Prediction of Adverse Health Outcomes in Older People Using a Frailty Index Based on Routine Primary Care Data

BACKGROUND A general frailty indicator could guide general practitioners (GPs) in directing their care efforts to the patients at highest risk. We investigated if a Frailty Index (FI) based on the routine health care data of GPs can predict the risk of adverse health outcomes in community-dwelling older people. METHODS This was a retrospective cohort study with a 2-year follow-up period among all patients in an urban primary care center aged 60 and older: 1,679 patients (987 women [59%], median age, 73 years [interquartile range, 65-81]). For each patient, a baseline FI score was computed as the number of health deficits present divided by the total number of 36 deficits on the FI. Adverse health outcomes were defined as the first registered event of an emergency department (ED) or after-hours GP visit, nursing home admission, or death. RESULTS In total, 508 outcome events occurred within the sample population. Kaplan-Meier survival curves were constructed according to FI tertiles. The tertiles were able to discriminate between patients with low, intermediate, and high risk for adverse health outcomes (p value < .001). With adjustments for age, consultation gap, and sex, a one deficit increase in the FI score was associated with an increased hazard for adverse health outcomes (hazard ratio, 1.166; 95% confidence interval [CI], 1.129-1.210) and a moderate predictive ability for adverse health outcomes (c-statistic, 0.702; 95% CI, 0.680-0.724). CONCLUSIONS An FI based on International Classification of Primary Care (ICPC)-encoded routine health care data does predict the risk of adverse health outcomes in elderly population.

Screening for frailty in primary care: a systematic review of the psychometric properties of the frailty index in community-dwelling older people

BackgroundTo better accommodate for the complex care needs of frail, older people, general practitioners must be capable of easily identifying frailty in daily clinical practice, for example, by using the frailty index (FI). To explore whether the FI is a valid and adequate screening instrument for primary care, we conducted a systematic review of its psychometric properties.MethodsWe searched the Cochrane, PubMed and Embase databases and included original studies focusing on the criterion validity, construct validity and responsiveness of the FI when applied in community-dwelling older people. We evaluated the quality of the studies included using the Quality in Prognosis Studies (QUIPS) tool. This systematic review was conducted based on the PRISMA statement.ResultsOf the twenty studies identified, eighteen reported on FIs derived from research data, one reported upon an FI derived from an administrative database of home-care clients, and one reported upon an FI derived from routine primary care data. In general, the FI showed good criterion and construct validity but lacked studies on responsiveness. When compared with studies that used data gathered for research purposes, there are indications that the FI mean score and range might be different in datasets using routine primary care data; however, this finding needs further investigation.ConclusionsOur results suggest that the FI is a valid frailty screening instrument. However, further research using routine Electronic Medical Record data is necessary to investigate whether the psychometric properties of the FI are generalizable to a primary care setting and to facilitate its interpretation and implementation in daily clinical practice.Trial registrationPROSPERO systematic review register number: CRD42013003737.

Identifying frailty: do the Frailty Index and Groningen Frailty Indicator cover different clinical perspectives? a cross-sectional study

BackgroundEarly identification of frailty is important for proactive primary care. Currently, however, there is no consensus on which measure to use. Therefore, we examined whether a Frailty Index (FI), based on ICPC-coded primary care data, and the Groningen Frailty Indicator (GFI) questionnaire identify the same older people as frail.MethodsWe conducted a cross-sectional, observational study of 1,580 patients aged ≥ 60 years in a Dutch primary care center. Patients received a GFI questionnaire and were surveyed on their baseline characteristics. Frailty-screening software calculated their FI score. The GFI and FI scores were compared as continuous and dichotomised measures.ResultsFI data were available for 1549 patients (98%). 663 patients (42%) returned their GFI questionnaire. Complete GFI and FI scores were available for 638 patients (40.4%), mean age 73.4 years, 52.8% female. There was a positive correlation between the GFI and the FI (Pearson’s correlation coefficient 0.544). Using dichotomised scores, 84.3% of patients with a low FI score also had a low GFI score. In patients with a high FI score, 55.1% also had a high GFI score. A continuous FI score accurately predicted a dichotomised GFI score (AUC 0.78, 95% CI 0.74 to 0.82). Being widowed or divorced was an independent predictor of both a high GFI score in patients with a low FI score, and a high FI score in patients with a low GFI score.ConclusionsThe FI and the GFI moderately overlap in identifying frailty in community-dwelling older patients. To provide optimal proactive primary care, we suggest an initial FI screening in routine healthcare data, followed by a GFI questionnaire for patients with a high FI score or otherwise at high risk as the preferred two-step frailty screening process in primary care.

Factors associated with increasing functional decline in multimorbid independently living older people

OBJECTIVES With increasing age the levels of activities of daily living (ADL) deteriorate. In this study we aimed to investigate which demographic characteristics and disorders are associated with ADL disabilities in multi-morbid older people. STUDY DESIGN We performed a cross-sectional study with baseline patient data from a large Dutch trial in independently living multi-morbid older people combined with the reimbursed healthcare data for the same subjects. MAIN OUTCOME MEASURES The primary outcome of our study was the level of independence of activities of daily living (ADL) as assessed with the Modified Katz Activities of Daily Living (KATZ-15) scale. RESULTS In our study we were able to include 1187 persons (63.0% female) for whom both questionnaire data and reimbursed healthcare data was available. In total, 59% had a Katz-15 score of 1 or higher. The strongest associations with ADL disabilities in women were psychiatric disorders, with prevalence rate (PR) estimates of 1.37 (95% confidence interval (CI): 1.17-1.60) and transient ischaemic attacks and cerebrovasculair accidents in men, with PR estimates of 1.94 (95% CI: 1.41-2.66). Although univariate analysis seemed to also reveal associations with socio-demographic factors such as living together with a partner or the socio-economic status, these factors were not independently associated with ADL disabilities. CONCLUSIONS In this cross-sectional study we found that 71% of the multi-morbid female elderly had a sub-optimal level of activities of daily living, as assessed with the Katz-15 scale. The results of our study show that multiple disorders are associated with ADL disabilities in multi-morbid older men and women. We found socio-demographic characteristics not to be independently associated ADL disabilities.

