Critical analysis of the regulations regarding the disposal of medication waste

Expired or unused medication at people's homes is normally disposed of in normal garbage, sewage system or, in certain cases, returned to the public health system. There is still no specific legislation regarding this leftover medication to regulate and orient the handling and correct disposal of medication waste. However, there is defined regulation regarding health services' solid waste. This article has the objective of discussing management models for the disposal of medication waste and the recommendations made by pertinent national and international legislation. By means of literature reviews, the management structure for medication waste of international legislation and the regulations regarding the environment, as well as the national legislation for the solid waste from health services was analyzed. Through the analysis it was possible to present better clarifications as to the possible impacts to the environment, to the public's health and alternatives in order to obtain the efficient disposal of medication, reducing and/or avoiding sanitary risk, guaranteeing the quality and safety of public health.

Medication adherence in frail elderly outpatients with dementia

Since drug therapy in the elderly is complex and longterm and aged people commonly present some level of impairment and disability, medication adherence tend to decrease with age. Cognitive function is a key factor associated with medication adherence and professional or caregiver assistance may be necessary to maintain correct drug use. This study aims to analyze frail elderly outpatients aged 80 years or over diagnosed with dementia. The study is cross-sectional and is being conducted at the Ambulatory of Frailty of the University Hospital of the University of São Paulo (AF-UH). It is being based on information collected through an interview conducted with the patient or its caregiver. Medication adherence is assessed by the proportion of the prescribed drugs used in concordance with the prescription. Here it is presented the results of a pilot study. Thirty patients were included in the pilot study of which 23 (76.7%) were female and 7 (23.3%) males. The mean(SD) age, number of dwelling relatives, living children and prescribed drugs was, respectively, 86(5) years, 3(2), 3(2) and 6(3). The AF-UH consultation is the only regular physician encounter for 60.7% of the patients. Out of 30 patients, 5 (16.7%) live alone. Medication is a caregiver responsibility in 22 (73.4%) patients; the others (26.6%) self-administer their medicines. 13 (43.3%) of patients regularly use at least one drug not prescribed. Dementia was present in 8 patients all of which have a caregiver responsible for the management and,or the administration of the medicines; on the other hand, only 4 of the 22 nondemented patients (18.2%) have assistance of a caregiver (p<.001). The mean(SD) number of prescribed drugs was higher in nondemented patients [6.5(2.4)] than in those with dementia[3.5(2.3)] (p=.004). Educational level was similar between caregivers and patients (p=.503) as well as between caregivers of demented and non demented patients (p=.582). Among patients without dementia, those with caregiver assistance pre-presented the same mean(SD) medication adherence [0.93(0.14)] than those without it [0.78(0.28)] (p=.305). When compared to nondemented patients without caregivers, demented patients showed higher medication adherence [1.00(0.00)] (p=.013) since all of them used their drugs as recommended. The lower number of prescribed drugs and caregiver assistance seem to play an important role in the adherence of pharmacotherapy of demented patients in the studied population.

Medication reconciliation and adherence: a call for clinical pharmacist

Introduction and Objectives: With the population ageing, there is a growing number of people who have several comorbidities and make use of a variety of drugs. These factors lead to a greater predisposition to adverse drug events, as well as to medication errors. The clinical pharmacist is the most indicated health professional to target these issues. The aims of this study were to analyze the profile of medication reconciliation and assess the role of the clinical pharmacist regarding medication adherence. Material and Methods: Prospective observational cohort study conducted from Jan-Mar 2013 at the Surgical Clinic of the University Hospital of the University of Sao Paulo. 117 admitted patients - over the age of 18 years, under continuous medication use and with length of hospitalization up to 120h - were included. Discrepancies were classified as intentional/unintentional and according to their risk to cause harm, and interventions were divided into accepted/not accepted. Medication adherence was measured by Morisky questionnaire. Results and Conclusions: Only 30% of hospital prescriptions showed no discrepancies between the medications that the patient was using at home and those which were being prescribed at the hospital and more than one third of those had the potential to cause moderate discomfort or clinical deterioration. One third of total discrepancies were classified as unintentional. About 90% of the interventions were accepted by the medical staff. In addition, about 63% of patients had poor adherence to drug therapy. The study revealed the importance of the medication reconciliation at patient admission, ensuring greater safety and therapeutic efficacy of the treatment during hospitalization, and orienting the patient at discharge, assuring the therapy safety.

Radiopaque stomach contents in postmortem CT in suicidal oral medication intoxication: report of three cases

In clinical medicine, plane radiography is used for detecting the remains of medications in the stomach in oral medication intoxication cases. Since postmortem computed tomography (CT), performed prior to autopsy, is currently intensively entering the forensic routine, the technique was applied to three fatal cases of oral medication intoxication. Here we report CT and autopsy findings for these cases. In all three cases, hyperdense areas within the stomach content were documented. The measurement of Hounsfield Units (HU) beyond 74HU showed mean values of 338, 88 and 98HU. Postmortem CT also showed brain edema and pulmonary aspiration in one case. At autopsy, tablet remains in the stomach were detected microscopically in all three cases. The ex vivo CT scans of the ingested medicaments showed similar HU values. Despite the fact that further case studies are necessary beyond this one, and in spite of its limitations, postmortem CT was found to be a useful screening and documentation method for stomach contents in oral medication intoxication.

