Abstract
To map the instruments to measure patient satisfaction with comprehensive medication management (CMM) services and to compare them according to their development characteristics and applicability of patient-reported outcome measures (PRO) measures.
A scoping review was conducted using the methodology proposed by the Joanna Briggs Institute and the PRISMA Extension for Scoping Reviews (PRISMA-ScR). Studies that developed or applied a patient satisfaction measurement instrument in CMM services, published from 1990 onwards were selected. The critical appraisal of the instruments identified was carried out using an 18 item checklist developed to systematically evaluate PRO measures.
A total of 28 studies were selected; in most (17), the applied instruments had been developed by the authors. Nine of them were validated, most of which used open-ended and closed questions in self-administered printed instruments. The best-qualified instrument reached 11 out of the 18 evaluated items, highlighting the difficulty in the definition of the satisfaction construct.
The review made it possible to identify the instruments available to measure patient satisfaction with CMM services and to comparatively highlight their characteristics and psychometric properties. It also pointed out the need to improve or develop a patient satisfaction instrument for CMM services. However, improvement is needed in many of the evaluated domains of the instruments to meet the desirable requirements for a PRO measure. These gaps should be taken into consideration in future research, aiming to build a robust and standardized instrument for the CMM service.
Introduction
Medications are essential for controlling diseases and increasing the population’s quality of life. However, if the medications are inappropriate for the patient, they can increase drug-related morbidity and mortality, consequently impacting individuals and healthcare systems [1]. In response to this social demand, in 1990, Hepler and Strand suggested the professional practice of pharmaceutical care [2]. This practice involves three components—philosophy of practice, patient care process, and a practice management system—and is materialized in society through the comprehensive medication management (CMM) service [3, 4].
The pharmaceutical care philosophy defines that the pharmacist assumes responsibility for the pharmacotherapeutic needs of patients by trying to identify, prevent, and solve so-called drug therapy problems (DTPs), within a line of care centred on the patient and based on building a therapeutic relationship [3, 4]. In this perspective, the patients should be considered as people with knowledge, experience, and values. As a result, they should be integrated as a health team member, participate in health-related decisions, and assume leadership with regard to their pharmacotherapy [3, 4].
The pharmacist evaluates each medication based on its indication, effectiveness, safety, and convenience during the care process. If any DTPs are identified, the pharmacist proposes interventions for resolving them collaboratively with the patient and with other members of the care team. After this stage, the pharmacist monitors the outcomes of the interventions in a longitudinal follow-up process [3, 4]. CMM provision is made possible through a practice management system that lists the resources required, such as a system for recording care, documentation, care infrastructure, human resources, and payment for the service, among others [3, 4].
The CMM service also requires ongoing quality evaluation and monitoring. Following this perspective, Lima et al. [5] developed and validated a set of key performance indicators for the CMM service for outpatients. Among them, there is patient satisfaction. Furthermore, assessing patient satisfaction can clarify the value of pharmaceutical care services in enhancing patient experience with health systems [6].
Although there is no consensus in the literature regarding the concept of patient satisfaction, it can be understood as a multidimensional construct that qualifies the health service offered and assesses the expectations and needs of patients [7]. Gill and White [8] explain this concept through some theories that consider satisfaction as: convergence of the patient’s health guidelines and the provider conditions [9]; consequence of positive individual evaluations of different dimensions of health care [10]; the patient’s personal preferences and expectations [11]; socially mediated expectations reflected in patient health goals [12]; and the primary outcome of the interpersonal care process [13].
The patient satisfaction measure, considered a patient-reported outcome (PRO), represents a relevant humanistic result of patient-centred services [14]. Despite this, there are few instruments available in the literature to evaluate patient satisfaction with the CMM service, making it difficult to compare services for this parameter [15]. Given this context, it becomes relevant to identify the instruments available to assess the satisfaction of patients followed up in CMM services, and the scoping review is an adequate tool for this.
