|title=Quantifying cumulative anticholinergic and sedative drug load among US Medicare Beneficiaries.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/33000867
|abstract=Medications with anticholinergic and sedative properties are widely used among older adults despite strong evidence of harm. The drug burden index ([[DBI]]), a pharmacological screening tool, measures these properties across drug classes, and higher [[DBI]] drug exposure ([[DBI]] > 1) has been associated with certain physical function-related adverse events. Our aim was to quantify mean daily [[DBI]] drug exposure among older adults in the United States (US). We screened medications for [[DBI]] properties and operationalized the [[DBI]] for US Medicare claims. We then conducted a retrospective cohort study of a 20% random, nationwide sample of 4 137 384 fee-for-service Medicare beneficiaries aged 66  years (134 757 039 person-months) from January 2013 to December 2016. We measured the monthly distribution based on mean daily [[DBI]], categorized as (a) >0 vs 0 (any use) and (b) 0, 0 < [[DBI]] ≤ 1, 1 < [[DBI]] ≤ 2, and [[DBI]] > 2, and examined temporal trends. We described patient-level factors (eg, demographics, healthcare use) associated with high (>2) vs low (0 < [[DBI]]≤1) [[DBI]] drug exposure. The distribution of the mean daily [[DBI]], aggregated at the month-level, was: 58.1% [[DBI]] = 0, 29.0% 0 < [[DBI]]≤1, 9.3% 1 < [[DBI]]≤2, and 3.7% [[DBI]] > 2. Predictors of high monthly [[DBI]] drug exposure ([[DBI]] > 2) included certain indicators of increased healthcare use (eg, high number of drug claims), white race, younger age, frailty, and a psychosis diagnosis code. The predictors of high [[DBI]] drug exposure can inform discussions between patients and providers about medication appropriateness and potential de-prescribing. Future Medicare-based studies should assess the association between the [[DBI]] and adverse events.

|title=Drug Burden Index and Cognitive and Physical Function in Aged Care Residents: A Longitudinal Study.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/32736845
|abstract=Anticholinergic/antimuscarinic and sedative medications (eg, benzodiazepines) have been found to be associated with poorer cognitive and physical function and mobility impairment in older age. However, previous studies were mostly conducted among community-dwelling older individuals and had often a cross-sectional design. Accordingly, our aim was to examine longitudinal associations between cumulative exposure to anticholinergic and sedative medications and cognitive and physical function among residents from aged care homes. Longitudinal study. A total of 4624 residents of Dutch aged care homes of whom data were collected between June 2005 and April 2014. Outcome measures were collected with the Long-Term Care Facilities assessment from the international Residential Assessment Instrument (interRAI-LTCF) and included the Cognitive Performance Scale, the Activities of Daily Living (ADL) Hierarchy scale, a timed 4-meter walk test, distance walked, hours of physical activity, and days being outside. Cumulative exposure to anticholinergic and sedative medications was calculated with the Drug Burden Index ([[DBI]]), a linear additive pharmacological dose-response model. Associations were examined with linear mixed models to take the potential dependence of observations into account (ie, data were collected at repeated assessment occasions of residents who were clustered in aged care homes). Analyses were adjusted for sex, age, dementia, comorbidity (neurological, psychiatric, cardiovascular, oncological, and pulmonary), fractures, depressive symptoms, and medications excluded from the [[DBI]]. We observed significant longitudinal associations between a higher [[DBI]] and poorer ADLs, fewer hours of physical activity, and fewer days being outside. We found no significant longitudinal association between a higher [[DBI]] and poorer cognitive function. Over time, cumulative exposure to anticholinergic and sedative medications is associated with poorer physical but not cognitive function in aged care residents. Careful monitoring of aged care residents with high cumulative anticholinergic and sedative medication exposure is needed.

