ObjectiveTo summarise the findings of an updated Cochrane review of interventions aimed at improving the appropriate use of polypharmacy in older people.DesignCochrane systematic review. Multiple electronic databases were searched including MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials (from inception to November 2013). Hand searching of references was also performed. Randomised controlled trials (RCTs), controlled clinical trials, controlled before-and-after studies and interrupted time series analyses reporting on interventions targeting appropriate polypharmacy in older people in any healthcare setting were included if they used a validated measure of prescribing appropriateness. Evidence quality was assessed using the Cochrane risk of bias tool and GRADE (Grades of Recommendation, Assessment, Development and Evaluation).SettingAll healthcare settings.ParticipantsOlder people (≥65 years) with ≥1 long-term condition who were receiving polypharmacy (≥4 regular medicines).Primary and secondary outcome measuresPrimary outcomes were the change in prevalence of appropriate polypharmacy and hospital admissions. Medication-related problems (eg, adverse drug reactions), medication adherence and quality of life were included as secondary outcomes.Results12 studies were included: 8 RCTs, 2 cluster RCTs and 2 controlled before-and-after studies. 1 study involved computerised decision support and 11 comprised pharmaceutical care approaches across various settings. Appropriateness was measured using validated tools, including the Medication Appropriateness Index, Beers’ criteria and Screening Tool of Older Person's Prescriptions (STOPP)/ Screening Tool to Alert doctors to Right Treatment (START). The interventions demonstrated a reduction in inappropriate prescribing. Evidence of effect on hospital admissions and medication-related problems was conflicting. No differences in health-related quality of life were reported.ConclusionsThe included interventions demonstrated improvements in appropriate polypharmacy based on reductions in inappropriate prescribing. However, it remains unclear if interventions resulted in clinically significant improvements (eg, in terms of hospital admissions). Future intervention studies would benefit from available guidance on intervention development, evaluation and reporting to facilitate replication in clinical practice.

ObjectivesTo explore care home managers’ views and experiences of optimising medicines use for residents with dementia during the COVID-19 pandemic.Design, setting and participantsA descriptive exploratory qualitative study using semistructured interviews (conducted via telephone or online videoconferencing platform), with care home managers across Northern Ireland, purposively sampled from care homes that provided care for residents with dementia. Care home managers were asked to describe their experiences of accessing primary healthcare services (such as those provided by general practitioners and community pharmacists), how medicines use by residents with dementia was affected by the pandemic, and what they had learnt from their experiences. Data were analysed using inductive thematic analysis.ResultsFourteen interviews were conducted between January and July 2022. Four themes, ‘isolation’, ‘burden’, ‘disruption’ and ‘connection and communication’, were identified; isolation was a cross-cutting theme that permeated the other themes. Care home managers described feeling isolated from healthcare professionals, healthcare services and residents’ family members. This isolation placed additional burden on care home staff and residents with dementia by increasing staff workload and negatively affecting residents’ well-being. Participants reported that disruption to primary healthcare service provision, particularly services provided by general practices, had significant impact on residents with dementia. Participants described a lack of face-to-face contact with healthcare professionals, and medication reviews often ceased to take place. The connection and communication between key stakeholders were perceived to be important when optimising medicines for residents with dementia.ConclusionsThis study has highlighted the challenges and initial impact of the COVID-19 pandemic on medicines optimisation for care home residents with dementia, which was characterised by isolation. Further research is needed to determine the extent of the long-term impact of the COVID-19 pandemic on this resident population. In future public health crises, better communication is needed between healthcare professionals and care homes.

