Review Meta Analysis
Do hospital fall prevention programs work? A systematic review.
To analyze published hospital fall prevention programs to determine whether there is any effect on fall rates. To review the methodological quality of those programs and the range of interventions used. To provide directions for further research. ⋯ The pooled effect of about 25% reduction in the fall rate may be a result of intervention but may also be biased by studies that used historical controls not allowing for historical trends in the fall rate before and during the intervention. The randomized controlled trials apparent lack of effect might be due to a change in practice when patients and controls were in the same unit at the same time during a study. Studies did not analyze compliance with the intervention or opportunity costs resulting from the intervention. Research and clinical programs in hospital fall prevention should pay more attention to study design and the nature of interventions.

To review (1) the physiologic changes of aging that may lead to the need for a permanent pacemaker; (2) the current standard indications for pacemaker implantation as reported in expert guidelines; (3) newer investigational uses of pacemakers; (4) advances in pacemaker technology; and (5) cost-effectiveness of permanent pacing. ⋯ Permanent pacing is highly cost-effective, safe, and simple to perform. Pacemakers are implanted in patients with sinus node dysfunction, acquired (both native and postsurgical) atrioventricular block, some forms of neurally mediated syndromes, fascicular blocks, and, occasionally, for the prevention of supraventricular or ventricular tachyarrhythmias. Although pacemakers are implanted in individuals of all ages, they are most often utilized in older adults; it is estimated that 70 to 80% of all pacemakers are implanted in patients 65 years of age or older. This is attributable to an increase in abnormalities of impulse generation and conduction with advancing age. Dual chamber pacemakers that maintain synchrony between atria and ventricles are preferable in older patients because of the increased contribution of atrial contraction to ventricular filling in this age group. This theoretical advantage has been confirmed by prospective studies in limited patient subgroups.