|title=Using the Drug Burden Index to identify older adults at highest risk for medication-related falls.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/32532276
|abstract=The Drug Burden Index ([[DBI]]) was developed to assess patient exposure to medications associated with an increased risk of falling. The objective of this study was to examine the association between the [[DBI]] and medication-related fall risk. The study used a retrospective cohort design, with a 1-year observation period. Participants (n = 1562) were identified from 31 community pharmacies. We examined the association between [[DBI]] scores and four outcomes. Our primary outcome, which was limited to participants who received a medication review, indexed whether the review resulted in at least one medication-related recommendation (e.g., discontinue medication) being communicated to the participant's health care provider. Secondary outcomes indexed whether participants in the full sample: (1) screened positive for fall risk, (2) reported 1  falls in the past year, and (3) reported 1  injurious falls in the past year. All outcome variables were dichotomous (yes/no). Among those who received a medication review (n = 387), the percentage of patients receiving at least one medication-related recommendation ranged from 10.2% among those with [[DBI]] scores of 0 compared to 60.2% among those with [[DBI]] scores ≥1.0 (Chi-square (4)=42.4, p < 0.0001). Among those screened for fall risk (n = 1058), [[DBI]] scores were higher among those who screened positive compared to those who did not (Means = 0.98 (SD = 1.00) versus 0.59 (SD = 0.74), respectively, p < 0.0001). Our findings suggest that the [[DBI]] is a useful tool that could be used to improve future research and practice by focusing limited resources on those individuals at greatest risk of medication-related falls.

|title=Impact of STEADI-Rx: A Community Pharmacy-Based Fall Prevention Intervention.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/32315461
|abstract=To evaluate the effects of a community pharmacy-based fall prevention intervention (STEADI-Rx) on the risk of falling and use of medications associated with an increased risk of falling. Randomized controlled trial. A total of 65 community pharmacies in North Carolina (NC). Adults (age ≥65 years) using either four or more chronic medications or one or more medications associated with an increased risk of falling (n = 10,565). Pharmacy staff screened patients for fall risk using questions from the Stopping Elderly Accidents, Deaths, and Injuries (STEADI) algorithm. Patients who screened positive were eligible to receive a pharmacist-conducted medication review, with recommendations sent to patients' healthcare providers following the review. At intervention pharmacies, pharmacy staff used standardized forms to record participant responses to screening questions and information concerning the medication reviews. For participants with continuous Medicare Part D/NC Medicaid coverage (n = 3,212), the Drug Burden Index ([[DBI]]) was used to assess exposure to high-risk medications, and insurance claims records for emergency department visits and hospitalizations were used to assess falls. Among intervention group participants (n = 4,719), 73% (n = 3,437) were screened for fall risk. Among those who screened positive (n = 1,901), 72% (n = 1,373) received a medication review; and 27% (n = 521) had at least one medication-related recommendation communicated to their healthcare provider(s) following the review. A total of 716 specific medication recommendations were made. [[DBI]] scores decreased from the pre- to postintervention period in both the control and the intervention group. However, the amount of change over time did not differ between these two groups (P = .66). Risk of falling did not change between the pre- to postintervention period or differ between groups (P = .58). We successfully implemented STEADI-Rx in the community pharmacy setting. However, we found no differences in fall risk or the use of medications associated with increased risk of falling between the intervention and control groups. J Am Geriatr Soc 68:1778-1786, 2020.

