Both interventions led to significant reductions in long-term benzodiazepine use in patients without severe comorbidity. A structured intervention with a written individualised stepped-dose reduction is less time-consuming and as effective in primary care as a more complex intervention involving follow-up visits.
BackgroundPrimary care interventions that promote cessation of benzodiazepine (BZD) use in longterm users are effective at 1 year, but their efficacy at 3 years is uncertain.
ObjectiveTo investigate possible relationships between pre-existing medical conditions (including common comorbidities and chronic medications) and risk for suffering COVID-19 disease in middle-aged and older adults.DesignPopulation-based retrospective cohort study.SettingTwelve primary care centres (PCCs) in Tarragona (Spain).Participants79 083 people (77 676 community-dwelling and 1407 nursing-home residents), who were all individuals aged >50 years affiliated to the 12 participating PCCs.OutcomesBaseline cohort characteristics (age, sex, vaccinations, comorbidities and chronic medications) were established at study start (1st. March 2020) and primary outcome was time to COVID-19 confirmed by PCR among cohort members throughout the epidemic period (from 1st. March 2020 to 23rd. May 2020). Risk for suffering COVID-19 was evaluated by Cox regression, estimating multivariable HRs adjusted for age, sex, comorbidities and medications use.ResultsDuring the study period, 2324 cohort members were PCR-tested, with 1944 negative and 380 positive results, which means an incidence of 480.5 PCR-confirmed COVID-19 cases per 100 000 persons-period. Assessing the total study cohort, only age (HR 1.02; 95% CI 1.01 to 1.03; p=0.002), nursing-home residence (HR 21.83; 95% CI 16.66 to 28.61; p<0.001) and receiving diuretics (HR 1.35; 95% CI 1.04 to 1.76; p=0.026) appeared independently associated with increased risk. Smoking (HR 0.62; 95% CI 0.41 to 0.93; p=0.022), ACE inhibitors (HR 0.68; 95% CI 0.47 to 0.99; p=0.046) and antihistamine (HR 0.47; 95% CI 0.22 to 1.01; p=0.052) were associated with a lower risk. Among community-dwelling individuals, cancer (HR 1.52; 95% CI 1.03 to 2.24; p=0.035), chronic respiratory disease (HR 1.82; 95% CI 1.08 to 3.07; p=0.025) and cardiac disease (HR 1.53; 95% CI 1.06 to 2.19; p=0.021) emerged to be also associated with an increased risk. Receiving ACE inhibitors (HR 0.66; 95% CI 0.44 to 0.99; p=0.046) and influenza vaccination (HR 0.63; 95% CI 0.44 to 0.91; p=0.012) was associated with decreased risk.ConclusionAge, nursing-home residence and multiple comorbidities appear predisposing for COVID-19. Conversely, receiving ACE inhibitors, antihistamine and influenza vaccination could be protective, which should be closely investigated in further studies specifically focused on these concerns.
The use of some anti‐hypertensive drugs in the current COVID‐19 pandemic has become controversial. This study investigated possible relationships between anti‐hypertensive medications use and COVID‐19 infection risk in the ambulatory hypertensive population. This is a population‐based retrospective cohort study involving 34 936 hypertensive adults >50 years in Tarragona (Southern Catalonia, Spain) who were retrospectively followed through pandemic period (from 01/03/2020 to 30/04/2020). Two data sets including demographic/clinical characteristics (comorbidities and cardiovascular medications use) and laboratory PCR codes for COVID‐19 were linked to construct an anonymized research database. Cox regression was used to calculate multivariable hazard ratios (HRs) and estimate the risk of suffering COVID‐19 infection. Across study period, 205 PCR‐confirmed COVID‐19 cases were observed, which means an overall incidence of 586.8 cases per 100 000 persons‐period. In multivariable analyses, only age (HR: 1.03; 95% CI: 1.02‐1.05; P < .001) and nursing home residence (HR: 19.60; 95% CI: 13.80‐27.84; P < .001) appeared significantly associated with increased risk of COVID‐19. Considering anti‐hypertensive drugs, receiving diuretics (HR: 1.22; 95% CI: 0.90‐1.67; P = .205), calcium channel blockers (HR: 1.29; 95%CI: 0.91‐1.82; P = .148), beta‐blockers (HR: 0.97; 95% CI: 0.68‐1.37; P = .844), and angiotensin‐converting enzyme inhibitors (HR: 0.83; 95% CI: 0.61‐1.13; P = .238) did not significantly alter the risk of PCR‐confirmed COVID‐19, whereas receiving angiotensin II receptor blockers was associated with an almost statistically significant reduction risk (HR: 0.67; 95% CI: 0.44‐1.01; P = .054). In conclusion, our data support that receiving renin‐angiotensin‐aldosterone system inhibitors does not predispose for suffering COVID‐19 infection in ambulatory hypertensive people. Conversely, receiving angiotensin II receptor blockers could be related with a reduced risk.
