ObjectivesTo explore knowledge and attitude of pharmacists in Qatar towards natural health products (NHPs).MethodsThe quantitative component of this study consisted of an anonymous, online, self-administered questionnaire to assess knowledge about NHPs among pharmacists in Qatar. Descriptive statistics and inferential analysis were conducted using Statistical Package of Social Sciences (SPSS®). Means and standard deviation were used to analyze descriptive data, and statistical significance was expressed as P-value, where P≤0.05 was considered statistically significant. Associations between variables were measured using Pearson correlation. The qualitative component utilized focus group (FG) meetings with a purposive sample of community pharmacists. Meetings were conducted until a point of saturation was reached. FG discussions were audio-taped and transcribed verbatim. Data were analyzed using a framework approach to sort the data according to emerging themes.ResultsThe majority of participants had average to poor knowledge about NHPs while only around 7% had good knowledge. In the FG meetings, participants considered the media, medical representatives, and old systems of natural health as major source of their knowledge. They criticized undergraduate pharmacy courses (for inadequately preparing pharmacists to deal with NHPs) and the pharmacy regulations (for being irrelevant). A perception of NHPs as being “safe” still exists among pharmacists.ConclusionsPharmacists’ ability to provide effective services associated with NHPs is limited by poor access to evidence-based information and poor knowledge. A perception of NHPs and CAM as ‘safe’ still exists among pharmacists, and regulations related to NHPs require addressing to follow best practice and ensure patient safety.

Background Digoxin is a cardiac glycoside that is recommended by clinical practice guidelines to be used in patients with heart failure with reduced ejection fraction (HFrEF) who still have persistent symptoms despite optimal medical therapy. However, this recommendation is based on limited and old trial data. Moreover, pharmacoepidemiologic studies are important in determining the prevalence of digoxin use and factors influencing this. Objective This study aimed to determine the prevalence and the predictors of digoxin utilization among patients with HFrEF with or without atrial fibrillation (AF) in Qatar. Setting Heart Hospital, a specialized tertiary care center in Qatar. Methods A retrospective observational study was conducted using Cerner electronic medical records. Subjects included 736 patients admitted between January 1, 2013 and December 31, 2014 with the diagnosis of HFrEF with or without AF. Two groups of patients were studied: digoxin users and digoxin non-users at index hospitalization until discharge. Univariate and multivariate binary logistic regression analyses were conducted to determine the predictors of digoxin prescription. Data analyses were performed using IBM SPSS version 23.0. Main outcome measures Prevalence and predictors of digoxin prescriptions among HFrEF patients measured in percentages and odds rations, respectively. Results A total of 736 patients who met the inclusion criteria were analyzed for digoxin prevalence, including 80 patients (11%) who were newly prescribed digoxin during the index hospitalization. After adjusting for patient demographics and clinical characteristics, the use of thiazide diuretics (aOR = 10.14, CI 2.31-44.6, p value = 0.002), concurrent AF (aOR = 8.2, CI 3.11-21.7, p < 0.001), and an ejection fraction (EF) <25% (aOR = 3.2, CI 1.5-6.8, p value = 0.002) significantly predicted digoxin prescriptions among patients with HFrEF. Conclusion The rate of digoxin prescription among patients with HFrEF in Qatar is relatively low. The strongest predictors of digoxin use in HFrEF patients were the concomitant use of thiazide diuretics and concurrent diagnosis of AF. The findings may potentially serve as useful guides for the rational utilization of digoxin in patients with HFrEF.
