2024-05-07T14:54:52-03:00

Objective: To construct and validate educational pamphlets on oral antineoplastic therapy for patients with oncologic or hematologic diseases treated on an outpatient basis. Method: We carried out this research on two stages: a) Elaboration of educational pamphlets by the researchers, containing information regarding indication, administration mode, adverse effects, storage, and other precautions for the listed oral antineoplastics: Anagrelide, Cyclophosphamide, Chlorambucil, Melphalan, Lomustine, Mercaptopurine, Methotrexate, Mitotane, Pazopanib, Sorafenib, Temozolomide, Thioguanine, Ruxolitinib, and Tretinoin; b) Validation of the developed materials through a median grade among experts in the field (oncology and/or hematology pharmacists), using the Delphi Method, evaluating layout and content through a Likert scale. Data dispersion was assessed through the interquartile range (IQR), and adequate grade was defined as a median above 3. Results: The educational pamphlets were developed using national and international references, encompassing necessary information for the adequate and safe use of medications by patients. The initial validation involved 19 pharmacists specialized in oncology and/or hematology, spread across the national territory. In the first evaluation round, there was disagreement among experts on two issues, both related to the material’s content (highlighted sections and language used). After addressing points of disagreement, the pamphlets were validated by adequate grade among eight experts who remained in the study for the second round. Conclusion: It was possible to validate by experts the educational content of booklets containing written guidance on pharmacotherapy that will be delivered to the patient/caregiver, covering topics relevant to different medications, containing information with assertive scientific evidence, combining illustrations and language that is easy to understand by the population.

Microbiological characteristics and clinical profile of Stenotrophomonas maltophilia infections in a teaching hospital in northeastern Brazil

2024-06-14T12:06:40-03:00

Objective: This study aimed to elucidate the microbiological and clinical characteristics of patients affected by infection caused by S.maltophilia in a tertiary hospital in the north-east of Brazil. Methodology: The study consisted of a retrospective analysis of microbiological samples from January 2022 to September 2023 from the microbiology department of the Walter Cantídio University Hospital, Fortaleza, Ceará. The prevalence of these infections was determined, along with the epidemiology and antimicrobial sensitivity profile to sulphamethoxazole/trimethoprim (SMX-TMP) and levofloxacin. Clinical characteristics of the affected patients were identified, such as the use of mechanical ventilation (MV), hemodialysis (HD), previous use of antimicrobials and the outcome of these patients. Results: The prevalence of S.maltophilia infections was 1.79% in the period (35 positive samples and 26 affected patients). Of the positive clinical isolates, there was a predominance from the respiratory tract, with 23 samples (61.43%) from tracheal aspirates and 5 samples from bronchoalveolar lavage (14.57%). The highest number of positive samples was identified in the clinical ICU (23 isolates). About SMX-TMP, 65.71% of the strains were sensitive to increased exposure, 5.71% were fully sensitive and 28.57% were resistant. A profile of strains predominantly sensitive to levofloxacin was observed (91.49%), with 5.71% of the isolates proving sensitive by increasing exposure and 2.85% proving resistant. Women were more affected (57.69%). The average age was 54.33 years. Patients undergoing HD during the infection accounted for 53.84% of the profile obtained, while the use of MV occurred in around 69.23% of those infected. All patients had previously used antimicrobials. 19 patients (69.23%) died and only 7 were discharged from hospital (30.76%). Conclusion: With the findings, it was possible to determine a predominant profile of critically ill patients, with greater involvement of the respiratory tract. We also identified considerable rates of resistance to SMX-TMP, as well as an association between S. maltophilia infection and death.

Results: A total of 156 patients were included in the research and the analysis of their medical records and prescriptions revealed that the majority of these patients were male (n = 88, 56.4%), aged between 30 and 39 years ( n = 51, 32.7%), mixed ethnicity (n = 136, 87.2%), single marital status (n = 76, 48.7%), diagnosed with 1 mental disorder (n = 119, 76.3%), classified within the Spectrum of Schizophrenia and Other Psychotic Disorders (n = 80, 51.3%). The prescriptions contained a total of 5 or more medications (n = 105, 67.3%), with 2 or more antipsychotics (n = 116, 74.4%), hospital stay length of 6 to 16 days (n = 61, 39.1%). With regard to prescribed drugs, the main classes were antipsychotics, anxiolytics and antiepileptics. The most frequent drugs were haloperidol (n = 110, 70.5%), promethazine (n = 97, 62.2%), levomepromazine (n = 85, 54.5%), diazepam (n = 83, 53.2%), clonazepam (n = 79, 50.6%), biperiden (n = 52, 33.3%), midazolam (n = 41, 26.3%), risperidone (n = 39, 25.0%), and lithium carbonate (n = 37, 23.7%). Conclusion: The presence of polypharmacy, the high frequency of drugs with the potential to produce adverse effects, highlights the need for greater care with the pharmacotherapy of patients with mental disorders, whether in acute or thermal treatment, increasing patient adherence, improving their quality of life.

