Effectiveness of a Patient-Centered Weight Management Model in a Community Pharmacy: An Interventional Study

Driving factors of community pharmacist weight management service: A structural equation modeling approach

BACKGROUND

Even though the effectiveness of community pharmacists in helping customers to reduce weight has been evident, few pharmacists provided weight management services (WMS). To drive community pharmacist WMS provision, factors affecting their intention and WMS provision were important to be investigated.

OBJECTIVE

The present study aimed to explore relationships among pharmacist authority, perceived customer obstruction, WMS performance support, obstacles, and facilitators with intention to provide WMS and WMS rovision using structural equation modeling (WMS.

METHOD

Self-administered questionnaires were utilized to collect data from 302 Thai community pharmacists from December 2022 to March 2023. Structural equation modeling (SEM) was used to explore the influencing factors on pharmacist WMS intention and WMS provision.

RESULTS

Pharmacist authority (r = 0.35), WMS performance support (r = 0.24), and facilitators (r = 0.22) were significantly correlated with community pharmacist WMS provision. Pharmacist authority (r = 0.50), facilitators (r = 0.46), and WMS performance support (r = 0.42) were significantly correlated with community pharmacist intention to provide WMS e structural equation model (SEM), pharmacist authority (β = 0.34) and intention (β = 0.16) significantly influenced WMS provision (R2 = 0.20). Authority (β = 0.49) and WMS performance support (β = 0.28) significantly influenced pharmacist intention to WMS (R2 = 0.42). The model from empirical data indicated a good fit with the hypothetical model (p-value = 0.000, Comparatively Fit Index = 0.9, and Tucker-Lewis Index = 0.878).

CONCLUSION

Pharmacist authority had direct effects with both their intention to provide WMS and WMS provision. WMS performance support had a direct effect on intention to provide WMS and an indirect effect on WMS provision. Facilitators also had significant correlations with intention to provide WMS and WMS provision.

Effect of pharmacist interventions on the management of overweight and obesity: A systematic review

BACKGROUND

Pharmacists are underused healthcare professionals who are well positioned to provide weight management interventions; however, a systematic review of the literature supporting the role of pharmacists in weight management is lacking.

OBJECTIVES

To conduct a systematic review to assess the body of evidence supporting the role of pharmacists in the management of obesity.

METHODS

A literature search of OVID MEDLINE, Embase, Web of Science, and CINAHL was conducted from inception through February 23, 2023, to identify studies involving pharmacist interventions for weight management. Included studies were retrospective or prospective studies reporting a change in body weight, body mass index (BMI), or waist circumference as a primary endpoint; and a weight management intervention involving a pharmacist. Studies were excluded if they did not report the desired outcomes, involved pediatric populations, or lacked a pharmacist in the intervention.

RESULTS

Twenty-nine studies met the eligibility criteria. A total of 6,423 study participants were enrolled with a mean BMI of 27 to 46 kg/m2. The included studies were conducted across 8 different countries with 15 from the United States. The primary approach was a prepost/quasi-experimental study design, typically conducted in community pharmacies. The pharmacists' role varied widely but mainly involved educational counseling as the pharmacist made medication recommendations in only 5 studies. Multidisciplinary collaboration was infrequent. All but 3 studies reported a significant improvement in the weight loss outcome of interest, although most study durations were less than 6 months. A critical appraisal of the 29 studies found the overall quality of the available studies to be relatively poor.

CONCLUSION

Pharmacist interventions for weight management were mostly effective in reducing body weight; however, more robust clinical trials with a comparator group and for longer duration are warranted. The pharmacist's role in managing weight loss medications also requires further study.

Views of patients with obesity on person-centred care: A Q-methodology study

INTRODUCTION

To better accommodate patients with obesity, the adoption of a person-centred approach to healthcare seems to be imperative. Eight dimensions are important for person-centred care (PCC): respect for patients' preferences, physical comfort, the coordination of care, emotional support, access to care, the continuity of care, the provision of information and education, and the involvement of family and friends. The aim of this study was to explore the views of patients with obesity on the relative importance of the dimensions of PCC.

METHODS

Q methodology was used to study the viewpoints of 21 patients with obesity on PCC. Respondents were asked to rank 31 statements about the eight dimensions of PCC by level of personal significance. Using by-person factor analysis, distinct viewpoints were identified. Respondents' comments made while ranking were used to verify and refine the interpretation of the viewpoints.

RESULTS

Five distinct viewpoints were identified: (1) 'someone who listens in an unbiased manner', (2) 'everything should run smoothly', (3) 'interpersonal communication is key', (4) 'I want my independence', and (5) 'support for myself and my loved ones'. Viewpoint 1 was supported by the largest number of respondents and explained the most variance in the data, followed by viewpoint 3 and the other viewpoints, respectively.

CONCLUSION

Our findings highlight the need for tailored care in obesity treatment and shed light on aspects of care and support that are most important for patients with obesity.

PATIENT CONTRIBUTION

Our sample consisted of patients. Patients were also involved in the development of the statement set through pilot testing.
