Adherence as a Predictor of Glycemic Control Among Adolescents With Type 1 Diabetes: A Retrospective Study Using Real-world Evidence.

PURPOSE: Metabolic control among adolescents with type 1 diabetes mellitus (T1DM) is generally poor. Nonadherence is a contributor to this poor glycemic control, leading to adverse outcomes. The findings of studies reporting the association between adherence and glycemic control are conflicting. This study aimed to assess the level of adherence among adolescents with T1DM and its relationship with glycemic control. METHODS: This was a retrospective, cross-sectional study that was conducted at Sidra Medicine, a state-of-the-art tertiary health care facility for women and children in Qatar. Mean blood or interstitial glucose monitoring frequency (BGMF) was used to assess adherence level among adolescents with T1DM, whereas glycemic control was assessed via documented glycated hemoglobin A1c (HbA1c). Adolescents who had a mean BGMF of ≥4 checks per day were considered adherent, and those who had an HbA1c level of <7% were considered as having controlled diabetes. Correlational and logistic regression analyses were performed to assess the relationship between adherence and glycemic control, incorporating other covariates into the model. FINDINGS: The rate of adherence among adolescents with T1DM in Qatar was 40.9%. Adherent adolescents had significantly lower median HbA1c levels compared with nonadherent adolescents (9.0% vs. 9.7%; P = 0.002). A significant negative correlation was found between BGMF and HbA1c level (correlation coefficient rs = -0.325; P < .001). Approximately 97% of nonadherent adolescents compared with 87% of adherent adolescents had suboptimal diabetes control (HbA1c ≥7%) (P = .016). Furthermore, nonadherent adolescents were 78% less likely to have controlled diabetes compared with adherent adolescents (adjusted odds ratio = 0.221; 95% CI, 0.063-0.778; P = 0.019). The combined effect of the determinants of glycemic control among adolescents with T1DM that were included in the multiple regression model was able to explain approximately 9% of the variances in glycemic control (Cox and Snell R2 = 0.092). IMPLICATIONS: The current findings suggest that nonadherence was highly prevalent among adolescents with T1DM and was a significant independent predictor of glycemic control, explaining 9% of the variability. This finding warrants further exploration of other possible predictors of poor glycemic control among the adolescent population. Comprehensive interventions, including educational, technological, and health service delivery aspects, aimed at improving adherence and ultimately optimizing glycemic control are warranted in adolescents with T1DM.

Determination of potential drug-drug interactions in prescription orders dispensed in a community pharmacy setting using Micromedex® and Lexicomp®: a retrospective observational study.

Background Community pharmacists have a role in identifying drug-drug interactions (DDIs) when processing prescription orders and dispensing medications to patients. The harmful effects of DDIs can be prevented or minimized by using an electronic DDI checker to screen for potential DDIs (pDDIs). However, different DDI checkers have variable rates of detecting pDDIs. Aim To estimate the prevalence of pDDIs in prescriptions dispensed in a community pharmacy setting using two electronic DDI databases and to evaluate the association between the pDDIs and contributory factors. Method Eligible prescription orders dispensed by a community pharmacy chain in Qatar from January to July 2020 were included in this retrospective observational study. For each prescription, Micromedex® and Lexicomp® were simultaneously used to identify pDDIs, and the interactions categorized based on severity and risk rating. Results Seven hundred-twenty prescriptions met the inclusion criteria, of which Micromedex® and Lexicomp® respectively identified 125 prescriptions (17.4%) and 230 prescriptions (31.9%) as having at least one pDDI. Moderate strength of agreement was found between Lexicomp® and Micromedex® in identifying pDDIs (Cohen's Kappa = 0.546). Micromedex® classified 61.6% of DDIs as major severity, while Lexicomp® classified 30.8% as major severity. The number of concurrent medications per prescription was significantly and positively associated with pDDI. Conclusion This study demonstrates a high prevalence of pDDIs among prescriptions dispensed in a community pharmacy setting. It is advisable that community pharmacists in Qatar, who typically do not have access to computerized patient profiles, use these DDI checkers to ensure all pDDIs are communicated to respective prescribers for appropriate action.

Evaluation of patient safety culture in community pharmacies in Qatar.

INTRODUCTION: Patient safety culture is a key contributor to medication safety globally. However, the perspective of pharmacists and other personnel in community pharmacy regarding patient safety culture may vary from one country to another. OBJECTIVE: The aim of this study was to determine the perspectives of community pharmacy personnel in Qatar about patient safety culture in community pharmacy setting. METHODS: A cross-sectional web-based survey utilising the Agency for Healthcare Research and Quality Community Pharmacy Survey on Patient Safety Culture was conducted. Participants included community pharmacy personnel practicing in Qatar. Both descriptive and inferential statistics were applied for data analyses, with statistical significance set at ≤ 0.05. RESULTS: Two hundred and forty participants completed the survey. A large proportion of the respondents (52.5%) reported an "excellent" overall rating of patient safety in their respective community pharmacies. Patient counselling and teamwork composites of patient safety culture were associated with the highest positive responses (95% and 93.7%, respectively). The "staffing, work pressure and pace" composite demonstrated the lowest positive response (50.6%) among the 11 composites. Inferential analysis revealed that working in chain pharmacies was significantly associated with positive responses related to "teamwork" (P = .019). Furthermore, working for more than 40 hours per week had a significant positive influence on the overall perceptions of patient safety (P = .025). CONCLUSION: There was an overall positive perception towards patient safety culture among the surveyed community pharmacy personnel in Qatar. Superiority was observed with patient counselling and teamwork, while staffing, work pressure and pace were judged poorly, warranting further investigations and potential targeting for interventions.

Progress in the discovery of treatments for C. difficile infection: A clinical and medicinal chemistry review.

Clostridium difficile is an anaerobic, Gram-positive pathogen that causes C. difficile infection, which results in significant morbidity and mortality. The incidence of C. difficile infection in developed countries has become increasingly high due to the emergence of newer epidemic strains, a growing elderly population, extensive use of broad spectrum antibiotics, and limited therapies for this diarrheal disease. Because treatment options currently available for C. difficile infection have some drawbacks, including cost, promotion of resistance, and selectivity problems, new agents are urgently needed to address these challenges. This review article focuses on two parts: the first part summarizes current clinical treatment strategies and agents under clinical development for C. difficile infection; the second part reviews newly reported anti-difficile agents that have been evaluated or reevaluated in the last five years and are in the early stages of drug discovery and development. Antibiotics are divided into natural product inspired and synthetic small molecule compounds that may have the potential to be more efficacious than currently approved treatments. This includes potency, selectivity, reduced cytotoxicity, and novel modes of action to prevent resistance.
