Mortality in people who use illicit opioids in England

People who use illicit opioids have a high risk of premature mortality, with a mortality rate ten times that of the general population. However, causes of mortality in this group have changed over time in the UK, alongside an ageing and increasingly comorbid population of drug users. The trend in increasing age among people who use illicit opioid has been suggested to be driving the recent increases in drug-related mortality observed in national surveillance data in England.</p

Lessons learned from COVID-19: improving breast cancer care post-pandemic from the patient perspective

Background: Since the onset of the pandemic, breast cancer (BC) services have been disrupted in most countries. The purpose of this qualitative study is to explore the unmet needs, patient-priorities, and recommendations for improving BC healthcare post-pandemic for women with BC and to understand how they may vary based on social determinants of health (SDH), in particular socio-economic status (SES). Methods: Thirty-seven women, who were purposively sampled based on SDH and previously interviewed about the impact of COVID-19 on BC, were invited to take part in follow-up semi-structured qualitative interviews in early 2023. The interviews explored their perspectives of BC care since the easing of COVID-19 government restrictions, including unmet needs, patient-priorities, and recommendations specific to BC care. Thematic analysis was conducted to synthesize each topic narratively with corresponding sub-themes. Additionally, variation by SDH was analyzed within each sub-theme. Results: Twenty-eight women (mean age = 61.7 years, standard deviation (SD) = 12.3) participated in interviews (response rate = 76%). Thirty-nine percent (n = 11) of women were categorized as high-SES, while 61% (n = 17) of women were categorized as low-SES. Women expressed unmet needs in their BC care including routine care and mental and physical well-being care, as well as a lack of financial support to access BC care. Patient priorities included the following: developing cohesion between different aspects of BC care; communication with and between healthcare professionals; and patient empowerment within BC care. Recommendations moving forward post-pandemic included improving the transition from active to post-treatment, enhancing support resources, and implementing telemedicine where appropriate. Overall, women of low-SES experienced more severe unmet needs, which in turn resulted in varied patient priorities and recommendations. Conclusion: As health systems are recovering from the COVID-19 pandemic, the emphasis should be on restoring access to BC care and improving the quality of BC care, with a particular consideration given to those women from low-SES, to reduce health inequalities post-pandemic.</p

Prioritising the content and delivery of a work-focused intervention for women with breast cancer using the nominal group technique

Background: Increased breast cancer survivorship has prompted a focus on optimising quality of life for this cohort, including reintegration into employment. Despite this, there remains a lack of work-focused interventions to support work outcomes for women living with and beyond breast cancer. Objective: The aim of this study was to prioritise the content and delivery of a work-focused intervention for women living with and beyond breast cancer. Methods: Twelve stakeholders including women living with and beyond breast cancer, healthcare professionals, cancer support centre staff, and policy informers were invited to participate in an online discussion using the Nominal Group Technique (NGT) to determine priorities for a work-focused intervention. The NGT seeks consensus through four steps; (i) idea generation, (ii) discussion among the group, (iii) refining ideas, and (iv) ranking preference for ideas through anonymised voting. Results: Intervention content prioritised included managing cancer-related symptoms and work-specific factors. Consensus was made for a blended delivery format (mix of group and individual sessions), and blended delivery (face-to-face and online). Findings indicated a preference for a six-week intervention, with 90-120 minute sessions. Community-based settings were preferred over hospital-based services for the setting of a work-focused intervention. Zoom Video Communications Inc. was the preferred setting to deliver an online intervention. Conclusion: Stakeholder priorities informed the content and delivery of a work-focused intervention for women with breast cancer. A pilot of the proposed intervention will be conducted to test for feasibility and acceptability.</p

Rehabilitation interventions to support return to work for women with breast cancer: a systematic review and meta-analysis

