It is a multidisciplinary process, which begins with the doctor’s prescription, followed by review and provision by a pharmacist, and ends with preparation and administration by a nurse. Several studies have highlighted a high medication incident rate at several healthcare institutions.Methods: Our study design was exploratory and evaluative and used methodological triangulation. Sample size was of two types. First, a convenient sample of 1000 medication dosages to estimate the medication error (95% CI). We took another sample from subjects involved in medication usage processes such as physicians, nurses, pharmacists, and patients. Two sets of instruments were designed via extensive literature review: a medication tracking error form and a focus group interview questionnaire.Results: Our study findings revealed 100% compliance with a computerized physician order entry (CPOE) system by physicians, nurses, and pharmacists. The main error rate was 5.5% and pharmacists contributed an higher error rate of 2.6% followed by nurses (1.1%) and physicians (1%). Major areas for improvement in error rates were identified: delay in medication delivery, lab results reviewed electronically before prescription, dispension, and administration.Keywords: medication error rate, associate error rate, physician, nurse, pharmacis

Association Between Appendectomy and Clostridium difficile Infection

BackgroundRecent theory proposes that the appendix functions as a reservoir for commensal bacteria, and serves to re-inoculate the colon with normal flora in the event of pathogen exposure or purging of intestinal flora. If true, we reasoned that flora from a normal appendix could provide protection against Clostridium difficile. We conducted this investigation to examine the protective effect of an intact appendix and test the hypothesis that prior appendectomy will be more common among patients with a positive test for C. difficile as compared with patients who test negative.MethodsWe contacted patients who had undergone C. difficile testing and asked them whether or not they had a prior appendectomy. Using their responses and results from Toxin A & B EIA tests, we calculated the difference in appendectomy rates between those who tested positive for C. difficile, and those who tested negative. We considered a positive 15% absolute difference to represent a significant increase in appendectomy rate.ResultsWe enrolled 257 patients. Among the 136 who tested positive for C. difficile, 27 (19.9%) had prior appendectomies, while among 121 patients testing negative for C. difficile, 38 (31.4%) had prior appendectomies, yielding a difference in appendectomy rates of -11.6% (95% Confidence Interval: -21.6% to -0.9%).ConclusionsThe rate of prior appendectomy was actually lower among patients with a positive C. difficile test as compared to those with a negative test. Conversely, patients who tested positive for C. difficile were more likely to have an intact appendix than those who tested negative. These results suggest that rather than being protective, an intact appendix appears to promote C. difficile acquisition, carriage, and disease.KeywordsClostridium difficile; Appendix; Appendectomy; Microbial reservoir; Infection

False-negative HIV tests using oral fluid tests in children taking antiretroviral therapy from Harare, Zimbabwe.

INTRODUCTION: Rapid diagnostic tests (RDT) for HIV infection have high sensitivity and specificity, but in the setting of longstanding antiretroviral therapy (ART), can give false results that can lead to misinterpretation, confusion and inadequate management. The objective of this study was to evaluate the proportion of falsely negative results of a RDT performed on oral fluid in HIV-infected children on longstanding ART. METHODS: One hundred and twenty-nine children with known HIV infection and receiving ART were recruited from the HIV Clinic at the Harare Central Hospital, Zimbabwe. HIV testing was performed on oral fluid and on finger-stick blood. RESULTS AND DISCUSSION: Children included in the study had a median age of 12 years (IQR 10-14) and 67 (51.9%) were female. Median age at HIV diagnosis was 5 years (IQR 3-6) and the median time on ART was 6.3 years (IQR 4.3-8.1). The oral fluid test was negative in 11 (8.5%) patients and indeterminate in 2 (1.6%). Finger-stick blood test was negative in 1 patient. Patients with a negative oral fluid test had a higher CD4 cell count (967 vs. 723 cells/mm3, p = 0.016) and a longer time on ART (8.5 vs. 6 years, p = 0.016). CONCLUSIONS: This study found that a substantial proportion of false-negative HIV test results in children on longstanding ART when using an oral fluid test. This could lead to misinterpretation of HIV test results and in the false perception of cure or delayed diagnosis

An observational study on the expression levels of MDM2 and MDMX proteins, and associated effects on P53 in a series of human liposarcomas

