The relationship between local clean indoor air policies and smoking behaviours in Minnesota youth.

BACKGROUND: While clean indoor air (CIA) policies are intended to reduce exposure to second-hand smoke in the workplace, restrictions in public workplaces have the potential to discourage youth smoking. There is growing evidence from cross-sectional and ecological studies, but limited evidence from longitudinal studies that this is so. OBJECTIVE: To evaluate the association between local CIA policies and smoking behaviours among Minnesota youth over time. DESIGN, SETTING AND SUBJECTS: A cohort of 4233 Minnesota youths, ages 11 to 16 at baseline, was interviewed via telephone for 6 years (2000-2006). Individual, family and community level variables were collected from participants every 6 months. A generalised estimating equation (GEE) logistic regression was used to assess the relationship between CIA policies and past-month smoking in youth over time. The analysis was controlled for potential confounders at individual and community levels. RESULTS: There was not significant association between CIA policies and youth smoking behaviours in the multivariate analyses. At the individual level, parental smoking significantly increased the odds of smoking nearly 40% and close friend smoking increased the odds of past-month smoking by nearly 100% for each close friend. Banning smoking in the home was significantly associated with a 12% reduction in the odds of past-month smoking. CONCLUSION: After accounting for other community and individual level factors known to be associated with youth smoking, there was no significant association between CIA policies and past-month smoking for youth over time.

Does the type of CIA policy significantly affect bar and restaurant employment in Minnesota cities?

Clean indoor air (CIA) policies that include free-standing bars and restaurants have been adopted by communities to protect employees in all workplaces from exposure to environmental tobacco smoke, most notably employees working in restaurants and free-standing bars. However, due to the perception of negative economic effects on alcohol-licensed hospitality businesses, partial CIA policies (those that provide an exemption for free-standing bars) have been proposed as a means to reduce the risk of economic effects of comprehensive CIA policies applied to all worksites. Bar and restaurant employment per capita were used to determine if partial CIA policies produced differential economic effects compared to comprehensive CIA policies. Ten cities in the state of Minnesota were studied from 2003-2006. Economic data were drawn from monthly employment in bars and restaurants, and a pooled time-series was completed to evaluate three types of local CIA policies: Comprehensive, partial, or none beyond the state law. Communities with a comprehensive CIA policy had a decrease of 9 employees per 10,000 residents compared with communities with partial CIA policies (p = 0.10). Communities with any type of CIA policy (partial or comprehensive) had an increase of 3 employees per 10,000 residents compared to communities without any CIA policies (p = 0.36). There were no significant differential economic effects by CIA policy type in Minnesota cities. These findings support the adoption of comprehensive CIA policies to provide all employees protection from environmental tobacco smoke exposure.

Selective serotonin reuptake inhibitor utilization patterns: consistency across research designs.

We examined the impact of commonly applied selection criteria on the ability of patients who are initiating antidepressant therapy to reach a stable pattern, which was defined as receipt of only the initial agent at the initial dose for 90 or more consecutive days. Patients in a large US prescription database who initiated fluoxetine, paroxetine, or sertraline therapy between February and April of 1995 were categorized as with (typical design) and without (relaxed design) commonly applied selection criteria. The percentage of patients achieving a stable pattern was then determined. We found that this percentage was significantly higher with the relaxed design (typical, 28.8%; relaxed, 32.4%) and for patients initiating fluoxetine therapy (>5.5% higher than for those initiating paroxetine or sertraline therapy). The results for fluoxetine were consistent across designs, whereas comparisons between paroxetine and sertraline yielded mixed results. Therefore, the relative relationship of the stable pattern is robust across designs for fluoxetine but not for paroxetine and sertraline. Further, application of commonly applied selection criteria may make a sample less representative and reduce the measured rates of stable antidepressant use, potentially leading to underestimation of the benefits of pharmacotherapy.

A community-based collaboration to assess and improve medical insurance status and access to health care of Latino children.

OBJECTIVES: Despite eligibility for subsidized insurance, low-income Latino children are at high risk of being medically uninsured. The authors sought to understand and improve access to medical insurance for Latino children living in a California community of predominantly low-income immigrant families. METHODS: During the summer of 1999, trained women from the community conducted interviews in Spanish with 252 randomly selected mothers of 464 children younger than age 19. Mothers provided information about family demographics, children's medical insurance, health care access, and experiences obtaining and maintaining children's insurance. RESULTS: Most children (83.3%) were eligible for subsidized medical insurance (48.4% Medi-Cal eligible; 35.0% Healthy Families eligible). Twenty-eight percent of eligible children were not enrolled. Non-enrolled eligible children were older (median age 7) than enrolled children (median age 4) and more likely to be born outside the U.S. (22.2%) than enrolled children (4.8%). Among children ages 3-18, those not enrolled were less likely to have visited a doctor in the past 12 months (58% compared to 78.7%) and less likely to have a usual source of care (96.3% compared to 99.5%). Mothers of non-enrolled children were more likely than mothers of enrolled children to have less than seven years of education (47.8% compared to 36.4%). Families with non-enrolled children were more likely to report out-of-pocket medical expenses (84.1% compared to 53%). Families with non-enrolled children were more likely to report barriers to the enrollment process, such as problems providing required documents (39.7% compared to 15.1%), problems understanding Spanish forms (19.4% compared to 8.9%), and confusing paperwork (39.7% compared to 24.7%). Most mothers (75.9%) reported that community organizations provided very useful help with children's insurance enrollment. Almost half (48.6%) preferred to receive enrollment assistance from community organizations. Only 43.3% of mothers had heard of the Healthy Families program. CONCLUSIONS: To reach the majority of uninsured Latino children, community-based outreach and insurance application assistance are crucial. Most important, the process of applying for and maintaining coverage in Medi-Cal or Healthy Families must be simplified.