Background: Research recommends the development and evaluation of interventions to support women with breast cancer in returning to, or managing, work. Despite this, there has historically been a paucity of rehabilitation interventions to support women with breast cancer to maintain or return to their work role. The aim of this systematic review was to examine key characteristics of rehabilitation interventions, and their effectiveness on work outcomes for women with breast cancer, compared to usual care. Methods: A systematic review was conducted of controlled studies of rehabilitation interventions with work outcomes for women with breast cancer. Six databases were systematically searched: EMBASE, Web of Science, MEDLINE (OVID), CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials (CENTRAL). Results are presented either as pooled odds ratio (OR) or pooled effect size (hedges g) between groups, with 95% confidence intervals (CI). Narrative synthesis was conducted on intervention outcomes not suitable for meta-analysis. Results: Five thousand, five hundred and thirty-five studies were identified. Nine out of 28 abstracts met inclusion criteria. Heterogeneity of interventions and outcomes precluded meta-analysis for most outcomes. Of the interventions included in meta-analysis, no significant differences compared to usual care were found for sick leave (2 studies (12 months); OR 1.11 (95% CI: 0.66 to 1.87), number of sick days taken (2 studies (six months); difference in effect: - 0.08, (95% CI: - 0.48 to 0.38) or working hours (2 studies (12 months); 0.19, (95% CI: - 0.20 to 0.64). Only one study, with a multidisciplinary intervention, showed a significant difference for work outcomes when compared to usual care. Work-specific content featured in three interventions only, none of which provided conclusive evidence for improvement in work outcomes. Enhanced physical and psychological sequalae, and quality of life was observed in some studies. Conclusion: There remains a lack of effective and methodologically rigorous rehabilitation intervention studies for breast cancer survivors. The development and evaluation of effective rehabilitation interventions to support return to work is warranted.</p

Costs associated with adverse drug reactions in an older population admitted to hospital: a prospective cohort study

Purpose: This study examines healthcare costs associated with adverse drug reactions (ADR) in an older population admitted acutely to an Irish tertiary hospital Methods: Prospective cohort study involving older persons admitted to hospital with and without an ADR. Data was collected at baseline, during hospitalisation and post-discharge. Participants provided information on healthcare resource use three months before admission (baseline) and three months after discharge (follow-up). For each healthcare resource, unit costs were derived and applied. The average cost (standard deviation (SD)) associated with the hospital admission for the ADR and non-ADR are presented. In addition, baseline and follow-up care costs were compared using difference-in-difference analysis and presented with 95% confidence intervals (CI). Costs by preventability and severity of ADR are also presented. Results: A total of n = 230 participants were included (n = 93 ADR and n = 137 without ADR). The average cost associated with hospital admission for an ADR was €9538 (SD €10442) and €9828 (SD €11770) for non-ADR. The additional follow-up costs (difference-in-difference) associated with the ADR was estimated at €2047 (95% CI: -€889 to €4983). The mean incremental follow-up cost of definite preventable ADRs was estimated at €1648 (95% CI: -€4310 to €7605), possible preventable ADRs €2259 (95 CI: -€1194 to €5712) and unavoidable ADRs €1757 (95% CI: -€3377 to €6890). The mean incremental follow-up cost associated with moderate severe ADRs was estimated at €1922 (95% CI: -€1088 to €4932) and €3580 (95% CI: -€4898 to €12,058) for severe ADRs. CONCLUSION: ADRs leading to hospital admission are associated with modest incremental healthcare costs during and three months after admission. Severe and possibly preventable ADRs were associated with higher costs. Conclusion: ADRs leading to hospital admission are associated with modest incremental healthcare costs during and three months after admission. Severe and possibly preventable ADRs were associated with higher costs.</div