Introduction There is concern about the use of anticholinergic medications in people living with dementia (PLWD). Such medicines may increase cognitive decline and may be associated with higher mortality in PLWD who take these medicines. The aim of this study was to analyse data from an online dementia discussion forum to explore the experiences and perspectives of PLWD and carers about the use of anticholinergic medicines in this population. Methods Following receipt of ethical approval, archived discussions (posts) from Dementia Talking Point, a fully public online forum for anyone affected by dementia, created and maintained by the Alzheimer's Society, were searched from the date of inception to January 2022 using a range of search terms including commonly used anticholinergic medicines. Posts, including any of the search terms, were assessed for relevance and analysed using inductive thematic analysis. Results Five hundred and fifty unique posts were analysed, all of which had been provided by carers, with no posts attributed to PLWD. The themes that encompassed carers' experiences were (1) motivators of prescribing, (2) perspectives on the process of prescribing and (3) the outcomes of prescribing. The dominant motivator of prescribing was the management of noncognitive symptoms, pre‐ and postdiagnosis of dementia. Carers' perspectives on the process of prescribing were informed by an assessment of the risk‐benefit of starting a medication and shared decision‐making between the carer and healthcare professional to a greater or lesser degree. The outcomes of prescribing were observing the effects of the medicines, which in turn influenced whether prescribing was reviewed and continued unchanged, continued but amended, reinitiated if the medicine had been previously stopped or discontinued (the process of deprescribing). Conclusion This study has provided unique insights into carers' experiences and perspectives about the use of anticholinergic medications in PLWD, highlighting how commonly these medications are prescribed for PLWD and carers' concerns about their use. There is a clear need for carers and PLWD to receive information about these medicines and healthcare professionals to consider how to optimise the use of these medicines to avoid adverse effects. Patient or Public Contribution This work was informed by findings from previous research studies focusing on optimising medicine use for people with dementia in primary care, in which interviews were conducted with PLWD, their carers and primary healthcare professionals. Although not strictly patient and public involvement, we utilised the feedback provided by key stakeholders to inform the research questions and aim/objectives of this study.

Background People with vision impairment encounter many difficulties when it comes to medicines use. However, evidence indicates that there are major gaps in pharmaceutical care service provision worldwide and limited research on interventions to optimise medication use for this patient population. The Theoretical Domains Framework (TDF) provides a method for theoretically understanding individuals’ behaviour and informing development of interventions. The aim of this research was to (a) identify the barriers and facilitators to the provision of medication dispensing and counselling services by pharmacists to patients with vision impairment, and (b) identify key TDF domains to be targeted in a future intervention. Methods Semi-structured interviews were conducted with pharmacists from different pharmacy practice settings/areas in Saudi Arabia. The 14-domain TDF was utilised as the theoretical lens through which pharmacists’ behaviours were examined. Interviews were conducted in Arabic or English, either face-to-face or over the telephone based on the participant’s preference. Following transcription, interviews conducted in Arabic were translated into English before analysis. Data analysis involved using the framework method and content analysis to identify important barriers and facilitators to the provision of dispensing and counselling services to those with vision impairment. Key TDF domains that could be targeted in a future intervention were then identified using a consensus-based approach. Results Twenty-six pharmacists were interviewed . Pharmacists’ experience in pharmacy practice ranged from two to 28 years. A range of barriers and facilitators were highlighted as important in providing services to those with vision impairment. Eight domains were identified as ‘key domains’ including: ‘Knowledge’, ‘Skills’, ‘Beliefs about capabilities’, ‘Goals’, ‘Memory, attention, and decision processes’, ‘Environmental context and resources’, ‘Social influences’, and ‘Behavioural regulation’. Conclusions Barriers and facilitators identified by pharmacists will inform the development of an intervention to ensure its applicability to everyday practice. Future research will focus on the process of developing the proposed intervention through targeting key TDF domains to improve medication dispensing and counselling by pharmacists to patients with vision impairment.

