Zimbabwe's hospital referral system: does it work?

Area of Science:

• Public Health
• Health Services Research
• Health Economics

Background:

• The pyramidal healthcare referral system in Zimbabwe, established in 1980 as part of its primary health care (PHC) model, has faced anecdotal evidence of inefficiency.
• Assessing the functionality of this system is crucial for understanding healthcare delivery in resource-limited settings.

Purpose of the Study:

• To evaluate the operational efficiency of Zimbabwe's pyramidal healthcare referral system.
• To analyze the appropriateness of patient admissions and referrals for pneumonia in children and malaria in adults across different levels of care.

Main Methods:

• A retrospective analysis of 227 inpatient records from three hospitals (secondary, tertiary, quaternary) over three months.
• Data collected included patient demographics, diagnoses (pneumonia, malaria), illness severity, and required "intensiveness" of care.
• Inpatient bed costs per night were calculated for each facility.

Main Results:

• A significant proportion of patients admitted for pneumonia and malaria, across all levels of care, presented with mild severity.
• The central (quaternary) referral hospital managed a similar case-mix to the district (secondary) level hospital.
• Inappropriate admissions were common at the highest referral level, with many patients using higher-level facilities as their first or second point of contact.

Conclusions:

• The pyramidal referral network in Zimbabwe does not meet design expectations, evidenced by the central hospital's high cost for treating mild cases.
• Improving the referral system requires strengthening intermediate facilities, refining access to specialist care, and enhancing community-level health professional training.
• Optimizing patient flow and resource allocation is essential for efficient healthcare delivery.
