RESUMEN
Purpose: To evaluate the refractive and visual acuity outcomes when using trifocal toric intraocular lenses (IOLs), femtosecond laser assisted cataract surgery (FLACS), swept-source optical coherence tomography (SS-OCT) biometry, digital image tracking (DT) and intraoperative aberrometry (IA). Methods: This prospective, single-arm, observational study of refractive and visual outcomes included 40 eyes of 34 subjects. Preoperative biometry was performed with the Argos, FLACS and digital marking with LenSx, and IA and DT with ORA. Eyes were implanted with the Clareon PanOptix toric IOL. Study outcome measures included absolute prediction error, residual refractive astigmatism, and monocular uncorrected and distance corrected visual acuity at distance (UDVA, CDVA), intermediate (UIVA, DCIVA; 60cm), and near (UNVA, DCNVA; 40cm). Results: Mean absolute prediction error (spherical equivalent) was 0.43 ± 0.36 D, and the percentage of eyes with absolute prediction error ≤ 0.5 D was 72.5% (29/40 eyes). Mean residual astigmatism was 0.36 ± 0.65 D, and the percentage of eyes with residual astigmatism ≤ 0.5 D was 80% (32/40 eyes). Monocular UDVA, UIVA, and UNVA was 20/25 or better in 75%, 64%, and 87% of eyes respectively. Monocular CDVA, DCIVA, and DCNVA was 20/25 or better in 95%, 64%, and 87% of eyes respectively. Conclusion: The results of this study suggest that trifocal toric implantation with SS-OCT, FLACS, DT, and IA can provide excellent refractive and visual outcomes.
When the natural lens inside the eye becomes opaque (develops a cataract), it can be surgically replaced with a clear artificial intraocular lens (IOL). There are many different technologies available to the cataract surgeon in order to maximize postoperative visual outcomes with implanted IOLs. These include, modern biometers, femtosecond laser-assisted cataract surgery (FLACS), trifocal IOLs, toric IOLs, image-guided digital tracking (DT), and intraoperative aberrometry (IA). Individually, good refractive outcomes have been reported with these technologies. However, there is minimal data on outcomes using a combination of all of them. The purpose of this study was to determine the refractive and visual acuity outcomes when using modern biometers, toric IOLs, FLACS, DT, IA, and trifocal IOLs. The results of this study suggest that trifocal toric implantation with modern biometry, FLACS, DT, and IA can provide excellent refractive and visual outcomes.
RESUMEN
BACKGROUND: Medication errors significantly compromise patient safety in emergency departments. Although previous studies have investigated the prevalence of these errors in this setting, results have varied widely. AIM: The aim was to report pooled data on the prevalence and severity of medication errors in emergency departments, as well as the proportion of patients affected by these errors. METHOD: Systematic searches were conducted in Embase, PubMed, and the Cochrane Library from database inception until June 2023. Studies provided numerical data on medication errors within emergency departments were eligible for inclusion. Random-effects meta-analysis was employed to pool the prevalence of medication errors, the proportion of patients experiencing these errors, and the error severity levels. Heterogeneity among studies was assessed using the I2 statistic and Cochran's Q test. RESULTS: Twenty-four studies met the inclusion criteria. The meta-analysis gave a pooled prevalence of medication errors in emergency departments of 22.6% (95% Confidence Interval [CI] 19.2-25.9%, I2 = 99.9%, p < 0.001). The estimated proportion of patients experiencing medication errors was 36.3% (95% CI 28.3-44.3%, I2 = 99.8%, p < 0.001). Of these errors, 42.6% (95% CI 5.0-80.1%) were potentially harmful but not life-threatening, while no-harm errors accounted for 57.3% (95% CI 14.1-100.0%). CONCLUSION: The prevalence of medication errors, particularly those potentially harmful, underscores potential safety issues in emergency departments. It is imperative to develop and implement effective interventions aimed at reducing medication errors and enhancing patient safety in this setting.
RESUMEN
Introduction: In Vietnam, the prevalence of hypertension is increasing rapidly. Patients need to be conscious of the disease for timely prevention and treatment. The Hypertension Knowledge Level Scale (HK-LS) is commonly used to assess knowledge about hypertension. Methods: Data collection was took place in a hospital in Binh Thuan province, Vietnam in February 2020 with a total of 184 paticipants. Translation and adaptation of the HK-LS, validate the questionnaire through in-person interviews with outpatients diagnosed with hypertension. The translation process followed WHO guidelines. The appraisal process evaluates through reliability (Cronbach's alpha coefficient) and validity (meaningful relationship between the response results of the scale and the patient's characteristics). Results: The Vietnamese version of the HK-LS was translated and proven to be reliable (Cronbach's alpha=0.72) and valid (statistically significant difference between age groups (P=0.021) and educational background (P=0.007). Conclusion: The HK-LS was translated from English into Vietnamese; the questions are clear, intelligible, and suitable for surveying patients in Vietnam.
