- Clinical Adverse Events in Elderly Hospitalized Patients in a Medical Ward - a Prospective StudyPublication . Vieira Alves, R; Fernandes, M; Figueiredo, I; Drummond Borges, D; Antunes, MIntroduction: Studies to date describe between 3% to 50% of patients experiencing one or more clinical adverse event (CAE) during their hospital admission and many preventable. The aim of this prospective study was to determine the frequency of medical CAEs in a medical ward. Also the study aimed to compare data between patient age groups and determine the effect on length of hospital stay and mortality. Methods: This is a prospective study, consulting patients’ electronic clinical notes over 6 months . Every week, all patient electronic processes were reviewed, and CAEs noted. The episode was only noted if the episode was clearly labeled as a CAEs by the medical team in the patient´s notes. If confounding factors were present, this episode was excluded. Patients were grouped by age; compared in terms of demographics, comorbidities, diagnosis at admission and readmission rate. Primary outcomes included mean length of stay and mortality. Results: 62 episodes were studied, 14.8% of those admitted to hospital experienced a CAE. The most frequent adverse events included analytical alterations, anemia and blood loss, infection and altered state of consciousness. The most commonly implicated therapies were anticoagulants (23%) which lead to episodes of bleeding, anti-hypertensive and diuretics (17%) immunosuppressive therapy (16%) beta blockers (1%) and insulin (1%). Mean length of stay in hospital was 17 days in all groups, longer than the average length of stay of this medical ward which is 11 days. Mortality rate within one year of hospitalization was 30% in total, again significantly higher than the 10% mortality rate calculated for the same period on the ward. Conclusion: This study demonstrates that CAEs are still far too common, probably underestimated, cause serious harm to patients and strains healthcare services further.
- Pneumocystosis Pneumonia: A Comparison Study Between HIV and Non-HIV Immunocompromised PatientsPublication . Rego de Figueiredo, I; Vieira Alves, R; Drummond Borges, D; Torres, M; Lourenço, F; Antunes, AM; Gruner, H; Panarra, APneumocystis pneumonia (PCP) is caused by the fungus Pneumocystis jirovecii, and its incidence has been on the rise in immunosuppressed patients without HIV. We performed a cross sectional study in patients with PCP and assessed demographic, clinical presentation and outcome measures such as mechanical ventilation and mortality differences between HIV and non-HIV patients. The two groups were statistically significantly different, with the HIV group being younger (45.5 years vs 55.9 years, p-value 0.001) and mostly composed of male patients (69% vs 31%, p-value <0.001). Also, the HIV patients had higher percentage of respiratory complaints (90% vs 68%, p-value 0.02) and lactate dehydrogenase elevation (73% vs 40%, p-value 0.001). In contrast, non-HIV patients had worse outcomes with higher incidence of invasive mechanical ventilation (23% vs 46%, p-value 0.005) and in-hospital mortality (13% vs 37%, p-value 0.002). These results reflect the literature and should raise awareness to a potentially fatal medical situation of increasing incidence.
- Readmissions in Elderly Patients with Heart Failure. A Retrospective StudyPublication . Vieira Alves, R; Fernandes, M; Figueiredo, I; Drummond Borges, D; Lourenço, FHeart failure is a major cause of morbidity and mortality worldwide. The prevalence increases with age and usually progresses, leading to repeated hospital admissions and significant symptom burden for patients. The correct management of these patients may decrease readmissions and increase quality of life. Our aim is to compare elderly patients with and without 1-year readmissions in an internal medicine ward, particularly in terms of mortality. Retrospective study, consulting patient’s clinical records, with a diagnosis of heart failure. The patients were characterized and divided in groups: with (wR) and without readmission (woR) within 1 year. Mortality was the primary outcome. Eighty-nine patients were included; 60 woR and 29 wR. There was no gender dif ference between groups, the wR group had older patients. The most frequent comor bidities included atrial fibrillation, hyper tension and chronic renal failure stage 3 or higher. The most frequent cause of hospitalization was heart failure due to insufficient therapy or natural progression of the dis ease. The etiology of heart failure was mainly hypertensive and ischemic. The wR group had more patients classified as NYHA >III . In relation to the primary outcome; mortality at 12 months was higher in the group with repeated admissions . The characterization of this population allows us to highlight the causes of decompensation and to review medication in order to increase the quality of life.
- Tuberculosis Infection in HIV Vs Non‐HIV PatientsPublication . Rego de Figueiredo, I; Branco Ferrão, J; Dias, S; Vieira Alves, R; Drummond Borges, D; Torres, M; Guerreiro Castro, S; Lourenço, F; Antunes, AM; Gruner, H; Panarra, AObjectives: Tuberculosis (TB) is the most common opportunistic infection and cause of mortality among people living with HIV, and it is possible that it may also influence the evolution of the HIV infection. We assessed the differences between HIV-positive and -negative people infected with TB. Methods: The present study is a cross-sectional retrospective study by electronic record revision. We included patients admitted to a tertiary hospital with a diagnosis of TB between 2011 and 2016, comparing those with HIV coinfection with non-HIV patients, according to demographic and clinical characteristics. Results: This study included 591 patients, of whom 32% were HIV-coinfected. HIV-TB patients were younger, with a predominance of male gender. Considering TB risk factors, there was a higher prevalence of homelessness and intravenous drug use in the HIV group. In the non-HIV group, direct contact with other patients with TB and immunosuppression were more prevalent. Relative to TB characteristics, the HIV-coinfected group presents with a higher prevalence of disseminated disease and a higher occurrence of previous TB infection. Cancer was the most frequent cause of immunosuppression in the HIV group and the number testing positive for TB via microbiological culture was lower. Assessment of microbiological resistance and in-hospital mortality showed similar numbers in both groups. Conclusions: There are few papers comparing clinical course of TB between HIV-infected and non-infected patients. Our study differs from others in the literature as we focused on a country with middling incidence of TB and further characterized the differences between HIV-infected and non-infected patients which can contribute to the management of these patients.
