Clinical versus fixed warfarin dosing and the impact on quality of anticoagulation (The ClinFix trial).

Different dosing strategies exist to initiate warfarin, most commonly fixed warfarin dosing (FWD), clinical warfarin dosing (CWD), and genetic-guided warfarin dosing (GWD). Landmark trials have shown GWD to be superior when compared to FWD in the EU-PACT trial or CWD in the GIFT trial. COAG trial did not show differences between GWD and CWD. We aim to compare the anticoagulation quality outcomes of CWD and FWD. This is a prospective cohort study with a retrospective comparator. Recruited subjects in the CWD (prospective) arm were initiated on warfarin according to the clinical dosing component of the algorithm published in www.warfarindosing.org. The primary efficacy outcome was the percentage time in the therapeutic range (PTTR) from day 3 to 6 till day 28 to 35. The study enrolled 122 and 123 patients in the CWD and FWD, respectively. The PTTR did not differ statistically between CWD and FWD (62.2 ± 26.2% vs. 58 ± 25.4%, p = 0.2). There was also no difference between both arms in the percentage of visits with extreme subtherapeutic international normalized ratio (INR) (<1.5; 15 ± 18.3% vs. 16.8 ± 19.1%, p = 0.44) or extreme supratherapeutic INR (>4; 7.7 ± 14.7% vs. 7.5 ± 12.4%, p = 0.92). We conclude that CWD did not improve the anticoagulation quality parameters compared to the FWD method.

Impact of pharmacist-supported transition of care services in the Middle East and North Africa: a systematic review and meta-analysis.

Background: Transition of care (TOC) is associated with an increased risk of medication-related problems. Despite recent advancements in pharmacy practice and research in the Middle East and North Africa (MENA), the characteristics and impact of regional pharmacy-supported TOC interventions remain unclear.This systematic review and meta-analysis aimed to describe pharmacist-supported TOC interventions in the MENA region and evaluate their effectiveness. Methods: PubMed, CINAHL, EMBASE, Web of Science, World Health Organization's International Clinical Trials Registry Platform (ICTRP) were searched from their inception to March 9, 2023, for experimental studies published in English, comparing pharmacist-supported TOC interventions with usual care for adults (age ≥18 years) discharged from the hospital. The risk of bias was evaluated using Cochrane's risk-of-bias tool for randomised trials (ROB2) and the risk of bias in non-randomised studies of interventions (ROBINS-I) tool for randomised and non-randomised studies respectively. Narrative syntheses and meta-analysis methods were employed depending on the outcomes evaluated. Results: Twelve studies (n = 2377 subjects), 10 randomised controlled trials and 2 quasi-experimental studies, were included. Most studies had high or serious risk of bias. The included studies were quite heterogeneous in terms of nature and the delivery of intervention, and assessment of outcome measures. Compared to the usual care group, pharmacist-led TOC interventions contributed to a significant reduction in preventable drug-related (N = 2) and cardiac-related healthcare utilisation (N = 1), a significant reduction in preventable adverse drug events (ADEs) (Odds ratio (OR) 0.34, 95% CI: 0.13-0.94) and an improvement in medication adherence. However, all-cause hospitalisation and medication discrepancies were not significantly reduced. Conclusion: Pharmacy-supported TOC interventions may improve patient outcomes in the MENA region. However, considering the limited quality of evidence and the variability in intervention delivery, future well-designed clinical trials are needed.

Characteristics and outcomes of adult patients with asthma presenting with COVID-19: A comparative cohort study.

