Hypogammaglobulinemia after front-line immunochemotherapy in patients with follicular lymphoma.

INTRODUCTION: Hypogammaglobulinemia after front-line immunochemotherapy for follicular lymphoma is a poorly studied adverse event that could be related to the appearance of severe and/or recurrent non-neutropenic infections which could affect the quality of life of the patients, even motivating a need of long-term replacement therapy with human immunoglobulins. METHODS: Observational, retrospective study aiming to estimate the incidence of hypogammaglobulinemia, as well as its severity and clinical consequences, and to explore possible predictive factors for its development. Specific immunoglobulin deficiencies were also studied. RESULTS: 76.5% of patients had hypogammaglobulinemia during or after front-line treatment, mostly grade 1-2; with 38.8% patients who developed clinically relevant infections and 20% patients requiring human immunoglobulins replacement therapy. A high-risk FLIPI score was identified as a risk factor for hypogammaglobulinemia (ods ratio: 4.51; 95% confidence interval: 1.29-15.68; p < 0.001) and basal gamma globulin level as a protective factor (odds ratio: 0.92; 95% confidence interval: 0.988-0.996; p = 0.018). Any type of immunochemotherapy regimen was associated with different risks of hypogammaglobulinemia in our study. CONCLUSIONS: Hypogammaglobulinemia appears in a high percentage of patients with follicular lymphoma in a real-world population, identifying a high-risk FLIPI score as a risk factor for its development and basal gamma globulins as a protective factor.

Effectiveness and safety of eribulin for human epidermal growth factor receptor 2 negative metastatic breast cancer in a real-world population.

BACKGROUND: Eribulin's clinical benefit remains unclear; so, studies analyzing its effectiveness in routine clinical practice are interesting. PATIENTS AND METHODS: This is a multicenter, retrospective study including patients with human epidermal growth factor receptor-2-negative metastatic breast cancer which assesses effectiveness and safety of eribulin. RESULTS: A total of 140 women were included, with a median age of 57 years. The median overall survival and progression-free survival were 8.8 (95% confidence interval: 6.1-11.4) and 2.8 months (95% confidence interval: 2.5-3.1), respectively. For patients with hormonal receptor expression, a significantly longer progression-free survival was observed: 3.4 (95%confidence interval: 2.3-4.5) versus triple negative: 2.0 (95%confidence interval: 1.7-2.3) months, p = 0.003. Also, those who had received capecitabine prior to eribulin had a higher median overall survival than those who had not received it (9.5 months, 95% confidence interval: 6.6-12.5 vs. 4.8 months, 95% confidence interval: 3.4-6.2; p = 0.001). When only triple-negative patients were included, median overall survival was 6.5 (95% confidence interval: 0.1-16.2) for those who had received previous capecitabine versus 4.3 (95% confidence interval: 2.8-5.8) months for patients who had not received it; p =0.006. The safety profile of eribulin was adequate. CONCLUSION: Effectiveness of eribulin in a real-life human epidermal growth factor receptor-2--negative population is lower than that observed in clinical trials. Its benefit seems to be higher in patients with hormonal receptor expression and patients who had received capecitabine prior to eribulin. The safety profile of eribulin is adequate.

Long-Term Impact of an Educational Antimicrobial Stewardship Program on Hospital-Acquired Candidemia and Multidrug-Resistant Bloodstream Infections: A Quasi-Experimental Study of Interrupted Time-Series Analysis.

