Attitudes towards deprescribing and the influence of health literacy among older Australians

Attitudes and barriers towards deprescribing in older patients experiencing polypharmacy: a narrative review

Polypharmacy, commonly defined as ≥5 medications, is a rising public health concern due to its many risks of harm. One commonly recommended strategy to address polypharmacy is medication reviews, with subsequent deprescription of inappropriate medications. In this review, we explore the intersection of older age, polypharmacy, and deprescribing in a contemporary context by appraising the published literature (2012-2022) to identify articles that included new primary data on deprescribing medications in patients aged ≥65 years currently taking ≥5 medications. We found 31 articles were found which describe the current perceptions of clinicians towards deprescribing, the identified barriers, key enabling factors, and future directions in approaching deprescribing. Currently, clinicians believe that deprescribing is a complex process, and despite the majority of clinicians reporting feeling comfortable in deprescribing, fewer engage with this process regularly. Common barriers cited include a lack of knowledge and training around the deprescribing process, a lack of time, a breakdown in communication, perceived 'abandonment of care', fear of adverse consequences, and resistance from patients and/or their carers. Common enabling factors of deprescribing include recognition of key opportunities to instigate this process, regular medication reviews, improving lines of communication, education of both patients and clinicians and a multidisciplinary approach towards patient care. Addressing polypharmacy requires a nuanced approach in a generally complex group of patients. Key strategies to reducing the risks of polypharmacy include education of patients and clinicians, in addition to improving communication between healthcare providers in a multidisciplinary approach.

Factors associated with poor health literacy in older adults: A systematic review

OBJECTIVES

To identify factors associated with poor health literacy in older adults.

METHODS

A systematic literature review was conducted, employing the descriptors "Aged" and "Health Literacy".

PROSPERO - CRD

42022350140.

RESULTS

Out of 23,500 articles screened, 176 were selected. Several factors associated with poor health literacy in older adults were identified, such as sociodemographic (e.g., advanced age, low educational level, non-white population, and others), social (e.g., poor family/social support, loneliness, social isolation, few social activities, and others), economic (e.g., lower income and/or lower socioeconomic status) and health aspects (e.g., poor health, chronic conditions, mental health challenges, hospitalizations, frailty, physical inactivity, cognitive impairment, and others).

CONCLUSIONS

The factors associated with poor health literacy in older adults identified in this review could contribute to future research, support interventions to improve health literacy, and assist professionals in planning educational activities and public policies.

Older Adult Attitudes toward Deprescribing Statins in Primary Cardiovascular Prevention Versus General Medications

Background: There is little evidence for statins for primary cardiovascular prevention in older adults. Consequently, it is important to assess patient attitudes toward the use of statins, which might differ from attitudes toward other medications. We aimed to describe older patient attitudes toward deprescribing statins versus general medications. Methods: We conducted a survey using the revised Patients' Attitudes Toward Deprescribing questionnaire in its original version and adapted to statin use in adults ≥65 years taking a statin for primary prevention. Results: Among the 47 participants (mean age 74.6 years), 42 (89%) were satisfied with their current therapy, but still willing to stop ≥1 of their medications upon their doctor's advice. About 68% (N = 32) were satisfied with their statin therapy, while 83% (N = 39) would accept to consider deprescribing. Twenty-six (55%) participants were concerned about missing future benefits when stopping their general medications and 17 (36%) when stopping their statin. Eight (17%) participants believed they were experiencing side effects of statins and twice as many for general medication (38%, N = 18). Conclusion: Our study provides insight about differences and similarities in patient attitudes toward deprescribing general medications and statins in primary prevention. This information could support patient-centered conversations and shared-decision making about deprescribing.

Predictors of older patients' willingness to have medications deprescribed: A cross-sectional study

BACKGROUND

Deprescribing is a complex process requiring a patient-centred approach. One frequently expressed deprescribing barrier is patients' attitudes and beliefs towards deprescribing. This study aimed to identify the predictors of patients' willingness to have medications deprescribed.