Considering this, the authors of this review carried out a previous search in the Medline and Cochrane databases in May 2021 and did not find any review on the subject. This fact led to a scoping review to map and analyse available instruments for measuring patient satisfaction observed in CMM services. More specifically, this review aims to answer the following questions: what satisfaction measurement instruments are available for patients seen in CMM services? What are the characteristics of the instruments concerning reliability, validity, and responsiveness?
Methods
This scoping review followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews [16] (Appendix 1) and the Joanna Briggs Institute Manual for Evidence Synthesis [17]. The review protocol was previously published [18] and registered on the Open Science Framework (OSF) platform (10.17605/OSF.IO/RZA38).
Search strategy and formulation of the research question
A search strategy was prepared [17], with the aim of identifying studies that answer the following question: what satisfaction measurement instruments are available for patients followed up in CMM services?
The following electronic databases were searched: MEDLINE, Latin American and Caribbean Health Sciences Literature (LILACS), EMBASE, Cochrane, Scopus, CINAHL, and Web of Science. The electronic search strategy for each database was carried out as shown in Appendix 2. The search strategy combined text words and indexed terms related to pharmaceutical services and patient satisfaction, and was validated using the Epistemonikos database and Google Scholar® (more details on how the validation of the terms was performed in Resende et al. [18]).
A search in the gray literature was also conducted in two Brazilian electronic databases of theses and dissertations (Brazilian Catalog of Theses and Dissertations and Digital Library of Theses and Dissertations). A manual search was performed in the references of the included studies and in the journal with the highest number of published studies retrieved by the initial search strategy.
Study screening and selection
Mendeley® software was used to identify and exclude duplicates. The selection of studies was performed on the Rayyan® platform [19] by a pair of independent reviewers (LCR; CR) in two steps: (i) titles and abstracts screening; and (ii) full-text reading of the studies selected in the previous phase. Disagreements were resolved by a third reviewer (MMGN). Exclusions in the last phase of study selection were documented.
Considering the PCC (participants, concept, and context) strategy suggested for scoping reviews, the adopted inclusion criteria were: (i) participants: patients who are aged 18 or older, or their caregivers, followed in a CMM service [4]; (ii) concept: instruments to measure patient satisfaction with CMM services, both studies that developed/outlined an instrument to assess patient satisfaction and studies that applied (validated) these instruments in clinical practice were included; (iii) context: any clinical practice settings; (iv) study type: methodological studies for the development of instruments to measure patient satisfaction and qualitative, experimental, quasi-experimental, and observational studies in which patient satisfaction was evaluated using an instrument; and (v) publication date: studies published from the year 1990 (the year in which the pharmaceutical care practice was proposed by Hepler and Strand) [2]. There were no language restrictions.
In this review, the following definition for the CMM service was adopted:
(…) the standard of care that ensures that each patient’s medications (whether prescribed, nonprescription, alternative, traditional, vitamins, or nutritional supplements) are individually evaluated to determine whether each is appropriate for the patient, effective for the health condition, safe for comorbidities and other medications in use, and which can be taken by the patient as intended. The CMM includes an individualized care plan that achieves the intended goals of therapy with appropriate follow-up to determine actual patient outcomes. All of this occurs because the patient understands, agrees to, and actively participates in the treatment regimen [4]. (p. 5).
The exclusion criteria were: (i) type of publication: book chapters, letters, editorials, notes, and abstracts with insufficient information for eligibility analysis; (ii) study type: reviews and study protocol; (iii) type of participants: studies carried out to identify satisfaction from the point of view of health professionals; and (iv) type of pharmaceutical service: medication reconciliation, transition of care, disease state management, medication review, guidance on correct medication use, pharmaceutical education, health condition screening, or dispensing services. Studies and instruments not publicly available were requested from their authors. Those which were not made available even after request were excluded from the evaluation.
Data charting, synthesis of results, and comparative analysis of the instruments
Data extraction and evaluation of the instruments were performed by two independent reviewers. All disagreements were resolved by consensus between the two reviewers. The data extraction methodology was validated using two studies that met the inclusion criteria.
