Pharmacists, like psychiatrists, have modified their practices amidst COVID-19 in order to guarantee care and support to their patients. Designated an essential frontline service, community pharmacists are facing a spectrum of challenges to surmount to ensure patient care continues. These include assisting in the prevention of infection, managing supply chains, preventing stockpiling and provision of evidence-based medical information. However, disasters like COVID-19 disproportionately affect poor and vulnerable populations, and patients with mental health conditions may be among the hardest hit. Pharmacist-level, system-level and regulatory responses have sought to minimise this impact, although there is likely to be a lasting impression on the profession, both good and bad. This article reviews the pandemic-related challenges and responses by pharmacists, as well as forming recommendation for areas of professional support and role expansion, particularly in the case of mental health.

Children in PICUs normally require analgesics and sedatives to maintain comfort, safety, and cooperation with interventions. α2-agonists (clonidine and dexmedetomidine) have been described as adjunctive (or alternative) sedative agents alongside opioids and benzodiazepines. This systematic review aimed to determine whether α2-agonists were effective in maintaining patients at a target sedation score over time compared with a comparator group. We also aimed to determine whether concurrent use of α2-agonists provided opioid-sparing effects. A systematic search was performed using the Cochrane Central Register of Controlled Trials, PubMed, EMBASE, CINAHL, and LILACS. We included randomized controlled trials of children in PICU treated with clonidine or dexmedetomidine for the indication of sedation. Two authors independently screened articles for inclusion. Six randomized controlled trials with sufficient data were identified and critically appraised. Three clonidine trials (two vs placebo and one vs midazolam) and three dexmedetomidine trials (two vs fentanyl, one vs midazolam) were included. Due to study heterogeneity it was not possible to pool studies. A narrative synthesis is provided. Reporting of study results using the outcome "time maintained at target sedation score' for clonidine or dexmedetomidine was poor. Only one trial compared clonidine with midazolam using a sedation score outcome. This study was underpowered to demonstrate equivalence to midazolam as a sedative. The adjunctive use of clonidine demonstrated significant decreases in opioid use in neonates but not in older groups. Clonidine dose was inconsistent between studies. Dexmedetomidine demonstrated an opioid-sparing effect in two small trials. Further studies, including dose-finding studies and studies with sedation score-based outcomes, are needed.

Although high rates of poor adherence/persistence have been documented in ADHD, there is limited research targeting the problem. This systematic review evaluated interventions to address poor adherence/persistence to ADHD pharmacotherapy, with the aim of guiding the development of future interventions. An extensive search was conducted from January 1980 until January 2021. Thirteen studies were identified involving interventions based on psychoeducation, behavioural therapy, combined psychoeducation/behavioural therapy, technology-based interventions, written informed consent and a nursing support line. All 13 studies (including five RCTs) reported improvement in adherence/persistence and five studies (including four RCTs) also reported improvement in ADHD symptomatology. Almost all studies involved interventions utilising some form of education. Three RCTs of psychoeducation alone were included, with two of the three studies reporting adherence benefits at three and 12 months respectively. The third RCT was terminated early due to poor recruitment. A behavioural intervention RCT reported improved adherence six months post intervention (but not at 12 months), although a substantial drop-out rate was observed. A final included RCT used a Smartphone Application and reported a short term increase in adherence. The authors of the studies in this review make salient attempts at improving adherence and provide insight for future intervention development. We believe future interventions should involve combinations of strategies, have a theoretical framework and target the most common reasons for non-adherence. Interventions should also be integratable into routine care and include patient input to maximise sustainability.
