- Background: Interpretation laboratory analyses are crucial when assessing the patient’s condition. Reference intervals from apparently healthy and disease-free individuals may cause problems when outcomes from elderly patients with chronic diseases and on medications are being interpreted. Elderly individuals are a heterogeneous group ranging from individuals managing their daily life independently to individuals with diseases and impairment, in need of nursing care around the clock, that is, frail; a term widely used although there is no consensus on the definition.Aims and Objectives: The aim of the study was to study the effect of classification of elderly into healthy, moderately healthy, and frail, based on activities of daily living (ADL) and Mini-Mental State Examination (MMSE) or frailty index (FI), on the interpretation of outcomes regarding: Albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, and gamma-glutamyltransferase (γ-GT) levels.Materials and Methods: Individuals ≥80 years (n=568) were classified either on ADL and MMSE or number of deficits, (FI).Results: Individuals classified as frail based on FI had lower mean levels for ALT, creatinine and γ-GT than individuals classified based on ADL and MMSE (P<0.05).Conclusion: The model to define health status to some extent affected laboratory analyte levels in ≥80 years old, classified as healthy, moderately healthy, and frail based on ADL and MMSE versus FI.

- Most adverse events in health care are related to medication management and they are almost always preventable. Increased knowledge of patient safety related to medication management in home health care is an urgent issue to provide safe care for all patients regardless of where the health care takes place. This study explored patient safety within medication management in municipal home health care. Vignettes were used as stimulus during qualitative interviews with registered nurses. Three main themes with related subthemes were identified as challenges to patient safety within medication management in home health care: (1) challenges to information transfer, (2) challenges related to delegation, and (3) challenges of advanced medical treatments in the home. The issue of transfer of information permeated our findings. Coordinating medications, delegating tasks, along with more advanced care require clear communication between care providers to be compatible with patient safety within medication management in home health care.

- Normative data for evaluating cognitive function in the oldest old, aged 85 years and above, are currently sparse. The normative values used in clinical practice are often derived from younger old persons, from small sample sizes or from broad age spans (e.g. amp;gt;75 years) resulting in a risk of misjudgment in assessments of cognitive decline. This longitudinal study presents normative values for the Trail Making Test A (TMT-A), the Symbol Digit Modalities Test (SDMT), the Victoria Stroop Test (VST) and the Parallel Serial Mental Operations (PaSMO) from cognitively intact Swedes aged 85 years and above. 207 participants, born in 1922, were tested at 85, 90 (n = 68) and 93 (n = 35) years of age with a cognitive screening test battery. The participants were originally recruited for participation in the Elderly in Linkoping Screening Assessment. Normative values are presented as mean values and standard deviations, with and without adjustment for education. There were no clinically important differences between genders, but education had a significant effect on test results for the 85-year-olds. Age effects emerged in analyses of those participants who completed the entire study and were evident for TMT-A, SDMT, VST1 and PaSMO. When comparisons can be made, our results are in accordance with previous data for TMT-A, SDMT and VST, and we present new normative values for PaSMO.

- Naming ability and verbal comprehension are cognitive functions that may be affected both by normal aging and by disease. Neuropsychological testing is crucial to evaluate changes in language ability and reliable normative data for all ages are needed. We present clinically useful test norms, together with subsample analysis of longitudinal effects of aging, for two robust and well-known tests that evaluate naming ability and verbal comprehension where the present norms for older adults (aged 85 and older) are sparse or missing. Participants (n = 338) from a Swedish population-based study, the Elderly in Linkoping Screening Assessment, were cognitively evaluated with a cognitive screening battery at the age of 85 years and followed to the age of 93 years. Normative data at age 85 years were calculated from a sample (n = 207) that was determined as cognitively healthy after application of rigorous exclusion criteria. Effects of normal aging were investigated by analyzing follow-up performance at age 90 and 93 years for the subsample of cognitively healthy that completed the entire study. The evaluated tests in this study are Swedish versions of the Boston Naming Test 30-item Odd Version (BNT-30) and a short form of the Token Test, Part V (TokV). Analyzes of effects of aging showed that performance decreased with age for BNT-30, but not for TokV. Higher education was associated with better performance in both tests and men performed better than women on the BNT-30. Results also showed naming ability to be more sensitive to aging than verbal comprehension.

