Pharmacotherapeutic follow-up of a patient with multimorbities: experience report / Acompanhamento farmacoterapêutico em paciente com multimorbidades: um relato de experiência / Seguimiento farmacoterapéutico en pacientes con multimorbilidad: informe de una experiencia

Chronic non-communicable diseases are growing global health problems. The objective of this study was to promote pharmaceutical care for a patient with multimorbidities in order to improve its quality of life. A pharmacotherapeutic follow-up was performed using the SOAP method, registered in the form of clinical evolution, along with laboratory tests, anthropometric measurements and application of validated instruments to assess pharmacological adherence, mental health and quality of life. The report deals with a female patient, 55 years old, obese and dyslipidemic, sedentary, hypertensive, diabetic and on the control phase of breast cancer. Self-medication with antibiotics and a proton pump inhibitor was identified. Despite the good pharmacological adherence, the patient had decompensated diabetes, accompanied by dyslipidemia without treatment and interruption of supplements. After pharmacological and non- pharmacological interventions, the patient showed a significant improvement in the reduction of anthropometric measurements and in biochemical parameters. At the end of the follow-up, pharmaceutical care proved to be fundamental in identifying the patient's health problems, contributing to obtain a more rational pharmacotherapy.

Estimativa de multimorbidade em jovens brasileiros: resultados da Pesquisa Nacional de Saúde 2019 / Estimated multimorbity among young Brazilians: results of the 2019 National Health Survey

Resumo A multimorbidade, presença de duas ou mais doenças crônicas não transmissíveis, está diretamente associada a fatores comportamentais. O objetivo da pesquisa foi estimar a prevalência de multimorbidade em jovens brasileiros relacionando-a aos diferentes determinantes sociais e de estilo de vida. Trata-se de um estudo transversal cuja fonte de dados foi a Pesquisa Nacional de Saúde em 2019. Foram selecionados dados de indivíduos com idade entre 15 e 24 anos (n = 10.460). Os fatores associados foram investigados por meio do cálculo da razão de prevalência com variância robusta, adequado para análise bivariada e multivariada. A prevalência de multimorbidade nos jovens foi estimada em 7,84% (IC95%: 7,01-8,75; N: 2.455.097). Os agravos mais comuns foram doenças mentais, depressão, asma ou bronquite e problemas crônicos de coluna. No modelo ajustado, jovens do sexo feminino (RP: 1,84; IC95%: 1,44-2,36), obesos (RP: 1,97; IC95%: 1,45-2,68) e ex-fumantes (RP: 1,46; IC95%: 1,12-1,90) apresentaram maiores prevalências para multimorbidade. A razão de prevalência para multimorbidade aumentou 5% a cada ano de vida do indivíduo. Este estudo identificou uma associação de multimorbidade com determinantes sociais e estilo de vida.

Abstract Multimorbidity, namely the presence of two or more chronic non-communicable diseases, is directly associated with behavioral factors. This study sought to estimate the prevalence of multimorbidity among young Brazilians by linking it to different social and lifestyle determinants. It involved a cross-sectional study of the data source, namely the 2019 National Health Survey. Data from individuals aged between 15 and 24 years (n = 10,460) were selected. Associated factors were investigated by calculating the Prevalence Ratio with robust variance, suitable for bivariate and multivariate analysis. The prevalence of multimorbidity in young people was estimated at 7.84% (95%CI: 7.01-8.75; N: 2,455,097). The most common conditions were mental illness, depression, asthma or bronchitis and chronic back problems. In the adjusted model, young females (PR: 1.84; 95%CI: 1.44-2.36), obese youths (PR: 1.97; 95%CI: 1.45-2.68) and former smokers (PR: 1.46; 95%CI: 1.12-1.90) showed a higher prevalence of multimorbidity. It was also revealed that the prevalence ratio for multimorbidity increased by 5% for each year of the individual's life. This study identified an association of multimorbidity with social determinants and lifestyle.

