Background: Adaptive models of healthcare delivery, such as telehealth consultations, have rapidly been adopted to ensure ongoing delivery of essential healthcare services during the COVID-19 pandemic. However, there remain gaps in our understanding of how clinicians have adapted to telehealth. This study aims to explore the telehealth experiences of specialists, based at a tertiary hospital in the Hunter Region, and general practitioners (GP), including barriers, enablers and opportunities.

Background: In 2006, the research and development (R&D) activity of England's national healthcare system, the National Health Service, was reformed. A National Institute for Health Research (NIHR) was established within the Department of Health, the first body to manage this activity as an integrated system, unlocking significant increases in government funding. This article investigates how the NIHR came to be set up, and why it took the form it did.

Background: Relevant information on health research must be made publicly available in an accurate, timely and accessible manner if evidence is to inform practice and benefit patient care. Failure to publish research information represents a significant waste of research funds. However, recent studies have demonstrated that non-publication and selective or biased reporting remains a significant problem.

Background And Objectives: First-line treatment of chronic phase (CP) chronic myeloid leukemia (CML) is based on the first-generation tyrosine kinase inhibitor (TKI) imatinib or the second-generation TKIs dasatinib or nilotinib. Thanks to the efficacy of TKIs, CML has switched from a fatal to a 'chronic' pathology, and data from clinical trials have become insufficient to drive physicians' prescription choices and address long-term treatment outcomes. On the brink of commercialization of generic imatinib, this study aims to evaluate the therapeutic pattern of CP-CML and the occurrence of adverse events (AEs) over a decade of local real clinical practice.

Comparative effectiveness research (CER) is not new but its potential to improve the effectiveness of healthcare has not yet been exploited in the US. Other countries such as the UK have more experience of this. Key points of the UK experience are summarized here and some possible pointers for the US are drawn.

Background: Breast cancer is the most common cancer affecting women in the UK. Tamoxifen (TAM) is considered as the standard of care for many women with oestrogen receptor positive breast cancer. However, wide variability in the response of individuals to drugs at the same doses may occur, which may be a result of interindividual genetic differences (pharmacogenetics).

A number of strategies have been shown to improve the quality of drug prescriptions. The objective of this study was to implement and assess the effectiveness of 3 interventions on physicians' prescribing and cost containment: training physicians about quality prescribing; regulatory and administrative measures to improve rational drug prescribing; and a multi-faceted approach using 2 these strategies plus additional elements. Three public health centres, 1 for each intervention, were randomly selected; 61 physicians were trained in drug prescribing and completed a pre- and post-training questionnaire; and 100 post-intervention prescriptions from each centre were compared.

Medication errors are globally huge in magnitude and associated with high morbidity and mortality together with high costs and legal problems. Medication errors are caused by multiple factors related to health providers, consumers and health system, but most prescribing errors are preventable. This paper is the third of 3 review articles that form the background for a series of 5 interconnected studies of prescribing patterns and medication errors in the public and private primary health care sectors of Saudi Arabia.

Unlike sub-optimal prescribing, rational prescribing, coupled with certain indicators, is associated with improved safety in drug use in terms of selecting appropriate drug for prescribing, better quality of life for patients and cost-effective care. Medication prescribing is a relatively unexplored area of research in Saudi Arabia and until now most studies have been in the secondary and tertiary health care system. This paper is the second of 3 review articles that form the background for a series of 5 interconnected studies of prescribing patterns and medication errors in the public and private primary health care sectors of Saudi Arabia.

There is wide variability in the response of individuals to standard doses of antipsychotic drugs. It has been suggested that this may be partly explained by differences in the cytochrome P450 (CYP450) enzyme system responsible for metabolizing the drugs. We conducted a systematic review and meta-analyses to consider whether testing for CYP450 single nucleotide polymorphisms in adults starting antipsychotic treatment for schizophrenia predicts and leads to improvements in clinical outcomes.
