OBJECTIVE: A review of the evidence was conducted regarding asthma associated with the use of cocaine, heroin, and marijuana. DATA SOURCES: A search of the English literature was performed via PubMed/Medline and EMBASE using the search terms asthma AND cocaine, heroin, and marijuana. When pertinent articles were found, salient references in those articles were assessed. STUDY SELECTION: Due to the relatively small number of studies, we included all studies and cases. RESULTS: For several decades, case reports, retrospective studies, and laboratory investigations have demonstrated that inhalation of cocaine or heroin is associated with increased asthma symptoms and reduced pulmonary function. Smoking crack cocaine, nasal insufflation of cocaine or heroin, and smoking heroin increases the risk of emergency department visits and hospitalizations for asthma. Although frequent smoking of marijuana may cause symptoms of cough, sputum production, and wheezing in the general population, more studies are needed specifically in patients with asthma. Smoking marijuana with concomitant tobacco use is common and further worsens the respiratory symptoms. CONCLUSIONS: Use of cocaine and heroin in patients with asthma should be avoided. Pending further studies, it would be prudent for patients with asthma to avoid smoking marijuana. Clinicians need to be vigilant regarding use of these drugs in their patients with hyperreactive airway disease.

Background: Treatment with an aldosterone antagonist (AA) has been shown in multiple trials to reduce heart failure (HF)-related morbidity, mortality, and hospital readmission. American College of Cardiology Foundation (ACCF) and American Heart Association (AHA) treatment guidelines recommend the use of an AA in all HF patients with an ejection fraction ≤35% and no known contraindication. Several studies have documented underuse of AA. Objectives: To determine the proportion of patients who received AA therapy consistent with the ACCF/AHA guidelines. Secondary objectives included determining the proportion of patients who received an AA inconsistent with guidelines and 30- and 90-day readmission rates. Methods: A retrospective chart review was conducted of patients admitted to an inner city academic medical center with a diagnosis of HF between August 16, 2011, and June 5, 2013. Results: A total of 346 HF admissions (87.6% African American) were evaluated. Use of an AA at discharge was consistent with guidelines in 31% of patients. A total of 121 patients (35%) were discharged on an AA. Among the remaining 225 patients who were not discharged on an AA, 170 (75.6%) had no contraindication to therapy. Sixty-one patients were readmitted within 30 days, and a total of 108 patients were readmitted within 90 days. There were no significant differences in readmission rates between patients who were discharged on AA therapy and those who were not. Conclusion: AAs are still underutilized in the treatment of HF.
RESUMO
Asthma is a frequent comorbidity in hospitalized children and adults. Patients with a history of asthma may have no breathing complaints or abnormal chest exam findings to trigger care for this comorbidity during hospitalization. Consequently, this may lead to a potential missed opportunity to discuss asthma as a comorbidity and ongoing issue to ensure its optimal management at home. Our goal is to raise awareness that such patient encounters may represent opportunities for health care professionals to optimize asthma management. Despite focusing on the present illness and limited time availability, asthma care may be improved in a time-efficient manner in these patients.

OBJECTIVES: Numerous factors are well documented to affect the response to vitamin K antagonists (VKA), including dietary vitamin K, other drugs, age, pharmacogenetics, and disease states. Body weight is perhaps not as well known as a variable affecting VKA dose. Our aim was to review the literature regarding body weight and VKA dose requirements. METHODS: We reviewed the English-language literature via PubMed and Scopus using the search terms VKA, warfarin, acenocoumarol, phenprocoumon, fluindione, AND body weight. RESULTS: Among 32 studies conducted since the widespread use of the international normalized ratio, 29 found a correlation with body weight or body surface area and VKA dose requirement. Warfarin was evaluated in 27 studies and acenocoumarol, phenprocoumon, or fluindione were assessed in 5 investigations. CONCLUSIONS: Because of varying study methodologies, further study is warranted. Based on current evidence, clinicians should include body weight, along with other established variables when dosing VKA. Most important, obese and morbidly obese patients may require a 30% to 50% increase with the initial dosing of VKA.

