BackgroundKnowledge and skills of primary health care workers (PHCWs) in primary eye care have been demonstrated to be inadequate in several districts of Kenya, Malawi, and Tanzania. We tested whether enhanced supervision, focused on improving practical skills over two years, would raise the scores of these workers on a test of basic knowledge and skills.MethodsThis was a randomised controlled trial. All primary health care (PHC) facilities within two districts of each country were enrolled and randomly assigned by district (Kenya, Malawi) or by health care facility (Tanzania) to receive quarterly skills-based supervision by a district eye coordinator or to continue existing routine supervision. At baseline, a test of basic knowledge and skills in five key areas was administered to PHCWs, and visual acuity (VA) charts and working torches were provided. After two years the test was administered again. Changes in test scores were compared between the intervention (enhanced supervision) and the non-intervention (routine supervision) facilities.ResultsAll 137 facilities in the six districts were enrolled including 343 PHCWs. At baseline, no facility had a visual acuity chart and 18 (13%) had a working torch; the average total skills scores were 6.04 and 6.38 (maximum of 12) in the non-intervention and the intervention facilities, respectively. After two years, 16 intervention facilities (23.2%) had a visual acuity chart correctly placed and 19 (27.5%) had a working torch, compared to 4 (5.9%) and 6 (8.8%), respectively, in the routine supervision facilities. At the facility level, the change in overall test scores was +1.84 points in the intervention sites compared to +0.42 points in the non-intervention sites (p<0.001). Staff turnover included about 75% of the staff by the end of the study.ConclusionThe improvements in the enhanced supervision facilities were very modest and of questionable clinical significance. The low impact of the intervention may be due to the high turnover of PHCWs or high absenteeism. A better understanding of the quality of eye care at PHC facilities and influencing factors are urgently needed before continuing to invest resources in the scale up of this model of task shifting in Africa.
BackgroundPrimary eye care (PEC) in sub-Saharan Africa usually means the diagnosis, treatment, and referral of eye conditions at the most basic level of the health system by primary health care workers (PHCWs), who receive minimal training in eye care as part of their curricula. We undertook this study with the aim to evaluate basic PEC knowledge and ophthalmologic skills of PHCWs, as well as the factors associated with these in selected districts in Kenya, Malawi, and Tanzania.MethodsA standardized (26 items) questionnaire was administered to PHCWs in all primary health care (PHC) facilities of 2 districts in each country. Demographic information was collected and an examination aimed to measure competency in 5 key areas (recognition and management of advanced cataract, conjunctivitis, presbyopia, and severe trauma plus demonstrated ability to measure visual acuity) was administered.ResultsThree-hundred-forty-three PHCWs were enrolled (100, 107, and 136 in Tanzania, Kenya, and Malawi, respectively). The competency scores of PHCW varied by area, with 55.7%, 61.2%, 31.2%, and 66.1% scoring at the competency level in advanced cataract, conjunctivitis, presbyopia, and trauma, respectively. Only 8.2% could measure visual acuity. Combining all scores, only 9 (2.6%) demonstrated competence in all areas.ConclusionThe current skills of health workers in PEC are low, with a large per cent below the basic competency level. There is an urgent need to reconsider the expectations of PEC and the content of training.
Attrition of general nurses trained in trichiasis surgery was high. Surgical productivity of trichiasis surgeons remained too low. It is likely that other approaches are needed to address the burden of trichiasis in the three countries. In terms of recommendations, training of trichiasis surgeons should be done in a "package," including a plan for provision of surgical equipment, continuous support and supervision, and outreach.
