Instruments to assess diabetes knowledge, skills and attitudes of people living with diabetes mellitus: A COSMIN-based systematic review

AIMS

Since knowledge, skills, and attitudes influence the adherence to self-care behaviours, the purpose of this review was to identify available instruments that measure diabetes knowledge, skills or attitudes of people living with this health condition and to evaluate their measurement properties.

METHODS

A systematic search was conducted in PubMed, EMBASE, SCOPUS, Web of Science and CINAHL databases. The methodological quality of the included studies was assessed by the Consensus-based Standards for the selection of health Measurement Instruments. Risk of Bias checklist. The results of each study were rated by the updated criteria for good measurement properties and the quality of evidence was graded using a modified Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

This review included 38 instruments that assess diabetes knowledge (n = 26) or skills (n = 6) or attitudes (n = 5) or both three constructs (n = 1). About 40% had satisfactory results for relevance, comprehensiveness, and comprehensibility, and about 30% had unsatisfactory results for comprehensiveness, but these results were supported by very low evidence. Most studies showed indeterminate results for structural validity (50%), internal consistency (98%) and reliability (84%). Instruments that had satisfactory results for construct validity and reliability were supported by low to very low evidence. One responsiveness study was identified, and the result was satisfactory, but supported by low evidence. The Diabetes Knowledge Questionnaire is the instrument with best evidence for use.

CONCLUSIONS

To plan more assertive interventions, researchers need to follow up guidelines to develop instruments with good quality of the measurement proprieties.

Validated medication deprescribing instruments for patients with palliative care needs palliative care: A systematic review

OBJECTIVES

Patients with life-limiting illnesses are prone to unnecessary polypharmacy. Deprescribing tools may contribute to minimizing negative outcomes. Thus, the aims of the study were to identify validated instruments for deprescribing inappropriate medications for patients with palliative care needs and to assess the impact on clinical, humanistic, and economic outcomes.

METHODS

A systematic review was conducted in LILACS, PUBMED, EMBASE, COCHRANE, and WEB OF SCIENCE databases (until May 2021). A manual search was performed in the references of enrolled articles. The screening, eligibility, extraction, and bias risk assessment were carried out by two independent researchers. Experimental and observational studies were eligible for inclusion.

RESULTS

Out of the 5,791 studies retrieved, after excluding duplicates (n = 1,050), conducting title/abstract screening (n = 4,741), and full reading (n = 41), only one study met the inclusion criteria. In this included study, a randomized controlled trial was conducted, which showed a high level of bias risk overall. Adults 75 years or older (n = 130) with limited life expectancy and polypharmacy were allocated to two groups [intervention arm (deprescribing); and control arm (usual care)]. Deprescribing was performed with the aid of the STOPPFrail tool. The mean number of inappropriate medications and monthly medication costs were significantly lower in the intervention arm. No statistically significant differences were found in terms of unscheduled hospital presentations, falls, fractures, mortality, and quality of life.

CONCLUSIONS

Despite the availability of several instruments to support deprescribing in patients with palliative care needs, only one of them has undergone validation and robust assessment for effectiveness in clinical practice. The STOPPFrail tool appears to reduce the number of inappropriate medications for older people with limited life expectancy (and probably palliative care needs) and decrease the monthly costs of pharmacotherapy. Nevertheless, the impact on patient safety and humanistic outcomes remain unclear.

Impact of the insertion of the clinical pharmacist in the Allogeneic Hematopoietic Stem Cells Transplantation team

INTRODUCTION

Allogeneic Hematopoietic Stem Cells Transplantation (allo-HSCT) is capable of curing patients with neoplastic or non-neoplastic hematologic disorders or of prolonging their survival. This study assessed if the insertion of the clinical pharmacist in the allo-HSCT team modified the outcomes: transplantation-related mortality, grafting failure, incidence of Graft versus Host Disease, hospitalization time, time for grafting, number of readmissions, number of drug-related problems (DRPs), adherence and knowledge about pharmacotherapy.

METHODS

Interventional study with historical control carried out in an allo-HSCT unit, in which the intervention group (IG) included 33 individuals who received pharmacotherapy follow-up. Control Group (CG) consisted of 28 individuals.

