Evaluation of the prescribing practice of guideline-directed medical therapy among ambulatory chronic heart failure patients.

BACKGROUND: Studies have demonstrated that heart failure (HF) patients who receive direct pharmacist input as part of multidisciplinary care have better clinical outcomes. This study evaluated/compared the difference in prescribing practices of guideline-directed medical therapy (GDMT) for chronic HF patients between two multidisciplinary clinics-with and without the direct involvement of a pharmacist. METHODS: A retrospective audit of chronic HF patients, presenting to two multidisciplinary outpatient clinics between March 2005 and January 2017, was performed; a Multidisciplinary Ambulatory Consulting Service (MACS) with an integrated pharmacist model of care and a General Cardiology Heart Failure Service (GCHFS) clinic, without the active involvement of a pharmacist. RESULTS: MACS clinic patients were significantly older (80 vs. 73 years, p < .001), more likely to be female (p < .001), and had significantly higher systolic (123 vs. 112 mmHg, p < .001) and diastolic (67 vs. 60 mmHg, p < .05) blood pressures compared to the GCHF clinic patients. Moreover, the MACS clinic patients showed more polypharmacy and higher prevalence of multiple comorbidities. Both clinics had similar prescribing rates of GDMT and achieved maximal tolerated doses of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in HFrEF. However, HFpEF patients in the MACS clinic were significantly more likely to be prescribed ACEIs/ARBs (70.5% vs. 56.2%, p = 0.0314) than the GCHFS patients. Patients with both HFrEF and HFpEF (MACS clinic) were significantly less likely to be prescribed ß-blockers and mineralocorticoid receptor antagonists. Use of digoxin in chronic atrial fibrillation (AF) in MACS clinic was significantly higher in HFrEF patients (82.5% vs. 58.5%, p = 0.004), but the number of people anticoagulated in presence of AF (27.1% vs. 48.0%, p = 0.002) and prescribed diuretics (84.0% vs. 94.5%, p = 0.022) were significantly lower in HFpEF patients attending the MACS clinic. Age, heart rate, systolic blood pressure (SBP), anemia, chronic renal failure, and other comorbidities were the main significant predictors of utilization of GDMT in a multivariate binary logistic regression. CONCLUSIONS: Lower prescription rates of some medications in the pharmacist-involved multidisciplinary team were found. Careful consideration of demographic and clinical characteristics, contraindications for use of medications, polypharmacy, and underlying comorbidities is necessary to achieve best practice.

Person-centered, non-pharmacological intervention in reducing psychotropic medications use among residents with dementia in Australian rural aged care homes.

BACKGROUND: High rates of psychotropic medications are prescribed in aged care homes despite their limited effectiveness and associated adverse effects. We aim to evaluate the changes in prescription patterns for elderly residents with dementia in the 'Harmony in the Bush Dementia Study'. Harmony in the Bush is a person-centered model of dementia care in nursing homes, based on the principles of Progressively Lowered Stress Threshold and person-centered music intervention. METHODS: Our larger study (12 weeks period) was a quasi-experimental design conducted in five rural nursing homes in Australia. Medication charts (n = 31) were collected retrospectively from three rural aged care facilities. Medication data for each resident was collected from a three-month medication charts, pre-intervention, and post-intervention. Fifty-three staff participated in 31 semi-structured interviews and 8 focus groups at post-intervention, and at 1-month and 3-months follow up. RESULTS: The median age of the participants was 83 years, and 68% of them were female. Polypharmacy was measured in 87% (n = 27) of the participants. Hypertension, hyperlipidemia, diabetes, and the Alzheimer's disease were the major comorbidities identified in residents. None of the residents received more than the maximum dose of psychotropic medications recommended by the guidelines. There was a reduction of 22.4% (77.4% vs 55%) in the use of at least any psychotropic medications, 19.6% (39% vs, 19.4%) reduction in antipsychotics and benzodiazepines (39% vs 19.4%), and 6.5% (42% vs 35.5%) reduction in antidepressants prescription medicines, when comparing residents' medication charts data covering 3-months pre- and post-intervention, however, these changes were not statistically significant. Additionally, there was a decreasing trend in the use of inappropriate medications. Psychotropic medications were prescribed in up to 43% and anti-dementia medications in 44% of participants for more than 6 months. Three themes extracted from qualitative data include decrease behavioral and psychiatric symptoms of dementia due to medication weaning or dose tapering, other strategies to reduce medication use, and environmental or noise control. CONCLUSIONS: Our findings indicate that the Harmony in the Bush model as a non-pharmacological approach reduces the prescription of psychotropic medications in rural nursing homes as supported by findings from both quantitative and qualitative data.

