Background and aimReoperation rate is defined as the percentage of patients returning to the operating room (OR) within 30 days of an initial craniotomy and undergoing a repeat (redo) craniotomy procedure. It is a key factor of quality-of-care assessments and has implications for outcomes, especially in oncological cases. Redo craniotomies are associated with improvement in neurological status and decreased mortality rate compared to non-surgical interventions but are associated with higher costs and risk of complications. It is important to gauge the indications and frequency of redo craniotomies as an index of quality of healthcare to improve patient outcomes. This study aimed to identify the indications, frequency, and outcomes of reoperation following an initial craniotomy in neurosurgical patients at a tertiary care hospital. MethodsThis retrospective cohort study was conducted at a tertiary care center in Pakistan and included all patients who underwent unplanned reoperation within 30 days of initial craniotomy from January 1, 2010, to December 31, 2017. Demographics, indications for index surgery as well as reoperation, and outcomes in the form of complications, neurological status, and mortality were collected from medical charts and analyzed. ResultsThe study comprised 111 patients who underwent reoperations. Median age of the patients was 36 years (interquartile range {IQR}: 33 years). From a total of more than 1900 annual cases, the frequency of unplanned reoperations was 3.5%. The most common indication of unplanned reoperation based on MRI/CT was hemorrhage (40%, subdural hemorrhage was most common), followed by hydrocephalus (22%), cerebral edema (13%), and residual tumor (13%). The most common clinical reason for unplanned reoperation was a drop in Glasgow Coma Scale (GCS) (59%), whereas anisocoria was seen in 10.8% of patients. The highest mortality rate was observed in patients who were reoperated from post-operative day two to post-operative day seven (56%). Hypertension (p=0.014) and thrombocytopenia (p<0.001) showed significant associations with developing intracranial hemorrhage. Seventy-eight percent of patients showed significant improvement in their Karnofsky Performance Score (KPS) whereas 22% showed deterioration in their KPS. ConclusionThe delivery of consistent quality healthcare relies on early detection and intervention in at-risk patients. Our center's reoperation rate is consistent with the average range among other centers globally. Hypertension, anticoagulation, and antiplatelet therapy were common risk factors for redo craniotomies within 30 days. Patients with these conditions need special care to prevent returns to the operating room. Patients also need to be monitored for hemorrhage in the short term (one to two days) and hydrocephalus in the long term (two to 30 days) to intervene early if needed.
INTRODUCTION Gliomas are the most common malignant brain tumors of the central nervous system in adults. Specialized treatment modalities have improved morbidity and mortality within high-income countries. In lower- and middle-income countries (LMICs), the overall mortality rate is still seen to be alarmingly high. As there is a shortage of statistical data available regarding the epidemiology of these tumors and their management within the country, the objective of this study is to define the landscape of treatment patterns and current epidemiological data regarding gliomas in Pakistan. METHODS As part of the Pakistan Brain Tumor Epidemiology Study (PBTES), data was collected from major neurosurgical centers across the country, consisting of 35 hospitals in all 4 provinces. Our retrospective study looked at patients who underwent surgical procedures for gliomas in 2019, where a surgical pathology was available. The data was collated and analyzed using appropriate statistical methods. RESULTS 791 patients with gliomas were identified (61.8 % in public sector hospitals, 39.1% in private sector). The most common histopathological subtypes were glioblastoma (33.5%), followed by astrocytoma (18.8%) and oligodendroglioma (11.9%). Gender distribution was skewed towards men (65%). The most commonly performed initial surgical procedure was gross total resection (50% in public hospitals, 41% in private hospitals). Private institution hospitals performed surgical biopsies as the first surgical procedure (23%) more often than public hospitals (9%). Regarding adjuvant treatments, only 26% of patients were given chemotherapy, and there was no data regarding 53% of patients. Similarly, only 15% of patients received radiation therapy, and there was no data for 60% of patients. CONCLUSIONS Our study was able to identify the gaps in glioma management within Pakistan, particularly with regards to chemoradiotherapy. Identifying these unmet needs is the first step in developing comprehensive care for glioma patients.
