Audit of Tracheostomy Care Practices in a Nigerian Tertiary Neurosurgical Intensive Care Unit According to Published Guidelines.

INTRODUCTION: Chest infections are a frequently encountered problem in patients admitted to the intensive care unit (ICU), more so in tracheostomised patients. This study aimed to audit the tracheostomy care practices in patients with neurosurgical pathologies in the ICU of Wellington Clinics Abuja, a tertiary neurosurgical hospital in Nigeria.

METHODS: We conducted a closed-loop audit with mixed methods involving analysis of 24 patients who had tracheostomy within the first two weeks of neurosurgical pathology at a tertiary neurosurgical hospital and semi-structured interviews to determine tracheostomy care practices among the primary caregivers - nurses, intensivists, and doctors.

RESULTS: Of the 161 ICU admissions in the first cycle, 22 patients received tracheostomy, 16 met the eligibility criteria. At re-audit (second cycle), eight of 40 patients met the criteria. All the patients received open suctioning through a dual cannula-cuffed tracheostomy tube and had independent portable suction units. In the baseline audit (first cycle), suction catheters were reused for 12-24 hours in each patient and were stored in varying combinations of normal saline and Savlon antiseptic (5 mg of cetrimide (0.5% w/w) and 1 mg of chlorhexidine digluconate (0.1% w/w)). The frequency, technique, and assessment of the need for airway suctioning were inconsistent among caregivers interviewed. All 16 patients had at least one episode of pneumonia, 10 patients had a second episode, and two patients had > two episodes. One mortality was recorded directly attributable to the complications of pneumonia. While in the re-audit, with adherence to recommendations, three patients suffered one episode of pneumonia and only one had a second episode. No mortality was recorded.

CONCLUSION: A standard practice guideline was necessary for tracheostomy care in our ICU. In low-resource settings, stated recommendations such as single-use suction catheters and improved hygienic practices can reduce rates of pneumonia in tracheostomised patients.