METHODS

A cross-sectional study was conducted with community-dwelling patients aged ≥65 who are taking at least one regular medication. Data collection included patients' demographic and clinical characteristics and the Portuguese revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire. Descriptive statistics were used to present the patients' characteristics. Multiple binary logistic regression analysis was performed to identify the predictors of the patients' willingness to have medications deprescribed.

RESULTS

One hundred ninety-two participants (median age 72 years; 65.6% female) were included. Most (83.33%) were willing to have medications deprescribed, and the predictors were age (adjusted odds ratio [aOR] = 1.136; 95% CI 1.026, 1.258), female sex (aOR = 3.036; 95% CI 1.059, 8.708) and the rPATD concerns about stopping factor (aOR = 0.391; 95% CI 0.203, 0.754).

CONCLUSIONS

Most patients were willing to have their medications deprescribed if it is recommended by their doctors. Older age and female sex increased the odds of willingness to deprescribe; higher concerns about stopping medications decreased the odds. These findings suggest that addressing patients' concerns about stopping their medicines may contribute to deprescribing success.

Deprescribing in Real Time: Hospitalized Septuagenarian With Polypharmacy

Polypharmacy is a common and potentially preventable contributor to recurring emergency room visits, hospitalization, morbidity, and mortality. Its consequences are magnified in older adults due to the age-related decrease in functional and physiologic reserves, increased blood-brain barrier permeability, and altered drug metabolism, among others. In this article, we describe a case of polypharmacy in a septuagenarian to highlight the deprescribing approach implemented by the inpatient care team and to offer patient-centered insights to clinicians (primary care providers and hospitalists) when making deprescribing decisions. The overarching aim of this article is to build on existing literature regarding polypharmacy, prescribing cascades, and deprescribing in the context of what matters most and aligns with patient health priorities. This article highlights the importance of good geriatric medication reconciliation stewardship to avoid harm.

Exploring Older Adult Health Literacy in the Day-to-Day Management of Polypharmacy and Making Decisions About Deprescribing: A Mixed Methods Study

BACKGROUND

Polypharmacy use in older adults is increasing and sometimes leads to poor health outcomes. The influence of health literacy in managing polypharmacy and making decisions about stopping medication has received limited attention.

OBJECTIVE

A mixed methods design was used to measure and investigate the influence of health literacy in the management of polypharmacy and decisions about deprescribing. Phase 1 involved two cross-sectional surveys, one with older adults using five or more medications and the other with general practitioners (GPs).

METHODS

Older adult health literacy was measured using the All Aspects of Health Literacy Scale. Phase 2 employed individual interviews with both older adults and GPs and further explored the reported use of health literacy in practice. SPSS version 24 was used to conduct descriptive statistical analysis of the Phase 1 survey responses and Phase 2 interviews were analyzed using thematic analysis with the assistance of NVivo 12.

KEY RESULTS

Phase 1 survey responses were received from 85 GPs and 137 older adults. Phase 2 interviews were conducted with 16 GPs and 25 older adults. Phase 1 results indicated that self-reported older adult health literacy was high, and that GPs believed older patients could engage in decisions about deprescribing. Phase 2 findings showed that older adults developed and employed complex health literacy practices to manage medications between consultations; however, few reported using their health literacy skills in consultations with their GPs. GPs noted that older adult involvement in decision-making varied and generally thought that older adults had low health literacy.

CONCLUSION

Older adults reported using health literacy practices in the management of their sometimes-complex medication regimens. However, the role of health literacy in deprescribing decision-making was limited. The mixed methods approach allowed greater insight into older adult and GP practices that influence the acquisition and use of health literacy. [HLRP: Health Literacy Research and Practice. 2023;7(1):e14-e25.] Plain Language Summary: This report explores health literacy in the use of multiple medications and decisions to stop using medication/s in older age. Older adults reported good heath literacy and practiced many health literacy skills in the management of their medications. However, they did not always report the use of their health literacy skills when discussing their medications with their family doctor.

