Classifying home care clients' risk of unplanned hospitalization with the resident assessment instrument.

PURPOSE: To identify predictive case finding tools for classifying the risk of unplanned hospitalization among home care clients utilizing the Resident Assessment Instrument-Home Care (RAI-HC), with special interest in the Detection of Indicators and Vulnerabilities for Emergency Room Trips (DIVERT) Scale. METHODS: A register-based, retrospective study based on the RAI-HC assessments of 3,091 home care clients (mean age 80.9 years) in the City of Tampere, Finland, linked with hospital discharge records. The outcome was an unplanned hospitalization within 180 days after RAI-HC assessment. The Area Under the Curve (AUC) and the sensitivity and specificity were determined for the RAI-HC scales: DIVERT, Activities of Daily Living Hierarchy (ADLh), Cognitive Performance Scale (CPS), Changes in Health, End-Stage Diseases, Signs, and Symptoms Scale (CHESS), and Method for Assigning Priority Levels (MAPLe). RESULTS: Altogether 3091 home care clients had a total of 7744 RAI-HC assessments, of which 1658 (21.4%) were followed by an unplanned hospitalization. The DIVERT Scale had an AUC of 0.62 (95% confidence interval 0.61-0.64) when all assessments were taken into account, but its value was poorer in the older age groups (< 70 years: 0.71 (0.65-0.77), 70-79 years: 0.66 (0.62-0.69), 80-89 years: 0.60 (0.58-0.62), ≥ 90 years: 0.59 (0.56-0.63)). AUCs for the other scales were poorer than those of DIVERT, with CHESS nearest to DIVERT. Time to hospitalization after assessment was shorter in higher DIVERT classes. CONCLUSION: The DIVERT Scale offers an approach to predicting unplanned hospitalization, especially among younger home care clients. Clients scoring high in the DIVERT algorithm were at the greatest risk of unplanned hospitalization and more likely to experience the outcome earlier than others.

Risk factors of readmission after geriatric hospital care: An interRAI-based cohort study in Finland.

PURPOSE: To identify risk factors for readmission after geriatric hospital care. METHODS: A retrospective cohort study of 1,167 community-dwelling patients aged ≥70 years who were hospitalised in two geriatric hospitals and discharged to their homes over a three-year period. We combined the results of the interRAI-post acute care instrument (interRAI-PAC) with hospital discharge records. Factors associated with readmissions within 90 days following discharge were analysed using logistic regression analysis. RESULTS: The patients' mean age was 84.5 (SD 6.2) years, and 71% (n = 827) were women. The 90-day readmission rate was 29.5%. The risk factors associated with readmission in the univariate analysis were as follows: age, admission from home vs. acute care hospital, Alzheimer's disease, unsteady gait, fatigue, unstable conditions, Activities of Daily Living Hierarchy Scale (ADLH) score, Cognitive Performance Scale (CPS) score, body mass index (BMI), frailty index, bowel incontinence, hearing difficulties, and poor self-rated health. In the multivariable analysis, age of ≥90 years, ADLH ≥1, unsteady gait, BMI <25 or ≥30 kg/m 2 , and frailty remained as risk factors for readmission. Surgical operation during the treatment period was associated with a lower readmission risk. CONCLUSIONS AND IMPLICATIONS: InterRAI-PAC performed upon admission to geriatric hospitals revealed patient-related risk factors for readmission. Based on the identified risk factors, we recommend that the patient's functional ability, activities of daily living (ADL) needs, and individual factors underlying ADL disability, as well as nutritional and mobility problems should be carefully addressed and managed during hospitalization to diminish the risk for readmission.

Reasons for home care clients' unplanned Hospital admissions and their associations with patient characteristics.

