Prevalence and factors associated with psychological morbidity, phantom limb Pain in lower limb amputees

Abstract

BackgroundLower limb amputation can lead to psychological problems.There is a lack of data to evaluate the psychological problems and associated factors in lower limb amputees. AimPrevalence and factors associated with psychological disorder and phantom limb pain in lower limb amputees MethodsIt was a cross-sectional study with a consecutive sampling technique. Patients were assessed on the Hospital Anxiety and Depression Scale (HADS) for the presence of depression and anxiety disorder. DSM-5 diagnostic criteria for substance use disorder were used, andphantom limb pain was diagnosed as defined by Pare. Results103 patients were included in the present study with a mean age of37.7 ± 14.5 yrs. The majorityof patients were males (87.4 %), married (69.9 %), on paid employment (95.1 %), and were of middle socioeconomic status (83.5 %). Most of the patients presented with roadside accident injuries (83.5 %)and had below-knee amputation (58.3 %). As per DSM-5, 38.8 % had a substance use disorder, out of which 35.9 % and 24.3 % had alcohol and tobacco use disorders, respectively. On HADS, 48.5 % had a presence of depressive disorder, and 30.1 % had anxiety disorder. The majority of patients (97.1 %) had phantom limb pain. Those from rural areas reported significantly more frequency of anxiety (x2-5.501; p-0.019) and depressive disorder (x2-7.009; p-0.008). Lower incomehad a significant positive association with depression (r-0.228; p-0.021) and phantom limb pain (U-22.500; p-0.008). ConclusionThe prevalence of psychiatric morbidity in lower-limb amputeeswas very high. The most common psychological morbidity was depression,followed by anxiety disorder and substance use disorders.Our findings reflect that we would benefit by including mental health professionals asintegral members of the multidisciplinary team to do an early psychological assessment and intervention, which would help prevent psychological illnesses and improve quality of life.
