Prevalence of Gabapentinoids and Central Nervous System Depressant Drugs, and Their Association with Risk Factors for Respiratory Depression in Primary Care Patients.

BACKGROUND AND OBJECTIVES: Warnings have been published regarding an increased risk of severe respiratory depression in patients receiving gabapentinoids either alone or in combination with opioids and/or anxiolytics/hypnotics, especially in individuals with a respiratory risk factor. The aim is to report the prevalence of the use of gabapentinoids alone and associated with central nervous system depressant drugs, and possible associated risk factors for respiratory depression, in order to identify the most fragile population and establish intervention strategies. METHODS: We performed a cross-sectional study using computerized prescription records from the northern area of Barcelona at Catalan Institute of Health for 363,007 inhabitants registered during 2021. Patients aged ≥ 18 years with one or more gabapentinoid prescription were included. Age, gender, polypharmacy, adjusted morbidity groups, quantity of chronic diseases, and the number of consultations per year were independent variables. Four age categories were defined (18-64 years, then 64-74, 75-84, and those aged 85 years or older). Descriptive and inferential statistics were employed. Level of statistical significance was 5% (p ≤ 0.05). For the analysis, the SPSS program (version 22) was employed. RESULTS: Of the study sample, 9218 were prescribed gabapentidoids. Overall prevalence of use was 3.0% (women 3.6%, men 2.4%). On the whole, women used more drugs than men. In contrast to their younger counterparts, consumption increased 2.6 times, 3.8 times, and 4.0 times in the 65-74 age group, 75-84 age group, and those aged ≥ 85 years, respectively. Mean age was 65.59 (±15.80) years. Polypharmacy (5-9 drugs) was present in 41.7% of the patients and extreme polypharmacy (≥ 10 drugs) was present in 39.3% of the patients. Regarding renal function, 2396 patients (25.9%) had glomerular filtration that required dose adjustment (76.1% with gabapentin and 23.8% with pregabalin). In 141 patients (5.9%), a total daily dose higher than that authorized (109 with gabapentin, 29 with pregabalin) had been prescribed. The prescription of gabapentinoids combined with opioids and/or anxiolytics/hypnotics was significantly associated with (i) polypharmacy (5-9 drugs, OR: 3.42 [95% CI 3.00-3.88]; ≥ 10 drugs, OR 8.72 [95% CI 7.42-10.25]); (ii) quantity of chronic diseases, OR: 1.14 (95% CI 1.11-1.17); (iii) augmented number of consultations/year, OR: 1.01 (95% CI 1.00-1.01); (iv) female gender, OR: <  1 for men, OR: 0.66 (95% CI 0.60-0.73); (v) being elderly: 65-74 years, OR: 0.71 (95% CI 0.62-0.81); 75-84 years, OR: 0.62 (95% CI 0.54-0.71); ≥85 years, OR: 0.68 (95% CI 0.58-0.81); and (vi) adjusted morbidity groups, OR: 0.90 (95% CI 0.88-0.92), (p <  0.0001). CONCLUSION: Exposure to gabapentinoids occurs in a non-negligible percentage of the population. Greater numbers of combinations of gabapentinoids and opioids and/or anxiolytics/hypnotics were associated with polypharmacy, quantity of chronic diseases, and augmented number of consultations, but not with male gender, older age, and adjusted morbidity groups.

Tigecycline-associated hypofibrinogenemia in a real-world setting.

Background Tigecycline is a broad-spectrum antibiotic used to treat infections that do not respond to first-line treatments. High-doses and extended treatments are common; therefore, adverse events might be more frequent and severe than those observed in clinical trials. Several case-reports have referred hypofibrinogenemia in patients who received tigecycline. Objective To analyse the impact of tigecycline use on coagulation parameters, and identify which variables could be related with this. Setting The study was performed at Hospital Universitari Vall Hebron, in Barcelona, Spain. Method Observational, retrospective study. All patients older than 18, who received tigecycline for > 72 h from January 2016 to March 2018 were included. Clinical and laboratory data from before, during and at the end of tigecycline treatment were retrospectively collected. Differences between means were analyzed using the paired-sample Student's t-test. Binary logistic regression was performed to identify risk factors for hypofibrinogenemia. Main outcome measure Mean difference in fibrinogen plasma concentration and INR, before and at the end of tigecycline treatment. Results 78 patients (mean age 65; SD ± 15.5 years) were identified. The most common indications for tigecycline treatment were abdominal (66%), respiratory tract (16%) and skin&soft tissue (10%) infections. High-dose tigecycline was used in 62% of cases and the median duration of treatment was 12 days. Hypofibrinogenemia occurred in 12 patients, 5 bleeding events were observed and 4 of them required fibrinogen administration. Tigecycline caused significant alterations in fibrinogen plasma concentration (mean decrease 1.76 g/L; IC 95% 1.36 to 2.15) as well as INR (mean increase 0.11; IC 95% 0.05 to 0.17). Both were recovered after treatment cessation. We identified duration of treatment > 4 weeks (OR = 6.6), high-dose tigecycline (OR = 4.75) and high protein C levels (OR = 4.2) as independent variables associated with fibrinogen decrease, but not renal impairment. Conclusions Tigecycline administration has been related with hypofibrinogenemia, especially when high-doses of tigecycline are used. Health professionals should be aware of the potentially severe tigecycline-associated hypofibrinogenemia and monitor coagulation during treatment, especially when high-doses of tigecycline are used.

