Incidence of pressure injuries and risk factors in a paediatric surgical intensive care unit: a prospective cohort study.

OBJECTIVES: The aim of the study was to evaluate the incidence of, and risk factors for, the occurrence of pressure injuries (PIs) in a paediatric surgical intensive care unit (ICU). METHOD: This is a prospective cohort study of 153 children in the postoperative period. Patients were assessed daily by physical examination and data were collected. All independent variables were included in a logistic regression. RESULTS: The mean age of the cohort was 2 years, and the incidence of PI was 15.7%. According to the Braden Q Scale, 58.2% of patients were at high risk of developing PI; 79.3% of PIs were related to immobility and 69.0% were at stage 1. Risk factors were ICU length of stay and the number of medical devices used. CONCLUSION: The incidence of PI was high because patients were mostly at a considerable risk of developing a PI. PI was associated with several factors, especially length of ICU stay and number of devices, both of which are indirect indicators of the severity of patient condition and healthcare costs.

Haemodialysis, nutritional disorders and hypoglycaemia in critical care.

This study aimed to determine hypoglycemia incidence and associated factors in critically ill patients. It looked at a retrospective cohort with 106 critically ill adult patients with 48 hours of glycaemic control and 72 hours of follow up. The dependent variable, hypoglycaemia (≤70 mg/dl), was assessed with respect to independent variables: age, diet, insulin, catecholamines, haemodialysis, nursing workload and the Simplified Acute Physiology Score. Statistical analysis was performed using Student's t-test, Fisher's exact test and logistic regression at 5% significance level. Incidence of hypoglycaemia was 14.2%. Hypoglycaemia was higher in the group of patients on catecholamines (p=0.040), with higher glycaemic variability (p<0.001) and death in the intensive care unit (p=0.008). Risk factors were identified as absence of oral diet (OR 5.11; 95% CI 1.04-25.10) and haemodialysis (OR 4.28; 95% CI 1.16-15.76). Patients on haemodialysis and with no oral diet should have their glycaemic control intensified in order to prevent and/or manage hypoglycaemic episodes.

Self-medication among nursing students in the state of Amazonas - Brazil. / Automedicação em estudantes de enfermagem do Estado do Amazonas ­ Brasil.

OBJECTIVE: To determine the prevalence of self-medication and associated factors among nursing students. METHOD: This is a cross-sectional study with 116 nursing students from the public university in the state of Amazonas, Brazil, from March to April 2014. Data were collected using a questionnaire with socioeconomic and medicine use variables. The data were subjected to bivariate analysis and logistic regression at a significance level of 5%. RESULTS: The prevalence of self-medication was 76.0%, chiefly motivated by the belief that the health condition did not require a medical appointment (46.6%). Half of the students reported pain-related complaints. The most commonly used pharmacological groups were non-steroidal anti-inflammatory drugs (63.2%) and antibiotics (11.1%). Lack of awareness of the negative implications of self-medication was associated with self-medication (OR = 6.0). CONCLUSION: The high prevalence of self-medication that may lead to adverse reactions reveals the students' irrational use of medicines, especially considering the role of these future professionals in patient safety.

Patient safety in Intensive Care Units: development of a research project. / Segurança do paciente em Unidades de Terapia Intensiva: desenvolvimento de um projeto de pesquisa.

OBJECTIVE: To describe our experience in the many processes involved in the development of a Project on Research into Intensive Care Unit Patient Safety. METHOD: Mixed design study: historic cohort study of the collection of data on patients and on adverse events/incidents and transversal design on the collection of data on a nursing team. The data were collected over a period of 90 days in 2012 at the Instituto Central do Hospital das Clínicas da Faculdade de Medicina of the Universidade de São Paulo (ICHC-FMUSP)and the University Hospital of the Universidade de São Paulo HU-USP).Procedures carried out: This study involved a number of stages: application of the Nursing Activities Score (NAS) at the ICHC-FMUSP, creation of a database system, hospital record inputs, monitor training, patient data extraction and load, collection of data during duty shift changes, and records. Final considerations : Training, researcher commitment, and collaboration with IT (Information Technology) professionals were crucial to the quality of the results obtained and of scientific production achieved. We hope that our report will serve to guide and encourage researchers to carry out complex surveys contributing to improve nursing and health knowledge.

Nursing workload in hematopoietic stem cell transplantation: a cohort study. / Carga de trabalho de enfermagem em transplante de células-tronco hematopoiéticas: estudo de coorte.

