Costs and Its Determinants in Pituitary Tumour Surgery

Implementation of a Standardized Interdisciplinary Perioperative Protocol for Patients Undergoing Transsphenoidal Surgery: Impact on Patient Outcomes

INTRODUCTION

Advances in endoscopic endonasal transsphenoidal surgery have led to improved postoperative outcomes after pituitary adenoma resection, including reduced length of stay, complications and readmission rates, without compromising safety and satisfaction.

METHODS

Our team implemented a perioperative protocol in January 2021 for patients undergoing endoscopic, transsphenoidal pituitary surgery. This study compares preoperative characteristics and postoperative outcomes in 279 patients between 2016 and 2022 (128 preprotocol and 151 postprotocol). Our protocol includes interdisciplinary preoperative evaluations, unified communication, cortisol thresholds for postoperative glucocorticoid replacement, and fluid restriction to prevent delayed hyponatremia.

RESULTS

Median age was 54 ± 17 years with 50.8% female patients. There were 229 (82.1%) macroadenomas (>1 cm) and 50 (17.9%) microadenomas/cysts (<1 cm). Mean diameter was 18 (transverse), 18 (craniocaudal), 16 (anteroposterior) mm. Tumor types included 125 (44.8%) gonadotroph, 46 (16.4%) adrenocorticotroph, 40 (14.3%) lactotroph, 26 (9.3%) Rathke cysts, 19 (6.8%) somatotroph, 13 (4.6%) nondiagnostic, 3 (1%) somatotroph-lactotroph, 3 (1%) mammosomatotroph, 2 (0.71%) null cell, and 2 (0.7%) thyrotroph adenomas. Postprotocol, 74.2% of patients were discharged on postoperative day 1 compared with 46.1% preprotocol (P < 0.0001). Transient arginine vasopressin deficiency decreased from 10.4% (preprotocol) to 4.6% postprotocol (P = 0.101). Hyponatremia occurred in 13.3% pre-protocol and 4.6% postprotocol. Emergency department visits dropped from 9.4% to 3.9%, and readmissions decreased from 7.8% to 2.6%. Persistent arginine vasopressin deficiency affected 2.3% preprotocol and 1.3% postprotocol patients. Cerebrospinal fluid leaks occurred in 8.5% preprotocol and 7.3% postprotocol.

CONCLUSIONS

Implementing an interdisciplinary, perioperative protocol for transsphenoidal endoscopic pituitary surgery improves length of stay while minimizing readmissions and surgery-related complications.

Smartphone Applications for Remote Monitoring of Patients After Transsphenoidal Pituitary Surgery: A Narrative Review of Emerging Technologies

OBJECTIVE

Almost all postoperative assessments for pituitary patients are performed in clinical settings under the supervision of medical providers. With the emergence of telemedicine, however, there are opportunities to monitor these patients remotely. The potential for use of such technologies is inconsistently described in the brain tumor literature, especially for patients with pituitary adenomas.

METHODS

In this comprehensive narrative review, we present the literature for the use of mobile applications (apps) for monitoring of postoperative symptomatology that is specific to patients undergoing pituitary surgery. Our primary research question was: "Which smartphone apps exist in the literature to monitor parameters associated with common complications of pituitary surgery?" Specifically, we search for apps in the literature that facilitate the measurement of parameters associated with adrenal insufficiency, disorders of water imbalance, and visual changes-3 common complications of pituitary surgery.

RESULTS

Twenty-six apps were identified. Fourteen apps pertained to monitoring of visual changes, followed by 9 apps for monitoring water and electrolyte imbalances and 3 apps for monitoring adrenal dysfunction. Novel technologies that were integrated into these apps included digital image-based colorimetry, sonouroflowmetry, visual contrast sensitivity, and lateral flow immunoassays, among others.

CONCLUSIONS

Due to advancing capabilities of smartphone apps, the potential of telemedicine may extend beyond patient appointments. We show that by integrating novel advances in medical technologies from a variety of specialties, it is possible to develop smartphone-based protocols for remote monitoring of patients after pituitary surgery.

An institutional experience in applying quality improvement measures to pituitary surgery: clinical and resource implications

OBJECTIVE

The aim of this study was to report the authors' experience developing a Lean Six Sigma clinical care pathway (CCP) for endoscopic endonasal transsphenoidal operations.

METHODS

Using Lean Six Sigma quality improvement principles-including the define, measure, analyze, improve, and control framework-the authors developed a CCP for endoscopic endonasal transsphenoidal operations, incorporating preoperative, intraoperative, and inpatient and outpatient postoperative phases of care. Efficacy and quality metrics were defined as postoperative length of stay (LOS), presentation to the emergency department (ED) or readmission within 30 days of discharge, and hospital charges. The study included all adult patients who underwent elective endoscopic endonasal resection for pituitary adenoma, Rathke's cleft cyst, craniopharyngioma, pituicytoma, or arachnoid cyst during the sampling period (April 1, 2018, to December 31, 2022).

RESULTS

Two hundred twenty-eight patients met criteria and were included; 94 were treated before and 134 were treated after implementation of the CCP. Differences between groups in age, gender, race, BMI, American Society of Anesthesiologists classification, geographic distribution, preoperative serum sodium, tumor size, adenoma functional status, and prior surgery were not significant. The mean postoperative LOS significantly decreased from 4.5 to 1.7 days following CCP implementation (p < 0.0001); LOS variability also decreased, with the standard deviation declining from 3.1 to 1.5 days. The proportion of patients discharged on postoperative day (POD) 1 significantly increased from 0% to 61.9% (p < 0.0001). Fewer than one-quarter of the patients (23.4%) were discharged by POD 2 prior to the CCP, while 88.8% of were discharged by POD 2 after CCP implementation (p < 0.0001). Rates of 30-day ED presentations or readmissions were not significantly different (2.1% vs 6.0%, p = 0.20, and 7.5% vs 6.7%, p > 0.99, respectively). Mean per-patient hospital costs declined from $38,326 to $26,289 (p < 0.0001), with an associated change in cost variability from a standard deviation of $16,716 to $12,498.

CONCLUSIONS

CCP implementation significantly improved LOS and costs of endoscopic endonasal resection, without adversely impacting postoperative ED presentations or readmissions.

The socioeconomic burden of acromegaly

Acromegaly is a rare and insidious disease characterized by chronic excess growth hormone, leading to various morphological changes and systemic complications. Despite its low prevalence, acromegaly poses a significant socioeconomic burden on patients and healthcare systems. This review synthesizes the current state of knowledge on the psychosocial burden, disability, impact on daily life, and cost of acromegaly disease, focusing on the quality of life, partnership, medical care and treatment afflictions, participation in daily activities, professional and leisure impairment, and cost of treatment for acromegaly and its comorbidities. It also examines management strategies, coping mechanisms, and interventions aimed at alleviating this burden. A comprehensive understanding of the extent of the socioeconomic burden in acromegaly is crucial to develop effective strategies to improve treatment and care. Further research is warranted to explore the myriad factors contributing to this burden, as well as the efficacy of interventions to alleviate it, ultimately enhancing the quality of life for patients with acromegaly.
