Pregnant and lactating people's strategies to mitigate the risk of cannabis consumption.

BACKGROUND: Multiple studies have demonstrated that pregnant and lactating people who use cannabis perceive a variety of benefits from that use, offering some explanation of why rates of use continue to increase. OBJECTIVES: The aim of this study was to explore pregnant and lactating people's perceptions of the risks of cannabis use and understand what steps, if any, they take to mitigate these risks. DESIGN: Qualitative description. METHODS: We analyzed semi-structured interviews with 52 Canadians who made the decision to start, stop, or continue using cannabis during pregnancy or lactation between 2019 and 2021. Data collection iterated with analysis. We used a conventional (inductive) approach to content analysis. RESULTS: Perception of risk was found to be an essential component of decision-making about cannabis use. We identified a cycle of "risk identification," "management," and "observation" of effects. First, the pregnant or lactating person assesses the risks and weighs them against the perceived benefits of cannabis use. Second, they take action to minimize risks, with some choosing abstinence. Others, often those who were using cannabis to manage symptoms, continued cannabis use but devised a variety of other risk mitigation strategies such as, decreasing the amount or frequency of their use, changing the form of cannabis, and strategically timing their use with caregiving responsibilities. The final stage of the cycle involves seeking information about whether or not the initial perceived risk has manifested after implementing mitigation strategies, through observations and clinical information about the pregnancy or child. CONCLUSION: Participants consistently engaged in deliberation about the risks and benefits associated with their perinatal cannabis use. Nearly all implemented strategies intended to minimize risk. Our results highlight the need for more research to inform clear public health messaging about risk mitigation to minimize the potential harms of perinatal cannabis use. This work informs clinicians about patient-perceived risks and mitigation strategies which could in turn help inform shared decision-making conversations.

Black representation in critical care randomized controlled trials: a meta-epidemiological study.

PURPOSE: The under-representation of Black people within critical care research limits the generalizability of randomized controlled trials (RCTs). This meta-epidemiologic study investigated the proportionate representation of Black people enrolled at USA and Canadian study sites from high impact critical care RCTs. SOURCE: We searched for critical care RCTs published in general medicine and intensive care unit (ICU) journals between 1 January 2016 and 31 December 2020. We included RCTs that enrolled critically ill adults at USA or Canadian sites and provided race-based demographic data by study site. We compared study-based racial demographics with site-level city-based demographics and pooled representation of Black people across studies, cities, and centres using a random effects model. We used meta-regression to explore the impact of the following variables on Black representation in critical care RCTs: country, drug intervention, consent model, number of centres, funding, study site city, and year of publication. PRINCIPAL FINDINGS: We included 21 eligible RCTs. Of these, 17 enrolled at only USA sites, two at only Canadian sites, and two at both USA and Canadian sites. Black people were under-represented in critical care RCTs by 6% compared with population-based city demographics (95% confidence interval, 1 to 11). Using meta-regression, after controlling for pertinent variables, the country of the study site was the only significant source of heterogeneity (P = 0.02). CONCLUSION: Black people are under-represented in critical care RCTs compared with site-level city-based demographics. Interventions are required to ensure adequate Black representation in critical care RCTs at both USA and Canadian study sites. Further research is needed to investigate the factors contributing to Black under-representation in critical care RCTs.

