Multimorbidity and health-related quality of life in the older population: results from the German KORA-age study

Comparison of quality of life of older adults living in foster families versus nursing homes. Results from the KASA studies

OBJECTIVES

Professional foster families for dependent older adults could be an alternative to nursing homes. Engagement in the family life and close contact with a single reference person could enhance their quality of life (QOL). This study aimed to compare the Health-Related Quality of Life (HrQOL) and subjective QOL among older adults living in foster families versus those in nursing homes.

DESIGN

Cross-sectional analysis from twin studies conducted in foster families (the KASAF study) and nursing homes (the KASEHPAD study).

SETTING AND PARTICIPANTS

Older adults (aged 60 years or older) in French Caribbean Islands living in foster families or nursing homes.

MEASUREMENTS

HrQOL was measured using the EuroQol-five dimensions (EQ5D-3L) and QOL was assessed using a Visual Analog Scale (QOL-VAS). For older adults unable to complete these scales, proxy EQ-5D-3L assessments were conducted by paramedical staff or foster caregivers.

RESULTS

A total of 439 older adults, with 107 in foster families and 332 in nursing homes were included. Participants living in foster families were less often male, had less often hypertension, were more dependent or physical impaired and had lower score of cognition. In multivariate analyses, factors associated with low self-reported HRQoL (n = 240) were Mini Mental State Examination (MMSE) score (β: -0.011; p = 0.003) and Activities of Daily Living (ADL) score (β: 0.014; p < 0.001). A lower QOL-VAS score (n = 150) was associated with living in a nursing home compared to living in a foster family (β: -19.48 points; p < 0.001) and with the ADL score (2.94 points; p = 0.019). In older adults with major cognitive disorders, the only factor associated with low proxy EQ-5D proxy index score (n = 136) was dependency (β: 0.167; p < 0.001).

CONCLUSION

HrQOL was similar between older adults living in nursing homes and foster families. Additionally, older adults reported a better subjective quality of life when residing in foster families. These findings suggest that the foster family model may meet the social and environmental needs of dependent older adults for whom nursing homes are not suitable.

Bidirectional association between falls and multimorbidity in middle-aged and elderly Chinese adults: a national longitudinal study

This study explores the bidirectional association between multimorbidity and falls in Chinese middle-aged and elderly adults. Participants aged 45 and above from the China Health and Retirement Longitudinal Study were included. Binary logistic regression assessed the impact of chronic conditions on fall incidence (stage I), while multinomial logistic regression examined the relationship between baseline falls and multimorbidity (stage II). The fully adjusted odds ratios (ORs) for one, two, or three or more chronic conditions were 1.34, 1.65, and 2.02, respectively. Among participants without baseline falls, 28.61% developed two or more chronic conditions during follow-up, compared to 37.4% of those with a history of falls. Fully adjusted ORs for one, two, or three or more chronic conditions in those with a history of falls were 1.21, 1.38 and 1.70, respectively. The bidirectional relationship held in sensitivity and subgroup analyses. A bidirectional relationship exists between multimorbidity and falls in Chinese middle-aged and elderly adults. Strengthening chronic condition screening and treatment in primary healthcare may reduce falls risk, and prioritizing fall prevention and intervention in daily life is recommended.

Multimorbidity and health-related quality of life amongst Indigenous Australians: A longitudinal analysis

BACKGROUND

The burden of multimorbidity has been observed worldwide and it has significant consequences on health outcomes. In Australia, health-related quality of life (HRQoL) is comparatively low amongst Aboriginal and/or Torres Strait Islanders, yet no studies have examined the effect of multimorbidity on HRQoL within this at-risk population. This study seeks to fill that gap by employing a longitudinal research design.

METHODS

Longitudinal data were derived from three waves (9, 13, and 17) of the household, income and labour dynamics in Australia (HILDA) Survey. A total of 1007 person-year observations from 592 Aboriginal and/or Torres Strait Islander individuals aged 15 years and above were included. HRQoL was captured using the 36-item Short-Form Health Survey (SF-36), and multimorbidity was defined using self-reports of having been diagnosed with two or more chronic health conditions. Symmetric fixed-effects linear regression models were used to assess how intraindividual changes in multimorbidity were associated with intraindividual changes in HRQoL.

RESULTS

Approximately 21% of Indigenous Australians were classified as experiencing multimorbidity. Respondents had statistically significantly lower HRQoL on the SF-36 sub-scales, summary measures, and health-utility index in those observations in which they experienced multimorbidity. Among others, multimorbidity was associated with lower scores on the SF-36 physical-component scale (β =  - 6.527; Standard Error [SE] = 1.579), mental-component scale (β =  - 3.765; SE = 1.590) and short-form six-dimension utility index (β =  - 0.075; SE = 0.017).

CONCLUSION

This study demonstrates that having multiple chronic conditions is statistically significantly associated with lower HRQoL amongst Indigenous Australians. These findings suggest that comprehensive and culturally sensitive health strategies addressing the complex needs of individuals with multimorbidity should be implemented to improve the HRQoL of Indigenous Australians.

Multimorbidity and adverse longitudinal outcomes among patients attending chronic outpatient medical care in Bahir Dar, Northwest Ethiopia

Background

Multimorbidity is becoming more prevalent in low-and middle-income countries (LMICs). However, the evidence base on the burden and its longitudinal outcomes are limited. This study aimed to determine the longitudinal outcomes of patients with multimorbidity among a sample of individuals attending chronic outpatient non communicable diseases (NCDs) care in Bahir Dar, northwest Ethiopia.

Methods

A facility-based longitudinal study was conducted among 1,123 participants aged 40+ attending care for single NCD (n = 491) or multimorbidity (n = 633). Data were collected both at baseline and after 1 year through standardized interviews and record reviews. Data were analyzed using Stata V.16. Descriptive statistics and longitudinal panel data analyzes were run to describe independent variables and identify factors predicting outcomes. Statistical significance was considered at p-value <0.05.

Results

The magnitude of multimorbidity has increased from 54.8% at baseline to 56.8% at 1 year. Four percent (n = 44) of patients were diagnosed with one or more NCDs and those having multimorbidity at baseline were more likely than those without multimorbidity to develop new NCDs. In addition, 106 (9.4%) and 22 (2%) individuals, respectively were hospitalized and died during the follow up period. In this study, about one-third of the participants had higher quality of life (QoL), and those having higher high activation status were more likely to be in the higher versus the combined moderate and lower QoL [AOR1 = 2.35, 95%CI: (1.93, 2.87)] and in the combined higher and moderate versus lower level of QoL [AOR2 = 1.53, 95%CI: (1.25, 1.88)].

Conclusion

Developing new NCDs is a frequent occurrence and the prevalence of multimorbidity is high. Living with multimorbidity was associated with poor progress, hospitalization and mortality. Patients having a higher activation level were more likely than those with low activation to have better QoL. If health systems are to meet the needs of the people with chronic conditions and multimorbidity, it is essential to understand diseases trajectories and of impact of multimorbidity on QoL, and determinants and individual capacities, and to increase their activation levels for better health improve outcomes through education and activation.

Health State Utility Values of Type 2 Diabetes Mellitus and Related Complications: A Systematic Review and Meta-Analysis

OBJECTIVES

This study aims to synthesize health state utility values (HSUVs) of type 2 diabetes mellitus (T2DM) and its related complications published in the literature, conducting a meta-analysis of the data when possible.

METHODS

We conducted a systematic search in MEDLINE and School of Health and Related Research Health Utilities Database repository. Studies focused on T2DM and its complications reporting utility values elicited using direct and indirect methods were selected. We categorized the results according to the instrument to describe health and meta-analyzed them accordingly. Data included in the analysis were pooled in a fixed-effect model by the inverse of variance mean and random-effects DerSimonian-Laird method. Two approaches on sensitivity analysis were performed: leave-one-out method and including data of HSUVs obtained by foreign population value sets.

RESULTS

We identified 70 studies for the meta-analysis from a total of 467 studies. Sufficient data to pool T2DM HSUVs from EQ-5D instrument, hypoglycemia, and stroke were obtained. HSUVs varied from 0.7 to 0.92 in direct valuations, and the pooled mean of 3-level version of EQ-5D studies was 0.772 (95% confidence interval 0.763-0.78) and of 5-level version of EQ-5D 0.815 (95% confidence interval 0.808-0.823). HSUVs of complications varied from 0.739 to 0.843, or reductions of HSUVs between -0.014 and -0.094. In general, HSUVs obtained from 3-level version of EQ-5D and Health Utility Index 3 instruments were lower than those directly elicited. A considerable amount of heterogeneity was observed. Some complications remained unable to be pooled due to scarce of original articles.

CONCLUSIONS

T2DM and its complications have a considerable impact on health-related quality of life. 5-level version of EQ-5D estimates seems comparable with direct elicited HSUVs.

Exposure to anticholinergic and sedative medication is associated with impaired functioning in older people with vertigo, dizziness and balance disorders-Results from the longitudinal multicenter study MobilE-TRA

Introduction: Anticholinergic and sedative medication is prescribed for various conditions in older patients. While the general association between anticholinergic and sedative medication and impaired functioning is well established, its specific role in older individuals with vertigo, dizziness, and balance disorders (VDB) is still incompletely understood. The objective of this study was to investigate, whether an exposure to anticholinergic and sedative medication is associated with lower generic and lower vertigo-specific functioning in older patients with VDB. Methods: Data originates from the longitudinal multicenter study MobilE-TRA with two follow-ups, conducted from 2017 to 2019 in two German federal states. Exposure to anticholinergic and sedative medication was quantified using the drug burden index (DBI). Generic functioning was assessed by the Health Assessment Questionnaire Disability Index, appraising the amount of difficulties in performing activities of daily living (ADL). Vertigo-specific functioning was measured using the Vestibular Activities and Participation (VAP) questionnaire, assessing patient-reported functioning regarding activities of daily living that are difficult to perform because of their propensity to provoke VDB (Scale 1) as well as immediate consequences of VDB on activities and participation related to mobility (Scale 2). Longitudinal linear mixed models were applied to assess the association of exposure to anticholinergic and sedative medication at baseline and the level of generic and vertigo-specific functioning status over time. Results: An overall of 19 (7 from Bavaria) primary care physicians (mean age = 54 years, 29% female) recruited 158 (59% from Bavaria) patients with VDB (median age = 78 years, 70% female). Anticholinergic and sedative medication at baseline was present in 56 (35%) patients. An exposure to anticholinergic and sedative medication at baseline was significantly associated with lower generic functioning [Beta = 0.40, 95%-CI (0.18; 0.61)] and lower vertigo-specific functioning [VAP Scale 1: Beta = 2.47, 95%-CI (0.92; 4.02)], and VAP Scale 2: Beta = 3.74, 95%-CI [2.23; 5.24]). Conclusion: Our results highlight the importance of a close monitoring of anticholinergic and sedative medication use in older patients with VDB. When feasible, anticholinergic and sedative medication should be replaced by equivalent alternative therapies in order to potentially reduce the burden of VDB.