Efectividad de una intervención educativa multidisciplinar en pacientes con fractura de fémur: estudio SWEET HOME / Effectiveness of a multidisciplinary educational intervention in patients with hip fracture: SWEET HOME study

Antecedentes y objetivo: La fractura de fémur (FF) es una lesión frecuente en personas de edad avanzada. El objetivo fue evaluar la efectividad de una intervención educativa multidisciplinar en pacientes con FF para favorecer el regreso al domicilio y disminuir las complicaciones hospitalarias. Material y método: Estudio cuasiexperimental con medidas repetidas al ingreso, al alta, a los 30días y al año de seguimiento. Se incluyeron pacientes ≥65años con FF ingresados en la unidad de ortogeriatría entre febrero de 2016 y enero de 2017. La intervención educativa constó de dos actuaciones coordinadas: una educación sanitaria durante la hospitalización y un soporte multimodal durante la transición al domicilio. Resultados: Se incluyeron 67 pacientes (77,6% mujeres; edad 84,19±7,78 años). Regresaron al domicilio el 70,1%, doblando la cifra de los años 2014-2015. Hubo un 8,5% de reingresos a los 30días y al año. Al año, el nivel de dependencia fue cercano al nivel prefractura (Barthel: 86,67±19,31; 94,33±14,66), la movilidad mejoró respecto al alta (Parker: 4,73±1,84; 6,73±2,76; Timed Up and Go test: 38,29±21,27; 21,91±10,97) y el rendimiento cognitivo no empeoró de forma significativa. La percepción de pacientes, cuidadores y profesionales fue que la educación sanitaria mejoró la autonomía del paciente. La satisfacción con el proceso asistencial fue alta. Conclusiones: Este estudio aporta como novedad, a los beneficios ya descritos en los modelos asistenciales ortogeriátricos, el incremento del número de pacientes que regresan al domicilio en condiciones de seguridad

Background and objective: Hip fracture is a common injury among elderly patients. The main goal of our study was to assess the effectiveness of a multidisciplinary educational intervention aimed at hip fracture patients to promote home discharges and reduce in-hospital complications. Material and method: A quasi-experimental study was performed by taking repeated measurements at hospital admission, at hospital discharge, and at both 30days and one year of discharge. Patients aged ≥65years with hip fracture who were admitted to the Orthogeriatric Service between February 2016 and January 2017 were included in the study. The educational intervention consisted in two coordinated actions: patient education administered during their hospitalization and multimodal support provided during their discharge home. Results: A total of 67 patients were included in the study (77.6% of whom were women; 84.19±7,78 years old). Of these, 70.1% were discharged home, which doubles the figures recorded in the 2014-2015 period. The rate of readmission at 30days and one year of the discharge was 8.5%. At the one-year follow-up, the patient's dependence to perform basic activities of daily living was nearer to the pre-fracture level (Barthel: 86.67±19.31; 94.33±14.66), their mobility had improved in comparison with the time of discharge (Parker: 4.73±1.84; 6.73±2.76; Timed Up and Go Test: 38.29±21.27; 21.91±10.97), and their cognitive function had not worsened significantly. The patient education measures improved the patients' autonomy as perceived by the patients, the caregivers, and the healthcare providers. Satisfaction with the healthcare received was high. Conclusions: As a novelty to the already described benefits in orthogeriatric care models, this study would contribute by proving an increase of the number of patients discharged home in a safe condition
