[Vaccination status and factors associated with pneumococcal vaccination in geriatric short-stay care]

Nearly two-thirds of geriatric short-stay patients were eligible for pneumococcal vaccination. Among patients eligible for vaccination, less than 5 % had received at least one injection of pneumococcal vaccine on admission. We found no modifiable factors associated with vaccination status, but several avenues for improving vaccination coverage.

[Validation of a method for detecting hospitalizations for falls related to adverse drug reactions in geriatric departments]

Fall is one of the five main causes of drug-related hospital admissions (DRA) in France. A standardized chart review method, to identify DRA adapted to elderly patients, has recently been developed by Thevelin et al. Our first aim was to assess the reliability of this method for detecting DRA for falls in elderly subjects. Our second aim was to assess the feasibility of this method and to evaluate its reliability for assessing causality, the contribution of DRA to hospitalization, and the avoidability of DRAs in elderly patients hospitalized for a medication-related fall. A retrospective observational study was conducted on 16 patient cases admitted to the hospital for falls in May 2022, in the geriatric department of a French university hospital. Six healthcare professionals (pharmacists, pharmacologists, and geriatricians) assessed a method for detecting DRA individually and then in multidisciplinary pairs of raters. Inter-rater agreement (individually and in pairs) was assessed for DRA detection, causality, avoidability, and contribution of the DRA to hospitalization. A κ > 0,4 was considered a satisfactory threshold for agreement. The mean age was 86 years. When the assessment was done individually, detection of DRA-related hospitalizations (κ = 0,46; p < ,001), and DRA contribution to hospitalization (κ = 0,50; p < ,001) were moderately concordant. The causality assessment (κ = 0,09; p = 0,24) did not agree, and the avoidability assessment (κ = 0,63; p < ,001) agreed substantially. When the evaluation was done in pairs, detection of DRA-related hospitalizations (κ = 0,47; p < ,001) was moderately concordant between pairs. Avoidability assessment (κ = 0,79; p < ,001) concurred substantially. The assessment of causality (κ = 0,29; p = 0,01) and DRA contribution to hospitalization (κ = 0,38; p < .001) agreed fairly well. This study validated, individually and in pairs, the reliability of the method to identify DRA in the context of falls. This method will be of great use in research and epidemiological studies.

Implementation of clinical medication review in a geriatric ward to reduce potentially inappropriate prescriptions among older adults

PURPOSE

The impact of several pharmaceutical interventions to reduce the use of potentially inappropriate medications (PIMs) and potentially omitted medications (POMs) has been recently studied. We aimed to determine whether clinical medication review (CMR) (i.e. a systematic and patient-centred clinical assessment of all medicines currently taken by a patient) performed by a geriatrician and a pharmacist added to standard pharmaceutical care (SPC) (i.e. medication reconciliation and regular prescription review by the pharmacist) resulted in more appropriate prescribing compared to SPC among older inpatients.

METHODS

A retrospective observational single-centre study was conducted in a French geriatric ward. Six criteria for appropriate prescribing were chosen: the number of PIMs and POMs as defined by the STOPP/STARTv2 list, the total number of drugs prescribed, the number of administrations per day and the number of psychotropic and anticholinergic drugs. These criteria were compared between CMR and SPC group using linear and logistic regression models weighted on propensity scores.

RESULTS

There were 137 patients included, 66 in the CMR group and 71 in the SPC group. The mean age was 87 years, the sex ratio was 0.65, the mean number of drugs prescribed was 9, the mean MMSE was 21 and at admission 242 POMs, and 363 PIMs were prescribed. Clinical medication review did not reduce the number of PIMs at discharge compared to SPC (beta = - 0.13 [- 0.84; 0.57], p = 0.71) nor did it reduce the number of drugs prescribed (p = 0.10), the number of psychotropic drugs (p = 0.17) or the anticholinergic load (p = 0.87). Clinical medication review resulted in more POMs being prescribed than in standard pharmaceutical care (beta = - 0.39 [- 0.72; - 0.06], p = 0.02). Cardiology POMs were more implemented in the medication review group (p = 0.03).

CONCLUSION

Clinical medication review did not reduce the number of PIMs but helped clinicians introduce underused drugs, especially cardiovascular drugs, which are known to be associated with morbidity and mortality risk reduction.

Adverse Effects of Anticholinergic Drugs on Cognition and Mobility: Cutoff for Impairment in a Cross-Sectional Study in Young-Old and Old-Old Adults

BACKGROUND

Drugs with anticholinergic properties are commonly prescribed in older adults despite growing evidence of their adverse outcomes. Several issues regarding these detrimental effects remain unresolved, such as the putative existence of a threshold above which anticholinergic drug consumption impairs cognitive or mobility performance.