The following information was extracted using a spreadsheet in Excel: authors; year of publication; country; objective; definition of the CMM service; and validation characteristics. For all the original instruments (validated by the authors of the studies), other characteristics were extracted: mode of administration (self-applied, by the service provider, or by third-party interview); format of administration (printed or digital); type of questions (Likert scale, open-ended or dichotomic), and number of items.
All the original instruments were evaluated using a checklist developed by Francis et al. [14] to evaluate PRO measures and to identify their strengths, weaknesses, and applicability. It is suitable for carefully measuring satisfaction with health care services and includes practical aspects of instrument administration [14]. The checklist was developed based on six fundamental attributes [14]: (1) conceptual model, in which the instrument must clearly define the construct to be measured and the target population; (2) content validity, where evidence is sought that the PRO measure is adequate for its intended use, generally using interviews with the target audience to assess the clarity of the questions and concepts addressed; (3) reliability, where the degree to which the scores are free of random errors was evaluated, through the analysis of internal consistency or test–retest; (4) construct validity, where it is evaluated whether the test measures the proposed theoretical concept and possible inferences through factor analysis or measures of responsiveness to change, when applicable; (5) scoring and interpretation, which evaluates the instrument’s scoring system and the clarity with which the author explains the meaning of the score obtained; (6) respondent burden and presentation, which refers to the time and effort required from the respondent or those administering the PRO measurement instrument, including the literacy level required to understand the questions raised.
For each attribute addressed, the checklist presents several questions that are scored a zero or one point according to the absence or presence of the criterion. Therefore, the checklist score ranges from 0 to 18 points, in which the higher the score the better the instrument. The maximum value, in turn, corresponds to the fulfillment of all the desirable requirements for a PRO measure. It is important to point out that this instrument does not present stratification of the scores [14].
Results
A total of 5280 studies were retrieved by searching the selected databases. After excluding 1764 duplicates, 3516 titles and abstracts were evaluated. A total of 91 studies were selected for full-text reading but five of them could not be retrieved. Therefore, 86 studies were evaluated for eligibility and 20 of them met the inclusion criteria. The search in gray literature and a manual search retrieved 14 additional studies, eight of which were eligible. In total, 28 studies were included (Fig. 1). Agreement between reviewers was assessed and reached 95.9% with a Kappa index of 0.872, which demonstrated a very good agreement strength [20].

Study characteristics
Table 1 shows the main characteristics of the 28 included studies [15, 21–47]. A high number of studies (n = 12; 42.9%) were conducted in North America [15, 21, 23–25, 27, 41–45, 47], with 10 of these (35.7%) [15, 21, 23, 25, 27, 41–44, 47] developed in the USA. The publication year of the studies ranged from 1998 [23] to 2022 [47] with the majority (57.1%; n = 16) [15, 21, 27, 28, 31, 32, 35–39, 41–44, 46] concentrated between 2010 to 2019. Six different terms for the definition of the service offered were used, highlighting the term “Pharmaceutical Care”, presented in 15 studies (53.6%) [21, 23–26, 28, 30–35, 37, 40, 45].

*Dichotomic = yes or no questions.
**The instrument was applied by a third partial and the format (printed or digital) was not described by the authors.
Most of the original and validated instruments (seven of nine; 77.8%) [15, 21, 22, 24, 25, 27, 28] were self-administered. All instruments had closed-ended questions and six (six of nine; 66.7%) [15, 21, 22, 26–28] open-ended questions. All instruments were validated with respondents who received CMM services, except the questionnaire developed by Larson et al. [25], which was applied to patients who frequented the community pharmacy but without experiencing the CMM service.
The comparative analysis of the instruments through the checklist developed by Francis et al. [14] is presented in Table 3. The instrument by Armando et al. [21] obtained the highest score, reaching 11 out of 18 points under analysis, followed by the instrument by Larson et al. [25] (10 points) and Moon et al. [15] (10 points).