An analysis of socioeconomic factors on multiple chronic conditions and its economic burden: evidence from the National Health Service Survey in Yunnan Province, China

Background

The economic burden of multiple chronic conditions (MCCs) and its socio-economic influencing factors have widely raised public concerns. However, there are few large population-based studies on these problems in China. Our study aims at determining the economic burden of MCCs and associated factors specific to multimorbidity among middle-aged and older individuals.

Methods

As our study population, we extracted all 11,304 participants over 35 years old from the 2018 National Health Service Survey (NHSS) in Yunnan. Economic burden and socio-demographic characteristics were analyzed with descriptive statistics. Chi-square test and generalized estimating equations (GEE) regression models were used to identify influencing factors.

Results

The prevalence of chronic diseases was 35.93% in 11,304 participants and the prevalence of MCCs increased with age, was 10.12%. Residents who lived in rural areas were more likely to report MCCs than those who lived in urban areas (adjusted OR = 1.347, 97.5% CI: 1.116-1.626). Ethnic minority groups were less likely to report MCCs than those of Han (OR = 0.752, 97.5% CI: 0.601-0.942). Overweight or obese people were more likely to report MCCs than people with normal weight (OR = 1.317, 97.5% CI: 1.099-1.579). The per capita expenses of 2 weeks' illness, per capita hospitalization expenses, annual household income, annual household expenses, and annual household medical expenses of MCCs were ¥292.90 (±1427.80), ¥4804.22 (±11851.63), ¥51064.77 (±52158.76), ¥41933.50 (±39940.02) and ¥11724.94 (±11642.74), respectively. The per capita expenses of 2 weeks' illness, per capita hospitalization expenses, annual household income, annual household cost, and annual household medical expenses of hypertensive co-diabetic patients were more compared to those with other three comorbidity modes.

Conclusion

The prevalence of MCCs was relatively high among middle-aged and older individuals in Yunnan, China, which bought a heavy economic burden. This encourages policy makers and health providers to pay more attention to the behavioral/lifestyle factors, that contribute to multimorbidity to a great extent. Furthermore, health promotion and education in terms of MCCs need to be prioritized in Yunnan.

Oral nutritional interventions in frail older people who are malnourished or at risk of malnutrition: a systematic review

BACKGROUND

Malnutrition worsens the health of frail older adults. Current treatments for malnutrition may include prescribed oral nutritional supplements, which are multinutrient products containing macronutrients and micronutrients.

OBJECTIVE

To assess the effectiveness and cost-effectiveness of oral nutritional supplements (with or without other dietary interventions) in frail older people who are malnourished or at risk of malnutrition.

DATA SOURCES

MEDLINE, EMBASE, Cochrane Library, Scopus, CINAHL (Cumulative Index to Nursing and Allied Health Literature) and grey literature were searched from inception to 13 September 2021.

REVIEW METHODS

A systematic review and meta-analysis was conducted to evaluate the effectiveness and cost-effectiveness of oral nutritional supplements in frail older people (aged ≥ 65 years) who are malnourished or at risk of malnutrition (defined as undernutrition as per National Institute for Health and Care Excellence guidelines). Meta-analysis and network meta-analysis were undertaken, where feasible, along with a narrative synthesis. A cost-effectiveness review was reported narratively. A de novo model was developed using effectiveness evidence identified in the systematic review to estimate the cost-effectiveness of oral nutritional supplements.

RESULTS

Eleven studies (n = 822 participants) were included in the effectiveness review, six of which were fully or partly funded by industry. Meta-analyses suggested positive effects of oral nutritional supplements compared with standard care for energy intake (kcal) (standardised mean difference 1.02, 95% confidence interval 0.15 to 1.88; very low quality evidence) and poor mobility (mean difference 0.03, p < 0.00001, 95% confidence interval 0.02 to 0.04; very low quality evidence) but no evidence of an effect for body weight (mean difference 1.31, 95% confidence interval -0.05 to 2.66; very low quality evidence) and body mass index (mean difference 0.54, 95% confidence interval -0.03 to 1.11; very low quality evidence). Pooled results for other outcomes were statistically non-significant. There was mixed narrative evidence regarding the effect of oral nutritional supplements on quality of life. Network meta-analysis could be conducted only for body weight and grip strength; there was evidence of an effect for oral nutritional supplements compared with standard care for body weight only. Study quality was mixed; the randomisation method was typically poorly reported. One economic evaluation, in a care home setting, was included. This was a well-conducted study showing that oral nutritional supplements could be cost-effective. Cost-effectiveness analysis suggested that oral nutritional supplements may only be cost-effective for people with lower body mass index (< 21 kg/m2) using cheaper oral nutritional supplements products that require minimal staff time to administer.

LIMITATIONS

The review scope was narrow in focus as few primary studies used frailty measures (or our proxy criteria). This resulted in only 11 included studies. The small evidence base and varied quality of evidence meant that it was not possible to determine accurate estimates of the effectiveness or cost-effectiveness of oral nutritional supplements. Furthermore, only English-language publications were considered.

CONCLUSIONS

Overall, the review found little evidence of oral nutritional supplements having significant effects on reducing malnutrition or its adverse outcomes in frail older adults.

FUTURE WORK

Future research should focus on independent, high-quality, adequately powered studies to investigate oral nutritional supplements alongside other nutritional interventions, with longer-term follow-up and detailed analysis of determinants, intervention components and cost-effectiveness.

Multimorbidity and health-related quality of life among patients attending chronic outpatient medical care in Bahir Dar, Northwest Ethiopia: The application of partial proportional odds model

BACKGROUND

Multimorbidity, the presence of two or more chronic non-communicable diseases (NCDs) in a given person affects all aspects of people's lives. Poor quality of life (QoL) is one of the major consequences of living with multimorbidity. Although healthcare should support multimorbid individuals to achieve a better quality of life, little is known about the effect of multimorbidity on the QoL of patients living with chronic conditions. This study aimed to determine the influence of multimorbidity on QoL among clients attending chronic outpatient medical care in Bahir Dar, Northwest Ethiopia.

METHODOLOGY

A multi-centered facility-based study was conducted among 1440 participants aged 40+ years. Two complementary methods were employed to collect sociodemographic and disease related data. We used the short form (SF-12 V2) instrument to measure quality of life (QoL). The data were analyzed by STATA V.16, and a multivariate partial proportional odds model was fitted to identify covariates associated with quality of life. Statistical significance was considered at p-value <0.05.

PRINCIPAL FINDINGS

Multimorbidity was identified in 54.8% (95% CI = 52.2%-57.4%) of the sample. A significant proportion (33.5%) of the study participants had poor QoL and a quarter (25.8%) of them had moderate QoL. Advanced age, obesity and living with multimorbidity were the factors associated with poor QoL. Conversely, perceived social support and satisfaction with care were the variables positively associated with better QoL.

CONCLUSION

The magnitude of multimorbidity in this study was high and individuals living with multimorbidity had a relatively poorer QoL than those without multimorbidity. Care of people with chronic multiple conditions has to be oriented to the realities of multimorbidity burden and its implication on QoL. It is also imperative to replicate the methods we employed to measure and analyze QoL data in this study for facilitating comparison and further development of the approaches.

Social Network and Participation in Elderly Primary Care Patients in Germany and Associations with Depressive Symptoms-A Cross-Sectional Analysis from the AgeWell.de Study

This study aims to describe social network and social participation and to assess associations with depressive symptoms in older persons with increased risk for dementia in Germany. We conducted a cross-sectional observational study in primary care patients (aged 60−77) as part of a multicenter cluster-randomized controlled trial (AgeWell.de). We present descriptive and multivariate analyses for social networks (Lubben Social Network Scale and subscales) and social participation (item list of social activities) and analyze associations of these variables with depressive symptoms (Geriatric Depression Scale). Of 1030 included patients, 17.2% were at risk for social isolation (Lubben Social Network Scale < 12). Looking at the subscales, a reduced non-family network was found almost twice as often as a reduced family network. Patients with depressive symptoms had significantly smaller social networks than patients without depression (p < 0.001). They rather engaged in social activities of low involvement level or no weekly social activity at all (p < 0.001). The study shows associations of depressive symptoms with a decreased social network and less social participation in elderly participants. Sufficient non-family contacts and weekly social activities seem to play an important role in mental health and should be encouraged in elderly primary care patients.

Morbid obesity, multiple long-term conditions, and health-related quality of life among Australian adults: Estimates from three waves of a longitudinal household survey

This study aims to investigate the impact of morbid obesity and multiple long-term conditions (MLTCs) on health-related quality of life (HRQoL). Data for this study were sourced from three waves (waves 9, 13 and 17) of the Household, Income and Labour Dynamics in Australia (HILDA) survey. The paper analyses 37,887 person-year observations from 19,387 individuals during the period 2009-2017. The longitudinal random-effects Tobit model was fitted to examine the association between morbid obesity, MLTCs and HRQoL. This study found that morbid obesity and MLTCs were both negatively associated with HRQoL as measured through physical component summary (PCS), mental component summary (MCS), and the short-form six-dimension utility index (SF-6D) of the 36-item Short-Form Health Survey (SF-36). Morbidly obese scored lower points on the PCS (β = -5.05, 95% CI: -5.73, -4.37), MCS (β = -1.03, 95% CI: -1.84, -0.23), and in the SF-6D utility index (β = -0.045, 95% CI: -0.054, -0.036) compared to their healthy weight counterparts. Similar findings were observed for individuals with MLTCs, with lower scores for the PCS (β = -4.79, 95% CI: -5.20, -4.38), MCS (β = -4.95, 95% CI: -5.43, -4.48), and SF-6D utility (β = -0.071, 95% CI: -0.076, -0.066). Additionally, multiplicative interaction between morbid obesity and MLTCs was observed to modestly exacerbated the negative effect of morbid obesity on PCS scores (β = -1.69, 95% CI: -2.74, -0.64). The interaction effect, on the other hand, significantly lessen the unfavourable effect of morbid obesity on the MCS score (β = 1.34, 95% CI: 0.10, 2.58). The findings of this study will be useful for future cost-effectiveness analyses and measuring the burden of diseases since it provides information on the disutility associated with morbid obesity and MLTCs.

