Greek Physicians' Perceptions on Generic Drugs in the Era of Austerity.

ABSTRACT: Purpose. To assess the beliefs and preferences of Greek physicians, regarding generic drugs, in the years of financial crisis. Setting. Multicentered, nationwide survey. Material and Methods. A custom questionnaire based on former similar studies was developed and administered to Greek physicians. The variable "perception on generics" was constructed after an exploratory study and the instrument was validated by conventional and Rasch analysis methods. 22 items formed 5 subscales that constructed the variable in question. Results. 908 physicians successfully participated in the study (response rate: 80%). Mean total scores to the instrument were 60.63 ± 12.12 for men and significantly less (58.24 ± 11.73) for women (p = 0.04). Greek physicians were not persuaded on the potential economic gain (45.79 ± 10.53); moreover they identified that Greek authorities cannot address the increased pharmacovigilance mandates. Physicians working in Athens and those working in surgical units demonstrated significantly worse scores than their colleagues from the rest of Greece and those working in Internal Medicine wards (p = 0.03).??Conclusion. Our results suggest an overall poor acceptance of the national initiative on generic drugs by Greek physicians. This trial is registered with Clinicaltrials.gov identifier: NCT01855802.

Project description:Aims:This study aims to (i) translate, culturally adapt, and validate the Jefferson Scale of Patient Perception of Physician Empathy questionnaire for the Greek population (Gr-JSPPPE) and (ii) estimate physicians' self-assessed empathy and patients' perceptions of physicians' empathy, investigate their relationship, and assess their predictors. Methods:A total of 189 patients and 17 physicians from an internal medicine clinic took part in the study. A composite questionnaire was administered to the patients, consisting of (1) sociodemographic items, (2) hospitalization-related questions, (3) the Zung Self-Rating Anxiety Scale, (4) the Patient Health Questionnaire (PHQ-9), (5) the EQ-5D-5L Questionnaire, (6) the Gr-JSPPPE, and (7) the Visual Analog Scale for pain. The physicians' composite questionnaire comprised (1) sociodemographic items, (2) the EQ-5D-5L questionnaire, and (3) the Toronto Composite Empathy Scale (TCES). Exploratory and confirmatory factor analyses were conducted to assess the psychometric properties of the Gr-JS PPPE. Univariate comparisons were performed between (a) empathy measures and (b) sociodemographic and health-related measures of both groups; multivariate regression analysis for the Gr-JSPPPE adjusting for baseline confounders was executed. Results:Statistically significant negative correlations were found between the Gr-JSPPPE mean score and the TCES personal/cognitive, professional/cognitive, and professional/emotional subscales. Female sex, being married, duration of employment in current post, and physicians' EQ-5D index score emerged as important predictors of increased physician empathy. Patients' EQ-VAS "thermometer" scale was significantly associated with the Gr-JSPPPE total score at the multivariate level. Conclusion:The Gr-JSPPPE is a psychometrically sound tool to assess patient perceptions of physician empathy. Physician empathy assessed by the self-reported scale is inversely associated with patient perceptions.

Project description:Background Generic medicines substitution is an important means to control rapid growth of pharmaceutical expenditures for the healthcare system in China. Acceptance and utilization of generic medicines is highly influenced by healthcare providers’ perceptions. This study aimed to compare the knowledge, awareness and perceptions of generic medicines between physicians and pharmacists in China. Methods We used an online, cross-sectional survey across China. The questionnaire explored four sections: demographic characteristics, assessment of the participants’ knowledge and awareness of generic medicines, perceptions of generic medicines and generic substitution practices. Chi-square or Mann–Whitney-U tests were applied to compare differences between physicians and pharmacists. P-values < 0.05 were considered significant. Results A total of 1644 physicians and 4187 pharmacists participated. Most physicians (82.8%, n = 1362) and pharmacists (89.8%, n = 3760) correctly identified the definition of generic medicines. A similar percentage of physicians and pharmacists agreed that approved generic medicines are as effective (64.1% vs 68.2%) or safe (63.8% vs 69.1%) as brand-name medicines. Most physicians and pharmacists (67.6% vs 71.0%) supported the policy of generic substitution. In practice, 79.4% (n = 1305) of physicians reported that they had prescribed generic medicines. More than 78% of respondents reported an obvious increase in the number of generic medicines prescribed in their medical institutions. The majority of physicians and pharmacists identified lack of trust regarding efficacy and safety of generic medicines and the difficulty of changing patients’ preference as top challenges in generic substitution. Conclusions Both physicians and pharmacists surveyed had adequate knowledge of generic medicines, and hold positive attitude towards generics and generic substitution. Efficacy and safety are key factors related to prescribing or dispensing generic medicines. Various policies and regulations should be taken to encourage successful generic substitution.