Urinary tract infections (UTIs) are one of the most common infections in older people and are associated with increased morbidity and mortality. UTIs are also associated with increased risk of antimicrobial resistance (AR). This study examined changes in AR among older inpatients with a primary diagnosis of UTIs in the United States over an 8-year period and the impact of AR on clinical outcomes and hospital costs. Data were obtained from the longitudinal hospital HCUP-NIS database from 2009 to 2016 for inpatient episodes that involved those aged 65+ years. The ICD-9 and ICD-10 codes were used to identify episodes with a primary diagnosis of UTIs, comorbidities, AR status and age-adjusted Deyo-Charlson comorbidity index (ACCI) for the patient concerned. Weighted multivariable regression was used to examine the impact of AR on all-cause inpatient mortality, discharge destination, length of stay and hospital expenditures, adjusted for socio-demographic and clinical covariates. The proportion of admissions with AR increased, from 3.64% in 2009 to 6.88% in 2016 (p<0.001), with distinct patterns for different types of resistance. The likelihood of AR was higher in admissions with high ACCI scores and admissions to hospitals in urban areas. Admissions with AR were more likely to be discharged to healthcare facilities (e.g. care homes) compared to routine discharge (OR 1.81; 95%CI, 1.75-1.86), had increased length of stay (1.12 days; 95%CI, 1.06-1.18) and hospital costs (1259 USD; 95%CI, 1178-1340). Resistance due to MRSA was specifically associated with increased hospital mortality (OR 1.33; 95%CI, 1.15-1.53). Our findings suggest that the prevalence of AR has increased among older inpatients with UTIs in the USA. The study highlights the impact of AR among older inpatients with a primary diagnosis of UTIs on clinical outcomes and hospital costs. These relationships and their implications for the care homes to which patients are frequently discharged warrant further research.

Background Studies have shown that potentially inappropriate prescribing (PIP) is highly prevalent among people with dementia (PwD) and linked to negative outcomes, such as hospitalisation and mortality. However, there are limited data on prescribing appropriateness for PwD in Saudi Arabia. Therefore, we aimed to estimate the prevalence of PIP and investigate associations between PIP and other patient characteristics among PwD in an ambulatory care setting. Methods A cross-sectional, retrospective analysis was conducted at a tertiary hospital in Saudi Arabia. Patients who were ≥ 65 years old, had dementia, and visited ambulatory care clinics between 01/01/2019 and 31/12/2021 were included. Prescribing appropriateness was evaluated by applying the Screening Tool of Older Persons Potentially Inappropriate Prescriptions (STOPP) criteria. Descriptive analyses were used to describe the study population. Prevalence of PIP and the prevalence per each STOPP criterion were calculated as a percentage of all eligible patients. Logistic regression analysis was used to investigate associations between PIP, polypharmacy, age and sex; odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Analyses were conducted using SPSS v27. Results A total of 287 PwD were identified; 56.0% ( n  = 161) were female. The mean number of medications prescribed was 9.0 [standard deviation (SD) ± 4.2]. The prevalence of PIP was 61.0% ( n  = 175). Common instances of PIP were drugs prescribed beyond the recommended duration ( n  = 90, 31.4%), drugs prescribed without an evidence-based clinical indication ( n  = 78, 27.2%), proton pump inhibitors (PPIs) for > 8 weeks ( n  = 75, 26.0%), and acetylcholinesterase inhibitors with concurrent drugs that reduce heart rate ( n  = 60, 21.0%). Polypharmacy was observed in 82.6% ( n  = 237) of patients and was strongly associated with PIP (adjusted OR 24.1, 95% CI 9.0–64.5). Conclusions Findings have revealed a high prevalence of PIP among PwD in Saudi Arabia that is strongly associated with polypharmacy. Future research should aim to explore key stakeholders’ experiences and perspectives of medicines management to optimise medication use for this vulnerable patient population.

