Measuring Health System Responsiveness in a national community health worker primary care program in rural Liberia.

Abstract

As many low- and middle-income countries scale up community health worker (CHW) programs to achieve universal health coverage, ensuring quality as well as access is critical. Health system responsiveness (HSR) is a core domain of quality patient-centred care, but has not been widely measured in CHW-delivered care. We report results from a household survey measuring HSR and health systems quality of CHW-delivered care in two Liberian counties where the national CHW program of Community Health Assistants (CHAs) for communities five kilometres or more from a health center has been implemented. We conducted a cross-sectional population-based household survey in 2019 in Rivercess (RC) and Grand Gedeh (GG) counties, using a two-stage cross-sectional cluster sampling approach. We included validated HSR questions on six responsiveness domains and patient-reported health system outcomes, such as satisfaction and trust in the CHA's skills and abilities. The HSR questions were administered to women aged 18-49 who reported seeking care from a CHA in the three months prior to the survey. A composite responsiveness score was calculated and divided into tertiles. Multivariable analysis using Poisson regression with log link and adjusting for respondent characteristics was used to determine the association between responsiveness and patient-reported health system outcomes. The proportion of individuals rating responsiveness as very good or excellent were similar across all domains within a district, with ratings were lower in RC (23-29%) than GG (52-59%). High ratings in both counties were seen for high trust in the CHA's skills and abilities (GG 84%, RC 75) and high confidence in CHA (GG 58%, RC 60%). Compared with women in the lowest responsiveness tertile (score ≤3), women in the highest tertile (score 4.25) were significantly more likely to report high quality of CHA-delivered care (prevalence ratio, PR=14.1), very good/excellent at meeting health needs (PR=8.0), high confidence in the CHA to provide future care (PR=2.4), and high level of trust in CHA's skills and abilities (PR=1.4). Controlling for respondent characteristics, the composite responsiveness score was significantly associated with all patient-reported health system outcomes (P<0.001). We found that HSR was associated with important patient-reported health system quality outcomes, including satisfaction, trust, and confidence in the CHA. Measuring patients' experience and outcomes of care is important to complement more common measures of technical quality for CHW-delivered care to ensure that this domain of quality is central to community health program design and delivery.
