Feasibility of delivering survivorship care via lay health educators: A pilot randomized controlled trial among rural cancer survivors.

PURPOSE: We tested the feasibility of survivorship care plan (SCP) delivery with/without a lay health educator (LHE) telephone-delivered information session among rural cancer survivors, and their effects on health-related self-efficacy and knowledge of cancer history. METHODS: Randomized trial of cancer survivors from 3 rural oncology clinics featuring either SCP alone (control) or SCP plus LHE-delivered information session (intervention). Participants completed a questionnaire on health-related self-efficacy and knowledge of cancer-specific medical history. Responses were compared to medical records for accuracy. SCPs were then mailed to participants. Approximately 5 months later, participants completed a follow-up questionnaire. A subset of participants took part in subsequent qualitative interviews about their study experience. FINDINGS: Of 301 survivors approached, 72 (23.9%) were randomized (mean age 66.4 years; 3.1 years from diagnosis; 62.5% female), and 65 (90.3%) completed the study. Global mental and physical health or self-efficacy scores did not change significantly from baseline to follow-up for either group. In exploratory analyses, self-efficacy increased in participants with inadequate/marginal health literacy in the intervention arm (+0.7, 95% CI = 0.1-1.2; P = .01). Accuracy of knowledge did not improve but was high at baseline (mean 76.0±14.5%). 60.1% and 48.4% of control and intervention participants, respectively, found SCPs definitely/somewhat useful. Qualitative data (n = 20) suggested that SCPs were helpful to patients when primary and oncology care were less integrated. CONCLUSIONS: An LHE-delivered informational session was feasible but had limited benefit to rural cancer survivors versus delivery of SCP alone but may be of benefit to patients with low health literacy or with less integrated care.

Recent-Onset Altered Mental Status: Evaluation and Management.

Potential precipitating factors for the recent onset of altered mental status (AMS) include primary central nervous system insults, systemic infections, metabolic disturbances, toxin exposure, medications, chronic systemic diseases, and psychiatric conditions. Delirium is also an important manifestation of AMS, especially in older people who are hospitalized. Clinicians should identify and treat reversible causes of the AMS, some of which require urgent intervention to minimize morbidity and mortality. A history and physical examination guide diagnostic testing. Laboratory testing, chest radiography, and electrocardiography help diagnose infections, metabolic disturbances, toxins, and systemic conditions. Neuroimaging with computed tomography or magnetic resonance imaging should be performed when the initial evaluation does not identify a cause or raises concern for intracranial pathology. Lumbar puncture and electroencephalography are also important diagnostic tests in the evaluation of AMS. Patients at increased risk of AMS benefit from preventive measures. The underlying etiology determines the definitive treatment. When intervention is needed to control patient behaviors that threaten themselves or others, nonpharmacologic interventions are preferred to medications. Physical restraints should rarely be used and only for the shortest time possible. Medications should be used only when nonpharmacologic treatments are ineffective.

Examining the Healthcare Administrator's Perspective on "Teamness" in Primary Care.

EXECUTIVE SUMMARY: Team-based care has been identified as an important element of effective primary care practice. While there is a growing body of literature supporting the value of team-based care, research on best practices in team-based care has suffered from the lack of a widely accepted framework with common definitions. We used qualitative interviews to explore healthcare administrators' perspectives regarding team-based care descriptions, their decisions regarding composition of a team, and how they identify characteristics of a well-functioning team. Interviewees discussed six broad themes: (1) definitions of team-based care, (2) team structure and roles, (3) team goals, (4) monitoring team effectiveness, (5) challenges to implementing team-based care, and (6) the influence of healthcare policy on team-based care. The study findings can be used to identify further ways to assess the notion of "teamness."

Crohn's Disease: Diagnosis and Management.

Crohn's disease is a chronic inflammatory condition that affects the gastrointestinal tract. It can cause lesions from mouth to anus and may result in extraintestinal complications. The prevalence of Crohn's disease is increasing in adults and children. Genetic predispositions to Crohn's disease have been identified, and specific environmental factors have been associated with its development. Common presenting symptoms include diarrhea, abdominal pain, rectal bleeding, fever, weight loss, and fatigue. Physical examination should identify unstable patients requiring immediate care, include an anorectal examination, and look for extraintestinal complications. Initial laboratory evaluation identifies inflammation and screens for alternative diagnoses. Measurement of fecal calprotectin has value to rule out disease in adults and children. Endoscopy and cross-sectional imaging are used to confirm the diagnosis and determine the extent of disease. Treatment decisions are guided by disease severity and risk of poor outcomes. Patients commonly receive corticosteroids to treat symptom flare-ups. Patients with higher-risk disease are given biologics, with or without immunomodulators, to induce and maintain remission. For children, enteral nutrition is an option for induction therapy. All patients with Crohn's disease should be counseled on smoking avoidance or cessation. Patients with Crohn's disease are at increased risk of cancer, osteoporosis, anemia, nutritional deficiencies, depression, infection, and thrombotic events. Maximizing prevention measures is essential in caring for these patients.

