RESUMO

BACKGROUND: Early identification and treatment of mental illnesses is imperative for optimal patient outcomes. Pharmacists may play an important role in mental healthcare through the provision of screening services for mental illnesses. OBJECTIVE: (s): To systematically review the impact of pharmacist-led mental illness screening on clinical or patient-reported outcomes and identify and report any follow-up or referral systems used in pharmacist-led screening interventions for mental illnesses. METHODS: A systematic review was conducted by searching MEDLINE, CINAHL, Embase and APA PsycInfo via EBSCOhost from inception to 9 March 2023 to identify studies involving pharmacist-led screening interventions for mental illnesses. Data was collected on the mental illness in question, setting and population characteristics, screening tools used, clinical or patient-reported outcomes, and follow-up and referral systems reported. RESULTS: Twenty six studies were identified that related to screening for mental illnesses, such as depressive disorders and substance use disorders. There were a variety of study designs, including uncontrolled studies (n = 23), pre-post studies (n = 2) and randomised controlled trials (n = 1). Screening was conducted in different settings, with most studies conducted in community pharmacies (n = 21/26, 87.8 %) and focusing on depression screening (n = 12/26, 46.1 %). A range of follow-up and referral methods to other healthcare professionals were reported, including verbal (n = 3/26, 11.5 %), both written and verbal (n = 3/26, 11.5 %), communications via electronic health record (n = 2/26, 7.7 %) and written (n = 1/26, 3.8 %). CONCLUSIONS: Pharmacists provide screening for a variety of mental illnesses in different settings. Various referral methods and follow-up pathways may be utilised for post-screening patient care. However, current evidence is insufficient to establish improvements in early detection, treatment, or outcomes. Further large, well-designed studies are required to support the role of pharmacists in mental illness screening, provide evidence on the impact of pharmacist-led mental illness screening services and inform the most effective follow up and referral methods.

RESUMO

BACKGROUND: This study aimed to describe children at risk of prolonged temporary tube feeding and evaluate associations between tube feeding duration and child and health service variables. METHODS: A prospective medical hospital records audit was conducted between November 1, 2018, and November 30, 2019. Children at risk of prolonged temporary tube feeding were identified as having a tube feeding duration of >5 days. Information was collected on patient characteristics (eg, age) and service delivery provision (eg, tube exit plans). Data were collected from the pretube decision-making phase until tube removal (if applicable) or until 4 months after tube insertion. RESULTS: Descriptively, 211 at-risk children (median, 3.7 years; interquartile range [IQR], 0.4-7.7) differed from 283 not-at-risk children (median age, 0.9 years; IQR, 0.4-1.8) in terms of age, geographical location of residence, and tube exit planning. Medical diagnoses of neoplasms, congenital abnormalities, perinatal problems, and digestive system diseases in the at-risk group were individually associated with longer than average tube feeding duration, as were the primary reasons for tube feeding of nonorganic growth faltering and inadequate oral intake related to neoplasms. Yet, variables independently associated with greater odds of lengthier tube feeding durations were consultations with a dietitian, speech pathologist, or interdisciplinary feeding team. CONCLUSION: Children at risk of prolonged temporary tube feeding access interdisciplinary management because of their complexity. Identified descriptive differences between at-risk and not-at-risk children may be useful when selecting patients for tube exit planning and developing tube feeding management education programs for health professionals.

