Service design for reducing waiting times and improving patient experience in Tanzanian primary-healthcare facilities

Abstract

Across healthcare systems worldwide, long waiting times and unsatisfactory patient experiences continue to signal persistent inefficiencies in service delivery. However, there is the lack of empirically grounded guidance on how service design principles can be applied to reduce waiting times while simultaneously enhancing patient experience in a sustainable and contextually appropriate manner. This study investigates how service design can be applied in Tanzanian primary healthcare facilities to reduce waiting times and improve patient experience, specifically in major urban centres including Arusha, Dodoma, Dar es Salaam, Mbeya, and Mwanza. This study is grounded in service design theory and contemporary services marketing perspectives. It uses positivism, quantitative approach, descriptive and explanatory cross-sectional design. Data were collected through structured questionnaire from 462 patients who were sampled using a multi-stage sampling strategy in primary healthcare facilities in major urban centres including Arusha, Dodoma, Dar es Salaam, Mbeya, and Mwanza. The data were analysed using descriptive statistics and structural equation modelling. The findings demonstrate that service design practices play a pivotal role in enhancing both operational efficiency and patient experience. Well-designed service processes are associated with significantly shorter patient waiting times (β = −0.46, p < 0.001; R² = 0.42), while longer waits substantially undermine perceptions of service quality, responsiveness, and overall satisfaction (β = −0.39, p < 0.001). Service design practices also exert a direct positive effect on patient experience (β = 0.41, p < 0.001), with the model explaining a substantial proportion of experiential variance (R² = 0.58). The partial mediating role of waiting time (β = 0.18, p < 0.001) indicates that efficiency and experience are complementary outcomes of service design. These findings indicate that integrating service design into primary healthcare management is not only an operational improvement tool but also a critical pathway for achieving patient-centred, efficient, and sustainable health service delivery in Tanzania. Accordingly, the study recommends adopting service design as a strategic approach to support more responsive and sustainable healthcare services in Tanzania.