BACKGROUND: Hospitalized patients with chronic obstructive pulmonary disease (COPD) or asthma routinely have inhaled medications ordered for acute and maintenance therapy. Treatment may be administered via metered-dose inhaler (MDI) or dry-powder inhaler (DPI). These products must be appropriately labeled to be released home with the patient or discarded before discharge. OBJECTIVE: To assess the amount and estimated cost of wasted doses of medications via MDI or DPI for hospitalized patients with COPD/asthma. METHODS: A retrospective study was conducted at a university-affiliated hospital. Patients admitted between January 2011 and June 2012 with a primary diagnosis of COPD or COPD with asthma and who were ≥40 years of age were included. Information collected included use of albuterol, ipratropium, inhaled corticosteroids, long-acting beta agonist, or tiotropium and whether treatments were given by nebulizer, MDI, MDI plus valved holding chamber (VHC), or DPI. The number of doses dispensed, as well as doses not used, via MDI, MDI + VHC, or DPI were collected from electronic medical records. Costs associated with wasted medications were evaluated. RESULTS: Of 555 patient admissions screened, 478 (mean age, 66 years; 58% women; 74% African American) met study criteria. Of the total MDI or DPI doses dispensed, 87% were wasted, and associated hospital cost was approximately $86,973. CONCLUSIONS: Substantial waste of inhaled medications was found in our study. Practical strategies are needed to reduce wasted inhalers. Further assessment of this problem is needed in other US hospitals.
RESUMO
BACKGROUND: Monitoring peak expiratory flow (PEF) values is one option as part of asthma action plans per national guidelines. PEF assessment is also recommended in emergency department and hospitalized patients. Incorrect use of peak flow meters (PFM) has obvious implications for appropriate decisions by patients and clinicians. METHODS: We searched the English literature via PubMed and SCOPUS using the following search terms: PEF maneuver; incorrect use of PFM. When pertinent articles were found, we assessed publications cited in those papers. All studies related to incorrect use of PFM in patients with asthma were included. RESULTS: Nine studies have reported errors in performing the PEF maneuver, including three pediatric and six adult studies. Errors were found at most steps of the maneuver, and inability to perform all steps correctly was common in these investigations. Examples of errors included failure to inhale fully or give maximum effort on exhalation, accelerating air with the tongue and buccal musculature, and performing only one attempt versus three. Gender differences in correct use of PFM are suggested by three adult studies. One study described falsifying PEF values by manipulating the PFM indicator, and another investigation assessed the PEF maneuver in two positions in bed versus the correct posture of standing. CONCLUSION: Many pediatric and adult patients do not use PFM correctly. Clinicians should regularly observe patients use PFM to detect errors and help ensure correct use and accurate PEF measurements.

Nitrofurantoin is a commonly prescribed antibiotic for the treatment of recurrent uncomplicated urinary tract infections. Its importance has been emphasized by the current international clinical practice guidelines for the management of uncomplicated cystitis. Since its introduction into clinical practice, nitrofurantoin has been associated with various adverse effects, including hepatotoxicity. We searched the English-language literature using PubMed and SCOPUS for the period 1961 through the end of February 2013. Key search terms included "nitrofurantoin AND hepatotoxicity" as well as "nitrofurantoin AND hepatitis." When studies or case reports were found, we assessed articles cited in those publications. A broad spectrum of liver toxicity associated with nitrofurantoin use has been reported, ranging from acute hepatitis, granulomatous reaction, cholestasis, or autoimmune-mediated hepatitis to chronic active hepatitis that could lead to cirrhosis or death. The mechanism of hepatotoxicity is poorly understood, but it is believed to be the result of an immunologic process or a direct cytotoxic reaction. It has been postulated that prolonged exposure to nitrofurantoin, female sex, advanced age, and reduced renal function increase the risk of developing hepatotoxicity. For the management of severe cases, corticosteroids have been used along with nitrofurantoin discontinuation. Because of mixed results, the utility of corticosteroids has not been proven and should be used judiciously. Given the severity and seriousness of the adverse effect of hepatotoxicity, clinicians should weigh the risks and benefits of nitrofurantoin before initiating therapy, especially in long-term prophylaxis in high-risk patients. Clinicians also should be well versed in recognizing and managing liver injury associated with nitrofurantoin.