RESUMO

BACKGROUND: Psychotropic polypharmacy and high-dose prescribing may play a role in therapy, however, with associated risks. The aim of this study was to describe current prescribing practices and use of four psychotropic medication groups (antipsychotics, antidepressants, mood stabilisers and benzodiazepines), focusing on polypharmacy (across and within groups) and high-dose prescribing in adults experiencing severe and persistent mental illness (SPMI) in the Australian community. METHODS: 318 people taking psychotropic medication for SPMI had a medication review undertaken by a community pharmacist. Participants were recruited as part of an RCT from three Australian states/territories between September 2020-July 2021. All psychotropic medication and daily doses were recorded and reviewed for alignment with current clinical guidelines. Univariate and multiple logistic regression models investigated factors associated with antipsychotic, antidepressant, and mood stabiliser polypharmacy, and antipsychotic and antidepressant high-dose therapy. Variables included age, gender, geographic location, self- reported mental illness(es), hospital admission(s) in previous 6-months and prescriber type. RESULTS: 806 psychotropic medications were prescribed for the 318 participants. Mood stabiliser polypharmacy was recorded in 19.0% of participants prescribed mood stabilisers; antipsychotic polypharmacy in 18.4% of participants prescribed antipsychotics; antidepressant polypharmacy in 11.3% of those prescribed antidepressants; and three participants (5.1%) were prescribed two benzodiazepines concurrently. Almost 18.6% of the cohort was receiving high-dose treatment; 18 participants were prescribed high-dose antipsychotics and 39 high-dose antidepressants, with two participants prescribed both. Adjusted logistic regression for polypharmacy found male gender, psychiatrist as sole prescriber, or multiple prescribers, were associated with antipsychotic polypharmacy. The adjusted model for high-dose therapy found psychiatrist as sole prescriber was significantly associated with antipsychotic and antidepressant high-dose prescribing. CONCLUSION: Psychotropic polypharmacy was common in this community cohort experiencing SPMI. Whilst polypharmacy is not always inappropriate, it is a complex construct with potential benefits alongside potential risks. Benefits and harms need to be balanced however this practice is not supported by clear guidance to assist health practitioners. This study highlights the important need for regular medication reviews and strengthened communication between consumers and all healthcare professionals involved in community mental health care, to support safe and effective use of psychotropic medications.

RESUMO

Perinatal depression (PND) screening recommendations are made by national, state-based and professional organisations; however, there is disagreement regarding screening timing, provider responsible, screening setting, screening tool as well as the follow-up and referral pathways required post-screening. This systematic review aimed to identify, describe and compare PND screening recommendations from member countries of the Organisation for Economic Co-operation and Development (OECD). Publications were identified through systematically searching PubMed, Google and the Guidelines International Network (GIN). Recommendations regarding PND screening endorsement, timing, frequency, responsible provider, tools/assessments and follow-up and referral were extracted. Twenty-one publications, including guidelines, from five countries were included. Most made recommendations in support of PND screening using the Edinburgh Postnatal Depression Scale. Details differed regarding terminology used, as well as frequency of screening, follow-up mechanisms and referral pathways. A broad range of health providers were considered to be responsible for screening. This is the first review to identify and compare PND screening recommendations from OECD member countries; however, only online publications published in English, from five countries were included. Heterogeneity of publication types and inconsistency in definitions rendered quality assessment inappropriate. While most publications generally endorsed PND screening, there are exceptions and the associated details pertaining to the actual conduct of screening vary between and within countries. Developing clear, standardised recommendations based on current evidence is necessary to ensure clarity amongst healthcare providers and a comprehensive approach for the early detection of PND.

RESUMO

INTRODUCTION: Community pharmacists are among the most accessible healthcare providers. Community pharmacist-led screening may facilitate the early detection of illnesses/medical risk factors, optimizing health outcomes. However, it is important to assess the acceptability of screening services to ensure uptake by key stakeholders. The aim of this review was to explore the acceptability of community pharmacist-led screening by all stakeholders (i.e., patients, pharmacists, and other healthcare professionals) and identify the methods used to evaluate the acceptability of screening. METHODS: A systematic search was conducted in Embase, MEDLINE, International Pharmaceutical Abstracts, and Scopus in April 2020 since inception. Studies that explored the acceptability of pharmacist-led screening for any risk factor/medical condition(s) within community pharmacies were included. RESULTS: A total of 44 studies met the inclusion criteria. A total of 17 studies identified community pharmacies as appropriate screening locations. Seven studies reported that patients were comfortable with participating in pharmacist-led screening. Eight studies explored acceptability from the perspective of medical practitioners and other healthcare professionals, with 6 reporting high recommendation acceptance rates and/or acceptability of pharmacist-led screening. Barriers to pharmacist-led screening included time and privacy constraints, whereas adequate remuneration was considered an important enabler. DISCUSSION: Community pharmacist-led screening appears to be acceptable to patients, pharmacists, and other healthcare professionals. However, no uniform psychometrically sound measure of acceptability was used consistently across studies, rendering comparisons difficult and showing the need for future research exploring the psychometric properties of acceptability measures. Findings, including barriers and enablers to pharmacist-led screening, are important to consider when providing screening services in community pharmacies.

