Numerous factors contribute to the medication errors that kill up to 98,000 patients each year. Unnecessarily high dosages can result in increased side effects with only a small therapeutic benefit, especially in elderly patients. Lack of patient information-such as a history of allergies or adverse drug reactions-is another cause of error and injury. Communication failures include the use of ambiguous abbreviations, misinterpretation of verbal orders, and lack of timely response to a patient's medication-related symptoms. Dosing errors are common in children because of variability in dosage expressions in drug references. Remedies for prescribing errors are described in detail here.

Treatment of fibromyalgia syndrome (FMS) is a challenge. However, most patients benefit from appropriate management. Essential to treatment are a physician's positive and empathetic attitude, continuous psychological support, patient education, patience, and a willingness to guide patients to do their part in management. Other important aspects involve addressing aggravating factors (eg, poor sleep, physical deconditioning, emotional distress) and employing various nonpharmacologic modalities (eg, regular physical exercise) and pharmacologic therapies. Drug treatment includes use of tricyclic medications alone or in combination with a selective serotonin reuptake inhibitor, and other centrally acting medications. Tender point injection is useful. It is important to individualize treatment. Management of FMS is both a science and an art.

Influenza:

ABSTRACT: When influenza is present in the community, clinical symptoms are as accurate as rapid point-of-care tests for making the diagnosis; in this setting, the combination of cough and fever (temperature, 37.7°C [100°F] or higher) of acute onset has a positive predictive value of 77% to 79%. Accurate diagnosis ensures timely administration of antiviral agents and prevents unnecessary antibiotic use. In elderly persons, vaccination reduces illness severity, incidence of complications, and mortality. An intranasal vaccine is a new option for persons aged 5 to 49 years who are at risk for complications and refuse injection. Chemoprophylaxis with amantadine, rimantadine, or a neuraminidase inhibitor is a useful adjunct to vaccination in certain groups, such as nursing-home residents. Antiviral therapy started within 24 to 48 hours of symptom onset can reduce the duration of illness by 1 to 1.5 days and ameliorate symptoms in patients with uncomplicated influenza. However, treatment is expensive and does not prevent complications.