Identifying multimorbidity clusters among Brazilian older adults using network analysis: Findings and perspectives

In aging populations, multimorbidity (MM) is a significant challenge for health systems, however there are scarce evidence available in Low- and Middle-Income Countries, particularly in Brazil. A national cross-sectional study was conducted with 11,177 Brazilian older adults to evaluate the occurrence of MM and related clusters in Brazilians aged ≥ 60 years old. MM was assessed by a list of 16 physical and mental morbidities and it was defined considering ≥ 2 morbidities. The frequencies of MM and its associated factors were analyzed. After this initial approach, a network analysis was performed to verify the occurrence of clusters of MM and the network of interactions between coexisting morbidities. The occurrence of MM was 58.6% (95% confidence interval [CI]: 57.0–60.2). Hypertension (50.6%) was the most frequent morbidity and it was present all combinations of morbidities. Network analysis has demonstrated 4 MM clusters: 1) cardiometabolic; 2) respiratory + cancer; 3) musculoskeletal; and 4) a mixed mental illness + other diseases. Depression was the most central morbidity in the model according to nodes’ centrality measures (strength, closeness, and betweenness) followed by heart disease, and low back pain. Similarity in male and female networks was observed with a conformation of four clusters of MM and cancer as an isolated morbidity. The prevalence of MM in the older Brazilians was high, especially in female sex and persons living in the South region of Brazil. Use of network analysis could be an important tool for identifying MM clusters and address the appropriate health care, research, and medical education for older adults in Brazil.

Study protocol for an epidemiological study 'Multimorbidity - identifying the most burdensome patterns, risk factors and potentials to reduce future burden (MOLTO)' based on the Finnish health examination surveys and the ongoing register-based follow-up

INTRODUCTION

Multimorbidity, defined as the co-occurrence of two or more long-term medical conditions, is an increasing public health concern worldwide causing enormous burden to individuals, healthcare systems and societies. The most effective way of decreasing the burden caused by multimorbidity is to find tools for its successful prevention but gaps in research evidence limit capacities to develop prevention strategies. The aim of the MOLTO study (Multimorbidity - identifying the most burdensome patterns, risk factors and potentials to reduce future burden) is to provide novel evidence required for cost-effective prevention of multimorbidity by defining the multimorbidity patterns causing the greatest burden at the population level, by examining their risk and protective factors and by estimating the potentials to reduce the future burden.

METHODS AND ANALYSIS

The MOLTO study is based on the data from the Finnish population-based cross-sectional (FINRISK 2002-2012, FinHealth 2017 the Migrant Health and Well-being Study 2010-2012) and longitudinal (Health 2000/2011) health examination surveys with individual-level link to administrative health registers, allowing register-based follow-up for the study participants. Both cross-sectional and longitudinal study designs will be used. Multimorbidity patterns will be defined using latent class analysis. The burden caused by multimorbidity as well as risk and protective factors for multimorbidity will be analysed by survival analysis methods such as Cox proportional hazards and Poisson regression models.

ETHICS AND DISSEMINATION

The survey data have been collected following the legislation at the time of the survey. The ethics committee of the Hospital District of Helsinki and Uusimaa has approved the data collection and register linkages for each survey. The results will be published as peer-reviewed scientific publications.

Referral trajectories in patients with vertigo, dizziness and balance disorders and their impact on health-related quality of life and functioning: results from the longitudinal multicenter study MobilE-TRA

Background

Due to reported barriers in the management of patients with vertigo, dizziness and balance problems (VDB), referral trajectories starting from primary care might be determined by other factors than medical necessity. The objective of this paper was to examine the impact of disease-related and other determinants on referral trajectories of older patients with VDB and to investigate, how these trajectories affect the patients’ functioning and health-related quality of life (HRQoL).

Methods

Data originate from the longitudinal multicenter study MobilE-TRA, conducted in two German federal states. Referrals to neurologists or ear-nose-throat (ENT) specialists were considered. Referral patterns were visualized using a state sequence analysis. Predictors of referral trajectories were examined using a multinomial logistic regression model. Linear mixed models were calculated to assess the impact of referral patterns on the patients’ HRQoL and functioning.

Results

We identified three patterns of referral trajectories: primary care physician (PCP) only, PCP and neurologist, and PCP and ENT. Chances of referral to a neurologist were higher for patients with a neurological comorbidity (OR = 3.22, 95%-CI [1.003; 10.327]) and lower for patients from Saxony (OR = 0.08, 95%-CI [0.013; 0.419]). Patients with a PCP and neurologist referral pattern had a lower HRQoL and lower functioning at baseline assessment. Patients with unspecific diagnoses also had lower functioning.

Conclusion

Referral trajectories were determined by present comorbidities and the regional healthcare characteristics. Referral trajectories affected patients’ HRQoL. Unspecific VDB diagnoses seem to increase the risk of ineffective management and consequently impaired functioning.

Trajectory of Quality of Life Before and After Entering a Nursing Home: A Longitudinal Study

OBJECTIVES

The objective of this longitudinal study was to compare the trajectory of subjective quality of life in 2 groups of older adults: those who entered a nursing home and those who remained living in the community with similar clinical conditions.

METHOD

PAQUID is a prospective population-based study. It included, at baseline, 3777 community-dwelling participants aged 65 years and over. Participants were followed-up for up to 27 years. Among people living at home at baseline, 2 groups were compared: participants who entered a nursing home over a 20-year follow-up (n = 528) and those who remained community dwellers (n = 2273). We used latent process mixed models to estimate the relationship between mean trajectory of subjective quality of life and admission into a nursing home. We computed univariate and multivariate models taking into account potential confounders (age, gender, education, income, comorbidities, dementia, disability and depression).

RESULTS

Nursing home placement was significantly associated with a drop in quality of life between the last visit before and after institutionalization. Nevertheless, we found no difference in quality of life trajectory after this initial drop.

CONCLUSION

Older adults exhibit an acute drop in quality of life after nursing home admission, probably reflecting the associated psychological distress. Even though their quality of life does not go back to pre-admission levels, the residents do not show a steeper decline when compared to the "natural" evolution of quality of life in older adults living in the community, which suggests a relative adaptation to their new living conditions.

Caminho na rede formal de cuidado em saúde de pacientes pós-alta hospitalar segundo multimorbidade

Introdução: A gestão de informações associadas à multimorbidade na atenção hospitalar é relevante para o planejamento de estratégias de prevenção de agravos à saúde em pacientes de maior risco, a fim de oportunizar a organização de sistemas de saúde de modo eficiente. Objetivo: O presente trabalho objetivoudelinear o caminho formal percorrido por pacientes com e sem multimorbidade, considerando o uso da rede pública de saúde após a internação hospitalar. Materiais e métodos: Realizou-se um estudo quantitativo, transversal, descritivo, utilizando dados primários de 445 pacientes internados em um hospital universitário, no ano de 2018. Os dados foram coletados através de análise do prontuário médico e entrevista telefônica. Os resultados foram analisados por meio de frequência absoluta e relativa. Resultados: Desenvolveu-se um fluxograma, representando os pontos da rede de saúde utilizados pelo paciente após a alta hospitalar, segundo multimorbidade. Verificou-se uma alta prevalência de encaminhamento (com multimorbidade (CM) 93,52%; sem multimorbidade (SM) 97,71%) e comparecimento na atenção secundária à saúde (CM 86,15%; SM 89,63%), um baixo encaminhamento (CM 42,45%; SM 36,27%) e comparecimento na atenção primária à saúde (CM 61,29%; SM 64,81%), e considerando os 3 níveis de atenção juntos, houve um baixo comparecimento (CM 17,98%; SM 21,89%) para ambos os grupos investigados.

Conclusões: Sinaliza-se a importância de maior incentivo ao acompanhamento de pacientes com multimorbidade na rede primária de saúde, especialmente no período de pós-alta hospitalar, e a necessidade de fortalecimento da Rede de Atenção à Saúde.

Impact of elevated BMI and types of comorbid conditions on health-related quality of life in a nationally representative US sample

OBJECTIVE

Elevated BMI is associated with multiple chronic conditions including diabetes and CVD. Patients with overweight or obesity may also suffer from comorbidities not directly related to the pathophysiology of elevated BMI. The current study sought to determine the impact of BMI and different types of chronic conditions on health-related quality of life (HRQoL) outcomes.

DESIGN

Six weight categories by BMI were identified: underweight, normal weight, overweight, Class-I obesity, Class-II obesity and Class-III obesity. Twenty chronic conditions were considered and categorised as elevated BMI-related (concordant) or -unrelated (discordant) conditions. HRQoL outcomes were measured using Short Form-6 Dimensions (SF-6D). Multivariable regression models were performed to examine the impact of type, number of comorbid conditions and BMI categories on SF-6D scores.

SETTING

Medical Expenditure Panel Survey (2013-2015).

PARTICIPANTS

Nationally representative sample of US population; 18 years or older (n 58 960).

RESULTS

Of the sample, 1·7 %, 32·9 %, 34·0 % and 31·4 % were classified as underweight, normal weight, overweight and obese, respectively. The SF-6D scores were significantly decreased across all obesity classes, with the largest reduction in Class-III obesity (0·033; P < 0·001). Additionally, individuals with obesity having one or more concordant or discordant comorbidities further reduced SF-6D scores between 0·031 and 0·148 (P-values < 0·001) or between 0·080 and 0·212 (P-values < 0·001), respectively.