Fixed-dose combination antihypertensives and risk of medication errors

Objective: While fixed-dose combinations (FDC) can improve adherence, they may add complexity to the prescribing/dispensing process, potentially increasing risk of medication errors. This study aimed to determine if prescriptions for antihypertensive FDCs increase the risk of therapeutic duplication and drug-drug interactions (DDI).Methods: This retrospective observational study used administrative pharmacy claims data from the Irish Primary Care Reimbursement Service. Prescriptions dispensed to adults in 2015 were included if they contained an antihypertensive FDC, or the same drugs prescribed separately. The outcomes were therapeutic duplication and potentially serious DDI involving FDC drugs. Relative risk (RR) of these outcomes, adjusted for prescription and patient factors, was determined using generalised linear models with Poisson distributions and propensity score matching.Results: This study included 307 833 FDC prescriptions (67.0%) and 151 632 separate component prescriptions. Half of patients prescribed FDCs were female with a mean age of 67.1 (SD 12.5) years and, compared with separate component prescriptions, FDCs were less often coprescribed with other cardiovascular medications. Therapeutic duplication occurred in 0.8% of prescriptions, most often involving calcium channel blockers, and 10.6% contained a DDI (most often amlodipine and simvastatin). The RR of therapeutic duplication on FDC prescriptions compared with separate component prescriptions was 1.46 (95% CI 1.17 to 1.83) and the adjusted RR was 2.06 (95% CI 1.64 to 2.60). For DDIs, there was no significant difference between FDC and separate component prescriptions after confounder adjustment.Conclusions: This study found FDCs were associated with increased risk of duplication. When considering prescribing FDCs, this safety consideration should be weighed against potential benefits.</p

Trends in attention-deficit and hyperactivity disorder (ADHD) medications among children and young adults in Ireland: a repeated cross-sectional study from 2005 to 2015

Objective: This study examined the prescribing patterns of attention-deficit hyperactivity disorder (ADHD) medications in Ireland between 2005 and 2015 in children, adolescents and young adults, and concomitant use of psychotropic medication. Design: Repeated cross-sectional study. Setting: Community setting using pharmacy claims data in Ireland. Participants: Children and young adults aged 0-24 years. Primary and secondary outcomes: Authorised medications used to treat ADHD during the study period, methylphenidate, dexamfetamine, lisdexamfetamine dimesylate and atomoxetine were extracted from a national pharmacy claims database. Dispensing of concomitant psychotropic medications including antipsychotics, anxiolytics, hypnotics/sedatives and antidepressants were examined. Results: The number on any ADHD medication ranged from 1913 in 2005 to 4853 in 2015, and the prevalence rate per 1000 eligible population aged Conclusions: There were significantly higher rates of ADHD prescribing in children/adolescents and a significant increase in the coprescribing of antidepressants. The reasons for the increase are unclear but may reflect increasing awareness and diagnosis of the condition.</p

Drug-drug interactions and their association with adverse health outcomes in the older community-dwelling population: a prospective cohort study

Background: Evidence on associations between drug-drug interactions (DDIs) and health outcomes in the older community-dwelling population is limited. Objective: We estimate potentially clinically important DDI prevalence and examine the association between DDIs and (1) adverse drug events (ADEs), (2) emergency hospital attendance and (3) health-related quality of life (HRQoL) in an older community-dwelling population in Ireland. Methods: This is a prospective cohort study of community-dwelling older adults (N = 904) aged ≥ 70 years from 15 general practices in Ireland recruited in 2010 (wave-1) and followed-up over 2 years (wave-2; 2012-2013), with linked national pharmacy claims data. Individuals dispensed two or more drugs (wave-1: N = 842; wave-2: N = 763) were included. DDI prevalence at baseline, follow-up and 6 months prior to each health outcome was estimated. Multi-level regression was used to model the association between DDI-exposure and health outcomes at follow-up. DDI prevalence, adjusted incidence-rate ratios (aIRR), adjusted odds ratios (aOR), β coefficients and robust standard error (RSE) from multi-level regression analyses, and 95% confidence intervals (CIs) are reported. Results: At wave-1, n = 196 (23.3% [95% CI 20.5-26.3]), individuals were potentially exposed to ≥ 1 DDI, increasing to n = 345 (45.2% [41.7-48.9]) at wave-2. At 2-year follow-up, the median number of ADEs was 3 (interquartile range [IQR 2-5]); 229 (30.1%) had ≥ 1 emergency hospital attendance, and the mean EQ-5D was 0.74 (± 0.23). Evidence for the association between DDI-exposure and emergency hospital attendance at follow-up was lacking (aOR = 1.38 [0.42-4.53]). DDI-exposure was associated with an increasing number of ADEs (aIRR = 1.26 [1.03-1.55]), and decreasing EQ-5D utility (β = - 0.07, [-0.11 to -0.04], RSE = 0.02). Aspirin-warfarin, clarithromycin-prednisolone, amiodarone-furosemide, clarithromycin-salbutamol, rosuvastatin-warfarin, amiodarone-bisoprolol, and aspirin-nicorandil were common DDIs 6 months preceding these health outcomes. Conclusions: We found a two-fold increase in DDI prevalence between wave 1 and 2. DDI exposure was associated with increasing ADEs and declining HRQoL at 2-year follow-up. Common DDIs involved anticoagulants, cardiovascular and antimicrobial drugs, which should be targeted for medicine optimisation.</p

Cognitive impairment and cardiovascular medication use: Results from wave 1 of The Irish Longitudinal Study on Ageing.