BACKGROUND: The global crisis of bacterial resistance urges the scientific community to implement intervention programs in healthcare facilities to promote an appropriate use of antibiotics. However, the clinical benefits or the impact on resistance of these interventions has not been definitively proved. METHODS: We designed a quasi-experimental intervention study with an interrupted time-series analysis. A multidisciplinary team conducted a multifaceted educational intervention in our tertiary-care hospital over a 5-year period. The main activity of the program consisted of peer-to-peer educational interviews between counselors and prescribers from all departments to reinforce the principles of the proper use of antibiotics. We assessed antibiotic consumption, incidence density of Candida and multidrug-resistant (MDR) bacteria bloodstream infections (BSIs) and their crude death rate per 1000 occupied bed days (OBDs). RESULTS: A quick and intense reduction in antibiotic consumption occurred 6 months after the implementation of the intervention (change in level, -216.8 defined daily doses per 1000 OBDs; 95% confidence interval, -347.5 to -86.1), and was sustained during subsequent years (average reduction, -19,9%). In addition, the increasing trend observed in the preintervention period for the incidence density of candidemia and MDR BSI (+0.018 cases per 1000 OBDs per quarter; 95% confidence interval, -.003 to .039) reverted toward a decreasing trend of -0.130 per quarter (change in slope, -0.029; -.051 to -.008), and so did the mortality rate (change in slope, -0.015; -.021 to -.008). CONCLUSIONS: This education-based antimicrobial stewardship program was effective in decreasing the incidence and mortality rate of hospital-acquired candidemia and MDR BSI through sustained reduction in antibiotic use.

Time to positivity of blood cultures in patients with bloodstream infections: A useful prognostic tool.

OBJECTIVE: The time to positivity (TTP) of blood cultures in patients with bloodstream infections (BSIs) has been considered to be a possible prognostic tool for some bacterial species. However, notable differences have been found between sampling designs and statistical methods in published studies to date, which makes it difficult to compare results or to derive reliable conclusions. Our objective was to evaluate the clinical and microbiological implications of TTP among patients with BSI caused by the most common pathogens. METHODS: A total of 361 episodes of BSI were reported for 332 patients. The survival of the entire cohort was measured from the time of blood culture sampling. In order to compare our results with those of previous studies, TTP was divided in three different groups based on log rank (short TTP <12h; medium TTP ≥12h to ≤27h, and long TTP >27h). Cox proportional hazard models were used to calculate crude and adjusted hazard ratios (HR). RESULTS: The Cox proportional hazard model revealed that TTP is an independent predictor of mortality (HR=1.00, p=0.031) in patients with BSIs. A higher mortality was found in the group of patients with the shortest TTP (<12h) (HR=2.100, p=0.047), as well as those with longest TTP (>27h) (HR=3.277, p=0.031). CONCLUSIONS: It seems that TTP may provide a useful prognostic tool associated with a higher risk of mortality, not only in patients with shorter TTP, but also in those with longer TTP.

Acinetobacter baumannii in critically ill patients: Molecular epidemiology, clinical features and predictors of mortality.

INTRODUCTION: The main aim of this study was to assess changes in the epidemiology and clinical presentation of Acinetobacter baumannii over a 10-year period, as well as risk factors of mortality in infected patients. METHOD: Prospective, multicentre, hospital-based cohort studies including critically ill patients with A. baumannii isolated from any clinical sample were included. These were divided into a first period ("2000 study") (one month), and a second period ("2010 study") (two months). Molecular typing was performed by REP-PCR, PFGE and MSLT. The primary endpoint was 30-day mortality. RESULTS: In 2000 and 2010, 103 and 108 patients were included, and the incidence of A. baumannii colonization/infection in the ICU decreased in 2010 (1.23 vs. 4.35 cases/1000 patient-days; p<0.0001). No differences were found in the colonization rates (44.3 vs. 38.6%) or infected patients (55.7 vs. 61.4%) in both periods. Overall, 30-day mortality was similar in both periods (29.1 vs. 27.8%). The rate of pneumonia increased from 46.2 in 2000 to 64.8% in 2010 (p<0.001). Performing MSLT, 18 different sequence types (ST) were identified (18 in 2000, 8 in 2010), but ST2 and ST79 were the predominant clones. ST2 isolates in the ICU increased from 53.4% in the year 2000 to 73.8% in 2010 (p=0.002). In patients with A. baumannii infection, the multivariate analysis identified appropriate antimicrobial therapy and ST79 clonal group as protective factors for mortality. CONCLUSIONS: At 10 years of the first analysis, some variations have been observed in the epidemiology of A. baumannii in the ICU, with no changes in mortality. Epidemic ST79 clone seems to be associated with a better prognosis and adequate treatment is crucial in terms of survival.