|title=Association of Drug Burden Index with grip strength, timed up and go and Barthel index activities of daily living in older adults with intellectual disabilities: an observational cross-sectional study.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/31234775
|abstract=Drug Burden Index ([[DBI]]), a measure of exposure to medications with anticholinergic and sedative activity, has been associated with poorer physical function in older adults in the general population. While extensive study has been conducted on associations between [[DBI]] and physical function in older adults in the general population, little is known about associations in older adults with intellectual disabilities (ID). This is the first study which aims to examine the association between [[DBI]] score and its two sub-scores, anticholinergic and sedative burden, with two objective measures of physical performance, grip strength and timed up and go, and a measure of dependency, Barthel Index activities of daily living, in older adults with ID. Data from Wave 2 (2013/2014) of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA) was analysed. Analysis of Covariance (ANCOVA) was used to detect associations and produce adjusted means for the physical function and dependency measures with respect to categorical [[DBI]] scores and the anticholinergic and sedative sub-scores (DBA and DBS). After adjusting for confounders (age, level of ID, history of falls, comorbidities and number of non-[[DBI]] medications, Down syndrome (grip strength only) and gender (timed up and go and Barthel Index)), neither grip strength nor timed up and go were significantly associated with [[DBI]], DBA or DBS score > 0 (p > 0.05). Higher dependency in Barthel Index was associated with DBS exposure (p < 0.001). [[DBI]], DBA or DBS scores were not significantly associated with grip strength or timed up and go. This could be as a result of established limitations in physical function in this cohort, long-term exposure to these types of medications or lifelong sedentary lifestyles. Higher dependency in Barthel Index activities of daily living was associated with sedative drug burden, which is an area which can be examined further for review.

|title=Impact of drug burden index on adverse health outcomes in Irish community-dwelling older people: a cohort study.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/31035946
|abstract=The Drug Burden Index ([[DBI]]) quantifies exposure to medications with anticholinergic and/or sedative effects. A consensus list of [[DBI]] medications available in Ireland was recently developed for use as a [[DBI]] tool. The aim of this study was to validate this [[DBI]] tool by examining the association of [[DBI]] score with important health outcomes in Irish community-dwelling older people. This was a cohort study using data from The Irish Longitudinal Study on Ageing (TILDA) with linked pharmacy claims data. Individuals aged ≥65 years participating in TILDA and enrolled in the General Medical Services scheme were eligible for inclusion. [[DBI]] score was determined by applying the [[DBI]] tool to participants' medication dispensing data in the year prior to outcome assessment. [[DBI]] score was recoded into a categorical variable [none (0), low (> 0 and < 1), and high (≥1)]. Outcome measures included any Activities of Daily Living (ADL) impairment, any Instrumental Activities of Daily Living (IADL) impairment, any self-reported fall in the previous 12 months, any frailty criterion met (Fried Phenotype measure), quality of life (QoL) score (CASP-19 [Control Autonomy Self-realisation Pleasure] measure), and healthcare utilisation (any hospital admission and any emergency department (ED) visit) in the previous 12 months. Statistical analyses included multivariate logistic and linear regression models controlling for potential confounders. 61.3% (n = 1946) of participants received at least one [[DBI]] prescription in the year before their outcome assessment. High [[DBI]] exposure ([[DBI]] score ≥ 1) vs none was significantly associated with impaired function (ADL impairment adjusted OR 1.89, 95% CI 1.25, 2.88; IADL impairment adjusted OR 2.97, 95% CI 1.91, 4.61), self-reported falls (adjusted OR 1.50, 95%CI 1.03, 2.18), frailty (adjusted OR 1.74, 95% CI 1.14, 2.67), and reduced QoL (β = - 1.84, 95%CI -3.14, - 0.54). There was no significant association between [[DBI]] exposure and healthcare utilisation. The findings validate the use of the [[DBI]] tool for predicting risk of functional impairment, falls, frailty and reduced QoL in older people in Ireland, and may be extended to other European countries. Integration of this tool into routine practice may be an appropriate step forward to improve outcomes in older people.