Objective Measure nursing workload required by patients submitted to autologous and allogeneic hematopoietic stem cell transplantation (HSCT) and analyze the Nursing Activities Score (NAS) of the nursing team during the hospitalization period for HSCT. Method A prospective cohort study conducted from January 2013 to April 2014 with 62 patients hospitalized in the HSCT unit of a university hospital in Campinas, São Paulo, Brazil. The workload was measured through NAS and data analysis was through chi-square test or Fisher's exact test, Mann-Whitney test and Spearman's correlation coefficient; with 5% significance level. Results Mean nursing workload was 67.3% (SD of 8.2) in autologous HSCT patients and 72.4% (SD of 13.0) in allogeneic HSCT patients (p=0.1380).Monitoring and titration showed, in more than 50% of the time, patients demanded intensified care, requiring two hours or more in a nursing shift for reasons of safety, severity or therapy. Conclusion The nursing workload and the NAS items with the highest scores reflect the magnitude, complexity and specificity of care required by patients submitted to HSCT.

Assessment of workload in the postoperative period of cardiac surgery according to the Nursing Activities Score. / Avaliação da carga de trabalho no pós-operatório de cirurgia cardíaca segundo o Nursing Activities Score.

Objective Identify factors associated with the workload of nursing care for patients in the postoperative period of cardiac surgery. Method Prospective cohort study conducted with 187 patients in the surgical intensive care unit (ICU) of the Instituto do Coração(Heart Institute) in São Paulo-Brazil. Data were collected at 24 and 72 hours of the patients' admittance in the ICU. The dependent variable was workload as calculated by the Nursing Activities Score (NAS). The independent variables were demographic and clinical, as well as mortality scores. For data analysis, the Wilcoxon-Mann-Whitney test and Spearman correlation were used, and linear regression with mixed effects model. Results The majority of patients were male (59.4%), with a mean age of 61 years (±12.7), and 43.9% developed some kind of complication in the postoperative period. In the first 24 hours, the workload was 82.4% (±3.4), and 58.1% (±3.4) in 72 hours. Factors associated with increased NAS were: patient's length of stay in the ICU (p=0.036) and the presence of complications (p<0.001). Conclusion In contrast to numerous other studies, the severity of the patient's condition in the first 24 hours of the postoperative period did not increase workload, the increase was associated with length of stay in the ICU and complications.

[Insulin infusion in intensive care: randomized controlled trial]. / Infusão de insulina em terapia intensiva: ensaio controlado randomizado.

This randomized controlled trial compared the use of an intensive and conventional insulin protocol on clinical outcomes in patients with severe sepsis and septic shock, in the first 72 hours. It was conducted at a university hospital in the city of São Paulo. Patients (n=46) were allocated into two groups: intensive glycemic (blood glucose between 80-110mg/dl) and conventional (180-220mg/dl). The Student's t-test and chi-square test were used for data analysis. A statistically significant (p<0.001) difference was observed in mean glycemia, but there was no difference in the variables of mean minimum arterial pressure (p=0.06) or maximum (p=0.11), serum creatinine (p=0,33) or in mortality (p=0.11). Although there was no difference between the groups regarding mortality, hemodynamic instability in the conventional group was longer and the only deaths occurred in it.

Potentially inappropriate medications with older people in intensive care and associated factors: a historic cohort study.

BACKGROUND: The epidemiology of potentially inappropriate medications (PIMs) in critical care units remains limited, especially in terms of the factors associated with their use. OBJECTIVE: To estimate the incidence and factors associated with PIMs use in intensive care units. DESIGN AND SETTING: Historical cohort study was conducted in a high-complexity hospital in Brazil. METHODS: A retrospective chart review was conducted on 314 patients aged ≥ 60 years who were admitted to intensive care units (ICUs) at a high-complexity hospital in Brazil. The dates were extracted from a "Patient Safety Project" database. A Chi-square test, Student's t-test, and multivariable logistic regression analyses were performed to assess which factors were associated with PIMs. The statistical significance was set at 5%. RESULTS: According to Beers' criteria, 12.8% of the identified drugs were considered inappropriate for the elderly population. The incidence rate of PIMs use was 45.8%. The most frequently used PIMs were metoclopramide, insulin, antipsychotics, non-steroidal anti-inflammatory drugs, and benzodiazepines. Factors associated with PIMs use were the number of medications (odds ratio [OR] = 1.17), length of hospital stay (OR = 1.07), and excessive potential drug interactions (OR = 2.43). CONCLUSIONS: Approximately half of the older adults in ICUs received PIM. Patients taking PIMs had a longer length of stay in the ICU, higher numbers of medications, and higher numbers of potential drug interactions. In ICUs, the use of explicit methods combined with clinical judgment can contribute to the safety and quality of medication prescriptions.