Background: Inactivation of wild type P53 by its main cellular inhibitors (MDM2 and MDMX) is a well recognised feature of tumour formation in liposarcomas. MDM2 over-expression has been detected in approximately 80% of liposarcomas but only limited information is available about MDMX over-expression. To date, we are not aware of any study that has described the patterns of MDM2 and MDMX co-expression in liposarcomas. Such information has become more pertinent as various novel MDM2 and/or MDMX single and dual affinity antagonist compounds are emerging as an alternative approach for potential targeted therapeutic strategies. Methods. We analysed a case series of 61 fully characterized liposarcomas of various sub-types by immunohistochemistry, to assess the expression levels of P53, MDM2 and MDMX, simultaneously. P53 sequencing was performed in all cases that expressed P53 protein in 10% or more of cells to rule out mutation-related over-expression. Results: 50 cases over-expressed MDM2 and 42 of these co-expressed MDMX at varying relative levels. The relative expression levels of the two proteins with respect to each other were subtype-dependent. This apparently affected the detected levels of P53 directly in two distinct patterns. Diminished levels of P53 were observed when MDM2 was significantly higher in relation to MDMX, suggesting a dominant role for MDM2 in the degradation of P53. Higher levels of P53 were noted with increasing MDMX levels suggesting an interaction between MDM2 and MDMX that resulted in a reduced efficiency of MDM2 in degrading P53. Of the 26 cases of liposarcoma with elevated P53 expression, 5 were found to have a somatic mutation in the P53 gene. Conclusions: The results suggest that complex dynamic interactions between MDM2 and MDMX proteins may directly affect the cellular levels of P53. This therefore suggests that careful characterization of both these markers will be necessary in tumours when considering in vivo evaluation of novel blocker compounds for MDM proteins, as a therapeutic strategy to restore wild type P53 function

Registered nurses perception of work satisfaction at a Tertiary Care University Hospital

Hospitals are facing serious challenges to provide high quality care with current nursing shortages. Nursing shortages are of major concern for Nursing Management, clinicians and administrators as they lead to impact on quality of care. Under-stressed, frustrated and demoralized nurses give rise to concern for hospital Nursing Management in providing quality care according to set standards. A descriptive qualitative research design was used to explore the registered nurses\u27 perceptions regarding the high turnover rates among nurses at a Tertiary Care University Hospital. Data was collected from nurses working at various speciality areas, which were: Critical Care, Medical and Surgical Care, Ambulatory Care, Maternal/Child and Emergency departments. A convenience sample of 45 registered nurses from nine subspecialty groups was selected for a focus group interview and five focus groups were selected for a study population. Findings of exit interviews (from 1 September 2001 to 28 February 2002) were also included in the data analysis. These exit interviews of RNs were conducted by Nurse Recruiter at the time of their resignations. The data analysis showed that the most dissatisfying factors at work and within the work setting were identified as: high workload, stress associated with high workload, biased Nursing Management, lack of appreciation and monetary incentives, finally a rigid attitude of Nursing Management. However, the most satisfying factors were: working with an internationally reputable organization, patients\u27 positive feedback and availability of required material or equipment. The study participants recommended that nursing retention could be improved at the Tertiary Care University Hospital by launching the following strategies by Nursing Management: reducing workload by adequate nurse-patient ratios according to international standards, promoting respect of nurses in front of patients and other staff, rewards and recognition of nurses, simplifying nursing documentation, increasing recreational activities for nurses and empowering nurses and Nursing Management group

Prevalence and correlates of stunting among children in rural Pakistan

Background: Protein-energy malnutrition remains an important underlying cause of death among preschool children in Pakistan. The present study aimed to estimate the prevalence of stunting and its correlates and to explore the role of sex bias in remote rural villages of south Pakistan.Methods: We selected 1878 children less than 3 years of age through stratified random sampling from 64 villages having the number of children enrolled proportionate to the size of each village, in rural Sindh, Pakistan. Trained investigators completed child physical measurements and a maternal interview. The Z-scores for the distribution of height-for-age (stunting) and weight-for-height (wasting) were estimated relative to those of the National Center for Health Statistics/Center for Disease Control (NCHS/CDC) reference population.Results: A total of 483 (26%) of the 1878 children were wasted, 977 (55%) were stunted and 259 (15%) were both wasted and stunted. Mothers who were illiterate were more likely to have children who were stunted (odds ratio (OR) = 1.27, 95% confidence interval (CI) 1.11-1.61). Fathers who earn less than Rs. 1000 (US $20) per month (OR = 1.35, 95% CI 1.12-1.66) were more likely to have children who were stunted. Children living in an overcrowded house were more likely to be stunted (OR = 1.44, 95% CI 1.18-1.75). Male children compared to females were equally likely to be stunted (57 vs 55%, OR 1.03, 95% CI 0.86-1.25).CONCLUSIONS: In this region of lower Sindh, stunting is more common than wasting. Female illiteracy, poor household income and overcrowding are important risk factors for stunting. The prevalent belief that in rural Pakistan, parents pay attention to feeding male children at the cost of female children is not proven by these data
