Impact of a Pharmaceutical Care Program at Discharge on Patients at High Risk of Readmission According to the Hospital Score.

Background: A significant percentage of hospital readmissions within 30 days of discharge are a result of avoidable drug-related problems. Stratifying patients according to readmission risk is key to pharmaceutical intervention (PI) design strategies to improve treatment outcomes. Objective: To assess whether a pharmaceutical care (PC) program at discharge in polymedicated patients at high potentially avoidable readmission (PAR) risk, according to the HOSPITAL score, improves 30-day readmission rate (30-dRR). Methods: This prospective controlled, quasi-experimental, 11-month study included 163 chronic polymedicated patients (>5 medications) at high PAR risk according to the HOSPITAL score. We calculated the 30-dRR and number of medication variations and Medication Regimen Complexity Index-E (MRCI-E) after PI. Results were compared with a retrospective cohort of chronic patients at high PAR risk. Results: The 30-dRR was 18.4% in the intervention group and 25.6% in the control group (odds ratio [OR] = 0.66; 95% CI = 0.38 to 1.14). Total medication reduction (-1.28; 95% CI = -1.88 to -0.68), number of high-risk medications in chronic patients (-0.58; 95% CI = -0.9 to -0.26), and MRCI-E (-6.42; 95% CI = -8.07 to -4.76) were statistically significant (P < .001). The number of medications at discharge was associated with an increased readmission risk (OR = 1.07; 95% CI = 1.01 to 1.14). Conclusions: The degree of polypharmacy and patients' treatment complexity after hospital discharge significantly reduced as a result of the PC program compared with the control group. This highlights the need for patient selection and prioritization strategies for implementing PIs focused on reducing polypharmacy and preventing drug-related problems that may cause PAR.

[Translated article] Safety profile of nirmatrelvir-ritonavir: Evidence of adverse events due to DDIs.

OBJECTIVE: The aim of the study was to evaluate the safety profile of nirmatrelvir-ritonavir (NMV-r) in real clinical practice and to analyse the clinical relevance of drug-drug interactions in the development of adverse events. METHODS: Observational, retrospective study in which safety data of patients treated with NMV-r between April and July 2022 in an outpatient setting were evaluated. The duration of follow-up was 28 days and the number of adverse reactions reported, as well as whether they were managed on an outpatient basis or required health care, and the presence of renal and hepatic function impairment were assessed. Concomitant treatment was reviewed, identifying theoretical drug-drug interactions (TDDIs) whose severity was defined using the Lexi-interact classification. RESULTS: The study included 146 patients. 82 (56.16%) were women, whose median age was 65 years (22-95). the number of TDDIs detected and maintained during treatment with NMV-r was 164, with the percentage of patients with at least 1 interaction being 62.33%. The median number of TDDIs per patient was 1 (0-5). At least 1 adverse event (AE) was reported in 18 patients (11.84%). 11 AEs were potentially related to any TDDI. 7 patients required contact with hospital assistance for AE management. 8 patients had impaired renal function and 2 had impaired liver function at 28 days. The main groups of drugs implicated in the occurrence of an AE were oral anticoagulants and calcium antagonists. CONCLUSIONS: Our results show a high number of TDDIs detected were detected between NMV-r and other drugs. This study provides greater knowledge of the drugs involved in such interactions and their potential relationship with the occurrence of adverse events.

Influence of augmented renal clearance on the lower incidence of linezolid-related hematological toxicity. / Influencia de la hiperfiltración glomerular en la menor toxicidad hematológica inducida por linezolid.