RESULTS

A total of 250 DRPs were identified, 59 team's doubts were clarified, and 309 interventions were conducted in the IG. The DRPs mainly arose from safety (51.60%) and effectiveness (38.40%) problems. A mean of 9.36 (SD = 6.97) interventions per patient was obtained, mainly including dose reductions (19.09%), adjustments in administration time (18.12%), educational activities (15.21%) and drug removal (10.68%). Clinical significance of the interventions was considered high (75.7% extremely significant, very significant or significant), as well as their acceptability (89.7% accepted). Each patient attended a mean of 4.68 pharmaceutical consultations (SD = 1.91) after hospital discharge, presenting increase in knowledge (p = 0.0001) and in adherence (p = 0.0115). There was no evidence of differences between the groups in the other outcomes analyzed.

CONCLUSIONS

The pharmacotherapy follow-up allowed detecting several DRPs and performing interventions of high clinical relevance and acceptability, in addition to improving adherence and individualizing the pharmacotherapy.

Can pharmacotherapeutic follow-up after allogeneic hematopoietic stem cell transplantation improve medication compliance?

BACKGROUND

Allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT) is currently one of the most effective therapies in onco-hematology. For the treatment of the disease and prevention of such complications, a complex pharmacotherapeutic regimen is employed. Non-compliance is prevalent among adolescents and young adults with chronic hematological diseases, being reported by up to 50% of the patients.

OBJECTIVE

To evaluate the results of pharmacotherapeutic follow-up on medication compliance and on the knowledge about pharmacotherapy of patients who underwent allo-HSCT.

METHODS

A single-arm, open-label and non-randomized intervention study developed in an allo-HSCT outpatient clinic. The participants attended pharmaceutical consultations and had their knowledge about pharmacotherapy and medication compliance measured by MedTake and Brief Medication Questionnaire (BMQ), respectively.

RESULTS

A total of 27 patients attended pharmaceutical consultations (4.81 consultations/patient; SD = 1.80). There was an improvement in medication compliance and in knowledge between the first and last consultations (p < 0.05). In the final consultation, 70.37% of the patients showed compliance, with a knowledge rate of 98.35% (SD = 3.63). Non-compliant individuals presented a greater tendency to hospital readmissions. There was no relationship between medication compliance and sociodemographic variables, graft-versus-host disease, and knowledge about pharmacotherapy.

CONCLUSIONS

Pharmacotherapeutic follow-up contributed to improving medication compliance. Knowledge about pharmacotherapy alone does not translate into behaviors, which corroborates the complexity of the biopsychosocial factors associated with medication compliance.

High-risk pregnancy: characterization of medication use profile and association with clinical and sociodemographic factors

Abstract Objectives: describe the profile of medication use and adherence, and the association with clinical and sociodemographic characteristics of high-risk pregnant women attended at a university hospital. Methods: cross-sectional study with data collected through a questionnaire applied on 386 pregnant women. Results: most participants were seen only by the gynecologist (75.1%), started prenatal in the first gestational trimester (86.8%), did not plan the pregnancy (61.9%), and performed an average of 8.2 (SD=4.4) prenatal consultations. The most frequent diagnoses were arterial hypertension (20.5%) and diabetes mellitus (19.7%). Prevalence of medication use was 99.7%, with an average of 5.1 (SD=2.1) medication per woman and 12.7% self-medication. Antianemics (88.9%) and analgesics (63.2%) were the most prevalent classes and 17.9% of the women reported the use of medication with significant gestational risk. Only 36.5% were considered adherent, 32.9% declared they were unaware of the indication of the medication in use and 42% did not receive guidance on the use of the medication during pregnancy. There is no evidence of association between the number of the medication used and clinical and sociodemographic aspects. Conclusions: there is a need to develop strategies to improve the care of this population, with emphasis on strengthening multi-professional care.

Antibiotic use in Brazilian hospitals in the 21st century: a systematic review

INTRODUCTION

This systematic review aimed to assess antibiotic use in Brazilian hospitals in the 21st century, as well as to understand the different drug utilization metrics adopted to assess the consumption of these drugs.

