COVID-19 death: A novel method of improving its identification when a patient has multiple diagnoses

Assigning a primary cause of death to a deceased patient who had multiple principal diagnoses including coronavirus disease 2019 (COVID-19) is challenging because of the difficulty in selecting the most appropriate cause. To proffer a solution, the authors reviewed the literature on assigning a primary cause of death. In 2015, the Nnabuike-Jagidesa (NJ) model II was devised to improve the International Classification of Diseases and related health problems, 10th revision (ICD-10) guideline on how to assign a primary cause of death. The NJ model II stipulates that when there are multiple diagnoses with no plausible explanation that one of the illnesses could have resulted in the other clinical conditions, the single most appropriate primary cause of death is the condition with the highest case fatality ratio in that setting. In the index report, the authors opine that if the case fatality ratios are similar, the following objective criteria (listed in the order of priority) should be used to assign a primary cause of death: condition with the highest infection fatality ratio, condition that was the main indication for the last acute surgical or invasive procedure performed (during the course of the same ill-health) before the death and the disease that theoretically affects the highest number of body organs. Additionally, a clinical descriptor should be used when none of the objective criteria are satisfied. This novel approach, termed the modified NJ model II, is expected to improve the objectivity and reproducibility of the assigned primary cause of death in a deceased who had multiple diagnoses, which may include COVID-19.

Maternal deaths due to eclampsia in teenagers: lessons from assessment of maternal deaths in South Africa

Background: Eclampsia remains a major cause of maternal mortality, particularly in teenage pregnancies. Healthcare professionals providing antenatal must regard teenagers as a high risk group for the pre-eclampsia-eclampsia syndrome. Setting: Data extracted from the South African Saving Mothers Report: 2014­2016. Aim: To establish the clinical details in teenage maternal deaths owing to eclampsia. Method: Retrospective review of the case records and maternal death assessment forms of teenagers that died due to eclampsia during 2014­2016. Results: There were 47 teenagers (aged 14 to 19 years) who died from eclampsia. Of these 18 out of 47 (38%) deaths occurred in the post-partum period. Forty (85.1%) of the patients had antenatal care. Three (6.4%) had post-partum eclampsia, and of the remaining 44 of the 47 (93.6%), the gestational age at first occurrence of a seizure ranged from 25 to 39 weeks. The blood pressures at the time of seizure ranged from systolic of 131 to 210 mmHg and diastolic of 89 to 130 mmHg. The commonest final causes of death were intracerebral haemorrhage associated with severe hypertension and multi-organ failure. Avoidable factors included transport delays, referral to the wrong levels of health care and poor care by health professionals. Conclusion: Teenage pregnancy is a risk factor for eclampsia-related death; awareness of borderline elevations of blood pressure levels from baseline values (prehypertension levels) and taking following national guidelines on the management of hypertensive disorders of pregnancy will decrease deaths from eclampsia