Factors which influence the deprescribing decisions of community-living older adults and GPs in Australia

Deprescribing aims to reduce polypharmacy and inappropriate medication use. Both General Practitioners (GPs) and older adults have expressed a willingness to consider deprescribing. However, deprescribing is often deferred in practice. The aim of this study was to identify factors which influence GP and older adult decisions about deprescribing in primary care. Semi-structured interviews were used in this qualitative study, conducted in a regional area in Australia. Participants included GPs and adults aged 65 years or older, using five or more medications and living independently in the community. Data were collected between January 2018 and May 2019. Thematic analysis was used to analyse the verbatim transcribed interviews using NVivo 12. A total of 41 interviews were conducted, 25 with older adults and 16 with GPs. Four key themes influenced deprescribing decisions: views of ageing, shared decision-making, attitudes toward medication use and characteristics of the health care environment. Discussions of deprescribing were limited by the influence of negative stereotypes toward age and ageing, a lack of older adult participation in shared decision-making, a positive attitude towards ongoing medication use and perception of the normality of using medications in older age. Time constraints, poor communication about prescribing information and unclear roles regarding responsibility for deprescribing also prevented discussions. Continuity of care, involvement of older adults in medication reviews and GPs who asserted their generalist role were the main factors which promoted discussion of deprescribing. GPs are well placed to discuss deprescribing with their older patients because they are trusted and can provide continuity of care. Actively encouraging and involving older adults in medication reviews in order to understand their preferences, supports shared decision-making about deprescribing. Active involvement may also reduce the influence of negative views of ageing held by both older adults and GPs.

A Study on the Perceptions of Korean Older Adult Patients and Caregivers about Polypharmacy and Deprescribing

Polypharmacy is continuously increasing among older adults. The resultant potentially inappropriate medications (PIMs) can be harmful to patient health. Deprescribing refers to stopping or reducing PIMs. In this study, the current status of polypharmacy and willingness of older adults to deprescribe were investigated among patients and caregivers who are not associated with one another. The survey used the Korean translated version of the revised Patients' Attitude Towards Deprescribing (rPATD) Scale. Data were collected through an online survey of 500 participants (250 patients and caregivers each) in this study. The following results were found for patients and caregivers, respectively: 74.8% and 63.6% felt their number of medications was high, 64.4% and 55.6% desired to reduce their medications, 70.4% and 60.8% were concerned about medication discontinuation, 63.2% and 61.2% had a good understanding of their medications, 77.6% and 76.4% were willing to be well informed, and 79.6% and 72% wanted to reduce the number of medications if medically feasible. Patients and caregivers commonly agreed to the burden of the number of medications they were taking, and were willing to reduce the number of medications if the doctor said it was possible. Doctors should consider this information during the deprescribing process, and promote deprescription while involving patients and caregivers in the decision-making process.

Attitudes of older adults and their carers towards de-prescribing: A systematic review

AIM

The aim of this systematic review is to explore the attitudes of older adults (≥65 years old) and their carers towards de-prescribing.

METHODS

We identified relevant studies from three databases; MEDLINE, CINAHL and Web of Science. Two reviewers (MS, SS) independently extracted data from each selected study using a standardised self-developed data extraction form. Main findings of the studies were summarised descriptively.

RESULTS

A total of 35 studies were included in the review. Of them, 19 were questionnaire studies, 11 semi-structured interviews, 4 focus groups and 1 study used the nominal group technique approach. Most older adults and their carers were willing to have medication de-prescribed if told to do so by a healthcare professional (HCP). Other factors that increased willingness to de-prescribing included; trust in the HCP, side effects and inconvenience from medications as well as the prospect of follow-up and monitoring during de-prescribing. In contrast, perceived effectiveness, unawareness of lack of benefit, negative expectations of ageing and fear were factors preventing de-prescribing.

CONCLUSION

De-prescribing is an important concept in older people given the harm associated with polypharmacy in this age group. Overall, older adults and their carers are willing to have medication de-prescribed if facilitated by their HCP. However, there remain a few barriers to de-prescribing which may need to be addressed in certain patients, through discussions between older adults/their carers and a HCP, to allow de-prescribing to be more effective.

