Prevalência e fatores associados a amputações por pé diabético / The prevalence and factors associated with diabetic foot amputations

O objetivo desta investigação foi determinar a prevalência de amputações por pé diabético e analisar associações com fatores relacionados à pessoa e à atenção básica. Estudo epidemiológico de corte transversal. A amostra compreendeu 214 portadores de pé diabéticos internados em um dos quatro hospitais com especialidade cirurgia vascular de Pernambuco. Os dados foram coletados mediante questionário semiestruturado. Na análise dos dados foram aplicados os procedimentos da estatística descritiva, análise de associações de qui-quadrado e de regressão de poisson (p < 0,05). A prevalência de amputações encontrada foi de 50%. Estiveram associados à sua ocorrência fatores relacionados à pessoa: baixa escolaridade (p = 0,027), duas ou mais pessoas residentes no domicílio (p = 0,046) e renda do paciente inferior a um salário mínimo (p = 0,004). Dos fatores relacionados à atenção básica: não ter os pés examinados (RP = 1,17) e não ter recebido orientações sobre os cuidados com os pés (RP = 2,24) nas consultas realizadas no último ano, além de não usar o medicamento para controle do DM conforme prescrição (RP = 1,60) e controle inadequado da glicemia (RP = 1,83) foram associados à ocorrência de amputações. A compreensão desses fatores ajuda a identificar aspectos da assistência preventiva que precisam ser melhorados.

The scope of this investigation was to establish the prevalence of diabetic foot amputations and analyze associations with factors related to the individual and to primary health care. It is a cross-sectional epidemiological study and the sample included 214 inpatients with diabetic feet in one of the four hospitals specialized in vascular surgery in the state of Pernambuco. Data were collected using semi-structured questionnaires. In the data analysis, chi-square association, Poisson regression (p < 0.05) and descriptive statistics procedures were applied. The prevalence of amputation ascertained was 50%. The following factors related to the individual were associated with its occurrence: low education (p = 0.027); two or more people living in the household (p = 0.046); and patient income below the minimum wage (p = 0.004). The following factors related to primary health care were associated with amputation: not having feet examined (PR = 1.17); not receiving guidance on foot care (PR = 2.24) in consultations in the past year; not using the drug for DM control as prescribed (PR = 1.60); and inadequate glycemic control (PR = 1.83). Understanding these factors helps to identify aspects of preventive care that require improvement.

Diabetic foot complications among patients attending a specialist diabetes clinic in Jamaica: prevalence and associated factors / Complicaciones del pie diabético entre pacientes que asistían a una clínica especializada de diabetes en Jamaica: prevalencia y pactores asociados

OBJECTIVES: To estimate the prevalence of diabetic foot complications among patients at a specialist diabetes clinic in Jamaica and identify factors associated with foot complications. METHODS: A stratified random sample of 188 patients were interviewed and examined between 2009 and 2010. Trained nurses obtained demographic and clinical data, measured anthropometrics and performed foot examinations including inspection for amputations, ulcers or infection and assessment of pain, vibration and pressure perception. RESULTS: Participants included 143 women and 45 men (mean age 56 years; mean diabetes duration 16 years). The prevalence of amputations was 8.5% (95% CI 4.5, 12.5%) and was higher among men (22.2%) compared to women (4.2%, p < 0.05). Prevalence of current ulcers and current foot infections was 4.3% and 3.7%, respectively. Overall, 12% of patients had at least one of these foot complications. Foot complications were more prevalent among men, patients with high blood pressure (BP > 130/80 mmHg) or peripheral neuropathy. In multivariable logistic regression models, factors associated with foot complications were: neuropathy (OR 9.3 [95% CI 2.8, 30.3]), high BP (OR 7.9 [1.3, 49.7]) and diabetes duration (OR 1.32 [1.02, 1.72]). CONCLUSION: Approximately one of every eight patients in this specialist clinic had a major foot complication. Associated factors were neuropathy, high blood pressure and longer duration of diabetes.

OBJETIVOS: Estimar la prevalencia de complicaciones de pie diabético entre pacientes de una clínica especializada en diabetes en Jamaica, e identificar los factores asociados con complicaciones de pie. SUJETOS Y MÉTODOS: Se realizaron entrevistas y exámenes a una muestra aleatoria estratificada de 188 pacientes entre 2009 y 2010. Enfermeras entrenadas obtuvieron datos demográficos y clínicos, realizaron mediciones antropométricas, así como exámenes de pie - incluyendo la inspección de las amputaciones, las úlceras o infección, y evaluación de la percepción del dolor, la vibración y la presión. RESULTADOS: Los participantes incluyeron 143 mujeres y 45 hombres (edad promedio: 56 años; duración promedio de la diabetes: 16 años). La prevalencia de las amputaciones fue 8.5% (IC de 95%: 4.5, 12.5%) y fue mayor entre los hombres (22.2%) en comparación con las mujeres (4.2%, p < 0.05). La prevalencia de las úlceras e infecciones de pie corrientes fue de 4.3% y 3.7%, respectivamente. En general, 12% de los pacientes tenían al menos una de estas complicaciones de pie. Las complicaciones de pie fueron más frecuentes entre los hombres, los pacientes con hipertensión arterial (BP > 130/80 mmHg), o con neuropatía periférica. De acuerdo con los modelos de regresión logística multivariable, los factores asociados con las complicaciones de pie fueron: la neuropatía (OR 9.3 [95% CI 2.8, 30.3]), BP alto (OR 7.9 [1.3, 49.7]) y la duración de la diabetes (OR 1.32 [1.02, 1.72]). CONCLUSIÓN: Aproximadamente uno de cada ocho pacientes en esta clínica especializada tuvo una complicación de pie importante. Los factores asociados fueron: neuropatía, presión alta y mayor duración de la diabetes.
