Mentally ill Medicare patients less likely than others to receive certain types of surgery

Mentally ill people may face barriers to receiving elective surgical procedures as a result of societal stigma and the cognitive, behavioral, and interpersonal deficits associated with mental illness. Using data from a cohort of elderly Medicare beneficiaries in 2007, we examined whether the mentally ill have less access than people without mental illness to several common procedures that are typically not for emergencies and are performed at the discretion of the provider and the patient. Results suggest that Medicare patients with mental illness are 30-70?percent less likely than others to receive these "referral-sensitive" surgical procedures. Those who did undergo an elective procedure generally experienced poorer outcomes both in the hospital and after discharge. Efforts to improve access to and outcomes of nonpsychiatric care for mentally ill patients are warranted.     

Drug coverage,utilization, and spending by Medicare beneficiaries with heart disease

For Medicare beneficiaries who report having heart disease, drug coverage and type of supplemental health insurance affect the likelihood of usage and costs of heart medications, but not the extent of usage. Nearly one in five does not use heart medications and of the latter, one-third lack drug coverage. Some non-users without drug coverage go without prescribed heart medications because of limited financial access. Compared to non-users with coverage, they utilize medical provider services more, and if hospitalized, their inpatient costs are twice as high. Medicare may accrue cost savings by providing drug coverage to and monitoring these at-risk beneficiaries.     

Pregnant African-American teens are less likely than their nonpregnant peers to use condoms

OBJECTIVE: The aim of this study was to prospectively compare pregnant and nonpregnant adolescents' recent condom use and sexually transmitted disease (STD) acquisition. METHODS: Sexually active African-American females (N = 522), ages 14-18, were recruited from clinics and schools. Adolescents completed baseline interviews and provided vaginal swabs for STD testing, and urine for pregnancy testing. Assessments were repeated 6 and 12 months post baseline assessment. Analyses compared adolescents who became pregnant between baseline and the 6-month assessment with their peers who had negative pregnancy tests. Condom use between the 6- and 12-month assessments and incidence of STDs at the 12-month assessment served as outcomes. Adolescents who did not report sexual activity between the 6- and 12-month assessments were excluded. RESULTS: Ten percent of the adolescents became pregnant and continued sexual activity. Pregnant adolescents reported less overall condom use (P < 0.0001), more infrequent condom use (adjusted odds ratio [AOR] = 4.5, P < 0.001), and more unprotected vaginal sex (AOR = 4.7, P < 0.003). Pregnant adolescents were equally likely to test positive for STDs (31% vs 26%) and to self-report having STDs at the 12-month follow-up period (30% vs 23%). CONCLUSIONS: Findings suggest that pregnant adolescents may be less likely to use condoms than their nonpregnant peers and that STD incidence among pregnant adolescents may be high. Condom use promotion may be important during adolescents' prenatal care.     

Racial and ethnic differences in public and private medical care expenditures among aged Medicare beneficiaries

This study examines the current allocation of medical care expenditures among non-Hispanic white, non-Hispanic black, and Hispanic seniors who are Medicare beneficiaries. Analyses of both "need-based" and "demand-based" perspectives found that white, black, and Hispanic seniors in similar health had similar total annual expenditures for medical care. The groups did, however, differ substantially in the distribution of expenditures between public and private sources of payment. Notably, racial and ethnic differences in public and private expenditures all but vanished when socioeconomic variables and health insurance coverage were included in the analyses. The findings suggest that public sources of payment for medical care services, especially public supplementary coverage have helped to eliminate racial and ethnic gaps in expenditures.     

Implanon users are less likely to be satisfied with their contraception after 6 months than IUD users

Background

The study was conducted to perform a direct comparison of the satisfaction of intrauterine device (IUD) users and Implanon users after 6 months.

Study design

Women were recruited to this study in the contraception clinics of Southern Health and Family Planning Victoria. Each woman completed a questionnaire at the time of starting her contraception with either an IUD or Implanon. Women were sent a follow-up questionnaire after 6 months to assess their satisfaction with their chosen method of contraception.

Results

A total of 439 participants were recruited for this non randomized cohort study; 211 choosing an IUD and 228 choosing to use Implanon. The main reason patients in both groups chose their contraceptive method was recommendation by the doctor. Follow-up was achieved in over 84% in both groups. More than 50% of women in both groups reported at least one side effect. The most commonly reported side effect in both groups was abnormal bleeding and this was also the most common reason for having the contraceptive device removed. The IUD users reported a higher rate of satisfaction with their chosen method of contraception, although there was no difference between groups in the removal rate or whether the women would recommend the contraception to others.

Conclusions

IUD users reported a higher level of satisfaction than did Implanon users at 6 months. Side effects in women using IUDs and Implanon are common. The range of likely side effects should be included in counseling women about long-term reversible contraception.     

Are smokers with alcohol disorders less likely to quit?

OBJECTIVES. This study examined the likelihood of smoking cessation in smokers with a prior history of alcoholism. METHODS. Data came from an epidemiologic study of 1007 young adults, randomly selected from those insured in a large health maintenance organization (HMO) in southeast Michigan. Cox proportional hazards models with time-dependent covariates were used to estimate the hazards ratios of quitting in smokers with current and past alcoholism, with smokers with no history of alcoholism as a reference. Sex, race, and education were controlled. RESULTS. Smokers with active alcoholism in the preceding year were 60% less likely to quit than were smokers with no history of alcoholism. In contrast, smokers whose alcoholism had remitted were at least as likely to quit as smokers with no history of alcoholism. Compared with persistent alcoholism, remission of alcoholism was associated with more than a threefold increase in the likelihood of subsequent smoking cessation. CONCLUSIONS. The findings suggest that discontinuation of alcoholism might increase the potential for successful smoking cessation.     