BACKGROUND: Bronchial asthma affects about 20% of Qatar's population. The impact of asthma on COVID-19 outcomes is controversial. The aim of this study was to explore the impact of asthma on COVID-19 outcomes and the predictors of COVID-19-related morbidity and mortality in a cohort of asthma patients infected by COVID-19. METHODS: This is a retrospective cohort study of adult patients with asthma infected with COVID-19, who were recruited from Hamad Medical Corporation (HMC), the main healthcare system in Qatar. Patients were matched to a control group of non-asthmatic COVID-19 patients (1:2) based on sex, age, and other comorbidities. RESULTS: Between March and August 2020, 616 patients with asthma met the inclusion criteria. The need for hospitalization among patients with asthma was independently associated with older age (adjusted odds ratio [aOR] for 10 years, 1.32; 95% confidence interval [CI], 1.13-1.54; p = 0.001) and hypertension (aOR, 2.4; 95% CI, 1.43-3.93; p = 0.001) but not with the use of inhaled corticosteroids (ICS), long-acting beta2 agonists, montelukast, or tiotropium. Patients with asthma required less hospitalization for COVID-19 than non-asthmatic patients (28.2% vs. 37.3%, respectively; aOR, 0.59; 95% CI, 0.77-0.90; p < 0.001). However, admission to the intensive care unit (ICU) was comparable between both groups (3.3% vs. 2.2%; aOR, 1.64; 95% CI, 0.78-3.43; p = 0.193). No difference in mortality rate was observed between the two groups. CONCLUSIONS: In Qatar, adult patients with asthma do not appear to be at higher risk of COVID-19-related hospitalization or ICU admission compared to the general adult COVID-19-infected population. Older age and hypertension were the only significant predictors of COVID-19-related hospitalization among patients with asthma. Further larger studies are required to confirm such an association.

Efficacy and safety of insulin glargine 300 units/mL vs insulin degludec in patients with type 1 and type 2 diabetes: a systematic review and meta-analysis.

Background: Ultra-long-acting insulin analogs [insulin degludec (IDeg) and insulin glargine 300 units/mL (IGla-300)] offer a longer duration of action with less risk of hypoglycemia compared to other long-acting insulins. However, data about the comparative efficacy and safety are inconsistent. Methods: We searched CENTRAL, PubMed, Embase, ICTRP Search Portal, and ClinicalTrials.gov on 7 October 2022. Randomized controlled trials (RCTs) comparing the safety and efficacy of IDeg (100 or 200 units/mL) and IGla-300 in patients with type 1 or type 2 diabetes were included. Three review authors independently selected trials, assessed the risk of bias, extracted data, and evaluated the overall certainty of the evidence using GRADE. The primary outcomes were the change in glycated hemoglobin (HbA1c) and any hypoglycemia; the secondary outcomes were the change in fasting plasma glucose (FPG) and severe and nocturnal hypoglycemia. Results: Four open-label RCTs were included (2727 participants), 3 parallel and 1 cross-over. Overall, the risk of bias assessment yielded some concern or high risk. There was a comparable change in HbA1c from baseline to the end of treatment, a mean difference of 0.07% (95% confidence interval (CI) 0.06 - 0.19; p = 0.29; 3 trials; 2652 patients; very low-certainty evidence), and a comparable rate of any hypoglycemia, rate ratio 1.02 (95% CI 0.8 - 1.3; p = 0.87; 3 trials; 2881 patients; very low-certainty evidence). IDeg resulted in more reduction in FPG compared to IGla-300, mean difference of 10.27 mg/dL (95% CI 7.25 - 13.29; p < 0.001; 3 trials; 2668 patients; low-certainty evidence). Similar rates of nocturnal and severe hypoglycemia were observed, rate ratio of 1.13 (95% CI 0.72 - 1.78; p = 0.54; 3 trials; 2668 patients; very low-certainty evidence) and 1.4 (95% CI 0.41 - 4.73; p = 0.59; 2 trials; 1952 patients; very low-certainty evidence), respectively. Conclusion: There is no evidence of a difference between IDeg and IGla-300 in the mean change in HbA1c and the risk of anytime, nocturnal, and severe hypoglycemia. IDeg appeared to cause a higher reduction in FPG compared to IGla-300. However, this finding should be interpreted with caution due to the small number of trials included and their high risk of bias.