[Factors associated to the use of psychotropic drugs by community-dwelling elderly in São Paulo city]. / Fatores associados ao uso de psicotrópicos por idosos residentes no Município de São Paulo.

The objectives of study were to identify the prevalence and factors associated to the use of psychotropic drugs among elderly people in São Paulo city. It is a cross-sectional study. Data were used from the SABE survey (for Health, Well-being and Ageing). The sample was constituted of 1.115 elderly people, aging 65 and over, which were interviewed by standard method. In the data analysis, it was used univariate and multiple logistic regression, stepwise forward and level of significance of 5%. The prevalence of the use of psychotropic drugs of 12,2% and the factors associated were female gender (OR=3,04 IC95%= 1,76-5,23) and polypharmacy (OR=4,91 IC95%=2,74-8,79). The use of psychotropics drugs by the elderly must have their benefits and risks very well established. Elder women, especially those who were submitted to a polipharmacy, deserve special attention to adjust dosage and duration of the treatment, with the purpose of minimizing the adverse outcomes.

[Cross-cultural adaptation of the Vulnerable Elders Survey-13 (VES-13): helping in the identification of vulnerable older people]. / Adaptação transcultural do Vulnerable Elders Survey-13 (VES-13): contribuindo para a identificação de idosos vulneráveis.

To use the VES-13 a tool for identifying vulnerable older people cultural adaptation was performed, a process that seeks the equivalence between the original instrument and its version in another culture. The evaluation of semantic, idiomatic, cultural and conceptual equivalence obtained a general average agreement of 78%, 78%, 97.0% and 94.0% respectively. Kappa coefficient was used to verify the agreement in test-retest reliability, where variables were significant. The analysis of internal consistency was measured by using Cronbach's alpha coefficient, where 70% of the phenomenon under study are represented in the VES-13. The VES-13, translated and adapted, is a reliable instrument with respect to stability and internal consistency of their measurements. Its simple structure and easy to use may therefore contribute to the identification of vulnerable older people, thus contributing to the prioritization of monitoring health services.

[Patterns of food consumption in riverine communities in the mid-Solimões river region - Amazonas - Brazil]. / Padrões de consumo alimentar nas comunidades ribeirinhas da região do médio rio Solimões - Amazonas - Brasil.

This is a cross-sectional study conducted with 492 riverine residents in the rural area of Coari (AM) to identify food patterns in the mid-Solimões river region and associated factors. Food intake was evaluated using a brief Food Frequency Questionnaire (FFQ), and principal component analysis was used to identify dietary patterns. The association with socioeconomic variables was evaluated using generalized linear models. Four dietary patterns were identified: "vegetables" (vegetables, tubers, fruit); "Brazilian" (chicken, eggs, rice, beans); "traditional riverine" (fish, flour, milk); "meat and candies" (game and pork, candies). The "vegetable" pattern was associated with education (p = 0.001), number of rooms in the house (p = 0.005) and greater proximity to urban areas (p = 0.004). The "Brazilian" pattern was associated with the female sex (0.013), higher income (p < 0.001) and greater proximity to urban areas (p = 0.001). The "traditional riverine" pattern was associated with distance from the urban area (p < 0.001), and the "meat and candies" pattern was associated with age (p = 0.029), education (p < 0.001) and proximity to urban areas (p = 0.003). The extractive nature of riverine food intake is still present in more isolated communities, and consumption of other food items was associated with better social conditions.