CONCLUSIONS

Individuals with obesity had a significant reduction in HRQoL outcomes compared to those with normal BMI. Importantly, discordant comorbidity resulted in greater reduction in HRQoL outcomes compared to concordant comorbidity in subjects with elevated BMI.

The impact of multimorbidity patterns on health-related quality of life in the general population: results of the Belgian Health Interview Survey

BACKGROUND

Chronic diseases and multimorbidity are a major cause of disease burden-for patients, caregivers, and society. Little is known however about potential interaction effects between specific disease combinations. Besides an additive effect, the presence of multiple conditions could also act synergistically or antagonistically regarding the impact on patients' health-related quality of life (HRQoL). The aim was to estimate the impact of coexisting chronic diseases on HRQoL of the adult general Belgian population.

METHODS

The Belgian Health Interview Survey 2018 provided data on self-reported chronic conditions and HRQoL (EQ-5D-5L) for a nationally representative sample. Linear mixed models were used to analyze two-way and three-way interactions of disease combinations on HRQoL.

RESULTS

Multimorbidity had a prevalence of 46.7% (≥ 2 conditions) and 29.7% (≥ 3 conditions). HRQoL decreased considerably with the presence of multiple chronic diseases. 14 out of 41 dyad combinations and 5 out of 13 triad combinations showed significant interactions, with a dominant presence of negative/synergistic effects. Positive/antagonistic effects were found in more subjective chronic diseases such as depression and chronic fatigue. Conditions appearing the most frequently in significant disease pair interactions were dorsopathies, respiratory diseases, and arthropathies.

CONCLUSIONS

Diverse multimorbidity patterns, both dyads and triads, were synergistically or antagonistically associated with lower HRQoL. Tackling the burden of multimorbidity is needed, especially because most disease combinations affect each other synergistically, resulting in a greater reduction in HRQoL. Further knowledge about those multimorbidity patterns with a greater impact on HRQoL is needed to better understand disease burden beyond mortality and morbidity data.

The impact of comorbidities on health-related quality of life of people with osteoarthritis over ten years

OBJECTIVE

To investigate the impact of total number and patterns of comorbidities on health-related quality of life (HRQoL) and identify the most prevalent and influential comorbidity patterns in people with osteoarthritis (OA) over ten years.

METHODS

Participants from the Tasmanian Older Adult Cohort aged 50-80 years, with self-reported OA and data on comorbidities and HRQoL were included. Participants were interviewed at baseline (n = 398), 2.5-years (n = 304), 5-years (n = 269) and 10-years (n = 191). Data on the self-reported presence of 10 chronic comorbidities were collected at baseline. HRQoL was assessed using the Assessment of Quality of Life-4-Dimensions. The long-term impacts of the number and of the nine most prevalent combinations of cardiovascular (CVD), non-OA musculoskeletal (Ms), metabolic, and respiratory comorbidities on HRQoL over ten years were analysed using linear mixed regressions.

RESULTS

Compared with comorbidity-free OA participants, the health state utility (HSU) of those with 2 or ≥ 3 comorbidities was respectively -0.07 and -0.13 units lower over ten years, largely driven by reduced scores for independent living, social relationships and psychological wellness. Comorbidity patterns including 'CVD+Ms' were most influential, and associated with up to 0.13 units lower HSU, mostly through negative impacts on independent living (up to -0.12), psychological wellness (up to -0.08) and social relationship (up to -0.06).

CONCLUSION

Having more comorbidities negatively impacted OA patients' long-term HRQoL. OA patients with CVD and non-OA musculoskeletal conditions had the largest HSU impairment, therefore optimal management and prevention of these conditions may yield improvements in OA patients' HRQoL.

Utility Decrements Associated With Diabetes and Related Complications: Estimates From a Population-Based Study in Germany

OBJECTIVES

Health utility decrement estimates for diabetes and complications are needed for parametrization of simulation models that aim to assess the cost-utility of diabetes prevention and care strategies. This study estimates health utility decrements associated with diabetes and cardiovascular and microvascular complications from a population-based German study.

METHODS

Data were obtained from the population based cross-sectional KORA (Cooperative Health Research in the Augsburg Region) health questionnaire 2016 and comprised n = 1072 individuals with type 2 diabetes and n = 7879 individuals without diabetes. Health utility was assessed through the EQ-5D-5L. We used linear regression models with interaction terms between type 2 diabetes and different cardiovascular and microvascular complications while adjusting for demographic and socio-economic factors and other comorbidities.

RESULTS

Type 2 diabetes (β = -0.028, standard error [SE] = 0.014), stroke (β = -0.070, SE = 0.010), cardiac arrhythmia (β = -0.031, SE = 0.006), heart failure (β = -0.073, SE = 0.009), coronary heart disease (β = -0.028, SE = 0.010), myocardial infarction (β = -0.020, SE = 0.011, estimates of main effect), and neuropathy (β = -0.067, SE = 0.020), diabetic foot (β = -0.042, SE = 0.030), nephropathy (β = -0.032, SE = 0.025), and blindness (β = -0.094, SE = 0.056, estimates of interaction terms) were negatively associated with health utility. The interaction term for diabetes x stroke (β = -0.052, SE = 0.021) showed that the utility decrement for stroke is significantly larger in people with type 2 diabetes than in people without diabetes.

CONCLUSIONS

Diabetes, cardiovascular, and microvascular conditions are associated with significant health utility decrements. Utility decrements for some conditions differ between people with and without type 2 diabetes. These results are of high relevance for the parametrization of decision analytic simulation models and applied health economic evaluations in the field of prevention and management of type 2 diabetes in Germany.

The association between clusters of chronic conditions and psychological well-being in younger and older people-A cross-sectional, population-based study from the Lolland-Falster Health Study, Denmark

Aim:

To investigate the association between clusters of conditions and psychological well-being across age groups.

Method:

This cross-sectional study used data collected in the Danish population-based Lolland-Falster Health Study. We included adults over the age of 18 years. Self-reported chronic conditions were divided into 10 groups of conditions. The primary outcome was psychological well-being (the WHO-5 Well-Being Index). Factor analysis constructed the clusters of conditions, and regression analysis investigated the association between clusters and psychological well-being.

Results:

Of 10,781 participants, 31.4% were between 18 and 49 years, 35.7% were between 50 and 64 years and 32.9% were above ≥65 years. 35.2% had conditions represented in 1 and 32.9% in at least 2 of 10 condition groups. Across age groups, living with one or more chronic conditions was associated with poorer psychological well-being. Two chronic condition patterns were identified; one comprised cardiovascular, endocrine, kidney, musculoskeletal and cancer conditions, the second mental, lung, neurological, gastrointestinal and sensory conditions. Both patterns were associated with poorer psychological well-being (Pattern 1: −4.5 (95% CI: −5.3 to −3.7), Pattern 2: −9.1 (95% CI −13.8 to −8.2). For pattern 2, participants ≥65 years had poorer psychological well-being compared to younger (−12.6 (95% CI −14.2 to −11.0) vs −6.6 (95% CI: −7.8 to −5.4) for 18–49 years and −8.7 (95% CI: −10.1 to −7.3) for 50–64 years, interaction: p ≤ 0.001)

Conclusion:

Living with one or more chronic conditions is associated with poorer psychological well-being. Findings point toward a greater focus on supporting psychological well-being in older adults with both mental and somatic conditions.

The patient at the centre: evidence from 17 European integrated care programmes for persons with complex needs

BACKGROUND

As the prevalence of multi-morbidity increases in ageing societies, health and social care systems face the challenge of providing adequate care to persons with complex needs. Approaches that integrate care across sectors and disciplines have been increasingly developed and implemented in European countries in order to tackle this challenge. The aim of the article is to identify success factors and crucial elements in the process of integrated care delivery for persons with complex needs as seen from the practical perspective of the involved stakeholders (patients, professionals, informal caregivers, managers, initiators, payers).

METHODS

Seventeen integrated care programmes for persons with complex needs in 8 European countries were investigated using a qualitative approach, namely thick description, based on semi-structured interviews and document analysis. In total, 233 face-to-face interviews were conducted with stakeholders of the programmes between March and September 2016. Meta-analysis of the individual thick description reports was performed with a focus on the process of care delivery.

RESULTS

Four categories that emerged from the overarching analysis are discussed in the article: (1) a holistic view of the patient, considering both mental health and the social situation in addition to physical health, (2) continuity of care in the form of single contact points, alignment of services and good relationships between patients and professionals, (3) relationships between professionals built on trust and facilitated by continuous communication, and (4) patient involvement in goal-setting and decision-making, allowing patients to adapt to reorganised service delivery.

CONCLUSIONS

We were able to identify several key aspects for a well-functioning integrated care process for complex patients and how these are put into actual practice. The article sets itself apart from the existing literature by specifically focussing on the growing share of the population with complex care needs and by providing an analysis of actual processes and interpersonal relationships that shape integrated care in practice, incorporating evidence from a variety of programmes in several countries.

Diabetes multimorbidity combinations and disability in the Mexican Health and Aging Study, 2012-2015

PURPOSE

The aim of this study was to investigate the relationship between specific combinations of chronic conditions and disability in Mexican older adults with diabetes.

METHODS

This was a prospective cohort study of Mexican adults (n = 2558) with diabetes and aged 51 or older that used data from the 2012 and 2015 waves of the Mexican Health and Aging Study. The main outcome was an index that measured ability to perform activities of daily living and instrumental activities of daily living. The main independent variables were diabetes multimorbidity combinations, defined as diabetes and at least one other chronic condition. The authors calculated the prevalence of each multimorbidity combination present in the sample in 2012 and used negative binomial regression models to estimate the association of the most prevalent of these combinations with disability incidence in 2015.

RESULTS

The three most prevalent combinations were: 1) diabetes-hypertension (n = 637, 31.9%) 2) diabetes-hypertension-depression (n = 388, 19.4%) and 3) diabetes-depression (n = 211, 10.6%). In fully adjusted models comparing participants with specific multimorbidity combinations to participants with diabetes alone, the combinations that had an increased association with disability were diabetes-hypertension-depression, diabetes-depression and diabetes-hypertension-arthritis-depression. In nested models, the addition of arthritis to combinations including depression increased this association.

