IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

A mailed postcard intervention did not reduce repeat self-harm presentations in emergency departments. Further research is needed to identify specific patient groups who may benefit from this self-harm prevention strategy.

Area of Science:

  • Psychiatry
  • Public Health
  • Emergency Medicine

Background:

  • Self-harm and suicidal behaviors are frequent reasons for emergency department visits.
  • Individuals presenting with self-harm face an increased risk of subsequent suicidal behavior and mortality.

Purpose of the Study:

  • To evaluate the effectiveness of a postcard intervention in reducing repeat self-harm presentations.
  • To assess the impact of mailed postcards on emergency department attendance for self-harm.

Main Methods:

  • A randomized controlled trial was conducted in Christchurch, New Zealand.
  • The intervention involved mailing six postcards over 12 months to individuals following an emergency department visit for self-harm.
  • Outcomes included the proportion and number of self-harm re-presentations within 12 months.

A Novel Digital Platform for a Monitored Home-based Cardiac Rehabilitation Program

Published on: April 19, 2019

Main Results:

  • No significant difference was observed in the proportion of participants re-presenting with self-harm between the control and intervention groups.
  • The total number of self-harm re-presentations did not significantly differ between the groups after adjusting for prior self-harm history.
  • The postcard intervention did not demonstrate a reduction in repeat self-harm presentations.

Conclusions:

  • The postcard intervention was ineffective in reducing further self-harm among individuals presenting to the emergency department.
  • Findings suggest that this intervention may only be effective for specific subgroups of individuals who self-harm.
  • Further investigation is warranted to identify potential subgroups that could benefit from postcard interventions for self-harm prevention.