Estudo transversal conduzido na zona rural de Coari (AM) com o objetivo de identificar padrões alimentares de 492 ribeirinhos da região do médio rio Solimões e fatores associados. Utilizou-se um questionário de frequência alimentar breve na avaliação do consumo alimentar. Padrões alimentares foram identificados a partir da análise de componentes principais, analisaram-se associações entre cada padrão e variáveis sociodemográficas utilizando-se modelos lineares generalizados. Identificaram-se quatro padrões alimentares: "vegetais" (vegetais, tubérculos, frutas); "brasileiro" (frango, ovos, arroz, feijão); "ribeirinho tradicional" (peixe, farinha, leite); "carnes e doces" (carnes de caça e de porco, doces). O padrão "vegetais" associou-se a escolaridade (p = 0,001), número de cômodos da residência (p = 0,005) e menor distância da área urbana (p = 0,004). O "brasileiro" associou-se a sexo feminino (p = 0,013), maior renda (p < 0,001) e menor distância da área urbana (p = 0,001). O padrão "ribeirinho tradicional" associou-se à distância da área urbana (p < 0,001), e o padrão "carnes e doces" a idade (p = 0,029), escolaridade (p < 0,001) e distância da área urbana (p = 0,003). O caráter extrativista da alimentação ribeirinha está presente nas comunidades mais isoladas, e o consumo de outros alimentos foi associado a melhores condições sociais.

In(compatibility) of intravenous drugs in critical units: adult cohort.

OBJECTIVES: To analyze potential (in)compatibilities of intravenous drugs based on the scheduling prepared by the nursing team. METHODS: historic cohort (retrospective) with 110 adults in critical units. Intravenous medications were identified concomitantly, whose pairs were analyzed for (in) compatibility using the screening system Trissel's™ 2 Compatibility IV-Micromedex 2.0. Parametric and non-parametric statistic were used according to the nature of the variable. RESULTS: 565 pairs of drugs were identified. Of these, 44.9% were compatible; and 8.8%, potentially incompatible. Most potentially incompatible pairs involved substances with alkaline pH such as phenytoin (32%) and sodium bicarbonate (8%) and weak acids such as midazolam (12%) and dobutamine (6%), which could result in precipitate formation. CONCLUSIONS: almost half of the mixtures simultaneously administrated was compatible, which indirectly reflects in the organized work between the nursing team and the clinical pharmaceutic in the discussions and decisions related to time scheduling.

[Polypharmacy: interaction and adverse reactions in the use of drugs by elderly people]. / Polifarmácia: interações e reações adversas no uso de medicamentos por idosos.

The article has for objective to reflect on the polypharmacy of the aged with emphasis in the adverse drug reactions and the drug-drug interactions. The vulnerability of the elderly to the problems related from the use as of drugs is pretty upswing, the one to in case that must the complexity of the problems clinical, at the must as of need pharmacotherapeutic interventions, and to the update pharmacokinetic and pharmacodynamic changes inherent to the aging. In this way, to rationalize the drugs utilization and to avoid the injury related to the polypharmacy will be, doubtless, one of the biggest challenges for public health in this century.

Self-medication practices in riverside communities in the Brazilian Amazon Rainforest.

OBJECTIVES: to analyze the practice of self-medication and the associated factors in the riverside population of the Middle Solimões river region - Amazon rainforest. METHODS: a cross-sectional population-based study conducted between April and July 2015, through interviews at home. RESULTS: the prevalence of self-medication among the riverside population was 76.3%. Analgesics and antibacterials were the main therapeutic classes used in self-medication. Self-medication proved to be associated with the male gender, young people, not having sought the health service in the last month, longer commuting from the community to the urban area and the habit of consuming allopathic medicines on their own. CONCLUSIONS: self-medication among the riverside population of Coari - Amazon may reflect the need to seek self-care by people, with the use of allopathic medicines without prescription, mainly due to the restricted access to health services.

[A comparison between two catheters for clean intermittent catheterization in continent children with a urostomy]. / Estudo comparativo sobre dois tipos de cateteres para cateterismo intermitente limpo em crianças estomizadas.

The objective of this crossover study was to compare the use of two catheters for clean intermittent catheterization in continent children with a urostomy, in terms of their handling, complications and direct costs. This study complied with all ethical requirements and was developed at a Children's Hospital in the city of São Paulo. The children who, together with their guardians, agreed to participate in the study were submitted to the consecutive use of both the traditional and the pre-lubricated catheter, for one month each. During that period, the children completed the data collection instruments and were followed by the researchers once a week through home visits and hospital consultations, including quantitative and qualitative urine cultures that were performed every other week. Data analysis was performed using Wilcoxon and Kaplan-Meier tests. Eleven children completed the study. Statistical significant differences were found only for costs (p = 0.003), which were higher for pre-lubricated catheters.

[Medication: ethical and legal aspects for nursing]. / Medicação: aspectos ético-legais no âmbito da enfermagem.

