitions for monitoring trends in diabetes among youth.

Cardiovascular disease and risk factors in Montana American Indians and non-Indians.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death for both American Indian and non-Indian adults. Few published studies have compared the prevalence of CVD and related risk factors in Indians to that in non-Indians in the same geographic area. OBJECTIVE: To compare CVD and risk factors in American Indian and non-Indian populations in Montana. METHODS: Adult American Indians (n=1000) living on or near Montana's seven reservations and non-Indian (n=905) Montanans statewide were interviewed through the 1999 Behavioral Risk Factor Surveillance Survey (BRFSS). RESULTS: Indians aged > or =45 years reported a significantly higher prevalence of CVD compared to non-Indians (18% vs 10%). In persons aged 18-44 years, Indians were more likely to report hypertension (15% vs 10%), obesity (29% vs 12%), and smoking (42% vs 24%) compared to non-Indians. For persons aged > or =45 years, Indians reported higher rates of diabetes (24% vs 9%), obesity (38% vs 16%), and smoking (32% vs 13%) compared to non-Indians. Non-Indians aged > or =45 years reported having been diagnosed with high cholesterol more frequently than did Indians (32% vs 24%). CONCLUSIONS: Both Indians and non-Indians in Montana reported a substantial burden of CVD. The CVD risk patterns differ in the two populations. Prevention programs should be tailored to the risk burdens in these communities with particular emphasis on smoking cessation and the prevention of obesity.

Comparing self-reported measures of diabetes care with similar measures from a chart audit in a well-defined population.

The objective of this study was to compare self-reported measures of diabetes care with measures derived from medical records in a well-defined population. Diabetes measures were collected through a 1997 Behavioral Risk Factor Surveillance System telephone survey of American Indians living on or near 7 Montana reservations (N = 398) and were compared with data collected from charts of a systematic sample of American Indians with diabetes seen in 1997 at Indian Health Service (IHS) facilities. Survey respondents were more likely to report a duration of diabetes > or = 10 years (44 vs 31%), annual dilated retinal exam (75 vs 59%), and an influenza immunization in the past year (73 vs 57%) compared with estimates from the chart audit. Estimates of pneumococcal immunization (88 vs 42%), annual cholesterol screening (86 vs 69%), and overweight, based on body mass index (67 vs 50%), were significantly higher from the chart audit. No significant differences were found between the survey respondents and the chart audit data for annual foot exams (65 vs 61%), annual blood pressure checks (98 vs 93%), high cholesterol (35 vs 41%), and high blood pressure (54 vs 64%). These findings suggest that self-reported data may over and underestimate specific measures of diabetes care.

Direct mail intervention to increase retinal examination rates in Medicare beneficiaries with diabetes.

The objective of this study was to identify the baseline frequency of eye examinations for Medicare beneficiaries with diabetes in Montana and to determine whether a direct mail reminder increased eye examinations. Using Medicare Part A and Medicare Part B claims data, a cohort of Medicare beneficiaries with diabetes was defined. Eye examination claims were identified using billing codes specific for retinal examinations, as well as visits to ophthalmologists and optometrists during which retinal exams were likely to have been performed. A random sample of the identified beneficiaries with diabetes received a letter encouraging regular annual retinal examinations. In the first 3-month period after the mailing, the billed eye examination rate for those to whom letters were sent was 2.2 percentage points greater than the rate for those to whom letters were not sent (19.4% vs 17.2%; relative risk, 1.13; 95% confidence interval, 1.01-1.26). However, 6 months after the letters were sent, there was no longer a significant difference in the rates for these 2 groups (32.9% vs 32.4%; relative risk, 1.02; 95% confidence interval, 0.94-1.10). In this study, direct mail outreach initially influenced the proportion of Medicare beneficiaries receiving an eye examination, but this pattern was not sustained over the 6-month follow-up period.

Population surveillance for physical violence among adult men and women, Montana 1998.

BACKGROUND: Few epidemiologic studies of physical violence or intimate partner violence provide population-based surveillance data. OBJECTIVES: To estimate the prevalence and describe the characteristics associated with physical violence among adult men and women in the past year. METHODS: A random sample of Montana households was contacted via the Behavioral Risk Factor Surveillance System telephone survey in 1998 (N=1804). RESULTS: Five percent of men (39/787) and 3% of women (33/1017) reported experiencing physical violence in the past year. Among respondents reporting physical violence in the past year, women were more likely than men to report that the perpetrator was a current/former partner (58% vs 10%, p/=0.05). Men who reported experiencing physical violence in the past year were more likely to be younger and not to be living with a current partner. Women who reported experiencing physical violence in the past year were more likely to be younger, not currently living with a partner, have no health insurance, and have more days with mental health problems in the past month. CONCLUSIONS: Recent physical violence is common for both men and women; however, the perpetrators, locations, and demographic characteristics differ. Further study is needed to better understand the factors associated with physical violence among men and women in the context of designing and implementing appropriate interventions to reduce violence.

