Patient perception and satisfaction with a smartphone-based teledermatology service initiated during the COVID-19 pandemic at a tertiary care hospital in North India

Background: Telemedicine is being increasingly used to provide healthcare to patients, particularly during the COVID-19 pandemic. Aims: The study aimed to study patient perception and satisfaction with a smartphone-based hybrid teledermatology service initiated during the COVID-19 pandemic. Methods: This was a cross-sectional telephonic survey including patients ?18 years of age who had received a teledermatology consultation. After noting the demographic, clinical and teleconsultation details, patients were administered the Telemedicine Satisfaction Questionnaire and an additional 6-item questionnaire. Patients were also asked to give qualitative feedback and suggestions for improvement using a semi-structured interview guide. Results: We interviewed 201 subjects. The most common diagnoses were pemphigus (27, 13.4%), superficial fungal infections (24, 11.8%), psoriasis (22, 10.9%) and dermatitis (21, 10.4%). The overall mean Telemedicine Satisfaction Questionnaire score was 4.20± 0.71. One hundred seventy-one (85.1%) patients responded that they would use teledermatology services again, while 168 (83.6%) reported satisfaction with the quality of services. A majority of the patients were largely satisfied with the various components involved, though some concerns were raised about the care perceived as not at par with physical consultations, difficulty in procuring medicines, lack of confidence in photographic diagnoses and the lack of a personal touch. Patients with urticaria (P=0.020), those who were advised a change in treatment (P=0.029) and those with improvement in their skin disease (P=0.026) were more likely to be satisfied. Limitations: Our study was conducted during the COVID-19 pandemic when patient acceptability was likely to be higher. Only follow-up patients were included in the study. Conclusion: Patient satisfaction levels were generally high with teledermatology. Addressing lacunae that negatively impact patient perception and satisfaction will help in greater acceptance of teledermatology services.

Identification, synthesis, and characterization of β-isomer as process related impurity in production of methocarbamol from guaifenesin

Methocarbamol is a central nervous system depressant with skeletal muscle relaxant properties indicated to treatspasms. During the synthesis of methocarbamol from guaifenesin, both potential known and an unknown impurity(0.05%–0.1%), high performance liquid chromatography) were observed. The later was separated using preparativeliquid chromatography. Upon the findings of the 1H nuclear magnetic resonance, Mass, and IR spectral analysis, theunknown impurity was designated as a β-isomer of methocarbamol [1-hydroxy-3-(2-methoxy phenoxy) propan-2-ylcarbamate]. The impurity isolation, its structure elucidation, and the potential formation mechanism are discussed.