- One characteristic histopathological event in Alzheimer disease (AD) is cerebral amyloid aggregation, which can be detected by biomarkers in cerebrospinal fluid (CSF) and on positron emission tomography (PET) scans. Prevalence estimates of amyloid pathology are important for health care planning and clinical trial design.To estimate the prevalence of amyloid abnormality in persons with normal cognition, subjective cognitive decline, mild cognitive impairment, or clinical AD dementia and to examine the potential implications of cutoff methods, biomarker modality (CSF or PET), age, sex, APOE genotype, educational level, geographical region, and dementia severity for these estimates.This cross-sectional, individual-participant pooled study included participants from 85 Amyloid Biomarker Study cohorts. Data collection was performed from January 1, 2013, to December 31, 2020. Participants had normal cognition, subjective cognitive decline, mild cognitive impairment, or clinical AD dementia. Normal cognition and subjective cognitive decline were defined by normal scores on cognitive tests, with the presence of cognitive complaints defining subjective cognitive decline. Mild cognitive impairment and clinical AD dementia were diagnosed according to published criteria.Alzheimer disease biomarkers detected on PET or in CSF.Amyloid measurements were dichotomized as normal or abnormal using cohort-provided cutoffs for CSF or PET or by visual reading for PET. Adjusted data-driven cutoffs for abnormal amyloid were calculated using gaussian mixture modeling. Prevalence of amyloid abnormality was estimated according to age, sex, cognitive status, biomarker modality, APOE carrier status, educational level, geographical location, and dementia severity using generalized estimating equations.Among the 19097 participants (mean [SD] age, 69.1 [9.8] years; 10148 women [53.1%]) included, 10139 (53.1%) underwent an amyloid PET scan and 8958 (46.9%) had an amyloid CSF measurement. Using cohort-provided cutoffs, amyloid abnormality prevalences were similar to 2015 estimates for individuals without dementia and were similar across PET- and CSF-based estimates (24%; 95% CI, 21%-28%) in participants with normal cognition, 27% (95% CI, 21%-33%) in participants with subjective cognitive decline, and 51% (95% CI, 46%-56%) in participants with mild cognitive impairment, whereas for clinical AD dementia the estimates were higher for PET than CSF (87% vs 79%; mean difference, 8%; 95% CI, 0%-16%; P=.04). Gaussian mixture modeling-based cutoffs for amyloid measures on PET scans were similar to cohort-provided cutoffs and were not adjusted. Adjusted CSF cutoffs resulted in a 10% higher amyloid abnormality prevalence than PET-based estimates in persons with normal cognition (mean difference, 9%; 95% CI, 3%-15%; P=.004), subjective cognitive decline (9%; 95% CI, 3%-15%; P=.005), and mild cognitive impairment (10%; 95% CI, 3%-17%; P=.004), whereas the estimates were comparable in persons with clinical AD dementia (mean difference, 4%; 95% CI, -2% to 9%; P=.18).This study found that CSF-based estimates using adjusted data-driven cutoffs were up to 10% higher than PET-based estimates in people without dementia, whereas the results were similar among people with dementia. This finding suggests that preclinical and prodromal AD may be more prevalent than previously estimated, which has important implications for clinical trial recruitment strategies and health care planning policies.

