Comparing costs and cost-efficiency of platforms for micronutrient powder (MNP) delivery to children in rural Uganda.

Micronutrient powder (MNP) can reduce iron deficiency in young children, which has been well established in efficacy trials. However, the cost of different delivery platforms has not been determined. We calculated the cost and cost-efficiency of distributed MNP through community-based mechanisms and in health facilities in a primarily rural district in Uganda. An endline survey (n = 1072) identified reach and adherence. During the 9-month pilot, 37,458 (community platform) and 12,390 (facility platform) packets of MNP were distributed. Each packet consisted of 30 MNP sachets. In 2016, total costs were $277,082 (community platform, $0.24/sachet) and $221,568 (facility platform, $0.59/sachet). The cost per child reached was lower in the community platform ($53.24) than the facility platform ($65.97). The cost per child adhering to a protocol was $58.08 (community platform) and $72.69 (facility platform). The estimated cost of scaling up the community platform pilot to the district level over 3 years to cover approximately 17,890 children was $1.23 million (scale-up integrated into a partner agency program) to $1.62 million (government scale-up scenario). Unlike previous estimates, these included opportunity costs. Community-based MNP delivery costs were greater, yet more cost-efficient per child reached and adhering to protocol than facility-based delivery. However, total costs for untargeted MNP delivery under program settings are potentially prohibitive.

Efficacy and Cost-effectiveness of Topical Vancomycin Powder in Primary Cementless Total Hip Arthroplasty.

Topical vancomycin has been shown to effectively reduce infections after spinal surgery while remaining safe and cost-effective; however, there are few studies evaluating topical vancomycin in total hip arthroplasty. The authors hypothesized that the incidence of periprosthetic joint infection would decrease with the use of topical vancomycin in total hip arthroplasty and that topical vancomycin would be cost-effective. A retrospective patient chart review was performed to evaluate consecutive primary cementless total hip arthroplasties performed in the authors' hospital system between April 2015 and December 2016. Demographic data were collected. Periprosthetic joint infection was defined by Musculoskeletal Infection Society criteria. Statistical analysis included t test, Fisher's exact test, and logistic regression. The costs of vancomycin and postoperative infection were used to determine the absolute risk reduction (1/number needed to treat) threshold needed for topical vancomycin to be cost-effective. In this study, 309 patients (55.7%) undergoing total hip arthroplasty were treated with topical vancomycin, and 246 patients (44.3%) did not receive treatment. There were 2 infections in the vancomycin group (0.6% incidence), and 4 in the no vancomycin group (1.6% incidence). There was no statistical difference in infection rate between the 2 cohorts (P=.414). The absolute risk reduction was 0.98%, and the number needed to treat with topical vancomycin was 102 patients to prevent 1 periprosthetic joint infection. Topical vancomycin ($12 per vial) resulted in an expected cost savings of $904 per patient. Topical vancomycin is inexpensive and cost-effective. Although not statistically significant, the topical vancomycin group had a 60% lower incidence of infection. Further research regarding appropriate prophylactic topical and intravenous antibiotic use is needed prior to widespread adoption. [Orthopedics. 2019; 42(5):e430-e436.].

Preclinical and clinical assessment of inhaled levodopa for OFF episodes in Parkinson's disease.

Inhaled drugs offer advantages, such as rapid onset of action, but require formulations and delivery systems that reproducibly and conveniently administer the drug. CVT-301 is a powder formulation of levodopa delivered by a breath-actuated inhaler that has been developed for treating OFF episodes (motor fluctuations between doses of standard oral levodopa) in patients with Parkinson's disease (PD). We present preclinical, phase 1, and phase 2 results for CVT-301. In dogs insufflated with a levodopa powder, plasma levodopa peaked in all animals 2.5 min after administration; in contrast, in dogs dosed orally with levodopa plus carbidopa, plasma levodopa was not detected until 30 min after administration. In 18 healthy persons, comparisons between inhaled CVT-301 and oral carbidopa/levodopa showed analogous differences in pharmacokinetics. Among 24 PD patients inhaling CVT-301 as a single 50-mg dose during an OFF episode, 77% showed an increase in plasma levodopa (>400 ng/ml) within 10 min versus 27% for oral dosing with carbidopa/levodopa at a 25-mg/100-mg dose. Improvements in timed finger tapping and overall motor function (Part III of the Unified Parkinson's Disease Rating Scale) were seen 5 and 15 min after administration, the earliest assessment time points. For average and best change, the improvements were statistically significant compared to placebo. The most common adverse event was cough; all cough events were mild to moderate, occurred at the time of inhalation, resolved rapidly, and became less frequent after initial dosing. These results support further development of CVT-301 for better management of PD.

Demographic and socioeconomic correlates of powder cocaine and crack use among high school seniors in the United States.

