Pharmacy Technicians' Perception About Symptoms and Concerns of Older Patients Visiting Pharmacies: A Cross-Sectional Study.

PURPOSE: Older patients are still not sufficiently integrated into multidisciplinary care concepts including geriatric and palliative care. They do, however, regularly visit pharmacies to fill prescriptions or to buy self-medication. Thus, they have frequent contact with pharmacy technicians (PTs), who are widely involved in counselling in Germany. However, it is not known whether geriatric symptoms are recognized by PTs and to what extent older patients use their pharmacy to address geriatric or palliative concerns. This study aimed to investigate PTs' impression of older patients' symptoms, geriatric and palliative concerns in consultations, as well as multidisciplinary collaboration. PATIENTS AND METHODS: We conducted a cross-sectional study in April-May 2019. Using a self-administered questionnaire, PTs were asked about (i) geriatric symptoms, (ii) geriatric and palliative concerns older patients expressed in routine consultations, (iii) supposed reasons for inadequate care, and (iv) PTs' desire for multidisciplinary cooperation.
RESULTS: (i) The 5 most common symptoms the 339 participating PTs recognized in the community pharmacy were pain, insomnia, restricted mobility, eye disorders, and constipation. (ii) The three most frequently addressed non-drug-related geriatric palliative concerns were mental strain, loneliness, and mourning. (iii) As reasons for inadequate patient care, PTs predominantly mentioned patient-related reasons (299 of 518 reasons, 58%). (iv) 85% of the PTs desired closer cooperation with general practitioners, 84% with nursing services and 39% with palliative physicians.
CONCLUSION: PTs frequently saw older patients visiting the pharmacy who suffer from a variety of symptoms. PTs were additionally confronted with diverse geriatric or palliative concerns. We deduce, first, a need for PT training in geriatric and palliative care. Second, multidisciplinary care concepts and research should include pharmacies because they seem to be a low-threshold contact to older patients, who might need access to adequate care.

Introduction

Older patients frequently have multimorbidity. They often suffer from life-threatening diseases and multiple symptoms that have a negative impact on their quality of life.1–4 They further frequently have to deal with the death of companions and their own oncoming end of life and increasing frailty.5,6 Additionally, they can be overwhelmed with managing their life and therapy. Geriatric medicine and palliative care address these issues. Both are multidisciplinary overlapping concepts focusing on the quality of life.7,8 They are both holistic approaches that include physical, mental, social and spiritual dimensions of the patients’ health care issues. Initiatives also claim to implement geriatric palliative care as an “interspecialty collaboration” between the two fields.9 However, older patients are still not sufficiently integrated into those multidisciplinary health structures.10 Consequently, strategies have been implemented to close this gap and to identify patients with severe chronic diseases, who would benefit from palliative care. However, although training for this early identification is still limited mostly to general practitioners,11 it is worth looking at other contact points with older patients where they can be transfered to geriatric and palliative care structures.

Older patients and their relatives regularly visit their pharmacies to collect prescriptions or to buy self-medication to treat minor ailments.12,13 With increasing age, patients visit their pharmacy even more frequently than they visit their general practitioner.14 Therefore, pharmacies represent a low-threshold contact point for patients and their relatives. Current pharmaceutical care services contribute to optimizing older patients’ therapy by assisting in administration problems, performing medication reviews or monitoring possible adverse reactions.15,16 Geriatric and especially palliative aspects are considered only to a low extent in current pharmacy services. It is unknown to what extent the pharmaceutical staff recognizes patients’ symptoms during pharmacy consultations. Knowledge about this would allow an estimate of how many patients visiting pharmacies suffer from symptoms and might be inadequately treated. However, no data exist on whether older patients currently address general health issues including geriatric and palliative concerns in their pharmacy consultations. If they do, pharmacies could serve to fill some of the missing connections between older people and geriatric and palliative care resources.