Effectiveness of the Pharmacist-Involved Multidisciplinary Management of Heart Failure to Improve Hospitalizations and Mortality Rates in 4630 Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: There is evidence that heart failure (HF) patients who receive pharmacist care have better clinical outcomes. METHODS AND RESULTS: English-language peer-reviewed randomized controlled trials comparing the pharmacist-involved multidisciplinary intervention with usual care were included. We searched PubMed, MEDLINE, EMBASE, CINAHL, Web of Science, Scopus, and the Cochrane Library from inception through March 2017. Cochrane method for risk of bias was used to assess within and between studies. 18 RCTs (n = 4630) were included for systematic review, and 16 (n = 4447) for meta-analysis. Meta-analysis showed a significant reduction in HF hospitalizations {odds ratio (OR) 0.72 [95% confidence interval (CI) 0.55-0.93], P = .01, I2  =  39%} but no effect on HF mortality. Similarly, a significant reduction in all-cause hospitalizations [OR 0.76, 95% CI (0.60-0.96), P = .02, I2  =  52%] but no effect on all-cause mortality was revealed. The overall trend was an improvement in medication adherence. There were significant improvements in HF knowledge (P<.05), but no significant improvements were found on health care costs and self-care. CONCLUSIONS: The pharmacist is a vital member of a multidisciplinary team in HF management to improve clinical outcomes. There was a great deal of variability about which specific intervention is most effective in improving clinical outcomes.

Role of the Pharmacist for Improving Self-care and Outcomes in Heart Failure.

PURPOSE OF REVIEW: This review highlights the current and emerging approaches for the role of the pharmacist for improving self-care and outcomes in heart failure management. RECENT FINDINGS: Pharmacists are contributing to heart failure management in a variety of settings, including hospitals, clinics, and communities. Different interventions which may be mediated by the pharmacist include drug adherence, discharge counseling, medication reconciliation, telephone follow-up, and recommendation of evidence-based medicines. Pharmacist engagement in heart failure management has demonstrated improved drug adherence, readmission rates, medication management, self-care ability, patient satisfaction, and heart failure knowledge. Some findings are mixed, especially for readmission rates. Improved medication management was reported in nearly all studies, despite significant heterogeneity in the models of care, patient populations, and study designs. This review highlights the requirement for large randomized trials with extended follow-up to confirm the impact of the role of the pharmacist in HF self-care, particularly through multidisciplinary-based interventions.

PF2401-SF, standardized fraction of Salvia miltiorrhiza, induces apoptosis of activated hepatic stellate cells in vitro and in vivo.

During the course of our attempts to develop a potential herbal medicine, we had previously prepared PF2401-SF, a standardized fraction of S. miltiorrhiza, and reported its hepatoprotective activity in vitro as well as in vivo. Since apoptosis of activated hepatic stellate cells (HSCs) is a well-accepted anti-fibrotic strategy, in this study, we investigated the direct effect of PF2401-SF on t-HSC/Cl-6 cells in vitro and on CCl4-induced liver injury in vivo. We evaluated the activation and cleavage of hallmarkers of apoptosis, namely, caspase 3, 8, 9 and PARP. Upregulation of the pro-apoptotic Bax protein and downregulation of the anti-apoptotic Bcl2 protein were also analyzed. Furthermore, in the PF2401-SF treated rats, apoptosis induction of activated HSCs was demonstrated by reduced distribution of α-SMA-positive cells and the presence of high number of TUNEL-positive cells in vivo. Our data suggest that PF2401-SF can mediate HSCs apoptosis induction, and may be a potential herbal medicine for the treatment of liver fibrosis.

