Summary Reports of interventions to improve adherence to medical regimens in solid organ transplant recipients are scarce. A systematic review identified 12 intervention studies. These studies focused on renal, heart, and liver transplant recipients. Five reports used randomized controlled trial (RCT) designs. Sample sizes varied between 18 and 110 subjects. The interventions are difficult to evaluate and categorize because of brief descriptions of intervention details. Of the 12 studies identified in this review, only five studies found a statistically significant improvement in at least one medication‐adherence outcome with the intervention. In general, most included a combination of patient‐focused cognitive/educational, counseling/behavioral, and psychologic/affective dimensions. Eight studies intervened at the healthcare provider, healthcare setting or healthcare system level, but showed a limited improvement in adherence. No single intervention proved to be superior at increasing medication‐adherence in organ transplantation, but a combination of interventions in a team approach for the chronic disease management of organ transplant patients may be effective in a long‐term perspective. In conclusion, finding the most effective combination of interventions to enhance adherence is vital. Utilizing an RCT design and adhering to the CONSORT guidelines can lead to higher quality studies and possibly more effective intervention studies to enhance medication‐adherence.

Over 485,000 people in the United States have chronic kidney disease, a progressive kidney disease that may lead to hemodialysis. Hemodialysis involves a complex regimen of treatment, medication, fluid, and diet management. In 2005, over 312,000 patients were undergoing hemodialysis in the United States. Dialysis nonadherence rates range from 8.5% to 86%. Dialysis therapy treatment nonadherence, including treatment, medication, fluid, and diet nonadherence, significantly increases the risk of morbidity and mortality. The purpose of this paper is to systematically review randomized-controlled trial intervention studies designed to increase treatment, medication, fluid, and diet adherence in adult hemodialysis patients. A search of Cumulative Index of Nursing and Allied Health Literature (CINAHL) (1982 to May 2008), MEDLINE (1950 to May 2008), PsycINFO (1806 to May 2008), and all Evidence-Based Medicine (EBM) Reviews (Cochran DSR, ACP Journal Club, DARE, and CCTR) was conducted to identify randomized-controlled studies that tested the efficacy of interventions to improve adherence in adult hemodialysis patients. Eight randomized-controlled trials met criteria for inclusion. Six of the 8 studies found statistically significant improvement in adherence with the intervention. Of these 6 intervention studies, all studies had a cognitive component, with 3 studies utilizing cognitive/behavioral intervention strategies. Based on this systematic review, interventions utilizing a cognitive or cognitive/behavioral component appear to show the most promise for future study.

Background Quality of bowel preparation prior to colonoscopy is essential. Studies have shown a reduced volume of polyethylene glycol (PEG) with bisacodyl may improve visualization and tolerability, but results have varied. Therefore, a meta-analysis was performed to analyze the efficacy of a low-volume PEG bowel preparation with bisacodyl for bowel preparation prior to colonoscopy. Methods Multiple databases were searched (June 2012). Only randomized controlled trials in peer-reviewed journals on adult subjects comparing low-volume PEG (2 L) with bisacodyl versus 4 L PEG were included. Meta-analysis for the efficacy of low-volume PEG with bisacodyl and 4 L PEG were analyzed by calculating pooled estimates of number of satisfactory, excellent, and poor bowel preparations as well as adverse patient events (abdominal pain, nausea, vomiting, bloating). Results Six studies (N=1,540) met the inclusion criteria. No statistically significant differences were noted between low-volume PEG (2 L) with bisacodyl and 4 liters PEG for number of satisfactory (OR 0.86; 95% CI: 0.45-1.63, P=0.64), excellent (OR 1.08; 95% CI: 0.78-1.50, P=0.63), or poor bowel preparations (OR 0.68; 95% CI: 0.35-1.34, P=0.27). A statistically significant decrease in nausea (OR 0.57; 95% CI: 0.36-0.89, P=0.01), vomiting (OR 0.57; 95% CI: 0.40-0.81, P<0.01), and bloating (OR 0.65; 95% CI: 0.49-0.87, P<0.01) was noted for the low-volume PEG with bisacodyl as compared to 4 L PEG. No statistically significant differences were noted between the two groups for abdominal pain (P=0.62). Conclusion Low-volume PEG (2 L) with bisacodyl demonstrates less nausea, vomiting, and bloating without adversely affecting the bowel preparation.

Early tube feeding ≤3 hours after PEG placement has no significant differences to delayed or next-day feeding in respect to complications, death in ≤72 hours, or number of significant gastric residual volumes at day 1.

Early feeding < or = 4 h after PEG placement may represent a safe alternative to delayed or next-day feedings. Although an increase in significant gastric residual volumes at day 1 was noted, overall complications were not affected.