Background Although urinary tract infections (UTIs) are extremely common, isolation of causative uropathogens is not always routinely performed, with antibiotics frequently prescribed empirically. This study determined the susceptibility of urinary isolates from two Health and Social Care Trusts (HSCTs) in Northern Ireland to a range of antibiotics commonly used in the treatment of UTIs. Furthermore, we determined if detection of trimethoprim resistance genes ( dfrA ) could be used as a potential biomarker for rapid detection of phenotypic trimethoprim resistance in urinary pathogens and from urine without culture. Methods Susceptibility of E. coli and Klebsiella spp. isolates ( n  = 124) to trimethoprim, amoxicillin, ceftazidime, ciprofloxacin, co-amoxiclav and nitrofurantoin in addition to susceptibility of Proteus mirabilis ( n  = 61) and Staphylococcus saprophyticus ( n  = 17) to trimethoprim was determined by ETEST® and interpreted according to EUCAST breakpoints. PCR was used to detect dfrA genes in bacterial isolates ( n  = 202) and urine samples( n  = 94). Results Resistance to trimethoprim was observed in 37/124 (29.8%) E. coli and Klebsiella spp. isolates with an MIC 90  > 32 mg/L. DfrA genes were detected in 29/37 (78.4%) trimethoprim-resistant isolates. Detection of dfrA was highly sensitive (93.6%) and specific (91.4%) in predicting phenotypic trimethoprim resistance among E. coli and Klebsiella spp. isolates. The dfrA genes analysed were detected using a culture-independent PCR method in 16/94 (17%) urine samples. Phenotypic trimethoprim resistance was apparent in isolates cultured from 15/16 (94%) dfrA -positive urine samples. There was a significant association ( P  < 0.0001) between the presence of dfrA and trimethoprim resistance in urine samples containing Gram-negative bacteria (Sensitivity = 75%; Specificity = 96.9%; PPV = 93.8%; NPV = 86.1%). Conclusions This study demonstrates that molecular detection of dfrA genes is a good indicator of trimethoprim resistance without the need for culture and susceptibility testing.

Introduction Previous studies have highlighted numerous challenges with medicines use for patients with vision impairment, but evidence is lacking on interventions to support safe and effective medicine use for this population. This study aimed to identify potential barriers/facilitators of medicines use from the viewpoint of patients/caregivers, to establish a theory‐informed foundation for a future intervention. Methods Semi‐structured interviews were conducted with patients with vision impairment and their caregivers in Saudi Arabia. Participants were recruited from low‐vision clinics and a non‐profit organisation. The Theoretical Domains Framework (TDF) informed the topic guide and served as the theoretical basis for examining participants' behaviours. Interviews explored the barriers/facilitators to obtaining and taking medicines (i.e. the target behaviours). Data were analysed using the framework method and content analysis. Key TDF domains were identified by assessing the relative frequency of themes, the existence of conflicting themes and the perceived theme impact on target behaviours. Results Twelve patient/caregiver dyads and 18 individual patients were interviewed. Patients' ages ranged from 19 to 88 years, with 21 females and 9 males. Patients/caregivers demonstrated good knowledge of medicines used, and resourcefulness in finding methods to manage medication use (Domains: ‘Knowledge’ and ‘Skills’). ‘Environmental context and resources (ECR)’ and ‘Social influences’ were the two most coded domains. Participants reported the usefulness of several resources including pill organisers and smartphones but described problems with pharmacy environments (Domain: ‘ECR’). Caregivers played a major role in assisting patients with medicines. Participants had some positive encounters with pharmacists but reported difficulties in discussing medication issues with them. Many participants had a narrow view of the pharmacist's role (Domain: ‘Social influences’). Maintaining a routine was a major facilitator under the ‘Memory, attention and decision processes’ and ‘Behavioural regulation’ domains. Six TDF domains were considered ‘key’ to participants' behaviours. Conclusions This study is the first to utilise a theoretical approach to understand the behaviour of patients with vision impairment in relation to medication use. It provides a comprehensive understanding of the role of caregivers and what influences their own behaviours. Findings will inform the future development of an intervention to support safe and effective medicine use for patients with vision impairment. Patient or Public Contribution An author met with an administrator at the ‘National Association of the Blind’ (Kafeef) in Riyadh to enhance the research team's understanding of vision impairment, and the practicality and logistics for identifying and recruiting patients. A draft of the interview guides was piloted with two patients and their caregivers and they were asked for feedback on the questions with amendments made accordingly.