Person-Centred, Culturally Appropriate Music Intervention to Improve Psychological Wellbeing of Residents with Advanced Dementia Living in Australian Rural Residential Aged Care Homes.

This quasi-experimental, nonrandomized intervention study reports the effect of person-centred, culturally appropriate music on psychological wellbeing of residents with advanced dementia in five rural residential aged care homes in Australia. Seventy-four residents attended in person-centred music sessions and culturally appropriate group sessions. Interest, response, initiation, involvement, enjoyment, and general reactions of the residents were assessed using the Music in Dementia Assessment Scale (MiDAS), and interviews and focus groups were conducted with aged care staff and musicians. The overall effect of person-centred sessions at two-time points were: during the intervention-351.2 (SD 93.5); and two-hours post intervention-315.1 (SD 98.5). The residents presented a moderate to high level of interest, response, initiation, involvement, and enjoyment during the session and at post-intervention. However, the MiDAS sub-categories' mean scores differed between the time-points: interest (t59 = 2.8, p = 0.001); response (t59 = 2.9, p = 0.005); initiation (t59 = 2.4, p = 0.019); and involvement (t59 = 2.8, p = 0.007), indicating a significant decline in the effect of person-centred music over time. Interestingly, during the period of time, most of the residents were observed with no exhibitions of agitation (87.5%), low in mood (87.5%), and anxiousness (70.3%), and with a presentation of relaxation (75.5%), attentiveness (56.5%), and smiling (56.9%). Themes from qualitative data collected regarding culturally appropriate group music sessions were behavioural change, meaningful interaction, being initiative, increased participation, and contentment. The findings suggest that the integration of music into care plans may reduce the residents' agitation and improve their emotional wellbeing in rural aged care homes.

Work-related, socio-cultural, and personal factors associated with locus of control among Australian general practitioners.

BACKGROUND: Locus of control (LoC) is a social cognition, that relates to the level of self-control that people have over their personal environment that influences their life. In this context, LoC is frequently associated with work-related behavioral outcomes, ranging from job attitudes, career behaviors, stress, and burnout. OBJECTIVE: To investigate the association between LoC, and work-related behavioral factors, socio-cultural factors, and personal factors among Australian General Practitioners (GPs). METHODS: This study utilized data from the 2010 Medicine in Australia: Balancing Employment and Life (MABEL) survey of doctors. Locus of control (LoC) was measured by a 7-point Likert scale based on Pearlin-Schooler Mastery/Self-efficacy 7-item Scale. Higher score indicated lower internal LoC. Multivariate linear regression model was performed to determine the independent predictors of LoC. RESULTS: Of 3,664 GP participants, LoC did not differ by gender. Poor/fair self-rated health, working in urban location, running a stressful practice, poor balance of professional and personal commitments, poor support network, financial circumstances after retirement, and perception of unrealistic expectation by patients were significant predictors for a lower Internal LoC in a multivariate linear regression model. Adjusted R2 explained 22.4% of variation in predicting the LoC in our models. CONCLUSIONS: LoC of Australian GPs is negatively affected by poor work-life balance, inadequate support, and unrealistic patient expectation. These work-place specific factors could be targeted by interventions to improve GPs wellbeing.

Pharmacy practice in emergency response during the COVID-19 pandemic: Lessons from Australia.

