Parasuicide is common; its treatment depends on its prevention, which in turn depends on accurate identification of those at risk. When the rates of consultation and the number of prescriptions issued each year for patients who had survived parasuicide were compared with those for controls matched for age and sex the patients who had survived parasuicide were found to have attended much more frequently; their pattern of attendance had accelerated up to the time of the attempt and then decelerated. This variation was not seen in the control group. The number of prescriptions received per visit was static in both groups at all times. General practitioners should regard more frequent attendance by patients who already attend often as indicating that those patients are at risk of parasuicide.
蓄意自伤很常见；其治疗取决于预防，而预防又依赖于对高危人群的准确识别。将每年因蓄意自伤幸存患者的就诊率和所开处方数量与年龄和性别匹配的对照组进行比较时，发现蓄意自伤幸存患者就诊更为频繁；他们的就诊模式在自杀未遂前加速，之后减速。对照组未出现这种变化。两组每次就诊所开处方数量一直保持不变。全科医生应将那些本来就经常就诊的患者更频繁的就诊视为其有蓄意自伤风险的迹象。
