Post-operative pain prevalence, predictors, management practices and satisfaction among operated cases at a Regional Referral Hospital in Dar es Salaam, Tanzania

Abstract

Background: Post-operative pain is an essential component of good surgical patient care plan. In developing countries however, the prevalence of post-operative pain is relatively very high and pain control strategies are not very promising. The objective of this study was to assess post-operative pain prevalence, predictors, management practices and satisfaction among operated cases at a regional referral hospital in Dar es Salaam, Tanzania.

Methods: Prospective hospital based descriptive observational study of operated cases at a Temeke Regional Referral Hospital in Dar es Salaam, Tanzania. Data was collected using a pre-constructed questionnaire and a visual pain intensity scale.

Results: A total of 136 patients were recruited with mean age of 37.1±15 years (range= 14–80 years). The prevalence of pain was 100%, 83.9%, and 36% at 12, 24 and 48 hours, respectively. At 12 hours moderate to worst pain was reported in 95.6% of cases. The main prediction factor for severe to worst pain at 12 hours was orthopaedic procedures (p=0.05, AOR=3.456), while widow/divorced marital status and female sex were negatively correlated to severity of pain (p=0.005, AOR=0.0230 and p=0.000, AOR=0.034, respectively). The commonest drugs prescribed post-operatively were injection pethidine (50.5%) and tramadol (48.9%) and oral tramadol (47.6%). Pain management satisfaction rate was paradoxically high (74.3%), with male sex being the main predictor.

Conclusion: The prevalence of early post-operative pain is very high. Male sex and orthopaedic procedures are associated with severe pain. Surgeons therefore need to prioritize analgesic prescription at early hours following operation to minimize pain and suffering to patients focusing on orthopaedic procedures.
