Abstract
BACKGROUND: Sub-Saharan Africa faces a severe health worker shortage, which community health workers (CHWs) may fill. This study describes tasks shifted from clinicians to CHWs in Kenya, places monetary valuations on CHWs' efforts, and models effects of further task shifting on time demands of clinicians and CHWs.Entities:

Figure 1Model clinic flow. A model clinic was created to examine the effects of shifting various tasks from clinicians to community health workers. The figure depicts the progression of patients through a clinic visit and highlights some of the various services they may require. Percentages indicate the estimated proportion of patients requiring that service, based on interviews with clinicians and the authors’ clinical experience working in Kenyan health facilities. Table 2 displays all assumptions that were used to create the model clinic.

Clinic model - effect of task shifting on health cadre work hours (based on 35 patient visits per day)
| Current scenario a (hours per day) | Ideal scenario b (hours per day) | Difference c (hours per day) | |||||||
|---|---|---|---|---|---|---|---|---|---|
| Health cadre | More efficient | Baseline | Less efficient | More efficient | Baseline | Less efficient | More efficient | Baseline | Less efficient |
| Clinician | 4.7 | 10.2 | 19.8 | 1.8 | 4.1 | 8.2 | −2.9 | −6.1 | −11.6 |
| CHW | 6.3 | 9.3 | 14.5 | 11.0 | 18.8 | 33.2 | +4.7 | +9.5 | +18.7 |
| Total | 9.3 | 19.5 | 38.5 | 11.7 | 22.9 | 47.3 | +1.8 | +3.4 | +7.1 |
This table presents work hours required by each healthcare worker to provide services to 35 patients per day in current and idealized scenarios. The amount of time required for each cadre to complete a service was varied by a factor of two, representing more and less efficiency, to determine the effects of these assumptions in the model. In the baseline current scenario,a clinicians work 10.2 hours per day while CHWs work 9.3 hours per day. In a baseline ideal scenario,b task shifting would result in clinicians working 4.1 hours per day while CHWs would work 18.8 hours per day. With appropriate tasks shifted to community health workers,c 6.1 hours of clinician time would be freed, while 9.5 hours of community health worker time would be added. If healthcare workers were less efficient at performing tasks, this would have a greater effect on potential time savings than if they were more efficient. CHW, community health worker.
