The association between geriatric treatment and 30-day readmission risk among medical inpatients aged ≥75 years with multimorbidity.

BACKGROUND: Readmission to hospital is frequent among older patients and reported as a post-discharge adverse outcome. The effect of treatment in a geriatric ward for acutely admitted older patients on mortality and function is well established, but less is known about the possible influence of such treatment on the risk of readmission, particularly in the oldest and most vulnerable patients. Our aim was to assess the risk for early readmission for multimorbid patients > 75 years treated in a geriatric ward compared to medical wards and to identify risk factors for 30-day readmissions. METHODS: Prospective cohort study of patients acutely admitted to a medical department at a Norwegian regional hospital. Eligible patients were community-dwelling, multimorbid, receiving home care services, and aged 75+. Patients were consecutively included in the period from 1 April to 31 October 2012. Clinical data were retrieved from the referral letter and medical records. RESULTS: We included 227 patients with a mean (SD) age of 86.0 (5.7) years, 134 (59%) were female and 59 (26%) were readmitted within 30 days after discharge. We found no statistically significant difference in readmission rate between patients treated in a geriatric ward versus other medical wards. In adjusted Cox proportional hazards regression analyses, lower age (hazard ratio (95% confidence interval) 0.95 (0.91-0.99) per year), female gender (2.17 (1.15-4.00)) and higher MMSE score (1.03 (1.00-1.06) per point) were significant risk factors for readmission. CONCLUSIONS: Lower age, female gender and higher cognitive function were the main risk factors for 30-day readmission to hospital among old patients with multimorbidity. We found no impact of geriatric care on the readmission rate.

Association between psychotropic drug use and handgrip strength in older hospitalized patients.

PURPOSE: Handgrip strength is an indicator of frailty and longevity in older adults. The association between psychotropic drug use and handgrip strength in older hospitalized patients was investigated in this study. METHODS: A total of 488 patients were included in this retrospective cross-sectional study, 333 women and 155 men, from two different cohorts of older (mean age 84 years) hospitalized in-patients. We used multiple linear regression models to explore the association between psychotropic drug use and handgrip strength. We adjusted for factors known to affect handgrip strength: Age, gender, body mass index (BMI) and comorbidity (Charlson comorbidity index). RESULTS: Both unadjusted and adjusted analyses showed that psychotropic drug use was associated with handgrip strength (ß = - 0.183, p < 0.0001). The relationship was of a linear character, with no clear threshold value, but with the greatest reduction in handgrip strength between zero and two psychotropic drugs. CONCLUSION: An increasing number of psychotropic drugs were significantly associated with reduced handgrip strength in a linearly pattern. Hence, it is timely to question the guided threshold value of avoidance of three or more psychotropic drugs in older people. Psychotropic drug use should be kept as low as possible in treatment of older patients.

Delirium and cognitive impairment among older patients in Norwegian emergency departments. / Delirium og kognitiv svikt blant eldre i norske akuttmottak.

BACKGROUND: Delirium is common and underdiagnosed among patients in hospitals, and is associated with complications, increased mortality, onset of dementia and need for nursing home care. Cognitive impairment from other causes is also common among hospitalised elderly people and is a key risk factor for delirium. Since no relevant prevalence studies have been undertaken in Norwegian hospitals, we investigated the prevalence of delirium among elderly patients in Norwegian emergency departments on World Delirium Awareness Day, 14 March 2018. MATERIAL AND METHOD: We included patients ≥ 75 years who arrived in ten Norwegian emergency departments between 08:00 and 22:00 on that day. We identified delirium and cognitive impairment using the '4AT' screening tool and registered the patients' age and gender and the hospital and department to which they were admitted (internal medicine, surgery, orthopaedics, 'other'). RESULTS: Of 118 included patients, 20 (17 per cent) showed signs of delirium and 36 (30 per cent) showed signs of other forms of cognitive impairment. All hospitals and all categories of departments received patients with signs of delirium and cognitive impairment. INTERPRETATION: Delirium and other forms of cognitive impairment are both common among elderly patients in Norwegian emergency departments. Our results indicate that all hospital departments who treat elderly patients frequently observe these issues. All departments should therefore have routines to identify and deal with patients who suffer from delirium and cognitive impairment.

Can screening tools for potentially inappropriate prescriptions in older adults prevent serious adverse drug events?

PURPOSE: The purpose of the study is to identify and explore risk factors of serious adverse drug events (SADE) and SADE-related admissions in acutely hospitalized multimorbid older adults and assess whether these could have been prevented by adherence to the prescription tools Screening Tool of Older Persons' Prescriptions (STOPP) and The Norwegian General Practice (NORGEP) criteria. METHODS: Cross-sectional study of acutely admitted patients to a medical department in a Norwegian regional hospital. Eligible patients were community-dwelling, receiving home care services, and aged 75+, with ≥ 3 chronic diseases. Medications and information regarding the admission were retrieved from the referral letter and medical records, while an expert panel identified SADE using the Common Terminology Criteria for Adverse Events and SADE-related admissions. RESULTS: We included 232 patients. Mean (SD) age was 86 (5.7) years, 137 (59%) were female, 121 (52%) used 5-9 drugs whereas 65 (28%) used ≥ 10. We identified SADEs in 72 (31%) of the patients, and in 49 (68%) of these cases, the SADE was considered to cause the hospital admission. A low body mass index (BMI) and a high Cumulative Illness Rating Scale-Geriatrics (CIRS-G) score were independent risk factors for SADEs. Among the SADEs identified, 32 (44%) and 11 (15%) were preventable by adherence to STOPP and NORGEP, respectively. CONCLUSIONS: We found a high prevalence of SADE leading to hospitalization. Risk factors for SADE were high CIRS-G and low BMI. STOPP identified more SADEs than NORGEP, but adherence to the prescription tools could only to a limited degree prevent SADEs in this patient group.