RéSUMé: OBJECTIF: La sous-représentation des personnes noires dans la recherche en soins intensifs limite la généralisabilité des études randomisées contrôlées (ERC). Cette étude méta-épidémiologique a examiné la représentation proportionnelle des personnes noires inscrites aux sites américains et canadiens d'ERC à fort impact réalisées en soins intensifs. SOURCES: Nous avons recherché des ERC en soins intensifs publiées dans des revues de médecine générale et de soins intensifs (USI) entre le 1er janvier 2016 et le 31 décembre 2020. Nous avons inclus des ERC qui ont recruté des adultes gravement malades dans des sites américains ou canadiens et fourni des données démographiques basées sur la race par site d'étude. Nous avons comparé les données démographiques raciales de chaque étude aux données démographiques de la ville du site d'étude et regroupé la représentation des personnes noires dans les études, les villes et les centres en utilisant un modèle à effets aléatoires. Nous avons utilisé la méta-régression pour explorer l'impact des variables suivantes sur la représentation des personnes noires dans les ERC en soins intensifs : pays, intervention médicamenteuse, modèle de consentement, nombre de centres, financement, ville du site d'étude et année de publication. CONSTATATIONS PRINCIPALES: Nous avons inclus 21 ERC éligibles. De ce nombre, 17 ont recruté des patient·es uniquement dans des sites américains, deux dans des sites canadiens seulement et deux aux États-Unis et au Canada. Les personnes noires étaient sous-représentées dans les ERC en soins intensifs de 6 % par rapport à la population démographique des villes (intervalle de confiance à 95 %, 1 à 11). En utilisant la méta-régression, après avoir tenu compte des variables pertinentes, le pays du site d'étude était la seule source significative d'hétérogénéité (P = 0,02). CONCLUSION: Les personnes noires sont sous-représentées dans les ERC en soins intensifs par rapport aux données démographiques des villes. Des interventions sont nécessaires pour assurer une représentation adéquate des personnes noires dans les ERC en soins intensifs dans les sites d'étude américains et canadiens. D'autres recherches sont nécessaires pour étudier les facteurs contribuant à la sous-représentation des personnes noires dans les ERC en soins intensifs.

Making informed choices about cannabis use during pregnancy and lactation: A qualitative study of information use.

BACKGROUND: Cannabis use during pregnancy and lactation continues to increase as some perceive cannabis to be helpful for symptom management and coping. As such, pregnant and lactating people are faced with challenging decisions, weighing benefits against the potential risks of cannabis use. To help clinicians facilitate informed choices, we explored the self-identified information needs of pregnant and lactating people who are deciding whether or not to use cannabis. We aimed to describe the modes and sources of their information-seeking and their satisfaction with the information they found. METHODS: We interviewed 52 people in Canada who made the decision to start, stop, or continue using cannabis during pregnancy and lactation. Participants were recruited from advertisements in prenatal clinics and on social media. We utilized an inductive approach to analysis focused on information used in decision-making about cannabis use, including the process of seeking and evaluating that information. RESULTS: Participants were deliberate in their search for information, most commonly seeking information on risks of use. Information sources were mainly online material or people in their social networks. Clinicians were not commonly described as a knowledgeable or supportive source of information. Overwhelmingly, participants described the information they found as insufficient and emphasized the need for more comprehensive and trustworthy sources of information. CONCLUSIONS: Participants identified distinct and unmet information needs associated with their decision to use cannabis. They described a desire for clear evidence about the impact of cannabis use, including information about how to balance the benefits they perceived from cannabis use with the risks of harm.

Pregnant People's Perspectives On Cannabis Use During Pregnancy: A Systematic Review and Integrative Mixed-Methods Research Synthesis.

INTRODUCTION: Rates of perinatal cannabis use are rising, despite clinical evidence about the potential for harm. Accordingly, pregnant and lactating people who perceive a benefit from cannabis use may have a difficult time making informed decisions about cannabis use. METHODS: We conducted a systematic review of mixed-methods research to synthesize existing knowledge on the perspectives of pregnant people and their partners about cannabis use in pregnancy. Six health and social science databases were searched up until May 30, 2021. There were no methodological, time, or geographic limits applied. We employed a convergent integrative approach to the inductive analysis of findings from all studies. RESULTS: We identified 26 studies describing views of 17,781 pregnant and postpartum people about cannabis use in pregnancy. No studies describing the views of partners were identified, and only one study specifically addressed the perspectives of lactating people. Comparative analysis revealed that whether cannabis was studied alone or grouped with other substances resulted in significant diversity in descriptions of participant decision-making priorities and perceptions of risks and benefits. Studies of cannabis alone demonstrated a complex decision-making process whereby perceived benefits are balanced against the available information about risk, which is often unclear and uncertain. Clear and helpful information was difficult to identify, and health care providers were not described as a helpful and trusted resource for decision-making. DISCUSSION: Decision-making about cannabis use is difficult for pregnant and lactating people who perceive a benefit from this use, although this decisional difficulty is seldom reflected in studies that examine cannabis as one of multiple substances that pregnant or lactating people may use. Our review suggests several approaches clinicians may take to encourage open and supportive conversations to facilitate informed decisions about cannabis use during the perinatal period.