Continue or not to continue? Attitudes towards deprescribing among community-dwelling older adults in China

Background

Inappropriate prescribing of medications and polypharmacy among older adults are associated with a wide range of adverse outcomes. It is critical to understand the attitudes towards deprescribing—reducing the use of potentially inappropriate medications (PIMs)—among this vulnerable group. Such information is particularly lacking in low - and middle-income countries.

Methods

In this study, we examined Chinese community-dwelling older adults’ attitudes to deprescribing as well as individual-level correlates. Through the community-based health examination platform, we performed a cross-sectional study by personally interviews using the revised Patients’ Attitudes Towards Deprescribing (rPATD) questionnaire (version for older adults) in two communities located in Suzhou, China. We recruited participants who were at least 65 years and had at least one chronic condition and one prescribed medication.

Results

We included 1,897 participants in the present study; the mean age was 73.8 years (SD = 6.2 years) and 1,023 (53.9%) were women. Most of older adults had one chronic disease (n = 1,364 [71.9%]) and took 1–2 regular drugs (n = 1,483 [78.2%]). Half of the participants (n = 947, 50%) indicated that they would be willing to stop taking one or more of their medicines if their doctor said it was possible, and 924 (48.7%) older adults wanted to cut down on the number of medications they were taking. We did not find individual level characteristics to be correlated to attitudes to deprescribing.

Conclusions

The proportions of participants’ willingness to deprescribing were much lower than what prior investigations among western populations reported. It is important to identify the factors that influence deprescribing and develop a patient-centered and practical deprescribing guideline that is suitable for Chinese older adults.

Low health literacy and multiple medications in community-dwelling older adults: a population-based cohort study

OBJECTIVES

Adequate health literacy is important for patients to manage chronic diseases and medications. We examined the association between health literacy and multiple medications in community-dwelling adults aged 50 years and older in England.

DESIGN, SETTINGS AND PARTICIPANTS

We included 6368 community-dwelling people of median age 66 years from the English Longitudinal Study of Ageing. Health literacy was assessed at wave 5 (2010/11) with 4 questions concerning a medication label. Four correct answers were categorised as adequate health literacy, otherwise low. Data on medications were collected at wave 6 (2012/13). To examine the difference in the number of medications between low and adequate health literacy, we used zero-inflated negative binomial regression, estimating odds ratio (OR) for zero medication and incidence rate ratios (IRR) for the number of medications, with 95% CIs. Associations were adjusted for demographic, socioeconomic and health characteristics, smoking and cognitive function. We also stratified the analysis by sex, and age (50-64 and ≥65 years). To be comparable with preceding studies, multinomial regression was fitted using commonly used thresholds of polypharmacy (0 vs 1-4, 5-9, ≥10 medications).

RESULTS

Although low health literacy was associated with a lower likelihood of being medication-free (OR=0.64, 95% CI: 0.45 to 0.91), health literacy was not associated with the number of medications among those at risk for medication (IRR=1.01, 95% CI: 0.96 to 1.05), and this finding did not differ among younger and older age groups or women. Among men, low health literacy showed a weak association (IRR=1.06, 95% CI: 0.99 to 1.14). Multinomial regression models showed graded risks of polypharmacy for low health literacy.

CONCLUSIONS

Although there was no overall association between health literacy and the number of medications, this study does not support the assertion that low health literacy is associated with a notably higher number of medications in men.

How Willing Are Patients or Their Caregivers to Deprescribe: a Systematic Review and Meta-analysis

BACKGROUND

Polypharmacy is associated with the increased use of potentially inappropriate medications, where the risks of medicine use outweigh its benefits. Stopping medicines (deprescribing) that are no longer needed can be beneficial to reduce the risk of adverse events. We summarized the willingness of patients and their caregivers towards deprescribing.