Adequate antibiotic therapy prior to ICU admission in patients with severe sepsis and septic shock reduces hospital mortality.

INTRODUCTION: In patients with severe sepsis and septic shock as cause of Intensive Care Unit (ICU) admission, we analyze the impact on mortality of adequate antimicrobial therapy initiated before ICU admission. METHODS: We conducted a prospective observational study enrolling patients admitted to the ICU with severe sepsis or septic shock from January 2008 to September 2013. The primary end-point was in-hospital mortality. We considered two groups for comparisons: patients who received adequate antibiotic treatment before or after the admission to the ICU. RESULTS: A total of 926 septic patients were admitted to ICU, and 638 (68.8%) had available microbiological isolation: 444 (69.6%) received adequate empirical antimicrobial treatment prior to ICU and 194 (30.4%) after admission. Global hospital mortality in patients that received treatment before ICU admission, between 0-6h ICU, 6-12h ICU, 12-24h ICU and after 24 hours since ICU admission were 31.3, 53.2, 57.1, 50 and 50.8% (p<0.001). The multivariate analysis showed that urinary focus (odds ratio (OR) 0.20; 0.09-0.42; p<0.001) and adequate treatment prior to ICU admission (OR 0.37; 0.24-0.56; p<0.001) were protective factors whereas APACHE II score (OR 1.10; 1.07-1.14; p<0.001), septic shock (OR 2.47; 1.57-3.87; p<0.001), respiratory source (OR 1.91; 1.12-3.21; p=0.016), cirrhosis (OR 3.74; 1.60-8.76; p=0.002) and malignancy (OR 1.65; 1.02-2.70; p=0.042) were variables independently associated with in-hospital mortality. Adequate treatment prior to ICU was a protective factor for mortality in patients with severe sepsis (n=236) or in septic shock (n=402). CONCLUSIONS: The administration of adequate antimicrobial therapy before ICU admission is decisive for the survival of patients with severe sepsis and septic shock. Our efforts should be directed to assure the correct administration antibiotics before ICU admission in patients with sepsis.

Prognostic and diagnostic value of eosinopenia, C-reactive protein, procalcitonin, and circulating cell-free DNA in critically ill patients admitted with suspicion of sepsis.

INTRODUCTION: The aims of this study were to assess the reliability of circulating cell-free DNA (cf-DNA) concentrations, compared with C-reactive protein (CRP), procalcitonin (PCT) and eosinophil count, in the diagnosis of infections in patients with systemic inflammatory response syndrome (SIRS) and their prognostic values in a cohort of critically ill patients. METHODS: We conducted a prospective cohort study in a medical-surgical intensive care unit of a university hospital. Eosinophil count and concentrations of cf-DNA, CRP, and PCT were measured in patients who fulfilled SIRS criteria at admission to the intensive care unit (ICU) and a second determination 24 hours later. DNA levels were determined by a PCR method using primers for the human beta-haemoglobin gene. RESULTS: One hundred and sixty consecutive patients were included: 43 SIRS without sepsis and 117 with sepsis. Levels of CRP and PCT, but not cf-DNA or eosinophil count, were significantly higher in patients with sepsis than in SIRS-no sepsis group on days 1 and 2. PCT on day 1 achieves the best area under the curve (AUC) for sepsis diagnosis (0.87; 95% confidence interval = 0.81-0.94). Levels of cf-DNA do not predict outcome and the accuracy of these biomarkers for mortality prediction was lower than that shown by APACHE II score. PCT decreases significantly from day 1 to day 2 in survivors in the entire cohort and in patients with sepsis without significant changes in the other biomarkers. CONCLUSIONS: Our data do not support the clinical utility of cf-DNA measurement in critical care patients with SIRS. PCT is of value especially for infection identification in patients with SIRS at admission to the ICU.