RESUMO

OBJECTIVES: To explore the scope of dental and oral health care (DOHC) provided by the pharmacy profession and associated outcomes, and attitudes of pharmacy staff and other key stakeholders about pharmacy involvement in this context. METHODS: A scoping review of full-text articles describing outcomes related to pharmacy staff/student involvement in, knowledge of or attitudes towards DOHC in any setting, and stakeholder perspectives was conducted. Articles written in English were searched for using PubMed, EMBASE, EBSCO, International Pharmaceutical Abstracts, Education Resources Information Centre, Web of Science, Google Scholar, and ProQuest for Dissertations and Theses. No date restrictions were used. Key outcomes were mapped: role and practice, knowledge and attitudes, and training and education. RESULTS: Seventy studies met the inclusion criteria: 49 were conducted in developed countries; 60 were quantitative in design; and 38 involved community pharmacy settings only. Pharmacists and pharmacy support staff commonly managed DOHC inquiries (n = 13), including the provision of advice and products with or without a further referral. Integrated pharmacist-led services in dental settings (n = 4) showed improved prescribing and quality use of medicines but low community pharmacy referrals were identified in studies involving mystery shoppers with potential oral cancer (n = 7). DOHC promotion programmes delivered by pharmacy staff and collaborations with dentists were limited. There was interest from the pharmacy profession for a role in DOHC; however, knowledge gaps were reported and needs for further training identified. Consumer participant DOHC outcomes were not reported. CONCLUSIONS: Community pharmacists and pharmacy staff were interested in an expanded role in DOHC; however, this scoping review identified lack of knowledge and sub-optimal practice as potential barriers. Research on development, implementation and evaluation of DOHC-related services and practice by pharmacy staff was scarce. Further evidence of consumer-related oral health outcomes and their perceptions of the role of pharmacy is needed.

RESUMO

OBJECTIVE: The aim of the review is to identify and describe the characteristics and associated outcomes of dental and oral health advice and support provided by members of the pharmacy profession. Research exploring the role, attitudes, and knowledge of pharmacists, pharmacy students, and support staff relating to dental and oral health care, as well as stakeholder perceptions, will also be examined. INTRODUCTION: With the increasing prevalence of dental and oral health disorders and resource constraints within health care systems, other avenues for oral health promotion and care provision are warranted. Pharmacists, as primary care professionals working across various practice settings, could play a significant role in promoting good oral health. Yet, there is limited insight about the role, attitudes, and knowledge of members of the pharmacy profession towards dental and oral health care, as well as what stakeholders, such as consumers and other health care professionals, think about their role in this context. INCLUSION CRITERIA: Any full-text publication that describes outcomes related to pharmacist, pharmacy assistant, or student involvement, knowledge, or attitudes towards dental or oral health care in any setting, and stakeholder perspectives of this role, will be included. Reviews, protocols, and commentaries will be excluded, as will studies specifically focused on smoking cessation or that do not describe the related health promotion activity. METHODS: Articles published in English will be sought from health and educational databases with no date restrictions, with additional references identified via snowballing using citations and reference lists. Data searching and screening processes will follow JBI methodology, involving two independent reviewers, and data extraction presented in a narrative form.

RESUMO

Perinatal depression (PND) screening is encouraged in healthcare settings. We aimed to develop and content validate a basic PND knowledge questionnaire for use among pharmacists and potentially other primary healthcare professionals (HCPs). A six-item questionnaire was developed. Twenty-five perinatal mental health experts were invited to participate in content validation by completing the questionnaire and assessing its content validity. A content validity index (CVI) score above 0.8 was indicative of content validity. Expert comments may inform items' deletion or revision. Between November 2016 and February 2017, ten experts participated. For five out of six items, the CVI score was 0.9 or 1.0. Two experts selected "I think none are correct" for one item regarding the onset of postpartum depression. Comments reflected the lack of consensus in the literature surrounding onset periods and prevalence rates and informed minor modifications to three of six questions and seven of 24 response options. The CVI for the questionnaire was 0.83.Content validation of a questionnaire measuring basic PND knowledge resulted in modifications. Comments about PND onset and prevalence indicated the need for consistency when defining and measuring these constructs. This questionnaire may be used among pharmacists and other HCPs.

