The current COVID-19 pandemic has devastated the improvements in family planning services during the past years. This study assessed the impact of the global pandemic that compromised the provision of family planning services in primary healthcare facilities in Sindh – Pakistan. A retrospective data from District Health Information System (DHIS) before Covid-19 (January – February 2020) and during Covid-19 (March – June 2020) was extracted on the provision of family planning services in primary healthcare facilities in Sindh. The study was conducted to understand the impact of service provision through time-series trend analysis by comparing two health facilities i.e., BHUs and BHU plus facilities on monthly average visits (Jan-Feb average) and differences in percentage change over time on the uptake of short and long-acting family planning methods. The findings suggested that due to lockdown and restrictive mobility, the family planning services have fallen drastically in terms of clients visit the health facility from the onset of the COVID-19 outbreak in the month of March 2020 and remain stagnant till June 2020 as compare to before COVID-19 period. The overall analysis revealed the largest decay in the uptake of family planning methods specifically, pills with 31% and 26% during April 2020 in BHU and BHU plus facilities. On the contrary, uptake of Implants showed 25% and 23% decline in the month of June and May in BHU and BHU plus facilities respectively, compared to the average percentage of the pre-COVID Period. The COVID-19 pandemic has adversely affected the provision of family planning services and steeply decreased the uptake of Pills and Implants in primary healthcare facilities in Sindh. On the contrary, the disruption and decrease in services have provided an opportunity to undertake further research exploration to develop future strategies and policies to combat health challenging situations in such pandemics.