This article treats of the duties and responsibilities of nursing staff concerning medication process. From a survey about the valid legislation, the authors made considerations about the legal implications to the nursing staff, especially related to the assistance quality detours involving the medication process, as well as the contradictions in law that restrict the information access about medication to these professionals.

Economic burden of inpatients infected with Klebsiella pneumoniae carbapenemase.

OBJECTIVE: To estimate the direct medical costs of drug therapy of Klebsiella pneumoniae carbapenemase (KPC) infection patients in hospital-based context. METHODS: A cost-of-illness study conducted with a prospective cohort design with hospitalized adults infected by KPC. Data collection was performed using an instrument composed of sociodemographic data, clinical and prescription medication. Estimates of the direct costs associated to each treatment were derived from the payer's perspective, in the case of federal public hospitals from Brazil, and included only drug costs. These costs were based on the average price available at the Brazilian Price Database Health. No discount rate was used for the cost of drugs. The costs are calculate in American Dollar (US$). RESULTS: A total of 120 inpatients participated of this study. The total drug cost of these inpatients was US$ 367,680.85. The systemic antimicrobial group was responsible for 59.5% of total costs. The direct drug cost per patients infected by KPC was conservatively estimated at nearly US$ 4,100.00, and about of 60% of costs occurred during the period of infection. CONCLUSION: The findings of our study indicate a thoughtful economic hazard posed by KPC that all healthcare sectors have to face. The increasing worldwide incidence of these bacteria represents a growing burden that most health systems are unable to deal with. There is an imperative need to develop protocols and new antimicrobials to treatment of KPC, aiming to rearrange resources to increase the effectiveness of healthcare services.

Cost-effectiveness of antimicrobial treatment for inpatients with carbapenem-resistant Klebsiella pneumoniae infection: a systematic review of economic evidence.

OBJECTIVES: The objective of this review was to evaluate the cost-effectiveness of antimicrobial therapy for patients with carbapenem-resistant Klebsiella pneumoniae infection. INTRODUCTION: Among the main multi-resistant microorganisms, carbapenem-resistant K. pneumoniae is responsible for the mortality of 40% of patients following 30 days of infection. Treatment for carbapenem-resistant K. pneumoniae infection entails the use of high-cost antimicrobials. Inappropriate use of antimicrobials can increase the cost of treatment fourfold. This review aimed to evaluate the cost-effectiveness of antimicrobial therapy treatment for patients with carbapenem-resistant K. pneumoniae infection to better inform decision making in hospital services. INCLUSION CRITERIA: The review included studies on participants 18 years or over with carbapenem-resistant K. pneumoniae infection who had undergone antimicrobial therapy in hospital and acute care services. Studies that compared the cost-effectiveness of different antimicrobial therapy for carbapenem-resistant K. pneumoniae infection were included. Outcome measures were cost per unit of effect expressed in clinical outcome units; this included cost per avoided death, cost per prevention of sepsis and cost per duration of stay. Economic studies with a cost-effectiveness design were considered, as well as modeling studies. METHODS: A three-step search strategy was utilized to locate studies published in English, Spanish or Portuguese, with no date restrictions. Two independent reviewers screened titles and abstracts and the full texts of potentially relevant studies for eligibility. Methodological quality was assessed by two independent reviewers using the JBI critical appraisal checklist for economic evaluations. Data were extracted from included studies using the standardized JBI data extraction tool. Data were synthesized using narrative, tables and the JBI Dominance Ranking Matrix. RESULTS: This review identified eight studies that evaluated the cost-effectiveness of different treatments for carbapenem-resistant K. pneumoniae infection. The results of this study demonstrated that there was no gold standard treatment for carbapenem-resistant K. pneumoniae infection, hence treatment was generally directed by colonization pressure and resistance profiles. Furthermore, due to the moderate quality and limited number of studies, there was high uncertainty of the values of the cost-effectiveness ratio. CONCLUSIONS: Ofloxacin appears to be the most cost-effective treatment; however, conclusions are limited due to the small number and low quality of studies.

Survival of the elderly and exposition to polypharmacy in the city of São Paulo, Brazil: SABE Study. / Sobrevida de idosos e exposição à polifarmácia no município de São Paulo: Estudo SABE.