RESUMO

The Massachusetts Youth Screening Instrument-version 2 (MAYSI-2) was developed to help identify mental health needs of young people admitted to youth detention centres. Only one study has applied the tool to a UK population and none have looked at young people who live in residential and secure care in Scotland. This study aimed to assess the validity of the MAYSI-2 in Scotland with a looked after and accommodated population. Boys and girls in a large education and care centre were asked to complete the MAYSI-2 within 72 hours of being accommodated. A total of 168 males and 69 females with a mean age of 15 completed the tool. Substantial levels of mental health need were identified. Girls appeared to have higher needs on all areas, bar alcohol and substance misuse. The MAYSI-2 had good internal consistency and exploratory factor analysis showed good overlap with the tool's original factor model. As a result, there can be more confidence in the validity and consistency of the tool with this population. This is also further evidence of the high need of this population, particularly girls.

RESUMO

Prior to implementing perinatal depression (PND) screening, health-care professionals' acceptability of screening and their attitudes toward PND should be explored. We aimed to develop and psychometrically evaluate a questionnaire measuring PND attitudes and screening acceptability. A 31-item questionnaire was developed based on published questionnaires and a systematic review on PND screening acceptability. Principal components analysis with direct oblimin rotation was used to determine construct validity. Reliability of the resulting components was explored using Cronbach's α. Pharmacists (N = 153) were recruited from the Australian Association of Consultant Pharmacy. The scree plot and parallel analysis indicated a six-component solution. Due to cross-loadings (<.2 difference) and low loadings (<.445), it was necessary to delete 7 items. The six components explored PND screening acceptability, screening readiness, stigma, attitudes toward treatment efficacy, medication counseling responsibility, and the effect PND has on others. The six components explained 59.8% of the variance. Item loadings ranged from .445 to .880. Cronbach's α for each component ranged from .45 to .86. The construct validity and internal consistency reliability of the PND attitudes and screening acceptability questionnaire have been explored. Future measurements of these constructs using uniform, psychometrically sound scales may facilitate comparisons across studies.

RESUMO

OBJECTIVE: Infliximab (IFX) has an established role in Crohn's disease (CD), with serum trough levels of IFX (TLI) increasingly used to optimise dosing. We report the utility of routine, proactive TLI in children on combination therapy with immunosuppression (IS) from a single paediatric centre. METHODS: This is a retrospective chart review of all children with CD receiving IFX therapy conducted betweenJanuary 2014-May 2017. Clinical phenotype, duration of therapy, TLI (µg/mL), drug antibodies, type of IS, biomarkers and changes in management were recorded. RESULTS: 60 children (8-17 years; median 14.1 years) had 206 TLIs recorded. 56/60 (93%) were on IS, with 5/60 (8%) developing antidrug antibodies (ADAs). 63/206 TLIs were recorded duringan episode of relapse (median 3.0 µg/mL) vs 143/206 TLIs recorded in remission (median 5.2 µg/mL). For children with TLI <3 µg/mL, 31/63 (49%) were in relapse vs 30/143 (21%) in remission. For children with TLI >7 µg/mL, 7/63 (11%) were in relapse vs 46/143 (32%) in remission. Change in management resulted from 43/206 (21%) TLIs in 31/60 (52%) children: 21 dose escalations, 12 de-escalations and 10 changed to adalimumab. Of 31 postinduction TLIs, 15/17 (88%) children with TLI >7 µg/mL achieved clinical and biochemical remission for the duration of therapy (median 14 months), while 4/5 (80%) children with TLI <3 µg/mL required early dose escalation. Combination therapy with thiopurines (TP) (median TLI 4.9 µg/mL) versus methotrexate (MTX) (median TLI 5.2 µg/mL) achieved comparable levels with no difference in relapse frequency. CONCLUSIONS: Routine, proactive TLIs guide optimal management in children with CD. Postinduction and during maintenance, levels <3 µg/mL were associated with relapse and levels >7 µg/mL with sustained remission. Combination IS with TP and MTX appears to offer comparable TLI and ADA rates.

