The use of antibiotics is the most important modifiable risk factor for the development of microorganism resistance. A cross-sectional study of outpatients receiving antibiotic prescriptions registered in a population database in Colombia was conducted. The characteristics of the consumption in capital cities and small municipalities was studied and the AWaRe classification was used. AWaRe classifies antibiotics into three stewardship groups: Access, Watch and Reserve, to emphasize the importance of their optimal use and potential harms of antimicrobial resistance. A total of 182,397 patients were prescribed an antibiotic; the most common were penicillins (38.6%), cephalosporins (30.2%) and fluoroquinolones (10.9%). ‘Access’ antibiotics (86.4%) were the most frequently prescribed, followed by ‘Watch’ antibiotics (17.0%). Being 18 or older, being male, living in a municipality, having one or more comorbidities and urinary, respiratory or gastrointestinal disorders increased the probability of receiving ‘Watch’ or ‘Reserve’ antibiotics. Penicillin and urinary antiseptic prescriptions predominated in cities, while cephalosporin and fluoroquinolone prescriptions predominated in municipalities. This analysis showed that the goal set by the WHO Access of mainly using Access antibiotics is being met, although the high use of Watch antibiotics in municipalities should be carefully studied to determine if it is necessary to design specific campaigns to improve antibiotics use.

The burden of herpes zoster disease is significant worldwide, with millions affected and an increasing incidence. Increased age and immunosuppression due to disease or drugs have been related to its recurrence. The aim of this work was to determine the pharmacological management of herpes zoster and identify factors associated with recurrence, representing a longitudinal retrospective study identifying the pharmacological management of patients with herpes zoster and the factors related to the first recurrence using a population database. Follow-up was carried out for up to 2 years, and descriptive analysis and Cox proportional hazards regression were performed. A total of 2978 patients with herpes zoster were identified, with a median age of 58.9 years and 65.2% being women. The treatment mainly involved acyclovir (98.3%), acetaminophen (36.0%), and non-steroidal anti-inflammatory drugs (33.9%). A total of 2.3% of patients had a first recurrence. Corticosteroids were used in a greater proportion for recurrence than for the initial herpes episode (18.8% vs. 9.8%, respectively). Being female (HR:2.68;95%CI:1.39–5.17), age ≥60 years (HR:1.74;95%CI:1.02–2.96), having liver cirrhosis (HR:7.10;95%CI:1.69–29.80), and having hypothyroidism (HR:1.99;95%CI:1.16–3.40) were associated with greater probability of a first recurrence. The vast majority of patients were managed with acyclovir, and the use of acetaminophen or non-steroidal anti-inflammatory drugs for pain management was frequent. Several conditions were found that increased the probability of presenting a first recurrence of herpes zoster, such as age over 60 years, being a woman, suffering from hypothyroidism, and liver cirrhosis.

The objective of this cohort study was to determine the association between the use of tramadol in emergency departments and the later consumption of opioids at the outpatient level in a group of patients from Colombia. Based on a medication dispensation database, patients over 18 years of age treated in different clinics in Colombia who for the first time received tramadol, dipyrone, or a nonsteroidal anti-inflammatory drug (NSAID) in the emergency room between January and December 2018 were identified. Three mutually exclusive cohorts were created, and each patient was followed up for 12 months after the administration of the analgesic to identify new formulations of any opioid. A Cox proportional-hazards regression model was constructed to identify variables associated with receiving a new opioid. A total of 12,783 patients were identified: 6020 treated with dipyrone, 5309 treated with NSAIDs, and 1454 treated with tramadol. The mean age was 47.1 ± 20.4 years, and 61.6% were women. A total of 17.3% (n = 2207) of all patients received an opioid during follow-up. Those treated with tramadol received a new opioid with a higher frequency (n = 346, 23.8%) than the other cohorts (14.7% NSAIDs and 17.9% dipyrone, both ). In the tramadol group, using more than 10 mg of morphine equivalents was associated with a greater use of new opioids (HR:1.47, 95%CI:1.12–1.93). Patients treated with tramadol in emergency departments have a higher risk of opioid use at the one-year follow-up than those treated with NSAIDs or dipyrone.