Tidskriftsartikel (refereegranskat)abstract
- Background The healthcare for older adults is insufficient in many countries, not designed to meet their needs and is often described as disorganized and reactive. Prediction of older persons at risk of admission to hospital may be one important way for the future healthcare system to act proactively when meeting increasing needs for care. Therefore, we wanted to develop and test a clinically useful model for predicting hospital admissions of older persons based on routine healthcare data. Methods We used the healthcare data on 40,728 persons, 75-109 years of age to predict hospital in-ward care in a prospective cohort. Multivariable logistic regression was used to identify significant factors predictive of unplanned hospital admission. Model fitting was accomplished using forward selection. The accuracy of the prediction model was expressed as area under the receiver operating characteristic (ROC) curve, AUC. Results The prediction model consisting of 38 variables exhibited a good discriminative accuracy for unplanned hospital admissions over the following 12 months (AUC 0.69 [95% confidence interval, CI 0.68-0.70]) and was validated on external datasets. Clinically relevant proportions of predicted cases of 40 or 45% resulted in sensitivities of 62 and 66%, respectively. The corresponding positive predicted values (PPV) was 31 and 29%, respectively. Conclusion A prediction model based on routine administrative healthcare data from older persons can be used to find patients at risk of admission to hospital. Identifying the risk population can enable proactive intervention for older patients with as-yet unknown needs for healthcare.

- Objectives To estimate the cost-effectiveness of a pragmatic trial of comprehensive geriatric assessment adapted to primary care, compared with care as usual. Design Within-trial cost-effectiveness study of a prospective controlled multicenter trial. Setting and Participants Nineteen primary care practices in Sweden. The original trial included 1304 individuals aged ≥75 years at high risk of hospitalization selected using a prediction model. From the original trial, 369 individuals participated in the cost-effectiveness analysis, 185 in the intervention group and 184 in the control group. Mean age was 83.9 years and 57% of the participants were men. Methods We obtained health care costs from administrative registries. Community costs and health-related quality of life data were obtained from a questionnaire sent to participants. Health-related quality of life was measured using EQ-5D-3L and quality-adjusted life years were calculated. We analyzed all outcomes according to intention to treat, and adjusted them to age, gender, and risk score (risk of hospitalization in the next 12 months). The primary outcome was the incremental cost-effectiveness ratio associated with the intervention at follow-up after 24 months. Results The difference in total cost (incremental cost) between intervention and control groups was USD −11,275 (95% CI −407 to −22,142). The incremental effect in quality-adjusted life years was −0.05 (95% CI −0.17 to 0.08). In the cost-effectiveness plane that illustrates the uncertainty of the analysis, 77.9 of the observations were within the south-east quadrant, implying lower cost and greater effect in the intervention group. Conclusions and Implications The results suggests that a primary care comprehensive geriatric assessment intervention delivered to older adults at high risk of hospitalization is cost-effective at follow-up after 24 months. The use of a prediction model to select participants and an intervention with a low cost is promising but requires further study.

- BackgroundThe healthcare system needs effective strategies to identify the most vulnerable group of older patients, assess their needs and plan their care proactively. To evaluate the effectiveness of comprehensive geriatric assessment (CGA) of older adults with a high risk of hospitalisation we conducted a prospective, pragmatic, matched-control multicentre trial at 19 primary care practices in Sweden.MethodsWe identified 1604 individuals aged 75years and older using a new, validated algorithm that calculates a risk score for hospitalisation from electronic medical records. After a nine-month run-in period for CGA in the intervention group, 74% of the available 646 participants had accepted and received CGA, and 662 participants remained in the control group. Participants at intervention practices were invited to CGA performed by a nurse together with a physician. The CGA was adapted to the primary care context. The participants thereafter received actions according to individual needs during a two-year follow-up period. Participants at control practices received care as usual. The primary outcome was hospital care days. Secondary outcomes were number of hospital care episodes, number of outpatient visits, health care costs and mortality. Outcomes were analysed according to intention to treat and adjusted for age, gender and risk score. We used generalised linear mixed models to compare the intervention group and control group regarding all outcomes.ResultsMean age was 83.2years, 51% of the 1308 participants were female. Relative risk reduction for hospital care days was -22% (-35% to -4%, p=0.02) during the two-year follow-up. Relative risk reduction for hospital care episodes was -17% (-30% to -2%, p=0.03). There were no significant differences in outpatient visits or mortality.Health care costs were significantly lower in the intervention group, adjusted mean difference was Euro - 4324 (Euro - 7962 to -686, p=0.02).Conclusions and relevanceOur findings indicate that CGA in primary care can reduce the need for hospital care days in a high-risk population of older adults. This could be of great importance in order to manage increasing prevalence of frailty and multimorbidity.Trial registrationclinicaltrials.gov Identifier: NCT03180606, first posted 08/06/2017.