Influência de padrões de multimorbidade nas atividades de vida diária da pessoa idosa: seguimento de nove anos do Estudo Fibra / Influence of multimorbidity patterns on the activities in the day-to-day lives of the elderly: nine-year follow-up of the Fibra Study

Resumo O objetivo foi avaliar a influência da multimorbidade e seus padrões nas atividades básicas de vida diária da pessoa idosa residente na comunidade. Trata-se de estudo de coorte com dados provenientes do Estudo FIBRA, linha de base (2008-2009) e seguimento (2016-2017). As atividades básicas de vida diária (ABVD) foram avaliadas pelo questionário de Katz e as doenças crônicas foram classificadas como (1) multimorbidade e padrões de multimorbidade: (2) cardiopulmonar; (3) vascular-metabólico; e (4) mental-musculoesquelético. Para a análise de dados, utilizou-se o teste qui-quadrado e a regressão de Poisson. Foram analisados 861 indivíduos sem limitação para ABVD na linha de base. As pessoas idosas com multimorbidade (RR = 1,58; IC95%: 1,19-2,10) e classificados nos padrões cardiopulmonar (RR = 2,43; IC95%: 1,77-3,33), vascular-metabólico (RR = 1,50; IC95%: 1,19-1,89) e mental-musculoesquelético (RR = 1,30; IC95%: 1,03-1,65) tiveram maior risco de apresentar declínio funcional nas ABVD no seguimento em comparação aos que não tinham os mesmos padrões de doenças. A multimorbidade e seus padrões aumentaram o risco de incapacidade na pessoa idosa ao longo de nove anos.

Abstract The scope of this article was to evaluate the influence of multimorbidity and associated effects on the activities in the day-to-day lives of community-dwelling elderly individuals. It involved a cohort study with data from the FIBRA Study, the baseline (2008-2009) and follow-up (2016-2017). The basic activities in daily living (ADL) were evaluated using Katz's index, and the chronic diseases were classified as: (1) multimorbidity and multimorbidity patterns; (2) cardiopulmonary; (3) vascular-metabolic; and (4) mental-musculoskeletal. The chi-square test and Poisson regression data were used for analysis. A total of 861 older adults with no functional dependency at baseline were analyzed. Elderly individuals with multimorbidity (RR = 1.58; 95%CI: 1.19-2.10) and classified according to cardiopulmonary (RR = 2.43; 95%CI: 1.77-3.33), vascular-metabolic (RR = 1.50; 95%CI: 1.19-1.89) and mental-musculoskeletal (RR = 1.30; 95%CI: 1.03-1.65) had a higher risk of presenting functional decline in ADL in the follow-up compared to those who didn't have the same disease patterns. Multimorbidity and its patterns increased the risk of functional disability in older adults over the nine-year period.

Use of structural models to elucidate the occurrence of falls among older adults according to abdominal obesity: a cross-sectional study

Abstract BACKGROUND: Obesity is a risk factor for falls in older adults, but the effects of body fat distribution and its interaction with other factors are not well established. OBJECTIVES: To verify the occurrence of falls among older adults with and without abdominal obesity and the effects of sociodemographic, health, and behavioral variables on this outcome. DESIGN AND SETTING: A cross-sectional study in an urban area of Alcobaça, Brazil. METHODS: Men and women older than 60 years with (270) and without (184) abdominal obesity were included. Sociodemographic, health, and behavioral data were collected using validated questionnaires in Brazil. Descriptive and path analyses were performed (P < 0.05). RESULTS: The occurrence of falls was high in participants with abdominal obesity (33.0%). In both groups, a higher number of morbidities (β = 0.25, P < 0.001; β = 0.26, P = 0.002) was directly associated with a higher occurrence of falls. Among participants without abdominal obesity, a lower number of medications (β = -0.16; P = 0.04), a higher number of depressive symptoms (β = 0.15; P = 0.04), worse performance on the agility and dynamic balance tests (β = 0.37; P < 0.001), and lower functional disability for basic activities of daily living (β = -0.21; P = 0.006) were directly associated with the occurrence of falls. CONCLUSION: Adults older than 60 years with abdominal obesity have a higher prevalence of falls. Different factors were associated with the occurrence of falls in both groups.