METHODS

A systematic search was conducted in four databases from inception until April 30, 2021 as well as search of citation of included articles. Studies that reported patients' and/or their caregivers' attitude towards deprescribing quantitatively were included. All studies were independently screened, reviewed, and data extracted in duplicates. Patients and caregivers willingness to deprescribe their regular medication was pooled using random effects meta-analysis of proportions.

RESULTS

Twenty-nine unique studies involving 11,049 participants were included. All studies focused on the attitude of the patients towards deprescribing, and 7 studies included caregivers' perspective. Overall, 87.6% (95% CI: 83.3 to 91.4%) patients were willing to deprescribe their medication, based upon the doctors' suggestions. This was lower among caregivers, with only 74.8% (49.8% to 93.8%) willing to deprescribe their care recipients' medications. Patients' or caregivers' willingness to deprescribe were not influenced by study location, study population, or the number of medications they took.

DISCUSSION

Most patients and their caregivers were willing to deprescribe their medications, whenever possible and thus should be offered a trial of deprescribing. Nevertheless, as these tools have a poor predictive ability, patients and their caregivers should be engaged during the deprescribing process to ensure that the values and opinions are heard, which would ultimately improve patient safety. In terms of limitation, as not all studies may published the methods and results of measurement they used, this may impact the methodological quality and thus our findings.

The Association Between e-Health Literacy and Willingness to Deprescribe Among Patients with Chronic Diseases: A Cross-Sectional Study from Jordan

Background: Deprescribing refers to the partnered discontinuation of chronic medications to limit the negative impacts of polypharmacy. Polymedicated patients play a key role in the success of deprescribing efforts. eHealth literacy reflects patients' ability to appraise electronically available health-related information to make informed health care decisions, which partly reflect their desire to deprescribe. Objectives: The current study aimed to explore the relationship between eHealth literacy and willingness to deprescribe among patients with chronic diseases. Additionally, the predictors of willingness to deprescribe were examined. Materials and Methods: This cross-sectional study was conducted among adult patients with chronic diseases in Jordan. An online questionnaire comprising two validated tools, namely the Electronic Health Literacy Scale (eHEALS) and the Revised Patients' Attitudes Toward Deprescribing (rPATD) Questionnaire, was used for data collection. The questionnaire targeted adult patients with chronic medical conditions in Jordan and was posted to social media portals, following a convenience sampling technique. Results: A total of 719 responses were recorded and included in the final analysis. Participants with higher levels of eHealth literacy were more willing to get their medications deprescribed, as indicated by the perceived use of unneeded medications (p = 0.042). Meanwhile, participants with low levels of eHealth literacy were more likely to report fear of missing out on the potential benefits of deprescribed medications (p = 0.003). Other items that were commonly agreed upon by both the low and high eHealth literacy groups, respectively, included desire for dose reduction (p < 0.001, p < 0.001), belief in the lack of effectiveness of some prescribed medications (p < 0.001,p < 0.001), and fear of precipitating side effects (p = 0.001,p = 0.007). Conclusions: The present study highlighted the relationship between eHealth literacy and a number of items reflecting willingness to deprescribe, and these indicators can be used to guide future deprescribing efforts among eligible patients.

Consumer attitudes towards deprescribing: a systematic review and meta-analysis

Background

Harmful and/or unnecessary medication use in older adults is common. This indicates deprescribing (supervised withdrawal of inappropriate medicines) is not happening as often as it should. This study aimed to synthesize the results of the Patients’ Attitudes Towards Deprescribing (PATD) questionnaire (and revised versions).

Methods

Databases were searched from January 2013 to March 2020. Google Scholar was used for citation searching of the development and validation manuscripts to identify original research using the validated PATD, revised PATD (older adult and caregiver versions), and the version for people with cognitive impairment (rPATDcog). Two authors extracted data independently. A meta-analysis of proportions (random-effects model) was conducted with subgroup meta-analyses for setting and population. The primary outcome was the question: “If my doctor said it was possible, I would be willing to stop one or more of my medicines.” Secondary outcomes were associations between participant characteristics and primary outcome and other (r)PATD results.