In Germany, pharmacies must be owned and operated by a pharmacist. The supportive pharmaceutical staff includes employed pharmacists and pharmacy technicians (PTs). PTs represent the largest proportion of pharmaceutical staff. To become a PT, they need to pass a two-year program at a specialized PT school and a half year of practical training in a pharmacy. Because of their non-academic qualifications, they work under the attendance and supervision of pharmacists. Within this framework, PTs advise on and dispense prescribed drugs and self-medication and are frequently the patient’s first point of contact in community pharmacies. Especially in the context of counselling in self-medication, the PTs need to clarify the patient’s symptoms to evaluate the limits of self-medication and to recommend an appropriate product. Few studies have addressed the role of PTs in patient counselling, so far. To assure a more realistic and wider view of older patients relating to their everyday enquiries in pharmacies; however, PTs can be an important source.

This study, therefore, aimed to investigate the PTs’ impression of older patients’ symptoms, geriatric and palliative concerns in pharmacy consultations, as well as the multidisciplinary collaboration.

Patients and Methods

Study Design

A cross-sectional study was performed by using an anonymous self-administered questionnaire.

Development of the Questionnaire

An expert panel consisting of three pharmacists with experience in palliative and geriatric pharmacy and research developed the questionnaire, based on the validated Memorial Symptom Assessment Scale (MSAS), an unvalidated questionnaire by Somers et al 2003, and the unvalidated Common Terminology Criteria for Adverse Events (CTCAE), Version 5.0 from the National Cancer Institute.17–19

The final questionnaire consists of four parts ():

(i) Question 1a-c: Geriatric symptoms should include typical geriatric and palliative symptoms as well as common adverse drug events. We defined 20 symptoms based on MSAS, Sommers et al and used the terminology of the CTCAE.17–19 The questions of the MSAS, which addresses the patients themselves, were modified to represent the perspective of PTs. After a pretest, a question about the need for support was added. Frequency was measured via a 5-point Likert scale (none/a few/many/most/all), impairment via a 4-point Likert scale (severe/moderate/mild/no), and the need for support via a 5-point Likert scale (never/rarely/occasionally/often/always).

(ii) Question 2a-b: Geriatric palliative concerns should cover common geriatric, palliative and pharmaceutical issues that are attributed to older patients. For this purpose, the expert panel defined 9 drug-related and 10 non-drug-related geriatric palliative concerns of older patients, based on literature.20–22 To determine the frequency and the need for support, we used the same questions and scales as in part (i).

(iii) Question 3: We additionally asked open questions about the PTs opinions of the reasons for inadequate care.

(iv) Question 4–6: Desire for multidisciplinary cooperation and counselling of older patients: We asked the participants to rank five current activities in the community pharmacy according to their frequency and importance. Closed questions rated the existing cooperation with other professional groups and the desire for more multidisciplinary collaboration. Questions in part (iii) and (iv) were not based on former questionnaires.

Demographic data (Question 7–14, sex, age, profession, professional experience, hours worked per week, hours spent in counselling, size of the pharmacy) were reported at the end of the survey.

The questionnaire was pretested cognitively by nine pharmacists as well as three PTs (target group). Based on the pretest, the phrasing of questions and written instructions for answering the questions were modified to ensure comprehensibility and adapt the vocabulary to the PTs’ level of understanding. Based on feedback from the respondents, the rating scale (question 1a, 1c, 2a, 2b) was extended by adding the middle category “many”/“occasionally” to a 5-point Likert scale. One question was deleted, because its content was beyond the PTs' responsibility, and one open question was deleted because it turned out to be too complex to be answered precisely by the PTs. In part (i), a question about the need for support was added. Questions in part (iv) were modified to reach a better understanding.

None of the pharmacists and PTs involved in the pretest were involved in the development of the study protocol or the main survey. The results of the pretests were not included in the final data analysis.

Participants and Data Collection

We performed this cross-sectional study between April and May 2019 during a voluntary advanced training session for PTs organized by the Lower Saxony Chamber of Pharmacists. We chose this setting to obtain direct access to PTs, who are difficult to reach by other communication channels.

