RESUMO
PURPOSE: To test if two of the adverse event triggers proposed by the Institute of Healthcare Improvement can detect adverse drug events (ADEs) in a UK secondary care setting, using an electronic prescribing and health record system. METHODS: In order to identify triggers for over-anticoagulation and potential opioid overdose and we undertook a retrospective review of electronic medical and prescription records from 54,244 hospital admissions over a 1-year period, alongside a review of medical incident reports. Once prescription data were linked to triggers and duplicates were removed, case note review eliminated the false positive ADEs. Additionally, we tested the use of an electronic algorithm for the International Normalized Ratio (INR) ≥6 trigger. RESULTS: The INR ≥6 electronic trigger identified 46 potential ADEs and the naloxone electronic trigger identified 82 ADEs. Based on the available case note review, the INR ≥6 trigger had a positive predictive value (PPV) of 38 % (14/37) and the naloxone trigger had a PPV of 91 % (61/67). The electronic algorithm for the INR ≥6 trigger identified 12 ADEs, thus reducing the need of case note review. This was in comparison with one and two critical incidents reported in the trust medical incident reports system, which respectively related to over-coagulation with warfarin and over-sedation with opioid medication. CONCLUSIONS: We have integrated automated and manual methods of detecting ADEs using previously defined triggers. Incorporating electronic triggers in already established electronic health records with prescription and laboratory test data can improve the detection of ADEs, and potentially lead to methods to avert them.

BACKGROUND: The burden of healthcare-associated infection (HAI) is 2 to 18 times higher in developing countries. However, few data are available regarding infection prevention and control (IPC) process indicators in these countries. We evaluated hand hygiene (HH) facilities and compliance amongst healthcare workers (HCW) in a 600-bed healthcare facility in Northcentral Nigeria providing tertiary care service for a catchment population of about 20 million. METHODS: An in-house facility assessment tool and the World Health Organization (WHO) direct observation method were used to assess the HH facilities and compliance, respectively. Factors associated with good compliance were determined by multivariate analysis. RESULTS: The facility survey was carried out in all 46 clinical units of the hospital. 72% of the units had no poster or written policy on HH; 87% did not have alcohol-based hand rubs; 98% had at least one handwash sink; 28% had flowing tap water all day while 72% utilized cup and bucket; and 58% had no hand drying facilities. A total of 406 HH opportunities were observed among 175 HCWs. The overall compliance was 31%, ranging from 18% among ward attendants to 82% among medical students. Based on WHO "5 moments" for HH, average compliance was 21% before patient contact, 23% before aseptic procedure, 63% after body fluid exposure risk, 41% after patient contact and 40% after contact with patients' surrounding. Being a medical student was independently associated with high HH compliance, adjusted odds ratio: 13.87 (1.70-112.88). CONCLUSIONS: Availability of HH facilities and HCW compliance in a large tertiary hospital in Nigeria is poor. Our findings confirm that HCWs seem more sensitized to their risk of exposure to potential pathogens than to the prevention of HAI cross-transmission. Inadequate HH facilities probably contributed to the poor compliance. Specific measures such as improved facilities, training and monitoring are needed to improve HH compliance.

BACKGROUND: Medication errors are preventable causes of patient harm with significant contributions to adverse drug events but they remain understudied in Nigeria. OBJECTIVES: To estimate the prevalence of self-reported medication errors among health professionals and examine their knowledge of medication errors with the hope of identifying appropriate measures to promote medication safety. METHODS: A cross sectional survey among doctors, pharmacists and nurses in 10 tertiary hospitals. Information was obtained using a self-administered structured questionnaire. Correct responses evaluating the knowledge of prescription, dispensing and administration errors were scored one mark each and the composite scores computed. Appropriate statistics were applied to summarize and establish the relationship between variables at 5% level of significance using SPSS 17.0. RESULTS: A total of 2,386 professionals participated in the study (46.3% nurses, 44.9% doctors, 8.8% pharmacists).The prevalence of self-reported medication errors was 47%.The professional groups differ in their knowledge of all the aspects of medication errors with professional cadres influencing knowledge.Overwork was the most reason for being error prone (59.2%) and only 35.5% had ever reported medication error. 33.4% did not think reporting was necessary. CONCLUSIONS: The prevalence of medication errors is high among health care professionals in Nigeria. Knowledge gaps and practice deficiencies were identified requiring interventions.