RESUMO

BACKGROUND: Perinatal depression (PND) affects approximately 10-15% of women, worldwide. PND screening, using screening tools, has been undertaken by a broad range of healthcare professionals in different settings. Our objective was to explore the acceptability of PND screening and how acceptability was being assessed. METHODS: A systematic literature review of studies that explored the acceptability of PND screening was carried out throughout MEDLINE, PsycINFO, PubMed, CINAHL, Embase, Maternity and Infant Care and Joanna Briggs Institute databases. RESULTS: Twenty-eight out of twenty-nine publications reported PND screening to be acceptable to most participants. A wide range of terms, questions and statements was used to infer, assess or report on acceptability. There was no uniform, psychometrically tested tool used to measure acceptability across the studies. LIMITATIONS: Broad inclusion criteria and methodological differences limited comparisons, but are overcome by the comprehensiveness of the data and the lack of uniformity across studies. CONCLUSIONS: Even though PND screening appears acceptable, it is difficult to draw conclusions about PND screening acceptability as studies used different methods to infer, assess or report on acceptability. The lack of a uniform, psychometrically tested tool to measure acceptability is not unique to PND. Nonetheless, the majority of perinatal women and healthcare professionals reported positive attitudes towards PND screening using different tools in different settings, indicating that it may be the responsibility of all healthcare professionals who come into contact with perinatal women.

RESUMO

Medicines are a major treatment modality for many mental illnesses, and with the growing burden of mental disorders worldwide pharmacists are ideally positioned to play a greater role in supporting people with a mental illness. This narrative review aims to describe the evidence for pharmacist-delivered services in mental health care and address the barriers and facilitators to increasing the uptake of pharmacist services as part of the broader mental health care team. This narrative review is divided into three main sections: (1) the role of the pharmacist in mental health care in multidisciplinary teams and in supporting early detection of mental illness; (2) the pharmacists' role in supporting quality use of medicines in medication review, strategies to improve medication adherence and antipsychotic polypharmacy, and shared decision making; and (3) barriers and facilitators to the implementation of mental health pharmacy services with a focus on organizational culture and mental health stigma. In the first section, the review presents new roles for pharmacists within multidisciplinary teams, such as in case conferencing or collaborative drug therapy management; and new roles that would benefit from increased pharmacist involvement, such as the early detection of mental health conditions, development of care plans and follow up of people with mental health problems. The second section describes the impact of medication review services and other pharmacist-led interventions designed to reduce inappropriate use of psychotropic medicines and improve medication adherence. Other new potential roles discussed include the management of antipsychotic polypharmacy and involvement in patient-centered care. Finally, barriers related to pharmacists' attitudes, stigma and skills in the care of patients with mental health problems and barriers affecting pharmacist-physician collaboration are described, along with strategies to reduce mental health stigma.

RESUMO

BACKGROUND: It is well established that muscle strength and exercise capacity are impaired in adults with cystic fibrosis (CF). Numerous factors have been implicated in this process including nutritional factors, disuse, and corticosteroid use. It is also known that serum testosterone levels are frequently low in adolescent male patients with CF. As testosterone is known to have an effect on peripheral muscle, we aimed to assess the relationship among circulating androgen levels, muscle strength, and exercise capacity in adults with CF. METHODS: A prospective observational study was performed. Participants underwent maximal exercise testing and peripheral muscle strength assessment (quadriceps, shoulder flexion, handgrip, maximal inspiratory pressure, and maximal expiratory pressure). Venous blood samples were obtained for the measurement of total testosterone, sex hormone-binding globulin, and albumin. The free testosterone (FT) level was calculated. RESULTS: A total of 15 subjects completed the study. The patients who were studied had impaired muscle strength and exercise capacity but normal mean androgen levels. Quadriceps strength, SF, and peak oxygen uptake (Vo(2)max) were 40.1 +/- 9.4%, 59.3 +/- 20.3%, and 77.4 +/- 22.2% predicted, respectively. One patient had a low testosterone level, with low FT levels evident in two subjects. There was no correlation between testosterone or FT level with any of the muscle strengths calculated. Neither testosterone or FT level was correlated with exercise capacity or pulmonary function. CONCLUSIONS: Male CF patients with impaired skeletal muscle strength and exercise capacity have normal testosterone levels. Hypogonadism was rare in this group of adult men with CF. These findings would not support the role of testosterone in muscle dysfunction or impaired exercise capacity in CF patients.
