Fulltext Awareness, knowledge and views of off-label prescribing in children: a systematic review

Balan S, Hassali MA, Mak VS

Br J Clin Pharmacol, 2015 Dec;80(6):1269-80.
PMID: 26314841 DOI: 10.1111/bcp.12750

AIM: The aim of this review was to provide an updated overview of awareness, knowledge and views of off-label prescribing in children.
METHOD: A literature search using electronic databases including PubMed, Medline, Scopus, Science Direct, Springer Link, Proquest, Ebsco Host and Google Scholar was conducted. Additional articles were identified by reviewing the bibliography of retrieved articles. The articles were searched with any of the following medical subject headings (MeSH) terms in the title: attitude, awareness, knowledge, experience, view, off-label, pediatric, paediatric and children. The inclusion criteria were full text articles published in English between January 2004 and February 2015 and reported outcome related to awareness, knowledge and views regarding off-label prescribing in children. Editorials, reviews, notes, conference proceedings, letters and studies reporting prevalence of off-label prescribing were excluded. The articles were scrutinized using thematic analysis.
RESULTS: Eleven studies conducted among doctors, community pharmacists, paediatric nurses, parents and children met the inclusion criteria. Nine themes were developed through document analysis which included main domains such as knowledge, awareness and views on off-label drug use in children, choice of information sources, reasons and suggestions to reduce off-label prescribing, concern regarding obtaining consent and participation in clinical trials.
CONCLUSION: The studies reviewed reported that the majority of doctors and community pharmacists were familiar with the term off-label prescribing but knowledge among parents was low. Awareness on off-label prescribing in children remains low among all study participants. There is a mismatch between views on off-label prescribing in children of study participants and the finding of previous studies.
Do South Australian pharmacy interns have the educational and behavioural precursors to meet the objectives of Australia's health care reform agenda?

Mak VS, March G, Clark A, Gilbert AL

Int J Pharm Pract, 2014 Oct;22(5):366-72.
PMID: 24428202 DOI: 10.1111/ijpp.12090

OBJECTIVE: To explore South Australian (SA) pharmacy interns' values, beliefs and motivations to study pharmacy and their assessment of how well their pharmacy education has prepared them for activities required of all health professionals under Australia's health care reforms.
METHODS: A postal questionnaire was sent to all 136 SA pharmacy interns enrolled in SA intern training programmes in February 2010 (second month of the intern training programme).
KEY FINDINGS: Sixty (44%) of SA pharmacy interns responded; 75% selected pharmacy as a career because of an interest in health-related sciences and 65% valued working with patients. Respondents believed their pharmacy education prepared them for patient care (80%), providing medicine information (72%) and primary health care delivery (68%), but 51% indicated that they were not prepared for multidisciplinary team care.
CONCLUSIONS: The positive values, beliefs and motivations expressed by respondents are significant behavioural precursors to meet the requirements of health professionals in Australia's health care reforms. Respondents indicated that their pharmacy education provided appropriate training in a number of relevant professional areas.

Fulltext Perspectives of health professionals towards deprescribing practice in Asian nursing homes: a qualitative interview study

Kua CH, Mak VS, Lee SWH

BMJ Open, 2019 10 11;9(10):e030106.
PMID: 31604786 DOI: 10.1136/bmjopen-2019-030106

OBJECTIVE: To examine the determinants of deprescribing among health professionals in nursing homes, focusing on knowledge, practice and attitude.
DESIGN: This was a qualitative study comprising semi-structured face-to-face interviews guided by 10 open-ended questions. Interviews were conducted until data saturation was achieved and no new ideas were formed. The interviews were audio-recorded, transcribed verbatim and analysed for themes. To derive themes, we employed directed content analysis of transcript data. Coding was completed using a combination of open, axial and selective coding.
SETTING: Four nursing homes in Singapore.
PARTICIPANTS: The study involved 17 participants (comprising 4 doctors, 4 pharmacists and 9 nurses).
RESULTS: Two key themes were identified, enablers and challenges. These were enablers and challenges faced by doctors, pharmacists and nurses towards deprescribing. The identified subthemes for enablers of deprescribing were: (1) awareness of medications that are unnecessary or could be targeted for deprescribing; (2) improving quality of life for patients with limited life expectancy; (3) improving communication between doctors, pharmacists and nurses; (4) systematic deprescribing practice and educational tools and (5) acknowledgement of possible benefits of deprescribing. The identified subthemes for challenges of deprescribing were: (1) symptoms not acknowledged as possibly drug-related; (2) lack of knowledge in patient's and family members' preferences; (3) lack of coordination between health professionals in hospitals and nursing homes and (4) limited tools for deprescribing. The development of a local guideline, mentoring nurses, case discussions, better shared decision-making and improving multidisciplinary communication, may help to support the process of deprescribing.
CONCLUSION: In conclusion, this study highlighted that deprescribing in the nursing homes is perceived by health professionals to be challenging and future research could assess how routine case studies, mentoring and better multidisciplinary communication could improve deprescribing knowledge and process in the nursing homes.
Separation of prescribing and dispensing in Malaysia: the history and challenges