Methicillin-resistant Staphylococcus aureus: a descriptive analysis on veterans.

Concern over complications of a potentially large outbreak of methicillin-resistant Staphylococcus aureus (MRSA) prompted intensive monitoring and establishment of effective communication lines between infection control practitioners, nurses, physicians, and microbiology personnel. From October, 1986, through September, 1987, 77 patients at the Veterans Administration Medical Center in Oklahoma City had MRSA. Charts were available for review on 63 of these patients. When those with charts available were reviewed, 41 patients had nosocomial (NC) and 22 had community-acquired (CA) MRSA. Of the 41 NC patients, 34 were infected (of which 17 died during hospitalization) and 7 colonized (3 died). Of the 22 CA patients, 15 were infected (4 died) and 7 colonized (2 died). Length of stay was NC-infected, mean 51.8 days; NC-colonized, 38.9 days; CA-infected, 14.9 days; and CA-colonized, 16.1 days. This study shows the importance of NC MRSA, especially as it relates to hospital costs and care of many extended stay patients.

Medication cart-filling time, accuracy, and cost with an automated dispensing system.

Medication cart filling with an automated dispensing system was compared with manual cart filling with respect to personnel time, costs, and accuracy. At a 650-bed tertiary-care medical center, technician cart filling and pharmacist cart checking were timed for the existing manual system and for the Baxter ATC-212 automated dispensing system. Subsequently, carts filled with each system were checked for accuracy of dispensing. On the basis of drugs used in the automated system over three months, drug acquisition and dispensing costs were calculated for automated and manual cart filling; the costs of personnel time were also compared. Daily cart filling time for technicians was significantly less with the automated system. The savings of pharmacist time was not significant; pharmacists had to cut the strip-packaged drugs into individual doses as they checked patients' medications. For both systems, errors were found in fewer than 1% of the doses (0.84% for the manual system and 0.65% for the automated system). Drug costs were higher with the automated system; acquisition prices for the bulk drugs purchased for use in the dispensing machine were higher than the prices of the same products in unit dose packaging. Personnel time saved amounted to less than 0.5 full-time equivalent. With the automated system, overall time savings was not great enough to substantially affect pharmacy operations, and drug costs were higher.

Salmonella newport infections transmitted by fiberoptic colonoscopy.

During a 2-week period following the colonoscopy and biopsy of a patient with acute Salmonella newport gastroenteritis, S. newport was recovered from colonic aspirates or fecal specimens of eight of 28 patients from whom specimens were cultured during or after colonoscopy. Two of the eight persons from whom S. newport was isolated developed acute gastroenteritis, two had asymptomatic infections, and four had positive aspirates collected through a colonoscope but did not become infected. Although S. newport was never recovered from the four colonoscopes used during the outbreak, cultures of one of the colonic biopsy forceps grew S. newport. Contamination of the equipment most likely occurred during colonoscopy of the index patient. Inadequate disinfection of the equipment allowed the organism to survive and possibly to cross-contaminate other colonoscopes, and the organism was then transmitted to other patients by use of the contaminated colonoscopes or the contaminated biopsy forceps. Implemented control measures terminated the outbreak.

Lanepitant, an NK-1 antagonist, in migraine prevention.

Lanepitant, a potent non-peptide neurokinin-1 receptor antagonist, inhibits neurogenic dural inflammation, and may have a role in migraine therapy. This study evaluated the effect of lanepitant taken daily for migraine prevention. Patients with migraine headaches with and without aura by International Headache Society classification criteria were enrolled in a 12-week double-blind, parallel design study comparing the effect of 200 mg qd lanepitant (n = 42) and placebo (n = 42) on reduction of migraine frequency. The primary outcome measure was response rate, i.e. the proportion of patients with a 50% reduction in days of headache. Of the 84 patients enrolled, 90.5% were female. The endpoint response rate for lanepitant-treated patients (41.0%) was not statistically significantly (P = 0.065) greater than that for placebo-treated patients (22.0%). No efficacy variables differed significantly between treatments, except for response rates at month 3 (P = 0.045). Higher plasma concentrations were no more effective than lower concentrations. In this study lanepitant was not effective in preventing migraine, but was well tolerated. These results do not support a role for NK-1 antagonism in migraine prevention.