OBJECTIVES: Linezolid is an oxazolidin commonly related to the development of hematological toxicity, being renal clearance the major factor involved in the drug clearance. The aim of this study is to evaluate the influence of increased filtration rates in the incidence of linezolid-induced hematological toxicity by comparing augmented renal clearance (ARC) patients versus normal renal function patients. MATERIAL AND METHODS: A retrospective, observational study was conducted on hospitalized patients treated with linezolid for 5 days or more during 2014-2019 period. Patients with a filtration rate of ≥130 mL/min versus reference patients (60-90 mL/min) were compared. Hematological toxicity was defined as a decrease of 25% in platelets, of 25% in hemoglobin and/or 50% in neutrophils from baseline. Toxicity relevance was classified according to Common Terminology Criteria for Adverse Events v5. Incidence of hematological toxicity between groups was studied by chi-square and Fisher test. Furthermore, percentaje disminution of all three parameters was calculated and compared by Mann-Whitney test and treatment interruption and tranfusion requirements were registered. RESULTS: 30 ARC patients and 38 reference patients were included. Hematological toxicity was observed in 16.66% of ARC patients vs 44.74% of reference patients (p = 0.014); thrombocytopenia in 13.33% vs 36.84% (p = 0.051), anemia in 3.3% vs 10.52% (p = 0.374) and neutropenia in 10% vs 23.68% (p = 0.204). Median percentaje of platelets decrease in ARC patients was -10.36 (-193.33-62.03) vs 2.68 (-163.16-82.71) in reference patients (p = 0.333), while hemoglobin decrease was 2.50 (-12.12-25.93) vs 9.09 (-17.72-30.63) (p = 0.047) and neutrophils decrease was 9.14 (-73.91-76.47) vs 27.33 (-86.66-90.90) (p = 0.093). 10.5% of normal renal function patients reported at least one adverse event grade 3 or superior while 2.6% of them interrupted treatment and 5.2% had tranfusion requirements. No major events or interruptions were reported in ARC patients. CONCLUSION: Our findings suggest a lower incidence and clinical relevance of hematological toxicity in augmented renal clearance patients. Thrombocytopenia was the major event in both populations. This might be related to a lower exposure to the drug due to the higher clearance and likely lower therapeutic efficiency. These results suggest a potential benefit of therapeutic drug monitoring on high risk patients.

Use of oral antineoplastic in special situations in a third level hospital: real life results.

OBJECTIVE: To analyse the effectiveness and safety of oral antineoplastic drugs  (ANEOs) that are authorized in special situations in a third-level hospital and to  compare the results obtained with the clinical evidence used for this  authorization. METHOD: Descriptive observational and retrospective study. We included all  adult patients who started treatment with ANEO in special situations during the  year 2016. We collected demographic, treatment-related and clinical variables  (overall survival (OS), progression-free survival (PFS)). Adverse reactions and  detected interactions were collected. An unadjusted comparison was made  between the results of the available evidence and those of the study patients. RESULTS: 34 patients were treated, 50% were men, the median age was 58  years (38-80) and they presented ECOG 1 in 64.7%. Most of the treated  patients were diagnosed with advanced colorectal cancer, treated with  trifluridine-tipiracil, followed by palbociclib in breast cancer, obtaining results  similar to those of the evidence. The median PFS was 2.8 months (95% CI 0.8- 4.8) and the 8-month SG (95% CI 3.4-12.5) for all patients. 26% of patients  required dose reduction because of treatment toxicity. We found 13 interactions,  which affected 15 patients, only two of category X. CONCLUSIONS: The effectiveness of ANEO in special situations in our center is  similar to that of available evidence. The impact on survival is low and adverse  effects are common.

Objetivo: Analizar la efectividad y seguridad de los antineoplásicos orales  (ANEO) autorizados en situaciones especiales en un hospital de tercer nivel y  comparar los resultados obtenidos con los de la evidencia disponible empleada  para autorizar el uso de estos fármacos.Método: Estudio descriptivo observacional y retrospectivo. Se incluyeron todos  los pacientes adultos que iniciaron tratamiento con ANEO en situaciones  especiales durante el año 2016. Se recogieron variables demográficas,  relacionadas con el tratamiento, y clínicas (supervivencia global (SG),  supervivencia libre de progresión (SLP)). Se recogieron reacciones adversas e  interacciones detectadas. Se realizó una comparación no ajustada entre los  resultados de la evidencia disponible y los de los pacientes del estudio.Resultados: Treinta y cuatro pacientes recibieron tratamiento, el 50% eran  hombres, la mediana de edad fue de 58 años (38-80), y presentaron ECOG 1 el  64,7%. La mayoría de los pacientes tratados presentaban diagnóstico de cáncer colorrectal avanzado, tratados con trifluridina-tipiracil, seguidos de  palbociclib en cáncer de mama, obteniendo resultados similares a los de la evidencia. La mediana de SLP fue de 2,8 meses (IC 95% 0,8-4,8) y la SG de 8  meses (IC 95% 3,4-12,5) para todos los pacientes. El 26% de los pacientes  requirieron una reducción de la dosis debido a la toxicidad del tratamiento. Se  encontraron 13 interacciones, que afectaron a 15 pacientes; solo dos de  categoría X.Conclusiones: La efectividad de los ANEO en situaciones especiales en nuestro  centro es similar al de la evidencia disponible.

Cerebrospinal fluid leak during stapes surgery: Gushing leaks and oozing leaks, two different phenomena.