OBJECTIVES: Rates of powder cocaine and crack use have fluctuated among adolescents over recent decades. Little attention has been paid to recent trends, particularly regarding differences between users of powder cocaine and crack-two forms of the substance that are commonly reported together as "cocaine" use, despite having different effects and rates of adverse outcomes. METHODS: We examined data from nationally representative samples of high school seniors who participated in the Monitoring the Future study during years 2005-2011 (weighted N = 65 717). RESULTS: Many demographic and socioeconomic variables were similarly correlated with lifetime use of powder cocaine and crack. Income of >$50/week from job increased the odds for use, and income of >$50/week from sources other than a job more than doubled the odds for use. High religiosity, high parent education, identifying as black, and residing with one or two parents reduced odds for use. Hispanic students were at higher odds for use of crack and females were at lower odds for using powder cocaine. Among cocaine users, residing with one or two parents lowered odds for using both forms, and more religious students and Hispanics were at higher odds for crack-only use. CONCLUSIONS: Those interested in preventing initiation and adverse consequences of cocaine use should take into account the overlapping, yet different risk profiles of powder cocaine and crack users when developing programming. This is particularly important when considering differences in legal consequences for these pharmacologically similar forms of cocaine.

Comparative effectiveness and cost-benefit analysis of local application of vancomycin powder in posterior spinal fusion for spine trauma: clinical article.

OBJECT: Surgical site infection (SSI) is a morbid complication with high cost in spine surgery. In this era of health care reforms, adjuvant therapies that not only improve quality but also decrease cost are considered of highest value. The authors introduced local application of vancomycin powder into their practice of posterior spinal fusion for spine trauma and undertook this study to determine the value and cost benefit of using vancomycin powder in surgical sites to prevent postoperative infections. METHODS: A retrospective review of 110 patients with traumatic spine injuries treated with instrumented posterior spine fusions over a 2-year period at a single institution was performed. One group (control group) received standard systemic prophylaxis only, whereas another (treatment group) received 1 g of locally applied vancomycin powder (spread over the surgical wound) in addition to systemic prophylaxis. Data were collected on patient demographic characteristics, clinical variables, surgical variables, and 90-day morbidity. Incidence of infection was the primary outcome evaluated, and billing records were reviewed to determine total infection-related medical cost (cost of reoperation/wound debridement, medications, and diagnostic tests). The payer's cost was estimated to be 70% of the total billing cost. RESULTS: A total of 110 patients were included in the study. The control (n = 54) and treatment groups (n = 56) were similar at baseline. Use of vancomycin powder led to significant reduction in infection rate (13% infection rate in the control group vs 0% in the treatment group, p = 0.02). There were no adverse effects noted from the use of vancomycin powder. The total mean cost of treating postoperative infection per patient was $33,705. Use of vancomycin powder led to a cost savings of $438,165 per 100 posterior spinal fusions performed for traumatic injuries. CONCLUSIONS: The use of adjuvant vancomycin powder was associated with a significant reduction in the incidence of postoperative infection as well as infection-related medical cost. These findings suggest that use of adjuvant vancomycin powder in high-risk patients undergoing spinal fusion is a cost-saving option for preventing postoperative infections, as it can lead to cost-savings of $438,165 per 100 spinal fusions performed.

Tiotropium bromide inhalation powder: a review of its use in the management of chronic obstructive pulmonary disease.

The anticholinergic agent tiotropium bromide (Spiriva®) is a long-acting bronchodilator that is indicated for the treatment of chronic obstructive pulmonary disease (COPD). This article reviews the clinical efficacy and tolerability of tiotropium bromide inhalation powder, administered using the HandiHaler® device, in patients with COPD, as well as reviewing its pharmacological properties and the results of pharmacoeconomic analyses. Shorter-term placebo-controlled trials in patients with COPD demonstrated significantly higher trough forced expiratory volume in 1 second (FEV(1)) responses with tiotropium bromide than with placebo, confirming it has a duration of action of ≥24 hours and is suitable for once-daily administration. Lung function improved to a greater extent with tiotropium bromide than with ipratropium bromide or, in most instances, salmeterol. Indacaterol was shown to be noninferior to tiotropium bromide in terms of the trough FEV(1) response. The large, 4-year UPLIFT® trial did not show a significant reduction in the annual rate of decline in FEV(1) with tiotropium bromide versus placebo in patients with COPD, although subgroup analyses demonstrated a significantly lower rate of decline with tiotropium bromide than with placebo in some patient groups (e.g. patients with moderate COPD, patients aged ≥50 years, patients not receiving maintenance therapy at baseline). Tiotropium bromide prevented exacerbations in patients with COPD, with a significantly lower exacerbation rate and a significantly longer time to first exacerbation seen with tiotropium bromide than with placebo or salmeterol. Exacerbation rates did not significantly differ between patients receiving tiotropium bromide and those receiving salmeterol/fluticasone propionate. Tiotropium bromide also had beneficial effects on health-related quality of life (HR-QOL) and other endpoints, such as dyspnoea and rescue medication use. Combination therapy with tiotropium bromide plus formoterol with or without budesonide improved lung function to a significantly greater extent than tiotropium bromide alone in patients with COPD. In addition, exacerbation rates were lower and HR-QOL was improved with tiotropium bromide plus budesonide/formoterol versus tiotropium bromide alone. Although the addition of salmeterol/fluticasone propionate to tiotropium bromide did not reduce the COPD exacerbation rate, it did improve lung function and HR-QOL. Tiotropium bromide inhalation powder is generally well tolerated in patients with COPD, with anticholinergic adverse events (e.g. dry mouth, constipation, gastrointestinal obstruction, dysuria) among the most commonly reported adverse events. The UPLIFT® trial showed no significant difference between tiotropium bromide and placebo recipients in the risk of stroke, and the risk of serious cardiac adverse events (including congestive heart failure and myocardial infarction) was significantly lower with tiotropium bromide than with placebo. The absence of a detrimental effect on cardiovascular outcomes was supported by the results of a meta-analysis and pooled analyses. In addition, on-treatment mortality was lower with tiotropium bromide than with placebo in the UPLIFT® trial. Pooled analyses showed significantly lower cardiovascular mortality with tiotropium bromide than with placebo, with a meta-analysis demonstrating no significant difference between patients receiving tiotropium bromide and controls in cardiovascular mortality. Results of modelled pharmacoeconomic analyses conducted from a healthcare payer perspective in several developed countries suggest that tiotropium bromide is a cost-effective option in patients with COPD. In conclusion, tiotropium bromide inhalation powder is a useful option for the maintenance treatment of patients with COPD.