Achieving therapeutic anticoagulation with warfarin is complicated by substantial inter-patient and intra-patient variability with numerous factors known to influence dose requirements. Obesity is one factor for which there remains no study to date investigating its initial effect on warfarin response assessed by INR, stratified by BMI category in hospitalized patients. To compare initial warfarin response between obese and non-obese patients by evaluating average daily dose (ADD), time required to attain therapeutic INR, and mean discharge dose (MDD), stratified by BMI category. A retrospective review was conducted to evaluate initial warfarin response in hospitalized patients of different BMI categories initiated on warfarin with ≥4 consecutive days of therapy and managed by pharmacy dosing service. 211 patients were included (10 underweight, 45 normal weight, 48 overweight, 71 obese, 37 morbidly obese). Across BMI categories, the percentage of patients attaining therapeutic INR prior to discharge differed (p = 0.0004) with 71.1 % of normal weight therapeutic compared to 42.3 % of obese and 38 % of morbidly obese. Within BMI categories, when comparing ADD between patients therapeutic and subtherapeutic at discharge, no differences were observed, except among overweight patients (5.6 ± 0.3 vs. 7 ± 0.4 mg, p = 0.0143). Compared to normal weight, obese and morbidly obese required a significantly longer median time to achieve therapeutic INR (8 and 10 days vs. 6 days) and a higher ADD (6.6 ± 0.3 and 7.6 ± 0.5 vs. 5 ± 0.3 mg) and MDD (6.7 ± 0.5 and 6.7 ± 0.7 vs. 4.4 ± 0.5 mg). Compared to normal weight, obese and morbidly obese patients had a decreased initial response to warfarin.

BACKGROUND: Benefits outweigh risks of cardioselective beta-blocker therapy in patients with nonsevere asthma and a history of heart failure or myocardial infarction (MI). This review summarizes the risks versus benefits of using cardioselective beta-blockers in the treatment of hypertension in patients with asthma. METHODS: We searched the English literature from 1976 to 2011 via PubMed, EMBASE, and SCOPUS using the following search terms: "beta-blocker treatment of hypertension" AND "asthma"; "cardioselective beta-blockers" AND "asthma." When pertinent articles were found, we assessed relevant articles cited in those papers. All studies related to cardioselective beta-blocker use in patients with asthma and hypertension were included. RESULTS: Seven studies with patient populations ranging from 10 to 17 patients evaluated cardioselective beta-blockers in patients with asthma and hypertension. Atenolol and/or immediate-release metoprolol were evaluated in these studies. The duration of beta-blocker therapy in four studies was 1-8 weeks; two studies were single dose and one investigation lasted 8 months. Metoprolol and atenolol were generally well tolerated except at higher doses such as metoprolol >100 mg daily. CONCLUSION: In the absence of concomitant cardiovascular disease, routine use of beta-blockers for the treatment of hypertension in patients with asthma should be avoided.

OBJECTIVE: Chronic obstructive pulmonary disease (COPD) increasingly is a cause of morbidity and mortality in and economic burden on the US healthcare system, and COPD exacerbations continue to be among the top 10 causes of hospitalization in adults. The objective of this study was to evaluate the incidence and potential implications of missed scheduled nebulized bronchodilator therapy in the setting of acute, non-life-threatening COPD exacerbations. MATERIALS AND METHODS: This study was a retrospective chart review of all of the patients with a primary diagnosis of severe, non-life-threatening COPD exacerbations admitted from January 2007 to June 2008 at a university-affiliated hospital. Each patient's inhaled bronchodilator treatment regimen, including potential for nebulization to metered-dose inhaler (MDI) with valved holding chamber (VHC) conversion, was assessed. RESULTS: A total of 259 patients met inclusion criteria: 235 (90.7%) patients received inhaled bronchodilators by nebulization alone in the treatment of COPD exacerbations; 81.1% of these patients could have used MDI with VHC. Patients missed 24.3% of their scheduled, nebulized bronchodilator doses. CONCLUSIONS: Patient care can be improved through the initiation of MDI with VHC, especially considering the number of missed nebulizations that these patients experienced. Development of an inhaled bronchodilator treatment algorithm for COPD exacerbations should be considered to ensure an evidence-bassed medicine approach to these patients.