The purpose of this paper is to provide an overview of the pharmacy practice and initiatives taken by the Australian federal government to ensure the continued supply of essential medicines under the conditions of an emergency response plan for COVID-19. During the pandemic, Australian pharmacists have been working collaboratively with multidisciplinary teams at the frontline to manage the equitable and safe supply of medicines despite the unprecedented situation. Although these presented problems for small pharmacies, social distancing policies were implemented widely to maintain personal and environmental hygiene and reduce the number of face-to-face patient visits. In collaboration with various pharmaceutical stakeholders, the Australian government responded rapidly to ensure equitable and sufficient supply with continued access to therapeutic goods during the pandemic. Additionally, vital policies and practices have been implemented, including supplying regular medicines at government-subsidized prices, a maximum one-month supply of some prescription medicines and purchase limits on over-the-counter medicines (one unit per purchase), medication management reviews through telehealth, electronic and digital prescribing, home delivery of medicines to vulnerable people and those in home isolation and the provision of serious shortage medicine substitution rights to pharmacists. Pharmacists were encouraged to communicate and collaborate with other local pharmacies to ensure that essential pharmacy services met community needs (e.g., opening hours). However, there has been a shortage of some medicines due to supply chain disruption and increased demand due to the pandemic. Higher demand for flu vaccinations, increased work pressure in pharmacies, and severe frustration and anxiety in pharmacy customers were also reported. Vigilance is required to monitor foreseeable shortages of therapeutics goods, particularly in regional pharmacies. There is an opportunity for long-term change to retain certain rights and roles based on the competence shown by pharmacists in this challenging period, such as telephone medication reviews, telehealth for MedsCheck and Diabetes MedsCheck, digital prescription handling and therapeutic substitution.

Utilising digital health to improve medication-related quality of care for hypertensive patients: An integrative literature review.

BACKGROUND: Hypertension or high blood pressure is considered as a significant contributor and risk factor to many serious conditions, approximately 1.13 billion people have hypertension globally. However, the integrated technologies can upscale health provisions and improve the effectiveness of the healthcare system. WHO has recommended that the digital health interventions (DHIs) and the Health System Challenges should be used in tandem in addressing health. AIM: To summarise the outcomes from a range of research which investigated the use of DHI to improve the medication-related quality of care (MRQOC) for hypertensive patients. METHODS: An integrative literature review was undertaken in October 2019 using the Medline, Cumulative Index of Nursing and Allied Health Literature, and Scopus databases for publications in English with no date limit. RESULTS: In total, 18433 participants were included in this review from 28 studies meeting the eligibility criteria. There were 19 DHI identified within eight countries: Australia, Canada, India, South Korea, Lebanon, Pakistan, the United Kingdom, and the United States of America. The DHI were provided as community-based, clinical-based and home-based program through mobile phone, mobile health system, short message service, and telehealth, digital medicine, and online healthcare (web-based). The mean age of participants was 59 ranging from 42 to 81 years with an average mean systolic blood pressure of 143.3 mmHg at baseline, ranging from 129.0 mmHg to 159.0 mmHg. The proportion of male participants ranged from 13.9% to 92.0%. Eighteen interventions showed evidence of reduction in blood pressure and improvement of self-management in relation to medication adherence and blood pressure control. The reduction of systolic blood pressure ranged between 1.9 mmHg and 26.0 mmHg, with a mean of 10.8 mmHg. The digital health was found positively associated with the MRQOC for hypertensive patients such as improvement in medication adherence and medication management; better blood pressure control; maintaining follow-ups appointment and self-management; increasing access to healthcare particularly among patients living in rural area; and reducing adverse events. However, some interventions found no significant effect on hypertensive care. The follow up duration varied between 2 mo and 18 mo with an average attrition rate of 10.1%, ranging from 0.0% to 17.4%. CONCLUSION: Utilising digital health innovation for hypertensive care in different settings with tailored interventions positively impacted on MRQOC leading to an improvement of patient outcomes and their quality of life. Nevertheless, inconclusive findings were found in some interventions, and inconsistent outcomes between DHI were noted. A future research and evidence-based DHI for hypertension or chronic diseases should be developed through the evidence-to-decision framework and guidelines.

Undergraduate pharmacy students' attitudes and perceived barriers toward provision of pharmaceutical care: a multi-institutional study in Nepal.