Analysis of antiretroviral therapy interruption in people living with HIV during the 2010-2021 period.

INTRODUCTION: In the context of the advancement of antiretroviral therapy and as the characteristics of people living with HIV progress toward an ageing population, understanding the causes of treatment interruption becomes crucial. The aim of the study was to determine the change in reasons for antiretroviral treatment discontinuation for 12 years. Secondarily, compare annual antiretroviral regimen discontinuation rate and factors associated. METHODS: We conducted an analysis using data from people living with HIV who were receiving antiretroviral therapy and discontinued it for any reason. The study included people with HIV infection who visited an outpatient hospital pharmacy clinic from January 2010 to December 2021. Two periods were differentiated for the analysis: 2010-2015 and 2016-2021. The reasons for antiretroviral treatment discontinuation followed classification described by Swiss cohort. In the context of this study, it is pertinent to note that the term "discontinuation" is employed synonymously with "interruption". The term "discontinuation" will be consistently used in this article to refer to the act of switching or stopping antiretroviral treatment. To examine factors associated with antiretroviral therapy discontinuation, we utilised Kaplan-Meier methods and Cox proportional models. RESULTS: We included 789 people living with HIV, predominantly male (81.5%). The main reason for discontinuation was clinical decision (50.2%) followed by adverse effects (37.9%). Focusing on clinical decision, we observed a trend change that went from antiretroviral treatment simplification regimen (56.1%) in the first part of the period analysed to the therapeutic optimisation (53.6%) in the second half. Furthermore, factors that were statistically significantly associated with antiretroviral treatment discontinuation were people with HIV≥50 years (HR 1.60; 95%CI 1.25-2.04), post-discontinuation single-tablet regimen (HR 1.49; 95%CI 1.06-2.11) and antiretroviral drug classes. CONCLUSION: Over the 12 years, there has been a change in the main cause of antiretroviral treatment discontinuation, currently therapeutic optimisation being the main reason. Integrase inhibitors-based regimens and single-tablet regimen strategies were less likely to be discontinued than others antiretroviral drug classes, allowing for better clinical management due to the efficacy profile, especially in people living with HIV≥50 years with comorbidities.

Clinical efficacy and safety of the combination of colistin plus vancomycin for the treatment of severe infections caused by carbapenem-resistant Acinetobacter baumannii.

A potent synergy of a glycopeptide-colistin combination against Acinetobacter baumannii has recently been described. We set out to assess the efficacy and safety of this combination in a retrospective study including episodes of ventilator-associated pneumonia or bacteremia caused by carbapenem-resistant A. baumannii. We compared 29 patients (group I) treated with colistin plus vancomycin with 28 patients treated with colistin alone (group II). Group I received vancomycin (for empirical or targeted therapy) at the onset of colistin administration and both antimicrobials coincided for at least 5 days. Baseline characteristics, clinical cure, microbiological eradication, and mortality were similar in both groups but the rate of acute kidney injury was higher in group I (55.2 vs. 28%; p = 0.04). In critically ill patients with carbapenem-resistant A. baumannii infections, clinical outcomes do not differ in patients treated with colistin plus vancomycin from those receiving colistin without vancomycin. This combination significantly increases the risk of renal failure.

Influence of polypharmacy in the simultaneous presence of high pharmacotherapeutic complexity, drug interactions and non-adherence to medication in patients with HIV infection. Project 3-HIT.