Physical function of elderly patients with multimorbidity upon acute hospital admission versus 3 weeks post-discharge.

PURPOSE: To evaluate the change in activities of daily living, grip strength and functional mobility in very old patients >75 years old with multimorbidity upon admission to hospital versus 3 weeks after discharge. A second aim was to explore which baseline variables could predict personal activities of daily living 3 weeks after discharge. METHODS: This prospective cohort study included 115 home-dwelling older adults (mean 86 years, standard deviation 5.9). Participants were measured with the Timed Up and Go, grip strength and Barthel Index in hospital (T1) and 3 weeks after discharge (T2). RESULTS: After 3 weeks, the participants had significantly improved their activities of daily living, mobility and muscle strength, but were still physically reduced compared to reference values for age-matched elderly home dwellers and were at high risk of falls and further loss of independence. In the multivariate regression analysis, baseline cognitive function and mobility were independently associated with Barthel Index at T2 and explained 47% of the variance three weeks after discharge. CONCLUSIONS: Our findings highlight the importance of applying performance-based assessments for elderly in hospital. The result indicates that frail old adults acutely admitted to hospital are in need of rehabilitation 3 weeks after hospitalization. Implications for Rehabilitation Older people with multimorbidity improve their physical function 3 weeks after hospitalization. Nevertheless, they still are physically reduced with respect to reference values for age-matched elderly home dwellers and far below the cutoff score for their risk of falls, continued health decline and loosing their independence. The results imply that older people with multimorbidity are in need of early rehabilitation program during hospitalization and after hospitalization. The use of performance-based measurements enables us to identify older adults at highest risk of decline in health and function and is a key of identifying frail older peoples need for rehabilitation. The Time up and Go test, Grip Strength test and the Barthel Index are considered to complement each other and regarded as useful assessments for frail older people in hospital with acute illness.

Clinical impact of potentially inappropriate medications during hospitalization of acutely ill older patients with multimorbidity.

OBJECTIVE: To identify potentially inappropriate medications (PIMs), to compare drug changes between geriatric and other medical wards, and to investigate the clinical impact of PIMs in acutely hospitalized older adults. SETTING AND SUBJECTS: Retrospective study of 232 home-dwelling, multimorbid older adults (aged ≥75 years) acutely admitted to Vestfold Hospital Trust, Norway. MAIN OUTCOME MEASURES: PIMs were identified by Norwegian general practice (NORGEP) criteria and Beers' 2012 criteria. Clinical correlates were laboratory measures, functional and mental status, physical frailty, and length of stay. RESULTS: Mean (SD) age was 86 (5.7) years, and length of stay was 6.5 (4.8) days. During the stay, the mean number of drugs used regularly changed from 7.8 (3.6) to 7.9 (3.6) (p = 0.22), and drugs used pro re nata (prn) changed from 1.4 (1.6) to 2.0 (1.7) (p < 0.001). The prevalence of any PIM changed from 39.2% to 37.9% (p = 0.076), while anticholinergics and benzodiazepines were reduced significantly (p ≤ 0.02). The geriatric ward reduced drug dosages (p < 0.001) and discontinued PIMs (p < 0.001) significantly more often than other medical wards. No relations between number of PIMS and clinical outcomes were identified, but the concomitant use of ≥3 psychotropic/opioid drugs was associated with reduced hand-grip strength (p ≤ 0.012). CONCLUSION: Hospitalization did not change polypharmacy or PIMs. Drug treatment was more appropriate on the geriatric than other medical wards. No clinical impact of PIMs was observed, but prescribers should be vigilant about concomitant prescription of ≥3 psychotropics/opioids. KEY POINTS: Acute hospitalization of older patients with multimorbidity did not increase polypharmacy or potentially inappropriate medications. Prescription of anticholinergics and benzodiazepines was significantly reduced. The geriatric ward reduced drug dosages and discontinued potentially inappropriate medications more frequently than the other medical wards.

"Natural course" of disease in patients with metastatic castrate-resistant prostate cancer: Survival and prognostic factors without life-prolonging treatment.

OBJECTIVE: The aim of this study was to determine survival and prognostic factors in unselected patients with metastatic castrate-resistant prostate cancer (mCRPC), who never received life-prolonging treatment. MATERIALS AND METHODS: The study was a retrospective analysis of a consecutive sample of patients with mCRPC seen at the urological unit of a local hospital from 2000 to 2005, their mCRPC diagnosis based on rising prostate-specific antigen (PSA) during androgen depletion treatment (ADT). RESULTS: Median overall survival was 12.3 months (range 0.2-108 months), the 3 year survival was 16.9% (95% confidence interval 0.11-0.24) and two patients were alive at the end of follow-up. Compared to a PSA nadir of greater than 11 µg/l during ADT, a PSA nadir of less than 1 µg/l significantly decreased the risk of death by 71%. A PSA doubling time less than 1.6 months during the early phase of mCRCP almost tripled the risk of death compared to a PSA doubling time longer than 3 months. Alkaline phosphatase serum levels and hemoglobin levels within the normal range indicated a favorable prognosis. CONCLUSIONS: The "natural course" of mCRPC varies without life-prolonging treatment along with PSA nadir during ADT, PSA doubling time, alkaline phosphatase and hemoglobin level at mCRPC diagnosis. 3-year survival or longer is observed in 16.9% of patients. In clinical intervention trials among mCRPC patients, all known prognostic factors should be taken into account during the randomization process and during survival analyses.
