Introduction and Aim:Medication errors as a serious problem in world and one of the most common medical errors that threaten patient safety and may lead to even death of them. The purpose of this study was to investigate the causes of medication errors and strategies to prevention of them from nurses and nursing student viewpoint.Materials & Methods:This cross-sectional descriptive study was conducted on 327 nursing staff of khatam-al-anbia hospital and 62 intern nursing students in nursing and midwifery school of Zahedan, Iran, enrolled through the availability sampling in 2015. The data were collected by the valid and reliable questionnaire. To analyze the data, descriptive statistics, T-test and ANOVA were applied by use of SPSS16 software.Findings:The results showed that the most common causes of medications errors in nursing were tiredness due increased workload (97.8%), and in nursing students were drug calculation, (77.4%). The most important way for prevention in nurses and nursing student opinion, was reducing the work pressure by increasing the personnel, proportional to the number and condition of patients and also creating a unit as medication calculation. Also there was a significant relationship between the type of ward and the mean of medication errors in two groups.Conclusion:Based on the results it is recommended that nurse-managers resolve the human resources problem, provide workshops and in-service education about preparing medications, side-effects of drugs and pharmacological knowledge. Using electronic medications cards is a measure which reduces medications errors.
Diabetic foot ulcer is one of the most devastating complications of uncontrolled diabetes. Although there have been advances in the management of diabetic foot ulcers, still diabetic foot ulcers are a major cause of many amputations in diabetic patients. Teucrium polium ( T. polium) is widely used by folk medicine practitioners in Iran for the treatment of diabetic ulcers. The present study was designed to evaluate the safety and efficacy of topical T. polium ointment besides the standard treatment in diabetic foot ulcers. A total of 70 diabetic patients with foot ulcers grade 1 or 2 according to Wagner's scale were enrolled in this study. Patients were randomly divided into two groups. Patients in both groups received standard treatment for diabetic foot ulcers. In addition, group 1 received topical T. polium ointment, and group 2 received topical placebo ointment for 4 weeks. The T. polium and placebo ointments were rubbed twice daily two hours before the conventional dressing. The ulcer size, healing time, and laboratory tests were measured in both groups at baseline and end of the study after 4 weeks. Twenty-nine patients remained in the T. polium group and 26 in the placebo group until the end of the study. The mean surface area of ulcers was 3.52 ± 1.47 and 3.21 ± 1.67 cm2 in T. polium group and placebo group respectively at baseline which decrease to .717 ± .19 and 1.63 ± .72 cm2 respectively at the endpoint. The mean ulcer surface area was significantly lower in T. polium compared with the placebo group ( p < .0001) at end of the study. Also, the number of patients that completely recovered in the T. polium group was significantly higher than the placebo group ( p < .001) at the end of the study. The addition of topical T. polium ointment to standard treatment significantly improves the healing time of diabetic non-infected foot ulcers.
Diabetic foot ulcer is one of the major complications among diabetic patients. Several studies have shown that the extract of Teucrium polium (T. polium) is effective in the treatment of diabetic and non-diabetic wounds, as well as burn wounds. The aim of current study was to assess the wound healing activity of T. polium extract ointment in diabetic rats. Sixty-four male Wistar rats were induced diabetes with alloxan injection (125 mg/kg) and surgical wound induced. The rats were divided into 8 groups of eight rats each: control group, eucerin group, phenytoin group, 2%, 3%, 4%, 5% and 10% T. polium groups. The ointment was dressed on the wound twice a day. The process of wound healing was screened by macroscopy and digitalization on days 14 and 21 and until complete wound healing. There was no infection in the wounds of rats in any groups. The process of wounds healing of the 2%, 3%, 4%, 5%, and 10% T. polium ointments, with phenytoin ointment and base ointment (eucerin) on day 14 and 21, showed that the significant difference between the treatment groups with 4% (P = 0.003), 5% (P = 0.001), 10% (P = 0.001) T. polium ointment and phenytoin ointment group (P = 0.001) compared to eucerin group. The results of this study showed that T. polium extract ointment with a 10% ointment accelerates the wound healing process in diabetic rats and is comparable to the phenytoin group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
