ABSTRACT

Transmission of respiratory pathogens, such as Mycobacterium tuberculosis and severe acute respiratory syndrome coronavirus 2, is more likely during close, prolonged contact and when sharing a poorly ventilated space. Reducing overcrowding of health facilities is a recognised infection prevention and control (IPC) strategy;reliable estimates of waiting times and 'patient flow' would help guide implementation. As part of the Umoya omuhle study, we aimed to estimate clinic visit duration, time spent indoors versus outdoors, and occupancy density of waiting rooms in clinics in KwaZulu-Natal (KZN) and Western Cape (WC), South Africa. We used unique barcodes to track attendees' movements in 11 clinics, multiple imputation to estimate missing arrival and departure times, and mixed-effects linear regression to examine associations with visit duration. 2,903 attendees were included. Median visit duration was 2 hours 36 minutes (interquartile range [IQR] 01:36-3:43). Longer mean visit times were associated with being female (13.5 minutes longer than males;p<0.001) and attending with a baby (18.8 minutes longer than those without;p<0.01), and shorter mean times with later arrival (14.9 minutes shorter per hour after 0700;p<0.001). Overall, attendees spent more of their time indoors (median 95.6% [IQR 46-100]) than outdoors (2.5% [IQR 0-35]). Attendees at clinics with outdoor waiting areas spent a greater proportion (median 13.7% [IQR 1-75]) of their time outdoors. In two clinics in KZN (no appointment system), occupancy densities of ~2.0 persons/m2 were observed in smaller waiting rooms during busy periods. In one clinic in WC (appointment system, larger waiting areas), occupancy density did not exceed 1.0 persons/m2 despite higher overall attendance. In this study, longer waiting times were associated with early arrival, being female, and attending with a young child. Occupancy of waiting rooms varied substantially between rooms and over the clinic day. Light-touch estimation of occupancy density may help guide interventions to improve patient flow.

ABSTRACT

Objective The health systems costs of COVID-19 are high in many countries, including Pakistan. Without increases in fiscal space, COVID-19 interventions are likely to displace other activities within the health system. We reflect on the inclusion of COVID-19 interventions in Pakistan's Essential Package of Health Services (EPHS) and, from a financial optimisation perspective, propose which interventions should be displaced to ensure the highest possible overall health utility within budgetary constraints. Methods We estimated the costs of all 88 interventions currently included in the EPHS and collected published data on their cost-effectiveness. We also estimated total costs and costeffectiveness of COVID-19 vaccination in Pakistan. We ranked all EPHS interventions and COVID-19 vaccination by costeffectiveness, determining which interventions are comparatively least cost-effective and, in the absence of additional funding, no longer affordable. Results The EPHS assumes a spending per capita of US $12.96, averting 40.36 million disability-adjusted life years (DALYs). From a financial optimisation perspective, and assuming no additional funds, the introduction of a COVID-19 vaccine (US$3 per dose) should displace 8 interventions out of the EPHS, making the EPHS more cost-effective by averting 40.62 million DALYs. A US$6 dose should displace a further intervention and avert 40.56 million DALYs. A US$10 dose would partially fall out of the package, displacing four additional interventions. If health spending per capita decreased to US$8, a US$3 dose would still be affordable, but not US$6 or US$10 doses. Discussion Cost-effectiveness is only one criterion considered when deciding which interventions are included in (or removed from) a health benefits package. While displacing certain interventions to create fiscal space for the COVID-19 vaccine may lead to a financially optimal scenario, doing so may be politically unfeasible or socially undesirable. We highlight the difficult trade-offs that health systems face in the era of COVID-19.

ABSTRACT

Early in the COVID-19 pandemic, models predicted hundreds of thousands of additional TB deaths as a result of health service disruption. To date, empirical evidence on the effects of COVID-19 on TB outcomes has been limited. Here we summarise the evidence available at a country level, identifying broad mechanisms by which COVID-19 may modify TB burden and mitigation efforts. From the data, it is clear that there have been substantial disruptions to TB health services and an increase in vulnerability to TB. Evidence for changes in Mycobacterium tuberculosis transmission is limited, and it remains unclear how the resources required and available for the TB response have changed. To advocate for additional funding to mitigate the impact of COVID-19 on the global TB burden, and to efficiently allocate resources for the TB response, requires a significant improvement in the TB data available.