Sexual activity, substance use, and HIV/STD knowledge among detained male adolescents with multiple versus first admissions.

BACKGROUND: Incarcerated and detained youth are at high risk for sexually transmitted diseases (STD), including human immunodeficiency virus (HIV). GOAL OF THE STUDY: To compare the level of sexual activity and substance use-related risk and knowledge regarding HIV/STD among male adolescents with multiple (YMA) versus first admissions (YFA) to a detention facility as a basis for the development of specific intervention strategies. STUDY DESIGN: Sexual and substance use histories, HIV/STD knowledge, and perceived risk were collected through structured interviews of a consecutive sample of detained youth. Human immunodeficiency virus antibody seroprevalence was determined using a blind study of discarded blood. RESULTS: Overall, these youth (N = 486) reported high levels of noninjection drug use, sexual risk activities, and knowledge regarding HIV/STD prevention. Furthermore, most of these youth reported that their risk for HIV infection was low (68%). Eighty-one percent of all youth reported recent (past 6 months) vaginal sex, and 14% reported insertive anal sex. Controlling for age, YMA were more likely to initiate sex at age 13 or younger (OR 1.38; 95% CI, 1.11-1.70), to report eight or more lifetime sex partners (OR 1.36; 95% CI, 1.13-1.63), and to have ever exchanged drugs or money for sex (OR 1.54; 95% CI, 1.08-2.19). However, these youth were less likely to report condom use with their last sex partner (OR 0.74; 95% CI, 0.60-0.93). More than one third (34%) of all youth felt that consistent use of condoms would not provide a high level of protection against HIV. CONCLUSION: Youth with multiple versus first admissions are at higher risk of HIV/STD infections through their lifetime and recent sexual activities. Interventions targeted to this population will need to address the barriers to and facilitators of condom use, strategies to promote positive attitudes toward condoms, and strategies to reduce the high level of alcohol and substance use.

Results of a domestic violence training program offered to the staff of urban community health centers. Evaluation Committee of the Philadelphia Family Violence Working Group.

INTRODUCTION: Domestic violence (DV) against women often goes unrecognized by health care providers due to multiple barriers. In an effort to increase screening, identification, and referral for services, the RADAR Training Project was created for the health care staff of 12 federally qualified community health centers (CHCs). METHODS: A two-phase evaluation was conducted to assess the intervention. Phase one evaluated the health care providers' perceived knowledge and comfort pre-training, post-training, and at 3 months follow-up. The second phase included a medical chart review of 4 CHCs to assess the rates of screening, documentation of abuse, assessment of safety, and referrals for help at baseline (6 months pre-training) as compared to the intervention period (6 months post-training). RESULTS: The health care providers' perceived level of knowledge and comfort increased significantly post-training and then later decreased at 3 months follow-up. The rate of screening for DV (25% vs. 5%), suspicion of DV (6% vs. 2%), completion of safety assessments (17% vs. 5%), and referrals (4% vs. 0%) increased significantly between the intervention and baseline periods. However, the rates of documentation of abuse did not change. CONCLUSIONS: This intervention was successful in increasing provider perceived knowledge and comfort; however, comfort decreased at follow-up. Additionally, the rates of screening and referrals increased 6 months post-training. Health care provider training and support and integrated quality assurance mechanisms may be necessary to increase the overall rate of these activities, and to sustain this effort over time. Further study is needed to identify effective methods to increase provider comfort regarding DV screening.

Pediatric primary care provider's knowledge of HIV/AIDS care.