CONCLUSIONS

Consistent with prior studies, multimorbidity combinations including depression were associated with increased risk of disability. However, the effect size of this relationship was lower than what had been previously been reported internationally. This highlights the need for globally oriented multimorbidity research.

The reliability, validity and factorial structure of the Swahili version of the 7-item generalized anxiety disorder scale (GAD-7) among adults living with HIV from Kilifi, Kenya

BACKGROUND

Generalized Anxiety Disorder (GAD) is under-investigated in people living with HIV/AIDS from sub-Saharan Africa. In part, this is due to paucity of culturally appropriate measures for GAD which are psychometrically robust. This study aimed to evaluate the reliability, factorial structure, and validity of Swahili version of the 7-item GAD questionnaire (GAD-7) among adults living with HIV.

STUDY DESIGN

Descriptive cross-sectional study.

METHODS

450 adults receiving comprehensive care from an HIV specialized clinic in Kilifi County, coastal Kenya, were consecutively recruited. Swahili versions of GAD-7, Patient Health Questionnaire (PHQ-9) and a 12-item HIV stigma scale were administered alongside measures of psychosocial and health-related characteristics. Internal consistency, test-retest reliability, factorial structure, convergent validity, and discriminant validity of Swahili GAD-7 were examined using Cronbach's alpha (α), intra-class correlation coefficient (ICC), Confirmatory Factor Analysis (CFA), Pearson's correlation, and analysis of covariance (ANCOVA), respectively.

RESULTS

Internal consistency of Swahili GAD-7 was good, α = 0.82 (95% CI 0.78, 0.85). Its test-retest reliability (2 weeks apart) was acceptable, ICC = 0.70 (95% CI 0.55, 0.81). A confirmatory analysis of a one-factor solution indicated an excellent fit to the hypothesized structure (RMSEA = 0.00 [95% confidence interval 0.00, 0.05], CFI = 1.00, TLI = 1.00). Multi-group CFA substantiated factorial invariance for sex and age for the one-factor structure of Swahili GAD-7. Scores of GAD-7, Swahili version, significantly correlated with those of PHQ-9 (r = 0.73; p < 0.001) and the HIV stigma scale (r = 0.36; p < 0.001) suggesting good convergent validity. Statistically significant differences were observed between participants on first-line antiretroviral therapy compared to those on second-line treatment (F [1, 441] = 5.55, p = 0.02) indicative of good discriminant validity of Swahili GAD-7.

CONCLUSION

GAD-7 Swahili version retained its original unidimensional latent structure with good psychometric properties among adults living with HIV from Kilifi, Kenya. It can be used to identify symptoms of GAD in similar research settings. However, to confidently identify those in need of mental health treatment or referral services in HIV primary care clinics, more research on the validity of Swahili GAD-7 is needed especially its discriminant validity and diagnostic accuracy at different cut-off scores.

Timing of onset and self-management of multiple chronic conditions: A qualitative examination taking a lifespan perspective

OBJECTIVES

Over two-thirds of older individuals live with multiple chronic conditions, yet chronic diseases are often studied in silos. Taking a lifespan approach to understanding the development of multiple chronic conditions in the older population helps to further elucidate opportunities for targeted interventions that address the complexities of multiple chronic conditions.

METHODS

Semi-structured interviews were conducted with 38 older adults (age 64+) diagnosed with at least two chronic health conditions. Content analysis was used to build understanding of how older adults discuss the timing of diagnoses and subsequent self-management of multiple chronic conditions.

RESULTS

Findings highlight the complex process by which illnesses unfold in the context of individuals' lives and the subsequent engagement and/or disengagement in self-management behaviors. Two primary themes were evident regarding timing of illnesses: illnesses were experienced within the context of social life events and/or health events, and illnesses were not predominantly seen as connected to one another by patients. Self-management behaviors were described in response to onset of each illness.

DISCUSSION

Findings provide insight into how older adults understand their experience of multiple chronic conditions and change in self-management behaviors over time. In order for practitioners to ignite behavioral changes, a person's history and life experiences must be considered.

Health-related quality of life and physical activity level after a behavior change program at Norwegian healthy life centers: a 15-month follow-up

Purpose

The long-term impact of primary care behavior change programs on health-related quality of life (HRQoL) and physical activity (PA) level is unknown. The aim of this study was to investigate changes in HRQoL and PA among participants after a 3-month behavior change intervention at Norwegian healthy life center (HLCs) and at a 15-month follow-up. Furthermore, we aimed to study associations between changes in PA and HRQoL.

Methods

We followed 524 adult participants (18–83 years), recruited from 32 HLCs in August 2016–January 2018, who provided data on HRQoL (SF-36) and PA (ActiGraph accelerometers) 12 months after a 3-month behavior change intervention. Changes in HRQoL and PA between baseline, 3-month and 15-month follow-ups, and associations between changes in PA and HRQoL were analyzed by linear mixed models.

Results

All HRQoL dimensions improved from baseline to 3-month follow-up, and the improvements maintained at 15-month follow-up (mean 3.1–13.1 points, p < 0.001). PA increased from baseline to 3 months (mean 418 steps/day, p < 0.001), but declined from 3 to 15 months (mean − 371 steps/day, p < 0.001). We observed positive associations between changes in PA and HRQoL (0.84–3.23 points per 1000 steps/day, p < 0.023).

Conclusions

Twelve months after completing a 3-month HLC intervention we found improved HRQoL, but not PA level. Still, there were positive associations between PA and HRQoL over this period, indicating that participants increasing their PA were more likely to improve their HRQoL.

Correlates of health-related quality of life among adults receiving combination antiretroviral therapy in coastal Kenya

Background

Health-related quality of life (HRQoL) is an important metric of perceived wellbeing in people living with HIV/AIDS (PLWHA). However, research on HRQoL among PLWHA in sub-Saharan Africa is limited. This study investigates factors associated with HRQoL among PLWHA in Kilifi, coast of Kenya.

Methods

Between February and April 2018, 450 adults living with HIV and on combined antiretroviral therapy (cART) between 18 to 60 years were sequentially recruited from an HIV-specialized clinic. The Functional Assessment of HIV Infection (FAHI) questionnaire, previously adapted for assessing HRQoL in this setting, was slightly modified and administered to participants alongside other measures of sociodemographic, health and treatment characteristics in a face-to-face interview.

Results

Linear regression analyses indicated that depressive symptoms, HIV-related stigma, non-disclosure of HIV status, living alone, clinic inaccessibility, and presence of any current opportunistic infection were significantly associated with lower HRQoL scores at both the FAHI overall and sub-scale level. Higher physician empathy, male sex, and higher body mass index were significantly associated with better HRQoL scores at both FAHI overall and sub-scale level. Age and longer duration on cART were significantly associated with better HRQoL only at the sub-scale level.

Conclusions

Interventions aimed at reducing depressive symptoms and HIV stigma, making HIV-related services more accessible, addressing opportunistic infections, strengthening social support systems, serostatus disclosure and put in place caring, respectful, and compassionate model of care are necessary to improve the HRQoL of PLWHA.

Associations between health-related quality of life, body mass index, health status and sociodemographic variables in geriatric patients and non-hospitalized older people: A comparative cross-sectional study

BACKGROUND

Data on health-related quality of life (HRQoL) in geriatric patients and non-hospitalized older people are lacking, and the associations among HRQoL, body mass index (BMI) and health status are not sufficiently investigated in these groups.

AIM

This study aims to describe and compare HRQoL in a sample of geriatric patients and non-hospitalized people >70 years. It further aims to investigate the associations between HRQoL, BMI, health status and sociodemographic variables in geriatric patients and non-hospitalized people >70 years.

METHODS

This cross-sectional study included 107 geriatric patients and 328 non-hospitalized older people. HRQoL was measured with the 36-Item Short Form Survey (SF-36) and BMI was divided into three classes: underweight (<22 kg/m²), normal weight (22-27 kg/m²) and overweight (>27 kg/m²).

RESULTS

All SF-36 scores were lower for the geriatric patients than for the non-hospitalized people (p < .001). Underweight (BMI <22 kg/m²) was registered for 43.9% of the geriatric patients and for 13.7% of the non-hospitalized people. No significant associations were found between the SF-36 subscale scores and underweight, but overweight was associated with lower scores on physical functioning (B: -8.7) and vitality (B: -6.8) compared to those with normal BMI (p < .05). The participants with rheumatic diseases, pulmonary diseases, hypertension and digestive diseases had significantly lower scores on most SF-36 scales reflecting physical health.

CONCLUSION

HRQoL is substantially lower in geriatric patients than in non-hospitalized older people. The negative effects of both overweight and morbidity on HRQoL indicate that it is important to monitor weight and disease symptoms to promote HRQoL in older people, whether hospitalized or non-hospitalized.

Multimorbidity of chronic non-communicable diseases in low- and middle-income countries: A scoping review

BACKGROUND

Multimorbidity is rising in low- and middle-income countries (LMICs). However, the evidence on its epidemiology from LMICs settings is limited and the available literature has not been synthesized as yet.

OBJECTIVES

To review the available evidence on the epidemiology of multimorbidity in LMICs.

METHODS

PubMed, Scopus, PsycINFO and Grey literature databases were searched. We followed the PRISMA-ScR reporting guideline.

RESULTS

Of 33, 110 articles retrieved, 76 studies were eligible for the epidemiology of multimorbidity. Of these 76 studies, 66 (86.8%) were individual country studies. Fifty-two (78.8%) of which were confined to only six middle-income countries: Brazil, China, South Africa, India, Mexico and Iran. The majority (n = 68, 89.5%) of the studies were crosssectional in nature. The sample size varied from 103 to 242, 952. The largest proportion (n = 33, 43.4%) of the studies enrolled adults. Marked variations existed in defining and measuring multimorbidity. The prevalence of multimorbidity in LMICs ranged from 3.2% to 90.5%.

CONCLUSION AND RECOMMENDATIONS

Studies on the epidemiology of multimorbidity in LMICs are limited and the available ones are concentrated in few countries. Despite variations in measurement and definition, studies consistently reported high prevalence of multimorbidity. Further research is urgently required to better understand the epidemiology of multimorbidity and define the best possible interventions to improve outcomes of patients with multimorbidity in LMICs.

