Factors associated with statin discontinuation near end of life in a Danish primary health care cohort

BACKGROUND

Long-term preventive treatment such as treatment with statins should be reassessed among patients approaching end of life. The aim of the study was to describe the rate of discontinuation of statin treatment and factors associated with discontinuation in the 6 months before death.

METHODS

This study is a retrospective cohort study using national registers and blood test results from primary health care patients. Patients in the Copenhagen municipality, Denmark who died between 1997 and 2018 and were statin users during the 10-year period before death were included. We calculated the proportion who remained statin users in the 6-month period before death. Factors associated with discontinuation were tested using logistic regression.

RESULTS

A total of 55,591 decedents were included. More patients continued treatment (64%, n = 35,693) than discontinued (36%, n = 19,898) the last 6 months of life. The 70 and 80 age groups had the lowest odds of discontinuing compared to the 90 (OR 1.59, 95% CI 0.93-2.72) and 100 (OR 3.11, 95% CI 2.79-3.47) age groups. Increasing comorbidity score (OR 0.89, 95% CI 0.87; 0.90 per 1-point increase) and use of statins for secondary prevention (OR 0.89, 95% CI 0.85; 0.93) reduced the likelihood of discontinuation as did a diagnosis of dementia, heart failure, or cancer.

CONCLUSION

A substantial portion of patients continued statin treatment near end of life. Efforts to promote rational statin use and discontinuation are required among patients with limited life expectancy, including establishing clear, practical recommendations about statin discontinuation, and initiatives to translate recommendations into clinical practice.

PoLA/CFPiP/PCS/PSLD/PSD/PSH guidelines on diagnosis and therapy of lipid disorders in Poland 2021

In Poland there are still nearly 20 million individuals with hypercholesterolaemia, most of them are unaware of their condition; that is also why only ca. 5% of patients with familial hypercholesterolaemia have been diagnosed; that is why other rare cholesterol metabolism disorders are so rarely diagnosed in Poland. Let us hope that these guidelines, being an effect of work of experts representing 6 main scientific societies, as well as the network of PoLA lipid centers being a part of the EAS lipid centers, certification of lipidologists by PoLA, or the growing number of centers for rare diseases, with a network planned by the Ministry of Health, improvements in coordinated care for patients after myocardial infarction (KOS-Zawał), reimbursement of innovative agents, as well as introduction in Poland of an effective primary prevention program, will make improvement in relation to these unmet needs in diagnostics and treatment of lipid disorders possible.

Outcomes of deprescribing interventions in older patients with life-limiting illness and limited life expectancy: A systematic review

AIMS

Older patients with life-limiting illness (LLI) and limited life expectancy (LLE) continue to receive potentially inappropriate medicines, consequently deprescribing is often necessary. However, deprescribing in this population can be complex and challenging. Therefore, we aimed to investigate the evidence for outcomes of deprescribing interventions in older patients with LLI and LLE.

METHODS

Studies on deprescribing intervention and their outcomes in age ≥65 years with LLI and LLE were searched using PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO and Google Scholar. Medication appropriateness was primary outcome, while clinical and cost-related outcomes were secondary. Eligibility, data extraction and quality assessment were followed by a narrative synthesis of data.

RESULTS

Of 9 studies (1375 participants), 3 reported on primary outcome. One study showed a significant reduction in medication inappropriateness by 34.9% (P < .001) from admission to close-out, the second achieved 29.4% (P < .001) and 15.1% (P = .003) reduction at 12 and 24 months, respectively. The third reported that their intervention stopped (17.2%) and altered the dose (2.6%) of high-risk medications. Commonly reported clinical outcomes were mortality (n = 3), quality of life (n = 2) and falls (n = 2). Outcomes in terms of cost were reported as overall cost (n = 2), medication cost (n = 1) and health care expenditure (n = 1).

CONCLUSION

Our findings suggest that deprescribing in older patients with LLI and LLE can improve medication appropriateness, and has potential for enhancement of several clinical outcomes and cost savings, but the evidence needs to be better established.

Patient Characteristics and General Practitioners' Advice to Stop Statins in Oldest-Old Patients: a Survey Study Across 30 Countries

BACKGROUND

Statins are widely used to prevent cardiovascular disease (CVD). With advancing age, the risks of statins might outweigh the potential benefits. It is unclear which factors influence general practitioners' (GPs) advice to stop statins in oldest-old patients.

OBJECTIVE

To investigate the influence of a history of CVD, statin-related side effects, frailty and short life expectancy, on GPs' advice to stop statins in oldest-old patients.

DESIGN

We invited GPs to participate in this case-based survey. GPs were presented with 8 case vignettes describing patients > 80 years using a statin, and asked whether they would advise stopping statin treatment.