INTRODUCTION: The use of polypharmacy may be due to the concomitant presence of chronic conditions, medical care by several doctors simultaneously and self-medication. Combined with the vulnerability of the elderly to the effects of drugs due to pharmacokinetic and pharmacodynamic changes, polypharmacy makes this population more susceptible to adverse outcomes. In Brazil, studies show that polypharmacy is a common problem among elderly people. However, few information is available on the association between polypharmacy and mortality. OBJECTIVE: It was assessed the survival of the elderly from São Paulo city exposed to the use of polypharmacy (five or more medications). METHODS: That was a population-based cohort, the Health, Well-Being and Aging Study (SABE Study), conducted from 2006 to 2010. The sample was composed of 1,258 individuals aged 60 years or more. The Kaplan-Meier method and Cox proportional risks model were used to examine the association between polypharmacy and mortality. RESULTS: The probability of survival after five years of the users of polypharmacy at baseline was 77.2%, while among the non-users was 85.5%. Polypharmacy remained as a risk factor for death even after adjustment in other conditions associated with mortality, such as age, gender, income, chronic diseases and hospitalization. CONCLUSION: The results point polypharmacy as an indicator of mortality in elderly people. The use of multiple medications by the elderly should be carefully assessed to avoid or minimize the damage to this population.

INTRODUÇÃO: O uso de polifarmácia pode ser resultante da presença concomitante de condições crônicas, atendimento por diversos médicos e automedicação. Combinada com a vulnerabilidade de idosos aos efeitos dos medicamentos devido a alterações farmacocinéticas e farmacodinâmicas, a polifarmácia torna essa população mais suscetível a desfechos adversos. No Brasil, estudos mostram que a polifarmácia é um problema frequente entre idosos, mas faltam informações sobre sua associação com mortalidade. OBJETIVO: Avaliar a sobrevida de idosos do município de São Paulo expostos ao uso de polifarmácia (cinco ou mais medicamentos). MÉTODOS: Trata-se de uma coorte de base populacional, o Estudo Saúde, Bem-Estar e Envelhecimento (Sabe), da qual se pesquisou o seguimento de 2006 a 2010. A amostra foi composta por 1.258 indivíduos com 60 anos ou mais. O método de Kaplan-Meier e o modelo de riscos proporcionais de Cox foram usados para examinar a associação entre mortalidade e polifarmácia. RESULTADOS: A probabilidade de sobrevida após cinco anos dos indivíduos usuários de polifarmácia na linha de base foi de 77,2%, enquanto nos não usuários foi de 85,5%. Apolifarmácia permaneceu como fator de risco para óbito mesmo após ajuste de demais condições associadas à mortalidade, como idade, sexo, renda, doenças crônicas e internação hospitalar. CONCLUSÃO: Os resultados apontam para a polifarmácia como um preditor de mortalidade para pessoas idosas. O uso de múltiplos medicamentos por idosos deve ser cuidadosamente avaliado para evitar ou minimizar danos a essa população.

Potentially inappropriate medications with older people in intensive care and associated factors: a historic cohort study

ABSTRACT BACKGROUND: The epidemiology of potentially inappropriate medications (PIMs) in critical care units remains limited, especially in terms of the factors associated with their use. OBJECTIVE: To estimate the incidence and factors associated with PIMs use in intensive care units. DESIGN AND SETTING: Historical cohort study was conducted in a high-complexity hospital in Brazil. METHODS: A retrospective chart review was conducted on 314 patients aged ≥ 60 years who were admitted to intensive care units (ICUs) at a high-complexity hospital in Brazil. The dates were extracted from a "Patient Safety Project" database. A Chi-square test, Student's t-test, and multivariable logistic regression analyses were performed to assess which factors were associated with PIMs. The statistical significance was set at 5%. RESULTS: According to Beers' criteria, 12.8% of the identified drugs were considered inappropriate for the elderly population. The incidence rate of PIMs use was 45.8%. The most frequently used PIMs were metoclopramide, insulin, antipsychotics, non-steroidal anti-inflammatory drugs, and benzodiazepines. Factors associated with PIMs use were the number of medications (odds ratio [OR] = 1.17), length of hospital stay (OR = 1.07), and excessive potential drug interactions (OR = 2.43). CONCLUSIONS: Approximately half of the older adults in ICUs received PIM. Patients taking PIMs had a longer length of stay in the ICU, higher numbers of medications, and higher numbers of potential drug interactions. In ICUs, the use of explicit methods combined with clinical judgment can contribute to the safety and quality of medication prescriptions.