Performance of the UKPDS Outcomes Model 2 for Predicting Death and Cardiovascular Events in Patients with Type 2 Diabetes Mellitus from a German Population-Based Cohort

BACKGROUND AND OBJECTIVE

Accurate prediction of relevant outcomes is important for targeting therapies and to support health economic evaluations of healthcare interventions in patients with diabetes. The United Kingdom Prospective Diabetes Study (UKPDS) risk equations are some of the most frequently used risk equations. This study aims to analyze the calibration and discrimination of the updated UKPDS risk equations as implemented in the UKPDS Outcomes Model 2 (UKPDS-OM2) for predicting cardiovascular (CV) events and death in patients with type 2 diabetes mellitus (T2DM) from population-based German samples.

METHODS

Analyses are based on data of 456 individuals diagnosed with T2DM who participated in two population-based studies in southern Germany (KORA (Cooperative Health Research in the Region of Augsburg)-A: 1997/1998, n = 178; KORA-S4: 1999-2001, n = 278). We compared the participants' 10-year observed incidence of mortality, CV mortality, myocardial infarction (MI), and stroke with the predicted event rate of the UKPDS-OM2. The model's calibration was evaluated by Greenwood-Nam-D'Agostino tests and discrimination was evaluated by C-statistics.

RESULTS

Of the 456 participants with T2DM (mean age 65 years, mean diabetes duration 8 years, 56% male), over the 10-year follow-up time 129 died (61 due to CV events), 64 experienced an MI, and 46 a stroke. The UKPDS-OM2 significantly over-predicted mortality and CV mortality by 25% and 28%, respectively (Greenwood-Nam-D'Agostino tests: p < 0.01), but there was no significant difference between predicted and observed MI and stroke risk. The model poorly discriminated for death (C-statistic [95% confidence interval] = 0.64 [0.60-0.69]), CV death (0.64 [0.58-0.71]), and MI (0.58 [0.52-0.66]), and failed to discriminate for stroke (0.57 [0.47-0.66]).

CONCLUSIONS

The study results demonstrate acceptable calibration and poor discrimination of the UKPDS-OM2 for predicting death and CV events in this population-based German sample. Those limitations should be considered when using the UKPDS-OM2 for economic evaluations of healthcare strategies or using the risk equations for clinical decision-making.

Measuring the impact of chronic conditions and associated multimorbidity on health-related quality of life in the general population in Hong Kong SAR, China: A cross-sectional study

Objectives

The aims of this study were to 1) evaluate the impact of eight common chronic conditions and multimorbidity on preference-based health-related quality of life (HRQoL), and 2) estimate the minimally important difference (MID) in the general population of Hong Kong (HK).

Design

Data were analyzed using secondary data analysis based on a cross-sectional, population-based validation study of HK’s general population.

Participants

A representative sample was recruited across eighteen geographical districts in HK, and 1,014 HK Chinese residents aged 18 years and older participated in the survey. The prevalence of chronic conditions among the respondents was 30.3%.

Interventions

The HRQoL was assessed using the locally validated version of EQ-5D-5L. The five-dimension descriptive system, and the utility scores of EQ-5D-5L were used as the dependent variable in the study. Eight common chronic conditions, multimorbidity, and demographic characteristics were defined as predictors in the analysis. Chi-squared test, analysis of variance (ANOVA), logistic regression, and Tobit regression models were used to analyze the data. A simulation-based approach was used to calculate the MID based on instrument-defined single level transitions.

Results

The findings indicated that respondents with physical disabilities were more likely to report problems on all five dimensions of the EQ-5D-5L than those with other chronic conditions. In addition, respondents with multiple chronic conditions were more likely to report health problems and lower utility scores of EQ-5D-5L. The mean of MID estimates among the respondents in HK was 0.093 (standard deviation = 0.001), which is higher than in other Asian countries.

Conclusions

The findings suggest that having more chronic conditions is strongly associated with a lower HRQoL. Healthcare reforms to address foreseeable challenges arising as more patients live with chronic conditions and multimorbidity could improve the HRQoL of HK citizens.

Prevalence and correlates of depressive symptoms among adults living with HIV in rural Kilifi, Kenya

BACKGROUND

Published research on depression among people living with HIV/AIDS (PLWHA) from Africa is increasing, but data from Kenya remains scarce. This cross-sectional study measured the prevalence and correlates of depressive symptoms among PLWHA in rural Kilifi, on the Kenyan coast.

METHODS

Between February and April 2018, we consecutively recruited and interviewed 450 adults living with HIV and on combination antiretroviral therapy (cART). Depressive symptoms were assessed with the 9-item Patient Health Questionnaire (PHQ-9), with a positive depression screen defined as PHQ-9 score ≥ 10. Measures of psychosocial, health, and treatment characteristics were also administered.

RESULTS

The overall prevalence of depressive symptoms was 13.8% (95% Confidence Interval (95%CI): 10.9, 17.3). Multivariable logistic regression analysis identified current comorbid chronic illness (adjusted Odds Ratio (aOR) 5.72, 95% CI: 2.28, 14.34; p < 0.001), cART regimen (aOR 6.93, 95%CI: 2.34, 20.49; p < 0.001), perceived HIV-related stigma (aOR 1.10, 95%CI: 1.05, 1.14, p < 0.001) and difficulties accessing HIV care and treatment services (aOR 2.37, 95%CI: 1.14, 4.91; p = 0.02) as correlates of depressive symptoms.

CONCLUSION

The prevalence of depressive symptoms among adults living with HIV on the Kenyan coast is high. Those at high risk for elevated depressive symptoms (e.g., with comorbid chronic illnesses, on second-line cART, experiencing perceived HIV-stigma or with problems accessing HIV care) may benefit from early identification, treatment or referral, which requires integration of mental health programmes into HIV primary care.

Factors associated with quality of life among community pharmacists in Lebanon: results of a cross-sectional study

Objective:

The objective of this study was to assess the quality of life and the factors associated with it among community pharmacists in Lebanon.

Methods:

This cross-sectional study was carried out between March and July 2018, enrolling 435 pharmacists, using a proportionate random sample of community pharmacies from all districts of Lebanon. The validated Arabic translation of the Short-Form 12 (SF12v2) was used to derive 2 summary scores: physical and mental component summaries (PCS and MCS).

Results:

Lebanese community pharmacists scored a mean PCS-12 and MCS-12 of 48.9 (SD 7.1) and 48.8 (SD 8.5), respectively. Higher age (Beta= -0.08), having a PhD degree (Beta= -4.54), higher depression score (Beta= -0.25), higher emotional work fatigue (Beta= -0.13) and higher physical work fatigue (Beta=-0.14) were significantly associated with lower physical QoL (lower PCS-12 scores). Increased stress (Beta= -0.17), higher insomnia (Beta= -0.21), higher depression (Beta= -0.2) and working for over 40 hours per week (Beta= -0.2) were significantly associated with lower mental QoL (lower mental MCS-12 scores).

Conclusions:

Our research has found a strong correlation between quality of life and psychological factors, including stress, burnout, insomnia, and depression among community pharmacists.

Effects of Chronic Comorbidities on the Health-Related Quality of Life among Older Patients after Falls in Vietnamese Hospitals

Although comorbidities are prevalent in older people experiencing falls, there is a lack of studies examining their influence on health-related quality of life (HRQOL) in this population. This study examines the prevalence of comorbidities and associations between comorbidities and HRQOL in older patients after falls in Vietnamese hospitals. A cross-sectional design was employed among 405 older patients admitted to seven hospitals due to fall injuries in Thai Binh province, Vietnam. The EuroQol-5 Dimensions-5 Levels (EQ-5D-5L) was used to measure HRQOL. Socio-demographic characteristics were collected using a structured questionnaire, while comorbidities and other clinical characteristics were examined by physicians and extracted from medical records. Multivariate Tobit regression was used to determine the associations between comorbidities and HRQOL. Among 405 patients, 75.6% had comorbidities, of which hypertension and osteoarthritis were the most common. Lumbar spine/cervical spine diseases (Coefficient (Coef.) = −0.10; 95%CI = −0.18; 0.03) and stroke (Coef. = −0.36; 95%CI = −0.61; −0.10) were found to be associated with a significantly decreased EQ-5D index. Participants with three comorbidities had EQ-5D indexes 0.20 points lower (Coef. = −0.20; 95%CI = −0.31; −0.09) in comparison with those without comorbidities. This study underlined a significantly high proportion of comorbidities in older patients hospitalized due to fall injuries in Vietnam. In addition, the existence of comorbidities was associated with deteriorating HRQOL. Frequent monitoring and screening comorbidities are critical to determining which individuals are most in need of HRQOL enhancement.

Health-related quality of life and medical comorbidities in older patients with pancreatic adenocarcinoma: An analysis using the 1998-2011 surveillance, epidemiology, and end results-medicare health outcomes survey data

OBJECTIVES

This study compares health-related quality of life (HRQoL) of older patients with pancreatic ductal adenocarcinoma (PDAC) to controls without cancer, and examines the impact of medical comorbidities on HRQoL.

MATERIALS AND METHODS

We conducted a case-control study using the 1998-2011 Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey (SEER-MHOS) linked dataset. Cases were Medicare beneficiaries aged 65 and older diagnosed with PDAC (N = 128) and matched controls were without a history of cancer (N = 512). We used the Short Form 36 (SF-36) and Veterans-RAND-12 (VR-12) to examine HRQoL and calculated mental (MCS) and physical (PCS) component scores. Linear regression and mixed effects models were used to examine the impact of medical comorbidities on MCS and PCS for cases and controls, respectively.

RESULTS

Cases reported significantly poorer PCS (29.3 vs. 36.3) and MCS (44.8 vs. 49.9) compared to controls. Comorbidities were significantly associated with lower PCS and MCS in controls. However, neither total number of comorbidities or comorbidities grouped by organ systems (cardiopulmonary disease, musculoskeletal disease, diabetes) were significantly related to PCS or MCS for cases. Comparison of regression coefficients estimates did not indicate that lack of significance was due to differences in sample size.