Simulation of the economic impact of introducing rivaroxaban in a high-complexity hospital for venous thromboembolism prophylaxis

2024-05-08T09:41:07-03:00

Objective: this work aims to simulate the economic impact of the introduction of rivaroxaban for venous thromboembolism (VTE) prophylaxis, when compared to the therapeutic options used in the institution (unfractionated heparin and enoxaparin), in the period from January to February 2022. Methods: In a retrospective study, we analyzed the possibility of replacing the prophylaxis used in the institution with prophylaxis with rivaroxaban based on the analysis of data from the electronic medical record system, taking into account the length of stay, the medications prescribed and compliance with the institutional protocol. Patients prescribed medication for VTE prophylaxis and indicated according to progress in the medical record were included, excluding those using non-pharmacological prophylaxis. Patients with contraindications to the use of rivaroxaban, such as pregnancy and liver impairment, were also excluded. Monte Carlo Simulation was used to calculate the cost of treatment with DOACs (Direct Oral Anticoagulants), using the medicines acquisition values during the study period, and a decision tree was constructed. Results: A total of 157 patients who were prescribed one of the heparins were evaluated. Of these patients, 98 (62.4%) could undergo prophylaxis with rivaroxaban as they had no contraindication to this treatment (price recorded in January/February 2022: R$ 0.23). This new prophylaxis would generate savings of up to 98.4% for enoxaparin 40 mg (price recorded in January/February: R$ 14.26), the item that had the highest consumption, corresponding to 71.4% of patients who could use it rivaroxaban. Conclusion: The implementation of rivaroxaban for venous thromboembolism prophylaxis replacing enoxaparin proved to be beneficial in terms of costs for the hospital, which suggests that more studies should be carried out in order to increase the robustness of results and support the incorporation of this technology in the institution.

Objective: To describe and analyze the pharmaceutical interventions performed by clinical intensivist pharmacists in the management of fluid therapy. Methods: This is an observational, retrospective, descriptive study conducted in a clinical ICU of a tertiary teaching hospital from January 2018 to December 2022. The study evaluated the classification according to the “four rights of fluid therapy” adapted from Hawkins14 (right drug, right dose, right route, and right patient); the acceptability of pharmaceutical interventions; the classification of interventions involving hidden fluids, and the medications involved in this classification. Results: The study included 415 patients, the majority of whom were male, 51% (213). The mean age was 57.4 ± 17.2 years. A total of 993 pharmaceutical interventions related to fluids were performed, comprising 12.2% of the interventions during the study period and corresponding to 2.4 per patient. The acceptability rate was 90% (894). Of the cited interventions, the majority (591) were related to the “right dose” (59.4%). The other interventions were: 167 (16.9%) related to the “right drug,” 163 (16.4%) to the “right route,” and 72 (7.2%) to the “right patient.” The management of hidden fluids was present in 722 (72.7%) interventions, with a focus on antimicrobials, totaling 256 (35.4%); followed by electrolytes and vitamins with 229 (31.7%), and antiulcer agents with 124 (17.2%). Conclusion: The pharmaceutical interventions analyzed were related to the “four rights of fluid therapy” and had high acceptability from the team. There was significant demand for pharmaceutical intervention in fluid management. The findings indicate the potential role of the clinical intensivist pharmacist as a key player in the fluid therapy management of critically ill patients.

Objective: Global healthcare costs continue to rise annually, and this is a major challenge given the scarce resources and growing prices of innovative drugs. An interesting alternative for reducing costs is the use of biosimilars. This study aimed to assess the financial impact of introducing biosimilars of the drugs adalimumab, rituximab and trastuzumab in a Cancer Institute of a Philanthropic Hospital in the South of the country. Method: This is a retrospective, descriptive study in which a budgetary impact analysis was used to assess the savings generated by the biosimilars standardized at the institution between January 2020 and December 2023. Information on the average cost and monthly consumption of the three biosimilars: adalimumab, rituximab and trastuzumab was used to assess the financial impact. The economic analysis was carried out using the difference between the cost of the biosimilar and the cost of the reference drug, multiplied by annual consumption. Results: It was evidenced during the study period the cost reduction after switching the reference biological with the corresponding biosimilar was R$ 1.540.701,18 (U$ 279.077,14) for adalimumab, R$ 129.824,93 (U$ 23.516,03) for rituximab and R$ 1.604.319,28 (U$ 290.600,70) for trastuzumab. The analysis identified that the standardization of biosimilars at the institution resulted in a global economy of R$ 3.274.845,39 (U$ 593.193,87). Conclusion: The use of biosimilars proved to be a more economical option when compared to the use of the reference biological. In conclusion, the use of biosimilars allows for a considerable reduction in overall treatment costs, especially in the case of innovative and expensive therapies. Therefore, the incorporation of biosimilars is considered an interesting option in the search for the sustainability of health systems.

2024-08-23T07:52:18-03:00

Objective: To characterize the medication use profile and evaluate the factors associated with serious and contraindicated potential drug-drug interactions (DDIs) in pharmacotherapy of people living with HIV (PLHIV). Method: This is a cross-sectional study, comprising two moments in the trajectory of PLHIV treatment - baseline and reevaluation. Sociodemographic, clinical and therapeutic variables were obtained from medical records and interviews. The medications used were classified using the Anatomical Therapeutic Chemical (ATC) system and potential DDIs were identified and classified according to the severity and quality of documentation using Micromedex®. Descriptive analyses were carried out to characterize the selected variables and the logistic regression method was used for univariate and multivariate analyses. Results: At baseline (n=247), the mean age was 36.8 years, with 60.3% being male. Potential DDIs were observed in 84.2% of participants. Upon the reevaluation (n=100), the mean age was 53.0 years, with a male majority (54.0%). Potential DDIs were observed in 63.8% of participants. There was a reduction in the proportion of anti-infectives and an increase in cardiovascular medications, when comparing the baseline and reevaluation. The number of medications (> 3) and the antiretroviral regimen remained associated with the occurrence of potential serious and contraindicated DDIs. Conclusion: The profile of medications used reflected the pattern of the most prevalent diseases in the periods evaluated. There was a reduction in the mean number of medications used and, consequently, a reduction in the number of DDIs at both moments, including those of greater severity.