RESUMEN
OBJECTIVE: To evaluate a pharmacist-led intervention's effectiveness in reducing drug-related problems (DRPs ( related to prescriptions for pediatric outpatients. METHODS: We conducted a randomized controlled trial. We recruited and randomly assigned 31 physicians to control or intervention groups. We collected 775 prescriptions (375 from the control group and 400 from the intervention group) at the start. For 3 weeks, intervention physicians received additional information and meetings with pharmacists in addition to the usual practices of the hospital. We then collected prescriptions at the end of the study. We classified DRPs, based on reliable references (Supplemental Table S1) at baseline and endpoint (a week after the intervention). The primary outcome was the proportion of prescriptions with DRPs, and secondary outcomes were the proportions of prescriptions with specific DRP types. RESULTS: The influence of the intervention on general DRPs and specific DRPs was the study's main finding. The pharmacist-led intervention helped reduce the prescriptions with DRPs proportion in the intervention group to 41.0%, compared with 49.3% in the control group (p < 0.05). The DRPs proportion related to the timing of administration relative to meals, unlike the other DRP types, increased in the control group (from 31.7% to 34.9%) and decreased in the intervention group (from 31.3% to 25.3%), with a significant difference between the 2 groups at endpoint (p < 0.01). Patients aged >2 to ≤6 years (OR, 1.871; 95% CI, 1.340-2.613) and receiving ≥5 drugs (OR, 5.037; 95% CI, 2.472-10.261) were at greater risk of experiencing DRPs related to prescribing. CONCLUSIONS: A pharmacist-led intervention improved DRP occurrence related to physicians' prescribing. Pharmacists could be involved in in-depth research with physicians in the prescribing process to provide tailored interventions.
RESUMEN
Background: Children are at high risk of drug-related problems, increased risk of treatment failures, and high treatment costs. We aimed to evaluate the effect of pharmacist-led interventions on physicians' prescribing for pediatric outpatients. Methods: A prospective study with pre- and post-intervention measurement assessment was conducted to collect pediatric outpatients' prescriptions during the pre-intervention period (January 2020) and post-intervention (August 2020) at a children's hospital in Vietnam. Drug-related problems were identified and categorized according to Pharmaceutical Care Network Europe (PCNE), version 9.1. The intervention program was developed based on the results of pre-intervention observations. After the intervention, prescriptions were evaluated. Statistical tests were used to compare the proportions of drug-related problems before and after the intervention and to identify factors related to drug-related problems. Results: There were 2788 out of 4218 (66.1%) prescriptions with at least one drug-related problem before the intervention. Of these drug-related problems, the most common was inappropriate timing of administration and incorrect dosage (36.1% and 35.6%, respectively). After the intervention, the percentage of prescriptions with at least one drug-related problem was 45.5% (p < 0.001). Most of the drug-related problem types decreased significantly (p < 0.05). The binary logistic regression analysis results showed that in addition to pharmacists' intervention, patients' gender, primary disease, comorbidity status, and the total number of drugs prescribed were also factors related to drug-related problems. Conclusions: Drug-related problems in pediatric outpatients were quite common. Pharmacists' intervention helped to improve the prevalence and types of drug-related problems.
RESUMEN
BACKGROUND: We aimed to translate, cross-culturally adapt, and validate the General Medication Adherence Scale (GMAS) into Vietnamese. METHODS: We followed the guidelines of Beaton et al. during the translation and adaptation process. In Stage I, two translators translated the GMAS to Vietnamese. Stage II involved synthesizing the two translations. Stage III featured a back translation. Stage IV included an expert committee review and the creation of the pre-final version of the GMAS, and in stage V, pilot testing was conducted on 42 Vietnamese patients with type 2 diabetes. The psychometric validation process evaluated the reliability and validity of the questionnaire. The internal consistency and test-retest reliability were assessed by Cronbach's alpha and Spearman's correlation coefficients. The construct validity was determined by an association examination between the levels of adherence and patient characteristics. The content validity was based on the opinion and assessment score by the expert committee. The Vietnamese version of the GMAS was created, including 11 items divided into three domains. There was a good equivalence between the English and the Vietnamese versions of the GMAS in all four criteria. RESULTS: One hundred and seventy-seven patients were participating in the psychometric validation process. Cronbach's alpha was acceptable for all questionnaire items (0.817). Spearman's correlation coefficient of the test-retest reliability was acceptable for the GMAS (0.879). There are significant correlations between medication adherence levels and occupation, income, and the Beliefs about Medicines Questionnaire (BMQ) score regarding construct validity. CONCLUSIONS: The Vietnamese version of GMAS can be considered a reliable and valid tool for assessing medication adherence in Vietnamese patients.
