Minimizing hair dispersal: Is this an opportunity for improvement in health care-acquired infection prevention?

We performed a study to understand common practices in surgical site hair removal and barriers to guideline compliance in surgical site hair removal. We found most health care providers in the United States do not remove hair outside of the operating room. Our findings reveal minimizing hair dispersal in the operating room, including improved and innovative ways for collecting clipped loose hair, is a significant area for improvement in surgical quality and health care-acquired infection prevention.

Clinical outcomes and adherence to medications measured by claims data in patients with diabetes.

OBJECTIVE: Although poor medication adherence may contribute to inadequate diabetes control, ways to feasibly measure adherence in routine clinical practice have yet to be established. The present study was conducted to determine whether pharmacy claims-based measures of medication adherence are associated with clinical outcomes in patients with diabetes. RESEARCH DESIGN AND METHODS: The study setting was a large, integrated delivery and financial system serving the residents of southeastern Michigan. The study population consisted of 677 randomly selected patients aged > or =18 years with a diagnosis of diabetes, hypercholesterolemia, and hypertension and who filled at least one prescription for either an antidiabetic, lipid-lowering, or antihypertensive drug in each of the 3 study years (1999-2001). The main outcome measures were HbA1c, LDL cholesterol levels, and blood pressure. RESULTS: Nonadherent patients had both statistically and clinically worse outcomes than adherent patients. Even after adjusting for demographic and clinical characteristics, nonadherence was significantly associated with HbA1c and LDL cholesterol levels. A 10% increase in nonadherence to metformin and statins was associated with an increase of 0.14% in HbA1c and an increase of 4.9 mg/dl in LDL cholesterol levels. Nonadherence to ACE inhibitors was not significantly associated with blood pressure. CONCLUSIONS: Claims-based measures of medication adherence are associated with clinical outcomes in patients with diabetes and may therefore prove to be useful in clinical practice. More research is needed on methods to introduce claims-based adherence measurements into routine clinical practice and how to use these measurements to effectively improve adherence and health outcomes in chronic care management.

Risk factors for emergency department use among children with asthma using primary care in a managed care environment.

OBJECTIVE: To identify risk factors for emergency department (ED) use among children with asthma using primary care in a managed care environment. DESIGN: Using automated data sources, children with asthma were identified and followed for 2-year periods. We fit logistic regression models using generalized estimating equation approaches to identify ED risk factors. PATIENTS: Children with asthma aged 5-14 with a visit to a pediatrician practicing with a large group practice and enrolled in an HMO for 2 consecutive years between 1992 and 1996 (N = 411 children). MAIN OUTCOME MEASURES: Asthma-related ED use. RESULTS: Twenty-three percent of children incurred an asthma-related ED visit. Asthma-related ED use was greater among children with prior asthma-related ED use (OR [odds ratio] = 8.26, 95% CI [confidence interval] = 4.79-14.25), decreased with increasing age (OR = 0.87, 95% CI = 0.79-0.96) and frequency of visits to a primary care physician for asthma (OR = 0.82, 95% CI = 0.70-0.96), and tended to be less among children who saw an allergist (OR = 0.59, 95% CI = 0.33-1.04). No significant relationship was found between asthma-related ED use and race, household income, or other patient characteristics. CONCLUSIONS: Targeting children with prior asthma-related ED use and encouraging routine primary care visits as well as the use of an allergist may afford opportunities to reduce ED use among children with asthma currently receiving primary care.

Race-ethnicity, crime, and other factors associated with adherence to inhaled corticosteroids.