Cerebrospinal fluid (CSF) leak is an uncommon event that can occur during stapes surgery. Such leaks can be classified as gushing leaks (stapes gushers) and oozing leaks. A stapes gusher is a massive flow of CSF through the perforated footplate that fills the middle ear suddenly, while an oozing leak is a slower and less profuse flow. We conducted a retrospective, observational, multicenter study of 38 patients-23 men and 15 women, aged 23 to 71 years (mean: 47)-who had experienced a CSF leak during stapes surgery. Patients were divided into various groups according to the type of surgical procedure performed and the type of postoperative complications they experienced. Audiometric and clinical evaluations were carried out pre- and postoperatively. Correlations among surgical variations (total or partial stapedectomy, placement of a prosthesis), hearing outcomes, and the incidence of postoperative complications (postoperative CSF leak and vertigo) were studied. Our statistical analysis revealed that gushing leaks and oozing leaks result in different degrees of hearing impairment and different rates of complications. We recommend that an individual approach be used to manage these complications.

[Effects of functional septoplasty in obstructive sleep apnea syndrome]. / Efectos de la septoplastia funcional en el síndrome de apnea obstructiva del sueño.

BACKGROUND AND OBJECTIVE: To evaluate the efficacy of functional septoplasty in a group of patients with septal dysmorphy and obstructive sleep apnea syndrome (OSAS). PATIENTS AND METHOD: 34 patients with nasal respiratory insufficiency and chronic snore were included from 1997 to 2003. All of them were diagnosed of OSAS by nocturnal polysomnography (PSG) and of septal dysmorphy by ORL physical examination. Patients were clinically followed-up at 1, 3 and 6 months after surgery. PSG was also evaluated at 6 months postsurgery. RESULTS: A significant objective reduction of the apnea-hypopnea index (AHI) (45.8 vs 31.9), severity of OSAS, and minimal mean oxygen saturation (76.4 to 83.1) was found. Moreover, we observed a significant improvement of subjective scales of sleepiness (13 vs 6) and the patients' satisfaction degree (72% of patients improved). CONCLUSIONS: Functional septoplasty is an effective treatment in patients with OSAS and septal dysmorphy.

Incidence and risk factors for tenofovir-associated renal toxicity in HIV-infected patients.

BACKGROUND: Since the beginning of highly active antiretroviral therapy utilization, the association of renal impairment with treatment toxicity is more prevalent. Tenofovir disoproxil fumarate (TDF) side effects include renal toxicity. OBJECTIVE: To assess the incidence of renal damage in human immunodeficiency virus (HIV)-positive patients treated with TDF and to identify associated potential risk factors. SETTING: A public university tertiary 450-beds hospital in Spain. METHOD: Retrospective, longitudinal observational study that included adult HIV-1-infected patients treated with TDF. Patient´s treated with TDF from January 2010 to December 2012 were included. Patient follow-up started when initiating treatment with TDF up until either end of treatment or end of study (July 31, 2013). The estimated glomerular filtration rate was calculated using the four-variable modification of diet in renal disease. Renal toxicity was classified as moderate [estimated glomerular filtration rate (eGFR) < 60 ml/min] or severe (eGFR < 30 ml/min). The incidence rate for moderate and severe renal insufficiency was calculated as number of cases per 1000 patient-year. A univariate analysis and binary logistic regression was carried out in order to identify risk factors associated with renal toxicity by using the forward stepwise method (likelihood ratio) MAIN OUTCOME MEASURE: Incidence rate for moderate and severe renal insufficiency (RI) RESULTS: 451 patients were included in the study. The incidence rate of moderate RI was 29.2 cases per 1000 person-year (95% CI 22.1-36.3), whereas the incidence of severe RI was 2.2 cases per 1000 person-year (95% CI 0.3-4.1). Multivariate analysis confirmed an independent association with the risk of kidney damage for age (OR 1.08 95% CI 1.05-1.12), time on treatment with TDF (OR 1.16 95% CI 1.04-1.30), baseline creatinine (OR 49.80 95% CI 7.90-311.92) and treatment with NNRTIs (OR 0.45 95% CI 0.24-0.83). CONCLUSION: Mild to moderate renal failure is a frequent complication during treatment with TDF although severe renal impairment is scarce. Risk factors include age, duration of treatment with TDF, elevated baseline creatinine levels, and treatment with protease inhibitor boosted with ritonavir combinations.