AIM: To explore the association between cardiovascular medication use and cognitive impairment in adults aged 50 years and over. METHOD: This cross-sectional linked database study involved secondary quantitative analysis of 1903 participants from wave 1 of the Irish Longitudinal Study on Ageing with available pharmacy claims data. Cognitive impairment was assessed using a cut-off of ≤23 on the Montreal Cognitive Assessment. Cardiovascular medication use was calculated using the proportion of days covered for antihypertensive, antithrombotic, and lipid-modifying medications. For each class of cardiovascular medication, participants were categorized as belonging to one of three medication use groups: (1) not dispensed any medications (reference); (2) poor adherence (proportion of days covered RESULTS: Controlling for demographic and health variables, there was no evidence of an independent association between impaired cognitive function and use of antihypertensives [good adherence OR (95% CI): 1.16 (0.88, 1.52), poor adherence OR (95% CI): 1.39 (0.95, 2.04)]; antithrombotics [good adherence OR (95% CI): 1.26 (0.93, 1.70), poor adherence OR 95% CI): 1.13 (0.80, 1.59)]; or lipid-modifying agents [good adherence OR (95% CI): 0.95 (0.71, 1.25), poor adherence OR (95% CI): 0.88 (0.64, 1.22)]. CONCLUSION: We found no evidence of an association between cardiovascular medication use and cognitive function. Future studies should investigate the prospective associations between cognition and use of cardiovascular medications using longitudinal data.</p

Economic impact of potentially inappropriate prescribing and related adverse events in older people: a cost-utility analysis using Markov models.

OBJECTIVES: To determine the economic impact of three drugs commonly involved in potentially inappropriate prescribing (PIP) in adults aged ≥65 years, including their adverse effects (AEs): long-term use of non-steroidal anti-inflammatory drugs (NSAIDs), benzodiazepines and proton pump inhibitors (PPIs) at maximal dose; to assess cost-effectiveness of potential interventions to reduce PIP of each drug. DESIGN: Cost-utility analysis. We developed Markov models incorporating the AEs of each PIP, populated with published estimates of probabilities, health system costs (in 2014 euro) and utilities. PARTICIPANTS: A hypothetical cohort of 65 year olds analysed over 35 1-year cycles with discounting at 5% per year. OUTCOME MEASURES: Incremental cost, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios with 95% credible intervals (CIs, generated in probabilistic sensitivity analysis) between each PIP and an appropriate alternative strategy. Models were then used to evaluate the cost-effectiveness of potential interventions to reduce PIP for each of the three drug classes. RESULTS: All three PIP drugs and their AEs are associated with greater cost and fewer QALYs compared with alternatives. The largest reduction in QALYs and incremental cost was for benzodiazepines compared with no sedative medication (€3470, 95% CI €2434 to €5001; -0.07 QALYs, 95% CI -0.089 to -0.047), followed by NSAIDs relative to paracetamol (€806, 95% CI €415 and €1346; -0.07 QALYs, 95% CI -0.131 to -0.026), and maximal dose PPIs compared with maintenance dose PPIs (€989, 95% CI -€69 and €2127; -0.01 QALYs, 95% CI -0.029 to 0.003). For interventions to reduce PIP, at a willingness-to-pay of €45 000 per QALY, targeting NSAIDs would be cost-effective up to the highest intervention cost per person of €1971. For benzodiazepine and PPI interventions, the equivalent cost was €1480 and €831, respectively. CONCLUSIONS: Long-term benzodiazepine and NSAID prescribing are associated with significantly increased costs and reduced QALYs. Targeting inappropriate NSAID prescribing appears to be the most cost-effective PIP intervention.</p