CONCLUSIONS

The results of this study highlight the poor HRQoL reported by older patients with PDAC. HRQoL scores were very low in this population, particularly in physical health status, which were not explained by comorbidities.

Inflammation in multimorbidity and disability: An integrative review

OBJECTIVE

Multimorbidity is a robust predictor of disability in aging adults, but the mechanisms by which multimorbidity is disabling are not clear. Most existing research focuses on disease-specific phenomena, such as diminished lung capacity in chronic obstructive pulmonary disease, which can result in functional limitations. This review takes a different approach by highlighting the potential role of a biological process-inflammation-that is common to many chronic medical conditions and thus, from a medical perspective, relatively disease nonspecific.

METHOD

Beginning with a description of inflammation and its measurement, this paper will provide an overview of research on inflammation as a predictor of disease risk in healthy adults and of adverse outcomes (e.g., disability) in those with multimorbidity.

RESULTS

The discussion of inflammation is then situated in the context of biopsychosocial influences on health, as inflammation has been shown to be sensitive to a wide range of social and psychological processes that are thought to contribute to healthy aging, including successful adaptation to multimorbidity and reduced risk of disability.

CONCLUSIONS

Finally, implications of this broader perspective for interventions to improve outcomes in aging adults with multimorbidity are briefly considered. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

The Iranian version of geriatric anxiety inventory (GAI-P): a validation study

BACKGROUND

Anxiety is one of the most common mental health problems experienced by the elderly that affects quality of life. This study aimed to assess the psychometric properties of the Persian version of the Geriatric Anxiety Inventory (GAI-P) in order to provide a valid instrument for measuring anxiety in this population.

METHODS

Forward-backward translation was used to translate the Geriatric Anxiety Inventory from English into Persian and was tested by 10 elderly to assess its face validity. Then a sample of elderly people attending health centers in Dezful, Iran completed the questionnaire. Validity was assessed using both exploratory and confirmatory factors analysis, known-groups comparison (abused and non-abused elderly) also was administered. The internal consistency of the instrument was assessed using Kuder-Richardson 20 coefficients (KR-20). Afterwards, the reliability and validity through assessing the correlation between the Persian version of the GAI-P and the SF-36, were measured.

RESULTS

In all 720 elderly completed the questionnaire. Of these data from 420 elderly were used for exploratory factor analysis and the data from the remaining 300 elderly were used for confirmatory factor analysis. The exploratory factor analysis showed a three-factor solution (cognitive, arousal and somatic) for the questionnaire that jointly explained 59.48% of the overall variance observed. The confirmatory factor analysis supported the three-factor solution and the second-order latent factor model. The findings indicated a positive and significant correlation between the two measures lending support to its concurrent validity (r = 0.67, p < .001).Ultimately, the Geriatric Anxiety Inventory was found to have a favorable internal consistency.

CONCLUSION

This study confirmed that the GAI-P is a valid measure of anxiety in elderly population and now can be used in geriatric studies in Iran.

Health related quality of life in multimorbidity: a primary-care based study from Odisha, India

BACKGROUND

Multimorbidity, the coexistence of two or more chronic conditions is increasingly prevalent in primary care populations. Despite reports on its adverse impact on health outcomes, functioning and well-being, it's association with quality of life is not well known in low and middle income countries. We assessed the health-related quality of life (HRQoL) of primary care patients with multimorbidity and identified the influencing factors.

METHODS

This cross-sectional study was done across 20 public and 20 private primary care facilities in Odisha, India. Data were collected from 1649 adult out-patients using a structured multimorbidity assessment questionnaire for primary care (MAQ-PC). HRQoL was assessed by the 12-item short-form health survey (SF-12). Both physical (PCS) and mental components scores (MCS) were calculated. Multiple regression analysis was performed to determine the association of HRQoL with socio-demographics, number, severity and typology of chronic conditions.

RESULTS

Around 28.3% [95% CI: 25.9-30.7] of patients had multimorbidity. Mean physical component scope (PCS) and mental component score (MCS) of QoL in the study population was 43.56 [95% CI: 43.26-43.86] and 43.69 [95% CI: 43.22-44.16], respectively. Patients with multimorbidity reported poorer mean PCS [43.23, 95% CI: 42.62-43.84] and MCS [41.58, 95% CI: 40.74-42.43] compared to those without. After adjusting for other variables, morbidity severity burden score was found to be negatively associated with MCS [adjusted coefficient: -0.24, 95% CI - 0.41 to - 0.08], whereas no significant association was seen with PCS. Hypertension and diabetes with arthritis and acid peptic diseases were found to be negatively related with MCS. Within multimorbidity, lower education was inversely associated with mental QoL and positively associated with physical QoL score after adjusting for other variables.

CONCLUSION

Our findings demonstrate the diverse negative effects of multimorbidity on HRQoL and reveal that apart from count of chronic conditions, severity and pattern also influence HRQoL negatively. Health care providers should consider severity as an outcome measure to improve QoL especially in individuals with physical multimorbidity. Given the differences observed between age groups, it is important to identify specific care needs for each group. Musculoskeletal clusters need prioritised attention while designing clinical guidelines for multimorbidity.

Investigating the effectiveness of an online acceptance and commitment therapy (ACT) intervention versus a waiting list control condition on pain interference and quality of life in adults with chronic pain and multimorbidity: protocol for a randomised controlled trial

INTRODUCTION

Multimorbidity refers to the presence of two or more chronic health conditions within one person, where no one condition is primary. Research suggests that multimorbidity is highly correlated with chronic pain, which is pain lasting longer than 3 months. Psychotherapeutic interventions for people living with chronic illness have resulted in reduced symptom reporting and improved psychological well-being. There is a dearth of research, however, using online psychotherapy for people living with multimorbidity where chronic pain is a central condition. This study will compare the effectiveness of an online acceptance and commitment therapy (ACT) intervention with a waiting list control condition in terms of improving health-related quality of life (HRQoL) and reducing levels of pain interference in people with chronic pain and at least one other condition.

METHODS AND ANALYSIS

192 adult participants with non-malignant pain that persists for at least 3 months and at least one other medically diagnosed condition will be randomised to one of two study conditions. The experimental group will undergo an eight-session internet-delivered ACT programme over an 8-week period. A waiting list group will be offered the ACT intervention after the 3-month follow-up period. HRQoL and pain interference will act as the primary outcomes. Data will be analysed using a linear mixed model and adjusted to account for demographic and clinical variables as necessary. A Study Within a Trial will be incorporated to examine the effect on recruitment and retention of showing participants an animated educational video.

ETHICS AND DISSEMINATION

Ethical approval has been granted by the Research Ethics Committee of the National University of Ireland, Galway. Dissemination of results will be via peer reviewed journal articles and conference presentations.

The impact of co-morbidity on the quality of life of people with dementia: findings from the IDEAL study

Background

The aim was to investigate the co-morbidity profile of people with dementia and examine the associations between severity of co-morbidity, health-related quality of life (HRQoL) and quality of life (QoL).

Methods

The improving the experience of Dementia and Enhancing Active Life (IDEAL) cohort consisted of 1,547 people diagnosed with dementia who provided information on the number and type of co-morbid conditions. Participants also provided ratings of their health-related and dementia-specific QoL.

Results

The majority of the sample were living with more than one chronic condition. Hypertension was commonly reported and frequently combined with connective tissue disease, diabetes and depression. The number of co-morbid conditions was associated with low QoL scores, and those with severe co-morbidity (≥5 conditions) showed the greatest impact on their well-being.

Conclusions

Co-morbidity is an important risk factor for poor QoL and health status in people with dementia. Greater recognition of the nature and impact of co-morbidity is needed to inform support and interventions for people with dementia and a multidisciplinary approach to care provision is recommended.

Multimorbidity and Mental Health-Related Quality of Life and Risk of Completed Suicide

BACKGROUND

Physical functioning indexed multimorbidity is strongly associated with long-term mortality, but its role in poor mental health has not been quantified.

METHODS

A total of 252 002 community-dwelling adults in the Nurses' Health Study (NHS), NHS II, and Health Professionals Follow-up Study (HPFS) prospective cohorts reported physician-diagnosed diseases and the Short Form-36 over 8 years and had 24-year follow-up for suicide mortality. We quantified multimorbidity using a multimorbidity-weighted index (MWI). We used multivariable-adjusted proportional hazards models with competing risks for suicide mortality and mixed-effects models to estimate mental health-related quality of life (HRQOL).

RESULTS

Multimorbidity was associated with an increased risk of suicide mortality in an approximately linear manner, with roughly two- to threefold higher risk in adults with the highest vs lowest quartile MWI in adjusted models: NHS hazard ratio (HR) = 3.01 (95% confidence interval [CI] = 1.48-6.11); NHS II HR = 3.04 (95% CI = 1.82-5.09); HPFS HR = 1.74 (95% CI = 1.08-2.81). Greater MWI was associated with worse mental HRQOL 8 years later across all scales and the mental component summary (MCS) in a dose-response manner. This association was attenuated but persisted after adjustment for baseline mental HRQOL and other covariates. Adults with the highest quartile MWI had lower MCS in adjusted models compared with those with the lowest quartile MWI: NHS ß = -0.61 (95% CI = -0.78 to -0.44); NHS II ß = -1.25 (95% CI = -1.44 to -1.06).

CONCLUSION

Multimorbidity is associated with substantially higher suicide mortality risk and worse mental HRQOL across all available scales, even when indexed to physical functioning. These results highlight the substantial mental health burden imposed by multimorbidity at all ages and sexes. J Am Geriatr Soc 67:511-519, 2019.

Measurement of health-related quality by multimorbidity groups in primary health care

Background

Increased life expectancy in Western societies does not necessarily mean better quality of life. To improve resources management, management systems have been set up in health systems to stratify patients according to morbidity, such as Clinical Risk Groups (CRG). The main objective of this study was to evaluate the effect of multimorbidity on health-related quality of life (HRQL) in primary care.

