Pharmacogenomic-based personalized medicine: Multistakeholder perspectives on implementational drivers and barriers in the Canadian healthcare system.

ABSTRACT: Pharmacogenomics (PGx)-based personalized medicine (PM) is increasingly utilized to guide treatment decisions for many drug-disease combinations. Notably, London Health Sciences Centre (LHSC) has pioneered a PGx program that has become a staple for London-based specialists. Although implementational studies have been conducted in other jurisdictions, the Canadian healthcare system is understudied. Herein, the multistakeholder perspectives on implementational drivers and barriers are elucidated. Using a mixed-method qualitative model, key stakeholders, and patients from LHSC's PGx-based PM clinic were interviewed and surveyed, respectively. Interview transcripts were thematically analyzed in a stepwise process of customer profiling, value mapping, and business model canvasing. Value for LHSC located specialist users of PGx was driven by the quick turnaround time, independence of the PGx clinic, and the quality of information. Engagement of external specialists was only limited by access and awareness, whereas other healthcare nonusers were limited by education and applicability. The major determinant of successful adoption at novel sites were institutional champions. Patients valued and approved of the service, expressed a general willingness to pay, but often traveled far to receive genotyping. This paper discusses the critical pillars of education, awareness, advocacy, and efficiency required to address implementation barriers to healthcare service innovation in Canada. Further adoption of PGx practices into Canadian hospitals is an important factor for advancing system-level changes in care delivery, patient experiences, and outcomes. The findings in this paper can help inform efforts to advance clinical PGx practices, but also the potential adoption and implementation of other innovative healthcare service solutions.

Project description:BackgroundAbusive and disrespectful treatment of women during childbirth is a critical global issue that threatens women's sexual rights and reproductive rights and access to quality maternal care. This phenomenon has been documented in Colombia. However, little emphasis has been placed on identifying the drivers of and potential interventions against disrespect and abuse against particularly vulnerable populations in the country, including internally displaced indigenous women.MethodsThis report is a sub-analysis of a larger project. Semi-structured interviews were conducted with indigenous (Embera) women with childbirth experience (n = 10), maternal healthcare workers (n = 6), and community stakeholders (n = 5) in Medellín, Colombia. Qualitative analysis techniques, consisting of inductive and deductive approaches, were used to identify and characterize the drivers of disrespect and abuse against indigenous women during childbirth and points for intervention. Existing frameworks were adapted to thematically organize drivers and potential solutions into four interrelated subsystems: individual and community factors, clinician factors, facility factors, and national health system factors.ResultsParticipants highlighted disrespect and abuse as stemming from (within the individual and community level) its normalization, lack of autonomy and empowerment among indigenous women, lacking antenatal care, (within the clinician level) prejudice, linguistic or cultural barriers to communication, lack of understanding of indigenous culture, medical culture and training, burnout and demoralization, (within the facility level) inadequate infrastructure, space, and human resources, and (within the national systems level) lack of clear policies and the devaluing of respectful maternity care. They called for interventions specific to these drivers, grounded in dignity and respect for indigenous culture.ConclusionThis paper expands upon the growing literature on global mistreatment during childbirth by highlighting drivers of mistreatment and identifying points for intervention in a previously unstudied population. Our data show that indigenous women are especially vulnerable to mistreatment due to cultural and linguistic barriers and prejudice. Broad and meaningful action is urgently needed to realize these women's rights to respectful maternity care. Interventions must be multifaceted and locally specific, taking into account the needs and wants of the women they serve.
