Beliefs, practices, perceptions and motivations of healthcare professionals on medication deprescribing during end-of-life care: A systematic review.

AIM: Conduct a systematic review to investigate current beliefs, practices, perceptions, and motivations towards deprescribing practices from the healthcare professional perspective in older adults residing in long term care facilities with cardiometabolic conditions, using a narrative approach. METHODS: Studies were identified using a literature search of MEDLINE, CINAHL and Web of Science from inception to June 2023 Two reviewers (EH and AA) independently extracted data from each selected study using a standardised self-developed data extraction proforma. Studies reviewed included cross-sectional and observational studies. Data was extracted on baseline characteristics, motivations and beliefs and was discussed using a narrative approach. RESULTS: Eight studies were identified for inclusion. Deprescribing approaches included complete withdrawal, dose reduction, or switching to an alternative medication, for at least one preventive medication. Most healthcare professionals were willing to initiate deprescribing strategies and stated the importance of such interventions, however many felt inexperienced and lacked the required knowledge to feel comfortable doing so. CONCLUSION: Deprescribing is a key strategy when managing older people with cardiometabolic and multiple long term conditions (MLTC). Overall, HCPs including specialists, were happy to explore deprescribing strategies if provided with the relevant training and development to do so. Barriers that still exist include communication and consultation skills, a lack of evidence-based guidance and trust based policies, and a lack of MDT communications and involvement.

Deprescribing in cardiometabolic conditions in older patients: a systematic review.

We conduct a systematic review to investigate current deprescribing practices and evaluate outcomes and adverse events with deprescribing of preventive medications in older patients with either an end-of-life designation or residing in long-term care facilities with cardiometabolic conditions. Studies were identified using a literature search of MEDLINE, EMBASE, Web of Science, clinicaltrials.gov.uk, CINAHLS, and the Cochrane Register from inception to March 2022. Studies reviewed included observational studies and randomised control trials (RCTs). Data was extracted on baseline characteristics, deprescribing rates, adverse events and outcomes, and quality of life indicators, and was discussed using a narrative approach. Thirteen studies were identified for inclusion. Deprescribing approaches included complete withdrawal, dose reduction or tapering, or switching to an alternative medication, for at least one preventive medication. Deprescribing success rates ranged from 27 to 94.7%. The studies reported no significant changes in laboratory values or adverse outcomes but did find mixed outcomes for hospitalisations and a slight increase in mortality rates when comparing the intervention and control groups. Lack of good-quality randomised control trials suggests that deprescribing in the older population residing in long-term care facilities with cardiometabolic conditions and multimorbidity is feasible when controlled and regularly monitored by an appropriate healthcare clinician, and that the benefits outweigh the potential harm in this cohort of patients. Due to the limited evidence and the heterogeneity of studies, a meta-analysis was not performed and as such further research is required to assess the benefits of deprescribing in this patient population.

Word recognition in competing babble and the effects of age, temporal processing, and absolute sensitivity.

This study was designed to clarify whether speech understanding in a fluctuating background is related to temporal processing as measured by the detection of gaps in noise bursts. Fifty adults with normal hearing or mild high-frequency hearing loss served as subjects. Gap detection thresholds were obtained using a three-interval, forced-choice paradigm. A 150-ms noise burst was used as the gap carrier with the gap placed close to carrier onset. A high-frequency masker without a temporal gap was gated on and off with the noise bursts. A continuous white-noise floor was present in the background. Word scores for the subjects were obtained at a presentation level of 55 dB HL in competing babble levels of 50, 55, and 60 dB HL. A repeated measures analysis of covariance of the word scores examined the effects of age, absolute sensitivity, and temporal sensitivity. The results of the analysis indicated that word scores in competing babble decreased significantly with increases in babble level, age, and gap detection thresholds. The effects of absolute sensitivity on word scores in competing babble were not significant. These results suggest that age and temporal processing influence speech understanding in fluctuating backgrounds in adults with normal hearing or mild high-frequency hearing loss.