Methods

An observational cross-sectional study, based on a representative random sample (n = 306) of adults from a health district (N = 32,667) in east Spain (Valencian Community), was conducted in 2013. Multimorbidity was measured by stratifying the population with the CRG system into nine mean health statuses (MHS). HRQL was assessed by EQ-5D dimensions and the EQ Visual Analogue Scale (EQ VAS). The effect of the CRG system, age and gender on the utility value and VAS was analysed by multiple linear regression. A predictive analysis was run by binary logistic regression with all the sample groups classified according to the CRG system into the five HRQL dimensions by taking the “healthy” group as a reference. Multivariate logistic regression studied the joint influence of the nine CRG system MHS, age and gender on the five EQ-5D dimensions.

Results

Of the 306 subjects, 165 were female (mean age of 53). The most affected dimension was pain/discomfort (53%), followed by anxiety/depression (42%). The EQ-5D utility value and EQ VAS progressively lowered for the MHS with higher morbidity, except for MHS 6, more affected in the five dimensions, save self-care, which exceeded MHS 7 patients who were older, and MHS 8 and 9 patients, whose condition was more serious. The CRG system alone was the variable that best explained health problems in HRQL with 17%, which rose to 21% when associated with female gender. Age explained only 4%.

Conclusions

This work demonstrates that the multimorbidity groups obtained by the CRG classification system can be used as an overall indicator of HRQL. These utility values can be employed for health policy decisions based on cost-effectiveness to estimate incremental quality-adjusted life years (QALY) with routinely e-health data.

Patients under 65 years with multimorbidity perceived worse HRQL than older patients or disease severity. Knowledge of multimorbidity with a stronger impact can help primary healthcare doctors to pay attention to these population groups.

Neuropsychology of aging

All people want to age "successfully," maintaining functional capacity and quality of life as they reach advanced age. Achieving this goal depends on preserving optimal cognitive and brain functioning. Yet, significant individual differences exist in this regard. Some older adults continue to retain most cognitive abilities throughout their lifetime. Others experience declines in cognitive and functional capacity that range from mild decrements in certain cognitive functions over time to severe dementia among those with neurodegenerative diseases. Even among relatively healthy "successful agers," certain cognitive functions are reduced from earlier levels. This is particularly true for cognitive functions that are dependent on cognitive processing speed and efficiency. Working memory and executive and attentional functions tend to be most vulnerable. Learning and memory functions are also usually reduced, although in the absence of neurodegenerative disease learning and retrieval efficiency rather than memory storage are affected. Other functions, such as visual perception, language, semantics, and knowledge, are often well preserved. Structural, functional, and physiologic/metabolic brain changes correspond with age-associated cognitive decline. Physiologic and metabolic mechanisms, such as oxidative stress and neuroinflammation, may contribute to these changes, along with the contribution of comorbidities that secondarily affect the brain of older adults. Cognitive frailty often corresponds with physical frailty, both affected by multiple exogenous and endogenous factors. Neuropsychologic assessment provides a way of measuring the cognitive and functional status of older adults, which is useful for monitoring changes that may be occurring. Neuroimaging is also useful for characterizing age-associated structural, functional, physiologic, and metabolic brain changes, including alterations in cerebral blood flow and metabolite concentrations. Some interventions that may enhance cognitive function, such as cognitive training, neuromodulation, and pharmacologic approaches, exist or are being developed. Yet, preventing, slowing, and reversing the adverse effects of cognitive aging remains a challenge.

Exploring Different Strategies of Assessing the Economic Impact of Multiple Diabetes-Associated Complications and Their Interactions: A Large Claims-Based Study in Germany

BACKGROUND

In the context of an aging population with increasing diabetes prevalence, people are living longer with diabetes, which leads to increased multimorbidity and economic burden.

OBJECTIVE

The primary aim was to explore different strategies that address the economic impact of multiple type 2 diabetes-related complications and their interactions.

METHODS

We used a generalized estimating equations approach based on nationwide statutory health insurance data from 316,220 patients with type 2 diabetes (baseline year 2012, 3 years of follow-up). We estimated annual total costs (in 2015 euros) for type 2 diabetes-related complications and, in addition, explored different strategies to assess diabetes-related multimorbidity: number of prevalent complications, co-occurrence of micro- and macrovascular complications, disease-disease interactions of prevalent complications, and interactions between prevalent/incident complications.

RESULTS

The increased number of complications was significantly associated with higher total costs. Further assessment of interactions showed that macrovascular complications (e.g., chronic heart failure) and high-cost complications (e.g., end-stage renal disease, amputation) led to significant positive effects of interactions on costs, whereas early microvascular complications (e.g., retinopathy) caused negative interactions. The chronology of the onset of these complications turned out to have an additional impact on the interactions and their effect on total costs.

CONCLUSIONS

Health economic diabetes models and evaluations of interventions in patients with diabetes-related complications should pay more attention to the economic effect of specific disease interactions. Politically, our findings support the development of more integrated diabetes care programs that take better account of multimorbidity. Further observational studies are needed to elucidate the shared pathogenic mechanisms of diabetes complications.

A Subjective Quality of Life Proxy for Older Adults in the PAQUID Cohort Study

OBJECTIVES

Quality of life is regarded as a major outcome in epidemiologic research, especially in the older population. Nevertheless, some cohort studies lack a specific instrument to evaluate it. The aim of this study was to propose a subjective quality of life proxy using easily accessible items, available in most epidemiologic studies.

METHOD

We used data from the PAQUID (Personnes Agées Quid) cohort study (1991-1992, France). A subjective quality of life proxy was created based on items on positive affects, subjective health, and life satisfaction. Logistic and linear regression models as well as Cox survival models were used to assess the association between the proxy score and depression, dependence, cognitive complaints, adverse life events, comorbidities, and death. Analyses were replicated in an independent cohort study, AMI (Approche Multidisciplinaire intégrée; 2007-2008, France). All models were adjusted for age, sex, Mini-Mental State Examination score, and place of residence.

RESULTS

In the PAQUID sample (n = 2135), we found significant associations between the proxy score and the selected health outcomes. We found the same associations in the AMI cohort.

CONCLUSION

This proxy might be useful when no gold standard for quality of life assessment is available or when in need of a short but reliable instrument that will not require extended administration time.

Multimorbidity and health-related quality of life in Koreans aged 50 or older using KNHANES 2013-2014

Background

Multimorbidity negatively affects health outcomes and impairs health-related quality of life (HRQoL). We assessed the prevalence of multimorbidity in Koreans aged 50 and older, taking into consideration their socioeconomic status, and estimated the loss in HRQoL due to multimorbidity.

Methods

This study is based on an analysis of data for adults aged 50 and older derived from the cross-sectional nationally representative Korean National Health and Nutrition Examination Survey conducted in 2013–14. The five most prevalent chronic diseases and disease dyads were identified. The impact of the degree of multimorbidity, sex, and socioeconomic status on the European Quality of Life 5 Dimension (EQ-5D) index score were analyzed. Marital status, educational attainment, household income, basic livelihood security benefit, and occupation were considered as socioeconomic factors.

Results

The analysis included 5996 adults aged 50 years and older with males comprising 46.6%. Two or more chronic diseases were present in 26.8% of the participants aged 50 and older and 37.9% of the participants aged 65 and older. The most prevalent dyadic combination was hypertension and dyslipidemia in the 50 and older group, and hypertension and osteoarthritis in the 65 and older age group. Hypertension dominated the multimorbidity combinations (four of the five most prevalent multimorbidity dyads), while a few conditions such as osteoarthritis had a relatively large influence on quality of life. In addition to the degree of multimorbidity, female and lower socioeconomic status were associated with significantly lower EQ-5D index scores.

Conclusions

Integrated, holistic healthcare based on a patient-oriented perspective for earlier, more effective intervention, targeting multimorbidity is warranted. Special consideration should be given to patients with low socioeconomic status.

[Impact of cardiovascular risk factors on the consumption of resources in Primary Care according to Clinical Risk Groups]

Objetivo

Analizar en el contexto de una Zona Básica de Salud (ZBS) la prevalencia de los factores de riesgo cardiovascular (FRCV) y el impacto que generan en la morbilidad y el consumo de recursos sanitarios en la población estratificada según el sistema Clinical Risk Groups (CRG) en Atención Primaria (AP), con la finalidad de identificar la población con multimorbilidad para aplicar medidas preventivas, así como aquella que genera más carga asistencial y necesidades sociales.

Diseño

Estudio observacional, de corte transversal y ámbito poblacional para una ZBS durante el año 2013.

Emplazamiento

Departamento de salud de Castellón, Comunidad Valenciana (CV). Incluye asistencia ambulatoria en AP y especializada.

Participantes

Todos los ciudadanos dados de alta en el Sistema de Información Poblacional (SIP), N = 32.667.

Mediciones

Del sistema informatizado Abucasis obtuvimos las variables demográficas, clínicas y de consumo de recursos sanitarios. Consideramos la prevalencia de los FRCV a partir de la presencia o ausencia de los códigos diagnósticos CIE.9.MC. Se analizó la relación de los FRCV con los 9 estados de salud CRG, y se realizó un análisis predictivo con el modelo de regresión logística para evaluar la capacidad explicativa de cada variable. Además se obtuvo mediante regresión multivariante un modelo explicativo del gasto farmaceútico ambulatorio.

Resultados

La población del estado de salud CRG 4 en adelante tenía multimorbilidad. Los estados de salud CRG 7 y CRG 6 tienen mayor prevalencia de FRCV. Fue predictivo que a mayor morbilidad, mayor consumo de recursos, mediante OR superiores a la media, p < 0,05 e intervalos de confianza del 95%. Se observó que un 59,8% del gasto farmacéutico ambulatorio quedaba explicado por el sistema CRG y todos los FRCV (p < 0,05 y R² corregido = 0,598). En cuanto al efecto de los FRCV sobre los estados de salud CRG, hubo asociación significativa (p < 0,05) para la alteración de la glucemia, dislipidemia e HTA en todos los estados CRG.

Conclusiones

El estudio de los FRCV en una población estratificada mediante el sistema CRG identifica y predice dónde se genera mayor impacto en la morbilidad y consumo de recursos sanitarios. Nos permite conocer los grupos de pacientes en quienes desarrollar estrategias de prevención y cronicidad. A nivel de la práctica clínica se aporta un nuevo concepto de multimorbilidad, definido a partir del estado de salud CRG 4 en adelante.