Project description:BackgroundGeneric drugs and generic substitution belong to the tools by which healthcare costs may be reduced. However, low awareness and reluctance among healthcare professionals towards generic drugs may negatively affect the rational use of generic substitution.MethodsThe study aimed to analyze opinions and attitudes towards generic drugs and generic substitution among Czech physicians including their understanding of generic substitution legislative rules and the physicians´ previous experience in this field. Using random allocation, 1551 physicians practicing in the Czech Republic were asked to participate in the sociological representative survey conducted from November to December 2016, through face-to-face structured interviews comprising 19 items. Factor analysis as well as reliability analysis of items focused on legal rules in the context of physicians' awareness were applied with p-value of <?0.05 as statistically significant.ResultsOf a total of 1237 (79.8%) physicians (43.7% males; mean age 47.5?±?11.6?years, 46.3% general practitioners) 24.8% considered generic drugs to be less safe, especially those with specialized qualification (p <?0.01). However, only 4.4% of the physicians noticed any drug-related problems, including adverse drug reactions associated with generic substitution. The majority of physicians felt neutrally about performing generic substitution in pharmacies, nor they expressed any opinion on characteristics of generics, even though a better understanding of the legislation and higher need of accordance of substituted drugs were associated with more positive attitudes towards generic substitution (p <?0.05). Physicians showed low knowledge score of legislative rules (mean 3.9?±?1.6 from maximum 9), nevertheless they overestimated the law, as they considered some rules valid, even if the law does not require them. Cronbach alpha of all legislative rules that regulate generic substitution increased from 0.318 to 0.553 if two optional rules (physician consent and strength equivalence) would be taken into account.ConclusionsThere is no sufficient awareness of generic drugs and generic substitution related issues among Czech physicians, although a deeper knowledge of legislation improves their perception about providing generic substitution.

Project description:BackgroundOver 84 % of all prescriptions in the US are filled as generic drugs, though in prior surveys, patients reported concerns about their quality.ObjectiveWe aimed to survey patients' perceptions and use of generic drugs.DesignOur survey (administered August 2014) assessed patients' skepticism about generic drug safety and effectiveness and how often they requested brand-name drugs. Chi-square tests and two-sample t-tests assessed associations between patient demographics and the outcomes.ParticipantsOur sample frame was the CVS Advisor Panel, a national database of 124,621 CVS customers. We randomly selected 1450 patients with self-reported chronic conditions who filled at least one prescription in the prior 3 months.Main measuresWe assessed how often patients reported asking their physicians to prescribe a brand-name over a generic drug in the last year, and "generic skepticism," defined as not believing generic drugs were as safe, effective, had the same side effects, and contained the same active ingredients as brand-name drugs.Key resultsOf the 1,442 patients with valid addresses, 933 responded (65 % response rate) and 753 took the full survey. A vast majority (83 %) agreed that physicians should prescribe generic drugs when available, and 54 % said they had not asked their physicians to prescribe a brand-name drug over a generic in the past year. Most respondents considered generic drugs to be as effective (87 %) and safe (88 %) as their brand-name counterparts, and to have the same side effects (80 %) and active ingredients (84 %). Non-Caucasians were more likely than Caucasians to request a brand-name drug over a generic (56 % vs. 43 %, p?<?0.01), and were also more skeptical of generic drugs' clinical equivalence (43 % vs. 29 %, p?<?0.01).ConclusionsWe found a substantial shift towards more patients having positive views of generic drugs, but lingering negative perceptions will have to be overcome to ensure continued cost-savings and improved patient outcomes from generic drugs.

Project description:The extents of generic-reference and generic-generic average bioequivalence and intra-subject variation of on-market drug products have not been prospectively studied on a large scale.We assessed bioequivalence of 42 generic products of 14 immediate-release oral drugs with the highest number of generic products on the Saudi market. We conducted 14 four-sequence, randomized, crossover studies on the reference and three randomly-selected generic products of amlodipine, amoxicillin, atenolol, cephalexin, ciprofloxacin, clarithromycin, diclofenac, ibuprofen, fluconazole, metformin, metronidazole, paracetamol, omeprazole, and ranitidine. Geometric mean ratios of maximum concentration (Cmax) and area-under-the-concentration-time-curve, to last measured concentration (AUCT), extrapolated to infinity (AUCI), or truncated to Cmax time of reference product (AUCReftmax) were calculated using non-compartmental method and their 90% confidence intervals (CI) were compared to the 80.00%-125.00% bioequivalence range. Percentages of individual ratios falling outside the ±25% range were also determined.Mean (SD) age and body-mass-index of 700 healthy volunteers (28-80/study) were 32.2 (6.2) years and 24.4 (3.2) kg/m2, respectively. In 42 generic-reference comparisons, 100% of AUCT and AUCI CIs showed bioequivalence, 9.5% of Cmax CIs barely failed to show bioequivalence, and 66.7% of AUCReftmax CIs failed to show bioequivalence/showed bioinequivalence. Adjusting for 6 comparisons, 2.4% of AUCT and AUCI CIs and 21.4% of Cmax CIs failed to show bioequivalence. In 42 generic-generic comparisons, 2.4% of AUCT, AUCI, and Cmax CIs failed to show bioequivalence, and 66.7% of AUCReftmax CIs failed to show bioequivalence/showed bioinequivalence. Adjusting for 6 comparisons, 2.4% of AUCT and AUCI CIs and 14.3% of Cmax CIs failed to show bioequivalence. Average geometric mean ratio deviation from 100% was ?3.2 and ?5.4 percentage points for AUCI and Cmax, respectively, in both generic-reference and generic-generic comparisons. Individual generic/reference and generic/generic ratios, respectively, were within the ±25% range in >75% of individuals in 79% and 71% of the 14 drugs for AUCT and 36% and 29% for Cmax.On-market generic drug products continue to be reference-bioequivalent and are bioequivalent to each other based on AUCT, AUCI, and Cmax but not AUCReftmax. Average deviation of geometric mean ratios and intra-subject variations are similar between reference-generic and generic-generic comparisons.ClinicalTrials.gov identifier: NCT01344070 (registered April 3, 2011).