INTRODUCTION: The high pharmacotherapeutic complexity, drug interactions and lack of adherence to concomitant medication are circumstances with negative consequences in the clinical evolution of patients with HIV infection. The 3-HIT phenomenon refers to the simultaneous occurrence of these situations. The objective of the study is to determine the prevalence of the phenomenon 3-HIT in the polymedicated HIV population as well as to determine factors related to its occurrence. METHODS: Observational, retrospective and single-center study that included all elderly patients on active antiretroviral treatment in pharmacotherapeutic follow-up between January and March 2020. A logistic regression model was carried out to evaluate the factors associated with the occurrence of the 3-HIT concept with the variables significantly associated with this phenomenon and those considered clinically relevant. RESULTS: 428 patients were included, registering a prevalence of polypharmacy in 25.9% of the study sample. The 3-HIT phenomenon was detected in 6.3% of the patients. For each concomitant drug prescribed the risk of developing the phenomenon 3-HIT increases 1.5 times. CONCLUSION: Prevalence of the phenomenon 3-HIT is high in HIV patients with polymedication. A change in the pharmaceutical care model to a multidimensional setting is essential, together with pharmacotherapeutic optimization strategies to improve patient health outcomes.

Upraising Stenotrophomonas maltophilia in Critically Ill Patients: A New Enemy?

Stenotrophomonas maltophilia (S. maltophilia), an important pathogen in immuno-compromised patients, has recently gained attention in patients admitted in intensive care units (ICU). We sought to investigate clinical features of infections caused by S. maltophilia in ICU patients and identify risk factors for mortality. We conducted a retrospective study in two multivalent non-COVID-19 ICUs of tertiary-teaching hospitals in Greece and Spain, including patients with isolated S. maltophilia from at least one clinical specimen along with clinical signs of infection. A total of 103 patients (66% male) were analyzed. Median age was 65.5 (54-73.3) years and mean APACHE II and SOFA scores upon ICU admission were 18.36 (±7.22) and 18.17 (±6.95), respectively. Pneumonia was the predominant clinical syndrome (72.8%), while 22% of cases were among hemato/oncology patients. Crude 28-day mortality rate was 54.8%, even though, 14-day clinical and microbiological response was 96%. Age, APACHE II on ICU admission, hemato-oncologic disease, and multi-organ failure were initially identified as potential predictors of mortality. In the multivariable analysis, only increasing age and hemato-oncologic disease were shown to be independent risk factors for 28-day mortality. High all-cause mortality was observed in critically ill patients with predominantly respiratory infections by S. maltophilia, despite initial clinical and laboratory response after targeted treatment. The study elucidates a potentially worrisome emerging pathogen in the ICU.

[Characterization of hospitalized patients with acute kidney injury associated with COVID-19 in Spain: Renal replacement therapy and mortality. FRA-COVID SEN Registry Data]. / Caracterización de la población con fracaso renal agudo durante la hospitalización por COVID-19 en España: tratamiento renal sustitutivo y mortalidad. Datos del Registro FRA-COVID SEN.

