Experience of Using an App in HIV Patients Older Than 60 Years: Pilot Program.

BACKGROUND: New technologies can promote knowledge of HIV infection among patients suffering from this disease. Older patients with HIV infection represent an increasingly large group that could benefit from the use of specific apps. OBJECTIVE: The aim of the study was to observe the acceptability and use of a mobile app on HIV infection in patients at least 60 years old and offer them the possibility of anonymously establishing contact with their peers. METHODS: A series of clinical and psychosocial parameters were studied in 30 HIV-infected patients of over 60 years. The patients must be at least 60 years old, with a follow-up in the outpatient clinic for at least 1 year and without pathologies that limit his or her life expectancy to less than a year. They must know how to read and write. To be part of the group assigned to the app, they had to have their own smartphone and confirm that they were connected to the internet from that device. Overall, 15 of them were randomized to use an app and 15 were in the control group. All tests were repeated after 6 months. RESULTS: The median age of patients was 66.5 years. Among them, 29 patients had an undetectable viral load at baseline. The median number of comorbid diseases was 2. Overall, 11 of them lived with their partners and 19 lived alone. They spent an average of 5 hours a day sitting down, and 56% (17/30) of them referred high physical activity. They scored 4 out of 5 for general quality of life perception. Moreover, 80% (24/30) presented high adherence to their treatment, and the average number of concomitant medications was 5. In the 6-min walking test, they covered a distance of 400 meters, and 3 of them desaturated during the test. The 15 patients made frequent use of the app, with 2407 sessions and an average of 7 min and 56 seconds time of use with a total of 13,143 screen views. During the 6 months of the trial, 3 non-AIDS events took place. There were no significant modifications to body mass index, blood pressure measurements, lipid profile, or immuno-virology information data. There were no differences in the questionnaire scores for perception of quality of life, confessed physical activity, or antiretroviral treatment (ART) and non-ART treatment adherence. CONCLUSIONS: Significant differences between studied parameters were not objectified in these patients, possibly because this trial has significant limitations, such as a small sample size and only a brief follow-up period. However, patients did use the app frequently, making this a possible intervention to be proposed in future subsequent studies.

Uso del índice tobillo-brazo en la reclasificación del riesgo vascular en pacientes con infección VIH / Ankle-brachial index in the assessment of cardiovascular risk among HIV infected patients

Background: Vascular risk is an important cause of morbidity and mortality in HIV infected patients. Aim: To study the value of the ankle-brachial index (ABI) in vascular risk stratification in a cohort of people with HIV infection. Patients and Methods: Vascular risk was calculated in all the patients that agreed to participate in the study and clinical reports were reviewed retrospectively. Ten year risk of fatal myocardial infarction was calculated according to Framingham equation, National Cholesterol Education Program (NCEP) III and Systematic Coronary Risk Evaluation (SCORE) project score. ABI was calculated measuring resting systolic blood pressure at the ankle, that was compared with the systolic brachial pressure. The ratio of the two pressures defined ABI, that was considered abnormal if it was d" 0.9 or e" 1.3. Results: A total of 231 HIV infected patients aged 23 to 82 years (80 percent males) were enrolled. Ten years risk according to Framingham equation was 8.4 percent, 95 percent confidence intervals (CI): 7.54-9.15 and according to SCORE scale was 0.8 percent, 95 percent CI: 0.62-1.01. According to NCEP III 9 percent of patients had a high or very high cardiovascular risk. Median ABI was 1.17 (95 percent CI intervals: 1.16-1.19) and 58 patients (25 percent) had an abnormal value. Using ABI results, approximately 20 percent of patients were re-classified as having a high vascular risk. Conclusions: ABI identified approximately 20 percent of this cohort of HIV infected subjects as having high vascular risk.

[Results of a counselling programme in antibiotic treatment in a secondary hospital]. / Programa de asesoramiento en tratamiento antibiótico en un hospital de segundo nivel: resultados de un año de actuación.

BACKGROUND: The inappropriate use of antimicrobial agents may contribute to the development of bacterial resistance to the principal antimicrobial drugs. There is no provision in the immediate future of marketing of new broad-spectrum antibiotics, especially with activity against Enterobacteriaceae, so programs should be implemented to optimize antimicrobial therapy. We describe the results of a year of a counselling program in antibiotic treatment in a secondary Andalusian hospital. METHODS: We describe 276 interventions of a multidisciplinary non-compulsory counselling program of antimicrobial management on the Costa del Sol Hospital in Marbella. We evaluated the adequacy of empirical treatment, possibility of antibiotic de-escalation, duration and dose used. We analyzed the evolution of the sensitivity profile of the main microorganisms as well as a cost-effective analysis. RESULTS: 90% of the recommendations were accepted. The main actions were assessment of empirical therapy and deescalation in relation with the result of cultures. The main drugs tested were imipenem, meropenem, cefepime, and linezolid. The sensitivity profile of imipenem and meropenem improved slightly over previous years. It was found a considerable savings in annual drug spending. CONCLUSIONS: The non-compulsory counselling programs are useful tools for optimization of antimicrobial therapy, can prevent an increase of antimicrobial resistance and reduce the cost of antibiotic treatment.

Gestión clínica: estrategias, instrumentos e incentivos / Clinical management: estrategy, instruments and incentive

La gestión clínica es un tema de gran actualidad que ha irrumpido con fuerza en el debate sanitario. La mayor parte de las actuales propuestas de reforma tienen en común el considerar que es necesario descentralizar las organizaciones sanitarias y que el profecional debe participar en la gestión de los recursos que utiliza en su práctica clínica. A diferencia de otras propuestas de reforma en el hospital, esta iniciativa ha ilusionado a los profecionales porque la gestión clínica habla de clínica y pacientes, ha adoptado el lenguaje de los profecionales y se fundamenta en principios éticos, científicos y asistenciales además de económicos. Representa un cambio cultural, a largo plazo, en el que lo importante es la tenacidad, la c0nstancia y la produncia para evitar el descrédito de la propuesta. Para que los profecionales desarrollen gestión clínica necesitan tener el mejor nivel de conocimiento de medicina o de enfermería, disponer de los instrumentos necesarios y un entorno de motivación adecuado