During the evaluation of the conceptual model attribute, it was identified that the definition of the construct “satisfaction” was described for four instruments (four of nine; 44.4%) [21, 22, 25, 26]. The intended respondent population (outpatients) was described for only two instruments [23, 26]. For five instruments (five of nine; 55.6%) [15, 22, 24–26], the authors previously defined that one or more scales were expected.
In the content validity evaluation, the description of the construction methodology of all instruments was identified, which included the participation of experts in their development. For more than half of the instruments (five of nine; 55.6%) [15, 21–24], the respondent population was also involved during their development.
Reliability evaluation was performed for most of the instruments (n = 8) [15, 21–25, 27, 28], and the internal consistency analysis was adopted in all of these cases, involving the calculation of the Cronbach’s alpha coefficient. For two instruments [22, 23], the reliability value did not reach adequate indexes (≥0.70).
The construct validity for the instruments was poorly described by their authors. In the four studies [15, 21, 24, 25] that performed this evaluation partially, factor analyses to identify the relationship among the proposed questions were carried out. With regard to responsiveness to change, the inability to measure changes in patient satisfaction over time was reported for only one of the instruments [21].
For the scoring and interpretation attribute, the instruction on how to reach the final score for the questionnaire was presented for only two instruments [21, 25], although the score’s interpretation was not described. In addition, a management plan for missing responses was not observed for any of the instruments evaluated.
In the respondent burden and presentation attribute evaluation, the response time was considered adequate for all instruments, since the instruments were simple, they had few questions, and most of their questions were closed. Only two studies described the educational level required to answer the instruments, namely 9.52 years of study for Gourley et al. [23] and 8.5 years of study for Moon et al. [15] Furthermore, it was observed that most of the instruments (n = 7; 77.8%) [15, 21, 23–25, 27, 28] were published in their totality in the original study; the other two [22, 26] were not fully published and were obtained only after direct request to the corresponding authors by e-mail.
Discussion
This scoping review, to the authors’ knowledge, was the first to map, identify, and compare the characteristics of patient satisfaction measurement instruments for CMM services available in the literature. Measuring patient satisfaction, a humanistic outcome indicator, in a patient-centred service such as CMM is of great relevance, especially as health systems seek to implement outcome-based payment models [5, 48].
Regarding the place of origin of the included studies, the results show a predominance of publications in the USA (n = 10), which can be explained by this country being the birthplace of Pharmaceutical Care practice [2]. The implementation of the service in the USA was also driven by the Medicare Part D health insurance coverage in 2006, as reported by Gray et al. [49].
The retrieved studies show a wide variation of terms to describe the CMM service, but there was a predominance of the use of “Pharmaceutical Care”, consistent with the largest volume of publications in the USA, where the term was created. The term CMM was used in more recent studies [15, 43, 47].
Among the retrieved studies, the use of instruments translated and adapted from another language was frequent, with a predominance of the instrument developed by Larson et al. [25] (n=10). The instrument divides the questions into “Friendly Explanation” and “Managing Therapy,” where the first deals with aspects of care and staff attitude, while the second involves the pharmacist’s responsibility regarding the pharmacotherapy of their patient. Although it scored only 10 out of 18 points on the PRO measures assessment score, the wide applicability of the instrument may have motivated a greater number of translations and cultural adaptations.
Most of the original validated instruments were self-administered (n = 7), which is consistent with the recommendations for PRO measures instruments, leading to more reliable answers from the patient. The instruments proposed by Gourley et al. [23] and Lyra Júnior et al. [26] were applied through interviews conducted by previously trained professionals, which can compromise the veracity of the information due to the patient’s embarrassment before the interviewer, as reported by Aspinal et al. [50] Moreover, the results of high satisfaction commonly found in clinical service evaluations can be compromised by the so-called gratitude bias, in which the patient is grateful for the simple fact of being guaranteed the service and tends to exaggerate the positive responses, as described by Alves and Trad [51]. The interview format could potentiate this tendency, inhibiting negative answers from the patient.
