Summary
A brief self-administered scale showed a modest ability to predict medication-related problems (MRPs). This tool may help identify patients for medication therapy management (MTM) services, complementing existing criteria.
Area of Science:
- Pharmacy Practice
- Clinical Pharmacy
- Health Services Research
Background:
- Medication Therapy Management (MTM) services are crucial for preventing and resolving medication-related problems (MRPs).
- Identifying patients most at risk for MRPs is a significant challenge in clinical practice.
- Self-administered scales offer a practical approach for patient screening in MTM.
Purpose of the Study:
- To evaluate the psychometric properties of a brief, self-administered scale designed to screen for MRPs.
- To assess the scale's reliability, construct validity, and criterion-related validity.
Main Methods:
- A two-phase, non-randomized, cross-sectional study involving community pharmacy and outpatient clinic patients.
- Phase 1: Item selection from a 78-item questionnaire (n=394).
- Phase 2: Validation of a nine-item scale (n=200) against pharmacist-identified MRPs during comprehensive medication reviews.
Main Results:
- Higher scores on the self-administered scale were positively correlated with an increased number of pharmacist-identified MRPs (r=0.24, P=0.001).
- Scale scores remained a significant predictor of MRPs in a multivariate regression model (P=0.031).
Conclusions:
- The self-administered scale demonstrates a modest capacity to predict medication-related problems.
- This screening tool may augment existing patient data for MTM eligibility criteria.
- Further research is recommended to fully establish the scale's utility.

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

2.0K
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

Pharmacodynamic methods provide insights into a drug's effects on physiological processes over time and play a crucial role in understanding bioavailability and therapeutic efficacy. These methods can be broadly classified into acute pharmacological and therapeutic response approaches, each with distinct mechanisms and applications.The acute pharmacological response method directly correlates a drug's physiological effects, such as ECG or pupil diameter changes, to its time course in the body.

Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

01:29Therapeutic Drug Monitoring: Affecting Factors
403
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood at designated intervals to ensure the drug concentration stays within a therapeutic range. This monitoring is crucial for optimizing individual dosage regimens, enhancing therapeutic efficacy, and minimizing drug-related toxicity. TDM is vital for drugs with narrow therapeutic windows, significant variability in pharmacokinetics, and a clear correlation between plasma levels and...
