In recent years, many issues have been considered when attempting to ameliorate the wellbeing of patients and the efficiency of hospital administration. Patients have often complained about endless waiting lists, low standards of cleanliness, poor hospital food, and unsatisfactory doctor-patient communication and now, according to an expert from a leading image consultancy, doctors dress codes and their general appearance must come under close scrutiny. Of healthcare professionals have an unwashed appearance, dirty nails or unkempt hair, this exudes the impression of recklessness, wearing red reminds patients of blood, and power dressing is discouraged because patients may feel undermined and less relaxed. Although campaign groups approve of healthcare professionals leading by example with high standards of hygiene in hospitals, some individuals argue that this potential new image legislation is merely a case of jumping on the bandwagon of the current media trend for home and lifestyle makeovers.