It was also observed that the use of closed and open-ended questions was adopted for most of the instruments (n = 6), which is in accordance with the recommendations when dealing with quantitative and qualitative methods in measuring satisfaction: the former tends to be reductionist and does not always translate what the user expresses; and the latter may inhibit negative responses in the personal meeting with the interviewer, besides requiring more time for collection and analysis. The combination of the two methods can bring complementarity to the research and avoid the effect of high satisfaction [51].
In general, the instruments did not completely fulfill the desirable standards for measuring patient satisfaction according to Francis et al. [14], showing a low total score for the checklist. The description of the construct “satisfaction” to be measured was absent or superficially described, contrary to what is recommended [14]. Without a clear definition, respondents may have different ideas about the concept, which may impact the measured result [52]. However, the lack of a theoretical definition for satisfaction with health services is recognized, and, although several authors have dedicated themselves to the topic, there is no consensus on the concept [50].
Also, no definition of the intended respondent population was presented for most of the instruments (n = 8), leaving room to use the instrument in any profile of the population. The literature highlights some patient profile factors that may impact the measure of satisfaction with a health service. Age is one of these factors: older patients often tend to be easier to please and to have lower expectations, which can lead to a higher degree of satisfaction. It is also known that women tend to be more critical of healthcare services [53]. Studies in Brazil have also shown that people with lower incomes tend to be more satisfied with healthcare services [53]. Therefore, it is very important to clearly define to which respondents the instrument is intended.
Another factor that can lead to bias in satisfaction measures is related to temporality: surveys applied in healthcare services right after the service is offered are aimed at the user’s concrete experience, avoiding memory bias. However, the answers are more associated with the provider-patient relationship and the explanations received by the user during the consultation. In contrast, some authors state that patients tend to be more critical of the services over time or remember more negative aspects, which are usually more striking, compromising late-answered surveys [51]. None of the instruments evaluated in this study clearly defined the recommended temporal circumstances for the application of the instrument, which may compromise the results.
With respect to the development of the instrument, a little more than half (n = 5) of the instruments evaluated described the participation of the respondent population in its development, recommended to ensure content validity, as well as clarity and understanding of the questions by the intended population [54]. The absence of an analysis of the literacy level of the survey by a large part of the instruments (n = 7) contradicts literature recommendations, since socio-economic and cultural differences of the population may require adaptations of the PRO measures, adapting them to the educational level of the patients investigated [51].
Regarding the assessment of the psychometric properties of the instruments, it was observed that they focused mainly on reliability tests that designate the level at which results are free of random errors. This gap implies that there was no assessment, e.g. of responsiveness to change when the same instrument is used to reassess the service after an intervention. The absence of this criterion is particularly important for researchers seeking to compare the effectiveness of interventions [14]. Also, the following tests were not performed for any of the instruments: the performance of “convergent validity” tests, which compare the instrument with other models that measure the same construct; or the “divergent validity” tests, which require the questionnaire to differentiate notably different groups.
Concerning the interpretability of the answers obtained, all the instruments evaluated demonstrated fragility in this aspect. For instance, there was no description of the meaning of the scores obtained in the instrument, indicating, e.g. a cutoff point from which it is necessary to improve the service due to the negative answers of the respondents. Considering also that most of the instruments are self-administered, it is necessary to consider possible failures in the complete or partial return of the document, and none of the authors presented a plan to treat the missing answers, as recommended in the literature [14].
Considering all the points evaluated in the proposed checklist, it is worth emphasizing the instrument developed by Armando et al. [21], which achieved the highest score in this analysis (11 points). The authors developed a simple instrument with 10 closed questions and one open-ended question, self-administered, to evaluate satisfaction as a humanistic result of CMM services offered in Spanish pharmacies. To this end, they counted on the participation of experts and patients in its development. The validation carried out with 103 respondents involved the reliability test and factor analysis that showed that all items are correlated (single factor). It was distinguished from the other instruments because it was the only one that reported as a limitation the absence of responsiveness to changes, and, therefore, it is believed that it should not be used to measure improvements in the services evaluated.