RESUMEN
BACKGROUND: Chronic obstructive pulmonary disease (COPD) and asthma rank among the leading causes of respiratory morbidity, particularly in low- and middle-income countries. This qualitative study aimed to explore the healthcare pathways of patients with chronic respiratory disease, and factors influencing their ability to access healthcare in Vietnam, where COPD and asthma are prevalent. METHODS: We conducted 41 in-depth interviews among patients, including 31 people with COPD, eight with asthma and two with asthma-COPD overlap syndrome. Participants were recruited at provincial- or national-level health facilities in two urban and two rural provinces in Vietnam. The interviews were audio-recorded, transcribed, and analysed using thematic analysis. RESULTS: Patients' healthcare pathways were complex and involved visits to multiple health facilities before finally obtaining a definitive diagnosis at a provincial- or national-level hospital. Access to healthcare was affected considerably by participants' limited knowledge of their respiratory conditions, the availability of social support, especially from family members, the costs of healthcare as well as health system factors (including the coverage of public health insurance, the distance to health facilities, and attitude of healthcare providers). CONCLUSION: The study demonstrated the need for improved access to timely diagnosis and treatment of chronic lung disease within the lower level of the health system. This can be achieved by enhancing the communication skills and diagnostic capacity of local healthcare workers. Health education programmes for patients and caregivers will contribute to improved control of lung disease.

WHAT IS KNOWN AND OBJECTIVE: Coronary artery disease (CAD) is the leading cause of mortality worldwide. Patient education is an essential part of cardiac patients' care targeting self-management behaviour to reduce risk factors and subsequent events. There has been no Vietnamese questionnaire to assess patient's knowledge about CAD; therefore, the purpose of this study was to translate, cross-culturally adapt and validate the Coronary Artery Disease Education Questionnaire-Short Version (CADE-Q SV) for use in Vietnam. METHODS: Translation and cross-cultural adaption of the tool were carried out in five stages: (a) two independent translations from English into Vietnamese were produced; (b) these two translations were then synthesized; (c) two translators blinded to the outcome measurements independently created separate back translations into English; (d) nine experts reached consensus on all items of the Vietnamese version of the CADE-Q SV; and (e) a pilot study was conducted on 35 patients with acute coronary syndrome (ACS). The validity and reliability of the questionnaires were then evaluated in 117 Vietnamese patients with ACS. The internal consistency and test-retest reliability were assessed by Cronbach's alpha and Cohen's kappa coefficient, respectively. Construct validity was determined by examining the relationship between knowledge scores and patient characteristics. RESULTS: The Vietnamese version of CADE-Q SV was created, including 20 items divided into two domains: medical and psychological condition, and nutrition and exercise. There was good equivalence between the original and the Vietnamese versions in all four areas: semantic, idiomatic, experiential and conceptual equivalence. Cronbach's alpha coefficients were acceptable for the questionnaire as a whole (0.78) and for the two domains: medical and psychological condition (0.71) and nutrition and exercise (0.52). All Cohen's kappa coefficients confirmed test-retest reliability (Kappa > 0.600; P < .001). Construct validity was confirmed by a significant correlation of knowledge scores with education level (P = .004). WHAT IS NEW AND CONCLUSION: The Vietnamese version of CADE-Q SV can be considered a valid and reliable questionnaire to evaluate patient's knowledge of CAD. Further studies could investigate the influence of knowledge scores on adherence to medications and clinical outcomes of patients with CAD.

Health-related quality of life (HRQL) is a good indicator to monitor and evaluate healthcare services for adults with HIV/AIDS. This study described HRQL of adults with HIV and its determinants, and compared it with HRQL for the general population. A cross-sectional study with a national multistage sampling of households with and without HIV-positive people was conducted in 2008. Six provinces were purposively selected to represent areas of the country and progressions of HIV epidemics. Households were sampled with probability-proportional-to-size, following the selection of rural and urban districts. A total of 820 HIV-positive and HIV-negative adults (mean age: 32.5; 38.7% female) were interviewed. Among 400 HIV-positive people, 52.3% had a history of injecting drugs, and 56.3% were at AIDS stage and receiving antiretroviral treatment (ART). HRQL was measured using the EuroQOL five-dimension questionnaire (EQ-5D). Multiple regression models were purposefully constructed to examine the determinants of HRQL. The EQ-5D index and visual analog scale (VAS) score in less advanced HIV people (0.90, 69.3) and AIDS patients (0.88, 65.2) were significantly lower than those of the general population (0.96, 81.6) (p<0.001). The frequency of reported problems across EQ-5D dimensions in the HIV population (2.4-30.9%) was significantly higher than in the general population (0.7-12.1%). Compared to ART patients, those at earlier HIV stages reported having problems at similar proportions across four HRQL dimensions, except pain/discomfort, where ART patients had a significantly higher proportion. Injecting drug users taking ART perceived lower HRQL score than non-injecting drug users. Multiple regression determined that joblessness (p<0.01) and inaccessibility to health services (p<0.05) were associated with lower HRQL. In addition, involvements in self-help groups significantly improved HRQL among HIV-positive participants (p<0.05). The findings highlight the need to improve the health service referral system and enhance psychological and social supports for patients in early stages of HIV infection in Vietnam.
