RESUMO

PURPOSE: Potentially inappropriate medications (PIMs) are associated with falls, hospitalization, and cognitive decline. Few studies have investigated the association between PIMs related to cognitive impairment (PIMCog) and mortality in dementia or mild cognitive impairment (MCI). METHODS: This was a retrospective observational study. Patients diagnosed with MCI or dementia (DSM-IV criteria) presenting to a tertiary-referral memory clinic from 2013 to 2019 were eligible. The primary outcome was all-cause death. Secondary outcomes were vascular death and non-vascular death. The primary exposure variable of interest was PIMCog, defined as any medication in the Beers 2015 or STOPP criteria, classified as potentially inappropriate for patients with cognitive impairment. Anticholinergic burden was measured using the anticholinergic cognitive burden (ACB) scale. Polypharmacy was defined as ≥ 5 medications. Cox proportional hazard models were used to calculate hazard ratios (HRs) and 95% confidence intervals (95% CIs). RESULTS: Four hundred eighteen patients were included (n = 261 dementia, n = 157 MCI). The median age was 79 (interquartile range [IQR] 74-82) and median follow-up was 809 days (IQR 552-1571). One or more PIMCog was prescribed in 141 patients (33.4%). PIMCog use was associated with all-cause mortality after adjustment for age, sex, dementia severity, Charlson's Co-morbidity Index, chronic obstructive pulmonary disease, congestive cardiac failure, and peripheral vascular disease (HR 1.96, 95% CI 1.24-3.09). PIMCog use was associated with vascular death (HR 3.28, 95% CI 1.51-7.11) but not with non-vascular death (HR 1.40 95% CI 0.78-2.52). CONCLUSION: PIMCog use in patients with cognitive impairment is high. It is independently associated with all-cause mortality and vascular death. This is a potential modifiable risk factor for death in this patient cohort. Further research is required to independently validate this finding.

RESUMO

OBJECTIVES: Multifactorial interventions, which involve assessing an individual's risk of falling and providing treatment or onward referral, require coordination across settings. Using a mixed-methods design, we aimed to develop a process map to examine onward referral pathways following falls risk assessment in primary care. SETTING: Primary care fall risk assessment clinics in the South of Ireland. PARTICIPANTS: Focus groups using participatory mapping techniques with primary care staff (public health nurses (PHNs), physiotherapists (PT),and occupational therapists (OT)) were conducted to plot the processes and onward referral pathways at each clinic (n=5). METHODS: Focus groups were analysed in NVivo V.12 using inductive thematic analysis. Routine administrative data from January to March 2018 included details of client referrals, assessments and demographics sourced from referral and assessment forms. Data were analysed in Stata V.12 to estimate the number, origin and focus of onward referrals and whether older adults received follow-up interventions. Quantitative and qualitative data were analysed separately and integrated to produce a map of the service. RESULTS: Nine staff participated in three focus groups and one interview (PHN n=2; OT n=4; PT n=3). 85 assessments were completed at five clinics (female n=69, 81.2%, average age 77). The average number of risk factors was 5.4 out of a maximum of 10. Following assessment, clients received an average of three onward referrals. Only one-third of referrals (n=135/201, 33%) had data available on intervention receipt. Primary care staff identified variations in how formally onward referrals were managed and barriers, including a lack of client information, inappropriate referral and a lack of data management support. CONCLUSION: Challenges to onward referral manifest early in an integrated care pathway, such as clients with multiple risk factors sent for initial assessment and the lack of an integrated IT system to share information across settings.

RESUMO

The "surprise question" (SQ) predicts the need for palliative care. Its predictive validity for adverse healthcare outcomes and its association with frailty among older people attending the emergency department (ED) are unknown. We conducted a secondary analysis of a prospective study of consecutive patients aged ≥70 attending a university hospital's ED. The SQ was scored by doctors before an independent comprehensive geriatric assessment (CGA). Outcomes included length of stay (LOS), frailty determined by CGA and one-year mortality. The SQ was available for 191 patients, whose median age was 79 ± 9. In all, 56/191 (29%) screened SQ positive. SQ positive patients were frailer; the median clinical frailty score was 6/9 (compared to 4/9, p < 0.001); they had longer LOS (p = 0.008); and they had higher mortality (p < 0.001). Being SQ positive was associated with 2.6 times greater odds of admission and 8.9 times odds of frailty. After adjustment for age, sex, frailty, co-morbidity and presenting complaint, patients who were SQ positive had significantly reduced survival times (hazard ratio 5.6; 95% CI: 1.39-22.3, p = 0.015). Almost one-third of older patients attending ED were identified as SQ positive. These were frailer and more likely to be admitted, have reduced survival times and have prolonged LOS. The SQ is useful to quickly stratify older patients likely to experience poor outcomes in ED.
