"The 3/3 strategy": a successful multifaceted hospital wide hand hygiene intervention based on WHO and continuous quality improvement methodology.

BACKGROUND Only multifaceted hospital wide interventions have been successful in achieving sustained improvements in hand hygiene (HH) compliance. METHODOLOGY/PRINCIPAL FINDINGS Pre-post intervention study of HH performance at baseline (October 2007-December 2009) and during intervention, which included two phases. Phase 1 (2010) included multimodal WHO approach. Phase 2 (2011) added Continuous Quality Improvement (CQI) tools and was based on: a) Increase of alcohol hand rub (AHR) solution placement (from 0.57 dispensers/bed to 1.56); b) Increase in frequency of audits (three days every three weeks: "3/3 strategy"); c) Implementation of a standardized register form of HH corrective actions; d) Statistical Process Control (SPC) as time series analysis methodology through appropriate control charts. During the intervention period we performed 819 scheduled direct observation audits which provided data from 11,714 HH opportunities. The most remarkable findings were: a) significant improvements in HH compliance with respect to baseline (25% mean increase); b) sustained high level (82%) of HH compliance during intervention; c) significant increase in AHRs consumption over time; c) significant decrease in the rate of healthcare-acquired MRSA; d) small but significant improvements in HH compliance when comparing phase 2 to phase 1 [79.5% (95% CI: 78.2-80.7) vs 84.6% (95% CI:83.8-85.4), p<0.05]; e) successful use of control charts to identify significant negative and positive deviations (special causes) related to the HH compliance process over time ("positive": 90.1% as highest HH compliance coinciding with the "World hygiene day"; and "negative":73.7% as lowest HH compliance coinciding with a statutory lay-off proceeding). CONCLUSIONS/SIGNIFICANCE CQI tools may be a key addition to WHO strategy to maintain a good HH performance over time. In addition, SPC has shown to be a powerful methodology to detect special causes in HH performance (positive and negative) and to help establishing adequate feedback to healthcare workers.

Lung cancer in HIV-infected patients

Purpose: Several studies have shown that HIV patients are at higher risk of lung cancer. Our aim is to analyse the prevalence and features of lung cancer in HIV-infected patients. Methods: The clinical charts of 4,721 HIV-infected patients seen in three hospitals of southeast Spain (study period 1992-2012) were reviewed, and all patients with a lung cancer were analysed. Results: There were 61 lung cancers, giving a prevalence of 1.2%. There was a predominance of men (82.0%), and smokers (96.6%; mean pack-years 35.2), with a median age of 48.0 (41.7-52.9) years, and their distribution according to risk group for HIV was: intravenous drug use 58.3%, homosexual 20.0%, and heterosexual 16.7%. Thirty-four (56.7%) patients were Aids cases, and 29 (47.5%) had prior pulmonar events: tuberculosis 16, bacterial pneumonia 9, and P. jiroveci pneumonia 4. The median nadir CD4 count was 149/mm3 (42-232), the median CD4 count at the time of diagnosis of the lung cancer was 237/mm3 (85-397), and 66.1% <350/mm3. 66.7% were on ART, and 70% of them had undetectable HIV viral load. The most common histological types of lung cancer were adenocarcinoma and epidermoid, with 24 (40.0%) and 23 (38.3%) cases, respectively. There were 49 (80.3%) cases with advanced stages (III and IV) at diagnosis. The distribution of treatments was: only palliative 23 (39.7%), chemotherapy 14 (24.1%), surgery and chemotherapy 8 (13.8%), radiotherapy 7 (12.1%), surgery 4 (6.9%), and other combined treatments 2 (3.4%). Forty-six (76.7%) patients died, with a median survival time of 3 months. The Kaplan-Meier survival rate at 6 months was 42.7% (at 12 months 28.5%). Conclusions: The prevalence of lung cancer in this cohort of HIV-patients is high. People affected are mainly men, smokers, with transmission of HIV by intravenous drug use, and around half of them with prior opportunistic pulmonary events. Most patients had low nadir CD4 count, and were immunosuppressed at the time of diagnosis. Adenocarcinoma is the most frequent histological type. The diagnosis is usually made at advanced stages of the neoplasm, and mortality is high.

Efficacy of two educational interventions about inhalation techniques in patients with chronic obstructive pulmonary disease (COPD). TECEPOC: study protocol for a partially randomized controlled trial (preference trial).

BACKGROUND Drugs for inhalation are the cornerstone of therapy in obstructive lung disease. We have observed that up to 75 % of patients do not perform a correct inhalation technique. The inability of patients to correctly use their inhaler device may be a direct consequence of insufficient or poor inhaler technique instruction. The objective of this study is to test the efficacy of two educational interventions to improve the inhalation techniques in patients with Chronic Obstructive Pulmonary Disease (COPD). METHODS This study uses both a multicenter patients´ preference trial and a comprehensive cohort design with 495 COPD-diagnosed patients selected by a non-probabilistic method of sampling from seven Primary Care Centers. The participants will be divided into two groups and five arms. The two groups are: 1) the patients´ preference group with two arms and 2) the randomized group with three arms. In the preference group, the two arms correspond to the two educational interventions (Intervention A and Intervention B) designed for this study. In the randomized group the three arms comprise: intervention A, intervention B and a control arm. Intervention A is written information (a leaflet describing the correct inhalation techniques). Intervention B is written information about inhalation techniques plus training by an instructor. Every patient in each group will be visited six times during the year of the study at health care center. DISCUSSION Our hypothesis is that the application of two educational interventions in patients with COPD who are treated with inhaled therapy will increase the number of patients who perform a correct inhalation technique by at least 25 %. We will evaluate the effectiveness of these interventions on patient inhalation technique improvement, considering that it will be adequate and feasible within the context of clinical practice.

Estudio sobre EPOC y Atención Primaria

Study on the likelihood and prevalence of patients with copd, over a year in a family medicine consultation, during 2012 and first two months of 2013. In a query of a health center about 15oo patients every 6 months probabilistic evolution was studied according to the theory of Laplace. Analyze both the COPD, its symptoms, etiology, clinical consultation and treatment in Family Medicine.