Association of Multimorbidity with Health Outcomes in the Chinese Middle-aged and Elderly Population / 中山大学学报(医学科学版)

ObjectiveTo analyze the multimorbidity and comorbid disease patterns among middle-aged and older adults aged 50 years and above in China and to study the prevalence， regional distribution， and relationship with health-related outcomes of major comorbid disease patterns. MethodsThe fourth national follow-up data of the China Health and Retirement Longitudinal Study （CHARLS） 2018 was used， including 13 774 respondents aged 50 years and older from 28 provincial units. We analyzed 14 patient-reported physician-diagnosed chronic diseases and multimorbidity combinations， reported prevalence， composition ratio， and regional distribution. Differences in health loss and risk factors between high morbidity groups were analyzed using chi-square tests and logistic regression. ResultsThe prevalence of multimorbidities among participants was 57.3%. The single disease with high prevalence included arthritis/rheumatism （6.47%）， hypertension （5.41%）， and gastric and digestive disorders （4.17%）； the binary multimorbidity combinations were arthritis + digestive disorders （3.06%）， arthritis + hypertension （2.61%）， and hypertension + hyperlipidemia （1.39%）； the triadic combinations were hypertension + digestive disorders + joint disorders （1.00%）. The prevalence of multimorbidity varied greatly between provinces， showing the characteristics of high in the west and north but low in the east and south China. Significant differences in the health loss caused by different multimorbidity combinations were noted， with the highest ADL loss （28.51%） and depression （77.68%） caused by the arthritis multimorbidity combinations （P<0.01）. The number of chronic diseases （OR=6.71， P<0.01）， age （OR=1.96， P<0.01）， and heavy alcohol consumption were comorbid risk factors for physical and mental health； exercise （OR=0.44， P<0.01） and sleep （OR=0.89， P<0.01） were protective factors for physical and mental health， and smoking cessation （OR=0.76， P<0.01） contributed to the relief of anxiety.

Development of a Chinese version of the Stress Adaption Scale and the assessment of its reliability and validity among Chinese patients with multimorbidity / 浙江大学学报·医学版

OBJECTIVES@#To develop a Chinese version of the Stress Adaption Scale (SAS) and to assess its reliability and validity among Chinese patients with multimorbidity.@*METHODS@#The Brislin model was used to translate, synthesize, back-translate, and cross culturally adapt the SAS. A total of 323 multimorbidity patients selected by convenience sampling method from four hospitals in Zhejiang province. The critical ratio method, total question correlation method, and graded response model (item characteristic curve and item discrimination) were used for item analysis. Cronbach's alpha coefficient and split-half reliability were used for the reliability analysis. Content validity analysis, structural validity analysis, and criterion association validity analysis were performed by expert scoring method, confirmatory factor analysis, and Pearson correlation coefficient method, respectively.@*RESULTS@#The Chinese version of the SAS contained 2 dimensions of resilience and thriving, with a total of 10 items. In the item analysis, the critical ratio method showed that the critical ratio of all items was greater than 3.0 (P<0.001); the correlation coefficient method showed that the Pearson correlation coefficients for all items exceeded 0.4 (P<0.01). The graded response model showed that items of the revised scale exhibited distinct item characteristic curves and all items had discrimination parameters exceeding 1.0. In the reliability analysis, Cronbach's alpha coefficient of the revised Chinese version of the SAS scale was 0.849, and the split-half reliability was 0.873. In the validity analysis, the item-level content validity index and scale-level content validity index both exceeded 0.80. In the confirmatory factor analysis, the revised two-factor model showed satisfactory fit indices (χ2/df=3.115, RMSEA=0.081, RMR=0.046, GFI=0.937, AGFI=0.898, CFI=0.936, TLI=0.915). In the criterion-related validity analysis, the Chinese version of the SAS score was negatively correlated with the Perceived Stress Scale and the Treatment Burden Questionnaire, with correlation coefficients of －0.592 and －0.482, respectively (both P<0.01).@*CONCLUSIONS@#The Chinese version of the SAS has good reliability and validity, which can be used to evaluate the stress adaption capacity among multimorbidity patients in China, and provides a reference for developing individualized health management measures.

