RESUMEN
Antibacterial drug resistance poses a significant challenge to modern healthcare systems, threatening our ability to effectively treat bacterial infections. This review aims to provide a comprehensive overview of the types and mechanisms of antibacterial drug resistance. To achieve this aim, a thorough literature search was conducted to identify key studies and reviews on antibacterial resistance mechanisms, strategies and next-generation antimicrobials to contain antimicrobial resistance. In this review, types of resistance and major mechanisms of antibacterial resistance with examples including target site modifications, decreased influx, increased efflux pumps, and enzymatic inactivation of antibacterials has been discussed. Moreover, biofilm formation, and horizontal gene transfer methods has also been included. Furthermore, measures (interventions) taken to control antimicrobial resistance and next-generation antimicrobials have been discussed in detail. Overall, this review provides valuable insights into the diverse mechanisms employed by bacteria to resist the effects of antibacterial drugs, with the aim of informing future research and guiding antimicrobial stewardship efforts.
RESUMEN
BACKGROUND: Although pharmaceutical care has tangible positive importance in ensuring patient pharmacotherapy safety, its provision encounters several barriers. Therefore, this study investigated the obstacles pharmacy professionals faced while providing pharmaceutical care in Motta town, Northwest Ethiopia. METHODS: A cross-sectional study was conducted from July 30, 2022, to August 30, 2022, at all community and hospital pharmacies in Motta town, Northwest Ethiopia. The data were collected via a self-administered questionnaire and analyzed via SPSS version 26.0. Descriptive statistics and statistical analysis tests, such as the independent t-test, variance, and multiple linear regressions, were employed to analyze the data. RESULTS: The study had a 97.7% response rate. Among the 130 participants, 71 (54.6%) were females. The mean (± SD) total score of pharmaceutical care provision barriers was 85.06 (± 20.2). The highest and lowest mean subscale scores of pharmaceutical care provision barriers were related to lack of resources and skill, respectively. Among resource-related barriers, lack of time and money, lack of trained staff, and lack of private space for consultation scored higher than other barriers. Concerning vision/attitudinal barriers, patients and other healthcare workers' inappropriate attitudes toward pharmaceutical care obtained the highest scores. The lack of clinical education in pharmaceutical care, lack of communication, and lack of documentation skills of pharmacists scored higher than other barriers in the educational and skill-related barriers subscales. For the regulatory/environmental subscale, a lack of clinical practice guidelines and legal barriers scored higher than the other subscales did. Pharmaceutical care provision barriers were significantly associated with age (B = 14.008), years of practice (B = 13.009), and graduating institution (B=-16.773). CONCLUSIONS: Resource and attitudinal/vision-related barriers were reported to be the most common barriers to pharmaceutical care implementation. Stakeholders should work together to develop strategic solutions to overcome these barriers and thus achieve optimal pharmaceutical care provision. These strategies should include optimizing the number of trained pharmacy staff, time and financial problems should be resolved, communication and documentation skills should be improved, pharmacy layouts should incorporate private counseling rooms, policies that support the pharmacist's role in patient care should be developed, and effective training and continuing professional education programs should be offered.
