Restorative Care01:19

Restorative Care

Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...
Healthcare Agencies II01:17

Healthcare Agencies II

There are various healthcare agencies in the United States—some of which are managed by religious institutions and others by different government branches.
Parish nursing is a growing specialty nursing profession that focuses on holistic healthcare, health promotion, and illness prevention. It blends professional nursing practice with a health ministry, focusing on health and healing within the context of a Christian community. Parish nurses serve as health educators, referral sources, and lay...
Drug Concentrations: Measurements01:23

Drug Concentrations: Measurements

Drug concentration is the quantity of a drug present in a biological sample. Measuring drug amounts in biological samples allows the clinician to understand how a drug is absorbed, distributed, metabolized, and excreted. Samples can be obtained through invasive or non-invasive methods. Invasive techniques involve surgical or parenteral interventions to gather blood, cerebrospinal fluid, or tissue biopsy. Conversely, non-invasive approaches provide samples like urine, feces, and saliva.

Therapeutic Drug Monitoring: Affecting Factors01:29

Therapeutic Drug Monitoring: Affecting Factors

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: Drug Analysis Methods01:26

Therapeutic Drug Monitoring: Drug Analysis Methods

Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...
Community Based Intervention01:30

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.
Foundations of Community Mental Health Programs
Central to the success of community-based interventions is the...

Area of Science:

  • Public Health
  • Substance Use Research
  • Harm Reduction

Background:

  • Boston implemented harm reduction housing (HRH) to increase housing options and reduce overdose risk.
  • HRH residents lack access to drug checking services, despite potential benefits for identifying adulterants and monitoring supply shifts.
  • A pilot study integrated real-time drug checking into HRH sites, leveraging the Massachusetts Drug Supply Data Stream.

Purpose of the Study:

  • To pilot real-time, on-site drug checking services within harm reduction housing (HRH) programs in Boston.
  • To assess resident engagement and the utility of drug checking in identifying drug supply changes and informing harm reduction strategies.
  • To explore the role of drug checking in complementing existing harm reduction services in transitional housing.

Main Methods:

  • Administered surveys to 106 HRH residents and conducted longitudinal interviews with 28 participants.
  • Implemented real-time drug checking using FTIR spectroscopy and immunoassay test strips at three HRH sites.
  • Analyzed survey data, interview transcripts, and field notes to evaluate service provision and resident experiences.

Main Results:

  • Fifty-five drug samples were collected across nine site visits over three months, indicating considerable resident engagement.
  • Drug checking services increased xylazine awareness and provided opportunities to discuss concerns about the evolving drug market.
  • Residents confirmed the need for on-site drug checking, expressing consensus on concerns regarding the local drug supply.

Conclusions:

  • Real-time, on-site drug checking is a promising harm reduction strategy for low-barrier housing programs.
  • This approach effectively detects shifts in the drug supply and complements transitional housing interventions.
  • Residents utilize drug checking services to influence personal, community, and market-level norms regarding substance use.