Perspectives of clinical pharmacists on the provision of pharmaceutical care through telepharmacy services during COVID-19 pandemic in Qatar: A focus group.

BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic created unprecedented pressures on healthcare systems and led to the widespread adoption of telepharmacy services, a practice that was not previously established in the state of Qatar. OBJECTIVE: The -study aimed to explore clinical pharmacists' (CPs) perspectives and experiences in utilizing telepharmacy for the provision of pharmaceutical care during the COVID-19 pandemic. METHODS: A descriptive, qualitative approach using face-to-face focus group (FG) discussions was used. CPs across Hamad Medical Corporation (HMC) were purposively invited to participate in the study. FG discussions were audio-recorded, transcribed verbatim, and validated. Transcripts were analyzed using inductive thematic analysis. Recruitment continued until a saturation point was achieved. RESULTS: We conducted five focus groups that included 23 CPs and led to seven themes. Overall, CPs reported inadequate preparedness for the practice of telepharmacy, which they perceived as challenging. The primary perceived benefits of telepharmacy were decreased infection exposure risk, improved quality of care, improved patients' satisfaction, and enhanced workplace efficiency and productivity. The main highlighted risks of telepharmacy were related to threatened patient confidentiality, missed pharmaceutical care opportunities, and negatively impacted professional rapport with other healthcare providers; and the major perceived challenges were low digital health literacy, complex illnesses and medication regimens, lack of standardized protocols, and inadequacy of resources and cultural resistance for virtual care. Participants recommended standardization and training, resource allocation, and proper service promotion as potential facilitators of telepharmacy practice. CONCLUSION: The current study revealed that despite perceived barriers, pharmacists identified several benefits of telepharmacy and recommended potential facilitators that should be used to integrate and sustain the practice of telepharmacy in the future. Future studies should investigate the impact of telepharmacy on clinical pharmacy interventions and patient outcomes.

Drive-up INR testing and phone-based consultations service during COVID-19 pandemic in a pharmacist-lead anticoagulation clinic in Qatar: Monitoring, clinical, resource utilization, and patient- oriented outcomes.

Background: Coronavirus disease 2019 (COVID-19) pandemic has resulted in unprecedented pressure on healthcare systems and led to widespread utilization of telemedicine or telehealth services. Combined with teleclinics, using drive-up fingerstick International normalized ratio (INR) testing was recommended to decrease exposure risk of anticoagulation patients. Objective: To evaluate the impact of transitioning from clinic-based anticoagulation management services to drive-up and phone-based services during COVID-19 pandemic in Qatar. Methods: The study comprised of two components: a retrospective cohort study of all eligible patients who attended anticoagulation clinic over 1-year period (6 months before and 6 months after service transition) and a cross-sectional survey of eligible patients who agreed to provide data about their satisfaction with the new service. Monitoring parameters, clinical outcomes, and resource utilization related to warfarin therapy were compared before and after service transition. Patients' experience was explored through a structured survey. Results: There was no statistically significant difference between clinic-based and phone-based anticoagulation services in mean time and number of visits within therapeutic range (P = .67; P = .06 respectively); mean number of extreme subtherapeutic and supratherapeutic INR values (P = .32 and P = .34, respectively); incidence of thromboembolic complications and warfarin related hospitalization. There was one reported bleeding and one emergency visit (0.9%) in the phone-based group vs none in the clinic-based group. Frequency of INR testing and compliance to attending clinics appointments declined significantly (P = .002; P = .001, respectively). Overall, patients were highly satisfied with the new service. The majority of patients found it better (51.6%) or just as good as the traditional service (44.5%). Patients who preferred the new service were significantly younger than their counterparts (P = .005). Conclusion: The service of drive-up INR testing and phone-based consultations was shown to be comparable to traditional anticoagulation service, a finding that supports maintaining such services as part of the new normal after the pandemic is over.

Anticoagulation clinic drive-up service during COVID-19 pandemic in Qatar.

