Urinary tract infection: a cohort of older people with urinary incontinence / Infección del tracto urinario: cohorte de ancianos con incontinencia urinaria / Infecção do trato urinário: uma coorte de idosos com incontinência urinária

ABSTRACT Objective: To evaluate epidemiological aspects of urinary tract infection in older patients with urinary incontinence living in long-term care institutions in Belo Horizonte. Method: Concurrent cohort held from April 1st to October 1st, 2015. The study was conducted in two long-term care institutions in the city of Belo Horizonte, Minas Gerais, with 84 incontinent older people. Results: Cumulative incidence of urinary tract infection was 19% (95% CI: 7.83-23.19) and the incidence density was 3.6 cases/100 people-month of follow-up period. The variables Bacteriuria and Institution presented statistical association with the occurrence of urinary tract infection. Conclusion: It is observed that the incidence of urinary tract infection in the study was smaller than in other similar international and national studies, however this is an important world health problem for the older population, with impact on mortality of these individuals.

RESUMEN Objetivo: Analizar los aspectos epidemiológicos de infección del tracto urinario en ancianos con incontinencia urinaria, en residencias para ancianos de Belo Horizonte, Brasil. Método: Se realizó una cohorte del 1º de abril al 1º de octubre de 2015. Se realizó el estudio en dos residencias para ancianos de la ciudad de Belo Horizonte, del cual participaron 84 ancianos con incontinencia urinaria. Resultados: La incidencia acumulada de infección en el tracto urinario fue del 19% (IC 95%: 7,83-23,19) y la densidad de la incidencia fue de 3,6 casos/100 personas-mes por seguimiento. Las variables Bacteriuria y la residencia presentaron asociación estadística en la aparición de este tipo de infección. Conclusión: A pesar de que la incidencia de infección del tracto urinario en este estudio fue menor que en otros estudios nacionales e internacionales de mismo tema, es un grave problema de salud para los ancianos por todo el mundo, puesto que implica la mortalidad de ellos.

RESUMO Objetivo: Avaliar aspectos epidemiológicos da infecção do trato urinário em pacientes idosos com incontinência urinária, residentes em instituições de longa permanência, de Belo Horizonte. Método: Coorte concorrente realizada no período de 01 de abril a 01 de outubro de 2015. O estudo foi realizado em duas instituições de longa permanência, na cidade de Belo Horizonte, MG, com 84 idosos incontinentes. Resultados: A incidência acumulada de infecção do trato urinário foi de 19% (IC 95%: 7,83-23,19) e a densidade de incidência foi de 3,6 casos/100 pessoas-mês de seguimento. As variáveis Bacteriúria e Instituição apresentaram associação estatística com a ocorrência de infecção do trato urinário.

Relationship Between Status of Physical and Mental Function and Quality of Life Among the Elderly People Admitted from Long-Term Care Insurance / 예방의학회지

OBJECTIVES: This study was performed to determine the levels of quality of life (QOL) according to the grade of long-term care service for the elderly people who were admitted from long-term care insurance, and to reveal its association with the physical and mental functioning such as the Activity of Daily Living (ADL), the Instrumental Activity of Daily Living (IADL), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Mini-Mental State Examination-Korean version (MMSE-K). METHODS: The interviews were performed during the period from March 1 to May 31, 2009, for 958 elderly people in urban and rural areas. The questionnaire items included various indices such as the ADL, IADL, CES-D, and MMSE-K, as independent variables and the index of QOL, as the dependent ones. For statistical analysis, t-tests were used for the mean scores of QOL according to gender and the grade of long-term care services, and Spearman's correlation was used for each variable. The effects of physical and mental functioning for QOL were assessed by covariance structure analysis. The statistical significance was set at p<0.05. RESULTS: The mean scores of QOL among all the subjects was 55.4 +/- 15.62 (Grade I: 49.7 +/- 14.17, Grade II: 56.8 +/- 14.62, Grade III: 59.4+/-16.36), and it was lower according to the higher grade of long-term care insurance. In terms of the correlation matrix of the QOL and the physical and mental function factors, the QOL showed positive correlation with the ADL, IADL and MMSE-K, while it had negative correlation with depression. On the analysis of covariance, mental functioning (depression and the MMSE-K) had a greater influence on the level of QOL than the physical functioning (ADL and IADL). CONCLUSIONS: The level of the QOL in the elderly people who were admitted from long-term care insurance was lower according to higher the grade of long-term care insurance. Also, the mental functioning (depression and MMSE-K) was more influential on the level of the QOL than the physical functioning (ADL and IADL).
