Prescription of transdermal patches in Colombia: A real-world evidence study.

BACKGROUND: Transdermal drug delivery has contributed positively to medical practice. However, prescriptions that do not meet minimum quality criteria and medication errors are common. OBJECTIVE: The objective was to determine how transdermal patches are being prescribed to a group of patients in Colombia, the compliance with established requirements of such prescriptions and the comparisons between correct and incorrect prescriptions. METHODS: This was a cross-sectional study of prescriptions for transdermal patches using data from a population-based drug dispensing database between December 1 and 31, 2019. Medical prescriptions were randomly reviewed, establishing whether the drugs were appropriately prescribed by the manufacturer's indications or national regulations. Descriptive and bivariate analysis was performed. RESULTS: A total of 415 prescriptions were reviewed; the prescription was provided to 412 patients with a median age of 76.9 years, and 63.3% were women. Rivastigmine was the most prescribed transdermal patch (57.8%). 66.3% of all prescriptions did not meet the minimum appropriate prescribing standards, especially those for rivastigmine (97.1%). The 7.0% of all prescriptions had posology errors, especially prescriptions for buprenorphine (43.8%). Older patients (84.4% vs 52.5%), from the Pacific region (34.4% vs 23.7%), with manual formulations (22.1% vs 0.8%), dementia (49.0% vs 6.8%), and in management with lipid-lowering drugs (41.8% vs 30.5%), presented incorrect transdermal patch formulations more frequently (p < 0.05). CONCLUSION: The high proportion of inappropriately prescribed transdermal patches should draw the attention of those responsible for health care to improve the training of physicians and create prescription quality verification systems.

Indication-prescription study for the management of conjunctivitis in a Colombian population.

PURPOSE: Conjunctivitis is one of the most common ocular pathologies. Its treatment depends on its etiology, but an excessive use of antibiotics and corticosteroids, which in many cases are contraindicated, has been described. The objective was to describe the prescription patterns of medications used to treat conjunctivitis in a Colombian population. METHODS: This was a cross-sectional study on the pharmacological treatment of patients diagnosed with conjunctivitis between April 1, 2020, and March 31, 2021; based on a drug-dispensing database of approximately 8.5 million people affiliated with the Colombian Health System. Some sociodemographic and pharmacological variables and comorbidities were considered. A descriptive analysis was performed. RESULTS: A total of 8708 patients were identified; they had a median age of 44.7 years, and 59.3% were women. The most common causes of conjunctivitis were unspecified (53.1%) and allergic (37.4%). The most commonly used drug was olopatadine (26.1%), followed by dexamethasone with neomycin and polymyxin B (25.0%). A total of 97.0% of the patients received ophthalmic prescriptions, while 12.8% received systemic medications. Glucocorticoids (40.3%), antibiotics (37.7%) and antihistamines (31.7%) were the most commonly used groups of ophthalmic drugs. Glucocorticoids and ophthalmic antibiotics were the medications most frequently prescribed by general practitioners for the treatment of viral or bacterial conjunctivitis. CONCLUSIONS: Many patients with conjunctivitis are not being managed according to the recommendations of clinical practice guidelines, which highlights that the widespread use of antibiotics with ophthalmic glucocorticoids could be considered potentially inappropriate prescriptions in many cases.

Study of Prescription-Indication of Outpatient Systemic Anti-Fungals in a Colombian Population. A Cross-Sectional Study.