METHODS

We systematically reviewed five databases (MEDLINE [Medical Literature Analysis and Retrieval System Online], CENTRAL [The Cochrane Central Register of Controlled Trials], EMBASE® [Excerpta Medica Database], Scopus [Elsevier's abstract and citation database], and LILACS [Literatura Latino-Americana e do Caribe em Ciências da Saúde]) for observational or experimental studies that assessed antibiotic utilization in Brazilian hospitals. The main outcomes were the drug utilization metrics and the consumption of antibiotics.

RESULTS

We included 23 studies, of which 43.5% were carried out in adult and pediatric care units, 39.1% in adult units, and 17.4% in pediatric units. Regarding the complexity of healthcare, 26.1% of the studies were performed in intensive care units. Two drug utilization metrics were used in these studies: the defined daily dose (DDD) and the percentage of antibiotic prescriptions. The most commonly used antibiotic classes were third-generation cephalosporins, carbapenems, fluoroquinolones, and combinations of penicillins when the DDD was the adopted drug utilization metric.

CONCLUSIONS

Although few studies have been conducted, existing data indicate a high use of broad-spectrum antibiotics. We found that the lack of standardized antibiotic utilization metrics impaired the mapping of drug consumption at the national level.

Adequação da prescrição de medicamentos na Atenção Primária à Saúde de Ribeirão Preto-SP: estudo transversal

Objetivo: Este estudo transversal visa analisar comparativamente as prescrições de medicamentos provenientes da atenção básica tradicional (Unidades Básicas de Saúde - UBS) com as da Estratégia de Saúde da Família (ESF). Métodos: Foram incluídas 1053 prescrições, alocadas em dois grupos: 932 provenientes de UBS e 121 da ESF. Tais prescrições foram analisadas de acordo com a adequação aos itens legalmente exigidos e aos indicadores de qualidade (presença de antimicrobianos, presença de injetáveis, uso da denominação oficial, uso da relação de medicamentos essenciais, média de medicamentos prescritos). Resultados: As prescrições da ESF se mostraram estatisticamente mais completas quanto à presença do endereço do prescritor (82,6% UBS, 96,7% ESF), à ausência de rasuras (90,3% UBS, 96,7% ESF) e ao cumprimento dos aspectos legais exigidos referentes ao uso do medicamento, sendo eles: forma farmacêutica (70,7% UBS, 80,2% ESF), dose (70,9% UBS, 79,3% ESF), posologia (63,0% UBS, 75,2% ESF), via de administração (58,3% UBS, 83,5% ESF) e duração do tratamento (76,9% UBS, 92,6% ESF). Os resultados dos indicadores de qualidade da prescrição se aproximaram nos dois modelos de atenção básica e estão de acordo com os valores recomendados, com exceção da média de medicamentos prescritos, a qual evidenciou uma tendência à polifarmácia no município (3,9 medicamentos por prescrição na UBS e 3,5 na ESF). Conclusão: Apesar dos resultados revelarem práticas inapropriadas na prescrição de medicamentos na Atenção Primária como um todo, há evidências de que as prescrições da ESF estão mais próximas ao padrão ideal, o que pode favorecer o Uso Racional de Medicamentos.

Aquatic environments polluted with antibiotics and heavy metals: a human health hazard

Aquatic environments often receive wastewater containing pollutants such as antibiotics and heavy metals from hospital sewage, as well as contaminants from soil. The presence of these pollutants can increase the rate of exchange of resistant genes between environmental and pathogenic bacteria, which can make the treatment of various types of bacterial infections in humans and animals difficult, in addition to causing environmental problems such as ecological risk. In this study, two tetracycline-resistant Pseudomonas aeruginosa (EW32 and EW33), isolated from aquatic environments close to industries and a hospital in southeastern Brazil, were investigated regarding the possible association between tetracycline and heavy metal resistance. The isolate EW32 presented a conjugative plasmid with coresistance to tetracycline and copper, reinforcing the concern that antibiotic resistance by acquisition of plasmids can be induced by the selective pressure of heavy metals in the environment.
