Infection control challenges in setting up community isolation and treatment facilities for patients with coronavirus disease 2019 (COVID-19): Implementation of directly observed environmental disinfection.

ABSTRACT:

Background

Extensive environmental contamination by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been reported in hospitals during the coronavirus disease 2019 (COVID-19) pandemic. We report our experience with the practice of directly observed environmental disinfection (DOED) in a community isolation facility (CIF) and a community treatment facility (CTF) in Hong Kong.

Methods

The CIF, with 250 single-room bungalows in a holiday camp, opened on July 24, 2020, to receive step-down patients from hospitals. The CTF, with 500 beds in open cubicles inside a convention hall, was activated on August 1, 2020, to admit newly diagnosed COVID-19 patients from the community. Healthcare workers (HCWs) and cleaning staff received infection control training to reinforce donning and doffing of personal protective equipment and to understand the practice of DOED, in which the cleaning staff observed patient and staff activities and then performed environmental disinfection immediately thereafter. Supervisors also observed cleaning staff to ensure the quality of work. In the CTF, air and environmental samples were collected on days 7, 14, 21, and 28 for SARS-CoV-2 detection by RT-PCR. Patient compliance with mask wearing was also recorded.

Results

Of 291 HCWs and 54 cleaning staff who managed 243 patients in the CIF and 674 patients in the CTF from July 24 to August 29, 2020, no one acquired COVID-19. All 24 air samples and 520 environmental samples collected in the patient area of the CTF were negative for SARS-CoV-2. Patient compliance with mask wearing was 100%.

Conclusion

With appropriate infection control measures, zero environmental contamination and nosocomial transmission of SARS-CoV-2 to HCWs and cleaning staff was achieved.

Project description:Respectful maternity care (RMC) is believed to improve women's childbirth experience and increase health facility delivery. Unfortunately, few women in low- and middle-income countries experience RMC. Patient surveys and independent observations have been used to evaluate RMC, though seldom together. In this study, we assessed RMC received by women using two methodologies and evaluated the associated factors of RMC received. This was a cross-sectional study conducted in nine public health facilities in Ibadan, a large metropolis in Nigeria. We selected 269 pregnant women by cluster sampling. External clinical observers observed them during childbirth using the 29-item Maternal and Child Health Integrated Program RMC observational checklist. The same women were interviewed postpartum using the 15-item RMC scale for self-reported RMC. We analysed total RMC scores and RMC sub-category scores for each tool. All scores were converted to a percentage of the maximum possible to facilitate comparison. Correlation and agreement between the observed and reported RMC scores were determined using Pearson's correlation and Bland-Altman analysis respectively. Multiple linear regression was used to identify factors associated with observed RMC. No woman received 100% of the observed RMC items. Self-reported RMC scores were much higher than those observed. The two measures were weakly positively correlated (rho = 0.164, 95%CI: 0.045-0.278, p = 0.007), but had poor agreement. The lowest scoring sub-categories of observed RMC were information and consent (14.0%), then privacy (28.0%). Twenty-eight percent of women (95%CI: 23.0% -33.0%) were observed to be hit during labour and only 8.2% (95%CI: 4.0%-18.0%) received pain relief. Equitable care was the highest sub-category for both observed and reported RMC. Being employed and having completed post-secondary education were significantly associated with higher observed RMC scores. There were also significant facility differences in observed RMC. In conclusion, the women reported higher levels of RMC than were observed indicating that these two methodologies to evaluate RMC give very different results. More consensus and standardisation are required in determining the cut-offs to quantify the proportion of women receiving RMC. The low levels of RMC observed in the study require attention, and it is important to ensure that women are treated equitably, irrespective of personal characteristics or facility context.

Project description:BACKGROUND:Direct observed treatment (DOT) has been implemented in Bhutan since 1997 and currently, it is offered in various model of delivery including a combination of hospital based, home based DOT and ambulatory DOT. Overall, treatment success rate for tuberculosis cases is higher than the global target; however, it is still need to be improved. Evaluation to the implementation fidelity of DOT is important to identify potential rooms for improvement. This study aimed to assess two major components of the program's implementation fidelity: to assess patient's adherence to DOT and explore factors for adherence; to assess provider's compliance with DOT guideline and explore factors for compliance. METHODS:This research used a sequential explanatory mixed method. The conceptual framework of implementation fidelity was adopted to guide this study design. The cross-sectional study of TB patients was enrolled in two hospitals with highest TB load, between September to November 2017 in Bhutan. Interviewer assisted survey was conducted with 139 TB patients who visited the hospital in continuation phase. In-depth interview was then conducted with nine TB patients and four health staffs to explore the barriers and enablers of DOT. RESULTS:Total of 61.9% (86/139) of patients has received DOT at intensive phase. Proportion was higher among MDR-TB cases (100%), and smear sputum positive TB cases (84.7%). In the continuation phase, 5.8% of patients took medicine at hospital, 48.9% at home and the rest 45.3% no longer practiced DOT. More than 90% of patient received correct dosage and standard regimen of anti-TB drugs according to the guideline. The key factors affecting poor adherence to DOT as perceived by patients were; lack of willingness to visit the clinic on daily basis due to long distance, financial implications and family support. However, patient's satisfaction to the quality of TB treatment service delivery was high (98.6%). Providing incentives to the patient was most agreed enabler felt by both health workers and patients. CONCLUSION:In the selected hospital sites, the patient's adherence to DOT and provider's compliance with DOT guideline is partially implemented; the coverage and the duration of DOT is very low, therefore, need to revise and improve DOT model and structure.