Clinician responses to cannabis use during pregnancy and lactation: a systematic review and integrative mixed-methods research synthesis.

BACKGROUND: Perinatal cannabis use is increasing, and clinician counselling is an important aspect of reducing the potential harm of cannabis use during pregnancy and lactation. To understand current counselling practices, we conducted a systematic review and integrative mixed-methods synthesis to determine "how do perinatal clinicians respond to pregnant and lactating patients who use cannabis?" METHODS: We searched 6 databases up until 2021-05-31. Eligible studies described the attitudes, perceptions, or beliefs of perinatal clinician about cannabis use during pregnancy or lactation. Eligible clinicians were those whose practice particularly focusses on pregnant and postpartum patients. The search was not limited by study design, geography, or year. We used a convergent integrative analysis method to extract relevant findings for inductive analysis. RESULTS: Thirteen studies were included; describing perspectives of 1,366 clinicians in 4 countries. We found no unified approach to screening and counselling. Clinicians often cited insufficient evidence around the effects of perinatal cannabis use and lacked confidence in counselling about use. At times, this meant clinicians did not address cannabis use with patients. Most counselled for cessation and there was little recognition of the varied reasons that patients might use cannabis, and an over-reliance on counselling focussed on the legal implications of use. CONCLUSION: Current approaches to responding to cannabis use might result in inadequate counselling. Counselling may be improved through increased education and training, which would facilitate conversations to mitigate the potential harm of perinatal cannabis use while recognizing the benefits patients perceive.

Cannabis use during pregnancy and breastfeeding is common and understanding current physician counselling approaches is important to identify gaps and to make suggestions for practice. We conducted a systematic review of the literature to understand how physicians respond to pregnant or breastfeeding patients who use cannabis. We found 13 eligible articles in our review and our analysis showed that there was no common approach to screening and counselling patients. Physicians often described needing more training and education to support their confidence. Additionally, physicians often did not address the various medical reasons for which patients might use cannabis during pregnancy and breastfeeding. We suggest that counselling approaches may be improved through increased education and training. This could facilitate conversations to help mitigate the potential harm of cannabis use while recognizing the benefits patients perceive and thus establish strong patient­physician relationships.

Reasons for cannabis use during pregnancy and lactation: a qualitative study.

BACKGROUND: Cannabis use among pregnant and lactating people is increasing, despite clinical evidence showing that cannabis use may be associated with low birth weight and childhood developmental deficits. Our objective was to understand why pregnant and lactating people use cannabis and how these motivations change across perinatal stages. METHODS: Using qualitative, constructivist grounded theory methodology, we conducted telephone and virtual interviews with 52 individuals from across Canada. We selected participants using maximum variation and theoretical sampling. They were eligible if they had been pregnant or lactating within the past year and had decided to continue, cease or decrease their cannabis use during the perinatal period. RESULTS: We identified 3 categories of reasons that people use cannabis during pregnancy and lactation: sensation-seeking for fun and enjoyment; symptom management of chronic conditions and conditions related to pregnancy; and coping with the unpleasant, but nonpathologized, experiences of life. Before pregnancy, participants endorsed reasons for using cannabis in these 3 categories in similar proportions, with many offering multiple reasons for use. During pregnancy, reasons for use shifted primarily to symptom management. During lactation, reasons returned to resemble those expressed before pregnancy. INTERPRETATION: In this study, we showed that pregnant and lactating people use cannabis for many reasons, particularly for symptom management. Reasons for cannabis use changed across reproductive stages. The dynamic nature of the reasons for use across stages speaks to participant perception of benefits and risks, and perhaps a desire to cast cannabis use during pregnancy as therapeutic because of perceived stigma.