BackgroundAlthough benzodiazepines are effective, long-term use is not recommended because of potential adverse effects; the risks of tolerance and dependence; and an increased risk of hip fractures, motor vehicle accidents, and memory impairment. The estimated prevalence of long-term benzodiazepine use in the general population is about 2,2 to 2,6%, is higher in women and increases steadily with age. Interventions performed by General Practitioners may help patients to discontinue long-term benzodiazepine use. We have designed a trial to evaluate the effectiveness and safety of two brief general practitioner-provided interventions, based on gradual dose reduction, and will compare the effectiveness of these interventions with that of routine clinical practice.Methods/DesignIn a three-arm cluster randomized controlled trial, general practitioners will be randomly allocated to: a) a group in which the first patient visit will feature a structured interview, followed by visits every 2-3 weeks to the end of dose reduction; b) a group in which the first patient visit will feature a structured interview plus delivery of written instructions to self-reduce benzodiazepine dose, or c) routine care. Using a computerized pharmaceutical prescription database, 495 patients, aged 18-80 years, taking benzodiazepine for at least 6 months, will be recruited in primary care health districts of three regions of Spain (the Balearic Islands, Catalonia, and Valencia). The primary outcome will be benzodiazepine use at 12 months. The secondary outcomes will include measurements of anxiety and depression symptoms, benzodiazepine dependence, quality of sleep, and alcohol consumption.DiscussionAlthough some interventions have been shown to be effective in reducing benzodiazepine consumption by long-term users, the clinical relevance of such interventions is limited by their complexity. This randomized trial will compare the effectiveness and safety of two complex stepped care interventions with that of routine care in a study with sufficient statistical power to detect clinically relevant differences.Trial RegistrationCurrent Controlled Trials: ISRCTN13024375
BackgroundPneumococcal diseases remain a major cause of morbidity and mortality worldwide. Updated data on drug-resistance from different populations may be important to recognize changes in disease patterns. This study assessed current levels of penicilin resistance among Streptococcus Pneumoniae causing pneumonia in Spanish middle age and older adults.MethodsAntimicrobial susceptibility was tested for 104 consecutive isolates of Streptococcus pneumoniae recovered from patients 50 years or older with radiographically confirmed pneumonia in the region of Tarragona (Spain) between 2002 and 2007. According to the minimum inhibitory concentration of tested antimicrobials (penicillin, erythromycin, cefotaxime and levofloxacin) strains were classified as susceptible or resistant. Antimicrobial resistance was determined for early cases (2002–2004) and contemporary cases (2005–2007).ResultsTwenty-seven (25.9%) were penicillin-resistant strains (19 strains with intermediate resistance and 8 strains with high resistance). Penicillin-resistance was higher in 2002–2004 than in 2005–2007 (39.5% vs 18.2%, p = 0.017).Of 27 penicillin-resistant strains, 10 (37%) were resistant to erythromycin, 8 (29.6%) to cefotaxime, 2 (7.4%) to levofloxacin, and 4 (14.8%) were identified as multidrug resistant. Case-fatality rate was higher among those patients who had an infection caused by any penicillin susceptible strain (16.9%) than in those with infections due to penicillin-resistant strains.ConclusionResistance to penicillin among Streptococcus pneumoniae remains high, but such resistance does not result in increased mortality in patients with pneumococcal pneumonia.
Objetivo Analizar y comparar la epidemiologia de los incidentes de seguridad del paciente notificados en centros de atención primaria, antes y después del inicio de la pandemia COVID-19. Diseño y emplazamiento Estudio descriptivo analítico comparando los incidentes notificados del 01-marzo-2019 al 28-febrero-2020, y del 01-marzo-2020 al 28-febrero-2021, realizados a través de la plataforma TPSC Cloud™ accesible desde la Intranet corporativa en 25 centros de atención primaria del distrito de Tarragona, Cataluña, España. Mediciones Registros obtenidos a partir de notificaciones voluntarias mediante formulario electrónico, estandarizado y anonimizado. Variables: centro sanitario, profesional, tipo de incidente, matriz de riesgo, factores causales, contribuyentes y evitabilidad. Análisis estadístico: Se realizó análisis descriptivo del total de notificaciones y otro específico de los eventos adversos, comparando ambos períodos. Resultados Se notificaron un total de 2.231 incidentes. Comparando ambos períodos, en el de pandemia se observó una reducción del número de incidentes notificados (solo representaron un 20% del total), pero en proporción se incrementó el porcentaje de notificaciones por parte de profesionales sanitarios y el de eventos adversos que requirieron observación. También aumentaron los factores causales relacionados con los cuidados y el diagnóstico, y disminuyeron los de medicación. Además, se observó un incremento de los factores contribuyentes relacionados con el profesional. La evitabilidad fue elevada (>95%) en ambos períodos. Conclusiones Durante la pandemia, se han notificado un menor número de incidentes de seguridad del paciente, pero en proporción, más eventos adversos, siendo en su mayoría evitables. El propio profesional se convierte en el principal factor contribuyente.
IntroductionBenzodiazepines (BZDs) are mainly used to treat anxiety and sleep disorders, and are often prescribed for long durations, even though prescription guidelines recommend short-term use due to the risk of dependence, cognitive impairment, and falls and fractures. Education of general practitioners (GPs) regarding the prescription of BZDs may reduce the overuse and of these drugs.The aims of this study are to analyse the effectiveness of an intervention targeted to GPs to reduce BZD prescription and evaluate the implementation process.Methods and analysisThe healthcare centres in three regions of Spain (Balearic Islands, Catalonia and Community of Valencia) will be randomly allocated to receive a multifactorial intervention or usual care (control). GPs in the intervention group will receive a 2-hour workshop about best-practice regarding BZD prescription and BZD deprescribing, monthly feedback about their BZD prescribing practices and access to a support web page. Outcome measures for each GP are the defined daily dosage per 1000 inhabitants per day and the proportion of long-term BZD users at 12 months. Data will be collected from the electronic prescription database of the public health system, and will be subjected to intention-to-treat analysis. Implementation will be evaluated by mixed methods following the five domains of the Consolidated Framework For Implementation Research.Ethics and disseminationThis study was approved by the Balearic Islands Ethical Committee of Clinical Research (IB3065/15), l’IDIAP Jordi Gol Ethical Committee of Clinical Research (PI 15/0148) and Valencia Primary Care Ethical Committee of Clinical Research (P16/024). The results will be submitted for publication in peer-reviewed journals.Trial registration number ISRCTN28272199.