MAIN MEASURES

Cases varied in history of CVD, statin-related side effects and frailty, with and without shortened life expectancy (< 1 year) in the context of metastatic, non-curable cancer. Odds ratios adjusted for GP characteristics (ORadj) were calculated for GPs' advice to stop.

KEY RESULTS

Two thousand two hundred fifty GPs from 30 countries participated (median response rate 36%). Overall, GPs advised stopping statin treatment in 46% (95%CI 45-47) of the case vignettes; with shortened life expectancy, this proportion increased to 90% (95CI% 89-90). Advice to stop was more frequent in case vignettes without CVD compared to those with CVD (ORadj 13.8, 95%CI 12.6-15.1), with side effects compared to without ORadj 1.62 (95%CI 1.5-1.7) and with frailty (ORadj 4.1, 95%CI 3.8-4.4) compared to without. Shortened life expectancy increased advice to stop (ORadj 50.7, 95%CI 45.5-56.4) and was the strongest predictor for GP advice to stop, ranging across countries from 30% (95%CI 19-42) to 98% (95% CI 96-99).

CONCLUSIONS

The absence of CVD, the presence of statin-related side effects, and frailty were all independently associated with GPs' advice to stop statins in patients aged > 80 years. Overall, and within all countries, cancer-related short life expectancy was the strongest independent predictor of GPs' advice to stop statins.

Prevalence and Incidence of Statin Use and 3-Year Adherence and Discontinuation Rates Among Older Adults With Dementia

OBJECTIVE

To examine the patterns of statin use and determine the 3-year adherence and discontinuation rates among a cohort of Australians aged ≥65 years with dementia.

METHODS

The yearly prevalence and incidence of statin use were compared via Poisson regression modeling using 2007 as the reference year. People with dementia were identified according to dispensing of antidementia medications. A cohort of 589 new statin users was followed longitudinally. Adherence was estimated via the proportion of days covered (PDC). Discontinuation was defined as ≥90 days without statin coverage.

RESULTS

The annual prevalence of statin use among older Australians with dementia increased from 20.6% in 2007 to 31.7% in 2016 (aged-sex adjusted rate ratio: 1.51, 95% confidence interval: 1.35-1.69). Among the new users, the proportion adherent (PDC ≥ 0.80) decreased from 60.3% at 6 months to 31.0% at 3 years. During the 3-year follow-up, 58.7% discontinued their statin.

CONCLUSIONS

Despite increased use of statins among older Australians with dementia, adherence is low and discontinuation is high, which may point to intentional cessation.

Deprescribing: the emerging evidence for and the practice of the 'geriatrician's salute'

The process of a health professional withdrawing medicines for which the current risk may outweigh the benefit in the individual patient has been given a variety of names including the colloquial 'geriatrician's salute', 'de-intensification' and increasingly 'deprescribing'. The rise of deprescribing as a word with a definition, evidence base and implementation plan, reflects the changing environment in which we practice. In particular, the emphasis on evidence-based medicine and the need to care for our expanding ageing populations, which requires application of components of geriatric evaluation and management by a wider range of health care practitioners. However, there are still significant challenges related to research on the safety, efficacy and implementation of deprescribing. In this commentary, we discuss the current evidence on the effects of deprescribing, emergence of implementation tools to embed deprescribing into the clinical care of older adults, as well as efforts to develop guidelines to improve health care practitioners' awareness and self-efficacy of deprescribing. Ultimately, judicious prescribing and deprescribing, across a wide range of health care settings, ought to enable older people to use medicines to support their achievable ageing goals.

Evaluation of the National Minimum Data Set for Neurological Conditions in Older Adults

AIM

To evaluate the National Minimum Data Set (NMDS) against the International Resident Assessment Instrument-Home Care (interRAI-HC) in diagnosing dementia or Parkinson disease (PD).

METHOD

The NMDS data were matched with interRAI-HC for all older individuals in New Zealand. Dementia or PD was compared within 90 and 180 days and 1 to 4 years preceding and subsequent to the date of diagnosis in interRAI-HC. Consistency was measured through sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), weighted kappa (κ), and McNemar test.

RESULTS

For a diagnosis within 90 days, dementia showed 60.77% sensitivity, 95.33% specificity, 68.46% PPV, and 93.58% NPV. The PD showed 65.74% sensitivity, 99.52% specificity, 80.43% PPV, and 98.98% NPV. κ for dementia (κ = 0.59), PD (κ = 0.720), and McNemar test was significant ( P < .001) for all lengths of follow-up.

CONCLUSION

Substantial agreement between multiple sources of health data can be a valuable resource for decision-making in older people with neurological conditions.