Equivalence of a single saline nebulised dose of formoterol powder vs three doses of nebulised Albuterol every twenty minutes in acute asthma in children: a suitable cost effective approach for developing nations.

BACKGROUND: An increase in asthma prevalence is reported from developed as well as developing nations, with rising costs from acute asthma and great expenditures to health care systems. Venezuela's Ministry of Health ambulatory facilities care for 80 % or more of a mostly urban and impoverished population of 26 million inhabitants, registering close to a million acute asthma visits per year; a nebulised fixed fenoterol-ipratropium bromide combination (Bero-dual, Boehringer-Ingelheim) in repeated dosing is the standard treatment. OBJECTIVES: to simplify acute asthma care and management in a cost effective manner employing Formoterol Fumarate powder, a long acting beta agonist with immediate bronchodilator effects. METHODOLOGY: Fifty acute asthmatic children (5-12 years old) were randomly assigned (25 patients in each group) to receive either a nebulised single dose (US $1.35) of two 12 microg Formoterol Fumarate capsules (Foradil 12 microg/cap, Novartis Pharma AG, Basel, Switzerland) diluted in 2.5 ml of sterile saline solution; or 3 doses of Albuterol (US $ 6.73) every twenty minutes for one hour (Glaxo Smith Kline Albuterol ampoules, 2.5 mg/2.5 ml, at a dose of 0.15 mg/kg/dose, maximum dose 2.5 mg). Symptoms score, oxygen saturation and lung function testing were recorded before and one hour after commencing treatments. RESULTS: Both groups improved significantly on all parameters, except for FEV(1) in the Albuterol group. CONCLUSIONS: Single dose nebulised Formoterol Fumarate (dry powder) in sterile saline solution, as depicted in this trial, is equivalent to three doses of Albuterol every twenty minutes for one hour in acute asthma in children, simplifying acute care management and at one fifth of medication costs. A pursuit of simpler and more cost effective approaches is found wanting in developing nations with depressed economies and unique cultural and socio-medical contexts; also, in countries where pharmaco-economics orients quality of health policies, novel approaches like this are worth exploring.

Albumin-bound paclitaxel (Abraxane) for advanced breast cancer.

A new formulation that should be safer and easier to administer than Taxol.

Latest advances in nasal drug-delivery technology.

Nasal delivery devices are not only limited to local medical therapy. The nasal route is an alternative to invasive or oral drug administration. The penetration of bioactive molecules through the nasal mucosa has been shown to achieve good bioavailability, and nasal sprays offer patients greater convenience. This article reviews some of the latest devices for liquid and dry-powder formulations, including preservative-free systems, and the business benefits they offer.

Assessment of the inhalation technique in outpatients with asthma or chronic obstructive pulmonary disease using a metered-dose inhaler or dry powder device.

Inhaled medication is commonly prescribed for the treatment of asthma and chronic obstructive pulmonary disease (COPD), but is often not properly used by patients. A total of 316 patients suffering from asthma or COPD took part in a study that evaluated how patients utilized their metered-dose inhaler (MDI) or dry powder inhaler, using a standardized inhaler checklist. Two hundred eighty-one patients (88.9%) made at least one mistake in the inhalation technique. The mistakes were classified into skill and nonskill mistakes. Two hundred patients made one or more skill mistakes and 81 patients only made one or more nonskill mistakes. The most common skill error was "not continuing to inhale slowly after activation of the canister" (69.6%). The nonskill item most patients had difficulties with was "exhale before the inhalation" (65.8%). Patients who used an MDI made significantly fewer nonskill mistakes than patients using a dry powder device. Older patients had more difficulty with the correct use of the inhaler than younger patients. There was no difference in errors between men and women. In this patient sample, most patients failed to use their inhaler correctly. Regular instructions and checkups of inhalation technique are the responsibility of the physician and should be a standard and routine procedure.