Background and objectives: Acute kidney injury (AKI) is common among hospitalized patients with COVID-19 and associated with worse prognosis. The Spanish Society of Nephrology created the AKI-COVID Registry to characterize the population admitted for COVID-19 that developed AKI in Spanish hospitals. The need of renal replacement therapy (RRT) therapeutic modalities, and mortality in these patients were assessed. Material and method: In a retrospective study, we analyzed data from the AKI-COVID Registry, which included patients hospitalized in 30 Spanish hospitals from May 2020 to November 2021. Clinical and demographic variables, factors related to the severity of COVID-19 and AKI, and survival data were recorded. A multivariate regression analysis was performed to study factors related to RRT and mortality. Results: Data from 730 patients were recorded. A total of 71.9% were men, with a mean age of 70 years (60-78), 70.1% were hypertensive, 32.9% diabetic, 33.3% with cardiovascular disease and 23.9% had some degree of chronic kidney disease (CKD). Pneumonia was diagnosed in 94.6%, requiring ventilatory support in 54.2% and admission to the ICU in 44.1% of cases.The median time from the onset of COVID-19 symptoms to the appearance of AKI (37.1% KDIGO I, 18.3% KDIGO II, 44.6% KDIGO III) was 6 days (4-10). A total of 235 (33.9%) patients required RRT: 155 patients with continuous renal replacement therapy, 89 alternate-day dialysis, 36 daily dialysis, 24 extended hemodialysis and 17 patients with hemodiafiltration. Smoking habit (OR 3.41), ventilatory support (OR 20.2), maximum creatinine value (OR 2.41) and time to AKI onset (OR 1.13) were predictors of the need for RRT; age was a protective factor (0.95). The group without RRT was characterized by older age, less severe AKI, shorter kidney injury onset and recovery time (p < 0.05). 38.6% of patients died during hospitalization; serious AKI and RRT were more frequent in the death group. In the multivariate analysis, age (OR 1.03), previous chronic kidney disease (OR 2.21), development of pneumonia (OR 2.89), ventilatory support (OR 3.34) and RRT (OR 2.28) were predictors of mortality while chronic treatment with ARBs was identified as a protective factor (OR 0.55). Conclusions: Patients with AKI during hospitalization for COVID-19 had a high mean age, comorbidities and severe infection. We defined two different clinical patterns: an AKI of early onset, in older patients that resolves in a few days without the need for RRT; and another more severe pattern, with greater need for RRT, and late onset, which was related to greater severity of the infectious disease. The severity of the infection, age and the presence of CKD prior to admission were identified as risk factors for mortality in these patients. In addition chronic treatment with ARBs was identified as a protective factor for mortality.

Prevalence of compliance with PIMDINAC criteria among elderly people living with HIV and in non-infected outpatients with other chronic diseases.

BACKGROUND: There is a high prevalence of multimorbidity and polypharmacy among older people, especially in people living with HIV (PLWH) with an increased life expectancy due to effective antiretroviral therapy (ART). Consequently, there is a higher risk of potentially inappropriate medications (PIM), potential drug-drug interactions (DI), and problems of non-adherence to treatment (NAC) in older PLWH. PIMDINAC criteria (potentially inappropriate medications (PIM), drug-drug interactions (DI), and non-adherence to treatment (NAC)) purport to jointly analyse these problems. The purpose of the study was to compare the prevalence of PIMDINAC criteria among elderly PLWH and non-infected patients with chronic diseases, and to determine whether HIV infection constitutes a predictor of the presence of PIMDINAC criteria, totally or partially. METHODS: A cross sectional study was conducted between February and June 2020. HIV positive patients aged ≥65 years were compared with a group of patients with chronic conditions attending the outpatient hospital pharmacy service. RESULTS: The study involved 140 patients: 47 HIV positive and 93 HIV negative, and mean age was 69 versus 73 years, respectively (p=0.062). The prevalence of total PIMDINAC criteria was similar between the groups (12.5 vs 10.8%, p=0.505). In relation to inappropriate medication, no differences were observed between groups (48.9 vs 55.9%, p=0434). Drug-drug interactions were higher in patients with chronic conditions (52.7 vs 25.5%, p=0.002) compared with non-adherence, which was higher in people with HIV (22.6 vs 65.6%, p<0.001). No differences in polypharmacy (≥6 and 11 drugs) rates were observed. CONCLUSIONS: PIMDINAC criteria were highly prevalent in older PLWH, similar to non-infected patients. HIV infection in older people was associated with a lower risk of drug-drug interactions. However, non-adherence was a risk factor compared with age matched controls. Deprescribing strategies, including a capability-motivation-opportunity pharmaceutical care model based intervention should be implemented in clinical routines.

Clinical impact of procalcitonin-based algorithms for duration of antibiotic treatment in critically ill adult patients with sepsis: a meta-analysis of randomized clinical trials.