Uropathogenic Escherichia coli are less likely than paired fecal E. coli to have CRISPR loci

CRISPRs (Clustered Regularly Interspaced Short Palindromic Repeats) are short fragments of DNA that act as an adaptive immune system protecting bacteria against invasion by phages, plasmids or other forms of foreign DNA. Bacteria without a CRISPR locus may more readily adapt to environmental changes by acquiring foreign genetic material. Uropathogenic Escherichia coli (UPEC) live in a number of environments suggesting an ability to rapidly adapt to new environments. If UPEC are more adaptive than commensal E. coli we would expect that UPEC would have fewer CRISPR loci, and – if loci are present – that they would harbor fewer spacers than CRISPR loci in fecal E. coli. We tested this in vivo by comparing the number of CRISPR loci and spacers, and sensitivity to antibiotics (resistance is often obtained via plasmids) among 81 pairs of UPEC and fecal E. coli isolated from women with urinary tract infection. Each pair included one uropathogen and one commensal (fecal) sample from the same female patient.Fecal isolates had more repeats (p = 0.009) and more unique spacers (p < 0.0001) at four CRISPR loci than uropathogens. By contrast, uropathogens were more likely than fecal E. coli to be resistant to ampicillin, cefazolin and trimethoprim/sulfamethoxazole. However, no consistent association between CRISPRs and antibiotic resistance was identified. To our knowledge, this is the first study to compare fecal E. coli and pathogenic E. coli from the same individuals, and to test the association of CRISPR loci with antibiotic resistance. Our results suggest that the absence of CRISPR loci may make UPEC more susceptible to infection by phages or plasmids and allow them to adapt more quickly to various environments.     

Despite small improvement, black nursing home residents remain less likely than whites to receive flu vaccine

Vaccination is a key deterrent to influenza and its related complications and outcomes, including hospitalization and death. Using 2006-09 data, we found a small improvement in vaccination rates among nursing home residents, particularly for blacks. Nonetheless, overall vaccination rates remained well below the 90 percent target for high-quality care, and black nursing home residents remained less likely to be vaccinated than whites. Blacks were less likely to be vaccinated than were whites in the same facility and were more likely to live in facilities with lower vaccination rates. Blacks were also more likely to be noted as refusing vaccination. Strategies are needed to ensure that facilities offer vaccination to all residents and to make vaccination more acceptable to black residents and their families.     

Trends in care practices and outcomes among Medicare beneficiaries with diabetes

BACKGROUND: While diabetes is a major issue for the aging U.S. population, few studies have described the recent trends in both preventive care practices and complications among the Medicare population with diabetes. Using the Medicare Quality Monitoring System (MQMS), this 2004 study describes these trends from 1992 to 2001 and how these rates vary across demographic subgroups. METHODS: Outcomes include age- and gender-adjusted rates of 15 indicators associated with diabetes care from 1992 to 2001, the absolute change in rates from 1992 to 2001, and 2001 rates by demographic subgroups. The data were cross-sectional samples of Medicare beneficiaries with diabetes from 1992 to 2001 from the Medicare 5% Standard Analytic Files. RESULTS: Use of preventive care practices rose from 1992 to 2001: 45 percentage points for HbA1c tests, 51 for lipid tests, 8 for eye exams, and 38 for self-monitoring of glucose levels (all p<0.05). Rates for short-term and some long-term complications of diabetes (e.g., lower-extremity amputations and cardiovascular conditions) fell from 1992 to 2001 (p<0.05). However, rates of other long-term complications such as nephropathy, blindness, and retinopathy rose during the period (p<0.05). Nonwhites and beneficiaries aged <65 and >85 exhibited consistently higher complication rates and lower use of preventive services. CONCLUSIONS: The Medicare program has seen some significant improvement in preventive care practices and significant declines in lower-limb amputations and cardiovascular conditions. However, rates for other long-term complications have increased, with evidence of subgroup disparities. The MQMS results provide an early warning for policymakers to focus on the diabetes care provided to some vulnerable subgroups.     

Integrated telehealth and care management program for Medicare beneficiaries with chronic disease linked to savings

Treatment of chronically ill people constitutes nearly four-fifths of US health care spending, but it is hampered by a fragmented delivery system and discontinuities of care. We examined the impact of a care coordination approach called the Health Buddy Program, which integrates a telehealth tool with care management for chronically ill Medicare beneficiaries. We evaluated the program's impact on spending for patients of two clinics in the US Northwest who were exposed to the intervention, and we compared their experience with that of matched controls. We found significant savings among patients who used the Health Buddy telehealth program, which was associated with spending reductions of approximately 7.7-13.3 percent ($312-$542) per person per quarter. These results suggest that carefully designed and implemented care management and telehealth programs can help reduce health care spending and that such programs merit continued attention by Medicare. Meanwhile, mortality differences in the treatment and control groups suggest that the intervention may have produced noticeable changes in health outcomes, but we leave it to future research to explore these effects fully.