Attention-deficit hyperactivity disorder (ADHD) and glial integrity: S100B, cytokines and kynurenine metabolism--effects of medication

Children with attention-deficit/hyperactivity disorder (ADHD) show a marked temporal variability in their display of symptoms and neuropsychological performance. This could be explained in terms of an impaired glial supply of energy to support neuronal activity.

Frequency of and predictors for patient-reported medical and medication errors in Switzerland

OBJECTIVES: To analyse the frequency of and identify risk factors for patient-reported medical errors in Switzerland. The joint effect of risk factors on error-reporting probability was modelled for hypothetical patients. METHODS: A representative population sample of Swiss citizens (n = 1306) was surveyed as part of the Commonwealth Fund’s 2010 lnternational Survey of the General Public’s Views of their Health Care System’s Performance in Eleven Countries. Data on personal background, utilisation of health care, coordination of care problems and reported errors were assessed. Logistic regression analysis was conducted to identify risk factors for patients’ reports of medical mistakes and medication errors. RESULTS: 11.4% of participants reported at least one error in their care in the previous two years (8% medical errors, 5.3% medication errors). Poor coordination of care experiences was frequent. 7.8% experienced that test results or medical records were not available, 17.2% received conflicting information from care providers and 11.5% reported that tests were ordered although they had been done before. Age (OR = 0.98, p = 0.014), poor health (OR = 2.95, p = 0.007), utilisation of emergency care (OR = 2.45, p = 0.003), inpatient-stay (OR = 2.31, p = 0.010) and poor care coordination (OR = 5.43, p <0.001) are important predictors for reporting error. For high utilisers of care that unify multiple risk factors the probability that errors are reported rises up to p = 0.8. CONCLUSIONS: Patient safety remains a major challenge for the Swiss health care system. Despite the health related and economic burden associated with it, the widespread experience of medical error in some subpopulations also has the potential to erode trust in the health care system as a whole.

Systematic review of medication safety assessment methods

Purpose The accuracy, efficiency, and efficacy of four commonly recommended medication safety assessment methodologies were systematically reviewed. Methods Medical literature databases were systematically searched for any comparative study conducted between January 2000 and October 2009 in which at least two of the four methodologies—incident report review, direct observation, chart review, and trigger tool—were compared with one another. Any study that compared two or more methodologies for quantitative accuracy (adequacy of the assessment of medication errors and adverse drug events) efficiency (effort and cost), and efficacy and that provided numerical data was included in the analysis. Results Twenty-eight studies were included in this review. Of these, 22 compared two of the methodologies, and 6 compared three methods. Direct observation identified the greatest number of reports of drug-related problems (DRPs), while incident report review identified the fewest. However, incident report review generally showed a higher specificity compared to the other methods and most effectively captured severe DRPs. In contrast, the sensitivity of incident report review was lower when compared with trigger tool. While trigger tool was the least labor-intensive of the four methodologies, incident report review appeared to be the least expensive, but only when linked with concomitant automated reporting systems and targeted follow-up. Conclusion All four medication safety assessment techniques—incident report review, chart review, direct observation, and trigger tool—have different strengths and weaknesses. Overlap between different methods in identifying DRPs is minimal. While trigger tool appeared to be the most effective and labor-efficient method, incident report review best identified high-severity DRPs.

Dual-energy CT-cholangiography in potential donors for living-related liver transplantation: Improved biliary visualization by intravenous morphine co-medication

PURPOSE: To prospectively evaluate whether intravenous morphine co-medication improves bile duct visualization of dual-energy CT-cholangiography. MATERIALS AND METHODS: Forty potential donors for living-related liver transplantation underwent CT-cholangiography with infusion of a hepatobiliary contrast agent over 40min. Twenty minutes after the beginning of the contrast agent infusion, either normal saline (n=20 patients; control group [CG]) or morphine sulfate (n=20 patients; morphine group [MG]) was injected. Forty-five minutes after initiation of the contrast agent, a dual-energy CT acquisition of the liver was performed. Applying dual-energy post-processing, pure iodine images were generated. Primary study goals were determination of bile duct diameters and visualization scores (on a scale of 0 to 3: 0-not visualized; 3-excellent visualization). RESULTS: Bile duct visualization scores for second-order and third-order branch ducts were significantly higher in the MG compared to the CG (2.9±0.1 versus 2.6±0.2 [P<0.001] and 2.7±0.3 versus 2.1±0.6 [P<0.01], respectively). Bile duct diameters for the common duct and main ducts were significantly higher in the MG compared to the CG (5.9±1.3mm versus 4.9±1.3mm [P<0.05] and 3.7±1.3mm versus 2.6±0.5mm [P<0.01], respectively). CONCLUSION: Intravenous morphine co-medication significantly improved biliary visualization on dual-energy CT-cholangiography in potential donors for living-related liver transplantation.