BACKGROUND: Oral corticosteroids (OCS) in the home management of asthma exacerbations have been recommended in the NIH/NHLBI guidelines since 1991. As a routine component of written action plans, OCS treatment at home is associated with reduced emergency department (ED) visits and hospitalizations as well as decreased mortality. METHODS: A literature search of English language journals from 1991 to 2009 was performed using several databases, including PubMed, EMBASE, and SCOPUS. We assessed studies that evaluated adherence to national guidelines for home management of asthma exacerbations. RESULTS: Our review of the literature found that several studies reveal that a small percentage (<3-26%) of patients are receiving OCS at home to manage asthma exacerbations prior to an ED visit. Additional studies were found showing very low use of written action plans, strongly suggesting lack of OCS for home management of asthma exacerbations. CONCLUSIONS: Despite evidence of reduced ED visits and hospitalizations and the recommendations of national and international guidelines, the home use of OCS in managing asthma exacerbations remains unacceptably low. New strategies are needed to ensure home use of OCS as part of written action plans to prevent ED visits and hospitalizations for asthma exacerbations.

National and International Guidelines concur that inhaled corticosteroids (ICS) are the preferred long-term maintenance drug therapy for mild persistent asthma for all ages. For moderate and severe persistent asthma, ICS are essential to optimal management, often concurrent with other key therapies. Despite strong evidence and consensus guidelines, ICS are still underused. While some patients who are treated in the emergency department (ED) have intermittent asthma, most have persistent asthma and need ICS for optimum outcomes. Failure to initiate ICS at this critical juncture often results in subsequent lack of ICS therapy. Along with a short course of oral corticosteroids, ICS should be initiated before discharge from the ED in patients with persistent asthma. Although the NIH/NAEPP Expert Panel Report 3 suggests considering the prescription of ICS on discharge from the ED, The Global Initiative for Asthma (GINA) 2008 guidelines recommend initiation or continuation of ICS before patients are discharged from the ED. The initiation of ICS therapy by ED physicians is also encouraged in the emergency medicine literature over the past decade. Misdiagnosis of intermittent asthma is common; therefore, ICS therapy should be considered for ED patients with this diagnosis with reassessment in follow-up office visits. To help ensure adherence to ICS therapy, patient education regarding both airway inflammation (show airway models/colored pictures) and the strong evidence of efficacy is vital. Teaching ICS inhaler technique, environmental control, and giving a written action plan are essential. Lack of initiation of ICS with appropriate patient education before discharge from the ED in patients with persistent asthma is common but unfortunately associated with continued poor patient outcomes.

Correct use of inhalation devices is one essential component of optimal management of asthma. Several longstanding controversies regarding specific steps to correct use of metered dose inhalers (MDI) include the lung volume when the MDI should be actuated. As a primary objective, literature was reviewed examining this one step in MDI use. Results from six of nine investigations support the need to gently exhale either to functional residual capacity (FRC) or residual volume (RV) before MDI actuation. Literature is also summarized regarding the need to exhale to FRC or RV before inhaling from MDI plus valved holding chambers or other extension devices and from dry powder inhalers. Numerous studies indicate that many patients as well as health care professionals either do not know or forget to exhale to RV or FRC before inhaling asthma medications. Both patients and health care professionals need education to help ensure correct use of MDI and other asthma inhalation devices, including instruction to first exhale gently to RV or FRC before inhaling the medication.

