Advice given in community pharmacies to patients with possible oral carcinoma

A scoping review of pharmacy participation in dental and oral health care

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.

Investigating the management of potentially cancerous nonhealing mouth ulcers in Australian community pharmacies

We sought to examine the management and referral of nonhealing mouth ulcer presentations in Australian community pharmacies in the Greater Brisbane region. Trained simulated patients visited 220 randomly selected community pharmacies within the Greater Brisbane region in 2016. Simulated patients enacted two nonhealing (>1 month) mouth ulcer scenarios: A direct product request (DPR) (n = 110) and a symptom-based request (SBR) (n = 110). Results were documented and evaluated against Australian national pharmacy practice standards. Referral rates for pharmacy staff (pharmacist, pharmacy assistant or mixed-pharmacist and assistant) were also assessed. Australian pharmacy practice standards recommend staff ask six key questions during SBR and DPR consultations to enable informed decision-making. Two questions relating to identifying the patient and their symptoms were asked in the majority of interactions (76% and 69% respectively); the remaining four questions relating to symptom duration, treatments tried, other medications, and medical conditions were enquired in only 32%, 53%, 31%, and 27% of interactions, respectively. Simulated patients were referred to the doctor/dentist in only 11.8% of all interactions (both scenarios requiring referral). Overall, staff handling of nonhealing mouth ulcer consultations was suboptimal compared to national professional standards. In particular, duration of the nonhealing mouth ulcer was enquired in less than one-third of consultations potentially resulting in low referral rates by staff. This study identifies the need for increased oral cancer awareness and education for community pharmacy staff and reinforcing the importance of practising according to professional standards to effectively screen for potentially cancerous nonhealing mouth lesions.

A systematic review of community pharmacies' staff diagnostic assessment and performance in patient consultations

BACKGROUND

Increases in patients seeking advice at pharmacies has led to pharmacy staff engaging in diagnostic behaviours. Approaches to diagnosis include using mnemonics and clinical reasoning.

OBJECTIVES

The primary aim of this review was to assess the degree to which the criteria researchers use to evaluate diagnostic performance in pharmacy consultations, in studies that have simulated patients or vignettes, conform with a clinical reasoning and a mnemonic framework. A secondary aim of the review was to characterize staff performance in the studies, based on the authors' comments of their results.

METHODS

MEDLINE, EMBASE and Web of Science were searched between October 2016 and April 2017. Only peer-reviewed studies assessing pharmacy staff's diagnostic performance using simulated patients or vignettes were eligible for inclusion. Data were extracted about how each study's criteria conformed with clinical reasoning and mnemonic frameworks. A scoring system between 0 and 4 was devised to determine the degree to which studies aligned to these two approaches. Risk of bias was assessed using the NHI Study Quality Assessment Tools. The review was registered in PROSPERO with identification number CRD42017054827.

RESULTS

Sixty-eight studies (55 cross-sectional, 11 educational interventions and 2 RCTs) with sample sizes between 10 and 2700 were included in the review. Most studies were of poor or fair quality. Performance of pharmacy staff was overwhelmingly reported as poor by study authors. This was the case regardless of geography, scenario used, or assessment framework adopted. Scrutiny on how authors arrived at these conclusions revealed that mnemonic criteria were employed to assess pharmacy staff's diagnostic performance rather than a clinical reasoning approach.

CONCLUSIONS

Potentially important aspects of the decision-making process, such as clinical reasoning, were left unexplored. The number and geographic distribution of the included studies is a strength of this review; however, a validated tool was not employed.

Pharmacy student decision making in over-the-counter medicine supply: A critical incident study

BACKGROUND

Various factors influence decision making in over-the-counter (OTC) medicine consultations, yet limited studies have focused, in-depth, on the thought process of pharmacy staff. This includes pharmacy students as pharmacists-in-training.

AIM

To explore the factors that influence pharmacy students' decisions in relation to OTC consultations and choice of OTC medicine/s.

METHODS

Semi-structured interviews using the critical incident technique were undertaken with ten pharmacy students in Australia, who also worked as part-time pharmacy staff.

RESULTS

Nine key themes were identified to influence pharmacy student decision making in OTC consultations, including customer response, confidence and scope of practice. Product requests were reported as more challenging due to customer expectations and experiences in other pharmacies, states or countries. Although negative customer response influenced some students to supply medicines in contradiction of evidence, an overarching concern for safety meant that a medicine was only supplied if unlikely to cause harm. Students reported developing confidence in OTC decision making more from real-life practice than university training; greater confidence was identified for inquiries more frequently experienced in the pharmacy. Students perceived that customers had assumptions around support staff, and were happier to talk to students than assistants.

CONCLUSION

This study further identified that OTC decision making is a complex process for pharmacy students. Additional opportunities for experiential learning within this area are suggested, such as work-based placements or in-class activities such as role-plays with simulated patients.

Current models of support from community pharmacies for patients on oral anticancer medicines

Administration of chemotherapy is moving into the community as more and more therapies to treat cancer are being developed as oral medications. Patients taking these oral medications still require support, as many of these agents can be toxic. This support could be simple side effect management, compliance issues or even reassurance with regards to their diagnosis as examples. Community pharmacies are ideally placed within the community to help these patients. The purpose of this review is to determine what support community pharmacies are currently providing for patients taking oral anticancer medication and if there is a model that can be adopted or adapted to be used elsewhere. Searches were undertaken using two databases, Medline and Embase. Other evidence-based articles were discovered from other sources. The different services currently available from community pharmacies were largely varied. There are some key aspects to each which could be used in the development of a new model. Further research is required to determine the views of the patients, carers and community pharmacy staff.