OBJECTIVES

We aimed to investigate the number of anticholinergic drugs and the anticholinergic burden that leads to mobility or cognitive impairment and compare the effects in community-dwelling older adults in two age groups ("young-old" 55-74 vs. "old-old" ≥ 75 years).

METHODS

In a cross-sectional study, we identified drugs with anticholinergic (antimuscarinic) properties using the Anticholinergic Drug Scale. Cognition was assessed using the Mini Mental State Examination (MMSE) and the Trail Making Test (TMT-A and TMT-B), and mobility was assessed using the Timed Up and Go (TUG) test.

RESULTS

The study population consisted of 177 volunteers, 114 of whom were classed as young-old and 63 were classed as old-old adults. Despite the lack of cutoff values for impaired outcomes in young-old adults, impaired MMSE were significantly more numerous in users than in nonusers of anticholinergic drugs. In old-old adults, receiver operating characteristic (ROC) curve analysis indicated that taking a single anticholinergic drug per day was associated with impaired TMT-B completion time, TMT difference score (B-A), and TUG scores. The cutoff for anticholinergic burden was also one for these same outcomes. Based on these cutoff values, multivariate logistic regressions in old-old adults showed that the increased risk of impaired cognition and mobility was independent of confounding factors, including comorbidities. They also suggested that anticholinergic drugs would affect mobility through executive functions.

CONCLUSIONS

Drugs with anticholinergic (antimuscarinic) properties are associated with cognitive impairment in individuals as young as 55 years, and only one such drug per day, regardless of its anticholinergic burden, is associated with both impaired cognition and impaired mobility in old-old adults. Therefore, wherever possible, clinicians should avoid prescribing drugs with anticholinergic properties.

ANTICHOLINERGIC DRUGS: CUT-OFF FOR IMPAIRED COGNITION AND MOBILITY IN SENIORS

Background and Objectives: Anticholinergic drugs are commonly prescribed in older adults despite growing evidence of their adverse outcomes. We aimed to improve knowledge about deleterious effects of anticholinergic drugs on both cognition and mobility, in particular whether there is a threshold value for the number of anticholinergic drugs or for the anticholinergic burden leading to mobility or cognitive impairment. Methods: 177 community-dwelling individuals aged 55 years or over, with a fall history in the previous year, took part in the study. Anticholinergic drugs were identified using the Anticholinergic Drug Scale (ADS), and global cognition and mobility were assessed using the Mini Mental State Examination (MMSE) and the Time-Up-and-Go (TUG) test, respectively. Results: ROC (Receiver Operating Characteristics) curve analysis indicated that consumption of a single anticholinergic drug per day was a risk factor for impaired MMSE (p < .05) and TUG scores (p < .05). There was also a cut-off of anticholinergic burden of one for impaired MMSE scores (p < .05). Logistic regressions showed that impaired cognition induced by anticholinergic drugs were independent of confounding factors including comorbidities, while impaired mobility would be influenced by age and cardiac comorbidities. Conclusion: Daily consumption of a single anticholinergic drug, regardless of its anticholinergic burden, impairs both cognition and mobility community-dwelling seniors. Alternative solutions to anticholinergic drug prescription should thus be considered whenever possible.

Polypharmacy Cut-Off for Gait and Cognitive Impairments

BACKGROUND

Polypharmacy is a well-established risk factor for falls, and these are one of the major health problems that affect the quality of life as people age. However, the risk of mobility and cognitive impairments consecutive to polypharmacy has been little addressed, despite the association between these adverse outcomes and falls. Moreover, the rare polypharmacy cut-offs were all but one arbitrarily determined.

OBJECTIVE

Studying relationships between polypharmacy and both mobility and cognitive impairments, and statistically determining a cut-off point in the number of medicinal molecule beyond which polypharmacy has deleterious consequences with respect to mobility and cognitive impairment.

METHODS

We enrolled 113 community-dwelling adults aged 55 years and older with a fall history, with or without injury, in the previous year. We carefully collected information about daily medicinal molecules taken. We assessed basic mobility and global cognition with the Time-Up-and-Go and the Montreal Cognitive Assessment (MoCA) test, respectively (clinicaltrials.gov NCT02292316).

RESULTS

Timed-Up and Go test and MoCA scores were both significantly correlated with the number of molecule, used. Receiver Operating Characteristic curves indicate, with high prediction (p < 0.002), that daily consumption of five or more molecules is associated with risk for both impaired mobility and global cognition. These relationships were independent of the number of comorbidities and of the pharmacological class.

CONCLUSION

Community-dwelling adults aged 55 years and older who take five or more daily medicinal molecules are at high risk for both mobility and cognitive impairments. Physicians and patients should be aware of these new findings, especially when there are multiple prescribers involved in the care of the patient.