BACKGROUND: Our objective was to assess the impact on mortality, antibacterial therapy duration, and length of stay of using PCT to guide antibiotic cessation in critically ill patients with sepsis or septic shock. RESEARCH DESIGN AND METHODS: A systematic literature search was performed in PubMed, Embase, ISI Web of Knowledge, BioMed Central, ScienceDirect and the Cochrane Central Register of Controlled Trials, of clinical trials published in English before December 31, 2019. Eligible studies should be carried out in adults at ICU with sepsis, comparing the PCT-guided antimicrobial therapy with standard of care. A random effects model was used. RESULTS: Twelve studies were eligible with a total of 4292 patients included. The combined relative risk for 28-day mortality was 0.89 (95% CI: 0.79; 0.99), for the duration of antimicrobial therapy was -1.98 days (95% CI: -2.76, -1.21) and for ICU- length of stay was-1.21 days (95% CI: -4.16, 1.74). CONCLUSIONS: In critically ill adults with sepsis, a procalcitonin-guided strategy is associated with a significant shorter duration of antimicrobial therapy. This reduction was associated with a significant decrease in mortality although the length of ICU stay was not affected.

Prevalence of PIMDINAC criteria and associated factors in elderly HIV patients.

INTRODUCTION: Aging of people living with HIV could be related to potentially inappropiate medication prescriptions, drugs interactions and lack of drugs adherence. PIMDINAC criteria seek to jointly analyze these problems. The objective of this study is to determine the prevalence of PIMDINAC criteria in an elderly HIV population. METHODS: Observational, cross-sectional, multicenter study that included patients older than 65 years in pharmacotherapeutic follow-up between February-April 2020. The main endpoint was the percentage of PIMDINAC criteria identified in the study population. RESULTS: Forty-seven patientes were included, identifying total PIMDINAC in 12.5%. Non-adherence to concomitant treatment was detected in 65.6% of patients, potentially inappropiate medication in 48.9% and drugs interactions in 25.2%. The number of concomitant drugs and polypharmacy were associated with a higher appearance of PIMDINAC criteria. CONCLUSION: The prevalence of PIMDINAC criteria in elderly HIV patients is high.

Impact and acceptance of pharmacist-led interventions during HIV care in a third-level hospital in Spain using the Capacity-Motivation-Opportunity pharmaceutical care model: the IRAFE study.

INTRODUCTION: In recent decades, HIV has become a chronic disease with which the HIV specialist pharmacist plays a fundamental role. The traditional pharmaceutical care model followed to date relied excessively on the medication, obviating the uniqueness of each patient. The purpose of this study was to determine the influence and acceptance of a Capacity-Motivation-Opportunity (CMO)-based structured pharmaceutical care (PC) intervention in a multidisciplinary team for improving healthcare results. METHODS: Prospective single-centre study of a structured health intervention with patients living with HIV who attended hospital between January 2017 and June 2018 for any cause. Pharmacotherapeutic follow-up was applied according to the CMO PC model based on three key elements, namely stratification, motivational interview and new technologies. To assess differences in the variables collected before and after the intervention, Student's t-test or Wilcoxon test, and McNemar's test were used for quantitative and dichotomous variables, respectively. RESULTS: A total of 349 patients were included, 76.1% of which were men. The acceptance of pharmacist intervention by both doctors and patients was high [336 (97.7%) and 321 (93.3%)] and the adherence rate to antiretroviral therapy before intervention was lower than that observed afterwards (85.6%±33.7% vs 96.4%±17.7%; p<0.001). No differences were found between median viral load pre- versus post-intervention [1175 (62.75-26 050) copies/mL vs 274 (76.75-5542) copies/mL], although the undetectability rate was recorded as higher after intervention compared with the previous period [294 (85.5%) vs 274 (79.7%); p<0.001]. CONCLUSIONS: Our results could help HIV pharmacy clinic specialists to recognise high-risk patients and to develop personalised follow-up care, thereby ensuring good adherence and response to treatments.