Coronavirus Disease 2019 (COVID-19) is a pandemic affecting many countries worldwide. Given the increasing incidence especially in elderly and individuals with comorbid conditions, it is advised by health authorities to stay home if possible, maintain social distancing and stay away from those who are sick or could be infected. Patients with comorbidities especially cardiovascular disease are at higher risk of getting infected with COVID-19 and have worse prognosis. Among efforts to safely manage warfarin patients during this pandemic, we introduced a hospital drive-up anticoagulation testing service. This service can reduce the risk of exposure of anticoagulation patients to COVID-19 by reducing the contact time with the different personnel at the hospital and by maintaining those patients at a safe distance from others.

Evaluation of the Validity of SAMe-TT2R2 Score in a Cohort of Venous Thromboembolism Patients Treated With Warfarin.

Low SAMe-TT2R2 score of <2 was validated as a predictor of optimum anticoagulation control, reflected by mean time in therapeutic range (TTR) above 65% to 70%, among warfarin-treated atrial fibrillation patients. This study aimed to validate the ability of SAMe-TT2R2 score and its individual components in predicting anticoagulation control (mean TTR and clinical events) among a cohort of venous thromboembolism (VTE) patients in Qatar. A total of 295 patients were retrospectively evaluated. There was a trend toward statistical significance in mean TTR between low (<2) and high (≥ 2) SAMe-TT2R2 score groups (P = .05), a difference that was not sustained when a cutoff of 3 was used (ie, a score of 3 or more). Patients with poor INR control (TTR <70%) were numerically less likely to have SAMe-TT2R2 score of <2 compared with those with good INR control, though the difference was not statistically significant (16.7% vs 83.3%, respectively, P = .4). No thromboembolic events were reported, and no association was found between the score and risk of bleeding. Non-Caucasian origin was the only significant predictor of good anticoagulation in the studied cohort. In conclusion, SAMe-TT2R2 score could not predict quality of anticoagulation control in a cohort of VTE patients treated with warfarin in Qatar. Contribution of other clinical factors and whether a different scoring may yield better prediction of anticoagulation control remains to be tested.

Prevalence and predictors of potentially inappropriate medications among home care elderly patients in Qatar.

BACKGROUND: Older patients receiving home health care are particularly at risk of receiving potentially inappropriate medications compared to community-dwelling population. Data on appropriateness of prescribing in these patients is limited. OBJECTIVE: To investigate the prevalence, patterns and determinants of potentially inappropriate medications among elderly patients receiving Home Health Care Services in Qatar. SETTING: Home Health Care Services department in Hamad Medical Corporation-Qatar. METHODS: A cross-sectional study, conducted over a 3 months period. Patients 65 years and older, taking at least one medication and receiving home care services were included. Potentially inappropriate medications were identified and classified in accordance with the American Geriatrics Society 2012 Beers Criteria. MAIN OUTCOME MEASURE: Prevalence of potentially inappropriate medications using updated Beers criteria. RESULTS: A total of 191 patients (38.2%) had at least one potentially inappropriate medication. As per Beers criteria, 35% of medications were classified as medications to be avoided in older adults regardless of conditions and 9% as potentially inappropriate medications when used with certain diseases or syndromes. The majority of potentially inappropriate medications (56%) were classified as medications to be used with caution. The two leading classes of potentially inappropriate medications were antipsychotics (27.4%) and selective serotonin reuptake inhibitors (16%). Significant predictors of inappropriate prescribing were hypertension [adjusted OR 1.7; 95% CI (1.0, 2.8)], dementia [adjusted OR 2.0; 95% CI (1.2, 3.1)], depression [adjusted OR 21.6; 95% CI (2.8, 168.4)], and taking more than ten prescribed medications [adjusted OR 1.9; 95% CI (1.3, 2.8)]. CONCLUSION: Prescribing potentially inappropriate medications is common among older adults receiving home health care services in Qatar, a finding that warrants further attention. Polypharmacy, hypertension, depression and dementia were significantly associated with potentially inappropriate prescribing.
