RECALMIN. Four years of growth of the internal medicine units of the Spanish National Health System (2013-2016). / RECALMIN. Cuatro años de evolución de las Unidades de Medicina Interna del Sistema Nacional de Salud (2013-2016).

OBJECTIVES: To compare the structure, resources and activity of the internal medicine units (IMUs) of the Spanish National Health System (SNHS) in 2013 and 2016. To analyse the differences between IMUs in 2016 by hospital size. MATERIAL AND METHODS: We conducted a comparison of 2 descriptive cross-sectional studies of IMUs in general acute care hospitals of the Spanish National Health System, with data referring to 2013 and 2016. The variables were collected via an ad hoc questionnaire (RECALMIN survey). RESULTS: Between 2013 and 2016, the demand for care increased dramatically (with an annual average of 11% in hospital discharges and 16% in first consultations), and comorbidity slightly increased (2%). During this period, the mean productivity of IMUs increased 16.7% (0.6±0.3 vs. 0.7±0.3; P=.09), and the mean stay decreased 10% (9±2.2 vs. 8.1±2.1 days; P=.001). Progress in implementing good practices and systematic care for complex chronic patients was scarce. Both surveys found variability among IMUs and marked differences among IMUs of hospitals of different sizes. CONCLUSIONS: IMUs responded to the increased burden of care they supported during 2013-2016 by improving their efficiency and productivity; however, advances in implementing good practices, including care for chronic complex patients, were scare. The significant variability in the indicators of structure, activity and management models found in 2013 remained in 2016.

Update on the risk stratification of acute symptomatic pulmonary thromboembolism. / Actualización en la estratificación de riesgo del tromboembolismo pulmonar agudo sintomático.

Early mortality in patients with pulmonary thromboembolism (PTE) varies from 2% in normotensive patients to 30% in patients with cardiogenic shock. The current risk stratification for symptomatic PTE includes 4 patient groups, and the recommended therapeutic strategies are based on this stratification. Patients who have haemodynamic instability are considered at high risk. Fibrinolytic treatment is recommended for these patients. In normotensive patients, risk stratification helps differentiate between those of low risk, intermediate-low risk and intermediate-high risk. There is currently insufficient evidence on the benefit of intensive monitoring and fibrinolytic treatment in patients with intermediate-high risk. For low-risk patients, standard anticoagulation is indicated. Early discharge with outpatient management may be considered, although its benefit has still not been firmly established.

Feasibility of adequate resectable rectal cancer treatment in a third-level hospital.

PURPOSE: The aim of this study was to determine the feasibility, concerning compliance to protocol and recommended clinical practice guidelines, as well as efficacy results of multidisciplinary treatment (surgery, radiotherapy and chemotherapy) of resectable rectal cancer in a third-level hospital devoid of radiotherapy and clinical oncology units. PATIENTS AND METHODS: A retrospective, single-institution analysis was completed for 45 consecutive patients diagnosed with resectable rectal cancer who entered an officially proposed multidisciplinary treatment protocol from October 1998 to September 2003. Adequacy of patient inclusion, according to clinical stage, was reviewed. Neoadjuvant radiotherapy schedule, surgery procedures and adjuvant chemotherapy indication were assessed. All treatment time intervals were analysed. Finally, efficacy results are discussed and contextualised by comparison with results of clinical trials which support this treatment strategy. RESULTS: According to an independent board review, 3 patients (6.7%) with stage I rectal cancer, 31 patients (68.9%) with stage II and 11 patients (24.4%) with stage III rectal cancer were included. Radiotherapy dosage, volume and schedule were as planned. Median time from diagnosis to start of radiotherapy was 26.36 days (24.26- 28.57; CI 95%). Median duration of radiotherapy was 6.00 days (5.56-6.44; CI 95%). Median time from start of radiotherapy to surgery was 15.67 days (14.47-16.87; CI 95%). Median time from completion of radiotherapy to surgery was 10.67 days (9.53-11.81; CI 95%). Most of the patients underwent low anterior resection [23 patients (51.2%)] and abdominoperineal resection [16 patients (35.6%)]. Correlation between clinical and pathologic staging was as expected. Twenty-nine patients (64.4%) of the 45 that were initially included started adjuvant chemotherapy. A statistically significant relationship between pathologic stage (grouped I-II vs. III) and the use of adjuvant chemotherapy was found (p=0.033; chi-square test). Radiotherapy- and chemotherapy-induced toxicity did not differ from that previously reported. With a median follow-up of 65.46 months, a total of 10 recurrences have been diagnosed, all of them in stage III patients. Overall survival rate at five years was 76% for the complete population included. CONCLUSION: Multidisciplinary treatment of resectable rectal cancer in a third-level hospital is feasible. Although efficacy results are comparable to those previously reported in the literature, further improvements in clinical staging as well as in adjuvant chemotherapy indication are desirable.

Clinical presentation of HIV infection in patients aged 50 years or older.

OBJECTIVES: To describe the clinical presentation of HIV disease in older patients. METHODS: In the period 1989-1996 we reviewed the medical records of 100 patients with human immunodeficiency virus (HIV) infection aged 50 years or older and, 197 controls among HIV-infected patients aged 15-40 years, who attended six institutions in the autonomous community of Valencia (Spain). RESULTS: Older patients were mostly males (86%), men who have sex with men (42%) or unknown (20%) as exposure categories. Older patients had lower CD4 cell counts/mm3 (163+/-136 vs. 450+/-373, P= 0.008), and had AIDS at first evaluation (49% vs. 29%, P = 0.0006) compared with younger patients. For patients presenting with AIDS at HIV infection diagnosis, type and frequency of AIDS indicator diseases did not differ between older and younger patients. CONCLUSION: Studies on clues for early detection of HIV infection in patients aged 50 years or older are urgently needed to improve the health care in this population.