Development of a Proactive Care Program (U‐CARE) to Preserve Physical Functioning of Frail Older People in Primary Care

PURPOSE Care for older patients in primary care is currently reactive, fragmented, and time consuming. An innovative structured and proactive primary care program (U-CARE) has been developed to preserve physical functioning and enhance quality of life of frail older people. This study describes in detail the development process of the U-CARE program to allow its replication. METHODS The framework of the Medical Research Council (MRC) for the development and evaluation of complex interventions was used as a theoretical guide for the design of the U-CARE program. An extended stepwise multimethod procedure was used to develop U-CARE. A team of researchers, general practitioners, registered practice nurses, experts, and an independent panel of older persons was involved in the development process to increase its feasibility in clinical practice. A systematic review of the literature and of relevant guidelines, combined with clinical practice experience and expert opinion, was used for the development of the intervention. FINDINGS Based on predefined potentially effective guiding components, the U-CARE program comprises three steps: a frailty assessment, a comprehensive geriatric assessment at home followed by a tailor-made care plan, and multiple follow-up visits. Evidence-based care plans were developed for 11 geriatric conditions. The feasibility in clinical practice was tested and approved by experienced registered practice nurses. CONCLUSIONS Using the MRC Framework, a detailed description of the development process of the innovative U-CARE program is provided, which is often missing in reports of complex intervention trials. Based on our feasibility-pilot study, the general practitioners and the registered practice nurses indicated that the U-CARE intervention is feasible in clinical practice. CLINICAL RELEVANCES The U-CARE program consists of promising components and has the potential to improve the care of older patients.

Treatment Fidelity of an Evidence-Based Nurse-Led Intervention in a Proactive Primary Care Program for Older People

BACKGROUND In a large randomized trial, Utrecht PROactive Frailty Intervention Trial (U-PROFIT), we evaluated the effectiveness of an integrated program on the preservation of daily functioning in older people in primary care that consisted of a frailty identification tool and a multicomponent nurse-led care program. Examination of treatment fidelity is critical to successful translation of evidence-based interventions into practice. AIMS To assess treatment delivery, dose and content of nursing care delivered within the nurse-led care program, and to explore if the delivery may have influenced the trial results. METHODS A mixed-methods study was conducted. Type and dose of nursing care were collected during the trial. Shortly after the trial, a focus group with nurses was conducted to explore reasons for the observed differences between the type and dose of nursing care delivered. RESULTS A total of 835 older persons were included in the nurse-led care program. The mean age was 75 years, 64% were female and 53.5% were living alone. The most frequent self-reported conditions were loneliness (60.8%) and cognitive problems (59.4%). One-third of the patients with a geriatric condition received an additional assessment (e.g., Mini-Mental State Examination), and the majority of these patients received at least one nurse intervention (>85%). Most nursing care was delivered to patients at risk of falling and to those with urinary incontinence. Patients with nutrition problems seldom received nursing interventions. The nurses explained that differences in type and dose were influenced by the preference of the patient, the type of geriatric problem, and the time required to apply a nurse intervention. LINKING EVIDENCE TO ACTION All intervention components were delivered; however, differences were observed in the type and dose of nursing care delivered across geriatric conditions. The findings better explain the treatment fidelity and suggest that there is room for improvement that may result in more beneficial patient outcomes.

Disability in the individual ADL, IADL, and mobility among older adults : A prospective cohort study

ObjectivesTo examine the risk of disability in 15 individual ADL, IADL, and mobility in older adults by age; and to assess the association of multimorbidity, gender, and education with disability.Design & SettingA prospective cohort study. The sample included 805 community-dwelling older people aged 60+ living in the Netherlands.MeasurementsDisability was assessed using the Katz-15 Index of Independence in Basic Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL) and one mobility item. Disability in any of these activities was defined as the inability to perform the activity without assistance. The risk of disability by age for each individual ADL, IADL, and for mobility was assessed using Generalized mixed models.ResultsDisability in activities as household tasks, traveling, shopping, and continence had the highest risk and increased rapidly with age. The risk traveling disability among people aged 65 with two comorbidities increase from 9% to 37% at age 85. Disability in using the telephone, managing medications, finances, transferring, and toileting, had a very low risk and hardly increased with age. Compared to those without chronic conditions, those with ≥ 3 chronic conditions had a 3 to 5 times higher risk of developing disability. Males had a higher risk of disability in managing medication (P=0.005), and preparing meals (P=0.019), whereas females had a higher risk of disability with traveling (P=0.001). No association between education and disability on the individual ADL, IADL, and mobility was observed.ConclusionsOlder adults were mostly disabled in physical related activities, whereas disability in more cognitive related activities was less often experienced. The impact of multimorbidity on disability in each activity was substantial, while education was not.