Multimorbidity patterns: obesity as the main modifiable risk factor in adult women in Southern Brazil

ABSTRACT Objective: To identify multimorbidity patterns in women in southern Brazil, and its relationship with sociodemographic, lifestyle characteristics, and nutritional status, as well as to explore the main independent risk factor for the identified patterns. Subjects and methods: This is a cross-sectional, population-based study with 1,128 women (20-69 years), southern Brazil. Chronic conditions were identified using the therapeutic and chemical anatomical classification of continuous use of medications. Multimorbidity was assessed as ≥2 or ≥3 chronic conditions to identify dyads and triads. Poisson regression was used to explore risk factors in the different adjustment models. As independent variables evaluated, in addition to sociodemographic characteristics, lifestyle variables were included: consumption of fruits and vegetables, physical activity, alcohol consumption, smoking and nutritional status. Results: Eleven dyads (frequencies between 2.0% and 6.4%) and three triads (frequencies between 1.9% and 2.1%) of morbidities were identified in the study. Aging was related to a higher prevalence of all patterns, and obesity was a risk factor for multimorbidity patterns that contained conditions related to the cardiovascular and metabolic system and mental health. After adjustment, obesity increased the probability of "hypertension + common mental disorders (CMD)" (PR 3.63; 95% CI 1.94-6.78) and "dyslipidemia + CMD" (PR 3.69; 95% CI 1.08-12.65) by more than three times. Conclusion: This study identified common and important diseases in the patterns, associated with a common risk factor, obesity, that must be addressed by public health policies to prevent multimorbidity.

Association between multimorbidity, intensive care unit admission, and death in patients with COVID-19 in Brazil: a cross-section study, 2020

ABSTRACT BACKGROUND: Multimorbidity can influence intensive care unit (ICU) admissions and deaths due to coronavirus disease (COVID-19). OBJECTIVE: To analyze the association between multimorbidity, ICU admissions, and deaths due to COVID-19 in Brazil. DESIGN AND SETTING: This cross-sectional study was conducted using data from patients with severe acute respiratory syndrome (SARS) due to COVID-19 recorded in the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) in 2020. METHODS: Descriptive and stratified analyses of multimorbidity were performed based on sociodemographic, ventilatory support, and diagnostic variables. Poisson regression was used to estimate the prevalence ratios. RESULTS: We identified 671,593 cases of SARS caused by COVID-19, of which 62.4% had at least one morbidity. Multimorbidity was associated with male sex, age 60-70 and ≥ 80 years, brown and black skin color, elementary education and high school, ventilatory support, and altered radiologic exams. Moreover, all regions of the country and altered computed tomography due to COVID-19 or other diseases were associated with death; only the northeast region and higher education were associated with ICU admission. CONCLUSION: Our results showed an association between multimorbidity, ICU admission, and death in COVID-19 patients in Brazil.