The instrument developed by Larson et al. [25], in contrast, which achieved second place in the score (10 points), is more extensive, presenting 20 self-applied closed questions. As a limitation, patients were not involved in its development. Therefore, face validity and clarity of the questions were not evaluated, but a robust validation resulted in high reliability (Cronbach’s alpha of 0.873). The authors point to a “before and after” measurement of the CMM implementation as the most suitable use for the instrument, although they did not perform tests to ensure the responsiveness of the questionnaire to changes, such as test–retest. It is important to emphasize that the instrument was answered by people who had not been included in CMM services, but were habitual in the pharmacies investigated, which is a limitation of the study. It is worth reflecting on the construct that was evaluated in this case: satisfaction with the service or expectation. Aspinal et al. [50] assert in their study that there is no consensus in the literature on the relationship between satisfaction and expectation, with divergent results on this topic. Those authors question whether the results of satisfaction surveys really reflect a quality service or just a better service than expected. In the specific case of the instrument developed by Larson et al. [25], the positive responses may be impaired by low expectations of a service that the patients did not even experience. However, the authors justify that the objective of the study was the development of the instrument and not exactly the measurement of satisfaction with the CMM service.
The instrument developed by Moon et al. [15], which also ranked second in overall score (10 points), proposed to briefly evaluate, in 10 closed questions and one open-ended question, three domains related to CMM satisfaction: 1. needs to be related to medication; 2. the role of the pharmacist from the patient’s point of view; 3. overall satisfaction with the service. The instrument was developed by specialists and modified after focus groups with patients. It stands out from the other two highest-scoring instruments because it was the only one that assessed the respondents’ level of literacy (8.5 years). It was submitted to a new psychometric evaluation by Campbell et al. [47] in 2022, who concluded that it should not be used on a large scale to compare the quality of the CMM services provided, although it may be useful to monitor patient satisfaction as an indicator of the quality of a specific service.
As limitations of this review, we can cite the extensive variety of terms to refer to clinical pharmaceutical services. There is great difficulty in standardizing the service provided, making it difficult to find an instrument to measure satisfaction specifically for CMM services. In addition, some studies did not contain complete information for understanding the type of service offered, did not present the measurement instrument in full, or were published only as conference abstracts, without sufficient data for eligibility analysis, even after several attempts to contact the authors. A methodological limitation was conducting the search in the gray literature only in two Brazilian theses and dissertation databases, due to restricted access to other international databases. Another limitation of the present review was the lack of description of information on determining the sample in the included studies or the methods used in the adaptation or validation of the instruments used in these studies.
As a strength of the study, we highlight the high sensitivity of the search strategies used, which involved different terms potentially associated with the CMM service in seven different databases, in addition to the search in the gray literature and an extensive manual search, aiming to avoid possible publication biases in mapping the literature on the subject. Furthermore, the study was conducted according to the methodology recommended by JBI [17] and PRISMA [16] and with several validation phases, conferring robustness to the search and selection method.
The review shows that there is room for improvement of the identified instruments to meet the requirements for a PRO measure. We emphasize as main points for adjustment the need for a clear definition for the construct “satisfaction” to be measured, as well as the description of the intended respondents; the guarantee of involvement of the intended population in the development of the instrument; the validation of the instruments to measure changes over time; and the clear definition of how to score the instrument, including cutoff points that signal the need for intervention in the care process.
These gaps identified in the development of instruments for measuring satisfaction with CMM services should be taken into consideration in future research, aiming to build a robust and standardized instrument for the service.
Conclusion
The scoping review made it possible to identify the instruments available for measuring patient satisfaction with CMM services, an important humanistic indicator. It was also able to comparatively highlight the characteristics and psychometric properties of the originally validated instruments and point out those that most frequently met the desirable criteria for this type of instrument (PRO measure). However, improvement is needed in many of the evaluated domains of the instruments to meet the desirable requirements for a PRO measure. These gaps should be taken into consideration in future research, aiming to build a robust and standardized instrument for the CMM service.
