Randomized Controlled Trial
Impact of COVID-19 primary healthcare service restrictions on patients with chronic obstructive pulmonary disease in Cape Town, South Africa.
Patients with chronic obstructive pulmonary disease (COPD) typically experience multidimensional symptoms throughout the course of their disease, with burdensome physical symptoms, social isolation, and additional psychological suffering. COVID-19 lockdown resulted in restrictions on chronic care delivery at primary healthcare (PHC) facilities, and it is not known what the care experiences of patients with COPD were during this time. ⋯ The COVID-19 lockdown PHC service restrictions caused a disruption to the continuity of care for patients with COPD, with associated worry, anxiety and disappointment. Medication access was largely supported by the home delivery of chronic medication. We suggest that there are opportunities for providing more sustained support for patients with COPD through referrals to community health workers, and also through telephonic patient follow-up by primary care teams.

Previous studies have reported comorbid disease, including hypertension, diabetes mellitus, chronic cardiac and renal disease, malignancy, HIV, tuberculosis (TB) and obesity, to be associated with COVID‑19 mortality. National demographic surveys have reported a high proportion of undiagnosed and untreated comorbid disease in South Africa (SA). ⋯ The study revealed a high prevalence of comorbid conditions among individuals with COVID‑19 admitted to public hospitals in SA. In addition, a significant number of patients had previously undiagnosed hypertension, diabetes, HIV and active TB, and many and poorly controlled chronic disease, as evidenced by high HbA1c levels in patients with diabetes, and high viral loads and low CD4 levels in patients with HIV. The findings highlight the importance of strengthening health systems and care cascades for chronic disease management, which include prevention, screening for and effectively treating comorbidities, and ensuring secure and innovative supplies of medicines in primary healthcare during the COVID‑19 pandemic.

Observational Study
Evaluating the usefulness of the estimated glomerular filtration rate for determination of imipenem dosage in critically ill patients.
Antibiotic dosing in critically ill patients is complicated by variations in the pharmacokinetics of antibiotics in this group. The dosing of imipenem/cilastatin is usually determined by severity of illness and renal function. ⋯ Considering the high mortality rate of sepsis in ICUs and the rapid global increase in antimicrobial resistance, it is crucial to dose antibiotics appropriately. Owing to the variability of antibiotic pharmacokinetics in critically ill patients, this task becomes almost impossible when relying on conventional dosing guidelines. This study found that eGFRs do not correlate with imipenem blood levels in critically ill patients and should not be used to determine the dose of imipenem/cilastatin. Instead, the dose should be individualised for patients through routine therapeutic drug monitoring.
