Objective:
To determine the benefits associated with brief inpatient rehabilitation for coronavirus 2019 (COVID-19) patients.
Design:
Retrospective chart review.
Setting:
A newly created specialized rehabilitation unit in a tertiary care medical center.
Participants:
Consecutive sample of patients (N=100) with COVID-19 infection admitted to rehabilitation.
Intervention:
Inpatient rehabilitation for postacute care COVID-19 patients.
Main Outcome Measures:
Measurements at admission and discharge comprised a Barthel Activities of Daily Living Index (including baseline value before COVID-19 infection), time to perform 10 sit-to-stands with associated cardiorespiratory changes, and grip strength (dynamometry). Correlations between these outcomes and the time spent in the intensive care unit (ICU) were explored.
Results:
Upon admission to rehabilitation, 66% of the patients were men, the age was 66±22 years, mean delay from symptom onset was 20.4±10.0 days, body mass index was 26.0±5.4 kg/m2, 49% had hypertension, 29% had diabetes, and 26% had more than 50% pulmonary damage on computed tomographic scans. The mean length of rehabilitation stay was 9.8±5.6 days. From admission to discharge, the Barthel index increased from 77.3±26.7 to 88.8±24.5 (P<.001), without recovering baseline values (94.5±16.2; P<.001). There was a 37% improvement in sit-to-stand frequency (0.27±0.16 to 0.37±0.16 Hz; P<.001), a 13% decrease in post-test respiratory rate (30.7±12.6 to 26.6±6.1; P=.03), and a 15% increase in grip strength (18.1±9.2 to 20.9±8.9 kg; P<.001). At both admission and discharge, Barthel score correlated with grip strength (ρ=0.39-0.66; P<.01), which negatively correlated with time spent in the ICU (ρ=-0.57 to -0.49; P<.05).
Conclusions:
Inpatient rehabilitation for COVID-19 patients was associated with substantial motor, respiratory, and functional improvement, especially in severe cases, although there remained mild persistent autonomy loss upon discharge. After acute stages, COVID-19, primarily a respiratory disease, might convert into a motor impairment correlated with the time spent in intensive care.

Specialized Care Centers and Settings-II
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...

For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
