Impact of Bundled Intervention on Outcomes of Patients Undergoing Clean Orthopedic Surgeries With Hardware Implants: Small Prospective Randomized Controlled Trial.

Background: Prosthesis-related infections (PRIs) and surgical site infections (SSIs) remain one of the most devastating complications among patients undergoing clean orthopedic surgeries. Prevention strategies are critical to reduce infection rates in orthopedic surgeries. The current study aimed to determine the effectiveness of a set of evidence-based practices (bundled intervention) in reducing the incidence of PRIs and SSIs among patients undergoing clean orthopedic surgeries with hardware implants. Patients and Methods: A prospective, interventional randomized controlled trial was conducted for a period of three years. A total of 597 patients were enrolled, and depending on their Staphylococcus aureus carrier status were categorized into carrier group (n = 98) and non-carrier group (n = 499). Only carrier group patients were analyzed for effectiveness of bundled interventions, after being randomly assigned to two subgroups: interventional carrier group (ICG; n = 50) and non-interventional carrier group (NICG; n = 48). Results: Of the 597 patients, 98 (16.4%) were colonized with Staphylococcus aureus, among whom 9 (19.4%) had methicillin resistance. During follow-up, overall infection rate of 1.1% was observed (PRI, 0.3%; SSI, 0.8%). There was no case of PRI/SSI in the ICG. However, in the NICG, one patient developed SSI because of methicillin-resistant Staphylococcus aureus. An endogenous source of infection was demonstrated by pulsed field gel electrophoresis (PFGE). The SSI rate was higher in the NICG (p = 0.002). In the non-carrier group (n = 499), SSIs/PRIs occurred among 1.2% of the patients, because of organisms other than Staphylococcus aureus. Conclusions: Benefit of bundle intervention approach could be demonstrated. Further studies assessing the effectiveness of the individual components of the bundle can inform clinical practice greatly.

Persistence of SARS-CoV-2 in COVID-19 patients during the second wave of the pandemic in India.

INTRODUCTION: India witnessed the catastrophic second wave of COVID-19 during the summer months of 2021. Many patients with non-resolution of symptoms admitted to dedicated COVID-19 treatment centers required prolonged inpatient care which led to the unavailability of beds for other COVID-19 patients. The objective of this study was to determine the duration of SARS-CoV-2 positivity in moderate and severe COVID-19 patients requiring long-term pulmonary care as well as to find out the association between different variables with the persistence of the virus. METHODOLOGY: A retrospective chart review of clinical and laboratory data of patients with moderate and severe COVID-19 between 1st April 2021 and 15th July 2021 admitted for more than 28 days and requiring long-term pulmonary care was carried out at National Cancer Institute, AIIMS, India. SARS-CoV-2 RNA was detected with real-time reverse transcriptase-polymerase chain reaction-based tests. Data from all consecutively included patients satisfying the selection criteria were presented temporally and analyzed by Fisher's exact test (p < 0.05). RESULTS: All 51 patients tested positive for SARS-CoV-2 RNA at the 5th week of initial laboratory confirmation of COVID-19. The majority of the patients (38; 74.5%) remained positive for viral RNA till the 6th week and the median duration of viral positivity was 45 days. The clinical presentation of SARI at admission was significantly higher among patients with viral persistence till the 6th week (p < 0.05). CONCLUSIONS: The median duration of the viral positivity was 45 days and SARI at admission was significantly associated with viral persistence till the 6th week.