Tiong JJ, Mai CW, Gan PW, Johnson J, Mak VS

Int J Pharm Pract, 2016 Aug;24(4):302-5.
PMID: 26777986 DOI: 10.1111/ijpp.12244

This article serves as an update to the work by Shafie et al. (2012) which previously reviewed the benefits of policies separating prescribing and dispensing in various countries to advocate its implementation in Malaysia. This article seeks to strengthen the argument by highlighting not only the weaknesses of the Malaysian health care system from the historical, professional and economic viewpoints but also the shortcomings of both medical and pharmacy professions in the absence of separation of dispensing. It also provides a detailed insight into the ongoing initiatives taken to consolidate the role of pharmacists in the health care system in the advent of separation of dispensing. Under the two tier system in Malaysia at present, the separation of prescribing and dispensing is implemented only in government hospitals. The absence of this separation in the private practices has led to possible profit-oriented medical and pharmacy practices which hinder safe and cost-effective delivery of health services. The call for separation of dispensing has gained traction over the years despite various hurdles ranging from the formidable resistance from the medical fraternity to the public's scepticism towards the new policy. With historical testament and present evidence pointing towards the merits of a system in which doctors prescribe and pharmacists dispense, the implementation of this health care model is justified.
Fulltext Nursing home team-care deprescribing study: a stepped-wedge randomised controlled trial protocol

Kua CH, Yeo CYY, Char CWT, Tan CWY, Tan PC, Mak VS, et al.

BMJ Open, 2017 05 09;7(5):e015293.
PMID: 28490560 DOI: 10.1136/bmjopen-2016-015293

INTRODUCTION: An ageing population has become an urgent concern for Asia in recent times. In nursing homes, polypharmacy has also become a compounding issue. Deprescribing practice is an evidence-based strategy to provide a better outcome in this group of patients; however, its implementation in nursing homes is often challenging, and prospective outcome data on deprescribing practice in the elderly is lacking. Our study assesses the implementation of team-care deprescribing to understand the benefits of this practice in geriatric setting and to explore the factors affecting deprescribing practice.
METHODS AND ANALYSIS: This multicentre prospective study consists of a prestudy interview questionnaire, and a preintervention and postintervention study to be conducted in the nursing home setting on residents at least 65 years old and on five or more medications. We will employ a cluster randomised stepped-wedge interventional design, based on a five-step (reviewing, checking, discussion, communication and documentation) team-care deprescribing practice coupled with the use of a deprescribing guide (consisting of Beers and STOPP criteria, as well as drug interaction checking), to assess the health and pharmacoeconomic outcome in nursing homes' practice. Primary outcome measures of the intervention will consist of fall risks using a fall risk assessment tool. Other outcomes assessed include fall rates, pill burden including number of pills per day, number of doses per day and number of medications prescribed. Cost-related measures will include the use of cost-benefit analysis, which is calculated from the medication cost savings from deprescribing. For the prestudy interview questionnaire, findings will be analysed qualitatively using thematic analysis.
ETHICS AND DISSEMINATION: This study is approved by the Domain Specific Review Board of National Healthcare Group, Singapore (2016/00422) and Monash University Human Research Ethics Committee (2016-1430-7791). The study findings shall be disseminated in international conferences and peer-reviewed publications. The study is registered with ClinicalTrials.gov (NCT02863341), Pre-results.