BACKGROUND: Previous studies have shown differences in adherence to inhaled corticosteroids (ICSs) by race-ethnicity, yet little is known about factors that contribute to adherence within these groups. Environmental stressors, such as crime exposure, which has been associated with asthma morbidity, might also predict ICS adherence. OBJECTIVE: We sought to identify factors associated with ICS adherence among patients with asthma and among African American patients and white patients separately. METHODS: Study patients with asthma were aged 18 to 50 years and were enrolled in a large southeast Michigan health maintenance organization between January 1, 1999, and December 31, 2001. The primary outcome, ICS adherence, was calculated by linking prescription-fill data with dosage information. Predictor variables included age, sex, race-ethnicity, measures of socioeconomic status (SES), average ICS copay, existing comorbidities, and crime rate in area of residence. RESULTS: Adherence information was available for 176 patients. ICS adherence was lower among African American patients (n = 75) when compared with white patients (n = 94; 40% vs 58%, respectively; P = .002). Among white patients, adherence was significantly lower for women when compared with men. Among African American patients, age and residential crime rates were positively and negatively associated with ICS adherence, respectively. Area crime remained a predictor of adherence in African American patients, even after adjusting for multiple measures of SES. CONCLUSIONS: This study suggests that an environmental stressor, area crime, provides additional predictive insight into ICS-adherent behavior beyond typical SES factors. CLINICAL IMPLICATIONS: Better understanding of environmental factors that influence ICS adherence might aid in efforts to improve it.

The use of computerized birthday greeting reminders in the management of diabetes.

BACKGROUND: Although mailed reminders have been used for prevention among general populations, few studies have evaluated their effectiveness among chronically ill populations. OBJECTIVE: We evaluated the effectiveness of mailed reminders for improving diabetes management. The reminder included a letter from the individual's primary care physician (PCP), a self-care handbook, a preventive care checklist, and specific recommendations regarding receipt of routine monitoring and screening. METHODS: Of 195 PCPs practicing with a large group practice, 111 agreed to have their adult patients with diabetes randomized to receive the reminder (n = 1,641) or usual care (n = 1,668). Using data from automated databases, we fit generalized estimating equations to evaluate the effect of reminder receipt on fasting lipid profile and glycated hemoglobin testing, dilated retinal exam receipt, and visit frequency during the 6 and 12 months following randomization, and glycated hemoglobin and cholesterol levels in the year following randomization. RESULTS: Reminder and usual care recipients did not differ in sociodemographic, clinical, or prior testing characteristics. In the 6 months following randomization, reminder recipients were more likely to receive a retinal exam (odds ratio [OR], 1.29; 95% confidence interval [95% CI], 1.12 to 1.49) and diabetes visit (OR, 1.28; 95% CI, 1.12 to 1.47). In the 12 months following randomization, reminder recipients were more likely to receive a glycated hemoglobin test (OR, 1.21; 95% CI, 1.03 to 1.43), retinal exam (OR, 1.23; 95% CI, 1.07 to 1.41), and diabetes visit (OR, 1.25; 95% CI, 1.09 to 1.29). In the follow-up year, reminder recipients also tended to have a glycated hemoglobin test that did not reflect poor control (<9.5%). CONCLUSIONS: We found small but significant improvements in the management of patients with diabetes receiving a computerized mailed reminder.

Relationship between adherence to inhaled corticosteroids and poor outcomes among adults with asthma.

BACKGROUND: Regular use of inhaled corticosteroids (ICSs) can improve asthma symptoms and prevent exacerbations. However, overall adherence is poor among patients with asthma. Objective To estimate the proportion of poor asthma-related outcomes attributable to ICS nonadherence. METHODS: We retrospectively identified 405 adults age 18 to 50 years who had asthma and were members of a large health maintenance organization in southeast Michigan between January 1, 1999, and December 31, 2001. Adherence indices were calculated by using medical records and pharmacy claims. The main outcomes were the number of asthma-related outpatient visits, emergency department visits, and hospitalizations, as well as the frequency of oral steroid use. RESULTS: Overall adherence to ICS was approximately 50%. Adherence to ICS was significantly and negatively correlated with the number of emergency department visits (correlation coefficient [ R ] = -0.159), the number of fills of an oral steroid ( R = -0.179), and the total days' supply of oral steroid ( R = -0.154). After adjusting for potential confounders, including the prescribed amount of ICS, each 25% increase in the proportion of time without ICS medication resulted in a doubling of the rate of asthma-related hospitalization (relative rate, 2.01; 95% CI, 1.06-3.79). During the study period, there were 80 asthma-related hospitalizations; an estimated 32 hospitalizations would have occurred were there no gaps in medication use (60% reduction). CONCLUSIONS: Adherence to ICS is poor among adult patients with asthma and is correlated with several poor asthma-related outcomes. Less than perfect adherence to ICS appears to account for the majority of asthma-related hospitalizations.