Psychotropic medication use in Swiss nursing homes

Psychotropic medication is commonly used in nursing homes, to treat behavioural and psychological symptoms of dementia (BPSD) for example. Treatment with antipsychotics may improve BPSD in some residents but can be associated with serious side effects, such as higher mortality, faster disease progression and cerebrovascular events. In the current study, psychotropic medication use was analysed in a representative sample of nursing home residents in the German-speaking part of Switzerland, at entry and during follow-up.

Ageing with HIV: medication use and risk for potential drug-drug interactions

Assessing Commonality and Differentiation for Packaging-Family Planning with Application to Medication Labels

This thesis presents a metric for assessing the commonality and differentiation of packaging-family planning with application to medical labels along with supporting background research and findings. Consumable products such as medications rely on the package or label to represent the contents. Package confusion has been widely recognized as a major problem for both over-the-counter and pharmacy-dispensed medications with potentially lethal consequences. It is critical to identify a medication as a member of a product family and differentiate its contributing elements based on visual features on the package or label to avoid consumer confusion and reduce dispensing errors. Indices that indicate degrees of commonality and differentiation of features in consumer products such as batteries, light bulbs, handles, etc for platforms have been shown to benefit development of engineered product families [6]. It is possible to take a similar approach for visual features in packaging such as typography, shape/form, imagery and color to benefit packaging-family development. This thesis establishes a commonality differentiation index for prominence of visual features on over-the-counter and pharmacy-dispensed medications based on occurrence, size, and location of features. It provides a quantitative measure to assist package designers in evaluating alternatives to satisfy strategic goals and improve safety. The index is demonstrated with several medications that have been identified by the Institute for Safe Medication Practice as commonly confused.

Medication errors in a swiss cardiovascular surgery department: a cross-sectional study based on a novel medication error report method

The purpose of this study was (1) to determine frequency and type of medication errors (MEs), (2) to assess the number of MEs prevented by registered nurses, (3) to assess the consequences of ME for patients, and (4) to compare the number of MEs reported by a newly developed medication error self-reporting tool to the number reported by the traditional incident reporting system. We conducted a cross-sectional study on ME in the Cardiovascular Surgery Department of Bern University Hospital in Switzerland. Eligible registered nurses (n = 119) involving in the medication process were included. Data on ME were collected using an investigator-developed medication error self reporting tool (MESRT) that asked about the occurrence and characteristics of ME. Registered nurses were instructed to complete a MESRT at the end of each shift even if there was no ME. All MESRTs were completed anonymously. During the one-month study period, a total of 987 MESRTs were returned. Of the 987 completed MESRTs, 288 (29%) indicated that there had been an ME. Registered nurses reported preventing 49 (5%) MEs. Overall, eight (2.8%) MEs had patient consequences. The high response rate suggests that this new method may be a very effective approach to detect, report, and describe ME in hospitals.

Gas embolism following intraosseous medication application proven by post-mortem multislice computed tomography and autopsy

The post-mortem use of modern imaging techniques such as multislice computed tomography (MSCT) is becoming increasingly important as an aid for conventional autopsy. This article presents a case of a 4-month-old boy who died from sudden infant death syndrome (SIDS) with intravascular gas after an intraosseus medication application documented by post-mortem MSCT. It is most likely that the gas entered the body during resuscitation. This case emphasises the advantage of post-mortem imaging as a complementary aid for the autopsy. We conclude that during emergency treatment, the medical staff should be aware of the possibility of causing a gas embolism following intraosseus medication. Resuscitation with an inserted, disconnected intraosseous needle should be avoided.

[Tooth extraction under medication with acetylsalicylic acid.]

PURPOSE: The purpose of this prospective study was to show and analyze the bleeding complications after teeth extraction under therapy with 100 mg acetylsalicylic acid (ASA) and to compare them to bleeding complications after teeth extraction in patients with a healthy blood profile.PATIENTS AND METHODS: In 65 patients under medication with 100 mg ASA and in 252 healthy patients, 151/ 543 teeth were extracted and the bleeding complications monitored.RESULTS: The postoperative bleeding frequency was 1.54% in the ASA 100 group and 1.59% in the healthy control group without any medication. No serious or uncontrollable postoperative bleedings arose in either group. All bleedings could be easily handled. No obvious difference concerning the bleeding frequency between the two groups was observed. The small number of bleeding events and the complexity of affecting parameters did not permit statistical tests.CONCLUSION: It is not necessary to interrupt the medication of 100 mg acetylsalicylic acid given to prevent thromboembolism before tooth extractions.