Proactive Primary Care for Older Adults at High Risk of Hospital Admission
- 2022

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Demographic change is leading to a higher proportion of older adults in most parts of the world. A minority of older adults have poor health, but this group has high care needs due to frailty and/or multimorbidity. Guidelines for the management of frailty emphasise early detection of frailty and recommend comprehensive care approaches in primary care, but the evidence for these interventions is low. To provide effective and individualised care, the health system needs to identify these patients and develop proactive interventions to improve quality of life and avoid treatments that are of no benefit to the individual. The aim of this thesis was to study the effects of a proactive primary care working model in which vulnerable older adults were identified and received individually tailored care, using an adaptation of comprehensive geriatric assessment (CGA). Methods: A pragmatic controlled trial was conducted in 19 primary care practices in Sweden from 2017 to 2020. A predictive model, using electronic medical records to assess the risk of hospital admission, selected participants at high risk. Participants in the intervention practices were offered a comprehensive geriatric assessment in their primary care practice and subsequent follow-up by a team consisting of a nurse and the patient's doctor. A new CGA tool - PASTEL (Primary care ASsessment Tool for Elders) was used for assessment and care planning. The primary outcome for the intervention was hospital care days and secondary outcomes were hospital care episodes, mortality, outpatient visits, healthcare costs and cost-effectiveness. The outcomes were adjusted for age, sex and risk score and ana-lysed according to intention-to-treat. The predictive model was validated, and performance was assessed using the C-statistic. Focus group interviews were conducted to explore primary care nurses' and doctors' experiences with the new tool PASTEL. Results: 1304 older adults were included in the trial. The mean age was 82.2 years, 51% were female. During the follow-up period of 24 months, the relative risk reduction of hospital care days in the intervention group was - 22% (CI 95% = -35% to - 4%, p = 0.02) compared with usual care. There was no significant difference in mortality and outpatient visits. The reduction in healthcare costs was - € 4324 (- € 7962 to - € 686, p = 0.02). The intervention was cost-effective compared with usual care, mainly due to lower costs.The predictive model had an AUC of 0.69 (CI 0.68- 0.70). Primary care staff considered PASTEL valuable and feasible in the primary care context.In conclusion, the results of this thesis indicate that vulnerable older adults at risk of hospitalisation can be identified by a predictive model. Proactive intervention with a comprehensive geriatric assessment adapted to pri-mary care can reduce the need for hospital care. Future studies in similar contexts are needed to determine whether these results are generalisable.

- Objective: Comprehensive geriatric assessment (CGA) is recommended for the management of frailty. Little is known about professionals experiences of CGA; therefore we wanted to investigate the experiences of staff in primary care using a new CGA tool: the Primary care Assessment Tool for Elderly (PASTEL). Design: Focus group interviews. Manifest qualitative content analysis. Setting: Nine primary health care centres in Sweden that participated in a CGA intervention. These centres represent urban as well as rural areas. Subjects: Nine nurses, five GPs and one pharmacist were divided into three focus groups. Main outcome measures: Participants experiences of conducting CGA with PASTEL. Results: The analysis resulted in four main categories. A valuable tool for selected patients: The participants considered the assessment tool to be feasible and valuable. They stated that having enough time for the assessment interview was essential but views about the ideal patient for assessment were divided. Creating conditions for dialogue: The process of adapting the assessment to the individual and create conditions for dialogue was recognised as important. Managing in-depth conversations: In-depth conversations turned out to be an important component of the assessment. Patients were eager to share their stories, but talking about the future or the end of life was demanding. The winding road of actions and teamwork: PASTEL was regarded as a good preparation tool for care planning and a means of support for identifying appropriate actions to manage frailty but there were challenges to implement these actions and to obtain good teamwork. Conclusion: The participants reported that PASTEL, a tool for CGA, gave a holistic picture of the older person and was helpful in care planning.