The total training took part in 12 different settings in Lower Saxony and consisted of 6 different, self-standing one-hour lectures: 'high blood pressure – killer on silent soles', 'nutritional supplements with vitamins D and B12', 'self-medication during pregnancy', 'sleeping disorders', 'reasons and therapy for dizziness', and 'home remedy kits for older patients'. The participants received the questionnaire at the end of the lecture about home remedy kits for older patients. None of the topics on the questionnaire were addressed by the lectures.

The inclusion criterion was that the respondents work as PTs in community pharmacies. At least 50% of questions in the questionnaire had to be answered to be included in the data analysis.

The questionnaires were either collected on site by the last lecturer of the day, or sent via fax by the participants themselves.

Data Analysis

The completed paper-based questionnaires were electronically scanned and converted using FormPro3 (OCR system, Leipzig, Germany). Quantitative data analysis was conducted with Microsoft Excel 2016 (Microsoft Corporation, Redmond, Washington, USA). The nominal and ordinal data were computed with absolute numbers (N) and relative (%) frequencies. Missing data were described as “not specified”. Answers in parts (i) and (ii) were analyzed in Likert scales. The individual reports to open questions of part (iii) were classified post hoc independently by two pharmacists and frequency of each reason for inadequate care was analyzed. In part (iv), the respondents’ individual rankings about the importance and extent of every item (1–5) were summarized. The items were then sorted in ascending order based on their sums to build a summative rank of all respondents (1 to 5).

Ethics

This study was conducted using an anonymous self-administered questionnaire. Participants who worked in the health sector were asked about their professional experience. According to the German regulations of ethical standards, ethical approval is necessary only if epidemiological research includes personally identifiable information. This was not the case in this study. The Chamber of Pharmacists of Lower Saxony was informed about the study in advance and gave its consent. Consent to participate in the study was given by voluntarily completing the questionnaire. When returning the questionnaire by fax, it was pointed out that data protection would be respected on the spot. Additionally, faxes were to be returned with the number suppressed.

Results

Respondent Characteristics

In total, all 831 training participants were invited to answer the questionnaire; 361 of them (43%) responded: 340 questionnaires were collected during the training, and 21 were sent by fax after the training. Twenty-two respondents did not fulfill the inclusion criteria (9 questionnaires were filled out by pharmacists and in 13, the respondents filled out less than 50% of the questionnaire).

Three hundred and thirty-nine questionnaires were, therefore, included in the data analysis. Three hundred and thirty-three (98%) of the participants were female, three (1%) male. The median age (Min-Max) of the participating attendees was 43 (18–63) years old; they had a professional experience of 20 (0.75–45) years in community pharmacy and counselled older patients during 50% of their working time (5–100%, Table 1).

Survey Part (I): Geriatric Symptoms

The five most common geriatric symptoms the PTs recognized in the community pharmacy were pain, insomnia, restricted mobility, eye disorders and constipation (Figure 1). Twelve of the 20 suggested symptoms were recognized as generally “severe” by more than one quarter of the respondents (Figure 2). For 13 of the 20 predefined symptoms, more than one quarter of the PTs recognized a need for additional support in most of their older patients (Figure 3).

Survey Part (II): Geriatric Palliative Concerns

As shown in Figure 4, the five geriatric palliative concerns most frequently expressed by older patients in community pharmacies were drug-related: drug therapy options, hospital discharge, drug administration, drug–drug interactions and symptom complaints in context with medication. The three most frequently expressed non-drug-related geriatric palliative concerns were mental strain (45% of the respondents answered that this concern was at least often expressed by their older patients), loneliness (37%), and mourning (31%). The PTs saw a high need for support in drug administration, hospital discharge, drug–drug interactions, activities of daily living, and adverse drug reactions. In 17 of the 19 predefined concerns, more than one quarter of the PTs saw a need for more support in most of their older patients (Figure 5).

