Adverse drug events occur often in hospitals. They can be prevented to a large extent by minimizing the human errors of prescription writing. To evaluate the efficacy of a computerized prescription order entry (CPOE) system with the help of ancillary support in minimizing prescription errors. ⋯ Involvement of the pharmacist in reviewing the prescription and alerting the physician has minimized prescription errors to a great degree in our hospital setting. The incidence of prescription errors before the CPOE has been reported to range from 3 to 99 per 1000 prescriptions. The disparity could be due to the definition of medical errors, which has changed over the years, and also number of prescriptions included in the study and the study design.

The authors retrospectively reviewed their experience with nitric oxide (NO) in a pediatric ICU. Given its cost ($3000/d), ongoing evaluations are required to ensure its effective use and avoid inappropriate applications. NO use included 4 categories: (1) hypoxemic respiratory failure, (2) pulmonary hypertension following surgery for congenital heart disease (CHD), (3) intraoperatively for surgical procedures such BT shunt placement or 1-lung ventilation, and (4) during ECMO. ⋯ The survival of responders was 9 of 9 versus 1 of 4 for nonresponders (P = 0.014). No significant adverse effects requiring therapy other than decreasing the inhaled NO concentration were noted. Potential interventions and practices to limit the unwarranted use of this costly agent are discussed.

We investigated the impact of kinetic beds on the incidence of atelectasis in mechanically ventilated patients in an intensive care unit (ICU). All bronchoscopies performed for atelectasis on mechanically ventilated patients between July 2000 and June 2001 and between July 2002 and June 2003 were reviewed. On July 26, 2001, 50 kinetic beds, 20 continuous lateral rotation therapy modules, and 20 percussion and vibration modules were introduced to our institution. ⋯ Of the 3065 ICU admissions between July 2002 and June 2003, 83 patients developed atelectasis while being mechanically ventilated. Of these, 48 (58%) patients had left-sided atelectasis, 30 (36%) had right-sided atelectasis, and 5 (6%) had bilateral atelectasis. There was no decrease in the incidence of atelectasis in mechanically ventilated patients at our institution after the introduction of kinetic beds and vibration, percussion, and rotation modules despite their widespread availability.

Randomized Controlled Trial Multicenter Study Comparative Study
A double-blind, controlled, multicenter, randomized study comparing the antihypertensive effectiveness and tolerance of a daily dose of two nifedipine formulations: nifedipine microgranules versus nifedipine osmotic pump.
Controlled clinical studies have clearly established the advantages of blood pressure (BP) reduction. However, optimal control of BP in the population is still not adequate. Monotherapy is ineffective in the majority of hypertensive patients, and multidrug therapy increases costs. ⋯ Target BP was reached in more than 70% of patients receiving monotherapy with either formulation. Both formulations were tolerated well.

Despite progress in recent years in the prevention, detection, and treatment of high blood pressure (BP), hypertension remains an important public health challenge. Hypertension affects approximately 1 billion individuals worldwide. High BP is associated with an increased risk of mortality and morbidity from stroke, coronary heart disease, congestive heart failure, and end-stage renal disease; it also has a negative impact on the quality of life. ⋯ DNA testing for genetic polymorphism and determining the genotype of a patient may predict response to a certain class of antihypertensive agent and thus optimize therapy in individual patients. In this regard, there are some studies that report the effectiveness of antihypertensive therapy based upon the genotype of selected patients. Treatment of human hypertension with vaccines is feasible but is not likely to be available in the near future.
