Despite a growing body of literature supporting the potential benefit of pharmacist‐managed warfarin therapy (PMWT), comprehensive reviews regarding this topic are still lacking. A systematic search of literature was done in Pubmed/Medline, Scopus, Google Scholar, and Cochrane Library from database inception to January 2014. Studies comparing PMWT with usual medical care (UMC) regarding the control of anticoagulation, bleeding and thromboembolic events, mortality, hospitalization, emergency department visit, cost, patients' satisfaction, and quality of life were included. Of 758 potential articles identified, 24 studies (4 randomized controlled trials [RCT] and 20 non‐RCT studies) with a population of 11 607 were included. Among non‐RCT studies, the percentage of time in the therapeutic range (72.1% vs 56.7%; P = .013), major bleeding events (0.6% vs 1.7%, P < .001), thromboembolic events (0.6% vs 2.9%; P < .001), hospitalization (3% vs 10%; P < .001), emergency department visits (7.9% vs 23.9%; P < .0001) significantly favored PMWT. The study supported PMWT regarding cost saving and patient satisfaction. The results showed that the PMWT model is superior to UMC in managing warfarin therapy based on observational studies. As well, it is comparable to UMC based on RCT studies.

These results support the importance of clinical pharmacists' participation in health care team rounds to improve the overall quality of medication therapy, enhance patient care and outcome and reduce drug costs to patients and society.

Background:Hypoglycemia is a common and the most important complication of intensive insulin therapy in critically ill patients. Because of hypoglycemia’s impact on the cardinal organs as a fuel, if untreated it could results in permanent brain damage and increased mortality.Objectives:In this study, we aim to evaluate the incidence of hypoglycemia, its risk factors, and its relationship with mortality in critically ill patients.Patients and Methods:Five hundred adult patients who admitted to an intensive care unit (ICU) were enrolled in this study. A program of glycemic control with a target of 100 - 140 mg/dL was instituted. We used the threshold of 150 mg/dL for septic patients, which were monitored by point of care devices for capillary blood measurement. We detected hypoglycemia with a blood sugar of less than 50 mg/dL and with the detection of each episode of hypoglycemia, blood glucose measurement was performed every 30 minutes.Results:Five hundred patients experienced at least one episode of hypoglycemia, almost always on the third day. Of 15 expired patients who had one hypoglycemia episode, the most common causes were multiple trauma and sepsis. Increases in the sequential organ failure assessment (SOFA) number augmented the hypoglycemia risk to 52% (P < 0.001). Moreover, in patients with acute kidney injury (AKI), the risk of hypoglycemia is 10 times greater than in those without AKI (RR: 10.3, CI: 3.16 - 33.6, P < 0.001). ICU admission blood sugar has a significant relationship with mortality (RR: 1.01, CI: 1.004 - 1.02, P < 0.006). Hypoglycemia increased the mortality rate twofold, but it was not significant (RR: 1.2, CI: 0.927 - 1.58, P = 0.221).Conclusions:Our results showed that the SOFA score, AKI, and hemoglobin A1c are the independent risk factors for the development of hypoglycemia and demonstrated that ICU admission blood glucose, Hba1c, and hypoglycemia increased the risk of death, but only ICU admission blood glucose is significantly related to increased mortality.

Despite the known role of vitamin D deficiency in development of thrombosis, no studies have evaluated the impact of treating of vitamin D deficiency on the markers of thrombosis. A pilot randomized clinical trial was done on 40 vitamin D-deficient patients with deep vein thrombosis (DVT) or pulmonary embolism (PE). The intervention group received an oral dose of 50,000 IU vitamin D every week for 8 weeks, followed by 1 pearl every 2 weeks for 4 weeks (a total of 3 months), while the control group did not receive vitamin D. Then, P-selectin and hs-CRP were measured at baseline and 1 and 3 months after the intervention. There was no significant decrease in hs-CRP in either group after 1 month (P = .955) or after 3 months (P = .525). Likewise, there was no significant decrease in P-selectin between the 2 groups after 1 month (P = .921) or 3 months (P = .795). The results indicated that treatment of vitamin D deficiency had no significant effect on hs-CRP or P-selectin after 3 months among DVT/PE patients. However, treatment of vitamin D deficiency in these patients resulted in the control of the international normalized ratio (INR) with the lower doses of warfarin. This observation is the first clinical report of enhancement of the anticoagulant effect of warfarin by the supplementing of vitamin D. Larger trials are needed to clearly show the effect of treating of vitamin D deficiency on thrombosis.

Background:Critically ill patients under mechanical ventilation require frequent suctioning of airway secretion. Closed suction permits suctioning without disconnection from ventilator; so it might decrease hypoxemia and infection rate.Objectives:This study aimed to evaluate the effect of closed tracheal suction system (CTSS) versus open tracheal suction system (OTSS).Patients and Methods:This is a prospective randomized study, which was carried on 100 patients in surgical Intensive Care Unit requiring mechanical ventilation for more than 48 hours from June 2012 to November 2013. In two groups, suction was performed based on the patients' need as well as physician's or nurses' decision on tracheal secretions. Patients randomly allocated into two groups (50 patients each): CTSS group and OTSS group. Patients were monitored for developing ventilator-associated pneumonia (VAP) during the study. Throat samples were taken on admission and two times per week from each patient. Tracheal samples were performed during endotracheal intubation, two times per week during mechanical ventilation and during extubation.Results:Drainage of subglottic secretions decreased the incidence of VAP (P < 0.05). Also type of the pharmacologic medicine for stress ulcer prophylaxis has significant effect on VAP incidence. Among the patients in OTSS and CTSS groups, 20% and 12% developed VAP, respectively. Use of CTSS compared with OTSS did not show statistically significant effect on VAP incidence in multivariate analysis; however, OR (odds ratio) tended to identify OTSS as an exposure factor for the development of VAP (OR = 1.92; CI = 0.45-8.30; = 0.38) compared with the CTSS. Higher levels of APACHE II score, sinusitis and tracheostomy put the patients at the risk of VAP. However, using heat and moisture exchanger (HME) instead of humidifier decreased this risk.Conclusions:Based on the results obtained from our study, impact of suctioning is similar between CTSS and OTSS regarding the occurrence of VAP. It seems that physicians must consider many factors such as duration of mechanical ventilation, comorbidities, oxygenation parameters, number of required suctioning, and the cost prior to using each type of tracheal suction system.
