    In Cambodia, economic development accompanied by health reforms has led to a rapidly ageing population and an increasing incidence and prevalence of noncommunicable diseases. National strategic plans recognize primary care health centres as the focal points of care for treating and managing chronic conditions, particularly hypertension and type 2 diabetes. However, health centres have limited experience in providing such services. This case study describes the process of developing a toolkit to facilitate the use of evidence-based guidelines to manage hypertension and type 2 diabetes at the health-centre level. We developed and revised a preliminary toolkit based on the feedback received from key stakeholders. We gathered feedback through an iterative process of group and one-to-one consultations with representatives of the Ministry of Health, provincial health department, health centres and nongovernmental organizations between April 2019 and March 2021. A toolkit was developed and organized according to the core tasks required to treat and manage hypertension and type 2 diabetes patients. The main tools included patient identification and treatment cards, risk screening forms, a treatment flowchart, referral forms, and patient education material on risk factors and lifestyle recommendations on diet, exercise, and smoking cessation. The toolkit supplements existing guidelines by incorporating context-specific features, including drug availability and the types of medication and dosage guidelines recommended by the Ministry of Health. Referral forms can be extended to incorporate engagement with community health workers and patient education material adapted to the local context. All tools were translated into Khmer and can be modified as needed based on available resources and arrangements with other institutions. Our study demonstrates how a toolkit can be developed through iterative engagement with relevant stakeholders individually and in groups to support the implementation of evidence-based guidelines. Such toolkits can help strengthen the function and capacity of the primary care system to provide care for noncommunicable diseases, serving as the first step towards developing a more comprehensive and sustainable health system in the context of population ageing and caring for patients with chronic diseases.

    Preferences for Enhanced Primary Care Services Among Older Individuals and Primary Care Physicians.
    (Applied health economics and health policy, 2023-05) Ozdemir, Semra; Ansah, John; Matchar, David

    Objective

    We aimed to identify the factors that are most important for community-dwelling older individuals (i.e., users) and primary care (PC) providers to enhance PC services.

    Methods

    Discrete choice experiment surveys were administered to 747 individuals aged ≥ 60 years and 242 PC physicians in Singapore between December 2020 and August 2021. Participants were asked to choose between two hypothetical PC clinics and their current clinic. Latent class models were used to estimate the relative attribute importance (RAI) and to calculate the predicted uptake for enhanced PC services.

    Results

    Based on the attributes and levels used in this study, the out-of-pocket cost (RAI: 47%) and types of services offered (RAI: 25%) were the most important attributes for users while working hours (RAI: 28%) and patient load (RAI: 25%) were the most important for providers. For out-of-pocket visit costs ranging from Singapore dollars (S)$100 to S$5, users' predicted uptake for enhanced PC services ranged from 46 to 84%. For daily patient loads ranging from 60 to 20 patients, providers' predicted uptake ranged from 64 to 91%, assuming their income remains unchanged.

    Conclusions

    Our study provides timely insights for the development of strategies to support the government's new health care initiative (HealthierSG), which places PC at the center of Singapore's healthcare system. The ability to choose their preferred clinic, low out-of-pocket costs and types of services offered (for users), and reasonable working conditions (for providers) were the key factors for users and providers to participate in enhanced PC services.