Background People with dementia (PwD) face unique challenges with medicines management, yet little is known about these challenges from the perspectives of primary healthcare professionals, particularly general practitioners (GPs) and community pharmacists. Few medicines management interventions have been developed which are aimed at community-dwelling PwD. This study sought to develop an intervention to improve medicines management for PwD in primary care using a theory-informed approach. Methods Semi-structured interviews were conducted with GPs ( n  = 15) and community pharmacists ( n  = 15) to explore participants’ views and experiences of medicines management for PwD, and their perceptions of barriers and facilitators to successful medicines management for PwD. The 14-domain Theoretical Domains Framework was the underpinning theoretical guide, allowing key theoretical domains to be identified and mapped to behaviour change techniques (BCTs) which are considered the ‘active ingredients’ of an intervention. Draft interventions were developed to operationalise selected BCTs and were presented to GPs and community pharmacists during task groups. Final selection of an intervention for feasibility testing was guided by feedback provided during these task groups and through application of the APEASE (Affordability, Practicability, Effectiveness/cost-effectiveness, Acceptability, Side-effects/safety, Equity) criteria. Results Participants expressed a number of concerns about medicines management for PwD, particularly monitoring adherence to medication regimens and conducting medication review. Two draft interventions comprising selected BCTs (‘Modelling or demonstration of behaviour’; ‘Salience of consequences’; ‘Health consequences’; ‘Social and environmental consequences’; ‘Action planning’; Social support or encouragement’, ‘Self-monitoring of behaviour’) were developed, each targeting GPs and community pharmacists. Following the task groups and discussions within the research team, the community pharmacy-based intervention was selected for future feasibility testing. The intervention will target community pharmacists to conduct a medication review (incorporating an adherence check) with a PwD, delivered as an online video demonstrating key behaviours. The video will include feedback emphasising positive outcomes of performing the behaviours. Action planning and a quick reference guide will be used as complementary intervention components. Conclusions A community pharmacist-based intervention has been developed targeting medicines management for PwD in primary care using a systematic, theory-informed approach. Future work will determine the usability and acceptability of implementing this intervention in clinical practice.

Background Preclinical evidence suggests that statins could delay cancer progression. Previous epidemiological findings have been inconsistent and some have been limited by small sample sizes, as well as certain time-related biases. This study aimed to investigate whether breast cancer patients who were exposed to statins had reduced breast cancer-specific mortality. Methods We conducted a retrospective cohort study of 15,140 newly diagnosed invasive breast cancer patients diagnosed from 2009 to 2012 within the Scottish Cancer Registry. Dispensed medication usage was obtained from linkages to the Scottish Prescribing Information System and breast cancer-specific deaths were identified from National Records of Scotland Death Records. Using time-dependent Cox regression models, hazard ratios (HR) and 95 % confidence intervals (CI) were calculated for the association between post-diagnostic exposure to statins (including simvastatin) and breast cancer-specific mortality. Adjustments were made for a range of potential confounders including age at diagnosis, year of diagnosis, cancer stage, grade, cancer treatments received, comorbidities, socioeconomic status and use of aspirin. Results A total of 1,190 breast cancer-specific deaths occurred up to January 2015. Overall, after adjustment for potential confounders, there was no evidence of an association between statin use and breast cancer-specific death (adjusted HR 0.93, 95 % CI 0.77, 1.12). No significant associations were observed in dose–response analyses or in analysis of all-cause mortality. For simvastatin use specifically, a weak non-significant reduction in breast cancer-specific mortality was observed compared to non-users (adjusted HR 0.89, 95 % CI 0.73, 1.08). Statin use before diagnosis was weakly associated with a reduction in breast cancer-specific mortality (adjusted HR 0.85, 95 % CI 0.74, 0.98). Conclusion Overall, we found little evidence of a protective association between post-diagnostic statin use and cancer-specific mortality in a large nation-wide cohort of breast cancer patients. These findings will help inform the decision whether to conduct randomised controlled trials of statins as an adjuvant treatment in breast cancer.