The inappropriate use of antifungals is associated with greater antimicrobial resistance, costs, adverse events, and worse clinical outcomes. The aim of this study was to determine prescription patterns and approved and unapproved indications for systemic antifungals in a group of patients in Colombia. This was a cross-sectional study on indications for the use of systemic antifungals in outpatients from a drug dispensing database of approximately 9.2 million people affiliated with the Colombian Health System. Sociodemographic, pharmacological, and clinical variables were considered. Descriptive, bivariate, and multivariate analyses were performed. A total of 74,603 patients with antifungal prescriptions were identified; they had a median age of 36.0 years (interquartile range: 22.0−53.0 years), and 67.3% of patients were women. Fluconazole (66.5%) was the most prescribed antifungal for indications such as vaginitis, vulvitis, and vulvovaginitis (35.0%). A total of 29.3% of the prescriptions were used in unapproved indications. A total of 96.3% of ketoconazole users used the medication in unapproved indications. Men (OR: 1.91; CI95%: 1.79−2.04), <18 years of age (OR: 1.20; CI95%: 1.11−1.31), from the Caribbean region (OR: 1.26; CI95%: 1.18−1.34), with chronic obstructive pulmonary disease (OR: 1.80; CI95%: 1.27−2.54), prescriptions made by a general practitioner (OR: 1.17; CI95%: 1.04−1.31), receiving comedications (OR: 1.58; CI95%: 1.48−1.69), and the concomitant use of other antimicrobials (OR: 1.77; CI95%: 1.66−1.88) were associated with a higher probability that the antifungal was used for unapproved indications; deep mycosis (OR: 0.49; CI95%: 0.41−0.58), prescribing fluconazole (OR: 0.06; CI95%: 0.06−0.06), and having diabetes mellitus (OR: 0.33; CI95%: 0.29−0.37), cancer (OR: 0.13; CI95%: 0.11−0.16), or HIV (OR: 0.07; CI95%: 0.04−0.09) reduced this risk. Systemic antifungals were mostly used for the management of superficial mycoses, especially at the gynecological level. In addition, more than a quarter of patients received these medications in unapproved indications, and there was broad inappropriate use of ketoconazole.

Characterization of sexually transmitted infections, their pharmacological treatment, and recurrence in a Colombian population. / Caracterización de las infecciones de transmisión sexual, su tratamiento farmacológico y la recurrencia en una población colombiana

INTRODUCTION: Sexually transmitted infections are a public health problem worldwide. Their inadequate antimicrobial management has been associated with a higher risk of recurrence. OBJECTIVE: To characterize the main sexually transmitted infections, the adherence to clinical practice guidelines, and the factors associated with recurrence in Colombia. MATERIALS AND METHODS: We conducted an observational study to identify the main sexually transmitted infections, the sociodemographic variables, and the pharmacological management in a patient cohort from a population database of 6.5 million people affiliated with the Colombian health system. We made a multivariate analysis to identify the variables associated with recurrence. RESULTS: We detected 3,158 patients with a mean age of 41.8 ± 14.5 years, of whom 63.1% were men. We found 4.030 episodes of sexually transmitted infections, predominantly urethral syndrome (27.5%). Only 13.6% of patients with urethral syndrome, ulcerative syndrome, or genital warts were managed in compliance with clinical practice guidelines and 20.6% were dispensed condoms; 16.7% of patients had recurrences and being male (OR=1.32; 95%CI 1.08-1.63), <30 years old (OR=1.72; 95%CI 1.40-2.13), being treated in municipalities other than capital cities (OR=1.43; 95%CI 1.06-1.94), and having received inadequate treatment for the first episode (OR=1.93; 95%CI 1.52-2.39) were associated with recurrence. CONCLUSIONS: The majority of patients with sexually transmitted infections were not treated in compliance with clinical practice guidelines and those who did not have adequate management had a higher risk of recurrence.

Potentially Inappropriate Prescriptions of Antipsychotics for Patients With Dementia.

Dementias are neurodegenerative and progressive diseases of the central nervous system. The objective of this study was to determine the frequency of potentially inappropriate prescriptions of antipsychotics in a group of patients diagnosed with dementia in Colombia. This was a cross-sectional study based on a population database for drug dispensing that identified prescriptions of antidementia drugs, antipsychotics, and other drugs for patients with a diagnosis of dementia. Descriptive statistics and bivariate and multivariate analyses were performed. A total of 11,372 patients with dementia were identified; 66.6% were women, and the mean age was 80.5 ± 9.6 years. Alzheimer's disease was the most frequent diagnosis (76.6%). A total of 69.0% of patients received antidementia drugs. A total of 37.1% of patients received some antipsychotic, especially atypical antipsychotics (31.0%). Increased age, being treated with memantine, simultaneously presenting with anxiety, depression, and psychotic disorders, and concomitantly receiving anticonvulsants, bronchodilators and benzodiazepines were associated with a greater probability of being prescribed antipsychotics. More than one-third of patients with dementia received antipsychotic prescriptions, which are considered potentially inappropriate because they can worsen cognitive decline and favor the occurrence of adverse events.