Practical selection of antiemetics in the ambulatory setting.

Nausea and vomiting are mediated primarily by three neurotransmitter pathways: visceral stimulation releases dopamine and serotonin; vestibular and central nervous system activation release histamine and acetylcholine; and chemoreceptor trigger zone activation releases dopamine and serotonin. Clinicians can improve the effectiveness and cost-effectiveness of treatments by targeting the appropriate pathways. Antihistamines and anticholinergics are most effective in patients with vestibular-mediated nausea secondary to vertigo. Serotonin antagonists block serotonin in the intestines and chemoreceptor trigger zone, and are most effective for treating gastroenteritis. Dopamine antagonists block dopamine in the intestines and chemoreceptor trigger zone; indications for these agents are similar to those for serotonin antagonists. For treatment of mild pregnancy-induced nausea, pyridoxine with or without doxylamine is recommended, and ginger may also be effective. In patients with migraine headache-associated nausea, metoclopramide improves response to oral anti-migraine agents. Ondansetron reduces nausea and vomiting in children with acute gastroenteritis and in women with hyperemesis gravidarum.

The role of besifloxacin in the treatment of bacterial conjunctivitis.

OBJECTIVE: To evaluate the role of besifloxacin in bacterial conjunctivitis treatment. DATA SOURCES: Searches were made on MEDLINE/PubMed and EMBASE (January 2007 to January 2014) using the terms besifloxacin and Besivance. References from these publications were reviewed for additional resources. Additional information was collected from Bausch & Lomb, the manufacturer of Besivance; www.clinicaltrials.gov; and American Academy of Ophthalmology. STUDY SELECTION AND DATA EXTRACTION: English-language documents were reviewed for pharmacology, pharmacokinetics, efficacy, and safety, with priority on clinical trials. DATA SYNTHESIS: Three large randomized controlled clinical trials established the safety and efficacy of besifloxacin ophthalmic suspension 0.6% compared with placebo or active comparator (moxifloxacin ophthalmic solution 0.5%) given 3 times a day for 5 days for acute bacterial conjunctivitis (BC) treatment. Compared with placebo, besifloxacin had clinically superior bacterial eradication rates and was noninferior to moxifloxacin. Besifloxacin was compared with placebo in 2 randomized, placebo-controlled trials, dosed twice a day for 3 days. Superior efficacy was seen compared with placebo, which supports the shorter dosing schedule. Ophthalmic besifloxacin is well tolerated; the most common adverse effect (conjunctival redness) occurred in 2% of patients. Adverse effects in 1% to 2% of patients included blurred vision, eye pain, eye irritation, eye pruritus, and headache. CONCLUSION: Besifloxacin 0.6% ophthalmic suspension 3 times a day for 5 days is safe and effective for BC. Twice-a-day dosing for 3 days was also effective-a simplified regimen compared with other fluoroquinolones. Disadvantages include price and lack of a generic. Further evaluation is needed to evaluate comparative efficacy among other ocular fluoroquinolones and unlabeled uses.

Alcaftadine for the prevention of itching associated with allergic conjunctivitis.

OBJECTIVE: To evaluate the safety and efficacy of alcaftadine for the prevention of itching associated with allergic conjunctivitis. DATA SOURCES: A medical literature search was conducted in MEDLINE/PubMed (2006-February 2012) and EMBASE (2006-February 2012) using the search terms alcaftadine and Lastacaft. References from these publications were reviewed for additional resources. Additional information was collected from Web sites of the US government (http://www.clinicaltrials.gov, http://www.fda.gov) and of Allergan Inc., the manufacturer of Lastacaft (http://www.lastacaft.com). STUDY SELECTION AND DATA EXTRACTION: All identified articles and publications in English were reviewed for pharmacology, pharmacokinetics, efficacy, and safety data. Priority was placed on clinical trials. DATA SYNTHESIS: Two published clinical trials evaluated the efficacy of alcaftadine in the prevention of ocular itching and conjunctival redness associated with allergic conjunctivitis. One trial compared alcaftadine to placebo, and another trial compared alcaftadine to placebo and olopatadine HCl to placebo. Both studies showed superior efficacy, both clinically and statistically, in the prevention of ocular itching associated with allergic conjunctivitis compared to placebo. Although conjunctival redness was evaluated in the 2 trials, neither trial demonstrated both clinical and statistical significance. Both trials demonstrated a rapid onset of action of less than 15 minutes, as well as a duration of action greater than 16 hours, which supports the use of once-daily administration. Overall, alcaftadine was well tolerated, and common adverse effects, reported in less than 4% of patients, included ocular irritation, pruritus, erythema, and stinging or burning upon instillation. Ocular adverse effects were typically mild in severity and self-limiting. CONCLUSIONS: Alcaftadine is a safe and effective option for the prevention of ocular itching associated with allergic conjunctivitis, is dosed once daily, and is competitively priced among prescription medications for allergic conjunctivitis. Additional studies are needed to further evaluate the comparative efficacy among ocular antihistamine/mast cell stabilizing medications.