Is there a role for community pharmacists in promoting oral health?

AIM

The main aim of the present study was to investigate whether pharmacists recognised that they have a role in the promotion of oral health advice within the community.

METHODS

A cross sectional survey was conducted using a structured questionnaire which was distributed to randomly selected pharmacies (n = 1,500) in the London area.

RESULTS

Six hundred and forty-five pharmacies (43%) responded to the initial invitation and 589 (39%) of pharmacy participants acknowledged that pharmacists should have a role in oral health promotion. Participants from 354 pharmacies (23.6%) subsequently agreed to complete the questionnaire. Of those pharmacies completing the questionnaire, 99.4% of the pharmacy participants recognised that there was a role for pharmacists in oral health promotion. Although 91.5% of the pharmacists reported a fairly high level of knowledge for most of the common oral conditions, they also indicated that they were interested in receiving further training on oral conditions through continuing professional development (CPD) courses. A number of the pharmacies (72.5%) expressed a willingness to incorporate oral health promotion within the NHS pharmacy contract.

CONCLUSION

Pharmacies may be used effectively in oral health promotion by virtue of their frequent contact with members of public. As a result of their established role in promoting and improving the health within the community, it may possible to incorporate oral health within the existing NHS contract.

Is there potential for the future provision of triage services in community pharmacy?

Background

Worldwide the demands on emergency and primary health care services are increasing. General practitioners and accident and emergency departments are often used unnecessarily for the treatment of minor ailments. Community pharmacy is often the first port of call for patients in the provision of advice on minor ailments, advising the patient on treatment or referring the patient to an appropriate health professional when necessary. The potential for community pharmacists to act as providers of triage services has started to be recognised, and community pharmacy triage services (CPTS) are emerging in a number of countries. This review aimed to explore whether key components of triage services can be identified in the literature surrounding community pharmacy, to explore the evidence for the feasibility of implementing CPTS and to evaluate the evidence for the appropriateness of such services.

Methods

Systematic searches were conducted in MEDLINE, EMBASE and International Pharmaceutical Abstracts (IPA) databases from 1980 to March 2016.

Results

Key elements of community pharmacy triage were identified in 37 studies, which were included in the review. When a guideline or protocol was used, accuracy in identifying the presenting condition was high, with concordance rates ranging from 70 % to 97.6 % between the pharmacist and a medical expert. However, when guidelines and protocols were not used, often questioning was deemed insufficient. Where other health professionals had reviewed decisions made by pharmacists and their staff, e.g. around advice and referral, the decisions were considered to be appropriate in the majority of cases. Authors of the included studies provided recommendations for improving these services, including use of guidelines/protocols, education and staff training, documentation, improving communication between health professional groups and consideration of privacy and confidentiality.

Conclusion

Whilst few studies had specifically trialled triage services, results from this review indicate that a CPTS is feasible and appropriate, and has the potential to reduce the burden on other healthcare services. Questions still remain on issues such as ensuring the consistency of the service, whether all pharmacies could provide this service and who will fund the service.

Cellular profile of the peritumoral inflammatory infiltrate in squamous cells carcinoma of oral mucosa: Correlation with the expression of Ki67 and histologic grading

Background

Squamous cells carcinoma is the most important malignant tumor with primary site in the oral cavity and, given the great exposure of mucosa and lips to the etiologic factors of this neoplasm, its incidence is high. Investigation of the prognostic determinants is significant for the expectations of treatment proposal and cure of the patient. The local immune response represented by peritumoral inflammatory infiltrate is a possible prognostic factor.

Methods

In this study, oral mucosa samples of squamous cells carcinoma were analyzed, separated according to their histological classification as well as the phenotypical profile of the cells comprising the peritumoral inflammatory infiltrate was investigated by immunohistochemical method, in addiction, the cell proliferation index via protein Ki67 expression was determinated.

Results

The T lymphocytes made up most of this inflammatory infiltrate, and among these cells, there was a predominance of T CD8 lymphocytes relative to the T CD4 lymphocytes. The B lymhocytes were the second most visualized leucocyte cell type followed by macrophages and neutrophils. The immunohistochemical assessment of Ki-67 positive cells revealed a greater expression of this protein in samples of undifferentiated squamous cells carcinoma.

Conclusion

The results suggest that the cellular immune response is the main defense mechanism in squamous cells carcinoma of oral mucosa, expressed by the large number of T lymphocytes and macrophages, and that the greatest intensity of local response may be associated with the best prognosis.

Mouth ulcers: a study of where members of the general public might seek advice

OBJECTIVE

To investigate where the public seek advice about mouth ulcers and to what extent the public approach the community pharmacy for advice.

SUBJECTS AND METHODS

One thousand members of the general public were randomly chosen and surveyed throughout the day in the main shopping streets of two towns in Israel, Haifa and Tel Aviv. All participants were presented with four standard verbal questions designed to identify reactions to and past experience of mouth ulcers. All responses were recorded immediately on to data sheets and transferred to a computer for analysis of frequencies and percentages and Chi-square analysis.

RESULTS

Nearly one third of those surveyed admitted to a history of mouth ulceration. The vast majority (66-69%) would first approach their general medical practitioner for advice, 13-17% would first approach a general dental practitioner, and only a small minority of the public (4-10%) would first approach the community pharmacy. Lay persons could not distinguish an ulcer with features that would strongly suggest a malignant neoplasm from other types of mouth ulcer.

CONCLUSIONS

The dental profession needs to collaborate more closely with the medical and pharmaceutical professions in order to offer patients better access to information and care.