Se recogieron variables demográficas, relacionadas con el tratamiento, y clínicas (supervivencia global (SG), supervivencia libre de progresión (SLP)). Se recogieron reacciones adversas e interacciones detectadas. Se realizó una comparación no ajustada entre los resultados de la evidencia disponible y los de los pacientes del estudio. Resultados: Treinta y cuatro pacientes recibieron tratamiento, el 50% eran hombres, la mediana de edad fue de 58 años (38-80), y presentaron ECOG 1 el 64,7%. La mayoría de los pacientes tratados presentaban diagnóstico de cáncer colorrectal avanzado, tratados con trifluridina-tipiracil, seguidos de palbociclib en cáncer de mama, obteniendo resultados similares a los de la evidencia. La mediana de SLP fue de 2,8 meses (IC 95% 0,8-4,8) y la SG de 8 meses (IC 95% 3,4-12,5) para todos los pacientes. El 26% de los pacientes requirieron una reducción de la dosis debido a la toxicidad del tratamiento. Se encontraron 13 interacciones, que afectaron a 15 pacientes; solo dos de categoría X. Conclusiones: La efectividad de los ANEO en situaciones especiales en nuestro centro es similar al de la evidencia disponible. El impacto en la supervivencia es bajo y los efectos adversos son comunes (AU)

Objective: To analyse the effectiveness and safety of oral antineoplastic drugs (ANEOs) that are authorized in special situations in a third-level hospital and to compare the results obtained with the clinical evidence used for this authorization. Method: Descriptive observational and retrospective study. We included all adult patients who started treatment with ANEO in special situations during the year 2016. We collected demographic, treatment-related and clinical variables (overall survival (OS), progression-free survival (PFS)). Adverse reactions and detected interactions were collected. An unadjusted comparison was made between the results of the available evidence and those of the study patients. Results: 34 patients were treated, 50% were men, the median age was 58 years (38-80) and they presented ECOG 1 in 64.7%. Most of the treated patients were diagnosed with advanced colorectal cancer, treated with trifluridine-tipiracil, followed by palbociclib in breast cancer, obtaining results similar to those of the evidence. The median PFS was 2.8 months (95% CI 0.8-4.8) and the 8-month SG (95% CI 3.4-12.5) for all patients. 26% of patients required dose reduction because of treatment toxicity. We found 13 interactions, which affected 15 patients, only two of category X. Conclusions: The effectiveness of ANEO in special situations in our center is similar to that of available evidence. The impact on survival is low and adverse effects are common (AU)

Efectos de la septoplastia funcional en el síndrome de apnea obstructiva del sueño / Effects of functional septoplasty in obstructive sleep apnea syndrome

Fundamento y objetivo: Evaluar el efecto de la septoplastia funcional en un grupo de pacientes con dismorfia septal y síndrome de apnea obstructiva del sueño (SAOS). Pacientes y método: Se estudió a 34 pacientes con insuficiencia respiratoria nasal y roncopatía crónica desde 1997 hasta 2003. Se confirmó el SAOS mediante estudio polisomnográfico nocturno y la dismorfia septal por exploración otorrinolaringológica. Se estudió la evolución de los pacientes clínicamente a 1, 3 y 6 meses y con polisomnografía a los 6 meses. Resultados: Se evidenció una mejoría objetiva estadísticamente significativa en el índice de apnea-hipoapnea (pasó de 45,8 a 31,9; p ¾ 0,05), en la gravedad del SAOS (un 41,2% de los pacientes pasaron a leves o dejaron de tener SAOS), en la saturación arterial de oxígeno mínima media (del 76,4 al 83,1%), así como una mejoría subjetiva en la escala de Epworth (13 puntos comparado con 6) para la valoración de la somnolencia y del grado de satisfacción clínica de los pacientes (el 72% de los pacientes evidenciaron mejoría). Conclusiones: La septoplastia funcional es un tratamiento efectivo en pacientes con SAOS y dismorfia septal

Background and objective: To evaluate the efficacy of functional septoplasty in a group of patients with septal dysmorphy and obstructive sleep apnea syndrome (OSAS) Patients and method: 34 patients with nasal respiratory insufficiency and chronic snore were included from 1997 to 2003. All of them were diagnosed of OSAS by nocturnal polysomnography (PSG) and of septal dysmorphy by ORL physical examination. Patients were clinically followed-up at 1, 3 and 6 months after surgery. PSG was also evaluated at 6 months postsurgery. Results: A significant objective reduction of the apnea-hypopnea index (AHI) (45.8 vs 31.9), severity of OSAS, and minimal mean oxygen saturation (76.4 to 83.1) was found. Moreover, we observed a significant improvement of subjective scales of sleepiness (13 vs 6) and the patients' satistaction degree (72% of patients improved). Conclusions: Funtcional septoplasty is an effective treatment in patients with OSAS and septal dysmorphy