Survey Part (III): Reasons for Inadequate Care

Two hundred and sixteen participants gave free-text answers about the reasons for inadequate care. The answers included 518 different reasons. The reasons were categorized into three main categories “Patient related aspects”, “Medical care” and “General framework” and 21 subcategories (Figure 6). The most frequently mentioned reason for inadequate care was the lack of time with 70 (14%) reports. Two hundred and ninety-nine of the 518 reasons (58%) can be summarized as patient-related reasons, 140 (27%) related to the medical care by health care professionals and 79 (15%) to the general framework.

PTs suggested possible reasons for inadequate everyday support for older patients. Open responses to the question were categorized post-hoc: Subcategories are divided into three different main categories: patient-related aspects (black), medical care by health care professional (grey), and structure of care (white).

Survey Part (IV): Desire for Multidisciplinary Cooperation and Counselling Older Patients

PTs are most often involved in counselling on drug therapy (summative rank 1, sum of 1131 points), followed by organizational (rank 2, 1093) and logistical aspects (rank 3, 1059), and counselling on non-drug therapy (rank 4, 971). PTs spend the least time on support and assistance for older patients in their routine (rank 5, 712). According to the rated importance, the summative order is: rank 1 (1307) counselling on drug therapy, rank 2 (1133) counselling on non-drug options, rank 3 (894) support and assistance in everyday life, rank 4 (817) logistic and rank 5 (805) organizational aspects.

Eighty-seven percent (296/339) of PTs expressed the desire for more cooperation with other occupational groups. In particular, the respondents would like to see closer cooperation with general practitioners (85%), nursing services (84%) and palliative care physicians (39%). In addition, 27% of PTs would like more cooperation with nutrition consultants and 28% with social workers (Table 2).

Discussion

Our survey with PTs adds valuable knowledge about the role of community pharmacies in the healthcare of older patients. Beyond the pharmacies’ main tasks of distributing and counselling on medication, older patients seem to use pharmacies as one contact point in the health care system for their geriatric and palliative concerns. Therefore, PTs are aware of a wide range of geriatric symptoms and the need for more support in the context of their pharmaceutical consultations. As barriers to better patient care, PTs most frequently mentioned the lack of time and patient-related reasons. Specific training could make PTs even more sensitive to palliative concerns and symptomatic complaints of older patients. If a potential gap in care occurs, the pharmacist and importantly, the attending physician could be involved more quickly. PTs would like to be able to better support their older patients and to have a closer multidisciplinary collaboration with other health professionals. Hence, geriatric and palliative themes play an important role in routine pharmacy consultations, which should be incorporated more structurally in multidisciplinary care concepts.

Geriatric Symptoms in Pharmacy Consultations

PTs frequently recognize geriatric symptoms in their consultation routine and have to consider them while counselling on self-medication. For certain symptoms, eg, pain, insomnia, eye problems, dizziness and cough, our participants estimated a higher prevalence than has been detected in other studies assessing those symptoms in patients.23–31 These mentioned symptoms are common indications for self-medication,32,33 which could explain why PTs recognized them more frequently in older patients.

However, the PTs perceived some symptoms less frequently than in other studies. Especially for the symptoms of dry mouth and dysphagia, it can be concluded that patients do not address these symptoms in the pharmacy. This is relevant because those symptoms are common adverse drug reactions in older patients (eg dry mouth) or can have a negative impact on adherence (eg dysphagia).34–39 Our results, therefore, suggest that pharmacies should pay more attention to these symptoms to contribute to safe drug therapy.

For more than half of the symptoms, our respondents also recognized an increased need to support the affected patients. This underlines the undersupply of symptoms.40–42 More training in geriatric and palliative care could enable PTs to better recognize symptoms and to involve specialists if necessary.

Geriatric Palliative Concerns of Older Patients in Pharmacy Consultations

As expected in the community pharmacy setting, older patients most frequently express geriatric palliative concerns that directly relate to drug therapy. This was especially the case for drug therapy options, drug administration or drug–drug interactions. These concerns are typically part of pharmaceutical services.43 We additionally included non-drug-related concerns in our survey and asked whether older patients raise them in their pharmacy visits. Although not directly drug-related, these concerns could also be relevant for proper drug therapy.