Results

We included 46 articles describing 40 studies (n = 10,816 participants). The meta-analysis found the proportion of participants who agreed or strongly agreed with this statement was 84% (95% CI 81%–88%) and 80% (95% CI 74%–86%) in patients and caregivers, respectively, with significant heterogeneity (I² = 95% and 77%).

Conclusion

Consumers reported willingness to have a medication deprescribed although results should be interpreted with caution due to heterogeneity. The findings from this study moves toward understanding attitudes toward deprescribing, which could increase the discussion and uptake of deprescribing recommendations in clinical practice.

Barriers and facilitators to reducing anticholinergic burden: a qualitative systematic review

Background Despite common use, anticholinergic medications have been associated with serious health risks. Interventions to reduce their use are being developed and there is a need to understand their implementation into clinical care. Aim of review This systematic review aims to identify and analyse qualitative research studies exploring the barriers and facilitators to reducing anticholinergic burden. Methods Medline (OVID), EMBASE (OVID), CINAHL (EMBSCO) and PsycINFO (OVID) were searched using comprehensive search terms. Peer reviewed studies published in English presenting qualitative research in relation to the barriers and facilitators of deprescribing anticholinergic medications, involving patients, carers or health professionals were eligible. Normalization Process Theory was used to explore and explain the data. Results Of 1764 identified studies, two were eligible and both involved healthcare professionals (23 general practitioners, 13 specialist clinicians and 12 pharmacists). No studies were identified that involved patients or carers. Barriers to collaborative working often resulted in poor motivation to reduce anticholinergic use. Low confidence, system resources and organisation of care also hindered anticholinergic burden reduction. Good communication and relationships with patients, carers and other healthcare professionals were reported as important for successful anticholinergic burden reduction. Having a named person for prescribing decisions, and clear role boundaries, were also important facilitators. Conclusions This review identified important barriers and facilitators to anticholinergic burden reduction from healthcare provider perspectives which can inform implementation of such deprescribing interventions. Studies exploring patient and carer perspectives are presently absent but are required to ensure person-centeredness and feasibility of future interventions.

The role of older patients' goals in GP decision-making about medicines: a qualitative study

BACKGROUND

To optimise medication use in older people, it is recommended that clinicians evaluate evidence on potential benefits and harms of medicines in light of the patients' overall health, values and goals. This suggests general practitioners (GPs) should attempt to facilitate patient involvement in decision-making. In practice this is often challenging. In this qualitative study, we explored GPs' perspectives on the importance of discussing patients' goals and preferences, and the role patient preferences play in medicines management and prioritisation.

METHODS

Semi-structured interviews were conducted with GPs from Australia (n = 32). Participants were purposively sampled to recruit GPs with variation in experience level and geographic location. Transcribed audio-recordings of interviews were coded using Framework Analysis.

RESULTS

The results showed that most GPs recognised some value in understanding older patients' goals and preferences regarding their medicines. Most reported some discussions of goals and preferences with patients, but often this was initiated by the patient. Practical barriers were reported such as limited time during busy consultations to discuss issues beyond acute problems. GPs differed on the following main themes: 1) definition and perception of patients' goals, 2) relationship with the patient, 3) approach to medicines management and prioritisation. We observed that GPs preferred one of three different practice patterns in their approach to patients' goals in medicines decisions: 1) goals and preferences considered lower priority - 'Directive'; 2) goals seen as central - 'Goal-oriented'; 3) goals and preferences considered but not explicitly elicited - 'Tacit'.

CONCLUSIONS

This study explores how GPs differ in their approach to eliciting patients' goals and preferences, and how these differences are operationalised in the context of older adults taking multiple medicines. Although there are challenges in providing care that aligns with patients' goals and preferences, this study shows how complex decisions are made between GPs and their older patients in clinical practice. This work may inform future research that investigates how GPs can best incorporate the priorities of older people in decision-making around medicines. Developing practical support strategies may assist clinicians to involve patients in discussions about their medicines.