Background: Pharmaceutical care (PC) has a significant impact on optimizing pharmacotherapy and improving patients' quality of life. We aimed to determine the attitudes and perceived barriers of final year pharmacy undergraduates towards provision of PC services in Nepal. Methods: A cross-sectional study was conducted among 232 students using a 13-item-standard PC attitude survey (PCAS) questionnaire and 12-itemed PC barrier questionnaires. Mann-Whitney U test and Kruskal-Wallis tests were used to measure the median difference between groups, at alpha=0.05, and Spearman's rho test was used to measure the strength of the correlation. Results: Majority of students were self-motivated in undertaking the current pharmacy education (178, 76.7%) and had no previous incomplete grades that could delay their graduation (177, 76.3%). Over 80% of students had a positive attitude toward all items of PCAS (agreed and strongly agreed) except for two items. Whereas, 61 (26.3%) disagreed and strongly disagreed that providing PC takes too much time and effort. The major barriers perceived were inadequate PC training (176, 75.9%), inadequate drug information resources in the pharmacy (170, 73.3%), and lack of access to patient medical records in the pharmacy (165, 71.1%). A significant relationship was noticed between positive attitude towards PC and three factors; source of motivation, current employment in pharmacy job, and incomplete grades delaying graduation. Age factor was significant but negatively correlated with the scores of positive attitudes namely "I would like to perform PC as a pharmacist practitioner", "Providing PC is professionally rewarding" and "I feel that the PC is the right direction for the provision to be headed". Conclusion: Nepalese undergraduate pharmacy students had positive attitudes toward PC. Exercising proper pharmacy practice regulations and educational efforts to overcome the perceived barriers may lead to better delivery of PC.

Anti-fibrotic effect of PF2401-SF, a standardized fraction of Salvia miltiorrhiza, in thioacetamide-induced experimental rats liver fibrosis.

We previously reported the in vitro and in vivo hepatoprotective and anti-fibrotic effects of PF2401-SF, a standardized fraction of Salvia miltiorrhiza, against acute and subacute liver injury. The aim of this study was to investigate the effect of PF2401-SF on liver fibrosis induced by thioacetamide (TAA), a chronic liver injury model (12 weeks) that closely resembles fibrosis and cirrhosis in humans. Hepatoprotective activity was indicated by low serum levels of the markers aspartate amino transferase and alanine amino transferase .In addition, compared to the TAA-group livers, the PF2401-SF-treated liver tissues showed no fibrous tissue deposition in the portal areas, hepatocyte morphology more closely resembling normal tissue morphology, and significantly reduced collagen deposition. Furthermore, downregulation of collagen 1(α) and tissue inhibitor of metalloproteinase (TIMP)1 protein and mRNA expression also supports PF2401-SF's anti-fibrotic effect. We also observed reduced expression of α-smooth muscle actin (α-SMA), an important marker of hepatic stellate cells (HSCs) activation. From these results, we conclude that PF2401-SF's anti-fibrotic mechanism in the TAA model involves reduced HSC activation, and may be mediated by downregulation of central markers of fibrosis, including collagen 1(α), TIMP1, and α-SMA.

Apoptotic effect of propyl gallate in activated rat hepatic stellate cells.

Hepatic stellate cells (HSCs) play a central role in liver fibrosis. Inhibition of HSC growth and induction of apoptosis have been proposed as therapeutic strategies for the treatment and prevention of liver fibrosis. Propyl gallate (PG) is an antioxidant widely used in processed foods, cosmetics and medicinal preparations. However, the anti-fibrotic effect of PG in liver injury is unclear. In this study, we investigated whether PG could induce apoptosis in activated HSCs. Treatment of activated HSCs with PG inhibited cell viability in a dose- and time-dependent manner. PG induced apoptosis as demonstrated by morphological changes, poly(ADP-ribose) polymerase (PARP) cleavage, caspase-3 cleavage, increased Bad expression, and decreased Bcl-2 protein expression. Through stimulation of the activation of c-Jun NH2-terminal protein kinase (JNK) and p38 mitogen-activated protein kinases (MAPK) by PG treatment, we demonstrated that JNK and p38 MPAK are not involved in PG-induced apoptosis using their specific inhibitors. Taken together, these findings indicate that PG induces apoptosis in activated HSCs. The potential anti-fibrotic effect of PG warrants further evaluation.
