Impact of Covid-19 pandemic on arthroplasty services and early experience after resuming surgeries at a ‘non Covid’ center

Abstract

\n Background\n The aim of this study is to assess the impact of Covid-19 crisis on hip and knee joint replacement surgeries at a high volume tertiary care hospital in the Indian national capital region and to evaluate the early experience of resumption of arthroplasty services.\n \n Methods\n Institutional records of the arthroplasty cases, operated between 1st March to 31 August of 2019 (Group A, pre-Covid) and 2020 (Group B, pandemic year) were compared retrospectively over numerous parameters including the complications within six weeks of surgery.\n \n Results\n There was a significant drop (by 82.53\u202f%) in the total number of arthroplasty surgeries in Group B (62) as compared with Group A (355). Average number of arthroplasties per month were 59.17\u202f±\u202f12.93 and 10.67\u202f±\u202f13.29 in Group A and Group B respectively (p\u202f<\u202f0.001). There was a significant increase in postoperative complication rate 7/355 (1.97\u202f%) in Group A vs 7/62 (11.29\u202f%) in Group B during pandemic (p\u202f<\u202f0.002), along with a higher 30-days mortality rate 2/355 (3.22\u202f%) vs 2/62 (0.56\u202f%). Pandemic year also saw an increased readmission rate (4.83\u202f%) vs (0.56\u202f%) and postoperative ICU transfer rate (1.61\u202f%) vs (0.56\u202f%) in comparison with pre-Covid year.\n \n Conclusion\n In the pandemic, arthroplasty services got severely affected at our center. With nearly six fold increase in complication rates, higher 30-days mortality and increased readmission rates, caution is advised in resuming arthroplasty surgeries without robust evaluation of cases. Whether undetected Covid −19 infection or poor metabolic disease control due to lockdown can be linked to these results is a matter of further research with larger multicenter studies.\n