Older patients frequently have difficulty coping with their various physical, social and psychological challenges. Nevertheless, adequate support is missing.44 It is therefore not surprising that these patients use their local pharmacy to raise non-drug-related geriatric palliative concerns. Mourning was a frequently mentioned concern according to our PTs. Even though it is not obvious, older patients need as much support in coping with mourning as younger patients do.45 This is especially important because mourning also triggers the onset of physical and mental health problems, and can, therefore, have a negative effect on medication adherence.46 In order to better address those patients’ needs in the pharmacy consultation process, all pharmaceutical staff should be qualified in basic palliative care concepts.47

Our respondents also noted that loneliness is mentioned frequently by older patients in the community pharmacy. Loneliness is common in older patients. It represents an important risk factor for depression and anxiety disorders, which also can have a negative impact on adherence.48–52 These examples reflect the valuable information available in community pharmacies and raise the question of how to integrate it more effectively in multidisciplinary palliative and geriatric care.

Better Multidisciplinary Cooperation to Overcome Inadequate Support

According to the responding PTs, patient-related aspects were the main reasons for insufficient support in everyday life. This is in line with the literature: patients want to maintain their autonomy as long as possible and do not want to be a burden to anyone.53,54 With increasing age, more people live alone and support by family members decreases. This results in a lack of family support which needs to be intercepted by the healthcare system.55 Since the PTs in our study also were aware of these barriers, all health care professionals should encourage older patients to talk about their complaints and facilitate support for them.

The lack of time and personnel, as well as various problems in multidisciplinary cooperation (lack of qualifications, lack of local contact persons, neglecting geriatric needs), were also identified by the PTs as reasons for insufficient care of older patients. PTs wish to assist their older patients more with their needs and desire a closer cooperation with other healthcare professionals including palliative specialists. Therefore, based on our results, initiators of palliative care concepts would find open-minded PTs and pharmacies willing to help. This could be seen as a chance to implement requested concepts that improve multidisciplinary cooperation.56 The health system should use available resources to the fullest extent possible, and the information obtained in community pharmacies, and particularly from PTs, should be better integrated into multidisciplinary health concepts.

Limitations

The survey was regionally limited to Lower Saxony, Germany. Generalization of the findings is, therefore, only possible to a limited extent. PTs in other countries may not have the same level of contact with patients. Our survey captured only the PTs’ perspective, and pharmacists’ perspective might differ. It further has to be considered that PTs are not trained to assess geriatric symptoms. Their perspective might, therefore, differ from the patients’ perspective and their actual symptoms. Because of this, our survey is not an objective analysis of older patients’ symptoms and concerns. It further does not present data about actual PT counselling. Nevertheless, our results allow a valuable insight into older patients in pharmacy consultations. Other limitations are that the descriptive analysis does not allow correlations of single items, and due to the respondent rate of 43%, a selection bias cannot be excluded. Data about the PTs who did not answer the questionnaire were not available. It can further be assumed that our participants represent especially motivated PTs, since the survey was carried out within the framework of a continuing education event. We can neither exclude a social desirability bias in the respondents nor that their answers were influenced by the training. Interpreting the results of the survey is further limited because the final questionnaire was not validated. We did not calculate reliability measures such as kappa and Cronbach’s alpha. Nevertheless, the questionnaire was based in part on existing validated questionnaires. For quality assurance, we pretested the questionnaire.

Conclusion

PTs see many older patients in their pharmacy who suffer from a variety of symptoms. PTs are additionally confronted in their daily counselling activities with diverse geriatric or palliative concerns of these patients. We deduce, first, a need for PT training in geriatric and palliative care. Second, multidisciplinary care concepts and research should include pharmacies because they seem to be a low-threshold contact point for older patients, who need access to adequate care.