To respond to the difficulties that community-based providers face in keeping abreast of the rapid changes in HIV-related care, an intensive pediatric HIV mentoring program (Pediatric HIV Miniresidency [MR]) was developed, linking a regional AIDS Education and Training Center (AETC) with an urban children's hospital HIV outpatient care site. The purpose of this study was to evaluate HIV-related knowledge and perceived skills, abilities, and willingness of community-based primary care pediatric providers and providers completing the MR. A convenience sample of community-based primary pediatric practitioners and those participants in the MR program completed a three-part mailed survey. The survey assessed practice characteristics, knowledge of pediatric HIV clinical care, and perceived skills, ability, and willingness (PSAW) to provide HIV-related care. The main outcome measures were overall knowledge and PSAW scores. One hundred nineteen community-based practitioners (NMRs), 20% of those surveyed, completed the instrument, as did 19 of 20 MR participants. NMRs exhibited low knowledge scores in key areas relating to the identification and evaluation of HIV-exposed children. Fewer than half of these respondents correctly answered questions related to HIV antibody incidence in HIV-exposed newborns and recommended diagnostic testing of such infants. Providers completing the MR scored significantly higher on the knowledge survey (15.2 vs. 8.8, p < 0.001), and had higher PSAW scores (45.8 vs. 33.9, p < 0.001). Although the generalizability of our study is limited by the low response rate, community-based physicians completing the survey demonstrated a lack of knowledge we believe necessary to provide pediatric HIV-related care (as defined by Public Health Service practice guidelines). Physicians completing the MR program had substantial HIV-related knowledge and expressed a willingness to provide care to HIV-exposed/infected children. An effective MR program provides a mechanism for developing a network of dedicated community-based physicians who are willing and capable of providing care to HIV-infected or exposed infants and children.

The minimum single oral metronidazole dose for treating trichomoniasis: a randomized, blinded study.

OBJECTIVE: To identify the minimum effective single oral dose of metronidazole for trichomoniasis. METHODS: Women attending an inner-city sexually transmitted disease clinic who had Trichomonas vaginalis vaginitis diagnosed by microscopy were recruited for this randomized, double-blind study. Subjects were given a 0.5-, 1-, 1.5-, or 2-g single oral dose of metronidazole, taken under direct observation. Demographic information, symptoms, and clinical findings were collected from patient interviews, and physical examinations were conducted at the time of enrollment and at the follow-up visit. The primary outcome measure was treatment success at the follow-up visit, established by negative culture and microscopy. RESULTS: Three (1.8%) of the 167 women enrolled were excluded because of vomiting after taking metronidazole, and 66 (40%) of the 164 remaining subjects did not return for the follow-up visit. No associations were found between the proportion of subjects lost to follow-up and the characteristics of these subjects across assignment groups. The treatment success ratio was highest in subjects who received the 1.5-g dose (23, 85%), followed by the 2-g (16, 84%), 1-g (18, 62%), and the 0.5-g dose (8, 35%). CONCLUSION: A single 1.5-g dose of metronidazole has efficacy equivalent to a single 2-g dose for the treatment of T vaginalis vaginitis.

Substance use in an inner-city family planning population.

OBJECTIVE: To determine the prevalence of drug and alcohol use in an inner-city family planning population and to identify variables associated with a positive urine screen. STUDY DESIGN: We conducted blind urine drug and alcohol screening in 309 women attending an inner-city hospital family planning clinic. RESULTS: The prevalence of a positive urine drug and/or alcohol screen was 15.5% (48/309). Specific substance positivity rates were: marijuana 9.4%, cocaine 4.9%, alcohol 1.3%, benzodiazepines 1.0%, opiates 1.0% and amphetamines 0.3%. After controlling for other independent variables, increased age was the only predictor of having a positive drug and/or alcohol screen, while increased age and a history of a sexually transmitted disease predicted the use of drugs other than marijuana or alcohol alone. CONCLUSIONS: Our findings support the concept that substance use histories and urine drug screening should be considered in patients seeking family planning services. This strategy can lead to counseling and treatment for a population seeking preventive care that might otherwise not be identified.

PIP: During February-June 1992, in Pennsylvania, health workers collected urine specimens from 309 women attending an inner city hospital family planning clinic in Philadelphia so researchers could determine the prevalence of drug and alcohol use in this population and to identify the variables associated with a positive urine screen for drugs and/or alcohol. 48 (15.5%) tested positive for at least one drug metabolite or alcohol. Six (2%) tested positive for at least two substances. The most frequent substances included marijuana (9.4%) and cocaine (4.9%). Other prevalence rates were 1.3% for alcohol, 1% for benzodiazepines and opiates, and 0.3% for amphetamines. The logistic regression revealed that increasing age was the only variable that predicted women having a positive urine drug and/or alcohol screen (odds ratio [OR] = 1.09). Women older than 29 years old had the highest prevalence of recent drug or alcohol use (25.4%). Increased age and history of a sexually transmitted disease (STD) were predictors of use of drugs other than marijuana or alcohol alone (OR = 1.17 and 2.18, respectively). Overall condom use stood at only 24%. Women who screened positive for drugs other than marijuana and alcohol alone had the lowest rates of current condom use (5% vs. 29%) and the highest rate of a history of an STD (70% vs. 29%). These findings indicate a need for family planning providers to screen for drugs and alcohol and to take substance use histories to identify the population at risk. Thus they will be able to provide counseling and treatment referrals, when appropriate, for a population seeking preventive care that might otherwise not be identified.