Prevalence, associated factors and patterns of multimorbidity of non-communicable diseases among adults in Shaanxi Province / 西安交通大学学报(医学版)

【Objective】 To estimate the prevalence, associated factors and patterns of multimorbidity of non-communicable diseases among adults in Shaanxi Province so as to provide evidence for the prevention and control of non-communicable diseases. 【Methods】 We used the data of adults aged 18 years and older collected in the baseline survey of Shaanxi Project in the Regional Ethnic Cohort Study in Northwest China. Multinomial logistic regression was used to explore the associated factors for multimorbidity. Exploratory factor analysis was used to extract patterns of multimorbidity. 【Results】 The prevalence of multimorbidity was 10.7% among the 44 442 participants. Age increase, being males, urban residence, and being overweight or obesity were positively associated with multimorbidity. Compared with women, men had a higher risk of multimorbidity. The OR and 95% CI was 1.25 (1.12-1.39). The risk of multimorbidity increased with age among adults. Compared with participants aged 18.0-34.9 years, the ORs and 95% CIs of those aged 35.0-44.9, 45.0-54.9, 55.0-64.9, and ≥65.0 years were 4.73 (3.47-6.46), 15.61 (11.60-21.00), 41.39 (30.76-55.70) and 90.04 (66.58-121.77), respectively. The primary multimorbidity patterns among adults in Shaanxi were cardiovascular-metabolic multimorbidity (5.4%), viscero-articular multimorbidity (1.0%), and respiratory multimorbidity (0.3%). 【Conclusion】 More than one in ten adults in Shaanxi Province had multimorbidity, and the predominant pattern of multimorbidity was cardiovascular-metabolic multimorbidity. The prevention and control of non-communicable diseases should be reinforced in middle-aged and older people, males, people living in the urban, and overweight or obese people. More attention should be paid to the prevention and control of cardiovascular-metabolic diseases.

Research progress on the interrelation between multiple chronic conditions and sleep disorders / 中华全科医师杂志

Multiple chronic conditions have become prominent health problems nowadays. There is a positive correlation between the number of chronic diseases and the risk of sleep disorders. Patients with sleep disorders will also be more difficult to control chronic diseases they have. Therefore, more attention should be paid to the sleep problems in patients with multimorbidity. This article discusses the interrelation between multimorbidity and sleep disorders from various dimensions, to provide a new vision for the prevention and treatment of sleep disorders in patients with multimorbidity.

Visualized analysis on trend and hot spot of research on multimorbidity using knowledge map / 中华全科医师杂志

Objective:To analyze the trend and hot spots of research on multimorbidity.Methods:The Chinese and English literature in databases of CNKI, Wanfang data and Web of science from inception to July 2022 were retrieved using "multimorbidity" and "multiple chronic conditions" as the search terms. The scientific knowledge mapping software VOSviewer was used to analyze the co-occurrence network of scientific knowledge from the aspects of countries, Chinese and English keywords,burst terms and existing research results; and the status quo and hot trends of studies on multimorbidity at home and abroad were summarized and compared.Results:A total of 251 Chinese publications and 6 351 English publications were included. From the perspective of research trends, the overall trend of domestic and international publications showed a fluctuating upward trend in general, but the pace of development was different. The cooperation network represented by the United States, England, Canada, China, Japan, Australia and other countries was the largest regional cooperation network. Germany, the Netherlands, the United States, Australia and other countries were the first regions to carry out studies on multimorbidity. Studies on multimorbidity in China mainly focused on three topics: diagnosis, treatment and care of multimorbidity, common disease management of multimorbidity, and research methods of multimorbidity. The English literature mainly focused on the clustering of three topics: multi-disease co-diagnosis and care research, multi-disease co-management model research, and multimorbidity related research. The analysis of burst terms indicated the research focus and trend change in different time periods. The results of the outburst word analysis showed that the recent research hotspots of multimorbidity were public health, machine learning, geriatric medicine and so on.Conclusions:The number of studies on the multimorbidity is rapidly increasing both domestically and internationally, and related research in China is still in the early stages of development. In terms of research hotspots, the research of multimorbidity has gradually shifted from phenomenon description to topics such as medical services and research methods of multimorbidity.