BACKGROUND: To determine the occurrence of hepatotoxicity associated with rifampin treatment of latent tuberculosis infection in patients from a public health tuberculosis clinic. METHODS: Evaluation of rifampin hepatotoxicity in adults aged >or=18 years from a database maintained from June 2001 to May 2007 in a public health department clinic. Rifampin 600 mg daily for 4 months was prescribed. Hepatotoxicity was defined as aspartate aminotransferase (AST) or alanine aminotransferase (ALT) levels more than 3 times the upper limit of normal (ULN) with symptoms or more than 5 times the ULN without symptoms. RESULTS: Rifampin therapy was initiated in 348 patients. Among 205 patients with evaluable data, 4 (1.95%, 95% confidence interval: 0%-4.33%) had AST or ALT levels >5 times the ULN (2 patients at 1 month and 2 patients at 3 months). Three of these patients had elevated AST/ALT at baseline; 1 had hepatitis C and 1 had an unconfirmed history of hepatitis. Adherence to clinic visits and prescribed treatment was poor. CONCLUSIONS: Rifampin hepatotoxicity associated with treatment of latent tuberculosis infection is rare. Our report suggests that hepatotoxicity is more likely in patients with baseline hepatic dysfunction and the need for increased vigilance in monitoring transaminases in these patients.

Undocumented patient information in the medical record (MR) is a barrier to providing high quality care. Inadequate documentation has recently been reported for two cardiovascular diseases. This study was designed to evaluate the documentation of asthma management in the MR to determine if it is consistent with the NIH asthma guidelines. We performed a retrospective chart review of patients (ages 18-49) admitted to the hospital with an ICD-9 code for a primary diagnosis of asthma between January 2004 and May 2007. Patients admitted with a hospitalization for >24 hours and had <10 pack per year smoking history were included. We assessed medication regimens, documentation of asthma education, asthma action plans, referrals, and exacerbating factors. There were 233 admissions for 144 unique patients analyzed. At discharge, 85% of patients lacked documentation of asthma education, 97% lacked documentation of a written asthma action plan being given, and 79% did not have referral to an asthma specialist. Respiratory infection was the most common factor associated with admission; 58% of admissions were lacking documentation of the exacerbating factor. Only 47% of patients were receiving inhaled corticosteroids (ICS) prior to admission; 25% of patients did not have ICS prescribed for maintenance therapy upon discharge. Documentation of asthma management, specifically asthma education in the MR, is insufficient and may reflect a deficiency in care. Additionally, an inadequate number of patients were receiving ICS for maintenance therapy. Based on these findings, mechanisms are needed to ensure appropriate documentation and optimal care.

Alcohol withdrawal syndrome (AWS) is a serious complication of abrupt alcohol cessation. Severe AWS can develop into delirium tremens (DT), which is potentially life-threatening. Lorazepam (LOR) and chlordiazepoxide (CDE) are mainstays of therapy for AWS. Current literature lacks studies comparing outcomes between the two drugs for patients who are not in a de-addiction ward specifically for withdrawal treatment. The primary objective of the study was to determine the incidence rate of DT between the groups. Of 2112 patients screened, 142 met inclusion criteria (LOR = 74, CDE = 68). Baseline characteristics were similar between groups. No significant difference in the primary outcome of DT development was observed (7% LOR, 9% CDE; p = 0.76). No significant differences in cumulative doses of scheduled LOR or CDE were observed (LOR 14.6 ± 8 mg, CDE 15.4 ± 12; p = 0.64). However, significant differences were found in the amount of "as needed" (PRN) LOR required for the two groups (LOR 3.2 ± 4 mg, CDE 6.6 ± 13 mg; p = 0.03) and the amount of scheduled plus PRN LOR required (LOR 17.7 ± 10 mg, CDE 21.9 ± 14 mg; p = 0.04). Doses are reported in LOR equivalents. There were no observed differences in duration of treatment (LOR 3.6 ± 1.3 days, CDE 3.9 ± 2.1 days; p = 0.3) or length of stay (LOR 5.28 ± 3.8 days, CDE 4.73 ± 4.2 days p = 0.4). No adverse events related to BZD were noted in either group. Hospital outcomes did not differ between the groups, but patients treated with CDE may require more adjuvant therapy to control symptoms of AWS. Both agents appear equally effective at preventing the development of DT in those patients admitted to general medicine wards.