|title=Dietary Balance Index-07 and the Risk of Anemia in Middle Aged and Elderly People in Southwest China: A Cross Sectional Study.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/29385057
|abstract=A balanced diet is essential to achieve and maintain good health. In this study, we assessed diet quality of middle aged and elderly people based on Chinese Diet Balance Index-07 ([[DBI]]-07) and explored the associations between [[DBI]]-07 and anemia. Data analyzed for this study was from the 2010-2012 National Nutrition and Health Survey in Yunnan province, southwest China ([i]n[/i] = 738, aged 50-77 years). Dietary recalls over there consecutive days were done in a face-to-face interview. The scores of [[DBI]]-07 for each component and three [[DBI]]-07 indicators ((Lower Bound Score (LBS), Higher Bound Score (HBS), Diet Quality Distance (DQD)) were calculated according to compliance with the Dietary Guidelines for Chinese residents. Hemoglobin (Hb) concentration was determined using the cyanmethemoglobin method. Univariate and multivariate linear regression models were used to explore the associations between [[DBI]]-07 indicators and anemia, as well as scores of [[DBI]]-07 components and Hb level. The sample included 336 men and 402 women. Inadequate intakes of vegetables, fruits, dairy, soybean, eggs, fish and excessive intakes of cereals, meat, cooking oil, salt were both common. 91.3% of the participants had moderate or high levels of inadequate food intake, while 37.7% had moderate or high levels of excessive food intake. The mean Hb was 14.2 ± 1.7 g/dL, with a prevalence of anemia of 13.0%. Subjects with high LBS and DQD were more likely to be anemic (all [i]p[/i] < 0.05). After adjustment for potential confounders, there were positive correlations between Hb level and the intakes of vegetables and soybean (β  = 1.04, [i]p[/i] < 0.01; β  = 0.82, [i]p[/i] = 0.04). In conclusion, dietary imbalance and anemia are common in middle aged and elderly population in southwest China and inadequate intakes of vegetables and soybean may increase the risk of anemia.

|title=Effects of Changes in Number of Medications and Drug Burden Index Exposure on Transitions Between Frailty States and Death: The Concord Health and Ageing in Men Project Cohort Study.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/26782856
|abstract=To investigate the effects of number of medications and Drug Burden Index ([[DBI]]) on transitions between frailty stages and death in community-dwelling older men. Cohort study. Sydney, Australia. Community-dwelling men aged 70 and older (N=1,705). Self-reported questionnaires and clinic visits were conducted at baseline and 2 and 5 years. Frailty was assessed at all three waves according to the modified Fried frailty phenotype. The total number of regular prescription medications and [[DBI]] (a measure of exposure to sedative and anticholinergic medications) were calculated over the three waves. Data on mortality over 9 years were obtained. Multistate modeling was used to characterize the transitions across three frailty states (robust, prefrail, frail) and death. Each additional medication was associated with a 22% greater risk of transitioning from the robust state to death (adjusted 95% confidence interval (CI)=1.06-1.41). Every unit increase in [[DBI]] was associated with a 73% greater risk of transitioning from the robust state to the prefrail state (adjusted 95% CI=1.30-2.31) and a 2.75 times greater risk of transitioning from the robust state to death (adjusted 95% CI=1.60-4.75). There was no evidence of an adjusted association between total number of medications or [[DBI]] and the other transitions. Although the possibility of confounding by indication cannot be excluded, additional medications were associated with greater risk of mortality in robust community-dwelling older men. Greater [[DBI]] was also associated with greater risk of death and transitioning from the robust state to the prefrail state.

|abstract=Determine the association between different measures of drug exposure such as an increased Drug Burden Index ([[DBI]]) and a higher Anticholinergic Risk Scale (ARS) score in vulnerable elders and risk of readmission to the hospital. The study is a retrospective cohort comparing ARS and [[DBI]] between patients readmitted and not readmitted to the hospital within 30 days of initial admission. Data collected included drugs considered to have anticholinergic, sedative, or both types of properties (Appendix 1), medication strengths, doses per day, patient age, Vulnerable Elders Survey (VES-13) score upon admission, patient diagnoses, and rates of admission. Nonprofit, 838-bed, regional health system of four hospitals. Patients were included in the study if they were admitted to a hospital floor, were 65 years of age or older, were assessed using VES-13, and did not have routinely visiting family to engage them as observed by floor nurses. None; retrospective study. Readmission rate. The mean difference in [[DBI]] and ARS scores were higher in the readmitted group. Hydrocodone and hydroxyzine were the most commonly used drugs in the readmitted group that were considered when determining [[DBI]]. There is a role for screening and clinical intervention in vulnerable elders using [[DBI]] and ARS to help identify those at greatest risk for readmission to the hospital.