BACKGROUND: Unplanned hospitalizations and emergency room visits occur frequently among home care clients The aim of this study was to identify typical discharge diagnoses and their associations with patient characteristics among a total of 6812 Finnish home care clients aged ≥63 years who were hospitalized within one year of their first home care assessment. METHODS: A register-based study based on Resident Assessment Instrument-Home Care (RAI-HC) assessments and nationwide hospital discharge records. The RAI-HC assessments were linked to the hospital discharge records of the participants' first unplanned hospitalization. Univariate and multivariable regression analyses were used to evaluate the association of RAI-HC determinants with discharge diagnoses. RESULTS: The most common reason for the first hospitalization was an infectious disease (21%; n = 1446). When hospitalizations were classified according to the main diagnosis, chronic skin ulcers, functional impairment and daily urinary incontinence were associated with hospitalization due to infectious diseases; impaired cognitive capacity, Alzheimer's disease or other dementia and polypharmacy (protective effect) were associated with hospitalizations due to dementia; age of ≥90 years, congestive heart failure, coronary artery disease and using ≥10 drugs with hospitalizations due to heart diseases; and moderate or strong pain with hospitalization due to musculoskeletal disorders. Previous falls, female sex and an earlier hip fracture were associated with injury-related hospitalizations. Feelings of loneliness increased the odds of hospitalization due to geriatric symptoms without a specific diagnosis. CONCLUSION: Patient characteristics and geriatric syndromes identified using RAI-HC predict the reasons for future hospitalizations among new home care clients.

Predictors for Unplanned Hospitalization of New Home Care Clients.

OBJECTIVES: To identify factors predicting unplanned hospitalization of new home care clients using the Resident Assessment Instrument for Home Care (RAI-HC). DESIGN: A register-based study based on RAI-HC assessments and nationwide hospital discharge records. SETTING: Municipal home care services in Finland. PARTICIPANTS: New Finnish home care clients aged 63 and older (N = 15,700). MEASUREMENTS: Information from home care clients' first RAI-HC assessment was connected to information regarding their first hospitalization over 1 year of follow-up. Multivariate regression analyses were used to evaluate the independent risk factors for hospitalization. RESULTS: Forty-three percent (n = 6,812) of participants were hospitalized at least once. The strongest independent risk factors were hospitalization during the year preceding the RAI-HC assessment (odds ratio (OR) = 2.01, 95% confidence interval (CI) = 1.87-2.16), aged 90 and older (OR = 1.69, 95% CI = 1.48-1.92), renal insufficiency (OR = 1.44, 95% CI = 1.22-1.69) and using 10 or more drugs (OR = 1.41, 95% CI = 1.26-1.58). Other independent risk factors were male sex, previous emergency department visits or other acute outpatient care use, daily urinary incontinence, fecal incontinence, history of falls, cognitive impairment, chronic skin ulcer, pain, unstable health status, housing-related problems, and poor self-rated health. Parkinson's disease, coronary artery disease, congestive heart failure, chronic obstructive pulmonary disease, and cancer were independent prognostic indicators. A body mass index of 24 kg/m2 or greater and the client's own belief that functional capacity could improve had a protective role. CONCLUSION: Assessing new home care clients using the RAI-HC reveals modifiable risk factors for unplanned hospitalization. Systematic assessment by a multidisciplinary team at the beginning of the service and targeting modifiable risk factors could reduce the risk of unplanned hospitalization.

Prognostic significance of serum cholesterol, lathosterol, and sitosterol in old age; a 17-year population study.

BACKGROUND. Low serum total cholesterol is frequently associated with worse survival in older people, but mechanisms of this association are poorly understood. AIMS. Characteristics of cholesterol metabolism were related to survival in a random 75 + population sample. METHODS. Serum cholesterol and lathosterol, and sitosterol were measured in random persons (n = 623) of birth cohorts (1904, 1909, and 1914) in 1990, and all persons were followed for 17 years. RESULTS. Total cholesterol declined in old age, and low cholesterol was associated with poor health and multi-morbidity. Cholesterol below 5.0 mmol/L was associated with accelerated all-cause mortality (age- and gender-adjusted hazard ratio (HR) 1.54; 95% CI 1.21-1.97; P < 0.001) and vascular mortality (HR 2.13 (1.42-3.07); P < 0.001). Lathosterol (indicating cholesterol synthesis) and sitosterol (indicating cholesterol absorption) also decreased with deteriorating health. Low lathosterol, sitosterol, and cholesterol predicted mortality additively and independently of each other. When all three sterols were high (> median) or low, the age- and gender-adjusted survival was 9.9 and 5.6 years (P < 0.001). CONCLUSION. Lower synthesis and absorption of cholesterol, and low serum cholesterol level are associated with deteriorating health and indicate impaired survival in old age.
